Abstract

The utility model provides a paddy seedling disk precision drill. The technical features are that the seeding rate and the pitch of the drill are matched with the bowl hole of a paddy seedling disk, the upper plate of the drill is provided with a seed storing box, the lower plate is provided with a rotating cam, and a compression spring is provided between the side surfaces of the two plates. And therefore, the seeding achieves the semi-automatic quantitative hole seeding in a certain position, and the purposes of improving the qualities of the seedlings and the work efficiency and reducing the labor intensity are achieved. This technology is suitable for the seedling growing with the paddy seedling bowl disks and can also be used for the seedling growing with dry beds.

Description

Paddy seedling disk precision drill

The utility model belongs to the agricultural seeder facility.

On the rice seedling throwing dish, grow seedlings, existing method is to adopt the manual native seeding method that mixes, be exactly with seed with after soil mixes, install in the alms bowl hole of seedling-cultivating tray, the shortcoming of this method is that seeding quantity has and has less more in each alms bowl hole on the seedling-cultivating tray, the rare close inequality of broadcasting between Kong Yukong, the upper and lower skewness of kind grain in the alms bowl hole, thus the quality of rice shoot influenced, the waste seed, also has manual operations, the shortcoming that efficient is low, labour intensity is big.

The utility model provides a kind of Precision Seeding machine that the rice seedling throwing dish is grown seedlings, and it can make seed broadcast more uniformly in the alms bowl hole, improves the quality and work efficiency, reduces labor intensity.

The technical solution of the utility model is: a kind of rice seedling throwing dish precise hole sowing machine, have base plate and upper plate, two plate faces overlap contact, the compression spring is arranged between the end face of two plates, it is characterized in that: several feed outlets are arranged on the base plate, and the mutual arrangement mode in this hole is identical with the alms bowl hole of rice transplanting dish with pitch-row, upper plate has individual kind of the hole of filling out of working hard, the mutual spacing in this hole is identical with the spacing of feed outlet, and upper plate one end has seed storage box, and base plate one end has rotating cam.

The base plate of present technique overlaps with upper plate and contacts, and the position, hole on two plates interlaces, during use, earlier seed is filled up in kind of the hole of filling out of upper plate, unnecessary seed is recovered to seed storage box, is placed on then on the alms bowl dish, the feed outlet of base plate aligns with the hole, cave of alms bowl dish, rotating cam, and cam can promote the upper plate displacement, after the upper plate displacement, alignd with the feed outlet of base plate in kind of the hole of filling out of upper plate, become through hole, so fill out the seed in kind of the hole, broadcast by feed outlet in the hole, cave of alms bowl dish, realize bunch planting.Decontrol cam, the compression spring promotes the upper plate return.

Because the feed outlet of filling out kind of hole and base plate of upper plate, distance between the distribution in its hole, the capacity in hole, hole, all by the rice seedling throwing dish seedling growing process requirement design that matches, so sowing can realize hole, bunch planting, quantitatively, located, overcome the upper and lower skewness of kind grain that mixed soil is slightly broadcast generation, rare close irregular phenomenon, compared with the prior art, can improve seedling quality and operating efficiency.

Below in conjunction with accompanying drawing, an embodiment of the present utility model is described.

Fig. 1 is the front view of the utility model rice seedling throwing dish precise hole sowing machine.

Fig. 2 is the A-A view of the utility model Fig. 1.

Fig. 3 is the B-B view of the utility model Fig. 1.

Base plate among the figure (3) is evenly distributed with hard work feed outlet (8), arrangement mode between this hole and pitch-row are from all identical with the alms bowl hole of rice seedling throwing dish, press strip (5) is fixed on the long limit of base plate by bolt (9), base plate (3) middle part also has caging bolt (10), the base plate minor face has rotating cam (6), pasting base plate (3) upper plate (4) is being arranged, arrange with feed outlet (8) dislocation of base plate in kind of the hole (7) of filling out of upper plate (4), pitch-row is identical, capacity is pressed the specification requirement design of rice transplanting dish, press strip on the base plate (5) and caging bolt (10) are used for limiting the position that upper plate (4) makes progress, one end of upper plate (4) has seed storage box (1), between two sides of upper plate (4) and base plate (3) compression spring (2) is arranged.

Claims

1, a kind of rice seedling throwing dish precise hole sowing machine, have base plate and upper plate, two plate faces overlap contact, and the compression spring is arranged between the end face of two plates, it is characterized in that: several feed outlets are arranged on the base plate, and the mutual arrangement mode in this hole is identical with hole, rice transplanting dish cave with pitch-row.Upper plate has several to fill out kind of a hole, and this hole mutual spacing is identical with the spacing of feed outlet, and upper plate one end has seed storage box, and base plate one end has rotating cam.
