What Is a Corn Planter?

Corn seeder refers to the planting machinery that takes the crop corn seeds as the object (also taking into account soybeans and other crops). Generally, the name of the seeder is often named by the type of the crop, such as corn seeder, grain drill, corn hole drill, cotton Seeder, forage spreader, etc.

In 101, China has promoted the use of radon, the earliest seed drill in the world, and it is still used in northern dryland areas today.

The first seeder was made in Greece in 1636. In 1830 the Russians made plough drills on animal ploughs. After 1860, Britain and the United States and other countries began to produce animal grain drills in large quantities. After the twentieth century, traction and hanging grain drills and seeders using pneumatic seeding have emerged. Development of precision seeders in the 1950s. China introduced grain seed drills and cotton seeders from the 1950s. In the 1960s, it was successively developed into a variety of types such as hanging grain seeders, centrifugal seeders, universal rack seeders, and air-suction seeders, and developed into milled seeder. By the 1970s, two series of general-purpose sowing machines and combined grain seeders had been formed, and precision seeders had been successfully developed.

The first seeder in Europe was made in Greece in 1636. In 1830, the Russians added a seeding device to a ploughshare plough to make a plough drill. Britain, the United States and other countries began to produce large quantities of animal-powered grain drills after 1860. After the 20th century, traction and hanging grain drills and seeders using pneumatic seeding have emerged. The first centrifugal seeder appeared in Norway in 1958, and various precision seeders were gradually developed after the 1950s.

China introduced grain seed drills, cotton seeders, etc. from abroad in the 1950s, and successfully developed a variety of models such as hanging grain seeders, centrifugal seeders, universal rack seeders, and air suction seeders. And successfully developed a grained seed metering device. By the 1970s, seeding had taken shape

The corn seeder has the characteristics of uniform seeding, uniform depth, stable line spacing, good soil coverage, seed saving, and high work efficiency. The following 10 points should be mastered when using the planter correctly:

1 Maintenance before entering the field should clean up the sundries in the seed box and the weeds and soil on the opener to ensure good condition, and lubricate the transmission and rotating parts of the tractor and seeder according to the instructions Oil, especially pay attention to the lubrication and tension of the drive chain and the tightening of the bolts on the planter before each operation.

2 The rack cannot be tilted. After the seeder is connected to the tractor, it must not be tilted. The rack should be horizontal before and after work.

3 Do a variety of adjustments According to the instructions in the instruction manual and agronomic requirements, adjust the seeding amount, the row distance of the ditcher, and the depth of the ditching soil-covered compression wheel.

4 Pay attention to adding seeds to the seed box to ensure that the seeds are effective. Second, the seed box should be added at least to cover the entrance of the seed box to ensure smooth seeding. .

5 Trial sowing In order to ensure the quality of seeding, before conducting large-area sowing, you must insist on trial sowing 20 meters and observe the working condition of the seeder. Ask agricultural technicians, local farmers, etc. for testing and consultation, confirm that they meet local agronomic requirements, and then conduct large-scale sowing.

6 Pay attention to the straight-line driving of agricultural machinery. The operator should choose the working walking route. It should ensure that the seeding and machinery are easy to enter and exit. When sowing, pay attention to moving straight at a uniform speed. If it is blocked, the planter should be operated while it is moving, and the planter should be lifted when going backwards or turning.

7 First sowing the ground first, so as not to harden the ground, resulting in too shallow depth.

8 Always observe the working conditions of the seeder, ditcher, cover and transmission mechanism when sowing. If clogging, clay, weeding, and inadequate seed coverage, remove them in time. Adjustments, repairs, lubrication or cleaning of weeds must be done after stopping.

9 Protecting machine parts When the planter is working, it is strictly forbidden to reverse or make sharp turns. Lifting or lowering of the planter should be performed slowly to avoid damage to the machine parts.

10 Note that the seeds in the seed box must not be less than 1/5 of the volume of the seed box during the operation of the seed box; when transporting or transferring the plot, the seed box must not contain seeds, let alone other heavy objects.

1 The seed meter does not seed. The main reason is that the transmission gear is not meshed, or the square hole of the seeding shaft and seeding gear is worn, and it is adjusted, repaired or replaced.

