Description

Technical Field

[0001] This utility model relates to the field of lubrication device technology, specifically an improved lubrication device for a jaw crusher. Background Technology

[0002] Jaw crushers are driven by an electric motor, belt, and pulley. The eccentric shaft causes the moving jaw to move up and down. When the moving jaw rises, the angle between the toggle plate and the moving jaw increases, which pushes the moving jaw plate closer to the fixed jaw plate. At the same time, the material is crushed or split, achieving the purpose of crushing.

[0003] The lubrication device for a jaw crusher disclosed in patent document CN216590992U injects lubricant into the jaw plates and bearings by setting an oil pump, oil tank and distributor on the crusher body. The lubricant injection can be controlled by controlling the oil pump, which is more convenient, reduces the labor intensity of operators, reduces safety hazards, and has the characteristics of safety, labor saving, simplicity and high efficiency.

[0004] The above-mentioned technical solution has a matching structure between the lubrication device and the jaw crusher, which can only be used on one type of jaw crusher. It cannot be installed and used on jaw crushers of different specifications, resulting in limited use. In addition, manual addition of lubricating oil is required during use, which is not only troublesome to operate but also prone to safety accidents. Furthermore, the oil pipes are exposed and cannot be adjusted, which can easily affect the performance or cause damage or leakage due to external forces. Utility Model Content

[0005] The purpose of this invention is to provide an improved lubrication device for jaw crushers, in order to solve the limitations of existing lubrication devices and the technical problems of complex lubrication and adjustment.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0012] As a further embodiment of this invention, a sealing block and an oil-blocking plate are provided on the top side of the sealing plate. The oil-blocking plate has an arc-shaped structure, and a total of two oil-blocking plates are provided. Electric push rods are provided between the two ends of the sealing plate and the supply seat. The size and shape of the sealing block are matched with the supply pipe. Under the action of the liquid level sensor, when the lubricating oil decreases, the electric push rod pushes the sealing plate to move, causing the sealing block to move away from the supply pipe, thereby automatically replenishing the lubricating oil. Moreover, the oil-blocking plate prevents lubricating oil from leaking out of the supply seat and causing waste. Automatic replenishment reduces the difficulty of operation and improves the convenience of use.

[0013] As a further preferred embodiment of this utility model, the pipeline between the oil pump and the distributor is located outside the take-up roller, and a magnet is fixedly installed on the bottom side of the distributor.

The installation is convenient and quick, and it can be connected to jaw crushers of different specifications according to needs.

[0016] 2. In the lubrication process, this utility model connects and fixes the lubricating oil cylinder through threads and threaded holes, facilitating quick and easy replacement of the lubricating oil cylinder, reducing the difficulty of replenishment and safety risks. Subsequently, the oil pump is started to deliver the lubricating oil inside the storage cylinder to the oil nozzle for lubrication of the jaw crusher. Since a liquid level sensor is installed inside the storage cylinder, when the lubricating oil decreases, the electric push rod pushes the sealing plate to move, causing the sealing block to move away from the replenishment pipe, thereby automatically replenishing the lubricating oil. Moreover, the oil blocking plate prevents lubricating oil from leaking out of the replenishment seat and causing waste. Automatic replenishment reduces the difficulty of operation and improves the convenience of use. Attached Figure Description

[0027] See Figure 1-5 As shown, the improved jaw crusher lubrication device of this utility model includes a mounting base 1, an adjusting cylinder 2 is provided on the bottom side of the mounting base 1, an adjusting plate 3 is fixedly installed on the driving end of the adjusting cylinder 2, a supply seat 4 is installed on the right side of the adjusting plate 3 by bolts, a storage cylinder 5 is fixedly installed on the bottom side of the supply seat 4, a sealing plate 6 is provided on the inner side of the supply seat 4, an oil pump 7 is connected to the rear side of the storage cylinder 5 by a pipe, a distributor 8 is connected to the oil pump 7 by a pipe, and a lubricating oil cylinder 9 is threadedly connected to the top side of the supply seat 4.

