Description

Peanut harvester {Peanut harvester}

The present invention relates to a peanut harvester, and more particularly, a peanut capable of automatically performing both a harvesting operation for harvesting a peanut crop planted in the ground and a threshing operation for separating the stem and the crop from the harvested peanut crop. It is about the harvest season.

In general, the cultivation of crops has become large in accordance with the recent mechanization trend of agriculture, various harvesters are used for harvesting crops, and peanuts must also be cultivated and harvested in large quantities.

However, since peanuts are grown in the ground, unlike other crops that can be harvested on the ground, such as rice, there is a difficulty in harvesting what is buried in the soil.

In addition, since the harvesting time of peanuts is short, if the harvest is not done in a timely manner, there is a disadvantage that the harvest loss and the value of the product decrease.

And, as described above, since peanuts are harvested by digging out what is buried in the soil, peanuts planted in the ground are harvested by digging the ground to a certain depth and pulling the stem. Harvesting peanuts grown in large quantities by hand is impossible, so we have no choice but to rely on the peanut harvester.

The conventional peanut harvester has been proposed in Korean Patent Registration No. 10-0288132 (name: peanut harvester with a selection system, hereinafter referred to as'prior technical literature').

In this prior art document, a means for pulling up the stem on the front side and a peanut stem and root portion grown in multiple rows in multiple rows by means of at least one gulch blade are excavated on the ground with soil, and the peanut stem is gripped to In the provided with a means for feeding to, and provided in a direction to be conveyed to the rear by being bitten by the conveying chain, the soil shaving means for crushing and shaking off the soil mass of the peanut root portion; A feeder having two shafts disposed adjacent to each other with feed blades so as to scatter and separate the peanuts from the roots of the peanuts that are transported in a state where the soil is shaken by the dirt whisking means; A conveying means for transporting the peanuts separated from the barrel to separate and select twigs, etc., which have fallen together when the peanuts are separated from the barrel and separated from the shells; A vibrating screen for separating twigs and vinyl of the peanut stem conveyed by the conveying means, a brushing device installed under the vibrating screen to remove soil from the peanut shell, and a peanut from the brushing device to a collector. Including, separating peanuts together with soil hairs by digging roots from the ground, including; inclined screens to be transported and picking means installed under the inclined screens to separate twigs and dirt dust by blowing force to collect only peanuts. And a peanut harvester configured to perform the peanut harvesting operation by consistently and automatically processing the selection operation.

However, in the conventional peanut harvester, the peanut stems and roots cultivated on the ground are excavated above the ground, and the excavated peanut stems are grasped and transported by a transport chain. Due to the bottleneck flowing between the two conveying chains, there is a possibility of malfunction, such as a large load and a stoppage of operation, and as a result, the harvesting operation of peanuts proceeds slowly, resulting in poor harvesting efficiency of the peanuts.

In addition, in the conventional peanut harvester, since the gulchwi blade for gulching peanuts from the ridge is maintained in a fixed state, there is a problem that the efficiency of oystering operation is lowered when harvesting peanuts from the ridge of various heights.

In addition, by the rotation of the lower connection shaft 230 as described above, the conveyor belt 310 at the rear of the first transfer chain 270 is transferred from the front to the rear and rotated when viewed from the upper surface thereof.

And, when the upper drive shaft 220 rotates, the upper drive shaft 220 and the bevel gears 226 and 321 are connected as both the transfer shafts 320 are rotated in opposite directions, both transfer shafts 320 and the bevel gear The rear connection shafts 330 connected as 322 and 331 are also rotated in opposite directions.

By the rotation of the rear connection shaft 330, the second transfer chain 340 is also rotated in opposite directions, and a pair of output shafts connected as both rear connection shafts 330 and bevel gears 331 and 351 respectively ( 350) As also rotated in the opposite direction, both threshing rotation shafts 410 are rotated in a direction facing each other by the pulley 352 of each output shaft 350 and the pulley 413 connected as a belt 353.

That is, by the rotation of the rotation shafts 410 for both threshing, the threshing shafts 412 on both sides are rotated clockwise, and the threshing shaft 412 on the left is rotated clockwise, as seen in FIG. While rotating in the counterclockwise direction, the peanuts are shaken toward the lower conveyor belt 310 and threshed.

In this way, when the peanut harvester 100 is moved by the tractor in a state in which the peanut harvester 100 is operated by receiving the power of the tractor, the gulchwi blade 290 moves the peanut above the ground in the ground where the peanut is planted. You will be drowned.

The peanuts gulch in this way are introduced to the upper surface of the gulchwi blade 290 through the front end of the main body 110 of the peanut harvester 100, and the stems of the introduced peanuts are rotated in opposite directions by a certain amount on a pair of harvesting blades. It is held and sent to the rear first transfer chain 270 and transferred.

In this process, the root portion of the peanut crop that is transferred to the first transfer chain 270 is removed by first shaving off the soil by the soil hair removal shaft 281 rotated behind the gulch blade 290, and then the first transfer chain It is transferred to 270.

The peanut stems transferred to the first transfer chain 270 are held as they are between the unit links of the first transfer chain 270 in contact with each other, and are transferred to the second transfer chain 340 at the rear of the main body 110. .

Thereafter, the peanut stem transferred to the second transfer chain 340 is held between the second transfer chains 340 and transferred to the rear of the body 110, and in this process, the root portion of the lower end of the peanut stem is The soil is secondarily removed by being shaken downward by both threshing shafts 412 rotated under the conveying chain 340, and the tang beans are removed from the stems and fall like soil on the conveyor belt 310.

Then, the peanuts and soil are transported to the rear end of the main body 110 by the conveyor belt 310 and introduced into the discharge tray 420, and the bottom surface of the discharge tray 420 is provided in a mesh shape, so that the peanuts 420) is filtered and stored, but the soil falls onto the ground through the mesh-shaped bottom surface.

And, the peanut stem from which the peanuts are separated is continuously conveyed and discharged to the rear side of the main body 110 by the second conveying chain 340, and discharged respectively provided at the top and bottom of the second conveying chain 340 in this process. The guide 341 is guided in a state in which sagging of the transported peanut stem is prevented, thereby inducing smooth discharge of the peanut stem.

Although the present invention has been described in detail through specific examples, this is for explaining the present invention in detail, and the present invention is not limited thereto, and those of ordinary skill in the art within the spirit of the present invention It is clear that modifications or improvements are possible.

All simple modifications to changes of the present invention belong to the scope of the present invention, and the specific scope of protection of the present invention will be made clear by the appended claims.
