Adjustable frame of potato harvester

Abstract

The invention belongs to the field of agricultural and animal husbandry machinery, and particularly relates to an adjustable frame of a potato harvester. The adjustable frame of the potato harvester has functions that the span is adjustable, the frame is liftable, and operation requirements for different road conditions, work requirements and ground slopes are met. The adjustable frame of the potato harvester comprises a mounting frame, an adjusting rack, a right walking wheel axle, a seat equipped hoist cylinder, a front-rear adjusting rack welding piece, a front-rear adjuster and a span adjusting rack, wherein the adjusting rack is located on the right side of the adjustable frame ad are matched in two positions with the mounting frame for mounting and fixing; the seat equipped hoist cylinder is located on the right side of the adjusting rack, is hinged and fixed with the adjusting rack through a thick hinge pin and in rigid connection and fixation with the right walking wheel axle through a bolt B and a nut B, and a vertical shaft is welded on the seat equipped hoist cylinder and hinged and fixed with the front-rear adjusting rack welding piece; and the front-rear adjusting rack welding piece is located at the front lower part of the seat equipped hoist cylinder, and is connected and fixed in two positions with the mounting frame through the span adjusting rack and the front-rear adjuster.

Description

technical field [0001] The invention belongs to the field of agricultural and animal husbandry machinery, and in particular relates to an adjustable frame on a potato harvester. Adapt to the operation requirements of different slope ground. Background technique [0002] The potato harvester is an important machine for potato harvesting at present. It integrates the functions of harvesting, loosening soil, removing seedlings and loading cars. Some small devices have some of the above functions. The present invention is an adjustable frame body on a potato harvester, and other components such as a traveling mechanism, an excavating mechanism, a transmission system, a shaking mechanism and a sorting component are all installed on the frame body. It is the key component and carrier to ensure the coordinated and reliable work of various components. [0003] Existing potato harvesters are generally small machines with non-adjustable spans. When working, the ground frame with a ...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above-mentioned existing problems, the purpose of the patent of the present invention is to provide an adjustable frame body of a potato harvester, whose span can be adjusted, so that the potato harvester can carry out potato harvesting under conditions of different regions, terrains, and planting methods. Harvesting; the lifting cylinder with seat can be adjusted according to the slope condition, mechanical and hydraulic double action, so that other components, such as excavation mechanism, shaking mechanism, seedling removal mechanism, sorting mechanism and conveying mechanism, are always in a horizontal working state, which solves the problem of slope terrain conditions The problem that one side of the lower side is worn out or stuck can not work, which improves the work efficiency
