Description

Technical Field

[0001] The utility model relates to the technical field of ecological laying hen breeding, in particular to an in-situ treatment device for laying hen breeding excrement. Background Art

[0002] Chickens have a short digestive tract and a low absorption conversion rate. They can only absorb 60-70% of nutrients, and about 30-40% of nutrients are excreted from the body; therefore, poultry manure contains a large amount of unabsorbed nutrients, including 89.8% dry matter, 28.8% crude protein, 12.7% crude fiber, 14.4% digestible protein, 2.6% phosphorus, and 8.7% calcium. These chicken manures are rich in nutrients and have a strong odor. If they are not treated in time, the nutrients will migrate to the environment, causing serious environmental pollution and wasting available resources. At present, most of the manure treatment for laying hens is composting. This technology takes a long time to process, requires certain manure cleaning facilities, is costly, and puts great pressure on the environmental protection of small and medium-sized farms.

[0003] Using black soldier flies to feed on livestock and poultry manure is a manure treatment technology with low treatment costs and good environmental benefits. Black soldier flies are insects of the genus Soldierfly of the family Smilocidae in the order Diptera. Black soldier flies go through the stages of eggs, larvae, prepupae, pupae and adults in their life cycle. They can feed on organic waste and produce high-quality organic fertilizer and high-value animal protein. Because of their rapid reproduction, large biomass, wide range of food, high absorption and conversion rate, low feeding cost, and good animal palatability, they are used to treat livestock and poultry manure and make use of it as a resource. Using soldier fly larvae to treat livestock and poultry manure can not only effectively reduce manure accumulation and prevent mosquitoes and flies, but also obtain organic fertilizer and insect protein, which has good environmental and economic benefits.

[0004] Therefore, using black soldier flies to treat laying hen manure in situ is of great significance for solving the problem of chicken manure pollution in small and medium-sized laying hen farms. Utility Model Content

[0031] like Figure 1-Figure 3 As shown, an in-situ treatment device for laying hen manure disclosed in the utility model comprises:

[0032] A black soldier fly transformation pool 1, wherein the black soldier fly transformation pool 1 is a groove structure arranged downward from the ground, wherein a pair of opposite side surfaces of the groove structure are arranged to penetrate outward;

[0033] A laying hen breeding cage 2, wherein the laying hen breeding cage 2 is arranged above the ground, and the laying hen breeding cage 2 is placed above the black soldier fly transformation pool 1;

[0034] A feces conveying mechanism 3, wherein the feces conveying mechanism 3 is arranged in the black soldier fly conversion pool 1, and the conveying device conveys feces along the through direction of the black soldier fly conversion pool 1;

[0035] The manure pushing mechanism 4 is arranged on both sides of the laying hen breeding cage 2 and is used to push the manure dropped on the ground by the laying hen breeding cage 2 into the black soldier fly conversion pool 1.

[0036] The above-mentioned black soldier fly conversion pool 1 is dug downwards on the ground, with three sides constructed of cement, a U-shaped groove at the bottom, and openings at the top and one pair of opposite sides. The bottom and another pair of opposite sides are set as cement walls, the opening at the top serves as an entrance for feces, and the openings on the side walls serve as a conveying port for the converted insect feces.

[0037] In some embodiments, the laying hen breeding cage 2 includes a support 22 and a cage body 21, the support 22 is arranged on the ground in a herringbone shape, the cage body 21 is fixedly connected to the support 22, and the cage body 21 is distributed on the support 22 in a stepped manner.

[0038] The bracket 22 is installed on the ground, the base 5 is fixed on the ground, and then the bracket 22 is installed on the base 5. Two bases 5 are provided, which are respectively located on both sides of the black soldier fly transformation pool 1. The brackets 22 on the two bases 5 are inclined, and the inclination direction is toward the black soldier fly transformation pool 1, forming a herringbone structure;

[0039] The cages 21 are arranged on the bracket 22 along the inclination direction of the bracket 22 in a stepped distribution, and two adjacent cages 21 on each bracket 22 do not overlap in the vertical direction, so that feces in the upper cage 21 will not fall into the lower cage 21;

[0040] In order to ensure that feces fall off, the bottom of the cage body 21 needs to be set as a hollow structure, and the hollow structure does not affect the standing and walking of the laying hen.

