DETAILED DESCRIPTION

[0025] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following.

[0026] Embodiment 1

[0027] like Figures 1 to 6As shown, a vibration soil removal and excavation conveying device of a harvester comprises a crawler walking mechanism and a harvester body 1 mounted on the crawler walking mechanism. The crawler walking mechanism drives the entire body to walk in the medicinal field to adapt to the complex terrain for harvesting medicinal materials. A multi-stage vibration soil removal and conveying mechanism is arranged at the front end of the harvester body 1. The multi-stage vibration soil removal and conveying mechanism comprises a conveying frame 2, a hollow conveyor belt, a primary soil removal component and a secondary soil removal component. The rear end of the conveying frame 2 is rotatably mounted on the harvester body 1. The deflection axis of the conveying frame 2 is horizontally arranged. The hollow conveyor belt is installed on the conveying frame 2. The hollow conveyor belt comprises a driving shaft 3 and a driven shaft 4 rotatably mounted on the conveying frame 2. The driven shaft 4 and the driving shaft 3 are spaced apart along the conveying direction of the crop. Two driving sprockets 5 are mounted on the driving shaft 3. Two driven sprockets 6 are mounted on the driven shaft 4. The driven sprocket 6 is connected to the driving sprocket 5 through a chain belt 7. The chain belt 7 is fixed with a plurality of support bars 8 at equal intervals along its own track direction. A soil drop gap is formed between two adjacent support bars 8.A soil-breaking mechanism is arranged in front of the hollow conveyor belt, and the soil-breaking mechanism includes a soil-breaking plate 14 arranged obliquely, and the soil-breaking plate 14 is fixed on the conveying frame 2. A plurality of soil-breaking teeth 15 are evenly distributed and fixed along the length direction of the soil-breaking plate 14 at one end away from the hollow conveyor belt, and the high end of the soil-breaking plate 14 is arranged close to the hollow conveyor belt. The conveying frame 2 deflects downward, so that the soil-breaking teeth 15 on the soil-breaking plate 14 are inserted into the soil layer, and the soil layer is dug up in coordination with the forward movement of the crawler walking mechanism and the upward deflection movement of the conveying frame 2, so that the medicinal materials carrying the soil fall on the hollow conveyor belt, and the hollow conveyor belt transports the medicinal materials carrying the soil to the rear of the harvester. During the transportation process, the soil and the medicinal materials are separated by the first-level soil removal component, and the separation of the soil and the medicinal materials is accelerated by the second-level soil removal component, and the separated soil is shaken off the hollow conveyor belt. Specifically, a plurality of first-level soil removal components are arranged at intervals along the conveying direction of the hollow conveyor belt, and the first-level soil removal component is arranged above the hollow conveyor belt. The first-level soil removal component includes a soil breaking shaft 9 and a rotating disk 10. Both ends of the soil breaking shaft 9 are fixedly connected with the rotating disk 10. A plurality of soil breaking shafts 9 are evenly distributed along the circumferential direction of the rotating disk 10. The rotating disk 10 is rotatably installed on the conveying frame 2, and the rotating disk 10 drives the soil breaking shaft 9 to rotate. The soil shaft 9 hits the soil. Since the stems and leaves of the medicinal materials are relatively flexible, the medicinal materials will bend adaptively after the soil-breaking shaft hits them, and will not be damaged. After the soil-breaking shaft hits the soil, large pieces of soil will be broken, which is convenient for the secondary soil removal component to vibrate and make the broken soil fall. A plurality of primary soil removal components are arranged along the conveying direction, which has a better soil removal effect. Secondly, the secondary soil removal component is arranged in the annular space of the chain belt 7. The secondary soil removal component includes a vibration shaft 11 and a roller 12. The vibration shaft 11 is rotatably installed on the conveying frame 2. The vibration shaft 11 is fixed along its own axial direction with a plurality of vibration rings 13. The side wall of the vibration ring 13 is fixed along its own circumferential direction. There are multiple rollers 12, the vibration shaft 11 drives the vibration ring 13 to rotate, and the vibration ring 13 drives the rollers 12 to rotate. The rollers 12 will cyclically hit the support bar 8 during the rotation process, so that the support bar 8 moves up and down to generate vibration, which separates the soil from the medicinal materials on the one hand, and shakes the separated soil off the hollow conveyor belt on the other hand, so as to achieve rapid soil removal of the medicinal materials, improve the soil removal effect and efficiency, and do not need manual soil removal in the future, thus reducing labor costs; through the mutual cooperation of the primary soil removal component and the secondary soil removal component, the automatic soil removal and harvesting operation can be completed quickly and effectively, which improves the harvesting efficiency and effect of the medicinal materials. ;

