Description

Technical Field

[0001] This application relates to the field of building construction technology, and more specifically, to an energy-saving mortar mixing device for the construction of ancient buildings. Background Technology

[0002] When restoring ancient buildings, mortar is typically used. Mortar is mainly composed of lime, fine sand, and cement mixed with water. The mixing of lime and water generates heat, and the mixing effect directly affects the quality of the building materials and the smoothness of subsequent construction. There are various types of mortar mixers available, including double-layer and single-layer mixers. They usually use motor-driven mixing blades to mix the materials. Double-layer mixers store the mixture in the lower layer after mixing in the upper layer for later use. Both the upper and lower layers have mixing structures to prevent mortar sedimentation in the lower layer. The mixing structures are started simultaneously by the motor. The consistency of the mortar is generally used to judge whether the mixing is adequate, but this cannot be accurately determined manually. Long mixing times result in high energy consumption, while short mixing times lead to inadequate mixing. Furthermore, in the initial mixing stage, the materials accumulate, causing high mixing resistance and making the mixer motor prone to overheating, resulting in high energy consumption. After the mortar is mixed in the upper layer and then introduced into the lower layer, the motor continues to drive the lower layer mixing structure to prevent the lower layer mortar from settling. However, since there is no material to be mixed in the upper layer, the upper layer mixing structure runs idle, resulting in energy waste.

[0003] The structure of the product can be referenced from the double-layer mixer disclosed in Chinese Patent Document Publication No. CN207105257U.

[0004] Therefore, an energy-saving mortar mixing device for ancient building construction is needed to solve the above problems. Summary of the Invention

[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] To address the technical problems mentioned in the background section, some embodiments of this application provide an energy-saving mortar mixing device for ancient building construction, comprising: a body, including an upper tank and a lower tank; a motor, fixedly mounted on the body; a drive shaft, poweredly connected to the motor, with one end extending into the lower tank; a mixing rod, fixed on the drive shaft and located inside the lower tank; a rotating cylinder, rotatably disposed inside the upper tank and sleeved on the outside of the drive shaft; a first mounting platform and a second mounting platform, vertically distributed on the rotating cylinder; both the first and second mounting platforms have annular grooves; a first mounting ring, rotatably mounted in the annular groove on the first mounting platform and rotatably engaged with the first mounting platform; a second mounting ring, rotatably mounted in the annular groove on the second mounting platform and rotatably engaged with the second mounting platform; a first mixing blade, having a first hinge portion, through which the first mounting ring is hinged to the first mounting ring; and a second mixing blade. A second hinge portion is provided on the first stirring blade, and a second mounting ring is hinged to the second mounting ring through the second hinge portion; wherein, the first stirring blade and the second stirring blade are distributed vertically; a connecting rod is hingedly installed between the first stirring blade and the second stirring blade, so that when the first stirring blade deflects around the first hinge portion, the second stirring blade deflects around the second hinge portion synchronously; an adjustment component is provided between the rotating cylinder and the first mounting ring for adjusting the deflection angle of the first stirring blade and the second stirring blade, thereby adjusting the stirring range; the adjustment component includes: a first mounting groove is opened in the first mounting ring, a first extension rod with one end extending out of the first mounting groove is slidably connected in the first mounting groove, a compression spring is connected between the first extension rod and the end wall of the first mounting groove, a first hinge joint is provided on the first stirring blade, and one end of the first extension rod is hinged to the first hinge joint, so that when the first extension rod extends out of the first mounting groove, the first stirring blade is driven to deflect around the first hinge portion through the first hinge joint.

[0007] By using the deflected first and second stirring blades, when the mixed material accumulates in the initial stage of mixing, in order to avoid the motor heating up and energy consumption increasing due to excessive mixing resistance, the mixing range of the first and second stirring blades is small. As the mortar resistance within the mixing range gradually decreases, the mixing range is gradually increased by the deflection of the first and second stirring blades until the entire range is mixed.

