Description

Technical Field

[0001] This invention relates to the field of peanut planting machinery technology, specifically to a multi-seed pre-filled peanut single-seed planter. Background Technology

[0002] Peanuts are a common food in our lives. They are a legume crop containing choline and lecithin, which are rare in other grains. These substances can promote metabolism, enhance memory, and are also a major source of high-quality edible oil, boasting high nutritional value. When planting peanuts, to ensure sufficient sunlight and water / fertilizer for growth, row and column spacing must be controlled, and the number of seeds sown must be strictly limited. Sowing is the most basic and crucial step in peanut production; the quality of sowing determines the overall yield. Currently, in my country's main peanut-producing areas, peanut sowing is primarily done by seeders. For any seeder, the core component is the seed metering device, which is a key factor determining the quality and performance of the machine. Whether a seeder can meet agricultural technology requirements, and to what extent, largely depends on the working condition of the seed metering device.

[0003] Based on their structural design, the seed metering devices used in peanut planters in my country can be mainly divided into two types: internally filled perforated wheel type and seed-filled wheel type. Currently, the internally filled peanut seed metering device is more commonly used. It has a simple structure and convenient transmission, and its seed filling capability allows it to adapt to high-speed operation. However, it has fewer perforated holes on the seed metering disc, and the amount of seed held in each hole cannot be precisely controlled. This makes it difficult to achieve precision sowing of ungraded seeds, resulting in problems such as uneven sowing quality, low sowing accuracy, and low operating efficiency.

[0004] In summary, the development of a high-efficiency, fast, and convenient seed metering device capable of single-seed precision planting of different peanut varieties can play a positive role in the development of peanut planting mechanization in my country. Summary of the Invention

[0005] To address the aforementioned defects and problems, this invention provides a multi-seed pre-filled peanut single-seed planter, which solves the problems of single-seed, precision planting and multiple seed varieties in existing technologies.

[0006] The solution adopted by this invention to solve its technical problem is: a multi-seed pre-filled peanut single-seed planter, including a housing, a seed metering disc, and an arc-shaped seed guard plate. One side of the housing is provided with a seed inlet and a seed loading port, and the bottom of the housing is provided with a seed feeding port and a seed metering pipe. The seed metering disc is divided into a left seed metering disc and a right seed metering disc, which can be spliced ​​together. After splicing, the large diameter section in the middle of the seed metering disc forms a V-shaped structure. The inner wall of the seed metering disc is an annular seed cleaning groove, and shaped holes are evenly distributed along the circumference of the annular seed cleaning groove. The left and right seed metering discs... The seed holes are staggered and have an inclined long groove shape. The arc-shaped seed guard plate is coaxial with the seed metering tray. The arc-shaped seed guard plate is installed inside the machine casing and is located between the left and right seed metering trays. A seed scraper is installed in the seed metering tray. The seed scraper is installed at the front end of the arc-shaped seed guard plate and can force the excess seeds outside the seed holes to be discharged. At the same time, it can make the seeds inside the seed holes lie flat. A forced seed cleaning port is opened above the seed metering tray. A forced seed cleaner is installed at the forced seed cleaning port. The forced seed cleaner can force the excess seeds in the seed holes to be removed.

[0007] A bushing is fitted through the central shaft hole of the housing. A seed metering shaft is rotatably mounted on the housing via the bushing. A seed metering shaft mounting hole is fixedly provided at the center of the seed metering disc. The seed metering disc is fixedly mounted on the seed metering shaft via the seed metering shaft mounting hole. When the seed metering shaft rotates, it can drive the seed metering disc to rotate synchronously.

[0008] Furthermore, the arc-shaped seed protection plate is divided into three parts: seed sliding, seed cleaning, and seed protection. The seed sliding part allows the seeds to slide to one side within the mold hole, the seed cleaning part removes excess seeds from the mold hole, and the seed protection part transports the seeds within the mold hole to the seed inlet.

[0009] Furthermore, the forced seed cleaner corresponds to the seed cleaning part on the arc-shaped seed protection plate, and the forced seed cleaner is provided with a seed cleaning strip that extends into the forced seed cleaning port and cooperates with the shaped hole.

[0010] Furthermore, the seed scraper has an arc-shaped structure with an inclined structure at the lower edge.

[0011] Furthermore, the housing is composed of a left housing and a right housing, and seed metering bolt mounting holes are provided on the outer edges of both sides of the left housing and the right housing. The left housing and the right housing are connected as a whole by bolts through the seed metering bolt mounting holes.

