Description

Technical Field

[0001] The invention relates to the technical field of seeders, in particular to a multi-hole seeder with adjustable sowing distance. Background Art

[0002] In the field of agricultural planting, the seeder is a new type of agricultural machinery that aims to replace traditional manual operations to improve planting efficiency and quality. It is suitable for a variety of crops and seeds and can complete the sowing of a single crop at one time, thereby achieving the effect of saving costs and improving moisture conservation. In summary, the inventors have found that the existing seeders mainly have the following defects: since the current seeder can only collect and stably sow seeds of one type of crop, two seeders are required to plant two different crop seeds, which will cause mutual influence between the two seeders and reduce the sowing efficiency and fail to meet the characteristics of multi-hole sowing. At the same time, the spacing between the current seeders is fixed, so it is very easy to cause difficulty in matching the sowing trough position of the field during sowing, thereby reducing the sowing accuracy. Furthermore, there is a difference between the diameter of the sowing trough of the current seeder and the size of the crop seeds, which makes it impossible to adjust its own diameter according to the size of the crop planting, so it is impossible to achieve the effect of controlling the sowing amount, which will cause the defect of too much or too little sowing in a single sowing trough. Summary of the invention

[0003] The technical solution adopted by the present invention to achieve the technical purpose is: a multi-hole seeder with adjustable sowing spacing, whose structure includes: a controller, a vertical column, a main unit, a moving wheel, and a new sowing structure.

During the process, the spacing of the vertical sowing bodies is adjusted by the lateral adjustment rod, and the parallel plates of the vertical sowing bodies can be adjusted again through the slide rail to adjust the position of the aperture adjuster to match the planting trough position of the field. Finally, the aperture adjuster determines the sowing amount of crop seeds by adjusting the size of the sowing hole.

[0009] As a further improvement of the present invention, the sowing hole adjustment body is provided with a limiting block, which passes through the edge of the limiting ring and is the same as the discharge hole in the center of the limiting ring. The rear end of the limiting block is fixedly connected to the assembly part and is connected to the electric block through the assembly part. The electric block is embedded in the linear rail and drives the limiting block to slide parallel in the linear rail.

[0010] As a further improvement of the present invention, the discharge hole is circular and hollow in shape, and each of the four ends of the edge carries a linear rail to form a "cross" arrangement. Each linear rail is equipped with an electric block, an assembly part, and a limiting block. The limiting block is an arc-shaped solid shape and the surface is finely polished.

[0011] As a further improvement of the present invention, the controller is provided with a touch screen, which is embedded in the center of the surface edge of the force-bearing block. The edge of the force-bearing block is provided with a rotating control body. The rotating control body is combined with the force-bearing block to complete the electrical connection with the touch screen and the host and electrically control the moving wheel. At the same time, the touch screen electrically controls the new sowing structure through the host. Power-on blocks are installed on the left and right sides of the force-bearing block, and a metal block is connected to the bottom of the power-on block, so that the power-on block can carry the metal block and be embedded in the vertical column to complete the electrical connection with the host.

[0013] As a further improvement of the present invention, the rotating control body is provided with an insert block, which is arranged on the left and right sides of the circuit box and is electrically connected to the circuit box through a power block. The outer layer of the circuit box is covered with an anti-slip cover, and the forward control key, the backward control key, and the stop control key all pass through the edge of the anti-slip cover to complete the electrical connection with the circuit box and control the moving wheel through the insert block, the power block, and the main unit.

[0014] As a further improvement of the present invention, the vertical columns are provided on both sides of the upper end of the mainframe and are fixedly electrically connected to the controller, and the center area of ​​the moving wheel at the edge of the mainframe is equipped with a fixed-point rotating rod.

[0015] As a further improvement of the present invention, the loading piece is circular in shape and carries a threaded cover plate on the top, and the positioning block at the lower end of the collecting box is a rectangular solid shape, and then the three groups of vertical seeding bodies in the guide tube area can be adjusted in spacing through a lateral adjustment rod.

[0016] As a further improvement of the present invention, the slide rail of the parallel plate is opened in a straight line and carries multiple sets of aperture adjusters. The branch pipe is in a rectangular shape and is equipped with a storage cavity for crop seeds. Then, the connecting end is combined to allow the crop seeds to fall stably into the aperture adjuster.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention is based on three sets of new sowing structures arranged at the front end of the main machine, which can collect three or two different crop seeds in a collection box, and then distribute them to the vertical sowing body through the guide tube of the collection box, so that the vertical sowing body can adjust its own spacing through the horizontal adjustment rod during sowing, so as to meet the sowing spacing of the field and ensure the sowing spacing effect of different crops. Then, the branch pipe of the vertical sowing body can be combined with the slide rail of the bottom parallel plate to change the position of the aperture adjuster, so that the aperture adjuster can be accurately aligned with the planting groove, thereby improving the accuracy of the crop seeds entering the planting groove, and then the spacing accuracy between each crop seed can be improved.

[0018] 2. The present invention is further improved by the aperture adjuster. The "I" shape formed by the balancing block, the vertical tube, and the sowing hole adjusting body can improve the parallel stability in the slide rail. At the same time, the sowing hole adjusting body can allow the electric block to drive the arc-shaped limiting block to slide through the assembly according to its own "X" linear rail, so that the limiting block can pass through the edge of the limiting ring and enter the through groove area. Therefore, the through groove can change its own aperture effect after being blocked by the limiting block, so that the sowing quantity of crop seeds and the effect of different crop seed sizes can be determined according to the change of the aperture, avoiding excessive or insufficient discharge and affecting the normal sowing stability.

[0019] 3. After the controller of the present invention is further improved, the power blocks and metal blocks on the left and right sides of the force-bearing block can improve the electrical control effect of the touch screen and the rotating control body on the new sowing structure and the moving wheel, so that the touch coordination of the touch screen can improve the convenience of controlling the sowing spacing and sowing aperture size adjustment of the new sowing structure, and then the rotating control body can accurately control the movement of the moving wheel according to the coordination of its own forward control key, backward control key and stop control key, thereby improving the alignment and matching of the overall seeder with the planting area position of the field and improving the convenience of movement in the field.
