Description
Technical Field
[0001] The present invention relates to the technical field of concrete mixing devices, and particularly relates to an automatic concrete feeding mixer. Background Art
[0002] Concrete refers to a general term for engineering composite materials in which aggregate is cemented into a whole by a cementing material. Usually, the term "concrete" refers to cement concrete obtained by mixing cement as the cementing material, sand and stone as the aggregate, and water in a certain proportion. There is no guiding device at the discharge port of the traditional concrete mixing device, resulting in easy blockage of the concrete at the discharge port after mixing, thus affecting the discharging of the concrete and reducing the usability of the concrete mixing device.
[0003] To solve the above problems, a Chinese patent with the publication number CN219543639U discloses a concrete mixing device, including a device main body, a mixing tank, a discharge port and a control valve. A mixing tank is provided inside the device main body, a discharge port is provided inside the device main body, a control valve is provided on the inner wall of the discharge port, a guiding mechanism is provided inside the device main body, and a covering mechanism is provided at the top of the device main body; the guiding mechanism includes a rotating rod, the rotating rod is rotatably connected inside the mixing tank, a mixing rod is fixedly connected to the outer wall of the rotating rod, and a scraping plate is fixedly connected to the outer wall of the rotating rod. In this concrete mixing device, under the combined action of the guiding mechanism and the conveying module, the spiral blade can rotate and discharge the concrete inside the discharge port, thereby reducing the blockage of the concrete inside the discharge port and improving the practicability of the device.
[0004] The above device has the following problems in the actual use process: the device fixes the mixing rod at a certain position on the rotating rod, so that the mixing rod can only be fixed at a certain point on the rotating rod to mix the concrete. However, due to the poor fluidity of the concrete, the concrete between adjacent two mixing rods cannot change its vertical position under the action of the mixing rod, that is, there is a mixing blind area inside the device main body, resulting in incomplete mixing of the concrete by the mixing rod and insufficient mixing of the concrete. Summary of the Invention
[0005] The present invention provides an automatic concrete feeding mixer to solve the problems of insufficient and incomplete mixing of the existing mixing device for concrete.
[0006] To achieve the above object, the present invention adopts the following technical solution: An automatic concrete feeding mixer, comprising a box body with an inlet and an outlet, and further comprising a mixing box and a mixing mechanism arranged inside the box body; the mixing box is fixedly connected to the box body, and the mixing box communicates with the inlet and the outlet respectively; the mixing mechanism comprises a rotating shaft, a plurality of mixing blades arranged at equal intervals along the axial direction of the rotating shaft, mixing components symmetrically arranged on both sides of the rotating shaft along the axial direction of the rotating shaft, a driving component for driving the rotating shaft to rotate, and a water guiding component for introducing water into the mixing box; the rotating shaft is rotatably connected to the mixing box; the mixing blades are fixedly connected to the rotating shaft; the mixing component comprises a guiding block, a plurality of mixing parts arranged at equal intervals along the length direction of the guiding block, a guiding hole opened on the mixing box, and a moving part for driving the guiding block to perform vertical reciprocating motion; the guiding block is slidably connected to the guiding hole; the mixing part comprises a moving block and a plurality of mixing blocks arranged at equal intervals along the length direction of the moving block; the moving block is fixedly connected to the guiding block; the mixing blocks are fixedly connected to the moving block.
[0007] The principle and advantages of this solution are:
[0008] 1. Put raw materials such as sand, gravel, and cement into the mixing box along the inlet, and at the same time inject water into the mixing box through the water guiding component. During the period when water is injected into the mixing box, the mixing blades are used to mix the raw materials such as sand, gravel, cement, and water in the mixing box to form concrete. Through the above process, while putting raw materials such as sand, gravel, and cement into the mixing box, water is introduced into the mixing box, so that the feeding speed of the concrete raw materials is moderate, ensuring that the concrete can be stirred more evenly under the action of the mixing blades, thereby enhancing the mixing effect of the concrete and improving the mixing efficiency of the concrete.
[0009] 2. During the stirring of the mixing blades, through the vertical reciprocating motion of the mixing blocks, on the one hand, the concrete in the mixing box can be stirred from the vertical direction, thereby expanding the mixing range of the concrete and enabling the concrete to be stirred from different directions. On the other hand, it can make the concrete have a certain fluidity in the vertical direction, so that the position of the concrete in the mixing box can be changed in the vertical direction, that is, the mixing blades can stir the concrete in the mixing box more comprehensively, ensuring the quality of the concrete after mixing.
