Description

Technical Field

[0001] This invention belongs to the technical field of duck cage feeding systems, specifically an anti-arching vibration feeding device and a frequency adaptive adjustment method for duck cage feeding systems. Background Technology

[0002] With the rapid development of the poultry farming industry towards large-scale, intensive, and intelligent operations, duck cage farming has become one of the mainstream models in modern duck farming due to its ability to effectively save farming space, increase stocking density, and facilitate unified management and disease control. In duck cage farming, the feeding system is the core equipment for ensuring the healthy growth of ducks and improving farming efficiency. The smoothness and uniformity of its feeding directly affect feeding efficiency, feed utilization, and the uniformity of duck growth, thus impacting the economic benefits and production stability of the farming enterprise. Currently, most duck cage feeding systems adopt a gravity-feed structure. Feed is transported through storage bins and conveying pipes to the corresponding feeding port in the duck cage, relying on the feed's own gravity to complete the feeding operation. However, in actual aquaculture applications, because duck feed is mostly in granular or powder form, and the aquaculture environment has a certain degree of humidity, the feed is prone to forming stable arched structures at the bottom of the storage silo, inlet, or conveying pipe during storage and feeding due to its own cohesive force, inter-particle friction, and adhesion to the inner wall of the feeding device. This is known as arching (bridging). To solve this problem, vibrators are usually installed on the silo or feed box to address the issue through vibration. However, this method has the following drawbacks: As the amount of feed in the hopper decreases, the feed height decreases, and the binding force between feed particles decreases. This makes the feed more fluid as the amount of feed decreases, and the feeding speed increases. If the vibration frequency cannot be adjusted adaptively according to the changes in the amount of feed, the feeding speed will continue to increase, resulting in poor feeding uniformity. Summary of the Invention

[0003] In view of the above situation and to overcome the defects of the prior art, the present invention provides an anti-arching vibratory feeding device and a frequency adaptive adjustment method for duck cage feeding systems, which effectively solves the problems mentioned in the background art.

The ends of the two connecting rods are respectively hinged to the two internal plates. The magnetic block is located directly below the electromagnet. A guide moving part is connected to the top of the transverse cylinder.

[0005] Preferably, the inner side of the feeding rack has four layers of long duck cages arranged from top to bottom. Four limiting mechanisms are installed at equal intervals on the inner side of the feeding rack, and the long duck cages are limited and installed in the limiting mechanisms one by one. A moving drive mechanism is installed at the bottom of the inner cavity of the feeding rack. The moving drive mechanism is connected to the long duck cages and is used to drive the long duck cages to move laterally. The four feed troughs on one side correspond one-to-one with the four long duck cages. After the feed troughs are filled with feed, the ducks in the long duck cages eat from the feed troughs as the long duck cages move.

[0006] Preferably, the guide moving component includes a longitudinal rod, a guide tube is fixedly installed on the inner top wall of the material box, the longitudinal rod is movably installed inside the guide tube, guide grooves are symmetrically opened on the inner wall of the guide tube, guide blocks are symmetrically installed on both sides of the top end of the longitudinal rod, the guide blocks are slidably installed inside the guide grooves, and a direction adjustment component is provided between the longitudinal moving plate and the longitudinal rod.

[0007] Preferably, the direction adjustment component includes a bottom rotating block fixedly installed at the bottom end of the longitudinal rod, the bottom rotating block being rotatably connected to the transverse cylinder, a screw cylinder being fixedly installed at the bottom end of the bottom rotating block, a screw block being threaded on the inner side of the screw cylinder, a limiting rotating block being fixedly installed at the bottom end of the screw block, a limiting rotating groove being opened inside the longitudinal moving plate, the limiting rotating block being rotatably installed inside the limiting rotating groove, and a limiting rotating groove being fixedly installed at the top end of the longitudinal moving plate, the limiting rotating groove being sleeved on the outside of the screw cylinder.

