Description

A rice feeding device Technical Field

[0001] This application relates to the technical field of rice feeding devices, and in particular to a rice feeding device. Background Technology

[0002] In the rice production process, the rice needs to be bagged and weighed. Usually, the staff pours the rice to be processed into the feeding device, and then weighs and bags it by controlling the amount of material fed in, so as to achieve quantitative packaging.

[0003] In related technologies, the feeding device includes a feeding mechanism, a mixing mechanism, and a discharging mechanism. The feeding mechanism is used to transport rice into the equipment, the mixing mechanism mixes various types of rice by rotation, and the discharging mechanism is used to discharge the mixed rice into bags.

[0004] Traditional rice feeding devices are limited to basic conveying operations and cannot accurately mix different types of rice by weight in actual production. When a specific ratio of mixed rice needs to be prepared, workers have to manually weigh each type of rice and then add them in sequence for mixing. This is not only cumbersome but also prone to errors due to reliance on experience, making it difficult to guarantee the accuracy and stability of the ratio. It also significantly increases labor costs and intensity. Summary of the Invention

[0005] In order to improve the problem that the lack of real-time weighing function in the feeding device requires manual weighing when mixing different types of rice, this application provides a rice feeding device.

[0006] This application provides a rice feeding device, which adopts the following technical solution: A rice feeding device includes a feeding mechanism for conveying rice to the next process. The feeding mechanism has multiple collection chambers for placing different types of rice. The outlets of the multiple collection chambers are the same size. A baffle is slidably connected to the opening of each collection chamber. The baffle is used to prevent rice from continuing to enter the next process. The baffle is provided with a control component, which is used to drive the baffle to block the outlet of the collection chamber after a set time.

[0007] By adopting the above technical solution, and by setting multiple independent collection chambers in the feeding mechanism, it is possible to simultaneously accommodate and process multiple different types of rice. Since the outlets of the multiple collection chambers are of the same size, and the baffles are equipped with control components to control the baffles to block the outlets of the collection chambers after a set time, the operators can set the corresponding time parameters for the control components to automatically control the feeding time of each collection chamber. Since the outlet size of each collection chamber is the same, the output per unit time is consistent. Therefore, by controlling the feeding time, different types of rice can be accurately mixed in a set ratio, eliminating the tedious step of manual weighing, reducing the labor intensity and error of manual operation, and realizing the intelligent and efficient feeding process.

[0008] Optionally, a weighing mechanism is also included, located between the feeding mechanism and the stirring mechanism. The weighing mechanism has a weighing plate inside, and a weighing sensor is provided on the weighing plate for weighing the rice to be mixed. When the weight measured by the weighing sensor is less than the set weight value, the weighing sensor drives a baffle to open slightly. When the weight measured by the weighing sensor reaches the set weight value, the weighing sensor drives the baffle to completely block the outlet of the collection chamber.

[0009] By adopting the above technical solution, a weighing sensor is installed on the weighing plate to weigh the rice to be mixed, so as to realize real-time monitoring and feedback control of the weight of the rice about to enter the mixing process. When the weighing sensor detects that the current weight has not reached the preset value, it drives the baffle to open slightly, so that the rice is continuously replenished at a controllable flow rate, avoiding overloading due to excessive feeding at one time; when the weight reaches the set value, the sensor immediately drives the baffle to completely block the outlet, accurately cutting off the material supply, thereby improving the accuracy and stability of the mixing ratio, ensuring that each mixing strictly meets the preset ratio requirements, and further improving production efficiency and product quality consistency.

[0010] Optionally, the weighing mechanism is provided with a conveying channel communicating with the collection chamber. A negative pressure component is provided in the conveying channel. The negative pressure component is used to absorb rice in the weighing mechanism and convey it into the collection chamber. When the weight measured by the weighing sensor is greater than the set weight value, the negative pressure component is activated and absorbs rice into the collection chamber. When the weight measured by the weighing sensor is equal to the set weight value, the negative pressure component is deactivated.

[0011] By adopting the above technical solution, a negative pressure component is installed in the conveying channel to transport the rice in the weighing mechanism to the collection chamber. This allows the rice suction device to absorb the excess rice on the weighing plate back into the collection chamber, thereby improving the accuracy of the weighing results. This not only avoids the proportioning deviation and material waste caused by overweight, but also achieves clean recycling and reuse of rice through negative pressure conveying, further improving the accuracy and automation of the mixing process.

[0012] Optionally, the collecting chamber is spherical, and the walls of the collecting chamber are all arc surfaces. The weighing mechanism is provided with a connection port for external water access, and the negative pressure component can introduce water into the collecting chamber to clean the inner wall of the collecting chamber.

[0013] By adopting the above technical solution, the walls of the collection chamber are all curved, allowing external water to clean the inner walls of the collection chamber after entering through the connection port. This avoids the risk of rice grains or dust accumulating in corners, becoming moldy, or breeding bacteria, providing a cleaner material flow environment for rice processing. Internal maintenance can be completed without manual disassembly or the introduction of additional cleaning equipment. This not only ensures hygiene, safety, and quality control stability during the mixed processing of different batches of rice, but also avoids cross-contamination of subsequent production due to the deterioration of residual materials, thereby improving the overall service life and operational reliability of the equipment.

