Embodiment 1

[0030] Basic as attached figure 1 Shown: Shredder, consisting of:

[0031] Frame, the frame is fixedly installed on the ground, the frame is surrounded by baffles, and the inner side of the baffle is provided with a sponge cushion;

[0032] Press plate, the frame is provided with a slide rail for the press plate to slide up and down, and a hydraulic press is fixed above the press plate, and the hydraulic press drives the press plate to rise or fall;

[0033] The bottom plate, the bottom plate is fixed on the ground, the bottom plate is fixedly connected with the frame, the bottom plate is located directly under the pressure plate, and the bottom plate is provided with connection holes;

[0034] Locating pin, the locating pin is located in the connection hole, the locating pin is slidingly connected with the bottom plate, the upper part of the locating pin is provided with a spherical crown, and the crown is wrapped with a rubber layer;

[0035] Cylinder, the cylinder is buri...

Embodiment 2

[0040] Compared with Example 1, the only difference is that there is a powder leakage hole on the bottom plate, and the powder leakage hole and the connecting hole are arranged at intervals, and a collection bin is arranged under the powder leakage hole, and the collection bin is buried under the bottom plate, and the inner wall of the collection bin A rubber layer is bonded, a screw is nailed on the rubber layer, a hair ball is tied with a rope on the screw, and the hair ball can swing freely on the rubber layer. During the initial crushing process, the frame and the ground will vibrate slightly, which will cause the hair ball to swing. During the swing process, the rubber layer will be charged, so that the rubber layer can absorb the powder falling from the powder leakage hole. of fine dust.

Embodiment 3

[0042] Compared with Embodiment 1, the only difference is that the infrared sensor is replaced by a pressure sensor. The pressure sensor is located on the movement track of the pressing plate, and the pressure sensor is fixed on the frame. The pressure sensor takes its own pressure as the basis for judgment, has a simple structure, is convenient to install, and is accurate in judgment.

Abstract

The invention belongs to the field of building equipment and particularly discloses a crushing device. The crushing device comprises a rack, a pressing plate, a bottom plate, positioning pins and air cylinders, wherein a formwork is fixedly mounted on the ground and baffles are arranged at the periphery of the rack; the pressing plate is in sliding connection with the rack; a hydraulic cylinder is fixedly arranged above the pressing plate; the hydraulic cylinder drives the pressing plate to ascend or descend; the bottom plate is fixed on the ground, is fixedly connected with the rack, is located just below the pressing plate, and is provided with connecting holes; the positioning pins are located in the connecting holes; the positioning pins are in sliding connection with the bottom plate; a sphere-crown-shaped crown head is arranged at the upper part of each positioning pin; the air cylinders are buried below the bottom plate; each positioning pin is connected with the corresponding air cylinder; the air cylinders are respectively used for driving the positioning pins to stretch out or retract back; connecting pipes, which are communicated with one another, are arranged among all the air cylinders; the connecting pipes are provided with pressure leaking pipes. Aiming at the technical problems that small stone blocks are easily splashed to injure people and large ores are difficult to fix in a primary crushing process, the invention provides the crushing device.

Description

technical field [0001] The invention relates to the field of construction equipment, in particular to a crushing device. Background technique [0002] Crusher is widely used in fine crushing and coarse grinding of metal and non-metal ores, cement, refractory materials and various metallurgical slags. [0003] Ordinary crushers will directly perform crushing operations in the crushing cavity. However, when encountering some large ores, the impact crushing method is usually used for preliminary crushing, and the large ore is initially crushed into several smaller ores that can enter the crushing cavity, and then the polar crushing operation is performed with a crusher. [0004] In the actual processing process, this preliminary crushing operation is actually very troublesome and dangerous. During the initial crushing process, small stones often splash and hurt people. And in the process of primary crushing, large ore is also easy to move, which increases the difficulty of p...
