To control, number is enclosed through reasonable settings and screw pitch may make the spiral of helicla flute 21 to tend towards stability, main shaft 2 is avoided to rotate
When generate larger axial resistance, in actual setting, when enclose number determine after, increase screw pitch enable to helicla flute 21 more to level off to
Straight line reduces circle number and helicla flute 21 is enabled to more to level off to straight line after screw pitch determines；In the present embodiment, we can be with
Provide one group of design parameter: circle number is 0.3 circle, and screw pitch 280, main shaft outer diameter is 40, and unit does not provide herein.
The twister 4 includes columned shell 41 and helical spring 42, and the connecting rod 132 is cut with scissors with 41 phase of shell
It connects, one end of the helical spring 42 is fixed in the shell 41, and the other end of the helical spring 42 is fixed nested
The through-hole passed through for the main shaft 2 is offered on the end of the main shaft 2, the corresponding shell 41；The helical spring
42 corresponding helixes are conical spiral, and the cross section of the helical spring 42 is rectangle, and the length of the rectangle is greater than described
The screw pitch of the corresponding helix of helical spring 42, as shown in fig. 7, the rectangle indicated in figure is the cross section of helical spring 42,
I.e. helical spring 42 is to be scanned based on the rectangle by the path of the helix in Fig. 7；This kind of helical spring 42
It is arranged so that a kind of its structure for forming plate, projection in the axial direction forms the structure of similar clockwork spring, so that it has
There is the accumulation of energy in circumferential direction, while it also has the accumulation of energy of common spring in the axial direction, there is helical spring 42 circumferential
With the energy-storage buffering of axial both direction, and the length of cross section be greater than its screw pitch so that the throwing in the radial direction of helical spring 42
Shadow generates overlapping area (such as Fig. 4 can be seen that generation overlapping), and then traditional cylindrical spring is avoided to generate mutually collision in compression
The phenomenon that dislocation.
Further, the sieve nest 3 includes columned sieve 31 and is fixedly installed consolidating at 31 both ends of sieve
Fixed board 32, the fixed plate 32 are nested on the main shaft 2, several clamping screws 321, institute are provided in the fixed plate 32
It states and offers feeding port 322 in fixed plate 32, cover board is installed on feeding port 322；The half of the sieve 31 offers several
A equally distributed first sieve pore, the other half of the sieve 32 offer several equally distributed second sieve pores, and described
The internal diameter of one sieve pore is less than the internal diameter of second sieve pore；Due to the design feature of helicla flute 21, the parameter of helicla flute 21 is controlled,
It can get the different rotational angle range of main shaft 2, using the design feature of helicla flute 21, the range that main shaft 2 rotates is not exceeded
180 degree, therefore two different sieve pores can be at least set on sieve 31, multistage screening is carried out, replacement sieve is avoided
31 trouble substantially increases the efficiency of screening.
Embodiment 2: on the basis of embodiment 1, limit base 12, institute are further fixedly arranged on the further bottom plate 1
The limiting slot offered on limit base 12 for the connecting rod 132 sliding is stated, in embodiment 1, connecting rod 132 circumferentially rotates (i.e.
Rotation) it is limited by drive disk 131, it is capable of the circumferential direction of further limiting rod 132 by limit base 12 in the present embodiment
Rotation.
Further, in embodiment 1 and embodiment 2, linear bearing, the linear axis are provided on the bearing block 6
It holds and is nested on the main shaft 2, to realize rotation and the linear motion of main shaft 2.
In use, first adjusting the position of sieve 31, sieve pore to be used is needed by the selection of clamping screw 321, so
Material is placed by feeding port 322 afterwards, screening work can be carried out by finally starting motor 13；During the work time, connecting rod 132 drives
Dynamic main shaft 2 moves along a straight line, and the helicla flute 21 on main shaft 2 drives main shaft 2 to circumferentially rotate, and then generates two kinds of motion modes, most
Make sieve 31 generate the screening in screening and circumferential direction in axial direction eventually, forms the screening in multiple directions, and then greatly improve
Screening efficiency, while the corresponding compression and circumferential direction generated in axial direction in the movement of sieve 31 of the helical spring 42 in twister 4
On folding and unfolding, generate elastic buffer variation, further promote the movement of sieve 31, while to produce between connecting rod 132 and main shaft 2
Raw buffer strip, improves the connectivity of the two.
The present invention is using the helicla flute on main shaft, so that main shaft can generate on axial and circumferential driven by the motor
Two kinds of movements finally make sieve generate the screening in screening and circumferential direction in axial direction, form the screening in multiple directions, in turn
Greatly improve screening efficiency；Helical spring in the twister corresponding compression generated in axial direction and week in screen movement simultaneously
Upward folding and unfolding generates elastic buffer variation, further promotes the movement of sieve, while to generate between connecting rod and main shaft slow
Band is rushed, the connectivity of the two is improved.
Obviously, various changes and modifications can be made to the invention without departing from essence of the invention by those skilled in the art
Mind and range.In this way, if these modifications and changes of the present invention belongs to the range of the claims in the present invention and its equivalent technologies
Within, then the present invention is also intended to include these modifications and variations.
