[0004] The deficiency of the prior art in cleaning livestock manure in farms is that the prior art generally uses sweeping or suctioning to collect livestock manure in farms, or directly uses a high-pressure water gun to flush the manure. However, the amount of manure produced by livestock is large. When collecting manure by sweeping or suctioning, it is difficult for the existing cleaning mechanism to clean the accumulated manure and it is difficult for the existing cleaning mechanism to fully clean the manure. Since the manure suction head of the existing manure suction mechanism cannot adapt to the change of the amount of manure, it is easy to cause the manure suction mechanism to be blocked when sucking manure. Using a high-pressure water gun to directly flush the manure will inevitably waste a lot of water resources. Summary of the invention

DETAILED DESCRIPTION

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-7 As shown, a sewage suction mechanism provided by an embodiment of the present invention includes a sewage collecting bucket 1 and a sewage suction pump 2 installed on the sewage collecting bucket 1, wherein the sewage suction pump 2 is connected to one end of a pipe 3, and a sewage suction component 4 is provided at the other end of the pipe 3, and a pressure regulating mechanism 5 is provided on the sewage suction component 4, and the pressure regulating mechanism 5 is used to adjust the sewage suction pressure of the sewage suction component 4.

[0031] Specifically, after the livestock in the farm produce feces, the staff turns on the switch of the feces suction pump 2, so that the feces suction pump 2 starts to suck the feces, and the feces passes through the sewage suction component 4, the pipeline 3 and the feces suction pump 2 in turn and enters the feces collecting bucket 1 for collection. In the process of collecting feces, the opening size of the sewage suction component 4 itself is adjusted by the pressure regulating mechanism 5, so that the opening of the sewage suction component 4 can be adaptively changed in size to achieve the adjustment of the sewage suction pressure, ensuring that the sewage suction mechanism can fully collect feces, speed up the cleaning speed of feces, and avoid blockage. The sewage suction mechanism is moved by the staff so that the sewage suction mechanism can collect feces on the ground.

[0032] A sewage suction mechanism provided in an embodiment of the present invention can adjust the sewage suction pressure of the sewage suction component 4 through the pressure adjustment mechanism 5 according to the amount of feces sucked in real time by the feces suction pump 2, so that the opening of the sewage suction component 4 itself can be adaptively changed, thereby ensuring that the sewage suction mechanism can fully collect feces, speed up the cleaning speed of feces, avoid blockage, reduce the situation where feces sticks to the ground, and ensure the cleaning effect.