[0028] Embodiment 2

[0029] Based on the first embodiment, Figure 1 and Figure 3As shown, a positioning roller 53 is provided at the front end of the earth-breaking mechanism, and the positioning roller 53 is located above the earth-breaking mechanism. Adjustable mounting plates 54 are fixed at both ends of the positioning roller 53, and the adjustable mounting plates 54 are installed on the conveying frame 2 by bolts. Since the driver sits in the cab of the harvester body 1, and the vibrating soil removal and conveying mechanism deflects downward to dig soil, it is difficult for the driver to see the relative position of the earth-breaking plate 14 and the ground, and it is difficult to control the digging depth. The setting of the positioning roller 53 facilitates the driver to indirectly locate the position of the earth-breaking plate 14. The positioning roller 53 is installed at a corresponding angle according to the digging depth. The adjustable mounting plate 54 can be deflected up and down by loosening the bolts to adjust the height of the positioning roller 53, so as to adjust the relative height between the positioning roller 53 and the earth-breaking plate 14. Since the positioning roller 53 is located above the earth-breaking plate 14 and at the front of the harvester, the driver can see the positional relationship between the positioning roller 53 and the ground, and can roughly know the position of the earth-breaking plate 14 through the position of the positioning roller 53, so that the degree of downward deflection of the conveying frame 2 can be well controlled to achieve a better harvesting effect.

[0030] Embodiment 3

[0031] Based on the second embodiment, Figure 1 As shown, the conveying frame 2 includes a left mounting plate 16, a right mounting plate 17 and a mounting shaft 18, the left mounting plate 16 and the right mounting plate 17 are both gap-mounted on the mounting shaft 18, the mounting shaft 18 is rotatably connected to the harvester body 1, and the multi-stage vibration soil removal and conveying mechanism is arranged between the left mounting plate 16 and the right mounting plate 17, the side wall of the left mounting plate 16 and the side wall of the right mounting plate 17 are both hinged with a lifting hydraulic cylinder 19, the cylinder body of the lifting hydraulic cylinder 19 is hinged on the harvester body 1, and the entire multi-stage vibration soil removal and conveying mechanism is driven to deflect up and down by the extension and retraction of the lifting hydraulic cylinder 19 to change the position height of the multi-stage vibration soil removal and conveying mechanism. When the harvester is moving normally, the multi-stage vibration soil removal and conveying mechanism is left from the ground, and when harvesting, the multi-stage vibration soil removal and conveying mechanism is deflected downward to dig up the soil layer.

