Description

A kind of frame of self-propelled sprayer
Technical field
The present invention relates to a kind of frame of self-propelled sprayer of agricultural mechanical field, more particularly, to a kind of high-clearance is from walking The frame of formula four-wheel boom sprayer.
Background technology
With the attention to agricultural production for the country, the outstanding problem of agricultural modernization development is put in face of us.A few years ago China by main attention be used in development cultivate and the equipment of autumn harvest aspect on, and to the protection equipment in mid-term plant growing stage be Equipment for plant protection, other two aspects that compare will fall behind.Country starts to increase to the subsidy of agricultural machinery policy, related enterprise simultaneously within nearly 2 years Industry also begins to increase the research and development to large-scale equipment for plant protection, and current China does not also have preferably large-scale equipment for plant protection, and some areas have Introduce the large-scale equipment for plant protection of foreign country, but expensive, increase cost to various places farm machinery station and user, simultaneously after-sale service Relatively difficult.
China's current part relevant enterprise, has begun to the research and development to this field devices, and main appearance is following several at present Dummy device:1st, a kind of frame of existing market adopts two-part portal-framed structure, and that is, forward and backward door frame is connected using middle gap bridge, leads to Cross hydraulic jack promote forward and backward door frame relatively rotate to complete turning function;Because the carrying of door frame bridge portion is excessive, And four-wheel boom sprayer drug loading typically ratio is larger, in practical application, vehicle integrally may occur centre to fracture when walking Fault occur, damage to equipment, personnel, cannot adapt at all field extreme environment application.And forward and backward door frame split knot Structure, manufactures complicated, outward appearance is not graceful.2nd, another kind of skeleton using similar this patent, but it is rigidly connected in unitized frame, OK There is no shock-absorbing function during sailing, make the position that is rigidly connected of vehicle be also easy to produce tired looseness fault in advance, driver exists simultaneously In operating process, due to surface relief cause very uncomfortable.3rd, besides the course changing control in frame is unreasonable, other producers Apply on the product, a steering cylinder, using four-bar linkage structure, drive the rotation of four-wheel, due to bar hinge mechanism relatively Many, to end tire turning error super large, hardly result in potential result, synchronization cannot be ensured at all, and accurate controlling angle, And four-bar linkage structure installation and debugging are difficult, make complicated.4th, typically can not adjust for this large-scale equipment for plant protection wheelspan, even if There is wheelspan adjustment function, also can need to complete under the equipment auxiliary beyond vehicle itself, such as sling after unitized frame with crane, Using external force adjustment left and right frame spacing.
