Description

Technical Field

[0001] This utility model relates to the field of rice milk processing technology, and in particular to an automatic water inlet device for rice milk processing. Background Technology

[0002] Rice milk is made from rice, unlike soy milk. When processing rice into rice milk, the rice needs to be mixed and crushed with water. However, existing automatic water feeding devices for rice milk processing only use a water level sensor and an external controller to automatically control the water intake. The processing of rice and water is achieved by stirring and crushing.

[0003] According to the search, a Chinese patent number CN220158136U describes an automatic water feeding device for rice slurry processing, which includes a shell, a processing box fixedly connected to the upper part of the shell, a rotating column rotatably connected to the inside of the processing box, blades fixedly connected at equal intervals to the outside of the rotating column, a partition fixedly connected to the lower part of the processing box, a first feeding port equidistantly opened inside the partition, and a sieve plate fixedly connected to one side of the bottom of the processing box.

[0004] However, the automatic water feeding device for rice slurry processing mentioned above still has shortcomings. The amount of water fed in automatically is proportional to the amount of rice to form rice slurry. However, it is inconvenient to precisely control the amount of water fed in based on the amount of rice added, which makes it impossible to grind the water and rice into rice slurry in a certain proportion, thus reducing the quality of rice slurry production. In addition, the sieve plate is inconvenient to shake and screen, making the sieve plate easy to clog and reducing the screening effect and efficiency. Therefore, we propose an automatic water feeding device for rice slurry processing to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an automatic water inlet device for rice slurry processing. It can precisely control the amount of water added according to the amount of rice added, so that the water and rice are crushed into rice slurry in a certain ratio, ensuring the quality of rice slurry production. The screen plate can be shaken up and down to avoid screen plate blockage and reduce the screening effect and efficiency. Furthermore, the stirring of the stirring plate makes it easier to discharge the residual rice grains after screening.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an automatic water feeding device for rice slurry processing, comprising a processing box, a rice feeding pipe fixedly connected to the top of the processing box, a rice quantitative adding mechanism provided above the rice feeding pipe and the processing box, a quantitative water feeding mechanism provided at the top of the processing box, a controller fixedly connected to one side of the processing box, a guide plate fixedly connected to the north and south sides of the processing box, a discharge pipe fixedly connected to the bottom of the guide plate, a solenoid valve provided on the discharge pipe, a screen plate movably arranged inside the processing box, a vibrating screen mechanism provided between the screen plate and the processing box, a collection box slidably sleeved inside the processing box, a servo motor fixedly connected to the other side of the processing box, a horizontal shaft fixedly connected to the output shaft of the servo motor, and several crushing blades fixedly connected to the outer side of the horizontal shaft.

[0007] A further feature of this invention is as follows: the rice quantitative addition mechanism includes four weighing sensors fixedly connected to the top of the processing box; a support plate is fixedly connected to the top of the four weighing sensors; a rice cylinder is fixedly connected to the top of the four support plates; an electric push rod is fixedly connected to one side of the right support plate; a feeding pipe is fixedly connected to the bottom of the rice cylinder; a baffle is fixedly connected to the output shaft of the electric push rod; the baffle movably abuts against the bottom end of the feeding pipe; a stirring motor is fixedly connected to the top of the rice cylinder; a stirring shaft is fixedly connected to the output shaft of the stirring motor; stirring rods are fixedly connected to both sides of the stirring shaft; an auger is fixedly sleeved on the outside of the stirring shaft; the auger is located inside the feeding pipe; and the stirring motor, electric push rod, and weighing sensors are all electrically connected to the controller.

[0008] By adopting the above technical solution, rice is fed into the rice container. Four weighing sensors measure the overall weight of the rice container. The amount of rice to be added is determined by the controller, which activates the electric push rod and stirring motor. The electric push rod moves the baffle to the right without blocking the feeding pipe. The stirring motor drives the stirring shaft and stirring rod to rotate, thus stirring the rice to improve its fluidity and prevent blockage. At the same time, the stirring shaft drives the auger to rotate, which evenly and smoothly conveys the rice downward into the rice inlet pipe. As the rice flows into the processing box, the overall weight of the rice container decreases. When the original weight minus the current weight equals the set value, the specified weight of rice is added.

[0009] A further feature of this invention is that an adding tube is fixedly connected to the top of the rice container.

[0010] By adopting the above technical solution, it is convenient to add rice.

[0011] A further feature of this invention is that the quantitative water inlet mechanism includes a water pump fixedly connected to the top of the processing box, a water inlet pipe fixedly connected to one side of the water pump, a control valve and a flow meter installed on the water inlet pipe, the water pump, the control valve and the water pump being electrically connected to the controller, a water supply pipe fixedly connected to the other side of the water pump, and a flange fixedly connected to one end of the water supply pipe.

[0012] By adopting the above technical solution, the controller calculates the required amount of water based on the weight of the rice. Then, the controller opens the water pump and control valve to pump clean water into the water supply pipe and inlet pipe, which eventually enters the processing tank. The flow meter measures the water volume. When the specified water inlet is opened, the flow meter sends a signal to the controller, which then closes the water pump and control valve. This allows for precise control of the water inlet based on the amount of rice added, ensuring that the water is stirred and broken into rice paste according to a certain closed-loop mechanism, thus guaranteeing the quality of the rice paste.

