To achieve the purpose, the combine is equipped with a rotating reel located at the top of the bucket of the cutting device; a fixating bracket fixated on a horizontal bar of the reel; and the tine, detachably mounted on the fixating bracket, for pressing the crops into the cutting device and introducing crops located in front of the cutting device by the rotation of the reel.

Description

The reel of the combine {Reel of Combine}

The present invention relates to a combine reel for introducing a crop (hereinafter referred to as a " garment crop ") fallen by rain or wind into a reel preliminary part, And can be harvested by inflow, and is constructed so as to prevent breakage of the others due to uneven ground.

The combine is a device used to cut rice, barley, wheat, soybean, and other grains while traveling on the rice field, to thresh, and to sort and select.

The combine consists of a running section, a preliminary section, a feed section for transferring the cut crop to the threshing section, a threshing / sorting section for threshing and sorting the grain, a grain processing section for transferring the grain to the tank or the turret, and a rice straw processing section.

On the other hand, in the case of grains having a high stem, grains flow smoothly into the cutting section due to cutting of the stem while the combine proceeds, but it is difficult to introduce the crops into the cutting section as a normal cutting operation .

Thus, a reel is mounted on the preloading section, and the reel rotates at the top of the preloading section to allow the cropping crop to flow into the cutting section.

The reels are shaped like a spindle and others are fixed to the horizontal bar by welding or the like. Therefore, when the reel is rotated, the overgrown crop is caught by the other person and flows into the cutting part which is the direction of rotation of the reel. In this state, the cutting edge of the preliminary cutting part cuts the stem of the overgrown crop.

However, because the ground is not flat because the agricultural land is formed with a ladder, the problem of colliding with the ground occurs when the reel rotates.

In the conventional reel, since the tines are fixed to the horizontal bar, when any one of a plurality of tines fixed to the horizontal bar is broken, the entire horizontal bar must be replaced, resulting in cost and time loss.

The conventional tines are fixed to the horizontal bar of the reel, and during the process of pushing the overgrown crop into the preliminary part, the conventional tandem of a small elastic material moves over the overgrown crop rather than rubbing the overgrown crop The crop will no longer be pushed to the inside of the sample by moving away from the other person.

1, a preload portion 20 is located in front of the combine 10 and the grain cut at the preload portion 20 is fed to a feed portion 30 connected to the bucket 21 of the preload portion 20, To the threshing section (40).

A reel 100 is installed on the bucket 21 of the preloading unit 20 to allow the grains to flow into the preloading unit 20. The reels 100 are arranged such that each end of the five horizontal bars 105 And is fixed to a reel frame 101 formed by a five-angle radiation structure. The reel frame 101 is rotatably mounted on the arm 103 and is rotated by the power for rotating the reel frame 101. The direction of rotation of the reel 100 at this time is the direction of rotation of the reel 100, In the direction in which it can be pulled into the preload part (20).

A tine 120 having the same function as a rake for introducing the coated grains into the pre-installation portion 20 is mounted vertically in the longitudinal direction of each horizontal bar 105 on the horizontal bar 105 of the reel 100 having the above-

The connection structure of the tines 120 and the fixing bracket 110 fixed to the horizontal bar 105 will be described in detail below.

As shown in FIGS. 2 to 4, a plurality of fixing brackets 110 are fixed to the horizontal bar 105 of the reel 100 with a gap therebetween.

The fixing bracket 110 is provided with an insertion hole 111 into which the bending end of the tang 120 is inserted and a bolt 115 fastened to press the tangs 120 seated on the fixing bracket 110 A boss 113 is formed.

The boss 113 has a height equal to or lower than the diameter of the tines 120 and is tap-formed such that the bolt 115 is fastened to the inside of the boss 113. 2, two tines 120 may be mounted on the fixing bracket 110, but one or more tines may be mounted.

The washer 114 and the bolt 115 are sequentially tightened after the tines 120 are seated on the boss 113. If the height of the boss 113 is higher than the height of the tines 120, The boss 113 and the tines 120 can not be pressed at the same time so that the tines 120 are not firmly fixed to the fixing bracket 110 so that the diameter of the tines 120 and the height of the bosses 113 are made equal It is preferable to make the height of the boss 113 lower than the diameter of the tines 120. [

If the height of the boss 113 is larger than the diameter of the tines 120 and the tines 120 can not be properly fixed to the fixing bracket 110, the tines 120 may protrude from the fixing bracket 110 during operation The components such as the washer 114 and the bolt 115 may be damaged due to the movement of the tines 120.

The insertion hole 111 of the fixing bracket 110 is formed such that the length from the portion where the tines 120 contact the boss 113 to the bending end of the tines 120 when the tines 120 are machined, Is formed as a long hole in order to compensate for the presence.

On the other hand, the tangs 120 of spring steel are mounted on the fixing bracket 110.

5, the tines 120 are formed by bending and bending a spring steel wire, and the shape and function of each part along the length direction from the rear end to the tip end of the tines 120 will be described below .

The tines 120 include an insertion portion 121 having a rear end bent downward to be inserted into the insertion hole 111 of the fixing bracket 110 and a U- An elastic reinforcing part 125 which is bent in a circular shape in front of the mounting part 123 so as to increase the elasticity and a front end part bent downward at the elastic reinforcing part 125, And a rake portion 127 which is drawn into the pre-loading portion 20 for drawing.

When the insertion portion 121 is inserted into the insertion hole 111 of the fixing bracket 110, the fixing bracket 110 (not shown) is inserted into the mounting portion 123 when the insertion portion 121 is inserted into the insertion hole 111 of the fixing bracket 110, And the mounting portion 123 and the elastic reinforcing portion 125 are located on the plane of the fixing bracket 110. [ Therefore, the rake portion 127 bent downward is positioned to extend forwardly downward of the fixing bracket 110.

When the fixing bracket 110 is fixed to the horizontal bar 105, the inclination angle of the fixing bracket 110 is set such that the tip of the tine 120, that is, the rake portion 127 is located at the lowest position It is preferable that the fixing bracket 110 is fixed to the horizontal bar 105 at an inclination of about 45 degrees.

The insertion portion 121 of the tine 120 is inserted into the insertion hole 111 of the fixing bracket 110 and the boss 113 is inserted into the insertion hole 111 of the fixing bracket 110. [ And the mounting position is set so as to be located inside the mounting portion 123. When the washer 114 and the bolt 115 are fastened to the boss 113, the mounting portion 123 and the elastic reinforcing portion 125 are positioned on the plane of the fixing bracket 110, The head 115H presses the washer 114 and fixes the tines 120 while the washer 114 presses the upper surface of the mounting portion 123 of the boss 113 and the tines 120. [

When the reel 100 rotates and the rake portion 127 of the tine 120 draws the overgrown crop into the inside of the preload portion 20, the force applied in the left and right directions of the tine 120 is transmitted to the insertion hole 111 and the mounting portion 123 that surrounds the boss 113. The insertion portion 121 is inserted into the insertion portion 121 of the insertion portion 121 and the insertion portion 123 of the insertion portion 121 of the insertion portion 123 of the insertion portion 121, That is, the force applied in the left and right directions is lost in the insertion portion 121 and the mounting portion 123, thereby blocking the tines 120 from flowing in the left and right directions.

The rake portion 127 is elastically deformed upward by the force applied to the rake portion 127 that draws the overturned grains. The rake portion 127 is further deformed upward by the elastic reinforcement portion 125 The elastic force generated in the rake portion 127 becomes greater than the force applied to the rake portion 127. As a result, the rake portion 127 is restored to its original position, ).

If some of the tines 120 mounted on the reel 100 are broken or plastically deformed and thus do not have the original shape, the operator unfastens the bolt 115 and fixes the tines 120 to the fixing bracket 110 and then replaced with a new one as described above.

In the above-described combine, in the above-described example, the fixing bracket 110 is mounted on the entire length of the horizontal bar 105 of the reel 100, and the tines 120 are mounted on the respective fixing brackets 110 The fixing bracket 110 and the tines 120 may be mounted on both ends of the horizontal bar 105 as occasion demands.

This is because the tines or both ends of the cropland, that is, the tines located at the opposite ends of the horizontal bar 105 are subjected to a greater resistance than the tines located inside the length of the horizontal bar 105, to be.

One tine 120 is attached to the fixing bracket 110 fixed to both ends of one horizontal bar 105 and two tines 120 are fixed to the fixing bracket 110 fixed to both ends of another adjacent horizontal bar 105. [ (120) may be mounted. That is, in the case of the reel 100 having five horizontal bars 105 as shown in FIG. 2, two tines 120 are provided on the fixing bracket 110 fixed to both ends of the three horizontal bars 105 And one tine 120 is mounted on the fixing bracket 110 fixed to both ends of the remaining two horizontal bars 105. These horizontal bars 105 are arranged along the periphery of the reel frame 101 And have patterns arranged alternately.

On the other hand, the above-described reel 100 has a pentagonal structure in which five horizontal bars 105 are mounted, but a reel 100 having a hexagonal structure as shown in FIG. 6 can be constructed.

In this case, two tines 120 are mounted on the fixing bracket 110 fixed to both ends of the three horizontal bars 105, and a fixing bracket 110 fixed to both ends of the remaining three horizontal bars 105 Are mounted, and these horizontal bars (105) constitute the reel (100) in a mutually alternating pattern.

By configuring the reel 100 in such a pattern that one tine 120 is mounted on both ends of the horizontal bar 105 and two tines 120 are mounted on both ends of the adjacent horizontal bar 105, One or two tines mounted on both ends of the horizontal bar 105 alternately move the overgrown crop to the inside of the preload so that the efficiency of pushing the overgrown crop into the preload can be further increased .

That is, in the reel structure of the existing combine, the object and effect of the present invention can be obtained even when the fixing bracket and the tine of the present invention are mounted only at both ends of the horizontal bar.
