Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a culm conveying device from a reaping section to a threshing machine in a direct current combine harvester, which shortens the overall length of the reaping section and always supplies the reaped husk to the threshing machine with the ear leading. This is how it was done.

By the way, in a DC combine harvester, the husks harvested in the cutting section at the front of the machine are collected in the center of the machine by a horizontal auger placed behind the cutting blade, and then fed to the threshing machine by a vertical conveyor. Although it is considered to be a composition,
Conventionally, the auger was configured to wrap the culm below and feed it horizontally on the floorboard, so if the culm was short, it would be rolled into the auger from the tip side; If the size is long, the tip will ride on the top of the auger and get caught under the auger from the stock side, which will cause the culm supplied to the threshing machine to be oriented unevenly, causing defective threshing. It had become. To deal with this, it is possible to make the distance between the cutting blade and the auger longer to ensure that even if the culm is long, the cutting blade will be rolled in from the tip side to the bottom of the auger. Increasing the distance between the auger and the auger increases the overall length of the reaping section, which in turn results in an increase in the size of the machine.

The present invention was made in view of the above circumstances, and has a configuration in which a cross-feeding auger is installed horizontally behind the cutting blade, and a vertical conveyor is placed from the rear of the center of the auger to the handling room of the threshing machine. , the horizontal feeding part gathers the left and right sides of the auger to the center with the stock base side of the reaped husk held upward, and the husk culm gathered in the center part jumps onto the vertical feeding conveyor. By installing an auxiliary auger behind the left and right cross-feeding parts of the auger that holds and cross-feeds the tip side of the cut husk, the husks that have been harvested at the base of the husk with the cutting blade can be removed. In the posture when lodging the culm backwards, that is, in the posture in which the tip of the culm is directed toward the handling room, the receiver is stopped on the cross-feeding part of the auger and the auxiliary auger, and while maintaining that posture, the culm is gathered in the center. The above-mentioned flip-up section allows the receiver to be passed onto the vertical conveyor, thereby ensuring that the grain culms are always fed into the handling room with the ears in front, without increasing the distance between the cutting blade and the auger. Thus, the threshing process for the shell culm can be performed satisfactorily.

This will be explained below with reference to the embodiment shown in the figure. Reference numeral 1 denotes a threshing machine mounted on a traveling device 2. A handling chamber 3 is provided in the front part of the threshing machine, and a handling barrel 4 and a receiving net 5 are arranged. A swing sorting plate 6 is provided from the bottom to the rear of the handling room.
It is a dobetsu section equipped with conveyors 8 and 9 for transporting Toumi 7 and -2 second materials, and a beater 1 for discharging straw is installed at the exit of the handling room.
0, and a straw walker 11 for transferring straw to a discharge section at the rear of the threshing machine is disposed further behind it.

Further, a tank 12 is provided at the top of the threshing machine to store the first thing carried out by the conveyor 8, and a control section 13 is provided on the front side of the threshing machine. Reference numeral 14 denotes a reaping section installed in front of the threshing vs1, and the core section includes a divider 15 for determining the cutting width, a culm pulling reel 16, and a cutting blade 1.
At the same time, a cross-feeding auger 18 is installed horizontally relatively close to the rear of the cutting blade, and a vertical auger 18 is installed from the rear of the center of the auger to the entrance of the handling chamber 3 of the threshing machine 1. A feed conveyor 19 is installed, but □1
'As shown in Fig. 2, the transverse feed ocher 184''!, the left and right side parts 18', 18' are the transverse feed part with the spiral plate 18a wound around the shaft part, and the central part 18'' is the shaft part III around the shaft part III. A jumping section is formed by erecting flat plates 18b in a radial direction.

Here, the torsional direction 9 of the spiral plate 18a of the horizontal feeding section is a direction in which the object to be transferred is transferred toward the side or toward the center with respect to the rotation of the auger in the A direction, and the vertical feeding conveyor 19 is set at the upper side 19a. is configured to run in a direction (direction B) from the reaping section to the threshing machine. Reference numeral 20.20 is an auxiliary auger arranged parallel to the cross-feed auger behind the left and right cross-feed parts 18', 18' of the cross-feed auger 18, that is, on both sides of the starting end of the vertical sheet conveyor 19. The direction of rotation and the twisting direction of the spiral plate are the same as that of the conveyor 9 auger, and 21 is a beater for feeding the culm provided above the terminal end of the vertical conveyor 19.

According to the above #I configuration, the cutting part 14 & the cutting blade 17
The culm from which the root of the stock has been cut off is pushed backward by the progress of the tit machine, or by the culm which has been successively cut down. Since the auxiliary augers 20, 20 are arranged behind both sides, the culm cut by the left and right sides of the cutting blade is transferred to the cross-feeding parts 18', 1 of the cross-feeding auger 18 on the stock base side.
8', the tip side is received on the auxiliary augers 20, 20, respectively, and the tips are gathered in the center with the attitude facing toward the threshing machine l side, and the culm cut by the center of the cutting blade. After merging, they are lifted up onto the vertical conveyor 19 while maintaining the above-mentioned posture by the lifting part 18# of the horizontal feed auger 18, and as a result, the husk culms are placed in the threshing machine with the tip of the husk in front. It will be supplied into the handling room 3. In this case, the augers 18, 20, and 20 catch the culm above the culm, which has been harvested at its base and falls backward, compared to the conventional case where the culm is rolled under the auger. This allows the distance between the cutting blade and the auger to be shortened.

As described above, the present invention provides a cutting section of a DC combine harvester in which a cross-feeding auger is installed horizontally behind the cutting blades, and a vertically-feeding conveyor is installed from the rear of the central portion to the entrance of the handling chamber of the threshing machine. The right and left sides of the reaped husk culms are held upward and the husk culms are held upward, and the husk culms are gathered together as a horizontal feeding part to the center, and the center part is used as a jumping part that jumps up the gathered husk culms onto the vertical feeding conveyor, In addition, since the structure is such that an auxiliary auger is provided behind the left and right cross-feeding parts of the auger to hold and cross-feed the tip side of the culm, the gap between the cutting blade and the cross-feeding auger does not need to be widened. In other words, without increasing the overall length of the reaping unit or the machine body, it is possible to feed the harvested husk culm to the threshing machine with the tip always in the lead, thereby improving the ability to thresh the husk culm. It is played.
