Abstract
Description
Technical Field
[0001] This utility model relates to the field of wheat seed technology, and specifically to a wheat seed impurity removal device. Background Technology
[0002] In the wheat seed processing industry, impurity removal devices are crucial equipment for ensuring seed quality. They remove impurities from seeds through techniques such as screening and air separation, ensuring the purity of the wheat seeds. However, most wheat seed impurity removal devices currently on the market have significant defects in the unloading process.
[0003] The aforementioned problems exist: Traditional impurity removal devices typically collect the removed wheat seeds in a bottom storage silo. Unloading relies on manual operation; workers must manually open the silo door and use tools to push or shovel the seeds out. This manual unloading method has many drawbacks: Firstly, wheat seeds are heavy and have poor flowability, making manual pushing time-consuming and labor-intensive, requiring multiple people and incurring high labor intensity. Workers are prone to fatigue after prolonged work, leading to low operational efficiency and severely impacting production progress. Secondly, manual unloading makes it difficult to ensure uniformity and thoroughness, often leaving seeds in corners or at the bottom of the storage silo. This not only wastes materials but also requires additional cleaning, increasing labor and time costs. Therefore, a wheat seed impurity removal device is proposed to solve these problems. Utility Model Content
[0004] The purpose of this invention is to provide a device for removing impurities from wheat seeds, so as to solve the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0006] A wheat seed impurity removal device includes an inclined screening cylinder and a support frame. The outer wall of the support frame is provided with a collection component for collecting and unloading wheat seeds. The collection component includes a fixed frame, the outer wall of which is fixedly connected to the inner wall of the support frame. A pusher plate is slidably connected inside the fixed frame. A connecting frame is fixedly connected to one side of the pusher plate. A baffle is fixedly connected to one side of the connecting frame. A force-bearing block is fixedly connected to the outer wall of the baffle. A cylinder is fixedly connected to the outer wall of the fixed frame. The output end of the cylinder is fixedly connected to one side of the force-bearing block. A screening component is provided at the top of the support frame, and a baffle component is provided on the outer wall of the support frame.
[0007] The above technical solution involves the coordinated operation of a fixed frame, connecting frame, baffle, force-bearing block, and cylinder. In the collection component, the cylinder pushes the force-bearing block, baffle, connecting frame, and pusher plate to slide within the fixed frame, automatically pushing out the collected wheat seeds for unloading. This eliminates the need for manual operation, reduces labor intensity, improves unloading efficiency, and ensures the continuity of the impurity removal work.
[0008] A further improvement of the present invention is that: a sliding groove is provided inside the fixed frame, and a slider is slidably connected inside the sliding groove; the outer wall of the slider is fixedly connected to one side of the baffle.
[0009] The above technical solution involves the cooperation of a chute, a slider, and a baffle. The chute and slider in the fixed frame provide stable guidance for the sliding of the baffle and the pusher plate. During the cylinder push, the baffle is effectively prevented from tilting or shifting, ensuring that the pusher plate pushes the wheat seeds smoothly, ensuring a smooth unloading process, and avoiding the impact of jamming on work efficiency.
[0010] A further improvement of the present invention is that the screening component includes a mounting base, the outer wall of the mounting base is fixedly connected to the top of the support frame, and a motor is fixedly installed inside the mounting base.
[0011] The above technical solution, through the cooperation of the mounting base and the motor, and the cooperation of the sliding groove and the slider in the fixed frame, provides stable guidance for the sliding of the baffle and the pusher plate. During the cylinder push, it effectively prevents the baffle from tilting or deviating, ensures that the pusher plate pushes the wheat seeds smoothly, ensures a smooth unloading process, and avoids affecting work efficiency due to jamming.
[0012] A further improvement of this utility model is that: a fixed plate is fixedly connected to the output end of the motor, a feeding trough is provided inside the fixed plate, and one side of the fixed plate is fixedly connected to one end of the inclined screening cylinder.
[0013] The above technical solution involves the coordinated use of a fixed plate, a feeding trough, and an inclined screening cylinder. The fixed plate at the motor output end feeds wheat seeds precisely through the feeding trough. Simultaneously, the fixed plate is fixedly connected to the inclined screening cylinder, directly transmitting the motor power to the screening cylinder. This ensures stable rotation of the screening cylinder, allowing the seeds to tumble and be screened thoroughly within the cylinder, thereby improving the accuracy and efficiency of impurity removal.
[0014] A further improvement of this utility model is that: a limiting block is fixedly connected to the top of the support frame, a rotating rod is rotatably connected inside the limiting block, and the outer wall of the rotating rod is fixedly connected to the outer wall of the inclined screening cylinder.
[0015] The above technical solution involves the coordinated use of a limiting block, a rotating rod, and an inclined screening cylinder. The limiting block provides stable support for the rotating rod, ensuring the inclined screening cylinder remains stable during rotation and reducing swaying. The rotating rod is fixedly connected to the inclined screening cylinder, ensuring smooth rotation of the screening cylinder, guaranteeing the stability of wheat seeds during screening within the cylinder, and improving the impurity removal effect.
