Sweet potato greenhouse temperature and humidity control device

Abstract

The invention discloses a sweet potato greenhouse temperature and humidity control device which is installed at the top in a greenhouse and comprises an installation base, a feeding mechanism used for driving the installation base to move and a control unit installed on the installation base. The control unit comprises an installation plate, a driving mechanism used for driving the installation plate to alternately rotate forwards and backwards and an air outlet assembly mounted on the lower surface of the installation plate, and the air outlet assembly comprises a second motor, a second rotating disc, a mounting rod, a shear fork air injection mechanism, a third connecting rod and a fan. The control unit is arranged, the second motor drives thesecond rotating disc to rotate, the second rotating disc drives a pin shaft to revolve, the pin shaft drives a mounting rod to swing in a reciprocating mode, the mounting rod drives a scissor-fork air injection mechanism to swing in a reciprocating mode, meanwhile, when the pin shaft moves, a scissor-fork rod of the scissor-fork air injection mechanism is driven to move through a third connecting rod, the shape of the scissor-fork air injection mechanism is changed, and therefore the air injection range is further expanded. The effective control range of the temperature and the humidity of the space in the whole greenhouse is widened, and the temperature and the humidity in the space of the greenhouse are kept consistent.

Description

technical field [0001] The invention relates to the technical field of greenhouses, in particular to a temperature and humidity control device for sweet potato greenhouses. Background technique [0002] Sweet potato: Also known as sweet potato, it is a twining herbaceous vine of the genus Dioscorea in the family Dioscoreaceae. [1] The terminal of the top branch of the underground tuber is swollen into an ovoid tuber, the skin is light yellow and smooth. Stems left-handed, spiny at base, covered with T-shaped pilose. Single leaves alternate, broad heart-shaped; male inflorescences are spikes, solitary, male flowers sessile or with very short stalks; bracts ovate, apex acuminate; perianth shallow cup-shaped, pubescent; capsule three Prismatic, apex slightly concave, base truncate, each edge winged; seeds round, winged. Flowering in early summer. [0003] When sweet potatoes are planted, a greenhouse is needed, so the temperature and humidity in the greenhouse need to be co...

AI Technical Summary

Problems solved by technology

[0003] When sweet potatoes are planted, a greenhouse is needed, so the temperature and humidity in the greenhouse need to be controlled. The existing control devices generally use hot air and cold air to control the temperature, and cooperate with the sprinkler device to control the humidity. The air outlet of the existing control device The positions are fixed, the control range is small, and the uniformity of the environment in the greenhouse cannot be guaranteed
