[0022] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 As shown in The horizontal stirrer 3 includes a rod body 31 rotatably arranged at the top of the stirring tank 1. A stirring motor part 33 for driving the rod body 31 to rotate is arranged on the stirring tank 1. Five groups of stirring blades 32 are symmetrically arranged on the outer circumference of the rod body 31. The stirring blades 32 are connected to the rod body 31 through an angle adjustment assembly 4; The angle adjustment assembly 4 includes a rotating part 41 rotatably arranged on the rod body 31. The rotating part 41 is connected to the rod body 31 through a sealing bearing 42. A guiding groove 412 with rifling 411 is opened at the end of the rotating part 41 near the rod body 31, and the other end is connected to the stirring blade 32; A slider 45 slides in the guiding groove 412. A limiting block 451 that slidably cooperates with the rifling 411 is arranged on the outer wall of the slider 45. A hydraulic assembly for driving the slider 45 to move only horizontally is arranged in the rod body 31; The hydraulic assembly drives the slider 45 to move radially along the rotating part 41, so that the limiting block 451 slides along the track of the rifling 411, driving the axis of the rotating part 41 to rotate, realizing multi-stage adjustment of the working angle of the stirring blade 32 and meeting the mixing requirements at each stage.

[0023] In this embodiment, during operation, after the material enters the stirring tank 1 through the feed hopper 11, the vertical stirrer 2 lifts the bottom material to the top to form a circulating flow; at the same time, the rod body 31 of the horizontal stirrer 3 rotates horizontally under the drive of the stirring motor part 33, driving multiple groups of stirring blades 32 to mix the material; during the mixing process, the hydraulic assembly drives the slider 45 to slide radially along the guiding groove 412 of the rotating part 41; the limiting block 451 on the slider 45 cooperates with the rifling 411, converting the linear motion of the slider into the rotational motion of the rotating part 41, thereby adjusting the inclination angle of the stirring blade 32; In the dry mixing stage, the blades are adjusted to a large inclination angle of 60° to enhance the dispersion of the material, form strong convective mixing, and shorten the dry mixing time; in the wet mixing stage after adding water, by detecting the sudden drop in the current value of the second motor 331, it is judged that the viscosity of the material decreases, and the blades are adjusted to an inclination angle of 45° to avoid slurry splashing; in the light aggregate adding stage, the inclination angle of 30° is locked to prevent the light aggregate from being broken; Through the collaborative design of the vertical stirrer 2 and the horizontal stirrer 3 and combined with the dynamic angle adjustment function, the mixing efficiency of the mortar is improved in this device.

[0024] Preferably, the hydraulic assembly includes an oil delivery rod 43 arranged in the rod body 31. A piston part 44 corresponding to the rotating part 41 is communicated with the oil delivery rod 43. A hydraulic pump 46 for delivering oil to the oil delivery rod 43 is arranged at the top of the stirring tank 1. The hydraulic pump 46 is communicated with the oil delivery rod 43 through an oil delivery pipe, and the top of the oil delivery pipe and the oil delivery rod 43 are connected through a rotary joint; The piston member 44 includes a first cylinder body 441 fixed to the oil delivery rod 43. The inner cavity of the first cylinder body 441 communicates with the oil delivery rod 43. A first plug 442 slides inside it. On one side of the first plug 442 away from the oil delivery rod 43, a first ejector rod 443 is fixed. The other end of the first ejector rod 443 is fixedly connected to the slider 45. A first spring 445 is connected between the slider 45 and the end of the first cylinder body 441.