[0008] Furthermore, both the first and second mounting rings are provided with arc-shaped grooves, and sliding blocks are slidably connected in the arc-shaped grooves. An abutment spring is provided between the sliding block and the side wall of the arc-shaped groove. Protective boxes are fixedly connected to both the first and second mounting platforms. A bolt rod is threaded into the protective box. One end of the bolt rod is rotatably connected to an abutment block embedded in the arc-shaped groove. The abutment block abuts against the sliding block. The abutment plane between the abutment block and the sliding block is set as an inclined surface, so that when the bolt rod is rotated to drive the abutment block to move downward, it will push the sliding block to move and squeeze the abutment spring.

[0009] By setting a bolt rod and an abutment block, when different proportions of mortar need to be mixed, the viscosity after mixing will also be different due to the different proportions. By rotating the bolt rod, the abutment block moves, which in turn pushes the sliding block and squeezes the abutment spring, thereby controlling the degree of compression of the abutment spring. When the required mortar viscosity is higher, the degree of compression of the abutment spring is also greater, and vice versa. The first mounting ring and the second mounting ring have limiting structures, which allow the first mounting ring, the second mounting ring and the rotating cylinder to rotate relative to each other within a certain angle range.

[0010] Furthermore, a first through groove is provided on the side wall of the rotating cylinder, and a mounting frame located on one side of the first through groove is fixedly connected to the rotating cylinder. A first limiting block is slidably arranged in the mounting frame, and a return spring is connected between the first limiting block and the mounting frame. A first limiting rod with one end passing through the first through groove is fixedly connected to the first extension rod. The first limiting rod has first limiting grooves evenly distributed along the axis. The first limiting block is embedded in the first limiting groove to limit the movement of the first extension rod. The part of the first limiting block embedded in the first limiting groove has an inclined surface, so that the movement of the first extension rod away from the axis of the rotating cylinder is limited, but the movement of the first extension rod closer to the axis of the rotating cylinder is not limited.

[0011] With the first limiting rod in place, after the mortar in the mixing range is mixed, the resistance of the first mixing blade and the second mixing blade is reduced, so that the first limiting block is disengaged from the first limiting groove under the action of the abutment spring. At this time, under the action of the compression spring, the first extension rod extends away from the axis of the rotating cylinder, so that the first mixing blade and the second mixing blade deflect to a larger mixing range.

[0012] Furthermore, a gas chamber is provided inside the second mounting platform, which is filled with expanding gas. A pneumatic cylinder is fixedly installed inside the rotating cylinder and is connected to the gas chamber. The pneumatic cylinder has a piston. The expansion of the gas in the gas chamber pushes the piston to move. A guide bar is fixedly connected to the piston of the pneumatic cylinder. A sliding ring with a sliding fit is sleeved on the first limiting rod. One end of the first limiting rod has a limiting edge to prevent the sliding ring from slipping out. A connecting spring is provided between the sliding ring and the limiting edge. The guide bar abuts against the sliding ring. When the pneumatic cylinder drives the guide bar to move upward, it drives the first extension rod to move in the direction of the axis of the rotating cylinder through the sliding ring.

[0013] With the gas chamber and pneumatic cylinder in place, when the mixture is in the upper tank, the lime and water in the mixture react to generate heat, causing the gas in the gas chamber to expand. This causes the piston of the pneumatic cylinder to push the guide bar to move. The guide bar contacts the sliding ring, pushing the first extension rod to move in the circumferential direction of the rotating cylinder, which can adjust the first and second stirring blades to the minimum stirring range.

[0014] Furthermore, a second mounting groove is provided inside the second mounting ring, and a second extension rod with one end extending out of the second mounting groove is slidably connected inside the second mounting groove. A second hinge joint is provided on the second stirring blade, and one end of the second extension rod is hinged to the second hinge joint, so that when the second stirring blade deflects, the second extension rod is driven to move and extend away from the axis of the rotating cylinder through the second hinge joint. A second limiting rod is provided on the second extension rod, and the second limiting rod is slidably engaged with the second extension rod. A second through groove is provided on the side wall of the rotating cylinder, and the second limiting rod extends into the rotating cylinder through the second through groove. A second limiting block located on one side of the second through groove is fixedly connected to the rotating cylinder, and a second limiting groove is provided on the second limiting rod for the second limiting block to be embedded in.

