Abstract

- Invention. Applies to machines for cleaning lawns, squares and parks. The goal: an invention to increase efficiency by increasing the degree of filling of the bunker. The fallen leaf picker contains frame I, on which the drive brush 2 and the hopper 3 are mounted, the loading window 7 of which has a rectangular shape. In the bunker 3, the shield 9 is installed with the possibility of rotation in the vertical plane. Brush 2 throws picked leaves through the window 7 into the bunker 3. As the bunker 3 is filled, the leaves are located in the cavity formed by the bottom 5 of the bunker 3 and the shield 9, which prevents the leaves from squeezing on brush 2 and increases the filling of the hopper 3. 5 Il.

FIG. at

The invention relates to a machine for cleaning lawns, squares and parks.

The purpose of the invention is to increase efficiency by increasing the degree of filling of the bunker.

FIG. 1 shows a pick-up, side view} in FIG. 2 is a view A of FIG. one; in fig. 3 shows a section BB in FIG. 2; in fig. 4 shows a section B-B in FIG. 3; FIG. 5 is a section of YYD in FIG. four.

The pickup of fallen leaves contains the frame 1, on which the drive brush 2 and the hopper 3 of the tipper type are mounted. The bunker 3 has side walls 4, the bottom 5, the front 4actb of which is located above the brush 2 and has a curvilinear shape, and the discharge opening closed by a lid

6. The loading window 7 of the hopper 3 has a rectangular shape and a bottom edge 8 which fits to the brush 2. In the hopper 3, the flap is rotatably mounted in a vertical plane.

9 attached to the side walls 4. The lower part of the flap 9 adjoins the lower edge of the 8 loading window

7.Selector has a support wheel 10 and is connected to the landing gear 12 by a hinge 12.

Pickup fallen leaves work-. melts as follows.

As the picker moves along the lawn, the brush 2 rotates, picks up the leaves and throws them through the loading window 7 into the bunker 3. As the sheet accumulates in the bunker 3, the leaves abut against the flap 9 and gradually fill the bunker 3. The filling of the hopper 3 increases account of the fact that

the current 9, the bottom 5 and the walls 4 form a depression from which the leaves cannot. Scan back onto brush 2.

The leaves are drawn up above the flap 9 and do not slide onto the brush 2, since the adhesion force of the Leaves between them is greater than the force of friction of the leaves on the bottom 5 of the hopper 3. After filling the hopper 3, the pick-up is moved to the transport position, move and unload the collected sheet through the discharge window with shifted cap 6 into the container.

Turning the flap 9 in a vertical plane changes its angle of inclination depending on the properties of the leaves to be harvested.

Claims (1)

Invention Formula A fallen leaf picker containing a frame with a drive brush and a dumping bin mounted on it, having side walls, a bottom with a front part located above the brush, and a rectangular loading window whose bottom edge adheres to the brush, characterized in that to increase efficiency by increasing the degree of filling of the bunker, it is provided with a rectangular flap with a lower edge installed in the bunker and attached to its side walls with the possibility of rotation in the vertical plane, while This lower edge of the shield is pressed to the lower edge of the loading window.
