Description

Technical Field

[0001] This utility model relates to the field of rice production and processing technology, specifically to a rice lifting device for rice production and processing. Background Technology

[0002] Rice production and processing refers to the systematic industrial process of transforming paddy rice into finished rice, encompassing the entire process from raw material cleaning to finished product packaging. Its core steps include: paddy pretreatment (screening, destoning, magnetic separation, etc. to remove impurities), hulling (removing the husk by rolling with rubber rollers), paddy-brown separation (screening unhulled paddy for reprocessing), milling and polishing (multiple sand or iron rollers to grind the surface of the rice grains, removing bran powder and enhancing gloss), color sorting and grading (using photoelectric technology to remove yellow grains, diseased grains, and other discolored grains), and packaging and storage (weighing according to quality grade and packaging with moisture-proof materials).

[0003] A search revealed that CN222024037U discloses a rice lifting device for rice production and processing, comprising a base plate, a vertical plate fixedly connected to the top surface of the base plate, and a groove inside the vertical plate. A lead screw is rotatably connected within the groove, and the lead screw is connected to a transmission mechanism. A slider is threaded onto the lead screw, and a support plate is fixedly connected to the side of the slider via a connecting rod. A driven shaft is rotatably connected to the top surface of the support plate, and the driven shaft is connected to another transmission mechanism. The inclined surface of the bottom of the housing enables automatic feeding. Then, an electric push rod drives a limiting plate to limit and block the discharge port, thereby controlling the discharge speed. No flipping is required, resulting in lower costs. Furthermore, the guide plate guides the rice, reducing the probability of rice spilling outside the processing container and increasing accuracy.

[0004] However, when the above-mentioned device is in use, during the process of lifting rice, the shell containing rice is lifted to the required position and then unloaded. After unloading, the shell needs to be lowered back to the low position and then refilled with rice. This process causes the lifting of rice to be interrupted, making it impossible to maintain the continuous lifting of rice, thus affecting the lifting efficiency of rice production. Utility Model Content

[0005] The purpose of this utility model is to provide a rice lifting device for rice production and processing, in order to solve the problem mentioned in the background art that, during the process of lifting rice, the rice-filled shell is lifted to the required position and then unloaded. After unloading, the shell needs to be lowered back to the low position and then refilled with rice. This process causes the rice lifting to be interrupted, making it impossible to maintain the continuous lifting of rice, thereby affecting the lifting efficiency of rice production.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a mounting base plate, on the upper end of which a lifting chamber is fixedly mounted. A drive motor is fixedly mounted on the outer wall of the upper end of the lifting chamber. The inner drive shaft of the drive motor is connected to an upper drive shaft via a coupling. An upper pulley is fixedly mounted on the outer curved surface of the upper drive shaft. A vertical groove is opened through the lower end of the lifting chamber. A limit lifting plate is vertically and movably connected to the inner wall of the vertical groove. A lower drive shaft is rotatably connected to the middle of the limit lifting plate via a rotating shaft. A lower pulley is fixedly mounted on the outer curved surface of the middle of the lower drive shaft. A feed hopper for discharging rice into the bottom of the lifting chamber is fixedly connected to the lower end of the lifting chamber. A lifting belt is driven by the outer curved surfaces of the upper and lower pulleys. A lifting bucket for lifting the rice is fixedly mounted on the outer end of the lifting belt. A discharge port is fixedly connected to the upper end of the lifting chamber.

[0007] An adjusting shaft is rotatably connected to the lower outer side of the discharge port via a rotating shaft. An adjusting groove is fixedly installed on the outer curved surface of the adjusting shaft. An electric telescopic rod is rotatably connected to the upper outer side of the lifting chamber via a pin. The telescopic part of the upper end of the electric telescopic rod is rotatably connected to an adjusting rod via a pin.

[0008] Preferably, the upper outer side of the limiting lifting plate is vertically rotatably connected to an adjusting screw via a rotating shaft, and a U-shaped adjusting frame is fixedly installed on the lower outer wall of the lifting chamber.

[0009] Preferably, the upper end of the adjusting screw is threaded through to the middle of the U-shaped adjusting frame, and the outer curved surface of the upper end of the adjusting screw is threaded with a fastening nut for tightening the adjusting screw.

[0010] Preferably, there are several lifting buckets, which are symmetrically distributed around the outer end of the lifting belt, and the discharge port is inclined downward.

[0011] Preferably, the inner side of the upper end of the adjusting groove is rotatably connected to the outer side of the lower end of the discharge port via a rotating shaft.

[0012] Preferably, the upper end of the electric telescopic rod is inclined outward.

[0013] Preferably, the adjusting rod is fixedly installed on the outer end of the adjusting shaft.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] When the drive motor is turned on, this utility model drives the upper transmission shaft to rotate. When the upper transmission shaft rotates, it works with the lower pulley to drive the lifting belt to rotate and convey. When the lifting belt rotates and conveys, it drives the lifting bucket to rotate and convey continuously. When the lifting bucket rotates and conveys continuously, it lifts and conveys the rice at the bottom of the lifting bin upwards. When the lifting bucket lifts and conveys the rice to the top of the lifting bin, it flips and throws the rice inside the lifting bucket toward the discharge port, so that the rice is discharged outwards through the discharge port and the regulating trough, thereby achieving the function of facilitating continuous lifting and conveying of rice.

