DETAILED DESCRIPTION

[0022] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] See also Figure 1-Figure 5 A filtering device for easily removing a filter screen comprises a base 1, a filter box 2 for filtering rice is fixedly installed on the top of the base 1 by bolts, a feed port 3 in the shape of an inverted trapezoid is arranged on the top of the filter box 2, slide grooves 4 are symmetrically opened near the top of the inner walls on the left and right sides of the filter box 2, a slider 5 connected to the slide groove 4 for sliding up and down is installed inside the slide groove 4, a guide plate 6 arranged obliquely is fixedly connected to one side of the slider 5 by screws, a vibration motor 7 installed on the inner wall of the filter box 2 is arranged at the bottom of the guide plate 6, two oppositely arranged and different lengths are fixedly installed at the bottom of the two guide plates 6 close to each other by bolts. A card plate 8 is provided, and a plurality of filter screens 9 distributed at equal intervals horizontally are slidably inserted between the two card plates 8. Specifically, card blocks 91 that cooperate with the card slot 81 are provided on the left and right side walls of the filter screen 9. The filter screen 9 is equal to the width of the card plate 8, and the length of the filter screen 9 is equal to the distance between the two card plates 8, so as to avoid the situation that the card plate 8 cannot be engaged with the filter screen 9, which would cause disadvantages of the scheme. The top ends of the two card plates 8 are flush and the bottom ends are connected by an inclined panel 11. A first discharge port 10 is provided at the lower end of the longer card plate 8, and the front end of the filter box 2 is open and a sealing door 14 for replacing the filter screen 9 is hinged.

[0025] Specifically, the sealing door 14 is hinged to the filter box 2 by a hinge, and a handle 15 is fixedly installed on the outer wall of the end of the sealing door 14 away from the hinge. The handle 15 is provided with a threaded pattern for increasing the contact friction. The sealing door 14 allows the internal structure of the filter box 2 to be directly disassembled by opening the sealing door 14. The threaded pattern can increase the friction of the handle 15, making it less likely to slip when the sealing door 14 is opened.

[0026] Specifically, a plurality of springs 13 are provided at the bottom end of the slide groove 4, and the tops of the plurality of springs 13 on the same side are fixedly mounted on the bottom of the slider 5. The springs 13 are provided to buffer the slider 5, thereby avoiding serious wear inside the machine.

[0027] Specifically, a vertical plate is integrally formed at one end of the guide plate 6 connected to the slider 5. The length of the vertical plate is greater than the height of the slide 4. The vertical plate blocks the notch of the slide 4 to prevent rice from entering the slide 4 during use and causing blockage in the slide 4, thereby rendering the machine unusable. The purpose of the tight fit is to prevent the slider 5 from slipping out of the slide 4.

[0028] Specifically, the card plate 8 is placed vertically, and a plurality of card slots 81 for clamping the filter screen 9 are provided on the opposite side walls of the two card plates 8. The front and rear side walls of the card plate 8 and the filter screen 9 are tightly fitted with the inner wall of the sealing door 14 and the rear inner wall of the filter box 2 respectively, to avoid the filter screen 9 being too small, causing the rice to fall directly through the gap between the filter screen 9 and the inner wall of the filter box 2, resulting in an unfiltered state. At the same time, it also avoids the filter screen 9 being too large and unable to be installed into the filter box 2, or causing excessive friction and loss.

[0029] Specifically, a second discharge port 12 is provided at the lower end of a side wall of the filter box 2 near the first discharge port 10. The inner bottom surface of the filter box 2 is inclined downward and the bottom end is tangent to the bottom surface of the arc-shaped second discharge port 12. The inner bottom surface of the filter box 2 is polished smooth by a grinder, and the filtered rice is passed into the second discharge port 12 through the inclined surface and slides out from the second discharge port 12, thereby realizing the collection of the filtered rice.

[0030] Specifically, there is at least one filter screen 9, and the mesh sizes of the plurality of filter screens 9 decrease from top to bottom and the mesh size of the bottom layer of filter screens 9 is 3-5 mm. The large-sized sand, gravel, soil and rice are separated by the filter screens 9. The rice is filtered by setting multiple layers of filter screens 9 to reduce the content of sand, gravel and soil. The size of the last layer of filter screens 9 is 3-5 mm, so that the rice can fall onto the inclined panel 11, and the filtered rice is discharged through the first discharge port 10 and the second discharge port 12.

[0031] Specifically, the interface between the first discharge port 10 and the inclined panel 11 is configured to be in a smooth arc shape to prevent rice from getting stuck at the interface and causing waste.

[0032] Specifically, a lead core layer is provided inside the base 1 to improve the stability of the base 1 .

[0033] Working principle: the rice to be filtered is poured into the filter box 2 through the feed port 3 at the upper end of the filter box 2, and the rice is directly poured into the upper end of the card plate 8 and the filter screen 9 through the guide plate 6, and the large particles of sand and gravel mixed in the rice and other impurities are removed through several layers of the filter screen 9, and a first discharge port 10 is provided at the bottom end of the card plate 8 along the end of the inclined panel 11 to deliver the rice to the inclined structure at the bottom of the filter box 2, and the rice is slid out from the second discharge port 12 through the inclined structure, and a sealing door 14 is installed on the outside of the filter box 2 and a handle 15 is provided on the sealing door 14. The handle 15 controls the switch of the sealing door 14. After opening the sealing door 14, the internal filter screen 9 can be directly taken out and cleaned, thereby realizing the function of easy disassembly of the filter screen 9.

[0034] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the concept of the utility model. For example, the above features are replaced with the technical features with similar functions disclosed in the present application (but not limited to) to form a technical solution.
