[0046] The specific implementation modes of the present invention are further described in detail below with reference to the accompanying drawings.

[0047] Combination Figure 1 , Figure 2 and Figure 3 It can be seen that the multifunctional grass shredder includes a functional area 1 and a driving area 2, wherein the functional area 1 is detachably arranged on the driving area 2, and the driving area 2 includes a driving source 31 and a connecting part connected to the driving source 31 and outputting power. Therefore, in actual use, the driving source 31 drives the connecting part and drives the operation of the functional area 1 through the connecting part.

[0048] Moreover, the connection part includes a connection shaft 1 3 and a connection shaft 2 4, and the connection shaft 1 3 and the connection shaft 2 4 connect different functional areas. Taking grass chopping and grass cutting as an example, if you want to chop grass, you only need to place the grass chopping component 5 at the front end of the driving area 2 through the connection shaft 1 3. If you want to cut grass, you only need to place the grass cutting component 6 at the front end of the driving area 2 through the connection shaft 2 4. That is, by replacing the functional area 1, the grass chopper is given multiple functions, realizing multiple uses of one machine.

[0049] like Figure 8 As shown, a gear 1 27 is sleeved on the connecting shaft 1 3, and a gear 2 28 is sleeved on the connecting shaft 2 4, and the gear 1 27 and the gear 2 28 are meshed with each other.

[0050] Therefore, in actual use, first the connecting shaft 1 3 rotates to drive the gear 1 27 to rotate, which in turn drives the gear 2 28 to rotate, thereby driving the connecting shaft 2 4 to rotate.

[0051] Moreover, the diameters of gear 1 27 and gear 2 28 are different, so there is a transmission ratio, so the rotation speed and transmission power of gear 1 27 and gear 2 28 are different. This is because the power requirements of each functional area may be different, so different connecting shafts are used to correspond to different functional areas, so as to ensure the corresponding power. In addition, due to the differential transmission of gear 1 27 and gear 2 28, the steering of functional area 1 is flexible and smooth.

[0052] like Figure 7 As shown, it can be seen that the driving area 2 includes a driving assembly 29, wherein the driving assembly 29 is composed of some components that drive the functional area 1 to operate. Moreover, the driving assembly includes a placement box 29, and the driving shaft 30, the connecting shaft 1 3 and the connecting shaft 2 4 are all arranged at one end of the placement box 29. Moreover, a connecting portion is arranged at the front end of the placement box 29, and a driving shaft 30 is arranged at the rear end of the placement box 29, and the driving shaft 30 is connected to the connecting shaft 1 3.

[0053] The driving source 31 is composed of related components including a motor. The driving source 31 is provided with an output shaft 32 , and the output shaft 32 is connected to the driving shaft 30 via a pulley assembly 33 .

[0054] Therefore, in actual use, the driving source 31 first drives the output shaft 32 to rotate, then drives the pulley assembly 33 to operate, and then drives the driving shaft 30 to rotate, thereby driving the connecting shaft 3 to rotate. It can be seen that it is mainly driven by the motor, so there is no need for manual pushing, which is convenient and labor-saving. At the same time, when pushing manually, the wheel 45 will be replaced according to the terrain to reduce the thrust of manual pushing, but the present invention can avoid this situation because it is driven by the motor, and can provide sufficient thrust according to the speed of the motor.

[0055] Combination Figure 2 , Figure 3 , Fig.10 and Fig.11 It can be seen that the driving area 2 is provided with a handle 34, which can be held and pushed manually by the user. At the same time, a push rod 35 is provided on the handle 34, and the operation of the functional area 1 can be turned on or off by pushing the push rod 35. Therefore, when the user reverses the present invention, the push rod 35 can be pushed to turn off the operation of the functional area 1, thereby ensuring the safety of the user and the people around the present invention while saving energy.

[0056] The specific structure is as follows: first, the push rod 35 is connected to the clamping assembly 36 through an electric wire or a connecting rod, and the clamping assembly 36 includes a clamping piece 37. At the same time, a gear 38 is provided on the connecting shaft 1 3, and the connecting shaft 1 3 is connected to the driving shaft 30 through the gear 38, and the gear 38 is provided with a groove 39, and the clamping piece 37 is clamped in the groove 39.

