Abstract

The utility model discloses a corn harvester. The existing corn harvesters need manual opening of a straw lodging passage before use, thus being ultra-inconvenient. Aiming at solving the technical problem, the corn harvester comprises guide plates, a disc cutting knife, a straw passage arranged at one side of a tractor, and a straw conveying mechanism. The upper end of the straw passage is inclined to the tractor and consists of an inner guardrail and an outer guardrail in parallel, and the front end of the outer guardrail is fixed on a fixing arm under the disc cutting knife; the running direction of a belt or a chain in the front side of the straw conveying mechanism points to the straw passage, and a deflector rod is arranged on the front edge of the belt or the chain; and the guide plates are provided with a vertical ridging rod, an elastic tentacle is arranged horizontally on the ridging rod, and the disc cutting knife is arranged between the two adjacent guide plates. As the upper end of the straw passage is inclined to the tractor, after being moved out from the straw passage, the straws naturally lodge on the empty ground behind the tractor under the effect of self gravity.The corn harvester is widely applicable to the harvesting of corns or other straw crops.

Description

Corn picker

Technical field

The utility model relates to a kind of farm machinery, particularly a kind of corn picker.

Background technology

Existing corn combine, harvesting, threshing, 3 work of straw chopping and returning are carried out simultaneously, have alleviated people's labour intensity, and still, there is breakage in various degree in gained corn seed, should not use as seed; Maize straw is important animal feeding-stuff in rural area and fuel, and directly chopping and returning causes very big loss to the peasant.This also is the reason that existing corn combine is not widely used in agricultural production.Its harvested stalk of existing corn picker is swung to a side, for preventing to be pressed onto other crops, must manually open stalk lodging passage before using, and is not suitable for the requirement of agricultural modernization; For long and narrow field, because after manually opening stalk lodging passage, milpa to be cut remains little, and is not suitable for more.

The utility model content

The technical problem of the confidential solution of the utility model reaping corn is the above-mentioned defective that how to overcome prior art, and providing a kind of does not need manually to open stalk lodging passage, and is suitable for the corn picker in long and narrow field.

For solving the problems of the technologies described above, the utility model corn picker is installed in the tractor front side, comprises guide plate, mechanical shoulder cut-off knife, stalk passage and stalk conveying mechanism.The stalk passage is arranged on a side of tractor, and the upper end tilts to tractor, is made up of parallel inside and outside guardrail, and outer guardrail front end is fixed on the fixed arm of mechanical shoulder cut-off knife below; The stalk conveying mechanism is arranged on the top of mechanical shoulder cut-off knife, is made of horizontally disposed belt pulley set or chain wheel set, and wherein the rotation direction of the belt of front side or chain points to the stalk passage, and the leading edge of its belt or chain is provided with driving lever; Guide plate is provided with vertical branch Gansu Province bar, elasticity tentacle before being horizontally disposed with on this minute Gansu Province bar, and mechanical shoulder cut-off knife is arranged between 2 adjacent guide plates.So design, corn to be cut is under the guiding of guide plate, the inboard of elasticity tentacle before at first being squeezed into, cut by mechanical shoulder cut-off knife then, the maize straw that is cut off moves to the stalk passage under the drive of belt or chain and driving lever thereof, after entering the stalk passage, because described stalk passage upper end tilts to tractor, so advancing along with corn picker, with respect to grain header, stalk moves obliquely backward, after stalk moves out the stalk passage, is subjected on the vacant lot after self gravitation influences nature lodging tractor.Can not be pressed onto other crops, be specially adapted to long and narrow field.

As optimization, the top of described outer guardrail also is provided with height greater than two meters fixed arm.So design, outer guardrail is more firm, and can not influence stalk and do to move with respect to tractor.

As optimization, described stalk conveying mechanism is made of horizontally disposed belt pulley set, and its belt is active band, this active with on shank of bolt protrude in this active band.So design, outstanding shank of bolt can the double as driving levers, are convenient to make.

As optimization, the front and back end of described outer guardrail exceeds interior guardrail, and outer guardrail rear end is provided with back elasticity tentacle, the other end of this back elasticity tentacle and the back end in contact of interior guardrail.So design, stalk is assembled bunchy in the stalk passage after, back elasticity tentacle bend by pressure, the stalk bunchy lodges behind tractor, is convenient to follow-up work.

As optimization, described stalk passage is arranged at the left side of tractor, the right side of corn picker is provided with drive pulley, this drive pulley links to each other by the pulley groove on the flywheel of belt and tractor, the central shaft of this belt pulley is positioned at the below of mechanical shoulder cut-off knife, and being fixed with the bevel gear that equates with the mechanical shoulder cut-off knife number, another fixing bevel gear meshes for each bevel gear and mechanical shoulder cut-off knife concentric; The central shaft that the center of the belt pulley of described stalk conveying mechanism or the center hinge of sprocket wheel are connected to the mechanical shoulder cut-off knife of crops stalks both sides prolongs on the axle.So design is simple in structure, and running is reliable.

As optimization, described mechanical shoulder cut-off knife is four, and described belt pulley set is two.So design, structure are compact more, and it is more reliable to turn round, and are fit to 12,15,18 or 20 horsepowers of tractors and use.

After adopting technique scheme, use the utility model corn picker, the maize straw of harvesting is placed on the vacant lot behind the tractor by neat, bunchy automatically, is convenient to peasant's harvesting corn stalk and corn ear.Be applicable to the harvesting of corn, paddy rice or other crops stalks.It has, and cost is low, and making is simple, and assembling is quick, and is efficient when using the time, can reduce labor intensity, and can shorten the advantage of harvesting time again.

Below in conjunction with the drawings and specific embodiments the utility model corn picker is described further:
