Description

[Detailed description of the invention] The present invention has a structure in which a receiver that receives a stem culm in a horizontal position is configured to intermittently release the stem culm by downward swinging and return to the receiving position after release. The receiver is provided with an auxiliary bone on the free end side of the tool so that the tool can swing vertically relative to the tool, and as the tool swings, the auxiliary bone forcibly swings the tool relative to the tool. An interlocking mechanism is provided, and the relative position of the auxiliary bone is changed so that the tool has its free end side facing upward in the receiving position of the tool, and the receiver faces downward in the releasing position of the tool. The present invention relates to a stem culm focused discharge device configured to be used.

In this type of device, the above-mentioned auxiliary bone is used to ensure that the pedicle culm is received by the tool, and the auxiliary bone is designed so that the tool does not interfere with the release of the pedicle culm. Since the angular velocity of the tool is constant, the auxiliary bone cannot sufficiently reduce the resistance to the tool flowing down the stalk culm when the pedicle culm is released, and the auxiliary bone is unable to sufficiently reduce the resistance of the tool to the lower part of the culm when the tool returns. There was a problem that the auxiliary bone caught the ejecting pedicle culm by the tool when it started to swing upward.

In view of the above points, the present invention allows the auxiliary bone to be smoothly released from the stem culm without loosening by simply adding a simple improvement to the drive configuration of the tool, and the auxiliary bone can be used to move the ejecting stem culm to the tool. The purpose is to prevent hooking as much as possible.

Next, embodiments of the present invention will be described in detail with reference to the drawings.

A vertical conveyor device 4 delivers the cut stem culms to a feed chain 3.
A threshing device 5 that performs threshing while holding and transporting the stalks, a cutter 6 that shreds the stalk culms after the threshing process, and a stalk culm that intermittently releases a predetermined amount of straw into the field as long straw without shredding. The focusing and discharging device T is successively installed on a traveling trolley equipped with a crawler traveling device 8 and a control section 9, and as it travels, it can continuously harvest and process planted stems and culms in the field. Configure the combine as follows.

The stem culm focusing and discharging device 7 has an auxiliary support 11 pivotally connected to the free end side of the support 10, and a pivot shaft 12 fixed to the support 10 connected to the cutter 6. It is pivotably connected to a case 13 which has an interior therein.

Then, by an operation from the control unit 9, the receiver is operated via the attitude change mechanism 14, which switches between a posture in which the tool 10 is placed in a substantially horizontal position and the stem culm is received in a horizontally suspended position, and a vertical storage position along the rear surface of the case 13. Fixed member 1 interlockingly connected to the case 13 side
5 is pivotally supported on the pivot shaft 12, and a tension spring 16 is interposed between the rod 15a connected to the fixing member 15 and the tool 10, and the urging force of the spring 16 causes the receiver to hold the tool 10 in the stem. In order to maintain the culm-receiving attitude, the receiver is configured to return to the culm-receiving attitude after the tool 10 swings downward to discharge the culm.

The support member 17 that receives the gravity of the stem culm on the tool 10 is pivoted on the pivot shaft 12, and the fixed member 15 and the support member 17, and the first link 18a and the second link 18b are pivoted relative to each other. The receiver is connected via a bending and swinging link 18 which is freely pivotally connected, and as the stem culm gravity acts on the tool 10, the support member 19 connected to the tool 10 moves to the first link 18.
a is configured to swing by pressing the first link 18a and the fixed member 15, and the first pivot point S1 of the first link 18a and the fixed member 15 and the second
The third pivot point S3 of both links 18a and 18b is located on the extension line connecting the link 18b and the second pivot point S2 of the support member 17, and the receiver controls the downward swinging of the tool 10 so that the stem culm gravity is at the set value. so as to prevent it by a tensioning action until the
When the stem culm gravity exceeds the set value, the suppression member 1
The rotational force applied from 9 to the first link 18H acts as a dog due to the tension force at the third pivot point S3 and the accompanying static friction force, forcing the first link 18a to swing, and the tension action is released. The receiver 10 rapidly swings downward,
The receiver is configured to intermittently release a predetermined amount of the stem culm received on the tool 10.

The support member 17 has a compression spring 2 on its roadside side.
The receiver is connected to the fixture 10 through an adjustment bolt 21 with a screw inserted therein, and by adjusting the bolt 21, the support member 17 is swung around the pivot shaft 12, and the receiver is moved closer to or closer to the fixture 10. , a pressing force from the suppressing member 19 that changes the position of the second pivot point S2 and releases the tensioning action of the bending swing link 1B;
That is, the stem culm gravity adjustment mechanism 2 is used to change and adjust the stem culm gravity.
It consists of 2.

