Description

Technical Field

[0001] This application relates to the field of agricultural machinery technology, and in particular to an integrated garlic harvester. Background Technology

[0002] Garlic, as an important economic crop, occupies a wide position in agricultural production. However, in its cultivation industry, the traditional harvesting process has long relied on manual labor, requiring harvesters to bend over and squat down to dig the garlic cloves out of the soil one by one. This is not only labor-intensive and inefficient, but also highly susceptible to weather and seasonal limitations, severely restricting the large-scale and intensive development of garlic cultivation.

[0003] With the advancement of agricultural modernization, garlic harvesters have emerged to improve operational efficiency and reduce labor costs. These harvesters typically use clamping devices to quickly and continuously pull garlic cloves from the soil, significantly reducing the burden on manual labor and increasing harvesting speed. However, when using these garlic harvesters, the roots of the garlic cloves are often covered with a large amount of soil after being pulled out. If this soil is not removed in time, it will increase the workload of subsequent cleaning and is not conducive to improving harvesting efficiency. Summary of the Invention

[0004] In view of this, this application aims to propose an integrated garlic harvester to improve harvesting efficiency.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows: A garlic harvesting machine includes a vehicle body, and a front wheel, a harvesting device, a rear wheel and an engine arranged sequentially from front to back on the vehicle body; The harvesting device includes a liftable frame mounted on the vehicle body, a front shovel at the front end of the frame, a conveyor roller conveyor on the frame, two guide plates on both sides of the conveyor roller conveyor, and a leveling device at the lower end of the frame. The front shovel can scoop up garlic and soil together onto the conveyor rollers; the conveyor rollers are powered by the engine and can transport the garlic to the ground behind the frame; the two guide plates can jointly guide the garlic on the conveyor rollers to gather towards the center in the width direction of the vehicle body, so that the garlic falling on the ground can avoid the rear wheels; the leveling device can push up the protrusions on the ground to level the ground. The conveyor roller conveyor includes a plurality of spaced-apart beating rollers, each of which has a protrusion and is capable of conveying the garlic and striking it with the protrusion, so that the soil is detached from the garlic and falls below the conveyor roller conveyor.

[0006] Furthermore, the harvesting device includes a power transmission device connected to the engine drive, and each adjacent soil-beating roller is connected to the other via a gear set. The power output end of the power transmission device is connected to at least one of the soil-beating rollers.

[0007] Furthermore, the garlic harvesting machine includes a vibration device mounted on the frame; The front shovel includes a swing member pivotally connected to the front end of the frame, and a shovel body connected to the bottom end of the swing member; the vibration device is powered by the engine and can reciprocate to push and pull the swing member to vibrate the shovel body.

[0008] Furthermore, the vibration device includes a first intermediate shaft disposed on the frame, an eccentric bearing mounted on the first intermediate shaft, and a transmission rod with one end mounted outside the eccentric bearing and the other end pivotally connected to the swing member. The first intermediate shaft is connected to the engine drive.

[0009] Furthermore, the frame is provided with two mounting seats, each of which is equipped with a rotating roller. The two rotating rollers are respectively located on both sides of the front shovel in the width direction of the vehicle body, which can guide the contacting material onto the front shovel. The two rollers are driven together, and at least one of the rollers is driven together with the first intermediate shaft.

[0010] Furthermore, the leveling device includes a liftable shovel mounted on the frame, and the frame has a slide above the shovel, through which the garlic can slide to the ground behind the shovel.

[0011] Furthermore, the leveling device includes a second intermediate shaft mounted on the frame, a rotatable swing arm mounted on the second intermediate shaft, a soil-turning roller pivotally connected to the swing arm, and a first hydraulic cylinder hinged between the swing arm and the frame. The second intermediate shaft is connected to the driving roller and the turning roller respectively. The first hydraulic cylinder can drive the swing arm to rotate to adjust the height of the turning roller. The turning roller is located in front of the shovel.

