Pot hole drilling and digging machine carried on wheel type tractor

Abstract

The invention discloses a pot hole drilling and digging machine carried on a wheel type tractor, belonging to the technical field of foundation engineering construction machinery. The wheel type tractor comprises a rear axle and a power take-off shaft. The pot hole drilling and digging machine comprises a cantilever, an oil pump, a hydraulic station, a cantilever oil cylinder, a drill lifting mechanism and a drilling and digging mechanism, wherein the lower end of the cantilever is hinged onto the rear axle; the oil pump is fixed with the rear axle and in drive connection with the power take-off shaft; the hydraulic station is fixed on the rear axle and connected with a hydraulic oil way of the oil pump; the cantilever oil cylinder is arranged on the hydraulic station, used for driving the cantilever to move and hinged with the cantilever; the drill lifting mechanism is arranged on the cantilever and connected with the hydraulic oil way of the hydraulic station; and the drilling and digging mechanism is connected with the oil way of the hydraulic station, suspended on the cantilever and joined with the drill lifting mechanism. The invention has high working efficiency, thereby guaranteeing the construction progress and also reducing the labor intensity of the construction personnel effectively.

Description

technical field [0001] The invention belongs to the technical field of foundation engineering construction machinery, and in particular relates to a pit drilling machine mounted on a wheeled tractor. Background technique [0002] The construction of poles and columns in the laying (wiring) construction of power communication lines, the construction of shallow foundation piles for buildings, well drilling and even afforestation all involve the excavation of the floor (foundation), and the excavation of the floor The technical information of the excavation device can be found in a large number of documents, especially Chinese patent documents (about 40 patents). However, in the actual construction operations mentioned above but not limited to the above mentioned, Manual excavation is still dominant, and mechanical excavation is rarely used. The applicant believes that the reason why people pay more attention to manual excavation and neglect mechanical excavation may be that t...

AI Technical Summary

Problems solved by technology

The applicant believes that the reason why people pay more attention to manual excavation and neglect mechanical excavation may be that the excavating machines in the prior art are not practical and the combat effectiveness is not strong. Digging pits, the so-called weak combat effectiveness refers to the low efficiency of digging pits

Undoubtedly, relying on manpower to dig potholes is not only inefficient, but also labor-intensive for the builders, and the progress of the project cannot be guaranteed.
