Description

Technical Field

[0001] This utility model relates to the field of mixer arm technology, specifically to a mixer arm and installation structure for a mixing device that is easy to scrape materials. Background Technology

[0002] A concrete mixer is a machine that mixes cement, sand, aggregates, and water to produce concrete. It mainly consists of a mixing drum, feeding and unloading mechanisms, a water supply system, and a prime mover. Based on the nature of operation, it can be classified as intermittent or continuous; based on the structure of the mixing drum, it can be classified as pear-type, drum-type, double-cone, disc-type vertical shaft, and groove-type horizontal shaft, etc.

[0003] The stirring arm is mounted on the stirring spindle, and is conventionally fixed at the end of the stirring arm with bolts.

[0004] For example, references CN201510171458.8 and CN201420114270.0 describe a mixing arm for a concrete mixer. However, the aforementioned mixing arms are mostly installed in a conventional manner, and the angle of the mixing blades on the mixing arm is not adjustable. This may result in insufficient mixing effect for different types of concrete. The following situations require adjustable mixing blade angles:

[0005] 1) Blade deformation or displacement: If the blade is subjected to abnormal impact, excessive wear, or loose fixing bolts, the blade may change in its installation position and angle. In this case, correction is required to restore it to its original design angle.

[0006] 2) Special working conditions: In special circumstances, such as when the characteristics of the materials being mixed are very different from those of conventional concrete, such as viscosity, density, and particle size, it may be necessary to fine-tune the blade angle to adapt to the new working conditions.

[0007] To address these issues, we provide a mixing arm and installation structure for an easy-to-scrape mixing device. Utility Model Content

[0008] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a mixing arm and installation structure for a mixing device that is easy to scrape materials, so as to solve the technical problem of insufficient applicability caused by the inability to adjust the angle.

[0014] The square columns located on both sides of the long arm plate have insertion cavities, and the insertion cavities extend to the outside of the square columns and have arc-shaped grooves. The arc-shaped grooves are symmetrically arranged on both sides of the square columns and are detachably fitted with locking components for locking the stirring blades.

[0015] In a further technical solution, the square column has an arc-shaped surface on the side facing the long arm plate, and the arc-shaped surface and the arc-shaped groove are arranged with the same center.

[0016] In a further technical solution, the two ends of the arc-shaped groove extend to the top surface of the square column and are provided with air passages, and a removable plug is provided at the end of the air passage.

[0017] In a further technical solution, an angle limiting plate is installed on the surface of the square column, a position hole is opened on one side of the angle limiting plate, and it is fixed to the square column by positioning bolts;

[0018] A limiting groove is provided on the angle limiting plate, which is used to limit the position of the locking element within the arc-shaped groove.

[0019] In a further technical solution, the clamping part includes a polygonal bent surface, and a strip-shaped groove is provided on each bent surface along the axial direction.

[0020] An easy-to-scrape material mixing device mixing arm mounting structure is provided, wherein a set of connecting holes are provided on the long arm plate; the mixing blade includes a working part and a connecting clamp plate, the width of the working part being greater than the length of the long arm plate; the connecting clamp plate is snapped onto the long arm plate and inserted into the insertion cavity; an angled hole is provided at the end of the connecting clamp plate away from the working part, the angled hole being suitable for a locking element to pass through.

[0051] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0052] Figure 1 The existing stirring arm has an arc-shaped bottom and a long rod at the top, with a waist-shaped hole on the long rod for connecting the stirring blades.

[0053] Example 1

[0054] Please see Figure 2-5 This utility model provides a technical solution: a stirring arm for an easy-to-scrape mixing device, comprising:

[0055] like Figure 2 As shown, the arc-shaped body 1 has a clamping part 12 at its bottom and positioning holes 13 on both sides of the arc-shaped body 1; a set of arc-shaped bodies 1 combined with another set of arc-shaped bodies can be assembled and installed on the stirring main rod.

[0056] The long rod body 2 is integrally formed with the arc-shaped body 1; a connecting hole 21 is provided on the long rod body 2; the connecting hole 21 is used to connect the stirring blade 10;

[0057] The long rod 2 includes a square column 3 and a long arm plate 4. The thickness of the long arm plate 4 is relatively smaller than that of the long rod. The square column 3 is integrally connected to the arc-shaped body 1. The long arm plate 4 is fixedly connected to the side of the square column 3 facing away from the arc-shaped body 1. A connection hole 21 is provided on the long arm plate 4.

[0058] like Figure 2 As shown, the square columns 3 located on both sides of the long arm plate 4 have insertion cavities 31, and the insertion cavities 31 extend to the outside of the square columns 3, where arc-shaped grooves 32 are formed. The arc-shaped grooves 32 are symmetrically arranged on both sides of the square columns 3 and are detachably fitted with locking parts 5 for locking the stirring blades 10. Figure 4 The working part of the mixing blade is located at the top of the diagram and is deflected at a certain angle relative to the long rod, which is beneficial for rotating and mixing concrete.

