Background

Alfalfa is a generic term of alfalfa plants, commonly known as broccoli, and is a perennial flowering plant. Among the most notable are alfalfa, which is grass. Alfalfa is a variety of perennial herb plants, similar to clover, has drought resistance, high yield and excellent quality, and can improve soil, so the alfalfa is known; widely cultivated, mainly used for preparing hay, silage or used as pasture. Alfalfa is typically planted in furrows between crops in most areas of china, such as corn intercropping; can improve soil structure, and alfalfa is a perennial deep root plant. The alfalfa large root system groups are densely distributed in the soil, criss-cross, so that the soil can be dredged, the soil porosity is increased, the soil permeability is improved, and the water guide performance is enhanced. The method can be used for fertilizing the soil, improving the soil nutrient condition, and in the growing process of alfalfa, a large number of fibrous roots, root hairs and root nodules are killed and fall off continuously, and along with the extension of the planting period, the organic matters and nitrogen in the soil are gradually increased. After the alfalfa is ploughed, a large amount of organic matters are left for the soil. And the rainwater can be regulated and stored, the salinization of soil is reduced, and the yield of agricultural and livestock products is improved. The alfalfa is planted to improve the soil structure, improve the soil fertility and create a good environment for the growth of the following crops.

Then, when the traction turntable 35 rotates to draw the seeding vehicle 12 to move a certain distance, the traction is stopped, the seeding vehicle 12 stops, the control rope 27 is pulled to start the telescopic air cylinder 20 to operate through the induction controller 21, the lower detector 7 is driven through the limit long rod 51 and the synchronous linkage rod 52 to plant alfalfa seeds into soil, then the telescopic air cylinder 20 is contracted and reset to synchronously drive the lower detector 7 to reset, the traction turntable 35 rotates again to draw the seeding vehicle 12 to move forwards continuously, and the pressing roller 15 at the rear side of the seeding vehicle 12 can perform rolling compaction on an area where the alfalfa seeds are sowed.

With this is reciprocal, through the one end control traction seeding car 12 that is in the maize furrow removes, controls the operation of response controller 21 to flexible cylinder 20 start-up to the planting that carries out the alfalfa in maize furrow department when realizing that the seeding personnel does not receive the maize stalk leaf scratch, and can adjust the seeding interval of two kinds of seed boxes 41 through adjusting component 6 thereby reach the effect that is applicable to the maize furrow at different width to sow the alfalfa.

The implementation principle of the embodiment is as follows:

(1) Traction adjustment: before planting, adjusting the sowing interval which is adaptive to the width of the corn furrows through an adjusting component 6 according to the width of the actual corn furrows; the seeding vehicle 12 is then placed at one end of the corn furrow, and then the seeder is lifting the fifth wheel 1 through the corn furrow to place the fifth wheel 1 at the other end, pushing down the arc-shaped push block 292 to insert the positioning insert bar 291 into the ground through the through-hole 103 to firmly limit the fifth wheel 1 at the other end of the corn furrow.

(2) And (3) controlling movement: the traction turntable 35 is rotated to drive the traction winch 26 to rotate so as to drag the seeding vehicle 12 at the other end of the corn furrow, so that the seeding vehicle 12 can move in the corn furrow by itself, the traction is stopped after a certain distance is moved, the seeding vehicle 12 stops, the control rope 27 is pulled to start the telescopic cylinder 20 to operate through the induction controller 21, the telescopic end of the telescopic cylinder 20 moves downwards, and the two synchronous linkage rods 52 can be synchronously driven to move downwards under the action of the limiting long rod 51.

(3) And (3) operating: under the downward movement driving of the two synchronous linkage rods 52, the downward detector 7 moves downwards, and the lower ends of the downward detection V-shaped rods 74, the first conical arc plates 81 and the second conical arc plates 82 are driven to be inserted into the soil below the seeding vehicle 12 so as to facilitate the subsequent seeding of alfalfa seeds.

(4) Planting alfalfa: when the first and second conical arc plates 81 and 82 move down to the maximum stroke, the largest diameter position of the upper ends of the first and second conical arc plates will collide with the side wall of the lower penetrating opening 121, so that the first and second conical arc plates 81 and 82 can be driven to rotate far away from the lower V-shaped rod 74, namely, the first and second conical arc plates are expanded outwards to spread out soil, alfalfa seeds originally in the conical barrel formed by the first and second conical arc plates can be scattered outwards and planted into the spread soil, after sowing is completed, the sowing vehicle 12 is pulled to move forwards continuously, and the pressing roller 15 at the rear side of the sowing vehicle 12 can perform rolling compaction on the area where the alfalfa seeds are sowed.

The embodiments of the present application are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in this way, therefore: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
