[0028] The blade 201 is made of steel plate. The thickness of the blade 201 is 15-25 mm, the width of the blade 201 is 150-250 mm, and the length of the blade 201 is 1600-2200 mm. Figure 2As shown in the figure, one end of the blade 201 is fixed to the side of the bucket 103, and the blade 201 is arranged perpendicularly to the side of the bucket 103. In order to ensure the stability of the mowing assembly 2 when cutting stems and leaves, the blade 201 is fixed to the bucket 103 by welding, as shown in the figure. Figure 3 and Figure 4 As shown in the figure, the fixed end of the blade 201 is welded with a first fixing plate 203, the side of the first fixing plate 203 is welded to the side of the bucket 103, and the lower side of the first fixing plate 203 is welded and connected to the upper surface of the blade 201. A second fixing plate 204 is also arranged between the blade 201 and the first fixing plate 203. The second fixing plate 204 is a right-angled triangular plate, one of the right-angled edges of the second fixing plate 204 is welded and connected to the first fixing plate 203, and the other right-angled edge of the second fixing plate 204 is welded and connected to the upper surface of the blade 201, thereby ensuring the stability of the welding of the blade 201 and the bucket 103.

[0029] In this embodiment, the materials of the first fixing plate 203 and the second fixing plate 204 are both steel plates with a thickness of 20 mm. The thickness of the blade 201 is 20 mm, the width is 200 mm, and the length is 1800 mm. The width of the first fixing plate 203 is 200 mm, and the length is 200 mm. The width of the second fixing plate 204 is 180 mm, and the length is 200 mm.

[0030] In order to move the cut stems and leaves aside when the telescopic rotating arm 102 rotates to drive the mowing assembly 2 to work, and to avoid the blade 201 from deviating when the mowing assembly 2 rotates to work, the mowing assembly 2 also includes a fixing frame 202 in this embodiment. One side of the blade 201 is the cutting edge, and the other side of the blade 201 is the back. The cutting edge of the blade 201 faces outward, and the fixing frame 202 is arranged on the back side.

[0031] In order to make the excavator 1 walk better on the tidal wetland, the excavator 1 is a caterpillar type excavator in this embodiment.

[0032] The working principle of the tidal wetland Spartina alterniflora mowing device in this application is as follows:

[0033] The mowing assembly 2 is fixed on the bucket 103 of the excavator 1, the excavator 1 enters the tidal wetland, the telescopic rotary arm 102 is telescopic and rotated to drive the blade 201 in the mowing assembly 2 to rotate, the blade 201 removes the stems and leaves of the Spartina alterniflora when rotating, the mowing height is controllable, the neatness is good, and is preferably not more than 10 cm, the removed stems and leaves fall between the blade 201 and the fixed frame 202, so as to place the removed stems and leaves at the designated position, and avoid the removed stems and leaves from hindering the subsequent deep cleaning of the root system; because the root system of the Spartina alterniflora is too dense, after the root system of the Spartina alterniflora in the tidal wetland is deep cleaned, the bearing capacity of the tidal wetland decreases, and the excavator 1 has the possibility of sinking into the mud if directly working on the tidal wetland, therefore, when the root system of the Spartina alterniflora in the tidal wetland needs to be plowed and deeply buried, the mowing assembly 2 is separated from the bucket 103, the mowing assembly 2 is separated from the bucket 103 by cutting in the embodiment, and then the excavator 1 is placed on the dredging ship, the dredging ship enters the tidal wetland, the telescopic rotary arm 102 is telescopic and rotated to drive the bucket 103 to remove and deeply bury the remaining root system of the Spartina alterniflora, the root system of the Spartina alterniflora is damaged, and the damaged root system of the Spartina alterniflora is completely dead.

[0034] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application and not to limit them; although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that; the specific embodiments of the application can still be modified or some technical features can be replaced by equivalent; without departing from the spirit of the technical solutions of the present application, they should be covered in the technical solution range of the present application claimed.
