Description

Technical Field

[0001] This application relates to the field of concrete technology, and in particular to a flow control device for a concrete aggregate feed hopper. Background Technology

[0002] A concrete and aggregate feed hopper is a piece of equipment used for transporting and storing building materials. It is typically made of metal and is characterized by its durability, simple structure, and ease of operation. It is mainly used for transporting and storing building materials such as concrete and aggregate, and is commonly found on construction sites.

[0003] The utility model patent with announcement number CN210593457U proposes a sand and gravel feeding hopper, which relates to the field of concrete processing. It includes a support frame, an outer hopper fixedly connected to the support frame, an inner hopper elastically arranged inside the outer hopper, a first output port at the bottom of the outer hopper, a second output port at the bottom of the inner hopper, the second output port facing the first output port, and a vibrating element fixedly connected to the surface of the inner hopper near the inner wall of the outer hopper.

[0004] The aforementioned type of sand and gravel feed hopper cannot adjust the discharge flow rate of the feed hopper according to the required sand and gravel content of the concrete when producing concrete of different specifications, which reduces the applicability of the equipment. Utility Model Content

[0005] The purpose of this invention is to solve or at least alleviate the problem that an existing sand and gravel feed hopper cannot adjust the discharge flow rate of the feed hopper according to the required sand and gravel content of the concrete when producing concrete of different specifications, which reduces the applicability of the equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A flow control device for a concrete aggregate feed hopper includes a feed hopper body. The feed hopper body is provided with a flow control component for controlling the material discharge and a clogging component for preventing blockage. The flow control component includes two fixed blocks fixedly connected to the bottom end of one side wall of the feed hopper body. A rotating rod is fixedly connected between the two fixed blocks. An L-shaped block is sleeved on the rotating rod. A rotating plate for blocking the discharge port of the feed hopper body is provided on the lower surface of the feed hopper body. One end of the rotating plate is fixedly connected to the L-shaped block. Fixed rods are fixedly connected to one side wall of the feed hopper body and one side wall of the rotating plate. An electric push rod is provided between the two fixed rods. The two ends of the electric push rod are respectively sleeved on the fixed rods and form a rotatable connection.

[0008] By adopting the above technical solution, during use, concrete aggregate is first put into the hopper body. Then, according to the required discharge flow rate, the electric push rod is activated to push the rotating plate, causing the L-shaped block to rotate on the rotating rod. This causes the rotating plate to swing and tilt, controlling the opening size of the discharge port of the hopper body, thereby controlling the discharge flow rate of concrete aggregate. This avoids the problem of not being able to adjust the discharge flow rate of the hopper according to the required aggregate content of the concrete, which would reduce the applicability of the equipment.

[0009] Optionally, the unblocking component includes a rotating shaft disposed at the bottom of the inside of the feed hopper body. The two ends of the rotating shaft are respectively rotatably connected to the two side walls inside the feed hopper body. A plurality of unblocking plates in an annular array are fixedly connected to the side wall of the rotating shaft. A drive motor for driving the rotating shaft to rotate is installed on the side wall of the feed hopper body away from the electric push rod.

[0010] By adopting the above technical solution, the drive motor is started to rotate the rotating shaft, which in turn drives the unblocking plate to rotate. This allows the concrete and gravel at the bottom of the feed hopper to be turned over and flow, preventing the concrete and gravel from accumulating inside the feed hopper and causing blockages, which would make it difficult for the concrete and gravel to be discharged.

[0011] Optionally, a rubber pad is fixedly connected to the upper surface of the rotating plate.

[0012] By adopting the above technical solutions, the rubber pad can reduce the force of the collision between the rotating plate and the hopper body when the electric push rod is in contact with the rotating plate, thus preventing damage.

[0013] Optionally, each of the fixed rods is threaded with a limiting plate to prevent the electric push rod from falling off.

[0014] By adopting the above technical solution, the limit plate can be removed by rotating it, making it convenient to disassemble and replace the electric push rod.

[0015] Optionally, the two side walls at both ends of the electric push rod are rotatably connected with multiple ball bearings to prevent the electric push rod from locking.

