Description of reference numerals: the chute comprises a chute body 1, a feeding hole 2, material blocking plates 3, a middle material blocking plate 3-1, material blocking plates 3-2 on two sides, material flow 4, a belt conveyor 5 and a discharging hole 6.
Detailed Description
The utility model will be described in detail below with reference to the following drawings:
example (b): as shown in the attached drawings, the buffering blanking chute comprises a chute body 1, a feeding hole 2, a material baffle plate 3 and a discharging hole 6, wherein the chute body 1 is arranged above the feeding end of a belt conveyor 5, the feeding hole 2 is formed in the middle position of the top of the chute body 1 for material flow 4 to enter, the discharging hole 6 is formed in the middle position of the bottom of the chute body 1 for material flow 4 to discharge, and the discharging hole 6 is arranged right opposite to the center of a belt of the belt conveyor 5; the chute comprises a chute body 1, a plurality of stages of striker plates 3 are sequentially arranged in the height direction of the inner wall of the chute body 1 from top to bottom, and the striker plates 3 and the inner wall of the chute body 1 are fixed through welding. The striker plates 3 include middle striker plates 3-1 and two side striker plates 3-2 which are arranged in a staggered manner, as shown in fig. 1, four stages of striker plates 3 are taken as an example in this embodiment, and may be more stages. The middle material baffle 3-1 is arranged along the middle position of the inner wall of the chute body 1, the middle material baffle 3-1 adopts a structure with closed two-side open in the middle, the material flow 4 can only pass through the two sides of the middle material baffle 3-1 to realize buffering and diversion, the material baffles 3-2 on the two sides are arranged along the two-side positions of the inner wall of the chute body 1, the material baffles 3-2 on the two sides adopt a structure with one side closed and the other side open, and the material flow 4 can only realize buffering and convergence through the middle of the material baffles 3-2 on the two sides; in the embodiment, the first-stage striker plate 3 arranged close to the feed inlet 2 is a middle striker plate 3-1, and the third-stage striker plate 3 is also the middle striker plate 3-1; the last-stage material baffle 3 arranged close to the discharge port 6 is a material baffle 3-2 on two sides, and the second-stage material baffle 3 is also a material baffle 3-2 on two sides.
Preferably, the striker plates 3 are made of steel plates with the thickness of 20mm, the height difference between all levels of the striker plates 3 is 600mm, and one or two groups of the striker plates 3 can be properly reduced under the condition that the fall of the chute is small.
