Abstract

The utility model discloses a cured tobacco floating seeder, comprising a locating plate, sieve plates, a sliding key pulley, a residual seed sliding door and an outlet. The locating plate is arranged at the top of a frame(2) and the fixed sieve plate(4)is fixed inside the frame(2); the sliding sieve plate(3) is disposed on the fixed sieve plate(4) and can slide relatively with respect to the fixed sieve plate(4) ; the sliding key pulley(5) is arranged on the sliding sieve plate(3)and a pullback spring(6)is arranged in the groove of the sliding sieve plate(3) and the fixed sieve plate(4) below the sliding key pulley(5); the residual seed outlet(8)is arranged at one end of the seeder and is controlled by the residual seed sliding door(7) to open or close. The cured tobacco floating seeder is simple in structure, convenient to operate, accurate in seeding quantity, with each hole having no more than 2 seeds, thus saving seeds; meanwhile, the cured tobacco floating seeder is added with an residual seed outlet, thus reducing the working time of cleaning up the residual seeds inside the seeder.

Description

The floating seedling cultivation of fire-cured tobacco seeder

Technical field

The utility model relates to a kind of floating seedling cultivation of fire-cured tobacco seeder that is exclusively used in the floating seedling cultivation of fire-cured tobacco dish.

Background technology

Flue-cured tobacco seedling-cultivating is a most important link in the tobacco planting process, the good and bad quality and the output that directly influences flue-cured tobacco of growing seedlings.In promoting the floating seedling cultivation of fire-cured tobacco technical process, adopt manual dibbling at present, work efficiency is low, and easily germ is brought in the seedling-cultivating tray more.Existing manual seeder, its complex structure, cost height, and every hole sowing grain number is up to the 3-8 grain.

Summary of the invention

The purpose of this utility model aim to provide a kind of work efficiency height, simple in structure, easy to operate, sow floating seedling cultivation of fire-cured tobacco seeder accurately.

The utility model is by framework, location-plate, fixed screen deck, slip sieve plate, slide group key, return spring, residue seed slide and export mixes.Location-plate is positioned at the framework top, and fixed screen deck is fixed in the framework, and the slip sieve plate places on the fixed screen deck and can be with respect to the fixed screen deck pitch-row of sliding, and the hole on the slip sieve plate is less than the hole on the fixed screen deck; Have one slide to dial key on the slip sieve plate, a spring once in the groove of dialling key lower slider sieve plate and fixed screen deck that slides; Leave the residue seed export at seeder one end, it opens and closes by the control of residue seed slide.

Floating seedling cultivation of fire-cured tobacco seeder of the present utility model is simple in structure, easy to operate, and seeding quantity is accurate, and every hole is no more than 2, has saved the seed consumption.And, reduced the man-hour of the unnecessary seed of cleaning seeder owing to increased residue seed export part.

Specific embodiments

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, seeder of the present utility model is the 1/2 big of floating seedling cultivation of fire-cured tobacco dish, when being positioned on the seedling-cultivating tray, location-plate (1) location by seeder framework (2) top, slip sieve plate (3) places fixed screen deck (4) to go up and can be with respect to fixed screen deck (4) pitch-row of sliding, and the hole on the slip sieve plate (3) is less than the hole on the fixed screen deck (4).

As Fig. 5, Fig. 6, shown in Figure 7, there is a slip to dial key (5) on the slip sieve plate (3), slide to dial in the groove of key (5) lower slider sieve plate (3) and fixed screen deck (4) position spring (6) once, when seeder was not sowed, slip sieve plate (3) and fixed screen deck (4) were in state as shown in Figure 6; When seeder was worked, stirring slides dialled key (5), and return spring (6) is compressed, and slip sieve plate (3) and fixed screen deck (4) are in state as shown in Figure 7.

As Fig. 8, shown in Figure 9, leave residue seed export (8) at seeder one end, it opens and closes by stirring residue seed slide (7) control.

The utility model residue seed export (8) course of work is as follows: seeder is placed on the floating seedling cultivation of fire-cured tobacco dish (9), be located on seedling-cultivating tray (9) 1/2 positions by location-plate (1).After seed is poured seeder into, stirring slides dials key (5), compression retracteding position spring (6) drives slip sieve plate (3) and slides with respect to fixed screen deck (4) in framework (2), aliging with the hole of fixed screen deck (4) in slide the as shown in Figure 7 hole of sieve plate (3), places the seed on the slip sieve plate (3) to fall into the corresponding hole of floating seedling cultivation of fire-cured tobacco dish (9) through the hole of fixed screen deck (4).Loosening slides dials key (5), and under the effect of return spring (6), slip sieve plate (3) is got back to position as shown in Figure 6, finishes the process of once sowing.After whole sowing work is finished, stir residue seed slide (7), remaining seed is poured out by residue seed export (8).

The utlity model has simple in structure, with low cost, easy to operate characteristics, broadcast Kind of amount precisely, every hole is no more than 2, saving of work and time is economized kind, and speed of drilling is fast, effect The rate height.
