Description

Technical Field

[0001] This invention relates to the field of agricultural machinery, and in particular to a leek planting device and planting method. Background Technology

[0002] Chives, a widely cultivated perennial root vegetable in my country, have unique characteristics in cultivation and management due to their distinctive pungent aroma and the physiological phenomenon of "jumping roots." "Jumping roots" refers to the physiological phenomenon where, with each year's division, new roots grow layer by layer from above the original bulb, causing the root system to gradually move upwards. The chive root system moves upwards by approximately 1.5-2 cm each year. If soil is not promptly used for hilling, the exposed roots will face problems such as sunburn, frost damage, and excessive water evaporation. Ridging and hilling are essential agronomic management measures implemented to address the jumping root characteristic of chives. The core purpose of this operation is to mechanically or manually gather the soil between the plants to form a mound about 2-3 cm high around the base of the chive plant. This hilling and hilling operation is typically performed 2-3 times throughout the chive's growth cycle.

[0003] However, current hilling and ridging operations mainly rely on manual labor, which presents the following prominent problems: First, in traditional hilling and ridging operations, farmers need to loosen the soil between plants and then gather the soil from both sides towards the middle; this leads to high labor intensity and low work efficiency. Second, the quality of manual hilling is highly dependent on the operator's skill level; inexperienced operators often result in uneven hilling and inconsistent ridge height, leaving some roots exposed; more seriously, when manually digging with a hoe, soil clods fly or the hoe directly hits the leek plant, easily causing mechanical damage to the leaves, creating wounds for pathogens to enter and increasing the risk of diseases such as gray mold and blight.

[0004] In response to the aforementioned problems of high labor intensity, low efficiency, unstable work quality, and easy damage to plants, this invention designs a chive planting device and planting method. Summary of the Invention

[0005] The purpose of this invention is to provide a chive planting device and planting method that can solve the problems of high labor intensity, low efficiency, unstable operation quality, and easy damage to plants mentioned above.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a chive planting device, comprising an agricultural vehicle, a soil-loosening component, and a ridging and hilling mechanism; the agricultural vehicle is fixedly equipped with a soil-loosening component for loosening the soil; the agricultural vehicle is also fixedly equipped with a ridging and hilling mechanism for pushing the loosened soil to the roots of the chives; the purpose is to achieve integrated operation of soil-loosening and ridging and hilling, thereby improving work efficiency. The ridging and soil-filling mechanism includes a mounting base, a pair of ridging and soil-filling plates, and a drive assembly, forming the core framework of the mechanism. Two central shafts are symmetrically fixed on both sides of the bottom of the mounting base. The circumferential side of each central shaft rotates with the central area of ​​one ridging and soil-filling plate. The pair of ridging and soil-filling plates are symmetrical about the vertical plane containing the center line of the mounting base. This provides a stable fulcrum for the ridging and soil-filling plates and ensures symmetrical swinging motion of the left and right symmetrical plates, resulting in relatively uniform soil filling. The drive assembly is connected to the pair of ridging and soil-filling plates and drives them to swing back and forth. The drive assembly provides power to drive the ridging and soil-filling plates to complete the soil-gathering action.

[0007] As a preferred embodiment of the present invention, the front end of the soil-raising and mounding board is configured as a soil-gathering section; the soil-gathering section adopts a long strip board structure, and the long strip board structure is also provided with an arc-shaped clearance section; the top of the soil-gathering section is also provided with several layers of protective baffles for preventing soil splashing; anti-rebound baffles are also provided on the inner side of the two protective baffles at the bottom layer; the purpose of the design is to increase the contact area with the loosened soil through the long strip board structure and improve the soil-gathering efficiency; the arc-shaped clearance section is used to avoid the roots and stems of the chives and avoid damage to the plants; the protective baffles are used to reduce the impact of soil clods on the chive plants, reduce leaf damage, and thus reduce the risk of disease occurrence; when the soil-gathering section gathers soil quickly, the soil clods on its inner side are easily impacted quickly and cause them to tilt upwards or even rebound and splash out; the anti-rebound baffles are used to reduce the soil clods that rebound when impacted quickly.