[0012] Furthermore, the turning roller rotates in the same direction as the beating roller, and the turning roller has multiple blades. The blades rotate with the turning roller and can push the soil to both sides in the width direction of the vehicle body.

[0013] Furthermore, the vehicle body is provided with a downwardly extending slide rod, a slider is sleeved on the slide rod, the slider is hinged to the rear end of the frame, and a second hydraulic cylinder is hinged between the slider and the slide rod; The vehicle body is equipped with a support frame, and a third hydraulic cylinder is hinged between the support frame and the front end of the frame. The frame can change its position by being driven by the second hydraulic cylinder and the third hydraulic cylinder.

[0014] Furthermore, the front end of the vehicle body is provided with a counterweight hopper capable of holding counterweights.

[0015] Compared with related technologies, this application has the following advantages: (1) The garlic harvester described in this application uses multiple spaced-apart beating rollers to beat the garlic and use the impact force to remove the soil from the garlic, which can effectively reduce the soil attached to the garlic, reduce the workload of subsequent cleaning processes, and improve harvesting efficiency. Two guide plates guide the garlic to gather in the middle of the vehicle width direction, so that the garlic falls on the ground to form a concentrated strip. The strip avoids the driving trajectory of the rear wheel, reducing the risk of the rear wheel crushing the harvested garlic. Moreover, the garlic can be under the action of gravity with the garlic head facing down and the garlic leaves facing up. The garlic leaves cover the garlic head, making the garlic head less likely to be sunburned. The leveling device can push the ground protrusions before the garlic falls to the ground, leveling the working path, so that the garlic is finally on a flat ground. After the garlic is removed, there is no need to level the ground again, which is beneficial to the subsequent process of large-scale planting. (2) Adjacent beating rollers are connected by gear set transmission. The power transmission device drives at least one beating roller, which can drive all beating rollers to rotate synchronously. The garlic is subjected to more uniform force on the conveying roller, and the soil removal effect is better. The gear set is integrated inside the frame, with a compact layout, does not occupy extra space, and avoids straw and weeds from getting tangled in the field.

[0016] (3) The vibrating device pushes and pulls the swinging part back and forth, causing the shovel to vibrate. During the vibration process, the shovel can destroy the soil structure, reduce the resistance of shoveling soil, and make the garlic and soil more smoothly shoveled. The vibration can also make the garlic slide quickly upward along the surface of the shovel to the conveying roller, avoiding the blockage caused by the garlic accumulating at the shovel opening. (4) The first intermediate shaft drives the eccentric bearing to rotate, so that the transmission rod drives the swinging component to swing precisely. The vibration frequency and amplitude are stable, and the shovel body digs soil at a uniform depth. By replacing the eccentric bearing with different eccentricity, the vibration amplitude can be flexibly adjusted to adapt to different soil moisture and garlic varieties. The eccentric bearing and transmission rod of the vibration device are integrated at the front end of the frame, which is small in size and has a compact structure.

[0017] (5) Two rotating rollers are located on both sides of the width of the front shovel. When rotating, they can guide the garlic and soil on both sides of the front shovel towards the shovel body. It is not easy to miss the edge of the front shovel and the straw is not easy to snag on the edge of the front shovel. The rotating rollers are connected to the first intermediate shaft drive. No additional power source is required. The power is synchronously driven by the vibration device to further optimize the power distribution and reduce the number of transmission parts. The rotation direction of the rotating rollers is consistent with the material movement direction, which can play a role in pushing the material.

