[0006] The planting mechanism includes a garlic storage magazine and a garlic magazine fixing box. The garlic magazine fixing box has a vertically arranged first through hole inside, into which a ball head is inserted. The diameter of the first through hole is larger than the cross-sectional diameter of a single garlic seed but smaller than the sum of the cross-sectional diameters of two garlic seeds. A garlic drop cover is rotatably mounted on the bottom surface of the garlic magazine fixing box. The front side of the garlic magazine fixing box has a front opening communicating with the first through hole, forming a three-way structure. The garlic storage magazine adopts a cylindrical structure with its axis perpendicular to the front axle and horizontally arranged. The rear of the garlic storage magazine is connected to the front opening of the garlic magazine fixing box. The magazine has a sliding baffle inside, and a push spring is provided between the sliding baffle and the front end of the garlic storage magazine. The push spring is used to push the sliding baffle to move backward. The garlic storage magazine has a groove extending along the axial direction of the garlic storage magazine. The front of the groove has a locking port. The sliding baffle is connected to a handle for locking in the locking port. The space inside the garlic storage magazine behind the sliding baffle is used to store garlic seeds. The lower part of the push rod is provided with a pressure plate above the garlic magazine fixing box. A vertically arranged connecting rod is connected to the pressure plate. The connecting rod passes through the garlic magazine fixing box and its bottom is connected to the garlic drop cover. When the pressure plate is pressed down, the garlic drop cover opens.

[0007] The rear end of the garlic storage magazine is inserted into the garlic box fixing box through the front opening of the garlic box fixing box. A second through hole for a single garlic seed is opened on the rear wall of the garlic storage magazine, and the axis of the second through hole coincides with that of the first through hole.

[0008] The outer side of the front wall of the garlic box is provided with a fixing buckle, and the outer periphery of the garlic storage magazine is provided with a protruding structure that engages with the fixing buckle.

[0009] The front end of the garlic storage magazine is fitted with a magazine cover, and the front end of the push spring presses against the inside of the magazine cover, while the rear end is fixed to the sliding baffle.

[0010] There are two garlic-falling covers, with their pivots located at the front and rear sides of the bottom of the garlic box fixing body, respectively. There are four connecting rods, each fixed at one of the four corners of the pressure plate. Two connecting rods are located at the front, and the other two at the rear. A spring is fitted onto each connecting rod between the pressure plate and the garlic box fixing body. A guide groove is fixed to the bottom of each connecting rod. The two guide grooves on the front side are inclined downwards from front to back, and the two guide grooves on the rear side are inclined downwards from back to front. Horizontally arranged sliding rods extending left and right are fixedly connected to the bottom surfaces of the two garlic-falling covers. The two ends of the sliding rod on the front side are slidably fitted into the two guide grooves on the front side, and the two ends of the sliding rod on the rear side are slidably fitted into the two guide grooves on the rear side. A sleeve is fixed to the push rod above the pressure plate. A clamping block for fixing the connecting rod is provided on the pressure plate. When the push rod moves downwards, the sleeve presses down on the pressure plate, the connecting rod moves downwards, the sliding rod moves within the guide groove, and the garlic-falling cover opens.

[0011] The ball head has an ellipsoidal structure, and there is a smooth transition between the ball head and the push rod.

[0012] The front side of the frame is provided with a lifting frame, and the garlic box fixing box is fixed to the lower part of the lifting frame. The upper part of the lifting frame is provided with rotating support seats for installing transmission rods on both sides. The bottom left and right sides of the lifting frame are fixedly connected with guide rod bases. Each guide rod base is equipped with a vertically upward guide rod. The left and right sides of the frame are fixed with forward-extending fixing rods. Each fixing rod is provided with a guide sleeve for the guide rod to pass through upward. The guide sleeve is located above the guide rod base.

[0013] The plow in front of the cart includes a comb-shaped plow frame and a plow that is evenly spaced on the left and right sides and fixed on the plow frame. Each fixed rod is fixedly connected to a vertically arranged connecting rod, and the left and right sides of the plow frame are fixedly connected to two connecting rods respectively.

[0014] The rear end of the frame is equipped with a leveling rake, with the teeth of the leveling rake facing downwards.

