Description

Technical Field

[0001] This utility model belongs to the field of rice hulling technology, specifically relating to an intelligent rice milling machine. Background Technology

[0002] Because rice retains its intact husk and bran layer, it can effectively isolate itself from air, moisture, and microorganisms, allowing it to be stored for 1 to 2 years. Rice, on the other hand, loses its protective layer after processing, with the endosperm directly exposed, making it prone to moisture absorption and oxidation. It can usually only be stored for 6 to 12 months. Furthermore, because rice loses its protective layer, its fats are easily oxidized and rancid, leading to staleness and off-flavors.

[0003] Currently, all rice sold on the market is hulled rice, and its taste deteriorates after prolonged storage. Although some rice is vacuum-packed, the starch gradually retrogrades during storage, causing cold rice to harden and become dry.

[0004] Furthermore, the inventors have discovered that existing rice milling equipment does not have a rice milling weighing mechanism. Therefore, existing rice milling equipment is temporarily unable to mill the corresponding amount of rice according to the customer's required amount of rice. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an intelligent rice milling machine that can mill rice on demand and with controllable weight.

Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions of this utility model will be clearly and completely described below in conjunction with the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments in this application. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0021] Example 1: like Figures 1 to 21As shown, this disclosure presents an intelligent rice milling machine, comprising a body 1, a grain storage bin 6, a screw conveyor 28, a rice huller 30, an outlet pressure regulating mechanism 31, a rice receiving bin 12, an outlet guide chute 10, a rice unloading mechanism 16, a rice milling drive motor 49, a main control board 63, and an intelligent control screen 7. At least one first weighing device 23 is installed on each of the symmetrical sides of the grain storage bin 6, and is stably mounted on the body 1 via the first weighing devices 23. The screw conveyor 28 has an inlet end and an outlet end, is installed at the bottom of the grain storage bin 6, and the inlet end is connected to the grain storage bin 6. The rice huller 30 has a grain inlet, a bran outlet, and a rice outlet. The grain inlet is connected to the outlet end of the screw conveyor 28, and the bran outlet is connected to the rice milling exhaust fan 13. The outlet pressure regulating mechanism 31 is installed at the rice outlet of the rice huller 30 and is used to regulate the pressure at the rice outlet. The rice receiving hopper 12 has an inverted conical structure with a rice discharge port at the bottom. Two second weighing sensors 47 are symmetrically installed on the hopper, and the two second weighing sensors 47 are stably mounted on the machine body 1. One end of the outlet guide chute 10 is installed at the bottom of the rice discharge port, and the other end extends to the rice receiving hopper 12. One end of the rice unloading mechanism 16 is installed in the rice receiving hopper 12, and the other end can be adjusted to seal the rice discharge port. The rice milling drive motor 49 is installed on the machine body 1 and is connected to the rice huller 30. The rice huller 30 is connected to the rice milling exhaust fan 13. The main control board 63 is electrically connected to the intelligent control screen 7, the first weighing device 23, the screw conveyor 28, the rice huller 30, the rice milling exhaust fan 13, the outlet pressure regulating mechanism 31, the second weighing sensors 47, the rice unloading mechanism 16, and the rice milling drive motor 49.

[0022] The rice milling drive motor 49 and the rice huller 30 can be connected via a transmission component 42, and the rice huller 30 and the rice milling exhaust fan 13 can be connected via another transmission component 42. The transmission component can be a transmission belt. Accordingly, the rice milling drive motor 49, the rice huller 30, and the rice milling exhaust fan 13 are all equipped with pulleys.

[0023] It should be noted that the rice milling drive motor 49, the rice huller 30, and the rice milling exhaust fan 13 are all commonly used existing rice milling equipment. The transmission connection between the rice milling drive motor 49 and the rice huller 30, and between the rice huller 30 and the rice milling exhaust fan 13, can be a commonly used transmission connection method. The bran discharge port 3001 of the rice huller 30 is connected to the rice milling exhaust fan 13, and the rice milling exhaust fan 13 extracts the bran powder generated inside the rice huller 30 through the bran discharge port 3001.

[0024] like Figure 2-5 As shown, the outlet end of the screw conveyor 28 is connected to the inlet end of the rice huller 30 via a guide hopper 29. The screw conveyor 28 pushes the rice in the storage bin to the outlet end, and then the rice falls into the guide hopper 29 through the outlet end, and then into the rice huller 30 through the guide hopper 29.

[0025] like Figure 1-6As shown, the grain storage bin 6 includes a hollow square body and an inverted, hollow isosceles trapezoid. The square body is installed on the top of the isosceles trapezoid, and the top and bottom surfaces of the isosceles trapezoid and the square body are open.

[0026] like Figure 3 As shown, the rear and front ends of the machine body 1 are each equipped with a second support rod 41, which is used to support the installation of the first weighing device 23. Further, this embodiment provides one installation method for the first weighing device: two first weighing devices are installed at intervals on the second support rod at the rear end, and one first weighing device is installed on the second support rod at the front end, with the three first weighing devices arranged in a triangular distribution. The three first weighing devices jointly support the grain storage silo 6, and the weighing data is transmitted to the intelligent control screen in real time.

[0027] like Figure 18 As shown, the first weighing device 23 includes a first weighing sensor 232 and a support plate 231. The top of the support plate 231 is bent to form a second inclined end 235, and the bottom is provided with a first horizontal plate 233. The end of the first horizontal plate 233 away from the support plate 231 is bent to form a first inclined end 234. The first inclined end 234 and the second inclined end 235 are both in contact with an isosceles trapezoid.

