Description

Technical Field

[0001] This utility model relates to the field of rice processing technology, and in particular to a vibrating screen for rice processing. Background Technology

[0002] Rice, as one of the most common crops, has seen a corresponding increase in production. During the processing of paddy rice into polished rice, the outer husk and approximately 10% of the total weight of the pericarp, seed coat, outer endosperm, aleurone layer, and embryo are removed. Traditional rice bran, which is the rice bran currently regulated by national standards, is mainly made from the pericarp, seed coat, outer endosperm, aleurone layer, and embryo. Therefore, a small amount of rice husk, dust, and microorganisms are mixed in during processing. Thus, rice bran can only be used as animal feed and is a major byproduct of paddy rice processing. If it is not sieved, it will greatly affect its edibility. Therefore, sieving devices are needed to remove the rice bran from the rice to meet consumer requirements.

[0003] After the rice is sieved, it needs to be stored. Traditionally, a separate conveying device is used to transport the sieved rice to the granary. However, traditional vibrating screens have the disadvantage of being inconvenient for conveying the sieved rice, and this needs to be improved.

[0004] Therefore, this application proposes a vibrating screen for rice processing to solve the problems in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a vibrating screen for rice processing, which can not only achieve the effect of vibrating and screening rice, but also achieve the effect of conveying rice, and can also facilitate the collection of screened impurities and avoid dust affecting the surrounding environment.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a vibrating screen for rice processing, comprising a rice sieve cylinder for screening rice, a conveying pipe, and a control panel;

[0007] A rice sieve cylinder is fixedly installed inside the conveying pipe. A spiral rod is rotatably connected inside the rice sieve cylinder, with both ends of the spiral rod rotatably connected to the conveying pipe. Centrifugal blocks are installed at both ends of the spiral rod. A feed pipe is sealed to one end of the rice sieve cylinder, and one end of the feed pipe passes through the conveying pipe and is equipped with a solenoid valve. A rice discharge pipe is sealed to the other end of the rice sieve cylinder. A waste discharge pipe is sealed to the bottom of the conveying pipe. Three support plates are provided on the conveying pipe. A fixing plate is fixedly connected to one side of one of the three support plates. A control panel and a drive mechanism are fixedly installed on the fixing plate. The drive mechanism is connected to the control panel and the control plate. The control panel, screw rod, and discharge pipe are connected. Under the drive control of the motor via a preset program in the control panel, the screw rod rotates, causing the two centrifugal blocks to rotate and interact with the rice sieve cylinder. This achieves the effect of conveying and vibrating the rice while screening it, improving convenience and efficiency. At the same time, the industrial vacuum cleaner is driven and controlled by the preset program in the control panel. The design of the conveying pipe, discharge pipe, corresponding hoses, and air inlet allows for the collection of impurities and dust generated during rice screening, improving product quality and convenience.

[0008] A further feature of this invention is that each of the three support plates has a sliding groove, and each of the three sliding grooves has a transmission plate slidably connected to it. Each of the three transmission plates is fixedly sleeved on the conveying pipe. The solenoid valve is connected to the control panel. Through the cooperation between the three support plates and the three transmission plates, the conveying pipe can vibrate up and down.

[0009] A further feature of this invention is that springs are fixedly installed at the bottom of each of the three transmission plates, and one end of each of the three springs is fixedly connected to the three support plates respectively. The vibration energy is dissipated by the elastic potential energy generated when the three springs are stretched or compressed, thus preventing the equipment from shaking violently.

[0010] A further feature of this invention is that the driving mechanism includes a motor, a transmission rod, a sleeve, and an industrial vacuum cleaner. The motor is fixedly mounted on the fixing plate and connected to the control panel. The speed of the motor can be adjusted through a preset program in the control panel.

[0011] A further feature of this invention is that: a transmission rod is fixedly connected to the output end of the motor, a sleeve is slidably sleeved on the transmission rod for transmission, a reinforcing plate is movably sleeved on the sleeve, and the reinforcing plate is fixedly connected to the corresponding support plate to improve stability.

[0012] A further feature of this invention is that a first bevel gear is fixedly connected to one end of the sleeve, a second bevel gear is meshed with the first bevel gear, and one side of the second bevel gear is fixedly connected to one end of the spiral rod for transmission and is a detachable connection.

[0013] A further feature of this invention is that an L-shaped plate is rotatably fitted onto the sleeve, and one end of the L-shaped plate is rotatably connected to the spiral rod, which is a detachable connection. The L-shaped plate helps to prevent slippage between bevel gear one and bevel gear two.

[0014] A further feature of this invention is that an industrial vacuum cleaner is fixedly mounted on the fixed plate, one end of the industrial vacuum cleaner is sealed with a flexible hose, one end of the flexible hose is sealed with the waste discharge pipe, the industrial vacuum cleaner is connected to the control panel, and the industrial vacuum cleaner is driven and controlled by a preset program in the control panel. The design of the cooperation between the conveying pipe, the waste discharge pipe, the corresponding flexible hose and the air inlet enables the collection of impurities and dust generated by rice sieving, thereby improving product quality and convenience.

