Description

Technical Field

[0001] This invention relates to an electrically driven array-type garlic sprouting planter, belonging to the field of agricultural machinery technology. Background Technology

[0002] Garlic, as a condiment in daily life, has a large demand, and its planting area is increasing year by year. Manual garlic cultivation is labor-intensive and inefficient, making mechanized cultivation an inevitable trend. Garlic planting requires correct bud alignment, but most garlic planters on the market lack bud adjustment functions or have low bud alignment rates. Although a few garlic planters have bud adjustment functions, their operating efficiency is low.

[0003] The main reasons for the low operating efficiency of garlic planters with scale and bud adjustment function are: (1) Due to the large individual differences in garlic, the adjustment time of scale and bud orientation is inconsistent, especially for garlic seeds with inconsistent initial scale and bud orientation. In order to ensure consistent row spacing after planting, they can only wait for the garlic seeds with slower scale and bud adjustment to finish adjusting before planting together. This results in a very slow planting speed of the planter, which in turn limits the forward speed of the whole machine; (2) In order to ensure the qualified rate of single seed picking, the seed picking speed of the single seed picking device is low; (3) In order to ensure the uprightness rate of planting, the vertical movement speed of the planting device is low. Due to the constraints of the above problems, the garlic planter has a low moving speed and it is difficult to improve the operating efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an electrically driven array-type garlic bud-propagating planter to solve the technical problem of low operating efficiency of existing garlic planters.

[0005] This invention adopts the following technical solution: an electrically driven array-type garlic sprouting planter, comprising a main frame, on which drive wheels, driven wheels, a drive motor, and a control box are mounted. The drive motor operates under the control of the control box, and the drive wheels rotate under the drive of the drive motor. There are two drive wheels and two driven wheels. The main frame is provided with a planting device and a seed-collecting device located above the planting device. The seed-collecting device includes a seed-collecting box, which contains a seed-collecting chain, a limiting guide plate, and garlic seed guide tubes. The garlic seed guide tubes are vertically arranged and have openings at both the top and bottom. The garlic seed guide tubes are distributed in a rectangular array inside the seed-collecting box, and the bottom of the garlic seed guide tubes passes through the bottom plate of the seed-collecting box. The upper and lower parts of the seed-collecting box... The system is equipped with parallel upper and lower axles, both perpendicular to the axis of the driven wheel. The number of upper and lower axles is equal, and they correspond one-to-one. The upper axle is positioned above the top of the garlic seed guide tube and to one side of it, while the lower axle is positioned close to the bottom of the seed collection box. The number of upper and lower axles is equal to the number of rows in the garlic seed guide tube. Each pair of corresponding upper and lower axles is connected to a seed collection chain via a seed collection chain sprocket, with a chain number equal to the number of rows in the garlic seed guide tube. The seed collection chain is equipped with elastic seed collection claws. Each elastic seed collection claw consists of a mounting plate connected together and an elastic claw with a conical, bowl-shaped structure. The mounting plate is fixedly connected to the seed collection chain, and the elastic claw is used to grasp individual garlic cloves.

[0006] The planting device includes an upper fixed frame and a planting cylinder mounting base arranged at intervals. The upper fixed frame is fixedly connected to the bottom of the seed box via a vertical connecting rod. The planting cylinder mounting base is fixedly installed with planting cylinders arranged in an array. The number of rows and columns of the planting cylinders is equal to the number of rows and columns of the garlic seed guide tube. Both the upper and lower ends of the planting cylinders are open structures, and the lower end of the planting cylinder has a pointed tip for inserting into the soil. A horizontally arranged power output shaft perpendicular to the axis of the driven wheel is rotatably mounted on the upper fixed frame. The middle part of the power output shaft is a gate-shaped protrusion structure. A crank is movably connected to the protrusion structure. A vertically arranged connecting rod is movably connected below the crank. The lower end of the connecting rod is connected to the planting cylinder mounting base. When the power output shaft rotates, it drives the planting cylinder mounting base to move up and down through the crank and the connecting rod. A guide mechanism is connected between the upper fixed frame and the planting cylinder mounting base to guide the up and down movement of the planting cylinder mounting base.

