Specific embodiment
Noun of locality "inner", "outside" used in the utility model embodiment are for this body structure of napper.
The one side of the utility model embodiment provides a kind of napper for concrete prefabricated board, referring to Fig. 1, drawing
Hair machine includes two spaced support frames 10, shaft 20, multiple connectors 30, main shaft 40, multiple spacers 60, multiple groups plucking knife
Piece 50, two stop parts 41 and driving mechanism 70；The both ends of shaft 20 are rotatablely connected with corresponding support frame 10 respectively；Multiple companies
One end of fitting 30 is fixedly connected with shaft 20, such as is welded, and multiple connectors 30 are arranged along the axially spaced-apart of shaft 20, often
One end of the separate shaft 20 of a connection piece 30 is formed with axis hole (not shown)；Main shaft 40 is arranged in the axis hole of every a connection piece 30
It is interior；Every group of plucking blade 50 includes multiple plucking blades 50, wears one group of plucking on the main shaft 40 between adjacent two connector 30
Blade 50.
The napper of the utility model embodiment is arranged in the axis hole of connector 30 due to the both ends of main shaft 40,
Greatly improve the installation reliability at 50 cooperation of main shaft 40 and plucking blade；Furthermore main shaft 40 is arranged in multiple connectors 30
In strengthen the stiffness and strength of 40 structure of main shaft.
Multiple connectors 30 can be integrated formed structure with shaft 20, be also possible to integrally welded structure.This reality
It applies in example, connector 30 is in rectangular cylinder structure, and one end of cylindricality column structure and shaft 20 are welded.Rectangular cylinder structure resists
Curved modulus is big, has preferable anti-bending strength, to be capable of the weight of reliably cantilever support plucking blade 50 and main shaft 40.
Shaft 20 can be an integrally formed axis, be also possible to be welded by multistage axis.Main shaft 40 can be
Whole is in cylindrical type, is also possible to be welded by the different part in multistage section.Referring to Fig. 1, in the present embodiment, main shaft 40
Cylindrical section 202 including rectangular cylinder section 201 and positioned at 201 both ends of rectangular cylinder section.One end of connector 30 and rectangular column
Body section 201 is welded, and since the end of connector 30 is rectangular, connector 30 and rectangular cylinder section 201 are plane contact, is not necessarily to
Especially processing contact surface can be welded reliably, and production process, improving production efficiency so can be greatly simplified.
In order to reinforce the bonding strength between rectangular cylinder section 201 and cylindrical section 202, in the present embodiment, it is outside to be located at axis
Two connectors 30 of side are folded between corresponding rectangular cylinder section 201 and cylindrical section 202, and rectangular cylinder section 201 is welded in
The axial side of connector 30, cylindrical section 202 are welded in the axial other side of connector 30, since the two sides of connector 30 are in
Plane, therefore bonding area can be increased, reinforce weld strength, promotes connection reliability.
For the ease of the connection of shaft 20 and support frame 10, Fig. 3 and Fig. 4 are please referred to, napper includes two short axles 22, adjusts
Screw 23 and axle sleeve 21.Two support frames 10 have been respectively formed on through hole (not shown), axle sleeve 21 be embedded in through hole and with branch
Support 10 is welded to connect；One end of short axle 22 is formed with stop lug 210, and short axle 22 is inserted into cylindrical section 202 after passing through axle sleeve 21
Interior, stop lug 210 is connected to the outside of axle sleeve 21.Further, adjustment hole is formed on the peripheral wall of cylindrical section 202, and (figure is not
Show), adjust screw 23 and pass through adjustment hole and adjust the bottom end of screw 23 and be connected to the outer surface of short axle 22, in this way, short axle 22 with
Shaft 20 can rotate synchronously.
Referring to Fig. 2, spacer 60 is sheathed on main shaft 40, a spacer 60 is set between every adjacent two pluckings blade 50, i.e.,
Spacer 60 and plucking blade 50 are arranged alternately, and spacer 60 can guarantee the spacing between adjacent two pluckings blade 50, prevent plucking
50 axial float of blade.In the present embodiment, spacer 60 uses polyurethane material, can effectively reduce the weight of the receiving of main shaft 40,
The stress condition that improves main shaft 40, simultaneously as polyurethane stock material is cheaper than steel, therefore, using polyurethane material every
Set 60 can also greatly reduce production cost, economical and practical.
To prevent 40 axial float of main shaft, above-mentioned stop part 41, stop part are provided on outermost two connector 30
41 are located at the side away from plucking blade 50 of connector 30.In the present embodiment, referring to Fig. 1, stop part 41 is in flat cover shape,
Stop part 41 covers at around the axis hole of connector 30, and stop part 41 is connect with 30 screw of connector.
Fig. 1 and Fig. 2 are please referred to, driving mechanism 70 and shaft 20 are drivingly connected with the rotation of drive shaft 20.Shaft 20 rotates
The height and position of changeable main shaft 40, therefore the terrain clearance of blade can be adjusted, it can be according to the thickness of concrete prefabricated board
Degree adjusts the terrain clearance of plucking blade 50, promotes the force stability of plucking blade 50, enables plucking blade 50 mixed
The groove that essentially identical depth is pulled out on solidifying soil prefabricated board, guarantees plucking quality.
The assembly method of the utility model embodiment napper includes the following steps:
S1: the assembling of support frame 10, shaft 20 and connector 30 is finished, that is to say, that first by support frame 10, shaft 20
And connector 30 forms an entirety.
S2: the first end of main shaft 40 is passed through to the axis hole of first connector 30 along the axial one end of shaft 20；It needs
Bright, if main shaft 40 interts since the axial first end of shaft 20, first connector 30 is located at the of shaft 20
First of one end；The main shaft 40 interts since the axial second end of shaft 20, then first connector 30 is located at shaft
Second of 20 second end.After main shaft 40 passes through the axis hole of first connector 30, the end of the first end of main shaft 40 is located at
Between first connector 30 and adjacent next connector 30.
S3: one group of plucking blade 50 is sheathed on main shaft 40, wherein worn between adjacent two pluckings blade 50 one every
Set 60；In the step, plucking blade 50 and spacer 60 are singly alternately socketed on main shaft 40, plucking blade 50 and spacer
60 quantity control can fill up the main shaft 40 between two neighboring connector 30, the number between adjacent two connector 30
A plucking blade 50 is one group of plucking blade 50.
S4: the first end of main shaft 40 is continued to move axially along shaft 20, so that the first end of main shaft 40 is across next
The axis hole of connector 30 repeats step S3；That is, often having interted the plucking blade between adjacent two connector 30
50 and spacer 60 after, main shaft 40 enters between next adjacent two connector 30, hereafter continues interspersed plucking blade 50 and spacer
60。
S5: circulation step S4, until the first end of main shaft 40 passes through the axis hole of the last one connector 30；
S6: backstop is installed respectively on the outside of the axis hole of first connector 30 and on the outside of the axis hole of the last one connector 30
Part 41.
