JP 2017-035014 A

As shown in the above-mentioned Patent Document 1, in the structure having a plurality of receiving members extending to the front side of the cutting device, when the harvesting part scrapes the planted crop, the tine that acts as a rake Even if the crops that come in contact with the stalks fall off and fall off, the crops can be received and collected by multiple receiving members, causing the harvested object to fall to the ground on the front side of the cutting device, causing loss. This is useful in that it is possible to significantly reduce the possibility of occurrence.
However, with this structure, even if the crop is received by the receiving member once, it was received on the receiving member when changing the running posture of the aircraft or performing cutting work with a slightly lower cutting position. There is a possibility that crops may fall to the front side of the aircraft and become uncollectable, and there is room for improvement in this regard.

  The present invention is intended to provide a harvester that can further suppress the loss of the harvested object in the harvesting section.

  A feature of the present invention is a harvesting machine provided with a harvesting unit that harvests planted crops while scraping planted crops at the front of the machine body, the harvesting unit having a tine that acts on the planted crops A plurality of reels, a cutting device for cutting planted crops, a deck for receiving the cut crops, a plurality of portions extending above the cutting device to the front side of the cutting device and spaced in the cutting width direction The receiving member is provided with a stopper portion that restricts the movement of the crop received by the receiving member to the front side of the machine body.

According to this configuration, when the harvesting part scrapes the planted crop, even if the harvested object that has come into contact with the tine that acts as a stirrer is detached from the planted crop, the harvested object remains on the ground on the front side of the cutting device. Before falling, it is received by the receiving member.
And even when the received harvested object is about to roll down to the front side of the traveling machine body, the receiving member is provided with a stopper portion that restricts the movement of the received crop to the front side of the machine body. Therefore, since the movement of the harvested object can be stopped and the falling-off can be suppressed, there is an advantage that the loss of the harvested object can be further suppressed.

  Furthermore, in the present invention, it is preferable that the stopper portion is provided on the front side of a range where the tine scratching action locus exists.

  According to this configuration, the harvested object can be received on the receiving member even in a range where the tine scratching action does not reach. And if the receiving member changes its posture backward and downward due to a change in the running posture of the aircraft or a change in cutting height with a cutting device, the harvested object is easily moved back and sent into the tine scrambling range Therefore, the loss of the harvested object can be further reduced.

  Furthermore, in the present invention, it is preferable that the receiving member includes a tapered portion at a front portion, and the stopper portion is provided on the tapered portion in the front-rear direction.

  According to this configuration, the harvesting object received on the receiving member is stopped at the limit position so that the harvested object does not fall off either from the front side of the machine body or between the receiving members at adjacent positions. By positioning the portion, it is possible to maximize the range of restraining the cropping object from dropping by the stopper portion.

  Furthermore, in the present invention, it is preferable that the stopper portion is constituted by a protruding member erected on the upper surface of the receiving member.

  According to this structure, a stopper part can be comprised with the simple structure which attaches a protrusion member.

  Further, in the present invention, the stopper portion includes a front inclined surface having a rearwardly inclined surface, and a rear inclined surface having a rearwardly inclined surface located on the rear side of the front inclined surface, and from the front inclined surface. Also, it is preferable that the rear inclined surface is formed to be steeply inclined.

  According to this configuration, since the rear inclined surface is formed to be steeper than the front inclined surface, it is easy to suppress the movement of the harvested object from the rear side to the front side. In addition, if the inclination from the front side to the rear side, which is the reverse direction, is gentle, the possibility that the harvested object located on the front side of the stopper part can get over the stopper part increases, and the loss of the harvesting object is further reduced. There is a possibility that it can be reduced.

  Furthermore, in the present invention, it is preferable that the side surface along the front-rear direction of the stopper portion includes an inclined surface that extends downward.

  According to this configuration, when the stem portion of the planted crop passes between the receiving members, the possibility that the stopper portion is caught by the planted crop and disturbs the posture of the planted crop can be reduced.

