A rotary cutting coring device for rapidly excavating mine pits on hard ground

Abstract

The invention discloses a rotating, cutting and coring device capable of rapidly digging a landmine pit in hard ground. The rotating, cutting and coring device comprises a sleeve and a mounting plate fixedly connected with the sleeve, wherein transverse cutting devices circumferentially distributed are mounted on the sleeve, the transverse cutting devices comprise linkage shafts and transverse cutting blades, the upper ends of the linkage shafts are fixedly connected with driving levers, the driving levers are hinged to electric push-pull rods, the electric push-pull rods are mounted on the mounting plate, the lower ends of the linkage shafts are fixedly connected with the transverse cutting blades, an annular saw-toothed drill bit is mounted at the lower end of the sleeve, the mounting plate is fixedly connected with a connecting drill rod, the connecting drill rod is connected with a power mechanism, and the power mechanism is fixed to a carrying plate. First, a round cut opening is formed by cutting the ground through the annular saw-toothed drill bit, then, a core body is cut through the transverse cutting blades, the core body is taken out by driving a cylinder to move through an electric lifting rod, a disguise layer and waste residues on the ground surface are perfectly kept and wholy lifted above the ground, and the basic requirement of a landmine pit digging standard is met.

Description

technical field [0001] The invention relates to a rotary cutting coring device for quickly excavating a mine pit on a hard ground, which belongs to an electromechanical control excavation operation device. Background technique [0002] A mine pit usually refers to a circular flat-bottomed pit with a certain diameter and depth for laying mines. At this stage, when our army lays mines manually, excavating mine pits is done manually by individual soldiers using engineering shovels. Although manual excavation of mine pits requires less equipment and flexible organization and implementation, the excavation efficiency is low and the quality of mine pits is difficult to guarantee under hard ground conditions such as clay, frozen soil, gravel, and asphalt pavement. It is an urgent problem to develop a device that can replace manual excavation of mine pits on hard ground to improve operating efficiency and quality. Compared with manual work, mechanical devices can better solve the ...

Problems solved by technology

[0006] Disadvantages of manual work: On hard ground, the speed of excavating mine pits is slow and the efficiency is low. Simple tools such as shovels and picks excavate mine pits with irregular shapes, inaccurate sizes, and inconsistent specifications, which cannot be completely preserved. surface camouflage layer

[0007] Disadvantages of the auger rod type pit digging machine: the top of the drill bit of the auger rod type pit digging machine is tapered at a large angle, and the bottom of the excavated pit is funnel-shaped, which cannot meet the requirements of a flat bottom

During the excavation process, the auger drill pipe cuts and throws the soil, which cannot completely preserve the surface camouflage layer and collect waste residue, which is not conducive to camouflage in the minefield area

[0008] Disadvantages of the core drilling machine: After the core drilling machine digs to the predetermined depth, the bottom of the cut and formed columnar core is not broken, and it is necessary to manually use a special tool to break and take out the core from the pit. The bottom section of the pit is determined by shearing Formed by breaking due to force, it is impossible to ensure that the bottom of the pit is flat, and the degree of automation is not high, which affects the operation efficiency
