Description

Technical Field

[0001] The present invention relates to the technical field of mixer trucks, and specifically to a self-loading mixer truck with an automatic water content detection function. Background Art

[0002] The technology of concrete mixer trucks continues to develop towards modularization, intelligence, and high efficiency and energy conservation. Modern equipment has gradually integrated functions such as automatic weighing, temperature control adjustment, and Internet of Things monitoring. In the feeding link, the technology of aggregate bin storage and powder moisture-proof has become a research hotspot; the mixing mechanism focuses on eliminating mixing dead corners and improving uniformity; the discharging system focuses on optimizing the anti-blocking structure and residual control. The industry development trend shows that through multi-dimensional composite mixing, closed-loop temperature control, and intelligent proportioning and other technical means, the quality of concrete and the energy efficiency of equipment can be further improved.

[0003] Traditional mixer trucks mostly use a single screw conveyor to supply aggregate and powder. The aggregate intermediate bin lacks a physical separation structure, which easily leads to particle size mixing. The mixing mechanism generally relies on a single rotating blade for mixing, and it is difficult to eliminate the stratification phenomenon caused by density differences. The discharging system mostly uses a straight-through channel with simple stirring, resulting in insufficient secondary mixing of materials and more residues. The detection mechanism often uses a fixed sensor, which cannot adapt to the dynamic changes of the material liquid level, resulting in deviation of monitoring data.

[0004] In the prior art, the powder conveying system lacks a closed-loop temperature control design and cannot effectively adjust the temperature of the powder, easily resulting in caking or a decrease in fluidity; the aggregate proportioning relies on manual adjustment of valves, with large errors and difficult to achieve dynamic compensation. The single rotating mode of the mixing mechanism cannot completely solve the problem of material stratification, and the mixing uniformity is limited. The discharging system has a simple structure and lacks a turbulence generating and dynamic cleaning device, resulting in poor discharging uniformity and a high residual amount, and frequent shutdowns are required for cleaning. The probe of the detection mechanism is fixedly installed and is easily buried by materials or separated from contact, affecting the continuity of monitoring. Therefore, those skilled in the art have provided a self-loading mixer truck with an automatic water content detection function to solve the problems raised in the above background. Summary of the Invention

[0005] The purpose of the present invention is to provide a self-loading mixer truck with an automatic water content detection function to solve the problems raised in the prior art.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] The mixer truck includes a feeding mechanism, a detection mechanism, a mixing mechanism, a mixing truck, and a discharging mechanism. The feeding mechanism is connected to the mixing mechanism, the detection mechanism is firmly connected to the mixing mechanism, the mixing truck abuts against the discharging mechanism, the detection mechanism is connected to the mixing mechanism, the detection mechanism is connected to the discharging mechanism, and the discharging mechanism is connected to the mixing truck.

[0008] By adopting the above technical solution, the powder bin of the feeding mechanism realizes quantitative powder conveying through the cooperation of a screw conveyor and an electromagnetic valve. The spirally wound water pipe maintains an appropriate temperature for the powder under the control of a heating box and a cooling box. The water pump forms a closed-loop water path through a circulation valve; the partition plate in the aggregate intermediate bin separates and stores aggregates of different particle sizes. The conveyor belt and the auger conveyor respectively convey massive and powdery aggregates, and a control motor drives a control valve to achieve proportioning; the amplitude motor of the stirring mechanism drives a sliding block to move up and down through an amplitude screw rod, so that the articulated slider drives a rotating disk to generate axial vibration through an articulated rod. At the same time, the stirring motor drives the stirring rod to rotate radially, forming a compound stirring mode. The conductivity probe of the detection mechanism forms a dynamic suspension structure with an electromagnetic block through a first elastic member. The magnetic repulsion force makes the magnetic block drive the probe to fit the inner wall of the stirring tank in real time, monitor the change in the conductivity of the material and feedback it to the discharge valve; the spiral spoiler in the discharge cylinder guides the material to swirl through an inclined surface, and the arc surface reduces resistance. The scraping brush of the rotating stirring rod scrapes the residue on the cylinder wall, and finally realizes the discharge uniformity.

