Description

Technical Field

[0001] This utility model relates to the field of jaw crushers, specifically a belt cover for a jaw crusher. Background Technology

[0002] Jaw crushers, also known as jaw breakers or tiger's mouth crushers, consist of two jaw plates, a moving jaw and a stationary jaw, forming a crushing chamber. They simulate the movement of an animal's jaws to crush materials. The crusher is mainly driven by a motor that rotates the output shaft, which in turn rotates the small pulley. This pulley, in turn, rotates the large pulley via a belt, causing the eccentric shaft to rotate. This, in turn, causes the moving jaw to swing, thus achieving crushing. During the crushing process, crushed stone may splash onto the belt. As the belt rotates, it may come into contact with the crushed stone, causing the belt to wear faster and reducing its lifespan, which in turn affects the overall lifespan of the jaw crusher. Utility Model Content

[0003] The purpose of this utility model is to provide a belt cover for a jaw crusher to overcome the above-mentioned defects in the prior art.

[0004] According to the present invention, a belt cover for a jaw crusher includes an upper cover and a lower cover, which are symmetrically arranged. The upper cover is detachably connected to the lower cover. The upper cover includes an upper guard plate and an upper cover plate fixed to the upper edge of the upper guard plate. The lower cover includes a lower guard plate and a lower cover plate fixed to the lower edge of the lower guard plate. Two grooves are provided on the lower guard plate and the positioning port. The grooves are respectively fitted onto the eccentric shaft of the jaw crusher and the output shaft of the motor. The upper guard plate and the lower guard plate are both located between the belt and the casing of the jaw crusher.

[0005] With the above technical solution, the lower half cover is fixed to the casing of the jaw crusher, and the upper half cover is fixed to the lower half cover, thereby covering the pulley of the jaw crusher and preventing the crushed stone from splashing onto the belt and causing severe belt wear.

[0006] Preferably, the surfaces of the upper and lower half-covers that abut against each other coincide with the axis of the eccentric shaft and the axis of the motor output shaft.

[0007] The above technical solution ensures that the pulley can be exposed to a sufficiently large extent during the separation of the upper half of the cover without affecting the separation of the upper half of the cover.

[0008] Preferably, both ends of the upper cover plate are fixed with upper fixing plates, and both ends of the lower cover plate are fixed with lower fixing plates. The upper fixing plates and the lower fixing plates abut against each other, and the upper fixing plates and the lower fixing plates are detachably connected by a quick-release assembly.

[0009] The above technical solution increases the connection stability between the upper and lower half-covers by setting up the upper and lower fixing plates.

[0010] Preferably, the quick-release assembly includes a limiting block, a guide rod, and a locking block. The guide rod is fixed to the limiting block, and the locking block is slidably connected to the guide rod. A positioning block is fixed on the upper surface of the lower fixing plate, and a positioning opening is provided on the upper fixing plate. The positioning block can be fitted into the positioning opening. The positioning opening is set at one end away from the upper cover plate. A through groove is provided in the positioning block, and a central shaft is fixed between the front and rear side walls of the through groove. The limiting block is rotatably disposed in the through groove. The central shaft passes through the limiting block and is rotatably connected to the limiting block. A locking groove is provided on the side of the positioning block away from the upper cover plate. When the limiting block rotates to be parallel to and abuts against the upper fixing plate, the guide rod is parallel to the upper fixing plate, and the limiting block is locked into the locking groove.

[0011] The above technical solution, with its quick-release components, increases the ease of disassembly and assembly of the upper cover, thus facilitating belt replacement and maintenance.

[0012] Preferably, a spring seat is fixed at the end of the guide rod away from the limiting block, and a spring is fixed between the spring seat and the locking block.

[0013] The above technical solution, with the spring setting, increases the stability of the card block when it is inserted into the card slot.

[0014] Preferably, the upper and lower end faces of the card block are each fixed with a protrusion located between the two through slots, and the protrusion is higher than the upper and lower sides of the limiting block.

[0015] The above technical solution makes it easier to detach the card block from the card slot.

[0016] The beneficial effects of this utility model are: the lower half cover is fixed on the casing of the jaw crusher, and the upper half cover is fixed on the lower half cover, thereby covering the pulley of the jaw crusher, thus preventing the crushed stone from splashing onto the belt and causing severe belt wear. The design of the disassembly component increases the ease of disassembly and assembly of the upper half cover, thereby facilitating the replacement and maintenance of the belt.
