Embodiment 1

[0029] This embodiment is mainly applicable to single-seed sowing in seedling holes. Single-seed sowing is more conducive to tillering of seedlings, indirectly reduces the amount of seeds used, and reduces the cost of sowing. The rice seedling raising quantitative seeding device includes a conveyor belt 5 driven by a driving machine 4 and a sowing assembly arranged above the conveyor belt. The conveyor belt is connected by the rollers on both sides. There is a sprocket on each side of the two rollers. The sprockets on the same side are connected by the inner chain of the double chain, and the outer side of one of the sprockets is also coaxial. A driven sprocket is provided, and the driving motor is connected with the driven sprocket through a chain. The outer chains on both sides are fixed with a limit baffle 6 positioned above the conveyor belt. The whole set of devices is assembled on the skeleton structure (as long as it is a skeleton structure that can play a supporting r...

Embodiment 2

[0039] This embodiment is mainly applicable to the single seed sowing of other types of seedling trays different from the honeycomb structure of Example 1, and the single-row groove seed board 7 can be replaced by the misplaced groove seed board 14 .

Embodiment 3

[0041] This embodiment is mainly suitable for seeds with a low germination rate. Although single seed sowing is more conducive to tillering of seedlings, if germination cannot be caused due to its own factors, it will seriously affect the efficiency of seedling cultivation, indirectly increase the amount of seeds used, and improve the efficiency of sowing. cost. For this reason, the single-row groove seed board 7 can be replaced by a double-row groove seed board 13 .

Abstract

The invention discloses a quantitative seeding device for rice seedling culture. The quantitative seeding device comprises a conveyer belt and a seeding component, wherein the conveyer belt is driven by a driving machine; the seeding component is arranged above the conveyer belt. The technical key point is that the seeding component comprises a driving chain, a seed plate and a vibration component, wherein the seed plate can be clockwise or anticlockwise spaced on the driving chain in an overturning manner; the vibration component is arranged above the seed plate; the vibration component comprises a vibration frame and a vibration motor which is used for driving the vibration frame. The quantitative seeding device can be used for fundamentally solving the problem that the conventional seeding devices are low in seeding efficiency and bad in seeding effect, and has the advantages of being simple and compact in structure, convenient to operate, high in seeding efficiency, good in seeding effect and small in floor space.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a quantitative seeding device for rice seedling raising, which is mainly suitable for single-grain or multi-grain directional and precise seeding when rice seedlings are raised before transplanting. Background technique [0002] The planting of rice mainly includes three steps of soil preparation, seedling raising and transplanting. When raising seedlings, the existing seedling raising and sowing mainly depends on the seeder, and the sowing amount cannot be guaranteed. However, manual quantitative sowing is too labor-intensive, and it is difficult to ensure the sowing efficiency and sowing effect. [0003] Such as the existing sowing device, such as a "rice seedling seeding single-grain separation mechanism" disclosed in the invention patent with the authorized announcement number CN103636326B, the front and rear sides of the frame assembly are equipped with front and rear d...
