A dry-wet cycle testing device capable of monitoring moisture content of soil in real time comprises a drying tank, a saturation tank, a power supply tank, a rotating device and a reading control device, wherein the drying tank promotes drying of soil samples by means of fans and a blower; the saturation tank performs humidification saturation on the soil samples by means of a humidifier; the power supply tank is located at the bottom of the device; the rotating device is divided into a self-rotating device and an around-circular-ring-track rotating device; the reading control device monitors the moisture content of the soil samples in real time. The dry-wet cycle testing device has the advantages that dry-wet cycle can be performed on the multiple soil samples with different water content ranges simultaneously, saturation and drying are more uniform by means of the special rotating device in the dry-wet cycle process, the moisture content of the soil samples can be monitored at any time, indication lamps can be lightened when preset moisture content is reached, and the dry-wet cycle on the soil samples is performed precisely.

The invention relates to the technical field of water for garden landscapes, and discloses a circulating water system for garden landscapes. A water tank, a partition plate is fixed at the center of the lower surface of the water storage tank, a discharge pipe is symmetrically fixed at the bottom of the water storage tank, a first solenoid valve is fixed at the bottom ends of the two discharge pipes, and two The top of the discharge pipe is fixed with a fourth solenoid valve; the present invention can collect rainwater, and can supply the collected rainwater to the water device and the sprinkler irrigation device, and when the water device is not in use, the water in it can be in the water. Under the action of the second pump body, it enters the high-level water tank again through the second return pipe, and can continue to supply the water device and the sprinkler irrigation device for use next time, and the moisture sensor at the bottom of the sprinkler irrigation device can monitor the moisture content in the soil in real time.

The invention relates to a pre-storage hopper processing and monitoring system and operation method of a ready-mixed concrete mixer. A pre-storage hopper is arranged under the hopper, and an automatic control opening and closing material inlet and an automatic control opening and closing discharge port are arranged on the upper and lower sides of the pre-storage hopper; the inner wall of the pre-storage hopper Set a negative pressure air duct, and set a dust removal device on its upper part; set a stress sensing plate at the lower part of the pre-storage hopper, and monitor the feeding amount and stocking amount in the pre-storage hopper through the stress sensing plate; set a humidity sensor at the lower part of the inner wall of the pre-storage hopper, The moisture content of concrete is monitored in real time, and a water inlet is set on the top of the pre-storage hopper. The present invention relates to a pre-storage hopper processing and monitoring system and operation method of a ready-mixed concrete mixer, which performs corresponding buffering of concrete to avoid the risk of material spilling out, and at the same time monitors the moisture content state of the concrete in the pre-storage hopper as well as the amount of stored material and the amount of material used in real time. Monitoring, reducing the waiting time of vehicles, improving transportation efficiency, has good economic and technical benefits.