[0010] Further, it further comprises a mixing part arranged on the mixing blocks; the mixing part includes a movable block, a vertical block, a plurality of horizontal blocks arranged at equal intervals along the length direction of the vertical block, and a driving unit for driving the movable block to perform reciprocating motion along the length direction of the mixing block; the movable block is slidably connected to the mixing block; the vertical block is connected to the movable block; the horizontal blocks are fixedly connected to the vertical block.
[0011] During the vertical reciprocating motion of the stirring block, the transverse block reciprocates along the length direction of the stirring block, thereby assisting the vertical stirring of the stirring block, that is, the transverse block can cut and disperse the piled-up concrete blocks. Through the above motion, under the action of the transverse block, the number of concrete piles can be reduced, thereby promoting the vertical movement of the concrete, enhancing the fluidity of the concrete, and ensuring that the concrete can be completely stirred under the combined action of the stirring block and the stirring blade.
[0012] Furthermore, it further includes a number of auxiliary parts arranged at equal intervals along the length direction of the stirring block; the auxiliary part includes an auxiliary shaft, a number of auxiliary blocks arranged at equal intervals along the circumferential direction of the auxiliary shaft, and an auxiliary unit for driving the auxiliary shaft to rotate; the auxiliary shaft is rotationally connected to the stirring block; the auxiliary block is fixedly connected to the auxiliary shaft.
[0013] During the vertical reciprocating motion of the stirring block, with the assistance of the auxiliary block rotating and cutting the concrete, the number of concrete piles agglomerated can be further reduced, making the concrete cut and dispersed more completely. That is, through the two different cutting and dispersing methods of the transverse cutting and dispersing of the transverse block and the rotating cutting and dispersing of the auxiliary block, it is ensured that the concrete is cut and dispersed more comprehensively and thoroughly, further improving the fluidity of the concrete and enhancing the stirring effect of the stirring block and the stirring blade on the concrete.
[0014] Furthermore, it further includes a linkage unit arranged on the movable block; the linkage unit includes a first wedge block, a vertical hole opened on the movable block, and a first spring; the vertical block is vertically slidably connected to the vertical hole; the first wedge block is fixedly connected to the vertical block; both ends of the first spring are respectively connected to the vertical block and the vertical hole; a second wedge block is fixedly connected to the auxiliary block; the second wedge block is located on the movement track of the first wedge block.
[0015] During the rotation of the second wedge block along with the auxiliary block, when the second wedge block acts on the first wedge block, it can drive the first wedge block to move vertically upward, and the first spring is compressed; when the second wedge block no longer abuts against the first wedge block, the first wedge block resets under the action of the first spring. Through the above motion, the first wedge block can drive the transverse block to perform vertical reciprocating motion. Therefore, during the reciprocating motion of the transverse block along the length direction of the stirring block, the transverse block can also perform vertical reciprocating motion. Through the vertical reciprocating motion of the transverse block, the acting force of the transverse block can be enhanced, making the transverse cutting and dispersing effect of the transverse block on the concrete better, the cutting and dispersing efficiency higher, further reducing the number of concrete piles agglomerated, and ensuring the fluidity of the concrete in the mixing tank.
[0016] Further, the guiding block is a water conduit, the moving block is a moving pipe, and the stirring block is a stirring pipe; the moving pipe communicates with the water conduit; the stirring pipe communicates with the moving pipe, and water guiding holes are formed in the stirring pipe; the water guiding assembly includes a water tank and water guiding parts symmetrically arranged on both sides of the water tank along the length direction of the water tank; the water tank is fixedly connected to the outer wall of the stirring tank; the water guiding part includes a piston cylinder, a piston block, and a power unit for driving the piston block to perform vertical reciprocating motion; the piston cylinder is fixedly connected to the outer wall of the stirring tank; the piston block is slidably connected to the piston cylinder; a water inlet pipe and a flexible pipe are communicated with the piston cylinder; the free end of the water inlet pipe communicates with the water tank; the free end of the flexible pipe communicates with the water conduit.
