[0033] The rice metering device is used to deliver rice into the accommodating cavity of the frame 21;

[0034] The pressing device is used to press the rice in the accommodating cavity.

[0035] wherein the frame 21 is provided with a holding cavity for holding rice, and the frame 21 may be in a rectangular, cylindrical or other shape, preferably a regular shape, so as to be compatible with the shape of the lunch box and to facilitate the entry of rice; the feed port on the holding cavity is provided above the frame 21, and the size of the feed port should be as large as possible to facilitate the entry of rice into the holding cavity, and the size of the discharge port should be as large as possible to facilitate the rice to fall out of the frame 21, so as to avoid the blocking effect of the frame 21 structure on the rice, resulting in rice remaining inside the frame 21; preferably, the frame 21 is a cylindrical or square tubular structure with a through top and bottom, so as to ensure that the inner wall of the frame 21 can be in a vertical state during actual installation, so as to ensure that the rice can automatically fall out of the discharge port under the action of gravity; the restraining member is not limited to the strip-shaped restraining member provided in this embodiment, as long as it can fix the frame 21, and the frame 21 and the restraining member should be detachably connected, so that the frame 21 can be removed and cleaned conveniently; the bottom plate 12 is a rectangular The plate body, the bottom plate 12 is placed at the bottom of the frame body 21 and contacts it, and has a sealing effect on the discharge port at the bottom of the frame body 21. When the rice is put into the accommodating cavity, the bottom plate 12 is equivalent to the bottom of the accommodating cavity and supports the rice; when the bottom plate 12 slides, the rice discharge port 121 provided on the bottom plate 12 is communicated with the discharge port on the accommodating cavity, and the rice can enter the rice discharge port 121 from the accommodating cavity; preferably, the projection of the discharge port on the bottom plate 12 can be completely located within the range of the rice discharge port 121; the pressing device can be a connecting rod, and a pressing plate is provided on the connecting rod. After the rice metering device is closed, the pressing device is immediately started to drive the connecting rod to achieve pressing, and is not limited to this pressing method; the constraint structure includes a first supporting device 8 and a second supporting device 16, and is installed on both sides of the frame body 21 to fix the frame body 21. The constraint structure is not limited to this form, as long as it can achieve the fixation of the frame body 21.

[0036] The specific implementation process of this embodiment is as follows:

[0037] Before use, a layer of water can be sprayed on the frame 21 and the bottom plate 12 to reduce the stickiness of the rice; the user puts the lunch box on the lower side of the bottom plate 12, just below the discharge port of the frame 21; the user selects the required amount of rice, and the rice metering device automatically delivers the rice into the accommodating cavity of the frame 21 according to the user's needs. At this time, the bottom plate 12 is in a state of closing the discharge port of the accommodating cavity and plays a role in supporting the rice; after the rice metering device finishes delivering the rice, the pressing device is activated to press the rice to ensure that the rice fits the accommodating cavity, the top layer is flat, and relatively pressed; after pressing, the bottom plate 12 slides During the sliding process, the rice outlet 121 on the bottom plate 12 is connected with the discharge port of the accommodating cavity, and the rice falls into the lunch box from the accommodating cavity; the distance between the lunch box and the bottom plate 12 should be relatively close, and the rice is compacted, so when the rice enters the lunch box, it can be kept as intact as possible, occupying less space in the lunch box, and the rice will not be scattered; the problem of rice overflowing and the need to increase the size of the lunch box accordingly due to the rice being too fluffy is avoided; and the whole process is fully automatic for the equipment to discharge rice, which solves the problems of manual rice beating being easy to fatigue, uneven rice beating and low efficiency, can better meet people's needs, and is flexible.

[0038] Based on the above embodiment, Figure 1 、 2 , also includes a cover plate 20 and a driving assembly; the cover plate 20 is arranged above the frame 21 and can cover the feed port, and a rice inlet 201 is provided on the cover plate 20; the driving assembly can simultaneously drive the cover plate 20 and the bottom plate 12 to move in opposite directions; when the feed port and the rice inlet 201 are connected, the discharge port and the rice outlet 121 are closed.

