Description

Technical Field

[0001] This application relates to the field of livestock farm sheds, specifically to a small window adjustment track. Background Technology

[0002] Livestock sheds typically have a row of ventilation windows installed at the top of the walls, with corresponding openings through the walls. During shed maintenance, when ventilation is needed, workers must set up ladders and manually open the windows. Because there are many windows, opening all of them requires repeated movement of the ladder and climbing to do so. Closing all windows requires repeating this process, resulting in long maintenance times and low efficiency. Summary of the Invention

[0003] The main purpose of this application is to improve the efficiency of maintaining livestock farm sheds.

[0004] To achieve the above objectives, this application provides a small window debugging track, employing the following technical solution:

[0005] A small window adjustment track is installed in a breeding farm shed. The breeding farm shed includes a wall, and a row of multiple window openings are opened at the top of the wall. A ventilation window is hinged to the top surface of the window opening. The small window adjustment track includes a push rod hinged to the window frame of the ventilation window. The end of the push rod away from the ventilation window is downward and tilted in a direction away from the ventilation window.

[0006] A slider is hinged to the end of the push rod away from the ventilation window. The slider is slidably connected to the bottom surface of the window opening, and the sliding direction of the slider is set along the depth direction of the window opening. A limit spring is connected to the slider. The end of the limit spring away from the slider is fixed to the bottom surface of the window opening, and the extension and retraction direction of the limit spring is the same as the sliding direction of the slider.

[0007] The small window debugging track also includes a drive component that drives the slider to slide.

[0008] By adopting the above technical solution, in the initial state, the limiting spring, slider, and push rod work together to keep the ventilation window closed. When maintenance of the farm shed is required, the operator controls the drive component to move the slider closer to the ventilation window. The slider's movement drives the push rod, simultaneously deforming the limiting spring. The push rod's movement pushes the ventilation window to rotate and open. When the ventilation window rotates to the appropriate angle, the operator controls the drive component to stop, keeping the ventilation window in its current state. When closing the ventilation window is required, the operator controls the drive component to reset, and the limiting spring returns to its original deformation, pushing the slider and push rod to move. The push rod moves to its initial position, causing the ventilation window to rotate and close. When the limiting spring returns to its initial state, the ventilation window is closed. This reduces the need for operators to repeatedly climb ladders when opening and closing the ventilation window, shortening the time required for farm shed maintenance and thus improving maintenance efficiency.

[0009] Optionally, the number of push rods is at least two, all push rods are distributed along the length direction of the ventilation window, and all sliders are fixedly connected to a connecting rod with a rectangular cross-section, the length direction of the connecting rod being consistent with the length direction of the ventilation window;

[0010] A drive rod is slidably inserted into the connecting rod, and a return spring is connected to one side wall of the drive rod. The length direction of the return spring is set along the length direction of the connecting rod, and the end of the return spring away from the drive rod is fixed to the side wall corresponding to the window frame.

[0011] The drive rod is hinged to a hinge rod at one end near the ventilation window, and the hinge rod is hinged to the bottom surface of the window opening at the other end away from the drive rod, and the hinge rod is inclined.

[0012] The drive assembly also includes a power component that causes the drive rod to slide along the connecting rod. The hinge point between the hinge rod and the window opening is a1, the direction between the hinge rod and the drive rod is a2, and the forward direction of the drive rod is from a1 to a2.

[0013] By adopting the above technical solution, when the ventilation window needs to be opened, the operator controls the power component to work. The power component moves the drive rod forward, which in turn drives the hinge rod to rotate. The end of the hinge rod near the drive rod rotates towards the ventilation window, and also deforms the return spring. The rotation of the hinge rod drives the drive rod, connecting rod, slider, and push rod towards the ventilation window, thereby causing the push rod to push the ventilation window to rotate and open. When the ventilation window needs to be closed, the power component is controlled to reset. At the same time, the return spring restores its deformation and moves the drive rod to its initial position. The limit spring also restores its deformation. The restoration of the limit spring causes the slider, push rod, connecting rod, and drive rod to rotate away from the ventilation window, causing the ventilation window to rotate and close. Simultaneously, the movement of the connecting rod and drive rod also causes the hinge rod to rotate and reset. When the power component moves to its initial position, the limit spring and the return spring also return to their initial state. At this time, the ventilation window is closed.

