Abstract
The invention discloses a cam-pushrod seedling gripping mechanism of a rice transplanting machine and relates to a novel seedling gripping mechanism of a rice transplanting machine. A seedling gripper is a four-rod mechanism, and with power provided by a pushrod-cam mechanism, the seedling gripper is driven to open and close reciprocally. The cam and the shell of a distributing and transplanting mechanism are fixedly connected; the shell of the seedling griper is fixedly connected with the shaft of the planet wheel of the distributing and transplanting mechanism; and with reasonable design of the curve of the cam, the mechanism can cooperate with the distributing and transplanting mechanism to realize seedling catching and transplanting actions. In the invention, the structure is compact, the size of the seedling gripper is reduced on the premise of ensuring the opening range of the seedling gripper, and an external spring is convenient to replace so as to regulate the gripping force of the seedling gripper.
Description
Technical field
The present invention relates to a kind of rice transplanter, be specifically related to the seedling clamp mechanism that rice trans-planter separate is plugged in device.
Background technology
The rice shoot pick-up part of the rice transplanter that sell current domestic and international market mainly contains transplant arm and seedling presss from both sides two kinds.Transplant arm is many to be made up of plane cam, shift fork, transplanting rod and spring.This version is simple relatively, but the problem that the seedling concluding time lags behind or shifts to an earlier date appears pushing away in the variation that can not adapt to operating rate easily.This problem occurs and mainly be being decided by that the cam curve concluding time is decided by the rigidity of spring, and spring is changed difficulty because push away the seedling time started.The seedling clamp mechanism is because moving component is more, and condition of work is abominable, and problems such as job insecurity in the course of the work easily occur wearing and tearing fast.
Summary of the invention
The object of the present invention is to provide a kind of seedling folder that rice trans-planter separate is inserted mechanism that is suitable for, this mechanism can satisfy the job requirements of high speed rice transplanting, can provide different clamping forces by the spring seedling folder of changing different-stiffness.
In order to reach above-mentioned requirements, the technical solution used in the present invention is:
This invention comprises compositions such as curb pins seedling arm, back-moving spring, line shaft, seedling folder supporting seat, seedling folder housing, connecting rod, inside and outside seedling clamp pin axle, push rod bearing pin, push rod, sliding sleeve, cam, housing end plug.The seedling folder is made up of four-bar mechanism and cam follower mechanism, and both sides folder seedling arm galianconism is identical with the both sides length of connecting rod, can directly drive the four-bar mechanism action by push rod.Use the external back-moving spring, be convenient to spring and change.
The major advantage of this invention is:
Seedling clamping structure compactness can satisfy the requirement of transplanting mechanism miniaturization; It is terminal that seedling folder main motion parts concentrates on the seedling folder, away from seedling folder working position, helps improving seedling folder working life; The external back-moving spring is convenient to change, and different clamping force and seedling folder closing speeds can be provided, and is adapted to different operating rates; Back-moving spring is arranged between two seedling jig arm, make connecting rod with the active force between the bearing pin all the time in same direction, avoided alternate load can reduce wearing and tearing, and reduced seedling folder total length.
Description of drawings:
Figure 1 shows that seedling folder front view;
Figure 2 shows that seedling folder A-A direction cutaway view;
Figure 3 shows that seedling folder shaft portion B is to vertical view.
Specific embodiments:
Below operation principle of the present invention and thin bilge construction are described.The seedling folder mainly is made up of four-bar mechanism and cam mechanism.Seedling folder cam (16) is connected on the seedling folder supporting seat (6) by spline and check ring.Seedling folder housing (7) is inboard to be supported in seedling folder supporting seat by ball bearing (4), and the outside connects firmly with cam line shaft (5) by housing end plug (18) and nut (17).Cam is with the motion of transplanting mechanism housing, and the seedling folder is whole with the line shaft motion, makes the seedling folder relatively rotate with cam.Outer seedling jig arm (1), interior seedling jig arm (2), connecting rod (9), seedling clamp pin axle (10,11,12) and bearing pin screw (15) have been formed seedling folder four-bar mechanism.The seedling folder relatively rotates with cam, and cam is in upward stroke, and cam promotes push rod (13) and stretches out, and acts on four-bar mechanism by push rod bearing pin (11) the seedling folder is opened.Cam is by after the top dead centre, and seedling is clipped under the effect of back-moving spring (3) and gets back to clamped condition.
By the installation site of cam curve and seedling folder with respect to the transplanting mechanism housing rationally is set, the seedling folder can effectively be finished the opening and closing action in seedling taking, the rice transplanting process.The present invention is applicable to the planet circular system transplanting mechanism, connects firmly with transplanting mechanism if in addition seedling is pressed from both sides housing, and seedling folder supporting seat is imported as power, and the present invention can also be applicable to the crank rocker transplanting mechanism.
Claims (4)
1. a rice transplanter seedling clamp mechanism holds (4), line shaft (5), seedling folder supporting seat (6), seedling folder housing (7), sliding sleeve end cap (8), connecting rod (9), interior seedling clamp pin axle (10), push rod bearing pin (11), outer seedling clamp pin axle (12), push rod (13), sliding sleeve (14), bearing pin screw (15), cam (16), nut (17), housing end plug (18) and other connection securing members by curb pins seedling arm (1,2), back-moving spring (3), seeding gripping shaft and forms.It is characterized in that: cam and transplanting mechanism housing connect firmly, and seedling folder housing rotates with line shaft, and cam promotes the push rod action and promotes seedling folder four-bar mechanism, realize the opening and closing movement of seedling folder.
2. according to the described cam follower seedling of claim 1 clamp mechanism, its architectural feature is: seedling folder cam connects firmly with the transplanting mechanism housing by spline, seedling folder housing connects firmly with line shaft, four-bar mechanism both sides connecting rods (9) equal in length, both sides folder seedling arm (1,2) galianconism equal in length.The forearm that folder seedling arm (1,2) has two symmetries, profile is a U-shaped, two forearms of folder seedling arm press from both sides housing (7) both sides from seedling to be passed through, and has avoided the interference of seedling folder housing to the motion of folder seedling arm.
3. cam follower seedling clamp mechanism according to claim 1, its architectural feature is: seedling folder back-moving spring is arranged between the two folder seedling brachium arms.
4. according to claim 1,2 described cam follower seedling clamp mechanisms, its architectural feature is: the seedling folder adopts cam follower mechanism that power is provided, the folder seedling same cam follower of arm rotating shaft (13) center line is in same plane, the same cam of cam follower center line (16) axis is in same plane, two planes are vertical mutually, and cam is arranged on folder seedling brachium arm one side.Can increase parts such as roller, steel ball to reduce friction at cam and push rod contact site.
