BACKGROUND OF THE INVENTION
The present invention relates to a roll bale having a configuration in which when a roll bale in which a strip of pasture is formed into a cylindrical shape is released by a roll baler, the roll bale is inverted by 90 ° and left in a standing posture in which a circular plane portion is in contact with a field scene It relates to a discharge device.
[0002]
[Prior art]
A roll baler is a pasture harvester that picks up the grass that has been dried and dried in the field and forms it into a belt, and then forms the roll bale by binding the outer periphery of the belt with a string. It is. The roll bale formed in a cylindrical shape with this roll baler is released as it is from the machine body to the field, and is left as it is until collected later.
[0003]
As a conventional roll veil discharging apparatus, one shown in FIGS. 18 and 19 is known. In this discharge device, a trailer 52 is connected to the rear side of the body frame 51 of the roll baler 50, and is rotated to the side of the floor of the trailer 52 by a hydraulic cylinder 53 around one end in the width direction. In this configuration, a moving frame 54 is provided. The cylindrical roll bale R formed by the roll baler 50 rolls from the rear end portion thereof and is discharged onto the trailer 52 and collides with a stopper bar 55 provided at the rear end portion of the trailer 52 to stop. Thereafter, the rotation frame 54 is rotated laterally by the hydraulic cylinder 53, so that the roll veil R placed on the rotation frame 54 with the central axis substantially parallel to the field scene is circular. It is inverted 90 ° to the side of the trailer 52 so that the flat surface is in contact with the farm scene.
[0004]
Since the above-described discharging device is configured to pull the trailer 52 behind the roll baler 50, the total length becomes long, making it difficult to perform the original grass harvesting work by the roll baler, and also releasing the roll bale R by hydraulic pressure. Since the posture is controlled, the structure is complicated and expensive. Even though the cost is high, the roll bale R discharged from the roll baler 50 toward the trailer 52 may be shifted to the left and right, and may not be discharged onto the trailer 52 in a correct posture. Further, even if the roll bale R is released to the trailer 52 in a correct posture, the rotation frame 54 is rotated and the roll bale R is reversed by 90 ° to the side, and the roll bale R exceeds 90 ° due to inertial force. In some cases, the circumferential surface of the roll bale R comes into contact with the field, and the circular flat portion of the roll bale R cannot stand in a stable posture standing in contact with the field scene. In addition, even if the circular flat portion of the roll bale R is allowed to stand in a normal posture in contact with the field scene, this standing position is a position that is largely away from the side of the main body of the roll baler 50. It becomes an obstacle to the next roll bale work.
[0005]
[Problems to be solved by the invention]
According to the present invention, a discharge device having a simple configuration that does not have a power drive unit is integrated into a roll baler so that the roll bale is inverted by 90 ° almost immediately after the roll baler only by the energy of the roll bale when discharged from the roll baler. The challenge is to make it possible to release in a standing position.
[0006]
[Means for Solving the Problems]
In order to solve this problem, the present invention provides a kick bale in which a kicker that tilts backward in conjunction with opening and closing of the rear case is provided at the rear part of the fuselage frame, and a belt-like pasture is formed in a cylindrical shape by a roll baler. A roll bale discharge device for releasing the roll bale by turning it 90 degrees so that the circular flat surface is in contact with a field scene when rolling up and discharging, and rolls on the kicker One end portion in the width direction of the fuselage frame , which is greatly biased to one side from the center portion in the direction of the central axis of the roll bale that is being released, and further to the rear than the rear end portion of the kicker with inverted poles are disposed in a portion located, anti-tip arm at the end opposite to the side where the inversion pole are arranged in the width direction of the body frame is extended to the body rearwardly That provided is characterized on its configuration.
[0007]
The roll bale released from the roll baler and rolling on the kicker stops its rolling motion when one end in the central axial direction collides with the reverse pole, and the roll bale immediately after the collision Only one end in the axial direction receives a reaction force locally from the reversing pole. On the other hand, the other end portion of the roll bale in the central axis direction at the time of the collision is located on the side of the kicker, and there is nothing in the field immediately below it. For this reason, one end portion of the roll bale in the central axis direction is pushed forward by the reaction force, and the other end portion is further moved rearward, so that the roll bale is arranged in the central axis direction with the inverted pole as a fulcrum. It is inverted so that the circular flat part at the other end of the earth contacts the field scene. The roll bale during the reversing motion may try to reverse more than 90 ° due to its inertial force. In this case, the roll bale in the reversing motion is slightly reversed (returned) in the reverse direction by colliding with the fall prevention arm disposed on the side thereof, and the circular flat portion is lowered. It is left standing in the field with the standing posture.
