Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a configuration of a cross flow fan that sends a wind from one side to the other in the radial direction, and more particularly to a configuration of a multi-blade cross flow fan formed of resin used for an exhaust fan of a combine.
[0002]
[Prior art]
A cross flow fan is usually arranged with circular side plates on both sides, a large number of blade-like fins are horizontally mounted on the circumferential portion between the side plates, and a drive shaft is provided at the center portion of the side plate, By rotating the drive shaft, the suction shaft is sucked from one side in the substantially diametrical direction and discharged to the other side in the substantially diametrical direction. This cross-flow fan was mostly made of metal since the rigidity of the fins decreased as the width increased.
[0003]
[Problems to be solved by the invention]
However, since the conventional cross flow fan is made of metal, it is heavy and requires a large torque when the cross flow fan is started. In addition, when this crossflow fan is used as a wind exhaust fan arranged behind the combine sorting device, it is arranged downstream of the power transmission mechanism, such as a swing drive of a red pepper or swing sorting device, a conveyor, etc. Since it is necessary to drive simultaneously with the equipment, the burden on the power transmission mechanism has been increased. Moreover, in order to assemble the said fan, the operation | work which welds a some metal member is required, and it took much time, became a structure with a heavy labor cost, and became a high cost. Therefore, there has been a demand for an exhaust fan having a structure that can be easily assembled by reducing the exhaust fan as much as possible.
[0004]

A left / right swing arm 591 is fitted to the support shaft 590, and a connecting rod 592 protruding sideways is pivotally supported at an end of the left / right swing arm 591. An L-shaped arm 593 is formed at the end of the connecting rod 592 so that the ends of the two arms 593a and 593b are pivotally supported on a pivot shaft 594 and formed L-shaped in rear view. . The arm 593a on one side of the L-shaped arm 593 is pivotally supported by the connecting rod 592, the spring 595 is locked to the end of the other arm 593b, and the end of the spring 595 is engaged with the connecting plate 589. The tension arm 587 is rotated about the drive shaft 136 and is brought into contact with the substantially central portion of the belt 583 by the tension roller 588. Therefore, when the open cover 586 is rotated upward, the left / right swing arm 591 is rotated to the left, the connecting rod 592 is moved to the left, and the L-shaped arm 593 is moved as shown by a two-dot chain line shown in FIG. Rotating to weaken the urging force of the spring 595, eliminating tension on the belt 583 by the tension roller 588, causing the belt 583 around the transmission pulley 582 to idle, and transmitting power to the waste disposal processing device 16. It is configured to cut off.
[0052]
Further, as shown in FIG. 29, the waste disposal device 16 is disposed above the waste cutter chamber 600, and the upper portion of the waste disposal device 16 is covered with an upper cover. An input rod 601 is formed in the upper portion of the waste cutter chamber 600, and a waste guide portion 602 is disposed at the front portion of the feed rod 601. A guide rod 603 of the waste guide portion 602 is provided. The middle part of the waste guide part 602 passes through the upper part of the throwing bar 601 and extends to the rear right side along the waste chain 532 toward the rear right side.
[0053]
As shown in FIG. 30, the evacuation guide portion 602 has a guide bar 603 bent in an L shape, a fitting cylinder 604 that slidably fits the guide bar 603, and a fitting cylinder 604 that stands upright. It is composed of a fixed plate 605, a rotating body 606 that fits under the guide bar 603, and a link arm 607 that rotates the rotating body 606. That is, the fixed plate 605 protrudes rearward in a horizontal state to form a placement portion 608, and the fitting cylinder 604 is placed on the placement portion 608. The fitting cylinder 604 is a cylinder having an axial center in the vertical direction, and a pin 609 is inserted from a side portion of the fitting cylinder 604. One end of the guide rod 603 bent to the L-shaped side is inserted into the fitting tube 604, and a spiral groove 604a is formed on the inserted side. The pin 609 is engaged with the groove 604a, and the lower end of the guide rod 603 protrudes downward from the mounting portion 608 and is fitted to the upper portion of the rotating body formed in a cylindrical shape at the lower end portion. A pin 609 protrudes on the outer peripheral surface of the rotating body 606. On the other hand, a fulcrum shaft 610 protrudes rearward from the side of the fixed plate 605, and one end of the link arm 607 is pivotally supported on the fulcrum shaft 610, and a fastening plate 611 protrudes downward from a middle portion of the link arm 607, A wire 612 and a spring 613 are engaged with the lower end portion of the fastening plate 611. The other end of the spring 613 is engaged with the mounting portion 608 to urge the link arm 607 to rotate upward, and the wire 612 is operated by a lever (not shown) provided in the operating portion to be linked arm. 607 is rotated downward. Further, the other end of the link arm 607 is formed in a rod shape, and a pin 614 protruding from the rotating body 606 is gripped using the rod of the link arm 607.
[0054]
In this way, when discharging the waste into the field without cutting it or binding the waste using a bundling device, the guide rod 603 of the waste guide portion 602 extends along the lower surface of the waste chain 532. It is arranged in a shape. When the wire 612 is pulled by operating the lever, the link arm 607 is rotated downward, the rotating body 606 is moved downward, and at the same time the pin 614 of the link arm 607 is rotated by the length L. Yes. When the rotating body 606 is rotated while being moved downward, the guide rod 603 is also slid downward and the groove 604a is rotated along the pin 609. Therefore, the other end of the guide rod 603 is connected to the exclusion chain 532. The guide bar 603 is stored in the left-right direction while moving downward from the lower surface of the guide. When the guide rod 603 of the evacuation guide portion 602 is accommodated, the slag held by the sewage chain 532 is thrown into the slag cutter chamber 600 along the slag 601 and the slag cutter 17 The excrement is cut using
[0055]
【The invention's effect】
Since it comprised as mentioned above, this invention has the following effects.
Since it was comprised like Claim 1, it will become possible to assemble simply by inserting a fin in a support plate, and welding etc. are unnecessary and manufacturing cost can be reduced.
Since the cross flow fan is formed of synthetic resin, the weight of the fan can be reduced, the driving torque of the fan can be reduced, and the load on the engine and the power transmission mechanism can be reduced. be able to.
