Description

Technical Field

[0001] The utility model relates to agricultural production equipment, in particular to an opening and closing control system for a small window of an agricultural shed. Background Art

[0002] Large-scale agricultural development is an important development direction of modern agriculture, and agricultural site automation control is an important foundation for large-scale agricultural development. With the increase in labor costs, the Internet of Things transformation of agricultural sites will greatly reduce the investment of agricultural manpower and time, and improve the accuracy and agility of agricultural production. The following will take farm ventilation control as an example to briefly explain the important impact of agricultural site automation control on agricultural production.

[0003] Through ventilation adjustment in farms, the oxygen, temperature and humidity in farms can be scientifically controlled, so that animals can have a more scientific growth environment. Farms under large-scale agriculture often have a large number of windows, and the opening and closing tightness requirements of these windows are generally general. Regular opening and closing control of windows is of great significance to the adjustment of the internal environment of farms. However, the scheduled opening and closing of a large number of windows requires a lot of manpower and time. Therefore, some people apply remote IoT control technology to the opening and closing of windows. By installing an opening and closing motor or hydraulic cylinder on each window and connecting to the network, the opening and closing of the windows can be controlled from the background.

[0004] The above-mentioned remote IoT control can indeed greatly save a lot of labor and time. However, since the windows of the farms are often opened and closed synchronously, adding a control mechanism for each window obviously wastes materials and energy. Moreover, since multiple motors or hydraulic cylinders need to be controlled, the system stability is relatively weak. When the system fails, the corresponding maintenance workload is also large. Therefore, the existing window opening and closing control system of the farm needs to be further improved. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a small window opening and closing control system for a farm shed that can automatically open and close multiple windows at the same time. Through centralized control, the system construction cost can be reduced and the ventilation operation of the farm shed can be simplified.

[0006] In order to solve the above technical problems, the technical solution of the utility model is:

[0007] A control system for opening and closing small windows of an agricultural shed comprises at least two windows and a control motor for controlling the opening and closing of the windows, each of the windows being provided with a baffle for realizing the opening and closing of the window, the control motor being provided with a first output head and a second output head for synchronous output and opposite output directions, the windows being divided into two groups, a first group of windows and a second group of windows, the first output head controlling the connection to the first group of windows, and the second output head controlling the connection to the second group of windows.

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] Embodiment 1:

[0025] like Figure 1-3 As shown, the present embodiment discloses a control system for opening and closing small windows of a farm shed based on a push rod output, which includes at least two windows 1 and a control motor 3 for controlling the opening and closing of the windows, and each window 1 has a baffle 2 for realizing the opening and closing of the window. The present embodiment includes ten windows 1 to be controlled to be opened and closed and a control motor 3 for controlling the opening and closing of the windows. The ten windows 1 to be controlled to be opened and closed are all distributed on the same wall of the farm shed and the ten windows 1 are evenly distributed horizontally. The control motor 3 is placed below the center of the ten windows 1, that is, below the center between the fifth window and the sixth window. The windows 1 are divided into two groups, the first group of windows and the second group of windows. In the present embodiment, the first to fifth windows are the first group of windows, and the sixth to tenth windows are the second group of windows.

[0026] The baffles 2 of all windows 1 are usually in a normally closed state. When the control motor 3 realizes output, the baffles 2 are pulled to deviate from the original position, so that the baffles 2 are in an open state, and the opening and closing of the window 1 is realized by opening and closing the baffles 2. The baffles 2 of the window 1 can realize the opening and closing of the above-mentioned window 1 through different installation methods. In this embodiment, the baffles 2 open upward. Specifically, the baffles 2 are hinged to the inner wall of the window 1 through the bottom hinge 4. When the upper section of the baffle 2 is pulled, the upper edge of the baffle 2 leaves the window 1 to realize the opening of the baffle 2. To ensure that the baffle 2 will tightly cover the window 1 when there is no dragging, a return spring 5 is also installed on the baffle 2 to keep the window 1 in a normally closed state. One end of the return spring 5 is installed in the upper and middle part of the baffle 2, and the other end is installed on the window 1. In this way, when the baffle 2 is opened, the return spring 5 is stretched and deformed, and when the control motor 3 releases the baffle 2, the baffle 2 can be reset under the pull of the return spring 5 and tightly cover the window 1, thereby achieving the closing of the baffle 2.