[0041] The specific installation method between the cage body 21 and the bracket 22 can be welding to fix the cage body 21 on the bracket 22; or bolts or other assembly methods can be used to detachably install the cage body 21 on the bracket 22.

[0042] The projections of two adjacent cage bodies 21 on the horizontal plane do not overlap with each other.

[0043] Furthermore, a three-layer cage body 21 is fixed on both sides of the bracket 22, and a feed trough and a nipple drinker are arranged in the cage body 21.

[0044] In some embodiments, the feces transport mechanism 3 includes a U-shaped spiral conveying trough 31, and the U-shaped spiral conveying trough 31 is fixedly connected to the bottom of the black soldier fly conversion pool 1, and a screw conveyor 32 is arranged inside the U-shaped spiral conveying trough.

[0045] The above-mentioned U-shaped spiral conveying trough 31 is used as a place for the transformation of black soldier flies. There are two of them, which are close to the two side walls of the black soldier fly transformation pool 1. They can receive the feces pushed by the feces pushing mechanisms 4 on both sides and transform them in the U-shaped spiral conveying trough 31. After the transformation is completed, the insect feces are transported away for treatment through a bolt conveyor.

[0046] Furthermore, the manure pushing mechanism 4 includes a bottom plate 41 and a pushing plate 47, the bottom plate 41 is fixed to the ground, and at least one group of manure pushing components is arranged on one side of the bottom plate 41 close to the black soldier fly conversion tank 1;

[0049] In another embodiment, a spring 6 may be provided between the push plate 47 and the bottom plate 41 . The spring 6 extends during the process of the push plate 47 pushing feces, and the spring 6 cooperates with the push plate 47 to retract during the recovery process.

[0050] Furthermore, the push plate 47 is provided with a shovel-shaped arc surface on one side close to the black soldier fly conversion tank 1 .

[0051] A shovel-shaped structure is provided on one side of the push plate 47 close to the black soldier fly conversion tank 1 to facilitate the cleaning of feces. At the same time, in order to prevent the feces from falling on the other side of the push plate 47 (close to the bottom plate 41), the push plate 47 needs to be retracted to a position close to the bottom plate 41 after each feces cleaning;

[0052] At the same time, the push plate 47 is set at a certain height to prevent excessive feces from piling up above the height of the push plate 47 during each feces cleaning process, and then falling on the other side of the push plate 47. The above problem can also be solved by regularly cleaning the feces to ensure that the amount of feces each time is within the cleaning range of the push plate 47.

[0053] Specifically, the implementation principle of the utility model is:

[0054] Mix 5-day-old black soldier fly larvae with feed and put them into the conversion tank. The amount of larvae to be put in is determined according to the size of the conversion tank. After the larvae are put in, some larvae can eat feed and spread it to a thickness of 8cm-10cm. The humidity of the black soldier fly filler is controlled at 70%-80%;

[0055] After the black soldier fly larvae are put into the conversion tank, the laying hens are put into the cage 21. During the breeding process, part of the feces falls into the conversion tank, and part falls on the feces receiving plate. The feces pushing device is started regularly every day to push the feces on the feces receiving plate into the conversion tank, and the black soldier fly larvae convert the feces;

[0056] Observe the larvae. When some larvae turn black, start the excrement collection device to remove the larvae and materials, and then add the mixed larvae and feed again;

[0057] The cleared insect bodies and insect feces are used separately: after the insect feces are separated, the insect bodies can be dried and ground into powder and used as protein feed, or can be directly fed to fish, shrimp, livestock and poultry; the insect feces can be used as organic fertilizer after being dried in the sun.

[0058] The above specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0059] The technical features of the above embodiments may be arbitrarily combined (as long as there is no contradiction in the combination of these technical features). To make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.

[0060] The above is a relatively specific and detailed description of the utility model through general description and specific embodiments.
