Description

Technical Field

[0001] This application pertains to the field of yam cultivation, specifically relating to a fully automatic yam cultivation machine. Background Technology

[0002] With technological advancements and development, the use of machinery in agriculture has increased significantly. The use of agricultural machinery can greatly improve agricultural efficiency, and mechanization is indispensable in modern large-scale agricultural production. Agricultural mechanization has significantly improved agricultural production efficiency and quality, while also providing farmers with better working conditions, which is of great significance to the development of modern agriculture.

[0003] Among many crops, yam is highly favored in the Chinese market, especially in recent years. With people's pursuit of healthy lifestyles and increased awareness of food safety, yam, with its natural and healthy characteristics, has become increasingly popular with consumers. Whether used as a main ingredient in cooking or as a nutritional supplement, yam can meet people's needs for a balanced diet, which is a major reason for the continuous expansion of the yam market.

[0004] Yam cultivation uses 10-15cm long young yam segments, making it impossible to use commercially available seed planters. Furthermore, as yams are vine-like plants, they require support and management to ensure upward growth and sufficient light and ventilation, placing high demands on climbing trellises. Subsequent tasks such as inserting stakes must be done manually, using bamboo poles or branches for tying, resulting in low efficiency. Traditional yam cultivation is entirely manual, a highly seasonal and labor-intensive job. Prolonged bending over during cultivation is extremely harmful to farmers' health, and planting efficiency is low. Therefore, some have begun to develop automated yam planting machines, such as the yam planting machine disclosed in Chinese patent CN112535004B. However, this patent only achieves semi-automated planting, reducing labor intensity and improving planting efficiency to some extent, but still requiring manual labor. Moreover, it cannot automatically construct climbing trellises, leaving the overall planting efficiency needing improvement.

[0005] Therefore, it is of great significance to invent a fully automatic yam planting machine that can realize the mechanization and automation of yam planting. Summary of the Invention

The first motor is connected to at least one tire via a coupling for transmitting torque to the tire.

[0017] As a preferred embodiment of this application, the fully automatic yam planter adopts a six-wheel rear-wheel drive mode. The two rear-mounted first motors are connected to the tires on both sides of the rear of the chassis module through a coupling, thereby transmitting torque to the tires on both sides. The torque transmission is achieved by the wheel transmission assembly.

[0018] As a preferred embodiment of this application, the watering module includes a water tank, an outlet pipe and a limiting hole disposed on the water tank, a water pump is provided inside the water tank, the outlet of the water pump is connected to a water pipe, and the outlet end of the water pipe is guided to the designated watering position by passing through the outlet pipe and the limiting hole in sequence.

[0019] As a preferred embodiment of this application, the grooving and loosening module includes a second motor, a chain-type loosening mechanism, and a grooving mechanism. The chain-type loosening mechanism is connected to the second motor and is used to loosen the soil in the planting area and break up any fertilizer that falls into the planting area and mix it into the soil. The grooving mechanism is located behind the chain-type loosening mechanism and includes a grooving component and a lifting and adjusting component. The grooving component is located at the bottom of the lifting and adjusting component and is used to groove the loosened soil.

The bottom of the rack is connected to a grooving component, which is used to drive the grooving component to move up and down to create planting grooves in the loosened soil.

[0021] As a preferred embodiment of this application, the fertilization module includes a fourth motor, a feeding component, a fertilizer storage bin, and a partition. The fertilizer storage bin has a discharge port on its side, and the bottom of the fertilizer storage bin has a feeding component and a partition. The partition is located below the feeding component, and the front end of the partition extends to near the discharge port. The fourth motor is connected to the feeding component through a first transmission assembly and is used to push the fertilizer in the fertilizer storage bin from the front end of the partition through the discharge port onto the planting area.

[0022] As a preferred embodiment of this application, the yam separation and covering module includes a fifth motor, a yam storage bin, a yam separating component, a conveyor belt, a yam slide rail, and a covering component. The yam separating component is rotatably installed inside the yam storage bin, and a conveyor belt is laid below the yam separating component. The fifth motor is connected to the yam separating component and the conveyor belt through a second transmission component, and is used to drive the yam separating component to rotate so that the yam stalks in the yam storage bin fall onto the conveyor belt. The yam slide rail is inclined, with the upper feed end of the yam slide rail located below the output end of the conveyor belt, and the lower discharge end extending to the rear of the grooving component, for sending the yam stalks output by the conveyor belt into the planting trough. The covering component is located behind the grooving and loosening module, for covering the soil removed by the grooving and loosening module back into the planting trough.

