Embodiment
Below in conjunction with accompanying drawing 1-6 and embodiment, the utility model is described in further detail, but they are not to restriction of the present utility model:
embodiment 1
In the reciprocating reaping apparatus of the sine mechanism of band spring pre-tightening as shown in the figure: the strip cutter 2 for cutting leaf vegetables is horizontally disposed, sine mechanism 1 connects strip cutter 2 one end for driving strip cutter 2, is connected the other end of strip cutter 2 with the spring adjustment mechanism 4 coordinating sine mechanism 1 to work.The strip cutter 2 that the utility model adopts is saw blade preferably.
In described sine mechanism 1: the wheel shaft 141 of flywheel 14 is coaxially fixedly connected with by the output shaft of shaft coupling 12 with motor 11, on flywheel 14 end face, eccentric setting one trundle 142(offset is determined as required); Described back-up block 15 is positioned at a guide rail slidably, and (direction of extension of guide rail is parallel with the length direction of saw blade; Guide rail is omitted in figure) on, back-up block 15 is also manufactured with the oval pinhole 151 coordinated with described trundle 142.Obviously, the major axis direction of extension of oval pinhole 151 should be vertical with the direction of extension of guide rail.
In described spring adjustment mechanism 4: two spring stacks 47 fixing (vertically fixing) are on spring-support plate 41, pressing plate 46 to be set on two spring stacks 47 by two through holes opening system and to be arranged in parallel with spring-support plate 41, two springs 44 are set on two spring stacks 47 respectively and between spring-support plate 41 and pressing plate 46, two adjusting nuts 45 are tightened on the top (top of spring stack is manufactured with external screw thread) of two spring stacks 47 respectively and subject spring 44 pressure by pressing plate 46; Moving lever 43 and two spring stacks 47 are arranged in parallel, its rear end (Fig. 5 is left end) is connected in pressing plate 46(figure after passing over the straight hole on spring-support plate 41 again: the boss that diameter is greater than spring-support plate 41 straight hole is made in moving lever 43 rear end, to bear the pulling force between moving lever 43 and spring-support plate 41); The front end of moving lever 43 is connected to the other end (moving lever 43 axis and strip cutter 2 length direction are arranged vertically substantially) of strip cutter 2 by fixed block 3.By regulate fixed block 3, can ensure saw blade planar horizontal arrange and sawtooth outwardly, be beneficial to horizontal resection vegetables.
As preferably, between moving lever 43 and spring-support plate 41, clamp linear bearing 42.
In addition, motor 11 by the L shaped plate of support set 13 upper surface be fixed on grain header frame side (Fig. 6 display be right side, spring-support plate 41 is fixed on the opposite side (Fig. 6 display is left side) of grain header frame, and blade level extends to the left and right sides of frame, and sawtooth is arranged outward.
During work, motor 11 drives flywheel 14, and the trundle 142 on flywheel driven 14 makes back-up block 15 do reciprocating linear motion along guide rail with the groove fit on back-up block 15, thus drives saw blade to do straight reciprocating motion by back-up block 15; The fixed block 3 of the saw blade other end, moving lever 43 and pressing plate 46 carry out straight reciprocating motion simultaneously accordingly.
When flywheel 14 drives back-up block 15(saw blade) turn right motion time (Fig. 2 be saw blade turn right motion extreme point), spring 44 is compressed into the shortest (visible in figure: to be opened a segment distance between adjusting nut 45 and pressing plate 46), has put aside maximum potential; When flywheel 14 drives back-up block 15 toward left movement, the potential energy that spring 44 dependence is put aside pulls saw blade, and toward left movement, (Fig. 2 is the extreme point of saw blade toward left movement; Consume the potential energy of major part savings) simultaneously.Move and so forth, what ensure that saw blade makes horizontal reciprocating movement, thus obtains the shuttling movement needed for Cut vegetables.
Fig. 6 shows the installation site of the utility model on leaf vegetables grain header.
In a word, the foregoing is only preferred embodiment of the present utility model, the equalization change that all scopes applied for a patent according to the utility model are done and modification, all should belong to covering scope of the present utility model.
