Description
Technical field
The utility model relates to a kind of cave dish precision seed metering device, refers in particular to a kind of magnetic drum formula precision seed metering device, and this device is applicable to the precise sowing of granule seeds such as vegetables, flowers and nursery stock.
Background technology
At the initial stage seventies, the U.S. has at first released the industrial hole plate seedling growth technology, because this technology has at a high speed, high-quality, high yield, thereby has obtained rapid popularization in other agricultural economy developed country as states such as Holland, France, Germany, Japan.The precision point sowing that key technology is a seed that the industrial hole plate seedling growth technology at first will solve because most of vegetables, the flower seed volume is little, in light weight, shape is irregular again, thereby has brought difficulty for its precise sowing.At present, dish precision seed metering device in cave has mainly adopted seeding principles such as pneumatic type, mechanical type, Electromagnetically vibrating both at home and abroad.Pneumatic precision seeder does not have specific requirement to the profile of seed, seeding accuracy is higher, but suction pipe or suction hole are easily blocked, need change suction nozzle for the variable grain seeds in size, and manufacturing cost and operation technique are had relatively high expectations: the mechanical precise seeder is simple in structure, and speed of drilling is fast, but tight to the shape requirement of seed, generally all need seed is carried out the pill processing, and wound kind of a phenomenon is arranged; Electromagnetically vibrating precise seeder utilizes the principle of electric and magnetic oscillation sorting seed, order about the oscillating plate swing of seeding unit by electromagnet, the kind grain that flows out from vibration box moves along the set trapezoidal groove of seed plate, and evenly move forward and fall in the grain tube, imported in the hole, cave by grain tube, this seeding method can adapt to the seed of broadcasting different shape again, but simple grain Precision Seeding rate is low, the replay rate is higher, relatively is suitable for drilling.In recent years, precise sowing at granule seeds such as vegetables, flowers, China's patent 02138075.9 has been announced a kind of magnetic-attraction precision sowing principle and device, it is made up of kind of a case, column electromagnet suction nozzle, feed mechanism, conveyer belt etc., seed is accurately drawn by electromagnet behind the magnetic dressing, the single row or multiple rows electromagnet is under feed mechanism drives, and the cave is empty and plant between the case and swing back and forth waiting to broadcast, and realizes the getting kind of magnetic head, sowing action.Because the magnetic-attraction precision sowing utilizes magnetic attraction to carry out seeding, thereby without limits to the shape of seed, size, and seeding accuracy height, but the seeding apparatus that patent 02138075.9 is announced is owing to adopt a kind of swing-bar mechanism to drive that the magnetic head is got kind back and forth, sowing, cause the magnetic head whenever to be broadcast once and plant, all want backlash, cause the seeder operating efficiency not high to getting kind of a position, motional inertia is big, and kinetic stability is poor.
Summary of the invention
In order to improve the operating efficiency of magnetic-type cave dish precise seeder, improve seeder kinetic stability, the utility model has designed a kind of magnetic drum formula cave dish precision seed metering device.
The technical scheme that its technical problem that solves the utility model adopts is: this device mainly is made up of cylinder, magnetic head, kind case, collecting ring, travel switch, travel switch block, its technical characterictic is: cylinder is non magnetic thin cylinder, the magnetic head is installed on the drum shaft, and be evenly arranged in the cylinder, magnetic head magnetic pole end face is close on the inner wall of rotary drum; Collecting ring is installed in an end of drum shaft, and external power source is inserted on the magnetic head in the swing roller, and cylinder and drum shaft are pressed the single direction rotation; Travel switch is installed on the outer wall of cylinder one side, the break-make of each travel switch control one row's magnetic head coil electric current; The travel switch block is installed in the side near travel switch, plants case and be open type, and the flange that opens wide a side abuts against on the cylinder outer wall, and the magnetic capsuled seed is close on the cylinder outer wall.
The advantage of magnetic drum formula precision seed metering device is: many row's magnetic heads can be installed on drum shaft easily, arrange the magnetic head more and rotate by single direction with cylinder, get continuously kind, sowing, high efficiency operates steadily; Magnetic head magnetic pole end face is close to inner wall of rotary drum, and the magnetic capsuled seed is close to cylinder outer wall, makes magnetic head magnetic end face remain identical gap with seed to be inhaled, and has eliminated the influence of gap variation between the two to seeding accuracy, has improved seeding accuracy.
Description of drawings:
The present invention is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is apparatus of the present invention schematic diagram.
Fig. 2 is the roller frame schematic diagram.
1. 9. kinds of casees of 3. travel switch blocks, 4. cylinder 5. travel switches, 6. drum shaft 7. magnetic heads, 8. magnetic capsuled seeds, 10. solenoids, 11. collecting rings are coiled in conveyer belt 2. caves
Embodiment
Cave dish (2) places on the conveyer belt (1), and the cave dish whenever finishes a round, and conveyer belt (1) just moves a pitch-row; Magnetic capsuled seed (8) places in the semi-open type kind case (9), the flange of planting the unlimited side of case (9) abuts against cylinder (4) outer wall, to prevent that seed (8) from dropping downwards: four row's magnetic heads (7) are installed on the drum shaft (6) separately at a certain distance, at an end of drum shaft (6) collecting ring (11) is installed, external power source is inserted on the interior magnetic head (7) of swing roller (4): the magnetic end face of magnetic head (7) is close on the inwall of cylinder (4), and cylinder (4) is non magnetic thin cylinder; Cylinder (4) one side outer wall upper edge circumference are evenly arranged four travel switches (5), and each travel switch (5) control one row's magnetic head (7) is gone up the break-make of solenoid (10) electric current; In a side one block (3) is installed near travel switch (5), when carrying magnetic capsuled seed (8), row's magnetic head (7) goes to cave dish (2) when waiting to broadcast the top in hole, cave, the travel switch (5) that connects this row's magnetic head solenoid (10) also goes to block (3) simultaneously and locates, and by block (3) depression stroke switch (5), solenoid (10) electric current is cut off, electromagnet suction disappears, and seed (8) falls in the hole, cave in the self gravitation effect; When cylinder (4) continues rotation, travel switch (5) breaks away from block (3), solenoid (10) energising, magnetic force recovers again, this moment, the magnetic head went to the unlimited place of seed-box (9) with drum shaft (6), going up solenoid (10) because of magnetic head (7) switches on, so the magnetic attraction on the magnetic head magnetic pole strength will hold magnetic capsuled seed (8), and with the rotation of cylinder (4), go to cave dish (2) once more and wait to broadcast top, hole, cave, carry out sowing for the second time, so move in circles, several rows of magnetic head is finished successively and is got kind, sowing.
