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 33, 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. Th

7、is section is taken on the line 55, 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 desire

8、d 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 7

9、 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 pr

10、e-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 the

11、rewith. 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 fixed

12、 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 against

14、 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 countersha

15、ft 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

16、 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 between the wheels which are rotating rear wardly at thei

17、r adjacent sides. As the beets pass between the wheels the latter are forced outwardly about the axis of the hinge bolts 19 to allow passage of the beets and the latter are thrown from the rear sides of the wheels. It will be noted that this hinged, spring-actuated, swinging action of the wheels all

18、ows them to automatically space themselves in accordance with the size of the beet. A hood 3i is supported from the fixed braces 23 to prevent the beets from passing over the wheels. Should an unusually high beet be encountered or should the plows lift the beets to an unusual height, their crowns wi

19、ll strike this hood and be guided thereby rear wardly between the lifting wheels. It is desired to call particular attention to the construction of the lifting wheels. Each consists of a hub member 32 provided with a plurality of radial spoke sockets. Spokes 33 extend radially outward from the hub m

20、ember to a connection with resilient rim plates 34. The rim plates support a pair of corrugated hoops 35 which form the two side edges of the wheel. The upper hoop is of smaller diameter than the lower hoop so as to impart a frusto-conlcal shape to the wheel. The two hoops are connected together at

21、the high points of their peripheries by means of cross bars 36. The corrugations in the hoops allow them to conveniently engage the rounded sides of the beets, thus forming beet-receiving pockets, and the open spaces between the cross bars permit the rounded sides to project into the wheels to be fi

22、rmly gripped thereby.It will be noted that the hoops 35 and the cross bars 36 are members of small diameter, in the nature of rods, and by virtue of this construction the area of contact between the lifting wheels and the beet there between is quite small. This has the advantage that, without requir

23、ing excessive spring pressure, encrusted soil, clods and the lie clinging to the beet are broken and fall away from the beet, yet the pressure with which the wheels engage the beet is not great enough to damage it. While a specific form of the improvement has been described and illustrated herein, i

24、t is desired to be understood that the same may be varied, within the scope of the appended claims, without departing from the spirit of the invention. Having thus described the invention, what is claimed and desired secured by Letters Patent is:1. A lifting wheel construction for beet harvesters fo
