Need to put together in the soil being scattered during backfill of planting trees, then fill out in tree well, soil is shed too far, causes to backfill time consuming.
The content of the invention
The utility model in view of the shortcomings of the prior art, develops a kind of pit-picker, the soil concentration that the pit-picker is spun out
In tree well surrounding, convenient backfill, greatly save manually, improve planting speed；Avoid man-machine injury caused by sandstone splashes.
The utility model solve technical problem technical scheme be：On the one hand, the embodiment provides one kind to dig
Hole machine, including motor, mounting bracket, spiral dig knife, and motor is arranged on mounting bracket, and spiral digs knife and is arranged on below mounting bracket, spiral shell
The output shaft of the rotating shaft connection motor of rotary digging knife, mounting bracket set operating handle or connection external impetus equipment, the pit-picker
Also include limitation cover, the cylindrical shape for both ends open is covered in limitation, and the barrel dliameter for limiting cover is more than the external diameter that spiral digs knife.On mounting bracket
Operating handle is set, pit excavation work, mounting bracket connection external impetus equipment, such as hand push can be completed by man-hour manually hand-held operating handle
Car, motor vehicles, then it can complete pit excavation work by operating external impetus equipment.Before digging pit, limitation cover is first placed into pre- digging
On the ground for cheating position, then operate pit-picker and dig pit.
As optimization, the limitation cover is internally provided with centring ring, and centring ring and limitation cover are concentric, and the internal diameter of centring ring is big
The external diameter of knife is dug in spiral.
As optimization, the pit-picker also includes protective cover, and protective cover is the cylindrical shape of both ends open, and protective cover is arranged on
The top of cover is limited, the internal diameter of protective cover is more than the external diameter of limitation cover, spring is provided between protective cover and limitation cover.
As optimization, the upper end of the protective cover is provided with protective plate, and protective plate is provided centrally with digging knife entrance.
As optimization, the limitation cover, protective cover, protective plate are made using web plate or closed plate.
The effect provided in the content of the invention is only the effect of embodiment, rather than whole effects that invention is all, above-mentioned
Technical scheme has the following advantages that or beneficial effect：
1. by setting limitation cover, the soil that can spin out pit-picker concentrates on tree well surrounding, convenient backfill, saved significantly
Save manually, improved planting speed；Man-machine injury caused by sandstone splashes is avoided simultaneously.
2. by setting centring ring, the restriction that cutter position is dug to spiral is realized, spiral is dug the operating position of knife and is located at
The center of cover is limited, the soil dug out can be evenly distributed in limitation cover.
3. by setting protective cover, with the increase for depth of digging pit, protective cover contacts with mounting bracket, and is gradually depressed,
All the time isolate the splashing path of sandstone, the sandstone that pit-picker is spun out is not splashed, avoid to man-machine injury.
4. being provided with protective plate by the upper end in protective cover, the possibility that sandstone splashes from top is prevented, has preferably protected
Man-machine safety is hindered.