[0016] This invention also features a mechanism where, when the adjusting screw moves up and down, it drives the limiting lifting plate to move linearly up and down along the inner wall of the vertical slide groove. This linear movement of the limiting lifting plate, in turn, drives the lower transmission shaft to move linearly up and down. This, in turn, drives the lower pulley to move linearly up and down, which in turn adjusts the tension of the lifting belt, preventing slippage. Simultaneously, the invention controls the extension and retraction of the electric telescopic rod. When the electric telescopic rod extends or retracts, it drives the adjusting shaft to rotate via the adjusting rod. This rotation of the adjusting shaft causes the adjusting groove to swing up and down, facilitating the adjustment of the material discharge angle. Attached Figure Description

A vertical slide groove 6 is provided through the lower end of the lifting chamber 2. A limit lifting plate 7 is vertically fitted and movably connected to the inner wall of the vertical slide groove 6. A lower drive shaft 8 is rotatably connected to the middle of the limit lifting plate 7 via a rotating shaft. A lower pulley 9 is fixedly mounted on the outer curved surface of the middle of the lower drive shaft 8. The upper outer side of the limit lifting plate 7 is vertically rotatably connected to the lower drive shaft 8 via a rotating shaft. An adjusting screw 10 is connected to the upper end of the lifting chamber 2. A U-shaped adjusting frame 11 is fixedly installed on the lower outer wall of the lifting chamber 2. The upper end of the adjusting screw 10 is threaded through and connected to the middle of the U-shaped adjusting frame 11. A fastening nut for tightening the adjusting screw 10 is threaded on the outer curved surface of the upper end of the adjusting screw 10. A feeding hopper 12 for discharging rice into the bottom of the lifting chamber 2 is fixedly connected to the lower end of the lifting chamber 2. The upper pulley 5 and the lower pulley 9 are connected to the lifting belt 13 through the outer curved surface. A lifting bucket 14 for lifting rice is fixedly installed on the outer end of the lifting belt 13. There are several lifting buckets 14, which are symmetrically distributed with respect to the outer end of the lifting belt 13. A discharge port 15 is fixedly connected to the upper end of the lifting chamber 2. The discharge port 15 is inclined downwards.

[0024] An adjusting shaft 16 is rotatably connected to the outer side of the lower end of the discharge port 15 via a rotating shaft. An adjusting groove 17 is fixedly installed on the outer curved surface of the adjusting shaft 16. The inner side of the upper end of the adjusting groove 17 is rotatably connected to the outer side of the lower end of the discharge port 15 via a rotating shaft. An electric telescopic rod 18 is rotatably connected to the outer side of the upper end of the lifting chamber 2 via a pin. The upper end of the electric telescopic rod 18 is inclined outward. An adjusting rod 19 is rotatably connected to the upper telescopic part of the electric telescopic rod 18 via a pin. The adjusting rod 19 is fixedly installed on the outer end of the adjusting shaft 16.

[0025] Working principle: In use, this utility model discharges rice into the bottom of the lifting chamber 2 through the feeding hopper 12. When the rice is discharged into the bottom of the lifting chamber 2, the drive motor 3 is turned on by control. When the drive motor 3 is turned on, it will drive the upper transmission shaft 4 to rotate. When the upper transmission shaft 4 rotates, it will cooperate with the lower pulley 9 to drive the lifting belt 13 to rotate and convey. When the lifting belt 13 rotates and conveys, it will drive the lifting bucket 14 to rotate and convey continuously. When the lifting bucket 14 rotates and conveys continuously, it will lift and convey the rice at the bottom of the lifting chamber 2 upward. When the lifting bucket 14 lifts and conveys the rice to the top of the lifting chamber 2, it will flip and throw the rice inside the lifting bucket 14 towards the discharge port 15, so that the rice is discharged outward through the discharge port 15 and the regulating groove 17, thereby realizing the function of facilitating continuous lifting and conveying of rice.

[0026] By rotating the fastening nut to loosen it, the adjusting screw 10 is rotated. When the adjusting screw 10 rotates, it moves up and down due to the force generated by the bolt connection with the U-shaped adjusting frame 11. When the adjusting screw 10 moves up and down, it drives the limiting lifting plate 7 to move linearly up and down along the inner wall of the vertical slide 6. When the limiting lifting plate 7 moves linearly up and down, it drives the lower transmission shaft 8 to move linearly up and down. When the lower transmission shaft 8 moves linearly up and down, it drives the lower pulley 9 to move linearly up and down. When the lower pulley 9 moves linearly up and down, it drives the tension adjustment of the lifting belt 13, thereby adjusting the tension of the lifting belt 13 and preventing slippage. At the same time, the electric telescopic rod 18 is extended and retracted by controlling it. When the electric telescopic rod 18 extends and retracts, it drives the adjusting shaft 16 to rotate through the adjusting rod 19. When the adjusting shaft 16 rotates, it drives the adjusting groove 17 to swing up and down, thereby facilitating the adjustment of the discharge angle of the adjusting groove 17.
