Description

1 This application is a division of app:Lication serial number 374,228 filea March 30, 19~1.
BACKGR~VND OF THE INVENTION
The invention relates generally to a novel manure spreader, more particularly, is directed to a manure spreader including both a slow speed impeller and a high speed spinner positioned to receive a flow of manure from the impeller and to spray the manure outwardly in a desired spray pattern.
Many types of spreaders have been developed by prior workers in the field which are usually employed in and about farms to utilize the fertilizer value of manure from herds of farm animals, for example,dairy cattle, in an efficient and economical manner. ~he prior art manure spreaders have included flail type spreaders which are generally most commonly employed for use with solid manures. Other workers in the art have developed spray type spreaders which employ necessary tanks, hoses and accessory equipment to effectively distribute liquid manures. Such wet type manures usually must first be processed to add sufficient water to permit use with the spray equipment. Both flail type spreaders and spray type spreaders have been generally and widely utilized in the past and both type types are quite common. However, certain operating difficulties and inefficiencies have arisen with the presently available spreading equipment due to the nature of the manures available for distribution. For example, spreaders designed for solid application, such as the flail 'cype spreader, cannot readily be employed for use with liquid manures. Such types are particularly designed for use with solid manures and because of this, have limited storage capacity during periods of application. Also, because of the load characteristics 1 inherent when spreading solid type manures, the prior art type of flail type spreader had to be ruggedly constructed and all parts had to be designed of increased strength to handle the solid materials. Despite the increased structural strength capabilities built into the equipment, there has been evidence of considerable wear and breakage, such as bearing wear, chain breakage and mechanical damage to the operating parts due to the nature of the solid manures.
In the case of prior art liquid type spreaders, the presently available prior art types incorporate a tank-like vehicle which is ~uitable only for use in the application of liquid manures. Accordingly, such spray type spreaders were suitable for use only with waste materials that haa previously been pretreated prior to introduction into the tank of the spreader vehicle in order to provide an effluent specifically designed for use with the specific spreader.
SUMMARY OF THE INVENTION
The present invention relates generally to a liquid and semi-liquid type manure spreader, and more particularly, is directed to a manure spreader incorporating a V-shaped body for holding the manure, an impeller having a plurality of planar sides and blades positioned near the bottom of the body to direct the manure, an outlet gate in a side of the body and a high speed spinner receiving the effluent from the gate for spray distribution as the spreader is propelled.
The manure spreader of the present invention includes a wheeled,open tank into the top of which liquid and/or semi-liquid manures can be easily fed by using existing, readily available loading equipment. The body of the spreader is generally V-shaped in cross-sectional configuration and ~ 1 67078 1 incorporates near the bottom thereof a heavy duty, chopper-type auger or impeller. The impeller includes an elongated body including planar sides and a plurality of separate blades angularly outwardly projecting from the sides. The impeller is longitudinally positioned near the apex of the V-shape of the body and has its blades positioned generally in the con-figuration of a helix, a rear portion of which helix is designed to propel manure from the rear of the tank to a medially positioned manure exit gate and a front portion of which helix is designed to propel manure from the front of the body toward the medially positioned gate.
A high speed spinner is affixed in rotary engagement exteriorly of the spreader body in position to receive the effluent from the gate and to direct the effluent in a spray pattern over the field to be so treated. Preferably the spinner rotates at a rotative speed that is from ten to fifteen times the rotational speed of the impeller whereby both devices are rotated in unison, in opposite directions and at proportional rates of speed. A hinged deflector can be ~ employed in conjunction with the spinner in the path of the effluent from the spinner to vary the spray pattern to suit the existing field conditions.
In the preferred embodiment, the spinner is provided with a plurality of angularly offset buckets or scoops whereby only a portion of the buckets will be in the same relative angular contact with manure at any given instance. In this manner, the staggering of the scoop angular orientation results in a device that is capable of operation at greatly reduced horsepower requirements. The spinner scoops are preferably forwardly curved to provide a better manure throwing pattern.

DESCRIPTI ~ OF THE PREFEP~RED EMBODIME TS OE' THE INVENTION
Although specific terms are used in the following description for the sake of clarity, these terms are intended to refer only to the particular structure of the invention selected for illustration in the drawings, and are not intended to define or limit the scope of the invention.
Referring now to the drawings, there is shown in Figs.
1-3 a manure spreader generally designated 10 which comprises essen-tially a wheeled, tank type body 12 having an open top 14 into which the manure (not shown) to spread can be readily dumped. The tank 12 is generally V-shaped in configuration and is carried upon a suitable, sturdy chassis 36 in a con-ventional manner. The chassis 36 is arranged for easy transport over the field to be treated by employing a plurality of right and left wheels 32, 34 mounted in pairs upon conventional axles 38 in well known manner.
