Description

Description: [Industrial field of use] The present invention relates to a fried machine having a configuration in which a screw that is driven and rotated is axially mounted inside a fried cylinder, and a discharge port of the fried cylinder of the fried machine. The present invention relates to an improvement in a clogging prevention device that prevents clogging of grains that occur in the vicinity.

[Prior Art] The fried machine A of the above-described form is, as shown in FIG.
The rotary shaft 20 is provided inside the fried grain cylinder 1 which is tilted in the axial direction at a constant angle α with respect to a horizontal plane and is supported by a machine frame of a harvester or the like.
A screw 2 having a spiral wing 21 wound around it is mounted on the screw and driven to rotate, whereby the fried grain is connected from the discharge port 10 opened to the lower surface side of the upper end of the fried cylinder 1 to the fried grain. To the inside of the discharge cylinder part 3, and the outlet of the discharge cylinder part 3
Although it is made to flow out from 30 to the outside, in order to perform the work when packing the grains flowing out from the outlet 30 without confusion, the discharge cylinder part 3 is formed in a tank capable of storing the grains, and The bottom of it is branched into two outflow gutters 31 and 31 (one is cut off in the drawing), and outlets 30 are provided at the lower ends of these outflow gutters 31 ...
A paddy bag can be connected to the container, so that the grains discharged from the discharge port 10 of the fried cylinder 1 are guided to one of the outflow gutters 31 by the shutter 4 provided in the discharge cylinder part 3. When the inside of the paddy bag connected to the outflow port 30 of the outflow gutter 31 is full, the shutter 4 is switched by the operation of the operating rod 40 so that the other outflow gutter 31 can be guided.

When the grain is full in the paddy bag connected to one of the outflow gutters 31 and the grain is clogged in the outflow gutter 31 as well, the shutter 4 automatically releases the grain. In order to make it overflow into the other outflow gutter 31, the grain is attached to the side edge of the shutter 4 on the side opposite to the lower edge 10a of the discharge port 10 of the fried grain cylinder 1 in the grain feeding direction. A notch portion 41 through which grains flow is provided.

Then, from this fact, when the grain fed in the fried-grain barrel 1 by the screw 2 is discharged from the discharge port 10 into the discharge cylinder part 3, it flows toward the cutout part 41 side of the shutter 4. In order to avoid overflowing into the other outflow gutter 31, the screw 2 provided in the fried cylinder 1 is provided with a screw blade 2 at the terminal end side of the spiral blade 21 wound around its rotary shaft 20 in the lifting direction.
The grain that has been cut and pumped at a portion located downstream of the lower edge 10a of the discharge port 10 in the lifting direction is discharged from the end portion of the spiral blade 21 as shown by a chain line in FIG. The imaginary line W connecting the lower edge 10a of the outlet 10 corresponds to the level according to the angle of repose of the grain, and the level naturally holds while maintaining that level. I try to run down.

[Problems to be Solved by the Invention] By the way, in the fried machine A configured as described above, the grain is also full in the paddy bag connected to the outflow gutter 31 on the side where the overflowing grains are discharged. If you don't know that the grain is being discharged, or if you have to replace the paddy bag late, the grain may become completely clogged from inside the discharge cylinder 3 to inside the fried cylinder 1. Then, even if the paddy bag is replaced and the grains in the discharge cylinder part 3 are discharged, as shown by hatching in FIG. 2, the upper half circumference as seen from the axial direction in the fried food cylinder 1 is shown. At the side part Y, the grain is clogged so that it does not come down and a phenomenon occurs that makes the fried grain work impossible.

In order to avoid this phenomenon, in the prior art, a scraping plate 5 is provided at the terminal end of the rotary shaft 20 of the screw 2 from which the spiral blade 21 is removed in the lifting direction, as shown in FIGS. 3 and 4. A bridge is provided between the bearing portion 11 on the terminal end side of the lifting cylinder 1 in the lifting direction and the grain layer that has been lifted up to the turning locus of the terminal end 21a of the spiral blade 21. The edge portion of the grain group that is causing the phenomenon is scraped out by the scraping plate 5 to destroy the bridge, so that the grains that are clogged on the upper half side of the fried cylinder 1 described above and collapsed are collapsed. I have to.

