Description

Technical Field

[0001] The invention relates to the technical field of native pig breeding, and in particular to a feeding device for free-range native pig breeding. Background Art

[0002] Existing pig farms generally raise fat pigs collectively. Most of the food they feed is feed, and the pigs' range of activities is restricted so that they exercise less to increase their fat content and sell them at a high price. However, the fat pigs obtained by this breeding method are of poor physical health and the pork tastes bad. For this reason, free-range native pig farming was born. The biggest difference between free-range native pig farming is that the range of activities of native pigs is no longer restricted, but the free-range mode is turned on. Native pigs can run and jump in the free-range mode, and the items they eat are not only feed, but also plants in the free-range site. This free-range mode has greatly improved the health of native pigs, and they have good physical fitness and strong resistance to diseases. Free-range native pigs have strong meat and rich taste.

[0003] In a free-range environment, feed is easily contaminated by dust, rain, insects, etc. in the natural environment. For example, feed placed in the open air may be wetted by rain, causing mold and deterioration. Feed that has been crawled or bitten by insects may spread pathogens. These pollutions will not only reduce the nutritional value of the feed, but may also cause native pigs to become sick. Summary of the invention

[0037] Reference Figure 1-Figure 10Based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a first gear 211 is rotatably installed at the bottom of the inner cavity of the feed trough 201, and the first gear 211 is threadedly connected to the first threaded rod 205. When the first threaded rod 205 moves up and down, the first gear 211 can be reciprocated. A first sector gear 212 is fixedly installed on the top of the first gear 211, and the first sector gear 212 is rotatably connected to the first threaded rod 205.

The second gear 213 is fixedly installed with a second sector gear 214 on the top, and the rotation of the second gear 213 can drive the second sector gear 214 to rotate. The bottom of the inner cavity of the feed trough 201 is slidably installed with a first tooth plate 215, and the first tooth plate 215 is meshed with the first sector gear 212 and the second sector gear 214 respectively. When the first sector gear 212 rotates to contact with the first tooth plate 215, the first tooth plate 215 can slide at the bottom of the feed trough 201, and when the second sector gear 214 rotates to contact with the first tooth plate 215, the first tooth plate 215 can slide at the bottom of the feed trough 201. When the first tooth plates 215 are in contact, the sliding direction of the first tooth plates 215 can be opposite. By setting the first threaded rod 205, no matter what the movement direction of the first threaded rod 205 is, the first tooth plates 215 can slide back and forth at the bottom of the feed trough 201. Slide rods 216 are fixedly installed on both sides of the first tooth plates 215. The slide rods 216 penetrate the two sides of the partition plate 203 and are slidably connected to the partition plate 203.

The rotation of the stirring rod 220 can stir the feed to avoid the feed being placed in the feed trough 201 for too long, resulting in the phenomenon of feed segregation, resulting in unsmooth feed discharge.

[0038] Reference Figure 1-Figure 10Based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a discharging mechanism 3 is installed at the front of the fixed plate 1, and the discharging mechanism 3 includes a feeding trough 301, and the feeding trough 301 is fixedly installed at the front of the fixed plate 1, and a support plate 302 is fixedly installed at the front of the feeding trough 301, and a pedal 303 is slidably installed at the front of the feeding trough 301, and a second spring 304 is installed between the pedal 303 and the support plate 302, and a plurality of second springs 304 are provided.

The third pulley 312 is rotatably installed on both sides of the fixed plate 1. The third pulley 312 is connected to the first double-groove pulley 308 through a belt. The third pulley 312 is threadedly connected to the second threaded rod 311. When the first double-groove pulley 308 rotates, the third pulley 312 can be driven to rotate, and the rotation of the third pulley 312 can make the second threaded rod 311 move, and then can drive the baffle 310 to move, so that the baffle 310 can be moved to the side of the feeding trough 202, so that the feed can fall smoothly from the feeding trough 202. To the inside of the feeding trough 301, through the setting of the discharge mechanism 3, when the native pig needs to eat, the native pig moves to the top of the pedal 303 and presses the pedal 303 downward, thereby driving the movement of the third gear plate 305, and then the fourth gear 306 rotates, and then the feed can be discharged from the inside of the feeding trough 201. When the native pig finishes eating, it moves out of the pedal 303, and the pedal 303 returns to its original state under the action of the second spring 304, so that the baffle 310 can be moved to the inside of the lower trough 202, and the connection between the feeding trough 201 and the lower trough 202 is isolated to prevent external pollutants from entering the inside of the feeding trough 201 from the lower trough 202, thereby contaminating the feed and causing the feed to deteriorate.The first spring 221 and the second spring 304 are all sleeved with dampers.