The manure spreader 10 is conventionally transported and powered by a tractor or other farm equipment (not shown) in well known manner. For example, a hitch ~2 is illustrated in Fig. 1 for usual towing connection to the picce of farm equipment. Power for operation of the device is also con-ventionally drawn from the tractor or other farm equipment through a rotating drive shaft 44 which is supplied with a suitable coupling 45 for connection to the tractor PTO (not shown) in usual manner.

1 As best seen in Figs. 2 an~ 3, an impeller 128 is longitudinally positioned within the interior of the body 12 near the bottom of the V-configuration. The impeller 12 extends the entire len~th of the tank body 12 and forwardly has its shaft 130 coupled to the drive shaft 44 in known manner whereby rotation of the drive shaft 44 by the tractor (not shown) will cause corresponding rotation of the impeller 128.
The impeller shaft 130 is ~ournalled within conventional farward and rearward bearings 20 for rotation relative to the tank or body 12. The impeller shaft 130 ex~ends forwardly in a shaft extension 19 for powering the manure spreader system as hereinafter more fully set forth.
Referring now to Figs. 2 and 6, it will be observed that the auger or impeller 128 includes an elongated body l32 having planar sides 136, 138, 140, 142 which are secured to the impeller shaft 130 in conventional, sturdy manner, such as by welding or other interconnection. A plurality of individual planar ~lades 134 are defined one from another and are welded or otherwise secured to the impeller body 132 in the general configuration of a helix for manure directing purposes. The helix is divided into a rearwardly directed helix 24 which acts to urge manure (not shown) contained within the tank 12 rear-wardly within the body from the front wall 31 to the side outlet 48 and a longitudinally juxtaposed forwardly directed helix 26 which serves to urge the manure forwardly within the tank 12 from the rear wall 30 toward the side opening 48. The rearwardly directed helix 24 terminates rearwardly adjacent to the side opening 48. An unloading section 28 is defined at the interface between the rearward helix 24 and the forward helix 26 to efficiently direct the manure (not shown) through 1 1 6707~

1 the side openin~ o.r gate 48. As il.lustrated, the forwardly directed helix 26 term.inates forwardly adjacent to the side opening 48 at the unloading section 28. Accordingly, upon impeller rotation, the dual directed helices 24 and 26 tend to urge the liquid and semi-liquid manure contained within the tank 12, both from the front wall 31 and from the rear wall 30 toward the unloading opening 48. As illustrated, the unloading opening 48 is positioned closer to the tank body front wall 31 and further from the tank body rear wall 30.
One of the tank body inclined sidewalls 46 or 47 is provided with the side opening or gate 48 to permit the manure ~not shown) contained within the tank body 12 and driven by the impeller 128 to exit therethrough for manure spreading purposes. The gate or opening 48 transversely aligns with the unloading section 28, for side unloading to the spinner 154.
It is noteworthy that the unloading section 38 comprises the interface between the rearwardly directing helix 24 and the forwardly directing helix 26 which serves to urge or sweep the manure transversely through the opening 48 as the impeller 128 is rotated upon the application of rotative forces to the drive shaft 44.
Referring now to Figs. 1 and 3, a spreader chamber 50 is welded or otherwise secured exteriorly to a tank sidewall 46 or 47 and comprises generally a right wall 52, a left wall 53 and an interconnecting floor or base wall 56. The manure spreading spinner 154 is mounted for rotation between the right and left spreader chamber walls 52, 53 and can have its shaft 160 journalled within respective front and rear bearings 62 in a conventional manner. As illustrated in Fig. 3, the spreader chamber floor 56 forms a continuation of the spreader body inclined wall 47 so that the manure delivered to the opening 48 1 through the in-te~actiorl of the re.~rwclrdly clirected helix 2~, the forwardly directed helix 26 and the unloading section 28 dumps or flows the manure directly from within the tank 12 into the spreader chamber 50 for throwing or spreading by the spinner 154 as the spinner is rotated a-t high rotative speeds.
If desired, a door, (not shown) can be provided in known manner to close the opening 48 in the body wall 46 when the device 10 is not in use and to expose the opening 48 when it is desired to employ the spreader 10 for manure spreading purposes.
As above set forth, the spinner shaft 160 is journalled between the right and left bearings 62 and is positioned to receive and to propel the manure ~not illustrated) which is driven into the spreader chamber 50 upon rotation of the impeller 120. It is a feature of this invention to rotate the spinner 154 many times faster than the speed of rotation of the auger or impeller 128. By driving the auger at a relatively slow rate of speed, the manure loaded within the interior of the tank 12 can be most advantageously directed to the oepning or gate 48 without the stranding of solids upon the inclined body sidewalls 46, 47. The high speed rotation of the spinner 156 provides maximum efficiency in spreading or throwing the manure.
