Description

[Technical Field]

[0001] The present invention relates to a roll baler that discharges roll bales into a field, and more particularly to a roll baler that discharges the roll bale obliquely backward when discharging the roll bale. [Background technology]

[0002] Generally, a self-propelled roll baler is comprised of a reaping section that harvests corn, rice, etc., a shredding section that shreds the crop harvested by the reaping section, and a roll forming chamber that forms cylindrical roll bales from the shredded crops. After the roll bale is formed in the roll forming chamber, the rear chamber of the roll forming chamber is opened and the roll bale is placed on a kicker and released into the field.

[0003] However, with such a typical roll baler, as shown in Figure 9, the roll bale 9 is released directly behind the roll baler 1, so when harvesting work is performed in the next adjacent work area, there is a possibility that the roll bale 9 will come into contact with a roll bale 9 that has already been left in the field.

[0004] To solve this problem, Patent Document 1 below proposes a round baler that discharges round bales diagonally backward, in the direction of the area where work has already been done.

[0005] Specifically, as shown in Figure 8, this round baler is equipped with left and right guides 10, 11 that are fixed at the same height on the machine body but have different heights at their rear ends, forming a slope that slopes left and right, and the roll bale 9 is discharged diagonally backward along this slope. With this configuration, the roll bale 9 can be discharged to a location away from the next work area, so the machine body will not come into contact with the roll bale 9 in the field.

[0006] [Patent Document 1] Japanese Utility Model Application Publication No. 63-145439 Summary of the Invention [Problem to be solved by the invention]

[0007] However, the structure shown in FIG. 8 causes the following problems.

[0008] 8, because the guide tools 10, 11 are fixed with bolts facing downward toward the rear, there is a possibility that the rear ends of the guide tools 10, 11 may come into contact with the field when traveling over uneven terrain. Also, because the guide tools 10, 11 are fixed in an inclined position, the roll of the roll bale 9 gains momentum when it is released from the roll forming chamber, increasing the rotation speed of the roll bale 9 and causing crops to spill over the sides, etc.

[0009] In addition, in the structure shown in Figure 8, the rear end of one of the guide tools 11 is elevated to form a lateral slope, but with this configuration, when the roll bale 9 is released, it falls from the high rear end of the guide tool 11. As a result, the impact of the fall can cause deformation of the roll bale 9 or cause the crops to spill out.

[0010] Therefore, in order to solve the above problem, the present invention aims to provide a roll baler that can carefully release a roll bale from the roll forming chamber diagonally backward, away from the next adjacent work area. [Means for solving the problem]

[0011] In other words, in order to solve the above-mentioned problems, the present invention provides a roll baler comprising a body that travels through a field, a roll forming chamber that is attached to the body and forms roll bales from chopped crops, and a kicker that is adapted to tilt the rear portion downward from its initial horizontal state and that loads the roll bale released from the roll forming chamber and rolls it into the field, and which is provided with a tilting mechanism that changes the height positions of the left and right sides of the front side of the kicker so that it tilts sideways when the rear portion of the kicker is tilted downward from its initial horizontal state.

[0012] With this configuration, when releasing a roll bale, the release speed is reduced by using a horizontal kicker, and then when rolling the roll bale, the height of the left and right sides of the front side of the kicker is changed depending on the weight of the roll bale, causing it to tilt left and right, allowing the roll bale to be released diagonally backward.

[0013] In addition, in such an invention, the kicker is configured to include a left support section and a right support section on which the left and right portions of the roll bale are placed, and the tilting mechanism is configured so that the fulcrum around which the left support section or the right support section rotates is shifted in the front-to-rear direction, and so that in the initial state, the plane spanning the left support section and the right support section is horizontal.

[0014] With this configuration, the pivot points on the front sides of the left and right support parts are offset in the front-to-rear direction, so when tilting the kicker, the height positions on the left and right sides of the front side can be kicked, and the roll bale can be released diagonally rearward.

