Description

[Detailed Description of the Invention] The present invention relates to a grain storage device for a combine harvester, in which both a tank and a paddy bag can be used as a storage means for harvested grain, as required.

By the way, a tank or a paddy bag is used as a grain storage device in a combine harvester, and conventional combine harvesters were manufactured from the beginning with a tank specification or a bagging specification, and models with either specification were later changed to other specifications. It was not possible to change the specifications. Therefore, it has not been possible to adapt the device to changes in the field or other working environment or to the relationship with other tasks during use, which has been a factor that has hindered improvements in work efficiency.

This device was developed in consideration of the above-mentioned situation, by providing a removable tank on the side of the threshing section, and a removable vertical conveying device for storing and bagging in the tank connected to the first screw in the threshing section, either on the side of the tank, or on the side of the threshing section when the tank is removed, making it possible to use either the tank or rice bags as needed as a means of storing grain, thereby allowing the most appropriate storage means to be freely selected in relation to the working environment and other tasks, significantly improving work efficiency.

Hereinafter, this will be explained with reference to the embodiment shown in the drawings. In FIG. The threshing section is equipped with threshing and sorting devices such as a handling barrel 5, a receiving net 6, and a swinging sorting plate 7, and a first screw 8 for carrying out grains is provided at the bottom. 9 is a tank installed on the platform 4 on the side of the threshing section 3;
Reference numeral 10 denotes a vertical conveyance device attached to the side thereof, in which a screw 12 housed in a cylindrical body 11 is connected to the first screw 8 via an intermediate screw 13 provided at the bottom of the tank. At the same time, the upper end of the conveying device is equipped with a rotatable grain ejector 14 into the tank, and the upper part of the intermediate screw 13 at the bottom of the tank is covered with a shutter 15 that is opened during the discharging operation. ing. The shaft 8a of the first screw, the shaft 13a of the middle screw, and the input shaft 10a of the vertical conveyance device are separably connected by spline sleeves 16 and 17, respectively, and the tank 9 and the vertical conveyance device 10 are detachably connected. Moreover, the conveying device can be installed adjacent to the threshing section 3 with the input shaft 10a directly connected to the shaft 8a of the first screw, as shown in FIG.

According to the above configuration, when the tank 9 is installed on the side of the threshing section 3 and the vertical conveyance device 10 is attached on the side as shown in FIG. The separated and sorted grains pass through the first screw 8, the intermediate screw 13 at the bottom of the tank, and the vertical conveyance device 10, and are then transferred to the discharge tube 14.
It is then put into the tank. Also, the second
As shown in the figure, the tank 9 is removed, the vertical conveyance device 10 is installed adjacent to the threshing section, the input shaft 10a of the device is directly connected to the shaft 8a of the first screw, and the discharge cylinder 14 is connected to the threshing section. If it is rotated toward the section side, the grains carried out by the first screw 8 from the threshing section will be stored in the paddy bag 18 installed on the table 4 via the vertical conveyance device 10 and the discharge cylinder 14. In this way, the grain can be stored in tanks and bagged. In this embodiment, a support rod 19 for the paddy bag is attached to the side wall of the threshing section so that it can be set in a horizontal position as shown in FIG. 2 during bagging. Sometimes an extension tube 20 is used which is connected to the tip of the discharge tube 14, but the extension tube is branched into two forks as shown in FIG. 3, and the branch is equipped with a switching valve 20a'. By using the extension tube 20', two paddy bags 18', 1
8' may be set simultaneously. still,
When discharging the grains in the tank 9, it is sufficient to open the shutter 15 above the intermediate screw 13 and operate each screw with the discharge tube 14 directed toward a transport vehicle or the like.

Next, the embodiment shown in FIG. 4 will be explained.
3' is a threshing unit, 9' is a tank removably installed on the side thereof, and 10' is a vertical conveyance device also removably installed on the side of the tank, and the input shaft 10a' of the device is is the most screw 8'
shaft 8a' or intermediate screw 13' at the bottom of the tank.
By being connectable to the shaft 13a' of
Similar to the previous embodiment, grains can be stored in a tank or packed into bags, but in this embodiment, a deck 2 for placing paddy bags is connected to a frame base 4'.
1' can be pulled out to the side, and a paddy bag support rod 22' is provided on the outer surface of the tank 9'.
It is designed so that bagging work can be carried out with the equipment equipped.

As described above, the present invention has a tank removably installed on the side of the threshing section, a vertical conveyance device that is also removably installed on the side of the tank opposite to the threshing section, and the device is attached to the threshing section. Since the structure is such that it can be connected to the first screw at the bottom of the tank through the intermediate screw at the bottom of the tank when the tank is installed, or directly when the tank is removed, the tank and the screw can be used as grain storage means. It is now possible to use paddy bags freely as needed, and this makes it possible to always select the most suitable storage means depending on the work environment or relationship with other work, which greatly improves work efficiency. In particular, according to the present invention, since the vertical conveyance device is used for both tank storage and bag filling, there is an advantage that there is no significant cost increase.
