[0004] In the above-mentioned patent, through the mutual cooperation among the telescopic sleeve, the support plate, spring A, L-shaped connecting rod, piston, air valve assembly, air storage tank, pressurization assembly and the water tank, this device realizes functions such as automatic inflation, automatic gas storage, controlling air pressure and releasing the flushing water pipe through air pressure, thereby reducing the workload of manually flushing the pigsty. However, it is difficult to ensure the feeding amount of livestock during feeding, preventing the breeding personnel from forgetting to feed and causing difficulties for the livestock to eat, resulting in malnutrition of the livestock. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a multifunctional double-layer pig breeding device, which solves the problems put forward in the above background art.

[0006] To achieve the above purposes, the present invention is realized through the following technical solutions: A multifunctional double-layer pig breeding device includes a base. On the top of the base, a support frame is fixedly installed. On the top of the base, a guardrail is fixedly installed. In the front of the guardrail, a protective door is rotatably installed. On the top of the base, a feeding box is fixedly installed. On the top of the feeding box, an automatic feeding device is arranged. On the top of the automatic feeding device, a pushing device is arranged. On the right side of the guardrail, a ventilation device is arranged. Among them, the automatic feeding device includes a sliding column, a fixing plate, a push rod, a feeding box, an elastic telescopic rod, a first moving door, an inclined block, a first rack, a first gear, a second moving door and a second rack. The sliding column is slidably installed at the bottom of the feeding box. The fixing plate is fixedly installed at the top of the sliding column. The push rod is fixedly installed at the top of the fixing plate. The feeding box is fixedly installed on the left side of the support frame. The elastic telescopic rod is fixedly installed at the bottom of the feeding box. The first moving door is fixedly installed at the movable end of the elastic telescopic rod. The inclined block is fixedly installed at the bottom of the first moving door. The first rack is fixedly installed at the front of the first moving door. The first gear is rotatably installed at the front of the feeding box. The second moving door is slidably installed inside the feeding box. The second rack is fixedly installed at the front of the second moving door. Under the action of the first spring, the fixing plate and the sliding column start to move upward and reset. The upward movement of the fixing plate drives the push rod to start moving upward. The upward movement of the push rod pushes the inclined block to start moving leftward. The leftward movement of the inclined block drives the first moving door to start moving leftward. The leftward movement of the first moving door opens the channel of the feeding box. After the channel of the feeding box is opened, the feed will fall from the bottom of the feeding box into the inside of the feeding box.

[0007] According to the above technical solution, the first rack meshes with the first gear, the first gear meshes with the second rack. The surfaces of the push rod and the inclined block close to each other are both set as inclined surfaces. A first spring is arranged between the fixing plate and the bottom of the feeding box. Through meshing, it is ensured that the first rack can drive the first gear to rotate when moving. Through meshing, it is ensured that the first gear can drive the second rack to move when rotating. By setting the inclined surface, it is ensured that the push rod can smoothly push the inclined block when moving. By setting the first spring, it is ensured that the fixing plate can achieve self-resetting.

[0008] According to the above technical solution, the pushing device includes two rotating columns, a transmission belt, a connecting rod, a cylinder and a push plate. The two rotating columns are rotatably installed at the front of the feeding box. The two rotating columns are connected by the transmission belt. One end of the connecting rod is fixedly installed at the top of the second rack. The other end of the connecting rod is fixedly installed at the bottom of the transmission belt. The cylinder slidably penetrates through the feeding box. The push plate is fixedly installed at one end of the cylinder close to the inside of the feeding box. When the second moving door moves leftward, it drives the connecting rod to start moving leftward. The leftward movement of the connecting rod drives the transmission belt to start rotating around the two rotating columns. The rotation of the transmission belt drives the push plate to start moving rightward. The rightward movement of the push plate pushes the feed inside the feeding box to move.

[0009] According to the above technical solution, the pushing device further includes a third rack, a support plate, a first rotating rod, a second gear, and a rotating plate. The third rack is fixedly installed on the top of the pushing plate. The support plate is fixedly installed on the top of the feeding box. The first rotating rod rotatably penetrates through the support plate. The second gear is fixedly installed on the top of the first rotating rod. The rotating plate is fixedly installed on the circumferential surface of the first rotating rod. When the pushing plate moves to the right, it drives the third rack to start moving to the right. The third rack moving to the right drives the second gear to start rotating. The second gear rotating drives the first rotating rod to start rotating. The first rotating rod rotating drives the rotating plate to start rotating. The rotating plate rotates to push the feed to move inside the feeding box.

