Description

Technical Field

[0001] The invention relates to the technical field of garlic sowing, and in particular to an elastic opening and closing type single garlic seed taking device. Background Art

[0002] Garlic is an important and common cash crop with a unique flavor and high nutritional value. To ensure a high germination rate and excellent growth quality, garlic sowing requires "single seed, root below, bud above, and upright planting." Traditionally, manual sowing has been the primary method in China. This labor-intensive, inefficient, and costly method no longer meets the requirements of modern agricultural development. Therefore, mechanized garlic sowing is an important alternative to manual labor.

[0003] A crucial step in mechanized garlic sowing is the ability to extract individual seeds. The chain-type scoop, one of the primary seed extraction methods for garlic sowing machines, operates by driving a chain-driven seed scoop through a seed box to extract garlic. However, the typical chain-type scoop is slightly larger than a single garlic seed, which can lead to the extraction of two garlic seeds, resulting in duplicate seeds. Furthermore, during the seeding process, vibrations from the machine and the chain can cause garlic seeds to fall, resulting in missed seeds, reduced sowing efficiency, and diminished garlic yields. Therefore, a device capable of precisely extracting individual garlic seeds is urgently needed. Summary of the Invention

[0004] The purpose of the present invention is to solve the above technical problems and provide an elastic opening and closing single-grain garlic seeding device, which can reduce the garlic sowing re-seeding rate and seed missing rate and realize the precise single-grain garlic seeding.

[0005] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0006] Disclosed is an elastic opening and closing type single-grain garlic seed-taking device, comprising a transmission shaft, a sprocket, a chain with ears, a seed box, and an elastic opening and closing type seed-taking spoon. The seed box has an opening at the top and an opening at the bottom that is only capable of passing the chain and the elastic opening and closing type seed-taking spoon. The transmission shaft, sprocket, and chain with ears are powered by a power device. The elastic opening and closing type seed-taking spoon is equidistantly mounted on the chain with ears. The chain with ears and the elastic opening and closing type seed-taking spoon pass through the seed box from bottom to top. A seed-taking spoon opening device is mounted on the inner wall of the seed box on a side close to the chain with ears. The seed-taking spoon opening device cooperates with the elastic opening and closing type seed-taking spoon to achieve single-grain garlic seed-taking.

[0007] Preferably, the seed box is fixed to the frame by bolts and nuts, and the fixed side seed box wall is provided with round holes and straight slots for fixing the seed box and installing the seed spoon opening device. The ear plates around the bottom of the seed box are connected to the ear plates of the rectangular channel below by bolts and nuts.

[0008] Preferably, the elastic opening and closing seed taking spoon includes a seed taking spoon body and two opening and closing side walls, the seed taking spoon body is provided with a seed blocking plate at the top end close to the ear chain, and three connecting plates are provided on the back side, and a hemispherical groove is provided at the bottom inside the seed taking spoon body.

[0009] Preferably, the connecting plate and the ear plate of the ear chain are connected by bolts and nuts, and the seed taking spoon body and the opening and closing side walls on both sides are connected by cotter pins and two torsion springs.

[0010] Preferably, slender strip-shaped torsion spring limiting grooves are provided on the side surface of the seed taking spoon body and the outer side of the opening and closing side wall.

[0011] Preferably, the seed spoon opening device consists of a stop rod, a limit rod, a limit bolt and a nut. The limit bolt is fixed to the frame through the stop rod, the limit nut, the flange nut and the straight slot on the rear wall of the seed box. Loosening the flange nut can move the bolt left and right so that the stop rod can adapt to the elastic opening and closing seed spoons of different sizes and control the opening time of the opening and closing side walls of the seed spoon. The limit rod is fixed below the straight slot, and the stop rod rotates within a range between the limit rod and the limit bolt.

[0012] Preferably, the seed taking spoon opening device is arranged on both sides of the elastic opening and closing seed taking spoon and is staggered in an upper and lower position.

[0013] The present invention has the following technical effects: a chain with ears drives an elastic opening and closing seed scoop to perform a circular motion within a seed box, where garlic seeds are placed. The elastic opening and closing seed scoop scoops up multiple garlic seeds as it passes through the seed box. After scooping up the garlic seeds, the elastic opening and closing seed scoop continues to move upward along with the chain. When passing through the seed scoop opening device, the two opening and closing side walls of the elastic opening and closing seed scoop open sequentially and compress the torsion spring. After passing through the opening device, the opening and closing side walls, under the elastic force of the torsion spring, sequentially eject the excess garlic seeds on both sides of the hemispherical groove, leaving only one garlic seed in the hemispherical groove, reducing the rate of duplicate and missed seeds and enabling single-seed retrieval. Loosening the limit bolt to adjust the position of the seed scoop opening device can control the opening position and opening time of the opening and closing side walls to enable single-seed retrieval of garlic seeds of different particle sizes. The present invention adopts the principle of taking more than one and leaving one behind, first taking two or more seeds to ensure that no seeds are missed, and then the elastic opening and closing side walls remove the excess seeds to prevent duplicate seeding.

