Description

Technical Field

[0001] The utility model relates to the technical field of asphalt mixing, in particular to a cold material hopper. Background Art

[0002] The cold hopper of the asphalt mixing plant is mainly used to transport cold aggregates of various specifications and sizes through several cold hoppers in a certain ratio to the drying barrel for aggregate heating. A layer of primary filter iron mesh is set at the upper end (inlet end) of each cold hopper, which is mainly used to screen out some unqualified large aggregates in the cold aggregates to prevent them from entering the conveyor belt at the lower end of the cold hopper, causing the conveyor belt and the lower end of the cold hopper to get stuck and unable to operate normally.

[0003] For example, publication number CN218432915U discloses a cold material hopper of an asphalt mixing plant, including an external frame, which is frame-shaped, and a plurality of groups of detachable primary filter iron rods are arranged inside the external frame, and a crossbeam is fixedly installed inside the external frame corresponding to the lower part of the primary filter iron rod, and the crossbeam corresponds to the middle area of the primary filter iron rod, and two mirror-inclined support rods are fixedly installed on the wall below the crossbeam, and the ends of the two support rods facing away from each other are fixedly connected to the inner wall of the external frame, and the crossbeam and the support rod are arranged to support the middle sections of the plurality of groups of primary filter iron rods, thereby reducing the deformation of the middle ends of the primary filter iron rods caused by continuous impact of aggregates, affecting the use, reducing the difficulty of operation, and avoiding economic losses.

[0004] Based on the search of patent numbers and combined with the deficiencies in the prior art, it is found that:

[0005] Although the cold hopper of the asphalt mixing plant reduces the deformation of the middle end of the primary filter iron rod caused by the continuous impact of aggregates, during use, the aggregates will collide with the primary filter iron rod to varying degrees when falling, so the primary filter iron rod is prone to deformation after long-term use, and needs to be replaced regularly by users. The primary filter iron rod in the cold hopper is mainly positioned by the slot and the block. The vibration transmitted from the primary filter iron rod to the block can easily cause the block and the slot to get stuck, and each primary filter iron rod needs to be disassembled separately, which is time-consuming.

The primary filter iron rod in the cold material hopper is mainly positioned by the slot and the block. The vibration transmitted from the primary filter iron rod to the block can easily cause the block and the slot to get stuck, and each primary filter iron rod needs to be disassembled separately, which is time-consuming.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] As Figures 1 to 3 shown, a cold hopper provided by the present utility model includes a frame 1 and a primary filter iron rod 2. The primary filter iron rod 2 is located inside the frame 1. Limiting holes 3 are opened at the tops of the left and right inner walls of the frame 1. The number of the limiting holes 3 is twice that of the primary filter iron rod 2. The inner walls of the limiting holes 3 are movably connected to the surfaces of both ends of the primary filter iron rod 2. A connecting component 4 is fixedly connected to one end of the primary filter iron rod 2 close to the left side of the frame 1. A positioning mechanism 5 is movably connected to the front side of the frame 1.

[0023] Referring Figure 3 , the connecting component 4 includes a mounting plate 41. The left side of the mounting plate 41 is fixedly connected with a movable frame 42 by bolts. The movable frame 42 is arranged in an L shape. The rear side of the inner wall of the movable frame 42 is movably connected to the rear side of the frame 1.

[0024] As a technical optimization scheme of the present utility model, by setting the connecting component 4, the movable frame 42 can fix and limit the mounting plate 41. The fixed limit of the mounting plate 41 can fix and limit the primary filter iron rod 2. By moving the movable frame 42 to the left, the mounting plate 41 and the primary filter iron rod 2 can be driven to move to the left, so that the primary filter iron rod 2 can be separated from the limiting hole 3 and the frame 1. At this time, the user can replace the primary filter iron rod 2 by screwing out the bolts connecting the mounting plate 41 and the movable frame 42.

[0025] Referring Figure 2 and Figure 3 , the positioning mechanism 5 includes a connecting plate 51. The rear side of the connecting plate 51 is fixedly connected with a support plate 52. The rear side of the support plate 52 penetrates through the frame 1 and extends to the rear side of the frame 1. The support plate 52 is movably connected to the frame 1. The top of the support plate 52 is attached to the bottom surface of the primary filter iron rod 2. A groove 53 is opened at the rear side of the bottom of the movable frame 42. The rear side of the top of the support plate 52 is attached to the top of the inner wall of the groove 53. A rotating rod 54 is arranged at the rear side of the top of the movable frame 42. One end of the rotating rod 54 close to the support plate 52 sequentially penetrates through the movable frame 42 and the support plate 52 and extends to the bottom of the support plate 52. The rotating rod 54 is threadedly connected to the movable frame 42 and the support plate 52.

