Description

Technical Field

[0001] The invention relates to the technical field of pig breeding, in particular to a pig breeding pig house. Background Art

[0002] Pig farming is an agricultural production activity, mainly raising pigs for food. Pig farming is an important industry in my country's agriculture. It plays an important role in ensuring the safe supply of meat. my country's pig farming industry is transforming from traditional pig farming to modern pig farming, and significant changes are taking place in breeding mode, regional layout, production method and production capacity.

[0003] The existing Chinese patent CN109362587B discloses an energy-saving and environmentally friendly pig house, which can drive the pigs in the pig house through the reciprocating motion of the rolling mechanism in the pig house, so that the pigs can run back and forth in the pig house following the reciprocating motion of the rolling mechanism. The reciprocating running of the pigs can effectively increase the amount of exercise, which can not only effectively improve the meat quality, but also help improve the physical fitness of the pigs. However, during the use of the above device, the live pigs can cross the horizontal plate on the rotating roller, resulting in the process of the rotating roller moving back and forth in the pig house. The live pigs may directly cross the rotating roller, and will not be driven by the rotating roller to move back and forth in the pig house, resulting in a relatively small amount of exercise for the live pigs. In addition, since the live pigs can cross the rotating roller or be driven by the rotating roller during the movement of the rotating roller, it is impossible to calculate the amount of exercise of the live pigs within a specified time, and it is not easy to control the exercise duration of the live pigs.

[0021] Example 1: Please refer to Figure 1-Figure 4 , Figure 7 A pig house for raising pigs shown in the figure includes a pig house body 1, a support frame 2 is installed inside the pig house body 1, and also includes a pushing mechanism for pushing the pigs to move back and forth inside the pig house body 1, and the pushing mechanism is installed on the lower side of the support frame 2; an anti-collision component for preventing the pushing mechanism from descending and colliding with the pigs, and the anti-collision component is installed on the outer side of the pushing mechanism; a driving component for preventing the pigs from resisting the pushing mechanism and stopping moving, and the driving component is installed on the lower side of the pushing mechanism.

[0022] The pushing mechanism includes two reciprocating screws 3 rotatably installed inside the support frame 2 through bearings, and the two reciprocating screws 3 are assembled through synchronous wheels and synchronous belts. A motor 4 is fixedly installed on the upper end of the support frame 2, and one of the reciprocating screws 3 is assembled with the motor 4 through two gears. Limiting sliders 5 are installed on the outer sides of the two reciprocating screws 3, and the limiting sliders 5 are slidably connected to the support frame 2 through limiting straight grooves. An I-frame 6 is fixedly installed on the lower ends of the two limiting sliders 5. The limiting slider 5 is located inside the limiting straight groove, which can prevent the I-frame 6 from detaching from the support frame 2.

[0023] Two symmetrically distributed grille push plates 7 are installed on the lower side of the I-shaped frame 6, and two symmetrically distributed telescopic rods 8 are fixedly installed on the upper ends of the grille push plates 7, and the upper ends of the telescopic rods 8 are fixedly connected to the I-shaped frame 6.

The steel wire ropes 9 can drive the grille push plates 7 to move upward during the left and right movement of the I-shaped frame 6, and the end of the steel wire rope 9 away from the grille push plates 7 is fixedly connected to the support frame 2 through a positioning block.

[0024] A plurality of equally spaced limiting rollers 10 are fixedly mounted on the outside of the steel wire rope 9, and the limiting rollers 10 are rollingly connected to the support frame 2 through rolling grooves. Two symmetrically distributed guide wheels 11 are fixedly mounted on the left and right ends of the I-shaped frame 6, and the connection between the guide wheels 11 and the steel wire rope 9 is rolling contact. The guide wheels 11 are used to reduce the friction resistance between the steel wire rope 9 and the I-shaped frame 6. Support bars 12 are fixedly mounted on the front and rear sides of the grille push plate 7, and support bars 13 are mounted on the left and right ends of the support bars 12, and support bars 12 and 13 are fixedly connected to the support frame 2 through positioning rods.

