Further, the axes of the two second webs 120 are collinear, and the axis of the second web 120 is not collinear with the axis of the first web 110. In other words, the projections of the two second webs 120 onto the first web 110 are coincident, but the projections of the second webs 120 onto the first web 110 are not completely, i.e. only partially, or not coincident with the first web 110. Connecting the geometric center of one second web 120, the geometric center of the first web 110 and the geometric center of the other second web 120 in that order is a polyline.

Further, the distance between the second spoke plate 120 and the first spoke plate 110 on the first side and the distance between the second spoke plate 120 and the first spoke plate 110 on the second side can be the same or different, and flexible arrangement is performed according to actual requirements.

Further, the number of the spokes 130 is plural, both ends of each spoke 130 are respectively connected with the second web 120 at the first side and the second web 120 at the second side, and the spokes 130 are connected with the first web 110. Specifically, when the distance between the two second webs 120 and the first web 110 is the same, each spoke 130 is bent at a certain angle at the middle position, the bent part of the spoke 130 is connected to the first web 110, and the two ends of the spoke 130 are respectively connected to the two second webs 120. The portion of the spoke 130 on the first side is referred to as a first portion 131, the portion of the spoke 130 on the second side is referred to as a second portion 132, and the first portion 131 and the second portion 132 are symmetrical at the bending position of the spoke 130. In other words, the spokes 130 are generally in the shape of a broken line, i.e., a V-shape. Of course, when the worker processes the spoke 130, the spoke 130 can be smoothly transited at the bending position, so that the edge is prevented from being too convex to scratch the conveying belt 230. In addition, the spoke 130 can also be directly machined into two segments, and the two segments are combined into one spoke 130.

It is worth mentioning that the spokes 130 are connected with the circumferential side wall of the spoke plate to form a hollow-structured cylinder, so that the weight is low and the material is saved.

Further, all of the spokes 130 are parallel to each other at the first side portion, and the spoke 130 is parallel to each other at the second side portion. It can be understood that the direction-changing drum 100 in the present embodiment is symmetrical about the first radial plate 110 and is V-shaped, but the bending angle is not obvious. The working surface of the conveyer belt 230 transports the materials, the non-working surface is in friction fit with the direction-changing drum 100 and other rotating shafts 220, the conveyer belt 230 drives the direction-changing drum 100 to rotate, and the direction-changing drum 100 can change the direction of the conveyer belt 230. When some broken stones are scattered on the non-working surface of the conveying belt 230 and the plow type sweeper is not cleaned, the broken stones come to the contact position of the direction-changing drum 100 and the conveying belt 230 and enter the hollow direction-changing drum 100, are guided by the V-shaped spokes 130 and are finally discharged from two sides of the direction-changing drum 100, the possibility that the broken stones are gathered on the non-working surface of the conveying belt 230 and do not scratch or damage the conveying belt 230 is greatly reduced, the broken stones are favorably discharged in time, and the service life of the conveying belt 230 is prolonged.

Further, since the bend pulley 100 is generally V-shaped, when the bend pulley 100 is in friction fit with the conveyor belt 230, the section of the conveyor belt 230 is also approximately V-shaped, and the bend pulley 100 mainly depends on two sides of the spoke 130 to be in friction fit with the conveyor belt 230, so that the section of the conveyor belt 230 matched with the bend pulley 100 tends to move toward the middle of the bend pulley 100, that is, the V-shaped bend pulley 100 can correct the deviation of the conveyor belt 230, and the risk of deviation of the conveyor belt 230 can be greatly reduced.

Further, at least a portion of the spoke 130 is located within the first connecting slot 111, it being understood that there may be a portion of the spoke 130 that is located outside of the first connecting slot 111. The worker processes the size and depth of the first coupling groove 111 according to the size of the spoke 130. By exposing part of the spokes 130 to the outside of the first connecting groove 111, the possibility that the spokes scratch the conveyor belt 230 when the turnabout drum 100 rotates can be reduced, and the service life of the conveyor belt 230 is further prolonged.

It should be noted that the first connecting slot 111 may have other shapes, and the spoke 130 may also be made of rectangular steel plate, and the first connecting slot 111 and the spoke 130 may be flexibly arranged in consideration of the connecting strength, the processing difficulty, and other factors.

Further, the spokes 130 may have a size of 1/4 to 1/3 outside the first connecting groove 111. The connecting strength of the first web plate 110 and the spokes 130 can be ensured, and the first web plate 110 can be prevented from scratching the conveying belt 230.

Further, the longitudinal direction of the first connecting groove 111 is parallel to the axial direction of the first web 110. It can be understood that, after the spoke 130 is placed in the first connecting groove 111, the first portion 131 and the second portion 132 of the spoke 130 are perpendicular to the side wall of the first web 110, which is beneficial to reducing the processing difficulty of the first connecting groove 111 and improving the connecting strength between the first web 110 and the spoke 130.

Further, the length direction of the second connecting groove 121 is not parallel to the axial direction of the second web plate 120, that is, after the end portion or the position close to the end portion of the spoke 130 is placed into the second connecting groove 121, a part of the spoke 130 located on the same side is not perpendicular to the second web plate 120, which is beneficial to forming a V-shaped structure by the spoke 130 and the direction-changing drum 100, and the spoke 130 is fixed according to the designed shape, so that the connecting strength is improved.
