Technical Field

[0001] This invention belongs to the technical field of Chinese medicinal herb harvesting equipment, specifically a self-propelled chassis for a Chinese medicinal herb harvester. Background Technology

[0002] At present, with the diversification of agriculture, many regions are gradually shifting from field crops to cash crops. The planting area of ​​deep-rooted cash crops is increasing, but the harvesting problem is becoming more and more prominent. As a result, a large number of Chinese medicinal herb harvesting equipment have been developed.

[0003] Existing medicinal herb harvesting devices typically require manual pushing to move the entire machine forward to harvest the herbs. However, they usually cannot move automatically during the harvesting process, resulting in a low level of automation. The mobile chassis of existing medicinal herb harvesting devices usually requires a power-assisted vehicle to control its movement, making the entire device large and increasing manufacturing costs. Turning the mobile chassis of existing medicinal herb harvesting devices is also cumbersome, reducing the harvesting efficiency of medicinal herbs.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This invention controls the extension and retraction of the track telescopic rod through a track telescopic controller, which allows the track auxiliary gear to move left and right, thereby changing the distance between the track gear and the track auxiliary gear. This allows the track gear and the track auxiliary gear to be adapted to tracks of different lengths, thus increasing the number of track models and the range of equipment compatibility.

[0017] This invention controls the extension and retraction of the roller telescopic rod through a roller telescopic controller, which makes the roller height variable. This allows the roller and roller telescopic rod to suspend the track when the entire equipment needs to turn, so that the track will not damage the underground medicinal materials due to gravity when the entire equipment turns, thereby increasing the yield of harvested medicinal materials.

[0018] This invention controls the rotation of the roller rotation gear by a roller rotation motor, which in turn rotates the roller rotation secondary gear. This gear engages with the roller rotation bearing, thereby driving the roller rotation shaft to rotate. Ultimately, the roller rotates around the roller rotation shaft, creating a corresponding angle between the roller and the track. This allows the roller to rotate along the desired track, and consequently, the entire device to rotate at the required angle, thus achieving automated steering.

[0019] The mobile motor of this invention drives the mobile gear to rotate the mobile shaft, which in turn drives the track gear to rotate, thereby causing the track to rotate and the entire device to start moving. This allows the digging blade to complete the digging work, while the conveyor belt transports the Chinese medicinal materials to the collection box, making the device more integrated and reducing its size.

[0020] The lifting motor of this invention controls the rotation of the lifting gear to drive the right gear to rotate, while simultaneously causing the left gear to rotate in the opposite direction. This causes the right screw to rotate, which in turn drives the left screw to rotate in the opposite direction. Consequently, the right and left bearings of the lifting box move up and down, causing the lifting box to move up and down. This, in turn, causes the tracks to move up and down, which in turn causes the digging blade to move up and down. This allows the digging blade to change the depth at which it digs medicinal herbs, thus adapting to different depths of medicinal herb planting sites and ensuring the accuracy of harvesting medicinal herbs.

The inner ring of the right bearing 311 of the lifting box is fixedly connected to the right screw 301, and its outer ring is fixedly connected to the upper surface of the lifting box 3. The right bearing 311 of the lifting box is made of hard steel. The left gear 322 is internally connected to a left screw 302 via a threaded engagement.

The inner ring of the left bearing 321 is fixedly connected to the left screw 302, and its outer ring is fixedly connected to the upper surface of the lifting box 3. The right bearing 311 and the left bearing 321 of the lifting box cooperate with each other to allow the lifting box 3 to move up and down, thereby allowing the track 4 to move up and down. A moving motor 303 is installed inside the lifting box 3.

The track auxiliary gear 402 is rotatably connected to the left side of each track telescopic rod 403 by a fixing plate.The track auxiliary gear 402 and the track gear 401 cooperate to fix the track 4.

[0039] Before using this invention, the controller 102 controls the track telescopic controller 406 to start working, thereby causing the track telescopic rod 403 to retract, which in turn causes the track secondary gear 402 to move to the right. At this time, the operator installs the track 4 on the outside of the track gear 401. Then, the controller 102 controls the track telescopic controller 406 to work in the opposite direction, thereby causing the track telescopic rod 403 to extend, which in turn causes the track secondary gear 402 to move to the left, thus tautning the track 4. At this time, the controller 102 controls the moving motor 303 to start working, which in turn causes the moving gear 304 to start working, which in turn drives the moving secondary gear 305 to rotate, which in turn causes the moving shaft 306 to rotate, which in turn drives the track gear 401 to rotate, so that the track 4 rotates around the track gear 401, thereby making the entire device rotate. When the entire device moves to the desired position, the camera 9 starts working. If the camera 9 detects that there are no Chinese medicinal herbs above the conveyor belt 8, the controller 102 controls the lifting motor 505 to start working, thereby causing the lifting gear 504 to rotate, which in turn drives the right gear 312 to rotate clockwise and the left gear 322 to rotate counterclockwise, thereby driving the right screw 301 to rotate counterclockwise and the left screw 302 to rotate clockwise. This causes the right screw 301 and the left screw 302 to move upward, thereby causing the right bearing 311 and the left bearing 321 of the lifting box to move upward, thus causing the lifting box 3 to move upward, thereby achieving the purpose of lowering the conveyor belt 8, thereby causing the digging cutter 801 to descend, thereby changing the digging depth and starting the digging work.