[0018] (6) The shovel blade is adjustable in height and can flexibly adjust the shoveling depth according to the height of the ground protrusion. The slide is located above the shovel blade. The garlic conveyed by the conveyor roller slides through the slide to the ground behind the shovel blade to form a concentrated strip. The slide outlet avoids the working area of ​​the shovel blade to avoid damage caused by contact between the garlic and the shovel blade. The ground leveled by the shovel blade provides a flat place for the garlic strips to avoid water accumulation and mold caused by uneven ground, which is suitable for the subsequent drying process. (7) When the soil turning roller rotates, it can loosen and break up the loose soil falling from the conveyor roller, and then push it to both sides. After that, it is leveled by the shovel, which has a better leveling effect. The first hydraulic cylinder adjusts the swing arm angle, and then adjusts the height of the soil turning roller. It can be adjusted according to the thickness of the soil and the soil quality to adapt to the garlic harvest with different planting densities and ensure the soil turning effect. The soil turning roller gets power from the soil hitting roller through the second intermediate shaft. The power transmission route is simple, the failure points are reduced, and it is conducive to improving the reliability of the equipment.

[0019] (8) Because of the guiding effect of the guide plate, the soil falling on the conveyor roller will be more centered. The turning roller blades will push the soil to both sides smoothly, which can disperse the soil before the shovel scrapes it, which is conducive to improving the flatness of the ground.

[0020] (9) The second hydraulic cylinder controls the slider to slide along the slide bar, and the third hydraulic cylinder connects the support frame and the front end of the frame. The second and third hydraulic cylinders work together to drive the frame to lift and tilt. By adjusting the frame height and tilt angle, the depth of the front shovel into the soil can be controlled more accurately to adapt to garlic with different planting depths.

[0021] (10) The harvesting device is concentrated in the middle of the vehicle body, the engine is located at the rear of the vehicle body, the front wheel load is small, the counterweight bucket can be loaded with sand, stones and other counterweights to avoid the vehicle body tilting up due to the front end being too light during harvesting, or the front shovel digging depth being unstable. After the counterweight is unloaded, the counterweight bucket can be used to load harvested garlic, tools, fertilizer and other materials, improving practicality and user experience.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

[0028] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0029] An embodiment of the first aspect of this application provides a garlic harvesting machine to improve harvesting efficiency.

[0030] Garlic, as an important economic crop, occupies a wide position in agricultural production. However, in its cultivation industry, the traditional harvesting process has long relied on manual labor, requiring harvesters to bend over and squat down to dig the garlic cloves out of the soil one by one. This is not only labor-intensive and inefficient, but also highly susceptible to weather and seasonal limitations, severely restricting the large-scale and intensive development of garlic cultivation.

[0031] With the advancement of agricultural modernization, garlic harvesters have emerged to improve operational efficiency and reduce labor costs. These harvesters typically use clamping devices to quickly and continuously pull garlic cloves from the soil, significantly reducing the burden on manual labor and increasing harvesting speed. However, when using these garlic harvesters, the roots of the garlic cloves are often covered with a large amount of soil after being pulled out. If this soil is not removed in time, it will increase the workload of subsequent cleaning and is not conducive to improving harvesting efficiency.

[0032] In view of this, in order to overcome the shortcomings of related technologies, the garlic harvester in this embodiment combines... Figures 1 to 4 In terms of overall design, it includes a vehicle body 1, and a front wheel 2, a harvesting device, a rear wheel 3 and an engine 4 arranged sequentially from front to back on the vehicle body 1.

[0033] The harvesting device includes a liftable frame 5 mounted on the vehicle body 1, a front shovel 6 located at the front end of the frame 5, a conveyor roller 7 mounted on the frame 5, two guide plates 8 located on both sides of the conveyor roller 7, and a leveling device 9 located at the lower end of the frame 5.

[0034] The front shovel 6 scoops up garlic and soil together onto the conveyor roller 7. The conveyor roller 7, powered by the engine 4, transports the garlic to the ground behind the frame 5. Two guide plates 8 guide the garlic on the conveyor roller 7 towards the center of the vehicle body 1 in the width direction, allowing the garlic falling to the ground to avoid the rear wheels 3. The leveling device 9 pushes aside protrusions on the ground to level it.

[0035] The conveyor roller 7 includes multiple spaced-apart beating rollers 701, each beating roller 701 having a protrusion, and each beating roller 701 can convey garlic and beat the garlic through the protrusion, so that the soil is separated from the garlic and falls below the conveyor roller 7.

