Description

[Detailed description of the invention] This invention has a grain equalizer installed in the upper center,
The center of the vertical hanger pipe is fixedly supported on the grain tank at the center of the upper part of the cylindrical or polygonal grain tank, which has a discharge outlet in the center of the bottom and is configured to send drying air from below. A hanger that rotates is provided, a revolving shaft that revolves around the hanger is spanned between the hanger and a rail provided on the inner surface of the peripheral wall of the grain tank, and a stirring device consisting of a vertical auger is installed on the revolving shaft. The present invention relates to an improvement in a grain drying device in which a temperature measurement cable for detecting grain temperature passing through the hanger pipe is suspended from the center of the grain tank.

In the conventional grain drying device of this kind, as shown in FIG. Since the temperature measuring cable 33 is perpendicular to the axis of the vertical auger 29, when passing the temperature measuring cable 33 through the inner cavity of the hanger pipe 12, the temperature measuring cable 33 must avoid the revolution axis 19 of the vertical auger 29, etc. Furthermore, when the vertical auger 29 performs operations such as rotating while revolving, the installed temperature measurement cable may be twisted and cut, causing the problem that the grain temperature cannot be detected properly. Further, since the support hanger such as the revolution shaft 19 and the hanger pipe 12 are constructed as one unit, the bending moment applied to the support hanger is directly applied to the hanger pipe 12, and the hanger pipe 12 is strained. .

The present invention was devised in order to solve these problems in the conventional technology, and the revolution axis of the vertical auger and the gear motor axis do not interfere with the temperature measurement cable, and the action of the temperature measurement cable is controlled. reliably and
It is an object of the present invention to provide a new grain drying device that allows grain drying to be carried out properly and prevents twisting of a hanger pipe.

2 is provided.

Further, in the center of the grain tank 3, a temperature measurement cable 33 for detecting grain temperature passing through the hanger pipe 12 is installed vertically along the axis of the hanger pipe 12 to extend the space inside the vertical frame 14. It is arranged so that it hangs down. As shown in FIG. 2, the upper end of the temperature measuring cable 33 is tied to a pin 34 horizontally suspended above the hanger pipe 12, and the lower end thereof is

Next, the grain drying apparatus A configured as described above is
Explain the effect of

When grains are inputted from the loading hopper 11 and the conveying device 6 is operated, the grains supplied to the upper center of the grain tank 3 are uniformly dispersed by the centrifugal action of the equalizer 1. , the floor net 7 of the grain tank 3
stored above.

Drying air is forced into the grain tank 3 from below by an air blower 10, and inside the grain tank 3, vertical augers 29 and 30 first rotate while revolving around the grain, moving the grains vertically and circumferentially. A stirring action is applied while transferring the material in the direction and reciprocating direction along the radius.

During this period, the revolving shaft 19 rotates by receiving the rotational output from the operation of the gear motor 22 by the sprocket 24, chain 26, and sprocket 25, but the load applied to the vertical augers 29 and 30, and therefore the load applied to the revolving shaft 19. is received by the horizontal frame body 16 via the bearing portion 21 and the support member 23. The horizontal frame body 1
6 is connected to the vertical frame 14 by a pivot shaft 15 extending in a direction that intersects the extension of the axis of the hanger pipe 12, so that the moment around the pivot shaft 15 causes the vertical frame 14 to Therefore, the hanger pipe 12 is rarely subjected to twisting action. Also,
Since the vertical frame body 14 is loosely fitted around the outer periphery of the hanger pipe 12, the vertical frame body 14 and the hanger pipe 12 are less likely to be subjected to twisting action due to the horizontal moment applied to the horizontal frame body 16. . Therefore, the temperature measurement cable 33 disposed along the axis of the hanger pipe 12 is not interfered with, such as torsion, due to the operation of the revolution shaft 19.

When a predetermined grain temperature is detected by the temperature measuring cable 33, the horizontal auger 32 is activated and conveys the grain to the discharge port 2 while revolving along the floor net 7.

As described above, according to the grain drying device of the present invention, the operation of the revolution axis of the stirring device and the gear motor shaft does not interfere with the temperature measurement cable by twisting, etc., and the operation of the temperature measurement cable is ensured. Moreover, it can be done properly, and there is no need to put stress on the hanger pipe, such as twisting.
