DETAILED DESCRIPTION

[0016] Example 1 like Figure 2-6 As shown, a support mortar making device comprises a cylinder 1 and an adjustable stirring mechanism 2, wherein the top of the cylinder 1 is open for installing the adjustable stirring mechanism 2 and pouring mortar raw materials, and the adjustable stirring mechanism 2 comprises a support frame 10 erected at the top opening of the cylinder 1, and a combined stirring rod 20 is rotatably arranged at the center of the support frame 10, and the combined stirring rod 20 is coaxial with the central axis of the cylinder 1. A driving device 30 for driving the combined stirring rod 20 to rotate is also arranged on the top of the support frame 10. During stirring, the driving device 30 is used to drive the combined stirring rod 20 to stir in the cylinder 1, thereby realizing automatic stirring of the mortar.

[0017] It should be noted that a support foot is provided at the top edge of the cylinder 1 for supporting and fixing the support frame 10, and the two can be fixed by bolts. The support frame 10 is welded from steel pipes, and a supporting steel plate is welded at the center. The driving device 30 is composed of a driving motor and a gear box transmission combination.

[0018] The combined stirring rod 20 includes an outer sleeve 21 whose top end is rotatably arranged on the support frame 10. The top end of the outer sleeve 21 passes through the support frame 10, and a driven gear 213 is arranged on the outside to be transmission-connected to the driving device 30. The driving device 30 is installed on the support frame 10 through a mounting frame 31, and a transmission gear 32 meshing with the driven gear 213 is arranged at its output end, so that the combined stirring rod 20 is driven to rotate by the driving device 30, and the connection between the support frame 10 and the outer sleeve 21 is rotatably connected through a bearing.

[0019] The outer sleeve 21 is rotatably provided with a plurality of stirring blade assemblies 22 located in the cylinder 1. In the present embodiment, a total of three stirring blade assemblies 22 are provided, each group of stirring blade assemblies 22 has four stirring blade assemblies, and the three groups of stirring blade assemblies 22 are staggered. The interior of the outer sleeve 21 is rotatably provided with an adjusting rod assembly 23 for adjusting the angle of the stirring blade assembly 22. The top of the support frame 10 is also provided with a control mechanism 24 for controlling the separation and combination of the outer sleeve 21 and the adjusting rod assembly 23. When in use, the connection and separation between the outer sleeve 21 and the adjusting rod assembly 23 can be realized through the control mechanism 24, and then the stirring blade assembly 22 can be adjusted by the rotation of the outer sleeve 21 independently of the adjusting rod assembly 23.

[0020] Furthermore, a mounting hole 210 for mounting the stirring blade assembly 22 is provided on the wall surface of the outer sleeve 21; The stirring blade assembly 22 includes a combined stirring blade 220, and the end of the combined stirring blade 220 is provided with a mounting shaft 221. The other end of the mounting shaft 221 can be rotatably passed through the mounting hole 210, and a rotating bevel gear 222 is provided. A bearing that is easy to rotate is provided at the connection between the mounting hole 210 and the mounting shaft 221. With this design, the stirring blade assembly 22 can adjust its own stirring angle by rotating.

[0021] Furthermore, the adjusting rod assembly 23 includes an internal adjusting rod 230 rotatably arranged in the outer sleeve 21 through multiple supporting bearings 231, and a plurality of connecting bevel gears 232 are arranged on the outside of the internal adjusting rod 230, corresponding to multiple groups of stirring blade assemblies 22 respectively, and the connecting bevel gears 232 are meshed with the rotating bevel gears 222 of all stirring blade assemblies 22 of the corresponding groups. In the present embodiment, the connecting bevel gear 232 is located above the rotating bevel gear 222.

[0022] When in use, when the outer sleeve 21 and the adjusting rod assembly 23 are connected as one piece through the control mechanism 24, they can be driven by the driving device 30 to realize overall rotation, thereby achieving the stirring effect. When the outer sleeve 21 is separated from the adjusting rod assembly 23, the outer sleeve 21 can be driven by the driving device 30 to rotate independently with the adjusting rod assembly 23, thereby making the stirring blade assembly 22 follow the rotation, and utilizing the rotating bevel gear 222 to rotate on the connecting bevel gear 232 to realize its own angle adjustment, thereby satisfying stirring at different angles.

