BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll baler having a compression chamber defined by rollers arranged in a ring.

[0002]

2. Description of the Related Art As shown in FIG. 4, a roll baler 1 has a fixed frame 3 and a movable frame 4 forming an outer shell. Rollers 5 driven in the same rotation direction and having a predetermined length in the axial direction are provided on the side walls of the fixed frame 3 and the movable frame 4.
Are arranged in an annular shape, and the compression chamber 2 is sectioned in a cylindrical shape by the rollers 5. An inlet 6 is formed between the rollers 5 so as to be open at a predetermined interval and to introduce an object g such as grass and rice straw scattered in a field or the like into the compression chamber 2.

The fixed frame 3 is mounted on traveling wheels 7, and a tow rod 8 for connecting to a tractor (not shown) is attached to the front of the fixed frame 3 in the traveling direction. A pick-up device 9 for picking up the workpieces scattered thereon while traveling is provided, and a cutting device 10 for cutting the picked-up workpiece g into a predetermined size. The cutting device 10 is interposed between the pick-up device 9 and the introduction port 6, and forms a conveyance path between the pickup device 9 and the introduction port 6, and extends along the conveyance direction of the bottom plate 12. A large number of cutting blades 1 protruding from the bottom plate 12
3 is provided.

On the upper part of the cutting device 10, there is provided a transfer finger 14 which is rotated between the cutting blades 13 and cuts and conveys a workpiece g interposed between the cutting blades 13 to a predetermined size. The transfer rotor 1 implanted on the rotating shaft
5 are provided. The cut workpiece g is urged by the transport fingers 14 as it is, and is introduced into the compression chamber 2 from the inlet 6 opening toward the transport path formed by the bottom plate 12.

The rollers 5 forming the compression chamber 2 are driven in the same rotational direction, and a plurality of ridges 16 are implanted on the surface thereof along the longitudinal direction. That is, the compression chamber 2
Is rotated along the inner peripheral surface of the compression chamber 2 formed by the rollers 5. The roll bale r that rotates along the inner peripheral surface of the compression chamber 2 and is formed into a columnar shape along the shape of the compression chamber 2 initially rotates only by its own weight, and is a swelling material having a low compression density. However, as the inside of the compression chamber 2 is sufficiently filled with the objects to be treated g sequentially introduced from the introduction port 6, the surface layer portion of the roll bale r and the ridge 16 of the roller 5 repeatedly engage with each other, and the roll Since the air filling the void inside the bale r is squeezed out, and the object to be processed g itself is also compacted,
The surface layer is formed into a roll bale r which is hard and has a high compression density.

[0006]

By the way, the roll bale r is rotated by transmitting its rotational driving force from a surface in contact with the roller 5 and a ridge 16 planted on the peripheral surface of the roller 5. However, there is a difference in the rotation speed between the roll bale r and the roller 5 due to slipping on the contact surface and the ridge 16, and the rotation speed of the roller 5 is higher,
The roller 5 rubs the surface of the roll bale r. That is, the ridges 16 implanted on the surface of the roller 5 bite into the surface layer of the roll bale r to damage the surface layer, thereby generating small pieces c of the workpiece g, or forming a relatively short piece. It would pull the object to be processed g ₁ from the surface layer portion.

[0007] or strip c is generated, it is withdrawn from the object to be treated g ₁ is the surface layer portion, but this is not as long as the problem of staying in the compression chamber 2, in the form as follows, the strip c When it is attached to the roller 5 and discharged to the outside or the ridge 1
In some cases, a problem may be caused because the sample may be discharged to the outside. That is, the lower roller 5B of the rollers 5 forming the inlet 6 of the roll baler 1 rotates from the inlet 6 side toward the inside of the compression chamber 2, while the upper roller 5A rotates toward the compression chamber 2 side. since rotating outwardly from, or strip c and the object to be treated g ₁ is conveyed as it is outside the inlet port 6 is rotated to adhere to the roller 5A,
The protrusion 16 scrapes out the inlet 6 and is deposited near the inlet 6.

On the other hand, the workpiece g which is urged by the transport fingers 14 and reaches the inlet 6 includes a roller 5B rotating inside the compression chamber 2 from the inlet 6 side and a roller 5B.
B can be introduced into the interior by the occlusal force when it is thrown into the occlusal portion formed by the roll bale r that is driven to rotate by B or the like. short and Saegigi is to deposit the object to be processed g _1, the object to be treated is urged by the transport fingers 14 g
Cannot remove the deposits such as the small pieces c and cannot reach the bite portion. In addition, since the workpiece g is sequentially transported by the transport fingers 14, once the flow is obstructed, the clogging phenomenon of the inlet 6 is immediately caused, and the operation of the roll baler 1 becomes impossible.

