Description

Technical Field

[0001] The utility model relates to the technical field of flow scales, in particular to an adjustable feeding device for a flow scale. Background Technique

[0002] Flow scales are mainly used for automatically accumulating weights and statistics during the process of grain in and out of storage and in the technological process. When processing paddy, flow scales are often used.

[0003] A Chinese patent with the publication number CN109489791A discloses an electronic bulk material flow scale, which includes a flow scale body. A limiting rail is fixedly connected to the top of the bottom plate. A limiting shaft is fixedly connected to the inner wall of the limiting rail. A sliding block is sleeved on the surface of the limiting shaft. One side of the sliding block is welded with a fixing plate. A hydraulic cylinder is fixed to the top of the bottom plate. A locking hole is provided in the limiting rail. The present invention solves the problem that the height of the existing electronic bulk material flow scale is mostly fixed. Therefore, when weighing, the height of the particles is relatively high, and it is easy for some particles to pop out of the flow scale during the falling process, resulting in waste of grain.

[0004] However, the above flow scale still has some problems. In practical applications, the feeding speed cannot be adjusted according to specific requirements, which will cause unstable supply of paddy during the production process. Either too much feeding leads to blockage, affecting the normal operation and service life of the equipment; or too little feeding, resulting in reduced production efficiency. Therefore, an adjustable feeding device for a flow scale is proposed for the above problems. Summary of the Utility Model

[0005] In order to make up for the deficiencies of the prior art and solve the problems raised in the background technique, the utility model proposes an adjustable feeding device for a flow scale.

[0006] The technical solution adopted by the utility model to solve its technical problems is: an adjustable feeding device for a flow scale according to the utility model includes a box body. A feeding hopper is connected to the top side of the box body. A chute is provided inside the feeding hopper. A rotating shaft is rotatably installed on the top side of the box body. Four support rods are fixedly connected to the outer wall of the rotating shaft at equal intervals. One end of the support rod is fixedly connected with a disc. The disc is slidably installed inside the chute. Different-sized feeding ports are respectively provided inside the disc. A turntable is installed on the outer wall of the rotating shaft. Four arc-shaped grooves and U-shaped grooves are respectively provided at equal intervals inside the turntable, and the arc-shaped grooves and the U-shaped grooves are arranged alternately. A stepping motor is installed on one side of the box body. The output end of the stepping motor is installed with a sector plate that is matched with the arc-shaped groove. A connecting rod is installed on the bottom side of the sector plate. A convex rod that is matched with the U-shaped groove is fixedly connected to the top side of the connecting rod, realizing the adjustment of the feeding speed and improving the measurement accuracy of the flow scale.

[0007] Preferably, two support plates are symmetrically installed on both inner walls of the box body. Sleeve barrels are fixedly connected to the top sides of the support plates. Springs are fixedly connected inside the sleeve barrels. One ends of the springs are fixedly connected to movable rods. One ends of the movable rods slide through and extend to the top sides of the sleeve barrels and are jointly fixedly connected to a sieve mesh. The length of the sieve mesh is less than or equal to the inner wall width of the box body, and the sieve mesh is arc-shaped, which can effectively separate large particle impurities in the paddy rice and improve the purity of the paddy rice.

[0008] Preferably, a driving motor is installed on one side of the box body. A rotating shaft is installed at the output end of the driving motor. An eccentric wheel is installed on the outer wall of the rotating shaft. When the eccentric wheel operates, it will contact the bottom side of the sieve mesh, promoting the movement of the sieve mesh and improving the effect of the sieve mesh operation.

[0009] Preferably, a mounting plate is installed on the bottom side of the box body. A discharge hopper is connected through the bottom side of the mounting plate. Support legs are fixedly installed at the four corner positions of the mounting plate. Connecting shafts are rotatably installed at the bottom sides of the support legs. A mounting frame is installed at the bottom sides of the connecting shafts. Wheels are installed inside the mounting frame through pin shafts, facilitating the movement of the device and the discharge of paddy rice.

[0010] Preferably, a discharge port is formed on one side of the box body inside the sieve mesh. A plug is movably installed inside the discharge port. A fixed buckle is fixed on one side of the plug. A perspective window is formed on one side of the box body, facilitating the discharge of the screened impurities.