[0033] In another embodiment provided by the present invention, the sewage suction component 4 includes a sewage suction head 41, which is arranged at the end of the pipe 3, and the sewage suction head 41 is a rectangular cylinder or a cylinder approximately in a rectangular shape so that its bottom surface can fit on the ground, and a shovel plate 42 is connected to the bottom side of the end of the sewage suction head 41, and a baffle 43 is arranged on each side of the shovel plate 42, and the two baffles 43 are respectively connected to the two side plates of the sewage suction head 41, and the baffle 43 is rotatably arranged at the end of the sewage suction head 41, and a flap 44 is rotatably arranged on the top of the end of the sewage suction head 41 away from the opposite side of the shovel plate 42, and the flap 44 can rotate relative to the baffle 43, that is, the shovel plate 42, the two side plates and the flap 44 form an energy-saving structure at one end of the sewage suction head. The trumpet head structure is deformable, and a plurality of connecting sub-plates 45 are arranged on the inner side of the baffle plate 43 along the axial direction of the suction head, and the edges of the long sides (radial direction of the suction head) of each connecting sub-plate 45 are overlapped in sequence to form a deformed plate, and the other end of the connecting sub-plate 45 is arranged on the shovel plate 42 in a sliding manner, so that through the swing of the baffle plate 43, each connecting sub-plate 45 slides on the shovel plate 42 but the whole still forms a plate. Specifically, in this embodiment, the outer end of the shovel plate 42 is provided with an inclined surface, and the inner surface of the shovel plate 42 is symmetrically provided with T-shaped blocks, and the bottom surface of the connecting sub-plate 45 is provided with a T-shaped groove, and the T-shaped block is slidably arranged in the T-shaped groove. When working, the feces suction pump 2 is first used to connect the feces suction head. Negative pressure is generated inside 41 to suck up feces, and the shovel plate 42 and the inclined surface provided on its outer end are in contact with the ground to facilitate scooping up feces, so that it is convenient for the suction mechanism to suck feces. In the first working mode, when the feces are less and do not fill the channel inside the suction head, the feces suction pump 2 has low power and the amount of feces sucked by the feces suction pump 2 is small. At this time, the pressure generated by the feces sucked by the feces suction pump 2 on the pressure regulating mechanism 5 is not enough to make the pressure regulating mechanism 5 work, so that the shovel plate 42 and the flap 44 are both in an undriven state with the suction head 41. At this time, the shovel plate 42 and the flap 44 are arranged parallel to the axis of the suction head. At this time, the feces suction pump 2 normally sucks feces through the suction head 41; in the second working mode, when the feces are more and begin to fill the channel inside the suction head, the feces suction pump 2 will suck up feces normally. When the passage inside the head is opened, the power of the feces suction pump 2 increases, and the amount of feces sucked by the feces suction pump 2 is more than the amount of feces sucked by the feces suction pump 2 in the first working mode. At this time, the feces sucked by the feces suction pump 2 impacts the flap 44, and the flap 44 is impacted to generate pressure on the pressure regulating mechanism 5, but the pressure is not enough to make the pressure regulating mechanism 5 fully work. At this time, the pressure regulating mechanism 5 only drives the flap 44 to rotate along the sewage suction head 41 (that is, the flap 44 opens outward and forms an angle with the side wall of the sewage suction head 41, and the baffle 43 is still parallel to the side wall of the sewage suction head 41). After the opening between the sewage suction head 41 and the flap 44 becomes larger, it is convenient for the feces suction pump 2 to absorb more feces through the sewage suction head 41 at the same time.In the third working mode, when there is a lot of feces, which fills the channel inside the suction head and flows at a fast speed, the power of the feces suction pump 2 continues to increase (even the power of the feces suction pump 2 continues to be opened to the limit state for a period of time), and the amount of feces sucked by the feces suction pump 2 is greater than the amount of feces sucked by the feces suction pump 2 in the second working mode. At this time, the feces sucked by the feces suction pump 2 generates pressure on the pressure regulating mechanism 5 and makes the pressure regulating mechanism 5 fully work. At this time, the pressure regulating mechanism 5 drives the flap 44 and the baffle 43 to rotate along the suction head 41 (that is, the flap 44 opens outward and forms an angle with the side wall of the suction head 41, and the baffle 43 also forms an angle with the side wall of the suction head 41). When the baffle 43 rotates, the connecting sub-plate 45 slides along the shovel plate 42, so that the multiple connecting sub-plates 45 are arranged in a plane parallel to the shovel plate 42 to avoid leakage during feces suction. The opening formed between the suction head 41 and the flap 44 and the baffle 43 becomes larger, so that the feces suction pump 2 can suck more feces through the suction head 41 at the same time than in the second working mode. ;

