The utility model provides a swing operation head of articulated flexible axle in area, swing operation head includes the equipment body, the swing arm, and the operation head, transaxle axle bed and flexible axle, wherein the flexible axle passes through the flexible axle mount pad and articulates on the transaxle axle bed. The utility model discloses because the extra resistance that the flexible axle installation angle is invariable and bring when can avoiding the swing arm activity for the swing arm rotates more in a flexible way.

Description

Swing type operation head with hinged flexible shaft

Technical Field

The utility model relates to engineering, the relevant field of gardens and agricultural machine has specifically designed a take oscillating operation head of articulated flexible axle.

Background

In the agricultural field, the demand on the obstacle-avoiding mower is more and more strong mainly in fruit tree planting areas, but when the operation height and angle of the obstacle-avoiding cutter head need to be adjusted independently, only an independent power mode such as a hydraulic motor or a motor can be adopted for the obstacle-avoiding mower, so that the high cost and high selling price are brought, and the further popularization and application of the machine are restricted. However, if the transmission flexible shaft fixedly connected with the two ends is directly adopted, when the obstacle avoidance cutter swings, the obstacle avoidance can generate continuous change of the connection angle of the flexible shaft, so that certain reverse torque is formed inside the flexible shaft, and the flexibility of swinging of the obstacle avoidance cutter is reduced. Whether the problem can be effectively solved or not becomes a decisive factor for determining whether the flexible shaft can be successfully applied to the machines.

Similarly, in the field of tools and machinery for other flexible shaft applications, such solutions are also needed for non-manual operation where the working head swings regularly.

Disclosure of Invention

The utility model provides a swing operation head of articulated flexible axle in area, swing operation head includes the equipment body, the swing arm, the operation head, the axle bed of drive, flexible axle and flexible axle mount pad, and wherein the flexible axle passes through the flexible axle mount pad and articulates on the axle bed of drive. The utility model discloses because the flexible axle installation angle is invariable and the extra resistance that brings when can avoiding the swing arm activity for the swing arm rotates more in a flexible way.

The utility model provides a pair of swing operation head of articulated flexible axle in area, including the equipment body, the swing arm, the operation head, the axle driving seat, flexible axle mount pad and flexible axle. The structure is as follows:

one end of the swinging arm is hinged on the equipment body.

The driving shaft seat is arranged at the other end of the swinging arm, and one end of the driving shaft seat is provided with the operation head.

The flexible shaft is hinged at the other end of the driving shaft seat through a flexible shaft mounting seat.

One end of the flexible shaft is arranged on the flexible shaft mounting seat, and the other end of the flexible shaft is connected to a power source on the equipment body.

Furthermore, the flexible shaft mounting seat is connected with the driving shaft seat in a rotating manner.

Furthermore, the included angle between the input end and the output end of the flexible shaft mounting seat is not equal to 180 degrees.

Furthermore, the flexible shaft mounting base is a gear box, and the interior of the gear box is driven by a pair of bevel gears.

Furthermore, a locking and limiting device is arranged at the joint of the flexible shaft mounting seat and the driving shaft seat in the rotating direction of the flexible shaft connecting seat.

Further, the locking and limiting devices are a push-pull wire rod and a pair of limiting blocks.

Detailed Description

The essential features and advantages of the invention will be further described below with reference to examples, but the invention is not limited to the embodiments listed.

Referring to fig. 1, the oscillating arm 1 is hinged at one end to the apparatus body 2.

The drive shaft seat 3 is arranged at the other end of the swinging arm, and one end of the drive shaft seat is provided with a mowing operation head 4.

One end of the flexible shaft 5 is arranged on the flexible shaft mounting seat 6, and the other end is connected to a power source on the equipment body.

The flexible shaft mounting seat 6 is hinged at the top end of the driving shaft seat 3.

Referring to fig. 1 and 2, a connecting plate 7 connected with a flexible shaft mounting seat 6 is provided with four fixing bolt holes 8, and is fixed on the swing arm 1 through four bolts 9.

Referring to fig. 2, the flexible shaft mounting seat 6 is connected with the connecting plate 7 through 3 bolts 9, and three arc-shaped holes 10 with the aperture slightly larger than the thread specification of the bolts 9 are correspondingly arranged at corresponding positions of the connecting plate 7.

At the corresponding position on the swing arm 1, there are three arc holes 11 whose bore diameter is slightly larger than the external diameter specification of the bolt 9 head.

The flexible shaft mounting seat 6 and the driving shaft seat 3 fixedly mounted by the swing arm 1 form a rotation link with a limited rotation range, the

circular holes

10 and 11 play a role in limiting the rotation in the circumferential direction, and the circular hole 10 plays a role in limiting the play of the flexible shaft mounting seat in the axial direction.

A spline output shaft 12 of the flexible shaft mounting seat 6 is inserted into a spline hole of a transmission shaft 13 of the driving shaft seat 3.

The input end of the flexible shaft mounting seat 6 is the left side, the output end is downward, the included angle between the input end and the output end is less than 180 degrees, and a pair of bevel gears is arranged inside the flexible shaft mounting seat 6 for transmission.

As shown in fig. 3, a limiting auxiliary plate 14 is arranged on the flexible shaft mounting seat 6, and a wire hole 15 and a limiting column 16 are arranged on the limiting auxiliary plate.

A nut 17 is arranged on the connecting plate 7 as a limiting block.

The oscillating arm 1 is provided with a wire holder 18 and a corresponding wire 19 is connected to the wire hole 15.

When the equipment starts and stops, the stay wire 19 pulls the flexible shaft mounting seat 6 to rotate to the position where the limiting column 16 is tightly attached to the side face of the nut 17, so that extra impact caused by reaction rotation due to the fact that the flexible shaft mounting seat 6 which is rotatably linked is not locked in the circumferential direction at the moment is avoided.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
