Abstract
The utility model discloses an ox horn excavator. An excavating head is an arc-shaped rod with a small front end and a big rear end, and the front width and the rear width of the arc-shaped rod is consistent. The rear end of the excavating head is installed on a rotary connecting head. As the ox horn excavator adopts the arc-shaped rod with the small front end and the big rear end and the front width and the rear width of the arc-shaped rod is consistent, the ox horn excavator is suitable for excavating narrow grooves on the hard ground. The problems of low efficiency, slow progress, existing personal safety hidden troubles and being limited by the width of the excavated grooves existing in the manual excavation and the excavation of the traditional excavator are solved. The excavation of the ox horn excavator is not limited by time and geology, the efficiency of construction is increased, the personal safety hidden troubles are reduced, the construction environment is greatly protected, the construction progress is accelerated, and the overall plan requirement of the groove construction is met.
Description
Technical field
The utility model relates to a kind of excavator, relates in particular to a kind of ox horn excavator that is fit to narrow type groove construction.
Background technology
In the work transmission line grounding construction process, when adopting tradition machinery to excavate such as excavator, to the damage area increase, particularly highlands of vegetation, ecological environment is relatively more fragile, is difficult to behind the vegetation deterioration recover, and causes environmental disruption and soil erosion.
And the transmission line construction engineering of some special road section, its execution conditions very severe, such as the DC power transmission line engineering in the Qinghai-Tibet Platean construction, if during March to May, construct, weather anomaly is cold, dry, anoxic is extremely serious, this moment, surperficial frozen soil layer was in frozen state, soil body hardness is large, can't adopt hand excavation's mode to carry out the ground connection channel excavation, adopt traditional common excavator to carry out the ground connection channel excavation, machinery falls effect seriously, construction speed is slow, can't satisfy the construction speed needs.
Not yet there is at present special excavator for groove construction to be documented in patent documentation or non-patent literature, also do not use precedent.
Summary of the invention
The purpose of this utility model just is to provide in order to address the above problem a kind of ox horn excavator of suitable narrow type groove construction.
The utility model is achieved through the following technical solutions above-mentioned purpose:
Mining head described in the utility model is that front end is little, the rear end large and the consistent bow of front and back width, and the rear end of described mining head is installed on the described rotary connecting joint.
Particularly, the width of described mining head is less than 0.5m.
As preferably, described mining head comprises bow matrix and working head, the rear end of described bow matrix is installed on the described rotary connecting joint, described working head front end is little, the rear end is large, the rear portion of described working head is hollow structure and is provided with opening in the rear end that the rear sleeve of described working head is contained in the front end of described bow matrix and is fixedly connected with by screw rod.The effect of working head is and can changes, and after working head may wear to a certain degree, only needs to change working head, and need not change mining head, can save cost.
Further, the middle part of described bow matrix is equipped with the loss prevention housing by screw rod, and described loss prevention housing is positioned at a side that is the indent arc on the described bow matrix.The effect of loss prevention housing is and can changes.
The beneficial effects of the utility model are:
Ox horn excavator described in the utility model adopts front end little; large and the consistent bow of front and back width in rear end; be fit to narrow type groove is excavated on the hard ground of geology; the efficient that has solved the existence of hand excavation or traditional excavator excavation is low; progress is slow; personal safety hidden danger is arranged; be subjected to the problem of trench well width restriction; the excavation work of ox horn excavator described in the utility model is not subjected to the time; geological constraints; improved efficiency of construction; reduced the life potential safety hazard; better protected construction environment; and accelerated construction speed, satisfy groove construction overall planning requirement.
Description of drawings
Fig. 1 is the perspective view of mining head, rotary connecting joint and the working arm of ox horn excavator described in the utility model.
Fig. 2 is the perspective view of mining head, rotary connecting joint and the working arm of ox horn excavator described in the utility model when in running order.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, mining head described in the utility model comprises bow matrix 4, working head 6 and loss prevention housing 5, the rear end of bow matrix 4 is installed on the rotary connecting joint 3, working head 6 front ends are little, the rear end is large, the rear portion of working head 6 is hollow structure and is provided with the opening (not shown) in the rear end that the rear sleeve of working head 6 is contained in the front end of bow matrix 4 and is fixedly connected with by screw rod 7; Loss prevention housing 5 is installed on the middle part of bow matrix 4 by screw rod 7, and loss prevention housing 5 is positioned at a side that is the indent arc on the bow matrix 4.Bow matrix 4, working head 6 and the loss prevention housing 5 common mining heads (unmarked among the figure) that form, whole mining head is that front end is little, the rear end large and the consistent bow of front and back width; The width of mining head is less than 0.5m.One side of rotary connecting joint 3 (upside among the figure) rotation is installed on the fixed arm 1, and the opposite side of rotary connecting joint 3 (downside among the figure) rotation is installed on the lever arm 2, fixed arm 1 and the lever arm 2 common working arms that form.
As shown in Figure 2, during work, the operation excavator stretches out or retraction lever arm 2, thereby control bow matrix 4 cooperates moving up and down of whole working arm simultaneously take its rear end as center of circle rotation, finishes the excavation work of groove.
