Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery, and specifically relates to a garlic hoeing machine with a lifting mechanism. Background Technology

[0002] When hoeing garlic, the garlic hoe blade needs to be inserted into the ground to remove the garlic. When the garlic hoe needs to turn, the garlic hoe blade will generate great resistance when it comes into contact with the ground, making it difficult for the garlic hoe to turn.

[0003] Because garlic leaves can get tangled between the ridges, a ridge divider needs to be installed at the front of the garlic hoeing machine to separate the garlic leaves by contacting the ground, thus clearing obstacles for the walking mechanism. When turning, if the handle is raised, the ridge divider will extend into the soil, which will also make it difficult for the garlic hoeing machine to turn.

[0004] To ensure that the garlic hoe blade maintains a constant depth when encountering uneven ground, the walking mechanism is designed to adjust its height according to changes in terrain. However, when turning and raising the handrail, the walking mechanism will wobble, causing the front end of the walking mechanism to tilt downwards, making it difficult to lift off the ground and making turning inconvenient.

[0005] To address this issue, our company has developed a garlic hoe with a lifting mechanism that allows for easy turning during use. Utility Model Content

[0006] To address the aforementioned problems, this utility model designs a garlic hoeing machine with a lifting mechanism, including a support frame. An engine and a transmission mechanism are mounted on the support frame. The engine is driven by the transmission mechanism, which in turn drives a walking mechanism and a garlic hoeing blade. A mounting base is rotatably connected to the support frame, and the garlic hoeing blade is rotatably connected to the mounting base. A lifting mechanism is rotatably connected to the mounting base. A limiting mechanism is detachably connected to the lifting mechanism on the support frame. A lifting channel is provided at the end of the support frame furthest from the engine.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: The garlic hoe is connected to a lifting mechanism. When a turn is needed, the lifting mechanism is raised, causing it to rotate on the support frame, thereby moving the mounting base upwards. This, in turn, moves the garlic hoe upwards within the lifting channel. After a certain distance from the ground, a limiting mechanism engages with the lifting mechanism to limit its movement, allowing the garlic hoe to turn at a certain height above the ground, preventing it from contacting the ground and enabling easy turning. When the garlic hoe is to work again, the limiting mechanism separates from the lifting mechanism, causing it to move downwards. This allows the mounting frame to move the garlic hoe downwards within the lifting channel, bringing it into contact with the ground for garlic hoeing.

[0008] Furthermore, the mounting base includes a base, on which a tool mounting shaft, a support shaft, and a connecting shaft are provided. Fixing members are provided on both sides of the base. The garlic hoe is disposed between the fixing members and the base. The garlic hoe is rotatably connected to the tool mounting shaft, and the connecting shaft is rotatably connected to the support frame.

[0009] The fixing component is connected to the tool mounting shaft, the connecting shaft, and the support shaft, and the lifting mechanism is connected to the base;

[0010] Preferably, the base and the fastener are plate-shaped.

[0011] The beneficial effect of adopting the above-mentioned further technical solution is that when the lifting mechanism pulls the mounting base to move, the connecting shaft rotates along the support frame, thereby driving the garlic hoe blade to move up and down;

[0012] The garlic hoe is rotatably mounted on the blade mounting shaft. The fixing component limits the movement of both sides of the blade mounting shaft, preventing the garlic hoe from falling off. It is connected to the base via a lifting mechanism. The fixing component is connected to the blade mounting shaft, connecting shaft, and support shaft, thus ensuring the stability of the lifting mechanism when the garlic hoe is lifted. The plate-shaped base and fixing component make the mounting base lighter, which is beneficial for the lifting mechanism.

[0013] Furthermore, the lifting mechanism includes a steering wrench and a lifting link, the lifting link being rotatably connected to the steering wrench and the mounting base respectively;

[0014] The steering wrench is provided with several retaining holes, and the limiting mechanism cooperates with the retaining holes to retain the device.

[0015] The beneficial effects of adopting the above-mentioned further technical solution are as follows: the farmer turns the steering wrench, which drives the lifting linkage to move, and the lifting linkage drives the garlic hoe blade in the mounting base to move vertically in the lifting channel. The limiting mechanism cooperates with the locking hole on the steering wrench to lock the garlic hoe blade. When the garlic hoe blade moves to the appropriate position, it is limited, so that the garlic hoe blade turns while maintaining a certain distance from the ground.

