[0031] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0032] Example 1

[0033] Please combine Figures 1 to 7The feed quantitative delivery device for fattening pigs comprises a vertical plate 1, a barrel 2 and a feed control mechanism. The vertical plate 1 is suspended above a feeding trough (not shown) and can move along the extension direction of the trough of the feeding trough. The barrel 2 is arranged on the vertical plate 1. The upper half of the barrel 2 is a cylindrical structure, and the lower half is hemispherical, so that the feed can flow to the input end of the discharge pipe 3. The top opening of the barrel 2 can be used for feed input, and the bottom has a discharge pipe 3 connected thereto. The feed control mechanism is arranged on the vertical plate 1, and is used to realize intermittent quantitative delivery of feed from the discharge pipe 3 to the feeding trough.

[0034] The material control mechanism includes a first limiting groove 5, which is arranged on one side of the discharge pipe 3, a material blocking block 4 is slidably connected in the first limiting groove 5, a socket (not shown) for inserting the material blocking block 4 is provided on the discharge pipe 3, and one side of the material blocking block 4 is elastically connected to the groove wall of the first limiting groove 5 away from the discharge pipe 3. In this embodiment, the material blocking block 4 is intermittently pulled to move in a direction away from the discharge pipe 3, so that the discharge pipe 3 is periodically opened or closed.

[0035] One side of the blocking block 4 is connected to the groove wall of the first limiting groove 5 away from the discharge pipe 3 through a first spring (not shown). When the first spring is in a non-deformed state, the blocking block 4 is inserted into the discharge pipe 3.

[0036] In this embodiment, when the stopper block 4 is pulled away from the discharge pipe 3, the first spring is compressed and deformed, so that when the stopper block 4 is pulled away, the auxiliary stopper block 4 can be reinserted into the discharge pipe 3 to close the discharge pipe 3.

[0037] A first connecting rod 7 is installed on the side of the blocking block 4 away from the discharge pipe 3. The first connecting rod 7 passes through the first limiting groove 5 and is fixed with a runway-shaped and upright second limiting groove 8. A disc 9 is installed on the vertical plate 1. A limiting column 10 is arranged at the eccentric part of the disc surface of the disc 9. The limiting column 10 is movably inserted in the second limiting groove 8. When the disc 9 rotates, the limiting column 10 and the second limiting groove 8 can cooperate with each other to realize the left and right reciprocating movement of the first connecting rod 7 in its axial direction, thereby intermittently driving the blocking block 4 to separate from the discharge pipe 3.

[0038] A worm wheel 11 is coaxially fixed on the disc 9, a worm 12 matched with the worm wheel 11 is installed on the vertical plate 1, a first bevel gear 13 is fixed on the top of the worm 12, a drive motor 14 is installed on the top of the vertical plate 1, and a second bevel gear 15 matched with the first bevel gear 13 is fixed on one of the output shafts of the drive motor 14. The drive motor 14 is a double-axis motor.

[0039] The working mode of the feed control mechanism in this embodiment is: the second bevel gear 15, the first bevel gear 13, the worm 12, the worm wheel 11, and the disc 9 are driven to rotate synchronously by the driving motor 14, and the circular rotation of the disc 9 is converted into the reciprocating movement of the first limiting block 6 in the first limiting groove 5 by the first connecting rod 7 through the second limiting groove 8 and the limiting column 10, thereby driving the blocking block 4 to intermittently disengage from the discharge pipe 3, so as to realize the intermittent quantitative delivery of feed to the feeding trough by the discharge pipe 3.

[0040] The feed quantitative delivery device for fattening pigs also includes a guide rail 16, which is installed in the pig house and located directly above the feeding trough. The vertical plate 1 is movably arranged on the guide rail 16 and can move along the guide rail 16. The extension direction of the guide rail 16 matches the extension direction of the feeding trough body, so that the feed can be intermittently and quantitatively delivered to the feeding trough at equal intervals during the movement, so as to avoid the accumulation of feed in the feeding trough.

