Description

[Detailed description of the invention] Industrial application field The present invention scrapes out the grains carried into the carry-in gutter, and uses the scraping and discharging action of the conveyance screw and the falling filling action from the drop opening in the longitudinal direction from one side of the carry-in gutter. A grain dryer that is capable of filling an even amount of grain into a dryer main body according to the specified schedule, and accurately detecting when the grain is filled into the dryer main body in a full state and stopping the grain loading operation. The present invention relates to a full capacity sensing device in a machine.

Conventional technology Conventionally, a carry-in gutter with a shaft that houses a rotatable screw conveyor was arranged horizontally in the upper part of the dryer main body, and a predetermined amount of grain was delivered to three locations by the rotation of the screw conveyor. Prior to the filing of this application, there was a device for monitoring the loading amount of grain in a grain dryer, which allows the grain to be dropped into the dryer main body from a drop opening and notifies the user by operating a switch when the dryer main body is filled with grain to its full capacity. For example, it is known as described in Japanese Utility Model Application Publication No. 52-163549, and its contents will be explained with reference to FIG. That is, the upper part of the dryer body 1 is surrounded by a surrounding wall, and a rotatable screw conveyor 3 is housed inside, and the bottom wall 4 has three drop ports 5a, 5b, 5c. A carry-in gutter 2, which is opened at sequential intervals, is installed horizontally, and a switch 6, which is operated by the pressure of the grain that is dropped, is installed at the drop port 5c at the end of the conveyance, so that the grain can be dried. The operator is notified by operating the switch 6 that the machine body 1 is fully filled.

Problems that the invention attempts to solve By the way, in the conventional filling amount monitoring device,
Since the switch that notifies you when the dryer is fully filled with grain is located at the dropping port where the grain is discharged, the switch may be triggered by straw, etc. wrapped around the screw conveyor during the conveyance process. There are many accidents where the switch malfunctions due to being pressed, and there are disadvantages such as the switch being quickly worn out or deformed due to the contact with the grain pressure constantly discharged from the drop port, as well as the accumulation of grain. A problem arose in that three piles were formed in the same number as the number of drop openings, making it impossible to arrange the grain in a substantially level condition.

Means for Solving the Problems The present invention is intended to solve the above-mentioned problems, and its contents will be explained below using FIGS. 1 to 3, which correspond to embodiments.

That is, in the upper position in the dryer main body 101,
A horizontally long carry-in gutter 102 with an open bottom and an open top 104 is arranged horizontally. Of the left and right side walls 103, 103' of the carry-in gutter 102, one side wall 103 for discharging grains is formed so that its height is gradually lowered from the supply side to the conveyance side, and the scraping conveyance screw 104 can be freely rotated inside. It is stored on a rack. Bottom wall 106 on the conveyance end side of the carry-in gutter 102
A drop port 107 is opened at the bottom. Further, on the outer surface of the side wall 103' near the drop port 107, there is a full level detection switch 10 for detecting the full level state.
8 is installed.

Operation Now, the scraping conveyance screw 105 is rotated by an appropriate power, and at the same time, the grain is carried into the supply side of the carry-in gutter 102. During the conveyance process, the grains are scraped and discharged from one side wall 10 by the scraping and discharging action of the rotating scraping and conveying screw 105.
3, 103, from the open upper surface 104 side, the grains are dropped and filled into the dryer main body 101 in equal amounts in a shower-like manner, and the grains that are transported without being scraped out from the left and right side walls 103, 103 are deposited on the bottom wall 106 at the end of transport. The liquid is dropped and filled into the dryer main body 101 through the provided drop port 107. Therefore, even if a large amount of grain is carried into the supply side of the carry-in gutter 102, the grain will be scraped out by the conveyance screw 105 because the height of the side wall 103 on the discharge side is formed to be gradually lower toward the discharge side than the supply side. Due to the scraping and discharging action caused by the rotation, approximately equal amounts of grain can be sequentially dropped and filled into the dryer main body 101 along the longitudinal direction of the carry-in gutter 102. As described above, when the grain approaches the full state in the dryer main body 101, the full state detection switch 108 is activated by the contact with the filled grain, and it is possible to sense that the full state has been reached. The work of carrying grain into the gutter 102 may be stopped.

Note that the full capacity detection switch 108 is connected to the drop port 10.
Since it is attached to the outer surface of the side wall 103' near position 7, it can be used for long periods of time without malfunction due to entanglement with straw or the like during grain filling work, or wear and deformation due to contact with grain. can be carried out.

Embodiment An embodiment of the full capacity sensing device for a grain dryer according to the present invention will be described with reference to the accompanying drawings. In the drawings, reference numeral 101 denotes a dryer main body formed in the shape of a rectangular rectangular tube as a whole, and a horizontally long bottomed carry-in gutter 102 with an open upper surface 104 is arranged horizontally at an upper position in the dryer main body 101.

The height of the side wall 103 on the inner grain discharge side of 03' is made gradually lower from the supply side to the conveyance side, and a scraper conveyance screw 105 is rotatably housed therein. A drop port 107 is formed in the bottom wall 106 of the carry-in gutter 102 on the transport terminal side. Reference numeral 108 denotes a full amount detection switch attached to the outer surface of the side wall 103 near the drop port 107.

Therefore, according to the device of the present invention, the carry-in gutter 10
Even when a large amount of grain is brought into the supply side of the conveyance gutter 102, the grain is scraped out and discharged by the rotation of the conveyance screw 105, and by the falling action from the drop opening 107, the grain is kept approximately flat over the entire length of the inlet gutter 102. The dryer main body 10 can be filled with grains into the dryer main body 101 in a shower-like manner.
