Description

a hammer crusher

technical field

The utility model relates to a hammer crusher.

Background technique

At present, hammer crushers are widely used in cement, chemical, electric power, metallurgy, mining and other industries. The hammer crusher mainly relies on impact energy to complete the crushing operation of materials. When the hammer crusher is working, the motor drives the rotor to rotate at a high speed, and the material enters the crusher chamber evenly. The high-speed rotating hammer head rushes to the baffle plate and sieve bar in the frame, and the material larger than the sieve hole size is retained on the sieve plate and continues to be hit and ground by the hammer until it is crushed to the required discharge particle size, and finally passes through the sieve plate and is discharged from the machine. outside.

A hammer crusher is disclosed in Chinese patent application number: 201420530049.3, which includes a rotor disc, a hammer head, a semicircular grate plate, a feed port and a discharge port, and the output shaft of the motor drives the rotor mounted on the shaft through a pulley The hammer head has installation holes and is hinged on the rotor disk by a pin shaft. Its characteristics are: the semicircular grate plate is installed on the lower half of the crusher body, and the grate slit on the semicircular grate plate is designed It is the radial direction, and the length direction of the grate is parallel to the rotary surface of the hammer head. This technical solution is easy to block when discharging, and the technical solution has only one particle after the material is damaged. When different material particles are required, this technical solution is not suitable. This technical scheme needs to be further improved.

Utility model content

In view of the above problems, the utility model provides a hammer crusher, which is convenient for discharging materials and can also discharge materials with particles of different sizes as required.

In order to solve the above problems, the technical solution provided by the utility model is:

A hammer crusher, comprising a box body, the box body is provided with a feeding port, and also includes two hydraulic cylinders, the two hydraulic cylinders are placed outside the box body, and the side walls of the box body There are 2 gaps, the bottom of the box is provided with a first outlet, the box is provided with a first filter, and a first crushing mechanism is provided above the first filter; the first Both sides of the filter screen extend outwards through the gap and are connected to the output end of the hydraulic cylinder in transmission.

When the hammer crusher is working, the hydraulic cylinder drives the first filter screen to vibrate up and down, which facilitates the discharge of materials. The first filter screen is placed under the first crushing mechanism, and the self-weight of the material is used to facilitate the discharge of materials.

Preferably, a second filter is provided below the first filter, the aperture of the second filter is smaller than the aperture of the first filter, and a second filter is provided between the first and second filter. 2. Crushing mechanism.

The second filter screen and the second crushing mechanism are added to produce materials with smaller particle diameters, which can meet different needs and have good adaptability. It also avoids the stuffy car caused by the large instantaneous volume, and also reduces the wear of the parts of the crusher to a certain extent.

Preferably, a second outlet is provided on the side wall of the box between the first and second filter nets. Capable of producing materials with 2 different particle diameters.

Preferably, the second filter screen is oblique to the horizontal plane, and the second outlet is located at the lower end of the second filter screen. It is convenient for material discharge.

Preferably, a first conveyor belt is provided below the first discharge port, and a second conveyor belt is provided at the position of the second discharge port. It is convenient to transport the crushed materials away without stopping the machine, and the production efficiency is higher.

Compared with the prior art, the beneficial effects of the utility model are:

The utility model is convenient for discharging materials, can crush materials of different particle sizes according to needs, and is also convenient for transporting the crushed materials without stopping the machine, and has higher production efficiency, simple structure and practicality.
