[0002] Grain is the most basic living resource for the people and an important strategic material. Usually, grain depots are built to store grain. In order to adjust the temperature and humidity in the depot, ventilation windows and vents are usually set up on the walls of the depot.

[0003] When the existing granary automatically opens and closes the windows, since the ventilation windows of the granary are set at a high position, a long rod is usually used to transmit the drive of the motor to the window opening and closing actuator above to close the window. In the event of a power outage or other faults, it is difficult to open or close the ventilation window sashes, and it is necessary to use an escalator to manually close the window, which is more laborious. In addition, the vent structure is relatively simple. When the ventilation is opened for a long time, birds or other thrown debris can easily enter the granary, which may cause pollution to the grain. At the same time, when the window sash is closed, the gap between the window sash and the window frame can easily penetrate rainwater, and the sealing is poor. Utility Model Content

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1-5 As shown, a manual-automatic window opening and closing actuator comprises a ventilation window frame 1 arranged in a wall vent, a ventilation window sash 2 is movably installed inside the ventilation window frame 1 through a rotating rod, and an electric control box 3 is installed below the ventilation window frame 1;

[0025] A transmission shaft 4 is rotatably installed at the front end of the wall through a fixed block 5, and the position of the transmission shaft 4 matches the ventilation window frame 1. The upper position of the outer ring of the transmission shaft 4 is connected to the front end side of the ventilation window sash 2 through a fixed connecting rod 6. A dual-input and output reducer 7 is installed inside the electric control box 3, and an output shaft 9 of the dual-input and output reducer 7 is connected to the bottom end of the transmission shaft 4. A motor 8 is installed inside the electric control box 3, and a controller matching the motor 8 is provided inside the electric control box 3. The driving shaft of the motor 8 is connected to one side input end 1 of the dual-input and output reducer 7, and the lower output shaft 2 of the dual-input and output reducer 7 is connected to a limiter 10.

[0026] In this embodiment, a hand crank is placed inside the electric control box 3, and the hand crank matches the input terminal 2 of the dual-input and output reducer 7, and a socket matching the hand crank is opened on the side of the electric control box 3 close to the input terminal 2. By connecting the hand crank to the input terminal 2, and then rotating the crank arm forward and reversely, the transmission shaft 4 and the fixed connecting rod 6 are driven to rotate, and the ventilation window 2 is opened or closed, which facilitates the manual opening and closing of the window and improves the flexibility of use.

[0027] In this embodiment, a protective component 11 is arranged above the ventilation window frame 1, and the protective component 11 includes a slide groove 12 and a driving gear 13. A fixing groove matching the slide groove 12 is opened at the front end of the wall and close to the top of the ventilation window frame 1, and the slide groove 12 is installed in the fixing groove by fixing bolts, and the driving gear 13 is installed at the top of the transmission shaft 4, which is convenient for fixing the slide groove 12 and facilitating the installation of other components.

[0028] In this embodiment, a slider 14 is slidably installed inside the slide groove 12, and the height of the slider 14 matches the height of the driving gear 13. A driven rack 16 is fixedly connected to the upper front end of the slider 14. The driven rack 16 is meshed and matched with the driving gear 13, and the slider 14 is meshed and connected with the driving gear 13 through the driven rack 16. When the ventilation window sash 2 is opened, the transmission shaft 4 rotates, thereby driving the driving gear 13 to rotate, and the driving gear 13 meshes and drives the slider 14 to move, which is convenient for transmission.

[0029] In this embodiment, a protective net 15 is installed at the lower front end of the slider 14 by installing bolts, and the size of the protective net 15 matches the ventilation window frame 1. Since the protective net 15 is installed on the slider 14, it can move with the slider 14. The protective net 15 serves to shield the ventilation window frame 1, preventing thrown objects or most animals such as birds and rodents from entering the grain warehouse during ventilation, thereby reducing the probability of grain contamination.

