Description

Technical Field

[0001] The invention relates to the technical field of peanut sowing machinery, in particular to a multi-grain pre-filled peanut single-grain sowing seed meter. Background Art

[0002] Peanuts are a very common thing in our lives. They are a leguminous crop that contains choline and lecithin, which are rare in general grains. They can promote human metabolism and enhance memory. Peanuts are also one of the main oil varieties of high-quality edible oils, and their nutritional value is also very high. When sowing peanuts, in order to ensure the needs of light and water and fertilizer for growth, it is necessary to control the row spacing and column spacing, and the number of peanut seeds sown must be strictly controlled. In the process of peanut planting, sowing operations are the most basic and important link in the entire peanut production process. The sowing quality determines the yield of the entire process. At present, peanut sowing operations in my country's main peanut producing areas are generally completed by seeders. For any kind of seeder, the core is the seeding device, which is an important factor in determining the work quality and performance of the seeder. Whether the seeder can meet the requirements of agricultural technology or the degree of satisfaction depends largely on the working condition of the seeding device.

[0003] According to different structural types, the seeders used in my country's peanut planters can be mainly divided into two types: internal filling hole wheel type and socket wheel type. At present, the most commonly used is the internal filling peanut seeder, which has a simple structure and convenient transmission. It can adapt to high-speed operation in terms of seed filling, but there are fewer holes on the seeding disc, and the amount of seeds kept in each hole cannot be accurately controlled, making it difficult to achieve precise sowing of ungraded seeds. There are problems such as uneven sowing quality, low sowing operation accuracy, and low operation efficiency.

[0004] In summary, the development of an efficient, fast, convenient, and single-grain precision sowing and metering device for different varieties of peanut seeds can play a certain positive role in the development of peanut sowing mechanization in my country. Summary of the invention

[0005] In view of the above-mentioned defects and problems, the present invention provides a multi-grain pre-filled peanut single-grain sowing and metering device, which solves the problems of single peanut grain, precision sowing and a large number of seed varieties in the prior art.

[0006] The solution adopted by the present invention to solve its technical problem is: a multi-grain pre-filled peanut single-grain sowing seed meter, including a casing, a seeding tray and an arc-shaped seed protection plate, one side of the casing is provided with a seed inlet and an upper seeding port, a seeding port and a seeding tube are provided below the casing, the seeding tray is divided into a left seeding tray and a right seeding tray, and the two can be spliced ​​into one body, and a V-shaped structure is formed at the middle large diameter of the seeding tray after splicing, the inner wall of the seeding tray is an annular seed cleaning groove, and the annular seed cleaning groove is evenly provided with shaped holes along the circumferential direction, and the left seeding tray and the right seeding tray are provided with holes. The shaped holes are arranged in a staggered manner, and the shaped holes adopt an inclined long groove shape structure. The arc-shaped seed protection plate is designed to be coaxial with the seeding disc, and the arc-shaped seed protection plate is installed inside the casing and is located between the left and right seeding discs. A seed scraper is arranged inside the seeding disc, and the seed scraper is installed at the front end of the arc-shaped seed protection plate. It can forcibly discharge excess seeds outside the shaped holes and at the same time move the seeds in the shaped holes to lie flat. A forced seed cleaning port is opened above the seeding disc, and a forced seed cleaner is installed at the forced seed cleaning port. The forced seed cleaner can forcibly clean out excess seeds in the shaped holes; A shaft sleeve is inserted through the central shaft hole of the casing, a seeding shaft is rotatably mounted on the casing through the shaft sleeve, a seeding shaft mounting hole is fixedly provided at the center of the seeding disk, the seeding disk is fixedly mounted on the seeding shaft through the seeding shaft mounting hole, and when the seeding shaft rotates, the seeding disk can be driven to rotate synchronously.

[0007] Furthermore, the arc-shaped seed protection plate is divided into three parts: seed sliding, seed cleaning and seed protection. The seed sliding part can make the seeds slide to one side in the mold hole, the seed cleaning part can clear out the excess seeds in the mold hole, and the seed protection part can transport the seeds in the mold hole to the seed dropping port.

[0008] Furthermore, the forced seed cleaner corresponds to the seed cleaning position on the arc-shaped seed protection plate, and a seed cleaning strip is arranged on the forced seed cleaner, which extends into the forced seed cleaning port and matches with the mold hole.

[0009] Furthermore, the seed scraper plate is an arc-shaped structure, and the lower edge is an inclined structure.

