A Poria Excavator

technical field

The utility model relates to the field of agricultural machinery, in particular to a tuckahoe excavator.

Background technique

Poria cocos is a commonly used and valuable medicinal material. Its shape is mostly round, oval, oblate or irregular lumps, with different sizes, thin skin, brown or dark brown, rough, wrinkled and constricted. , sometimes partially peeled off. At present, the planting of Poria cocos is mostly artificial cultivation, which can be cultivated by section wood, shrubs and pine needles, but now it is still based on section wood cultivation. Middle-aged pine trees with a diameter of 10-45cm are selected, and they are cut vertically at intervals of 3-7cm. Cut the bark with a width of 3 cm, penetrate deep into the xylem, saw the material when knocking soundly, cut into 65-85 cm long segments, put them in a sunny place, stack them in the shape of a "well" for future use, and choose a gentle slope that is leeward to the sun and slightly acidic and sandy On the ground, dig a cellar with a diameter of 90cm and a depth of 50-65cm. The distance between the cellars is 33cm from top to bottom and 17cm from left to right. Drainage ditches are dug around, and 3-5 wooden sections are taken, with matching thickness, and placed in the cellar in layers. The sections will be arranged in a row, and then inoculated. After the inoculation, the soil will be 4-7 cm thick and piled up in the shape of steamed buns. Usually, the poria cocos will mature 8-10 months after planting. Since the sections are arranged in a row, they will mature. The junction of the later Poria cocos and the section wood is basically on a straight line. It is usually excavated in July-August. It should be matured and harvested in batches without delay. Generally, 15-20 kg of section wood per kiln should be harvested fresh Poria cocos is 2～15 kilograms, and high yield can reach 25～40 kilograms, and output is huge, thereby brought heavy workload when excavating, but, still do not have mechanized Poria cocos excavating machine at present, all are manually excavated. When excavating Poria cocos manually, the soil on the Poria cocos and the section wood is generally removed first with a hoe, and then the junction of the Poria cocos and the section wood is cut with a blade to separate the Poria cocos and the section wood, and then the Poria cocos is excavated with a hoe, and finally the poria cocos is excavated with a shovel. Or a hoe digs the log out of the soil and turns it over to dry, which can then be used as firewood. Manual mining has the following problems:

(1) Due to manual excavation of Poria cocos, the harvesting efficiency is low and the harvesting process is slow. However, the harvesting amount of Poria cocos is large, and the optimal time for harvesting is short. If it cannot be harvested in time, it will affect the quality of Poria cocos. Quality, and then have a strong impact on the selling price, therefore, how to gather Poria cocos quickly and well is very important in the best time for Poria cocos harvesting.

(2) Due to manual excavation of poria cocos, during the harvesting process, the workload is large and the working hours are long, and they are all field work in the field. The working environment is harsh and the work intensity is high, which brings certain health problems to people. Influence.

For the above problems caused by manually digging Poria cocos, it can be seen that the existing technology can no longer meet people's needs.
