Description
Technical field：
The utility model belongs to technical field of engineering machinery, specifically, more particularly to a kind of land leveller and its pellet type
Equipment and hitch frame and revolution holder connection device.
Background technology：
Land leveller by perching knife equipment realize road and farmland it is smooth, the various work such as scrape side slope, scrape valley.?
It needs to drive reversing frame and perching knife revolution to realize that perching knife angle of revolution adjusts to meet by rotary motion mechanism in work
Various duty requirements.There are two types of connection types with hitch frame for land leveller reversing frame and perching knife at present：When pellet type equipment,
Reversing frame is connect by guide plate, pressing plate etc. with hitch frame, and such connection type uses process in production assembly and subsequent operation
It is middle to adjust reversing frame and hitch frame axial gap, radial clearance according to the degree of wear of wearing plate, it avoids leading because gap is excessive
Reversing frame and perching knife shaking in work is caused to influence smooth precision greatly；Because reversing frame and relieving tool post itself weight is big and reversing frame and
Hitch frame centre of gyration point is not easy the features such as adjustment overlaps, and during routine use, reversing frame and perching knife are radial with hitch frame
Gap adjustment is more difficult.
Second is that rolling disc type equipment.Reversing frame is supported by rolling revolving and is connect with hitch frame, such connection type solution
Determined the problem of needing during client's use to adjust axial gap and radial clearance according to abrasion condition demand, but cost compared with
It is high.
Invention content：
In order to solve existing for traditional tray formula equipment in the prior art between reversing frame and perching knife and hitch frame radial direction
The disadvantage of gap and axial gap adjustment difficulty, the utility model provide a kind of land leveller and its pallet being different from the prior art

Specific implementation mode：
Below by specific embodiment and in conjunction with attached drawing, the utility model is described in further detail.
Embodiment 1：
As shown in Figs. 1-3, a kind of hitch frame and revolution holder connection device, including it is upper guide plate 5, lower guide plate 7, upper wear-resisting
Plate 4 and lower wearing plate 8, the upper wearing plate 4 are connect with upper guide plate 5, and lower guide plate 7 is connect with lower wearing plate 8, it is described on lead
It is equipped with to plate 5 and the connection of lower guide plate 7 and between upper guide plate 5 and lower guide plate 7 adjust pad 6；The upper wearing plate 4 passes through
Positioning pin I 3 and screw I 11 are connect with upper guide plate 5, and lower wearing plate 8 passes through positioning pin II 9 and screw II 12 and lower guide plate 7
Connection.
Embodiment 2：
A kind of pellet type equipment, including hitch frame 1, reversing frame 2 and rotary motion mechanism 17, the hitch frame 1 with
Above-mentioned hitch frame and revolution holder connection device are equipped between reversing frame 2；The setting of reversing frame 2 hitch frame 1 and lower guide plate 7 it
Between, upper wearing plate 4 and lower wearing plate 8 are arranged between reversing frame 2 and upper guide plate 5 and lower guide plate 7 again；Rotary motion mechanism
17 driving reversing frames 2 realize the opposite rotary motion with hitch frame 1.
Embodiment 3：
As in Figure 3-5, a kind of pellet type equipment, the upper guide plate 5 are welded on hitch frame 1, lower guide plate 7
Pass through bolt I 10 and adjust pad 6 and 5 assembly connection of upper guide plate.Other parts are same as Example 2.
As shown in fig. 6, the upper guide plate 5 there are three being set on hitch frame 1 or more, it is fixed that lower guide plate 7 is machined with several
It position pin shaft hole 20, positioning screw hole 21 and is fixedly connected with bolt hole 19 with upper guide plate 5.
Upper guide plate 5 is passed through to assemble bolt I 10 from lower guide plate 7 when the present embodiment is installed, when in use according to operating mode need
It asks, rotary motion mechanism 17 drives the face that slides up and down of the inner ring of reversing frame 2 to be slided relatively with upper wearing plate 4 and lower wearing plate 8
The adjustment of 18 angle of revolution of perching knife is realized in revolution；Upper wearing plate 4 and lower wearing plate 8 limitation reversing frame 2 and hitch frame 1 simultaneously
It is axially moved；Using after a certain period of time, lead to reversing frame 2 and traction after centainly wearing occur in upper wearing plate 4 and lower wearing plate 8
It when axial gap, the radial clearance of frame 1 are excessive, unclamp bolt I 10, reduce adjust pad 6, adjust axial gap and tighten spiral shell again
Bolt I 10, because the face that slides up and down of 2 inner ring of reversing frame is that inclined-plane and upper wearing plate 4 and lower wearing plate 8 are slidably matched with its inclined-plane,
Therefore reversing frame 2 and 8 radial clearance synchronous adjustment of upper wearing plate 4 and lower wearing plate are realized while axial gap adjustment.
Embodiment 4：
As is seen in figs 7-10, a kind of pellet type equipment, the upper guide plate 5 and hitch frame 1 are fabricated construction, on
Guide plate 5 and lower guide plate 7 pass through bolt II 13 and nut II 14 and 1 assembly connection of hitch frame, hitch frame 1 and upper guide plate 5
Also connected by bolt III 15 and nut III 16.Other parts are same as Example 2.
Lower guide plate 7, upper guide plate 5 limit the axial movement of reversing frame 2, lower guiding by bolt II 13, nut II 14
Plate 7, upper guide plate 5 limit the radial motion of reversing frame 2 by bolt III 15 and nut III 16.
The present embodiment production installation when, first pass through guide plate 5, bolt III 15 and nut III 16 adjust reversing frame 2 with
The radial clearance of hitch frame 1, then adjusted by lower guide plate 7, upper guide plate 5 and bolt II 13, nut II 14, adjust pad 6
The axial gap of reversing frame 2.
The utility model after a certain period of use time, causes back after centainly wearing occur in upper wearing plate 4 and lower wearing plate 8
When pivoted frame 2, the axial gap of hitch frame 1, radial clearance are excessive, nut II 14 unclamped, reduce adjust pad 6, between adjustment axial direction
Gap simultaneously tightens nut II 14 again, because the face that slides up and down of 2 inner ring of reversing frame is inclined-plane and upper wearing plate 4 and lower wearing plate 8 and its
Inclined-plane is slidably matched, therefore realizes reversing frame 2 and upper wearing plate 4 and lower 8 radial clearance of wearing plate while axial gap adjustment
Synchronous adjustment no longer needs to the adjustment that radial clearance is realized by the adjustment of bolt III 15 and nut III 16, this diameter during use
To gap adjustment, only when producing assembly, adjustment is primary, and method is simple.
Embodiment 5：
A kind of land leveller, the land leveller are equipped with above-mentioned pellet type equipment.
