Description

  The present invention relates to a roll baler carrying device for a roll baler that is attached to a roll baler used in a forage crop harvesting work system.

  The forage crop harvesting system is a combination of mowing (or picking up after cutting), packing, transporting, and sealing, so there are a wide variety of types of working machines that are difficult to work with. Is the cause of the decline. For this reason, it is necessary to improve the work efficiency by methods such as improving the structure of the work machine and increasing the number of functions.

  Conventionally, a roll bale picked up and packed by a roll baler after cutting down with a mower etc. (cut and packed in a roll baler with a mowing function) is released and left on the field where it is packed, and then rolled. Lapping is carried by a dedicated transport vehicle such as a tractor with a club or a roll bale transporter (for example, see Patent Document 1 below) or a self-propelled lapping machine (for example, see Patent Document 2 below) having a pick-up function. Has been made.

  On the other hand, what is described in the following patent document 3 is proposed as what does not use such an exclusive conveyance vehicle.

  FIG. 1 is an explanatory view showing this prior art. This prior art is a trailer that can receive a roll of wheat, pasture, etc. rolled up by a self-propelled baler or a baler J1 pulled by a tractor, and can transport it to a certain place and discharge it, and is connected to the baler J1. A trailer J2 is formed from a main body J4 and a roll receiver J5 on which a roll J3 such as grass is placed. The roll receiver J5 can swing back and forth via a hydraulic cylinder J8 on a frame J7 having wheels J6 on both sides of the main body J4. The roll receiver J5 is swung backward by ejecting the hydraulic cylinder J8, and the roll J3 is discharged backward, and the roll receiver J5 is returned to its original state by expanding and contracting the hydraulic cylinder J8. It is something to return.

  According to such a conventional technique, a trailer connected to the rear of the roll baler can receive one roll bale discharged from the roll baler, and can be unloaded after being conveyed to an arbitrary position. Moreover, the roll bale can be efficiently transported without interrupting the cutting or picking up operation with the roll baler.

  However, according to the above-described prior art, since the roll receiver J5 is swung by the operation of the hydraulic cylinder J8, there is a problem that it cannot be installed in a feed rice harvester or the like that does not have an external hydraulic supply system. In addition, since it is a large machine that handles heavy roll bale by hydraulic pressure, the equipment itself has become large and heavy, and there is a problem that it has to be expensive equipment.

  The present invention has been proposed to cope with such a problem, and can be easily installed in a harvesting machine for feed rice that does not have an external hydraulic supply system, and has a special driving power. Roll baler transport device for roll baler that can be inexpensively equipped with a simple structure and light weight that does not require, and can efficiently transport the roll bale without interrupting the cutting or picking work with the roll baler Is intended to provide.

  In order to solve such a problem, the present invention is a roll baler roll baler carrying device that receives a roll baler that is mounted on a roll baler and that is discharged from the roll baler and carries the roll baler according to the movement of the roll baler. A main frame having a parallel frame with a front end pivotally supported on a horizontal shaft provided below the discharge port and extending rearward, and a grounding ring capable of changing the direction around the vertical axis on the rear end side, and the parallel frame A front frame portion which is pivotally supported around a horizontal axis provided therebetween and which can be formed in the same plane as the main frame inside the main frame on the front side of the shaft support portion; A rear frame portion that rises in a curved shape to receive the roll bale discharged from the rear discharge port of the roll baler on the rear side from A frame, and a load receiving guide that guides a roll bale that is supported at a position below the rear discharge port and is discharged from the rear discharge port onto the load frame. It is on the front side from the support part, and in the state where the roll bale is received at the rear frame part, the center of gravity position with the weight of the roll bale added is pivotally supported so as to be located on the rear side from the shaft support part, and And a holding mechanism for automatically holding the front end portion of the cargo bed frame at a position where the main frame and the front frame portion are in the same plane, and a holding release means for releasing the holding mechanism. To do.

  In addition to the above-described features, the holding release means can be remotely operated from the roll baler or a driver's seat of a traveling vehicle that pulls the roll baler.

  According to such a feature, the roll bale discharged from the rear discharge port of the roll baler is guided by the load receiving guide and transferred onto the load frame, and is received by the rear frame portion of the load frame. In this state, the roll baler can be moved to carry the roll bale to an arbitrary position, and the carrying can be performed while continuing the cutting or picking up of the roll baler.