[0016] Furthermore, the limiting mechanism includes a first limiting plate, a second limiting plate, a limiting cylinder, and a telescopic device. The first limiting plate and the second limiting plate are respectively disposed on both sides of the lifting wrench. A rotating shaft is disposed on the first limiting plate and the second limiting plate. The lifting wrench is connected to the rotating shaft. The first limiting plate is provided with a first limiting hole, and the second limiting plate is provided with a second limiting hole. The limiting cylinder is disposed on the side of the first limiting plate away from the lifting wrench. The limiting cylinder communicates with the first limiting hole. The first limiting plate and the second limiting plate are connected to the support frame.

[0017] The telescopic device includes a clamping post, an elastic element, and a pull rope. The limiting cylinder includes a bottom wall and a side wall. The bottom wall is located on the side away from the limiting plate. The pull rope passes through the bottom wall and is connected to the clamping post. The clamping post is slidably disposed inside the limiting cylinder. The elastic element is disposed between the clamping post and the bottom wall. The clamping post cooperates with the clamping hole for clamping.

[0018] Preferably, the length of the retaining post is greater than the distance between the first limiting hole and the second limiting hole;

[0019] The beneficial effects of adopting the above-mentioned further technical solution are as follows: When the steering wrench rotates on the pivot between the first and second limiting plates, the clamping pin of the telescopic device fits tightly with the steering wrench. When the clamping hole is between the first and second limiting holes, under the elastic action of the elastic element, the clamping pin moves from inside the limiting cylinder into the clamping hole, thereby clamping the steering wrench and raising the garlic hoe to a suitable position. When the length of the clamping pin is greater than the distance between the first and second limiting holes, the clamping pin can penetrate through the first and second limiting holes and the clamping hole, thereby clamping the steering wrench and making the clamping stability of the clamping pin and the steering wrench highly stable.

[0020] Furthermore, the support frame is provided with a handrail, which is located on the side away from the engine, and a handbrake is provided on the handrail, which is connected to a pull rope.

[0021] The beneficial effects of adopting the above-mentioned further technical solution are as follows: by setting up a handrail, it is convenient for farmers to operate the machine; by connecting the handbrake to the pull rope and setting the handbrake on the handrail, it is convenient for farmers to control the raising and lowering of the garlic hoe blade.

[0023] The walking mechanism is located on the lower side of the support frame, the transmission mechanism is located on the upper side of the walking mechanism, and the walking mechanism is located between the engine and the garlic hoe blade.

[0024] The beneficial effects of adopting the above-mentioned further technical solution are as follows: the engine's power is transmitted sequentially from the front end of the support frame to the garlic-hoeing blade at the rear end of the support frame, enabling the garlic-hoeing blade to perform garlic-hoeing work; the lifting mechanism passes through the lifting channel, with one end connected to the limiting mechanism on the upper side of the lifting channel and the other end connected to the mounting seat on the lower side of the lifting channel, thereby facilitating the lifting mechanism to lift the mounting seat upward; the speed change mechanism is set on the upper side of the traveling mechanism and located between the engine and the garlic-hoeing blade, which can improve the stability of the garlic-hoeing machine during operation.

[0025] Furthermore, the mounting base is provided with a sliding tie rod mechanism, which includes a first connecting rod and a second connecting rod, the first connecting rod being connected to the mounting base;

[0026] The second connecting rod is provided with a sliding groove, and the first connecting rod is rotatably connected to the second connecting rod;

[0027] A row divider is rotatably connected to the support frame, and a sliding pin that cooperates with a sliding groove is provided on the row divider.

A sliding groove two is provided inside the connecting rod three, and a sliding pin two that cooperates with the sliding groove two is provided on the walking mechanism.

[0029] More preferably, the row divider is located at the front end of the support frame, and the sliding tie rod mechanism is located on the left and / or right side of the support frame.

[0030] The beneficial effects of adopting the above-mentioned further technical solution are as follows: When the mounting base rotates on the support frame, connecting rod one rotates upward, thereby driving connecting rod two to move, causing sliding pin one of the raffia divider to slide in groove one, thereby driving the raffia divider to rotate on the support frame, preventing the raffia divider from extending into the soil when turning, and enabling easy turning; by rotating the mounting base upward on the support frame, connecting rod three moves, causing sliding pin two of the traveling mechanism to slide in groove two, thereby driving the traveling mechanism to lift upward, preventing the traveling mechanism from tilting forward after lifting the handrail when turning, avoiding difficulty in lifting off the ground, and making turning more convenient; by setting the sliding tie rod mechanism on the left and / or right side of the support frame and connecting it to the raffia divider at the front end of the support frame, the sliding tie rod mechanism can easily drive the raffia divider upward, preventing the raffia divider from contacting the ground when turning.

