Abstract
Description
Technical Field
[0001] This utility model relates to the field of egg production technology, and in particular to an experimental egg production performance evaluation device. Background Technology
[0002] The color, shape, and odor of laying hens' feces are directly related to their digestive system, metabolic function, and pathogen infection status. Fecal testing is a primary screening method for health monitoring, but it needs to be combined with clinical symptoms and laboratory tests for comprehensive judgment. After diagnosis, medication should be selected according to the type of pathogen (such as anticoccidial drugs, antibiotics, or antiviral agents), while simultaneously improving the environment and nutritional management to achieve precise treatment and recovery of production performance.
[0003] The condition of egg droppings is significantly correlated with the egg production of laying hens (including soft-boiled eggs, broken eggs, and the number of eggs laid). Therefore, corresponding drug treatments can be administered to address the symptoms of laying hens in order to ensure their production performance.
[0004] Traditional egg-laying hen farming often uses a three-dimensional cage system (40,000-100,000 hens / building). This group-based statistical approach cannot distinguish the egg-laying performance of individual cages or individual hens, and cannot accurately target individual hens with medication. As a result, low-producing hens (such as low-producing hens) are difficult to identify and remove, leading to waste.
[0005] To enable targeted drug treatment based on the feces and egg production (soft-shelled eggs, broken eggs, number of eggs, etc.) of laying hens, and to record the subsequent feces and egg production in a timely manner, thereby quickly obtaining an evaluation of veterinary medicine, an experimental laying hen production performance evaluation device is proposed.

[0013] As a further improvement to the above solution, an adjustment slot is provided in the middle of the outer wall of one side of the base. The adjustment slot consists of a vertical slot and a limiting slot. The vertical slot is located in the middle of the outer wall of the base, and a limiting slot is provided on one side of the upper end of the vertical slot.

[0025] The regulating mechanism is used to abut the winding bag 11, which is used to collect the manure from the two laying hens in the chicken cage, and the manure is quickly analyzed and recorded through the regulating mechanism.
[0026] An inclined base plate 3 is fixedly connected to the bottom of the chicken cage 2. The base plate 3 is located below the inclined end and is symmetrically fixedly connected to the guide plate 4 outside the chicken cage 2. The two guide plates 4 together form a guide area, which is nearly Y-shaped. A detection camera 5 is fixedly connected above the outer ends of the two guide plates 4. The detection camera 5 records the state of the eggs as they roll past. A receiving plate is connected to the bottom of the guide plate 4 outside each chicken cage 2, and the receiving plate and the chicken cage 2 are labeled accordingly.
[0027] Specifically, the detection camera 5 can scan and record the number of eggs and the deformation during rolling, thus recording the egg-laying situation.
[0028] The transmission device includes two rotating rollers 6 rotatably connected to the base 1. Each of the two rotating rollers 6 is fitted with a conveyor belt 7. One of the rotating rollers 6 is coaxially fixedly connected to a motor 8 at its outer end. The motor 8 is fixedly connected to the outer wall of the base 1.
[0029] Two positioning plates 9 are symmetrically fixedly connected to the outer wall of the base 1. Rotating rods 10 are rotatably connected to the outer ends of the two positioning plates 9. The two rotating rods 10 are respectively rotatably connected to the collection bags 11 corresponding to the number of chicken cages 2. The collection bags 11 have horizontal holes arranged in an orderly manner to facilitate tearing open the collection bags 11 after collecting the feces.
[0030] The adjustment mechanism includes two sets of vertical sliding grooves 23 symmetrically opened on the outer wall of the base 1. Both sets of vertical sliding grooves 23 are vertically slidably connected to positioning frame plates 14. Two sets of rotating sleeve plates 15 are symmetrically fixedly connected to both sides of the positioning frame plate 14. Both sets of rotating sleeve plates 15 are rotatably connected to pressing rollers 17. The bottom ends of the two pressing rollers 17 can abut against the winding bag 11. The positioning frame plate 14 is located on the outer side of the base 1 and has convex plates 18 symmetrically fixedly connected at both ends. The top of the two sets of convex plates 18 is connected to springs 19. The top of the two sets of springs 19 is fixedly connected to convex plates 22. The two sets of convex plates 22 are respectively fixedly connected to both sides of the outer wall of the base 1. A horizontal groove 20 is opened in the middle of one side of the outer wall of the positioning frame plate 14, and detection cameras 16 are evenly distributed on the top of the positioning frame plate 14.
[0031] Specifically, the pressing roller 17 is an integrated multispectral imaging system (including a 400-1000nm band camera) that can scan the color and shape characteristics of feces every 5 minutes.
[0032] An adjustment slot is provided in the middle of the outer wall of one side of the base 1. The adjustment slot consists of a vertical slot 12 and a limiting slot 13. The vertical slot 12 is located in the middle of the outer wall of the base 1, and a limiting slot 13 is provided on one side of the upper end of the vertical slot 12. An adjustment slider 21 is slidably connected in the adjustment slot. The adjustment slider 21 is also slidably connected to the horizontal slot 20. It is used to guide the entire positioning frame plate 14 to slide along the vertical slot 12 to the limiting slot 13 for limiting, so as to facilitate the cleaning of the roll bag 11 with too much feces attached.
[0033] The implementation principle of the experimental egg-laying hen production performance evaluation device in this application embodiment is as follows:
[0034] After pulling the roll bag 11 below the two clamping rollers 17, first lift the adjusting slider 21 upwards and drive the entire positioning frame plate 14 vertically upwards. After the adjusting slider 21 enters the vertical groove 12 along the limiting groove 13, it will be pushed by the elasticity of the spring 19 to drive the entire positioning frame plate 14 to drive the clamping rollers 17 to abut against the upper part of the roll bag 11. Thus, according to the starting state of the motor 8, the roll bag 11 that has collected chicken manure can be adjusted to avoid the chicken manure from piling up in the same area, which would affect the accuracy of data detection. As the roll bag 11 rotates, when the collection state is full, it will stop rotating. It is necessary to manually contact the clamping rollers 17 to abut against the roll bag 11, and then tear off the collected roll bag 11. After placing the roll bag 11 in place, collection and recording can be carried out again.
[0035] When the laying hen lays eggs, the eggs will be guided down the slope at about 8° along the guide plate 4 and collected through the detection camera 5. As the eggs roll, the detection camera 5 can be used to record the damage and number of the eggs. When there are soft eggs, they may cause blockages, which will require manual cleaning later. Alternatively, the deformation of the soft eggs as they roll along the detection camera 5 can be recorded.
[0036] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
