DETAILED DESCRIPTION

[0019] 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.

[0020] Example: Figures 1 to 11 As shown, this embodiment discloses a new type of rice beating machine, including a machine body 1, in which a rice delivery mechanism 2 is arranged, the rice delivery mechanism 2 includes a rice loosening bucket 21 and at least two rice delivery screws 22 rotatably arranged in the rice loosening bucket 21, the rice delivery screw 22 includes a screw shaft 221, a screw spiral blade 222 which is arranged on the outer peripheral side of the screw shaft 221 and extends axially and is spirally distributed, one end of the screw shaft 221 is provided with a rice stirring block 223, and among the two rice delivery screws 22, the screw spiral blade 222 on one rice delivery screw 22 is staggered with the screw spiral blade 222 on the other rice delivery screw 22, and the two rice delivery screws 22 are spaced and arranged side by side in the rice loosening bucket 21 so that the screw spiral blades 222 of the two rice delivery screws 22 partially overlap in axial projection. In this embodiment, the screw spiral blades 222 of the two rice delivery screws 22 are staggered and overlapped, so that the two rice delivery screws 22 can cooperate with each other to provide double driving force in the rice pushing area when pushing rice, so that the rice delivery mechanism 2 can push rice more powerfully, effectively improve the efficiency of picking rice and improving the efficiency of rice output, and reduce the probability of rice adhering to the rice delivery screw 22, which is convenient for placing more rice in the rice loosening bucket 21, and is also more conducive to pushing the rice in the rice loosening bucket 21 clean, fully meeting the user's use needs. In addition, by setting the rice stirring block 223, it is convenient for the rice delivery screw 22 to provide a larger driving force at the end position of the rice delivery screw 22, stir up the rice accumulated at the end of the rice delivery screw 22, and then be pushed out by the front screw spiral blade 222, which is more conducive to draining the rice in the rice loosening bucket 21.

[0021] Furthermore, the rice stirring block 223 is located outside the screw spiral blade 222 and close to the side wall of the rice loosening bucket 21. Since the amount of rice accumulated in the rice loosening bucket 21 near the end of the rice delivery screw 22, that is, near the side wall of the rice loosening bucket 21, is generally large and requires greater force, the rice compacted at the bottom can be stirred up by arranging the rice stirring block 223 at this position, and then partially pushed out by the front screw spiral blade 222, which is more conducive to draining the rice. The rice stirring block 223 is as close to the inner wall of the rice loosening bucket 21 as possible without affecting the rotation of the rice delivery screw 22, so as to avoid the phenomenon of rice hiding in dead corners.

[0022] Furthermore, the rice delivery mechanism 2 further comprises a rice delivery feather rod 3, which is used to preliminarily loosen the rice poured into the rice loosening bucket 21 so that the rice delivery screw 22 can push the rice out of the rice loosening bucket 21. The rice delivery feather rod 3 is arranged in the rice loosening bucket 21 and above the rice delivery screw 22, and the rice delivery feather rod 3 comprises a feather rod shaft 31, a rice scraping tooth group 4 arranged at one end of the feather rod shaft 31, and a feather rod spiral blade 5 arranged at the other end of the feather rod shaft 31. The rice scraping tooth group 4 can facilitate the loosening of the rice, and the feather rod spiral blade 5 can assist the rice delivery screw 22, and cooperate with each other to push the rice out of the rice loosening bucket 21 when the rice machine needs to divide the rice.

[0023] Furthermore, the rice-scraping tooth group 4 includes a plurality of rice-scraping tooth rows 41 distributed circumferentially along the feather rod shaft 31, and the rice-scraping tooth rows 41 include a plurality of rice-scraping tooth plates 42 distributed at intervals along the axial direction. Specifically, the rice-scraping tooth plates 42 are in the shape of a right-angled trapezoid or a triangle. An inclined surface 43 perpendicular to the axial direction is provided on the rice-scraping tooth plate 42. In this embodiment, the rice-scraping tooth plate 42 adopts a plate-like structure. Compared with the long and small scraping teeth on the existing rice-delivering feather rod, the rice-scraping tooth plate 42 of the present design is in the shape of a plate, which has a larger rice-scraping area and can better loosen the rice. Moreover, the plurality of rice-scraping tooth rows 41 are distributed at intervals along the circumferential direction, and each rice-scraping tooth row 41 complements the flipping space of the previous rice-scraping tooth row 41 when rotating, so that rice can be scraped without dead angles in the circumferential direction.

[0024] Furthermore, in two adjacent rice-cleaving tooth rows 41, the inclined surface 43 of the rice-cleaving tooth plate 42 of one rice-cleaving tooth row 41 faces one end of the feather rod shaft 31, and the inclined surface 43 of the rice-cleaving tooth plate 42 of the other rice-cleaving tooth row 41 faces the other end of the feather rod shaft 31. In this embodiment, the inclined surfaces of the two adjacent rice-cleaving tooth rows 41 in the circumferential direction face opposite directions, and can respectively generate opposite forces in the axial direction on the rice, and can cyclically generate separation force on the rice during rotation, thereby improving the effect of loosening the rice.