[0023] As a preferred embodiment of this application, the yam separating component is a cylindrical component, and the outer wall of the cylindrical component is provided with a separating groove extending along its own axis for separating yam stems.

[0024] As a preferred embodiment of this application, the angle between the yam slide rail and the horizontal direction is 20°.

[0025] As a preferred embodiment of this application, the insertion module includes a storage compartment, a climbing frame pole separator, a climbing frame pole guide rail, a pressure rod component, a climbing frame pole support component, and a climbing frame pole arc rail. The storage compartment has a pole outlet hole at its bottom for individual climbing frame poles to enter and exit. The climbing frame pole separator is located below the storage compartment and connected to a sixth motor for individually removing climbing frame poles from the storage compartment. The climbing frame pole guide rail is located below the climbing frame pole separator for guiding the individual climbing frame poles separated by the separator to the climbing frame. In the trellis support component; the climbing trellis support component is located below the climbing trellis guide rail, and the climbing trellis support component has an upward-facing positioning groove for receiving the climbing trellis pole sent from the climbing trellis guide rail; the pressure bar component is located above the climbing trellis support component and is connected to the lifting drive mechanism, for pressing the two ends of the climbing trellis pole on the climbing trellis support component into the soil; the climbing trellis arc rail is rotatably installed below the climbing trellis support component and is connected to the rotation drive mechanism, for cooperating with the pressure bar component to shape the climbing trellis pole.

[0026] As a preferred embodiment of this application, the rod storage compartment is a V-shaped compartment with a rod outlet hole at the bottom.

[0027] As a preferred embodiment of this application, the climbing frame pole separator is rotatably mounted below the pole outlet hole and connected to a sixth motor. The outer wall of the climbing frame pole separator is provided with an axial groove for accommodating a single climbing frame pole, and the gap between the axial groove and the pole outlet hole is smaller than the outer diameter of the climbing frame pole, which can ensure that only one climbing frame pole is separated at a time. When the axial groove of the climbing frame pole separator rotates to be directly below the pole outlet hole, the climbing frame pole falls into the axial groove of the climbing frame pole separator to achieve the removal of a single climbing frame pole. As the climbing frame pole separator rotates, it is guided by the climbing frame pole guide rail to fall into the positioning groove of the climbing frame pole support component.

[0028] As a preferred embodiment of this application, the pressure bar component is an inverted U-shaped or U-shaped pressure bar component. The pressure bar component is vertically raised and lowered on the vertical plane under the drive of the lifting drive mechanism, and is used to press the two ends of the climbing frame pole, which is placed horizontally in the positioning groove of the climbing frame pole support component, downward into the soil.

[0029] As a preferred embodiment of this application, the lifting drive mechanism includes a lifting motor, a lead screw, and a lifting seat. The lifting motor is connected to the vertically arranged lead screw, and the lifting seat is sleeved on the lead screw and threadedly connected to the lead screw. The lifting motor drives the lead screw to rotate, causing the lifting seat to drive the pressure rod component to rise or fall.

[0030] As a preferred embodiment of this application, the climbing frame pole is made of a material with good toughness and plasticity. During the downward movement of the pressure rod component, the arc track of the climbing frame pole is always supported in the middle of the climbing frame pole. Since the climbing frame pole is made of a material with good toughness and plasticity, it bends and deforms when its two ends are pressed downward, so that the two ends of the climbing frame pole can be inserted into the soil. Through the repeated pressing back and forth of the pressure rod component, the bent and deformed climbing frame pole can be firmly inserted into the soil.

[0031] As a preferred embodiment of this application, the cross-section of the arc-shaped rail of the climbing trellis pole is fan-shaped, and an arc-shaped molding groove for accommodating the climbing trellis pole is provided on the arc surface of the arc-shaped rail. After both ends of the climbing trellis pole are firmly inserted into the soil, it is lifted, and the arc-shaped rail, which was previously supported in the middle of the climbing trellis pole, rotates 180° counterclockwise, causing the climbing trellis pole to detach from the machine, thus realizing the function of building a climbing frame and facilitating yam growth. The pressure rod component and the arc-shaped rail of the climbing trellis pole together shape the climbing trellis pole, forming an upward-convex arc segment in the middle of the climbing trellis pole. After both ends of the climbing trellis pole are firmly inserted into the soil, it is lifted, and the arc-shaped rail, which was previously supported in the middle of the climbing trellis pole, rotates 180° counterclockwise, causing the climbing trellis pole to detach from the machine, thus realizing the function of building a climbing frame and facilitating yam growth. The pressure rod component and the arc rail of the climbing frame pole work together to shape the climbing frame pole, so that the middle of the climbing frame pole forms an upward convex arc segment.