[0015] A further feature of this invention is that both ends of the spiral rod are threaded with fastening bolts, which are detachable connections. One side of each of the two fastening bolts abuts against the two centrifugal blocks, thereby limiting and fixing the two centrifugal blocks.

[0016] A further feature of this invention is that an air inlet is provided at one end of the conveying pipe. The air inlet allows the cavity outside the conveying pipe to enter the conveying pipe, and the resulting airflow pushes the debris and dust accumulated on the bottom plate of the conveying pipe toward the discharge pipe, thereby facilitating the industrial vacuum cleaner to pick up the debris and dust.

[0017] The beneficial effects of this utility model are as follows: Under the drive control of the motor through the preset program in the control panel, the screw rod can rotate and drive the two centrifugal blocks to rotate and act on the rice sieve cylinder, thereby achieving the effect of conveying and vibrating the rice at the same time, improving convenience and efficiency. At the same time, the industrial vacuum cleaner is driven and controlled through the preset program in the control panel, and the design of the cooperation between the conveying pipe, the waste discharge pipe, the corresponding hose and the air inlet can achieve the effect of sucking up and collecting the impurities and dust generated by the rice sieve, improving product quality and convenience, and making it more practical.

[0028] Reference Figures 1-6 A vibrating screen for rice processing includes a rice screen cylinder 2 for screening rice, a conveying pipe 1, and a control panel 11.

[0029] A rice sieve cylinder 2 is fixedly installed inside the conveying pipe 1. A spiral rod 3 is rotatably connected inside the rice sieve cylinder 2. Sealed bearings are fixedly fitted at both ends of the spiral rod 3. The outer walls of the two sealed bearings are fixedly connected to the conveying pipe 1. Centrifugal blocks 4 are installed at both ends of the spiral rod 3. Fastening bolts are threaded onto both ends of the spiral rod 3, making it a detachable connection. One side of each of the two fastening bolts abuts against the two centrifugal blocks 4, used to limit and fix the two centrifugal blocks 4. A feed pipe is sealed to one end of the rice sieve cylinder 2, and one end of the feed pipe passes through the conveying pipe 1 and is equipped with a solenoid valve 5. A rice discharge pipe 6 is sealed to the other end of the rice sieve cylinder 2. A waste discharge pipe 7 is sealed to the bottom of the conveying pipe 1. A connecting flange is provided at one end of the waste discharge pipe 7, the rice discharge pipe 6, and the feed pipe, and connects to a flexible hose and other equipment. The conveying pipe 1 is equipped with... Three support plates 8 are provided. One of the support plates 8 is fixedly connected to a fixed plate 1 on one side. A control panel 11 and a drive mechanism are fixedly installed on the fixed plate 1. The drive mechanism is connected to the control panel 11, the screw rod 3, and the discharge pipe 7. Under the drive control of the motor 12 through the preset program in the control panel 11, the screw rod 3 can rotate and drive the two centrifugal blocks 4 to rotate and act on the rice sieve cylinder 2. This achieves the effect of conveying and vibrating the rice at the same time, improving convenience and efficiency. At the same time, the industrial vacuum cleaner 15 is driven and controlled by the preset program in the control panel 11. The design of the conveying pipe 1, the discharge pipe 7, the corresponding hose, and the air inlet 16 can achieve the effect of sucking up and collecting the impurities and dust generated by the rice sieve, improving product quality and convenience.

[0030] See attached document Figures 1-3Each of the three support plates 8 has a sliding groove, and each of the three sliding grooves has a transmission plate 9 slidably connected to it. The three transmission plates 9 are fixedly sleeved on the conveying pipe 1. The solenoid valve 5 is connected to the control panel 11. The opening and closing of the solenoid valve 5 is controlled by the preset program in the control panel 11. The opening and closing frequency of the solenoid valve 5 changes with the rotation speed of the motor 12. Through the cooperation between the three support plates 8 and the three transmission plates 9, the conveying pipe 1 can vibrate up and down. Each of the three transmission plates 9 has a spring 10 fixedly installed at the bottom. One end of each of the three springs 10 is fixedly connected to the three support plates 8. The elastic potential energy generated when the three springs 10 are stretched or compressed consumes the vibration energy and avoids violent shaking of the equipment. All three springs 10 are composite springs.

