DETAILED DESCRIPTION

[0016] The present invention will be further described below in conjunction with the accompanying drawings: The directional nouns involved in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application according to the visual orientation shown in the accompanying drawings. Unless otherwise clearly specified and limited, the terms "setting", "installation", "connection", etc. should be understood in a broad sense. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0017] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a garlic sowing device for garlic planting comprises a mounting carrier 1, a fixing frame 7 is fixedly connected to the mounting carrier 1, a straight slide 701 is fixedly opened in the middle of the fixing frame 7, a conical slide 702 is fixedly connected to the bottom of the straight slide 701, a bracket 703 is fixedly connected to the bottom of the fixing frame 7, a limiting disk 704 is fixedly connected to the bottom of the bracket 703, a seed taking bin 3 is fixedly installed on the top of the fixing frame 7, a reseeding mechanism 6 is arranged inside the seed taking bin 3, a seed storage bin 2 is fixedly installed on the top of the seed taking bin 3, a seed cavity 201 is arranged on the upper part of the seed storage bin 2, a conical opening 201A is fixedly opened at the bottom center of the seed cavity 201, a partition cavity 202 is fixedly connected to the bottom of the seed cavity 201, and a conical seat 202B is fixedly connected to the bottom center of the partition cavity 202 , a plurality of groups of seed dropping openings 202A are fixedly provided on the outer side of the bottom of the partition cavity 202. By setting the partition cavity 202 at the bottom of the seed cavity 201, the seed cavity 201 can be used to store garlic seeds to be sown, and the garlic seeds can be prevented from being damaged by the rotation and squeezing of the seed taking rotating frame 303 during the process of passing through the seed dropping opening 202A and falling into the seed dropping groove 303B under gravity. When there is already a garlic seed in the seed dropping groove 303B, other garlic seeds can be squeezed upward out of the seed dropping opening 202A when being squeezed by the rotation of the seed taking rotating frame 303. If the partition cavity 202 is not set, the garlic seeds are easily unable to move upward due to the gravity of the garlic seeds on the upper part of the seed storage bin 2, resulting in the garlic seeds being firmly pressed between the seed dropping groove 303B and the seed dropping opening 202A and being squeezed and broken.

[0018] A power mechanism 4 is fixedly provided on the top of the seed storage bin 2, and the power mechanism 4 includes a fixed plate 402, a motor 407 and a driven wheel 406. An electric push rod 401 is fixedly connected to the fixed plate 402, and the push rod end of the electric push rod 401 is fixedly connected to the top of the seed storage bin 2. An extrusion slide rod 403 is fixedly connected to the center of the bottom of the fixed plate 402. A through groove 403B is fixedly opened on the inner wall of the bottom of the extrusion slide rod 403. An extrusion disk 403A is fixedly connected to the bottom of the extrusion slide rod 403. The motor 407 is fixedly connected to the top of the seed storage bin 2, and the output shaft of the motor 407 is fixedly connected to the driving wheel 404. The driving wheel 404 and the driven wheel 406 are commonly connected with a belt 405. Fig.12 As shown, a positive bud sowing mechanism 5 is fixedly installed at the bottom of the fixed frame 7.

[0019] like Figure 5 , Figure 6 , Figure 7 and Fig.10As shown, a seed taking rotating chamber 301 is provided inside the seed taking rotating chamber 3, and an elastic push ring 301A is fixedly connected to the inner wall of the upper part of the seed taking rotating chamber 301. By setting the elastic push ring 301A, the garlic seeds falling into the seed dropping groove 303B can be pushed inward into the vertical seed storage groove 302B, and then fall downward from the vertical seed storage groove 302B into the horizontal seed storage groove 302E; a seed taking rotating chamber 301 is fixedly provided with a seed taking boss 302 at the bottom center, and an inner cavity 302A is fixedly opened at the upper center of the seed taking boss 302. The inner wall of 302A is fixedly connected with a limited position convex rod 302D, the inner cavity 302A cooperates with the straight slide 701, the upper outer wall of the seed taking boss 302 is fixedly provided with two groups of vertical seed storage grooves 302B, and the lower inner wall of the seed taking boss 302 is fixedly provided with two groups of horizontal seed storage grooves 302E. By providing two groups of horizontal seed storage grooves 302E and two groups of vertical seed storage grooves 302B, when one group cannot push the garlic seeds into the seed storage bin 601 in time due to an accident, the other group can push the garlic seeds in time to realize the replanting operation; The vertical seed storage groove 302B is matched with the horizontal seed storage groove 302E, and a ring groove 1 302C is fixedly provided on the outer wall of the lower part of the seed taking boss 302. A seed taking rotating frame 303 is rotatably provided in the seed taking rotating chamber 301. The inner wall of the seed taking rotating frame 303 is rotatably connected with the outer wall of the seed taking boss 302, and the outer wall of the seed taking rotating frame 303 is rotatably connected with the inner wall of the seed taking bin 3. By setting the seed taking bin 3, the garlic seeds are taken out from the seed storage bin 2 one by one, and the garlic seeds are arranged in a single row in the horizontal seed storage groove 302E, and the elastic push ring 2 303D is used to push the garlic seeds one by one into the seed placing bin 601, thereby realizing uniform sowing of the garlic seeds.

