It is not only an important supplement to people's daily diet, but also an important means to ensure dietary balance.

[0003] For example, the utility model disclosed in the publication number CN213719812U discloses a mixing device for konjac rice and coarse grains rice, comprising a base, a support arm is arranged above the top edge of the base, the support arm and the base are connected and arranged by a fixed shaft 1, a support ring is arranged directly above the base, the support ring and the support arm are connected and arranged by a fixed shaft 2, a barrel body is installed in the middle of the support ring, a barrel mouth is provided at the top of the barrel body, a mixing and stirring mechanism is provided at the top of the barrel mouth, a motor 2 is installed at the bottom of the barrel body, a water outlet is provided at the side wall of the barrel body near the bottom end, and a connecting assembly is provided at the bottom of the barrel body; curved scrapers are provided on the outer walls of both sides of the connecting assembly. The mixing device for konjac rice and coarse grains rice, because the lower end of the curved scraper is closely fitted with the bottom end of the barrel body, and the side surface of the vertical scraper is closely fitted with the inner wall of the barrel body, the konjac rice powder and auxiliary materials on the bottom of the barrel and the lower inner wall of the barrel can be scraped off to prevent them from adhering to the barrel wall, thereby facilitating the full mixing of konjac rice powder and coarse grains.

[0004] When the above device is in use, the design of structures such as curved scrapers and stirring rods prevents the raw materials from sticking to the inner wall during stirring, thereby improving the mixing efficiency and cleaning effect.

Moreover, large-particle raw materials are placed in the mixing box together with small-particle raw materials, and may directly sink to the bottom of the box, thereby causing uneven mixing. Therefore, a raw material mixing and stirring device for grain rice is proposed to solve the problems raised in the background technology. Summary of the invention

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figures 1 to 7As shown, the present invention provides a raw material mixing and stirring device for coarse grain rice, comprising a stirring barrel 1, a downstairs funnel 2 and a first motor 3 are fixedly connected to the top of the stirring barrel 1, a first gear 4 is fixedly connected to the output shaft end of the first motor 3, a rotating drum 5 and a circular baffle 8 are movably connected inside the stirring barrel 1, a guide groove 6 is provided on the inner wall of the rotating drum 5, a second gear 7 is fixedly connected to the top of the rotating drum 5, a first convex rod 9 is annularly arranged at 90 degrees on the outer wall of the circular baffle 8, a first filter assembly 10 and a second filter assembly 11 are movably connected inside the circular baffle 8, a limiting plate 14 is movably connected to one side of the stirring barrel 1, a threaded rod 13 is threadedly connected to the middle part of the limiting plate 14, a moving assembly 12 is movably connected to one end of the threaded rod 13 close to the first filter assembly 10, a second motor 15 is fixedly connected to the bottom of the stirring barrel 1, and a stirring rod 16 is fixedly connected to the output shaft end of the second motor 15.

[0029] The guide groove 6 is in a corrugated shape, so that when the rotating drum 5 rotates, the first protruding rod 9 is driven to move up and down along the trajectory of the guide groove 6, and then the circular baffle 8 is driven to vibrate through the first protruding rod 9, and the bottom of the circular baffle 8 is blocked by the first filter plate 1002 and the second filter plate 1102, so that when the circular baffle 8 moves, the miscellaneous grains on the first filter plate 1002 and the second filter plate 1102 are driven to vibrate, so that the miscellaneous grains with smaller particles fall into the mixing barrel 1, while the miscellaneous grains with larger particles remain on the first filter plate 1002 and the second filter plate 1102, thereby preventing the miscellaneous grains with larger particles from directly falling into the bottom of the mixing box and causing uneven mixing.

