Description

Technical Field

[0001] The utility model relates to the technical field of poultry breeding equipment, in particular to a free-range laying hen laying box for reducing dirty and broken eggs. Background Art

[0002] With the development of the concept of animal welfare and science, the non-cage farming mode has grown rapidly in countries and regions around the world that attach importance to animal welfare. The production efficiency, egg production quality and welfare treatment of laying hens have also been improved accordingly, making more and more people full of confidence in the non-cage production method.

[0003] However, for a long time, people in our country have favored free-range eggs. Even regardless of the dirt on the eggshell surface and the short shelf life, by studying the egg-laying behavior preferences of free-range chickens, we have learned that hens like to gather in darker corners to lay eggs, resulting in many laying boxes being idle. At the same time, there are problems such as many dirty and broken eggs and inability to automatically collect eggs in the existing free-range mode. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a free-range laying hen laying box for reducing dirty and broken eggs, which is characterized by being wide, having a three-color light-shielding nest curtain, being fecal leakage-proof, having automatic egg rolling, having a foot-wiping inclined plate, a straw rope and a buffer pad. The wide laying box can accommodate more hens to lay eggs together without being squeezed, reducing the occurrence probability of broken eggs; the three-color covering nest curtain can attract hens to be willing to lay eggs, reducing out-of-nest eggs, and can also help hens remember the egg-laying position and avoid gathering to lay eggs; the fecal leakage-proof laying nest is cleaner and more hygienic. After the eggs are produced, they immediately roll into the egg collection trough, further reducing the breakage and dirt of the eggs, maximizing the utilization rate of the laying box and extending the shelf life of the eggs; the foot-wiping inclined plate can reduce the sediment on the chicken feet and is beneficial to keeping the egg box clean; the setting of the straw rope can reduce the rolling distance of the eggs, and the buffer pad can shock-absorb, further reducing the breakage rate of the eggs.

[0005] The technical solution adopted by the utility model to solve its technical problem is:

[0006] A free-range laying hen laying box for reducing dirty and broken eggs, including an egg box body. The top of the egg box body is provided with a top plate, the two sides are provided with side plates, the back is provided with a back panel, the front is provided with an opening, and the bottom is provided with a bottom net; the bottom net inclines towards the opening and extends out with an egg collection trough; the end of the egg collection trough is rolled up upwards to prevent eggs from rolling down, and the end of the egg collection trough is also connected to the upper end of an inclined plate; the lower end of the inclined plate touches the ground; a plurality of nest curtains are evenly arranged at the upper end of the opening, and the lower end is connected with an egg shielding plate connected to the egg collection trough.

[0007] There is straw rope provided on the back panel. The bottom net is a net-shaped feces leakage structure with the front end lower and the rear end higher. The front end of the bottom net is connected to the egg collection trough, and the end of the egg collection trough is rolled up 5 - 8 cm upwards. The bottom net is inclined 8 - 9° along the opening direction and has a width of 10 - 15 cm.

[0008] The four corners at the bottom end of the egg box body are connected to the top ends of four columns, and the bottom ends of the columns are placed on the ground. The bottom net is more than 10 cm above the ground.

[0009] The other end of the inclined plate is placed on the ground. The inclined plate is a net-shaped structure and has an inclination of 30 - 40°.

[0010] Multiple nest curtains leave gaps with a width of 2 cm every 30 - 50 cm. The nest curtains are in an inverted trapezoid structure.

[0011] The beneficial effects of the present utility model are as follows:

[0012] 1. By adding nest curtains that block light in three colors, red, yellow, and green, which chickens like, to the large egg-laying box, the attractiveness of the egg-laying box is increased, the light in the egg-laying box is weakened, and different arrangements and combinations of these three colors (it can be a whole piece of one color or a combination of 2 - 3 colors) are used to enable hens to distinguish and fix the egg-laying positions. This not only satisfies the habit of hens to lay eggs adjacent to each other and in groups, but also improves the situation where hens are squeezed and injured in a narrow egg box, thereby maximizing the utilization rate of the egg-laying box, preventing the egg-laying box from being idle, and at the same time improving the safety and comfort of the hens' egg-laying environment. The eggs produced are automatically rolled into the egg collection trough through the bottom net of the egg-laying box for collection.

