Description

Technical Field

[0001] The utility model relates to the technical field of jaw crushers, in particular to a jaw crusher which is convenient for replacing a jaw plate. Background Art

[0002] Jaw crusher is commonly known as jaw crusher, also known as tiger mouth. It consists of two jaw plates, movable jaw and static jaw, to form a crushing chamber. It simulates the movement of animal's two jaws to complete material crushing operations. Jaw crusher is widely used in some factories.

[0003] A jaw crusher is needed in the production of zeolite powder, but the existing jaw crusher is not convenient for replacing the jaw plate. Most of the existing jaw plates are fixed by screws, which are not convenient for disassembly after a long time of use, and the jaw plate needs certain protection during use. Therefore, it has become an urgent problem to be solved to improve and perfect the above problems.

[0004] At present, there is an existing jaw crusher that is easy to replace the jaw plate (such as announcement number: CN217699293U), which discloses a jaw crusher that is easy to replace the jaw plate, including a frame, a side guard plate is arranged on the back of the frame, a control panel is arranged on the surface of the frame, a rotating disk is arranged on one side of the surface of the frame, a belt is arranged on the surface of the rotating disk, and a motor body is arranged on the inner side wall of the belt; a stabilizing block, the stabilizing block is installed inside the side guard plate, the bottom end of the motor body is fixedly connected with a base frame, a mounting block is arranged inside the frame, and a first clamping plate is arranged on the upper end surface of the mounting block. The utility model fixes and installs it by multiple sets of fixing bolts, and the design of the first clamping plate and the second clamping plate can quickly install the movable jaw plate, and when replacing it later, it can be quickly replaced by screwing out the fixing bolts on the back of the mounting block and then clamping the movable jaw plate, which is easy to operate and convenient to install.

[0005] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems:

[0006] 1. The existing device fixes the movable jaw plate by setting the first clamping plate and the second clamping plate, which does achieve the purpose of facilitating the replacement of the jaw plate. However, the device needs to disassemble the entire movable jaw plate to replace the jaw plate, and it is impossible to replace the individual parts of the jaw plate that are severely worn or damaged. Therefore, there is room for improvement in the device. It is not easy to replace the severely worn or damaged parts of the jaw plate separately. Once the replacement is damaged, the entire jaw plate needs to be removed and replaced, which wastes time. In addition, because the movable jaw plate of the device is an integral whole, after a single part is damaged, the entire movable jaw plate needs to be replaced, which has the problem of high maintenance cost.

[0007] 2. The existing device is not provided with a replaceable structure for the fixed jaw plate, so the fixed jaw plate of the device has the problem of being difficult to replace. Utility Model Content

[0034] The mounting frame 3 has first through holes 302 at both upper and lower ends. The first through holes 302 are arranged in two rows, with six first through holes 302 in each row. There are twelve first through holes 302 in total.

[0035] The top surfaces of the inlay strips 601 on both sides of the movable jaw plate 6 are provided with second bolt holes 602, and six slots 603 are provided on the side of the movable jaw plate 6 away from the mounting frame 3. Two T-shaped through holes 605 are provided in each slot 603. There are twelve T-shaped through holes 605 in total. The twelve T-shaped through holes 605 are parallel to and aligned with the twelve first through holes 302. A No. 1 bolt 8 is jointly sleeved in the T-shaped through holes 605 and the first through holes 302. There are twelve No. 1 bolts 8 in total. The screw heads of the No. 1 bolts 8 are deeply embedded in the movable jaw plate 6, and the No. 1 bolts 8 do not protrude from the slots 603.

[0036] The bottom surface of the six slots 603 is also provided with limiting slots 604, the number of which is six. A clamping block 702 is clamped in the limiting slot 604, and the clamping block 702 is fixedly connected to the jaw plate tooth 7. A fixing slot 701 is provided at the end of the jaw plate tooth 7 away from the clamping block 702, and the number of the jaw plate teeth 7 is six.

[0037] A baffle plate 5 is installed on the top surface of the mounting frame 3 and the movable jaw plate 6. Through holes are opened at both ends of the baffle plate 5. The two through holes and the two second bolt holes 602 are perpendicular to each other. Two No. 2 bolts 9 are jointly sleeved on the two through holes and the two second bolt holes 602.

[0038] Six clamping bolts 501 are fixedly connected to the bottom surface of the baffle 5 , and the clamping bolts 501 are slidably clamped in the fixing grooves 701 formed on the top surfaces of the six jaw plate teeth 7 .

Often, the damage of the first replaceable jaw plate occurs at a certain position, and it is rather troublesome to disassemble the first replaceable jaw plate as a whole. It is only necessary to remove the baffle plate 5 and make the six clamping bolts 501 slide out of the fixing groove 701, so that the six jaw plate teeth 7 can be removed, and only the jaw plate teeth 7 at the damaged part need to be replaced, which saves the time for disassembling the first replaceable jaw plate as a whole. During maintenance, it is only necessary to replace the jaw plate teeth 7 at the damaged part, which saves cost and solves the problem that the existing device is not easy to replace the severely worn or damaged parts of the jaw plate separately, which wastes time and has high maintenance costs.

[0042] Working principle:

[0043] In the first step, after the first replaceable jaw plate is damaged after long-term use, the baffle plate 5 can be removed by removing the No. 2 bolts 9 at both ends of the baffle plate 5, and then the movable jaw plate 6 can be removed as a whole by removing the twelve No. 1 bolts 8. Often, the damage of the first replaceable jaw plate occurs at a certain position, and it is rather troublesome to disassemble the first replaceable jaw plate as a whole. Only the baffle plate 5 needs to be removed to make the six clamping bolts 501 slide out of the fixing grooves 701, so that the six jaw plate teeth 7 can be removed. Only the jaw plate teeth 7 at the damaged part need to be replaced, which saves the time for disassembling the first replaceable jaw plate as a whole. During maintenance, only the jaw plate teeth 7 at the damaged part need to be replaced, which saves the cost.

[0044] In the second step, when disassembling the second replaceable jaw plate, you only need to remove the four No. 2 bolts 9, then you can hold the pull groove 401 to lift the connecting plate 4 and the fixed jaw plate 402, and slide them out of the installation groove 101. At this time, the second replaceable jaw plate can be replaced with a new one as a whole.

[0045] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