[0014] Optionally, a guide plate is rotatably connected inside the collection chamber, and the guide plate is located at the outlet of the conveying channel; when the negative pressure component transports rice, the guide plate is tilted towards the direction close to the baffle; when the negative pressure component transports water, the guide plate is tilted towards the cavity wall of the collection chamber on the side away from the baffle.

[0015] By adopting the above technical solution, a guide plate is rotatably connected inside the collection chamber and located at the outlet of the conveying channel to achieve dynamic adjustment of the guide plate angle. When the negative pressure component transports rice, the guide plate tilts towards the baffle, allowing the rice to fall smoothly into the predetermined area of ​​the collection chamber, avoiding uneven accumulation or backflow blockage caused by deviation in the falling direction. When the negative pressure component transports water for cleaning, the guide plate tilts towards the cavity wall on the side of the collection chamber away from the baffle, guiding the water flow along the spherical arc surface to achieve all-round cleaning of the inner wall.

[0016] Optionally, a turntable is rotatably connected to the weighing plate, and the turntable is used to drive the water in the weighing mechanism to flow so as to clean the inner wall.

[0017] By adopting the above technical solution, a turntable is rotatably connected to the weighing plate, which can drive the water to form a dynamic vortex or directional flow, thereby enhancing the scouring force of the water flow on the inner wall, the surface of the weighing plate and the area around the sensor, thus efficiently stripping away and removing residual rice grains, dust and stains.

[0018] Optionally, the connection port is connected to a hot air source; after the collection chamber and the weighing mechanism have been cleaned, hot air is introduced into the connection port to dry the residual moisture on the inner wall.

[0019] By adopting the above technical solution, and connecting a hot air source at the connection port, after the collection chamber and weighing mechanism have completed the cleaning process, the system automatically switches to introduce high-temperature drying hot air to perform all-round drying treatment on the inner walls of the spherical arc surface, weighing plate, turntable and conveying channel, etc., quickly removing residual water stains and ensuring that the inside of the equipment remains dry and clean. This not only avoids the impact on production efficiency caused by the excessive time spent on natural drying, but also effectively inhibits the microbial growth environment through thorough drying, ensuring the hygiene, safety and quality control stability of subsequent batches of rice.

[0020] Optionally, the conveying channel is equipped with an adjustment control device, which is used to control the pressure at both ends of the conveying channel.

[0021] By adopting the above technical solution and adding a control unit within the conveying channel, the pressure at both ends of the channel can be precisely controlled, thereby optimizing the airflow stability and material flow state during the negative pressure conveying process. When conveying rice, the control unit can adjust the appropriate pressure according to the material characteristics, ensuring that the rice grains pass through the channel smoothly and at a uniform speed, avoiding blockages, dust, or conveying interruptions caused by pressure fluctuations. When performing water washing and cleaning, the control unit can adjust the pressure to enhance the water flow scouring force and improve the cleaning effect. This design not only improves the reliability and efficiency of the feeding and cleaning processes but also enhances the device's adaptability to different operating conditions, providing more refined control methods for automated production.

[0022] In summary, this application includes at least one of the following beneficial technical effects: by setting multiple independent collection chambers in the feeding mechanism, it can simultaneously accommodate and process multiple different types of rice. The outlets of the multiple collection chambers are of the same size, and the baffles are equipped with control components to control the baffles to block the outlets of the collection chambers after a set time. The operator can set the corresponding time parameters for the control components to automatically control the feeding time of each collection chamber. Since the outlets of each collection chamber are of the same size, the output per unit time is consistent. Therefore, by controlling the feeding time, different types of rice can be accurately mixed in a set ratio, eliminating the tedious steps of manual weighing, reducing the labor intensity and error of manual operation, and realizing the intelligent and efficient feeding process.

[0023] The weighing plate is equipped with a weighing sensor to weigh the rice to be mixed, enabling real-time monitoring and feedback control of the rice weight before it enters the mixing process. When the weighing sensor detects that the current weight has not reached the preset value, it drives the baffle to open slightly, allowing the rice to be continuously replenished at a controllable flow rate, avoiding overloading due to excessive feeding at one time. When the weight reaches the set value, the sensor immediately drives the baffle to completely block the outlet, precisely cutting off the material supply, thereby improving the accuracy and stability of the mixing ratio, ensuring that each mixing strictly meets the preset ratio requirements, and further improving production efficiency and product quality consistency.

