hley, Jr., Billings, Mont., assignors to Farmhand, Inc.,

South Hopkins, Minn., a corporation of Delaware Filed Nov. 25, 1966, Ser. No. 597,065 Int. Cl. B02c 13/06 U.S. Cl. 241186 Claims ABSTRACT OF THE DISCLOSURE In the grinding of fibrous material, such as hay, in a hammermill, the hay is usually fed to the mill in slabs or cakes peeled from a hay bale. The slabs or cakes are delibered in succession to the rotating hammers of the mill by the feeding rotor overlying and engaging each slab as it moves in the downwardly sloping throat of the mill. Heretofore, when the trailing end of the slab or cake was moved beyond contact with the feeding rotor, the loose trailing end or slug would gravitate into the path of the rotating hammers and be struck thereby with a heavy impact, imparting a shock load to the hammermill structure and effectively shortening the life of the components thereof, such as the hammer elements, screen, shaft bearings and the like. Hence, the primary object of this invention is the provision of a device for hammermills which will effectively support a slab or cake relative to the rotating hammers in such manner that the slab is cut into by the hammers uniformly until the entire slab is ground, whereby to prevent slugging.

Another object of this invention is the provision of an attachment or device as set forth, which provides a plurality of generally parallel guide channels for delivery of granular material to the grinding chamber of the hammermill.

Yet another object of this invention is the provision of a hammermill including a housing having an inlet for delivery of material to the grinding chamber thereof, the throat having an inwardly and downwardly sloping bottom wall portion provided with a plurality of upstanding parallel guide plates for said material. The above, and still further highly important objects and advantages of this invention will become apparent from the following detailed specification, appended claims and attached drawings. Referring to the drawings, which illustrate the in vention, and in which like reference characters indicate like parts throughout the several views:

FIG. 1 is a view in perspective of a hammermill incorporating the device of this invention;

FIG. 2 is an enlarged fragmentary transverse section, taken substantially on the line 2-2 of FIG. 1;

FIG. 3 is a fragmentary view in section, taken on the line 3-3 of FIG. 2;

FIG. 4 is a fragmentary view partly in side elevation and partly in section, taken on the irregular line 44 of FIG. 3; and

FIG. 5 is a view in perspective of the feed control device of this invention.

A conventional hammermill is shown in the drawings ice as comprising a housing 1 defining an inlet throat 2, a grinding chamber 3 and an outlet opening 4, a rotary grinding head 5 journalled in the grinding chamber 3 on a generally horizontal axis, a material feeding rotor 6 extending transversely of the throat 2 and journalled on an axis generally parallel to the axis of rotation of the grinding head 5, a semi-cylindrical screen 7, and a discharge screw conveyor or auger 8.

The housing 1 comprises a pair of laterally spaced generally vertical side walls 9 and 10, a top wall 11, a bottom wall comprising a pair of cooperating bottom wall sections 12 and 13, a rear wall 14 and a front wall or skirt 15. A portion of the top wall 11, side walls 9 and 10, and bottom wall section 12, cooperate to define the inlet throat 2, and an open-topped feeding tray 16 is riveted or otherwise rigidly secured to the side walls 9 and 10 and bottom wall section 12 at the inlet end of the inlet throat 2. The bottom wall sections 12 and 13 slope downwardly and rearwardly from the skirt 15, the bottom wall section 13 providing a trough portion 17 in which the auger 8 is disposed. The screen 7 is held in place concentric to the grinding head 5 by a pair of flanges 18 and clamping brackets 19, one of each of which is shown in FIG. 2, and by inturned flanges 20 on an access door 21 that is hinged at its opposite sides to the sidewalls 9 and 10, as indicated at 22. The access door 21 is releasably locked in closed position by a screw latch mechanism 23.

