Angle b is 17 °～18 °, as shown in figure 3, preferably 17 °.
The helicoid of spiral guide plate 5.4 is that straight edge line holding level rotates the spiral to be formed along bent wire in the present embodiment
Face, bent wire is conical spiral；With reference to shown in Fig. 6, straight edge line length (i.e. the height h) of spiral guide plate is 40～42mm,
The aperture of conical spiral is 170～180 °, the 230～235mm of diameter of conical spiral small end taper seat, conical spiral are big
270～the 275mm of diameter of end taper seat and the taper seat inclination angle of conical spiral are identical with the round table surface inclination angle that round platform sieves main body；
Meanwhile, the spiral outward flange of spiral guide plate 5.4 extends one along bent wire perpendicular to helicoid to be used to be arranged on round platform sieve
The right angle flange 5.8 of the gripper shoe 5.64 of frame 5.6.
Because spiral guide plate 5.4 plays push effect to material, material feed quantity is generally 0.3～0.4kg/s, and in sieve
Material bed thickness on face, no more than 40mm, is to ensure that spiral guide plate 5.4 is pushed completely, therefore, its spiral guide plate 5.4
Height h elect 40～42mm as.
In the present embodiment, the quantity of spiral guide plate is 2～3, can be increased and decreased according to material feed quantity, two spirally-guideds
Pitch S between plate 5.4 is 120～140mm, and pitch is relevant with material feed quantity, and pitch is bigger, pushes ability stronger.
The above-mentioned secondary roller formula cleaning plant for Brassica campestris L combining is mountable to Brassica campestris L joint and receives after being completed
Obtain on machine, hydraulic drive motor 1 accesses the hydraulic system that Brassica campestris L combined harvester is carried.After startup, round platform sieves main body 5.5 from liquid
Pressure drive motor 1 direction sees and rotates counterclockwise, seed Jing after Cyclone separating cleaning system is tentatively cleaned and miscellaneous remaining by feeding trough 4
Jing spouts 3.3 feed, and are entered by round platform sieve main body 5.5 small end face in the presence of feeding auger seam 5.7, in spirally-guided
To round platform sieve main body large end face movement under plate 5.4 is pushed and gravity flow of the material on compass screen surface is inclined is acted on.In the process, seed
Permeable screen cloth falls into lower house seed collecting chamber 3.5, is snapped down to discharge port 3.15 along the base plate 3.2 of seed collecting chamber 3.5 and completes
Seed is collected；Then continue to be glided along compass screen surface more than miscellaneous, from the round platform sieve large end face of main body 5.5 miscellaneous remaining discharge room 3.9 is discharged into, arranging
Careless plate seam 5.2 is expelled to field under acting on by straw outlet 3.16, completes whole secondary watering and separation procedure.
Secondary roller formula cleaning plant for Brassica campestris L combining of the present utility model is with cleaning equipped with cyclonic separation
The Brassica campestris L combined harvester of system is used cooperatively, easy to disassemble using hydraulic driving mode, it is easy to changed, keep in repair and is maintained；This reality
It is remaining with miscellaneous with the new separable seed Jing after Cyclone separating cleaning system is tentatively cleaned, grain cleaning rate requirement can be met,
Cyclonic separation cleaning loss percentage can be reduced again, improve the adaptability of Cyclone separating cleaning system.
