[0017] 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.

[0018] like Figure 1 , Figure 2 and Figure 3As shown, a garlic seeder comprises a frame 1, both sides of the bottom of the frame 1 are rotatably connected with walking wheels 101, the front end of the bottom of the frame 1 is fixedly connected with a trenching wedge 102, and the rear end of the bottom of the frame 1 is fixedly connected with a soil gathering board 103. When the walking wheels 101 rotate and the seeder moves forward, the trenching wedge 102 digs trenches on the land, and the garlic seeds fall into the trenches. Under the push of the soil gathering board 103, the garlic is covered with soil; a seeding assembly 2 is fixedly provided on the top of the frame 1, and by setting the seeding assembly 2, the garlic seeds in the seed bin 201 are taken out by the rotation of the seeding wheel 203 and discharged downward from the opening 202A; the seeding assembly 2 The utility model comprises a seed bin 201, a seed placement cover 202 is fixedly connected to the rear of the seed bin 201, an opening 202A is fixedly opened at the bottom of the seed placement cover 202, a seed placement wheel 203 is rotatably connected to the seed bin 201, a plurality of seed taking spoons 203A are fixedly connected to the seed placement wheel 203, and the volume of the seed taking spoon 203A is designed to accommodate the volume of only one garlic seed, so that the garlic seed can be taken out from the seed bin 201 individually. Due to the obstruction of the seed placement cover 202, as the seed placement wheel 203 rotates, the garlic seeds cannot be gathered together even if the opening 202A of the seed taking spoon 203A turns downward, so as to ensure that the garlic seeds fall from the opening 202A individually.

[0019] The seeding spoon 203A is in sliding contact with the inner wall of the seeding cover 202. A driving motor 204 is fixedly connected to the side wall of the seeding bin 201. The output shaft of the driving motor 204 is fixedly connected to the seeding wheel 203. The rotation of the driving motor 204 can drive the seeding wheel 203 to rotate, thereby taking out the garlic seeds in the seeding bin 201 and performing the sowing operation. A pre-sprouting component 3 is fixedly arranged below the seeding component 2. By setting the pre-sprouting component 3, during the falling process of the garlic seeds, the garlic seeds are in contact and rubbed with the inner wall of the sprouting cone tube 302. Since the center of gravity of the garlic is far away from the sprouting part, the sprouting part of the garlic seeds is easily deflected to an upward direction during friction, so that the sprouting operation of most garlic seeds is achieved. Since the seeder will generate vibration and the inertia of the frame movement during the sowing process, it is difficult to ensure a higher sprouting rate by relying solely on the pre-sprouting component 3. Therefore, the cooperation of the sprouting component 4 is required to perform accurate sprouting operations on the missed garlic seeds. Through the cooperation of the two, the sprouting effect of the garlic seeds is greatly improved. A bud correction component 4 is fixedly provided below the pre-bud correction component 3. Figure 7 and Figure 8 As shown, the positive bud component 4 is slidably connected to a through block 5 and a connecting sliding frame 6, and the connecting sliding frame 6 is rotatably connected to a positive bud rotating drum 7.

[0020] By setting the positive bud rotating drum 7, the inside of the positive bud rotating drum 7 is respectively provided with two groups of seed storage chambers 701A facing upward and downward. When the first garlic seed with the wrong bud direction falls into the upper seed storage chamber 701A, the garlic seed is temporarily stored. As the connecting sliding frame 6 moves forward, the positive bud rotating drum 7 is turned over, and the first stored garlic seed is turned over with the seed storage chamber 701A. At this time, the bud facing upward is the correct posture. When garlic seeds with the wrong bud direction appear later, the positive bud rotating drum 7 only needs to follow the connecting sliding frame 6 to move backward until it is connected and matched with the positive bud assembly 4, then the previously stored garlic seed is directly stored with the correct posture. The garlic seeds continue to fall from the seed storage chamber 701A, while the garlic seeds with wrong postures are stored for the subsequent correct sprouting operation. This operation method can ensure that the garlic seeds can fall continuously into the soil. When the garlic seeds are found to be upside down, the garlic seeds with correct postures can be immediately supplemented and dropped, avoiding the slow process of finding the garlic seeds upside down - correcting the upside down garlic seeds - continuing to drop the corrected garlic seeds during the rapid sowing operation of the seeder. By setting the correct sprouting rotating drum 7, the correct sprouting operation is changed to: storing an upside down garlic seed in advance and correcting it - finding the garlic seeds upside down - dropping the stored garlic seeds quickly. The sowing speed limit of the seeder with the correct sprouting function is greatly improved.

