Description

The efficient peanut grain header

Technical field

The utility model belongs to agricultural machinery technological field, particularly a kind of peanut grain header that is used to gather in peanut.

Background technology

In known peanut harvesting technology, the harvesting of peanut is normally received by artificial the plane, and the peasant utilizes simple tools such as hoe or plough, and peanut seedling is dug out native face, slightly shakes out the earth of adhesion, and just shipment has been tedded.The work that whole results process is paid is many, and its labour intensity is big, and but very rate is low for effect, when the harvest season is met rainy weather, often because of gathering in the crops not as good as causing peanut to germinate in the ground even going mouldy, can not adapt to the harvesting of large tracts of land large-scale planting especially.

Summary of the invention

The purpose of this utility model provides a kind of rational in infrastructure, the efficient peanut grain header that the shovel of peanut can be dug, go soil, discharging to finish automatically continuously.

For realizing that the technical scheme that the purpose of this utility model is taked is: this peanut grain header comprises tractor-hitched peanut reaping apparatus, this device has a frame, upper rack is provided with power takeoff and is connected with intermediate transmission mechanism by the chain drive part, frame lower is provided with a peanut seedling conveying plant, the front end of this device is equipped with and is used for shovel in the deep soil and digs the perching knife of peanut seedling and cross the soil sieve, the cutter of dialling that can swing is equipped with in the top of crossing the soil sieve, the rear end of frame is provided with reason seedling sieve, the position, both sides be provided with can lift adjustment the ground-engaging wheel.

Described power takeoff is by power transmission shaft, drive sprocket and is used for drawing the belt pulley of getting power and controlling the running of this belt pulley from tractor constituting with the clutch that stops that clutch is controlled control stick by pull bar or stay cord with the movable type at tractor driving position and is connected.

Described intermediate gearing comprises the two-stage power transmission shaft, wherein be fixed with the eccentric wheel at the driven sprocket, intermediate drive wheel and the two ends that are connected with the drive sprocket of power takeoff on the one-level power transmission shaft, the intermediate drive wheel is taken turns with the second grade transmission chain on the secondary drive shaft by chain and is connected, and an end of secondary drive shaft is provided with driving pulley.

A described peanut seedling conveying plant is made of the uniform driven sprocket that is connected the tier pole on the carrier bar and is used to drive the drive sprocket of chain operation and plays the tension chain effect of driving chain, carrier bar, many, sprocket wheel adapter sleeve respectively is contained on drive chain wheel shaft and the driven chain wheel shaft, the drive chain wheel shaft is fixed with driven pulley, and be connected with driving pulley in the intermediate transmission mechanism by belt, an end of driven chain wheel shaft is provided with eccentric wheel.

Described group of cutter is toothrow shape structure, is connected with the eccentric wheel that is installed in drive chain wheel shaft two ends by connecting rod.

Described lifting ground-engaging wheel is provided with screw adjustments, can regulate the high and low position of road wheel by screw adjustments.

Described reason seedling sieve is provided with rotary balance staff, and bearing is crossed at the two ends of this balance staff and axle bed is connected with frame, and the end of balance staff is hinged by the eccentric wheel of driven chain wheel shaft in connecting rod and a fork and the peanut seedling conveying plant.

This peanut grain header is by agricultural tractor with small four wheels traction, and provides mechanically operated power by tractor.Before the work,, can adjust the digging depth of perching knife by regulating the high and low position of road wheel, during work, tractor-drawn peanut reaping apparatus advances along peanut ground ridge, and the perching knife that has the angle of inclination puts in the soil, peanut is routed up native face from root, and peanut seedling is along rising on the perching knife inclined-plane.Dial cutter and liken oscillating traverse motion to by the transmission of setting, swing clockwise can push peanut seedling on the conveying plant, puts in the time of counterclockwise.When conveyer belt was transported to the rear end with peanut seedling, peanut seedling lost support, falls under action of gravity, falls in the reason seedling sieve that is arranged on the conveying plant rear end, and reason seedling sieve is done oscillating motion under the effect of oscillating structural member, ceaselessly accepted and toppled over discharging peanut seedling.

Efficient peanut grain header according to such scheme is made has the following advantages:

(1) high efficiency, labour intensity is low.Peanut harvesting process all adopts the mechanization action to finish.

(2) harvesting quality height.This machine can be adjusted the suitable degree of depth that perching knife is cut the earth according to the peanut degree of depth of growing, and peanut is omitted in underground nothing, can not shovel the grating peanut fruit, and peanut earth dispels totally, and can reduce the loss of soil loam.

(3) rational in infrastructure, easy and simple to handle, the low cost of manufacture of use of this machine is connected with tractor, and it is convenient to set out, and flexibility is good.Use this machine to carry out the peanut harvesting, can effectively alleviate peasant's labour intensity, in time finish harvesting, no longer for there being weather cloudy and drizzly for days on end to worry.

(4) this grain header is specially adapted to the harvesting operation of large tracts of land peanut cultivation.