[0036] Therefore, by using multiple spaced-apart beating rollers 701 to strike the garlic, the soil is detached from the garlic by the impact force, which can effectively reduce the soil attached to the garlic, reduce the workload of subsequent cleaning processes, and help improve harvesting efficiency.

[0037] Secondly, the two guide plates 8 guide the garlic to gather towards the center of the vehicle body 1, causing the garlic to fall to the ground in a concentrated strip. This strip avoids the trajectory of the rear wheels 3, reducing the risk of the rear wheels crushing the harvested garlic. Furthermore, the garlic is positioned with the bulbs facing down and the leaves facing up under gravity, with the leaves covering the bulbs and preventing them from being sunburned. The leveling device 9 can push aside any protrusions on the ground before the garlic falls, leveling the work path and ensuring the garlic is ultimately on a flat surface. After the garlic is removed, there is no need to level the ground again, which is beneficial for subsequent processes in large-scale planting.

[0038] Based on the above overview, specifically, the width of the garlic and soil scooped up by the front shovel 6 is the harvesting width of the garlic harvester. The harvesting width is greater than the outer distance between the two rear wheels 3 to prevent the rear wheels 3 from crushing unharvested garlic. The frame 5 is a rectangular frame, with guide plates 8 symmetrically arranged on the left and right sides of the frame 5 and welded to it. The upper part of the soil-beating roller 701 is embedded in the lower end of the guide plate 8, which can effectively block the garlic and prevent it from leaking out from the side.

[0039] Continue to combine Figures 1 to 4 As shown, in some exemplary embodiments, the harvesting device includes a power transmission device 10 that is driven to the engine 4, and each adjacent beating roller 701 is driven to be connected by a gear set. The power output end of the power transmission device 10 is driven to at least one beating roller 701.

[0040] Adjacent beating rollers 701 are connected by a gear set. The power transmission device 10 drives at least one beating roller 701, which in turn drives all beating rollers 701 to rotate synchronously. The garlic is subjected to more uniform force on the conveyor roller 7, resulting in better soil removal. The gear set is integrated inside the frame 5, which is compact and does not occupy extra space, thus avoiding entanglement of straw and weeds in the field.

[0041] For example, six beating rollers 701 can be set and arranged at intervals along the front and rear direction of the vehicle body 1. Adjacent beating rollers 701 are connected by a set of cylindrical spur gears so that the rotation direction of each beating roller 701 is the same, and all of them can transport garlic to the rear of the frame 5. The frame 5 is provided with a third intermediate shaft 502. The power transmission device 10 can be, for example, a right-angle reducer. Its input shaft is connected to the output shaft of the engine 4 through a drive shaft with a universal joint. The output shaft extends along one side of the width direction of the vehicle body 1 and is driven by the third intermediate shaft 502 by a sprocket and chain. The third intermediate shaft 502 is driven by a beating roller 701 below it by a sprocket and chain, so that power is transmitted from the power transmission device 10 to the beating roller 701.

[0042] Reference Figure 5 The beating roller 701 may include, for example, a roller shaft 7011, a disc 7012 welded axially to the roller shaft 7011, and a beating rod 7013 welded around the disc 7012. The beating rod 7013 is disposed protruding relative to the disc 7012 to form a protrusion for beating garlic.

[0043] See Figures 1 to 4 , Figure 6Regarding the specific harvesting method of the front shovel 6, the garlic harvester includes a vibration device 11 mounted on the frame 5. The front shovel 6 includes a swing member 602 pivotally connected to the front end of the frame 5, and a shovel body 601 connected to the bottom end of the swing member 602. The vibration device 11 receives power from the engine 4 and can reciprocate to push and pull the swing member 602 to vibrate the shovel body 601.