[0059] like Figure 5 As shown, the two ends of the arc-shaped groove 32 extend to the top surface of the square column 3 and are provided with air passages 34, and a detachable plug 35 is provided at the end of the air passage 34. The air passage is used to remove the mixing arm after the machine is stopped, open the plug and pressurize with high pressure to force the concrete that has not yet fully solidified out of the arc-shaped groove and into the insertion cavity, so as to facilitate maintenance and cleaning.

[0060] like Figure 2 and 3 As shown, the clamping part 12 includes a polygonal bent surface, and each bend along the axial direction has a strip-shaped groove 14. The strip-shaped groove design makes it easier to avoid being completely absorbed or solidified by concrete when installed on the mixing shaft, thus reducing the likelihood of technical problems such as difficulty in removing the mixing arm.

[0061] The arc-shaped body is mounted on the mixing shaft and assembled using the mounting bracket. The mixing blades are pre-installed, and their angle within the arc-shaped groove is adjusted to facilitate contact with the inner wall of the mixing equipment, thus aiding in material scraping. Finally, the angle and position of the mixing blades are fixed using locking components and positioning bolts installed in the connecting holes.

[0062] This invention features a plug-in cavity and an arc-shaped groove. The mixing blade is installed within the plug-in cavity, and a set of connecting holes provides initial positioning. A locking mechanism is installed to adjust the angle of the mixing blade on the long arm plate before locking, and then the locking mechanism secures the blade, fixing the angle. The adjustable mixing blade is more suitable for handling complex concrete mixing and wear-prone conditions. The air passage designed in this invention facilitates easy cleaning.

[0063] Example 2

[0064] like Figure 6-8 In another embodiment of this utility model, based on embodiment 1, an angle limiting plate 6 is installed on the surface of the square column 3, such as... Figure 8 As shown, a position hole is opened on one side of the angle limiting plate 6, and it is fixed to the square column 3 by positioning bolts 61;

[0065] An angle limiting plate 6 is provided with a limiting groove 62, which is used to limit the position of the locking member 5 in the arc groove 32. Figure 6 A schematic diagram of the actual use of the stirring arm;

[0066] This embodiment uses an angle limiting plate installed on the long rod to limit and fix the angle of the locking component, ensuring that the mixing blades on the mixing arm will not change angle under the impact of concrete inside the mixer, thus preventing interference and damage to the inner wall of the mixer.

[0067] Example 3

[0068] like Figure 9 As shown, another embodiment of the present invention is provided. Based on embodiment 2, the square column 3 is provided with an arc-shaped surface 33 on the side facing the long arm plate 4, and the arc-shaped surface 33 and the arc-shaped groove 32 are arranged with the same center.

[0069] This embodiment uses an arc-shaped surface for quick positioning. When a limiting post (not shown) is installed on the stirring blade, it can be directly snapped onto the arc-shaped surface, thus confirming that the bottom of the stirring blade is inserted into the insertion cavity, facilitating the installation of the locking component.

[0070] Example 4

[0071] like Figure 10-13As shown, this is another embodiment of the present invention. Based on embodiment 2, an easy-to-scrape material mixing arm mounting structure is provided, with a set of connecting holes 21 on the long arm plate 4; the mixing blade 10 includes a working part 101 and a connecting clamping plate 102, the width of the working part 101 being greater than the length of the long arm plate 4, as shown. Figure 10 As shown, the width of the bottom connecting clamp is adapted to be installed on the long arm plate; the connecting clamp 102 is snapped onto the long arm plate 4 and inserted into the insertion cavity 31; an angle hole 103 is provided at the end of the connecting clamp 102 away from the working part 101, and the angle hole 103 is suitable for the locking member 5 to pass through.

[0072] like Figure 13 As shown, the arc-shaped body 1 is used to be installed on the stirring spindle 20, and a reserved groove 15 is provided on the arc-shaped body 1 on both sides of the axis of the stirring spindle 20.

[0073] The stirring arm located at the end of the stirring main shaft 20 has a sealing ring 7 detachably installed in the reserved groove 15; the outer diameter of the sealing ring 7 is larger than the inner diameter of the mounting hole 30 of the stirring main shaft 20 in the stirring equipment.

[0074] Combination Figure 12 and 13 As shown, the sealing ring 7 includes a ring edge portion 71 and a mounting portion 72. The mounting portion 72 is fixed in the reserved groove 15 by a lateral bolt 73. The end of the cross-section of the mounting portion 72 is shaped like an upward-facing "C". This invention, by installing the sealing ring at the mounting hole of the corresponding mixing equipment, ensures that concrete will not enter the mounting hole due to lateral closure, thus preventing concrete from filling and bonding the mixing spindle at the mounting hole. One end of the mounting portion of the sealing ring is connected to the reserved groove, and the other end extends through the ring edge portion to cover the mounting hole.

[0075] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
