Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a grain milling device provided with an air blower for removing residue in a grain milling chamber.

The grain milling trochanter, which is supported on a shaft in the grain milling chamber, is usually located below the grain supply port, and includes a radio section for transferring the supplied grains in the grain shredding direction, and a radio section for receiving the grains. Since it consists of a grain milling section that applies grinding and grinding for grain milling, the grains that are continuously supplied during the grain milling process are transferred to the grain milling section by the transfer force of the helical section, and then to the grain threshing port. The grains that have passed through the pickle and radio section are being pushed out by the grains that are successively pumped, but at the end of the grain milling process, the grains in the radio section are being transferred. Since the grain polishing section itself does not have a transporting force, grains tend to remain between the grain polishing section and the grain threshing section.

The present invention takes the following technical measures to solve this drawback. That is, the grain milling trochanter is rotatably mounted on the shaft (3), and the grains supplied from the grain supply port (C) side are transferred to the grain discharging port (7).
The inside of the grain milling chamber (1) on the outer periphery of the grain milling trochanter is directed toward the grain discharging port (7) side. The configuration includes a blowhole (2) that can blow air.

This invention has the following technical effects due to such a configuration. That is, when grains are supplied from the grain supply port (c), the grains are milled while being transferred inside the grain milling chamber (1) toward the grain discharging port (7). At the end of the process, or just before that, if the air is blown from the blower port (2), the grains, attached bran, etc. remaining in the grain milling chamber (1) on the outer periphery of the grain milling trochanter will be removed. The grains are swept toward the threshing port (7) by the wind pressure, and the jet port (2) is opened only when there are few grains in the grain milling room (1). Since the remaining grains, etc. can be blown out, the blowing effect is good, and during grain milling, the blow-off port (2) can be closed to reduce the blow-up from the grain supply port (c). can.

In addition, in the illustrated example, the grain milling device with and has a horizontal shaft (3
) An input pulley (4) is provided at one end of the input pulley (4), and the shaft (3) is inserted from the bearing portion (5) close to the input pulley (4) toward the grain discharging port (7). from the input pulley (4) side bearing part (5) to the air pressure chamber (6) and the grain milling chamber (1).
), the grain threshing port (7), and the resistance plate (8), the terminal end is provided with a bearing part (9) that supports the shaft (3), and the input pulley (4) side bearing part (5) and The outer periphery of the grain threshing port (7) is supported on the machine frame 01. Note that the shaft (3) is provided with a cutout plane part (11) parallel to the axis extending from the vicinity of the bearing part (5) to the terminal end of the bearing part (9). The pressure chamber (6) is connected to a blowing device disposed below through a blowing pipe 03, and this blowing device is interlocked with a belt from a pulley Oa. In the partition wall 04) between the pressure chamber (6) and the grain milling chamber (1), air blowing ports (2) communicating with the grain milling chamber (1) are provided equidistantly around the axis (3), The disc valve α in contact with the air pressure chamber (6) side of this partition wall 04) has a ventilation port 0O in the same phase as the jet port (2), and is elastically moved toward the partition wall 04) side by a nupling (17). It is energized, is rotatably provided around the shaft (3), and has a lever α8) portion that protrudes through the earthen wall of the air pressure chamber (6). Note that the through hole of the lever 08)
) is a long hole θ9 that can rotate around the shaft (3) within a range that closes the ventilation hole 0, and the inner surface of the air pressure chamber (6) is sealed with a sealing material.

In the grain milling room (1), in the vicinity of the partition wall 04), there is a feed roll ridge portion with a spiral outer periphery of a grain milling trochanter, and a resistance roll 0 having a band-like protrusion (c) along the axial direction on the outer periphery. ]) parts are connected to each other with a shaft, and the inner surface of each roll is provided with a space part (a) on the inside leaving a shaft attachment part at both ends, and furthermore, the center part corresponds to the flat part 0]) of the shaft. It has a driving protrusion (c) in contact with it. In addition, between the band-like protrusions (C) of the resistance roll (21), there are slit holes (C) that communicate with the space (A) from the outer periphery.

A grain supply port (C) with an opening/closing plate (C) is provided above the feed roll (A) on the partition wall 04) side of the grain milling room (1), and a grain tank (H) is provided in the second part of the port (C). ) will be established. In addition, on the outer periphery of the resistance roll 01) part of the grain milling room (1), a bran removal screen (G) is provided with a mesh frame (A), and at the end thereof, from the inner periphery of the bran removal screen (G), A so-called throttling hole (7) which gradually becomes smaller is provided, and a resistance plate (8) is provided on the outside thereof so as to be rotatable on an upper support shaft, and the upper portion is arranged in the direction of the axis (3). Along the armrest, there is a sliding device (01) attached to the armrest.

Oa is a grain flow guide trough.

When the input pulley (4) is driven, the grain milling trochanter is rotated by the shaft (3), and the grains in the grain tank (c) flow down into the grain milling room (1) by opening the opening/closing plate @. , the grain is sent to the resistance roll Q]) by the feed roll (A) part, and is passed through the threshing port (7).
The grain is polished while being subjected to resistance from the resistance plate (8) and gradually flows out through the grain discharge port (7) and into the downstream guide trough 0 pit. On the other hand, the blower conducted from the blower IJQ2 flows through the blower pipe to the pressure chamber (6), and further flows to the flat part of the shaft (3).
) from the feed roll (A) to the resistance roll (21
), air is blown through the slit holes (c) of the resistance roll ■υ, and the bran generated while cooling the grains being polished is removed from the bran removal net (7). Room (1) Take 4 outside. During grain milling, the air outlet (2) provided in the partition wall 04 of the air pressure chamber (6) and the grain milling room (1) is closed by rotating the disc valve 0$. The final stage of grain polishing is in the open state. Pressure chamber (
The pressure air in 6) is blown from the opened blowhole (2) toward the grain milling chamber (1) on the outer periphery of the grain milling trochanter along the axial direction. The residue in (1) is moved from the bran removal screen (1) and the grain threshing port (7) to the grain milling room (1) by the pressure air.
