Description

Technical Field

[0001] The invention relates to the technical field of mixers, and in particular to a gear ring anti-fracture type mixer. Background Art

[0002] Mixers are particularly suitable for uniformly mixing building materials, such as concrete.

[0003] Taking the invention patent with application number 201210346337.9 as an example of the prior art, the invention discloses a concrete mixer, including a base frame, the base frame supports a mixing barrel through rollers, and the mixing barrel is provided with a material port, and at the same time, a motor is provided on the base frame, the mixing barrel and the motor are connected in power, the base frame is provided with a column, the motor is fixed on the column, and the motor is located above the highest point of the material port. After optimization, the height difference △ between the lowest point of the motor and the highest point of the material port is: △ ≥ 500mm; the motor and the mixing barrel are driven by gears. The invention has the advantages that the motor is not easy to short-circuit and is safer to use.

[0004] It can be seen that the motor and the mixing barrel of the invention are mainly driven by gears. Specifically, a gear ring is mounted on the mixing barrel, and then a gear is set on the output shaft of the motor for meshing transmission. However, the diameter of the mixing barrel is relatively large, resulting in a relatively large diameter of the gear ring mounted on the mixing barrel, which makes the gear ring easy to break during transportation and practical use, resulting in poor durability and low economic benefits.

[0005] It is easy for technicians in this field to think of replacing the gear ring with a belt for transmission. Although the belt will not break during transportation, the mixer needs to be transported at various construction sites, and the mixing barrel and the base frame can only be movably connected. Therefore, in practice, the various parts are generally disassembled and transported to ensure the safety of each transportation.

[0006] During this disassembly process, the meshing of the ring gear and the gear only needs to be manually placed and slightly adjusted, but the belt drive is more difficult to install (due to the additional tensioning step of the belt). Summary of the invention

[0007] The object of the present invention is to provide a gear ring anti-breakage mixer to solve the technical problems in the prior art that the gear breakage problem can be improved and the belt-driven mixer is inconvenient to disassemble and assemble.

[0008] The present invention provides a gear ring anti-breakage type mixer, comprising a base frame and a mixing chamber, wherein the mixing chamber is rotatably mounted on the upper end of the base frame, at least two support rings are fixedly sleeved on the outer peripheral wall of the mixing chamber, and a plurality of traveling meshing columns whose axes are parallel to the axis of the mixing chamber are equidistantly arranged between two adjacent support rings;

[0009] A driving structure is provided on the chassis, and the driving structure is meshed and driven by a whole formed by a driving gear and a plurality of traveling meshing columns;

[0010] The support ring is a ring structure formed by welding a plurality of arc-shaped stamping plates end to end in sequence, and the traveling engagement column is a solid column structure formed by cutting steel bars.

[0011] Furthermore, a mounting hole is provided on the arc-shaped stamping plate, and the traveling engagement column is used to penetrate into the mounting hole and be fixed on the mounting hole by welding.

[0012] Furthermore, the outer peripheral wall of the stirring chamber is also sleeved with at least two parallel tracks, and the bottom frame is provided with rollers with grooves for cooperating with the tracks for limiting the position.

[0013] Furthermore, the track is a ring structure 2 formed by bending a welded pipe and welding the ends.

[0014] Furthermore, the base frame includes a main body, the upper surface of the main body presents a supporting structure that matches the curvature of the stirring chamber, and vertical frames are provided on both sides of the supporting structure, and the distance between the two vertical frames is not less than the maximum outer diameter of the stirring chamber;

[0015] A slide which can reciprocate along the axis of the stirring chamber is installed at the top of the vertical frame through a slide groove. A rotating shaft is rotatably installed on one side of the slide close to the stirring chamber, and a roller with a groove is arranged on the rotating shaft.

[0016] Further, a support mounting plate is provided on one side of one of the stands;

[0017] The driving structure includes a motor fixedly mounted on a supporting mounting plate, the output shaft of the motor passes through one side of the supporting mounting plate and is transmitted to the rotating shaft on the stand through a pulley transmission structure, and the driving gear is fixedly sleeved on the rotating shaft on the stand.

[0018] Furthermore, the supporting structure is provided with grooves for avoiding the rail, the support ring, and the travel engagement column.

[0019] Furthermore, a buckle structure is provided between two adjacent arc-shaped stamping plates.

[0020] Furthermore, a linear telescopic structure is connected between the slide and the stand.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] (1) Through the cooperation of the traveling meshing column and the two support rings, a tooth structure similar to the gear ring is formed. This scheme has two effects: first, it is more solid than the gear ring; second, it is easy to obtain materials and simple to install, and can be used as an emergency replacement when the gear ring suddenly breaks.

[0023] (2) The present invention does not need to drive the stirring chamber through a belt drive, and the present invention can store the stirring chamber, and then fit the bottom of the stirring chamber through a supporting structure, so that the stirring chamber can be relatively stably fixed in the base frame, ensuring that the stirring chamber will not roll down easily during transportation and saving space occupied during transportation.

Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] The present invention aims to improve the problem of gear breakage① and the problem of inconvenient assembly and disassembly of a belt-driven mixer②.

[0037] Regarding the problem of gear breakage①, Figure 1 As shown, the gear ring anti-fracture mixer mainly provides a solution to replace the gear ring that is prone to cracking: the gear ring anti-fracture mixer includes a base frame 1 and a stirring chamber 2, the stirring chamber 2 is rotatably installed on the upper end of the base frame 1, and the outer peripheral wall of the stirring chamber 2 is fixedly sleeved with at least two support rings 3, and a plurality of traveling meshing columns 4 with axes parallel to the axis of the stirring chamber 2 are equidistantly provided between two adjacent support rings 3; a driving structure 5 is provided on the base frame 1, and the driving structure 5 is meshed with the whole formed by the driving gear 6 and the plurality of traveling meshing columns 4 for transmission; the support ring 3 is an annular structure formed by a plurality of arc-shaped stamping plates 31 welded end to end in sequence, and the traveling meshing column 4 is a solid cylindrical structure formed by cutting steel bars.

