Description

Technical Field

[0001] The utility model relates to the technical field of poultry breeding, in particular to a ventilation device. Background Art

[0002] In poultry farming, ventilation devices are very important equipment. A good ventilation system can effectively improve the air quality in the breeding house, reduce the accumulation of ammonia and carbon dioxide, reduce the spread of pathogenic microorganisms, and improve the growth and health of poultry.

[0003] At present, some poultry breeding areas do not have ventilation devices, only natural ventilation, while other parts are equipped with ventilation devices, but the vents are always open. When the wind speed for outward ventilation is low, external debris will enter through the open vents. When the ventilation device is not working, the temperature of the breeding area will quickly dissipate outward through the open vents, destroying the poultry breeding environment and being unfavorable for the growth and development of poultry. Therefore, we propose a ventilation device. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that the vents are always in an open state. When the wind speed for outward ventilation is low, external debris will enter through the open vents. When the ventilation device is not working, the temperature of the breeding area will quickly dissipate outward through the open vents, destroying the poultry breeding environment and being detrimental to the growth and development of poultry. Therefore, we propose a ventilation device.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a ventilation device, including a grille window, one side of the grille window is fixedly connected to a limit frame, the other side of the limit frame is fixedly connected to a ventilation mechanism, and the other side of the ventilation mechanism is provided with an adjustable opening mechanism, the adjustable opening mechanism includes a side cover, a sealing strip, a cylinder shell, a mounting plate, a connecting ring, a lever, a sleeve, a side column, a central axis, a limit pin and a sleeve shell, the outer side of the sleeve shell is provided with two groups of vertical grooves and two groups of arc grooves, the limit pin passes through and is fixedly connected to one end of the central axis, the two ends of the limit pin are respectively slidably connected to the two groups of the arc grooves, the other end of the central axis passes through the middle of the sleeve and the mounting plate, and is fixedly connected to the lever, the two groups of the side columns are respectively fixedly connected to the two sides of one end of the sleeve, and the two groups of the side columns are respectively slidably connected to the two groups of the vertical grooves.

[0006] Furthermore, a side groove is opened in the middle of the connecting ring, the shift rod is located inside the side groove, and the mounting plate is fixedly mounted in the middle of the connecting ring.

[0007] Furthermore, the cylindrical shell and the sleeve are fixedly connected to the same side of the mounting plate, and the cylindrical shell is located outside the sleeve.

[0008] Furthermore, the sealing strip is clamped on one side of the cylinder shell, and the middle part of one side of the side cover is fixedly connected to the other end of the sleeve shell.

[0009] Furthermore, a circular cylinder is threadedly connected to the middle of the connecting ring, and a driving motor is fixedly connected to the inner side of the circular cylinder.

[0010] Furthermore, a fan blade group is fixedly mounted on the output end of the driving motor, and the fan blade group is located in the middle of the circular cylinder.

[0011] Furthermore, a mounting frame is fixedly connected to the other side of the circular cylinder, a connecting ring frame is fixedly connected to the interior of the mounting frame, and the connecting ring frame abuts against the outer side of the driving motor.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, the size of the gap is controlled by controlling the angle of the lever, and the size of the gap is proportional to the wind speed, that is, the greater the wind speed, the larger the ventilation gap, and the smaller the wind speed, the smaller the ventilation gap. This avoids the situation where the excessively large ventilating openings of the traditional ventilation device affect the internal environment of the breeding house when there is no ventilation or the ventilation wind speed is low, thereby improving the practicality of the ventilation device and better improving the air quality inside the breeding house.

[0014] 2. In the utility model, by controlling the start of the driving motor, the driving motor drives the fan blade group to rotate inside the circular cylinder to generate an outward directional wind speed, so that the air inside the breeding house passes through the lattice window into the limit frame. The middle part of the lattice window is opened as a downward inclined opening, which is convenient for the air inside the breeding house to enter and also has a shading effect. The air inside the breeding house then passes through the mounting frame, the connecting ring frame, the circular cylinder and the middle area of ​​the adjustable opening mechanism in sequence, and finally ventilates outward from the gap to improve the air quality inside the breeding house.

[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 1 - Figure 4 As shown, the utility model provides a ventilation device, including a grille window 1, one side of the grille window 1 is fixedly connected to a limit frame 11, the other side of the limit frame 11 is fixedly connected to a ventilation mechanism 2, the other side of the ventilation mechanism 2 is provided with an adjustable opening mechanism 3, the adjustable opening mechanism 3 includes a side cover 31, a sealing strip 32, a cylinder shell 33, a mounting plate 34, a connecting ring 35, a lever 37, a sleeve 38, a side column 39, a central axis 310, a limit pin 311 and a sleeve shell 313, the outer side of the sleeve shell 313 is provided with two groups of vertical grooves 312 and two groups of arc grooves 314, the limit pin 311 penetrates and is fixedly connected to one end of the central axis 310, and the two ends of the limit pin 311 slide respectively. The two sets of arc grooves 314 are connected, the other end of the central axis 310 passes through the middle of the sleeve 38 and the mounting plate 34, and is fixedly connected to the lever 37. The two sets of side columns 39 are respectively fixedly connected to the two sides of one end of the sleeve 38, and the two sets of side columns 39 are respectively slidably connected to the two sets of vertical grooves 312. A side groove 36 is opened in the middle of the connecting ring 35, and the lever 37 is located on the inner side of the side groove 36. The mounting plate 34 is fixedly installed in the middle of the connecting ring 35. The cylinder shell 33 and the sleeve 38 are fixedly connected on the same side of the mounting plate 34, and the cylinder shell 33 is located on the outside of the sleeve 38. The sealing strip 32 is clamped on one side of the cylinder shell 33, and the middle of one side of the side cover 31 is fixedly connected to the other end of the sleeve shell 313.

