Detailed Description
The sand feeding device of the vertical sand tank comprises a rack 1, a bucket elevator 2, a feeding belt conveyor 3 and a bag breaking cone 4 (see the attached figure 1 of the specification).
A bucket elevator 2 is arranged on the frame 1; the bucket elevator 2 is outsourcing equipment; the outlet at the upper end of the bucket elevator 2 corresponds to the inlet of the vertical sand tank, and sand output by the bucket elevator 2 can be directly input into the vertical sand tank during operation.
The lower end inlet of the bucket elevator 2 is positioned at the lower end of the frame 1; a feeding belt conveyor 3 is arranged on one side of the bucket elevator 2 (see the attached figure 1 of the specification).
The feeding belt machine 3 comprises a mounting frame 7, a conveying belt 8, a supporting carrier roller 9, a driving roller 10, a driven roller 11, a dust cover 12, a reversing roller 13 and a fixed pull rod 14; the upper part and the lower part of the mounting rack 7 are fixedly connected with the machine frame 1 through a plurality of fixing pull rods 14 (refer to the attached figure 1 in the specification).
The fixed pull rod 14 consists of an adjusting sleeve 16, an adjusting screw 17 and a connecting ring 18; the two end heads of the adjusting sleeve 16 are respectively in threaded connection with an adjusting screw 17; the adjusting screw 17 is provided with a connecting ring 18 at the end (see the attached figure 4 in the specification). During assembly, the connecting ring 18 at one end of the fixed pull rod 14 is fixedly connected with the mounting frame 7 of the feeding belt machine 3 through a bolt; the connecting ring 18 at the other end of the fixed pull rod 14 is fixedly connected with the frame 1 through a bolt. After the assembly is finished, the adjusting sleeve 16 is rotated forward, and then the adjusting screws 17 can be driven to approach each other; the adjusting screw rods 17 can be driven to separate from each other by reversely rotating the adjusting sleeve 16; therefore, the length of the fixed pull rod 14 can be adjusted by rotating the adjusting sleeve 16, and the purpose of fixedly mounting the feeding belt machine 3 on the frame 1 is achieved.
The upper end of the mounting rack 7 is provided with a driving roller 10 through a driving motor; the lower end of the mounting rack 7 is provided with a driven roller 11; the driving roller 10 and the driven roller 11 are sleeved with a conveying belt 8; a support roller 9 is arranged on the mounting rack 7 at the inner side of the conveying belt 8; the supporting idler rollers 9 are in supporting connection with the inner side of the conveying belt 8 (see the description and the attached figure 2); when the driving motor drives the driving roller 10 to rotate, the driving roller 10 can drive the conveying belt 8 to rotate anticlockwise under the matching of the driven roller 11 and the supporting carrier roller 9.
The outside of the conveying belt 8 is symmetrically provided with leakage-proof flanges 15 (see the attached figure 5 in the specification). The leakage-proof flanges 15 are arranged for the purpose of: so that the leakage-proof ribs 15 can limit the sand grains on two sides during the process of conveying the sand grains by the conveying belt 8, and the problem that the sand grains slide off from two sides of the conveying belt 8 is avoided.
The leakage-proof ribs 15 are in a wave-shaped structure (see the attached figure 5 in the specification). The leakage-proof rib 15 is arranged into a wave-shaped structure for the purpose of: the whole conveying belt 8 is in a circular ring-shaped structure; when the conveying belt 8 runs to the turning part, the top end of the anti-leakage rib 15 with the wave-shaped structure can provide a certain buffer space for the deformation of the conveying belt, so that the problem that the anti-leakage rib 15 is stressed to deform at the turning part is avoided.
The lower end of the conveying belt 8 is in a horizontal shape, and the upper end of the conveying belt is in an inclined structure (see the attached figure 2 in the specification); the purpose of arranging the conveyor belt 8 in this way is: to avoid the problem that a part of sand grains leak from the lower end when the whole conveying belt 8 is in an inclined state.
The mounting frames 7 on two sides of the joint of the horizontal section and the inclined section of the conveying belt 8 are provided with reversing rollers 13 (see the attached figures 2 and 6 in the specification); the reversing roller 13 is in rolling connection with the conveyor belt 8. The reversing roller 13 is provided for the purpose of: so that during operation, conveyor belt 8 can laminate the support bearing roller 9 on the mounting bracket 7 all the time under the limiting action of switching-over roller 13, to avoid when initiative cylinder 10 rotates pulling conveyor belt 8, conveyor belt 8 breaks away from the problem emergence of support bearing roller 9.
A dust cover 12 is arranged on the frame 1 outside the conveying belt 8 (see the attached figure 2 in the specification); the dust cover 12 is provided for the purpose of: so that during operation, dust cover 12 can be all sealed with material loading belt feeder 3 to avoided the dust to leak and lead to the poor problem of construction environment.
A discharge hole is formed in the dust cover 12 below the end head at the upper end of the conveying belt 8; a connecting chute 5 (see the attached figure 2 in the specification) is hinged at the discharge port; when the feeding belt conveyor 3 is in a transportation state, the connecting chute 5 can be rotated to the top end of the mounting frame 7 to be fixed (see the attached figure 2 in the specification), so that the connecting chute 5 and the mounting frame 7 are kept on the same straight line, and the purpose of facilitating the transportation of the feeding belt conveyor 3 is further achieved.
When the feeding belt conveyor 3 is assembled, the connecting chute 5 can be rotated to the discharge port of the feeding belt conveyor 3 and fixed, and then communicated with the inlet of the hopper lifting machine 2. When the device works in this way, sand output by the feeding belt conveyor 3 can be directly input into the bucket elevator 2 through the connecting chute 5.
A feed hopper 6 is connected to a dust cover 12 above the horizontal section at the lower end of the conveying belt 8, and a bag breaking cone 4 is fixedly arranged inside the feed hopper 6 (see the attached figure 2 in the specification).
When the sand feeding device of the vertical sand tank works, the bucket elevator 2 and the feeding belt conveyor 3 are started firstly; then use the forklift to adopt the mode of hoist and mount, transport the ton bag that is equipped with the sand grain to the top of feeder hopper 6, then fall the ton bag downwards, make it and broken bag awl 4 contact to the ton bag is lacerated through broken bag awl 4. After the ton bag is scratched, sand grains inside the ton bag enter the feeding belt conveyor 3 under the action of self weight, then the running feeding belt conveyor 3 can convey the sand grains to the bucket elevator 2 through the connecting chute 5, and then the bucket elevator 2 can convey the sand grains to the vertical sand tank, so that the sand feeding work of the vertical sand tank can be completed.
