Description

Technical Field

[0001] This utility model relates to the field of cricket breeding technology, specifically a cricket breeding feeding tray. Background Technology

[0002] In current cricket farming practices, shallow, flat-bottomed trays are commonly used for feeding. During feeding, the crickets' feces and food residue mix with uneaten fresh feed. This mixing leads to: 1. Microbial growth: Feces provide a breeding ground for pathogenic microorganisms (such as bacteria and fungi), contaminate feed, and significantly increase the risk of disease in crickets.

[0003] 2. Feed waste: Contaminated feed has reduced palatability, and crickets refuse to eat it, resulting in huge waste.

[0004] 3. High labor costs: Frequent feed changes and cleaning of feeding trays are required.

[0005] Therefore, it is necessary to propose a cricket breeding feeding tray to solve the above problems. Utility Model Content

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] Example 1: This Example 1 provides a cricket breeding feeding tray, which is a direct improvement on existing feeding trays. It has a unique structure. Please refer to [link / reference]. Figure 1 , 2 As shown in Figure 5, the device includes a frame 1, on the top of which a feeding tray 2 is placed. The frame 1 is a rectangular frame, and the outer side of the top of the feeding tray 2 is provided with a ring platform. The outer edge of the ring platform is flush with the outer edge of the frame 1, which facilitates cleaning of the feeding tray 2. Both the frame 1 and the feeding tray 2 are made of stainless steel, which extends their service life.

[0020] The vertical height of the feed trough in the feeding tray 2 is set at 1cm. This height can meet the normal feeding needs of cricket larvae, nymphs and adults, and can also effectively prevent crickets from throwing pellets or powdered feed out of the tray when they are scrambling, thus reducing feed waste. The bottom of the feeding tray 2 is evenly provided with perforated holes 3. The diameter of the perforated holes 3 is precisely calculated and screened, and its size threshold is strictly controlled within the range of "feed pellets cannot pass through, and small debris produced by crickets scrambling can pass through smoothly". The specific hole diameter can be adapted and adjusted according to the average particle size of the feed used for breeding, and is usually between 0.3mm and 0.8mm.

[0021] A pull-out window 4 is provided on one side of the lower part of the frame 1. The size of the pull-out window 4 is adapted to the outer circumference of the collection tray 6, ensuring that the collection tray 6 can be smoothly pulled out or pushed in. The collection tray 6 is provided below the feeding tray 2. The collection tray 6 is made of stainless steel plate and is stamped in one piece. The upper part of its four side walls is integrally formed with a stepped structure. Support plates 5 are fixedly installed on the inner walls of the frame 1 on both sides of the pull-out window 4. The collection tray 6 is placed on the two support plates 5 to achieve a sliding connection with the frame 1. The collection tray 6 is provided with a screen 7. The screen 7 is clamped in the enclosed area formed by the four steps, dividing the collection tray 6 into two independent areas, the upper area for temporarily storing recyclable feed scraps and the lower area for collecting cricket feces.

[0022] The screen 7 is equipped with three different aperture sizes: 0.5mm, 1mm, and 2mm. These sizes can precisely match the differences in fecal particle size among the three growth stages of crickets: larvae, nymphs, and adults. Larval fecal particles are usually less than 0.5mm in diameter, and a 0.5mm aperture screen can completely separate fecal particles from feed debris during the larval stage. Nymphal fecal particles are between 0.5mm and 1mm in diameter, and a 1mm aperture screen can effectively trap uneaten feed fragments at this stage. Adult fecal particles can reach 1mm to 1.8mm in diameter, and a 2mm aperture screen can ensure that fecal particles fall smoothly while preventing the loss of larger feed debris generated by adult feeding.

