[0032] At present, the addition of glass fiber in traditional concrete placing equipment is often done manually or by simple mechanical conveying.

[0033] However, this method not only easily leads to uneven distribution of glass fibers, but may also cause entanglement and damage of glass fibers, thereby affecting the overall performance of concrete.

[0034] In order to solve the technical problem, the present invention provides a concrete placing equipment.

[0035] See also Figure 1 and Figure 2 In one embodiment of the present invention, the concrete distribution equipment includes a distribution hopper 100, a feeding assembly 200, a quantitative bottle 300 and a premixing mechanism 400. The top of the distribution hopper 100 is provided with a feeding port 101, and the bottom of the distribution hopper 100 is provided with a distribution port 102. The feeding port 101 and the distribution port 102 are connected through a mixing space 103 formed in the distribution hopper 100; the feeding assembly 200 is installed on the distribution hopper 100; the quantitative bottle 300 includes an air inlet 301 and an air outlet 302 which are connected; the feeding assembly 200 includes a spraying port 201 and a feeding port 202 which are connected, the spraying port 201 is connected to the mixing space 103, the feeding port 202 is connected to the air outlet 302, and the air inlet 301 It is connected to an external air pumping mechanism; the premixing mechanism 400 includes a mounting portion and a rotating portion, the mounting portion is mounted outside the distribution hopper 100, the rotating portion extends from the mounting portion into the mixing space 103, and the rotating portion is rotatably connected to the distribution hopper 100 at the connection point between the injection port 201 and the mixing space 103; wherein the distribution hopper 100, the premixing mechanism 400 and the feeding assembly 200 all extend in the horizontal direction, and the quantitative bottle 300 extends in the vertical direction; the feeding port 101 is used to feed concrete aggregate into the mixing space 103, the quantitative bottle 300 is used to load glass fiber balls, and the air pumping mechanism is used to pump air to the air inlet 301, so that the glass fiber balls pass through the air outlet 302 and the feed port 202, and are sprayed into the mixing space 103 from the injection port 201.

[0036] It should be noted that vertical refers to Figure 1 The up and down directions in the perspective, horizontal refers to Figure 1 In the left and right directions of the cloth hopper 100 in the viewing angle, the longitudinal direction refers to Figure 1 In the front-to-back direction of the distribution hopper 100 in the viewing angle, the horizontal direction and the vertical direction are located in the same horizontal plane, and the horizontal plane where the horizontal direction and the vertical direction are located is perpendicular to the vertical direction.

[0037] Specifically, the concrete distribution equipment includes a distribution hopper 100, which has a feeding port 101 at the top and a distribution port 102 at the bottom, which are connected in the middle by a mixing space 103. The feeding port 101 is used to receive and introduce concrete aggregates, and the connection between the feeding port 101 and the distribution port 102 allows the concrete aggregates to reach the premixing mechanism 400 through the mixing space 103. This ensures the continuous and efficient delivery of concrete aggregates, and provides sufficient mixing space 103, laying a foundation for the subsequent addition of glass fiber balls.

[0038] The feeding assembly 200 is installed on the material distribution hopper 100. The feeding assembly 200 is connected to the mixing space 103 through the spray port 201. The feed port 202 of the feeding assembly 200 is connected to the air outlet 302 of the quantitative bottle 300 to ensure that the glass fiber balls enter the mixing space 103 under controlled conditions, and the spray port 201 is used to spray the glass fiber balls directly into the mixing space 103. Through the use of the feeding assembly 200, the device can achieve precise control of the glass fiber, ensuring that it enters the mixing space 103 constantly and evenly, overcoming the instability of manual control in the traditional method and avoiding the problem of fiber winding.

