Abstract

FIELD: forest industry. The purpose of the invention is to reduce traction resistance. The working unit of the uplifter contains inclined struts and a horizontal knife 2 with removable blades (SL) 4. On the lower edge of the SL, an angular longitudinal groove 8 is made. The plane 11 is inclined to the lower edge 9 at an angle of 6–8 ° C and is aligned with the corresponding plane 12 knives and racks. The length of SL 4 of the knife 2 exceeds the distance between the SL racks. SL of inclined racks cut off lateral roots, and SL of horizontal knife central roots mon. Increasing the angle of inclination of the plane of the recess to the lower face leads to an increase in the width of the SL. Overhang of wood residues in the joints between the SL struts and the knife is excluded. 1 hp f-ly, 3 ill. A-A (Q (L Shch 1 10 Fig. Z oo CX) o o 4

Description

The invention relates to machines for the forest industry and can be used in pickups for harvesting rows of stumps, bushes, etc. for leoenergy.

The purpose of the invention is to reduce traction resistance.

FIG. 1 shows the working body of the upravel, side view; in fig. 2 - the same plan view; in fig. 3 is a section A-A in FIG. 2

The working body of the picker contains

racks 1 and 3 to perform the blade 4 with a greater length and eliminate the gaps in the joints of the racks 1 and 3 and the horizontal knife 2.

During the operation of the pruning plant, its working body of the upholster is detachable with 4 blades 4 inclined stands 1 and 3, the lateral roots of the stumps are cut along with the layer of soil. The removable blade 4 of the horizontal knife 2 at the depth of 40–60 cm rooting cut the central roots of a mon. With further 10 mixing, the working body of the cropped stump enters the writhing ribs 5 and

the left rack 1, the horizontal knife 2, with the right stump is removed on the daytime top rack 3, removable blades 4. On the horizontal of the curved strip. Soil passes

The horizontal knife 2 is positioned between the writhing ribs 5, and the ribs 5 remain. The removable blades 4 are on the uprights 1 15 of the subsoil gutter. The protruders behind and 3 and the horizontal knife 2 are fixed to the hanger of 16 removable blades 4 racks 1 and 3 using bolts 6 with a countersunk head and knife 2 in the places of their joints twice with straighteners 7. cut the roots of stumps and thereby eliminate

their overhang on the joints.

Reducing the frontal cross-section of the uprights 1 The working body of the uplifter allows

and 3 and a horizontal knife, together with the knife, to reduce its traction resistance by 48 ° / o with removable removable blades 4, by reducing the frontal section of the blade by performing a longitudinal angle of the body,

The blades 8 on the bottom edge 9 of the blades 4 and the open groove 10 on the planes of the studs 1 and 3 and the knife 2. The inclination of the plane 11 of the angular recess 8 to the bottom edge 9 of the removable blade 4 is made at an angle of 6-8 °. The plane 11 of the recess 8 and the plane 12 of the groove 10 form mating surfaces. The cut of bolts 6 excluded the second flat formula of the invention

Claims (2)

1. The working body of the uplifter, made in the form of racks and a horizontal knife with removable blades arranged at an angle to the horizon, characterized in that, in order to reduce the drag resistance of the recess 13 and the frontal plane, on the removable knife blades and racks the bone 14 of the knife 2 and racks 1 and 3. The offset of the removable blades 4 along the open groove 10 on the inclined racks 1 and 3 and the cut of the fastening bolts 6 is limited by the stops 15 fixed to the planes of the racks 1 and 3. The end sections of the removable blades 4 35 are provided with shoulders 16. This allows, with a smaller distance between the blades an angular longitudinal groove is made; one of the planes of which is inclined to the lower edge of the blade at an angle of 6–8 ° and is associated with the corresponding plane of the knife and racks. 2. A working member according to claim 1, characterized in that the length of the removable blade of the knife exceeds the distance between the blades of the arms. racks 1 and 3 to perform the blade 4 with a greater length and eliminate the gaps in the joints of the racks 1 and 3 and the horizontal knife 2. During the operation of the pruning plant, its working body of the upholster is detachable with 4 blades 4 inclined stands 1 and 3, the lateral roots of the stumps are cut along with the layer of soil. The removable blade 4 of the horizontal knife 2 at the depth of 40–60 cm rooting cut the central roots of a mon. With further mixing, by the working body, the cropped stump enters the writhing ribs 5 and Invention Formula 1. The working body of the uplifter, made in the form of racks and a horizontal knife with removable blades arranged at an angle to the horizon, characterized in that, in order to reduce traction, an angular longitudinal recess is made of one of the planes of which is inclined to the lower edge of the blade at an angle of 6- 8 ° and is mated to the corresponding plane of the knife and racks. 2. A working member according to claim 1, characterized in that the length of the removable blade of the knife exceeds the distance between the blades of the struts. Fy Fig .. 2
