Oblique submerged reverse deep rotary tillage device
First Claim
1. An oblique submerged reverse deep rotary tilling device configured to be connected to a tractor (23), the device comprising:
- a stander (1), a mounted frame (2), a gearbox (3) and an oblique blade roller (5) connected to the stander (10), wherein;
the mounted frame (2) is connected to the stander (10) to orient the oblique blade roller (5) at an angle of 55 to 70°
to an advancing direction (V) of the tractor (23);
the gearbox (3) is located at a center of the stander (1);
the gearbox (3) has a power input shaft (25) configured to be linked with a power take-off (PTO) shaft (24) of the tractor (23) by a universal joint (26) so that the power input shaft (25) is at an angle of 110 to 125°
to the advancing direction (V) of the tractor (23);
the gearbox (3) has a power output shaft (17) that is a splined shaft connected to an oblique blade roller shaft (7) of the oblique blade roller (5);
the oblique blade roller (5) has rotary blades (6) and the oblique blade roller shaft (7) has oppositely-disposed first and second ends connected to bearings (18) supported by bearing seats (4,21) fixed on oppositely-disposed ends the stander (1), the first end of the oblique blade roller shaft (7) being behind the second end of the oblique blade roller shaft (7) in the advancing direction (V) as a result of the mounted frame (2) orienting the oblique blade roller (5) at the angle of 55 to 70°
to the advancing direction (V);
tips of the rotary blades (6) are bent toward the second end of the oblique blade roller shaft (7); and
a column of side force balance blades (16) are mounted to the oblique blade roller (5) and rotate in a plane that is parallel to the advancing direction (V), and the side force balance blades (16) have a rotating center axis disposed at an angle of 20 to 35°
to the oblique blade roller (5).

Abstract
An oblique submerged reverse deep rotary tilling device configured to be connected to a tractor. The tilling device includes a stander, a mounted frame, a gearbox and an oblique blade roller. The oblique blade roller has configured rotary blades whose tips bend to the same direction. The angle between the rotary tilling blade roller and an advancing direction of the tractor is 55˜70° while the rotary blade tips are all toward the right side of the advancing direction. Side force balance blades are installed to the left side of the oblique blade roller, rotate in a plane that is parallel to the advancing direction, and have a rotating center axis disposed at an angle to the oblique blade roller to balance the axial component force of the oblique blade roller.
