Description

Technical Field

[0001] The present invention relates to the technical field of medicinal material harvesting equipment, and particularly relates to a rhizome Chinese medicinal material harvester for rolling and removing soil. Background Art

[0002] Rhizome medicinal materials mainly include astragalus membranaceus, licorice, bupleurum chinense, angelica sinensis, codonopsis pilosula, isatis indigotica, rheum officinale, ephedra sinica, scutellaria baicalensis, pinellia ternata, etc. The traditional harvesting method for rhizome medicinal materials is to dig them manually, which has a high labor intensity and a large workload. With the continuous development of harvesting equipment, more and more Chinese medicinal material growers adopt mechanical harvesting methods.

[0003] At present, there are many models and types of Chinese medicinal material harvesters, but their basic principles are similar. They all adopt a digging harvesting method, where the soil is dug open and then the medicinal materials are subjected to soil removal and collection operations. This harvesting method has the advantages of high efficiency and strong applicability.

[0004] However, the digging harvesting method for medicinal materials also has relatively serious disadvantages. After the soil and Chinese medicinal materials are dug up together by the soil digging mechanism of the machine, a large amount of soil and dust will be generated, and the mixture of soil and Chinese medicinal materials needs to be transported to the screening mechanism of the machine for soil removal, separation, and collection operations. This results in a large amount of soil adhering to the mechanical components of the harvester, which is likely to increase mechanical wear and mechanical failures and increase the maintenance difficulty. Summary of the Invention

[0005] In view of the above problems, the present invention provides a rhizome Chinese medicinal material harvester for rolling and removing soil. Two clamping plates clamp the Chinese medicinal materials. As the rotating ring continues to rotate, the two clamping plates pull out the Chinese medicinal materials from the soil to achieve the picking operation. Different from the traditional digging method, it effectively reduces the generated dust and soil. The shaking mechanism shakes the roots of the Chinese medicinal materials outside the machine, and the soil shakes directly onto the land. There is no need to transport the mixture of soil and Chinese medicinal materials to the screening mechanism, reducing the large amount of soil adhering to the mechanical components. The mechanical components do not come into full contact with the soil, thereby reducing mechanical wear and mechanical failures.

[0006] The technical solution adopted to solve the above technical problems is as follows: A root and rhizome Chinese medicinal material harvester for rolling and removing soil includes a bracket, a plurality of picking mechanisms, a cutting edge, a plurality of rotating mechanisms, and a shaking mechanism.

[0007] Further, the shaking frame includes a frame body and a plurality of arc-shaped rods. The frame body is slidably connected to the cutting edge, a plurality of arc-shaped rods are connected to the lower side of the frame body, the radian of the arc-shaped rods matches that of the rotating ring, and every two arc-shaped rods form a group, and the position of each group of arc-shaped rods matches that of the sliding plates of each picking mechanism.

[0008] Further, the rotating mechanism includes a gear, a first motor, and a toothed ring. The gear is rotatably connected to the support ring, the first motor is connected to the support ring, the output shaft of the first motor is fixedly connected to the gear, the toothed ring is coaxially fixedly connected to one of the rotating rings, and the toothed ring meshes with the gear.

[0009] Further, the shaking mechanism includes a second motor, a swinging block, and a sliding groove. The second motor is connected to the cutting edge; the swinging block is eccentrically connected to the output shaft of the second motor; the sliding groove is formed on the frame body, and the swinging block moves in the sliding groove.

[0010] Further, sliders are slidably connected to both sides below the feeding plate member. The sliders slide along the horizontal direction and perpendicular to the axis of the rotating ring. One side of the slider is connected with a second spring for its reset. A clamping block is slidably connected to the slider. The clamping block slides along the axial direction of the rotating ring. A third spring for its reset is connected to the clamping block. The clamping blocks on both sides are symmetrically arranged. Second entry grooves are formed on the adjacent sides of the clamping blocks on both sides. A displacement sensor is connected to one of the clamping blocks. The position of the clamping block matches that of the sliding plates of each picking mechanism. Spreading blocks are connected to both sides below the feeding plate member. The end of the spreading block is provided with an inclined surface, one side of the clamping block is provided with an inclined surface, and the inclined surface of the spreading block cooperates with the inclined surface of the clamping block.