[0039] Wherein, the cover plate 20 is a rectangular plate with the same size and outer contour as the bottom plate 12, which is convenient for processing and linkage; the cover plate 20 can cover the feed port of the frame 21, and when the cover plate 20 slides, the rice feed port 201 on the cover plate 20 can be aligned with the feed port, and the projection of the rice feed port 201 on the frame 21 should be smaller than or equal to the discharge port, to ensure that the rice can all enter the accommodating cavity when passing through the rice feed port 201; when the feed port is aligned with the rice feed port 201, the rice metering device starts to operate, and a sensor can be set at the feed port or the rice feed port 201; or a switch can be set, and when the switch is touched during the sliding process of the cover plate 20, the cover plate 20 stops sliding, and at this time the feed port is aligned with the rice feed port 201, and the rice metering device starts to deliver rice to the accommodating cavity; so as to realize the linkage between the action of the cover plate 20 and the rice metering device ; The driving component can simultaneously drive the cover plate 20 and the bottom plate 12 to move in opposite directions and during the movement, it can ensure that when the feed port and the rice feed port 201 are connected, the discharge port and the rice discharge port 121 are closed; and when the rice falls into the lunch box, the bottom plate 12 and the cover plate 20 are driven by the driving component, the bottom plate 12 is in a state of closing the discharge port, and the cover plate 20 is in a state of closing the feed port, so as to avoid impurities in the external environment from entering the frame 21 when the rice serving device is in an inoperative state, causing the rice to be unsanitary; it is ensured that the feed port and the rice feed port 201 are connected only when the rice metering device delivers rice to the accommodating cavity, and the discharge port and the rice discharge port 121 can be connected only when there is rice in the frame 21, so as to reduce the contact time between the inside of the frame 21 and the external environment and reduce unnecessary pollution.

[0040] Based on the above embodiments, see Figure 1 The driving component includes: a motor 3, a driving gear 4, a first gear 2, and a second gear 6; the motor 3 rotates the driving gear 4, and the first gear 2 and the second gear 6 are respectively arranged on both sides of the driving gear 4 and are engaged with the driving gear 4; the first gear 2 and the second gear 6 can respectively drive the cover plate 20 and the bottom plate 12 to slide in opposite directions.

[0041] Specifically, the driving component includes: a driving gear 4 connected to the motor 3, the first gear 2 and the second gear 6 are both meshed with the driving gear 4, the first gear 2 is used to move the cover plate 20, and the second gear 6 is used to drive the base plate 12 to move; the first gear 2 is installed on the first threaded screw 1, and the second gear 6 is installed on the second threaded screw 5; the thread rotation directions of the first threaded rod and the second threaded rod are opposite, the first transmission rod 25 and the second transmission rod 7 respectively cooperate with the first threaded rod and the second threaded rod to achieve driving; the first transmission rod 25 is connected to the first slider 22, the first slider 22 is installed on the first guide rail 23, the first guide rail 23 is set on the first guide rail support 24, and the first slider 22 can slide in the horizontal direction along the first guide rail 23; one end of the cover plate 20 is connected to the first slider 22, and the other end is connected to the second slider 19, the second slider 19 is installed on the second guide rail 17, the first The second guide rail 17 is fixed by a second guide rail support 18, and the second slider 19 can slide in the horizontal direction along the second guide rail 17; the second transmission rod 7 is connected to the third slider 11, the third slider 11 is installed on the third guide rail 10, and the third guide rail 10 is set on the third guide rail 10 support, and the third slider 11 can slide in the horizontal direction along the third guide rail 10; one end of the base plate 12 is connected to the third slider 11, and the other end is connected to the fourth slider 13, the fourth slider 13 is installed on the fourth guide rail 14, and the fourth guide rail 14 is fixed by the fourth guide rail support 15, and the fourth slider 13 can slide in the horizontal direction along the fourth guide rail 14; this embodiment adopts the method of simultaneously driving the first gear 2 and the second gear 6 by the motor 3 to realize the reverse linkage of the cover plate 20 and the base plate 12. Compared with the method of directly driving the first gear 2 and then driving the second gear 6 through the first gear 2, the primary transmission is more accurate than the secondary transmission in transmission and is more convenient to use.

[0042] Based on the above embodiment, Figure 4 A scraper 211 is provided inside the frame 21 for scraping off rice stuck to the side wall of the frame 21.

[0043] It should be noted that the scraper 211 can automatically work when the material outlet is aligned with the rice outlet 121 to scrape off the rice remaining on the inner wall of the frame 21; the scraper 211 can be driven mechanically or electrically controlled to achieve the rice scraping action, and the shape of the scraper 211 is not limited to the frame shape provided in the figure of this embodiment.

