Lightweight Potato Segmental Harvester Micro Potato Floating Crushing Device

Abstract

The invention provides a light and simple potato segmental harvester micro-potato floating crushing device, which includes a mounting frame, a feeding device, a crushing device and a floating detection device, and is characterized in that the crushing device includes a ground wheel shaft, a ground wheel, and a drive shaft , extrusion wheel, crushing knife and drive motor, and the ground wheel and extrusion wheel are located in the same plane, and the lower generatrix of the extrusion wheel is 50-100mm higher than the lower generatrix of the ground wheel, and more "J" shaped crushing The knife is installed on the hub of the extrusion wheel, and the protruding end of the driving shaft installed with the extrusion wheel passes through the floating arm I and is connected with the output shaft of the driving motor installed on the floating arm I through a coupling, and the floating detection device The end of the cylinder rod of the hydraulic cylinder is hinged and fixed on the floating arm II, the end of the telescopic rod of the linear displacement sensor is hinged on the floating arm II, and is close to the hinge of the cylinder rod of the hydraulic cylinder on the floating arm II. The invention can automatically pulverize micro-potatoes, and has smooth obstacle avoidance, efficient pulverization, strong practicability and good working reliability.

Description

technical field [0001] The invention provides a light and simple segmented potato harvester and a micro-potato floating crushing device, which is mainly used for crushing the micro-potatoes of the light and simple segmented potato harvester. Background technique [0002] The light and simple potato segmental harvester is an indispensable harvesting machine in many small plots and hilly mountainous potato planting areas in China, and is the key equipment to improve the overall level of potato mechanization in China. The survey found that during the operation of the light and simple potato segmental harvester, the pole-type separator is generally used to complete the separation of potato and soil. However, the potatoes with small triaxial size can fall through the sieve to the surface or be buried in the soil. At the same time, in the process of mechanized harvesting, green-headed potatoes, diseased potatoes, rotten potatoes, and deformed potatoes, etc. remain in the field thr...

Problems solved by technology

If these micro-potatoes are harvested and stored as starch potatoes for processing, the starch content will be less, and the cost of starch extraction and processing is far greater than its commercial value, and even some micro-potatoes are harmful to human health.

More importantly, the smaller micro-potatoes fall to the harvest surface and are buried in the soil. Under the conditions of suitable temperature and sufficient water, they will often germinate and grow in the next year, which has a great impact on the potato planting environment.

On the one hand, micro-potatoes have changed the original intention of mechanized precision sowing to a certain extent, that is, changing the planting density required by potato planting agronomy, and competing with normal sowing potatoes for water and fertilizer, which greatly affects the standardization of potato mechanized field management, especially before and after In the case of two-year planting variety changes, it is easy to cause cross-mixing of potato varieties, which is not conducive to the selection of improved varieties and the promotion of standardized planting; result in negative effect
