Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is a suction-type circulation type grain dryer that can easily provide grains for moisture measurement without impairing the drying function during operation.
Moreover, the present invention relates to an improvement of a grain sample extracting device for moisture measurement in a grain dryer that can be easily taken out.

[Prior Art] Conventionally, in a suction-type circulation type paddy dryer, a lifter attached to one side of the dryer main body is used to take out paddy for moisture measurement without impairing the drying function during operation. A box with an open upper part is attached to surround the paddy removal port and the paddy return port at an appropriate position on the side surface, and the box has an open top with a paddy accommodating portion at the end. A device for taking out a sample of paddy for measuring moisture in a paddy dryer in which a paddy take-out container is inserted and removed freely is described in, for example, Japanese Utility Model Publication 60-15117.

[Problems to be solved by the invention] By the way, since the conventional sample extracting device for this type of moisture measuring paddy is directly provided on the lifting side of the elevator, the elevator is inevitably made separately. Perhaps, the structure is complicated and expensive, and the sample take-out device is provided at a high position, so that there is a problem that the work of taking out the sample paddy is inconvenient.

The present invention has been made in view of the above problems of the prior art, and its purpose is to provide a sample container on a shutter plate of a tension hopper attached to a lower side surface of an elevator. So, even if the elevator and the stake-in hopper are ready-made products, it may be possible to take out the grain for the sample, or the structure can be made very simple and the entire device can be provided at low cost. In particular, the present invention aims to provide a grain sample extracting device for moisture measurement in a grain dryer in which the sample extracting position is made as low as possible to facilitate the collecting work and prevent the shutter plate from coming off.

[Means for Solving the Problems] In order to achieve the above object, a grain sampler for moisture measurement in a grain dryer according to the present invention is provided with a hopper installed in a feed window opened on a lower feeding side of an elevator. The supply port is open-connected, and a shutter plate that can be moved up and down is provided between the elevator and the tension hopper to open and close the supply cylinder, and the lower part is opened to the shutter plate arranged in the supply cylinder. On the front surface of the sample taking-out window part formed by the above, a sample container box which opens the side matching the sample taking-out window part and the upper side is detachably mounted, and the sample container box is provided with a feed port of a stretch hopper. Also, the sample container for taking out and storing the sample paddy in the elevator is inserted and removed through the sample taking-out window portion of the shutter plate.

[Operation] Now, the grains to be dried are continuously supplied into the feeding hopper, and if the shutter plate is pulled up until the sample box collides with the feeding cylinder, the elevators and the feeding hoppers in operation will keep the feeding cylinder. The grains in the expansion hopper are continuously supplied to the inside of the elevator through the elevator, and then the elevator is extended into the dryer main body by the elevator to finish and dry to a predetermined water content by several circulation actions.

By the way, in the drying operation as described above, when the sample grain is to be taken out in order to measure the water content of the dried grain, first, the shutter plate is lowered, the supply port is closed, and then, as shown in FIG. As shown, the sample container is inserted into the sample container box so that the open side of the sample container matches the sample take-out window opened at the bottom of the shutter plate.

By the way, some grains dropped in the process of being lifted by the elevator or some grains jumped up at the time of being lifted are stored in the sample container through the sample take-out window. Therefore, if the sample container is pulled out from the sample container box, the grain for moisture measurement can be easily taken out. Then, since the sample container is inserted into the sample container box attached to the lower part of the shutter plate, the work of inserting or pulling out the sample container can be quickly achieved with labor saving.

Incidentally, when the sample grain is not taken out, the sample container is reversed from the above, that is, if the sample container is inserted into the sample container box with the open side facing outward,
The lift can be kept sealed. In addition, since the sample take-out window is provided on the side of pumping, even if the sample container is pulled out from the sample container box at the time of grain sampling, the internal pressure of the dryer main body does not change and the drying performance is not degraded. It will never come.

[Examples] Examples will be described with reference to the drawings.

In FIGS. 1 to 4, reference numeral 1 denotes an elevator attached to one side of an appropriate suction type circulation type grain dryer (not shown), which is supplied to a feeding side surface 2 below the elevator 1. The window 3 is opened, and the feed window 3 is opened and connected to the feed port 6 of the tension hopper 4 mounted on the elevator 1 through an appropriate support member 5, and the dried grain is fed into the tension hopper 4. Through the supply port 6 and the supply window 3 into the elevator 1.

Reference numeral 7 denotes a shutter plate that is inserted into the opening 8 of the support member 5 and that can be opened and closed along the insertion opening 8 to open and close the supply opening 6.
A sample take-out window 9 is opened at the bottom of the shutter plate 7. On the shutter plate 7 on the front side of the sample take-out window 9, a sample container box 10 having both the side facing the sump take-out window 9 and the upper surface opened 11, 12 is detachably mounted. Reference numeral 13 is a sample container that is inserted into the sample container box 10 so as to be freely inserted and removed from the upper surface open side 12, and the sample container 13 has a grain container 14 at its lower end as shown in FIG. It has a box shape with an open top.

Needless to say, inside the elevator 1, bucket belts having buckets mounted on the peripheral surface at equal intervals are accommodated in a suspended manner so as to be rotatable in the arrow direction.

[Advantages of the Invention] Since the present invention is configured as described above, it has the following effects.

A sample take-out window is opened in the shutter plate that opens and closes the supply cylinder of the stake-in hopper, and this is equipped with a sample container box in which the sample container can be inserted and removed freely in front of the sample take-out window. In the grain dryer, while keeping the inside of the dryer securely sealed, sampling of grains can be performed easily at the low position of the elevator with labor saving and reliably without scattering around and Since the outlet is installed through the feed port of the stake-in hopper provided on the elevator and the outlet window of the shutter plate, the installation work can be performed easily, and it can be installed on existing elevators as well as new elevators. It can be easily dealt with, and since the sample container box is attached to the shutter plate, the shutter plate can be used when supplying grains. It may be possible that the sample container box will not be unintentionally pulled out by being caught by the supply cylinder when the lifting supply port is opened, or the sampling port is closed with the shutter plate during sampling. In addition to the fact that the contained grains are not sucked out from the sample container due to the negative pressure action, the structure can be simplified and the product can be provided at low cost.
