Description

Technical Field

[0001] This utility model relates to the field of ventilation window technology, and in particular to a ventilation window actuator. Background Technology

[0002] In modern agricultural production, the ventilation system of grain silos plays a crucial role in maintaining grain quality and preventing mold and pests. Therefore, an efficient and reliable actuator for grain silo ventilation windows is particularly important. The actuator is typically driven by electricity or pneumatics. When the temperature or humidity inside the grain silo exceeds a set value, the actuator opens the ventilation window, thereby achieving air circulation, reducing humidity, and ensuring grain quality. The actuator can be integrated with Internet of Things (IoT) technology for remote monitoring and control. Farmers can monitor the ventilation status of the grain silo in real time via mobile phone or computer, enabling more effective management of grain storage. The design of the grain silo ventilation window actuator is not only an important measure to ensure food security but also a key to improving agricultural production efficiency.

[0003] The existing ventilation window actuators have very limited opening and closing speeds, which means that in the event of an emergency, they cannot close the ventilation window in a short time, allowing rainwater to enter the grain silo through the ventilation window. Therefore, this problem needs to be solved. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a ventilation window actuator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A ventilation window actuator includes a ventilation window, a connecting plate fixedly connected to one side of the top of the ventilation window, a through groove on the top of the connecting plate, an opening mechanism for opening the ventilation window inside the through groove, four limiting plates fixedly connected to the top of the connecting plate, the four limiting plates being arranged in pairs, a rotating shaft rotatably connected to the side of each pair of limiting plates away from the through groove, a constraint plate fitted onto the surface of each of the two rotating shafts, a constraint groove on one side of each pair of limiting plates, a rotating mechanism for rotating the constraint plate inside each of the two constraint grooves, and two locking grooves on the surface of each of the two constraint plates near the limiting plates, a constraint mechanism for restraining the constraint plate inside each of the two locking grooves. The constraint plates allow the ventilation window to be closed quickly.

[0007] As a further embodiment of this utility model, the opening mechanism includes a hydraulic rod, which is rotatably connected to one side of the ventilation window. A U-shaped plate is fixedly connected to the top of the hydraulic rod, and the U-shaped plate is slidably connected inside the through groove. A support column is fixedly connected to the top of the U-shaped plate, and the support column cooperates with the constraint plate and is slidably connected inside two sets of limiting plates. Two second sliding grooves are symmetrically opened inside the U-shaped plate on the side near the hydraulic rod, and two second sliders are slidably connected inside each of the two second sliding grooves. The two second sliders are fixedly connected to one side of the rotation axis of the hydraulic rod. A first sliding groove is opened on the surface of the U-shaped plate away from the two second sliding grooves, and a first slider is slidably connected inside each of the two first sliding grooves. The two first sliders are fixedly connected to one side inside the through groove. By setting up the hydraulic rod, the ventilation window can be opened.

[0008] As a further embodiment of this utility model, the rotating mechanism includes a constraint block, which is slidably connected inside the constraint groove. A motor is fixedly connected to the top of the connecting plate near the constraint block. A third gear is fixedly connected to the output shaft of the motor. A first rack is fixedly connected to the bottom of the constraint block. The first rack and the third gear cooperate with each other. A second rack is fixedly connected to the top of the constraint block. A second gear is sleeved on the surface of the rotating shaft near the second rack. The second gear and the second rack cooperate with each other. By setting the second gear, the constraint plate can be rotated.

[0009] As a further embodiment of this utility model, the constraint mechanism includes a lead screw rotatably connected to the inside of a limiting plate. A sliding plate is fitted onto the surface of the limiting plate, and locking pins are fixedly connected to the surface of the sliding plate near the two locking grooves. The two locking pins are slidably connected to one side of the limiting plate and slidably connected to the inside of the locking grooves. A first gear is fitted onto the surface of the lead screw near the second rack, and the first gear cooperates with the second rack. An adjustment mechanism for adjusting the hydraulic rod is provided at the bottom of the connecting plate. By setting the locking pins, the constraint plate can be constrained.