[0015] The frame is equipped with a chain tensioning mechanism, which includes an arc-shaped adjusting seat and a tensioning sprocket. The tensioning sprocket is used to tension the chain between the driven sprocket and the driving sprocket. The arc-shaped adjusting seat has adjusting holes distributed in an arc shape. A connecting shaft is fixed at the center of the tensioning sprocket and is installed in the adjusting holes.

[0016] The beneficial effects of this utility model are: the rotation of the front wheel axle drives the cam to rotate, thereby driving the push rod to move up and down. In other words, the power for the push rod to move up and down is provided by the vehicle drive mechanism. Under the drive mechanism, the push rod moves up and down in the garlic box, continuously pushing out the garlic seeds in the garlic storage magazine. Garlic cloves are arranged in a straight line with their buds facing upwards in the garlic storage magazine. A spring pushes a sliding baffle to move the garlic cloves along the internal channel of the magazine towards the magazine's fixed chamber. As the push rod moves downwards, the ball end at its lower end pushes the garlic cloves downwards, and the garlic drop cover opens, allowing the cloves to fall. After the cloves have fallen, the cam rotates and returns to its original position. The push rod moves upwards under the action of the return spring. At this point, the garlic outlet of the magazine is blocked by the ball end of the push rod, preventing the cloves from entering the fixed chamber. The garlic drop cover closes. Once the push rod moves upwards and no longer blocks the garlic outlet, the next clove is pushed into the fixed chamber, completing one garlic planting cycle. The garlic seed planting speed can be controlled by the rotation speed of the vehicle drive mechanism and the transmission ratio of the chain drive. The garlic magazine push device adopts an array arrangement, which enables the whole machine to plant multiple rows and columns of garlic at the same time, improving work efficiency, improving the consistency of planting spacing, and effectively solving the problem that the walking speed of the seeder cannot be greatly increased and the spacing is inconsistent due to the inconsistent adjustment time of scale buds between different rows.

[0017] Preferably, the garlic storage magazine is installed on the garlic magazine fixing box, and the end of the garlic storage magazine connected to the garlic magazine fixing box is designed with a fixing structure that cooperates with the garlic magazine fixing box, forming a plug-in structure, which can realize the quick insertion and removal of the garlic storage magazine.

[0018] Preferably, when the garlic dropper cover is closed, the garlic cloves cannot fall out from the bottom of the garlic box (i.e., ensuring that the garlic cloves will not fall out due to vehicle vibration, etc.). When the garlic dropper cover is open, the garlic cloves fall out from the bottom of the garlic box. The specific principle of opening and closing the garlic dropper cover is as follows: the pressure sleeve is fixed on the push rod, which strikes the pressure plate, forcing it to move downward. The connecting rod follows the pressure plate downward, and the sliding rod moves obliquely upward in the guide groove, causing the garlic dropper cover to open. When the push rod moves upward, the pressure sleeve separates from the large push rod, the spring pushes the pressure plate upward, and the connecting rod follows the pressure plate upward. The sliding rod moves obliquely downward in the guide groove, causing the garlic dropper cover to open. When the pressure plate moves downward, the spring is compressed. When the pressure plate is not under the action of the pressure sleeve, it pushes the pressure plate upward. The connecting rod follows the pressure plate upward, causing the garlic dropper cover to close.

[0019] Preferably, the garlic storage magazine and the garlic magazine fixing box are fixed on the lifting frame. The lifting frame can be connected to the vehicle frame through a slide rail. When planting, the lifting frame is lowered to make it close to the ground, reducing the falling distance of the garlic seeds and improving the budding efficiency. When changing the garlic storage magazine or loading garlic seeds, the lifting frame is raised to facilitate the disassembly and assembly of the garlic storage magazine. The guide rod plays a guiding role in the up and down movement of the lifting frame.

[0020] Preferably, at the front end of the vehicle frame, there are soil trenching plows arranged in a horizontal array with spacing corresponding to the magazine pushing structure on the lifting frame. When the vehicle is moving, the plows push the soil to form planting troughs with intervals, ensuring that the garlic seeds can fall into the corresponding soil troughs. At the rear end of the vehicle frame, there is a rake-type structure for leveling the soil and burying the garlic seeds.

[0021] Preferably, when the lifting frame is rising and falling, the transmission chain is prone to loosening. By adopting a tension adjustment structure, the tension of the transmission chain can be adjusted when the lifting frame is in different positions to ensure transmission efficiency.

