Description

Technical Field

[0001] This utility model relates to the field of feed feeding trolley technology, specifically to an adjustable-height laying hen feeding trolley and its anti-spillage structure. Background Technology

[0002] In traditional egg-laying hen farming, feeding is a crucial step in ensuring the healthy growth and high egg production of hens, but it has long faced numerous challenges. In the early days, egg-laying hen farming primarily relied on manual feeding, requiring farmers to manually add feed to each cage by hand. This method was not only extremely labor-intensive and inefficient, but also made it difficult to precisely control the amount of feed added, often resulting in some troughs overflowing and wasting feed, while others were underfeeding, affecting the hens' appetite.

[0003] With the expansion of poultry farming, automated feeding equipment is increasingly being used. However, most existing automated feeding trolleys have fixed structures and non-adjustable heights. Because the heights of tiered layer hen cages vary across different farms, and even within the same farm, cage heights can differ in different areas due to terrain and design factors, fixed-height feeding trolleys cannot adequately adapt to various farming environments. This leads to inaccurate feed dispensing, with some feed spilling outside the cages, resulting in waste and increased cleaning costs. Furthermore, existing feeding equipment lacks effective spill prevention designs during the feeding process. When feed is poured from the hopper through the dispensing pipe, it is easily deviated from the feed trough due to airflow and equipment vibration, further exacerbating feed waste and impacting the economic benefits of poultry farming. Therefore, developing an adjustable-height layer hen feeding trolley with spill prevention features is essential. Utility Model Content

The following description is merely exemplary and not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these drawings, the same or similar reference numerals indicate the same or similar parts and features. The various drawings only schematically illustrate the concept and principle of the embodiments of this disclosure and do not necessarily show the specific dimensions and proportions of the various embodiments of this disclosure. The technical solution of this utility model will be clearly and completely described below in conjunction with embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model.

[0027] Example 1: An adjustable-height layer hen feeding trolley includes a traveling mechanism 1, a height adjustment mechanism 2 connected to the top of the traveling mechanism 1, and a hopper mechanism 4 installed on the top of the height adjustment mechanism 2. In the traveling mechanism 1, the trolley track 1-1 is fixed between the stepped layer hen cages, the trolley motor 1-2 is movably positioned inside the trolley track 1-1, and the support frame 1-3 is fixed to the top surface of the trolley motor 1-2. The top end of the support frame 1-3 is fixedly connected to the bottom surface of the square groove 2-2 by bolts. In the height adjustment mechanism 2, four movable square columns 2-1 move vertically inside the four square grooves 2-2, and two hydraulic cylinders 2-3 are positioned between the square grooves 2-2. The bottom surface of the hydraulic cylinders 2-3 is fixed to the upper surface of the support frame 1-3, and the telescopic end is fixedly connected to the bottom surface of the rectangular steel frame 4-1. The maximum extension stroke of the hydraulic cylinders 2-3 is less than the maximum extension stroke of the movable square columns 2-1 inside the square grooves 2-2. In the hopper mechanism 4, four hoppers 4-2 are fixed inside the rectangular steel frame 4-1. Three feed pipes 4-3 are arranged in a stepped manner at the bottom of each hopper 4-2, with the bottom ends of the feed pipes 4-3 facing the feed trough at the front of the stepped layer hen cage. The top end of the movable square column 2-1 is fixedly connected to the bottom surface of the rectangular steel frame 4-1. This feeding trolley is also equipped with an anti-spillage structure. The clamp 3-1 of the anti-spillage component 3 is clamped at the bottom of the outer surface of the feed pipe 4-3. The connecting column 3-2 is fixed to the side wall of the clamp 3-1, and the inclined plate 3-4 is fixed to the end of the connecting column 3-2. An arc-shaped plate 3-3, arranged symmetrically in a mirror image, is fixed to both the front and rear sides of the inclined plate 3-4. Both the arc-shaped plate 3-3 and the inclined plate 3-4 are inclined to guide the feed poured from the feed pipe 4-3 into the feed trough. In use, the overhead crane 1-2 moves on the overhead crane track 1-1, driving the entire feeding crane to move. According to the height of the laying hen cage, the height of the hopper mechanism 4 is adjusted by the extension and retraction of the hydraulic cylinder 2-3. The feed in the hopper 4-2 is discharged through the feed pipe 4-3, and the anti-spillage component 3 prevents the feed from spilling out.

[0028] Example 2: An adjustable-height feeding trolley for laying hens, with the same structure as Example 1. The traveling mechanism 1's track 1-1 is securely installed between the stepped laying hen cages. The trolley 1-2 moves smoothly back and forth within the track 1-1. The support frame 1-3 provides stable support for the height adjustment mechanism 2. In the height adjustment mechanism 2, the movable square column 2-1 moves flexibly up and down within the square groove 2-2. The hydraulic cylinder 2-3 provides power to adjust the height of the hopper mechanism 4. The rectangular steel frame 4-1 of the hopper mechanism 4 supports four hoppers 4-2. Four feed pipes 4-3 are installed at the bottom of the hoppers 4-2, with the feed pipes 4-3 accurately facing the feed trough. In the anti-spillage structure, the clamp 3-1 tightly clamps the feed pipes 4-3, the connecting column 3-2 connects to the inclined plate 3-4, and the arc plate 3-3 cooperates with the inclined plate 3-4 to guide the feed. In actual farm use, the feeding trolley can quickly adjust the height of the hopper mechanism 4 according to the height of the laying hen cages in different areas through hydraulic cylinders 2-3, so that the feed pipe 4-3 is in a suitable position. The trolley motor 1-2 drives the feeding trolley to move, so as to achieve uniform feeding. The anti-spillage component 3 effectively avoids feed waste.

