Abstract
The utility model discloses a clutch device used by a single-ridge stubble cleaner towed by a tractor, which comprises a cutter roller shaft, a bearing, a big chain wheel, and a main cam sleeve, and is characterized in that one end of a pull rod used by a clutch hangs on a handspike locating seat on the handle of the tractor; the other end of the pull rod is connected with a secondary cam sleeve through a connecting seat, a small lever and a shifting fork; with the help of a compression spring, the main cam sleeve and the secondary cam sleeve engage and disengage so as to realize the engaging and disengaging operation of the clutch; and the main cam sleeve, the secondary cam sleeve and the compression spring are all arranged in a housing. The utility model has the advantages of resistance to rainwater as well as mud and weed invasion, full lubrication of the clutch, antirust performance, simple structure, convenient operation, flexibility, reliability, low failure rate, small workload of maintenance, long service life, high value for popularization and application, and good market prospects.
Description
Technical field
The utility model relates to a kind of agricultural machinery, more particularly, relates to a kind of stubble cleaner annex.
Background technology
Eliminate the stubble in the ground, this is a job must doing before the farming.The clutch of single ridge stubble cleaner of existing tractor-drawn all is mounted on belt pulley or the final drive shaft, its a whole set of arrangement of clutch is exposed externally, therefore in the stubble-cleaning operating process, on clutch, can pile up a lot of earth, twine a lot of faggots, make the secondary tooth embedding of clutch violate card frequently, be not inseparable be exactly not close, need often cleaning, bring a lot of troubles to production operation, have a strong impact on the raising of operating efficiency, it is improper that another shortcoming is that the operation draw rod positions of clutch is provided with, far away from operating personnel's distance, must stride back or push on and stretch forward, just can contact the operation hand lever, carry out clutch operating, inconvenience is arranged more, influence operating efficiency and work quality.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of new construction list ridge stubble cleaner arrangement of clutch is provided.
The utility model is the improvement to existing stubble cleaner, its scheme is that a bearing is housed on sprocket wheel, make it the rotation of when inoperative, floating, the cardinal teeth build-in fixes on the end face of hinge wheel, secondary tooth is inlaid in the spline position with the same tool roller axis of hinge wheel, and secondary tooth is embedded with the compression spring, and has clamp nut to be fixed on the end face of tool roller axis, the clutch fork is contained on the cover plate of housing, and cardinal teeth embedding, secondary tooth embedding, fork, spring, spring base all are included in the housing.
A kind of single ridge stubble cleaner arrangement of clutch, comprise cardinal teeth embedding on tool roller axis, bearing, hinge wheel, the hinge wheel, it is characterized in that, clutch hangs on the hand lever positioning seat on the tractor handle with pull bar one end, the pull bar other end is connected with secondary tooth embedding through Connection Block, little moving rod, fork, by the compression spring, realize cardinal teeth embedding, secondary tooth embedding clutch, realize clutch from, closing operation; Cardinal teeth embedding, secondary tooth embedding, compression spring all are located in the housing; Housing is fixed on the chain box body, and housing and chain box body form unified machine chamber, and are provided with lubricating oil in the chamber, obtain sufficient lubrication.
Advantage of the present utility model is, clutch pull rod one end is located on the hand lever positioning seat on the handle of hand tractor, and is easy to operate, clutch Outside is provided with housing, contains its transmission position, makes clutch be not made of salt, and can stop muddy, faggot intrusion, clutch can obtain sufficient lubrication, be difficult for corrosion, this utility model is simple in structure, and is easy to operate, flexibly, reliably, fault rate is low, and maintenance workload is little, long service life.
Description of drawings
Fig. 1 is the utility model working state schematic representation.
Fig. 2 is the utility model structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is made detailed description further.
As shown in Figure 1, hand tractor 1 is preceding, the pulling stubble cleaner, be fixed with clutch 5 on the stubble cleaner chain casing 4, there is stubble-cleaning rotor 6 in rotation, to advance, land wheel 7 is supported on ground, pull bar 8 one ends of clutch hang on the hand lever positioning seat 2, hand lever positioning seat 2 be provided with from, close two gears and put, the other end of pull bar 8 is by Connection Block 14, little moving rod 13, clutch fork 12 makes cardinal teeth embedding 9 contact with secondary tooth embedding 10 or breaks away from, the duty of decision stubble cleaner, its cover plate 11, protective cover 18,20 protective actions of housing prevent earth, faggot enters clutch, spring base 15, spring shim 16, clamp nut 17, compression spring 19 is in order to the location.One of feature of the present utility model is with cardinal teeth embedding 9, secondary tooth embedding 10, fork 12, compression spring 19, spring base 15 is located in the housing 20, the end that fork 12 slides is contained in the groove of secondary tooth embedding 10, the other end of fork 12 exposes the top of cover plate 11, it is connected with little moving rod 13, little moving rod 13 ends are connected with pull bar 8 by Connection Block 14, pull bar 8 is connected with hand behaviour bar 3, be contained on the hand behaviour bar positioning seat 2, positioning seat 2 usefulness clips are fixed on hand tractor 1 handgrip, hand lever positioning seat 2 be provided with from, close two gears, hand lever 3 is moved in front and back, can finish clutch action, realizes whether stubble-cleaning is operated.
This stubble cleaner can not obtain sufficient lubrication outside with clutch is exposed, is not made of salt, humidity, do not have in silt particle, faggot go into, so fault rate is low, and long service life has highly application value, and has good market prospects.