[0007] The upper fixed frame is connected to an opening and closing cone mechanism, which includes a cone mounting frame and opening and closing cones mounted on the cone mounting frame. The opening and closing cones are arranged in an array, and the number of rows and columns of the opening and closing cones is equal to the number of rows and columns of the garlic seed guide tube. Each opening and closing cone is located above each planting cylinder. Each opening and closing cone is a cone-shaped structure with an open top and a gradually narrowing bottom. Each opening and closing cone is formed by two half cones joined together. Each half cone has a shaft hole and a connecting ear located below the shaft hole on its outer side. The cone mounting frame is provided with a cone mounting shaft arranged parallel to the power output shaft. Each half cone is mounted on the cone mounting shaft through the shaft hole. A spring is installed in the shaft hole. Under the action of the spring force, the two half cones are joined together to form an opening and closing cone. A cone opening and closing control line is connected between the planting cylinder mounting seat and the connecting ear of the half cone. When the planting cylinder mounting seat moves down, it drives the opening and closing cone to open.

[0008] Between the upper fixed frame and the seed box, there are scale bud orientation adjustment tubes equal in number to the garlic seed guide tubes. The inner side of the scale bud orientation adjustment tube has serrated protrusions. The upper end of each scale bud orientation adjustment tube is fixedly connected to the lower end of the garlic seed guide tube. Each scale bud orientation adjustment tube is set obliquely and the lower end of each scale bud orientation adjustment tube is located directly above each opening and closing cone.

[0009] The main frame is equipped with a power commutator. The input end of the power commutator is connected to the shaft of the driven wheel through a first transmission mechanism, and the output end of the power commutator is connected to the power output shaft. When the driven wheel shaft rotates, the power output shaft will be driven to rotate through the power commutator.

[0010] The seed collection box is equipped with a seed collection chain transmission mechanism that drives the seed collection chain to rotate. The seed collection chain transmission mechanism is connected to the power output shaft, and the rotation of the power output shaft drives the seed collection chain.

[0011] The first transmission mechanism includes a power transmission chain and a power transmission sprocket mounted on the driven wheel connecting shaft. The power transmission chain meshes with the power transmission sprocket and the sprocket on the power commutator to transmit power from the driven wheel connecting shaft to the power commutator.

[0012] The seed-collecting chain transmission mechanism includes a seed-collecting device transmission chain, a drive sprocket, and several seed-collecting drive sprockets. The drive sprocket is installed at the end of the power output shaft away from the power commutator. The number of seed-collecting drive sprockets is greater than the number of upper wheel shafts. All seed-collecting drive sprockets are located outside the housing. A portion of the seed-collecting drive sprockets are connected to the upper wheel shafts to drive each upper wheel shaft to rotate. The remaining seed-collecting drive sprockets are rotated and mounted on the housing. The seed-collecting device transmission chain is wound around the drive sprocket and each seed-collecting drive sprocket in sequence, and is driven by the drive sprocket.

[0013] A power output shaft mounting base is fixedly connected to the part of the upper fixed frame located below the housing and protruding from the outside of the housing. The end of the power output shaft away from the power commutator is connected to the power output shaft mounting base.

[0014] The guiding mechanism includes a vertically arranged guide rod and guide bearing seats connected to the upper and lower ends of the guide rod. The upper and lower guide bearing seats are respectively installed on the upper fixed frame and the insert cylinder mounting base. The upper and lower ends of the guide rod slide through the upper and lower guide bearing seats respectively.

[0015] The seed collection box is equipped with a limiting guide plate spaced apart from the upper wheel axle. Each seed collection chain has a limiting guide plate on both sides. The bottom of the limiting guide plate is fixedly connected to the bottom of the seed collection box. Both the upper and lower wheel axles pass through the limiting guide plate.

[0016] The cone-shaped mounting frame is connected to the lower part of the upper fixed frame. A seed-dropping connecting plate is fixedly connected to the upper fixed frame above the cone-shaped mounting frame. The seed-dropping connecting plate has openings corresponding to each opening and closing cone. Each opening is located directly above each opening and closing cone. The lower end of the scale bud facing the adjustment tube is connected to the opening of the seed-dropping connecting plate.

