Description

Technical Field

[0001] The utility model belongs to the technical field of concrete feeding, in particular to a novel porous UHPC feeding hopper device. Background Art

[0002] UHPC (ultra-high performance concrete) is a concrete material with extremely high strength, durability, and toughness. Compared with traditional concrete, UHPC exhibits significant advantages in many aspects, especially in strength, wear resistance, impermeability, and freeze-thaw resistance. This has led to its widespread application in many engineering projects requiring high-performance materials. The compressive strength of UHPC can typically reach 150-200MPa or even higher, while the compressive strength of traditional concrete is usually between 20-50MPa. UHPC has an extremely low porosity, usually below 3%, while the porosity of ordinary concrete is generally 10% or higher.

[0003] However, the structure of some new UHPC hopper devices is relatively simple. Most of their structural designs are single-hole discharge, and materials are discharged through only one orifice. This can easily lead to concentrated accumulation or blockage of materials during the discharge process, and it is difficult to cast multiple samples at the same time, resulting in a slow rate and low efficiency in the production of casting molds. Utility Model Content

[0004] The purpose of the utility model is to provide a novel multi-porous UHPC discharge hopper device. By providing a discharge mechanism, multiple discharge ports and discharge pipes are set on the funnel, and the circulation mechanism is cooperated to flow the UHPC material so that the material flows out from the multiple discharge pipes evenly, which is convenient for the device to cast multiple molds at the same time and produce multiple samples synchronously, solving the problem of easy blockage and difficulty in casting multiple samples at the same time when discharging materials from one orifice, which is inefficient.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is a novel porous UHPC feeding hopper device, comprising a funnel, on which a feeding mechanism and a circulation mechanism are provided;

[0007] The discharge mechanism includes a porous component, a handle component, a locking component and a sealing component. The porous component includes several discharge ports opened on the inner wall of the funnel. The bottom surface of the funnel is fixedly connected to several discharge pipes. The inner walls of several of the discharge pipes are rotatably connected to sealing plates. The outer walls of several of the discharge pipes are fixedly connected to fixed blocks. The inner walls of several of the fixed blocks are rotatably connected to the first rotating shaft.

[0008] Furthermore, the sealing assembly includes handles fixedly connected to the right ends of the first rotating shafts, and the left ends of the first rotating shafts extend to the inner walls of the fixed blocks and are fixedly connected to the fixed blocks.

[0009] Furthermore, the locking assembly includes locking slots each opened on the right side of a plurality of fixed blocks, inner walls of a plurality of the first rotating shafts each open with a spring slot, and inner walls of a plurality of the spring slots each are fixedly connected with a spring.

[0010] Furthermore, the inner walls of several spring slots are slidably connected with a clamping block, the bottom surfaces of several clamping blocks are fixedly connected to the top ends of several springs, and the outer walls of several clamping blocks are slidably connected to the inner walls of the slots.

[0011] Furthermore, the circulation mechanism includes a spiral assembly and a bracket assembly, the spiral assembly includes two receiving blocks fixedly connected to the inner wall of the funnel, and the sides of the two receiving blocks close to each other are rotatably connected to a second rotating shaft.

[0012] Furthermore, a spiral blade is fixedly connected to the outer wall of the second rotating shaft, and the left end of the second rotating shaft extends to the outer wall of the funnel and is fixedly connected to a connector.

[0013] Furthermore, the bracket assembly includes two pads fixedly connected to the outer wall of the funnel, and the bottom surfaces of the two pads are fixedly connected to the support frame.

[0014] The utility model has the following beneficial effects:

[0015] 1. By setting up a feeding mechanism, multiple feeding ports and feeding pipes are set on the funnel. The UHPC material flows in conjunction with the circulation mechanism, so that the material flows out evenly from several feeding pipes, making it convenient for the device to cast multiple molds at the same time and produce multiple samples synchronously. Compared with single-hole feeding, multi-hole feeding can further improve the production efficiency of samples to a certain extent.

[0016] 2. By setting up a circulation mechanism, the staff can use an external drive device on the connecting head to drive the second rotating shaft to drive the spiral blade to rotate in the funnel, so that the UHPC material in the funnel can continuously flow along the thread in the funnel, reducing the undesirable phenomenon such as agglomeration of the UHPC material when it is left stationary. It can also cooperate with the discharge mechanism to further promote the uniform diversion and discharge of the UHPC material through several discharge pipes, thereby improving the practicality of the device.

[0017] Of course, it is not necessary to achieve all the advantages mentioned above at the same time when implementing any sample of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] See also Figure 1-5 As shown, the utility model is a novel porous UHPC feeding hopper device, comprising a hopper 1, on which a feeding mechanism 2 and a circulation mechanism 3 are provided;

[0028] The discharge mechanism 2 includes a porous component, a handle component, a locking component and a sealing component. The porous component includes several discharge ports 21 opened on the inner wall of the funnel 1. The bottom surface of the funnel 1 is fixedly connected to several discharge pipes 22. The inner walls of the several discharge pipes 22 are rotatably connected to sealing plates 23. The outer walls of the several discharge pipes 22 are fixedly connected to fixed blocks 24. The inner walls of the several fixed blocks 24 are rotatably connected to the first rotating shaft 25.

