Hydraulic adjustable excavating, separating and harvesting device for potato harvester

Abstract

The invention relates to a hydraulic adjustable excavating, separating and harvesting device for a potato harvester and belongs to the technical field of agriculture. The hydraulic adjustable excavating, separating and harvesting device comprises an excavating shovel, a roller type conveyer and a main frame, wherein a first mounting bracket and a second mounting bracket are arranged at the bottom of the main frame; a third mounting bracket is hinged on the left side of the first mounting bracket; the excavating shovel is mounted on the third mounting bracket; a mounting base is fixed at the bottom of the main frame; a hydraulic cylinder is mounted at the bottom of the mounting base; a cylinder body of the hydraulic cylinder is hinged on the mounting base; a piston rod of the hydraulic cylinder is hinged on the third mounting bracket; the roller type conveyer is composed of a first roller conveyer and a second roller conveyer which are in transmitting fit with each other; a lifting conveyer in feeding fit with the second roller conveyer is arranged at the right outlet end of the second roller conveyer; a receiving slot is mounted on the main frame corresponding to a discharging port at the top of the lifting conveyer. The hydraulic adjustable excavating, separating and harvesting device can be used for excavating in different depths for the potatoes grown in different sections and the unnecessary crop waste is reduced.

Description

technical field [0001] The invention relates to a hydraulically adjustable digging, separating and harvesting device for a potato harvester, which belongs to the field of agricultural technology. Background technique [0002] Potato crops are one of the main economic crops for farmers in the north. Because the soil in the north is mostly sandy soil, the taste of potatoes grown is better than that of other places, and the yield is also large, so more and more potatoes are planted in the sandy soil areas of the north. With the increase of output, people have more and more requirements for potato harvesters. Commonly used potato harvesters have gradually been unable to meet people's needs, especially in the excavation part. Potatoes grow at different depths. If digging with the same digging mechanism, the potatoes may be damaged or some potatoes will not be fully dug, resulting in unnecessary waste of crops. Contents of the invention [0003] In view of the above problems, t...

[0002] Potato crops are one of the main economic crops for farmers in the north. Because the soil in the north is mostly sandy soil, the taste of potatoes grown is better than that of other places, and the yield is also large, so more and more potatoes are planted in the sandy soil areas of the north. With the increase of output, people have more and more requirements for potato harvesters. Commonly used potato harvesters have gradually been unable to meet people's needs, especially for the excavation part. Potatoes grow at different depths. If you dig with an excavating mechanism with the same digging depth, it is likely to damage the potatoes or some potatoes will not be dug completely, resulting in unnecessary waste of crops.