[0013] 2. Through the bottom net inclined at 8 - 9°, the eggs produced can immediately roll from the bottom net into the egg collection trough, reducing the probability of eggs being soiled by feces and avoiding the situation where eggs are repeatedly incubated by hens, thereby extending the shelf life of eggs.

[0014] 3. A plastic leakage net with a buffering function is laid on the bottom net, reducing the breakage of eggs and avoiding the deposition of chicken feces, egg liquid, and soil in the egg box, thereby eliminating the hidden danger of the breeding and spread of parasites and at the same time improving the hens' egg-laying environment.

[0019] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] As Figures 1 to 3 shown, a free-range laying hen egg production box for reducing dirty and broken eggs includes an egg box body. The top of the egg box body is provided with a top plate 1, the two sides are provided with side plates 2, the back is provided with a back panel 8, the front is provided with an opening 3, and the bottom is provided with a bottom net 11; the bottom net 11 is inclined towards the opening 3 and extends out with an egg collection trough 5; the end of the egg collection trough 5 is rolled up upwards to prevent eggs from rolling down, and the end of the egg collection trough is also connected to the upper end of an inclined plate 4; the lower end of the inclined plate 4 touches the ground; a plurality of nest curtains 6 are evenly arranged at the upper end of the opening 3, and the lower end is connected to an egg shielding plate 7 connected to the egg collection trough 5.

[0021] A straw rope 9 is arranged on the back panel 8. The bottom net 11 is a net-shaped manure leakage structure with the front end lower and the rear end higher. The front end of the bottom net 11 is connected to the egg collection trough 5. The end of the egg collection trough 5 is rolled up upwards by 5 - 8 cm. The bottom net 11 is inclined by 8 - 9° along the direction of the opening 3 and has a width of 10 - 15 cm.

[0022] The four corners of the bottom end of the egg box body are connected to the tops of four columns 10. The bottoms of the columns 10 are placed on the ground, and the bottom net 11 is more than 10 cm away from the ground.

[0023] The other end of the inclined plate 4 is placed on the ground. The inclined plate 4 is a net-shaped structure and has an inclination of 30 - 40°.

[0024] A 2 - cm - wide gap is left every 30 - 50 cm between a plurality of the nest curtains 6. The nest curtains 6 are in an inverted trapezoid structure, which is beneficial to the passage of chickens.

[0025] The top plate 1 is in an inclined state to prevent hens from perching at night and reduce surface pollution at the same time.

[0026] By adding a nest curtain 6 that blocks light in red, yellow, and green, which chickens like, to the spacious egg-laying box, the attractiveness of the egg-laying box is increased, the light inside the egg-laying box is weakened, and different permutations and combinations of these three colors (it can be a whole piece of one color, or a combination of 2-3 colors) are used to enable hens to distinguish and fix their egg-laying positions. This not only satisfies the hens' habit of laying eggs adjacent to each other and clustering, but also improves the situation where hens are squeezed and injured in narrow egg boxes. Thus, the utilization rate of the egg-laying box is maximized, the egg-laying box will not be idle, and at the same time, the safety and comfort of the hens' egg-laying environment are improved. The eggs produced are automatically rolled into the egg collection trough 5 through the bottom net 10 of the egg-laying box for collection.

[0027] Baffles are provided on both sides of the egg collection trough 5, preferably in a triangular shape, which can block the eggs.

[0028] Through the bottom net 11 inclined at 8-9°, the eggs produced immediately roll from the bottom net 11 into the egg collection trough 5, reducing the probability of eggs being soiled by feces and avoiding the situation where eggs are repeatedly incubated by hens, thereby extending the shelf life of the eggs.

[0029] A plurality of hinge leaves are provided on the opening 3, and the egg shielding plate 7 is connected to the egg collection trough 5 through hinges. The lower end of the egg shielding plate 7 opens and closes up and down through the hinge leaves, facilitating the picking up of eggs in the egg box.

[0030] A plastic leakage net with a buffering function is laid on the bottom net 11, reducing the breakage of eggs and avoiding the deposition of chicken manure, egg liquid, and soil in the egg box, thereby eliminating the hidden danger of the breeding and spread of parasites and at the same time improving the hens' egg-laying environment.

