Abstract

The utility model discloses a connecting device of a rake sheet, which comprises a shell body, a connecting lug, sealing covers, a bracket, an oil seal, a bearing, a shaft sleeve, a concave-surface separating sleeve, a square shaft, a separating pipe, the rake sheet and a convex-surface separating sleeve. The shell body is installed in a circular hole under the bracket through the connecting lug; the shell body is blocked in the circular hole under the bracket through a lock sheet; the bearing is installed in the shell body; the inner ring of the bearing is installed on the excircle of the shaft sleeve; a square hole is installed in the shaft sleeve, and the square shaft is arranged in the square hole; both sides of the shell body are provided with the sealing covers; the inner side of the sealing cover is provided with the oil seal; the outer side of the sealing cover at one side of the shell body is provided with the concave-surface separating sleeve, the rake sheet is installed at the concave-surface, and the concave-surface of the concave-surface separating sleeve and the convex-surface of the separating pipe fix the rake sheet on the square shaft; the outer side of the sealing cover at the other side of the shell body is provided with the convex-surface separating sleeve, the marrow sheet is installed at the convex-surface, and the convex-surface of the convex-surface separating sleeve and the concave-surface of the separating pipe fix the rake sheet on the square shaft. The connecting device of the rake sheet solves problems that the shaft bushing is non-durable, the resistance is large, and the sandy soil easily enters the rake sheet for rake sheet connection.

Description

The coupling arrangement of blade

Technical field

The utility model belongs to a kind of coupling components of agricultural machinery, is specifically related to a kind of coupling arrangement of blade.

Background technology

At present, rake is the cultivated scarification equipment that is used for the farmland hack by tractor-drawn, and the combination connecting mode of its soil cracking member blade mainly adopts shide and iron watt to serve as rolling bearing.Its defective is: the transmission resistance is big, seals badly, easily advances soil and silt during operation between bearing shell, quickens bearing bush abrasion, and service life is short, and mu workload oil consumption is big, has wasted the energy, and operating cost rises.

Summary of the invention

The purpose of this utility model is to provide a kind of good airproof performance, rotation is flexible, resistance is little and the blade coupling arrangement of long service life.

For achieving the above object, the utility model comprises housing, connects ear, seal cover, support, oil sealing, oil nozzle, bearing, axle sleeve, concave surface spacer, square shaft, pipe, blade and convex surface spacer.Housing is by in the circular hole that connects ear and be contained in the support below, and below support in the circular hole, housing also can have fine rotation amount and axial internal clearance to locking plate with the housing retaining; Bearing is housed in the housing, and bearing inner ring is contained on the cylindrical of axle sleeve; In the axle sleeve is square hole, and square shaft is contained in the square hole; Seal cover is equipped with in the housing both sides, the axial float of seal cover rigid bearing, and oil sealing is equipped with in the seal cover inboard; The concave surface spacer is equipped with in the housing one side seal lid outside, and blade is equipped with at the concave surface place, and the concave surface of concave surface spacer and the convex surface of pipe are packed in blade on the square shaft; The convex surface spacer is equipped with in the housing opposite side seal cover outside, and blade is equipped with at the convex surface place, and the convex surface of convex surface spacer and the concave surface of pipe are packed in blade on the square shaft.

Beneficial effect

The utility model makes the blade rotary resistance fall the end owing to adopted rolling bearing and oil sealing in the installation place of blade, and power consumption is little, and housing has adopted movable the connection with support, the rolling member long service life.
