[0002]

2. Description of the Related Art Conventionally, in a pig house or the like in which a livestock is arranged in one direction, in order to collect and remove livestock excreta, generally, as shown in FIG. A pit 2 is provided along. The excrement dropped into the pit is raked by reciprocatingly sliding the scraper 3 formed of a rigid body such as an iron plate in the pit, and the feces are cleaned. This scraper 3 has a rope 4
, And is reciprocally driven along the surface of the pit 2 by the drive motor.

[0003]

However, since the feces removal pit is generally constructed of concrete, the dimensional error is about ± 1 cm due to an error in the construction, and the width is not exactly the same. Therefore, the width of the scraper made of a rigid body such as an iron plate must be smaller than the minimum width of the pit, and the clearance with the side wall of the pit is about 2 cm where the clearance is large. The droppings from the bed of the pens often fall not only directly on the bottom wall of the dropping pit but also along the pit side wall. Therefore, a lot of feces adhere to the pit side wall surface, but with the above-mentioned conventional scraper, the feces attached to the pit side wall can be left behind, and the feces rot and ferment at that part, causing odor and harmful gas,
It was a source of pests such as maggots. In addition, from the viewpoint of hygiene, there has been a problem of causing poor growth of livestock and causing disease.

Accordingly, the present invention is intended to solve the above problem, and effectively removes feces on the side walls of the pit even if there are errors in the width interval of the feces removing pits or irregularities on the wall surface. An object of the present invention is to provide a dung removal device for livestock pens having a scraper capable of removing dung in a pit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention is shown in FIGS.
Shown in The scraper 9 in the animal dung removal apparatus of the present embodiment slides in the pit 2 (FIG. 3) having a V-shaped bottom, and the main plate 10 is slightly smaller in size than the width of the pit 2. Side plates 11 are attached to both sides in a substantially H shape. A V-shaped bottom scraping portion 12 is formed integrally with the main plate 10 at the bottom, and a guide parallel to the side plate 11 is formed at the center. Plate 13 and drive rope attachment 1
4 are left and right L-shaped arms 15, 16 between the left and right side plates.
The guide plate 13 is also fixed between the main plate 10 and the bottom scraping portion 12 by appropriate means such as bolts and rivets. The guide plate 13 fits with a guide groove 17 provided also at the center of the V-shaped bottom of the pit and also serving as a liquid discharge (urine discharge) groove, and functions as a guide during sliding drive.

In the scraper having such a structure, according to the present invention, a helical spring 19 is provided at the end of the side plate 11 so that the side wall scraping member 18 is pressed against the side wall in the extending direction thereof.
The rotational force is applied via the. That is, the side wall scraping member 18 is rotatably attached to the end of the side plate 11 by a hinge 20 (FIG. 2) to which a rotational force is applied via a helical spring 19, and the leading edge thereof is attached to the pit side wall 7 by a spring. It has a structure to suppress by force. In this embodiment, the tip edge 18 'of the side wall scraping member 18 is formed in a circular cross section so that it can move smoothly along the side wall even if it is pressed against the side wall 7.

In the first embodiment, as shown in FIGS. 1 to 3, side wall scraping members are also provided at left and right positions behind the side plate 11. Although it is not always necessary to provide four side wall scraping members, by providing them in front and rear as in the present embodiment, the scraper does not tilt with respect to the pit during sliding driving, and can slide smoothly. It functions as a balancer for stabilizing the posture.

Next, a second embodiment of the livestock defecation apparatus of the present invention will be described with reference to FIG. The pressing mechanism by which the side wall scraping member slides in response to the unevenness of the pit side walls 7, 7 does not necessarily need to be limited to the rotational force, and has a structure in which the side wall scraping member can be slid diagonally forward. May be configured to press against the side wall. FIG. 4 shows a side wall scraping member 25 having a rod 21 extending to the other end of the scraping surface, a guide member 22 for guiding the rod slidably to the end of the side plate, and a side wall scraping member 25.
And a spring 26 for pressing the inner surface of the pit against the wall surface. When sliding in the pit, the side wall scraping member follows the unevenness of the pit wall surface and freely moves forward and backward.

FIG. 5 shows a main part of a third embodiment. In this configuration, the side wall scraping member 30 itself has a leaf spring structure, and the side wall scraping member is attached at an end of the side plate so as to be bent obliquely forward so as to apply a pressing force to the pit side wall. The side wall scraping member 30 is fixed to the side plate 11 via a long hole 31 by a bolt 24 or the like so that the degree of curvature of the side wall scraping member 30 can be adjusted. The adjusting mechanism may be any suitable means as long as it is a fixing method capable of adjusting the movement in one direction. In each of the above embodiments, the pit shape is a V-shaped pit. However, it goes without saying that the animal dung removal apparatus of the present invention can be applied not only to the V-shaped pit but also to pits having other cross-sectional shapes.
