A safety device to prevent chicken heads from getting stuck Technical Field
[0001] This utility model relates to the technical field of chicken farming, and in particular to a safety device for preventing chicken heads from getting stuck. Background Technology
[0002] With the development of my country's economy and the improvement of living standards, my country's chicken farming industry has developed rapidly. Chicken farms are places that specialize in poultry breeding. Nowadays, most chicken farms raise chickens in chicken cages. Chicken cages are mainly composed of cage bodies, egg troughs, and feed troughs. The cage body is an important part of the chicken cage, providing a safe and comfortable growth environment for the chickens. The cage body consists of front netting, top netting, bottom netting, side netting, and rear netting. The design of the front netting is very important. It needs to allow the chickens' heads to extend out to eat and drink. The existing front netting is a multi-mesh structure with horizontal bars and vertical bars forming a grid with a side length of about 4-6 cm. The size of the grid is fixed. When the chickens extend out of the front netting to eat and drink, their heads retract and extend rapidly, which can cause their heads to get stuck in the mesh. This is especially true when the chickens are frightened or exert sudden force, which makes head-stuckness more likely. In addition, due to the different sizes of chickens, chickens with large differences in size are also more likely to get their heads stuck.
[0003] Therefore, this application provides a safe anti-jamming device for chicken heads to solve the problems mentioned in the background art. Summary of the Invention

[0034] The present invention will be further explained below with reference to specific embodiments.
[0035] As shown in Figures 1-11, this embodiment provides a safety anti-stuck chicken head device, including a support frame 1, a feeding trough 2 on the support frame 1, a cage 3 behind the feeding trough 2, a front net 4 on the front side of the cage 3, a number of tubes 42 evenly fitted on the first horizontal bar 41 at the top of the front net 4, an inverted U-shaped part 43 on the bottom surface of the tube 42, the inverted U-shaped part 43 being axially connected to the top end of the longitudinal rod 44, a movable column 45 at the bottom end of the longitudinal rod 44, the two ends of the movable column 45 being respectively adapted to be inserted into the movable hole 46, the two movable holes 46 being symmetrically arranged on two horizontally parallel fixing plates 47, the two ends of the fixing plates 47 being fixed to the support frame 1, the movable column 45 moving left and right within the movable hole 46 to adjust the spacing between the longitudinal rods 44. The longitudinal rod 44 of this safety anti-stuck chicken head device is connected to the inverted U-shaped part 43 via the shaft rod 431, which allows for flexible left and right swinging. Combined with the lateral displacement allowance of the movable hole 46, the front net 4 forms a "flexible opening and closing" structure, which effectively prevents chickens from sticking their heads out of the front net when eating in the feed trough, and significantly reduces the risk of head stuck due to individual differences, being startled, or sudden force.
[0036] As shown in Figures 1, 2, 3, and 5-11, in this embodiment, the front net 4 further includes several second horizontal bars 48. The second horizontal bars 48 are positioned below the first horizontal bar 41, and both ends of the first horizontal bar 41 and the second horizontal bar 48 are connected to the side net 34. These second horizontal bars 48 are evenly distributed from top to bottom up to one-third of the height of the front net 4. This even distribution of the second horizontal bars 48 to one-third of the height of the front net 4 provides ample space for the chickens' heads to extend out for feeding and drinking. When the chickens are feeding, their heads can naturally pass through the gaps between the longitudinal bars 44 and extend downwards into the feeding trough without being obstructed by the unreasonable distribution of the horizontal bars. The first horizontal bar 41 protrudes forward relative to the second horizontal bar 48 by a distance equal to the diameter of the longitudinal bar 44, so that the longitudinal bar 44 is located in front of the second horizontal bar 48 and abuts against the second horizontal bar 48. A vertical n-shaped block 441 is provided at the top of the longitudinal rod 44. A through shaft hole 442 is provided in the middle of the n-shaped block 441. A shaft rod 431 is inserted into the shaft hole 442. The two ends of the shaft rod 431 are fixed to the two side walls of the inverted U-shaped part 43, respectively. The longitudinal rod 44 swings left and right around the shaft rod 431. The bottom end of the longitudinal rod 44 extends between two fixed plates 47. Multiple transverse movable holes 46 are evenly provided on the two fixed plates 47. A movable column 45 is inserted into the middle of the movable hole 46. The distance between the left and right sides of the movable column 45 and the left and right sides of the movable hole 46 is 5-10 mm. By moving the position of the movable column 45 in the movable hole 46 left and right, the spacing between the longitudinal rods 44 can be flexibly adjusted. The 5-10 mm distance limits the left and right swing range of the movable column 45, so that the spacing between the longitudinal rods 44 can remain relatively stable after adjustment. This design avoids excessive gaps between the movable column 45 and the movable hole 46, while ensuring that the longitudinal rod 44 can move smoothly when adjustment is needed, providing suitable extension space for the chicken's head and effectively reducing the risk of head entrapment. Mounting plates 471 are provided on the bottom surfaces of both ends of the two fixing plates 47, with through mounting holes 472 on the mounting plates 471. Bolts are used to screw the mounting holes 472 onto the support frame 1.
