Description

Mini-size tillage machine ridging plough mounting structure

Technical field

The utility model relates to the installation of farming instrument, especially the installation of the ridging plough on the connecting plate between the output casing of mini-size tillage machine use.

Background technology

Agricultural Miniature cultivator used on higher is called for short mini-size tillage machine, and mini-size tillage machine is used for farmland operation, and its operating type mainly contains two kinds of operation and the walking movement operations that rotatablely move.Output rotatablely moves, generally be delivered to the farming instrument through behind the speed change gear by gasoline or diesel engine, speed change gear mainly is made up of casing and transmission parts etc. thereof, the casing upper end is fixed on the mini-size tillage machine, the lower end is an output, extend downwardly into the farming instrument from mini-size tillage machine, the casing output forms cantilever design, for example offers farming tool's power such as rotary blade; Walking movement is the same with vehicle to be to drive the wheel walking, and mini-size tillage machine is pulled the operation of walking of farming instrument.The mini-size tillage machine speed change gear has two groups of front and back usually at least, and above-mentioned cantilever design casing has higher strength and stiffness requirement, and therefore, the front and back casing generally couples together with connecting plate, and connecting plate also is used for installing the farming instrument, the ditching knife etc. of for example earthing up.

With reference to accompanying drawing 1, before mini-size tillage machine has, latter two gearbox body 1,1 ', horizontal output shaft 11 is arranged respectively, 11 ', output shaft 11,11 ' output rotatablely moves, be used for being with farming instruments such as rotary blade, two gearbox bodys 1,1 ' is cantilever design, with vertically coupling together that connecting plate 2 follows away, gain in strength and rigidity, connecting plate 2 also is used for installing farming instruments such as ridging plough, the operation of walking, because mini-size tillage machine and farming instrument claimed structure thereof are simple, cheap, two gearbox bodys 1,1 ' manufactures left-right symmetry with steel plate, casing edge, the left and right sides fastens and connects into integral body with bolt, with reference to accompanying drawing 2, Fig. 3, connecting plate 2 is usually by two

block plates

21,22 usefulness joint pins 23 are welded into integral body, steel plate 21, distance between 22 just equals the wall thickness at casing edge, the left and right sides, be fixed on gearbox body 1 with bolt 12 again, 1 ' left and right edges, because above-mentioned connecting plate 2 intensity own have only been considered longitudinal stress, and joint pin 23 welding has only reasons such as and welding deformation at 2, cause with before, rear box 1,1 ' fitted position is difficult for guaranteeing, defectives such as its working strength is not enough under the farming environment of complexity, because the insufficient strength of connecting plate 2, the farming instrument plough of for example earthing up also can only adopt and disperses stressed branch body structure, with reference to accompanying drawing 1, the ridging plough is by plough baffle plate 31, tool rest 34 is formed, plough baffle plate 31 is welded on the baffle plate mounting blocks 32, be installed in connecting plate 2 central forward positions with bolt 33, tool rest 34 is welded on the tool rest mounting blocks 38, be installed in connecting plate 2 central authorities by the position, back with bolt 36, owing to be dispersed structure, cause the bulk strength of ridging plough own relatively poor so again, shortcoming such as yielding, and assembly process is too much when operation, inconvenient operation.

The utility model content

The purpose of this utility model is: a kind of mini-size tillage machine ridging plough mounting structure is provided, solve the relatively poor problem of ridging plough bulk strength that above-mentioned prior art exists, and assembly process when reducing operation, make easy to operate, simultaneously, simple in structure, cheap.

Mini-size tillage machine ridging plough mounting structure of the present utility model, the connecting plate and the ridging plough that comprise casing, connecting plate is made of left and right sides plate, be installed in the casing edge, the left side of its connecting plate, right panel central authorities in opposite directions stamp out boss face, fit between the boss face and be welded into integral body with plug welding, described ridging plough is by the plough baffle plate, left side tool rest, right tool rest is formed, a left side, right tool rest is integrally welded, the plough baffle plate is welded on a left side, right tool rest the place ahead, a left side, right tool rest steel plate punch forming, the top forms installing handle, is installed on the connecting plate with bolt by installing handle.Form boss by punching press, connect into an integral body with tight card of boss face and plug welding, the boss face periphery has the effect of reinforcement, equal profile construction size, the connection steel plate of condition of equivalent thickness, its intensity increases greatly, and make the connecting plate welding deformation little, be easy to guarantee and the fitted position of front and back casing that the ridging plough is welded into overall structure, the intensity height, adapt to complicated more farming environment, simultaneously, the operation of assembling plough when reducing operation, the convenient use.

The edge that boss face described in the scheme is extended to connecting plate forms installing port, and described tool rest installing handle upper end is clipped in the middle boss face from the installing port both sides, uses bolt.The ridging plough is installed on the boss face, because of two block plates are close to, and the installation strength height, the edge that boss face is extended to connecting plate is in order to be stepped down in the boss edge, to make things convenient for design, manufacturing and the installation of ridging plough.

The utlity model has following advantage: do not change on the basis of prior art and the connected mode mini-size tillage machine casing and profile construction size, form boss face by simple punching press, and connect into an integral body with the tight obedient plug welding of boss face, make the connecting plate welding deformation little, intensity increases greatly, be easy to guarantee fitted position with the front and back casing, adopt integrally-built ridging plough simultaneously, the intensity height, adapt to complicated more farming environment, the operation of assembling plough when also reducing operation, the convenient use.