[0009] Further, the feeding mechanism includes a powder component, an aggregate component, an aggregate intermediate bin, and a general feeding frame. The powder component, the aggregate component, and the aggregate intermediate bin are evenly and firmly connected to the general feeding frame. The aggregate component and the aggregate intermediate bin are connected, and both the powder component and the aggregate component are connected to the stirring mechanism. The aggregate intermediate bin is provided with a partition plate for separating different aggregates stored in the aggregate intermediate bin.

[0010] By adopting the above technical solution, the general feeding frame adopts a frame structure to integrally assemble the powder component, the aggregate component, and the aggregate intermediate bin. The powder bin completes continuous and controllable powder conveying through the linkage of a screw conveyor and an electromagnetic valve. The spirally wound water pipe cooperates with the heating box and the cooling box to adjust the powder temperature; the corrugated partition plate arranged inside the aggregate intermediate bin divides it into independent compartments, which can store aggregates of different particle sizes at the same time and avoid mixing; the conveyor belt and the auger conveyor of the aggregate component respectively correspond to the directional transmission of massive and powdery aggregates. The control motor realizes the proportioning control of multi-category aggregates by adjusting the opening amplitude of the control valve; the whole system makes the powder conveying pipeline and the aggregate conveying channel be arranged in layers in the general feeding frame through modular design, which not only ensures that the material conveying paths do not interfere with each other, but also facilitates later maintenance and repair.

[0011] Further, the powder component includes a powder bin, a water pipe, a heating box, a cooling box, a screw conveyor, an electromagnetic valve, a water pump, a water outlet valve, a conveying pipe, a circulation valve, and a powder rack.

[0012] By adopting the above technical solutions, the powder bin is fixedly supported by the powder rack, and the spiral conveyor cooperates with the electromagnetic valve to achieve quantitative conveying of powder from the bin to the mixing mechanism; the spirally wound water pipe adjusts the circulating water temperature through the heating box and the cooling box, and the water pump drives the water flow through the circulation valve to form a reversible circuit, which can not only heat and moisture-proof the powder or cool and prevent caking, but also inject the conditioned water into the mixing mechanism through the conveying pipe; the electromagnetic valve controls the powder flow according to the mixing requirements, and the water outlet valve and the circulation valve cooperate to adjust the water pressure of the water circuit to ensure stable temperature; the internal of the powder rack integrates various pipeline interfaces, so that the water pipe, the conveying pipe and the spiral conveyor are arranged in layers, which not only avoids mutual interference but also facilitates maintenance. This system ensures the fluidity of the powder through temperature adjustment, realizes ratio control by combining precise metering, and effectively improves the resource utilization rate through the design of the circulating water circuit.

[0013] Furthermore, the aggregate assembly includes a conveyor belt, a screw conveyor, a control valve and a control motor. The control motor is fixedly connected to the intermediate aggregate bin, the control motor is drivingly connected to the control valve, the control valve is communicated with the intermediate aggregate bin, and both the conveyor belt and the screw conveyor are communicated with the control valve.

[0014] By adopting the above technical solutions, the control motor drives the conical valve core of the control valve to rotate through a coupling to adjust the opening amplitude of the discharge port of the intermediate aggregate bin; the conveyor belt is arranged at an inclination angle of 15°, and anti-slip convex lines are arranged on the surface for the directional transmission of blocky aggregates; the nested structure of the double spiral blades of the screw conveyor separates the powdered aggregates by reverse rotation to avoid material jamming; a flow splitting cavity is arranged inside the control valve to distribute the mixed aggregates output from the intermediate aggregate bin to the conveyor belt and the screw conveyor according to the particle size; the control motor feeds back the valve core angle in real time through an encoder to form a closed-loop control with the weighing sensor to ensure the dynamic ratio accuracy of aggregates with different particle sizes. This structure, through the gradual flow regulation of the conical valve core and the physical flow splitting design of the double conveying channels, completely solves the problem of aggregate mixing while reducing energy consumption.

[0015] Furthermore, the mixing mechanism includes a mixing assembly, a mixing tank and a mixing motor. The conveyor belt, the screw conveyor and the conveying pipe are all communicated with the mixing tank. The mixing motor is fixedly connected to the mixing tank, and the mixing motor is drivingly connected to the mixing assembly.