[0010] According to the above technical solution, the third rack meshes with the second gear. A second spring is arranged between the pushing plate and the inner wall of the feeding box. By meshing, it is ensured that the third rack can drive the second gear to rotate when moving. By arranging the second spring, it is ensured that the pushing plate can achieve self-resetting.

[0011] According to the above technical solution, the ventilation device includes a motor, a rotating shaft, fan blades, and a protective cover. The motor is fixedly installed on the left side of the guardrail. The rotating shaft is fixedly installed at the output end of the motor. The fan blades are fixedly installed on the circumferential surface of the rotating shaft. The protective cover is fixedly installed on the right side of the guardrail. After placing livestock inside the guardrail, the motor is started, so that the motor drives the rotating shaft to start rotating. The rotating shaft rotating drives the fan blades to start rotating. The fan blades rotating blow air to the outside.

[0012] According to the above technical solution, the ventilation device further includes a second rotating rod, a knocking rod, and a convex block. The second rotating rod is rotatably installed on the circumferential surface of the rotating shaft. The knocking rod is rotatably installed at the bottom of the inner wall of the protective cover. The convex block is fixedly installed on the top of the knocking rod. When the rotating shaft rotates, it drives the second rotating rod to start rotating. The second rotating rod rotating contacts and pushes the convex block to start moving downward. The convex block moving downward drives the knocking rod to start rotating. After the second rotating rod no longer contacts the convex block, the knocking rod starts to rotate and reset under the action of the third spring. The knocking rod rotating and resetting contacts and knocks the protective cover to generate vibration.

[0013] According to the above technical solution, the mutually approaching surfaces of the second rotating rod and the convex block are both set as arc surfaces. A third spring is arranged between the knocking rod and the bottom of the inner wall of the protective cover. By setting the arc surfaces, it is ensured that the second rotating rod can smoothly push the convex block when rotating. By arranging the third spring, it is ensured that the knocking rod can achieve self-resetting.

[0014] The present invention provides a multifunctional double-layer pig breeding device. It has the following beneficial effects:

[0015] (1) In this invention, the feeding passage of the feeding box is opened by moving Door 1 to the left. After the passage of the feeding box is opened, the feed will fall from the bottom of the feeding box into the inside of the feeding trough, ensuring that the feed is not scarce and can provide sufficient nutrition required by livestock, helping them obtain enough energy, protein, vitamins, and minerals, promoting healthy growth. At the same time, sufficient nutrition is crucial for the reproductive ability of livestock, especially the fertility of female livestock. Good feeding management can increase the conception rate of female livestock, the survival rate of fetuses, and ensure the health of newborn livestock. By the mutual cooperation of Door 1 and Door 2, the feeding amount for livestock each time is ensured to be consistent, enabling livestock to obtain a stable nutrient supply, thus supporting their stable growth and development. At the same time, livestock are not affected by excessive hunger or overeating, which helps livestock maintain a good weight gain curve.

[0016] (2) In this invention, the feed inside the feeding box is pushed to move by the push plate moving to the right, ensuring that the feed can be utilized in a timely manner, preventing excessive accumulation of feed from causing local moisture accumulation, making the feed prone to spoilage or mildew. At the same time, through a mechanized or automated system, the feed supply can be managed more efficiently, reducing manpower consumption and improving the overall feeding efficiency. By the rotating plate rotating to push the feed to move inside the feeding box, it is ensured that the feed can be continuously turned during feeding, maintaining its looseness, reducing the adhesion between feeds, preventing the feed from caking and causing blockages. At the same time, it can ensure that the feed reaches livestock in a timely and effective manner, reducing manual intervention and feed supply interruption, thereby improving the efficiency of the feeding system and saving time and labor costs.

[0017] (3) In this invention, the air circulation in the breeding environment is accelerated by the fan blades rotating to blow air to the outside, reducing the indoor temperature and taking away the heat from the livestock's body surface, reducing the negative impact of high temperature on livestock. At the same time, poor ventilation will exacerbate the accumulation of pathogens in the air, increasing the risk of disease transmission. By improving air circulation, it helps to reduce the pathogen concentration and reduce the occurrence of infectious diseases. By the knocking rod rotating and resetting to contact and knock the protective cover to generate vibration, the dust and dirt accumulated on the protective cover are cleaned, ensuring unobstructed air circulation. At the same time, it avoids the accumulation of dust inside the fan, which may damage the motor or other parts, extends the service life of the fan, and reduces the frequency of maintenance and replacement of components.