[0039] The quantitative bottle 300 has an air inlet 301 and an air outlet 302, and is connected to an external air pump mechanism through the air inlet 301. Air is injected through the air pump mechanism, and the glass fiber balls can enter the feed port 202 of the feeding assembly 200 from the quantitative bottle 300 through the air outlet 302. By utilizing the stability of the air flow, the glass fiber balls are kept in a good flow state, transported from the quantitative bottle 300 to the spray port 201, and finally sprayed into the mixing space 103, achieving accurate and uniform addition, greatly reducing the problem of glass fiber balls being damaged during transportation.

[0040] The premixing mechanism 400 includes a mounting portion and a rotating portion. The mounting portion is fixed to the outside of the material distribution hopper 100, while the rotating portion extends into the mixing space 103 and is connected to the section where the injection port 201 is located. The function of the premixing mechanism 400 is to promote further uniform mixing of the materials in the mixing space 103. Through the movement of the rotating portion, the effective combination of the glass fiber balls and the concrete aggregate in the mixing space 103 is enhanced, ensuring uniform mixing of the concrete components and improving the mixing efficiency and quality.

[0041] The material distribution hopper 100, the premixing mechanism 400 and the feeding assembly 200 extend in the horizontal direction, while the quantitative bottle 300 is arranged vertically, which not only optimizes the overall structure of the equipment, but also improves the ease of operation and space utilization efficiency, shortens the flow path of the glass fiber balls, and reduces the complexity of operation and labor costs.

[0042] More specifically, the quantitative bottle 300 can accurately confirm the amount of glass fiber balls added. In addition, the air inlet 301 at the top of the quantitative bottle 300 can ensure that the glass fiber balls in the quantitative bottle 300 are emptied during the air intake process, thereby ensuring the quality of the concrete product.

[0043] In the technical solution provided by the present invention, the accuracy and uniformity of adding glass fiber balls to concrete are significantly improved through the coordinated work of the distribution hopper 100, the feeding assembly 200, the quantitative bottle 300 and the premixing mechanism 400. The distribution hopper 100 ensures the continuous and efficient delivery of concrete aggregates, and provides sufficient mixing space 103, laying a foundation for the subsequent addition of glass fiber balls. The spray port 201 of the feeding assembly 200 is connected to the mixing space 103, so that the glass fiber balls are sprayed into the mixing space 103 under controlled conditions, thereby overcoming the instability and fiber entanglement problems of manual control in the traditional method. In addition, the air inlet 301 of the quantitative bottle 300 is connected to the external pump air mechanism, and the stability of the air flow is used to ensure the good flow state of the glass fiber balls, which greatly reduces the damage of the glass fiber balls during the transportation process and improves the mixing efficiency and quality. The rotating part of the premixing mechanism 400 further promotes the uniform mixing of materials in the mixing space 103, enhances the effective combination between different components, and ensures the quality and performance of the concrete product.

[0044] Please continue reading Figure 1 and Figure 2 In an embodiment of the present invention, the feeding assembly 200 includes a feeding main pipe 210, a feeding head 220 and a feeding branch pipe 230. The feeding main pipe 210 is installed on one side of the material distribution hopper 100. A material guide channel extending in the transverse direction is arranged in the feeding main pipe 210. A feeding port 202 connected to the material guide channel is opened on the feeding main pipe 210. The material guide channel is connected to the feeding head 220 through the feeding branch pipe 230. The connection between the feeding branch pipe 230 and the feeding head 220 is spaced apart from the feeding port 202. The feeding head 220 extends in the longitudinal direction, one end of the feeding head 220 extends into the mixing space 103 and is detachably installed on the material distribution hopper 100. A spray port 201 is opened at one end of the feeding head 220 facing the mixing space 103.

[0045] Specifically, the feeding assembly 200 includes a feeding main pipe 210, a feeding head 220 and a feeding branch pipe 230. The feeding main pipe 210 is installed on one side of the material distribution hopper 100, and a material guide channel extending in the transverse direction is provided inside the feeding main pipe 210. The direction of the material guide channel is coordinated with the structure of the material distribution hopper 100, which is convenient for the stable transportation of materials. The feeding main pipe 210 is provided with a feeding port 202, which is connected with the material guide channel, so that the incoming glass fiber balls can be guided to the injection port 201, ensuring the smooth entry of the glass fiber balls in the feeding stage and avoiding the accumulation and blockage of the glass fiber balls.

