The invention discloses a handheld concrete drilling and coring machine. The handheld concrete drilling and coring machine is characterized by comprising a base, a drilling and coring device, a lifting device, a water tank, a liquid feeding mechanism and a liquid returning mechanism, and the base is placed at a coring position. The drilling and coring device is driven by the lifting device to move up and down to carry out drilling and coring on concrete, and when the drilling and coring device drills downwards, a bottom plate is driven by a downward pressing spring to move downwards, so that a sealing disc is tightly attached to the concrete, and water flow is prevented from overflowing; cooling water flowing out of the drilling and coring device returns to the water tank through the liquid returning mechanism, so that the problem that water resources are wasted is solved; and a suction cup is arranged in a core pipe, during coring, the suction cup is adsorbed on a core material, the core material is taken out of a drill hole, the suction cup is separated from the core material through water spraying of a water pump, the core material is prevented from being clamped in the drill hole, meanwhile, when the drilling and coring device moves upwards, the sealing disc is separated from the concrete, and therefore drilling and coring work can be conveniently carried out again, the coring process is simplified, and the coring efficiency is improved.
Description
technical field [0001] The invention relates to a hand-held concrete drilling and coring machine. Background technique [0002] Drilling and coring machines are mainly used for drilling concrete and asphalt concrete test cores, and performing compression and flexural tests. The existing hand-held drilling and coring machines are complex in structure and generate a lot of heat due to the friction between the hollow drill and the road surface , requires cooling water spraying for cooling, and the hollow drill is in a state of high-speed rotation, which will throw the cooling water to the surroundings, which is easy to throw on the surrounding staff, and wastes water resources. At the same time, when taking the core, there will be core material If it is stuck in the hole, the process of coring material is cumbersome, which affects the efficiency of coring. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hand-held...
