Description

[Detailed Description of the Invention] The present invention relates to an aggregate compaction device for an aggregate transport vehicle that accumulates roughage such as grass, residual culms scattered in fields, wood chips, snow, etc.

In general, this type of collection is bulky, so in order to transport a large amount of collection at once, it is necessary to use a collection vehicle with a large platform capacity. Therefore, there has been a proposal to compress the accumulated material so that even a material transport vehicle with a small platform capacity can transport a large amount of material. It had a structure that compressed things from above and from the horizontal direction. Therefore, in the former case, in order to discharge the compressed material from the loading platform, a separate ejection mechanism must be provided, such as tilting the loading platform or installing a special ejection plate; In this case, it is possible to perform the discharge action using a compression plate that compresses in the horizontal direction, but in order to prevent the accumulated material thrown into the loading platform from scattering, a special cover is installed above the accumulated material input side of the loading platform. In any case, there was a drawback that the structure was complicated.

The present invention was devised in order to eliminate these drawbacks in view of the above-mentioned actual situation, and the present invention is a compression plate that compresses the accumulated material. It has a structure in which it rotates from the upper position on the pile input side on one side through the compression position to the discharge position on the other side, which not only compresses the pile but also prevents the pile from scattering. It can also perform the function of discharging accumulated materials,
The object of the present invention is to provide an aggregate compaction device for an aggregate transport vehicle that can simplify the structure and improve work efficiency.

The structure of the present invention will be explained based on the embodiment shown in the drawings. 1 is a running body of an accumulation vehicle for harvesting and transporting roughage such as grass;
On one side of the aircraft frame 1a, there is a driver's seat 2 in front,
Engine cover 3 is installed at the rear. On the other hand, on the other side of the fuselage frame 1a is a loading platform 4, which will be described later.
is mounted via a parallel link mechanism 5 so as to be able to rise and fall freely. 5a is a hydraulic cylinder for the parallel link mechanism 5, 6 is a driving operation panel, 7 is a crawler type traveling body, and 8 is an operating lever.

Reference numeral 9 denotes a reaping device disposed at the front end of the machine frame 1a in front of the loading platform 4. The reaping device 9 is configured to be able to rise and fall freely by a parallel link mechanism 10 equipped with a hydraulic cylinder 10a. Grass A cut by an up-cut type cutting blade 9a equipped on the carriage is guided by a chute 9b extending rearward and diagonally upward, and is discharged to the rear loading platform 4 side. Of the loading platform frames constituting the loading platform 4, a left-right support shaft 12 is supported at an appropriate position in the middle of an upper frame 11 provided on the upper edge side of the loading platform 4 and facing in the front-rear direction. 1
An arc-shaped bottom plate 13 curved in the front and back direction with the center of the bottom plate 13 having one side edge located forward of the loading platform front frame 11a, and extending upward to the front where the front part of the bottom plate 13 acts as a front plate of the loading platform 4, The other side edge is formed so as to be located at the position of the platform rear frame 11b on the stack discharge side. The rear plate 14 of the loading platform 4 is a loading platform rear frame 11b.
The actuating arm 14 is fixed to the support shaft 14a, which rotates rearward and upward from the rear frame 11b using the support shaft 14a supported at the upper end as a fulcrum.
The ammunition 15 interposed between b and the middle part of the rear frame 11b
is always biased towards the rear open side. 16
is a locking hook for locking the rear plate 14, and the locking hook 16 is attached to the rear lower surface of the bottom plate 13. In addition, 13a is an accumulated material inlet formed on the front side of the bottom plate 13, and is connected to the chute 9 of the reaping device.
The tip of the chute 9b is fitted so that the collected material B, such as grass, released from the chute 9b is thrown into the loading platform 4.

17, the tip side is bent inward in a substantially F-shape 1
7a, the compression plate 17 is configured such that its tip edge is rotatable in the front-rear direction along the arcuate bottom plate 13, using the support shaft 12 supported at the intermediate portion of the platform upper frame 11 as a fulcrum. However, due to the expansion and contraction of the hydraulic cylinder 18 interposed between the operating arm 12a fixed to the support shaft 12 and the intermediate vertical frame 11c of the loading platform 4, the compression plate 17 is moved up to the front upper edge position of the loading platform 4. From the elevated position where it rises to cover the upper part of the loading platform 4 on the stack B input side and become the ceiling plate of the loading platform 4, it passes through an appropriate compression position where the stack B stored in the loading platform 4 is compressed, and then further to the rear bottom plate 13. It is possible to freely adjust the rotation to the rear edge position, that is, to the discharge position where the compressed material B can be discharged from the loading platform 4.

