Description

Technical Field

[0001] The utility model relates to the technical field of animal breeding equipment, in particular to an outlet dry-wet separation excrement cleaning device. Background Art

[0002] A major challenge in raising poultry, cattle, and sheep is dealing with manure. Small animals like chickens and ducks can utilize three-dimensional breeding racks, which not only save space but also utilize the racks' built-in manure handling structures to collect and process their manure. Larger animals like cattle and sheep still require traditional breeding sheds, which are very labor-intensive to collect and process manure from each shed. Furthermore, the manually processed manure requires specialized solid-liquid separation before loading onto trucks, further increasing the workload. Therefore, a device is needed that facilitates the collection and processing of manure and facilitates the separation of dry and wet manure. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an outlet dry-wet separation excrement cleaning device, which can not only facilitate the cleaning of excrement produced by farmed animals in the breeding house, but also facilitate the preliminary dry-wet separation treatment of the excrement, thereby facilitating breeding work.

The conveying surface of the dry-wet separation conveying mechanism is provided with filter holes, and a liquid drainage area is provided below the conveying surface of the dry-wet separation conveying mechanism. Each manure cleaning conveying mechanism conveys mixed manure and urine collected in the breeding house to the dry-wet separation conveying mechanism. Each manure cleaning conveying mechanism collects mixed manure and urine from the breeding house and collects them on the dry-wet separation conveying mechanism. In the process of conveying the mixed manure and urine by the dry-wet separation conveying mechanism, urine and other liquids in the mixed manure and urine leak from the conveying surface of the dry-wet separation conveying mechanism to the liquid drainage area below, thereby realizing the collection, transportation and dry-wet separation of mixed manure and urine in the breeding house.

[0005] As an optional solution, the dry-wet separation conveying mechanism includes a merging section conveyor and an elevating section conveyor. The conveying end of the elevating section conveyor is higher than its conveying head end, and a loading area is provided at the conveying end of the elevating section conveyor. The conveying head end of the elevating section conveyor is connected to the conveying end of the merging section conveyor. The conveying surfaces of the elevating section conveyor and the merging section conveyor are provided with filter holes. Each manure cleaning conveying mechanism conveys the mixed manure and urine collected in the breeding house to the merging section conveyor. The mixed manure and urine collected by the manure cleaning conveying mechanism are first conveyed to the merging section conveyor of the dry-wet separation conveying mechanism, and then conveyed to the elevating section conveyor by the merging section conveyor. The mixed manure and urine are separated into dry and wet forms during the conveying process of the merging section conveyor and the elevating section conveyor. The elevating section conveyor lifts the manure in the mixed manure and urine and transports it to the loading area.

[0006] As an optional solution, the merging section conveyor and the lifting section conveyor are belt conveyors. They share a conveyor belt, with a belt pressing mechanism located above the conveyor belt at the junction of the merging section conveyor and the lifting section conveyor. The conveyor belt is provided with a plurality of filter holes.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0020] See also Figure 1 The outlet dry-wet separation manure cleaning equipment includes a manure cleaning conveying mechanism 1 and a dry-wet separation conveying mechanism 2. The dry-wet separation conveying mechanism 2 and the manure cleaning conveying mechanism 1 are both conveying equipment. The conveying surface of the dry-wet separation conveying mechanism 2 is provided with filter holes. There are multiple filter holes and they are distributed. A liquid drainage area is provided below the conveying surface of the dry-wet separation conveying mechanism 2. When the mixed feces and urine are transported on the dry-wet separation conveying mechanism 2, the liquid part such as urine can pass through the filter holes and fall into the liquid drainage area. The solid part is transported to the designated position by the dry-wet separation conveying mechanism 2. The liquid such as urine flows from the liquid drainage area to the designated position to achieve dry-wet separation. The manure cleaning conveying mechanism 1 is set in the breeding house. The feces, urine, and debris in the breeding house are collected directly or through manual operation on the conveying surface of the manure cleaning conveying mechanism 1. The manure cleaning conveying mechanism 1 transports the mixed feces and urine collected in the breeding house to the dry-wet separation conveying mechanism 2.

