AND PULLING ROOTS
ABSTRACT OF THE DISCLOSURE
Normally clearing land having small trees, bushes and the like requires several independent treat-ments and is time consuming as well as being labour intensive. The present device consists of a frame which may be pulled by a tractor or the like and includes a traction wheel or drum adjacent the front thereof, a root picking and raking drum adjacent the rear thereof and drives said traction drum with a transverse shear blade depending from the frame between the traction drum and the raking drum to lift and return a layer of soil and to shear off any roots at the depth of the shearing blade whereupon these roots can be raked to the surface of the soil by the raking drum which is controlled from the traction drum in a manner whereby the speed of rotation of the surface of the raking drum is less than the speed of the device over the ground surface. The energy produced by retarding the speed of rotation of the raking drum is applied to and utilized by the traction drum to reduce the power required to pull the machine forward. A
cleaning scraper is provided to maintain the raking teeth on the raking drum in a relatively clean condition.

POWER ASSISTED DEVICE FOR BREAKING LAND
AN~ PU~.LING RO~S
BAC~GROUND OF THE INVENTION
This invention relates to new and useful improvements in devices ~or 6011 cultivation, and partic-ularly in-the clearing of scrub land which may contain bushes, small trees and the like or raw land from which trees have been removed.
Several conventional methods are presently practiced for such c:Learing and include firstly, plowing the land then discing the same and picking the roots therefrom.
The disadvantages of such a method include the fact that most roots are in the top portion of the soil and when same is turned over by a plow, the root crown is usually underneath the surface and is difficult to work out of the soil and will often continue to grow if left in the soil. Furthermore many areas of top soil cleared in this manner, will not grow well for several years where the top soil is plowed under and the subsoil is exposed.
Another method is rototilling in which the roots are cut into small chips and mixed in with the soil. While decaying, these roots use all of the avail-~2SU1~26 able nitrogen so that it is several years before nitrogenis available for crop growth.
A large amount of energy is required to roto-till land so that it is extremely costly. Furthermore the rototiller teeth rotate at a fast speed and will often break if they strike rocks or stones over a few inches in dia~eter so that they are not particularly suitable in soils where rocks are present. The same difficulty occurs when relatively large roots are encountered by the rototiller.
The third method in common use includes discing with a heavy disc implement. However, once again most of the wood stays in the soil thereby consuming nitrogen while it decays and many areas require repeated discing to get to the required cultivating depth and is therefore very costly.
SU~MARY OF TH~ IN~E~TION
The present invention overcomes all of these disadvantages and is de~igned to reduce the cost of breaking and clearing roots fro~ raw 1and that has small trees only or breaking and clearing root~ from raw land in which the trees have been removed previously.
The present device shears a layer of soil a predetermined depth below the surface but does not turn )4~
it over like a plow so that the top soil remains in position. At the same time it shears ~ff the roots of any bushes or trees at this level and includes a toothed roller whic~- then pul~s the roots free of the soil and drops them on top of the soil in one operation.
This single implement therefore breaks the land, cultivates the soil and puts the roots on the surface thereof where they can be raked easily into windrows thereby leaving the good top soil at or near the surface ~or maximum crop growth. Once the roots are sheared they are easier to rake to the surface than if they have been turned over as with a plow or the like.
Furthermore, the majority of the wood content is removed thereby ireeing available nitrogen for crop growth rather than for rotting .he wood which normally remains in the soil when cleared by conventional methods.
One aspect of the invention is to provide a device for breaking land and pulling roots comprising in combination a frame, means supporting the frame a pre-determined distance above the ground surface, a subsoil blade depending from the frame and extending thereacross, said subsoil blade adapted to lift and return a layer of soil and to shear off tree roots and the like at a pre-~2S[J~;26 determined depth below the ground surface, root pullermeans journa~led for rotation in said frame rearwardly of said blade, for raking severed roots from the layer of soil and depositing same on the surface of the layer of soil and means to ret~rd rotation of said root puller means.
Another aspect of the invention is to provide a frame with a traction drum at the front end thereof, a shear plate behind the traction drum set at a predeter-mined level below the surface, and a toothed raking roller behind the shear blade that drives the traction drum. The energy producted by retarding the rotation speed of the toothed roller assists in pulling the machine foreward. As the implement moves forward the teeth on the raking drum tears and lifts roots from the sheared layer and to deposit same upon the surface.
A further advantage of the present device is to provide an implement of the character herewithin describ-ed which is simple i~ construction, economical in manu-facture and use a~ otherwise well suited to the purpose for which it is designed.
With the foregoing in view, and other advan-tages as will become apparent to those skilled in the art to which this invention relates as this specification ~Z'5~)4Z6 proceeds, the invention is herein described by reference to the accompanying drawings forming a part hereof, which includes a description of the best mode known to the applican~ and o~ the preferred typical embodiment of the principles of the present invention, in which:

DESCRIPTION OF THE DRAWINGS
Figure 1 is a partially schematic side view of the device.