[0015] When the second stirring blade deflects, the second extension rod will move.

[0016] Furthermore, a retaining ring is fixedly connected to one end of the second limiting rod, and a contact spring is sleeved on the second limiting rod. One end of the contact spring is fixed to the retaining ring. When the second extending rod moves away from the axis of the rotating cylinder, it will squeeze the contact spring. An anti-detachment spring is connected between one end of the second limiting rod and the side wall of the second mounting groove.

[0017] With the anti-detachment spring in place, when the second stirring blade has not reached its maximum stirring range, the embedded block is engaged in the limiting groove of the fixed wheel under the action of the anti-detachment spring, and the rotating cylinder rotates synchronously with the drive shaft. When the second stirring blade reaches its maximum stirring range, it stirs all the mortar in the upper tank. At this time, the stirring is not yet complete. The resistance experienced by the first and second stirring blades will compress the abutment spring. At this time, the second limiting block is engaged in the second limiting groove, and the second extension rod abuts against the contact spring, causing the contact spring to compress. Under the action of the second limiting block, the embedded block will not detach from the limiting groove of the fixed wheel until all the mortar in the upper tank is stirred. The resistance experienced by the second and first stirring blades decreases. At this time, under the action of the abutment spring, the second limiting block disengages from the second limiting groove, and under the action of the contact spring, the embedded block disengages from the tooth groove of the fixed wheel. The rotating cylinder no longer rotates synchronously with the drive shaft, thus avoiding continuous stirring after the mortar is stirred, which would cause energy waste.

[0018] Furthermore, a fixed wheel is fixedly connected to the drive shaft, and a limiting groove is distributed circumferentially on the fixed wheel. An embedded block embedded in the limiting groove is fixedly connected to one end of the second limiting rod.

[0019] Furthermore, the upper tank is equipped with a feeding port, and a channel is opened at the lower end of the upper tank. The mixed mortar falls into the lower tank through the channel. A sealing plate is slidably installed at the lower end of the upper tank to close the channel, and a discharge port is provided at the lower end of the lower tank.

[0020] The beneficial effects of this application are as follows: 1. By setting the first and second stirring blades to deflect, when the mixed material accumulates in the initial stage of mixing, in order to avoid the motor heating up and energy consumption due to excessive mixing resistance, the mixing range of the first and second stirring blades is small. As the mortar resistance in the mixing range gradually decreases, the mixing range is gradually increased by deflecting the first and second stirring blades until the entire range is mixed.

[0021] 2. By setting bolt rods and abutment blocks, when different proportions of mortar need to be mixed, the viscosity after mixing will also be different due to the different proportions. By rotating bolt rods, the abutment blocks move, which in turn pushes the sliding block and squeezes the abutment spring, thereby controlling the degree of compression of the abutment spring. When the required mortar viscosity is higher, the degree of compression of the abutment spring is also greater, and vice versa. There are limiting structures on the first mounting ring and the second mounting ring, so that the first mounting ring, the second mounting ring and the rotating cylinder can rotate relative to each other within a certain angle range.

[0022] 3. Through the set gas chamber and pneumatic cylinder, when the mixture is in the upper tank, the lime and water in the mixture react to generate heat, causing the gas in the gas chamber to expand, which in turn causes the piston of the pneumatic cylinder to push the guide bar to move. The guide bar contacts the sliding ring, pushing the first extension rod to move in the circumferential direction of the rotating cylinder, which can adjust the first stirring blade and the second stirring blade to the minimum stirring range.

