Abstract
The utility model provides a miniature agricultural cultivator with a single caterpillar band, which is mainly composed of an engine, a machine seat, a speed change box, an arm rest type operating mechanism, a clutch, a belt transmission mechanism, a rolling harrow, a transmission box of the rolling harrow, a ploughshare and a running mechanism. The utility model is characterized in that the running mechanism is composed of a drive sprocket, a front guide wheel and a chain type caterpillar band. The ploughshare is arranged on the front end of the running mechanism, and the engine is arranged on the forwards inclined plane of the machine seat above the running mechanism. The utility model has the advantages of small size, light weight, simple structure, convenient and flexible operation, low price, etc. and is particularly suitable for mechanized plough in small farmlands or terrace lands, such as mountain areas, hills, sloping fields, etc.
Description
The utility model belongs to a kind of improved agricultural tillage machine tool, the miniature agricultural tillage machine of particularly a kind of mono-track.
In prior art, the agricultural tillage machine tool mainly contains wheel or tractor and two kinds of two crawler tractors.Advantages such as it is fast that these two kinds of agricultural tillage machine tools have ploughing speed, and farming efficient height and allocation function are many are used widely in the rural area of part in China very much.Yet, these two kinds of agricultural tillage machine tools also have following weak point: its volume is big, Heavy Weight, radius of turn is big, and their running gear is all than broad, therefore can only in offering the farmland of tractor road, use, can't on haggard such as mountain area, hills and hillside fields and terraced fields, carry out farming.China also has the rural area of many above-mentioned landform, how to make these areas realize the problem that tillage machineryizatioies person that become the agricultural working machine is badly in need of solving.
The purpose of this utility model at the deficiency of existing agricultural tillage machine tool, provides a kind of simple in structure just, operation easily, and low price can be fit to the miniature agricultural tillage machine of mono-track of mountain area and hilly ground farming.
Task of the present utility model ground is realized by this way: this tiller includes ploughshare, support, engine, clutch and belt gear, gearbox, roll rake teeth wheel transmission case, roll rake, handrail-type operating mechanism and running gear are formed, it is characterized in that running gear is by drive sprocket, front jockey wheel and a chain type crawler belt constitute, drive sprocket is connected with gearbox by the linked transmission case of side, front jockey wheel is connected with support by support, ploughshare also is fixed in the front end of running gear by support, engine is arranged at the running gear top on the support plane of top rake.
The utility model is work like this: the moving knife that engine produces is passed to gearbox by belt gear and clutch, roll rake and drive sprocket rotation by rolling rake teeth wheel transmission case and the driving of side linked transmission case again, drive sprocket just drives the chain type caterpillar drive and this tiller is moved forward, by the handrail-type operating mechanism just can handle tiller direction of advance and turn to.
From the unitary construction of this tiller as seen, its complete machine is the rigid body of a right angled triangle framework, the chain type crawler belt form right angle leg-of-mutton base of ploughshare bottom below running gear, the support plane of plowpoing and inclination and handrail-type operating mechanism be the form right angle hypotenuse then, and gearbox rolls the then leg-of-mutton vertical edges of form right angle of rake teeth wheel transmission case and side linked transmission case.Because engine is arranged on the hypotenuse of this right angled triangle framework, the vibration that engine produced just reaches plough body immediately, especially on plowpoing and the rolling rake, makes the earth of contact very fast loose, reduce the plow harrow resistance greatly and the resistance of raking the soil level, and improved cultivating quality.In addition, because it is ploughshare is preposition, the vertical stress component of soil resistance becomes mini-size tillage machine " counterweight forces " in the time of can utilizing ploughing, overcome this mini-size tillage machine because of the problem that influences performance tractive force (being propulsive force) in light weight, make the attachment coefficient of chain type crawler belt bring up to 1.11～1.51, but the engine of adapted low-power just obtain satisfied traction effect.Its three because the chain type crawler width is very little, and operating mechanism, can also be walked even without tractor road at the rear of complete machine, but also can climb pivot turn.Therefore, compared with the prior art this tiller has advantages such as volume is little, in light weight, simple in structure, flexible to operation and cheap, but also has the advantages that tillage resistance is little, cultivating quality good and effective traction is high.This shows that this tiller has overcome the deficiency of existing tillage machinery, the most suitable mountain area, use on the fritter field in hillside fields or the terraced fields on the hills, makes these areas can realize tillage machineryization.
Below in conjunction with accompanying drawing structure of the present utility model is further described.
Fig. 1 is the schematic diagram of a kind of concrete structure of the utility model.
With reference to Fig. 1, the utility model is by ploughshare 1, support 2, and engine 3, clutch and belt gear 4, gearbox 5 rolls rake teeth wheel transmission case 6, rolls rake 7, and handrail-type operating mechanism 8 and running gear 9 are formed.The handrail-type that has a brake gear is operated machine and 8 is fixed in gearbox 5 rear portions, and the front end of gearbox 5 is connected with support 2, and engine 3 is loaded onto on the last plane that support 2 tilts, and engine 3 power take-offs are connected with gearbox 5 with belt gear 4 by clutch.By drive sprocket 13, the running gear 9 that front jockey wheel 10 and chain type crawler belt 12 are formed is arranged at engine 3 belows, the equidistant tooth plate 15 that is provided with on the chain type crawler belt, and drive sprocket 13 is connected with gearbox 5 by chain drive case 14.Front jockey wheel 10 is supported on the support 11 that links with support 2.Ploughshare 1 is fixed in the front end of running gear 9 by support 11.The rearmounted rake 7 that rolls is connected with gearbox 5 by rolling rake teeth wheel transmission case 6.
When implementing the utility model, stationarity when improving the complete machine farming, be unlikely producing deflection, the center line of the center of ploughshare 1, front jockey wheel 10 and drive sprocket 13, the center of gravity of engine 3, gearbox 5 and the center line of handrail-type operating mechanism should be on same longitudinal vertical planes.For the plough point that makes ploughshare 1 produces bigger vibration, the plough point of ploughshare 1 will be higher than 10～15 millimeters at chain type crawler belt 12 tooth plates supporting horizontal plane, ploughshare 1 just becomes a lever that suspends like this, produces bigger dither effect, further reduces tillage resistance and improves cultivating quality.In order to make tiller that enough tractive force be arranged and to stand on the level land, the width of the tooth plate 15 of chain type crawler belt 12 is with 90～110 millimeters, and the tooth plate distance is suitable for 90～110 millimeters, and tooth plate 15 numbers of ground connection are not less than 5 at least.In order to make this tiller be convenient to operation, the height of machine gravity should be less than 360 millimeters, and the longitudinal center of gravity vertical line is being suitable in the 60 millimeters scopes in distance drive sprocket 13 axial line the place aheads.
