A semi-closed snow removal device

Abstract

The invention discloses a semi-closed snow removing device, which comprises a support frame, a snow removing device fixing plate, a rotating shaft, a chain wheel, a transmission chain, a scraping plate support frame, a scraping plate, a counter weight, a gear, a rotating shaft, a small chain wheel, a transmission chain, a rotating shaft, a rotating handle, a fixing plate, an upper chain baffle plate, a lubricating oil groove, a gear box and a chain transmission box. On the design concept, an efficient scraping technology is planned to be used for performing agricultural facility accumulated snow removal work; a power sources uses a manual rotation mode, so that the repair and maintenance are easy, and the mode better conforms to the practical conditions of agricultural production in China; great economic benefits can be obtained. In order to prolong the service life of the device, certain protection design is used on a transmission mechanism; a semi-closed structure is used by the upper transmission mechanism for driving the snow removing mechanism to work; a fully closed structure is used for the transmission gear and the lower transmission chain structure.

Description

technical field [0001] The invention relates to the field of agricultural production machinery and equipment, in particular to a semi-closed snow removal device. Background technique [0002] China is a country with a large population, and the supply security of agricultural products such as grain and vegetables is one of the important factors to ensure national security, stability and prosperity. Nowadays, greenhouse planting technology has been widely popularized in our country. This technology has important significance and role in increasing agricultural output, increasing the variety of agricultural products, and improving national living standards. However, this technology also has certain defects, especially it is difficult to deal with severe snowfall natural disasters. [0003] At this stage, the main technology and measures to deal with this situation is to adopt reinforced concrete skeleton structure greenhouses, and adopt arched design to enhance the supporting ...

AI Technical Summary

Problems solved by technology

[0004] Among the above two methods, the first measure has limited effect in the event of severe ice and snow weather disasters, it is difficult to guarantee that the mechanical damage of the greenhouse can be prevented, and the situation of snow accumulation in the greenhouse may still exist and have not been changed.

The second method requires a lot of labor intensity, and due to the height and structure of the greenhouse, it is extremely difficult and inconvenient to clean.

However, if the cleaning is not timely or the cleaning effect is not good, once the snow is not cleared in time, the snow will accumulate and become ice, and it will become more difficult to remove the snow in the future

If a vicious circle is formed, the snow accumulation will eventually overwhelm the entire agricultural facilities, causing irreparable economic losses and threats to personal safety.
