The utility model relates to the technical field of drilling tool stabilizers, in particular to a drill column stabilizer for drilling engineering, which comprises a drill rod, a lantern ring fixedly arranged on a group of drill rods close to a drill collar, a plurality of groups of paddles fixedly arranged on the lantern ring at intervals along the circumferential direction, an outer cylinder sleeved on the drill rod, a slurry discharge hole arranged in the outer cylinder, and the lantern ring positioned in the slurry discharge hole. According to the device, the lantern ring and the outer cylinder are installed on the portion, close to the drill collar, of the drill rod, so that when the drill rod rotates, the paddles on the lantern ring are driven to rotate, then residue soil in the slurry discharging holes is pushed upwards, and the residue discharging effect is improved.

The invention relates to the technical field of building punching equipment, in particular to a lifting type punching device for high-altitude drilling, which comprises a base, four rollers are arranged on the lower side of the base, a supporting pipe is fixedly mounted in the center of the upper end face of the base, a sliding rod is slidably mounted on the inner wall of the supporting pipe, and the sections of the supporting pipe and the sliding rod are rectangular. The electric drill is arranged on the supporting rod, accurate lifting of the electric drill in the vertical direction is achieved by means of sliding connection between the sliding rod and the supporting pipe and stable thrust provided by the feeding unit, the percent of pass of follow-up anchor bolt installation is further improved, meanwhile, the electric drill is arranged on the supporting rod in a sliding mode, and meanwhile the machining efficiency is improved. Four rollers are arranged on the lower side of the base of the device, so that the transfer efficiency of the device is improved, the working efficiency is improved, the labor intensity is reduced, a storage battery is adopted as a power supply, the complexity of continuously changing the power supply wiring position in the working process is avoided, and the safety risk of operators is further reduced.

This invention relates to a starch preparation device with an automatic rinsing function, belonging to the field of starch production technology. The device includes: a bubble washer, a screw feeder, a first mesh belt conveyor, a second mesh belt conveyor, a storage tank, and a high-pressure water washer. The screw feeder is installed at one end of the bubble washer. Both the first and second mesh belt conveyors are installed inside the bubble washer, with one end of the second mesh belt conveyor extending to the outside of the bubble washer. The storage tank is located below the second mesh belt conveyor. The chain conveyor and the perforated scum removal mechanism work together to circulate and filter out floating scum, covering the entire water surface of the bubble washer and solving the problem of poor scum removal efficiency in existing starch preparation devices with scum removal functions.
