Description

A kind of high speed corn combine

Technical field

The present invention relates to a kind of corn combine, is especially a kind of high speed corn combine.

Background technology

At present, the walking of the corn combine in society and operation all only share an engine, not only the power section structure of reaping machine is very complicated, and snapping part, crushed stalk part, fruit ear transport portion in results process, take off skin portion, impurities removal part and chassis running part various piece of grading and mutually restrict, influence each other, the power of engine is not in full use, not only can not ensure to gather in the crops quality, and being difficult to the high speed results realizing corn, production efficiency is very low.And engine seems very superfluous when road walking and transition, fuel consumption is large, and the use cost of user is high.

Summary of the invention

Object of the present invention overcomes above deficiency exactly, a kind of high speed corn combine is provided, it primarily of power section, snapping part, crushed stalk part, fruit ear transport portion, take off skin portion, impurities removal part, flexible silo part and chassis running part and to grade composition.It is characterized in that: power section adopts major and minor engine structure, and sustainer is mainly used in harvest operation, assistant engine is mainly used in walking and less important work; Crushed stalk part both can be arranged on the middle part of reaping machine, also front portion or the rear portion of reaping machine can be arranged on, it and the mounting point of reaping machine and the crankshaft axis of sustainer coaxial, sustainer is directly driven by drive pulley and driving-belt and pulverizes cutter shaft work; The elevator of fruit ear transport portion is widened, and make it adapt with the width taking off skin portion, take off the back lower place that skin portion is arranged on elevator top, elevator is carried the fruit ear come up to enter equably in the width direction and taken off skin portion; At the chopping of increase by a group below flail knife except trash roll in hetero moiety on elevator top, chopping flail knife is arranged on the front end of impurity discharging port, and directly backwards, the top at silo rear portion is provided with baffle plate in the outlet of impurity discharging port; Flexible silo part is primarily of compositions such as expansion bracket, telescopic oil cylinder, silo and overturning oil cylinders, wherein silo, overturning oil cylinder and expansion bracket form a whole, be arranged on the back upper place of reaping machine frame, stretching by telescopic oil cylinder, realize expansion bracket moving forward and backward in frame.

Good effect of the present invention: 1) major and minor engine at work separately independent, be independent of each other, even if also sufficient power can be provided for reaping machine under the harsh conditions such as sandy soil ground, slob, not only ensure that results quality, and operating speed also improves greatly, assistant engine work is only had in addition when road walking and transition, decrease fuel consume, reduce the use cost of user.2) crushed stalk part-structure simplifies the drive mechanism of stalk crasher, not only decreases the power consumption of stalk crasher, and reduces the manufacturing cost of maize harvesting machine.3) fruit ear transport portion structure efficiently solves the problem of skewness when fruit ear enters flaying machine, improves the operating efficiency of flaying machine.4) removal of impurities part-structure thoroughly solves existing corn harvester impurity-removing freely, susceptible to plugging problem.5) flexible silo part-structure not only efficiently solves existing reaping machine wheelbase and the long headland turn of appearance and size and to turn around inflexible problem, and loss when greatly reducing reaping machine operation.

Embodiment

The present invention is primarily of the composition (see Fig. 1) such as power section 1, snapping part 2, crushed stalk part 3, fruit ear transport portion 4, the part that strips off the skin 5, flexible silo part 6, chassis running gear 7 and impurities removal part 9.

Embodiment is as follows:

1, power section 1 adopts major and minor engine structure, wherein sustainer 10 is mainly used in harvest operation, only for snapping part 2, crushed stalk part 3, fruit ear transport portion 4, the part that strips off the skin 5 and impurities removal part 9 provide power, no longer for running gear provides power, eliminate the stepless speed regulation part of existing maize harvesting machine running gear complexity.Assistant engine 11 is mainly used in walking and less important work, as unloading, hydraulic pressure lift etc.During harvest operation two engines separately independent, be independent of each other, not only ensure that results quality, and operating speed also improves greatly.Only have assistant engine 11 to work when road walking and transition, sustainer 10 does not work, and greatly reduces fuel consume when road walking and transition, reduces the use cost of user.

2, crushed stalk part 2 both can be arranged on the middle part of reaping machine, also front portion or the rear portion of reaping machine can be arranged on, now crushed stalk part 2 is coaxial with the crankshaft axis of sustainer 10 with the mounting point of reaping machine, sustainer 10 directly drives pulverizing cutter shaft 12 to work (see Fig. 2) by drive pulley 15 and driving-belt 14, eliminate the intermediate transmission link that existing maize harvesting machine is numerous and diverse, improve the transmission efficiency of field-returning machine.The front portion of crushed stalk part 2 can also add collecting device 16, collecting device 16 is distributed between the two ends, left and right of crushed stalk part 2 and each group pulverizing flail knife 13 (see Fig. 3), and during work, the crops straw of lodging is propped up and drawn pulverizing flail knife 13 place in and pulverizes by collecting device 16.

3, the main distinction of the conveyer of fruit ear transport portion 4 and the use of existing maize harvesting machine is: widened by the elevator 21 of fruit ear transport portion 4, it is made to adapt with the width of the part 5 that strips off the skin, elevator 21 carries the fruit ear come up to enter the part 5 that strips off the skin equably in the width direction, ensure that giving full play to of flaying machine operating efficiency; At the chopping of increase by a group below flail knife 23 except trash roll 22 in hetero moiety 9 on elevator 21 top, chopping flail knife 23 is arranged on the front end of impurity discharging port 24, the outlet of impurity discharging port 24 directly backwards, the cauline leaf of being discharged by trash roll 22 and blower fan 26 during work is after chopping flail knife 23 is pulverized, directly discharged backwards by impurity discharging port 24, thoroughly solve existing corn harvester impurity-removing not smooth, susceptible to plugging problem.The broken cauline leaf of discharging to prevent impurity discharging port 24 enters silo 33, can install baffle plate 25 (see Fig. 4) above silo 33 rear portion;

4, flexible silo part 6 is primarily of compositions such as expansion bracket 31, telescopic oil cylinder 32, silo 33 and overturning oil cylinders 34, wherein silo 33, overturning oil cylinder 34 and expansion bracket 31 form a whole, be arranged on the back upper place of reaping machine frame, stretching by telescopic oil cylinder 32, realizes expansion bracket moving forward and backward in frame.Like this when carrying out harvest operation, telescopic oil cylinder 32 shrinks, silo 33 moves on to the below of debarker, fruit ear and the kernel direct of results tap into into silo 33, can not drop to the ground, not only solve the problem that existing maize harvesting machine machine shape size is long, and loss when greatly reducing reaping machine operation.When carrying out unloading operation, telescopic oil cylinder 32 first extends, and expansion bracket 31 and silo 33 are moved on to the rear (see Fig. 5) of debarker or conveyer, then overturning oil cylinder 34 extends, silo 33 is overturn, grain is discharged to (see Fig. 6) on transport vehicle

5, the transmission of chassis running gear 7 can be various ways, and both can be belt transmission+mechanical changeover form, also can be hydraulic pressure electrodeless variable-speed+mechanical changeover form, can also be all-hydraulic electrodeless variable-speed form; Running gear both can be wheeled, also can be crawler type; When running gear is wheeled, both can be two-wheel drive, also can be four wheel drive.
