Description
Technical field
The utility model relates to a kind of farm machinery, especially relates to a kind of multifunctional agricultural machine.
Background technology
Rice transplanter is one of the most frequently used mechanism in agricultural mechanism, and field cleaning device (mainly referring to fertilizer distributor, vehicle-mounted sprayer) also is widely used.The Chinese patent that is CN101611668 as publication number discloses a kind of fertilizer distributor, and publication number is that the Chinese patent of CN102450131 discloses a kind of agricultural fertilizer applicator.Existing rice transplanter and field cleaning device are two independently equipment, and cost is higher.Because the characteristics of transplanting work have determined its frame the end of than, and the field cleaning device is generally to grow to higher just use afterwards crop, thus its frame need higher, the structure on frame as far as possible can not with the crop interference.Therefore, existing rice transplanter and field cleaning device can not be realized on an equipment.
In addition, existing rice transplanter use machine driving without exception, this kind of drive are with the accuracy of its transmission, and ripe technology is well received.But its complicated transmission mechanism has restricted rice transplanter to be developed to multifunction, has also promoted its maintenance cost.
Summary of the invention
The utility model is mainly to solve arriving mutually independently of the existing rice transplanter of prior art and field cleaning device, cost is higher, and the frame of existing rice transplanter is the end of than, and the technical problem that the bracket height of field cleaning device is had relatively high expectations, provide a kind of and can be respectively used to rice transplanter and field cleaning device, and the double-deck vehicle frame of field operating vehicle simple in structure, easy to use.
above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of double-deck vehicle frame of field operating vehicle, it is characterized in that it is made of the operation frame that is used for the walker of road wheel being installed and being used for installation exercise equipment, operation frame is located at the upside of walker, and be connected by an elevating mechanism between walker, described walker is made of two of left and right walking beam, described elevating mechanism comprises several lifting columns, this lifting column is evenly distributed on two walking beams, described operation frame is provided with the bindiny mechanism that can be respectively be connected with low level implement and high-order homework machinery.When operation frame connects rice transplanting mechanism (or other need at the equipment of lower operation), operation frame is in lowest order; When operation frame connects field care institutions vibrations (or other needs the equipment of operation aloft), when the operation such as applying fertilizer, because this operation is generally all carried out to certain phase in plant growth, the plant height that is in this moment is higher, and the height of chassis above ground during rice transplanting can not meet the demands.Just need operation frame to raise under the effect of elevating mechanism.Only have the walking beam of left and right sides due to the walker of the technical program, there is no crossbeam, in use, the walking beam of left and right sides is in the gap of crop, and not with the crop interference, therefore, the height of operation frame has determined the effective depth of this vehicle frame.The Height Adjustment of operation frame by lifting column stretch complete.
As preferably, described lifting column is lifting hydraulic cylinder, and each walking beam is provided with former and later two described lifting hydraulic cylinders, and this hydraulic cylinder is connected with fluid power system.Hydraulic cylinder is as lifting column, and it is easy to use, the power arrangement convenience.
As preferably, the power of described hydraulic-driven system is provided by electric hydraulic pump or hydraulic hand-pump.Adopt electric hydraulic pump to have easy to use, simple to operate is preferred, but because the frequency of high-low-position conversion of the present utility model is very low, in order to reach the saving cost, reduces the purpose of the fault rate of equipment, and the utility model also can adopt hydraulic hand-pump.
As preferably, the rear and front end of the left and right sides of described operation frame is respectively equipped with connecting hole on fixed head, the rear and front end of the both sides walking beam of described walker also is respectively equipped with connecting hole under fixed head, under the fixed head in each orientation on the fixed head of connecting hole and corresponding orientation connecting hole corresponding.When operation frame was in the working depth of field care institutions vibrations, more firm for making its structure, the technical program was provided with the upper and lower connecting hole of fixed head, by the upper and lower connecting hole of this fixed head, fixed head is set, and connected operation frame and walker.
