Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an agricultural mowing apparatus for cutting a grain stalk or the like by reciprocatingly driving a cutting blade superimposed on a receiving blade.

[0002]

2. Description of the Related Art Conventionally, in this kind of agricultural reaper, a cutting blade and a receiving blade are fixed in such a manner that blades individually formed for one pitch are arranged side by side on a support member. It is well known.

[0003]

In the conventional type of mowing apparatus in which individual blades for one pitch are arranged side by side on the left and right, the structure is complicated and the number of parts is large. The assembling is troublesome, and the number of manufacturing steps is increased, resulting in a problem that the manufacturing cost is increased.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an agricultural mowing apparatus which can be constructed at a low cost and which can quickly remove foreign substances on a cutting blade and a receiving blade. .

[0005]

According to a first aspect of the present invention, there is provided an agricultural reaping device, wherein a plurality of receiving blades and cutting blades each having a plurality of blades arranged in parallel on the left and right are integrally press-formed, and the receiving blades are integrally formed. The cutting blade superimposed on the blade is configured to reciprocate right and left, and at least one of the receiving surfaces of the receiving blade and the cutting blade in sliding contact with each other, a shallow groove is formed over the cutting width to remove foreign matter. A long slot is formed in the receiving blade at predetermined intervals on the left and right sides.

(Operation) According to the first aspect of the present invention, since both the cutting blade and the receiving blade are integrally pressed in a state where a plurality of blades are arranged in parallel on the left and right, a single blade is used. Is less time-consuming to assemble than when a plurality of are assembled and assembled. Furthermore, the shallow groove formed in at least one of the receiving blade and the cutting blade serves as a space for foreign substances such as cut straw and mud to escape, and the foreign substance is trapped between the sliding surfaces of the receiving blade and the cutting blade. Is suppressed, and the foreign matter in the shallow groove can be discharged downward through a long hole formed on the receiving blade side so that the foreign matter in the shallow groove can be quickly removed.

(Effects) Therefore, according to the structure of the first aspect of the present invention, manufacturing and assembling of the cutting blade and the receiving blade become simple, quick and inexpensive, and foreign matter is located between the cutting blade and the receiving blade. There is an advantage that the problem that the sharpness is reduced by sandwiching can be solved and the occurrence of abnormal sound can be suppressed.

(Structure) According to a second aspect of the present invention, in the agricultural reaper according to the first aspect, the long hole is set to be longer in the front-rear direction than the front-rear width of the shallow groove. Is a characteristic configuration.

(Operation) According to the structure of the second aspect of the present invention, since the long holes for removing foreign matter are set to be long before and after exceeding the front and rear width of the shallow groove, the foreign matter which has entered the shallow groove is provided. Is in a state of overlapping with the long hole in the entire range of the front and rear widths of the shallow groove, so that foreign substances can be dropped down from the long hole with high certainty and eliminated.

(Effects) Therefore, according to the configuration of the second aspect of the present invention, it is possible to more reliably suppress the occurrence of troubles due to foreign matter in the reaper.

(Structure) According to a third aspect of the present invention, in the agricultural reaping device according to the first or second aspect, the front end of the long hole is located forward of a blade bottom position of the cutting blade. Is a characteristic configuration.

(Operation) According to the third aspect of the present invention, since the front end of the long hole is configured to be located on the front side of the blade bottom position of the cutting blade, it is entangled with the cutting blade. Foreign matter easily collects on the blade bottom of the cutting blade, but the foreign matter on the blade bottom easily falls to the ground side below through the front portion of the long hole.

(Effects) Therefore, according to the configuration of the third aspect of the present invention, it is possible to more reliably suppress the occurrence of troubles due to foreign matter in the reaper.

[0014]

Embodiments of the present invention will be described below with reference to the drawings. Fig. 1 shows the binding and binding machine (binder)
Is shown. This mowing tying machine is configured to be self-propelled by tire wheels 1, and has an engine E that transmits power to the tire wheels 1 via a transmission case 2 and a transmission case 4, a handle 3 for operating a body, and the like. At the front of the mobile unit, a cutting and binding unit A that cuts planted grain culms such as rice and wheat and binds the harvested grain culm is connected, and rotational power is transmitted from the self-propelled unit to the cutting and binding unit A. It is configured to be.

FIGS. 2 to 5 show a clipper-type cutting device 5 provided in the cutting and binding work section A. FIG. The reaper 5 is mounted on the reaping section frame 8 with the cutting blade 6 and the receiving blade 7 stacked one on top of the other, and engages with a crank arm 9 driven by power transmission from the machine body side to engage the cutting blade. 6
The knife head 10 for reciprocatingly driving the cutting blade 6 is integrally connected to the cutting blade 6.

As shown in FIG. 5, the cutting blade 6 and the receiving blade 7 are integrally formed by press molding in a state in which a plurality of blade bodies 6a and 7a are provided side by side on the left and right. And
The cutting blade 1 is a knife clip 1 provided on the left and right at predetermined intervals.
The bolt 1 is connected to the receiving blade 7 so as to be reciprocally slidable by 1 and a horizontally long slat 12. A knife bar 13 that slides on the cutting blade 6 in the reciprocating range with the night clip 11 and the slat 12 in a reciprocating range, and a protection member 14 that protects the knife head 10 and the like from being entangled with grain stems or the like are bolt-connected.

Further, the receiving blade 7 is formed with a shallow shallow groove 15 extending in the left-right direction over the entire width in the left-right direction on the upper surface forming the sliding surface of the substrate portion 7b provided with the blade body 7a. The shallow groove 15 is formed relatively wide in the front-rear direction. In the receiving blade 7, perforated holes 16 are formed at predetermined intervals on the left and right as long holes penetrating up and down and formed to be longer and shorter than the front and rear width of the shallow groove 15. In addition, the front end of the perforated hole 16 is
It is formed so as to be located on the front side of A. Also, a plurality of small holes 17 are formed in the cutting blade 6 side so as to penetrate vertically. These small holes 17 can be used as lubrication ports for the sliding contact surface between the receiving blade 7 and the cutting blade 6.

Another Embodiment In the above embodiment, the shallow groove is provided only on the receiving blade side. However, the shallow groove may be provided only on the cutting blade side. It may be provided on both sides.