[0027] The control of the baffle 2 by the control motor 3 is realized through the traction member. Specifically, the baffle 2 is fixedly connected with a branch traction member 6. The branch traction member 6 in this embodiment can be a relatively strong traction rope such as a thin steel wire or a glass wire. The control motor 3 is provided with a first output head 71 and a second output head 72 with synchronous output and opposite output directions. The first output head 71 is fixedly connected with a first main traction member 81, and the second output head 72 is fixedly connected with a second main traction member 82. The first main traction member 81 and the second main traction member 82 can be relatively strong traction ropes such as traction wire ropes with little elastic deformation. The branch traction member 6 is tautly fixedly connected to the first main traction member 81 or the second main traction member 82. Specifically, the branch traction member 6 connected to the baffle 2 of the first group of windows 1 is fixedly connected to the first main traction member 81, and the branch traction member 6 connected to the baffle 2 of the second group of windows 1 is fixedly connected to the second main traction member 82. In this embodiment, the branch traction members 6 of the first group of windows 1 are each passed through a branch pulley 91 for positioning and then fixedly tied to the first main traction member 81, and the branch traction members 6 of the second group of windows 1 are also each passed through a branch pulley 91 for positioning and then fixedly tied to the second main traction member 82. When the first main traction member 81 or the second main traction member 82 is pulled by the control motor 3, the branch traction members fixedly connected to the main traction members are linked together, thereby driving the baffle 2 to deviate from the window 1, so that the window 1 is opened.

[0028] Because the first output head 71 is bound to each branch traction member 6 fixed on the first group of windows 1 through the first main traction member 81, and the second output head 72 is bound to each branch traction member 6 fixed on the second group of windows 1 through the second main traction member 82, the first output head 71 controls the connection to the first group of windows 1, and the second output head 72 controls the connection to the second group of windows 1. The reason why two output heads with synchronous output and opposite directions are set is mainly based on the consideration of the stability of the control system. Different from a single window controlled by a single motor, when a single motor controls multiple windows, the system has a large reverse force on the control motor 3. The dual output head design can well balance the reverse force of the control motor 3 on the control motor 3 on both sides, thereby greatly improving the stability of the control system, and then ensuring the stable operation of the control motor 3. As for the output head type, you can choose a push rod, or you can choose a winch and other common mechanical designs for motor pulling objects, which are not listed here one by one. In this embodiment, the first output head 71 and the second output head 72 are push rod outputs. Since the structures of the first output head 71 and the second output head 72 are similar, the first output head 71 is taken as an example to illustrate its structure. A screw rod 74 is installed inside the first output head 71 through a bearing 73. One end of the screw rod 74 receives the output from the motor body 76 through a bevel gear 75, and the screw rod 74 can realize forward and reverse rotation under the control of the motor body 76. A slideway 78 parallel to the screw rod 74 is provided on the output shaft housing 77, and a slider 79 is installed on the slideway 78. The slideway 78 limits the slider 79 so that the slider 79 can only move on the slideway 78. The screw rod 74 converts the rotation from the motor body 76 into the linear motion of the slider 79. In this way, the slider 79 can slide back and forth on the slideway 78 under the joint action of the screw rod 74 and the slideway 78. A first slider is installed on the first output head 71, and a second slider is installed on the second output head 72. One end of the first main road traction member 81 is fixed on the first slider, and one end of the second main road traction member 82 is fixed on the second slider. The other ends of the first main road traction member 81 and the second main road traction member 82 are respectively passed around a positioning pulley 92 and fixedly connected to a counterweight block 93 for straightening the main road traction members 81 and 82.

[0029] Embodiment 2:

[0030] like Figure 4As shown, the embodiment discloses a control system for opening and closing small windows of a farm shed based on a winch output, which also includes ten windows 1 to be controlled to open and close and a control motor 3 for controlling the opening and closing of the windows. Each window 1 has a baffle 2 for realizing the opening and closing of the window. The ten windows 1 to be controlled to open and close are all distributed on the same wall of the farm shed and the ten windows 1 are evenly distributed horizontally. The control motor 3 is placed below the center of the ten windows 1, that is, below the center between the fifth window and the sixth window. The windows 1 are divided into two groups, the first group of windows and the second group of windows. In this embodiment, the first to fifth windows are the first group of windows, and the sixth to tenth windows are the second group of windows.

