Description
Technical Field
[0001] The utility model relates to the field of jaw crushers, in particular to an oil injection lubrication device for jaw crushers. Background Art
[0002] Jaw crusher is commonly known as jaw crusher, also known as tiger mouth. It consists of two jaw plates, the moving jaw and the static jaw, forming a crushing chamber. It simulates the movement of the two jaws of animals to complete the material crushing operation. It is widely used in the crushing of various ores and bulk materials in the mining and smelting, building materials, highways, railways, water conservancy and chemical industries. The bearing is an important part of the jaw crusher. The bearing is the part where the bearing and the journal contact. The lubrication of the bearing directly affects the service life of the jaw crusher.
[0003] After searching, the Chinese patent "An automatic oiling device for jaw crusher" has the authorization announcement number "CN 214332261U". This patented technology injects lubricant into the jaw plate and bearing by arranging an oil pump, an oil tank, and a distributor on the crusher body. The injection of lubricant can be controlled by controlling the oil pump. Therefore, it is simpler, reduces the labor intensity of operators, reduces safety hazards, and is safe, labor-saving, simple and efficient.
[0004] Although the patented technology solves the problem that the existing crusher is manually added with grease, and a special person is required to add grease when the coarse crusher is running, which is not only labor-intensive but also has safety hazards. However, the patented technology draws lubricant from the oil tank through an oil pump and transports it from the oil outlet pipeline to the distributor. The distributor sends the lubricant to the jaw plate and bearing for lubrication through a branch pipeline and an oil nozzle. The connection between the pipeline and the oil nozzle will cause the pipeline seal to fail due to long-term use. The failure of the seal at the connection between the pipeline and the oil nozzle will cause the lubricating oil to overflow. The overflowed lubricating oil will evaporate some of the water when it is in contact with the air for a long time, causing the viscosity of the lubricating oil to increase, and it will adhere to dust and sand in the air. The overflowed lubricating oil will be added to the bearing together with the new lubricating oil, making it difficult to ensure the quality of the lubricating oil in the bearing, which will cause damage to the bearing. Therefore, an oil filling and lubrication device for a jaw crusher is proposed to solve the above problems. Utility Model Content
[0005] The purpose of the utility model is to provide an oil filling and lubrication device for a jaw crusher in order to solve the above-mentioned problem, which improves the problem that the overflowed lubricating oil will evaporate part of the water when in contact with the air for a long time, causing the viscosity of the lubricating oil to increase, and adhere to the dust and sand in the air. The overflowed lubricating oil will be added into the bearing together with the new lubricating oil, making it difficult to ensure the quality of the lubricating oil in the bearing, which will cause damage to the bearing.
[0006] The utility model achieves the above-mentioned purpose through the following technical scheme: an oil injection and lubrication device for a jaw crusher, an oil injection and lubrication device for a jaw crusher, comprising a jaw crusher, one side of the jaw crusher is fixedly connected with two fixed frames, an oil injection pipe is arranged in the fixed frame; a cleaning component, the cleaning component comprises an electric telescopic rod fixedly connected to the top of the fixed frame, the bottom of the electric telescopic rod is fixedly connected with a push plate, a water pipe is embedded and installed in the fixed frame, the other end of the water pipe is embedded and installed in the push plate, a shunt pipe is opened in the oil injection pipe, and a sealing plug is embedded and installed in the shunt pipe.
[0007] Preferably, an oil pipeline is arranged in the fixing frame, and the oil filling pipe and the oil pipeline are axially symmetrically distributed. When the oil filling pipe and the oil pipeline are not needed, the oil filling pipe and the oil pipeline can be fixed in the fixing frame, which can prevent the oil filling pipe and the oil pipeline from dust while cleaning, and prevent dust and sand in the air from floating into the oil filling pipe and the oil pipeline.
[0008] Preferably, a movable groove is opened in the fixed frame, and the push plate is slidably connected in the movable groove. The movable groove can limit the oil pipeline, the oil filling pipe and the push plate to ensure that the push plate can accurately enter the oil filling pipe and the oil pipeline when moving downward without deviation.