[0017] The bud orientation adjustment tube includes an upper section, a middle section, and a lower section connected together. The middle section is an inclined tube section, and the serrated protrusion is located inside the inclined tube section. The upper and lower sections are both vertical tube sections. The upper section is connected to the garlic seed guide tube, and the lower section is located above the opening and closing cone.

[0018] The main frame is equipped with a power supply assembly connected to the control box. The power supply assembly is fixed to the top of the control box, and a wireless receiving module is installed inside the control box.

[0019] The driven wheel is the front wheel, the driving wheel is the rear wheel, the control box is installed at the front end of the main frame, and the seed-collecting chain transmission mechanism is located at the rear side of the seed-collecting box.

[0020] The beneficial effects of this invention are as follows: This invention drives the drive wheel to rotate via a drive motor, thereby driving the whole machine forward. When the driven wheel rotates, it drives the driven wheel connecting shaft to rotate, thereby driving the power transmission chain. The power transmission chain transmits power to the power commutator, and after the power is reversed, it transmits power to the power output shaft. The rotation of the power output shaft provides power to the seed taking device and the planting device. When the power output shaft rotates, it drives the seed-collecting device's transmission chain, causing the upper wheel shaft inside the seed-collecting box to rotate. This, in turn, drives the seed-collecting chain, which in turn drives the elastic seed-collecting claws. The elastic seed-collecting claws grab the garlic seeds from the seed-collecting box and, driven by the seed-collecting chain, rise in position. When they reach the upper end of the garlic seed guide tube, they are released into the guide tube under pressure. After falling into the guide tube, the garlic seeds are oriented towards the adjusting tube and then fall into the opening and closing cone. The opening and closing cone opens and then descends into the planting cylinder of the planting device. When the power output shaft rotates, it simultaneously drives the crank and connecting rod. The crank and connecting rod move the planting cylinder mounting base up and down, and the planting cylinder also moves up and down. When the planting cylinder moves downward, it inserts into the soil. At the same time, the opening and closing cone is opened using the cone opening and closing control line, allowing the garlic seeds to enter the soil and completing the planting process. An opening and closing cone is installed above the planting cylinder. When the planting cylinder mounting base moves down, the cone opening and closing control line is pulled down to tighten it. The cone opening and closing control line pulls the opening and closing cone open, so that the garlic seed can fall into the planting cylinder from the opening and closing cone.

[0021] The array-type planter provided by this invention can simultaneously plant multiple rows and columns of garlic, which can significantly improve work efficiency, effectively improve the consistency of planting spacing, and effectively solve the problems of the planter's walking speed not being able to be greatly increased and the plant spacing being inconsistent due to the inconsistent adjustment time of scale buds between different rows.

Detailed Implementation

[0035] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0036] An embodiment of the present invention discloses an electrically driven array-type garlic sprouting planter, comprising a main frame 13, on which drive wheels 9, driven wheels 1, a drive motor 10, and a control box 3 are mounted. The drive motor operates under the control of the control box 3, and the drive wheels 9 rotate under the drive of the drive motor 10. There are two drive wheels 9 and two driven wheels 1, with the driven wheels 1 being the front wheels and the drive wheels 9 being the rear wheels. The control box 3 is mounted at the front end of the main frame 13, and a power supply assembly 2 connected to the control box 3 is provided on the main frame 13. The power supply assembly 2 is fixed to the top of the control box 3, and a wireless receiving module is provided inside the control box 3. Figure 1 As shown, the power supply assembly 2 and the control box 3 are installed on the front upper part of the main frame 13, providing power and motion control for the two drive wheels 9. The movement of the whole machine can be controlled by the remote control handle and the wireless receiving module in the control box 3.

