DETAILED DESCRIPTION
[0016] The technical solutions in the embodiments of the utility model will be apparently and completely described in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.
[0017] Please refer to Figs. 1-3This utility model provides a technical solution: including a dust collection hood 2 and a water collection tank 3 installed above a straw crusher 1. A connecting hose 4 is fixed to the upper end of the dust collection hood 2, and the end of the connecting hose 4 is inserted into the water collection tank 3. An exhaust fan 21 is installed inside the dust collection hood 2. A circular frame 5 is fixed to the bottom periphery of the dust collection hood 2. An annular track 51 is fixed to the middle position of the lower end of the circular frame 5. A track plate 52 is slidably connected to the annular track 51. A positioning component 6 is provided between the track plate 52 and the annular track 51. A set of windbreak curtains 53 is fixed to the bottom of the track plate 52. A connecting rod 7 is fixed between the dust collection hood 2 and the circular frame 5. Mounting columns 22 are fixed between the four corners of the bottom of the dust collection hood 2 and the straw crusher 1. A feed hopper 11 is fixed to the outside of the straw crusher 1, and the bottom of the feed hopper 11 is located at the opening of the straw crusher 1. The windbreak curtains 53 are made of transparent rubber material, and the length of the windbreak curtains 53 is greater than the length between the straw crusher 1 and the dust collection hood 2. The edges of adjacent windbreak curtains 53 overlap.
[0018] The positioning component 6 includes a positioning hole 61 and a positioning rod 62. The positioning hole 61 is opened at the bottom of the circular frame 5 and is equidistantly distributed around the periphery of the annular track 51. The positioning rod 62 is installed on the upper end of the track plate 52 and is aligned with the positioning hole 61. The upper end of the positioning rod 62 is inserted into one of the positioning holes 61. A telescopic groove 63 is opened in the track plate 52 at a position corresponding to the positioning rod 62. The bottom of the positioning rod 62 is slidably connected to the telescopic groove 63. A push-out spring 64 is fixed between the bottom of the positioning rod 62 and the bottom of the telescopic groove 63. An extension rod 65 is fixed at the middle position of the bottom of the positioning rod 62. The bottom of the extension rod 65 extends out of the telescopic groove 63 and is fixed with a pull ring 66.
[0019] Working principle: First, connect the entire device to an external power source. During straw feeding and crushing, the exhaust fan 21 absorbs air, and all dust is discharged into the collection tank 3 through the connecting hose 4, reducing pollution to the working environment. If it is windy during outdoor operation, the rolled-up windbreak curtain 53 can be unfolded to block the gap between the dust suction hood 2 and the straw crusher 1, preventing airflow through the gap and thus preventing dust from being scattered by the wind, ensuring effective dust collection. Secondly, because the track plate 52 can be used in a circular... The slide on the track 51, thereby moving the windproof curtain 53. It can provide wind protection at different positions around the straw crusher 1, which is suitable for different wind conditions. During this process, the pull ring 66 can be pulled. When the ejector spring 64 is compressed, the positioning rod 62 moves downward, so that its upper end is pulled out from the positioning hole 61, allowing the track plate 52 to slide freely. Conversely, when the ejector spring 64 is reset and ejected, the upper end of the positioning rod 62 can be reinserted into the positioning hole 61 to fix the track plate 52.
