BY Q

Patented Apr. 13, 1954 UNITED STATES PATENT OFFICE RECIPROCATING HOE TYPE MANURE CONVEYER My invention relates to improvements in reciprocating hoe type conveyors for evacuating manure from the manure gutters of cow barns and the like.

The primary object of my invention is to provide a simply constructed, hoe type conveyor for cleaning out such manure gutters and which is adapted to be slidably fitted in the gutter for efficient operation without requiring alteration in the gutter, or additional structure therein for slidably guiding the conveyor, and which is constructed and arranged for installation in the gutter by merely disposing the same therein, and requires no fastening means.

Another object is to provide a conveyor of the type and for the purpose above set forth equipped with an automatically controlled hydraulic pressure drive of simple, inexpensive construction which is easy to install.

Other and subordinate objects, within the purview of my invention, together with the precise nature of my improvements will be readily understood when the succeeding description and claims are read with reference to the drawings accompanying and forming part of this specification.

Figure 10 is a fragmentary view in longitudinal vertical section taken on the line I 0-40 of Figure 9 and illustrating how one of the series of hoe 5 Claims. (Cl. 198-224) 2 blades propels the manure into the disposal gutter; and

Figure 11 is a similar view illustrating how the other series of hoe blades propels the manure into the disposal gutter.

Referring by numerals to the embodiments of the invention illustrated in the drawings, and first to the preferred embodiment illustrated in Figures 1 to 3, the numeral l designates a cow barn, shown fragmentarily as sufficient for the present purposes, 2 the floor of the barn, 3 the usual manure gutter in the floor 2 in the rear of the cow stalls 4 and having a flat bottom 5 and perpendicular sides 6, and I one side of the barn I.

The conveyor of my invention, in the preferred embodiment, comprises an elongated hoe unit i0 adapted to be reciprocated endwise in the gutter 3 for advance and retraction and which is sufficiently longer than the gutter 3 to extend at a front end ll thereof, when retracted, out of an open end l2 of the gutter 3 at the side 1 of the barn I.

The hoe unit l0 comprises a pair of opposite, laterally spaced, metal side bars 13 of the same width as the depth of the gutter 3 and preferably hollow with inner sides converging downwardly, relatively, for a purpose presently seen. The side bars [3 are spaced apart, by means presently described, to slidably engage flatly the sides 6 of the gutter 3 with the bottom longitudinal edges of said bars sliding on the bottom 5 of said gutter. Preferably, the side bars [3 are formed in sections I5 connected together by means of an end tongue IE on each section fitting in the end of an adjoining section and fastened therein by a cross bolt I1.

Rock shafts [8 with reduced ends I?! journaled in upper edge bosses 20 on the side bars l9 space said side bars l3 apart. Hoe blades 2| depend from the rock shafts l8 transversely of the gutter 3 and are fixed to said rock shafts for swinging longitudinally of the gutter 3. Each hoe blade 2| is formed with a longitudinal upperedge sleeve 22fitted on the rock shaft l8 and a set bolt 23 in the sleeve 22 engages the rock shaft is and provides for adiustably connecting the hoe blade 2| to its rock shaft I8. As best seen in Figure 1 the rock shafts [8 space the hoe blades 2| apart longitudinally of the gutter 3 the same distance as the width of the stalls 4, for a purpose presently seen. As best shown in Figures 2, 3 and 5, the hoe blades fit with a working clearance between the side bars [3 and incline downwardly from the rock shafts l8 into the gutter 3 forwardly of the unit II], that is in the direction of advance movement of said unit. The lower edges of said blades 2| slidably engaging the bottom 5 of the gutter 3. Stop lugs on the side bars l3 in the rear of the hoe blades 2! prevent rearward swinging of said blades out of the described inclined position. Preferably, the hoe blades 2| are inclined from the vertical approximately 10.