[0032] As a preferred embodiment of this application, a cushioning material is placed at the front end of the yam slide rail to reduce the impact on the yam.

[0033] As a preferred embodiment of this application, the yam slide rail is wider at the front and narrower at the back, thus limiting the movement of the yam.

[0034] As a preferred option in this application, the climbing frame poles are made of materials with good toughness and plasticity, such as plastic or iron wire.

[0035] As a preferred embodiment of this application, the pressure bar component is repeatedly pressed down, making the climbing frame pole more firmly inserted into the soil.

[0036] Compared with the prior art, the present invention has the following advantages:

[0037] 1. This invention automates the entire process of yam cultivation, from trenching and loosening the soil to fertilizing and watering, separating and sowing yams, covering with soil, and inserting stakes, all without the need for manual labor, greatly improving cultivation efficiency.

[0039] 3. This invention minimizes material loss and ensures the integrity of yam seed segments and a high planting success rate through multiple deceleration and anti-drop designs.

[0040] 4. The present invention has a compact structure, high space utilization, and good safety and stability. Attached Figure Description

[0066] like Figure 1 and Figure 2 As shown, the fully automatic yam planting machine of the present invention includes:

[0067] Chassis module 1 is used to support and drive the entire machine to move;

[0068] Watering module 2, located at the front left of chassis module 1, is used to water the planting area to ensure the soil is moist;

[0069] The trenching and loosening module 3 is located at the front right of the chassis module 1 and is used for loosening and trenching the soil in the planting area.

[0070] Fertilization module 4, located above trenching and loosening module 3, is used to automatically apply fertilizer to the planting area.

[0071] The yam separation and soil covering module 5 is located behind the trenching and loosening module 3 and is used to realize the automatic sowing and soil covering of yams;

[0072] The pole module 6, located behind the yam separation and soil covering module 5, is used to construct the climbing frame required for yam growth; and / or

[0073] The control module is installed on the chassis module 1 and connected to the chassis module 1, watering module 2, trenching and loosening module 3, fertilization module 4, yam separation and covering module 5 and pole module 6. It is used to control the status and operation of the chassis module 1, watering module 2, trenching and loosening module 3, fertilization module 4, yam separation and covering module 5 and / or pole module 6.

[0074] like Figure 3 As shown, the chassis module 1 includes a frame 35, several pairs of tires 31 rotatably mounted on the frame 35, and a first motor 32 mounted on the frame 35 for driving. The first motor 32 is connected to at least one tire 31 via a coupling 33 for transmitting torque to the tire 31.

[0075] like Figure 3 As shown, the fully automatic yam planter adopts a six-wheel rear-drive mode with six tires symmetrically arranged (two in the front and four in the rear). The two rear-mounted first motors 32 are connected to the tires 31 on both sides of the rear of the chassis module via couplings 33, thereby transmitting torque to the tires 31 on both sides. Torque transmission is achieved through a wheel-type transmission assembly 34. Specifically, the two rear-mounted first motors 32 transmit torque to the tires 31 on both sides via couplings 33 and fixing components. Five gears are arranged at equal intervals to form the wheel-type transmission assembly 34, achieving torque transmission. Two frames 35 are placed symmetrically to support the entire machine and connect the various modules, ensuring the stability and reliability of the entire machine during operation.

[0076] like Figure 3 As shown, the chassis module 1 is symmetrically arranged. The first motor 32 realizes the forward and steering functions of the whole machine. The coupling 33 is used to transmit the motor torque. The frame 35 is used to support the whole machine and connect the modules to ensure the stability and reliability of the whole machine in the working process.

[0077] like Figure 4 As shown, the watering module 2 includes a water tank 40, an outlet 41 and a limiting hole 42 set on the water tank. A water pump is installed in the water tank 40. The outlet of the water pump is connected to a water pipe. The water outlet of the water pipe passes through the outlet 41 and the limiting hole 42 in sequence and is guided to the designated watering position. The water is transported to the nozzle and sprays a uniform fine water column near the trench and loosened soil to keep the soil moist.