[0043] like Figures 7 to 11 As shown, the planting mechanism 5 includes a garlic storage magazine 5.1 and a garlic magazine fixing box 5.2. The garlic magazine fixing box 5.2 has a vertically arranged first through hole 5.21 inside. The ball head 4.9 is used to insert into the first through hole 5.21. The diameter of the first through hole 5.21 is larger than the cross-sectional diameter of a single garlic seed but smaller than the sum of the cross-sectional diameters of two garlic seeds. A garlic drop cover 5.23 is rotatably mounted on the bottom surface of the garlic magazine fixing box 5.2. The front side of the garlic magazine fixing box 5.2 has a front opening communicating with the first through hole 5.21, forming a three-way structure with the first through hole 5.21. Figures 12 to 14 As shown.

[0044] The garlic storage magazine 5.1 adopts a cylindrical structure with its axis perpendicular to the front wheel axle 2 and horizontally arranged. The rear of the garlic storage magazine 5.1 is connected to the front opening of the garlic magazine fixing box 5.2. The garlic storage magazine 5.1 has a sliding baffle 5.11 inside, and a push spring 5.12 is provided between the sliding baffle 5.11 and the front end of the garlic storage magazine. The push spring 5.12 is used to push the sliding baffle 5.11 to move backward. The wall of the garlic storage magazine 5.1 has a sliding groove 5.13 extending along the axial direction of the garlic storage magazine, and the front of the sliding groove 5.13 has a locking opening 5.14. The sliding baffle 5.11 is connected to a handle 5.15 for engaging with the engagement slot 5.14. The space behind the sliding baffle 5.11 in the garlic storage magazine 5.1 is used to store garlic seeds. The lower part of the push rod 4.5 is provided with a pressure plate 5.24 above the garlic magazine fixing box 5.2. A vertically arranged connecting rod 5.25 is connected to the pressure plate 5.24. The connecting rod 5.25 passes through the garlic magazine fixing box 5.2 and its bottom is connected to the garlic drop cover 5.23. When the pressure plate 5.24 is pressed down, the garlic drop cover 5.23 opens.

[0045] like Figures 15 to 16 As shown, the rear end of the garlic storage magazine 5.1 is inserted into the garlic magazine fixing box 5.2 through an opening on the front side of the garlic magazine fixing box. A second through hole 5.16 for a single garlic clove to pass through is provided on the rear wall of the garlic storage magazine 5.1, and the axis of the second through hole 5.16 coincides with that of the first through hole 5.21. A fixing buckle 5.22 is provided on the outer side of the front wall of the garlic magazine fixing box 5.2, and a protruding structure 5.17 that engages with the fixing buckle 5.22 is provided on the outer periphery of the garlic storage magazine 5.1. A magazine cover is installed at the front end of the garlic storage magazine 5.1, and the front end of the push spring presses against the inner side of the magazine cover, while the rear end is fixed to the sliding baffle 5.11.

[0046] There are two garlic-dropping covers 5.23, with their pivots located at the front and rear sides of the bottom of the garlic box fixing housing, respectively. There are four connecting rods 5.25, fixed at the four corners of the pressure plate 5.24. Two connecting rods 5.25 are located at the front, and the remaining two at the rear. A spring (not shown in the attached diagram) is fitted onto each connecting rod 5.25 between the pressure plate 5.24 and the garlic box fixing housing 5.24. A guide groove is fixed to the bottom end of each connecting rod 5.25. 5.26, the two guide grooves 5.26 on the front side are inclined downwards from front to back, and the two guide grooves 5.26 on the rear side are inclined downwards from back to front. Horizontally arranged sliding rods 5.27 extending left and right are fixedly connected to the bottom surfaces of the two garlic-dropping covers 5.23. The two ends of the sliding rods 5.27 on the front side are slidably fitted into the two guide grooves 5.26 on the front side, and the two ends of the sliding rods 5.27 on the rear side are slidably fitted into the two guide grooves 5.26 on the rear side. A pressure sleeve 4.11 is fixed on the push rod 4.5 above the pressure plate 5.24. The pressure plate 5.24 is provided with a clamping block 5.28 for fixing the connecting rod 5.25. When the push rod 4.5 moves downwards, the pressure sleeve 4.11 presses down on the pressure plate 5.24, the connecting rod 5.25 moves downwards, the sliding rods 5.27 move within the guide grooves 5.26, and the garlic-dropping covers 5.23 open.