[0028] Understandably, the first weighing sensor 232 is electrically connected to the main control board 63. The weight information monitored by the first weighing sensor is transmitted to the main control board. After receiving the weight information, the main control board analyzes and processes it, and then displays it on the intelligent control screen, thus facilitating the determination of the weight of rice in the grain storage bin. For example, in this embodiment, three first weighing devices are installed. The weight data obtained by the three first weighing sensors from monitoring the grain storage bin is transmitted to the main control board. After receiving the weight information, the main control board analyzes and processes it, and then displays the sum of the measurement data from the three first weighing sensors on the intelligent control screen, which is the total amount of rice in the grain storage bin.

[0029] like Figure 1-6 As shown in Figure 16, the body 1 has a square structure, including a square frame, a left side panel, a right side panel, a rear panel and a door 3. The left side panel is installed on the left side of the square frame, the right side panel is installed on the right side, the rear panel is installed at the rear end, and the door 3 is installed at the front end.

[0030] A locking connection structure between the door 3 and the body is provided, with an additional T-type lock 8 installed. The door 3 is installed at the front end of the body 1. Both ends of one side of the door 3 are rotatably connected to the body 1, and the other side is locked to the body 1 by the T-type lock 8. The door 3 has a rice dispensing port 3031 at the bottom corresponding to the rice receiving compartment 12.

[0031] To enhance the function of the rice dispensing opening, a rice dispensing window frame 18 is installed on the rice dispensing opening 3031, and a rice dispensing window 181 is provided on the rice dispensing window frame 18 corresponding to the rice dispensing opening 3031. The rice dispensing window 181 is aligned and communicates with the rice dispensing opening 3031, so as to facilitate the retrieval of rice unloaded from the rice receiving compartment.

[0032] like Figure 2 , 5 As shown in Figure 17, a rotating connection structure between the machine door and the machine body is provided. A door frame bearing 25, a rotating shaft 26 and a connecting plate 24 are added. The door frame bearing 25 is installed on the door frame 302 of the machine door 3. The door frame bearing 25 is provided with a rotating shaft 26. One end of the connecting plate 24 is installed on the machine body 1, and the other end is sleeved on the rotating shaft 26. The rotating shaft 26 can rotate relative to the connecting plate 24.

[0033] Rotational connection between the shaft and the connecting plate: The connecting plate has a shaft hole, the shaft is inserted into the shaft hole, and the shaft and the shaft hole form a clearance fit connection, allowing the shaft to rotate relative to the shaft hole.

[0034] like Figure 16 As shown, the door panel 303 of the machine door 3 is provided with a rice dispensing port 3031 and a viewing window mounting port 3032. The viewing window mounting port 3032 is used to install the machine body viewing window 5. The rice dispensing port 3031 can easily receive the rice unloaded from the rice receiving bin 12 in a bag.

[0035] like Figure 2 As shown, a rice storage window 61 is installed on the side of the rice storage bin 6 near the main body window 5. The rice storage window 61 can be viewed through the main body window 5 and can display the amount of rice stored in the rice storage bin 6.

[0036] It should be noted that the T-type lock 8 is a commonly used locking device. It can be used simply by conventionally installing the T-type lock 8 on the machine door 3 and the machine body 1. When the machine door 3 is closed to the front of the machine body 1, the machine door 3 and the machine body 1 are locked together by the T-type lock 8. To open the machine door 3, the T-type lock 8 is unlocked, thus releasing the fixed connection between the machine door and the machine body, allowing the machine door 3 to be opened.

[0037] To facilitate airflow within the unit, at least two exhaust fan mounting ports are provided on the rear panel. For example, two exhaust fan mounting ports are located at the top and two at the bottom of the rear panel, with an exhaust fan 39 installed at each port. In use, the exhaust fan at the bottom of the rear panel draws outside air into the unit, while the exhaust fan at the top of the rear panel draws air out of the unit, creating airflow within the unit and facilitating heat dissipation.

[0038] To facilitate the collection of rice bran extracted by the rice milling blower, such as Figure 1 , 3As shown in Figure 5, the machine body 1 is equipped with a rice bran chamber 15, and the bran outlet 131 of the rice milling blower 13 extends into the rice bran chamber 15. The bran outlet 131 is connected to a bran collection bag, which is used to collect the bran powder discharged from the bran outlet. The bran collection bag can be an anti-static bran collection bag with an air permeability of <50L / m²·s.

[0039] To close the rice bran chamber, a door 14 is added. One end of the door 14 is rotatably connected to the rice bran chamber 15, and the other end is connected to the side of the rice bran chamber 15 via a drawer lock 21.

[0040] It should be noted that the drawer lock is a commonly used locking device. It can be used by simply installing the drawer lock on the side of the storage door or rice bran compartment.

[0041] like Figure 4 As shown, in order to facilitate the installation of the rice milling drive motor 49, a first support plate 50 is installed inside the machine body 1. The first support plate 50 is used to support the installation of the rice milling drive motor 49.

[0042] like Figure 2 , 4 As shown in Figure 19, the machine body 1 is also provided with a support frame 32, which is installed on the first support plate 50 and is used to support and install the rice milling blower 13 and the rice huller 30.

[0043] like Figure 1 As shown, the intelligent control panel 7 can be installed on the machine door 3. The intelligent control panel 7 can be used to send instructions to the main control board. The main control board controls the operation of the screw conveyor 28, rice huller 30, rice milling exhaust fan 13, outlet pressure regulating mechanism 31, rice unloading mechanism 16, and rice milling drive motor 49 according to the received instructions.

[0044] The first weighing device 23 and the second weighing sensor 47 transmit the weight data they have monitored to the main control board 63. The main control board 63 analyzes and processes the received weight data and then transmits it to the intelligent control screen. The intelligent control screen can display the data information corresponding to a single weighing device and the data information of the sum of the weights of the two weighing devices.

