Description

Technical Field

[0001] The utility model relates to the field of pouring and conveying equipment, in particular to a telescopic rotating hopper. Background Art

[0002] In some large-scale channel construction, the workload is substantial due to the large-scale linear excavation, warehouse preparation, and pouring operations, requiring high efficiency. Transporting concrete requires multiple conveyor sets to relay the materials. Due to the height difference between the conveyors above and within the channel, a transfer hopper is required between the two conveyor sets to guide the concrete onto the conveyor within the channel. However, when pouring concrete within large channels, the height of the conveyor within the channel must be adjusted as the pouring height changes, resulting in a change in the height between the conveyors above and within the channel. However, conventional transfer hoppers are fixed in length or height and cannot accommodate this height difference. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a telescopic rotating hopper, which can adjust its length as the height between two groups of conveyors changes, so as to meet the needs of guiding materials between the two groups of conveyors with a height difference.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a telescopic rotating hopper, including a top hopper and a tail hopper, a plurality of intermediate hoppers are provided between the top hopper and the tail hopper, and the plurality of intermediate hoppers are fitted into each other, the top hopper is fitted into the uppermost intermediate hopper, and the lowermost intermediate hopper is fitted into the tail hopper, the top hopper is connected to the truss of the upstream first conveyor through a support frame, and the tail hopper is connected to the truss of the downstream second conveyor through a rib plate, at least two sets of wheel frames are provided on the outside of the top hopper and the middle hopper, pulleys are provided on the wheel frames, and slide grooves cooperating with the pulleys are provided on the inside of the middle hopper and the tail hopper.

[0005] In a preferred solution, baffles are provided at both ends of the slide groove to limit the pulley.

[0006] In a preferred solution, the top bucket, middle bucket and tail bucket are configured as conical cylinders that are larger at the top and smaller at the bottom.

[0007] In the preferred solution, the wheel frame includes a connecting tube, a connecting rod is slidably installed in the connecting tube, an end of the connecting tube away from the connecting rod is connected to the outside of the middle bucket, a pulley is provided at the end of the connecting rod, a limiting ring plate is provided on the outside of the connecting tube and the connecting rod, and a tightening spring is provided between the two sets of limiting ring plates.

[0008] The telescopic transfer hopper provided by the utility model has the following beneficial effects:

[0009] 1. The discharge end of the first conveyor is connected to the top bucket, and the second conveyor is connected to the tail bucket. When the height of the second conveyor changes due to the casting height requirement, the height difference between the first conveyor and the second conveyor changes. At this time, the rotating hopper of the utility model expands and contracts, and the multi-section intermediate buckets are relatively displaced to meet the material guiding requirements when the height changes.

[0010] 2. The top hopper, middle hopper and tail hopper are configured as tapered cylinders that are larger at the top and smaller at the bottom, which can effectively guide the concrete in the top hopper or middle hopper of the upper layer to the middle hopper or tail hopper of the lower layer.

[0011] 3. By setting a tightening spring, the pulley can always be set close to the slide groove during the up and down movement of the intermediate bucket, preventing the separation of two adjacent groups of intermediate buckets. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solution of the present utility model will be further described below with reference to the accompanying drawings.

[0018] like Figures 1-3As shown, a telescopic material transfer hopper includes a top hopper 1 and a tail hopper 3. A multi-section intermediate hopper 2 is provided between the top hopper 1 and the tail hopper 3. The multi-section intermediate hoppers 2 are nested with each other, with the top hopper 1 nested within the top intermediate hopper 2 and the bottom intermediate hopper 2 nested within the tail hopper 3. The top hopper 1, the multi-section intermediate hopper 232, and the tail hopper 3 nest together to form a telescopic cylinder structure. The top hopper 1 is fixedly connected to the truss of the upstream first conveyor 10 via a support frame 4, and the tail hopper 3 is fixedly connected to the truss of the downstream second conveyor 11 via a rib 5. At least two sets of wheel frames 6 are provided on the outside of the top hopper 1 and the intermediate hopper 2. The wheel frames 6 are provided with pulleys 7. The rotating shafts of the pulleys 7 are rotatably mounted on the wheel frames 6 via bearings. The intermediate hoppers 2 and the tail hopper 3 are provided with chute 8 that cooperate with the pulleys 7 to limit the movement of the pulleys 7. The relative movement of the multi-section intermediate hoppers 2 adjusts their overlapping length, so that the material transfer can be freely extended and retracted in the height direction.

[0019] Preferably, baffles 9 are provided at both ends of the chute 8 to limit the pulley 7. By providing the baffles 9, when the pulley 7 moves to the end of the chute 8, the pulley is prevented from disengaging from the chute 238 and causing the adjacent two groups of intermediate buckets 232 to disengage.

[0020] In this embodiment, the top hopper 1, middle hopper 2 and tail hopper 3 are configured as conical cylinders that are larger at the top and smaller at the bottom, which can effectively guide the concrete in the upper top hopper 1 or middle hopper 2 to the lower middle hopper 2 or tail hopper 3.

[0021] Preferably, Figure 3 As shown, the wheel frame 6 includes a connecting tube 601, a connecting rod 602 is slidably installed in the connecting tube 601, and the end of the connecting tube 601 away from the connecting rod 602 is connected to the outside of the middle bucket 2. A pulley 7 is provided at the end of the connecting rod 602, and a limiting ring plate 603 is provided on the outside of the connecting tube 601 and the connecting rod 602. A tightening spring 604 is provided between the two sets of limiting ring plates 603.

[0022] In this embodiment, the top bucket 1, the middle bucket 2 and the tail bucket 3 are configured as conical cylinders that are larger at the top and smaller at the bottom. By providing a tightening spring 604, the pulley 7 can always be set close to the slide groove 8 during the up and down movement of the middle bucket 2, preventing the two adjacent groups of middle buckets 232 from detaching.

[0023] During specific use, the discharge end of the first conveyor 10 is connected to the top bucket 1, and the second conveyor 11 is connected to the tail bucket 3. When the height of the second conveyor 11 changes due to the casting height requirement, the height difference between the first conveyor 10 and the second conveyor 11 changes. At this time, the rotating hopper of the utility model expands and contracts, and relative displacement occurs between the multi-section intermediate buckets 2 to meet the material guiding requirements when the height changes.

[0024] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limiting the present invention. The scope of protection of the present invention should be the technical solutions described in the claims, including equivalent replacement solutions of the technical features in the technical solutions described in the claims. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. That is, equivalent replacement improvements within this scope are also within the scope of protection of the present invention.