[0008] As a preferred embodiment of the present invention, the middle part of the ridging and hilling board is configured as a swinging part; the rear part of the ridging and hilling board is configured with a first hinge seat; a height plate for adjusting the height difference is fixedly connected between the front end of the swinging part and the rear end of the soil gathering part; the purpose is to divide the ridging and hilling board into functional zones, the swinging part swings around the central axis, the first hinge seat is used to connect the drive end of the drive component, and the height plate is used to adapt to the height difference between the swinging part and the soil gathering part, the root of the leek, and the loosened soil, so as to adapt to the height difference between the drive component in the agricultural vehicle and the root of the leek, and also to provide sufficient height space for the agricultural vehicle and its components to pass over the leek, so as to avoid spatial interference between the drive component and other components and the top of the leek during startup and operation, resulting in pinching, damage, etc.

[0009] As a preferred embodiment of the present invention, the driving assembly includes an electric telescopic rod, a reciprocating support, and a connecting rod. The mounting base has the electric telescopic rod fixedly installed at the midpoint behind the two central shafts, placing the power source in the middle position to ensure the symmetry of its left and right driving forces. The telescopic end of the electric telescopic rod is fixedly installed with a reciprocating support, and both ends of the reciprocating support are provided with second hinge seats. The second hinge seats transmit the linear motion of the electric telescopic rod to the reciprocating support seats and connect with the connecting rods located at the left and right positions. Each second hinge seat is hinged to the rear end of the connecting rod. The front end of each connecting rod is hinged to a first hinge seat on the swinging part. The purpose is to convert the forward and backward linear motion of the reciprocating support into the swinging motion of the ridge-supporting and soil-covering board through the connecting rod.

[0010] As a preferred embodiment of the present invention, the bottom surface of the mounting base is fixedly installed with a first limiting post on each side of the swinging part to prevent the swinging part and the connecting support rod from hinged to the same straight line, which can prevent the drive component from moving to the dead point position and getting stuck or unable to reset; the bottom surface of the mounting base is fixedly installed with a second limiting post on each side of the swinging part to prevent the two soil gathering parts from being clamped too tightly, which can prevent the soil gathering parts from closing too much and damaging the leek plants or causing excessive soil compaction. The bottom surface of the mounting base is also fixedly installed with a third limiting post on the front side of the reciprocating support to limit the maximum extension length of the electric telescopic rod; the bottom surface of the mounting base is fixedly installed with a fourth limiting post on the rear side of the reciprocating support to limit the maximum retraction length of the electric telescopic rod. Its function is not only to precisely control the stroke range of the electric telescopic rod and avoid damage to the mechanism caused by overtravel, but also to design a double limiting protection mechanism.

[0011] As a preferred embodiment of the present invention, the soil-cutting assembly is located in front of the ridging and hilling mechanism; the soil-cutting assembly includes a transverse soil-cutting wheel assembly, which includes a first soil-cutting wheel and a first wheel seat; the top of the first wheel seat is fixedly mounted on an agricultural vehicle, and the bottom of the first wheel seat is rotatably connected to the first soil-cutting wheel, with transverse soil-cutting blades arranged in a circular array on the circumference of the first soil-cutting wheel; before ridging and hilling, the soil is first transversely cut to break up the compacted soil layer, creating favorable conditions for subsequent soil gathering.

[0012] As a preferred embodiment of the present invention, the soil-cutting assembly includes a longitudinal soil-cutting wheel assembly, which includes a second soil-cutting wheel and a second wheel seat. The top of the second wheel seat is fixedly mounted on an agricultural vehicle, and the bottom of the second wheel seat is rotatably connected to the second soil-cutting wheel. Several annular soil-cutting blades are fixedly connected side by side on the circumferential side of the second soil-cutting wheel. It performs longitudinal cutting on the soil, further refining the soil clods, and cooperates with the transverse soil-cutting wheel assembly to achieve multi-dimensional soil breaking and improve the loosening effect.

[0013] As a preferred technical solution of the present invention, an elastic pressure plate for controlling the digging depth is also installed between the agricultural vehicle and the transverse digging wheel assembly, so as to realize the adjustment of the digging depth and the adaptive adjustment effect through elastic pressure. The transverse tiller assembly is fixedly installed on the bottom surface of the elastic pressure plate; the agricultural vehicle is hinged to one end of the elastic pressure plate, and a U-shaped limiting rod is fixedly installed on the other end of the elastic pressure plate; a compression spring is fixedly connected between the top surface of the elastic pressure plate and the agricultural vehicle; the transverse tiller assembly can swing up and down around the hinge point through the compression spring and its hinge structure, the compression spring provides downward pressure, so that the transverse tiller assembly always adheres to and presses into the soil to a certain depth, and the U-shaped limiting rod limits its swing range; The U-shaped limiting rod has a threaded adjusting column at the other end of the bottom surface of the elastic pressure plate for adjusting the hinge angle and the digging depth; by rotating the threaded adjusting column, the maximum tilt angle of the elastic pressure plate is changed, thereby precisely controlling the maximum digging depth of the transverse digging wheel assembly.

