Description

Technical Field

[0001] The utility model mainly relates to the technical field of gravel crushing, and particularly relates to a jaw crusher for gravel. Background Art

[0002] The jaw crusher is commonly known as the jaw breaker. It consists of a moving jaw device and a static jaw device to form a crushing cavity, and is a crusher that simulates the movement of the two jaws of an animal to complete the material crushing operation. It is widely used in industries such as mining, smelting, building materials, highways, railways, water conservancy, and chemical engineering.

[0003] The jaw crusher drives the crankshaft through a motor to complete the reciprocating movement of the moving jaw plate, and uses the extrusion between the moving jaw plate and the static jaw plate to complete the crushing of materials. However, the static jaw of the existing jaw crusher is generally directly fixedly installed on the frame, and the distance and angle between the moving jaw and the static jaw are inconvenient to adjust. Therefore, it is inconvenient to selectively crush to obtain larger or smaller gravel, and its use is not flexible enough. Therefore, it is necessary to propose an improvement measure to solve the above technical problems.

[0004] It should be noted that the above content belongs to the technical cognition scope of the inventor. Due to the vast and extremely complex technical content in this field, the above content of this application does not necessarily constitute the prior art. Content of the Utility Model

[0005] 1. Technical problems to be solved by the utility model:

[0006] The utility model provides a jaw crusher for gravel to solve the technical problems existing in the above background art.

[0007] 2. Technical solutions:

[0008] To achieve the above purpose, the technical solution provided by the utility model is: a jaw crusher for gravel, including a frame. On one side inside the frame, a moving jaw device is correspondingly arranged, and on the other side inside the frame, an adjustable static jaw device is correspondingly arranged; the static jaw device includes a mounting plate and a static jaw plate. The mounting plate is correspondingly installed on one side inside the frame and can be adjusted horizontally; on the inner end face of the mounting plate, a groove penetrating up and down is correspondingly opened. A connecting plate is correspondingly arranged in the groove. The two sides of the bottom of the connecting plate are rotatably connected to the two sides of the lower groove opening of the groove of the mounting plate. An adjusting mechanism is correspondingly arranged above the groove of the mounting plate. The upper part of the connecting plate realizes the adjustment of the rotation angle through the adjusting mechanism, and the static jaw plate is correspondingly installed on the inner end face of the connecting plate.

[0009] Furthermore, the adjusting mechanism includes a threaded rod. A threaded bushing is correspondingly installed at the middle position of the upper part of the groove of the mounting plate. The threaded rod is correspondingly installed in the threaded bushing in a threaded manner. A butterfly-shaped head is correspondingly provided at the outer end of the threaded rod. The inner end of the threaded rod abuts against the connecting plate correspondingly. A compression spring is correspondingly connected between the connecting plate and the bottom of the groove of the mounting plate.

[0010] Furthermore, there are four compression springs. The four compression springs are symmetrically distributed around the threaded rod. One end of the compression spring is connected to the connecting plate, and the other end of the compression spring is connected to the bottom of the groove of the mounting plate.

[0011] Furthermore, two U-shaped grooves are correspondingly opened on both side plates at one end of the frame close to the fixed jaw device. The two U-shaped grooves are distributed corresponding to each other up and down. A locking block is correspondingly provided outside the U-shaped groove. A locking bolt passes through the locking block. Two threaded holes are opened at the corresponding upper and lower positions on both sides of the mounting plate. After the locking bolt passes through the locking block and the U-shaped groove, it is correspondingly installed in the threaded hole on the side of the mounting plate. Tightening the locking bolt can realize the lateral fixation of the mounting plate.

[0012] 3. Beneficial effects:

[0013] Adopting the technical solution provided by the present invention, compared with the prior art, it has the following beneficial effects:

[0014] The present invention is reasonably designed. Through the setting of the U-shaped groove on the side of the frame and the cooperation of the locking bolt and the locking block, when in use, after adjusting the fixed jaw device to the appropriate position, the locking bolt can be tightened to make the locking block press the frame, so as to realize the limit fixation of the fixed jaw device, so that the distance between the fixed jaw device and the moving jaw device can be adjusted according to the use requirements, which is convenient for crushing gravel of different sizes. If the distance between the fixed jaw device and the moving jaw device is relatively close, the crushed gravel is smaller. If the distance between the fixed jaw device and the moving jaw device is relatively far, the crushed gravel is larger. In addition, the present invention also makes the upper deflection angle of the connecting plate and the fixed jaw plate thereon adjustable through the cooperation of the threaded rod and the compression spring, so as to better adapt to crushing gravel of different sizes. It is more flexible in use, its overall structure is ingeniously designed, it is flexible and convenient to use, and it has strong practicability.

[0015] It should be noted that since the structures not introduced in the present invention do not involve the design key points and improvement directions of the present invention, they are the same as the prior art or can be realized by using the prior art, and will not be elaborated here.