[0016] A further improvement of the present invention is that the material blocking assembly includes a fixing block, one side of the fixing block is fixedly connected to one side of the support frame, a screw is threadedly connected to the inside of the fixing block, a material blocking plate is fixedly connected to the outer wall of the screw, and a rotating block is fixedly connected to one end of the screw.
[0017] The above technical solution involves the cooperation of a fixed block, a screw, a baffle plate, and a rotating block. Rotating the rotating block at one end of the screw causes the screw and the fixed block to move up and down via a threaded transmission. The position of the baffle plate can be flexibly adjusted according to actual needs to control the flow range of wheat seeds, effectively preventing seed spillage, and adapting to the impurity removal requirements of different working scenarios.
[0018] A further improvement of this utility model is that: a guide block is fixedly connected to the bottom of the support frame, the bottom of the guide block is located directly above the collecting component, and several material drop troughs are opened inside the inclined screening cylinder.
[0019] The above technical solution involves the coordinated use of guide blocks and drop troughs. The guide blocks at the bottom of the support frame accurately guide the screened wheat seeds to the collection components, preventing the seeds from scattering. The multiple drop troughs inside the inclined screening cylinder allow the seeds to fall evenly during the screening process. Together with the guide blocks, this achieves efficient material transport, ensures a smooth impurity removal process, and improves overall work efficiency.
[0020] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared with the prior art is that it can automatically push out the collected wheat seeds for unloading, eliminating the need for manual operation, reducing labor intensity, and improving unloading efficiency.
[0021] This utility model provides a wheat seed impurity removal device. By setting up a fixed frame, connecting frame, baffle, force block and cylinder in cooperation, in the collection component, the cylinder pushes the force block, baffle, connecting frame and push plate to slide in the fixed frame, which can automatically push out the collected wheat seeds for unloading. No manual operation is required, reducing labor intensity, improving unloading efficiency and ensuring the continuity of impurity removal work.
[0022] This utility model provides a wheat seed impurity removal device. By setting up a fixed plate, a feeding trough and an inclined screening cylinder, the fixed plate at the motor output end achieves precise feeding of wheat seeds through the feeding trough. At the same time, the fixed plate is fixedly connected to the inclined screening cylinder, directly transmitting the motor power to the screening cylinder, ensuring stable rotation of the screening cylinder, and allowing the seeds to tumble and screen fully inside the cylinder, thereby improving the impurity removal accuracy and efficiency.
[0023] This utility model provides a wheat seed impurity removal device. By setting up a fixed block, a screw, a baffle plate and a rotating block in cooperation, rotating the rotating block at one end of the screw, the screw and the fixed block are driven by a thread, which drives the baffle plate to move up and down. The position of the baffle plate can be flexibly adjusted according to actual needs to control the flow range of wheat seeds, effectively prevent seeds from overflowing, and adapt to the impurity removal needs in different working scenarios.

[0029] The present invention will be further described in detail below with reference to embodiments:
[0030] Example 1
[0031] like Figure 1-4 As shown, this utility model provides a wheat seed impurity removal device, including an inclined screening cylinder 1 and a support frame 2. The outer wall of the support frame 2 is provided with a collection component for collecting and unloading wheat seeds. The collection component includes a fixed frame 3, the outer wall of the fixed frame 3 and the inner wall of the support frame 2 are fixedly connected. A pusher plate 4 is slidably connected inside the fixed frame 3. A connecting frame 5 is fixedly connected to one side of the pusher plate 4. A baffle 6 is fixedly connected to one side of the connecting frame 5. A force-bearing block 7 is fixedly connected to the outer wall of the baffle 6. A cylinder 8 is fixedly connected to the outer wall of the fixed frame 3. The output end of the cylinder 8 is fixedly connected to one side of the force-bearing block 7. A screening component is provided on the top of the support frame 2. A baffle component is provided on the outer wall of the support frame 2. A sliding groove 9 is opened inside the fixed frame 3. A slider 10 is slidably connected inside the sliding groove 9. The outer wall of the slider 10 is fixedly connected to one side of the baffle 6.
[0032] In this embodiment, by setting up a fixed frame 3, a connecting frame 5, a baffle 6, a force-bearing block 7, and a cylinder 8 in cooperation, the cylinder 8 pushes the force-bearing block 7, the baffle 6, the connecting frame 5, and the pusher plate 4 to slide within the fixed frame 3, which can automatically push out the collected wheat seeds for unloading without manual operation, reducing labor intensity, improving unloading efficiency, and ensuring the continuity of the impurity removal work. By setting up a sliding groove 9, a slider 10, and a baffle 6 in cooperation, the sliding groove 9 and the slider 10 in the fixed frame 3 cooperate to provide stable guidance for the sliding of the baffle 6 and the pusher plate 4. During the pushing process of the cylinder 8, it effectively prevents the baffle 6 from tilting or deviating, ensuring that the pusher plate 4 pushes the wheat seeds smoothly, ensuring a smooth unloading process, and avoiding the impact of jamming on work efficiency.
