For those of ordinary skill in the art, the specific meanings of the above terms in this patent can be understood according to specific circumstances.

[0030] Embodiment 1

[0031] Please refer to Figures 1-4 , an automatic temperature and humidity equalization device for an agricultural cabin provided in this embodiment includes a hoisting reciprocating mechanism 1 and a temperature and humidity adjustment mechanism 2. The hoisting reciprocating mechanism 1 includes a hoisting sliding assembly 11 and a reciprocating motion assembly 12 that are matched and arranged.

[0032] In this embodiment, the hoisting sliding assembly 11 includes a track 111 and a plurality of hanging pulleys 112. The hanging pulleys 112 are slidably sleeved on the track 111 and can slide left and right along the track 111. There are two tracks 111 in this embodiment, and they are parallelly installed on the lower surface of the top of the agricultural cabin 3. The lower part of the hanging pulley 112 is detachably connected to the air box assembly 22, such as bolt connection, etc., which will not be elaborated here;

[0033] The reciprocating motion assembly 12 in this embodiment includes a driving unit 121, a transmission unit 122, and a commutation unit 123. The transmission unit 122 is power-connected to the driving unit 121 and is connected to the bellows assembly 22 through the commutation unit 123. In this embodiment, the driving unit 121, the transmission unit 122, and the commutation unit 123 cooperate with each other to enable the bellows assembly 22 to perform a controlled reciprocating motion along the direction of the track 111. Specifically:

[0034] The driving unit 121 includes a reduction motor 1211 and a friction wheel 1212 mounted on the rotating shaft of the reduction motor 1211. The transmission unit 122 in this embodiment is a steel wire rope, and the commutation unit 123 is a commutation pulley group. A groove can be provided on the friction wheel 1212 in this embodiment to match the steel wire rope 122 to prevent the steel wire rope 122 from falling off. Of course, a reduction motor 1211 matching a gear can also be used as the driving unit, and a chain can be used as the transmission unit, but preferably a steel wire rope is used, which can reduce the weight and improve the flexibility.

[0035] The reduction motor 1211 and the commutation pulley group 123 in this embodiment are respectively installed on two opposite inner walls of the agricultural cabin 3; one end of the steel wire rope 122 is fixedly connected to the bellows assembly 22, and the other end bypasses at least two weeks around the friction wheel 1212 and then bypasses the commutation pulley group 123 to be connected to the bellows assembly 22. Generally, two turns are sufficient, which can increase the friction and prevent the steel wire rope 122 from slipping;

[0036] In this embodiment, in order to further increase the pressure between the steel wire rope 122 and the friction wheel 1212 and the commutation pulley group 123 to increase the friction, particularly, a tension spring 124 is connected between the steel wire rope 122 and the bellows assembly 22.

[0037] The commutation pulley group 123 in this embodiment includes two fixed pulleys. The steel wire rope 122 bypasses one of the fixed pulleys and abuts against the other fixed pulley, further increasing the tension degree of the steel wire rope 122.

[0038] The temperature and humidity adjustment mechanism 2 in this embodiment includes a matching air duct assembly 21 and a bellows assembly 22, wherein,

[0039] The air duct assembly 21 includes a telescopic hose 211 and an air inlet 212. One end of the telescopic hose 211 is communicated with the air inlet 212, and the other end is connected to the bellows assembly 22; the air inlet 212 in this embodiment is communicated with the air outlet of the air conditioning device.

[0040] The bellows assembly 22 in this embodiment includes a box body 221, a humidity adjustment module, and an air outlet adjustment module 222. In this embodiment, hanging ears 2211 are provided above the box body 221, and the lower part of the hanging pulley 112 is detachably connected to the hanging ears 2211. One end of the telescopic hose 211 is connected to the box body 221 to introduce the cold or hot air of the air conditioning device into the box body 221.

[0041] The humidity adjustment unit in this embodiment is installed inside the box body 221. Generally, a spray humidifier is used as the humidity adjustment unit. The spray humidifier can work automatically according to the humidity data collected by the sensor. The air outlet adjustment module 222 in this embodiment is communicated with the box body 221. There are two air outlet adjustment modules 222 in this embodiment, and they are symmetrically arranged on both sides of the box body 221. Of course, more air outlet adjustment modules 222 can also be set according to needs, which will not be elaborated here.

[0042] The air outlet adjustment module 222 in this embodiment includes a branch pipe 2221. The free end of the branch pipe 2221 is a flared opening 2222. An air outlet adjustment unit 2223 is installed inside the flared opening 2222. The air outlet adjustment unit 2223 includes a screw rod 2224 and an adjustment cone 2225 sleeved on the screw rod 2224. The screw rod 2224 is fixedly connected to the flared opening 2222 through a screw rod bracket 2225. The adjustment cone 2225 can move up and down along the screw rod 2224 to adjust the size and angle of the air outlet channel. Generally, a fixing nut is also sleeved on the screw rod 2224 to fix the position of the adjustment cone 2225.

[0043] The working process of the present utility model is as follows: The air conditioning device supplies air, which sequentially enters the box body 221 through the air inlet 212 and the telescopic hose 211. The air-conditioned air is mixed with the water mist generated by the spray humidifier in the box body 221 and then sprayed out from the flared opening 2222 of the branch pipe to humidify the square cabin at a constant temperature. The reduction motor 1211 rotates intermittently forward and backward, and pulls the box body 221 to reciprocate along the track 111 through the steel wire rope 122. The flared opening 2222 discharges the air at a constant temperature and high humidity at different positions in the square cabin. By changing the position of the adjustment cone 2225, the air volume and air direction of the flared opening 2222 are adjusted, so that the temperature and humidity in the entire cabin are uniform.