[0045] like Figure 2 , 8 As shown, a second support plate 61 is installed inside the machine body 1. The second support plate 61 is used to support the installation of the rice receiving compartment 12. That is, two second weighing sensors 47 are symmetrically installed on the rice receiving compartment 12, and each second weighing sensor 47 is mounted on the bent support plate 61 through a bracket 48.

[0046] like Figure 7 As shown, the bending support plate 61 is vertically installed inside the machine body 1, with its top bent at 90° to form a horizontal support surface, which is used to support the mounting bracket 48.

[0047] To protect the second weighing sensor 47, a protective plate 11 is added, such as... Figure 1 , 2 As shown in Figures 3, 5, and 6, one end of the protective plate 11 is located above the second weighing sensor and extends along the structural shape of the second weighing sensor 47 to cover the second weighing sensor, while the other end is bent downward and extended to connect with the second support plate 61.

[0048] Understandably, the protective plate 11 is spaced apart from the second weighing sensor 47. The protective plate does not affect the weight monitoring of the rice bin by the second weighing sensor.

[0049] like Figure 6 , 9 As shown, the bottom of the rice receiving bin 12 is provided with a rice discharge port 121, and a rice discharge cylinder 122 extends downward from the rice discharge port 121. Rice in the rice receiving bin is discharged into the rice discharge cylinder 122 through the rice discharge port 121, and the rice discharge cylinder 122 discharges the rice downward.

[0050] like Figure 1 , 4 As shown, an advertising board 4 is installed near the top of the machine door 3. The advertising board can be used to display advertising information.

[0051] To cover the grain storage silo, a top cover 2 and a first support frame 56 are added. The first support frame 56 is installed on the top of the machine body 1, and it fits snugly around the grain storage silo 6. One end of the top cover 2 is connected to the first support frame 56 via at least two hinges 52. The top cover is fastened to the top of the machine body, thus covering the grain storage silo. like Figure 15 As shown, one end of the top cover 2 is provided with a limiting port 201 and a handle mounting port 202, and the corresponding limiting port on the top cover of the machine door 3 is provided with a limiting rod 22 (e.g., Figure 2 As shown, when the machine door 3 is closed to the machine body, the limit rod 22 is inserted into the limit port 201, and the limit rod 22 can limit the top cover 2. The handle mounting port 202 is used to install the handle, and the handle is embedded in the handle mounting port 202.

[0052] Understandably, when the limit rod 22 is inserted into the limit port 201, the limit rod can lock the top cover, preventing it from being opened. When the machine door is opened, the limit rod moves with the machine door and disengages from the limit port, thus releasing the lock on the top cover, allowing it to be opened.

[0053] like Figure 5 , 6As shown in Figure 14, to filter the rice entering the storage bin, a screen 51, a second telescopic drive 54, a support base 53, a push block 55, and a second support frame 59 are added. The support frame 59 is installed along the bottom edge of the screen 51 and is positioned on the top surface of the storage bin 6. The second telescopic drive 54 has a second piston 541 and is mounted on the support base 53, which is mounted on the machine body 1. One end of the push block 55 is connected to the screen 51, and the other end is connected to the second piston 541.

[0054] When rice is added to the grain storage silo, the second telescopic drive 54 is activated. The second telescopic drive 54 drives the second piston 541 to reciprocate telescopically. The second piston 541... It should be noted that after the grain storage bin, rice receiving bin, and their respective connected components are all installed, the first weighing sensor 232 and the second weighing sensor 47 should be adjusted. When the grain storage bin and rice receiving bin are in an unloaded state, the corresponding measurement values ​​of the first weighing sensor 232 and the second weighing sensor 47 should be adjusted to zero. During use, the weight data obtained by the first weighing sensor 232 reflects the weight of the paddy rice in the grain storage bin, and the weight data obtained by the second weighing sensor 47 reflects the weight of the rice in the rice receiving bin.

[0055] The data obtained from the first weighing sensor 232 and the second weighing sensor 47 are analyzed and processed by the main control board and transmitted to the intelligent control screen in real time. The intelligent control screen can be set with touch buttons for different weights of rice, such as 1 jin, 2 jin, 3 jin, 4 jin, or 5 jin. Of course, the desired weight of rice can also be set on the intelligent control screen as needed. The intelligent control screen can be set to voice wake-up, for example, the voice can be set to "Hi, Xiaoxian Rice". The intelligent control screen can also receive voice commands, such as "I want 1 jin of rice" or "I want 2 jin of rice", etc. Subsequently, the intelligent control screen controls the screw conveyor 28, the rice huller 30, the rice milling exhaust fan 13, the outlet pressure regulating mechanism 31, and the rice unloading mechanism.

[0056] Understandably, the smart control screen can be set with a start touch button and a stop touch button. The start touch button is used to control the rice milling operation of this invention. The stop touch button is used to control the invention to stop operating.

[0057] In some embodiments of this disclosure, at least four wheels 20 are installed at the bottom of the machine body to facilitate movement. The at least four wheels 20 facilitate support for movement. For example, when four wheels 20 are installed, one wheel 20 is installed at each of the four bottom corners of the machine body 1. The wheels can be swivel wheels with brake pads.

[0058] In some embodiments, this disclosure facilitates the acceptance of rice grains discharged from the rice receiving bin 12 by adding a bag supply mechanism 19. For example... Figure 1 , 2 As shown in Figures 4 and 6, the bag supply mechanism 19 is installed below the rice unloading cylinder 122 of the rice receiving compartment 12. A bag for holding rice is pre-placed on the bag supply mechanism. When filling with rice, the bag is pulled along the bag supply mechanism to below the rice unloading port 121, and the bag opening is opened to facilitate receiving the rice unloaded from the rice unloading cylinder.