[0034] In another embodiment provided by the present invention, the pressure regulating mechanism 5 includes a sliding block 51, which is slidably arranged in the middle of the top plate of the suction head 41, and the sliding block 51 is connected to the flap 44 by a wire rope 52. A support plate 53 is provided on the suction head 41, and two rollers 54 are arranged in parallel at the upper end of the support plate 53 in a rotating manner. The middle part of the wire rope 52 is arranged between the two rollers 54, and a pressure sensor 55 is arranged on the side of the sliding block 51 close to the pipe 3. Specifically, in this embodiment, a slide groove is opened in the middle of the top plate of the suction head 41, and the sliding block 51 is set in the chute by sliding, and a sliding plate is set at the inner end of the sliding block 51, and the sliding plate is used to block the chute to prevent feces from overflowing from the chute. When the present embodiment is working, feces are sucked by the feces suction pump 2. During the feces collection process, when the flow rate of feces is large and fills the internal space of the sewage suction head 41, the feces will generate pressure on the sliding block 51 and drive the sliding block 51 along the chute away from the flap 44, so that the steel wire rope 52 pulls the flap 44, so that the flap 44 rotates along the end of the sewage suction head 41, so that an angle is formed between the flap 44 and the side wall of the sewage suction head 41. , which is convenient for the sewage suction component 4 to suck more feces. During the process of the steel wire rope 52 driving the flap 44 to rotate, the steel wire rope 52 is guided and limited by the rollers 54 arranged in parallel at the upper end of the support plate 53. When the pressure generated by sucking feces drives the sliding block 51 to move along the slide groove to the limit position (that is, when the side of the sliding block 51 is attached to the other end surface of the slide groove), the steel wire rope 52 drives the flap 44 to rotate to the limit position, and the pressure sensor 55 is subjected to pressure and sends a signal, so that the pressure regulating mechanism 5 is fully operational, thereby driving the baffle 43 to rotate along the sewage suction head 41, so that the shovel plate 42, the baffle 43 and the The opening between the flaps 44 becomes larger, which makes it easier for the feces suction pump 2 to suck more feces at the same time. After the feces are sucked, the pressure on the sliding block 51 generated when sucking the feces disappears. At this time, the flap 44 rotates and resets due to its own gravity. The flap 44 drives the sliding block 51 to move and reset along the slide groove through the wire rope 52. At the same time, the pressure sensor 55 cannot detect the pressure and does not send a signal, so that the pressure regulating mechanism 5 drives the baffle 43 to rotate and reset in the opposite direction, which is convenient for the adaptive change of the sewage suction component 4 to suck feces, reduces the suction of a large amount of air while sucking feces due to excessive opening, and improves the efficiency of the sewage suction mechanism in sucking feces.

[0035] In another embodiment provided by the present invention, further, a sealing plate 510 is provided at the inner end of the sliding block 51, and the sealing plate 510 includes a horizontal section and a vertical section. Specifically, when the feces suction pump 2 extracts feces through the sewage suction head 41, the feces enters the sewage suction head 41 and squeezes the vertical section of the sealing plate 510, thereby driving the sliding block 51 to move along the slide groove. At this time, the sliding block 51 drives the horizontal section of the sealing plate 510 to move at the same time, so that the horizontal section of the sealing plate 510 can seal the slide groove provided in the middle part of the sewage suction head 41 to avoid leakage when the sewage suction head 41 sucks feces. When the pressure of the vertical section of the sealing plate 510 squeezed by the sucked feces increases, the vertical section of the sealing plate 510 drives the sliding block 51 to move to the edge of the slide groove and enables the sensor to detect the pressure.

[0036] In another embodiment provided by the present invention, the pressure regulating mechanism 5 also includes two linear motion components 56 arranged in parallel on the sides of the sewage suction head 41, and a pull rod 57 is arranged between each linear motion component 56 and the baffle 43. Specifically, when the pressure generated by the feces suction pump 2 sucking feces drives the sliding block 51 to move along the slide groove to the extreme position, the wire rope 52 drives the flap 44 to rotate to the extreme position, and at the same time, the pressure sensor 55 is subjected to pressure and sends a signal, so that the linear motion component 56 works after receiving the signal, so that the linear motion component 56 drives the baffle 43 to rotate and open along the sewage suction head 41 through the pull rod 57, so that the feces suction pump 2 can suck more at the same time. When the pressure generated by the feces suction pump 2 sucking the feces is not enough to drive the sliding block 51 to move along the slide groove to the extreme position, the pressure sensor 55 cannot detect the pressure and does not send out a signal. At this time, the linear motion component 56 cannot receive the signal and occurs in the opposite working state to when the signal is received, so that the linear motion component 56 drives the baffle 43 to rotate in the opposite direction along the sewage suction head 41 through the pull rod 57, so that the baffle 43 is reset to a state parallel to the side wall of the sewage suction head 41, ensuring that the space formed by the shovel plate 42, the baffle 43 and the flap 44 is fully filled when the feces is sucked, reducing the amount of air sucked by the feces pump 2 while sucking the feces, and improving the efficiency of the sewage suction mechanism in sucking feces.

