Abstract

The utility model relates to a material crushing device, in particular to a straw grinder which has a frame which is provided with a motor, and the motor is connected with a main shaft. A plurality of rotor knives is symmetrically arranged on the main shaft in two groups. A stationary knife bracket is arranged on the frame and provided with a plurality of stationary knives. The processing angle of the rotor knives and the stationary knives ranges from 8 to 12 DEG. The utility model has the advantages of simple structure, convenient repair, adjustable rotor knives, grass powder processing, high efficiency, long service life of the knives, etc.

Description

Stalk crasher

Technical field:

The utility model relates to material-pulverizing device, is a kind of stalk crasher.

Background technology:

Existing straw millstone is found to have more deficiency through using: main shaft rotates has only twice processing machine meeting a week, inefficiency, the chopping machining angle of moving knife is 0 degree, energy consumption is big, can not process harder stalk etc., the service life of cutter is short, because stationary knife can not be regulated, the length of processing stalk and herbage can not be regulated, and can not process grass meal; This machine noise is big; Complex structure, maintenance is inconvenient; Need many people's operations etc.

Summary of the invention:

The purpose of this utility model is, a kind of stalk crasher is provided, and make it have following advantage: simple in structure, easy to maintenance, stationary knife can be regulated, and can process grass meal, advantages such as operating efficiency height.

The utility model is in order to solve the existing in prior technology problem, adopt following scheme to solve, it has support body, motor is installed on the support body, and motor is connected with main shaft, and moving knife is installed on the main shaft, moving knife divides two groups of symmetric arrays to be installed on the main shaft, tool fixing frame is installed on the support body, stationary knife is installed on the tool fixing frame, the machining angle between stationary knife and the moving knife is the 8-12 degree.Machining angle between stationary knife and the moving knife is 10 degree.Setting angle between two groups of stationary knifes is 45 degree.Tool fixing frame is connected with the right gear case with the left gear case respectively by gear, and handle is connected with the right gear case, between left gear case and the right gear case connecting rod is installed.

The utility model has the advantages that: simple in structure, easy to maintenance, stationary knife can be regulated, and can process grass meal, high efficiency, advantage such as cutter life is long.

Description of drawings:

Fig. 1 is a structural representation of the present utility model, and accompanying drawing 2 is that A-A cuts open and shows the structure enlarged diagram in the accompanying drawing 1.

Embodiment:

16 is support bodys among the figure, motor 15 is installed on the support body 16, motor 15 is connected with main shaft 10, moving knife 28 is installed on the

main shaft

10,28 fens two groups of symmetric arrays of moving knife are installed on the main shaft 10, tool fixing frame 18 is installed on the support body 16, stationary knife (31) is installed on the tool fixing frame 18, the machining angle between stationary knife 31 and the moving knife 28 is the 8-12 degree.Machining angle between stationary knife 31 and the moving knife 28 is 10 degree.Setting angle between two groups of stationary knifes 31 is 45 degree.Tool fixing frame 18 is connected with right gear case 21 with left gear case 17 respectively by gear, and handle 23 is connected with right gear case 21, and connecting rod 19 is installed between left gear case 17 and the right gear case 21.The utility model can be regulated stationary knife group, support body, cabinet, blower fan and electrical equipment etc. from overall structure by movable cutter set, two-stage pectination and partly form.Wherein the symmetry of movable cutter set is installed, can reduce because the resonance that rotary speed unstabilization causes surely, reduce noise, improve safety, and produce the chance that main shaft rotates 8 processing a week, increase substantially operating efficiency, tool fixing frame 18 described in the utility model, be divided into former and later two knife rests, pressure knife block 20 is installed on stationary knife 31.The machining angle of present embodiment is designed to 10 degree, and the chopping processing of this machining angle not only reduces energy consumption, and can process and pulverize harder stalk or the bale of herbage, can prolong the service life of cutter.The utility model is used for crushed stalk, also can add grass meal, when adopting dry straw or hay processing grass meal, change upper plate 32 into gong at the bottom of, fan assembly is installed and fixed, start this machine and get final product.When being used for crushed stalk, will change base plate 32 at the bottom of the gong into again, remove fan assembly and get final product.It can be dry straw or bright stalk that the utility model adds stalk.Among the present embodiment figure 1 is the grass meal outlet, the 2nd, and fan blade, the 3rd, bearing, the 4th, the back of the body is female, the 5th, big nut, the 6th, cover, the 7th, outer edge bearing, the 8th, interior edge bearing, the 9th, loam cake, the 11st, side plate, the 12nd, shaft joint, the 13rd, guard shield, the 14th, distribution box, the 15th, motor, the 22nd, block, the 24th, hopper, the 25th, virtual moving knife, the 26th, front card, the 27th, movable knife disc, moving knife 28 is installed on the main shaft 10 by movable knife disc 27, the 29th, back card/back board, the 30th, discharging opening, the 33rd, lower shoe.
