Description

[Detailed Description of the Invention] The present invention relates to an auxiliary discharge device that is installed on the binding portion side of a binder and has the function of transporting grain bundles out of the machine.

The harvested grain culm is placed against the conveyor plate behind the cutting blade and transported to the binding section on one side of the machine for binding processing.
In a binder configured to discharge the bound grain culm bundles from the binding part to the outside of the machine, an auxiliary discharge conveyance tool connected to the lateral conveyance body of the conveyance plate part is provided extending outward from the machine body, and this conveyance is carried out. The structure is such that the upper part of the grain culm bundle is conveyed by the body to ensure that it is released outside the machine. If left as is, it will get in the way when moving between fields or storing it, so it is common practice to install an auxiliary ejection carrier so that it can be stored within the width of the machine. For example, Jikko 47-
Publication No. 33626, Publication No. 52-53636, Publication No. 33626, Publication No. 53636, Publication No.
There are those disclosed in Publication No. 50-34973 and the like.

By the way, among the known examples, the one seen in Japanese Utility Model Publication No. 47-33626 has an auxiliary conveyance body frame attached to a support part provided on the terminal side rotating shaft part of the main conveyance endless body in the conveyance plate part. The frame is supported so as to be slidable in the hand direction, and an endless belt is wound between wheels installed at both ends of the frame to form an auxiliary conveyance body.Therefore, the frame can be slid relative to the support part. Although it is possible to store the auxiliary transport body by doing so, it can only be stored to a position where the terminal end side of the main endless transport body and the outer end of the auxiliary transport body do not interfere with each other during the retracting movement. The auxiliary transport body cannot be completely retracted to the end, causing problems in various aspects such as danger avoidance.

In addition, in the device disclosed in Japanese Utility Model Publication No. 52-53636, the auxiliary conveyance device can be rotated and stored around the rotation axis on the terminal end side of the conveyance device in the conveyance plate section, so that it can be stored completely inside the machine. Although the above-mentioned problems will be eliminated if it is retracted, the power transmission to the auxiliary conveyance device is cut off when it is retracted. However, there is an inconvenience in that it is not possible to exert the conveyance effect.

Furthermore, in the device disclosed in Japanese Utility Model Publication No. 50-34973, the conveying device and the auxiliary conveying device are constructed by winding and hanging a single endless band, and the latter part corresponding to the auxiliary conveying device is Since it is constructed so that it can be folded and stored, this structure is also similar to the
Similar to the case of Publication No. 53636, it is inconvenient that no conveying action can be performed in the storage position.

In view of this situation, the invention of the present application was implemented, and while the belt with protrusions for auxiliary conveyance can be stored in a state where it is completely retracted from the side edge of the machine when stored, it can be moved back to the stored position when necessary. Even if there is a problem, the conveying device can be configured to perform a cooperating conveying action, thereby expanding the scope of its use.

Next, the embodiment shown in the drawings will be described.

FIG. 1 shows a perspective view of a multi-striped binder.
Dividers 4, 4', 4'' are installed on the left and right and in the middle at the frontmost part of the fuselage, which has both wheels 3, 3. Behind the left and right dividers 4, 4', there are lifting cases 5, 5', respectively. is installed diagonally, a cutting blade 1 is installed horizontally at the lower rear part of the cutting blade 1, and an inclined conveying plate A is installed horizontally at the upper rear part of the cutting blade 1, on which the cut grain culm is conveyed laterally while leaning on it. However, a binding part D, a discharge arm 6, etc. are installed on the lower side of the exit side end A, which is the right side of the conveyor plate A, and an engine E and a handle 7 are installed on the rear part of the machine, similar to the conventional structure. Configure.

Further, in the upper part of the conveyance plate A, a horizontal groove 8 is formed from the rear part of the left side drawer case 5 to the exit side end A, and the groove 8 is formed inside the groove 8 and at the rear of the conveyance plate A. A drive sprocket 9 is mounted on a shaft at the rear of the left end so as to be rotatably driven, and a shaft 1 supported on a bracket 10 is mounted on the outlet side end A.
A sprocket 12 is fitted to the upper end of the sprocket 1, and a chain-made carrier B with protrusions is placed around both sprockets 9 and 12. Protrusions 13 are attached to the carrier B at regular intervals.
is attached so that the protrusion 13 can move in a protruding state along the groove 8 to engage the grain culm.

