Crushing device for recycled concrete production

The invention discloses a crushing device for recycled concrete production. The device comprises a feeding box and a processing box, the bottom of the feeding box communicates with the left side at the top of the processing box, and a first crushing roller set is rotationally connected between the front side and the rear side of an inner cavity of the processing box through bearings. A conveying plate is rotationally connected to the top of the left side of the inner cavity of the processing box through a rotating block, and a transverse plate is fixedly connected to the position, located below the conveying plate, at the left side of the inner cavity of the processing box. The crushing device for recycled concrete production relates to the recycled concrete production technical field, after the preliminary crushing, the waste concrete is directly subjected to spray washing treatment, and the impurities are screened out, so that the treatment capacity of the device on the waste concrete can be reduced, the gaps on the surface of the waste concrete can be looser, the crushing is facilitated, and then the crushing treatment is conducted, and accordingly the crushing effect of the device on the waste concrete can be guaranteed, and the later-period reuse machining quality is guaranteed.

Low-altitude positioning load air-drop method based on multi-rotor unmanned aerial vehicle

The invention discloses a low-altitude positioning load air-drop method based on a multi-rotor unmanned aerial vehicle. The multi-rotor unmanned aerial vehicle comprises an aerial flight platform, onboard task equipment and a ground remote control device. The onboard task equipment is located below the aerial flight platform. The onboard task equipment comprises an air-drop engine, a positioning camera and a directional voice broadcast device. The method solves the problem that air-drop of badly-needed emergency supplies is difficult in emergency rescue. The multi-rotor unmanned aerial vehicle has the advantages of being low in cost, easy and convenient to operate and easy to maintain and facilitating transport; with the low-altitude hovering function of the multi-rotor unmanned aerial vehicle and the assistance of the onboard assistant task equipment such as the voice broadcast device and the positioning camera, material air-drop accuracy and utilization efficiency are improved. The method has outstanding application value for a small number of loads which is light and is badly needed by trapped persons, and has great popularization potential in the field of air-drop of emergency rescue supplies.

Goods logistics control method and goods logistics control system

The embodiments of the invention provide a goods logistics control method and a goods logistics control system. The method comprises the following steps: determining the receiving area, the shipping area and the transit station between the receiving area and the shipping area of goods according to the order information of the goods; generating a logistics waybill at least based on the receiving area and the shipping area determined; broadcasting the logistics waybill to deliverymen in the shipping area for waybill grabbing; sending a pickup order to the deliveryman grabbing the waybill in the shipping area; and in response to the delivery confirmation feedback of the deliveryman, broadcasting the logistics waybill to deliverymen in the receiving area for waybill grabbing, and sending a delivery order to the deliveryman grabbing the waybill in the receiving area. Through the method and the system provided by the invention, flexible and efficient operation in each region of goods delivery is realized. The functional division of deliverymen is made clear by means of waybill grabbing. The shipping area and the receiving area of cross-area goods are quickly connected through the transit station. The speed of goods delivery is improved greatly. Ordered and efficient circulation of goods is realized.