Figure 2 is a partially schem~tic top plan view of Figure 1.
In the drawings like characters of reference indicate corresponding parts in the different figures.
DETAILED DESCRIPTION
Proceeding therefore to describe the invention in detail, reference to the accompanying drawings will show a frame collectively designated 10 consisting of a pair o~ spaced and parallel longitudinally extending members 11 together with transverse members 12 thus form-ing a substantially rectangular frame when viewed in plan.
A hitch assembly collectively designated 13 consists of a hitch member 14 for attachment to a tractor or the like with a p~ir of diverging hitch pulls 15 extending rearwardly and outwardly from the hitch member ~2S(~4~Z6 14 and being pivoted by means of pivot pins 16, to the front ends 17 of the longitudinal frames members 11.
Transport wheel assemblies 18 are situated adjacent the rear ends 19 of the frame members 11 and consist of crank arms 20 carrying ground engaging wheels 21 which ar~ conventional in construction and which may be engaged or disengaged with the ground by means of hydraulic piston and cylinder assemblies 22 extending between the frame and the crank arms 20 and operated from the source of hy~rau7ic power within the towing means such as a tractor (not illustrated).
Mounted transversely within the frame adjacent the front end thereof is a shaft 23 journalled within pillow bearing blocks 24 on each side member 11. A trac-tion wheel or drum 25 is secured to the shaft between the longitudinal Erame members 11 and is provided with trans-versely extending ground engaging teeth 26 as shown in the drawings and these teeth engage the surface 27 of the ground when the device is in operation as will herein-after be described.
Situated rearwardly of this traction drum 25, is a soil shearing blade assembly collectively designated 28. It consists of a pair of downwardly depending stand-ards 29, one from each of the side frame members 11 with
2~
a transversely situated soil shearing blade 30 secured to the lower ends thereof and situated substantially par-allel t~ the ~r~nd qu~face 27, when in operation.
It will be seen fro~ ~igure 1, that this shear blade 30 is situated a predetermined distance below the ground surface controlled by the depth of the standards 29 and the engagement of the traction drum 25 with the ground surface, together with a raking and root pulling means collecti~ely designated 31 situated within the frame 10 adjacent the rear end thereof and rearwardly of the shearing blade assembly 28.
This assembly 31 consists of a shaft 32 jour-nalled transversely within the frame 10 by pillow blocks 33 and having a drum 34 secured thereto and for rotation therewith. A plurality of raking teeth 35 extend from the surface of the drum in parallel rows as shown in Figure 2 and equidistantly spaced around the surface of the drum as shown in Figure 1. The drum rotates in the direction of arrow 36 as will hereinafter be described and the teeth extend from the surface of the drum in trailing relationship therewith, with reference to the direction of rotation of the drum, as clearly shown in Figure 1.
The diameter of drums 25 and 34 are substan ~25~)~26 tially similar so that when the device is in the ground working position shown in Figure 1, the surfaces o both of these drums engages the ground surface and maintains the frame substantially level a predetermined distance above the ground and the blade 30, substantially hori-zontal to the surface and a predetermined depth below the surface of the grou~d.
Tooth cleaning scraper means collectively designated 37 consist of a heavy duty plate 38 extending across the frame between members 11 immediately rearward-ly of the raking drum 31 and a plurality of recesses or cut outs 39 are formed in the front edge of this plate through which the rows of teeth 35, pass as they leave the soil and move upwardly through these recesses or cut outs thus c].eaning any debris such as mud, roots or the like, from the teeth immediately after they have left the soil.
Retarding the root puller means collectively designated 31 produces the rotative power that drives traction drum 25.
The aforementioned traction of drum 25 and shaft 23 supply the rotative power to the root puller means collectively designated 31 and in this connection a sprocket or pulley 40 is secured to shaft 23 outboard of ~;~SV~26 frame 11.
A sprocket ~hain or belt 41 extends around this sprocket or pulley and a correspo~ding sprocket or pulley ~2 secured to the drum shaft 32, also outboard of the frame member 11 and it will be observed that although the two drums 25 and 34 are similar in diameter, the sprocket or pulley 42 is larger than the sprocket or pulley 40 thus causing the drum 34 to rotate at a slower speed than the traction drum 25.
This means that the rotational speed of the drum 34 is less than the rotational speed of the drum 25 and hence is less than the speed of movement of the frame across the ground so that, with the drum 34 rotating in the direction o~ arrow 36, the teeth speed is retarded to make each tooth tear through the soil for a certain distance thus assisting in pulling the roots free.
The roller 34 continues to rotate so that new teeth penetrate the soil and loosen the roots while the teeth already in the soil move back to the cleaning scraper whereupon roots are removed and deposited upon the surface of the soil layer sheared off by the shear blade 30. It should be noted that this soil layer is not turned over as wlth a plow or discer or the like so that the top soil remains in the upper most desired position ~S()426 and is thoroughly raked and cleaned by the action of the assembly 31.
