Description

Technical Field

[0001] This invention relates to the field of Chinese yam planting machine technology, and in particular to a Chinese yam planting machine. Background Technology

[0002] Chinese yam, a perennial twining herbaceous plant belonging to the Dioscoreaceae family and the Dioscorea genus, has fleshy, thick, slightly cylindrical underground tubers that grow vertically. Its stems are mostly purple, slender, ridged, and smooth. Leaves are opposite or whorled in groups of three, with leaf blades ranging from triangular-ovate to broadly triangular-ovate. It has small, yellowish-green flowers in spike-like inflorescences and bears three-angled winged fruits. It flowers in autumn (July-August) and fruits in October. It has excellent edible and medicinal value and is a good economic crop.

[0003] However, the current planting operations are all done manually, with a low degree of automation, which will affect production efficiency and lead to higher production costs. In addition, manual planting will also result in the appearance of Chinese yam not being very standardized and uniform.

[0004] This case is proposed to address or improve upon the shortcomings or deficiencies of existing technologies. Summary of the Invention

[0005] The technical problem solved by this invention is achieved by the following technical solution, which includes the following mechanism;

[0006] The supporting moving mechanism includes a chassis frame and four moving wheels rotatably mounted on the chassis frame, wherein the two moving wheels on the front side are driven by a chassis-only drive motor, and the chassis-only drive motor and the moving wheels are driven by a sprocket transmission structure.

[0007] The planting drilling mechanism includes a drilling frame fixed on the chassis frame and a sliding platform frame slidably mounted on the drilling frame. A drilling screw and a drilling drive motor for driving the drilling screw are rotatably mounted on the sliding platform frame. The drilling drive motor and the drilling screw are driven by a sprocket transmission structure. Fixed pulleys are provided at the bottom and top of the drilling frame. A synchronous belt connected between the fixed pulleys is driven by a height drive motor. The sliding platform frame is fixedly connected to one side of the synchronous belt, thereby allowing the sliding platform frame to move up and down under the drive of the synchronous belt.

[0008] The straw bundling and burying mechanism for a Chinese yam planting machine includes a structural frame constructed from aluminum alloy profiles and fastening bolts. Two sets of symmetrical straw bins are fixed to the structural frame via bolts. The space between each set of straw bins is used to store bundled straw. A driven shaft is rotatably mounted on the structural frame via bearings. U-shaped notch discs are fixed at intervals between the driven shafts. The U-shaped notches on the notches allow individual straw bundles to fall into them when facing upwards. A straw clamping frame is located below the structural frame to receive individual straw bundles falling from the rotating U-shaped notch discs. A hinged multi-bar mechanism is also mounted on the structural frame. This mechanism is driven by a motor and has two hinge points with the straw clamping frame. Driven by the motor, the hinged multi-bar mechanism lifts the straw clamping frame, rotates it 90 degrees, and moves it laterally so that the entire straw clamping frame is located outside the structural frame, thus dispensing the straw bundles.

[0009] The straw unloading machine includes a frame with a fixed frame fixed on it. A slide is slidably mounted on the side of the fixed frame, moving up and down under the drive of a motor. Two wire feeding tubes are fixed on the slide, with a wire inserted into each tube. A first motor is fixed on the slide and rotates a wire rewinder. The front end of the first motor drives a pair of clamping wheels, whose shafts are meshed by gears. The rotation of the clamping wheels pushes the wire downwards. A fixed plate is fixed to the bottom of the frame. The lower end face of the fixed plate is fixedly provided with a lower support sleeve. The lower support sleeve is provided with a contoured annular groove. After the steel wire is moved downward by the clamping wheel, it is formed into a loop along the contoured annular groove. Then, the straw bale is put into the lower support sleeve. The first motor reverses to pull the steel wire upward and tighten the straw bale. Then, the steel wire feeding tube sleeve moves down with the slide frame and is inserted into the soil hole. The frame is also provided with a receiver to support the straw before it is tied by the steel wire and to release the straw after it is tied by the steel wire so that it extends into the soil hole.

