The overall structure of the wire clamp is reasonable, the operations of hanging and removing a grounding wire are simple, the wire can be effectively clamped, the labor intensity of workers is reduced, and the work efficiency is improved.

The invention relates to the field of building construction, and particularly discloses a reinforced concrete waste treatment device which comprises a crushing box. A coarse crusher is arranged in thecrushing box, an obliquely-arranged sliding way is fixed to the output end of the coarse crusher, and a crushing device is arranged at the lowest end of the sliding way and comprises two crushing rollers arranged in parallel; the crushing rollers are rotationally connected to the inner wall of the crushing box, the two crushing rollers rotate oppositely, a plurality of crushing thorns are distributed on the surfaces of the crushing rollers, and the crushing thorns of the adjacent crushing rollers are alternately distributed; a first conveying belt is fixed below the crushing rollers, a separation roller is arranged above the first conveying belt, the length of the separation roller is equal to the width of the first conveying belt, the separation roller is rotationally connected to the inner wall of the crushing box, and a plurality of staggered claws are fixed to the upper surface of the separation roller and make contact with the first conveying belt; and a second conveying belt which is obliquely arranged is fixed obliquely below the separation roller. The reinforced concrete waste treatment device aims to solve the problem of separation of steel bars and concrete in reinforcedconcrete waste.

The invention provides an environment-friendly soil remediation method. A fixed base, a rotating motor, a rotating frame, cubing devices, a lifting air cylinder, a circular cover group, two working devices and two partitioning devices cooperate to complete soil remediation operation. The environment-friendly soil remediation method can solve the problems that it is difficult for a worker to completely rake out plastic bags or flexible sheet objects by using an existing rake, and surfaces of the raked-out plastic bags or flexible sheet objects have a small amount of clay due to the conditions that the viscidity of the clay is relatively high, and the plastic bags or flexible sheet objects and the clay are stuck to each other to result in that the raked-out plastic bags or flexible sheet objects are still stuck to the existing rake, and need to be manually separated by the worker, the separation process is slow, and the like.

The invention belongs to the technical field of non-woven fabric production, and particularly relates to a drum-type leftover material recovery device for non-woven fabric production. The drum-type leftover material recovery device comprises a cylindrical shell, a feeding hole is formed in the upper end of the cylindrical shell, and a crushing drum is arranged in the cylindrical shell in the axisdirection of the cylindrical shell; a plurality of crushing blades are installed on the outer side wall of the crushing drum and the inner side wall of the cylindrical shell at equal intervals, the multiple crushing blades are spirally arranged in a staggered manner, a driving motor is arranged above the cylindrical shell and connected with the crushing drum through a driving mechanism, and a collecting groove is rotatably connected to the bottom of the cylindrical shell; and a conveying belt is arranged in the collecting groove. By means of relative rotation of the crushing drum and the cylindrical shell, non-woven fabric is cut and crushed, the crushing effect is better, crushed non-woven fabric fragments can be screened and cut multiple times, the recycling requirement of the non-wovenfabric is met, a crushing device does not need to be adjusted or replaced, and the product quality and the working efficiency are greatly improved.

The invention relates to the technical field of automobile hooks and discloses an automatic ejection hook for an electric automobile. The automatic ejection hook comprises a thermal bimetallic plate;in a state of vehicle spontaneous combustion, the thermal bimetallic plate is heated to bend rightwards to push a trigger rod to move rightwards; the trigger rod moves rightwards to be inserted into apressing groove; a locking rod is pushed to move downwards under the action of the inclined surface of the inner bottom wall of the pressing groove; the locking rod moves downwards to drive a protruding part to move downwards. The locking of the projection part on the ejection block is relieved; at the moment, the ejection block impacts rightwards under the action of the elastic force of an ejection spring; a punching rod is driven to impact rightwards; a movable block and a hook are ejected out, a firefighter can hook the hook conveniently, then the spontaneous combustion vehicle is draggedaway more conveniently, the trailer is more convenient, the safety of the trailer is improved, and economic losses are reduced; the design is novel, the structure is simple, operation is easy, and theadvantage that the trailer hook can be ejected automatically when the vehicle spontaneously combusts is achieved.

Most fishing parks are located in a mountainous area or in the field, in such places, much grass and many shrubs exist, a large number of winged insects, mosquitoes and flies and moth move, fishy-smell bait also attracts the organisms easily, the organisms can easily spread diseases and bring trouble to fishing fans, and the fishing fans cannot enjoy fishing.