[0037] The main frame 13 is equipped with a planting device 8 and a seed-collecting device 7 located above the planting device 8. The seed-collecting device 7 includes a seed-collecting box, which contains a seed-collecting chain 708, a limiting guide plate 703, and garlic seed guide tubes 705. The garlic seed guide tubes 705 are vertically arranged and have openings at both the top and bottom. The garlic seed guide tubes 705 are arranged in a rectangular array inside the seed-collecting box, and their bottoms pass through the bottom plate of the seed-collecting box. The upper and lower parts of the seed-collecting box are respectively equipped with parallel upper wheel axles 704 and lower wheel axles 710. The axes of the upper wheel axles 704 and lower wheel axles 710 are perpendicular to the axis of the driven wheel 1. The number of upper wheel axles 704 and lower wheel axles 710 is equal. In a one-to-one correspondence, the upper wheel axle 704 is installed higher than the upper end of the garlic seed guide tube 705 and located on one side of the garlic seed guide tube 705, while the lower wheel axle 710 is located close to the bottom surface of the seed collection box. The number of upper wheel axles 704 and lower wheel axles 710 is equal to the number of rows of garlic seed guide tubes 705. Each pair of upper wheel axles 704 and lower wheel axles 710 is connected to a seed collection chain 708 with the same number of rows as the garlic seed guide tubes 705 via a seed collection chain sprocket 706. The seed collection chain 708 is equipped with an elastic seed collection claw 707. The elastic seed collection claw 707 includes a mounting plate connected together and an elastic claw with a conical bowl-shaped structure. The mounting plate is fixedly connected to the seed collection chain, and the elastic claw is used to grab a single garlic clove.

[0038] The seed collection box is provided with spaced-out limiting guide plates 703. Each seed collection chain 708 has a limiting guide plate 703 on both sides. The bottom of the limiting guide plate 703 is fixedly connected to the bottom of the seed collection box. The upper wheel axle 704 and the lower wheel axle 710 both pass through the limiting guide plate 703.

[0039] The planting device 8 includes an upper fixed frame 802 and a planting cylinder mounting base 811 arranged at intervals. The upper fixed frame 802 is fixedly connected to the bottom of the seed box by a vertical connecting rod. The planting cylinder mounting base 811 is fixedly installed with planting cylinders 810 arranged in an array. The number of rows and columns of the planting cylinders 810 is equal to the number of rows and columns of the garlic seed guide tube 705. Both the upper and lower ends of the planting cylinders 810 are open structures, and the lower end of the planting cylinder 810 has a pointed tip for inserting into the soil. A horizontally arranged power output shaft 6 perpendicular to the axis of the driven wheel 1 is rotatably mounted on the upper fixed frame 802. The middle part of the power output shaft 6 is a gate-shaped protrusion structure, and a crank 805 is movably connected to the protrusion structure. A vertically arranged connecting rod 806 is movably connected below 805. The lower end of the connecting rod 806 is connected to the insert mounting base 811. When the power output shaft 6 rotates, it drives the insert mounting base 811 to move up and down through the crank 805 and the connecting rod 806. A guide mechanism is connected between the upper fixed frame 802 and the insert mounting base 811 to guide the up and down movement of the insert mounting base 811. The guide mechanism includes a vertically arranged guide rod 803 and guide bearing seats 804 connected to the upper and lower ends of the guide rod. The upper and lower guide bearing seats are respectively installed on the upper fixed frame 802 and the insert mounting base 811. The upper and lower ends of the guide rod 803 slide through the upper and lower guide bearing seats 804 respectively.

[0040] The upper fixed frame 802 is connected to an opening and closing cone mechanism, which includes a cone mounting frame 807 and opening and closing cones 809 mounted on the cone mounting frame 807. The opening and closing cones 809 are arranged in an array, and the number of rows and columns of the opening and closing cones 809 is equal to the number of rows and columns of the garlic seed guide tube 704. Each opening and closing cone 809 is located above each planting cylinder 810. Each opening and closing cone 809 is a cone-shaped structure with an open top and a gradually narrowing bottom. Each opening and closing cone 809 is formed by joining two half cones together. Each half cone has a shaft hole on its outer side and a connecting lug located below the shaft hole. The cone mounting frame is provided with a cone mounting shaft 808 arranged parallel to the power output shaft. Each half cone is mounted on the cone mounting frame through the shaft hole. On the mounting shaft 808, a spring is installed in the shaft hole. Under the action of the spring force, two half-cone buckets are joined together to form an opening and closing cone bucket. The cone bucket opening and closing control line 812 is connected between the planting cylinder mounting seat 811 and the connecting ear of the half-cone bucket. When the planting cylinder mounting seat 811 moves down, it drives the opening and closing cone bucket 809 to open. The cone bucket mounting frame 807 is connected to the lower part of the upper fixed frame 802. The upper fixed frame 802 is fixedly connected to the seed dropping connecting plate 801 above the cone bucket mounting frame 807. The seed dropping connecting plate 801 has openings corresponding to each opening and closing cone bucket 809. Each opening is located directly above each opening and closing cone bucket 809. The lower end of the scale bud facing the adjustment tube 15 is connected to the opening of the seed dropping connecting plate 801.