[0046] The material guide channel is connected to the feeding head 220 through the feeding branch pipe 230. The feeding branch pipe 230 plays a role of connection and transition. Its position is separated from the feeding port 202 to optimize the flow path of the glass fiber balls and prevent the glass fiber balls from backflowing or pressure changes from interfering with the transportation of the glass fiber balls. The feeding branch pipe 230 allows the glass fiber balls to smoothly transition from the feeding main pipe 210 to the feeding head 220.

[0047] The feeding head 220 extends in the longitudinal direction and is detachably mounted on the material distribution hopper 100, which improves the maintenance and cleaning efficiency of the feeding head 220. One end of the feeding head 220 extends into the mixing space 103 and is provided with a spraying port 201 to ensure that the glass fiber balls are accurately sprayed into the mixing space 103. The directionality and targeting of the glass fiber balls when entering the mixing space 103 are ensured, the irregular scattering of the glass fiber balls in the mixing space 103 is reduced, and the uniformity of material distribution is improved.

[0048] In an embodiment of the present invention, there are multiple loading heads 220, which are spaced apart along the extension direction of the loading main pipe 210; there are multiple loading branch pipes 230, which are consistent with the number of loading heads 220 and are arranged one-to-one.

[0049] It should be noted that the feeding main pipe 210 extends in the transverse direction.

[0050] Specifically, there are multiple feeding heads 220, and the multiple feeding heads 220 are arranged at intervals along the extension direction of the feeding main pipe 210. The arrangement of the multiple feeding heads 220 ensures that the materials can be fully distributed before entering the mixing space 103, and prevents the problem of local concentration or uneven distribution caused by uneven supply of a single feeding head 220. Through this interval arrangement, the glass fiber balls can be evenly distributed to multiple areas along the entire length direction of the feeding main pipe 210, thereby improving the uniformity and efficiency of concrete mixing.

[0051] In addition, the number of feeding branches 230 provided is consistent with the number of feeding heads 220, and they are arranged one by one. This ensures that each feeding head 220 has an independent feeding channel, effectively avoiding the uneven feeding and mutual interference that may occur between different feeding heads 220 due to the shared feeding branch pipe 230. Each feeding branch pipe 230 enables each corresponding upper feeding head 220 to operate simultaneously to achieve synchronous feeding, thereby significantly improving the overall mixing efficiency. Therefore, the concrete distribution equipment can maintain good feeding stability and distribution uniformity under more complex material requirements, and is particularly suitable for concrete production environments with different mix ratio requirements. The provision of multiple feeding heads 220 and feeding branches 230 not only enhances the flexibility of the equipment, but also greatly improves the accuracy of material feeding and the mixing effect.

[0052] In the embodiment of the present invention, there are multiple quantitative bottles 300 , and the multiple quantitative bottles 300 are arranged at intervals along the extension direction of the feeding main pipe 210 .

[0053] Specifically, there are multiple quantitative bottles 300, and the multiple quantitative bottles 300 are arranged at intervals along the extension direction of the feeding main pipe 210. The arrangement of multiple quantitative bottles 300 allows the glass fiber balls to be simultaneously delivered from multiple independent quantitative bottles 300 to the mixing space 103 during the mixing process. It is ensured that each feeding head 220 and its corresponding mixing space 103 have an independent and accurate glass fiber ball supply source, avoiding the problem of insufficient supply caused by a single quantitative bottle 300.

[0054] More specifically, by evenly arranging a plurality of quantitative bottles 300 along the feeding main pipe 210, the concrete placing equipment can maintain the stability of material supply in a long-distance, multi-point working environment. The synchronous operation of the plurality of quantitative bottles 300 also improves the supply efficiency of the glass fiber balls and reduces the preparation and adjustment time required for each operation. Each quantitative bottle 300 can independently control the amount and rate of its feeding, so that the overall equipment has higher flexibility and can adapt to different production requirements and mixing ratios, especially under different process conditions, it can still effectively maintain the stability of product quality.

