Description

Technical Field

[0001] The invention relates to the technical field of material detection and separation, and in particular to a rice processing technology and a material detection and separation device. Background Art

[0002] Humidity sensors are devices that can sense changes in external humidity and convert humidity into useful signals through changes in the physical or chemical properties of the device material. Good stability, short response time, long life, interchangeability, pollution resistance, and little influence by temperature in various gas environments, miniaturization, integration, and low cost are the development direction of humidity sensors.

[0003] In recent years, with the intensification of global warming, the "El Nino" phenomenon has gradually increased, and the El Nino event has caused a significant increase in global precipitation compared to normal years. For China, El Nino is prone to warm winters, and heavy rains and floods are prone to occur in the south. The middle and lower reaches of the Yangtze River Plain and South China are the main rice planting areas in my country. However, with the frequent occurrence of extreme weather, long-term rainy weather is not conducive to the drying of rice after harvesting, and may even cause the stored rice to mold and deteriorate. Therefore, before the rice is processed into rice, it is necessary to detect the dryness and humidity of the rice, and the rice that does not meet the dryness and humidity standards needs to be further dried before subsequent processing. In the prior art, a rice humidity detector is used before rice processing to perform a small amount of multiple sampling tests on the rice. First, the humidity of all rice cannot be detected, and second, multiple manual sampling is required, which is time-consuming and labor-intensive, resulting in some rice that does not meet the humidity standards entering the processing flow. Summary of the invention

[0004] The purpose of the invention is to provide a rice processing technology and a detection and distribution device, aiming to solve the problem of inconvenience in continuous detection and distribution of rice moisture in the prior art.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: A rice processing detection and dispensing device comprises a detection bin, a humidity sensor is arranged on the top of the inner wall of the detection bin, a feeding port is provided on the detection bin, a collection box is arranged below the humidity sensor, openings are provided on the top and bottom of the collection box, a plurality of ventilation holes are provided on the inner wall of the collection box, a ventilation cavity is provided in the side wall of the collection box, a first hot air duct is provided on the collection box, two movable plates are arranged opposite to each other at the bottom of the collection box, the movable plates are hinged to the collection box, anti-fall plates are vertically arranged on both sides of the movable plates, movable rods are vertically arranged at the ends of the two movable plates close to each other, the movable rods are hinged to the movable plates, An opening and closing cylinder is arranged on the top of the movable rod, and the movable rod is hinged to the moving end of the opening and closing cylinder, a fixed plate is horizontally arranged on the inner wall of the detection bin, a pressure plate is horizontally arranged on the collection box, a pressure sensor is arranged on the top of the fixed plate, and the pressure plate is in contact with the pressure sensor, a dividing plate is arranged below the collection box, a dividing shaft is horizontally arranged on the dividing plate, a first motor is arranged on the dividing shaft, a drying box and a rotating screen drum are respectively arranged on both sides of the dividing plate, the humidity sensor is connected to the first motor and the opening and closing cylinder through a circuit, and the pressure sensor is connected to the first motor and the opening and closing cylinder through a circuit.

[0006] Through the above technical scheme, the rice is transported from the barn to the feed port, and the rice falls into the collection box from the feed port. The hot air blown out by the first hot air pipe is blown out from the ventilation hole through the ventilation cavity. If the humidity of the rice is too high, the hot air will bring the moisture on the surface of the rice upwards, triggering the humidity sensor. The humidity sensor sends an electrical signal to the first motor and the opening and closing cylinder. The first motor controls the rotation of the dividing plate, and the opening and closing cylinder controls the movable rod to move downward. The movable plate opens, and the rice falls vertically on the dividing plate and moves to the left under the guidance of the dividing plate, and falls to one side of the detection bin, collecting the rice with unqualified humidity. At this time, all the rice in the collection box is discharged, and the pressure on the pressure sensor is reduced to a minimum, sending an electrical signal to control the opening and closing of the gas cylinder. The cylinder closes the movable plate, and the collecting box collects the next wave of rice; if the humidity sensor has not been triggered, the rice in the collecting box gradually increases, and the pressure applied by the pressure plate to the pressure sensor on the fixed plate gradually increases. When the rice is loaded to a certain weight, the pressure sensor is triggered, and the pressure sensor sends an electrical signal to the first motor and the opening and closing cylinder. The first motor controls the dividing plate to turn to another direction, and the opening and closing cylinder controls the movable rod to move downward, and the movable plate opens. The rice falls vertically on the dividing plate, moves to the right under the guidance of the dividing plate, and falls into the rotating screen drum. The rotating screen drum rotates, and the rice moves toward the discharge end in the rotating screen drum. The rice with the particle size that meets the requirements is screened out by the screen holes, and the straw, leaves and other debris that are too large are screened out.

