Description

Technical Field

[0001] This utility model relates to the field of livestock breeding technology, specifically to a portable ventilation device for cattle sheds. Background Technology

[0002] In the field of ventilation in cattle sheds, traditional ventilation devices have many obvious drawbacks. In terms of mobility, most traditional devices lack convenient relocation design. In terms of support stability, the support structure of previous devices is often simple and non-adjustable. Once placed on the ground, the support height cannot be adjusted according to different ground conditions and actual needs. During the operation of the fan, it is very easy to shake or shift due to uneven ground and other factors, which will interfere with the ventilation effect. Long-term unstable operation will also accelerate the wear and tear of device parts, shorten the service life of the device, and increase the cost of breeding.

[0003] Regarding wind direction adjustment, traditional ventilation devices can only make rough adjustments to the wind direction, making it difficult to achieve precise control. Moreover, due to the vibration of the fan, the adjusted wind direction angle is very easy to deviate, resulting in insufficient ventilation in some areas of the cattle shed and excessive ventilation in other areas. It is difficult to create a uniform and comfortable air circulation environment, which is not conducive to the healthy growth of cattle and the improvement of breeding efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: a movable ventilation device for cattle sheds, comprising a frame, a fan fixedly connected to the inner wall of the frame, an adjustment assembly fixedly connected to the outer wall of the frame, and a support device symmetrically fixedly connected to the bottom end of the frame; the support device includes a lever, a fixed block symmetrically slidably connected to the outer wall of the lever, a drive gear rotatably connected to the outer wall of the fixed block, a handle fixedly connected to the outer wall of the drive gear, and a guide wheel rotatably connected to the inner wall of the handle.

[0005] Preferably, the outer wall of the fixing block is fixedly connected to the outer wall of the frame, and a ratchet is rotatably connected to the outer wall of the fixing block. A turning gear is fixedly connected to the outer wall of the ratchet, and the turning gear meshes with the drive gear. Rotating the turning lever on the fixing block causes the locking block to disengage from the ratchet, allowing the ratchet to drive the turning gear to rotate. Through the meshing of the turning gear and the drive gear, the drive gear drives the handle to rotate until the guide wheel contacts the ground, thereby supporting the entire device.

[0006] Preferably, a torsion spring is fixedly connected to the outer wall of the fixing block, and the end of the torsion spring away from the fixing block is fixedly connected to the outer wall of the actuating rod.

[0007] Preferably, a locking block is fixedly connected to the outer wall of the actuating lever, and the outer wall of the locking block is slidably connected to the outer wall of the ratchet. When the actuating lever is released, the torsion spring causes the actuating lever to rotate and reset, causing the locking block to engage with the ratchet again, thus preventing the handle from rotating and locking the support device.

[0008] Preferably, the adjustment assembly includes a mounting frame, a guide plate rotatably connected to the inner wall of the mounting frame, a worm gear fixedly connected to the outer wall of the guide plate, a rotating rod rotatably connected to the inner wall of the mounting frame, and a worm fixedly connected to the outer wall of the rotating rod. Rotating the rotating rod causes the fixedly connected worm to rotate, and through meshing with the worm gear, it causes the guide plate to rotate within the mounting frame, thus changing the air outlet angle.

[0009] Preferably, the outer wall of the mounting frame is fixedly connected to the outer wall of the frame body, and the worm gear meshes with the worm wheel.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model greatly improves the mobility of the overall device by installing universal wheels at the bottom of the frame. The design of the support device ensures the stability of the induced draft device during operation. The drive gear drives the handle to rotate until the guide wheel contacts the ground, completing the adjustment of the support height. After releasing the lever, the locking block engages with the ratchet again under the action of the torsion spring, locking the handle and preventing changes in the support height. This stable support structure ensures that the induced draft device remains stable during operation, avoiding the impact of shaking or displacement on the induced draft effect, providing a reliable guarantee for the normal operation of the fan, and extending the service life of the device.