[0055] In the embodiment of the present invention, a plurality of quantitative bottles 300 and a plurality of feeding heads 220 are alternately arranged along the extending direction of the feeding main pipe 210 .

[0056] Specifically, a plurality of quantitative bottles 300 and feeding heads 220 are alternately arranged along the extension direction of the feeding main pipe 210. This can effectively optimize the conveying path and distribution of the glass fiber balls and achieve more uniform distribution of the glass fiber balls. This not only enhances the continuity and stability of the entire glass fiber ball feeding process, but also improves the overall mixing effect of the concrete.

[0057] More specifically, the quantitative bottle 300 is used to accurately control the supply amount of reinforcing materials such as glass fiber balls. By being arranged alternately with the feeding head 220, the glass fiber balls directly output by each quantitative bottle 300 can be quickly delivered to the adjacent feeding head 220, effectively shortening the feeding path, reducing the delivery time of the glass fiber balls, and preventing the glass fiber balls from settling or uneven mixing due to delay.

[0058] The feeding head 220 is responsible for introducing the material delivered from the quantitative bottle 300 into the mixing space 103. The alternating arrangement of multiple feeding heads 220 not only disperses the feeding pressure, but also makes the glass fiber balls in each area more concentrated and accurate, improving the overall mixing uniformity. It can not only improve production efficiency, but also reduce the complexity of operation, making the equipment more reliable and easy to maintain.

[0059] In the embodiment of the present invention, the size of the injection port 201 is gradually reduced from the loading head 220 toward the mixing space 103 .

[0060] Specifically, the size of the spray port 201 gradually decreases in the direction from the feed head 220 to the mixing space 103, and is arranged to be tapered. The glass fiber balls sprayed out can be accelerated, and by reducing the width or diameter of the discharge port, the glass fiber ball particles sprayed into the mixing space 103 have higher kinetic energy, thereby improving the dispersion ability of the glass fiber balls and ensuring that they are evenly distributed in the mixing space 103.

[0061] In addition, the tapered shape of the injection port 201 can prevent the glass fiber balls from aggregating or sagging due to gravity during the injection process to a certain extent, and promote better mixing of the glass fiber balls with other components in the mixing space 103. The ejected glass fiber ball flow is faster and denser, which reduces the wear rate and clogging risk of the inner wall of the injection head and the discharge port, and helps reduce the maintenance requirements of the injection head.

[0062] Please continue reading Figure 2 In an embodiment of the present invention, the quantitative bottle 300 includes a bottle body 310 and a top cover 320. The top cover 320 is detachably mounted on the top of the bottle body 310. An air inlet 301 is provided on the top cover 320. An air outlet 302 is provided at the bottom of the bottle body 310. The glass fiber ball is accommodated in the bottle body 310.

[0063] Specifically, the quantitative bottle 300 includes a bottle body 310 and a top cover 320. The top cover 320 is detachably mounted on the top of the bottle body 310, which is convenient for cleaning and maintenance of the quantitative bottle 300 and convenient loading of glass fiber balls. The top cover 320 is provided with an air inlet 301, which allows air to enter the bottle body 310 to balance the internal and external pressures, and prevent the material from flowing poorly due to the vacuum effect during the conveying process.

[0064] The bottom of the bottle 310 is provided with an air outlet 302 to ensure that the glass fiber balls can be smoothly discharged from the bottle 310 when needed. This helps to control the air pressure and airflow in the bottle, so that the glass fiber balls can be discharged at a balanced speed and stable flow rate to avoid material squeezing or jamming.

[0065] The glass fiber balls are contained in the bottle body 310 and kept in a sealed and dry environment, which reduces the risk of moisture and improves the storage life and reliability of the glass fiber balls. The quantitative bottle 300 of this embodiment can more accurately control the outflow of the material, which not only improves the uniformity and efficiency of feeding, but also ensures the quality stability of the glass fiber balls throughout the production process.

