Problems solved by technology

Although the depth of these pile pits or tree pits is about 1 meter, which belong to shallow soil pits, the excavation work is intensive and inefficient
Although pile foundation excavation equipment is often used for foundation excavation at construction sites, the equipment has a complex structure, high cost, and the excavation depth is usually more than 3 meters. It is obviously inappropriate to dig tree pits or pile pits with such equipment

Embodiment Construction

[0014] The digging machine shown in Figure 1 is refitted on the basis of the agricultural tricycle, which maximizes the use of the frame, engine, traveling device and hydraulic device of the agricultural tricycle, which is simple and practical. low cost. The specific structure is shown in FIG. 1 , the frame 1 is provided with a traveling wheel 11 , and the lower part of the drill pipe 2 is provided with a helical blade, which is used to lift and transport the loosened soil to the ground. The drill rod drive box 3 for driving the drill rod 2 to rotate is installed on the frame 1 , and the input shaft 31 of the drill rod drive box is connected with the power device 8 . As shown in FIGS. 1 and 3 together, the power unit 8 includes an engine 81 that transmits power through a first belt drive 82 to a reduction box 83 that transmits power to the drill rod drive box 3 . In order to improve the work efficiency, the digging machine is provided with two drill rods 2, which are driven b...

Abstract

The pit digger includes one frame with traveling wheels, one drill rod with helical blades in the lower part, one drill rod driving box to rotate the drill rod, one fixing unit to fix the drill rod driving box onto the frame, one power set connected to the input shaft of the drill rod driving box, one sleeve around the upper part of the drill rod, support rods connected between the sleeve and the frame, and one drill rod elevator. The pit digger has simple structure, low cost and high operation efficiency, and may be applied widely for digging tree pit or pile hole.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a device for digging shallow pits such as tree pits and pile pits. Background technique [0002] When building a plastic greenhouse, it is necessary to pre-embed multiple rows of cement piles in the ground. Sometimes, in order to fit the structure of the arch shed, the same row of cement piles must be inclined at a certain angle. The excavation of these pile pits is mostly done manually. , the work of digging tree holes is almost the same. Although these pile pits or tree pits are about 1 meter deep and belong to shallow soil pits, the excavation work is intensive and inefficient. Although pile foundation excavation equipment is often used in the foundation excavation of construction sites, the equipment is complex in structure, high in cost, and the excavation depth is usually more than 3 meters. It is obviously not suitable to use such equipment to excavate tree...
