The present invention relates to the technical field of soil remediation, and in particular to a soil screening device for soil remediation that can avoid soil accumulation. Its technical solution includes: a screening device main body and a feed hopper provided on the top of the screening device main body, a preliminary screening mechanism is provided in the screening device main body, the preliminary screening mechanism includes a crushing roller assembly and a beating roller rotatably installed in the screening device main body, the crushing roller assembly is located above the beating roller, the preliminary screening mechanism also includes a driving assembly fixedly installed outside the screening device main body for driving the crushing roller assembly and the beating roller to rotate, and the screening device main body is also provided with an anti-accumulation mechanism located below the preliminary screening mechanism. The present invention can avoid the conditions for soil accumulation and agglomeration through this multi-step refinement process, thereby ensuring the improvement of the effect of soil remediation.

The utility model discloses an anti-skid wear material spreader for pavement maintenance, which relates to the technical field of pavement maintenance and comprises a transport vehicle, the top of the transport vehicle is rotatably connected with a carriage through a hinge, the bottom of the carriage is fixedly connected with a spreading pipe on one side of the transport vehicle, and the outer side of the spreading pipe is sleeved with a discharge pipe. The discharging pipe is rotationally connected with the spreading pipe, two adjusting plates are rotationally connected into the discharging pipe, and an adjuster is installed on one side of the discharging pipe. Compared with the prior art, the anti-skid wear material spreader for pavement maintenance has the beneficial effects that the rotary discharge pipe sleeved outside the spreading pipe is matched with the connection of one end of the adjusting rod on the turntable and the discharge pipe, so that the adjusting rod can drive the discharge pipe to swing repeatedly along with the rotation of the turntable, the discharge of materials is accelerated, the blockage is prevented, and the service life of the spreading pipe is prolonged. And the adjusting plate in the discharging pipe rotates under the action of the worm gear set and the worm set, so that the angle of the adjusting plate and the distance between one end of the adjusting plate are conveniently adjusted, and the discharging range is controlled.

The invention relates to the technical field of construction dust falling, in particular to an energy-saving rainwater dust falling device for construction, rainwater falling during raining can be collected through a water collecting hopper, and the collected rainwater can downwards flow into a water spraying plate to be stored for being sprayed out by an atomizing nozzle for dust falling, so that the rainwater can be collected and stored as a raw material for dust falling; meanwhile, the mounting groove or the mounting base is connected with an external tap water pipe, so that the external tap water pipe can pump water into the water sprinkling pipe, when the tap water reaches the interior of the water sprinkling pipe, the tap water can fall down through the separation net to form a water curtain, the dust separation effect can be achieved through the water curtain, and the dust falling effect can be further improved; the tap water forming the water curtain can fall down into the water collecting hopper and then flow into the water spraying plate to be stored for being sprayed out by the atomizing nozzle, so that the tap water can be used for the second time, the tap water is saved, the dust falling effect is improved, and the utilization rate of resources can be increased.