[0059] like Figure 1 , 2 As shown in Figures 4 and 6, one structure of the bag feeding mechanism 19 includes two bag guide rods 191, a bag opening plate 194, and two bag blocking rods 193. The two bag guide rods 191 are arranged parallel and spaced apart; the bag opening plate 194 is positioned at one end between the two bag guide rods 191. The two bag blocking rods 193 are arranged parallel and spaced apart, and positioned at one end between the two bag guide rods 191. The bag opening plate 194 and the bag blocking rods 193 are elastically bendable.

[0060] like Figure 19 , 20 As shown, the bag 60 has hanging holes 602 on both sides near the top, and a handle 601 is provided between the two hanging holes 602. The bag 60 is suspended from two parallel bag guide rods 191 through the hanging holes, and there is an adhesive point between adjacent bags. Therefore, when one bag is pulled, the other bag that is attached to it is also pulled.

[0061] Initially, all bags are located behind the bag opening plate 194 (which is possible). Figure 20 (For visual reference) When using the bag, insert your finger into the handle 601 and hook the bag outwards. The bag will indent downwards when it touches the bag opening plate. Continue moving the bag, and the bag opening plate will insert into the bag. The bag opening plate will block one side of the bag. The side of the bag hooked by your finger will be pulled until it touches the two bag-blocking rods 193, at which point the bag will be open, and you can unload rice into the bag. After filling the bag with rice, insert your hand into the handle 601 again and grab one side of the bag and pull it outwards. The other side of the bag that is in contact with the bag opening plate will push the bag opening plate, causing it to bend and indent downwards. As you move, the bag opening plate will insert into the adjacent bag, blocking one side of the adjacent bag from moving, while the other side of the adjacent bag will be pulled outwards by the bag filled with rice, thus opening the mouth of the adjacent bag. When the side of an adjacent bag moves and touches the two bag-blocking bars 193, the bag containing rice separates from the adjacent bag from the adhesive point due to the blocking effect of the bag opening plate, so that the bottom of the rice receiving compartment still has a bag in an open state.

[0062] Understandably, the adhesive force between adjacent bags is less than the force exerted by the bag spreader to prevent the bags from moving.

[0063] The bag opening plate 194 and the bag blocking rod 193 can be made of food-grade silicone. For example, the bag opening plate 194 is a food-grade silicone sheet. The bag blocking rod 193 is a food-grade, square-shaped silicone rod. The thickness of the silicone sheet and silicone rod can be 2-5mm. Thicknesses of 2mm, 3mm, 4mm, or 5mm can be selected as needed.

[0064] like Figure 1-5 As shown, the space below the bag supply mechanism 19 is configured as a bagging chamber 44 with a bagging space 441, and a bag retrieval opening is provided on one side of the bagging space 441. The bag retrieval opening is for retrieving bags and bagged rice from the bagging space 441.

[0065] like Figure 1 As shown, to facilitate the detection of whether there are still bags on the bag supply mechanism, a photoelectric sensor 62 is added and installed on the rear side of the bag filling space 441. The photoelectric sensor 62 can be located below the bag opening plate 194. The photoelectric sensor 62 monitors the bags in the bag filling space in real time and transmits the monitoring data to the main control board 63 in real time. The data received by the main control board 63 is analyzed and processed and displayed on the intelligent control screen. A display unit can be set on the intelligent control screen to show whether there are bags in the bag filling space 441. For example, if there are bags, the display unit displays green. When no bags are detected, the display unit displays red and flashes, so that the operator can replenish bags in the bag filling space 441 in a timely manner.

[0066] like Figure 2 , 7 As shown, in order to close the bag-taking opening and make the bag-filling space a closed space, a bag-filling chamber door mechanism 33 is added. The bag-filling chamber door mechanism 33 is installed on the machine body 1 and can move to close the bag-taking opening.

[0067] The bagging chamber door mechanism 33 includes a corner plate 58, a guide rod 37, a bagging chamber door 34, a contact piece 35, a bagging chamber door drive mechanism 33, a first photoelectric sensor 36, and a second photoelectric sensor 38. The guide rod 37 is arranged parallel to the corner plate 58. One end of the bagging chamber door 34 is slidably connected to the corner plate 58, and the other end is slidably connected to the guide rod 37. The bagging chamber door drive mechanism 33 is mounted on the corner plate 58 and is drively connected to the bagging chamber door 34. The contact piece 35 is mounted on the bagging chamber door 34. The first photoelectric sensor 36 and the second photoelectric sensor 38 are spaced apart along the length of the guide rod 37.

[0068] like Figure 7As shown, the corner plate 58 can be a right-angle plate structure. During installation, one side of the corner plate 58 is vertically installed on the bending support plate 61, and the other side extends beyond the bending support plate 61, so that the corner plate 58 can be fitted onto the top of the bagging chamber door 34, and can also guide the sliding of the bagging chamber door 34.

[0069] like Figure 2 , 6 As shown in Figure 7, an installation structure for the guide rod 37, the first photoelectric sensor 36, and the second photoelectric sensor 38 is given: a transverse rod 301 is provided on the front end face of the body 1, the guide rod 37 is installed on the top surface of the transverse rod 301, and the first photoelectric sensor 36 and the second photoelectric sensor 38 are installed at intervals on the side of the transverse rod 301.

[0070] Both the first photoelectric sensor 36 and the second photoelectric sensor 38 are electrically connected to the main control board 63. The distance between the first photoelectric sensor 36 and the second photoelectric sensor 38 can be equal to or slightly greater than the width of the bagging chamber door. When the contact piece 35 moves from the first photoelectric sensor 36 to the second photoelectric sensor 38, the bagging chamber door completely disengages from the bag-retrieving opening.