[0025] In this embodiment, when the hydraulic system works, the hydraulic pump 46 injects pressurized oil into the oil delivery rod 43, and the oil pressure is synchronously transmitted to each piston member 44 through the oil delivery rod 43. When the oil enters the first cylinder body 441, the pressure drives the first plug 442 to move outward against the elastic force of the first spring 445. The first ejector rod 443 fixed to the first plug 442 then pushes the slider 45 to slide outward along the rod body 31. At this time, the limiting block 451 on the outer wall of the slider 45 slides along the rifling 411 of the rotating member 41 in a spiral trajectory, converting the linear displacement into the rotational motion of the rotating member 41, thereby driving the stirring blade 32 to rotate to a preset angle. During this process, the angle of the stirring blade 32 gradually becomes smaller. When reset is needed, the hydraulic pump 46 reduces the oil pressure, and the first spring 445 contracts to pull the first plug 442 back, driving the slider 45 to slide in the reverse direction, so that the stirring blade 32 returns to the initial angle. Multiple piston members 44 synchronously control the corresponding stirring blades 32 to achieve synchronous adjustment of the angles of multiple groups of blades.

[0026] Preferably, an angle fixing assembly 5 for fixing the use angle of the stirring blade 32 is further provided on the oil delivery rod 43. The angle fixing assembly 5 includes a second cylinder body 51 communicating with the oil delivery rod 43. A second plug 52 slides inside the second cylinder body 51. On one side of the second plug 52 away from the oil delivery rod 43, a second ejector rod 53 is fixed. The other end of the second ejector rod 53 is fixed with a fixed gear 54. A fixed gear ring 55 meshing with the fixed gear 54 is fixedly sleeved on the outer periphery of the rotating member 41. A second spring 56 is connected between the fixed gear 54 and the end of the second cylinder body 51. The second cylinder body 51, the second plug 52, and the second ejector rod 53 have the same dimensions as the first cylinder body 441, the first plug 442, and the first ejector rod 443.

[0027] After adding lightweight aggregate, the hydraulic component adjusts the mixing blade 32 to 30°, reducing the material-receiving area of the blade to avoid crushing of the lightweight aggregate. During this process, since the first cylinder 441 and the second cylinder 51 share the same oil delivery rod 43, the oil can enter the second cylinder 51 of the angle-fixing component 5 synchronously, pushing the second plug 52 to move outward against the elastic force of the second spring 56, so that the fixed gear 54 at the end of the second ejector rod 53 meshes with the fixed tooth ring 55 of the rotating part 41. At this time, the tooth surfaces of the fixed gear 54 and the fixed tooth ring 55 engage to form mechanical self-locking, preventing the rotating part 41 from shifting, locking the angle of the mixing blade 32 at 30°, and avoiding crushing of the lightweight aggregate due to an increase in the angle of the mixing blade 32. When the angle needs to be adjusted again, the hydraulic pump 46 reduces the oil pressure, the second spring 56 rebounds to pull the second plug 52 back to its original position, the fixed gear 54 disengages from the fixed tooth ring 55, and the rotation restriction on the rotating part 41 is released. Since the second cylinder 51 and the first cylinder 441 adopt a synchronous size design, their oil pressure response characteristics are perfectly matched with the piston part 44, ensuring the timing consistency of the angle adjustment and locking actions.

[0028] Preferably, the mixing motor part 33 includes a second motor 331 fixed to the outer periphery of the mixing tank 1. The top of the output rod of the second motor 331 is fixed with a driving sprocket 332. A driven sprocket 333 is fixed to the outer periphery of the rod body 31 located above the mixing tank 1. A transmission chain 334 for transmission is sleeved between the driving sprocket 332 and the driven sprocket 333. When the mixing motor part 33 is started, the second motor 331 drives the driving sprocket 332 at the top of the output rod to rotate, drives the driven sprocket 333 at the upper end of the rod body 31 to rotate synchronously through the transmission chain 334, thereby driving the rod body 31 of the horizontal mixer 3 to rotate around the axis, and driving multiple groups of mixing blades 32 to mix the materials in the mixing tank 1. In addition, during the wet mixing stage after adding water, the viscosity of the material decreases. At this time, the power required for the second motor 331 to drive the rod body 31 to rotate will drop suddenly. Therefore, the external control system judges that the viscosity of the material has decreased by detecting the sudden drop in the current value of the second motor 331, and then sends a working signal to the hydraulic component to adjust the angle of the mixing blade 32, realizing the automatic adjustment of the angle of the mixing blade 32. At the same time, a multispectral sensor can be added to the feed hopper 11 to identify the feeding state component of the lightweight aggregate to judge whether the lightweight aggregate is fed. When the sensor detects that the lightweight aggregate is fed, it sends a signal to the external control system, and the external control system sends working signals to the hydraulic component and the angle-fixing component 5 to lock the angle of the mixing blade 32 at 30°, further realizing the automatic adjustment of the angle of the mixing blade 32.

