Description

Technical Field

[0001] This invention relates to the field of concrete processing technology, and more particularly to concrete batching equipment. Background Technology

[0002] Concrete is made by mixing aggregates (sand, stone), cement, water, admixtures and additives in a certain proportion; a concrete batching machine can combine various raw materials in a certain proportion.

[0003] Most current concrete batching machines measure the output by weighing or flow rate. However, this method has low controllability and poor uniformity, which is not conducive to the initial mixing of raw materials and continuous operation. At the same time, the batching process generates a lot of dust and debris splashing; the on-site construction environment is poor, which has a significant impact on the health of operators.

[0004] Therefore, based on our engineering practice, we have made certain improvements to it. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of inconvenience and insufficient effect of existing concrete batching devices, and to propose a concrete batching device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A uniform discharge component is provided at the lower end of the hopper;

[0009] The hopper is equipped with a mixing component.

[0010] In some embodiments, the uniform discharge assembly includes a rectangular discharge port and a discharge drum rotatably disposed within the rectangular discharge port;

[0011] The discharge drum is evenly divided into several axially arranged material troughs.

[0016] The upper end of the nut and the lower end of the ring edge maintain a movable gap.

[0017] In some embodiments, a slanted baffle is provided inside the discharge nozzle.

[0018] In some embodiments, the first conveyor belt is provided with herringbone-shaped protrusions;

[0019] The discharge end of the first conveyor belt faces the center and is inclined downwards.

[0020] In some embodiments, the mixing assembly includes two relatively rotating feed rollers, the blades of which are arc-shaped;

[0021] When in operation, the two feeding wheels lift the material upwards towards the center.

[0022] In some embodiments, a disturbance component is provided inside the hopper;

[0023] The disturbance component includes a rotating rod with two opposing helical blades.

[0024] In some embodiments, a sampling component is provided on the hopper;

The vertically sliding discharge nozzle avoids scattering and splashing of materials during fall and reduces dust generation. Rollers are set on both sides of the lower end of the discharge nozzle to achieve self-adaptation and better material discharge.

[0065] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0066] Reference Figure 1-20 The concrete batching device includes multiple silos 2 mounted on a support 1. Two opposing first conveyor belts 3 are mounted below the silos 2, and a collection hopper 4 is mounted below the discharge end of the first conveyor belts 3.

[0067] This application adopts a four-hopper mode, with four hoppers 2; correspondingly, there are two first conveyor belts 3, each first conveyor belt 3 corresponding to the two hoppers 2 above it.

[0068] In use, the material is divided into two groups, which are then gathered from both sides towards the middle; this is equivalent to a conventional single conveyor belt, which facilitates the initial mixing of the material and reduces the load on the first conveyor belt 3; at the same time, it provides a basic environment for the subsequent component setup.

[0069] Furthermore, a uniform discharge component 5 is provided at the lower end of the hopper 2 to control the discharge speed and discharge volume.

[0070] Furthermore, a mixing component 6 is installed inside the collecting hopper 4 to mix the materials coming from both sides, which can improve production quality.

[0071] Correspondingly, a second conveyor belt 8 is provided below the collection hopper 4 to transport the pre-mixed ingredients away.

[0072] In some embodiments, the uniform discharge assembly 5 includes a rectangular discharge port 501 and a discharge drum 502 rotatably disposed within the rectangular discharge port 501.

[0073] like Figure 11-14 As shown; a rectangular discharge port 501 is provided below the hopper 2, and several axially arranged material troughs 503 are evenly distributed on the discharge drum 502; the material is discharged by the rotation of the discharge drum 502.

[0074] During batching, the discharge speed and discharge volume can be controlled by controlling the drive speed; compared with weighing discharge, it is simpler, more reliable, and has controllable continuity and uniformity.

[0075] Understandably, the central shaft of the discharge drum 502 extends through to the outside of the rectangular discharge port 501 and is connected to a motor or other drive device for driving.