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-8 , an embodiment of the present invention is: a multifunctional double-layer pig breeding device, including a base 1, a support frame 2 is fixedly installed on the top of the base 1, a guardrail 3 is fixedly installed on the top of the base 1, a protection door 4 is rotatably installed in the front of the guardrail 3, a feeding box 5 is fixedly installed on the top of the base 1, and an automatic feeding device is arranged on the top of the feeding box 5; Among them, the automatic feeding device includes a sliding column 6, a fixing plate 7, a push rod 8, a feeding box 9, an elastic telescopic rod 10, a first moving door 11, an inclined block 12, a first rack 13, a first gear 14, a second moving door 15 and a second rack 16. The sliding column 6 is slidably installed at the bottom of the feeding box 5, the fixing plate 7 is fixedly installed at the top of the sliding column 6, the push rod 8 is fixedly installed at the top of the fixing plate 7, the feeding box 9 is fixedly installed on the left side of the support frame 2, the elastic telescopic rod 10 is fixedly installed at the bottom of the feeding box 9, the first moving door 11 is fixedly installed at the movable end of the elastic telescopic rod 10, the inclined block 12 is fixedly installed at the bottom of the first moving door 11, the first rack 13 is fixedly installed at the front of the first moving door 11, the first gear 14 is rotatably installed at the front of the feeding box 9, the second moving door 15 is slidably installed inside the feeding box 9, and the second rack 16 is fixedly installed at the front of the second moving door 15. The passage of the feeding box 9 is opened by the leftward movement of the first moving door 11. After the passage of the feeding box 9 is opened, the feed will fall from the bottom of the feeding box 9 into the feeding box 5, ensuring that the feed is not scarce and can provide sufficient nutrition required by livestock, helping them obtain sufficient energy, protein, vitamins and minerals, promoting healthy growth. At the same time, sufficient nutrition is crucial for the reproductive ability of livestock, especially the fertility of female livestock. Good feeding management can increase the conception rate of female livestock and the survival rate of fetuses, ensuring the health of newborn livestock.

[0022] The first rack 13 meshes with the first gear 14, the first gear 14 meshes with the second rack 16. The surfaces of the push rod 8 and the inclined block 12 that are close to each other are both set as inclined surfaces. A first spring is arranged between the fixing plate 7 and the bottom of the feeding box 5. By meshing, it is ensured that the first rack 13 can drive the first gear 14 to rotate when moving, and by meshing, it is ensured that the first gear 14 can drive the second rack 16 to move when rotating. By setting the inclined surface, it is ensured that the push rod 8 can smoothly push the inclined block 12 when moving, and by setting the first spring, it is ensured that the fixing plate 7 can achieve self-resetting.

[0023] During the operation of this embodiment: First, the breeding personnel add the feed required for the livestock into the feeding box 9, and then check whether all components of the equipment are working properly. After confirming that it is normal, open the protective door 4, place the livestock inside the guardrail 3, and then close the protective door 4. After the livestock enter, they will eat in the feeding box 5. After the livestock finish eating the feed inside the feeding box 5, the fixed plate 7 and the sliding column 6 start to move upward and reset under the action of the first spring. The upward movement of the fixed plate 7 drives the push rod 8 to start moving upward. The upward movement of the push rod 8 pushes the inclined block 12 to start moving leftward. The leftward movement of the inclined block 12 drives the first moving door 11 to start moving leftward. The leftward movement of the first moving door 11 opens the passage of the feeding box 9. After the passage of the feeding box 9 is opened, the feed will fall from the bottom of the feeding box 9 into the feeding box 5, ensuring that the feed is not scarce and can provide sufficient nutrition required by the livestock, helping them obtain sufficient energy, protein, vitamins, and minerals, promoting healthy growth. At the same time, sufficient nutrition is crucial for the reproductive ability of livestock, especially the fertility of female livestock. Good feeding management can increase the conception rate of female livestock, the survival rate of fetuses, and ensure the health of newborn livestock. After the feed enters the feeding box 5, the fixed plate 7 starts to move downward under the influence of the feed, compressing the first spring and driving the push rod 8 to start moving downward. The downward movement of the push rod 8 no longer pushes the inclined block 12. At this time, the first moving door 11 starts to move rightward and reset under the push of the movable end of the elastic telescopic rod 10. The rightward movement of the first moving door 11 drives the first rack 13 to start moving rightward. The rightward movement of the first rack 13 drives the first gear 14 to start rotating. The rotation of the first gear 14 drives the second rack 16 to start moving leftward. The leftward movement of the second rack 16 drives the second moving door 15 to start moving leftward. The leftward movement of the second moving door 15 opens the passage between it and the first moving door 11. After the passage is opened, the feed enters the passage and falls on the top of the first moving door 11. After the first moving door 11 is opened, the second moving door 15 closes. The feed falls and enters the feeding box 5. Through the mutual cooperation of the first moving door 11 and the second moving door 15, it is ensured that the feeding amount for the livestock is consistent each time, enabling the livestock to obtain a stable nutrient supply, thus supporting its stable growth and development. At the same time, the livestock are not affected by excessive hunger or overeating, which helps the livestock maintain a good weight gain curve.

