[0045] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0046] In order to achieve the above objectives,

[0047] Reference Figures 1-5 This application provides a solar-powered rice milling machine, which is a rectangular shell 1. Inside the shell 1 are a motor 2 and a rice milling mechanism 3. The motor 2 is connected to the rice milling mechanism 3 via a transmission connection. The motor 2 drives the rice milling mechanism 3 to remove the husks and whiten the paddy rice entering the rice milling mechanism 3, obtaining edible germ rice. The top of the shell 1 has a feed inlet 11, and the bottom of the shell 1 has a discharge outlet 12 and a waste outlet 13. The feed inlet 11 is connected to the rice feeding structure of the rice milling mechanism 3, the discharge outlet 12 is connected to the rice discharge structure of the rice milling mechanism 3, and the waste outlet 13 is located below the rice milling mechanism 3, allowing the separated rice bran to fall off the shell 1.

[0048] When in use, paddy rice or brown rice is put into the rice inlet of the shell 1. The paddy rice enters the rice milling mechanism 3 through the rice inlet. The milling rollers remove the husks and mill the paddy rice to obtain edible germ rice. The germ rice is transported from the rice outlet of the rice milling mechanism 3 to the rice inlet of the rice outlet regulating mechanism. The germ rice is then transported from the rice outlet of the rice outlet regulating mechanism to the rice outlet of the shell 1. The germ rice is then output from the rice outlet for people to cook and use.

[0049] Meanwhile, an adjustment component 6 is movably mounted on the outer side of the housing 1, and a first photovoltaic panel 4 is mounted on the movable end of the adjustment component 6. By driving the photovoltaic panel through the adjustment component 6, the position and tilt angle of the photovoltaic panel can be adjusted.

[0050] Specifically, refer to Figures 5-9 The adjustment component 6 in this embodiment includes a vertical lifting plate 61 and an inclined member 62 disposed on the side of the vertical lifting plate 61 away from the housing 1. One end of the first photovoltaic panel 4 is rotatably connected to the vertical lifting plate 61, and the other end is hinged to the inclined member 62.

[0051] The vertical lifting plate 61 moves back and forth in the vertical direction relative to the shell 1, thereby adjusting the vertical displacement of the first photovoltaic panel 4. The tilting member 62 is set to adjust the tilt angle of the first photovoltaic panel 4, thereby adjusting the angle between the first photovoltaic panel 4 and the direction of sunlight, thus improving the solar energy collection efficiency.

[0052] Therefore, this application has the following advantages over the prior art by adding a photovoltaic panel:

[0053] First, while maintaining portability, solar energy is supplied by photovoltaic panels, reducing the demand for mains electricity.

[0054] Second: By adjusting the tilt angle of the photovoltaic panels, the efficiency of solar energy collection can be further improved.

[0055] Optionally, a storage battery is installed inside the housing 1. The storage battery is electrically connected to the photovoltaic panel and the motor 2 respectively. By installing the storage battery, solar energy can be collected, so that the rice milling machine can be used on cloudy days or at night when the light is poor. On the other hand, it can overcome the defect that the motor 2 cannot operate stably due to inconsistent light intensity when the photovoltaic panel and the motor 2 are directly connected.

[0056] Furthermore, in this embodiment, the battery can be detachably connected to the housing 1 via bolts. Meanwhile, the motor 2 is a DC motor used in conjunction with the battery.

[0057] Optionally, the waste inlet 13 in this embodiment can be detachably installed in the chaff receiving trough by snap-fit.

[0058] As an optional implementation, the vertical lifting plate 61 is provided with a guide block 611 on the side near the housing 1, and the housing 1 is provided with a guide groove 612 that cooperates with the guide block 611, so that the vertical lifting plate 61 moves back and forth relative to the housing 1 in the vertical direction; by embedding the guide block 611 into the limiting groove, the movement direction of the guide block 611 and the vertical lifting plate 61 is limited.

[0059] It also includes a limiting bolt 613, a vertical lifting plate 61 with a mounting hole 614, and a housing 1 with a plurality of first screw holes 615 that mate with the mounting hole 614 at intervals. The plurality of first screw holes 615 are spaced apart along the moving direction of the vertical lifting plate 61. By passing the limiting bolt 613 through the mounting hole 614 and threading it with any of the first screw holes 615, the position of the vertical lifting plate 61 is fixed.

[0060] It should be noted that the method of moving the vertical lifting plate 61 relative to the housing 1 by sliding the limiting block embedded in the limiting groove in this embodiment is only an optional manual driving method. In other embodiments, an electric telescopic rod 621 or bolts can be used to fix the vertical lifting plate 61 to different positions of the housing 1 to achieve vertical adjustment of the vertical lifting plate 61.

[0061] Meanwhile, fixing the position of the vertical lifting plate 61 by using the limiting bolt 613 is only one optional implementation method in this embodiment. In other embodiments, the position of the vertical lifting plate 61 can also be fixed by means of pins or interference fit.

[0062] The tilting member 62 includes a telescopic rod 621 and a slider 622. The vertical lifting plate 61 is provided with a groove 623. The slider 622 is slidably disposed in the groove 623. The two ends of the telescopic rod 621 are rotatably connected to the slider 622 and the first photovoltaic panel 4, respectively.

[0063] By moving the slider 622 back and forth relative to the slide groove 623, one end of the telescopic rod 621 is driven to move back and forth in the vertical direction, so that the other end of the telescopic rod 621 drives the first photovoltaic panel 4 to move upward, rotate or reset, which can increase the range of the tilt angle of the first photovoltaic panel 4.