[0020] like Figure 8 , Fig. 9 and Fig.11 As shown, a transmission shaft tube 303A is fixedly connected to the top center of the seed taking rotating frame 303, and the top of the transmission shaft tube 303A is fixedly connected to the driven wheel 406. The transmission shaft tube 303A is driven by the motor 407, and further drives the seed taking rotating frame 303 to rotate. As the seed taking rotating frame 303 rotates, the seed dropping groove 303B contacts the seed dropping port 202A in turn, and the garlic seeds enter the seed dropping groove 303B one by one under the action of gravity and rotate accordingly. When the seed dropping groove 303B rotates to contact the vertical seed storage groove 302B, the garlic seeds are pushed by the elastic push ring 1 301A and enter the vertical seed storage groove 302B inwardly, and fall into the horizontal seed storage groove 302E under the action of gravity. Since the horizontal seed storage groove 302E cooperates with the elastic push ring 2 303D, The garlic seeds in the horizontal seed storage groove 302E are pushed by the elastic push ring 2 303D and continuously move inward, and finally enter the seed storage bin 601; The inner wall of the transmission shaft tube 303A is rotatably connected to the outer wall of the extrusion slide bar 403, and a plurality of seed dropping grooves 303B are fixedly provided on the upper inner wall of the seed taking rotating frame 303, and the seed dropping grooves 303B cooperate with the vertical seed storage grooves 302B. A second ring groove 303C is fixedly provided on the upper outer wall of the seed taking rotating frame 303, and the second ring groove 303C cooperates with the first elastic push ring 301A. A second elastic push ring 303D is fixedly connected to the lower inner wall of the seed taking rotating frame 303, and the second elastic push ring 303D cooperates with the first ring groove 302C, and the second elastic push ring 303D cooperates with the horizontal seed storage groove 302E.

[0021] like Fig.13 , Fig.14 , Fig.15 and Fig.16 As shown, the reseeding mechanism 6 includes a seed placing bin 601, a seed passing port 601A is fixedly provided on the lower side wall of the seed placing bin 601, a limit guide groove 601B is fixedly provided on the upper outer wall of the seed placing bin 601, an inner retaining ring 601C is fixedly connected to the inner wall of the middle part of the seed placing bin 601, and a compression spring 603 is slidably contacted with the outer wall of the top of the seed placing bin 601, and the other end of the compression spring 603 is fixedly connected to a detection pressure rod 602. Under the push of the compression spring 603, the detection pressure rod 602 allows the lower limit plate 602B to remain close to the bottom of the extrusion disk 403, so as to avoid the detection pressure rod 602 blocking the area of ​​the seed passing port 601A for a long time, resulting in blockage of the seed passing port 601A and affecting the seeding effect; the detection pressure rod 6 02 is fixedly connected with an upper limit plate 602A at the top, and the bottom of the upper limit plate 602A is fixedly connected with a compression spring 2 603, and the bottom of the detection pressure rod 602 is fixedly connected with a lower limit plate 602B, and the detection pressure rod 602 is slidably connected with the through slot 403B. The upper limit plate 602A and the lower limit plate 602B are respectively located at the upper and lower parts of the extrusion disk 403A, and the bottom of the extrusion disk 403A cooperates with the inner stop ring 601C. When the extrusion disk 403A moves downward, the top of the inner stop ring 601C is squeezed, so that the seed placement bin 601 moves downward for a distance; the top of the extrusion disk 403A is fixedly connected with a compression spring 3 604, and the other end of the compression spring 3 604 is in sliding contact with the inner wall of the top of the seed placement bin 601.

[0022] By setting up the reseeding mechanism 6, the extrusion slide rod 403 drives the extrusion plate 403A to move upward and press downward through a set of processes, so as to detect whether there are garlic seeds in the seed placement bin 601. If there are garlic seeds, the garlic seeds will fall when the seed placement bin 601 is pressed downward. If there are no garlic seeds, the seed placement bin 601 is guided by the limiting convex rod 302D during the upward movement and rotates. At this time, the seed placement bin 601 rotates 180 degrees, passes through the seed opening 601A toward another set of horizontal seed storage grooves 302E, and the garlic seeds enter the seed placement bin 601 for subsequent sowing operations, thereby ensuring the sowing effect and avoiding the phenomenon of missing seeds.

