Abstract

PURPOSE:To prevent the random splashing of discharged straws and diffuse and release the straws in the rear direction by constituting a combine so as to blow out a grading wind from a winnower toward a discharging straw- releasing and dropping passageway corresponding to a straw-discharging opening. CONSTITUTION:When all amount of reaped grain straws carried from a reaping pre-treating section are fed into a threshing chamber 13, the grain straws are transferred from the side of a feeding opening 16 toward the side of a discharging opening 17 in the threshing chamber 13 with a threshing cylinder 3 and simultaneously threshed between the threshing cylinder 3 and a receiving net 14. The threshed grain straws, etc., are dropped from the receiving net 14 on a lower shaking grading device 21 and the threshed straw residues such as straw dusts are rapidly released and dropped from a discharging opening 19 on the end side of the threshing chamber 13 in the rear direction from the end of the shaking grading device 21. A grading wind from a winnower 19 is blown out from the end of the shaking grading device 21 toward the discharged straws released and dropped from the discharging opening 17.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention supplies the entire amount of reaped husks into a handling chamber equipped with a handling barrel that rotates around the longitudinal axis of the machine body, and This relates to a combine harvester that feeds the entire amount of harvested stalks and culms that are threshed while being transported to the rear.

[Prior art and problems to be solved by the invention] Generally,
In this type of combine harvester, the entire amount of husks supplied into the handling chamber is transferred from the supply port side to the discharge port side of the handling chamber by the handling drum, and then threshed between it and the receiving net. The threshed grains, etc. are leaked from the receiving net to the swinging sorting device below, but the threshed culms, such as culm waste, are discharged from the outlet at the rear end of the handling room (end side of the handling room). I try to release it to the outside.

However, in the past, the discharge port of the handling chamber was located below the terminal end of the oscillating sorting device, which caused the culms to fall onto the oscillating sorting device. was stagnant, leading to deterioration of 1st selection zi1 performance.

Therefore, in order to solve this problem, a sloped guide plate that slopes backward and downward is provided in the part corresponding to the discharge rod side of the handling room to cover the lower part of the terminal side of the a dil+ sorting neck, and to move the culm backward. There is a technology that allows the guide to fall.

(Refer to U.S. Pat. No. 4,266,5130 specification 1)) According to such a configuration, 1111: not only the discharging action of the culm is inhibited, but also stagnation occurs on the inclined guide plate, causing clogging in the discharge section 11. Excessive threshing (:!I' f!
: There was a problem that lowered threshing performance and efficiency.

This problem could be solved by opening the discharge culm at the end of the handling chamber [-1] at a position rearward from the end of the sorting device. may be scattered by the shadow 1'1 of the outside wind, etc., and the 4! A new problem has arisen in which the particles inadvertently enter the I+ sorting device I. and interfere with sorting.

The present invention aims to solve such problems and has the following technical means.

[Means for Solving the Problems] In other words, one technical means according to the present invention is to supply the handling cylinder 3 to the handle 1.1 side of the handling chamber 13 in which the internal shaft is mounted [:l 113
The whole animal to be threshed supplied by the threshing machine is threshed by rotating the handling cylinder 3 while moving the grain toward the rear in the axial direction of the handling cylinder, and the threshed grain is leaked downward from the receiving net 14, and the grain is threshed. ,
The threshing culm is configured to be discharged from a discharge port 17 provided at the rear end of the handling chamber, and below the handling chamber 1 there is a sorting air passage 20 through which sorting air is passed by a pressurized winch 19. A shaker 1 sorting device 21 is provided which sieves the leakage 1~grain from the receiving net 14 while shaking and transporting it rearward.

The threshed grains, etc. are shaken by the receiving net 14 or 61Z! I! The threshed culms leaked onto the Ij sorting device 21 and the threshed culms such as culm waste are discharged from the terminal end side discharge 1] 17 of the handling chamber 13 to the shaker A.
6+ Sorting device 2 It is immediately discharged and dropped backward from the end of the unit.

The sorting air produced by the air pressure winch 19 is blown out from the end of the swinging sorting device 21 and toward the culm from which it is discharged from the discharge culm 17.

〔Effect of the invention〕

According to the present invention, as described below, ! of the handling room! The culms released from Il'71 1 are shaken+lr:)+Sorting device-1-
Although it is possible to improve the sorting performance by preventing the culm from falling into the ground, there is no obstacle such as an inclined guide plate below the discharge point, which prevents culm stagnation, There are almost no problems such as clogging near the discharge part 11, and you can expect a quick and smooth discharge action.

Moreover, even if the culm is affected by the outside wind during discharge and falling, the culm will not be blown away accidentally and will be directed backwards because of the sorting wind created by the pressurized winnowing machine. As a result, it is possible to eliminate the interstitial spots that were diffused and released and entered the oscillating sorting device-1 and hindered sorting. 1) 6 [Example] The following is an implementation of the present invention. An example will be explained based on the drawings. A threshing device 4 is installed on the fuselage 2 equipped with a crawler-type traveling gear 1, and is equipped with a sword-3 that rotates 101 times around the longitudinal axis of the fuselage.
It is equipped with a divider in front of it that separates the erect culms in the field - 50 minutes! A reel 6 that scrapes the culm backwards, a reaping device 7 that reaps the culm that has been raked,
The pre-harvesting device is equipped with an auger 8 that collects the harvested shell culm toward the center and sends it out rearward, and a conveying device 9 that takes over the shell culm sent out to the rear and conveys it to the threshing device 4 by scraping and whiskers. A processing section is installed.

The conveying device 9 has a w411 at the bottom between which the auger 8 and the beater 10 allow grains to leak, and a rotor 12 with a plurality of protrusions 12a that rotates around the horizontal axis is attached to the bottom of the w411. They are arranged in such a way that grain culms can be scraped and conveyed between them and the leakage net 11.

The threshing device I'24 mainly consists of the handling drum 3 and a handling chamber 13 in which it is mounted on an internal shaft, and the handling chamber 13 is constituted by a lower receiving net 14 and an upper cover 15. The harvested husk culm, which is completely thrown into this handling chamber, is transferred in the axial direction of the handling cylinder from the supply port 16 side opened on the front side to the discharge port 17 side opened on the rear side, and then transferred to the receiving net 14. 1 leg between
It is designed to be general.

The sorting device 18 is provided with a swinging sorting device 21 in the sorting air passage 20 through which the sorting air from the pressurized winnower 19 passes, and receives grains leaking from the receiving net 14 of the handling room 13 as L and rearwards. The structure is such that the material is sieved and sorted while being oscillated and transferred.

The discharge port 17 of the handling chamber is configured to open at a position rearward from the terminal end of the swinging sorting device 21, and the sorting air from the pressure winch 19 is directed from the terminal end of the swinging sorting device 21. It is configured to be blown out and blown out from the discharge port 17 toward the culm discharge fall path.

Reference numeral 22 denotes a grain frying belt, which is configured to transport grains leaked from the leakage net 11 to the sorting device 11 for frying.