[0008] Preferably, a ratchet and pawl mechanism is provided between the screw block and the limiting groove. The ratchet and pawl mechanism consists of pawls fixedly installed on the outer wall of the screw block and pawls set at equal angles on the inner wall of the limiting groove.

[0009] Preferably, the ratchet includes a fixed seat mounted at equal angles on the inner wall of the limiting groove, mounting plates symmetrically mounted on the fixed seat, a meshing plate between the two mounting plates, the meshing plate meshing with the ratchet, a rotating shaft mounted at the end of the meshing plate, the rotating shaft rotatably connected to the mounting plate, a torsion spring mounted between the rotating shaft and the mounting plate, and a limiting stop on one side of the meshing plate, the limiting stop being fixedly mounted on the fixed seat.

[0010] Preferably, an annular connecting frame is fixedly installed at the top of the transverse cylinder. The annular connecting frame is sleeved outside the guide tube. A connecting rod is installed at an equal angle at the top of the annular connecting frame. A top fan plate is fixedly installed at the top of the connecting rod. A material-pulling plate is installed at the bottom of the top fan plate near the inner wall edge of the material box. The top fan plate is eccentrically positioned with respect to the guide tube near the inner wall edge of the material box.

[0011] Preferably, the bottom of the material box is conical, the top of the material box is equipped with a discharge pipe with a valve, and a feed pipe is installed on one side of the material box.

[0012] Preferably, a main feed pipe is connected to the bottom end of the discharge pipe. The bottom of the main feed pipe is spherical. Branch feed pipes are evenly installed on the outside of the main feed pipe. One end of each branch feed pipe is equidistantly connected to the feed receiving trough along the length direction.

[0013] Preferably, the frequency adaptive adjustment method for the anti-arching vibration feeding device in the duck cage feeding system is as follows: S1. Vibration control: Control the electromagnet to be energized intermittently, and realize the reciprocating vibration of the vibrating block by the magnetic force generated by the electromagnet and the magnetic block. S2. Adaptive Adjustment: As the amount of feed decreases, the feed height decreases. Under the action of the top fan plate, the horizontal cylinder decreases with the feed height, which increases the distance between the electromagnet and the magnetic block, and the magnetic influence continuously decreases, thereby reducing the vibration frequency. This achieves an adaptive change in vibration frequency as the feed height decreases.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1) During operation, the electromagnet is intermittently switched on and off to generate magnetic force on the magnetic block, which drives the longitudinal plate to move longitudinally back and forth, and then drives the vibrating blocks at both ends of the transverse cylinder to move laterally back and forth to achieve vibration, so that the internal vibrating components can achieve the anti-bridging function inside the feed. 2) During operation, each time the electromagnet attracts the magnetic block and drives the longitudinal plate to move upward, the screw block moves along the screw barrel. The screw block is threadedly connected to the screw barrel and cooperates with the ratchet and pawl structure formed by the ratchet and pawl parts. This causes the transverse barrel to rotate a certain angle each time the longitudinal plate moves upward, so that the vibration direction changes continuously and the anti-arching effect is improved. 3) During operation, the top fan plate is fixedly connected to the horizontal cylinder. When the horizontal cylinder rotates, it drives the top fan plate to rotate, and then the feed near the inner wall of the feed box is moved towards the middle of the feed box by the feed-pulling plate, so as to avoid the middle of the feed box being concave due to more feed in the middle and less feed in the outside. 4) During operation, the top fan plate can be pressed against the top of the feed by the support force of the feed, and it will fall as the height of the feed decreases, so that the internal vibrating component is always inside the feed, which facilitates vibration inside the feed and improves the anti-bridging effect of the feed. 5) During operation, the horizontal cylinder descends as the feed height decreases, causing the magnetic force of the electromagnet on the magnetic block to continuously decrease. This results in the vibration frequency of the vibrating block decreasing adaptively as the amount of feed decreases. Consequently, the less feed there is, the less constraint force between feed particles, increasing fluidity and thus reducing the corresponding vibration frequency, thereby improving the uniformity of feed entering the receiving feed trough.

