Description
Technical field
The utility model belongs to agricultural machinery technological field, relates to a kind of cam-type indenting tool.
Background technology
Indenting tool is one of important feature of hill-drop planter, and it is sowing efficiency and seeding quality that the reliability opened and closed affects hill-drop planter to a great extent; The indenting tool of current extensive use mainly contains passive type and active keying two kinds, and passive opening/closing type indenting tool is by the keying of the touch controls indenting tool with soil, and its reliability is not high, easily results in blockage and hole; Active opening/closing type indenting tool relies on self control device enforced opening and closedown, has higher reliability, and due to the defect of active opening/closing type indenting tool opening/closing system, cause and open and close insufficient or open and close excessive velocities, seed can not fully be discharged.
Utility model content
The purpose of this utility model provides a kind of cam-type indenting tool for prior art Problems existing.
A kind of cam-type indenting tool, comprise Moving plate, be arranged on Moving plate duckbilled circumferentially, described Moving plate inside is provided with wheel chamber, described duckbilled is communicated with wheel chamber, the card center of described Moving plate is provided with cam disc, described Moving plate is evenly provided with driving rod around cam disc, described driving rod is movably connected in the card of Moving plate, the card of described Moving plate is provided with the back-moving spring corresponding with driving rod, and described back-moving spring is connected with the shaft of driving rod, the open portion of described duckbilled is provided with follower lever, one end of described driving rod is connected with follower lever by connecting rod, the other end of driving rod and cam disc circular contact,
The jut of described cam disc is smoothly connected by convex outward and progressive cambered surface and forms;
Described driving rod is provided with the inner sunken face corresponding with convex outward towards the termination of cam disc;
The card of described Moving plate is provided with bearing pin, and the shaft of described driving rod is provided with bar shape trench hole, and described bearing pin is flexibly connected with slotted eye.
The utility model has following beneficial effect:
The utility model structure is simple, reliable operation, reasonable in design, cam disc is adopted to provide unlatching moment for duckbilled, enforced opening and the closedown of indenting tool is realized by driving rod mechanism carry-over moment, effectively reducing indenting tool because blocking the hole or resowing phenomenon of causing, improve sowing efficiency and quality; During the coordinating and prevent driving rod and cam disc from colliding of inner sunken face and convex outward, damage is caused to parts, progressive cambered surface makes duckbilled slowly close, seed can be made to discharge more fully, slotted eye is relative to bearing pin rectilinear motion, increase the angle that driving rod swings around bearing pin, thus increase duckbilled opening angle, enhance seeding efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model cam disc.
Embodiment
A kind of cam-type indenting tool as depicted in figs. 1 and 2, comprise Moving plate 1, be arranged on Moving plate 1 duckbilled 2 circumferentially, described Moving plate 1 inside is provided with wheel chamber, described duckbilled 2 is communicated with wheel chamber, it is characterized in that: the card center of described Moving plate 1 is provided with cam disc 3, described Moving plate 1 is evenly provided with driving rod 4 around cam disc 3, described driving rod 4 is movably connected in the card of Moving plate 1, the card of described Moving plate 1 is provided with the back-moving spring 5 corresponding with driving rod 4, and described back-moving spring 5 is connected with the shaft of driving rod 4, the open portion of described duckbilled 2 is provided with follower lever 6, one end of described driving rod 4 is connected with follower lever 6 by connecting rod 7, the other end of driving rod 4 and cam disc 3 circular contact, the jut 3-1 of described cam disc 3 is smoothly connected by convex outward 3-2 and progressive cambered surface 3-3 and forms, described driving rod 4 is provided with the inner sunken face 4-1 corresponding with convex outward 3-2 towards the termination of cam disc 3, the card of described Moving plate 1 is provided with bearing pin 8, and the shaft of described driving rod 4 is provided with bar shape trench hole 4-2, and described bearing pin 8 is flexibly connected with slotted eye 4-2.
During work, cam disc 3 keeps static, Moving plate 1 drives driving rod 4 to rotate around cam disc 3, when driving rod 4 rotates the jut 3-1 to cam disc 3, the termination of driving rod 4 and the convex outward 3-2 of jut 3-1 collide, and bar shape trench hole 4-2 moves relative to bearing pin 8 and driving rod 4 is swung around bearing pin 8, drive connecting rod 7 and follower lever 6 to move, duckbilled 2 is opened, and seed is discharged by the wheel chamber of Moving plate 1; When the termination of driving rod 4 moves to progressive cambered surface 3-3 place, under the effect of back-moving spring 5, driving rod 4 angle of oscillation reduces gradually, thus duckbilled 2 is slowly closed, and completes seeding operation.