[0012] Furthermore, the seed metering device is divided into 6 zones during operation: pre-filling seed zone I, seed diversion zone II, self-cleaning seed zone III, forced seed cleaning zone IV, seed carrying zone V, and seed delivery zone VI.

[0013] Furthermore, the seed scraper is made of flexible silicone material.

[0014] The beneficial effects of this invention are as follows: The V-shaped seed metering disc and the inclined long groove holes allow the seed metering disc to be filled with two or more seeds during the filling stage, which improves the filling performance of the seed meterer. The staggered arrangement of the inclined long groove holes ensures that the number of seeds in each hole can be precisely controlled, achieving single-seed sowing and thus improving sowing accuracy. Moreover, the long groove hole structure allows for an increase in the number of holes under the condition of the same seed metering disc diameter, thereby increasing the operating speed of the seeder and improving work efficiency.

[0015] The arc-shaped seed guard plate design allows seeds to slide smoothly to the correct position within the seed hole, optimizing seed distribution in the sowing area. A flexible silicone seed scraper, in conjunction with the arc-shaped seed guard plate, removes excess seeds while minimizing physical damage, improving germination rate and growth quality. The forced seed cleaner, combined with the cleaning section of the arc-shaped seed guard plate, effectively removes excess seeds from the seed hole, ensuring precise single-seed sowing. Compared to traditional seed metering devices, this invention offers higher operating efficiency, guarantees single-seed sowing, and enables efficient, rapid, and convenient precision sowing, significantly improving sowing quality. Furthermore, its simple structure facilitates disassembly and maintenance, reducing long-term operating costs and enhancing the equipment's durability and reliability. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] Please see Figure 1-9 This invention provides a technical solution for a multi-seed pre-filled peanut single-seed seed metering device: Example

[0028] according to Figure 1 and Figure 2 As shown, the machine includes a housing 3, a seed metering tray, and an arc-shaped seed protection plate 7. The housing 3 is composed of a left housing 5 and a right housing 9. Seed metering bolt mounting holes 23 are provided on the outer edges of both sides of the left housing 5 and the right housing 9. The left housing 5 and the right housing 9 are connected as a whole by bolts through the seed metering bolt mounting holes 23. A seed inlet 24 is provided on one side of the housing 3. An upper seed inlet 2 is fixed on the outside of the seed inlet 24. A seed feeding port 26 is provided at the bottom of the housing 3. A seed metering pipe 4 is connected below the seed feeding port 26.

[0029] The specific structure of the seeding disc is as follows: Figure 3 and Figure 4 As shown, the seed metering tray is divided into a left seed metering tray 6 and a right seed metering tray 8. Bolt mounting holes 15 are provided on the opposite ends of the left seed metering tray 6 and the right seed metering tray 8, and the two are spliced ​​together by bolts. After the seed metering trays are spliced, a V-shaped structure is formed at the middle large diameter, which facilitates the filling of the seed group. The inner wall of the left seed metering tray 6 and the right seed metering tray 8 forms an annular seed cleaning groove 17. The annular seed cleaning groove 17 is evenly distributed with shaped holes 16 along the circumference, and the shaped holes 16 on the left seed metering tray 6 and the right seed metering tray 8 are staggered. Unlike the traditional internal filling seed metering tray, the shaped holes 16 of this seed metering tray adopt an inclined long groove shape structure. Under the condition that the seed metering tray diameter is the same, more shaped holes can be set on the seed metering tray, thereby improving the operation speed of the seeder. At the same time, the inclined long groove shaped holes can fill two or more seeds during the filling stage, thereby improving the filling performance of the seed meterer.

[0030] A bushing 13 is fitted through the bearing cover 11 and the bearing 10 at the central shaft hole 25 of the housing 3. Both ends of the seed metering shaft are rotatably fitted inside the bushing 13. A seed metering shaft mounting hole 18 is fixedly provided at the center of the seed metering disc. The seed metering disc is fixedly fitted on the seed metering shaft through the seed metering shaft mounting hole 18. When the seed metering shaft is controlled to rotate, it can drive the seed metering disc to rotate synchronously.

[0031] The arc-shaped seed protector 7 is coaxially designed with the seed metering tray and is fixedly installed inside the left housing 5 with bolts. After the arc-shaped seed protector 7 is installed, it is located between the left and right seed metering trays. The specific structure of the arc-shaped seed protector 7 is as follows: Figure 6 As shown, the arc-shaped seed protection plate 7 is mainly divided into three parts: seed sliding, seed cleaning and seed protection. The seed sliding part 19 allows the seeds to slide to one side in the hole 16. The seed cleaning part 20 is provided with a seed cleaning port, which can remove excess seeds in the hole 16. The seed protection part 21 can transport the seeds in the hole 16 to the seed inlet 26.

