Abstract
The utility model relates to a land wheel overrunning transmission mechanism. Various weeders for intertillage and seeding machines at present generally adopt a single land wheel transmission or a double land wheel transmission. By adopting the single land wheel transmission, When the land wheels slip, a discontinuous work can be caused to generate phenomenon of miss plowing and miss seeding. By adopting the double land wheel transmission, because of the fixed coupling, when the land wheels at one side are blocked or the land wheels slip, the work quality is strongly impacted. The land wheel overrunning transmission mechanism comprises land wheel 3, a land wheel 4 and a land wheel shaft 9 which is on the land wheel 3 and the land wheel 4. The shaft end of the land wheel shaft 9 is provided with an overrunning mechanism 2. A driving sprocket 1 is fixed on the overrunning mechanism 2. The driving sprocket 1 is connected with a following driving sprocket 7 which is installed on a middle transmission shaft 6 via a chain 5. The utility model is used for various weeders for intertillage and seeding machines to carry out the power transmission.
Description
Technical field: the utility model relates to a kind of a kind of transmission mechanism of using in agricultural machinery.
Background technology: existing various extirpators, sower generally all adopt single land wheel transmission, when land wheel skids, can cause interrupter duty, cause balking, the broadcast leakage phenomenon; Also there is minority to adopt two land wheel transmissions, but is rigid attachment, stuck or when skidding when a side land wheel, have a strong impact on operation quality; The two ground of the employing that also has wheel drive, differential seeding fertilizer mechanism, but, when being used on the sower, can only guarantee the seeding unit normal operation, and fertilizer apparatus broadcast leakage phenomenon happens occasionally because structure is limit, and it makes all complexity such as processing, assembling, and manufacturing cost is higher.
Summary of the invention: the purpose of this utility model provides a kind of simple in structure, and operation is stable, reliable, and configurable a kind of land wheel in various extirpators and the enterprising action edge transmission of sower surmounts transmission mechanism.
Above-mentioned purpose realizes by following technical scheme:
Land wheel surmounts transmission mechanism, its composition comprises: land wheel and on land axle, the axle head of described land axle is equipped with one-way element, is fixed with drive sprocket on the described one-way element, and described drive sprocket is connected with driven sprocket on being contained in intermediate propeller shaft by chain.
Above-mentioned land wheel surmounts transmission mechanism, and the sprocket wheel or the gear that drive workpiece are housed on the described intermediate propeller shaft.
This technical scheme has following beneficial effect:
1. land wheel of the present utility model surmounts transmission mechanism, and stuck or when skidding, the one-way element of this side is done to surmount motion and made its drive sprocket idle running when a side land wheel wherein, the transmission mechanism of opposite side runs well, thereby has reduced working resistance.
2. this one-way element can be installed in the axle head of two or more land axles of extirpator or sower, in its outside design drive sprocket is arranged, this sprocket wheel articulates by chain with the driven sprocket that is configured on the intermediate propeller shaft, be contained in gear or the work of chain wheel drive operation part on the intermediate propeller shaft, thereby it is simple to reach project organization, the stable and reliable operation purpose.
3. adopt this mechanism can guarantee that the facility transmission is reliable and stable, reduced, thereby increased the output of crop because of balking of causing of ground wheel slip, broadcast leakage phenomenon.
Description of drawings: accompanying drawing 1 is the structural representation of this mechanism.
Below in conjunction with the description of drawings embodiment:
Embodiment 1:
Land wheel surmounts transmission mechanism, its composition comprises: left and right sides land wheel 3,4 and on land axle 9, on the described left and right sides land wheel 3,4 one-way element 2 is housed respectively, drive sprocket 1 is installed on separately the described one-way element 2, be connected with driven sprocket 7 on being contained in intermediate propeller shaft 6 by driving chain 5, the sprocket wheel 8 or the gear 10 that drive workpiece are housed on the described intermediate propeller shaft 6.
Embodiment 2:
Above-mentioned land wheel surmounts transmission mechanism, its course of work is: when facility carry out operation, utilize the rotation of described left and right sides land wheel 3,4, the described drive sprocket 1 that described one-way element 2 drives separately rotates, along with the motion of described chain 5, described driven sprocket 7 is stressed simultaneously and drive the sprocket wheel 8 of the driving workpiece on the described intermediate propeller shaft 6 or gear 10 rotates and make workpiece carry out farm work.
Claims (2)
1. a land wheel surmounts transmission mechanism, its composition comprises: land wheel and on land axle, it is characterized in that: the axle head of described land axle is equipped with one-way element, be fixed with drive sprocket on the described one-way element, described drive sprocket is connected with driven sprocket on being contained in intermediate propeller shaft by chain.
2. land wheel according to claim 1 surmounts transmission mechanism, it is characterized in that: the sprocket wheel or the gear that drive workpiece are housed on the described intermediate propeller shaft.