[0029] Preferably, the vertical stirrer 2 includes an auger rod 21 rotatably arranged at the top of the inner cavity of the mixing tank 1. A first motor 24 for driving the auger rod 21 to rotate is arranged at the top of the mixing tank 1. An outer periphery of the auger rod 21 is sleeved with a feeding cylinder 22 fixed to the bottom of the inner cavity of the mixing tank 1. The inner diameter of the feeding cylinder 22 is adapted to the auger blades on the auger rod 21 and is the same as the inner diameter of the discharge pipe 12. At least one group of through holes 23 are formed in the outer periphery of the bottom of the feeding cylinder 22, and the top of the feeding cylinder 22 is arranged at an interval from the top of the mixing tank 1; The lower end of the auger rod 21 extends into the feeding cylinder 22; When the vertical stirrer 2 is started, the first motor 24 drives the auger rod 21 to rotate in the feeding cylinder 22. The materials at the bottom of the mixing tank 1 are continuously lifted to the top of the feeding cylinder 22 by the auger blades, and are scattered and fall back to the bottom of the tank from the space between the top and the mixing tank 1 under the action of centrifugal force, forming a vertical cycle; when the materials reach the preset mixing degree, the first motor 24 drives the auger rod 21 to rotate in reverse, switches to the discharging mode, and smoothly guides the materials into the discharge pipe 12 through the through holes 23 at the bottom of the feeding cylinder 22 for stable discharging outwards.

[0030] Preferably, a cooling sandwich layer 13 is arranged on the side wall of the mixing tank 1, which is communicated with an external circulating water supply device to realize internal water flow circulation; When the temperature of the materials rises due to friction or chemical reaction during the mixing process, the external circulating water supply device is started. The cooling water is injected into the cooling sandwich layer 13 on the side wall of the mixing tank 1 through the water inlet 131. The water flow circulates in the sandwich layer, absorbing the heat inside the tank; the heated cooling water returns to the heat exchanger in the external heat dissipation device through the water outlet 132 for cooling treatment, forming a closed-loop cooling cycle.

[0031] During use, after the material is put into the mixing box 1 through the feed hopper 11, the auger rod 21 of the vertical agitator 2 rotates under the drive of the first motor 24, and the bottom material is lifted along the feed cylinder 22 to the top of the mixing box 1 and thrown down, forming an axial circulation flow; at the same time, the rod body 31 of the horizontal agitator 3 is driven to rotate by the second motor 331, driving multiple groups of stirring blades 32 to rotate and mix the materials; during the mixing process, the hydraulic pump 46 injects pressurized oil into the oil delivery rod 43 in the rod body 31, driving the slider 45 to slide radially along the guide groove 412 of the rotating part 41, and the limit block 451 on the slider 45 cooperates with the rifling 411 to convert the linear motion into rotation The inclination angle of the blades is adjusted dynamically by rotating motion; when the material is dry mixed, the stirring blades 32 are adjusted to maintain a large inclination angle to enhance material dispersion; in the wet mixing stage, the hydraulic system is triggered to reduce the inclination angle of the stirring blades 32 by detecting the change in the current value of the second motor 331 to avoid slurry splashing. When light aggregate is added, the multi-spectral sensor identifies the material characteristics and links the angle fixing component 5 to engage the fixed gear 54 with the fixed gear ring 55 to lock the stirring blades 32 to an anti-crushing angle; after mixing is completed, the auger rod 21 reverses to guide the material into the discharge pipe 12 through the bottom through hole 23 of the feed barrel 22. During this period, the circulating water flow in the cooling interlayer 13 continuously absorbs the stirring heat to maintain the material temperature stable.
