The direction of rotation of the upper rotating body or the lower rotating body on the side of the guide rail is set so as to push toward the part.

According to the present invention, the protrusions protruding toward the guide rail are provided on the carriage at intervals along the moving direction of the carriage. As a result, when the carrier is driven to rotate while the root of the crop is sandwiched between the carrier and the guide rail, the projection of the carrier pushes the root of the crop.
As described above, when the base of the crop is sandwiched between the conveying body and the guide rail, when the projection of the conveying body pushes the base of the crop, the base of the crop comes into contact with the guide rail. It will be in a state of sliding on the guide rail.

A change section is provided.
As a result, when the root of the crop reaches the resistance change portion of the guide rail in a state where the root of the crop slides on the pressing portion of the guide rail and is pushed by the protrusion of the conveying body, the guide rail Since the resistance applied to the base of the crop is reduced (because it is increased), the crop is easily rotated around the horizontal axis passing through the stem of the crop. At this time, when the separating action of the separating portion is applied to the crop, the crop often rotates around a horizontal axis passing through the stem of the crop.
When the crop rotates as described above, the separating action of the separating part will be applied from one part to another part of the crop, and the separating action of the separating part will be applied to each part of the crop, so that Since the seeds can be separated without leaving any seeds, the performance of separating and collecting seeds from crops can be improved.
According to the present invention, in the separating section, the upper rotating body hits the upper side of the crop lying sideways, and the lower rotating body hits the lower side of the crop lying sideways.
Assuming that a guide rail is arranged along the upper side of the carrier, the lower side of the root of the crop comes into contact with the carrier, and the upper side of the root of the crop comes into contact with the guide rail. A certain upper rotating body hits the upper side of the crop lying sideways so as to push it toward the conveying start end side of the conveying body.
As a result, the upper rotating body on the guide rail side pushes the upper side of the crop lying sideways in the direction opposite to the conveying direction of the crop with respect to the conveying direction of the crop by the lower conveying body. rotates more often.

Contrary to the above-described configuration, the guide rail is arranged along the lower side of the conveying body so that the upper side of the root of the crop is in contact with the conveying body and the lower side of the root of the crop is in contact with the guide rail. Assuming that the lower rotating body on the side of the guide rail hits the lower side of the crop lying sideways so as to push it toward the conveying starting end of the conveying body. As a result, the lower rotating body on the guide rail side pushes the lower side of the crop lying sideways in the direction opposite to the conveying direction of the crop with respect to the conveying direction of the crop by the upper conveyor. rotates more often.

The parts of the upper rotating body and the lower rotating body on the conveying body side are located closer to the conveying starting end of the conveying body than the parts of the upper rotating body and the lower rotating body on the opposite side of the conveying body. and the upper rotating body and the lower rotating body are arranged to be inclined in a plan view with respect to the conveying body,
The upper rotating body and the lower rotating body are arranged such that the upper rotating body and the lower rotating body push the crop passing between the upper rotating body and the lower rotating body toward the conveying starting end side of the conveying body. The direction of rotation is set and
The rotational phase of the upper rotating body and the rotational phase of the lower rotating body are set so that the upper rotating body and the lower rotating body alternately hit the crop passing between the upper rotating body and the lower rotating body. It is preferable to have

According to the present invention, when the upper rotating body and the lower rotating body collide with the crop passing between the upper rotating body and the lower rotating body, the crop is crushed while the base of the crop is sandwiched between the conveying body and the guide rail. A component of force is generated to pull out the stock from the stock base side (conveyor side) toward the upper side.
As a result, the crop is not compressed toward the base of the plant, buckled and bent, and the fruit can be separated from the crop without difficulty.

The upper rotating body hits the upper side of the crop lying sideways so as to push it toward the starting end of the conveying body, and the lower rotating body hits the lower side of the lying crop so as to push it toward the starting end of the conveying body. .
In this case, the direction in which the crop is rotated by the upper rotor and the direction in which the crop is rotated by the lower rotor are opposite to each other. , the action of the upper rotating body to rotate the crop and the action of the lower rotating body to rotate the crop cancel each other out.

According to the present invention, the upper rotating body and the lower rotating body alternately hit the crop passing between the upper rotating body and the lower rotating body (because they do not hit the crop at the same time), so the upper rotating body acts to rotate the crop. It is possible to avoid a state in which the action of the lower rotating body to rotate the crops is offset with each other, and a state in which the crops can be sufficiently rotated can be obtained without difficulty.

The root A1 of the crop A is clamped by a sufficient clamping force.

