  By the way, when picking up a crop with such a pickup unit, the following problems arise.

  That is, when picking up a crop left in the field, the crop is picked up by the tine 51, but the picked-up crop moves backward while being placed on the tine 51. However, when the tine 51 is moved in a state where it is placed on the tine 51 in this way, as shown in FIG. 6, when the tine 51 inclined downward enters the slit 53, the crop is dragged into the slit 53 together with the tine 51. End up.

  Therefore, the present invention has been made paying attention to the above problems, and an object of the present invention is to provide a roll baler which prevents a crop from being dragged into a slit of a tine cover when picking up a crop with a pickup section.

That is, in order to solve the above-mentioned problem, the present invention projects a tine from a slit formed between tine covers, and picks up crops in a field by rotating the tine, and the pickup unit picks up the crop. the crop by rotating the rotating member in a direction to remove from the tine comprises a scrape-section scraped crops, and in roll baler which is adapted to shape the bale by scooped up crop in this該掻top, the tines Each rotation region is overlapped so that a position in front of the top of the rotation region is placed in the rotation region of the rotation member, and the crop on the tine facing upward is inclined by the rotation member. Scraping up along the direction .

In such an invention, the rotation region of the rotating member is provided above the upper surface of the tine cover.

According to the present invention, a tine protrudes from a slit formed between tine covers, and a pick- up unit that picks up crops in a field by rotating the tine, and a crop picked up by the pick-up unit from the tine. A roll baler that rotates a rotating member in a removing direction to scrape up the crop , and forms a roll bale by the crop scraped up by the scraper above the top of the rotation area of the tine. Each rotation region is overlapped so that the front position is placed in the rotation region of the rotation member, and the rotation member scrapes up the crop on the tine facing upward along the inclination direction of the tine. This ensures that the picked-up crop can be removed from the tine. Emissions can be prevented not dragged crops into the slit when entering the slit.

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

  As shown in FIG. 1, the roll baler 1 in this embodiment is configured to remove the crops picked up by the tine 22 from the pickup portion 2 that picks up crops in the field by rotating the tine 22 and the tine 22. The upper part 3 is scraped up. Characteristically, the rotating member 31 constituting the upper portion 3 is disposed so as to overlap the tine rotation region 2A, and the tine is rotated upward (in the same direction as the rotation direction of the tine 22). 22 crops can be removed from above. Hereinafter, the structure of the roll baler 1 in this Embodiment is demonstrated in detail.

  First, the pick-up unit 2 provided on the front side of the roll baler 1 is for picking up crops that have been cut and left on the field. As shown in FIG. 22 and a tine cover 23 covering between the tines 22 adjacent to each other in the rotation axis direction. In FIG. 2, the tine 22 is attached to the outer peripheral portion of the rotating drum 21 in a state where the free end side is slightly inclined from the rotating direction. By rotating the rotating drum 21, crops in the field can be obtained. It is going to be scraped up. When such a rotating drum 21 is rotated, the tine 22 rotates at the rear portion with the free end side facing downward. On the other hand, the tine cover 23 prevents crops from entering between the adjacent tines 22, and the tine 22 that circulates in the front portion protrudes from the slit 24 and the tine 22 in the rear portion. 22 enters the inside of the slit 24. Here, when the tine 22 is circulated, the tine 22 is circulated by rotating the rotary drum 21, but by providing a cam, the tine 22 is caused to enter the slit 24 while standing up. Various structures may be used.

  On the other hand, the scraper 3 is configured so that the crop picked up by the tine 22 can be removed from the tine 22. The scraper 3 includes a rotating member 31 composed of a pair of triangular blades facing each other with a slight gap, and is cut by sandwiching a crop with a fixed blade 32 provided thereabove. I can do it. Further, as shown in FIG. 1, a scraper 33 is provided between the rotating member 31 and the rotating member 31 so as to come into contact with the rotating shaft of the rotating member 31. To be discharged.

  The roll forming unit 4 forms a cylindrical roll bale from the crop cut in this way. Various configurations can be adopted as the roll forming unit 4, but in FIG. 1, a cylindrical roll bale is formed by a crop placed on the belt 41 by rotating the belt 41 in a circular shape. Like to do. As other methods, for example, a method of forming a roll bale by rotating a chain with a tight bar attached thereto, or rotating a plurality of drums arranged in a circle, respectively, by rotating the drum. A method of forming a roll bale can also be employed. Then, the crop is rotated by rotating these belt 41, tight bar, drum and the like, and the roll bale is enlarged while winding the crops discharged one after another around the outside. And when it becomes a predetermined magnitude | size, a net | bowl is discharged | emitted from the rear chamber 42, after extending | stretching a net | network from the net | feeding-out part 43 as needed and winding it around an outer peripheral part and cut | disconnecting the net | network.