[0014] Optionally, the power component includes a track installed on the ground, the length direction of the track being consistent with the arrangement direction of a row of ventilation windows, a power column corresponding to the drive rod being slidably inserted in the track, the cross-section of the power column being rectangular, a lead screw being rotatably connected in the track, the lead screw passing through all the power columns and threadedly engaging with the power columns, and the power component also includes a motor for driving the lead screw to rotate.

[0015] By adopting the above technical solution, when the drive rod needs to move forward, the control motor works, the output shaft of the motor drives the lead screw to rotate, the lead screw cooperates with the rail, and the power column pushes the drive rod forward; when the drive rod needs to move and reset, the control motor works, the output shaft of the motor drives the lead screw to rotate in the opposite direction, the lead screw cooperates with the rail, and the power column moves and resets, while the limit spring and the reset spring restore their deformation, thereby moving and resetting the drive rod.

[0016] Optionally, the small window debugging track includes a control component for controlling the operation of the power component, and the control component is set in a one-to-one correspondence with the drive rod.

[0017] By adopting the above technical solution, operators can control the power components through the control components, thus shortening the time required to maintain the breeding farm sheds.

[0018] Optionally, the control assembly includes a sensing plate fixedly connected to the lower surface of the drive rod. The sensing plate is made of magnetic material. The control assembly also includes a mounting plate fixedly connected to the wall. The mounting plate is located on one side of the drive rod in the forward direction and is close to the window opening.

[0019] A proximity sensor is mounted on the side of the mounting plate near the drive rod. An electromagnet is also mounted on the side wall of the mounting plate where the proximity sensor is mounted. The electromagnet is close to the wall. The control assembly also includes a controller, which is electrically connected to the proximity sensor, the power unit, and the electromagnet.

[0020] By adopting the above technical solution, in the initial state, the sensing plate is outside the detection range of the proximity sensor. As the drive rod moves forward, it drives the sensing plate to move closer to the proximity sensor. When the sensing plate moves into the detection range of the proximity sensor, the proximity sensor transmits a signal to the controller. The controller controls the electromagnet to turn on the power, and the electromagnet attracts the sensing plate, causing it to move closer to the wall. The movement of the sensing plate drives the drive rod, connecting rod, and push rod to move further, thereby causing the ventilation window to continue to rotate and open. When the sensing plate contacts the electromagnet, the electromagnet attracts and fixes the sensing plate, thereby keeping the sensing plate, drive rod, connecting rod, slider, and push rod in their current positions, and keeping the ventilation window open.

[0021] At this time, the controller controls the movement and reset of the power components. When it is necessary to close the ventilation window, the controller disconnects the power to the electromagnet, causing it to lose its magnetism. The reset spring and limit spring then return to their original deformation, thereby resetting the drive rod, sensing plate, connecting rod, and the drive rod itself. Simultaneously, the ventilation window rotates to close. When both the limit spring and the reset spring return to their initial state, the ventilation window is closed. This reduces the need to wait for the power components to reset when closing the ventilation window, thus shortening the time required to close the ventilation window.

[0022] Optionally, a sliding rod is connected to the electromagnet, the sliding rod passes through the mounting plate and is slidably inserted into the mounting plate, the sliding direction of the sliding rod is set along the depth direction of the window opening, a hydraulic cylinder is installed on the mounting plate, the length direction of the hydraulic cylinder is also set along the depth direction of the window opening, and the extension rod of the hydraulic cylinder is fixed to the sliding rod.

