The third gear 3b of the first interlocking gear portion 31 is engaged with the fourth and fifth gears 41a and 43a of the transferring portion 40 so that the first and second shafts 41 ) 43 can be rotated at the same time. In this case, the first shaft 41 and the second shaft 43 rotate in opposite directions to each other.

1 to 4, the conveying unit 40 according to the present invention is rotatably connected to the first interlocking gear portion 31 of the first gear box 30 to rotate the cornice CS in the rearward and downward directions The corn barrel CS is transported so that the crushing section 50 can finely crush the corn barrels CS from which the corn C has been removed by the cutting section 60. [

The transfer unit 40 for this purpose is constituted by a plurality of shafts, that is, a first shaft 41 and a second shaft 43, and the first shaft 41 is disposed at an upper portion of one side of the second shaft 43. A fourth gear 41a and a fifth gear 43a are provided at the rear ends of the first and second shafts 41 and 43. The fourth gear 41a and the second shaft 43a of the first shaft 41, The fifth gear 43a of the first driven gear portion 43 is engaged with the third gear 3b of the first interlocked gear portion 31 and is rotated at the same time.

The first shaft 41 and the second shaft 43 of the transfer unit 40 are provided with the transfer screws 45 and the transfer screws 45 of the respective shafts are rotated in opposite directions. In this case, the feed screw 45 of the first shaft 41 and the feed screw 45 of the second shaft 43 rotate inward to mutually push down the corn caster CS while transporting it backward. In other words, the corn cage CS can be transported downwardly while entering between the respective transporting screws 45, and finely crushed by the crushing unit 50 to be described later.

1 to 4, the crushing unit 50 according to the present invention is disposed below the conveying unit 40 and serves to finely crush the cornice CS in cooperation with the main shaft 20 .

The crushing unit 50 for this purpose is rotatably coupled to the harvester at one end and a fourth pulley 53 at the other end. The fourth pulley 53 of the crushing section 50 is connected to the third pulley 23 of the main shaft 20 by the belt B and is rotated.

A plurality of blades 51 are connected to the shaft of the crushing unit 50 to finely crush the cornice CS which the conveying screw 45 of the conveying unit 40 pushes downward.

The cutting portion 60 for this purpose is connected to the lower shaft of the cutter 61, and the ninth gear 63 is mounted at the lower end of the shaft. In this case, the rotation of the cutter 61 is transmitted through the first shaft 41 of the transferring section 40 and the second interlocking gear portion 71 of the second gear box 70. The third shaft 47 is accommodated in the transfer screw 45 of the transfer unit 40 and the third shaft 47 is connected to the first shaft 41. [ And a sixth gear 47a is provided at the front end of the third shaft 47. [

The second gear box 70 is disposed below the cutter 61 of the cutout portion 60 and has a second interlocking gear portion 71 therein. (71a) and an eighth gear (71b). The seventh gear 71a of the second interlocking gear portion 71 is engaged with the sixth gear 47a of the third shaft 47 and at the same time the eighth gear 71b of the second interlocking gear portion 71 Is engaged with the ninth gear (63) of the cut portion (60). The second interlocking gear portion 71 is rotated by the rotation of the first shaft 41 and at the same time the cutter 61 of the cutting portion 60 is rotated to cut the corn C from the cornice CS, .

In this case, the cutting of the corn C by the cutter 61 of the cutting portion 60 is possible because the feed screw 40 of the feeding portion 40 pushes the corn caster CS backward and downward, Falls in a direction opposite to the moving direction of the harvester. When the corn crossover CS collapses, the cutting operation of the corn C can be smoothly performed by the horizontally arranged cutter 61.

A cover 65 for covering the cutter 61 is provided at the upper portion of the cutter 61 of the cutout portion 60 to prevent the fragment from being scattered due to breakage of the cutter 61, It is possible to originally seal the contact when it is close to the cutter 61.

On the other hand, a receptacle 90 is provided on the opposite side of the cutter 61 of the cutting portion 60 to collect the corn C cut by the cutter 61 of the cutting portion 60. Therefore, the corn C cut by the cutter 61 of the cutting portion 60 can be discharged to the receptacle 90 and collected.

As shown in FIGS. 1 and 4, the guide bracket 80 for guiding the corn CS to the conveying screw 45 of the conveying unit 40 is provided.

The guide brackets 80 according to the present invention are configured as a pair so that the spacing width becomes narrower toward the rear. That is, the front end separation width of the guide bracket 80 is relatively wider than the rear end separation width to facilitate entry of the corn cage CS, and the corn cage CS that has entered the guide bracket 80 moves backward The separation width is narrowed and naturally collected by the conveying screw 45 of the conveying unit 40, so that the harvesting operation can smoothly proceed.

The harvester according to the present invention is operated by a tractor, a tiller or a prime mover (1). In this case, a plurality of wheels (2) are provided in the lower part for smooth movement.

In addition, it is preferable that the handle 3 is provided on the upper part of the harvester so that the operator can grip and move the handle 3 when the harvester is separated from the tractor, cultivator or prime mover 1.

The prevention plate 5 is provided on both sides of the bottom of the harvester 50, that is, on the side of the crushing unit 50. When the blade 51 of the crushing unit 50 is in contact with the ground or the stone, The safety of the operator can be corrected by blocking the scattering of the stones. Also, the blades 51 may collide with the ground and the stones and may be damaged. Even when the broken pieces of the blade 51 are scattered, the prevention plate 5 prevents the blades 51 from being damaged, thereby securing safety.

The corn mathematical machine according to the present invention configured as described above is configured such that the power transmitted from the power transmitting portion 10 is transmitted through the main shaft 20 and the first gear box 30 to the conveying portion 40, the crushing portion 50, So that the operation efficiency and the energy efficiency can be enhanced, and the power transmission structure is simple, so that it is easy to manufacture and the operation reliability can be improved.
