摘要： PROBLEM TO BE SOLVED: To provide a thresher having a swing separator designed to be separable into a separatory section and a swinging actuation section so as to leave the swinging actuation section in the machine body and enable only the separatory section to be taken out of the machine body, thus reducing the weight of the element and facilitating taking out the element out of the machine body, in view of the fact that, conventionally, such a swing separator located under a threshing cylinder chamber and been designed to be taken out of the machine body nearly as a whole thereof, that is, a great portion of the swinging actuation section has been necessitated to be taken out together with the separatory section, therefore the element to be taken out has become heavy as a whole and has been difficult to be detached. SOLUTION: This thresher is such that a swing separator as a component thereof is made up of a separatory section functioning to receive a threshed matter from a threshing cylinder chamber and sieve and separate the threshed matter under swinging transfer and a swinging actuation section functioning to subject the separatory section to swinging actuation back and forth, and is designed to be separable into the separatory section and the swinging actuation section so as to leave the swinging actuation section in the machine body and enable only the separatory section to be taken out of the machine body.

摘要： PROBLEM TO BE SOLVED: To solve the problem that, in the conventional threshing machine, the cereal grains separated from dust waist in the latter half of an exhaust dust treating chamber are exhausted from an exhaustion opening onto a shaking separation sieve, and these grains tend to be directly sucked into an immediately following sucking type dust exhaustion machine and resultantly the grains are lost outside the machine. SOLUTION: A second exhaust dust treating chamber 5 separated with a leaking material 4 is provided on the lower side of a first exhaust dust treating chamber 3 that exhaustion-treats the dust waste relayed from a threshing chamber 1. The second exhaust dust-treating chamber 5 conveys the dust waste leaking down from the first exhaust dust-treating chamber 3 in the opposite direction to the conveying direction of the shaking separation sieve 2 and is exhausted on the upper side above the shaking separation sieve 2.

摘要： PROBLEM TO BE SOLVED: To solve such a problem in which radial load acts when stretchably moving force is transmitted in a conventional carrying spiral and the sliding lacks smoothness, and further, the production cost is up. SOLUTION: This invention has a constitution capable of stretchably moving a movable carrying cylinder 4 having opened grain discharge port 3 at the top to a fixed carrying cylinder 6 by a stretchable driving device 5. Plural divided spirals of a stretchable carrying spiral 8 of the above movable carrying cylinder 4 are slidably fitted into a transmission shaft 9 only in the axial direction and springs are put among these divided spirals to stretchably constitute the cylinder 4. The springs having stronger stretching pressure are used on the higher part side in carrying direction of the movable carrying cylinder 4 and the springs having weaker stretching pressure are used on the lower part side thereof.

摘要： PROBLEM TO BE SOLVED: To solve the problem of the increased discharge of disposed chaff caused by the screening defect at the chaff discharging side even by setting the grain screening side to the best condition in a conventional chaff sieve controlling the screening space by adjusting the angles of all screening plates based on the detection information of a grain sensor. SOLUTION: The thresher 6 is provided with a threshing chamber 1, a disposed chaff treating chamber 2 to treat the chaff discharged from the threshing chamber, an unhulled rice grain sensor 4 and a disposed chaff sensor 5. The shaking screening racks 8 are provided with chaff sieves 9 positioned at a grain size selection zone A containing a large amount of flowing grains and a disposed chaff selection zone B containing a large amount of flowing straw dust. The chaff sieve 9 is constructed in a manner to enable the independent control of the screening gaps of the selection plates 10a, 10b of the grain size selection zone A and the disposed chaff selection zone B. The selection gap of the selection plate 10b is controlled based on the detection information of the disposed chaff sensor 5 and that of the other plate 10a is controlled by the information transmitted from the unhulled rice grain sensor 4.

摘要： PROBLEM TO BE SOLVED: To reduce the third chaff sieve loss more than the conventional by solving the problem that the conventional grading controller narrows the selection intervals of the chaff sieve, when the amount of grain flow detected by the grain sensor is less than the standard value, but the adjustment cannot be related to the amount of the sucked air of the suck-dusting air whereby there happens no change in the dusting air outward. SOLUTION: In order to solve the problem, the selection intervals of the chaff sieve 1 and the air-sucking area of the suck-dusting machine 2 are interrelated and automatically controlled on the basis of the exhaust amount of the waste straw, in addition, when the selection interval is controlled on the narrow side, the air-sucking area also synchronously is controlled to the narrow side.

摘要： PROBLEM TO BE SOLVED: To eliminate problems such as difficulty and low efficiency in the removal of rachis-branches due to the absence of the mutual jostles of unhulled rice grains and the deterioration in the grading performance due to the presence of unhulled rice grains having rachis-branches in a large amount under conventional technology in which the rice grains having the branches are jumped up, thrown and carried around the inner wall of a treating chamber and simultaneously threshed between the treating teeth of a rotated treating cylinder and a treating net. SOLUTION: A second treating chamber 11 which receives and retreats the second grade grains from a threshing chamber and in which a second treating cylinder 11 is pivotally spun is disposed on one side of the threshing chamber 9 in which a threshing cylinder 8 is pivotally spun or at a proper rear position. A discharging port 15 is opened and disposed on the final carrying end side of the second treating chamber. An openable or closable resistance plate 16 which is always energized in the closing direction so as to impart a proper resistance to the discharging port in the counter-carrying direction is disposed in the discharging port 15.

摘要： PROBLEM TO BE SOLVED: To protect an operator from the heat or the cold by means of blowing an air-conditioning airflow of a cooler or a heater against the operator by providing an operator's seat on a travelling car body, where a blow off port of an airflow is sent from an air conditioner at an adjacent position and a blow off direction of the air current is optionally controlled. SOLUTION: An operator's seat 2 is arranged on the front part right side toward the forwarding direction of a travelling car body 1, and an operator can be seated and drive. Additionally, an air conditioner 3 is set with an accessory apparatus at a back position of the operator's seat 2 and sends a controlled airflow to air ducts 9, 9'. These air ducts 9, 9' are formed in a T shape and are constituted to blow air by separating it to both left and right sides. Furthermore, the air conditioner 3 starts air conditioning work by a heater and a cooler by properly using fleon gas and hot water circulated by a gas pipe 10 and a hot water pipe 11. Consequently, the operator is protected from the heat as a conditioned air current is sent by the simple air conditioner 3 even in the hot season of summer.
