Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides an automatic self-removal type combine harvester that includes:
This invention relates to a waste straw sorting device in a waste straw bundling device that ties waste straw in appropriate amounts after harvesting and threshing and releases it into a field or the like.

[Conventional technology]

Conventionally, in this type of waste straw binding device, while the waste straw is being transferred along the upper surface of the guide deck plate in a direction perpendicular to the culm direction, the waste straw is
After converging to an appropriate size using a packer placed below the guide deck plate, the string is passed through a needle placed below the guide deck plate and a knot placed above the guide deck plate. The bundled waste straw is bundled by the swinging movement of a discharge arm provided above the guide deck plate.
For example, a configuration in which the light is emitted from the end along the guide deck plate is disclosed in Japanese Utility Model Application Publication No. 53-139969.
It is well known as described in the publication No.

[Problem to be solved by the invention]

However, since the waste straw that is transferred along the upper surface of the guide deck plate is intertwined with each other at the base of the pile, unlike the conventional waste straw binding device, the discharge arm for the bundled waste straw is If the device is placed on the tip side of the waste straw, it will not be possible to completely separate the bundled waste straw and untied waste straw, even down to the base of the bundle. Since the bundled waste straw is released while being entangled with the stock part, not only is it not possible to release the bundled waste straw smoothly, but also the stock part of the bundled waste straw to be released as described above is not placed at the bundling position on the guide deck plate. Untied waste straw entangled in the straw would be pulled out, scattering it over the field, or hindering the next bundling process.

In addition, in order to prevent this problem,
Publication No. -45719 uses a sorting arm that rotates around an axis perpendicular to the culm direction of the straw to remove the tangles at the base of the straw that is transferred along the upper surface of the guide deck plate. proposed to remove the tangles by squeezing the stem part of the waste straw in the direction of its culm. Not only do they fall off from the waste straw in large quantities and impede the rotation of the sorting arm, but also the position of sorting by this sorting arm coincides with the separation position of the bundled waste straw and the unbound waste straw. It is extremely difficult.

The present invention aims to solve the above-mentioned problems in this type of straw binding device.

[Means to solve the problem]

In order to achieve this object, the present invention provides a swing-type discharging arm for knotting and bundling straw above a guide deck plate that transports the straw in a direction perpendicular to the direction of the culm. On the other hand, in the waste straw binding device comprising a packer and a needle arranged below the guide deck plate, a separating shaft extending in the culm direction of the waste straw is arranged below the guide deck plate, and The sorting shaft is provided with a discharging and discharging discharging arm that protrudes above the guide deck plate at the stock end portion of the straw, and the discharging and discharging discharging arm is attached to the discharging arm. When the discharging arm moves in the direction of discharging the bundled waste straw, the discharging arm also protrudes from below the guide deck plate onto the guide deck plate, and then rotates in the direction of releasing the bundled waste straw. The relevant configuration was made to do so.

[Effect]

With this configuration, when the bundled waste straw is discharged by the swinging movement of the discharge arm, a sorting arm that also serves as discharge is provided on the guide deck plate in synchronization with the movement of the discharge arm. Because it protrudes, it is possible to reliably remove the entanglement of the stem part between the bundled waste straw and unbound waste straw, and then, by rotating the handling arm that also serves as a discharger in the direction of releasing the waste straw, the tangles in the bundle waste straw can be removed. The stock head is ejected in the same direction as the ejecting direction by the ejecting arm.

In other words, after the bundled waste straw is untangled with the unbound waste straw at the stock head by a handling arm that also serves as a discharge, the bundled waste straw is separated by a release arm at the tip of the ear and a handling arm that also serves as a release at the stock head. It is released by both.

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 indicates a conventionally known self-propelled, self-removal type combine harvester body, and a cover case 2 provided at the rear of the combine harvester has a feed chain (see the figure). The waste straw sent along the upper surface of the inclined guide deck plates 4 and 5 from the straw removal chain 3 connected to the straw removal chain 3 (not shown) is collected in an appropriate amount and then tied up.
A conventionally known straw binding mechanism 6 is provided for discharging straw in the rear direction along the guide deck plates 4 and 5.

This straw binding mechanism 6 includes a transmission case 7 with an L-shaped side surface, a bearing case 8 protruding from the upper side of the transmission case 7, and a knot attached to the tip of a knot shaft 9 pivotally supported within the bearing case 8. 10, an input shaft 11, a clutch shaft 12, and a door shaft 13, which are pivotally supported at the lower side of the transmission case 7 in parallel with the joint shaft 9.
The nodule section 10 includes a building 15 and a holder 16 driven by the nodule shaft 9, and the bearing case 8 has three discharge holes at appropriate intervals in the axial direction. Arm 17,1
8 and 19 are connected via a link 21, and the tip of a crank 22 fitted to one end of the nodal shaft 9 is pivotally attached to the bracket 20, so that rotation of the nodal shaft 9 causes each The distal ends of the ejection arms 17, 18, 19 are configured to swing in the direction of the arrow along a trajectory indicated by a chain double-dashed line 23 in FIG.

