[0025] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] like Figure 1 to Figure 6As shown, this embodiment proposes a trenching machine for garden construction, including a base 3, a rotating base 4 and a soil covering plate 5, the rotating base 4, the top of the base 3 is fixed with a second fixed seat 306 by welding, the inside of the second fixed seat 306 is rotatably connected with a second rotating block 305, the top of the second rotating block 305 is fixed with a first telescopic rod 303 by welding, the outer side of the first telescopic rod 303 is sleeved with a first spring 304, the top of the first spring 304 is tightly provided with a first rotating block 302, the outer side of the first rotating block 302 is rotatably connected with a first fixed seat 301, the first fixed seat 301 is fixedly connected to the top of a clamping plate 307, and the clamping plate 307 is rotatably connected to the base 3.

[0028] In this embodiment, when the base 3 is placed on the ground, the clamping plate 307 is unfolded and fixedly connected to the second rotating arm 203 by bolts. At this time, when the driving source 1 tilts, the first rotating block 302 inside the first fixed seat 301 squeezes the first spring 304, and the other end of the first spring 304 squeezes the second rotating block 305, thereby buffering and shock-absorbing the clamping plate 307 to prevent the driving source 1 from excessively tilting.

[0029] Example 2

[0030] like Figure 3 to Figure 6 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the top end of the rotating base 4 is rotatably connected with a fixed block 401, the outer side of the fixed block 401 is sleeved with a rotating rod 402, the outer side of the rotating rod 402 is tightly provided with a second telescopic rod 403, the outer side of the second telescopic rod 403 is sleeved with a second spring 404, the outer side of the second telescopic rod 403 is provided with a tightening ring 405, the inner part of the tightening ring 405 is provided with a circular hole, the second telescopic rod 403 slides inside the circular hole of the tightening ring 405, the second telescopic rod 403 slides forward inside the tightening ring 405, and then the soil shielding plate 5 is slapped, so as to facilitate the slapping and crushing of the soil inside the soil shielding plate 5, the inner part of the soil shielding plate 5 is rotatably connected with a third rotating block 501, the outer side of the third rotating block 501 is sleeved with a transmission rod 503, The transmission rod 503 is rotatably connected inside the soil shielding plate 5, and a rocker arm 502 is sleeved on the outer side of the third rotating block 501. The outer side of the rocker arm 502 is rotatably connected to a digging knife group 504. The digging knife 504 rotates on the outer side of the rocker arm 502. At this time, the downwardly inclined second rotating arm 203 drives the digging knife 504 on the outer side of the rocker arm 502 to dig the soil. At this time, the rotating digging knife 504 brings the soil from the deep soil to both sides of the opened ditch. A mudguard 505 is provided on the rear side of the soil shielding plate 5, and a connecting buckle 506 is sleeved on the outer side of the mudguard 505. The second rotating arm 203 is provided on the outer side of the connecting buckle 506. The second rotating arm 203 is rotatably connected to the connecting rod 202 on the outer side, and the connecting rod 202 is rotatably connected to the first rotating arm 201 on the outer side. The driving source 1 drives the connecting block 2 to move.

[0031] In this embodiment, the rotating digging knife 504 brings soil out from the deep soil to both sides of the opened ditch. At this time, the soil shielding plate 5 protects the driving source 1 and the staff to prevent the splashing soil from damaging the driving source 1. At this time, the third rotating block 501 pushes the soil on both sides of the soil ditch to the vicinity to prevent the soil from blocking the movement of the driving source 1.

[0032] The working principle of this utility model:

[0033] First, the staff hangs the connecting block 2 on the rear side of the driving source 1 and fixes it. When it is necessary to dig the soil downward to open a ditch, the connecting block 2 pushes the first rotating arm 201 to slide deep into the soil, and the first rotating arm 201 drives the connecting rod 202 to slide forward, and the connecting rod 202 drives the second rotating arm 203 to slide toward the front side of the soil, and the connecting buckle 506 is fixedly connected to the soil shielding plate 5. The transmission rod 503 controls the rocking arm 502 to rotate. At this time, the downwardly inclined transmission rod 503 drives the digging knife 504 on the outside of the rocking arm 502 to dig the soil. At this time, the rotating digging knife 504 brings the soil out from the deep soil to both sides of the opened ditch. At this time, the soil shielding plate 5 protects the driving source 1 and the staff to prevent the splashing soil from damaging the driving source 1. At this time, the third rotating block 501 pushes the soil on both sides of the soil ditch to the vicinity to prevent the soil from blocking the movement of the driving source 1.

[0034] And when the soil inside the soil shielding plate 5 accumulates a lot, the fixed block 401 at the top of the rotating base 4 drives the rotating rod 402 to rotate, thereby squeezing the second telescopic rod 403 and the second spring 404 on the outside, and the second telescopic rod 403 slides forward inside the clamping ring 405, thereby slapping the soil shielding plate 5, which is convenient for slapping and crushing the soil inside the soil shielding plate 5. When the driving source 1 is moving forward and encounters a steep road surface, the base 3 can be placed on the ground, and the clamping plate 307 can be unfolded and fixedly connected with the second rotating arm 203 by bolts. At this time, when the driving source 1 tilts, the first rotating block 302 inside the first fixed seat 301 squeezes the first spring 304, and the other end of the first spring 304 squeezes the second rotating block 305, thereby buffering and shock-absorbing the clamping plate 307 to prevent the driving source 1 from excessively tilting.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
