Description

Technical Field

[0001] This utility model belongs to the field of refractory brick mortar technology, and in particular, it is a refractory brick mortar weighing and feeding device. Background Technology

[0002] In the refractory brick processing process, a weighing and feeding device is required to weigh and feed the refractory brick mortar. However, the existing weighing and feeding device has a fixed feeding port height, which makes it inconvenient to adjust the vertical height of the feeding port. This reduces the free fall length of the refractory brick mortar after flowing out of the feeding port and reduces the weighing and feeding accuracy of the refractory brick mortar.

[0003] In related technologies, a search revealed a Chinese patent document (authorization announcement number CN212023134U) entitled "A Weighing and Feeding Device for Refractory Brick Production." The device includes an extension plate on one side of a support plate, a driver at the upper end of the extension plate, a conveyor roller on the other side of the extension plate, a conveyor belt at the upper end of the conveyor roller, a loading trough at the upper end of the conveyor belt, a rubber tube at the upper end of the loading trough, a feeding hopper at the upper end of the rubber tube, a support frame on one side of the feeding hopper, a support rod on one side of the conveyor belt, and a... The device features a DATA-7302 control processor with a button on one side and a rotating block inside the hopper. This addresses the issues of inaccurate weight distribution in existing weighing and feeding devices, and the problem that powdered raw materials can fly out during descent, leading to unnecessary waste. However, this device does not consider adjusting the vertical height of the discharge port to reduce the free fall length of the refractory brick mortar after it flows out of the port, thus lowering the weighing and feeding accuracy of the refractory brick mortar. Utility Model Content

[0004] The purpose of this invention is to provide a weighing and feeding device for refractory brick mortar to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a refractory brick mortar weighing and feeding device, comprising:

[0006] The main body of the scale for weighing refractory brick mortar has a weighing box for storing refractory brick mortar on the top surface of the scale body and a support plate welded to the bottom surface of the scale body.

[0007] A feeding pipe for refractory brick mortar is provided. A connecting plate is welded to the outer surface of the feeding pipe. Movable plates are welded to both ends of the connecting plate. C-shaped movable frames are welded to both ends of the movable plates. Limiting plates are slidably connected to the inner side wall of the movable frames. An inverted U-shaped support frame is welded to the centrifugal side of the two limiting plates. The two inner side walls of the support frame are slidably connected to the two movable frames. An electric push rod is embedded in the top surface of the support frame. The moving end of the electric push rod is fixedly connected to the movable plate.

[0008] Preferably, the bottom surfaces of the two support frames are fixedly connected to the support plate, and the top surface of the feed pipe is connected to a soft guide pipe.

[0009] Preferably, the outer periphery of the feed pipe is connected to a material tank for storing refractory brick mortar, and a storage plate is welded to the bottom of the material tank.

[0010] Preferably, two pairs of fixing plates are welded symmetrically on the side of the shelf, and the centrifugal side of the two pairs of fixing plates is fixedly connected to the support frame.

[0011] Preferably, the bottom surface of the feed pipe abuts against a baffle plate, and a connecting block is welded to the side of the baffle plate.

[0012] Preferably, a rotating rod is welded to the top surface of the connecting block, and a fixed bearing is interference-fitted to the side of the rotating rod.

[0013] Preferably, a fixing block is embedded in the outer ring of the fixed bearing, and the side of the fixing block is welded to the feed pipe.

[0014] Preferably, the end face of the rotating rod is connected to the output shaft of the rotary motor via a coupling, and the fixed end of the rotary motor is detachably connected to a mounting plate via bolts. The side of the mounting plate is welded to the connecting plate.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0016] This refractory brick mortar weighing and discharging device introduces refractory brick mortar into the weighing box via a feed pipe from a material tank. Under the weighing action of the main scale body, the device weighs and discharges the refractory brick mortar. However, due to the gap between the feed pipe and the weighing box, the suspended portion of the refractory brick mortar exiting the feed pipe and not entering the weighing box is difficult to weigh, reducing the device's weighing and discharging accuracy. Two electric push rods provide power, causing the moving end of the electric push rods to drive the moving plate vertically. With the connection of the connecting plate, the gap between the feed pipe and the weighing box is adjusted, improving the device's weighing and discharging accuracy. The moving frame moves along the path of the support frame and the limiting plate, enhancing the vertical stability of the feed pipe during transmission.

