The utility model comprises a frame, a power machine, a transmission, a controlling device and a working part, and is characterized in that matched tenon and tenon slot are arranged respectively at the connecting port of the driving shaft and the rotation shaft of the working part, and a clamp nut with inner spigot which can slide and rotate on the axle is arranged on the connecting port of one of the shafts, and external threads which can match the threads of the clamp nut are provided on the connecting port of the other shaft. The utility model is an improved product with advantages of simple structure, reliable connection, convenient replacement of working parts, and preventing axial movement.

Description

Change multipurpose small cultivator easily

Technical field

The utility model relates to a kind of tillage machinery, particularly a kind of multipurpose small cultivator easily that changes.

Background technology

Existing multipurpose small cultivator, its workpiece driving shaft all are to adopt key to be connected with the workpiece turning cylinder, in order to prevent axial motion, must be with a plurality of securing members with the diaxon axial restraint, so complex structure is changed dismounting and must be used specific purpose tool, it is hard to tackle to change dismounting.

Summary of the invention

At above problem, the purpose of this utility model provide a kind of simple in structure, connect reliable, no axial motion, the easy-to-disassemble and assemble multipurpose small cultivator easily that changes of workpiece replacing.

A kind of multipurpose small cultivator easily that changes, comprise frame, engine, transmission device, actuation means and workpiece, it is characterized in that: be respectively equipped with tenon and the tongue-and-groove that matches at workpiece driving shaft and workpiece turning cylinder link, establish the clamp nut that has inner stopper that the rotation of sliding is housed on the connectivity port of an axle therein on axle, on the connectivity port of another root axle, be provided with external screw thread with the clamp nut threads engaged.Just: on the link of workpiece driving shaft and workpiece turning cylinder, be provided with tenon or tongue-and-groove, on the link of workpiece turning cylinder and workpiece driving shaft, be provided with tongue-and-groove or the tenon that matches, and on workpiece driving shaft or workpiece turning cylinder, establish the clamp nut that has inner stopper that the rotation of sliding is housed on axle, on the port of the link of workpiece turning cylinder or workpiece driving shaft, be provided with external screw thread with the clamp nut threads engaged.

The utility model connects workpiece driving shaft and workpiece turning cylinder by tongue-and-groove, and utilize and to establish the clamp nut that has inner stopper that rotates that can on this, slide that is mounted in it on the axle and be rotated with, so it is simple in structure, connect reliable, no axial motion, workpiece changes easily, is a kind of replacing dismounting upgrading products very easily.

Embodiment

Describe in detail below in conjunction with drawings and Examples:

It among the figure a kind of multipurpose small cultivator easily that changes of the present utility model, mainly comprise frame, engine, transmission device, actuation means and workpiece 6, its main points are: workpiece driving shaft 1 adopts tenon 3 to be connected with tongue-and-groove 4 with workpiece turning cylinder 7, and establish the clamp nut that has inner stopper 2 that the rotation of sliding is housed on the axle therein on axle, on the connectivity port of another root axle, be provided with external screw thread with clamp nut 2 threads engaged.

Tenon 3 among the figure is arranged on the workpiece driving shaft 1, tongue-and-groove 4 is arranged on the workpiece turning cylinder 7, the clamp nut 2 that has an inner stopper utilizes alignment pin 5 to slide to establish rotatably and is contained on the workpiece driving shaft 1, is arranged on the port of workpiece turning cylinder 7 and workpiece driving shaft 1 link with the external screw thread of clamp nut 2 threads engaged.Obviously, tenon 3 and tongue-and-groove 4 also can be separately positioned on workpiece turning cylinder 7 and the workpiece driving shaft 1, the clamp nut 2 that has an inner stopper also can utilize alignment pin 5 to slide to establish rotatably and be contained on the workpiece turning cylinder 7, also can be arranged on the port of workpiece driving shaft 1 and workpiece turning cylinder 7 links with the external screw thread of clamp nut 2 threads engaged; Also can otherwise make the clamp nut 2 that has inner stopper slide to establish rotatably is contained on workpiece driving shaft 1 or the workpiece turning cylinder 7.Workpiece driving shaft 1 is arranged on the output of transmission device.

During dismantlement work parts 6, as long as unclamp clamp nut 2, the workpiece turning cylinder 7 and the termination of workpiece driving shaft 1 link are withdrawed from from the link end of workpiece driving shaft 1, the other end of workpiece driving shaft 1 is extracted out from the axle bed of other end just whole workpiece can be taken off then; When peace changes jobs parts, as long as the other end with workpiece turning cylinder 7 inserts in the axle bed of other end earlier, in the tongue-and-groove 4 that on workpiece driving shaft 1 link, is provided with of tenon 3 that workpiece turning cylinder 7 links are provided with or tongue-and-groove 4 sleeves or on the tenon 3, screw clamp nut 2 then and get final product then.Obviously, the utility model has not only been realized the farming function conversion by changeing whole workpiece 6, as the workpiece 6 that loosens the soil of Fig. 4 is just changed and can be loosened the soil, the mowing workpiece 6 of Fig. 5 is just changed and can be mowed, the rake grass workpiece 6 of Fig. 6 is just changed to be harrowed grass; And make the replacing dismounting very convenient.
