Abstract

The utility model relates to a motor-operated thresher, which comprises a support frame, a threshing cylinder arranged on the support frame and a power machine. The utility model is characterized in that a power casing is fixed with a coupling shaft sleeve; the bearing of the coupling shaft sleeve is positioned with a rotary shaft; the rotary shaft and the output shaft of the power machine are on the same shaft line; the end part of the rotary shaft is fixedly provided with an engaging and disengaging disk; the output shaft is fixedly provided with a tension block; the tension block can contact the engaging and disengaging disk when the tension block is opened; the other end of the rotary shaft and the threshing cylinder form a driving connection. The utility model has the advantages of simple structure and convenient operation. The engaging and disengaging action can be controlled through the oil door of the power machine.

Description

Motor-operated thresher

The utility model belongs to the agricultural machinery field, particularly a kind of improvement of Motor-operated thresher.At present in vast rural area or outlying mountain area, cereal or wheat crops generally all are to adopt the manual type threshing, as foot pedal threshing machine etc.Have now at areas without electricity the motor-driven machine free from vulgarity of use is also arranged, its primary structure includes rack-mount threshing cylinder and engine, power generally adopts belt transmission to give threshing cylinder, must unload belt during the engine starting, otherwise big being difficult to of load started, need again after the starting it is put, operation both bothered, and was dangerous again.And power thresher only is fit to have the electricity area to use.

The purpose of this utility model is to design a kind of Motor-operated thresher by speed control clutch according to engine velocity variations scope.

Task of the present utility model is finished like this, the Motor-operated thresher of threshing cylinder and engine is installed on the support, it is characterized in that being fixed with on the power casing coupling band, the coupling band inner bearing is positioned with a rotating shaft, the output shaft of rotating shaft and engine is on the same axis, and roller end is fixed with the clutch dish, is fixed with tightening piece on the output shaft, can touch the clutch dish after tightening piece opens, the other end of rotating shaft becomes driving coupling with threshing cylinder.In engine when starting or when being in the idling situation, the speed of power machine output shaft is lower,, tightening piece does not open, and is non-loaded; When strengthening the engine throttle, the output shaft faster rotational speed, reach the open thresholding of tightening piece after, tightening piece opens and touches the clutch dish, the rotating shaft that drives in the coupling band is rotated, and makes threshing cylinder work; Of short durationly stop thresher work and only need reduce throttle and get final product if need.

The utlity model has reasonable in design, parts are few, control characteristics easily, are the clutch action of controlled threshing cylinder as long as adjust the throttle of engine, and non-loaded when starting and idling, oil consumption is few; And engine part can descend easily, moves to use it for anything else.

Be described further this reality is novel below in conjunction with concrete legend:

Fig. 1 is the schematic diagram of power thresher

Fig. 2 coupling band generalized section

Comprise threshing cylinder 2 and the engine 3 that is installed on the support 1 with reference to Fig. 1 Motor-operated thresher, be fixed with a coupling band 4 on engine 3 shells, coupling band 4 is provided with leg 44, and leg 44 is positioned at support 1 bolt, make integral body firm, and can support the weight of minitype motivation part.Coupling band 4 inner bearings are positioned with a rotating shaft 41,2 one-tenth driving coupling of the other end of rotating shaft 41 and threshing cylinder, this connection is meant that an end of rotating shaft 41 is fixed with the 21 one-tenth belt driving coupling of big belt pulley on belt pulley 43 and the cylinder shaft, and this kind driving coupling is the most economical and light; Also can adopt gear transmission to connect.

On the basis of above-mentioned thresher, be equipped with foot-operated part and gear train, can realize motor-driven and two kinds of power drives of manpower.Fix a gear 5 at the other end of 2 of threshing cylinders, this gear 5 and foot-operated gear wheel 51 engagements, foot-operated gear wheel 51 is connected by crank 53 with pedal 52, unloads power belt this moment and can drive threshing cylinder 2 by foot-operated power; On carry threshing cylinder 2 and make gear 5 break away from the engagement of gear wheels 51, and be positioned at by nut on the last axial trough of support 1, put power belt and get final product power drive, shown in the figure is exactly this state.

With reference to Fig. 2 coupling band generalized section, coupling band 4 inner bearings are positioned with a rotating shaft 41, rotating shaft 41 is on the same axis with the output shaft 31 of engine 3, rotating shaft 41 ends are fixed with clutch dish 42, be fixed with tightening piece 32 on the output shaft 31, can touch clutch dish 42 after tightening piece 32 opens, and drive rotating shaft 41 and follow output shaft 31 and rotate together, double dot dash line is an engine 3 among the figure.

Engine described in the last example can be diesel engine or gasoline engine, and legend is gasoline engine.The volume of gasoline engine is littler, can finish with its instrument that is power is equipped with various necessity, as: be equipped with that brush machinery can be mowed, brush wood and harvesting crops; Being equipped with water pump can draw water and water, apply fertilizer the spray medicine; Being equipped with shelling machinery can use as rice-wheat threshing.The little the lowest point field operation to field, the mountain that is convenient for carrying in light weight of volume alleviates peasant's labour intensity, and increases work efficiency.
