Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a grain moisture measuring device and can be used in grain dryers.

BACKGROUND ART Conventionally, in a moisture measuring device that measures moisture by receiving automatically fed grains and manually fed grains from an external input port, during automatic moisture measurement, grains fed from the external input port are This grain moisture measuring device detects the moisture content of manually fed grains and automatically fed grains at the same time.

Problems to be Solved by the Invention For example, in a grain moisture measuring device used in a grain dryer,
While the grains are being dried in this dryer, each part of the grain moisture measuring device is started by sending an electrical measurement signal, and while the grains are stored in the dryer and circulated repeatedly,... The grains are automatically fed from this dryer into this grain size measuring device, and the automatically fed grains are individually fed, for example, into the grain size measuring device.
Moisture in 32 grains was detected in the transmitted signal;
The average value of the detected grain moisture is calculated, and the average value of the 32 grains obtained by this calculation becomes the detected grain moisture at one time, and when this detected grain moisture becomes the same as the finishing target moisture, drying of the grain is stopped. Ru.

If grains are manually fed from the external input port 1 during moisture detection of the automatically fed grains, the manually fed grains and automatically fed grains mix and moisture is detected at the same time. It is done.

This may result in inaccurate moisture detection of manually fed grains, or the detected moisture data of manually fed grains may be entered into the detected moisture data of automatically fed grains. In some cases, accurate moisture detection of automatically fed grains could not be performed.

Means for Solving the Problems The present invention provides grains that are automatically fed and an external input port (one
), in which the automatic moisture measurement is controlled to be stopped for a predetermined period of time by supplying the grains from the external input port (1) during the automatic moisture measurement. The structure of the grain moisture measuring device is as follows.

Effect of the Invention While grains are being dried in a grain dryer, each part of the grain moisture measuring device is started by sending an electrical measurement signal, and while the grains are housed in the dryer and circulated repeatedly, the part of the grain being dried is The grains of
The dryer automatically feeds the grain moisture into the grain moisture measuring device, and the automatically fed grains are sent one grain at a time to 32
The moisture content of each grain is detected, the average value of these 32 grains is calculated, and the average value of the 32 grains obtained by this calculation becomes the detected grain moisture at one time. When the grain moisture measuring device detects it, the grain dryer is automatically stopped,
Drying of the grain is stopped.

If grains are manually fed from the external input port (1) during the moisture detection of the automatically fed grains, the moisture content of the automatically fed grains will increase over a predetermined period of time during the moisture detection of the manually fed grains. Detection is stopped and moisture detection is performed only for manually fed grains, and this detected moisture data for manually fed grains is not input into the detected moisture data for automatically fed grains and is processed separately. .

Effects of the Invention According to this invention, when grains are manually fed from the external input port (1) during moisture detection of the automatically fed grains, the moisture detection of the automatically fed grains is stopped and the manually fed grains are automatically fed. Since only moisture is detected, the moisture content of each supplied grain is detected instead of the moisture of mixed grains, and therefore the grain moisture of each supplied grain can be detected accurately.

The operation of the above embodiment will be explained below.

By operating the operating device (9), the dryer (2) is started, and at the same time, the burner (10) and grain moisture measuring device M (3) are started, and hot air is generated from this burner (10). The hot air passes through the drying chamber (7) and is sucked and exhausted by the exhaust fan (12), so that the grains stored in the storage chamber (5) are transported from the storage chamber (5) to the drying chamber (7). ), it is exposed to this hot air and dried, and is fed out to the lower part by the feeding valve (6), and is sent to the lower part through the grain collection gutter (8), the supply gutter (19), and into the grain raising machine (16). The packet conveyor (17) transports the packets to the upper part of the delivery tube (
The diffusion! (15) spread rI evenly into the storage chamber (5)! 1. When the grain moisture measuring device (3) detects the same grain moisture as the finishing target after being reduced and circulated dry, the operating device (9) automatically controls and automatically stops the dryer (2).

During this drying work, the grains that fall while being conveyed to the upper part of the packet conveyor (17) are received by the grain gutter (2o) and guided down by the grain gutter (20), and the grain moisture is measured. Device(
3) is supplied to the upper side of the grain transfer roll (28) and guide plate (31), and the grain moisture is measured. tal (3) is actuated by the transmission of electrical measurement signals transmitted at predetermined time intervals from the operating device (9), and the grain transfer roll (29)
The grains are fitted one by one into the spiral @ (33), and are transferred onto the detection rolls (35), (35) while being guided by the guide plate (31) along this spiral groove (33). Been supplied.

At the same time, the grains are compressed and crushed by the outer gratings of the detection rolls (35) and (35), and at the same time, the moisture content of the crushed grains is detected. The value is calculated by the control device (44) of the operating device fl (9), and the average value obtained by this calculation becomes the grain moisture detected once and is displayed on the display window.

During this automatic moisture detection, if the grain official funnel (43) is operated to an open state and grains are introduced from the outside, the grain official funnel (43) passes through the external input port (1) and the guide channel (40). The moisture of the externally supplied grains is detected by the detection rolls (35), (35), and during this externally supplied grain moisture detection, Automatically fed grains are not transferred and fed by the grain transfer roll (18), but only the manually fed grains have moisture detected, and this detected moisture is displayed on the display window.

By performing moisture detection separately for automatically fed grains and manually fed grains, the moisture content of each grain can be accurately detected.
