JPH0576232U - General-purpose combine harvester dust removing device - Google Patents

Abstract

(57) [Summary] [Purpose] A general-purpose combine harvester can effectively prevent dust from being generated at the cutting section when the soybeans are harvested from falling on the operator in the driver's seat. [Structure] In a general-purpose combine having a driver's seat B provided behind a cutting unit A including a take-up reel 1, a cutting blade 2, a take-up auger 3 and the like, a rotatably mounted on a platform 4 as described above. A large number of suction holes 5 are formed on the outer peripheral surface of the scraping auger 3, and an axial fan portion 6 is formed inside the scraping auger 3 near one end side thereof so as to be capable of being blown by the rotation of the auger. The side plate 7 of the platform 4 facing one end of the scraping auger 3 has a dust discharge hole 8 formed therein.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a general-purpose combine harvesting-side dust removing device capable of discharging dust generated in a harvesting portion at the time of harvesting soybeans to the lateral side of the harvesting portion.

[0002]

[Prior Art]

 Conventionally, in a general-purpose combine that is configured by equipping the driver's seat behind the reaping section consisting of the scraping reel, cutting blade, scraping auger, etc., when harvesting soybeans, etc. The generation of dust is even more pronounced.

[0003]

[Problems to be solved by the device]

 As a result, dust fell on the driver's seat behind the mowing unit, making it difficult for the operator to drive and having poor hygiene.

[0004]

[Means for Solving the Problems]

 The present invention has been devised so as to solve such a problem and to preferably implement it with a simple structure, and therefore, there are a large number on the outer peripheral surface of the scraping auger rotatably mounted on the platform. And a side plate of the platform facing the one end side of the scraping auger while forming an axial flow fan portion inside the scraping auger near one end side thereof so as to be able to generate air by the rotation of the auger. It is configured with a dust discharge hole.

[0005]

[Action]

 Therefore, as the scraping auger scrapes the soybeans harvested by the cutting blade while scraping with the scraping reel, the internal axial fan unit also rotates and wakes up. The dust generated from the mowing unit can be sucked through the suction hole, and can be discharged as it is from one end of the scraping auger through the dust discharging hole to one side of the mowing unit that is away from the operator.

[0006]

【Example】

 FIG. 2 shows a side view of the front part of the general-purpose combine, and a threshing section C equipped with a cylinder 10 and the like and a grain tank 11 are mounted above both crawlers 9, and in front of the threshing section C, The cutting chamber A, which has a feeder chamber D that can be moved up and down by a hydraulic cylinder 13 and has a feeder 12 installed therein, is connected to the front of the feeder chamber D. The scraping auger 3 having the fingers 14, 14 having a finger 15 that can freely move in and out at the center side is rotatably laid horizontally, and the upper side of the cutting blade 2 provided in front of the platform 4 on the front side. A rotating take-up reel 1 is installed on the control column 17, and a steering column 17 is provided before and after the step 16 installed on the lateral side of the feeder chamber D behind the lateral side of the mowing section A. And deploy driver's seat B Similarly constituting conventional type structure Te.

A large number of suction holes 5 capable of absorbing dust are formed on the outer peripheral surface of the entire sweeping auger 3, and one end side of the sweeping auger 3 which is a side away from the driver's seat B is opened or is attached to an end surface. An opening is formed, and an axial flow fan portion 6 capable of being blown by the rotation of the auger is formed inside the scraping auger 3 near one end side. It consists of four extending blades 6a. The tip of each blade 6a is fixed to the inner surface of the scraping auger 3 and the rotary shaft 18 is fitted to the boss 6b. The side plate 7 of the platform 4 facing the one end side which is the side is formed with a plurality of dust discharge holes 8.

Therefore, at the time of harvesting operation, the axial fan unit 6 rotates together with the rotation of the scraping auger 3 that scrapes the soybeans cut by the cutting blade 2 while scraping the scraping reel 1. Due to the wind, the dust generated from the cutting section A is sucked through the many suction holes 5 on the peripheral surface of the auger, and then, as it is, from the one end side end of the scraping auger 3 The dust can be discharged to one side of the mowing section A away from the operator in the driver's seat B through the dust discharging hole 8 as indicated by an arrow in 3.

[0009]

[Effect of the device]

 Thus, according to the present invention, the internal axial fan unit 6 is rotated together with the rotation of the scraping auger 3 for scraping the soybeans harvested by the cutting blade 2 while scraping by the scraping reel 1 to generate air. As a result, the dust generated by the mowing section A is sucked in through the suction hole 5 on the auger peripheral surface by the wind, and the dust is discharged from the end of the scraping auger 3 through the dust discharge hole 8 to the operator. The dust can be discharged to one side of the reaping section A, which is farther away, and the operator in the driver's seat B can operate comfortably without being troubled by dust as in the conventional case. It has a feature that it can be installed in 3 and have a compact structure, and can be suitably implemented.
