TECHNICAL FIELD

[0001] The utility model relates to the technical field of breeding, especially to an air inlet structure. BACKGROUND

[0002] With the rapid development of intensive breeding technology, the use of breeding equipment becomes increasingly frequent. In the ventilation system of the breeding farm, the fan is responsible for regulating the air circulation in the shed. However, in the actual operation process, the cooperation between the louvers and the frame will become no longer tight due to factors such as wear, aging or deformation. This non-tight condition will cause different degrees of air leakage, that is, external air directly enters the breeding shed without sufficient regulation, or the air in the shed is not effectively discharged and short-circuits back. Air leakage and ventilation short-circuit cause the temperature at the rear end of the breeding shed to decrease, and the negative pressure is abnormal. SUMMARY

[0003] Therefore, in order to solve the above problems, the utility model provides an air inlet structure to increase the temperature at the rear end of the shed by 2-3℃, reduce the ventilation short-circuit condition, and form stable negative pressure after the temperature decreases in autumn and winter.

Moreover, the terms "comprises", "comprising", or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus.

[0042] As described in the background, in actual operation, the cooperation between the louvers and between the louvers and the frame of the fan will become loose due to factors such as wear, aging or deformation. This loose cooperation will cause different degrees of air leakage, that is, external air directly enters the breeding house without sufficient adjustment, or the air in the house short-circuits and returns without being effectively discharged. Air leakage and ventilation short-circuit cause the temperature at the rear end of the breeding house to decrease, and the ventilation negative pressure to be abnormal.

[0044] Therefore, in order to solve the above technical problems of the prior art, the present embodiment provides an air inlet structure to increase the temperature at the rear end of the house by 2-3℃, reduce the ventilation short-circuit condition, and form a stable negative pressure after the temperature decreases in the autumn and winter seasons.

[0045] As shown in Figure 1 , the air inlet structure comprises:

[0046] an air inlet portion 30 fixed on the fixed portion 20, and a connecting portion 21 provided on each side of the air inlet portion and fixed on the fixed portion;

[0048] The embodiment forms a block by sleeving the windproof sleeve on the air inlet part and fixing the windproof sleeve by binding the connecting rope on the connecting part, so that the air inlet part is blocked, external cold air is prevented from flowing into the rear end of the henhouse from the air inlet, and compared with the henhouse with the traditional air inlet structure, the temperature of the rear end of the henhouse is increased by 2-3℃, the ventilation short circuit condition is reduced, and stable negative pressure is formed.

[0049] In the embodiment, as shown in Figure 3 , the windproof sleeve further comprises a loop belt 13, which is arranged along the edge of the windproof sleeve body and is relatively fixed with the windproof sleeve body.

[0050] The windproof sleeve further comprises a binding rope 12, which is inserted from one end of the loop belt and is taken out from the other end, and both ends of the binding rope are outside the loop belt.

[0051] The embodiment tightens the loop belt by pulling the end of the binding rope, and then knots the binding rope after being tightened, so as to reduce the gap between the edge of the windproof sleeve and the outside of the air inlet part, and prevent air leakage of the edge.

[0052] As shown in Figure 1 , the connecting part can be an L-shaped block. The embodiment can use an "L"-shaped 2mm rear iron plate as the fan sleeve connecting part, and then a 30-40cm long belt is pre-made on the fan sleeve for binding on the fixing part Figure 2 , and the binding rope is pulled tight and knotted after being fixed to prevent air leakage of the edge.

[0057] The embodiment drives the wind guide plate to rotate by pushing the push rod to rotate around the end connected to the pivot shaft, so as to realize the opening and closing of the air duct.

[0058] In the embodiment, the adjacent push rods are connected through a first connecting rod 33. Specifically, the two ends of the first connecting rod are respectively pivotally connected to the two groups of push rods away from the pivot shaft end.

[0059] Through the transmission of the first connecting rod, when one group of push rods is pushed, the linkage with the push rods can be realized.

[0060] Example 2:
