Get deeply stuck in when the mellow soils such as marshy land carry out trench digging operation or driving wheel skids, thus improve work
Industry efficiency.
Utility model content
In view of this, the purpose of this utility model is to overcome defect of the prior art, it is provided that a kind of trench digging digs
Hole device, this trench digging device is provided with helical blade, during trench digging, utilizes helical blade to produce
Raw propulsive force, is prevented effectively from trench digging machine and sends out when the mellow soils such as marshy land carry out trench digging operation
Life is got deeply stuck in or driving wheel skids, thus improves operating efficiency.
Trench digging device of the present utility model, including tubular tool rest, the helical-blade that is fixed on described tubular tool rest
Sheet and trench digging blade;
Further, described trench digging blade is radially fixed to tubular tool rest rear end face, described helical blade
Extand rearward to be connected with trench digging blade;
Further, described trench digging blade cuboid strip structure;
Further, described trench digging blade is more than helical blade along tubular cutter along the height of tubular tool rest radial direction
Seat height radially;
Further, described tubular tool rest is hollow cylinder, the welding of described Rotary tillage blade and tubular end surface of knife holder,
Helical blade is welded in tubular tool rest periphery;
Further, described tubular tool rest is provided with polygon installing hole vertically.
The beneficial effects of the utility model are: trench digging device of the present utility model, and trench digging device is arranged
There is helical blade, during trench digging, utilize the propulsive force that helical blade produces, be prevented effectively from trench digging and dig
Hole machine gets deeply stuck in when the mellow soils such as marshy land carry out trench digging operation or driving wheel skids, this trench digging
Digging machine may utilize baby tractor or the rotary cultivator with traction wheel drives, and trench digging device is multiple and divides
It is not arranged in multiple drive shaft be arrangeding in parallel, controls the rotation direction of drive shaft, make trench digging blade
In the middle of trench digging machine, stir soil to both sides, when the traction wheel of tractor or rotary cultivator rotates, complete
Ditching operation, when traction wheel wheel stops operating, and when making trench digging device original place rotate, trench digging device can
Carry out digging pit operation.
Accompanying drawing explanation
With embodiment, the utility model is further described below in conjunction with the accompanying drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
Detailed description of the invention
Fig. 1 is structural representation of the present utility model, as it can be seen, the trench digging device of the present embodiment,
The helical blade 2 including tubular tool rest 1, being fixed on described tubular tool rest 1 and trench digging blade 3;Open
It is provided with helical blade 2 on ditch Digging machine, during trench digging, utilizes what helical blade 2 produced to push away
Enter power, be prevented effectively from trench digging machine and get deeply stuck in when the mellow soils such as marshy land carry out trench digging operation
Or driving wheel skids, this trench digging device may utilize baby tractor or the rotary cultivator with traction wheel drives,
Trench digging device is multiple and is separately mounted in multiple drive shaft be arrangeding in parallel, controls the rotation of drive shaft
Direction, makes trench digging blade 3 stir soil to both sides in the middle of trench digging machine, when tractor or rotary tillage
When the traction wheel of machine rotates, complete ditching operation, when traction wheel wheel stops operating, make trench digging device original place
During rotation, trench digging device can be carried out digging pit operation.
In the present embodiment, described trench digging blade 3 is radially fixed to tubular tool rest 1 rear end face, described
Helical blade 2 extands rearward to be connected with trench digging blade 3, makes trench digging blade 3 simultaneously and tubular
Tool rest 1 and helical blade 2 connect, and therefore, the bonding strength of trench digging blade 3 is higher, it is possible to effectively
Avoiding blade in operation process fracture occur, the length of helical blade 2 is longer simultaneously so that it is in operation
The propulsive force produced in journey is bigger.
In the present embodiment, described trench digging blade 3 is cuboid strip structure, rectangular-shaped cutter hub tool
Having higher structural strength, trench digging blade 3 usually can be hard by soil medium stone etc. in operation process
The impact of thing, therefore, uses rectangular-shaped cutter hub to be avoided that it fractures in operation process.
In the present embodiment, described trench digging blade 3 is more than helical blade along the height of tubular tool rest 1 radial direction
2 along tubular tool rest 1 height radially, it is ensured that trench digging blade 3 can with the degree of depth of soil effect, from
And guarantee that ditching depth reaches preset value.
In the present embodiment, described tubular tool rest 1 is hollow cylinder, the welding of described Rotary tillage blade and tubular tool rest
1 end face, helical blade 2 is welded in tubular tool rest 1 periphery;Hollow cylinder tool rest 1 is used effectively to subtract
The deadweight of light cutter, uses and is welded and fixed trench digging blade 3 and helical blade 2, and its connection reliability is relatively
Height, is conducive to saving manufacturing cost simultaneously.
In the present embodiment, described tubular tool rest 1 is provided with polygon installing hole vertically, the installation of the present embodiment
Hole is regular hexagon hole, and the tool driving shaft of rotary cultivator also has the shaft part of regular hexagonal section, by this axle
Section coordinates with installing hole thus drives this rotary cultivator attachment to rotate.
Finally illustrate, above example only in order to the technical solution of the utility model to be described and unrestricted,
Although being described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art should
Work as understanding, the technical solution of the utility model can be modified or equivalent, without deviating from this reality
By objective and the scope of new technique scheme, it all should be contained in the middle of right of the present utility model.
