Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of poultry feeding, and particularly relates to an automatic feeding device for laying hens. BACKGROUND

[0002] In order to better feed, laying hens are mainly raised in cages. At present, large-scale laying hen farms use automatic feeding systems to realize automatic feeding of feed. The system uses a feeding trolley to realize automatic feeding function by automatic movement on the ground rail and the overhead rail, which greatly reduces the labor cost of feeding. However, the system needs to be installed when the henhouse is built, and the feeding trolley cannot be disassembled. All cages need to be built according to the unified plan, and each row of henhouses needs to be equipped with a set of rails and feeding trolleys. Therefore, the construction requirements are relatively harsh and the construction cost is high. However, many old henhouses are limited by environmental conditions and funding levels, and cannot install the existing automatic feeding system. In addition, the upper and lower placement methods of the cages in the henhouse are different, which causes the distance between the feeding port of the feeding trolley and the feeding trough to be unmatched.

[0003] Therefore, for the built henhouse, how to carry out automatic transformation to improve the feeding efficiency is one of the problems to be solved at present. SUMMARY

[0004] The technical problem to be solved by the application is to provide an automatic feeding device for laying hens, which can meet the installation requirements of different henhouse conditions and meet the purpose of automatic feeding.

[0019] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0020] like Figures 1 to 7 As shown, an automatic feed dispensing device for laying hens includes a track, a frame 1, and a feed box 2. The track is made of φ30mm-40mm round steel pipe and is fixedly installed outside the existing chicken house by pipe supports, located above the feed trough 35. Two tracks are installed: a lower track 3 installed in the bottommost chicken cage and an upper track 4 installed in the topmost chicken cage. Figure 6 and 7 As shown, chicken coops can be arranged in two ways: vertically stacked or tilted. Therefore, the upper rail 4 and lower rail 3 also result in two installation configurations: one where the plane containing the axis is perpendicular to the ground, and the other where the plane containing the axis is tilted to the ground.

[0021] The frame 1 is a square frame made of 50mm×50mm square steel tubing. The frame 1 is machined with grooves 5, through holes, and other structures for the installation of related components.

[0022] An adjustable linkage mechanism 6, a lifting device 7, and a feeding box 2 are installed on the frame 1. The adjustable linkage mechanism 6 is equipped with an upper traveling device 8 corresponding to the upper track 4 and a lower traveling device 9 corresponding to the lower track 3, and either the upper traveling device 8 or the lower traveling device 9 is equipped with a drive device 10. Since a farm may contain chicken cages of different sizes and arrangements, the adjustable linkage mechanism 6 adaptively adjusts the installation angle and adapts to tracks with different spacings, achieving seamless and adaptive installation of the entire device.

[0023] Specifically, such as Figures 1 to 4 As shown, the adjustable linkage mechanism 6 includes a rear swing frame 11, a front swing frame 12, a first telescopic mechanism 13, and a second telescopic mechanism 14.

[0024] Both the rear swing frame 11 and the front swing frame 12 are frames made of 50mm×50mm square steel tubing, and there are two rear swing frames 11 and two front swing frames 12, one above the other. The rear end of the lower rear swing frame 11 is fixedly hinged to the bottom of the frame 1 via a pivot, while the rear end of the upper rear swing frame 11 is slidably hinged to the upper part of the frame 1 in the slide groove 5 via a pivot. That is to say, the lower rear swing frame 11 can only swing back and forth around the fixed hinge point, while the upper rear swing frame 11 can swing back and forth around the sliding hinge point. This arrangement allows the spacing between the upper and lower rear swing frames 11 to be changed, thereby adapting to the installation requirements of tracks with different spacing.

[0025] The rear end of the lower front swing frame 12 is fixedly hinged to the front end of the corresponding rear swing frame 11, and the rear end of the upper front swing frame 12 is fixedly hinged to the front end of the corresponding rear swing frame 11. The two-section swing frame enables multi-angle adjustment of the frame 1.