Additionally, the construction comprising the opening or gate 48 combined with the slow speed of rotation of the impeller or auger 128 facilitates the handling of drier materials without stranding of the solids within the body prior to spilling into the spreader chamber 50.
Due to this capability of handling a full range of materials from very wet to very dry, the manure spreader 10 of the present invention can be employed to handle a wider variety of materials to be spread in a troublefree and highly efficient g _ ~ 1 67078 1 manner. The individual auger blades 134 are preferably formed of planar steel sheet of sufficient thickness for the operation to provide adequate strength. The blades 134 extend in width the entire width of their associated auger sides 136, 138, 140, 142 and, as best seen schematically in Fig. 7, are positioned in dual, opposite helical arrangement. Additionally, as illustrated, the blades 134 are endwardly curved and extend near the bottom of the tank upon rotation for a better and more efficient manure movement forwardly and rearwardly through the tank 12.
Referring now to Fig. 1, one embodiment of a spinner drive mechanism will now be described. As illustrated, the auger shaft 130 extends through the front bearing 20 in a conventional shaft extension 19 to which is spinned or otherwise secured a ~irst gear drive system 82. Accordingly, when the drive shaft 44 is connected to the tractor PT0 (not shown) through the coupling 45, rotation of the drive shaft 44 causes simultaneous rotation of the impeller shaft 130 and the shaft extension 19. As above set forth, it is preferable to rotate the impeller shaft 130 at a relatively slow speed and the spinner shaft 156 at a relatively high speed. The power sprocket 84 drives a driven sprocket 86 through a conventional drive chain 98. The driven sprocket 86 in turn powers the second gear drive system 88 to thereby cause higher speed rotation of the shaft 156 through the coupling 90.
The drive system described is illustrative only, and it is contemplated that other gear systems or other mechanical drives can be employed to transmit rotative power from the tractor PTO (not illustrated) to rotate simultaneously the auger 128 and the spinner 154. See for example the gear drive 1 train illustrated in my co-pending Canaaian paten-t application Serial No. 374,224, filed March 30, 1981.
Preferably, the auger or impeller 128 is rotated by the drive shaft 44 at a rotative speed of approxima-tely fifty revolutions per minute. Simultaneously, through the Eirst and second gear drive systems 82, 88, above enumerated, the spinner 154 is optimumly rotated at a speed of from approximately five hundred and forty revolutions per minute to seven hundred and fifty revolutions per minute to provide an optimum spray pattern.
As illustrated in Figs. 1, 2 and 3, in order to easily vary the spreader pattern, the spreader chamber 50 may be provided with an overhead deflector 70 which can be arranged for vertical or hinged adjustment relative to the spreader 154 in well known manner. In the embodiment illustrated, a hydraulic cylinder 72 is supported in pivotal manner from the body 12 through a stationary bracket 80 in a manner to reciprocally move the deflector 70 relative to the spinner 154. As best seen in Fig. 3, the cylinder 72 functions its piston rod 74 in the directions indicated by the arrow 76 to move the deflector 70 between the positions illustrated in full lines and phanton lines. In one embodiment, as illustrated, the deflector 70 may be provided with suitable guides 78 to facilitate the inclined, vertical movement indicated. If desired, the cylinder 72, the piston arm 74 and the deflector 70 could also be arranged to pivot the deflector relative to the spinner 154. As above set forth, the purpose of the deflector 70 is to vary the spray pattern, and this variation may be accomplished in any suitable, efficient manner.
As best seen in Fig. 3 the shaft 130 of the auger 128 rotatively carries an enclosing, elongated, rectangular or 1 1 6~07g 1 s~uare cross section body 132 which can be secured to the impeller shaft 128 in conventional, sturdy manner, such as welding or other suitable strong, known type of interconnection.
A plurality of individual blades 134 are welded or otherwise secured to the straight sides 136, 138, 140 and 142 which define the impeller body 132. The blades 134 are arranged about the body 132 in the configuration of helices 24, 26 to direct or push the manure (not shown) through the body 12 to the gate or opening 48 and thence to the spinner 154 for spreading purposes. As illustrated, each blade 134 preferably extends in length the entire thickness or width of its corresponding side 136, 138, 140 or 142. Each blade 134 is generally rectangular in configuration and terminates outwardly in a rounded edge 44 to efficiently conform to the bottom configuration of the spreader tank 12. The rounded edges provide an efficient shape for positive cleanout as the shaft is rotated.
Preferably, the blades 134 tilt rearwardly at an angle of approximately five degrees to ten degrees from the normal to the axis of the shaft 128 to reduce friction and torque load.
See Fig. 6. Additionally, the five to ten degree angularity of the blades aids in moving dry materials through the body by slowing down the progress of such materials.