[0023] By adopting the above technical solution, the operator can adjust the position of the electromagnet by controlling the hydraulic cylinder, and by adjusting the position of the electromagnet, the operator can control the opening angle of the ventilation window, so that the operator can control the opening angle of the ventilation window according to the actual situation.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. By setting up ventilation windows, push rods, sliders, limit springs, and drive components, the need for operators to repeatedly build ladders when opening and closing ventilation windows is reduced, thus shortening the time required to maintain the farm shed and improving the efficiency of farm shed maintenance;

[0026] 2. By setting a hinge rod, a drive rod, a return spring, and a power component, the drive rod can be moved or reset;

[0027] 3. By setting up an induction plate, proximity sensor, mounting plate, electromagnet, and controller, the need to wait for the power components to reset when closing the ventilation window is reduced, thus shortening the time required to close the ventilation window.

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application; however, this application may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0036] This application discloses a small window debugging track. (Refer to...) Figure 1 and Figure 2 It is set up in the breeding farm shed, which includes a wall 1, on which a row of windows 11 are opened. There are multiple windows 11, and each window 11 has a ventilation window 2 hinged to its top surface; refer to Figure 2 and Figure 3 A push rod 3 is hinged to the window frame of the ventilation window 2. In this embodiment, each ventilation window 2 corresponds to two push rods 3. The two push rods 3 are distributed on both sides of the ventilation window 2, and the end of the push rod 3 away from the ventilation window 2 is tilted downward.

[0037] A T-shaped slider 31 is hinged to the end of the push rod 3 away from the ventilation window 2. A groove 12 corresponding to the slider 31 is opened on the bottom surface of the window opening 11. The length direction of the groove 12 is set along the depth direction of the window opening 11. The slider 31 is slidably inserted into the corresponding groove 12. A limit spring 4 is fixedly connected to the slider 31. The end of the limit spring 4 away from the slider 31 is fixedly connected to the groove wall of the groove 12 near the ventilation window 2. When the limit spring 4 is not subjected to external force, the limit spring 4 keeps the slider 31 at the end of the groove 12 away from the ventilation window 2. The limit spring 4, the slider 31 and the push rod 3 cooperate to close the ventilation window 2.

[0038] Reference Figure 3 and Figure 4A rectangular connecting rod 5 is provided between the two sliders 31. Both ends of the connecting rod 5 are fixed to the corresponding sliders 31. The small window adjustment track 641 also includes a driving component 6 that drives the connecting rod 5 to move along the depth of the window frame. The driving component 6 includes a driving rod 61 that corresponds to the connecting rod 5. The driving rod 61 is set horizontally and its length direction is set along the depth direction of the window opening 11. The connecting rod 5 passes through the corresponding driving rod 61 and is slidably inserted into the driving rod 61.

[0039] A return spring 62 is fixedly connected to the drive rod 61. The return spring 62 is sleeved on the connecting rod 5. The end of the return spring 62 away from the drive rod 61 is fixed to the corresponding slider 31. A hinge rod 63 is hinged to the end of the drive rod 61 near the ventilation window 2. The hinge rod 63 is inclined. The end of the hinge rod 63 away from the drive rod 61 is hinged to the bottom surface of the window opening 11. The hinge point between the hinge rod 63 and the bottom surface of the window opening 11 is a1, and the hinge point between the hinge rod 63 and the drive rod 61 is a2.

[0040] Reference Figure 2 and Figure 4 The drive assembly 6 also includes a power component 64 for moving the drive rod 61, with the drive rod 61 moving from a1 to a2. The power component 64 includes a track 641 mounted on the ground, the length of which is aligned with the arrangement of a row of ventilation windows 2, and the track 641 is close to the wall 1. A rectangular cross-section power column 642 is slidably inserted into the track 641, with each power column 642 corresponding to a drive rod 61. The power column 642 is located on the side of the drive rod 61 near the hinge point a1, and the upper surface of the power column 642 is not lower than the lower surface of the drive rod 61. The power component 64 also includes a lead screw 643 rotatably connected in the track 641, the lead screw 643 passing through each power column 642 and threadedly engaging with the power column 642. A motor 644 is mounted at one end of the track 641, and the output shaft of the motor 644 is coaxial with and fixedly connected to the lead screw 643.