[0029] Among them Figure 3 、 Figure 4 and Figure 5 As shown, the locking assembly includes a plurality of slots 27 provided on the right side of the fixed blocks 24, the inner walls of the plurality of first rotating shafts 25 are provided with spring slots 28, the inner walls of the plurality of spring slots 28 are fixedly connected with springs 29, the inner walls of the plurality of spring slots 28 are slidably connected with a locking block 210, the bottom surfaces of the plurality of locking blocks 210 are fixedly connected with the top ends of the plurality of springs 29, and the outer walls of the plurality of locking blocks 210 are slidably connected with the inner walls of the slots 27.

[0030] By setting up the discharge mechanism 2, multiple discharge ports 21 and discharge pipes 22 are set on the funnel 1, and the circulation mechanism 3 is cooperated to flow the UHPC material, so that the material flows out from the multiple discharge pipes 22 evenly, which facilitates the device to cast multiple molds at the same time and produce multiple samples synchronously. Compared with single-hole discharge, multi-hole discharge can further improve the production efficiency of samples to a certain extent.

[0031] Among them Figure 2 and Figure 3 As shown, the circulation mechanism 3 includes a spiral component and a bracket component. The spiral component includes two receiving blocks 31 fixedly connected to the inner wall of the funnel 1. The two receiving blocks 31 are rotatably connected to the side close to each other with a second rotating shaft 32. The outer wall of the second rotating shaft 32 is fixedly connected to a spiral blade 33. The left end of the second rotating shaft 32 extends to the outer wall of the funnel 1 and is fixedly connected to a connecting head 34. The bracket assembly includes two pads 35 fixedly connected to the outer wall of the funnel 1. The bottom surfaces of the two pads 35 are fixedly connected to a support frame 36.

[0032] By providing the circulation mechanism 3, the staff can use the external driving device on the connecting head 34 to drive the second rotating shaft 32 to drive the spiral blade 33 to spirally rotate in the funnel 1, so that the UHPC material in the funnel 1 can continuously flow in the funnel 1 along the thread, reducing the undesirable phenomenon such as agglomeration of the UHPC material when it is left to stand. It can also cooperate with the discharge mechanism 2 to further promote the uniform diversion and outflow of the UHPC material through the multiple discharge pipes 22, thereby improving the practicality of the device.

[0033] A specific application of this embodiment is as follows: by setting up the blanking mechanism 2, the staff can manually pull the handle 26 to drive the first rotating shaft 25 to rotate, and the rotation of the first rotating shaft 25 drives the block 210 in the spring groove 28 to rotate, so that the block 210 stuck in the specific slot 27 is driven by the rotation force. The inclined surface of the block 210 contacts the inner wall inclined surface of the slot 27 to push the block 210 into the spring slot and slide toward the center, compressing the spring 29. The rotation of the first rotating shaft 25 drives the sealing piece 23 in the blanking tube 22 to rotate, and the sealing and blanking state of the blanking tube 22 is manually adjusted, which is convenient for real-time operation of the blanking situation between several blanking tubes 22. After completing the adjustment of the sealing piece 23, the elastic action of the spring 29 drives the block 210 to rebound and be stuck in the specific slot 27. In the groove, the elastic resistance of the spring 29 is used to limit the rotation of the sealing piece 23, thereby reducing special circumstances or the situation where the sealing piece 23 accidentally flips over and leaks materials due to excessive concrete material in the discharge pipe 22, and enhances the torque force of the first rotating shaft 25. The spiral blade 33 is rotated in conjunction with the circulation mechanism 3 to allow the concrete material in the funnel 1 to enter the discharge pipe 22 through the discharge port 21, and flow out from several discharge pipes 22 and be evenly cast in the mold, thereby realizing the arrangement of multiple discharge ports 21 and discharge pipes 22 on the funnel 1, and cooperating with the circulation mechanism 3 to flow the UHPC material, so that the material flows out evenly from several discharge pipes 22, which facilitates the device to cast multiple molds at the same time and produce multiple samples synchronously. Compared with single-hole discharge, multi-hole discharge can further improve the production efficiency of samples to a certain extent.

[0034] By setting up the circulation mechanism 3, the staff can fix the motor to the connector 34 so that the external motor equipment drives the second rotating shaft 32 to rotate through the connector 34, and the second rotating shaft 32 drives the spiral blade 33 to rotate in the funnel 1, so as to spirally stir the UHPC material in the funnel 1, so that it is in a flowing state in the funnel 1, and avoid the situation where the UHPC material is stationary for a long time and agglomerates. Two receiving blocks 31 are provided to support and limit the rotation of the second rotating shaft 32 in the funnel 1, and a pad 35 is provided to receive the unloading mechanism 2 and The support frame 36 is connected to the funnel 1, and the support frame 36 supports and fixes the funnel 1, ensuring the smooth discharge of the funnel 1. The staff can use the external driving device on the connecting head 34 to drive the second rotating shaft 32 to drive the spiral blade 33 to spirally rotate in the funnel 1, so that the UHPC material in the funnel 1 continuously flows along the thread in the funnel 1, reducing the undesirable phenomena such as agglomeration of the UHPC material when it is left to stand. It can also cooperate with the discharge mechanism 2 to further promote the uniform diversion and outflow of the UHPC material through the multiple discharge pipes 22, thereby improving the practicality of the device.