However, with this means, when the grain is not clogged in the fried-cylinder 1 and the discharge cylinder 3, and the screw 2 is operating normally, it flows out from the discharge port 10 into the discharge cylinder 3. There is a problem in that some of the grains are scattered by hitting the scraping plate 5, and the scattered grains flow to the notch 41 side of the shutter 4 serving as an overflow port.

The present invention has been made in order to solve this problem, and clogging of the grain that occurs near the discharge port of the fried cylinder while effectively preventing the grain from scattering and flowing to the overflow port. The purpose is to provide a new means to eliminate the.

[Means for Solving the Problems] The present invention, however, has been completed based on the findings obtained through various studies to solve the above problems.

That is, when the grain is fully packed in the fried-cylinder 1, the grain stuffed tightly around the rotary shaft 20 of the screw 2 in the fried-cylinder 1 without the spiral wing 21 is By scraping off the lower end side of the part in the lifting direction, the bridge will be destroyed and the part will be scraped off.
Even if the space between the inner peripheral surface of the fried food barrel 1 and the inner peripheral surface of the fried food container 1 is not completely scraped off, a part of the grain is further screwed, as shown by being surrounded by a chain line Z in FIG. By locally scraping off only the very close part around the rotation axis 20 of No. 2, the crushed grain began to collapse, and the result was that it gradually unwound the whole grain. In order to locally scrape off only the periphery of the rotary shaft 20 of the screw 2 in this way, a scraping body whose protrusion height from the peripheral surface of the rotary shaft 20 is extremely low is used. The part where the spiral blade 21 of the surface is cut may be provided in a state where it is continuous with the terminal end portion of the spiral blade 21, and when a scraping body is provided in this manner, almost all of the scattered particles of the grain can be produced. Without
This is because it is possible to remarkably reduce the number of scattered particles flowing in the notch 41 of the shutter 4 which is the overflow port.

From this, therefore, in the present invention, as a means for achieving the above-mentioned object, the fried food barrel 1 which is supported on the machine frame by inclining the axial direction at a constant angle α with respect to the horizontal line.
Inside, a screw 2 for hoisting a grain, which is equipped with a spiral blade 21 around a rotating shaft 20, is hung, and a discharge port is provided on the lower peripheral surface side of the terminal end of the hoisting barrel 1 in the hoisting direction. Opened 10 and its outlet
A discharge tube portion 3 having a plurality of outflow gutters 31 at the bottom thereof is connected to 10, and the grains flowing out of the discharge port 10 are guided to the inside of the discharge tube portion 3 by switching to the plurality of outflow gutters 31. The shutter 4 is installed and the shutter 4
A notch 41 serving as an overflow port is formed on the opposite side of the discharge port 10 from the lower edge 10a in the lifting direction, and the spiral blade 21 of the screw 2 described above has its end side in the lifting direction set to the discharge side. In the grain elevator A, which is cut out at a position lower than the lower edge 10a of the outlet 10 in the lifting direction, the terminal end side of the spiral blade 21 on the peripheral surface of the rotary shaft 20 of the screw 2 is set to the spiral blade.
Lower end 1 of the end portion 21a of 21 and the discharge port 10 in the lifting direction
A virtual line W connecting with 0a is cut off so as to correspond to the level according to the angle of repose of the grain in the fried cylinder 1, and the spiral blade 21 on the peripheral surface of the screw 2 on the terminal end side of the rotary shaft 20 is cut off. In a region extending from the terminal end 21a of the spiral blade 21 to above the lower edge 10a of the discharge port 10, the spiral blade 21 rotates at a protrusion height h much lower than the radial protrusion height of the spiral blade 21. A scraping body a protruding from the peripheral surface of the shaft 20 is installed along the peripheral surface of the rotating shaft 20, and the starting end side of the scraping body a in the feeding direction is set to the terminal end portion 21a of the spiral blade 21. The present invention proposes a grain clogging prevention device in a fried machine, which is characterized by being made continuous.

Example Next, an example will be described in detail with reference to the drawings. The reference numerals used in the drawings are the same as those used in the conventional means for components having the same effect.
