Abstract

The utility model discloses a large-size crusher and belongs to the crushing machinery field. The large-size crusher comprises a support, a machine body, a rotary shaft, blades and a drive motor, wherein the machine body is installed on the support and is divided into an upper part and a lower part, the upper part of the machine body is in movable connection with one side of the lower part through a hinge, the upper part is provided with a feed inlet, the rotary shaft penetrates through the lower part transversely, and a discharge outlet is arranged in the bottom end. The large-size crusher is characterized in that the blades are arranged on the rotary shaft, the rotary shaft penetrates through the lower part of the machine body and is connected with a driving wheel and a driven wheel at two sides, the driving wheel is connected with the drive motor, a filter screen is arranged on the machine body below the rotary shaft and is used for filtering of materials or impurities which can not be crushed. The large-size crusher is simple in structure and reasonable in design. The upper part of the machine body can be opened for examination of blocking or failure problems in the machine body. According to the large-size crusher, materials are crushed by centrifugal force produced when the blades in a shape of the Arabic numeral 7 are rotating at high speed. The materials and the impurities likely appearing in a crushing process which can not be crushed are filtered through mesh holes in the bottom of the machine body, so abrasion of the blades and damage to the crusher caused by long-time existing of the materials and the impurities in the machine body are avoided.

Description

a large crusher

technical field

The utility model relates to the technical field of crushing machinery, in particular to a large crusher. the

Background technique

Crusher, as the name suggests, is a machine that breaks large-sized solid raw materials into small-sized ones. At present, crushers are used in various industries, and there are many types. They are also used in the garbage recycling industry. There are a lot of plastic waste in the existing garbage recycling. Due to its large size, the first thing to do when recycling is to crush. The existing crusher is generally composed of a body, a rotating shaft, a rotating blade and a driving motor. On the rotating shaft, the rotating blades are all arranged in parallel. The rotating shaft runs through the body and connects with the driving wheel and the driven wheel on both sides respectively. The upper part of the body is provided with a material inlet, and the bottom is provided with a material outlet. It is the high-speed movement of the rotating blade on the rotating shaft. During the movement, the plastic waste thrown into the body is crushed. Because the size of the waste is too large, the existing small crusher cannot meet the operation requirements, and some materials cannot be crushed during the crushing process. , If such materials stay in the crusher for a long time, it will not only cause wear to the blades of the crusher, but may also damage the crusher. the

Utility model content

The technical problem to be solved by the utility model is to provide a large crusher with simple structure and reasonable design.

The technical problem to be solved by the utility model adopts the following technical solutions to realize:

A large-scale crusher, including a bracket, a body, a rotating shaft, a blade, and a driving motor. The body is installed on the bracket. The body is divided into an upper part and a lower part. The upper part and the lower part of the body are flexibly connected by hinges. There is a rotating shaft across the lower part, and the bottom end is provided with a discharge port. It is characterized in that: there is a blade on the rotating shaft, the rotating shaft runs through the lower body and is connected with the driving wheel and the driven wheel on both sides respectively, and the driving wheel is connected with the driving motor. , the body below the rotating shaft is provided with a filter screen to filter out unbreakable materials or impurities. the

The blades are spirally arranged on the rotating shaft from low to high. the

The blade is arranged in a 7-shaped shape. the

The beneficial effects of the utility model are: the utility model is simple in structure and reasonable in design, and the upper part of the body can be opened to check whether there is a blockage or a reverse failure in the body. Centrifugal force crushes the material. During the crushing process, there may be some unbreakable materials and impurities, which are filtered out through the mesh at the bottom of the machine body to prevent them from wearing the blade and damaging the crusher for a long time. the