[0031] The distance between the two sides of the egg-laying box can be widened as much as possible. On the premise of ensuring the bearing capacity and structural stability of the egg-laying box, the use of the side plate 2 is minimized as much as possible. This design can not only reduce the material cost of the egg box, but also provide more free space for hens. It can not only satisfy the hens' habit of clustering to lay eggs, enabling them to accompany each other when laying eggs and increasing their sense of security, but also prevent them from being squeezed and injured when clustering in a narrow egg-laying nest, and at the same time reduce the probability of egg breakage and soiling.

[0032] The egg collection trough 5 and the bottom net 11 of the egg-laying box adopt a design of a manure-draining net away from the ground, avoiding the deposition of chicken manure, egg liquid, and soil, thereby eliminating the hidden danger of the breeding and spread of parasites and also facilitating the cleaning of the area below the egg box. At the same time, the egg collection trough 5 is inclined forward at 8-9°, the front end of the egg collection trough 5 is rolled up 5-8 cm upward, and the egg shielding plate 7 can not only protect the eggs from being pecked, but also serve as a pedal for hens to enter the egg-laying box.

[0033] At the entrance of the laying box, there are three light-blocking nest curtains 6 in red, yellow, and green that can attract hens. Through different permutations and combinations (such as red - yellow - green - yellow - red - green - red - yellow - green - yellow - red - green, or 2 - 3 color patches on each piece), while blocking light, they can also serve as road signs, aiming to help hens remember their respective laying positions and avoid the occurrence of concentrated laying.

[0034] Some straw-like materials are fixed on the back panel 8 of the laying box (opposite to the position of the entrance of the laying box). This can attract the hens' heads towards the straw, reduce the possibility of being disturbed by other chickens during the laying process of hens, and can also shorten the distance from the cloaca of the hens to the egg collection trough 12, reducing the rolling distance of eggs after laying and the breakage rate of eggs.

[0035] The laying boxes are usually placed closely against the wall of the chicken coop. The number of egg boxes is increased or decreased according to the laying rate and usage of the laying hens, so as to match the number of laying hens.

[0036] The back panel 8 of the laying box adopts a snap-on and easily detachable grille-type metal plate, on which straw-like materials can be woven and fixed. This can attract hens to turn their heads towards the back panel, shorten the distance for eggs to roll into the egg collection trough after laying, and is also convenient for maintenance.

[0037] The light-blocking nest curtain 6 selects opaque flexible plastic vertical pieces, leaving gaps of about 2 cm every 30 - 50 cm, and adopting an inverted trapezoidal structure, which is convenient for hens to check and enter and exit.

[0038] The laying box only needs to be designed with one layer and does not need to be designed with multiple layers, because hens always choose higher positions to lay eggs, resulting in the lower egg nests being idle.

[0039] Before the laying hens start laying eggs, the egg boxes are evenly placed in the chicken coop. The colored nest curtain 6 at the entrance of the laying box will attract the attention of the hens. Hens have an innate preference for red. When the hens approach the egg box, the opening design in the middle of the nest curtain 6 allows the hens to check the egg box. When the hens check the egg box, they will find that there are straw ropes 9 or straw mats on the back panel 8. Since hens have an innate preference for straw, they will enter the egg box to pick up straw. Since the straw and the straw mat are both behind the egg box, the cloaca of the hens will naturally face the nest curtain 6 when laying eggs, reducing the distance for eggs to roll into the egg collection trough 5 after laying, and can reduce the breakage of eggs; and the tail end of the egg collection trough 5 is rolled up 5 - 8 cm upwards, which can prevent eggs from rolling to the ground, and a layer of buffer net can be laid on the bottom net 11 to play a shock-absorbing role, which can further reduce the breakage rate of eggs.

[0040] To ensure the air quality inside the egg box, the rear panel 8 can be made of a grille and covered with a sunshade net on the outside, which not only ensures a relatively dark egg-laying environment inside the box but also ensures air circulation inside the box. In addition, straw ropes 9 that hens like most are evenly tied to the rear panel 8. This design can effectively attract the hens' heads towards the back panel, making the position where the eggs are laid closer to the egg collecting trough, reducing the rolling distance of the eggs, and lowering the egg breakage rate.

[0041] The net-like inclined plate 4 is hung above the opening 3 and connected to the ground below, with an angle of 30 - 40 degrees. This is not only conducive to the chickens entering the egg-laying box but also helps to wipe off the sediment on the chickens' feet, keeping the egg-laying box clean and hygienic.

[0042] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