The square corners 146, 148, 150, 152 defined by the straight, angularly interconnected body sides, 136, 138, 140 142 create a pulsating or agitating action in the manure (not illustrated) when the shaft 130 is rotated to aid in breaking up large particles and in directing the manure toward the spinner 154. Additionally, the agitation of the manure caused by the repeated impacts of the impeller body corners 146, 148, 150, 152 together with the chopping action of the individual ~ 12 -1 blades acts to d:iscourage the manu~e Erorn bridging over the impeller 128 to preven-t interference with the movement of the manure within the body 12 toward the spinner 154. The cutting ~ction of the individual blades 134 combi~es with the pulsating action created by the rotation of the body corners 146, 148, 150, 152 to pulsate or vibrate the material. The combined actions of the blades 134 and the body 132 as the shaft is rotated aids in transportation of the manure through the body and thus accommodates a great variety of materials from tO substantially semi-solid to substantially liquid compositions.
Referring now to Figs. 4 and 5, one embodiment of a spinner 154 is illustrated comprising generally a shaft 156 which is suitably journalled within bearings 62 which are mounted within the spreader chamber walls 52, 53 for high speed rotation within a spreader chamber 50. Inasmuch as it is contemplated that a suitable gear train drive to rotate the spinner 154 can be developed in known manner similar to the drive previously shown and described in Fig. 1, the drive need not be further described at this time. Suffice it to say that it is desirable to rotate the spinner 154 at a considerably greater speed than the impeller, 128, and any suitable known type of drive that will accomplish this result that could be efficiently employed would be satisfactory for the purpose.
The spreader or spinner 154 comprises a plurality of individual, angular scoops or buckets 158 each of which is defined by a radially oriented roof 160, a radially oriented floor, 162, a left side 164 and a right side 166. Preferably, the respective roofs 160 and floors 162 of the individual scoops 158 are curved in the direction of rotation to aid in the manure throwing or spreading function. As illustrated, each scoop or bucket 158 defines an arc of ninety degrees whereby ~our angularly contiguous scoops 1~8 can ~e positio~ed about the spinner shaft 156. In a preferred embodiment, as best seen in Fig. 5, a plurality of four separators 168, 170, 172, 174 are employea to define ~ou~ conti~uous, circularly arranged scoops 158. As illustrated, each of the separators 168, 170, 172, 174 serves both as the roof 160 of one scoop and as the floor 162 of the next circularly adjacent scoop.
Referring still to Figs. 4 and 5, it will be seen that ~0 the spinner 154 comprises a plurality of three juxtaposed scoop sections 176, 178, 180 each of which includes a plurality of four circularly adjacent scoops or buckets 158. It is note-worthy that the scoops 158 of the scoop section 176 are circu-larly angularly offset from the scoops 158 of the scoop section 178 by an angle of thirty degrees. Similarly, the scoops 158 of the scoop section 180 are circularly angularly offset from the scoops 158 of the scoop section 178 by an angle of thirty degrees to thereby provide a balanced design and to prevent undue ~ibration upon high speed rotation of the spinner. The staggered arrangement of the scoops 158 in the various scoop sections surprisingly results in considerably reduced horsepower requirements necessary to rotatively drive the spinner 154 during the manure spreading operations. The curvilinear design of the individual scoops or buckets 158 coupled with the high speed rotation of the spinner acts to trap a cushion of air about the shaft 156 whereby the material to be spread rides centri-fically outwardly in the scoops, a phenomenon that also appears to reduce the quantity of energy required to rotate the spreader 154.
As best seen in Fig. 4, a sturdy, steel, ~eplaceable chopping strip 182 is removably affixed at the respective ends `` 1 1 67078 t of the separators 168, 170, 172, 17~ to aid in choppiny solid manure particles as the manure is urged toward the spinner 154 by the rotative action ~f the impeller 128. Preferably, teeth 184 are formed in the chopping strip edge to enhance the chopping action while the spinner is rotated at high speed.
Due to the considerable wear occasioned by repeated impacts of the chopping strips 182 against the manure, the chopping strips are preferably removably connected by bolts 186 which position through aligned openings in the respective chopping strips 182 and the separat~rs 168, 170, 172 and 174. Additionally, to increase the useful life of a chopping strip 182, a second row of teeth 788 preferably can be formed at ~he second longitudinal edge. Accordingly, when the first row of teeth 184 in a chopping strip demonstrate sufficient wear, then the second row of teeth 188 can be readily brought into use by simply removing the connection bolts 186, reversing the chopping strip and then reconnecting with the second row of teeth positioned radially outwardly.
~lthough the invention has been described with a certain degree of particularity, it is understood that the present disclosure has been made only by way of example and that numerous changes in the details of construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention.