[0011] Further, a plurality of auxiliary wheels are evenly connected to the support ring along the circumferential direction.

[0012] Furthermore, a material receiving platform is slidably connected to one side of the bracket, a fourth spring is connected to the material receiving platform, and the material receiving platform is arranged close to the arc rod.

[0013] Furthermore, a material receiving rack is slidably connected to the bracket, the material receiving rack is located on the inner side of the rotating circle, an arc surface is arranged on the upper side of the material receiving rack, and a fifth spring acting on the material receiving rack is connected to the material receiving rack.

[0014] Furthermore, a connecting piece is connected to one side of the bracket.

[0015] The beneficial effects of the present invention are:

[0016] (1) The present invention can perform a picking operation on rhizomes of Chinese medicinal materials by providing a picking mechanism. When the machine moves, the Chinese medicinal materials enter the middle position of the feeding plate, and the rotating mechanism drives the rotating circle to rotate, thereby driving multiple connecting rods to rotate synchronously. The connecting rods rotate and drive the clamps on both sides to rotate. When the connecting rods rotate to the feeding plate position, the rhizomes of the Chinese medicinal materials enter between the two clamps, and the two clamps clamp the Chinese medicinal materials. As the rotating circle continues to rotate, the two clamps pull the Chinese medicinal materials out of the soil to achieve a picking operation. Different from the traditional digging method, the dust and soil generated are effectively reduced. When the rotating circle continues to rotate, the Chinese medicinal materials contact the cutting blade, and the cutting blade cuts off and separates the rhizomes and leaves of the Chinese medicinal materials. Before cutting, the shaking mechanism shakes the roots of the Chinese medicinal materials on the outside of the machine, and shakes the soil directly onto the ground. There is no need to transport the mixture of soil and Chinese medicinal materials to the screening mechanism, which reduces the large amount of soil adhering to the mechanical parts. The mechanical parts will not fully contact the soil, thereby reducing mechanical wear and mechanical failure.

[0017] (2) The present invention cooperates with the picking mechanism by setting sliders, clamps, displacement sensors and other components. When the machine moves, the rotating circle does not rotate directly. After the Chinese medicinal materials first enter the middle position of the feeding plate, the Chinese medicinal materials contact the two clamps and enter the second entry slot. At the same time, the two clamps and two sliders are pushed to move. The movement of the clamps drives the displacement sensor to move. When the clamps move to contact the opening blocks, the displacement sensor sends a signal. At this time, the rotating mechanism is operated to drive the rotating circle to rotate a certain angle to perform the Chinese medicinal materials picking operation. The movement of the clamps and the displacement sensor acts as a trigger. The rotating circle is rotated only when the Chinese medicinal materials enter the position to be picked, thereby reducing unnecessary work.

[0018] (3) The present invention provides auxiliary wheels to enable the rotating ring to rotate on the supporting ring. This rolling friction rotation mode is not easy to get stuck, and dirt and dust can be quickly discharged from the rotating connection, further reducing the probability of mechanical failure and reducing the difficulty of maintenance.

Embodiment

[0030] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] Such as Figure 1 、 Figure 2 、 Figure 3 、Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown in Figure 4 , Figure 5 , Figure 6 , and Figure 7 , a root and rhizome Chinese medicinal material harvesting machine for rolling and removing soil provided in this embodiment includes a bracket 1, a plurality of picking mechanisms 2, a cutting edge 3, a plurality of rotating mechanisms 5, and a shaking mechanism 6. A plurality of picking mechanisms 2 are arranged side by side on the bracket 1. The picking mechanism 2 includes: a feeding plate member 21 connected to the bracket 1. Support rings 22 are connected to both sides of the feeding plate member 21. A rotating ring 23 is rotatably connected to the support rings 22; a plurality of connecting rods 24 are equidistantly connected along the circumferential direction between the two rotating rings 23. Clamping plates 25 are slidably connected to both sides of the rotating rings 23. The clamping plates 25 slide along the axial direction of the rotating ring 23. The clamping plates 25 on both sides cooperate with each other one by one. First entry grooves 26 are formed on the adjacent sides of the clamping plates 25 on both sides; a first spring 27 is connected to one side of the clamping plate 25; the cutting edge 3 is connected to the bracket 1. A shaking frame 4 is slidably connected to the cutting edge 3. The shaking frame 4 slides along the axial direction of the rotating ring 23. A plurality of rotating mechanisms 5 are respectively connected to the plurality of support rings 22. The rotating mechanism 5 is used to drive the corresponding rotating ring 23 to rotate; the shaking mechanism 6 is connected to the cutting edge 3. The shaking mechanism 6 drives the shaking frame 4 to reciprocate.

