Efficient spraying device for agricultural greenhouse

Abstract

The invention discloses an efficient spraying device for an agricultural greenhouse. The device comprises a greenhouse roof, a working frame is fixedly mounted on the bottom of the greenhouse roof through supports, a variable frequency motor is arranged on the top of the working frame, a first rotary shaft is connected with a motor shaft at the bottom end of the variable frequency motor, second rotary shafts are connected to the left and right side walls of the interior of the working frame in a rotational mode, a first cam is mounted on the second rotary shaft on the right side, and a second cam is mounted on the second rotary shaft on the left side; pressurizing cylinders are arranged on the left and right sides of the bottom wall of the working frame, a piston is arranged in each pressurizing cylinder, the piston rod at the top end of each piston penetrates through the top wall of the corresponding pressurizing cylinder to be connected with a pressing plate, the bottom of each pressing plate is connected with the top of the corresponding pressurizing cylinder through springs, a water outlet tube and a water inlet tube are further connected with the bottom of the interior of each pressurizing cylinder, and check valves are arranged on the water outlet tubes and the water inlet tubes. According to the device, the cams rotate to drive the pistons to move vertically in the pressurizing cylinders so that automatic spraying can be conducted, the spraying speed can be changed through changing the speed of the variable frequency motor, control is simple, and use is convenient.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to an efficient spraying device for agricultural greenhouses. Background technique [0002] Agriculture is an industry that uses the growth and development laws of animals and plants to obtain products through artificial cultivation. Agriculture belongs to the primary industry, and the science that studies agriculture is agronomy. The objects of labor in agriculture are living animals and plants, and the products obtained are the animals and plants themselves. Agriculture provides basic products that support the construction and development of the national economy. At present, greenhouses are needed in the process of agricultural development to improve production efficiency, and sprinklers are needed for greenhouse cultivation to sprinkle water on internal plants. [0003] At present, in the spraying of greenhouses, the staff generally use manual sprinklers to work. Although...

Problems solved by technology

[0003] At present, in the spraying of greenhouses, the staff generally use manual sprinklers to work. Although the expected effect can be achieved, it is time-consuming and laborious, and the work efficiency is low. Some of them use mechanical sprinklers to spray water. The structure of ordinary sprinklers is relatively Complicated, adjusting the position of the nozzle during the water spraying process is prone to dead angles, resulting in uneven spraying
