2. Description of the Related Art Conventionally, a combine that can increase the amount of uncut cereals per stroke by connecting a pre-processing unit that can shave 7 pieces of uncut cereal in front of the traveling machine body is known. (For example, refer to Patent Document 1).
JP-A-10-262437 (page 2-4, FIG. 3, FIG. 6)

  And the pre-processing part (patent document 1, a reaping device in patent document 1) inherits the culm from the stock former scoring device for two strips from the right with respect to the advancing direction of the traveling machine body. Transfer the right main stock transporter to the feed transport section to the threshing feed chain on the rear and the right main stock from the stock scraping device for two strips from the left in the forward direction of the traveling machine. In addition to providing the left main stock transporter that joins the stock transport, the right main from the stock 2 scoring device for the right 2 and the left one of the stock stock Two subsidiary stock transporters are provided that merge sequentially into the stock transporter.

  However, as described above, in the configuration in which two subsidiary stock formers are joined to the main stock former carrier on the left and right sides (right side) from the stock former scoring device for the three strips on the central side, these two subsidiary stocks are used. Sufficient space before and after the original transport body and its transport path is required, which inevitably increases the overall length of the pretreatment unit, leading to an increase in weight and cost. Visibility also deteriorates. In addition, the convergence balance of the cereals tends to be biased at the merging portion of the left and right main stock transporters, which may make it difficult for the stocks of the cereals to be aligned and the handling depth adjustment to become unstable.

An object of the present invention is to solve the above-mentioned problems, and is a weed body arranged side by side in the left-right direction of the traveling machine body, an elevating device for eliciting cereals weeded by the weed body, and the elicitor In a combine that connects a cutting device provided at the rear of the device and a pre-treatment part of seven-row cutting comprising a stock-source scoring device that stirs the stock of cereals into the front of the traveling body, two stocks on both the left and right sides From the left and right main stock transporters that inherit the cereal rice cake from the original scraping device and transport it to the merging section at the rear, and from the stock scraping device for the two strips on one side and the remaining one on the central strip Each inheriting grain cereal and providing two sub-stock transporters that join each of the left and right main stock transporters, and the vertical transmission cylinder that supports the pretreatment section, the forward direction of the traveling machine body As a reference, it is arranged at the boundary position between the fourth cut and the fifth cut from the right end of the pretreatment section. In both cases, the vertical transmission cylinder is provided on the left side between the left and right crawler travel devices in plan view, and the left side portion of the pretreatment portion protrudes outward from the left end of the left crawler travel device by approximately one cutting width. The first feature is that the right side portion of the right crawler traveling device is arranged so as to protrude outward from the right side of the aircraft .
The second feature is that each star wheel of the stock-based scraping device corresponding to the five cutting portions counted from the right in the forward direction of the traveling machine is meshed and transmitted.

According to invention of Claim 1, in the combine which connected the pre-processing part of 7 row cutting to the front of a traveling machine body, it inherits each grain cocoon from two stocks of the left and right both sides, and serves as a back merge part. The left and right main stock transporters and the left and right main stock transporters of the left and right main stock transporters are inherited from the stock stock scoring device for 2 sections on one side and the remaining 1 section of the 3 sections on the central side. By providing two sub-stock source carriers that merge separately to any one, it becomes possible to succinctly configure the two sub-stock source carriers and their transport paths on the left and right sides, with a little front and back space, The problem that the total length becomes longer and leads to an increase in weight and cost as in the case of the conventional pretreatment unit is eliminated, and the visibility of the tip of the pretreatment unit (herbaceous body) from the control unit is not adversely affected. . In addition, it is possible to improve the unevenness of the convergence balance of the cereals at the junction of the left and right main stock transporters, thereby making it easier to align the stocks of cereals and stabilizing the handling depth. In addition, a vertical transmission cylinder that supports the pretreatment unit is disposed at a boundary position between the fourth cutting portion and the fifth cutting portion from the right end of the preprocessing portion with reference to the advancing direction of the traveling machine body. The cylinder is provided on the left side between the left and right crawler travel devices in plan view, and the pre-processing part is arranged in a state where the left side portion protrudes outward from the left end of the left crawler travel device by approximately one cutting width. On the other hand, the right part of the right crawler travel device is arranged so as to protrude outward from the right side of the right crawler travel device, so that the stepping allowance for one line is provided between the left crawler and the uncut ground on the field. Is formed, and a tread is formed between the right crawler and the uncut area of the field.
And according to invention of Claim 2, by meshing and transmitting each star wheel of the stock former scoring device corresponding to the cutting part for five strips counted from the right with respect to the advancing direction of the traveling machine body, The entire width of the pretreatment unit can be made as narrow as possible, so that the pretreatment unit can be mounted without protruding from the loading platform of a transport vehicle such as a truck.