[0009] Preferably, the oil filling pipe is located below the push plate, and the outer diameter of the push plate is consistent with the outer diameter of the oil filling pipe, which can ensure that the push plate can scrape off the oil stains accumulated on the inner wall of the oil filling pipe to prevent the situation where the oil stains are not cleaned cleanly when the outer diameter of the push plate is smaller than the inner diameter of the oil filling pipe.
[0010] Preferably, a tilt control plate is provided in the oil filling pipe, and the tilt control plate is located on one side of the diverter pipe. When the lubricating oil is added, the tilt control plate will be at a vertical angle and will not block the filling of the lubricating oil. When the oil filling pipe needs to be cleaned, the tilt control plate will be at a horizontal angle to prevent the oil stains cleaned by the push plate from falling into the oil filling pipe.
[0011] Preferably, the height of the tilt control plate is consistent with the height of the shunt pipe, which can ensure that the oil stains cleaned by the push plate can flow out through the shunt pipe and will not remain in the oil filling pipe.
[0012] Preferably, a control valve is fixedly connected inside the tilt control plate, and the control valve is located on the surface of the oil filling pipe. The tilt angle of the tilt control plate can be controlled by the control valve, so that the tilt angle can be adjusted at any time when adding lubricating oil and cleaning the oil filling pipe.
[0013] Preferably, one side of the jaw crusher is fixedly connected to an oil tank, a counterweight is embedded in the oil tank, one end of the oil filling pipe and the oil delivery pipe are both connected to the bottom of the oil tank, and the lubricating oil in the oil tank is squeezed by the counterweight, so that the lubricating oil in the oil tank can be injected into the bearing shell through the oil filling pipe, which is more convenient.
[0014] The beneficial effects of the utility model are:
[0015] 1. Fix the oil filling pipe in the moving groove, and seal the oil filling pipe by tilting the control plate. Then, the electric telescopic rod will drive the push plate to move downward to clean the oil stains in the oil filling pipe. At the same time, pull out the plug in the shunt pipe, and the cleaned oil stains will flow out through the shunt pipe. Then, water is injected into the oil filling pipe through the water pipe to cooperate with the push plate to further clean the oil filling pipe to prevent the overflowed lubricating oil from being added into the bearing bush along with the new lubricating oil, causing damage to the bearing bush.
[0016] 2. By providing a sealing plug, when the sealing plug is pulled out, the cleaned oil stains can flow out through the shunt pipe, and when the sealing plug is reinserted into the shunt pipe, it can play a sealing role to prevent leakage when filling the lubricating oil. At the same time, it can prevent air from entering the oil filling pipe and causing the lubricating oil in the oil tank to be corroded. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] like Figure 3 and Figure 4 As shown, an oil delivery pipe 4 is arranged in the fixed frame 2, and the oil filling pipe 3 and the oil delivery pipe 4 are axially symmetrically distributed, a movable groove 21 is opened in the fixed frame 2, and a push plate 52 is slidably connected in the movable groove 21, and the oil filling pipe 3 is located below the push plate 52, and the outer diameter of the push plate 52 is consistent with the inner diameter of the oil filling pipe 3, and a tilt control plate 6 is arranged in the oil filling pipe 3, and the tilt control plate 6 is located on one side of the diverter pipe 54, and a control valve 61 is fixedly connected in the tilt control plate 6, and the control valve 61 is located on the surface of the oil filling pipe 3. First, the oil filling pipe 3 is fixed in the movable groove 21, and then the tilt angle of the tilt control plate 6 is changed by rotating the control valve 61, so that the tilt control plate 6 maintains a horizontal angle, and the oil filling pipe 3 is blocked, and then the oil stains in the oil filling pipe 3 are cleaned by moving the push plate 52 downward, and the cleaned oil stains will flow out through the diverter pipe 54, thereby preventing the oil stains from accumulating in the oil filling pipe 3.
[0025] like Figure 1 and Figure 2 As shown, one side of the jaw crusher 1 is fixedly connected to an oil tank 7, and a counterweight 71 is embedded in the oil tank 7.