[0071] The operating mode of the first photoelectric sensor 36 and the second photoelectric sensor 38 is as follows: When the contact piece 35 is placed on the first photoelectric sensor 36, the first photoelectric sensor 36 is triggered and transmits data information to the main control board 63. The main control board 63 then controls the bagging chamber door drive mechanism 33 to temporarily stop operating, and the bagging chamber door 34 stops moving. When the contact piece 35 moves to the second photoelectric sensor 38, the second photoelectric sensor 38 is triggered and transmits data information to the main control board 63. The main control board 63 then controls the bagging chamber door drive mechanism to pause operating.

[0072] It should be noted that in the initial state, the bagging chamber door 34 is closed to the bag taking opening of the bagging space 441, and at this time, the contact piece 35 is placed on the first photoelectric sensor 36.

[0073] like Figure 7 As shown, a guide groove is provided along the length of the guide rod 37. At least two rollers 57 are provided at the bottom of the bagging chamber door 34, and these rollers 57 are positioned within the guide groove. The bagging chamber door 34 can move along the guide groove by means of these rollers. It is understood that the guide groove can restrict the rollers and prevent them from detaching from the guide rod during rolling.

[0074] In order to allow viewing of the bagging space through the bagging chamber door 34, a bag door viewing window 341 is provided on the bagging chamber door 34. It can be understood that when the bagging chamber door 34 is closed to the bag taking opening, the bag door viewing window 341, the rice taking opening 3031, and the rice taking window 181 are aligned, and the situation inside the bagging space 441 can be viewed through the rice taking window 181, the rice taking opening 3031, and the bag door viewing window 341.

[0075] It should be noted that the intelligent control screen is equipped with an open touch button and an close touch button for the bagging chamber door drive mechanism 33. For example, when the open touch button is touched, the intelligent control screen 7 immediately sends a control to the main control board 63 to operate the bagging chamber door drive mechanism 33. The bagging chamber door drive mechanism 33 drives the bagging chamber door 34 to move. The bagging chamber door 34 moves the contact piece 35 to the second photoelectric sensor 38. The second photoelectric sensor 38 sends data information to the main control board. When the main control board receives the data information, it controls the bagging chamber door drive mechanism 33 to stop working, and the bagging chamber door 34 disengages from the bag-removing opening, which is now open. When a hand touches the off touch button, the smart control screen sends off data information to the main control board. Upon receiving this off data information, the main control board controls the bagging chamber door drive mechanism 33 to operate, driving the bagging chamber door 34 to move. The bagging chamber door 34 causes the contact piece 35 to move in the opposite direction to the first photoelectric sensor 36. The first photoelectric sensor 36 sends data information to the main control board 63. Upon receiving this data information, the main control board controls the bagging chamber door drive mechanism 33 to pause operation, and the bagging chamber door 34 closes the bag-retrieving opening, leaving the bag-retrieving opening closed. It is understandable that voice commands can be sent to the smart control screen, for example, issuing a voice command to "open the bag-retrieving opening." Upon receiving this voice command, the smart control screen sends corresponding voice command data information to the main control board. After receiving this voice command data information, the main control board controls the bagging chamber door drive mechanism 33 to perform the same action as "open the touch button." When the voice command "Close the bag opening" is issued, the intelligent control screen receives the voice command and sends the corresponding voice command data information to the main control board. After receiving the voice command data information, the main control board controls the bagging chamber door drive mechanism 33 to perform the same operation as "Close the touch button".

[0076] like Figure 7 As shown, a structure of a bagging chamber door drive mechanism is presented. The bagging chamber door drive mechanism includes a first telescopic drive member 331, a connecting rod 333, a third nut 332, and a push block 334. The first telescopic drive member 331 is provided with a piston. The connecting rod 333 passes through the piston and connects to the push block 334. The connecting rods located on both sides of the piston are provided with third nuts 333. When the third nuts 333 on both sides are tightened, the third nuts are tightly attached to the piston, and the connecting rod 333 is fixedly connected to the first piston.

[0077] One possible structure for the first telescopic drive component is an electric push rod.

[0078] The first telescopic drive component is working: When the bagging chamber door is extended, the piston driven by the first telescopic drive component 331 extends. The piston pushes the connecting rod 333, which in turn moves the push block 334. The push block 334 pulls the bagging chamber door 34 away from the bagging space 441 towards the bag-taking opening. When it moves to the point where the contact piece 35 triggers the second photoelectric sensor 38, the second photoelectric sensor 38 sends a data signal to the main control board 63. Upon receiving this data signal, the main control board 63 can control the first telescopic drive component 331 to stop working. At this time, the bag-taking opening is open. The bag-taking opening, the rice-taking opening 3031, and the rice-taking window 181 are connected. Customers who want to mill rice can insert their hands through the rice-taking window 181, the rice-taking opening 3031, and the bag-taking opening into the bagging space 441 to take out the bag containing rice.

[0079] When the bagging chamber door is closed upon reset, the piston driven by the first telescopic drive component 331 retracts. The piston pushes the connecting rod 333, which in turn moves the push block 334. The push block 334 pulls the bagging chamber door 34 towards the bag-retrieving opening. When it reaches the contact plate 35, it triggers the first photoelectric sensor 36, which then sends data to the main control board 63. Upon receiving this data, the main control board 63 can control the first telescopic drive component 331 to stop operating. The bagging chamber door 34 then closes at the bag-retrieving opening and rice-retrieving opening 3031, thus preventing entry into the bagging space 441.