[0007] It should be understood that the structure and principle of driving the rotating screen drum are prior arts in the art and will not be elaborated in detail herein.

[0008] The present invention is further configured as follows: a friction plate is provided on the material dividing plate, the friction plate is slidably connected to the material dividing plate, connecting plates are provided on both sides of the material dividing plate, an impeller cylinder is provided between the two connecting plates, the two ends of the impeller cylinder are respectively rotatably connected to the two connecting plates, a ratchet is coaxially provided on the end face of the impeller cylinder, a pawl matching the ratchet is hinged on the end face of the impeller cylinder, a limiting rod is also provided on the end face of the impeller cylinder, the pawl is located between the ratchet and the limiting rod, a circular plate is coaxially provided on the ratchet, a spring is provided between the circular plate and the ratchet, a driving rod is hinged on the circular plate, a set distance is provided between the hinge between the driving rod and the circular plate and the center of the circular plate, and the end of the driving rod away from the circular plate is connected to the side of the movable plate.

[0009] Through the above technical scheme, when the dry rice falls, it impacts the impeller cylinder, the impeller cylinder rotates, and the ratchet rotates. At this time, the ratchet pawl conflicts with the teeth of the ratchet wheel, and the impeller cylinder can only rotate in one direction. The driving spring is tightened, and the rice slides down through the friction plate into the rotating screen cylinder. Since the circular plate drives the movable plate to move back and forth, the rice is thrown back and forth when it falls from the friction plate. The rice can be evenly thrown into the rotating screen cylinder, thereby improving the screening efficiency of the rotating screen cylinder. When the humidity sensor is triggered, the dividing plate turns to the other outside. At this time, the impeller cylinder is located below the dividing plate, and the ratchet pawl separates from the ratchet wheel under the action of gravity and contacts with the limit rod. At this time The tightened spring is loosened, the impeller cylinder begins to reverse, and the friction plate begins to move back and forth under the action of the circular plate. When the friction plate moves forward to the limit, the end of the friction plate exceeds the end of the dividing plate. At this time, the wet rice is also thrown into the drying box and distributed evenly, which is conducive to the drying of the rice. In addition, static electricity will be generated when the friction plate and the dividing plate rub against each other. Dust will be generated when the rice falls into the rotating screen cylinder or is dried in the drying box. The static electricity on the friction plate and the dividing plate will absorb part of the dust to prevent the dust from scattering. At the same time, when the impeller cylinder reverses, it will accelerate the air in the direction of the drying box to flow to the side of the dividing plate, thereby enhancing the dust suction effect.

[0010] The present invention is further configured as follows: a stirring rod is also provided in the detection chamber, a stirring plate is provided at the lower end of the stirring rod, the stirring plate is spiral-shaped, the stirring plate is located in the aggregate box, and a second motor is provided on the top of the stirring rod.

[0011] Through the above technical solution, the second motor controls the rotation of the stirring rod, and the stirring plate turns the rice in the aggregate box, thereby promoting the dissipation of moisture on the rice in the aggregate box and improving the accuracy of humidity monitoring.

[0012] The present invention is further configured as follows: the bottom of the drying box is arranged in an inclined shape, a vent is provided at the bottom of the drying box, a second hot air duct is provided at the bottom of the drying box, a discharge door is provided on the side wall of the drying box, a discharge cylinder is provided on the discharge door, the top of the drying box is open, and a conveyor belt is provided between the discharge door and the rotating screen drum.

[0013] Through the above technical scheme, when the humidity of the rice in the collecting box is too high, the rice is guided by the dividing plate and falls into the drying box. The second hot air duct uses hot air to dry the rice in the drying box. After drying for a fixed time, the unloading cylinder opens the unloading door, and the dried rice falls from the unloading door onto the conveyor belt and enters the rotating screen drum for grading and screening.

[0014] The present invention is further configured as follows: a turning rod is arranged above the drying box, a spiral turning plate is arranged at the bottom of the turning rod, and the turning rod is connected to the stirring rod through a belt.

[0015] Through the above technical scheme, the turning rod rotates under the action of the second motor, the belt and the stirring rod, driving the turning plate to rotate, thereby accelerating the drying speed of the rice. At the same time, the rice generated when the rice is turned up by the turning rod is adsorbed by the static electricity generated between the dividing plate and the friction plate.

