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 economic crop with unique flavor and high nutritional value. In order to ensure high germination rate and excellent growth quality of garlic, it is required to sow "single seed, root below bud above, and upright planting". China has always mainly sowed garlic manually, which has high labor intensity, low work efficiency and high labor cost, and can no longer meet the requirements of modern agricultural development. Therefore, mechanization for garlic sowing is an important means to replace manual labor.

[0003] The most important step in mechanized garlic sowing is to be able to achieve single seed extraction. The spoon chain type is one of the main seed extraction methods of garlic sowing machinery. Its working principle is that the transmission chain drives the seed extraction spoon on the chain to take out the garlic after passing through the seed box. The size of the classic spoon chain type seed extraction spoon is slightly larger than a garlic seed. During the seed extraction process, two garlic seeds may be taken, resulting in double planting. During the seed delivery process, due to the vibration of the machine and the shaking of the chain, the garlic seeds fall, resulting in missed seeds, reducing the garlic sowing efficiency and reducing the garlic harvest. Therefore, it is urgent to design a device that can achieve accurate single-grain garlic seed extraction. 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 type garlic single seed taking device, which can reduce the garlic sowing re-seeding rate and seed missing rate and realize the accurate single seed taking of garlic.

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

[0006] An elastic opening and closing type single-grain garlic seed taking device comprises 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 is open at the top and has an opening at the bottom that can only pass through the chain and the elastic opening and closing type seed taking spoon. The transmission shaft, the sprocket, and the chain with ears are powered by a power device. The elastic opening and closing type seed taking spoon is equidistantly installed 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 installed on the inner wall of the seed box on the 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 realize 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, and 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 comprises 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 of one side close to the ear chain, three connecting plates are provided on the rear side, and a hemispherical groove is provided at the lower interior of 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 taking spoon opening device is composed of a baffle rod, a limit rod, a limit bolt and a nut. The limit bolt passes through the baffle rod, the limit nut, the flange nut and the straight slot on the rear wall of the seed box and is fixed to the frame. Loosening the flange nut can move the bolt left and right so that the baffle rod can adapt to the elastic opening and closing seed taking spoons of different sizes and control the opening time of the opening and closing side walls of the seed taking spoon. The limit rod is fixed below the straight slot, and the baffle 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: the chain with ears drives the elastic opening and closing type seed taking spoon to perform circular motion in the seed box, and garlic seeds are placed in the seed box. When the elastic opening and closing type seed taking spoon passes through the seed box, it scoops up multiple garlic seeds. After scooping up the garlic seeds, the elastic opening and closing type seed taking spoon continues to move upward with the chain. When passing through the seed taking spoon opening device, the two opening and closing side walls of the elastic opening and closing type seed taking spoon are opened in sequence and the torsion spring is compressed. After passing through the opening device, the opening and closing side walls eject the excess garlic seeds on both sides of the hemispherical groove in sequence under the elastic force of the torsion spring, and only one garlic seed is retained in the hemispherical groove, thereby reducing the duplicate planting rate and the missed planting rate, and realizing single seed taking. The position of the seed taking spoon opening device is adjusted by loosening the limit bolt, and the opening position and opening time of the opening and closing side walls can be controlled to realize single seed taking of garlic seeds of different particle sizes. The present invention adopts the principle of taking more and leaving one, first taking more than two seeds to ensure that no missed seeds are taken, and then the elastic opening and closing side walls remove the excess seeds to prevent duplicate planting.

DETAILED DESCRIPTION

[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 type seed taking spoon 1. The seed box 3 is open at the top, and an opening 11 is opened at the bottom, which can only pass through the chain and the elastic opening and closing type seed taking spoon. The transmission shaft 7, the sprocket 5, and the chain with ears 6 are powered by a power device. The elastic opening and closing type 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 type 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 type seed taking spoon 1 to realize the 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 position of 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 achieve their connection.

[0024] Specifically, a rectangular seed retaining plate 22 is provided at the top of the seed taking spoon body 18 close to the ear chain 6 to prevent garlic seeds from falling during the sowing stage after the seed taking spoon is laid flat. Three connecting plates 13 are provided on the rear side. Each connecting plate 13 has two circular holes. The connecting plate 13 is connected to the ear plate 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 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 taking spoon opening device 2 is composed of a baffle rod 27, a limiting rod 9, a limiting nut 26, and a limiting bolt 28. The limiting bolt 28 passes through the baffle 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 baffle rod 27 can reach and open the opening and closing side walls 21 of seed taking spoons of different sizes. Therefore, the seed taking spoon opening device 2 can adapt to the elastic opening and closing seed taking spoons 1 of different sizes and control the opening time of the opening and closing side walls of the seed taking spoon. The limiting rod 9 is fixed below the straight slot 8, and the baffle rod 27 rotates between the limiting rod 9 and the limiting bolt 28.

[0027] Specifically, the seed taking spoon opening device 2 is arranged on both sides of the elastic opening and closing seed taking spoon 1 and is staggered in position up and down to realize the opening and closing side walls 21 on both sides to open in sequence, to prevent 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 taking 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 a part of the 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. After that, 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, and 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, so that a single garlic seed is taken out.

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