Description

Technical Field

[0001] The utility model relates to the technical field of jaw crushers, in particular to a protective base for jaw crushers. Background Art

[0002] The protective base of the jaw crusher is an important part of the jaw crusher. Its main function is to support and protect the body of the jaw crusher, reduce vibration during operation, and improve the stability and safety of the equipment.

[0003] The existing jaw crusher does not have a corresponding shock-absorbing structure, and the general shock-absorbing device has a poor shock-absorbing effect. In addition, since the jaw crusher will vibrate during operation, the lack of a shock-absorbing device will affect the use effect of the jaw crusher. In addition, since the jaw crusher is relatively heavy and inconvenient to move, the practicability of the jaw crusher is seriously affected.

[0004] For this purpose, we propose a protective base for a jaw crusher. Summary of the invention

[0005] The utility model aims to provide a protective base for a jaw crusher, which can solve the problem of severe shaking during the working process of the jaw crusher.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a protective base for a jaw crusher, comprising a bottom plate, a protective plate fixedly mounted on the top wall of the bottom plate, a mounting plate slidably mounted on the protective plate, a crusher body is arranged on the top wall of the mounting plate, an elastic pad is fixedly mounted between the top wall of the bottom plate and the mounting plate, a cavity is opened on the elastic pad, and an air intake valve and an exhaust valve are respectively inserted into the cavity.

[0007] Preferably, a mounting frame is fixedly mounted on the bottom wall of the base plate, the mounting frame is provided with rollers for driving the base plate to move, and a handrail is fixedly mounted on the base plate.

[0008] Preferably, a groove is provided on the mounting frame, a fixing rod is slidably installed in the groove, a spring is fixedly installed between the top wall of the fixing rod and the groove, and fixing grooves are evenly provided on the roller shaft.

[0009] Preferably, a coil electrically connected to the crusher body is embedded on the bottom plate, and a magnet block cooperating with the coil is embedded on the fixing rod.

[0010] Preferably, the bottom wall of the fixing rod is conical.

[0011] Preferably, a lubrication box is fixedly mounted on the bottom wall of the base plate, the lubrication box is filled with lubricating oil, the mounting frame is provided with a lubrication groove cooperating with the roller shaft, the lubrication groove is inserted with a lubrication pipe, and the lubrication box is provided with a pressure valve whose output end is connected to the lubrication pipe.

[0012] Preferably, an air pipe communicating with the lubrication box is fixedly mounted on the output end of the one-way valve.

[0013] Preferably, a sponge is embedded in the lubrication groove.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The present application sets an elastic pad, and the crusher body transmits the vibration to the elastic pad through the mounting plate. At this time, the elastic pad is deformed, and then the energy in the vibration process of the crusher body can be absorbed, so as to reduce the vibration amplitude of the crusher body during operation, and then improve the use effect of the crusher body. When the elastic pad is compressed, the gas in the cavity on the elastic pad is squeezed and flows out of the cavity through the exhaust valve. Then, when the elastic pad is stretched, the cavity inhales air through the intake valve. In the process of the cavity inhaling and exhausting air, the energy in the vibration process of the crusher body can be absorbed, which further reduces the vibration of the crusher body and improves the crushing effect.

[0016] 2. In this application, by setting the roller, the user can raise the handrail to push the bottom plate, and then the bottom plate drives the roller to roll through the mounting frame, which makes it convenient for the user to push the equipment. Then, when crushing work is needed, the user can first stop pushing the roller, and then start the crusher body. At this time, the coil is energized and generates a magnetic field. Then, under the action of the magnetic field, the magnet block drives the fixed rod to move downward. At this time, the spring is stretched and has a tendency to recover. In the process of the fixed rod moving downward, it is gradually inserted into the fixed groove. Then, under the cooperation of the fixed rod and the fixed groove, the roller is fixed, thereby effectively preventing the roller from rolling during the crushing process and affecting the crushing effect, thereby improving the crushing effect.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figures 1 to 5 , the utility model provides a technical solution:

[0027] A protective base for a jaw crusher comprises a base plate 1, a protective plate 2 is fixedly mounted on the top wall of the base plate 1, a mounting plate 3 is slidably mounted on the protective plate 2, a crusher body 4 is provided on the top wall of the mounting plate 3, an elastic pad 5 is fixedly mounted between the top wall of the base plate 1 and the mounting plate 3, a cavity 6 is opened on the elastic pad 5, and an intake valve 8 and an exhaust valve 7 are respectively inserted into the cavity 6.

[0028] During use, the crusher body 4 will vibrate under high-intensity working conditions. At this time, the crusher body 4 will transmit the vibration to the elastic pad 5 through the mounting plate 3. At this time, the elastic pad 5 will be deformed, and then the energy of the crusher body 4 in the shaking process can be absorbed, thereby reducing the vibration amplitude of the crusher body 4 during operation, thereby improving the use effect of the crusher body 4. When the elastic pad 5 is compressed, the gas in the cavity 6 on the elastic pad 5 is squeezed and flows to the outside of the cavity 6 through the exhaust valve 7. Then, when the elastic pad 5 is stretched, the cavity 6 inhales air through the intake valve 8. In the process of air intake and exhaust of the cavity 6, the energy of the crusher body 4 in the shaking process can be absorbed, further reducing the vibration of the crusher body 4 and improving the crushing effect.

[0029] Specifically, Figure 2 Figure 4 , Figure 5 As shown, a mounting frame 9 is fixedly mounted on the bottom wall of the base plate 1 , and the mounting frame 9 is provided with rollers 10 for driving the base plate 1 to move. An armrest is fixedly mounted on the base plate 1 .

