RU97591U1 - VIBRATING WORKING BODY FOR DECREASING STUMPS - Google Patents

Abstract

 Vibro-shock working body for lowering stumps, including chopping working bodies located on a shaft connected to the rotor, characterized in that it further comprises strikers having a spring connection with chopping working bodies, with ball-shock mechanisms embedded in them.

Description

The utility model relates to forestry, in particular to devices for uprooting or removing stumps.

Known writhing rotor, including a shaft with pins, which relies on supports. Central and side fangs are rigidly fixed on the shaft (see AS 1264871 USSR, MKI A01G 23/06, 10.23.86, Bull. No. 39).

The disadvantage of the prototype is a narrow scope and low efficiency of this design, high energy consumption of the process.

The utility model solves the problem of expanding the technological capabilities of the working body and increasing the efficiency of stump removal.

This is achieved by the fact that the vibro-shock working body for lowering stumps, including chopping working bodies located on a shaft connected to the rotor, according to a utility model, contains strikers having spring connection with chopping working bodies, with ball-shock mechanisms embedded in them.

Figure 1 presents a diagram of the proposed working body, General view; figure 2 is the same, a section along aa in figure 1.

Vibro-impacting working body consists of a rotor 1 with strikers 2, chopping working bodies 3, equipped with arched grooves 4 to accommodate a movable load in the form of a ball 5. Chopping working bodies have cutters 6 and are attached to the rotor on hinges 7. The rotor is connected to the cutting working body by a spring suspension 8. The drive vibroshock working body through the shaft 9.

The work of the described working body is as follows.

The rotor 1 rotates along the arrow "a" and at the same time rotates around a central axis. Chopping working bodies 3 with cutters 6, connected with the rotor 1 by hinges 7, rotate together with the rotor. A certain preload of the springs 10 between the striker and the chopping body provides a gap that excludes striking strikers on the chopping body.

When a vibro-impacting working body meets a stump, a multi-stage chopping effect occurs. At the first stage, the impact of the cutter 6 of the chopping organ 3 on the wood. At the second stage, the ball 5 under the influence of inertia and its own mass moves along the arcuate groove 4 and makes a dynamic blow to the body of the chopping organ 3 with the cutter 6. At the third stage, the chopping organ 3 experiences a blow from the stubborn hammer 2, catching up with the chopping organ when the rotor rotates 1. Due to the fact that when the rotor rotates, the spring 10 contracts and the gap between the striker 2 and the chopping organ 3 disappears, at the fourth stage, the striker begins to inflict frequent blows on the chopping organ. In the case of frequent strokes during the contact time of the chopping organ with the stump, the rotor-chopping organ system operates in vibration-shock mode. As soon as the chopping organ with the cutter comes out of contact with the stump, it occupies its original position - it is pressed by spring 10 from the striker 2 and no blows are applied to it. Ball 5 moves in the opposite direction and becomes in the position of energy storage for a new strike. Then the next chopping organ enters the work and the process repeats.

The proposed design of the working body allows you to simply and effectively carry out vibro-impact crushing of stumps by the working body, characteristic of continuous machines.
