Description

Technical Field

[0001] The present invention relates to an annular feeding device, and particularly to an annular plate chain feeding device. Background Art

[0002] At present, the feeding methods for caged poultry at home and abroad are generally divided into two types: manual feeding and mechanical feeding. The disadvantages of the manual feeding method are obvious: high labor intensity of workers, high labor costs, low efficiency, feed waste, uneven feed distribution, etc., so it has been eliminated by most breeding enterprises. For the mechanical feeding method, most trough feeding machines are used in the market.

[0003] When the existing feeding device is in use, it is necessary for the operator to drive the feeding vehicle at a constant speed to keep the feeding of the feeding pipe uniform. However, the chicken farm has a large area, and the operator cannot always push the feeding vehicle at a constant speed, which will lead to uneven feeding. And after feeding, it is necessary to clean the remaining materials manually. Summary of the Invention

[0004] In order to solve the problems existing in the prior art, the present invention provides an annular plate chain feeding device.

[0005] The feeding device includes: a feeding trough arranged in a ring around the chicken coop, a feeding plate chain arranged in the feeding trough with a U-shaped cross-section, and a plate chain driving device installed above the feeding trough to drive the movement of the feeding plate chain;

[0006] Among them, the feeding plate chain is formed by connecting a number of groups of chain plates and chain rings end to end. Trapezoidal connecting holes are opened on the chain plates, and the chain plates have Z-shaped bends; adjacent two chain plates overlap at the Z-shaped bends, and are buckled together by passing the chain rings through their respective trapezoidal connecting holes; after the Z-shaped bends make the chain plates overlap each other, each chain plate still remains at the same height.

[0007] The front end width of the chain plate is smaller than its rear end to prevent the front and rear chain plates from interfering with each other when the feeding plate chain turns. The width of the rear end of the chain plate is slightly smaller than the width of the feeding trough. The width and height of the chain plate enable it to push the feed along the feeding trough when moving in the common chain trough. The front end of the chain plate has an outer arc, and the trapezoidal connecting hole of the chain plate has an inner arc notch concentric with the outer arc near the front end side. Ensure that each chain ring at the corner can rotate more flexibly when the included angle between the front and rear chain plates changes.

[0008] Further, the feeding trough is a rectangular trough surrounding the chicken coop, and four transition angle wheels are arranged on the inner sides of the four corners of the rectangular trough. The transition angle wheels are provided with teeth that are stuck between the chain plates in the turning section to prevent slipping in the corner area.

[0009] Further, tooth retaining edges are arranged on both sides of the teeth of the transition angle wheels to limit the inner edge of the chain plate.

[0010] Furthermore, in order to prevent the outer edge of the feeding plate chain from warping up in the corner area, an outer corner pressing plate is provided above the outer edge of the chain plate meshing with the teeth of the upper transition corner wheel. The outer corner pressing plate is at least in a quarter-circular arc shape, and the outer edge part of the chain plate passes through the corner area from the space between the feeding trough and the outer corner pressing plate.

[0011] Furthermore, a feeder is provided on the feeding section on the side of the chicken coop where the feeding trough is located, and a feeding limit plate is provided at the connection of the lower part of the feeder to the feeding trough.

[0012] Furthermore, the feeding limit plate is installed in a guide groove that only allows the feeding limit plate to move up and down. A locking knob for locking its own position by means of a thread is provided on the feeding limit plate. The height of the feeding limit plate is used to control the feeding amount and can be adjusted according to the chicken's demand for the amount of feed.

[0013] Furthermore, the plate chain driving device includes: a driving gear perpendicular to the bottom surface of the feeding trough and parallel to the moving direction of the feeding plate chain; a reduction motor with an output shaft connected to the driving gear.

[0014] Furthermore, in order to timely discharge the residual chicken feed in the trough and avoid the residual feed from spoiling and deteriorating in the trough, a residual material discharge hole is provided at the bottom of the feeding trough. The position of the residual material discharge hole is on the other side of the chicken coop. The U-shaped cross-section of the trough at the residual material discharge hole is wrapped with a sliding door. The two inwardly bent edges at the top of the sliding door are stuck on the top of the U-shaped trough, and the sliding door slides along the feeding trough to control the opening or closing of the residual material discharge hole.

[0015] The technical effect of the present invention is as follows: By using the plate chain laid in the feeding trough, since the width of the chain plate is slightly smaller than the width of the feeding trough and the chain plate has a Z-shaped bend, when the chain plate moves, it acts on the chicken feed similar to the bucket of a bulldozer, pushing the feed in the feeder fixed at any position in the feeding trough onto the feeding trough. When the current feeding is completed, the sliding door is pushed to expose the residual material discharge hole, and the pushing function of the chain plate is continuously used to push the residual feed in the feeding trough along with the movement of the chain plate to the residual material discharge hole. The feeding plate chain simultaneously has the functions of feeding and cleaning the residual material.