[0039] Reference Figure 1-Figure 10Based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a limiting mechanism 4 is installed at the bottom of the feeding trough 301, and the limiting mechanism 4 includes a fourth pulley 401, which is rotatably installed at the bottom of the feeding trough 301, and the fourth pulley 401 is connected to the first pulley 210 through a belt. When the first threaded rod 205 moves downward, the first pulley 210 rotates, and the rotating first pulley 210 can drive the fourth pulley 401 to rotate. A fifth gear 402 is fixedly installed at the bottom of the fourth pulley 401, and the rotation of the fourth pulley 401 can drive the fifth gear 402 to rotate. A sixth gear 403 is rotatably installed at the bottom of the feeding trough 301, and the sixth gear 403 is provided with Two, the two sixth gears 403 are meshed with the fifth gear 402.

When the two sixth gears 403 rotate, the two third sector gears 407 can be driven to rotate, thereby making the double-toothed plate 404 reciprocate. The reciprocating motion can drive the hammer head 405 to move, so that the hammer head 405 can hit the vibrating metal sheet 406, making the vibrating metal sheet 406 make a sound. The sound of the vibrating metal sheet 406 can be used for stress training for the native pigs, so that the native pigs will spontaneously come to the feeding trough 301 to eat after hearing the sound of the vibrating metal sheet 406. A sliding plate 408 is slidably installed at the rear of the feeding trough 301. The surface of the sliding plate 408 is provided with a first tooth groove 409, and the first tooth groove 409 is meshed with the third sector gear 407 at the front.

When the limit block 414 slides to the edge of the support plate 302,The limit block 414 removes the restriction on the pedal 303, so that the pedal 303 can slide smoothly in front of the feeding trough 301. When the native pigs finish eating, the pedal 303 returns to its original state under the action of the second spring 304, and the material receiving plate 206 returns to its original state under the action of the first spring 221, so that the limit block 414 can be restored to its original position, thereby restricting the pedal 303 and preventing the native pigs from accidentally touching the pedal 303, causing the outside air to pollute the feeding trough 201.

[0040] Specifically, the working process or working principle of the feeding device for free-range native pigs is as follows: first, the feeding personnel puts the feed into the inside of the feed trough 201, and under the action of the gravity of the feed, the receiving plate 206 can be pressed downward to make the receiving plate 206 move downward, and the downward movement of the receiving plate 206 can drive the first threaded rod 205 to move downward, and the first spring 221 is compressed under the action of gravity.

[0041] At the same time, the rotating first pulley 210 can drive the fourth pulley 401 to rotate, and the rotation of the fourth pulley 401 can drive the fifth gear 402 to rotate. When the fifth gear 402 rotates, it can drive the two sixth gears 403 to rotate. When the two sixth gears 403 rotate, they can drive the two third sector gears 407 to rotate, so that the double-toothed plate 404 can make reciprocating motion, and the reciprocating motion of the double-toothed plate 404 can drive the hammer head 405 to move, so that the hammer head 405 can hit the vibrating metal sheet 406, making the vibrating metal sheet 406 make a sound, and the sound of the vibrating metal sheet 406 can perform stress training for the native pigs, so that the native pigs will spontaneously come to the feeding trough 301 to eat after hearing the sound of the vibrating metal sheet 406.

[0042] When the third sector gear 407 at the front rotates, it can drive the sliding plate 408 to slide at the rear of the feeding trough 301, and the sliding of the sliding plate 408 can drive the second tooth groove 410 at the bottom to move, and then drive the seventh gear 411 to rotate, and the rotating seventh gear 411 can drive the third threaded rod 413 to rotate, so that the limit block 414 can slide on the surface of the support plate 302, and when the limit block 414 slides to the edge of the support plate 302, the limit block 414 removes the restriction on the pedal 303, so that the pedal 303 can slide smoothly in front of the feeding trough 301.

[0043] When the pedal 303 is pressed downward, the third tooth plate 305 can be driven to move downward, and then the fourth gear 306 can be driven to rotate. The rotation of the fourth gear 306 can drive the second pulley 307 to rotate. The rotation of the second pulley 307 can drive the first double-groove pulley 308 to rotate.
