Embodiment Construction
[0017] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0018] A specific embodiment of the impact crusher of the present invention, such as Figure 1 to Figure 2 As shown, the impact crusher includes a frame 1, the upper right side of the frame 1 is provided with a feed port 12, and the lower side is provided with a discharge port 13, the rotor 2 is located in the middle and lower part of the frame 1, and the axis of the rotor 2 is located at On the lower right side of the line connecting the feed port 12 and the discharge port 13, there are four blow bars 21 installed on the rotor 2, and there are four blow bars 21, which are evenly distributed along the axial direction of the rotor 2. The blow bars have a columnar structure, and the blow bars 21 One end of the rotor is fixed on the rotor 2, and the other end extends out of the rotor 2. The protruding end is the end of the hammering material. The rotor 2 ro...

The invention relates to a counterattack crusher. The counter-impact crusher comprises a rack, a rotor is arranged in the rack, plate hammers are arranged on the rotor, a distance-measuring sensor isarranged on the position, corresponding to a rotation plane of the plate hammers, on the rack, and the distance between the sensor and the plate hammers is monitored when the end faces of the plate hammers rotates to directly face the distance-measuring sensor; the length change of the plate hammers can be monitored in real time through arrangement of the distance-measuring sensor, and the lengthchange of the plate hammers is the wear amount of the plate hammers; when the wear amount reaches a certain value, if wear is continued, a rotor assembly can be damaged and the overhaul cost can be increased; when the length difference of the plate hammers is large because the difference of the wear amount of all the plate hammers is large, the particle size of the crusher can be uneven and produced raw materials can be unqualified. According to the monitoring value of the distance-measuring sensor, the plate hammers can be replaced in time when the wear amount of the plate hammers exceeds a set value, and the problems are prevented form appearing.
Description
technical field [0001] The invention relates to an impact crusher. Background technique [0002] Impact crusher, also known as impact crusher, is mainly used for metallurgy, chemical industry, building materials, hydropower and other materials processing that often need to be relocated, especially for the operation of mobile stones such as highways, railways, and hydropower projects. For example, the Chinese patent whose authorized notification number is CN204933566U discloses an impact crusher. The crusher includes a frame, which is surrounded by a front plate and other side plates. There is a rotor inside the frame, the rotor is equipped with a blow bar, and the frame is correspondingly equipped with an impact plate. During the use of the impact crusher, the blow bar on the rotor will gradually wear out as time increases, and The degree of wear of each blow bar is often different, so that the balance of the rotor cannot be guaranteed during the operation of the rotor, res...
