DETAILED DESCRIPTION

[0021] 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 described embodiments 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.

[0022] Embodiment 1 See also Figure 1-13The present invention provides a technical solution: a sewage treatment system for livestock and poultry breeding environment, comprising a manure inlet 1 for collecting impurities of livestock and poultry feces, a conveying ditch 2 arranged at one side of the manure inlet 1 and connected to the manure inlet 1, and a desanding pool 3 for desanding manure arranged at a side of the conveying ditch 2 away from the manure inlet 1, and further comprising: The conveying grid 46 is arranged on the conveying groove 2 and the bottom end thereof extends into the interior of the conveying groove 2, and is used to filter hair, weeds and larger impurities and garbage in the feces; A power mechanism, which is arranged on the conveying groove 2 and connected to the conveying grid 46, and is used to drive the conveying grid 46 to rotate; The cleaning unit 48 is disposed at the lower end of the conveying grid 46 and is connected to the power mechanism. It moves along with the power mechanism to clean the impurities remaining in the conveying grid 46 .

[0023] It should be noted that, during operation, the manure produced by livestock and poultry is added to the interior of the manure inlet tank 1, mixed and stirred with the sewage in the field, large manure lumps are broken up and mixed evenly with the sewage, completing the process of accepting and homogenizing the manure raw materials, and then the manure is discharged from the conveying ditch 2 into the primary desanding tank 3 for desanding. In the process of entering the desanding tank 3, the conveying grille 46 can filter the hair, weeds and larger impurities and garbage in the manure. The filtered manure enters the desanding tank 3 for further desanding. The power mechanism on the conveying ditch 2 can drive the conveying grille 46 to circulate inside the conveying ditch 2 to transport impurities to the set position, and in the process of the power mechanism moving, the cleaning unit 48 can clean the conveying grille 46 to reduce the impurities in the manure. The blockage of impurities in the mesh of the conveying grille 46 affects the filtering efficiency of the conveying grille 46 for impurities. By setting the conveying grille 46 on the conveying groove 2, the hair, weeds and larger impurities and garbage in the feces can be effectively filtered, ensuring the smooth transportation of the feces and the smooth subsequent treatment. The cleaning unit 48 is connected to the power mechanism and moves with the power mechanism to automatically clean the impurities remaining in the conveying grille 46, which greatly reduces the workload of manual cleaning and improves the cleaning efficiency. The automatic cleaning function reduces the risk of equipment blockage and damage, extends the service life of the equipment, thereby reducing maintenance costs. Through efficient filtration and automatic cleaning, the present invention can ensure the cleanliness and treatment effect of feces, and provide strong protection for the protection of the livestock and poultry breeding environment and human health.

[0024] In one embodiment, a feed bin 11, a top frame 12 arranged at the upper end of the manure inlet pit 1, a first motor 13 arranged at the upper end of the top frame 12, a rotating shaft 14 arranged at the power output end of the first motor 13, and a mixing blade 15 arranged on the rotating shaft 14 are provided on one side of the manure inlet pit 1, and the mixing blade 15 is arranged inside the manure inlet pit 1.

[0025] This design, see Figure 1-3 The first motor 13 drives the rotating shaft 14 to rotate, thereby driving the mixing blades 15 to stir the inside of the manure inlet tank 1, so that the newly entered feces can be quickly mixed with the liquid in the tank or the existing feces. The stirring action of the mixing blades 15 helps to break up the agglomerate structure of the feces, making it easier for microorganisms to decompose it. By increasing the contact area between the feces and the oxygen in the air or the microorganisms in the tank, the organic decomposition process of the feces can be accelerated and the processing time can be reduced. Continuous stirring can prevent the feces from agglomerating in the manure inlet tank 1 or depositing on the bottom of the tank, thereby maintaining the fluidity and cleanliness of the tank.

[0026] In one embodiment, the power mechanism includes a mounting leg 41 fixed to the upper end of the conveying groove 2, a side plate 42 fixed to the upper end of the mounting leg 41, a second motor 43 fixed to the side plate 42, a conveying shaft 44 arranged at the power output end of the second motor 43 and passing through the side plate 42, and a support roller 45 fixed to the conveying shaft 44, the support roller 45 is located between the two side plates 42, and the conveying grille 46 is sleeved on the support roller 45.

[0027] This design, see Figure 4-6 The second motor 43 drives the support roller 45 to rotate through the conveying shaft 44, thereby driving the conveying grille 46 to move, thereby realizing the continuous conveying of hair, weeds and larger impurities in the feces and sewage, and conveying them to the set area through the impurities. The support roller 45 is fixed on the conveying shaft 44 and is located between the two side plates 42, providing stable support for the conveying grille 46. This design makes the conveying grille 46 not easy to deform or deflect during the conveying process, thereby ensuring the stability and reliability of the conveying.

[0028] In one embodiment, stop bars 461 are fixed at intervals on the outer side of the conveying grid 46 .

[0029] This design, see Figure 4 The stop bars 461 intercept the foreign waste on the conveying grid 46. During the conveying process, the material is confined between the stop bars 461, reducing the possibility of deviation and scattering, thereby ensuring that the foreign waste moves along the predetermined path and position.

[0030] In one embodiment, a blanking plate 47 for collecting impurities is provided at a position of the mounting leg 41 below the second motor 43 , and an adjusting roller 49 for supporting the conveying grid 46 is provided at a position of the side plate 42 below the supporting roller 45 .