[0076] It is understandable that the specifications of the discharge drum 502 are matched and set according to the particle size of different materials.

[0077] In some embodiments, a discharge nozzle 7 is vertically slidably disposed below the hopper 2 to compensate for and close the distance between the rectangular discharge port 501 and the first conveyor belt 3, thereby preventing the material from scattering and splashing during its fall and reducing the generation of dust.

[0078] It is understandable that the discharge nozzle 7 is mounted on the outside of the rectangular discharge port 501 and slides.

[0079] Furthermore, rollers 701 are provided on both sides of the lower end of the discharge nozzle 7, and the rollers 701 are in contact with the first conveyor belt 3. During operation, the discharge nozzle 7 vibrates up and down with the movement of the first conveyor belt 3, which can achieve self-adaptation and better material feeding.

[0080] In addition, a feed port 702 is provided on the side of the discharge nozzle 7 along the conveying direction to allow materials on the conveyor belt to pass through normally.

[0081] It is understandable that the outermost nozzle 7 has a material passage 702 on its inner side; the middle nozzle 7 needs to have material passages 702 at both ends.

[0082] Furthermore, a door panel 703 or a door curtain is hinged to the material outlet 702 closest to the discharge end.

[0083] In some embodiments, the top of the discharge nozzle 7 is provided with a ring edge 704, and a screw 705 is vertically provided on the outer side of the hopper 2; correspondingly, a nut 706 is provided after the screw 705 penetrates the ring edge 704; the screw 705 provides a guide and restriction for the up and down movement of the discharge nozzle 7.

[0084] Understandably, a clearance is maintained between the upper end of the nut 706 and the lower end of the ring edge 704 to allow the discharge nozzle 7 to move up and down.

[0085] In some embodiments, a slanted baffle 707 is provided inside the discharge nozzle 7.

[0086] like Figure 9 , 10 As shown; two sets of inclined baffles 707 are provided, located on the inner walls on both sides respectively; the falling material is blocked by the inclined baffles 707, which can reduce the occurrence of agglomeration; at the same time, the material can be appropriately gathered towards the center side, which is more conducive to conveying.

[0087] Furthermore, reinforcing ribs 708 are provided on the outside of the discharge nozzle 7.

[0088] Preferably, the reinforcing ribs 708 are staggered to improve the overall strength.

[0089] In some embodiments, the first conveyor belt 3 is provided with herringbone protrusions 301.

[0090] like Figure 6 , 7 As shown in Figure 18, the herringbone protrusion 301 can improve strength; at the same time, during the conveying operation, the herringbone protrusion 301 makes the discharge nozzle 7 produce uniform up and down bumps, which is more conducive to material feeding.

[0091] In some embodiments, the discharge ends of the two first conveyor belts 3 are oriented towards the center and inclined downwards, which further facilitates material feeding.

[0092] In some embodiments, the mixing assembly 6 includes two relatively rotating feed rollers 601.

[0093] like Figure 19 , 20 As shown; in the working state, the two feeding wheels 601 lift the material upwards towards the center.

[0094] In some embodiments, a top baffle 602 is provided above the hopper 4 to prevent material from being thrown out.

[0095] In some embodiments, the blades of the feeding wheel 601 are configured in an arc shape, which makes it easier to lift materials.

[0096] Furthermore, several reinforcing rings 603 are provided on the outer side of the feeding wheel 601 to ensure strength and reliability.

[0097] In some embodiments, a disturbance component 9 is provided in the hopper 2 to avoid material bridging and other situations that affect material discharge.

[0098] Specifically, the disturbance component 9 includes a rotating rod 901, on which two opposing spiral blades 902 are provided; during operation, the spiral blades 902 gather the material inward or push it outward.

[0099] Furthermore, an agitator 903 is also provided on the rotating rod 901.

[0100] It is important to note that the length of the stirring rod 903 should not be too long; it should be slightly longer than the diameter of the spiral blade 902 to achieve a better arch-breaking effect.

