Description

Technical Field

[0001] The present invention relates to the technical field of single-cylinder cone crushers, and more particularly, to a hydraulic oil supply device for a single-cylinder cone crusher. Background Art

[0002] A cone crusher is a crushing machine suitable for raw materials in the metallurgical, construction, road-building, chemical, and silicate industries. According to different crushing principles and different product particle sizes, it is divided into many models. The crusher is widely used in many departments such as mines, smelting, building materials, highways, railways, water conservancy, and chemical industries. The cone crusher has a large crushing ratio, high efficiency, low energy consumption, and uniform product particle size, and is suitable for medium crushing and fine crushing of various ores and rocks. With the development of the cone crusher towards the trend of large-scale, the requirements and complexity for lubrication and hydraulics are higher. In order to meet the lubrication requirements of the gear bearings of large multi-cylinder cone crushers and the hydraulic transmission requirements of the main equipment, technical requirements such as large flow rate, high pressure, and high performance of lubrication are realized.

[0003] In the prior art, a hydraulic oil automatic supply device for a multi-cylinder cone crusher with the publication number of CN218717909U includes a support box. A pressure switch is installed at the upper end of the overflow valve, and a connecting wire is electrically connected to one side of the pressure switch. The other end of the connecting wire is electrically connected to a booster pump, and a gas guide pipe is connected to the upper end of the booster pump. The other end of the gas guide pipe is connected to the overflow valve. A large oil replenishment tank is arranged on one side of the fuel tank of the hydraulic oil automatic supply device for the multi-cylinder cone crusher, and a liquid level switch is installed at the lower end of one side of the inner wall of the fuel tank to detect the oil level. When the detected oil level is too low, the host can be controlled by PLC to start the water pump, so that the oil in the oil replenishment tank can be introduced into the fuel tank through the suction port for oil replenishment. And the overflow valve of this device can be detected through the pressure switch. When the oil pressure is too low, the pressure can be replenished through the booster pump, which is more automatic and safer to use.

[0004] However, when the existing oil supply device is in use, although it can better perform the oil supply operation for the required oil, it often uses a single supply pipe for the oil supply operation, and the multi-path transportation effect of the oil is not good. And after the oil is transported, the delivery pipe is often set in a normal state, and the closing effect of the inner cavity of the delivery pipe is not high, which affects the transportation stability of the oil pressure inside the delivery pipe and does not meet the usage requirements of people. For this reason, we propose a hydraulic oil supply device for a single-cylinder cone crusher. Summary of the Invention

[0005] To solve the problems mentioned in the above background, the present invention provides a hydraulic oil supply device for a single-cylinder cone crusher, so as to solve the problems that in the above-mentioned background art, the oil is often supplied through a single supply pipe, the multi-path transportation effect of the oil is not good, and after the oil is transported, the closing effect of the inner cavity of the transportation pipe is not high, affecting the transportation stability of the oil pressure inside the transportation pipe.

An oil injection hole is formed in the outer wall of the lifting pipe. When it is necessary to supply oil, in order to improve the versatility of the oil delivery box in using oil and the effect of supplying oil in a tidal state, through the movement of the lifting block, the adapter cylinder is driven to move upward, so that the oil enters the inside of the adapter cylinder, and the sealing plate is extruded, and the oil is continuously transported. When the lifting pipe rises, the oil injection hole will be docked with the external oil delivery pipe, and under the action of the extraction pump, the oil will automatically supply in a tidal state, improving the versatility of multi-path use of the oil.

[0007] Preferably, one end of the delivery pipe is detachably connected to a conversion box. An oil injection pipe is detachably connected to the outer wall of the conversion box.

When injecting oil into the hydraulic rod through the oil injection pipe, in order to improve the regulating effect on the oil injection speed, the conversion box is threadedly connected to the external spiral through a fastening block, so that the delivery pipe, the oil injection pipe and the adapter pipe are respectively connected to the conversion box, expanding the oil replenishment path and improving the control effect on the oil supply speed.

[0008] Preferably, a connector is fixedly connected to the outer wall of the conversion box. A fastening block threadedly connected to the outer wall of the delivery pipe is sleeved on the outer wall of the connector. An internal helix is provided on the inner wall of the fastening block, and an external helix threadedly connected to the surface of the internal helix is provided on the outer wall of the delivery pipe.

[0009] Preferably, an oil flow chamber is provided inside the conversion box. A communication port with a cross-shaped cross-section is provided on the inner wall of the conversion box. The overall materials of the oil injection pipe and the connection pipe are both made of transparent materials.

When the oil is continuously transported by the operation of the oil pump, during the impact of the oil transportation, the adjustment plate will be driven to perform an automatic flipping motion, and the connection gear will be driven to perform a synchronous flipping motion, so as to achieve an adaptive buffering effect on the oil when there is a certain height difference in the oil, and reduce the impact force of the oil on the pipeline.

[0011] Preferably, the outer wall contour of the extrusion part of the locking rod and the connection gear is beveled. The connection blocks are respectively arranged in one-to-one correspondence with the oil injection pipe and the connection pipe, and the positions of the two groups of connection blocks are arranged at the same height. When the crusher does not need to be replenished with oil, in order to improve the sealing effect of the oil transportation chamber and reduce the reaction of the air pressure on the inside of the pipeline, after the oil impacts the adjustment plate and causes the adjustment plate to flip, the operator can manually rotate the connection gear to make the adjustment plate parallel to the sealing ring, so as to change the state of the adjustment plate and achieve the effect of conveniently sealing the oil transportation chamber when it is not in use.

Through the rotation of the swing rod, the elevator block is driven to slide along the inner wall of the limiting groove, and the lift pipe is driven to slide along the inner wall of the second connecting cylinder, so that the oil injection hole is docked with the external oil delivery pipe, and the connecting cylinder is driven to move upward synchronously, driving the connecting cylinder to exceed the sealing groove, so that the oil liquid flows into the connecting cylinder from the gap between the connecting cylinder and the sealing plate. Under the connection of the second spring, the reciprocating rod and the sealing plate are pressed downward, so that the oil liquid is conveyed from the oil injection hole into the external oil delivery pipe and then conveyed into the oil storage box to automatically replenish the oil liquid.

[0018] 3. By setting the adjusting plate in the present invention, when the oil liquid is continuously conveyed through the operation of the oil pump, the impact of the oil liquid delivery will drive the adjusting plate to perform an automatic flipping movement and drive the connecting gear to perform a synchronous flipping movement, playing an adaptive buffering effect on the oil liquid when there is a certain height difference, reducing the impact force of the oil liquid on the pipeline.

[0019] 4.
