Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a de-awning machine that efficiently removes awns (referred to as awns) from paddy.

[Conventional technology]

Conventionally, this type of awning machine has a cylindrical body with a paddy storage hopper connected to one end and a discharge port at the other end suspended horizontally on the machine frame. It has a spiral transport body inside.
(For example, Utility Model Publication No. 59-28677, Utility Model Publication No. 45-
(Refer to Publication No. 9565) [Problem to be solved by the invention] This type of device aims to mix and rub the paddy grains together in a cylindrical body while transporting the paddy grains using a transporting body.
The awns of the paddy are removed by this rubbing action. Therefore, since the paddy and awns are discharged together from the discharge port of the cylinder, it is necessary to use wind power to separate them at the discharge end of the cylinder, which requires extensive equipment. The post-processing of the blown-off awns also requires manpower. In addition,
There is an inconvenience in that it is not possible to completely remove the awns by simply rubbing the paddy together.

In addition, since conventional awning machines have a single cylindrical structure, a long cylindrical body is required to completely remove the awns from the paddy, making the machine itself longer and reducing the installation space. There were issues with handling, such as the large amount required.

The purpose of the present invention is to effectively cut and remove awns using a small elongated hole provided in a cylindrical body, and also to release and collect the removed awns downward from this small hole, thereby eliminating the need for a wind selection mechanism, etc. Moreover, it is an object of the present invention to provide an awn removal machine with high awn removal efficiency at a low cost.

[Means to solve the problem]

The structure of the present invention that solves the problems of the conventional technology is as follows:
A cylindrical body is connected to the opening of the paddy storage hopper at the top of one end, has a discharge port at the other end, and has a large number of small holes formed below the center.
In the awning machine, which has a spiral transfer body inside the cylindrical body along the axial direction of the awning machine, a relatively short first cylindrical body having a hopper for storing the paddy at one end is connected to the machine frame. The body 2a and the second cylindrical body 2b having the discharge port on the downstream side are arranged adjacent to each other in parallel,
The lower side of the first cylindrical body 2a and the upper side of the adjacent cylindrical body 2b are connected by a passage 4, and a transfer body 7 in the first cylindrical body 2a corresponding to this passage 4
A vane plate 9 for transporting the paddy in the perpendicular direction is provided at the a end, and the small holes 6a and 6b formed in the first and second cylindrical bodies 2a and 2b are elongated, and the longitudinal direction thereof is 1 and the second cylindrical bodies 2a, 2b are disposed perpendicularly to the axial direction thereof.

Further, a pulley 11 is attached to an end of a shaft 10 of the transfer body 7a that can protrude outside the machine frame 1.

Furthermore, a transfer body 7b having a diameter close to the inner surface of the second cylindrical body 2b is mounted on an internal shaft, and this transfer body 7b has a width that allows the paddy to roll, and A spiral groove 8b is formed to transfer the paddy from the passage 4 toward the discharge port 5. Further, a screw 12 is provided on the upper side of the transfer body 7b to feed the sent paddy toward the transfer body 7b.

A pulley 14 is provided on a shaft 13 that protrudes outside the machine frame 1 from the upper side of the transfer body 7b, and a pulley 17 attached to a shaft 16 of a motor 15 provided on the machine frame 1 and the pulley 11 ,1

[Explanation of action]

Next, the operation of the above embodiment will be explained.

The paddy stored in the storage hopper 3 is stored in the opening 3a.
enters the first cylindrical body 2a, and is sequentially conveyed to the lower side while rolling within the spiral groove 8a of the conveying body 7a,
During this transportation, the awn of the paddy is formed into a small hole 6 with an elongated shape.
A was intervened and removed.

The paddy is then transferred to a wing plate 9 provided at the end of the transfer body 7a.
The awns are transferred into the other second cylindrical body 2a through the passage 4, and are efficiently sent to the transfer body 7a by the action of the screw 12, and are removed from the awns by the same action as described above and released from the discharge port 5. , are stored in the paddy collection box 21. Further, the excised awns are collected in the awn collection box 19.

〔effect〕

As described above, according to the configuration of the present invention, the following effects can be obtained.

(a) It goes without saying that the paddy stored in the storage hopper can be removed by the awns while being rolled by the transfer body; (b) In the present invention, at least the center of the first and second cylindrical bodies A large number of small holes were formed in almost the entire area of the lower part, and the small holes were made into an elongated shape, and the longitudinal direction of the small holes was made perpendicular to the axial direction of each cylindrical body. The awn that rolls along the inner surface of the second cylindrical body easily intervenes in the small hole, and the transfer action of the transfer body and the rolling action of the paddy cause the awn of the paddy to be shaved as if it were being shaved with an electric razor. The awns can be removed efficiently, and the awns that have been removed are allowed to fall down and be collected through the small holes, and the means of separating paddy and awns by wind sorting as in the conventional technology can be omitted, simplifying the device. can be planned. Furthermore, there is no need for manpower to dispose of scattered awns, unlike in the conventional method.

(c) In the present invention, a plurality of first and second cylindrical bodies are arranged parallel to each other in parallel to the machine frame, and these can be communicated in a meandering manner, so that the machine frame does not have to be made long as in the conventional case. In addition to simplifying handling,
The machine frame can be made much more compact.
