Description

Technical Field

[0001] The invention belongs to the technical field of Chinese medicinal material harvesting machinery, and in particular relates to a separate shaking type root-soil separation device. Background Art

[0002] Ophiopogon japonicus is a small root herb commonly used in traditional Chinese medicine. It is widely used in traditional Chinese medicine and is the raw material for many Chinese patent medicines. Ophiopogon japonicus is cultivated on a large scale in Sichuan, Zhejiang, Shandong and other places. During the harvesting process, due to its strong soil-holding ability and strong cohesion, the tubers are difficult to separate from the soil. Manual harvesting is inefficient and costly. When using the commonly used Chinese herbal root harvester on the market, the Ophiopogon japonicus is dug up with a large amount of soil, which affects the efficiency and quality of Ophiopogon japonicus processing.

[0018] 1. Through the eccentric structure design of the crankshaft at different angles, each shaking rod realizes a staggered vertical and horizontal movement. The adjacent shaking rods cooperate with each other to achieve the beating and transportation of the soil mixture. Compared with the traditional vibration chain and vibration screen conveying separation, the staggered shaking conveying method is more conducive to breaking the bonding balance between soil layers and has a better soil crushing effect.

[0019] 2. The kneading device works together with a brush and a spiral mesh bottom plate. The brush forces the Ophiopogon japonicus tubers to move in a spiral motion along the mesh plate. The kneading between the brush and the surface of the mesh plate removes relatively small soil particles attached to the surface of the tubers. Compared with ordinary root and tuber harvester devices, the newly added kneading device can further reduce the amount of soil carried by the Ophiopogon japonicus tubers after vibration separation.

The shaking motor 15 drives the shaking active sprocket 12 to rotate, and then drives the shaking driven sprocket 14 to rotate through the shaking chain 13. The driven sprocket 14 drives the active crankshaft 19 to rotate by a key connection to transmit power. The power of the rotation of the active crankshaft 19 is transmitted to the driven crankshaft 16 through the shaking rod 18. The active crankshaft 19 and the driven crankshaft 16 rotate in coordination, and the shaking rod installed between the two shafts performs column-type shaking, beating and alternating transportation at different heights. The mixture of Ophiopogon japonicus and soil that has undergone the initial root-soil separation is fed into the kneading device through the guide plate 23. The kneading motor 4 drives the kneading active sprocket 6 to rotate, and then drives the kneading driven sprocket 8 to rotate through the kneading chain 7. The driven sprocket 8 drives the kneading shaft 20 to rotate by transmitting power through a key connection, driving the connected rotating plate 21 and brush bar 22 to rotate together. Under the pressure of the brush bar 22, the Ophiopogon japonicus plant is kneaded along the spiral strips 25 and mesh holes on the spiral mesh plate 24 to remove the soil attached to the Ophiopogon japonicus tubers. The soil particles fall from the mesh holes on the spiral mesh plate 24, and the Ophiopogon japonicus plant is finally collected by falling from the collection outlet at the bottom center of the spiral mesh plate 24.
