Description

[Detailed description of the invention] (a) Industrial application field This invention provides a reaping conveyance unit configured to convey and process grain culms harvested by a reciprocating reaping device along the longitudinal direction of the device. This invention relates to an improvement of a reciprocating type reaping device.

(b) Conventional technology In harvesting machines such as binder, converging type reapers, or combine harvesters, a reciprocating type reaping device is installed horizontally in a direction perpendicular to a grain culm lifting path that is parallel to the direction of movement of the machine. The base of the planted grain culms that are transferred to the above-mentioned grain culm lifting and delivery route is cut by a reciprocating type reaping device, and the harvested grain culms are conveyed along the longitudinal direction of the device to the end of the conveyance. It is common to configure the reaping conveyance section so as to connect it to a binding machine or convergence machine or other conveyance mechanism installed in succession, and this is known, for example, from Japanese Utility Model Application Publication No. 51-60416. However, in the conventionally known reaping device, the height of the upward protrusion of the cutting blade holder (knife clip) from the upper surface of the cutting blade in the reciprocating type reaping device is the same at any position in the longitudinal direction of the reaping device, which is relatively small. It is configured to have a high degree of prominence.

(c) Problems to be solved by the invention Therefore, in the conventionally known reaping and conveying unit, the stump head of the reaped grain culm, which is fed horizontally while the stump cutting section slides on the top surface of the reaping device, is The cutting blade presser, which protrudes high from the upper surface of the blade, encounters resistance as it slides against it, and the sliding resistance increases as it approaches the end of conveyance, where the bulk of the stock head increases as it is transported. This hinders the smooth movement of the grains, leading to problems such as poor stock alignment and disordered posture of the grain culm as a whole, making it difficult to introduce it into the next step, such as a tying machine.

(d) Means for solving the problem Therefore, in the present invention, in a reaping and conveying section configured to transport grain culms harvested by a reciprocating reaping device laterally along the reaping device, the reaping device is The above-mentioned problem was solved by configuring the cutting blade holder so that the height of its upward protrusion decreases as it approaches the end of the lateral feed.

(e) Effect According to the present invention having the above configuration, even though the volume of the base of the stock increases as it is conveyed and collected by cross-feeding, and the sliding resistance with the top surface of the reaping device increases. As the bulk of the stock base increases, the height of the cutting blade presser's upward protrusion is reduced, so the transfer resistance during grain culm transportation does not become extremely large, and the grain culms are kept at a uniform stock base. It is maintained in a good condition and transported smoothly, and is fed in a good posture to a processing mechanism (such as a binding machine) for the next process.

(f) Examples Examples of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is an overall plan view of a reciprocating type reaping device according to the present invention, and FIGS. 2 to 4 are cross-sectional views showing differences in the protruding height of a cutting blade presser at various locations in the lateral direction of the reaping device.

A reciprocating type reaping device 1 has a cutting blade 3 superimposed on the upper surface of a receiving blade 2 so as to be able to slide in the horizontal direction, and cutting blade holders 4 and 5 are placed at arbitrary points in the width direction of the cutting blade 3 to prevent the sliding movement. The cutting blade 3 is forced to reciprocate by a drive mechanism (not shown) that is engaged with a knife head 6 connected to an appropriate position of the cutting blade 3, and the cutting blade 3 is forced to reciprocate. When the present invention is incorporated into a tying machine, the right end in FIG. 1 is installed so as to communicate with the pocket of the tying machine, and this point is the same as in the conventional tying machine.

Therefore, the rear end of the cutting blade 3 is bent upward to provide a rising portion 7, but the rising portion on the left side portion 7a of the figure in FIG. In addition, the right side portion 7b in the figure, that is, the rising portion of the portion close to the side where the binding machine is connected is formed so that the upward protrusion height H thereof is the same as the above-mentioned height. It is formed so as to be appropriately lower than the protruding height H of the left-side portion 7a.

The portion of the cutting blade where the protruding height H of the rising portion is the normal height is supported elastically on the upper surface of the receiving blade 2 by the cutting blade holder 4, but when installing this cutting blade holder 4, the protruding height A regulating tool 8 having a sliding guide portion into which the rising portion 7a of the blade H is inserted is stacked on the inside, and the regulating tool and the base of the cutting blade holder 4 are fixed to the receiving blade 2 with bolt nuts 9, 9. The height of the upward protrusion of the cutting blade holder 4 is the dimension X.

Further, the cutting blade at the portion 7b where the protruding height h of the rising portion is low is supported with pressure on the receiving blade side by a cutting blade holder 5 different from the above-mentioned cutting blade holder 4.

In other words, the above-mentioned point is that the regulating tool 10 equipped with a sliding guide part into which the rising part 7b is inserted is placed on the cutting blade holder 5 with the inside thereof, and both are attached and fixed to the receiving blade 2 with the bolt nuts 9, 9. However, since the protruding height of the rising portion 7b is H>h, the upward protruding height Y of the cutting blade presser 5 is X>Y, and furthermore, the protruding height In the portion 5a that is closer to the right side in the figure than the portion formed in the shape Y, the protrusion height Z of the cutting blade holder is
It has a structure in which the protrusion height Y is lowered even further.

FIG. 5 shows a case in which the above-mentioned reciprocating type reaping device is incorporated into a binder, in which a Notterbill type binding device 12 is attached to the right end of the reaping frame 11, and the reaping device protrudes forward. Between the frames and between the reaping frame and the tying machine, two grain culm lifting paths 13 and 14 facing in the direction of movement of the machine are constructed, and at the ends of these paths,
The above-mentioned reciprocating type reaping device 1 is installed horizontally in a direction intersecting the carrying route, and the right end thereof is connected to the binding device 12.
The pocket portion 15 of the device is communicated with the pocket portion 15 of

The grain culm stock origin derivatives 1
6, 17, 18, 19, and 20, 21, 23 and raking tools 24, 25 are provided, and furthermore, a grain culm cross-feeding mechanism 26 is provided oppositely behind them, and the harvested grain culms are tied by a binding machine. It is constructed so that it can be carried toward the pocket of the person.

Therefore, in the binder having such a configuration, since the protruding height of the cutting blade presser in the reciprocating reaping device satisfies X>Y>Z, the protruding height increases as it approaches the pocket portion 15 of the binding machine 12 Since the height is lower, the sliding resistance of the end of the crop increases even though the volume of the base of the grain culm increases as it is placed on the upper surface of the reaping device 1 and is fed laterally and closer to the binding machine. By gradually decreasing the height of the blade holder, a significant increase in the blade holder can be avoided, and the blade can be sent to the bundling pocket without deteriorating its posture.

(g) Effects of the invention As explained above, the present invention has a reaping mechanism that uses a cutting blade presser of a reciprocating type reaping device in a reaping conveyance section configured to transport grain culms harvested by a reciprocating reaping device laterally along the device. Since the height of the upward protrusion gradually decreases toward the end of the cross-feeding path, it is possible to minimize the degree of resistance imparted to the grain culm, which increases the transfer resistance as the cross-feed progresses. The grain culms can be fed to the next process with good posture and stock origin.