[0044] In the actual automatic rice-serving process, rice is sticky and generally there is a situation where rice sticks to the inside of the frame 21. If the rice retained on the inner wall of the frame 21 is not removed, the rice remaining in the frame 21 will become cold, affecting the dining experience of the next user. In addition, excessive stickiness will affect the accuracy of rice supply. Therefore, setting a scraper 211 can avoid the above problems.

[0045] Based on the above embodiments, see Figure 7 The scraper 211 includes: a transverse portion 2112 and a longitudinal portion 2111. The transverse portion 2112 and the longitudinal portion 2111 are connected, and their cross-section has an "L"-shaped structure. The outer side surfaces of the longitudinal portion 2111 and the transverse portion 2112 are both matched with the inner wall of the frame 21.

[0046] The transverse portion 2112 and the longitudinal portion 2111 are both annular structures; the transverse portion 2112 has a certain width and widens toward the center of the frame 21, and is spliced ​​with the longitudinal portion 2111. The transverse portion 2112 and the longitudinal portion 2111 are an integral structure, and the transverse portion 2112 will not excessively hinder the rice from entering the frame 21. The longitudinal portion 2111 and the transverse portion 2112 are spliced, and their cross section has an "L"-shaped structure. The longitudinal portion 2111 is used to hang the rice stuck on the inner wall of the frame 21, and the transverse portion 2112 is widened because when the thickness of the longitudinal portion 2111 is too thin, the rice will pass over the longitudinal portion 2 111 causes incomplete scraping of rice, so a horizontal portion 2112 is provided to ensure that the rice does not pass over the vertical portion 2111 from below and stick to the upper position of the vertical portion 2111 again; the horizontal portion 2112 alone can also achieve the function of scraping rice, but the fit between the scraper 211 and the inner wall of the frame 21 is relatively loose. If there is no fixing device, the scraper 211 is easy to tilt inside the frame 21, which will affect the effect of the scraper 211 in scraping rice; the cross-section of the scraper 211 at any position in this solution has an "L"-shaped structure, which can fit well with the inner wall of the frame 21, and has a certain fixing effect on the placement angle of the scraper 211.

[0047] Based on the above embodiment, a scraper driving assembly 212 is further included for enabling the scraper 211 to reciprocate along the inner wall of the frame 21 between the top and the bottom.

[0048] When the rice outlet 121 on the bottom plate 12 is connected to the material outlet of the frame 21, the scraper 211 moves downward to scrape off the rice and then rises back to its original position to ensure that all the rice in the frame 21 can fall into the lunch box.

[0049] Based on the above embodiments, see Figure 5 、 6The scraper driving assembly 212 includes: a pull rope 2121, a return spring 2122, a connecting plate 2123, a support plate 2124, a counterweight 2125, and a guide hole 2126; the guide hole 2126 is provided on the side wall of the frame 21, and the accommodating cavity can be connected to the outside of the frame 21 through the guide hole 2126; one end of the connecting plate 2123 is connected to the scraper 211, and the other end is located outside the frame 21, and the connecting plate 2123 can slide along the guide hole 2126; a support plate 2124 is provided at the bottom end of the side of the frame 21, and a through hole is provided on the support plate 2124; the pull rope 2121 One end of the pull rope 2121 is connected to the connecting plate 2123, and the other end of the pull rope 2121 is connected to the counterweight part 2125. The pull rope 2121 passes through the through hole on the support plate 2124, and the counterweight part 2125 is located on the side of the support plate 2124 away from the connecting plate 2123. The counterweight part 2125 can enter the rice outlet 121 of the bottom plate 12 and return to the upper surface of the bottom plate 12 from the rice outlet 121; the reset spring 2122 is sleeved on the pull rope 2121, and one end of the reset spring 2122 is connected to the connecting plate 2123, and the other end is connected to the support plate 2124.