[0023] like Fig.17 and Fig.18 As shown, the outer diameter of the lower limit plate 602B is smaller than the inner diameter of the inner retaining ring 601C, and the limit guide groove 601B is slidably matched with the limit convex rod 302D. When there are no garlic seeds in the seed storage bin 601, the seed storage bin 601 can move upward to the upper part of the inner cavity 302A, so that the limit guide groove 601B contacts the limit convex rod 302D. Each contact can make the seed storage bin 601 rotate 180 degrees, so that the seed port 601A contacts and cooperates with another set of horizontal seed storage grooves 302E. The seed port 601A cooperates with the horizontal seed storage grooves 302E.

[0024] like Fig.19 and Fig. 20 As shown, the positive bud sowing mechanism 5 includes a seed tube 501, the top of the seed tube 501 is rotatably connected to the bottom of the seed placing bin 601, the top side wall of the seed tube 501 is rotatably connected to a fan-shaped stopper 501A, the fan-shaped stopper 501A is fixedly connected to a torsion spring 501B, and the other end of the torsion spring 501B is fixedly connected to the seed tube 501. Under the torsion of the torsion spring 501B, the fan-shaped stopper 501A maintains a tendency to open outwards. When the fan-shaped block 501A moves to contact the straight slide 701, the outer side of the fan-shaped block 501A is squeezed to overcome the rotation of the torsion spring 501B and retract, and several groups of fan-shaped blocks 501A block the lower seed tube 1 501. When the fan-shaped block 501A moves to contact the conical slide 702, the fan-shaped block 501A rotates and opens under the drive of the torsion spring 501B, and the lower seed tube 1 501 is opened; the straight slide 701 and the conical slide The paths 702 are all matched with the fan-shaped stopper 501A. The bottom of the lower seed tube 501 is fixedly connected with a positive bud cone 502. By setting the positive bud cone 502, due to the structural shape of the garlic seed itself, the root of the garlic seed is heavier and the bud part is lighter. Under the friction contact with the inner wall of the positive bud cone 502, the garlic seed can keep the bud part facing upward and fall into the lower seed tube 2 503. The inside of the positive bud cone 502 is fixedly connected with a cone baffle. 502A, by setting the cone baffle 502A, it can ensure that the garlic seeds are in contact with the positive bud cone 502, and prevent them from falling directly from the lower seeding tube 1 501 into the lower seeding tube 2 503; the lower seeding tube 2 503 is fixedly connected to the bottom of the positive bud cone 502, the upper outer wall of the lower seeding tube 2 503 is fixedly connected to the fixed retaining ring 503A, the bottom of the lower seeding tube 2 503 is fixedly connected to the rotating seat 503B, and the bottom of the lower seeding tube 2 503 is provided with a sowing assembly 504. By setting the sowing assembly 504, after the garlic seeds after the positive bud treatment are inserted into the soil, the sowing bucket 504A is opened to ensure that the garlic seeds can still keep the buds facing upward when sowing into the soil, so as to avoid the situation where the garlic seeds fall freely into the soil and accidentally flip, which causes the direction of the buds to change.

[0025] like Fig.21 and Fig. 22As shown, the sowing assembly 504 includes a sowing bucket 504A, a rotating hole 504B is fixedly provided on the top of the sowing bucket 504A, the rotating hole 504B is rotatably connected to the rotating seat 503B, a rotating shaft 504C is fixedly provided at the rear of the sowing bucket 504A, the rotating shaft is rotatably connected to a connecting rod 504D, the other end of the connecting rod 504D is rotatably connected to a dynamic stop ring 504E, the dynamic stop ring 504E is slidably connected to the outer wall of the lower seed tube 503, a compression spring 504F is fixedly connected to the top of the dynamic stop ring 504E, the other end of the compression spring 504F is fixedly connected to the fixed stop ring 503A, and the dynamic stop ring 504E cooperates with the limit plate 704. Driven by the compression spring 504F, the dynamic stop ring 504E keeps squeezing the sowing bucket 504A downward, and the sowing bucket 504A is tightly closed. When the sowing assembly 504 continues to move downward, the dynamic stop ring 504E contacts and is squeezed by the limit plate 704. At this time, the dynamic stop ring 504E overcomes the elastic force of the compression spring 504F and moves upward relative to the fixed stop ring 503A. At this time, the sowing bucket 504A opens, and the garlic seeds fall into the soil, completing the sowing operation.

