The culm reel of the general-purpose combine is configured so that it can be moved up and down and moved and adjusted in the front-back direction. The weeding guide is also moved in the same way, and the weeding function is performed smoothly as before while maintaining the front-back relationship between the weeding guide in the front position on the uncut side and the suction reel in the rear position, and scratching. The purpose is to prevent the uncut culm that has fallen to the front side of the included reel from getting entangled with the reel.

The present invention has taken the following technical measures to solve the above problems.

That is, according to the first aspect of the present invention, the scraping reel (4) for scraping the crop culm introduced between the left and right weeding tools (17) toward the rear cutting blade device (5) is moved up and down. In a general-purpose combine that can be moved up and down in the direction and can be moved and adjusted in the front-back direction, the weeding tool (17L) located on the uncut land side is at least squeezed from the front position of the culm reel (4). A weeding guide (19) for separating the stalk culm to be cut and the stalk culm on the uncut side to the left and right is provided near above the rotation shaft portion (18) of the reel, and the weeding guide (19) is described above. It is characterized in that it is configured to be movable in relation to the movement of the scraping reel (4) up and down and back and forth.

According to a second aspect of the present invention, in the first aspect, the weeding guide (19) is pivotally attached to the base end side so as to be swingable in the front-rear direction, and the upper end side is from the bearing portion of the suction reel. It is characterized in that it is connected to the protruding reel arm (20) via an interlocking member (21) in the front-rear direction.

In short, according to the first aspect of the present invention, since the uncut side crop is guided to a position where the weeding guide does not interfere with the scraping action of the scraping reel, the uncut side crop is entangled with the scraping reel. First, continuous work can be performed smoothly. In addition, since the weeding guide moves in relation to the vertical and forward movements of the scraping reel, the scraping reel and the weeding guide operate while maintaining a predetermined relationship position, and the weeding function of the weeding guide is It can be done smoothly as expected.

According to the second aspect of the present invention, in addition to the effect of the first aspect, the weeding guide has a structure in which the base end portion is pivotally attached around the horizontal axis core and swings in the front-rear direction. Even if the built-in reel moves back and forth and up and down, the distance between the front and back of the scraping reel and the weeding guide is kept substantially constant, and the weeding guide always shifts ahead, ensuring and smoothing the weeding action. obtain.

Examples of the present invention will be described with reference to the drawings.

FIG. 1 shows a general-purpose combine that cuts and harvests stalks of crops such as rice and wheat that grow up in the field while running on its own, and is located on the front side of the vehicle body 1 having a pair of left and right running crawlers 2 and 2 at the bottom. Is a scraping reel 4 equipped with a scraping tine 3 that scrapes the stalk culm backward, a cutting blade device 5 that is a varican type cutting blade device that cuts the stalk culm after scraping, and a stalk culm after cutting. Is provided with a pre-harvesting processing unit 8 composed of a scraping auger 7 or the like for scraping the stalks onto the table 6.

The scraping reel 4 is configured to move up and down depending on the type of crop or the length of the crop, and is also configured to be movable and adjustable in the front-rear direction.

In the feeder house 10 equipped from the left side to the rear of the pre-cutting processing unit 8, the feed conveyor 11 that inherits the crop culm from the pre-cutting processing unit, lifts and transports it rearward and upward, and supplies it into the threshing unit 9. Is equipped.

On the right side of the feeder house 10, a driving operation unit including a driver's seat 13 and an operation box 14 is equipped, and behind the operation unit, a grain tank 15 for temporarily storing the harvested material is installed. The grain in the grain tank is discharged to the outside of the machine by the discharge auger.

In the pre-cutting processing unit 8, weeding tools 17 are installed in front of the side frames 16L and 16R located on the left and right ends of the cutting blade of the cutting blade device 5, and as shown in FIGS. 2 and 3, the weeding tool 17 is installed. Of the left and right weeding tools, the weeding tool 17L on the left side, which is on the uncut land side, rises forward and upward at a predetermined distance forward position of the culm reel 4, and at least from the rotating shaft 18 part of the culm reel 4. A weeding guide 19 is provided which extends high to near the upper part and separates the culm to be cut and the culm on the uncut side by pushing them to the left and right. According to this, the crop culm on the uncut side that has fallen on the crop culm side to be cut is directed outward to a position where the scraping action of the scraping reel 4 is not hindered by the action of the weeding guide 19. You will be guided separately.

