This invention relates to "a feed grinding mill for grinding and elevating stock feed and ensilage. The principal object of the invention is to provide an exceedingly simple and highly efficient grinding device which will have a maximum outputfor 'a minimum of power.
Other objects and advantages reside in the detail construction of the invention, which is designed for simplicity, economy, and efliciency,
These will become more apparent from the following description.
In the following detailed description of the invention, reference is had to the accompanying drawing which forms a part hereof. Like numerals refer to like parts in all views of the drawing and throughout the description.
In the drawing:
Fig. 1 is a perspective view of the improved feed grinding mill; and
Fig. 2 is a cross section therethrough.
The entire mill is formed from standard structural materials and does not require special castings, shapes, and the like. It comprises a rectangular grinding chamber formed from two side plates I and II, two end plates l2 and I3, and a bottom plate I4. A plurality of tie bolts I6 pass through the two end plates I2 and I3 to clamp the entire structure together. When the bolts I6 are tightened, the side and bottom plates III, II, and I4 are firmly clamped between the end plates. The internal pressure forces the side plates outwardly against the bolts.
The end plates I3 are flanged outwardly at their bottoms as shown at IT, so that they may hook beneath base bolts I8. which extend between angle frame members I9. A shaft bracket member 20 is also clamped between the base members I9 by means of a third base bolt 2I.
A stationary shaft rod 22 extends between the end plate I3 and the bracket 20, passing through an air intake opening 23 in the end plate I2.
The rod 22 is locked in place by means of suitable lock nuts 24. A tubular shaft sleeve 25 surrounds the rod 22 and is rotatably mounted thereon upon suitable anti-friction bearings 26. Two beater blades 2! are welded to the opposite sides of the shaft sleeve 25 and extend equally outward therefrom in parallel relation. These blades are of slightly less length than the length of the side plates I0 and II so that they may rotate freely therebetween.
A sheet metal hopper 28 is fitted into the top of the grinding chamber, and is secured to an upwardly projecting lip 29 on the end plates by means of suitable attachment bolts 30. The hop- 3 top of the beater housing.
covers the remainder of the top offthe chamber per 28'is formed with-an inclined bottom'plate 2!! extending over the top of the grinding chamber. H The hopper 28 covers about one-half of the beneath the inclined bottom plate 3|.
A conveyor tube 33 of any desired length, depending upon where the ground feed is to be deposited, is telescoped over the extremity ofthe discharge head 32 and is secured in place between clamping bars 34 and 35. by means of suitable clamping bolts 36. The bar 35 is riveted or otherwise secured to the inclined bottom plate 3|.
A gate plate 31 is slidable within the hopper 28 so that it can be inserted to cont-act the plate (H to shut off the supply of material to the beater chamber. This plate can be drawn outwardly to provide any desired feed opening or throat, and can be locked or clamped in its final adjusted position by means of a clamp bolt 38 and clamp nuts 39.
A first breaker bar 40 is welded or otherwise secured across the lower part of the side plate Ill, and a second breaker bar 4| is welded or otherwise secured across the bottom plate It. The bars 40 and 4| are positioned closely adjacent to the peripheral path of the beater blades 21.
In use, the material to be ground is fed into the hopper 28 and flows through the throat between the plate 31 and the plate 3| to the rapidly revolving beater blades 21. These latter blades first throw the material against the side plate I0, thence against the breaker bar 49, thence against the bottom plate I4, thence against the breaker bar 4! thence against the side plate I I, and then into the discharge head 3|. This plurality of impacts combined with the high speed of rotation of the beater blades 21 results in a rapid and efficient attrition of the material, and discharges it at high velocity from the discharge head 3 I.
The beater blades 21 act as a blower as well as a beater, the air being taken inthrough the intake opening 23 in the end plate I2 and blown with the ground material from the discharge tube 32.
It will be noted that a portion of the shaft sleeve 25 projects beyond the end plate I2 to serve as abelt pulley for driving the beater blades.
While a specific form of the improvementhas been described and illustrated herein, it is desired to be understood that the same may be varied, within the scope of the appended. claim,
Adischarge head 32 without departing from the spirit of the invention.
Having thus described the invention, what is claimed and desired secured by Letters Patent is:
A grinding mill comprising: two side plates; two end plates; a bottom plate; a plurality of bolts extending between said two end plates and clamping the latter against the ends of said side and bottom plates; saidfibolts being positioned},
and of a length substantially equal to that of the rod; and a beater blade secured to each side of said tubular shaft sleeve said blades extending equally outward from said shaft in parallel relation between said end plates.
