Description
Technical field
A kind of pneumatic drum type fine seed-metering machine of wheat is the utility model is related to, belongs to technical field of agricultural mechanical equipment.
Background technology
Wheat is one of main grain ration of our people, and irreplaceable status is occupied in diet structure, and very heavy
The commodity food wanted and trade grain.Rationally the sowing of smart amount can provide better growing conditions for wheat and improve wheat to soil
The utilization ratio of earth nutrition, moisture and sunlight, coordinates wheat individual and group relation, makes the wheat percentage of earbearing tiller high, and grain is more, full,
Realize the good quality and high output of wheat.
In actual production, the feed mechanism for seed for sowing wheat uses external recessing more, and external recessing is not belonging to
Precise seeder, seed cannot be sown into soil according to rational locus, and external recessing causes there are pulsating nature
Easily be short of seedling disconnected ridge in seeding process, or generation wheat seeding is crowded, greatly reduces land resources utilization rate.
The content of the invention
The utility model aim is to provide a kind of pneumatic drum type fine seed-metering machine of wheat, realizes uniform wheat, essence
Heavy seeding kind, the apparatus structure is simple, efficient, considerably increases land resources utilization rate.
The utility model pneumatic drum type fine seed-metering machine of wheat includes rack, transmission device, dispenser, negative pressure wind
Machine；
The transmission device includes motor, air-suction seed metering device axis, axis, roller, chain wheel I, support arm；Support arm passes through aspiration
Feed mechanism for seed axis, axis are fixed in rack, and air-suction seed metering device axis is quill shaft, and its one end is connected with negative-pressure air fan, and the other end passes through
Bearing is connected with roller one end, and the roller other end is sleeved on axis, and chain wheel I is sleeved on axis and is connected with roller, and chain wheel I passes through
Chain is connected with the chain wheel II on motor output shaft, and pocket is provided with outer surface of cylinder；
The dispenser includes seeds discharging box, leads kind of a plate, clear kind brush, seed cleaning sheet；Seeds discharging box is fixed on rolling by support arm
The top of cylinder, clear brush of planting is fixedly mounted on seeds discharging box, and above roller, seed cleaning sheet is installed on the seeds discharging box back lower place, and
Positioned at roller rear, more than one piece of the inside led kind of plate and be installed on seeds discharging box, and the gap led between kind of plate is opposite with pocket
Should.
The roller is arranged on the inside of support arm by the limitation unit on support arm.
The chain wheel I is connected with roller by bolt.
The air-suction seed metering device axis connection negative-pressure air fan to right end cover is hollow shaft, and remainder is solid shafting.
The seeding box shaped is semicircle.
The shape of said pocket is half capsule shape, and surrounding is rounded down, and the opening that pocket is located at drum inside is sucker.
Kind of the plate of leading is that vertical section is in reverse V-shaped structure, and bottom size is less than the major axis dimension of wheat seed.
The sprocket wheel is boss sprocket wheel.
The operation principle of the utility model：
Motor, negative-pressure air fan are first turned on, under the driving of motor, sprocket wheel, roller and seeds discharging box rotate, negative-pressure air fan production
Raw negative pressure is delivered to drums inside by air-suction seed metering device axis, and drums inside produces negative pressure, causes roller is inside and outside to produce air pressure
Difference, seed fall leading on kind of plate in seeds discharging box from the external world, and in the case where leading kind of plate and being oriented to, seed is by long axis direction parallel to rotary drum radial
Arranged to direction.Seed is fallen into pocket under the frictional force of self gravitation and roller, the sucker absorption of quilt intraocular, and with
Roller rotation, when seed rotates to Qing Zhong areas, clear hairbrush of planting is by the seed and the circumocular kind of nest in pocket more than one
Son clears, it is ensured that leaves a seed in each pocket, when pocket goes to Xie Zhong areas, seed in pocket is under sucker suction gram
Self gravitation and centrifugal force are taken, is adsorbed in pocket until rotating to area of charging seed, in area of charging seed, seed is in self gravitation and clear kind
Overcome the adsorption capacity of sucker to depart from pocket under the thrust of piece, fall into soil, complete whole seeding process.
The beneficial effects of the utility model are：
1st, solve existing wheat feed mechanism for seed seeding is uneven, be short of seedling disconnected ridge phenomena such as.
2nd, wheat precision drilling can be achieved, save seed, improve resource utilization.
3rd, devise and lead kind of a side plate, improve kind of a speed of filling for seed, reduce leakage sowing rate.
4th, pocket is designed to half capsule shape, is easy to fill kind and clear kind.
5th, it is simple in structure, easy to operate, working stability.