[0026] The present application will be further described in detail below with reference to Figures 1-5. Examples

[0027] This embodiment discloses a rice feeding device. Referring to Figure 1, a rice feeding device includes a feeding mechanism 1, which includes multiple feeding pipes 11 for conveying different types of rice into the feeding mechanism 1. The feeding mechanism 1 has multiple collection chambers 12 for placing different types of rice, and the outlet size of the multiple collection chambers 12 is the same. A baffle 121 is slidably connected to the opening of each collection chamber 12 to prevent rice from escaping from the collection chamber 12. The feeding mechanism 1 is electrically connected to a control component 13, which drives the baffle 121 to block the outlet of the collection chamber 12 after a set time.

[0028] The implementation principle of Example 1 is as follows: Different types of rice enter the corresponding collection chamber 12 through the corresponding feeding pipe 11. The operator sets the opening time of the baffle 121 in each collection chamber 12 using the control component 13 to achieve quantitative release of different types of rice, allowing them to enter the next process for mixing in proportion.

[0029] Referring to Figures 2 and 3, the difference between this embodiment and embodiment 1 is that it also includes a weighing mechanism 2, which is connected to the outlet of the feeding mechanism 1.

[0030] Referring to Figures 3 and 4, a weighing chamber 21 is provided inside the weighing mechanism 2. A weighing plate 22 is fixedly connected to the wall of the weighing chamber 21. A weighing sensor 221 is fixedly connected to the surface of the weighing plate 22 away from the collection chamber 12. The weighing sensor 221 is used to weigh the rice that is about to be mixed.

[0031] Referring to Figures 4 and 5, when the weight measured by the weighing sensor 221 is less than the set weight value, the weighing sensor 221 drives the baffle 121 to open slightly, allowing a small amount of rice to fall into the weighing chamber 21 from the opening of the baffle 121 to compensate for the missing amount of rice. When the weight measured by the weighing sensor 221 reaches the set weight value, the weighing sensor 221 drives the baffle 121 to completely block the outlet of the collecting chamber 12, preventing rice from continuing to enter the weighing chamber 21.

[0032] Referring to Figures 4 and 5, the weighing mechanism 2 has a conveying channel 23 communicating with the collection chamber 12. A negative pressure component 24 is fixedly connected to the port of the conveying channel 23 near the collection chamber 12. The negative pressure component 24 is used to absorb excess rice in the weighing chamber 21 and transport it back to the collection chamber 12. When the weight value measured by the weighing sensor 221 is greater than the set weight value, the negative pressure component 24 automatically starts and absorbs the rice in the weighing chamber 21 into the collection chamber 12, until the weight value measured by the weighing sensor 221 equals the set weight value, at which point the negative pressure component 24 shuts down.

[0033] Referring to Figures 4 and 5, the collecting chamber 12 is spherical, and the walls of the collecting chamber 12 are all curved surfaces. The weighing mechanism 2 is provided with a connection port 25 for external water access, and the negative pressure component 24 can introduce water into the collecting chamber 12 to clean the inner wall of the collecting chamber 12.

[0034] Referring to Figures 4 and 5, a guide plate 122 is rotatably connected inside the collection chamber 12, and the guide plate 122 is located at the outlet of the conveying channel 23. When the negative pressure assembly 24 conveys rice, the guide plate 122 tilts towards the baffle 121. When the negative pressure assembly 24 conveys water, the guide plate 122 tilts towards the side of the collection chamber 12 away from the baffle 121, allowing water to flow better along the inner wall of the collection chamber 12, thereby cleaning the inner wall of the collection chamber 12.

[0035] Referring to Figure 4, a turntable 26 is rotatably connected to the surface of the weighing plate 22 away from the ground. The turntable 26 is set in a circular shape. When the negative pressure device delivers water in the turntable 26 to the collection chamber 12, it can drive the turntable 26 to rotate, so that the water in the weighing chamber 21 can rotate and flow under the drive of the turntable 26, so as to clean the cavity wall of the weighing chamber 21.

[0036] Referring to Figures 4 and 5, the connection port 25 is connected to the hot air source. After the collection chamber 12 and the weighing chamber 21 have been cleaned, hot air is introduced into the connection port 25 to dry the inner walls of the collection chamber 12 and the weighing chamber 21, so as to remove the residual moisture on the inner walls.

[0037] The implementation principle of Example 2 is as follows: Different types of rice enter the corresponding collection chambers 12 from different feeding pipes 11. The opening time of each baffle 121 is set by the control component 13, and the rice falls quantitatively into the weighing chamber 21. The weighing plate 22 weighs the rice. When the weight of the rice is less than the measured value, the baffle 121 opens at a small angle. When the weight of the rice is greater than the set value, the negative pressure device is activated. The negative pressure device absorbs the rice from the weighing chamber 21 into the collection chamber 12 to achieve accurate weighing of the rice. When the staff cleans the equipment, the staff introduces water into the weighing chamber 21 through the connection port 25 and activates the negative pressure device. The negative pressure device drives the turntable 26 to rotate to drive the water flow to wash the inner wall. The water entering the collection chamber 12 washes the inner wall of the collection chamber 12 along the guide plate 122. After cleaning, the water in the equipment is discharged, and hot air is introduced through the connection port 25 to dry the inner wall of the equipment.
