Description

Roller type bundling machine

Technical Field

The present invention relates to a roller baler for discharging a roller bale into a field, and more particularly, to a roller baler for discharging a roller bale obliquely rearward when discharging a roller bale.

Background

Generally, a self-propelled roller baler is configured to be provided with: a harvesting part for harvesting corn, rice and the like; a cutting part for cutting the crop harvested from the harvesting part; and a roll forming chamber for forming a cylindrical roll bundle from the chopped crop. After the roll forming chamber forms the roll bundle, a rear chamber of the roll forming chamber is opened, and the roll bundle is placed on a thrower and discharged to a farm field.

However, in such a general roller baler, as shown in fig. 9, since the roller bale 9 is fed out in the direction directly behind the roller baler 1, there is a possibility that the roller bale 9 already placed on a farm land may come into contact when harvesting work or the like is performed in the next adjacent work area.

In order to solve this problem, patent document 1 listed below proposes a roller binding machine in which a roller bundle is fed obliquely rearward in the direction of a work-completed area.

Specifically, as shown in fig. 8, the roller binding machine is provided with left and right guides 10 and 11 fixed to the same height position of the machine body and having different heights at the rear end side, thereby forming an inclined surface in the left-right direction, and the roller bundle 9 is fed obliquely rearward along the inclined surface. With this configuration, since the roller 9 can be paid out to a place distant from the area where the next work is performed, the machine body does not come into contact with the roller 9 in the field.

SUMMERY OF THE UTILITY MODEL

Problem to be solved by utility model

However, the structure shown in fig. 8 has the following problems.

That is, in the configuration shown in fig. 8, since the guides 10 and 11 are fixed by bolts toward the lower rear portion, when the guide moves in a field having irregularities, the rear end portions of the guides 10 and 11 may contact the field. Further, since the guides 10 and 11 are fixed in an inclined state, when the roll bundle 9 is discharged from the roll forming chamber, the roll of the roll bundle 9 generates momentum, the rotation speed of the roll bundle 9 increases, and the crop is scattered from the side surface or the like.

In the configuration of fig. 8, the rear end portion of the guide 11 on the raised side forms an inclined surface in the left-right direction, but in such a configuration, the roller bundle 9 drops from a high position at the rear end portion of the guide 11 when being discharged. Therefore, the roll bundle 9 is deformed or the crop is scattered by the impact caused by the fall.

Therefore, in order to solve the above problem, an object of the present invention is to provide a roll baler capable of carefully releasing a roll bundle obliquely rearward away from the next adjacent work area when the roll bundle is released from a roll forming chamber.

Means for solving the problems

That is, in order to solve the above problem, the present invention provides a roller baler including: a machine body moving in a farm; a roll forming chamber provided in the body, for forming a roll bundle by the chopped crop; and a kicker provided so that the rear portion can be tilted downward from a horizontal state in an initial state, the roller forming chamber being configured to place a roller bundle discharged from the roller forming chamber and roll the roller bundle on a farm field, wherein the roller binding machine is provided with a tilting mechanism for tilting the kicker in a lateral direction by changing a right and left height position of the kicker on a front side when the rear portion is tilted downward from the horizontal state in the initial state.

With this configuration, when the roll bundle is discharged, the discharging speed is reduced by the horizontally-arranged kicker, and then when the roll bundle is rolled, the height of the kicker in the left and right directions is changed by the weight of the roll bundle, and the roll bundle can be discharged obliquely rearward by inclining the kicker in the left and right directions.

In this case, the kicker is provided with a left-side support portion and a right-side support portion on which the left and right portions of the roll bundle are placed, and the tilting mechanism is configured such that the fulcrums for pivoting the left-side support portion or the right-side support portion are provided so as to be offset in the front-rear direction, respectively, and that a plane crossing the left-side support portion and the right-side support portion is brought into a horizontal state in an initial state.

With this configuration, since the pivot points of the rotation of the front sides of the left and right side support portions are offset in the front-rear direction, the left and right height positions of the front sides can be changed when the kicker is tilted, and the roll bundle can be discharged obliquely rearward.