[0017] Through the mutual cooperation of the piston block and the piston cylinder, the water in the water tank can be pumped into the water conduit, so that the water flows through the moving pipe and the stirring pipe and finally discharges through the water guiding holes. Through the above movement, under the action of the piston cylinder, the water flow rate discharged from the water guiding holes can be increased, the range of water flowing between the concretes can be promoted to be wider, and thus the utilization rate of water is improved, so that the water is mixed more fully and evenly with raw materials such as sand, gravel, and cement, and the stirring quality of the concrete is further improved.
[0018] Since the water can also perform vertical reciprocating motion along with the stirring pipe, the acting range of the water in the stirring tank is further expanded, so that during the stirring of the concrete, the concrete in the stirring tank can be in uniform contact with the water. That is, the concrete will not solidify during the stirring process, the stirring effect of the concrete is comprehensively improved, and it is ensured that during the stirring of the concrete, the concrete is always in a flowable state, fully ensuring that the concrete can be mixed more thoroughly.
[0019] Further, the rotating shaft is a conduit; a water distribution part is also included; the water distribution part includes an annular pipe, a vertical pipe, and water distribution holes equidistantly formed in the conduit along the axial direction of the conduit; the annular pipe is fixedly connected to the outer wall of the stirring tank; an annular hole is formed in the annular pipe, a guiding hole is formed in the conduit, and the annular hole communicates with the guiding hole.
[0020] By introducing the water in the water tank into the conduit and finally discharging it along the water distribution holes, the distribution range of the water in the stirring tank is expanded again, so that the stirring blades can further enhance the stirring effect under the auxiliary action of the water, ensuring that the stirring blades can stir the concrete more efficiently and improving the quality of the stirred concrete.
[0021] Further, the annular pipe is a rubber pipe; the water distribution part also includes water distribution units symmetrically arranged on both sides of the conduit along the axial direction of the conduit; the water distribution unit includes a short shaft, a cam, and a power component for driving the short shaft to rotate; the short shaft is rotatably connected to the stirring tank; the cam is fixedly connected to the short shaft; the rubber pipe is located on the movement track of the cam.
[0022] When the cam rotates, when the convex part of the cam abuts against the rubber tube, the rubber tube deforms. When the convex part of the cam no longer abuts against the rubber tube, the rubber tube restores its deformation. Through the deformation of the rubber tube, the pressure inside the conduit can be increased. As a result, when water is discharged from the water distribution holes, the flow rate of the water is accelerated, and the distance that the water can flow is farther.
[0023] Through the above movement, after the water is discharged from the water distribution holes, the contact area between the water and raw materials such as sand, gravel, and cement will be further increased. As a result, the mixing effect between the water and raw materials such as sand, gravel, and cement is enhanced, enabling the water and raw materials such as sand, gravel, and cement to be more comprehensively mixed in the mixing tank, thereby further improving the utilization rate of water.
[0024] Furthermore, an adjusting member is also provided on the stirring tube; the adjusting member includes an arc-shaped wedge and a second spring; the arc-shaped wedge is slidably connected to the stirring tube, and the water distribution holes are located on the movement track of the arc-shaped wedge; the two ends of the second spring are respectively connected to the arc-shaped wedge and the stirring tube.
[0025] During the vertical reciprocating movement of the arc-shaped wedge along with the stirring tube, when the arc-shaped wedge moves to the position where the water distribution holes are located, the arc-shaped wedge can block the water distribution holes, thereby reducing the number of water discharged from the water distribution holes. After the number of water discharged from the water distribution holes is reduced, the pressure inside the conduit can be further increased. As a result, when the water is discharged from other water distribution holes, the flow rate of the water is faster and the flow distance is farther, comprehensively enhancing the auxiliary effect of the water on the stirring blades, ensuring that under the auxiliary action of the water, the stirring blades can stir the concrete more efficiently.
[0026] Furthermore, the driving unit includes a screw rod, a guide rod, a nut seat, and a driving member for driving the screw rod to rotate; the screw rod is rotatably connected to the inner wall of the stirring tube; the guide rod is fixedly connected to the inner wall of the stirring tube; the nut seat is threadedly connected to the screw rod, and the nut seat is slidably connected to the guide rod; the movable block is slidably connected to the water guide hole, and the movable block is fixedly connected to the nut seat.
[0027] During the rotation of the screw rod, the nut seat can make a reciprocating movement along the length direction of the guide rod. During the movement of the nut seat, the movable block moves synchronously.