[0010] Furthermore, the casing is composed of a left shell and a right shell, and the outer edges of both sides of the left shell and the right shell are provided with seed meter bolt mounting holes, and the left shell and the right shell are connected into a whole through the seed meter bolt mounting holes and bolts.

[0011] Furthermore, the seed meter is divided into 6 areas during operation: pre-seeding area I, seed diversion area II, self-seeding area III, forced seed cleaning area IV, seed carrying area V, and seed dropping area VI.

[0012] Furthermore, the scraper plate is made of flexible silicone material.

[0013] The beneficial effects of the present invention are as follows: the seeding disc with a V-shaped structure and the inclined long slot-shaped holes enable the seeding disc to be filled with two or more seeds during the seed filling stage, thereby improving the seed filling performance of the seeding device; the staggered arrangement of the inclined long slot-shaped hole design ensures that the number of seeds in each hole can be accurately controlled to achieve single seed sowing, thereby improving the sowing accuracy; and the holes with the long slot-shaped structure allow the number of holes to be increased under the condition that the diameter of the seeding disc is the same, thereby increasing the operating speed of the seeder and improving the work efficiency; The design of the arc-shaped seed protection plate enables the seeds to slide smoothly to the correct position in the mold hole, optimizes the distribution of seeds in the sowing area, and adopts a seed scraper plate made of flexible silicone material in combination with the arc-shaped seed protection plate to reduce physical damage to the seeds while removing excess seeds, thereby improving the germination rate and growth quality of the seeds. The forced seed cleaner is combined with the seed cleaning part of the arc-shaped seed protection plate to effectively remove excess seeds in the mold hole and ensure the accuracy of single-grain sowing. Compared with traditional seed meters, the seed metering device of the present invention has high operating efficiency, can ensure single-grain sowing, can realize efficient, fast and convenient precision sowing operations, and significantly improves the sowing quality. It also has a simple structure and is easy to disassemble and maintain, which reduces long-term operating costs and improves the durability and reliability of the equipment.

DETAILED DESCRIPTION

[0016] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0017] See also Figure 1-9 The present invention provides a technical solution for a multi-grain pre-filled peanut single-grain sowing and metering device: Example

[0018] according to Figure 1 and Figure 2 As shown, it includes a casing 3, a seeding disc and an arc-shaped seed protection plate 7. The casing 3 is composed of a left casing 5 and a right casing 9. The outer edges of both sides of the left casing 5 and the right casing 9 are provided with seeding device bolt mounting holes 23. The left casing 5 and the right casing 9 are connected into a whole through the seeding device bolt mounting holes 23 and bolts. A seed inlet 24 is provided on one side of the casing 3, and an upper seeding port 2 is fixed on the outer side of the seed inlet 24. A seed dropping port 26 is provided below the casing 3, and a seeding tube 4 is connected below the seed dropping port 26.

[0019] The specific structure of the seed tray is as follows: Figure 3 and Figure 4 As shown, the seeding disc is divided into a left seeding disc 6 and a right seeding disc 8, and bolt mounting holes 15 are correspondingly arranged on the opposite end surfaces of the left seeding disc 6 and the right seeding disc 8, and the two are spliced ​​into one body by bolts. After the seeding discs are spliced, a V-shaped structure is formed at the middle large diameter, which is convenient for filling the seed group. The inner walls of the left seeding disc 6 and the right seeding disc 8 form an annular seed cleaning groove 17, and the annular seed cleaning groove 17 is evenly distributed with shaped holes 16 along the circumferential direction. The shaped holes 16 on the left seeding disc 6 and the right seeding disc 8 are staggered. Different from the traditional inner seed filling type seeding disc, the shaped holes 16 of the seeding disc adopt an inclined long groove shape structure. Under the condition that the diameter of the seeding disc is the same, more shaped holes can be arranged on the seeding disc, thereby improving the operating speed of the seeder; at the same time, the inclined long groove shaped holes can be filled with two or more seeds during the filling stage, thereby improving the filling performance of the seeder.

[0020] A shaft sleeve 13 is inserted through the bearing cover 11 and the bearing 10 at the center shaft hole 25 of the casing 3. Both ends of the seeding shaft are rotatably inserted into the shaft sleeve 13. A seeding shaft mounting hole 18 is fixedly provided at the center of the seeding disk. The seeding disk is fixedly mounted on the seeding shaft through the seeding shaft mounting hole 18. When the seeding shaft is controlled to rotate, the seeding disk can be driven to rotate synchronously.

