Micro miscellaneous potato floating crushing device for light and simple potato segmented harvester

Abstract

The invention provides a micro miscellaneous potato floating crushing device for a light and simple potato segmented harvester. The micro miscellaneous potato floating crushing device comprises a mounting rack, a feeding device, a crushing device and a floating detection device, and is characterized in that the crushing device comprises a land wheel shaft, a land wheel, a driving shaft, an extrusion wheel, crushing knives and a driving motor; the land wheel and the extrusion wheel are located in the same plane; a lower bus of the extrusion wheel is 50-100 mm higher than the lower bus of the land wheel; a plurality of J-shaped crushing knives are mounted on a hub of the extrusion wheel; the extending end of a driving shaft provided with the extrusion wheel after penetrating through a floating arm I is connected with an output shaft of a driving motor mounted on the floating arm I through a coupler; the end of a cylinder rod of a hydraulic cylinder of the floating detection device is hinged and fixed to a floating arm II; and the end of a telescopic rod of a linear displacement sensor is hinged to the floating arm II and is close to the hinged position of the cylinder rod of the hydraulic cylinder on the floating arm II. The micro miscellaneous potato floating crushing device for the light and simple potato segmented harvester can automatically crush micro miscellaneous potatoes,and is smooth in obstacle avoidance, efficient in crushing, high in practicability and good in 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
