Description

Technical Field

[0001] This utility model relates to the field of medicinal herb harvesting technology, specifically a traction harvesting device suitable for purple Angelica dahurica. Background Technology

[0002] Angelica dahurica, as one of the first major Chinese medicinal herbs to be included in the list of herbs that can be used both as medicine and food, is an important raw material for traditional Chinese medicine preparations and food flavorings. Its applications are very wide-ranging, possessing not only medicinal value such as dispelling wind and cold, promoting blood circulation and draining pus, promoting tissue regeneration and relieving pain, drying dampness and stopping leukorrhea, and lowering blood pressure, but also beauty and body-shaping value such as weight loss, cosmetic enhancement, and freckle removal. It is also a typical example of medicine and food sharing the same origin, and can be used in porridge, soup, and seasoning, possessing high edible value.

[0003] Sichuan Angelica dahurica is one of the commercial varieties of Angelica dahurica, with a large annual output and superior quality, and is also one of the major authentic medicinal materials of Sichuan. Sichuan Province has a complex topography with significant differences in altitude and soil environment across the province. Sichuan Angelica dahurica is mainly cultivated in relatively flat cities and counties such as Mianyang, Deyang, Suining, and Nanchong, with Suining Sichuan Angelica dahurica being the most authentic. Its original production area is mainly located in the relatively flat alluvial soil area along the banks of the Fujiang River. However, with the advancement of urbanization and the adjustment of agricultural industrial structure, its planting area has gradually shifted to the hilly purple soil areas surrounding the traditional production areas, and its production technology is also facing major adjustments.

[0004] In hilly purple soil areas, due to the high viscosity and tendency to compact, traditional harvesting methods primarily rely on manual labor. In recent years, harvesting machinery from Anhui and other regions has been introduced to assist in harvesting, mainly used in sandy areas or alluvial soil areas along rivers (where the soil has a sand content of over 30% and is loose; harvesting is completed through turning, conveying, shaking, and sorting). Traditional harvesting machinery in purple soil areas faces the following main problems: First, the harvesting devices are large and heavy, requiring significant power; second, due to the high viscosity of the purple soil, the harvesting depth is insufficient (reduced from 30cm to about 25cm under the same power), resulting in substantial damage to Angelica dahurica; third, separation of the herb and soil is difficult during harvesting, with a recovery rate of only about 60%. Therefore, we propose a traction harvesting device suitable for Angelica dahurica in purple soil areas. Utility Model Content

[0005] The purpose of this invention is to provide a traction excavation device suitable for purple soil Angelica dahurica, in order to solve the problems mentioned in the background art, such as the large size and weight of the excavation machinery, insufficient excavation depth causing a large amount of damage to Angelica dahurica and difficulty in separating the medicinal material from the soil.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a traction excavation device suitable for harvesting purple angelica dahurica, comprising a main body, the main body including side guard plates, a main shaft base, and a frame, the frame being disposed above the side guard plates, with both ends of the frame welded to the side guard plates, the main shaft base welded to one side of the top of the frame, a main drive shaft mounted inside the main shaft base via bearings, a traction drive motor mounted at the center of the frame, and the output end of the traction drive motor fixedly connected to the main drive shaft, a primary vibration transmission mechanism disposed below the side guard plates, and a soil-penetrating shovel with an angle of seven degrees mounted between the side guard plates on one side of the primary vibration transmission mechanism, the primary vibration transmission mechanism including a primary vibration transmission shaft, ... The device comprises a primary drive belt, a primary drive rod, and a primary vibration support plate. The primary vibration drive shaft is mounted under the device side guard plates via bearings. The primary drive belt is fitted over the outside of the primary vibration drive shaft. The primary drive rod is positioned between the primary drive belts. The primary vibration support plate is fixed to the outer walls at both ends of the primary vibration drive shaft. A secondary vibrating screen mechanism is located between the device side guard plates on the other side of the primary vibration drive mechanism. The secondary vibrating screen mechanism includes a secondary vibrating drive shaft, a secondary vibrating support plate, and secondary vibrating screen rods. The secondary vibrating drive shaft is mounted between the device side guard plates on one side of the primary vibration drive mechanism via bearings. The secondary vibrating support plate is fixed to the outer wall of the secondary vibrating drive shaft. The secondary vibrating screen rods are distributed on the outer side of the secondary vibrating support plate.

[0007] Preferably, upper stabilizing bars are provided on both sides of the frame, and one end of the upper stabilizing bar is welded to the frame, while the other end of the upper stabilizing bar is welded to the inner wall of the device side guard plate.

[0008] Preferably, there are two primary vibration drive shafts. The end of the primary vibration drive shaft near the main drive shaft extends to the outside of the device side guard plate and is connected to the main drive shaft via a primary drive chain.

[0009] Preferably, the primary drive belt is provided in three sets and distributed at both ends and the center of the surface of the primary vibration drive shaft, and the surface of the primary drive belt is provided with equally spaced threaded holes.

[0010] Preferably, both ends of the primary transmission rod extend to the surface of the primary transmission belt and are fixedly connected to the primary transmission belt with bolts, and the primary transmission rod is welded to the primary vibration support plate.

[0011] Preferably, there are two secondary vibration drive shafts, and one end of each secondary vibration drive shaft extends to the outside of the device side guard plate and is connected to the primary vibration drive shaft via a secondary drive chain.

Compared to traditional medicinal herb harvesting machines, this device is lighter, requires less power, and has more power margin. Under the same working conditions, this device can achieve high-power harvesting, thereby improving harvesting efficiency. A two-stage dual-vibration separation mechanism is constructed by designing a primary vibration transmission mechanism and a secondary vibrating screen mechanism to separate medicinal materials from soil. The traction drive motor drives the main drive shaft to rotate, which in turn drives the primary vibration transmission shaft to rotate via a primary transmission chain. The primary vibration transmission shaft then drives the secondary vibration transmission shaft to rotate via a secondary transmission chain. By setting up the primary vibration transmission mechanism, the rotation of the primary vibration transmission shaft causes the primary transmission belt to drive the primary transmission rod to rotate, thus conveying and separating the medicinal materials from the soil. By setting up the secondary vibrating screen mechanism, the rotation of the secondary vibration transmission shaft causes the secondary vibration support plate to drive the secondary vibrating screen rod to rotate, further separating the medicinal materials from the soil. The two-stage dual-vibration separation mechanism achieves efficient separation of medicinal materials from soil, greatly improving the excavation efficiency. By setting the entry shovel to a seven-degree angle and optimizing the entry angle, the excavation depth can be effectively increased under heavy clay soil conditions, thus reducing the damage rate of medicinal materials.