The grinding head 5 is of conventional design, involving a plurality of axially spaced generally rectangular plates 24, one of which is shown, keyed or otherwise rigidly secured to a central shaft 25 and having a plurality of circumferentially spaced rods 26 extending in a direction axially therethrough. A plurality of rectangular grinding hammers 27 are journalled on the rods 26 between different ones of the plates 24 for swinging movements between inoperative depending positions shown by full lines in FIG. 2, and operative radially outwardly projecting positions shown by dotted lines in FIG. 2, the hammers 27 assuming their radially projecting operative positions responsive to rotation of the grinding head 5. The shaft 25 is journalled in bearings 28, one of which is shown in FIG. I, mounted on the side walls 9 and 10, and is driven by suitable means not shown. The auger 8 is pinned or otherwise rigidly mounted on an auger shaft 29 that is journalled in bearings 30, one of which is shown in FIG. 1 secured to the sidewall 9, the auger 8 delivering ground material outwardly through the discharge opening 4. The auger shaft 29 is rotated by suitable means, not shown.

The feeding rotor 6 comprises a pair of end flanges 31 anda 32 connected by a drum 33 having circumferentially spaced radially outwardly projecting toothed ribs 34 that extend axially between the end flanges 31 and 32. The rotor 6 is mounted on an axial shaft 35 that extends axially outwardly beyond the end flanges 31 and 32 and through a pair of arcuate slots 36 in the housing sidewalls 9 and 10. Opposite end portions of the shaft 35 are journalled in bearings 37 secured to the outer ends of a pair of mounting arms 38 that are pivotally secured to respective ones of the housing sidewalls 9 and 10 by pivot pins or the like 39. The arms 38 are connected by an inverted generally U-shaped frame 40 which straddles the upper portion of the housing 1 and which includes depending leg portion 41 each pivotally connected at its lower end to the adjacent arm 38 by a nut equipped bolt or the like 41a.

The slots 36 and pivotal connections 39 of the arms 38 permit the feeding rotor 6 to move upwardly and downwardly within the inlet throat 2, whereby the feeding rotor 6 may ride upon, and control feeding movement of, material to the grinding chamber 3. Such bodily movement of the rotor 6 is controlled in part by a pair of disks 42 that are eccentrically mounted on a transverse shaft 43 adjacent respective ones of the side walls 9 and 10, the shaft 43 being journalled in suitable bearings in the sidewalls 9 and 10. The shaft 43 extends axially through a pair of slots 44 in the legs 41 and terminates at one end in an angularly displaced handle 45 by means of which the shaft 43 and disks 42 may be rotated. The disks 42 are provided with aligned circumferentially spaced openings 46 for reception of a stop bar 47 which rests upon the top wall 11 in one selected position of the disks 42 to permit maximum upward and downward bodily movement of the feeding rotor 6. By inserting the stop bar 47 through a selected pair of aligned openings 46 and through the slots 44, bodily upward and downward movement of the feeding rotor 6 may be limited as desired. Further, the legs 41 are provided with aligned openings 48 which, when the stop bar 47 is inserted therethrough and through a given pair of aligned openings 46, holds the rotor 6 against upward and downward movement in the inlet throat 2. Further, downward movement of the feeding rotor 6 is limited by engagement of the disks 42 with a pair of rollers 49 journalled in the upper end portions of the legs 41.

Feeding rotation is imparted to the feeding rotor 6 from a shaft 50 journalled in suitable bearings in the side walls 9 and 10 and connected to a source of power, not shown, through speed reduction gearing including a drive chain 51 entrained over a sprocket Wheel 52 fast on the shaft 50 and a second sprocket whel 53 journalled on the pin or shaft 39 projecting laterally outwardly from the adjacent side wall 9. A second endless chain 54 is entrained over a sprocket wheel 55 journalled on the adjacent pin or shaft 39 for common rotation with the sprocket wheel 53, and another sprocket wheel 56 mounted fast on the adjacent end of the feeding rotor shaft 35, see particularly FIGS. 1 and 3. A supporting bracket 57 rigidly secured to the adjacent wall 9 of the housing 1, supports the outer end portion of the adjacent shaft or pin 39.

