Abstract

The utility model discloses a multi-functional crawler-type farm tractor, which comprises a transmission box, on which an engine and a first drive shaft are mounted. At the two ends of the first drive shaft, a first driving wheel and a second driving wheel are mounted respectively. On the first driving wheel, a first crawler is mounted; in the first crawler, a first driven wheel and a second driven wheel are mounted. On the second driven wheel, a second crawler is mounted. In the second crawler, a third driven wheel and a fourth driven wheel are mounted. A first handle is mounted on the transmission box. When the tractor moves forward by the frictional force generated between the crawlers and the ground, as the crawlers can contact tightly with uneven ground, the torque output by the engine can be efficiently transformed into power for advancing, so energy can be saved. As the crawlers can contact tightly with uneven ground, the utility model can maintain balance and steady advancement when moving in an uneven farm field without being pressed by someone, can efficiently lighten the labor intensity of an operator. The utility model has the advantages of the low manufacturing cost and the easiness in using and installation.

Description

The agricultural machine of multifunction caterpillar

Technical field

The utility model relates to a kind of family farm machinery, exactly is the agricultural machine of a kind of multifunction caterpillar.

Background technology

At present, the power set that are usually used in weeding ground, plowing in agricultural production are hand tractors, and existing hand tractor all is to rely on engine to drive wheel, utilizes the frictional force on tire and ground to advance forward.But there is following problem in the existing hand steered machine that drags: 1, farmland surface is uneven, when people adopt existing hand tractor to weed ground, need firmly control hand tractor and make it keep balance, exist labour intensity more greatly, not easy-operating problem; 2, the tire of existing hand tractor can't closely contact with ground, often is prone to the situation of tyre slip, makes the moment of torsion of engine output can't change into the power that advances effectively, thereby causes energy waste.

Summary of the invention

The purpose of this utility model, provided the agricultural machine of a kind of multifunction caterpillar, it both can keep balance voluntarily, save manpower under the situation that nobody controls, the torque axis that can effectively engine be exported changes into the power that advances again, avoids the energy waste that causes because of tyre slip.

The purpose of this utility model is achieved through the following technical solutions: the agricultural machine of multifunction caterpillar, it has gearbox, engine is installed on the gearbox, first power transmission shaft is installed on the gearbox, the two ends of first power transmission shaft are installed first driving wheel and second driving wheel respectively, first crawler belt is installed on first driving wheel, first follower and second follower are installed in first crawler belt, second crawler belt is installed on second driving wheel, the 3rd follower and the 4th follower are installed in second crawler belt, first handle is installed on the gearbox.

For further realizing the purpose of this utility model realizing: the rear portion mounting and fixing support of gearbox by the following technical solutions.The rear portion of gearbox is positioned at the fixed mount top seeder is installed, seeder has sowing bucket, and first rotating shaft is installed in the sowing bucket, and an end of first rotating shaft passes outside the sowing bucket and is connected with first drive, first worm gear is installed in first rotating shaft, and the sowing bucket bottom is positioned at first worm gear below and offers first through hole.Dividing plate is installed in the sowing bucket, dividing plate is divided into first cavity and second cavity with the cavity in the sowing bucket, first rotating shaft is positioned at first cavity, first gear is installed in first rotating shaft, second rotating shaft is installed in second cavity, second gear and second worm gear are installed in second rotating shaft, offer groove on the dividing plate, and first gear and second gear are in the engagement of saturating groove place.Second power transmission shaft is installed on the gearbox, second drive is installed on second power transmission shaft, second drive and the first drive periphery are installed driving-belt.Guard shield is installed in the front portion of engine.

Good effect of the present utility model is: it is that the frictional force that produces by crawler belt and ground is when moving ahead, because crawler belt can closely contact with the farmland broken terrain, the torque axis that can effectively engine be exported changes into the power that advances, thereby can reach the good result of saving energy; Crawler belt contacts with ground closely, can make the utility model unmanned by the situation of holding up under, in rugged farmland, keep balance voluntarily, steadily advance, effectively reduce operator's labour intensity.The utility model also has cost of manufacture advantage cheap, easy to install and use.
