Description

one

The invention relates to the agricultural machine building and can be used in the construction of power stand equipment (for example, a tractor) mounted on the road sweepers and hoppers.

The purpose of the invention is to increase the productivity and reduce the loss of haylong mass.

In Fig.1 schematically shows a stacker-loader, side view, in Fig, 2 - the same, top view. .

The stacker-loader consists of frame 1, rake grid 2, pushing wall 3, grippers 4 made of pipes with a constantly decreasing cross-sectional area. from the bases to the tops and tapering at the ends. The base grippers 4 are rigidly connected with vertical axles 5, the pins of which are pivotally connected to frame 1 in the upper and lower parts. The grips 4 in the horizontal plane are bent inward at the level of the fingers of the rake grate 2. For a more complete mass collection, the lower fingers of the grippers have a tooth b, which can be straight or bent in the direction of movement of the stack-loader when the weight is swallowing. They are set by the lower ends at or below the level of the soil surface. The grippers 4 are driven by the hydraulic cylinder 7 through the arms 8 rigidly connected to the axis 5. The closed state on both sides of the arms 4 are set symmetrically with respect to the rake grid 2 by the stops 9 fixed on the frame 1, which is connected to the lifting hinge lever, boom 10. I

Tooth 6 is advisable to install when swathing grass or straw rolls, as well as to collect hay or straw on the hayloft. 5 The grippers 4 can be driven by one or two hydraulic cylinders connected to the tractor's hydraulic system (not shown) in parallel. To drive the pushing wall 3, hydraulic cylinders (not shown) are provided, the connection of which with the hydraulic cylinders dp of the drive of the grippers 4 should ensure that the steel wall 15 can only move after fully opening the grippers 4.

The device works as follows.

20 Before collecting the mass with a hydro-spindle 7, the grippers 4 are diluted to the sides (figure 2), the frame 1 is moved forward, and the rake 2 is installed on the soil surface. After filling 25 the stacker-loader with the weight of the grippers 4 by the hydraulic cylinder 7 is inwardly compressed. Curved ends of the fingers of the grippers 4, forming the front wall in the form

30 lattices, close the collected mass volume on the rake lattice 2 from the sides and front. In this position, the frame 1 is raised and delivered to the place of discharge.

When the tractor is unloaded by the hydraulic system of the tractor, the oil pressure is supplied to the working bodies of the stacker-loader. In this case, the claws 4 are divorced to the sides by the hydraulic cylinder 7, after which the weight is pushed off the rake grid 2 by the colliding wall 3.

Claims (1)

STOGOMETATEL-LOADER, comprising a frame mounted on a hinged boom, on which a rake lattice, a colliding wall and a rotary gripping body are installed, characterized in that, in order to increase productivity and reduce losses of senosolomic mass, the gripping body is made in the form of two swivels around vertical axes of palm lateral grips, the ends of the fingers of which are pointed and bent towards the fingers of the rake lattice, and the grippers are equipped with teeth, the upper ends of which are fixed to izhnih finger grip. .SU-.1205814>