[0021] As a preferred embodiment, the dry-wet separation conveying mechanism 2 includes a merging section conveyor 21 and a lifting section conveyor 22. The lifting section conveyor 22 is tilted, and the conveying end of the lifting section conveyor 22 is higher than its conveying head end. A loading area is provided at the conveying end of the lifting section conveyor 22, and the loading area is used for the transport vehicle to stop. The lifting section conveyor 22 can lift the feces and transport it to the transport vehicle in the loading area; the conveying head end of the lifting section conveyor 22 is connected to the conveying end of the merging section conveyor 21, and the merging section conveyor 21 can transport the transported feces to the lifting section conveyor. Conveyor 22, the conveying end of each manure cleaning and conveying mechanism 1 is connected to the merging section conveyor 21, and each manure cleaning and conveying mechanism 1 conveys the mixed manure and urine collected from the breeding house to the merging section conveyor 21. A number of filter holes are distributed on the conveying surface of the merging section conveyor 21 and the conveying surface of the lifting section conveyor 22. In the process of the merging section conveyor 21 conveying the mixed manure and urine to the lifting section conveyor 22 and in the process of the lifting section conveyor 22 conveying the mixed manure and urine to the loading area, the urine in the mixed manure and urine is filtered through the filter holes to reduce the urine content of the manure on the transport vehicle.

[0022] During the process of conveying feces by the merging section conveyor 21 and the lifting section conveyor 22, urine in the mixed feces and urine falls into the liquid drainage area below. The liquid drainage area is provided with a drainage channel or a container to collect or discharge urine.

[0023] The merging section conveyor 21 and the lifting section conveyor 22 are belt conveyors. The merging section conveyor 21 and the lifting section conveyor 22 share a conveyor belt. Specifically, the conveyor belt bypasses the power shafts of the merging section conveyor 21 and the power shafts of the lifting section conveyor 22 at the same time. A number of filter holes are distributed on the conveyor belt. A belt pressing mechanism 23 is provided at the junction of the merging section conveyor 21 and the lifting section conveyor 22 above. The belt pressing mechanism 23 presses the upper belt surface of the conveyor belt at the junction of the merging section conveyor 21 and the lifting section conveyor 22, so that the conveyor belt can be installed and operated at a specified inclination angle at the merging section conveyor 21 and the lifting section conveyor 22. The belt pressing mechanism 23 includes a belt pressing shaft and a belt pressing wheel. The belt pressing shaft is parallel to the rotating shaft of the merging section conveyor 21 and the lifting section conveyor 22. The belt pressing shaft is installed on the frame 3 of the merging section conveyor 21 or the lifting section conveyor 22. The belt pressing shaft is provided with a belt pressing wheel. The belt pressing wheel and the belt pressing shaft are concentrically arranged. The outer end surface of the belt pressing wheel is in contact with the conveyor belt. In the process of the merging section conveyor 21 and the lifting section conveyor 22 driving the conveyor belt to rotate, the belt pressing wheel is driven to rotate by the conveyor belt.

[0024] Of course, the converging section conveyor 21 and the lifting section conveyor 22 can also be independent belt conveyors, with the conveying end of the converging section conveyor 21 above the conveying head of the lifting section conveyor 22, and the mixed feces and urine on the converging section conveyor 21 can be directly transferred to the lifting section conveyor 22.

[0025] Furthermore, to ensure the lifting and conveying effect of the elevating section conveyor 22 on feces, when the merging section conveyor 21 and the elevating section conveyor 22 share a conveyor belt, a number of material-carrying ridges 24 are distributed along the conveying direction of the conveyor belt. The installation position of the material-carrying ridges should be staggered with the belt pressure roller to prevent the belt pressure roller from running over the material-carrying ridges 24. When the merging section conveyor 21 and the elevating section conveyor 22 do not share a conveyor belt, a number of material-carrying ridges 24 are distributed along the conveying direction of the conveying surface of the elevating section conveyor 22. During the process of elevating and conveying feces, if the feces slides down the slope, it will be blocked by the adjacent material-carrying ridges, thus ensuring that the feces can be lifted and transported to the loading area at the elevating section conveyor 22.

