Abstract
Description
Technical Field
[0001] This utility model relates to the field of rice processing technology, specifically to a drying device that facilitates dust removal. Background Technology
[0002] The earliest methods of drying rice relied on natural sunlight and wind. With the advancement of technology, drying equipment uses hot air as a drying medium. The rice is placed in a drying chamber, and the hot air circulation removes the moisture from the rice.
[0003] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: 1. When the existing equipment dries rice, the lack of a dust removal structure causes dust inside the rice to float everywhere and adhere to the exhaust fan, affecting the cleaning of the equipment; 2. When feeding the existing equipment, workers usually pour large quantities of rice directly from sacks into the machine, causing large amounts of rice to enter and block the spreader. Utility Model Content
[0004] The purpose of this utility model is to provide a drying device that facilitates dust cleaning, thereby solving the problems mentioned in the background art regarding the inconvenience of dust cleaning and the inability to adjust the rice feed flow rate. To achieve the above objective, this utility model provides the following technical solution: a drying device that facilitates dust cleaning, comprising a machine body, a feeding hopper installed at the upper end of the machine body, a servo motor installed on one side of the feeding hopper, a rotating shaft connected to one side of the servo motor, a baffle installed on one side of the rotating shaft, a discharge port provided at the bottom of the machine body, an AC motor installed on one side of the discharge port, a main shaft connected to the upper end of the AC motor, a spreader installed on one side of the main shaft, a protective shell provided on one side of the spreader, a heating shell installed on one side of the machine body, a heating tube installed on the inner wall of the heating shell, an air intake fan provided on one side of the heating tube, a dustproof cotton provided on one side of the air intake fan, a collection box installed on the inner wall of the machine body, an exhaust fan provided on one side of the collection box, a rotating rod installed on one side of the exhaust fan, a brush connected to one side of the rotating shaft, and a filter plate provided on one side of the brush.
[0005] More preferably, the baffle is configured as a rotating structure by the cooperation of a servo motor and a rotating shaft.
[0006] More preferably, the outer surface of the spreader is provided with a plurality of circular sieve holes.
[0007] More preferably, the heating tubes are symmetrically installed about the transverse centerline of the heating shell.
[0008] More preferably, the central axis of the air intake fan coincides with the transverse central axis of the dustproof cotton.
[0009] More preferably, the brush forms a rotating structure through the cooperation of an air outlet fan and a rotating rod.
[0010] More preferably, the filter plates are symmetrically installed about the transverse centerline of the machine body.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] In this invention, a brush and a filter plate are added. When the equipment is in use, the exhaust fan rotates to suck in floating dust. The filter plate blocks and intercepts dust and impurities in the air. At the same time, the brush rotates driven by the exhaust fan to sweep down dust and debris, causing clumps of dust or heavier impurities to fall into the collection box, preventing dust and impurities from flying around inside the machine and affecting subsequent cleaning.
[0013] In this invention, a baffle and a rotating shaft are added. When the equipment is feeding, the servo motor drives the rotating shaft to rotate, which in turn drives the baffle to rotate. The baffle adjusts the opening and closing angle to regulate the flow rate of rice in the feeding hopper, preventing the flow rate from being too fast and causing blockage on the bottom spreader. This allows the rice to be evenly spread on the spreader for uniform drying. Attached Figure Description

[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the baffle 5 forms a rotating structure through the cooperation of the servo motor 3 and the rotating shaft 4. By installing the baffle 5 on one side of the rotating shaft 4, the servo motor 3 drives the rotating shaft 4 to rotate, thereby driving the baffle 5 to rotate. The baffle 5 can adjust the flow rate of rice in the feed hopper 2 by adjusting the opening and closing angle, so as to prevent the rice flow rate from being too fast and causing blockage of the spreader 9.
[0024] In this embodiment, as Figure 5 As shown, the outer surface of the spreader 9 is provided with multiple circular sieve holes; by installing the spreader 9 on one side of the main shaft 8, the AC motor 7 drives the main shaft 8 to rotate, thereby driving the spreader 9 to rotate, so that the spreader 9 can spread the rice evenly and dry the rice evenly.
[0025] In this embodiment, as Figure 4 As shown, the heating tubes 12 are symmetrically installed about the transverse centerline of the heating shell 11; by installing the heating tubes 12 on the inner wall of the heating shell 11, the heating tubes 12 heat the air inside the heating shell 11, thereby heating the air to dry the rice.
[0026] In this embodiment, as Figure 4 As shown, the central axis of the air intake fan 13 coincides with the transverse central axis of the dustproof cotton 14; by installing the air intake fan 13 on one side of the heating shell 11, the air intake fan 13 rotates to blow out the heated air, so that the hot airflow circulates inside the machine body 1, and the hot airflow heats and dries the rice on the spreader 9 by rotating.
[0027] In this embodiment, as Figure 6 As shown, the brush 18 forms a rotating structure through the cooperation of the exhaust fan 16 and the rotating rod 17. By installing the brush 18 on one side of the rotating rod 17, the exhaust fan 16 rotates to drive the rotating rod 17 to rotate, which in turn drives the brush 18 to rotate. This allows the brush 18 to sweep the dust off the filter plate 19 and let the dust fall into the collection box 15 for cleaning and collection.
[0028] In this embodiment, as Figure 6 As shown, the filter plates 19 are symmetrically installed about the transverse centerline of the body 1. By installing the filter plates 19 on one side of the collection box 15, the filter plates 19 allow hot air to pass through through multiple tiny filter holes, while intercepting particles to filter dust in the air and prevent dust from adhering to the exhaust fan 16.
[0029] The usage and advantages of this utility model: This drying equipment, which facilitates dust cleaning, operates as follows:
[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the equipment is first started, and then rice is poured into the feed hopper 2. The heating tube 12 heats the air inside the heating shell 11 to raise the air temperature. At the same time, the intake fan 13 rotates to blow out the heated air, allowing the hot airflow to circulate inside the machine body 1. Then, the servo motor 3 drives the rotating shaft 4 to rotate, which in turn drives the baffle 5 to rotate. The baffle 5 adjusts the opening and closing angle to regulate the flow rate of rice in the feed hopper 2. Simultaneously, the AC motor 7 drives the main shaft 8 to rotate, which in turn drives the spreading plate 9 to rotate, spreading the rice evenly so that the hot airflow can heat the rice evenly. While heating, the exhaust fan 16 rotates to suck in floating dust. The installed filter plate 19 blocks and intercepts the dust and impurities in the air. At the same time, the brush 18 rotates driven by the exhaust fan 16 to sweep down the dust and debris, causing clumps of dust or heavier impurities to fall into the collection box 15 for dust collection.