[0028] Furthermore, the power unit is a third spring; the two ends of the third spring are respectively connected to the piston block and the piston cylinder; the cam abuts against the piston block.
[0029] During the rotation of the cam, when the convex part of the cam abuts against the piston block, the piston block makes a vertical reciprocating movement, and the third spring is compressed; when the convex part of the cam no longer abuts against the piston block, the piston block is reset under the action of the third spring, and the piston block makes a vertical downward movement. Therefore, the piston block can make a vertical reciprocating movement. Brief Description of the Drawings

[0059] Specific implementation process:
[0060] During the period when raw materials such as sand, gravel, and cement are put into the mixing tank 2 along the inlet 42, the servo motor 8 is started, and the output shaft of the servo motor 8 drives the drive shaft 9 to rotate. During the rotation of the drive shaft 9, the conduit rotates synchronously. During the rotation of the conduit, the third gear 37 rotates synchronously. During the rotation of the third gear 37, through the meshing of the third gear 37 and the fourth gear 38, the short shaft 24 is driven to rotate. During the rotation of the short shaft 24, the cam 25 rotates synchronously. During the rotation of the cam 25, when the convex portion of the cam 25 abuts against the piston block 20, the piston block 20 makes a vertical reciprocating motion, and the third spring 36 is compressed; when the convex portion of the cam 25 no longer abuts against the piston block 20, the piston block 20 is reset under the action of the third spring 36, and the piston block 20 makes a vertical downward motion. Therefore, the piston block 20 can make a vertical reciprocating motion.
[0061] Through the mutual cooperation of the piston block 20 and the piston cylinder 19, the water in the water tank 17 can be pumped into the water guide pipe, so that the water flows through the moving pipe and the mixing pipe and finally is discharged through the water guide holes. During the period when the water is injected into the mixing tank 2, the mixing blades 4 stir and mix the raw materials such as sand, gravel, cement, and water in the mixing tank 2 under the action of the conduit to form concrete. Through the above process, while putting raw materials such as sand, gravel, and cement into the mixing tank 2, water is introduced into the mixing tank 2, so that the feeding speed of the concrete raw materials is moderate, ensuring that the concrete can be stirred more evenly under the action of the mixing blades 4, thereby enhancing the mixing effect of the concrete and improving the mixing efficiency of the concrete.
[0062] At the same time, under the action of the piston cylinder 19, the water can accelerate the flow rate of the water discharged from the water guide holes, promote the water to flow in a wider range among the concrete, thereby improving the utilization rate of the water, making the water mix more fully and evenly with the raw materials such as sand, gravel, and cement, and further improving the mixing quality of the concrete.
[0063] During the agitation of the stirring blade 4, since the fourth gear 38 meshes with the first rack 40, the first gear 33 can drive the water guide pipe to perform vertical reciprocating motion. During the vertical reciprocating motion of the water guide pipe, the moving pipe moves synchronously. During the movement of the moving pipe, the stirring pipe moves synchronously. Through the vertical reciprocating motion of the stirring block 7, on the one hand, the concrete in the mixing tank 2 can be agitated in the vertical direction, thereby expanding the agitation range of the concrete, enabling the concrete to be agitated from different directions. On the other hand, it can make the concrete have a certain fluidity in the vertical direction, so that the position of the concrete in the mixing tank 2 can be changed in the vertical direction, that is, the stirring blade 4 can agitate the concrete in the mixing tank 2 more comprehensively, ensuring the quality of the concrete after mixing is completed.
[0064] Since the water can also perform vertical reciprocating motion along with the stirring pipe, the action range of the water in the mixing tank 2 is expanded, so that during the agitation of the concrete, the concrete in the mixing tank 2 can be evenly contacted with the water. That is, the concrete will not solidify during agitation, comprehensively improving the agitation effect of the concrete, ensuring that the concrete is always in a flowable state during agitation, and fully ensuring that the concrete can be mixed more thoroughly.
[0065] During the vertical reciprocating motion of the stirring pipe, through the meshing of the first gear 33 and the second rack 41, the first gear 33 drives the screw 28 to rotate. During the rotation of the screw 28, the nut seat 30 can perform reciprocating motion along the length direction of the guide rod 29. During the movement of the nut seat 30, the movable block 10 moves synchronously. During the movement of the movable block 10, the transverse block 12 moves synchronously. Through the reciprocating motion of the transverse block 12 along the length direction of the stirring block 7, the vertical agitation of the stirring block 7 is assisted, that is, the transverse block 12 can cut and disperse the agglomerated concrete. Through the above movements, under the action of the transverse block 12, the number of concrete accumulations can be reduced, thereby promoting the concrete to move in the vertical direction, enhancing the fluidity of the concrete, and ensuring that the concrete can be fully agitated under the combined action of the stirring block 7 and the stirring blade 4.