[0032] In the present invention, by setting the picking mechanism 2, the picking operation of root and rhizome Chinese medicinal materials can be carried out. When the machine moves, the Chinese medicinal materials enter the middle position of the feeding plate member 21. The rotating mechanism 5 drives the rotating ring 23 to rotate, and then drives the plurality of connecting rods 24 to rotate synchronously. While the connecting rods 24 rotate, they drive the clamping plates 25 on both sides to rotate. When rotating to the position of the feeding plate member 21, the roots of the Chinese medicinal materials enter between the two clamping plates 25. The two clamping plates 25 clamp the Chinese medicinal materials. As the rotating ring 23 continues to rotate, the two clamping plates 25 pull out the Chinese medicinal materials from the soil, realizing the picking operation. Different from the traditional digging method, it effectively reduces the generated dust and soil. When the rotating ring 23 continues to rotate, the Chinese medicinal materials come into contact with the cutting edge 3. The cutting edge 3 cuts off and separates the roots and leaves of the Chinese medicinal materials. Before cutting, the shaking mechanism 6 shakes the roots of the Chinese medicinal materials outside the machine, and the soil shakes directly onto the land, without the need to transport the mixture of soil and Chinese medicinal materials to the screening mechanism, reducing a large amount of soil adhered to the mechanical components. The mechanical components do not come into full contact with the soil, thereby reducing mechanical wear and mechanical failures.

[0033] In the above embodiment, the number of connecting rods 24 in each picking mechanism 2 is four, that is, each picking mechanism 2 has four groups of clamping plates 25. The clamping plates 25 are slidably connected to the connecting rods 24 in the form of guide rods. The first spring 27 provides a force for the clamping plates 25, so that the two clamping plates 25 are joined.

[0034] Specifically, as Figure 2 , Figure 8As shown, the shaking frame 4 includes a frame body 41 and a plurality of arc-shaped rods 42. The frame body 41 is slidably connected to the cutting edge 3, and the plurality of arc-shaped rods 42 are connected to the lower side of the frame body 41. The radian of the arc-shaped rod 42 is matched with the rotating ring 23. Every two arc-shaped rods 42 form a group, and the position of each group of arc-shaped rods 42 is matched with the clamping plate 25 of each picking mechanism 2.

[0035] In the above embodiments, the frame body 41 is slidably connected to the cutting edge 3 in the way of a guide rod, or can also be slidably connected in the way of a slider 7. Each group of arc-shaped rods 42 corresponds to the clamping plate 25 on each picking mechanism 2. Each group of arc-shaped rods 42 shakes the Chinese herbal medicines to shake off the soil on the rhizomes of the Chinese herbal medicines. The arc-shaped rods 42 are arranged on the side of the rotating ring 23, and the soil on the Chinese herbal medicines is directly shaken off and falls on the land, without transporting a large amount of soil and Chinese herbal medicines to the machine for screening and soil removal, reducing the contact between the soil and the machine.

[0036] Specifically, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 shown, the rotating mechanism 5 includes a gear 51, a first motor 52 and a gear ring 53. The gear 51 is rotatably connected to the support ring 22, the first motor 52 is connected to the support ring 22, the output shaft of the first motor 52 is fixedly connected to the gear 51, and the gear ring 53 is coaxially and fixedly connected to one of the rotating rings 23. The gear ring 53 meshes with the gear 51.

[0037] In the above embodiments, the first motor 52 drives the gear 51 to rotate, the gear 51 drives the gear ring 53 to rotate, and then the rotating ring 23 rotates, realizing the rotation of the clamping plate 25.

[0038] Specifically, as Figure 1 、 Figure 2 、 Figure 8 shown, the shaking mechanism 6 includes a second motor 61, a swing block 62 and a sliding groove 63. The second motor 61 is connected to the cutting edge 3; the swing block 62 is eccentrically connected to the output shaft of the second motor 61; the sliding groove 63 is opened on the frame body 41, and the swing block 62 moves in the sliding groove 63.