[0010] The yam segment discharge mechanism includes a sectional support frame fixed to a chassis frame. A trigger rod is fixedly mounted on the sectional support frame, and a driven gear disk rotates on it. The driven gear disk is driven by a motor via a synchronous belt and then by gear meshing. Several yam segment cylinders are fixedly and annularly on the driven gear disk. The lower ends of the yam segment cylinders pass through the driven gear disk and communicate with the upper surface of the platform. A vertically penetrating discharge cylinder is fixed on the platform, and the lower end of the discharge cylinder extends into a guide cylinder fixedly mounted on the sectional support frame. The yam segment cylinders have branch pipes... The device is equipped with a discharge port, on which a lever is hinged. The tail end of the lever is connected to the discharge port via a spring. The lever slides within the sliding frame and is limited to its maximum position by a limiting body. When the driven gear disk rotates, the yam segment cylinder rotates. Then, the lever is actuated by the trigger rod, causing a segment of yam to be released and fall into the guide cylinder through the discharge cylinder. A linear drive motor is also fixed on the sub-support frame. The push rod at the front end of the linear drive motor pushes the yam that has fallen into the guide cylinder forward so that it falls through the discharge port at the lower end of the guide cylinder.

[0011] The guide rail clamping planter is used to catch the fallen Chinese yam, clamp it, and move it to the planting hole position where the planting hole-punching mechanism will insert the Chinese yam. It includes a first frame plate and a second frame plate. Two symmetrically arranged guide rails are connected between the first frame plate and the second frame plate. Linear sliding bearings are linearly slidingly fitted on the guide rails. A connecting plate is bolted between the two linear sliding bearings. A concentric clamp is provided on the connecting plate. The concentric clamp has a variable diameter clamping hole for clamping the Chinese yam and moving it to the planting hole position for placement.

[0012] In a preferred embodiment, a third drive motor is fixedly mounted on the frame, and synchronous pulleys are rotatably mounted on the upper and lower ends of the frame. A synchronous belt is provided between the synchronous pulleys and the third drive motor, and the third drive motor drives the synchronous belt to move. The slide and the synchronous belt are fixed together by a clamp, so that the third drive motor drives the synchronous belt to move, which in turn drives the slide to move up and down. An upper support sleeve is also fixed on the fixed plate to improve the stability of the straw bales. The receiving device includes a second drive motor and a fully toothed arm and a partially toothed arm rotatably mounted on the frame. The fully toothed arm and the partially toothed arm mesh with gears at the shaft end of the second drive motor. A receiving plate is fixedly mounted at the front end of the fully toothed arm and at the front end of the partially toothed arm. When the two receiving plates are closed, they support the straw.

[0013] In a preferred embodiment, a drive shaft is rotatably mounted on the first frame plate via bearings, and the drive shaft is driven by a motor. A driving synchronous pulley is fixedly mounted on the drive shaft, and a driven synchronous pulley is fixedly mounted and rotatably mounted on the second frame plate. The driving synchronous pulley and the driven synchronous pulley are connected by a discontinuous synchronous belt, and both ends of the discontinuous synchronous belt are fixed to the connecting plate. When the drive shaft is driven by the motor, the movement of the synchronous belt drives the connecting plate and the concentric gripper mounted on the connecting plate to move to a designated position. The concentric gripper includes a right-angle plate hinged below the connecting plate and a driving gear driven by a servo motor rotatably mounted on the right-angle plate. It also includes a plurality of double-headed hinged jaws hinged in a disc-shaped cavity between the right-angle plate and the chuck, which are bolted to the right-angle plate. A torsion spring is provided at the hinge of the double-headed hinged jaws so that the double-headed hinged jaws have a tendency to rotate.

