Description
Technical field
The utility model belongs to agricultural machinery, relates generally to a kind of fertilizer expelling shaft rotational power combination on the precise sowing fertilizing equipment or the arrangement of clutch that cuts off.
Background technology
At present, the rotational power of Precision Seeding machine fertilizer expelling shaft all is to be rotated by the facility land wheel, by chain be packed in that sprocket wheel transmission on the fertilizer expelling shaft finishes, owing on fertilizer expelling shaft, do not establish the driving power-off device, as long as land wheel rotates, fertilizer expelling shaft promptly rotates, and fertilizer apparatus is a fertilizer.In the actual production operation, when the Precision Seeding machine breaks away from ground to edge of a field land wheel, fertilizer apparatus has been finished edge of a field fertilising operation, because of seeding unit is positioned at the fertilizer apparatus rear portion, stop seeding operation simultaneously, make fertilising both sides, position, the edge of a field not have kind of a grain, cause fertilizer loss, and charged into chemical fertilizer in the defertilizing tube and also leak and be sprinkling upon on the soil surface of the edge of a field, increased the waste of chemical fertilizer again.
Summary of the invention
The purpose of this utility model is exactly not drive existing problem of power clutch mechanism and defective at being provided with on the fertilizer expelling shaft in the above-mentioned prior art, and design provides a kind of activation power clutch device of precision seeder fertilizing axis, reaches the purpose of saving chemical fertilizer significantly.
Basic design of the present utility model is to utilize the bearing that is packed on the fertilizer expelling shaft that the fertilizer drive sprocket that the outer face is provided with the tooth embedding is installed in rotation on the fertilizer expelling shaft; On the fertilizer expelling shaft outer surface that is positioned at fertilizer drive sprocket outside left, be provided with and drive the key tooth, the castellated disengaging pawl that has inner hole key slot can be sleeved on the fertilizer expelling shaft axially slidably, and with drive the key tooth and cooperate, with castellated disengaging pawl on fertilizer expelling shaft circumferentially, radial location, castellated disengaging pawl matches with tooth embedding on the fertilizer drive sprocket outer face; The compression spring housing is contained in and drives on the key tooth outside, and locking nut is fixed tightly on the fertilizer expelling shaft external end head, will compress spring one end and be pressed against on the end face of the castellated disengaging pawl outside axial location on fertilizer expelling shaft; The shift fork of hinge dress shift fork slide block is rack-mount swingably, and the shift fork slide block is configured in the castellated disengaging pawl annular groove; In the configuration of shift fork sidepiece the shift fork location-plate that matches with shift fork is installed, is so far constituted activation power clutch device of precision seeder fertilizing axis.
The utility model can be controlled the rotation of fertilizer expelling shaft at any time or stop, and realizes the fertilising of fertilizer apparatus or stops the operation of applying fertilizer, and has simple in structure, operation simple and convenient, uses reliable, joint fertilizer efficiency fruit outstanding feature.