[0030] In this embodiment, the protective net 15 is slidably connected to the slide groove 12, the rear end of the protective net 15 is in contact with the wall, the protective net 15 is located on the side of the ventilation window sash 2 away from the transmission shaft 4, and the protective net 15 does not contact the ventilation window sash 2. The rear end of the protective net 15 is in contact with the wall, which facilitates the elimination of gaps and prevents animals from crawling into the ventilation window frame 1 through the gaps during ventilation.

[0031] In this embodiment, a rubber sealing strip 17 is provided inside the ventilation window frame 1, and the rear end of the ventilation window sash 2 is in contact with the rubber sealing strip 17 when the ventilation window sash 2 is closed. The rubber sealing strip 17 can shield the gap between the ventilation window frame 1 and the ventilation window sash 2, thereby effectively improving the sealing performance of the ventilation window sash 2 after closing, and preventing rainwater from seeping in through the gap.

[0032] It should be noted that the utility model is a manual-automatic switch window actuator. When in use, first, when ventilating the grain depot, because the dual-input and output reducer 7 has two input ends and two output ends, and the output shaft 1 9 is located at the upper part and connected to the transmission long shaft 4, it plays a role in driving the transmission long shaft 4 to rotate, and the lower output end 2 corresponds to the output shaft 1 9, and a limiter 10 is installed to limit the rotation angle of the transmission long shaft 4, and one input end 1 of the dual-input and output reducer 7 is connected to the shaft of the motor 8, and the other input end 2 is idle, and the motor 8 is connected to the controller in the electric control box 3;

[0033] When opening the window, the motor 8 can be powered on by control, and then the motor 8 rotates forward to drive the output shaft 9 to rotate, the output shaft 9 drives the transmission shaft 4 to rotate, and the transmission shaft 4 drives the fixed connecting rod 6 to rotate to open the ventilation window sash 2, and when the rotation angle of the transmission shaft 4 reaches the limit position of the limiter 10, a signal will be sent to cut off the power of the motor 8 and stop the action, so that the rotation of the transmission shaft 4 stops;

[0034] It is convenient to open the ventilation window sash 2 at a preset angle, and the motor 8 can be reversed as needed, and the fixed connecting rod 6 can be driven to rotate in the opposite direction through the above steps to close the ventilation window sash 2 to realize the automatic opening and closing of the window;

[0035] When the grain depot is ventilated in a power-off state, the hand crank arm can be connected to another idle input terminal 2, and then the transmission long shaft 4 and the fixed connecting rod 6 can be driven to rotate by forward and reverse rotation to open or close the ventilation window sash 2, thereby realizing the function of manually opening and closing the window. The above method can realize remote control of automatic window opening and closing, and manual window opening and closing can also be realized at the same time;

[0036] A rubber sealing strip 17 is provided inside the ventilation window frame 1, and the rubber sealing strip 17 is squeezed when the ventilation window sash 2 is closed. The rubber sealing strip 17 serves to block the gap between the ventilation window frame 1 and the ventilation window sash 2, which can effectively improve the sealing performance of the ventilation window sash 2 after closing, and prevent rainwater from penetrating through the gap.

[0037] When in use, the slide groove 12 is arranged above the ventilation window frame 1, and the slider 14 is slidably installed in the slide groove 12, and the slider 14 is meshed and connected with the driving gear 13 installed on the transmission shaft 4 through the driven rack 16, and the protective net 15 is installed on the slider 14, so that when the ventilation window 2 is opened, the transmission shaft 4 drives the driving gear 13 to rotate, and the driving gear 13 meshes and drives the protective net 15 to move toward the ventilation window frame 1, so as to shield the ventilation window frame 1, prevent throwing objects or most animals such as birds and rodents from entering the grain warehouse during ventilation, and reduce the probability of grain contamination;

[0038] When closing the window, the transmission shaft 4 rotates in the opposite direction to push the ventilation sash 2 to close, thereby driving the driving gear 13 to rotate in the opposite direction, so that the driven rack 16 drives the slider 14 to slide in the slide groove 12, and the slider 14 drives the protective net 15 to move away from the ventilation window frame 1, so as to avoid the protective net 15 interfering with the closing of the ventilation sash 2.

[0039] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