[0014] In a preferred embodiment, a driven drive disk with incomplete teeth is rotatably disposed between the right-angle plate and the clamping plate. Annularly spaced protruding inner pressure blocks are provided within the driven drive disk to abut against the double-headed hinged jaws. The driven drive disk rotates by meshing with the driving gear. The double-headed hinged jaws have two claw ends at the left and right ends of the hinge position, with the outer wall of one end abutted by the inner pressure block and the other end used to clamp the Chinese yam. When the driven drive disk rotates in the direction of the arrow in the figure, the inner pressure block is displaced and thus frees up space. The gap allows the double-headed hinged gripper to rotate under the action of the torsion spring. This causes the end of the double-headed hinged gripper that is not in contact with the driven drive plate to move inward to clamp the Chinese yam. A tension spring is connected between the second frame plate and the first movable frame. When the connecting plate moves to the end away from the first frame plate, the weight causes the front end of the guide rail to move downward, making it easier for the concentric gripper to get closer to the planting hole and for easy placement. The first movable frame is part of the movable frame and its relative position to the drive shaft is fixed.

[0015] In a preferred embodiment, a first tension spring connecting column is fixedly provided on the connecting plate, and a second tension spring connecting column is fixedly provided on the concentric clamp. A limiting spring is connected between the first tension spring connecting column and the second tension spring connecting column, and the rotation stroke of the right-angle plate is ninety degrees, as shown in the figure, which is the limiting position in its planting state. When the connecting plate moves towards the first frame plate, the right-angle plate will contact the second movable frame part and rotate ninety degrees under the obstruction of the second movable frame part, and maintain the filling limiting position under the pull of the limiting spring, so as to facilitate the next filling of Chinese yam planting blocks.

[0016] In a preferred embodiment, a four-bar linkage is also hinged to the structural frame. The bottom bar of the four-bar linkage is connected to a main drive shaft rotatably mounted on the aluminum alloy profile. The main drive shaft rotates under the drive of a motor, causing the four-bar linkage to oscillate cyclically. The two ends of the four-bar linkage are respectively fixed to the left and right driven shafts. Thus, driven by the four-bar linkage, the straw bales are alternately removed from the storage cavity between the straw bins and poured into the straw clamping frame by the left and right U-shaped notch discs.

[0017] Preferably, the straw clamping frame includes a connecting rod that connects and fixes several U-shaped drop frames in series, a second drive motor fixed on the U-shaped drop frames, and a crank clamp driven by the second drive motor. The crank clamp rotates 180 degrees and covers the upper opening of the U-shaped drop frames, thus clamping and fixing the straw bales inside the U-shaped drop frames, ensuring that the straw bales do not shift with the U-shaped drop frames before being moved to the placement position. When the hinged multi-bar mechanism is unfolded to the placement state (Figure), the second drive motor drives the crank clamp to reset, causing the straw bales to fall into the pre-drilled planting pits.

[0018] Preferably, the structural frame is further provided with a hinged multi-bar mechanism for driving the straw clamp and a first drive motor for driving the hinged multi-bar mechanism, the first drive motor being fixed to the aluminum alloy profile. When the hinged multi-bar mechanism is extended to the deployment state, the second drive motor drives the crank clamp to reset, causing the straw bale to fall.

[0019] In a preferred embodiment, the supporting moving mechanism is further provided with a linear drive motor, and the lower end of the planting and drilling mechanism is provided with a sliding member for translation on the chassis frame. The drilling position of the drilling screw coincides with the position where the guide rail clamps the planter to place the Chinese yam. In this way, the device can complete the planting process after moving to a working position without having to move multiple times.

[0020] In a preferred embodiment, a discharge cylinder is bolted to the chassis frame, and a multi-link mechanism driven by a multi-link drive motor is hinged to the base. A bulldozer arm is fixed to the front end of the multi-link mechanism. Two sets of the base, multi-link mechanism, multi-link drive motor, and bulldozer arm are obliquely symmetrically arranged at the bottom of the chassis frame. After the guide rail clamping planter places the Chinese yam, the bulldozer arm pushes the soil near the Chinese yam to cover it.