[0078] like Figure 4 As shown, in the watering module 2, the outlet 41 and the limiting hole 42 are designed according to the water pipe diameter and the watering position.

[0079] like Figure 5 , Figure 6 as well as Figure 7As shown, the grooving and loosening module 3 includes a second motor 51, a chain-type loosening mechanism, and a grooving mechanism. The chain-type loosening mechanism is connected to the second motor 51 and is used to loosen the soil in the planting area and break up any fertilizer that falls into the planting area and mix it into the soil. The grooving mechanism is located behind the chain-type loosening mechanism and includes a grooving component 68 and a lifting and adjusting component. The grooving component 68 is located at the bottom of the lifting and adjusting component and is used to groove the loosened soil. The lifting and adjusting component is connected to the chain-type loosening mechanism and is used to adjust the height of the grooving component 68 under the drive of the chain-type loosening mechanism.

[0080] like Figure 5 , Figure 6 as well as Figure 7 As shown, the chain-type soil loosening mechanism includes a worm gear 61 rotatably mounted on a frame 35, a worm wheel 62 meshing with the worm gear 61, a bracket 63 connected to the worm wheel 62, sprockets 55 rotatably mounted at both ends of the bracket, a third motor 53 for driving the sprockets 55 to rotate, and a second chain 54 surrounding and tensioned around the two sprockets 55. The second motor 51 is connected to the end of the worm gear 61 via the first chain 52; the third motor 53 is connected to one of the sprockets 55 and is used to drive the second sprocket 61 to rotate. The chain 54 moves circumferentially around the bracket 63; the lifting and adjusting component includes a transmission wheel 64 rotatably mounted on the frame 35, a slide bar 66 set on the frame 35, a slider 65 set on the slide bar 66, and a rack 67 connected to the slider 65. The transmission wheel 64 is located between the worm gear 62 and the rack 67 and meshes with the worm gear 62 and the rack 67. The bottom of the rack 67 is connected to a grooving component 68, which is used to drive the grooving component 68 to move up and down to open planting grooves in the loosened soil. During soil loosening, the second motor 51 drives the worm 61 and worm wheel 62 to rotate via the first chain 52, causing the support 63 to rotate counterclockwise. Since one end of the support 63 is mounted on the worm wheel 62, the other end of the support 63 can descend periodically. At this time, the third motor 53 starts, driving the second chain 54 to rotate around the support 63. Soil loosening is achieved during the rotation of the second chain 54. When the worm wheel 62 rotates counterclockwise, the transmission wheel 64 causes the rack 67 to move vertically up and down on the slider 65 and the slide rod 66, while simultaneously driving the grooving component 68 up and down, thereby performing grooving.

[0081] like Figure 6 As shown, the slotted component 68 adopts a conical structure and has a serrated structure at the bottom to realize the slotting function. The slotting is realized when the chassis module 1 is started.

[0082] like Figure 8 and Figure 9As shown, the fertilization module 4 includes a fourth motor 81, a feeding component 84, a fertilizer storage bin 85, and a partition 92. The fertilizer storage bin 85 has a discharge port on its side. The inner bottom of the fertilizer storage bin 85 is provided with the feeding component 84 and the partition 92. The partition 92 is located below the feeding component 84, and the front end of the partition 92 extends to near the discharge port. The fourth motor 81 is connected to the feeding component 84 through a first transmission assembly and is used to push the fertilizer 91 in the fertilizer storage bin 85 out of the front end of the partition 92 through the discharge port and onto the planting area.

[0083] like Figure 8 and Figure 9 As shown, the first transmission component includes a first gear 82 and a third chain 83. The first gear 82 is connected to the fourth motor 81. The feeding component 84 includes a feeding shaft 841 and a feeding transmission gear 842 disposed at one end of the feeding shaft. The feeding shaft 841 is rotatably disposed at the inner bottom of the fertilizer storage bin 85. A spiral feeding groove 8411 is provided on the feeding shaft 841, which is used to push the fertilizer 91 in the fertilizer storage bin 85 from the front end of the partition 92 through the discharge port and fall into the planting area during the rotation of the feeding shaft. The third chain 83 is wrapped around the outside of the first gear 82 and the feeding transmission gear 842 and is tensioned, which is used to realize the power transmission between the first gear 82 and the feeding transmission gear 842.

