Abstract
"MIXING HEAD FOR SOIL TILLAGE"
ABSTRACT OF THE DISCLOSURE
The mixing head comprises a pair of opposed, spaced apart, generally vertical discs that are generally aligned with the direction of travel, although they are slightly angled so as to be wider apart at their front ends than at their rear ends. The discs are rotatably mounted to a free floating frame. Each disc has a plurality of radially extending, elongated, broad, rigid, chisel-like teeth which extend from the disc central portion out beyond its circumferential rim. The discs are driven to rotate against the direction of travel. When rotating, the disc and teeth formations operate to cut down into the soil and excavate it in portions carried by the teeth. The portions are moved inwardly by the angled formations and then thrown and dropped to the rear. The furrow formed has a flat-topped ridge overtopped with a loose mix of excavated soil and humus. The furrow is a good growing site for implanted seedlings.

Description
1 FI~LD OF THE INVENTION
2 The present invention relates to a tooth disc-type mixing
3 head for tilling and mixing soil and urface debris, to provide
4 a furrow useful for the growth of seedlings.
S B~CKGROUN~ OF ~HE INVEN~IQ~
6 The invantion was developed in connection with a research 7 project established to enhance forest renewal techniques.
8 The problem addressed was the need for a relatively high-9 speed mixer which could be pulled by a prime mover over the forest floor in an area that had undergone harvesting or fire.
11 The mixer had to be able to cope with residual "slash" or 12 partæ of trees, decomposing layers of tree parts ("duff"), and 13 dense underground roots.
14 The ob~ectlve was to create a furrow adapted to foster the growth of seedlings planted ln it.
16 SUMM~Ry-ol ~ IO~
17 The lnvention involves a mixing head adapted for use with 18 a tractor or other prime mover, comprising in combination:
19 - a frame that has means, at its forward end, for establlshing a pivot connection with the main frame of 21 the pulling unit, whereby the frame may pivot about a 22 generally horlzontal axis and is preferably "free-23 floating";
24 - a pair of laterally spaced apart, opposed, substantially vertical disas, said discs being 26 rotatably mounted on the frame; ~
qP
- 202379g 1 - ~aid frame carrylng motor and gear means for rotating 2 the disc~ simultaneously against the direction of 3 travel;
4 - each disc carrying a plurality of inwardly protruding elongated, broad, rigid, chisel-like teeth. More 6 particularly, the teeth are preferably radially 7 arranged, project inwardly perpendicularly from the 8 disc face and extend radially outward from the central 9 portion of the disc~to beyond its circumferential rim;
- the discs are preferably angled slightly so as to be 11 wider apart at the front end than at the rear end; and 12 - the frame carries means, projecting laterally 13 outwardly, for bearing against the undisturbed ground 14 ~urface, to limit the extent of penetration of the free-floating disc and teeth formations into the soil.
16 In operation, the teeth enter the debris-laden soil and 17 sweep through it in a forward direction to lift free a portion 18 of excavated material. The succe~sively excavated portions are 19 moved inwardly by the angled formation~ of disc and teeth and are then thrown and dropped rearwardly, to oollectively form an 21 elongated mound of loose mixed soil and humus overtopping a flat-22 topped ridge of undisturbed soil. Slmultaneously, parallel 23 trenches are being formed, running along the two side edges of 24 the mound-covered ridge.
The mound-covered ridge has been found to be effective as 26 a growing site for implanted seedlings.

DESCRIPTION OF ~HE PREFERR~ EMBODIMENT
16 The mixing head 1 has a frame 2 comprislng a 17 horizontally extending box section 3 having a pair of downwardly 18 extending, laterally spaced apart legs 4. The box section 3 is 19 pivotally connected at its forward end by a horizontal pin 5 with the main frame 6 of a pulling unit 7, for plvotlng about a 21 generally horlzontal axls.
22 Each leg 4 carrles at its lower end, on lts outslde 23 surface 8, a hydraulic motor 9 driving a planetary gear box 10.
24 The output shaft (not shown) of the motor and gear assembly extends through the leg 4 and aarries and drives a diso 11. Thus 26 there is provided a discrete motor and gear means for rotating 27 each disc 11.
1 The legs 4 are adjustably mounted with bolts to the box 2 Rection 3 so that they can be swivelled ~lightly and locked- ln 3 place to adjust the relative angularity of the two discs 11. The 4 discs 11, although generally vertical, are positioned 80 as to S be slightly (or acutely) angled, whereby they are further apart 6 at their front edges than at their rear edges. The discs 11, 7 although slightly angled, are generally aligned with the 8 direction of travel.
9 Each disc 11 carries a plurality of radially extending teeth 12 which are broad, rigid and chisel-like in configuration. The 11 teeth 12 extend from the central portion of the disc 11 and 12 protrude beyond its rim 13. The teeth 12 project inwardly and 13 perpendicularly from its inside surface 14. Each disc 11 and its 14 teeth 12 combine to form a separately driven cutting formation or assembly.
16 A concave housing 15 extend6 laterally and outwardly from 17 the outslde surface 8 of eaoh leg 4. The housing 15 extends 18 close to the bottom portion of the disc rlm 13. The housing 15 19 acts as a gage, by bearing agalnst the undlsturbed 8011 and limiting the depth of penetration of the dlsc and teeth 21 formatlons 17.
22 The frame 2, disc and teeth formations 17, and housings lS
23 are all formed of thlck steel to oreate a heavy and rugged 24 as~embly that can penetrate and till the log-strewn forest soil.
The method of operation of the assembly has already been 26 desoribed. The dlso and teeth formations 17 funotion to form a 27 furrow 20 oomprising a flat-topped ridge 21 of undisturbed soil 28 overlain by a mound 22 of loose soil and humus. Two trenohes 23 29 run along the sides of the ridge 21.