[0021] The advantages and positive effects of this invention are:

[0022] With a compact and reasonable structure, the original manual planting process is automated. First, the support moving mechanism 22 is moved to the planting position. Then, the planting drilling mechanism 21 drills holes. Next, the straw bundling and filling mechanism 23 inserts straw into the soil holes. Then, the yam segment discharge mechanism 25 discharges a yam segment, which is then clamped by the guide rail clamping planter 16 and moved to the soil hole position and placed down. Finally, the bulldozing arm 35 covers the yam planting block with loose soil near the soil hole. The automation level is high, and it can be operated by a single person.

[0023] It is highly efficient and standardized, greatly improving efficiency compared to manual cultivation. Furthermore, the various indicators of cultivation are more uniform, and the planting pits are more regular, which is conducive to improving the survival rate and development of Chinese yam.

[0024] The steel wire is first unfolded in the contoured groove under the push of the clamping wheel. Then, straw is put in, and the steel wire is tightened under the action of the clamping wheel to tie the lower end of the straw bundle. Then, the steel wire feeding tube is inserted into the soil hole under the action of the slide. Then, the steel wire is released under the push of the clamping wheel and moves downward a distance under the action of the slide to get away from the straw. Then the steel wire is tightened again, and the slide and the steel wire feeding tube are pulled out. The structure is simple and can quickly fix the lower end of the upright straw bundle and insert it into the soil pit. Then it can be withdrawn. It can quickly, accurately and completely insert the straw into the pit. Compared with manual operation, it is more convenient and faster.

[0025] The equipment can pre-load the stored straw bales one by one according to the punching positions for planting Chinese yam, and then insert them upright for burial. Compared with the existing technology that relies on manual operation, it is more convenient and faster. The equipment has a high degree of automation, and the actions are smooth and the equipment is compact.

[0026] The concentric clamps hold the yam planting blocks in place, making them easy to transfer to the pre-drilled planting positions. The concentric clamps holding the yam planting blocks are then moved into place by the translation action of the guide rails and linear sliders before planting. This method is more labor-saving and convenient than traditional manual planting, eliminating the need for repeated bending and kneeling, and freeing people from tiring and repetitive production activities.

[0053] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention. The embodiments of the invention are further described in detail below with reference to the accompanying drawings:

[0054] like Figure 1-23 As shown, the Chinese yam planting machine of the present invention includes the following mechanisms;

[0055] The supporting moving mechanism 22 includes a chassis frame 10 and four moving wheels rotatably mounted on the chassis frame 10. The two moving wheels on the front side are driven by a chassis-only drive motor 11. The chassis-only drive motor 11 and the moving wheels are driven by a sprocket transmission structure 12.

[0056] The planting drilling mechanism 21 includes a drilling frame 13 fixed on the chassis frame 10 and a sliding platform frame 14 slidably mounted on the drilling frame 13. A drilling screw 20 and a drilling drive motor 15 for driving the drilling screw 20 are rotatably mounted on the sliding platform frame 14. The drilling drive motor 15 and the drilling screw 20 are driven by a sprocket transmission structure 12. Fixed pulleys 18 are provided at the bottom and top of the drilling frame 13. A synchronous belt 19 connected between the fixed pulleys 18 is driven by a height drive motor 17. The sliding platform frame 14 is fixedly connected to one side of the synchronous belt 19, thereby allowing the sliding platform frame 14 to move up and down under the drive of the synchronous belt 19.

[0057] The straw bundling and burying mechanism 23 for the Chinese yam planting machine includes a structural frame constructed from aluminum alloy profiles 10c and fastening bolts. Two sets of symmetrical straw bins 14c are fixed to the structural frame via bolts. The space formed between each set of straw bins 14c is used to store bundled straw. A driven shaft 12c is also rotatably mounted on the structural frame via bearings. U-shaped notch discs 13c are fixed at intervals between the driven shafts 12c. The U-shaped notches on the U-shaped notch discs 13c allow individual straw bundles to fall into them when they are facing upwards. Below the structural frame, a straw clamping frame 20c is provided to receive a single bundle of straw that falls from the rotating U-shaped notch disc 13c. A hinged multi-bar mechanism 21c is provided on the structural frame. The hinged multi-bar mechanism 21c is driven by a motor and has two hinge points with the straw clamping frame 20c. Driven by the motor, the hinged multi-bar mechanism 21c lifts the straw clamping frame 20c, rotates it 90 degrees, and moves it laterally so that the entire straw clamping frame 20c is located outside the structural frame, thereby dropping the straw bundle.