[0016] By adopting the above technical solution, the stirring motor drives the rotating disk of the stirring assembly to rotate through the coupling, driving the stirring rod to radially stir the material in the tank; the amplitude motor drives the sliding block to move up and down along the sliding rod through the amplitude screw rod, so that the articulated slider drives the rotating disk to produce axial vibration through the articulated rod, forming a composite motion mode of rotation and vibration superposition; the sliding frame and the sliding rod constitute a rigid support frame to ensure the stability of vibration conduction; the top of the stirring tank is connected to the conveyor belt, auger conveyor and conveying pipe to achieve the synchronous injection of aggregate, powder and temperature-adjusting water; the inner wall of the stirring tank is provided with guide ribs, which cooperate with the spiral blade structure of the stirring rod to enhance the convection shear effect of the material. This design effectively eliminates the mixing dead corner through the synergistic effect of mechanical vibration and rotary stirring, and the modular structure is easy to disassemble and clean.

[0017] Furthermore, the stirring assembly includes a sliding rod, a sliding frame, a rotating disk, a hinged rod, an articulated slider, an amplitude motor, an amplitude screw, a sliding block and a stirring rod. The sliding rod and the sliding frame are fixedly connected, the rotating disk and the sliding frame are rotatably connected, the stirring motor and the rotating disk are transmission-connected, the hinged rod and the rotating disk are hinged, the articulated rod and the articulated slider are articulated, the amplitude motor and the amplitude screw are transmission-connected, the amplitude motor and the sliding block are fixedly connected, the sliding block and the sliding rod are slidably connected, the articulated slider and the sliding block are slidably connected, and the rotating disk and the stirring rod are transmission-connected.

[0018] By adopting the above technical solution, when the stirring motor drives the rotating disk to rotate, the longitudinal vibration generated by the amplitude motor through the amplitude screw is converted into the axial swing of the stirring rod through the linkage mechanism of the articulated rod and the articulated slider; when the sliding block slides up and down along the guide rail of the sliding rod, the articulated slider is synchronously displaced in the sliding block, so that the rotating disk is superimposed with axial vibration during the rotation process; the stirring rod is connected to the rotating disk through the gear assembly structure, which can not only transmit the rotational torque but also move up and down along the axial direction of the vibration mechanism; the sliding frame serves as a rigid support frame, and the sliding frame ensures the stability of vibration transmission through the coordinated positioning of the sliding rod and the amplitude motor. This design allows the material to withstand radial shear and axial impact at the same time in the stirring tank, eliminates the stratification phenomenon caused by density differences through three-dimensional movement, and the independent control of the amplitude motor and the stirring motor can realize stepless adjustment of the stirring mode.

[0019] Furthermore, the detection mechanism includes a conductivity probe, a first elastic part, an electromagnetic block and a magnetic block. The conductivity probe and the magnetic block are tightly connected, the first elastic part and the electromagnetic block are tightly connected, the first elastic part and the magnetic block are tightly connected, the electromagnetic block and the magnetic block are tightly connected, the magnetic poles of the electromagnetic block and the magnetic block repel each other, the electromagnetic block and the stirring tank are tightly connected, and the magnetic block and the stirring tank are slidably connected.

[0020] By adopting the above technical solution, after the electromagnetic block is fixed to the stirring tank, the magnetic block is pushed to slide along the tank wall through the magnetic pole repulsion, so that the conductivity probe always adheres to the surface of the material; the first elastic member connects the electromagnetic block and the magnetic block to form an elastic suspension structure, which buffers vibration and maintains the contact stability of the probe during the impact of the flowing material; the conductivity probe collects the conductivity data of the material in real time and transmits it to the control system through the built-in circuit of the electromagnetic block; the sliding connection design of the magnetic block enables the probe to adaptively lift and lower with the height of the material liquid level, avoiding the probe being buried or disengaged during the stirring process. Through the synergistic effect of magnetic repulsion and the elastic member, this mechanism maintains the detection continuity under complex working conditions, and at the same time the contact pressure of the probe is dynamically adjustable, ensuring both the detection accuracy and preventing excessive wear of the probe.

[0021] Further, the discharging mechanism includes a discharging cylinder, a discharging box, a discharging valve and a rotating stirring rod. The discharging cylinder is communicated with the stirring truck, the discharging cylinder is communicated with the discharging box, the discharging box is communicated with the discharging valve, and the rotating stirring rod is arranged in the discharging cylinder and is rotatably connected to the discharging cylinder.

