Abstract

(57) [Summary] [Purpose] It is possible to smoothly introduce grain culms into the grain handling room without retaining them at the grain culm inlet of the handling room. [Structure] A handling cylinder 3 having screw teeth on its outer periphery is provided in a handling chamber 4 rotatably around a longitudinal axis P and a handling chamber 4 is provided.
A grain stalk scraping member 9 made of an elastic material is attached to the outer peripheral surface of the front part of the handling barrel 3 which faces the grain stalk introduction port 8.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an all-cullet-type combine harvester in which a handling cylinder having screw teeth on its outer periphery is provided in a handling chamber so as to be rotatable around a longitudinal axis.

[0002]

[Prior Art]

 Conventionally, this type of all culm input type combine harvester has been introduced so that the grain culm introduced from the grain culm introduction port of the handling room can be treated while being transferred backward by the screw teeth provided in the handling barrel. Was scraped into the handling room with a scraping member consisting of a rigid member connected to the screw teeth.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional structure, the amount of protrusion of the outer edge of the scraping member from the handling cylinder is limited so that the scraping member does not collide with the ceiling wall of the handling chamber, etc. A large gap was created between the grain culm introduction port and the outer edge of the scraping member, and the grain culm was likely to stay in this gap.

The present invention has been made in view of the above-mentioned circumstances, and is an all-cullet throwing type converter capable of smoothly introducing grain culms into the handling chamber without retaining the grain culms at the grain culm introduction port of the handling room. The purpose is to provide the inn.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the all culm throw-in type combine according to the present invention is provided with a handling cylinder provided with screw teeth on the outer circumference in the handling chamber so as to be rotatable around the longitudinal axis, and at the same time, to introduce grain culms in the handling chamber. It is characterized in that a grain culm scraping member made of an elastic material is attached to the outer peripheral surface of the front part of the handling cylinder facing the mouth. The actions and effects of this characteristic configuration are as follows.

[0006]

[Action]

 That is, since the grain-scraping member is made of an elastic material, even if the grain-scraping member is provided with an outer edge having a large outer diameter such that it collides with the ceiling wall of the handling room, etc. Since the damage to the culm scraping member, the ceiling wall of the handling room, and the like is suppressed, it is possible to configure a grain culm scraping member having a shape that does not allow a large gap in the grain culm introduction port of the handling room.

[0007]

[Effect of the device]

 Therefore, the grain culm scraping member configured in a shape that does not allow a large gap in the grain culm introduction port of the handling room immediately introduces the grain culm transferred to the grain culm introduction port of the handling room into the handling chamber and the grain. It has become possible to solve the problem that the culm stays in the grain culm inlet of the handling room.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a threshing device A of an all culm-type combine harvester comprising a threshing unit 1 and a sorting unit 2. In the threshing unit 1, a handling cylinder 3 that rotates around a front-rear direction axis P is mounted over the front and rear of a handling chamber 4, and a receiving net 5 is arranged below the handling barrel 3 and the handling barrel 3 is provided. A screw-shaped screw tooth 6 is provided on the outer periphery of the grain so that the grain culms to be threshed introduced into the handling chamber 4 are transferred to the rear side in a state where the threshing operation is given.

The grain stalks mowed by the pre-crop treatment section provided in the front part of the combine of the fuselage are transported rearward by the transport belt 7 and fed to the grain stalk introduction port 8 below the front part of the handling chamber 4. As shown in FIGS. 1 and 2, on the outer peripheral surface of the front portion of the handling barrel 3 facing the grain culm introduction port 8, as shown in FIGS. 1 and 2, a plate-shaped grain culm scraping member 9 made of an elastic material of rubber or synthetic resin. Are attached in a protruding state. As shown in FIG. 1, the outer periphery of the grain culm scraping member 9 is formed so as to extend to the vicinity of the bottom surface of the grain culm inlet 8 and is also scraped. In order to give a rearward transfer force to the grain culm, the grain culm is attached to the outer peripheral surface of the front part of the handling barrel 3 in an inclined posture in a state of drawing a spiral.

With the above configuration, since there is almost no gap between the outer edge of the grain culm scraping member 9 ... And the bottom part of the grain culm inlet 8, the grain culm transferred to the grain culm inlet 8 Will not be retained and will be scraped into the handling chamber 4 by the grain culm scraping member 9. Further, even if the grain-scraping member 9 ... Collides with the wall near the handling cylinder 3 such as the ceiling wall portion of the case 4a of the handling chamber 4, the grain-scraping member 9 Since the grain-scraping member 9 is bent by the elasticity of the ..., it is possible to avoid damaging the ceiling wall portion of the case 4a.

It should be noted that reference numerals are added to the claims of the utility model for convenience of comparison with the drawings, but the invention is not limited to the configurations of the accompanying drawings by the entry.