[0021] By setting the positive bud component 4, the through block 5, the connecting slide frame 6 and the positive bud rotating drum 7, when the bud sensor 304 senses that the garlic seeds are falling in the correct posture with the buds facing upward, the through block 5 keeps cooperating with the positive bud component 4, so that the garlic seeds can directly fall into the soil through the positive bud component 4; when the bud sensor 304 senses that the garlic seeds are falling in the wrong posture with the buds facing downward, the connecting slide frame 6 drives the positive bud rotating drum 7 to move backward, so that the positive bud rotating drum 7 replaces the through block 5 to connect and cooperate with the positive bud component 4, ensuring that the garlic seeds fall into the soil in the correct posture.

[0022] like Figure 4As shown, the pre-sprouting component 3 includes a sprouting cone tube 302, which is fixedly connected to the frame 1, and a seed-scattering block 301 is fixedly connected to the inner wall of the sprouting cone tube; a seed-dropping tube 303 is fixedly connected to the bottom of the sprouting cone tube 302, and a sprouting sensor 304 is fixedly connected to the side wall of the seed-dropping tube 303. By providing the seed-scattering block 301, the garlic seeds can slide down close to the inner wall of the sprouting cone tube 302, including the garlic seeds can have a long enough distance to fully fit and rub against the inner wall of the sprouting cone tube 302 during the falling process, so as to perform pre-sprouting operation on the garlic seeds. When the garlic seeds fall from the seed dropping tube 303, the garlic bud sensor 304 scans and judges the garlic seeds. When the garlic seeds fall in a correct posture, the pneumatic telescopic rod 402A does not move. At this time, the pass block 5 is connected and cooperated with the positive bud component 4, and the garlic seeds can fall directly. When the garlic seeds fall in an incorrect posture, the pneumatic telescopic rod 402A drives the connecting slide frame 6 to move backward and push open the pass block 5, so that the positive bud rotating cylinder 7 is connected and cooperated with the positive bud component 4, and the garlic seeds are turned around.

[0023] like Figure 5 , Figure 6 and Fig. 9 As shown, the positive bud component 4 includes an installation shell 401, and a seed inlet 401A is fixedly opened on the top of the installation shell 401, and the top of the seed inlet 401A is connected to the seed drop tube 303; a seed placement port 401C is fixedly opened at the bottom of the installation shell 401, and the bottom of the seed placement port 401C is connected to the rear part of the trenching wedge 102; a limiting groove 401D is fixedly opened on the inner wall of the rear end of the installation shell 401, and a slide groove 401B is fixedly opened on the side wall of the front end of the installation shell 401, and the slide groove 401B includes a horizontal groove and a vertical groove, and the front of the installation shell 401 is fixedly connected A front plate 402 is connected, and a pneumatic telescopic rod 402A is fixedly connected to the front of the front plate 402. A push plate 403 is fixedly connected to the push rod end of the pneumatic telescopic rod 402A. The push plate 403 is slidably connected to the outer wall of the mounting shell 401. A guide groove 403A is fixedly provided on the push plate 403. The guide groove 403A is designed to be inclined. The guide groove 403A gradually deviates from the bottom to the top of the pneumatic telescopic rod 402A. The guide groove 403A cooperates with the slide groove 401B to move the connecting slide frame 6; a steering top block 402B is fixedly connected to the rear of the front plate 402. The rotating top block 402B contacts the top rod 702B once, which can make the top rod 702B rotate 180 degrees, drive the positive bud rotating drum 7 to flip once, and complete the reversal of the garlic seeds.

