Description

[Detailed explanation of the idea] The present invention relates to a combine harvester.

A large number of culm collection devices for combine harvesters have been proposed, but the present invention is particularly designed to drop the threshed culm in a fixed amount in the direction of the culm, and to adjust the mounting height of the culm collection member to the combine main body, that is, the height of the culm collection member. If the distance between the lowermost end of the floating end and the field surface is greater than the length of the culm, the culm will be ejected in a direction perpendicular to the direction of movement of the combine, and vice versa. When the length of the culm is large, the guide plate formed on the culm collector member is used to align and leave the culm in an upright state on the ground so as to tilt it down along the direction of movement of the combine. 2
To prevent a combine crawler from trampling the culm of a small combine harvester during cutting such as row cutting.

Further, in conventional cutters for combine harvesters, the waste culm is directly supplied to the cutter from the conveying mechanism to be cut, and the waste culm flow path to the cutter is closed to collect the waste culm.

Configuring such a treatment flow path for the exhaust culm only unnecessarily complicates the structure, and has the additional disadvantage of making the entire combine larger than necessary.

The present invention was developed in view of the above circumstances, and it eliminates the drawbacks of the conventional method with a simple structure, and provides a culm collection member at the first point in the discharge culm flow path to discharge the culm toward the culm. By placing a cylindrical cutter in a specific culm discharge channel of the culm collection member, the cutter mechanism is simplified compared to the conventional one, and the overall size of the combine is reduced.

To explain the details of the embodiment with reference to the drawings, 1 is a combine main body, 2 is a threshing device, 3 is a conveyance mechanism for the culm,
The harvested and threshed and adjusted waste culms are conveyed to the rear of the combine main body 1 so that the direction of the culms is orthogonal to the direction of movement of the combine harvester.

In such a combine, the present invention includes a spring 5 which is attached to the rear of the combine main body 1, one end of which is pivotally supported on a shaft 4 provided on the combine main body 1, and which is detachably stretched between the combine main body 1 and the combine main body 1. Accordingly, the culm collection member 6 having a self-returning habit is arranged in the direction of the culm of the expelled culm.

As is clear from FIG. 2, the end face of this culm member 6 is formed into an upward U-shape, and at the rotating end of the culm member 6 there is an auxiliary culm member 6 having the same shape as the end face. is attached so that it can slide freely.

In the figure, 7 and 7' are guide plates, and 8 and 8' are front end upright edges.The guide plate 7' and the front end upright edge 8' are each provided with a long guide 9 in the horizontal direction. A tightening screw 10 provided on the guide plate 7 and the front end upright edge 8 is inserted, and the auxiliary culm collecting member 6' is fixed to the culm collecting member 6 so as to be freely removable and removable.

Reference numeral 11 denotes a guide plate for the culm fixed to the shaft rod 4, and the spring 5 is stretched between the guide plate 11 and a mounting plate 12 provided on the guide plate 7 of the culm collecting member 6.

This mounting plate 12 is provided with a plurality of spring connecting holes 13, and by selecting the spring connecting holes 13, the elasticity of the spring 5 is adjusted and the rotation setting weight of the culm collection member 6 is determined.

Further, a control piece 14 is integrally provided on the lower side of the guide plate 11 and has a certain downward angle.It restricts the downward rotation of the culm collecting member 6, and when the spring 5 is removed, the culm collecting member 6
When the culm is free, it is kept facing downward at a certain angle, and in this state the discharged culm is sent to a cylinder-shaped cutter 15 as described later.

The cylinder-shaped cutter 15 has two feed rolls 18 and 19 mounted on parallel shafts in an opening 17 of a case 16 that is open at the top, and a rotary blade 20 and a fixed blade 21 below the feed rolls 18 and 19.
A cutter member consisting of the above is pivotally supported, and a discharge port 22 is provided at the bottom of the case 16 to open laterally.

As shown by the solid line in Fig. 1, the cutting state of the culm is as follows: the auxiliary culm collecting member 6 is fully retracted to make the culm collecting member 6 in the shortest position, and the spring 5 is removed to move the culm collecting member 6 to the control lever. 14-
This is when the discharge culm flow path supported by L is communicated with the case opening 17 of the cutter 15.

In the figure, reference numeral 23 is a neon flag attached to the culm collecting member 6, which allows the operator to know the operation of the culm collecting member 6 by observing the inclination of this flag.

Next, to explain the operation based on the above embodiment, the harvested rice etc. is automatically and continuously adjusted by the threshing device 2 mounted on the combine main body 1, and the culm is transferred to the rear of the combine main body 1 by the conveying mechanism 3. The culm is transported so that the direction of the culm is perpendicular to the direction of movement of the combine harvester.

The transported culms are sequentially accumulated on the culm collecting member 6 with the auxiliary culm collecting member 6' fully pulled out as shown in FIG. It rotates downward around the shaft rod 4 against the elasticity of the spring 5 and releases the discharged culm bundle into the field.

The state of the culm released into the field is such that the culm collection member 6 is positioned downward (
b) If the distance between the tip and the ground when moving is larger than the length of the culm, the culm will be placed in the field as shown in B in Figure 3, and if H is smaller than the length of the culm. In the figure, the upper end of the culm that has fallen onto the field is leaning against the auxiliary culm collecting member 6', and this is affected by the advancing action of the combine main body 1 and the guide plate T'.
The culm is placed in state A with the addition of the sagging action.

Next, to explain the cutting action of the culm, the auxiliary culm collecting member 6' is fully retracted from the culm collecting member 6 as shown by the solid line in FIG. 12
and place the culm collection member 6 on the control piece 14.

The waste culm collected on the culm collecting member 6 in such a state continuously slides and falls on the culm collecting member 6, is drawn into the case 16 from the tip by the rolls 18 and 19, and is connected to the rotary blade 20. It is shredded by the cutting action of the fixed blade 21 and is continuously discharged from the discharge port 22 of the case 16 to the side of the combine main body 1, and is placed in the field in the form of a ridge as shown in FIG. 3C.

As described above, according to the present invention, the culm can be ejected toward the culm with a simple structure, and the culm can be released in the direction of the culm.

It has the advantage that the culm can be left in an orderly manner in the state shown in B, and the cutting frame can be left in a hostile position when cutting the culm.

In particular, in this invention, the exhaust culm is connected to the cylinder-shaped cutter through the culm collecting member, so the cutter mechanism is simpler than before, making it possible to mass-produce at a low cost, and also making it possible to downsize the combine harvester itself. , has great practical effects.
