For the detailed structure and function of the squeegee assembly 10, reference is made to the related contents in the foregoing description, and the details are not repeated here.
The scraper conveyor 100 is a device for transporting materials, which is commonly used in the mineral or grain production industry. Generally, the rack body 20 is provided with a transportation panel 30 and a driving mechanism on the rack body 20. The driving mechanism comprises a driving motor, two driving wheels 40 and two driven wheels 50. The driving motor, the two driving wheels 40 and the two driven wheels 50 are mounted on the stand body 20. The two driving wheels 40 are respectively connected to both sides of the supporter main body 20 and connected through a first rotation link, and the two driven wheels 50 are respectively connected to both sides of the supporter main body 20 and connected through a second rotation link. The driving rotating shaft of the driving motor is connected with the first rotating connecting rod. A transport chain 2 is connected between the driving pulley 40 and the driven pulley 50 on the same side of the holder body 20. A feeding device is arranged above the bracket main body 20, and a feeding port of the feeding device faces the transportation panel 30.
When the scraper conveyor 100 works, the driving motor drives the driving wheel 40 to rotate, and the driving wheel 40 drives the conveying chain 2 to rotate, so as to drive the scraper 1 to move from the driving wheel 40 to the driven wheel 50. The material falls on the transportation panel 30 from the feeding port, and is pushed by the scraper 1 after falling on the transportation panel 30. The scraper conveyor 100 provided with the scraper component 10 has a better material conveying effect, no material is left on the scraper 1, and the waste of materials in the conveying process is reduced. Moreover, three scraper surfaces of the scraper 1 can be replaced, the service life of the scraper 1 is longer, and the quality of the scraper conveyor 100 is improved.
To sum up, the utility model discloses a scraper blade subassembly 10 and scraper conveyor 100. The screed assembly 10 includes at least two screeds 1 and two conveyor chains 2 for moving the screeds 1. Two transportation chains 2 interval settings, scraper blade 1 is connected between two transportation chains 2. The scraping plate 1 is in a triangular prism shape, and the longitudinal section of the scraping plate 1 is in a triangular shape. The scraping plate 1 in the shape of the rhombus column can not accumulate materials when pushing the materials and remain on the scraping plate 1, so that the waste of the materials can not be caused, and the efficiency of conveying the materials is improved. On the other hand, since the scraper 1 has a rhombohedral shape, the contact surface of the scraper 1 with the material can be changed by rotating the scraper 1, so that the service life of the scraper 1 can be prolonged. The scraper conveyor 100 equipped with the scraper component 10 has better material conveying effect and higher quality, and is preferred.
The foregoing is considered as illustrative only of the principles and preferred embodiments of the invention. It should be noted that, for those skilled in the art, on the basis of the principle of the present invention, several other modifications can be made, and the protection scope of the present invention should be considered.