[0012] 2. This utility model, by setting an adjustment component, allows for precise changes in the air outlet direction when the air outlet angle needs to be changed. Rotating the rotating rod causes the worm gear fixedly connected to it to rotate accordingly. Through meshing with the worm wheel, the guide plate rotates within the mounting frame. Simultaneously, utilizing the self-locking characteristics of the worm wheel and worm, the guide plate remains stable after adjusting to a suitable airflow angle, preventing angle deviation due to vibrations or other factors generated by the operation of the fan.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0019] Example:

[0020] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a movable ventilation device for cattle sheds, comprising a frame 1, a fan 4 fixedly connected to the inner wall of the frame 1, an adjustment component 2 fixedly connected to the outer wall of the frame 1, and a support device 3 symmetrically fixedly connected to the bottom end of the frame 1; the support device 3 includes a lever 31, a fixing block 32 symmetrically slidably connected to the outer wall of the lever 31, a drive gear 37 rotatably connected to the outer wall of the fixing block 32, a handle 38 fixedly connected to the outer wall of the drive gear 37, and a guide wheel 39 rotatably connected to the inner wall of the handle 38.

[0021] The outer wall of the fixing block 32 is fixedly connected to the outer wall of the frame 1. A ratchet 35 is rotatably connected to the outer wall of the fixing block 32, and a turning gear 36 is fixedly connected to the outer wall of the ratchet 35. The turning gear 36 meshes with the drive gear 37. Rotating the turning lever 31 on the fixing block 32 causes the locking block 34 to disengage from the ratchet 35, allowing the ratchet 35 to drive the turning gear 36 to rotate. Through the meshing of the turning gear 36 with the drive gear 37, the drive gear 37 drives the handle 38 to rotate until the guide wheel 39 contacts the ground, thereby supporting the entire device.

[0022] A torsion spring 33 is fixedly connected to the outer wall of the fixed block 32. The end of the torsion spring 33 away from the fixed block 32 is fixedly connected to the outer wall of the actuating rod 31. When the actuating rod 31 is released, under the action of the torsion spring 33, the actuating rod 31 is driven to rotate and reset, so that the locking block 34 is locked into the ratchet 35 again, thereby preventing the rotating handle 38 from rotating and completing the locking of the support device 3.

[0023] A locking block 34 is fixedly connected to the outer wall of the lever 31, and the outer wall of the locking block 34 is slidably connected to the outer wall of the ratchet 35.

[0024] The adjusting assembly 2 includes a mounting frame 21. A guide plate 22 is rotatably connected to the inner wall of the mounting frame 21, and a worm gear 23 is fixedly connected to the outer wall of the guide plate 22. A rotating rod 24 is rotatably connected to the inner wall of the mounting frame 21, and a worm gear 25 is fixedly connected to the outer wall of the rotating rod 24. Rotating the rotating rod 24 causes the fixedly connected worm gear 25 to rotate, which, through meshing with the worm gear 23, causes the guide plate 22 to rotate within the mounting frame 21, thus changing the air outlet angle.

[0025] The outer wall of the mounting frame 21 is fixedly connected to the outer wall of the frame 1, and the worm 25 meshes with the worm wheel 23.

[0026] Working principle:

[0027] In use, the entire device is moved by the casters at the bottom of the frame 1. When it is moved to the cattle shed, the lever 31 on the fixed block 32 is rotated through the support device 3, causing the locking block 34 to disengage from the ratchet 35. This allows the ratchet 35 to drive the actuating gear 36 to rotate. The actuating gear 36 meshes with the driving gear 37, which in turn drives the handle 38 to rotate until the guide wheel 39 contacts the ground, thus supporting the entire device. Then, the lever 31 is released, and under the action of the torsion spring 33, the lever 31 rotates back to its original position, causing the locking block 34 to engage with the ratchet 35 again, preventing the handle 38 from rotating and locking the support device 3.

[0028] At this point, the fan 4 inside the frame 1 can be turned on to start induced airflow. When the airflow direction needs to be adjusted by adjusting the component 2, the rotating rod 24 is rotated to drive the fixedly connected worm gear 25 to rotate. Through the meshing with the worm wheel 23, the guide plate 22 is driven to rotate within the mounting frame 21, changing the airflow angle. And through the self-locking property of the worm wheel 21 and the worm gear 25, precise adjustment is achieved.

[0029] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
