Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a material guiding component of a multifunctional silage harvester. Background Technology

[0002] Harvesting is a crucial step in silage production, and the feed conveyor plays a vital role in material transport within the harvester. Existing silage harvesters typically use feed conveyors to transport the chopped crop to subsequent processing units, but their designs are mostly single-function structures, making it difficult to meet the adaptability requirements of various crops.

[0003] In actual operations, different types of silage crops have different physical characteristics, such as significant differences in stalk thickness, moisture content, and density. This necessitates that the material guiding components have a certain degree of adjustability to ensure efficient and uniform material transport. However, the design of existing material guiding components often lacks flexibility, easily leading to poor transport or blockages when dealing with different crops, thus affecting overall operational efficiency.

[0004] Furthermore, to improve the quality of silage, it is necessary to minimize the breakage rate of the material during transportation. Current feed guiding components do not adequately consider the protection of the material in their structural design, easily leading to problems such as stem and leaf separation or excessive crushing. This not only reduces the nutritional value of the feed but may also increase the difficulty of subsequent processing. Therefore, existing technologies still have room for improvement in terms of adaptability and protective properties. Utility Model Content

[0026] This utility model provides a material guiding component for a multifunctional silage harvester, the specific implementation of which is combined with... Figures 1 to 2 Please provide a detailed explanation. For example... Figure 1As shown, the material guiding assembly includes a support frame 1, a conveying mechanism, and an adjusting mechanism. The support frame 1 is a rectangular frame structure with a mounting plate on its top, which is fixedly connected to the harvester body by bolts. Slide rails are provided on both sides of the bottom of the support frame 1, and adjustable side plates 7 are slidably connected to the slide rails. Multiple evenly distributed through holes are provided on the adjustable side plates 7, and guide posts are inserted into the through holes. One end of the guide post is fixedly connected to the support frame 1, and the other end is locked with a nut. A wear-resistant layer made of polymer material is adhered to the inner surface of the adjustable side plates 7 to reduce friction between the material and the side plates.

[0027] The conveying mechanism is located inside the support frame 1 and includes a drive roller 3, a driven roller 4, and a conveyor belt 2 wound between them. The drive roller 3 is fixed to one end of the support frame 1 by a bearing seat, and one end of the drive roller 3 extends outside the support frame 1 and is connected to the output shaft of the drive motor 8 via a coupling. The drive motor 8 is fixed to the outside of the support frame 1 by a motor bracket, which is equipped with shock-absorbing pads made of rubber. The driven roller 4 is mounted to the other end of the support frame 1 by a tensioning device, which includes a screw and an adjusting handwheel. The screw passes through the support frame 1 and is threadedly connected to the bearing seat of the driven roller 4. By rotating the adjusting handwheel, the position of the driven roller 4 can be adjusted to achieve tensioning of the conveyor belt 2.

[0028] The surface of the conveyor belt 2 is provided with multiple sets of raised structures, each set of raised structures being evenly arranged along the width direction of the conveyor belt 2. The height of the raised structures is 1 / 3 to 1 / 2 of the thickness of the conveyor belt 2, and the spacing between adjacent raised structures can be adjusted according to the material characteristics. Figure 2 As shown, elastic pressure strips 5 are fixed to the inner walls of the support frames 1 on both sides of the conveyor belt 2. The elastic pressure strips 5 are made of flexible material, with their lower ends maintaining a certain gap from the surface of the conveyor belt 2. The upper ends of the elastic pressure strips 5 are fixed to mounting grooves on the inner wall of the support frame 1 by clips. Spring plates are installed in the mounting grooves, with one end of the spring plate contacting the elastic pressure strip 5 and the other end contacting the bottom of the mounting groove. Through the elastic force of the spring plates, the elastic pressure strips 5 can automatically adjust the gap with the surface of the conveyor belt 2 according to the material thickness.

[0029] The adjusting mechanism includes two sets of elastic pressure strips 5 and a set of partition plates 6. The partition plates 6 are vertically positioned in the middle of the conveyor belt 2. Both ends of the partition plates 6 are slidably connected to the inner wall of the support frame 1 via grooves, with positioning pins installed in the grooves to fix the position of the partition plates 6. The two sides of the partition plates 6 have rounded chamfers with a radius of curvature of 5mm to 10mm to reduce collision damage between materials and the partition plates 6. The surface of the partition plates 6 is coated with an anti-stick coating made of polytetrafluoroethylene (PTFE) to prevent material adhesion.

[0030] A dust collection box 9 is installed at the bottom of the support frame 1, and the dust collection box 9 is connected to the support frame 1 by a snap-fit. A dust inlet is provided at the top of the dust collection box 9, and a filter screen is installed at the dust inlet to collect debris and dust generated during the conveying process. Cleaning devices 10 are respectively installed at both ends of the conveyor belt 2. The cleaning device 10 includes a scraper and a brush. The scraper is fixed to the inner wall of the support frame 1 by bolts, and its lower end contacts the surface of the conveyor belt 2. The brush is mounted on one side of the scraper via a rotating shaft. One end of the rotating shaft is connected to the scraper bearing, and the other end is connected to the drive roller 3 via a belt.