[0030] The mounting frame 9 is provided with a groove, a fixing rod 11 is slidably installed in the groove, a spring 12 is fixedly installed between the top wall of the fixing rod 11 and the groove, and fixing grooves 13 are evenly provided on the rotating shaft of the roller 10 .

[0031] A coil 14 electrically connected to the crusher body 4 is embedded on the bottom plate 1 , and a magnet block 15 matched with the coil 14 is embedded on the fixing rod 11 .

[0032] The bottom wall of the fixing rod 11 is tapered.

[0033] By adopting the above technical solution, in the initial state, the spring 12 is in a freely extended state. When the crusher body 4 needs to be moved, the user can raise the handrail to push the bottom plate 1, and then the bottom plate 1 drives the roller 10 to roll through the mounting frame 9, which makes it convenient for the user to push the equipment. Then, when crushing work is needed, the user can first stop pushing the roller 10, and then start the crusher body 4. At this time, the coil 14 is energized and generates a magnetic field, and then the magnet block 15 drives the fixed rod 11 to move downward under the action of the magnetic field. At this time, the spring 12 is stretched and has a tendency to recover. In the process of the fixed rod 11 moving downward, it is gradually inserted into the fixed groove 13, and then the roller 10 is fixed under the cooperation of the fixed rod 11 and the fixed groove 13, thereby effectively preventing the roller 10 from rolling during the crushing process and affecting the crushing effect, thereby improving the crushing effect.

[0034] When the crushing is completed, the crusher body 4 is closed and stops working, then the coil 14 is powered off, and the magnetic field of the coil 14 disappears. At this time, the spring 12 contracts and drives the fixing rod 11 to move upward. During the upward movement of the fixing rod 11, it gradually loses contact with the fixing groove 13, playing a role in preparing for work again.

[0035] Specifically, Figure 2 , Figure 3 As shown, a lubrication box 16 is fixedly mounted on the bottom wall of the base plate 1, and the lubrication box 16 is filled with lubricating oil. A lubrication groove cooperating with the rotating shaft of the roller 10 is opened on the mounting frame 9, a lubrication pipe 17 is inserted into the lubrication groove, and a pressure valve 18 whose output end is connected to the lubrication pipe 17 is inserted into the lubrication box 16.

[0036] An air pipe 19 connected to the lubrication box 16 is fixedly installed on the output end of the one-way valve.

[0037] A sponge 20 is embedded in the lubrication groove.

[0038] By adopting the above technical solution, during the compression of the elastic pad 5, the air flow in the cavity 6 flows into the lubrication box 16 through the exhaust valve 7 and the air pipe 19, and the pressure in the lubrication box 16 increases. Then, under the action of the pressure, the lubricating oil in the lubrication box 16 flows into the lubrication groove through the pressure valve 18 and the lubrication pipe 17. Then, during the rotation of the roller 10, the lubricating oil can be applied to the rotating shaft of the roller 10, thereby reducing the friction force when the rotating shaft of the roller 10 rotates, thereby reducing the rotation resistance of the roller 10.

[0039] In the process of lubricating oil being applied to the shaft of the roller 10 through the lubrication groove, by setting the sponge 20, the sponge 20 can absorb the lubricating oil flowing into the lubrication groove, and then be evenly applied to the surface of the shaft of the roller 10 during the rotation of the shaft of the roller 10, so that the lubricating oil can be evenly applied to the shaft of the roller 10 while reducing the loss of the lubricating oil.

[0040] Working principle: When in use, the crusher body 4 will vibrate under high-intensity working conditions. At this time, the crusher body 4 will transmit the vibration to the elastic pad 5 through the mounting plate 3. At this time, the elastic pad 5 will deform, and then it can absorb the energy of the crusher body 4 during the vibration process, thereby reducing the vibration amplitude of the crusher body 4 during the working process, thereby improving the use effect of the crusher body 4, and when the elastic pad 5 is compressed, the gas in the cavity 6 on the elastic pad 5 is squeezed and flows to the outside of the cavity 6 through the exhaust valve 7, and then when the elastic pad 5 is stretched, the cavity 6 inhales air through the intake valve 8. In the process of air intake and exhaust of the cavity 6, the energy of the crusher body 4 during the vibration process can be absorbed, thereby further reducing the vibration of the crusher body 4; the user can raise the handrail to push the bottom plate 1, and then the bottom plate 1 drives the roller 10 to roll through the mounting frame 9, and then when crushing work is required, the user The operator can first stop pushing the roller 10, and then start the crusher body 4. At this time, the coil 14 is energized and generates a magnetic field. Then, under the action of the magnetic field, the magnet block 15 drives the fixing rod 11 to move downward. At this time, the spring 12 is stretched and has a tendency to recover. In the process of the fixing rod 11 moving downward, it is gradually inserted into the fixing groove 13. Then, under the cooperation of the fixing rod 11 and the fixing groove 13, the roller 10 is fixed, thereby effectively preventing the roller 10 from rolling during the crushing process; in the process of the elastic pad 5 being compressed, the air flow in the cavity 6 flows into the lubrication box 16 through the exhaust valve 7 and the air pipe 19, and the pressure in the lubrication box 16 is increased. Then, under the action of the pressure, the lubricating oil in the lubrication box 16 flows to the lubrication groove through the pressure valve 18 and the lubrication pipe 17. Then, in the process of the roller 10 rotating, the lubricating oil can be applied to the rotating shaft of the roller 10, thereby reducing the friction force when the rotating shaft of the roller 10 rotates.
