SU1559064A1 - Ripper working member - Google Patents

Abstract

The invention relates to earthmoving machinery and can be used in rippers for the development of durable soils. The goal is to increase the efficiency of loosening by allowing the repeated impact of an increasing pulse power per one drop of the working body. The device includes a wedge-shaped housing 1 with a liquid chamber (LCD) 2. In the horizontal direction, the LCD 2 is limited by spring-loaded pistons 4, and in the vertical direction by a spring-loaded piston 3. The latter is rigidly connected to the cargo block (GB) 9. The working element is connected through GB 9 with a lifting thrust 10. On the pistons x 4 the sliding shear teeth 7 are rigidly mounted. The device is equipped with an electric generator 11 pulses with a negative electrode (E) 12 and a positive E 14 located in the LCD 2. The electric generator through limit switches 15 is connected with positive E 14. Negative E 12 is made with cumulative recesses directed toward the horizontal pistons 13. The working member is dropped from the required height, and the wedge-shaped body is inserted into the ground. Then GB 9 presses on the piston 3 and pushes the splitting teeth 7 into the ground, which form preliminary cracks in it. When GB 9 contacts the limit switches 15 between the negative and positive E 12 and 14, an electric discharge occurs. The pressure of the repeated impulse splitting the teeth 7 destroys the solid ground. The cycle is repeated. 1 il.

The invention relates to earth moving machinery and can be used in lifting and impacting rippers for developing strong soils.

The aim of the invention is to increase the efficiency of loosening due to the possibility of the repeated impact of the increasing power pulse on the chipping teeth one way of dropping the working member. The drawing shows the working body of the ripper.

The working body contains a wedge-shaped housing 1, inside of which a liquid chamber 2 is located, bounded by a vertical movable piston 3 and horizontal movable pistons 4. All pistons are spring-loaded respectively by springs 5 and 6. On the pistons x 4, the sliding scissor teeth 7 are rigidly fixed. Piston 3 by rod 8 rigidly connected to the cargo block 9, which is connected to the lifting rod 10. The device is equipped with an electric generator 11 pulses with 2 electrodes located in the liquid chamber. The negative electrode 12 is made with directional horizontal pistons 4, cumulative recesses 13, in front of which are installed the ends of the positive electrodes 14. The latter are connected to the generator 11 by means of limit switches 15 arranged to interact with the load unit.

The working body of the ripper works as follows.

When a working body falls from a certain height, a wedge-shaped body 1 is immersed in an array of frozen or solid ground. Next, a blow is struck to the body 1

With the block 9 and the compression of a fluid (for example, process water) by the piston 3. The latter causes the pistons 4 to forcibly insert splitting teeth 7 into the ground that extend beyond the wedge-shaped housing 1. Simultaneously with this process, the limit switches act 15 , which leads to the appearance of an electrical discharge in the fluid, and this creates pressure, which is transmitted to the pistons 4, thereby having an additional effect on the splitting teeth 7. In addition, the resulting pressure is transmitted to the piston 3, which lifts the cargo block 9 to a certain height. The process is then repeated until the ground is completely destroyed. The tool is then lifted using lifting rod 10, and the chipping teeth 7 are replaced by the springs 6. The cycle is repeated. Invention Formula The working body of the ripper, which includes a wedge-shaped body, inside of which there is a liquid chamber, is bounded by vertical and horizontal movable spring-loaded pistons, a sliding chipping tooth rigidly mounted on horizontal pistons, and a cargo block connected to a lifting rod and rigidly with a vertical piston, characterized by that, in order to increase the efficiency of loosening due to the possibility of the repeated impact of the increasing power pulse on the splitting teeth for one defrauing the working body, the device is equipped with an electric generator of pulses with the arrangement of 515590646 mi in the fluid chamber electrodes, the ends of the positive electrodes, and then the negative electrode of the latter is connected to the generator more fully directed towards the go-impulses by means of end off-horizontal pistons of cumulators, arranged with grooves in front of which are installed in interaction with the pear block.