[0044] The vibrating device 11 reciprocates by pushing and pulling the swinging component 602, causing the shovel body 601 to vibrate. During the vibration process, the shovel body 601 can disrupt the soil structure, reduce the resistance to shoveling soil, and make the garlic shoveled and soiled more smoothly. The vibration can also make the garlic slide quickly upward along the surface of the shovel body 601 to the conveying roller 7, avoiding the blockage caused by the garlic accumulating at the shovel opening.

[0045] The shovel body 601 is arranged inclined downwards from back to front, and the front end of the shovel body 601 is equipped with a shovel blade, which can efficiently scoop up soil and garlic. The rear end of the shovel body 601 is equipped with a hollow structure, which allows the soil that has initially detached from the garlic on the shovel body 601 to fall back to the ground. Since the garlic has garlic leaves, the garlic leaves will be lifted after contacting the soil-beating roller 701 and transported by the conveyor roller 7.

[0046] Specifically, the vibration device 11 includes a first intermediate shaft 1101 mounted on the frame 5, an eccentric bearing 1102 mounted on the first intermediate shaft 1101, and a transmission rod 1103 with one end mounted outside the eccentric bearing 1102 and the other end pivotally connected to the swing member 602. The first intermediate shaft 1101 is connected to the engine 4 for transmission. The swing member 602 can be configured as a gate shape, with its lower ends connected to the shovel body 601, and its upper part arranged between the first intermediate shaft 1101 and two sets of transmission rods 1103 and eccentric bearings 1102 to improve the force transmission effect.

[0047] The first intermediate shaft 1101 drives the eccentric bearing 1102 to rotate, causing the transmission rod 1103 to drive the swinging component 602 to swing precisely. The vibration frequency and amplitude are stable, and the shovel body 601 digs soil to a uniform depth. By replacing the eccentric bearings 1102 with different eccentricities, the vibration amplitude can be flexibly adjusted to adapt to different soil moisture and garlic varieties. The eccentric bearing 1102 and transmission rod 1103 of the vibration device 11 are integrated into the front end of the frame 5, making it small in size and compact in structure. One end of the first intermediate shaft 1101 is connected to the output shaft of the right-angle reducer by a sprocket and chain drive.

[0048] In addition, to reduce the entanglement of weeds and straw on the left and right sides of the front shovel 6, the frame 5 is provided with two mounting seats 501, each with a rotating roller 12. The two rotating rollers 12 are located on both sides of the front shovel 6 in the width direction of the vehicle body 1, and can guide the material in contact onto the front shovel 6. The two rotating rollers 12 are connected by a drive, and at least one of the rotating rollers 12 is connected by a drive to the first intermediate shaft 1101.

[0049] Two rotating rollers 12 are respectively located on both sides of the width direction of the front shovel 6. When rotating, they can guide the garlic and soil on both sides of the front shovel 6 towards the shovel body 601, making it less likely to miss the edge of the front shovel 6 and preventing straw from getting caught on the edge of the front shovel 6. The rotating rollers 12 are connected to the first intermediate shaft 1101 for transmission. No additional power source is required. The power is synchronously driven by the vibration device 11, further optimizing the power distribution and reducing the number of transmission parts. The rotation direction of the rotating rollers 12 is consistent with the material movement direction, which can play a role in pushing the material.

[0050] Preferably, a synchronous shaft is provided between the two rotating rollers 12. The synchronous shaft is rotatably mounted on the frame 5, and the synchronous shaft is connected to the top of each rotating roller 12 through a bevel gear set, so as to realize that the two rotating rollers 12 rotate in opposite directions at the same speed. The rotating roller 12 located on the right side of the frame 5 is driven by a sprocket and chain to the first intermediate shaft 1101 to obtain power. The shovel body 601 is provided with a notch, and the rotating roller 12 is located in the notch, which can better gather soil, garlic, etc. towards the center.

[0051] Reference Figures 1 to 4 , Figure 7 Regarding the structure of the leveling device 9, it includes a liftable blade 901 mounted on a frame 5. The frame 5 has a slide rail 503 above the blade 901, allowing garlic to slide down to the ground behind the blade 901. The slide rail 503 can be welded between two guide plates 8. The blade 901 can have a crescent-shaped cross-section for better soil-moving performance.