[0010] As a further embodiment of this utility model, the adjustment mechanism includes two limiting rods, both of which are slidably connected to one side of the connecting plate. The ends of the two limiting rods near the hydraulic rod are fixedly connected to the same push plate. Springs are sleeved on the surfaces of the two limiting rods near the push plate. One end of each spring is fixedly connected to one side of the connecting plate, and the other end of each spring is fixedly connected to one side of the push plate. By setting the push plate, the angle of the hydraulic rod can be adjusted.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This utility model employs a technical solution where a constraint plate drives the ventilation window to open, allowing for rapid closure in case of emergencies. This effectively solves the problem of limited opening and closing speeds, which prevents rainwater from entering the grain silo in emergencies. A second gear is installed on one side of the constraint plate. When the locking pin is removed, the second rack engages with the second gear, causing the second gear to rotate the constraint plate. After rotation, the constraint plate disengages from the hydraulic rod, allowing the ventilation window to quickly descend under its own weight, thus closing the ventilation window.

[0022] Reference Figure 4 and Figure 5 In a preferred embodiment, the rotating mechanism includes a constraint block 408, which is slidably connected inside the constraint groove 307. A motor 412 is fixedly connected to the top of the connecting plate 3 near the constraint block 408. A third gear 411 is fixedly connected to the output shaft of the motor 412. A first rack 409 is fixedly connected to the bottom of the constraint block 408. The first rack 409 and the third gear 411 cooperate with each other.

[0023] Reference Figure 4 and Figure 5 In a preferred embodiment, the constraint mechanism includes a lead screw 403, which is rotatably connected to the inside of the limiting plate 306. A sliding plate 405 is sleeved on the surface of the limiting plate 306. Locking pins 406 are fixedly connected to the surface of the sliding plate 405 near the two locking grooves 402.

[0025] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: When encountering some unexpected situations, the motor 412 can be started. A third gear 411 is installed on the output shaft of the motor 412, and the third gear 411 cooperates with the first rack 409 at the bottom of the constraint block 408. Thus, after the motor 412 is started, the constraint block 408 can be moved. A second rack 410 is installed on the top of the constraint block 408. Initially, the second rack 410 is engaged with the lead screw 403. The first gear 404 on the surface engages with the constraint block 408, so that when the constraint block 408 moves, the lead screw 403 also rotates synchronously. A sliding plate 405 is fitted on the surface of the lead screw 403. Two locking pins 406 are installed on the side of the sliding plate 405 near the constraint plate 4. Initially, the two locking pins 406 are installed inside the constraint plate 4. Because the locking pins 406 are constrained, when the lead screw 403 rotates, the sliding plate 405 and the locking pins 406 can move, thereby releasing the locking pins 406 from the constraint plate 4. A second gear 407 is also installed on one side of the clamping plate 4. After the locking pin 406 is removed, the second rack 410 will engage with the second gear 407 again, so that the second gear 407 can drive the clamping plate 4 to rotate. After the clamping plate 4 rotates, it will disengage from the hydraulic rod 2, so that the ventilation window 1 will quickly move downward due to its own weight, thereby achieving the purpose of closing the ventilation window 1. A push plate 302 is installed on one side of the connecting plate 3, and the push plate 302 is connected to the connecting plate 3 by a spring 303. Therefore, when the ventilation window 1 is closed, the push plate 302 will push the hydraulic rod 2 to reset it. While pushing the hydraulic rod 2, the hydraulic rod 2 will also move down. A support column 205 is installed on the top of the hydraulic rod 2. As the hydraulic rod 2 continues to move down, the support column 205 will enter the limit plate 306. After the support column 205 moves into place, the motor 412 will start again, so that the constraint plate 4 and the locking column 406 can be reset to wait for the ventilation window 1 to open again.