  Further, in the present invention, the tine that moves in the direction along the longitudinal direction of the machine along with the rotation of the scraping reel is operated to scrape and intersects the plane in the longitudinal direction along the direction of the scraping movement and the direction of the scraping movement. Before and after sandwiching the tine from both sides in the front-rear direction by a mounting bracket that connects one end of the tine in the longitudinal direction to the scraping reel. It is formed in a channel shape having a pair of mounting piece portions, and the left and right surfaces of the tine are connected to one mounting piece portion in the front-rear direction of the mounting bracket by a connecting bolt, and the other side of the mounting bracket It is preferable that a portion of the tine in the front-rear direction surface at a position away from the left-right direction surface is connected to the attachment piece portion by a connection bolt different from the connection bolt.

According to this structure, in a structure in which a tine having a T-shaped cross section is bolt-connected to a mounting bracket formed in a channel shape, the tine connection portion is not easily rattled at an early stage due to a load at the time of scratching acting on the tine. It is easy to reduce the possibility of occurrence of the problem of loosening.
For example, in a state where one end side of a tine having a T-shaped cross section is inserted into the channel-shaped space of the mounting bracket, the connecting bolts positioned on both sides along the front-rear direction surface of the tine span a pair of front and rear mounting pieces. Compare with the structure provided in the state. In this structure, the connecting bolts extending over the pair of front and rear attachment pieces are tightened in a direction to draw the pair of front and rear attachment pieces together so as to embrace a T-shaped tine.
In this connected state, the load at the time of scraping acting on the free end side of the tine tends to act in the direction of widening the distance between the pair of front and rear mounting piece portions with respect to the bolt connecting portion. On the other hand, the tightening action of the connecting bolt works in a direction against a load in the direction of widening the interval between the mounting piece portions. For this reason, the load at the time of scraping acting on the free end side of the tine repeatedly acts in the direction opposite to the direction in which the connecting bolt is tightened, that is, in the direction in which the tightening of the connecting bolt is loosened. Bolt loosening may occur.
In contrast, in this configuration, the tine having a T-shaped cross section is connected to a mounting piece portion on one side in the front-rear direction of the mounting bracket on one end side in the front-rear direction with a connecting bolt, and attached on the other end side. It is connected to a mounting piece portion on the other side of the metal fitting by another connecting bolt.
Therefore, even if the load at the time of scraping acting on the free end side of the tine repeatedly acts in the direction of widening the distance between the pair of front and rear mounting pieces, the mounting bracket formed in a channel shape is applied to the load. Since it resists itself and the load at the time of scratching acting on the tines does not act directly on the individual connecting bolts, there is little possibility that the connecting portions by the separate connecting bolts are loosened.

The distance from the position to the front and back is increased so that the ground height increases sequentially. As described above, the heights of the divided cover bodies 50a, 50b, 50c, 50d, and 50e are different from each other in the case where the machine body is on the upper side in the forward direction in both forward and backward movements. This is to increase the height so that the guidance of the residue can be performed smoothly.

  Further, the foremost divided cover body 50a and the divided cover body 50b connected to the rear side thereof are joined together so that the front part of the rear side divided cover body 50b overlaps the upper side of the rear part of the foremost divided cover body 50a. is there. This is to prevent the stumps and weeds that are in sliding contact with the bottom cover 50 from being caught by the joining portions when the aircraft is moving forward. For the same reason, the rear divided cover body 50e and the divided cover body 50d connected to the front side of the rear divided cover body 50d are in a state where the rear part of the front divided cover body 50d overlaps the upper side of the front part of the rearmost divided cover body 50a. They are connected. This makes it difficult for stem stumps, weeds, and the like that are in sliding contact with the bottom cover 50 to be caught by the joining points when the aircraft is moving backward.

Among the divided cover bodies 50a, 50b, 50c, 50d, and 50e, the divided cover bodies 50b, 50c, and 50d that are present at particularly low positions are provided with an opening 51 with a lid that can be opened and closed.
Therefore, when dust or the like is accumulated, the lid-attached opening 51 can be opened and the dust or the like can be dropped, so that compared with the case where each of the divided cover bodies 50a, 50b, 50c, 50d, and 50e is attached and detached. Thus, the dust can be easily removed, and the cleaning work can be easily performed. The opening and closing operation of the opening 51 with the lid is a state in which the position of the Glen tank 6 that is configured to be able to be opened and closed by swinging left and right around the rear vertical axis (not shown) is changed by swinging to an open posture. Can be done.

As shown in the partially enlarged view in FIG. 20, in the lidded opening 51, one end side 51b in the left-right direction of the lid member 51a sinks below the split cover body 50b, and the other end side 51c is split cover body 50b.