[0022] By adopting the above technical solution, the discharging cylinder serves as a material channel to connect the stirring truck and the discharging box. The rotating stirring rod is rotatably connected to the inner wall of the discharging cylinder through a bearing, and its spiral blades push the material to flow towards the discharging box when rotating; the discharging box serves as a temporary storage bin to receive the material from the discharging cylinder, and the discharging valve controls the opening and closing amplitude of the discharging port through an electric actuator to adjust the flow rate; the scraping brush of the rotating stirring rod is made of flexible material and fits the cylinder wall, continuously scraping the attached material when rotating with the rod body; the spiral flow disturbing vanes arranged on the inner wall of the discharging cylinder guide the material to generate a swirl through the inclined surface, and cooperate with the pushing action of the rotating stirring rod to achieve secondary mixing. This design combines mechanical agitation and fluid guidance, which not only prevents the material from caking and blocking during transportation, but also maintains the discharging uniformity. At the same time, the linkage control of the rotating stirring rod and the discharging valve can achieve accurate quantitative discharging.

[0023] Further, flow disturbing vanes are provided on the inner wall of the discharging cylinder. The upper part of the flow disturbing vane is an inclined surface, the lower part is an arc surface, and the flow disturbing vane is in a spiral shape as a whole. The flow disturbing vane is used for secondary stirring of the material during the discharging process to improve the discharging uniformity and prevent caking. A scraping brush is provided at the end of the rotating stirring rod, and the scraping brush fits the inner wall of the discharging cylinder. The scraping brush rotates with the rotating stirring rod and is used for cleaning the residual material attached to the cylinder wall.

[0024] By adopting the above technical solution, the inclined design of the spiral spoiler guides the material to produce a rotational flow, and the arc surface below reduces the movement resistance, forming a continuous stirring effect; the scraper brush at the end of the rotating stirring rod is made of elastic material to fit the cylinder wall, and continuously scrapes off the attachments as the rod rotates; the spiral arrangement trajectory of the spoiler and the propulsion direction of the rotating stirring rod form reverse convection, so that the material is mixed twice during the discharge process; the edge wavy structure of the scraper brush cooperates with the gap of the spoiler to ensure that there is no dead corner in the cleaning of the cylinder wall. This design improves the uniformity of discharging and avoids agglomeration through the dual effects of the spoiler's diversion enhancement and the dynamic cleaning of the scraper brush, which significantly reduces the amount of residue on the cylinder wall, while reducing material waste and equipment cleaning frequency.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] The powder component realizes quantitative powder transportation through the linkage of screw conveyor and electromagnetic valve. The spiral water pipe, heating box and cooling box form a closed-loop temperature control system. The water pump drives the water to flow through the circulation valve to form a reversible loop, which can adjust the powder temperature and avoid agglomeration. The corrugated partitions vertically arranged in the aggregate intermediate bin divide the independent compartments into different storage compartments for different aggregates. The conveyor belt and auger conveyor are adjusted by the control valve to convey block and powder aggregate in a direction respectively. The control motor accurately controls the valve opening to ensure the ratio accuracy. The main loading rack adopts a frame-type layered structure to separate the powder pipeline and the aggregate channel to avoid cross contamination and facilitate maintenance.

[0027] The stirring assembly drives the amplitude lead screw through the amplitude motor to drive the sliding block to move longitudinally, so that the hinged slider pushes the rotating disk through the hinged rod to produce axial vibration. At the same time, the stirring motor drives the rotating disk to rotate and drives the stirring rod to perform radial shearing. The sliding frame and the sliding rod form a rigid support frame to ensure vibration stability. The guide ribs on the inner wall of the stirring tank and the spiral blades of the stirring rod enhance material convection. The composite motion mode allows the material to withstand radial shear and axial vibration impact at the same time. The three-dimensional mixing eliminates density stratification, and the amplitude can be adjusted steplessly to adapt to different material characteristics.