[0057] Therefore, in actual use, the push rod 35 can be pushed to move the gear 3 38 and then separate the connecting shaft 1 3 and the driving shaft 30, thereby realizing the operation of closing the functional area 1. When the push rod 35 is pushed in the opposite direction to move the gear 3 38 and then connect the connecting shaft 1 3 and the driving shaft 30, the operation of opening the functional area 1 is realized.

[0058] When connected by wires, it is somewhat similar to the braking principle, such as Fig.11 It can be seen that the clamping assembly 36 includes a connecting rod 1 and a connecting rod 2, and the connecting rod 1 and the connecting rod 2 are connected by a connecting rod, and the connecting rod 2 is provided with a clamping member 37. By pushing the push rod 35, the connecting rod 1 is pulled to rotate and drive the connecting rod 2 to rotate, and the gear 3 38 is pushed to connect or separate the connecting shaft 1 3 and the driving shaft 30.

[0059] When connected by a connecting rod, Fig.10 It can be seen that the clamping assembly 36 includes a connecting rod 1 and a connecting rod 2, and the connecting rod 1 and the connecting rod 2 are connected by a connecting rod, and the connecting rod 2 is provided with a clamping member 37. By pushing the push rod 35, the connecting rod is deflected, thereby driving the connecting rod 1 to rotate, and at the same time, the rotation of the connecting rod 1 drives the connecting rod to rotate the connecting rod 2, and pushes the gear 3 38 to connect or separate the connecting shaft 1 3 and the driving shaft 30.

[0060] like Fig. 9 As shown, it can be seen that the connection between the driving shaft 30 and the connecting shaft 1 3 is specifically as follows: first, the driving shaft 30 is provided with a gear 40, and a plurality of protrusions 1 41 are provided on one side of the gear 40, and a plurality of protrusions 2 42 are provided on one side of the gear 38, and the protrusions 1 41 and the protrusions 2 42 are abutted against and engaged with each other, thereby connecting the driving shaft 30 and the connecting shaft 1 3. That is, a simple connection structure is used for connection, which can ensure the stability of the structure and is easy to process and install.

[0061] like Fig.12As shown, a rotating rod 43 is provided in the placement box 29, and wheels 45 are provided at both ends of the rotating rod 43, and a gear 5 46 is sleeved thereon. At the same time, the connecting shaft 1 3 includes a worm area 44, which meshes with the gear 5 46 through the worm area 44, so that when the connecting shaft 1 3 rotates, the worm area 44 can be driven to rotate, and then the gear 5 46 can be rotated, and then the wheel 45 can be driven to rotate. It can be said that one shaft drives multiple components, which can drive the operation of the functional area 1 and drive the wheel 45 to rotate, thereby reducing the internal parts, and reducing the weight and volume of the present invention, so that it can be convenient for users to use.

[0062] At the same time, since the functional area 1 is detachable, even if the functional area 1 is removed, that is, the grass-chopping component 5 or the grass-cutting component 6 is removed, the vehicle can still be driven.

[0063] Moreover, when the functional area 1 is a grass-chopping component 5, the grass-chopping component 5 includes a rotating knife component and a transmission component 8, wherein the rotating knife component plays the role of chopping grass, and the transmission component 8 plays the role of transmitting the power of the driving area 2 to the rotating knife component. At the same time, the transmission component 8 can be selected as a pulley drive or a chain drive, etc.

[0064] Combined with Figure 2 , Figure 4 and Figure 5 It can be seen that the connection structure between the grass-chopping component 5 and the connecting shaft 1 3 is as follows: first, the grass-chopping component 5 includes a connecting member 7, and the connecting member 7 is provided with a connecting hole 1 9 and a connecting hole 2 10, and the transmission component 8 includes a connecting shaft 3 11. Therefore, when connected, the connecting shaft 1 3 is clamped in the connecting hole 1 9, and the connecting shaft 3 11 is clamped in the connecting hole 2 10.