[0024] Please refer to Figures 1-8, on the basis of the above embodiments, in another embodiment of the present invention, a pushing device is provided at the top of the automatic feeding device, and a ventilation device is provided on the right side of the guardrail 3. The pushing device includes two rotating columns 171, a transmission belt 172, a connecting rod 173, a cylinder 174, and a pushing plate 175. The two rotating columns 171 are rotatably installed at the front of the feeding box 9. The two rotating columns 171 are connected by the transmission belt 172. One end of the connecting rod 173 is fixedly installed at the top of the second rack 16, and the other end of the connecting rod 173 is fixedly installed at the bottom of the transmission belt 172. The cylinder 174 slides through the feeding box 9, and the pushing plate 175 is fixedly installed at one end of the cylinder 174 close to the inside of the feeding box 9. By moving the pushing plate 175 to the right, the feed inside the feeding box 9 is pushed to move, ensuring that the feed can be utilized in time, preventing excessive accumulation of feed from causing local moisture accumulation, making the feed prone to deterioration or mildew. At the same time, through a mechanized or automated system, the feed supply can be managed more efficiently, reducing the consumption of manpower and improving the overall feeding efficiency.

[0025] The pushing device further includes a third rack 176, a support plate 177, a first rotating rod 178, a second gear 179, and a rotating plate 1710. The third rack 176 is fixedly installed at the top of the pushing plate 175. The support plate 177 is fixedly installed at the top of the feeding box 9. The first rotating rod 178 rotates through the support plate 177. The second gear 179 is fixedly installed at the top of the first rotating rod 178. The rotating plate 1710 is fixedly installed on the circumferential surface of the first rotating rod 178. By rotating the rotating plate 1710, the feed inside the feeding box 9 is pushed to move, ensuring that the feed can be continuously turned during feeding, maintaining its looseness, reducing the adhesion between feeds, preventing the feed from caking and causing blockage. At the same time, it can ensure that the feed reaches the livestock in a timely and effective manner, reducing manual intervention and feed supply interruption, thereby improving the efficiency of the feeding system, saving time and labor costs.

[0026] The third rack 176 meshes with the second gear 179. A second spring is provided between the pushing plate 175 and the inner wall of the feeding box 9. By meshing, it is ensured that the third rack 176 can drive the second gear 179 to rotate when moving, and by setting the second spring, it is ensured that the pushing plate 175 can achieve self-resetting.

[0027] The ventilation device includes a motor 181, a rotating shaft 182, a fan blade 183, and a protective cover 184. The motor 181 is fixedly installed on the left side of the guardrail 3. The rotating shaft 182 is fixedly installed at the output end of the motor 181. The fan blade 183 is fixedly installed on the circumferential surface of the rotating shaft 182. The protective cover 184 is fixedly installed on the right side of the guardrail 3. By rotating the fan blade 183 to blow air to the outside, the air circulation in the feeding environment is accelerated, the indoor temperature is reduced, and the heat on the body surface of the livestock is taken away, reducing the negative impact of high temperature on the livestock. At the same time, poor ventilation will exacerbate the accumulation of pathogens in the air, increasing the risk of disease transmission. By improving air circulation, it helps to reduce the pathogen concentration and reduce the occurrence of infectious diseases.

