Description

[Detailed description of the invention] The present invention uses the flip-up action of a flip-up impeller that can easily collect some of the paddy immediately after it has been dried by the dryer and transports it to the elevator side. The present invention relates to a moisture detection device for a rice dryer, which can automatically and accurately detect moisture in rice at any time to achieve better rice drying work.

In the case of a paddy dryer that dries the paddy to a predetermined moisture content by circulating and drying the paddy while returning the paddy carried out from the dryer to the dryer several times via an elevator, the drying of the paddy is Detecting the condition from time to time is not only important for obtaining high-quality dried paddy, but also for fuel conservation and maintenance management.

By the way, in view of the above, many developments have been made to automatically detect the moisture content of circulating paddy, but all of them have complicated configurations of devices for collecting paddy. Of course, there are various inconveniences in terms of operability, inspection, and maintenance management, and it takes a considerable amount of time to detect the moisture in dried paddy, and as a result, the moisture in the paddy changes due to the influence of outside air conditions, etc. However, it was not possible to easily perform accurate moisture detection work at any time.

In view of the above, the present invention aims to provide a moisture detection device for a rice dryer which automatically extracts some of the rice that has been dried in a dryer and which has been transported from the dryer through the discharge trough and supply trough to the bottom of the elevator by the lifting impeller using the lifting action of the lifting impeller before the rice is affected by the outside air, and allows the moisture in the extracted rice to be accurately detected at any time by a non-crushing automatic moisture detector stored in the rice removal passage, thereby simplifying the rice collection work during moisture detection, further improving operability, inspectability and maintenance, and achieving more accurate moisture detection.The following is an explanation of a preferred embodiment of the device of this invention, as shown in the accompanying drawings.

In the drawings, reference numeral 1 denotes a dryer that can dry the paddy to a predetermined moisture content by exposing it to drying air while it is flowing vertically; in the present invention, a suction type dryer 1 is shown. ing. Reference numeral 2 denotes an elevator attached to one side of the dryer 1, and the upper part of the elevator 2 is connected to the supply start end side of a carry-in gutter 3 installed horizontally at the upper position of the dryer 1.
The lower part of the dryer 1 is connected through a supply gutter 4 integrally attached to one side of the lower part of the elevator 2 to an ejection terminal side of an ejection gutter 5 horizontally installed on the bottom side of the dryer 1. A carry-out screw shaft 6 is rotatably mounted in the carry-out gutter 5 for smoothly carrying out the paddy which has been exposed to drying air and dried to some extent into the supply gutter 4 through the carry-out gutter 5. One end of the unloading screw shaft 6 passes through the inside of the supply gutter 4 and is mounted on the side wall of the supply gutter 4.
A plurality of flip-up impellers 7 are attached to the discharge screw shaft 6 located in the supply gutter 4 and rotated together with the discharge screw shaft 6 in the direction of the arrow. A chaff removal passage 10 is provided in which a supply side 8 is connected to the upper wall 4a of the supply gutter 4 at a nearby position, and a discharge side 9 is connected to the side wall 4b of the feed gutter 4 at a position lower than the feed side 8. A large-diameter tank 11 is formed in the middle of the paddy removal passage 10, and a non-crushing type automatic moisture detector 12 is housed inside this tank 11. It is designed to automatically detect the moisture content of paddy that is continuously distributed. 13 is a rotary belt with a bucket belt 14 which is rotatably housed inside the elevator 2, and 15 is a hopper for the elevator.

Next, the operation of the present invention will be explained.

After paddy is continuously thrown into the loading hopper 15, when the rotating belt 13 and the carry-in gutter 3 are activated, the paddy is successively fed into the dryer 1 through the elevator 2 and the carry-in gutter 3. When a certain amount of paddy is filled therein, the operation of supplying paddy to the loading hopper 15 is stopped, and at the same time, the dryer 1 and the unloading screw shaft 6 are operated. In this way, the filled paddy is dried to some extent by being exposed to drying air as it sequentially flows vertically down inside the dryer 1, and then is continuously carried out into the supply gutter 4 by the carry-out screw shaft 6, and then After being transported to the elevator 2 side by a flip-up wheel 7 that rotates together with the unloading screw shaft 6, it is scooped up by a number of buckets 14 attached to a rotating belt 13, and returned to the upper part of the dryer 1 via the loading gutter 3. be swept away. Therefore, by repeating the above-mentioned circulation drying operation many times, the paddy can be finished and dried to a predetermined moisture content.

By the way, during the above-mentioned paddy circulation drying operation, the flip-up impeller 7 disposed in the supply gutter 4
is rotated together with the unloading screw shaft 6, so a part of the dried paddy continuously supplied from the unloading gutter 5 into the supply gutter 4 is forcibly thrown up by the lifting action of the rotating flip-up impeller 7. It is constantly distributed through the paddy removal passage 10 from the supply side 8 to the discharge side. Therefore, if you want to know the drying state during circulation drying work, by operating the non-crushing type automatic moisture detector 12, you can easily and continuously detect the moisture in the circulating paddy at any time. After the detection, the paddy is quickly returned to the supply gutter 4, passes through the elevator 2 and the carry-in gutter 3, and then returns to the dryer 1.
flowed back to. Therefore, the rice harvesting operation is simple and automatic, and the moisture detection operation can be accomplished quickly and easily, making it easy to obtain rice with an accurate moisture content.

In short, the present invention provides a supply gutter 4 on one side of the lower part of the elevator 2 to which the terminal end of the carry-out gutter 5 for carrying out the paddy from the dryer 1 is connected, and the supply gutter 4 at the connection position of the carry-out gutter 5 carries the paddy. A rotatable flip-up wheel 7 that can be jumped out and transported to the elevator 2 side is mounted on an axis, and a supply side 8 is connected to the upper wall 4a of the supply gutter 4 in the vicinity of the flip-up wheel 7 through an opening. In addition, a paddy removal passage 10 is provided in which the discharge side 9 is open-connected to the supply gutter 4 at a lower level than the supply side 8, and a non-crushing type automatic moisture detector 1 is provided in the paddy removal passage 10.
2 is installed, so that while the paddy dried by the dryer 1 is conveyed to the lower part of the elevator 2 by the flip-up wheel 7 via the carry-out gutter 5 and the supply gutter 4, a part of the paddy is immediately transferred to the flip-up blade. The paddy is forcibly taken out to the unloading passage 10 by the bouncing action of the car 7, and the moisture detection work of the paddy is quickly and easily carried out before the moisture content of the paddy changes due to the influence of the outside air, etc., and high quality dried paddy is obtained. Lifting machine 2 continuously lifts the paddy as much as possible.
The flip-up impeller 7, which is conveyed to the side, is used to easily collect paddy for moisture detection, simplifying the paddy collection device, and selecting the lowest moisture detection work position to improve the detection operation. In addition to making it easier to simplify and inspect, it also has the effect of efficiently achieving maintenance management.
