Description

Technical Field

[0001] The utility model belongs to the field of garden engineering, and more specifically, relates to a ditching device for greening construction. Background Art

[0002] Landscaping construction is an engineering project that uses civil engineering technology and landscape art to transform the topography of the land to plant trees, flowers and plants, in order to create an artificial landscape that is integrated with the natural environment. Landscaping can effectively reduce the urban heat island effect and improve the urban environment. At present, in the trenching operations for tree planting in landscaping construction, disc trenchers are mostly used for continuous crushing and excavation of the land. Due to the fixed width of the excavation disc, the disc trencher can only dig a trench of a fixed width when digging the land. If a wider trench is to be opened, the excavation disc of the corresponding width needs to be replaced. It can be seen that the disc movement structure of the traditional disc trencher is fixed, and it is impossible to change the trenching range in time according to the changing requirements of the trench excavation width. The excavation disc replacement operation also seriously affects the trenching efficiency. In addition, the disc structure of the disc trencher is exposed, and the dust formed during the excavation process will fly into the air, damaging the air environment quality during construction.

The motor shaft of the displacement motor 25 is installed with a threaded rod 16. The outer side of the support rod 17 is slidably connected to the sliding sleeve 18, and the upper side of the sliding sleeve 18 is welded to the sliding column 19. The front side of the sliding column 19 is hinged to the hydraulic cylinder 20, and the front end of the telescopic rod of the hydraulic cylinder 20 is hinged to the support rod 30. The rear end of the support rod 30 is hinged to the front side of the sliding sleeve 18; the left side of the support rod 30 is rotatably connected to the transmission rod 21, and the support rod The left side of the rod 30 is welded with a dust cover 1, and the bottom of the dust cover 1 is welded with a retaining shell 9 near the front end. The upper side of the retaining shell 9 is connected to a water tank 11 by bolts. A water pump 10 is installed on the top of the water tank 11. The water outlet of the water pump 10 is screwed with a hose 12. The other end of the hose 12 is screwed with a water distribution pipe 4. The water distribution pipe 4 is installed on the left side of the dust cover 1, and an atomizing nozzle 5 is installed at the bottom of the water distribution pipe 4; a transmission rod 21 is installed on the motor shaft of the mining motor 24, and the front end of the transmission rod 21 is welded with an active bevel gear 22. The active bevel gear The wheel 22 is meshed with the driven bevel gear 23; the left end of the driven bevel gear 23 is welded with a rotating shaft 26, the outer side of the rotating shaft 26 is connected to the excavation disc 3 by bolts, and the rotating shaft 26 is rotatably connected to the support pull rod 30; the inside of the conveying trough 6 is rotatably connected to the drive roller 27 near the right end, the inside of the conveying trough 6 is rotatably connected to the drum 28 near the left end, and the conveying trough 6 is rotatably connected to the support rotating rod 29; the belt 8 is nested in the outer side of the drum 28 and the drive roller 27; the hydraulic cylinder 20 is connected to the hydraulic oil supply station 15 through an oil pipe.

[0024] When the outer side of the excavation disc 3 is close to the ground, the excavation motor 24 drives the active bevel gear 22 welded to the front end of the transmission rod 21 to rotate. Since the active bevel gear 22 is meshed with the driven bevel gear 23, the active bevel gear 22 drives the rotating shaft 26 welded to the left end of the driven bevel gear 23 to rotate at high speed, and the rotating shaft 26 drives the excavation disc 3 to rotate at high speed. The J-shaped excavation teeth of the excavation disc 3 perform longitudinal excavation of the ground sand.