[0041] Track grooves (not shown) corresponding to the extension direction of the guide rail 16 are provided on both sides of the vertical plate 1, and track support blocks 17 are provided on both sides of the vertical plate 1 to slide and engage with the corresponding track grooves. The vertical plate 1 can be installed on the guide rail 16 through the track grooves and the track support blocks 17. Toothless gears 19 are fixed on the two output shafts of the driving motor 14, and racks 18 that match the corresponding toothless gears 19 are provided on the top walls on both sides of the guide rail 16. The two toothless gears 19 are driven to rotate by the driving motor 14, so that the intermittent cooperation between the toothless gears 19 and the racks 18 can be achieved, thereby achieving intermittent movement of the discharge pipe 3 on the feeding trough, so as to quantitatively deliver an appropriate amount of feed to each feeding position pre-designed in the feeding trough.

[0042] The quantitative feeding device for fattening pig feed also includes a feed guide mechanism, which is arranged on the vertical plate 1. The feed guide mechanism includes a feed guide plate 20 and a transmission assembly. The feed guide plate 20 is tilted and arranged below the discharge pipe 3. One end of the feed guide plate 20 is movably arranged on the vertical plate 1, and the other end extends to the feeding trough. In this embodiment, the bottom end of the feed guide plate 20 is located behind the moving direction of the barrel 2 on the guide rail 16 through the vertical plate 1, so as to quickly guide the feed fed by the discharge pipe 3 to the corresponding feeding position in the feeding trough behind the moving direction of the discharge pipe 3. The transmission assembly is arranged on the vertical plate 1, which is driven by the blocking block 4, and can drive the feed guide plate 20 to reciprocate in an arc direction to increase the swing amplitude of the feed guide plate 20, speed up the moving speed of the feed on the feed guide plate 20, and can also avoid the adhesion of the feed on the feed guide plate 20 to a certain extent, reducing the feed loss.

[0043] A reel (not shown) is fixed through the guide plate 20, and an axial hole (not shown) is opened on the vertical plate 1. The reel is inserted into the axial hole, and the reel and the axial hole are connected by a coil spring. The coil spring and the reel can help the guide plate 20 to quickly return to its original tilt angle position after the traction of the transmission assembly ends.

[0044] The transmission assembly includes a first limit block 6, which is fixed on the side of the blocking block 4 away from the discharge pipe 3. The first limit block 6 is fixedly connected to the first connecting rod 7. The bottom of the first limit block 6 protrudes below the first limit groove 5, and the bottom of the first limit groove 5 is provided with a movable groove (not marked) for the movement of the first limit block 6, so as to avoid interference with the movement of the first limit block 6.

[0045] A fixed pulley 23 is installed on one side of the discharge pipe 3, and a first wire wheel 22 is fixed on the reel. A first pull rope (not marked) is wound around the first wire wheel 22. The free end of the first pull rope passes around the fixed pulley 23 and is bolted and fixed to the bottom of the first limit block 6. The fixed pulley 23 can change the angle of the first pull rope and keep the first pull rope in a tensioned state at all times.

[0046] The working mode of the material guiding mechanism in this embodiment is:

[0047] When the material blocking block 4 is separated from the discharge pipe 3, the first limit block 6 pulls the first wire wheel 22 to rotate and release the wire through the first pull rope, and the first wire wheel 22 will drive the reel and the guide plate 20 to rotate downward and tilt at a certain angle (spring deformation). When the material blocking block 4 is reinserted into the discharge pipe 3, the reset movement of the first limit block 6 will not generate tension on the first pull rope. At this time, the reel and the first wire wheel 22 are driven by the elastic force of the spring to resume rotation, so as to recover the first pull rope released previously, thereby rotating the guide plate 20 upward and returning to its initial tilted state.

[0048] As the blocking block 4 is intermittently separated from the discharge pipe 3, the guide plate 20 can be reciprocated and tilted to accelerate the movement speed of the feed on the guide plate 20 and improve the feeding efficiency. At the same time, it can also avoid the adhesion of the feed on the guide plate 20 to a certain extent and reduce the loss.