[0031] Furthermore, the walking mechanism includes a transmission gear, a drive wheel, a driven wheel, a track, a support plate one, and a support plate two. The track is disposed on the outside of the transmission gear, the drive wheel, and the driven wheel. The transmission gear meshes with the track, and the track has an overall triangular structure.

[0032] The transmission gear is provided with a transmission shaft that is connected to the speed change mechanism. The first support plate is connected to the support frame. The first support plate and the second support plate are sleeved on the outside of the transmission shaft. The driving wheel and the driven wheel are connected to the second support plate.

[0033] The second sliding pin is located at the end of the second support plate near the passive wheel.

[0034] The beneficial effects of adopting the above-mentioned further technical solution are as follows: the transmission mechanism drives the transmission gear to rotate, which in turn drives the track to rotate. The track, by wrapping around the outside of the drive wheel and the driven wheel, can move stably under the support of the drive wheel and the driven wheel. By using support plate one and support plate two to be sleeved on the outside of the transmission shaft, the walking mechanism is rotatably connected to the support frame. This allows the walking mechanism to float up and down to adapt to changes in terrain when encountering uneven terrain, thus keeping the plow depth constant. By using sliding pin two to be set at the end of support plate two near the driven wheel, when turning, one end of the driven wheel of the walking mechanism can be raised, and one end of the drive wheel can contact the ground, preventing the walking mechanism from swaying. When raising the handle, the inclined walking mechanism can reduce the resistance of contact with the ground, making turning more convenient.

[0035] Furthermore, the support frame is provided with a traveling wheel at the end away from the engine, and the traveling wheel is provided with a spacing adjustment device;

[0036] The row spacing adjustment device includes an adjustment rod and a limiting member. The adjustment rod is slidably engaged with the walking wheel and connected to the support frame. The limiting member is engaged with the adjustment rod and locked in place.

[0037] The limiting component includes a retaining plate, which is connected to the traveling wheel. The retaining plate is slidably mounted on the adjusting rod. The retaining plate is provided with an adjusting hole, an adjusting bolt is provided in the adjusting hole, and an adjusting nut is provided on the adjusting bolt.

[0038] The beneficial effects of adopting the above-mentioned further technical solution are as follows: by setting the walking wheels, the balance of the garlic hoeing machine can be improved; by tightening the adjusting bolt, the clamping plate and the adjusting rod are locked; when the adjusting bolt is loosened, the clamping plate slides on the adjusting rod, thereby driving the walking wheels to slide on the adjusting rod, realizing the adjustment of the distance between the walking wheels, which makes it convenient for the garlic hoeing machine to be used on garlic with different row spacings.

[0039] Furthermore, it also includes a garlic-hoeing transmission device, which includes an eccentric wheel and a movable rod. The eccentric wheel and the movable rod are connected. The eccentric wheel is connected to a transmission mechanism, and the movable rod is connected to the garlic-hoeing blade.

[0055] This embodiment provides Example 1.

[0056] Please see Figure 1-11A garlic hoeing machine with a lifting mechanism includes a support frame 1, on which an engine 12 and a transmission mechanism 13 are mounted. The engine 12 is driven to the transmission mechanism 13, which is driven to a walking mechanism 2 and a garlic hoeing blade 15. The support frame 1 is rotatably connected to a mounting base 3, and the garlic hoeing blade 15 is rotatably connected to the mounting base 3. The mounting base 3 is rotatably connected to a lifting mechanism 4. The support frame 1 is provided with a limiting mechanism 5 that is detachably connected to the lifting mechanism 4. A lifting channel 14 is provided at the end of the support frame 1 away from the engine 12. The garlic hoe 15 is connected to a lifting mechanism 4. When a turn is needed, the lifting mechanism 4 is raised, causing it to rotate on the support frame 1. This moves the mounting base 3 upward, which in turn moves the garlic hoe 15 upward within the lifting channel 14. After a certain distance from the ground, a limiting mechanism 5 engages with the lifting mechanism 4 to limit its movement, allowing the garlic hoe 15 to turn at a certain height above the ground, preventing it from contacting the ground and enabling easy turning. When the garlic hoe 15 is to work again, the limiting mechanism 5 disengages from the lifting mechanism 4, causing the lifting mechanism 4 to move downward. This moves the mounting frame and the garlic hoe 15 downward within the lifting channel 14, bringing it into contact with the ground for garlic hoeing.

[0057] The mounting base 3 includes a base 31, on which a tool mounting shaft 32, a support shaft 33, and a connecting shaft 34 are provided.

