Abstract
The utility model relates to an agricultural machine, which comprises a machine frame, a diesel engine, road wheels, a cam, a belt wheel and a ratchet wheel, wherein, the belt wheel and the cam are arranged and fixed coaxially, the ratchet wheel and the road wheels are arranged and fixed coaxially, and a connecting rod is arranged between the ratchet wheel and the cam. One end of the connecting rod is fixed movably with tooth blocks which can be engaged with the teeth of the ratchet wheel, the other end is fixed with a stopping block which can be butted movably with the cam, and the connecting rod end of the stopping block is provided with a spring which is connected with the machine frame. The utility model has the characteristics of simple structure, small size, light weight, low cost, flexible and convenient operation and use, small turning angle, etc., and is suitable for the tillage and the processing of farmlands.
Description
The utility model relates to a kind of agricultural machinery, is applicable to the ploughing and weeding and the arrangement in farmland.
At present, generally adopt in the rural area to be used as power, drag plough or rake and realize ploughing and weeding and arrangement the farmland by farm cattle or hand tractor etc.Farm cattle need artificial feeding, not only take a lot of work but also time-consuming the cost height.The hand tractor volume is big, and angle is big when turning round, and the edge in farmland is difficult to plough whole arriving, and puts in order so often need artificial supplementation to plough.
The purpose of this utility model is to provide that a kind of volume is little, cost is low, operation, the harvesting and tillage machine of superminiature flexibly easy to use.
Superminiature harvesting and tillage machine of the present utility model, comprise frame, diesel engine, road wheel, cam, belt pulley and ratchet, it is characterized in that: belt pulley installs and fixes with cam is coaxial, road wheel and coaxial ratchet install and fix, be provided with connecting rod between ratchet and the cam, connecting rod one end movable fixing can with the block teeth of the tooth engagement of ratchet, the other end be fixed with can with the block of the movable butt of cam, the connecting-rod head of this block also is provided with the spring that links to each other with frame.
Below in conjunction with drawings and Examples the utility model is illustrated.
Fig. 1 is the utility model structural representation.
By accompanying drawing 1 as seen, the superminiature harvesting and tillage machine of present embodiment, the both sides of its road wheel 3 and road wheel 3 be coaxial to be mounted with a pair of ratchet 4, the both sides of belt pulley 9 and the belt pulley 9 coaxial convex surface ends that are mounted with pair of cams 10, two cams 10 180 degree that should stagger.Be respectively equipped with connecting rod 8 in the frame 1 of hollow between cam 10 and the ratchet 4, an end of connecting rod 8 is hinged with block teeth 5, and these block teeth can mesh with the ratchet of ratchet 3 is movable; The other end of connecting rod 8 is fixed with block (14), this block can with the movable butt of the convex surface end of cam 10.Connecting rod 8 ends of block 14 are fixed with spring 15, and the other end of spring is connected and fixed in the frame 1 of hollow.Diesel engine 2 is fixed on the front end of frame 1, and its output connects with belt pulley 9 by belt 6.
Handrail 11 has been fixedly connected respectively on the axle sleeve of cam 10 axle heads.
The front end of connecting rod 8 is connected with to draw stops 7, draw the control device of stopping 12 to be fixed on the handrail 11, plate dynamic control device 12, controlled draws 7 drivening rods of stopping to lift or put down, make the block teeth 5 of connecting rod 8 ends and the ratchet separate or merge of ratchet 4, thus the walking of control road wheel 3 or stop.
The rear end of frame 1 is connected with the connection plate 13 that drags plough or rake.
The outer rim of road wheel 3 is provided with walking sheet 16.
Its operation principle: power reaches belt pulley 9 through belt 6, reach cam 10 again through camshaft, the convex surface butt block 14 of cam promotes connecting rod 8, the block teeth 5 of connecting rod 8 ends under the effect of self gravitation with the ratchet engagement of ratchet 4, move forward thereby promote road wheel 3.After the convex surface of cam 10 breaks away from block 14, connecting rod 8 travelling backwards under the effect of spring 15, block teeth are skipped the ratchet top backward and are dropped in one teeth groove of back, repeat said process, promote road wheel 3 ceaselessly to reach.
This shows that this superminiature harvesting and tillage machine is simple in structure, volume is little, and is in light weight, and cost is low, operation, easy to use, flexible, and the angle of turning round is little, is highly suitable for the farming and the arrangement in farmland.