[0041] Between the upper fixed frame 802 and the seed box, there are bud orientation adjustment tubes 15, the same number as the garlic seed guide tubes 705. The inner side of the bud orientation adjustment tube 15 has serrated protrusions. The upper end of each bud orientation adjustment tube 15 is fixedly connected to the lower end of the garlic seed guide tube 705. Each bud orientation adjustment tube 15 is obliquely arranged and the lower end of each bud orientation adjustment tube is located directly above each opening and closing cone 809. The bud orientation adjustment tube 1 includes an upper section, a middle section and a lower section connected together. The middle section is an obliquely arranged tube section. The serrated protrusions are located inside the oblique tube section. The upper section and the lower section are both vertical tube sections. The upper section is connected to the garlic seed guide tube 705 and the lower section is located above the opening and closing cone 1.

[0042] The main frame 13 is equipped with a power commutator 5. The input end of the power commutator 5 is connected to the driven wheel connecting shaft 11 through a first transmission mechanism, and the output end of the power commutator 5 is connected to the power output shaft 6. When the driven wheel connecting shaft 11 rotates, the power output shaft 6 will be driven to rotate through the power commutator 5. The first transmission mechanism includes a power transmission chain 4 and a power transmission sprocket 12 installed on the driven wheel connecting shaft 11. The power transmission chain 4 meshes with the power transmission sprocket 12 and the sprocket on the power commutator 5 to transmit power from the driven wheel connecting shaft 11 to the power commutator 5.

[0043] The seed collection box is equipped with a seed collection chain transmission mechanism that drives the seed collection chain 708 to rotate. The seed collection chain transmission mechanism is connected to the power output shaft 6, and the rotation of the power output shaft 6 drives the seed collection chain 708. The seed collection chain transmission mechanism is located on the rear side of the seed collection box. The seed collection chain transmission mechanism includes a seed collection device transmission chain 14, a drive sprocket 16, and several seed collection drive sprockets 709. The drive sprocket 16 is installed at the end of the power output shaft 6 away from the power commutator 5. The number of seed collection drive sprockets 709 is greater than the number of upper wheel shafts 704. All seed collection drive sprockets 709 are located outside the box. A portion of the seed collection drive sprockets 709 are connected to the upper wheel shafts 704 to drive each upper wheel shaft to rotate. The remaining seed collection drive sprockets are rotated and mounted on the box. The seed collection device transmission chain 14 is wound around the drive sprocket 16 and each seed collection drive sprocket 709 in sequence, and is driven by the drive sprocket 16. A power output shaft mounting base is fixedly connected to the part of the upper fixed frame 802 located below the housing and protruding from the outside of the housing. The end of the power output shaft 6 away from the power commutator 5 is connected to the power output shaft mounting base.

[0044] The electrically driven array-type garlic sprouting planter provided in this embodiment uses a drive motor to rotate the drive wheel, thereby propelling the entire machine forward. When the driven wheel rotates, it drives the driven wheel connecting shaft to rotate, which in turn drives the power transmission chain. The power transmission chain transmits power to the power commutator (a common component in existing technology that converts horizontal and vertical rotation for easy power transmission). After conversion by the power commutator, the power is transmitted to the power output shaft. When the power output shaft rotates, it drives the seed-collecting device transmission chain, causing the upper wheel shaft inside the seed-collecting box to rotate, thereby driving the seed-collecting chain. The seed-collecting chain, when in motion, drives... The elastic seed-picking claw grasps the garlic cloves from the seed box and, driven by the seed-picking chain, rises to the top of the seed guide tube. Under pressure, it releases the cloves into the guide tube. Once inside, the cloves, oriented towards the adjusting tube, fall into the opening and closing cone. The cone opens, allowing the cloves to descend into the planting cylinder of the planting device. As the power output shaft rotates, it simultaneously drives the crank and connecting rod, which in turn move the planting cylinder mounting base up and down. The planting cylinder itself moves vertically, inserting into the soil as it descends, simultaneously opening the cone and allowing the cloves to fall into the soil, completing the planting process. The opening and closing cone is located above the planting cylinder. When the planting cylinder mounting base moves downwards, it pulls the cone's opening and closing control line, which then opens the cone, allowing the cloves to fall into the planting cylinder.