[0023] Furthermore, the top of the outer sleeve 21 is open, and the top of the internal adjustment rod 230 passes through the opening at the top of the outer sleeve 21; The control mechanism 24 includes a fixed frame 247 arranged on the top of the support frame 10, and a telescopic cylinder 248 coaxial with the internal adjustment rod 230 is arranged at the center of the fixed frame 247. The telescopic end of the telescopic cylinder 248 passes through the fixed frame 247 and is rotatably connected to a lifting frame 244 movably sleeved on the end of the internal adjustment rod 230, so that the lifting frame 244 can be lifted and lowered by the telescopic cylinder 248. A conical connecting seat 240 is arranged on the outside of the internal adjustment rod 230, and its top is flush with the top of the outer sleeve 21. The cross section of the conical connecting seat 240 is narrow at the top and wide at the bottom. The bottom of the lifting frame 244 is provided with an inner conical plug-in groove 243 adapted to the conical connecting seat 240. When in use, the inner conical plug-in groove 243 is inserted into the gap between the conical connecting seat 240 and the outer sleeve 21, and the friction force of the contact surface is utilized to realize the connection between the outer sleeve 21 and the internal adjusting rod 230. At the same time, when the inner conical plug-in groove 243 is pulled out, the connection between the two can be contacted. At the same time, the rotatable connection between the telescopic cylinder 248 and the lifting frame 244 can avoid affecting the synchronous rotation of the outer sleeve 21 and the internal adjusting rod 230.

[0024] It should be noted that the fixing frame 247 includes four vertical poles and a top plate arranged on the four vertical poles. The top plate is provided with a hole for the telescopic cylinder 248 to pass through. The fixing frame 247 is erected directly above the internal adjustment rod 230.

[0025] Furthermore, the lifting frame 244 includes a top plate 245 and a bottom plate 242, and a plurality of connecting rods 244 are arranged at the edges between the top plate 245 and the bottom plate 242. In this embodiment, the number of the connecting rods 244 is four and they are evenly spaced. In addition, the spacing between the top plate 245 and the bottom plate 242 meets the height requirement of lifting on the internal adjustment rod 230. The outside of the protruding end of the internal adjustment rod 230 is provided with a plurality of lifting limit grooves 241. In this embodiment, the number of the lifting limit grooves 241 is four and they are evenly spaced. The bottom plate 242 is movably mounted on the outside of the internal adjusting rod 230 through the hole at the center thereof, and a lifting limit block 252 matching the lifting limit groove 241 is arranged on the inner wall surface of the hole. Such a design enables the lifting frame 244 to be stably lifted and lowered on the outside thereof while ensuring the docking accuracy of the inner conical plug-in groove 243. In addition, when the lifting frame 244 is lifted, the connection between the lifting limit block 252 and the lifting limit groove 241 can be utilized to limit the internal adjusting rod 230 and prevent it from rotating with the outer sleeve 21.

[0026] A connecting rotating seat 246 is provided on the top of the top plate 245, and a convex-shaped rotating groove is provided on the connecting rotating seat 246. A convex-shaped rotating connecting part 249 matching with the convex-shaped rotating groove is provided at the telescopic end of the telescopic cylinder 248. A bearing is provided at the connection between the convex-shaped rotating connecting part 249 and the convex-shaped rotating groove to make its rotation smoother. At the same time, the cooperation of the convex shape can achieve the lifting effect while rotating the connection.

[0027] The cross-section of the top plate 245 is tapered and narrow at the top and wide at the bottom. An inner conical annular groove 251 that can be matched with the top plate 245 is suspended on the fixed frame 247 by multiple suspension rods 250. In this embodiment, there are two suspension rods 250. When the lifting frame 244 is raised, it can be inserted into the inner conical annular groove 251, so as to achieve temporary fixation by utilizing the friction between the two, thereby restricting the internal adjustment rod 230 and allowing the outer sleeve 21 to rotate independently. The telescopic end of the telescopic cylinder 248 passes through the center hole of the inner conical annular groove 251.

[0028] In this embodiment, the bottom end of the internal adjustment rod 230 can be rotatably connected to the inner bottom wall of the outer sleeve 21 through a bearing, and the bottom of the outer sleeve 21 can be rotatably connected to the inner bottom wall of the cylinder 1 through a bearing, so that its rotation is more stable.

[0030] Telescopic grooves 2205 are provided on the two opposite inner wall surfaces of the outer sleeve blade 2200, specifically the upper and lower inner wall surfaces in the present embodiment. The insertion end of the telescopic blade 2201 is provided with a telescopic slider 2206 matching the telescopic groove 2205. The sliding connection between the telescopic slider 2206 and the telescopic groove 2205 can play a role of sliding limit.

[0031] The installation plug shaft 221 is fixedly arranged at the connection end between the outer sleeve 21 and the outer sleeve 21. The interior of the installation plug shaft 221 is hollow, and the two ends are open. A length adjustment rod 2202 is rotatably arranged therein. A bearing can be arranged at the connection between the plug shaft 221 and the length adjustment rod 2202 to make its rotation smoother. One end of the length adjustment rod 2202 extends into the telescopic blade 2201, and a threaded wire is arranged on the outside. The telescopic blade 2201 is threadedly connected with the threaded wire through a threaded hole 2204 arranged thereon. The other end of the length adjustment rod 2202 passes through the installation plug shaft 221 and the rotating bevel gear 222. There is an anti-rotation rectangular block 2203, and a support ring 211 is fixedly provided on the inner wall surface of the outer sleeve 21. The support ring 211 is provided with an anti-rotation rectangular sleeve 212 which is sleeved on the outside of the anti-rotation rectangular block 2203. The support ring 211 is located below the rotating bevel gear 222. Through the shape setting of the anti-rotation rectangular block 2203 and the anti-rotation rectangular sleeve 212, when the combined stirring blade 220 rotates, the length adjustment rod 2202 does not rotate, so that the telescopic blade 2201 can be telescoped through the rotation of the threaded hole 2204 on the threaded wire of the length adjustment rod 2202, thereby achieving the effect of adjusting the overall length of the combined stirring blade 220.

