Description

The invention is designed to work in the field of construction and can be used to loosen the soil when operating machines with a controlled working body.

A known mechanism for controlling the working body of the machine for loosening the ground, comprising a body having a hinge assembly for connection with the frame of the machine, a gear rack located inside the body. The end of which protrudes from the housing, which has an image of a hinge assembly for connection with the machine guide, and the assembly

fixing the rack.

A disadvantage of the known mechanism is the inability to adjust the angular deviation of the guide of the working member at the beginning of work to set it at the required angle, which will make it impossible to drop the working member at an angle to the ground surface,

The purpose of the invention is to provide adjustment of the angle of inclination of the guide pa ... of the barrel organ to increase the efficiency of loosening the soil.

The goal is achieved in that the casing is installed with the possibility of forced movement in the axial direction by a hydraulic cylinder, for example, a double action, one end of which is pivotally connected to it, and the other has a hinge assembly for connection to the machine frame, while the casing is made with respect to the hinge assembly, which connects the frame to the frame of the machine.

The drawing shows a machine for loosening the soil, a general view.

Claims (1)

The machine contains a base gauge 1 with a frame, guided with 2, the upper link of which is connected to the boom of the frame (not shown) with the working body 3. The operating mechanism 3 includes a housing 4 having a hinge 1 Gatch 1, a rail 6 inside the casing 4, the end of which protrudes from the casing contains a ball-shaped knot for connection with the guide 2: The knot includes a cup 7 with horizontal grooves 8 in which the fingers 9 of the slats are fixed. In the cup 7, a shock absorber is installed. Eugin 10. The fixing unit of the toothed rack 6 is made of a shaft 11c with a fixed gear fixed on it (not shown), which constantly engages the toothed rack 6 teeth and the locking disks 12, and the discs 12 are made from a gear wheel, forming a 13-hp pair with a lever, or can be made from a drum covered by a sp (j) tapes. The locking discs 12 are controlled by a hydrocyteshaft 14, the casing of which is connected by a hinge 15 to the casing 4 of the toothed rack 6, and the rod is connected by the lever system 16 of the ratchet pair. The housing 4 is installed with the possibility of forcibly moving in the axial direction the hydrocyte of the dual action leader 17, one of which has a hinge 18 CBsoaH with the housing 4, and the other has a hinge assembly 19 for connecting to the traction frame 1. In this case, the longitudinal grooves 20 are made in the housing 4 for its movement relative to the wellbore of the site 5, connecting the body 4 with the frame t gacha. 1. The device works as follows Before raising the worker. The body 3 engages the discs 12. Through the hydraulic cylinder 14 and the lever system 16, fixing the guide 2 in the initial position. After that, the hydraulic cylinder 17 moves the body 4 with the guide 2, and installs the kotfu under the necessary flap. Then the working body 3 is pushed to a predetermined height and dropped on the ground. During its movement in the ground, the actuator acts on the guide 2 which in turn moves the toothed rack 6 through the damping 1 body 10 in the body 4. The rail 6 rotates the shaft 11s through the gear wheel 12, the end position of which is fixed by the ratchet pair. Thus, the attachment is fixed after each strike in a position that ensures that the working body is in place at the end of the previous strike. After a series of blows is applied to the ground and its loose hydraulic cylinder 14, it acts on the lever 13, disengaging the discs 12. The guide 2 under the action of the horizontal component of its weight and the weight of the working body returns to a vertical position when lifting, moving the rail 6 in the housing 4. The machine is then transferred to a new pose and the cycle repeats. Claims The mechanism for controlling the working body of a soil loosening machine, comprising a housing having a hinge assembly for connection with a mashine frame, a rack and rail located inside the housing; protruding from the housing, the end of which has a hinge assembly for connection with the tool carrier guide, and a gear rack fixation unit, characterized in that the housing is installed with the possibility of adjusting the inclination angle of the guide train carrier to increase the soil loosening strength. Axially, it is supplied by a hydraulic cylinder, for example, of double action, one end of which is hingedly connected to it, and the other has a hinge assembly for connection to the frame of the machine, while Longitudinal grooves for its relatively peremegieni hinge assembly communication PS & anlpego housing with the machine frame. 19 17 18
