Technical Field

[0001] The utility model relates to the field of building construction equipment, in particular to a batching and mixing device for lightweight aggregate concrete. Background Art

[0002] Lightweight aggregate concrete is mostly made of natural sand or light sand as fine aggregate, artificial ceramsite as coarse aggregate, cement and admixtures. Compared with traditional concrete, it has the characteristics of light weight, high strength and heat preservation. The proportion of corresponding components varies according to the different parts of the building structure. At the same time, during the mixing and stirring of the components, it is also necessary to ensure the uniformity of the distribution of each component as much as possible to prevent the accumulation of aggregates and segregation. Therefore, during the mixing of the components, how to achieve uniform feeding on the basis of ensuring an effective ratio is a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0003] The utility model aims to provide a batching and mixing device for lightweight aggregate concrete. The utility model has a simple structure and can achieve uniform feeding of multiple components according to the proportion during the material mixing process, thereby effectively improving the mixing effect and quality of lightweight aggregate concrete.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A concrete aggregate batching and mixing device, comprising a mixing chamber and a motor arranged on the top of the mixing chamber and used to drive a mixing rod in the mixing chamber, a batching box is also fixedly arranged on the top of the mixing chamber, a feed pipe with one end closed and the other end connected to the batching box is radially arranged on the top of the mixing chamber, one end of a transverse shaft coaxially arranged on the closed end of the feed pipe is connected to the mixing rod through a transmission mechanism, and a screw auger is arranged on the other end;

[0006] The feed pipe is provided with a feed discharge port at the bottom surface close to the closed end.

[0007] Preferably, the stirring rod includes a shaft rod transmission-connected to the output end of the motor and several stirring rods arranged on the shaft rod, a sealing chamber is provided on the top of the shaft rod, and the transmission mechanism includes a driving bevel gear arranged on the shaft rod and located inside the sealing chamber, and a driven bevel gear meshing with the driving bevel gear is provided after the horizontal axis passes through a preset through hole of the sealing chamber.

[0008] Preferably, the external sliding sleeve of the feed pipe is provided with a sleeve for covering the feed opening, and the bottom wall of the sleeve is fixedly connected with a fixing seat.

[0009] The fixing seat is transmission connected to the shaft rod through an adjusting mechanism.

[0010] Preferably, the adjustment mechanism comprises an adjustment frame detachably arranged on the bottom surface of the fixing seat, the bottom surface of the adjustment frame is rotatably connected with a rolling wheel, and the shaft rod is provided with a toggle arc rod for pushing the rolling wheel.

[0011] Preferably, grooves for slidingly fitting the adjustment frame are provided on both sides of the fixing seat, and a plurality of adjustment screw holes arranged along the axial direction of the sleeve are provided at the lower end of the fixing seat, and the bolts penetrate the adjustment frame and are screwed into the adjustment screw holes.

[0012] Preferably, a flange is provided at one end of the sleeve away from the stirring rod, and a spring is sleeved on the feeding pipe, with one end connected to the flange and the other end connected to a preset convex plate on the feeding pipe.

[0013] The working process of the utility model is as follows: according to the single processing concrete amount of the mixing bin, the amount of cement, fine aggregate, coarse aggregate and admixture is calculated, and then the cement is added to the mixing bin and mixed with the target amount of water, and the other components are added to the batching box respectively, and then the motor is turned on, the motor drives the stirring rod to rotate, and at the same time, through the meshing transmission of the active bevel gear and the driven bevel gear, the horizontal axis and the auger are driven to rotate, and then the components in the batching box are pushed to the discharge port. Since the discharge port is temporarily blocked by the sleeve, the material cannot be discharged directly. Only when the stirring rod drives the toggle arc rod to move and contact the rolling wheel, the toggle arc rod squeezes and pushes the rolling wheel so that the adjustment frame drives the fixed seat and the sleeve to move back to the stirring rod, and then the discharge port is exposed instantly and a certain amount of material is discharged. When the toggle arc rod and the rolling wheel are separated, the sleeve is reset under the elastic force of the spring and continues to block the discharge port, so as to ensure that the material is discharged multiple times and evenly and participates in mixing and stirring.

[0014] The staff can adjust the size of the discharge port opening each time according to the particle size of the material or the process design: that is, move the adjustment frame relative to the fixed seat. When the adjustment frame is farther away from the stirring rod, the area of ​​the discharge port opening each time is smaller, and the corresponding volume of the discharged material is smaller; when the adjustment frame is farther away from the stirring rod, the area of ​​the discharge port opening each time is larger, and the corresponding volume of the discharged material is larger. Finally, screw the bolts into the adjustment screw holes at the corresponding positions to ensure the immediate relative position of the adjustment frame and the fixed seat.

