Abstract

The utility model discloses a drilling component of a digging machine for the pit shape land preparation and the hole digging of afforestation building. The utility model comprises a drill tip, a drill rod, a spiral sheet and a knife row. The utility model is characterized in that a work edge of a knife row plate forms an equal spiral line shape; a knife blade of the knife row plate forms an arc shape. In the working process, the knife row has transverse cutting function and also has cutting function on soil layers and grass roots. The earth loosening effect is good, the utility model is not easily wound by grass roots, the hole digging efficiency is improved, and the utility model is favorable for reducing the vibration of the machine.

Description

A kind of drill set component of hole digger

The utility model belongs to a kind of drill set component, is specifically related to a kind of drilling tool of the excavation facility that are used to build forest hole type soil preparation and dig pit.

The drill set component of existing hole digger, mainly the flight that distributes by apex point, drilling rod and round drilling rod and two groups of blade rows that are installed on about the flight end constitute.This drilling tool is in operation process, collection boring, loosen the soil and stirring action in one, comparatively ideal effect is arranged for digging pit wholely, but because existing hole digger drill set component, the blade row system of playing loosening function adopts work edge linearly the blade row plate and the blade of type, when blade row loosens the soil, only utilized the active force of transverse direction, its weak effect that loosens the soil, simultaneously, soil layer is also bigger to the active force of blade row, and more serious problem is that the joint portion of blade row plate and blade also often is subjected to the winding of grass roots easily, increasing is to advancing the influence of drilling speed degree, vibrations are jolted and are also increased thereupon, and the user has to stop when serious, carry away could continue to use after drilling tool is removed the grass roots that twines.

The purpose of this utility model is to overcome above-mentioned deficiency and a kind of drill set component is provided, and this drill set component can be eliminated the problem that grass roots twines blade row effectively, also has better effect simultaneously for loosening the soil.

The utility model is realized by following scheme: this drill set component comprises apex point, drilling rod and the flight that distributes round drilling rod and be installed on two groups of blade rows about the flight end, wherein, blade row comprises blade row plate and some blades, be characterized in that the work edge of blade row plate is made into etc. and advances scroll; The work edge of blade is made into arc.

Drill set component of the present utility model, because being respectively etc., blade row plate and blade work sword advance scroll and arc, make drilling tool in the course of the work, blade row is except the effect that possesses crosscut, soil layer and grass roots also had the effect of cutting, it loosens the soil effective, especially for grass roots, because the arc work edge of blade advances cooperating of scroll work edge with the grade of blade row plate, make its joint portion not stay the dead angle, the grass roots that twines can be cut off, guaranteed further creeping into of drilling tool, improve the efficient of digging pit, and helped alleviating the vibrations of facility.

Fig. 1 is a kind of concrete enforcement structure chart of the utility model;

Fig. 2 is the left blade row structure chart of Fig. 1;

Fig. 3 is the right blade row structure chart of Fig. 1.

The utility model is described in further detail below in conjunction with accompanying drawing:

With reference to Fig. 1, Fig. 2 and Fig. 3, this drill set component comprises apex point 1; Drilling rod 2; Be the axle center with the drilling rod, around the drilling rod fixing flight 3 that distributes; And be installed on left and right blade row 4 about the flight end, wherein, blade row 4 comprises blade row plate 41 and some blades 42, and the work edge 412 of blade row plate 41 is made etc. and to be advanced scroll, the work edge 421 of blade 42 is made arc, and blade 42 is fixed on the blade row plate 41 by soldering.Consider in the process of digging pit, need pulverization preferably for sandstone harder in the soil property, two groups of fixing blades preferably are and are in staggered distribution on the left and right blade row plate, are beneficial at diverse location sandstone be pulverized, and can obtain better effect.

Claims

1. the drill set component of a hole digger, the flight that comprises apex point, drilling rod and distribute round drilling rod and be loaded on two groups of blade rows about the flight end, wherein, blade row comprises blade row plate and some blades, it is characterized in that, the work edge of described blade row plate is etc. and advances spirality, and the work edge of described blade is curved.

According to the drill set component of claim 1, it is characterized in that 2, the blade on described two groups of blade rows is and is in staggered distribution.
