Abstract
The utility model discloses a lawn cutter which comprises an engine, a transmission system, and a cover, wherein, power in the transmission system is output to belt wheels through the engine, and is transmitted to input belt wheels of a gearbox through an adhesive tape. The input belt wheels of the gearbox are fixedly connected with an input shaft of the gearbox, a left and a right output shafts of the gearbox are extended outside of a left and a right bearing seats through bearings, the left and the right bearing seats are fixed in coaxial notches at the left and the right sides of the back end of the cover, the front end of a tension spring is connected with the gearbox in a hanging way, the back end of the tension spring can be used for adhesive tapes. The fixation of the gearbox of the utility model is changed from rigid connection to tension spring connection, the gearbox and the belt wheels can be swung in a minor angle around the front and back of output shafts, the adhesive tapes are in a tension state all the time under the action of the tension spring, the reliable transmission of the power is guaranteed, and the adhesive tapes and a gearbox casing are protected.
Description
Affiliated technical field
The utility model relates to the hay mower field.
Background technology
Present existing hay mower is when work, and what the output pulley of engine to the strainer between the input belt wheel of gearbox was used is rigid attachment, and drive belt tensioning difficulty causes adhesive tape to wear and tear greatly and the damage of gear box casing.In addition, the structure of case has some setbacks Lysimachia sikokiana, stops up easily.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, to provide a kind of mowing and Lysimachia sikokiana performance better following type hay mower.
The technical solution adopted in the utility model is: the utility model comprises engine, transmission system and case, power in the transmission system exports belt wheel to by engine, reach the input belt wheel of gearbox again by adhesive tape, the input belt wheel of gearbox is fixedlyed connected with the power shaft of gearbox, the left and right output shaft of gearbox stretches out from the Y-axis bearing by bearing, the Y-axis bearing is fixed in the coaxial notch in the left and right sides, case rear end, have an extension spring front end and gearbox to articulate, the rear end can act on adhesive tape.
The utility model adopts the beneficial effect behind the such scheme to be: gearbox fixing used extension spring instead and connected by being rigidly connected; can make gearbox and belt wheel small angle oscillation before and after output shaft; adhesive tape is under the effect of extension spring; all the time be in tensioning state; guarantee the reliable delivery of power, protected adhesive tape, gear box casing.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the enlarged diagram of casing structure among Fig. 1.
Embodiment
As shown in Figure 1, the utility model comprises that case 1, engine 18, engine 18 are fixedly connected on case 1, be fixedly connected belt wheel 2 and revolve cutter 17 of the output shaft of engine 18.Power exports belt wheel 2 to by engine 18, reach the input belt wheel 4 of gearbox 10 again by adhesive tape 3, the input belt wheel 4 of gearbox 10 is fixedlyed connected with the power shaft of gearbox 10, the output shaft 9 of gearbox 10 stretches out from Y-axis bearing 7 by bearing, Y-axis bearing 7 is fixed in the coaxial notch 11 of the left and right sides, case 1 rear end face, described left and right output shaft 9 outer ends also are connected with pinion 6, pinion 6 and 16 engagements of driving wheel ring gear, gearbox 10 and belt wheel 4 just can be around left and right output shaft 9 small angle oscillations.There is the column 5 on an extension spring 14 front ends and the gearbox 10 to articulate, the rear end articulates with the screw rod 12 that passes on the end plate 15 of case 1, fixing by adjusting nut 13, can act on adhesive tape 3, when gearbox 10 and belt wheel 4 rotations, adhesive tape 3 is under the effect of extension spring 14, all the time be in tensioning state, guaranteed the reliable delivery of power, simultaneously can be according to the girth difference of adhesive tape 3, by the position of adjusting nut 13, guarantee the constant of adhesive tape 3 tensile forces, thereby guarantee that the suffered pulling force of gearbox 10 shells is no more than the limit.
As shown in Figure 2, case 1 has a cylinder D and constitutes its lateral surface, spiral raised floor F constitutes the end face of Lysimachia sikokiana passage 21, conical surface H constitutes the medial surface of Lysimachia sikokiana passage 21, face B, D, E, H has formed the Lysimachia sikokiana passage 21 of case 1, face I, J, the afterbody of A and F forms the straw outlet 20 of case 1, G is for revolving the cutter direction of rotation, along revolving the cutter direction of rotation, locate from K to C, Lysimachia sikokiana passage 21 cross sections become greatly gradually, between the straw outlet 20 of case 1 and lateral surface D, be provided with a plane B and the D face tangent, plane B has guide functions to the broken grass under cutting, make Lysimachia sikokiana more freely suitable, the difficult obstruction.
