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

Embodiment 1

[0021] see Figure 1~2 , in an embodiment of the present invention, a sweet potato greenhouse temperature and humidity control device, which is installed on the top of the greenhouse, including a mounting base 8, a feed mechanism for driving the mounting base 8 to move, and a control unit installed on the mounting base 8, In this embodiment, the feed mechanism includes a threaded rod 1 that is rotatably installed on the top of the greenhouse, a first motor 2 for fixing the rotation of the threaded rod 1, and a guide rod that guides the mounting seat 8. The control unit includes Mounting plate 15, a drive mechanism for driving the mounting plate 15 to rotate forward and backward alternately, and an air outlet assembly mounted on the lower surface of the mounting plate 15, the mounting plate 15 is mounted on the lower surface of the mounting seat 8 through a mounting shaft and a bearing to drive The mechanism drives and connects the mounting shaft. In this embodiment, the drivin...

Embodiment 2

[0024] see image 3The difference between this embodiment of the present invention and Embodiment 1 is that, further, support rods 22 are hingedly mounted on both sides of the mounting plate 15, and the end of the support rod 22 away from the mounting plate 15 is rotatably mounted with a side tube 21. One end of the pipe 21 is hinged with the third connecting rod 16, and the side pipe 21 is connected with the air distribution pipe 18, and the outside of the side pipe 21 is uniformly provided with nozzles, and blowing air is blown to both sides through the setting of the side pipe 21, while the third connecting rod 16 moves to drive The swing of the side pipe 21 can further increase the blowing range and improve the control efficiency.

[0025] The working principle of the present invention is: when working, the temperature detector or the humidity detector monitors the temperature and humidity in the greenhouse, and when the preset value is exceeded, the fan 3 can be used to c...

Abstract

The invention discloses a sweet potato greenhouse temperature and humidity control device, which is installed on the top of the greenhouse and includes a mounting seat, a feed mechanism for driving the mounting seat to move, and a control unit installed on the mounting seat. The control unit includes a mounting plate, a drive mechanism for driving the mounting plate to alternate forward and reverse, and an air outlet assembly installed on the lower surface of the installation plate. The air outlet assembly includes a second motor, a second turntable, a mounting rod, a scissor jet mechanism, and a third connecting rod The fan is equipped with a control unit. The second motor drives the second turntable to rotate. The second turntable drives the pin shaft to revolve. The three connecting rods drive the movement of the scissor lever of the scissor jet mechanism, which makes the shape of the scissor jet mechanism change, thereby further expanding the spray range, improving the effective control range of the temperature and humidity in the entire greenhouse space, and making the temperature and humidity in the greenhouse space Be 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...