[0024] like Fig.10As shown, the two sides of the through block 5 are fixedly connected with the limiting protrusions 501, and the limiting protrusions 501 are slidably connected with the limiting grooves 401D. When the limiting protrusions 501 slide to the front end position on the limiting grooves 401D, the top of the straight through grooves 503 on the through block 5 is aligned with the seed inlet 401A, and the bottom of the straight through grooves 503 is aligned with the seed outlet 401C. At this time, the garlic seeds can directly fall into the soil through the straight through grooves 503. The through block 5 is fixedly provided with the straight through grooves 503, and the front end of the through block 5 is fixedly connected with the tension spring 502, and the other end of the tension spring 502 is fixedly connected with the connecting slide frame 6. Due to the existence of the tension spring 502, the through block 5 and the connecting slide frame 6 remain in contact with each other without strong external pulling.

[0025] like Fig.11 and Fig.12 As shown, sliders 601 are fixedly connected on both sides of the connecting slide frame 6, the sliders 601 are slidably connected to the slide groove 401B, guide columns 602 are fixedly connected to the outer side of the slider 601, the guide columns 602 are slidably connected to the guide groove 403A, a rotating hole 603 is fixedly opened on the connecting slide frame 6, a slot 603A is fixedly opened on the inner wall of the rotating hole 603, a compression spring 604 is fixedly connected to the bottom of the slot 603A, the other end of the compression spring 604 is fixedly connected to a positioning block 605, and the positioning block 605 is slidably connected to the slot 603A. When the pneumatic telescopic rod 402A pushes the push plate 403 backward, the guide groove 403A squeezes the guide column 602 backward, and the slider 601 slides backward along the horizontal groove. When the slider 601 slides to the rearmost end of the horizontal groove, the guide groove 403A continues to squeeze the guide column 602 backward, so that the slider 601 begins to move upward along the vertical groove, thereby making the positive bud rotating drum 7 move upward and close to the seed inlet 401A. At this time, the extrusion slide 8 moves downward relative to the positive bud rotating drum 7.

[0026] like Fig.13 and Fig.14 As shown, the positive bud rotating drum 7 includes a cylinder body 701, and rotating columns 702 are fixedly connected to the outer walls on both sides of the cylinder body 701. The rotating columns 702 are rotatably connected to the rotating holes 603. A positioning groove 702A is fixedly provided on the side wall of the rotating column 702. The positioning groove 702A cooperates with the positioning block 605. The positioning block 605 is inserted into the positioning groove 702A under the push of a compression spring 604, and a certain resistance is applied to the continued rotation of the positive bud rotating drum 7 to prevent the positive bud rotating drum 7 from rotating easily. At the same time, the setting of the positioning groove 702A and the positioning block 605 can guide the positive bud rotating drum 7 within a certain angle range, so as to promote the positive bud rotating drum 7 to complete the posture adjustment. A push rod 702B is fixedly connected to the rotating column 702 located at the front part of the cylinder 701, and the push rod 702B extends forward. When the positive bud rotating drum 7 moves forward to a certain position, the push rod 702B contacts and squeezes the steering top block 402B, and applies torque to the positive bud rotating drum 7 in the reverse direction, causing the positive bud rotating drum 7 to flip over, thereby completing the positive bud operation of the garlic seeds.

