AI Technical Summary
The edges of the turntable and the outer side of the shaft of existing crushers are prone to wear, which increases the operating cost.
It adopts a T-shaped hammer and protective disc structure. The hammer head of the T-shaped hammer covers the edge of the turntable, and the protective disc covers the outside of the rotating shaft. Alloy materials are used to enhance wear resistance.
This reduces wear on the turntable and shaft, lowers the frequency of maintenance and replacement, and saves on operating costs.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to a building material processing equipment, in particular to a crusher capable of enhancing wear resistance. BACKGROUND
[0002] Crushers have been widely used in the processing of stone materials in the fields of metallurgy, chemical industry, building materials, water and electricity, etc.
[0003] The crusher is provided with a breaking hammer, which is generally arranged between two rotating discs, and the rotating discs are fixed on the rotating shaft through a pin shaft, and the rotating shaft rotates to drive the breaking hammer to work to break the stone materials.
[0004] The breaking hammer of the prior art is a cuboid, which is fixed between the two rotating discs, and the edge of the rotating disc is exposed on both sides of the hammer head of the breaking hammer, and in the process of breaking work, the edge of the rotating disc will collide with the stone materials to cause wear, which needs to be replaced frequently, thereby increasing the use cost.
[0005] In addition, in the process of breaking work, the outer side of the rotating wheel at both ends of the rotating shaft is also more likely to collide with the stone materials to cause wear, which needs to be replaced frequently, thereby increasing the use cost. TECHNICAL PROBLEM
[0006] The technical problem to be solved by the utility model is to provide a crusher capable of enhancing wear resistance to overcome the defects of the prior art.
[0007] In order to solve the above technical problem, the crusher capable of enhancing wear resistance of the utility model comprises a T-shaped hammer fixed on the rotating disc, the T-shaped hammer comprises a hammer head and a hammer rod, the hammer rod is fixed between the two rotating discs through bolts, the length of the hammer head is greater than the sum of the thickness and the distance between the two rotating discs, and the rotating disc is fixed on the rotating shaft through a pin shaft.
[0008] The outer side of the rotating wheel at both ends of the rotating shaft is fixedly connected with a protection disc.
[0009] The protection disc is composed of four fan-shaped blocks and is fixed on the outer side of the rotating wheel through bolts.
[0010] The protection disc is made of alloy material.
[0011] The rotating shaft is further provided with a protective sleeve, and the protective sleeve is fixed on the rotating shaft through a pin shaft.
[0012] The protection sleeve is fixed between the rotating discs.
[0013] The utility model discloses a structure, because the breaking hammer adopts T-shaped hammer, including hammer head and hammer pole, the hammer pole is fixed between two turntables through bolt, the length of hammer head is greater than the sum of the thickness of two turntables and its interval, the edge of turntable is covered by hammer head, and in the breaking work process, the hammer head contacts with stone, and the edge of turntable does not collide with stone and produce abrasion, thereby saving the use cost.
[0014] In addition, the protection disc is fixedly connected to the outer side of the rotating wheel at both ends of the rotating shaft, and the rotating shaft is further provided with a protective sleeve, so that the outer side of the rotating wheel at both ends of the rotating shaft also does not collide with stone and produce abrasion in the breaking work process, thereby saving the use cost. BRIEF DESCRIPTION OF DRAWINGS
[0015] Figure 1 It is the structural schematic diagram of the utility model. DETAILED DESCRIPTION
[0016] The utility model will be described in detail in combination with the drawings and specific embodiment:
[0017] As Figure 1 Indicated, the utility model discloses a breaking machine that can enhance wear -resisting function, including fixed in the T-shaped hammer 1 of turnplate 2.
[0018] T-shaped hammer includes hammer head and hammer pole, and the hammer pole is fixed between two turntables through bolt, and the length of hammer head is greater than the sum of the thickness of two turntables and its interval.
[0019] The turntable is fixed on the rotating shaft 5 through the pin shaft.
[0020] The rotating wheel outer side of the rotating shaft at both ends is fixedly connected with the protection disc 3.
[0021] The protection disc is spliced by four sector blocks and is fixed on the outer side of the rotating wheel through bolt.
[0022] The protection disc is made of alloy material.
[0023] The rotating shaft is further provided with the protective sleeve 4, and the protective sleeve is fixed on the rotating shaft through the pin shaft.
[0024] The protective sleeve is fixed between the turntables.
