Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, specifically a precision batching device for commercial concrete production. Background Technology

[0002] CN215319571U discloses a precision batching commercial concrete mixing production system, relating to the field of mixing device technology, specifically including a batching box and a mixing box. This precision batching commercial concrete mixing production system, through the arrangement of an inclined plate, a cylinder, a baffle, a T-block, a gravity sensor, and a conical block, achieves convenient and precise batching. During use, the movable end of the first electric push rod retracts, causing the T-block to move inside the T-slot, rotating the baffle, and allowing the material to fall onto the conical block inside the cylinder. When the gravity sensor reaches a certain value, the movable end of the first electric push rod extends, causing the baffle to abut against the inclined plate, and the movable end of the second electric push rod retracts, separating the conical block from the cylinder, allowing the material to slide off the conical block, thus achieving the purpose of convenient and precise batching.

[0003] However, the technology in this patent still has some shortcomings in the process of ingredient preparation:

[0004] 1. In this patent, the first electric push rod controls the baffle to rotate and flip, so that the material falls on the cone block. When the gravity sensor reaches the set value, the second electric push rod controls the cone block to separate from the cylinder, so that the weighed material is discharged into the mixing box. Since the batching process needs to be controlled by two electric push rods respectively, and the control process is complicated, the assembly cost of the batching device is high.

[0005] 2. In this patent, although the mixing tank is equipped with a component that can stir and mix the materials, and the mixing tank itself can be flipped for material discharge, the two need to be controlled by different electrical devices, which further increases the assembly cost of the batching device.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example: Figure 1-6 As shown, this utility model provides a precision batching device for commercial concrete production, including a batching tank 1. The opening end of the batching tank 1 is detachably installed with a tank cover 11 via a flange and bolts (not shown in the figure). A feeding pipe 12 is fixedly installed on the tank cover 11. The main raw materials for commercial concrete production can be added into the batching tank 1 through the feeding pipe 12. A batching hopper 13 is fixedly installed on the tank cover 11. The batching hopper 13 can store auxiliary materials for commercial concrete production. A batching mechanism 2 is set inside the tank cover 11. By setting the batching mechanism 2, the batching mechanism 2 can realize the configuration of auxiliary materials for commercial concrete production. A mixing and feeding mechanism 3 is set on the batching tank 1. The mixing and feeding mechanism 3 can mix and directionally discharge the configured auxiliary materials and main materials.

[0028] The batching mechanism 2 includes a batching cylinder 21, which is fixedly mounted on the top wall of the tank cover 11. A connecting hole 22 is provided in the middle of the tank cover 11. The batching hopper 13 is connected to the inner cavity of the batching cylinder 21 through the connecting hole 22. Through the connecting hole 22, the auxiliary materials in the batching hopper 13 can fall into the batching cylinder 21. A first control seat 23 and a second control seat 24 are provided inside the batching cylinder 21. A connecting rod 25 is fixedly mounted between the first control seat 23 and the second control seat 24. The connecting rod 25 is driven by the first control seat 23. Material control seat 23 and material control seat 24 rise. When material control seat 23 rises to the bottom of the batching hopper 13, because the diameter of material control seat 23 is smaller than the bottom inner diameter of the batching hopper 13, the auxiliary material in the batching hopper 13 can fall down through the edge of material control seat 23 to the top of material control seat 24 and be temporarily stored in the batching cylinder 21. When material control seat 23 and material control seat 24 descend, material control seat 23 enters the batching cylinder 21, and material control seat 24 disengages from the batching cylinder 21. The auxiliary materials temporarily stored in cylinder 21 fall downwards into the mixing tank 1. Sealing rings 26 are fixedly installed on the outer walls of both the first and second material control seats 23 and 24. The outer walls of the sealing rings 26 are in movable contact with the inner wall of the mixing cylinder 21. By installing the sealing rings 26, the sealing performance between the first and second material control seats 23 and the mixing cylinder 21 is improved. A weighing sensor 27 is fixedly installed on the lower surface of the second material control seat 24. By installing the weighing sensor 27, the weighing sensor 27 can read the temperature of the material from the second material control seat 24. The weight of the auxiliary material above the material seat 24 is used to achieve precise dispensing (the relevant technology has been disclosed in the comparative case CN215319571U, and will not be repeated here). A cylinder 28 is fixedly installed on the inner wall of the can lid 11. A connecting frame 29 is fixedly installed on the piston end of the cylinder 28. One end of the connecting frame 29 is fixedly connected to the lower surface of the second material control seat 24. By activating the cylinder 28, the piston end of the cylinder 28 can cause the first material control seat 23 and the second material control seat 24 to rise or fall in the dispensing cylinder 21 through the connecting frame 29.