[0080] like Figure 3 , 7 As shown, a sealing strip 46 is provided on the side of the bagging chamber door 34 near the rice dispensing opening 3031. The sealing strip is distributed on the bagging chamber door 34 according to the shape of the rice dispensing opening 3031. When the bagging chamber door 34 is closed to the bag dispensing opening and the rice dispensing opening 3031, the sealing strip adheres to the edge of the rice dispensing opening, which can realize the airtight connection between the bagging chamber door 34 and the rice dispensing opening 3031.

[0081] In some embodiments of this disclosure, one structure of the rice unloading mechanism is provided. For example... Figure 8 , 21 As shown, the unloading mechanism 16 includes a base 165, a servo motor 1610, a star wheel 166, a fulcrum rod, a swing rod 1611, a plug 161, and a spring 1614. The servo motor 1610 is mounted on the base 165 and has an output shaft. The star wheel 166 is connected to the output shaft. The fulcrum rod is spaced apart from the servo motor 1610. The swing rod 1611 is hinged to the fulcrum rod, and one end of the swing rod 1611 is connected to the star wheel 166 via a chain 167. The plug 161 is connected to the other end of the swing rod 1611 via a pull rod 162. One end of the spring 1614 is connected to the swing rod 1611, and the other end is connected to the fulcrum rod.

[0082] One structure of the plug 161 includes a conical end and a hemisphere, with the conical end at the top of the hemisphere. In use, the hemisphere seals the rice discharge port 121, preventing rice from leaking out. During the plug's upward movement, the conical end prevents rice from remaining on the plug. Furthermore, the conical end reduces the resistance of the rice in the receiving compartment to the plug as it moves upward.

[0083] Understandably, the diameter of the hemisphere is slightly larger than the diameter of the unloading port's cross-section. This allows the hemisphere to effectively seal the unloading port.

[0084] The servo motor 1610 can be set to rotate at a set angle. When the servo motor 1610 drives the star wheel 166 to rotate to the set angle, it will rotate in the opposite direction to reset. When the star wheel 166 rotates, it drives the chain 167 to move. The chain 167 pulls the swing rod 1611 downward. One end of the swing rod pulled by the chain 167 swings downward, while the other end of the swing rod connected to the plug 161 swings upward. At the same time, it drives the plug 161 to move upward and undergo elastic deformation with the tension spring 1614. The plug 161 disengages from the rice discharge port 121, and the rice in the rice bin 12 falls into the rice discharge cylinder 122 through the rice discharge port 121. The rice discharge cylinder 122 discharges the rice downward and unloads it into the bag below that has been opened.

[0085] When the star wheel 166 rotates in reverse to reset, one end of the swing rod connected to the plug 161 swings downward, and the spring 1614 assists in pulling the swing rod downward, so that the plug re-seals the unloading port of the rice receiving bin 12.

[0086] It should be noted that the spring maintains its elasticity to pull the swing rod, which keeps the chain taut. This facilitates the movement of the chain by the star wheel and prevents the iron rings that make up the chain from being misaligned.

[0087] Understandably, the servo's rotation angle can be preset on the intelligent control screen, and the angle data set on the intelligent control screen is transmitted to the main control board for storage. During operation, the servo's rotation angle can be input through the intelligent control screen, which then transmits the input angle data to the main control board. The main control board can control the servo to drive the star wheel to rotate according to the input rotation angle.

[0088] like Figure 8 As shown, one mounting method for the servo motor is as follows: one end of the base plate 168 is mounted on the base 165, and the other end has a mounting port. The servo motor has a protrusion at one end near the star wheel, and the other end is inserted into the mounting port. The protrusion and the base plate 168 are connected by a first bolt 169.

[0089] A connection structure between the pull rod 162 and the swing rod 1611: the swing rod 1611 is provided with a hook hole, the pull rod 162 is provided with a hook 163, and the pull rod 162 is hooked to the hook hole through the hook 163 to realize the connection between the pull rod and the swing rod.

[0090] like Figure 8 As shown, one structure of the fulcrum rod includes a top rod 164, two support rods 1613, and a second bolt 1612. The top rod 164 is installed on the inner side of the rice receiving compartment. The top of the top rod has two first grooves (not shown in the figure), and one end of each support rod 1613 has a second groove (not shown in the figure). Each first groove engages with one support rod 1613; that is, the second groove on the support rod 1613 engages with the first groove on the corresponding top rod. The two support rods clamp a swing rod 1611, and the two support rods 1613 and the swing rod 1611 are connected by the second bolt 1612. The swing rod 1611 can swing relative to the support rods 1613 with the aid of the second bolt 1612.

[0091] Understandably, when the support rod and the top rod are engaged through the first groove and the second groove, the inner side of the first groove is in contact with the support rod, and the inner side of the second groove is in contact with the top rod, thus achieving the engagement connection between the support rod and the top rod. In addition, with the pulling action of the spring 1614, when the swing rod 1611 swings, the support rod and the top rod remain engaged.

[0092] like Figure 3 As shown, a cover 45 is installed on the top of the rice receiving compartment 12. The cover 45 covers the top surface of the rice receiving compartment and can provide some coverage.

[0093] like Figure 10 As shown, to avoid affecting the installation of the fulcrum rod, the spring, and the swinging rod, the bin cover 45 is provided with a rice inlet 451, a support rod groove 452, a spring groove 453, and a traction rod swinging groove 454. The rice inlet 451 is used to receive rice discharged from the rice discharge port 1003 on the outlet guide chute 10, and the rice falls into the rice receiving bin through the rice inlet. The support rod groove 452 is used for the support rod to pass through the bin cover. The spring groove 453 is used for the spring 1614 to pass through the bin cover 45 and to provide space for the spring to swing. The traction rod swinging groove 454 is used to provide swinging space for the traction rod 162 to swing.