[0064] Specifically, refer to Figure 9 In this embodiment, the telescopic rod 621 includes an adjusting rod 6211 hinged to the vertical lifting plate 61. A sliding sleeve 6212 is slidably sleeved on the side of the adjusting rod 6211 away from the vertical lifting plate 61. The side of the sliding sleeve 6212 away from the adjusting rod 6211 is hinged to the first photovoltaic panel 4.

[0065] It should be noted that the use of telescopic rod 621 and slider 622 to adjust the tilt angle of the first photovoltaic panel 4 in this embodiment is only one optional implementation method. In other embodiments, electric telescopic rod 621 or servo motor 2 or other structures can be used to adjust the tilt angle of the first photovoltaic panel 4.

[0066] The sliding sleeve 6212 is provided with a second threaded hole and a locking bolt 6213 that mates with the second threaded hole. The locking bolt 6213 passes through the sliding sleeve 6212 and abuts against the adjusting rod 6211. The adjusting rod 6211 is fixed to the sliding sleeve 6212 by the bolt.

[0067] The number of adjustment components 6 and the number of first photovoltaic panels 4 are both two, which are spaced apart on both sides of the housing 1 and are mirror images of each other. Each adjustment component 6 includes two telescopic rods 621 and two sliders 622.

[0068] Optionally, in this embodiment, the top of the housing 1 is provided with an opening 14 and a cover plate 15 for sealing the opening 14. The feed end of the feed inlet 11 is connected to the opening 14. The cover plate 15 is movably disposed on the housing 1. A second photovoltaic panel 5 is provided on the top of the cover plate 15. By providing the cover plate 15 to seal the opening 14, the feed inlet 11 can be protected, and the rice grains can be prevented from escaping from the rice milling mechanism 3. By providing the second photovoltaic panel 5 on the top of the cover plate 15, the solar energy collection efficiency can be improved.

[0069] The opening 14 is provided with a limiting rod 142, and the cover plate 15 is provided with a limiting hole 141. The limiting rod 142 passes through the limiting hole 141, and the extension direction of the limiting rod 142 is parallel to the extension direction of the shell 1.

[0070] Specifically, refer to Figures 7-8 In this embodiment, the top of the housing 1 is provided with a first mounting groove and a second mounting groove spaced apart. The first mounting groove is provided with an elastic element 18 and a first movable element 16, and the second mounting groove is provided with an elastic element 18 and a second movable element 17.

[0071] The cover plate 15 is provided with a through hole 151. When the opening 14 is closed, the first movable member 16 enters the through hole 151. When the opening 14 is open, the second movable member 17 enters the through hole 151.

[0072] When the cover plate 15 closes the opening 14, the cover plate 15 is moved so that the through hole 151 is above the first mounting groove. The first movable member 16 enters the through hole 151 under the action of the elastic member 18. When the cover plate 15 opens the opening 14, the first movable member 16 in the first mounting groove is pressed down, and the cover plate 15 is pushed so that the elastic member 18 exits from the through hole 151. The cover plate 15 is then moved so that the through hole 151 is above the second mounting groove, so that the second movable member 17 in the second mounting groove enters the through hole 151, thereby fixing the cover plate 15.

[0073] Among them, the elastic element 18 can be a spring.

[0074] In practical use, it was found that the rice milling mechanism 3, due to the removal of the cooling fan in existing technologies to reduce the weight and size of the equipment, experienced issues during prolonged use.

[0075] Friction between the rollers and the rice grains can cause heat buildup. With prolonged use, if the heat cannot dissipate quickly enough, the temperature will rise. This can affect rice milling efficiency and even damage machine parts, such as roller deformation or bearing lubrication failure. Furthermore, when the temperature exceeds 60°C, starch molecular chains break down, resulting in less stickiness and a harder texture in the cooked rice.

[0076] Therefore, a temperature sensor 7 is installed inside the rice milling mechanism 3, and a processing module is installed in the housing 1. Both the temperature sensor 7 and the motor 2 are electrically connected to the processing module.

[0077] Optionally, the processing module in this embodiment can use a 51 microcontroller, and the temperature sensor 7 can be a temperature sensor 7 installed on the inner side wall of the housing 1, 5-10 cm away from the side of the rice milling mechanism 3, or a thermocouple (K-type) temperature sensor 7 installed inside the roller bearing seat of the rice milling mechanism 3.

[0078] When the temperature sensor 7 detects that the temperature inside the rice milling mechanism 3 exceeds 60°C, the device is stopped by a preset program in the processing module.

[0079] In the existing technology, the rice milling mechanism 3 sometimes runs idle, which leads to energy waste and equipment wear. The feed inlet 11 is funnel-shaped. A photoresistor 8 and a light source 9 are installed at the bottom of the feed inlet 11. Both the photoresistor 8 and the light source 9 are electrically connected to the processing module, which can detect whether there is rice accumulation in the feed inlet 11 in a timely manner. When the photoresistor 8 detects that there is no rice accumulation in the feed inlet 11, it stops the rice milling mechanism 3 after an interval of 5 seconds, thereby effectively avoiding the rice milling mechanism 3 running idle.

[0080] Optionally, the light source 9 in this embodiment can be an LED light source 9.

[0081] It should be noted that the use of a photoresistor 8 and a power supply to detect the buildup in the feed inlet 11 in this embodiment is only one optional implementation method. In other embodiments, pressure sensors or other methods can also be used for detection.

[0082] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. It is obvious to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and that the present application can be implemented in other specific forms without departing from the spirit or basic characteristics of the present application.
