Description

Technical Field

[0001] This utility model relates to the field of corn planter technology, and in particular to a seed corn planter with adjustable planting density. Background Technology

[0002] A corn planter is an agricultural machinery device used for planting corn. In terms of precision planting, it can control the planting depth and accurately control the plant and row spacing. In terms of improving planting efficiency, it can quickly plant and adapt to the needs of large-scale planting. In terms of improving planting quality, it can evenly distribute seeds and provide good soil coverage and compaction. With the continuous advancement of technology, seed corn planters are gradually becoming more accessible to the general public.

[0003] A seed corn planter is an agricultural machine specifically designed for corn seed production. Its main function is to precisely sow parent corn seeds into the field according to specific requirements. During the corn seed production process, it is necessary to strictly control the sowing of parent seeds to ensure the quality and yield of hybrid seeds. However, since the same device can only have one sowing density, it cannot change the density when dealing with multiple types of seeds. In the existing technology, seed corn planters with adjustable sowing densities are gradually being widely used. However, in order to ensure the stability of sowing accuracy and density, the quality requirements for seed shape, size, and uniformity are more stringent. If the seed quality is inconsistent, problems such as poor seed distribution, missed sowing, and double sowing will occur, thus affecting the sowing effect. Therefore, manual seed selection is required, which reduces work efficiency and wastes human resources. Utility Model Content

The seeds can be separated into different types. The top center of the storage box 5 is connected to the input pipe 12. The bottom of the storage box 5 is equipped with a conveyor box 8. The bottom inner side of the storage box 5 is equipped with a pushing mechanism 2, which is used to convey corn seeds. The bottom right side of the storage box 5 is fixedly connected to a support plate 17. The bottom front and rear ends of the support plate 17 are fixedly connected to support rods 16. The top of the input pipe 12 is equipped with a round cover 11. The top of the round cover 11 is fixedly connected to a short fixing post 3. The installation of the round cover 11 prevents dirt from entering the inside. The top left and right ends of the storage box 5 are equipped with first handles 4. The front and rear sides of the first handles 4 are threaded with screws 13. The installation of the first handles 4 makes it easy to open the storage box 5.

[0032] Reference Figure 1 , Figure 3 and Figure 5 The pushing mechanism 2 includes a first motor 201, which is installed at the bottom left side of the storage box 5. The output end of the first motor 201 is fixedly connected to a pulley 204, and the top of the pulley 204 is fixedly connected to a connecting rope 203. Through the installation of the first motor 201, the connecting rope 203 can be wound around the outside of the pulley 204. The right end of the connecting rope 203 passes through the left side of the storage box 5 and is fixedly connected to a sliding plate 206. The front and rear ends of the left side of the sliding plate 206 are fixedly connected to springs 202, and telescopic tubes 205 are installed on the outside of the springs 202. A fixed plate 6 is provided at the bottom of the pushing mechanism 2, and a connecting plate 7 is fixedly connected to the bottom of the fixed plate 6. The right side of the connecting plate 7 is fixedly connected to the left side of the storage box 5. Through the installation of the connecting plate 7, the first motor 201 is supported. The first motor 201 and the second motor 18 are both M3508.

[0033] Reference Figure 1 , Figure 2 and Figure 3Multiple connecting mechanisms 9 are equidistantly installed on the front side of the body 1. A tire 10 is provided in the middle of the connecting mechanism 9. The installation of the tire 10 facilitates the movement of the device. A top cover 19 is rotatably connected to the top rear side of the body 1. A rotating shaft 15 is rotatably connected to the rear side of the top cover 19. A second handle 14 is installed on the front top of the top of the top cover 19. The installation of the second handle 14 facilitates the opening of the top cover 19.

[0034] Working principle: When machine sowing is required, first pour the seeds into the input pipe 12, then turn on the second motor 18, so that the rotating rod 22 starts to rotate, and then the multiple stirring blades 23 rotate synchronously. At this time, the rotating disc 24 also starts to rotate, and stirs with multiple stirring rods 21 to avoid the seeds not being stirred at the bottom. Through the installation of the filter plate 20, smaller unsuitable seeds are filtered out. The filtered seeds will be removed, and the remaining seeds will continue to be used. Through the installation of the conveying box 8, the density of the sowing is controllable. Through the conveying of the storage box 5, the seeds input into (8) are controllable. When the device is not needed, the round cover 11 is placed on the top of the input pipe 12 by fixing the short column 3 to prevent dirt from entering. Through the above process, the device can screen unsuitable seeds, thereby improving work efficiency.

[0035] First, smaller seeds are removed. Then, the filter plate 20 is removed, and suitable seeds fall to the bottom of the inner side of the storage box 5. Next, the first motor 201 is turned on, causing the pulley 204 to start rotating. This causes the connecting rope 203 to be wound around the outer wall of the pulley 204, which pulls the sliding plate 206 to slide to the left, thus pushing the seeds gradually into the interior of multiple conveying boxes 8 for sowing. When the number of seeds decreases, the first motor 201 is adjusted to rotate in the opposite direction, causing the spring 202 to rebound. The sliding plate 206 then moves to the right and pushes the seeds into the conveying box 8 again. Through the above process, the seeds can be evenly and gradually put into the conveying box 8, thereby improving work efficiency.

[0036] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
