[0053] Example 1

[0054] The present application provides a harvester, which includes a shredder 3. The shredder 3 can be in a working state under certain working conditions to shred the straw; it can also be in an idle state, that is, a non-shredding state, under certain working conditions. Whether in the working state or the idle state, the shredder 3 is located on the main body 1 of the machine body and runs with the main body 1 of the machine body. Compared with the existing ones, when in the idle state, it requires multiple people to cooperate to disassemble the shredder 3 from the main body 1 of the machine body. In the present application, the working mode can be quickly switched without disassembly; in addition, there is no need for multiple people to cooperate, and a single person can operate it, saving manpower. The following will be combined with Figures 1 - 4 as shown, a harvester provided by the present application will be described in detail.

[0055] In this embodiment, in combination with Figure 1 as shown, the harvester includes a main body 1 of the machine body, a lifting assembly 2 and a shredder 3.

[0056] Specifically, both the lifting assembly 2 and the shredder 3 are arranged on the main body 1 of the machine body; further, the lifting assembly 2 is arranged at one end of the main body 1 of the machine body in the height direction. Preferably, the lifting assembly 2 is arranged on the drum cover 20; the shredder 3 is arranged at one end of the main body 1 of the machine body in the length direction, that is, in combination with Figure 1 as shown, the lifting assembly 2 is arranged above the shredder 3.

[0057] Specifically, the lifting assembly 2 is detachably connected to the shredder 3, that is, the lifting assembly 2 can be connected to the shredder 3 or not. When the lifting assembly 2 is connected to the shredder 3, the lifting assembly 2 can drive the shredder 3 to move in the first direction 4, so that the shredder 3 can be switched between the working state and the idle state; the first direction 4 herein refers to the vertically upward and vertically downward directions. Further, under normal conditions, such as the state in Figure 1 , the shredder 3 is in the working state, that is, the shredder 3 is close to the ground and the shredder 3 can shred straw; when the shredder 3 is not required to work, the lifting assembly 2 drives the shredder 3 to move in the vertically upward direction ( Figure 2 shows the process diagram of the lifting assembly 2 driving the shredder 3 to move upward), so as to be able to lift the shredder 3 and keep it away from the ground, so that the shredder 3 is in the non-working state ( Figure 4 is the schematic diagram of the non-working state); when the shredder 3 is required to work again, the lifting assembly 2 only needs to drive the shredder 3 to move in the vertically downward direction.

[0058] In summary, in some working conditions, it can also be in the idle state, that is, the non-shredding state; whether in the working state or the idle state, the shredder 3 is located on the main body 1 of the machine and runs with the main body 1 of the machine; compared with the existing one, when in the idle state, it requires multiple people to work together to disassemble the shredder 3 from the main body 1 of the machine. In this application, the working mode can be quickly switched without disassembly; in addition, there is no need for multiple people to work together, and a single person can operate it, saving manpower.

[0059] In this embodiment, further, in combination with Figure 2 and Figure 3 as shown, the lifting assembly 2 includes a lifting motor 5 and a towing rope 6.

[0060] Specifically, the towing rope 6 extends in the first direction 4. One end of the towing rope 6 is connected to the output shaft of the lifting motor 5 and the other end is detachably connected to the shredder 3. Preferably, the lifting motor 5 is a servo motor.

[0061] Further, when the towing rope 6 is connected to the shredder 3 and the lifting motor 5 is started to rotate in the second direction 7, the shredder 3 can be driven to switch from the working state to the idle state. Here, the second direction 7 refers to the clockwise direction, that is, when the output shaft of the lifting motor 5 rotates clockwise, the towing rope 6 can be wound around the output shaft, that is, the towing rope 6 is shortened in the first direction 4, so as to lift the shredder 3 from the ground, making the shredder 3 switch from the working state to the idle state. When the driving lifting motor 5 rotates in the third direction 8, the shredder 3 can be driven to switch from the idle state to the working state. Here, the third direction 8 refers to the counterclockwise direction, that is, when the output shaft of the lifting motor 5 rotates counterclockwise, the towing rope 6 can be released from the output shaft, that is, the towing rope 6 is elongated in the first direction 4, so as to drop the shredder 3 to a position close to the ground, making the shredder 3 switch from the idle state to the working state.

[0062] It should be noted that: in this embodiment, the driving structure of the lifting motor 5 is adopted, but the present application is not limited to the above structure, and it can also be a cylinder structure.

[0063] To sum up, in this embodiment, through the cooperation of the lifting motor 5 and the towing rope 6, the switching between the working state and the non-working state of the shredder 3 can be realized. Only one person needs to turn on the lifting motor, without the need for multiple people to cooperate, and the operation is simple.

[0064] In this embodiment, further, as shown in Figure 3 a hanging portion 9 protrudes from one side of the shredder 3 facing the lifting assembly 2; the towing rope 6 is detachably connected to the hanging portion 9.