[0040] Example 3, based on Example 1, is... Figure 8-9Each of the roller telescopic rods 2 is telescopic and is made of hard steel. A roller telescopic controller 203 is fixed to the outside of each roller telescopic rod 2. The roller telescopic controller 203 controls the extension and retraction of the roller telescopic rod 2, thereby driving the roller 202 to move up and down. Each roller rotating box 201 contains a roller rotating motor 214. The interior of the roller rotating box 201 is hollowed out, and the roller rotating motor 214 is fixed to the upper surface inside the roller rotating box 201. The roller rotation motor 214 controls the rotation of the roller rotation gear 213. The roller rotation motor 214 has the roller rotation gear 213 rotatably connected to its bottom. The roller rotation gear 213 drives the roller rotation auxiliary gear 212, which meshes with it, to rotate. The roller rotation gear 213 is meshed with the roller rotation auxiliary gear 212, which drives the roller rotation shaft 207 to rotate. The roller rotation shaft 207 is fixed to the bottom of the roller rotation auxiliary gear 212. The roller rotating shaft 207 can drive the roller fixing plate 208 to rotate.

The roller moving gear 204 is meshed with the roller moving auxiliary gear 205. The roller moving auxiliary gear 205 drives the roller 202 to rotate. The roller moving auxiliary gear 205 is rotatably connected to the roller 202 on the right rear side via a rotating shaft.

[0041] When using this invention, after the entire device has harvested a row of Chinese medicinal herbs, the controller 102 controls multiple roller telescopic controllers 203 to start working, thereby extending multiple roller telescopic rods 2, causing the rollers 202 to move downwards, thus supporting the entire device. When the track 4 leaves the ground due to the action of the roller telescopic rods 2, the controller 102 controls multiple roller rotation motors 214 to start working, causing each roller rotation gear 213 to start rotating, which in turn drives the roller rotation secondary gear 212 to start rotating, thereby causing the roller rotation shaft 207 to rotate, which in turn causes the roller fixing plate 208 to rotate, thus causing the roller 202 to rotate. After rotating a certain angle, the controller 102... 2. The controller stops the multiple roller rotation motors 214. At this time, the controller 102 controls the roller moving motor 206 on the outer surface of the roller fixing plate 208 at the right rear to start working, thereby causing the roller moving gear 204 to start working, thereby causing the roller moving secondary gear 205 to start working, thereby causing the roller 202 at the right rear end to start rotating, thereby causing the entire device to start rotating. After the entire device has rotated a certain angle, the controller 102 controls the moving motor 303 to start working, thereby causing the entire device to move again. After multiple operations, the entire device is parallel to the unexcavated Chinese medicinal herb plot, and the camera 9 of the entire device is positioned on the side closer to the unexcavated Chinese medicinal herb plot. At this time, the controller 102 controls the entire device to start harvesting again.

[0042] Example 4, based on Example 1, by Figure 5 As shown, a transmission motor 802 is fixed to the rear of the fixed plate 7. The transmission motor 802 can drive the transmission shaft 803 to rotate. The transmission motor 802 is rotatably connected to the transmission shaft 803. The transmission shaft 803 can drive the transmission belt 8 to rotate, thereby completing the purpose of transporting Chinese medicinal materials. The front and rear ends of the transmission shaft 803 are rotatably connected to the transmission bearings 804. The inner ring of the transmission bearing 804 is fixedly connected to the transmission shaft 803, and the outer ring of the transmission bearing 804 is fixedly connected to the fixed plate 7. Each fixed plate 7 has a transmission auxiliary bearing 806 fixed at its bottom. The outer ring of the transmission auxiliary bearing 806 is fixedly connected to the fixed plate 7, and the inner ring of the transmission auxiliary bearing 806 is rotatably connected to the transmission auxiliary shaft 807. The transmission auxiliary shaft 807 is used to fix the transmission belt 8.

