[0026] In the exemplary embodiments, as Figures 1-3As shown, the embodiment provides a rice drying device, which comprises a drying box 1, the top of the drying box 1 is provided with a feeding pipe 2, the bottom is provided with a discharging pipe 3, and a first intercepting plate 4 is also obliquely connected between the inner top surface and one side surface of the drying box 1, a plurality of first intercepting holes 5 are arranged on the first intercepting plate 4, the first intercepting plate 4 divides the inside of the drying box 1 into an intercepting chamber 6 located obliquely upward and a drying chamber 7 located obliquely downward, the feeding pipe 2 is communicated with the drying chamber 7 to guide the rice into the drying chamber 7; a guide hopper 8 is also fixedly connected to the lower end of the drying box 1 and located in the drying chamber 7 and divides the drying chamber 7, the discharging pipe 3 extends into the drying box 1 and is connected to the lower end of the guide hopper 8, drying is carried out in the drying chamber 7, and after drying is completed, the rice is guided out through the guide hopper 8 and the discharging pipe 3; a hot air fan 9 is also arranged in the drying box 1, the hot air fan 9 has an air outlet pipe 10 connected to the discharging pipe 3, hot air is guided into the guide hopper 8 through the discharging pipe 3 and then blown into the drying chamber 7 upward, a second intercepting plate 11 capable of dividing the guide hopper 8 is also inserted on the drying box 1, a plurality of second intercepting holes 12 are arranged on the second intercepting plate 11, and all the second intercepting holes 12 are located in the guide hopper 8, the second intercepting plate 11 can allow the hot air to pass through and also allow the rice to pass through, during drying, the hot air fan 9 is started first to guide hot air into the drying chamber 7 (it should be noted that a first cover body 13 is connected to the outlet end of the discharging pipe 3, and the hot air cannot be guided out of the discharging pipe 3), and then the rice is guided in, which can be guided in a small amount at a time so that the rice does not all fall on the second intercepting plate 11, in order to facilitate observation of the inside of the drying chamber 7, a transparent window located on the drying box 1 can also be added; the drying box 1 is also fixedly connected with a guide air pipe 14 and a guide pipe 15 communicated with the intercepting chamber 6, and the guide air pipe 14 and the guide pipe 15 are located at the upper end and the lower end of the intercepting chamber 6 respectively, and a filter screen 16 is also arranged on the communication part of the guide air pipe 14 and the intercepting chamber 6; during the drying process, part of the rice after drying may have relatively light particles, this part of the rice will pass through the first intercepting plate 4 and then enter the intercepting chamber 6, but due to the arrangement of the filter screen 16, this part of the rice will be intercepted in the intercepting chamber 6, which can be discharged through the guide pipe 15 later (a second cover body 17 similar to the first cover body 13 is arranged on the outlet end of the guide pipe 15, and similarly, the first cover body 13 and the second cover body 17 can be threadedly connected, and the guide pipe 15 is in a closed state during drying), and the main part of the chaff, debris and other impurities guided out of the rear of the guide air pipe 14 are the chaff, debris and other impurities that can pass through the filter screen 16, which do not need to be screened, saving a part of time, and thus the overall efficiency can be improved to a certain extent.

[0027] As Figures 1-3As shown, in a further scheme, the first intercepting hole 5 can be a transverse strip hole with a larger width to facilitate the passage of impurities and lighter rice, and the transverse state also makes it difficult to return to the drying box 1 after passing through. In particular, the first mounting plate 18 is fixedly connected to the inner top surface of the drying box 1, the second mounting plate 19 is fixedly connected to the inner side wall, and the first intercepting plate 4 is connected between the first mounting plate 18 and the second mounting plate 19, so that the lower end of the intercepting chamber 6 is separated from (not communicated with) the drying chamber 7, so that the intercepted rice does not return to the drying chamber 7 after falling to the lower end of the intercepting chamber 6; the second intercepting hole 12 can also be a strip hole, which can be transverse or longitudinal, with a smaller width to avoid the rice falling directly below, but the hot air can pass through smoothly.

[0028] As shown in the further scheme, Figures 1-3 the first inclined guide plate 20 and the second inclined guide plate 21 are respectively fixedly connected to the first mounting plate 18 and the second mounting plate 19, the first inclined guide plate 20 and the second inclined guide plate 21 both have a lower end extending obliquely downward away from the first intercepting plate 4, and the lower end is away from the inner wall of the drying box 1, wherein the first inclined guide plate 20 is closer to the feeding pipe 2, and the first inclined guide plate 20 can block the hot air when it blows upward to prevent the rice from returning to the feeding pipe 2, and at the same time, it can also guide the hot air to move towards the first intercepting plate 4. In order to make the hot air pass through the first intercepting plate 4 more smoothly and enter the air guide pipe 14, an air extractor can also be connected to the end of the air guide pipe 14 for assistance. The second inclined guide plate 21 blocks the hot air to change the direction of movement, and a small number of through holes can also be added to the second inclined guide plate 21 to allow part of the hot air to pass through, so that the rice can also smoothly contact the hot air on the second inclined guide plate 21. Further, the first inclined hole plate 22 and the second inclined hole plate 23 are detachably connected to the inner wall of the drying box 1 and staggered with the first inclined guide plate 20 and the second inclined guide plate 21, and the first inclined hole plate 22 and the second inclined hole plate 23 are both provided with third intercepting holes, and the first inclined hole plate 22 and the second inclined hole plate 23 both have a lower end extending obliquely downward towards the first intercepting plate 4. The first inclined guide plate 20, the first inclined hole plate 22, the second inclined guide plate 21 and the second inclined hole plate 23 can make the rice move downward in an S-shaped path in the drying chamber 7, and the efficiency of contacting the hot air is also better, thus achieving better drying effect. In particular, the diameters of the third intercepting holes and the through holes are smaller than the particle size of the rice, so that the rice cannot pass through, and the hot air can pass through smoothly. At the same time, the lower ends of the first inclined hole plate 22 and the second inclined hole plate 23 are away from the inner wall of the drying chamber 7, ensuring a gap for the rice to move downward smoothly.

[0029] As shown in the further scheme, Figures 1-4As shown, in a more detailed scheme, the higher end of the first inclined hole plate 22 and the second inclined hole plate 23 is respectively detachably connected with the inner wall of the drying box 1 through the connecting plate 24, and the drying box 1 is further provided with an opening and closing door 25 located between the first inclined hole plate 22 and the second inclined hole plate 23, the opening and closing door 25 is used to open and close the drying chamber 7, so as to facilitate the maintenance of the internal components of the drying box 1, and the transparent window can also be provided on the opening and closing door 25; and the connecting plate 24 can be connected by bolts 26, which is convenient for disassembly and subsequent maintenance.

[0030] As shown, in a more detailed scheme, the higher end of the first inclined hole plate 22 and the second inclined hole plate 23 is respectively detachably connected with the inner wall of the drying box 1 through the connecting plate 24, and the drying box 1 is further provided with an opening and closing door 25 located between the first inclined hole plate 22 and the second inclined hole plate 23, the opening and closing door 25 is used to open and close the drying chamber 7, so as to facilitate the maintenance of the internal components of the drying box 1, and the transparent window can also be provided on the opening and closing door 25; and the connecting plate 24 can be connected by bolts 26, which is convenient for disassembly and subsequent maintenance.