[0084] like Figure 8 and Figure 9 As shown, in the fertilization module 4, the feeding component 84 flexibly adjusts the screw pitch and number of turns according to different sizes of fertilizer 91. The fertilizer storage bin 85 has a V-shaped structure. When the fourth motor 81 starts, it drives the third chain 83 through the first gear 82 to rotate the feeding component 84, slowly pushing the fertilizer 91 in the V-shaped fertilizer storage bin 85 out from the front end of the partition 92. The fertilizer is then broken up and mixed into the soil by the second chain 54 in the lower grooving and loosening module 3, achieving the effect of applying base fertilizer. The screw pitch of the feeding component 84 varies according to the size of the fertilizer 91.

[0085] like Figure 10 , Figure 11 , Figure 12 as well as Figure 13As shown, the yam separation and covering module 5 includes a fifth motor 101, a yam storage bin 105, a yam separating component 112, a conveyor belt 113, a yam slide rail 114, and a covering component 115. The yam separating component 112 is rotatably installed inside the yam storage bin 105. The conveyor belt 113 is laid below the yam separating component 112. The fifth motor 101 is connected to the yam separating component 112 and the conveyor belt 113 through a second transmission assembly to drive the yam separating component. 112 rotates to drop the yam stalks 111 in the yam storage bin 105 onto the conveyor belt 113; the yam slide rail 114 is inclined, with the upper feed end of the yam slide rail 114 located below the output end of the conveyor belt 113, and the lower discharge end extending to the rear of the grooving component 68, for sending the yam stalks 111 output by the conveyor belt 113 into the planting trough; the soil covering component 115 is located behind the grooving and loosening module 3, for covering the soil cut out by the grooving and loosening module 3 back into the planting trough.

[0086] like Figure 10 As shown, the second transmission assembly includes a fourth chain 102, a transmission shaft 103, and a second gear 104. The output shaft of the fifth motor 101 is equipped with a power output gear. The fourth chain 102 surrounds the power output gear and the transmission shaft 103 and is tensioned. The transmission shaft 103 is connected to the conveyor belt 113 and is connected to the yam separator 112 through the second gear 104. The fifth motor 101 transmits torque to the transmission shaft 103 through the fourth chain 102, causing the second gear 104 to rotate, which in turn drives the yam separator 112 to rotate. The yam stalks 111 in the yam storage bin 105 are separated by the yam separator 112 and fall onto the lower conveyor belt 113. The conveyor belt 113 is driven by the transmission shaft 103 to drop the yam stalks 111 into the yam slide rail 114. The soil covering component 115 covers the soil cut out by the trenching and loosening module 3 back into the trench.

[0087] like Figure 10 As shown, the yam separating component 112 includes a connecting shaft 1123 rotatably disposed in the yam storage chamber 105, a separating cylindrical component 1124 disposed on the connecting shaft, and a separating transmission gear 1125. The outer wall of the separating cylindrical component 1124 is provided with a separating through groove 1121 extending along its own axis for separating the yam stem 111. The separating transmission gear 1125 is coaxially assembled with the second gear 104, thereby enabling the second gear 104 and the separating transmission gear 1125 to rotate synchronously.

[0088] like Figure 11 As shown, there are multiple sets of yam separators 112, which are installed side by side on the yam storage bin 105. The yam separators 112 are connected by a transmission chain 1122 that surrounds the separator transmission gear, thereby realizing the power transmission between the multiple sets of yam separators 112.

[0089] like Figure 11 As shown, the angle between the yam slide rail 114 and the horizontal direction is 20°.

[0090] like Figure 6 As shown, in the grooving and loosening module 3, worm gears 61, worm wheels 62 and transmission wheels 64 of different sizes are designed according to different transmission speed ratios. The second chain 54 is driven by the third motor 53 to rotate at high speed, breaking up the soil to achieve the function of loosening the soil.

