Problems solved by technology

[0002] With the continuous development of protected horticulture, industrialized seedling cultivation has been promoted on a large scale. Due to the small size and irregular shape of flowers and vegetable seeds, the speed of artificial sowing is very low, the cost of sowing is high, and the distribution of sowing seeds is uneven. Facilitate the growth and cultivation of seedlings
At present, the seed metering device of the plug seedling seeding machine used is fixed on the seeding machine, so that one kind of seeding machine can only be used for a few kinds of seeds. It is generally used for large-scale industrial seedling cultivation, and most of them are imported from abroad. Expensive, which limits its applicability

Embodiment 1

[0026] A handheld seeder such as Figure 1~3 Shown includes casing 1, seed box 4, driving shaft, driven shaft, belt 7, seeding belt 9, rocker 10, baffle plate 5 and partition 6; Set on the front side of the lower end of the inner shell 1; the driving shaft and the driven shaft are arranged on the inner front side of the shell 1 at intervals up and down, the driving shaft extends out of the shell 1, and is connected with the rocker 10, and the driven shaft is located inside the seed box 4; The shaft has the same structure as the driven shaft, and is composed of a support shaft 2 and a sprocket 3 sleeved on the support shaft 2, and the support shaft 2 and the sprocket 3 are connected by a key. The support shaft 2 is fixed on the shell through bearings, and the rocking bar 10 is connected with the support shaft 2 on the drive shaft, and the belt 7 is looped between the two sprockets 3 . The supporting shaft 2 and the sprocket 3 are made of metal materials. The length of the sup...

Embodiment 2

[0031] The difference with Embodiment 1 is that in the present embodiment, the belt 7 is provided with 910 seeding belts arranged in parallel vertically, such as Figure 5 As shown, in the present embodiment, the size of the plug tray sown is 10 × 20, and the distance between the centers of the seeding belts 9 is 2.6 centimeters. During actual use, the number of single sowings can be adjusted according to the size of the sown tray, the number of the seeding belts 9 and the spacing between the seeding belts 9, and the size of the seeding belts 9 can be adjusted according to the size of the sown seeds.

Abstract

The invention relates to a handheld seeder, which comprises a shell, a seed box, a driving shaft, a driven shaft, a belt, a seed sowing belt, a rocker, a baffle and division plates. The lower end of the shell is provided with a seed sowing mouth, and the seed box is arranged in the shell at the front side of the lower end; the driving shaft and the driven shaft at intervals are arranged at the front side in the shell at internal, the driving shaft extends out of the shell and is connected with the rocker, and the driven shaft is located in the seed box; the belt surrounds between the driving shaft and the driven shaft; the seed sowing belt is located at the outer side of the belt, and provided with a seed groove; the baffle is located at the rear side in the shell and behind the seed sowing belt; and the division plates are arranged at the left and right sides of the seed sowing belt and the baffle, and has the lower end extending to the seed sowing mouth. The invention has the advantages of simple structure and convenience for usage; because the seed sowing belt and the baffle plate can be disassembled, and the seeder is applicable for sowings seeds with different sizes in different types of plug trays by adjusting the the number and position of the seed sowing belt and partition plates. The invention expands the scope of application of the handheld seeder and reduces the sowing cost.

Description

technical field [0001] The invention relates to a seeder, in particular to a hand-held seeder, and belongs to the technical field of plug seedling cultivation engineering. Background technique [0002] With the continuous development of protected horticulture, industrialized seedling cultivation has been promoted on a large scale. Due to the small size and irregular shape of flowers and vegetable seeds, the speed of artificial sowing is very low, the cost of sowing is high, and the distribution of sowing seeds is uneven. Conducive to the growth and cultivation of seedlings. At present, the seed metering device of the plug seedling seeding machine used is fixed on the seeding machine, so that one kind of seeding machine can only be used for a few kinds of seeds. It is generally used for large-scale industrial seedling cultivation, and most of them are imported from abroad. High, which limits its scope of application. Therefore, it is urgent to design a seeder with simple st...