[0028] The spiral spoiler on the inner wall of the discharge barrel guides the material swirl through the inclined surface and reduces the resistance through the curved surface, forming reverse convection with the spiral blades of the rotating stirring rod to achieve secondary mixing; the elastic scraping brush adheres to the barrel wall and cleans the residue with the rotation of the stirring rod; the discharge valve is linked to the stirring rod speed to control the flow. This structure allows the material to be continuously cut by the spoiler and pushed by the stirring rod, significantly improving the uniformity of the discharge and reducing the residue, while reducing the cleaning frequency.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figure 1 - Figure 7 As shown, the present invention provides a technical solution for a self-loading mixer truck with an automatic water content detection function:

[0039] The mixing truck includes a feeding mechanism 1, a detection mechanism 2, a mixing mechanism 3, a mixing truck 4, and a discharging mechanism 5. The feeding mechanism 1 is connected to the mixing mechanism 3. The detection mechanism 2 is fixedly connected to the mixing mechanism 3. The mixing truck 4 abuts against the discharging mechanism 5. The detection mechanism 2 is connected to the mixing mechanism 3. The detection mechanism 2 is connected to the discharging mechanism 5. The discharging mechanism 5 is connected to the mixing truck 4.

[0040] By adopting the above technical solution, the powder bin 111 of the feeding mechanism 1 realizes quantitative powder delivery through the cooperation of the screw conveyor 115 and the electromagnetic valve 116. The spiral wound water pipe 112 maintains the appropriate temperature of the powder under the control of the heating box 113 and the cooling box 114. The water pump 117 forms a closed-loop water circuit through the circulation valve 1110. The partition 131 of the aggregate intermediate bin 13 stores aggregates of different particle sizes separately. The conveyor belt 121 and the auger conveyor 122 transport blocky and powdery aggregates respectively. The control motor 124 drives the control valve 123 to achieve proportioning. The amplitude motor 316 of the mixing mechanism 3 drives the sliding block 318 to move up and down through the amplitude screw rod 317, so that the articulated slider 315 drives the rotating disk 313 to generate axial vibration through the articulated rod 314. At the same time, the mixing motor 33 drives the mixing rod 319 to rotate radially, forming a composite mixing mode. The conductivity probe 21 of the detection mechanism 2 forms a dynamic suspension structure with the electromagnetic block 23 through the first elastic member 22. The magnetic repulsion force makes the magnetic block 24 drive the probe to fit the inner wall of the mixing tank 32 in real time, monitor the change of the conductivity of the material and feedback it to the discharge valve 53. The spiral turbulator 511 in the discharge cylinder 51 guides the material to swirl through the inclined plane and reduces the resistance through the arc surface. The scraping brush 541 of the rotating stirring rod 54 scrapes the residue on the cylinder wall at the gap, and finally realizes the discharging uniformity.

[0041] Furthermore, the feeding mechanism 1 includes a powder component 11, an aggregate component 12, an aggregate intermediate bin 13, and a total feeding frame 14. The powder component 11, the aggregate component 12, and the aggregate intermediate bin 13 are uniformly and fixedly connected to the total feeding frame 14. The aggregate component 12 is connected to the aggregate intermediate bin 13. Both the powder component 11 and the aggregate component 12 are connected to the mixing mechanism 3. The aggregate intermediate bin 13 is provided with a partition 131, and the partition 131 is used to separate different aggregates stored in the aggregate intermediate bin 13.

[0042] By adopting the above technical solutions, the general feeding rack 14 uses a frame structure to integrally assemble the powder component 11, the aggregate component 12 and the aggregate intermediate bin 13. The powder box 111 is linked with the electromagnetic valve 116 through the screw conveyor 115 to complete the continuous and controllable conveying of the powder. The spirally wound water pipe 112 cooperates with the heating box 113 and the cooling box 114 to adjust the temperature of the powder. The corrugated partition 131 arranged inside the aggregate intermediate bin 13 divides it into independent compartments, which can store aggregates of different particle sizes simultaneously and avoid mixing. The conveying belt 121 and the auger conveyor 122 of the aggregate component 12 are respectively corresponding to the directional transmission of the bulk aggregate and the powdered aggregate. The control motor 124 realizes the ratio control of multi-category aggregates by adjusting the opening amplitude of the control valve 123. The whole set of system makes the powder conveying pipeline 119 and the aggregate conveying channel arranged in layers inside the general feeding rack 14 through modular design, which not only ensures that the material conveying paths do not interfere with each other, but also facilitates later maintenance and repair.