The fixing members 35 are connected to the tool mounting shaft 32, the connecting shaft 34, and the support shaft 33. The lifting mechanism 4 is connected to the base 31. More preferably, the base 31 and the fixing members 35 are plate-shaped. When the lifting mechanism 4 pulls the mounting base 3 to move, the connecting shaft 34 rotates along the support frame 1, thereby driving the garlic hoe 15 to move up and down. The garlic hoe 15 is rotatably mounted on the tool mounting shaft 32. The fixing member 35 can limit the two sides of the tool mounting shaft 32 to prevent the garlic hoe 15 from falling off the tool mounting shaft 32. The lifting mechanism 4 is connected to the base 31, and the fixing member 35 is connected to the tool mounting shaft 32, the connecting shaft 34 and the support shaft 33, thereby ensuring the stability of the lifting when the garlic hoe 15 is lifted. The plate shape of the base 31 and the fixing member 35 makes the mounting base 3 lighter, which is conducive to the lifting of the lifting mechanism 4.

[0058] The lifting mechanism 4 includes a steering wrench 41 and a lifting rod 42, which are rotatably connected to the steering wrench 41 and the mounting base 3. The steering wrench 41 is provided with several retaining holes 43, and the limiting mechanism 5 engages with the retaining holes 43 to engage them. When the farmer rotates the steering wrench 41, it causes the lifting rod 42 to move, which in turn causes the garlic hoe 15 in the mounting base 3 to move vertically within the lifting channel 14. The limiting mechanism 5 engages with the retaining holes 43 on the steering wrench 41 to engage it. When the garlic hoe 15 moves to a suitable position, it is limited, allowing the garlic hoe 15 to turn while maintaining a certain distance from the ground.

[0059] The limiting mechanism 5 includes a first limiting plate 51, a second limiting plate 52, a limiting cylinder 53, and a telescopic device. The first limiting plate 51 and the second limiting plate 52 are respectively disposed on both sides of the steering wrench 41.

The rope 57, the limiting cylinder 53 includes a bottom wall 531 and a side wall 532, the bottom wall 531 is located on the side away from the limiting plate 1 51, the rope 57 passes through the bottom wall 531 and is connected to the clamping post 55, the clamping post 55 is slidably disposed in the limiting cylinder 53, the elastic element 56 is disposed between the clamping post 55 and the bottom wall 531, the clamping post 55 is engaged with the clamping hole 43 for clamping; preferably, the length of the clamping post 55 is greater than the distance between the limiting hole 1 511 and the limiting hole 2 521; more preferably, the support frame 1 is provided with a handrail 9, the handrail 9 is located on the side away from the engine 12, the handrail 9 is provided with a handbrake 91, the handbrake 91 is connected to the rope 57. The steering wrench 41 rotates on the pivot 54 between the first limiting plate 51 and the second limiting plate 52. The clamping post 55 of the telescopic device is tightly fitted with the steering wrench 41. When the clamping hole 43 is between the first limiting hole 511 and the second limiting hole 521, under the elastic action of the elastic element 56, the clamping post 55 moves from inside the limiting cylinder 53 into the clamping hole 43, thereby clamping the steering wrench 41 and raising the garlic hoe 15 to the appropriate position. When the length of the clamping post 55 is... When the distance between the first limiting hole 511 and the second limiting hole 521 is greater than the distance between the limiting hole 511 and the second limiting hole 521, the clamping post 55 can pass through the first limiting hole 511, the second limiting hole 521 and the clamping hole 43, thereby clamping the steering wrench 41, so that the clamping post 55 and the steering wrench 41 are in stable clamping. By setting the handle 9, it is convenient for farmers to operate the machine. The handbrake 91 is connected to the pull rope 57 and is set on the handle 9, so that farmers can easily control the raising and lowering of the garlic hoe 15.

