Description

Potato seedling harvester Technical Field The utility model belongs to the technical field of agricultural mechanical engineering, and particularly relates to a potato seedling harvester. Background The potato seedling has high nutrient content, and the potato is used as the fourth largest grain crop in China and has high yield. However, the harvesting condition of the potato seedlings is poor, the manual harvesting operation of the potato seedlings is complicated, the efficiency is low, the labor intensity is high, and the industrial production of the silage treated potato seedlings is seriously hindered. Therefore, a high-efficiency potato seedling harvester which is suitable for harvesting high water content is needed to improve the processing efficiency, reduce the labor cost and improve the production automation degree. At present, the existing domestic harvester is generally used for harvesting high-stalk crops such as silage corns and sweet sorghum or low-stalk crops planted on flat land, is not suitable for crops in a ridging planting mode such as potatoes, adopts a modularized design like self-propelled silage abroad, but the silage harvesting equipment is not suitable for harvesting potato seedlings. The harvesting of the potato seedlings is carried out in the mature period of the potatoes, at the moment, the lodging of the stalks is serious, and the existing equipment is used for harvesting, so that the harvesting efficiency is low, the operation cost is high, the impurity content is high, and the quality of the subsequent silage cannot be ensured. Disclosure of utility model The utility model aims to provide a potato seedling harvester, which realizes harvesting and crushing of potato seedlings, ensures that the harvesting part of the potato seedlings is smooth, and ensures that the water content of the potato seedlings is reduced in the crushing process so as to thoroughly crush the potato seedlings. The utility model adopts the following technical scheme that the potato seedling harvester comprises a header, a crushing part and a blower, wherein: the cutting table is used for harvesting potato seedlings and cutting the potato seedlings once, and the conveying device is used for conveying the potato seedlings after the primary cutting to the crushing part; The crushing part is arranged at the rear end outlet of the conveying device and comprises a shell which is horizontally arranged, a roller cutter and a hammer type crushing cutter are arranged in the shell at intervals front and back, and the roller cutter and the hammer type crushing cutter are arranged in a left-right direction and are parallel; An air inlet and a discharge hole are respectively formed on the left shell and the right shell of the shell and behind the hammer type crushing knife; A hot air blower is arranged at the left side outside the shell and at the air inlet, and a hot air outlet of the hot air blower is communicated with the air inlet; The right side outside the shell is provided with a buffer bin which is positioned at the discharge hole and is communicated with the discharge hole, the lower part outside the buffer bin is provided with a blower, the air outlet of the blower is communicated with the buffer bin, the upper part of the buffer bin is connected with a vertical conveying pipe, and the outlet at the upper end of the conveying pipe extends to the blanking collecting device. Further, a bending tube is integrally connected to the upper end of the conveying tube, and the bending tube is U-shaped with a downward opening. Further, the blanking collecting device is a rectangular bin with an open upper end and is used for receiving blown materials. Further, an auger is arranged behind the header, is a horizontally arranged spiral rotating shaft and is parallel to the straw pulling rod, and is used for collecting the potato seedlings cut by the header once to the left or right side and pulling the potato seedlings to the conveying device. Further, the crushing part is arranged on the base, and a crawler-type traveling device is arranged at the lower end of the base. The utility model has the beneficial effects that 1. The hot air blower outputs hot air to the crushing part, thereby ensuring that the water content of potato seedlings is reduced in the crushing process, and the potato seedlings are thoroughly crushed. 2. The crushing part adopts a composite crushing device consisting of a roller cutter and a hammer type crushing cutter to thoroughly crush potato seedlings. 3. The automatic conveying of potato seedlings to the crushing part can be ensured by using a belt conveyor for conveying. 4. The hot air blown by the hot air blower reduces the water content of the potato seedlings, and silage is used as fertilizer after being transported to the blanking collecting device by the air blower, so that the utilization efficiency of nutrient components in the potato seedlings is effectively improved.