[0015] The setting of the rolling wheel can cooperate with the curved surface shape of the toggle arc rod. On the one hand, the surface contact between the two can be converted into the linear movement of the rolling wheel and the sleeve. On the other hand, the rotation of the rolling wheel can reduce the contact friction loss between the two.

[0016] Compared with the prior art, the utility model has the following advantages: the utility model has a simple structure, can realize uniform feeding of multiple components according to the proportion during the material mixing process, and effectively improves the mixing effect and quality of lightweight aggregate concrete.

[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] like Figure 1-4 As shown, a concrete aggregate batching and mixing device comprises a mixing chamber 1 with a motor 2 on the top and a mixing rod 51 arranged inside the mixing chamber, wherein the mixing rod 51 comprises a shaft connected to the output end of the motor 2 and a plurality of mixing rods arranged on the shaft, a sealing chamber 52 is arranged on the top of the shaft, and an active bevel gear 35 is arranged on the shaft body located inside the sealing chamber 52;

[0023] The mixing chamber 1 is also provided with a batching box 3 on the top outside, and a feed pipe 32 is provided radially on the top inside the mixing chamber 1, with one end closed and the other end connected to the batching box 3. A transverse shaft 31 is coaxially arranged on the closed end of the feed pipe 32, one end of which passes through a preset through hole on the sealing chamber 52 and is provided with a driven bevel gear 36 meshing with the driving bevel gear 35, and the other end is provided with an auger 34;

[0024] The feed pipe 32 is provided with a discharge port 33 on the bottom surface near the closed end, and a sleeve 41 is slidably sleeved on the outside of the feed pipe 32 for covering the discharge port 33. The sleeve 41 has a flange 37 at one end away from the stirring rod 51, and a spring 42 is sleeved on the feed pipe 32, with one end connected to the flange 37 and the other end connected to a preset convex plate on the feed pipe 32.

[0025] The bottom wall of the sleeve 41 is fixedly connected with a fixing seat 43, and grooves for slidingly fitting the adjustment frame 44 are provided on both sides of the fixing seat 43. The lower end of the fixing seat 43 is provided with a plurality of adjustment screw holes 46 arranged along the axial direction of the sleeve 41. Bolts 47 penetrate the adjustment frame 44 and are screwed into the adjustment screw holes 46. The bottom surface of the adjustment frame 44 is rotatably connected with a rolling wheel 45, and the shaft rod is provided with a toggle arc rod 53 for pushing the rolling wheel 45.

[0026] The working process of the utility model is as follows: according to the single concrete processing amount of the mixing bin, the amount of cement, fine aggregate, coarse aggregate and admixture is calculated, and then the cement is added to the mixing bin and mixed with the target amount of water, and the other components are added to the batching box respectively, and then the motor 2 is turned on, the motor 2 drives the stirring rod 51 to rotate, and at the same time, through the meshing transmission of the active bevel gear 35 and the driven bevel gear 36, the horizontal shaft 31 and the auger 34 are driven to rotate, and then the components in the batching box 3 are pushed to the discharge port 33. Since the discharge port 33 is temporarily blocked by the sleeve 41, the material cannot be discharged directly. Only when the stirring rod 51 drives the toggle arc rod 53 to move and contact the rolling wheel 45, the toggle arc rod 53 squeezes and pushes the rolling wheel 45 so that the adjustment frame 44 drives the fixed seat 43 and the sleeve 41 to move back to the stirring rod 51, thereby instantly exposing the discharge port 33 and discharging a certain amount of material. When the arc rod 53 and the rolling wheel 45 are separated, the sleeve 41 is reset under the elastic force of the spring 42 and continues to block the discharge port 33, thus ensuring multiple and uniform discharge of materials and mixing and stirring.

[0027] The staff can adjust the size of the discharge port 33 each time it is opened according to the particle size of the material or the process design: that is, the adjustment frame 44 is moved relative to the fixed seat 43. When the distance between the adjustment frame 44 and the stirring rod 51 is larger, the area of ​​the discharge port 33 each time it is opened is smaller, and the volume of the corresponding discharged material is also smaller; when the distance between the adjustment frame 44 and the stirring rod 51 is smaller, the area of ​​the discharge port 33 each time it is opened is larger, and the volume of the corresponding discharged material is also larger. Finally, the bolt 47 is screwed into the adjustment screw hole 46 at the corresponding position to ensure the instant relative position of the adjustment frame 44 and the fixed seat 43.

[0028] The setting of the rolling wheel 45 can cooperate with the curved surface shape of the toggle arc rod 53. On the one hand, the surface contact between the two can be converted into linear movement of the rolling wheel 45 and the sleeve 41. On the other hand, the rotation of the rolling wheel 45 can reduce the contact friction loss between the two.
