Description

Technical Field

[0001] This utility model relates to the field of concrete production technology, specifically to a concrete feeding hopper. Background Technology

[0002] During the construction process, a large amount of concrete is required for pouring. Therefore, when injecting concrete into the building, a hopper is needed to guide the concrete and ensure that it is accurately poured into the building's pouring hole.

[0003] For example, Chinese patent CN212927061U discloses a concrete hopper, including a hopper, a support frame, a hopper opening closure device, and a lever mechanism. The hopper is fixedly mounted on the support frame in a vertical direction. The bottom of the hopper has a hopper opening. The hopper opening closure device is movably mounted on the hopper and can close or open the hopper opening by moving it. The lever mechanism is mounted on the support frame and is connected to the hopper opening closure device, thereby driving the hopper opening closure device to open or close. This utility model provides a concrete hopper that can realize the closing and opening of the hopper opening. This concrete hopper has good flexibility, reduces labor intensity and cost, improves construction efficiency, and increases construction benefits.

[0004] However, the above solution still has some problems when used. During the production of concrete, large aggregate particles are inevitably mixed in. However, the concrete hopper does not take into account the problem of large aggregate particles. When there are too many large aggregate particles in each hopper, it will cause the hopper to become blocked. Therefore, it is proposed to use a concrete hopper to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a concrete feeding hopper that has the advantage of filtration and solves the problem of large aggregate particles clogging the hopper.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a concrete feeding hopper, comprising a hopper, a support assembly fixed to the outer surface of the hopper, a connecting plate fixed to the inside of the hopper, a filter mechanism penetrating into the inside of the hopper provided on the back of the hopper, a discharge port fixed to the bottom of the hopper, and a guide plate fixed to the back of the discharge port. The filtration mechanism includes a protective chamber, a drive assembly, an eccentric wheel, a movable frame, two movable plates, a filter assembly, and two stabilizing assemblies. The protective chamber is fixed to the rear wall of the hopper cavity. The drive assembly is located on the back of the hopper and extends through the interior of the protective chamber. The eccentric wheel is fixed to the outer surface of the drive assembly. The movable frame contacts the outer surface of the eccentric wheel. The two movable plates are fixed to the left and right sides of the movable frame, respectively. The filter assembly is fixed to the front of the movable plate and extends through the front of the protective chamber. The two stabilizing assemblies are located on the back of the two movable plates and are fixed to the rear wall of the hopper cavity.

[0007] By adopting this technical solution, concrete is poured into the hopper and falls onto the filtration mechanism. The filtration mechanism can then screen large aggregate particles in the concrete and discharge the filtered concrete from the outlet. The guide plate then guides the concrete to flow steadily into the pouring hole.

[0008] Furthermore, the drive assembly includes a drive chamber, a motor, and a rotating rod. The drive chamber is fixed to the back of the hopper, the motor is fixed to the rear side wall of the drive chamber cavity, the rotating rod is fixed to the output shaft of the motor, and the rotating rod extends into the interior of the protective chamber and is fixed to the interior of the eccentric wheel.

[0009] By adopting this technical solution, the operation of the motor enables the rotating rod to rotate, which in turn drives the eccentric wheel to rotate. The eccentric wheel, through the action of the moving frame and the moving plate, drives the filter assembly to operate.

[0010] Furthermore, the filter assembly includes two connecting rods, a protective plate, and a filter plate. The two connecting rods are respectively fixed to the front of the two movable plates. The protective plate is fixed to the front of the connecting rods and is slidably connected to the top of the connecting plate. The filter plate is fixed to the inside of the protective plate.

[0011] By adopting this technical solution, when concrete falls into the filter assembly, the filter assembly can move back and forth by driving the operation of the assembly, thereby enabling the filter plate to filter the concrete.

[0012] Furthermore, the protective compartment has a movable hole on the front for the connecting rod to move, and a flexible plate fixed inside the movable hole is fixed to the outer surface of the connecting rod.

[0013] By adopting this technical solution and setting up flexible plates, concrete can be prevented from flowing into the interior of the protective chamber through the moving holes, thus preventing concrete from accumulating inside the protective chamber and making the operation of the filtration mechanism more stable.

[0014] Furthermore, the stabilizing component consists of two sliders and a slide rail. The two sliders are respectively fixed to the back of the two moving plates, and the slide rail is slidably connected to the inside of the sliders and fixed to the rear side wall of the hopper cavity.

[0015] By adopting this technical solution, the sliding frame and two moving plates can be supported through the setting of sliders and slide rails, and the movement of the moving plates can be smoother, thereby improving the stability of the moving plates during operation.

[0016] Furthermore, the connecting plate has through holes, and the bottom of the protective plate is fixed with two positioning blocks.

[0017] By adopting this technical solution, the through holes allow the filtered concrete to fall through the holes to the discharge port.

[0018] Furthermore, the positioning block is inverted T-shaped, and the top of the connecting plate is provided with a positioning groove that matches the positioning block.

[0019] By adopting this technical solution, the filtration mechanism can be supported by the positioning block and positioning groove, and the movement of the filtration mechanism can be made more stable.

[0020] Furthermore, the top of the hopper is open, and the support assembly consists of a mounting plate and four support legs. The mounting plate is fixed to the outer surface of the hopper, and the four support legs are all fixed to the bottom of the mounting plate.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects: 1. The concrete is fed into a hopper, allowing it to fall onto the filtration mechanism. The filtration mechanism is then activated to filter out large aggregate particles in the concrete, thus preventing clogging of the hopper.

