Abstract
The invention discloses a plug seedling taking mechanism with planetary gear trains of eccentric circular gears and non-circular gears. A central non-circular gear in a gearbox is fixed on a sprocket wheel box and respectively meshed with an upper eccentric circular gear and a lower eccentric circular gear; the upper eccentric circular gear is meshed with an upper planetary non-circular gear; the lower eccentric circular gear is meshed with a lower planetary non-circular gear; and initial mounting positions of five long gear shafts are positioned on the same straight line. A fixed plate is fixedly connected to one end of each seedling pushing rod, which extends out of a planting arm housing; one end of two rotating sheets is respectively hinged to the two sides of the fixed plate, and the other ends of the two rotating sheets are respectively and fixedly connected with one end of respective seedling taking sheets; a V-shaped seedling pushing claw is fixedly connected to the end of the seedling pushing rod, which extends out of the planting arm housing; and the middle parts of the seedling taking sheets are embedded in two end grooves of the V-shaped seedling pushing claw, so as to enable conicity identical with that of rice seedlings to be formed at the other ends of the seedling taking sheets. If the gearbox rotates a circle, the seedlings can be taken and transplanted for two times, so that the work efficiency is relatively high; and the plug seedling taking mechanism has the advantages of simple structure, small volume, light weight and little vibration.
Description
Technical field
The present invention relates to agricultural machinery, especially relate to a kind of off-centre operation-non-circular gear planetary gear system cave dish seedling seedling picking mechanism.
Background technology
At present, potted tray seedling transplanter both domestic and external all be with automanual be main, semi-automatic potted tray seedling transplanter leans on the artificial seedling of feeding, operating efficiency is not high, when planting speed is higher, leaks seedling, missing seedling rate increases greatly.And automatically potted tray seedling transplanter has and gives seedling automatically, gets seedling, comparatively automation and laborsavingization, high efficiency.
Though automatic potted tray seedling transplanter structure relative complex, in today that science and technology is maked rapid progress, automatic potted tray seedling transplanter will be a transplanter main development tendency from now on.If on semi-automatic potted tray seedling transplanter, loading onto this, to overlap automatic seedling picking mechanism be exactly automatic potted tray seedling transplanter structure.If this cover mechanism of soil property softer (like paddy field, field, lake region, marshland) is exactly the full-automatic potted tray seedling transplanter of a cover, is exactly a full-automatic process from getting seedling to the seedling of planting.
Summary of the invention
The purpose of this invention is to provide a kind of off-centre operation-non-circular gear planetary gear system cave dish seedling seedling picking mechanism, the physical dimension of this mechanism is less relatively, and structure is simple relatively, vibrates also less.
In order to achieve the above object, the technical scheme of the present invention's employing is:
The drive sprocket that the present invention is fixed in chain-wheel box on the power transmission shaft is connected with center sprocket wheel on being fixed in central shaft through chain, and it is affixed that central shaft stretches out chain-wheel box outer an end and gear-box; The planetary wheel mechanism of upper and lower symmetrical structure is installed in the gear-box, stretch out be equipped with respectively on the outer upper planet wheel shaft of gear-box, the lower planet wheel shaft the identical upper transplanting arm member of structure and under get the seedling arm member; Center non-circular gear in gear-box is fixed on a side of chain-wheel box through flange; The center non-circular gear respectively be fixed in jackshaft on last eccentric gear be meshed with the following eccentric gear that is fixed in down on the jackshaft; Last eccentric gear is meshed with upper planet non-circular gear on being fixed in the upper planet wheel shaft, and following eccentric gear is meshed with lower planet non-circular gear on being fixed in the lower planet wheel shaft; The major axis of the upper planet non-circular gear in the gear-box, last eccentric gear, center non-circular gear, following eccentric gear and lower planet non-circular gear is located along the same line in initial installation site.The identical upper transplanting arm member of described structure with under get the seedling arm member, include two and get the seedling sheet, seedling-pushing rod, spring, cam, shift fork is got the seedling arm housing, pushes away the seedling pawl, two rotatable lamellas; In getting the seedling arm housing; Seedling-pushing rod is installed in the axle sleeve; One end of seedling-pushing rod stretches out outside the transplant arm housing, and cam is installed on the planet axis, cam can with shift fork one end in contact that is installed on the declutch shift shaft; The other end of shift fork embeds in the spring base groove of seedling-pushing rod rear end, and the spring base of seedling-pushing rod rear end is in the driving of shift fork and be enclosed within the spring action in the seedling-pushing rod and make seedling-pushing rod do back and forth movement; Fixed head is fixed in seedling-pushing rod and stretches out the outer end of transplant arm housing; One end of two rotatable lamellas is hinged on the both sides of fixed head respectively; The other end of two rotatable lamellas is affixed with an end of getting the seedling sheet separately respectively; Stretch out outer seedling-pushing rod one end of transplant arm housing and be connected with the V font and push away the seedling pawl, get seedling sheet middle part and be embedded in the V font and push away in two end slots of seedling pawl, make the other end of getting the seedling sheet form the tapering identical with pot seedling.
The center non-circular gear is fixed; Center chain wheeling driving gear case rotates; The planet non-circular gear drives the seedling arm of getting be packed in planet axis one end and does non-uniform rotation with respect to gear-box, and the absolute movement of getting the seedling arm is the resultant motion around the uniform circular motion of central shaft of non-uniform rotation and the gear-box of the relative gear-box of planet non-circular gear.Under the influence of this resultant motion, get the angle requirement of getting seedling and the seedling of planting that seedling claw in the seedling arm member satisfies cave dish seedling.
The beneficial effect that the present invention has is:
The present invention has a gear-box, and relative centre wheel has 2 groups of planetary system gear drives in the gear-box, and every group of planetary system transmission drives 1 and get the motion of seedling arm, and gear-box turns around; Realize getting seedling 2 times, 2 transplanted seedlings, operating efficiency is higher, and is simple in structure; Volume is little, and is in light weight, vibrate little, low cost of manufacture.Through the parameter of optimizing structure; Make the movement locus of getting seedling arm upper transplanting sheet cusp satisfy the angle and the movement locus requirement of automatic potted-seedling picking mechanism work; Its relative movement orbit of getting seedling sheet point can be guaranteed reliably carrying out of automatic potted-seedling picking for " shark shape ".