[0047] like Figure 17 As shown, the front side of the frame 1 is provided with a lifting frame 6, and the garlic box fixing box 5.2 is fixed to the lower part of the lifting frame 6. The upper part of the lifting frame 6 is provided with rotating support seats 6.1 for installing transmission rods 4.1 on both sides. The bottom left and right sides of the lifting frame 6 are fixedly connected with guide rod bases 6.4. Each guide rod base is equipped with a vertically upward guide rod 6.2. The left and right sides of the frame 1 are fixed with forward-extending fixing rods 1.1. Each fixing rod 1.1 is provided with a guide sleeve 6.3 for the guide rod 6.2 to pass through upward. The guide sleeve 6.3 is located above the guide rod base 6.4.

[0048] The plow 7 includes a comb-shaped plow frame 7.1 and plows 7.2 that are evenly spaced on the left and right sides of the plow frame 7.1. Each fixed rod 1.1 is fixedly connected to a vertically arranged connecting rod 1.2, and the left and right sides of the plow frame 7.1 are fixedly connected to two connecting rods 1.2 respectively. The rear end of the frame 1 is provided with a leveling rake 8, with the teeth of the leveling rake 8 facing downwards.

[0049] like Figure 18As shown, the frame 1 is equipped with a chain tensioning mechanism 9, which includes an arc-shaped adjusting seat 9.1 and a tensioning sprocket 9.2. The tensioning sprocket 9.2 is used to tension the chain between the driven sprocket 4.3 and the driving sprocket 4.2. The arc-shaped adjusting seat 9.1 has adjusting holes distributed in an arc shape. A connecting shaft 9.3 is fixed at the center of the tensioning sprocket 9.2 and is installed in the adjusting holes.

[0050] like Figure 1 As shown, the front plow 7, wheels, and leveling rake 8 are all fixed to the frame 1. The plows 7.2 in the front plow 7 are in a horizontal array structure, with the spacing between adjacent plows 7.2 being the same as the spacing of the sowing mechanism 5. The front plow 7 has positioning holes, and the height of the plow can be adjusted via the corresponding positioning holes on the connecting rod 1.2 of the frame 1. When the vehicle is moving, the front plow 1 can push the soil apart, forming spaced planting troughs. The rake frame structure 9 is used to level the soil and bury the garlic seeds.

[0051] The garlic box fixing housing 5.2 is fixed on the lifting frame 6. The bottom of the garlic box fixing housing 5.2 is equipped with a garlic dropping cover. When the garlic dropping cover is closed, the garlic seeds cannot fall and can only stay in the internal cavity of the garlic box fixing housing 5.2. The opening and closing of the garlic dropping cover is determined by the movement of the push rod. The push rod 4.5 moves up and down reciprocally through the rotation of the cam 4.4. During operation, the garlic storage magazine 5.1, the garlic box fixing housing 5.2, and the push rod 4.5 move in coordination with each other according to their installation positions. The garlic storage magazine 5.1 has a cylindrical structure. The inner diameter of the tube only allows garlic cloves to be arranged in a single row with their scales facing upwards. A vertical second through-hole 5.16 is located at the rear end of the magazine 5.1, allowing a single garlic clove to pass through and exit the magazine. A magazine cover is installed at the front end of the magazine 5.1, containing a sliding baffle. A push spring 5.12 is located between the magazine cover and the sliding baffle. When a single garlic clove is inside the magazine 5.1, the push spring 5.12 pushes the sliding baffle 5.11 to move, pushing... The garlic seed moves along the internal channel of the garlic storage magazine 5.1 towards the garlic magazine fixing box 5.2, and enters the internal cavity of the garlic magazine fixing box 5.2. The push rod 4.5 moves downward, and the ball head 4.9 at the lower end of the push rod pushes the garlic seed downward. At the same time, the pressure sleeve 4.11 on the push rod 4.5 presses the pressure plate 5.24 downward. The relative position of the pressure plate 5.24 and the connecting rod 5.25 is fixed by the clamping block 5.28. The connecting rod 5.25 moves downward, the garlic drop cover 5.23 opens, and the garlic seed falls. After the garlic seed is dropped, the cam 4.4 rotates and enters the return stroke. The push rod 4.5 moves upward under the action of the return spring 4.8. At this time, the garlic outlet of the garlic storage magazine 5.1 is blocked by the ball head 4.9 of the push rod, and the garlic seed cannot enter the inner cavity of the garlic magazine fixing box 5.2. At the same time, as the push rod 4.5 moves upward, the pressure plate 5.24 is no longer under pressure. Under the action of the spring between the pressure plate 5.24 and the garlic magazine fixing box 5.2, it resets upward, driving the connecting rod 5.25 to move upward. The garlic dropping cover 5.23 closes. After the push rod 4.5 moves upward until it no longer blocks the garlic outlet of the garlic storage magazine 5.1, the next garlic seed is pushed into the inner cavity of the garlic magazine fixing box 5.2, completing one garlic seed planting cycle.

