Description

Technical Field

[0001] This invention relates to the field of conveying device technology, and specifically to a material conveying device for construction engineering. Background Technology

[0002] In the conveying devices for construction materials, there are devices that use compressed air as a power source for long-distance and high vertical conveying of concrete mixtures. These devices transport construction materials to designated locations through sealed pipelines and have the advantages of being pollution-free, having flexible layouts, and being suitable for complex construction sites.

[0003] In actual use, existing pneumatic conveying devices can cause gas oscillations in the conveying pipeline when high-pressure gas is first injected into it, which may lead to backflow of the concrete mixture and thus affect the conveying of the concrete mixture. On the other hand, the concrete mixture inlet and rotary valve cannot be completely sealed, resulting in some high-pressure gas leakage into the feeding system, which also affects the feeding of the concrete mixture. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a material conveying device for construction projects to solve the problems of the prior art.

[0005] This invention is achieved through the following technical solution:

[0006] A construction material conveying device includes a conveying pipe, a material distribution structure installed on the conveying pipe, a feeding structure installed on the material distribution structure, a symmetrically distributed circulation structure installed inside the material distribution structure, and an agitation structure installed inside the feeding structure.

[0007] The material distribution structure includes a connecting pipe installed on the conveying pipe, a threaded rotary valve rotatably connected inside the connecting pipe, and an array of extrusion inlets opened on the connecting pipe. The feeding structure includes a shell installed on the outer contour of the material distribution structure, a partition block installed inside the shell, and an extrusion plate slidably connected inside the partition block.

[0008] The connecting pipe has symmetrically distributed flow ports. The agitation structure includes a piston chamber installed on the feeding structure. A compression piston is slidably connected inside the piston chamber. The lower side of the piston chamber is connected to the flow ports.

[0009] Preferably, symmetrically distributed isolation rings are installed inside the connecting pipe, and the heights of the threaded blades of the threaded rotary valve are staggered.

[0010] Preferably, the outer shell is equipped with a feed inlet, and the partition block is provided with symmetrically distributed sliding grooves.

[0011] Preferably, a partition plate is installed inside the partition block, the partition plate has an inclined groove, a bottom plate is installed on one side of the partition plate, and an extension plate is installed on the side of the extrusion plate near the partition plate, the extension plate and the partition plate are slidably engaged.

[0012] Preferably, the extrusion plate and the partition block are extruded together, the lower side of the extrusion plate is in contact with the upper side of the connecting pipe, and the extrusion plate and the connecting pipe are extruded together.

[0013] Preferably, the circulation structure includes symmetrically distributed rotating disks mounted on a threaded rotary valve. The rotating disks are rotatably engaged with the connecting pipe and the isolation ring, respectively. Each rotating disk has a circulation groove, and a transmission rod is slidably connected in the circulation groove.

[0014] Preferably, a sliding frame is rotatably connected to the transmission rod, the sliding frame is slidably engaged with the rotating disk, a connecting frame is installed inside the sliding frame, the connecting frame is slidably engaged with the separator block, and the lower end of the connecting frame is installed on the upper side of the extrusion plate.

[0015] Preferably, a horizontal plate is slidably connected to the base plate, an agitator is rotatably connected to the horizontal plate, a vertical plate is rotatably connected to the other side of the agitator, and the vertical plate is fixedly connected to the extrusion piston.

[0016] Preferably, symmetrically distributed sliding rods are installed on the horizontal plate, and limit rods are slidably connected to the sliding rods. A return spring is provided around the sliding rods between the sliding rods and the limit rods.

[0017] Preferably, the limiting rod is installed on the inner wall of the housing, and a limiting ring is provided on the lower side of the piston chamber.