[0030] like Figures 2 to 3 , Figures 5 to 7 As shown, the first filter assembly 10 includes a first rotating shaft 1001, the outer wall of the first rotating shaft 1001 is fixedly connected to a first filter plate 1002, the inner wall of the first rotating shaft 1001 is annularly provided with a first inclined groove 1003 at an angle of 180 degrees, and the arc of the first inclined groove 1003 is 60 degrees. The second filter assembly 11 includes a second rotating shaft 1101, the outer wall of the second rotating shaft 1101 is fixedly connected to a second filter plate 1102, the inner wall of the second rotating shaft 1101 is annularly provided with a first inclined groove 1003 at an angle of 180 degrees, and the arc of the first inclined groove 1003 is 60 degrees. A second inclined groove 1103 is provided, and the second inclined groove 1103 has the same degree as the first inclined groove 1003, but is in opposite directions. There is a gap between the first filter plate 1002 and the second filter plate 1102 and the inner wall of the circular baffle 8. The first filter plate 1002 and the second filter plate 1102 form a disc in the initial state and cover the bottom of the circular baffle 8. The first filter plate 1002 and the second filter plate 1102 both rotate with the moving component 12 as the axis.

[0031] The first inclined slot 1003 and the second inclined slot 1103 are oriented in opposite directions, so that when the limit rod 1201 moves, the first rotating shaft 1001 and the second rotating shaft 1101 are driven to rotate in two directions, and then the first filter plate 1002 and the second filter plate 1102 are driven to rotate respectively through the two. The rotated first rotating shaft 1001 and the second filter plate 1102 release the obstruction on the bottom of the circular baffle 8, so that the coarse grain rice with larger particles on the two falls into the mixing barrel 1 through the rotated inclined surface, thereby facilitating the addition of the coarse grain rice with larger particles into the mixing barrel 1, thereby balancing the material distribution during the mixing process and improving the mixing effect.

[0032] like Figures 2 to 3 , Figures 5 to 7 As shown, the opposite ends of the first rotating shaft 1001 and the second rotating shaft 1101 both penetrate the outer wall of the circular baffle 8 and extend to the outside of the circular baffle 8. The first filter assembly 10 and the second filter assembly 11 leave a gap from the top of the stirring rod 16. The moving assembly 12 includes a limiting rod 1201. The outer wall of the limiting rod 1201 is respectively provided with a second protruding rod 1202 and a third protruding rod 1203 in a circular shape and 180 degrees. The second protruding rod 1202 is movably clamped in the inside of the first inclined groove 1003, and the third protruding rod 1203 is movably clamped in the inside of the second inclined groove 1103. The limiting rod 1201 is composed of a round rod and a square plate. When the threaded rod 13 rotates, the square plate is used to circumferentially limit the round rod. One end of 13 away from the moving component 12 passes through the outer wall of the mixing barrel 1 and extends to the outside of the mixing barrel 1. The inner wall of the mixing barrel 1 is provided with a sliding groove for limiting the limit plate 14 in the vertical direction. When the threaded rod 13 rotates, it drives the limit rod 1201 to move toward the limit plate 14. When the limit rod 1201 moves, it drives the second protruding rod 1202 and the third protruding rod 1203 to slide along the trajectories of the first inclined groove 1003 and the second inclined groove 1103 respectively. After the limit rod 1201 moves, it drives the first filter plate 1002 to rotate counterclockwise through the first rotating shaft 1001. After the limit rod 1201 moves, it drives the second filter plate 1102 to rotate clockwise through the second rotating shaft 1101.

[0033] Gaps are left between the first filter plate 1002 and the second filter plate 1102 and the inner wall of the circular baffle 8. The purpose is that if the first filter plate 1002 and the second filter plate 1102 are in close contact with the inner wall of the circular baffle 8, the two may collide or rub against the inner wall of the circular baffle 8 during rotation, thereby causing wear between the two and the inner wall of the circular baffle 8, thereby affecting the normal operation of the device. Appropriate gaps can prevent this from happening.

