Simple liquid storage type scraper and conveying device

Abstract

The invention relates to a simple liquid storage type scraper device and a conveying device. The simple liquid storage type scraper device comprises a scraper frame, a scraper assembly, a liquid storage device and an anti-disengagement protection assembly, wherein the scraper frame is fixed to the lower side of a conveying frame; the upper end of the scraper assembly is in abut joint with a conveying belt; and the lower end of the scraper assembly is rotationally connected with the scraper frame; liquid used for providing the gravity effect is stored in the liquid storage device; the liquid storage device adjusts the acting force of the upper end of the scraper assembly abutting against the conveying belt by changing the weight of the liquid; the anti-disengagement protection assembly is fixed onto the scraper frame; and when the scraper assembly is separated from the conveying belt, the anti-disengagement protection assembly transmits the scraper assembly to reset. The conveying device comprises a conveying frame, a conveying belt, a driving roller and the simple liquid storage type scraper device, wherein the driving roller is connected onto the conveying frame and supports the conveying belt. Through the liquid storage device, the material scraping pressure in contact with the conveying belt can be adjusted according to practical material scraping requirements, and the problem that the pressure is not adjustable in the material scraping process is solved.

Description

technical field [0001] The invention relates to the technical field of production and processing, in particular to a simple liquid storage type scraper and a conveying device. Background technique [0002] In the equipment with belt transportation, a scraper is generally installed at the front lower end of the front drum to scrape off the materials adhered to the belt. [0003] At present, the conventional scrapers are mainly spring-type and fixed-type, and there are disadvantages such as the contact between the newly replaced scraper leather and the belt is too tight, the friction force increases, the motor load increases, and the scraper leather has a short service life. As the scraper skin wears and becomes shorter, there is a situation that it is not in close contact with the conveyor belt. At this time, the material adhering to the conveyor belt is not easy to scrape off, and will fall to other areas under the belt with the operation of the belt, which is harmful to hyg...

Problems solved by technology

[0003] At present, the conventional scrapers are mainly spring-type and fixed-type, and there are disadvantages such as the contact between the newly replaced scraper leather and the belt is too tight, the friction force increases, the motor load increases, and the scraper leather has a short service life. As the scraper skin wears and becomes shorter, there is a situation that it is not in close contact with the conveyor belt. At this time, the material adhering to the conveyor belt is not easy to scrape off, and will fall to other areas under the belt with the operation of the belt, which is harmful to hygiene. Cleaning up brings big obstacles, which not only takes a lot of time and effort, but also increases the amount of labor

In order to avoid the situation that the scraped material is not clean, it is necessary to replace the scraper skin in time. Not only is it too frequent to replace the scraper skin, it is troublesome to replace, but also there is the problem that the pressure between the scraper skin and the conveyor belt cannot be adjusted.
