Embodiment Construction

[0025] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further elaborated below in conjunction with specific embodiments and illustrations.

[0026] Such as figure 1 As shown, an excavator for a pole hole, the main body of which is two shovel bars 1 arranged opposite to each other. The shovel bar 1 includes an upper handle 2 and a spade head 3 fixedly arranged at the lower end of the handle 2 by welding. A connection block 5 is provided on the inner surface of the top of the spade head 3, and the two spade bars 1 are flexibly connected through the connection block 5 through the screw rod 4. The bottom 7 is arc-shaped, which can be easily inserted into the soil and saves labor. The spade face 6 of the spade head 3 is rolled up on both sides and has a hollow cavity in the middle, and the top 8 of the spade face 6 is wider than the bottom. 7. It is convenient to excavat...

Abstract

The invention discloses an electric pole hole digging device and relates to the technical field of electric wire line laying equipment. The main body of the electric pole hole digging device comprise two spade rods which are symmetrically arranged on the left and the right. Each spade rod comprises a handle which is arranged at the upper part, and a spade head which is fixedly arranged at the lower end of the handle through welding. A connecting block is arranged on the internal side surface of the upper part of each spade head. The two spade rods are movably connected through a screw which penetrates through the connecting blocks. The electric pole hole digging device has the beneficial effects of convenience in carrying, high use flexibility, high quality, low cost, convenience in maintenance, rapid digging speed, small backfilling earthwork, high stability of newly erected electric poles, and remarkable economic benefit.

Description

Technical field: [0001] The invention relates to the technical field of equipment for laying electric wires, in particular to an excavator for pole holes. Background technique: [0002] Telephone poles, as the name suggests, are poles for wires. Appearing in various villages-fields-roads-streets, it was one of the important infrastructures in early China. In the construction work of line erection, the engineering volume of pole hole excavation is very huge. At present, mechanical excavation can be used for pole holes along highways, but manual excavation is mainly required for poles not along highways. Because the traditional excavation method needs to excavate a pole hole with a diameter of about 80 cm, the workload of excavation and backfilling is very large. A skilled worker can only excavate about 2 pole holes in one day, which not only seriously affects the progress of the project, but also greatly increases the excavation cost. The purpose of the patented invention...