[0037] In another embodiment provided by the present invention, the sewage suction component 4 also includes a limiting component 46 and a supporting component 47. The baffle 43 and the flap 44 are connected to each other through the limiting component 46. Two supporting components 47 are arranged in parallel on the upper end of the sewage suction head 41. The supporting component 47 is used to support and limit the limiting component 46. Specifically, when the power of the feces suction pump 2 increases, the amount of feces sucked increases, and the pressure generated by the suction of feces on the sliding block 51 increases, the sliding block 51 slides along the slide groove and drives the flap 44 to rotate and open through the wire rope 52. If the pressure sensor 55 detects the pressure and sends a signal, the linear motion component 56 drives the baffle plate 43 to rotate and open along the suction head 41 through the pull rod 57. At this time, a gap is generated between the flap 44 and the baffle plate 43. When sucking feces, a large amount of air is easily sucked in and the sucked feces are easily leaked. By setting a limiting component 46 between the two to fill the gap, the gap generated between the flap 44 and the baffle plate 43 after the two are opened can be effectively avoided, and a large amount of air is sucked in when sucking feces. At the same time, the leakage of sucked feces is reduced or even avoided. At the same time, the middle part of the limiting component 46 is supported and limited by the supporting component 47 to avoid feces squeezing and damaging the limiting component 46 during suction.

[0038] In another embodiment provided by the present invention, the limiting component 46 includes a storage plate 461, a reel 462 is rotatably provided inside the storage plate 461, a waterproof felt cloth 463 is rolled up on the reel 462, the open end of the waterproof felt cloth 463 is connected to the baffle 43, and a coil spring 464 is provided at one end of the reel 462 close to the sewage suction head 41. Specifically, when the power of the feces suction pump 2 increases, the amount of feces sucked increases, and the pressure generated by the suction of feces on the sliding block 51 increases, the sliding block 51 slides along the slide groove and drives the flap 44 to rotate and open through the wire rope 52. At this time, the waterproof felt cloth 463 is pulled out from the storage plate 461, and the waterproof felt cloth 463 drives the reel 462 to rotate and squeeze the coil spring 464, so that the waterproof felt cloth 463 is between the flap 44 and the baffle 43. The gap is sealed to reduce or even avoid leakage of feces from the gap between the flap 44 and the baffle 43 when sucking feces. When the amount of feces sucked is reduced or completed, the pressure received by the sliding block 51 is reduced, and the flap 44 rotates and resets due to its own gravity. The flap 44 drives the sliding block 51 to move and reset through the wire rope 52. At this time, the coil spring 464 drives the winding roller to rotate in the opposite direction, so that the winding roller rotates and winds up the waterproof felt cloth 463, so that the waterproof felt cloth 463 always seals the gap between the flap 44 and the baffle 43, and at the same time avoids the waterproof felt cloth 463 from extending too much to cause wrinkles and stacking. Even if it gets stuck or the coil spring fails after long-term use, the stacked waterproof felt cloth 463 can still be used normally when stretched, and only has a slight negative impact on suction when stacked, so it is more durable.

[0039] In another embodiment provided by the present invention, the support assembly 47 includes a fixed frame 471, two fixed frames 471 are arranged in parallel on the sewage suction head 41, and each of the fixed frames 471 is rotatably provided with a rotating frame 472, and a limit roller 473 is rotatably provided on the rotating frame 472, and an adjusting block 474 is slidably provided on the rotating frame 472, and the adjusting block 474 is slidably provided on the sewage suction head 41, and the adjusting block 474 is provided on the linear motion assembly 56. Specifically, when the sliding block 51 slides along the slide groove and drives the flap 44 to rotate and open through the wire rope 52, the pressure sensor 55 detects the pressure and sends a signal, and the linear motion assembly 56 drives the baffle 43 to rotate and open along the sewage suction head 41 through the pull rod 57. At this time, the waterproof felt cloth 463 continues to be pulled out from the storage plate 461, and the waterproof felt cloth 463 drives the winding shaft 462 to continue to rotate and squeeze the coil spring 464, so that the waterproof felt cloth 46 3, the gap between the flap 44 and the baffle 43 is sealed, so as to reduce or even avoid the leakage of feces from the gap between the flap 44 and the baffle 43 when sucking feces, and at the same time, the linear motion component 56 drives the adjustment block 474 to move along the suction head 41 toward the direction of the pipeline 3, that is, away from the flap and the baffle, so that the adjustment block 474 drives the rotating frame 472 to rotate with the connection point with the fixed frame 471 as the axis, so that the side of the rotating frame 472 close to the baffle 43 is tilted, and the limiting roller 473 provided on the rotating frame 472 is rotated to limit the waterproof felt cloth 463 on the rotating frame 472, ensuring that the rotating frame 472 always supports the waterproof felt cloth 463, thereby strengthening the structural strength of the waterproof felt cloth 463, so that the waterproof felt cloth 463 seals the gap between the flap 44 and the baffle 43, reducing or even avoiding the leakage of feces from the gap between the flap 44 and the baffle 43 when sucking feces.

