Automatic elevator

Abstract

The invention discloses an automatic elevator. The automatic elevator comprises a vertical frame and an inclined frame, wherein an electric motor is installed on the vertical frame, an output shaft of the electric motor drives a rotating shaft, a lifting steel wire is equipped on the rotating shaft, the top end of the inclined frame is hinged to the top end of the vertical frame, a buckle is arranged on the vertical frame, a movable lifting frame is arranged on the inclined frame, and the lifting frame is drawn by one end of the lifting steel wire. The automatic elevator is characterized in that an upper stopping switch and a lower traveling switch are arranged on a cross beam of the upper end of the inclined frame, a lower stopping switch and an upper traveling switch are arranged at the bottom end of the inclined frame, and the upper stopping switch, the lower traveling switch, the lower stopping switch and the upper traveling switch are electrically connected with the electric motor. According to the automatic elevator, automatic lifting and descending operation under different working conditions can be achieved, manual operation is reduced, and the automatic elevator is small in size and good in portability.

Description

technical field [0001] The invention relates to an agricultural transportation auxiliary device, in particular to an automatic hoist. Background technique [0002] As we all know, in modern industrial and agricultural production activities, the hoist is an indispensable facility in the process of logistics and transportation. There are many types of hoists, but in the agricultural production process, the hoist is not widely used. The reason At present, hoists are mostly distributed in factories, construction sites and other places with complete supporting facilities. However, due to the lack of external conditions for farmers in the fields of grain transportation and the large size of existing hoists, some hoists are not highly automated. A large amount of manpower is used together, so it is not suitable for single-family farmers to use. Therefore, at present, the majority of farmers are still using a lot of manpower in the transportation of food and materials. Contents of...
