Description

Technical Field

Aggregates include coarse aggregates such as crushed stones and fine aggregates such as sand. When mixing these raw materials together, a mixing device is required.

[0003] When mixing and preparing an anti-cracking concrete, water, cement, coarse aggregate, fine aggregate, and slag powder need to be mixed, and then reinforcing fibers, admixtures (polycarboxylate-based water reducer, triethanolamine, sodium thiosulfate, and polyethylene glycol), modified lignin, and saponin are sequentially added to the above mixture, so as to improve the anti-cracking and compressive strength of the overall concrete.

[0004] When mixing water, cement, coarse aggregate, fine aggregate, and slag powder, in order to improve the quality of the mixed concrete, the ratio between various raw materials is very important. When mixing concrete through the existing technology, the raw materials need to be proportioned through a special metering device first, and then the proportioned raw materials are taken out from the inside of the metering device and put into the inside of the mixing drum. Since there are multiple raw materials, the proportioning of multiple raw materials needs to be carried out multiple times, so that the operation process of mixing concrete is more troublesome.

[0031] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the attached drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the utility model.

[0032] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc. indicating the orientation or position relationship are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the referred components or elements must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the utility model.

[0033] Please refer to Figures 1 - 7As shown in the figure, the utility model is an anti-cracking concrete batching and mixing device, including a bracket 1. A mixing component 2 is rotatably connected inside the bracket 1. A stirring component 3 is rotatably connected inside the mixing component 2. A sealing component 4 is arranged on the outer surface of the mixing component 2. An adjustable batching component 5 is fixedly connected to the top of the bracket 1. A screw conveyor pipe 6 is arranged at the bottom of the adjustable batching component 5. A feeding component 7 corresponding to the sealing component 4 is arranged on the outer surface of the screw conveyor pipe 6.

[0034] By putting a kind of raw material into the adjustable batching component 5 according to a certain ratio, at this time, directly drive the screw conveyor pipe 6. Under the transportation of the screw conveyor pipe 6, the raw material inside the adjustable batching component 5 directly falls into the mixing component 2 through the feeding component 7. Then repeat the above operation and make another kind of raw material also directly put into the mixing component 2. When transporting the second kind of raw material, the stirring component 3 can stir the two kinds of raw materials. Then drive the sealing component 4 and make the sealing component 4 block the mixing component 2. At this time, the mixing component 2 and the stirring component 3 rotate synchronously and in opposite directions, so that the two kinds of raw materials inside the mixing component 2 are fully mixed together. During this period, a third kind of raw material can be put into the adjustable batching component 5. Then the mixing component 2 stops rotating. Next, repeat the above operation, so that a variety of raw materials are fully mixed together. The above whole process enables the device to mix a variety of raw materials in a cascading distribution manner.

[0035] By adjusting the adjustable batching component 5, the ratio of the raw material put into the adjustable batching component 5 to the overall ratio of the concrete to be mixed is exactly appropriate when the adjustable batching component 5 is filled with the raw material. Then, under the transportation of the screw conveyor pipe 6, it can be directly put into the mixing component 2. After the raw material inside the adjustable batching component 5 is transported, directly put the second kind of raw material according to the above working principle. After the second kind of raw material is also put into the mixing component 2, the mixing component 2 and the stirring component 3 cooperate to stir the two kinds of raw materials. During this period, the third kind of raw material can be directly put into the adjustable batching component 5. Then repeat the above operation and make a variety of raw materials mixed together in sequence. The above setting makes it convenient to directly transport the proportioned raw materials to the mixing component 2 for mixing when proportioning a variety of raw materials through the adjustable batching component 5, without the need to transport the raw materials multiple times. Therefore, the operation of mixing concrete with a variety of raw materials is relatively convenient.

[0036] In one embodiment, for the above-mentioned mixing component 2, the mixing component 2 includes a mixing cylinder 201. The two shaft ends of the mixing cylinder 201 are rotatably connected to the bracket 1. A feeding groove 202 is formed on the outer surface of the mixing cylinder 201. One shaft end of the mixing cylinder 201 is fixedly connected to a first gear 203. A second gear 204 is meshed with the outer surface of the first gear 203.

[0037] The first motor 205 drives the second gear 204 to rotate. The second gear 204 drives the mixing cylinder 201 to rotate inside the bracket 1 through the first gear 203, so that the raw materials can be better turned up and down inside the mixing cylinder 201. The rotatable mixing cylinder 201 cooperates with the stirring component 3 to improve the mixing effect of various raw materials.

[0038] In one embodiment, for the above-mentioned stirring component 3, the stirring component 3 includes a rotating shaft 301. The two ends of the rotating shaft 301 are respectively rotatably connected to the corresponding shaft ends at both ends of the mixing cylinder 201. A second motor 302 is fixedly installed on the other side of the bracket 1. The output end of the second motor 302 is fixedly connected to the rotating shaft 301. Stirring blades 303 are fixedly connected to the outer surface of the rotating shaft 301.

[0039] The second motor 302 can drive the rotating shaft 301 to rotate, so that the rotating shaft 301 drives the stirring blades 303 to rotate inside the mixing cylinder 201, so that the materials inside the mixing cylinder 201 can be stirred. At this time, the rotating directions of the mixing cylinder 201 and the rotating shaft 301 are opposite, and this setting makes the mixing effect of various materials better.

