[0034] Example 2:

[0035] Based on Example 1 Figure 5-7As shown, guide plates 3 and extrusion plates 4 are horizontally arranged on the inner side and above the conveyor belt 207; the guide plates 3 and the extrusion plates 4 are both arranged on the side of the directional cylinder 5 close to the input end of the conveyor belt 207; the guide plate 3 is bolted to the upper surface of the support plate 201, and the two ends of the edge of the guide plate 3 close to the directional cylinder 5 are bent upward and have an arc-shaped structure; the extrusion plate 4 is installed on a mounting assembly 7; the two ends of the edge of the extrusion plate 4 close to the directional cylinder 5 and the two ends of the edge away from the directional cylinder 5 are both bent upward and have an arc-shaped structure, and the diameter of the arc structure formed by the edge of the extrusion plate 4 close to the directional cylinder 5 is smaller than the diameter of the arc structure formed by the edge away from the directional cylinder 5; the diameter of the arc structure formed by the edge of the guide plate 3 close to the directional cylinder 5 is between the diameter of the arc structure formed by the edge of the extrusion plate 4 close to the directional cylinder 5 The diameter is between the diameter of the arc-shaped structure formed by an edge of the extrusion plate 4 away from the directional cylinder 5; a feeding gap is formed between the extrusion plate 4 and the conveyor belt 207; the mounting assembly 7 includes a pair of first mounting plates 701 respectively vertically arranged on opposite sides of the support plate 201; the opposite sides of the two first mounting plates 701 are vertically provided with a pair of through grooves 702 side by side; positioning columns 703 are inserted in the two pairs of through grooves 702; the two pairs of positioning columns 703 are bolted to the opposite sides of the first mounting plates 701 respectively; the upper edges of the two first mounting plates 701 are connected by a second mounting plate 704, and the two first mounting plates 701 are connected to the second mounting plate 704 by bolts; the upper surface of the second mounting plate 704 is vertically bolted with a pair of adjusting rods 705 side by side; the lower ends of the two adjusting rods 705 are bolted to the upper surface of the extrusion plate 4.

[0036] Example 3:

[0037] Based on Example 2, Figure 8-11As shown, the directional cylinder 5 includes a first semicircular plate 501 arranged horizontally and a second semicircular plate 502 arranged horizontally above the first semicircular plate 501; the first semicircular plate 501 and the second semicircular plate 502 can be combined to form a cylindrical structure, and the conveyor belt 207 is interspersed in the cylindrical structure; the first semicircular plate 501 is bolted to the upper surface of the support plate 201 through a plurality of brackets 503 arranged side by side; the opposite two sides of the first semicircular plate 501 and the opposite two sides of the second semicircular plate 502 are horizontally welded with side stays 504, and the two side stays 504 in the upper and lower positions are connected by bolts; the circumferential side surfaces of the first semicircular plate 501 and the circumferential side surfaces of the second semicircular plate 502 are evenly distributed with a plurality of heat dissipation holes 505; the two ports of the first semicircular plate 501 and the two ports of the second semicircular plate 502 are integrated The shape has an outer flange 506, and when the two first semicircular plates 501 are merged with the second semicircular plate 502, a trumpet-shaped structure is formed between the two outer flanges 506 in the upper and lower positions; the forming rod 6 is coaxially arranged in the cylindrical structure formed by the merger of the first semicircular plate 501 and the second semicircular plate 502, and the forming rod 6 and the directional cylinder 5 are connected by a bearing assembly 8; the bearing assembly 8 includes a bearing strip 801 connected to the top of the second semicircular plate 502 by horizontal bolts; a pair of bearing rods 802 are connected to the bearing strip 801 by vertical bolts side by side; the lower ends of the two bearing rods 802 are bolted to the circumferential side of the second semicircular plate 502; the lower surface of one end of the bearing strip 801 is vertically bolted to multiple connecting columns 803; the lower ends of multiple connecting columns 803 are bolted to one end of the forming rod 6 near the input end of the conveyor belt 207.

During use, the upper end of the mounting post 901 is slidably inserted into the circumferential side wall of the lifting sleeve 905, and the block 907 is clamped in the limiting groove 904, thereby achieving the positioning of the brush head 906; and when it is necessary to clean the surface of the conveyor belt 207, the handheld operating rod 903 is moved upward to cause the mounting post 901 to disengage from the lifting sleeve 905, and then the block 907 is taken out from the limiting groove 904. Then the worker holds the operating rod 903 and uses the brush head 906 to manually clean the surface of the conveyor belt 207, so that the debris on the conveyor belt 207 is swept off the edge of the conveyor belt 207.
