Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a fried apparatus used in a thresher or the like.

[Prior art]

Conventionally, as this type of grain conveying device, a full-fledged Shokai 53-1004
As disclosed in Japanese Unexamined Patent Publication No. 68, the end of the shaft of the transfer spiral for horizontal feed and the vertical transmission shaft are interlockingly connected via a bevel gear, and the pulley fixed to the lower end of the vertical transmission shaft and the vertical feed shaft are connected. The belt is wound around a pulley fixed to the shaft of the fried helix, and the rotational power of the transfer spiral for the transverse feed is configured to be transmitted to the fried helix for the vertical feed through the vertical transmission shaft and the belt. There is. Further, as disclosed in Japanese Patent Application Laid-Open No. 60-248509, the take-up blade at the end of the transfer spiral for lateral feeding faces the outer peripheral rotation range of the fried helix when viewed in the axial direction of the fried helix. is not.

[Problems to be solved by the device]

However, in the former conventional device, not only is the structure very complicated, but since the end of the transverse feed transport spiral and the lower end of the vertical feed helix cannot be wrapped, It was difficult to smoothly transfer the grain to the fried helix, and there was a problem that the grain was stagnated and jammed at the transfer portion. Further, in the latter conventional device, since the grains flipped up by the take-up blade are not directly handed over to the outer peripheral rotation area of the lifting helix, there is a problem that a large amount of back flow of the grains occurs.

The present invention aims to solve these problems,
The following technical measures were taken.

[Means for Solving the Problems]

That is, the technical means according to the present invention are: the terminal end of the shaft 14 of the transfer spiral 1 for transferring the grain to one side in the lateral direction, and the lifted spiral for taking over and transferring the transferred grain. It is composed of an elbow-shaped connecting tube for interlockingly connecting the lower end of the shaft 24 of the second shaft 2 through a pair of bevel gears 25, and for internally mounting the end part of the transfer spiral 1 and the start part of the fried helix 2 inside. The bearing 17 is provided with a transfer passage 19 for transferring and transferring the grains upward from the end portion of the transfer spiral 1, and the upper wall surface of the bearing 17 on the side of the transfer passage 19 of the bearing 17 rises to an inclined surface 17a. In addition, at the end of the transfer spiral 1, there is continuously provided a take-up blade 3 which has a diameter larger than the outer diameter of the spiral 1b on the transfer start end side of the transfer spiral and which jumps up the grain toward the take-up passage 19. In addition, the take-up blade 3 faces the rotation range of the outer circumference of the fried helix 2 when viewed from the axial direction of the fried helix 2. The one in which the features.

[Action]

By interlocking and connecting the shaft of the transfer spiral and the shaft of the fried food spiral via a pair of bevel gears, the rotational power of the shaft of the transfer spiral can be directly transmitted to the shaft of the fried food spiral. Parts such as transmission shaft, pulley, belt, and space for them are not required.

Also, because the upper wall surface on the takeover passage side is a rising slope,
The grain sent by the transfer spiral is flipped up by the takeover blade at the end, but it is sent up in the direction along the ascending slope, and the direction is not changed at a substantially right angle. Therefore, the jam is not clogged, and the grains are smoothly handed over to the fried helix side.

Since the diameter of the take-up blade is made larger than the diameter of the spiral on the transport start end side of the transfer spiral, the peripheral speed at the peripheral end portion becomes faster, and the grain can be rebounded more effectively.

In particular, since the takeover blade faces the outer peripheral rotation range of the fried helix, the grains are reliably splashed up and supplied into the rotary feed fried range of the fried helix.

[Effect of device]

Therefore, according to the present invention, various parts of the grain lifting device are omitted, the structure is simplified, and the device is compact and lightweight.

Moreover, it is possible to smoothly and reliably perform the transfer from the transfer spiral for horizontal feed to the lift spiral for vertical feed, without causing stagnation or clogging, even though the grain transfer passage is narrowed due to the presence of the bevel gear. it can.

In particular, since the grains bounced up by the take-up blade are continuously taken up and supplied also to the outer peripheral rotation area of the hoisting helix, backflow is extremely small, and the succeeding take-up frying efficiency can be further improved.
