Description

Technical Field

[0001] This utility model relates to the field of straw cleaning technology, and in particular to straw cleaning equipment. Background Technology

[0002] With the continuous development of agricultural production, straw, as a by-product of crop harvesting, has received increasing attention. Traditionally, straw was considered waste and was often directly burned or piled up, causing environmental pollution and resource waste. However, with the increasing awareness of resource recycling and environmental protection, straw has gradually been given higher utilization value. The development of modern agricultural mechanization has promoted the innovation of straw cleaning equipment. Especially in the application of straw crushing as cattle and sheep feed, the role of cleaning equipment has become particularly important. Through advanced screening technology, impurities such as gravel and dust in straw can be effectively separated, making straw a high-quality feed raw material after processing. This not only improves the quality of feed and enhances breeding efficiency, but also promotes the resource utilization of straw and reduces environmental pollution.

[0003] Existing straw cleaning equipment typically operates based on the principle of vibrating screening. Its basic structure includes a screen, a vibration source, and a driving device. The screen is used to classify and screen the straw.

[0004] A significant problem faced by existing straw cleaning equipment in practical applications is the difficulty in effectively classifying materials inside the screen, especially when materials accumulate. This often affects screen cleaning and smooth material passage. Due to the differences in physical properties between straw and impurities such as gravel and dust, the vibration effect of traditional screening equipment often fails to thoroughly classify the materials, resulting in larger particles such as gravel and smaller particles such as dust remaining on the screen, affecting the screening effect. Furthermore, once a large amount of material accumulates on the screen, the discharge port is easily blocked, preventing the material from being discharged smoothly, leading to decreased equipment efficiency and increased cleaning costs. Therefore, straw cleaning equipment is proposed to solve these problems. Utility Model Content

[0023] 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.

[0024] Reference Figure 1 and Figure 2 An embodiment of the present invention provides: the straw cleaning equipment includes a support frame 1, a connecting plate 7 is fixedly connected inside the support frame 1, a spring plate 13 is fixedly connected to the bottom of the connecting plate 7, and a screening component is fixedly connected to the side wall of the spring plate 13.

[0025] The screening assembly, used for cleaning straw, consists of a primary screen 10 and a secondary screen 11. The sidewalls of the primary screen 10 and the secondary screen 11 are fixedly connected to the sidewalls of the spring plates 13. A double-headed motor 8 is fixedly connected to the top of the primary screen 10, and its output is connected to the secondary screen 11 via a connecting rod 12, driving the screens to vibrate and screen, separating straw impurities. A control cabinet 3 is installed on the top of the support frame 1, responsible for controlling the operation of the motor and other drive devices. A crushing chamber 2 is fixedly connected to the top of the support frame 1, which processes the input straw material. After crushing, the material is output through a hopper 6. A feeding hopper 5 is connected to the top of the crushing chamber 2 to feed the straw material into it. Both the primary screen 10 and the secondary screen 11 are equipped with pushing components, which consist of push plates, telescopic rods, etc. These components are responsible for timely feeding of the screened straw, ensuring the continuity and efficiency of the screening process. By precisely controlling the movement of the pushing components, straw impurities can be effectively removed, improving the screening effect.

[0026] Specifically, when using the straw cleaning equipment, the straw to be cleaned is first evenly fed into the crushing chamber 2 through the feeding hopper 5. After the crushing chamber 2 performs preliminary processing on the straw, it is effectively dispersed and discharged through the collection frame 4 to the primary screen 10. Next, the dual-head motor 8 is started. The output end of the dual-head motor 8 drives the mechanical parts to rotate and move through the connecting rod 12, further driving the secondary screen 11 to vibrate. Through the movement of the connecting rod 12, the secondary screen 11 produces appropriate shaking. The sliding of the secondary screen 11 causes the spring plate 13 to swing, and the swing of the spring plate 13 in turn causes the primary screen 10 to vibrate, thus forming the primary screen 10. The linkage vibration effect between screen 10 and secondary screen 11 enables effective screening of materials such as straw, stones, and dust. During screening, larger stones are effectively blocked by the primary screen 10, preventing them from falling through the screen and ensuring efficient material separation. At the same time, straw smoothly enters the secondary screen 11 through the primary screen 10. With the continuous vibration of the secondary screen 11, it can not only effectively remove larger particles of impurities, but also further screen the dust and smaller particles inside the straw. Through this multi-level vibration screening, impurities and dust in the straw are greatly reduced, achieving the purpose of cleaning.

