Abstract

The utility model relates to a four-wheel driving four-wheel turning self-propelled spraying car for protecting plants. An auxiliary connecting rod is extended from a front turning handle on a chassis, the end of the auxiliary connecting rod is connected with a rear turning handle, and a rear turning connecting rod is connected between the rear turning handle and a rear turning hub, so that a four-wheel turning mechanism is formed. The four-wheel turning mechanism can be matched with a drive system which is composed of a gear box, and a front and a back speed shafts which are connected, so that the utility model can generate ultra-strong driving forces and has the function of a small gyration radius, and can move freely on bumpy and muddy roadways and among narrow fruit trees. Accordingly, the purposes of increasing running flexibility, saving manpower and material, enhancing pesticide spraying efficiency for protecting plants and increasing crop harvest can be obtained.

Description

Four wheel driving four wheel turning self-propelled spraying car for plant

The utility model relates to the self-propelled plant protection spray truck of a kind of four wheel drive four-wheel steering, it is a kind of manoevreability, alerting ability height, can travel on the not good orchard of operating environment (as paulin posture crop gardens such as vineyard, theatre) effectively, give full play to the plant protection spray truck of its function; Mainly be to stretch an auxiliary connecting rod preceding turning to handle to connect, the mat auxiliary connecting rod, after turn to handle and back Linkage steering to constitute four-wheel steering mechanism, make it significantly to dwindle radius of turn, improve road mobility, effectively bring into play the function of orchard operation.

The two-wheeled that is all the front-wheel running by the steering swivel system of general traditional type automatic wheel turns to form, that is when steering wheel rotation, its steering swivel system is just controlled and made front-wheel steering.Yet, because road surface, orchard and the poor environment factor when travelling, for preventing slight skidding, must diff is locked so that left and right wheels can have propulsive effort simultaneously, thereby the rotating speed difference of foreign steamer in when produce turning, make trailing wheel partly have one thrust outward, and the radius of turn that forces whole machinery becomes big, and, the radius of turn of machinery itself is become greatly more, and the radius of turn change has following shortcoming greatly owing to can produce centnifugal force when turning:

1. the line-spacing of fruit tree is quite little in the cause and effect garden, thereby if single just excessive because of radius of turn often by front-wheel steering, turn to and to pass through and must repeatedly move backward to revise, not only to lose time, and in the process that reversing correction turns to, also to hit fruit tree easily and cause cataphoretic failure.

Moreover, because of the structural form of front-wheel steering, trailing wheel is leaned on do relative slippage to cooperate front-wheel steering with ground, yet, the friction force that slippage produced easily makes wear on tyres, and after fruit tree spray medicine mostly concentrates on it rained just now opportunity, and this moment, the road surface, orchard muddyly can't bear, and added escape canal ponding, so the car body that traditional two-wheeled turns to just can cause serious skidding, and cause the difficulty of advancing, even can't operate, and mechanism body is produced bad destruction.

Main purpose of the present utility model is: provide that a kind of radius of turn is little, the maneuverability height, can fill part spray truck of performance orchard operation usefulness; It is to stretch an auxiliary connecting rod by preceding turning to handle to connect, and auxiliary connecting rod through after turn to handle and link to constitute four-wheel steering mechanism with the back Linkage steering, its front and back wheel can be cooperated turns to synchronously, significantly to dwindle radius of turn, and then the raising road mobility, effectively bring into play the function of orchard operation.

The utility model provides a kind of four wheel drive four-wheel steering self-propelled plant protection spray truck, be primarily characterized in that: be connected with a main connecting rod on the actuator lever of the rotating shaft bottom power conversion mechanism of bearing circle on the ride, and before being connected with one, the main connecting rod end turns to handle, turn to handle to be provided with a central siphon before being somebody's turn to do, central siphon is equipped with anchor shaft and pivot is fixed in ride, turn in addition and also be provided with two preceding Linkage steering and auxiliary connecting rods on the handle respectively, its two preceding Linkage steering links to the both sides extension and with preceding turning to hub respectively, auxiliary connecting rod then to the ride rear side extend and with after turn to handle to link, turn to and also be provided with central siphon on the handle thereafter, and central siphon also wears anchor shaft and pivot is fixed on the ride, and after turn to handle also to be provided with two back Linkage steerings, this two backs Linkage steering respectively to both sides extend and with after turn to hub to link.

The utlity model has the following points advantage:

1. the structural form of four-wheel steering, the maneuverability height can effectively be brought into play the farmland operation function; To be that mat is forward and backward turn to handle 16,21, auxiliary connecting rod 20, forward and backward Linkage steering 17,22 and constitute four-wheel steering mechanism for it, make it have four-wheel and turn to function synchronously, can significantly dwindle radius of turn, improve maneuverability, comply with in ground out-of-flat, the mire and walk about freely, and then fill a part performance operation function.

2. four-wheel steering structure design, front and back wheel can be moved according to surface state, can avoid producing the phenomenon of skidding with wear on tyres; It turns to form synchronously for four-wheel, and when walking in ground uneven or that rubble is arranged and doing when turning to, its front and back wheel all can be done the front along ground and move, thus unlikely generation skidding, and can improve the wearing and tearing that tradition is produced because of sideslip.

Further specify architectural feature of the present utility model and purpose below in conjunction with accompanying drawing.
