Abstract

The utility model discloses a reversible hammer crusher, which comprises a shell, a hammer head rotor, a feeding chute and a baffle plate, wherein the shell is provided with a hammer head rotor; the upper part of the shell is provided with an opening, a crushing cavity is formed inside the shell, the hammer head rotor is arranged in the crushing cavity, and the feeding chute is arranged at the opening of the shell and used for feeding materials into the crushing cavity; the baffle shelters from the opening part at the casing and the fixed other end of one end is mobile, and when the baffle top bore material pressure, the mobilizable one end of baffle is opened to broken chamber direction, and when the baffle top does not bore pressure, the baffle resumes to shelter from the opening. This broken machine of reversible hammer sets up the baffle, when fuel falls to the baffle from the feeding chute, under the effect of gravity, can have the crowded baffle downstream of opening to guarantee that fuel smoothly gets into broken machine of hammer. Meanwhile, the baffle can shield the opening of the crushing cavity, and the feeding chute is separated to achieve a sealing effect, so that the purpose of dust suppression is achieved.

Description

Reversible hammer crusher

Technical Field

The utility model relates to crushing equipment, in particular to a reversible hammer crusher.

Background

In the sintering production process, the fuel is crushed by using a reversible hammer crusher. When the reversible hammer crusher operates, the rotor is driven by the motor, the rotor drives the hammer head on the rotor to rotate at a high speed, and fuel enters the crushing cavity and is crushed by the high-speed impact, impact and shearing of the hammer head.

However, when the hammer head rotates at a high speed, wind power is generated, and small-particle fuel is blown to emerge from the feeding chute, so that the field environment is severe and the material is scattered.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: in order to overcome the defects of the prior art, the utility model provides a reversible hammer crusher which can effectively avoid dust raising and material scattering from a feeding chute.

The technical scheme is as follows: the utility model relates to a reversible hammer crusher, which comprises a shell, a hammer head rotor, a feeding chute and a baffle plate, wherein the shell is provided with a hammer head rotor; the upper part of the shell is provided with an opening, a crushing cavity is formed inside the shell, the hammer head rotor is arranged in the crushing cavity, and the feeding chute is arranged at the opening of the shell and used for feeding materials into the crushing cavity; the baffle shelters from the opening part at the casing and the fixed other end of one end is mobile, and when the baffle top bore material pressure, the mobilizable one end of baffle is opened to broken chamber direction, and when the baffle top does not bore pressure, the baffle resumes to shelter from the opening.

Has the advantages that: compared with the prior art, the reversible hammer crusher is provided with the baffle, when fuel falls to the baffle from the feeding chute, the baffle can be extruded to move downwards under the action of gravity, and therefore the fuel can be guaranteed to smoothly enter the hammer crusher. Meanwhile, the baffle can shield the opening of the crushing cavity, and the feeding chute is separated to achieve a sealing effect, so that the purpose of dust suppression is achieved.

Drawings

Fig. 1 is a schematic structural view of the present invention.

Detailed Description

As shown in fig. 1, the main structure of the reversible hammer crusher is substantially the same as that of the existing equipment, and a crushing cavity with an upper opening is formed by the shell 1, the position and the angle of the specific opening are set according to actual requirements, the feeding chute 3 is installed at the opening and corresponds to the feeding belt 10, and the inclination angle of the blanking surface of the chute side plate 31 is also set according to actual requirements.

The hammer rotor 2 is arranged in the crushing cavity, so that materials sliding into the crushing cavity from the discharging surface can be crushed under the driving of a motor.

The key point of the utility model is that the opening of the shell 1 between the crushing cavity and the feeding chute 3 is sealed and shielded by a baffle 4. The fixed other end of one end of this baffle 4 is mobile, and when 4 tops of baffle born material pressure, mobilizable one end was opened to broken chamber direction and is put into the material, and when 4 tops of baffle did not bear pressure, baffle 4 recovered and sheltered from the opening.

In particular, the flap 4 may be implemented in various forms, such as a hinged door design that is restorable when turned down. In the embodiment, a simpler mode is adopted, that is, the baffle 4 is a flexible baffle and can be made of leather or other materials with certain toughness. The baffle 4 is larger than the opening size of the shell 1, one end of the baffle is fixed on the side wall of the shell 1, and the other end of the baffle is extruded and bent downwards to form an arc shape and is abutted against the opposite side wall. So that when the material falls on the baffle 4, the movable end can be squeezed open and fall to the crushing cavity. In order to facilitate the smooth falling of the materials, the movable end of the baffle 4 is arranged at the same side of the chute side plate 31, so that the materials can be directly extruded to open the baffle 4 and fall down.
