Description

Technical Field

[0001] The utility model relates to the technical field of rice selection, in particular to a drum-type rice grading and selection machine. Background Art

[0002] Rice, also known as "rice", is divided into three types: indica rice, japonica rice, and glutinous rice. Rice is flat in nature and sweet in taste. It has the functions of nourishing the stomach, strengthening the essence and will, improving hearing and eyesight, harmonizing the five internal organs, promoting blood circulation, relieving restlessness, quenching thirst, and stopping diarrhea. Rice is very nutritious and is one of the main foods of the Chinese people. Japonica rice can nourish the spleen, nourish the stomach, nourish and strengthen. Japonica rice porridge has the functions of nourishing the spleen, harmonizing the stomach, and clearing the lungs. It is suitable for people with weak gastrointestinal function after illness, especially those who are thirsty and restless. When choosing rice, the rice can be graded and selected.

[0003] For example, the Chinese utility model patent with announcement number CN214600230U discloses a drum-type rice length grading and selecting device, including a selecting box, a feed box is installed on one side of the selecting box, a connecting hole is opened between the feed box and the selecting box, a rotating plate is opened on the inner wall of one side of the selecting box, a selecting roller is fixedly installed on one side of the rotating plate, an annular plate is fixedly installed on one side of the selecting roller, the annular plate is rotatably installed in the connecting hole, a rotating motor is fixedly installed on one side of the feeding box, the output shaft of the rotating motor extends into the feeding box and is fixedly installed with a rotating rod, one end of the rotating rod is fixedly installed on the rotating plate, a spiral push plate is fixedly installed on the rotating rod, and a groove is opened on the inner wall of the connecting hole;

[0004] The above scheme has the following problems: the device can be used to load rice, and the selection of rice of different lengths can be conveniently performed by rotating the selection drum, and the selection drum can be conveniently cleaned, and the rice can be prevented from being stuck on the selection drum; however, the device uses an entire grading drum inside the selection drum to grade the rice during use. Since no interval is provided between the drums, it is easy to cause the rice to be graded and mixed under the action of inertia during the grading process. At the same time, when the device grades and selects a large amount of rice, the rice is easy to accumulate on the top of the drum. When the larger-sized rice covers the bottom, the small-sized rice grains on the top cannot be graded and selected, which seriously affects the grading effect.

[0005] Therefore we propose a drum type rice grading and selecting machine to solve the above-mentioned problems. Utility Model Content

[0006] The utility model aims to provide a drum type rice grading and selecting machine to solve the problem that the rice grading and selecting machines on the market currently have a mixing phenomenon when grading rice, as mentioned in the above background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a drum-type rice grading and selecting machine, comprising a fixed seat and a drum body; the drum body is installed on the fixed seat through a plurality of fixed brackets; the drum body is of cylindrical design; the interior of the drum body is divided into three parts: a primary rolling bin, a secondary rolling bin and a tertiary rolling bin; and the rolling bins are separated from each other by partitioning plates; the primary rolling bin, the secondary rolling bin and the tertiary rolling bin are distributed from left to right; the primary rolling bin is the bin with the highest grading accuracy; a rolling channel is arranged on the inner wall of the drum body; the rolling channel is evenly distributed in a spiral shape inside the drum body, and the rolling channel is fixedly connected to the drum body;

[0008] As the preferred technical solution of the utility model, a first-level discharge port, a second-level discharge port and a third-level discharge port are respectively designed below the first-level rolling bin, the second-level rolling bin and the third-level rolling bin; and the length of the discharge port is the same as the length of the rolling bin; material blocking curtains are arranged at the end faces of the first-level discharge port, the second-level discharge port and the third-level discharge port; and the material blocking curtains are movably connected to the discharge port.

[0009] As the preferred technical solution of the utility model, a feed port is provided on the end face of the roller body near the first-level rolling bin; the feed port is connected with the roller body; the feed port is fixed above the fixed seat through a fixed bracket; the feed port is of funnel design; a blanking plate is provided inside the feed port; the blanking plate is embedded in the feed port; a scraper plate is provided directly above the blanking plate; the scraper plate is movably connected to the blanking plate; a movable shaft is provided at the center of the scraper plate; the movable shaft is fixedly connected to the scraper plate; the top end of the movable shaft is connected to the shaft of the rotating motor; the rotating motor is located at the center of the feed port.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The device is provided with a multi-stage rolling bin and a rolling channel. When in use, the rice transported into the device through the feed port rolls inside the drum along the rolling channel under the rotation of the drum body. While rolling, the rice falls to the corresponding multi-stage discharge ports below through the gaps in the multi-stage rolling bin according to the size of the particles, so that the device can grade and select the rice through the rolling of the rolling bin during use, and can also transport the rice inside the drum body through the rolling channel to prevent the rice from being blocked inside the rolling barrel;

[0015] 2. The device is provided with a scraper plate and a drop plate. While conveying the rice to the inside of the drum body through the feed port, the feeding speed of the rice is controlled by the half-open and half-closed design of the drop plate, so as to prevent excessive rice conveyed at one time from accumulating inside the drum body and affecting the grading effect. The rotation of the scraper plate above the drop plate can scrape the rice in the closed part above the drop plate to the open part, so as to prevent the rice from being blocked at the feed port. Thus, when the device is in use, the grading accuracy can be avoided due to excessive rice supply, and at the same time, the grading efficiency can be prevented from being blocked at the feed port.