[0031] This design, see Figure 7-9The impurities on the conveying grid 46, after being transported to the top of the second motor 43, slide to the unloading plate 47, and then slide from the unloading plate 47 for collection, which can effectively collect these impurities. The adjusting roller 49 is located below the supporting roller 45, providing additional support for the conveying grid 46, so that an installation space is formed below the conveying grid 46, providing an installation space for the cleaning unit 48.

[0032] In one embodiment, a guide block 421 is fixed to the lower end of the side plate 42, and the cleaning unit 48 includes a rotating disk 481 fixed on the conveying shaft 44, a first wedge block 482 fixed on the rotating disk 481, a cleaning rod 484 passed through the guide block 421, and a second wedge block 483 fixed to the side of the cleaning rod 484 close to the first wedge block 482 and cooperating with the first wedge block 482, and the side of the cleaning rod 484 away from the first wedge block 482 is passed through the guide block 421.

[0033] This design, see Figure 6 ,as well as Fig.10 When the conveying shaft 44 rotates, the rotating disk 481 rotates accordingly. Since the first wedge block 482 is fixed on the rotating disk 481, it will also rotate with the rotating disk 481. The rotational movement of the first wedge block 482 will interact with the second wedge block 483. Since the second wedge block 483 is fixed on the cleaning rod 484, this interaction will be converted into the reciprocating motion of the cleaning rod 484. The reciprocating motion of the cleaning rod 484 enables it to regularly clean the impurities and residues in the conveying grid 46 or the surrounding area, thereby realizing the function of automatic cleaning and reducing the frequency and labor intensity of manual cleaning. The guide block 421 is fixed at the lower end of the side plate 42, providing stable guidance and support for the cleaning rod 484, which ensures that the cleaning rod 484 can maintain a stable trajectory during the reciprocating motion, thereby improving the accuracy and efficiency of cleaning.

[0034] In one embodiment, an extrusion plate 485 is fixed on the cleaning rod 484, and a mounting groove 42101 for the extrusion plate 485 to move is opened on the guide block 421. An elastic member 486 connected to the extrusion plate 485 is arranged inside the mounting groove 42101, and the elastic member 486 is made of a damped spring or elastic pad.

[0035] This design, see Figure 8 The extrusion plate 485 moves in the mounting groove 42101 with the reciprocating motion of the cleaning rod 484, and produces a continuous extrusion and scraping effect on the conveying grille 46 or the surrounding area. This extrusion and scraping effect helps to more thoroughly remove impurities and residues and improve the cleaning effect. The elastic member 486 provides a continuous elastic force to the extrusion plate 485, so that the extrusion plate 485 always maintains contact with the conveying grille 46 or the cleaning surface.

[0036] In one embodiment, an extension rod 4841 is fixed to one side of the cleaning rod 484, a fixed rod 4842 is fixed to the side of the extension rod 4841 away from the cleaning rod 484, cleaning brushes 4843 are provided at the lower ends of the extension rod 4841 and the fixed rod 4842, the cleaning brush 4843 extends into the mesh of the conveying grid 46, and the extension rod 4841 is located above the adjusting roller 49.

[0037] This design, see Figure 8 ,as well as Fig. 9 The cleaning brush 4843 extends into the mesh of the conveying grille 46, and can directly contact the impurities and residues inside the mesh for deep cleaning. This design ensures that each mesh of the conveying grille 46 can be thoroughly cleaned, thereby improving the thoroughness and efficiency of cleaning. By arranging the extension rod 4841 and the fixed rod 4842, the cleaning range of the cleaning brush 4843 is expanded. The design of the extension rod 4841 and the fixed rod 4842 enables the cleaning brush 4843 to cover a wider area of ​​the conveying grille 46, including those corners and edges that are difficult to reach directly. The cleaning brush 4843 produces a continuous brushing effect on the mesh of the conveying grille 46 during the reciprocating motion of the cleaning rod 484.

[0038] Embodiment 2 In one embodiment, a knocking piece 4844 for knocking the conveying grille 46 is provided on the side plate 42, and the knocking piece 4844 includes a fixing plate 48443 fixed on the fixing rod 4842, a rack 48444 fixed on the fixing plate 48443 away from the fixing rod 4842, a mounting plate 48441 fixed between the two side plates 42, a connecting shaft 48442 fixed at the lower end of the mounting plate 48441, a gear 48445 sleeved on the connecting shaft 48442, and a knocking block 48446 fixed on the gear 48445 away from the rack 48444, the gear 48445 is meshingly connected with the rack 48444, and the knocking piece 48444 is inclined toward the side close to the conveying grille 46.

[0039] This design, see Figure 8-13 The reciprocating motion of the cleaning rod 484 drives the rack 48444 to move, which in turn drives the gear 48445 to rotate, driving the knocking block 48446 to knock on the conveying grille 46. This knocking action can vibrate the conveying grille 46, so that the stubborn impurities and residues attached to the grille are loosened and fall off, thereby enhancing the cleaning effect. The inclined setting of the knocking piece 4844 makes the knocking force more evenly distributed on the conveying grille 46. This design makes the knocking action and the reciprocating motion of the cleaning rod 484 synchronous, realizes the automation of the cleaning process, and no additional manual operation is required.

[0040] In one embodiment, a water spray pipe 5 is provided at a position of the conveying ditch 2 above the conveying grid 46 .

[0041] This design, see Figure 1 The water spray pipe 5 can spray water onto the conveying grille 46 , and the water flow can directly wash away the impurities and residues on the grille, greatly improving the cleaning efficiency and ensuring the thoroughness of the cleaning of the conveying grille 46 .

[0042] In addition, if there are descriptions involving "first", "second", etc. in the embodiments, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their importance relative to the specification or implicitly indicating the number of the indicated technical features.
