[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1

[0027] like Figures 1 to 5 As shown, this embodiment proposes a dual-shaft forage crushing device, including a machine body 1, a crushing device 2 disposed on the rear side of the machine body 1, a feed inlet 3 opened on the top of the machine body 1, a feeding plate 4 fixedly connected to the inner side wall of the machine body 1, a discharge outlet 6 disposed on the rear side of the machine body 1, and an automatic feeding device 7 disposed inside the machine body 1; the automatic feeding device 7 includes a motor 71, the motor 71 is fixedly connected to the bottom of the inner wall of the machine body 1, a pressing block 72 is fixedly connected to the end of the output shaft of the motor 71, a fixing plate 73 is fixedly connected to the inner side wall of the machine body 1, and the side of the fixing plate 73... A hollow plate 74 is fixedly connected, and a sliding body 75 is slidably connected to the bottom of the inner wall of the hollow plate 74. A spring 76 is fixedly connected to the circumferential surface of the sliding body 75, and the end of the spring 76 away from the sliding body 75 is fixedly connected to the inner side wall of the hollow plate 74. A connecting plate 77 is fixedly connected to the circumferential surface of the sliding body 75, and a push plate 78 is fixedly connected to the bottom of the connecting plate 77. The circumferential surface of the crushing component 2 is provided with rotating crushing blades and fixed blades. By cooperating with the two types of blades, the crushing effect is improved, and the rotating crushing blades are protected during the crushing process of the material.

[0028] A support frame 5 is fixedly connected to the bottom of the machine body 1. A movable door 10 is hinged to the front side of the machine body 1. A guide plate 9 is fixedly connected to the bottom of the feeding plate 4. A filter plate 11 is fixedly connected to the inner wall of the machine body 1. The design of the guide plate 9 helps to prevent the material from splashing inside the machine body 1 after the material is crushed. At the same time, the design of the filter plate 11 helps to allow the material to fall to the top of the filter plate 11 after the crushing device 2 has finished crushing the material. At this time, the filter plate 11 filters out larger materials and impurities.

[0029] The side cross-section of the sliding body 75 is set to be circular, and the side cross-section of the extrusion block 72 is set to be elliptical. The sliding body 75 is located on the movement trajectory of the extrusion block 72. The design of the sliding body 75 is conducive to the sliding body 75 sliding at the bottom inside the hollow plate 74 when the sliding body 75 is subjected to the extrusion force of the extrusion block 72.

[0030] The initial state of the spring 76 is set to the relaxed state, the angle between the feed plate 4 and the inner side wall of the machine body 1 is greater than 90 degrees, the side section of the filter plate 11 is set to arc shape, and the design of the spring 76 is conducive to the spring 76 driving the slide body 75 to reset when the slide body 75 is no longer squeezed by the extrusion block 72.

[0031] Two guide plates 9 are provided and are symmetrical to each other along the vertical central axis at the bottom of the inner wall of the machine body 1. The push plate 78 is in contact with the bottom of the inner wall of the machine body 1. The design of the push plate 78 is conducive to the sliding body 75 sliding to drive the connecting plate 77 to move after the material is crushed, and at the same time drive the push plate 78 to move and push the material.

[0032] In this embodiment, the operator first starts the crushing device 2 located on the rear side of the machine body 1, and simultaneously puts material into the machine body 1 through the feed port 3 at the top of the machine body 1. At this time, the crushing device 2 crushes the material, and the crushed material falls to the bottom of the inner wall of the machine body 1. At the same time, the motor 71 fixed to the bottom of the inner wall of the machine body 1 is started, thereby driving the extrusion block 72 fixed to the end of the output shaft to rotate. When the extrusion block 72 rotates, it squeezes the sliding body 75 sliding on the bottom of the inner wall of the hollow plate 74, thereby causing the spring 76 fixed to the circumferential surface of the sliding body 75 to be in a taut state. At the same time, when the sliding body 75 slides, it drives the connecting plate 77 fixed to the circumferential surface to move. The movement of the connecting plate 77 drives the push plate 78 fixed to the bottom to move, pushing the crushed material to move. As the push plate 78 continues to move, the material is discharged through the discharge port 6 on the rear side of the machine body 1. When the extrusion block 72 stops squeezing the sliding body 75, the spring 76 drives the sliding body 75 to reset, thereby causing the push plate 78 to reset and reciprocate, continuously pushing the crushed material to move.

[0033] Example 2

[0034] like Figures 1 to 5 As shown, based on the same concept as in Embodiment 1 above, this embodiment also proposes that a cleaning device 8 be provided on the side of the guide plate 9. The cleaning device 8 includes a cleaning body 81, which is provided on the side of the guide plate 9. The above design is beneficial for cleaning the crushing device 2.

[0035] The rear side of the guide plate 9 is provided with a groove 82, and the inner side wall of the groove 82 is slidably connected to a limit block 83. The side section of the limit block 83 is fixedly connected to a connecting block 84. The above design is beneficial to facilitate the replacement by staff when the cleaning effect of the cleaning body 81 weakens.

[0036] The side section of the connecting block 84 is set to L-shape. The connecting block 84 is fixedly connected to the rear side of the cleaning body 81. The above design facilitates replacement by staff.

[0037] There are two cleaning bodies 81, which are symmetrical to each other along the vertical central axis at the bottom of the inner wall of the machine body 1. The cleaning bodies 81 are in contact with the side of the guide plate 9. The design of two cleaning bodies 81 is conducive to better cleaning of the cleaning bodies 81.

[0038] Multiple support legs 5 are provided and are symmetrical to each other along the vertical central axis at the bottom of the body 1. This design helps to enhance the stability of the body 1 during operation.

[0039] In this embodiment, during the crushing process, the crushing device rotates and contacts the cleaning body 81 to clean the impurities on the circumferential surface of the crushing device 2. When the cleaning body 81 is damaged during long-term use, the operator pulls the limiting block 83 that slides on the inner wall of the groove 82 to disengage the limiting block 83 from the inner wall of the groove 82, thereby preventing the cleaning body 81 from contacting the crushing device 2 and completing the replacement of the cleaning body 81.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
