Drilling bucket type pile digging device

Abstract

The invention relates to pile digging equipment, in particular to a drilling bucket type pile digging device. A rotating motor is connected with a vertically-downward rotating rod through an internally-arranged rotary oil cylinder, the lower end of the rotating rod is connected with a drilling bucket, a drill pipe which vertically penetrates through the drilling bucket is arranged in the drilling bucket, the upper end of the drill pipe is connected with the lower end of the rotating rod, the lower end of the drill pipe extends to the bottom of the drilling bucket, the lower end of the drill pipe is fixed to the inner wall of the drilling bucket through a fixing cross rod, the edge of the lower end of the inner wall of the drilling bucket is connected with two soil drilling blades in a hinged mode, the side edge of each soil drilling blade is provided with a clamping hole, and the lower end of the drill pipe is provided with a clamping control mechanism matched with the clamping holes. According to the drilling bucket type pile digging device, through scientific and reasonable structural connection, opening and closing of a drilling bucket opening can be easily and conveniently controlled through hydraulic control, therefore, the piling and soil digging efficiency is high, and the effect is good; in addition, the device can be controlled by a single person without needing cooperative work of many persons, the construction cost is reduced while the efficiency is improved, and a wide market prospect and the popularization significance are achieved.

Description

technical field [0001] The invention relates to pile digging equipment, in particular to a drilling bucket type pile digging device. Background technique [0002] Manually excavated piles are also called "artificial hole piles", which refer to the foundation construction of houses, bridges and other projects. Due to the needs of pile formation, the pile foundation is excavated by manpower according to the design and needs to be poured with reinforced concrete below the ground. The process of spatial location. Manual excavation of piles is suitable for pile foundations with a diameter of more than 1m. Drilled piles or flush piles should be used for piles with a diameter of less than 1m. Pile driving and pile digging are the most common construction techniques in the construction industry. The first step in building a building is to dig pile holes on the ground and carry out piling. Traditionally, especially in rural construction, the most common thing is to drill pile hole...

AI Technical Summary

Problems solved by technology

Traditionally, especially in rural construction, the most common thing is to drill pile holes with a diameter of less than one meter and a depth of about five meters. It is very difficult to drill pile holes manually, and only excavators can be used to drill piles. Pile flushing is used to deal with pile holes. Large-scale excavators are required to drill piles. Large-scale excavators are not only extremely inconvenient to transport, but also very expensive. They are not suitable for household use in rural house construction. Therefore, a A small excavator can drive the pile-drilling device. The traditional pile-drilling device uses a spiral drill bit. After directly drilling into the ground, because the soil is relatively humid, the spiral blade surface increases the soil attachment area virtually. As a result, the adhesion is increased, and it is difficult to remove the ground. Every time the excavator needs to be started to extract the auger bit, and the soil and sand between the helical blades are manually desilted, which is not only time-consuming and laborious, but also causes the labor of many people. Loss and waste, high cost and extremely inconvenient, it is difficult to achieve the effect of saving time and cost