[0052] With this configuration, the shovel blade 901 can be raised and lowered for flexible adjustment of the shoveling depth according to the height of the ground protrusion. The slide 503 is located above the shovel blade 901. The garlic conveyed by the conveyor roller 7 slides through the slide 503 to the ground behind the shovel blade 901, forming a concentrated strip. The outlet of the slide 503 avoids the working area of ​​the shovel blade 901, preventing damage caused by contact between the garlic and the shovel blade 901. The ground leveled by the shovel blade 901 provides a flat placement area for the garlic strips, preventing water accumulation and mold growth caused by uneven ground, and adapting to the subsequent drying process.

[0053] Secondly, the leveling device 9 also includes a second intermediate shaft 903 mounted on the frame 5, a rotatable swing arm 905 mounted on the second intermediate shaft 903, a soil-turning roller 902 pivotally connected to the swing arm 905, and a first hydraulic cylinder 904 hinged between the swing arm 905 and the frame 5. The second intermediate shaft 903 is connected to the soil-beating roller 701 and the soil-turning roller 902 respectively. The first hydraulic cylinder 904 can drive the swing arm 905 to rotate to adjust the height of the soil-turning roller 902, which is located in front of the blade 901. The angle between the swing arm 905 and the forward direction of the vehicle body 1 is an acute angle, so that the force exerted on the first hydraulic cylinder 904 by the swing arm 905 is a compressive force.

[0054] When the turning roller 902 rotates, it can loosen and break up the loose soil falling from the conveyor roller 7, and then push it to both sides. After that, the shovel 901 flattens it, resulting in a better leveling effect. The first hydraulic cylinder 904 adjusts the angle of the swing arm 905, and then adjusts the height of the turning roller 902. It can be adjusted according to the thickness of the soil being shoveled, the soil quality, etc., to adapt to garlic harvesting with different planting densities and ensure the turning effect. The turning roller 902 obtains power from the soil-beating roller 701 through the second intermediate shaft 903. The power transmission route is simple, the failure points are reduced, and it is conducive to improving the reliability of the equipment.

[0055] Because of the guiding effect of the guide plate 8, the soil falling on the conveyor roller 7 will be positioned more centrally. Therefore, in some embodiments, the turning roller 902 rotates in the same direction as the pounding roller 701. The turning roller 902 has multiple blades 9021, which rotate with the turning roller 902 and can push the soil to both sides in the width direction of the vehicle body 1. The blades 9021 of the turning roller 902 push the soil to both sides smoothly, which can disperse the soil before the shovel 901 scoops it up, which helps to improve the leveling effect of the ground.

[0056] Specifically, the second intermediate shaft 903 is connected to both the beating roller 701 and the turning roller 902 via sprocket and chain drive. The blades 9021 on the turning roller 902 are fan-shaped, with two blades forming a group, and multiple groups of blades 9021 are spaced apart on the turning roller 902. The blades 9021 on the turning roller 902 are symmetrically arranged on the left and right sides. When the turning roller 902 rotates, the contact surface between the blades 9021 and the soil pushes the soil to both sides, dispersing the soil in the middle to facilitate the scraper 901 scooping up the protruding soil and distributing it to the lower positions on both sides.

[0057] Secondly, the scraper 901 is equipped with an upwardly extending connecting rod, and the frame 5 is equipped with a connecting cylinder that matches the shape of the connecting rod. The connecting rod has multiple interlocking holes, and bolts are screwed onto the connecting cylinder. After adjusting the height of the scraper 901, the threaded end of the bolt is screwed into the corresponding hole to fix the height of the scraper 901 relative to the frame 5. There can be four connecting rods, arranged on both sides of the scraper 901, avoiding the slide rail 503.

