Description

Combine knife section

Technical Field

The utility model belongs to the technical field of the harvesting machine technique and specifically relates to a combine cutter moves blade.

Background

At present, a movable blade of a combine harvester is generally fixedly arranged on a blade bar through a rivet, when the blade is worn or damaged and needs to be replaced, the blade needs to be dismounted after the rivet is damaged by using a grinding tool, and the dismounting and mounting operation of the blade is complex, time-consuming and labor-consuming.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects in the prior art, the utility model provides a combine harvester moving blade.

The utility model provides a technical scheme that its technical problem adopted is: the movable blade of the combine harvester comprises a blade, wherein a fixed column is fixedly mounted on the blade, the fixed column is movably mounted on a telescopic column, the fixed column and the telescopic column are connected through an elastic component, a clamping groove is further formed in the blade, and threads are arranged at the end part of the telescopic column.

Further, the telescopic column is installed in a screw hole formed in the cutter bar through threads.

Further, a limiting plate is fixedly mounted on the cutter bar, a limiting column is fixedly mounted on the limiting plate, and the blade is limited under the mounting condition.

Further, the clamping groove is coupled with the limiting column under the installation working condition.

Further, the fixed column and the telescopic column are coaxially mounted with the blade.

The beneficial effects of the utility model are that, the utility model relates to a scheme is through setting up limiting plate and installation screw on the sword strip and set up the installation labour saving and time saving that flexible post and draw-in groove made the blade on the blade, and the dismouting of being convenient for has improved the dismouting convenience of moving the blade effectively.

In the figure, 1, a blade, 2, a clamping groove, 3, a fixing column, 4, a spring, 5, a telescopic column, 6, a thread, 7, a sliding chute, 8, a sliding block, 9, a cutter bar, 10, a limiting plate and 11, a limiting column are arranged.

Detailed Description

In order to more clearly illustrate the technical solution of the present invention, the following provides a further description of the present invention with reference to the accompanying drawings, and obviously, the following described drawings are only one embodiment of the present invention, and for those skilled in the art, other embodiments can be obtained according to the drawings and the embodiment without any creative work, and all belong to the protection scope of the present invention.

As shown in fig. 1 to 3, the utility model discloses mainly constitute by blade 1 and sword strip 9, blade 1's blade upper end lateral wall intermediate position welding installation fixed column 3, fixed column 3 wholly is inside hollow telescopic structure, the flexible post 5 of the inside nested formula installation of fixed column 3, be connected through spring 4 between the inside cavity bottom surface of fixed column 3 and the flexible post 5 end, fixed column 3 and flexible post 5 and blade 1 coaxial arrangement.

In order to realize the connection mode of axial telescopic sliding circumferential relative fixation between the fixed column 3 and the telescopic column 5, the side wall of the fixed column 3 is provided with a sliding groove 7, the side wall of the tail end of the telescopic column 5 is welded with a sliding block 8, and the sliding block 8 is arranged inside the sliding groove 7 in a matching manner.

In order to enable the telescopic column 5 to be installed on the cutter bar 9, the side wall of the head end of the telescopic column 5 is provided with a thread 6, a screw hole is formed in the cutter bar 9, and the telescopic column 5 is installed in the screw hole formed in the cutter bar 9 through the thread 6 in a matched mode.

In order to realize positioning after the integral installation of the blade 1 is completed, a clamping groove 2 is arranged on the

blade

1, 2 limiting plates 10 which are vertically paired are welded and installed on the blade bar 9 and are called as a group, a limiting column 11 is welded and installed between the single group of limiting plates 10, the limiting column 11 is clamped in the clamping groove 2 under the installation working condition, and the blade 1 is installed between the single group of 2 limiting plates 10 in a matched mode.

The utility model discloses when the installation, at first manual 2 to 3 buckles in the screw thread that will stretch out and draw in the sword strip 9 and set up, back handheld blade 1 is to the reverse application of force of 5 precessions of flexible post and rotate, screw thread 6 of 5 head ends of flexible post is whole to be twisted in the screw thread that sets up on the sword strip 9 and make blade 1 be in with limiting plate 10 parallel state, back pine hand makes blade 1 get into under the take-up of spring 4 between singly organizing 2 limiting plates 10, make draw-in

groove

2 and 11 contact cooperations of spacing post simultaneously.

The above embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, the scope of which is defined by the appended claims.
