Description

[Detailed description of the invention] [Field of industrial application] The present invention is a grain dryer in which the grain loaded inside the dryer body can be transported from either the elevator side or the thrower side provided on the opposite side. This relates to a grain discharge device that enables grain discharge.

[Prior Art] Conventionally, an elevator was attached to one side of the dryer body to load and circulate grain inside the dryer body.
A grain dryer in which one end of a lower screw conveyor provided in the lower part of the dryer main body is connected to an elevator is widely known, as described in, for example, Japanese Utility Model Publication No. 12547/1983. This grain dryer is constructed as shown in Fig. 3, where 1 is the dryer main body;
2 is an elevator, 3 is a lower screw conveyor, and 4 is a grain discharge port of the elevator 2.

In addition, a structure in which a jump grain thrower is connected to the discharge port of an elevator attached to a grain dryer to lift and transport grain is available, for example.
It is described in Publication No. 59-189091.

[Problems to be solved by the invention] By the way, in conventional grain dryers of this type, the grain loaded inside the dryer body is discharged from the lower screw conveyor via an elevator. When discharging grain to the side opposite to the elevator attached to the main body of the dryer, it is necessary to attach a large thrower to the elevator that has the ability to transport the grain a long distance to the opposite side of the main body of the dryer.
As the grain discharging device is large-scale, it also has problems such as complicated operation.

The present invention was devised in view of the above-mentioned problems of the conventional technology, and its purpose is to discharge grain after drying by using a thrower device even from the opposite side of the elevator. It is an object of the present invention to provide a grain discharging device in a grain dryer that can be easily performed.

[Means for Solving the Problems] In order to achieve the above object, the grain discharging device in the grain dryer according to the present invention has a main body 1 of the dryer.
An elevator 102 is attached to one side of the dryer main body 101 for feeding and circulating grain, and the elevator 102 is attached to one end of a lower screw conveyor 103 horizontally installed at the lower part of the dryer main body 101. Make the connection. A lower screw conveyor 1, which can freely rotate in forward and reverse directions, has one end connected to an elevator 102.
03 to the outside of the dryer main body 101,
This provides a grain discharge port 104 at the end, and the grain discharge port 104 is provided with a thrower device 10.
8 are detachably connected.

[Function] The grain loaded in the dryer main body 101 is moved to the elevator 1.
When discharging to the 02 side, first, the lower screw conveyor 103 is rotated in the forward direction, and the grains are sequentially conveyed toward the elevator, lifted by the elevator 102, and discharged from the upper discharge port. When the grain is discharged from the opposite side of the elevator 102, the thrower device 108 is connected to the grain discharge port 104 at the other end of the lower screw conveyor 103, and then the lower screw conveyor 103 is rotated in the opposite direction. , the grain is discharged by a thrower device 108 to the opposite side of the elevator 102 .

[Example] Examples will be described with reference to the drawings.

1 and 2, 101 is a dryer main body, on one side of which is a dryer main body 10.
Elevator 1 for loading and circulating grain inside 1
02 is attached. In addition, the dryer main body 101
A lower screw conveyor 103 is installed horizontally at the lower part of the inside. One end of the lower screw conveyor 103 is connected to the elevator 102,
The other end side is extended to the side opposite to the elevator 102, and a grain discharge port 104 is formed at this extended end portion.
05 is provided so that it can be opened and closed freely. Reference numeral 106 denotes a grain delivery roll disposed at the lower part of the dryer main body 101. Reference numeral 107 denotes a forward and reverse rotation motor, and this forward and reverse rotation motor 107 drives the lower screw conveyor 103.

A thrower device 108 is detachably connected to the grain discharge port 104 of the lower screw conveyor 103. That is, reference numeral 109 denotes the connecting tube, and the connecting tube 109 and the thrower device main body 110 communicate with each other, and the screw conveyor 111 in the connecting tube 109 and the thrower blade 112 in the thrower device main body 110 communicate with each other. It rotates as one. The connecting cylinder portion 109 is connected to the lower side of the grain discharge port 104 of the lower screw conveyor 103. In addition, the thrower blade 112
The screw conveyor 111 is connected to the dryer main body 1 by a dedicated motor or an appropriate transmission means.
It is rotated by receiving power from the 01 side. 113 is a lifting gutter, and 114 is a grain storage tank.

In the structure configured as described above, when discharging grain from the dryer main body 101 to the elevator 102 side, the forward/reverse rotation motor 107 is rotated in the forward direction to transport the grain on the lower screw conveyor 103. The direction is the elevator 102 side.

In addition, when discharging grains to the side opposite to the elevator 102 of the dryer main body 101, the forward and reverse rotation motor 107
The lower screw conveyor 103 is rotated in the opposite direction.
If the lifting direction of
Since the grains are transported in the 04 direction, they can be discharged to a desired location by the thrower device 113 connected to the grain discharge port 104.

In this way, by simply rotating the lower screw conveyor 103 in the forward and reverse directions, the grains in the dryer main body 101 can be arbitrarily discharged from the elevator 102 side or from the opposite side by the thrower device 113. Thrower device 1 allows grain to be discharged smoothly and efficiently depending on the working conditions.
The grain discharging device 13 is not large-scale and can be easily operated.

[Effects of the invention] Since the present invention is configured as described above, it produces the following effects.

By simply rotating the lower screw conveyor 103 forward and backward, the grains in the dryer main body 101 can be transferred to the elevator 1.
The grain can be discharged from the 02 side or from the opposite side by the thrower device 113, and the grain can be discharged smoothly and efficiently depending on the working conditions. The ejecting device is not large-scale and can be easily operated.
