Abstract
The utility model relates to a pit drilling device, in particular to a rotary pit drilling device which comprises a rotating shaft, a fixed head, a scraping plate, a bushing and a crank, wherein one end of the rotating shaft is fixedly connected with a drill bit, the other end of the rotating shaft is connected with the crank, the scraping plate having a spiral structure is fixedly connected on the rotating shaft at the end connected with the drill bit, and the bushing is sheathed on the rotating shaft connected above the scraping plate. The rotary pit drilling device can drive the whole machine to rotate under the driving of manpower or a machine by utilizing self rotating power or the power of the machine so as to complete the whole operational function of drilling a deep pool fully automatically. The deep pool drilling and pit drilling effect is as good as that achieved by manual work, the efficiency is high, the cost is low, the weight is light, and the operation is simple.
Description
Technical field
The utility model relates to a kind of brill pit device, particularly a kind of revolving brill pit device.
-background technology
Along with the development of mechanization, special brill hole excavator has been saved labour cost, has reduced labour intensity, and has improved efficiency.But excavate in some brill holes on a small scale, use special brill hole excavator operation, it is very high and uneconomical that cost will seem, therefore hand diggings that adopt more, and hand digging efficient is low, labour intensity is big.One Chinese patent application number is that 200620010555.5 utility model discloses a kind of " rod-pit drilling rod " this utility model and comprises hollow drill; Be installed in the hollow boring bit of hollow drill bottom; The spirality scraping blade that is connected with the hollow boring bit blade is installed on the hollow drill hypomere outer wall; On the outer wall of hollow drill, have two vertical grooves; On the hollow drill bottom interior wall above the hollow boring bit, be provided with horizontal narrow annular groove, this narrow annular groove is communicated with vertical groove bottom wherein, reaches in the vertical groove that is communicated with it at narrow annular groove the pulley wire saw cutting device is installed; The hollow drill inwall of narrow annular groove top is provided with horizontal wide annular groove, and this wide annular groove is communicated with another vertical groove bottom, reaches in the vertical groove that is communicated with it at wide annular groove manual enclasp device is installed; Top at hollow drill is equipped with power input shaft, is provided with guard shield along two vertical grooves.This rod-pit drilling rod can implement to bore fast the hole to setting the place, and position, bar hole, the degree of depth can both be able to guarantee.But this jackrod structure is complicated, and cost of production is too high.
Summary of the invention
The purpose of the utility model is intended to overcome the defective of prior art, provides a kind of simple in structure, and cost of production is low, and bores hole efficient height, the rotary brill pit device that labour intensity is low.
The described rotary brill pit device of the utility model; Constitute by power transmission shaft, drill bit, scraping blade, sleeve pipe and crank; One end of power transmission shaft is fixedly connected with drill bit, and the other end is connected with crank, on the power transmission shaft that connects drill bit one end, is fixedly connected with scraping blade; Scraping blade is a sped structure, on the power transmission shaft above the connection scraping blade, is socketed with sleeve pipe.
Be socketed with grip cover on the described power transmission shaft, grip cover is fixed on the top of power transmission shaft through alignment pin.The effect of CONTEN STEEL OVAL NECK TRACK BOLTS is the length of regulating power transmission shaft.The operator of being convenient to different heights can use, according to the length that requires the free adjustment power transmission shaft of oneself.
The described rotary brill pit device of the utility model, it can produce from the body rotation, thereby blade is rotated under the driving of manpower or machine power, lets rotating blades dig the soil that will beat the place in pool come, and accomplishes the whole pool work of beating.
Beat the method for using of pool device: the hand-tight grip of shaking hands, another has been held crank, inserts drill bit in the soil that will dig a pit, hole, etc., shakes crank, and at this moment, scraping blade also will rotate by identical direction.Because scraping blade is screw type, the direction of its spiral rotation and earth in the opposite direction, like this, the scraping blade of rotation will outwards squeeze away earth.Thereby accomplish the hole work of boring.Slip joint casing on power transmission shaft can guarantee in boring the hole process, and the operator of different heights can be according to the length of demand free adjustment power transmission shaft of oneself.The rotary brill pit device of the utility model, especially it can be under the driving of manpower or machine, utilizes the power of self Power of Spin or machine, drives the rotation of entire machine, can all accomplish the whole operational function of beating the pool automatically.And beat the effect of boring the hole in the pool with artificial beat that the pool brill cheats the same good, efficient is high, cost is low, in light weight, simple to operate.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure, 1-crank, 2-grip cover, 3-alignment pin, 4-power transmission shaft, 5-scraping blade, 6-CONTEN STEEL OVAL NECK TRACK BOLTS, 7-sleeve pipe, 8-drill bit.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation, but be not limited to embodiment.
Embodiment 1
As shown in Figure 1, the described rotary brill pit device of the utility model is made up of power transmission shaft 4, drill bit 8, scraping blade 5, sleeve pipe 7 and crank 1; One end of power transmission shaft 4 is fixedly connected with drill bit 8, and the other end is connected with crank 1, is socketed with grip cover 2 on the described power transmission shaft; Grip cover 2 is fixed on the top of power transmission shaft 4 through alignment pin 3; On the power transmission shaft 4 that connects drill bit 8 one ends, be fixedly connected with scraping blade 5, scraping blade 5 is a sped structure, on the power transmission shaft 4 above the connection scraping blade 5, is socketed with sleeve pipe 7; CONTEN STEEL OVAL NECK TRACK BOLTS 6 is connected with sleeve pipe 7, and the length that is used to regulate power transmission shaft satisfies operator's demand.
Embodiment 2
The utility model is achieved in that a 1cm is thick, power transmission shaft 4, the one end sharpenings of long 80cm are drill bit 8, sets up plural scraping blade 5 at an end of point; An other end of power transmission shaft 4 is set up movable crank 1; The effect of crank 1 is the height that is free to regulate power transmission shaft 4, unscrews CONTEN STEEL OVAL NECK TRACK BOLTS 6, according to requirement for height, the stretching power transmission shaft 4 of oneself; After having regulated, tighten CONTEN STEEL OVAL NECK TRACK BOLTS 6 and get final product.Scraping blade 5 connects after the power transmission shafts 4 will be according to the bending direction rotation crank 1 of blade, and the spiral direction of rotation of scraping blade 5 be counterclockwise, is accustomed to rotating counterclockwise crank 1, and the spiral direction of rotation of scraping blade 5 then is counterclockwise.
