Description

[Detailed Description of the Invention] As a harvesting machine that reaps punto corn, grass, etc., cuts it into necessary lengths, and stores the bellows in a trailer, etc., there are 1, for example, the Japanese Unexamined Japanese Patent Publication No. 54-4261'7 and the Japanese Unexamined Patent Publication No. 56-3. '9 '71
Books in positive and negative formats such as 1st class are well known. These harvesters are attached to the tractor in such a way that the reaping and cutting part can protrude towards the right side of the tractor. This type of harvester is generally used for reasons such as the cutting part after harvesting is located on the right side of the tractor, making it easy for the operator to see the cutting situation and work easily. Things that are established 7-, t, ru. However, for example, in a field where Punto corn is raised, harvesting work is carried out using a known harvesting machine.

At the beginning of the cutting, the tractor TK harvester H is attached to the side as shown in Figure 1, so when entering this harvesting field, the tractor T is used to carefully trample the crop Z8. By crushing and tx ri, therefore, when the harvester enters the field, the crop can be raised by the width of the machine 2.
It is customary to cut and remove the leaves by two people to create a path where the tractor can run and turn freely without interfering with the harvesting work, but the large area fR + 1 t! Therefore, manually cutting and removing the crops in the tractor path requires a great deal of labor. Also, as mentioned above [-
A harvester H is attached to the rear three-point link TB of the tractor T, and the harvester H is installed on the rear three-point link TB of the tractor T.
A type of tractor (σ) in which mowing work is performed by running backwards is well known in foreign countries, but this is a mountain-spec tractor T that mainly runs forward and has rear wheels as well as front wheels so that it can freely run backwards. Since this is a specially modified specification (sigma) tractor equipped with a steering system, the structure of the tractor itself is complicated and, in addition, expensive.

This places a heavy economic burden on the user.

The great invention is to provide a new harvesting machine in view of the above-mentioned circumstances, and one embodiment thereof will be explained in detail below with reference to the drawings.

T is a tractor, and H is a harvester (in the tree embodiment, it is a harvester for long culm crops such as punto corn). The configuration of H is as follows: 1. The front end is a long culm cutting feeding section with a cutting blade. The width center section is roughly composed of a cutting blower part 2 on which the shilling-shaped rotary blade and blower blades are attached, a blower duct 3 communicating with the cutting blower part 2 and standing upright on the child side, and a frame FK. A folding frame 4 is fixed and horizontally installed at the lower rear end portion of the cutting blower 2, and a connecting tool 5 is provided at the left end of the folding frame 4. and.

1. Pivotally attached from this connector 5 by a support shaft 6. A horizontal frame 7 is connected to the horizontal frame 5 so as to rotate 180 degrees in a horizontal plane. When the posture of the horizontal frame 7 is in the position where it projects to the left side of the housing @1GH, the folding frame 4 and the horizontal frame 7 are fixedly supported by the support shaft 6 and the fixed bin 8.

In this position, as shown in FIG. 3, the harvesting machine H is attached to the side of the tractor T and the machine moves forward to reap and harvest the crops. A transmission M for inputting the rotational power of the tractor T is installed approximately at the center of the horizontal frame 7, and a top mast and a pair of lower link brackets 9 on the left and right sides are installed at the same site.
The end W opposite to the support shaft 6 is fixed to a connecting piece 10 having a through hole IQA, and this is fixed to the end W opposite to the connecting tool 5 of the front folding frame 4.
゛ through hole? It is designed to match OA. On the left side of the cutting blow-up W2, a mission MAI-folding Tatami 7-ray A4Vc that operates the cylinder-shaped rotary blade or the reaping feed section 1 is fixedly installed. In the front row part of the mission MA, the input shaft 11k by spline Narusugi r is installed horizontally protruding toward the tractor, and the
Input shaft 11 with spline 5'2 in rear row part
The input shaft 11A is installed horizontally protruding toward B or anti-tractor F.
, 11B have a built-in gear train in the mission MA so as to rotate in the a and inward directions (in opposite directions), respectively.

The shaft 12 coaxially connected to the input shaft 11A rotates the cylindrical rotary blade, and the pulley 13 provided with the mission MAff operates the reaping feeding section 1.

In addition, for the input shaft 11A or input shaft 11BVr of the mission MA from the mission M, there is a flexible transmission shaft J' that is extendable and retractable.
fy are connected in a detachable manner. 14 is a trailer 16 (for storing and transporting harvested products) fixed to the approximate center of the horizontal frame 7
A hitch for connecting 8 rows, 15 indicates a support wheel for harvesting mode H. The TR is a truck (for storing and transporting harvested products) that travels behind the tractor and the harvester to reap the harvest by moving backwards during the splitting process.

Next, explain the function of the main unit.For example, when starting to cut from one crop with 1ill H□, which allows punto corn to stand up, the tuna that is connected to the tractor T and the harvester H is the second. The position shown in the figure is converted to the position shown in Figure 4.