The roller causing the clogging phenomenon of the inlet 6 is only the roller 5A, and the small pieces c and the like generated on the roller 5 other than the roller 5B or the roller 5A adhere to the roller 5. Even if the roller 5 is rotated outward, it is pushed back into the compression chamber 2 by the inward rotation of the roller 5 adjacent to the roller 5 and is prevented from being discharged to the outside, so that the problem of the roller 5A does not occur. .

[0010] The above problem is that the object g to be processed is
Degree to be cut smaller, etc., since projection body 16 or scraping the relatively short treatment object g ₁ or to generate a large amount of strip c may dig into the surface of the roll bale r, particularly remarkable However, it is also a problem that generally occurs when cutting is not performed finely.

Therefore, the present invention effectively solves the above-mentioned problems, solves the phenomenon of clogging of the object to be processed by strips near the inlet, and provides an excellent roll baler which enables a smooth roll bale forming operation. The purpose is to provide.

[0012]

In order to achieve the above-mentioned object, the present invention is directed to an axial direction in which one or more ridges are implanted in the longitudinal direction of the peripheral surface while being driven in the same rotational direction. Rollers having a cylindrical shape formed by arranging rollers having an annular shape and forming an inlet for introducing an object to be processed into the compression chamber with a predetermined interval between the rollers, The surface of a roller that forms an inlet and rotates outward from the compression chamber side is formed as a smooth surface. In addition, a scraper may be provided on the peripheral surface of the roller having the above-mentioned surface formed as a smooth surface, with its tip slidably contacting or approaching.

[0013]

With the above arrangement, the roller which forms the inlet and rotates outward from the compression chamber side has a smooth surface, so that the surface layer of the formed roll bale is damaged and the surface of the roll bale is damaged. No small pieces are generated, a relatively short object to be processed is not scraped off from the surface, and no clogging phenomenon is caused in the inlet. In addition, the scraper scrapes off the workpiece sporadically adhering to the surface of the roller to maintain a smooth surface.

The transport rotor 15 has transport fingers 14 that are implanted at predetermined intervals along the rotation axis and project radially outward. Further, a scraper 19 for scraping off the processing object adhered to the rotating shaft between the transfer fingers 14 and an arm member 2 for supporting the scraper 19 on a side plate provided below the fixed frame 3.
0. At the lower part of the transfer rotor 15, a bottom plate 12 that is located slightly below the lowermost end of the rotation locus drawn by the tip of the transfer finger 14 and forms a transfer path for the workpiece from the pick-up device 9 to the lower part of the fixed frame 3. Are supported by side plates provided below the fixed frame 3.

As shown in FIG. 2, the bottom plate 12 is provided with a large number of slits 21 which are opened at predetermined intervals in the direction of transport of the workpiece. Further, a guide member 22 for the cutting blade 13 having a pivot shaft 29 that protrudes from the narrow gap 21 and rotatably supports the cutting blade 13 that blocks the conveying direction of the workpiece is provided below the bottom plate 12. ing. The guide member 22 of the cutting blade 13 is provided with a spring 23 that absorbs the impact of the cutting applied to the cutting blade 13 when the workpiece is cut finely. On the side walls of the fixed frame 3 and the movable frame 4, the compression chambers 2 are formed in a cylindrical shape by arranging the rollers 5 on which the ridges 16 are planted in a ring shape, and a predetermined space is provided between the rollers 5. An inlet 6 of the compression chamber 2 for introducing the object to be processed is formed at an interval of.
The introduction port 6 is open toward a bottom plate 12 that forms a transport path for the object to be cut in order to introduce the object to be cut.

In particular, the present invention is characterized in that, among the rollers 5, the inlet 6 is formed, and the roller 51 which rotates outward from the compression chamber 2 side is formed to have a smooth surface. Further, a scraper 24 for scraping off the processing object adhered to the surface of the roller 51 is provided.

The scraper 24 is formed of a plastic material, has a wide trapezoidal shape on the side in contact with the roller 51, and is formed so as to be in flexible contact with the roller 51. Fifteen
The scraper 19 for scraping off the workpiece adhered to the rotating shaft of the scraper 19 is used, and the adjustment of the mounting position of the scraper 24 with respect to the roller 51 is performed by the scraper 19.
Loosen a plurality of bolts of the bracket 25 provided on the head of
This is performed by moving the scraper 19 in the up-down direction and refastening with the bolt 26. Incidentally, the scraper 24 may be an elastic material such as steel or rubber.

