Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a shelling device, and more specifically, it opens and closes a handle case on the upper side on which a handle barrel is rotatably mounted on a lower fixed case. The present invention relates to a structure for attaching and detaching a straw cutting blade in a shelling device which is supported freely.

[Conventional technology]

Conventionally, as a shelling device configured as described above,
There is one shown in 59-150232 publication, and in this conventional example, a blade holder and a straw cutting blade are provided for a fixed case on the lower side, and in a portion located above the blade holder. A lid that can be opened and closed is provided.

[Problems to be solved by the device]

Here, considering the force acting due to the rotation of the handling cylinder during the shelling work, the handling cylinder rotates at high speed during the shelling work, and for example, when a large amount of straw is generated in the handling chamber, A strong shear force is generated when the straw is cut between the handle tooth of the body and the straw cutting edge, and when this shear force is generated, the distance between the handle cylinder and the straw cutting edge is increased. A strong force acts in the direction of the attempt. Therefore, as in the conventional example, a straw cutting blade is provided on the fixed case side,
In the case where the handling cylinder is erected on the fixed case so as to be swingable, the handling case is fixed with a strong force every time the straw is cut between the handling tooth of the handling barrel and the straw cutting blade. As a result of the force acting to open the handle case against,
Not only is a strong force intermittently applied between the fixed case and the handle case to easily generate vibration, but also a strong force is applied to the support shaft that supports the handle case in a swingable manner with respect to the fixed case. Since it acts, the strength of this support shaft is required to be increased.

Further, since the straw cutting blade needs to be replaced at an appropriate time, a shelling device that enables the replacement of the straw cutting blade without any trouble is also desired.

The object of the present invention is to make the handle case openable and closable so that vibration is unlikely to occur during work, and the strength of the support shaft that opens and closes the handle case does not need to be increased so much and the straw cutting blade is used. The reason is to reasonably construct a shelling device that can be easily replaced.

[Means for Solving the Problems]

A feature of the present invention is that the upper side of the handling case, which is rotatably mounted on the handling case, is pivoted around the axis of the lower fixed case in a posture parallel to the axis of rotation of the handling case. A support blade is provided on the side of the handle case that has a large number of straw cutting blades, and a space for attaching and detaching the straw cutting blades is formed above the support blade stand. The lid body for opening and closing is supported at the upper surface position of the shelling device, one end of which is swingably supported around the axis parallel to the axis on the side of the fixed case and the other end is closed. It is provided so as to be brought into contact with the upper surface of the handling case, and its operation and effect are as follows.

[Action]

According to the above feature, at the time of work, a large amount of straw is generated inside the handling chamber, and the force resulting from the strong shearing force between the handling tooth of the handling cylinder and the straw cutting blade is generated by the straw cutting blade and the handling cylinder. Even if it acts in the direction of separating the handle barrel, the straw cutting blade is provided on the handle case side together with the handle cylinder, so this force does not act on the side that opens the handle case unlike the conventional example. In addition, the force resulting from the shearing force does not have to act on the support shaft that swingably supports the handling case. Further, since the blade cutting edge of the handle case located above the fixed case is equipped with straw cutting blades, even when the straw cutting blade is replaced by opening the lid on the top surface of the device, it can reach deep positions. Work can be done through the space for attaching and detaching the straw cutting blade without inserting a tool, and the opening / closing axis of this lid is set in parallel with the opening / closing axis of the handle case. Since the one end is brought into contact with the upper surface of the handling case in a closed posture, the gap between the fixed case and the handling case can be closed with the lid at the same time, regardless of whether the handling case is configured to be openable and closable. At the time of the opening operation of the handling case, the lid is naturally opened with the end portion of the lid abutting the handling case without special manipulation of the lid.

[Effect of device]

Therefore, in the case where the handle case is configured to be openable and closable, vibration is unlikely to occur during work, and the strength of the support shaft that opens and closes the handle case does not need to be increased so much and the lid can be used reasonably. Thus, a shelling device that can easily replace the straw cutting edge was constructed.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 4, a handling cylinder (2) that gives a handling action to the shells conveyed by the feed chain (1) is arranged inside the handling room (A), and the lower side of the handling room (A) is located. An oscillating sorting mechanism (4) for arranging an arcuate receiving net (3) along the circumferential direction of the handling cylinder (2) and sorting the processed material from the handling chamber (A) by its oscillating motion, Karato (5) that sends the sorting wind, the first screw (6) that collects the shell grains from the swing sorting mechanism (4), and the second screw (7 that collects the second product from the swing sorting mechanism (4). ), A thrower returning mechanism (8) for sending the second object from the second screw (7) to the handling chamber (A), and a dust-exhausting fan (9) for sucking and discharging the dust inside the apparatus to configure a shelling device. To do.

As shown in FIG. 1 and FIG. 2, this shelling device comprises a lower fixed case (1
