Abstract

The arrangement is for fitting a tool against the ground surface for clearing snow and ice and transporting the cleared material away and involves the scoop (1) being fitted with side devices (4,6) and wings/flaps (5) which do not require to be folded inwards when ground levels limiting scraping are encountered. The wings/flaps are individually movable both vertically and horizontally and can be pushed from an inwardly lowered position back to a forward position, approximately at 90 degrees to the scoop base cutter. Once the tool has passed a raised ground formation the side devices and the wings/flaps are returned to their original position with the aid of springs.

Description

527,095 f; 2 3 2 ß '.' o J o o o o o. o c c o a o o O n on Purpose of the invention The present alignment aims to create the conditions for developing a method and a device that means that snow and ice can be released and transported away from areas where this must take place.

The invention is further adapted to a device which, without the participation of advanced technology or the intervention of the operator, adapts the abutment to the ground level.

The main purpose of the present invention is to provide a device which can, as far as possible, adapt the abutment to the ground surface without the participation of advanced and costly control and regulation equipment.

Since parts of the device can be folded out by about 90 degrees in relation to the leading edge of the bucket, both efficiency and maneuverability increase significantly compared with conventional constructions.

For another year, maintenance costs on the bucket will be reduced due to the wear on the steel of the flaps. The device can be used in full without special adaptation, regardless of the thickness of the bucket's cutting insert.

Brief description of the inventive concept The above and further jam is achieved by a device according to the invention which has the features stated in the claims. According to a preferred embodiment of the invention, said method and device is designed with movable side devices with side clips for a bucket, which is intended to partly scrape away snow and ice, and partly collect the snow and ice scraped from the substrate for further transport from the area.

These seams are achieved according to the invention in that the side devices of the bucket are individually movable in the vertical plane and the side flaps are individually movable guided by irregularities in the ground plane.

Thanks to this, the front edge of the bucket will in all layers abut the ground level without extensive efforts by the operator or from advanced control and regulation technology. The result will be cheaper and more efficient devices for the intended area of operation.

An open bucket / plug (1) is composed of a rear wall (2) with varying fastening devices (3) for connection to a vehicle which operates during the work of releasing areas from snow and ice. The sides (4) of the bucket / plow collect snow and ice from an area bounded by the bucket / plow (1) and the wings / flaps (5).

The wing blades / blades (5) can be unfolded from a bucket and folded in to the side of a bucket / plow with the support of cylinders (6) which are controlled from the base vehicle by the driver. The wings / flaps (5) are constantly subject to folding and unfolding when various obstacles occur while driving.

The Vingania / Klafïarna (5) must currently be controlled by the operator in the existing devices to carry out the work operations.

The leading edge of the bucket (7) must be connected to the ground plane in order to be able to release the ground plane from snow and ice. With current constructions, the wings / flaps (5) must thus be folded in towards the sides to enable efficient snow and ice removal.

Figure 2 illustrates a situation where the wings / flaps (5) have been folded in towards the sides of the bucket / plow by means of the hydraulics controlled by the driver. With current constructions of buckets / plows, the operations with unloading and adjustment of the bucket / plow's wings / flaps must take place continuously in order for the front edge (7) of the bucket to be used for scraping snow and ice from the ground.

Figure 3 shows how the wings / plow wings (5) of the bucket / plow can be folded in and out with a cylinder by arranging the wings / flaps (5) to the sides (4) of the bucket / plow with a hinge (8) or hinge-like loading devices.

Figure 4 shows from the side the principle where the sides (4) of the bucket / plow have been made in two parts through a dividing line (9) extending from the upper edge (2) of the bucket / plow (1) rear wall (2) to the front edge of the bucket / plow ( 7). The upper part (1 l) or the sides of the bucket / plow now become foldable in relation to the lower part (12) of the bucket / plow which becomes fixed to the back wall (2) and bottom plate (13) of the bucket / plow. The upper part (1 1) of the bucket can now be folded inwards and outwards by the dividing line (9) being assembled with a number of hinges (14) or hinge-like devices. In addition to hinges, the dividing line (9) has been fitted with one or more resilient straps (15) that guide the bucket / plow wings / pliers (5). 5 2 7 0 9 5 5 ";" ïf. s "z 5::: Figure 5 shows the function of the pitch (9) of the sides (4) of the bucket / plow. As soon as an irregularity (16) occurs, the wings / flaps (5) of the bucket / plow (5) will be pressed upwards while the front edge (7) of the bucket / plow (1) still abuts the ground plane (17).

The bucket / flaps (5) of the bucket / 'plow can go over all kinds of obstacles (16) without either manual or other efforts. This is made possible by the upper part of the bucket folding inwards along the dividing line (9) when an obstacle (16) appears on the ground level (17). As soon as the wing / flap (5) has passed an obstacle (16), the wing / flap (5) returns to its normal position as a result of a number of resilient band irons (15) restoring the upper part (11) of the wing / flap to its original position. location.

Figure 6 illustrates a situation where the wings / flaps (5) have been folded in towards the vertically movable side devices (18) of the bucket / plow by means of the hydraulics (6) controlled by the driver. The movable wings / flaps (5) can follow the ground (17) by means of a pivot pin (23) regardless of whether the bucket / plow (1) is to some extent raised at the rear edge.

Adjustment of force to ground (17) is controlled by compression springs (20).

Figure 7 shows how the wings / flaps (5) of the bucket / plow (1) can be folded in and out by means of cylinders (6) operated by the driver.

Wings / flaps (5) are connected to vertically movable side device (18) by hinge-like devices (8). Wings / valves (5) are connected to stop (24) by circumference (25) and pivot pin (23). Stops (24) are connected by movable side devices (18) by hinge-like devices (8).

Figure 8 shows the vertically movable side device (18) of the bucket / plow with applied stop (24) and wing / clamp (5) in a vertical movement through pivot pin (19) and circumference (25), in a side view, height relative to the ground ( 17). The wing flap (5) can, by means of a pivot pin (23) and circumference (25) as well as the action of the spring (26), follow the current ground level substantially different from the ground level at the front edge of the bucket (7).

Figure 9 shows a possible technical solution of the wing / clamp (5) control device (27) for enabling the mobility shown.

Figure 10 shows how the wings / plow (1) of the bucket / plow (1) can be dropped approx. 90 ° straight ahead in relation to the front edge (7) of the bucket / plow by means of control device (27) and cylinders (6) operated by the driver.

Figure I 1 illustrates in a front view how the wings / flaps of the bucket / plow (5) can follow different ground levels (1622) independently of the ground level (17) of the bucket / plow. This makes this invention considerably more efficient than on-market designs.

The described embodiments can of course be varied in many different ways within the scope of the inventive concept.