[0032] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] Reference Figure 1-10 An energy-saving mortar mixing device for ancient building construction includes: a body 10, a motor 13, a drive shaft 15, a mixing rod 16, a rotating cylinder 17, a first mounting platform 18, a second mounting platform 19, a first mounting ring 20, a second mounting ring 21, a first mixing blade 22, a second mixing blade 23, and a connecting rod 24. The machine body 10 includes an upper tank 11 and a lower tank 12. The mortar mixture is first stirred in the upper tank 11. After stirring, the mortar enters the lower tank 12 for use. This can be referred to as a double-layer mixer in the prior art. Specifically, the upper tank 11 is provided with a feeding port 14. Lime, fine sand, cement, etc. are fed into the upper tank 11 through the feeding port 14. A channel 62 is opened at the lower end of the upper tank 11. The stirred mortar falls into the lower tank 12 through the channel 62. A sealing plate 61 is slidably provided at the lower end of the upper tank 11 to close the channel 62. A discharge port 59 is provided at the lower end of the lower tank 12. The stirred mortar can be passed into the lower tank 12 by pulling out the embedded block 56. The discharge port 59 at the lower end of the lower tank 12 is used to take out the mortar. A motor 13 is fixedly installed on the machine body 10. A drive shaft 15 is fixedly installed at the power output end of the motor 13, with one end passing through the upper tank 11 and extending into the lower tank 12. A stirring rod 16 located in the lower tank 12 is fixedly connected to the drive shaft 15. The drive shaft 15 drives the stirring rod 16 to stir the mortar in the lower tank 12 to prevent sedimentation. A rotating cylinder 17 is rotatably connected inside the upper tank 11, sleeved on the outside of the drive shaft 15. Both the upper and lower ends of the rotating cylinder 17 are sealed to the inner wall of the upper tank 11, preventing mortar from entering the rotating cylinder 17.

[0034] In the initial stage of mixing, the accumulation of materials leads to greater mixing resistance, which can easily cause the motor 13 to overheat and increase energy consumption. Therefore, a first mounting platform 18 and a second mounting platform 19 are arranged vertically on the rotating drum 17. Both the first mounting platform 18 and the second mounting platform 19 have annular grooves. A first mounting ring 20 is rotatably mounted in the annular groove of the first mounting platform 18, and the first mounting ring 20 rotatably engages with the first mounting platform 18, creating a rotational seal between the first mounting ring 20 and the mounting groove, preventing mortar from entering the gap between the first mounting ring 20 and the first mounting platform 18. A second mounting ring 21 is rotatably mounted in the annular groove of the second mounting platform 19, and the second mounting ring 21 rotatably engages with the second mounting platform 19, creating a rotational seal between the second mounting ring 21 and the mounting groove, preventing mortar from entering the gap between the second mounting ring 21 and the second mounting platform 19. Two first stirring blades 22 are provided on the first mounting ring 20, and the first stirring blades 22 are hinged to the first mounting ring 20 via a first hinge part 27. Two second stirring blades 23 are provided on the second mounting ring 21, and the second stirring blades 23 are hinged to the second mounting ring 21 via a second hinge joint 52. The first stirring blade 22 and the second stirring blade 23 are arranged vertically, and a connecting rod 24 is hinged between the vertically distributed first stirring blade 22 and second stirring blade 23, so that the first stirring blade 22 and the second stirring blade 23 deflect synchronously. Limiting protrusions are provided on the first mounting ring 20 and the second mounting ring 21, so that the first mounting ring 20, the second mounting ring 21 and the rotating cylinder 17 can rotate relative to each other at a certain angle.

[0035] Specifically, the first stirring blade 22 and the second stirring blade 23 have two extreme positions. At the first extreme position, the stirring range of the first stirring blade 22 and the second stirring blade 23 is the smallest; at the second extreme position, the stirring range of the first stirring blade 22 and the second stirring blade 23 is the largest. When the mixed material accumulates in the initial stage of stirring, the first stirring blade 22 and the second stirring blade 23 are in the smallest stirring range to reduce stirring resistance. After the mixing of the components within the stirring range is completed, the stirring range is gradually increased by the deflection of the first stirring blade 22 and the second stirring blade 23 until all the mixed material in the upper tank 11 is mixed.