The focusing section 14 includes a packer 24 and a needle 2.
5 and a door 26, and the input shaft 11 is constantly driven to rotate by power transmission from the power source of the combine harvester. The packer 24 has its base end connected to the transmission case 7 via a curved link 27.
In addition, the tip of the crank 28 fitted to the tip of the input shaft 11 is pivoted, and the rotation of the input shaft 11 causes the tip of the packer 24 to move in the direction of the arrow along the locus shown by the two-dot chain line 29 in FIG. The proximal end of the needle 25 is rotatably supported by the door shaft 13, and the needle 25 is pivotally connected to the distal end of a crank 30 fitted to the distal end of the clutch shaft 12. Then, due to the rotation of the clutch shaft 12, the tip of the needle 25 is brought into contact with the building 1 at the knot 10.
5 to bind both ends of a string (not shown) previously passed through the needle 25 with the building 15, and the door 26
is fitted onto the door shaft 13 so as to protrude upward from between the guide deck plates 4 and 5.

A gear 32 that meshes with a gear 31 fitted on the input shaft 11 is rotatably fitted onto the clutch shaft 12 in the transmission case 7, and a clutch 33 is provided, and the clutch 33 and the door shaft are connected to each other. 1
3 is related via the clutch interlocking mechanism 34,
When the door 26 attached to the door shaft 13 rotates backward, the clutch 33 and the idler gear 32 engage with each other due to the action of the clutch interlocking mechanism 34, and the door shaft 13 begins to rotate, causing the clutch shaft 13 to complete one rotation. Then, the clutch interlocking mechanism 34 automatically disengages the clutch 33 and the free rotating gear 32, and the clutch shaft 12
The rotation of the chain 38 is transmitted from the sprocket 35 fitted on the clutch shaft 12 to the sprocket 37 of the intermediate shaft 36, while the transmission is transmitted from the sprocket 39 of the intermediate shaft 36 to the sprocket 40 on the joint shaft 9. When the clutch shaft 12 rotates once, the connecting shaft 9 rotates once and stops at the same time.

Then, a sorting shaft 42 is disposed substantially parallel to the input shaft 11 on the lower surface of the guide deck plate 4 at a portion of both the guide deck plates 4 and 5 through which the stem portion of the waste straw passes. The sprocket 43 inserted into the transmission case 7 and fitted to the shaft end is engaged with the power transmission chain 38 from the clutch shaft 12 to the intermediate shaft 36, thereby rotating the separating shaft 42 simultaneously with the clutch shaft 12. The handling shaft 42 is provided with a handling arm 44 which also serves as a discharger and which can protrude upward from the guide deck plate 4. When the arm moves backward from the solid line position to the two-dot chain line position in Figure 1 and moves forward from there, the guide deck plate 4 rises upward from below in synchronization with this and rotates in the same direction as each ejection arm. The phase timing is set so that

In this configuration, the straw sent out from the straw removal chain 3 to both guide deck plates 4 and 5 is transferred to the input shaft 1.
Due to the swinging motion of the locus 29 of the packer 24 due to the rotation of 1, the straw is successively focused on the front face of the door 26. By repeating this, the amount of collected waste straw on the front face of the door 26 increases, and when a predetermined amount is reached, the straw is focused on the front face of the door 26. rotates the door 26 backward through the converging straw, and as a result of the rotation of the door shaft 13 to which the door 26 is attached, the clutch 33 and the idler gear 32 engage, and the clutch shaft 12 begins to rotate. On the other hand, the door 26 is further rotated backwards and pulled in from the deck plates 4 and 5, and due to this rotation of the clutch shaft 12, the knot shaft 9 begins to rotate, and the needle 25 is moved to the clutch shaft 1.
The string passed through this is passed through the collecting straw by the upward movement toward the building 15 due to the rotation of the building 15, and then the both ends of the string are tied and tied by the building 15. Ejection arm 17,1 inside
8 and 19 move backward along the trajectory 23, and move forward when the bundling is completed, thereby discharging the tied waste straw to the rear along both deck plates 4 and 5.

When the bundled waste straw is discharged by the forward motion of each of the discharge arms 17, 18, 19, the discharging and handling arm 44 provided on the stock base side projects upward from below on the guide deck plate 4, and the above-mentioned Since it rotates in the same direction as the movement direction of the discharge arms 17, 18, and 19, the separating arm 44 can untangle the bundled waste straw and unbound waste straw at the base of the stock, and also remove the bundled waste straw. , each of the ejection arms 1
7, 18, 19 and a handling arm 44 which also serves as a discharge.

In this case, if two discharging and discharging discharging arms 44 are provided at appropriate intervals in the direction of the culm of the waste straw as shown in the above-mentioned embodiment drawings to form a dual dispensing discharging discharging disposing arm, the stock can be increased. Needless to say, the division can be handled more effectively.

〔Effect of the invention〕

As described above, according to the present invention, after the bundled waste straw is untangled with unbound waste straw at the stock head part by the discharging arm, the release arm at the tip part and the untied waste straw at the stock head part are removed. It can be discharged by both the discharging and sorting arm, and the bundled waste straw can be discharged after the bundled waste straw has been almost completely cleared compared to the unbound waste straw. Moreover, as the bundled waste straw is released, the unbound waste straw is not pulled out, unlike in the conventional method, where the unbound waste straw is scattered on the field or interferes with the next bundling. There is no such thing. Furthermore, since the bundled waste straw is discharged by both the discharge arm on the ear side and the handling arm that also serves as a discharger on the stock side, there is no change in the posture of the bundled waste straw during discharge, and the bundled waste straw is discharged. It has the effect of reliably releasing straw in a certain direction under a certain posture.