The weeding guide 19 pivotally attaches the base end side (lower end side) to the weeding tool 17L so as to swing back and forth around the lateral axis Q, and the upper end side of the weeding guide is a scraping reel. It is connected to the reel arm 20 projecting from the bearing portion of the above via an interlocking member 21 in the front-rear direction.

Therefore, even if the culm reel 4 moves up and down and back and forth, the degree of inclination of the weeding guide changes, but the distance between the culm reel and the front and back does not change, and the culm reel 4 swings back and forth while maintaining a predetermined distance. Therefore, it exerts the desired weeding function, and the uncut culm does not fall to the reel side and get entangled.

In particular, when the scraping reel 4 is moved back and forth, there is no possibility that the scraping reel will move to the front side of the weeding guide and cause a problem. The scraping reel has a configuration that can be moved up and down around the fulcrum P and can be expanded and contracted and moved back and forth via the reel rotation transmission device.

As shown in FIG. 3, the weeding guide 19 is offset from the interlocking member 21. That is, as shown in the example of FIG. 3, since the interlocking member 21 is fixed to the reel arm 20 inside the weeding guide 19, there is no catching resistance of the crop flowing outside. Further, since the interlocking member is provided toward the tip of the reel arm, there is an effect that the crop can be guided and guided to the inside of the reel.

Further, as shown in FIG. 4, the interlocking member 21 has a configuration in which the tip of the weeding guide and the intermediate portion of the weeding guide can be selected, so that the amount of forward protrusion of the weeding guide can be changed. Adaptability can be expanded by crops and fields. For example, in the case of intermediate connection, the weeding guide comes out more forward, so it is easier to weed for long crops. Further, in a place where the ridges of the field are surrounded high, workability deteriorates if the weeding guide protrudes too far forward, but it can be improved by switching to the upper connection.

Next, an example of FIG. 5 will be described. On the start end side of the feed conveyor (entrance of the field house), the horizontally long floating drum 23 around which the feed conveyor 11 is wound is swayed up and down with the horizontal axis 24 as a fulcrum. It is erected on the moving arm 25, and is tensioned downward by the tension spring 26, and moves up and down depending on the amount of crops sent.

The swing arm 25 is detachably fixed with an outer member 27 from the outside of the feeder house through an opening, and a stopper 28 is provided on the outside of the feeder house and above the outer member 27 to regulate the upper limit of the floating drum 23. It has a structure. Due to the upper limit regulation of the stopper, the drum does not rise more than necessary, it prevents foreign matter from being caught, and it is possible to reliably convey the drum with an appropriate amount.

If the stopper 28 has a screw type bolt configuration, the vertical width of the drum can be finely adjusted, and in the embodiment, if a cap-shaped elastic body to be inserted into the bolt screw portion is provided as a cushioning material, the stopper 28 is different. There is no noise and it can be carried out inexpensively. The cushioning material of the stopper may be an elastic body integrally molded with bolts.

The following embodiment relates to the combine sun visor 30 (see FIGS. 6 and 7) and has a grain tank 15 protruding above the radiator cover 31 of the driver's seat 13 and a discharge auger extending from the rear to the front. In the general-purpose combine, when the sun visor 30 is provided above the driver's seat 13, the sun visor support base 32 is attached to the upper part of the front end of the grain tank 15. That is, the support base portion 32 has a strong framework structure in which the support plate 33 and the support pipes 34 are raised to the left and right, and the support pipes 34 and 34 are. It is configured to be refracted and fixed rearward via the refracting portion 35 at a position higher than the upper surface of the grain tank, and the support pipe and the sun visor are configured to be foldable.

In short, when the sun visor 30 is stowed, as shown in FIG. 6, the sun visor 30 at a high position above the driver's seat 13 is tilted backward, but after the refracting portion 35 is released, the grain tank is released. It is configured so that it can be folded and stored by tilting it backward to the upper surface position of 15. In this case, it is desirable to store the auger in a position that does not interfere with the operation of the discharge auger. On the contrary, if it is tilted to the front cutting part side and stored, the front view will be obstructed.

In addition, if the angle can be adjusted at the folding position of the sun visor, it becomes easier to respond to solar radiation conditions. The driver may drive while sitting in the seat or while standing, but the sun visor should be in a high position so that he can work while standing, and it may be low when working while sitting. It would be convenient if it could be adjusted up and down arbitrarily.