  When the roll baler reaches a predetermined position, when the holding release means is operated to release the holding of the cargo bed frame from the main frame, the rear frame portion on which the roll bale is placed is caused by the weight of the roll bale and the loading frame. Since it swings and rotates so as to fall backward, the roll bale falls from the rear end of the rear frame portion and is unloaded onto the ground.

  When the roll bale on the loading frame is unloaded, the loading frame is held by the main frame by the holding mechanism at a position where the front frame part is lowered by its own weight and the front frame part forms the same plane as the main frame. As a result, it again waits to receive the roll bale.

  According to the roll bale transporting device having such a configuration, the roll bale discharged from the roll baler can be received and unloaded without requiring a special driving force. You can return to the waiting state.

  Since the present invention has such a feature, it can be easily installed on a harvester for feed rice that does not have an external hydraulic supply system, and has a simple structure that does not require special drive power. The weight reduction enables inexpensive equipment, and the roll bale can be efficiently transported without interrupting the mowing or picking up operation with the roll baler.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 2 and 3 are explanatory views showing the overall configuration of the roll bale transport device according to the embodiment of the present invention (FIG. 2 is an overall perspective view, FIG. 3 (a) is a side view, and FIG. 3 (b)). Is a plan view).

  A roll bale carrying device 2 according to an embodiment of the present invention is mounted on a roll baler 1, receives a roll bale R discharged from the roll baler 1, and carries it according to the movement of the roll baler 1. Consists of a main frame 10, a cargo bed frame 20, a cargo receiving guide 30, a holding mechanism 40, and a holding release means 50.

  The main frame 10 includes a parallel frame 11 having a front end pivotally supported by a horizontal shaft 3 provided below the rear discharge port 1A of the roll baler 1 and extending rearward, and can be changed in direction around the vertical shaft 13 on the rear end side. A grounding ring 12 is provided.

  The loading frame 20 is pivotally supported around a horizontal axis 14 provided between the parallel frames 11, and can form the same plane as the main frame 10 inside the main frame 10 in front of the pivotal support portion 21.

The guide rollers 32 arranged in a possible manner are horizontally supported.

  The load carrier frame 20 has its own center of gravity (the load carrier frame 20 alone) on the front side (roll baler 1 side) with respect to the shaft support portion 21, and in the state where the roll bale R is received by the rear frame portion 23, The center of gravity with its own weight is pivotally supported so that it is located on the rear side of the pivotal support portion 21. Further, the main frame 10 is provided with a holding mechanism 40 that automatically holds the front end portion of the cargo bed frame 20 at a position where the main frame 10 and the front frame portion 22 are flush with each other, and the holding release that releases the holding mechanism 40 is released. Means 50 are provided.

  In the roll bale transport device 2 having such a structure, the main frame 10 is supported at the front end by a horizontal shaft 3 extending in the width direction of the roll baler 1 and is centered on the horizontal shaft 3 as shown in FIG. Can be swung in the vertical direction, but is fixed in the horizontal direction. Further, since the grounding wheel 12 whose direction can be changed around the vertical axis 13 is provided on the rear end side of the main frame 10, as the roll baler 1 moves, it moves while following the unevenness of the running surface by swinging up and down. be able to. Further, when the roll baler 1 is turned, the grounding wheel 12 can move in a changed direction while being fixed to the roll baler 1.

  The loading frame 20 is pivotally supported so that the front frame portion 22 rotates in the direction in which the front frame portion 22 is lowered by its own weight, and the front end portion is held by the holding mechanism 40 at a position where the front frame portion 22 is flush with the main frame 10. Therefore, when nothing is placed, the front frame portion 22 is held at a position where it is flush with the main frame 10.

  When the roll veil R is placed on the rear frame portion 23 of the load carrier frame 20, the center of gravity position of the roll veil R with its own weight moves rearward from the shaft support portion 21, so that the load carrier frame 20 is the rear frame. Although the portion 23 is biased in the downward direction, the holding mechanism 40 holds the front end portion of the loading frame frame 20 against this biasing, and the front frame 22 is flush with the main frame 10. The carrier frame 20 is held at the position. Accordingly, when the holding mechanism 40 releases the holding mechanism 40 in this state, the rear frame portion 23 is rotated in a lowering direction without using any special power, and placed from the rear end of the rear frame portion 23. The rolled roll bale R will roll off.