[0028] Four lugs 101 are fixedly installed on the right side of the mounting base 1, located at the four corners of the right side of the mounting base 1. Two limit holes 102 are provided on the top side of the left end of the mounting base 1. The lugs 101 are connected and fixed to the designated position on the jaw crusher by passing bolts through them. Then, as needed, the adjusting cylinder 2 is activated to push the adjusting plate 3 for height adjustment. Simultaneously, the limit holes 102, in conjunction with the bottom limit rod, improve the stability of the movement of the adjusting plate 3.

[0029] A support plate 301 is fixedly installed on the rear side of the adjusting plate 3. Baffles 302 are fixedly installed at both ends of the rear side of the support plate 301. A winding roller 303 is movably installed between the baffles 302 via bearings. A torque spring is provided between the winding roller 303 and the baffles 302. The winding roller 303 and the torque spring facilitate the winding of the pipe when the distributor 8 is pulled for installation and adjustment, thus preventing the pipe from becoming too long during use, which could affect the performance, cause damage under external force, or lead to lubricating oil leakage.

[0030] The top side of the supply seat 4 has a threaded hole 401, and the inner side of the threaded hole 401 is connected to the lubricating oil cylinder 9 by a thread. The top side of the inner side of the supply seat 4 is provided with a supply pipe 402, and the outer side of the supply seat 4 has a through groove. The inner side of the storage cylinder 5 is provided with a liquid level sensor. By connecting and fixing the lubricating oil cylinder 9 to the threaded hole 401 by a thread, it is convenient to quickly replace the lubricating oil cylinder 9, reducing the difficulty of supplying and safety risks. Since the liquid level sensor is provided on the inner side of the storage cylinder 5, it is convenient to detect the lubricating oil, thus facilitating timely supply.

[0031] The top side of the sealing plate 6 is provided with a sealing block 601 and an oil-blocking plate 602. The oil-blocking plate 602 has an arc-shaped structure, and there are two oil-blocking plates 602 in total. Electric push rods 603 are provided between the two ends of the sealing plate 6 and the supply seat 4. The size and shape of the sealing block 601 match the supply pipe 402. Since a liquid level sensor is provided inside the storage cylinder 5, when the lubricating oil decreases, the electric push rod 603 pushes the sealing plate 6 to move, so that the sealing block 601 moves away from the supply pipe 402, thereby automatically replenishing the lubricating oil.

As needed, the adjusting cylinder 2 is activated to push the adjusting plate 3 up and down. After adjusting to the appropriate position, the distributor 8 is pulled to adhere and fix to the designated position on the jaw crusher. Under the action of the torque spring and the winding roller 303, the pipe is easily wound up, preventing excessive pipe length from affecting the use of the jaw crusher or being easily damaged by external forces and causing leakage. Then, the oil nozzle 803 is connected to the oil inlet end of the jaw crusher. The telescopic hose 802 facilitates retraction and adjustment. Installation is convenient and quick, and it can be connected to jaw crushers of different specifications according to requirements. In use, during lubrication, the lubricating oil cylinder 9 is connected and fixed by threads to the threaded hole 401, which facilitates quick replacement of the lubricating oil cylinder 9, reduces the difficulty of replenishment and safety risks. The oil pump 7 is started to deliver the lubricating oil inside the storage cylinder 5 to the oil nozzle 803 to lubricate the jaw crusher. Since a liquid level sensor is installed inside the storage cylinder 5, when the lubricating oil decreases, the electric push rod 603 pushes the sealing plate 6 to move, so that the sealing block 601 moves away from the replenishment pipe 402, thereby automatically replenishing the lubricating oil. Moreover, under the action of the oil blocking plate 602, the lubricating oil is prevented from leaking out of the replenishment seat 4 and causing waste. Automatic replenishment reduces the difficulty of operation and improves the convenience of use.