The feed control device of this invention comprises a generally rectangular base plate 58 bent intermediate its inner and outer ends 59 and 60 respectively to form inner and outer plate portions 61 and 62 respectively, and a plurality of laterally spaced parallel rigid guide plates 63 projecting upwardly from the base plate portion 61. As shown in FIGS. 1, 2 and 5, the guide plates 63 eX- tend from the inner end 59 toward the outer end 60, portions of the guide plates 63 overlying a part of the outer base plate portion 62. A pair of mounting brackets 64 are provided with slots 65 for the reception of nut-equipped mounting screws 66 that extend through suitable apertures in the side walls 9 and 10 within the throat 6. Further, the base plate portion 62, adjacent the outer end 60 thereof, is provided with a slot 67 for reception of a nut-equipped screw 68 that extends through a suitable opening in the bottom wall portion 12 at the outer end portion of the throat 2.

In the normal use of a hammermill of the type illustrated for chopping or grinding baled hay, without the use of the device of this invention, a slab or cake of baled hay, indicated at X in FIGS. 2 and 3, is moved downwardly and inwardly on the infeed portion 12a of the bottom wall section 12, and is delivered to the path of circular travel of the hammer elements 27 by the feeding rotor 6. With the bale slab X disposed on the portion 12a, the slab is directed generally toward the bottom portion of the grinding head, and becomes disengaged from the feeding rotor 6 while yet of fairly large size. When thus disengaged from the feeding rotor 6, this remaining portion or slug falls or is drawn into the path of the hammers 27 by the hammers themselves, the hammers 27 striking the slug with a heavy impact which not only interferes with eflicient grinding of the slug material, but also places the entire hammermill under a severe shock 4 load. Moreover, the impact of the slug against the screen 7 is apt to deform or otherwise injure the screen 7, necessitating frequent replacement thereof.

With the feed control device of this invention installed in the infeed throat 2, as shown in FIGS. 1-3, the base plate 58 rests upon the bottom wall portion 12a, the guide plates 63 underlying the feeding rotor 6, the top edges of the guide plates 63 being disposed in a plane which intersects the rotary grinding head 5 upwardly of the bottom portion thereof. Thus, when the slab X of hay is fed into the inlet throat 2, and moved toward the grinding head 5 by the feeding rotor 6, the slab X rides on the top edges of the guide plates 63, and is disposed substantially on a level with the axis of the grinding head 5. As the grinding head 5, and hammer elements 27 carried thereby, rotate in a counterclockwise direction with respect to FIG. 2, as indicated by the arrow therein, the hammer elements 27 engage the leading end of the slab X in a direction which tends to compress the leading end portion of the slab X directly toward the underlying guide plates 63, without tending to pull the slab of hay into the grinding chamber. Further, in view of the fact that the slab X is carried at a higher level than normally, the tooth-equipped ribs 34 of the feeding rotor 6 are disposed in engagement with the slab until a much smaller unsupported slug remains at the trailing end of the slab than heretofore. The inner ends of the guide plates 63 support the remaining slug as it is chopped away by the rotating hammer elements 27 until the slug is substantially disintegrated, or cut down to such small size as to be ineffective to hinder the smooth operation of the hammermill.

An added advantage of the feed control device above described lies in its use as a guide for grain and the like to the interior of the chamber 3. The guide plates 63 cooperate with the base plate 58 to define upwardly opening parallel channels which guide the grain for uniform feeding over the entire width of the inlet throat 2, so that substantially the entire axial length of the grinding head 5 is utilized in grinding the material. This is particularly important when the hammermill is mounted on a portable vehicle, when the vehicle is in such position that the axis of the grinding head shaft 25 is tilted.

While the feed control device of this invention has been shown and described as an attachment for existing hammermills, it will be appreciated that the same may be substituted for the bottom wall portions 12a of the hammermill in the manufacture thereof. Further, While we have shown and described a commercial embodiment of our feed control device for hammermills, it will be understood that the same is capable of modification without departure from the spirit and scope of the invention, as defined in the claims.
