A cassava bionic harvester

Abstract

The invention discloses a cassava bionic harvester, which belongs to the technical field of agricultural machinery. Including frame, bionic shovel mechanism, angle adjustment mechanism and shaking soil and potato separation mechanism; the upper and lower curves of bionic shovel teeth are divided into bionic shovel tooth section and gentle soil lifting shovel tooth section, among which, cutting the shovel tooth section with any horizontal plane, The curves obtained from the two side surfaces are designed to be bionic curve structures according to the relative motion trajectory of the soil. The entire shovel tooth is designed as a curved surface, wherein the design of the upper edge and the lower edge of the shovel tooth is respectively designed according to the contours of the upper edge and the lower edge of the toe of the soil animal. The angle adjustment mechanism completes the angle adjustment by adjusting the length of the bolt at the upper end of the shovel handle. The front and rear ends of the rack are designed with porous positions to adapt to the unevenness of the soil surface. The vibrating soil and potato separation device is driven by clean energy electricity, and when the transmission chain moves backwards, it uses the cam to vibrate the transmission chain to achieve soil throwing. After being excavated by the bionic shovel and conveyed and separated by the shaking separation device, the excavation of cassava roots and the separation of soil and potatoes can be completed.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery and relates to a harvester, in particular to a cassava bionic harvester. Background technique [0002] The mechanization of cassava harvesting will be one of the main trends in cassava in my country. The mechanization of cassava harvesting will not only help improve the production efficiency of the cassava industry, but also promote the development of the cassava industry in my country. The digging shovel is a key component of the cassava harvester. How to improve the problem of soil adhesion and resistance when the digging shovel is working, so that the digging shovel has good soil penetration, soil removal and drag reduction is a major problem in optimizing the design of the digging shovel. difficulty. [0003] Existing excavating shovels have unsatisfactory soil-discharging functions, and the more soil is attached, the greater the traction force required. This not only affects t...

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the excavating shovel of the existing cassava harvester has a single form and a complex structure, and when digging cassava tubers, the ability of broken soil and soil leakage is limited, the resistance to entry into the soil is relatively large, and the rate of potato damage and potato leakage is high; pollution serious problem
