Intelligent sand dredging control system and method for sand dredger

Abstract

The invention discloses an intelligent dredging control system and method of a dredging boat. The system comprises a programmable control unit, a plurality of buckets, a bucket control system, a boat sailing control system and a water depth measuring apparatus, wherein the bucket control system comprises a frequency converter, a bucket motor, the buckets and a current transducer which is used for detecting the load current of the buckets; the outputs of the water depth measuring apparatus and the current transducer are respectively connected with the programmable control unit; the output of the programmable control unit is connected with the buckets sequentially through the frequency converter and the bucket motor; the output of the programmable control unit is also connected with a transmission chain by a transmission chain drive motor. The intelligent dredging control system and the method of the dredging boat have the beneficial effects that the sand amount in the buckets is calculated through detecting the load current of each bucket by the current transducer, the water entering depth of the bottom of a main support is automatically adjusted according to the sand amount, the idling of the buckets is avoided, the transmission speed of the transmission chain is adjusted according to the sand amount in the buckets, the pressure of the buckets on the main support is reduced, and when sand enters a screening device, the sand and stone can be separated by using high speed.

Description

technical field [0001] The invention relates to an intelligent dredging control system and method for a dredging ship. Background technique [0002] Sand dredgers, also known as dredgers, dredging machines, and sand kings, as the name suggests, are sand and gravel mining tools, mostly for mobile operations, and the floating body adopts an assembled box structure. Equipped with digging device, screening device, lifting device, conveying device, etc. The bucket is driven by the power device to load the material, the stones are passed out by the conveyor belt through the screening, and the sand is transferred to the designated place by the conveyor belt. [0003] Because the river bed is divided into sand layer, stone layer and rock layer. Our purpose is to dig sand, so the depth of the bucket extending into the river bed plays a key role, that is: digging too shallow will cause the digging to be unclean, the bucket often runs empty, and resources are wasted; A small amount ...

Problems solved by technology

Our purpose is to dig sand, so the depth of the bucket extending into the river bed plays a key role, that is: digging too shallow leads to unclean digging, the bucket often runs empty, and wastes resources; A small amount will also cause the bucket to run empty, and the bucket will rub against the stone layer, causing large mechanical wear and reducing the service life of the bucket

Existing sand dredgers need people to observe the amount of sand in the bucket to adjust the depth of the bucket. After the sand dredging in one area is completed, it needs to be manually adjusted to enter the next sand dredging area. The operation is complicated, and the depth of sand dredging is difficult to grasp