Further, the slinger is configured to be provided with: a left side supporting part and a right side supporting part for loading the left and right parts of the roller bundle; and a shaft that connects the front end portions of the left and right support portions in the left-right direction, and the tilt mechanism includes: left and right pivot points arranged in a staggered manner in the front-rear direction of the machine body; and an arm connecting the pivot and an end of the shaft, wherein in an initial state, the tilt mechanism makes a plane crossing the left and right support sections horizontal, and tilts a rear portion of the kicker downward via the pivot.

With this configuration, since the left-side support portion and the right-side support portion are supported by the shafts, the weight of the roll bundle can be supported by the left-side support portion and the right-side support portion supported by the shafts when the heavy roll bundle is placed.

Further, one of the left and right pivot points is provided at a lower front portion, and the other pivot point is provided at an upper rear portion, and the arm is provided so as to set the shaft to a horizontal state in an initial state.

With this configuration, since the pivot is provided at a position displaced not only in the front-rear direction but also in the vertical direction, the kicker can be largely tilted in the horizontal direction when it is tilted.

Further, a rear connecting portion is provided that connects rear end portions of the left and right support portions in an oblique direction.

With this configuration, the roller bundle can be fed through the rear connecting portion.

Further, the pivot is constituted by a ball joint.

With this configuration, even when the pivot is provided at a position offset in the front-rear direction and in the up-down direction and the pivot is rotated, the left and right support portions coupled to the shaft can be tilted toward the rear lower portion.

Effect of utility model

According to the utility model discloses, when giving out the roller bundle, utilize the throwing ware of horizontality to reduce and give out speed, then when making the roller bundle roll, through the weight of roller bundle, change the height of controlling of the place ahead side of throwing ware and make it incline to left right direction to can make the roller bundle give to oblique rear direction farmland.

Detailed Description

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

The roller baler 1 of the present embodiment is capable of harvesting crops and forming a roller bale 9 while the roller baler is self-propelled in a farm field, and includes a harvesting unit 2, a chopping unit 3, a roller forming chamber 6, a slinger 7, and the like, as shown in fig. 1. The present embodiment will be described in detail below. In the description, the direction in which the roller baler 1 advances is referred to as the front side, the opposite direction is referred to as the "rear side", the left side facing the direction of travel is referred to as the "left side", and the right side is referred to as the "right side".

First, the harvesting unit 2 is provided on the front side of the machine body 1a, and configured to harvest crops by rotating the left and right disk cutters inward with respect to each other, and then to guide the harvested crops between the respective disk cutters.

The cutter 3 can cut the crop harvested in this manner, and can cut the crop introduced in the longitudinal direction by using the fixed knife and the rotary knife. The cut crop is blown up through the chute 4 and discharged to the hopper 5 provided at the upper portion of the machine body 1 a.

The crop discharged into the hopper 5 falls onto a conveyor 61 provided inside the machine body 1a, and is carried into the roll forming chamber 6 from there.

The roller forming chamber 6 forms the cylindrical roller bundle 9 from the crop carried in by the conveyor 61, and rotates the rotating member 62 provided inside in a circumferential manner, thereby rotating the crop to form the roller bundle 9. The roll bundle 9 thus formed can be fed with the web from the web feeding unit 63, wound around the roll bundle 9, and fed.

By opening the rear chamber 64 of the roller forming chamber 6 (the state of fig. 5), the roller bundle 9 wound with the net is paid out toward the rear of the machine body 1 a. When the roll bundle 9 is released, the roll bundle 9 is placed on the kicker 7 held in a horizontal state (upper view in fig. 6), and in this state, the kicker 7 is tilted downward to the rear by the weight of the roll bundle 9 (lower view in fig. 6), and the roll bundle 9 is released into the farm field.

The tilting mechanism 8 of the slinger 7 configured as described above will be described with reference to the schematic diagrams of fig. 2, 3, and 6.