[0044] By adopting the above technical solutions, the powder box 111 is fixedly supported by the powder rack 1111. The screw conveyor 115 and the electromagnetic valve 116 cooperate to realize the quantitative conveying of the powder from the box body to the stirring mechanism 3. The spirally wound water pipe 112 adjusts the circulating water temperature through the heating box 113 and the cooling box 114. The water pump 117 drives the water flow through the circulation valve 1110 to form a reversible loop, which can not only heat and moisture-proof the powder or cool and prevent caking, but also inject the temperature-adjusted water into the stirring mechanism 3 through the conveying pipe 119. The electromagnetic valve 116 controls the powder flow according to the stirring requirements. The water outlet valve 118 and the circulation valve 1110 cooperate to adjust the water pressure of the water circuit to ensure temperature stability. The inside of the powder rack 1111 integrates various pipeline interfaces, so that the water pipe 112, the conveying pipe 119 and the screw conveyor 115 are arranged in layers, which not only avoids mutual interference but also facilitates maintenance. This system ensures the fluidity of the powder through temperature adjustment, realizes ratio control by combining precise metering, and effectively improves the resource utilization rate through the design of the circulating water circuit.

[0045] Further, the aggregate component 12 includes a conveyor belt 121, a screw conveyor 122, a control valve 123, and a control motor 124.

The control valve 123 communicates with the aggregate intermediate bin 13. Both the conveyor belt 121 and the screw conveyor 122 communicate with the control valve 123.

[0046] By adopting the above technical solution, the control motor 124 drives the conical valve core of the control valve 123 to rotate through a coupling, adjusting the opening amplitude of the discharge port of the aggregate intermediate bin 13; the conveyor belt 121 is arranged at an inclination angle of 15°, and anti-slip ridges are provided on the surface for the directional transmission of bulk aggregates; the double-screw blade nested structure of the screw conveyor 122 separates the powdered aggregates by reverse rotation to avoid material jamming; a flow splitting cavity is arranged inside the control valve 123 to distribute the mixed aggregates output from the aggregate intermediate bin 13 to the conveyor belt 121 and the screw conveyor 122 according to particle size; the control motor 124 feeds back the valve core angle in real time through an encoder, forming a closed-loop control with the weighing sensor to ensure the dynamic ratio accuracy of aggregates with different particle sizes. This structure, through the gradual flow regulation of the conical valve core and the physical flow splitting design of the double conveying channels, thoroughly solves the problem of aggregate mixing while reducing energy consumption.

[0047] Further, the stirring mechanism 3 includes a stirring component 31, a stirring tank 32, and a stirring motor 33. The conveyor belt 121, the screw conveyor 122, and the conveying pipe 119 all communicate with the stirring tank 32. The stirring motor 33 is fixedly connected to the stirring tank 32. The stirring motor 33 is drivingly connected to the stirring component 31.

[0048] By adopting the above technical solution, the stirring motor 33 drives the rotating disk 313 of the stirring component 31 to rotate through a coupling, driving the stirring rod 319 to perform radial stirring on the materials in the tank; the amplitude motor 316 pushes the sliding block 318 to move up and down along the sliding rod 311 through the amplitude screw rod 317, so that the articulated slider 315 drives the rotating disk 313 to generate axial vibration through the articulated rod 314, forming a composite motion mode of the superposition of rotation and vibration; the sliding frame 312 and the sliding rod 311 form a rigid support frame to ensure the stability of vibration conduction; the top of the stirring tank 32 is connected to the conveyor belt 121, the screw conveyor 122, and the conveying pipe 119 to realize the synchronous injection of aggregates, powders, and temperature-adjusted water; guide ribs are arranged on the inner wall of the stirring tank 32, cooperating with the spiral blade structure of the stirring rod 319 to enhance the convective shear effect of the materials. This design, through the synergistic action of mechanical vibration and rotary stirring, effectively eliminates the mixing dead angle, and at the same time the modular structure is convenient for disassembly and cleaning.

[0049] Further, the stirring assembly 31 includes a sliding rod 311, a sliding frame 312, a rotating disk 313, a hinged rod 314, a hinged slider 315, an amplitude motor 316, an amplitude lead screw 317, a sliding block 318, and a stirring rod 319. The sliding rod 311 and the sliding frame 312 are fixedly connected. The rotating disk 313 and the sliding frame 312 are rotatably connected. The stirring motor 33 and the rotating disk 313 are drivingly connected. The hinged rod 314 and the rotating disk 313 are hinged. The hinged rod 314 and the hinged slider 315 are hinged. The amplitude motor 316 and the amplitude lead screw 317 are drivingly connected. The amplitude motor 316 and the sliding block 318 are fixedly connected. The sliding block 318 and the sliding rod 311 are slidably connected. The hinged slider 315 and the sliding block 318 are slidably connected. The rotating disk 313 and the stirring rod 319 are drivingly connected.

