[0053] The following combination Figures 1-14 , some embodiments of the present invention are described in detail. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0054] In the first aspect, the utility model provides a straw processing device, such as Figures 1 to 6As shown, it includes a shell 1, an adjusting device 5, a switching slide assembly 2, a chopping assembly 6 and a scattering assembly 7; the switching slide assembly 2 is arranged in the shell 1; the adjusting device 5 passes through the shell 1 and is connected to the switching slide assembly 2; the switching slide assembly 2 is arranged above the chopping assembly 6, and the scattering assembly 7 is arranged behind the chopping assembly 6; the switching slide assembly 2 includes a front support 3, a rear support 4, a straw slide 24 and a rotating shaft 12; one end of the straw slide 24 is connected to the rotating shaft 12, and the other end is driven by the rotating shaft 12 to be connected to the front support 3, covering the chopping assembly 6 to form a non-chopping state, or can be connected to the rear support 4 to form a chopping state.

[0055] In this embodiment, the adjusting device 5 adjusts the rotating shaft 12 of the switching slide assembly 2, so that the rotating shaft 12 rotates to drive the straw slide 24 to rotate, changing the connection state between the straw slide 24 and the front support 3 or the rear support 4, thereby changing the switching between the shredding or non-shredding state.

[0056] Specifically, in this embodiment, when the straw slide 24 is connected to the front support 3, it can cover the top of the chopping component 6 to prevent the incoming material from entering the chopping component 6, thereby being in a non-chopping state; when the straw slide 24 is connected to the rear support 4, it blocks the rear opening of the shell 1 and opens the top of the chopping component 6, so that the incoming material can directly enter the chopping component 6 and cannot be discharged from the discharge port, thereby being in a chopping state.

[0057] When switching the state, it can be achieved by simply driving the rotating shaft 12 to rotate externally through the adjusting device 5, without the need to disassemble or assemble other components such as the chopping component 6. The whole process is simple, fast, efficient and safe.

[0058] In an optional embodiment, if Figure 13 and Figure 14 As shown, a shaft sleeve 26 is provided at one end of the straw slide plate 24 , and the shaft sleeve 26 is sleeved on the rotating shaft 12 .

[0059] In this embodiment, a shaft sleeve 26 is provided on the rotating shaft 12, which is connected to the straw slide 24 through the shaft sleeve 26. There are pin holes 20 at both ends of the shaft sleeve 26, and there are corresponding pin holes 20 on the rotating shaft 12. After the fixing pin is inserted into the shaft sleeve 26 and the pin holes 20 on the rotating shaft 12, the shaft sleeve 26 and the rotating shaft 12 are connected together, so that when the adjusting device 5 drives the rotating shaft 12 to rotate, it can also drive the shaft sleeve 26 to rotate, thereby driving the straw slide 24 to swing, changing the chopped or non-chopped state.

[0060] In an optional embodiment, a guide plate 25 is provided on the outer wall of the shaft sleeve 26 , one end of the guide plate 25 is connected to the straw slide plate, and the other end is tangent to the outer wall of the shaft sleeve 26 .

[0061] In this embodiment, the guide plate 25 and the straw slide 24 are respectively arranged on opposite sides of the sleeve 26, and are tangent to the outer wall of the sleeve 26, so that there is no dead angle between the guide plate 25, the straw slide 24 and the sleeve 26, avoiding blockage of incoming materials and facilitating cleaning of the straw slide 24.

[0062] In an optional embodiment, the other end of the straw slide plate 24 is provided with a bonding plate 27 that is bonded to the end surface of the front support 3 .

[0063] In this embodiment, the straw slide plate 24 has a certain degree of bending, which can better cover the chopping component 6.

[0064] At the same time, in this embodiment, the straw slide plate 24 cooperates with the bonding plate 27 to form a double-bending structure, which can better fit with the end face of the front support 3, ensuring that no material enters the chopping component 6 when the straw slide plate 24 is connected to the front support 3.

[0065] Specifically, in this embodiment, side supports 8 are provided on opposite sides of the inner wall of the shell 1. The side supports 8, the front support 3 and the rotating shaft 12 jointly support the straw slide 24 to form a supporting frame structure, thereby ensuring the supporting stability of the straw slide 24.

[0066] In this embodiment, when the straw slide plate 24 is connected to the rear support 4 , the other side of the laminating plate 27 is brought into contact with the rear support 4 .

[0067] It can be seen from the above that in this embodiment, the straw slide plate 24 is connected to the front support 3 or the rear support 4 in an abutting manner.

[0068] It can be understood that the connection method between the straw slide 24 and the front support 3 or the rear support 4 can be abutment, but it is not limited to abutment. It can also be other connection methods, such as snap-on, etc., as long as it can achieve stable support between the straw slide 24 and the front support 3 or the rear support 4.

[0069] In an optional embodiment, if Figure 12 As shown, the front support 3 includes an installation side plate 21, a support plate 22 and a material guide plate 23; the installation side plates 21 are provided at both ends of the same side of the support plate 22, and the support plate 22 is used to fit with the fitting plate 27; the material guide plate 23 is provided above the installation side plate 21, and can guide the material to the straw slide plate 24.