[0015] Furthermore, the kicker is configured with a left support section and a right support section on which the left and right portions of the roll bale are placed, and a shaft connecting the front ends of the left and right support sections in the left-right direction, and the tilting mechanism is configured with a pivot point offset in the fore-and-aft direction of the machine body, and an arm connecting the pivot point to the end of the shaft, so that in the initial state the plane spanning the left and right support sections is horizontal, and the rear of the kicker is tilted downward via the pivot point.

[0016] With this configuration, the left and right support parts are supported by the shaft, so when a heavy roll bale is placed on it, the left and right support parts supported by the shaft can support the weight of the roll bale.

[0017] Furthermore, one of the left and right rotation fulcrums is provided at the front lower part and the other is provided at the rear upper part, and the arm is set so that the shaft is in a horizontal position in the initial state.

[0018] With this configuration, the pivot points are positioned not only forward and backward but also up and down, so that when tilting the kicker, it can be tilted greatly in the left and right directions.

[0019] In addition, a rear connecting portion is provided that connects the rear end portions of the left support portion and the right support portion in an oblique direction.

[0020] With this configuration, it becomes possible to discharge the round bale through the top of the rear connecting portion.

[0021] The pivot point is formed of a ball joint.

[0022] With this configuration, even if the pivot point is set at a position shifted forward, backward, up or down, the left support part and the right support part connected to the shaft can be tilted toward the rear and lower part. [Effects of the Invention]

[0023] According to the present invention, when a roll bale is released, the release speed is reduced by using a horizontal kicker, and then when the roll bale is rolled, the height of the left and right sides of the front side of the kicker is changed depending on the weight of the roll bale, causing it to tilt left and right, so that the roll bale can be released diagonally backward into the field.

[0025] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0026] The roll baler 1 in this embodiment is capable of performing operations from harvesting crops to forming roll bales 9 while self-propelled in a field, and as shown in Figure 1, is configured to have a harvesting section 2, a shredding section 3, a roll forming chamber 6, a kicker 7, etc. This embodiment will be described in detail below. In the description, the direction in which the roll baler 1 moves forward will be referred to as the forward side, the opposite direction will be referred to as the "rear", the left side of the direction of travel will be referred to as the "left side", and the right side will be referred to as the "right side".

[0027] First, the reaping unit 2 is provided on the front side of the machine body 1a, and is configured so that the left and right disc cutters are rotated inwardly to cut the crops, and then the cut crops can be collected between the respective disc cutters.

[0028] The shredding unit 3 is designed to shred the harvested crops using fixed and rotary blades, and the shredded crops are blown up through the chute 4 and released into a hopper 5 located at the top of the machine body 1a.

[0029] The crops released into this hopper 5 fall onto a conveyor 61 provided inside the machine body 1 a, and are then carried from there into the roll forming chamber 6 .

[0030] The roll forming chamber 6 forms cylindrical roll bales 9 from crops brought in by a conveyor 61, and rotates a rotating member 62 provided inside in a circular motion, causing the crops to rotate on their own axis and form the roll bale 9. A net is fed from a net feeding section 63 onto the roll bale 9 formed in this way, and the net can be wrapped around the roll bale 9 before being released.

[0031] The roll bale 9 with the net wrapped around it in this way is released towards the rear of the machine body 1a by opening the rear chamber 64 of the roll forming chamber 6 (as shown in Figure 5). When releasing the roll bale 9, the roll bale 9 is placed on the kicker 7, which is held horizontally (as shown in the upper diagram of Figure 6), and in this state the weight of the roll bale 9 causes the kicker 7 to tilt downward and towards the rear (as shown in the lower diagram of Figure 6), releasing the roll bale 9 into the field.

[0032] The tilting mechanism 8 of the kicker 7 configured in this manner will be described with reference to the principle diagrams of FIGS. 2, 3 and 6. FIG.