[0032] The support bearing 231 is disposed at the center hole of the support ring 211 , so that the support ring 211 can be used to fix the support bearing 231 .

[0033] It should be noted that the thread on the length adjustment rod 2202 and the pitch of the threaded hole 2204 should be as long as possible to achieve the maximum distance movement with the minimum number of rotations. In addition, before adjusting the angle of the stirring blade assembly 22, the length of the combined stirring blade 220 should be adjusted by rotation.

[0041] It should be noted that the numerical control display 5 is also provided with an alarm system, which can remind the operator when the preset mortar usage reaches a preset critical value. The numerical control display 5 is a mature existing technology, so it will not be described in detail here.

[0042] Example 5 Further illustrate with reference to Examples 1-5, Figure 1-12 The structure shown in FIG. 1 is a method for using the above-mentioned support mortar manufacturing device, the method comprising: S1. Initial rapid stirring. At this time, when the mortar is relatively thin and has good fluidity, the goal is to quickly mix the various components in the mortar. The mortar raw materials are poured into the barrel 1 according to the proportion, and the length of the stirring blade assembly 22 of the adjustable stirring mechanism 2 is fully extended to cover a larger stirring area, and its angle is adjusted to between 30-45° to increase the stirring range, and the telescopic teeth 2212 are in a retracted state to keep the blade surface smooth. Then, the driving device 30 is used to maintain a rotation speed of 50-80 RPM for rotational stirring, so as to form a large range of mortar flow and quickly mix the raw materials such as cement, sand and water in the mortar.

[0043] S2, mid-term fine mixing, when the fluidity of the mortar decreases and the viscosity increases, the stirring blade assembly 22 is retracted by half to reduce the stirring area, and its angle is adjusted to between 15-30 degrees, the angle is lowered to cope with higher resistance, and the telescopic teeth 2212 are extended by half to enhance the shearing and breaking effect of the mortar, and then the driving device 30 is used to maintain the rotation speed of 30-50RPM for rotational stirring to prevent excessive centrifugal force from affecting the uniformity of the mortar during stirring, and the shearing effect of the telescopic teeth 2212 is used to fully break up the mortar that has begun to stick together, so that all components are fully integrated; S3. In the later stage of deep mixing, when the mortar has high viscosity or contains coarse aggregate, the stirring blade assembly 22 is completely retracted to increase the torque of mixing, and its angle is adjusted to between 0-15 degrees to increase the driving force on the mortar, and the telescopic teeth 2212 are fully extended to maximize the shear force and enhance the processing of coarse aggregate and sticky mortar. Then, the driving device 30 is used to maintain a rotation speed of 15-30 RPM for rotational mixing. While avoiding equipment overload, the blades can effectively crush large-particle aggregates under the action of the telescopic teeth 2212 and make the mortar more uniform.

[0044] S4. Long-term anti-settling stirring. When the stirred mortar needs to maintain fluidity and prevent sedimentation in the mixing tank, the stirring blade assembly 22 is extended halfway, which can stir without causing too much disturbance, and its angle is adjusted to between 10-20° to ensure light stirring, and the telescopic teeth 2212 are in a retracted state. Then, the driving device 30 is used to maintain a speed of 10-20RPM for rotational stirring, which can prevent material stratification without causing excessive stirring damage.

[0045] S5. Stirring of special materials: When the mortar is fiber-reinforced mortar or mortar containing lightweight aggregates and high admixture content, the length of the stirring blade assembly 22 of the adjustable stirring mechanism 2 is fully extended to ensure sufficient stirring coverage, and its angle is adjusted to between 15-25° to avoid damage to sensitive materials such as fibers, and the telescopic teeth 2212 are extended by less than half to provide a slight shearing effect, and then the driving device 30 is used to maintain a rotation speed of 20-40 RPM for rotational stirring to ensure that the material will not be damaged during the stirring process and ensure uniform distribution; S6, automatic cleaning, pour cleaning liquid into the barrel 1, expand the length of the stirring blade assembly 22 of the adjustable stirring mechanism 2, adjust the blade angle to the maximum, and fully extend the telescopic teeth 2212, and then use the driving device 30 to maintain a speed of 50-70RPM for rotation and stirring, and the blades rotate automatically to clean the entire equipment.
