A plurality of positioning holes 35 are uniformly formed in the upper surface of the guide rail along the length direction thereof, i.e., the front-rear direction, and are used for advancing, retreating and reversing the reversing box body.

And the reversing box body 1 is arranged on the guide rail and can freely slide along the direction of the guide rail. In the in-service use process, need realize the switching-over box is moved to another tip by one end of guide rail, moves back from another tip again, makes the clearance of scraping excrement and urine of excrement and urine arm subassembly in the pig house on the switching-over box through the removal that makes a round trip.

In the embodiment, the reversing box body 1 comprises a box body, and a dung scraping arm component 2 is connected to one side or two sides of the box body. If when the track setting is in one side of pig house fecal treatment groove, only can scrape the excrement arm subassembly in one side setting of box, when the track setting is in the centre of pig house fecal treatment groove, then need all set up in the both sides of box and scrape the excrement arm subassembly. In this embodiment, a dung scraping arm assembly is arranged on both sides of the box body.

The box body comprises a plurality of parts, and firstly comprises a box body 11, and a positioning mechanism 12 is arranged in the box body and is used for driving the box body to move forwards or backwards when the guide rail mechanism reciprocates.

The box body comprises four side plates 111 which are arranged at the front, the rear, the left side and the right side, two bottom plates 112 are arranged at the bottoms of the two left and right sides, the left side plate is connected with the left bottom plate (welded or screwed), and the right side plate is connected with the right bottom plate (welded or screwed). And the front and rear side plates are connected (welded or screwed) with the left and right side plates to form a frame of the box body.

The front reversing block and the rear reversing block are S-shaped, and the short parts of the front reversing block and the rear reversing block are arranged oppositely. The reversing pin 16 is locked in the middle of the front reversing block and the rear reversing block, so that the front reversing block and the rear reversing block can rotate along the reversing pin. The short parts of the front reversing block and the rear reversing block can be inserted into the positioning holes of the guide rails, and the short parts of the front reversing block and the rear reversing block can be clamped in the positioning holes or separated from the positioning holes by applying pressure to the high parts of the front reversing block and the rear reversing block through the pressure roller 17.

For example, when the front reversing block needs to move forwards, the high end of the front reversing block is pressed by a pressing roller, so that the low end of the front reversing block is positioned in the reversing hole and cannot rotate. And the pressure roller of the rear reversing block is pressed in the middle of the rear reversing block, so that the short end of the rear reversing block is separated from the positioning hole. When the guide rail moves forwards, the whole reversing box body is driven to move forwards through the front reversing block, the guide rail needs to do backward reciprocating motion after the forward movement is finished, when the guide rail moves backwards, the reversing box is in a static state, namely, when the guide rail moves backwards, the short end of the front reversing block can be lifted up and cannot move along with the guide rail, and when the guide rail moves backwards, the short end of the front reversing block can be located in the next positioning hole, so that when the guide rail moves forwards again, the reversing box body can be driven to move forwards again.

In addition, as an embodiment in this embodiment, the distance between two adjacent positioning holes is L, but the distance of the guide rail moving forward or backward each time is (L + s). Specifically, after the guide rail moves reversely each time, the reversing block is not located in the positioning hole, and the reversing block can be clamped in the positioning hole (namely, the reversing block is put into gear) only by the distance s when the guide rail moves forwards, and then the guide rail drives the reversing box to move forwards by the distance L. The reciprocating movement distance of the guide rail is (L + s), but the distance between two adjacent positioning holes is L, and the reversing box body only moves by the distance of L each time.

In addition, as another embodiment of the exemplary embodiment, a reversing slider 18 is also provided in the mounting region, which is located above the reversing block and also has a cavity which is open at the bottom or at both the top and bottom.

Namely, holes for the reversing arms to extend out are arranged on the front side plate and the rear side plate. In order to match the reversing of the reversing box body, reversing stoppers 36 matched with the reversing arms are fixedly arranged at the front end part and the rear end part of the guide rail.

As an implementation manner in this embodiment, the outer walls of the through holes of the front side plate and the rear side plate of the reversing box are respectively provided with a dust guard 113, the dust guard is provided with a hole through which the reversing arm passes, the dust guard is locked on the front side plate and the rear side plate by a screw, the inner wall of the hole of the dust guard is provided with a rubber ring 114, and the reversing arm contacts with the rubber ring when passing through the hole on the dust guard. If the dustproof cover is used, the gap can be eliminated, excrement and urine are prevented from entering the box body, friction between the reversing arm and the dustproof plate can be reduced, and the service life is prolonged.

In addition, the reversing arm is in threaded connection with the reversing sliding block, threaded holes are formed in the front side and the rear side of the reversing sliding block, external threads are formed in the end portion of the reversing arm, the reversing arm is screwed into the threaded holes, and nuts are further arranged on the external thread section of the reversing arm for fixing.

When the reversing box body in the embodiment is adopted, the slidable distance of the pressure roller wheel is s, the distance of the reversing arm is at least larger than s, when the reversing box body is positioned in the last positioning hole, the reversing arm just abuts against the reversing stop block, and when the guide rail moves in the reverse direction by the distance of s, the reversing stop block pushes the reversing arm to move forwards, so that the pressure roller wheel moves in the sliding groove by the distance of s, and the pressure roller wheel of the front reversing block and the pressure roller wheel of the rear reversing block just realize reversing. Namely, the pressure roller wheel of the front reversing block moves to the middle part, the front reversing block is separated from the positioning hole, the pressure roller wheel of the rear reversing block moves to the end head of the high part of the rear reversing block, so that the sharp end head of the low part of the rear reversing block is positioned in the positioning hole, and the guide rail can drive the reversing box body to move together when moving in the reverse direction for L. At this time, the reversing of the reversing box body is realized.