[0017] This refractory brick mortar weighing and feeding device uses a rotary motor to provide power. The output shaft of the motor rotates, driving a rotating rod. During transmission, the rotating rod drives a connecting block to rotate around its axis. The connecting block, in turn, causes a baffle plate to rotate to a designated position, blocking the feeding pipe and controlling the material flow. This also facilitates control over the size of the feeding opening, enhancing the device's precision in weighing and feeding refractory brick mortar. A fixed block and bearing provide support and fixation for the rotating rod, improving its rotational stability and preventing swaying or deviation. The enhanced baffle plate's blocking effect on the feeding pipe during transmission further improves the structural stability of the device's components. Attached Figure Description

[0026] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0027] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0028] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0029] To address the issue of inconvenient adjustment of the vertical height of the discharge port in the refractory brick mortar weighing and discharging device, which reduces the accuracy of weighing and discharging the refractory brick mortar, please refer to [the relevant documentation / reference]. Figures 1 to 5 The structure of the device body includes:

[0030] The main body 2 of the scale for weighing refractory brick mortar has a weighing box 3 for storing refractory brick mortar on its top surface. The refractory brick mortar is introduced into the weighing box 3, so that the scale body 2 can weigh the refractory brick mortar inside the weighing box 3. A support plate 1 is welded to the bottom surface of the scale body 2, and the support plate 1 provides support and fixation for the scale body 2.

[0031] A feeding pipe 9 for refractory brick mortar is set at the top of the weighing box 3, so that the feeding pipe 9 can guide the refractory brick mortar into the weighing box 3, thereby realizing the feeding of the refractory brick mortar of the device. A connecting plate 8 is welded to the outer surface of the feeding pipe 9. The bottom surface of the connecting plate 8 is embedded and fixedly connected to the feeding pipe 9, so that the feeding pipe 9 passes through the top and bottom surfaces of the connecting plate 8. Moving plates 7 are welded to both ends of the connecting plate 8. The two moving plates 7 are welded to the connecting plate 8 on adjacent sides, so that the two moving plates 7 and one connecting plate 8 are combined to form an I-shape. C-shaped moving frames 5 are welded to both ends of the moving plates 7. The inner sidewalls of the two moving frames 5 welded to the same moving plate 7 are centrifugally arranged.

[0032] The inner wall of the movable frame 5 is embedded with a sliding connection of a limiting plate 6. An inverted U-shaped support frame 4 is welded to one side of the centrifugal side of the two limiting plates 6. The two limiting plates 6 are welded to the two inner walls of the support frame 4. The two inner walls of the support frame 4 are slidably connected to the two movable frames 5, so that the movable frame 5 moves along the path of the limiting plate 6 and the support frame 4. During the transmission process, the vertical movement stability of the feed pipe 9 is enhanced, and the structural stability of the device components is improved. An electric push rod 21 is embedded in the top surface of the support frame 4. A through groove is opened on the top surface of the support frame 4. The inner wall of the through groove of the support frame 4 is detachably connected to the fixed end of the electric push rod 21.

[0033] The moving end of the electric push rod 21 is fixedly connected to the moving plate 7. The two electric push rods 21 provide power so that the moving ends of the two electric push rods 21 drive the moving plate 7 to move vertically during the movement. During the transmission process, it is convenient to realize the downward movement of the feeding pipe 9, reduce the distance between the feeding pipe 9 and the weighing box 3, and prevent the part of the refractory brick mortar that has fallen out of the feeding pipe 9 and has not fallen into the weighing box 3 from being difficult to weigh. By reducing the distance between the feeding pipe 9 and the weighing box 3, the amount of refractory brick mortar that has fallen out of the feeding pipe 9 and has not fallen into the weighing box 3 is reduced, thereby improving the weighing and feeding accuracy of the refractory brick mortar of the device.

