The present invention is a Varican-type mowing device for use in various agricultural machines such as mowing machines and combines. Specifically, the two moving blades are polymerized by polymerizing two moving blades on fixed blades arranged in the lateral direction of the gas. An agricultural Varican mowing device configured to reciprocate in opposite directions along a stationary blade.

Conventionally, a mowing device that polymerizes one movable blade to a fixed blade and reciprocates the single movable blade along the fixed blade has been widely used.

However, in this structure, the vibration and noise when driving the movable blade are large and there is room for improvement.

This led to the appearance of a structure that reciprocated in the opposite directions with two movable blades.

According to this structure, since the two movable blades reciprocate in directions opposite to each other, the vibrations are canceled with each other and noise is also reduced.

However, as shown in FIG. 5, a new problem arises in that a dead space S of approximately triangular shape occurs and the planted span located in the dead space S cannot be cut.

To solve this problem, as shown by the phantom line in FIG. 5, the span segment (D) is provided in front of the dead space (S), and the dead space (S) as the two span segment (D). It was thought to distinguish the planted span from left to right.

However, this structure requires a span segment (D) separate from the fixed blade (1), and the structure is complicated because the span segment (D) must be fixed in front of the dead space (S) in some way. It becomes.

In addition, the installation of a too large span segment (D) may cause the span segment (D) to collide with ridges or foreign matter at the crop planting area, and when the span is guided, There was a concern that the degree of cutting will become large enough that the cutting height will be significantly higher than the cutting height of other spans.

The present invention has been completed in the light of the present state, and it is possible to reliably classify the planted span to enter the dead space as described above as a simple structure to the extent possible, and also to avoid the possibility of bumping up the raised part of the crop cultivation site. It also aims to provide a mowing device whose cutting height is not too high.

In order to achieve this object, the mowing device according to the present invention is thinner toward the front by looking at one of the unit of the fixed blade positioned between the two movable blades in a state in which the two movable blades are adjacent to each other and the other of the fixed blade. In addition to the unit projecting toward the front of the body rather than the unit body, both edges of the unit of the fixed blade projecting toward the front of the body is formed in a gentle slope of the proximal end with respect to the traveling direction of the body, and the front end in a steep slope. It is characterized by doing.

In this way, one of the unit of the fixed blade becomes thinner toward the front and protrudes toward the front of the gas than the other unit of the fixed blade, so it is a simple structure with a simple structure even if the special span separator is not actually installed.

Since both edges of the unit are steep inclined toward the proximal end, the front end of the unit is steep incline, so that it is possible to reliably cut the span planted as the proximal end of the gentle oblique. The amount can be made relatively small.

Therefore, it is less likely to encounter the ridge of the crop cultivation site of this unit, and the extent of collapse when the span is guided is not large.

As described above, it is possible to obtain an agricultural Varican harvesting device that can be surely divided in a simple structure and has a low concern of contact with the ridge of the crop growing place and the cutting height is not too high.

EXAMPLE

As shown in FIG. 1, a plurality of span section attachment pipe portions 2 having one fixed blade 1 arranged side by side in the side of the cutting frame. And a plurality of knife clips (5) to slide the two movable blades (3) and (4) arranged side by side in the direction of the body, respectively. _Two polymerized to the fixed blade (1) described above in the state of being prevented by disassembly, and attached to the transmission case part 6 of the harvesting frame frame so as to be rotationally driven around the shaft center P ₁ or P ₂ . One of the crank arms (7) (8) to the knife head (9), which is attached to one movable blade (3), the other crank arm (8) to the other movable blade (4) The two movable blades 3 and 4 are driven in a state of reciprocating sliding on the fixed blade 1 in the opposite directions by being engaged with the knife head 10 attached thereto. To form a Varican harvesting device for combines.

Each of the two movable blades 3 and 4 described above comprises a plurality of movable blade component units 3a arranged side by side in the gas lateral direction. And (3b) or (4a)... And one knife bar 11 or 12 which connects (4b) and the units 3a and 3b for moving blade construction thereof, or (4a) and (4b) as shown in FIG. Since the composition.

And in the two movable blades 3 and 4, a plurality of the above described movable blade structural units 3a... (3b) or (4a)... Among the movable blades 3 or 4, the inner edge of the movable blade constituting unit 3b or 4b of the movable blade 3 or 4 is replaced with another movable blade constituent unit 3a or 4a. In the same manner as in Fig. 2), the left and right edges 13 or 14 are formed to be inclined with respect to the gas back and forth direction (see Fig. 3).

The fixed blade 1 includes a plurality of fixed blade constituent units 1a ... arranged side by side in the gas side direction. And (1b) as a storage stand 15 which connects as shown in FIG.

And a plurality of the above-described fixed blade unit 1a. And (1b), the central unit (1b) located in the center of the fixed blade (1) in the gas side direction is tapered toward the front as shown in FIGS. 1 and 3, and the other fixed blade (1b). It is made as one plate of a larger shape in terms of side width and length than the structural unit 1a, and the front end protrudes toward the front of the body than the other fixed blade structural unit 1a, or the two above most close states. Each of the movable blades 3 and 4 is configured such that the proximal end abuts against each of the above-described inner end movable blade structural units 3b or 4b.

In other words, the center span between the inner edge movable blade constituting unit 3b of one movable blade 3 and the inner edge movable blade constituting unit 4b of the other movable blade 4 is the center described above. Due to the shape tapered toward the front of the unit 1b, the span is guided to the proximal end of the central unit 1b so that the unit for moving the inner edge of the central unit 1b is opposed to the proximal end of the central unit 1b. 3b) or (4b) is cut | disconnected.

In addition, as shown in FIG. 3, both edges of the central unit 1b described above are moved to the proximal end with respect to the traveling direction of the gas, and the movable unit structural units 3a, 3b, or 4a. The front end is inclined so as to be a large angle β at a small angle α approximately coincident with each of ... (4b).

In other words, the proximal end of the central unit body 1b is constituted by a gentle slope, and the front end is constituted by a steep slope.

Therefore, as described in the above, it is possible to reliably distinguish the span as one central unit 1b without requiring a special span segment, and to contact the ridge of the crop cultivation site can be avoided as much as possible.

In addition, the central unit (1b) has a ground level of the front end portion protruding forward than the other fixed blade unit (1a) in spite of the posture descending to the mowing device as shown in Figure 4 As seen from the side of the body so as to be high, the front end is bent so that the front end rises with respect to the base end side.

By this structure, the contact with the raised part of the crop cultivation site can be further avoided.

Alternatively, as shown in Fig. 3, the width W 'of the front end of the proximal end of the central unit 1b is made smaller than the width W2 between the other end of the unit.

Therefore, the central unit (1b) consisting of one plate can be a relatively small one and there is an effect that can be avoided in contact with the cultivation site uplift even in this advantage.

19, which is shown in FIG. 4, is the drive shaft of the front processor, and 20 is driven to drive the rotating body (not shown) which scrapes the triangular span into the mowing device and also sends the mowed span back. (21) is a transmission shaft to the lifting device (not shown).

In the above embodiment, the two moving blades 3 and 4 have substantially the same length, and the central unit 1b positioned in the center of the fixed blade 1 is moved toward the front of the body than the other unit 1a ... Although the protrusions are shown, the movable blades 3 and 4 do not necessarily have to be the same length.

For example, in the state where both movable blades 3 and 4 are close to each other, one of the units of the fixed blade 1 located between the movable blades 3 and 4 may be protruded toward the front of the body. have.

In addition to combines, mowing can also be applied to mowing equipment for various agricultural machinery such as the Royal Culver Harvester.
