Abstract
A priction clutch of micro-cultivator is provided. The utility model relates to the gear mechanism of the micro-cultivator for agricultural machinery and garden machinery, in particular to clutch means of the micro-cultivator. The utility model is connected with a driving axle and a dead axle which are coaxial, comprising a driving plate, a clutch plate, a bearing support, a shift fork, a shift fork shaft, a connecting-rod, a tightwire and a clutch handle, wherein the driving plate provided with and an inner conical surface is fixed on the driving axle;. A sliding key of the clutch plate is connected with the dead axle. The clutch plate is arranged on the top with an outer conical surface inosculated with the inner conical surface and is movably connected with a ring support on the out circle of the lower clutch plate. A circumferential groove is arranged on the ring support. The engine block is movably connected with the shift fork shaft with the shift fork positioned inside the circumferential groove. The shift fork shaft is connected with the clutch handle via the connecting-rod and the tightwire. The utility model has compact structure, simple operation, small cubage, and light weight. The high transfer efficiency of the utility model can achieve high efficiency power transmission with low cost, thereby producing better economic benefits.
Description
Technical field
The utility model relates to the transmission mechanism of mini-size tillage machine in agricultural machinery, the graden machine, relates in particular to the arrangement of clutch of mini-size tillage machine.
Background technology
Most structures that adopt the V belt transmission and realize clutch by strainer of mini-size tillage machine in the market, this mini-size tillage machine of realizing clutch with the V belt transmission, with strainer, its clutch configuration ubiquity complex structure, it is big to take up room, inefficiency, the more high defective of cost, manufacturer and use the client that the architecture advances of this mini-size tillage machine clutch is relatively paid attention to always.The manufacturer that has designs the mini-size tillage machine of a kind of plane contact formula friction clutch transmission, driving shaft and driven shaft are coaxially set, establish frictional disk at axle head, contact by controlling the frictional disk plane with separate the clutch that realizes transmission, but the moment of torsion of this type of belt drive transmission is little, inefficiency, the plane formula frictional disk weares and teares easily.
Summary of the invention
The utility model is at above defective, provides a kind of and transmits that moment of torsion is big, mechanical efficiency is high, the friction engaging and disengaging gear of the mini-size tillage machine of cone match formula.
The technical solution of the utility model is: the driving shaft and the driven shaft that connect coaxial setting, it comprises driving disc spacing pressing, clutch plate, the support of bearing, shift fork, declutch shift shaft, connecting rod, cable wire and clutch handle, driving disc spacing pressing is fixedly connected on the driving shaft, be provided with inner conical surface, the driven shaft upper end is connected with the clutch plate feather key, the clutch plate upper end is provided with the male cone (strobilus masculinus) that coincide with the driving disc spacing pressing inner conical surface, be connected with ring support on the cylindrical of clutch plate lower end, ring support is provided with circumferential recess, flexibly connect a declutch shift shaft on the body, its shift fork is inserted in the groove, and declutch shift shaft passes through connecting rod, cable wire links to each other with the clutch handle.
Establish friction lining face on the inner conical surface of described driving disc spacing pressing or on the male cone (strobilus masculinus) of clutch plate.
Declutch shift shaft is provided with back-moving spring.
Connecting rod and cable wire junction are provided with adjusting device.
Taper sleeve type mini-size tillage machine clutch that the utility model provides adopts the Dry Conical Wheel-disk friction techniques to have compact conformation, simple to operate, characteristics such as volume is little, in light weight, transmission efficiency height; Adjusting device also can realize high efficiency transmission of power after making the friction material wearing and tearing; The utility model production cost is lower, can produce favorable economic benefit, and good market prospects and application and popularization value are arranged.