[0014] As a preferred embodiment of the present invention, the agricultural vehicle is also fixedly equipped with a battery pack, and the transverse tiller assembly has a built-in drive motor for driving. The drive motor is also connected to the second tiller. Both the drive assembly and the drive motor are powered by the battery pack, providing a power source independent of the agricultural vehicle and reducing the complexity of the transmission system, freeing it from the constraints of an external power source and improving the flexibility of field operations. The mounting base is fixedly installed with a protective support plate for protection and guidance below the drive assembly via a connecting column. The top surface of the protective support plate slides in contact with the bottom surface of the reciprocating support, the bottom surface of the connecting rod, and the bottom surface of the swing part. Its function is to protect the drive assembly from soil intrusion and to provide guidance support for the reciprocating support, the connecting rod, and the swing part, ensuring stable operation.

[0015] A method for cultivating chives using a chive cultivation device includes the following steps: Step 1: First, align the soil-digging component with the gaps between each row of chives in the chive field to ensure accurate digging and avoid damaging the chive roots. Step 2: Drive the agricultural vehicle intermittently through the leek field by manually pushing or starting the power source, control the work rhythm, and create conditions for subsequent intermittent soil covering. Step 3: The soil-loosening component begins to loosen the soil in the gaps on both sides of the row of chives in a passive or active and continuous manner, breaking up and softening the soil on both sides of the chives before backfilling, making it easier to gather the soil later. Step 4: When the farm vehicle is stationary, the ridging and hilling mechanism is activated simultaneously, driving a pair of ridging and hilling plates to swing symmetrically and synchronously, thereby pushing the loose soil on both sides of the row of chives to the roots of the chives, and then quickly unfolding after pushing to achieve the reset state; the hilling operation of the current clump of chives is completed when the farm vehicle is stopped, ensuring accurate hilling. Step 5: When the ridging and hilling mechanism is in the reset state, the agricultural vehicle continues to advance a distance of one plant spacing, so that the ridging and hilling mechanism is aligned with the next clump of chives in the row to push and gather them together, realizing the coordination of intermittent advancement and intermittent hilling, ensuring that each clump of chives can be accurately hilled and increasing the amount of soil pushed to the roots of the chives; repeat steps 3 and 4.

[0016] The present invention has the following beneficial effects: 1. This invention integrates the soil-digging component and the ridging and hilling mechanism onto the same agricultural vehicle, forming a complete "digging-soil-gathering" operation chain. The soil-digging component pre-cuts and breaks up the soil between the rows of chives, and the ridging and hilling mechanism then precisely pushes the loosened soil to the roots of the chives. The two work in synergy and seamless connection. At the same time, the ridging and hilling mechanism uses a pair of ridging and hilling plates symmetrically arranged with the center line of the mounting base as the plane of symmetry. The drive component drives them to swing back and forth, so that the pair of left and right ridging and hilling plates synchronously gather the soil inward. This symmetrical swinging design ensures that the amount of soil pushed from both sides of the chive row tends to be consistent, and the resulting soil ridges are of uniform height and regular shape. It has the advantages of automated operation, high efficiency, good quality and stability, and less damage to plants, effectively solving the quality problems of uneven left and right sides and uneven ridge shape in manual hilling.

[0017] 2. This invention employs a segmented structure design for the ridging and hilling board, consisting of three sections: a front soil-gathering section, a middle swaying section, and a rear first hinge seat. When the ridging and hilling board sways inward to gather soil, the arc-shaped clearance section gently surrounds the leek stem, pushing the soil around the roots while avoiding direct impact or compression of the leek plant. Compared to traditional flat soil-pushing boards or manual soil throwing with a hoe, the arc-shaped clearance structure reduces mechanical damage to the plant by more than 90%, as well as splash damage and the risk of disease, thus reducing the risk of disease infection caused by wounds from the source. It has the advantages of gently gathering soil and avoiding plant splash damage and disease risks.