[0045] This invention provides power to the seed-taking device 7 and the planting device 8 through the rotation of the power output shaft 6. The principle and working process of this invention will be described in detail below with reference to the accompanying drawings:

[0046] like Figure 9 As shown, the seed-collecting device 7 is an array-type single-seed-collecting device. The seed-collecting box of the seed-collecting device 7 includes a seed box frame 701. The seed box frame 701 is welded to the outside of a seed box guard plate 702 to form a box body with an open top. Multiple sets of holes are opened at the upper and lower positions of the front and rear walls of the seed box frame 701. The multiple sets of holes are used to install the upper wheel axle 704 and the lower wheel axle 710. Multiple round holes are arrayed on the seed box guard plate 702 at the bottom of the box body for the installation of garlic seed guide tubes 705. The seed collection box is equipped with multiple limiting guide plates 703 arranged in an array. The limiting guide plates 703 are installed inside the seed box frame 701. A seed collection chain 708 is installed on the inner side of each limiting guide plate 703. The seed collection chain 708 is installed together with the seed collection chain sprocket 706. The seed collection chain sprocket 706 is installed on the upper wheel axle 704 and the lower wheel axle 710 respectively. A seed collection drive sprocket 709 is installed at one end of the upper wheel axle 704 located on the outside of the box. The seed collection drive sprocket 709 is connected to the drive sprocket 16 on the power output shaft 6 through the seed collection device transmission chain 14.

[0047] Each limiting guide plate 703 has a mounting hole at both its upper and lower ends, which are respectively rotatably engaged with the upper wheel axle 704 and the lower wheel axle 710. Each seed-harvesting chain 708 has a limiting guide plate 703 on both its front and rear sides, and the two limiting guide plates 703 are installed opposite each other to form a closed channel. A garlic seed guide tube 705 is installed on the outside of the limiting guide plate 703, and the lower end of the garlic seed guide tube 705 is connected to the scale orientation adjustment tube 15. The seed-collecting chain 708 is uniformly equipped with elastic seed-collecting claws 707. As the elastic seed-collecting claws 707 move upward from the bottom of the seed-collecting box under the drive of the seed-collecting chain 708, the garlic seeds enter the elastic claw part of the elastic seed-collecting claws 707 under the squeezing action of the limiting guide plate 703 and are clamped. They move together with the seed-collecting chain 708 to the top of the seed-collecting box. The garlic seed guide tube 705 comes into contact with the elastic seed-collecting claws 707 and deforms the elastic seed-collecting claws 707. The garlic seeds are ejected from the elastic claws and fall into the garlic seed guide tube 705. Then, the scale bud orientation is adjusted by the scale bud orientation adjustment tube 15, and then the garlic seeds fall into the opening and closing cone 809.

[0048] like Figure 10 As shown, the elastic seed-collecting claw 707 includes a mounting plate and an elastic claw. The mounting plate is rectangular and has two mounting holes for assembly with the seed-collecting chain 708. The elastic claw is shaped like a garlic seed and is a conical bowl-shaped structure made of elastic material with multiple slotted openings at the top. The elastic claw is made of silicone material with high elasticity and certain rigidity, which allows the garlic seed to be clamped and not easily slipped out under external pressure. The elastic seed-collecting claw 707 moves with the seed-collecting chain 708. When passing through the seed-collecting box, the garlic is filled into the elastic claw under the interaction of the garlic seeds. Because the elastic claw is elastic, the volume of the elastic claw can be controlled to ensure that garlic seeds of different sizes are filled into the elastic claw, with only one seed at a time. After the elastic seed-collecting claw 707 moves with the seed-collecting chain 708 to the upper end of the garlic seed guide tube 705, the elastic claw collides with the upper edge of the garlic seed guide tube 705 and achieves seed discharge under deformation and compression. The seed-collecting process of the elastic seed-collecting claw 707 can reduce damage to the garlic. Since minor bumps during the garlic planting process do not affect the germination rate and growth, and studies have shown that squeezing or peeling garlic during planting can advance germination and improve the results, even slight damage to the garlic seed will not affect germination.

