Description

[Detailed Description of the Invention] The present invention relates to an improvement of a bucket for an elevator of a scoop-type grain dryer.

As shown in FIG. 1, the grain dryer has a box-shaped main body 1 which includes a storage section 2, a drying section 3, and a grain collecting section 4 in order from the top.
A bucket type elevator 5 is installed on the front of the main body 1.
is provided, and the grains carried out from the grain collecting section 4 are fried by the elevator 5. In the conventional direct dispersion type as shown in Fig. 2, the centrifugal force generated when the bucket is rotated in the upper pulley part pulls the grains in the bucket into the storage section 2 and acts as a kind of hindrance. A plate is provided to disperse the grains that have been picked up by the baffle plate. That is, as shown in FIG. 2, the upper edge of a closing plate 6 bent in a dogleg shape and serving as a guide is rotatably attached to an opening 5a provided in the upper part of the elevator 5. When carrying the grain into the storage section 2, the closing plate 6 is rotated to the position shown by the solid line to open the extraction port 5a, and the centrifugal force generated by the rotation of the bucket 7 moves the grain to the closing plate. 6, the particles collide with the blocking plate 6 and disperse, and are dispersed into the storage section 2 and dropped.

In addition, in order to discharge the drying material to the outside of the machine, the closing plate 6 is lowered as shown by the imaginary line, and the material is allowed to flow down from the flow gap 8 to the discharge gutter 9. However, this dispersion method has the disadvantage that sufficient dispersion cannot be achieved because the energy loss caused by the ejection energy of the grains being absorbed by the collision with the blocking plate 6 impairs the dispersion ability.

Therefore, in the present invention, in order to eliminate the above-mentioned drawbacks, the blocking plate is abolished, and instead, by improving the shape of the bucket itself, the grain is distributed to the left and right at the time of harvesting, so that it is sufficiently dispersed. This is what I am trying to do. To illustrate the state in which grains are being extracted from a bucket, as shown in FIG. (the wall opposite to the belt mounting wall 13), and is finally pulled out. Then, by changing the shape of the harvesting wall 12 and distributing the grain to the left and right, it is possible to widely disperse and harvest the grain. In this way, the retraction energy generated by the swinging of the bucket 7 is dispersed before it is deflected by air resistance during flight, so it can be efficiently dispersed.

Examples will be described below based on the drawings. 4th to 6th
The figure shows a first embodiment, and the bucket belt 20 is composed of a bottom surface 21 and a peripheral wall 22, and the peripheral wall 22 includes a belt mounting wall 22a on the rear surface, a retracting wall 22b on the front surface facing the belt mounting wall 22a, and side walls on the left and right sides. Consists of 22c. The upper part of the bucket bag 20 is open, and the upper part of the peripheral wall 22 is tilted outward so as to be wider than the bottom surface 21. An appropriate width of the middle upper part of the retraction wall 22b is bent inward at right angles to form a bent piece 23, which serves as a regulating member. In addition, the left and right sides of the pulling wall 22b are tilted upward and forward to form slanted side walls 22d.

According to this bucket bag 20, the grain is regulated from being picked up from the center by the bent piece 23, and is guided by the left and right side walls 22c and the diagonal side wall 22d that face diagonally forward, so that the grain is pulled from the left and right from the time of being picked. They will be allocated.

7 to 9 show a second embodiment. Bucket 24
It is the same as the first embodiment that it is composed of a bottom surface 25 and a peripheral wall 26, but in this embodiment, the
6b has a V-shaped rib 27a in plan view as a regulating member.
and a rib 27b having an inverted V-shape in plan view are provided at intervals and are symmetrical with respect to the center line of the retracting wall 26b. The ribs 27a restrict the picking from the center, and the grain is guided between the ribs 27a and 27b, thereby distributing the grain to the left and right.

10 to 12 show a third embodiment. The bucket 28 is composed of a bottom surface 29 and a peripheral wall 30, but instead of providing ribs, the bucket surface 30 of the peripheral wall 30 is
b is modified to provide the function of regulating the pull from the center. That is, by bending the portion of the retracting wall 30b that substantially faces the bottom surface 29 toward the center in a V-shape in plan view, the retracting wall 30b has a pair of left and right inner slopes A, A, and a pair of left and right outer slopes I, Divide into A and B. By distributing grain to the left and right by the opposing inner slopes A and A and the following outer slopes A and B, the same effect as when a regulating member is attached is produced.

Next, the operation of the above configuration will be explained. 1st
FIG. 3 is a side view showing the bucket of the present invention in a plucked state, and FIG. 14 is a plan view of the same, showing the storage section 31.
The upper opening 31a and the upper part of the elevator 32,
They are connected by a guide tube 33 with a flared tip end, and a discharge tube 34 is provided below the guide tube 33 for guiding the grains out of the machine. An upper damper 3 that closes the upper half of the opening 31a is provided at the upper edge of the opening 31a.
Similarly, the lower edge of the lower damper 36, which also serves as a switch for closing the lower half and simultaneously switching to the discharge pipe 34, is pivotally attached to the lower edge of the opening 31a. To transport grain from the elevator 32 to the storage section 31, the upper and lower dampers 35 and 36 open the opening 31a, and the lower damper 36 closes the discharge pipe 34.
Although it is the same as the conventional method that grains are pulled into the storage section 31 by the upper pulley 37 of the bucket 20, the bucket 20 of the present invention prevents the grain from being pulled from the center as described above. Since the grains are regulated and distributed to the left and right by the members, the grains are widely dispersed to the left and right as shown in FIG. In the same figure,
indicates the diffusion range by the conventional bucket and the diffusion range by the bucket of the present invention. When the drying is finished and it is to be discharged outside the machine, the upper and lower dampers 35,
The opening 31a is closed at 36, the discharge pipe 34 is opened, and the grains are discharged from the same pipe. In addition, when the throughput is smaller than the lifting amount of an elevator, such as a scrubbing machine, the upper damper 35 is left open as an overflow port.

As explained above, the bucket of the present invention is equipped with a regulating member on the plowing wall of the bucket to regulate the plowing from the center and distribute it to the left and right, so that grains can be directly transported by the bucket without a special dispersion device. Can be widely distributed to the left and right. Therefore, energy loss is reduced, assembly work is facilitated, and costs can be reduced.
