Technical Field

[0001] This utility model relates to the technical field of wheat grain screening, specifically a device for removing and optimizing heterogeneous grains in a drum sorting machine. Background Technology

[0002] Wheat kernels refer to the grains on wheat plants, which are used to grind into flour and are an important raw material for food processing. In order to improve the quality of food, it is necessary to remove foreign seeds from wheat kernels. During the removal process, appropriate drum separators can be used to optimize the wheat kernels.

[0003] As disclosed in CN219581023U, a drum screening device includes: a drum screen, a support plate, a fixing ring, and an electrode plate. The support plate includes a left support plate and a right support plate arranged opposite to each other. The drum screen is positioned between the left and right support plates via the fixing ring, which is sleeved around the outer periphery of the drum screen and fixedly connected to the left and right support plates. The electrode plate includes an upper electrode plate and a lower electrode plate. The upper electrode plate is horizontally positioned above the drum screen, and the lower electrode plate is horizontally positioned below the drum screen. The left support plate, right support plate, upper electrode plate, and lower electrode plate surround the drum screen to form a box structure. This invention can improve the dust removal rate during screening and simultaneously suppress dust pollution during the screening process.

[0004] However, existing technologies have problems such as the need to continuously and repeatedly add materials to the drum during screening, which is cumbersome and inconvenient to adjust the material feeding rate. In addition, the collection of removed impurities is also inconvenient. For example, the comparative patents listed above have this problem.

[0005] To address this issue, we propose an optimized device for removing foreign seeds in a drum sorting machine. Utility Model Content

[0006] The purpose of this utility model is to provide an optimized device for removing foreign seeds in a drum separator, so as to solve the problems mentioned in the background art, which require continuous and repeated addition of materials to the drum during screening, which is cumbersome, inconvenient to adjust the material feeding rate, and difficult to collect the removed impurities.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a drum sorting machine for removing and optimizing foreign seeds, comprising a fixed frame and an inclined screening drum disposed on the upper end of the fixed frame;

[0008] Also includes:

[0009] The feeding cylinder is located on the left side of the fixed frame, and a feeding cylinder is fixedly connected to the lower end of the feeding cylinder. At the same time, the lower end of the feeding cylinder extends into the screening drum.

[0010] The feeding cylinder is fitted with a baffle in the middle, and the feeding cylinder and the baffle are fixed by a limiting mechanism set at the left end of the baffle.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-7 .

[0033] To address the problems in existing technologies where material needs to be continuously and repeatedly added to the drum during screening, resulting in cumbersome operation, inconvenience in adjusting the material feeding rate, and difficulty in collecting the removed impurities, this solution provides a drum separator for removing and optimizing foreign seeds. The device comprises a fixed frame 1, an inclined screening drum 2 positioned on top of the fixed frame 1, a feeding cylinder 8 located on the left side of the fixed frame 1, and a feeding cylinder 9 fixedly connected to the lower end of the feeding cylinder 8. The lower end of the feeding cylinder 9 extends into the screening drum 2, and a baffle 10 is inserted into the middle of the feeding cylinder 9. The feeding cylinder 9 and the baffle 10 are fixed together by a limiting mechanism located on the left side of the baffle 10. A fixed box 16 for collecting waste material is located in the middle of the fixed frame 1, positioned below the screening drum 2, and the width of the fixed box 16 is greater than the diameter of the screening drum 2.

[0034] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the fixing frame 1 is placed on the ground. The upper end of the fixing frame 1 is provided with a left fixing plate 3, and the left side of the left fixing plate 3 is fixedly connected to the feeding cylinder 8. First, the wheat grains to be screened are added to the feeding cylinder 8. At the same time, the lower end of the feeding cylinder 8 is fixedly connected to the feeding cylinder 9. The middle part of the feeding cylinder 9 is telescopically connected to the baffle 10. Combined with the setting of the limiting mechanism, the limiting mechanism is composed of movable blocks 11 fixed on the front and rear sides of the left end of the baffle 10, fixed posts 12 inserted into the middle of the movable blocks 11, movable frames 13 sleeved on the outside of the movable blocks 11, springs 14 set between the movable frames 13 and the movable blocks 11, and fixed blocks 15 fixedly connected to the front and rear ends of the movable blocks 11.

[0035] By pulling the movable frame 13 upwards, the movable frame 13 slides between itself and the fixed block 15, compressing the spring 14 and causing it to elastically deform. At this point, the upper end of the movable frame 13 moves out of the fixing hole at the upper end of the fixed post 12, thus releasing the restriction between the movable block 11 and the fixed post 12. Then, by pulling the baffle 10 to the left, the baffle 10 causes the movable block 11 to slide between itself and the fixed post 12. Simultaneously, the baffle 10 moves within the feeding cylinder 9, thus releasing the blockage on the feeding cylinder 9. Wheat grains in the feeding cylinder 8 are fed downward into the screening cylinder 2 through the feeding cylinder 9. The size of the opening of the feeding cylinder 9 can be adjusted by the distance the baffle 10 moves in the feeding cylinder 9, thereby adjusting the feeding rate of the wheat grains. Then, the movable frame 13 is released directly. At this time, the spring 14 returns to its elastic deformation, pushes the movable frame 13 downward and engages in the fixing hole at the corresponding position on the upper end of the fixed column 12, limiting the movement between the movable block 11 and the fixed column 12, and fixing the baffle 10.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, wheat grains enter the screening drum 2. The motor 5 on the upper end of the right fixed plate 4 is started. The motor 5, through meshing gears 6 and a circular rack 7, drives the screening drum 2 to rotate slowly in the middle of the left fixed plate 3 and the right fixed plate 4. The screening drum 2 is tilted, and the wheat grains move slowly to the right under gravity, being screened by the screening drum 2. The rejected foreign grains fall through the holes of the screening drum 2 into the fixed box 16. A collection container is located at the right end of the screening drum 2 to collect the selected wheat grains. Furthermore, after use, combined with... Figure 8 As shown, by rotating the fixing bolt 17, the limiting position between the fixing box 16 and the fixing frame 1 is released, and then the fixing box 16 is pulled to the left to move it out of the fixing frame 1, thereby facilitating the cleaning of the waste collected in the fixing box 16.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
