Description

Technical Field

[0001] The utility model relates to a lubrication and noise reduction mechanism, in particular to a lubrication and noise reduction mechanism for a mineral processing shaking table. Background Art

[0002] The shaking table for mineral processing is generally composed of three parts: the bed surface, the frame and the transmission mechanism. In the transmission mechanism, the power of the motor is generally transmitted to the bed surface through the sprocket and chain transmission, and the main part of the noise is the transmission mechanism.

[0003] In the prior art, the sprocket and chain parts of the transmission mechanism are mainly filled with grease to reduce transmission noise and reduce component wear. The specific method is usually to apply grease manually. Since the sprocket and chain are located in the protective cover, it is inconvenient to apply grease. After long-term use and when the grease is insufficient, the noise in this part increases; on the other hand, the traditional sprocket and chain transmission cover does not have a sound insulation effect, resulting in high noise on site when the mineral processing shaking table is working, which deteriorates the operating environment. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a lubrication noise reduction mechanism for a mineral processing shaking table, which suppresses the noise generated by a transmission sprocket and a chain and further reduces the noise pollution degree when the shaking table is working by adding sound insulation measures.

[0005] The technical solution of the utility model is as follows:

[0006] The lubrication and noise reduction mechanism of the mineral processing shaking table includes a shaking table transmission device, the shaking table transmission device includes sprockets connected to each other by chains, and also includes a protective cover arranged on the outside of the chain, the protective cover is provided with a protective cover through hole on the upper side and is installed with a supporting fixing seat; the supporting fixing seat is provided with a supporting fixing seat through hole communicating with the protective cover through hole; a positioning plate is installed on the supporting fixing seat; an oil storage tank is installed on the upper side of the positioning plate, and a lubrication box is installed on the bottom side, the lubrication box passes through the supporting fixing seat through hole and the protective cover through hole and has a lubrication wheel installed inside; the oil storage tank is communicated with the lubrication wheel through oil-soaked cotton arranged in the lubrication box; the lubrication wheel protrudes downward from the bottom opening of the lubrication box and contacts with the chain.

[0007] Preferably, the positioning plate is provided with a longitudinal mounting hole located outside the oil storage tank; a limiting sleeve corresponding to the longitudinal mounting hole is fixedly installed on the upper side of the positioning plate; a limiting rod corresponding to the limiting sleeve is fixedly installed on the upper side of the support fixing seat; the limiting rod passes through the corresponding limiting sleeve and a fastening nut is connected to the upper end.

[0008] Preferably, the inner wall of the protective cover is provided with sound insulation cotton.

[0009] Compared with the prior art, the utility model has the following beneficial effects.

[0010] First, when the utility model is working, the lubricating oil in the oil storage tank is transferred to the lubricating wheel through the oil-soaked cotton. The lubricating wheel rotates with the chain as a driven wheel and provides lubrication for the chain. By continuously providing lubrication for the rocking table transmission device, the generation of transmission noise is further suppressed, and the degree of noise pollution when the rocking table is working is reduced.

[0011] Second, the oil storage tank of the utility model is connected to the lubricating wheel through the oil-soaked cotton arranged in the lubricating box. By replacing the oil-soaked cotton of different materials and densities, the transmission speed of the lubricating oil in the oil storage tank to the lubricating wheel can be changed, thereby controlling the amount of lubricant according to demand.

[0012] Third, the connection between the oil storage tank and the supporting fixing seat can be achieved by correspondingly putting the limiting sleeve on the limiting rod and then tightening the nut on the exposed part of the limiting rod. It has the characteristics of convenient assembly and disassembly and is easier to maintain.

[0013] Fourthly, the lubricating wheel of the utility model provides lubrication and at the same time acts as a tensioning wheel to squeeze the chain, thereby increasing the tensioning force of the chain and further reducing the noise generated by the cooperation of the chain and sprocket.
