Abstract
The present invention discloses the durable drill head of a kind of well cellar for storing things formula hole making drill, it includes the connecting rod (1) that end is taper, the two panels cambered blade (2) of make-up is had dislocation in the upper connection of connecting rod (1), offer rotating shaft connecting hole (3) in the upper end of connecting rod (1), described cambered blade (2) is to be formed after sharping at long limit 1/2 2/3 on the face of cylinder taking 1/4 1/3.The connected mode of described connecting rod (1) and cambered blade (2) is for welding.The present invention the most existing core drilling head has more robust, to increase drill head service life, can transplant aperture, hole according to Jing Jiao and be adjusted size, can reduce the feature of production cost, safety and reliability.
Description
Technical field
The present invention relates to the durable drill head of a kind of well cellar for storing things formula hole making drill, belong to agriculture tool of production field.
Background technology
What flue-cured tobacco well cellar for storing things formula seedling transplantation technique had become as that Guizhou and other parts save tobacco planting industry promotes mainly technology,
In several years promoted, this transplanting method has embodied many merits, is approved by numerous smokers, existing for improving the formula cultivation of well cellar for storing things
Plant the perforate speed in hole, the existing perforate well cellar for storing things formula hole making drill using backpack more, the structure of the well cellar for storing things formula hole making drill of backpack
Existing a lot of patents, such as Patent No. 201520178720, disclosed in entitled " a kind of backpack Nicotiana tabacum L. well cellar for storing things machine card punch "
" a kind of backpack Nicotiana tabacum L. well cellar for storing things machine card punch, including drill head, described drill head top connection molding device, described molding device
Being joined with bolts disk above, fixed disc is arranged above with spacing in the rows chi and support bar, in the other end of described support bar on
Portion is provided with annular operation handle and throttle grip, and throttle grip is connected with electromotor, and the end of support bar connects flexible axle, described soft
Axle one end is connected with power assembly, and the other end is connected with drill head in the middle of support bar." above-mentioned well cellar for storing things formula card punch is
It is well positioned to meet perforate task, but in use, because existing drill head is welded by steel pipe and tapered cap, so exists
Use after a period of time and there is worn out phenomenon, there is use time shorter problem.
Summary of the invention
Basis is the most practical to solve the technical problem that the durable drill head being to provide well cellar for storing things formula hole making drill, can overcome existing skill
The deficiency of art.
The technical scheme is that kind of a durable drill head for well cellar for storing things formula hole making drill, it includes the connection that end is taper
Bar, connects the two panels cambered blade having dislocation make-up in connecting rod, offers rotating shaft connecting hole in the upper end of connecting rod.
The durable drill head of above-mentioned well cellar for storing things formula hole making drill is that described cambered blade is to take the face of cylinder of 1/4-1/3
Formed after sharping at the 1/2-2/3 on long limit.
The durable drill head of aforesaid well cellar for storing things formula hole making drill is, described connecting rod is weldering with the connected mode of cambered blade
Connect.
Prior art compares, and the present invention connects the two panels cambered blade having dislocation make-up in connecting rod, in connecting rod
Upper end offers rotating shaft connecting hole, and such solid steel structure the most existing core drilling head is more durable, can increase brill
The service life of hole head；The two panels cambered blade of dislocation make-up can be transplanted aperture, hole according to Jing Jiao and is adjusted size, it is ensured that open
Bore dia；Cambered blade be the face of cylinder taking 1/4-1/3 at the 1/2-2/3 on long limit after sharping formed, such one hollow
Pipe just can process 6 pieces of cambered blades, makes three drill head, thus can reduce production cost further；Connecting rod and curved knife
The connected mode of sheet uses welding, and the mode of welding is relatively reliable relative to the mode that bolt is fixed (is bolted to boring procedure
In there will be bolt looseness or screw bolt abrasion, easily fly out in high-speed rotation and hurt sb.'s feelings).
Accompanying drawing explanation
The attachment structure schematic diagram of Fig. 1 present invention.
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
Embodiment 1. as depicted in figs. 1 and 2, end be the connecting rod 1 of taper be to be intercepted 30cm by six-edged steel, one end is beaten
Wear into taper, the other end is opened screwed hole 3 and is constituted, and screwed hole 3 can mate with the drive link of existing well cellar for storing things formula hole making drill, then even
Being welded with the two panels cambered blade 2 of two pieces of dislocation make-ups on extension bar 1, cambered blade 2 is that the face of cylinder taking 1/4-1/3 is in long limit
Formed after sharping at 1/2-2/3.
In use, the drill head with this drill head replacement existing well cellar for storing things formula hole making drill is the most permissible, the user in field
Method is identical with existing well cellar for storing things formula hole making drill using method.
Claims (3)
1. the durable drill head of a well cellar for storing things formula hole making drill, it is characterised in that: it includes the connecting rod (1) that end is taper,