[0016] The present invention is further configured as follows: the rotary screen drum comprises a plurality of sub-screening parts, and the screen holes on the plurality of sub-screening parts are enlarged in sequence.

[0017] Through the above technical solution, the rotary screen drum can grade and screen the rice into groups with different particle sizes, while removing large particles and impurities to facilitate the next step of processing.

[0018] The present invention is further configured as follows: a rotating rod is vertically arranged above the rotating screen drum, the rotating rod is connected to the stirring rod by a belt, knocking rods are arranged on both sides of the rotating screen drum, knocking balls are arranged at both ends of the knocking rods, fixing parts are also arranged on both sides of the rotating screen drum, the middle part of the knocking rod is hinged to the fixing part, the two knocking rods are arranged in an "eight" shape, a spring is arranged between the knocking rods, a cam is arranged between the tops of the two knocking rods, and the cam is connected to the rotating rod.

[0019] Through the above technical scheme, the rotating rod rotates driven by the second motor, the stirring rod and the belt, driving the cam to rotate, and the cam rotates between the two knocking rods. Under the action of the spring, one end of the two knocking rods is always in contact with the knocking rod. The knocking rod starts to swing, and the knocking ball at the other end knocks the surface of the rotating screen drum, which can not only promote the screening of the material in the rotating screen drum, but also prevent the screen holes from being blocked.

[0020] The present invention is further configured as follows: a fan blade is further provided in the detection chamber, the fan blade is connected to the stirring rod via a belt, the fan blade is located above the interior of the detection chamber, and the fan blade is close to the feed port.

[0021] Through the above technical solution, the fan blades rotate under the action of the belt and the stirring rod, and the gas below is pumped upward, which increases the rising speed of water vapor in the collecting box and reduces the sensing time of the humidity sensor. At the same time, the fan blades are close to the feed port, and the gas is pumped to the vicinity of the feed port by the fan blades and discharged from the feed port, which also prevents the water vapor of the external rice from emitting into the interior of the detection chamber and affecting the detection effect.

[0022] A rice processing process based on the above-mentioned rice processing detection and material separation device comprises the following steps: S1, detection and sorting: convey the rice to the detection and sorting device, detect the humidity, and screen the rice with humidity less than the set value in multiple stages, remove large particles and impurities, and then convey it to the next process. The rice with humidity greater than the set value is re-dried and screened in multiple stages; S2, wind selection: The screened rice is passed through a fan to remove light, low-quality rice grains, weeds and dry rice; S3, husking: putting the rice into a rice husking machine for husking; S4, rice-rough separation: putting the husked rice into a rice-rough separator to separate the rice from the rice; S5, rice milling: sending the rice into a rice milling machine for milling to obtain milled white rice; S6, polishing: sending the white rice into a polishing machine for polishing; S7. Packaging: weighing and packaging the polished white rice.

[0023] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention sets a humidity sensor, and hot air brings the rice in the collection box upward. If the humidity of the rice does not meet the standard, the hot air will bring out some water vapor from the rice, and the humidity sensor will be triggered. The distribution plate can be controlled to rotate. At the same time, the collection box is unloaded, and the rice that does not meet the humidity standard is discharged for subsequent processing. If the humidity sensor has not been triggered, the rice in the collection box increases and the pressure sensor is triggered. The pressure sensor controls the distribution plate to turn to the other side, and the rice with qualified humidity is introduced into the rotating screen drum by the distribution plate for the next screening process. The technology of the present invention determines whether the humidity of the rice is qualified through the humidity sensor and the pressure sensor, and can continuously detect the humidity of the rice in real time and distribute the rice, with high speed and efficiency.

[0024] 2. When the dry rice falls, it impacts the impeller cylinder, which rotates and tightens the drive spring. The rice slides down through the friction plate into the rotating screen cylinder. When the rice falls from the friction plate, it is thrown back and forth under the action of the friction plate. The rice can be evenly thrown into the rotating screen cylinder, which improves the screening efficiency of the rotating screen cylinder. When the humidity sensor is triggered, the dividing plate turns to the other side. At this time, the impeller cylinder is located below the dividing plate. The pawl is separated from the ratchet wheel under the action of gravity and contacts the limit rod. At this time, the tightened spring is loosened. The impeller cylinder starts to reverse, and the friction plate starts to move back and forth and rub under the action of the circular plate. The wet rice is thrown into the drying box and distributed evenly, which is beneficial to the drying of the rice. Static electricity is generated when the friction plate and the dividing plate rub against each other. When the rice falls into the rotating screen cylinder or is dried in the drying box, dust is generated. The static electricity on the friction plate and the dividing plate absorbs part of the dust to prevent it from scattering. At the same time, when the impeller cylinder reverses, it will accelerate the air in the direction of the drying box to flow to the side of the dividing plate, thereby enhancing the dust collection effect.