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] Example 1, by Figure 1-7 This invention relates to an anti-arching vibration-type feeding device for duck cage feeding systems, comprising a feeding frame 1. Four feed troughs 3 are equidistantly installed from top to bottom on both inner walls of the feeding frame 1. Feed feeding components 4 are connected to the feed troughs 3 and are used to feed the ducks into the feed troughs 3. Four layers of long duck cages are arranged from top to bottom on the inner side of the feeding frame 1. Four limiting mechanisms are equidistantly installed on the inner side of the feeding frame 1, with each long duck cage being limited within one of the limiting mechanisms. A moving drive mechanism 2 is installed at the bottom of the inner cavity of the feeding frame 1, connected to the long duck cages, and used to drive the long duck cages to move laterally. Each of the four feed troughs 3 on one side corresponds to one of the four long duck cages. After feed is filled into the feed troughs 3, the ducks inside the long duck cages eat from the feed troughs 3 as the long duck cages move.

[0020] The feed feeding assembly 4 includes a feed bin 401, an electromagnet 404 is installed on the top of the feed bin 401, and an internal vibrating element 406 is provided inside the feed bin 401. The internal vibrating element 406 includes a transverse cylinder 4061 disposed inside the material box 401. The transverse cylinder 4061 has symmetrically arranged end grooves 4062 at both ends. Two internal plates 4064 are movably installed inside the transverse cylinder 4061. A transverse rod 4063 is installed on the side of each internal plate 4064 that is far apart from each other. The outer wall of the transverse rod 4063 is in close contact with the inner wall of the end groove 4062. A vibrating block 4065 is installed at one end of the transverse rod 4063 located outside the transverse cylinder 4061. Return springs 4066 are installed at equal angles on the side of each internal plate 4064 that is far apart from each other. One end of the return spring 4066 is connected to the inner wall of the end of the transverse cylinder 4061. The two internal plates 4064... A longitudinal moving plate 4067 is provided between 064. A magnetic block 4068 is fixedly installed at the bottom of the longitudinal moving plate 4067. Connecting rods 4069 are symmetrically hinged on both sides of the longitudinal moving plate 4067. The ends of the two connecting rods 4069 are respectively hinged to the two internal plates 4064. The magnetic block 4068 is located directly below the electromagnet 404. The electromagnet 404 is intermittently energized and de-energized, generating magnetic force on the magnetic block 4068 and driving the longitudinal moving plate 4067 to move longitudinally back and forth. This, in turn, drives the vibrating blocks 4065 at both ends of the transverse cylinder 4061 to move laterally back and forth to achieve vibration, so that the internal vibrating component 406 can achieve the anti-bridging function inside the feed. A guide moving component 405 is connected to the top of the transverse cylinder 4061.

[0021] The guide moving part 405 includes a longitudinal rod 4053. A guide tube 4051 is fixedly installed on the inner top wall of the feed box 401. The longitudinal rod 4053 is movably installed inside the guide tube 4051. Guide grooves 4052 are symmetrically opened on the inner wall of the guide tube 4051. Guide blocks 4054 are symmetrically installed on both sides of the top end of the longitudinal rod 4053. The guide blocks 4054 are slidably installed inside the guide grooves 4052. A direction adjusting part 411 is provided between the longitudinal moving plate 4067 and the longitudinal rod 4053. The transverse cylinder 4061 descends as the feed height decreases, causing the magnetic force of the electromagnet 404 on the magnetic block 4068 to continuously decrease. As a result, the vibration frequency of the vibrating block 4065 decreases adaptively as the amount of feed decreases. This reduces the constraint force between feed particles and increases fluidity as the amount of feed decreases, while the corresponding vibration frequency decreases, thus improving the uniformity of feed entering the receiving feed trough 3.