[0091] like Figure 6 As shown, in the yam separation and covering module 5, the yam storage bin 105 is equipped with multiple yam separating components 112 arranged at equal intervals, so that multiple yam stalks 111 fall into the conveyor belt 113 at equal intervals. At the same time, the yam slide rail 114 is at a 20° angle to the ground, and the covering component 115 is at a 120° angle. The fifth motor 101 transmits torque to the drive shaft 103 through the fourth chain 102, so that the second gear 104 rotates, so that the yam stalks 111 in the yam storage bin 105 are separated at equal intervals by the yam separating components 112 and fall onto the conveyor belt 113. The conveyor belt 113 is driven by the drive shaft 103, so that the yam stalks 111 fall into the yam slide rail 114 at a 20° angle to the ground, and further fall into the opened trough. The covering component 115 is at a 120° angle, so that the soil opened by the troughing and loosening module 3 can be covered back into the trough.

[0092] like Figure 14 and Figure 15 As shown, the insertion rod module 6 includes a rod storage compartment 140, a climbing frame rod separator 141, a climbing frame rod guide rail 142, a pressure rod component 143, a climbing frame rod support component 144, and a climbing frame rod arc rail 146. The bottom of the rod storage compartment 140 is provided with a rod outlet hole for single climbing frame rods 145 to enter and exit. The climbing frame rod separator 141 is located below the rod storage compartment 140 and connected to a sixth motor 147 for individually removing climbing frame rods 145 from the rod storage compartment 140. The climbing frame rod guide rail 142 is located below the climbing frame rod separator 141 for guiding the single climbing frame rods 145 separated by the climbing frame rod separator 141 to the climbing frame. In the trellis support component 144; the trellis support component 144 is located below the trellis guide rail 142, and the trellis support component 144 has an upward-facing positioning groove for receiving the trellis pole 145 sent from the trellis guide rail 142; the pressure rod component 143 is located above the trellis support component 144 and is connected to a lifting drive mechanism for pressing the two ends of the trellis pole 145 on the trellis support component 144 into the soil; the trellis arc rail 146 is rotatably installed below the trellis support component 144 and is connected to a seventh motor 151 for cooperating with the pressure rod component 143 to shape the trellis pole 145.

[0093] like Figure 15As shown, the rod storage compartment 140 is a V-shaped compartment with a rod outlet hole at the bottom.

[0094] like Figure 15 As shown, the climbing frame pole separating component 141 is rotatably installed below the pole outlet hole and connected to the sixth motor 147. The outer wall of the climbing frame pole separating component 141 is provided with an axial groove 1411 for accommodating a single climbing frame pole 145, and the gap between the axial groove and the pole outlet hole is smaller than the outer diameter of the climbing frame pole 145, which can ensure that only one climbing frame pole 145 is separated at a time. When the axial groove of the climbing frame pole separating component 141 rotates to directly below the pole outlet hole, the climbing frame pole 145 falls into the axial groove of the climbing frame pole separating component 141 to realize the removal of a single climbing frame pole 145. As the climbing frame pole separating component 141 rotates, it is guided by the climbing frame pole guide rail 142 into the positioning groove 1441 of the climbing frame pole support component 144.

[0095] like Figure 15 As shown, the bottom of the positioning groove 1441 has a slope 1442 that is lower in the front and higher in the back. After being guided by the climbing frame rod guide rail 142, the climbing frame rod 145 falls into the positioning groove 1441 in a horizontal posture. Guided by the slope 1442, the climbing frame rod 145 is sent into the fixed position of the positioning groove 1441, so that the pressure rod component 143 can smoothly press down on the end of the climbing frame rod 145.

[0096] like Figure 14 As shown, the pressure bar component 143 is an inverted U-shaped, V-shaped, U-shaped or V-shaped pressure bar. The pressure bar component 143 is vertically raised and lowered on the vertical plane under the drive of the lifting drive mechanism, and is used to press the two ends of the climbing frame pole 145, which is horizontally placed in the positioning groove of the climbing frame pole support component 144, downward into the soil.

[0097] like Figure 14 As shown, the lifting drive mechanism includes a lifting motor 148, a lead screw 149, and a lifting seat 150. The lifting motor 148 is connected to the vertically arranged lead screw 149, and the lifting seat 150 is sleeved on the lead screw 149 and threadedly connected to the lead screw 149. The lifting motor 148 drives the lead screw 149 to rotate, so that the lifting seat 150 drives the pressure rod component 143 to rise or fall.

[0098] like Figure 14 As shown, the climbing frame pole 145 is made of a material with good toughness and plasticity. During the downward movement of the pressure rod component 143, the arc rail 146 of the climbing frame pole is always supported in the middle of the climbing frame pole 145. Since the climbing frame pole 145 is made of a material with good toughness and plasticity, it undergoes downward bending deformation when its two ends are pressed down. The two ends of the climbing frame pole 145 can be inserted into the soil. By repeatedly pressing down back and forth by the pressure rod component 143, the bent and deformed climbing frame pole 145 can be firmly inserted into the soil.

