Technical Field
[0001] This invention relates to the field of rice processing, specifically to a rice processing device capable of precisely controlling the amount of rice processed and its method of use. Background Technology
[0002] Rice screening is an important step in rice processing. Its purpose is to remove impurities, foreign objects, and substandard products to ensure the quality and purity of the final product. In the rice screening process, a series of equipment and methods are usually used to achieve effective screening and separation.
[0003] Before screening, rice typically undergoes a preliminary cleaning process to remove surface impurities, dust, and husk fragments. This is done through air purging, vibration screening, or the use of cleaning devices; vibration screening is one of the most common rice screening methods. By placing the rice on a sieve and applying vibration, the rice is separated into layers according to size and weight, thus separating out larger impurities and substandard products.
[0004] Currently, existing rice processing screening equipment cannot accurately quantify the rice during processing. Furthermore, after each screening, the impurities remaining on the screen plate need to be manually removed. This usually requires removing the screen plate from the screening box, then cleaning it using a cleaning device or manually, and finally reinstalling the cleaned screen plate. This affects processing efficiency during batch processing. Summary of the Invention
[0005] The purpose of this invention is to provide a rice processing device and its method of use that can precisely control the amount of rice processed, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: A rice processing device capable of precisely controlling the amount of rice processed, including A screening box, wherein a frame is movably installed at the upper part of the screening box, and an opening and closing mechanism is provided below the frame; The outer casing is located on the outside of the top right side of the screening box, and a vibration mechanism is installed inside the outer casing; The feeding box is located on the outside of the bottom right side of the screening box, and a quantitative mechanism is provided inside the feeding box; The guide hoppers are symmetrically arranged on both sides of the lower part of the screening box. The screening box is equipped with a steering mechanism located directly above the top of the two guide hoppers.
[0007] Furthermore, the opening and closing mechanism includes a sieve plate, a fixing block, and a first electric push rod. The first electric push rod is movably mounted on both ends of the side of the frame away from the outer shell via a rotating shaft. The side of the sieve plate close to the outer shell is movably connected to the bottom of the frame via a rotating shaft. Fixing blocks are symmetrically arranged on both ends of the other side of the sieve plate. The output shaft of the first electric push rod is movably connected to the fixing block via a rotating shaft.
[0008] Furthermore, the vibration mechanism includes a first motor, a transmission shaft, a first cam, and a vibration block. The first motor is located below the bottom of the housing, and the output shaft of the first motor is fixedly connected to the transmission shaft. The first cam is located below the middle of the transmission shaft, and the vibration block is located on the outer side of the frame near the housing. The first cam is movably connected to the vibration block.
[0009] Furthermore, the vibration mechanism also includes guide rods, a first spring, and movable blocks. A pair of guide rods are provided on both the top and bottom sides of the screening box near the frame. Movable blocks are fixedly installed on both the top and bottom sides of the frame. The movable blocks are movably connected to the guide rods. The movable blocks and the screening box located outside the guide rods are movably connected by the first spring.
[0010] Furthermore, a second cam is provided at the top of the drive shaft, a hanger is provided on the right side of the top of the screening box, a strike rod is movably sleeved inside the hanger, the middle part of the strike rod is movably connected to the right side of the hanger through a second spring, the right end of the strike rod is movably connected to the second cam, a feeding hopper is connected to the middle of the top of the screening box, and the other end of the strike rod is movably connected to the outer side of the bottom end of the feeding hopper.
[0011] Furthermore, the quantitative mechanism includes a receiving box, a through groove, a second electric push rod, and a baffle. The receiving box is movably installed inside the feeding box. The second electric push rod is fixedly installed inside the screening box on the lower right side near the feeding box. A through groove is opened between the guide hopper on the right side and the feeding box. A baffle is vertically set on the left side of the output shaft of the second electric push rod. A weighing device is set inside the lower part of the feeding box.
[0012] Furthermore, the steering mechanism includes a second motor and a tilting plate. The second motor is located on the outer side of the middle of the screening box, and the output shaft of the second motor is fixedly connected to the tilting plate.
