Abstract
The utility model discloses a quick-change device for driven type tillage implements. The lower end of a side panel of the device is provided with a mounting hole. A bearing seat is arranged in the hole. The outer margin of the bearing seat and the side panel are connected by screws. Cutter shafts are arranged in the bearing in the bearing seat. When a working part needs to be replaced, a connecting bolt between a left shaft head and a first coupling from left is loosed, a connecting bolt of a right shaft head and a first coupling from the right is loosed, and a connecting bolt between the bearing seat and the left side panel is loosed. Therefore, the replacement of the lift movement of the left shaft head is realized.
Description
A kind of tillage implement, the particularly quick replacement device of the cutter shaft of powder actuated tillage implement.
Cutter shaft is various tillage implements, as rotovator, drives rake, the critical piece of disk plow etc.The workpiece that is used for soil cultivation is housed on the cutter shaft, as Rotary tillage blade, rake teeth or cultivation disk.Cutter shaft can be the axis of the not segmentation in the full working width, also can be to adopt the bamboo joint type combination cutter shaft that is combined by the short joint of plurality of sections.In the ordinary course of things, cutter shaft is mounted in the bearing, and bearing is contained on the side plate of facility both sides.There is one also to have gear or sprocket wheel in the biside plate, drives power with input.This structure must be unloaded lower side panel and gear earlier as changing cutter shaft, perhaps sprocket wheel, and relevant sealing, dust guard, thereby change very trouble.
The purpose of this utility model provides a kind of quick replacement device of cutter shaft, promptly only need remove the parts of cutter shaft one end when changing cutter shaft, moves the joint that needs to change and gets final product.
Concrete structure of the present utility model is, cutter shaft is that three parts are formed, and two ends are respectively spindle noses.Spindle nose by transmission case one side comprises that gear or sprocket wheel are to import power into.The spindle nose of opposite side comprises bearing, bearing block.Two spindle noses are bearing in respectively on the side plate of facility both sides.Have the spindle nose that power imports gear or sprocket wheel one end into, its bearing installation method is with common identical.Not with an end of gear or sprocket wheel, its bearing is installed on the bearing block, and bearing block can outwards move relative to side plate.The cutter shaft mid portion can be a bearing, also the bamboo joint type built-up shaft that can be made up of 2-10 section joint.On the axle in the middle of the farming workpiece is positioned on, form the workpiece group.Also a spot of workpiece can be installed on the spindle nose of two ends in case of necessity.Two spindle noses of cutter shaft are connected with jackshaft with bolt respectively.Flange and groove with its end during connection are felt relieved, to guarantee the precision and the intensity of axle.When needs dismantlement work parts group, as long as take off the set bolt at its two ends, unclamp the set bolt of bearing block and side plate simultaneously, with this bearing block together with bearing, spindle nose and other sealing, dust guard moves together laterally.When amount of movement surpasses the twice of bourrelet length between spindle nose and the workpiece group, workpiece group and two ends spindle nose can be separated.Like this, needn't dismantle the replacing that bearing, gear or sprocket wheel and sealing and dustproof annex just can be realized the workpiece group from spindle nose.
When having individual component to change in the workpiece group, its substitute mode is same as described above.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
Below in conjunction with accompanying drawing the utility model is elaborated.
Accompanying drawing is the structure of the cutter shaft quick replacement device that adopts on the driven disk plow.Right spindle nose 2 is connected with bolt respectively with the jackshaft of left spindle nose 1 and 1-10 nodal axisn joint composition, constitutes the bamboo joint type cutter shaft.On joint in the middle of each, be equipped with and the farming disk 4 of middle joint with quantity.On the spindle nose of a left side cultivation disk is housed also.Left side spindle nose is bearing on the bearing block 6 by bearing 5, and the flange of bearing block 6 is positioned on the outside (left side) of facility left plate 7.Bearing block is located by external diameter.The oil sealing 9 of a pair of reverse installation is equipped with in the inside that is installed in the oil seal seat 8 on bearing block the right.The external diameter of oil seal seat is equal to or less than the diameter of bearing block installing hole.Bearing is located by the oil sealing left end.
When needs are changed whole workpiece group, unclamp a left spindle nose and a left side and play connecting bolt between first joint.Unclamp right spindle nose and the right connecting bolt that plays first joint.Unclamp the connecting bolt between bearing block and the left plate, with bearing block 6 related bearings 5, part such as left side spindle nose 1, oil seal seat 8 and oil sealing 9 etc. in addition together move to left, when amount of movement surpasses the twice of bourrelet 13 height between left and right sides spindle nose and the jackshaft, whole workpiece group can be taken off.
When some cultivation disk, damage as disk 4, when needing to change, unclamp the joint 11 at this disk place and the connecting bolt between its left side joint.Unclamp the connecting bolt between bearing block 6 and the left plate 7, bearing block 6 and incidental part in addition move to left.When amount of movement surpasses the thickness that locating flange length between the joint adds cultivation disk, unclamp the set bolt between the flange of cultivation disk and joint then, change this cutterhead.
Claims (2)
1, a kind of quick replacement device of driving type tillage implement cutter shaft, feature of the present utility model is that the lower end of side plate 7 has an installing hole 10, one bearing block 6 is housed in the hole, the flange 14 of bearing block is connected with bolt with side plate, cutter shaft 3 is contained in the bearing in the bearing block 6, and the inboard distance to this side shaft head and joint connector 12 of side plate should be greater than the twice of bourrelet 13 height of joint.
2, device according to claim 1 is characterized in that oil seal seat 8 is equipped with in the inboard of bearing block 6, and the maximum outside diameter of oil seal seat is equal to or less than the diameter of bearing block installing hole 10.