[0031] See attached document Figure 1 , Figure 5 and Figure 6 The drive mechanism includes a motor 12, a transmission rod 13, a sleeve 14, and an industrial vacuum cleaner 15. The motor 12 is fixedly mounted on a fixed plate and connected to a control panel 11. The speed of the motor 12 can be adjusted via a preset program in the control panel 11. The output end of the motor 12 is fixedly connected to the transmission rod 13, and the sleeve 14 is slidably fitted onto the transmission rod 13 for transmission. A groove is formed on the inner side of the sleeve 14, and a protrusion is slidably connected within the groove. The protrusion is fixedly mounted on one end of the transmission rod 13. Through the interaction between the protrusion and the groove, the transmission rod 13 drives the sleeve 14 to rotate. The rotating effect is achieved by a universal ball movably mounted on one side of the protrusion, which contacts and connects with the sleeve to reduce friction. A reinforcing plate is movably mounted on the sleeve 14, and the reinforcing plate is fixedly connected to the corresponding support plate 8 to improve stability. A bevel gear one is fixedly connected to one end of the sleeve 14, and a bevel gear two is meshed on the bevel gear one. One side of the bevel gear two is fixedly connected to one end of the screw rod 3 for transmission and is a detachable connection. An L-shaped plate is rotatably mounted on the sleeve 14, and one end of the L-shaped plate is rotatably connected to the screw rod 3 and is a detachable connection. The L-shaped plate prevents the phenomenon of slippage between the bevel gear one and the bevel gear two.

[0032] See attached document Figure 1 An industrial vacuum cleaner 15 is fixedly installed on a fixed plate. One end of the industrial vacuum cleaner 15 is sealed with a hose, and the other end of the hose is sealed with a discharge pipe 7. The industrial vacuum cleaner 15 is connected to a control panel 11. The industrial vacuum cleaner 15 is driven and controlled by a preset program in the control panel 11. The design of the conveying pipe 1, the discharge pipe 7, the corresponding hose, and the air inlet 16 enables the collection of impurities and dust generated by rice sieving, thereby improving product quality and convenience.

[0033] See attached document Figure 4One end of the conveying pipe 1 is provided with an air inlet 16. The air inlet 16 allows the cavity outside the conveying pipe 1 to enter the conveying pipe 1. The resulting airflow pushes the debris and dust accumulated on the bottom plate of the conveying pipe 1 toward the discharge pipe 7, thus facilitating the industrial vacuum cleaner 15 to pick up the debris and dust. There is a gap between one side of each of the two centrifugal blocks 4 and the conveying pipe 1 to prevent the centrifugal blocks from blocking the air inlet 16. A filter screen is installed inside the air inlet 16 and is detachably connected. The filter screen prevents external debris from clogging the air inlet 16.

[0034] Working principle: When in use, first connect the power supply and drive and regulate the motor 12, industrial vacuum cleaner 15 and solenoid valve 5 through the preset program in the control panel 11.

[0035] First, a hose is sealed and connected to one end of the feed pipe and the rice discharge pipe 6, and one end of the two hoses is connected to the feed pipe and the storage bin respectively. Then, the motor 12 is started and the solenoid valve 5 is opened and closed intermittently. At this time, the intermittent opening and closing of the solenoid valve 5 can achieve the effect of intermittently conveying rice into the rice sieve cylinder 2, so that there is enough space in the rice sieve cylinder 2 to make the rice vibrate.

[0036] Meanwhile, the transmission rod 13 is driven by the motor 12 to rotate, and the interaction between the protrusion and the groove causes the transmission rod 13 to drive the sleeve 14 to rotate on the reinforcing plate and the L-shaped plate. At the same time, the sleeve 14 is driven by the meshing transmission between bevel gear one and bevel gear two, so that the spiral rod 3 rotates inside the rice sieve cylinder 2. At this time, the rice can be transported by the correspondence between the spiral plate and the rice sieve cylinder 2.

[0037] At the same time, the screw rod 3 drives the two centrifugal blocks 4 to rotate. At this time, through the action of the two centrifugal blocks 4, the conveying pipe 1 vibrates up and down. Meanwhile, the conveying pipe 1 drives the three transmission plates 9 to slide up and down on the three support plates 8 respectively, and causes the three springs 10 to pull or compress the rope. With the cooperation of the rice sieve cylinder 2, the rice is vibrated and screened.

[0038] At the same time, through the action of the industrial vacuum cleaner 15 and the cooperation of the hose and the waste discharge pipe 7, the impurities screened out by the rice sieve cylinder 2 and the dust generated during the rice screening process can be sucked up and collected, thereby achieving the effect of convenient collection and treatment of impurities and avoiding dust from affecting the surrounding environment.

[0039] Finally, through the cooperation between the screw rod 3 and the rice sieve cylinder 2, the screened rice is transported to the storage bin through the rice discharge pipe 6 and the corresponding flexible tube.

[0040] The technological advancements of this invention compared to existing technologies are as follows: through the cooperation of various components, not only can the rice be vibrated and screened, but the rice can also be conveyed, improving convenience and efficiency. It also facilitates the collection of screened impurities and prevents dust from affecting the surrounding environment. Furthermore, the structure is simple and more practical.