[0036] To gradually increase the mixing range of the first stirring blade 22 and the second stirring blade 23, a first mounting groove 54 is provided in the first mounting ring 20. A first extension rod 25, one end of which protrudes from the first mounting groove 54, is slidably connected within the first mounting groove 54. A compression spring 58 is connected between the first extension rod 25 and the end wall of the first mounting groove 54, with both ends of the compression spring 58 fixedly connected to the first extension rod 25 and the end wall of the first mounting groove 54, respectively. A first hinge joint 26 is provided on the first stirring blade 22, and one end of the first extension rod 25 is hinged to the first hinge joint 26. Specifically, when the first extension rod 25 extends out of the first mounting groove 54 (i.e., moves away from the axis of the rotating cylinder 17), the first hinge joint 26 causes the first stirring blade 22 to deflect around the first hinge portion 27, thereby gradually increasing the mixing range.

[0037] Since the mixing resistance decreases after the mortar is evenly mixed, it is necessary to gradually increase the mixing area after mixing the mortar in a certain area. Arc-shaped grooves 33 are provided on both the first mounting ring 20 and the second mounting ring 21. Sliding blocks 34 are slidably connected within the arc-shaped grooves 33. A retaining spring 35 is provided between the sliding block 34 and the side wall of the arc-shaped groove 33. Protective boxes 37 are fixedly connected to both the first mounting platform 18 and the second mounting platform 19. Bolt rods 38 are threaded into the protective boxes 37, and one end of the bolt rod 38 is rotatably connected to an embedded... The abutment block 36 is located within the arc-shaped groove 33. The abutment block 36 abuts against the sliding block 34, and the contact surface between the abutment block 36 and the sliding block 34 is inclined. When the rotating bolt rod 38 moves the abutment block 36 downwards, it pushes the sliding block 34 and compresses the abutment spring 35. The protective box 37 has an openable lid to prevent mortar from entering and affecting the bolt rod 38. The compression degree of the abutment spring 35 can be adjusted by controlling the screw-in length of the bolt rod 38; the specific screw-in length can be determined experimentally. When the first stirring blade 22 and the second stirring blade 23 encounter resistance during stirring, they compress the abutment spring 35. A first through groove 45 is provided on the side wall of the rotating cylinder 17. A mounting frame 30 located on one side of the first through groove 45 is fixedly connected to the rotating cylinder 17. A first limiting block 31 is slidably disposed in the mounting frame 30. A return spring 32 is connected between the first limiting block 31 and the mounting frame 30. The two ends of the return spring 32 are fixedly connected to the first limiting block 31 and the mounting frame 30, respectively. A first extending rod 25 is fixedly connected to a first limiting rod 28 with one end passing through the first through groove 45. First limiting grooves 29 are evenly distributed along the axis on the first limiting rod 28. The first limiting block 31 is embedded in the first limiting groove 29 to limit the movement of the first extending rod 25. The part of the first limiting block 31 embedded in the first limiting groove 29 has an inclined surface, which limits the movement of the first extending rod 25 away from the axis of the rotating cylinder 17, but does not limit the movement of the first extending rod 25 towards the axis of the rotating cylinder 17.

[0038] Specifically, after the first stirring blade 22 and the second stirring blade 23 have finished mixing the mortar in the area, due to the reduced resistance, the first limiting block 31 disengages from the first limiting groove 29 under the action of the abutment spring 35. At this time, the first limiting rod 28 can move, and under the action of the compression spring 58, the first extending rod 25 extends away from the axis of the rotating cylinder 17, thereby causing the first stirring blade 22 to deflect and drive the second stirring blade 23 to deflect, thus increasing the mixing range. When the mixing range increases, due to the accumulation of mixed material, the resistance increases again, thus continuing to compress the abutment spring 35, causing the first limiting block 31 to re-embed into one of the first limiting grooves 29, completing one adjustment of the mixing range. This allows the mixing range to be increased to continue mixing after the mixed material in the mixing range has been finished.