[0022] The directional adjustment component 411 includes a bottom rotating block 4111 fixedly installed at the bottom end of the longitudinal rod 4053. The bottom rotating block 4111 is rotatably connected to the transverse cylinder 4061. A screw cylinder 4112 is fixedly installed at the bottom end of the bottom rotating block 4111. A screw block 4113 is threadedly installed on the inner side of the screw cylinder 4112. A limiting rotating block 4114 is fixedly installed at the bottom end of the screw block 4113. A limiting rotating groove 4115 is opened inside the longitudinal moving plate 4067. The limiting rotating block 4114 is rotatably installed inside the limiting rotating groove 4115. The limiting rotating groove 4115 is fixedly installed at the top end of the longitudinal moving plate 4067. The limiting rotating groove 4115 is sleeved on the outside of the screw cylinder 4112. The screw block 4113... A ratchet and pawl mechanism is provided between the limiting groove 4115 and the ratchet and pawl mechanism. The ratchet and pawl mechanism consists of a ratchet piece 4117 fixedly installed on the outer wall of the screw block 4113 and a ratchet piece 4117 set at equal angles on the inner wall of the limiting groove 4115. Each time the electromagnet 404 generates an attraction force on the magnetic block 4068 and drives the longitudinal plate 4067 to move upward, the screw block 4113 moves along the screw barrel 4112. The screw block 4113 is threadedly connected to the screw barrel 4112 and cooperates with the ratchet and pawl structure formed by the ratchet piece 4116 and the ratchet piece 4117. This causes the transverse cylinder 4061 to rotate a certain angle every time the longitudinal plate 4067 moves upward, so that the vibration direction changes continuously and the anti-arching effect is improved.

[0023] The ratchet pawl 4117 includes a fixed seat 41171 that is installed at equal angles on the inner wall of the limiting groove 4115. Mounting plates 41172 are symmetrically mounted on the fixed seat 41171. A meshing plate 41173 is provided between the two mounting plates 41172. The meshing plate 41173 is engaged with the ratchet 4116. A rotating shaft 41174 is installed at the end of the meshing plate 41173. The rotating shaft 41174 is rotatably connected to the mounting plate 41172. A torsion spring 41175 is installed between the rotating shaft 41174 and the mounting plate 41172. A limiting stop 41176 is provided on one side of the meshing plate 41173. The limiting stop 41176 is fixedly installed on the fixed seat 41171.

[0024] A ring-shaped connecting frame 407 is fixedly installed at the top of the transverse cylinder 4061. The ring-shaped connecting frame 407 is sleeved on the outside of the guide tube 4051. A connecting rod 408 is installed at an equal angle at the top of the ring-shaped connecting frame 407. A top fan plate 409 is fixedly installed at the top of the connecting rod 408. A material-pulling plate 410 is installed at the bottom of the top fan plate 409 near the inner edge of the material box 401. The top fan plate 409 is eccentrically positioned near the inner edge of the material box 401 and the guide tube 4051. The top fan plate 409 and the transverse cylinder 4061 are... 061 is fixedly connected. When the transverse cylinder 4061 rotates, it drives the top fan plate 409 to rotate. Then, the feed near the inner wall of the feed box 401 is moved towards the middle of the feed box 401 by the feed-pushing plate 410. This avoids the formation of a central depression due to more feed in the middle and less feed on the outside. The top fan plate 409 can be pressed against the top of the feed by the support force of the feed and descends as the feed height decreases. This keeps the internal vibrating element 406 inside the feed, which facilitates vibration inside the feed and improves the anti-bridging effect of the feed.

[0025] The bottom of the feed hopper 401 is conical, and the top of the feed hopper 401 is equipped with a discharge pipe 403. A valve is installed on the discharge pipe 403. A feed pipe 402 is installed on one side of the feed hopper 401. The bottom of the discharge pipe 403 is connected to a main feed pipe 5. The bottom of the main feed pipe 5 is spherical. Branch pipes 6 are evenly installed on the outside of the main feed pipe 5. One end of each branch pipe 6 is equidistantly connected to the feed receiving trough 3 along the length direction.

