As such a grain transport device, the Utility Model 61-
As disclosed in Japanese Patent No. 43859, the end of the shaft of the bottom screw and the longitudinal transmission shaft are interlocked and connected via a bevel gear, and a sprocket fixed to the lower end of the longitudinal transmission shaft is fixed to the shaft of the vertical screw. The chain is wrapped around the sprocket,
The rotary power of the bottom screw is transmitted to the vertical screw through a vertical transmission shaft and a chain.

The characteristic configuration of the present invention, which was made to achieve the above object, is that the terminal end of the shaft of the bottom screw horizontally suspended at the bottom of the grain tank and the lower end of the shaft of the vertical screw are arranged vertically with respect to the rotation speed of the bottom screw. In a state where the rotational speed of the screw increases, the vertical screw and the lower end portion of the grain lifting tube housing the vertical screw are made larger in diameter than the upper portion, and the bottom portion is The diameter of the screw is larger than that of the casing at the end of the screw, and its functions and effects are as follows.

In other words, by interlocking and connecting the shaft of the bottom screw and the shaft of the vertical screw through a pair of bevel gears, the rotational power of the shaft of the bottom screw is directly transmitted to the shaft of the vertical screw. , sprockets, chains, and other parts and space for them are no longer required. Furthermore, by making the rotational speed of the vertical screw faster than the rotational speed of the bottom screw during transmission, a sufficient vertical conveyance amount can be secured as before. In addition, by making the diameter of the lower end of the grain lifting cylinder larger than the diameter of the end of the bottom screw, the grain delivery path narrowed by the bevel gear and its support part is expanded, and grains are prevented from stagnation. It will be carried out without any problems. Furthermore, by making the diameter of the lower part of the grain lifting cylinder larger than that of its upper part, in other words, by making the upper part the same diameter as before, the inner wall and the edge of the vertical screw in the grain lifting cylinder are The increase in the number of grains that are damaged due to getting caught in the gaps between the grains can be suppressed as much as possible. In short, by suppressing the expansion of the diameter of the grain lifting tube, the increase in the distance that could potentially damage the grain is suppressed.

る。 As shown in FIG. 1, the grain lifting device 3 has a vertical screw 6 installed inside a grain lifting cylinder 5, and the lower end of the shaft 6a of the vertical screw 6 is connected to the bottom screw 2.
The vertical screw 6 is interlocked with the terminal end of the shaft 2a via a pair of bevel gears 7 and 8 in an increased speed state in which the rotation speed of the vertical screw 6 is faster than the rotation speed of the bottom screw 2. Then, the diameter of the lower end portion of the vertical screw 6 and the diameter of the lower end portion of the grain frying tube 5 corresponding to that location are made larger than the upper portion, and larger than the casing portion 9 at the end of the bottom screw 2. It is set as. The reason why the rotational speed of the vertical screw 6 is made faster than the rotational speed of the bottom screw 2 is that it is generally necessary to make the vertical conveyance amount larger than the horizontal conveyance amount. The diameter of the lower end of the grain lifting device 3 has been expanded to compensate for the narrowing of the grain conveyance path by the bevel gear case 10 that pivotally supports the bevel gears 7 and 8. The grains conveyed by the bottom screw 2 are transferred to the vertical screw 6 without clogging.
This is to ensure that it is supplied to Furthermore, the reason why the upper diameter of the grain lifting cylinder 5 is made the same size as the normal diameter is to prevent the main body of the device from increasing in size, and at the same time, it is possible to fill the gap between the inner wall of the grain lifting cylinder 5 and the edge of the vertical screw 6. This is to suppress as much as possible the increase in the number of grains that are pinched and damaged.
