Embodiment
As shown in Figure 1 and Figure 2, green onion kind planting management reaping machine of the present invention comprises hauling machine 1, is connected the harvest machinery on the hauling machine 1, and hauling machine 1 can adopt common hand tractor, also can adopt agricultural machinery such as tractor with small four wheels.Described harvest machinery comprises main frame 2, the unsteady suspension frame 3 that is connected on the main frame 2, and main frame 2 and suspension frame 3 all are the frame structures that are welded by some crossbeams and longeron, are provided with secondary row travelling wheel 10 in the rear end of main frame 2.The front end of main frame 2 is connected on the hauling machine 1 by hitch, and the rear end of main frame 2 connects transverse axis 4 by bearing, and the two ends of transverse axis 4 are installed in the bearing, and this bearing is installed in respectively on two side girders of main frame 2 rear ends by bearing block.Fixedly connected control stick 5 and connecting lever 7 on the transverse axis 4, control stick 5 is all vertical with transverse axis 4 with connecting lever 7, be provided with normal locking mechanism between control stick 5 and the main frame 2, connecting lever 7 is hinged to the rear end of suspension frame 3, and the connected mode of connecting lever 7 and suspension frame 3 can have multiple, for example, can be as shown in Figure 1, in the rear end of suspension frame 3 the connection hangers is set, an end of connecting rod 21 is hinged on and connects on the hangers, and the other end of connecting rod 21 is hinged on the connecting lever 7.Also can adopt other articulated manner between connecting lever 7 and the suspension frame 3.
Front end at suspension frame 3 is provided with bearing pin 8, the fixedly connected axis pin base 9 of the front end of main frame 2, the slotted hole that has vertical setting on the described axis pin base 9, bearing pin 8 are inserted in this slotted hole, and the front end of suspension frame 3 is in transmission connection by the power take-off of eccentric wheel transmission mechanism and hauling machine 1; The both sides of suspension frame 3 are fixedly connected with the ploughshare frame 11 of downward extension, and the lower end of ploughshare frame 11 is equipped with ploughshare 12.Certainly, use in order to adapt to different occasions, ploughshare frame 11 can be designed to telescopic structure.
The effect of above-mentioned normal locking mechanism is that the device that can adjust angle between control stick 5 and the main frame 2 and be fixed is set, this normal locking mechanism comprises the toothed disc 6 that is fixedly connected on the main frame 2, is fixedly connected on the spring(-supported) mount 13 on the control stick 5, the center of circle of described toothed disc 6 is positioned on the axis of transverse axis 4, the card of toothed disc 6 is vertical with transverse axis 4, has teeth groove 61 on the circumference of toothed disc 6; One side of toothed disc 6 is welded on the longeron of main frame 2, and transverse axis 4 interts in the center of circle of toothed disc 6.Described spring(-supported) mount 13 is the pipe shape, locking bar 14 is inserted in the spring(-supported) mount, and locking bar 14 is parallel with control stick 5, is provided with return spring 15 between locking bar 14 and the spring(-supported) mount 13, the rear end of locking bar 14 has pull bar 16 and slide block, and described slide block is inserted into the chute that is arranged on the control stick 5.