[0023] The effect achieved by the entire embodiment 1 is that by bending the lever 37, the lever 37 is made to move in an arc around one end in the side groove 36, and the lever 37 drives the central axis 310 to rotate in the middle of the mounting plate 34 and the sleeve 38, thereby driving the two ends of the limit pin 311 to rotate in the two groups of arc grooves 314. Since the arc grooves 314 are inclined, and since the two groups of side columns 39 are respectively embedded in the two groups of vertical grooves 312, the sleeve 313 is restricted from rotating outside the sleeve 38. When the limit pin 311 rotates, a force is applied to the side wall of the arc groove 314. The component of this force pushes the sleeve shell 313 to move horizontally outward outside the sleeve 38, thereby pushing the side cover 31 to separate from the sealing strip 32, and a gap gradually appears between the side cover 31 and the cylinder shell 33. The size of the gap is controlled by controlling the angle of the lever 37. The size of the gap is proportional to the wind speed, that is, the greater the wind speed, the larger the ventilation gap, and the smaller the wind speed, the smaller the ventilation gap. This avoids the situation where the excessively large ventilating openings of the traditional ventilation device affect the internal environment of the breeding house when there is no ventilation or the ventilation wind speed is low, thereby improving the practicality of the ventilation device.

[0024] Embodiment 2, as Figure 1 - Figure 3 As shown, the difference between this embodiment and embodiment 1 is that a circular cylinder 24 is threadedly connected to the middle part of the connecting ring 35, a driving motor 23 is fixedly connected to the inner side of the circular cylinder 24, a fan blade group 25 is fixedly installed on the output end of the driving motor 23, and the fan blade group 25 is located in the middle part of the circular cylinder 24, and a mounting frame 21 is fixedly connected to the other side of the circular cylinder 24, and a connecting ring frame 22 is fixedly connected to the inside of the mounting frame 21, and the connecting ring frame 22 abuts against the outer side of the driving motor 23.

[0025] The effect achieved by the entire embodiment 2 is that by controlling the drive motor 23 to start, the drive motor 23 drives the fan blade group 25 to rotate inside the circular cylinder 24 to generate an outward directional wind speed, so that the air inside the breeding house passes through the lattice window 1 into the limit frame 11. The middle part of the lattice window 1 is opened as a downward inclined opening, which is convenient for the air inside the breeding house to enter and also has a shading effect. The air inside the breeding house then passes through the mounting frame 21, the connecting ring frame 22, the circular cylinder 24 and the middle area of ​​the adjustable opening mechanism 3 in turn, and finally ventilates outward from the gap to improve the air quality inside the breeding house.

[0026] Working principle: When the ventilation device is used, the entire device is installed at the ventilation position of the poultry breeding house, the grille window 1 is located inside the breeding house, and the adjustable opening mechanism 3 extends to the outside of the breeding house. When ventilation is needed, the lever 37 is moved to make an arc movement around one end in the side groove 36, and the lever 37 drives the central axis 310 to rotate in the middle of the mounting plate 34 and the sleeve 38, thereby driving the two ends of the limit pin 311 to rotate in the two groups of arc grooves 314. Since the arc grooves 314 are inclined, and since the two groups of side columns 39 are respectively embedded in the two groups of vertical grooves 312, the sleeve 313 is restricted from rotating on the outside of the sleeve 38. When the limit pin 311 rotates A force is applied to the side wall of the arc groove 314, and the component of the force pushes the sleeve shell 313 to move horizontally outward outside the sleeve 38, thereby pushing the side cover 31 to separate from the sealing strip 32, and a gap is gradually exposed between the side cover 31 and the cylinder shell 33. The size of the gap is controlled by controlling the angle of the lever 37, and the drive motor 23 is controlled to start. The drive motor 23 drives the fan blade group 25 to rotate inside the circular cylinder 24 to generate an outward directional wind speed, so that the air inside the breeding house passes through the grille window 1 into the limit frame 11, and passes through the mounting frame 21, the connecting ring frame 22, the circular cylinder 24 and the middle area of ​​the adjustable opening mechanism 3 in turn, and finally ventilates outward from the gap.

[0027] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
