The utility model is characterized in that the back surface of a gear box of a light jeep is provided with a transfer case which drives a screw blade propeller; one transfer case is added on a rear axle which is used for driving the rear axle and a hydraulic device; the front and the back of the utility model are provided with a power output shaft, a tow device and a bottom, wherein, the bottom which can be lifted is provided with the screw blade propeller. When the utility model drives on land routes, the utility model which is a jeep can tow a trolley wagon; when the utility model works in fields, the utility model which is a tractor can tow matching equipment, such as a plough, a harrow, a rice transplanter, a cultivator, a harvester, etc. The utility model is suitable for jobs of water tillage, and the rotation of the water tillage and dry tillage of various paddy fields in plains, hills, and mountainous areas.
Description
The utility model relates to a kind of agrimotor, especially the jeep trac..
China paddy rice producing region, the natural conditions complexity, varieties of plant is various.But, has only the branch of water work and dry farming with regard to farming technique.The paddy field dry farming, general trac. still can be brought into play drawbar efficiency.Water uses water as, and general trac. just is difficult to the performance drawbar efficiency.This situation has caused the paddy field soil dynamics problem.From the paddy field soil dynam, existing various paddy fields engine can be divided into the system of following three power.
1, friction force system, i.e. the weight of trac. dependence self and traveling gear and ground-surface fricative adhesive ability are obtained tractive force.General wheeled track type tractor all belongs to this power system.Paddy field water is ploughed, and this power system is difficult to the performance drawbar efficiency.Especially paddy field with ponded water in winter, the deep paddy field of this class hardcore, land reclaimed from a lake can't enter farming at all.
2, engagement force system, promptly engine relies on the engagement of own wt and traveling gear and soil, relies on the anti-shear ability of the soil that is engaged with to obtain tractive force.As pressing the dress impeller on wheeled and the walking tractor, the boat tractor on ground such as Hubei, Hunan all belongs to this power system.Manoevreability, the efficient of this power system are all very poor.
3, walking and rotary tillage split power system, and promptly trac. removes self walking, drives the rotovator rotary tillage from the power take-off shaft horsepower output, but the quality of rotary tillage is always not as good as the quality of ploughing.And, because the own wt of trac. also can't enter farming in the deep paddy field of hardcore.
In a word, paddy field water is done, friction force system and engagement force system, and the equilibrium problem between the application force of very difficult solution traveling gear and the antagonistic force of soil is difficult to obtain drawbar efficiency preferably; Walking and rotary tillage split power system, and its rotary tillage quality is not as good as the ploughing quality.And above-mentioned three power are the farming problem in the deep class paddy field of hardcore that all can't solve.So, also there is not a kind of efficient height so far, quality is good, can adapt to the trac. that all kinds of paddy fields are carried out water farming industry and can be carried out rice field-upland field rotation again.
The patent name that I once obtained the authorization: multi-functional paddy field trac., the patent No.: ZL92236178.9.Attempt addresses the above problem, but finds in trial-production and process of the test: water is done to be difficult to exchange and use simultaneously with dry farming two cover mechanisms; Water is done and dry farming two cover driving system and operating system more complicated, is difficult to unite two into one.
The purpose of this utility model is a kind of jeep trac. that proposes for the shortcoming that overcomes above-mentioned technology existence.
The purpose of this utility model is achieved in that friction force system is combined with the principle of spiral power system, designs a kind of jeep trac., and the off-road capability of jeep (Jeep) car and the tractive property of trac. are all arranged simultaneously; Back at a kind of change speed gear box of light-duty jeep increases an auxiliary gear box, drives the helicallobe propelling unit and carries out rotary tillage, advances and turn to, and it is to plough and other supporting with it work tool with rotary tillage traction ploughing, rake; An auxiliary gear box is arranged on back axle, drive hydraulic gear, can make and the angle of rake bottom of helicallobe and draw gear lifting are housed freely, when farm work, three kinds of functions are arranged, the one, the helicallobe propelling unit is dropped to below the wheel, only use the helicallobe propelling unit to carry out operation; The 2nd, helicallobe propelling unit and wheel complement each other and use simultaneously; The 3rd, the helicallobe propelling unit is risen, only use the wheel subjob; Power from former and later two auxiliary gear box output front and back power take-off shafts; It has comprehensive operating system; There is a hook back, can pull trolley; Use as jeep at ordinary times, assemble the operation of going to the field again of helicallobe propelling unit and outfitting tool thereof during operation, use as trac..
The utility model compared with prior art has following advantage.
1, the utility model is applicable to that all kinds of paddy fields carry out that water is ploughed and the rice field-upland field rotation operation, especially is suitable for deep paddy field of sub-hardcore such as winter water in field, land reclaimed from a lake, waterlogged plot etc., can give full play to drawbar efficiency;
2, the trac. of friction force system and engagement force system, the power of its output all has the ratio problems of a useful work and idle work, the power of the utility model output, be defeated by the helicallobe propelling unit, drive it and carry out the rotary tillage operation, up to towage, all be useful work, the degree of utilization of power unprecedentedly improves;
3, the utility model is with rotary tillage traction ploughing, plough with the rotary tillage brag rake, this farming pattern has been brought up to a brand new level with intensive cultivation, for the g and D of paddy has been created good condition, not only can raise labour productivity, and can improve fertility, increase yield per unit area;
4, body own wt of the present utility model is light more, and the efficient of traction is good more, and it can reduce the body own wt as much as possible, with reach in light weight, volume is little, maneuverability, therefore, it can reduce raw materials consumption greatly;
5, give full play to the special use of power machine and the function of comprehensive application, both had the function of jeep, had the function of trac. again.
