Definitions
- a manure scraper having a pair of spaced support frames with a scraper blade pivotably mounted therebetween. Rigidly attached to each end of and pivotable with the scraper blade is a rigid panel adapted to slidably abut the bottom of the pit. The panel is circular in peripheral configuration such that it causes the blade to pivot to a non-working position when the device is pulled in a first direction and to a working position when the device is pulled in an opposite direction.
- This invention relates to manure scrapers and, more particularly, to manure scrapers particularly adapted for utilization in cleaning elongated animal refuse pits.
- This centralized collection area generally takes the form of an elongated pit of rectangular cross section.
- the dropping collection pit may be directly incorporated into the concrete floor structure of the poultry house when it is poured.
- upwardly standing side walls may be provided on an already existing floor into which the droppings may fall.
- a plurality of these scraper blades are provided and as the scraper mechanism is oscillated the droppings within the pit are selectively moved from one scraper to the next toward the discharge area. If the animal enclosures are not positioned directly above the pit, it is often desirable to periodically sweep the droppings into a central pit. In this case, devices of the type disclosed in the Wenger patent and of the type disclosed in this application are utilized to periodically clean that central pit.
- FIG. 1 is a perspective view of the scraper assembly showing the scraper blade in scraping position
- FIG. 2 is a perspective view of the scraper assembly showing the scraper blade in its retracted position
- FIG. 3 is a cross-sectional view taken along line IIIIII of FIG. 2;
- FIG. 4 is a schematic illustration of an oscillating scraper apparatus constructed in accordance with the teachings of this invention.
- this invention comprises a pair of spaced support frames each of which has an end panel rotatably mounted thereon. Sections of the peripheries of the end panels are generally rounded and extend below the frames as the end panels are rotated with respect thereto.
- a scraper blade is mounted between the support frames and has its ends atfixed to the end panels in such a manner that it may rotate with them. Stop means are provided on the support frames for limiting the are through which the end panels may rotate.
- the final assembly is such that when the scraper device is pulled forward the rounded peripheries of the end panels engage the bottom of the pit and swing the blade into scraping position. When the device is retracted, the rounded peripheries of the end panel cause the blade to swing upward to a nearly horizontal position and the scraper is carried solely by the rounded peripheries of the end panels.
- FIGS. 1, 2 and 3 show a pair of support frames having oppositely converging end sections 11 which are held in fixed relationship to one another by means of a stabilizing and support rod 16.
- the major sections of support frames 10 are parallel.
- a pair of scrape cables 13 and retract cables 14 are mounted on opposite ends of the support frames by suitable fastening means 15.
- the scraper blade assembly comprises a pair of end panels 21, each having a section of its periphery 22 rounded to form a runner.
- Runners 22 extend below the support frames 11 at all times as end panels 21 pivot about their respective support' frames through the permitted are.
- a scraper blade 23 is affixed between the end panels by any conventional means such as welding.
- the shape of end panels 21 corresponds generally to a quadrant of a circle having a radius greater than the distance between the bottom of the support frames and the point at which the panels are pivotally mounted thereto.
- the means for pivotally mounting end panels 21 to support frames 11 may comprise a second support rod 24 passing through apertures provided in the end panels adjacent the upper surface of the scraper blade 23.
- this construction adds stability to the entire device since the support rod 24 functions in a manner identical to stabilizing and support rod 16.
- the runners 22 preferably have flattened sections 29 affixed to their peripheries. Should the overall construction of such that the runner sections 29 tend to bind against frames 10, spacers should be inserted on rod 24 between each of the side panels and its adjacent frame.
- the weight of the scraper device is borne primarily by runners 22. Positive engagement of the scraper blade on the forward stroke is assured by the fact that runners 22 will not slide along the lower surface of the collection pit because of the relatively large amount of weight bearing on them.
- the scraper blade 23 begins engaging the droppings the scraper assembly will positively rotate into the scrape position with radial extremity 25 abutting inwardly extending lip 12.
- initial rotation of the scraper assembly is assured by the fact that the blade 23 will tend to ride up or float on the manure deposited in the collection pit.
- the device disclosed is sufliciently sturdy that an entire pit may be scraped by utilizing only one scra er device. This is, in fact, the preferable mode of operation.
- the scraper is placed into the pit and its scrape and retract cables are aflixed to suitable prime movers by means of single cables or chains in a well known manner.
- the scraper device 30 is sized relative to the pit such that the distance between the outer faces of the support frames 10 is approximately equal to the width of the pit. This spacing, as pointed out previously, is not extremely critical and sufficient allowance may be made for utilizing mass production scrapers in pits not having a precisely uniform cross section throughout their lengths.
- the pit is of suflicient depth to receive the scraper device 30 to a point approximately level with the upper edge of the support frames 10.
- the outer edges of support frames 11 will afford additional stability to the scraper mechanism as it is pulled along the trough. It will be readily apparent, however, that the depth of the pit is not particularly critical and that the concepts sets forth in this disclosure may be utilized in pits having deeper or shallower dimensions.
- the scraper blade 20 rotates about support bar 24 and engages the manure which has been deposited within the pit.
- the scraper device is moved in the F direction the entire length of the pit. Should so much manure be present within the pit that it piles above scraper blade 23 the excess will merely pass thereover to be picked up on he next oscillation.
- the device is sufficiently sturdy to p rmit this type of usage without fear of breaking it.
- the runners 22 cause scraper blade 23. to pivot clockwise as viewed in FIG. 3 and to swing upwardly and away from the manure pile into a virtually horizontal position. Once the scraper device reaches its initial starting position the cycle is repeated until all of the manure is removed from the pit into the discharge area.
- a plurality of the scraper devices 30 may be cascaded in front to back relationship within the pit at regular intervals as indicated in FIG. 4. With this arrangement the devices arev successively oscillated a distance which need be only greater than the distance between individual scraper devices 30. As the device oscillates, the manure is successively moved from scraper to scraper until such time as it reaches the discharge area. On each retract cycle the succeeding scraper is moved into scraping position to that manure which was brought forward by the preceding scraper on the last scrape cycle.
- this invention has provided a manure scraper device which, while embodying relatively simple and easily assembled components, will be effective to thoroughly clean the dropping collection pits in poultry houses or, for that matter in any type of animal enclosures where the dung is constantly or periodically deposited in collection pits.
- the device is sufficiently serviceable that it might also find use in distributing feed from one location to another or merely distributing it along the trough in such a manner that cattle or other animals may feed from each side thereof.
- a manure scraper comprising:
- scraper blade means pivotally mounted between said support frames
- rigid means positioned along said blade means and pivotable about an axis, said rigid means having a periphery with sections thereof radially spaced about said axis, said sections successively engaging the surface being scraped thereby causing rotation of said rigid means about said axis, said means being operatively connected to said blade for controlling the position of said blade means in response to the direction in which said frames are being :moved.
- said rigid means comprises panel means rotatably mounted on each of said frames, and wherein said sections on. said panel means [having peripheral sections which] are shaped to cause rotation of said [panels] panel means as they engage and are moved along said surface.
- pane l means which contacts said surface [of each of said end panels].
