Agricultural machinery blade fixing frame

Abstract

The invention discloses a device to prevent the door closed, and particularly to a locator for positioning a sliding door. The agricultural machinery blade fixing frame includes a bottom plate and an elastic rod, and the elastic rod includes a first end, a middle part and a second end, and the first end, the middle part and the second end are connected in turn from back to front. The first end is fixed to the rear end of the bottom base through bolts, and the middle part is inclined upwards to form an elevation. The bolt includes a bolt head and a thread column, and the thread column is connected to the bottom plate by means of threaded connection, and a spring washer, a compression spring and a flat washer are orderly sheathed on the thread column between the bolt head and the bottom plate. The first end is clamped between the spring washer and the compression spring, and the second end bends downwards to form an arc structure. The disclosure overcomes the defects of inconvenient disassembly and damages to door body existing in prior art, and provides an agricultural machinery blade fixing frame which can enhance the friction of door body relative to the ground by elastic pressing.

Description

technical field [0001] The invention relates to an installation and fastening fitting used in agricultural machinery, in particular to blade fixing frames of various cutting tools in agricultural machinery. Background technique [0002] There are various cutting tools in agricultural machines, such as harvesters, lawn mowers, etc. The general structure of the cutting tools includes a rotating shaft, a rotating disc is connected to the end of the rotating shaft, and a set of blades are fixed on the rotating disc. The conventional bolt fixing method is adopted between the rotating disk and the rotating disk. [0003] However, in actual operation, the connection between the blade and the rotating disk is not firm. When starting or stopping each time, the blade will be affected by inertia, and it will deflect clockwise or counterclockwise relative to the rotating disk, so that the blade will drive the corresponding bolt to rotate. Although there is only a little deflection each...

AI Technical Summary

Problems solved by technology

[0003] However, in the actual operation process, the connection between the blade and the rotating disk is not stable

When starting or stopping every time, the blade will be affected by inertia, and it will deflect clockwise or counterclockwise relative to the rotating disk, so that the blade will drive the corresponding bolt to rotate. Although there is only a little deflection each time, it can be used for a long time. , the threaded connection between the bolt and the rotating disk will be loosened. If the blade falls off from the rotating disk during the high-speed rotation of the blade, it will cause great harm to the operator.
