Description

Micro-cultivator clutch

Affiliated technical field the utility model relates to a kind of arrangement of clutch, relates in particular to a kind of micro-cultivator clutch of being made up of handle, bulb and gear frame.

Background technology Chinese patent CN100405888C discloses a kind of like this clutching device of mini-size tillage machine, its design feature is: comprise engine, engine output shaft, the driving wheel that is connected with engine output shaft, belt and driven pulley, comprise that also drive unit is connected with engine, being used to drive engine moves, engine drives driving wheel and moves, change the centre distance between main merit wheel and the driven pulley, make belt be in tensioning or relaxed state, drive unit also connects a clutch backguy and is sleeved on the outer clutch backguy outer liner tube of clutch backguy, when the clutch backguy when pulled, the reaction force acts that clutch backguy outer liner tube is subjected to the clutch backguy makes drive unit drive engine and moves on drive unit; Device drives and comprises that fixed block is connected with clutch backguy one end, regulating bolt is connected with an end of clutch backguy outer liner tube, moved to the fixed block direction by the thrust of clutch backguy outer liner tube, adjustable nut is connected with engine with the adjusting bolt respectively, move with the mobile promotion engine of regulating bolt, spring is connected between adjustable nut and the fixed block, with moving of engine, spring is compressed, and produce the restoring force that the driving engine oppositely moves, therefore, this structure is comparatively complicated, Operation and maintenance are inconvenient, especially are not suitable for staying the elderly in poverty-stricken area and mountain area because of the strong labour power goes out to do manual work, the womankind manipulates.

The summary of the invention the purpose of this utility model provides a kind of simple in structure, and Operation and maintenance are micro-cultivator clutch easily.

For achieving the above object, the utility model micro-cultivator clutch, form by handle, bulb and gear frame, bulb is installed in the handle upper end, handle places in the gear frame that is connected with the mini-size tillage machine frame, places the handle, at its lower end in the gear frame to be connected with linkage, linkage by hinge and place engine and frame between the translation mechanism flexible connection, fixedly connected with engine in translation mechanism top, the translation mechanism bottom is connected with frame.

Linkage is made up of hinge connector, adjusting rod, pull bar, straight pin and fork, be connected with the internal thread of adjusting rod by screw thread with the hinged hinge connector other end, adjusting rod other end internal thread is connected with the pull bar threaded one end, the pull bar other end is connected with the fork lower end by straight pin, position near the fork upper end is provided with the straight pin that can play point action and fixedly connected with frame, this straight pin and fork are and are rotationally connected, and fork is connected with handle.

Translation mechanism is made up of engine base plate, roller, bearing pin, base plate and guide rail, be processed at cross section on engine base plate two outsides of channel-section steel shape and be vertically installed with a plurality of bearing pins symmetrically, on a plurality of bearing pins, roller is installed, the roller outer round surface rolls with backplate surface on being connected frame and contacts, there is cross section to be the guide rail of L shape in the roller arranged outside, the minor face that cross section is L shape guide rail should stretch to roller, and roller is covered.

On the gear frame, be processed with and be convenient to the cavity that is the character cut in bas-relief shape that handle is movable and locate.

After adopting this structure, because in the gear frame that has adopted handle to place to be connected with the mini-size tillage machine frame, place the handle, at its lower end in the gear frame to be connected with linkage, linkage by hinge and place engine and frame between translation mechanism flexibly connect, fixedly connected with engine in translation mechanism top, the translation mechanism bottom is connected with frame, therefore, only need handle is pushed away forward, just can engine be moved backward by linkage, make belt be in relaxed state, realization from purpose, otherwise with handle toward post-tensioning, just can be by linkage with engine toward moving forward, make belt be in tensioning state, realize the purpose of closing; Again since translation mechanism contact with backplate surface rolling on being connected frame by the roller outer round surface, so, show that through actual measurement this is simple in structure, Operation and maintenance are all very convenient, are suitable for manipulating because of strong labour power the elderly, the womankind who stays poverty-stricken area and mountain area that go out to do manual work.

The utility model is described in further detail below in conjunction with drawings and Examples for description of drawings.

Fig. 1 is that the master of the utility model micro-cultivator clutch looks schematic diagram.

Fig. 2 is that schematic diagram is looked on the right side of the utility model micro-cultivator clutch.

Fig. 3 is the schematic top plan view of the utility model micro-cultivator clutch gear frame.

Among the figure: 1. engine 2. guide rails 3. rollers 4. translation mechanisms 5. base plates 6. hinges 7. hinge connectors 8. adjusting rods 9. linkages 10. pull bars 11. straight pins 12. forks 13. gear framves 14. handles 15. bulbs 16. engine base plates.

Embodiment the utility model micro-cultivator clutch shown in Figure 1, form by handle 14, bulb 15 and gear frame 13, bulb 15 is installed in handle 14 upper ends, handle 14 places in the gear frame 13 that is connected with the mini-size tillage machine frame, place handle 14 lower ends in the gear frame 13 to be connected with linkage 9, linkage 9 is by hinge 6 and place the translation mechanism 4 between engine 1 and the frame to flexibly connect, and fixedlys connected with engine 1 in translation mechanism 4 tops, and translation mechanism 4 bottoms are connected with frame; Linkage 9 is made up of hinge connector 7, adjusting rod 8, pull bar 10, straight pin 11 and fork 12, hinge connector 7 other ends that are connected with hinge 6 are connected by the internal thread of screw thread with adjusting rod 8, adjusting rod 8 other end internal threads are connected with pull bar 10 threaded one ends, pull bar 10 other ends are connected with fork 12 lower ends by straight pin 11, position near fork 12 upper ends is provided with the straight pin 11 that can play point action and fixedly connected with frame, this straight pin 11 is with fork 12 and is rotationally connected, and fork 12 is connected with handle 14; Translation mechanism 4 shown in Figure 2 is made up of engine base plate 16, roller 3, bearing pin, base plate 5 and guide rail 2, be processed at cross section on 16 liang of outsides of engine base plate of channel-section steel shape and be vertically installed with a plurality of bearing pins symmetrically, roller 3 is installed on a plurality of bearing pins, roller 3 outer round surface roll with base plate 5 surfaces on being connected frame and contact, there is cross section to be the guide rail 2 of L shape in roller 3 arranged outside, the minor face that cross section is L shape guide rail 2 should stretch to roller 3, and roller 3 is covered; The cavity that is the character cut in bas-relief shape of being convenient to handle 14 activities and location that on gear frame 13, is processed with shown in Figure 3.

When the utility model is in running order, earlier handle 14 is pushed away forward, by linkage 9 engine on the translation mechanism 41 is moved backward, make belt be in relaxed state, ato unit 1 then, again with handle 14 past post-tensionings, and just can be by linkage 9 with the 1 past reach of the engine on the translation mechanism 4, make belt be in tensioning state, reach the purpose of closing.