[0021] like Figure 1-6 As shown, the device of the present invention includes a transmission shaft 7, a sprocket 5, a chain with ears 6, a seed box 3, and an elastic opening and closing seed taking spoon 1. The seed box 3 is open at the top and has an opening 11 at the bottom that can only pass through the chain and the elastic opening and closing seed taking spoon. The transmission shaft 7, sprocket 5, and chain with ears 6 are powered by a power device. The elastic opening and closing seed taking spoon 1 is installed on the chain with ears 6 at equal intervals. The chain with ears 6 and the elastic opening and closing seed taking spoon 1 pass through the seed box 3 from bottom to top. A seed taking spoon opening device 2 is installed on the inner wall of the seed box 3 close to the chain with ears 6. The seed taking spoon opening device 2 cooperates with the elastic opening and closing seed taking spoon 1 to realize single-grain garlic seed taking.

[0022] Specifically, the seed box 3 is fixed to the frame by bolts and nuts, and a circular hole 12 and a straight slot 8 are opened on the fixed side seed box wall, which are respectively used for fixing the seed box 3 and installing the seed spoon opening device 2. The fixed side seed box wall is also provided with a limit rod 9, which is used to limit the middle lever 27 of the opening device. The ear plates 10 around the bottom of the seed box 3 are connected to the ear plates of the rectangular channel 4 below by bolts and nuts.

[0023] Specifically, the elastic opening and closing seed spoon 1 mainly includes a seed spoon body 18 and two opening and closing side walls 21. The seed spoon body 18 and the opening and closing side walls 21 are connected to two torsion springs 16 through an opening pin 19. The opening pin 19 passes through the holes of the seed spoon body 18, the opening and closing side walls 21, and the torsion spring 16 to realize the connection.

[0024] Specifically, a rectangular seed-blocking plate 22 is provided on the top of the seed-taking spoon body 18 near the side of the ear chain 6 to prevent the garlic seeds from falling during the sowing stage after the seed-taking spoon is placed flat. Three connecting plates 13 are provided on the back side, and each connecting plate 13 has two circular holes. The connecting plates 13 are connected to the ear plates 14 of the ear chain 6 by bolts and nuts 15.

[0025] Specifically, a hemispherical groove 20 is opened at the lower part of the seed-taking spoon body 18 to keep the garlic seeds in the spoon in a stable state after cleaning. A slender strip-shaped torsion spring limiting groove 17 is opened on the side of the seed-taking spoon body 18 and the outer side of the opening and closing side wall 21 to limit the torsion spring 16 from moving left and right.

[0026] Specifically, the seed spoon opening device 2 is composed of a stop rod 27, a limiting rod 9, a limiting nut 26, and a limiting bolt 28. The limiting bolt 28 passes through the stop rod 27, the limiting nut 26, the flange nut 25 and the straight slot 8 on the rear wall of the seed box 3 and is fixed to the frame. Loosening the flange nut 25 can allow the limiting bolt 28 to move left and right in the straight slot so that the stop rod 27 can reach and open the opening and closing side walls 21 of seed spoons of different sizes. Therefore, the seed spoon opening device 2 can adapt to the elastic opening and closing seed spoons 1 of different sizes and control the opening time of the opening and closing side walls of the seed spoon. The limiting rod 9 is fixed below the straight slot 8, and the stop rod 27 rotates between the limiting rod 9 and the limiting bolt 28.

[0027] Specifically, the seed spoon opening device 2 is arranged on both sides of the elastic opening and closing seed spoon 1 and is staggered in an upper and lower position to enable the opening and closing side walls 21 on both sides to open in sequence, preventing the garlic seeds removed from both sides from being bounced together and colliding when opening at the same time and then falling back into the seed spoon.

[0028] When the present invention is in use, the transmission shaft 7, the sprocket 5, and the ear chain 6 are driven by the power device to drive the elastic opening and closing type seed taking spoon 1 to pass through the seed box 3 and take out multiple garlic grains from the garlic seed pile. When the blocking rod 27 is not in contact with the elastic opening and closing type seed taking spoon 1, the blocking rod 27 is stationary on the limiting rod 9. As the elastic opening and closing type seed taking spoon 1 moves upward, the blocking rod 27 contacts and hooks with the opening and closing side wall 21 on one side, and the elastic opening and closing type seed taking spoon 1 continues to move upward, and the blocking rod 27 rotates accordingly until the blocking rod 27 contacts the limiting bolt 28. At this time, the blocking rod 27 does not move, and the elastic opening and closing type seed taking spoon 1 continues to move upward, and the opening and closing side wall 21 opens under the action of the baffle 27, and some garlic seeds fall down. The opening and closing side wall 21 is separated from the baffle 27 after opening to the maximum angle. During the opening process of the opening and closing side wall 21, the excess garlic seeds on the same side can fall down under the action of gravity. Afterwards, the opening and closing side wall 21 is reset under the elastic action of the torsion spring 16. During the reset, the opening and closing side wall 21 ejects the excess garlic seeds that have not fallen down in time, and the elastic opening and closing seed taking spoon 1 continues to move upward. The opening and closing side wall 21 on the other side contacts the baffle 27 on the other side, and the above process is repeated. Finally, only one garlic seed is left in the hemispherical groove 20 of the elastic opening and closing seed taking spoon 1, realizing the single garlic seed taking.

[0029] In summary, the present invention provides an elastic opening and closing type single garlic seed removing device. To solve the problems of high seed missing rate and repeated planting rate in the existing spoon chain type seed removing device, the elastic opening and closing type seed removing spoon has an openable side wall structure for seed cleaning, ensuring that there is only one garlic seed in the seed removing spoon after the seed cleaning process is completed, realizing single garlic seed removal, reducing seed missing and repeated planting rates, and improving the efficiency of single garlic seed removal. The device has extremely high application and promotion value and market prospects.