[0029] Example 3: An adjustable-height feeding trolley for laying hens, comprising a traveling mechanism 1, a height adjustment mechanism 2, and a hopper mechanism 4. In the traveling mechanism 1, a trolley track 1-1 is installed between stepped laying hen cages, and the trolley machine 1-2 moves flexibly on the track. A support frame 1-3 connects to the height adjustment mechanism 2. In the height adjustment mechanism 2, four movable square columns 2-1 slide within square grooves 2-2, and two hydraulic cylinders 2-3 work together to adjust the height, ensuring that the maximum extension stroke of the hydraulic cylinders 2-3 is less than the maximum extension stroke of the movable square columns 2-1 within the square grooves 2-2. The rectangular steel frame 4-1 of the hopper mechanism 4 fixes four hoppers 4-2, and the bottom has three stepped feed pipes 4-3 aligned with the feed trough. It is also equipped with an anti-spillage structure; clamps 3-1 are fixed to the bottom of the feed pipes 4-3, and connecting columns 3-2 connect to inclined plates 3-4. The arc-shaped plate 3-3 and the inclined plate 3-4 are inclined. During the egg-laying hen breeding process, according to the growth stage of the egg-laying hens and the changes in the height of the breeding cage, the hydraulic cylinder 2-3 is controlled to extend and retract, so that the movable square column 2-1 moves in the square trough 2-2, driving the feed hopper mechanism 4 to rise and fall. The traveling machine 1-2 moves the feeding trolley. When feeding, the anti-spillage component 3 plays a role in preventing the feed from falling out of the feed trough and accurately falling into the feed trough.

[0030] Based on the above-described preferred technical solution, the workflow of this technical solution is explained as follows: Before use, the trolley track 1-1 is fixedly installed between the stepped layer chicken cages to provide a moving track for the entire feeding trolley. The trolley machine 1-2 is moved back and forth inside the trolley track 1-1, allowing it to move freely on the track. The support frame 1-3 is fixed to the top surface of the trolley machine 1-2, and the top end of the support frame 1-3 is fixedly connected to the bottom surface of the square groove 2-2 by bolts. This forms the connection foundation between the walking mechanism 1 and the height adjustment mechanism 2. In the height adjustment mechanism 2, four movable square columns 2-1 are moved up and down inside the four square grooves 2-2. Two hydraulic cylinders 2-3 are located between the square grooves 2-2, and the bottom surface of the hydraulic cylinders 2-3 is fixed to the upper surface of the support frame 1-3. The telescopic end is fixedly connected to the bottom surface of the rectangular steel frame 4-1. At the same time, the maximum extension stroke of the hydraulic cylinder 2-3 is less than that of the movable square column 4-1. The maximum extension stroke of column 2-1 inside square groove 2-2 provides a stable structure and stroke limit for subsequent height adjustment. The rectangular steel frame 4-1 of hopper mechanism 4 is connected to the height adjustment mechanism 2 by the top end of movable square column 2-1 and the bottom surface of rectangular steel frame 4-1. Four hoppers 4-2 are fixed inside rectangular steel frame 4-1. The bottom of hopper 4-2 is set with 3-4 feed pipes 4-3 in a stepped manner. The bottom ends of feed pipes 4-3 face the feed trough on the front side of stepped layer chicken cage, completing the basic assembly of the entire feeding trolley. For the anti-spillage structure, the clamp 3-1 of anti-spillage component 3 is clamped to the bottom of the outer ring surface of feed pipe 4-3. Connecting column 3-2 is fixed to the side wall of clamp 3-1. Inclined plate 3-4 is fixed to the end end of connecting column 3-2. An arc plate 3-3 is fixed on both the front and rear sides of inclined plate 3-4 in a mirror-symmetrical arrangement. Both arc plate 3-3 and inclined plate 3-4 are in an inclined state.

[0031] When the feeding trolley is in operation, the trolley 1-2 moves back and forth on the trolley track 1-1, moving the entire feeding trolley to the area where feeding is needed. Depending on the height of the laying hen cages in that area, the hydraulic cylinder 2-3 is activated. The telescopic end of the hydraulic cylinder 2-3 extends or retracts, causing the rectangular steel frame 4-1 to rise or fall. Because the top end of the movable column 2-1 is fixedly connected to the bottom surface of the rectangular steel frame 4-1, the movable column 2-1 moves up and down inside the square trough 2-2, adjusting the height of the hopper mechanism 4. When the hopper mechanism 4 is adjusted to a suitable height, ensuring the bottom end of the feed pipe 4-3 is accurately aligned with the feed trough, the hopper 4-... The feed in section 2 is poured downwards through the feed pipe 4-3. During the pouring process, if any feed deviates from the direction of the feed trough, the anti-spillage component 3 comes into play. Since the arc plate 3-3 and the inclined plate 3-4 are in an inclined state, and the clamp 3-1 fixes the entire anti-spillage component 3 to the bottom of the feed pipe 4-3, the poured feed will be guided into the feed trough along the inclined surfaces of the arc plate 3-3 and the inclined plate 3-4, avoiding feed spillage and waste. After the feeding of one area is completed, the crane 1-2 continues to move on the crane track 1-1, repeating the above-mentioned height adjustment and feeding operations until the feeding of the entire breeding area is completed.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