[0094] In some embodiments of this disclosure, one structure of the outlet pressure regulating mechanism is provided. For example... Figure 12As shown, the outlet pressure regulating mechanism 31 includes a second groove 3110, a first groove 318, a lead screw motor 317, a slider 315, a second spring 316, an infrared sensor 311, a swing plate 3116, and a pressure plate 3112. The bottom surface of the second groove 3110 has a pressure plate hole 3111; the first groove 318 is installed at one end of the second groove 3110 and has a sliding groove 3181 at its bottom; the lead screw motor 317 has a lead screw 319; the slider 315 is fitted onto the lead screw 319 and threadedly connected to it, and has a limiting rod 3151 inserted into the sliding groove 3181; the second spring 316 is fitted onto the lead screw 319; the infrared sensor 311 is perpendicular to the lead screw 319 and installed in the first groove 318. The swing plate 3116 is rotatably mounted on the second groove 3110, and one end of the swing plate 3116 is connected to the second spring 316. The pressure plate 3112 is placed in the pressure plate hole 3111 and is connected to the swing plate 3116 through a push-pull mechanism.

[0095] like Figure 12 As shown, one structure of the push-pull component includes a sleeve 3113, a capped screw 3114, and a first nut 3115. The sleeve 3113 is fitted onto the capped screw 3114, and the capped screw 3114 passes through the sleeve and is threadedly connected to the first nut 3115.

[0096] In use, the uncapped end of the capped screw 3114 passes through the second through hole 31162 of the pressure plate 3112, sleeve 3113, and swing plate 3116, and is threadedly connected to the first nut 3115. When the first nut 3115 is tightened, the capped screw 3114 and the first nut 3115 clamp and fix the pressure plate 3112, sleeve 3113, and swing plate 3116 together. The sleeve 3113, placed between the pressure plate and the swing plate, not only limits the gap between the pressure plate and the swing plate, but also reinforces the pressure plate.

[0097] like Figure 11 , 12 As shown, one installation method for the infrared sensor 311 is as follows: The working end of the infrared sensor 311 is sequentially connected to a first nut 312, a mounting groove 3182, a washer 313, and a second nut 314. The first nut 312 and the second nut 314 are threadedly connected to the infrared sensor 311. The second nut 314 can serve as a limiting nut. When the second nut 314 is helically moved to the desired position, the first nut 312 is then tightened. When the first nut 312 is tightened, it and the second nut 314 clamp and fix the washer to the side of the first groove, thereby mounting the infrared sensor 311 onto the first groove 3182 via the first nut 312 and the second nut 314. The infrared sensor 311 is electrically connected to the main control board 63.

[0098] One structure of the pressure plate 3112 can be a circular plate, with the periphery of the circular plate folded to form a hollow frustum structure.

[0099] One method of rotating installation of the swing plate: the swing plate 3116 is inserted into the second groove 3110, one end of the support shaft 3117 passes through the second groove 3110, the swing plate 3116 is threadedly connected to the third nut 3118, and the other end is provided with an anti-detachment plate.

[0100] In order for the swing plate to swing relative to the second groove with the help of the support shaft, first tighten the third nut 3118, and then turn it in the opposite direction two or three turns to release the third nut from the lock, so that the swing plate 3116 can swing with the help of the support shaft.

[0101] like Figure 12 As shown, one end of the outlet guide trough 10 with a rice receiving port 1002 is placed at the bottom of the second tank 3110. The rice receiving port 1002 is used to receive the rice discharged from the second tank 3110.

[0102] like Figure 12 As shown, an observation window 1001 is provided on the top of the outlet guide chute 10 along its length, which allows for easy observation of the rice flow. A discharge port 1003 is provided at the other end of the outlet guide chute 10.

[0103] The infrared sensor 311 is used for initial positioning. That is, when the slider 315 corresponds to the infrared sensor 311, the second spring 316 has no pushing force on the swing plate 3116.

[0104] It should be noted that the intelligent control screen is equipped with start, stop, forward, and reverse touch buttons for the outlet pressure adjustment mechanism. It also features a display unit for the number of rotations of the lead screw motor. The minimum and maximum rotation numbers of the lead screw motor can be set via the intelligent control screen. At the minimum rotation number, the slider aligns with the infrared sensor, resulting in the smallest distance between the slider and the lead screw motor. At the maximum rotation number, the slider moves to its maximum stroke, maximizing the distance between the slider and the lead screw motor. The force exerted by the second spring on the swing plate is also at its maximum, and the pressure plate 3112 exerts maximum resistance on the rice grains at the rice outlet 3002. In essence, the rotation number input on the intelligent control screen, falling between the minimum and maximum rotation numbers, allows adjustment of the resistance exerted by the pressure plate 3112 on the rice grains at the rice outlet 3002, thus achieving different degrees of rice whitening.

[0105] How the export pressure regulating mechanism works: The intelligent control panel sends data commands to the main control board to control the outlet pressure regulating mechanism.

[0106] The operator inputs the number of revolutions of the lead screw motor through the intelligent control screen 7, and then sends a data command to the main control board 63 to start the lead screw motor 317. Upon receiving this data command, the main control board starts the lead screw motor 317, which drives the lead screw 319 to rotate. The slider 315 is threadedly connected to the lead screw 319, and the slider 315 has a limiting rod 3151 that inserts into the slide groove 3181, thus limiting the rotation of the slider 315. Therefore, the lead screw 319... 9. While pushing the slider 315 toward the swing plate 3116, it squeezes the second spring 316. The second spring 316 then pushes the swing plate 3116. One end of the swing plate 3116, which is connected to the spring, swings forward, and the other end swings toward the rice outlet 3002 of the rice huller 30. The pressure plate 3112 is installed on the swing plate 3116 through a push-pull component. The swing plate 3116 drives the pressure plate 3112 to move toward the rice outlet 3002, reducing the distance between the pressure plate 3112 and the rice outlet 3002, thereby increasing the rice outlet pressure.

