Description

[Detailed description of the invention] Industrial application field This invention prevents dust mixed in the dried paddy from accidentally scattering to the surrounding area when the dried paddy is transported to a desired location by a grain lifting machine. The present invention relates to a dry paddy sorting device in a paddy dryer.

Prior Art Conventionally, dried paddy that has been dried in a paddy dryer is discharged and stored in a receiving trough attached to one side of the dryer main body through a communication pipe by a switching operation of a switching valve, and then the dried paddy is stored. A grain lifting machine for use in a paddy dryer, in which the grains are transported to any desired location using a grain lifting machine attached to a receiving trough, is well known and was described in, for example, Japanese Utility Model Application Publication No. 1254/1983, prior to the filing of this application.

Problems that the invention aims to solve By the way, in the conventional equipment of this kind, even though the dry rice contains a lot of dust after drying, it is difficult to separate and remove the dust from the dry rice. Therefore, when dried paddy is transported to a desired location by a grain lifting machine, a lot of dust is ejected from the end of the grain lifting cylinder of the grain lifting machine together with the dried paddy, and this becomes dust. This not only causes the grain to be blown away by the grain wind, worsening the working environment, but also
A problem arose in that the efficiency of the dry paddy transportation work was significantly reduced.

Therefore, in the present invention, the dried paddy after being dried by the paddy dryer is supplied to the dust remover body, and the dust mixed in the dried paddy is removed from the dried paddy by wind sorting action, and then it is transferred to the grain lifting machine. Even if the desiccant is transported to an arbitrary location by the fried rice, dust is prevented from being accidentally scattered around together with the dried rice from the end of the grain-lifting cylinder, The above-mentioned problems have been solved by providing a dried paddy sorting device for a paddy dryer, which has the purpose of improving the working environment and promoting the efficiency of conveyance work.

Means for Solving the Problems Therefore, the technical problem of the present invention is to prevent dust from accidentally scattering to the surrounding area even when dried paddy is transported to an arbitrary location by a grain lifting machine. The goal is to prevent

In order to solve this technical issue, we have developed a structure in which the interior of the dust remover body above the air intake window is connected to the dry paddy flow lower passage where the upper end is connected to the dry paddy discharge gutter and the lower end is connected to the paddy discharge port, and the upper end is connected to the dry paddy discharge gutter. The side is divided into a dust removal blower, and the lower end is divided into a drying paddy flow down passage and a dust sorting air passage connected to the paddy discharge port, respectively, and the inside of the dust remover body below the air intake window is a dryer with a horizontally discharging screw. The paddy drying device is formed into a paddy box, and a grain lifting machine is attached to one side of the dust remover main body, the grain lifting machine being equipped with a grain lifting tube and communicating with the inside of the drying paddy box via a carrying-out screw. This is a dry paddy sorting device in the machine.

Function The technical means of the present invention works as follows (see drawings).

Now, if it is desired to transport only the dried paddy after drying to a desired location by the grain lifting action of the grain lifting machine, first, the dust blower 6 and the grain lifting machine 12 are operated. Then, due to the suction action of the dust blower 6,
The air sucked into the dust remover main body 1 through the air intake windows 2, 2 is sucked and distributed from the paddy discharge port 4 through the dust sorting air passage 7 toward the dust exhaust blower 6, and then is exhausted outside the machine. It carries out the action of

Therefore, if dried paddy containing more dust than the dried paddy discharge gutter 3 is supplied to the dry paddy flow lower passage 5, the dried paddy will flow down through the dried paddy flow lower passage 5 toward the paddy discharge port 4. The dried paddy and dust are efficiently separated by being exposed to the sorting air flowing through the dust selection air path 7 from the paddy discharge port 4 toward the dust blower 6, and only the dust with light specific gravity is removed from the dust separation air path 7. Along the dust removal blower 6
After being sucked into the air, the dust is concentrated outside the machine.

The carefully selected dry paddy from which dust has been removed through the wind sorting process is stored in the dry paddy box 10 located below the paddy discharge port 4.
The grains are then collected by a transport screw 11 to a grain hoisting machine 12, and then transported to an arbitrary location by the grain hoisting action.

Therefore, since the dust mixed into the dried paddy transported by the grain lifting machine 12 by the wind sorting action in the dust remover main body 1 has been removed in advance, it is difficult to know how to transfer the dried paddy to the grain lifting cylinder 13. Even when the dried paddy is transported to a desired location after drying, dust is not emitted from the end of the grain-lifting cylinder 13 into the surrounding area along with the grain-frying wind. This can be done efficiently under the