[0034] like Figures 1 to 4As shown, the first gear 4 is meshed with the second gear 7, the guide groove 6 is corrugated, the circular baffle 8 is located inside the rotating drum 5, the four first protruding rods 9 are movably connected to the inside of the guide groove 6, the bottom of the inner cavity of the mixing barrel 1 is inclined, a visual window is provided in the middle of the outer wall of the mixing barrel 1, and a discharge port is provided on the outer wall of the mixing barrel 1. When the rotating drum 5 rotates, the first protruding rod 9 is driven to slide along the trajectory of the guide groove 6, and the circular baffle 8 is moved up and down reciprocatingly. The inner wall of the mixing barrel 1 is provided with a straight groove 17 that cooperates with the first protruding rod 9. The straight groove 17 is used to circumferentially limit the first protruding rod 9 when the rotating drum 5 rotates.

[0035] A visual window is provided on the surface of the mixing barrel 1, and its function is to facilitate the operator to intuitively observe the stirring conditions of the grains inside the mixing barrel 1, including the mixing state of the grains, the uniformity of the stirring, etc. By observing the stirring state of the grains, the operator can more accurately judge whether the stirring has achieved the predetermined effect, thereby avoiding unnecessary long-term stirring, thereby improving the stirring efficiency. The bottom of the inner cavity of the mixing barrel 1 is inclined, thereby facilitating the discharge of the stirred grain rice raw materials, thereby preventing them from accumulating at the bottom of the inner cavity of the mixing barrel 1.

[0036] The working principle and use process of the present invention are as follows: the operator pours the grain rice into the mixing barrel 1 through the downstairs funnel 2, and then starts the first motor 3, thereby driving the first gear 4 to rotate, and then the first gear 4 is meshed with the second gear 7, so that the second gear 7 drives the rotating drum 5 to rotate. While the rotating drum 5 rotates, it drives the four first protruding rods 9 to slide along the trajectory of the guide groove 6. At this time, since the straight groove 17 limits the circumferential position of the first protruding rod 9, when the rotating drum 5 rotates, the first protruding rod 9 can only drive the circular baffle 8 to reciprocate up and down along the trajectory of the guide groove 6, thereby generating vibration. While the circular baffle 8 moves, since the first filter component 10 and the second filter component 11 are both in contact with the circular The baffle plate 8 is movably connected, so when the circular baffle plate 8 moves up and down, it will drive the first filter component 10, the second filter component 11 and the moving component 12 therein to move at the same frequency, thereby causing the miscellaneous grains and rice falling on the first filter screen plate 1002 and the second filter screen plate 1102 to form a continuous jumping motion, and then the miscellaneous grains and rice with smaller and more uniform sizes fall into the interior of the mixing barrel 1 through the pores of the first filter screen plate 1002 and the second filter screen plate 1102, while the miscellaneous grains and rice with larger sizes are retained on the first filter screen plate 1002 and the second filter screen plate 1102. Then, the operator starts the second motor 15, thereby driving the stirring rod 16 to rotate, and then stirring the miscellaneous grains and rice falling into the interior of the mixing barrel 1 to make them fully mixed;

[0037] When the mixed grain rice with uniform size inside the mixing barrel 1 is mixed, the operator drives the limit rod 1201 to move toward the limit plate 14 by rotating the threaded rod 13. While the limit rod 1201 moves, it drives the second protruding rod 1202 and the third protruding rod 1203 to slide along the tracks of the first inclined groove 1003 and the second inclined groove 1103 respectively. At this time, since the first inclined groove 1003 and the second inclined groove 1103 are in opposite directions, the limit rod 1201 drives the first rotating shaft 1001 and the second rotating shaft 1101 to rotate in opposite directions after moving. Subsequently, the first The filter plate 1002 rotates counterclockwise driven by the first rotating shaft 1001, and the second filter plate 1102 rotates clockwise driven by the second rotating shaft 1101. After the first filter plate 1002 and the second filter plate 1102 rotate, the obstruction to the bottom of the circular baffle 8 is released. Subsequently, the coarse grain rice with larger particles on the top of the two falls into the interior of the mixing barrel 1 through the gap after rotation. At this time, the second motor 15 is started again, thereby driving the stirring rod 16 to mix the coarse grain rice with larger particles with the mixed coarse grain rice again, thereby improving the overall mixing uniformity of the device.