[0018] The beneficial effects of this invention are as follows:

[0019] This construction material conveying device utilizes an array of extrusion inlets on a connecting pipe, along with sliding extrusion plates. Concrete mix is ​​extruded through these inlets into the connecting pipe via the extrusion plates, eliminating wear between the concrete mix and the threaded rotary valve compared to existing feeding methods. The threaded rotary valve is driven entirely by high-pressure gas injected into the conveying pipe, which, in conjunction with a circulation structure, causes the extrusion plates to slide up and down, achieving automatic feeding. This avoids vibrations in the high-pressure gas within the conveying pipe, which could affect the conveying pipe and feeding device, thus impacting the concrete mix feeding. The staggered threaded blades on the threaded rotary valve limit the range of high-pressure gas agitation, controlling its rotational speed and thus the feeding effect. A flow port on the connecting pipe exchanges the high-pressure gas within the gaps of the threaded rotary valve's helical blades, allowing leaked gas from the conveying pipe to enter between the connecting pipe and the outer casing, pushing the extrusion piston upwards to agitate the concrete mix on the base plate.

All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0038] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0039] In the above description of the present invention, it should be noted that the terms "one side," "the other side," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the invention is conventionally placed during use. These terms are used only for the convenience of describing the present invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0040] Furthermore, terms such as "identical" do not imply that components must be absolutely identical; minor differences are permissible. The term "perpendicular" simply means that the positional relationship between components is more perpendicular than "parallel," not that the structure must be perfectly perpendicular; a slight tilt is acceptable.

[0041] This invention provides a technical solution:

[0042] Please see Figures 1 to 10 A material conveying device for construction engineering. It includes a conveying pipe 1, a material distribution structure 2 installed on the conveying pipe 1, a feeding structure 3 installed on the material distribution structure 2, a symmetrically distributed circulation structure 4 installed inside the material distribution structure 2, and an agitation structure 5 installed inside the feeding structure 3;

[0043] The material distribution structure 2 includes a connecting pipe 21 installed on the conveying pipe 1, a threaded rotary valve 22 rotatably connected inside the connecting pipe 21, and an array of extrusion inlets 23 opened on the connecting pipe 21. The feeding structure 3 includes a housing 31 installed on the outer contour of the material distribution structure 2, a partition block 33 installed inside the housing 31, and an extrusion plate 35 slidably connected inside the partition block 33.

[0044] The connecting pipe 21 has symmetrically distributed flow ports 24. The agitation structure 5 includes a piston chamber 57 installed on the feeding structure 3. A compression piston 58 is slidably connected inside the piston chamber 57. The lower side of the piston chamber 57 is connected to the flow port 24.

[0045] The above method is adopted: by continuously injecting high-pressure gas into the conveying pipe 1, the threaded rotary valve 22 is continuously rotated. During the rotation of the threaded rotary valve 22, the concrete mixture squeezed into the connecting pipe 21 through the extrusion inlet 23 is scraped off by the threaded blades on the threaded rotary valve 22 and falls between the threaded blades of the threaded rotary valve 22 until it falls into the conveying pipe 1 as the threaded rotary valve 22 rotates, so as to achieve the effect of automatic feeding. This avoids the disorderly rotation of the threaded rotary valve 22 caused by the vibration of high-pressure gas, which would affect the feeding of concrete mixture.

[0046] By sliding the extrusion plate 35 up and down, the extrusion plate 35 squeezes the concrete mixture outside the connecting pipe 21 into the connecting pipe 21 through the extrusion inlet 23. Since the up and down sliding of the extrusion plate 35 is linked with the rotation of the threaded rotary valve 22, the concrete mixture entering the threaded rotary valve 22 is quantitatively controlled.

[0047] The rotation of the threaded rotary valve 22 causes the high-pressure gas in the gap of the threaded rotary valve 22 to enter the space between the connecting pipe 21 and the outer shell 31 through the flow port 24. This causes the extrusion piston 58 in the piston chamber 57 to be extruded and slide upward, which in turn drives the agitation structure 5 to slide upward. This causes the small amount of leaked high-pressure gas to enter the space between the connecting pipe 21 and the outer shell 31, push the extrusion piston 58, and then return. After the threaded rotary valve 22 passes through the flow port 24, the gas in the threaded rotary valve 22 cannot leak upward due to the concrete mixture filling the extrusion port 23, and thus returns to the delivery pipe 1.

[0048] Please see Figure 2 The connecting pipe 21 is equipped with symmetrically distributed isolation rings 25, and the heights of the threaded blades of the threaded rotary valve 22 are staggered.

