Abstract

The invention aims at providing a small-sized multifunctional combine-harvester which is used for achieving the purpose that the combine-harvester can perform more use functions. The small-sized multifunctional combine-harvester comprises a combine-harvester main body including a gearbox assembly, wherein the gearbox assembly is suspended at one end part of the combine-harvester main body; a suspended part is controlled to rise and descend by a gearbox lifting oil cylinder which is located on a back cross beam, so as to drive the tail part of a gearbox to move up and down; meanwhile, a connecting frame connected other agricultural implements is fixed on the back cross beam. As the connecting frame convenient to be connected with the other agricultural implements is arranged on a power output mechanism of the combine-harvester and the combine-harvester is connected with the other agricultural implements by belt wheels or gears, the combine-harvester obtains various functions and the functions of the various functions are greatly increased. Meanwhile, in order to perform various functions of the combine-harvester, a design with smaller integral size is needed; therefore, the integral balance can be reduced and the problem that the integral balance can be reduced is preferably solved through the adoption of a balancing shaft suspending wheel.

Description

Multi-functional small combine harvester

Technical field

The invention belongs to agricultural machinery technological field, particularly the improvement of combine.

Background technology

Combine belongs to the higher agricultural machinery of value, but is no more than one month service time, so that the user is difficult to bring into play larger benefit.Simultaneously, the existing general type of combine is larger, and drive adopts the single shaft independent suspension, is adapted at more smooth field operation, runs into the field that ditch is arranged, and tumbles easily.

Summary of the invention

The present invention aims to provide a kind of Multi-functional small combine harvester, can bring into play the purpose of more use functions to satisfy combine.

Specifically, Multi-functional small combine harvester, has the combine main body, comprise transmission assembly in the combine main body, its transmission assembly hangs on end of combine main body, and the suspension position is moved up and down by the hydraulic jack control lifting drive speed changer afterbody that is positioned on the rear cross beam; Be fixed with for the link that connects other farm machinery on the rear cross beam simultaneously.

Ceding of Taiwan base plate in the described combine main body is the arc that raises up.

Drive assembly in the described combine main body is divided into front group and rear group, and every group be made of two pairs of drives, connects by trunnion shaft between two pairs of drives, and trunnion shaft hangs and is fixed on the chassis overhang.

The present invention uses belt pulley or gear to be connected with other farm machinery owing to be provided with at the combining power take-off mechanism and be convenient to the link that is connected with other farm machinery, and realization combine a tractor serves several purposes has increased the function of combine greatly.Simultaneously, for satisfying the combine a tractor serves several purposes, need to adopt the less design of overall dimensions, like this, whole machine balancing will descend, and adopts the trunnion shaft suspension sheave that mode has well been solved this problem.

Embodiment

As shown in Figure 1 and Figure 2, Multi-functional small combine harvester, has the combine main body, comprise transmission assembly 1-30 in the combine main body, it is characterized in that transmission assembly 1-30 hangs on end of combine main body, and the suspension position is moved up and down by the speed changer hoist cylinder 1-32 control lifting drive speed changer afterbody that is positioned on the rear cross beam; Be fixed with for the link that connects other farm machinery on the rear cross beam simultaneously.Be equipped with on the power take-off among the transmission assembly 1-30 can with the power output gear of other farm machinery power input gear engagement.Also can be equipped with on the power take-off among the transmission assembly 1-30 and be convenient to the belt pulley that is connected with other farm machinery power input wheel.。Be used for other farm machinery by drawing original grain header power, enlarged the grain header scope of application, greatly reduce use cost, other farm machinery are rotovator or sower or cracker or hay cutter.In order to use season in non-harvesting, adopt the less design of overall structure, need to reduce grain header overall dimensions and power, therefore, original combine structure has been done following change: 1, the ceding of Taiwan base plate in the combine main body is the arc that raises up.Like this, also can charging under less power fast, loss be few.2, the supporting wheel assembly 1-1 in the combine main body is divided into front group and rear group, and every group be made of two pairs of wheels, connects by four-wheel trunnion shaft 1-6 between two pairs of wheels, and four-wheel trunnion shaft 1-6 hangs and is fixed on the chassis overhang 1-5.Hang drive by trunnion shaft, whole machine balancing is good, and trafficability characteristic is good, and the little climbing capacity powerful of volume is many, uses the small pieces field, and can be in complex-terrain work such as mountain areas.Wheat rice harves, millet straw pulverizing recovery, short-distance transport be can satisfy, ground, sowing plowed, revolve.

Among the present invention, combine is except above-mentioned change, and basic structure does not change, and therefore is not described in detail its structure here.

Operation principle

Advance operation results: straw shift wheel is with the drag on ceding of Taiwan and cut off by blade of cereal, cereal is delivered to plate tooth case mouth by helix drum, the Chain plate tooth transmits cereal into wheat scourers again, enter cracker through millet straw after the wheat scourers threshing by wheat scourers left side straw outlet, can directly be sprinkling upon geography or pack recovery after millet straw is pulverized by cracker for industry such as papermaking.Then grain at first enter screen box through the scalping screening, by the triangular scraper plate grain transmitted into the dusting cover face, and sieve shakes back and forth to cereal postsearch screening.Grain is leaked down simultaneously by sieve and by the wind-force of sieve inferoanterior blower fan cavings foreign material in the grain etc. is stayed on the compass screen surface, and sieve continues shake the cavings foreign material are got rid of.Fall at the bottom of the screen box after the screening of (blower fan can be adjusted air force as required) grain, pack by stirring to take turns to be sent to upper grain device and to send the cereal rising to bagger by upper grain device chain scraper.Front header part is by the HYDRAULIC CONTROL SYSTEM lifting.Machine rear-mounted position moves up and down the speed changer afterbody and drives agricultural equipment and adjusted up and down by the hydraulic jack control lifting that is positioned on the rear cross beam.The transmission operating system adopts flexible cord to connect.

Scooter is 20 kilometers/hour during the machine, saves time, saving of labor, saving economical energy resources.Outstanding function is exactly front results, rear sowing, carries out simultaneously.Harvest season later can also be pulled down harvesting part, uses that main frame carries out ploughing and weeding, ploughs, revolves, sowing etc.; Also can carry out the short-distance transport operation.
