Abstract
The utility model relates to a semi-closed outer slot wheel which belongs to a component assembly of an agricultural seeding machine. The semi-closed outside slot wheel is composed of a wheel shaft, a seeding quantity adjusting lever, a semi-closed outer slot wheel, a seed discharging box, a press cover, a seed limiting wall panel and an elastic seed scraping tongue. The utility model has the characteristics of novel and simple structural design and strong versatility, and not only can conduct socket seeding and drill seeding, but also control the size of the seeding quantity.
Description
The utility model belongs to agricultural seeder machinery manufacturing field of equipment.
Prior art in the utility model prior art field is: spoon is ladled out formula, the wheeled seeder of nest eye, and its weak point is: the one, and complex structure, processing charges height; The 2nd, versatility is poor; The 3rd, seeding quantity is wayward; The 4th, can only nest broadcast and can not drilling.
Purpose of design of the present utility model is: avoid weak point of the prior art, but design a kind of simple in structure, be easy to processing, highly versatile, both nest broadcast, drilling, the semi-closed fluted roller seeding unit of controlled seeding quantity again.
Design of the present utility model is: main feature of the present utility model is to adopt major diameter, little flute profile, semienclosed outer groove-wheel.Because flute profile and seed touch opportunity what the filling performance of seed wheel depends on, it is the arc length of flute profile part, regularly be directly proportional at adjacent two groove angles one with the radius of seed wheel, and the little flute profile by the processing of seed physical dimension can realize filling in right amount off and on corresponding arc length, reaches the requirement of bunch planting; As desire the rotating speed that drilling then can be used the more outer groove-wheel of groove number instead and improve seed wheel, can realize drilling, thereby solve the technical barrier that existing bar, bunch planting seeding unit can not be general.Organization plan: the semi-closed fluted roller 3 of semi-closed fluted roller seeding unit is enclosed within on the wheel shaft 1, axially be shaped on 1～30 seed distributing groove 9 on the semi-closed fluted roller 3, seeds discharging box 4 is enclosed within on the semi-closed fluted roller 3, gland 6 is enclosed within on the semi-closed fluted roller 3 and with a side of seeds discharging box 4 with limit kind of a wallboard 7 and is connected, elasticity is scraped kind of tongue 8 and is positioned at the bottom of seeds discharging box 4 and touches mutually with the external diameter of semi-closed fluted roller 3, seeding-rate adjusting lever 2 is interference fits by the fork slot of steel ball and semi-closed fluted roller, control moving axially of semi-closed fluted roller 3, thereby the control seeding quantity what reach.
The utility model compared with prior art, the one, have novel structure, simple, be easy to process, general, practical characteristics; The 2nd, but both nest broadcast, drilling, what of controlled seeding quantity again.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the main TV structure schematic diagram of semi-closed fluted roller.
Fig. 3 is the left TV structure schematic diagram of semi-closed fluted roller.
Embodiment:
1～3 pair of the utility model is done with narration in conjunction with the accompanying drawings.
At first make wheel shaft 1, seeding-rate adjusting lever 2, semi-closed fluted roller 3, seeds discharging box 4, gland 6, limit kind of wallboard 7 and elasticity and scrape kind of tongue 8 with reference to accompanying drawing 1～3; Semi-closed fluted roller 3 is enclosed within on the wheel shaft 1, seeds discharging box 4 is enclosed within on the semi-closed fluted roller 3, gland 6 and limit kind of wallboard 7 adopt rivets 5 to be fixed on the sidepiece of seeds discharging box, and elasticity is scraped its tongue of bottom that kind of tongue 8 is fixed on seeds discharging box 4 and touched mutually with the external diameter of semi-closed fluted roller.When seed wheel rotates, fall into the seed of the seed distributing groove 9 of semi-closed fluted roller, promptly turn to the seeds discharging box exit and fall into the soil ditch with sheave; Limit kind of a wallboard 7 is limited in seed not make in the seeds discharging box and slips out or damage; Elasticity is scraped 8 in kind of tongue surplus seed more than on the outer groove-wheel is scraped off, guarantee quantitatively (grain number) filling, and the mat elastic reaction is with the rotary resistance situation of change, on the sheave outer rim, move about and unlikely damage seed, move axially what of semi-closed fluted roller 3 controlled seeding quantitys by seeding-rate adjusting lever 2.
Claims (2)
1, a kind of semi-closed fluted roller seeding unit, it is characterized in that: semi-closed fluted roller 3 is enclosed within on the wheel shaft 1, seeds discharging box 4 is enclosed within on the semi-closed fluted roller 3, gland 6 is enclosed within on the semi-closed fluted roller 3 and with a side of seeds discharging box 4 with limit kind of a wallboard 7 and is connected, elasticity is scraped kind of tongue 8 and is positioned at the bottom of seeds discharging box 4 and touches mutually with the external diameter of semi-closed fluted roller 3, seeding-rate adjusting lever 2 is interference fits by the fork slot of steel ball and semi-closed fluted roller, control moving axially of semi-closed fluted roller 3, the control seeding quantity what reach.
2, semi-closed fluted roller seeding unit according to claim 1 is characterized in that: axially be shaped on 1～30 seed distributing groove 9 on the semi-closed fluted roller 3.