Next, the operation of the embodiment of the present invention will be described.

The roll baler 1 is connected to the tractor by a towing rod 8 and is activated by transmitting power from the PTO shaft of the tractor, and then is towed by the tractor to form the scattered objects on the field into a roll bale. The object travels toward the objects scattered in the field, and is picked up by the rotating fork 18 of the pick-up device 9. The picked-up workpiece is guided by a rotary fork 18 toward a bottom plate 12 of a cutting device 10 interposed between the pick-up device 9 and the inlet 6.

Here, the object to be processed, which is blocked by a large number of cutting blades 13 provided along the bottom plate 12 and protruding therefrom, is transferred to the transport finger 1 rotating in the gap between the large number of cutting blades 13.
4 and is cut and urged on the cutting blade 13 by its rotary hitting force. The energized workpiece is the bottom plate 1
2 and is sequentially introduced into the inlet 6 of the compression chamber 2 which opens toward the bottom plate 12. The workpiece introduced into the compression chamber 2 is loaded on the rollers 5 and conveyed in a certain direction because all the rollers 5 forming the compression chamber 2 in a cylindrical shape are driven in the same rotation direction. Will be. The workpieces loaded on the rollers 5 are conveyed in a ring shape and given a rotational motion because the rollers 5 are arranged in a ring shape. The object g, which has been given a rotational movement inside the compression chamber 2, is urged by the transfer fingers 14 and introduced, even if it becomes large enough to block the inlet 6 of the compression chamber 2. Can be introduced from the inlet 6 into the inside.
This is because the object to be processed is introduced and bite into an occlusal portion formed by contacting the object to be rotated and the roller 5 forming the inlet 6 so as to bite. Further, when the weight of the object to be processed given the rotational motion is sequentially increased by the object to be processed g sequentially introduced from the occlusal part, the rollers 5 are firmly arranged to form the compression chamber 2. Therefore, the object to be processed is shaped with its outer shape regulated along the shape of the compression chamber 2. That is, the object to be processed is squeezed out of the air occupying the internal space, the object to be processed itself is compacted, and the surface layer of the object to be processed is deformed toward the inside. By such a function of the compression chamber 2, a columnar roll bale having a high compression density and a firm surface layer is formed.

In particular, in the present invention, of the rollers forming the inlet 6 of the compression chamber 2, the surface of the roller 51 rotating outward from the compression chamber 2 side is formed smoothly, so that the roll bale is made smooth. The surface portion of the roller 51 is only deformed inward by being pressed against the surface of the roller 51, and the surface portion is not scraped off even if a difference in rotation speed appears between the roller 51 and the roll bale. The reason why only the surface of the roller 51 is smoothed is that the other roller 5 has the adjacent roller 5 in the rotation direction of the object to be processed, so that the small piece is not discharged to the outside due to being hindered by this. is there. In other words, in the strip attached to the roller 5 other than the roller 51, in the portion adjacent to the adjacent roller 5 positioned in the rotation direction of the roll bale, the rotation from the outside of the adjacent roller 5 to the inside of the compression chamber 2 is caused by the rotation. The rotational movement of the strip directed outward from the compression chamber 2 is pushed back inside.

Further, since the scraper 24 is provided for scraping off the small pieces sporadically adhering to the surface of the roller 51 when the roller 51 is rotated, the surface of the roller 51 is kept smooth.

As described above, the roll baler 1 of the present invention can form a roll bale smoothly without causing clogging of the object to be processed in the vicinity of the inlet 6, and when the roll bale reaches a predetermined compression density, it is fixed. The movable frame 4 pivotally supported by the frame 3 is expanded upward by the hydraulic cylinder 28 and is appropriately discharged to the outside of the compression chamber 2, whereby a series of operations can be smoothly performed.

In this embodiment, the case where the scraper 24 is attached to the head of the scraper 19 has been described. However, as shown in FIG.
Needless to say, a scraper 27 having an L-shaped cross section may be attached to scrape the small pieces attached to the peripheral surface of No. 1.

[0028]

[Effect of the Invention] As is apparent from the above description, the present invention exerts the following excellent effects.

(1) Since the introduction port of the compression chamber is formed and the surface of the roller rotating outward from the compression chamber side is formed as a smooth surface, no small pieces are generated on the surface layer of the roll baler, and A relatively short object to be processed is not scraped out, and clogging which hinders the introduction of the object to be processed is prevented at the inlet, so that a smooth compression-compression molding operation is achieved.

(2) According to the configuration in which the scraper is provided on the roller having a smooth surface, the processing object adhering sporadically to the surface can be scraped off, and the smooth surface of the roller can be maintained.