[0065] Further, the hanging portion 9 is a hanging ring 10, and a hook 11 is provided on one side of the towing rope 6 facing the shredder 3; the hook 11 is detachably connected to the hanging ring 10. That is, in the actual use process, the hook 11 can be hung on the hanging ring 10 to realize the connection between the lifting assembly 2 and the shredder 3; the hook 11 can also be removed from the hanging ring 10 to realize the separation between the lifting assembly 2 and the shredder 3. In this way, even if one of the lifting assembly 2 or the shredder 3 is damaged and needs to be repaired, it is not necessary to disassemble both of them, and only the damaged one needs to be disassembled.

[0066] In this embodiment, further, as shown in Figure 3 the harvester further includes a telescopic assembly 12.

[0067] Specifically, the telescopic end of the telescopic assembly 12 is connected to the lifting assembly 2, and the telescopic assembly 12 can drive the lifting assembly 2 to move in the fourth direction 13, so that the lifting assembly 2 extends above the shredder 3 or retracts to abut against the telescopic assembly 12. Here, the fourth direction 13 refers to the length direction of the machine body main body 1. Preferably, the telescopic assembly 12 is arranged on the drum cover 20.

[0068] Further, in combination with Figure 3 as shown, the telescopic assembly 12 includes an electric push rod 14; the electric push rod 14 has a telescopic end, and the telescopic end of the electric push rod 14 is connected to the lifting assembly 2, that is, the electric push rod 14 is fixedly connected to the housing of the lifting motor 5. When the electric push rod 14 is started, the electric push rod 14 can drive the lifting assembly 2 to move in the fourth direction 13, that is, when the electric push rod 14 is started, the electric push rod 14 can drive the lifting motor 5 to extend along the length direction of the main body of the host, so that the lifting motor 5 is located above the chopper 3.

[0069] Further, in combination with Figure 3 as shown, the telescopic assembly 12 further includes a housing 15. The housing 15 is provided with an installation space, the electric push rod 14 is arranged in the installation space, and the telescopic end of the electric push rod 14 can extend or retract from the housing 15 in the fourth direction 13.

[0070] During the actual use process, when the telescopic end of the electric push rod 14 extends out of the housing 15, it can drive the lifting assembly 2 to be located above the chopper 3; when the telescopic end of the electric push rod 14 retracts into the housing 15, it can make the lifting assembly 2 abut against the housing 15.

[0071] Further, in combination with Figure 3 as shown, the telescopic assembly 12 further includes a first sleeve 16 and a second sleeve 17; the first sleeve 16 is embedded in the housing 15 and extends in the fourth direction 13. Preferably, the first sleeve 16 is welded in the housing 15. One end of the second sleeve 17 is slidably arranged in the first sleeve 16 and the other end is connected to the lifting assembly 2.

[0072] During the actual use process, when the electric push rod 14 drives the lifting assembly 2 to move in the fourth direction 13, the second sleeve 17 can move in the first sleeve 16 in the fourth direction 13, that is, the first sleeve 16 can be understood as a slide rail of the second sleeve 17, that is, the second sleeve 17 can slide on the first sleeve 16.

[0073] In summary, considering that the lifting motor 5 has a certain weight, then only using the electric push rod 14 may not be sufficient to extend the lifting motor 5 above the chopper 3, or there may be a risk of the lifting motor 5 falling. In this embodiment, the first sleeve and the second sleeve are just arranged. The second sleeve is connected to the lifting motor 5, so that the second sleeve provides a supporting force for the lifting motor 5 to a certain extent and can prevent the lifting motor 5 from falling.

[0074] It should be noted that: the first sleeve and the second sleeve are used as a set of auxiliary components. During the actual use process, multiple sets can be set, and multiple sets of auxiliary components are arranged at intervals along the width direction of the main body of the machine.

[0075] It should also be noted that: Considering the stability of the connection, the second sleeve and the lifting motor 5 can be connected by means of a connecting seat, that is, a connecting seat is welded to the outer surface of the lifting motor 5, and the second sleeve is welded to the connecting seat.

[0076] In this embodiment, further, the telescopic assembly 12 further includes a control switch 18; the control switch 18 is electrically connected to the electric push rod 14 and can control the start and stop of the electric push rod 14.

[0077] Specifically, the electric push rod 14 on this side is electrically connected to the control switch 18, and there is no improvement in the control program. It only uses the existing control program to realize the start and stop of the control switch 18 controlling the electric push rod 14. In this application, it is indicated that the control switch 18 is electrically connected to the electric push rod 14.

[0078] In this embodiment, in combination with Figure 1 as shown, the harvester further includes a toolbox 19, and the toolbox 19 is arranged above the chopper 3 when the chopper 3 is in the working state. When the chopper 3 needs to be converted to the idle state, the toolbox 19 needs to be manually removed.