[0037] As shown in Figures 3 and 4, in this embodiment, the cage body 3 also includes a top net 32, a bottom net 33, a side net 34, and a rear cage door 31. The cage door 31 is provided on the rear side of the cage body 3. The top of the cage door 31 is hinged to the rear edge of the top net 32. A horizontal first locking plate 311 is provided on the outer bottom of the cage door 31. A second locking plate 331 is abutted against the lower part of the first locking plate 311. The side of the second locking plate 331 is fixed to the rear edge of the bottom net 33. Corresponding insertion holes 35 are provided on the first locking plate 311 and the second locking plate 331. An L-shaped plug 36 is inserted into the insertion hole 35. The cage door 31 is locked by the L-shaped plug 36 through the insertion hole of the first locking plate 311 and the second locking plate 331. The cage door can be quickly opened and closed without complicated tools, which is convenient for the breeder to catch chickens, clean up feces and disinfect, etc. The locking is firm and reliable, preventing chickens from escaping accidentally.
[0038] As shown in Figures 1 and 3, in this embodiment, the front side of the fixing plate 47 is set on the mounting frame 21, and the feeding trough 2 is set on the mounting frame 21. The front plate 22 of the feeding trough 2 is higher than the rear plate 23, which makes it easier for chickens to eat. The front plate 22 of the feeding trough 2 is higher than the rear plate 23, so that the feeding trough 2 is in an inclined state with the front higher and the rear lower. When the chickens eat, their heads can be inserted into the feeding trough 2 more naturally, without having to tilt their heads back or down excessively to adjust their posture, thus reducing energy consumption. The higher front plate has a certain limiting effect on the chickens' heads. When the chickens peck quickly or shake their heads, it can effectively prevent the food from being thrown out of the feeding trough, thus maintaining the concentration of food in the feeding trough.
[0039] This utility model also provides a working principle for a safety anti-stuck chicken head device: In use, the operator can pull out the L-shaped plug 36 on the first locking plate 311 and the second locking plate 331, rotate the cage door 31 hinged to the rear edge of the top net 32, put the chicken into the cage body 3, and then insert the L-shaped plug 36 into the first locking plate 311 and the second locking plate 331 to lock the cage door 31. When the chicken is eating, its head is lowered and passes through the longitudinal bars 44 located below the second crossbar 48. During feeding intervals, the longitudinal rod 44 is connected to the inverted U-shaped part 43 via the shaft 431, allowing the upper end of the longitudinal rod 44 to rotate around the shaft 431. The lower part cooperates with the movable column 45 and has a displacement margin of 5-10mm in the movable hole 46, so that the spacing of the longitudinal rod 44 can be dynamically adjusted with the extension and retraction of the chicken's head. This creates a "flexible opening and closing" structure at the lower part of the front net 4, effectively preventing the chicken from getting its head stuck while eating and significantly reducing the risk of head getting stuck due to individual differences, being startled, or sudden force.
[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
