Can find out that this bidirectional locking mechanism is evenly assemblied in four ends of knife rest by Fig. 2 and Fig. 3, be coupled together by front and back cylinder, combine and form grass mower height-regulating mechanism of the present invention, and can find out for high degree of symmetry structure.
Technical scheme for a better understanding of the present invention, describes embodiment provided by the invention in detail below in conjunction with accompanying drawing.When needs increase cutting-height, first, the rear section of grass mower is regulated: i.e. accompanying drawing 1-3 intermediate roll rib 3,13, wedge magnetic slide block 17,23,15,24, adjustment screw 4,5,14,25; Cylinder rib 3,13 bottom is connected with back roll 16 two axial ends respectively; Make wedge magnetic slide block 23,24 throw off cylinder rib by regulating adjustment screw 5,25 simultaneously simultaneously, make in adjustment process cylinder rib 3,13 simultaneously phase cutter setting frame 11 move downward, adjustment screw 4,14 while of reaching after cutting-height requirement, wedge magnetic slide block 17,15 and cylinder rib 3,13 are fitted tightly again, namely realizes bidirectional locking; Secondly, the front part of grass mower is regulated: i.e. accompanying drawing 1-3 intermediate roll rib 8,22, wedge magnetic slide block 18,29,20,26, adjustment screw 10,9,21,27; Cylinder rib 8,22 bottom is connected with front roll 19 two axial ends respectively; Make wedge magnetic slide block 29,26 throw off cylinder rib by regulating adjustment screw 9,27 simultaneously simultaneously, make in adjustment process cylinder rib 8,22 simultaneously phase cutter setting frame 11 move downward, adjustment screw 10,21 while of reaching after cutting-height requirement, wedge magnetic slide block 18,20 and cylinder rib 8,22 are fitted tightly again, namely realizes bidirectional locking; Finally, make the bottom keeping parallelism of front roll 19 and back roll 16 phase cutter setting frame 11, namely ensure that and higher cut careless precision.
Fig. 2 and Fig. 3 is respectively the top and bottom perspective views of hob type grass mower body portion, can find out that the present invention is for being arranged symmetrically with by top and bottom perspective views.Symmetrical structure is convenient to realize interchangeability and batch production, cuts down finished cost.
Fig. 5 is the basic views of cylinder rib of the present invention, can find out that cylinder rib of the present invention is straight flange by front view Fig. 5 a, and another side is that the wedge magnetic slide block of symmetrical wedge shape limit and Fig. 6 realizes fitting tightly, and realizes bidirectional locking.The width of T-slot is equal with the Breadth Maximum of cylinder rib.
Fig. 6 is the basic views of wedge magnetic slide block, by just waiting end view Fig. 6 d can find out that wedge magnetic slide block of the present invention has a blind hole, coordinating, and realize magnetic absorption state with adjustment screw in Fig. 1.By unclamping adjustment screw, wedge magnetic slide block is adsorbed in adjustment screw when ensure that and heighten, thus the cylinder rib making wedge magnetic slide block and magnetic relatively weak departs from, and (cylinder rib does not produce Main Function to the suction of magnet.Namely time in order to regulate, wedge magnetic slide block moves with adjustment screw.）。Further utilize the magnetic of wedge magnetic slide block to make in mechanism of the present invention, to be positioned at tightly being adsorbed on knife rest of bottom to be unlikely to come off.
The foregoing is only preferred embodiments of the present invention.Therefore scope of the present invention can not be limited with this.Namely the equivalence change done with the present patent application the scope of the claims and description all should belong to the scope of the claims of the present invention with modification.
Unaccomplished matter of the present invention is known technology.
