Description

Technical Field

[0001] The invention relates to the technical field of prefabricated plate processing, and particularly discloses a prefabricated plate casting device. Background Art

[0002] Precast panels are building wall panels produced in a standardized, mechanized factory process. During the precast panel production process, mixed concrete is poured into molds and then allowed to solidify. Currently, most precast components are cast manually, where workers pour concrete into molds using containers, then use scrapers or other tools to level the concrete. After leveling, high-frequency vibrations are applied to the molds to achieve self-compacting concrete. This traditional manual casting method is not only labor-intensive but also inefficient, severely limiting the efficient production of precast panels.

[0003] The utility model patent application number 202121161847X discloses a precast slab concrete pouring device, comprising a concrete container, a support frame for supporting the concrete container, a movable slide rail for facilitating the movement of the concrete pouring device, a plurality of precast slab support platforms arranged on both sides of the movable slide rail for placing molds, and a concrete conveying device arranged directly below the concrete container for conveying concrete into the mold. During the precast slab concrete pouring process, the precast slab concrete pouring device moves the support frame along the movable slide rail to the corresponding precast slab support platform, and then uses the concrete conveying device to pour the concrete discharged from the concrete container into the mold on the precast slab support platform. Compared with the existing manual concrete pouring method, the precast slab concrete pouring device reduces the labor intensity of the operator and improves the work efficiency. However, the precast slab concrete pouring device can only pour concrete into the mold at a fixed point. Since the area of ​​a typical precast slab is large, after the concrete is poured into the mold, it needs to be manually leveled. During the manual leveling process, it is easily obstructed by the steel frame in the mold, making the entire operation process more complicated. Therefore, in response to the above-mentioned deficiencies of the existing precast slab concrete pouring device, the present application proposes a precast slab pouring device that can effectively solve the above-mentioned technical problems. Summary of the Invention

[0004] The present invention aims to provide a precast slab casting device to solve the disadvantages of existing precast slab concrete casting devices that can only discharge materials at fixed points, resulting in the need for manual leveling after the precast slab is poured and discharged.

[0005] The present invention is achieved through the following technical solutions:

[0006] The conveyor belt conveyor is provided with a plurality of guide rails at the bottom end thereof, and a plurality of guide rails are provided at the bottom end thereof.

[0007] As a further arrangement of the above scheme, a rotating connecting pipe is provided at the lower end of the longitudinal feeding cylinder, and the discharge swing pipe includes a horizontal pipe, and the two ends of the horizontal pipe are respectively provided with a first pipe end pointing vertically upward and a second pipe end pointing vertically downward, and the first pipe end is provided with a bearing connected to the rotating connecting pipe.

[0008] As a further arrangement of the above scheme, the second pipe end is connected to a deflector cover by rotation, the deflector cover is provided with a gear ring, the outer surface of the second pipe end is provided with an adjusting motor, and the motor shaft of the adjusting motor is provided with a gear meshing with the gear ring.

[0009] As a further configuration of the above solution, the upper end of the air guide cover is cylindrical, the left and right sides of the lower end of the air guide cover extend outward, and the front and rear sides converge and contract toward the middle to form a straight-line discharge port.

[0010] As a further configuration of the above solution, a roller seat is fixed on the side of the concrete silo, and a row of running wheels moving along the track frame is provided in the roller seat. The track frame is also provided with a traction device for realizing the movement of the concrete silo.

[0011] As a further arrangement of the above scheme, a guide block is provided at the lower end of the inner wall of the concrete silo near one side of the longitudinal feed cylinder, and a mixing bottom chamber is formed between the guide block and the other side wall of the concrete silo. A semicircular groove is provided on the guide block and is aligned front and back with each longitudinal feed cylinder, and the spiral blade is provided on the drive shaft in the longitudinal feed cylinder and the semicircular groove.

[0012] As a further configuration of the above solution, a stirring frame is provided on the driving shaft located in the stirring bottom chamber, and the stirring frames on two adjacent driving shafts are staggered.

[0013] As a further configuration of the above solution, slide rails are provided on the lower surfaces of the concrete silo on the left and right sides of the telescopic pusher, and the adjustment plate is slidably arranged on the two slide rails.

[0014] As a further configuration of the above solution, a cleaning port is provided at the lower end of the side surface of the concrete silo, and a sealing plate is detachably provided on the cleaning port.

[0015] During use of the precast slab casting device disclosed in the present invention, the concrete silo is moved along the track frame by a traction device. Then, when the concrete silo is moved above the precast slab mold, the corresponding unloading motor is controlled to operate according to the required pouring width of the precast slab. Then, through the action of the unloading motor, the drive shaft, and the spiral blades, concrete can be unloaded from multiple points, so that the poured concrete material evenly and comprehensively covers the precast slab mold.

[0016] The precast panel casting device also controls the extension or contraction of the telescopic drive member according to the effective width of the precast panel. The telescopic drive member then moves the adjustment plate along the slide rail. During this movement, the guide slides and corresponding guide slots interact to adjust the front end spacing of all the discharge sway pipes to match the effective width of the precast panel mold, significantly expanding the applicability of the entire precast panel casting device.