[0031] In actual operation, the drive motor 8 drives the active roller 3 to rotate, and the active roller 3 drives the driven roller 4 to operate synchronously through the conveyor belt 2, thereby realizing the material conveying. After the material enters from the guide channel, the raised structure on the surface of the conveyor belt 2 increases the friction, ensuring stable material conveying. The elastic pressure strip 5 applies appropriate clamping force to the material, reducing the jumping and deviation of the material during the conveying process. The separator 6 divides the conveyor belt 2 into multiple areas to avoid material accumulation and blockage. The debris and dust generated during the conveying process enter the dust collection box 9 through the filter screen, and the scraper and brush of the cleaning device 10 clean the surface of the conveyor belt 2, keeping the guide assembly clean.

[0032] This invention achieves efficient conveying of various silage crops through the above-described structural design, while significantly improving the adaptability and protective properties of the material guiding assembly. The adjustable side plate 7 allows for flexible adjustment of the material guiding channel size according to the material width. The combined use of the elastic pressure strip 5 and the partition plate 6 effectively reduces material breakage and blockage. The dust collection box 9 and the cleaning device 10 extend the service life of the material guiding assembly. To better enable those skilled in the art to fully understand and implement this invention, the specific implementation principle is further explained below with reference to a specific application scenario.

[0033] In silage harvesting operations, the material guiding assembly is first fixedly connected to the harvester body via the mounting plate on top of the support frame 1. At this point, depending on the width characteristics of the silage crop to be processed, the operator can adjust the position of the adjustable side plate 7 via the slide rail. Specifically, loosening the nut on the guide column allows the adjustable side plate 7 to slide along the slide rail to the appropriate position, after which the nut is tightened again to ensure that the width of the material guiding channel matches the material size. The wear-resistant layer on the inner surface of the adjustable side plate 7 effectively reduces frictional wear when the material contacts it, thereby extending the service life of the side plate.

[0034] Then, the drive motor 8 is started, which drives the drive roller 3 to rotate via a coupling. The drive roller 3 further drives the conveyor belt 2 to rotate, while the driven roller 4 maintains appropriate tension on the conveyor belt 2 through a tensioning device. During the conveying process, the raised structures on the surface of the conveyor belt 2 increase friction to enhance the material gripping ability. At the same time, the spacing between adjacent raised structures can be adjusted according to the physical characteristics of different crops (such as stem thickness and moisture content) to ensure that the material can move stably with the conveyor belt without slipping.

[0035] Once the material enters the guide channel, the elastic pressure strip 5 begins to function. Because the elastic pressure strip 5 is connected to the inner wall of the support frame 1 via spring sheets, its lower end automatically adjusts the gap with the surface of the conveyor belt 2 according to the material thickness. This design ensures smooth material conveying while preventing material damage due to excessive pressure. Furthermore, the separator plate 6 divides the conveyor belt 2 into multiple zones, effectively preventing material accumulation or blockage. The rounded chamfers on both sides of the separator plate 6 and the anti-stick coating further reduce collision damage and adhesion problems between the material and the separator plate.

[0036] During material conveying, some debris and dust may fall off and remain suspended in the air. At this time, the dust inlet at the top of the dust collection box 9 collects this debris and dust through a filter screen, thereby reducing environmental pollution and keeping the working environment of the material guiding components clean. Simultaneously, the scraper and brush in the cleaning device 10 work together to clean the surface of the conveyor belt 2. The scraper directly contacts the surface of the conveyor belt 2 to remove stubborn deposits, while the brush is connected to the drive roller 3 via a rotating shaft, continuously cleaning during the operation of the conveyor belt 2 to ensure that the surface of the conveyor belt 2 remains clean at all times.

[0037] The above steps enable the efficient operation of the material guiding assembly in the conveying process of various silage crops. For example, when handling crops with thicker and denser stalks, the spacing of the raised structures on the surface of the conveyor belt 2 and the clamping force of the elastic pressure strip 5 can be adjusted to ensure smooth material conveying. For crops with high moisture content and easy adhesion, the anti-stick coating and rounded chamfer design of the separator plate 6 can significantly reduce the risk of material adhesion and collision damage.

[0038] In summary, through the synergistic effect of the adjustable side plate 7, elastic pressure strip 5, partition plate 6, and cleaning device 10, this utility model can not only flexibly adapt to the physical characteristics of different types of silage crops, but also effectively reduce material breakage and blockage, providing a reliable technical guarantee for the high-quality production of silage.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