2 The individual seeder does not work. The reason is that the seed scaffold or the seeder opening in the individual seed box is clogged with debris, and the debris should be cleaned up; the connection pin of the seed seeding shaft and the individual seed groove is broken, and the pin should be replaced; the individual seed box insert board If it is not pulled apart, the card should be pulled apart.

3 The seeder is seeding, but there are no seeds in individual seed grooves. The reason is that the opener or the seed tube is blocked (mostly on the opener next to the ground wheel). The blockage should be cleared and corresponding measures should be taken to prevent debris from falling into the opener.

4 Non-stop seeding and lose control. The reason is that the separation pin of the clutch strut falls off or the separation gap is too small, and the pin should be reinstalled and locked, or the separation gap should be adjusted.

5 Seeding is intermittent and seeding is uneven. The reason is that the transmission gear meshing gap is too large, and the gear is slipping, and it should be adjusted; the clutch spring is too weak, and the gear is slippery, and the spring should be adjusted or replaced.

With the continuous development of society and economy and the in-depth application of science and technology, corn seeders have been recognized and applied by farmers. However, how should people choose corn seeders for multiple types of seeder models?

Choose according to specific planting conditions

Planting conditions include the types of corn grown, their own level of mechanical skills, and the models of existing tractors. Some varieties of corn require a single-seeder, while others require a multiple-seeder. The mechanical level refers to the ability to control and maintain the corn seeder. If a corn seeder that is too complicated is selected, it will often cause a lot of trouble during the application and maintenance process. Therefore, we should choose some corn seeders with simple structure, easy operation and control, and affordable and durable.

Shop for quality products from regular manufacturers

Optional corn seeders need full performance and high quality. This requires the purchase of large scale, high reputation and good service merchants. In the process of purchase, you must look at promoting the use license, product certification, product nameplate, and instruction manual. These documents can not only determine whether these products are qualified and regular products, but also can help farmers to use the products correctly ^[1]

After the corn seeder is purchased, it is necessary to read the instruction manual carefully so as to grasp the usage rules in quantity. If you are difficult to understand thoroughly, you can participate in the corresponding agricultural machinery technical training to truly understand the principle and master the structure, and can reach the level of operation and maintenance. After the seeder is used in quantity, the mechanical loss can be reduced, thereby increasing the service life of the machine.

Commissioning the seeder before sowing

Many parts of the planter need to be connected. In the connection process, they must be solid, the transmission parts must be flexible, and the lubrication parts must be in place. At the same time, the spacing and spacing of the seeds should be adjusted.

Determine the correctness of the seeding rate

Sowing can be divided into precise and semi-accurate quantities, which refers to single seed sowing. In the process of seeding, it is necessary to always observe whether the seeding amount is correct, the positioning is accurate, and whether each hole contains seeds. At the same time, it is necessary to observe whether the fertilizer is used accurately and uniformly. Simultaneous seeding depth and line spacing are within the specified range. If it is found to be unqualified, it needs to be stopped and readjusted to ensure the smooth seeding.

Grasp the speed and depth of seeding

The thickness of the land cover during the sowing process varies depending on the land. Generally speaking, good land needs to cover 4-5cm, and poor land needs to cover 5-6cm. The seeding speed of different seeders is different. The seeding speed of mechanical seeders is 4-6km, while the speed of pneumatic seeders is 8-10km.

Periodic inspection of the machine's opener, cover and ballast

Whether the ditcher, cover and compactor are in normal operation during seeding is directly related to the seeding situation. The ditcher and cover need to be clean and free of weeding. At the same time, the depth of the ditcher needs to be consistent. It needs to be covered evenly, so as to ensure the smooth seeding and the emergence rate. 2.5 Regular operation, timely maintenance and regular maintenance The seeder has a basic principle in the process of use, that is, prevention is greater than cure, and maintenance is more important than repair. This shows the importance of maintenance in the use of corn seeders. The maintenance of the planter mainly includes: the tightness of the bolts in important parts, the degree of defect of the bolt and the cotter pin, whether the connection part needs oiling, and the appearance needs to be repainted in time to avoid rust.