[0040] In one embodiment, for the above-mentioned sealing component 4, the sealing component 4 includes a shielding frame 401. The shielding frame 401 is fixedly connected to the outer surface of the mixing cylinder 201. The feeding groove 202 is inside the shielding frame 401. One side of the shielding frame 401 is rotatably connected to a bidirectional screw 402. A sealing plate 403 is threadedly connected to the outer surface of the bidirectional screw 402. The sealing plate 403 is movably connected to the shielding frame 401 and the feeding groove 202. A third motor 404 is fixedly installed at one end of the shielding frame 401. The output end of the third motor 404 is fixedly connected to the bidirectional screw 402.

[0041] By driving the third motor 404, the third motor 404 drives the bidirectional screw 402 to rotate, and the bidirectional screw 402 drives the two sealing plates 403 to block the feeding chute 202. This setting enables the normal feeding of raw materials into the mixing cylinder 201 through the feeding chute 202, and at the same time, the raw materials inside the mixing cylinder 201 will not leak out under the block of the sealing plates 403 when the mixing cylinder 201 rotates.

[0042] In one embodiment, for the adjustable material distribution assembly 5 described above, the adjustable material distribution assembly 5 includes a material distribution cylinder 501. The material distribution cylinder 501 is fixedly installed on the top of the bracket 1. The bottom end of the material distribution cylinder 501 is fixedly connected to the feeding end of the auger transport pipe 6. A first hydraulic cylinder 502 is fixedly installed at the bottom of the bracket 1. The output end of the first hydraulic cylinder 502 is fixedly connected to an adjustment cylinder 503. The adjustment cylinder 503 is movably connected to the material distribution cylinder 501. A limit post 504 is fixedly connected to the top of the bracket 1. The limit post 504 is movably connected to the adjustment cylinder 503. A scale groove 505 is formed on the outer surface of the material distribution cylinder 501.

[0043] By driving the first hydraulic cylinder 502, the adjustment cylinder 503 can move on the material distribution cylinder 501, so that the amount of materials that can be accommodated inside the adjustment cylinder 503 and the material distribution cylinder 501 can be adjusted according to the ratio of the raw materials. At the same time, the setting of the scale groove 505 makes the adjustment of the capacity inside the adjustment cylinder 503 and the material distribution cylinder 501 more accurate.

[0044] In one embodiment, for the feeding assembly 7 described above, the feeding assembly 7 includes a connecting plate 701. The connecting plate 701 is fixedly connected to the discharging end of the auger transport pipe 6. A second hydraulic cylinder 702 is fixedly installed on the top of the connecting plate 701. The output end of the second hydraulic cylinder 702 penetrates through the connecting plate 701 and is fixedly connected to a feeding hopper 703. The discharging end of the auger transport pipe 6 is movably connected to the feeding hopper 703. A fork-shaped dispersion groove 704 is formed inside the feeding hopper 703.

[0045] By driving the second hydraulic cylinder 702, the second hydraulic cylinder 702 drives the feeding hopper 703 to move downward so that the bottom end of the feeding hopper 703 can contact the top end of the shielding frame 401. This setting ensures that when the auger conveying pipe 6 transports raw materials into the mixing cylinder 201 through the feeding hopper 703, the raw materials will not fall outside the device. The fork-shaped dispersion tank 704 enables the raw materials transported by the auger conveying pipe 6 to fall straight into the mixing cylinder 201. Coupled with the continuous stirring of the stirring blades 303, the raw materials can be better mixed. The setting of the liftable feeding hopper 703 ensures that the feeding hopper 703 will not hinder the rotation of the mixing cylinder 201 driving the shielding frame 401.

[0046] In one embodiment, for the above-mentioned auger conveying pipe 6, a mounting plate 8 is fixedly connected to the bottom end of the auger conveying pipe 6. The mounting plate 8 is fixedly installed on the top of the bracket 1. A gantry 9 is fixedly installed on the top of the bracket 1, and the gantry 9 is fixedly connected to the outer surface of the auger conveying pipe 6.

[0047] The mounting plate 8 can fix the auger conveying pipe 6, and the gantry 9 can support the auger conveying pipe 6. This setting enables the overall stability of the auger conveying pipe 6 to be adjusted during the transportation of raw materials.

[0048] Through the above technical solutions: 1. By adjusting the adjustable batching component 5, when the raw materials put into the adjustable batching component 5 are filled, the ratio of the raw materials to the concrete to be mixed is exactly appropriate. Then, under the transportation of the auger conveying pipe 6, they can be directly put into the mixing component 2. When the raw materials inside the adjustable batching component 5 are transported out, the second type of raw materials can be directly put in according to the above working principle. The above setting enables the ratio of multiple raw materials to be directly mixed at the mixing site through the adjustable batching component 5, and then the proportioned raw materials are directly transported into the mixing component 2 under the transportation of the auger conveying pipe 6, making the operation of mixing concrete with multiple raw materials more convenient.

[0049] 2. By driving the first hydraulic cylinder 502, the adjusting cylinder 503 can move on the batching cylinder 501, so that the amount of materials that can be accommodated inside the adjusting cylinder 503 and the batching cylinder 501 can be adjusted according to the ratio of the raw materials. At the same time, the scale groove 505 makes the adjustment of the capacity inside the adjusting cylinder 503 and the batching cylinder 501 more accurate.

[0050] 3. The first motor 205 can drive the mixing drum 201 to rotate through the second gear 204 and the first gear 203, and the second motor 302 can drive the stirring blade 303 to rotate through the rotating shaft 301. At this time, the mixing drum 201 and the stirring blade 303 rotate in opposite directions. The above settings enable various raw materials to be better mixed together under the mutual cooperation of the mixing drum 201 and the stirring blade 303, thereby improving the effect of mixing concrete.
