A device for double ear picking and stem and leaf impurity removal for fresh corn with two ears

Abstract

A double ear fresh-eating corn secondary ear picking and stem and leaf impurity removal device belongs to agricultural machinery; a fan casing and a secondary ear picking roller assembly are sequentially installed on a harvesting rack from top to bottom, and the fan is installed on the fan Axial-flow wind dust collector is installed on the central part of the lower side of the casing, and the lower port of the axial-flow wind dust collector faces the secondary ear picking roller assembly, and a tangential wind dust collector is installed on the circumferential tangent part of the fan casing. The outlet tube, the fan impeller shaft assembly with the fan blade is installed in the fan casing, and the groove-shaped cutting edge is provided on the outer end of the fan blade, and the cutting edge is installed on the inner wall of the fan casing. The fixed knife for tearing and smashing, the fixed knife for cutting and smashing and the groove-shaped cutting and tearing edge are cross-inserted and overlapped to cooperate or disengage; this device is equipped with a secondary ear picking roller assembly and a stem and leaf remover according to the growth characteristics of fresh corn with two ears. The miscellaneous fan mechanism has the characteristics of high ear picking yield and good ear cleanliness.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a double-ear fresh corn ear picking and impurity removal operation assembly that can be assembled on a fresh corn combined harvester. Background technique [0002] In recent years, with the increase in the demand for fresh corn, the planting area of ​​fresh corn has expanded rapidly, and the mechanized harvesting of fresh corn has been put on the work schedule. At present, the mechanized harvesting of fresh corn mostly uses traditional corn harvesting machines to carry out one ear picking operation. Ears (dried corn is one ear per plant), when harvesting fresh corn ears, the ear loss rate is large and the recovery rate is low. , The cleanliness of fresh corn ears is poor, which affects the subsequent operation procedures. In order to solve the above problems, a solution to remove impurities from fresh corn using a blower-type centrifugal fan has been developed, but there are many ...

Problems solved by technology

At present, the mechanized harvesting of fresh corn mostly uses traditional corn harvesting machines to carry out one ear picking operation. Ears (dried corn is one ear per plant), when harvesting fresh corn ears, the ear loss rate is large and the recovery rate is low. , the cleanliness of fresh corn ears is poor, which affects the subsequent operation procedures

In order to solve the above problems, a solution to remove impurities from fresh corn using a blower-type centrifugal fan has been developed, but there are many technical problems such as large space occupation, difficulty in configuration and installation, easy blockage in operation, poor crushing of debris and poor return to the field. solve