[0018] 3. The mounting base of the present invention is equipped with multiple limit protection mechanisms and elastic pressure plates, which have the advantages of preventing jamming, avoiding damage from excessive clamping, preventing damage to the mechanism from overtravel movement, and precise adjustment of digging depth.

Detailed Implementation

[0021] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0022] Example 1

[0023] Please see as follows Figures 1 to 5As shown, this embodiment of the present invention provides a chive planting device, including an agricultural vehicle 1, a soil-digging component 2, and a ridging and hilling mechanism 3. The agricultural vehicle 1 is a four-wheeled motor vehicle powered by a diesel engine, and one of its main uses is as a four-wheeled motor vehicle for field operations. The soil-digging component 2 and the ridging and hilling mechanism 3 are fixedly mounted on the rear end of its frame via a mounting plate, and the soil-digging component 2 is located in front of the ridging and hilling mechanism 3.

[0024] Among them, such as Figure 2 As shown, the ridging and hilling mechanism 3 includes a mounting base 301, a pair of ridging and hilling plates 302, and a drive assembly 303. The mounting base 301 is fixedly mounted on the frame of the agricultural vehicle 1 by bolts. Two central shafts 304 are symmetrically welded to the bottom sides of the mounting base 301, and a ridging and hilling plate 302 is rotatably mounted on each central shaft 304. The two ridging and hilling plates 302 are arranged symmetrically from left to right with the vertical plane containing the center line of the mounting base 301 as the plane of symmetry.

[0025] Among them, such as Figure 3 , Figure 4 and Figure 8 As shown, the ridging and soil-building board 302 consists of three parts: a soil-gathering part 3021 at the front end, a swinging part 3023 in the middle, and a first hinge seat 3024 at the rear. The soil-gathering part 3021 adopts a long strip board structure, with an arc-shaped clearance part 3022 in the middle to avoid the leek stems when gathering soil. The top of the soil-gathering part 3021 is also equipped with three layers of protective baffles 3026 to prevent soil splashing, thereby reducing damage and lowering the risk of disease. On the inner side of each of the two protective baffles 3026 at the bottom layer, there is an anti-rebound baffle. Plate 3027 further reduces the amount of splashing soil caused by impact and rebound due to rapid soil gathering; the middle area of ​​the swing part 3023 has a shaft hole that rotates with the central shaft 304, and the bottom of the central shaft 304 has a pin; the front end of the swing part 3023 and the rear end of the soil gathering part 3021 are fixedly connected by a height plate 3025. The height plate 3025 is used to solve the height difference problem between the soil gathering part 3021 and the swing part 3023, so as to avoid the frame and the soil-raising mechanism 3 being too low and bending the chives, or even causing damage.

[0026] Among them, such as Figure 3As shown, the drive assembly 303 includes an electric telescopic rod 3031, a reciprocating support 3032, and two connecting rods 3033. The electric telescopic rod 3031 is a model that supports stroke adjustment. The electric telescopic rod 3031 is fixedly installed in the middle of the bottom surface of the mounting base 301, located behind the two central shafts 304. The telescopic end of the electric telescopic rod 3031 is fixedly installed with the reciprocating support 3032. Each end of the reciprocating support 3032 is provided with a second hinge seat 3034. Each second hinge seat 3034 is hinged to the rear end of a connecting rod 3033, and the front end of the connecting rod 3033 is hinged to the first hinge seat 3024 on the corresponding side ridge-supporting and soil-covering plate 302.

[0027] Among them, such as Figure 3 As shown, to prevent the mechanism from moving to the dead position or overtraveling, the bottom surface of the mounting base 301 is provided with multiple threaded blind holes and limit posts, and the limit posts are all threaded to the bottom surface of the mounting base 301, as follows: ① A first limiting post 305 is provided on each side of the swing part 3023, and a total of four first limiting posts 305 are used to limit the hinge point position of the swing part 3023 and the connecting support rod 3033 to prevent it from moving to the dead point position and getting stuck.

[0028] ②A second limiting post 306 is provided on each side of the swing part 3023, and a total of four second limiting posts 306 are used to limit the minimum distance between the two soil gathering parts 3021 to prevent the chives from being damaged by excessive clamping.

[0029] ③ Two third limiting posts 307 are provided on the front side of the reciprocating support 3032 to limit the maximum extension length of the electric telescopic rod 3031.

