Ring hammer crusher with rigid filter screen

Abstract

The invention relates to the technical field of crushing equipment, and discloses a ring hammer crusher with a rigid filter screen. The ring hammer crusher comprises a base, a crushing chamber is fixedly connected with the upper end of the base, and a feed inlet is fixedly connected with the upper end of the crushing chamber. By arranging a partial gear, a full-tooth gear, a pull rope and a pull rod, during crushing work, a motor works to drive a first rotating shaft to rotate, and particles are crushed; meanwhile, the partial gear is driven to rotate through a belt, and when the partial gear meshes with the full-tooth gear, a reel winds the pull rope, so that the pull rod overcomes elastic force of a second spring to drive a bracket to move downwards to store energy; when the full-tooth gear continues to rotate to the position where the full-tooth gear is not meshed with part of gears, the second spring rapidly rebounds under the action of the elasticity of the second spring to wind the reel; and meanwhile, the filter screen can rapidly move upwards, coarse grains accumulated on the upper surface of the filter screen are thrown up and get close to the ring hammer, the operation is repeated, secondary and even repeated crushing of coarse grains is facilitated, and the crushing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of crushing equipment, in particular to a ring hammer crusher with a rigid filter screen. Background technique [0002] The ring hammer crusher breaks the material through the collision of the high-speed rotating hammer body and the material. It has the characteristics of simple structure, large crushing ratio, and high production efficiency. It can be used for dry and wet crushing. The ring hammer crusher is suitable for mines, Cement, coal, metallurgy, building materials, roads, combustion and other departments carry out fine crushing of medium-hard and brittle materials. The main working part of the ring hammer crusher is the rotor with a hammer (also known as the hammer head). The rotor consists of a main shaft, a circular Composed of a disc and a hammer, the motor drives the rotor to rotate at high speed in the crushing cavity. The material is fed into the machine from the upper feeding port, and is cru...

Problems solved by technology

[0003] However, the existing ring hammer crusher still has the following deficiencies in the actual use process. Since the sieve plate is fixed at the lower part of the rotor, and the gap between the sieve plate and the rotor is small, it is convenient to continue to be hit and ground by the hammer. After the large-sized incompletely broken coarse grains fall onto the sieve plate, the coarse grains are easily stuck in the gap between the sieve plate and the hammer. Severe wear and tear will cause damage to the sieve plate, and even cause coarse particles to jam the crusher, causing damage to the motor; and when the sieve plate is set lower, the unbroken coarse particles will not be able to continue to be hit by the hammer and grinding, not only cannot be crushed, reducing the crushing efficiency, but also with the accumulation of coarse particles, it is easy to cause blockage of the sieve plate and affect the discharge effect
