Conditioning equipment for selectively harvesting corn stalk

Abstract

The invention provides a dedicated maize straw selecting and harvesting conditioner. The whole machine comprises a header, a flattening device, a shredding device, a flattening straw conveying device, a root stubble breaking device, a flattening straw guide valve, a shredded straw flow valve and a self-propelled chassis. The header is connected with the inclined conveying device, and the upper shaft of the inclined conveying device is hinged to a frame. The header can swing around the upper shaft of the inclined conveying device so as to harvest different parts of the straw. The upper roller of a feeding roller and the upper rollers of flattening rollers are limited to float up and down by a guide slot spring, so that flattening rollers rotate oppositely to mill the straw. The front end of the flattening straw guide valve is hinged to the frame and can be swung to be regulated in position so as to guide the straw. When the flattening straw guide valve is shifted to an upper position, the flattening straw conveying device is revolved and an elastic plate type compressing wheel performs the rotating compression so as to deliver the flattened straw out of the machine to be dried in a strip shape for the preparation of briquetted compressed dry feed or briquetted fuel. When the flattening straw guide valve is shifted to a lower position, the shredding device is rotated at a high speed for shredding and polishing the straw. Shredded stalks flow toward a shell hinged to the upper end of the shredding device. The shredded straw flow valve opens or closes to send the crushed straw to be ensiled or returned. The front end of the support of the root stubble breaking device is hinged to the frame. A toddy roller arranged at the tail end of the support is contacted with the ground to cope the ground. A pressure spring is arranged between the tail part of the support and the frame and is used for realizing the adjustment of the downward pressure of a root system breaking knife roller.

Description

technical field [0001] The invention relates to a corn stalk harvesting and processing combined operation machine, in particular to a corn stalk selective harvesting and processing modulation machine in which the straw harvesting and processing part and the use of the straw can be selected on demand and multi-functional devices can be switched on demand. Background technique [0002] Corn harvesting includes harvesting ears and harvesting stalks. At present, the machinery suitable for corn harvesting mainly includes corn ear picking machine, corn ear picking and peeling straw grinder, corn ear picking silage machine and special straw crushing and returning machine. Returning to the field, or chopping and collecting silage with a silage machine, does not consider the selective harvesting and comprehensive processing and conversion of biomass with different physical and mechanical characteristics in different parts of the stalk when harvesting.