[0065] Combined with Figure 5 and Figure 6 It can be seen that the connecting member 7 is provided with a bevel gear 12 and a bevel gear 2 13, and the bevel gear 1 12 and the bevel gear 2 13 are respectively provided with a connecting hole 1 9 and a connecting hole 2 10, and the bevel gear 1 12 and the bevel gear 2 13 are meshed with each other. Therefore, the rotation of the connecting shaft 1 3 is transmitted to the connecting shaft 3 11 through the rotation between the bevel gear 1 12 and the bevel gear 2 13.

[0066] Moreover, the specific connection structure between the connecting shaft 3 and the connecting hole 9 is as follows: first, a plurality of convex strips 15 are arranged at the front end of the connecting shaft 3, and a plurality of grooves 14 are opened between the convex strips 15; meanwhile, a protrusion 18 is arranged in the connecting hole 9, and connecting grooves 20 are respectively opened between the protrusions 18.

[0067] At the same time, the specific connection structure between the connecting shaft three 11 and the connecting hole two 10 is: first, a plurality of convex strips three 16 are arranged at the front end of the connecting shaft three 11, and a plurality of grooves three 17 are opened between the convex strips three 16; at the same time, a protrusion three 19 is arranged in the connecting hole two 10, and a connecting groove three 21 is opened between the protrusions three 19.

[0068] Therefore, when connecting, the protrusion 18 and the protrusion 3 19 are respectively engaged in the groove 14 and the groove 3 17, and the convex strip 15 and the convex strip 3 16 are respectively engaged in the connection groove 1 20 and the connection groove 3 21, thereby connecting the connection shaft 1 3 and the connection hole 1 9 and the connection shaft 3 11 and the connection hole 2 10. That is, the connection is made by using a simple connection structure, which can ensure the stability of the structure and is easy to process and install.

[0069] Moreover, in actual use, the driving area 2 first drives the connecting shaft 3 to rotate, thereby driving the bevel gear 12 to rotate, and at the same time the bevel gear 12 rotates to rotate the bevel gear 2 13, thereby driving the transmission assembly 8 to transmit, and the transmission assembly 8 drives the rotating knife assembly to rotate to chop grass.

[0070] like Figure 3 As shown, when the functional area 1 is a grass cutting assembly 6, the grass cutting assembly 6 includes a scissor assembly and a connecting pipe 24, wherein the scissor assembly plays a role of grass cutting, and its principle can refer to a lawn mower of Patent No. 2016100489464. At the same time, the connecting pipe 24 is used to transmit the power of the connecting shaft 24 to the scissor assembly so that the scissor assembly can be operated.

[0071] At the same time, the connecting tube 24 is used to connect the connecting shaft 24, and has a hole built in due to its own properties. Specific connection structure: First, the front end of the connecting shaft 24 is provided with a plurality of convex strips 22, and a plurality of grooves 23 are opened between the convex strips 22, and at the same time, the inner side of the connecting tube 24 is provided with protrusions 25, and connection grooves 26 are opened between the protrusions 25.

[0072] Therefore, when connecting, the connecting shaft 24 is clamped in the connecting pipe 24, and the protrusion 2 is clamped in the groove 23, and the convex strip 22 is clamped in the connecting groove 26. That is, a simple connection structure is used for connection, which can ensure the stability of the structure and is easy to process and install.

[0073] Moreover, what is mentioned above are two connecting axes, but it can also be three, four, etc., so as to have three functional areas 1 or four functional areas 1, etc., thereby realizing the interchange of more functions.

[0074] The specific working process of this program is as follows:

[0075] If you want to chop grass, you only need to place the chopping component 5 at the front end of the driving area 2 through the connecting shaft 1 3. If you want to mow grass, you only need to place the mowing component 6 at the front end of the driving area 2 through the connecting shaft 2 4. That is, by changing the functional area 1, the lawn mower is given multiple functions, realizing multiple uses of one machine.

[0076] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