[0013] A method for using rice processing equipment capable of precisely controlling the amount of rice processed includes the following steps: Step 1: Put the rice to be screened into the frame from the hopper, then start the first motor. After the first motor starts, it controls the drive shaft to rotate. When the drive shaft rotates, it drives the first cam to hit the vibrating block. The vibrating block controls the screen plate at the bottom of the frame to separate the rice from the impurities. The impurities remain on the screen plate, and the rice falls into the flipping plate below. Step two: At the same time as the first motor starts, the transmission shaft will also drive the second cam to rotate. After the second cam rotates, it will strike the impact rod, and the other end of the impact rod will strike the feeding hopper. The rice in the feeding hopper will be quickly shaken down into the frame. Step 3: After screening, the rice falls into the trough along the flip plate and enters the receiving box inside the feeding box. When the weight of the rice in the receiving box reaches the set value of the weighing device, the second electric push rod is activated. After the second electric push rod is activated, the baffle is lowered to block the trough, and then the receiving box is taken out. Step 4: After screening is completed, control the second motor to start. After the second motor starts, it drives the flipping plate to rotate counterclockwise by 45°. At this time, the end of the flipping plate near the feeding box is raised, and the other end is lowered and abuts against the top of the guide hopper on the left. Step 5: Then, start the first electric actuator. After the first electric actuator starts, it pushes the fixed block and pushes the screen plate away from the outer shell downward. At this time, the debris on the screen plate will slide down to the bottom flip plate and then fall into the guide hopper on the left.
[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the rice after screening falls into the trough along the flipping plate and enters the receiving box inside the feeding box. When the weight of the rice in the receiving box reaches the set value of the weighing device, the second electric push rod is activated. After the second electric push rod is activated, the baffle is controlled to fall and block the trough. Then the receiving box is taken out, thereby achieving the purpose of convenient quantitative screening. 2. After the screening is completed, the second motor is started. After the second motor starts, it drives the flipping plate to rotate counterclockwise by 45°. At this time, the end of the flipping plate near the feeding box is raised, and the other end is lowered and abuts against the top of the guide hopper on the left. Then, the first electric push rod is started. After the first electric push rod is started, it pushes the fixing block and pushes the end of the screen plate away from the outer shell downward. At this time, the debris on the screen plate will slide to the flipping plate at the bottom and then fall into the guide hopper on the left. This makes it more convenient to remove the screened waste material without having to remove the screening device. Moreover, after the waste material is removed, the feeding mode can be switched. 3. In this invention, when the first motor starts, the transmission shaft will also drive the second cam to rotate. After the second cam rotates, it will strike the impact rod, and the other end of the impact rod will strike the feeding hopper. The rice in the feeding hopper will be quickly shaken down into the frame. This will prevent the rice from getting stuck in the feeding hopper during feeding. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] like Figure 1-6 As shown, the present invention provides a technical solution: A rice processing device capable of precisely controlling the amount of rice processed includes a screening box 1. A frame 2 is movably installed at the upper part of the screening box 1. An opening and closing mechanism is provided below the frame 2. The opening and closing mechanism includes a screen plate 6, a fixing block 7, and a first electric push rod 8. The first electric push rod 8 is movably installed at both ends of the side of the frame 2 away from the outer shell 3 via a rotating shaft. The side of the screen plate 6 close to the outer shell 3 is movably connected to the lower part of the frame 2 via a rotating shaft. Fixing blocks 7 are symmetrically arranged at both ends of the other side of the screen plate 6. The output shaft of the first electric push rod 8 is movably connected to the fixing block 7 via a rotating shaft. Guide hoppers 5 are symmetrically arranged on both sides of the lower part of the screening box 1. A directional mechanism is provided directly above the top of the two guide hoppers 5 in the screening box 1. The directional mechanism includes a second motor 25 and a flipping plate 26. The second motor 25 is located on the outer side of the middle part of the screening box 1. The output shaft of the second motor 25 is fixedly connected to the flipping plate 26. Specifically, after screening is completed, the second motor 25 is started. After the second motor 25 starts, it drives the flipping plate 26 to rotate counterclockwise by 45°. At this time, the end of the flipping plate 26 near the feeding box 4 is raised, and the other end is lowered and abuts against the top of the guide hopper 5 on the left. Then, the first electric push rod 8 is started. After the first electric push rod 8 starts, it pushes the fixing block 7 and pushes the end of the screen plate 6 away from the outer shell 3 downward. At this time, the debris on the screen plate 6 will slide onto the flipping plate 26 at the bottom and then fall into the guide hopper 5 on the left. This makes it more convenient to remove the screened waste material without having to remove the screening device. Moreover, after the waste material is removed, it can be switched to feeding.