[0011] Preferably, a control panel is installed on the other side of the box body. The control panel is used for the operation control of the electrical components inside the device, realizing the centralized control of the electrical components in the device and improving the convenience of operating the device.

[0012] The beneficial effects of the present utility model are as follows:

[0013] 1. When the stepping motor of the present utility model is started, the sector disk is driven to rotate, and the convex rod will enter the arc-shaped groove, thereby driving the turntable and the rotating shaft to rotate by a certain angle, causing the disk to also rotate accordingly. Different-sized feeding ports are formed on the disk. When a suitable feeding port is aligned with the bottom of the feeding hopper, the paddy rice can enter the box body through the feeding port, thus realizing the adjustment of the feeding amount and improving the measurement accuracy of the flow scale.

[0014] 2. After the driving motor of the present utility model is started, it drives the rotating shaft and the eccentric wheel to rotate. The eccentric wheel will push the sieve mesh upward. The movable rod will stretch the spring and slide upward inside the sleeve barrel, thereby driving the sieve mesh to displace upward. When the eccentric wheel continues to rotate and gradually leaves the sieve mesh, the elastic potential energy of the spring is released, pushing the movable rod downward, and then causing the sieve mesh to fall back to produce a vibration effect, which can effectively separate large particle impurities in the paddy rice and improve the purity of the paddy rice.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0023] Please refer to Figures 1-4As shown in the figure, an adjustable feeding device for a flow scale includes a box body 1. A feeding hopper 2 is connected to the top side of the box body 1. A chute 3 is provided inside the feeding hopper 2. A rotating shaft 4 is rotatably installed on the top side of the box body 1. Four support rods 5 are fixedly connected to the outer wall of the rotating shaft 4 at equal intervals. One end of the support rod 5 is fixedly connected to a disc 6. The disc 6 is slidably installed inside the chute 3. Different-sized feeding ports are respectively provided inside the disc 6. A turntable is installed on the outer wall of the rotating shaft 4. Four arc-shaped grooves 7 and U-shaped grooves 8 are respectively provided at equal intervals inside the turntable, and the arc-shaped grooves 7 and the U-shaped grooves 8 are arranged alternately. A stepping motor 9 is installed on one side of the box body 1. A sector plate 10 that is matched with the arc-shaped groove 7 is installed at the output end of the stepping motor 9. A connecting rod 11 is installed at the bottom side of the sector plate 10. A convex rod 12 that is matched with the U-shaped groove 8 is fixedly connected to the top side of the connecting rod 11. A control panel 30 is installed on the other side of the box body 1. During operation, in actual application, the feeding speed cannot be adjusted according to specific requirements, which will cause unstable supply of rice during the production process. Either too much feeding leads to blockage, affecting the normal operation and service life of the equipment; or too little feeding, resulting in reduced production efficiency. When the feeding needs to be adjusted, the operator starts the stepping motor 9 through the control panel 30. The stepping motor 9 drives the sector plate 10 to rotate. During the rotation of the sector plate 10, the convex rod 12 will enter the arc-shaped groove 7, thereby driving the turntable and the rotating shaft 4 to rotate a certain angle, causing the disc 6 to rotate accordingly. Different-sized feeding ports are provided on the disc 6. When the appropriate feeding port is aligned with the bottom of the feeding hopper 2, the rice can enter the box body 1 through the feeding port, thus realizing the adjustment of the feeding amount and improving the measurement accuracy of the flow scale.

[0024] Please refer to Figure 1 、 2 As shown in FIGS. 4 and 5, two support plates 13 are symmetrically installed on both inner walls of the box body 1. Sleeves 14 are fixedly connected to the top sides of the support plates 13. Springs 15 are fixedly connected inside the sleeves 14. One end of each spring 15 is fixedly connected to a movable rod 16. One end of each movable rod 16 slidably penetrates and extends to the top side of the sleeve 14 and are jointly fixedly connected to a sieve 17. The length of the sieve 17 is less than or equal to the inner wall width of the box body 1, and the sieve 17 is arc-shaped.

