Description

Technical Field

[0001] This utility model belongs to the field of concrete processing technology, and in particular relates to a crack-resistant concrete processing and mixing device. Background Technology

[0002] The crack-resistant concrete processing and mixing equipment is a device specifically designed to produce concrete with excellent crack resistance. By precisely controlling the raw material ratio, mixing process, and the mixing of crack-resistant additives, it significantly improves the crack resistance of the concrete, preventing cracks from occurring during use due to drying shrinkage, temperature changes, or external forces.

[0003] Currently, in order to accelerate the concrete processing and mixing efficiency, the target amount of crack-resistant additive is usually added directly into the device and mixed with the concrete. Although this improves the concrete mixing efficiency, the reaction time between the crack-resistant additive and the concrete is short, resulting in a poor reaction effect between the crack-resistant additive and the concrete, and thus the crack resistance of the mixed concrete cannot reach the best level.

[0004] Therefore, we propose a crack-resistant concrete processing and mixing device. Utility Model Content

[0029] like Figures 1-5 As shown in the figure, an embodiment of the present invention proposes a crack-resistant concrete processing and mixing device, including a mixing tank 1 and a tank cover 10 disposed on the upper end face of the mixing tank 1. A support frame 2 is disposed on the upper end face of the tank cover 10, and a drive motor 3 is disposed on the upper end face of the support frame 2. The output end of the drive motor 3 is connected to a drive shaft 4. One end of the drive shaft 4 extends through the support frame 2 to the inside of the mixing tank 1. A crack-resistant agent adding component 5 is disposed above the tank cover 10. The crack-resistant agent adding component 5 includes an intermittent adding element 51 and a sealing element 52. The intermittent adding element 51 is located on one side of the drive motor 3, and the sealing element 52 is disposed on the intermittent adding element 51.

[0030] It should be noted that an agitator is provided inside the mixing tank 1, and the drive shaft 4 extending to the inside of the mixing tank 1 is connected to the agitator inside the mixing tank 1.

[0031] By setting the crack-resistant agent addition component 5, crack-resistant agent can be intermittently added to the concrete being mixed inside the mixing tank 1. This can prolong the reaction time between the crack-resistant agent and cement inside the mixing tank 1 and make the crack-resistant agent and cement mix more evenly. This helps to improve the reaction effect between the crack-resistant agent and cement, thereby improving the crack resistance of the concrete. In addition, the addition rate of the crack-resistant agent is proportional to the mixing speed of the concrete inside the mixing tank 1, which can make the crack-resistant agent added to the inside of the mixing tank 1 mix more evenly with the concrete.

[0032] The intermittent addition component 51 includes an anti-cracking agent storage cylinder 511, a first gear 512, a second gear 513, a delivery pipe 514, a first drainage channel 515, a first liquid inlet 516, a second drainage channel 517, and a second liquid inlet 518. The sealing component 52 includes a sealing plug 521, a fixing block 522, a receiving port 523, an elastic connecting plate 524, a limiting block 525, a limiting port 526, a fixing plate 527, an elastic vertical plate 528, and a pressing block 529. The sealing plug 521 is located above the anti-cracking agent storage cylinder 511.

[0033] The anti-cracking agent storage cylinder 511 is disposed on the upper end face of the support frame 2. The first gear 512 is rotatably connected to the upper end face of the tank cover 10. The second gear 513 is sleeved on the drive shaft 4 and meshes with the first gear 512. The delivery pipe 514 is disposed on the lower end face of the anti-cracking agent storage cylinder 511. The first drainage groove 515 is opened on the upper end face of the first gear 512. The first liquid inlet 516 is opened at the bottom inner side of the first drainage groove 515. One end of the delivery pipe 514 away from the anti-cracking agent storage cylinder 511 passes through the support frame 2 and abuts against the bottom inner side of the first drainage groove 515. The second drainage groove 517 is opened on the upper end face of the tank cover 10. The second drainage groove 517 is concentric with the first drainage groove 515. The second liquid inlet 518 is opened at the bottom inner side of the second drainage groove 517.

[0034] It should be noted that the second diversion channel 517 has the same diameter as the first diversion channel 515. The first diversion channel 515 and the second diversion channel 517 are designed to collect the anti-cracking agent overflowing on the first gear 512 and the tank cover 10. The collected anti-cracking agent will be transported to the inside of the mixing tank 1 through the first liquid inlet 516 and the second liquid inlet 518 on the first diversion channel 515 and the second diversion channel 517.

[0035] By setting the first gear 512 and the second gear 513, the kinetic energy of the drive motor 3 driving the stirring component inside the mixing tank 1 can be transmitted to the first gear 512, so that the first gear 512 can rotate on the tank cover 10.

