Anti-blocking device of crusher

Abstract

One or more embodiments of the invention provide an anti-blocking device of a crusher. The anti-blocking device of the crusher comprises a crushing cavity, wherein the crushing cavity is formed in a machine body; a feeding port is formed in the top end of the crushing cavity; a main shaft is driven by a driving mechanism to rotate so as to drive a disc to axially rotate; a plurality of hammers are uniformly fixed at intervals along the periphery of the side wall of the disc so as to rotate along with the disc to crush materials; materials in line with the crushing size are screened through sieve holes in the bottom wall of the crushing cavity so as to be discharged in time through a discharging cavity below the crushing cavity; meanwhile, a material leaking cavity is formed in one side of the lower end of the crushing cavity; a material leaking opening is formed in the side, close to the material leaking cavity, of the crushing cavity; a material leaking mechanism is arranged at the material leaking opening; when the materials accumulated at the material leaking opening during crushing reaches a limit value, the material leaking mechanism is automatically triggered to enable the material leaking opening to open, so that the leaked materials are distributed through the material leaking cavity; and the material leaking mechanism is automatically delayed and reset, so that the material leaking opening is closed again, and the automatic and efficient material blockage prevention function is realized.

Description

technical field [0001] One or more embodiments of this specification relate to the field of crusher equipment, in particular to a crusher anti-blocking device. Background technique [0002] During the daily production process of the crusher, if the feeding material flow is too large, or the material cannot be discharged in time after crushing, it will accumulate in the inner cavity of the crusher, causing the crusher to block the material. When the crusher is blocked, the workers need to spend It takes a lot of time to clean up, which increases the labor intensity of workers and increases the failure rate of the equipment, thus affecting the crushing production efficiency and the service life of the crusher equipment. For this, in the prior art, the crushing power of the crusher is often increased or Add additional crushing and discharging channels, but considering that blockages occur occasionally in the production process, but it is not a high-probability event, so increas...

Problems solved by technology

[0002] During the daily production process of the crusher, if the feeding material flow is too large, or the material cannot be discharged in time after crushing, it will accumulate in the inner cavity of the crusher, causing the crusher to block the material. When the crusher is blocked, the workers need to spend It takes a lot of time to clean up, which increases the labor intensity of workers and increases the failure rate of the equipment, thus affecting the crushing production efficiency and the service life of the crusher equipment. For this, in the prior art, the crushing power of the crusher is often increased or Add additional crushing and discharging channels, but considering that blockages occur occasionally in the production process, but it is not a high-probability event, so increasing the crushing power or crushing channels will obviously increase the cost of crusher equipment and reduce energy consumption. increase, thus, is not enough to meet the practical needs of better