[0025] A blocking assembly is installed between the support bar 12 and the support bar 2 13, and the blocking assembly includes a movable support bar 14 installed at the end of the support bar 12, and a bevel portion 15 is provided on the lower side of the end of the movable support bar 14 away from the support bar 12. The movable support bar 14 is rotatably connected to the support bar 12 through a positioning shaft 16, and two symmetrically distributed coil springs 17 are fixedly sleeved on the outer side of the positioning shaft 16. The coil springs 17 are used to drive the movable support bar 14 to rotate, and the outer end of the coil spring 17 is fixedly connected to the support bar 12.

[0026] The lower end of the movable support bar 14 is movably abutted against a stopper 18, and the stopper 18 and the support bar 12 are an integrally formed structure. Connecting shafts 19 are fixedly embedded at both front and rear ends of the grille push plate 7, and the two connecting shafts 19 are close to the upper end of the grille push plate 7. Two symmetrically distributed retaining rings 20 are fixedly sleeved on the outer side of the connecting shaft 19, and a roller 21 is movably sleeved between the two retaining rings 20 corresponding to the outer side of the connecting shaft 19. The retaining ring 20 is used to prevent the roller 21 from detaching from the connecting shaft 19, and the roller 21 is in rolling contact with the upper end surfaces of the support bar 12, the support bar 2 13 and the movable support bar 14.

[0027] Working principle: When the set pig movement time is reached, the motor 4 drives the reciprocating screw 3 to rotate through two gears. The two reciprocating screws 3 rotate synchronously under the action of the synchronous wheel and the synchronous belt to drive the limit slider 5 and the two grille push plates 7 to move back and forth. When the pigs are pushed from left to right, the left grille push plate 7 is located at the lower side, and when the pigs are pushed from right to left, the right grille push plate 7 is located at the lower side; When the right grille push plate 7 pushes the pigs to the left side of the pig house, after the roller 21 on the grille push plate 7 is separated from the left end of the blocking bar 1 35, the grille push plate 7 on the right side will gradually move up under the drive of the wire rope 9 during the process of moving to the left. During the process of the grille push plate 7 gradually moving up, the roller 21 on the grille push plate 7 will abut against the movable support bar 14 and drive it to rotate. When the roller 21 on the right grille push plate 7 moves to the upper side of the left support bar 2 13, the roller 21 on the left grille push plate 7 will separate from the left support bar 2 13, so that the left grille push plate 7 can move down under the action of gravity and be located on the left side of the pigs. At this time, the reciprocating screw 3 continues to rotate to drive the I-shaped frame 6 and the grille push plate 7 to move to the right, thereby pushing the pigs to the right. When the right grille push plate 7 moves to the right, the roller 21 on the right grille push plate 7 will roll on the upper end surfaces of the support bar 12, the support bar 2, and the movable support bar 14, and the movable support bar 14 cannot rotate downward under the obstruction of the stopper 18. Therefore, when the right grille push plate 7 moves to the right, the support bar 12, the support bar 2, and the movable support bar 14 can prevent the right grille push plate 7 from moving downward. Similarly, when the left grille push plate 7 moves to the left, the support bar 12, the support bar 2, and the movable support bar 14 can also support the left grille push plate 7 through the roller 21. By pushing the pigs to move left and right on both sides of the pig herd, the pigs can walk or run back and forth in the pig house body 1 during the specified exercise time period, which not only makes the pigs exercise more during the exercise time period, but also makes it easier to control the exercise duration of the pigs.

