Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a device for transferring grains one by one to a moisture meter for a grain dryer, an optical discriminating device, and the like.

[Prior Art and its Problems] When treating grains, it is necessary to transfer the grains one by one in order to judge the properties of these grains. For example,
Grain, brown rice from a hulling machine, split grain of rice from a rice milling machine,
In order to detect defective grains, it is necessary to send them one by one to an optical discriminating device. Also, when measuring the moisture content of grains, if the properties of each grain are different, it will be a great obstacle to know the moisture content of the whole grain. It is necessary to measure and statistically know the total water content.

For example, in a moisture meter in which a sample in a grain dryer is taken out and measured one grain at a time with a measuring roll, a transfer device is required to take grain into the measuring roll one grain at a time. Various types of transfer devices are known.
Explaining the typical structure, first of all, the actual construction 58-7
No. 1018 discloses a rotary table type structure.
In this structure, the rotary plate formed with a plurality of dents each having a size that allows the measured grains to enter one by one along the outer periphery is inclined, and the measured grain is rotated by rotating the rotary plate. The grains are transferred one by one to the higher side of the rotating plate, and the grains transferred near the upper part of the rotating plate are discharged to the discharge passage and sent to the inspection roll. Further, Japanese Patent Application Laid-Open No. 62-55544 discloses a structure using a roll with a spiral groove, and by rotating the roll while bringing the flat plate into contact with the roll, the grain between the spiral groove and the flat plate is Grains are sandwiched and transferred one by one toward the discharge port.

In all of these conventional grain transfer device structures, it is necessary to manually sample the grains in the dryer and transfer them to the transfer device, or to provide a device for incorporating a sample by providing a bypass passage in the dryer. It is necessary to devise various measures for the structure of the bypass passage. Furthermore, it is necessary to consider the removal of the residual sample when the moisture detection is stopped.

[Object of the Invention] An object of the present invention is to provide a grain transfer device having a simple structure and easy to handle.

[Constitution of the Invention] In order to achieve this object, the present invention has a pair of rolls, which are rotatably supported in a state in which they are engaged with each other and which are rotatably supported with each other, are formed with outer threads opposite to each other. A drive mechanism that rotates the threads in opposite directions so that the threads move away from each other at the top, and a discharge mechanism that discharges the grains that have moved between the threads at the top of the meshing portion of the roll one by one. And a grain transfer device including an outlet.

[Operation and Effect of Device] According to such a configuration, as the pair of rolls rotate, the grains move one by one in the meshing portion where the roll surfaces move in the directions away from each other. The particles are transferred from one end to the other end and finally taken out one by one from the discharge port. Therefore, the grains can be taken out one by one by inserting only the paired rolls into the grain. If such a transfer device is incorporated into a measuring device such as a moisture meter or a detecting device, it is easy to handle and has a simple structure, and a measuring device or a detecting device with a transfer device that can reliably take out grains one by one is obtained. be able to.

[Embodiment] An embodiment of the present invention will be described below with reference to the accompanying drawings.

First, referring to FIGS. 1 to 3, a grain transfer device 10 according to an embodiment of the present invention shown in FIG.
14 are included. These rolls 12 and 14 are formed with outer threads in the form of a right-hand thread and a left-hand thread, respectively, and are rotatably attached to the support plate 16 so that these outer threads engage with each other. Shafts 18 and 2 of rolls 12 and 14
Reference numeral 0 extends from the support plate 16 through the bearing plate 22, and gears 24 and 26 are fixed to the respective ends. These gears 24, 26 are in mesh with each other, thus
The rolls 12 and 14 can rotate synchronously. In addition,
Although not shown, one of the gears is engaged with a drive gear, and the motors (not shown) can rotate the roll gears 24 and 26 synchronously via the drive gear. In this case, the rolls 12 and 14 must be rotated in opposite directions so that the threads move away from each other at the top of the mating portion, as shown in FIG.
Hereinafter, this rotation of the roll will be referred to as external rotation.

Openings 28 are formed in the support plate 16 at positions corresponding to the upper portions of the meshing portions of the rolls 12 and 14.

In such an arrangement, the roll 1 as shown in FIG.
When 2, 2 and 14 are rotated outward, the grains 30 move one by one from the left as seen in Fig. 1 and Fig. 2 along the screw thread in the upper part of the roll meshing part to the right direction and finally support. It is discharged through an opening 28 in the plate 16. Of course, roll 1
Even if there are grains around 2,14, the grains are surely transferred at the upper part of the meshing part of the roll,
The surrounding kernels are attracted to it and move towards the opening 28,
The particles are discharged one by one from the opening 28.

Such a grain transfer device can be incorporated in the moisture meter 32, for example, as shown in FIG. In that case,
The grain can be taken into the moisture meter 32 from the grain dryer through the side wall only by inserting only the grain transfer device portion 10 attached to the moisture meter 32 into the outlet provided on the grain dryer side wall 34. Although various configurations are conceivable as the moisture meter, in the drawing, an electrode roll system having a pair of roll-shaped electrodes (E) arranged side by side is adopted. The display unit of the main body of the moisture meter is not particularly shown.

Since the rolls 12 and 14 are rotated outside, the sample is not caught in the rolls and jammed. Furthermore, when performing intermittent measurement, there is almost no residue during the previous measurement, and most of the sample on the upper part of the roll meshing part is removed to the outside by the outer rotation of the roll, so a new sample without drying delay is constantly supplied. To be done.

Although the present invention has been described in detail in the form of an embodiment, the present invention is not limited to the form of the above embodiment, but can be variously modified within a range limited by the scope of claims for utility model registration. .

That is, in the above-described embodiment, the grain transfer device has been described as being used with the moisture meter, but it can be used with a grain determination device other than the moisture meter, for example, an optical measuring device of a split grain determination device.