[0039] To ensure that the first stirring blade 22 and the second stirring blade 23 return to their first extreme positions when mixing materials are added to the upper tank 11, a gas chamber 39 is provided in the second mounting platform 19. The gas chamber 39 is filled with expanding gas. A pneumatic cylinder 40 is fixedly installed in the rotating cylinder 17 and is connected to the gas chamber 39. The pneumatic cylinder 40 has a piston. The expansion of the gas in the gas chamber 39 pushes the piston to move. A guide bar 41 is fixedly connected to the piston of the pneumatic cylinder 40. A sliding ring 42 is fitted on the first limiting rod 28. One end of the first limiting rod 28 has a limiting edge 44 to prevent the sliding ring 42 from slipping. A connecting spring 43 is connected between the sliding ring 42 and the limiting edge 44. The two ends of the connecting spring 43 are fixedly connected to the sliding ring 42 and the limiting edge 44, respectively. The guide bar 41 abuts against the sliding ring 42. When the pneumatic cylinder 40 drives the guide bar 41 to move upward, it drives the first extension rod 25 to move in the direction of the axis of the rotating cylinder 17 through the sliding ring 42. When the mixture is in the upper tank 11, the lime in the mixture reacts with water to generate heat, causing the gas in the gas chamber 39 to expand. This causes the piston of the pneumatic cylinder 40 to push the guide bar 41 to move. The guide bar 41 contacts the sliding ring 42, pushing the first extension rod 25 to move in the circumferential direction of the rotating cylinder 17, so that the first stirring blade 22 and the second stirring blade 23 return to the first limit position. The gas in the gas chamber 39 is a heated and expanding gas, which can be nitrogen.

[0040] To prevent further mixing or idling and energy consumption after the mortar in the upper tank 11 has been mixed, a second mounting groove 55 is provided in the second mounting ring 21. A second extension rod 47 with one end extending out of the second mounting groove 55 is slidably connected in the second mounting groove 55. A second hinge joint 52 is provided on the second mixing blade 23. One end of the second extension rod 47 is hinged to the second hinge joint 52, so that when the second mixing blade 23 deflects, the second extension rod 47 is driven to move away from the axis of the rotating cylinder 17 through the second hinge joint 52. A second limiting rod 48 is provided on the second extension rod 47 and slides through the second extension rod 47. A second through groove 49 is provided on the side wall of the rotating cylinder 17. The second limiting rod 48 extends into the rotating cylinder 17 through the second through groove 49. A second limiting block 50 located on one side of the second through groove 49 is fixedly connected to the rotating cylinder 17. A second limiting groove 57 is provided on the second limiting rod 48 for the second limiting block 50 to be embedded. A retaining ring is fixedly connected to one end of the second limiting rod 48. A contact spring 51 is sleeved on the second limiting rod 48, with one end of the contact spring 51 fixed to the retaining ring. When the second extending rod 47 moves away from the axis of the rotating cylinder 17, it will compress the contact spring 51. An anti-detachment spring 60 is connected between one end of the second limiting rod 48 and the side wall of the second mounting groove 55. The two ends of the anti-detachment spring 60 are fixedly connected to the second limiting rod 48 and the side wall of the second mounting groove 55, respectively. A fixed wheel 46 is fixedly connected to the drive shaft 15. The fixed wheel 46 has circumferentially distributed limiting grooves. An embedded block 56 embedded in the limiting groove is fixedly connected to one end of the second limiting rod 48.

[0041] Specifically, when the first stirring blade 22 and the second stirring blade 23 are in the second extreme position, the second extension rod 47 will abut against one end of the contact spring 51 and squeeze the contact spring 51. At this time, due to the action of the second limiting block 50, the second limiting rod 48 does not move until all the mortar in the upper tank 11 is stirred. Under the action of the abutment spring 35, the second limiting block 50 is disengaged from the second limiting groove 57, and then the embedded block 56 is disengaged from the limiting groove of the fixed wheel 46, so that the rotating cylinder 17 no longer rotates with the drive shaft 15, avoiding the need to continue stirring or idle after stirring is completed, thus consuming energy.

