Abstract
Description
Technical Field
[0001] This utility model relates to the field of ventilation equipment technology, specifically a ventilation device for dairy cow sheds. Background Technology
[0002] Dairy cows are a common type of livestock, primarily supplying milk and meat. They are ruminants with four stomachs, enabling them to effectively digest plant fiber. Dairy cows are generally large in size, with their coats mainly consisting of black and white stripes. Dairy farming typically requires the use of dairy cow sheds. During the farming process, dairy cows produce manure in the sheds, and uneaten food scraps accumulated in corners ferment, producing unpleasant odors. Therefore, proper ventilation within the dairy cow sheds is essential.
[0003] Most current ventilation equipment operates on a one-way ventilation model to exchange air inside the cattle shed. However, different ventilation methods are suitable for different periods and conditions in the cattle shed. For example, when the air pressure inside the cattle shed is low and the oxygen is insufficient, injecting air into the cattle shed can quickly increase the oxygen content. When the cattle shed is too humid and hot, the air pressure is high, and the odor from the fermentation of accumulated cow manure and hay permeates the shed during hot weather, exhausting the air can quickly remove the stale gases inside the shed. Utility Model Content
[0004] The purpose of this invention is to provide a ventilation device for dairy cow sheds to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A ventilation system for dairy cow sheds, comprising:
[0007] The mounting frame includes a frame body, and rotating seats are fixedly installed on the upper and lower sides inside the frame body.
[0008] A fan structure includes an inner frame, with rotating sleeves fixedly installed on the outer surfaces of the upper and lower sides of the inner frame. The rotating sleeves are rotatably connected to the rotating base through bearings. The bottom side of the inner frame is fixedly connected to the output end of a second motor, and the second motor is fixedly installed on the bottom side of the frame.
[0009] The air duct structure is fixedly installed on the rear edge of the upper surface of the frame.
[0010] Furthermore, the mounting frame also includes:
[0011] A fastening edge is fixedly installed at the front opening of the frame.
[0012] Furthermore, the mounting frame also includes:
[0013] The compensation groove is provided in two places, and the two compensation grooves are formed on both sides of the inner wall of the frame.
[0014] Atomizing nozzles, wherein there are several atomizing nozzles, and the several atomizing nozzles are equally spaced and embedded inside the compensation groove;
[0015] An infusion tube is connected to each atomizing nozzle.
[0016] Furthermore, the mounting frame also includes:
[0017] A swivel opening is formed on the inner wall of the rear opening of the frame;
[0018] A rotating frame, wherein the rotating frame and the rotating opening are screwed together;
[0019] The No. 1 insect-proof net is fixedly installed inside the rotating frame.
[0020] Furthermore, the fan structure also includes:
[0021] A support frame, wherein the outer side of the support frame is fixedly connected to the inner side of the inner frame;
[0022] Motor No. 1, which is fixedly sleeved to the middle of the inner frame;
[0023] The fan blades are fixedly installed at the output end of motor number one.
[0024] Furthermore, the aforementioned air duct structure also includes:
[0025] A snap-fit bracket is fixedly snapped to the rear edge of the upper surface of the frame by bolts.
[0026] A ventilation duct is provided, which is intersected in the front and back direction on the upper side of the clip frame;
[0027] Adjustable blades are rotatably installed on both the upper and lower sides inside the ventilation duct;
[0028] A synchronous gear set, wherein two meshing gears of the synchronous gear set are fixedly connected to one end of two adjusting blades respectively;
[0029] Motor No. 3 is fixedly installed on the upper edge of one side of the clip frame, and the output end of Motor No. 3 is fixedly connected to one end of an adjusting blade.
[0030] The No. 2 insect-proof net is fixedly installed at the rear opening of the ventilation duct.
[0031] Compared with the prior art, the beneficial effects of this utility model are:
[0032] 1. The frame is installed through the walls of the dairy shed. When the air pressure inside the shed is low or oxygen is insufficient, the fan structure draws fresh air from the outside and injects it into the shed, accelerating the replenishment of air pressure and oxygen content. At this time, the air pressure inside the shed increases, forcing out stale air from the duct structure, thus achieving ventilation. When the shed is too humid and hot, the air pressure is high, or the shed is filled with odors from the fermentation of accumulated cow manure and hay during hot weather, the inner frame can be rotated 180 degrees inside the frame by motor No. 2, adjusting the airflow direction of the duct structure to quickly expel air from the shed. At this time, the air pressure inside the shed decreases, and the negative pressure suction principle is used to draw outside air from the duct structure, achieving ventilation. The appropriate ventilation direction can be selected according to the actual ventilation needs, freely choosing between two ventilation methods: injecting new air and expelling old air, or expelling old air and drawing in new air, which can appropriately meet various ventilation needs.
[0033] 2. The internal passages and ventilation ducts of the frame work together to form an air exchange channel between the cowshed and the outside. The No. 1 and No. 2 insect-proof nets keep the ventilation open while blocking mosquitoes and other insects. At the same time, the No. 3 motor can be started according to the actual ventilation direction of the fan structure. The synchronous gear set drives the two adjusting blades to rotate synchronously in opposite directions, thereby adjusting the size of the air vents on both sides of the ventilation duct and limiting the air direction, thus assisting the operation of the fan structure.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0040] Please see Figure 1-4 In this embodiment of the utility model, a ventilation device for a dairy cow shed includes an installation frame 1, a fan structure 2, and an air duct structure 3. The installation frame 1 includes a frame 101, with rotating seats 106 fixedly installed on the upper and lower sides inside the frame 101. The fan structure 2 includes an inner frame 201, with rotating sleeves 205 fixedly installed on the outer surfaces of the upper and lower sides of the inner frame 201. The rotating sleeves 205 and the rotating seats 106 are rotatably connected by bearings. The bottom side of the inner frame 201 is fixedly connected to the output end of a second motor 206, which is fixedly installed on the bottom side of the frame 101. The air duct structure 3 is fixedly installed on the rear edge of the upper surface of the frame 101.