[0058] The straw unloading machine 24 includes a frame 10b, on which a fixed frame 14b is fixedly mounted. A slide 13b is slidably mounted on the side of the fixed frame 14b, moving up and down under the drive of a motor. Two wire feeding tube sleeves 15b are fixedly mounted on the slide 13b, and a wire 27b is inserted into the wire feeding tube sleeves 15b. A first motor 12b is fixedly mounted on the slide 13b, and a wire winding device 11b is rotatably mounted thereon. The front end of the first motor 12b drives a pair of clamping wheels, whose shafts are meshed by gears. When the clamping wheels rotate, they push the wire 27b downwards. A fixing plate is fixedly mounted at the bottom of the frame 10b. 16b, a lower support sleeve 23b is fixedly provided on the lower end face of the fixed plate 16b. The lower support sleeve 23b is provided with a contoured annular groove 24b. After the steel wire 27b is moved downward by the clamping wheel, it is formed into a loop along the contoured annular groove 24b. Then, the straw bale is put into the lower support sleeve 23b. The first motor 12b reverses to pull the steel wire 27b upward, thereby tightening the straw bale. Then, the steel wire feeding tube sleeve 15b moves down with the slide frame 13b and is inserted into the soil hole. The frame 10b is also provided with a receiver 19b to support the straw before it is tied by the steel wire 27b and to release the straw after it is tied by the steel wire 27b so that it extends into the soil hole.

[0059] The yam segment discharge mechanism 25 includes a sectional support frame 45 fixed on the chassis frame 10. A trigger rod 44 is fixedly mounted on the sectional support frame 45, and a driven gear disk 42 is rotatably mounted thereon. The driven gear disk 42 is driven by a motor through synchronous belt transmission and gear meshing. Several yam segment cylinders 41 are fixedly fixedly arranged in a ring at intervals on the driven gear disk 42. The lower end of each yam segment cylinder 41 passes through the driven gear disk 42 and communicates with the upper end face of the platform 43. A discharge cylinder 39 that runs vertically through the platform 43 is fixedly mounted on the platform 43, and the lower end of the discharge cylinder 39 extends into the guide cylinder 31 fixedly mounted on the sectional support frame 45. The yam segment cylinders 41 have branch pipes with... A discharge port 26 is provided, and a lever 29 is hinged to the discharge port 26. The tail end of the lever 29 is connected to the discharge port 26 by a spring 30. The lever 29 slides in the sliding frame 27 and is limited to the maximum position by the limiting body 28. When the driven gear disk 42 rotates, the yam segment material cylinder 41 rotates. Then the lever 29 is pushed by the trigger rod 44, which releases a segment of yam and drops it into the guide cylinder 31 through the discharge cylinder 39. A linear drive motor 34 is also fixed on the sub-support frame 45. The push rod at the front end of the linear drive motor 34 pushes the yam that has fallen into the guide cylinder 31 forward so that it falls into the discharge port 33 at the lower end of the guide cylinder 31.

[0060] The guide rail clamping planter 16 is used to catch the Chinese yam that falls from the 33 and clamp it before moving it to the planting hole position where the planting hole-punching mechanism 21 punches a hole to put the Chinese yam in. It includes a first frame plate 20a and a second frame plate 12a. Two symmetrically arranged guide rails 29a are connected between the first frame plate 20a and the second frame plate 12a. Linear sliding bearings 16a are linearly slidingly fitted on the guide rails 29a. A connecting plate 28a is bolted between the two linear sliding bearings 16a. A concentric clamping device 14a is provided on the connecting plate 28a. The concentric clamping device 14a has a variable diameter clamping hole for clamping the Chinese yam and moving it to the planting hole position for putting it in.

