Abstract

(57) [Abstract] [Purpose] The present invention facilitates the taking of grain culms sent from the reaping section into the handling chamber, and improves the efficiency of threshing work. [Structure] The starting end portion of a cylindrical handling cylinder 2 which is mounted on the handling chamber 1
It is formed in a cone shape whose diameter gradually decreases toward its starting end, and the outer peripheral rotation locus of the handling teeth 21 provided on the outer circumference of the handling cylinder is formed on the peripheral surface of the cone-shaped portion 2a at the starting end of the handling cylinder. It is characterized in that a screw auger 20 having substantially the same outer peripheral rotation locus is provided.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a normal combine threshing device.

[0002]

[Prior art]

 Conventionally, in this type of ordinary combine harvester, at least the starting end side is formed into a cone shape (conical shape), and the handling cylinder provided with a screw auger on the cone-shaped peripheral surface is axially arranged. There is known an axial flow type threshing device in which is housed in the handling chamber so that it is in the front-back direction.

The screw auger at the starting end of the handling cylinder has a configuration in which this rotation diameter is parallel to the peripheral surface of the cone, that is, the rotation locus of the outer peripheral edge on the starting end side of the auger is at the starting end of the handling cylinder. It was generally configured in the same shape as the cone shape.

[0004]

[Problems to be solved by the device]

 As a result, the harvest of grain culms sent from the reaping section into the handling room was poor, leading to a reduction in threshing productivity. The present invention is intended to solve such a problem, and the following technical measures have been taken to achieve this object.

[0005]

[Means for Solving the Problems]

 That is, according to the technical means of the present invention, the starting end portion of the cylindrical handling cylinder 2 which is axially mounted in the handling chamber 1 is formed into a cone shape in which the diameter is gradually reduced toward the starting end, and the handling cylinder is also provided. A screw auger 20 having an outer peripheral rotation track substantially the same as the outer peripheral rotation track of the handle teeth 21 provided on the outer periphery of the handle cylinder is provided on the peripheral surface of the cone-shaped portion 2a at the starting end. Is a feature.

[0006]

Therefore, according to the present invention, since the screw auger at the starting end of the handling cylinder has a larger rotational diameter of protrusion from the conical peripheral surface at the starting end of the handling cylinder, The grain culms sent into the handling room can be quickly and reliably taken in, improving the threshing treatment performance and improving the work efficiency.

【Example】

 a is a machine of the threshing part A, 1 is a handling room that is configured and provided in the machine a, 2 is a handling body that is internally erected in the handling room 1 with its axial direction in the front-back direction, 12 Is a grain culm receiving opening provided in the lower part on the front end side of the threshing unit A so that the whole culm culms harvested by the reaping unit and sent from the reaping unit side can be received in the handling chamber.

The threshing section A is used as a thresher type so as to be assembled into a thresher type combine and a self-shedding type combine by changing the form of the cutting section to be combined with each other. Therefore, the handling room 1 provided on the upper half side of the body a of the handling room 1 has a horizontal shape on the upper side of the front end side thereof and on the outer side side of the handling room 1. A grain culm supply port for supplying the tip side of the grain culm holding the stocker side to the built-in feeder 3 is provided, and in the upper part of the rear end side of the handling chamber 1, the front side is provided. A threshing opening 11 is provided for discharging the threshed grain culms, which have been supplied to the handling chamber 1 by the feed chain 3 and have been subjected to the threshing action by the handling barrel 2, by the feed chain 3. There is.

The handling barrel 2 is laterally suspended in the handling chamber 1 with its axial direction along the front-back direction of the machine body a, and has a cone-shaped portion 2a formed on the front end side which is the front end side thereof. The peripheral surface is equipped with a screw auger 20 wound in a double-threaded manner, from the rear end of the cone-shaped portion 2a to the end portion of the handling room 1 facing the outlet 11. Handle teeth 21 are provided on the circumferential surface of the body main body 2b formed in a cylindrical shape so as to be continuous in diameter.

Further, the screw auger 20 has a cone-shaped portion 2 a closer to the starting end side so as to have an outer peripheral rotation locus which is substantially the same as an outer peripheral rotation locus of the handling teeth 21 provided at least on the outer circumference of the handling cylinder 2. The rotation diameter of the protrusion from the peripheral surface is large. The grain culm receiving opening 12 has a left and right opening width d within the left and right width D of the handling room 1 as shown in FIG. It is arranged so as to be located across both sides, and is installed at the lower part on the front end side of the handling room 1.

In the figure, W is a step, the starting end of the feeder chain 3, 13 is a feeder, 13 a is a feeder house, 14 is a net for the handling room, 15 is a dust outlet, and 40 is A rocking shaft for operating a rocking / sorting shelf provided in the wind-selecting section 4 below the handling room 1, 41 for operating the Kara-mino for feeding the screening air to the air-selecting section 4, and 42 for the No. 1 screw shaft. , 43 are No. 2 screw shafts, and 44 is a dust outlet of the wind selecting unit 4.

The lateral width of the feeder house 13a is narrower than the left and right width D of the handling room 1, and the feeder 13 has a rotation locus on the side facing the handling room 1 It is provided so as to intervene closer to the inside of the handling room than the front side plate 45.