[0040] In another embodiment provided by the present invention, an L-shaped groove is provided on one side of the rotating frame 472 close to the pipe 3, and a pin is provided on the adjusting block 474, which is slidably arranged in the L-shaped groove, and the angle between the vertical section and the horizontal section of the L-shaped groove is greater than 90 degrees, and the vertical section and the horizontal section of the L-shaped groove are provided with rounded corners. Specifically, when the linear motion component 56 drives the adjusting block 474 to move in a straight line along the suction head 41, the angle between the vertical section and the horizontal section of the L-shaped groove is greater than 90 degrees, and the rounded corners provided at the corners of the two enable the linear motion component 56 to drive the pin provided on the adjusting block 474 to slide from the vertical section of the L-shaped groove to the horizontal section, and the adjusting block 474 can move in the vertical direction relative to the linear motion component 56, that is, perpendicular to the horizontal section, because the sliding nature of the pin in the vertical section of the L-shaped groove is horizontal and inclined. The adjusting block 474 moves in both oblique directions, while the linear motion component 56 only drives in the horizontal direction. Structurally, a vertical slot can be provided on the adjusting block 474, and the linear motion component drives the adjusting block to move horizontally by inserting a column into the vertical slot. Since the column can move vertically along the vertical slot during horizontal movement, the adjusting block 474 can move vertically relative to the linear motion component 56, so that the adjusting block 474 lifts the end of the rotating frame 472 close to the baffle 43 to support the waterproof felt cloth 463, and after the feces absorption amount is reduced or completed, the pin provided on the adjusting block 474 moves from the horizontal section to the vertical section in the L-shaped slot, so that the adjusting block 474 drives the end of the rotating frame 472 close to the baffle 43 to reset, so that the winding spring 464 drives the winding shaft 462 to rotate and wind up the waterproof felt cloth 463.

Specifically, the end of the clamping plate 4711 close to the rotating frame 472 is provided with a rounded corner. When this embodiment is working, when the linear motion component 56 drives the rotating frame 472 to rotate through the adjusting block 474, the end of the rotating frame 472 close to the baffle 43 is tilted to support the waterproof tarpaulin 463, and at the same time, the part of this section of the rotating frame 472 close to the rotation center is separated from the clamping plate 4711, so that the clamping spring 4712 squeezes the clamping plate 4711 slides toward each other along the fixed rod 4710, so that the clamping plate 4711 clamps the waterproof felt cloth 463 on one side close to the end of the suction head 41 to avoid leakage when sucking feces. After the rotating frame 472 rotates and resets, the rotating frame 472 squeezes the clamping plate 4711 near the rotation center, so that the clamping plate 4711 squeezes the clamping spring 4712, so that the clamping plates 4711 move away from each other to unlock the waterproof felt cloth 463, making it convenient for the winding spring 464 to drive the winding shaft 462 to rotate and wind up the waterproof felt cloth 463, and the rounded corners on the clamping plate 4711 facilitate the rotating frame 472 near the rotation center to squeeze into between the clamping plates 4711.

