Description

An adjustable height support for the vibrating shaft of a dust collector Technical Field

[0001] This utility model relates to the technical field of dust collectors, and in particular to the technical field of an adjustable height support for the vibrating shaft of a dust collector. Background Technology

[0002] The existing dust collector rapping shaft transmission process is as follows: the drive motor drives the small needle wheel to rotate, the small needle wheel drives the large needle wheel to rotate, realizing the transformation of vertical rotation into horizontal rotation, the large needle wheel drives the rapping shaft to rotate, the rapping shaft is supported by the support and limited by the adjusting ring and the baffle, thereby realizing long-distance transmission.

[0003] Because the rapping shaft is relatively long, it has a certain degree of deflection during transmission. With prolonged operation, the support beam and rapping shaft deflect more due to increased dust load and fatigue, causing the rapping shaft to jam and preventing subsequent transmission. Ultimately, this prevents the dust collector from rapping. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art by providing an adjustable height support for the rapping shaft of a dust collector. This support can be adjusted to prevent the rapping shaft from jamming and thus avoid affecting the rapping operation of the dust collector.

[0005] To achieve the above objectives, this utility model proposes an adjustable height support for a dust collector vibrating shaft, comprising a base, two sliding bodies, a shaft seat, and a bearing bush. The upper end of the shaft seat is provided with a mounting groove, and a bearing bush that mates with the vibrating shaft is provided in the mounting groove. Two sliding bodies are slidably arranged between the shaft seat and the base, and a bolt pair is provided between the two sliding bodies. The upper end of each sliding body is provided with a lower guide slope that is higher on the outside and lower on the inside. The shaft seat is supported on the lower guide slope. The lower end of the shaft seat is provided with two upper guide slopes that correspond one-to-one with and mate with the lower guide slopes.

[0006] Preferably, the lower end of the bearing seat is provided with a guide body that passes through the base, and the guide body is provided with an oblong hole through which the bolt pair can pass.

[0007] Preferably, the bolt assembly is secured by tightening with double nuts.

[0008] Preferably, a telescopic spring is fitted onto the bolt pair between the two sliding bodies.

[0009] Preferably, the bearing bush is provided with uniformly distributed through holes, and graphite is provided in the through holes.

[0010] Preferably, the convex surface of the bearing bush is provided with a positioning head, and the mounting groove is provided with a positioning groove that cooperates with the positioning head.

[0011] Preferably, the baffle also includes a receiving groove at the upper end for accommodating the vibrating shaft, and adjusting rings located on both sides of the baffle are fitted onto the vibrating shaft, the adjusting rings being fixedly connected to the vibrating shaft by screws.

[0012] The beneficial effects of this utility model are as follows: The upper end of the shaft seat has a mounting groove, and a bearing bush that mates with the vibrating shaft is installed in the mounting groove. Two sliding bodies are slidably arranged between the shaft seat and the base, and a bolt pair is provided between the two sliding bodies. Each sliding body has a lower guide slope with an outer higher surface and an inner lower surface at its upper end. The shaft seat is supported on the lower guide slope. The lower end of the shaft seat has two upper guide slopes that correspond to and mate with the lower guide slopes. By tightening the bolt pair, the two sliding bodies move towards each other. The two sliding bodies, through the cooperation of the lower and upper guide slopes, achieve the adjustment of the shaft seat's height. By loosening the bolt pair, the two sliding bodies can move in opposite directions under external force. The lower guide slope and the upper guide slope cooperate to adjust the descent of the bearing seat, thereby achieving support adjustment for the rapping shaft. This prevents the drive shaft from jamming due to excessive deflection and ensures the normal operation of the drive shaft. With the bearing bush setting, the bearing bush is a wear part, and only the bearing bush needs to be replaced. This avoids the high replacement cost and inconvenience caused by wear of the rapping shaft. Compared with the existing technology, it can support and adjust the rapping shaft, avoid the rapping shaft jamming, which would affect the rapping operation of the dust collector, and reduce the high replacement cost and make replacement convenient.
