Headstock of mud scraper of sedimentation basin

Abstract

The invention discloses a headstock of a mud scraper of a sedimentation basin. The headstock is inserted in an installation bridge stand above the sedimentation basin and comprises a casing, inside which a first gear, a second gear and a pivotal bearing are installed. The first gear is engaged with the second gear; the second gear is engaged with external gear teeth of the pivotal bearing; a motoris installed on the upper surface of the casing, and an output shaft of the motor passes through a motor mounting hole and is connected with a center shaft of the first gear through a shaft coupling;the bottom of the pivotal bearing is provided with multiple cushion blocks for supporting; the cushion blocks are welded on a base plate of the casing; the main shaft of the mud scraper passes through a spindle hole to be installed in the pivotal bearing; an oil separator bucket is welded inside the casing and at the place corresponding to the spindle hole; and the casing is filled with gear oil,the liquid level of which is lower than height of the oil separator bucket. The headstock of the mud scraper of the sedimentation basin is directly inserted in the bridge stand; and with cooperationof the internal structure improvement, the pivotal bearing is always immersed in the gear oil. Thereby, abrasion and corrosion are minimized, and maintenance is convenient.

Description

technical field [0001] The patent of the present invention relates to a headstock, in particular to a headstock of a sludge scraper for a sedimentation tank. Background technique [0002] In the sedimentation tank of sewage treatment, the sludge deposited on the bottom or side wall of the tank needs to be scraped off by a sludge scraper. The structure of the crude oil is to use a three-stage cycloidal pinwheel reducer to control the sludge scraper, and its load is small. , the power of the motor is small, so it often occurs during use and the inside of the gear box is damaged, resulting in high maintenance costs. Secondly, the gear box is installed on the lower surface of the bridge above the sedimentation tank. Since the site is an open-air environment, it is corrosive , in order to increase the installation stability of the gearbox, various reinforcing ribs need to be set on the bridge frame, which makes it inconvenient to do anti-rust treatment on the bridge frame, result...