[0043] When the track 4 rises to the desired position, the entire device begins to move due to the action of the track 4, causing the digging blade 801 to move forward, thus digging the ground. At this time, because there is a gap between every two digging blades 801, the medicinal herbs slide from above the digging blades 801 onto the conveyor belt 8. The controller 102 then controls the conveyor motor 802 to start working, causing the conveyor shaft 803 to rotate, which in turn drives the conveyor belt 8 to rotate, thereby driving the secondary conveyor shaft 807 to rotate, allowing the medicinal herbs to slide onto the conveyor belt. As the upper surface of conveyor belt 8 moves upward, the soil falls from the upper surface of conveyor belt 8 to the ground. When the medicinal herbs rise along conveyor belt 8 to the top of conveyor belt 8, they fall into the collection box 6 due to inertia. Due to the internal structure of the collection box 6, they roll to the discharge port 601. At this time, the baffle 602 prevents the medicinal herbs from falling out. When the collection box 6 is full, the controller 102 controls the entire device to stop moving. At this time, the worker pulls out the baffle 602, allowing the medicinal herbs to roll out from the discharge port 601, thus completing the collection work.

[0044] The workflow of this invention is as follows: Before using this invention, the controller 102 controls the track telescopic controller 406 to start working, thereby causing the track telescopic rod 403 to retract, which in turn causes the track secondary gear 402 to move to the right. At this time, the operator installs the track 4 on the outside of the track gear 401. Then, the controller 102 controls the track telescopic controller 406 to work in the opposite direction, thereby causing the track telescopic rod 403 to extend, which in turn causes the track secondary gear 402 to move to the left, thereby tautning the track 4. At this time, the controller 102 controls the moving motor 303 to start working, which in turn causes the moving gear 304 to start working, which in turn drives the moving secondary gear 305 to rotate. This causes the moving shaft 306 to rotate, which in turn drives the track gear 401 to rotate, causing the track 4 to rotate around the track gear 401, thus initiating the movement of the entire device. When the entire device moves to the desired position, the camera 9 starts working. If the camera 9 detects that there are no Chinese medicinal herbs above the conveyor belt 8, the controller 102 controls the lifting motor 505 to start working, causing the lifting gear 504 to rotate, which in turn drives the right gear 312 to rotate clockwise, while simultaneously causing the left gear 322 to rotate counterclockwise, thereby driving the right screw 301 to rotate counterclockwise, while simultaneously causing the left screw 302 to rotate clockwise, thus causing the right screw 301 and the left screw 302 to rotate clockwise, thus causing the right screw 301 and the left screw 302 to rotate counterclockwise. The left screw 302 moves upward, causing the right bearing 311 and the left bearing 321 of the lifting box to move upward, thus moving the lifting box 3 upward and lowering the conveyor belt 8. This causes the digging blade 801 to descend, changing the digging depth and initiating digging work. At this time, the track 4 causes the entire equipment to move, moving the digging blade 801 forward to dig into the ground. Because there is a gap between every two digging blades 801, the medicinal herbs slide from above the digging blades 801 onto the conveyor belt 8. At this point, the controller 102 controls the conveyor motor 802 to start working, thereby... The conveyor shaft 803 begins to rotate, which in turn drives the conveyor belt 8 to rotate, thereby driving the secondary conveyor shaft 807 to rotate. This causes the medicinal herbs to move upwards on the upper surface of the conveyor belt 8. At this time, soil falls from the upper surface of the conveyor belt 8 to the ground. When the medicinal herbs rise along the conveyor belt 8 to the top, they fall into the collection box 6 due to inertia. Due to the internal structure of the collection box 6, they roll to the discharge port 601. At this time, the baffle 602 prevents the medicinal herbs from falling out. After the entire device has harvested a row of medicinal herbs, the controller 102 controls multiple roller telescopic controllers 203 to start working, thereby causing multiple roller telescopic rods 2 to extend.This causes the roller 202 to move downwards, thus supporting the entire device. When the track 4 leaves the ground due to the action of the roller telescopic rod 2, the controller 102 controls multiple roller rotation motors 214 to start working, causing each roller rotation gear 213 to start rotating, which in turn drives the roller rotation secondary gear 212 to start rotating, thereby causing the roller rotation shaft 207 to rotate, which in turn causes the roller fixing plate 208 to rotate, thus causing the roller 202 to rotate. After rotating a certain angle, the controller 102 controls multiple roller rotation motors 214 to stop working. At this time, the controller 102 controls the roller moving motor 206 on the outer surface of the roller fixing plate 208 on the right rear to start working, thereby causing the roller 202 to rotate. The wheel-moving gear 204 starts working, which in turn activates the roller-moving secondary gear 205, causing the right rear roller 202 to rotate. This causes the entire device to rotate. After the device has rotated a certain angle, the controller 102 activates the moving motor 303, causing the device to move again. After several operations, the device becomes parallel to the unexcavated medicinal herb plot, with the camera 9 positioned closer to the unexcavated plot. At this point, the controller 102 controls the device to begin harvesting again. When the collection box 6 is full, the controller 102 stops the device. The worker then removes the baffle 602, allowing the medicinal herbs to roll out from the discharge port 601, completing the collection process.