[0034] The bottom surfaces of the two support frames 4 are fixedly connected to the support plate 1. The support plate 1 provides support and fixation for the two support frames 4. The top surface of the feeding pipe 9 is connected to a soft guide pipe 10. The outer periphery of the guide pipe 10 is connected to a material tank 11 for storing refractory brick mortar. The guide pipe 10 provides a connection to facilitate the introduction of refractory brick mortar from the material tank 11 into the feeding pipe 9. At the same time, the guide pipe 10 has sufficient length to provide conditions for the vertical movement of the feeding pipe 9. The bottom surface of the material tank 11 is welded with a shelf 12. The shelf 12 provides support and fixation for the material tank 11. Two pairs of symmetrically arranged fixing plates 13 are welded to the sides of the shelf 12, so that the four fixing plates 13 are welded to the two sides of the shelf 12. The centrifugal side of the two pairs of fixing plates 13 is fixedly connected to the support frame 4, so that the two support frames 4 and the four fixing plates 13 provide support and fixation for the shelf 12, thereby fixing the position of the material tank 11 and improving the structural stability of the device components.

[0035] A baffle plate 20 is abutted against the bottom surface of the feeding pipe 9. The baffle plate 20 provides a shielding function to prevent the refractory brick mortar from overflowing after weighing and feeding, thus reducing the weighing and feeding accuracy of the refractory brick mortar. A connecting block 19 is welded to the side of the baffle plate 20, and a rotating rod 16 is welded to the top surface of the connecting block 19. The connecting block 19 provides a connection function to facilitate the rotation of the baffle plate 20 around the rotating rod 16. A fixed bearing 17 is interference-fitted to the side of the rotating rod 16. A fixed block 18 is embedded and fixedly connected to the outer ring of the fixed bearing 17. The side of the fixed block 18 is welded to the feeding pipe 9. The fixed bearing 17 and the fixed block 18 fix the rotation position of the rotating rod 16, enhance the rotational stability of the rotating rod 16, prevent the rotating rod 16 from shaking or deviating, and improve the shielding effect of the baffle plate 20 on the feeding pipe 9 during transmission.

[0036] The end face of the rotating rod 16 is connected to the output shaft of the rotary motor 15 via a coupling. The fixed end of the rotary motor 15 is detachably connected to the mounting plate 14 via bolts. The side of the mounting plate 14 is welded to the connecting plate 8. The rotary motor 15 provides power, causing the output shaft of the rotary motor 15 to rotate and drive the rotating rod 16 to rotate. During the transmission process, the baffle plate 20 rotates to a designated position to block the feed pipe 9. At the same time, it is convenient to adjust the blocking range of the baffle plate 20 on the feed pipe 9 and control the rate at which the feed pipe 9 discharges refractory brick mortar.

[0037] The rotary motor 15 and the electric push rod 21 are both existing technologies. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. 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.

[0038] Working principle

[0039] In this refractory brick mortar weighing and feeding device, the user guides the refractory brick mortar in the material tank 11 into the weighing box 3 through the guide pipe 10 and the feeding pipe 9. The scale body 2 weighs the refractory brick mortar inside the weighing box 3, realizing the weighing and feeding of the refractory brick mortar. The electric push rod 21 provides power, and the moving end of the electric push rod 21 moves the moving plate 7, so that the moving frame 5 moves down the path of the limiting plate 6 and the support frame 4. Under the connection of the connecting plate 8, the distance between the feeding pipe 9 and the weighing box 3 is adjusted.

[0040] When the rotary motor 15 is started, the output shaft of the rotary motor 15 rotates, driving the rotating rod 16 to rotate. Under the connection provided by the connecting block 19, the baffle plate 20 rotates around the rotating rod 16 as the axis. After the baffle plate 20 rotates to the designated position, it blocks the feed pipe 9. The fixed block 18 and the fixed bearing 17 make the baffle plate 20 move in a stable circumferential direction.
