[0005] The above technical objectives of the present invention are achieved through the following technical solutions: a rice packaging device, comprising a box body, a feeding port is arranged on the top of the box body, a rice box is arranged on the top of the box body, a drying component is arranged in the rice box, two discharge ports are symmetrically arranged at the bottom of the rice box, a filter plate is arranged below the discharge port, a weighing component is arranged below the filter plate, the weighing component comprises a receiving barrel 1 and a receiving barrel 2, the receiving barrel 1 and the receiving barrel 2 are symmetrically arranged, the bottoms of the receiving barrel 1 and the receiving barrel 2 are both provided with a discharge port, the bottoms of the receiving barrel 1 and the receiving barrel 2 are respectively provided with weight sensors, a rice conveying mechanism is arranged below the weighing component, the rice conveying mechanism comprises a material guide pipe rotatably connected to the bottom of the box body, a vertical pipe in contact with the discharge port, and a driving member, the driving member drives the vertical pipe to switch between the two discharge ports.

[0006] By adopting the above technical solution, the drying component dries the rice in the rice box, opens the discharge port to allow the dried rice to fall into the filter plate, and then falls into the receiving barrel 1 and the receiving barrel 2 after being filtered by the filter plate. The weight sensors arranged at the bottom of the receiving barrel 1 and the receiving barrel 2 detect the weight of the rice. When the required weight is reached, the driving component controls the vertical pipe to contact the discharge port, and the rice packaging bag is supported at the bottom of the guide pipe, thereby finally realizing the packaging of the rice.

[0008] By adopting the above technical solution, rice is fed into the rice packaging bag through the vertical tube, the S-shaped bend tube and the guide tube in sequence, and the driving member drives the S-shaped bend tube to rotate and drives the vertical tube to rotate 180 degrees from the receiving barrel 1 to the receiving barrel 2.

[0009] The present invention is further configured as follows: a movable part for embedding the feeding port is arranged at one end of the vertical tube away from the S-shaped bend, the movable part comprises a cylinder which is sleeved inside the vertical tube and tightly attached to the inner wall of the vertical tube, a ring is fixedly connected to one end of the cylinder away from the vertical tube, a baffle is circumferentially arranged on the outer wall of the vertical tube at one end away from the S-shaped bend, and a spring is fixed between the baffle and the ring.

[0010] By adopting the above technical solution, the movable part can help the vertical pipe and the discharge port to fit more tightly: the ring on the movable part can fit tightly with the discharge port; and the elastic force of the spring gives the ring a certain pressure to make the contact between the ring and the discharge port closer, and the sealing is also guaranteed.

[0011] The present invention is further configured as follows: the feed opening is a truncated cone-shaped opening, the diameter of the feed opening gradually decreases from top to bottom, and an inner slope surface inclined to the center of the box is provided at the inner ring of the circular ring.

[0012] By adopting the above technical solution, the discharge port is a truncated cone-shaped opening, which helps the discharge port to be embedded in the vertical tube, thereby ensuring the sealing when the rice flows; the slope inclined toward the center of the circle at the inner ring of the circular ring can be more closely fitted with the truncated cone-shaped opening of the discharge port, and at the same time, when the rotation is reversed under the control of the driving member, the vertical tube can be more conveniently detached from the discharge port at the bottom of the receiving barrel.

[0013] The present invention is further configured as follows: a downwardly inclined outer slope surface is provided at the outer ring of the circular ring.

[0014] By adopting the above technical solution, the downwardly inclined slope at the outer ring of the circular ring can facilitate the movable part to move to the bottom of the discharge port and engage with the discharge port when the driving part moves the vertical pipe from the bottom discharge port of the receiving barrel one to the bottom discharge port of the receiving barrel two.

[0015] The present invention is further configured as follows: the driving member includes a fixing member and a first motor, the fixing member is fixedly connected to the S-shaped bend pipe, the first motor is vertically arranged, the output end of the first motor is fixedly connected to the fixing member, a mounting frame is arranged at the center of the interior of the box, and the first motor is fixedly connected to the mounting frame.

[0016] By adopting the above technical solution, the first motor is located at the center of the box body, so that the fixing member drives the S-shaped bend pipe to rotate along the center of the box body.

[0017] The present invention is further configured as follows: the drying component includes a second motor fixedly connected to the top center of the box body, the output end of the second motor is fixedly connected to a vertically arranged rotating shaft, the rotating shaft passes through the rice box, a rotating rod is fixedly connected to the rotating shaft, the rotating rod is vertically arranged to the rotating shaft, a scraper is fixedly connected to one end of the rotating rod away from the rotating shaft, the scraper is in contact with the inner wall of the rice box, the rotating rod is hollow inside, a heating rod is arranged inside the rotating rod, and the rotating rod is in contact with the bottom of the rice box.

At the same time, a heating rod is arranged inside the rotating rod. When the rotating rod contacts the rice to make the rice move, the inside of the rice can be dried to prevent moisture from being contained in the rice, which makes the rice moldy after packaging.

[0019] The present invention is further configured as follows: a cam is fixedly connected to the bottom of the rotating rod, the cam is located between the two filter plates and the cam is in contact with the filter plates.

[0020] By adopting the above technical solution, the rotating rod controls the rotation of the cam, so that the tip of the cam is continuously embedded in different filter holes on the filter plate, thereby achieving impact on the filter plate and preventing the filter plate from being blocked.

[0026] 3. In the present invention, the receiving barrel 1 and the receiving barrel 2 respectively receive the rice grains after filtering, and weigh them through the weight sensor arranged at the bottom thereof. The two can weigh rice of different weights respectively without affecting each other. When the S-shaped elbow rotates to the bottom of the receiving barrel of the corresponding weight, the valve in the corresponding discharge port opens, realizing point-to-point precise feeding and avoiding the overflow of rice.
