  The present invention relates to a harvester.

  For example, Patent Document 1 includes a pulling and holding conveyance device that pulls out green soybeans together with their roots by holding the green beans near the roots of the green soybeans from the left and right sides and conveying them backward and upward in the harvesting section of the green soybean harvester. Is disclosed.

JP 2004-105018 A

  Like the harvesting section described above, it has a harvesting section that lifts and conveys crops from the rice field to the rear and upwards, and is provided on the rear side of the harvesting section, inherits the crops from the harvesting section, and transports the inherited crops However, in a harvesting machine equipped with an intake processing unit that performs processing to the crop intake state, since the crop is transferred between the harvesting unit and the intake processing unit, dust such as dust is easily generated from the transferred crop. .

  The present invention provides a harvesting machine that can supply a crop from a harvesting unit to an intake processing unit with a simple transfer structure, but does not scatter in a wide range even if dust comes from the crop supplied from the harvesting unit to the intake processing unit. provide.

  The harvesting machine according to the present invention is supported by the front part of the traveling machine body, and is provided on the rear side of the harvesting part, and is provided on the rear side of the harvesting part, and is provided on the rear side of the harvesting part by lifting and conveying the crop from the rice field to the rear and upper side. And an intake processing unit for carrying out the inherited crop and processing the inherited crop to a state of taking in the crop, and a dust-proof cover for covering the movement path of the crop passed from the harvesting unit to the intake processing unit It has been.

  According to this configuration, the crop is supplied from the harvesting unit to the intake processing unit by passing the crop between the harvesting unit and the intake processing unit. Even if dust comes out from the crop delivered between the harvesting unit and the intake processing unit, the dust is prevented from diffusing by the dust cover.

  Therefore, even though the crop can be supplied from the harvesting unit to the intake processing unit with a simple transfer structure, even if dust comes out from the crop delivered between the harvesting unit and the intake processing unit, Don't scatter.

  In the present invention, there is provided a posture changing mechanism that is provided on the movement path, and that causes the crop to fall to the dust cover and changes the posture of the crop from a vertical posture at the harvesting unit to a laterally inclined posture for the intake processing unit. Provided, the dust cover has an upper side vertical cover part that covers the movement path from the upper side of the crop movement direction, and a lower side vertical cover part that covers the upper side of the movement path from the lower side of the crop movement direction, It is preferable that the upper-side vertical cover part is further away from the lower-side vertical cover part from the attitude changing mechanism to the tip side of the side-down posture crop.

  According to this configuration, the crop delivered from the harvesting unit to the intake processing unit is subjected to the posture change operation by the posture change mechanism, and the crop subjected to the posture change operation is subject to the upper vertical position while changing the posture from the vertical posture to the sideways posture. Passes between the cover part and the posture change mechanism and enters the inside of the dust cover, falls into the inside position of the dust cover and passes under the lower vertical cover part from the inside of the dust cover to the rear side of the dust cover Go out.

  The upper-side vertical cover part is farther away from the posture change mechanism to the tip side of the sideways posture crop than the lower-side vertical cover part, so the distance between the upper-side vertical cover part and the posture change mechanism is lower And when the crop passes between the lower-side vertical cover portion and the posture-changing mechanism, the crop is hardly caught on the upper-side vertical cover portion.

  Even if the lower-side vertical cover is located closer to the posture change mechanism than the upper-side cover, the crop passes under the lower-side vertical cover when it comes out of the dust cover. The lower vertical cover is less likely to become resistance. Since the lower-side vertical cover part is located at a position closer to the posture changing mechanism than the upper-side vertical cover part, the dust prevention cover effectively prevents dust from being scattered.

  Therefore, while allowing the crop to be delivered smoothly from the harvesting section to the intake processing section, even if dust comes out from the delivered crop, it is possible to prevent the emitted dust from spreading over a wide range.

  In the present invention, it is preferable that the dust cover can be switched between a use state and a storage state lower than the use state.

  According to this configuration, the dustproof cover is placed in a high usage state during work, and the crop supplied from the harvesting unit to the intake processing unit can hardly be resisted by the dustproof cover, but the dustproof cover is in a low storage state when not working. It is easy to store the harvester.

  In the present invention, it is preferable that the dust cover is foldable in the retracted state.

  According to this structure, it can store by simple storing operation which only folds a dust-proof cover.

  In the present invention, the dust-proof cover has a lower cover portion and an upper cover portion, and the upper cover portion is supported by the lower cover portion so as to be swingable up and down, and is lifted up and down with respect to the lower cover portion. It is preferable that the dustproof cover is switched to the use state, moved downward and swinged with respect to the lower cover portion, and the dustproof cover is switched to the retracted state.

  According to this configuration, the dust cover can be switched between the use state and the retracted state by a simple switching operation by simply swinging the lower cover portion.

  In the present invention, it is preferable that the harvesting unit is configured to harvest green soybeans, and the intake processing unit is configured to perform a dehulling process of green soybeans.

  According to this configuration, green soybeans can be harvested from the rice field with a simple harvesting structure, and the green soybeans are removed from the harvesting part with a simple transfer structure in which the green soybeans are only passed between the harvesting part and the pureing part. Even if dust comes out from the green soybeans delivered between the harvesting part and the dehulling part, the dust is not scattered over a wide range.