[0026] Working principle: When working, the feed bin 401 is first filled with duck feed. The valve on the discharge pipe 403 is opened to enter the feed feeding state. The feed in the feed bin 401 is evenly fed into the receiving feed trough 3 through the main feed pipe 5 and the branch feed pipe 6. When the moving drive mechanism 2 moves the long duck cage, the ducks at different positions in the long duck cage will put their heads into the receiving feed trough 3 to eat when they pass through the receiving feed trough 3. During feed feeding, the electromagnet 404 is intermittently switched on and off. When a positive current is applied to the electromagnet 404, it generates a magnetic force opposite to that of the magnetic block 4068, attracting the magnetic block 4068. When a reverse current is applied to the electromagnet 404, it generates a magnetic force equal to that of the magnetic block 4068. Thus, during the intermittent switching of the electromagnet 404, the magnetic force drives the magnetic block 4068 and the longitudinal moving plate 4067 to move longitudinally back and forth. When the longitudinal moving plate 4067 moves upward, it pushes the vibrating blocks 4065 on both sides to move outward through the connecting rod 4069. When the longitudinal moving plate 4067 moves downward, it drives the vibrating blocks 4065 to move back, causing the vibrating blocks 4065 to move laterally back and forth to vibrate and feed the external feed, thus preventing bridging. As the longitudinal plate 4067 moves upward, it drives the screw block 4113 to move upward along the screw barrel 4112. The screw block 4113 is threadedly connected to the screw barrel 4112. The ratchet 4116 on the screw block 4113 and the pawl 4117 on the limiting groove 4115 form a ratchet and pawl structure. The meshing plate 41173, which is set at equal angles, meshes with the ratchet 4116. Under the limiting action of the limiting block 41176, the meshing plate 41173 can only rotate to one side. Under the action of the torsion spring 41175, it can achieve rotation after being turned, so that when the longitudinal plate 4067 moves upward, the screw block 4113 and the limiting rotating groove 4115 rotate synchronously, driving the transverse cylinder 4061 to rotate synchronously. When the longitudinal plate 4067 moves downward, the screw block 4113 rotates itself, so that each upward movement of the longitudinal plate 4067 will drive the transverse cylinder 4061 to rotate a certain angle, so that the vibration direction of the vibrating block 4065 changes continuously, improving the vibration anti-arching effect. When the transverse cylinder 4061 rotates with the longitudinal displacement of the longitudinal plate 4067, it drives the top fan plate 409 to rotate. The edge of the top fan plate 409, namely the feeding plate 410, is eccentrically set with the guide tube 4051, so that the rotation of the transverse cylinder 4061 drives the feeding plate 410 to rotate, which causes the feed close to the inner wall of the feed box 401 to fluctuate inward, avoiding the feed being fed faster in the middle and slower at the outside, and improving the uniformity of feed feeding. Meanwhile, the top fan plate 409 has a large area, which allows the feed inside the feed box 401 to support the top fan plate 409. The top fan plate 409 presses on the top of the feed and falls with the feed height under the action of gravity. This keeps the internal vibrating element 406 inside the feed, which can prevent the feed from arching. As the height of the internal vibrating element 406 decreases, the distance between the electromagnet 404 and the magnetic block 4068 increases, which reduces the magnetic force of the electromagnet 404 on the magnetic block 4068. This causes the vibration frequency of the vibrating block 4065 to decrease adaptively as the amount of feed decreases. When the amount of feed is large, the constraint force between the feed particles is greater, and a larger vibration frequency is required to prevent arching. When the amount of feed is small, the constraint force between the particles decreases, and the feed particles are more fluid, so the vibration frequency needs to be reduced to improve the uniformity of feeding. When feeding is required into the feed bin 401, a single current is applied to the electromagnet 404, causing it to attract the magnetic block 4068, which in turn drives the horizontal cylinder 4061 to move upward. After moving to the limit position, the top fan plate 409 is positioned above the feed pipe 402, and then feed is added from the feed pipe 402 into the feed bin 401.
