Agricultural lifting device stall self-locking assembly utilizing electromagnetic pole changing principle

Abstract

The invention relates to an agricultural lifting device stall self-locking assembly utilizing an electromagnetic pole changing principle, and relates to the technical field of agriculture. The assembly comprises a mounting base, a main lifting wheel is movably connected to the top of the mounting base, a self-locking mechanism is movably connected to the front side of the main lifting wheel, and asecondary lifting wheel is arranged on the right side of the main lifting wheel. The agricultural lifting device stall self-locking assembly utilizing the electromagnetic pole changing principle doesnot influence normal use of equipment while a device normally works. When a hoisting device stalls and falls off, a rotating shaft of the lifting device is self-locked in time to prevent the hoistingdevice from continuing to descend, possible property and personnel losses are avoided, the safety of field constructors is guaranteed, the practicability and safety of the equipment are greatly guaranteed, requirements of China for safe production are better met, the production efficiency of agricultural product operators can be improved, and the income of the agricultural product operators can be further increased. Compared with the prior art, the reliability is higher.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a stall self-locking component of an agricultural lifting device utilizing the principle of electromagnetic pole change. Background technique [0002] With the development of modern technology, agricultural equipment is also gradually developing towards automation and mechanization. Compared with the previous manual labor, it not only improves the efficiency of production, but also saves a lot of time. [0003] my country's grain production has continued to grow in recent years, and domestic reserves are relatively sufficient. Therefore, some agricultural products have begun to be exported or undergo deep processing to create greater value. When exporting agricultural products, due to cost considerations, cargo ships are generally used for sea transportation, and agricultural products are lifted by aerial cranes and other equipment at the shipping dock. Due to the large we...

AI Technical Summary

Problems solved by technology

Frequent hoisting operations may cause the hoisting device to stall due to mechanical fatigue or excessive weight, that is, the hoisted objects drop rapidly, which poses a great safety hazard to the on-site operators and does not meet the national requirements for safe production. At the same time, the stall will not only cause damage to the equipment, but also cause additional losses to the hoisted objects, which seriously affects the income of the operators of agricultural products