  A description will be given of a state in which the pickup unit 2 and the upper portion 3 overlap in such a configuration.

  FIG. 3 shows a state in which the rotation area 2A of the tine 22 of the pickup unit 2 and the rotation area 3A of the scraper 3 are overlapped. The tine 22 of the pickup unit 2 is provided so as to protrude from each slit 24, while the rotating member 31 of the scraper 3 rotates between the tine 22 and the tine 22 (see FIG. 2). The regions 2A and 3A are provided at overlapping positions. Thereby, even if each tine 22 and the rotation member 31 are rotated, they are prevented from interfering with each other. As the overlap amount, the rotation regions 2A and 3A are overlapped within a range of 30% to 100% from the tip side with respect to the length of the portion where the tine 22 protrudes from the slit 24. Is preferred. That is, if only the tip end side of the tine 22 is overlapped, the crop present at the base portion of the tine 22 may be dragged inside the slit 24 and may be wound around the rotary drum 21. For this reason, it is made to overlap within the range of 30%-100% from the front end side.

  Further, when removing the crop from the tine 22 in this way, if the crop is to be removed with the free end side of the tine 22 facing downward, the rotating member 31 is applied in a direction perpendicular to the inclination angle of the tine 22. As a result, a large load is applied to the tine 22 and the rotating drum 21. Therefore, as shown in FIG. 4, the rotating member 31 is applied upward in a state where the free end side of the tine 22 is facing upward, whereby the crop carried by the tine 22 is obliquely upward (rectangular in the figure). It can be removed in the direction of the arrow.

  Next, the operation of the pickup unit 2 and the scraper 3 configured as described above will be described.

  First, when the roll baler 1 is caused to travel, crops in the field are picked up by the pickup unit 2. At this time, the crop is picked up from the field by the tine 22 rotating upward, and the crop moves along the surface of the tine cover 23 while being placed on the tine 22. On the other hand, the tine 22 enters the inside of the slit 24 on the rear side of the tine cover 23 so that crops in the field can be picked up again.

  On the other hand, the crop picked up by the tine 22 contacts the triangular rotating member 31 immediately before the tine 22 enters the inside of the slit 24. Then, the crop is picked up obliquely upward by a rotating member 31 that rotates upward, and the crop is sandwiched between the fixed blade 32 provided above and cut.

  Then, the crop cut in this way is discharged to the roll forming unit 4 along the upper surface of the scraper 33.

  On the roll forming unit 4 side, a roll veil is formed by the crop cut in this way. When this roll veil is formed, it is placed on a belt 41, a tight bar, or a drum that circulates in a circumferential shape, and the crops that are sequentially discharged while being rotated are wound around the outside and enlarged. When the roll diameter reaches a predetermined size, the net is fed out from the net feeding portion 43 to enter the gap between the roll bale and the belt 41, the net is wound and cut, and then the rear chamber 42 is opened to open the roll. Release the veil.

Thus, according to the above-described embodiment, the pickup unit 2 that picks up crops in the field by projecting the tine 22 from the slit 24 formed between the tine covers 23 and rotating the tine 22, and the pickup And a scraper 3 that rotates the rotating member 31 in a direction to remove the crop picked up by the section 2 from the tine 22 and scrapes the crop, and forms a roll bale by the crop scraped up by the scraper 3. In the roll baler 1 configured as described above, the respective rotation areas are overlapped so that the position in front of the top of the rotation area of the tine 22 enters the rotation area of the rotation member 31. crops on going on tines 22 as scraped along the inclination direction of the tine 22 Since, it is possible to remove the picked up crop from reliably tines 22, it can be prevented to enter the crop in the slit 24.

  In addition, this invention can be implemented in various aspects, without being limited to the said embodiment.

  For example, in the above embodiment, the scraper 3 is provided with the function of a cutting part, but it may be configured not to have such a function of the cutting part. In this case, for example, a linear member such as a brush or a metal wire may be rotated upward to supply the crop to a cutting unit provided separately.

  In the above embodiment, the rotary member 31 is rotated upward and cut by the fixed blade 32. However, the rotary member 31 itself may be provided with a blade so that the crop can be cut.