[0030] ④ Two fourth limiting posts 308 are provided on the rear side of the reciprocating support 3032 to limit the maximum retraction length of the electric telescopic rod 3031.

[0031] Among them, such as Figure 5 As shown, the mounting base 301 is fixedly mounted with a protective support plate 309 below the drive assembly 303 via a connecting column. The top surface of the protective support plate 309 slides in cooperation with the bottom surface of the reciprocating support 3032, the bottom surface of the connecting rod 3033, and the bottom surface of the swing part 3023, respectively, to play a protective and guiding support role.

[0032] Among them, such as Figure 2As shown, the soil-shaving assembly 2 includes a transverse soil-shaving wheel assembly 201 and a longitudinal soil-shaving wheel assembly 202. The transverse soil-shaving wheel assembly 201 includes a first soil-shaving wheel 2011 and a first wheel seat 2012. The top of the first wheel seat 2012 is mounted on the rear end of the frame of the agricultural vehicle 1, and the bottom of the first wheel seat 2012 is rotatably connected to the first soil-shaving wheel 2011. The circumferential side of the first soil-shaving wheel 2011 has a plurality of transverse soil-shaving blades 2013 arranged in a circular array. The longitudinal soil-shaving wheel assembly 202 includes a second soil-shaving wheel 2021 and a second wheel seat 2022. The top of the second wheel seat 2022 is fixedly mounted on the agricultural vehicle 1, and the bottom of the second wheel seat 2022 is rotatably connected to a second soil-shaving wheel 2021. The second shoveling wheel 2021 has three annular shoveling blades 2023 fixedly connected side by side on its circumference. The transverse shoveling wheel assembly 201 has a built-in drive motor for driving, which is also connected to the second shoveling wheel 2021 for transmission. The battery pack serves as the power source for the drive motor and the electric telescopic rod 3031, and provides power to the transverse shoveling wheel assembly 201 and the longitudinal shoveling wheel assembly 202. The drive motor is a small DC motor. Using shoveling wheels with a drive diameter of 20-30cm, the required power is between 100-300W for lightly loaded soil and 400-600W for compacted soil.

[0033] The working principle of this embodiment is as follows: During operation, the appropriate soil-digging depth is first determined based on the plant spacing and ridge height requirements for leeks. Then, the agricultural vehicle 1 is started and driven forward, while the drive motor is started to drive the transverse soil-digging wheel assembly 201 and the longitudinal soil-digging wheel assembly 202, causing the first soil-digging wheel 2011 and the second soil-digging wheel 2021 to rotate. The transverse soil-digging blade 2013 and the annular soil-digging blade 2023 cut and break up the soil between the rows of leeks in multiple dimensions. When the high-efficiency mode is used, the agricultural vehicle 1, drive motor, and electric telescopic rod 3031 all operate continuously. However, it is necessary to increase the minimum distance between the two soil-gathering parts 3021 in the ridging and soil-building mechanism 3, which means adjusting the reciprocating stroke of the electric telescopic rod 3031 and the installation position of the third limit post 307 accordingly. The travel speed of the agricultural vehicle 1 is also adjusted so that when it travels one plant spacing, the two soil-gathering parts 3021 also complete a complete pushing action synchronously. Due to the continuous operation, the ridging and soil-building plate 302 will lose some soil and not gather it to the inside. Therefore, the amount of soil pushed to the roots of the leeks will also be reduced.

[0034] Example 2

[0035] This embodiment is basically the same as Embodiment 1, except that the drive component 303 uses a hydraulic cylinder instead of the electric telescopic rod 3031, which is suitable for large farms and other operation scenarios that require greater thrust.

[0036] Example 3

[0037] This embodiment is basically the same as Embodiment 1, except that: Figure 6 As shown, the soil-scraping component 2 only includes the transverse soil-scraping wheel assembly 201, which is suitable for planting areas with relatively loose soil.

