DETAILED DESCRIPTION

[0023] Reference to an embodiment herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0024] The utility model is described in detail below in conjunction with the accompanying drawings.

[0025] like Figure 1-2 As shown, a manure treatment device for livestock and poultry breeding includes a tank body 1, which is arranged on a mobile frame 11. The mobile frame 11 includes a frame and casters arranged at the bottom of the frame. The top wall of the tank body 1 is provided with a manure feed port 12, and the bottom wall is provided with a discharge port 13. The manure includes waste consisting of feces and urine generated in the process of livestock and poultry breeding and production flushing sewage. After the manure enters the device, the filter plate 2 arranged in the tank body 1 performs preliminary filtration of the manure to remove large particles of manure residue therein. The built-in crushing knife 6 is used to crush the filtered large particles of manure residue to refine the incompletely dissolved manure particles. Then the refined manure residue enters the stirring and mixing area, is stirred and fused with the manure to make it evenly mixed, and finally discharged through the discharge port 13. The specific structure is as follows:

[0026] A horizontally arranged filter plate 2 and a vertically arranged vertical shaft 4 are provided in the tank body 1, wherein the filter plate 2 divides the internal space of the tank body 1 into an upper and a lower half area, the upper half area is used for crushing fecal residue, and the lower half area is used for mixing and dissolving, the vertical shaft 4 coincides with the central axis of the tank body 1, the upper end of the vertical shaft 4 extends upward out of the top wall of the tank body 1 and is transmission-connected to the driving mechanism 8, the vertical shaft 4 is rotationally matched with the top wall, the bottom wall and the filter plate 2 of the tank body 1, the part of the vertical shaft 4 located in the upper half of the tank body 1 is provided with a crushing knife 6, the outside of the crushing knife 6 is provided with a barrel-shaped cover 3, the upper part of the barrel-shaped cover 3 is open and connected to the feed port 12, the incoming fecal water enters the area formed by the barrel-shaped cover 3 and the filter plate 2, the upper edge of the barrel-shaped cover 3 is fixedly connected to the top wall of the tank body 1, the lower edge of the barrel-shaped cover 3 is close to the filter plate 2, and the side wall of the barrel-shaped cover 3 is evenly provided with filter residue holes, wherein the filter residue holes are preferably long strip holes.

[0027] Specific reference Figure 4 The driving mechanism 8 is a servo motor, which is arranged on the outside of the top wall of the tank body. The output shaft of the servo motor and the upward extending end of the vertical shaft 4 are respectively provided with fan gears 81, and the two fan gears are meshed with each other. Of course, other driving methods can also be used, such as a driving structure of a motor and a pulley.

[0028] The servo motor drives the vertical shaft 4 to rotate and drives the crushing knife 6 to crush the feces. After the feces water is filtered through the filter plate 2, large particles of feces are left in the area formed by the barrel cover 3 and the filter plate 2. The crushing knife 6 crushes them. As the crushing knife 6 rotates, the feces are also driven to rotate. The feces contact the barrel cover 3 through centrifugal action. When the particle size meets the requirements, it will pass through the filter hole and the filter plate into the lower half of the tank body 1.

[0029] The part of the vertical axis 4 located in the lower half of the tank body 1 is provided with a stirring member 5, and the stirring member 5 is a spiral structure. Figure 2 When the vertical shaft 4 rotates, the stirring member 5 is driven to rotate synchronously. In addition, when the stirring member 5 with a spiral structure rotates, the manure water at the bottom of the tank body 1 can be transferred upward to form a circulating stirring effect. The manure water mixture entering the lower half of the tank body 1 is fully mixed and stirred by the stirring member 5, so that the manure residue can be fully dissolved in the manure water to achieve the purpose of full mixing. Finally, the treated manure water is discharged through the discharge port 13.

[0030] like Figure 3As shown, it is particularly important to explain that the filter plate 2 can be set to be movable. Specifically, a limiting portion 21 is circumferentially arranged on the inner wall of the tank body 1, one side of the limiting portion 21 is fixedly arranged on the inner wall of the tank body 1, and a slot is opened on the opposite side. The edge of the filter plate 2 is embedded in the slot, and the width of the slot in the vertical direction is greater than the thickness of the filter plate 2. The filter plate 2 can move in the slot. In addition, a plurality of springs 22 are respectively arranged on the upper and lower sides of the filter plate 2 located in the slot, one end of the spring 22 is abutted against the lower surface of the filter plate 2, and the other end of the spring 22 is fixedly arranged on the inner wall of the slot. The purpose of the filter plate 2 being movable is that when the filter residue is removed from the barrel When the shaped cover 3 is thrown out and falls on the filter plate 2, it can pass through the filter hole smoothly through the movement of the filter plate 2. In practice, the effect of achieving this purpose by relying on the vibration of the device itself is not obvious. For this reason, a vibrating member 9 is also provided. The vibrating member 9 is a vibrating structure, which includes a circular plate 91 arranged on the vertical axis 4. The diameter of the circular plate 91 is small, slightly larger than the diameter of the vertical axis 4. The circular plate 91 and the filter plate 2 are respectively provided with circumferentially uniformly distributed protrusions 92 on the side opposite to the surface. When the circular plate 91 rotates with the vertical axis 4, the protrusions 92 thereon collide with the protrusions 92 on the filter plate 2, so that the filter plate 2 produces a shaking effect.

[0031] In addition, the vibration element 9 may also be a vibration motor, etc. It should be noted that the vibration motor needs to be sealed at the inlet and outlet to avoid short circuit.

[0032] like Figure 2 and Figure 4 As shown, it is particularly important to explain that it also includes a cleaning component 7, which includes a connecting arm 71 arranged on the vertical shaft 4 near one end of the crushing knife 6, and a scraper 72 is provided at the end of the connecting arm 71, and the scraper 72 is close to the inner wall of the barrel cover 3, wherein the scraper is a brush or a stainless steel plate. The cleaning component 7 rotates synchronously with the vertical shaft 4, and the cleaning component 7 can clean the feces residue adhering to the inner wall of the barrel cover 3 to prevent it from drying and hardening, blocking the filter residue holes, and thus affecting the crushing effect.

[0033] like Figure 5 As shown, the inner wall of the upper half of the tank body 1 is provided with several diversion channels 10 along the circumferential direction. By providing the diversion channels 10, part of the manure water thrown to the side wall of the tank body 1 during crushing can be quickly gathered and flow to the lower half of the tank body 1 by its own weight. It should be noted that the surface of the diversion channel 10 is polished, and its surface roughness is small and it is not easy to adhere.

[0034] The advantages of the utility model are that through the processing steps of filtering, crushing, stirring and fusing, the feces sprayed on the surface of the filler are ensured to be uniform, thereby improving the fermentation efficiency and stability of the microbial nest; at the same time, the device has a simple structure, is easy to operate and maintain, and is suitable for livestock and poultry farms of various sizes.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.

[0036] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
