JPH0728830Y2 - Second product reduction section of threshing equipment - Google Patents

Description

[Detailed Description of the Invention] [Industrial field of application] The present invention has a processing chamber connected to the end of a No. 2 screw for transferring the No. 2 product from a sorting unit to one side, and processing the same. A processing rotator in which processing teeth are implanted is arranged in the chamber, and a part of a peripheral wall located along the outer periphery of the processing rotator is detachably configured in the processing case forming the processing chamber. The present invention relates to a second reducing part of a threshing device in which a tooth is attached to a removable peripheral wall portion so as to overlap with a tooth to be treated of the processing rotator when viewed in the axial direction.

[Conventional technology]

Conventionally, the second material reducing unit of this type of threshing device is configured as a single removable lid having a peripheral wall portion to which teeth are attached. By removing the peripheral wall portion, the inside of the processing case and the processing rotary member are removed. While the maintenance / inspection port is opened, the teeth are taken out of the processing case to facilitate maintenance / inspection.

[Problems to be solved by the device]

However, in the case of the above-described second-piece reducing unit, since the maintenance / inspection port is closed by the mounting of the peripheral wall portion, the tooth receiving member attached to the peripheral wall portion and the processing rotary member are planted. It is possible to adjust the mounting position of the peripheral wall while observing the gap between the processed tooth. As a result, it is not possible to optimize the gap between the tooth receiving and treated teeth when the peripheral wall is attached, and there is a drawback that problems such as insufficient treatment or damage to the grain and grain clogging in the gap tend to occur. there were.

An object of the present invention is to eliminate the above-mentioned conventional drawbacks.

[Means for Solving the Problems]

In order to achieve this object, the second product reducing unit according to the present invention constitutes a detachable peripheral wall portion, and a peripheral wall portion body having a tooth receiving member and a position adjustable in the axial direction of the processing rotor. An attachment portion to be attached to the case, means for restricting the position of the peripheral wall portion body at a predetermined position in the axial direction with respect to the attachment portion, and attachment means for detachably attaching the peripheral wall portion body to the attachment portion. It is characterized by being provided.

[Action]

That is, as a mounting form of the peripheral wall portion, a working form in which the mounting portion is first mounted to the processing case and the peripheral wall portion main body is mounted to the mounting portion can be adopted. When mounting the mounting portion to the processing case, the positional relationship of the mounting portion in the axial direction of the mounting portion with respect to the processing rotary body in the processing case can be easily grasped visually, so that an arbitrary shaft can be attached to the processing rotary body. The mounting portion can be mounted on the processing case so as to be located at the core direction position.

On the other hand, in the mounting of the peripheral wall main body to the mounting portion, the axial direction position of the peripheral wall main body with respect to the mounting portion is uniformly determined by the restricting means. Therefore, the mounting portion is adjusted to the axial center position that makes the axial direction position of the tooth receiving portion of the peripheral wall portion main body relative to the processing rotary member appropriate, and the mounting portion is mounted on the processing case. The position of the tooth in the axial direction with respect to the processing rotating body can be optimized.

[Effect of device]

As a result, according to the present invention, it is possible to reliably carry out the intended second object processing while the peripheral wall portion having the tooth receiving member is detachable so that the maintenance and inspection can be advantageously performed.

As shown in FIG. 3, a discharge port (23) is formed in the vertical wall (22) of the second object recovery section (14) at the end of conveyance, and the second screw (14a) is formed from this discharge port (23). A processing case (17) for receiving a second product supplied through the processing case (17) is provided, and the processing rotating body (D) is arranged in the processing case (17). A second vertical feed screw conveyor (20) for returning the second product onto the swing selection device (5) of the selection section (B) is connected via a connecting case (18).

As shown in FIGS. 3 and 4, the processing rotating body (D) projects the end shaft portion of the second screw (14a) into the processing case (17), and then the second screw (14a). The four mounting plates (15) facing the circumferential direction are mounted at 90 ° intervals in the circumferential direction on the terminal shaft portion of the.
A plurality of processing teeth (16) are attached at intervals in the axial direction.

The processing tooth (16) is in the shape of a flat blade, and is used to handle and process the second material sent by the second screw (14a) to form single particles.

In the processing case (17), a peripheral wall portion facing the discharge port (17a) is detachable, and is configured as a lid (24) that opens the cleaning port (21) to the inside of the processing case (17) by detachment. In the lid (24), the treatment tooth (16) is inserted between the treatment teeth (16) in the mounted state, that is, the treatment tooth (16) overlaps with the treatment tooth (16) in the axial direction to treat the treatment tooth (16). The three toothed teeth (24a) are attached to assist the movement.

In the lid (24), as shown by the solid line in FIG. 6, the thickness (L) of the tooth (24a) is small and the gap between the tooth (16) and the treated tooth (16) is large, so that the grain of soybeans or the like is mainly used. The one with a large diameter that is used when expanding, and the thickness (L) of the tooth (24a) that is large as shown by the chain double-dashed line in Fig. 6 and that the gap between the tooth (16) is small. , There are a plurality of types having different thicknesses (L) of the teeth (24a), such as those used for threshing of rice, wheat and the like having a small particle size.

As shown in FIG. 1, the lid (24) is provided with two mounting portions (hereinafter referred to as mounting seats) (24c) for mounting on the processing case (17) and the teeth (24a). It is composed of a lid body (24b).

The mounting seat (24c) has an L-shaped cross-section, and in one piece thereof, a portion of the processing case (17) that faces the cleaning opening (21) in the circumferential direction and is opposed to the cleaning opening (21).
