The rotary cultivation protection suspension device comprises a down-pulling arm, a lifting pull rod, a middle pull rod, an up-lifting arm and a lifting oil cylinder, wherein the lifting oil cylinder comprises a floating sliding sleeve; one end of the floating sliding sleeve is hinged and fixed to the up-lifting arm, and the other end of the floating sliding sleeve is provided with a center hole matched with a piston rod of the hydraulic oil cylinder; the piston rod of the hydraulic oil cylinder is sleeved in the center hole; the floating sliding sleeve can slide freely by a certain stroke relative to the piston rod of the hydraulic cylinder. During operation, the fixing position of the piston rod of the lifting oil cylinder is adjusted according to a rotary cultivation topographic condition, and the influence of up and down movement of a power chassis on the rotary cultivator due to the fluctuation of a rotary cultivation terrain can be eliminated by making the floating sliding sleeve slide up and down by a certain stroke relative to the piston rod of the lifting oil cylinder, so that the rotary cultivator is always kept in a deadweight pressure rotary cultivation state, and the rotary cultivation effect of the rotary cultivator is ensured.
Description
Technical field
The utility model belongs to agricultural machinery technological field, relates to a kind of crawler type rotovator suspension arrangement, is specifically related to the suspension arrangement with the smooth profiling protection mechanism of rotary tillage of crawler type rotovator.
Background technology
Domestic water paddy field tillage machine tool, due to the limitation of wheel tractor, been has newly has been researched and developed various caterpillar rotovators at present, and these facility have compact conformation, and complete machine is light.Owing to adopting caterpillar walking manner, its ground connection pressure is low, and in paddy field, walking can not be trapped in hard mud layer, is conducive to protect the mud pin in southern paddy field.Thereby this machine is subject to users' favorable comment.
Crawler type rotovator promotes the rotary tillage machine that is suspended on power chassis rear to depart from ground by being connected to the hydraulic lift(ing) cylinder of its suspension arrangement, facilitates complete machine to move at ground running.When operation, according to the situation of operation field, by lift cylinder, rotary tillage machine is lowered into suitable level altitude, by lift cylinder, control the rotary tillage degree of depth, to reaching best rotary tillage effect.But because the paddy field field area of current southern area of China is little, environment is severe, operating condition exists huge mobility, uncontrollability, we find that new line phenomenon at power chassis ending of the dog days appears in crawler belt rotovator when by ridge or hollow area in actual use, the rotary tillage machine being suspended on after power chassis can be pressed down.The lift cylinder of existing crawler type rotovator is fixing locked oil cylinder, not according to the ability of the variation timely adjustment rotary tillage machine suspension height of rotary tillage orographic condition, thereby cause rotary tillage machine below sink machine by after stay one or more groove of field and dell, be therefore necessary crawler type rotovator suspension arrangement to improve.
Utility model content
The purpose of this utility model is for existing crawler belt rotovator sprung parts technology and the defect existing in using; propose a kind ofly to have according to the suspension height of rotary tillage orographic condition timely adjustment rotary tillage machine; guarantee that rotary tillage machine keeps profiling rotary tillage; solve that power chassis comes back and the rotary tillage protection suspension arrangement of the crawler belt rotovator of the phenomenons such as digging pit of occurring, make it be applicable to the rotary tillage process requirement under various environment.
The utility model solves the problems of the technologies described above adopted technical scheme, and a kind of rotary tillage protection suspension arrangement of crawler belt rotovator, comprises lower arm, raising rod, intermediate draw bar, upper lift arm and lift cylinder; Described intermediate draw bar is articulated and connected fixing with rotary tillage machine and power chassis respectively; Described lower arm is hinged and is connected with rotary tillage machine, power chassis and described raising rod respectively; Described upper lift arm is hinged fixing with power chassis, described raising rod and lift cylinder respectively; Described lift cylinder also comprises unsteady sliding sleeve, on the hinged fixing described upper lift arm in described unsteady sliding sleeve one end, the other end of described unsteady sliding sleeve offers the centre bore matching with the piston rod of described hydraulic jack, the piston rod of described hydraulic jack is set in described centre bore, and the piston rod that described unsteady sliding sleeve can relatively described hydraulic cylinder is free to slide certain stroke; During operation, according to rotary tillage orographic condition, adjust the fixed position of the piston rod of described lift cylinder, guarantee that the piston rod that described unsteady sliding sleeve can relatively described lift cylinder slides up and down certain stroke, the impact of the dipping and heaving of the power chassis causing with elimination rotary tillage hypsography on rotary tillage machine, thereby guarantee that rotovator is always in gravity pressure rotary tillage state, and have nothing to do with the walking situation of power chassis, guaranteed the rotary tillage effect of rotovator.
In the utility model, on the piston rod of described lift cylinder, offer limited step, prevent that the piston rod top of described lift cylinder and described unsteady sliding sleeve from impacting, and guarantees the normal use of described unsteady sliding sleeve.
In the utility model, when when nonirrigated farmland pan soil ground field is carried out rotary tillage process, because field is really up to the mark, by rotary tillage machine, conduct oneself with dignity and be difficult to reach the rotary tillage degree of depth of expection, cannot guarantee rotary tillage effect, at this moment need to make rotovator in rotary tillage process, to guarantee the fixing rotary tillage degree of depth, to guarantee rotary tillage effect.In order to address this problem, on the piston rod of described lift cylinder and unsteady sliding sleeve, offer a plurality of corresponding pin-and-holes and set and suppress stop pin, adjust after the rotary tillage height of rotary tillage machine, described in inciting somebody to action, suppressing stop pin injects in corresponding pin-and-hole locked, in rotary tillage process process, rotary tillage machine is subject to the downforce of self gravitation and power chassis simultaneously, guarantees that rotary tillage machine carries out rotary tillage process in the rotary tillage degree of depth of setting.
In the utility model, on the piston rod of described lift cylinder and unsteady sliding sleeve, offer respectively three corresponding pin-and-holes.
The utility model is mainly to increase and float sliding sleeve and suppress stop pin on the lift cylinder of original three point linkage, when rotary tillage process circumstance complication, be suspended on power chassis rotary tillage machine below guarantee that by the sliding sleeve that floats rotary tillage machine is in profiling rotary tillage always, the impact of the walking situation of getting rid of power chassis on rotary tillage machine, has guaranteed the rotary tillage effect of rotovator.When field hardness is excessive and when smooth, first rotary tillage machine is dropped to the suitable degree of depth before the operation of going to the field, then with powerful stop pin will float sliding sleeve and lift cylinder locked, and then guarantee the rotary tillage degree of depth.Compare with the suspension arrangement of prior art, the utility model has improved stationarity and the planarization of rotovator in rotary tillage process, and when there is catastrophic failure, self-protection in time, avoids field to damage, and stronger to the adaptability of rotary tillage environment.
