[0027] The utility model embodiment is described below in conjunction with the drawings.

[0028] A kind of raw rice transport mechanism, including first transport mechanism 1, bulk grain scale 2, first bucket elevator 3 and buffer mechanism 4;The first transport mechanism 1, the bulk grain scale 2, the first bucket elevator 3 and the buffer mechanism 4 are sequentially connected, the first transport mechanism 1 is connected with the bottom of external rice tank 5 discharge port, the buffer mechanism 4 is connected with the inlet of external rice steamer 6;

[0029] The buffer mechanism 4 includes housing 41, inclined bottom plate 43, push block 44 and first driver 441, the inside of the housing 41 is equipped with buffer cavity 42, the inclined bottom plate 43 is obliquely arranged at the bottom of the housing 41, and the upper plate surface of the inclined bottom plate 43 is used to receive the material falling through the buffer cavity 42, and blocks the material from moving downward, the high end of the inclined bottom plate 43 and the housing 41 form a discharge port 45;Push block 44 is reciprocally slidably arranged on the upper plate surface of the inclined bottom plate 43 towards the discharge port 45, the reciprocating movement of the push block 44 is used to push the material on the inclined bottom plate 43 to the discharge port 45 output;The first driver 441 is electrically connected with the bulk grain scale 2, and the first driver 441 is used to drive the push block 44 to reciprocate along the upper plate surface of the inclined bottom plate 43.

[0030] As Figure 1 The first transport mechanism 1 moves the raw rice in the raw rice tank 5 to the bulk grain scale 2, the bulk grain scale 2 adjusts the feeding amount and discharges to the first bucket elevator 3, the first bucket elevator 3 moves the raw rice to the high position buffer mechanism 4, and the raw rice is uniformly put into the rice steamer 6 at constant speed through the buffer mechanism 4.

[0031] Conventional rice steamer 6 can only accumulate raw rice at the inlet of rice steamer 6, and when the raw rice below moves forward, it falls under the action of gravity to fill the vacancy, as the rice steamer 6 is relatively humid, it is easy to cause the inlet to be blocked, causing uneven feeding.

[0032] By adding a bulk grain weigher 2, it's possible to determine whether the actual steaming speed meets the required process speed. Simultaneously, the speed of the rice steamer 6 can be adjusted based on the feeding amount of the bulk grain weigher 2. Furthermore, the addition of a buffer mechanism 4 makes the feeding speed more precise, allowing the conveying mechanism to coordinate with the speed of the rice steamer 6 in delivering raw rice. This results in higher steaming efficiency and reduced steaming time. It also solves the problems of inaccurate feeding amount control: too little feeding leads to low steaming efficiency, while too much feeding causes raw rice to clog the inlet of the rice steamer 6, resulting in uneven distribution and difficulty in even cooking.

[0033] like Figure 2 As shown, in a specific embodiment, the first driver 441 is a stepper motor, which can drive the push block 44 to move along the inclined bottom plate 43 according to the speed set by the bulk grain scale 2. When the raw rice fills the buffer chamber 42, the push block 44 moves at a constant speed from the lower end to the higher end of the inclined bottom plate 43, and pushes the raw rice out of the discharge port 45 at a constant speed and in a quantitative manner. When the push block 44 moves to the maximum distance, the first driver 441 drives the push block 44 to quickly reset. This cycle is repeated to achieve the effect of accurately controlling the feeding speed of raw rice.

[0034] Preferably, the buffer mechanism 4 further includes a second driver 471 and a gate 47. The upper surface of the inclined bottom plate 43 is provided with a push cavity 46 in the shape of a straight elongated hole. The push cavity 46 communicates with the buffer cavity 42. The gate 47 is disposed between the push cavity 46 and the buffer cavity 42. The second driver 471 is used to open and close the gate 47. The push surface of the push block 44 matches the cross section of the push cavity 46 in the direction perpendicular to the surface of the inclined bottom plate 43.

[0035] like Figure 2 As shown, when the buffer chamber 42 is filled with raw rice, the second actuator 471 opens the gate 47 located between the buffer chamber 42 and the pushing chamber 46. The raw rice falls and fills the pushing chamber 46 under the action of gravity. After 2 seconds, the second actuator 471 closes the gate 47, and the pushing block 44 pushes the raw rice in the pushing chamber 46 out at a set speed. By closing the gate 47, the movement direction of the raw rice in the pushing chamber 46 is restricted, further improving the feeding accuracy.

[0036] In one embodiment, the buffer mechanism 4 is linked to the rice steamer 6. During the process of the push block 44 pushing raw rice to the discharge port 45, the rice steamer 6 slowly pushes the material inside forward to facilitate the uniform filling of raw rice later. During the process of the push block 44 resetting from the discharge port 45 to the bottom of the inclined bottom plate 43, the rice steamer 6, in cooperation with the buffer mechanism 4, pauses the pushing of its internal material to avoid the raw rice from forming uneven accumulation. When the push block 44 resets and pushes raw rice again, the rice steamer 6 continues to push the material inside.

[0037] Preferably, the inclined bottom plate 43 is provided with a plurality of blocks, and the plurality of blocks of the inclined bottom plate 43 are arranged in a circumferential direction to form an inverted multi-faceted pyramid structure.