[0041] In the initial state, the return spring 62 is not subjected to external force and limits the drive rod 61. At this time, the power column 642 is in contact with the drive rod 61, and the hinge rod 63 cooperates with the return spring 62 to make the connecting rod 5 and the slider 31 located at the edge of the window opening 11. The slider 31, the push rod 3 and the limiting spring 4 cooperate to make the ventilation window 2 closed. When it is necessary to open the ventilation window 2, the operator controls the motor 644 to work. The motor 644 makes the lead screw 643 rotate, and the lead screw 643 drives the power column 642 to move. The forward direction of the power column 642 is from the hinge point a1 to the hinge point a2.

[0042] The movement of the power column 642 pushes the drive rod 61 to move. Simultaneously, the drive rod 61 deforms the return spring 62. The drive rod 61 also moves one end of the hinge rod 63, causing the end of the hinge rod 63 near the connecting rod 5 to rotate towards the ventilation window 2. This causes the hinge rod 63 to pull the drive rod 61, connecting rod 5, and slider 31 towards the ventilation window 2. The slider 31 then moves the push rod 3, causing it to push the lower side of the ventilation window 2 towards the outside of the shed, thus opening the ventilation window 2. When the ventilation window 2 is in position, the operator stops the motor 644, allowing the ventilation window 2 to maintain its current angle. This reduces the need for operators to repeatedly set up ladders, shortens the time required to open the ventilation window 2, and consequently reduces the time required to maintain the shed, improving maintenance efficiency.

[0043] Reference Figure 2 , Figure 3 and Figure 5 The wall 1 is also equipped with control components 7 corresponding to the drive rod 61. The control components 7 include a mounting plate 71 fixed on the wall 1. The mounting plate 71 is adjacent to the window opening 11. In this application, the forward direction of the drive rod 61 is defined as the front of the drive rod 61. The mounting plate 71 is located in front of the drive rod 61. A proximity sensor 72 is fixedly connected to the side wall of the mounting plate 71 near the drive plate. A sensing plate 73 perpendicular to the drive rod 61 is fixedly connected to the lower surface of the drive rod 61. The sensing plate 73 is made of magnetic material and is located outside the window opening 11. The projections of the sensing plate 73 and the proximity sensor 72 in the horizontal direction overlap.

[0044] An electromagnet 74 is also connected to the side wall of the mounting plate 71 near the drive rod 61. The electromagnet 74 is located below the proximity sensor 72. A sliding rod 75 is fixedly connected to the electromagnet 74. The mounting plate 71 has a sliding groove 711 for the sliding rod 75 to slide into. The length direction of the sliding groove 711 is set along the depth direction of the window opening 11. The sliding rod 75 is slidably inserted into the sliding groove 711, and the end of the sliding rod 75 away from the electromagnet 74 is located on the side of the mounting plate 71 away from the electromagnet 74. A hydraulic cylinder 76 is installed on the side wall of the mounting plate 71 away from the electromagnet 74. The axis of the hydraulic cylinder 76 is set along the depth direction of the window opening 11. The telescopic rod of the hydraulic cylinder 76 is fixed to the end of the sliding rod 75 away from the electromagnet 74. The control assembly 7 also includes a controller, which is not shown in the figure. The controller is electrically connected to the power supply of the electromagnet 74, the proximity sensor 72, and the motor 644.