[0099] like Figures 14-16 As shown, the cross-section of the arc-shaped rail 146 of the climbing trellis is fan-shaped, and an arc-shaped molding groove 1461 for accommodating the climbing trellis pole 145 is provided on the arc surface of the arc-shaped rail 146. After the two ends of the climbing trellis pole 145 are firmly inserted into the soil, it is lifted, and the arc-shaped rail 146, which was previously supported in the middle of the climbing trellis pole 145, rotates 180° counterclockwise, so that the climbing trellis pole 145 is detached from the whole machine, realizing the function of building a climbing frame, which is conducive to the growth of yam. The pressure rod component 143 and the arc-shaped rail 146 of the climbing trellis together shape the climbing trellis pole 145, so that the middle part of the climbing trellis pole 145 forms an upward convex arc segment, while the two ends of the climbing trellis pole 145 are inserted into the soil.

[0100] like Figure 16 As shown, the pressure rod component 143 is an inverted U-shaped structure that can press the two ends of the climbing frame rod 145 and work together with the climbing frame rod arc rail 146 to shape the climbing frame rod 145 into an arc-shaped structure that is high in the middle and low on both sides.

[0101] The technical solution of the present invention will be described in detail below with reference to specific embodiments:

[0102] 1) Place the entire machine on the field, press the start button, and the machine will begin to work. In the trenching and loosening module 3, the second motor 51 starts, which drives the worm gear 61 and worm wheel 62 to rotate through the first chain 52, causing the support 63 to drive the second chain 54 to descend counterclockwise. At the same time, the third motor 53 starts, and the second chain 54 starts moving, breaking up the soil and achieving the soil loosening effect. While the worm wheel 62 rotates counterclockwise, the transmission wheel 64 located in the middle moves the rack 67 located on the slider 65 and slide rod 66 vertically up and down, realizing the synchronous lifting and lowering of the support 63 and the trenching component 68, thus achieving the trenching and loosening function.

[0103] 2) The watering module 2 and the fertilization module 4 start simultaneously. The water pump in the water tank starts to pump water. The water pipe is guided to the designated watering position through the outlet 41 and the limiting hole 42. The water is transported to the nozzle and sprays a uniform fine water column near the trenching and loosening module. At the same time, the fourth motor 81 starts and drives the third chain 83 through the first gear 82 to rotate the feeding component 84. The fertilizer 91 in the V-shaped fertilizer storage bin 85 is slowly pushed out from the front end of the partition 92 and broken up by the second chain 54 in the trenching and loosening module 3 below, and mixed into the soil to achieve the effect of soil moistening and base fertilizer application.

[0104] 3) The first motor 32 in the chassis module starts and is connected to the last two tires 31 through the coupling 33 and the fixing parts. The whole machine moves through the wheel transmission assembly 34.

[0105] 4) The fifth motor 101 in the yam separation and covering module 5 starts and transmits torque to the drive shaft 103 through the fourth chain 102, causing the second gear 104 to rotate. The yam stalks 111 in the yam storage bin 105 are separated at equal intervals by the yam separating component 112 and fall onto the conveyor belt 113. The conveyor belt 113 is driven by the drive shaft 103. The yam stalks 111 fall into the yam slide rail 114 and further into the pre-cut trough. The covering component 115 covers the soil cut out by the troughing and loosening module 3 back into the trough, realizing the automatic sowing and covering of yams.

[0106] 5) The climbing frame pole separation component 141 located above the whole machine in the pole insertion module 6 is powered by the adjacent motor to remove the climbing frame pole 145 individually. It is guided by the climbing frame pole guide rail 142 to fall onto the climbing frame pole support component 144. The screw drives the pressure rod component 143 to rise and fall, inserting the climbing frame pole 145 into the soil. The pressure rod component 143 presses down repeatedly back and forth. After lifting, the climbing frame pole arc rail 146 rotates 180° counterclockwise, so that the climbing frame pole 145 is separated from the whole machine, realizing the function of building a climbing frame, which is convenient for yam growth.

[0107] Chassis module 1 starts, the whole machine moves forward, and the cycle is completed.
