Tractor snow thrower with one adjustable collector blade

As is well known, even large amounts of snow have to be removed from the driveways and passageways quickly.

The rotary blowers mounted on the tractor's towing devices, developed for this work, work satisfactorily in dry frost. Their difficulty in operating is on the protective snow, so that the snow collected by the right and left collector blades clogs the centrifuge when they collide, and the snow does not go to the throwing wheel, even if the centrifuge is equipped with special snow feeders.

In a correspondingly developed single-wing centrifuge, where the bait is placed completely on the other side, the snow only moves from the other direction, so there are no encountering snowballs and no blockage, because the higher the specific gravity of the snow, the better it continues to move on the throwing wheel. The single-blade snow thrower has a simpler structure and offers the possibility to change the plowing angle of the collector blade to suit the current condition requirement.

Previously known single-wing snow throwers are disclosed in the following publications: DE-1 918 570, US-1 594 234 and N0 publication No: 88 883.

DE-1 918 570 is a centrifuge developed in front of a car, in which the throwing wheel is fixedly mounted on the left side of the collector blade and the rotational force on the throwing wheel is transmitted directly from the motor at a 90 ° angle to the direction of travel. The centrifugal collector blade can be adjusted to different degrees of angles. The centrifuge can be moved sideways to a small extent.

US-1,594,234 is a centrifuge placed in front of a car, in which the throwing wheel is fixedly placed on the left side of the collector blade and the throwing wheel always rotates parallel to the collector blade. The collector / flywheel combination can be adjusted to different degrees of angle to the direction of travel.

The two snow throwers described above cannot be applied even when converted to a centrifuge to be connected to the tractor's drawbar and power take-off shaft, because direct PTO shaft rotation cannot be realized.

2 78142 NO-Announcement The snow thrower according to publication 122 883 is designed as a centrifuge to be attached to the tractor's lifting device and to the power take-off shaft. The throwing wheel on the left side of the collector blade is positioned at an angle of about 45 ° to the direction of travel, so that the articulation joints of the PTO shaft are at the same angle, which is an absolute requirement for the operation and durability of the PTO shaft. In the centrifuge, the collector blade can be adjusted 90 ° -150 ° to the throwing wheel. The centrifuge cannot be moved laterally.

In addition to the basic adjustment, the now-presented centrifuge can be moved in both lateral directions so that the articulation angles of the PTO shaft are equal and the position of the throwing wheel is maintained at an optimal angle of 90 ° to the direction of travel. In order to achieve the above effect, the invention is characterized by the claims.

Figure 1 shows a top view of a snow thrower connected to a tractor.

Figure 2 shows the snow thrower seen from behind.

Figure 1 shows a single-blade snow thrower, a collector blade (3) connected to the draw and push arms (2) of a conventional tractor (1), for which different plowing angles with respect to the direction of travel are obtained with the adjusting device (4). With the support frame (5) and the flanges (13 and 14) the centrifuge can be moved laterally with respect to both directions. A conventional universal joint shaft (6) rotates a multi-bladed casting wheel (7). The lower corners (8) of the housing form stone pockets into which heavy objects drift. Closing and opening hatches (9) make it easier to empty stone pockets. The hinge pin (10) allows the collector blade to be adjusted. Support structures to strengthen the centrifuge. Swivel snow thrower (12). Adjustable Flanges of Support Frame and Counterparts (13 and 14). Drawbar (15).

Claims (1)

78142 CLAIMS A tractor snow thrower with one adjustable collector blade (3), characterized in that the centrifuge can be moved in both lateral directions relative to the tractor by changing the screw attachment of the flanges (13 and 14) at the ends of the support frame (5) to different positions. there are widenings (8) in the throwing chamber, i.e. stone pockets from which foreign objects can be removed through the hatches (9).