[0013] A further feature of this invention is that the actuating vibrating screen mechanism includes a drive motor fixedly connected to the front side of the processing box, two rotating rollers rotatably connected to the inner walls of the front and rear sides of the processing box, and four ear plates. The four ear plates are respectively fixedly connected to the inner walls of both sides of the processing box. A spring is fixedly connected to the top of each ear plate, and the top ends of the four springs are fixedly connected to the bottom of the screen plate. The output shaft of the drive motor is fixedly connected to the front end of the corresponding rotating roller. A pulley is fixedly connected to the rear end of each of the two rotating rollers, and the same belt is driven through the two pulleys. Several actuating plates are fixedly connected to the outer side of each rotating roller, and the corresponding actuating plates movably abut against the top of the screen plate.

[0014] By adopting the above technical solution, rice slurry can be screened through the screen plate, and broken rice residue can be screened out. At the same time, the drive motor drives the rotation of a rotating roller, which in turn drives the rotation of two rotating rollers through the transmission of pulleys and belts. The rotating rollers drive multiple actuating blades to intermittently press down on the screen plate. Under the elastic force of the spring, the screen plate moves up and returns to its original position, thus forming the up and down reciprocating swaying of the screen plate. This avoids the screen plate from clogging and reducing the screening efficiency and effect. At the same time, under the actuation of the actuating blades, broken rice residue can be quickly pushed to the lower right and discharged from the impurity outlet.

[0015] A further feature of this invention is that two inclined plates are fixedly connected to the bottom of the screen plate, and a waste outlet is fixedly connected to one side of the processing box, the waste outlet corresponding to the screen plate.

[0016] By adopting the above technical solution, it is convenient to discharge broken rice residue, and at the same time, the rice slurry can be guided to completely enter the collection box.

[0017] A further feature of this invention is that a telescopic rod is fixedly connected between the ear plate and the screen plate, and the spring is sleeved on the outside of the telescopic rod.

[0018] By adopting the above technical solution, it is convenient to guide the spring and the screen plate, making their lifting and lowering more stable.

[0019] The beneficial effects of this utility model are:

[0020] 1. This utility model involves feeding rice into a rice container. Four weighing sensors measure the overall weight of the rice container. The required amount of rice is added. A controller activates an electric push rod and a stirring motor. The electric push rod moves a baffle to the right without blocking the feeding pipe. The stirring motor rotates the stirring shaft and stirring rod, thus stirring the rice to improve its flowability and prevent blockage. Simultaneously, the stirring shaft drives the auger to rotate, ensuring the rice is evenly and smoothly conveyed downwards into the rice inlet pipe. As the rice flows into the processing box, the overall weight of the rice container decreases. When the original weight minus the current weight equals a set value, the specified weight of rice is added.

[0021] 2. This utility model calculates the required amount of water based on the weight of the rice using a controller. The controller then opens the water pump and control valve to draw clean water into the water supply pipe and inlet pipe, ultimately entering the processing tank. The flow meter measures the water volume. When the specified water inlet is opened, the flow meter sends a signal to the controller, which then closes the water pump and control valve. This allows for precise control of the water inlet based on the amount of rice added, ensuring that the water is stirred and broken into rice paste according to a specific closed-loop mechanism, thus guaranteeing the quality of the rice paste.

[0022] 3. This utility model uses a screen plate to screen rice slurry, removing broken rice residue. Simultaneously, a drive motor rotates a roller, which, through a pulley and belt, drives two rollers to rotate. The rollers drive multiple actuating blades to intermittently press down on the screen plate. Under the elastic force of a spring, the screen plate moves back up to its original position, thus creating a reciprocating up-and-down swaying motion of the screen plate. This prevents the screen plate from clogging and reducing the efficiency and effect of screening. At the same time, the actuating blades quickly push broken rice residue to the lower right and discharge it from the impurity outlet. Attached Figure Description

[0040] In this invention, rice is fed into the rice container 61. Four weighing sensors 64 measure the overall weight of the rice container 61. The required amount of rice is added. The controller 5 activates the electric push rod 62 and the stirring motor 69. The electric push rod 62 moves the baffle 63 to the right without blocking the feeding pipe 60. The stirring motor 69 drives the stirring shaft 66 and stirring rod 68 to rotate, thus stirring the rice to improve its flowability and prevent blockage. Simultaneously, the stirring shaft 66 drives the auger 67 to rotate, ensuring the rice is evenly and smoothly conveyed downwards into the rice inlet pipe 8. As the rice flows into the processing box 1, the rice container 61... 1. The overall weight is reduced.

Thus, the water volume can be precisely controlled according to the amount of rice added, so that it is stirred and broken into rice paste according to a certain closed loop, thereby ensuring the quality of the rice paste.

[0041] The servo motor 9 drives the horizontal shaft 11 and the crushing blade 10 to rotate, thereby mixing and crushing rice and water into rice paste. After the rice paste is crushed, the solenoid valve 12 is opened, and the rice paste can be screened through the screen plate 408 to remove broken rice residue. At the same time, the drive motor 401 drives the rotation of a roller 402. Under the transmission of the pulley 410 and the belt 409, the two rollers 402 are driven to rotate. The rollers 402 drive multiple actuating plates 403 to intermittently press down on the screen plate 408. Under the elastic force of the spring 406, the screen plate 408 moves up and returns to its original position, thus forming the up and down reciprocating swaying of the screen plate 408. This prevents the screen plate 408 from clogging and reducing the efficiency and effect of screening. At the same time, under the actuation of the actuating plates 403, the broken rice residue can be quickly pushed to the lower right and discharged from the impurity outlet 3.
