Description
Technical field
The invention belongs to farming mechanical automation apparatus field, be specifically related to a kind of agricultural seeding machine with support arm damping running gear.
Background technology
China is as large agricultural country, and because the restriction of Industry Development Level and rural area exist very huge human resources, the degree of Chinese Agricultural Mechanization is still lower, and manual operation and hand tools are still occupied an leading position.Because cultivated land resource is precious, must makes the best use of the situation and accomplish abundant use, especially be distributed in the arable land that mountain and hill is rugged, cannot large area concentrate use to combine to cultivate or grain header, any equipment is all difficult to freely advance, and can only rely on handwork, but efficiency is extremely low, labour intensity and difficulty very big.
In view of the foregoing, applicants have invented a kind of automation agricultural seeder machinery of operation of freely can advancing on mountain region, single Gansu Province, traveling process steadily shakes little.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of agricultural seeding machine with support arm damping running gear, and operation of freely can advancing on single Gansu Province, mountain region, make seeding machinery can adapt to mountain region tillage system reform, and steadily vibrations of advancing is little.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of agricultural seeding machine with support arm damping running gear, comprise frame, characterized by further comprising running gear and sowing mechanism, described running gear comprises plural road wheel, described road wheel passes through road wheel support installing in frame, described road wheel support is by motorized pulleys connected row travelling wheel, described road wheel comprises elastic pin shaft, wheel hub and more than the four cantilever type support arms arranged in pairs, one end of support arm is hinged on wheel hub, the other end of support arm connects grabs ground travel wheel, in support arm overcoat dress elasticity rubber wheel case.
Described ground travel wheel of grabbing comprises center-wheel arbor, at wheel outer shaft sleeve dress elasticity cover, described resilient sleeve is hollow rubber cover, in hollow rubber cover, some elasticity liquid capsules are set, be set with outward in resilient sleeve and sting retainer ring with grabbing, the blunt end stung with grabbing is fixed on by spring fitting and stings in retainer ring with grabbing, and the tip stung with grabbing passes stings retainer ring with grabbing; Be set with elastic caoutchouc wheel case grabbing in ground travel wheel, acanthopore offered by described elastic caoutchouc wheel cover, stings with grabbing and can pass acanthopore.
At the stage casing of support arm hinged porous pin joint axle; The porous pin joint axle that the support arm be oppositely arranged is installed is fixed together by pin plug-in mounting, or is connected and fixed by spring.
The invention has the beneficial effects as follows:
1, at wheel outer shaft sleeve dress elasticity cover, described resilient sleeve is hollow rubber cover, in hollow rubber cover, some elasticity liquid capsules are set, be set with outward in resilient sleeve and sting retainer ring with grabbing, the blunt end stung with grabbing is fixed on by spring fitting and stings in retainer ring with grabbing, and the tip stung with grabbing passes stings retainer ring with grabbing; Be set with elastic caoutchouc wheel case grabbing in ground travel wheel, acanthopore offered by described elastic caoutchouc wheel cover, stings with grabbing and can pass acanthopore.The mode that the design of originally grabbing ground travel wheel adopts wheel shaft to be connected with outer rim elasticity, effectively can alleviate the damage impacted and bring.
2, sting the mode adopting elasticity to install with grabbing; pass from the elastic caoutchouc wheel cover as crawler belt; not only facilitate and walk on soil; earth-grasping force is strong; and when sting with grabbing be retracted in elastic caoutchouc wheel case time, can also remove to stick to and sting mud with grabbing, make equipment durable in use; even if advance in viscosity or the larger face, soil of humidity, also without the need to frequent shutdown cleaning road wheel.In addition, when this equipment travels on road surface, sting forced contraction with grabbing in elastic caoutchouc wheel case, damage can not be caused to smooth bituminous paving, facilitate equipment to advance between zones of different, and without the need to using extra transport agent, more convenient practicality.
3, when this device is in the field walking that Gansu Province height is fixing, the overlap length of the porous pin joint axle that the support arm that only need be oppositely arranged by adjustment overlaps mutually, thus regulate support arm to open amplitude along hinge point, then fixed, now because road wheel can not damage Gansu Province, field by pressure by pin plug-in mounting.When this device, need be linked together between porous pin joint axle by spring during high formula field, unfixed mountain region walking in Gansu Province, what such road wheel automatically can regulate support arm in advance process opens amplitude, is convenient to the farming adapting to multiple landform.
4, structural refinement of the present invention, is suitable for practicality, produce and use cost lower, be suitable in the industry cycle popularize.
