Problems solved by technology

[0002] The soil cutting mechanism commonly used in modern potato harvesters, although it can realize the function of cutting the ground and weeds on both sides of the excavation width when the harvester is working, making it easier to excavate the excavation parts, but its disc knife cannot cut The open soil is loosened and does not have the function of separating potato and soil, and the disc cutter cannot deflect with the ground conditions, and cannot avoid various external forces encountered in the work, which will accelerate the wear of the cutter head, shorten the service life, and reduce the cutting efficiency

Abstract

The invention relates to a potato harvester soil cutting mechanism, and belongs to the technical field of potato harvesters. The potato harvester soil cutting mechanism is mainly composed of tool rest welding part, a tool arm welding part, an adjusting spiral assembling part, a tool apron welding part, an upper connecting plate, a cutting disc, a scraper welding part and the like. A tool arm in the tool arm welding part penetrates through a tool arm sleeve on the tool rest welding part, the upper end of the tool arm is connected with the upper connecting plate, the lower end of the tool arm is connected with the tool apron welding part through a bearing base welded to the tool arm, the cutting disc is installed on the tool apron welding part, and a screw rod in the adjusting spiral assembling part penetrates through an installing hole in the upper connecting plate and matched with a nut, arranged in a nut sleeve, of the tool rest welding part. The potato harvester soil cutting mechanism is used for cutting the earth surfaces on the two sides of the excavation breath of the potato harvesters and weeds, the soil excavating depth can be flexibly adjusted, the cutting disc can deviate when encountering external force, and then the abrasion of the cutting disc can be reduced. Scarifying soil is facilitated through the inclined cutting disc, the potatoes and soil can be separated, and the stability of the harvesters in the advancing process can be enhanced.

Description

technical field [0001] The invention belongs to the technical field of potato harvesting machinery, in particular to a mechanism for cutting the ground and weeds on both sides of the digging width of a harvester. Background technique [0002] The soil cutting mechanism commonly used in modern potato harvesters, although it can realize the function of cutting the ground and weeds on both sides of the excavation width when the harvester is working, making it easier to excavate the excavation parts, but its disc knife cannot cut The opened soil is loosened and does not have the function of separating potato and soil, and the disc cutter cannot deflect with the ground conditions, and cannot avoid various external forces encountered in the work, which will accelerate the wear of the cutter head, shorten the service life, and reduce the cutting efficiency. Contents of the invention [0003] In order to solve the above-mentioned shortcomings, the present invention provides a soil...