[0033] 2 and 3, the kicker 7 is configured to have a generally U-shape in plan view, and includes a pipe-shaped left support section 71 and a pipe-shaped right support section 72 that support the left and right sides of a roll bale 9 (not shown), a shaft 73 that connects the front ends of the left support section 71 and the right support section 72 in the left-right direction, and a rear connector 74 that connects the rear ends of the left support section 71 and the right support section 72 in the left-right direction. As shown in FIGS. 4 and 5, the front ends of the left support section 71 and the right support section 72 are initially positioned at the same height and in the same front-to-rear position, and as shown in FIG. 3, the rear end of the right support section 72 is positioned slightly forward, and its rear end is connected obliquely to the rear end of the left support section 71 by the rear connector 74.

[0034] In the kicker 7 configured in this manner, the left end of the shaft 73 is connected to a left arm 83 so as to bend from a left rotation fulcrum 81 toward the front of the machine body 1a, as shown in Figure 3. On the other hand, the right end of the shaft 73 is connected via a right arm 84 to a right rotation fulcrum 82 provided below and forward of the left rotation fulcrum 81. This right arm 84 is provided from the right rotation fulcrum 82 toward the rear of the machine body 1a and is bent back toward the front, bypassing the machine body 1a, so that the shaft 73 can be kept horizontal.

[0035] In its initial state, the kicker 7 is supported by a spring 85 (see Figures 2 and 3) so that the plane spanning the left support section 71 and the right support section 72 is horizontal. As a result, when the roll bale 9 is released from the roll forming chamber 6, the roll bale 9 is temporarily received on this plane, thereby reducing the release speed.

[0036] When providing the kicker 7 in this manner, if the kicker 7 is provided at a high position near the discharge portion of the roll forming chamber 6, the impact caused by the step when the roll bale 9 is discharged can be reduced. However, if the kicker 7 is provided at a high position like this, it will interfere with the rear chamber 64. Therefore, as shown in FIG. 4, with the rear chamber 64 closed, the left and right pivot points 81 and 82 of the kicker 7 are lowered to lower the kicker 7 as a whole, and then, 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. To raise and lower the kicker 7 in this manner, first, elongated holes 65 are formed in the vertical direction on the sides of the machine body 1a, and the left and right pivot points 81 and 82 are attached to the elongated holes 65. The right arm 83 connected to the left pivot point 81 and the right pivot point 82 is connected to the upper part of the side of the rear chamber 64 by a rod 66 or the like, and by opening the rear chamber 64, the kicker 7 is raised as a whole.

[0037] Next, the operation of releasing the roll bale 9 from the roll forming chamber 6 using the kicker 7 configured as above will be described with reference to the principle diagram of FIG.

[0038] When the roll bale 9 is released from the roll forming chamber 6, the rear chamber 64 is opened. As the rear chamber 64 opens, the rod 66 attached to the side of the rear chamber 64 is pulled upward, causing the left support part 71 and the right support part 72 of the kicker 7 to rise along the elongated hole 65.

[0039] Then, by fully opening the rear chamber 64, the round bale 9 is released onto the kicker 7. At this time, the plane spanning the left support part 71 and the right support part 72 of the kicker 7 is horizontal, and the roll bale is once received on this horizontal plane, reducing the release speed.

[0040] When the round bale 9 is placed on the kicker 7 in this manner, the kicker 7 gradually tilts downward and rearward against the force of the spring 85.

[0041] At this time, as shown in the lower diagram of Figure 6, the left support part 71 of the kicker 7 tilts around the left pivot fulcrum 81, while the right support part 72 tilts around the right pivot fulcrum 82. As a result, the left support part 71 is higher than the right support part 72 at the same position, and an inclined plane can be formed in the left-right direction as well. In addition, because the right pivot fulcrum 82 is located at the lower front and the left pivot fulcrum 81 is located at the upper rear, the kicker 7 rotates diagonally backward around the tilted line connecting the respective pivots as a rotation axis, and the plane spanning the left support part 71 and the right support part 72 can be tilted more greatly. This increases the tilt angle in the left-right direction, allowing the roll bale 9 to be released diagonally backward to the right.

