Embodiment 1

[0025] Such as Figure 1-5 As shown, a lubrication system for the bearing of a vertical shaft impact crusher includes an oil supply pipe 17 and an oil return pipe 5 connected to the bearing cylinder 4, and the bearing cylinder 4 is connected to the lubricating oil tank through the oil supply pipe 17 and the oil return pipe 5 , the oil supply pipe 17 and the oil return pipe 5 are all selected high-pressure oil pipes, which have a long service life. An oil hole is processed on the side wall of the bearing cylinder 4. The upper end of the oil hole communicates with the upper end of the inner cavity of the bearing cylinder 4, and the oil supply pipe 17 communicates with the lower end of the oil hole. , and then the lubricating oil can be delivered to the upper end of the inner cavity of the bearing cylinder 4, and the oil return pipe 5 communicates with the lower end of the inner cavity of the bearing cylinder 4, so that the oil inlet pipe and the oil return pipe 5 can be installed...

Embodiment 2

[0034] Such as Image 6 As shown, a lubrication system for vertical shaft impact crusher bearings is different from Embodiment 1 in that a pressure sensor 25 is installed at the detection port, and the trigger device includes an elastic sealing film 23 installed at the detection port, and the elastic seal A force transmission block 24 is installed between the membrane 23 and the pressure sensor 25. More specifically, a connection sleeve 26 is threadedly installed at the detection port, and an elastic sealing film 23 is installed on the lower end of the connection sleeve 26. A pressure sensor is installed on the upper end of the connection sleeve 26. 25, between the pressure sensor 25 and the elastic sealing film 23, the force transmission is fast, and the force transmission block 24 is made of compressed sponge, which is light in weight and can transmit pressure. The connection sleeve 26, the pressure sensor 25, the elastic sealing film 23, and the force transmission block 24 ...

Embodiment 3

[0036] Such as Figure 7 As shown, a lubrication system for vertical shaft impact crusher bearings is different from Embodiment 1 in that the vent pipe 6 is connected with a vertical pipe 704. In this embodiment, the lower end of the vertical pipe 704 is connected to the vent pipe 6 through a joint 706. When in use, the lubricating oil is low-viscosity oil, which is pressurized by the booster pump 9 and reaches the upper end of the bearing cylinder 4, and then flows downward through the bearing in the form of self-flow. Since the lubricating oil heats up and expands during the operation of the bearing, The pressure in the bearing cylinder 4 can be kept stable by the standpipe 704. In order to ensure that the standpipe 704 is upward, a support rod 705 is fixed on the upper end of the standpipe 704, and the support rod 705 is connected to the lower body 3 to prevent debris from falling into the standpipe 704. , the upper end of the standpipe 704 is bent downward.

Abstract

The invention relates to crushing equipment, in particular to a lubricating system for a bearing of a vertical shaft impact crusher, which comprises an oil supply pipe and an oil return pipe which are communicated to a bearing cylinder, the bearing cylinder is communicated to a lubricating oil bin through the oil supply pipe and the oil return pipe, and the oil supply pipe is connected with a supercharging device. The oil return pipe is connected with a flow detection device and / or an oil pressure detection device is arranged in the bearing cylinder, the pressurizing device comprises a pressurizing pump, lubricating oil is pumped into the bearing cylinder through the pressurizing device, flowing is more stable after pressurization due to the viscosity of the lubricating oil, oil is supplemented to the bearing cylinder, and meanwhile heat of the bearing cylinder can be taken away; the oil pressure detection device comprises a trigger device arranged in the bearing cylinder and a detection device matched with the trigger device, due to the fact that the detection head is prone to being stained by lubricating oil, the oil pressure in the bearing cylinder is high, the trigger device and the detection device are arranged, the detection device can be protected, and meanwhile the detection precision can be improved; and the defect that the detection device is easy to stain is overcome.

Description

technical field [0001] The present invention relates to crushing equipment and in particular to a lubrication system for bearings of vertical shaft impact crushers. Background technique [0002] Vertical shaft impact crusher is widely used to provide high-quality sand and gravel aggregates for highways, high-rise buildings, concrete mixing plants, etc. It is the preferred equipment in the field of machine-made sand and stone shaping. In order to improve production efficiency and reduce maintenance labor intensity, thin oil lubrication is generally used. The existing lubrication system cannot detect whether the lubricating oil has reached the bearing position. shutdown. Cause the bearing to rotate without lubricating oil, causing bearing damage. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies in the prior art and provide a lubrication system for bearings of vertical shaft impact crushers that can effectively protect t...
