Description

a crushing machine

technical field

The utility model relates to crushing equipment, in particular to a crushing machine.

Background technique

The cutter structure in the existing crushing equipment is mainly divided into two types. One is the single-layer cutter structure. The disadvantage of the structure is that the long knife is distributed far away when cutting the material, and there is a situation that the material cannot be cut, and the long knife is not sharp enough, and the machine will not be able to cut the material, and the machine will often burn out. The toothed knife is short due to the short teeth. However, it cannot be cut for larger materials, the cutting efficiency is low, the cutting time is long and there is a lot of dust, as shown in Figure 1a and Figure 1b.

There is also a double-layer knife structure, the second-layer knife is also a toothed knife, and the first-layer knife is a breaking knife with a two-row structure. Because the broken knife has no cutting edge (or three-sided or double-sided knife) and the gap between the moving knife and the fixed knife is relatively large, the breaking method is used instead of the cutting method. The disadvantage of this structure is that the structure of the breaking knife can meet the requirements for brittle materials, but it is not easy to break for materials with strong toughness, and often occurs when the broken material is broken and the motor is stuck and burnt out, as shown in Figure 2a and Figure 2b .

Utility model content

The purpose of the utility model is to disclose a crushing machine to solve the problems in the prior art of low cutting efficiency, long cutting time, a lot of dust, and easy damage to the motor.

A crushing machine described in the utility model includes a machine base and a cutter. The cutter includes a primary crushing knife, a fixed knife, a movable tooth knife and a fixed tooth knife. The primary crushing knife is arranged on the primary crushing knife holder, and the fixed knife is arranged on the The base is fitted with the primary crushing knife, the movable toothed knife is connected to the primary crushing knife through the gear, the fixed toothed knife is set on the rotatable fine knife holder and fitted with the movable toothed knife, the primary crushing knife is connected with the gear motor shaft connection.

Among them, the primary crushing knives are evenly arranged on the same circumference by multiple rows of claw knives, and each row is provided with multiple claw knife blades.

The shredder of the utility model, through the cooperation of multiple rows of claw knives and movable tooth knives, uses densely arranged sharp claw knives for primary crushing. The crushed material can be quickly broken into uniform granules with less dust.

Detailed ways

A specific embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

As shown in Figures 3-5, a crushing machine of the present invention includes a machine base and a cutter, the cutter is a double-layer crushing structure, the first layer is the primary crushing knife 1 arranged on the primary crushing knife holder 10, and the The material is preliminarily processed and broken into small pieces. The small pieces fall into the second layer of movable tooth cutters 12, and the movable tooth cutters 12 are broken into granular materials according to their size. Because the crushing machine has no screen structure, the size of the crushed material is determined by the movable tooth cutter 12, and the crushed material has less dust, as shown in Figure 8.

The primary crushing knife 1 of the first layer is arranged evenly on a circumference by multiple rows of claw knives (3 rows in this embodiment), and there are many claw knife blades 11 on each row, as shown in Fig. 6 and Fig. 7 . The first crushing knife 1 is coaxially connected with the reduction motor 4, and the first crushing knife 1 rotates under the drive of the reduction motor 4, and cuts off the material when it is close to the fixed knife 6 on the support. The primary crushed material is small in size and falls into the movable tooth cutter 12 below. The movable tooth cutter 12 and the primary crushing knife 1 of the first layer are transmitted through the bearing 2 and the gear. The movable tooth cutter 12 rotates under the action of the gear transmission. During the rotation, it cooperates with the fixed tooth knife 8 arranged on the fine knife holder 9 to cut the material into granular shape, and the discharge blade 7 arranged on the discharge knife holder 13 which can be turned over by a fixed axis will cut the material on the movable tooth knife 12 Particles are removed and discharged.

Above-mentioned claw knife blade 11 is a single-edged blade, only has one edge to cut material, is convenient to sharpen, and the blade is sharp, as shown in Fig. 6, Fig. 7.

The crushing machine of the utility model also includes a feed hopper, a dust shield 3 and a crushing chamber, and the crushing chamber is designed with double walls to prevent dust from entering the bearing and damaging it. The thin knife rest 9 can be turned over on a fixed axis, which provides conditions for installing the fixed tooth knife and adjusting the knife, and facilitates the cleaning of the shredder, as shown in Fig. 3 and Fig. 4 for details.

What is disclosed above is only a specific embodiment of the utility model, but the utility model is not limited thereto, and any changes conceivable by those skilled in the art should fall within the protection scope of the utility model.