Specifically, the adjusting block 474 is threaded. The pressure sensor 55 is arranged on the outside of the first transmission rod 561 in a combined manner. When the present embodiment is working, the pressure sensor 55 detects the pressure and sends a signal to the driving motor 564. After receiving the signal, the driving motor 564 drives the driving gear 565 to rotate, so that the driving gear 565 drives the two driven gears 563 to rotate at the same time, so that the two driven gears 563 respectively drive the first transmission rod 561 and the second transmission rod 562 to rotate, and then the first transmission rod 561 drives the adjustment block 474 to move, so that the adjustment block 474 squeezes the rotating frame 474. 2 is close to the side of the pipe 3, so that the side of the rotating frame 472 close to the baffle 43 is tilted, ensuring that the rotating frame 472 always supports the waterproof felt cloth 463, the second transmission rod 562 rotates to drive the pull rod 57 to move, so that the pull rod 57 drives the baffle 43 to rotate and expand, increasing the opening of the sewage suction component 4, so as to facilitate the suction of more feces, when the pressure sensor 55 cannot detect the pressure, the driving motor 564 cannot receive the signal, and the driving motor 564 drives the driving gear 565 to rotate in the opposite direction, so that the driving gear 565 drives the two driven gears at the same time 563 rotates in the opposite direction, so that the two driven gears 563 respectively drive the first transmission rod 561 and the second transmission rod 562 to rotate in the opposite direction, so that the adjustment block 474 approaches the rotation center of the rotating frame 472, so that the side of the rotating frame 472 close to the baffle 43 is reset (that is, the side of the rotating frame 472 close to the baffle 43 is parallel to the side wall of the suction head 41, and the side of the rotating frame 472 close to the pipe 3 is tilted), and at the same time, the second transmission rod 562 drives the pull rod 57 to move and reset, so that the pull rod 57 drives the baffle 43 to rotate to a position parallel to the side wall of the suction head 41.

[0043] In another embodiment provided by the present invention, preferably, the linear motion assembly 56 also includes a limit plate 566, and the limit plate 566 is arranged in the mounting plate 560. A threaded block 567 is arranged on the side of the second transmission rod 562 close to the flap 44 by threaded cooperation. A limit spring 568 is arranged between the limit plate 566 and the threaded block 567. Specifically, after the drive motor 564 receives the signal, the drive motor 564 drives the drive gear 565 to rotate, so that the drive gear 565 drives the second transmission rod 562 through the driven gear 563 arranged on the second transmission rod 562. The second transmission rod 562 rotates, so that the second transmission rod 562 drives the threaded block 567 to move in the direction close to the pipe 3, so that the threaded block 567 drives the baffle 43 to rotate and expand through the pull rod 57. When the threaded block 567 moves to fit one end of the limit spring 568, the threaded block 567 and the thread on the second transmission rod 562 are no longer matched (that is, the threaded block 567 is in a position where no thread is set on the second transmission rod 562), so that the threaded block 567 drives the pull rod 57 to always be in this position, ensuring that the driving gear 565 is connected to the driven gear 565 through the first transmission rod 561. 63 drives the first transmission rod 561 to continue to rotate, so that the first transmission rod 561 drives the adjustment block 474 to continue to squeeze the side of the rotating frame 472 close to the pipe 3, ensuring that the side of the rotating frame 472 close to the baffle 43 is tilted to support and limit the waterproof felt cloth 463. After the pressure sensor 55 cannot detect the pressure and the driving motor 564 cannot receive the signal, the driving motor 564 drives the driving gear 565 to rotate in the opposite direction, so that the driving gear 565 drives the two driven gears 563 to rotate in the opposite direction at the same time, so that the two driven gears 563 respectively drive the first transmission rod 561 and the second The transmission rod 562 rotates in the opposite direction, and the first transmission rod 561 drives the adjustment block 474 to reset, so that the rotating frame 472 is reset. At the same time, the limit spring 568 squeezes the threaded block 567, so that the threaded block 567 and the thread provided on the second transmission rod 562 are re-matched, so that the second transmission rod 562 drives the threaded block 567 to move and reset, so that the threaded block 567 drives the baffle 43 to rotate and reset through the pull rod 57 (that is, the baffle 43 rotates to a position parallel to the side wall of the suction head 41), thereby reducing the opening of the suction assembly 4, which can effectively avoid sucking in a large amount of air when sucking feces.
