Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, to help understanding content of the present utility model.
As shown in Figure 1-Figure 3, a kind of foot-operated drilling machine, comprise column 2, be connected to the frame 1 of column 2 upper end, be connected to the base 3 of column 2 lower end, be contained in drilling rod 4 bottom described frame 1 with the operating desk 5 be positioned on described base 3, also comprise the foot drive device be connected with described drilling rod 4 by transmission mechanism 20;
Described foot drive device comprises pedal 6, extension spring 19, crank 7, connecting rod 8, rocking bar 9, ratchet 10, ratchet 11, torsion spring (not shown), first A-frame 12, second A-frame, installing rack 13, rotating shaft 14, first sprocket wheel 15, chain 18 and the second sprocket wheel 16, described crank 7 one end is arranged on described installing rack 13 by jointed shaft, described crank 7 other end and described connecting rod 8 one end hinged, described connecting rod 8 other end and described rocking bar 9 one end hinged, described rocking bar 9 other end and described ratchet 10 root hinged, described rotating shaft 14 two ends are connected on described first A-frame 12 and the second A-frame by bearing block and bearing, described ratchet 11 is packed in described rotating shaft 14, described one end is connected on described first A-frame 12, the other end is connected in described rotating shaft 14, described first sprocket wheel 15 is packed in described rotating shaft 14, described second sprocket wheel 16 is packed on the power transmission shaft 17 that is connected with described transmission mechanism 20, described chain 18 is contained on described first sprocket wheel 15 and the second sprocket wheel 16, described extension spring 19 one end is connected with the jointed shaft of described crank 7 and connecting rod 8, the other end is connected with described pedal 6.
The operation principle of this device is: be original state shown in reference Fig. 2, Fig. 2.Step on pedal 6, pedal 6 pulls extension spring 19, extension spring 19 pulls crank 7 to rotate counterclockwise, connecting rod 8 also corresponding actions, rocking bar 9 produces the trend of moving to the direction away from ratchet 11, rocking bar 9 drives ratchet 10 to promote ratchet 11 and rotates counterclockwise certain angle, and the torsion of torsion spring is smaller, so ratchet 10 can promote the torsion rotation that ratchet 11 overcomes torsion spring.When ratchet 11 rotates, rotating shaft 14 is rotated, and the first sprocket wheel 15 rotates, and the second sprocket wheel 16 rotates, and drives transmission mechanism 20 transmission, drives drilling rod 4 once to hole to operating desk 5 feeding.Unclamp pin, deformation is replied in extension spring, and pedal 6 lifts reply ortho states, and ortho states replied by crank 7 and connecting rod 8, torsion spring replys ortho states, and drive ratchet 11 to rotate clockwise go back to home position, the first sprocket wheel 15 reverses, second sprocket wheel 16 reverses, and transmission mechanism 20 reverse drive, drilling rod 4 lifts reply ortho states.Once hole by having operated above.This device adopts foot-operated mode to drive boring, laborsaving, improves working (machining) efficiency, reduces labor intensity.This unit efficiency is made to be more than 2 times of former hand gear.
Too unexpected during in order to prevent from stepping on, cause damage to chain 18 and sprocket wheel and device entirety, preferably below described pedal 6, air cushion is housed, to play cushioning effect, protection chain 18, sprocket wheel and device are overall.
When pedal 6 is placed directly on the ground; stepping on pedal 6 for a long time also can make pin tired out; tired out in order to what alleviate that pin tramples for a long time; on the lower surface of described pedal 6, be preferably provided with the rubber column of circular array arrangement; play cushioning effect; protection foot, prevents from trampling for a long time and causes foot tired out or injured.