[0050] By adopting the above technical solution, when the stirring motor 33 drives the rotating disk 313 to rotate, through the linkage mechanism of the hinged rod 314 and the hinged slider 315, the longitudinal vibration generated by the amplitude motor 316 via the amplitude lead screw 317 is converted into the axial swing of the stirring rod 319. When the sliding block 318 slides up and down along the guide rail of the sliding rod 311, the hinged slider 315 synchronously displaces within the sliding block 318, causing the rotating disk 313 to superimpose axial vibration during rotation. The stirring rod 319 is connected to the rotating disk 313 through a gear assembly structure, which can not only transmit the rotational torque but also move axially up and down with the vibration mechanism. The sliding frame 312 serves as a rigid support frame, and the cooperation and positioning of the sliding rod 311 and the amplitude motor 316 ensure the stability of vibration conduction. This design enables the material in the stirring tank 32 to simultaneously withstand radial shear and axial impact, eliminating the layering phenomenon caused by density differences through three-dimensional motion, and the independent control of the amplitude motor 316 and the stirring motor 33 can achieve stepless adjustment of the stirring mode.

[0051] Further, the detection mechanism 2 includes a conductivity probe 21, a first elastic member 22, an electromagnetic block 23, and a magnetic block 24. The conductivity probe 21 and the magnetic block 24 are fixedly connected. The first elastic member 22 and the electromagnetic block 23 are fixedly connected. The first elastic member 22 and the magnetic block 24 are fixedly connected. The electromagnetic block 23 and the magnetic block 24 are driven by magnetic poles repelling each other. The electromagnetic block 23 and the stirring tank 32 are fixedly connected. The magnetic block 24 and the stirring tank 32 are slidably connected.

[0052] By adopting the above technical solution, after the electromagnetic block 23 is fixed to the stirring tank 32, the magnetic block 24 is pushed to slide along the tank wall through the action of magnetic pole repulsion, so that the conductivity probe 21 always adheres to the surface of the material; the first elastic member 22 connects the electromagnetic block 23 and the magnetic block 24 to form an elastic suspension structure, which buffers vibration and maintains the contact stability of the probe during the impact of material flow; the conductivity probe 21 real-time collects the conductivity data of the material and transmits it to the control system through the built-in circuit of the electromagnetic block 23; the sliding connection design of the magnetic block 24 enables the probe to adaptively lift and lower with the height of the material liquid level, avoiding the probe being buried or disengaged during the stirring process. Through the synergistic action of magnetic repulsion force and elastic members, this mechanism maintains the detection continuity under complex working conditions, and at the same time the contact pressure of the probe is dynamically adjustable, ensuring both detection accuracy and preventing excessive wear of the probe.

[0053] Further, the discharging mechanism 5 includes a discharging cylinder 51, a discharging box 52, a discharging valve 53 and a rotating stirring rod 54. The discharging cylinder 51 is communicated with the stirring truck 4, the discharging cylinder 51 is communicated with the discharging box 52, the discharging box 52 is communicated with the discharging valve 53, and the rotating stirring rod 54 is arranged in the discharging cylinder 51 and is rotationally connected with the discharging cylinder 51.

[0054] By adopting the above technical solution, the discharging cylinder 51 serves as a material channel to connect the stirring truck 4 and the discharging box 52. The rotating stirring rod 54 is rotationally connected with the inner wall of the discharging cylinder 51 through a bearing, and its spiral blades push the material to flow towards the discharging box 52 when rotating; the discharging box 52 serves as a temporary storage bin to receive the material from the discharging cylinder 51, and the discharging valve 53 controls the opening amplitude of the discharging port through an electric actuator to adjust the flow rate; the scraping brush 541 of the rotating stirring rod 54 is made of flexible material and fits the cylinder wall, and continuously scrapes the attached material when rotating with the rod body; the spiral flow disturbing pieces 511 arranged on the inner wall of the discharging cylinder 51 guide the material to generate a swirl through an inclined surface, and cooperate with the pushing action of the rotating stirring rod 54 to achieve secondary mixing. This design combines mechanical agitation and fluid guidance, which not only prevents the material from caking and blocking during transportation, but also maintains the discharging uniformity. At the same time, the linkage control of the rotating stirring rod 54 and the discharging valve 53 can achieve quantitative and accurate discharging.