[0058] Regarding the lifting and lowering mechanism of the frame 5 on the vehicle body 1, the vehicle body 1 is equipped with a downwardly extending slide rod 101. A slider 102 is fitted onto the slide rod 101, and the slider 102 is hinged to the rear end of the frame 5. A second hydraulic cylinder 103 is hinged between the slider 102 and the slide rod 101. The vehicle body 1 is equipped with a support frame 104, and a third hydraulic cylinder 105 is hinged between the support frame 104 and the front end of the frame 5. The frame 5 can change its position by being driven by the second hydraulic cylinder 103 and the third hydraulic cylinder 105.

[0059] The second hydraulic cylinder 103 controls the slider 102 to slide along the slide rod 101. The third hydraulic cylinder 105 connects the support frame 104 to the front end of the frame 5. The second hydraulic cylinder 103 and the third hydraulic cylinder 105 work together to achieve the lifting and tilting angle adjustment of the frame 5. By adjusting the height and tilting angle of the frame 5, the depth of the front shovel 6 into the soil can be controlled more accurately to adapt to garlic with different planting depths.

[0060] In addition, in order to improve the driving stability and harvesting stability of the garlic harvester, the front of the vehicle body 1 is equipped with a counterweight bucket 13 that can hold counterweights.

[0061] The harvesting device is concentrated in the middle of the vehicle body 1, the engine 4 is located at the rear of the vehicle body 1, the front wheel 2 has a small load, and the counterweight bucket 13 can be loaded with sand, stones and other counterweights to prevent the vehicle body 1 from tilting up due to the front end being too light during harvesting, or the front shovel 6 from digging soil at an unstable depth. After the counterweight is unloaded, the counterweight bucket 13 can be used to load harvested garlic, tools, fertilizer and other materials, improving practicality and user experience.

[0062] In practical implementation, a hydraulic pump station can be installed on the vehicle body 1. The hydraulic pump station is powered by the engine 4. The first hydraulic cylinder 904, the second hydraulic cylinder 103, and the third hydraulic cylinder 105 are all controlled by the hydraulic pump station to control the harvesting device. The vehicle body 1 is equipped with a driver's cab and a ladder for the driver to climb into the cab.

[0063] Secondly, all parts using sprocket and chain drives in this application can be replaced with a combination of pulleys and belts or a combination of synchronous pulleys and synchronous belts. All transmission structures in this application are equipped with protective covers to prevent external debris from interfering with the transmission. To demonstrate the specific form of the transmission structure, the protective covers are not shown in the accompanying drawings of this application.

[0064] In addition, the front wheel 2 of this application has a steering function, which can be achieved by setting a hydraulic steering cylinder and controlling the corresponding hydraulic valve through the steering wheel. The specific setting can be referred to the relevant content in the prior art, and will not be repeated in this application.

[0065] The garlic harvester of this embodiment adopts the above design. It uses multiple spaced-apart beating rollers 701 to beat the garlic and use the impact force to remove the soil from the garlic. This can effectively reduce the soil attached to the garlic, reduce the workload of subsequent cleaning processes, and help improve harvesting efficiency.

[0066] Simultaneously, two guide plates 8 guide the garlic to gather towards the center of the vehicle body 1, causing the garlic to fall to the ground in a concentrated strip. This strip avoids the trajectory of the rear wheels 3, reducing the risk of the rear wheels crushing the harvested garlic. Furthermore, the garlic, under the influence of gravity, is positioned with the bulbs facing down and the leaves facing up, with the leaves covering the bulbs and preventing them from being sunburned. The leveling device 9 can push aside any protrusions on the ground before the garlic lands, leveling the work path and ensuring the garlic is ultimately on a flat surface. After the garlic is removed, there is no need to level the ground again, which is beneficial for subsequent processes in large-scale planting.

[0067] The above descriptions are merely some embodiments of this application and are not intended to limit this application. The technical features or structures in the foregoing different embodiments can be arbitrarily combined to form other specific technical solutions as needed. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of the claims of this application.