[0042] Working or installation process: Adjust the screw length of the bolt rod 38 according to the mortar ratio, thereby adjusting the compression degree of the abutment spring 35, so that when the first stirring blade 22 and the second stirring blade 23 are in the second limit position and the mortar in the upper tank 11 is stirred, the first mounting ring 20 can cause the second limiting block 50 to disengage from the second limiting groove 57 and the first limiting block 31 to disengage from the first limiting groove 29 under the action of the abutment spring 35. In the initial state, the first stirring blade 22 and the second stirring blade 23 are in the second limit position; 1. A mixture of lime, fine sand, and cement is fed into the upper tank 11 through the feeding port 14. Water is then added to the upper tank 11. The lime in the mixture reacts with the water, generating heat and causing the gas in the gas chamber 39 to expand. This expands the piston, causing the guide bar 41 to move. The guide bar 41 abuts against the sliding ring 42 and moves the first limiting rod 28 towards the axis of the rotating cylinder 17. Because the first limiting block 31 has an inclined surface, it does not limit the first limiting rod 28 at this time. Simultaneously, it moves the first extending rod 25, causing the first stirring blade 22 to... The second stirring blade 23 returns to the first limit position. When the second stirring blade 23 returns to the first limit position, the anti-detachment spring 60 causes the embedded block 56 to be embedded into the limiting groove of the fixed wheel 46, and then the motor 13 is started to output power. It should be noted that when the first extension rod 25 moves towards the axis of the rotating cylinder 17, it will compress the compression spring 58. When the temperature in the upper tank 11 drops, the second mounting ring 21 returns to the initial state. At this time, under the action of the connecting spring 43, it will not push the first limiting rod 28, nor will it hinder the movement of the guide bar 41. 2. The motor 13 drives the drive shaft 15 to rotate, which in turn drives the rotating cylinder 17 to rotate under the action of the fixed wheel 46. This causes the first stirring blade 22 and the second stirring blade 23 to rotate. Since the first stirring blade 22 and the second stirring blade 23 are at their first extreme positions at this time, the stirring range is minimal, and therefore the resistance they experience is also small, thus avoiding heat generation and energy consumption by the motor. At the same time, the resistance experienced by the first stirring blade 22 and the second stirring blade 23 will compress and press against the spring 35, causing the first limiting block 31 to embed into the first limiting groove 29 and the second limiting block 50 to embed into the second limiting groove 57. Inside, after the first stirring blade 22 and the second stirring blade 23 have finished stirring the mortar within the stirring range, the resistance experienced by the first stirring blade 22 and the second stirring blade 23 decreases. At this time, under the action of the abutment spring 35, the first limiting block 31 disengages from the first limiting groove 29, and the second limiting block 50 disengages from the second limiting groove 57. Under the action of the compression spring 58, the first extending rod 25 extends, causing the first stirring blade 22 and the second stirring blade 23 to deflect, increasing the stirring range and the resistance. At this time, the abutment spring 35 is recompressed, and the above operation is repeated.

[0043] 3. When the first stirring blade 22 and the second stirring blade 23 gradually deflect to their second extreme positions, the second extending rod 47 abuts against and squeezes the contact spring 51. After all the materials in the upper tank 11 have been mixed, the second limiting block 50 disengages from the second limiting groove 57 again under the action of the abutment spring 35. At this time, under the action of the contact spring 51, the embedded block 56 disengages from the limiting groove on the fixed wheel 46, and the rotating cylinder 17 no longer rotates synchronously with the drive shaft 15, avoiding continued mixing or idling and energy consumption. At this time, by removing the embedded block 56, the mortar falls into the lower tank 12 and is stirred by the stirring rod 16 to prevent sedimentation.

[0044] 4. When lime, fine sand, cement and other mixtures are added to the upper tank 11 again, the gas in the gas chamber 39 expands again, and step one is repeated for the next stirring.