Support plate 1 stretched above the projection-equipped carrier B
4 through a support metal 15, and the shaft 11 below the bracket 10.
A V-shaped pulley 16 is fitted to the lower end of the pulley 16, and support plates 17, 17 that can rotate coaxially with the pulley 16 extend from the top and bottom of the pulley 16, and the tips of the support plates 17, 17 are spaced apart. Pulley 18 mounted inside
Protrusions 19 are formed at regular intervals on the V-shaped belt C that is wrapped around the pulley 16, and split-shaped fasteners 20 are integrally provided below the bases of the support plates 17, 17 on the pulley 16 side. , the support money 15
A support shaft body 21 installed below is fitted into a clamp 20, and the clamp 20 is configured to be freely tightened by a screw 22 with a lever.

However, as shown in Figures 1 to 3,
When the belt C with protrusions is installed so as to extend outward from the machine body, the conveyor B and the belt C rotated by the sprocket 9 rotate as shown by the arrows in FIGS. 2 and 3, and during work. Grain culms leaning against the conveyor plate A while being cut by the cutting blade 1 are conveyed by the protrusion 13 of the conveyor B and reach the exit side end A side, where they are bound by the binding part D and then transferred to the belt C as they are. The protrusion 19 causes the liquid to be ejected to the side away from the outer part of the fuselage.

Also, loosen the screw 22 to rotate the support plates 17, 17 around the shaft 11, and pull the pulley 1 at the tip.
By rotating the 8 side about 180 degrees around the shaft 11, the belt C can be stored inside the groove 2 as shown in FIGS. When the screw 22 is tightened so that the grain culms are cut by the cutting blade 1 and leaning against the conveyor plate A during operation, the grain culms that are leaning against the conveyor plate A are exposed to the protrusions 13 of the conveyor B.
The protrusion 19 of the belt C also connects to the protrusion 13 as shown by the arrow in FIGS. While rotating in the same direction, they can be locked together and transported to the binding side.

In this case, if the protrusion 19 is set so as to retract inward from the groove 2 surface, the protrusion 19 of the belt C will not engage and the protrusion 13 of the conveyor B will carry the belt. In addition, the protrusions 19 and 13 can be opened with the belt C extended outward.
The degree of release can be changed by adjusting the protruding state of the.

In this way, the present invention allows the grain culms to lean against the transport plate A installed horizontally at the upper rear part of the cutting blade 1 and transport them to the binding part D side on the side of the machine body. Conveyor B with lateral protrusions up to the exit end
In the binder configured by rotatably mounting the conveyor plate A at a position near the protrusion-equipped conveyor B.
A horizontal groove 2 parallel to the protrusion-equipped conveyor B is formed in the part, so that the exit side end of the protrusion-equipped conveyor B and the inner end of the protrusion-equipped belt C can be driven to rotate coaxially. The belt C with protrusions is arranged so that it can be stored in the groove 2 by rotating from a position extending outward from the exit side end of the conveyor plate, and can be rotated and stored in the groove 2 with the shaft as the center. At the time, the belt with protrusions has a posture in which it performs a conveying action in the same direction as the conveyor body B with protrusions,
Since the protrusion 19 can be changed to a non-conveying position in which the protrusion 19 is moved back from the conveyor plate, there is no incompletely stored state that occurs in conventional systems in which the auxiliary conveyor belt is stored by sliding movement. As a result, it can be completely retracted and stored inside the aircraft, making it possible to accurately reduce the width of the aircraft and improve safety.

Furthermore, while the auxiliary conveyance belt can be completely retracted and stored, the auxiliary conveyance belt can be placed in the retracted position and in a conveying state, or in a non-conveying state, so that it can be adjusted to suit the field conditions. Depending on the crop conditions, the auxiliary conveyance belt that is parallel to the conveyance device of the conveyance plate section can be used to carry out the conveyance operation, so that the crop can be conveyed well.

There are some advantages.
