Description
~LZ~08~3~7 Various forms of grasses including chaffy seed grasses are becoming popular for grazing and large scale seeding operations for grasses which include chaffy grass seed are relatively expensive due to the extensive seed processing operations which must be performed in order to produce a seed product which is clean, substantially pure and includes minimum seed damage.
Present steps to process chaffy seed grasses include the use of a hammer mill to separate the seed from the grass stem and subsequent seed cleaning treatment to debeard and deglume the seed. However, hammer mills cause high percentage of seed damage and present apparatuses utilized to debeard and deglume seed are only minimumly effective and tend to cause greater damage to the seed.
Accordingly, a need exists for apparatus by which seed may be more efficiently removed from grass stems and debearded and deglumed. The present invention is concerned primarily with more efficient removing of the seed from the grass stems with minimum damage to the seed.
Examples of previously known devices including some of the general structural and operational features of the instant invention are disclosed in U.S. patent ~os. 640,793;

Referring now more specifically to the drawings the numeral 10 generally designates a grass seed removing apparatus including an upstand-ing frame 12 from whose upper portion front and rear pairs of transversely aligned rollers or wheels 14 and 16 are journaled. The rollers 16 are ~mounted on a transverse shaft 18 for rotation therewith and the shaft 18 ~l ~ 5~ ~ /~
A i9 driven by an electric motor 20 through a ~ speed or variable speed reduction assembly 22.
A cylindrical drum referred to in general by the reference numeral 24 is provided and includes a wire mesh cylindrical body 26 and opposite end walls 28 and 30. The end walls 28 and 30 include cylindrical portions 32 rollingly engaged with the wheels 14 and 16 and radial flange portions 34 on the remote sides of which the wheels 16 are disposed. One of the end walls 28 and 30 is openable in order to load the drum 24.
The frame 12 also supports an elongated sieve assembly referred to in general by the reference numeral 40 including rigidly interconnected opposite side walls or plates 42 extending longitudinally thereof as well as transversely spaced longitudinally extending partition walls or plates 44 disposed between the side walls 42. A plurality of elongated transversely 39~7 corrugated strip members or sections 46 are tran6versely spaced apart along longitudinally extending upper and lower reaches 48 and 50 of sieve assembly 40. Strip members 46 are secured between each of the side wall3 42 and the adjacent partition wall 44 and between each pair of adjacent partition walls 44. me strip members or sections 46 are transversely corrugated as at 52 and the reaches 4$ and 50 are downwardly inclined toward the discharge end 54 of the sieve assembly 40. The upper inlet end 56 of the sieve assembly 40 has the lower end of an inclined chute 58 registered therewith and the chute 58 underlies that portion of the drum 24 which is not in vertical registry with the upper end of the upper reach 48 of strip members 46.
Corresponding portions of adjacent strip members 46 in each reach 48 and 50 thereof are dispo~ed in parallel planes oppositely inclined relative to the inclination of the sieve assembly 40. Further, longi-tudinal central portions of the opposite side walls 42 have openings 60 formed therein in which the opposite ends of a cover tube or pipe 62 are secured. An eccentrically weighted shaft 64 extends through the tube or pipe 62 and includes diametrically reduced end portions 66 journaled from journal blocks 68 mounted on the outer sides of the side walls 42 in registry with the openings 60. In addition, the frame 12 includes a hori-zontal support 70 on the right side thereof which mounts an electric motor 72 whose rotary output shaft 74 is drivingly coupled to the adjacent end of the shaft 64.
The sieve assembly 40 includes a plurality of inclined upwardly opening troughs 76 which underlie the lowermost reach of strip members 46 and each opposite side of the upper end of the sieve assembly 40 is sup-ported from the frame 12 by a plurality of elongated elastic members 78 having their upper ends mounted to the frame 12 as at 80 and their lower ends anchored relative to the sieve assembly 40 as at 82. Similar sets of elongated elastic members 83 are utilized to support opposite sides of the lower end of the sieve assembly 40 from the rear of the frame 12. It will ~L2~LqD~
be noted that both the front and rear end portions of the frame 12 include vertically spaced apertures 84 by which the upper ends of the elastic members 78 and 83 may be vertically adjusted so as to vary the inclination of the sieve assembly 40.
From Figures 2, 3 and 4 of the drawings it will be seen that an inclined combined collection and discharge chute 86 is also suspended from the frame 12 and the lower end of the assembly 40 through the utilization of additional elongated elastic members 88 and, accordingly, the chute 86 is also supported for vibration relative to the frame 12 as a result of operation of the motor 72.
The shaft 64 substantially parallels the strip members 46 and accordingly, the sieve assembly 40 is vibrated in an omnidirectional manner within a plane disposed normal to the sieve members 46. Further, although the motor 72 is supported from the frame 12, the rotary output shaft 74 thereof is connected to the shaft 64 through a flexible drive member such as a rubber tube or the like of sufficient length so as not to interEere with vibration of the assembly 40.
In operation, cut seed bearing grass stalks are deposited into the drum 24 and the motor 20 is actuated along with the motor 72. During operation of the motor 20 the drum 24 slowly rotates and discharges seed bearing cut grass stems therefrom down into the sieve assembly 40. The upper reach 48 of strip members 46, as a result of vibration of the sieve assembly 40, removes the major stem portions of the cut grass from the seed bearing short stem and green strips. The major stem portions fall from the lower end of the upper reach 48 and the short seed bearing grass stems and green strips fall through the first reach 48 onto the second reach of strip meTnbers 46. The second reach of strip members 46 are more closely spaced and serve to remove the seeds from the short steTns and green strips being vibrated on the lower reach 50. The removed seeds fall downwardly between the strip members 46 and into the troughs 76 for movement downwardly there ~Z4089~
along. The removed seed is discharged from the lower ends of the troughs 76 into the inclined chute 86 and the collected seeds are then discharged from the lower end of the chute 86 into a suitable receptacle ~not shown) therefor.
The short stem and green strip portions vibrated by the lower reach 50 of strip members 46 move downwardly along the reach 50 and are discharged from the lower end thereof.
The incline of the sieve assembly 40 is approximately 20 and the strip members 46 are substantially oppo~itely inclined approximately 20 relative to the horizontal.

Corresponding portions of adjacent strip members 46 in each reach 48 and 50 thereof are dispo~ed in parallel planes oppositely inclined relative to the inclination of the sieve assembly 40.
