Description

Technical Field

[0001] The present invention relates to the technical field of Chinese medicinal material collection, in particular to a device for collecting rhizome Chinese medicinal materials. Background Art

[0002] During the cultivation and harvesting of Chinese medicinal herbs, the digging of rhizomes (such as ginseng, astragalus, and licorice) has long relied on traditional manual labor or semi-mechanized equipment. Existing digging equipment generally suffers from low cleanup rates. Traditional equipment has a simple screening structure, and Chinese medicinal materials are easily retained during transportation due to adhesion of broken soil or clogging of grooves, affecting harvesting efficiency and quality.

[0003] Furthermore, the equipment's structural strength is insufficient, making it prone to deformation or fracture during operations in complex terrain or during high-intensity operations. The excavator blade and tail are particularly susceptible to fatigue damage due to concentrated forces. Furthermore, the fixed tires lack height adjustment, making it difficult to adapt to varying soil depths, resulting in insufficient contact between the excavator blade and the soil surface. Regarding power transmission efficiency, transmission components such as sprockets and gears are mostly single-stage, resulting in significant power loss and no longer meeting the current requirements for efficient mechanized mining.

[0004] Therefore, the present invention proposes a digging equipment with high transmission efficiency and multi-level power output, which further improves the clean picking rate of Chinese medicinal materials. Summary of the Invention

[0005] In order to further improve the cleaning rate and work efficiency during the harvesting of Chinese medicinal materials, optimize the machine structure, enhance the equipment strength, and reduce the failure rate during the operation, the following technical solutions have been derived.

[0018] 2. The reinforcement component adopts a triangular force-bearing structure composed of a tripod and a pull rod, combined with the horizontal connection of the hollow frame and the suspension frame, which greatly improves the body's anti-deformation ability and ensures the stability of the equipment under complex terrain or high-intensity operations;

[0019] 3. The lifting assembly drives the tire height adjustment through the oil cylinder, so that the excavator can always fit the soil surface at different depths, reducing operation resistance and improving excavation accuracy;

[0020] 4. The eccentric link swing structure of the tail wing further separates the residual soil blocks through lateral swing, reducing the residue;

[0021] 5. The No. 1 transmission module directly drives the silicone strip of the toggle assembly to produce an active stirring effect, effectively shaking off the broken soil on the roots of Chinese medicinal materials and preventing the screen from getting stuck at the junction;

[0022] 6. The speed increasing gear of the No. 2 linkage module - the synchronous belt drive drives the turbine to rotate at high speed. Cooperating with the heat transfer oil circulation system in the solar heat collecting oil chamber, it not only dries the water stains on the surface of the Chinese medicinal materials, but also reduces additional energy consumption, significantly improving operation efficiency and environmental adaptability.

[0023] 7. The whole machine relies on the tractor power shaft to achieve fully automatic operation, reducing manual intervention; the modular design facilitates maintenance and replacement, reduces the failure rate, and meets the needs of efficient mechanized operations in large-scale planting.

The No. 2 linkage main gear 1801 rotates following the No. 2 transmission compression sprocket 904, and the No. 2 linkage main gear 1801 then transmits power to the No. 2 linkage sub-gear 1802 meshing with it (this process is a speed-increasing transmission, and a suitable transmission ratio is designed according to actual needs).

[0042] Working principle: The whole device is installed on a tractor (it can be hoisted or bolted), and the tractor's power shaft is connected to the drive assembly. The power output by the tractor controls the rotation of the worm gear 601 and transmits power to the worm 602, so that the output shaft 603 simultaneously outputs power to the No. 1 transmission module and the No. 2 transmission module, and then transmits power to the primary screen assembly and the secondary screen assembly respectively, so that the primary mesh belt 803 and the secondary mesh belt 1003 are continuously driven under the action of the continuously rotating primary roller 801, primary rubber wheel 802, secondary roller 1001 and secondary rubber wheel 1002;

[0043] At the same time, the secondary screen assembly transmits power to the No. 1 linkage module, and the No. 1 linkage main sprocket 1101, the No. 1 linkage secondary sprocket 1102 and the No. 1 linkage chain belt 1103 continuously transmit power and output power to the eccentric shaking assembly. By utilizing the arrangement of the linkage shaft 1201 and the eccentric sleeve 1202, the No. 1 connecting rod 1301 in the connecting rod assembly continuously swings, driving the No. 2 connecting rod 1303 and the No. 3 connecting rod 1304 to swing synchronously, thereby realizing the lateral swinging movement of the tail wing 14;

[0044] In addition, the power is transmitted to the toggle assembly through the No. 1 transmission compression sprocket 704, and the No. 2 transmission compression sprocket 904 transmits the power to the No. 2 linkage module. Then, the No. 2 linkage main gear 1801, the No. 2 linkage sub-gear 1802, the No. 2 main synchronous gear 1803, the No. 2 sub-synchronous gear 1804 and other speed-increasing transmission structures on the No. 2 linkage module are used to rotate the turbine 19 at high speed, so that the heat transfer oil circulates between the oil chamber 17 and the swing arm 1601, and transfers heat to the silicone strip 1602.

[0045] The tractor carries the machine in the field, and the shovel 5 is extended into the soil surface to dig out the corresponding Chinese medicinal materials. After the Chinese medicinal materials enter the primary mesh belt 803, the root soil is shaken off during the transportation process. Part of the Chinese medicinal materials passing through the primary mesh belt 803 are provoked by the silicone strip 1602 on the continuously rotating swing arm 1601 and thrown onto the secondary mesh belt 1003. As the secondary mesh belt 1003 continues to transport, the Chinese medicinal materials fall on the tail wing 14. During the swinging process of the tail wing 14, the Chinese medicinal materials and the surface of the tail wing 14 continue to produce relative motion. This dynamic contact will peel off the broken soil and impurities attached to the surface of the Chinese medicinal materials through inertia and shear force, and has an efficient cleaning effect on soil particles with strong adhesion.
