Straw cutting speed and length adjustable cylinder cutter

Abstract

The invention discloses a straw cutting speed and length adjustable cylinder cutter, belongs to the technical field of a straw resource utilization device, and is mainly used for rapidly and efficiently cutting a straw according to the required cutting length at the low power consumption. The cylinder cutter comprises a cylinder cutting device, a material pressing type feed device and a control display unit. The cylinder cutting device comprises a helical line type cutting moving blade, a horizontal cutting stationary blade and a rotating cylinder for installing the moving blade; the material pressing type feed device comprises an upper floating type material pressing roller, an upper fixing material pressing roller and a belt conveying platform; the cutting length is controlled through the belt conveying speed, and the cutting speed and the cutting efficiency are controlled through the belt conveying speed and the rotating speed of the rotating cylinder together. A controller acquires data through an acquisition test unit, the belt conveying speed and the rotating speed of the rotating cylinder are respectively controlled through calculation according to the set cutting length and the set cutting speed, and the straw is accurately efficiently cut at the low power consumption.

Description

technical field [0001] The invention belongs to the technical field of straw resource utilization devices, and relates to a straw cutter, in particular to a drum-type cutter with adjustable cutting speed and cutting length, which is mainly used for fast, efficient and low power consumption cutting of straw according to the required length cutting. Background technique [0002] The drum cutter adopts the rotary cutting method to cut the material into a certain length, which has the advantages of large feeding volume, high cutting efficiency, low power consumption, low cost, good length uniformity, and high degree of automation. Cutting straw with a drum cutter, compared with the traditional cutting method, if the cut straw is used as feed for ruminants, the palatability is better. If used as a cultivation substrate, it is conducive to full contact with the bacterial flora for fermentation and decomposition in the later stage, and also Fields are absorbed by plants. [0003]...

Problems solved by technology

This device can chop the material step by step according to the order of feeding, and it plays a role of crushing during the cutting process. However, the moving knife assembly of this device is too heavy, which increases the weight of the moving knife and affects the stability of the whole machine. High material and manufacturing costs, high power consumption, and poor throwing ability; patent CN201911075U discloses a rotary sawtooth moving knife drum-type mower device, which includes a frame, a power drive mechanism, a cylindrical cutting chamber and The feeding mechanism consists of a spiral knife holder fixed on the hubs at both ends by fastening screws, and there are slots on the outside of the spiral knife holder; insert the heads of a group of blades into the slots in sequence to form Helical combined blades are fixed by screws at both ends

Because the cutting tool is embedded by the cutting head, the cutting force is not uniform, and the operation stability is not high. The special cutting tool is not conducive to replacement. The feeding mechanism only has upper and lower pressure rollers, no power conveying, and the cutting length needs to be manually determined by the knife. Head and speed to adjust the feeding speed, the feeding port is easy to block, the degree of automation is low, and the labor intensity is high
