Digging angle adjustable excavating mechanism for potato harvester

Abstract

The invention relates to a digging angle adjustable excavating mechanism for a potato harvester and belongs to the technical field of agriculture. The digging angle adjustable excavating mechanism comprises an excavating shovel, a roller type conveyer and a main frame, wherein a first mounting bracket and a second mounting bracket are vertically arranged at the bottom of the main frame in sequence from left to right; 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 fixed pulley is mounted on the main frame above the third mounting bracket; a hydraulic cylinder is horizontally mounted on the main frame on the right side of the fixed pulley; a pull rope is fixed on the third mounting bracket; one end of the pull rope passes by the fixed pulley and is connected with a piston rod of the hydraulic cylinder. The digging angle adjustable excavating mechanism can be used for excavating in different depths for the potatoes grown in different sections, the damage degree and incomplete excavating phenomenon during a potato excavating process are reasonably controlled and the unnecessary crop waste is reduced.

Description

technical field [0001] The invention relates to an adjustable digging mechanism 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, the present invention provides a diggi...

[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.