When the second conveying body 9 is rotationally driven in a state in which the root A1 of the crop A lying sideways is sandwiched between the second conveying body 9 and the guide rail 13, the second conveying body 9 is rotated. The first projection 31a of the first portion 31 and the second projection 32a of the second portion 32 push the root A1 of the crop A rearward.

As a result, while the upper side of the root A1 of the crop A slides along the lateral sides 41b and 41c of the first rail portion 41 and the lower side of the second rail portion 42, the root A1 of the crop A moves rearward. The crop A enters the separating section 5 through the opening 30 of the separating section 5 and is conveyed from the conveying starting end 9a of the second conveying body 9 toward the conveying end 9b.

As shown in FIGS. 13 and 14, when the root A1 of the crop A reaches the rollers 33 of the guide rails 13, the root A1 of the crop A moves from the first portion 31 and the second portion 32 of the second conveying body 9. , and the roller 33 of the guide rail 13 . As a result, the resistance applied from the guide rail 13 to the root A1 of the crop A is reduced, so that the crop A can easily rotate about the horizontal axis passing through the stem of the crop A.

(State in the separation section (first upper rotating body and first lower rotating body, second upper rotating body and second lower rotating body) in the flow of the entire harvest of the green soybean harvester)

As shown in FIG. 7, the striking portion 19 of the first upper rotating body 11 and the striking portion 19 of the first lower rotating body 12 alternately hit the crop A, and the crop A is conveyed by the second conveyor 9. The fruits A2 are separated from the crop A and dropped onto the recovery conveyor 10 in a state of being pushed toward the starting end 9a (see the above-mentioned (Structure of Separating Section)).

Next, the crop A enters between the second upper rotating body 21 and the second lower rotating body 22 . The hitting part 19 of the second upper rotating body 21 and the hitting part 19 of the second lower rotating body 22 are alternately and repeatedly hit against the crop A, and the crop A is pushed toward the conveying start end 9a of the second conveying body 9. In this state, the fruit A2 is separated from the crop A and dropped onto the collection conveyor 10. - 特許庁

As shown in FIG. 3, the first upper rotating body 11 and the first lower rotating body 12 are inclined with respect to the second carrier 9 at an angle B1. A second upper rotating body 21 and a second lower rotating body 22 are inclined with respect to the second conveying body 9 at an angle B2.
As shown in FIG. 7, a rotation direction C1 of the first upper rotor 11 (second upper rotor 21) and a rotation direction C2 of the first lower rotor 12 (second lower rotor 22) are set. .

As a result, when the striking part 19 of the first upper rotating body 11 (second upper rotating body 21) and the striking part 19 of the first lower rotating body 12 (second lower rotating body 22) hit the crop A, the crop A A component of force is generated to pull out the crop A from the side of the base A1 (the side of the second carrier 9) toward the upper side while the base A1 of the plant is sandwiched between the second carrier 9 and the guide rail 13. As a result, the crop A is not compressed to the side of the root A1 and buckled and bent, and the fruit A2 is separated from the crop A without difficulty.

The action of rotating the crop A in the rotation direction C3 causes the roller 33 to rotate in the rotation direction C4, and the crop A is often rotated in the rotation direction C3.

In this case, since the lower side of the root A1 of the crop A is conveyed rearward while being in contact with the second conveying body 9 (the first portion 31 and the second portion 32), the crop A is moved in the rotation direction C3. The action to rotate the crop A is opposite to the conveying direction of the crop A, and the rotation of the crop A in the rotation direction C3 is promoted.

As shown in FIG. 14 , in a state where the root A1 of the crop A is sandwiched between the first portion 31 and the second portion 32 of the second conveying body 9 and the roller 33 of the guide rail 13, the first The hitting part 19 of the lower rotating body 12 (second lower rotating body 22) pushes the lower side of the crop A lying sideways toward the conveying start end 9a of the second conveying body 9 while rotating in the rotation direction C2. When it hits, the impact portion 19 of the first lower rotating body 12 (second lower rotating body 22) acts to rotate the crop A in the rotation direction C5.
The action of rotating the crop A in the rotation direction C5 causes the roller 33 to rotate in the rotation direction C6, and the crop A is often rotated in the rotation direction C5.

As described above, when the crop A rotates in the rotation directions C3 and C5, the hitting portion 19 of the first upper rotor 11 (second upper rotor 21) and the first lower rotor 12 (second lower rotor) The hitting part 19 of 22) hits each part of the crop A, and the crop A is separated without leaving the fruit A2.