[0021] The arc seed protection plate 7 is designed to be coaxial with the seeding disc and is fixed to the inner side of the left housing 5 by bolts. When the arc seed protection plate 7 is installed, it is located between the left and right seeding discs. The specific structure of the arc seed protection plate 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 shaped hole 16, the seed cleaning part 20 is provided with a seed cleaning port, which can clear out the excess seeds in the shaped hole 16, and the seed protection part 21 can transport the seeds in the shaped hole 16 to the seed dropping port 26.

[0022] A scraper plate 12 is arranged in the seed plate, and a bolt mounting hole 15 is arranged on the scraper plate 12. The scraper plate 12 is connected to the front end of the sliding part 19 of the arc-shaped seed protection plate 7 by bolts to form a whole. The scraper plate 12 is an arc-shaped structure, and the lower edge is an inclined structure. It can force the excess seeds outside the shaped hole 16 to be discharged, and at the same time, the excess seeds outside the shaped hole 16 are cleared and the seeds in the shaped hole 16 are moved to lie flat. The scraper plate 12 is made of flexible silicone material, which improves the sowing quality of the seed meter and further reduces the damage to the seeds during forced scraping.

[0023] Before the left seeding disc 6 and the right seeding disc 8 are assembled together, the arc seed protection plate 7 and the seed scraping plate 12 are coaxially installed by bolts.

[0024] A forced seed cleaning port 14 is provided above the seeding plate, and the forced seed cleaning port 14 corresponds to the position of the seed cleaning part. A bolt mounting seat is provided at the forced seed cleaning port 14. The forced seed cleaning device 1 is installed at the forced seed cleaning port 14 above the seeding plate by bolts. The specific structure of the forced seed cleaning device 1 is as follows: Figure 7 As shown, a seed cleaning strip 22 is provided on the forced seed cleaning device 1. The seed cleaning strip 22 extends into the forced seed cleaning port 14 and cooperates with the shaped hole 16 to clean out the excess seeds in the shaped hole 16.

[0025] When used specifically, Fig. 9As shown, the seeding device of the present invention is mainly divided into 6 areas during operation: pre-seed filling area I, seed diversion area II, self-seed cleaning area III, forced seed cleaning area IV, seed carrying area V, and seed dropping area VI. Before the seeding device works, seeds enter the pre-seed filling area I in a limited amount through the seed inlet 24. When the seeding device works, the running wheel of the machine transmits power to the seeding shaft through a chain, a universal shaft or other transmission device, and the seeding disk rotates synchronously with the seeding shaft. When the shaped holes 16 on the seeding disk pass through the seed group, the seeds are separated under the action of the rotation and stirring of the seeding disk, forming a circumferential seed layer with different speeds. Under the combined action of the seed's own gravity, the force between the groups and the rotation of the seeding disk, the seeds are filled into the shaped holes 16 to complete the seed filling process; When the shaped hole 16 carries the seeds out of the pre-filling area I and enters the seed diversion area II, under the action of the arc-shaped seed protection plate 7, the seeds in the shaped hole 16 gradually slide from the large diameter of the seed plate to the small diameter under the combined action of their own gravity and centrifugal force, completing the seed diversion process; As the seeding disc continues to rotate, the seed-carrying hole 16 moves to the top of the seeding disc, and the seeds enter the self-cleaning 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 seeding disc slide down to the pre-filling area I under the action of gravity, so that only one seed is retained in the hole 16, completing the self-cleaning process of the seeding device; When the seed-carrying hole 16 leaves the self-clearing area III and enters the forced seed-clearing area IV, if there are still excess seeds in the hole 16, the excess seeds are cleared out by the forced seed-clearing device 1, completing the forced seed-clearing process; As the seed disc continues to rotate, the seeds enter the seed carrying area V. Under the protection of the arc-shaped seed protection plate 7, the seed carrying holes 16 rotate with the seed disc to carry the seeds. Finally, the seeds rotate to the seeding area VI. At the seeding port 26, the seeds, under the action of gravity and centrifugal force, separate from the seed disc holes 16 and enter the seeding tube 4, thereby falling into the seed bed, completing the seeding and realizing precision seeding operations. Example

[0026] On the basis of the first embodiment, the seed cleaning strip 22 on the forced seed cleaner 1 can adopt a soft seed scraping brush, through which the excess seeds are forcibly scraped out of the mold hole 16. When the seed scraping brush contacts the seeds, it can reduce the physical damage to the seeds, thereby improving the quality of sowing.

[0027] 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 principle of the present invention should be included in the protection scope of the present invention.