[0055] Further, flow disturbing pieces 511 are provided on the inner wall of the discharging cylinder 51. The upper part of the flow disturbing piece 511 is an inclined surface, and the lower part is an arc surface. The flow disturbing piece 511 is in an overall spiral shape and is used for secondary stirring of the material during the discharging process to improve the discharging uniformity and prevent caking. A scraping brush 541 is provided at the end of the rotating stirring rod 54, and the scraping brush 541 fits the inner wall of the discharging cylinder 51. The scraping brush 541 rotates with the rotating stirring rod 54 and is used for cleaning the residual material attached to the cylinder wall.

[0056] By adopting the above technical solution, the inclined surface design of the spiral spoiler 511 guides the material to produce a rotational flow, and the arc surface below reduces the movement resistance, forming a continuous stirring effect; the scraper brush 541 at the end of the rotating stirring rod 54 uses elastic material to fit the cylinder wall, and continuously scrapes off the attachments as the rod rotates; the spiral arrangement trajectory of the spoiler 511 and the propulsion direction of the rotating stirring rod 54 form a reverse convection, so that the material is secondary mixed during the discharge process; the edge wavy structure of the scraper brush 541 and the gap of the spoiler 511 are matched to ensure that there is no dead angle in the cleaning of the cylinder wall. This design, through the dual effects of the flow enhancement of the spoiler 511 and the dynamic cleaning of the scraper brush 541, not only improves the uniformity of the discharge to avoid agglomeration, but also significantly reduces the amount of residue on the cylinder wall, while reducing material waste and equipment cleaning frequency.

[0057] Working principle of the present invention:

[0058] The powder component 11 realizes quantitative powder delivery through the linkage of the screw conveyor 115 and the electromagnetic valve 116. The spiral water pipe 112 cooperates with the heating box 113 and the cooling box 114 to form a closed-loop temperature control system. The water pump 117 drives the water to flow through the circulation valve 1110 to form a reversible circuit, which can adjust the powder temperature and avoid agglomeration. The corrugated partition 131 vertically arranged in the aggregate intermediate bin 13 divides the independent bins to store different aggregates. The conveying belt 121 and the auger conveyor 122 are adjusted by the control valve 123 to convey block and powder aggregates in a direction respectively. The control motor 124 accurately controls the opening of the valve 123 to ensure the ratio accuracy. The total loading rack 14 adopts a frame-type layered structure to separate the powder pipeline and the aggregate channel to avoid cross contamination and facilitate maintenance. The stirring assembly 31 drives the amplitude screw rod 317 through the amplitude motor 316 to drive the sliding block 318 to move longitudinally, so that the hinged slider 315 pushes the rotating disk 313 through the hinged rod 314 to generate axial vibration, and at the same time, the stirring motor 33 drives the rotating disk 313 to rotate and drives the stirring rod 319 to perform radial shearing; the sliding frame 312 and the sliding rod 311 form a rigid support frame to ensure vibration stability; the guide ribs on the inner wall of the stirring tank 32 and the spiral blades of the stirring rod 319 enhance the convection of the material. The composite motion mode allows the material to withstand radial shear and axial vibration impact at the same time, and the three-dimensional mixing eliminates density stratification. The amplitude can be adjusted steplessly to adapt to different material characteristics. The spiral spoiler 511 on the inner wall of the discharge barrel 51 guides the material swirl through the inclined surface and reduces the resistance through the arc surface, and forms reverse convection with the spiral blades of the rotating stirring rod 54 to achieve secondary stirring; the elastic scraping brush 541 fits the barrel wall and rotates with the stirring rod to clean up the residue; the discharge valve 53 controls the flow rate in conjunction with the stirring rod speed. This structure allows the material to be continuously cut by the turbulent flow and pushed by the stirring rod, which significantly improves the uniformity of discharge and reduces residue, while also reducing the frequency of cleaning.
