Description

Technical Field

[0001] This utility model relates to the field of river sand transportation technology, and in particular to a river sand transportation device. Background Technology

[0002] River sand, as an important raw material in construction, water conservancy and other engineering fields, directly affects the overall progress and ecological benefits of engineering projects in terms of the efficiency and environmental protection of its transportation process. At present, there are still many technical pain points in the practical application of river sand transportation equipment, which restricts the improvement of operation quality. First, in terms of conveyor belt cleaning, river sand, especially sticky river sand with high mud content, is easy to adhere to the surface of the conveyor belt during transportation, forming residues. These residues not only waste river sand resources, but also fall with the operation of the conveyor belt, causing dust to fill the work area and making the environment dirty and messy, while increasing the cost of manual cleaning later. Second, in the collection and discharge process, the cleaned river sand needs to be temporarily stored in the collection box. However, river sand is easy to accumulate in the box and form dead corners, resulting in poor discharge and frequent blockages. It is necessary to stop the machine for manual cleaning, which seriously affects the continuity of operation. Moreover, during manual dumping, the river sand comes into violent contact with the air, generating a large amount of dust, which not only violates environmental protection standards, but also harms the respiratory health of operators. Utility Model Content

[0003] The purpose of this invention is to provide a river sand conveying device to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a river sand conveying device, including a support, a baffle fixedly connected to the support, a horizontal bar fixedly connected to the support, and a fastening clamp shaft fixedly connected to the upper surface of the horizontal bar, a shaft body sleeved inside the fastening clamp shaft, a rotating cylinder sleeved on the outer side of the shaft body, and a fixing member fixedly connected to one end of the support.

[0005] As a further technical solution of this utility model, a roller is provided inside the fixing member, and a drum is provided on the outside of the roller.

[0006] As a further technical solution of this utility model, a dual-stage adaptive cleaning mechanism is provided on the outer bottom of the roller. The dual-stage adaptive cleaning mechanism includes a fixed base, a groove, a mounting seat, an elastic element, a shaft, a first rotating shaft, a rotating element, an arc-shaped scraper, a second rotating shaft, a roller brush, a shaft hole, and a micro motor.

[0007] As a further technical solution of this utility model, the upper surface of the fixed base is provided with a groove, a mounting seat is provided in the groove, an elastic element is provided in the mounting seat, a shaft is fixedly connected to the elastic element, a shaft hole is provided on the shaft, a second rotating shaft is sleeved in the shaft hole, a roller brush is provided on the outside of the second rotating shaft, and a micro motor is provided at one end of the second rotating shaft.

[0008] As a further technical solution of this utility model, the upper surface of the fixed base is provided with a mounting seat, an elastic element is provided inside the mounting seat, a shaft is fixedly connected to the elastic element, a shaft hole is opened on the shaft, a first rotating shaft is sleeved in the shaft hole, and an arc-shaped scraper is provided on the outer side of the first rotating shaft.

[0009] As a further technical solution of this utility model, the bottom of the dual-stage adaptive cleaning mechanism is provided with a suppression mechanism. The suppression mechanism includes a conical funnel, a first channel, a discharge cylinder, a spiral feeder, a main shaft, a motor compartment, a rotating motor, a collection compartment, a second channel, a dust removal pipe, an adapter, a negative pressure fan, and an ultrasonic level sensor. An ultrasonic level sensor is fixedly connected to the outer wall of the conical funnel. A first channel is opened on the bottom outer wall of the conical funnel. A discharge cylinder is sleeved in the first channel. A spiral feeder is provided in the discharge cylinder. A main shaft is sleeved in the center of the spiral feeder. A motor compartment is provided at the end of the main shaft. A rotating motor is provided in the motor compartment.

[0010] As a further technical solution of this utility model, a dust removal pipe is provided on one side of the outer wall of the conical funnel, an adapter is provided at one end of the dust removal pipe, a negative pressure fan is provided at one end of the adapter, a collection chamber is provided at the end of the dust removal pipe, a second through groove is provided on the upper surface of the collection chamber, and a discharge cylinder is sleeved in the second through groove.

[0011] Compared with existing technologies, the beneficial effects achieved by this utility model are as follows: This utility model adopts a structured design. Through an innovatively designed dual-stage adaptive cleaning mechanism and an automatic material discharge and dust suppression structure for the collection box, it achieves synergistic optimization of efficient cleaning, intelligent material discharge, and environmentally friendly operation in river sand conveying. In terms of cleaning, this new model employs a dual-stage progressive cleaning structure of scrapers and roller brushes, forming a stepped residual treatment logic. The scrapers, through rigid contact, first peel off large adhering sand particles and clumps from the conveyor belt surface. Especially for sticky river sand with high mud content, it can remove more than 70% of stubborn residue in one go. Subsequently, the roller brushes, through high-speed reverse rotation, perform deep cleaning of the fine residue after the scraper treatment. This dual-stage cleaning mode significantly reduces the loss of river sand during conveying, improves resource utilization by more than 80%, and avoids the waste caused by residual sand particles falling under traditional single cleaning methods. Furthermore, the roller brushes and scrapers are connected by elastic supports. The composite pressure regulation system, which combines mechanical fine-tuning with elastic element contact pressure, ensures dynamic and tight contact between the roller brush and the conveyor belt. The scraper is made of wear-resistant rubber with a Shore hardness of 60-70HA, which has a certain elastic deformation capacity and can adapt to the slight unevenness and tension fluctuations on the surface of the conveyor belt. The scraper angle can be flexibly adjusted within a certain range through the rotating shaft. Combined with the reverse rotation design of the roller brush, it can effectively avoid impurities such as small stones and grass roots mixed in the river sand and smoothly guide them into the collection structure. In addition, the device adopts a conical funnel structure, which, together with the spiral discharger and ultrasonic level gauge, forms a closed-loop control system. When the river sand accumulates to 80% of the box volume, the system automatically starts the discharge program and automatically stops when it drops to 20%. No manual intervention is required throughout the process. This design completely solves the downtime waiting problem of the traditional manual dumping mode, extends the continuous operation time of the device, reduces the frequency of manual operation, and significantly reduces labor costs and the risk of operation interruption.