[0042] When the roll bale 9 is released in this manner, the roll bale 9 also rolls while resting on the rear connecting portion 74 provided at the rear end of the left support portion 71 and the right support portion 72.

[0043] The roll bale 9 thus released along the inclined surface is then released diagonally backward, to an area where work has already been completed, as in the roll baler 1 shown at the bottom of Figure 9, and the kicker 7 is returned to its initial horizontal state by the force of the spring 85.

[0044] <Second embodiment>

[0045] In the above embodiment, a roughly U-shaped kicker 7 is provided, and the left and right rotation fulcrums are offset from one another in the front-to-back and up-to-down directions. However, as shown in Figure 7, it is also possible to release the roll bale diagonally backward.

[0046] 7 showing the second embodiment, the right support part 72 is rotatably supported on a right rotation fulcrum 82 provided on the front side of the machine body 1a, and the left support part 71 is rotatably provided on a left rotation fulcrum 81 provided on the rear side of the machine body 1a at the same height as the right rotation fulcrum 82. The right support part 72 and the left support part 71 are each designed to tilt independently, and are kept in a horizontal state in the initial state by the force of a spring 85.

[0047] Under these circumstances, when the roll bale 9 is released from the roll forming chamber 6, the roll bale 9 is placed on the horizontal kicker 7, as in the first embodiment, and the release speed is temporarily reduced there.

[0048] After the roll bale 9 is placed on the kicker 7, the left support part 71 and the right support part 72 are tilted by the roll bale 9's own weight.

[0049] At this time, because the right-side rotation fulcrum 82 of the right-side support part 72 is located on the forward side, when the kicker 7 tilts, the right-side support part 72 becomes lower than the left-side support part 71, as shown in the lower diagram of Figure 7. As a result, the difference in height between the left and right sides makes it possible to form an inclined surface in the left-right direction, and it becomes possible to release the roll bale 9 diagonally backward, as in the roll baler 1 shown in the lower part of Figure 9.

[0050] According to the above embodiment, the roll baler 1 comprises a body 1a that travels through the field, a roll forming chamber 6 that is attached to the body 1a and that forms roll bales 9 from chopped crops, and a kicker 7 that is tiltable from its initial horizontal state toward the rear and downwards, and that loads the roll bale 9 released from the roll forming chamber 6 and rolls it into the field.When the kicker 7 is tilted rearward and downwards from its initial horizontal state, a tilting mechanism 8 is provided that changes the height positions of the front left and right sides of the kicker 7, thereby tilting it laterally as well.This reduces the release speed of the roll bale 9 when the kicker 7 is in the horizontal position, and then, when the roll bale 9 is rolled, the kicker 7 is tilted so that the front left and right sides are at different heights depending on the weight of the roll bale when it is placed on the kicker 7, allowing the roll bale 9 to be released diagonally rearward.

[0051] The present invention is not limited to the above-described embodiment, but can be implemented in various forms.

[0052] For example, in the above embodiment, a pair of disc cutters is used as the reaping unit 2 to harvest crops, which are then blown up by the chute 4 and collected in the hopper 5, but other types of reaping units 2 may be used to harvest crops. Also, while the above embodiment uses a structure in which crops are harvested by the reaping unit 2, this may also be applied to a roll baler 1 that picks up crops that have already been shredded and left in the field and forms them into roll bales 9.

[0053] Furthermore, in the above embodiment, the kicker 7 is provided with a pipe-shaped left support portion 71 and a right support portion 72, but the kicker 7 may be formed from a plate, and the positions of the left and right pivot points 81 and 82 of the left-right shaft 73 provided on the front end side of the plate may be shifted forward or backward to change the height position on the front side.

[0054] Furthermore, 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 kicker 7 may be fixed at a fixed height without being raised and lowered. [Explanation of symbols]