[0025] One side of the box body 1 is equipped with a driving motor 18, the output end of the driving motor 18 is equipped with a rotating shaft 19, and an eccentric wheel 20 is installed on the outer wall of the rotating shaft 19. The eccentric wheel 20 will contact the bottom side of the screen 17 during operation; during work, the flow scale is used to automatically accumulate the weight and statistics during the process of grain entering and leaving the warehouse. When processing paddy rice, the flow scale is often used, and the impurities in the paddy rice are usually screened to improve the yield rate of the paddy rice. After the driving motor 18 is started, it drives the rotating shaft 19 and the eccentric wheel 20 to rotate. The eccentric wheel 20 will push the screen 17 upward, and the movable rod 16 will stretch the spring 15 and slide upward in the sleeve 14, thereby driving the screen 17 to move upward. When the eccentric wheel 20 continues to rotate and gradually leaves the screen 17, the elastic potential energy of the spring 15 is released, pushing the movable rod 16 to move downward, and then causing the screen 17 to fall back to produce a vibration effect. During the vibration process, the paddy rice entering the box body 1 can be screened and filtered, and the large-particle impurities in the paddy rice can be effectively separated, improving the purity of the paddy rice.

[0026] Please refer to Figure 1 、 2 As shown in FIGS. 4 and 5, a mounting plate 21 is installed on the bottom side of the box body 1. A discharge hopper 22 is connected through the bottom side of the mounting plate 21. Support legs 23 are fixedly installed at the four corner positions of the mounting plate 21. Connecting shafts 24 are rotatably installed at the bottom sides of the support legs 23. An installation frame 25 is installed at the bottom side of the connecting shaft 24. Wheels 26 are installed inside the installation frame 25 through pin shafts.

[0027] A discharge port is provided inside the box body 1 on one side of the screen 17. A plug 27 is movably installed inside the discharge port. A fixing buckle 28 is fixed on one side of the plug 27. A viewing window 29 is provided on one side of the box body 1; during work, since the storage positions of the paddy rice are different, the device is moved to a suitable position through the cooperation of the wheels 26. After the paddy rice is screened and processed, it is discharged from the box body 1 through the discharge hopper 22. When it is necessary to discharge the large-particle impurities, the plug 27 is pulled out through the fixing buckle 28, and these paddy rice are discharged from the discharge port. The viewing window 29 allows the operator to observe the internal situation of the box body 1 from the outside.

[0028] Working principle: The device is moved to a suitable position through the cooperation of the wheels 26. When it is necessary to adjust the feeding, the operator starts the stepping motor 9 through the control panel 30. The stepping motor 9 drives the sector plate 10 to rotate. During the rotation of the sector plate 10, the convex rod 12 will enter the arc groove 7, thereby driving the turntable and the rotating shaft 4 to rotate a certain angle, so that the disc 6 will also rotate accordingly. Different-sized feeding ports are provided on the disc 6. When the appropriate feeding port is aligned with the bottom of the feeding hopper 2, the paddy rice can enter the box body 1 through the feeding port, thereby realizing the adjustment of the feeding amount and improving the measurement accuracy of the flow scale;

[0029] After the drive motor 18 starts, it drives the rotating shaft 19 and the eccentric wheel 20 to rotate. The eccentric wheel 20 will push the screen 17 upward. The movable rod 16 will stretch the spring 15 and slide upward in the sleeve 14, thereby driving the screen 17 to move upward. When the eccentric wheel 20 continues to rotate and gradually moves away from the screen 17, the elastic potential energy of the spring 15 is released, pushing the movable rod 16 to move downward, and then causing the screen 17 to fall back to produce a vibration effect. During the vibration process, the paddy entering the box 1 can be screened and filtered, and the large particle impurities in the paddy can be effectively separated, improving the purity of the paddy;

[0030] After the paddy is screened and processed, it is discharged from the box 1 through the discharge hopper 22. When it is necessary to discharge the large particle impurities, the plug 27 is pulled out through the fixed buckle 28, and these paddy are discharged from the discharge port. The perspective window 29 allows the operator to observe the internal situation of the box 1 from the outside.