Next, the operation of the present invention constructed as described above will be explained. First, in order to reap and harvest roughage such as grass using the traveling body 1, the rear side of the loading platform 4, which is locked with the rear plate 14 by the locking hook 16, is closed off, and the compression plate 17 is used to collect the loading platform 4. It is sufficient to run the reaping device 9 in the field while operating the reaping device 9 with the reaping device 9 placed in the raised position covering the upper part of the material input side and serving as a ceiling plate. That is, as the traveling machine body 1 travels, the grass A cut by the cutting blade 9a is discharged rearward and upwardly by the chute 9b, but immediately enters the input port 1.
3a into the loading platform 4 and are accumulated there.
At this time, the collected material B, which is forcefully thrown in from the chute 9b, is reflected and diffused by the compression plate 17 located in the raised position, guided toward the rear side of the loading platform 4, and is reliably accumulated inside the loading platform 4. . Therefore, the accumulated material B is guided and guided by the compression plate 17, and is accumulated sequentially from the rear side of the cargo platform 4 without scattering outside the loading platform 4. It can be used as a guide plate for prevention purposes. Moreover, in this case, since the distal end side bent portion 17a of the compression plate 17 faces rearward and upward along the discharge direction of the chute 9b, it acts as a guide for the loaded accumulation, and therefore, the higher the accumulation, the more the compression plate 17 It will be blown backwards along the
They can be evenly stacked up to the rear upper part of the loading platform 4.

When a suitable amount of the accumulated material B is collected in this manner, the machine stops traveling and the accumulated material B is compressed, and then the harvesting of roughage such as grass can be continued again. In order to compress the material B, when the hydraulic cylinder 18 is extended and the compression plate 17 is lowered from the raised position, the material B is sandwiched between the compression plate 17 and the rear plate 14 as shown in FIG. state and is compressed toward the rear side of the loading platform 4. Moreover, even in this compression operation, since the distal end side of the compression plate 17 forms the bent portion 17a as described above, the action of raking and compressing the accumulated material is performed extremely well. After that, when the hydraulic cylinder 18 is contracted and the compression plate 17 is placed in the raised position again, a collection space is formed on the front side of the loading platform 4, and it becomes possible to continue harvesting roughage such as grass.

On the other hand, in order to discharge the compressed material B from the loading platform 4, the locking hook 16 is removed and the ammunition 1 is removed.
The rear plate 14 automatically rotates rearward and upward under the biasing force 5, and the rear of the loading platform 4 is opened. Therefore, if the hydraulic cylinder 18 is extended longer than when the compression is activated in this state, the compression plate 17 is The compressed material B can be discharged by rotating further backward than the compressed position and pushing the compressed material B backward. In this way, in the present invention, the compressed aggregate B
can be discharged from the loading platform 4 using the compression plate 17 without providing a dedicated discharge plate or tilting the loading platform, and the aircraft structure can be simplified. Moreover, in the present invention, since the rear end of the bottom plate 13 is located above the position directly below the support shaft 12, there is an advantage that it is advantageous for discharging to a high place. Further, if necessary, by raising the entire loading platform 4 by operating the parallel link mechanism 5, it is possible to discharge the cargo to a higher location, such as a truck loading platform 19, as shown in FIG.

In the present invention, as shown in FIGS. 5 to 7, the front frame 11a, the rear frame 11b, and the intermediate vertical frame 11c are each connected via joint pins 20, so that the platform 4 can be used for By making it possible to divide the cargo platform 4a into which B is accommodated and the main body 4b into which the lower side of the cargo platform 4a fits, and by providing a locking hook 21 approximately on the center of gravity of the cargo platform 4a. If the loading platform 4 is appropriately raised by the operation of the parallel link mechanism 5, the locking hook 21 is engaged with the stand 22, and the parallel link mechanism 5 is lowered as it is, the accumulated cargo platform 4a is suspended and supported by the stand 22. It is separated from the carrier main body 4b in this state. Therefore, in this case, it is convenient to use the traveling vehicle 1 as a normal transport vehicle without the cargo platform 4a. This has the advantage that the reaping device 9 can be removably attached to the traveling machine body 1, and the traveling machine body 1 can be made multi-functional by making the pile loading platform 4a an option.

In summary, the present invention consists of a bottom plate of a loading platform mounted on a traveling aircraft body, which is an arc-shaped bottom plate that extends from the pile input side on one side of the loading platform to the pile discharge side on the other side, centered around a support shaft provided above the loading platform. At the same time, the loading platform has a compression plate whose tip side rotates along the arcuate bottom plate with the support shaft as a fulcrum, and the compression plate is rotated from a raised position covering the upper part of the pile input side on one side of the loading platform toward the lower side of the other side. Since it is rotatable to the position where it compresses the accumulated material and discharges it, the accumulated material that is thrown in from one side of the loading platform is compressed by the compression plate installed on the loading platform. However, the compression plate is
When loading material into the loading platform, it is located in a raised position that covers the upper side of the loading side, so that the accumulated material is not scattered outside the loading platform, but is reflected and diffused by the compression plate, and is evenly accumulated starting from the rear of the loading platform. , it is possible to perform the ideal accumulation and compression action on the loading platform using the compression plate. Moreover, since this compression plate rotates along the arcuate bottom plate from the compression position to the discharge position on the other side, the compression plate can be used to perform a discharge action. Therefore, although the compression plate has a simple structure in that it rotates along the arcuate bottom plate, it not only compresses the accumulated material, but also acts to guide the accumulated material to the loading platform and to guide the accumulated material to the loading platform. It is also possible to carry out the discharge action from the inside, simplifying the structure and improving work efficiency.
