Description
Technical field
The present invention relates to rotary digging machine barrel brills.
Background technique
Spiral digging machine is a kind of construction machinery of pore-forming operation in suitable building foundation engineering.
Spiral digging machine cooperates rotary digging machine barrel to bore, and is suitable for dry type (short spiral) or wet type (rotary bucket) and rock stratum (rock core drill)
Pore-forming operation is mainly used for urban construction, highway bridge, industry and civil buildings, diaphram wall, water conservancy, antiseepage slope protection etc.
Foundation construction.
It includes barrel, the toothholder being mounted on barrel and the pick being mounted on toothholder, use process that rotary digging machine barrel, which bores,
In, rock surface largely wears and fails in pick, toothholder contact hole, and pick can not be supported to work and be broken, cause it can not
Continue to promote, finally have to stop working, the pick toothholder bored to cylinder is replaced.
In the prior art, since barrel, the tooth seat structure being mounted on barrel design unreasonable, and toothholder and barrel
It is not connected firmly, replaces difficult disadvantage, affect the use that entire rotary digging machine barrel bores.
Summary of the invention
The purpose of the present invention is to disadvantages mentioned above, provide one kind and are connected firmly, are durable, replacing easy rotary digging
Machine barrel bores --- a kind of rotary digging machine barrel brill of clamping.
The used following technical scheme of the present invention: a kind of rotary digging machine barrel brill of clamping, it includes barrel, is mounted on barrel
On toothholder and the pick that is mounted on toothholder, the barrel is cirque structure, is mounted in Spiral digging machine below barrel
On mounting base, above with multiple toothholders installation position；
There is the mounting hole of pick, the pick is mounted in mounting hole on the toothholder；
It is characterized in that:
The installation position is a notch, and the notch has side portion and bottom, and side portion and bottom are formed
There is protrusion, raised two sides are concave stations, and protrusion and concave station Formation cross-section are convex shapes among " u "-shaped notch, side portion and bottom
Section；Below the toothholder and side has the structure of cooperation notch, and there are also the pin holes run through between toothholder and barrel, and
Pin hole connection toothholder and barrel are passed through with elastic cylindrical pin.
Further speaking, two sides of the toothholder are wider than the side of toothholder.
Further speaking, the mounting hole turns forward setting.
Further speaking, the notch turns forward setting, and inclined angle is 45 °.
The beneficial effects of the present invention are: such rotary digging machine barrel drilling tool is connected firmly, is durable, replacement is readily excellent
Point；
The toothholder side is wider than the side for being mounted on barrel position, also has the advantages that more durable；
The mounting hole turns forward setting, and the notch turns forward setting, and inclined angle is 45 °, is also had
Have the advantages that more durable.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model fission.
Fig. 2 is the overlooking structure diagram of this pick.
Fig. 3 is the A partial schematic diagram in Fig. 2.
Wherein: 1, barrel 2, toothholder 3, pick 4, mounting base 5, installation position 6, mounting hole 7, protrusion
8, pin hole 9, elastic cylindrical pin 10, toothholder side are wider than the part 11 of barrel side, recess 12, fin.
The angle that angle beta-notch that α-mounting hole turns forward turns forward.
Specific embodiment
The present invention will be further described below with reference to the drawings.
As shown in Figure 1, 2, 3, a kind of clamping rotary digging machine barrel bore, it include barrel 1, the toothholder being mounted on barrel 2, with
And it is mounted on the pick 3 on toothholder, the barrel is cirque structure, the mounting base being mounted on Spiral digging machine below barrel
4, above with the installation position 5 of multiple toothholders；
There is the mounting hole 6 of pick, the pick is mounted in mounting hole on the toothholder；
It is characterized in that:
The installation position is a notch, and the notch has side portion and bottom, and side portion and bottom are formed
There is protrusion 7, raised two sides are concave stations, and protrusion and concave station Formation cross-section are convex shapes among " u "-shaped notch, side portion and bottom
Section；Below the toothholder and side has the structure of cooperation notch, i.e., has recess 11 and fin 12, recess on toothholder
It is the section of concave shape with fin Formation cross-section, the section of convex shape and the section of concave shape are the structures of cooperation, are also run through
Pin hole 8 between toothholder and barrel, and pin hole connection toothholder and barrel are passed through with elastic cylindrical pin 9.
When toothholder abrasion, the elastic cylindrical pin between the toothholder and barrel of damage is removed；Unload the toothholder of damage, then
New toothholder is accurately aligned with the installation position of barrel, the recess 11 and fin 12 of protrusion and concave station the cooperation toothholder of barrel,
Plug together connection, the F in Fig. 1 is installation direction, after the two is positioned with elastic cylindrical pin, complete installation process.
Further speaking, the toothholder side is wider than the side for being mounted on barrel position, and 10 be that toothholder side is wide in figure
In the part of barrel side, as shown in Figure 2,3.It installs so stronger.
Further speaking, the mounting hole turns forward setting.As shown in Figure 1, the angle to turn forward is α.
Further speaking, the notch turns forward setting, and inclined angle is 45 °.As shown in Figure 1, notch is forward
Inclined angle beta.
It is above-mentioned although specific embodiments of the present invention are described with reference to the accompanying drawings, but it is not practical new to this
The limitation of type protection scope, those skilled in the art should understand that, based on the technical solution of the present invention, ability
Field technique personnel do not need to make the creative labor the various modifications or changes that can be made still in the protection model of the utility model
Within enclosing.
