Description

Technical Field

[0001] The utility model relates to the technical field of feed hoppers, in particular to a rubber powder feed hopper. Background Art

[0002] In the processing of highway paving materials, glue powder (such as rubber powder) is used as an additive. It is generally lifted from a low place to a high place by a hoist, and then put into the processing equipment (such as a mixing tank). However, the glue powder is very easy to absorb moisture and clump during storage and transportation, which will eventually lead to quality problems in the processed paving materials (the clumped glue powder will aggregate with other materials during the processing after addition, forming larger clumps, resulting in uneven final paving materials). Therefore, in the prior art, the glue powder generally needs to be filtered before being put into the processing equipment to avoid the adverse effects caused by clumping. However, the clumped glue powder cannot be utilized, so it is necessary to break up the clumped glue powder again and then add it to avoid waste, thereby reducing the overall processing efficiency.

DETAILED DESCRIPTION

[0024] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0025] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0026] In an exemplary embodiment, Figure 1-5 As shown, the present embodiment provides a rubber powder feeding hopper, which includes a hopper body 1, the upper end of the hopper body 1 is a feeding port 2, and the lower end is a discharging port 3; it also includes a vertical cylinder 4 connected to the discharging port 3, a filter screen 5 is fixedly connected to the vertical cylinder 4 to separate it into upper and lower parts, and a mounting shaft 6 is rotatably installed in the vertical cylinder 4 and is located above the filter screen 5 and parallel to the filter screen 5, and a plurality of beating blades 7 are fixedly connected to the mounting shaft 6; a driving motor 8 for driving the mounting shaft 6 is also installed outside the vertical cylinder 4; a distribution plate 9 is also provided in the hopper body 1 to separate it into upper and lower parts, and a connecting port 10 staggered with the discharging port 3 is also provided on the distribution plate 9.

[0027] In the above embodiment, the feed port 2 is used to introduce materials into the hopper body 1 (i.e., rubber powder), and the lower end of the vertical cylinder 4 is used to discharge materials. The filter screen 5 arranged in the vertical cylinder 4 is similar to the prior art and is used to intercept agglomerated materials. The provided beating blades 7 can break up the agglomerated materials under the drive of the driving motor 8, and then move downward through the filter screen 5. The agglomerated materials do not need to be taken out and can be fed normally, thus solving the problem in the prior art that the agglomerated rubber powder needs to be broken up again and then added, resulting in a decrease in the overall processing efficiency. Specifically, the lower end of the vertical cylinder 4 in this solution is also connected to the feed end 11 of the elevator in the prior art, so that the materials can be smoothly introduced into the elevator, and then directly fed after being lifted, avoiding moisture absorption again in the intermediate link.

[0028] In a more optimal solution, the filter screen 5 can be arc-shaped, and the axis of the installation shaft 6 is coincident with the center line of the arc, so that the beating blades 7 installed on the installation shaft 6 can be as close to the filter screen 5 as possible (but not in contact with it), thereby continuously turning the material during the rotation of the installation shaft 6 to achieve efficient breakup, and the agglomerated materials and normal non-agglomerated materials after breakup are more likely to pass through the filter screen 5 during the turning process, and the passing efficiency is better.

[0029] like Figure 1-4 As shown, in a further exemplary embodiment, a plurality of positioning grooves 12 corresponding to each whipping blade 7 are recessed on the side wall of the mounting shaft 6, and the whipping blade 7 includes a blade 23 and a positioning block 13 that can be accommodated in the positioning groove 12. Furthermore, the whipping blade 7 can be detachably mounted, that is, the installation with the mounting shaft 6 is realized by a bolt 16, which can facilitate maintenance, and the positioning holes can provide positioning for each whipping blade 7, making the installation better, more efficient and convenient;

[0030] More specifically, the beating blade 7 further includes a mounting plate 14 fixedly connected to the blade 23, the positioning block 13 is fixedly connected to the mounting plate 14, and a screw hole 15 is further provided on the mounting shaft 6 next to each positioning groove 12 for connection with a bolt 16, and the bolt 16 is specifically connected between the mounting plate 14 and the screw hole 15;

[0031] In order to optimize the arrangement of the beating blades 7, all the positioning grooves 12 are arranged in a spiral shape on the mounting shaft 6, and the corresponding beating blades 7 are also arranged in a spiral shape.

[0032] like Figure 1 , 5As shown, in a further exemplary embodiment, the distribution plate 9 includes a pair of connecting plates 17 respectively abutting against the inner wall of the hopper body 1, and a baffle plate 18 fixedly connected to the two connecting plates 17 and located directly above the discharge port 3, and the connecting port 10 includes at least two respectively arranged on the two connecting plates 17. In this scheme, after the material enters the hopper body 1, it continues to move downward through the connecting port 10 staggered with the discharge port 3, so that the distribution plate 9 can block part of the material splashed during the dispersion process to prevent the material from flying outward, and the distribution plate 9 is arranged as two connecting plates 17 and a baffle plate 18, and the discharge port 3 is arranged on the connecting plate 17, and the material enters the bottom from both sides more smoothly; further to avoid the accumulation and retention of materials on the distribution plate 9, the two connecting plates 17 are inclined and the lower ends are close to each other, and the outer edges of the two ends of the baffle plate 18 are respectively connected to the lower edges of the connecting port 10 arranged on the two connecting plates 17, so that the material can pass through the connecting port 10 more smoothly, and a better scheme is to set the baffle plate 18 as an upward convex arc structure, and the material on the baffle plate 18 is diverted to both sides, so that it will not be retained;

[0033] In more detail, the connecting plate 17 is also fixedly connected to an inclined abutment plate 19, and the inclined abutment plate 19 can abut against the inner wall of the hopper body 1. Specifically, the inner wall of the feed hopper body 1 is also an inclined four-sided structure, so that the two abutment plates 19 abut against two of the inner walls facing each other, so that the cloth plate 9 can be stabilized in the hopper body 1. At the same time, the cloth plate 9 can also be disassembled, which is convenient for subsequent inspection and maintenance.

[0034] like Figure 1 As shown, in a further exemplary embodiment, the upper end of the hopper body 1 is also fixedly connected to a ring plate 20 surrounding the outside of the feed port 2, and a baffle 22 is also fixedly connected to the ring plate 20 to form a fence with a side opening 21 thereon. The set ring plate 20 can provide a place for the rubber powder packaging bag to lean against when the material is fed into the feed port 2, thereby facilitating the operation, and the fence with the side opening 21 prevents the thrown material from accidentally overflowing and causing waste.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