[0049] The structure of the bud orientation adjustment tube 15 is as follows: Figure 11As shown, its upper end is connected to the lower end of the garlic seed guide tube 705 of the array-type single-seed extraction device 7, and its lower end is connected to the seed-dropping connecting plate 801 of the array-type planting device 8. The bud orientation adjustment tube is used to adjust the orientation of the garlic seed buds. During the process of the garlic seed falling into the bud orientation adjustment tube 15, there will be an interaction between the slender buds protruding from the head of the seed and the serrated protrusions on the inner side of the bud orientation adjustment tube. When the buds are facing downwards, there is a greater chance that the buds will get stuck in the serrated grooves on the inner side, and the orientation of the buds will be adjusted by the flipping action. The serrated protrusions of the bud orientation adjustment tube 15 can adopt a flexible toothed structure. When the bending angle of the inclined tube section in the bud orientation adjustment tube 15 is in the range of 30-37° and the height of the serrated protrusions is 6-10mm, the bud alignment effect is better.

[0050] like Figures 5 to 8 As shown, the planting device has an array structure, with multiple planting cylinders 810 arranged in a matrix on the planting cylinder mounting base 811. The number of planting cylinders 810 is determined by the number of rows and columns sown at one time. The opening and closing cone 809 of the planting device 8 is connected to the garlic seed guide tube 705 of the seed taking device 7 through the scale bud orientation adjustment tube 15. The opening and closing cone 809 is set above the planting cylinders 810 and is mounted on the cone mounting shaft 808. The opening and closing cone mounting shaft 808 is connected to the cone mounting frame 807. The opening and closing of the cone 809 is controlled by the cone opening and closing control line 812 connected to it. One end of the cone opening and closing control line 812 is connected to the lug on the cone 809, and the other end is connected to the planting cylinder mounting base 811. When the planting cylinder mounting base 811 moves downward to drive the planting cylinder 809 to be inserted into the soil to a set depth, the cone opening and closing control line 812 pulls the cone 809 open, and the garlic seed falls out of the cone 809, completing the planting of the garlic seed.

[0051] like Figure 12 As shown, the opening and closing conical bucket 809 consists of two parts, left and right. Each part has an integrally formed shaft hole at its upper end, and a spring connects the shaft hole to the conical bucket mounting shaft 808. Each part of the opening and closing conical bucket has a support lug at its lower end, which connects to the conical bucket opening and closing control line 812. Under normal conditions, the two parts of the opening and closing conical bucket are closed under the action of the spring. When the inserting cylinder mounting base 811 moves downwards a certain distance, the two parts of the opening and closing conical bucket 809 open under the tension of the conical bucket opening and closing control line 812.

[0052] The planting cylinder mounting base 812 is connected to the connecting rod 806 and the crank 805 to form a crank-connecting rod reciprocating motion structure, driving the mounting base 811 to reciprocate up and down, and simultaneously driving the planting cylinder 810 to reciprocate up and down for planting. The crank 805 is movably connected to the protruding structure in the middle of the power output shaft 6. The power output shaft 6 rotates to drive the entire crank-connecting rod structure, thus realizing the up and down reciprocating motion of the planting cylinder 810. The planting cylinder mounting base 811 is connected to the upper fixed frame 802 via guide rods 803 and guide bearing seats 804. Four guide bearing seats 804 are installed at the four corners of the upper fixed frame 802, and another four guide bearing seats 804 are installed on the planting cylinder mounting base 811. The four guide rods 803 are respectively installed in the corresponding upper and lower guide bearing seats 804.

[0053] Using the above solution, the array-type planter can simultaneously plant multiple rows and columns of garlic, which can significantly improve work efficiency, effectively improve the consistency of planting spacing, and effectively solve the problems of the planter's walking speed not being able to be greatly increased and the plant spacing being inconsistent due to the inconsistent adjustment time of scale buds between different rows.

[0054] Of course, the above description is not limited to the examples above.
