Description

Technical Field

[0001] This utility model relates to the field of livestock breeding equipment technology, and in particular to an energy-saving sheepfold ventilation device. Background Technology

[0002] In livestock farming, the ventilation conditions of sheep sheds directly affect the growth and health of sheep and the efficiency of farming. Good ventilation can promptly remove stale air, ammonia, and moisture from the sheep shed, introduce fresh air, and reduce the probability of disease outbreaks. Currently, sheep shed ventilation equipment mainly consists of fixed exhaust fans combined with air intake structures, achieving air circulation through mechanical drive. Some equipment incorporates filter structures to intercept dust, down, and other debris, preventing them from entering the sheep shed or affecting the operation of ventilation components. This is an indispensable basic supporting equipment for large-scale sheep farming.

[0003] A search revealed a patent application with publication number CN215223781U, titled "An Efficient and Energy-Saving Automatic Ventilation Device for Black Goat Sheepfolds." While such existing ventilation equipment can achieve basic automatic ventilation functions, the exhaust components are mostly fixed structures, lacking targeted auxiliary cleaning and anti-clogging components. During long-term use, the filters or meshes along the exhaust path are easily clogged by shed wool from the sheep, dust, and other debris, leading to increased ventilation resistance and decreased ventilation efficiency. This not only increases energy consumption but also requires frequent manual disassembly and cleaning, resulting in high maintenance costs. Furthermore, manual cleaning can easily affect the stability of the breeding environment within the sheepfold, making it difficult to meet the high-efficiency operation and maintenance needs of large-scale farming. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an energy-saving sheepfold ventilation system.

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

[0006] An energy-saving sheepfold ventilation system includes a sheepfold with an opening and closing door on the front. The side walls of the sheepfold have air inlets with air inlets and an exhaust duct with an exhaust duct. Two rotating slots are located on the inner top of the sheepfold, each containing a reciprocating screw and a fixed sliding rod. A drive motor, fixedly connected to the reciprocating screw, is fixedly installed outside the sheepfold. Both the reciprocating screw and the sliding rod have a screw nut and a slider respectively, each with a limiting mechanism. A connecting frame is provided on both the screw nut and the slider via an engagement mechanism. Each connecting frame is equipped with... The system includes a compression groove, within which a limiting block is provided by a first compression mechanism. The inner wall of the sheepfold has a long, narrow limiting opening corresponding to the limiting block. Two connecting frames are connected to a movable mesh frame, within which an exhaust fan is installed. Movable grooves are provided on both inner walls of the movable mesh frame, and vertical rods are fixedly installed within these grooves. Sliding sleeves are provided on the vertical rods via a second compression mechanism. Two sliding sleeves are connected to an installation frame, which has an intercepting net. A drive shaft is rotatably mounted on the movable mesh frame, connected to the installation frame via a contact mechanism, and connected to the sheepfold via a transmission mechanism.

[0007] Preferably, the limiting mechanism includes limiting rods fixedly installed in the rotating groove, and the two limiting rods slide through the lead screw nut and the slider respectively.

[0008] Preferably, the insertion mechanism includes an insertion block fixedly installed on the lead screw nut and the slider, and the connecting frame is provided with a connecting groove, the inner wall of the connecting groove being provided with a slot corresponding to the insertion block.

[0009] Preferably, the first extrusion mechanism includes a first spring disposed in the extrusion groove, and the two ends of the first spring are fixedly connected to the inner wall of the extrusion groove and the outer wall of the limiting block, respectively.

[0010] Preferably, the second extrusion mechanism includes a second spring disposed in the movable groove, the second spring being sleeved on the outside of the vertical rod, and the two ends of the second spring being fixedly connected to the inner wall of the movable groove and the outer wall of the sliding sleeve, respectively.

[0011] Preferably, the contact mechanism includes a cam fixedly mounted on the drive shaft, and an arc-shaped contact block corresponding to the cam is fixedly provided at the bottom of the mounting frame.

[0012] Preferably, the transmission mechanism includes a gear fixedly mounted on a transmission shaft, and the inner wall of the sheepfold is provided with a hidden groove, the inner wall of which is fixedly provided with a rack that meshes with the gear.

[0013] Preferably, the extrusion groove, the limiting block, the first spring, and the elongated limiting opening are all inclined downwards, and a baffle is fixedly provided on the mounting frame.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model achieves automatic vibration cleaning of the interception net by cooperating with the transmission mechanism and the elastic extrusion mechanism. During the movement of the movable net frame, the cam can be driven to rotate synchronously, periodically lifting the mounting frame and generating vibration by means of the second spring to reset. This quickly shakes off the lint, dust and other debris in the interception net holes, avoiding net hole blockage without manual intervention, ensuring smooth ventilation path, maintaining stable ventilation efficiency and reducing energy loss.

[0016] 2. The equipment adopts a plug-in connection structure and an unlockable limit mechanism. By squeezing the limit block, the connecting frame can be separated from the screw nut and slider, realizing the overall disassembly of the movable mesh frame and the ventilation and cleaning components. This facilitates in-depth maintenance or replacement of core components such as exhaust fans and interception nets. The operation is simple, requires no complicated tools, and greatly reduces maintenance difficulty and labor costs.

[0017] 3. The limiting mechanism can effectively prevent the lead screw nut from rotating with the reciprocating lead screw and the slider from rotating around the slide rod, ensuring smooth reciprocating movement of the movable mesh frame; the inclined extrusion groove, limiting block and baffle blocking the movable groove can effectively prevent dust and impurities from entering the mechanism, protect the normal operation of core components such as springs and drive shafts, and extend the service life of the equipment; at the same time, the reciprocating movement of the movable mesh frame can expand the exhaust coverage area and improve the uniformity of air circulation in the sheepfold.

[0018] 4. The equipment can realize the reciprocating movement of the movable mesh frame and the self-cleaning function of the interception net simultaneously through a single drive motor, without the need for additional drive components, which simplifies the structure and reduces energy consumption; the overall structure is compact and suitable for breeding various sheep flocks such as black goats and sheep, making it highly practical.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 1 to 5 An energy-saving sheepfold ventilation system includes a sheepfold 1. The sheepfold 1 has an opening / closing door 3 on its front through an opening / closing port 2. The sheepfold 1 has an air inlet net 5 on its side wall through an air inlet 4. The sheepfold 1 has an air outlet net 6 on its top through an exhaust channel 8. The inner top of the sheepfold 1 has two rotating grooves 24, each containing a reciprocating screw 25 and a fixed sliding rod 36. A drive motor 7, fixedly connected to the reciprocating screw 25, is fixedly installed outside the sheepfold 1. Both the reciprocating screw 25 and the sliding rod 36 have screw nuts 26 and sliders 37 respectively, each with a limiting mechanism. Both screw nuts 26 and sliders 37 have connecting frames 29 via an insertion mechanism. Each connecting frame 29 has... There is an extrusion groove 32, and a limiting block 33 is provided in the extrusion groove 32 through the first extrusion mechanism. The inner wall of the sheepfold 1 is provided with a long strip limiting opening 35 corresponding to the limiting block 33. Two connecting frames 29 are connected to a movable net frame 9. An exhaust fan 11 is installed in the movable net frame 9. Movable grooves 20 are provided on both sides of the inner wall of the movable net frame 9. A vertical rod 21 is fixedly provided in the movable groove 20. A sliding sleeve 22 is provided on the vertical rod 21 through the second extrusion mechanism. The two sliding sleeves 22 are connected to an installation frame 16. An intercepting net 17 is provided on the installation frame 16. A drive shaft 10 is rotatably installed on the movable net frame 9. The drive shaft 10 is connected to the installation frame 16 through a contact mechanism. The drive shaft 10 is connected to the sheepfold 1 through a transmission mechanism.

[0027] The limiting mechanism includes limiting rods 27 fixedly installed in the rotating groove 24. The two limiting rods 27 slide through the lead screw nut 26 and the slider 37 respectively. The limiting rods 27 can prevent the lead screw nut 26 from rotating with the reciprocating lead screw 25 and can prevent the slider 37 from rotating around the sliding rod 36.

[0028] The engagement mechanism includes a plug 28 fixedly mounted on the lead screw nut 26 and the slider 37. The connecting frame 29 is provided with a connecting groove 30, and the inner wall of the connecting groove 30 is provided with a slot 31 (groove) corresponding to the plug 28 (protrusion). The lead screw nut 26 and the slider 37 are both circular, and the connecting groove 30 is U-shaped, which can realize the stable connection between the connecting frame 29 and the lead screw nut 26 and the slider 37. When the plug 28 is in the slot 31, when the lead screw nut 26 moves on the reciprocating lead screw 25, the connecting frame 29 and the movable mesh frame 9 and other components can move synchronously.

[0029] The first extrusion mechanism includes a first spring 34 disposed within the extrusion groove 32. Both ends of the first spring 34 are fixedly connected to the inner wall of the extrusion groove 32 and the outer wall of the limiting block 33, respectively. The elastic potential energy provided by the first spring 34 extrudes the limiting block 33, causing it to enter the elongated limiting opening 35. This prevents components such as the connecting frame 29 from descending vertically, thus avoiding detachment from components such as the lead screw nut 26.

[0030] The second compression mechanism includes a second spring 23 disposed within the movable groove 20. The second spring 23 is sleeved on the outside of the vertical rod 21, and its two ends are fixedly connected to the inner wall of the movable groove 20 and the outer wall of the sliding sleeve 22, respectively. When the sliding sleeve 22 rises, it can compress the second spring 23. Once the sliding sleeve 22 loses external force, the second spring 23 resets, causing the sliding sleeve 22 to descend and reset, and impacting the bottom wall of the movable groove 20 to generate vibration. This vibration can ultimately be transmitted to the intercepting net 17, shaking off debris from the net holes.

[0031] The contact mechanism includes a cam 15 fixedly mounted on the drive shaft 10, and an arc-shaped contact block 18 corresponding to the cam 15 is fixedly provided at the bottom of the mounting frame 16. The cam 15, in conjunction with the arc-shaped contact block 18, can reciprocate to lift the mounting frame 16.

[0032] The transmission mechanism includes a gear 13 fixedly mounted on a transmission shaft 10. A hidden groove 12 is provided on the inner wall of the sheepfold 1, and a rack 14 that meshes with the gear 13 is fixedly mounted on the inner wall of the hidden groove 12. The rack 14 is installed offset from the connecting frame 29, so it does not affect the descent of the connecting frame 29. The arrangement of the rack 14 and other components allows the cam 15 to rotate when the movable mesh frame 9 and other components move.

[0033] The extrusion groove 32, the limiting block 33, the first spring 34 and the long strip limiting port 35 are all inclined downwards. Their inclined downwards setting can prevent dust and impurities from entering them under the action of gravity. A baffle 19 is fixedly provided on the mounting frame 16. The baffle 19 always blocks the opening of the movable groove 20, which can prevent dust and impurities from entering the movable groove 20.

[0034] All content not described in detail in this utility model specification belongs to the prior art known to those skilled in the art. Standard parts used in this utility model can be purchased from the market, and irregularly shaped parts can be customized according to the description and drawings. The specific connection methods for each part all adopt conventional methods such as bolts, rivets, and welding, which are mature technologies in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art, and the circuit connections adopt conventional connection methods in the prior art, which will not be described in detail here.

[0035] Working principle of this utility model:

[0036] When ventilation is in operation, the exhaust fan 11 and the drive motor 7 are in the starting state. The air inlet net 5 at the air inlet 4 on the side wall of the sheepfold 1 blocks external debris from entering. Fresh air flows into the sheepfold 1 through the air inlet 4, while stale air is accelerated and guided to the exhaust channel 8 by the exhaust fan 11, and finally discharged through the air outlet net 6, forming an air circulation.

[0037] During the reciprocating movement of the movable net frame 9, the gear 13 on the drive shaft 10 meshes with the rack 14 on the inner wall of the hidden groove 12. Since the rack 14 is fixed to the inner wall of the sheepfold 1, the gear 13 rotates as the movable net frame 9 moves, thereby driving the drive shaft 10 to rotate synchronously.

[0038] When the drive shaft 10 rotates, the cam 15 fixed on it rotates synchronously. During the rotation of the cam 15, it periodically pushes up the arc-shaped contact block 18 at the bottom of the mounting frame 16, causing the mounting frame 16 to move upward. The mounting frame 16 is fitted onto the vertical rod 21 on both sides by sliding sleeves 22. As the arc-shaped contact block 18 rises, the sliding sleeves 22 slide upward along the vertical rod 21, while compressing the second spring 23 in the movable groove 20 to store elastic potential energy.

[0039] When the cam 15 rotates to the point where its non-protruding end contacts the arc-shaped contact block 18, the sliding sleeve 22 loses its pushing force. The second spring 23 releases its elastic potential energy, causing the sliding sleeve 22 to descend rapidly. The mounting frame 16 then falls and impacts the bottom wall of the movable groove 20. The resulting vibration is transmitted to the intercepting net 17 on the mounting frame 16, shaking off dust, lint, and other debris trapped in the mesh of the intercepting net 17, achieving self-cleaning and preventing mesh blockage from affecting ventilation efficiency. At the same time, the baffle 19 on the mounting frame 16 always blocks the opening of the movable groove 20, preventing the shaken-off impurities or external dust from entering the movable groove 20, protecting the normal operation of the vertical rod 21 and the second spring 23.

[0040] In this solution, a ladder or other components can be used to climb to a higher position, and then a long rod-like component can be inserted into the long strip limiting port 35 and squeeze the limiting block 33, causing it to compress the first spring 34 and retract into the squeezing groove 32. Subsequently, the connecting frame 29 and other components lose their limiting position and can descend vertically to detach from the lead screw nut 26 and the slider 37. The above components are detachable, and after disassembly, they are easy to maintain and perform other operations.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