[0008]
In this way, when the roll bale released from the roll baler is reversed over 90 °, the roll bale during the reverse motion collides with the fall prevention arm to prevent the fall. Of course, in the case of a farm field, the roll veil can be stably inverted and placed in an inclined farm field. In this case, the fall prevention arm is divided into two along the longitudinal direction, and the part arranged on the rear end side is crossed in an obtuse angle with the part arranged on the front end side and rotated inward. If it is configured to be able to rotate only outward from the return position against the urging force to be increased, the impact of the impact force of the roll bale during the reversing motion is increased beyond 90 °, and the lateral direction of the roll bale In addition to the above-mentioned fall, there is a unique advantage that it is possible to prevent a fall toward the rear side.
[0009]
Further, since the position of the roll bale with respect to the roll baler is immediately after the roll baler that is in operation, the roll bale that is left in the standing posture does not become an obstacle to the next roll bale operation. Furthermore, by providing a non-slip projection on the kicker to prevent the roll bale from moving laterally during rolling, the roll bale discharge orientation along the width direction (left and right) of the roll baler is stabilized and reversed. If the pole is provided with a non-slip projection so as to prevent the roll veil during reversal from slipping in the direction of the central axis, the reversal movement of the roll bale is reliably performed.
[0010]

The bent portion 15a is connected to the straight portion 15b of the latter half, and the fall prevention frame 17 is fixed vertically below the straight portion 15b. Further, as shown in FIGS. 7 to 10, a fan-shaped swivel plate 18 is horizontally fixed to the base end portion of the first fall prevention arm 15 to constitute one side portion of the body frame 4. The first support plate 19 is fixed horizontally at the rear end portion of the vertical rod 4b and on the outer portion thereof, and the second support plate 21 is fixed in the same manner directly below the first support plate 19. Has been. The swivel plate 18 is placed on the upper surface of the first support plate 19, and a swivel shaft 22 provided integrally with the swivel plate 18 is supported by the first and second support plates 19 and 21. The swivel plate 18 is provided with a pair of engagement holes 23 a and 23 b on the same circumference around the swivel axis 22, and the engagement pin of the engagement tool 24 mounted on the lower surface of the first support plate 19. 24a and one of the pair of engagement holes 23a and 23b are detachably engaged, so that the first fall prevention arm 15 is in a use state or a retracted (folded) state. . An engagement release lever 24c is provided immediately below the main body 24b of the engagement tool 24. When the engagement pin biased upward (in the protruding direction) is retracted by the rotation of the lever 24c, The swivel plate 18 can swivel with respect to the one support plate 19, and the first fall prevention arm 15 can swivel in a horizontal plane around the swivel shaft 22.
[0013]
As shown in FIGS. 1, 2, 11, and 12, a pair of support plates 25 are fixed to the rear end portion of the first fall prevention arm 15 at predetermined intervals in the vertical direction. ing. The base end portion of the second fall prevention arm 16 is bent at an obtuse angle, and the base end portion of the second fall prevention arm 16 is disposed outside the rear end portion of the first fall prevention arm 15, The support plate 25 is inserted between the support plates 25 and supported by the pair of support plates 25 via the support pins 30 so as to be pivotable. The urging cylinder 26 is a cylinder in which the rod 26 a is urged in the retracting direction, and the base end portion of the urging cylinder 26 has a support pin 27 at the free end portion of the second fall prevention arm 16. The tip of the rod 26a is supported on the pair of support plates 25 via a support pin 28. For this reason, the second fall prevention arm 16 can be rotated only outward from the return position against an urging force to rotate inward. As shown in FIG. 2, the second fall prevention arm 16 crosses at an obtuse angle with respect to the straight portion 15 b of the first fall prevention arm 15 and faces obliquely rearward at the return position. A fall prevention frame 29 is also fixed to the second fall prevention arm 16. In FIGS. 1 and 2, reference numeral 31 denotes a wheel of the roll baler body 1.
[0014]
In the roll baler body 1, as described above, after the grass that has been dried and picked up in the field is picked up and formed into a strip shape, the strip-shaped grass is formed into a column shape and the roll bale R is made. As shown in FIG. 13, the center axis C of the roll bale R is substantially parallel to the field scene G. When the rear case 3 is opened in this state, the elevating rod 7 is raised via the pair of connecting rods 8, and the kicker 5 fixed to the elevating rod 7 at the front end thereof is attached to the body frame 4. (See FIGS. 1 and 14). The inclination angle of the kicker 5 has such a size that the roll bale R is discharged rearward without being influenced by the inclination angle along the front-rear direction of the roll baler body 1.