A power drive for reciprocating the hoe unit H3 is provided which preferably comprises the following. An electric motor 28, adapted to be connected to any suitable source of power, not shown, is fixed on a shelf 29 on the side i of the barn I outside said barn. The armature shaft 30 of the motor 2% is operatively connected at one end to a suitable pump ti on said shelf 29. A fluid supply tank 32 supported on the side i of the barn l by a bracket 33 is connected to the suction side of the pump Si by a pipe line 3 3. A pitman 35 including a disk 36 fastened on the other side of the armature shaft is and enclosed in a housing 3%! operatively connects said shaft to oscillating core it of a valve 3'i'for controlling a fluid pressure circuit presently described. The valve controls, in a manner presently described, admission and discharge of fluid pressure to opposite'ends of a fluid pressure cylinder to extending longitudinally above the extending end ii of the hoeunit it with one end pivoted, as at ii, between bearing brackets 42 on the side l of the barn 5 outside said barn, and so that said cylinder is vertically swingable for convenience in installing the same. A piston "e3 extending out of the other end of said cylinder is is operatively connected to the front end it of the hoe unit it! by a cross rod is on said piston rod pivoted in a pair of bearing ears 45 upstanding from the side bars 53.

Describing new the details of the fluid pressure circuit and the means whereby the valve 3? controls the same, a fluid pressure and return line 46 extends from one end of the cylinder at to one side of the valve 3i, and a return line M from said side of the valve to the supply tank 32. A fluid pressure and return line 33 extends from the other end of said cylinder iii to the other side of the valve 3'5 and a fluid pressure line 49 from the pressure side of the pump to said other side of said valve The valve core 36 is provlded with a pair of opposite, arcuate ports 5i], 5i

full and dotted lines in Figure 8, and whereby,

as will be seen, the piston 43 is reciprocated to advance and retract the hoe unit it.

A pair of horizontal channel iron guides 54 support the bottom edges of the side bars 13, outside the side i of the barn i with inner ends bolted, as at 55, to said side ll. Diagonal brace rods 56 extend from the guides 54 to said side 1 of the barn to prevent said guides 5 from sagging.

Referring now to the operation of the preferred embodiment of my invention, in the fully retracted position of the hoe unit it, as shown in Figure l, the hoe blades ii are disposed at opposite sides of the stalls i with said blades swung downwardly, under the influence of gravity, into propelling position in which the sameengage the bottom 5 of the gutter 3. Upon reciprocation of the hoe unit I0, by the described drive, the hoe blades 2!, upon advance of said unit iii, scrape and propel manure 51, by stages, forwardly in the gutter 3 into piles, whereas, upon retraction of said unit iii, the hoe blades 2i swing upwardly, forwardly, and wipe rearwardly over the piles to swing downwardly behind the same for repeat operation to scrape and propel forwardly. As will be seen, the stroke of the hoe unit it is greater than the distance between hoe blades 2! so that each blade 2! will propel a pile of manure forwardly during the forward stroke of the unit iii for a preceding blade 2! to pick the pile up during the next forward stroke of said unit. the manure will be propelled by stages out of the open end i2 of the gutter 3, outside the barn I, to be disposed of, as desired, for instance by a conveyor, not shown.

In the modified embodiment illustrated in Figures 9 to 11, a hoe unit 68, like the unit 50, with exceptions presently noted, is provided to reciprocate in a manure gutter 8| extending behind two aligned rows 62?, E3 of stalls, said unit i0 extending across a, disposal gutter 54 between the rows 62, E3 of stalls and below the level of the gutter ti for receiving the manure from the gutter ill to be removed from the disposal gutter in any desired manner. The drive for reciprocating the hoe unit iii), and designated as a unit by the numeral its, is the same as that previously described with the exception that said drive 456 is located inside the barn 61, the cylinder 58 thereof extending outwardly of one end of the hoe unit 58 and the channel iron guides 54 of the preferred embodiment, together with i l2 and propel the piles into the disposal gutter 65 by stages. For this purpose, the series to, H of hoe blades inclined downwardly into the gutter 5i oppositely in each series with respect to the other series, the series it inclining downwardly in the direction of retracting movement of the hoe unit till, and the series 7i inclining downwardly in the direction of advancing movement of said unit.

The foregoing will, it is believed, suffice, to

impart a clear understanding of my invention without further explanation.

Manifestly, the invention, as described, is susceptible of modification, without departing from the inventive concept, and right is herein reserved to such modifications as fall within the scope of the appended claims.

Having described my invention, what I claim as new is:
