The manure handling unit 1 as shown in Figs. 1 and
3, includes a holding tank 3 for receiving manure. The tank 3 has a cylindrical sidewall 5, a truncated conical top wall 7 and a truncated conical bottom wall 9. A central inlet 11, preferably circular in shape, is provided in the top wall 7, and a central outlet 13, also preferably circular in shape, is ~ provided in the bottom wall 9. A truncated, conical mouth 15 t can be fixed to the top wall 7 of the tank 3 for directing manure into the tank.
The unit 1 also includes an elbow 17, preferably a right-angle elbow, fixed to the bottom wall 9 of the tank 3 for directing manure out of the tank, through outlet 13.

sed tight a~ainst the ed~e 29 of the top wal.l 7 surrounding inlet 11, and a open position where the pl~te 27 is moved to the sicle o~ the inlet 1.~ and slig~ltly down from the iniet, The plate 27 is fixedly mounted on -two spaced-apart supports 31~ 33~ The supports 31, 33 in turn are slidably mounted at their ends on two spaced-apart guide members 35, 37. The guide members 35, 37 are located on either side o:E inlet 11 and, at one end 39, are fixed to the side wall 5 jus-t below top wall 7. At their other end 41, the guide members 35, 37 are fixed to the -top wall 7, about midway between the inlet 11 and side wall 5. The use of the outwardly and downwardly sloping top wall 7 on the tank permits the guide mem-bers to be casily yet securely fastened at their ends in position close to the inlet.
The guide members 35, 37 are slightly bent, as shown at 43 about midway between their ends 39, 41. The straight upper section 45 of the guide members 35, 37, between end`41 and bend 43 slopes down slightly from end 41. The straight lower section 47 of the guide members 35, 37, betwcen bend 43 and end 39, slopes down from bend 43 to end 39 at a slightly greater ang].e -than the angle at which the upper section 45 slopes. The sloping lower section 47 is generally paralles to the sloping top wall 7. The guide members 35, 37 are located relatively close to. the inlet opening 11 and the top wall 7. Because the upper section 45 of the guide members 35, 37 slopes down sl.ightly, relati.ve to the plane o inlet 11, the rear or trailing support 33 is slightly higher than the front or leading support 31 so as to have the closure plate 27 sit flush on the horizontal edge 29 adjacent inlet 11 when closing the inlet.
The closure plate 27 is moved along the sloping guide members 35j 37, via the support 31, 33, by suitable inlet operating means 51. The inlet operating means 51 comprises a pneuma-tic actuator 53, pivotally connected at one end 55, by a pivot pin 57, to a bracket 59 fixed to the side wall 5 just below, and centrally bet-7~
ween, the ends 39 of the gui.de me~bers 35, 37. T~e ~ther e~d 61o the actuator 53 is pi~otal~y connec-ted, by ~ pivot pin 63, to a bracket 65 on the bo-ttom of ~eading support 31 midwa~ between i-ts ends.
Operation of thc pneumatic actuator 53 will move the closure plate 27 between its inopera-tive position to the side o the inlet 11, as shown by dot-ted .lines in Fig. 4, and its operative position, jammed tight against edge 29 to close inlet 11. The angled gui.de rods 35, 37 permit -the p].ate 27 to be moved mainly in an arc-like.
motion thereby minimizing binding. The bent guide rods 35, 37, in allowing freer movement of the plate 27, also permit the actuator 53 to be attachecl to the front support member 31 thereby provi-ding a simple structure. The use of -the sloping, bent, ~uide members 35, 37 provides a very compact inlet valve means 25 located closely adjacent the top wall of the holding tank and thereby maximizing the capacity of the tank.
Outlet valve means 71 are provided in the elbow 17 for selec-tively closing the tank 3 as shown in Figs. 1 and 2. The outlet valve means 71 has a closure plate 73 mounted for sliding movement in a narrow, rectangular sleeve 75. The sleeve 75 extends between the elbow 17, and. the bottom wall 9 of the tank 3. More particu-larly, the sleeve 75 extends transversely up from the long hori-zontal arm 21 fo the elbow 17 to intersect the bottom wall 9 of the tank adjacent its side wall 5. q~he closure plate 73 is movable through the sleeve 75 betwcen a closcd position, whcre the plAte's semi-circular bottom e~ge 77 rests on the bottom of the elbow 11 thereby closing the outlet end of tank, and an open position where the plate's bottom edge 77 is within sleeve 75. When moved to : its open position, the top portion of the closure plate 73 slides up in the tank adjacent the side wall 5.
Outlet operating means 79 are provided for moving the outlet valve means 71 between its open and closed positions. These moving means 79 comprise a second p~eum~tic ~ctu~-tor 81 which is mounted within a housing 83 proiecting u~ from the top wal~ 7 oE the tank 3. The housin~ 83 is located a~jacent the side wa~l 5 of the tank 3 and is generally alicJned Wit]l the sleeve 7rj~ The housing 83 projects sli~htly into the tarlk 3, an~ s bottom end 85 is opon.
The actuator 81 is pivotally mounted at its top end 87 a bracket 89 fixed to -the top end wall 91 of housill~ 83 by a pivot pin 93. The actuator 81 has its bottom end ~5 pi~otally mounted by a pin 97 to the top end of a connecting rod 99. The connecting rod 99 is ]o mounted forsliding movement adjacent the side wall 5 of -the tank 3 by guide means 101 fixed to the side wall 5. The bottom end of the connecting rod 99 is a-ttached by a pivot pin 103 to the top edge 105 of the closure plate 73. Operation of second actuator 81 will raise or lower closure plate 73 via connecting rod 99. The projec-ting housing 83 permits the ac-tuator to be mounted within the tank well above the manure within the tank.
The unit described above is compact and self-contained. The top inlet 11 of the tank is opened or closed by means which take up littlc room Withill the tank. The inlct valve means also are protected within thc tank during shipping, installation and use of the unit. Similarly, the outlet end of the tank is also opened or closed by means which take up little room within the unit. These second valve means are also protected within the unit during its shipping, installation and use.
The unit 1 its installed within a barn 111 as shown in FIg. 6.
More particularly~ the unit 1 is installed in ground within the barn below the floor 113 or the barn The mouth 15 of the tank 3 can be flush with, or just below, the floor 113. l~he housing 83 for the actuator 81 extends above the floor 113. The free end 115 of the elbow 17 is connected to a conduit 117 buried in the ground which leads out from under the barn 111 to grQund surface 119 benea-th a manure pile 121. An air compressor unit 123 is provided within ~i'74~
the barn and is connccte~l to the unit l. ~ first line 1.25 c~rries compressed air to -the housin~ 83~ The li~e 125 is connected within the tank to the ~irst a~d second actuators 53, 81 by suitable ].ines (not shown)~ A second line 127 carries compressed air to the interior of the tank 3 via housing 83. Suitable val~es and con-trols can be provided to control the operation of the compressorunit 123 and the flow of compressed air to the actuators 53, 81 and to the tank. The raised housing 83 permits the compressed air lines to be easily connected to the unit within the barn after installation of the unit.
. In operation, manure is conveyed to the tank l by suitable means such as a conveyor 129 mounted on the floor 113 of the barn.
The manure :Ealls into the tank 3 via mouth 15 and inlet ll while the closure plate 27 is in an open position as a result of operation of ac-tuator 53. During filling of the tank 3 wi-th manure, the out-let closure plate 73 is ln its closed position, retainlng the manure within the tank and elbow 17. When the tank is substantially full, inlet closure plate 27 is closed by ac-tuator 53, outlet closure plate 73 is opened by second actuator 81, and compressed air is fed into the top of the tank 3 through line 127, and housing 83 to move the manure out of the tank, through outlet 13 and through the elbow 17 and conduit 117 to the bottom o~ the manure pile 121.
. After the tank is emptied, line 127 is closed, the outlet closure plate 53 is closed and inlet closure plate 27 is opened so that the tank can receive more manure.
sed tight a~ainst the ed~e 29 of the top wal.l 7 surrounding inlet 11, and a open position where the pl~te 27 is moved to the sicle o~ the inlet 1.~ and slig~ltly down from the iniet, The plate 27 is fixedly mounted on -two spaced-apart supports 31~ 33~ The supports 31, 33 in turn are slidably mounted at their ends on two spaced-apart guide members 35, 37. The guide members 35, 37 are located on either side o:E inlet 11 and, at one end 39, are fixed to the side wall 5 jus-t below top wall 7. At their other end 41, the guide members 35, 37 are fixed to the -top wall 7, about midway between the inlet 11 and side wall 5. The use of the outwardly and downwardly sloping top wall 7 on the tank permits the guide mem-bers to be casily yet securely fastened at their ends in position close to the inlet.
The guide members 35, 37 are slightly bent, as shown at 43 about midway between their ends 39, 41. The straight upper section 45 of the guide members 35, 37, between end`41 and bend 43 slopes down slightly from end 41. The straight lower section 47 of the guide members 35, 37, betwcen bend 43 and end 39, slopes down from bend 43 to end 39 at a slightly greater ang].e -than the angle at which the upper section 45 slopes. The sloping lower section 47 is generally paralles to the sloping top wall 7. The guide members 35, 37 are located relatively close to. the inlet opening 11 and the top wall 7. Because the upper section 45 of the guide members 35, 37 slopes down sl.ightly, relati.ve to the plane o inlet 11, the rear or trailing support 33 is slightly higher than the front or leading support 31 so as to have the closure plate 27 sit flush on the horizontal edge 29 adjacent inlet 11 when closing the inlet.
The closure plate 27 is moved along the sloping guide members 35j 37, via the support 31, 33, by suitable inlet operating means 51. The inlet operating means 51 comprises a pneuma-tic actuator 53, pivotally connected at one end 55, by a pivot pin 57, to a bracket 59 fixed to the side wall 5 just below, and centrally bet-7~
ween, the ends 39 of the gui.de me~bers 35, 37. T~e ~ther e~d 61o the actuator 53 is pi~otal~y connec-ted, by ~ pivot pin 63, to a bracket 65 on the bo-ttom of ~eading support 31 midwa~ between i-ts ends.
Operation of thc pneumatic actuator 53 will move the closure plate 27 between its inopera-tive position to the side o the inlet 11, as shown by dot-ted .lines in Fig. 4, and its operative position, jammed tight against edge 29 to close inlet 11. The angled gui.de rods 35, 37 permit -the p].ate 27 to be moved mainly in an arc-like.
motion thereby minimizing binding. The bent guide rods 35, 37, in allowing freer movement of the plate 27, also permit the actuator 53 to be attachecl to the front support member 31 thereby provi-ding a simple structure. The use of -the sloping, bent, ~uide members 35, 37 provides a very compact inlet valve means 25 located closely adjacent the top wall of the holding tank and thereby maximizing the capacity of the tank.
Outlet valve means 71 are provided in the elbow 17 for selec-tively closing the tank 3 as shown in Figs. 1 and 2. The outlet valve means 71 has a closure plate 73 mounted for sliding movement in a narrow, rectangular sleeve 75. The sleeve 75 extends between the elbow 17, and. the bottom wall 9 of the tank 3. More particu-larly, the sleeve 75 extends transversely up from the long hori-zontal arm 21 fo the elbow 17 to intersect the bottom wall 9 of the tank adjacent its side wall 5. q~he closure plate 73 is movable through the sleeve 75 betwcen a closcd position, whcre the plAte's semi-circular bottom e~ge 77 rests on the bottom of the elbow 11 thereby closing the outlet end of tank, and an open position where the plate's bottom edge 77 is within sleeve 75. When moved to : its open position, the top portion of the closure plate 73 slides up in the tank adjacent the side wall 5.
Outlet operating means 79 are provided for moving the outlet valve means 71 between its open and closed positions. These moving means 79 comprise a second p~eum~tic ~ctu~-tor 81 which is mounted within a housing 83 proiecting u~ from the top wal~ 7 oE the tank 3. The housin~ 83 is located a~jacent the side wa~l 5 of the tank 3 and is generally alicJned Wit]l the sleeve 7rj~ The housing 83 projects sli~htly into the tarlk 3, an~ s bottom end 85 is opon.
The actuator 81 is pivotally mounted at its top end 87 a bracket 89 fixed to -the top end wall 91 of housill~ 83 by a pivot pin 93. The actuator 81 has its bottom end ~5 pi~otally mounted by a pin 97 to the top end of a connecting rod 99. The connecting rod 99 is ]o mounted forsliding movement adjacent the side wall 5 of -the tank 3 by guide means 101 fixed to the side wall 5. The bottom end of the connecting rod 99 is a-ttached by a pivot pin 103 to the top edge 105 of the closure plate 73. Operation of second actuator 81 will raise or lower closure plate 73 via connecting rod 99. The projec-ting housing 83 permits the ac-tuator to be mounted within the tank well above the manure within the tank.
The unit described above is compact and self-contained. The top inlet 11 of the tank is opened or closed by means which take up littlc room Withill the tank. The inlct valve means also are protected within thc tank during shipping, installation and use of the unit. Similarly, the outlet end of the tank is also opened or closed by means which take up little room within the unit. These second valve means are also protected within the unit during its shipping, installation and use.
The unit 1 its installed within a barn 111 as shown in FIg. 6.
More particularly~ the unit 1 is installed in ground within the barn below the floor 113 or the barn The mouth 15 of the tank 3 can be flush with, or just below, the floor 113. l~he housing 83 for the actuator 81 extends above the floor 113. The free end 115 of the elbow 17 is connected to a conduit 117 buried in the ground which leads out from under the barn 111 to grQund surface 119 benea-th a manure pile 121. An air compressor unit 123 is provided within ~i'74~
the barn and is connccte~l to the unit l. ~ first line 1.25 c~rries compressed air to -the housin~ 83~ The li~e 125 is connected within the tank to the ~irst a~d second actuators 53, 81 by suitable ].ines (not shown)~ A second line 127 carries compressed air to the interior of the tank 3 via housing 83. Suitable val~es and con-trols can be provided to control the operation of the compressorunit 123 and the flow of compressed air to the actuators 53, 81 and to the tank. The raised housing 83 permits the compressed air lines to be easily connected to the unit within the barn after installation of the unit.
. In operation, manure is conveyed to the tank l by suitable means such as a conveyor 129 mounted on the floor 113 of the barn.
The manure :Ealls into the tank 3 via mouth 15 and inlet ll while the closure plate 27 is in an open position as a result of operation of ac-tuator 53. During filling of the tank 3 wi-th manure, the out-let closure plate 73 is ln its closed position, retainlng the manure within the tank and elbow 17. When the tank is substantially full, inlet closure plate 27 is closed by ac-tuator 53, outlet closure plate 73 is opened by second actuator 81, and compressed air is fed into the top of the tank 3 through line 127, and housing 83 to move the manure out of the tank, through outlet 13 and through the elbow 17 and conduit 117 to the bottom o~ the manure pile 121.
. After the tank is emptied, line 127 is closed, the outlet closure plate 53 is closed and inlet closure plate 27 is opened so that the tank can receive more manure.