[0023] Sloping plates 9 are hinged to the frames 1 on both sides of the sliding window 4. Connecting plates 8 are fixedly installed on the frames 1 on both sides of the sloping plates 9. The upper end of the sloping plate 9 is bent downward to form a ring structure. A rotating shaft 10 is movably fitted inside the ring. The other ends of the two rotating shafts 10 are fixedly connected to the connecting plates 8 on the adjacent sides. This hinge structure makes the sloping plate 9 easy to disassemble. The angle between the sloping plate 9 and the side wall of the frame 1 is set at 30 degrees. This angle is the optimal inclination angle for crickets to crawl, which reduces the difficulty of crawling and prevents crickets from falling due to excessive angle. The sloping plate 9 is made of rubber, plastic or stainless steel plate with a rough surface treatment. Specifically, the surface friction coefficient can be increased by sandblasting process, which makes it easier for crickets to crawl from the ground of the breeding environment along the sloping plate 9 to the feed trough of the feeding tray 2 to eat.

[0024] Working principle: The screen 7 corresponding to the breeding stage is attached to the step of the collection tray 6, and then the collection tray 6 is placed on the support plate 5 through the pull-out window 4. Pelleted feed is added to the feed trough of the feeding tray 2. The crickets climb up the inclined plate 9 to the feed trough to feed. During the feeding process, the feed scraps and excrement produced by scratching are smaller than the diameter of the holes 3 and fall onto the screen 7 through the holes 3. Under the screening action of the screen 7, the excrement with smaller particle size passes through the screen 7 and falls into the lower area of ​​the collection tray 6, while the feed scraps are trapped in the upper area of ​​the screen. During routine maintenance, the collection tray 6 only needs to be pulled out through the pull-out window 4 to clean the feed scraps on the screen 7 that can be recycled and the excrement in the lower area. The whole process does not require disturbing the feed and crickets in the feeding tray 2, which greatly reduces the impact of breeding operations on the growth of crickets.

[0025] Example 2: Based on Example 1, this example further optimizes the separation effect of debris and feces, such as... Figure 4 and 6 As shown, it also includes a swaying mechanism disposed on both sides of the pull-out window 4. The swaying mechanism includes a drive assembly disposed between the inclined plate 9 and the frame 1, and an airbag 17 disposed between the support plate 5 and the collection tray 6.

[0026] The drive assembly includes a fixed cylinder 11 fixedly mounted on the side wall of the frame 1. The fixed cylinder 11 is a cylindrical structure with open ends. A piston 12 is slidably fitted inside the fixed cylinder 11. The outer peripheral wall of the piston 12 is tightly fitted with the inner wall of the fixed cylinder 11 to ensure sealing performance. A limit ring is fixedly fitted on the inner side of the end of the fixed cylinder 11 away from the frame 1. The inner diameter of the limit ring is smaller than the outer diameter of the piston 12 to limit the sliding stroke of the piston 12 and prevent the piston 12 from coming out of the fixed cylinder 11. A spring 13 is provided on the side of the piston 12 near the frame 1. One end of the spring 13 abuts against the side wall of the frame 1, and the other end is fixedly connected to the piston 12. In the initial state, the spring 13 is in a naturally extended state, causing the piston 12 to drive the connecting rod 14 to extend away from the frame 1.

[0027] A connecting rod 14 is fixedly installed on the other side of the piston 12. The axis of the connecting rod 14 coincides with the axis of the fixed cylinder 11. A ball 15 is fixedly installed at the other end of the connecting rod 14. The ball 15 is made of hard rubber, which has a certain structural strength and can reduce the wear on the inclined plate 9. The ball 15 abuts against the middle area of ​​the inclined plate 9 to ensure that the inclined plate 9 can effectively transmit pressure when it is subjected to force. The airbag 17 is made of elastic rubber. Its top fits tightly against the bottom of the collection plate 6, and its bottom is fixedly installed on the support plate 5. An air tube 16 is fixedly installed at the bottom of the airbag 17. The air tube 16 is a flexible pressure-resistant tube. Its other end passes through the support plate 5 and the frame 1 in sequence and communicates with the inside of the fixed cylinder 11 to realize the air passage connection between the fixed cylinder 11 and the airbag 17.