[0027] Two groups of seed storage cavities 701A are fixedly opened inside the cylinder 701, and a partition 701B is fixedly set between the seed storage cavities 701A. A slideway 703 and a rotating groove 704 are fixedly opened on the inner wall of the cylinder 701, and a rotating rod 704A is fixedly connected to the rotating groove 704. An annular groove 705 is fixedly opened on the outer side of the inner wall of the cylinder 701, and an extrusion slide 8 is also provided on the cylinder 701. By arranging an extrusion slide 8 in the positive bud rotating cylinder 7, when the positive bud rotating cylinder 7 is driven by the connecting slide frame 6 to push upward into the seed port 401A, the extrusion slide 8 slides downward relative to the positive bud rotating cylinder 7. At this time, the elastic pressure plate 9 in the upper seed storage cavity 701A is squeezed downward by the extrusion block 802A and approaches the partition 701B. At this time, the space of the seed storage cavity 701A becomes larger, and the garlic seeds can fall completely into the seed storage cavity 701A. Under the action of the torsion spring 1001, the bottom of the limiting block 10 deflects toward the center of the seed storage cavity 701A, and while squeezing the garlic seeds, it clamps the top of the elastic pressure plate 9 to prevent it from popping out. At the same time, the elastic pressure plate 9 in the seed storage chamber 701A at the bottom has been stuck by the limiting block 10, and the downward movement of the extrusion slide 8 drives the top ring 803 below to squeeze the outside of the limiting block 10 downward, so that the limiting block 10 overcomes the torque of the torsion spring 1001 and gradually changes to a vertical posture. The end of the limiting block 10 close to the partition 701B gradually separates from the elastic pressure plate 9, and the elastic pressure plate 9 is quickly ejected under the push of the compression spring three 901. The space of the seed storage chamber 701A at the bottom is rapidly reduced, and the garlic seeds in the seed storage chamber 701A are ejected downward, so that the garlic seeds quickly pass through the seed opening 401C and fall to the ground.

[0028] like Fig.15 and Fig.16 As shown, both sides of the partition 701B are fixedly connected with compression springs 3 901, and the other end of the compression springs 3 901 is fixedly connected with an elastic pressure plate 9, and the elastic pressure plate 9 is slidably connected to the inner wall of the seed storage chamber 701A. The rotating rod 704A is rotatably connected with a limited clamping block 10, and the rotating rod 704A is also fixedly connected with a torsion spring 1001, and the other end of the torsion spring 1001 is fixedly connected with the limited clamping block 10. The elastic pressure plate 9 is pushed downward by the extrusion block 802A to squeeze the compression spring 3 901 and approach the partition 701B, where the space of the seed storage chamber 701A becomes larger, and when the elastic pressure plate 9 moves down to a certain position, the limited clamping block 10 deflects and clamps the elastic clamping plate to prevent it from extending. When the limited clamping block 10 is squeezed by the top ring 803 and deflected in the reverse direction, the elastic pressure plate 9 loses its restriction and quickly extends out under the push of the compression spring 3 901, away from the partition 701B, where the space of the seed storage chamber 701A becomes smaller.

[0029] like Fig.17 and Fig.18As shown, the extrusion slide 8 includes a slide bar 802, which is slidably connected to the slideway 703. An extrusion block 802A is fixedly connected to the inner side wall of the slide bar 802. A plurality of extrusion blocks 802A are provided on the slide bar 802. The extrusion block 802A cooperates with the elastic pressure plate 9. When the extrusion block 802A approaches the elastic pressure plate 9, the elastic pressure plate 9 is pressed down to expand the space of the seed storage cavity 701A. When the extrusion block 802A is away from the elastic pressure plate 9, the elastic pressure plate 9 is given space to extend. A top ring 803 is fixedly connected to the outer side wall of the slide bar 802, and the top ring 803 is slidably connected to the ring groove 705. The top ring 803 cooperates with the limit block 10. When the top ring 803 is away from the limit block 10, the limit block 10 is only deflected into the seed storage cavity 701A by the action of the torsion spring 1001; when the top ring 803 approaches and squeezes the limit block 10, the limit block 10 overcomes the torque of the torsion spring 1001 and moves out of the seed storage cavity 701A; both ends of the slide bar 802 are fixedly connected to the pressure ring 801, and the pressure ring 801 is fixedly connected to the pressure spring 2 804, and the other end of the pressure spring 2 804 is fixedly connected to the outer wall of the cylinder 701. By setting the pressure spring 2 804, the extrusion slide 8 can be kept in the middle position of the positive bud rotating cylinder 7 without external force, so as to prepare for the next upward or downward movement of the extrusion slide 8.