[0039] In the above embodiments, when the clamping plate 25 picks up the Chinese herbal medicines and drives them to the position of the arc-shaped rods 42, the Chinese herbal medicines enter between each group of arc-shaped rods 42, that is, between two arc-shaped rods 42. The second motor 61 is operated to drive the swing block 62 to rotate. When the swing block 62 moves in the sliding groove 63, it drives the shaking frame 4 to make a reciprocating motion, and then drives the arc-shaped rods 42 to make a reciprocating motion, performing the shaking and soil removal operation on the Chinese herbal medicines.

[0040] Specifically, as Figure 4 、 Figure 5 、 Figure 9As shown in the figure, sliders 7 are slidably connected to both sides below the feeding plate member 21. The sliders 7 slide along the horizontal direction and perpendicular to the axis of the rotating ring 23. One side of the slider 7 is connected to a second spring 8 for its reset. A clamping block 9 is slidably connected to the slider 7. The clamping block 9 slides along the axial direction of the rotating ring 23. A third spring 10 for its reset is connected to the clamping block 9. The clamping blocks 9 on both sides are symmetrically arranged. Second entry slots 11 are provided on the adjacent sides of the clamping blocks 9 on both sides. A displacement sensor 12 is connected to one of the clamping blocks 9. The position of the clamping block 9 is matched with the clamping plates 25 of each picking mechanism 2. Support blocks 13 are connected to both sides below the feeding plate member 21. The end of the support block 13 is provided with an inclined surface. One side of the clamping block 9 is provided with an inclined surface. The inclined surface of the support block 13 is matched with the inclined surface of the clamping block 9.

[0041] In the above embodiment, the slider 7 is slidably connected to the feeding plate member 21 by means of a guide rod. The second spring 8 functions to reset the slider 7. When the machine moves, the Chinese herbal medicine rhizome first enters between the two clamping blocks 9 through the second entry slot 11. The Chinese herbal medicine pushes the two clamping blocks 9, and then pushes the slider 7 to move. At this time, both the second spring 8 and the third spring 10 are in a compressed state. When the Chinese herbal medicine pushes the clamping block 9 to move until it just comes into contact with the support block 13, the displacement sensor 12 sends a signal. At this time, the first motor 52 runs again, and the picking mechanism 2 starts the picking operation. The two clamping plates 25 move above the clamping block 9. The inclined surface of the clamping block 9 contacts the inclined surface of the support block 13, causing the two clamping blocks 9 to separate. At the same time, the Chinese herbal medicine enters the first entry slot 26. At this time, the first spring 27 provides a force for the two clamping plates 25, and the two clamping plates 25 pull out the Chinese herbal medicine from the soil.

[0042] Specifically, as Figure 4 、 Figure 5 、 Figure 6 shown, a plurality of auxiliary wheels 14 are evenly connected to the support ring 22 along the circumferential direction. The plurality of auxiliary wheels 14 are in contact with the inner side of the rotating ring 23. The rotating ring 23 is rotationally connected to the support ring 22 through the auxiliary wheels 14.

[0043] In the above embodiment, this rotational method of rolling friction is not easily jammed, and dirt and dust can be quickly discharged from the rotational connection, further reducing the probability of mechanical failures and the maintenance difficulty.

[0044] Specifically, as Figure 1 、 Figure 10 shown, a receiving table 15 is slidably connected to one side of the bracket 1. A fourth spring 16 is connected to the receiving table 15. The receiving table 15 is arranged close to the arc rod 42.

[0045] In the above embodiments, after the traditional Chinese medicine materials are shaken to remove soil, the traditional Chinese medicine materials rotate with the clamping plate 25, and the traditional Chinese medicine materials reach the upper side of the material receiving table 15. Since the material receiving table 15 is slidably connected to the bracket 1, the traditional Chinese medicine materials can push the material receiving table 15 to slide and then reach the upper side of the material receiving table 15. After the traditional Chinese medicine materials continue to rotate and contact the cutting edge 3, the cutting edge 3 cuts off the traditional Chinese medicine materials, and the rhizome part falls onto the material receiving table 15 for collection.

[0046] Specifically, as Figure 1 、 Figure 10 shown, a material receiving frame 17 is slidably connected to the bracket 1. The material receiving frame 17 is located inside the rotating circle 23, and the upper side of the material receiving frame 17 is provided with an arc surface. A fifth spring 18 acting on the material receiving frame 17 is connected to the material receiving frame 17.

[0047] In the above embodiments, for the traditional Chinese medicine materials cut off by the cutting edge 3, the rhizome part falls onto the material receiving table 15, while the leaf part falls onto the material receiving frame 17. Since the upper side of the material receiving frame 17 is provided with an arc surface, the leaves will slide down from the inclined surface and fall to the ground. When the machine is running, due to the action of the fifth spring 18, the slidably connected material receiving frame 17 shakes, and the leaves can be shaken off more effectively onto the ground.

[0048] Specifically, as Figure 1 、 Figure 10 shown, a connecting piece 19 is connected to one side of the bracket 1.

[0049] In the above embodiments, the connecting piece 19 is mounted on a general agricultural machine.

[0050] The working principle of the present invention is as follows.

[0051] Mount this harvester to an agricultural machine via the connecting part 19, and operate the agricultural machine to push this harvester to move. Alternatively, rollers used in the prior art can be installed on this harvester. When the harvester moves in the field, the Chinese medicinal materials first enter the inner side of the feeding plate member 21. The Chinese medicinal materials come into contact with the two clamping blocks 9, pushing the two clamping blocks 9 apart. At this time, the third spring 10 is in a compressed state. The Chinese medicinal materials enter the second inlet groove 11. During the continuous movement of the harvester, the Chinese medicinal materials push the clamping blocks 9 and the sliding blocks 7 to slide. When the clamping block 9 moves to just contact the spreading block 13, the displacement sensor 12 sends out a signal, and accordingly, the first motor 52 operates, driving the gear 51 to rotate. The gear 51 drives the gear ring 53 to rotate, and the gear ring 53 causes the rotating ring 23 to rotate. The connecting rod 24 and the clamping plate 25 on the rotating ring 23 rotate accordingly. Since there are four groups of clamping plates 25 provided on each picking mechanism 2, after the displacement sensor 12 sends out a signal, each first motor 52 only operates a certain amount, so that each group of clamping plates 25 only rotates 90 degrees each time. During the movement of the machine, the Chinese medicinal materials continue to push the clamping blocks 9 and the sliding blocks 7 to slide. The inclined surface of the spreading block 13 acts on the inclined surface of the clamping block 9, causing the two clamping blocks 9 to separate. At this time, the two clamping plates 25 also move above the clamping blocks 9. When the Chinese medicinal materials reach the position of the first inlet groove 26, the two clamping plates 25 pull out and pick the Chinese medicinal materials from the soil. The Chinese medicinal materials cross over the two clamping blocks 9. Due to the action of the second spring 8 and the third spring 10, the sliding block 7 and the clamping block 9 return to their original positions, waiting for the entry of the next Chinese medicinal material plant.

[0052] When the rotating ring 23 rotates 90 degrees, the two clamping plates 25 for clamping the Chinese medicinal materials move to a position close to the arc rod 42. The second motor 61 operates to drive the swing block 62 connected eccentrically to rotate. The swing block 62 moves in the sliding groove 63, causing the shaking frame 4 to perform a reciprocating motion. Each group of arc rods 42 performs an operation of shaking the soil off the Chinese medicinal materials, and the soil directly falls to the ground, reducing the contact between the soil and the machine.

[0053] When the feeding plate member 21 of this picking mechanism 2 enters the next Chinese medicinal material plant, the displacement sensor 12 sends out a signal again, and the rotating ring 23 rotates 90 degrees again. At this time, the clamping plate 25 drives the Chinese medicinal materials to rotate and contact the cutting edge 3. The cutting edge 3 cuts the Chinese medicinal materials. The root part of the Chinese medicinal materials falls onto the receiving table 15 for collection, while the leaf part of the Chinese medicinal materials falls onto the receiving rack 17. With the shaking of the receiving rack 17, the leaves fall to the ground, thus realizing the integrated operations of pulling out and picking the Chinese medicinal materials, shaking the soil off, separating the stems and leaves by cutting, and collecting the roots.

[0054] The above is only a preferred embodiment of the present invention and is not used to limit the protection scope of the present invention.
