JP2511096Y2 - Residual grain discharging device in grain dryer - Google Patents

Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is capable of reliably discharging the grain remaining in the feeding unit at the end of drying by the scraping operation of the elastic scraping body rotating with the paying roll. Remaining grain discharging device in a machine.

[Prior Art] Conventionally, a device for providing a feeding roll in a feeding part of a grain dryer and discharging grain from the feeding part is disclosed in Japanese Utility Model Publication No. 2-61832 or Japanese Utility Model Publication No. 2-61832, which was published before the present application. 6
The one described in Japanese Patent No. 1833 is known.

In this conventional apparatus, the pay-out roll is provided with an elastic plate scraper that projects outward from the pay-out blade.

[Problems to be Solved by the Invention] By the way, since the scraper in the above-mentioned conventional device is composed of an elastic plate having a substantially flat plate shape, the scraper is provided along the inner surface of the gutter as the payout roll rotates. While deforming in the direction opposite to the rotating direction and repeating sliding contact,
When the material is fatigued and cannot be restored, it does not hinder the discharge of the grain remaining in the gutter, and the elastic force of the scraper decreases, or when the scraper moves slightly upward from the inner surface of the gutter. It was found that the grain was crushed and scraped between the inner surface of the gutter and the scraper, which caused crushing damage to the grain.

The present invention has been made in view of the above problems of the prior art, and its object is to attach elastic scrapers to the left and right sides of the mounting plate and the center of the elastic scrapers. Formed integrally so that the base end side of the leftover grain scraping blade protruding outward from the blade is connected,
The left and right mounting plates are fixedly attached to a pair of opposing feeding blades, so that the elastic elasticity of the mounting portion of the elastic scraping body is increased to prevent material fatigue due to repeated deformation and the residual grain scraping blade. To improve the resilience of the grain, and to provide a good grain scraping operation for a long period of time, and to reliably discharge the residual grain without causing crushing damage. To do.

[Means for Solving the Problems] In order to achieve the above object, the residual grain discharging device in the grain dryer according to the present invention is provided with a plurality of feeding blades in the feeding portion provided at the terminal side of the drying passage. Arranged feeding rolls radially mounted on the rotating shaft at intervals, between the pair of facing feeding blades, mounting plates located on both left and right sides, and at the center, projecting outward from the feeding blades. The elastic scraping body is integrally formed so as to be connected to the base end side of the remaining grain scraping blade, and the elastic scraping body is mounted by fixing the left and right mounting plates to the inner surfaces of the pair of feeding blades. It is sandwiched between plates and attached.

[Operation] At the start of drying, after the grain is filled in the drying passage and the feeding portion, the drying air is circulated across the drying passage and at the same time, the feeding roll is rotated in the arrow direction at an appropriate peripheral speed.

By doing so, the grains filled in the drying passage and the feeding portion due to the rotation operation of the feeding roll are discharged from the feeding portion by an equal amount by the plurality of feeding blades, and then returned to the drying passage again to be dried. The circulation drying operation of drying with wind is repeated.

By the way, at the time of the grain feeding operation as described above, between the pair of facing feeding blades, there is a mounting plate located on both the left and right sides and a center of the remaining grain scraping blades protruding outward from the feeding blades. Since the elastic scraping body integrally formed so as to be connected to the base end side is arranged, the left and right mounting plates are sandwiched and mounted by the mounting plates fixed to the inner surfaces of the pair of feeding blades. The resilience of the elastic scraping blade of the elastic scraping body does not decrease for a long period of time, and the residual grain in the feeding portion is scraped out smoothly by the residual grain scraping blade without causing crushing damage.

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

In FIGS. 1 to 3, reference numeral 1 denotes a drying passage vertically provided between a hot air chamber 2 and an exhaust air chamber 3 each having a horizontally long shape. The drying passage 1 is obliquely downward at the end side of the drying passage 1. A feeding portion 6 constituted by an inclined upper grain plate 4 and an inclined lower grain plate 5 is provided in a communicating manner. Inside the feeding unit 6, a horizontally long feeding roll 7 is installed so as to be intermittently or continuously rotated at a peripheral speed of approximately 12 cm / sec. The feeding roll 7 is
A plurality of sheets having a bent portion 9'having a laterally long shape on a rotary shaft 8 erected for intermittent or continuous rotation over the left and right side walls 15, 15 and having a tip end side bent in a counter-rotational direction. The feeding blades 9 ... Are radially welded at equal intervals, and of the plurality of feeding blades 9, a pair of feeding blades 9 and 9 facing each other have a horizontally long shape. The mounting plates 10 and 10 are integrally welded. 11 is a horizontally elongated elastic scraping body disposed between the pair of feeding blades 9 and 9, and the elastic scraping body 11 is entirely formed in a horizontally elongated shape by an elastic material such as rubber, In addition, the mounting plates 12, 12 located on both the left and right sides are integrally formed with the base end side of the remaining grain scraping blade 13 located at the center and projecting outward from the feeding blade 9. It is a thing.

Then, the left and right mounting plates 12 and 12 are brought into contact with the pair of mounting plates 10 and 10, and then the tip sides 14 and 14 of the mounting plates 10 and 10 are bent toward each other inwardly to firmly, and It is attached so that it can be easily removed and replaced.

[Effects of the Invention] The present invention is configured as described above, and has the following effects.

The elastic scraping body is integrally formed so that the mounting plates located on the left and right sides and the base end side of the residual grain scraping blade located at the center and projecting outward from the feeding blade are connected to each other. Since the mounting plate of is fixedly attached to the pair of feeding blades facing each other, the elasticity of the mounting portion of the elastic scraping body is increased to prevent material fatigue due to repeated deformation, and the resilience of the residual grain scraping blade is improved. As a result, a good grain scraping operation can be maintained for a long period of time, and residual grain can be reliably discharged without causing crushing damage.
