Description

Technical Field

[0001] This utility model relates to the field of screening technology, specifically a wheat grain impurity removal and screening device. Background Technology

[0002] Wheat is a general term for plants of the wheat family, belonging to the monocotyledonous class and the Poaceae family. As a highly adaptable crop, it is widely cultivated in temperate and subtropical regions across all continents of the world. Its mature caryopsis is rich in nutrients such as carbohydrates and proteins, and can be processed into various staple foods such as flour, noodles, and bread, making it one of the important food crops supporting the human diet. After wheat is harvested from the field, due to factors such as the precision of the harvesting equipment and the field environment, the harvested wheat is often mixed with various impurities such as straw fragments, soil clods, small stones, and weeds. These impurities not only affect the storage quality of wheat, but also interfere with the efficiency of subsequent processing and the quality of the finished product. Therefore, it is necessary to separate the impurities from the qualified wheat through a screening process. However, most wheat screening devices currently on the market rely on electric motors to drive the core components such as screens to remove impurities. While these devices can meet the large-scale screening needs of fixed sites (such as grain purchasing points and processing plants), they have significant limitations in key agricultural production scenarios in the fields: stable power supply is often lacking during field operations, and setting up temporary power supply equipment is not only time-consuming and labor-intensive, but also difficult to achieve due to site conditions. This results in traditional electric screening devices being unable to be used normally during real-time screening in the field. This single driving mode makes it difficult for operators to flexibly choose the screening method according to the actual operation scenario (fixed indoor sites with power supply, temporary field operations without power supply), which not only reduces the applicability of the device, but also brings many inconveniences to the subsequent processing of wheat in agricultural production.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Please see Figures 1 to 2 This utility model provides a technical solution: a wheat grain impurity removal and screening device, including a first support 2 and a second support 3. The top of the first support 2 is provided with a screen plate 1 that can swing left and right. Therefore, when the screen plate 1 swings left and right, it can drive the material on its surface to swing synchronously, thereby effectively trapping large particles in the material on the screen plate 1. A receiving plate 14 that can receive material is provided directly below the screen plate 1. The second support 3 is provided with a driving component that can provide power for the swinging of the screen plate 1. A handle 8 is fixedly connected to the right side of the screen plate 1, and an auxiliary rebound component is provided on the lower surface of the screen plate 1.

[0015] Please see Figures 1 to 2 The upper surface of the first support 2 is equipped with four rollers 13, and the lower surface of the screen plate 1 is provided with a slide that can be adapted to the rollers 13. The four rollers 13 can rotate synchronously with the shaking of the screen plate 1. Therefore, when the screen plate 1 shakes, the setting of the rollers 13 can significantly reduce the friction generated by the screen plate 1 during the movement. The receiving plate 14 is fixedly connected to the first support 2 at an incline.

[0016] Please see Figures 1 to 2 The left side of the second bracket 3 is fixedly connected with multiple stabilizing connecting plates 15, and the end of the stabilizing connecting plate 15 away from the second bracket 3 can be inserted into the first bracket 2. The right end of the first bracket 2 is threaded with multiple stabilizing bolts 16, one end of which passes through the corresponding stabilizing connecting plate 15. Therefore, the operator can use the stabilizing connecting plate 15 and the stabilizing bolt 16 to fix the first bracket 2 and the second bracket 3 in place; conversely, when it is necessary to disassemble, the operator only needs to remove the stabilizing bolt 16 from the first bracket 2 and then separate the stabilizing connecting plate 15 from the first bracket 2, so that the first bracket 2 and the second bracket 3 can be switched to an independent working state.

[0017] Please see Figures 1 to 2 The driving component includes a drive motor 4 fixedly mounted in the middle of the second bracket 3, with a drive wheel fixedly connected to the shaft at the front end of the drive motor 4. A rotatable auxiliary shaft is mounted on the upper surface of the second bracket 3, with two bearing seats fixedly mounted on the upper surface of the second bracket 3. Each bearing seat contains a suitable bearing. The auxiliary shaft is mounted on these two bearings to allow for flexible rotation. A driven wheel 5 is fixedly connected to the middle of the auxiliary shaft. A drive belt is fitted onto both the driven wheel 5 and the drive wheel. Both the driven wheel 5 and the drive wheel are pulleys. Therefore, when the drive motor 4 starts running, it directly drives the drive wheel to rotate, and the drive wheel then drives the driven wheel 5 to rotate synchronously via the drive belt. An active drive plate 6 is fixedly connected to the rear end of the auxiliary shaft, and the active drive plate 6 is located away from the auxiliary shaft. One end of the auxiliary shaft is rotatably connected to a driven rod 7. The end of the driven rod 7 away from the active drive plate 6 is detachably hinged to the screen plate 1. Two hinge plates are fixedly connected to the middle right side of the screen plate 1. A bolt passes through one side of one of the hinge plates and then through the other hinge plate. A nut is screwed onto one end of the bolt for fastening. The end of the driven rod 7 away from the active drive plate 6 is rotatably connected to the bolt. Therefore, when the driven wheel 5 rotates, it will synchronously drive the auxiliary shaft to rotate. The auxiliary shaft will then drive the active drive plate 6 to rotate. The rotation of the active drive plate 6 will drive the right end of the driven rod 7 to rotate around the auxiliary shaft with the active drive plate 6. Finally, the left end of the driven rod 7 will drive the screen plate 1 to move back and forth.

[0018] Please see Figures 1 to 2 The auxiliary rebound component includes multiple third baffles 11 fixedly connected to the lower surface of the screen plate 1, and two fourth baffles 12 fixedly connected to the left end of the upper surface of the first support 2, and two first baffles 9 fixedly connected to the right end of the upper surface of the first support 2. A spring 18 is fixedly connected to the left side of each first baffle 9, and a second baffle 10 is fixedly connected to the end of the spring 18 away from the first baffle 9. Therefore, when a person needs to use the screen plate 1 on the first support 2 alone, the person can turn the nut on the bolt to separate the nut from the bolt, so that the bolt can be pulled away from the two hinge plates and the driven rod 7. Then the person also needs to turn the stabilizing bolt 16 to pull the stabilizing bolt 16 away from the first support 2 and the stabilizing connecting plate 15. Then the person can separate the first support 2 from the second support 3. Then the person can shake the screen plate 1 by using the handle 8. However, during the shaking of the screen plate 1, the operator can manually pull the screen plate 1 to the right: at this time, the third baffle 11 on the right end of the lower surface of the screen plate 1 will hit the second baffle 10, thereby pushing the second baffle 10 to squeeze the spring 18. When the operator releases the handle 8, the spring 18 releases its elastic potential energy and pushes the second baffle 10 to move to the left. This movement will simultaneously push the screen plate 1 to return to the left. Under the action of inertia, the screen plate 1 continues to move to the left, and the third baffle 11 on the left end of the lower surface of the screen plate 1 will hit the fourth baffle 12, thus completing a manually driven shaking action. In this way, even in outdoor scenarios without power supply, wheat on the screen plate 1 can be screened and impurities removed. Both the first support 2 and the second support 3 are equipped with pulleys at their bottom ends. With the help of the pulleys, the movement of the first support 2 and the second support 3 by personnel is effectively simplified.

[0019] In summary, when using this wheat grain impurity removal and screening device, two modes can be selected: electric drive or manual drive, depending on the actual scenario. If there is a power supply, the electric drive mode should be used first. The operator first inserts the stabilizing connecting plate 15 on the second bracket 3 into the first bracket 2, then inserts the stabilizing bolt 16 through the stabilizing connecting plate 15 and threadedly connects it to the first bracket 2, fixing the first bracket 2 and the second bracket 3 as one unit. Then, the end of the driven drive rod 7 away from the active drive plate 6 is hinged to the two hinge plates on the right side of the screen plate 1 by bolts. Tightening the nut at one end of the bolt completes the fixation. The drive motor 4 in the middle of the second bracket 3 is started, and the drive motor 4 drives the front rotating shaft. The active wheel rotates, and the active wheel drives the driven wheel 5 to rotate synchronously through the drive belt (the driven wheel 5 is fixed to the middle of the auxiliary shaft supported by the bearing seat on the upper surface of the second bracket 3). The auxiliary shaft rotates with the driven wheel 5, which drives the active drive plate 6 at the rear end to rotate. The active drive plate 6 pulls the screen plate 1 along the four rollers 13 at the top of the first bracket 2 (which are adapted to the slide rail on the lower surface of the screen plate 1) to swing back and forth. During this process, the wheat material on the surface of the screen plate 1 is separated by the shaking. Large particles of impurities are trapped on the screen plate 1, while wheat that meets the screening specifications falls directly below the screen plate 1 and is tilted and fixed on the receiving plate 14 of the first bracket 2. It slides down the inclined surface of the receiving plate 14 and is collected. If the location is outdoors without power supply, the manual drive mode can be switched: First, unscrew the nuts on the bolts on the hinge plate, pull the bolts out of the hinge plate and driven rod 7, and disconnect the driven rod 7 from the screen plate 1; then unscrew the stabilizing bolt 16, separate the stabilizing connecting plate 15 from the first bracket 2, making the first bracket 2 independent of the second bracket 3. The operator can then manually shake the screen plate 1 using the handle 8 on the right side of the screen plate 1: when pulling the screen plate 1 to the right, the third baffle 11 on its lower surface will strike the second baffle 10 on the left side of the first baffle 9 on the upper surface of the first bracket 2, pushing... When the second baffle 10 is pressed and the spring 18 is released, the spring 18 releases its elastic potential energy to push the second baffle 10 back to its original position, causing the screen plate 1 to move to the left. The third baffle 11 on the left end of the lower surface of the screen plate 1 strikes the fourth baffle 12 on the left end of the upper surface of the first support 2, completing one reciprocating swing. By continuously operating the handle 8, the screen plate 1 can be stably shaken by pressing the spring 18, thus achieving the effect of wheat impurity removal and screening. In addition, the pulleys installed at the bottom of the first support 2 and the second support 3 can greatly simplify the movement of the device between different work locations and improve the flexibility of use.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
