1、Sugar beet Harvester The invention is more particularly designed for use with a beet harvester of the type illustrated in applicants copending application Serial No. 324,645, of which this application is a continuation in part.The principal object of the invention is to provide two beet engaging whe
2、els of a highly efficient type which will engage opposite sides of each beet and lift it from the ground； separate it from the clods and soil； and deliver it either back upon top of the ground or to any suitable receiving apparatus, such as a loading conveyor or dump hopper such as used in beet harv
3、esting machinery.Other objects of the invention are to provide beet engaging wheels which will automatically 20 accommodate themselves to differing sizes of beets； which will not become clogged with dirt, trash, clods, etc.； and which will firmly hold the beets in an aligned, upright position.Other
4、objects and advantages reside in the 25 detail construction of the invention, which is designed for simplicity, economy, and efficiency. These will become more apparent from the following description.In the following detailed description of the 30 invention reference is had to the accompanying drawi
5、ng 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 rear view of a typical beet harvester illustrating the improved beet lifting mechanism in place thereon； Fig. 2 is an enlarged rear view of the impr
6、oved beet lifting wheels； Fig. 3 is a longitudinal section through one of the wheels, taken on the line 3 3, Fig. 2；Fig. 4 is a top view of one of the wheels removed from its shaft； and Fig. 5 is a cross section through a portion of 45 the wheel supporting frame, with the wheel removed there from. T
7、his section is taken on the line 5 5, Fig. 3.In Fig. 1, the rear extremity of a typical tractor, to which a beet harvesting mechanism is attached, is indicated at 10 with the wheel thereof at i!. The improved lifting mechanism may be supported from a fixed frame (3 secured to the tractor in any desi
8、red manner, for instance, as illustrated in applicants copending application, Serial No. 324,645. A vertically movable frame 12 is mounted on the fixed frame !3 and can be raised and lowered thereon by a lift lever 9 secured on a power lift rockshaft 8, which is connected to the power lift mechanism
9、 7 of the tractor (0. The lever S is connected to the vertically movable frame !2 by chain links 6 and a rod 5 passing through the lower link and hooked at opposite ends to the frame 12. The rockshaft 8 is suitably joumaled in the upper portion of the fixed frame 13. The proper digging depth can be
10、pre-set by means of a threaded adjusting crank 4, threaded through a projecting portion 3 of the movable frame f 2, and contacting the fixed frame i 3 to limit the downward movement of the movable frame 12. The entire lifting mechanism is supported from this movable frame and is raised and lowered t
11、herewith. The lifting mechanism comprises a pair of open, multi-sided, conical, lifting wheels mounted on wheel shafts 16 in shaft journals 17. The journals IT are secured on the lower extremities of hinged arms 18. Each of the hinged arms 13 is mounted on a hinge bolt 19 on the extremities of a fix
12、ed bar 20. The bars 20 extend downwardly from the vertically movable frame 12.This construction allows the shafts 16 to swing freely sideward from the hinge bolts i 9. The two shafts and, of course, the wheels thereon are constantly urged toward each other by means of suitable compression springs 21
13、. The compression springs are compressed beneath the heads of bolts 22 which extend through the lower extremities of a pair of fixed braces 23. The fixed braces are permanently secured to a cross bar 24 in the vertically movable frame 12. Thus, as the two wheels are forced apart, they will act again
14、st the springs 2!.Power is transmitted to the wheels through the medium of universal joints 25 which connect each of the shafts IS with a gear shaft 26. The gear shafts are mounted in fixed bearings !5 and are rotated through the medium of beveled gears 2 T mounted on a countershaft 28. The counters
15、haft is driven from any suitable source of power, for instance, from the axle of the tractor wheel II, through the medium of a drive chain 29.The lifting wheels are supported in spaced relation with their axes at a rearward and downward incline directly to the rear of a pair of beet lifting plows. The position of such plows is indicated at 30, in Fig. 1 and in broken line in Fig. 3. These plows engage the earth along the opposite sides of a row of beets and act to lift thebeets and the clods from the row. The lifted beets are then engaged