[0049] The above method is adopted: by setting the threaded blades of the threaded rotary valve 22 to be staggered in height, after the concrete mixture is squeezed into the gap of the threaded rotary valve 22, the high threaded blades of the threaded rotary valve 22 scrape off the concrete mixture on the inner wall of the connecting pipe 21. During the rotation of the threaded rotary valve 22, the rotation speed of the threaded rotary valve 22 is limited by the staggered distribution of the threaded blades.

[0050] Please see Figures 3 to 5 The outer casing 31 is equipped with a feed inlet 32, and the partition block 33 is provided with symmetrically distributed sliding grooves 34.

[0051] A partition plate 37 is installed inside the partition block 33. An inclined groove 39 is opened inside the partition plate 37. A bottom plate 38 is installed on one side of the partition plate 37. An extension plate 36 is installed on the side of the extrusion plate 35 near the partition plate 37. The extension plate 36 and the partition plate 37 are in sliding fit.

[0052] The extrusion plate 35 and the partition block 33 are extruded together, and the lower side of the extrusion plate 35 is in contact with the upper side of the connecting pipe 21. The extrusion plate 35 and the connecting pipe 21 are extruded together.

[0053] Using the above method: the concrete mixture is injected into the outer shell 31 through the feed port 32 and then falls onto the bottom plate 38. It enters the connecting pipe 21 through the inclined groove 39 on the partition plate 37. As the extrusion plate 35 slides up and down, the concrete mixture is intermittently controlled to enter the connecting pipe 21. The extension plate 36 on the extrusion plate 35 restricts the concrete mixture from being fed through the inclined groove 39 during the downward sliding of the extrusion plate 35.

[0054] Please see Figure 6 and Figure 7 The circulation structure 4 includes symmetrically distributed rotating disks 41 mounted on the threaded rotary valve 22. The rotating disks 41 are rotatably engaged with the connecting pipe 21 and the isolation ring 25 respectively. Each rotating disk 41 is provided with a circulation groove 45, and a transmission rod 42 is slidably connected in the circulation groove 45.

[0055] A sliding frame 43 is rotatably connected to the transmission rod 42. The sliding frame 43 is in sliding engagement with the rotating disk 41. A connecting frame 44 is installed inside the sliding frame 43. The connecting frame 44 is in sliding engagement with the partition block 33. The lower end of the connecting frame 44 is installed on the upper side of the extrusion plate 35.

[0056] Using the above method: the circulation groove 45 opened on the rotating disk 41 allows the transmission rod 42 to slide within the circulation groove 45 as the rotating disk 41 rotates with the threaded rotary valve 22, thereby causing the sliding frame 43 and the connecting frame 44 to slide up and down. Since the connecting frame 44 is installed on the extrusion plate 35, it drives the extrusion plate 35 to slide synchronously. The protrusions set on the upper and lower positions of the connecting frame 44 by the sliding frame 43 ensure the sealing effect within the partition block 33 during the sliding of the connecting frame 44 within the sliding groove 34.

[0057] Please see Figures 8 to 10 A horizontal plate 51 is slidably connected to the base plate 38, and an agitator 52 is rotatably connected to the horizontal plate 51. A vertical plate 53 is rotatably connected to the other side of the agitator 52, and the vertical plate 53 is fixedly connected to the extrusion piston 58.

[0058] A symmetrically distributed sliding rod 54 is installed on the horizontal plate 51. A limit rod 55 is slidably connected to the sliding rod 54. A return spring 56 is arranged around the sliding rod 54 between the sliding rod 54 and the limit rod 55.

[0059] The limiting rod 55 is installed on the inner wall of the housing 31, and a limiting ring is provided on the lower side of the piston chamber 57.

[0060] Using the above method: by squeezing the piston 58 to slide upward, the vertical plate 53 is driven to slide upward synchronously, which in turn drives the horizontal plate 51 to slide towards the inner wall of the outer shell 31, so that the stirring plate 52 changes from a horizontal state to an inclined state, thereby achieving the effect of stirring the concrete mixture on the bottom plate 38.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
