Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, a concrete sandstone conveyor belt disclosed by the invention comprises a support frame 1 and a conveying roller 2, belt 3 and driving motor 4 that the slope set up, transfer roller 2 rotates with support frame 1 to be connected, driving motor 4's pivot and the welding of transfer roller 2, driving motor 4's casing welding is on support frame 1, belt 3 is around establishing in 2 week sides of two transfer rollers, the below of 3 lower ends of belt is equipped with collecting box 5, collecting box 5's opening is towards 3 lower surfaces of belt, it has two spinal branch vaulting poles 6 to follow vertical direction welding on collecting box 5, two spinal branch vaulting poles 6 have scraper blade 7 towards the one end welding of belt 3, one side and the 3 lower surface butt of belt that bracing piece 6 was kept away from to scraper blade 7, wear to be equipped with between belt 3 and strike pole 8, strike pole 8 and set up between scraper blade 7 and the transfer roller 2 of higher end, be provided with the first drive assembly that the drive struck the. When conveying the concrete grit, earlier by the 2 rotations of the drive motor 4 drive transfer roller of welding on

support frame

1, 2 transmission drive belt 3 of transfer roller rotate, place the concrete grit back on belt 3, belt 3 is carried the concrete grit to agitating unit, the pole 8 of beating that is equipped with beats belt 3 through first drive assembly, sand and earth after beating drop in collecting box 5, be equipped with scraper blade 7 on rethread collecting box 5 and to 3 surface cleaning of belt, scrape the sand and the earth of the pine of beating of adhesion on belt 3, increase the frictional force between belt 3 and the transfer roller 2, the conveying of belt 3 to the concrete grit has been made things convenient for, the work efficiency of belt 3 is improved.

In this embodiment, be provided with support 9 on the 5 lateral walls of collecting box, first drive assembly includes first motor 10, cam 11, connecting rod 12, supporting seat 13 sets up to two, two supporting seat 13 welds on collecting box 5, spout 22 has been seted up along vertical direction to supporting seat 13, cam 11 rotates with the supporting seat 13 that is equipped with spout 22 to be connected, the pivot of first motor 10 is coaxial and the welding of cam 11, the casing of first motor 10 just welds with support 9 in collecting box 5 side, connecting rod 12 just sets up along vertical direction with supporting seat 13 sliding connection, strike pole 8 and connecting rod 12 and be connected. When beating belt 3, the pivot by first motor 10 drives cam 11 and rotates, and cam 11 rotates and drives connecting rod 12 and slide on spout 22, and then beats belt 3 by connecting rod 12 drive rapping bar, has made things convenient for sand and the earth clearance of adhesion on belt 3 to fall.

Because beat belt 3 through beating pole 8, then through the scraper blade 7 that is equipped with after the sand and the earth clearance of adhesion on belt 3, still there are the sand and the earth that the adhesion is stronger on belt 3, consequently, collecting box 5 rotates and is connected with the brush roller 21 parallel with scraper blade 7, and brush roller 21 and belt 3 lower surface looks butt, and brush roller 21 is located between gas blow pipe 20 and scraper blade 7. The brush roller 21 is arranged to clean the belt 3 again, so that the friction force between the belt 3 and the conveying roller 2 is larger, and the working efficiency is higher.

Since the belt 3 contains much dust after the brush roller 21 cleans sand and mud adhered to the belt 3, the sidewall of the collection box 5 near the lower end of the belt 3 is vertically provided with the air blowing pipe 20, and the outlet of the air blowing pipe 20 faces the lower surface of the belt 3. Sand and earth that further adhere on 3 belts are cleared up, have reduced 3 belts's gravity, and 3 belts's rate of tension strengthens for the frictional force increase between 3 belts and the transfer roller 2 has further improved work efficiency.

Referring to fig. 3 and 4, since the sand and soil adhered to the belt 3 are sometimes blocky and are not easily broken, 9 protrusions 14 are arranged on one side of the striking rod 8 facing the lower portion of the belt 3 and along the axial direction of the belt at intervals, so that the sand and soil adhered to the belt 3 can be conveniently cleaned.