~ r~ .ivel~ large amount of energy is there-fore absorbed by the trac~ion dru~ 25 as it is driven from the raking drum 34, which reduces the power require-ments of the source of power such as a tractor (not illustrate~)~
It will be observed that, due to the pivoting of the hitch assembly 13, to the frame, the frame is supported upon the drums 25 and 34 within use but for transportation purposes, the transport wheels 21 may be lowered by the hydraulic piston and cylinder assemblies 22 thus raising the frame and lifting the drum 34 to-gether with the shear blade 30, clear of the ground.
It will therefore be seen that the assembly is relatively simple in construction with the rotational retarding power of the root pulling drum assembly 31 being supplied to tl~e traction drum 25 in a simple and economical manner.
Since various modifications can be made in my invention as hereinabove described, and many apparently widely differerlt embodiments of same made within the spirit and scope of the claims without departing from such spirit and scope, it is intended that all matter ~;25(~
contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense.
a transversely situated soil shearing blade 30 secured to the lower ends thereof and situated substantially par-allel t~ the ~r~nd qu~face 27, when in operation.
It will be seen fro~ ~igure 1, that this shear blade 30 is situated a predetermined distance below the ground surface controlled by the depth of the standards 29 and the engagement of the traction drum 25 with the ground surface, together with a raking and root pulling means collecti~ely designated 31 situated within the frame 10 adjacent the rear end thereof and rearwardly of the shearing blade assembly 28.
This assembly 31 consists of a shaft 32 jour-nalled transversely within the frame 10 by pillow blocks 33 and having a drum 34 secured thereto and for rotation therewith. A plurality of raking teeth 35 extend from the surface of the drum in parallel rows as shown in Figure 2 and equidistantly spaced around the surface of the drum as shown in Figure 1. The drum rotates in the direction of arrow 36 as will hereinafter be described and the teeth extend from the surface of the drum in trailing relationship therewith, with reference to the direction of rotation of the drum, as clearly shown in Figure 1.
The diameter of drums 25 and 34 are substan ~25~)~26 tially similar so that when the device is in the ground working position shown in Figure 1, the surfaces o both of these drums engages the ground surface and maintains the frame substantially level a predetermined distance above the ground and the blade 30, substantially hori-zontal to the surface and a predetermined depth below the surface of the grou~d.
Tooth cleaning scraper means collectively designated 37 consist of a heavy duty plate 38 extending across the frame between members 11 immediately rearward-ly of the raking drum 31 and a plurality of recesses or cut outs 39 are formed in the front edge of this plate through which the rows of teeth 35, pass as they leave the soil and move upwardly through these recesses or cut outs thus c].eaning any debris such as mud, roots or the like, from the teeth immediately after they have left the soil.
Retarding the root puller means collectively designated 31 produces the rotative power that drives traction drum 25.
The aforementioned traction of drum 25 and shaft 23 supply the rotative power to the root puller means collectively designated 31 and in this connection a sprocket or pulley 40 is secured to shaft 23 outboard of ~;~SV~26 frame 11.
A sprocket ~hain or belt 41 extends around this sprocket or pulley and a correspo~ding sprocket or pulley ~2 secured to the drum shaft 32, also outboard of the frame member 11 and it will be observed that although the two drums 25 and 34 are similar in diameter, the sprocket or pulley 42 is larger than the sprocket or pulley 40 thus causing the drum 34 to rotate at a slower speed than the traction drum 25.
This means that the rotational speed of the drum 34 is less than the rotational speed of the drum 25 and hence is less than the speed of movement of the frame across the ground so that, with the drum 34 rotating in the direction o~ arrow 36, the teeth speed is retarded to make each tooth tear through the soil for a certain distance thus assisting in pulling the roots free.
The roller 34 continues to rotate so that new teeth penetrate the soil and loosen the roots while the teeth already in the soil move back to the cleaning scraper whereupon roots are removed and deposited upon the surface of the soil layer sheared off by the shear blade 30. It should be noted that this soil layer is not turned over as wlth a plow or discer or the like so that the top soil remains in the upper most desired position ~S()426 and is thoroughly raked and cleaned by the action of the assembly 31.
~ r~ .ivel~ large amount of energy is there-fore absorbed by the trac~ion dru~ 25 as it is driven from the raking drum 34, which reduces the power require-ments of the source of power such as a tractor (not illustrate~)~
It will be observed that, due to the pivoting of the hitch assembly 13, to the frame, the frame is supported upon the drums 25 and 34 within use but for transportation purposes, the transport wheels 21 may be lowered by the hydraulic piston and cylinder assemblies 22 thus raising the frame and lifting the drum 34 to-gether with the shear blade 30, clear of the ground.
It will therefore be seen that the assembly is relatively simple in construction with the rotational retarding power of the root pulling drum assembly 31 being supplied to tl~e traction drum 25 in a simple and economical manner.
