Description

Technical Field

[0001] This utility model relates to the field of concrete pump technology, specifically a concrete pouring device. Background Technology

[0002] A concrete pump, also known as a concrete delivery pump, consists of a pump body and a delivery pipe. It is a machine that uses pressure to continuously transport concrete along a pipeline, and is mainly used in building construction, bridge construction, and tunnel construction.

[0003] For example, Chinese utility model patent CN221547216U proposes a concrete conveying pump for construction, including a pump body mechanism. A screening mechanism is fixedly connected to one side surface of the pump body mechanism, and reinforcing mechanisms are fixedly connected to the four corners of the lower surface of the pump body mechanism. A displacement mechanism is fixedly connected to one side surface of the lower end of the pump body mechanism near the center. The screening mechanism includes a screening shell, with a coarse screening bar snapped onto the upper surface of the screening shell. A fine screening bar is fixedly connected to one side surface of the coarse screening bar. The reinforcing mechanism includes a fixing block, and a second electric telescopic rod is fixedly connected to the upper surface inside the fixing block. In this utility model, the cooperation between the coarse and fine screening bars effectively solves the problem of not being able to use the pump due to large stones. Furthermore, the snap-fit ​​connection between the coarse and fine screening bars and the screening shell facilitates the maintenance of the coarse and fine screening bars.

[0004] However, in the existing equipment, the equal gaps between the screening bars cause problems when screening the aggregate in the concrete. Because the size and volume of the sand and gravel in the concrete are different, the requirements for the aggregate in the concrete are different when pouring the foundation and the wall. It is impossible to screen according to different requirements, and some relatively large stones cannot be screened, resulting in waste of stones. It cannot be adjusted according to needs, and its use is limited. Therefore, we propose a concrete pouring device. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a concrete pouring device with the advantage of adjustable screen gap, which solves the problem that the screen gap of existing devices is fixed, cannot be adjusted according to needs, and requires screen replacement, which is quite troublesome.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a concrete pouring device, comprising a main body, a discharge hopper at the top of the main body, a discharge pipe on one side of the discharge hopper, a feed funnel at the top of the discharge pipe, a stirring mechanism on one side of the feed funnel, a screening screen I on the inner wall of the feed funnel, a screening screen II at the bottom of the screening screen I, a long rod II inside the screening screen II, a screw penetrating one side of the screening screen I, multiple sliders I on the screw, a long rod on one side of each slider I, a handwheel on one side of the screw, and grooves I and II on both sides of the screening screen I, with a long rod embedded between the grooves I and II.

[0009] In some embodiments, the bottoms of the first slide and the second slide are inclined.

[0010] In some embodiments, a sliding rod is provided on the second sidewall of the slide groove, and a second slider is provided on one side of the long rod. The second slider is embedded in the second slide groove, and the sliding rod passes through the second slider.

[0011] In some embodiments, a spring is provided at the bottom of the screening screen, and a mounting block is provided at the bottom of the spring.

[0012] In some embodiments, the second slider is threadedly connected to the long rod, and the long rod is threadedly connected to the first slider.

[0013] In some embodiments, the second screening screen has an insertion hole at the top, and the first screening screen has a short rod at the bottom.

[0014] In some embodiments, the stirring mechanism includes a servo motor, a gear 1 is provided at one end of the output shaft of the servo motor, a gear 2 is meshed on one side of the gear 1, a rotating rod 2 is provided on one side of the gear 1, a rotating rod 1 is provided on one side of the gear 2, and stirring blades are provided on both the rotating rod 1 and the rotating rod 2.

[0015] In some embodiments, the second rotating rod is offset from the stirring blades provided on the first rotating rod.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a concrete pouring device, which has the following beneficial effects:

[0018] 1. This device uses a rotating screw to move a threaded slider, which in turn moves a long rod on one side. The long rod moves relative to the long rods inside the bottom screening mesh, thus blocking the gap between adjacent long rods and reducing their distance. This allows for the filtration of aggregates in concrete with different requirements.

[0019] 2. The device is driven by a servo motor to rotate a gear on one side. The rotation of gear one drives the rotation of gear two on the same side, which in turn causes the rotating rod two and rotating rod one on the same side of gear one and gear two to rotate. This causes the mixing blades on them to rotate and mix the concrete, preventing the accumulation of small stones inside. Attached Figure Description

Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0028] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0029] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0030] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0031] This application is described below with reference to the accompanying drawings and specific embodiments:

[0032] Combination Figures 1-6 This application provides a concrete pouring device, including a body 100. A discharge hopper 110 is provided at the top of the body 100. A discharge pipe 120 is provided on one side of the discharge hopper 110. A feed hopper 130 is provided at the top of the discharge pipe 120. A mixing mechanism 200 is provided on one side of the feed hopper 130. A screening screen 300 is provided on the inner wall of the feed hopper 130. A screening screen 310 is provided at the bottom of the screening screen 300. A long rod 370 is provided inside the screening screen 310. A screw 330 passes through one side of the screening screen 300. A plurality of sliders 350 are provided on the screw 330. A long rod 340 is provided on one side of the sliders 350. A handwheel 320 is provided on one side of the screw 330. A sliding groove 400 and a sliding groove 410 are opened on both sides of the screening screen 300. A long rod 340 is embedded between the sliding grooves 400 and the sliding grooves 410.