[0025] 3. The rotating screen drum will screen and grade the rice with qualified moisture content. The beating rod will hit the rotating screen drum under the action of the second motor, which can not only improve the screening effect of the rotating screen drum, but also prevent the screen holes on the rotating screen drum from being blocked.

[0026] 4. The present invention provides a drying box, and the dividing plate guides the rice with unqualified humidity into the drying box. The second hot air duct heats and dries the rice. At the same time, the turning plate turns the rice under the action of the second motor to promote the drying of the rice. After drying for a certain period of time, the unloading cylinder opens the unloading door, and the dried rice falls from the unloading door onto the conveyor belt and enters the rotating screen drum for grading and screening. 5. The present invention arranges fan blades to draw the gas from below upward, thereby increasing the rising speed of water vapor in the collecting box and reducing the sensing time of the humidity sensor. At the same time, the fan blades are close to the feed port, and the gas is drawn to the vicinity of the feed port by the fan blades and discharged from the feed port, which also prevents the water vapor of the external rice from emitting into the interior of the detection chamber and affecting the detection effect.

[0027] 6. The present invention uses the driving structure of the second motor to realize the turning of the rice in the collecting box, thereby improving the detection accuracy and efficiency. It can drive the knocking rod to knock the rotating screen cylinder to prevent blockage, and at the same time drive the turning plate to rotate to accelerate the drying of the rice being dried. It can also drive the fan blades to rotate to promote the rise of water vapor in the detection chamber and prevent external water vapor from entering, thereby achieving multiple effects.

[0036] A rice processing process of a rice processing detection and material distribution device comprises the following steps: S1, detection and sorting: convey the rice to the detection and sorting device, detect the humidity, and screen the rice with humidity less than the set value in multiple stages, remove large particles and impurities, and then convey it to the next process. The rice with humidity greater than the set value is re-dried and screened in multiple stages; S2, wind selection: The screened rice is passed through a fan to remove light, low-quality rice grains, weeds and dry rice; S3, husking: putting the rice into a rice husking machine for husking; S4, rice-rough separation: putting the husked rice into a rice-rough separator to separate the rice from the rice; S5, rice milling: sending the rice into a rice milling machine for milling to obtain milled white rice; S6, polishing: sending the white rice into a polishing machine for polishing; S7. Packaging: weighing and packaging the polished white rice.

[0037] The workflow of this technical solution is as follows: The rice is transported from the barn to the feed port 3, and the rice falls into the collection box 4 from the feed port 3. The second motor 29 controls the stirring rod 27 to rotate, and the stirring plate 28 turns the rice in the collection box 4 to promote the dissipation of moisture on the rice in the collection box 4. The hot air blown out by the first hot air pipe 5 is blown out from the ventilation hole 4a through the ventilation cavity 4b. If the humidity sensor 2 has not been triggered, the rice in the collection box 4 gradually increases, and the pressure applied by the pressure plate 11 to the pressure sensor 12 on the fixed plate 10 gradually increases. When the rice is loaded to a certain weight, the pressure sensor 12 is triggered, and the pressure sensor 12 sends an electrical signal to the first motor 15 and the opening and closing cylinder 9. The first motor 15 controls the dividing plate 13 to turn to the right, and the opening and closing cylinder 9 controls The movable rod 8 moves downward, the movable plate 6 opens, and the rice falls downward, impacting the impeller cylinder 20. The impeller cylinder 20 rotates, and the ratchet 21 rotates. At this time, the pawl 22 conflicts with the teeth of the ratchet 21, and the impeller cylinder 20 can only rotate in one direction. The driving spring 25 is tightened, and the rice slides down through the friction plate 18 into the rotating screen cylinder 17. Since the circular plate 24 drives the movable plate 6 to move forward and backward, the rice is thrown forward and backward when falling from the friction plate 18. The rice can be evenly thrown into the rotating screen cylinder 17, thereby improving the screening efficiency of the rotating screen cylinder 17. The rotating screen cylinder 17 rotates, and the rice moves toward the discharging end in the rotating screen cylinder 17. The rice with the particle size meeting the requirements is screened out by the screen holes, and the straw, leaves and other debris with too large volume are screened out; When the humidity of the rice does not meet the standard and the humidity sensor 2 is triggered, the dividing plate 13 turns to the left. At this time, the impeller cylinder 20 is located below the dividing plate 13. The pawl 22 is separated from the ratchet 21 under the action of gravity and contacts the limit rod 23. At this time, the tightened spring 25 is loosened, the impeller cylinder 20 starts to reverse, and the friction plate 18 starts to move back and forth under the action of the circular plate 24. When the friction plate 18 moves forward to the limit, the end of the friction plate 18 exceeds the end of the dividing plate 13. At this time, the wet rice is also thrown into the drying box 16 and evenly distributed. 16b blows out hot air, and the turning plate 31 turns the wet rice, which is conducive to the drying of the rice. In addition, static electricity will be generated when the friction plate 18 and the dividing plate 13 rub against each other. When the rice falls into the rotating screen drum 17 or is dried in the drying box 16, dust will be generated. The static electricity on the friction plate 18 and the dividing plate 13 adsorbs part of the dust to prevent the dust from scattering. At the same time, the impeller drum 20 is reversed under the action of the spring 25 when it is located below the dividing plate 13. The reversal of the impeller drum 20 will accelerate the air in the direction of the drying box 16 to flow to the side of the dividing plate 13, thereby enhancing the dust absorption effect. After drying for a certain period of time, the unloading cylinder 16d controls the unloading door 16c to open, and the dried rice enters the rotating screen drum 17 for screening through equipment such as a conveyor belt.