[0066] During the rotation of the first gear 33, due to the meshing of the first gear 33 with the second gear 34, the second gear 34 drives the worm 32 to rotate. During the rotation of the worm 32, since the worm gear 35 meshes with the worm 32, the worm gear 35 drives the auxiliary shaft 13 to rotate. During the rotation of the auxiliary shaft 13, the auxiliary block 14 moves synchronously. With the auxiliary effect of the auxiliary block 14 on the rotational cutting and dispersion of the concrete, the number of concrete aggregates can be further reduced, making the concrete more completely cut and dispersed. That is, through the two different cutting and dispersion methods of the transverse cutting and dispersion of the transverse block 12 and the rotational cutting and dispersion of the auxiliary block 14, it is ensured that the concrete is cut and dispersed more comprehensively and thoroughly, further improving the fluidity of the concrete and enhancing the mixing effect of the mixing block 7 and the mixing blades 4 on the concrete.
[0067] During the rotation of the second wedge block 16 with the auxiliary block 14, when the second wedge block 16 acts on the first wedge block 15, it can drive the first wedge block 15 to move vertically upward, and the first spring is compressed; when the second wedge block 16 no longer abuts against the first wedge block 15, the first wedge block 15 resets under the action of the first spring. Through the above movement, the first wedge block 15 can drive the transverse block 12 to perform vertical reciprocating motion. Therefore, during the reciprocating motion of the transverse block 12 along the length direction of the mixing block 7, the transverse block 12 can also perform vertical reciprocating motion. Through the vertical reciprocating motion of the transverse block 12, the acting force of the transverse block 12 can be enhanced, making the transverse cutting and dispersion effect of the transverse block 12 on the concrete better, the cutting and dispersion efficiency higher, further reducing the number of concrete aggregates, and ensuring the fluidity of the concrete in the mixing tank 2.
[0068] Under the action of the vertical pipe 22, the water in the water tank 17 can be introduced into the conduit and finally discharged along the water distribution holes 23, further expanding the distribution range of the water in the mixing tank 2, enabling the mixing blades 4 to further enhance the mixing effect under the auxiliary action of the water, ensuring that the mixing blades 4 can mix the concrete more efficiently, and improving the quality of the mixed concrete.
[0069] During the rotation of the cam 25, when the convex part of the cam 25 abuts against the rubber tube, the rubber tube deforms, and when the convex part of the cam 25 no longer abuts against the rubber tube, the rubber tube returns to its original shape. Through the deformation of the rubber tube, the pressure in the conduit can be increased, so that when the water is discharged from the water distribution holes 23, the flow rate of the water is accelerated and the water can flow a longer distance.
[0070] Through the above movement, after the water is discharged from the water distribution holes 23, the contact area between the water and the raw materials such as sand, gravel, and cement will be further increased, thereby enhancing the mixing effect between the water and the raw materials such as sand, gravel, and cement, enabling the water and the raw materials such as sand, gravel, and cement to be more comprehensively mixed in the mixing tank 2, and further improving the utilization rate of the water.
[0071] During the vertical reciprocating motion of the arc-shaped wedge block 26 along with the mixing tube, when the arc-shaped wedge block 26 moves to the position where the water diversion hole 23 is located, the arc-shaped wedge block 26 can block the water diversion hole 23, thereby reducing the amount of water drained from the water diversion hole 23. After the amount of water drained from the water diversion hole 23 is reduced, the pressure inside the conduit can be further increased, thereby prompting the water to flow out from other water diversion holes 23 at a faster speed and a farther distance, comprehensively enhancing the auxiliary effect of the water on the mixing blades 4, and ensuring that the mixing blades 4 can mix the concrete more efficiently with the assistance of water.
[0072] In summary, by expanding the flow range of water and the mixing range of concrete, it is ensured that the concrete can be mixed more evenly and fully during the mixing process, comprehensively improving the quality of the mixed concrete.