[0033] During operation, concrete is poured from the concrete mixer into the feed hopper 130. Screens 300 and 310 inside the feed hopper 130 filter the aggregate in the concrete, preventing excessively large stones from entering the discharge hopper 110. Before pouring the concrete, the handwheel 320 can be turned, driving the screw 330 to rotate. The rotation of the screw 330 moves a long rod 340 on one side, aligning it with the long rod 370 inside the bottom screen 300, thus adjusting the filter gap. This allows for filtering of aggregate according to different requirements. When pouring foundations, the gap is widened to allow large aggregate to enter; when pouring walls, the gap is narrowed. The filtered concrete enters the discharge hopper 110 and is then discharged through a pump inside the main body 100 via a discharge pipe 120 on one side of the discharge hopper 110, completing the pouring process within the required frame (the pump and mixer are existing technologies).

[0034] In some embodiments, the bottoms of slide 1 400 and slide 2 410 are inclined.

[0035] During use, chute 1 400 and chute 2 410 are inclined to prevent concrete from accumulating inside them.

[0036] In some embodiments, a slide bar 420 is provided on the side wall of the slide groove 410, and a slider 360 is provided on one side of the long rod 340. The slider 360 is embedded in the slide groove 410, and the slide bar 420 passes through the slider 360.

[0037] During use, when the screw 330 rotates and drives the slider 350 to move, the slider 350 drives the long rod 340 to move, and the long rod 340 drives the slider 360 set on one side to move. The slider 360 is embedded in the slide groove 410 and is penetrated by the slide rod 420, which facilitates the sliding of the slider 360 and limits its movement.

[0038] In some embodiments, a spring 600 is provided at the bottom of the screening screen 310, and a mounting block 610 is provided at the bottom of the spring 600.

[0039] During use, a spring 600 is installed at the bottom of the second screening screen 310. When concrete is poured into the feed funnel 130 and falls onto the surface of the first screening screen 300, the stones in the concrete impact the first screening screen 300, and the first screening screen 300 pushes the second screening screen 310 downward. The second screening screen 310 compresses the spring 600, which can buffer the first screening screen 300 and the second screening screen 310.

[0040] In some embodiments, slider 2 360 is threadedly connected to long rod 340, and long rod 340 is threadedly connected to slider 1 350.

[0041] After multiple uses, the rotating rod 340 can be separated from the second slider 360 and the first slider 350, making it easier to replace and clean the second slider 360.

[0042] In some embodiments, the second screening mesh 310 has an insertion hole 500 at the top and the first screening mesh 300 has a short rod 510 at the bottom.

[0043] During use, the first screening mesh 300 is inserted into the insertion hole 500 by the short rod 510 at the bottom to limit the movement of the second screening mesh 310. This prevents the first screening mesh 300 from shaking and misaligning with the second screening mesh 310 when concrete is poured onto its surface, which would cause changes in the filtration gap for the aggregate. After use, the first screening mesh and the second screening mesh 310 can be removed upwards for cleaning to prevent the concrete from solidifying on the surface.

[0044] In some embodiments, the stirring mechanism 200 includes a servo motor 210, a gear 240 is provided at one end of the output shaft of the servo motor 210, a gear 250 is meshed on one side of the gear 240, a rotating rod 230 is provided on one side of the gear 240, a rotating rod 220 is provided on one side of the gear 250, and stirring blades 260 are provided on both the rotating rod 220 and the rotating rod 230.

[0045] During use, when the servo motor 210 is turned on, the output shaft of the servo motor 210 drives the gear 1 240 to rotate. The gear 1 240 drives the gear 2 250 meshing on one side to rotate. The rotation of the gear 1 240 and the gear 2 250 drives the rotating rod 2 230 and the rotating rod 1 220 set on one side to rotate, so that the stirring blades 260 on the rotating rod 1 220 and the rotating rod 2 230 rotate to stir the concrete in the feed funnel 130.

[0046] In some embodiments, the second rotating rod 230 is staggered from the stirring blade 260 provided on the first rotating rod 220.

[0047] During use, the stirring blades 260 are staggered, so that when the stirring blades 260 on the rotating rod 230 and the rotating rod 220 are rotated and stirred, the stirring blades 260 on adjacent rods on the same rod can be stirred, making the stirring more uniform.

[0048] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. In addition, those skilled in the art can combine and integrate the different embodiments or examples described in this specification.

[0049] Furthermore, the technical solutions of the various embodiments can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed in this application.