[0015]
When the roll bale R is released from the roll baler body 1 and rolls on the kicker 5 in the backward tilted position, one end portion in the central axis direction collides with the reversing pole 12 to roll the roll bale R. While the movement is stopped, the roll bail R immediately after the collision receives a reaction force locally from the reversing pole 12 at one end in the central axis direction. Moreover, since the other end portion of the roll bail R in the center axis direction at the time of the collision is on the side of the kicker 5 and is located at a predetermined height from the field scene G, the roll bale is caused by the reaction force. One end portion in the central axis direction of R is pushed forward and the other end portion is further moved rearward, whereby the roll bale R has a circular shape at the other end portion in the central axis direction with the inversion pole 12 as a fulcrum. The plane portion is inverted so as to contact the farm scene G (see FIGS. 2 and 15). Here, since the anti-slip projection 6 is provided on the upper surface of the kicker 5, the roll bale R released from the roll baler body 1 and rolling on the kicker 5 does not slide laterally. Since the posture is not lost along the central axis direction (left-right direction) immediately after the release of the roller, and the anti-slip protrusion 14 is provided at the contact portion of the reverse pole 12 with the roll veil R, the roll during the reverse motion The bail R does not shift in the direction of the central axis, and the reversal motion is performed reliably.
[0016]
The roll bale R during the reversing motion may be reversed beyond 90 ° due to its inertial force. In this case, the roll bale R collides with one of the first and second fall prevention arms 15 and 16 and slightly reverses (returns) in the opposite direction, so that the circular flat portion is in the field. It stands still in the field scene G in the standing posture in contact with G (see FIG. 16). In this way, the roll bale R is prevented from overturning, and the roll veil R can be surely placed on the field scene G in a standing posture with the circular plane portion down. Even so, the released roll bale R can be reversed and allowed to stand in a standing posture where the circular flat portion is in contact with the farm scene. Here, when the roll bale R is going to reverse more than 90 ° obliquely rearward due to the inertial force of the roll bale R during the reverse movement, the second fall prevention arm provided with the urging cylinder 26 is provided. As shown by a two-dot chain line in FIG. 11, the arm 16 pivots outward against the urging force of the urging cylinder 26, and the energy of the roll bale R during the reversing motion Therefore, a large impact force is not applied to the support portion at the base end portion of the first fall prevention arm 15 and this portion is protected.
[0017]
Moreover, since the stand position of the roll bale R with respect to the roll baler body 1 is immediately after the roll baler A in operation, the roll bale R that is left standing in the field G in a standing posture does not interfere with the next roll bale operation. .
[0018]
Furthermore, when the roll baler A is carried into or out of the field, the first and second fall prevention arms 15 and 16 extending rearward of the roll baler body 1 may become an obstacle. However, in this case, as shown in FIG. 17, the first and second fall prevention arms 15, 16 are swung around the swivel shaft 22 by the operation of the engagement tool 24 and stored. It should be in a state.
[0019]
【The invention's effect】
The present invention is a structure in which a discharge device having a simple configuration mainly including an inversion pole and an overturn prevention arm and not including a power drive unit is integrally incorporated in the rear portion of the roll baler body, and thus has the following effects. Is done.
(1) The roll bale released from the roll baler body can be reversed only by the energy of the movement and position of the roll bale when it is released, and allowed to stand in a standing posture on the field scene. Thus, since the discharge device according to the present invention does not have any power drive unit, the configuration thereof is simple and the manufacturing cost is low. Furthermore, since the discharge device according to the present invention is integrated into the rear portion of the roll baler body, the length of the roll baler body does not need to be unnecessarily increased, and the discharge device does not hinder grass harvesting work.
(2) Since the roll bale to be reversed over 90 ° by the inertia force at the time of reversal collides with the fall prevention arm and is prevented from overturning, the roll bale can be reliably reversed by 90 °. For this reason, the roll bale can be reversed not only in a horizontal field but also in an inclined field. In this case, when the fall prevention arm is divided into two along the longitudinal direction and the two are crossed obtusely, the roll veil falls only in the lateral direction by the rear part of the two divided fall prevention arms. It is also possible to prevent the vehicle from falling backward.
(3) Since the reversal pole which becomes the reversal fulcrum of the roll bale is disposed at one end in the width direction of the roll bale body, the stationary position of the reversed roll bale is almost immediately after the roll bale body. For this reason, the stationary roll bale does not become an obstacle of the next roll bale operation.
(4) If the fall prevention arm is structured to be able to turn, the fall prevention arm can be folded along the width direction at the rear of the roll baler body when it is not in use and when it is carried into and out of the field. Don't be.
