Abstract

The utility model discloses a material grinding machine, which solves the problems of low cropping efficiency, long cropping time and much dust in the prior art, and motors are easily damaged. The material grinding machine comprises a frame and a cutter, wherein the cutter comprises a primary breaking knife, a stationary knife, a dynamic teeth cutter and a fixed teeth cutter, wherein the primary breaking knife is arranged on the frame of the primary breaking knife, the stationary knife is arranged on the frame and is matched with the primary breaking knife, the dynamic teeth knife is connectedwith the primary breaking knife through a gear in a driving way, the fixed teeth cutter is arranged on a rotatable fine tool holder and is matched with the dynamic teeth cuter, and the primary breaking knife is coaxially connected with a speed reduction motor. The material grinding machine has fast material cutting and is powerful through the matching work between a plurality rows of claw knifesand fixed knives and between the dynamic teeth cutter and the fixed teeth cutter, and has little dust and high efficiency.

Description

A kind of Material disintegrator

Technical field

The utility model relates to a kind of particle equipment, particularly a kind of Material disintegrator.

Background technology

Cutter structure in the existing particle equipment mainly is divided into two kinds; a kind of is the individual layer knife structure; the characteristics of this structure are for being equipped with serrated knife and rimmer knife (two sides, three or do not have the angle of throat tool) on an axle; there is the situation of cutting less than material when distributing blank far away because of rimmer knife in the shortcoming of this structure; the sharp inadequately situation that also can occur cutting motionless material and block machine of rimmer knife; regular meeting burns out motor; serrated knife is not cut for bigger material because of cutter tooth is short; blank efficient is low; the blank time is long and dust is many, shown in Fig. 1 a, Fig. 1 b.

Also have a kind of double-deck knife structure that is, second layer cutter also is a serrated knife, and the ground floor cutter is a kind of cutter that fractures of two row's structures.This cutter that fractures is bigger because of cutter does not have cutting edge (or being three swords or double knife-edge) and moving knife and stationary knife gap, adopts method that fractures rather than the method for cutting off during particle.The shortcoming of this structure is that the fracture structure of cutter can also meet the demands for fragile material, but for the stronger material of toughness frangibility not then, fracture often occurs rolling over not and blocks the situation that burns out motor, shown in Fig. 2 a, Fig. 2 b.

The utility model content

The purpose of this utility model is to disclose a kind of Material disintegrator, and blank efficient is low in the prior art, the blank time long to solve, dust is many, the problem that causes motor to damage easily.

A kind of Material disintegrator described in the utility model, comprise support and cutter, cutter comprises first broken cutter, stationary knife, moving serrated knife and decides serrated knife, first broken cutter is arranged on the first broken knife rest, stationary knife is arranged on the support and the adaptive installation of first broken cutter, moving serrated knife is in transmission connection by gear and first broken cutter, decides serrated knife and is arranged on the rotatable thin knife rest in the adaptive installation of moving serrated knife, and first broken cutter is connected with reducing motor is coaxial.

Wherein, first broken cutter is evenly distributed on same circumference by many rows pawl cutter, and every row is provided with multi-disc pawl cutter blade.

Material disintegrator of the present utility model, match with moving serrated knife by many rows pawl cutter, it is just broken to utilize the sharp pawl cutter of solid matter to carry out, and blank is strong and powerful, prevent that blank is not in place, moving serrated knife will can produce less dust and be broken into the homogeneous granules material fast through first broken particle.

The specific embodiment

Below in conjunction with accompanying drawing, a specific embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subjected to the restriction of the specific embodiment.

As shown in Figure 3-Figure 5, a kind of Material disintegrator of the utility model comprises support and cutter, cutter is double-deck particle structure, ground floor is the first broken cutter 1 that is arranged on the first broken knife rest 10, with the material preparatory processing, be broken into the segment material, the segment material is fallen into the moving serrated knife 12 of the second layer, is broken into particulate material by moving serrated knife 12 according to its size.Because this Material disintegrator does not have mesh structure, by moving serrated knife 12 decision chaff size, the particle dust is few, specifically as shown in Figure 8.

The first broken cutter 1 of ground floor has multi-disc pawl cutter blade 11 by many rows pawl cutter (present embodiment is 3 rows) evenly arranged evenly on a circumference on every row, specifically can be referring to Fig. 6, shown in Figure 7.First broken cutter 1 rotates under the drive of reducing motor 4 with 4 coaxial connections of reducing motor, first broken cutter 1, with stationary knife 6 on the support near the time material cut off.Less through just broken material size, fall into following moving serrated knife 12, moving serrated knife 12 carries out transmission with the first broken cutter 1 of ground floor by bearing 2 and gear, moving serrated knife 12 rotates under gear-driven effect, in the rotation be arranged on thin knife rest 9 on the serrated knife 8 of deciding cooperate, material is cut into graininess, removes discharge but be arranged on the material particles that the discharge blade 7 on the discharge knife rest 13 of dead axle upset will move on the serrated knife 12.

Above-mentioned pawl cutter blade 11 is a single dege blade, has only sword blank on one side, be convenient to sharpening, and blade is sharp, as Fig. 6, shown in Figure 7.

Material disintegrator of the present utility model also comprises feed hopper, dust board 3 and Crusher Room, and Crusher Room designs for double wall, prevents that dust from entering bearing and damage.But thin knife rest 9 dead axles upset is decided serrated knife and for the cutter adjustment provides condition for installing, and easy cleaning Material disintegrator simultaneously specifically can be referring to Fig. 3, Fig. 4.

More than disclosed only be a specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection domain of the present utility model.