[0026] The manure cleaning and conveying mechanism 1 includes a manure cleaning conveyor, which can be a belt conveyor, a chain conveyor, etc. The conveying surface of the manure cleaning conveyor passes through the bottom of multiple breeding houses or the bottom of the manure cleaning outlets of multiple breeding houses. The manure cleaning conveyor is connected to the manure cleaning channels of multiple breeding houses to collect the mixed manure and urine of the multiple breeding houses. There are preferably two or more manure cleaning conveyors, and the conveying ends of each manure cleaning conveyor are connected to the merging section conveyor 21. Multiple manure cleaning conveyors cooperate with the merging section conveyor to collect the mixed manure and urine of multiple breeding houses in an area and aggregate them to the merging section conveyor 21. The merging section conveyor 21 conveys the mixed manure and urine to the lifting section conveyor 22 and the lifting section conveyor 22 transports it to the transport vehicle in the loading area. In the process of transporting the mixed manure and urine by the merging section conveyor 21 and the lifting section conveyor 22, the mixed manure and urine are separated into dry and wet parts, and the urine leaks into the liquid drainage area below and is discharged to the designated position.

[0027] On the basis of the above description, the outlet dry-wet separation excrement cleaning equipment of the present invention further includes a frame 3 , and the excrement cleaning conveying mechanism 1 and the dry-wet separation conveying mechanism 2 are both mounted on the frame 3 .

[0028] As a concrete example, see Figure 1 The wet-dry separation conveying mechanism 2 and each manure removal conveying mechanism 1 each correspond to a corresponding frame 3. Frame 3 is a frame structure with supporting legs. A liquid drainage channel or container is provided below the wet-dry separation conveying mechanism 2 on the frame 3. Using the frame 3 structure in this example, the equipment can be installed on a flat foundation or in an existing manure pit in an existing livestock shed.

[0029] As another specific example, see Figure 2 The frame 3 is provided with a secondary manure chute 31 and a primary manure chute 32. The dry-wet separation conveying mechanism 2 is arranged in the secondary manure chute 31. The secondary manure chute 31 also serves as a liquid drainage channel. The loading area is located at one end of the secondary manure chute 31. The frame 3 is provided with a primary manure chute 32 corresponding to each manure conveying mechanism 1. The primary manure chute 32 communicates with the secondary manure chute 31. Each manure conveying mechanism 1 is installed in a respective primary manure chute 32. The frame 3 can also be the mounting base of the breeding house. The primary manure chute 32 and the secondary manure chute 31 are the old manure pits of the breeding house.

[0030] In order to prevent the mixed feces and urine collected by the manure conveying mechanism 1 from leaking into the primary manure duct 32, a manure guide 33 is provided above the manure conveying mechanism 1 in the primary manure duct 32. The manure guide 33 includes a guide plate. The guide plate is arranged along the conveying direction of the manure conveying mechanism 1. The guide plate is connected to the frame 3 and the lower edge of the guide plate is located above the conveying surface of the manure conveying mechanism 1. The guide plate blocks the gap between the manure conveying mechanism 1 and the inner wall of the primary manure duct 32, thereby preventing the mixed feces and urine in the breeding house from leaking into the primary manure duct 32 through the gap between the manure conveying mechanism 1 and the primary manure duct 32. Preferably, there are two guide plates, one on each side of the manure conveying mechanism 1, and the other on each side of the gap between the manure conveying mechanism 1 and the inner wall of the primary manure duct 32.

[0031] The bottom surface of the primary fecal chute 32 is higher than the bottom surface of the secondary fecal chute 31, so that some mixed feces and urine leaking into the primary fecal chute 32 can flow into the secondary fecal chute 31. The bottom surface of the primary fecal chute 32 can be set as an inclined surface inclined toward the secondary fecal chute 31, and the bottom surface of the secondary fecal chute 31 can be set as an inclined surface inclined in one direction, so as to facilitate the collection and guidance of urine collected by the rack 3 to a designated location.