[0049] Example 2

[0050] Please combine Figures 1 to 8 This embodiment is an improved solution of the embodiment 1. In this embodiment, a movable plate 24 is vertically mounted on the vertical plate 1. The movable plate 24 is located at one side of the bottom end of the guide plate 20. A spreading plate 25 capable of rotating in a certain arc around the movable plate 24 is elastically mounted at the bottom of the movable plate 24. The movable plate 24 can receive the feed guided by the guide plate 20 and guide the feed to the feeding trough. The spreading plate 25 can flatten the feed put into the feeding trough under the movement of the vertical plate 1, so that the feed is evenly distributed in the feeding trough, avoiding accumulation, facilitating the pigs to eat, and reducing the waste caused by the pigs arching the feed out of the feeding trough.

[0051] Since the feed discharged through the guide plate 20 will first flow to the movable plate 24, it will cause certain impact damage to the movable plate 24. Therefore, the movable plate 24 of this embodiment is connected to the vertical plate 1 through a telescopic rod and a second spring. Under the buffering effect of the telescopic rod and the second spring, the impact damage of the movable plate 24 can be reduced.

[0052] In this embodiment, the spreading plate 25 and the movable plate 24 are also connected via a reel and a coil spring, which can buffer the contact between the spreading plate 25 and the feed during the process of flattening the feed, thereby reducing damage to the spreading plate 25 .

[0053] A plurality of combing grooves 251 are provided at the bottom of the spreading plate 25, through which the feed can be spread out in the feeding trough along the extending direction of the trough body to form a plurality of material belts, which is convenient for pigs to eat.

[0054] In order to prevent the feed from sticking to the material spreading plate 25, a rotatable transmission gear 27 is installed at one end of the bottom of the material guide plate 20 in this embodiment, and a fixed fixed gear 26 is installed at the bottom of the vertical plate 1. The number of teeth of the fixed gear 26 is much larger than the number of teeth of the transmission gear 27, and the transmission gear 27 is always meshed with the fixed gear 26. A second wire wheel 28 is coaxially fixed on the transmission gear 27, and a second pull rope is wound around the second wire wheel 28. Two fixed blocks 29 are arranged at the bottom of the material guide plate 20, and a second connecting rod 30 is slidably inserted on the two fixed blocks 29. The free end of the second pull rope is fixed to one end of the second connecting rod 30, and a knocking wheel 32 is installed at the other end of the second connecting rod 30. The knocking wheel 32 is made of soft elastic material and is aligned with the direction of the material spreading plate 25. A ring body 31 located between the two fixed blocks 29 is sleeved and fixed on the outer side of the second connecting rod 30. A third spring (not marked) is sleeved on the outer side of the second connecting rod 30 located between the ring body 31 and the fixed block. The two ends of the third spring are respectively fixed on the side wall of the fixed block and the ring wall of the ring body 31.

[0055] In the present embodiment, at the beginning, the knocking wheel 32 does not touch the material spreading plate 25, and the third spring is in a compressed state. When the guide plate 20 rotates and tilts downward, the transmission gear 27 moves around the fixed gear 26 to rotate the transmission gear 27, and the transmission gear 27 drives the second wire wheel 28 to rotate and release the rope, which reduces the tension on the third spring. The elastic force of the third spring drives the ring body 31, the second connecting rod 30, and the knocking wheel 32 to move toward the material spreading plate 25, so that the knocking wheel 32 knocks the material spreading plate 25 and shakes off the feed attached to the surface of the material spreading plate 25. When the guide plate 20 rotates upward, the transmission gear 27 moves around the fixed gear 26 to rotate in the opposite direction, and the transmission gear 27 drives the second wire wheel 28 to rotate and collect the rope, pulls the ring body 31 and squeezes the third spring to compress it, which drives the ring body 31, the second connecting rod 30, and the knocking wheel 32 to move away from the material spreading plate 25, so that the knocking wheel 32 is separated from the material spreading plate 25 after knocking.

[0056] As the guide plate 20 rotates back and forth, this process is repeated continuously, so that the knocking wheel 32 can knock the spreading plate 25 intermittently, so as to effectively shake off the feed attached to the surface of the spreading plate 25. In this process, the spreading plate 25 can buffer the rigid contact of the knocking wheel 32 to avoid damage through the reel and the coil spring.

[0057] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