That is, insert the connector 5ff, cut off the pin 8 by 4Jv, and remove the input shaft 11 and the universal transmission shaft J into which the AVC is inserted.
! Since I is solved, next Harvest 4: it + H is the spindle 6
Turn the folding frame 4 by 180 degrees by rotating it in one direction around
After overlapping the connecting pieces 10° and aligning the respective through holes 108, the connecting bottle 8 is inserted.

The folding position can be fixed. Father, the universal transmission shaft J that connects the mission Mff is the input shaft 11Bf of the mission MA.
f Insert and connect. From ff, the second illustration θ)
+ff) The center of gravity of the tractor T and the center of the harvester H are approximately on the same line, and the reaping feeding section 1 of the harvester H is oriented in a direction opposite to the forward direction of the tractor T. As for the procedure for turning the folding frame 4 in one direction W, refer to Figure 8IP'4 and pull the fixed bin 8 without turning it. Then, when the noddle of the tractor T is turned rc to the left (arrow A) and moved forward, the horizontal frame 7 and the folding frame 4 form a substantially V-shaped planar shape with the support shaft 6 as the center. Then, when the handle of the tractor is turned to the right (arrow B) and moved backward, the folding frame 4 will be folded th with respect to the two-row frame 7M. From Kowani, the tractor T is driven backwards into a field where one crop is standing, and the -1 inch crop of the backward travel (arrow B') is harvested. Create paths within the field that allow for free movement and turning. After this path has been created, the harvester H is placed in the commonly practiced side-mounted position as shown in Figure 3, and the tractor is driven forward (arrow F'l) to harvest the crops. The same period is harvested. That is, the connected pieces IQ, IQ"K
The connecting bin 8 to be inserted is rounded, and the input shaft ii, the universal transmission shaft J into which the aK is inserted is rounded, and then the housing H1 machine H is rotated 180 degrees in the direction 1f about the shaft 6, and the base of the horizontal frame 70 is 58 and the connecting tool 5 of the folding frame 4 are overlapped, and the respective σ) traces L and hole 5H are aligned to connect the rear connecting bin 8.
Insert and fix the harvester H in a working position protruding to the right side of the tractor, and connect the transmission shaft J&' to the mission MVr. , the hook is inserted and connected to the input shaft 118 of the mission MA. To briefly describe the power transmission of the first cropping cloth, as shown in Figure 2, when a tractor is mowing a path (splitting work), the power of the tractor T is P.
It is transmitted from the TO axis to the universal transmission shaft J, passes through the mission M, and then via the universal transmission shaft J.
Then, the gear train in the mission MA rotates the shaft 118 in the direction A.

The shaft 12 coaxially connects the cylindrical rotary blade to the pulley 1.
Reference numeral 3 denotes a shaft that rotates the reaping feeding section 1, respectively. Furthermore, as shown in FIG. 4, in the case of normal work in which the tractor moves forward with the harvested camellia H protruding to the right, power is transmitted from the PTO shaft of the tractor T to the shaft via the swivel shaft J. 118 is rotated in the A direction r, and it is the same as above. The blow-up duct 3 is operated by an electric actuator, etc.
It can turn left and right freely, and the trailer 6 is connected to the hitch 14, and the trailer 6 is towed at the same time by a tractor, and the blown-up crops can be stored in the trailer 6Vr using the 3 blow-up ducts.

Effects of the invention with the above configuration! ) L, as mentioned at the beginning, that is, (A) The reaping and cutting part can be folded 180 degrees in a horizontal plane, and the folding operation can be done by changing the insertion and removal of the connecting bin that is inserted into the frame connecting part. It is a simple operation to hook the transmission input shaft to the transmission input shaft, and the folded position allows the tractor to freely run and turn at the beginning of mowing in a field where two crops are standing. Even in the case of creating a passageway for the user W to carry, the work can be done by attaching it to the rear of a commonly used regular specification tractor and traveling backwards, so it is convenient for the user W to do the work of cutting in the middle. (Equipped with front and rear wheels and configured so that both forward and backward cropping can be performed freely) is not required, no extra machinery investment is required, and the economic burden is reduced h7>6 (B) Also, reaping When the cutting section is in a folded position, it is possible to carry out the harvesting process by attaching it to a specially modified tractor and driving backwards. Also, since there is no lateral protrusion of the cutting section, it is convenient to drive on the road.
In addition, even if the harvesting machine is stored in a warehouse, the volume of the machine body is compact, so it does not take up much space. In addition, when the two products are loaded on a truck or the like and shipped, handling becomes easier and transportation costs are reduced.

(After C1 split crop shield, it is easy to reverse the reaping cutting part in the normal direction and projecting the reaping cutting part to the right lateral part of the tractor.) Depending on the posture, the normal tractor can move forward. The reaping work can be carried out for inspection, and the frame A [
A trailer is pulled onto the fixed pitch and the feed from the blow-up duct is sequentially stored in the trailer.