[0038] The rotating rod 32 is driven by the second motor 29, the stirring rod 27 and the belt to rotate, driving the cam 37 to rotate. The cam 37 rotates between the two knocking rods 33. Under the action of the spring 36, one end of the two knocking rods 33 is always in contact with the knocking rod 33. The knocking rod 33 starts to swing, and the knocking ball 34 at the other end knocks the surface of the rotating screen drum 17, which can not only promote the screening of the material in the rotating screen drum 17, but also prevent the screen hole from being blocked. The fan blades 38 rotate under the action of the belt and the stirring rod 27, and the gas below is pumped upward, increasing the rising speed of the water vapor in the collecting box 4 and reducing the sensing time of the humidity sensor 2. At the same time, the fan blades 38 are close to the feed port 3, and the gas is pumped to the vicinity of the feed port 3 by the fan blades 38 and discharged from the feed port 3, which also prevents the water vapor of the external rice from emitting into the inside of the detection chamber 1 and affecting the detection effect.

[0039] The present technical scheme is provided with a humidity sensor 2, and the hot wind brings the rice in the collecting box 4 upward. If the humidity of the rice does not meet the standard, the hot wind will bring out a part of the water vapor from the rice, and the humidity sensor 2 is triggered, which can control the distribution plate 13 to rotate, and at the same time the collecting box 4 is unloaded, and the rice that does not meet the humidity standard is discharged for subsequent processing. If the humidity sensor 2 has not been triggered, the rice in the collecting box 4 is increasing, and the pressure sensor 12 is triggered. The pressure sensor 12 controls the distribution plate 13 to turn to the other side, and the rice with qualified humidity is introduced into the rotating screen drum 17 by the distribution plate 13 for the next step of screening and processing. The technology of the present invention determines whether the humidity of the rice is qualified by the humidity sensor 2 and the pressure sensor 12, and can continuously detect the humidity of the rice in real time and distribute the materials, which is fast and efficient. The friction plate 18 starts to move back and forth and rub under the action of the circular plate 24, so as to achieve the function of throwing the rice. The wet rice is thrown into the drying box 16 and evenly distributed, which is conducive to the drying of the rice. The dry rice is thrown into the rotating screen drum 17 to enhance the screening effect. The friction plate 18 and the dividing plate 13 are made of nylon and glass respectively, so that static electricity is generated when the friction plate 18 and the dividing plate 13 rub against each other. When the rice falls into the rotating screen drum 17 or is dried in the drying box 16, dust is generated. The static electricity on the friction plate 18 and the dividing plate 13 absorbs part of the dust to prevent the dust from scattering. At the same time, when the impeller cylinder 20 is reversed, it will accelerate the air in the direction of the drying box 16 to flow to the side of the dividing plate 13, thereby enhancing the dust absorption effect. Through the driving structure of the second motor 29, the rice in the collecting box 4 can be turned over, thereby improving the detection accuracy and efficiency. The knocking rod 33 can be driven to knock the rotating screen drum 17 to prevent blockage. At the same time, it can drive the turning plate 31 to rotate to accelerate the drying of the rice being dried, and can also drive the fan blades 38 to rotate to promote the rise of water vapor in the detection chamber 1 to prevent external water vapor from entering, thereby achieving multiple effects.
