BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a livestock dung transporting apparatus for operating a paddle at the time of forward or backward movement in a discharge pit of a livestock barn to scrape and excrete manure in the discharge pit.

[0002]

2. Description of the Related Art Conventionally, in a barn or the like in which livestock is arranged in one direction, a collecting pit is provided on a side of each livestock in order to collect and remove livestock excreta. The excrement dropped into the accumulation pit is raked up by reciprocatingly sliding a scraper formed of a rigid body such as an iron plate in the pit, and is accumulated in one discharge pit.

As shown in FIG. 8, a transport rail 3 extends on a bottom surface 1a of the discharge pit 1, and a cleaner unit 5 is provided at a specific position of the transport rail 3.
On one side of the cleaner unit 5, a plurality of paddles 7 that are operated and opened when going forward or backward are provided. A plurality of stays 10 are provided above the transport rail 3.
And a top guide rail 9 is fixed in parallel with the side surface 1 b of the discharge pit 1.
A guide stay 8 fixed by an anchor bolt 42 or the like is engaged and supported so as to be slidable in parallel to the side surface 1b, thereby forming a discharge device 6.

In such a discharge device 6, when the transport rail 3 is reciprocated at a constant stroke by a hydraulic cylinder or the like (not shown), if the transport rail 3 moves in one direction (rightward in the figure), a paddle is required. When the leg 7 is opened and the excrement is pushed and moved, and when it moves to the other side (left direction in the figure), the paddle 7 is closed at the position 7a and returns to the original position without pushing the excrement back. Repeatedly, the manure was gradually moved to one side (right direction in the figure) and dropped into the manure tank.

[0005]

However, in such a single-side operation type discharge device 6, if the width of the discharge pit 1 is increased in order to discharge a large amount of manure,
Although it is necessary to lengthen the paddle 7 in order to prevent unscraping, there is a limit to the stroke of the reciprocating motion. Therefore, the paddle 7 cannot be so long because the paddle 7 must be reliably opened and closed. Therefore, the width of the discharge pit 1 cannot be widened, and the discharge amount cannot be increased so much.
There was a problem. Then, even if the discharge device 6 of the one-side operation type is used, the paddle 7
However, there is a problem that even if the operating range is expanded by projecting the two, two sets of discharging devices 6 are required, and the equipment cost is increased.

As shown in FIG. 7, a guide rail 2 is laid approximately at the center of the bottom surface 1a of the discharge pit 1, and a slider 4 is slidably mounted over the guide rail 2. The transport rail 3 is fixed to the upper surface of the slider 4 with a fastener such as a bolt. The slider 4 has a lower surface in contact with the bottom surface 1a of the discharge pit 1 and moves while sliding on the bottom surface 1a. On the other hand, the discharge pit 1 is usually formed of concrete or the like. I have. Therefore, each time the slider 4 reciprocates, the lower surface of the slider 4 scrapes the surface of the concrete bottom surface 1a, and the bottom surface 1a needs to be repaired frequently, thereby avoiding an increase in repair cost. In addition, there is a problem that during the repair, the manure must be removed manually, and the physical burden on the operator is large. Further, as described above, the slider 4 has the bottom surface 1a.
When reciprocating while shaving, paddle 7 also rocks violently,
There was also a problem that manure left behind increased.

[0007]

When the transport rail 22a moves in one direction (to the right in FIG. 5), the friction between the lower surface of the paddle 38 and the lower surface 20a of the discharge pit 20 is generated. Due to the resistance, the paddle 38 is opened by approximately 90 degrees around the engaging pin 38a, and while sliding on the lower surface 20a, the accumulated manure is scraped and conveyed to the manure tank 12 side. When the transport rail 22a moves to the other side (to the left in FIG. 5), the paddle 38 closes itself due to frictional resistance with the lower surface 20a, and the paddle 38 smoothly returns, and returns to the original standby position in the inoperative state. Like that.

By repeating this reciprocating operation, manure is gradually conveyed to the manure tank 12 side. As a result, when the manure reaches the end of the discharge pit 20, the manure is dropped into the manure tank 12 from the discharge port 27. is there. As described above, the paddle 38 is not completely closed by providing the leg closing restricting portion 38d so that the paddle 38
It is possible to prevent troubles such as the inability to open the legs due to the adhesion of glue-like excrement adhering to the side a.