As shown in fig. 2 and 3, the slinger 7 includes: tubular left and

right support portions

71 and 72 that support left and right portions of the roll bundle 9 (omitted from the drawings); a shaft 73 connected to the front ends of the left and

right support portions

71 and 72 in the left-right direction; and a rear coupling portion 74 coupled to the rear end sides of the left and

right support portions

71 and 72 in the lateral direction, and configured to have a substantially U-shape in plan view. As shown in fig. 4 and 5, the front end portions of the left and

right support portions

71 and 72 are initially set at the same height position and the same front-rear position, and as shown in fig. 3, the rear end portion is slightly positioned forward of the rear end side of the right support portion 72, and the rear end portion of the left support portion 71 are coupled in an oblique direction by a rear coupling portion 74.

As shown in fig. 3, the left end of the shaft 73 in the slinger 7 configured as described above is coupled to the left arm 83 so as to curve forward of the machine body 1a from the left pivot 81. On the other hand, the right end of the shaft 73 is coupled to a right pivot point 82 provided at a lower front portion than the left pivot point 81 via a right arm 84. The right arm 84 is provided rearward of the machine body 1a from the right pivot 82, and is folded forward so as to go around the machine body 1a, thereby holding the shaft 73 in a horizontal state.

The kicker 7 is supported by a spring 85 (see fig. 2 and 3) in an initial state so that a plane extending across the left and

right support portions

71 and 72 becomes a horizontal plane, and thus when the roll bundle 9 is released from the roll forming chamber 6, the roll bundle 9 is temporarily received by the plane, and the release speed is reduced.

In the case where the thrower 7 is provided in this manner, if the thrower 7 is provided at a high position close to the discharge portion of the roller forming chamber 6, the impact due to the step can be reduced when the roll bundle 9 is discharged, but if the thrower 7 is provided at the upper side in this manner, the impact interferes with the rear chamber 64. Therefore, as shown in fig. 4, in a state where the rear chamber 64 is closed, the left and right pivot points 81 and 82 of the slinger 7 are lowered to lower the entire slinger 7, and as shown in fig. 5, the rear chamber 64 is opened to raise the left and right pivot points 81 and 82 by the same distance. When the kicker 7 is raised and lowered in this manner, first, a long hole 65 extending in the vertical direction is formed on the side of the machine body 1a, and the left-side pivot point 81 and the right-side pivot point 82 are attached to the long hole 65. Then, the right arm 83 connected to the left and right pivot points 81 and 82 and the upper side portion of the rear chamber 64 are connected by a rod 66 or the like, and the rear chamber 64 is opened, so that the entire slinger 7 is raised.

Next, an operation when the roll bundle 9 is discharged from the roll forming chamber 6 using the thrower 7 configured as described above will be described with reference to a schematic diagram of fig. 6 and the like.

When the roll bundle 9 is discharged from the roll forming chamber 6, the rear chamber 64 is opened. Then, as the rod 66 is pulled upward along with the opening, the left and

right support portions

71 and 72 of the slinger 7 are lifted up along the long hole 65.

The roll bundle 9 is then paid out onto the kicker 7 by fully opening the rear chamber 64. At this time, the plane crossing the left and

right support portions

71 and 72 of the slinger 7 becomes horizontal, and the roll bundle is temporarily received on the horizontal plane to reduce the discharge speed.

When the roll bundle 9 is placed on the kicker 7 in this manner, the kicker 7 gradually tilts to the lower rear portion against the force of the spring 85.

At this time, as shown in the lower drawing of fig. 6, the left side support portion 71 of the slinger 7 is inclined about the left side pivot point 81, while the right side support portion 72 is inclined about the right side pivot point 82. Thus, the left side support portion 71 is higher than the right side support portion 72 at the same position, and an inclined surface can be formed in the left-right direction. Here, since the right pivot support 82 is provided at the lower front portion and the left pivot support 81 is provided at the upper rear portion, the kicker 7 is pivoted obliquely rearward about a straight line connecting the respective pivots as a pivot shaft, and a plane extending across the left support portion 71 and the right support portion 72 can be further tilted. This makes it possible to further increase the angle of inclination in the left-right direction and to feed the roller bundle 9 obliquely to the right and rearward.