[0027] Reference Figure 3 and Figure 4The pushing component includes push plate 16 and push plate 2 17, which are slidably connected inside the secondary screen 11 and the primary screen 10, respectively. Push plate 16 is connected to the secondary screen 11 via the output end of electric telescopic rod 2 15, and push plate 2 17 is connected to the primary screen 10 via the output end of electric telescopic rod 1 9, ensuring that the straw inside the two screens can be effectively pushed out of the screens. Electric telescopic rod 1 9 and electric telescopic rod 2 15 are controlled by electric drive to move the push plates, thereby completing the straw cleaning and unloading operation. A sliding door 2 18 is slidably connected inside the primary screen 10, and a sliding door 1 14 is slidably connected inside the secondary screen 11. The design of the sliding doors facilitates cleaning. The screen is opened quickly during the selection process to clean the material and ensure smooth operation of the equipment. A collection frame 4 is slidably connected inside the support frame 1. The collection frame 4 is used to collect the cleaned straw. A limit rod 19 is fixedly connected to the side wall of the support frame 1. The limit rod 19 ensures that the collection frame 4 remains stable when sliding and prevents displacement. A handle 20 is fixedly connected to the outer wall of the collection frame 4, which makes it convenient for operators to pull the collection frame 4 to transfer materials. A support column 21 is fixedly connected to the bottom of the collection frame 4. The bottom of the support column 21 is equipped with wheels 22. The wheels 22 provide good mobility and facilitate the sliding and transportation of the collection frame 4 between different positions, ensuring that the straw can be easily collected and processed.

[0028] Specifically, after the screening and cleaning process is completed, the straw inside the secondary screen 11 needs to be cleaned and removed in a timely manner. At this time, the operator first opens the secondary screen 11 by pulling up the sliding door 14 to provide sufficient space for straw cleaning. Then, by activating the output end of the electric telescopic rod 15, the pusher plate 16 is pushed to orderly push the straw accumulated in the screen out of the interior of the secondary screen 11. After being pushed, the straw is smoothly delivered to the collection frame 4, ensuring that the screened material is effectively processed. In this process, the movement of the collection frame 4 is also crucial. To facilitate the collection and transportation of straw, the operator pulls the handle 20, using its... The sliding of the collection frame 4 causes the supporting column 21 and wheel 22 below to slide as well. This design not only simplifies the operation process, but also ensures that the straw can be smoothly discharged from the screening equipment and transported to the designated location, completing the first step of the cleaning operation. At the same time, in order to ensure that the screening equipment can operate efficiently and avoid blockage, the push plate 2 17 is also pushed by the output end of the electric telescopic rod 1 9. When the push plate 2 17 pushes against the primary screen 10, it opens the sliding door 2 18 and successfully cleans out the gravel in the primary screen 10, creating a cleaner working environment for the next screening operation.

[0029] Working Principle: When using the straw cleaning equipment, the straw to be cleaned is first placed into the crushing chamber 2 through the feeding hopper 5. After being processed by the crushing chamber 2, it is discharged into the primary screen 10 through the collection frame 4. Then, the double-headed motor 8 is started, and the output end of the double-headed motor 8 drives the connecting rod 12 to rotate. The movement of the connecting rod 12 causes the secondary screen 11 to shake. At the same time, the sliding of the secondary screen 11 causes the spring plate 13 to swing, and the swing of the spring plate 13 causes the primary screen 10 to shake. Through the linkage of the above structure, the secondary screen 11 and the primary screen 10 are vibrated, thereby achieving the purpose of screening the straw, stones and dust inside the primary screen 10 and the secondary screen 11. After the straw is screened and cleaned, larger stones will be blocked by the primary screen 10, and the straw will fall through the primary screen 10 into the secondary screen. On screen 11, the dust inside the straw is vibrated and screened by the vibration of the secondary screen 11. After the screening and cleaning is completed, the straw that has been cleaned inside the secondary screen 11 needs to be taken out. By pulling up the sliding door 14, the secondary screen 11 is opened. Then, by activating the output end of the electric telescopic rod 15, the push plate 16 is pushed to push the straw out of the secondary screen 11. The straw is then pushed into the collection frame 4. Next, by pulling the handle 20, the collection frame 4 is pulled. The movement of the collection frame 4 causes the support column 21 and the wheel 22 below to slide, thereby achieving the purpose of unloading the cleaned straw and transporting it to other locations. The push plate 17 is also pushed by the output end of the electric telescopic rod 9. At the same time, the sliding door 18 is opened to clean the gravel inside the primary screen 10, which is convenient for the next screening.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
