Embodiment

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4.

Density vegetable seed sower, by: seeding wheel 1, sowing wheel shaft 2, change pulley 1, driving belt 4, change pulley 25, handle 6, Seeding box 7, frame 8, sowing roller 9, seal 10 are formed.

Seeding wheel 1 is installed on the sowing wheel shaft 2, sowing wheel shaft 2 ends are equipped with change pulley 1, sowing wheel shaft 2 is installed on the frame 8, sowing roller 9 is installed on the frame 8, Seeding box 7 is positioned at the top of sowing roller 9 and is installed on the frame 8, is provided with seal 10 between Seeding box 7 and the sowing roller 9, and the end of sowing roller 9 is equipped with change pulley 25, be connected by driving belt 4 between change pulley 1 and the change pulley 25, handle 6 is installed on the frame 8.

Change pulley 1, change pulley 25 is the combined type belt pulley of the tapered structure that formed by the different-diameter stack combinations, change pulley 1 is all identical with change pulley 25 structures and size, change pulley 1 is position installation in opposite directions with change pulley 25 in the end of sowing wheel shaft 2 and sowing roller 9, its belt grooves is aligned with each other, the girth unanimity that is constituted between the belt grooves of its big or small pairing aligned with each other, driving belt 4 is set in the belt grooves of change pulley 1 and change pulley 25, driving belt 4 of a suit between change pulley 1 and change pulley 25.

Sowing wheel shaft 2 and frame 8 are provided with the adjusting device that can regulate spacing between seeding wheel axle 2 and the sowing roller 9.Seal 10 is the rubber-like flexible material of spongelike structure, and seal 10 is installed in the Seeding box 7, and contacts applying with sowing roller 9 surfaces, in the movement clearance of seal 10 fillings between Seeding box 7 and sowing roller 9.

Driving belt 4 is installed on change pulley 1, on the change pulley 25, and be installed in both intermediate belt groove positions, driving belt 4 one of installation are just passable, seed is positioned in the Seeding box 7, lifting handle 6 promotion sowers then travels forward, seeding wheel 1 rolls in the ground when sower travels forward, the rolling of seeding wheel 1 drives sowing wheel shaft 2 and rotates, sowing wheel shaft 2 rotates and drives change pulley one 3 rotations, change pulley 1 rotates by driving belt 4 and drives change pulley 25 rotations, thereby change pulley 25 rotates and drives 9 rotations of sowing roller, sowing roller 9 just rotates the many grooves of the seed in the Seeding box 7 by sowing roller 9 surfaces is brought out seed like this, fall down from the lower position of sowing roller 9 then and be seeded in the ground, press certain line-spacing and spacing in the rows on sowing roller 9 surfaces, the well-regulated groove that is provided with some, each groove size of generally sowing roller 9 surfaces should be suitable with seed size, and each groove only can be taken a seed out of in 9 each commentaries on classics of sowing roller like this.

When the sowing that will enlarge plant apart from the time, in the time of promptly will enlarging the sowing line-spacing between plant, as long as driving belt 4 is outwards regulated, at this moment the belt grooves diameter of change pulley 1 is less than the belt grooves diameter of change pulley 25, transmission is the effect of playing deceleration, so just enlarge seed spacing, thereby changed the thickness of sowing of plant.

When the sowing that will dwindle plant apart from the time, in the time of promptly will dwindling the sowing line-spacing between plant, as long as driving belt 4 is inwardly regulated, at this moment the belt grooves diameter of change pulley 1 is greater than the belt grooves diameter of change pulley 25, transmission is the effect of playing speedup, so just dwindle seed spacing, thereby changed the thickness of sowing of plant.

When seed is sowed roller 9 when Seeding box 7 is taken out of, owing to exist movement clearance between sowing roller 9 and the Seeding box 7, so between this gap, be provided with seal 10, sealing part 10 can adopt sponge material, the gap that thickness is a bit larger tham between sowing roller 9 and the Seeding box 7 is just passable, and seal 10 sponge materials are filled the gap and are closed.Like this when sowing roller 9 rotates, the unnecessary seeds in sowing roller 9 surfaces will be by the sponge retaining in Seeding box 7, and the seed that prevents to be arranged in sowing roller 9 surfaces is sowed roller 9 and brought the gap into and cause breakage when sowing roller 9 rotates.