[0066] Please continue reading Figure 1 , and see Figure 3In an embodiment of the present invention, the premixing mechanism 400 includes a driving assembly 410 and a spiral stirring shaft 420. The driving assembly 410 forms a mounting portion, and the spiral stirring shaft 420 forms a rotating portion. The spiral stirring shaft 420 extends in the transverse direction, and one end of the spiral stirring shaft 420 is rotatably connected to the inner wall of the distribution hopper 100, and the other end of the spiral stirring shaft 420 is connected to the driving assembly 410. The driving assembly 410 is used to drive the spiral stirring shaft 420 to rotate in the mixing space 103 to mix concrete aggregate and glass fiber balls.

[0067] It should be noted that the driving assembly 410 is a motor in the prior art and is connected to the spiral stirring shaft 420 via a coupling.

[0068] Specifically, the premixing mechanism 400 includes a driving assembly 410 and a spiral stirring shaft 420. The driving assembly 410 provides a stable power source, which forms a mounting portion, and its function is to support and fix the entire premixing mechanism 400 to ensure the installation and operation stability of each component. The spiral stirring shaft 420 serves as a rotating portion and is responsible for the actual mixing of concrete materials.

[0069] The spiral stirring shaft 420 extends in the horizontal direction, and one end thereof is rotatably connected to the inner wall of the material distribution hopper 100, so that the spiral stirring shaft 420 obtains sufficient support and flexible rotation space in the material distribution hopper 100, ensuring that the shaft body of the entire spiral stirring shaft 420 can remain stable without deviation. The other end is connected to the driving assembly 410, so that the driving assembly 410 can directly transmit power to drive the rotation of the stirring shaft.

[0070] The driving assembly 410 is used to control the rotation of the spiral stirring shaft 420 in the mixing space 103. Through the rotation of the spiral stirring shaft 420, the concrete aggregate and the glass fiber balls can be fully stirred and mixed in the mixing space 103. The spiral stirring shaft 420 with a spiral structure helps to improve the mixing efficiency and ensure the uniformity of the mixing of various materials.

[0071] Please continue reading Figure 1 In the embodiment of the present invention, the distribution hopper 100 is covered with a grid plate 500 , and the grid plate 500 covers the feeding port 101 .

[0072] Specifically, a grid plate 500 is provided on the upper cover of the material distribution hopper 100. The grid plate 500 covers the feeding port 101 of the material distribution hopper 100, and its purpose is to preliminarily screen and intercept large pieces of materials or foreign objects before the concrete aggregate enters the material distribution hopper 100. The grid plate 500 can effectively filter out particles or objects exceeding a specified size, ensuring that the materials entering the material distribution hopper 100 are qualified materials suitable for further mixing and mixing. This not only helps to improve the uniformity of the final mixture, but also protects the normal operation of subsequent mixing and transmission equipment.

[0073] In the embodiment of the present invention, the size of the mixing space 103 is gradually reduced from the feeding port 101 toward the distribution port 102 .

[0074] Specifically, the size of the mixing space 103 is gradually reduced from the feeding port 101 to the distribution port 102, which can effectively guide the flow of materials from the feeding port 101 to the distribution port 102, and use gravity and the pressure naturally formed by the space reduction to push the materials into the distribution port 102 more quickly.

[0075] For the mixing process, the gradually shrinking space allows the material to be fully stirred in the entire mixing space 103, while also accelerating its movement toward the material distribution port 102. This reduces the retention time of the material in the mixing space 103 and reduces the stratification phenomenon that may occur due to stagnation.

[0076] In addition, the tapered mixing space 103 helps to improve the density and uniformity of the mixed materials. By controlling the flow path and speed difference and combining the stirring of the premixing mechanism 400, the mixing of concrete aggregate and glass fiber balls is made more uniform.