[0019] like Figure 3 and Figure 5 As shown, the outer shell 3 is located outside the top right side of the screening box 1. The inner part of the outer shell 3 is equipped with a vibration mechanism, which includes a first motor 9, a transmission shaft 10, a first cam 11, and a vibration block 12. The first motor 9 is located below the bottom of the outer shell 3. The output shaft of the first motor 9 is fixedly connected to the transmission shaft 10. The first cam 11 is located below the middle part of the transmission shaft 10. The vibration block 12 is located on the outer side of the frame 2 near the outer shell 3. The first cam 11 is movably connected to the vibration block 12. The vibration mechanism also includes a guide rod 13, a first spring 14, and a movable block 15. A pair of guide rods 13 are provided on both the top and bottom sides of the screening box 1 near the frame 2. Movable blocks 15 are fixedly installed on both the top and bottom sides of the frame 2. The movable blocks 15 are movably sleeved with the guide rods 13. The movable blocks 15 and the screening box 1 located outside the guide rods 13 are movably connected by the first spring 14. In this embodiment, the rice to be screened is placed into the frame 2 at the feeding hopper 24, and then the first motor 9 is started. After the first motor 9 starts, it controls the transmission shaft 10 to rotate. When the transmission shaft 10 rotates, it drives the first cam 11 to strike the vibrating block 12. The vibrating block 12 controls the sieve plate 6 at the bottom of the frame 2 to separate the rice from the impurities. The impurities remain on the sieve plate 6, and the rice falls onto the flipping plate 26 below, thereby achieving the purpose of facilitating vibration screening.
[0020] like Figure 3 and Figure 6 As shown, the feeding box 4 is located outside the bottom right side of the screening box 1. The feeding box 4 is equipped with a quantitative mechanism, which includes a receiving box 20, a through groove 21, a second electric push rod 22, and a baffle 23. The receiving box 20 is movably installed inside the feeding box 4. The second electric push rod 22 is fixedly installed inside the lower right side of the screening box 1 near the feeding box 4. A through groove 21 is opened between the right guide hopper 5 and the feeding box 4. The output shaft of the second electric push rod 22 is located on the left side of the through groove 21 and the baffle 23 is vertically installed. A weighing device 27 is installed inside the lower part of the feeding box 4. In this embodiment, the sieved rice falls into the trough 21 along the flip plate 26 and enters the receiving box 20 inside the feeding box 4. When the weight of the rice in the receiving box 20 reaches the set value of the weighing device 27, the second electric push rod 22 is activated. After the second electric push rod 22 is activated, the control baffle 23 falls to block the trough 21, and then the receiving box 20 is taken out, thereby achieving the purpose of convenient quantitative sieving.
[0021] like Figure 2 and Figure 5 As shown, a second cam 16 is provided at the top of the drive shaft 10, a hanger 17 is provided on the right side of the top of the internal screening box 1, a strike rod 18 is movably sleeved inside the hanger 17, the middle part of the strike rod 18 is movably connected to the right side of the hanger 17 through a second spring 19, the right end of the strike rod 18 is movably connected to the second cam 16, the top middle of the screening box 1 is connected to the feeding hopper 24, and the other end of the strike rod 18 is movably connected to the outer side of the bottom end of the feeding hopper 24. In this embodiment, when the first motor 9 starts, the transmission shaft 10 will also drive the second cam 16 to rotate. After the second cam 16 rotates, it will strike the impact rod 18. The other end of the impact rod 18 will strike the feeding hopper 24. The rice in the feeding hopper 24 will be quickly shaken down into the frame 2. This will prevent the rice from getting stuck in the feeding hopper 24 when feeding.
[0022] A method for using rice processing equipment capable of precisely controlling the amount of rice processed includes the following steps: Step 1: Put the rice to be screened into the frame 2 from the hopper 24, and then start the first motor 9. After the first motor 9 starts, it controls the transmission shaft 10 to rotate. When the transmission shaft 10 rotates, it drives the first cam 11 to strike the vibrating block 12. The vibrating block 12 controls the sieve plate 6 at the bottom of the frame 2 to separate the rice from the impurities. The impurities remain on the sieve plate 6, and the rice falls onto the flipping plate 26 below. Step 2: At the same time as the first motor 9 starts, the transmission shaft 10 will also drive the second cam 16 to rotate. After the second cam 16 rotates, it hits the impact rod 18. The other end of the impact rod 18 hits the feeding hopper 24, and the rice in the feeding hopper 24 is quickly shaken down into the frame 2. Step 3: After screening, the rice falls into the trough 21 along the flip plate 26 and enters the receiving box 20 inside the feeding box 4. When the weight of the rice in the receiving box 20 reaches the set value of the weighing device 27, the second electric push rod 22 is activated. After the second electric push rod 22 is activated, the control baffle 23 falls down to block the trough 21, and then the receiving box 20 is taken out. Step 4: After the screening is completed, control the second motor 25 to start. After the second motor 25 starts, it drives the flipping plate 26 to rotate counterclockwise by 45°. At this time, the end of the flipping plate 26 near the feeding box 4 is raised, and the other end is lowered and abuts against the top of the guide hopper 5 on the left. Step 5: Then, start the first electric push rod 8. After the first electric push rod 8 is started, it pushes the fixed block 7 and pushes the screen plate 6 away from the outer shell 3 downward. At this time, the debris on the screen plate 6 will slide onto the bottom flip plate 26 and then fall into the guide hopper 5 on the left.