[0061] In a preferred embodiment, a third drive motor 25b is fixedly mounted on the frame 10b. Synchronous pulleys are rotatably mounted at the upper and lower ends of the fixed frame 14b, and a synchronous belt 26b is provided between the synchronous pulleys and the third drive motor 25b. The third drive motor 25b drives the synchronous belt 26b to move. The slide 13b and the synchronous belt 26b are fixed together by a clamp. Thus, after the third drive motor 25b drives the synchronous belt 26b to move, it will cause the slide 13b to move up and down. The fixed plate 16b also has... An upper support sleeve 17b is fixedly provided to improve the stability of the straw bale placement. The receiving device 19b includes a second drive motor 20b and a full-toothed arm 21b and a partial-toothed arm 22b rotatably mounted on the frame 10b. The full-toothed arm 21b and the partial-toothed arm 22b are engaged with the gears at the shaft end of the second drive motor 20b. A receiving plate 18b is fixedly provided at the front end of the full-toothed arm 21b and the front end of the partial-toothed arm 22b. When the two receiving plates 18b are closed, they support the straw.

[0062] In a preferred embodiment, a drive shaft 21a is rotatably mounted on the first frame plate 20a via bearings, and the drive shaft 21a is driven by a motor. A driving synchronous pulley 22a is fixedly mounted on the drive shaft 21a, and a driven synchronous pulley 13a is fixedly mounted on the second frame plate 12a. The driving synchronous pulley 22a and the driven synchronous pulley 13a are connected by a discontinuous synchronous belt, and both ends of the discontinuous synchronous belt are fixed to the connecting plate 28a. When the drive shaft 21a is driven by the motor, the movement of the synchronous belt drives the connecting plate 28a and the driven synchronous pulley 13a. The concentric clamp 14a on the connecting plate 28a moves to a designated position. The concentric clamp 14a includes a right-angle plate 27a hinged below the connecting plate 28a and a drive gear 23a driven by a servo motor rotatably mounted on the right-angle plate 27a. It also includes a chuck 30a bolted to the right-angle plate 27a. Several double-headed hinged jaws 26a are hinged in the disc-shaped cavity between the right-angle plate 27a and the chuck 30a. A torsion spring is provided at the hinge of the double-headed hinged jaws 26a so that the double-headed hinged jaws 26a have a tendency to rotate.

[0063] In a preferred embodiment, a driven drive disk 24a with incomplete teeth is rotatably provided between the right-angle plate 27a and the clamping disk 30a. Annularly spaced protruding inner pressure blocks 25a are provided within the driven drive disk 24a to abut against the double-headed hinged jaws 26a. The driven drive disk 24a rotates by meshing with the driving gear 23a. The double-headed hinged jaws 26a have two jaw ends at the left and right ends of the hinged position, with the outer wall of one end abutted by the inner pressure block 25a and the other end used to clamp the Chinese yam. When the driven drive disk 24a moves along... Figure 2 After rotating in the direction of the arrow, the inner pressure block 25a is displaced, creating a gap that allows the double-headed hinged gripper 26a to rotate under the action of the torsion spring. This causes the end of the double-headed hinged gripper 26a that is not in contact with the driven drive disk 24a to move inward and clamp the Chinese yam. A tension spring 11a is connected between the second frame plate 12a and the moving frame part 10a. When the connecting plate 28a moves to a position away from the first frame plate 20a, the front end of the guide rail 29a moves downward under the action of weight, making it easier for the concentric gripper 14a to get closer to the planting hole and facilitate placement. The moving frame part 10a is part of the moving frame and its relative position to the drive shaft 21a is fixed.