[0032] Embodiment 4

[0033] Based on the third embodiment, Figure 1 and Figure 3As shown, a collecting bucket 20 is arranged on the harvesting machine body 1, and a conveying assembly is arranged at the output end of the hollow conveyor belt, and the output end of the conveying assembly is located just above the collecting bucket 20, and the conveying assembly includes a horizontal conveyor belt 21 and an inclined conveyor belt 22, and the horizontal conveyor belt 21 is located below the output end of the hollow conveyor belt, and a V-shaped bucket 23 is fixed on the harvesting machine body 1, and the output end of the horizontal conveyor belt 21 extends into the V-shaped bucket 23, and the input end of the inclined conveyor belt 22 extends into the V-shaped bucket 23, and a mounting frame 24 is fixed on the harvesting machine body 1, and the collecting bucket 20 is hinged on the mounting frame 24, and a discharge hydraulic cylinder 25 is hinged on the mounting frame 24, and the telescopic shaft of the discharge hydraulic cylinder 25 is hinged on the collecting bucket 20; because the width of the multi-stage vibration soil removal and conveying mechanism needs to be designed to be larger, the width that can be excavated and covered is larger, and the harvesting efficiency can be improved, but the opening size of the collecting bucket 20 does not need to be designed to be larger, otherwise it will cause space waste, so directly passing Transporting the medicinal materials to the collecting barrel 20 through the hollow conveyor belt will cause some of the medicinal materials to be unable to enter the collecting barrel 20. Therefore, it is necessary to transfer the medicinal materials through the conveying assembly, and the horizontal conveyor belt 21 is used to carry the harvested and soiled medicinal materials, and the conveying direction of the horizontal conveyor belt 21 is perpendicular to the conveying direction of the hollow conveyor belt, so that the horizontal conveyor belt 21 corresponds to the width direction of the hollow conveyor belt in the length direction, so that the horizontal conveyor belt 21 can completely receive the medicinal materials transported by the hollow conveyor belt, and the horizontal conveyor belt 21 transports the medicinal materials to the V-shaped bucket 23, and then the medicinal materials in the V-shaped bucket 23 are transported to the collecting barrel 20 through the inclined conveyor belt 22, and the width of the inclined conveyor belt 22 is smaller than the opening width of the collecting barrel 20, to ensure that the medicinal materials can be completely transported to the collecting barrel 20; when the harvesting is completed and unloading is required, the unloading hydraulic cylinder 25 extends to drive the collecting barrel 20 to deflect, so that the collecting barrel 20 pours out the medicinal materials in it, completes automatic unloading, and realizes fully automated harvesting.

[0034] Furthermore, if Figures 1 to 4As shown, the inclined conveyor belt 22 includes an inclined frame 26, a driving shaft a and a driven shaft a, the driving shaft a and the driven shaft a are both rotatably mounted on the inclined frame 26, two driving sprockets a27 are sleeved on the driving shaft a along its own axial direction, and two driven sprockets b28 are sleeved on the driven shaft a along its own axial direction, and the driving sprocket a27 is connected to the driven sprocket b28 through a vibrating chain 29, and a plurality of vibrating conveying bars 30 are arranged between the two vibrating chains 29, and the plurality of vibrating conveying bars 30 are arranged at equal intervals along the conveying direction of the vibrating chains 29, and a plurality of hook teeth 31 are fixed at equal intervals on the top of the vibrating conveying bars 30 along its own length direction, and a toggle shaft 32 is arranged in the annular space of the vibrating chain 29, and an arc plate 33 is fixed on the bottom of the vibrating conveying bar 30, and the toggle shaft 32 is located above the arc plate 33. On the moving path, multiple vibrating conveying bars 30 are set to make the inclined conveyor belt 22 hollow, so that the soil mixed in the medicinal materials can be further shaken off during the conveying process. Specifically, the active shaft a drives the active sprocket a27 to rotate, and the active sprocket a27 drives the driven sprocket b28 to rotate through the vibrating chain 29, so that the medicinal materials are conveyed to the collecting bucket 20. During the conveying process, the vibrating conveying bar 30 carrying the medicinal materials will drive the arc plate 33 thereon to move close to the toggle shaft 32. After the arc plate 33 collides with the toggle shaft 32, it will drive the vibrating conveying bar 30 to move upward. After the arc plate 33 passes through the toggle shaft 32, the vibrating conveying bar 30 is reset, so that the vibrating conveying bar 30 and the vibrating chain 29 vibrate, which can effectively shake off the soil mixed between the medicinal materials and further improve the soil removal effect.