[0033] Example 2
[0034] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the screening assembly includes a mounting base 11, the outer wall of the mounting base 11 is fixedly connected to the top of the support frame 2, a motor 12 is fixedly installed inside the mounting base 11, a fixed plate 13 is fixedly connected to the output end of the motor 12, a feeding trough 14 is opened inside the fixed plate 13, one side of the fixed plate 13 is fixedly connected to one end of the inclined screening cylinder 1, a limiting block 15 is fixedly connected to the top of the support frame 2, and a rotating mechanism is rotatably connected inside the limiting block 15. The outer wall of the rotating rod 16 is fixedly connected to the outer wall of the inclined screening cylinder 1. The baffle assembly includes a fixed block 17. One side of the fixed block 17 is fixedly connected to one side of the support frame 2. The fixed block 17 is internally threaded with a screw 18. The outer wall of the screw 18 is fixedly connected with a baffle plate 19. One end of the screw 18 is fixedly connected with a rotating block 20. The bottom of the support frame 2 is fixedly connected with a guide block 21. The bottom of the guide block 21 is located directly above the collection assembly. Several material drop troughs 22 are opened inside the inclined screening cylinder 1.
[0035] In this embodiment, by setting the mounting base 11 and the motor 12 in cooperation, the sliding groove 9 in the fixed frame 3 cooperates with the slider 10 to provide stable guidance for the sliding of the baffle 6 and the pusher plate 4. During the pushing process of the cylinder 8, it effectively prevents the baffle 6 from tilting or deviating, ensuring that the pusher plate 4 pushes the wheat seeds smoothly, ensuring a smooth unloading process, and avoiding the impact of jamming on work efficiency. By setting the fixed plate 13, the feeding trough 14 and the inclined screening cylinder 1 in cooperation, the fixed plate 13 at the output end of the motor 12 achieves precise feeding of wheat seeds through the feeding trough 14. At the same time, the fixed plate 13 is fixedly connected to the inclined screening cylinder 1, directly transmitting the power of the motor 12 to the screening cylinder, ensuring the stable rotation of the screening cylinder, so that the seeds can be fully tumbled and screened in the cylinder, improving the impurity removal accuracy and efficiency. By setting the limit block 15, the rotating rod 16 and the inclined screening cylinder 1 in cooperation, the limit block 15 provides stable support for the rotating rod 16, so that the inclined screening cylinder 1 remains stable during rotation. To reduce shaking, the rotating rod 16 is fixedly connected to the inclined screening cylinder 1, ensuring smooth rotation of the screening cylinder and guaranteeing the stability of wheat seeds during screening, thus improving the impurity removal effect. Through the cooperation of the fixed block 17, screw 18, baffle plate 19, and rotating block 20, rotating the rotating block 20 at one end of the screw 18 causes the screw 18 and fixed block 17 to be threaded together, driving the baffle plate 19 to move up and down. The position of the baffle plate 19 can be flexibly adjusted according to actual needs to control the flow range of wheat seeds, effectively preventing seed spillage and adapting to impurity removal requirements in different working scenarios. Through the cooperation of the guide block 21 and the drop chute 22, the guide block 21 at the bottom of the support frame 2 accurately guides the screened wheat seeds to the collection component, preventing seed scattering. Multiple drop chute 22 inside the inclined screening cylinder 1 ensure that seeds fall evenly during screening, and together with the guide block 21, achieves efficient material transfer, ensuring a smooth impurity removal process and improving overall work efficiency.
[0036] The working principle of this wheat seed impurity removal device will be explained in detail below.
[0037] like Figure 1-4 As shown, the motor 12 inside the mounting base 11 starts, driving the fixed disk 13 to rotate. The fixed disk 13 is connected to the inclined screening cylinder 1, thereby driving the inclined screening cylinder 1 to rotate around the rotating rod 16. The inclined screening cylinder 1 rotates stably under the support of the limit block 15. The wheat seeds inside the cylinder tumble continuously as the cylinder rotates. Impurities are separated out through the feeding trough 14 on the cylinder wall, and qualified wheat seeds continue to be screened inside the cylinder. The feeding trough 14 on the fixed disk 13 controls the wheat seeds to enter the screening cylinder evenly, ensuring the continuity and stability of the screening process.
[0038] After screening, the wheat seeds are guided into the fixed frame 3 by the guide block 21 at the bottom of the support frame 2. At this time, the cylinder 8 extends and pushes the force block 7, baffle 6, connecting frame 5 and push plate 4 to slide in the fixed frame 3. Under the guidance of the slide groove 9 and the slider 10, the push plate 4 smoothly pushes out the wheat seeds collected in the fixed frame 3 for unloading. After unloading, the cylinder 8 retracts and the push plate 4 resets, ready for the next collection and unloading.
[0039] According to actual needs, the rotating block 20 at one end of the screw 18 is rotated, and the screw 18 and the fixed block 17 are driven by a thread, which drives the baffle plate 19 to move up and down. By adjusting the position of the baffle plate 19, the flow range of wheat seeds can be controlled to prevent the seeds from overflowing during screening and transmission, and to ensure that the impurity removal work is carried out in an orderly space.
[0040] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
