Example 2:

A pig house, comprising the manure removal device for pig houses described in Example 1, and also comprising floor heating 7 for heating, wherein two ends of the floor heating 7 are symmetrically provided with two manure removal devices for pig houses , and the dry manure tank 4 is connected to the two ends of the floor heating 7. In addition, the wet manure tank cover 8 is provided above the wet manure tank 3, and when the wet manure tank cover 8 is in a vertical state, the wet manure tank The top of the cover plate 8 is located outside the pig house. In addition, the pig house of the present invention also includes a wet and dry manure separator, so as to perform solid-liquid separation treatment on the manure in the dry manure tank, and also includes a faucet for flushing the dry manure tank. In this way, the manure board, the dry manure tank and the wet manure tank are flushed after removing the manure, and a septic tank for storing urine is also included, wherein the urine in the wet manure tank directly flows into the septic tank For processing, the liquid separated by the wet and dry separator is discharged into the septic tank through the liquid pipeline of the separator for processing, and the separated feces are directly conveyed to the dung pulling truck, and then dried in the drying field. Pig house manure removal process.

The principle of use of the present invention: the pig house adopts the method of semi-leaching manure, and pigs are raised on both sides of the pig house, and the floor heating 7 is arranged in the middle to keep the pigs warm in winter. Specifically, the pigs excrete manure in the breeding area through the leaking manure. The board falls on the manure receiving board 1 below. Since the manure receiving board 1 is inclined, part of the urine falling with the feces flows into the wet manure tank 3. Since the wet manure tank 3 is inclined, the urine is in the wet manure The tank 3 flows into the septic tank;

Specifically, when a certain amount of feces is accumulated on the manure receiving board 1, the screw rod I54 is activated at this time, and the two screw rods I54 located at both ends of the manure receiving board 1 and parallel to the manure receiving board 1 are along the inclination direction of the manure receiving board 1. At this time, the screw rod I54 drives the first excrement scraper 51 and the second excrement scraper 52 located at the inclined low end of the excrement receiving board 1 to move in the initial state. During this process, the first excrement scraper 51 pushes the excrement The dry manure tank 4 moves in the direction. When the manure overflows the first manure scraper 51, the manure enters between the second manure scraper 52 and the first manure scraper 51. At this time, the second manure scraper 52 continues to push the manure forward. In this way, the leakage of feces is prevented and the efficiency of scraping feces is improved;

Specifically, during the upward movement of the first excrement scraper 51 and the second excrement scraper 52, the urine in the excrement flows into the first excrement scraper from the through hole 533 provided on the side end of the first excrement scraper 51 51, and then enter the channel I532 in the connecting plate 531 through the channel II534 in the first excrement scraper 51 in turn, and finally flow out into the wet manure tank 3 through the opening 535 of the channel II534 in the second excrement scraper 52. When the excrement overflows When reaching between the second excrement scraper 52 and the first excrement scraper 51, the urine in the excrement in contact with the second excrement scraper 52 enters the second excrement scraper 52 through the through hole 533 provided at the side end of the second excrement scraper 52. In the excrement scraper 52, it flows out into the wet manure tank 3 through the opening 535 of the channel II 534 in the second excrement scraper 52, wherein the connecting plate 531 is provided to reinforce the first excrement scraper 51 and the second excrement scraper 52 and is used to prevent the urine in the excrement located at the front end of the first excrement scraper 51 from entering the excrement located at the front end of the second excrement scraper 52, so as to improve the pretreatment efficiency of the excrement. The through holes 533 provided on the side end surfaces of the second excrement scraper 52 face the dung drying tank 4, and the through holes 533 are evenly distributed on the side end surfaces of the first excrement scraper 51 and the second excrement scraper 52. When the scraper 51 and the second feces scraper 52 are in contact with the feces, the urine in the feces can simultaneously flow into the through holes at various positions in the vertical direction of the side end faces of the first feces scraper 51 and the second feces scraper 52 533, reducing the time that urine deposits and flows out in feces, and further improves the pretreatment efficiency of feces;

Specifically, during the rotation of the screw rod I54, the screw rod I54 drives the driving wheel 553 to rotate, and the driving wheel 553 drives the column 554 to make a circular motion, thereby driving the cleaning plate 551 to reciprocate through the telescopic shaft 555 hinged with the column 554. , and then, the dung board 1 is cleaned by the brush 552 at the bottom of the cleaning board 551 to improve the dung scraping effect;

Specifically, when the first excrement scraper 51 and the second excrement scraper 52 move to the dry excrement tank 4 , the first excrement scraper 51 pushes the excrement into the dry excrement tank 4 and is located on the second excrement scraper 52 The excrement between the first excrement scraper 51 is pushed into the dry excrement tank 4 from the gap between the two connecting plates 531;

Specifically, when the excrement enters the dry manure tank 4, the screw II 61 is activated at this time, and the rotating screw II 61 drives the third excrement scraper 6 to move, so as to push the excrement out of the dry manure tank 4. During this process , the screw II 61 drives the rotating gear 621 located in the third excrement scraper 6 to rotate, thereby driving the stirring column 622 to rotate, and the stirring column 622 with the screw conveying plate 623 pre-dredges the excrement in the dry manure tank 4 to prevent excrement. It is too hard to cause the third excrement scraper 6 to be pushed poorly, and to prevent excessive excrement from causing the excrement to overflow the third excrement scraper 6 and affecting the excrement pushing efficiency;

Specifically, the excrement is pushed into the excrement wet and dry separator through the third excrement scraper 6 for processing. The excrement dry and wet separator adopts the dry and wet separation device in the background art. The liquid pipeline of the fecal dry and wet separator is discharged into the septic tank for processing, and the separated feces are directly conveyed to the feces pulling truck, and then sent to the drying yard for drying;

Specifically, after the third excrement scraper 6 pushes the excrement into the excrement wet and dry separator, the faucet is used to connect the excrement board 1, the wet excrement tank 3, the dry excrement tank 4 and the excrement removal mechanism 5 for flushing, and the flushing liquid flows into in a septic tank;

Specifically, by regularly opening the wet manure tank cover 8 in winter to carry out ventilation in the pig house, the air intake from below and above is conducive to the elimination of a large amount of ammonia generated in the pig house, wherein the wet manure tank is opened in summer. When the cover plate 8 is closed, the natural wind passes through the pig house to ventilate and cool the pig house, and when the wet manure tank cover plate 8 is closed, it can keep warm well.

Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, and substitutions can be made in these embodiments without departing from the principle and spirit of the invention and modifications, the scope of the present invention is defined by the appended claims and their equivalents.