[0030] Working principle: 1. Place the garlic seeds in the seed bin 201, start the drive motor 204, rotate the seed placement wheel 203, take out the garlic seeds with the seed spoon 203A, and let the garlic seeds fall one by one from the opening 202A; 2. The garlic seeds fall into the pre-bud assembly 3, and the buds face upwards due to the contact and friction with the bud cone tube 302, and fall into the seed drop tube 303. The bud sensor 304 determines the posture of the garlic seeds; A: When the garlic seed buds face upwards, the posture is correct, the pneumatic telescopic rod 402A does not work, the straight slot 503 on the through block 5 cooperates with the seed inlet 401A and the seed placement port 401C, and the garlic seeds directly pass through the straight slot 503 and fall to the ground; B: The garlic seed buds are facing downwards, with the wrong posture. The pneumatic telescopic rod 402A is extended to the farthest distance, and the connecting slide frame 6 squeezes the through block 5 backwards, so that the positive bud rotating drum 7 is aligned with the seed inlet 401A and the seed placement port 401C. After the connecting slide frame 6 slides backwards to the farthest, it moves upward again, and the pressure ring 801 of the squeezing slide frame 8 overcomes the elastic force of the compression spring 804 and moves downward relative to the positive bud rotating drum 7; B1. At this time, the space of the seed storage cavity 701A at the upper part gradually becomes larger, and the garlic seeds in the wrong posture fall into it from the seed inlet 401A and are clamped by the limit block 10; B2. At this time, the space of the seed storage cavity 701A at the bottom is rapidly reduced, and the garlic seeds in the correct posture fall into the soil from the seed placement port 401C, thereby ensuring the continuous and uninterrupted garlic seed sowing operation; B3, the pneumatic telescopic rod 402A is retracted to the middle distance, and the straight groove 503 on the through block 5 is aligned with the seed inlet 401A and the seed drop port 401C, allowing the subsequent garlic seeds with the correct posture to continue to fall, and the upper seed storage cavity 701A stores the garlic seeds with the wrong posture; B4, the pneumatic telescopic rod 402A is retracted to the shortest length, the through block 5 is restricted by the limit groove 401D, and the straight groove 503 continues to cooperate with the seed inlet 401A and the seed placement port 401C. The tension spring 502 is stretched and lengthened, the connecting slide frame 6 continues to move forward, and the top rod 702B contacts the turning top block 402B, so that the positive bud rotating drum 7 is turned over. At this time, the garlic seeds turn downward and the posture is correct; B5. The pneumatic telescopic rod 402A is extended to the middle distance, waiting to process the next garlic seed with the wrong posture.

[0031] The present invention realizes the sprout correction operation for most garlic seeds by setting the pre-sprout correction component 3, and the sprout correction component 4 performs accurate sprout correction operation on the missed garlic seeds. Through the cooperation of the two, the sprout correction effect of the garlic seeds is greatly improved; the traditional seeder is in a fast sowing operation: the garlic seeds are found to be upside down - the upside down garlic seeds are corrected - the corrected garlic seeds continue to fall slowly, and by setting the sprout correction rotating drum 7, the sprout correction operation is changed to: store an upside down garlic seed in advance and correct it - find the garlic seeds are upside down - the stored garlic seeds fall quickly, and the garlic seeds with correct postures can be immediately supplemented when the posture of the garlic seeds is found to be wrong, which greatly improves the sowing speed upper limit of the seeder with the sprout correction function. By setting the positive bud component 4, the through block 5, the connecting slide frame 6 and the positive bud rotating drum 7, when the bud sensor 304 senses that the garlic seeds are falling in the correct posture with the buds facing upward, the through block 5 keeps cooperating with the positive bud component 4, so that the garlic seeds can directly fall into the soil through the positive bud component 4; when the bud sensor 304 senses that the garlic seeds are falling in the wrong posture with the buds facing downward, the connecting slide frame 6 drives the positive bud rotating drum 7 to move backward, so that the positive bud rotating drum 7 replaces the through block 5 to connect and cooperate with the positive bud component 4, ensuring that the garlic seeds fall into the soil in the correct posture.