[0028] The ventilation device further includes a second rotating rod 185, a knocking rod 186, and a bump 187. The second rotating rod 185 is rotatably installed on the circumferential surface of the rotating shaft 182. The knocking rod 186 is rotatably installed at the bottom of the inner wall of the protective cover 184. The bump 187 is fixedly installed on the top of the knocking rod 186. By the knocking rod 186 rotating and resetting to contact and knock the protective cover 184 to generate vibration, the accumulated dust and dirt on the protective cover 184 are cleaned, ensuring unobstructed air circulation. At the same time, it avoids the accumulation of dust inside the fan, which may damage the motor 181 or other parts, extends the service life of the fan, and reduces the frequency of maintenance and component replacement.

[0029] The surfaces of the second rotating rod 185 and the bump 187 that are close to each other are both set as arc surfaces. A third spring is arranged between the knocking rod 186 and the bottom of the inner wall of the protective cover 184. By setting the arc surfaces, it ensures that the second rotating rod 185 can smoothly push the bump 187 when rotating. By setting the third spring, it ensures that the knocking rod 186 can achieve self-resetting.

[0030] When this embodiment works: while the second moving door 15 moves to the left, it drives the connecting rod 173 to start moving to the left. The connecting rod 173 moving to the left drives the transmission belt 172 to start rotating around the two rotating columns 171. The transmission belt 172 rotating drives the push plate 175 to start moving to the right. The push plate 175 moving to the right pushes the feed inside the feeding box 9 to move, ensuring that the feed can be utilized in a timely manner, preventing excessive accumulation of feed, which may lead to local moisture accumulation, making the feed prone to deterioration or mildew. At the same time, through a mechanized or automated system, the feed supply can be managed more efficiently, reducing manpower consumption and improving the overall feeding efficiency. While the push plate 175 moves to the right, it drives the third rack 176 to start moving to the right. The third rack 176 moving to the right drives the second gear 179 to start rotating. The second gear 179 rotating drives the first rotating rod 178 to start rotating. The first rotating rod 178 rotating drives the rotating plate 1710 to start rotating. The rotating plate 1710 rotating pushes the feed inside the feeding box 9 to move, ensuring that the feed can be continuously turned over during feeding, maintaining its looseness, reducing the adhesion between the feeds, preventing the feed from caking and causing blockage. At the same time, it can ensure that the feed reaches the livestock in a timely and effective manner, reducing manual intervention and feed supply interruption, thereby improving the efficiency of the feeding system, saving time and labor costs.

[0031] After placing the livestock inside the guardrail 3, start the motor 181, which drives the rotating shaft 182 to start rotating. The rotation of the rotating shaft 182 drives the fan blade 183 to start rotating. The rotation of the fan blade 183 blows air outwards to accelerate the air circulation in the breeding environment, reduce the indoor temperature, and take away the heat from the livestock's body surface, reducing the negative impact of high temperature on the livestock. At the same time, poor ventilation will exacerbate the accumulation of pathogens in the air, leading to an increased risk of disease transmission. By improving the air circulation, it helps to reduce the pathogen concentration and reduce the occurrence of infectious diseases. While the rotating shaft 182 is rotating, it drives the second rotating rod 185 to start rotating. The rotation of the second rotating rod 185 contacts and pushes the convex block 187 to start moving downwards. The downward movement of the convex block 187 drives the knocking rod 186 to start rotating. After the second rotating rod 185 no longer contacts the convex block 187, the knocking rod 186 starts to rotate and reset under the action of the third spring. The rotation and reset of the knocking rod 186 contact and knock on the protective cover 184 to generate vibration, cleaning the accumulated dust and dirt on the protective cover 184, ensuring unobstructed air circulation, and at the same time preventing dust from accumulating inside the fan and causing damage to the motor 181 or other parts, extending the service life of the fan, and reducing the frequency of maintenance and replacement of parts. When the rotating shaft 182 rotates to drive the second rotating rod 185 to rotate, the speed of the rotating shaft 182 continuously increases under the drive of the motor 181, and the rotation speed of the second rotating rod 185 also continuously increases. Subsequently, the second rotating rod 185 starts to tend to be in a straight state under the action of centrifugal force. At this time, the second rotating rod 185 no longer contacts the convex block 187.