[0029] The mixing and feeding mechanism 3 includes a rotating shaft 31, which is rotatably mounted inside the mixing tank 1. A support rod 36 is fixedly mounted on the inner wall of the mixing tank 1, and a sleeve 37 is fixedly mounted on one end of the support rod 36. The rotating shaft 31 passes through the sleeve 37 and is rotatably connected to it. By setting the support rod 36 and the sleeve 37, the support rod 36 and the sleeve 37 can support the rotating shaft 31. A first dispersing disc 32 and a second dispersing disc 33 are respectively fixedly mounted on one end of the rotating shaft 31. The diameter of the second dispersing disc 33 is larger than the diameter of the first dispersing disc 32, and the diameter of the second dispersing disc 33 is smaller than the inner diameter of the mixing tank 1. The first dispersing disc 32 is located below the mixing cylinder 21. By driving the rotating shaft 31 to rotate, the rotating shaft 31 can... The first dispersing disc 32 and the second dispersing disc 33 are rotated. The auxiliary materials discharged downward through the mixing cylinder 21 fall onto the first dispersing disc 32. The rotation of the first dispersing disc 32 disperses the auxiliary materials through centrifugal force, and at the same time, the auxiliary materials fall onto the second dispersing disc 33. The rotation of the second dispersing disc 33 disperses the auxiliary materials again through centrifugal force. The auxiliary materials after the two dispersions fall to the bottom of the mixing tank 1 and are dispersed on the main materials. The other end of the rotating shaft 31 is fixedly equipped with a stirring shaft 34. Several stirring paddles 35 are fixedly equipped on the stirring shaft 34. By driving the rotating shaft 31 to rotate, the rotating shaft 31 can make the stirring shaft 34 and the stirring paddles 35 stir the main materials and the dispersed auxiliary materials in the mixing tank 1, and the auxiliary materials are mixed with the main materials.

[0030] The bottom of the batching tank 1 is fixedly provided with a conveying channel 38 and a guide hopper 39. The bottom of the guide hopper 39 is connected to one end of the inner cavity of the conveying channel 38. Through the guide hopper 39, the main material and auxiliary material after stirring and mixing enter the conveying channel 38 under the action of the guide hopper 39. A rotating roller 4 is rotatably installed inside the conveying channel 38. A spiral blade 41 is fixedly provided on the rotating roller 4. The outer wall of the spiral blade 41 is in contact with the inner wall of the conveying channel 38. A discharge pipe 42 is fixedly provided at the other end of the inner cavity of the conveying channel 38. By driving the rotating roller 4 to rotate, the rotating roller 4 causes the spiral blade 41 to rotate. The rotation of the spiral blade 41 can directionally convey the main material and auxiliary material. The conveyed main material and auxiliary material can be discharged into the commercial concrete mixing tank through the discharge pipe 42.

[0031] A servo motor 43 is fixedly installed at the open end of the mixing tank 1. A rotating rod 44 is fixedly installed at the drive output end of the servo motor 43. A bevel gear 45 is fixedly installed at one end of the rotating rod 44 and the middle of the rotating shaft 31. The two bevel gears 45 are meshed and connected. A toothed pulley 46 is fixedly installed at one end of the rotating rod 44 near the servo motor 43 and one end of the rotating roller 4. A transmission toothed belt 47 is installed between the two toothed pulleys 46. By starting the servo motor 43, the drive shaft of the servo motor 43 can make the rotating rod 44 rotate. The rotating rod 44 can make the rotating shaft 31 rotate through the bevel gear 45. The rotating rod 44 can make the rotating roller 4 rotate through the toothed pulley 46 and the transmission toothed belt 47.

[0032] Working principle: In the process of commercial concrete production, the operator first adds the main material for commercial concrete production to the batching tank 1 through the feeding pipe 12, and then stores the auxiliary materials in the batching hopper 13;

[0033] Subsequently, cylinder 28 is activated, causing its piston end to extend. Cylinder 28, via connecting bracket 29, causes the first material control seat 23 and the second material control seat 24 to rise vertically within the mixing cylinder 21. Once the first material control seat 23 passes through the connecting hole 22 and enters the bottom of the mixing hopper 13, the second material control seat 24 remains within the mixing cylinder 21. At this point, cylinder 28 is closed, and the auxiliary material within the mixing hopper 13 falls downwards along the edge of the first material control seat 23 to above the second material control seat 24. The auxiliary material temporarily... The material is stored in the mixing cylinder 21. At the same time, the weighing sensor 27 reads the weight of the temporarily stored auxiliary material. When the preset value is reached, the cylinder 28 is started again, causing the piston end of the cylinder 28 to retract. The piston end of the cylinder 28 causes the first material control seat 23 and the second material control seat 24 to descend vertically through the connecting frame 29. When the second material control seat 24 is separated from the mixing cylinder 21, the auxiliary material between the first material control seat 23 and the second material control seat 24 is discharged from the bottom of the mixing cylinder 21 to the first dispersing plate 32.

[0034] At the same time, the operator starts the servo motor 43. The drive shaft of the servo motor 43 causes the rotating rod 44 to rotate. The rotating rod 44 causes the rotating shaft 31 to rotate through the bevel gear 45. The rotating shaft 31 causes the first dispersion disk 32 and the second dispersion disk 33 to rotate. At the same time, the stirring shaft 34 causes the stirring paddle 35 to rotate. The rotating rod 44 causes the rotating roller 4 and the spiral blade 41 to rotate through the toothed pulley 46 and the transmission toothed belt 47.

[0035] The rotation of the first dispersing disc 32 disperses the auxiliary materials through centrifugal force, and at the same time, the auxiliary materials fall onto the second dispersing disc 33. The rotation of the second dispersing disc 33 disperses the auxiliary materials again through centrifugal force. The auxiliary materials after the two dispersions fall onto the main material at the bottom of the mixing tank 1.

[0036] The stirring paddle 35 stirs the main material and the dispersed auxiliary material at the bottom of the mixing tank 1, so that the auxiliary material and the main material are mixed.

[0037] The mixed main and auxiliary materials fall into the conveying channel 38 through the guide hopper 39. The spiral blades 41 convey the mixed main and auxiliary materials in a directional manner. The conveyed main and auxiliary materials can be discharged into the commercial concrete mixing tank through the discharge pipe 42.
