Detailed Description

Example one

Referring to the figures, the blade type material flattening device comprises a screw sleeve base 1, a front supporting rod 3, a front shaft sleeve 5, a front blade 6, a side plate 7, a middle blade 8, a rear shaft sleeve 9, a rear blade 10 and a rear supporting rod 11; the number of the side plates 7 is two, the front blade 6, the middle blade 8 and the rear blade 10 are welded between the two side plates 7 in an inclined mode, wherein the length of the front blade 6 is smaller than that of the middle blade 8, and the length of the middle blade 8 is smaller than that of the rear blade 10; two ends of the side plate 7 are respectively welded with a pin shaft 4, wherein the pin shaft 4 at the front end is arranged on the two front shaft sleeves 5, the pin shaft 4 at the rear end is arranged on the two rear shaft sleeves 9, the two front shaft sleeves 5 are respectively welded at the top ends of the two front supporting rods 3, and the two rear shaft sleeves 9 are respectively welded at the top ends of the two rear supporting rods 11; the lower parts of the front supporting rod 3 and the rear supporting rod 11 are respectively provided with an external thread 2, the front supporting rod 3 and the rear supporting rod 11 are installed on the screw sleeve base 1 through threads, and a foundation bolt installation hole is formed in a bottom plate of the screw sleeve base 1; the included angles between the front blade 6, the middle blade 8 and the rear blade 10 and the horizontal direction are 60 degrees; the number of the foundation bolt mounting holes in the bottom plate of the screw sleeve base 1 is 4, and the screw sleeve base 1 is mounted on the ground through foundation bolts.

Taking the material leveling of a belt conveyor for conveying materials upwards as an example, two of four screw sleeve bases are placed on two sides of the belt conveyor as a group, and then the material leveling mechanism is assembled and debugged. The material leveling mechanism is assembled with the screw sleeve base from the position, above the belt, of the belt, wherein the belt (the blades are perpendicular to the conveying belt) in a crossing mode, and the belt for conveying materials upwards is inclined, so that the height of the front supporting rod needs to be adjusted first, and then the height of the rear supporting rod needs to be adjusted. The height of the front shaft sleeve is adjusted by screwing the screw sleeve bases at the bottoms of the two front supporting rods, so that the distance between the bottom ends of the front blades and the belt is smaller than the height of the belt material (namely, the front blades can scrape the material when the belt transmits the material, the first material leveling is realized, and the material leveling height is not smaller than 2 cm). The height of the rear shaft sleeve is adjusted by screwing the screw sleeve bases of the two rear supporting rod bottom plates, so that the two side plates are parallel to the transmission belt. And after the height and the inclined bottom crossing of the leveling mechanism are adjusted, namely the position of the whole leveling device is determined, the four screw sleeve bases are fixed on the cement ground of the workshop by using foundation bolts. When the belt conveyor conveys materials upwards for the crusher, the materials stacked on the belt are firstly flattened by the front blades for the first time, then are flattened for the second time by the middle blades with the lengths larger than the front blades, and finally are flattened for the third time by the rear blades with the lengths larger than the middle blades, and the materials uniformly enter the crusher after being flattened. The material flattening device is installed at the feeding front end of the belt conveyor and is used for flattening materials on the conveying belt through the blades, so that the materials can uniformly enter the roller type crusher to be crushed. And then reduce the scouring and wearing and tearing to breaker roller middle part, improved the life of roller, reduced the maintenance frequency, reduced cost of maintenance, improved production efficiency.