[0038] In a more preferred embodiment, the plurality of gates 47, the pushing cavities 46 and the pushing blocks 44 are arranged to work in turn to realize continuous and accurate discharging, and the rice steaming machine 6 continuously pushes the materials in the rice steaming machine 6 to make the steaming more uniform and the production efficiency higher.

[0039] In an embodiment, four inclined bottom plates 43 are provided, and the inclined bottom plates 43 are in a triangular plate structure. The four triangular plates form a right quadrangular pyramid with the bottom surface upward. Each of the inclined bottom plates 43 is provided with a pushing cavity 46, and the pushing cavity 46 is arranged along the middle line of the inclined surface opposite to the apex of the bottom surface of the right quadrangular pyramid. The four pushing blocks 44 push the raw rice outward and upward from the middle of the bottom surface of the right quadrangular pyramid to the discharging port 45.

[0040] Preferably, the housing 41 is further provided with a funnel cavity 48 below the pushing cavity 46, and the funnel cavity 48 is arranged in communication with the pushing cavity 46. The funnel cavity 48 is used to receive the materials output through the discharging port 45, and the lower portion of the funnel cavity 48 is provided with a discharging port 49.

[0041] After the pushing block 44 pushes the raw rice out, the raw rice falls along the inner wall of the funnel cavity 48 under the action of gravity and leaves the buffer mechanism 4. In this way, the raw rice is not directly pushed and dropped out of the rice steaming machine 6 by the pushing block 44.

[0042] Preferably, the first conveying mechanism 1 includes a first scraper conveyor 11, a belt conveyor 12, a second scraper conveyor 13 and a second bucket elevator 14. The first scraper conveyor 11 is connected to the discharging port of the rice tank 5. The first scraper conveyor 11, the belt conveyor 12, the second scraper conveyor 13 and the second bucket elevator 14 are connected in sequence. The second bucket elevator 14 is connected to the inlet of the bulk grain scale 2.

[0043] In a specific embodiment, the first scraper conveyor 11 is arranged 10 cm below the discharge port of the rice tank 5. When the first scraper conveyor 11 is not started, the raw rice is accumulated on the first scraper conveyor 11 to block the discharge port, and the raw rice cannot continuously fall from the rice tank 5. When the first scraper conveyor 11 is started, the accumulated raw rice is taken away by the scraper, and the raw rice continuously falls from the rice tank 5 and is transferred to the belt conveyor 12. The horizontally arranged belt conveyor 12 transfers the material to the second scraper conveyor 13 near the second bucket elevator 14. The raw rice is transferred to the second bucket elevator 14 through the second scraper conveyor 13, and the second bucket elevator 14 sends the raw rice into the bulk grain scale 2. Because the granular raw rice is prone to rolling and difficult to be lifted in the transmission process, and the conventional bucket elevator is too low in efficiency in horizontal transportation, the three transmission modes of belt, scraper and bucket elevator are used in cooperation, and the bulk grain scale 2 is connected and controlled in linkage, so that the problem that the raw rice is difficult to be used in cooperation with the bulk grain scale 2 in the transmission process is solved.

[0044] Preferably, the chute 7 is further included, the chute 7 is connected to the outlet of the buffer mechanism 4 and the inlet of the rice steaming machine 6, the chute 7 is a hollow square pipeline, and the width of the chute 7 is greater than or equal to the discharge port 49 of the buffer mechanism 4.

[0045] The square chute 7 is adopted, so that the raw rice in the buffer mechanism 4 can smoothly and uniformly fall onto the conveyor belt of the rice steaming machine 6, and the raw rice is prevented from accidentally falling outside the equipment.

[0046] Preferably, the air extraction pipe 8 and the air extraction pump are further included, the inlet of the air extraction pipe 8 is arranged between the buffer mechanism 4 and the rice steaming machine 6, and the air extraction pump is used to extract the steam generated by the rice steaming machine 6 through the air extraction pipe.

[0047] In a specific embodiment, the inlet of the air extraction pipe 8 is arranged at the middle part of the chute 7, the steam is extracted by the air extraction pipe 8 and the air extraction pump, the steam is prevented from entering the buffer mechanism 4, and the problem that the raw rice in the buffer mechanism 4 is damp and clumped and blocked is avoided.

[0048] Preferably, the filter screen 10 is further included, the filter screen 10 is arranged on the first transmission mechanism 1, and the filter screen 10 is used to screen and remove the clumped raw rice.

[0049] The raw rice is prone to moisture absorption, deterioration and clumping. In the transmission process, the clumped and deteriorated raw rice can be effectively removed by the filter screen 10, and the product quality is improved. In a specific embodiment, the first transmission mechanism 1 includes the first scraper conveyor 11, the belt conveyor 12 and the second scraper conveyor 13, the filter screen 10 is arranged obliquely between the belt conveyor 12 and the second scraper conveyor 13, the raw rice falls from the end of the belt conveyor 12 to the filter screen 10, the clumped raw rice is intercepted by the filter screen 10 and slides along the inclined screen surface to be removed.