[0028] The working principle of this embodiment is further optimized based on embodiment 1: Initially, under the action of spring 13, the lower end of the inclined plate 9 is about 1-2mm away from the ground, which allows the cricket to climb onto the inclined plate 9 and also allows the inclined plate 9 to move. When the cricket climbs on the two inclined plates 9, its weight will exert downward pressure on the inclined plate 9, causing the inclined plate 9 to rotate along the pivot 10 towards the frame 1, thereby squeezing the ball 15. After the ball 15 is subjected to force, it pushes the connecting rod 14 to drive the piston 12 to move towards the frame 1, the spring 13 is compressed, and at the same time, the air in the fixed cylinder 11 is forced into the air bladder 17 through the air pipe 16, causing the air bladder 17 to expand and lift the corresponding end of the collection plate 6.

[0029] As the number of crickets on the two inclined plates 9 changes constantly with their feeding behavior (some crickets crawl away, some crawl in), the squeezing force of the two inclined plates 9 on the sphere 15 changes in real time, which in turn causes the degree of expansion of the two air bladders 17 to change alternately. When the expansion of the left air bladder 17 is greater than that of the right, the left end of the collecting plate 6 rises and the right end falls; when the expansion of the right air bladder 17 is greater than that of the left, the right end of the collecting plate 6 rises and the left end falls, ultimately achieving the back-and-forth change in the height of the two ends of the collecting plate 6, producing a continuous shaking effect.

[0030] This shaking action can fully disperse the feed debris and feces falling on the screen 7, preventing them from clumping together due to moisture or stickiness, which would lead to incomplete screening and significantly improve separation efficiency. The entire process does not require additional energy and is achieved entirely by the crickets' own activities, meeting the needs of energy-saving farming.

[0031] Example 3: This example further improves the stability and safety of the device operation based on Example 2, such as... Figure 3 and 6 As shown, it also includes a limiting component set above the pull-out window 4 to prevent the collection tray 6 from sliding out of the pull-out window 4 due to inertia when it shakes left and right.

[0032] The limiting component includes a U-shaped plate 18 fixedly installed on the frame 1. The opening of the U-shaped plate 18 faces the pull-out window 4, and its two ends are fixedly connected to the outer side wall of the frame 1. The U-shaped plate 18 and the frame 1 together form a vertically extending enclosed area. An insert plate 20 is slidably fitted vertically within this enclosed area. The thickness of the insert plate 20 is adapted to the width of the enclosed area to ensure smooth sliding without significant shaking. A fixing plate 19 is fixedly installed at the upper end of the insert plate 20. The lateral dimension of the fixing plate 19 is larger than the opening width of the U-shaped plate 18, which is used to limit the maximum downward stroke of the insert plate 20 and prevent the insert plate 20 from falling out of the enclosed area. The lower end of the insert plate 20 extends to the lower part of the pull-out window 4, and its length can be adjusted according to the height of the pull-out window 4 to ensure that after the insert plate 20 is inserted, its lower end can form abutment or limiting cooperation with the upper side wall of the collection tray 6.

[0033] The usage process of this embodiment is as follows: After pushing the collection tray 6 into the frame 1, push the fixing plate 19 downward, causing the insert plate 20 to slide down along the enclosed area formed by the U-shaped plate 18 and the frame 1 until the lower end of the insert plate 20 extends to the lower part of the pull-out window 4 and corresponds to the outer wall of the collection tray 6; at this time, even if the collection tray 6 shifts towards the pull-out window 4 during shaking, it will be blocked by the insert plate 20, effectively preventing it from falling out of the pull-out window 4; when it is necessary to remove the collection tray 6 for cleaning, pull the fixing plate 19 upward, causing the insert plate 20 to slide upward, so that the lower end of the insert plate 20 is separated from the pull-out window 4 area, and the collection tray 6 can be easily removed. The operation is convenient and does not affect the normal maintenance of the device; by adding a limiting component, the risk of the collection tray 6 falling off when shaking in Embodiment 2 is effectively solved, and the structural reliability of the device is further improved.
