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...

Problems solved by technology

[0003] The application number is CN201520168368.9 patent, which is an open-close greenhouse structure for rice seedlings suitable for mechanized transplanting. Although it can make the mechanical transplanting seedlings rise and put the seedlings on the transplanter, the roots will not be broken, and the mechanical transplanting does not lack holes. Continuously ridges to ensure one-time transplanting and preservation of seedlings, but it does not have automatic functions and requires a lot of manpower

[0004] The application number is CN201720751115.3, which is a kind of greenhouse suitable for mechanized operations. Although the width of the shed door can be adjusted, the width of the shed door can be narrowed when people come in and out, so as to reduce the cold air from entering the shed. When the agricultural machinery enters and exits, the opening width of the shed door is widened so that the agricultural machinery can enter the greenhouse smoothly, but it cannot be easily and quickly opened the shed film to ventilate the greenhouse, and there is no automatic cover film Function, time-consuming and labor-intensive, and the device does not have the function of real-time detection of carbon dioxide concentration, farmers cannot grasp the carbon dioxide concentration of greenhouses in time, affecting crop yields