[0070] In this embodiment, the front support 3 is a frame structure, and the mounting side plates 21 at both ends thereof serve to connect the support plate 22 and the material guide plate 23 together to form an integral support.

[0071] The support plate 22 is placed vertically or has a certain inclination angle, and fits with the fitting plate 27 on the straw slide 24. The inclination angle can provide certain vertical and horizontal support for the fitting plate 27 of the straw slide 24. It is fixed inside the shell 1 through the mounting side plates 21 at both ends to ensure stability during support.

[0072] The guide plate 23 is arranged horizontally or has a certain inclination angle. It is arranged above the support plate 22 and extends above the laminating plate 27 or the straw slide 24. The incoming material flows to the laminating plate 27 and the straw slide 24 through the guide plate 23.

[0073] When the guide plate 23 has a certain inclination angle, its lower end is in the direction of the laminating plate 27 or the straw slide plate 24 , which can facilitate the incoming material to flow to the top of the laminating plate 27 or the straw slide plate 24 .

[0074] In an optional embodiment, if Figure 9 、 Figure 10 and Figure 11 As shown, the adjusting device 5 includes a limit seat 13, a limit pin 16, an adjusting handle 17 and a limit spring 15; the limit seat 13 is fixedly arranged on the outer wall of the shell 1; a limit hole is provided on the limit seat 13, and the limit pin 16 is inserted into the limit hole; the limit spring 15 is sleeved on the limit pin 16 and connected to the limit seat 13, for applying a force to the limit pin 16 in the direction of the limit seat 13; the adjusting handle 17 is connected to one end of the rotating shaft 12, and the limit pin 16 can be hung on the adjusting handle 17 after compressing the limit spring 15.

[0075] In this embodiment, the limit seat 13 is fixedly arranged on the outer wall of the shell 1, and the rotating shaft 12 passes through the limit seat 13 and is fixedly connected to the adjustment handle 17. By rotating the adjustment handle 17, the rotating shaft 12 can be driven to rotate, and further drive the straw slide 24 to swing, thereby realizing the switching between the shredding state and the non-shredding state.

[0076] In this embodiment, the limit pin 16 is inserted into the limit seat 13, and the limit pin 16 is positioned by the limit spring 15 to prevent the limit pin 16 from detaching from the limit seat 13. At the same time, when the limit pin 16 is connected to the adjustment handle 17, the limit spring 15 can apply a force to the limit pin 16 to ensure the connection stability between the limit pin 16 and the adjustment handle 17, and prevent the adjustment handle 17 from shaking after being rotated to the set position and changing the chopping state of the straw processing device.

[0077] In an optional embodiment, the limit seat 13 is U-shaped, and the limit spring 15 is arranged inside the limit seat 13. One end of the limit spring 15 abuts against the inner wall of the limit seat 13, and the other end abuts against the limit baffle 14 mounted on the limit pin 16.

[0078] In this embodiment, the limit seat 13 is set to be U-shaped, one end of the limit spring 15 has a limit baffle 14, and a positioning pin is provided on the limit pin. The positioning pin is set on the side of the limit baffle away from the limit spring. The positioning of the limit baffle 14 is achieved by inserting the positioning pin 18 on the limit pin 16, and the positioning of the limit spring 15 is further achieved.

[0079] Specifically, in this embodiment, the limiting baffle 14 is provided at one end of the limiting spring 15 away from the adjusting handle 17 , and can drive the limiting pin 16 to move toward the inside of the housing 1 , that is, away from the adjusting handle 17 .

[0080] Pull the limit pin 16, and the limit pin 16 compresses the limit spring 15 under the action of the limit baffle 14, so that the limit pin 16 disengages from the adjusting handle 17, and rotates the limit pin 16 so that its hook 19 part is separated from the adjusting handle 17, and the limit pin 16 is released. Under the action of the limit spring 15, the limit pin 16 moves between the adjusting handle 17 and the shell 1. At this time, the adjusting handle 17 can be rotated. When the adjusting handle 17 is rotated to the set position, the limit pin 16 is pulled so that the hook 19 at the outer end of the limit pin 16 moves to the outside of the adjusting handle 17, and the limit pin 16 is rotated to fit the hook 19 with the adjusting handle 17. The limit pin 16 is released, and under the action of the limit spring 15, the hook 19 can hook on the adjusting handle 17 to prevent the adjusting handle 17 from rotating, thereby realizing the rotation limit of the adjusting handle 17.

[0081] In an optional embodiment, if Figure 7 and Figure 8 As shown, the shredding assembly 6 includes a fixed knife assembly 11, a movable knife assembly 10 and a power transmission structure 9; the fixed knife assembly 11 and the movable knife assembly 10 are arranged in parallel in the shell 1; the power transmission structure 9 is connected to the movable knife assembly 10 to provide rotational power for the movable knife assembly 10.
