Abstract

The utility model discloses a hanging type machine for chopping and returning of crop straws matched with the small-four-wheel tractor. It comprises a machine frame, a machine casing, a hanging frame, a variable transmission assembly, a cutting knife device and a supporting roller. A cross beam on the front part of the machine frame is provided with the hanging frame. And a main shaft of the cutting knife device is fixed to the beams of both sides by bearings. The circumference of the cylinder surface of the main shaft are uniformly distributed with Y-shaped cutting knives which are arranged for six rows, equal quantity, symmetry and stagger arrangement, and the rear-lower part of the machine frame is provided with the turnable supporting roller. The use of the machine tool has not only maneuverability, flexibility, convenience for operation, but also stable operation, safety and reliability.

Description

A kind of stalks crushing machine

The utility model relates to the crop straw that uses in a kind of farmland and cuts up and farmland returned machine.

Existing crop stalk cuts up and farmland returned machine, for the supporting towed stalks crushing machine of large sized tractor.It partly is made up of hitch frame, frame, casing, transmission gear shift assembly, straw cutter etc., power resources by the transmission gear shift assembly, make the work of straw cutting knife in tractor motive power output shaft, in the unit driving process,, shed in the field with the crop straw chopping.This kind stalks crushing machine make unit elongated, so mobility is poor owing to be trail-type; Because the cutting knife on the main shaft is horizontal nine row arrangement, thereby operationalize not steadily, cause work quality also unstable.

In view of the problem that prior art exists, the purpose of this utility model is that a kind of and small-sized dilatory supporting suspension type crop stalk of design cuts up and farmland returned machine.

Stalks crushing machine of the present utility model is made of frame, casing, hanger bracket, speed change drive assembly, cutter and backing roll.Frame is a frame-type, the periphery of frame is fixed thereon by the casing that sheet metal forms, fixing hanger bracket on the anterior crossbeam of frame, on the beam of frame dual-side, the preceding lower device of frame rotating backing roll to the main shaft of cutter by bearing fixing.Cutter is made of tubular spindle, bearing, cutting knife, bearing pin, one end of main shaft is equipped with belt pulley, be uniformly distributed along the circumference on the main shaft face of cylinder six rows, etc. quantity, the interconnected Y type cutting knife of symmetry, cutting knife is hinged with the bearing that is welded on the main shaft by bearing pin.

This stalks crushing machine is compared with existing facility, has the following advantages: 1. this machine is connected the employing suspension type with tractor, and unit goes slick, and is convenient to operation; 2. machine works is steady, and is safe and reliable; 3. changing cutter is the rotary blade device, can make rotovator and use, and reaches dual-use; 4. this machine not only is used for the mincing and returning to the field of general crop straw, is particularly useful for the mincing and returning to the field operation of cotton region cotton straw.

Below in conjunction with accompanying drawing the utility model is further described.