[0038] The support ring 3 is formed by welding a plurality of arc-shaped stamped plates 31 end to end in sequence, and the arc-shaped stamped plates 31 are generally stamped iron plates (ordinary plates), and the traveling engagement column 4 is cut by steel bars to be relatively firm.

[0039] Through the cooperation of the traveling meshing column 4 and the two supporting rings 3, a tooth structure similar to the gear ring is formed. This solution has two effects: first, it is more solid than the gear ring; second, it is easy to obtain materials and simple to install, and can be used as an emergency substitute when the gear ring suddenly breaks.

[0040] In order to enhance the strength of the connection between the travel engagement column 4 and the two support rings 3, as well as the overall structural stability formed by them, it is preferred that:

[0041] A mounting hole is provided on the arc-shaped stamping plate 31, and the traveling engagement column 4 is used to penetrate into the mounting hole and be fixed on the mounting hole by welding.

[0042] Generally speaking, the track 7 for guiding the stirring chamber 2 generally has a die-cast iron ring, and this die-cast iron ring also has a risk of breakage, so it is preferred that:

[0043] The outer wall of the stirring chamber 2 is also sleeved with at least two parallel tracks 7, and the base frame 1 is provided with a grooved roller 8 for cooperating with the track 7 for limiting the position; the track 7 is a ring structure 2 formed by bending a welded pipe and welding the ends.

[0044] like Figure 4 As shown, the problem of gear breakage① is further extended, and a buckle structure 10 is provided between two adjacent arc-shaped stamping plates 31. The buckle structure 10 can generally pre-assemble the arc-shaped stamping plates 31 before welding, and can improve the strength of the overall structure after welding is completed.

[0045] It is also possible to stagger two adjacent arc-shaped stamping plates 31 so that they partially overlap, and one mounting hole of the overlapping portion coincides with the other, so that the traveling engagement column 4 can be inserted into the overlapping mounting hole by the bracket for pre-assembly and structural reinforcement, which is similar to the effect of the embodiment of the above-mentioned buckle structure 10.

[0046] In view of the inconvenience of disassembly and assembly of the belt-driven mixer②, this gear ring anti-fracture mixer ensures the firmness of the transmission structure while making it easy to disassemble and install like the existing mixer with a gear ring transmission structure. However, in order to further improve the convenience of installation and disassembly, this gear ring anti-fracture mixer provides the following solutions:

[0047] like Figure 2 and Figure 3As shown, the bottom frame 1 of the gear ring anti-fracture mixer includes a main body 11, the upper surface of the main body 11 presents a supporting structure 12 that matches the curvature of the mixing chamber 2, and both sides of the supporting structure 12 are provided with a stand 13, and the distance between the two stands 13 is not less than the maximum outer diameter of the mixing chamber 2; the top of the stand 13 is provided with a slide 15 that can reciprocate along the axis of the mixing chamber 2 through a slide 14, and the slide 15 is rotatably installed with a rotating shaft 16 on the side close to the mixing chamber 2, and the grooved roller 8 is arranged on the rotating shaft 16. A support mounting plate 17 is provided on one side of one of the stands 13; the driving structure 5 includes a motor 51 fixedly mounted on the support mounting plate 17, the output shaft of the motor 51 passes through one side of the support mounting plate 17 and is transmitted to the rotating shaft 16 on the stand 13 through a pulley transmission structure 52, and the driving gear 6 is fixedly sleeved on the rotating shaft 16 on the stand 13. The supporting structure 12 is provided with grooves for avoiding the track 7, the support ring 3, and the traveling meshing column 4. A linear telescopic structure 9 is connected between the slide 15 and the stand 13 .

[0048] The gear ring anti-breakage mixer first installs the motor 51 on the slide 15 through the support mounting plate 17, so that the driving structure 5 can move horizontally with the left slide 15, and then the grooved roller 8 and the driving gear 6 are installed on the slides 15 on both sides through the rotating shaft 16, so that the grooved rollers 8 on both sides can move towards or away from each other.

[0049] When the grooved rollers 8 on both sides are close to each other, the distance between the grooved rollers 8 on both sides becomes smaller (such as Figure 3 ), the grooved rollers 8 on both sides squeeze the stirring chamber 2 against each other so that the stirring chamber 2 rises and becomes an assembled state, so that normal stirring can be performed.

[0050] When the grooved rollers 8 on both sides are away from each other, the distance between the grooved rollers 8 on both sides becomes larger (such as Figure 2 ), the stirring chamber 2 can slowly descend along the grooved rollers 8 on both sides to become a storage state, and then the bottom of the stirring chamber 2 is fitted through the supporting structure 12, so that the stirring chamber 2 can be relatively stably fixed in the base frame 1, ensuring that the stirring chamber 2 will not roll down easily during transportation and saving space occupied during transportation.

[0051] When the grooved rollers 8 on both sides squeeze the stirring chamber 2 against each other to make the stirring chamber 2 rise, the driving gear 6 on the left rotating shaft 16 may be meshed with the whole formed by the multiple traveling meshing columns 4, or may not be meshed. However, since the stirring chamber 2 is not locked, the stirring chamber 2 can be manually lifted for adjustment.

[0052] The linear telescopic structure 9 drives the slide 15 to slide horizontally. The linear telescopic structure 9 can be a linear motor or a linear cylinder.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
