[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Depend on Figure 1-3 The automatic ventilation device for a mesh-frame meat duck breeding duck shed shown in the figure comprises a top frame 1, four legs 2 are fixedly connected to the sides of the bottom surface of the top frame 1, a shielding mechanism is arranged between two adjacent legs 2, two groups of shielding mechanisms are arranged opposite to each other, the legs 2 at one end of the two shielding mechanisms are covered by a door curtain (not shown in the drawings), which is the prior art and will not be described in detail here; the shielding mechanism comprises a shielding component, the shielding components are respectively arranged on the opposite sides of the two legs 2 on the same side, a driving unit is embedded in the legs 2, a first roller 3 and a second roller 4 are arranged between the two legs 2 on the same side, a windproof component is transmission-connected between the first roller 3 and the second roller 4, the windproof component comprises a windproof cloth 14, connecting end plates 15 are respectively fixedly connected to the two ends of the windproof cloth 14, and a number of elastic rubber strips 16 are fixedly connected at equal intervals between the two connecting end plates 15. The first roller 3 and the second roller 4 are respectively fixedly connected to the driving units in the two supporting legs 2 on the same side; the bottom ends of the driving units in the two supporting legs 2 on the same side are also fixedly connected with a barrier assembly, and the driving unit can drive the first roller 3 to rotate, and the driving unit lifts and lowers the second roller 4 through the barrier assembly; the top surface of the top frame 1 is fixedly connected with an upper ventilation unit.

[0024] Furthermore, the windproof cloth 14 is a transparent high-toughness plastic cloth.

[0025] Furthermore, the first roller 3 and the second roller 4 are respectively made of aluminum alloy, which can reduce the overall weight and utilize the deadweight of the second roller 4 to stretch and flatten the windproof cloth 14.

[0026] The present invention utilizes a double-layer shielding mechanism to keep the temperature in the duck shed warm, thereby reducing the heating investment for meat duck farming in winter. In order to keep the air in the duck shed fresh and prevent the meat ducks from getting infectious diseases due to grouping, the first roller 3 can be driven by the driving unit to rise to achieve air exchange in the duck shed, and the synchronous upper ventilation unit cooperates with the first roller 3 to achieve rapid air exchange.

[0027] A further optimization scheme is that the two legs 2 on the same side are respectively provided with slide grooves on opposite sides; the driving unit includes a rotating motor 7 and a lifting motor 8, the rotating motor 7 and the lifting motor 8 are respectively fixedly installed in the slide groove, the rotating motor 7 and the lifting motor are both arranged at the top of the slide groove, the rotating motor 7 is arranged above the lifting motor 8, and the rotating motor 7 is transmission-connected to one end of the first roller 3; the lifting motor 8 is transmission-connected to a screw rod 9, and a first slider 10 and a second slider 11 are respectively arranged at the bottom of the screw rod 9, the first slider 10 is sleeved on the outside of the screw rod 9 and is slidingly connected to the slide groove, a gap is arranged between the first slider 10 and the outer side of the screw 9, the second slider 11 is screwed with the screw 9 and is slidingly connected to the slide groove, and one side of the first slider 10 is fixedly connected to one end of the second roller 4; the side of the second slider 11 is fixedly connected to the barrier assembly, and the second slider 11 is arranged below the first slider 10, and the first roller 3 is driven by the rotating motor 7 to realize the driving of the windproof cloth 14, and the second roller 4 rotates with the rotation of the windproof cloth 14. The lifting motor 8 can drive the screw rod 9 to lift the second roller 4 along the axis of the supporting leg 2 to achieve wind protection for the duck shed.

[0028] A further optimized solution is that the blocking component includes a blocking shaft 12, both ends of the blocking shaft 12 are respectively fixedly connected to the side of the second slider 11, and a blocking plate 13 is fixedly connected to the side of the blocking shaft 12, and the blocking plate 13 is a mesh plate or a grating plate. The blocking plate 13 is arranged below the top frame 1, that is, in the inner cavity of the duck shed, which can avoid obstructing the inflow of fresh air when the first roller 3 is ventilated and breathable, and can also prevent the meat ducks from pecking the windproof cloth 14 when they are active, thereby increasing the service life of the windproof cloth 14.

[0029] Further optimization scheme, the shielding assembly includes a first shielding plate 5 and a second shielding plate 6, the top of the first shielding plate 5 is fixedly connected to a side of the top frame 1, the first shielding plate 5 can block the gap between the first roller 3 and the top frame 1, and improve the heat preservation effect, the two ends of the second shielding plate 6 are respectively fixedly connected to the two legs 2 at the two ends of the first roller 3, the first shielding plate 5 and the second shielding plate 6 are both flexible and transparent resin plates, the bottom of the first shielding plate 5 is set on the upper part of the legs 2, the second shielding plate 6 is set at the middle of the side of the two legs 2 at the two ends of the first roller 3 away from the first shielding plate 5, the second shielding plate 6 and the rubber strip 16 are set at the same height, and the second shielding plate 6 can completely block the gap between the two ends of the windproof cloth 14, so that the two layers of windproof cloth 14 form a greenhouse, and improve the utilization rate of solar energy. And when the first roller 3 is lifted to release the wind, it will not block the air inlet.