[0045] Initially, there is a distance between the sensing plate 73 and the proximity sensor 72, and the sensing plate 73 is outside the detection range of the proximity sensor 72. As the drive rod 61 moves forward, the drive rod 61 drives the sensing plate 73 forward and towards the wall 1. When the sensing plate 73 moves into the detection range of the proximity sensor 72, the proximity sensor 72 transmits a signal to the controller. At this time, the controller controls the power supply of the electromagnet 74 to be turned on, so that the electromagnet 74 attracts the sensing plate 73, causing the sensing plate 73 to move towards the wall 1 until the sensing plate 73 contacts the electromagnet 74.

[0046] As the induction plate 73 moves closer to the electromagnet 74, it drives the drive rod 61 to move as well. Simultaneously, the drive rod 61 drives the hinge rod 63 to rotate, causing the hinge rod 63 to drive the drive rod 61, connecting rod 5, push rod 3, and induction plate 73 to move closer to the ventilation window 2. This causes the push rod 3 to further push the ventilation window 2 to rotate. When the induction plate 73 moves to contact the electromagnet 74, the ventilation window 2 stops rotating and maintains its current position. At this point, the angle of the ventilation window 2 is the final opening angle. The operator can adjust the position of the electromagnet 74 through the hydraulic cylinder 76. By adjusting the position of the electromagnet 74, the opening angle of the ventilation window 2 can be changed. The operator can select the position of the electromagnet 74 according to the actual situation to determine the opening angle of the ventilation window 2.

[0047] When the induction plate 73 contacts the electromagnet 74, the operator controls the motor 644 to work through the controller, causing the output shaft of the motor 644 and the lead screw 643 to rotate in the opposite direction, and the power column 642 to move to the initial position; when ventilation ends and the ventilation window 2 needs to be closed, the operator controls the power supply of the electromagnet 74 to be disconnected through the controller. At this time, the electromagnet 74 loses its magnetism, releases the fixation of the induction plate 73, and the reset spring 62 and the limit spring 4 both return to their original deformation.

[0048] The return spring 62 restores its deformation and pushes the drive rod 61 to move closer to the power column 642 to reset. The drive rod 61 moves and drives the corresponding end of the hinge rod 63 to move, causing the hinge rod 63 to rotate. At the same time, the limit spring 4 also restores its deformation and pushes the slider 31, connecting rod 5, drive rod 61 and sensing plate 73 to move away from the ventilation window 2. The slider 31 drives the ventilation window 2 to rotate and close through the push rod 3. When the return spring 62 and the limit spring 4 both return to their initial state, the ventilation window 2 also rotates to close, reducing the need to wait for the power column 642 to move and reset when closing the ventilation window 2, thereby reducing the time required to close the ventilation window 2.

[0049] The implementation principle of a small window adjustment track in this application embodiment is as follows: When maintaining the breeding farm shed, the operator determines the position of the electromagnet 74 according to the actual situation and controls the hydraulic cylinder 76 to move the electromagnet 74 to the predetermined position. Then, the controller controls the motor 644 to work, so that the power column 642 pushes the drive rod 61 forward. At the same time, the drive rod 61 drives the hinge rod 63 to rotate, so that the hinge rod 63 pulls the drive rod 61, the connecting rod 5, the sensing plate 73 and the push rod 3 to move. The push rod 3 moves and pushes the ventilation window 2 to rotate and open. When the sensing plate 73 moves into the detection range of the proximity sensor 72, the proximity sensor 72 transmits the signal to the controller. The controller controls the power of the electromagnet 74 to turn on. The electromagnet 74 attracts and fixes the sensing plate 73. While the sensing plate 73 moves, it also causes the ventilation window 2 to rotate and open further.

[0050] During ventilation, the operator controls the output shaft of motor 644 to rotate in the opposite direction via the controller, causing the power column 642 to move and reset. After ventilation is completed, the operator controls the power supply of electromagnet 74 to disconnect via the controller. At this time, both the reset spring 62 and the limit spring 4 return to their original deformation, causing the ventilation window 2 to rotate and close. When both the reset spring 62 and the limit spring 4 return to their initial state, the ventilation window 2 is in the closed state.

[0051] Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of this application.