[0036] The sealing plug 521 is inserted into the inner top of the crack-resistant agent storage cylinder 511. The fixing block 522 is disposed on the upper end face of the sealing plug 521 and presses against the upper end face of the crack-resistant agent storage cylinder 511. The receiving port 523 is opened on the outer wall surface of the sealing plug 521. The elastic connecting plate 524 is disposed on the inner top of the receiving port 523. The limiting block 525 is disposed on the elastic connecting plate 524. The limiting port 526 is opened. On the crack-resistant agent storage cylinder 511, the limiting block 525 on the elastic connecting plate 524 is inserted into the limiting port 526 on the crack-resistant agent storage cylinder 511, the fixing plate 527 is disposed on the crack-resistant agent storage cylinder 511, the elastic vertical plate 528 is disposed on the fixing plate 527, the pressing block 529 is disposed on the elastic vertical plate 528, and the pressing block 529 on the elastic vertical plate 528 is inserted into the limiting port 526 on the crack-resistant agent storage cylinder 511.

[0037] The sealing element 52 can seal the upper surface of the crack-resistant agent storage cylinder 511, thereby preventing dust from falling from the top of the crack-resistant agent storage cylinder 511 into the inside of the crack-resistant agent storage cylinder 511, which would reduce the purity of the crack-resistant agent inside the crack-resistant agent storage cylinder 511. In addition, the sealing element 52 can be disassembled and installed by pressing, which is simple and efficient. The receiving port 523 provides space for the deformation of the elastic connecting plate 524. The elastic connecting plate 524, the limiting block 525, and the limiting port 526 can lock the position of the sealing plug 521 inserted inside the crack-resistant agent storage cylinder 511.

[0038] The outer wall of the sealing plug 521 has a groove located below the receiving port 523. A sealing ring 6 is installed inside the groove, with one end of the sealing ring 6 away from the groove pressing against the inner wall of the crack-resistant agent storage cylinder 511. The sealing ring 6 improves the sealing performance between the sealing plug 521 and the inner wall of the crack-resistant agent storage cylinder 511.

[0039] The lower corner of the limiting block 525 away from the elastic connecting plate 524 is chamfered, and the fixing plate 527 is located above the limiting opening 526.

[0040] Working principle:

[0041] When it is necessary to mix the concrete inside the mixing tank 1, the drive motor 3 is started. The drive motor 3 drives the mixing components inside the mixing tank 1 to mix the concrete via the drive shaft 4. During the rotation of the drive shaft 4, the second gear 513 rotates, and the second gear 513 drives the first gear 512 to rotate. When the first inlet 516 on the first gear 512 rotates to the bottom of the delivery pipe 514, the crack-resistant agent inside the crack-resistant agent storage cylinder 511 flows into the mixing tank 1 through the delivery pipe 514, the first inlet 516, and the second inlet 518. The concrete is mixed inside the mixing tank 1. When the delivery pipe 514 is misaligned with the first inlet 516 on the first gear 512, the outlet of the delivery pipe 514 will abut against the bottom of the inner side of the first diversion groove 515, and the anti-cracking agent inside the anti-cracking agent storage cylinder 511 will stop being delivered to the mixing tank 1. Finally, the above steps are repeated to achieve intermittent delivery of anti-cracking agent to the inner side of the mixing tank 1. When it is necessary to add anti-cracking agent to the anti-cracking agent storage cylinder 511, the elastic vertical plate 528 is pressed towards the anti-cracking agent storage cylinder 511, so that the pressing block 529 on the elastic vertical plate 528 extends into the anti-cracking agent storage cylinder 511. The limiting port 526 on the anti-cracking agent storage cylinder 511 is used to push out the limiting block 525 inside the limiting port 526. During the pushing process, the elastic connecting plate 524 bends inward toward the receiving port 523. When the limiting block 525 is pushed out of the limiting port 526, the fixing block 522 is lifted, thereby pulling out the sealing plug 521 on the fixing block 522 from the anti-cracking agent storage cylinder 511. Then, the anti-cracking agent is added from the top of the anti-cracking agent storage cylinder 511. After the anti-cracking agent is added, the sealing plug 521 is inserted back into the anti-cracking agent storage cylinder 511. At the top, when the chamfer of the upper limit block 525 of the sealing plug 521 abuts against the inner top wall of the crack-resistant agent storage cylinder 511, the limiting block 525 is pressed down by the fixing block 522. At this time, the limiting block 525 is subjected to force, causing the elastic connecting plate 524 to move completely into the receiving port 523. When the position of the limiting block 525 corresponds to the limiting port 526 on the crack-resistant agent storage cylinder 511, the elastic connecting plate 524 pushes the limiting block 525 into the limiting port 526 on the crack-resistant agent storage cylinder 511 through its own elastic potential energy, and at this time the elastic connecting plate 524 returns to its original position.