[0016] By adopting the above technical solutions, the friction between the two side walls at both ends of the electric push rod and the limiting plate, the feed hopper body and the rotating plate can be reduced by the ball bearings, preventing them from sticking together and making it difficult for the electric push rod to rotate on the fixed rod when it is pushed.

[0017] Optionally, each of the fixed rods has a slot at one end, and a locking rod is hinged to the side wall of the limiting plate away from the electric push rod. The locking rod is located in the slot and a magnetic block that is attracted and connected to the limiting plate is fixedly connected to the other side wall.

[0018] By adopting the above technical solution, after the limit plate is installed, the locking rod is inserted into the slot by swinging the locking rod, and then the magnetic block is attracted and connected to the limit plate. This can prevent the friction between the ball and the limit plate when the electric push rod rotates on the fixed rod, which would cause the limit plate to rotate and fall off the fixed rod.

[0019] Optionally, a spiral guard plate is fixedly connected to the top of the feed hopper body.

[0020] By adopting the above technical solutions, the U-shaped protective plate can shield the electric push rod and drive motor, preventing the spilled concrete and gravel from directly impacting the electric push rod and drive motor and causing damage.

[0021] In summary, the beneficial effects of this application are as follows:

[0022] 1. This application utilizes the coordinated arrangement of structures such as L-shaped blocks, rotating plates, and electric push rods. During use, concrete aggregate is first fed into the hopper body. Then, based on the required discharge flow rate, the electric push rod is activated to push the rotating plate, causing the L-shaped blocks to rotate on the rotating rod. This causes the rotating plate to swing and tilt, controlling the opening size of the hopper body's discharge port, thereby controlling the discharge flow rate of concrete aggregate. This minimizes the problem of not being able to adjust the hopper's discharge flow rate according to the required aggregate content of the concrete, which would reduce the equipment's applicability.

[0023] 2. By starting the drive motor, the rotating shaft rotates, which in turn drives the unblocking plate to rotate. This allows the concrete and gravel at the bottom of the feed hopper to turn over and flow, preventing the concrete and gravel from accumulating inside the feed hopper and causing blockages, which would make it difficult for the concrete and gravel to be discharged.

Detailed Implementation

[0029] The following will refer to the appendix in the embodiments of this utility model. Figure 1-4 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] Please see Figure 1-3 A flow control device for a concrete aggregate feed hopper includes a feed hopper body 1. The feed hopper body 1 is provided with a flow control component for controlling the material discharge and a clogging component for preventing blockage. The flow control component includes a fixed block 2, a rotating rod 3, an L-shaped block 4, a rotating plate 5, a fixed rod 6, and an electric push rod 7.

[0031] Two fixed rod blocks are provided and fixedly connected to the bottom sides of one side wall of the feed hopper body 1. A rotating rod 3 is provided between the two fixed blocks 2 and its two ends are fixedly connected to the fixed blocks 2 respectively. An L-shaped block 4 is sleeved on the rotating rod 3. A rotating plate 5 is provided on the lower surface of the feed hopper body 1 to block the discharge port of the feed hopper body 1. One end of the rotating plate 5 is fixedly connected to the L-shaped block 4. Two fixed rods 6 are provided and fixedly connected to one side wall of the feed hopper body 1 and one side wall of the rotating plate 5 respectively. An electric push rod 7 is provided between the two fixed rods 6. The two ends of the electric push rod 7 are sleeved on the fixed rods 6 and form a rotatable connection, used to push the rotating plate 5 to swing. The size of the discharge port of the feed hopper body 1 is adjusted. A flow controller is installed on one side wall of the feed hopper body 1. It has a built-in microprocessor and communication module and is connected to the external main control system via wireless signal. The feed hopper body 1 is equipped with photoelectric sensors and weighing sensors to detect changes in the height and weight of concrete aggregates and transmit the data to the flow controller. The flow controller calculates the required flow rate based on the set parameters and commands the main control system via wireless signal. The main control system then controls the extension and retraction of the electric push rod 7 through a preset program to rotate the rotating plate 5, thereby adjusting the opening and closing degree of the feed port to achieve precise flow control.

