Description

[Detailed description of the invention] The present invention is a grain dryer that circulates and dries grains loaded in a grain tank. This invention relates to an improvement in a grain flow promoting device which is constructed by installing a flow adjustment plate on the inner side of the machine wall of a grain tank in order to smooth the flow of grain along the inner surface.

In a circulation-type grain dryer, the upper part of the grain tank that holds the grains to be dried is formed into a storage part that receives a large amount of grain, and the bottom part is used to blow drying air onto the grains that sequentially flow down from the storage part. The grains that have passed through the drying section are returned to the storage section for circulation. Among these circulating grains, the grains located along the inner surface of the machine wall of the storage section of the grain tank have poor flow down, so the grains located inside the machine wall of the grain tank are As shown in FIG. 1, a flow adjustment plate 2 is installed at a location slightly inwardly and inclined so as to gradually move away from the machine wall 10 of the grain tank 1 toward the lower end. It is designed to promote the flow of grains along the inner surface.

By the way, the flow adjustment plate 2 provided in the grain tank of the circulating grain dryer is inclined so as to move away from the machine wall 10 as it goes downward, so that the grain flow path along the inside of the machine wall 10 is adjusted. By making W gradually become wider as it faces downward, the flow of grains flowing down along the inner surface of the machine wall 10 is smoothed. ,
On the contrary, since the flow path of grains becomes gradually narrower downward, there is a problem that the flow of grains flowing down the inside position of the flow adjustment plate 2 is obstructed.

The present invention was devised to solve this problem, and the present invention has been developed to provide a grain flow promoting device that is constructed by providing a flow adjustment plate on the inner side of the machine wall of the grain tank. While ensuring smooth flow of grains from the inside of the machine, the flow of grains is promoted in the flow path along the inner surface of the machine wall formed between the outer surface of the flow adjustment plate and the inner surface of the machine wall. The purpose is to provide a new means of configuring the

In this invention, for this purpose,
As shown in FIG. 2, a flow adjustment plate 2 that forms a grain flow path W between the inner surface of the machine wall 10 of the grain tank 1 and the inner surface of the machine wall 10 is installed on the machine wall 10 of the grain tank 1. The grain dryer is equipped with an inclined guide wall 20 which is arranged parallel to the flow adjustment plate 2 and which projects downwardly toward the machine wall 10 for a short length of time. It is intended to raise a facilitator.

Next, an example of implementation will be described in detail with reference to the drawings. In addition,
The same reference numerals in the drawings are used for components having the same effect.

Figure 3 is a partially cutaway front view of a circulating grain dryer A that can implement the present invention, where a is a square box-shaped machine body, and 1 is a part of the four peripheral walls of the machine body a. 1a is a storage part formed in the upper half of the grain tank 1, 1b is a drying part formed in the bottom of the grain tank 1,
Reference numeral 11 denotes an outlet of the grain tank 1 provided at the lower end of the drying section 1b, 3 a drum shutter provided at the outlet 11, and 4 the grain in the grain tank 1 discharged by the drum shutter 3. a screw conveyor for carrying out grains installed at the bottom of the bore of the machine body a to carry them out; 2 shows the elevator (bucket elevator) installed on the outside of the grain tank 1, and the flow adjustment plate 2 is installed inside the machine wall 10 of the grain tank 1 and constitutes the grain flow promotion device B. ing.

As shown in FIG. 4, the flow adjustment plate 2 is a long flow adjustment plate 2 disposed inside the left and right machine walls 10, 10 (removed in FIG. 4) of the grain tank 1. -1, 2-1, and short flow adjustment plates 2-2, 2-2 to be placed inside the machine walls 10, 10 before and after the grain tank 1.
The short flow adjusting plates 2-2, 2-2 have mounting plates 21 provided at each side end thereof, as shown in FIG.
..., the grain tank 1 of the long flow adjustment plates 2-1, 2-1
By coming into contact with the side surface of the inner surface 2a side with the center of the plate as a reference and fixing it together with the setscrews 22..., it can be assembled and supported by the long flow adjustment plates 2-1, 2-1, and the same As shown in Fig. 5, the long flow adjustment plates 2-1, 2-1 are assembled into a cross-shaped frame together with the long flow adjustment plates 2-1, 2-1, and protrude from the four corners of the frame. By joining the mounting plates 21 at each side end to the inner surfaces of the front and rear machine walls 10 of the grain tank 1 and fixing them to the machine walls 10 with setscrews 22, as shown in FIG. As shown in FIG. 1, it is installed on the aircraft body a inside each aircraft wall 10 in a position parallel to the aircraft wall 10.

Each of the flow adjustment plates 2... is provided with an inclined guide wall 20 on its upper end edge, which projects downwardly toward the opposing machine wall 10 for a short length of time. As shown in FIG. The distance between the outer surface 2b of the flow adjustment plate 2 and the inner surface of the machine wall 10 is narrowed by the amount by which the inclined guide wall 20 protrudes,
In most of the portions below the inclined guide wall 20, the gap is widened to the same distance as the outer surface 2b of the flow adjustment plate 2 and the inner surface of the machine wall 10. Note that a reinforcing rib 23 made of a bent edge may be provided on the lower edge of the flow adjustment plate 2, as shown by the chain line in FIG.

The apparatus of this embodiment operates as follows.

Flow adjustment plate 2 provided inside the machine wall 10 of the grain tank 1
The grain flow path W formed between the outer surface 2b of the machine wall 10 and the inner surface of the machine wall 10 is approximately equal from the upper end to the lower end because the flow adjustment plate 2 is oriented parallel to the machine wall 10. Regarding the spacing width, only the entrance portion at the upper end is narrower because the inclined guide wall 20 that slopes downward toward the machine wall 10 is installed at the upper end of the flow adjustment plate 2.

For this reason, the grains flowing down along the inner surface of the machine wall 10 and flowing into the flow path W pass through the inclined guide wall 20 at the entrance of the flow path W and enter the flow path W, where there are gaps between particles. The pressure of the water is rapidly reduced, and the water flows smoothly down the flow path W.

Since the flow adjustment plate 2 that forms the flow path W inside the machine wall 10 is in a posture parallel to the machine wall 10, the inner surface 2a facing the center of the grain tank 1 is also approximately vertical. , the flow path for grains flowing down the inner surface of the flow adjustment plate 2 is not narrowed.

As explained above, the grain flow promoting device in the grain dryer according to the present invention is arranged so that the grain flow promoting device in the grain dryer according to the present invention
By setting the flow adjustment plate 2 installed at the inside position of 0 in a vertical position parallel to the machine wall 10, and providing an inclined guide wall 20 that slopes downward toward the machine wall 10 at its upper end, The flow path W formed between the flow adjustment plate 2 is narrow at only the inlet and the inner bosom beyond it is wide, so that the pressure between grain particles flowing into this flow path W is reduced. Since the flow of grains is made to flow smoothly by reducing the It can smooth the flow.
