Description

[Detailed Description of the Invention] The present invention is a conveyance guide device in a binding section of a combine harvester or the like.

In other words, a tying machine is installed across the top and bottom of the deck that supports and guides the straw, and the packer rotates in a constant trajectory from below to the top and bottom of the waist deck, which connects the upper nodule cover and the top surface of the lower deck. At the bundling section of a combine harvester, etc., which is configured to feed straw from the front and bundle it, the packer picks up the straw on the deck and sends it to the bundling side, ensuring good separation from the following straw. The object of the present invention is to provide a simple structure that can be arranged, bundled, and released without disturbance, and can be suitably implemented.

Next, the embodiment shown in the drawings will be described.

Fig. 1 shows a side view of the combine harvester, in which a reaping section C is installed at the front of the machine body supported by crawlers 6, and a cover section is installed at the rear of the threshing section B installed behind the reaping section C. The straw culm 8 sent out from the foot chain 7 of the threshing section B is extended diagonally above the cover part.
It is installed so that it can be transported backwards, and has the same structure as the conventional type.

Behind the cover part, a deck 1 is provided which supports and guides the straw culm 8 sent out by the straw exhaust check 79. Binding machines A extending over the top and bottom are installed, a culm base alignment plate 11 is erected on the side, and a shutter 12 is installed in the vicinity thereof so as to be able to rise and fall freely, and these are covered with a cover 13.

The bundling machine A is equipped with a bundling case a that extends in the vertical direction of the deck 1 on the side and transmits power to and supports each part, and a straw culm 8 is installed between the knot cover 3 and the deck 1 that are above the top surface of the deck 1. A knot part 15 is installed above the knot cover 3, and a release arm 16 that rotates in a fixed trajectory is installed above the knot cover 3. .16' is installed, deck 1
A needle 17 that rotates toward the nodule 15 is installed below, and a packer 2 is installed on the side of the needle 17, and the packer 2 protrudes from the point opening onto the deck 1 to cover the nodule. It is installed in such a way that it passes through the front point of No. 3, goes around once, sinks below the deck 1, and rotates again toward the entrance on a constant trajectory A, and is constructed in the same manner as before.

In front of the nodule cover 3, guide rods 4 for guiding the straw culm 8 downwardly in the nodule cover 3 until it is raked by the packer 2 are arranged in series so that the front side is higher when viewed from the side. A spring rod 5 having an upper end 5a connected to the tip end thereof is extended from the packer 2 to the culm base side of the straw culm 8, and is lowered from the front to the rear when viewed from the side. The lower end portion 5b has an extended shape and is directed rearward approximately parallel to the upper surface of the deck 1, and then curved downward to approach the upper surface of the deck 1 to form a recess P, and this recess P can be viewed from the side. As seen, the packer 2 is configured to approximately coincide with the point opening through which it passes over the deck 1, and the lower end 5b side presses the culm side of the straw culm 8 against the deck 1 surface between the point opening and the front point. The spring rod 5 is installed and configured such that the entire spring rod 5 maintains elasticity.

During combine harvester operation, when the straw culm 8 threshed in the threshing section B is carried backwards by the straw removal chenograph 9, the packer 2, which rotates in a constant trajectory A, carries out the straw culm 8 sent onto the deck 1. The needle 17 is inserted between the top surface of the deck and the nodule cover 3, supported by the door 14 and the shutter 12, and while aligning the culm side with the culm alignment plate 11, the needle 17 is inserted until a certain pressure is applied to the door 14. The arm 16.16 operates, wraps around the binding cord, ties it up, and releases the binding part.
' to release them backwards, and then bundle them one after another and release them.

In that case, the packer 2 moves along the trajectory from the point to the front point C side, pushing up the straw culm 8 and raking it in, and near the culm base, the lower end 5b of the spring rod 5 is moved from above.
The straw culm 8 stagnated in the concave portion P is pressed downward, and the guide rod 4 guides the nodule cover 3 in front of it. The straw culms 8 that had been stagnant in the recess P are raked in, and the following straw culms 8 are stagnated on the deck 1, separated from the straw culms 8 that are raked by the packer 2, and are raked and bundled in an orderly manner.

In this way, the present invention has the bundling machine A installed above and below the deck 1 that supports and guides the straw, and the packer 2 that rotates in a constant trajectory from the bottom to the top of the deck 1 to tie the knots in the upper part. In a bundling section of a combine harvester or the like configured to be able to bundle straw by feeding it from the front between the cover 3 and the upper surface of the lower deck 1, a guide rod is provided in front of the knot cover 3 to guide the straw from above. 4 is extended, and on the side of the position where the packer 2 protrudes above the deck 1 and acts on the straw on the culm side of the straw from the packer 2, there is a spring rod 5 that presses the culm side of the straw from above. The lower end portion 5b extends downward from the front to the rear when viewed from the side, and the lower end portion 5b is curved downward after facing the rear to approach the upper surface of the deck 1 to form a concave portion P. Packer 2 on concave part P
Since the structure is configured such that the point is approximately aligned with the point where the straw passes over the deck 1, when the packer 2 scrapes the straw on the deck 1 toward the lower side of the knot cover 3, the straw is embedded and the packer 2 removes the straw. When the straw is about to be lifted, the lower end 5b of the spring rod 5 presses the culm side of the straw downward, and the straw is temporarily stagnated in the recess P by the raking force of the packer 2. Since the straw is raked in and the following straw is stagnated, the grain base side entangled by the leaf sheaths is separated, and the straw raked by the packer 2 can be reliably separated from the following straw. , the separation and scraping by the packer 2 can be carried out in an orderly manner without any disturbance, and the product can be bundled and discharged, and has the advantage that it can be carried out suitably with a simple structure.