[0032] A seed scraper 12 is provided inside the seed metering tray. The seed scraper 12 is provided with bolt mounting holes 15. The seed scraper 12 is connected to the front end of the sliding part 19 of the arc-shaped seed guard plate 7 by bolts to form a whole. The seed scraper 12 has an arc-shaped structure and an inclined structure at the lower edge, which can force the excess seeds outside the hole 16 to be discharged. At the same time as removing the excess seeds outside the hole 16, it also moves the seeds inside the hole 16 to lie flat. In addition, the seed scraper 12 is made of flexible silicone material, which improves the sowing quality of the seed metering device and further reduces the damage to the seeds during forced scraping.

[0033] Before assembling the left seed tray 6 and the right seed tray 8 together, the arc-shaped seed protection plate 7 and the seed scraper 12 are installed coaxially using bolts.

[0034] A forced seed cleaning port 14 is provided above the seed metering tray, and the forced seed cleaning port 14 corresponds to the position of the seed cleaning part. A bolt mounting seat is provided in the forced seed cleaning port 14. The forced seed cleaner 1 is installed in the forced seed cleaning port 14 above the seed metering tray by bolts. The specific structure of the forced seed cleaner 1 is as follows. Figure 7 As shown, a seed cleaning strip 22 is provided on the forced seed cleaner 1. The seed cleaning strip 22 extends into the forced seed cleaning port 14 and cooperates with the mold hole 16 to remove excess seeds from the mold hole 16.

[0035] In practical use, such as Figure 9As shown, the seed metering device of the present invention is mainly divided into 6 areas during operation: pre-filling seed area I, seed guiding area II, self-cleaning seed area III, forced seed cleaning area IV, seed carrying area V, and seed dispensing area VI. Before the seed metering device starts working, seeds enter the pre-filling seed area I in a limited quantity through the seed inlet 24. When the seed metering device starts working, the machine's traveling wheels transmit power to the seed metering shaft through a chain, universal joint, or other transmission device. The seed metering disc rotates synchronously with the seed metering shaft. When the seed metering disc passes over the seed group, the seeds are separated under the stirring action of the rotating seed metering disc, forming a circumferential seed layer with different speeds. Under the combined action of the seeds' own gravity, the inter-group force, and the rotation of the seed metering disc, the seeds are filled into the seed metering holes 16, completing the seed filling process.

[0036] When the seed-carrying hole 16 leaves the pre-filling seed area I and enters the seed guiding area II, under the action of the arc-shaped seed protection plate 7, the seeds in the seed-carrying hole 16 gradually slide from the large diameter of the seed discharge plate to the small diameter under the combined action of their own gravity and centrifugal force, thus completing the seed guiding process.

[0037] As the seed metering disc continues to rotate, the seed-carrying hole 16 moves to the top of the seed metering disc, and the seeds enter the self-cleaning seed area III. Due to the change in the direction of the force system, the excess seeds in the hole 16 that are far away from the small diameter of the seed metering disc slide down into the pre-filling seed area I under the action of gravity, so that only one seed is left in the hole 16, thus completing the self-cleaning seed process of the seed meterer.

[0038] When the seed-carrying hole 16 leaves the self-cleaning area Ⅲ and enters the forced seed-cleaning area Ⅳ, if there are still excess seeds in the hole 16, the excess seeds will be removed under the action of the forced seed cleaner 1, thus completing the forced seed-cleaning process;

[0039] As the seed metering disc continues to rotate, the seeds enter the seed-carrying area V. Under the protection of the arc-shaped seed-protecting plate 7, the seed-carrying holes 16 complete the seed-carrying process as the seed metering disc rotates. Finally, the seeds rotate to the seeding area VI. At the seeding port 26, under the action of gravity and centrifugal force, the seeds detach from the seed metering disc holes 16 and enter the seed metering tube 4, thus falling into the seed bed, completing the seeding and realizing precision sowing operations. Example

[0040] Based on Embodiment 1, the seed cleaning strip 22 on the forced seed cleaner 1 can be a soft seed scraping brush. The soft seed scraping brush can force excess seeds out of the hole 16. When the seed scraping brush comes into contact with the seeds, it can reduce physical damage to the seeds, thereby improving the quality of sowing.

[0041] The above description is only a preferred embodiment of the present invention and does not limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