[0101] In some embodiments, a sampling component 10 is provided on the hopper 2.

[0102] It should be noted that the sampling component 10 is located in the lower middle part of the hopper 2 to sample the material at that location.

[0103] It is understandable that it is more convenient to sample the upper layer material directly from the upper layer; the lower layer material can be discharged directly; therefore, it is set to sample the middle and lower layers.

[0104] In some embodiments, the sampling assembly 10 includes a sampling port 1001 disposed on the outer wall of the silo 2, a sampling cylinder 1002 inserted into the sampling port 1001, and the sampling port 1001 and the sampling cylinder 1002 are connected by a flange 1003 disposed opposite to each other.

[0105] Furthermore, a pointed cone end 1004 is provided on the inner end side of the sampling cylinder 1002, an upper opening 1005 is provided on the sampling cylinder 1002, and a handle 1006 is provided on the outer end side of the sampling cylinder 1002.

[0106] Under normal conditions, the sampling cylinder 1002 is fixedly installed and secured with bolts through the flange 1003. When sampling is required, the bolts are removed, the sampling cylinder 1002 is rotated several times so that its upper opening 1005 faces upward, and it is pulled outward to expose the upper opening 1005 and the sample is taken out.

[0107] Preferably, when the sample is taken out, the position of the upper opening 1005 matches the sampling port 1001 to seal the inside of the sampling port 1001.

[0108] Preferably, the flange 1003 of the sampling cylinder 1002 is provided with up and down direction markings.

[0109] In some embodiments, the support 1 includes a vertical column 101, an upper frame 102, and a middle frame 103; a sealing plate 104 is provided on the lower outer side of the support 1 for sealing and dust prevention.

[0110] Among them, the sealing plate 104 is a detachable installation type.

[0111] Furthermore, the sealing plate 104 is configured to open and close as a door.

[0112] The middle frame 103 is equipped with an inner frame that matches the rectangular discharge port 501, which further ensures the overall strength and reliability.

[0113] Preferably, a sealing plate 104 is installed on the middle frame 103 to further seal the area and maintain a good construction environment.

[0114] In use, materials are added to four collection hoppers 4 respectively; the rotation speed of the discharge drums 502 of different collection hoppers 4 is controlled according to the designed mixing ratio; during the batching process, the discharge nozzles 7 vibrate up and down as the first conveyor belt 3 conveys the materials; after passing through two first conveyor belts 3, the materials enter the collection hoppers 4 and are mixed by the mixing component 6; then, a second conveyor belt 8 is set below the collection hoppers 4 to convey the materials out.

[0115] In this invention, the hopper 2, in conjunction with the first conveyor belt 3, divides the material into two groups, which gather the material from both sides toward the middle, facilitating the initial mixing of the material and reducing the load on the first conveyor belt 3, thus providing a basic environment for subsequent component setup; a uniform discharge component 5 is provided to control the discharge speed and discharge amount; and a mixing component 6 is provided to mix the materials coming from both sides, thereby improving production quality.

[0116] In this invention, the uniform discharge component 5 can control the discharge speed and discharge volume by controlling the drive speed, which is simpler, more reliable, and has controllable continuity and uniformity; the vertically sliding discharge nozzle 7 avoids the scattering and splashing of materials during falling and reduces dust generation; rollers 701 are set on both sides of the lower end of the discharge nozzle 7 to achieve self-adaptation and better material discharge; the discharge nozzle 7 is equipped with a slanted baffle 707 to reduce the occurrence of agglomeration; at the same time, it can appropriately gather materials towards the center side, which is more conducive to conveying.

[0117] In this invention, the mixing component 6, when in operation, lifts the material upwards towards the center, achieving a better initial mixing effect; the blades of the feeding wheel 601 are set in an arc shape, making it easier to lift the material; several reinforcing rings 603 are provided to ensure strength and reliability; a sealing plate 104 is provided on the outer side of the bracket 1 for sealing and dust prevention.