[0060] The engine 12 is located on the upper side of the front end of the support frame 1. The transmission mechanism 13 is located between the engine 12 and the garlic hoe 15. The lifting channel 14 is located at the rear end of the support frame 1. The mounting base 3 is located on the lower side of the lifting channel 14. The limiting mechanism 5 is located on the upper side of the support frame 1 and at the end of the lifting channel 14 away from the engine 12. One end of the lifting mechanism 4 is located on the upper side of the lifting channel 14 and is detachably connected to the limiting mechanism 5. The other end of the lifting mechanism 4 is located on the lower side of the lifting channel 14 and is rotatably connected to the mounting base 3. The walking mechanism 2 is located on the lower side of the support frame 1. The transmission mechanism 13 is located on the upper side of the walking mechanism 2. The walking mechanism 2 is located between the engine 12 and the garlic hoe 15. The power of the engine 12 is transmitted sequentially from the front end of the support frame 1 to the garlic hoeing blade 15 at the rear end of the support frame 1, enabling the garlic hoeing blade 15 to perform garlic hoeing work. The lifting mechanism 4 passes through the lifting channel 14, with one end connected to the limiting mechanism 5 on the upper side of the lifting channel 14 and the other end connected to the mounting seat 3 on the lower side of the lifting channel 14, so that the lifting mechanism 4 can easily lift the mounting seat 3 to move upward. The speed change mechanism 13 is set on the upper side of the walking mechanism 2 and is located between the engine 12 and the garlic hoeing blade 15, which can improve the stability of the garlic hoeing machine during operation.

[0061] The mounting base 3 is provided with a sliding rod mechanism 6, which includes a first connecting rod 61, a second connecting rod 62, and a third connecting rod 63. The first connecting rod 61 is connected to the mounting base 3. The second connecting rod 62 is provided with a first sliding groove 621, and the first connecting rod 61 is rotatably connected to the second connecting rod 62. A row divider 7 is rotatably connected to the support frame 1, and the row divider 7 is provided with a first sliding pin 71 that cooperates with the first sliding groove 621. Preferably, the sliding rod mechanism 6 further includes a third connecting rod 63, which is rotatably connected to the mounting base 3. The third connecting rod 63 is provided with a second sliding groove 631, and the walking mechanism 2 is provided with a second sliding pin 261 that cooperates with the second sliding groove 631.

[0062] Preferably, the row divider 7 is located at the front end of the support frame 1, and the sliding tie rod mechanism 6 is located on the left and / or right side of the support frame 1. When the mounting base 3 rotates on the support frame 1, connecting rod 61 rotates upward, thereby driving connecting rod 62 to move. This causes sliding pin 71 of the row divider 7 to slide within groove 621, thus driving the row divider 7 to rotate on the support frame 1. This prevents the row divider 7 from extending into the soil when turning, allowing for easy turning. The upward rotation of the mounting base 3 on the support frame 1 also drives connecting rod 63 to move, causing sliding pin 261 of the traveling mechanism 2 to slide within groove 631. This lifts the traveling mechanism 2 upward, preventing it from tilting forward after lifting the handrail 9 when turning, avoiding difficulty in lifting off the ground and making turning easier. The sliding tie rod mechanism 6, located on the left and / or right side of the support frame 1 and connected to the row divider 7 at the front end of the support frame 1, allows the sliding tie rod mechanism 6 to easily lift the row divider 7 upward, preventing it from contacting the ground when turning.

[0063] The walking mechanism 2 includes a transmission gear 21, a drive wheel 22, a driven wheel 23, a track 24, a first support plate 25, and a second support plate 26. The track 24 is located outside the transmission gear 21, the drive wheel 22, and the driven wheel 23. The transmission gear 21 meshes with the track 24, and the track 24 has an overall triangular structure. The transmission gear 21 is provided with a transmission shaft 211 that is connected to the transmission mechanism 13. The first support plate 25 is connected to the support frame 1. The first support plate 25 and the second support plate 26 are sleeved on the outside of the transmission shaft 211. The drive wheel 22 and the driven wheel 23 are connected to the second support plate 26. The second sliding pin 261 is located at the end of the second support plate 26 near the driven wheel 23. The transmission mechanism 13 drives the transmission gear 21 to rotate, which in turn drives the track 24 to rotate. The track 24, which surrounds the drive wheel 22 and the driven wheel 23, can move stably under the support of the drive wheel 22 and the driven wheel 23. The support plate 1 25 and the support plate 26 are sleeved on the outside of the transmission shaft 211, thereby rotatably connecting the walking mechanism 2 to the support frame 1. This allows the walking mechanism 2 to float up and down to adapt to changes in terrain when encountering uneven terrain, thus keeping the plow depth constant. The sliding pin 2 71 is set at the end of the support plate 2 26 near the driven wheel 23. When turning, it can raise one end of the driven wheel 23 of the walking mechanism 2, and the one end of the drive wheel 22 contacts the ground, preventing the walking mechanism 2 from swaying. When the handle 9 is raised, the inclined walking mechanism 2 can reduce the resistance of contact with the ground, making turning easier.

[0064] The support frame 1 is provided with a traveling wheel 16 at the end away from the engine 12. The traveling wheel 16 is provided with a spacing adjustment device.
