Abstract
Description
Technical Field
[0001] This invention relates to the field of livestock and poultry feeding equipment technology, specifically to a layered feeding device for preventing damage to vegetable leaves in a livestock farm. Background Technology
[0002] In the process of large-scale livestock and poultry farming, vegetable leaves, as a widely available, low-cost, and nutritious green fodder, are widely used in the feeding of poultry, rabbits, and other farmed species to supplement the vitamins and dietary fiber needed for the growth of farmed animals and improve the quality and taste of farmed products. Currently, farms commonly use a centralized, piled-up feeding method for vegetable leaves, directly dumping them into feeding troughs or hoppers for animals to freely graze on. This method makes it easy for animals to trample and disturb the leaves, causing large amounts to fall to the ground and become contaminated by feces and wastewater. This not only results in a significant waste of green fodder but also greatly increases the risk of animals ingesting contaminated feed and developing digestive diseases. To reduce leaf spillage, some farms pre-chop the leaves before feeding. While this reduces spillage to some extent, it increases the cost of chopping equipment and labor. Furthermore, chopping damages the plant tissue, drastically shortening the shelf life and making the leaves prone to overheating and rotting, thus hindering long-term continuous feeding.
[0003] While some tiered feeding devices have emerged in the existing technology, most of these devices are designed for granular concentrates and powdered compound feeds. They do not take into account the characteristics of whole, untreated vegetable leaves, such as their brittle texture, fragility, scattering, and tendency to rot due to water accumulation. They also do not incorporate the natural feeding habits of farmed animals into their structural design. They mostly adopt a top-down feeding logic, and the animals will still disturb the upper layer of feed during feeding, causing vegetable leaves to fall and become contaminated. This cannot fundamentally solve the problem of loss during vegetable leaf feeding. Furthermore, they cannot meet the support and feeding needs of whole, untreated vegetable leaves, making it difficult to meet the stable feeding requirements of low-cost, low-loss green fodder in large-scale farms. Summary of the Invention
[0004] The present invention aims to provide a layered feeding device for preventing damage to vegetable leaves in aquaculture farms, so as to solve the problems of high feed loss rate, high feeding cost and short preservation period of existing vegetable leaf feeding methods.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a layered feeding device for preventing damage to vegetable leaves in a farm, comprising a support base, a vertical support rod, and at least two layers of vegetable leaf support trays. The vertical support rod is fixedly installed on the upper surface of the support base. The vegetable leaf support trays of each layer are arranged sequentially from bottom to top along the height direction of the vertical support rod. The vegetable leaf support trays are used to support whole vegetable leaves that have not undergone shredding or pretreatment. The supporting surface of each layer of vegetable leaf support trays is horizontally arranged facing the feeding direction of the farmed animals. The vertical spacing between two adjacent layers of vegetable leaf support trays is adapted to the standing feeding height of the target farmed animals.
[0006] The principle of this solution is as follows: Multiple layers of vegetable leaf support trays are spaced out from bottom to top using vertical support rods, forming a layered support structure adapted to the whole vegetable leaves. Utilizing the tendency of farmed animals to preferentially feed from lower levels, the system guides them to feed in an orderly manner from bottom to top. The feeding process only disturbs the current layer of vegetable leaves, preventing upper layers from falling and contaminating them. Water accumulated on the surface of the vegetable leaves drains through conical drainage holes into a collection trough at the bottom, preventing the leaves from rotting due to water accumulation. Feeding can be completed without pre-treating the vegetable leaves by chopping them.
[0007] Advantages of this solution: 1. The bottom-up, tiered feeding design prevents vegetable leaves from falling, being trampled, and contaminating the feed, reducing feed loss. 2. It can directly support whole, untreated vegetable leaves, eliminating the need for chopping and pre-treatment equipment and labor, thus reducing feeding costs. 3. The conical drainage holes and water collection trough quickly drain surface water from the leaves, and the tiered ventilation structure extends the shelf life of the vegetables. 4. The anti-falling baffles prevent leaves from being pulled out of the tray, further reducing feed loss and adapting to the actual feeding scenarios of farms.
[0008] Preferably, as an improvement, at least three vertical support rods are provided, the bottom end of each vertical support rod is fixedly connected to the upper end face of the bearing base, each vertical support rod is evenly distributed along the circumference of the bearing base, the edge of the vegetable leaf bearing tray is detachably and fixedly connected to each of the vertical support rods, and the connection position between the vegetable leaf bearing tray and the vertical support rods can be adjusted along the height direction of the vertical support rods.
[0009] Preferably, as an improvement, the supporting surface of the vegetable leaf support tray is provided with multiple sets of conical drainage holes, the conical drainage holes are arranged through the thickness direction of the vegetable leaf support tray, and the diameter of the conical drainage holes gradually decreases in the downward direction of the supporting surface.
[0010] Preferably, as an improvement, the bottom of the conical drain hole is connected to a water collection trough, which is detachably installed on the lower end face of the vegetable leaf support tray, and the coverage of the water collection trough matches the layout range of all the conical drain holes.

[0017] The following detailed description illustrates the specific implementation method: The basic implementation examples are as follows: Figure 1 As shown: A layered feeding device for preventing damage to vegetable leaves in a farm includes a support base 3, three vertical support rods 1, and three layers of vegetable leaf support trays 2. The support base 3 is a circular plate structure. The bottom ends of the three vertical support rods 1 are fixedly connected to the upper end face of the support base 3. The three vertical support rods 1 are evenly distributed along the circumference of the support base 3 to form a stable triangular support structure.
[0018] The three-layer vegetable leaf support tray 2 is arranged sequentially from bottom to top along the height direction of the vertical support rod 1, with a vertical spacing of 25cm between two adjacent layers of vegetable leaf support tray 2, which is suitable for the standing feeding height of the target farmed animals. The edges of the vegetable leaf support tray 2 and the three vertical support rods 1 can be detachably and fixedly connected. The connection position between the vegetable leaf support tray 2 and the vertical support rod 1 can be adjusted along the height direction of the vertical support rod 1. The supporting surface of the vegetable leaf support tray 2 is set horizontally upward, and is used to support whole vegetable leaves that have not been chopped or pre-treated.
[0019] The supporting surface of the vegetable leaf support tray 2 is a slightly arc-shaped structure with an upward convex shape. Multiple sets of conical drainage holes 7 are provided on the supporting surface. The conical drainage holes 7 are arranged through the thickness direction of the vegetable leaf support tray 2. The diameter of the conical drainage holes 7 gradually decreases in the downward direction of the supporting surface. The bottom of the conical drainage holes 7 is connected to a water collection trough 5. The water collection trough 5 can be detachably installed on the lower end face of the vegetable leaf support tray 2. The coverage area of the water collection trough 5 matches the layout area of all the conical drainage holes 7, and is used to collect the water on the surface of the vegetable leaves that drains from the conical drainage holes 7.
[0020] The vegetable leaf support tray 2 has an integrally formed anti-drop baffle 6 on the edge of the support surface. The anti-drop baffle 6 is arranged in a closed loop around the support surface of the vegetable leaf support tray 2, and the anti-drop baffle 6 is inclined inward on the side facing the center of the support surface.
[0021] Four universal moving rollers 4 with brake structure are installed on the lower end face of the support base 3. The four universal moving rollers 4 are evenly distributed along the circumference of the support base 3. The support base 3, the vertical support rod 1 and the vegetable leaf support tray 2 are all made of food-grade stainless steel.
[0022] The specific implementation process is as follows: Before feeding the vegetable leaves, adjust the fixed position of each layer of vegetable leaf support tray 2 on the vertical support rod 1 according to the species, growth stage and standing feeding height of the target farmed animals, and determine the vertical spacing between two adjacent layers of vegetable leaf support tray 2 to ensure that the spacing is adapted to the feeding habits of the farmed animals; then, the harvested whole vegetable leaves, without any chopping or pre-treatment, are directly and evenly spread on the support surface of each layer of vegetable leaf support tray 2; then, the device is pushed to the target feeding area of the farm by the universal moving roller 4 at the lower end of the support base 3, and the braking structure of the universal moving roller 4 is locked to complete the position fixation of the device.
[0023] During feeding, farmed animals, based on their natural feeding habits, prioritize contacting and consuming the vegetable leaves in the bottommost vegetable leaf support tray 2. After the bottommost vegetable leaves are completely consumed, they gradually consume the vegetable leaves in the upper vegetable leaf support tray 2, achieving orderly layered feeding from bottom to top. During feeding, excess water on the surface of the vegetable leaves is guided by the slightly arc-shaped support surface of the vegetable leaf support tray 2 and discharged into the water collection trough 5 below through the conical drainage holes 7, preventing the vegetable leaves from being soaked in water for a long time and rotting. The anti-drop baffle 6 can prevent farmed animals from pulling the vegetable leaves out of the vegetable leaf support tray 2 during feeding, further reducing the loss of vegetable leaves.
[0024] After a single batch of feeding is completed, the vegetable leaf carrying tray 2 can be completely removed from the vertical support rod 1, and the water collection trough 5 can be removed from the bottom of the vegetable leaf carrying tray 2 for thorough rinsing and disinfection. After drying, it can be reused.
