Agricultural mechanical tent

Abstract

The invention discloses an agricultural mechanical tent. The agricultural mechanical tent comprises sliding rails, supporting boards, a moving rack, a motor I, a ball screw, rotating racks, a rotatingshaft, a bevel gear I, a bevel gear II, a turbine, a worm, a gear shaft, a motor II and a thin film. By means of the agricultural mechanical tent, an automatic film covering function is achieved, labor is greatly saved, the working efficiency is improved, when a device is in use, the motor II is started first, the worm and the shaft of the motor II rotates simultaneously, the worm is in transmission with the turbine in a meshed mode, the turbine and the bevel gear II rotate simultaneously, the bevel gear I is in transmission with the bevel gear II in a meshed mode, thus through the rotating shaft, the rotating racks rotate at a certain angle until the bottom ends of the other sides of the rotating racks are attached to a rack, then the motor I is started, the shaft of the motor I drives the ball screw to rotate and then drives the moving rack to move linearly from one supporting board to a position attached to the inner side of the other supporting board, and thus the thin film automatically covers the rotating racks; by means of the device, real-time monitoring the carbon dioxide concentration in a greenhouse and illumination are further achieved.

Description

technical field

[0001] The invention relates to the field of modern agricultural machinery, in particular to an agricultural machinery tent. Background technique

[0002] With the emergence of high molecular polymers - polyvinyl chloride and polyethylene, plastic films are widely used in agriculture. In the early 1950s, Japan, European and American countries successfully applied greenhouse films to cover hotbeds, and then covered small sheds and greenhouses with good results. my country introduced polyvinyl chloride agricultural film in the autumn of 1955. It was first used to cover vegetables in small sheds in Beijing, and achieved the effect of early maturity and increased production. The greenhouse was originally a special equipment for vegetable production. With the development of production, the application of greenhouses has become more and more extensive. At present, greenhouses have been used for potted flower and cut flower cultivation; fruit tree production is us...