[0016] A transition caster is provided at the corner of the feeding trough to realize a 90° turn of the feeding plate chain, enabling a single feeding plate chain to move around the four sides of the chicken coop. The front and rear chain plates overlap at the Z-shaped bend. When turning, the front and rear chain plates rotate at different angles but do not interfere with each other, and the trapezoidal connection hole has an inner circular arc notch concentric with the outer circular arc on the side closer to the front end, so that when the chain link turns, it adjusts the position of its own connection according to the relative angle between the front and rear chain plates.

[0017] The total amount of feed required for single feeding has been distributed in the feeder. The feeding plate chain can evenly supply the feed to any point on the feeding trough, ensuring that the feed obtained in each area of the chicken house is equal. It is necessary to adjust the gap between the discharge port of the feeder and the bottom of the feeding trough by adjusting the height of the limit plate to achieve the adjustment of the feeding amount per unit length of the feeding trough. For traditional mobile spreaders, it is necessary to change the discharge flow rate of the spreader or the moving speed of the spreader to achieve the purpose of adjusting the feeding amount per unit length of the feeding trough.

[0029] Figures 2 to 4 Schematically shows the specific structure and connection characteristics of the chain plate 31 and the chain link 32. The feeding plate chain 3 is formed by connecting a number of groups of chain plates 31 and chain links 32 end to end. Trapezoidal connection holes 313 are opened on the chain plate 31, and the chain plate 31 has a Z-shaped bend 311; two adjacent chain plates 31 overlap at the Z-shaped bend 311 and are buckled together by passing the chain link 32 through their respective trapezoidal connection holes 313. The width of the front end of the chain plate 31 is smaller than that of its rear end, and the width of the rear end of the chain plate 31 is slightly smaller than the width of the feeding trough 1. The front end of the chain plate 31 has an outer arc 314, and the trapezoidal connection hole 313 of the chain plate 31 has an inner arc notch 312 concentric with the outer arc 314 on the side close to the front end.

[0030] Figure 5 Schematically shows the installation position of the feeder. A feeder 2 is arranged on the feeding section on the side of the chicken coop 10. A limiting plate 22 is arranged at the connection of the lower part of the feeder 2 to the feeding trough 1. Tooth guards 15 are arranged on both sides of the teeth 14 of the transition angle wheel 11.

[0031] Figure 6 Schematically shows the limiting structure of the feeder. The limiting plate 22 is installed in a guide groove 23 that only allows the limiting plate 22 to move up and down, and a lock knob 21 for locking its own position by threading is arranged on the limiting plate 22.

[0032] Figure 7 Schematically shows the turning mode of the feeding plate chain. The feeding trough 1 is a rectangular trough surrounding the chicken coop 10. Four transition angle wheels 11 are arranged on the inner sides of the four corners of the rectangular trough. The transition angle wheels 11 are provided with teeth 14 that are stuck between the chain plates 31 in the turning section; above the outer edge of the chain plate 31 meshing with the teeth 14 on the transition angle wheel 11, a turning outer pressure plate 16 is arranged. The turning outer pressure plate 16 is at least a quarter-circular arc shape, and the outer edge part of the chain plate 31 passes through the turning area from the space between the feeding trough 1 and the turning outer pressure plate 16.

[0033] Figure 8 Schematically shows the surplus material discharge hole of the feeding trough. The bottom of the feeding trough 1 is provided with a surplus material discharge hole 18. The position of the surplus material discharge hole 18 is on the other side of the chicken coop 10. The U-shaped cross-section trough outside the surplus material discharge hole 18 is wrapped with a sliding door 17, and the two inwardly bent edges at the top of the sliding door 17 are stuck at the top of the U-shaped trough.

[0034] Working principle: Adjust the height of the limiting plates 22 on both sides of the feeder 2 in the guide grooves 23 through the locking knob 21, lock the limiting plates 22, start the reduction motor 42, drive the driving gear 41 to rotate, and under the action of the driving gear 41, the feeding plate chain 3 starts to move in the feeding trough 1. As the feeding plate chain 3 moves, the feed in the feeder 2 is gradually pushed into the feeding trough 1. After the feed is evenly spread, turn off the reduction motor 42 and wait for the chickens to peck at the feed in the feeding trough 1.

[0035] After pecking, pull open the sliding door 17 to expose the residual material discharge hole 18, and start the reduction motor 42 again to make the feeding plate chain 3 gradually push the residual material in the trough through the residual material discharge hole 18, so that the residual feed leaks out from the residual material discharge hole 18, avoiding mildew and deterioration in the feeding trough.