[0026] Working principle: 1. Pour the garlic seeds into the seed cavity 201 from the seed inlet 201B. Under the action of gravity, the garlic seeds fall into the partition cavity 202 through the conical opening 201A and slide to the outside of the partition cavity 202 under the guidance of the conical seat 202B. 2. As the motor 407 drives the seed taking rotating frame 303 to rotate, when the seed dropping groove 303B rotates to contact the seed dropping opening 202A, the garlic seeds enter the seed dropping groove 303B. As the seed taking rotating frame 303 continues to rotate, the seed dropping groove 303B contacts the vertical seed storage groove 302B. The garlic seeds enter the vertical seed storage groove 302B from the seed dropping groove 303B under the push of the elastic push ring 1 301A, and fall into the horizontal seed storage groove 302E at the bottom of the vertical seed storage groove 302B under the action of gravity; 3. As the seed taking rotating frame 303 continues to rotate, the elastic push ring 2 303D is driven to push the garlic seeds to move to the inside of the horizontal seed storage groove 302E; 4. The electric push rod 401 moves upward, and the extrusion slide bar 403 and the extrusion plate 403A move upward. The extrusion plate 403A presses the compression spring 603 upward, and the compression spring 603 drives the seed placement bin 601 and the positive bud sowing mechanism 5 to move upward. When the seed passing port 601A of the seed placement bin 601 contacts the horizontal seed storage groove 302E, the fan-shaped block 501A is closed, and the seed lowering tube 1 501 is closed. The garlic seeds enter the seed placement bin 601 under the push of the elastic push ring 2 303D. At this time, the following two situations occur: 4A, the garlic seeds completely enter the seed placement bin 601. At this time, as the extrusion slide bar 403 and the extrusion plate 403A continue to move upward, the upper limit plate 602A on the upper part of the detection pressure rod 602 moves to the top of the inner cavity 302A and cannot move upward any further. However, the extrusion plate 403A continues to push the seed placement bin 601 upward through the compression spring three 604. Since there are garlic seeds inside the seed placement bin 601, the top of the garlic seeds contacts the lower limit plate 602B, and the seed placement bin 601 cannot move upward any further. At this time, the compression spring three 604 is compressed, and then gradually recovers as the extrusion slide bar 403 moves downward, and presses the inner stop ring 601C downward, driving the seed placement bin 601 and the positive bud sowing mechanism 5 to move downward. 4B. The garlic seeds do not enter the seed placement bin 601 due to an accident. At this time, as the extrusion slide bar 403 and the extrusion plate 403A continue to move upward, the upper limit plate 602A on the upper part of the detection pressure bar 602 moves to the top of the inner cavity 302A and cannot move upward any further. However, the extrusion plate 403A continues to push the seed placement bin 601 upward through the compression spring 3 604. Since there are no garlic seeds inside the seed placement bin 601, the seed placement bin 601 can continue to move upward, and the limiting guide groove 601B contacts the limiting convex rod 302D, so that the seed placement bin 601 rotates 180 degrees and moves downward as the extrusion slide bar 403 moves downward. At this time, the seed port 601A faces another set of horizontal seed storage grooves 302E, allowing the garlic seeds to be replanted into the seed placement bin 601 for replanting operations. 5. As the extrusion slide bar 403 continues to move downward, the seed placement bin 601 and the bud correcting sowing mechanism 5 move downward. When the fan-shaped block 501A moves to the cone slide 702, the fan-shaped block 501A opens, and the garlic seeds fall into the seed placement tube 1 501 and enter the bud correcting cone 502 to perform the bud correcting operation; 6. After the garlic seeds have been processed for sprouting, they pass through the seed tube 503 and fall into the sowing bucket 504A. After the sowing bucket 504A is inserted downward into the soil, the dynamic retaining ring 504E contacts the limiting plate 704, so that the sowing bucket 504A opens, completing a sowing operation.

[0027] The present invention sets a reseeding mechanism 6, and the extrusion slide rod 403 drives the extrusion plate 403A to move upward and press downward through a set of processes, so as to detect whether there are garlic seeds in the seed placement bin 601. If there are garlic seeds, the garlic seeds fall when the seed placement bin 601 is pressed downward. If there are no garlic seeds, the seed placement bin 601 is guided by the limiting convex rod 302D during the upward movement and rotates. At this time, the seed placement bin 601 rotates 180 degrees, passes through the seed opening 601A toward another set of horizontal seed storage grooves 302E, and the garlic seeds enter the seed placement bin 601 for subsequent sowing operations, thereby ensuring the efficiency of sowing. The effect is to avoid missing seeds; by setting the bud cone 502, due to the structural shape of the garlic seeds themselves, the roots of the garlic seeds are heavier and the buds are lighter. When the garlic seeds are in friction contact with the inner wall of the bud cone 502, the garlic seeds can keep the buds facing upward and fall into the lower seed tube 503; by setting the sowing component 504, after the garlic seeds with the buds processed are inserted into the soil, the sowing bucket 504A is opened to ensure that the garlic seeds can still keep the buds facing upward when they are sown into the soil, avoiding the garlic seeds from falling freely into the soil and accidentally flipping over, which causes the direction of the buds to change.