[0026] To form a parallelogram mechanism, two copies of each of the first telescopic mechanism 13 and the second telescopic mechanism 14 are provided, one on the left and one on the right. The two ends of the two first telescopic mechanisms 13 are hinged to the hinge points on the left and right sides of the front ends of the two rear swing frames 11, respectively. The two ends of the two second telescopic mechanisms 14 are hinged to the middle of the left and right sides of the two front swing frames 12, respectively. In other words, the frame 1, the two rear swing frames 11, and the first telescopic mechanism 13 constitute a parallelogram mechanism, as do the first telescopic mechanism 13, the two front swing frames 12, and the second telescopic mechanism 14. This structure enables synchronous adjustment of the two rear swing frames 11 and the two front swing frames 12. Specifically, when the height of the upper rear swing frame 11 is changed, the first telescopic mechanism 13 and the second telescopic mechanism 14 automatically adjust their telescopic lengths. Similarly, when the angle of one set of rear swing frames 11 is changed, the angle of the other set of rear swing frames 11 automatically adjusts to maintain parallelism between the two sets of rear swing frames 11. Similarly, when one set of front swing arms 12 is changed, the other set of front swing arms 12 also adjusts its angle accordingly to keep both sets of front swing arms 12 parallel to each other.

[0027] As a preferred embodiment, both the first telescopic mechanism 13 and the second telescopic mechanism 14 include an optical shaft and a linear bearing. The diameter of the optical shaft is 20mm-30mm. The linear bearing is hinged and mounted via a hinge support 15. One end of the optical shaft is hinged and mounted via the hinge support 15, and the other end passes through the linear bearing to form a sliding assembly, thereby achieving adaptive adjustment through the telescopic function of the telescopic mechanism.

[0028] In another embodiment, the first telescopic mechanism 13 and the second telescopic mechanism 14 may also be telescopic rods with spline connections.

[0029] Since the rear swing frame 11 and the front swing frame 12 are adjusted synchronously, only one of the rear swing frame 11 or the front swing frame 12 needs to be fixed to fix their angles. Therefore, at least one rear swing frame 11 adjusts its installation angle with the frame 1 through the first locking mechanism 16, and at least one front swing frame 12 adjusts its installation angle with the rear swing frame 11 through the second locking mechanism 17. In this example, the lower rear swing frame 11 adjusts its angle through the first locking mechanism 16, and the lower front swing frame 12 adjusts its angle through the second locking mechanism 17.

[0030] like Figure 2As shown, as a preferred example, the first locking mechanism 16 includes a first locking plate 18 and a first locking bolt 19. The first locking plate 18 is fixedly mounted on the rear swing frame 11 located below. The first locking plate 18 is an arc-shaped structure and is provided with a first arc groove 20. The center of the first arc groove 20 is coaxial with the rear hinge axis of the rear swing frame 11. The first locking bolt 19 is mounted on the frame 1 and is connected to the first arc groove 20.

[0031] The second locking mechanism 17 includes a second locking plate 21 and a second locking bolt 22. The second locking plate 21 is fixedly mounted on the lower rear swing frame 11. The second locking plate 21 is an arc-shaped structure and has a second arc groove 23. The center of the second arc groove 23 is coaxial with the rear hinge shaft of the rear swing frame 11. The second locking bolt 22 is mounted on the rear swing frame 11 and engages with the second arc groove 23. The angle of the swing frame can be changed by adjusting and fixing the position of the locking bolt in the arc groove.

[0032] The upper traveling device 8, the lower traveling device 9, and the drive device 10 are respectively installed at the front end of the corresponding front swing frame 12. That is, either the upper traveling device 8 or the lower traveling device 9 is driven by the drive device 10 to move the whole along the track. As a preferred example, when the upper traveling device 8 is equipped with the drive device 10, it includes an upper traveling wheel 24 and a clamping wheel 25, and the drive device 10 drives the upper traveling wheel 24. When the lower traveling device 9 is equipped with the drive device 10, it includes a lower traveling wheel 26 and a clamping wheel 25, and the drive device 10 drives the lower traveling wheel 26. There are two upper traveling wheels 24 and two lower traveling wheels 26, and the clamping wheel 25 is located below between the two traveling wheels. The drive device 10 includes a drive pulley, a drive motor 27, and a belt transmission mechanism 28. The main shaft of the drive motor 27 is equipped with a drive pulley, which is connected to the two traveling wheels through the belt transmission mechanism 28, thereby realizing movement on the track under the drive of the drive motor 27. Both the traveling wheel and the clamping wheel 25 are grooved wheels with "V" grooves. The "V" grooves form a positioning fit with the track surface to achieve the function of straight-line travel.