[0028] Example 2: Please refer to Figure 5 , Figure 6 The present embodiment further explains the first embodiment, the anti-collision assembly includes a friction ball 22 fixedly sleeved on the end of the connecting shaft 19 away from the grille push plate 7, four blocking columns 23 are fixedly installed on the lower end of the support frame 2, and the four blocking columns 23 are respectively close to the four corners of the support frame 2, and a plurality of tooth grooves 24 distributed at equal distances are opened on the side of the blocking column 23 close to the friction ball 22, and the friction ball 22 is in sliding contact through the plurality of tooth grooves 24, and the plurality of tooth grooves 24 are used to increase the friction resistance between the friction ball 22 and the blocking column 23.

[0029] In this embodiment: when the roller 21 on the left grille push plate 7 is detached from the left end of the left support bar 13, or the roller 21 on the right grille push plate 7 is detached from the right end of the right support bar 13, the grille push plate 7 will move downward under the action of gravity. During the downward movement, the friction ball 22 at the end of the connecting shaft 19 will resist the blocking column 23 and move downward. In the process of the friction ball 22 resisting the blocking column 23 and moving downward, the friction ball 22 will slide in contact with the blocking column 23 through multiple tooth grooves 24, which can effectively increase the friction resistance between the friction ball 22 and the blocking column 23, thereby effectively slowing down the downward movement speed of the grille push plate 7, and effectively preventing the grille push plate 7 from falling and hitting the pigs.

[0030] Example 3: Please refer to Figure 3 , Figure 8The present embodiment further explains the first embodiment, the driving component includes a rotating shaft 25 installed on the lower side of the grille push plate 7, the lower end of the rotating shaft 25 is fixedly embedded with two symmetrically distributed levers 26, and the two ends of the two levers 26 are respectively close to the two ends of the rotating shaft 25, the lever 26 is used to rotate the rotating shaft 25, the lower end of the lever 26 is provided with a hemispherical portion 27, the outer side of the rotating shaft 25 is also movably sleeved with two symmetrically distributed sockets 28, and the connection between the sockets 28 and the grille push plate 7 is a fixed connection, the lower end of the rotating shaft 25 is also fixedly installed with a plurality of equally distributed connecting rods 29, and the lower end of the connecting rod 29 is fixedly connected with a steel ball 30.

[0031] An arc spring 31 is fixedly installed on the outer side of the steel ball 30, and the end of the arc spring 31 away from the connecting rod 29 is fixedly connected to the grille push plate 7, and a baffle 32 is fixedly installed on the side where the two grille push plates 7 are close to each other, and the baffle 32 is located at the lower end of the grille push plate 7. The connection between the steel ball 30 and the baffle 32 is a movable contact, and the contact between the steel ball 30 and the baffle 32 can produce a collision sound. A fixing bar 33 is installed on the lower side of the rotating shaft 25.

[0032] A plurality of equally spaced stoppers 34 are fixedly mounted on the upper end of the fixed bar 33, and the lever 26 is connected to the plurality of stoppers 34 in sliding contact, a stopper 35 is mounted on the upper side of the stopper 34, a stopper 36 is mounted on the left and right ends of the stopper 35, and a gap is reserved between the stoppers 35 and 36, the drum 21 is in rolling contact with the lower end surfaces of the stoppers 35 and 36, and the stoppers 35 and 36 are used to prevent the grille push plate 7 from moving upward.

[0033] In this embodiment: when the left grille push plate 7 moves to the right or the right grille push plate 7 moves to the left, the lever 26 at the lower end of the rotating shaft 25 will slide in contact with multiple block 2s 34. When the lever 26 moves with the grille push plate 7, the single block 2 34 will drive the lever 26 and the steel ball 30 to rotate. When the lever 26 moves away from the single block 2 34, the multiple steel balls 30 will rotate and hit the baffle 32 driven by the compression force of the arc spring 31, thereby generating a loud impact sound. The loud impact sound can drive the pigs away from the grille push plate 7, thereby preventing the pigs from resisting the grille push plate 7 and causing excessive resistance to the movement of the grille push plate 7 during the process of the grille push plate 7 pushing the pigs to move.