[0107] When the number of revolutions of the lead screw motor reaches the input value, the main control board 63 controls the lead screw motor to stop working. The slider and the lead screw threaded connection have a self-locking function. The slider maintains its current state and compresses the second spring. The second spring maintains the time elastic deformation force on the swing plate, so that the pressure plate maintains the blocking effect on the rice outlet.

[0108] To facilitate the separation of the internal parts of the machine body 1, a baffle 9 is added. For example... Figure 1-3 As shown in Figures 1 and 13, the body 1 is provided with two parallel bending brackets 27 spaced apart, and baffles 9 are installed on the two bending brackets 27.

[0109] like Figure 13 As shown, the bending bracket 27 includes a first vertical bracket, a horizontal bar, and a second vertical bracket. The first vertical bracket is installed vertically, with its top connected to one end of the horizontal bar, and the other end of the horizontal bar connected to the second vertical bracket. The horizontal bar is vertically connected to both the first and second vertical brackets.

[0110] The baffle 9 includes a first vertical plate 99, a first flat plate 94, a second vertical plate 95, and a second flat plate 96. The first vertical plate 99 is installed between the two first vertical supports, the first flat plate 94 is installed between the two crossbars, and the second vertical plate 95 is installed between the two second vertical supports. A V-shaped opening 97 is provided in the middle of the second vertical plate 95. The second flat plate 96 is perpendicularly connected to the second vertical plate 95. The two sides of the first flat plate 94 are perpendicularly connected to the first vertical plate 99 and the second vertical plate 95, respectively.

[0111] The V-shaped opening 97 on the second vertical plate 95 corresponds to the rice storage window 61 on the grain storage bin 6, which can prevent the second vertical plate from blocking the rice storage window 61.

[0112] The second flat plate 96 is provided with a second recess 98, and the second flat plate 96 is fitted onto the grain storage bin 6 through the second recess 98.

[0113] The first vertical plate 99 is provided with a swing groove 91, a discharge groove 92 and a first recess 93. The swing groove 91 allows the swing rod 1611 to swing up and down. The discharge groove 92 allows the outlet guide groove 10 to pass through the first vertical plate 99. The first recess 93 allows the first vertical plate 99 to be fitted onto the rice receiving bin 12.

[0114] The working principle of this utility model is as follows: Send the voice command "Hi, Xiaomi" to the smart control screen 7, and the smart control screen will be woken up and put into standby mode.

[0115] Then, a voice command, "I want 2 jin of rice," is sent to the intelligent control screen 7. The intelligent control screen 7 sends data information to the main control board 63. The main control board controls the screw conveyor 28 and the rice milling drive motor 49 to start according to the corresponding data information. The rice milling drive motor 49 simultaneously drives the rice huller 30 and the rice milling exhaust fan 13. The screw conveyor 28 transports the paddy in the storage bin 6 to the guide hopper 29, which then guides the paddy into the rice huller 30. The rice huller 30 dehulls the paddy into rice. The bran powder produced in the rice huller 30 is extracted by the rice milling exhaust fan 13. The rice huller 30 then transfers the rice from the rice milling exhaust fan 13 to the rice milling exhaust fan 13. The rice outlet 3002 extends outward, and at the rice outlet 3002 is a pressure plate 3112 in the outlet pressure regulating mechanism 31. Rice falls from the gap between the rice outlet 3002 and the pressure plate 3112 into the outlet guide chute 10. The outlet guide chute 10 guides the rice into the receiving bin 12. The second weighing sensors 47 on both sides of the receiving bin 12 monitor the weight of the rice in the receiving bin in real time and transmit the data information to the main control board 63 in real time. When the weight of the rice in the receiving bin 12 reaches the required 2 jin of rice, the main control board 63 controls the screw conveyor 28, the rice huller 30, and the rice milling exhaust fan 13 to stop working. Meanwhile, the bags in the bagging chamber 44 are already open and located below the unloading cylinder 122 on the receiving bin 12. The main control board 63 simultaneously controls the rice unloading mechanism 16 to work. The swing rod 1611 drives the plug 161 to move upward through the pull rod 162. The plug 161 disengages from the unloading port 121 at the bottom of the rice receiving bin 12. The rice in the rice receiving bin 12 falls into the unloading cylinder 122 through the unloading port 121. The unloading cylinder 122 then collects and unloads the rice into a bag.

[0116] The main control board 63 also controls the operation of the bagging chamber door drive mechanism 33. After the bagging chamber door drive mechanism 33 moves the bagging chamber door 34 and disengages from the bag-removing opening, the operation is temporarily suspended. Then, the bags containing rice in the bagging space 441 can be removed through the rice-removing window 181, the rice-removing opening 3031, and the bag-removing opening of the bagging chamber 44. When the bag containing rice is removed, the adjacent bag is pulled below the rice unloading cylinder 122 and is in the open state.

[0117] After the bag containing rice is removed, data information can be sent from the intelligent control screen 7 to the main control board 63 to control the bagging chamber door drive mechanism 33 to reset and close the bagging chamber door 34 at the bag taking opening. In this way, the bagging chamber door separates the bag taking opening from the rice taking opening 3031, and the bagging chamber door also blocks the rice taking opening 3031.

[0118] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
