Description
Technical field
The utility model relates to agricultural mechanical field, is specifically related to a kind of crawler type rice harvester balance adjustment mechanism.
Background technology
In grain harvesting field, have crawler type and rubber-tyred in grain header miscellaneous, crawler type is compared to rubber-tyred grain header, and its handling capacity is better, has pivot turn ability, in recent years, very popular.
At hilly regions in south China, the rice field of rice cultivation is narrow and small, and shape is changeable, and Rice Cropping is mostly in the paddy field of long-term ponding, very difficult when gathering in, and the crawler type grain header occurred in recent years still shows not too adapt to the operation of paddy field, one of them reason is: the situation of paddy field is changeable, crawler type grain header is in different paddy fields during operation, the degree of depth of sinking is different, keep anterior-posterior balance while reaping part can not carry out angular adjustment easily, make the operating efficiency of grain header unstable, reliability is affected.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of crawler type rice harvester balance adjustment mechanism, to solve the problem of existing crawler-type harvester balance adjustment poor performance.
The technical scheme adopted for realizing the purpose of this utility model is: a kind of crawler type rice harvester balance adjustment mechanism, it is characterized in that, comprise chassis bearing frame, activity adjustment frame, described activity adjustment frame is slidably arranged in the top of chassis bearing frame, and the upper surface of described activity adjustment frame is hinged is provided with hydraulic jack.
Further, the structure realizing described chassis bearing frame and described activity adjustment frame relative sliding is: described chassis bearing frame and described activity adjustment frame are respectively equipped with the channel-section steel that mutual left-hand thread coordinates.
Further, described chassis bearing frame comprises crossbeam, longeron and carriage, and described two longerons be arranged in parallel, described crossbeam is arranged between two longerons, described crossbeam is vertical with longeron and be fixedly connected with, and described carriage is arranged on above crossbeam, is fixedly connected with crossbeam.
Further, lead screw pair relative sliding is passed through between described chassis bearing frame, activity adjustment frame.
Further, described activity adjustment frame is slidably arranged on the carriage of described chassis bearing frame.
Further, described lead screw pair comprises leading screw and feed screw nut, and described feed screw nut is fixedly installed on activity adjustment frame, and described screw turns is arranged on the bearing frame of chassis, and described leading screw is connected with screw nut driven.
Further, the transmission direction of described lead screw pair is parallel with the direction of chassis bearing frame, activity adjustment frame relative sliding.
The beneficial effects of the utility model:
A kind of crawler type rice harvester balance adjustment mechanism that the utility model provides, chassis bearing frame is provided with the channel-section steel coordinated with the mutual left-hand thread of top movable adjusting bracket, relative sliding between the activity adjustment frame realizing bottom chassis bearing frame and top, realizes the slide anteroposterior of activity adjustment frame relative chassis bearing frame simple and stable; In addition, above activity adjustment frame, being hinged with hydraulic jack, when needing the height regulating reaping part, regulating the flexible of hydraulic jack; The utility model is very applicable on crawler type rice harvester, one, crawler type rice harvester does not have enough spaces and volume to go to install complicated Automatic Balance Regulation system, two, this balance adjustment mechanism does not almost have the general structure of grain header increases unnecessary weight again, the crawler type rice harvester of operation in paddy field is very necessary to the control of its overall weight, otherwise, larger weight can cause grain header to sink, affect efficiency, traditional wheel is turned and changes axle into and turn.
Accompanying drawing explanation
Fig. 1 is the structural representation of the crawler type rice harvester balance adjustment mechanism that the utility model provides;
Fig. 2 is the A-A cutaway view of the crawler type rice harvester balance adjustment mechanism that the utility model provides.
Embodiment
Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.
Fig. 1 shows a kind of crawler type rice harvester balance adjustment mechanism that the utility model provides, comprise chassis bearing frame 19, activity adjustment frame 20, activity adjustment frame 20 is slidably arranged in the top of chassis bearing frame 19, and the upper surface of activity adjustment frame 20 is hinged is provided with hydraulic jack 16.
In the present embodiment, chassis portion comprises chassis bearing frame 19, chassis bearing frame 19 forms the support to whole rice harvester, chassis bearing frame 19 comprises two crossbeams 2 and 14, two longerons 1 and 12, carriages 21, two longerons 1 and 12 be arranged in parallel, and two crossbeams 2 and 14 are arranged between two longerons, and crossbeam is vertical with longeron and be fixedly connected with, carriage 21 lies on crossbeam 2 and 14, and carriage 21 is fixedly connected with crossbeam.At the driving wheel 3 that one end of two longerons 1 and 12 is crawler type rice harvester, driving wheel 3 is connected by driving shaft 4, and this is with power transmission shaft 4 not load-bearing in the present embodiment.In the below along two longerons, be provided with carrying wheel 13, crawler belt 10 wraps up driving wheel 3 and carrying wheel 13; These components above-mentioned constitute the chassis of whole crawler type rice harvester, its role is to load-bearing and walking.
Composition graphs 1 and Fig. 2, the carriage 21 arranged above crossbeam 2 and 14 also has two longerons 5 and 9, longeron 5 is identical with 12 with longeron 1 with the layout trend of 9, and longeron 5 and 9 adopts channel-section steel, and the profile of activity adjustment frame 20 is similar to carriage 21, comprise horizontal frame 15 and 7, vertical frame 6 and 8, wherein vertical frame 6 and 8 is also the channel-section steel adopted, vertical frame 6 coordinates with longeron 9 between two with longeron 5, vertical frame 8, and the mode of cooperation is exactly the given shape left-hand thread between two utilizing channel-section steel, and formation is slidably matched; On the horizontal frame 15 of activity adjustment frame 20, be provided with hydraulic jack 16, hydraulic jack 16 is hinged with horizontal frame 15, can rotate; Leading screw 17 is provided with between the horizontal frame 15 and carriage 21 of activity adjustment frame 20, horizontal frame 15 is fixed with feed screw nut 22, coordinate between leading screw 17 with feed screw nut 22, the trend of leading screw 17 moves towards identical with longeron 5 and 9, further, the other end of leading screw rotates setting on carriage 23, and turned position is an axle sleeve 23, axle sleeve 23 limits the play of leading screw 17, makes it to promote activity adjustment frame 20 and slides.
