Device for digging out root-tuber crops

Abstract

The invention relates to the field of agricultural machinery, in particular a device for digging out root-tuber crops. The device for digging out the root-tube crops comprises row teeth which are arranged in an inclined manner, wherein the row teeth are fixed on a cross rod, the cross rod is connected with the support, a swinging plate is arranged at each interval between the row teeth, the swinging plates are fixed on a spindle, the spindle is arranged above the cross rod, one end of the cross rod is fixedly connected with a first connecting rod, the other end of the first connecting rod is hinged with a second connecting rod, the other end of the second connecting rod is connected with an eccentric wheel, and the eccentric wheel is connected with a transmission mechanism; at least two supporting bodies are fixed on the cross rod, holes are punched in the supporting bodies, and the spindle sequentially passes through at least two holes to be supported. The device provided by the invention has the beneficial effects that the swinging plates rotate at a certain angle in a reciprocating manner, and weeds, mulches and soil blocks are thrown off and are not accumulated at the peripheryof the row teeth; and the problem that the weeds or mulches are twined can not be produced when digging is carried out for a long time by adopting the device provided by the invention.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and relates to digging equipment for harvesting medicinal materials such as licorice and codonopsis pilosula, or tuber crops such as potatoes and sweet potatoes. Background technique [0002] Underground root crops, such as licorice, Codonopsis pilosula, potatoes, sweet potatoes, etc., need to be dug out of the soil. Now under the situation of large-scale planting, it is all harvested by excavating machinery, and the main mechanism is a shovel or a fork. Weeds are unavoidable in the field, and now mulch is commonly used. When a shovel or fork is used for operations, it will cause weeds or mulch to be entangled on the shovel or fork. At the same time, soil particles are also mixed in the weeds or mulch. The extension of the crops will become more and more hard, and it is necessary to stop and clean them. If they are not cleaned, the travel resistance will be increased, the excavati...

Problems solved by technology

Weeds are unavoidable in the field, and now mulch is commonly used. When a shovel or fork is used for operations, it will cause weeds or mulch to be entangled on the shovel or fork. At the same time, soil particles are also mixed in the weeds or mulch. The extension, more and more, harder, need to stop and clean, if not cleaned, it will increase the resistance of travel, reduce the depth of excavation, affect the excavation of crops, and cause the problem of broken roots or no digging.