[0025] Furthermore, a rice hopper group 5 is provided at the rice outlet end of the rice delivery mechanism 2 in the machine body 1, and the rice hopper group 5 includes two rice hoppers 51 arranged at intervals, and a bearing surface 511 for bearing rice is provided on the inner side of the rice hopper 51, and a first inner convex portion 512 is provided on the bearing surface 511, and a second inner convex portion 211 is provided on the inner side of the rice loosening hopper 21. The design of the inner convex portion reduces the plane area of ​​rice and rice pieces contacting the rice hopper 51 and the rice loosening hopper 21, which is conducive to the rice being separated from the rice hopper 51 and the rice loosening hopper 21.

[0026] Furthermore, in order to facilitate automatic opening and closing of the rice hopper group 5 so that the rice maker can perform rice dispensing operations, a rice hopper transmission device 6 for driving the rice hopper group 5 to open or close is provided in the machine body 1.

[0027] Furthermore, the rice bucket transmission device 6 includes a rice bucket support frame 61, on which a connecting rod 62 connected to the rice bucket 51 for driving the rice bucket 51 to flip is rotatably connected, and a pressing plate 63 is provided at one end of the connecting rod 62 away from the rice bucket 51. A rotatable transmission member 64 for abutting against the pressing plate 63 and a driving motor 65 for driving the transmission member 64 to flip are provided in the body 1. An eccentric wheel 66 for driving the transmission member 64 to flip is provided on the driving shaft of the driving motor 65. A first return spring 67 connected to the pressing plate 63 is provided on the rice bucket support frame 61, and a second return spring 68 connected to the transmission member 64 is provided on the driving motor 65. The driving shaft of the driving motor 65 is connected to the eccentric wheel 66. The eccentric wheel 66 contacts the transmission member 64 so as to drive the transmission member 64 to be pressed down. One end of the transmission member 64 abuts against the pressing plate 63. When the transmission member 64 is pressed down, the pressing plate 63 is driven to flip downward, thereby driving the corresponding connecting rod 62 and the rice bucket 51 to flip and open. At this time, the first return spring 67 and the second return spring 68 are both in a tensioned state. When the driving motor 65 drives the eccentric wheel 66 to release the transmission member 64, the transmission member 64 and the pressing plate 63 are no longer subjected to the pressing force. The first return spring 67 and the second return spring 68 pull the transmission member 64 and the pressing plate 63 to reset respectively, thereby causing the corresponding connecting rod 62 and the rice bucket 51 to flip and close again.

[0028] Furthermore, a weighing detector 7 is provided in the machine body 1 and is in contact with the rice hopper support frame 61. The weight of the rice entering the rice hopper 51 is detected by the weighing detector 7, and when the rice reaches a certain value, the driving motor 62 drives the rice hopper 51 to open. The weighing detector 7 is arranged on the plate of the machine body 1, and the rice hopper support frame 61 is arranged at the upper end of the weighing detector 7 and is in contact with the weighing detector 7, so that the weighing detector 7 can accurately detect the weight of the rice entering the rice hopper 51.

[0029] Furthermore, the rice delivery mechanism 2 also includes a rotatable dividing rod 8, which is arranged at one end of the rice delivery screw 22. The dividing rod 8 is used to cooperate with the rice delivery screw 22 to deliver the separated rice in the rice loosening hopper 21 to the rice hopper group 5. The rice delivery screw 22 pushes the separated rice to the dividing rod 8, and the dividing rod 8 delivers the rice to the rice hopper group 5 so that the rice making machine can perform rice dividing operations. The dividing rod 8 includes a rice scraping boss 81 arranged on its outer peripheral side for scraping rice and an anti-sticking boss 82 for preventing rice from adhering to the dividing rod 8. The rice scraping boss 81 is used to separate the rice accumulated in the rice loosening hopper 21 to prevent re-agglomeration, and to enhance the force for scraping rice, thereby improving the rice delivery efficiency. The outer peripheral side of the distribution rod 8 is provided with a plurality of groups of rice-stealing boss groups 83 distributed at intervals along its circumferential direction, and each group of rice-stealing boss groups 83 includes a plurality of rice-stealing bosses 81 distributed at intervals along the axial direction of the distribution rod 8, and each group of rice-stealing boss groups 83 is distributed obliquely around the axis of the distribution rod 8.

[0030] The working principle of this embodiment is as follows: In this embodiment, the screw spiral blades 222 of the two rice delivery screws 22 are staggered and overlapped, so that the two rice delivery screws 22 can cooperate with each other to provide double driving force in the rice pushing area when pushing rice, so that the rice delivery mechanism 2 can push rice more powerfully, effectively improve the efficiency of picking rice and improving the efficiency of rice output, and reduce the probability of rice adhering to the rice delivery screw 22, which is convenient for placing more rice in the rice loosening bucket 21, and is also more conducive to pushing the rice in the rice loosening bucket 21 clean, fully meeting the user's use needs. In addition, by setting the rice stirring block 223, it is convenient for the rice delivery screw 22 to provide a larger driving force at the end position of the rice delivery screw 22, stir up the rice accumulated at the end of the rice delivery screw 22, and then be pushed out by the front screw spiral blade 222, which is more conducive to draining the rice in the rice loosening bucket 21.
