Abstract
The utility model discloses a height-adjusting locking mechanism of a rotary tiller, comprising a height-adjusting handle, a height adjuster base, an elastic element, a positioning sleeve and an adjusting rod. The height-adjusting handle is arranged below an armrest and connected with a flexible stay wire; the height adjuster base is arranged above an angle square rack; the other end of the flexible stay wire is also connected with a stopper pin by a Z-shaped head arranged in the height adjuster base; the elastic element props and pushes the stopper pin; the positioning sleeve is fixed at the rear side of the angle square rack; and the adjusting rod slides up and down along the positioning sleeve, is connected with a wheel shaft and is provided with a plurality of locating slots arranged in-line along the vertical direction. The height of a tilling knife is adjusted by splicing the stopper pin and a positioning groove. The mechanism has simple structure, simple and convenient operation, time and labor saving and high mechanization degree.
Description
Technical field
The utility model relates to a kind of rotary tillage tractor-ploughing knife up degree governor motion, especially a kind of heightening and locking mechanism of rotavator.
Background technology
Rotovator is when operation, according to cultivated native degree of depth requirement, need control and adjust the high and low position of ploughing cutter at any time, therefore traditional rotovator all has cultivated knife up degree governor motion, but be to adopt semi-automatic the heightening of pin-and-hole formula mostly, must earlier kill engine when heightening at every turn, take away safety pin, extract and heighten pin, to heighten pin again interts in the hole of appointment, its complicated operating process wastes time and energy very much, does not also have the comparatively ideal measure of heightening so far.
Summary of the invention
Goal of the invention of the present utility model is to overcome the defective of prior art and a kind of easy and simple to handle, time saving and energy saving heightening and locking mechanism of rotavator is provided.
According to the foregoing invention purpose, the utility model is achieved through the following technical solutions:
A kind of heightening and locking mechanism of rotavator, it comprises handrail and angle square frame on the cultivated machine transmission case body of the trip of being fixed on, and be fixed on adjusting rod on the wheel shaft, it is characterized in that described handrail below is provided with heightens handle, this is heightened handle and connects flexible bowden cable, and the other end of flexible wiring passes protective plate and enters the Height-adjusting device seat that is located at angle square frame top and connect gear pin by the elastic component pushing tow; Described angle square frame rear side is connected with positioning sleeve, and it is interior along the upper and lower slippage of positioning sleeve that described adjusting rod is located at positioning sleeve, and is provided with a plurality of locating slots that " one " font is arranged that vertically are in a side; Described gear pin realizes ploughing the adjusting of knife up degree through arbitrary locating slot locking latch of positioning sleeve and adjusting rod.
Described handrail is provided with the clamp of a plurality of supporting flexible bowden cables.
Described Height-adjusting device seat and the releasable connection of angle square frame, Height-adjusting device seat top are provided with the Height-adjusting device lid.
Described Height-adjusting device seat is provided with the backguy seat at flexible bowden cable end of incoming cables sidewall.
Described flexible bowden cable connects the gear pin by the Z prefix.
Described Height-adjusting device seat is provided with the fairlead of gear pin slippage guiding.
Compared with prior art, the utility model realizes that through linkage component the locking latch of gear pin and adjusting rod locating slot realizes ploughing knife up Du Gaojie by the handle of heightening that manipulation is located at the handrail below, and this height-regulating mechanism is simple in structure, and is easy and simple to handle, time saving and energy saving, the mechanization degree height.
Description of drawings
Fig. 1 is the mounting structure schematic diagram of the utility model on rotovator.
Fig. 2 is the sectional structure enlarged drawing at Fig. 1 F place.
Embodiment
By above-mentioned accompanying drawing the utility model embodiment is described in detail again below.
Shown in Fig. 1～2,1-handrail, 2-heighten handle, 3-flexible bowden cable, 4-clamp, 5-adjusting rod, 6-angle square frame, 7-positioning sleeve, 8-Z prefix, 9-elastic component, 10-Height-adjusting device lid, 11-backguy seat, 12-Height-adjusting device seat, 13-fairlead, 14-gear pin, 15-locating slot among the figure.
Heightening and locking mechanism of rotavator, this mechanism comprise be located at handrail 1 below heighten handle 2, heightening handle is extending type, flexible bowden cable 3 is connected with it, flexible bowden cable extends below handrail simultaneously, on total length, be provided with 2 supporting clamps 4 that prevent that backguy is sagging, the flexible bowden cable lower end is passed the rotovator protective plate and is connected backguy seat 11, this backguy seat is installed in end of incoming cables one side of Height-adjusting device seat 12, the Height-adjusting device seat is located at angle square frame 6 tops, by the detachable connection of screw, the gear pin 14 that the flexible bowden cable rearmost end connects by elastic component 9 spring push through Z prefix 8, Height-adjusting device seat top connects Height-adjusting device lid 10, makes spring, the Z prefix, parts such as gear pin are built-in, and flexible bowden cable is by steel wire rope system.
Be fixed on an angle square frame 6 is arranged on the rotovator transmission case body, described angle square frame rear side welding stationary positioned cover 7, the adjusting rod 5 that connects wheel shaft is located in the positioning sleeve 7 can upper and lower slippage along positioning sleeve, vertically be provided with the locating slot 15 that is horizontal " U " type of " one " font arrangement of a plurality of being because of adjusting rod, the locating slot opening is aimed at the gear pin, and " one " font arrangement of described being promptly is arranged on the differing heights position of same area.The gear pin 14 that nose shape and locating slot match serves as that guiding and the arbitrary locating slot 15 that passes the adjusting rod 5 in positioning sleeve 7 and the positioning sleeve plug locking and realize ploughing the knife up degree and regulate with fairlead 13.
When the cultivated cutter tilling depth requirement of needs adjusting is highly regulated ploughing cutter, pull the moving handle 2 of heightening, flexible bowden cable 3 was pulled Height-adjusting device seat 12 interior springs was compressed this moment, gear pin 14 is pulled the locating slot 15 that breaks away from adjusting rod, this moment, handrail 1 descended the rotovator casing by pressing, angle square frame 6 descends synchronously, then drive positioning sleeve 7 and gear pin 14 moves down, when the gear pin is displaced downwardly to the requirement height, when in a single day the gear pin aims at another locating slot, promptly spring release can act under pushing tow gear pin insert the locating slot of new aligning once more and automatically lock, the process of heightening finishes; The process of oppositely heightening is lifted, and handrail gets final product.
