Abstract

(57) [Summary] [Purpose] The spiral rotor can be effectively attached to the rotary working machine with the pawl shaft attached. A rotary working machine constructed by mounting both flanges 3a, 3b on both ends of a claw shaft 2 having a large number of tillage claws 1 on both sides of a transmission case 4 and a bearing stay 5 side, respectively. The spiral rotor A formed into a large diameter so as to approach the outer circumference of the group is divided into a plurality of parts, and both ends of each divided spiral rotor a are attached to and detached from both flanges 3a and 3b of both ends of the pawl shaft 2, respectively. It is configured by providing both arc-shaped flanges 6a and 6b that can be freely fixed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a spiral rotor mounting structure for a rotary working machine capable of mounting a spiral rotor on a portion where a pawl shaft is mounted.

[0002]

[Prior art]

 Conventionally, in a rotary working machine in which both flanges at both ends of a claw shaft having a large number of tillage claws are mounted on both sides of a transmission case and a bearing stay side, when the spiral rotor is mounted, the claw shaft is After removal, both ends of the spiral rotor are attached to the transmission case and bearing stay side, respectively.

[0003]

[Problems to be solved by the device]

 However, the work of mounting the spiral rotor after removing the pawl shaft in this way is difficult and difficult, and in particular, the work of attaching and detaching the pawl shaft having the tillage claw group is very difficult and time-consuming. Was there.

[0004]

[Means for Solving the Problems]

 The present invention solves such a problem and devises so that the spiral rotor can be effectively attached.Therefore, the spiral rotor formed with a large diameter so as to approach the outer circumference of the tillage claw group is divided into a plurality of parts. Both ends of each of the split spiral rotors are provided with arc-shaped flanges that can be detachably fixed to the flanges on both ends of the claw shaft.

[0005]

[Action]

 Therefore, when installing a spiral rotor between the transmission case of the rotary working machine and the bearing stay, leave the pawl shaft attached and attach both flanges on both ends of each divided spiral rotor to the pawl shaft. It can be easily attached by fixing it to both flanges on both ends with, for example, bolts and nuts.

[0006]

【Example】

 FIG. 1 is a rear view schematically showing a part of the rotary working machine. The lower part of each side of the rotary working machine, which is connected to the rear of the agricultural tractor so as to be movable up and down, has a transmission for transmitting to a central input gear case 7. A case 4 and a bearing stay 5 are hung vertically, and both flanges 3a and 3b are fixed to both ends of a long pawl shaft 2 having a large number of tillage pawls 1. One flange 3a is the transmission case. 4 is connected to a mounting flange 9a fixed to the tip of the drive shaft 8 protruding from the lower part of the bearing 4 through a plurality of bolts and nuts 10, while the other flange 3b is mounted on the lower part of the bearing stay 5 by a mounting flange. The structure is similar to that of the conventional structure in which the rotary cover 11 is attached to the upper portion of the pawl shaft 2 by connecting it to the lunge 9b via a bolt nut, but a plurality of mounting holes 12 into which the bolt nut 10 is inserted are formed. It said respectively have flanges 3a, 3b is as well as the diameter of the disc, the flanges 3a, the outer peripheral portion of the 3b constructed by forming the mounting hole 14 of the multiple capable inserting the bolts and nuts 13, respectively.

As shown in FIG. 5 and FIG. 6, the spiral rotor A formed with a large diameter so as to approach the outer circumference of the group of tillage claws is divided into two spiral rotors a and a having the same shape, At both ends of each spiral rotor a, semi-arcuate flanges 6a and 6b that can be joined to the inside of the flanges 3a and 3b are fixed respectively, and mounting holes 15 that can match the mounting holes 14 are provided. The spiral rotor A may be formed by dividing the spiral rotor A into three parts, although they are formed on the inner peripheral sides of 6a and 6b.

Therefore, when the spiral rotor A is mounted between the transmission case 4 and the bearing stay 5 of the rotary working machine, as shown in FIG. When both end flanges 6a, 6b of a, a are joined to the sides of the flanges 3a, 3b at both ends of the claw shaft 2, respectively, and the bolt nuts 13 are respectively fitted and tightened in the corresponding mounting holes 14, 15, respectively. As shown in FIG. 1, since the spiral rotor A can be easily attached to the outer circumference of the group of tillage claws 1, the spiral rotor A can be used for rotary work.

[0009]

[Effect of device]

 As described above, according to the present invention, when the spiral rotor A is mounted between the transmission case 4 and the bearing stay 5 of the rotary working machine, the pawl shaft 2 is left attached and both ends of each of the divided spiral rotors a are attached. By joining both flanges 6a, 6b to both flanges 3a, 3b on both end sides of the claw shaft 2 and fixing them with, for example, bolts and nuts, the spiral rotor A can be attached, which is troublesome as in the conventional case. The spiral rotor A can be quickly and easily attached and detached without any difficulty, and has a characteristic that it can be suitably implemented with a simple structure.