[0026] As a technical optimization solution of the present utility model, by providing a positioning mechanism 5, the support plate 52 can support the primary filter iron rod 2, thereby reducing the deformation of the primary filter iron rod 2 caused by the collision between the aggregate and the primary filter iron rod 2. The groove 53 enables the support plate 52 to limit the movement of the movable frame 42 left and right. By pulling the connecting plate 51, the support plate 52 can be driven to move back and forth, and the rotating rod 54 can position the support plate 52 and the movable frame 42, thereby improving the stability of the movable frame 42, the primary filter iron rod 2, and the support plate 52.

[0027] Reference Figure 3 , a sliding plate 6 is fixedly connected to the rear side of the inner wall of the movable frame 42, and a sliding groove 7 is formed at the top of the rear side of the frame 1. The surface of the sliding plate 6 is slidably connected to the inner wall of the sliding groove 7.

[0028] As a technical optimization solution of the present utility model, by providing the sliding plate 6 and the sliding groove 7, the left and right movement of the movable frame 42 can drive the sliding plate 6 to slide left and right inside the sliding groove 7. The sliding groove 7 can limit the movement of the sliding plate 6 and the movable frame 42 in the front-back, up-down directions, thereby improving the movement efficiency of the movable frame 42.

[0029] Reference Figure 3 , a fixing plate 8 is fixedly connected to the right side of the frame 1. Through holes 9 are formed in the right side of the fixing plate 8. The number of the through holes 9 is the same as that of the primary filter iron rods 2, and the inner wall of the through hole 9 is movably connected to the surface of the primary filter iron rod 2.

[0030] As a technical optimization solution of the present utility model, by providing the fixing plate 8 and the through holes 9, the through holes 9 enable the fixing plate 8 to support the right end of the primary filter iron rod 2, thereby improving the load-bearing capacity of the primary filter iron rod 2.

[0031] Reference Figure 1 , reinforcing plates 10 are fixedly connected to both the left and right sides of the frame 1. The bottoms of the movable frame 42, the mounting plate 41, and the fixing plate 8 are in contact with the tops of the reinforcing plates 10. Pulling grooves 11 are formed on the front side of the connecting plate 51 and the left side of the movable frame 42.

[0032] As a technical optimization solution of the present utility model, by providing the reinforcing plates 10 and the pulling grooves 11, the reinforcing plates 10 can support the movable frame 42, the mounting plate 41, and the fixing plate 8, thereby improving the stability of the movable frame 42, the mounting plate 41, and the fixing plate 8 when the aggregate collides with the primary filter iron rod 2. The pulling grooves 11 facilitate the user to pull the movable frame 42 and the connecting plate 51.

[0033] Working principle and usage process of the utility model: When in use, when it is necessary to disassemble and replace the primary filter iron rod 2, first rotate the rotating rod 54 to make it disengage from the support plate 52 and the movable frame 42 in sequence. At this time, the rotating rod 54 no longer positions the support plate 52. The user can drive the support plate 52 to move forward by pulling the connecting plate 51. When the support plate 52 moves away from the movable frame 42, the support plate 52 no longer limits the movable frame 42. The user can pull the movable frame 42, the mounting plate 41 and the primary filter iron rod 2 to move to the left through the pulling groove 11. When the primary filter iron rod 2 completely disengages from the frame 1, the user can disassemble and replace the mounting plate 41 and the primary filter iron rod 2 by unscrewing the bolts connecting the movable frame 42 and the mounting plate 41. The disassembly process is relatively convenient and efficient.

[0034] To sum up: For this cold hopper, by setting the limiting hole 3, the limiting hole 3 can perform movable limiting on the primary filter iron rod 2, thus facilitating the user to disassemble the primary filter iron rod 2, and solving the problem that since the aggregate will collide with the primary filter iron rod to varying degrees when falling, the primary filter iron rod is prone to deformation after long-term use and needs to be regularly replaced by the user. In this cold hopper, the primary filter iron rod is mainly positioned by the card slot and the clamping block, and the vibration conducted from the primary filter iron rod to the clamping block easily causes jamming between the clamping block and the card slot, and each primary filter iron rod needs to be disassembled separately, which is time-consuming.
