Abstract
The utility model provides a seeder used for agricultural planting, which is mainly composed of an outer shell, a seed box, a soleplate, a seeding wheel, reciprocating pushrods, pushrod oriented wheels, a spring and a cam. The reciprocating pushrods and the spring are inlaid into the seeding wheel and the pushrod oriented wheel; the seeding wheel, the pushrod oriented wheels and a shaft sleeve are connected as a whole; the cam and the outer shell are connected as a whole; a nest hole is arranged on the gap where the reciprocating pushrods and the seeding wheel are glidingly matched towards the rotating direction; the nest hole is slightly larger than the seed and part of the reciprocating pushrods which are distributed on the same intervals can be rotated at 180 degrees. During the seeding process, the reciprocating pushrods start forced seed taking and seeding under the effect of the spring and the cam to improve the reliability of planting and adapt to rapid machine sowing. At the same time, through the rotation of part of the reciprocating pushrods, sowing with variable plant spacing can be achieved.
Description
Technical field
The utility model relates to a kind of agricultural seeding machine tool, especially relates to a kind of dispenser that is applicable to animal power and mechanical planting.
Background technology
Existing cave formula seeding unit all is to stamp the nest eye on seed wheel, make seed fall into the nest eye passively by gravity during seeding, when sowing minute seeds such as millet, the peripheral velocity of seed wheel surpasses the just easy leakage choosing of 0.2 meter per second and causes occurring the hole, make to produce the disconnected ridge phenomenon of being short of seedling in the future, therefore can not adapt to quick machine sowing.Distance between the formula seeding unit nest eye of existing cave is all fixed, and can not regulate, and therefore can not effectively control spacing in the rows.
Summary of the invention
The purpose of this utility model is to solve the problem that above-mentioned seeding unit exists, and provides a kind of and can adapt to sowing fast, can effectively control the seeding unit of spacing in the rows.
For achieving the above object, the utility model is mainly by seed-box, base plate, spring, push rod directive wheel, reciprocating push rod, cam, seed wheel, axle sleeve, shell and scrape kind of device and form, seed-box and scrape kind of a device and be fixed on the base plate, base plate and shell fix as one, and with the seed-box correspondence position one opening are arranged on the base plate, outer casing underpart has a sowing port, and seed wheel and push rod directive wheel are uniformly distributed with radial direction through hole respectively along the circumference; One boss along circumferential protrusion is arranged on the reciprocating push rod, and boss is the plane near the plectane place, and is slidingly matched with plectane; Cam center has a circular hole, cam be enclosed within on the axle sleeve and with the axle sleeve matched in clearance; Shell is spliced into one by two halves, and wherein half and cam combine as a whole; Seed wheel is spliced into one by the two halves that the radial section by each through hole center line is divided into, each half with its in push rod directive wheel and axle sleeve combine as a whole by plectane; The reciprocating push rod two ends penetrate respectively in the through hole of seed wheel and push rod directive wheel, and are slidingly matched with through hole on seed wheel and the push rod directive wheel, spring housing on reciprocating push rod near seed wheel one end; Seed wheel and reciprocating push rod have a brood of eye towards the matched in clearance place of seed wheel direction of rotation, the reciprocating push rod that part is spacedly distributed is Rotate 180 ° on this basis also; The inwall of outer casing bottom inwall and two sides parallel with seed wheel is pressed close to the lower half circle bottom of seed wheel and the two sides of seed wheel respectively.
This cam is by the seeding cam and get kind of a cam and be integrated, and center line and the trunnion axis of getting kind of cam are 45 ° of angles, and the center line of seeding cam and trunnion axis are 270 ° of angles, the seeding cam with get kind of cam and all be slidingly matched with push rod directive wheel inwall.
The total length of this reciprocating push rod is poor less than seed wheel exradius and radius of cam base-circle, and the length that reciprocating push rod penetrates push rod directive wheel part is poor greater than push rod directive wheel exradius and radius of cam base-circle.
Adopt the structure of reciprocating push rod and cam cooperating in the such scheme, reciprocating push rod is released seed wheel getting kind of a process cam, realize getting kind of an operation by force, improved the success rate of getting kind greatly; When seed wheel went to sowing port, cam was released seed wheel with reciprocating push rod, retracted to fast again under the acting in conjunction of spring and cam in the seed wheel, and seed is the reliable sowing port of discharging under effect of inertia.Getting kind and seeding is operable under the prerequisite that power heightens, seeding unit is being adapted to fast sow.Because two opposite faces of reciprocating push rod convex platform are the plane parallel with plectane, seed wheel is combined into by two halves again, so can be more convenient ground as required with part reciprocating push rod Rotate 180 °, the reciprocating push rod that rotates through so just can not be got kind, thereby strengthened sowing at interval, realized the requirement of multiple spacing in the rows.