[0032] In use, concrete aggregate is first put into the feed hopper body 1. Then, according to the required discharge flow rate, the electric push rod 7 is activated to push the rotating plate 5, so that the L-shaped block 4 rotates on the rotating rod 3, causing the rotating plate 5 to swing and tilt, thereby controlling the opening size of the discharge port of the feed hopper body 1 and thus controlling the discharge flow rate of concrete aggregate. This avoids the problem of not being able to adjust the discharge flow rate of the feed hopper according to the required aggregate content of the concrete, which would reduce the applicability of the equipment.

[0033] Reference Figure 4 The unblocking component includes a rotating shaft 8 located at the bottom of the inside of the hopper body 1. The two ends of the rotating shaft 8 are rotatably connected to the two side walls inside the hopper body 1. Multiple unblocking plates 9 in a ring array are fixedly connected to the side wall of the rotating shaft 8. A drive motor 10 for driving the rotating shaft 8 is installed on the side wall of the hopper body 1 away from the electric push rod 7. By starting the drive motor 10, the rotating shaft 8 is rotated, which drives the unblocking plates 9 to rotate. This can cause the concrete and gravel at the bottom of the inside of the hopper body 1 to turn over and flow, preventing the concrete and gravel from accumulating inside the hopper body 1 and causing blockage, making it difficult for the concrete and gravel to be discharged.

[0034] Reference Figure 2 A rubber pad 11 is fixedly connected to the upper surface of the rotating plate 5. The rubber pad 11 can reduce the force of the collision between the rotating plate 5 and the hopper body 1 when the electric push rod 7 puts the rotating plate 5 into contact with the hopper body 1, thus preventing damage.

[0035] Reference Figure 2 and Figure 3 Each of the fixed rods 6 is threaded with a limiting plate 12 to prevent the electric push rod 7 from falling. By rotating the limiting plate 12, the limiting plate 12 can be removed, making it convenient to disassemble and replace the electric push rod 7.

[0036] Reference Figure 3 Multiple ball bearings 13 are rotatably connected to the two side walls at both ends of the electric push rod 7 to prevent the electric push rod 7 from locking. The ball bearings 13 can reduce the friction between the two side walls at both ends of the electric push rod 7 and the limiting plate 12, the feed hopper body 1 and the rotating plate 5 respectively, and prevent them from sticking together. When the electric push rod 7 is pushed, it is difficult for it to rotate on the fixed rod 6.

[0037] Reference Figure 3Each of the fixed rods 6 has a slot 14 at one end. The side wall of the limiting plate 12 away from the electric push rod 7 is hinged with a locking rod 15. The locking rod 15 is located in the slot 14 and the other side wall is fixedly connected to a magnetic block 16 that is attracted to the limiting plate 12. After the limiting plate 12 is installed, the locking rod 15 is swung to lock it into the slot 14, and then the magnetic block 16 is attracted to the limiting plate 12. This can prevent the friction between the ball 13 and the limiting plate 12 when the electric push rod 7 rotates on the fixed rod 6, which would cause the limiting plate 12 to rotate and fall off the fixed rod 6.

[0038] Reference Figure 1 The top of the feed hopper body 1 is fixedly connected to a spiral protective plate 17. The spiral protective plate 17 can shield the electric push rod 7 and the drive motor 10, preventing the spilled concrete and gravel from directly impacting the electric push rod 7 and the drive motor 10 and causing damage to them.

[0039] The implementation principle of this application is as follows: When in use, the user first puts concrete aggregate into the feed hopper body 1. Then, according to the required discharge flow rate, the user starts the electric push rod 7 to push the rotating plate 5, causing the L-shaped block 4 to rotate on the rotating rod 3. This causes the rotating plate 5 to swing and tilt, controlling the opening size of the discharge port of the feed hopper body 1, thereby controlling the discharge flow rate of the concrete aggregate. At the same time, the user starts the drive motor 10 to rotate the rotating shaft 8, which in turn drives the unblocking plate 9 to rotate. This allows the concrete aggregate at the bottom of the feed hopper body 1 to turn over and flow, preventing the concrete aggregate from accumulating inside the feed hopper body 1 and causing blockages, which would make it difficult to discharge the concrete aggregate. This avoids the problem of not being able to adjust the discharge flow rate of the feed hopper according to the required aggregate content of the concrete, which would reduce the applicability of the equipment.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model.
