Abstract

The utility model relates to a cultivator which comprises a frame and is characterized in that a cultivating cutter shaft is arranged under the front part of the frame, and an engine is arranged at the rear part and carries out power output through a gearbox; an output shaft positioned on one side of the gearbox is used for driving a cutter shaft at the corresponding side end to rotate through a chain transmission mechanism, an output shaft on the other side is used for driving a single wheel at the middle part of the lower side of the frame to run through a gear speed changing mechanism; and a longitudinal groove notch of a connecting rod on the front side of the frame is also vertically connected with a longitudinal connecting rod with a small single wheel at the lower part. The cultivator ensures the land cultivating depth, has small working resistance, has the speed changing function and can effectively prevent splashed soil blocks from injuring young seedlings during the land cultivation, thereby having wide adaptability.

Description

Cultivator

Technical field

The utility model relates to a kind of cultivator that can be used for weeding, loosens the soil and topdress.

Background technology

Cultivator commonly used at present generally is made up of prolong knot plate, the hand that rises and falls, parallel profiling four connecting rods, plow beam, plowshoe, ploughshare, lifting wall, elevator chain and tilling depth adjusting device; The cultivator that also has, extend two support arms at the housiung separator both ends to rear side, horizontal little square beam of this support arm supporting, on little square beam with corresponding installation one galianconism of ploughshare, the expansion link that the compression spring is housed is contained between the connection seat of galianconism and ploughshare handle rear end, and the penetration performance in arable land is by the control of compression spring.

Obtained in the agricultural production of the cultivator of prior art using comparatively widely, but cultivator tilth commonly used at present can only reach 10-15 centimetre, can not satisfy the requirement of deep ploughing, and this tillage method, make the soil layer below 15 centimetres form a kind of hard tillage pan, do not have and retain and conserve soil moisture, the effect of waterlogging is shouldered in drought resisting, and is unfavorable to crop growth.The ploughshare working resistance is big, and fuel consumption is big, the cost height.In addition, the cultivator ubiquity of prior art time head everywhere the time ploughshare plough and easily ploughed large clod, even overwhelm seedling, unfavorable if topsoil is shallow for time head everywhere to two times times ground, make ridge on time not go up soil layer, influence operation quality.And its running gear speed change gear of the cultivator on the market is simple decelerator, does not have speed-regulating function, and its adaptability is relatively poor.

Summary of the invention

The purpose of this utility model is to provide a kind of cultivator, and this product can not only be guaranteed the degree of depth of ploughing, and working resistance is little, and has speed changing function, and the soil block that splashes can effectively prevent to plough the time injures seedling by a crashing object, wide adaptability.

Of the present utility model being characterised in that: described frame front below is provided with the intertillage cutter shaft, the rear portion is provided with engine, described engine carries out power output through gearbox, the output shaft that is positioned at gearbox one side drives the cutter shaft rotation of corresponding side through chain-drive mechanism, another side output shaft moves through the single wheel that gear shift drives middle side part under the frame, also vertically is connected with vertical connecting rod that the bottom has little single wheel on the vertical notch of connecting rod of described frame front side.

Advantage of the present utility model is: 1, increased the gearbox chain-drive mechanism, can realize speed-regulating function, easily realized the different speeds of travel, can adapt to different farming environment and operating personnel's demand;

2, the position of ploughshare can be regulated according to the different situations of ploughing, and makes the cultivated tooth of ploughshare be easier to go deep into soil layer and reach certain depth, guarantees the degree of depth of farming;

3, this cultivator is for only being provided with a driving wheel, and throttle and clutch are handled and all be located on the handgrip, and be easy to operate, the efficient height; Because machine volume is little, engine just is installed in the top of driving wheel, increases driving force, only needs very little power, uses when being specially adapted to carry out agro-farming operation in the ranks in narrow and small location.

Embodiment

A kind of cultivator, comprise frame 1, described frame front below is provided with intertillage cutter shaft 2, the rear portion is provided with engine 3, described engine carries out power output through gearbox 4, the output shaft that is positioned at gearbox one side rotates through the cutter shaft that chain-drive mechanism 5 drives corresponding side, and another side output shaft moves through the single wheel 7 that gear shift 6 drives middle side part under the frames, also vertically is connected with vertical connecting rod 10 that the bottom has little single wheel 9 on connecting rod 8 vertical notches of described frame front side.

Described chain-drive mechanism comprises a pair of initiative drive shaft that is parallel to each other 11 and passive power transmission shaft 12, be set with a drive sprocket 13 and a driving gear 14 on the described initiative drive shaft, be provided with a driving member cover 15 between described drive sprocket and the driving gear by fork controls, be respectively equipped with driving member on the corresponding side of described drive sprocket and driving gear and driving member cover and overlap the corresponding teeth groove that cooperates, one end of described passive power transmission shaft is provided with a driven gear 16 that meshes with driving gear, the other end is provided with intermediate drive gear 17, is coaxially connected with another driven gear 18 that is driven by middle drive on the described drive sprocket.

When shift fork is upwards stirred when the transmission external member is cooperated with drive sprocket, then initiative drive shaft directly drives drive sprocket and rotates, and by chain with transmission of power to the intertillage cutter shaft; When shift fork is stirred downwards when the transmission external member is cooperated with driving gear, initiative drive shaft drives the driving gear rotation, driven gear engaged transmission on driving gear and the passive power transmission shaft, the rotation of drive driven gear, thereby drive the intermediate drive gear rotation on the driven gear other end, another driven gear engagement on intermediate drive gear and the initiative drive shaft, thereby the drive sprocket on the sky that drive links to each other with this driven gear cover and the initiative drive shaft rotates, and then power is delivered on the intertillage cutter shaft by chain; Use this driving-chain can realize that the two stage speed change of intertilling cutter rotates.

For preventing when intertilling operation, the soil block that splashes injures by a crashing object or buries plant, described intertillage cutter shaft upside be provided with cover body, described cover body is made of the spine with the cover body middle part side cover that is hinged and the extension side cover that is positioned at the outer side of side cover, be provided with between described extension side cover and the side cover connecting portion and scalablely be connected the described side cowl top panel of adjusting part and a connection handle is hinged, described connection handle is provided with several alignment pin perforation along its length, the alignment pin of described connection handle through passing the alignment pin perforation is locked in the top of described spine, described extension side cover is hinged with the scalable adjusting part that is connected, and is provided with hinged positioning and locking device.
