Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, and in particular to an automatic oil injection device for a linear vibrating screen. Background Technology

[0002] Coal preparation plants use linear vibrating screens to dewater and demediate coal products. Vibrating screen bearings and exciter bearings are key components of linear vibrating screens, and also the most vulnerable components. Therefore, the quality of bearing installation, maintenance and upkeep directly affects the operation and screening effect of the vibrating screen.

[0003] When bearing lubrication is not timely or proper, it will affect the service life of the bearing and increase the failure rate of the vibrating screen. Coal preparation plants typically have multiple linear vibrating screens with numerous bearings, resulting in a large workload for lubrication. Two dedicated personnel are required daily to inspect and maintain the bearings. Manual lubrication is not very precise in terms of the amount of oil injected, and poor bearing lubrication leads to frequent failures, shortened lifespan, and increased operating and maintenance costs of the vibrating screen. Moreover, manual lubrication is inefficient. Some systems directly connect pipe joints to the oil injection holes for lubrication; however, under the long-term vibration of the linear vibrating screen, the joints are prone to loosening, affecting normal lubrication. Therefore, this utility model proposes an automatic lubrication device for linear vibrating screens to solve the problems existing in the prior art. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes an automatic oil injection device for a linear vibrating screen. This device connects to the bearing oil injection hole of the vibrator on the linear vibrating screen via a connector. Oil from the oil tank is pressurized by a grease pump and delivered to the oil injection hole through a flexible hose. After the connector is installed, rotating the nut ring causes the moving ring to descend along the guide groove, securing the clamping arm and rubber block onto the vibrator surface around the bearing oil injection hole. This provides a tightening force to the connector, preventing loosening after prolonged use.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: an automatic oil injection device for a linear vibrating screen, including a movable frame, an oil tank and an oil pump. The oil tank and the oil pump are located on the top of the movable frame. The input end of the oil pump is connected to the oil tank, and the output end of the oil pump is connected to a flexible hose. The output end of the flexible hose is provided with a fastening head, and one end of the fastening head is provided with a connector.

[0006] The fastening head has a sliding ring on its outer side, which is used to move and change position and position itself. The outer side of the sliding ring is connected to a clamping arm, and one end of the clamping arm is provided with a rubber block.

[0007] A further improvement is that the outer side of the fastening head is provided with a guide groove, and the inner side of the moving ring is provided with a guide protrusion that slides and adapts to the guide groove.

[0008] A further improvement is that the outer side of the fastening head is provided with an external thread, and the upper end of the moving ring is provided with a nut ring that is adapted to the external thread.

[0009] A further improvement is that the outer side of the connector is provided with screw teeth, and the connector is connected to the bearing oil injection hole of the vibrator on the linear vibrating screen through the screw teeth.

[0010] A further improvement is that the grease pump is equipped with a timing controller, which is used to control the oil supply time and interval shutdown time of the grease pump. An oil pressure gauge is connected between the output end of the grease pump and the flexible hose.

[0011] A further improvement is that the mobile frame includes a base frame and a side frame, the side frame is connected to one side of the base frame, and both ends of the connection between the side frame and the base frame are rotatably provided with wheels. The oil tank and grease pump are located above the base frame, and a storage rack is provided on the upper inner side of the side frame, and the storage rack is used to store the flexible hose.

[0012] A further improvement is that a viewing window is provided on one side of the fuel tank, and an oil cap is provided on the top of the fuel tank.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses a connector to connect with the bearing oil injection hole of the vibrator on the linear vibrating screen. The oil in the oil tank is pressurized by a grease pump and transported to the oil injection hole through a flexible rubber hose. After the connector is installed, the nut ring is rotated. The matching action of the nut ring and the external thread drives the moving ring to descend along the guide groove, which locks the clamping arm and rubber block on the vibrator surface around the bearing oil injection hole, giving the connector a tight force and preventing it from loosening after long-term use.

[0015] 2. This utility model controls the oil supply time and interval shutdown time of the grease pump through a timer controller. The grease pump pressurizes the oil in the oil tank and delivers it to the oil injection hole through a flexible hose, which automates the oil injection process, reduces manual maintenance and upkeep of the equipment, extends the service life of the vibrator bearing, and reduces the equipment failure rate.
