Description

[Detailed description of the invention] Industrial application field The invention enables grain to be filled and accommodated evenly on the left and right sides of the dryer main body by only rotating the scraping conveyor in one direction.
This invention relates to an improvement in a grain distribution device in a grain dryer that can accommodate a large capacity of grain and efficiently dry the grain even if the grain dryer is short in height.

Conventional technology Conventionally, a carry-in gutter is arranged at a certain interval directly below the center of the upper cover, and is formed so that grains are thrown diagonally upward to the left and right from the open top side of the carry-in gutter during the transportation process. At the very least, grain is accurately filled to the top cover position of the dryer body, and even a short grain dryer can accommodate a large capacity of grain and perform efficient grain drying work. The grain distributing device in the machine is known as described in, for example, Japanese Utility Model Application Publication No. 60-4897 before the present application, and the contents thereof will be explained with reference to FIG.

That is, the upper cover 2 covering the upper part of the dryer main body 1 has a dumping space 3 just below the center thereof, the upper surface of which is open, and a screw conveyor 6 is rotatably stored inside the dryer. The gutter 4 is arranged horizontally. On one side edge of the open side 5 of the carry-in gutter 4, left and right throwing guide bodies 9 each having a large number of throw notches 10 and dumping guide tongues 11 alternately provided are arranged so as to cover a part of the open side of the carry-in gutter 4. It has a configuration in which it is arranged at an angle. 7 is a screw blade, 8 is a rake plate, and 12 is an elevator.

Problems that the invention aims to solve By the way, in the conventional grain distribution device of this type of grain dryer, the grain is thrown in equal amounts in the left and right direction by the throwing action by one rotation of the rotating raking conveyor screw conveyor. However, the depth of the throwing notch provided on one edge of the open side facing the upward rotation direction of the delivery gutter and the height of the side wall facing the downward rotation direction were determined to Since the screw conveyor was installed at a higher position than the axis, the throwing force was inevitably reduced, and the throwing action of the scraping conveyor inevitably threw more grain than the throwing notch. There is less grain on the opposite side, and it is not possible to distribute the grain evenly on the left and right sides, but it is also impossible to distribute the grain in the same amount over the entire length of the inlet gutter. This results in a problem in which grains are distributed in such a way that there are many grains on the starting end side and the grains gradually decrease toward the conveyance side.

Means for Solving the Problems The present invention solves the above-mentioned problems, and the details thereof will be explained below using FIGS. 1 to 5 corresponding to the embodiments.

That is, a rotatable scraping conveyor 103 is installed at the upper part of the dryer main body 101.
is stored on a shaft rack, and there is a port 10 for dropping leftover grains at the end of the conveyance.