[0022] 2. The concrete uses a hopper. After the concrete is filtered, it falls onto the guide plate through the discharge port. The guide plate helps the concrete to enter the pouring hole stably, thereby improving the stability of the concrete discharge and reducing concrete spillage. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 The concrete hopper in this embodiment includes a hopper 1 with an open top. A support assembly 2 is fixed to the outer surface of the hopper 1. The support assembly 2 consists of an mounting plate and four support legs. The mounting plate is fixed to the outer surface of the hopper 1, and the four support legs are fixed to the bottom of the mounting plate. A connecting plate 3 is fixed inside the hopper 1. A through hole is provided on the connecting plate 3. The concrete filtered by the filtering mechanism 4 can fall through the through hole to the discharge port 5. A filtering mechanism 4 penetrating into the interior of the hopper 1 is provided on the back of the hopper 1. A discharge port 5 is fixed to the bottom of the hopper 1, and a guide plate 6 is fixed to the back of the discharge port 5.

[0027] It should be noted that when concrete is poured into the hopper 1, it falls onto the filter mechanism 4. Through the operation of the filter mechanism 4, large aggregate particles in the concrete can be screened, and the filtered concrete is discharged from the outlet 5. Then, through the action of the guide plate 6, the concrete can flow steadily into the pouring hole.

[0028] Please see Figure 2-3In order to filter large aggregate particles, the filtering mechanism 4 in this embodiment includes a protective chamber 401, a driving assembly, an eccentric wheel 405, a moving frame 406, two moving plates 407, a filtering assembly, and two stabilizing assemblies. The driving assembly includes a driving chamber 402, a motor 403, and a rotating rod 404. The driving chamber 402 is fixed to the back of the hopper 1, the motor 403 is fixed to the rear side wall of the inner cavity of the driving chamber 402, and the rotating rod 404 is fixed to the output shaft of the motor 403. The rotating rod 404 extends into the interior of the protective chamber 401 and is fixed to the interior of the eccentric wheel 405. The operation of the motor 403 causes the rotating rod 404 to rotate, thereby driving the eccentric wheel 405 to rotate. The eccentric wheel 405, through the action of the moving frame 406 and the moving plate 407, drives the filtering assembly to operate.

[0029] The protective chamber 401 is fixed to the rear wall of the inner cavity of the hopper 1. The drive assembly is located on the back of the hopper 1 and extends through the interior of the protective chamber 401. The eccentric wheel 405 is fixed to the outer surface of the drive assembly. The moving frame 406 contacts the outer surface of the eccentric wheel 405. Two moving plates 407 are fixed to the left and right sides of the moving frame 406 respectively. The filter assembly is fixed to the front of the moving plate 407, and the drive assembly extends through the front of the protective chamber 401. Two stabilizing components are located on the back of the two moving plates 407 respectively, and the stabilizing components are... The rear side wall of the inner cavity of hopper 1 is fixed. The stabilizing component consists of two sliders 411 and two slide rails 412. The two sliders 411 are fixed to the back of the two moving plates 407 respectively. The slide rails 412 are slidably connected to the inside of the sliders 411 and are fixed to the rear side wall of the inner cavity of hopper 1. The sliders 411 and slide rails 412 are used to support the moving frame 406 and the two moving plates 407, and make the movement of the moving plates 407 smoother, thereby improving the stability of the moving plates 407 during operation.

[0030] In this embodiment, the filter assembly includes two connecting rods 408, a protective plate 409, and a filter plate 410. The front of the protective chamber 401 is provided with a moving hole for the connecting rods 408 to move. A flexible plate fixed to the outer surface of the connecting rods 408 is fixed inside the moving hole. The flexible plate prevents concrete from flowing into the interior of the protective chamber 401 from the moving hole, thus preventing concrete from accumulating inside the protective chamber 401 and making the operation of the filter mechanism 4 more stable.

[0031] Two connecting rods 408 are fixed to the front of the two moving plates 407 respectively. The protective plate 409 is fixed to the front of the connecting rods 408, and the protective plate 409 is slidably connected to the top of the connecting plate 3. Two positioning blocks are fixed to the bottom of the protective plate 409. The positioning blocks are inverted T-shaped. The top of the connecting plate 3 is provided with a positioning groove that matches the positioning blocks. Through the setting of the positioning blocks and positioning grooves, the filter mechanism 4 can be supported, and the movement of the filter mechanism 4 can be more stable. The filter plate 410 is fixed to the inside of the protective plate 409.

[0032] It should be noted that when the concrete falls into the filter assembly, the operation of the drive assembly enables the filter assembly to move back and forth, thereby enabling the filter plate 410 to filter the concrete.

[0033] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0034] The working principle of the above embodiments is as follows: In use, concrete is poured into the top of the hopper 1, allowing it to fall onto the filter plate 410. The motor 403 is then started, causing the rotating rod 404 to rotate. This rotation drives the eccentric wheel 405 to rotate, which in turn contacts the interior of the moving frame 406, allowing the frame to move left and right. This movement of the frame then drives the two moving plates 407 to move left and right. The movement of the connecting rod 408 will cause the connecting rod 408 to move, which in turn causes the protective plate 409 to move back and forth. This, in turn, causes the protective plate 409 to move the filter plate 410 back and forth. The movement of the filter plate 410 will cause the concrete on the filter plate 410 to be filtered, thereby screening out large aggregate particles in the concrete and preventing the hopper 1 from becoming blocked. The filtered concrete will fall down to the discharge port 5, and then, through the action of the guide plate 6 at the bottom of the discharge port 5, the concrete can stably enter the pouring hole.
