Abstract
The utility model discloses a rice transplanter planting mechanism planting arm. A planting arm drive axis in a planting arm shell is provided with an initiative taper gear; a driven taper gear and a column cam are arranged on the same axis; the initiative taper gear and the driven taper gear are meshed together; the column cam, a sector gear and a roller fixed on the sector gear constitute a column cam mechanism; the sector gear is a driven piece of the cam mechanism; the sector gear is fixed on a gemel point of the planting arm shell; the gemel point is the rotary center of the sector gear; the sector gear is meshed with a rack fixed on a pushing seedling pole; a seedling needle is arranged on the planting arm shell and moves according to the planting arm shell. The utility model adopts a taper gear mechanism, the column cam mechanism and a gear rack mechanism to change the pushing seedling pole from rotary motion to disciplinarian linear reciprocating motion. The mechanism can satisfy the planting requirements of the transplanter, and adapt to transplanter at any speed work.
Description
Technical field
The utility model relates to rice transplanter, is specifically related to a kind of rice trans-planter separate and inserts mechanism's transplant arm.
Background technology
The effect of transplant arm is a device of the blanket appearance seedling on the rice transplanter seedling case being torn and is inserted into Tanaka.At present, the transplanter planting arm version of at home and abroad selling on the market is consistent with transmission principle, be specially: finish seedling pushing action jointly by plane cam, shift fork, transplanting rod and spring, its version is simple, but can not adapt to different rotating speeds, when particularly operating speed changes greatly, the seedling concluding time often occur pushing away in advance or hysteresis, this is that the length that pushes away the seedling time then is decided by the rigidity of spring owing to push away the profile that the time started of seedling is decided by cam.Ordinary circumstance can not changed spring, so rice transplanter can only operation in certain velocity interval, and is poor to the adaptive capacity of speed.
Summary of the invention
The purpose of this utility model provides a kind of rice trans-planter separate and inserts mechanism's transplant arm, and this mechanism can satisfy the rice transplanting requirement that this mechanism of rice transplanting requirement can satisfy rice transplanter, and can adapt to the operation under the transplanting machine at any rotating speed.
In order to achieve the above object, the technical solution adopted in the utility model is:
Initiatively conical gear is housed on the transplant arm driving shaft in the transplant arm housing, driven bevel gear and cylindrical cam all are contained on the same axle, initiatively conical gear and driven bevel gear are meshed, cylindrical cam, sector gear and the roller that is fixed on the sector gear are formed cylindrical cam mechanism, sector gear is a cam follower, sector gear is fixed on the hinge point on the transplant arm housing, hinge point is the center of rotation of sector gear, sector gear is meshed with tooth bar on being fixed on transplanting rod, the seedling pin is contained on the transplant arm housing, moves with the transplant arm housing.
The radius of sector gear is that the center of rotation of sector gear is to 1.5～2.5 times of the center of rotation distance of roller.
Initiatively the gearratio of conical gear and driven bevel gear is 1: 1
Adopt bevel gears, cylindrical cam mechanism and pinion and rack, rotatablely moving of transplant arm driving shaft is transformed into the regular straight reciprocating motion of transplanting rod.
The beneficial effect that the utlity model has is: this mechanism can satisfy the rice transplanting requirement of rice transplanter, and can adapt to the operation under the transplanting machine at any rotating speed.
Description of drawings
Accompanying drawing is a structural principle schematic diagram of the present utility model.
Among the figure: 1, transplant arm driving shaft, 2, conical gear initiatively, 3, driven bevel gear, 4, cylindrical cam, 5, roller, 6, axle, 7, tooth bar, 8, sector gear, 9, hinge point, 10, transplanting rod, 11, the transplant arm housing, 12, the seedling pin.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in drawings, initiatively conical gear 2 is housed on the transplant arm driving shaft 1 of the utility model in transplant arm housing 11, driven bevel gear 3 and cylindrical cam 4 all are contained on the same axle 6, initiatively conical gear 2 and driven bevel gear 3 are meshed, cylindrical cam 4, sector gear 8 and the roller 5 that is fixed on the sector gear 8 are formed cylindrical cam mechanism, sector gear 8 is a cam follower, sector gear 8 is fixed on the hinge point 9 on the transplant arm housing 11, hinge point 9 is the center of rotation of sector gear 8, sector gear 8 is meshed with tooth bar 7 on being fixed on transplanting rod 10, seedling pin 12 is contained on the transplant arm housing 11, with 11 motions of transplant arm housing.
The radius of sector gear 8 is that the center of rotation of sector gear 8 is to 1.5～2.5 times of the center of rotation distance of roller 5.Initiatively the gearratio of conical gear 2 and driven bevel gear 3 is 1: 1.
Operation principle of the present utility model is as follows:
As shown in drawings, during the utility model work, transplant arm driving shaft 1 rotates, be meshed by active conical gear 2 and driven bevel gear 3, vertical with it axle 6 is passed in the motion of transplant arm driving shaft 1, make cylindrical cam 4 around axle 6 rotations, the profile basis of cylindrical cam 4 pushes away the technological requirement (displacement, speed and the acceleration that comprise transplanting rod) of seedling and the amplification ratio of cam mechanism (being that hinge point 9 is to the distance at roller 5 centers and the ratio of the radius of sector gear 8) designs the requirement that makes it to realize pushing away the seedling characteristics of motion He satisfy pressure angle.Cylindrical cam 4, sector gear 8 and the roller 5 that is fixed on the sector gear 8 are formed cylindrical cam mechanism, sector gear 8 is a cam follower, sector gear 8 is fixed on the hinge point 9 on the transplant arm housing 11, hinge point 9 is the center of rotation of sector gear 8, sector gear 8 is meshed with tooth bar 7 on being fixed on transplanting rod 10, thereby the linear reciprocation that rotatablely moving of cylindrical cam 4 is changed into transplanting rod 10 clocklike pushes away the seedling motion, and rice shoot on the seedling pin 12 is pushed Tanaka.
Above-mentioned embodiment is used for the utility model of explaining; rather than the utility model limited; in the protection domain of spirit of the present utility model and claim, any modification and change to the utility model is made all fall into protection domain of the present utility model.