[0017] In addition, this precast slab casting device is equipped with a specially designed deflector cover at the front end of the discharge swing pipe, and then controls the effective width of the straight-line discharge port at the lower end of the deflector cover by precisely controlling the rotation angle of the motor, so that the concrete material discharged from all the deflectors can be laid more evenly in the precast slab mold. After the concrete pouring is completed, there is no need for manual leveling, and vibration compaction can be directly performed.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The precast slab casting device disclosed in the present invention can independently control whether the corresponding unloading motor is running according to the effective width of the precast slab during discharge, thereby achieving the effect of uniform unloading at multiple points; in addition, when the effective width of the precast slab is large, the movement of the adjustment plate can be achieved by a telescopic drive member, and then the unloading swing pipe is rotated through the action between the guide slide groove and the guide slide column, thereby adjusting the spacing of the outer ends of the unloading swing pipe, so that it is adapted to the effective width of the precast slab mold and then unloading is carried out at multiple points at the same time, ensuring that concrete can be evenly poured in the precast slab mold, effectively improving the applicability of the entire device.

[0020] The present invention further has a guide hood with a straight discharge port rotatably connected to the discharge end of the discharge swing pipe. At the same time, a driving component for accurately rotating and adjusting the guide hood is provided on the discharge swing pipe. After the discharge end of the discharge swing pipe is opened, the angle of the guide hood can be controlled to make the concrete material more evenly laid in the precast plate mold. After pouring is completed, there is no need for leveling, which greatly improves the efficiency of precast plate pouring. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, a traction device (not shown in the figure) for driving the concrete bin 2 to move along the track 1 is arranged on the track 1. The specific traction device can use an electric hoist as a tractor.

[0031] Referring to the attached Figure 3 and the attached Figure 4 A row of equally spaced longitudinal feeding tubes 5 is arranged on the front side of the lower end of the concrete bin 2, and a flow guide block 6 is arranged on the inner wall of the concrete bin 2 near the side of the longitudinal feeding tube 5, and the flow guide block 6 and the other side wall of the concrete bin 2 form a stirring bottom cavity, and a semicircular groove 601 is formed on the flow guide block 6, which is aligned with each longitudinal feeding tube 5 in front and back. A drive shaft 7 is rotatably connected in each longitudinal feeding tube 5, and a discharging motor 8 is arranged on the rear side of the concrete bin 2, which is aligned with each drive shaft 7 in front and back. The specific discharging motor 8 is a variable frequency motor, and a control box 9 is arranged on the rear side of the concrete bin 2, and the control box 9 is provided with a corresponding variable frequency module inside, so that each discharging motor 8 can be controlled by the control box 9 to operate. The rear end of the drive shaft 7 is connected to the corresponding discharging motor 8, so that the drive shaft 7 can rotate at a set speed under the action of the discharging motor 8. A screw blade 10 is arranged on the drive shaft 7 in the longitudinal feeding tube 5 and the semicircular groove 601, and a stirring frame 11 is arranged on the drive shaft 7 in the stirring bottom cavity, and the stirring frames 11 on adjacent two drive shafts 7 are arranged in front and back staggered, to prevent the two stirring frames 11 from colliding during the rotation of the drive shaft 7.

[0032] Referring to the attached Figure 6The lower end of each longitudinal feed tube 5 is connected to a rotating connecting pipe 501, and then the lower end of the rotating connecting pipe 501 is rotatably connected to a feed oscillating pipe 12. In the specific design, the feed oscillating pipe 12 includes a horizontal tube 121, with a first tube end 122 pointing vertically upward and a second tube end 123 pointing vertically downward connected at both ends of the horizontal tube 121.

In addition, a guide slide 125 is provided on the lower surface of the horizontal tube 121, and the guide slide 125 is made of a wear-resistant metal material.

[0033] Reference Attachment Figure 4 A telescopic pusher 13 is fixedly mounted on the lower surface of the concrete silo 2. The specific telescopic pusher can be a pneumatic cylinder, electric push rod, or screw lift. Slide rails 14 are fixed to the lower surface of the concrete silo 2 on both sides of the telescopic pusher 13. An adjustment plate 15 slides between the two slide rails 14, connecting the ends of the telescopic pusher 13 to the adjustment plate 15. The adjustment plate 15 is provided with guide slots 151 that match the guide posts 125 on each feeder tube 12. Multiple guide slots 151 extend radially forward. When the guide posts 125 on the feeder tube 12 are located at the end of the guide slots 151 near the telescopic pusher 13, all feeder tubes 12 are arranged parallel and forward. When the guide posts 125 on the feeder tube 12 are located at the end of the guide slots 151 away from the telescopic pusher 13, the front ends of all feeder tubes 12 extend radially outward.

[0034] During the pouring process of the precast slab mold, the precast slab casting device disclosed in Example 1 first loads the mixed concrete into the concrete hopper 2. The telescopic pusher 13 is then extended or shortened according to the effective width of the precast slab mold, thereby moving the adjustment plate 15 along the slide rail 14. During the movement of the adjustment plate 15, the interaction between the guide slide 125 and the corresponding guide chute 151 adjusts the front end spacing of all the discharge spools 12 to match the effective width of the precast slab mold.

The left and right sides of the lower end of the deflector 16 extend outward, while the front and rear sides converge toward the center, forming a straight-line discharge opening at the lower end of the deflector 16, which increases the effective width for concrete discharge.

[0037] In addition, in order to adjust the effective width of the air guide hood 16 when unloading according to the adjustment state of the unloading swing pipe 12, a ring gear 17 is provided on the outer surface of the upper end of the air guide hood 16, and then an adjustment motor 18 is fixedly provided at the upper end of the second pipe end 123. The adjustment motor 18 can specifically be a stepper motor, and a gear 19 meshing with the ring gear 17 is provided on the motor shaft of the adjustment motor 18.
