Abstract
The invention provides an automatic regulating device for the deflection angle of a harrow assembly of scarification equipment. The automatic regulating device comprises a machine frame, a regulating lead screw, a nut sliding block, a lower pressing plate, a coupler, a hydraulic motor and harrow assembly beams. The machine frame is composed of cross beams, upper connecting plates, lower connecting plates, boundary beams, a motor support and a middle beam. Each cross beam and the corresponding boundary beam are fixedly connected through the corresponding upper connecting plate and the corresponding lower connecting plate. The distance A between the end face of each boundary beam and the inner side face of the corresponding cross beam is larger than the width of each harrow assembly beam. The middle beam is installed in the middle of the machine frame, and the motor support is fixed to the middle beam. The nut sliding block and the lower pressing plate are symmetrically installed on the upper surface and the lower surface of the middle beam respectively. The inner end of each harrow assembly beam is installed between the nut sliding block and the lower pressing plate, and the inner end of each harrow assembly beam, the nut sliding block and the lower pressing plate are fixed together through connecting pieces. The outer end of each harrow assembly beam is located between the corresponding upper connecting plate and the corresponding lower connecting plate. One end of the regulating lead screw is connected with the nut sliding block through threads. The other end of the regulating lead screw is connected with the hydraulic motor through the coupler. The hydraulic motor is fixed to the motor support. The deflection angle of the harrow assembly can be regulated by controlling the hydraulic motor to rotate.

Embodiment
Below in conjunction with embodiment and accompanying drawing, the invention will be further described.
In Fig. 1 and Fig. 2, rake group drift angle automatic regulating apparatus comprises frame 1, adjusting screw 2, nut slider 3, lower platen 4, shaft coupling 5, hydraulic motor 6, rake group beam 7.Frame 1(is as shown in Figure 3 and Figure 4) formed by crossbeam 8, upper junction plate 9, lower connecting plate 10, side bar 11, motor bearing 12 and central sill 13; Upper junction plate 9 and lower connecting plate 10 are fixed together crossbeam 8 and side bar 11, and the distance A of the medial surface of side bar 11 tip to face distance crossbeams 8 is greater than the width of rake group beam 7, and central sill 13 is arranged on frame 1 middle part, and motor bearing 12 is fixed on central sill 13; Nut slider 3 and lower platen 4 symmetries be arranged on central sill 13 above and below; The inner of rake group beam 7 is arranged between nut slider 3 and lower platen 4, is also fixed together with bolt, nut or other connector, and outer end is between upper junction plate 9 and lower connecting plate 10; Adjusting screw 2 one end are connected with nut slider 3 by screw thread, one end by shaft coupling 5 be connected with hydraulic motor 6; Hydraulic motor 6 is fixed on motor bearing 12.
One U-shaped groove is arranged at nut slider (3) bottom, and the width of the width B of U-shaped groove and central sill (13) is matched in clearance.
Hydraulic motor (6) is low speed hydraulic motor, and its rotating speed is no more than 400r/min.Rake group beam (7) is rectangular steel tube or rectangular steel pipe.Crossbeam (8), side bar (11) and central sill (13) are rectangular steel tube.
The course of work of the present invention is: in the time of needs adjustment rake group drift angle, first control hydraulic system rises built on stilts by frame together with the workpiece on it, then control hydraulic system drives hydraulic motor rotation, meanwhile hydraulic motor drives adjusting screw rotation by shaft coupling, because adjusting screw and nut slider are with being threaded togather, adjusting screw drives nut slider to move on central sill thus, drive rake group beam inner mobile thereupon, because rake group beam outer end is stuck in upper junction plate, lower connecting plate, in the space that side bar end face and crossbeam side form, its position is substantially motionless, therefore the movement of rake group beam the inner has just changed the drift angle of rake group beam.In the time adjusting to suitable angle, control hydraulic system stops operating hydraulic motor, has so far completed the adjustment process of rake group drift angle.
