Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a forced feeding device for a grain dryer, and more particularly to a forced feeding device for a grain dryer in which a forced feeding device is provided below a grain guide plate in a drying chamber.

Prior Art In conventional grain dryers, grains (especially high-moisture wheat), garbage, straw, etc. accumulate in a part of the inclined corner of the tank, causing uneven circulation of the grains, resulting in uneven drying of the grains. There was a risk of mold and spoiled grains occurring.

It consists of a receiving gutter for receiving grains flowing down, and a feeding blade for rotating the grains on the receiving gutter along the receiving gutter surface to feed out the grains, and the upper end is placed near the upper end of the receiving gutter. Japanese Patent Publication No. 53-34310 discloses a grain dispensing device comprising a plate spring which is fixed, covered over the receiving gutter surface, and whose other end or upper surface is in contact with the rotational circumference of the dispensing blade. However, this device does not have a forced feeding device near a part of the inclined corner of the storage chamber, which is a tank, and the feeding blade is installed near the outlet of the drying chamber to prevent grains from flowing down. It dispensed a certain amount of.

In addition, both side walls of the dry material outlet are bent in the radial direction relative to the axis of the feed roll, and adjustment plates made of a soft elastic body are provided on the bent surfaces so as to be retractable in the radial direction of the feed roll axis. A grain feeding device is provided with a plurality of members for supporting and fixing a soft adjustment plate in the longitudinal direction of the feeding roll.
This is known as the Japanese Utility Model Publication No. 46-740, but this one also does not have a forced discharge device near a part of the inclined corner of the grain storage tank, which is a tank. Since the feed roll shaft is provided in the feed roller, the weight of the grain is directly applied to the entire feed roll blade, which may cause the feed roll shaft to become deflected.

Furthermore, it is provided with a pressure feeding machine connected to an air blower, and a hose connecting the pressure feeding machine and a recovery machine, the pressure feeding machine being provided below the upper open end of the pressure feeding machine, and the above-mentioned recovery machine being provided below the material inlet. A pumping and collecting device for lightweight materials is known as Japanese Utility Model Application Publication No. 53-67292, which is equipped with a plurality of rotating vanes over almost the entire internal cross section of the pumping machine and the collecting machine. A rotary blade, which is a forced-feeding device, is installed slightly above an inclined corner in a certain hopper, but the direction of rotation of the rotary blade is unknown, and the weight of the material acts directly on the entire rotary blade. Therefore, there was a risk that the rotating shaft would be bent.

Purpose of the invention The purpose of the invention is to eliminate the above-mentioned drawbacks.In order to prevent uneven grain circulation, a grain guide plate and a forced feeding device are provided in the tank, especially in a part of the inclined corner of the tank. This prevents high-moisture grains (especially high-moisture wheat), garbage, straw, etc. from accumulating in a part of the inclined corner of the tank, and prevents the generation of mold, degenerated grains, etc. due to accumulation. To provide a forced feeding device for a grain dryer that is simple in structure and can extend its life without adding the weight of grain to the grain dryer.

Structure of the Invention The forced feeding device for a grain dryer of the present invention includes a tank provided above the drying chamber, an umbrella-shaped grain guide plate provided near a part of the inclined corner in the side wall of the tank, and a The blade wheel has blades protruding between the guide plate and the guide plate, and has a rotation axis whose central axis is within the downward projected plane of the guide plate, and the tip of the blade covers a part of the inclined corner from above. This device has a configuration characterized by providing a forced feeding tool that rotates so as to move downward.

Example Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In FIG. 1, a grain dryer is indicated generally by the number 1.

The grain dryer 1 includes a tank 2 formed by a side wall 3, a drying chamber 4 formed by a wire mesh or a perforated plate, a hot air generator 5 consisting of a burner and a blower, a screw conveyor 7, etc. to collect grains, and a grain lifting machine. At step 9, remove the transfer device that circulates the grain in tank 2.

A drying chamber 4 is arranged below the tank 2, and an umbrella-shaped grain guide plate 8 is provided particularly near a part of the lower inclined corner of the tank 2.

A feeding device 6 equipped with blades is provided below the drying chamber 4 to adjust the feeding of grains within the drying chamber 4.

A forced-feeding device in a grain dryer according to the present invention is indicated generally by the number 10 in FIG. It is especially provided under the guide plate 8.

A forced feeding device 10 in a grain dryer is arranged on the left and right sides of a tank 2, and has a plurality of blades 12 on a rotating shaft 11.
The blade 12 protrudes between the side wall 3 of the tank 2 and the umbrella-shaped guide plate 8 slightly above a part of the corner of the slope,
The center axis of the rotating shaft 11 is located within the downward projection plane of the guide plate 8.

A sprocket wheel 13 is attached to the rotating shaft 11, and is rotated by a motor 15 via a chain 14 in the direction of the arrow in the figure, so that the tips of the blades 12 move along a portion of the inclined corner from above to below.

Next, the operation of the embodiment of the present invention will be explained.
Drive the grain lifting machine 9, screw conveyor 7 and motor 15 to operate the forced feeding device 10 in the grain dryer,
Grain is circulated within a grain dryer 1.

Furthermore, the hot air generator 5 is operated to pass the hot air through the wire gauze to dry the grains falling inside the drying chamber 4.

The grain near a part of the sloping corner of the tank 2 is arranged so that the tip of the blade 12 protruding between the side wall 3 of the tank 2 and the umbrella-shaped guide plate 8 moves the part of the slanted corner from above to below. Since the grain rotates while moving, it is sent to the drying chamber 4 below without being stagnated, and since the rotating shaft 11 is within the downward projection plane of the guide plate 8, it is not directly affected by the weight of the grain.

It should be noted that the forced feed device 10 in the grain dryer can operate continuously or intermittently only at desired times.

Effects of the Invention Since the present invention has the above-described configuration, the tip of the blade protruding between the side wall of the tank and the umbrella-shaped guide plate rotates so as to move from the upper part to the lower part of the inclined corner. ,
Grain does not accumulate near a part of the inclined corner of the tank, and the grain is reliably sent to the drying chamber below and circulated smoothly, eliminating uneven drying and preventing mold and spoiled grain from accumulating. Since the rotary axis of the blade is within the downward projection plane of the guide plate, the weight of the grain is not directly applied to the entire forced feeding device, making it possible to extend the life of the forced feeding device. Moreover, it is extremely simple. The above functions can be distantly related with a configuration like this.