[0030] To further optimize the solution, the two legs 2 at both ends of the first roller 3 are respectively fixed with a guide plate 17 on one side away from the connecting end plate 15, and one side of the guide plate 17 is in sliding contact with the windproof cloth 14. The guide plate 17 is a flexible rubber plate, which closes the gap between the windproof cloth 14 and the legs. It can also achieve that when the first roller 3 is lifted, the windproof cloth 14 is driven to fold and squeeze to avoid being blown by the external strong wind or even shaking randomly to cause damage.

[0031] Further optimization scheme, the upper ventilation unit includes a fixed shed 18 and a mobile shed, the bottom surface of the fixed shed 18 is fixedly connected to the top surface of the top frame 1, one end of the bottom surface of the mobile shed is rotatably connected to the top surface of the top frame 1, the other end of the mobile shed is arranged in the inner cavity of the fixed shed 18, the two opposite sides of the mobile shed are respectively slidably connected to the two opposite sides of the fixed shed 18, the top surface of the inner cavity of the fixed shed 18 is rotatably connected with a plurality of electric cylinders 21, and the electric cylinders 21 are rotatably connected to the top frame 1 through the support beam; the temperature sensor 22 is fixedly installed on the bottom surface of the support beam, and the support beam is provided with a plurality of beams, which are respectively fixedly connected to the opposite side walls of the top frame 1, and the top frame 1 is a square frame, which is the prior art and will not be described here. The top surface of the fixed shed 18 is fixedly connected and connected with a plurality of unpowered hoods 23. The hood 23 can actively extract the air in the duck shed from the gap between the fixed shed 18 and the mobile shed, thereby improving the ventilation efficiency. At the same time, the electric cylinder 21 can expand and reduce the gap between the fixed shed 18 and the mobile shed, thereby realizing the adjustment of the ventilation rate. The movable shed includes an arc plate 19 and a fan plate 20 fixed to both ends of the arc plate 19, one side of the fan plate 20 is in sliding contact with the two fan-shaped side surfaces of the inner cavity of the fixed shed 18, one end of the arc plate 19 is rotatably connected to the top surface of the top frame 1, the other end of the arc plate 19 is arranged in the inner cavity of the fixed shed 18 and is detachably connected to the top surface of the inner cavity of the fixed shed 18, and the bottom surface of the other end of the arc plate 19 is rotatably connected to the top end of the electric cylinder 21.

[0032] Further, the rotating motor 7, the lifting motor 8 and the electric cylinder 22 are electrically connected to the controller respectively;

[0033] Furthermore, the controller is a PLC controller, which integrates a remote communication module and can achieve remote control of the present invention through a remote terminal. This is a prior art and will not be described in detail here.

[0034] The working process of this embodiment is as follows:

[0035] The meat ducks are placed in the duck shed. In the initial state, the shielding mechanism closes the grid formed by the top frame 1 and the legs 2, and the gap between the arc plate 19 and the fixed shed 18 is adjusted to zero, reducing the exchange of air, and the top surface of the arc plate 19 blocks the air inlet of the hood 23, thereby increasing the heating rate in the duck shed. During the breeding process of several meat ducks, due to continuous activities, the temperature in the grid gradually rises, and the temperature sensor 22 located on the bottom surface of the top frame 1 will try to detect the temperature value and transmit the value to the controller. The controller will set a limit on the temperature value. When the upper limit is reached, the controller will first control the rotating motor 7 to rotate the rubber strip 16 to the side of the second roller 4. At this time, the outside air will enter the grid through the gap between the rubber strips 16, and then control the electric cylinder 22 to retreat, drive the arc plate 19, and increase the gap between the arc plate 19 and the top surface of the inner cavity of the fixed shed 18. At this time, an air convection is formed inside and outside the duck shed, which is conducive to the rapid exchange of air and the reduction of temperature.

[0036] When the purpose of rapid air exchange cannot be achieved through the gap of the rubber strip 16, the controller controls the lifting motor 8 to rotate, and the rotation of the lifting motor 8 drives the fixed screw 9 to rotate, and the screw 9 drives the second slider 11 to rise along the slide slot, that is, drives the blocking shaft 12 to rise, and the rising blocking shaft 12 will abut against the rubber strip 16 on the second roller 4, and then push the second roller 4 to drive the connecting end plate 15 and the windproof cloth 14 to rise in turn, so as to fully open the side of the grid and improve the ventilation efficiency. On the contrary, it will operate in the opposite direction, using the sunlight to achieve the accumulation and increase of the temperature in the duck shed.

[0037] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0038] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