When the roller bundle 9 is paid out in this way, the roller bundle 9 is rolled in a state where the roller bundle 9 is also placed on the rear connecting portion 74 provided on the rear end side of the left and right supporting

portions

71 and 72.

Then, as in the roller baler 1 shown on the lower side of fig. 9, the roller bundle 9 thus fed along the inclined surface is fed obliquely rearward to the already-worked region, and the kicker 7 is returned to the horizontal state of the initial state by the force of the spring 85.

< second embodiment >

In the above embodiment, the kickers 7 having a substantially U-shape are provided, and the left and right pivot points are provided so as to be offset in the front-rear direction and the up-down direction, but the roll bundle may be fed obliquely rearward as shown in fig. 7.

In fig. 7 of the second embodiment, the right support portion 72 is rotatably supported on a right pivot point 82 provided on the front side of the machine body 1a, and the left support portion 71 is rotatably provided on a left pivot point 81, the left pivot point 81 being provided at the same height position as the right pivot point 82 and at the same height position as the rear side of the machine body 1 a. The right and left

support portions

72, 71 are independently tilted, and are initially kept horizontal by the force of the spring 85.

In such a situation, when the roll bundle 9 is discharged from the roll forming chamber 6, the roll bundle 9 is placed on the slinger 7 in a horizontal state as in the first embodiment, and therefore the discharge speed is temporarily lowered.

Then, after the roll bundle 9 is placed on the slinger 7, the left and

right support portions

71 and 72 are tilted by the self weight of the roll bundle 9.

At this time, since the right pivot 82 of the right support portion 72 is provided on the front side, the right support portion 72 is lower than the left support portion 71 as shown in the lower drawing of fig. 7 when the slinger 7 tilts. Accordingly, the inclined surface can be formed in the left-right direction by the difference in the left-right height, and the roller bundle 9 can be fed obliquely rearward as in the roller binding machine 1 shown in the lower side of fig. 9.

As described above, according to the above embodiment, the roller-type baler 1 includes the machine body 1a, the roller-forming chamber 6, and the thrower 7, the machine body 1a moves in a farm field, the roller-forming chamber 6 is provided in the machine body 1a, the chopped crop-forming roller bundle 9 is formed, the thrower 7 is provided to be tiltable toward the lower rear side from the horizontal state in the initial state, the roller bundle 9 discharged from the roller-forming chamber 6 is placed and rolled on the farm field, the roller-type baler 1 is provided with the tilting mechanism 8, and when the thrower 7 is tilted rearward and downward from the horizontal state in the initial state, the tilting mechanism 8 changes the left and right height positions on the front side of the thrower 7 and tilts the thrower 7 in the lateral direction, so that the discharge speed of the roller bundle 9 is reduced by the thrower 7 in the horizontal state, and then when the roller bundle 9 is rolled, the weight placed on the thrower 7 is tilted so that the left and right heights on the front side of the thrower 7 are different, and the thrower 9 can be tilted toward the rear side of the roller bundle 9.

The present invention is not limited to the above embodiments, and can be implemented in various ways.

For example, in the above embodiment, the crop is harvested by using a pair of circular cutters as the harvesting unit 2, and the harvested crop is blown up by the chute 4 and collected by the hopper 5, but the crop may be harvested by using another type of harvesting unit 2. In the above embodiment, the structure in which the crop is harvested by the harvesting unit 2 is used, but the present invention may be applied to the roller baler 1 that picks up the crop that has been cut and placed on the farm field to form the roller bale 9.

In the above embodiment, the tubular left and

right support portions

71 and 72 are provided as the kicker 7, but the kicker 7 may be formed of a plate-like plate, and the front height position may be changed by shifting the positions of the left and right pivot points 81 and 82 of the left and right shafts 73 provided on the front end side of the plate back and forth.

In the above embodiment, the kicker 7 is raised and lowered in accordance with the opening and closing of the rear chamber 64, but the height position may be fixed without raising and lowering the kicker 7.