[0033] like Figure 4As shown, in a preferred embodiment, the clamping wheel 25 is mounted on the front end of the corresponding front swing frame 12 via an adjustable wheel seat 29. The height of the adjustable wheel seat 29 is adjusted by an adjustable bolt 30, thereby enabling the clamping wheel 25 to be fixed and disassembled from the track. The clamping wheel 25 is positioned opposite to the traveling wheel on the corresponding front swing frame 12; that is, when the traveling wheel is above the track, the clamping wheel 25 is below the track, thus firmly clamping the track and ensuring stability during movement. Obviously, the track can be a square tube or a round tube, adaptively matching the "V" grooves of the traveling wheel and the clamping wheel 25. The adjustable wheel seat 29 is fixedly provided with the adjustable bolt 30, and the front end of the front swing frame 12 has a through hole through which the adjustable bolt 30 passes from bottom to top. A nut is provided on the portion of the adjustable bolt 30 extending out of the through hole, thereby fixing the position of the adjustable wheel seat 29 on the front swing frame 12.

[0034] The feeding box 2 is slidably mounted on the frame 1 via guide rods 31 and linear bearings, and is connected to the movable end of the lifting mechanism, thus rising and falling under the drive of the lifting device 7. The guide rods 31 are symmetrically and vertically mounted on the frame 1, and the feeding box 2 can move up and down along the axis of the guide rods 31 to match feeding troughs 35 of different heights. It should be noted that when the distance between the discharge port 34 of the feeding box 2 and the feeding trough 35 is large, potentially preventing all feed from falling into the feeding trough 35, a feed channel can be added to the discharge port 34 to ensure all feed falls into the feeding trough 35, reducing waste.

[0035] As a preferred embodiment, the lifting device 7 includes a lifting motor 32 and a lead screw mechanism 33. The lifting motor 32 is mounted on the top of the frame 1, and the lead screw mechanism 33 is vertically rotatably mounted on the frame 1, with its top end connected to the main shaft of the lifting motor 32. The feeding box 2 is connected to the nut of the lead screw mechanism 33. After the lifting motor 32 operates, it drives the feeding box 2 to rise and fall, thereby achieving the feeding requirements of different layers. The front end of the feeding box 2 is provided with an inclined discharge port 34, from which feed can be discharged and fall into the feeding trough 35.

[0036] like Figure 6 and Figure 7As shown, move the feeding box 2 to a suitable height to ensure that the discharge port 34 is aligned with the feeding trough 35. Then, pour the feed into the feeding box 2 and hold the baffle to block the discharge port 34. Then, start the drive motor 27 to move the entire device along the track. At this time, the discharge port 34 is no longer blocked by the baffle, and the feed falls from the feeding box 2 into the feeding trough 35, realizing automatic feeding. As a feeding mode, in this mode, the amount of feed in the feeding box 2 is just enough to feed the feeding trough 35 of one layer of chicken cages. When the feeding trough 35 of one layer of chicken cages is full, the device resets and adjusts the feeding box 2 to a suitable height, so as to feed the feeding trough 35 of another layer of chicken cages again. It should be noted that when the feeding box 2 is in the initial position, a baffle is set in the initial position to block the discharge port 34. When the feeding box 2 starts to move and the discharge port 34 leaves the baffle, the discharge port 34 opens and begins to sprinkle feed into the feeding trough 35. As another feeding mode, in this mode, the amount of feed in the feeding box 2 is sufficient to feed the troughs 35 of the multi-layer chicken cage. When one trough 35 is full, the feeding box 2 directly changes its height to the height of the corresponding trough 35, and then the device moves in the opposite direction to feed. When the height of the feeding box 2 changes, a baffle is also provided at the end to prevent feed from being discharged from the outlet 34 during height adjustment, thus avoiding waste. Obviously, the angle of the baffle and the end face angle of the feeding port are parallel to the lifting and lowering adjustment direction of the feeding box 2, thereby ensuring that the outlet 34 is blocked by the baffle during height adjustment.

[0037] It should be noted that the electrical components in this device need to be controlled by a controller and powered by a power supply, which is existing technology and will not be described in detail here.

[0038] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