[0031] The baffles 2 of all windows 1 are usually in a normally closed state. When the control motor 3 realizes output, the baffles 2 are pulled to deviate from the original position, so that the baffles 2 are in an open state, and the opening and closing of the window 1 is realized by opening and closing the baffles 2. The baffles 2 of the window 1 can realize the opening and closing of the above-mentioned window 1 through different installation methods. In this embodiment, the baffles 2 open downward. Specifically, the baffles 2 are hinged to the inner wall of the window 1 through the top hinge 4. When the lower section of the baffle 2 is pulled, the lower edge of the baffle 2 leaves the window 1 to realize the opening of the baffle 2. When the pulling of the lower section of the baffle 2 is released, the baffle 2 is reset due to the action of gravity, and only the cover is connected to the window 1 to realize the closing of the baffle 2.

[0032] The control of the baffle 2 by the control motor 3 is realized by a traction member, and the traction member of this embodiment is the same as that of the first embodiment, except that the output head of the control motor 3 is different from that of the first embodiment. Specifically, the baffle 2 is fixedly connected with a branch traction member 6, and the branch traction member 6 in this embodiment can be a relatively strong traction rope such as a thin steel wire or a glass wire. The control motor 3 is provided with a first output head 71' and a second output head 72' with synchronous output and opposite output directions. The first output head 71' is fixedly connected to the first main road traction member 81, and the second output head 72' is fixedly connected to the second main road traction member 82. The first main road traction member 81 and the second main road traction member 82 can be traction ropes such as traction wire ropes that are relatively strong and have little elastic deformation. The branch road traction member 6 is tightly fixedly connected to the first main road traction member 81 or the second main road traction member 82. Specifically, the branch road traction member 6 connected to the baffle 2 of the first group of windows 1 is fixedly connected to the first main road traction member 81, and the branch road traction member 6 connected to the baffle 2 of the second group of windows 1 is fixedly connected to the second main road traction member 82. In this embodiment, the branch road traction members 6 of the first group of windows 1 are each fixedly tied to the first main road traction member 81 after passing through a branch pulley 91 for positioning, and the branch road traction members 6 of the second group of windows 1 are also fixedly tied to the second main road traction member 82 after passing through a branch pulley 91 for positioning. When the first main traction member 81 or the second main traction member 82 is pulled by the control motor 3 , the branch traction members fixedly connected to the main traction members are linked together, thereby driving the baffle 2 to deviate from the window 1 , thereby realizing the opening of the window 1 .

[0033] Because the first output head 71 is bound to each branch traction member 6 fixed on the first group of windows 1 through the first main traction member 81, and the second output head 72 is bound to each branch traction member 6 fixed on the second group of windows 1 through the second main traction member 82, the first output head 71 controls the connection to the first group of windows 1, and the second output head 72 controls the connection to the second group of windows 1. The dual output head design can well balance the reverse effect of the two sides of the control motor 3 on the control motor 3, thereby greatly improving the stability of the control system, and further ensuring the stable operation of the control motor 3. In this embodiment, the first output head 71' and the second output head 72' are winch outputs. Since the structures of the first output head 71' and the second output head 71' are similar, the first output head 71' is taken as an example to explain its structure. One end of the first output head 71' receives the output from the motor body 76 through the bevel gear 75, and the first output head 71' can realize forward and reverse rotation under the control of the motor body 76. One end of the first main traction member 81 is fixed and wound on the first output head 71', and one end of the second main traction member 82 is fixed and wound on the second output head 72'. The other ends of the first main traction member 81 and the second main traction member 82 are respectively passed around a positioning pulley 92 and are respectively fixedly connected to a counterweight block 93 for straightening the main traction members 81 and 82. The first output head 71' and the second output head 72' rotate to allow the first main traction member 81 and the second main traction member 82 to be wound on the output heads respectively, thereby pulling the branch traction member 6 and finally controlling the opening and closing of the window 1.

[0034] Embodiment three:

[0035] like Figure 5 As shown, in this embodiment, the first main road traction member 81' and the second main road traction member 82' are hard long strips, the first output head 71 and the second output head 72 are the same as those in the first embodiment, and are also push rod outputs. The first output head 71 is equipped with a first slider 791, and the second output head is equipped with a second slider 792. One end of the first main road traction member 81' is fixed on the first slider 791, and one end of the second main road traction member 82' is fixed on the second slider 792. The first main road traction member 81' and the second main road traction member 82' are also slidably connected to multiple positioning blocks 94 respectively.

Therefore, any changes or modifications made according to the claims and description of the utility model should fall within the scope of the utility model patent.
