Description
Technical field
The utility model relates to the ground wheel mechanism of agricultural machinery, exactly is a kind of land wheel relocation mechanism that is used on the agricultural machinery such as sower, fertilizer distributor.
Background technology
The effect of the land wheel in the agricultural machinery such as sower, fertilizer distributor is generally two, the one, be used for walking, the 2nd, sprocket wheel is installed, by on the sprocket wheel in the sprocket wheel on land axle and sowing or the fertilizer apparatus chain being installed, by land wheel transmission sowing or fertilizer apparatus on land axle.The structure of existing a kind of land wheel relocation mechanism is: land axle is equipped with in the lower end at wheel carrier, and land axle is provided with land wheel, and support is passed in wheel carrier upper end, the upper end of the spring that is with on the wheel carrier and the bottom of support against.Be contained in this land wheel relocation mechanism the walking of the land wheel on the land axle when rugged field, can guarantee that by spring land wheel contacts with ground all the time, and when running into obstacle in land wheel walking, land wheel can float upwards, and the spring on the wheel carrier is compressed, guarantee that land wheel passes through obstacle smoothly.The deficiency that above-mentioned this land wheel relocation mechanism exists is: when 1, running into obstacle in the land wheel walking, the vertical stress component of being taken turns active force by obstacle over the ground upwards floats it, therefore, the scope that land wheel upwards floats is less, upwards unsteady dumb, when the height of obstacle was big, land wheel was difficult to pass through obstacle; 2, land wheel is upper and lower when unsteady, wheel carrier is relative to upper and lower the moving of support meeting, on the sprocket wheel on the land axle with sowing or fertilizer apparatus in sprocket wheel on the tightness of the chain adorned also can change thereupon, for addressing this problem, need be provided with separately again chain stretching device.
The utility model content
The purpose of this utility model is to provide a kind of land wheel relocation mechanism, and the scope that the land wheel in this land wheel relocation mechanism floats flexibly, upwards floats is big, and when land wheel floated, wheel carrier rotated relative to support.
For achieving the above object, the utility model adopts following scheme: the land wheel relocation mechanism, include wheel carrier and support, land axle is equipped with in the wheel carrier lower end, one end of land axle is equipped with land wheel, and the upper end and the support of wheel carrier are hinged, and the wheel carrier bottom is hinged with the lower end of a guide rod, support is passed in the upper end of guide rod, is with spring on guide rod.
By such scheme as seen, the land wheel in this land wheel relocation mechanism can guarantee that land wheel contacts with ground all the time under the effect of guide rod upper spring, and land wheel is capable when running into obstacle in advancing, land wheel can make progress flexibly float and domain of walker big.In addition, upper and lower when unsteady at land wheel, wheel carrier rotates relative to support, and promptly the pin joint with support rotates land axle around the wheel carrier upper end, between land axle and this pin joint apart from constant.Therefore, this land wheel relocation mechanism is arranged on the frame of sower or fertilizer distributor, sprocket wheel is installed on land axle, and on the axle of hinged wheel carrier and support, a pair of gap bridge sprocket wheel is installed, after on a sprocket wheel on the land axle and the gap bridge sprocket wheel chain being installed, no matter how land wheel floats, and the distance between sprocket wheel on the land axle and gap bridge sprocket wheel is constant, can save chain stretching device.
Description of drawings
The structure chart of Fig. 1 the utility model one embodiment;
The right view of Fig. 2 Fig. 1.
Embodiment
Further specify the utility model below in conjunction with embodiment and accompanying drawing.
Referring to Fig. 1
The land wheel relocation mechanism that the utility model provides includes wheel carrier 10 and support 2, and land axle 8 is equipped with in wheel carrier 10 lower ends, and land wheel 9 is housed on the land axle 8, and 2 on the upper end of wheel carrier 10 and support are hinged by wheel shaft 3.The hinged mode in the lower end of wheel carrier 10 bottoms and a guide rod 5 is, is fixed with an otic placode 7 in wheel carrier 10 bottoms, and the lower end of guide rod 5 and otic placode 7 are hinged.Be with spring 6 on guide rod 5, support 2 is passed in the upper end of guide rod 5.One end and one " U " the shape fixed mount 1 of support 2 is affixed, connects by the frame of fixed mount 1 with sower or fertilizer distributor, and this land wheel relocation mechanism is arranged on the frame of sower or fertilizer distributor.In addition, can not break away from support 2 for guaranteeing guide rod 5, the upper end of guide rod 5 is fixed with backing pin 4.
Referring to Fig. 2
Bearing 15 is housed on the land axle 8, and land axle 8 is contained in the lower end of wheel carrier 10 by bearing 15.Land axle 8 an end land wheel 9 is housed, the other end is equipped with sprocket wheel 14, and a pair of gap bridge sprocket wheel 12 is housed on the wheel shaft 3, this is made for an integral duplex sprocket wheel to gap bridge sprocket wheel 12.
As seen from Figure 1, be contained in that the land wheel on the land axle 89 can guarantee that land wheel 9 contacts with ground all the time in this land wheel relocation mechanism under the effect of guide rod 5 upper springs 6, and land wheel 9 is when running into obstacle in advancing, land wheel 9 can make progress and float flexibly.In addition, upper and lower when unsteady at land wheel 9, land axle 8 rotates around the pin joint of wheel carrier 10 upper ends and support 2, and promptly the distance between land axle 8 and the wheel shaft 3 is constant.
As seen from Figure 2, after this land wheel relocation mechanism is installed on the frame of sower or fertilizer distributor, chain 13 is being installed on a sprocket wheel on the land axle 8 14 and the gap bridge sprocket wheel 12, on the sprocket wheel in another gap bridge sprocket wheel 12 and sowing or the fertilizer apparatus, chain 11 is being installed, after constituting chain-drive mechanism, can be by land wheel 9 by chain 13,11 transmission sowing or fertilizer apparatuses.Upper and lower when unsteady at land wheel 9, the distance between land axle 8 and the wheel shaft 3 is constant, and therefore, the tightness of chain 13 can not change, and chain stretching device can be set.
