Referring to fig. 5a, in the actual working process of the present invention, when the dung scraping device is in the initial state, the shift lever of the steering fixing mechanism is in the right-leaning state, the left end of the steering push key is driven to be keyed into the stepping hole of the guide rail mechanism, and the guide rail mechanism is in the right process of the reciprocating motion and drives the steering fixing mechanism to move to the right.
Referring to fig. 5b, in the process that the long push-pull rod moves to the left in a reciprocating manner, one side of the stepping hole extrudes the steering pushing key out of the stepping hole, the steering fixing mechanism is stationary at the moment, and the guide rail mechanism moves to the right again and drives the steering fixing mechanism to continue to move to the right after the left end of the steering pushing key is keyed into the next stepping hole in the process that the guide rail mechanism moves to the left.
Referring to 5 b-e, when the steering fixing mechanism moves to the head end of the long push-pull rod, the guide rail mechanism enters a reciprocating leftward process, the steering pushing key is extruded out of the stepping hole by one side of the stepping hole, the reversing stop lever at the head end of the long push-pull rod pushes the shifting rod leftwards along with the guide rail mechanism to incline leftwards, the steering pushing key is driven to rotate clockwise, the right end of the steering pushing key falls down, finally the steering pushing key is keyed into the stepping hole along with the reciprocating motion of the guide rail mechanism, and the steering fixing mechanism repeatedly moves leftwards in a rightward pushing process. The left moving process of the steering fixing mechanism is the same as the right moving process, and the steering process after the steering fixing mechanism moves to the tail end of the guide rail mechanism is the same as the steering process after the steering fixing mechanism moves to the head end.
Referring to fig. 6 a-b, when the dung scraping main board 31 moves leftwards to the end of the guide rail mechanism 4 along with the steering fixing mechanism 2, the overturning push rod 44 pushes the dung scraping main board 31 to rotate clockwise to tilt up the dung scraping main board, and at this time, the steering fixing mechanism 2 finishes steering and drives the dung scraping main board 31 to move rightwards.

The deflector rod in the steering fixing mechanism of the embodiment extends out of the steering fixing mechanism from the side face of the shell, and when the dung scraping interval is too long due to power failure or fault, even if the final dung is accumulated too high, the situation that the dung in front is squeezed into the steering fixing mechanism through an opening in the front of the steering fixing mechanism due to too large pressure can be avoided in the stepping process, so that the reliability of the dung scraping device is improved; the double-layer structure of the shell is used as a first layer of obstruction for the excrement to enter the steering fixing mechanism, and provides certain buffer between the inside of the steering fixing mechanism and the excrement, so that the excrement cannot enter the steering fixing mechanism at the first time, and when the excrement is accumulated too much and the pressure at the front opening of the shell is too high, the pressure for the excrement to finally enter the steering propulsion mechanism can be reduced; the front and back shapes and sizes of the shell are consistent with the cross section of the long push-pull rod, and the limiting wheel, the supporting wheel and the bottom scraping blade are arranged in the open hole, and the limiting wheel, the supporting wheel and the bottom scraping blade jointly form a second layer of block for the excrement to enter the steering fixing mechanism; scrape the upset driving lever that sets up on the excrement mainboard under the promotion of long push-and-pull rod both ends upset driving lever, can realize scraping the excrement machine and put down when scraping excrement forward stroke and scrape the excrement mainboard, the excrement mainboard is scraped to the perk when reverse stroke, avoids scraping the phenomenon that the excrement mainboard was scraped in reverse stroke in-process, has improved and has scraped excrement efficiency.
Example 2:
referring to fig. 7, this embodiment is substantially the same as embodiment 1 except that: the front outer plate 213 of the steering fixing mechanism 2 is inclined to the trench floor surface, and the upper side distance between the front outer plate 213 and the front inner plate 212 is smaller than the lower side distance.
Compare in embodiment 1, because the contained angle that turns to fixed establishment bilayer structure's preceding planking and ground is the acute angle in embodiment 2, has reduced the pressure between excrement dirt and the bilayer structure, and the cavity of bilayer structure inside also makes excrement dirt drop more easily simultaneously.
Example 3:
referring to fig. 8 and 9, this embodiment is substantially the same as embodiment 1, except that: one end of the deflector rod 22 extends out of the machine shell 21, the other end of the deflector rod 22 is welded with the middle part of the steering pushing key 23 in the machine shell 21, and the deflector rod 22 can be pulled to drive the internal steering pushing key 23 to turn over in the same direction.
The steering push button 23 has a protrusion at each end, which is keyed into the step hole 41 of the long push-pull rod 44 to drive the steering fixing mechanism 2 to move together when the long push-pull rod 44 is pushed from one end, but one end of the steering push button 23 is pushed out by the edge of the step hole 41 when the long push-pull rod 44 is pushed from the other end.
Referring to fig. 10a to d, the operation of forward manure cleaning, steering and backward homing in this embodiment is substantially the same as that in embodiment 1, and will not be described more.
Compared with embodiment 1, in embodiment 2, because the shift lever 22 and the steering push key 23 are connected by welding, the rust generated after long-term use does not affect the operation of the embodiment, and the reliability is increased.
Example 4:
referring to fig. 11 to 12, the embodiment is substantially the same as embodiment 3, except that: the side opening of the machine shell 21 is a straight notch-shaped hole 211, the diameter of the semicircle at the two ends of the straight notch-shaped hole is the same as the axial diameter of the deflector rod 22, the distance between the centers of the two semicircles is less than the depth of the key-in stepping hole of the steering push key, and the deflector rod 22 is tightly attached to the interior of the machine shell and is provided with a baffle 211.
Compared with the embodiment 3, the deflector rod 22 can drive the steering pushing key 23 to shake up and down in a certain direction in the operation process of the embodiment 4, when excrement forms a layer of film in the stepping hole, the tip of the shaking steering pushing key 23 is continuously contacted with the film to break the film, so that the structure has a stronger film breaking effect, the stepping hole can be easily keyed in, and the reliability of the stepping process is ensured.
Example 5:
referring to fig. 13, this embodiment is substantially the same as embodiment 1 except that: the steering push key 23 is a non-sealed hollow structure, and a roller 232 is clamped in the hollow structure and can slide along the hollow structure.
Compared with the embodiment 1, the steering push key 23 with the hollow structure in the embodiment 5 is easier to key into the stepping hole 41 under the driving of the roller, and the reliability is further improved.
Example 6:
referring to fig. 14, this embodiment is substantially the same as embodiment 1 except that: the steering push button 23 has a closed cavity 234, and a ball 233 is caught in the cavity 234 and is slidable in the cavity 234.
Compared with example 5, the steering push button 23 having the cavity 234 in example 6 does not affect its normal operation even if rusted on the outside, and is more suitable for a highly corrosive environment such as a pigsty.
Example 7:
this example is basically the same as example 6, except that: the cavity 234 is impervious, corrosion resistant and scratch resistant and the mercury is contained in the cavity 234.
Compared with embodiment 6, embodiment 7 has the cavity 234, and the operation of the whole device is not affected by the rust generated inside the cavity of the steering push key 23, and the reliability is further improved.
