The present application relates to the technical field of coal conveying, in particular to a hanging belt conveyor for coal mine conveying, comprising a belt, the two sides of the belt being fixedly connected with supports, the present application is provided with a screening assembly inside the shell, during the sampling process, the motor starts to control the gradually opening of the opening and closing plate, so that the size of the coal entering the collection chamber inside is increased, at this time, the screening assembly screens, so that the collection bucket collects coal of each size with gradually increasing size each time, and too much coal of the same size is not collected, therefore, the design of the collection bucket will gradually open with the opening and closing plate and be screened by the screening assembly, so that the collection bucket can collect all the coal particles of various particle sizes on the belt, so that the detection assembly can detect coal of various sizes, and the detection accuracy is ensured.

A towing device for construction projects, relating to the field of construction engineering technology, includes a pallet, a towing handle rotatably mounted on the pallet, and several casters fixed to the bottom of the pallet. The pallet includes two side walls along its length, with two limiting mechanisms on the side walls. A guardrail along the length of the pallet is rotatably mounted on each of the two limiting mechanisms, and the two guardrails are arranged opposite each other along the width of the pallet. The top surface of the pallet has two recessed receiving grooves adapted to the two guardrails, and the bottom of the receiving grooves has several first row of miscellaneous holes penetrating the pallet. A transverse baffle is fixedly installed on the side of the pallet away from the towing handle, and the transverse baffle is arranged along the width of the pallet. This utility model can transport construction materials of different shapes, improving its applicability, reducing construction costs, and improving work efficiency.