The suppressing member 19 is screwed onto the receiver 10 so that it can be screwed on, and adjusts the pressing position of the first link 18a and the initial posture of the first link 18a to release the tensioning action. In other words, the receiver is configured to adjust the timing at which the tool 10 starts discharging the stem culm received by it, and to finely adjust the stem culm gravity required to release the tensioning action. It is configured to act as part of the gravity adjustment mechanism 22.

The first link 18a and the auxiliary support 11 are connected to the rod 2.
3, and as the tensioning action of the swing link 18 is released and the receiver 10 swings downward, the first link 18a moves forward with respect to the receiver 10. Accordingly, the auxiliary receiver 11 swings relative to the tool 10, and changes from an upward position where it catches the stem culm to a downward position where the receiver is connected almost in a straight line to the tool 10 in order to release the stem culm. is configured to automatically and reversibly change.

The first link 18a is rapidly swung at the same time as the holder 10 starts to swing downward as the tensioning action against the gravity of the stem culm on the holder 10 is released, and as shown in FIG. At the beginning of the downward swing, the receiver assumes a downward posture that is connected to the tool 10 in a substantially straight line, and in this state, the receiver moves toward the tool 10.
It is constructed so that it swings downward in unison with the

When returning to the receiving posture, the receiver swings upward integrally with the tool 10 in the initial stage, and the auxiliary receiver and the tool 11 rapidly swing upward from an intermediate point.

In the figure, reference numeral 24 denotes a tension spring for returning the swing link 18 to the tensioning position and returning the auxiliary receiver 11 to the stem culm receiving position.

The auxiliary receiver includes the first link 18a and the rod 23, which allow the tool 11 to swing up and down relative to the receiver tool 10, and are collectively referred to as an interlocking mechanism 25.

In addition, the above-mentioned auxiliary cost is not limited to those that swing the tool 11 and the receiver all the way to the tool 10, but in short, even if the receiver spans the full swing width of the tool 10, the upper side, That is, at the beginning of the downward swing, the support cost for the support tool 10 is sufficient as long as the angular velocity of the tool 11 is set to a constant value.

In summary, the structural features of the present invention are as follows.

A support member 17 that elastically supports the receiver 10 that receives the stem culm in a horizontal posture is attached to a fixed pivot shaft 12 similar to the receiver 10, and the support member 17 is pivoted downward from the receiving posture. The bending swing link 18a is used to prevent the
, 18b are pivotally connected between a fixed first pivot point S1 different from the fixed pivot shaft 12 and the support member 17, and the bending swing link 18at18 is fixed with a fixed receiving stem culm weight.
In the stem culm focused discharge device configured to discharge a fixed amount by releasing the tensioning action of b, and to automatically elastically return to the stem culm receiving posture by a spring 16, the receiver is the device 1.
An auxiliary tool 11 is pivotally mounted on the free end side of 0, and the link 18a on the fixed first pivot point S1 side among the bending swing links 18a and 18b and the auxiliary tool 11 are interlocked via a rod 23. and the auxiliary material is in a state where the free end side of the tool 11 is facing upward in the receiving posture of the tool 10, and
The receiver is configured so that its relative position can be changed to a state in which the tool 10 is directed downward when the tool 10 is discharged, and the auxiliary cost is such that the angular velocity of the receiver of the tool 11 relative to the tool 10 is as high as possible, and the receiver is as large as possible to the joist above which the tool 10 is located. It is characterized by the following structure, and this provides the following effects.

In other words, at the time of releasing the stem culm, at the initial stage, the auxiliary device causes the tool 11 to swing significantly relative to the receiver tool 10, so that the receiver accelerates the movement of the stem culm on the tool 10 to the free end side. It can be flowed down rapidly and released smoothly in a predetermined amount of concentrated state.
On the other hand, when the receiver returns to the stopped position, by reducing the rocking of the auxiliary tool 11 at the initial stage, it has been possible to suppress the catching of the discharge stem culm as much as possible.

In particular, the present invention focuses on a link mechanism for quickly releasing the supporting function of the tool 10 while the auxiliary cost sets the angular velocity of the tool 11 as described above, and the support is a component of this mechanism. The link 18a and the auxiliary component simply interlock the tool 11 via the rod 23, and are set by effectively utilizing the operation of the mechanism itself. The structure does not require any special mechanism and is extremely advantageous in terms of manufacturing and cost.
