This method cannot separate and collect feces and urine in time, resulting in high odor concentration in the breeding shed, poor air quality, and poor animal production performance. Even a small number of farms have installed mechanical feces and urine separation devices, which only use conveyor belts to convey mixed feces and urine to the mesh plate, and then use the mesh plate to separate the mixed feces and urine in real time. This separation method easily causes a large amount of feces to be contained in the separated urine, and the feces and urine separation effect is poor.

[0004] Therefore, it is urgent to provide a livestock excrement and urine self-separation device to solve the problem of poor excrement and urine separation effect in the above-mentioned prior art. Summary of the invention

The described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0022] like Figures 1 to 3 As shown, the present invention provides a self-separating device for livestock feces and urine, including a conveying device and a collecting trough 1 arranged at one end of the conveying device; the conveying device is arranged below a breeding shed 5, and the bottom plate of the breeding shed 5 is a slatted plate, and the mesh size of the slatted plate can be designed according to the size of the livestock species and the appearance size of the feces. For large animals (cows), the slats are long strips, and the gap between the slats is wide (3-5cm); for medium-sized animals (pigs, sheep), the gap between the slats is slightly narrower (1.5-2.9cm). The purpose of this design is to ensure that the feces and urine can fall onto the conveying device as automatically as possible without getting the feet of the animals stuck.

[0023] The conveying device includes at least one conveyor belt 2; a feces and urine separation mechanism is arranged on the belt 27 of the conveyor belt 2, a urine guide plate 3 is arranged on the inner side of the belt 27 of the conveyor belt 2, a urine outlet 25 is arranged in the middle of the belt 27, and the urine outlet 25 is arranged corresponding to the urine guide plate 3, urine collecting troughs 4 are arranged on both sides of the conveyor belt 2, and the urine collecting troughs 4 are arranged corresponding to the bottom edge of the urine guide plate 3, and a dewatering pipe 41 is arranged at one end of the urine collecting trough 4.

[0024] When the present invention is in use, feces and urine discharged by livestock such as pigs or cattle raised in the breeding shed 5 fall onto the conveyor belt 2 of the conveying device through the mesh holes on the bottom plate of the breeding shed 5, and the feces and urine are separated by the feces and urine separation mechanism, wherein urine can directly pass through the feces and urine separation mechanism and fall onto the urine guide plate 3, and is guided by the urine guide plate 3 to the urine collecting trough 4 for convergence and is collected through the outlet pipe 41; feces are retained on the belt 27 of the conveyor belt 2, and are transported to the position of the collecting trough 1 by the conveyor belt 2, and the feces on the conveyor belt 2 is made to fall into the collecting trough 1 by the gravity of the feces, thereby completing the separation and collection of feces and urine.

[0025] A further optimized solution is provided to achieve feces and urine separation. The feces and urine separation mechanism includes a separation net 21 arranged on the outside of the belt 27. A support block 1 22 and a support block 23 are installed between the separation net 21 and the belt 27. The support block 23 is symmetrically arranged on both sides of the support block 1 22. A through hole is provided on the support block 1 22, and the through hole is connected to the urine outlet 25 on the belt 27.

[0026] By providing the support block 1 22 and the support block 2 23 , not only the separation net 21 can be kept stable, but also a certain gap can be left between the separation net 21 and the belt 27 to facilitate the discharge of urine.

[0027] To further optimize the solution, in order to facilitate timely discharge of urine and reduce the residence time of urine, thereby ensuring normal discharge of urine, a urinary catheter inclined plate 24 is arranged between the support block 1 22 and the support block 2 23, and one end of the bottom end of the urinary catheter inclined plate 24 is fixedly connected to the support block 1 22, and the urinary catheter inclined plate 24 is arranged correspondingly to the through holes on the support block 1 22.

[0028] A further optimized solution is that when feces falls onto the catheterization inclined plate 24 , in order to reduce the mixing of feces into urine and achieve the feces-urine separation effect again, a diversion microgroove 26 is provided on the catheterization inclined plate 24 , and the diversion microgroove 26 is provided along the inclined direction of the catheterization inclined plate 24 .

[0029] A further optimization scheme is to prevent the feces from falling directly onto the catheter inclined plate 24 under the action of inertia when falling onto the conveyor belt 2. The separation net 21 includes an intercepting mesh plate and a water-permeable layer fixedly connected to the intercepting mesh plate, and the water-permeable layer is arranged on one side of the intercepting mesh plate close to the support block 22.

[0030] According to a further optimization scheme, the water seepage layer is a sponge layer or a water seepage membrane.

[0031] According to a further optimization scheme, in order to facilitate the discharge of urine in the water-permeable layer, one side of the water-permeable layer close to the supporting block 1 22 is an arc-shaped structure or a V-shaped structure.

[0032] According to a further optimization scheme, the materials of the urinary catheter inclined plate 24, the support block 1 22, the support block 2 23, the belt 27 of the conveyor belt 2 and the intercepting mesh plate are all the same.

[0033] As a further optimization scheme, a weight sensor is provided on the separation net 21 of the conveyor belt 2. When the mass of feces and urine on the separation net 21 exceeds a set value, the entire conveying device will automatically start to operate without manual operation.

[0034] Further optimization scheme, the materials used in the livestock feces and urine self-separation device of the present invention are all resistant to feces and urine corrosion, and are divided into two or more sections according to the length of the breeding ground, so that feces and urine will not be too concentrated in a certain section and exceed the maximum load-bearing limit. This can greatly extend the service life, do not need to be replaced for a long time, and reduce the cost of use.

[0035] The livestock excrement and urine self-separation device provided by the present invention has the following working principles:

[0036] The feces and urine discharged by the livestock in the breeding shed 5 fall onto the interception mesh plate through the mesh holes of the breeding shed 5. The interception mesh plate intercepts the solid part of the feces onto the interception mesh plate, and the liquid part passes through the interception mesh plate, seeps through the water seepage layer and falls onto the urinary catheter inclined plate 24. The urinary catheter inclined plate 24 is used to guide the urine to the through hole on the support block 22. The urine enters the urine outlet 25 on the belt 27 through the through hole and falls onto the urinary catheter plate 3 on the inner side of the belt 27. After being guided by the urinary catheter plate 3, it flows into the urine collecting trough 4 and is collected through the outlet pipe 41. The feces are retained on the belt 27 of the conveyor belt 2, and the feces are transported to the collecting trough 1 through the conveyor belt 2, and are collected by the collecting trough 1.

[0037] The present invention can realize the separation and collection of livestock feces and urine. The separation net 21 in the feces and urine separation mechanism adopts a double-layer design, the feces and urine separation effect is good, and the feces content in the separated urine is low.

[0038] The above are only preferred specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