[0041] Specifically, the frame 101 is installed through the wall of the dairy shed. When the air pressure inside the shed is low or there is insufficient oxygen, the fan structure 2 draws fresh air from the outside and injects it into the shed, accelerating the replenishment of air pressure and oxygen content. At this time, the air pressure inside the shed increases, forcing out stale air from the duct structure 3, thus achieving ventilation. When the shed is too humid and hot, the air pressure is high, or the shed is filled with odors from the fermentation of accumulated cow manure and hay during hot weather, the inner frame 201 can be rotated 180 degrees inside the frame 101 by the second motor 206, adjusting the airflow direction of the duct structure 3 to quickly expel the air from the shed. At this time, the air pressure inside the shed decreases, and the outside air is drawn from the duct structure 3 using the principle of negative pressure suction, thus achieving ventilation. The appropriate ventilation direction can be selected according to the actual ventilation needs, freely choosing between two ventilation methods: injecting new air and squeezing out old air, or expelling old air and drawing in new air, which can appropriately meet various ventilation needs.
[0042] Example 1
[0043] like Figure 1-2 As shown, in this embodiment, the mounting frame 1 also includes a compensation groove 103, an atomizing nozzle 104, and an infusion tube 105. There are two compensation grooves 103, which are opened on both sides of the inner wall of the frame 101. There are several atomizing nozzles 104, which are equally spaced and embedded inside the compensation grooves 103. The infusion tube 105 is interconnected with each atomizing nozzle 104.
[0044] In this embodiment, when air is injected into the shed using the fan structure 2, a medicine supply device can be connected to the bottom side of the infusion pipe 105 to provide medicine mist to the rear side of the fan structure 2 inside the frame 101. This can effectively replenish indoor air humidity during dry periods, and insect repellents, tranquilizers, etc. can be sprayed into the room as needed, providing convenience for breeding work.
[0045] like Figure 3 As shown, in this embodiment, the fan structure 2 also includes a support frame 202, a first motor 203, and a fan blade 204. The outer side of the support frame 202 is fixedly connected to the inner side of the inner frame 201; the first motor 203 is fixedly sleeved with the middle of the inner frame 201; and the fan blade 204 is fixedly installed at the output end of the first motor 203.
[0046] In practice, the fan blades 204 are rotated by the No. 1 motor 203 to agitate the airflow. At the same time, the inner frame 201 rotates inside the frame 101, changing the orientation of the fan blades 204 inside the frame 101, thereby adjusting the direction of the airflow.
[0047] Example 2
[0048] Based on Example 1, this invention supplements the specific method of compensating for changes in the air inside the cowshed caused by the operation of the fan structure 2 through the air duct structure 3, which was not mentioned in Example 1.
[0049] like Figure 2 , 4 As shown, in this embodiment, the mounting frame 1 further includes a fastening edge 102, a swivel 107, a swivel frame 108, and a first insect-proof net 109. The fastening edge 102 is fixedly installed at the front opening of the frame 101; the swivel 107 is opened on the inner wall of the rear opening of the frame 101; the swivel frame 108 and the swivel 107 are screwed together; the first insect-proof net 109 is fixedly installed inside the swivel frame 108; the air duct structure 3 further includes a snap-fit bracket 301, a ventilation duct 302, an adjusting blade 303, a synchronous gear set 304, a third motor 305, and a second insect-proof net 306. 1. The frame 101 is fixedly fastened to the rear edge of the upper surface by bolts; the ventilation duct 302 is opened in the front and back direction on the upper side of the mounting bracket 301; the upper and lower sides of the ventilation duct 302 are rotatably installed with adjusting blades 303; the two meshing gears of the synchronous gear set 304 are fixedly connected to one end of the two adjusting blades 303 respectively; the No. 3 motor 305 is fixedly installed on the upper edge of one side of the mounting bracket 301, and the output end of the No. 3 motor 305 is fixedly connected to one end of an adjusting blade 303; the No. 2 insect net 306 is fixedly installed at the rear opening of the ventilation duct 302.
[0050] In practice, during installation, a pre-reserved installation opening is made in the wall of the dairy cow shed. The frame 101 is passed through the pre-reserved opening, and the fastening edge 102 is fixed to the inside of the cow shed wall with bolts. The clip bracket 301 is clipped onto the upper rear surface of the frame 101 that protrudes outside the cow shed and is fixed in place with bolts. The internal channel of the frame 101 and the ventilation duct 302 cooperate with each other to form an air exchange channel between the cow shed and the outside. The first insect net 109 and the second insect net 306 respectively intercept mosquitoes and insects from the outside while maintaining ventilation. At the same time, according to the actual ventilation direction of the fan structure 2, the third motor 305 is started, and the two adjusting blades 303 are controlled to rotate synchronously in opposite directions through the synchronous gear set 304, thereby adjusting the size of the air vents on the front and rear sides of the ventilation duct 302, providing a certain restriction on the wind direction, and thus providing assistance to the operation of the fan structure 2.