[0050] It should be noted that: the scraper drive assembly 212 is arranged on both sides of the frame 21, located on the left and right sides in the length direction of the base plate 12; the guide hole 2126 is strip-shaped and vertically arranged, and the width of the guide hole 2126 should be small enough to prevent rice from leaking out of the guide hole 2126; one end of the connecting plate 2123 is connected to the scraper 211, and the other end extends to the outside of the frame 21 and the area of ​​its end is widened to ensure the stability of the return spring 2122 when compressed; the lower end of the return spring 2122 is connected to the support plate 2124, and the area of ​​the support plate 2124 is larger than the radial width of the return spring 2122; the pull rope 2121 is provided instead of a rod-shaped structure because the pull rope 2121 is deformable and the pull rod can only remain straight and cannot make the counterweight part 2125 automatically return to the top of the base plate 12.

[0051] The specific implementation process of the scraper drive assembly 212 is as follows:

[0052] When the rice outlet 121 is completely aligned with the discharge port, the compacted rice automatically falls into the lunch box under the action of gravity, and the counterweight 2125 presses down to scrape off the rice stuck to the inner wall of the frame 21, and the counterweight 2125 moves upward partly under the action of the return spring 2122; after the bottom plate 12 moves in the opposite direction, the counterweight 2125 is connected by a pull rope 2121, and when the support plate 2124 is located above the solid area of ​​the bottom plate 12, the pull rope 2121 has an upward pulling force on the counterweight 2125 under the action of the return spring 2122, and at this time, the counterweight 2125 can be pulled out of the rice outlet 121. When the pull rope 2121 is pulled above the bottom plate 12, the return spring 2122 loses the compression force generated when the counterweight part 2125 pulls down the connecting plate 2123, and the return spring 2122 returns to its natural state. At this time, the scraper 211 returns to its original position; the bottom of the inner wall of the frame 21 is provided with a limiting device for preventing the scraper 211 from separating from the frame 21; therefore, the scraper drive assembly 212 in the embodiment of the present invention can be linked with the reciprocating sliding process of the bottom plate 12, so as to scrape the rice, without the need for an additional control device, and the movement of the bottom plate 12 is directly used to open and close the scraper drive assembly 212; compared with adding another scraper device, this embodiment only needs to add the scraper drive assembly 212 to achieve the function of scraping the rice away, and can be linked with the movement of the bottom plate 12 provided in this embodiment, which simplifies the control method compared with separate control.

[0053] It should be noted that if the elasticity of the return spring 2122 is directly increased and installed on the side of the frame, the counterweight part 2125 can be directly returned to the top of the bottom plate under the rebound of the return spring 2122, but there will be a problem that the scraper 211 has a short sliding stroke in the frame 21, especially the bottom of the frame 21 may not be scraped. This solution can avoid this problem.

[0054] Based on the above embodiment, the projection of the frame 21 on the bottom plate 12 can be completely located within the range where the rice outlet 121 is located.

[0055] This ensures that the counterweight portion 2125 can smoothly fall into the area of ​​the rice outlet 121 when the bottom plate 12 slides.

[0056] Based on the above embodiment, a curling structure 122 is provided at the edge of the rice outlet 121 of the bottom plate 12 , and the curling structure is rolled in a direction away from the frame 21 .

[0057] It should be noted that the curling structure can be replaced by a roller, as long as it can reduce the obstruction of the edge of the rice outlet when the counterweight part 2125 returns to the top of the bottom plate 12.

[0058] See also Figure 3 The curling structure 122 is arranged on the side where the counterweight part 2125 returns from the rice outlet 121 to the top of the bottom plate 12; to prevent the counterweight part 2125 from being obstructed by the edge of the rice outlet 121 when returning to the top of the bottom plate 12; the curling structure 122 plays a certain supporting and guiding role when the counterweight part 2125 enters the top of the bottom plate 12.

[0059] Based on the above embodiments, see Figure 5 The pull rope 2121 and the counterweight portion 2125 are an integrally formed structure; the surface of the counterweight portion 2125 is smooth.

[0060] The surface of the counterweight portion 2125 is set to be smooth, which can prevent the counterweight portion 2125 from being stuck at the edge of the rice outlet 121; for example, the embodiment provided Figure 5 The teardrop-shaped counterweight part 2125 used in the invention has a surface that can fit well with the curling structure 122 so that the counterweight part 2125 can slide smoothly onto the top of the bottom plate 12; the pull rope 2121 and the counterweight part 2125 are set to an integrally formed structure in order to prevent the node between the pull rope 2121 and the counterweight part 2125 from breaking easily, or the existence of a protrusion that will hinder the sliding of the counterweight part 2125, and the pull rope 2121 and the counterweight part 2125 can be set to a smooth transition.