[0038] Example 4

[0039] This embodiment provides a more preferred technical solution based on Embodiment 3, such as... Figure 7 As shown, an elastic pressure plate 4 is hinged between the agricultural vehicle 1 and the transverse tiller assembly 201. The elastic pressure plate 4 is used to control the tilling depth. The transverse tiller assembly 201 is fixedly installed on the bottom surface of the elastic pressure plate 4. One end of the agricultural vehicle 1 is hinged to the elastic pressure plate 4, and a U-shaped limiting rod 5 is fixedly installed on the other end of the elastic pressure plate 4. A compression spring 6 is fixedly connected between the top surface of the elastic pressure plate 4 and the agricultural vehicle 1. The compression spring 6 is always in a compressed state, applying downward pressure to the elastic pressure plate 4. An adjusting screw 7 is threadedly connected to the other end of the U-shaped limiting rod 5 on the bottom surface of the elastic pressure plate 4. By rotating the adjusting screw 7, the initial angle of the elastic pressure plate 4 can be adjusted, thereby precisely controlling the tilling depth of the transverse tiller assembly 201. In this embodiment, the transverse tiller assembly 201 and the longitudinal tiller assembly 202 are not connected simultaneously. The reason for this assembly is that one elastic pressure plate 4 cannot simultaneously ensure that the bottoms of both the transverse tiller assembly 201 and the longitudinal tiller assembly 202 are in good contact with the ground soil, as there will be a height difference between them on one elastic pressure plate 4. If depth adjustment is required, two sets of elastic pressure plates 4 need to be installed, each independently adjusting and controlling the height of the transverse tiller assembly 201 and the longitudinal tiller assembly 202. Moreover, the longitudinal tiller assembly 202 mainly assists in further cutting and breaking up the soil loosened by the transverse tiller assembly 201. Even if an elastic pressure plate 4 is installed between the agricultural vehicle 1 and the longitudinal tiller assembly 202, the effect will not be significantly improved. Therefore, it is not necessary to install two elastic pressure plates 4. This embodiment is mainly suitable for planting areas with many uneven soil surfaces.

[0040] Example 5

[0041] This embodiment is basically the same as Embodiment 1, except that: the agricultural vehicle 1 is a hand-held cart; the operating cycle or pattern of the electric telescopic pole 3031 is set, and the farmer only needs to control the speed of the hand-held cart to achieve a relatively precise soil-building operation.

[0042] Example 6

[0043] Based on Embodiment 1, this embodiment provides a method for planting chives using a planting device, such as... Figure 3As shown, when using the high-precision mode, the agricultural vehicle 1 stops when it reaches the location where the leeks need to be mounded with soil. At this time, the electric telescopic rod 3031 is activated, causing its telescopic end to reciprocate. When the electric telescopic rod 3031 extends, it pushes the reciprocating support 3032 forward. The reciprocating support 3032, through the connecting rod 3033, pushes the two mounding plates 302 to swing inward around the central axis 304, and the soil-gathering part 3021 pushes the loosened soil to the base of the leeks. When the electric telescopic rod 3031 retracts, it pulls the reciprocating support 3032 backward. The mechanism 3 moves by pulling the two ridge-raising and soil-covering plates 302 outwards and resetting them through the connecting rod 3033. Throughout the process, the first limiting post 305 prevents the hinge point from moving to the dead point position, the second limiting post 306 prevents the soil-collecting part from clamping too tightly, and the third limiting post 307 and the fourth limiting post 308 limit the travel range of the electric telescopic rod 3031. After each clump of chives is covered with soil, the ridge-raising and soil-covering mechanism 3 resets, and the agricultural vehicle 1 continues to move forward one plant spacing distance, aligns with the next clump of chives, and repeats the above-mentioned digging and soil-covering process until the entire row of chives is completed.

[0044] In this system, the agricultural vehicle 1 stops precisely at the location of each clump of chives using an intermittent operation mode. Then, an electric telescopic rod 3031 drives symmetrically arranged ridging and hilling plates 302 to swing back and forth, gently pushing the loosened soil towards the chive roots. Compared to existing continuous hilling machinery, this solution fundamentally solves the inherent contradiction that traditional equipment cannot adapt to the agronomical requirements of "fixed-point hilling" for chives. It avoids over-hilling in unnecessary areas and under-hilling in key locations, achieving precise alignment and selective hilling for each clump of chives. The core of the four-wheeled vehicle's "intermittent movement" lies in the precise start-stop control of the drive system. It employs four-motor independent drive technology, enabling millisecond-level adjustment of the torque of all four wheels for instantaneous start-stop action. The precise positioning function is achieved by real-time monitoring of wheel speed and position via encoders, ensuring precise control of the travel distance and guaranteeing that the stopping position is aligned with each clump of chives.