[0052] The function of the garlic drop cover is: when it is closed, the garlic cloves cannot fall out from the bottom of the garlic box (that is, to ensure that the garlic cloves will not fall out due to vehicle vibration or other reasons); when it is open, the garlic cloves fall out from the bottom of the garlic box. The principle of the garlic-falling cover opening and closing is as follows: The pressure sleeve 4.11 is fixed on the push rod 4.5, which strikes the pressure plate 5.24, forcing it to move downward. The connecting rod 5.25 follows the pressure plate 5.24 downward, and the sliding rod 5.27 moves obliquely upward in the guide groove 5.26, causing the garlic-falling cover 5.23 to open. When the push rod 4.5 moves upward, the pressure sleeve 4.11 separates from the push rod 4.5, and the spring pushes the pressure plate 5.24 upward. The connecting rod 5.25 follows the pressure plate 5.24 upward, and the sliding rod 5.27 moves obliquely downward in the guide groove 5.26, causing the garlic-falling cover 5.23 to open. The spring is compressed when the pressure plate 5.24 moves downward. When the pressure plate 5.24 is not under the action of the pressure sleeve 4.11, it pushes the pressure plate 5.24 upward. The connecting rod 5.25 follows the pressure plate 5.24 upward, causing the garlic-falling cover 5.23 to close.

[0053] The planting mechanism employs a magazine-driven structure, arranged in an array, allowing for the simultaneous planting of multiple rows and columns of garlic in one go, thus improving work efficiency and the uniformity of planting spacing. The end connecting the garlic storage magazine 5.1 to the garlic magazine fixing box 5.2 is designed with a fixing structure that cooperates with the garlic magazine fixing box 5.2, forming an insert-type structure. This allows for quick insertion and removal of the garlic storage magazine 5.1, enabling rapid loading of garlic seeds.

[0054] The garlic box fixing housing 5.2 and the push rod 4.5 are fixed on the same lifting frame. The interior of the garlic box fixing housing 5.2 has a three-way structure. The diameter of the end structure of the push rod 4.5 matches the diameter of the first through hole 5.21 of the garlic box fixing housing 5.2. The push rod 4.5 can reciprocate inside the garlic box fixing housing 5.2. The reciprocating stroke and speed of the push rod 4.5 are adjusted by the shape of the cam. The speed of the cam rotation can be adjusted by adjusting the transmission ratio of the chain drive, thus controlling the reciprocating speed of the push rod. The push stroke (downward movement) and return stroke (upward movement) of the push rod 4.5 pass through the second through hole of the garlic storage magazine 5.1. The size of the second through hole only allows a single garlic clove to pass through.

[0055] The lifting frame 6 is connected to the frame 1 via a slide rail. The transmission rod 4.1 is mounted on the frame 1 via a rotating support 6.1. Guide rods 6.2 are provided on both sides of the lifting frame 6. When the height of the lifting frame 6 is adjusted on the frame 1, the guide rods 6.2 move up and down within the guide sleeves 6.3, thereby constraining the up and down movement of the lifting frame 6. When the seeder is performing sowing operations, the lifting frame is lowered, and the garlic falls close to the ground, reducing the distance the garlic seeds fall and improving the budding efficiency. When it is necessary to refill the garlic seed storage magazine 5.2 or replace the garlic seed storage magazine 5.2, the lifting frame is raised for easy operation. The transmission rod 4.1 is rotatably mounted on the lifting frame 6, and the cams 4.4 are arrayed on the transmission rod 4.1. The drive sprocket drives the transmission rod 4.1 and the cams 4.4 to rotate, providing power for the up and down movement of the guide rods 6.3.
