Current, market does not have the matured product that to enter field walking in rice wheat whole vegetative period, exist and sink and be with seedling phenomenon when minority product walk in rice field, and fix due to wheelspan, chassis is lower, cannot meet diversified line-spacing requirement.Chinese patent literature (CN203762119U) discloses a kind of adjustable pesticide spray truck of wheelspan being applicable to be with farmland, ridge, comprises vehicle body, wheel, between-wheel spacing adjusting device.Cannot walk on wheat ridge although this utility model solves existing pesticide spray truck, during operation, vehicle must walk among farmland, rolls the technical problem of crops during walking, can't adapt to the job requirements such as Different Crop growing height and surface humidity.

Summary of the invention

The object of this invention is to provide a kind of multi-functional running gear of rice cornfield that can adapt to Different Crop growing height, line-spacing and surface humidity.

The technical scheme realizing above-mentioned purpose is: the multi-functional running gear of a kind of rice cornfield, comprise 2 pontoons, be fixedly connected the elevator in pontoon and the power set that are connected on elevator, described elevator comprises the chassis be the level of state, be fixedly connected 4 support arms that can stretch vertically be arranged symmetrically with below chassis and the walking unit be in below center chassis position, and described walking unit is driven by power transmission shaft.

Further, described support arm comprises support arm outer tube and telescoping tube flexible vertically, and support arm outer tube and telescoping tube are equipped with the first locating hole for vertical telescopic every 3 ~ 10CM place.

Further, described chassis comprises underframe, embedded and be arranged symmetrically in inner 2 the lateral adjustments arms of underframe, and described lateral adjustments arm and underframe are provided with the second locating hole for transversal stretching every 3 ~ 10CM.

Preferably, pontoon cross section adopts V-structure.

Further, underframe can be established device such as spray medicine, broadcast application etc.

Further, unit of walking realizes vertical lift by crane vertical arm.

After adopting technique scheme, there is following beneficial effect:

(1) the present invention can adapt to the farmland operation demand of Different Crop growing height;

(2) the present invention can adapt to the farmland operation demand of Different Crop line-spacing;

(3) the present invention can adapt to the farmland operation demand of Different Crop growth surface humidity;

(4) cost of the present invention is low, wide market.

Embodiment

Below in conjunction with drawings and Examples, the present invention is further detailed explanation.

As shown in Figure 1-2: the multi-functional running gear of a kind of rice cornfield, comprise 2 pontoons 1, be fixedly connected the elevator 2 in pontoon 1 and the power set 3 that are connected on elevator 2, described elevator 2 comprises the chassis 2-1 be the level of state, be fixedly connected the 4 support arm 2-2 that can stretch vertically be arranged symmetrically with below the 2-1 of chassis and the walking unit 4 be in below 2-1 center, chassis, and described walking unit 4 is driven by power transmission shaft 5.

Further, as Figure 2-3, for adapting to the farmland operation demand of Different Crop growing height, described support arm 2-2 comprises support arm outer tube 2-2-1 and telescoping tube 2-2-2 flexible vertically, and support arm outer tube 2-2-1 and telescoping tube 2-2-2 is equipped with the first locating hole 2-2-3 for vertical telescopic every 3 ~ 10CM place.

Further, as shown in Figure 4, for adapting to the farmland operation demand of Different Crop line-spacing, described chassis 2-1 comprises underframe 2-1-1 and embedded and be arranged symmetrically in inner 2 the lateral adjustments arm 2-1-2 of underframe 2-1-1, and described lateral adjustments arm 2-1-2 and underframe 2-1-1 is provided with the second locating hole 2-1-3 for transversal stretching every 3 ~ 10CM.

Preferably, as shown in Figure 5, for effectively ensureing the craspedodrome stability of whole device, pontoon 1 cross section adopts V-structure.

Further, for playing the function of this device further, underframe 2-1-1 can establish device such as spray medicine, broadcast application etc.

Further, as shown in Figure 6, for adapting to the farmland operation demand of Different Crop growth surface humidity, walking unit 4 realizes vertical lift by crane vertical arm 4-1.

Operation principle of the present invention is as follows: pontoon 1 is provided with elevator 2, the telescoping tube 2-2-2 of support arm 2-2 can be moved along support arm outer tube 2-2-1 in the vertical direction by bolt, thus regulates the height of elevator 2 to adapt to the farmland operation demand of Different Crop growing height; 2 embedded underframe 2-1-1 inside that are arranged symmetrically in of lateral adjustments arm 2-1-2, in the crossbeam on chassis, by changing the relative position of bolt hole, can change the spacing of pontoon, to adapt to the farmland operation demand of Different Crop line-spacing; Crane vertical arm 4-1 adopts support arm 2-2 structure, can realize the mobile vertically farmland operation demand adapting to Different Crop growth surface humidity of walking unit 4.