[0064] In a preferred embodiment, a first tension spring connecting post 18a is fixedly provided on the connecting plate 28a, and a second tension spring connecting post 19a is fixedly provided on the concentric clamp 14a. A limiting spring is connected between the first tension spring connecting post 18a and the second tension spring connecting post 19a, and the rotational stroke of the right-angle plate 27a is ninety degrees. Figure 1 The diagram shows the limit position in its planting state. When the connecting plate 28a moves toward the first frame plate 20a, the right-angle plate 27a will contact the second movable frame part 15a and rotate 90 degrees under the obstruction of the second movable frame part 15a. Under the pull of the limit spring, it will maintain the filling limit position, which will facilitate the next filling of Chinese yam planting blocks.

[0065] In a preferred embodiment, a four-bar linkage 11c is also hinged to the structural frame. The bottom bar of the four-bar linkage 11c is connected to a main drive shaft 23c rotatably mounted on the aluminum alloy profile 10c. The main drive shaft 23c rotates under the drive of a motor, causing the four-bar linkage 11c to swing cyclically. The two ends of the four-bar linkage 11c are respectively fixed to the left and right driven shafts 12c. Thus, driven by the four-bar linkage 11c, the straw bales are alternately removed from the storage cavity between the straw bin plates 14c and poured into the straw clamping frame 20c by the left and right U-shaped notch discs 13c.

[0066] Preferably, the straw clamping frame 20c includes a connecting rod 19c that connects and fixes several U-shaped drop frames 18c in series, and also includes a second drive motor 16c fixed on the U-shaped drop frames 18c and a crank clamp 17c driven by the second drive motor 16c. The crank clamp 17c rotates 180 degrees and covers the upper opening of the U-shaped drop frames 18c, thereby clamping and fixing the straw bales inside the U-shaped drop frames 18c, ensuring that the straw bales do not shift with the U-shaped drop frames 18c before being moved to the placement position. When the hinged multi-bar mechanism 21c is unfolded to the placement state (… Figure 25 Then the second drive motor 16c drives the crank clamp 17c to reset, so that the straw bale falls into the pre-drilled planting pit.

[0067] Preferably, the structural frame is further provided with a hinged multi-bar mechanism 21c for driving the straw clamp 20c and a first drive motor 22c for driving the hinged multi-bar mechanism 21c. The first drive motor 22c is fixed to the aluminum alloy profile 10c. When the hinged multi-bar mechanism 21c is unfolded to the deployment state, the second drive motor 16c drives the crank clamp 17c to reset, causing the straw bale to fall.

[0068] In a preferred embodiment, the supporting moving mechanism 22 is also provided with a linear drive motor, and the lower end of the planting and drilling mechanism 21 is provided with a sliding member for translation on the chassis frame 10. The drilling position of the drilling screw 20 coincides with the position where the guide rail clamping planter 16 puts in the Chinese yam. In this way, the device can complete the planting process after moving to a working position without having to move multiple times.

[0069] In a preferred embodiment, a discharge cylinder 39 is bolted to the chassis frame 10, and a multi-link mechanism 36 driven by a multi-link drive motor 37 is hinged to the base 38.

After the guide rail clamping planter 16 places the Chinese yam, the bulldozing arm 35 pushes the soil near the Chinese yam to cover it.

[0070] In practice, the supporting moving mechanism 22 is first moved to the planting position, and then the planting drilling mechanism 21 drills holes. Then, the straw bundling and burying mechanism 23 of the Chinese yam planter inserts straw into the soil hole. Then, the Chinese yam segment discharge mechanism 25 discharges a Chinese yam segment, which is then clamped by the guide rail clamping planter 16 and moved to the soil hole position and placed down. Finally, the bulldozing arm 35 covers the loose soil near the soil hole onto the Chinese yam planting block.

The lever slides within the sliding frame and is limited to its maximum position by a limiting body. When the driven gear disk rotates, the yam segment cylinder rotates. Then, the lever is actuated by the trigger rod, causing a segment of yam to be released and fall into the guide cylinder through the discharge cylinder. A linear drive motor is also fixed on the sub-support frame. The push rod at the front end of the linear drive motor pushes the yam that has fallen into the guide cylinder forward so that it falls through the discharge port at the lower end of the guide cylinder.
