Detailed Description

The technical solution of the present invention will be further explained with reference to the drawings in the embodiments of the present invention.

As shown in figure 1, the sand feeding device comprises a hopper 1, a frame 2 and a belt conveyer,

hopper 1 sets up in frame 2, band conveyer sets up in frame 2 to be located hopper 1 under the position, rotatable being provided with eccentric bearing roller 4 on frame 2, eccentric bearing roller 4 is located hopper 1's below position and is holding in the palm band conveyer's conveyor belt 56.

The eccentric idler 4 is located at a position on the side of the hopper 1 from which sand is to leave in the direction of advance of the conveyor belt 56.

The eccentric carrier rollers 4 may be provided in several numbers, one of which is located at a position on the side of the hopper 1 from which the sand is going to leave in the advancing direction of the conveyor belt 56, and the other of which is located at a position directly below the hopper 1.

The belt conveyor also comprises a carrier roller 3, a first rubber roller 51, a second rubber roller 52 and a first driving motor 6,

the left and right sides of the first rubber roller 51 and the second rubber roller 52 are respectively rotatably arranged on the frame 2, the carrier rollers 3 are provided with a plurality of rollers which are rotatably arranged on the frame 2, the conveying belt 56 is annularly wrapped on the first rubber roller 51 and the second rubber roller 52 and is tightly attached to the upper surface of the carrier roller 3,

the second rubber roller 52 is coaxially connected with a driven chain wheel 53, the first driving motor 6 is installed on the frame 2, an output shaft of the first driving motor is coaxially connected with a driving chain wheel 54, and the driven chain wheel 53 is in transmission connection with the driving chain wheel 54 through a first chain 55.

As shown in fig. 2, a schematic view of the eccentric idler 4 is shown.

The working principle of the eccentric carrier roller is as follows: as shown in fig. 1, the sand is often deposited at a position on the side of the hopper 1 where the sand is about to leave the hopper 1 in the advancing direction of the conveyor belt 56, that is, at the lowermost left position of the hopper 1 in fig. 1. Therefore, an eccentric idler 4 is provided here. The eccentric carrier roller 4 rotates with the belt during belt conveyance, and the gap between the lower side of the hopper 1 and the belt varies from time to time due to its eccentricity, and may be large or small. When larger sand is piled up and stuck, the sand can be loosened and conveyed out when the gap is larger. Meanwhile, the clearance is not always kept in a large state, and the sand and the stone are effectively prevented from scattering from the clearance. On the other hand, eccentric bearing roller 4 can produce ascending thrust action to the grit at the pivoted in-process, plays not hard up effect to the grit in the hopper 1, prevents its harden design, can't carry away.

As shown in fig. 3, the gravel loading device further comprises a bracket 81, a stirring shaft 82, a large chain wheel 83, a second chain 85, a small chain wheel 86 and a second driving motor 84,

support 81 sets up in frame 2, (mixing) shaft 82 runs through the lower extreme of hopper 1 to rotate with support 81 and be connected, be provided with the auger on the (mixing) shaft 82, second driving motor 84 sets up in frame 2, its output shaft coaxial coupling little sprocket 86, the big sprocket 83 of (mixing) shaft 82 coaxial coupling, little sprocket 86 and big sprocket 83 pass through second chain 85 transmission and connect.

As shown in fig. 4, the stirring shaft 82 has a plurality of rotating shafts which pass through the discharge opening at the lower end of the hopper 1 and are rotatably disposed on the support 81, and is coaxially connected with the driving sprocket 87, the driving sprocket 87 is in driving connection through a third chain 88, and the support 81 is provided with a tension sprocket 89.

The working principle of the stirring shaft is as follows: as shown in fig. 3, in the case that the sand still cannot be conveyed out through the eccentric idler 4, the second driving motor 84 can be started to drive the stirring shaft 82 to rotate, so that the sand is loosened and easy to convey.

As shown in fig. 4, the stirring shafts 82 may be provided in three, parallel arrangement.
