Feedstuff lifting device

Abstract

The invention discloses a feedstuff lifting device capable of improving safety coefficients. The feedstuff lifting device comprises a lifter, a material tray and a protective fence. The material tray is suspended below the lifter; a loading and unloading opening is formed in the protective fence; and a button switch for controlling the lifter to ascend and descend is arranged at the position, beside the loading and unloading opening, of the protective fence. The feedstuff lifting device further comprises a protective rod and a stroke switch. One end of the protective rod is hinged to the position, on one side of the loading and unloading opening, of the protective fence; the other end of the protective rod is placed on the stroke switch; the stroke switch is fixed to the position, on the other side of the loading and unloading opening, of the protective fence; and the stroke switch is a control switch of a power source of the lifter. When the lifter is in a working state, a worker who wants to use the lifter can lift up the protective rod, after the protective rod is lifted up, the lifter stops working, the worker can check the working condition of the lifter or the position of the material tray safely, and therefore the safety coefficients can be further improved.

Description

technical field [0001] The invention relates to lifting equipment, in particular to a material tray lifting device. Background technique [0002] Since the equipment for producing and processing feed is arranged on different floors according to actual production requirements, in the process of feed production and processing, it is necessary to lift the required raw materials for production of feed to different floors with a lifting device according to the production situation. The lifting device includes a hoist and a tray, the tray is suspended under the hoist, and the hoist completes the lifting or lowering of the tray. There is a lifting opening on each floor, and there is a guardrail around the lifting opening. There is a loading and unloading port for loading and unloading raw materials on the guardrail. A button switch is installed on the top to control the rise or fall of the hoist. Since each floor is equipped with a protective fence, and there is a loading and unl...

AI Technical Summary

Problems solved by technology

Since each floor is equipped with a protective fence, and there is a loading and unloading port on the protective fence, when a certain floor is using the lifting device to lift raw materials, the noise of the production workshop is too loud, and the sound of the lifting device cannot be heard. It is also very difficult to communicate with the upper and lower floors. At this time, when the staff on other floors also need to use the lifting device, the staff need to stand at the loading and unloading port and stretch their heads downward or upward to see if anyone is using the tray. In this case, a little Carelessness may lead to a falling accident, or be injured by a falling or rising material tray
