[0022] The present invention will be further described below with reference to the accompanying drawings. Figure 1 :

[0023] A furrowing and soil-covering device of a seeder comprises a tube body 1, wherein a seed-dropping funnel 2 is connected to the upper end of the tube body 1, a seed-dropping passage is formed through the inner hole of the tube body 1, and an integrally formed functional part is connected to the lower end of the tube body 1, wherein the functional part comprises, from front to back, a furrowing section 3, a seed-dropping section 4 and a soil-covering section 5, wherein the cross section of the furrowing section 3 is V-shaped, the seed-dropping section 4 is arranged corresponding to the inner hole of the tube body 1, and the soil-covering section 5 comprises a pair of soil-covering plates distributed left and right, and the soil-covering plates are arranged to be inclined outward from top to bottom.

[0024] When in use, multiple trenching and covering devices are respectively installed below the seed dropping structure of the seeder (such as a seed dropping pipe or a seed dropping hole). When the seeder moves forward, the trenching section 3 acts on the soil to form ridges for sowing, and the seeds in the seeder hopper fall into the sowing groove along the seed dropping structure, the seed dropping funnel 2 and the inner hole of the tube body 1. The covering plate then acts on the ridged soil to cover the seeds to complete the sowing.

[0025] In this embodiment, the tube body 1 is a square tube, and the seed dropping funnel 2 is selected according to the seed dropping structure of the seeder, such as a square funnel or a rectangular funnel.

Preferably, the bottom notch 6 is an L-shaped notch, wherein the vertical notch separates the seed dropping section 4 and the soil covering section 5, and the horizontal notch corresponds to the seed dropping area. By providing the notch, the soil covering plate can be bent more easily, and a sufficient time gap can be left between seed dropping and soil covering to better complete the sowing.

[0027] There are many options for the shape of the trenching section 3, for example, the front end of the trenching section 3 is tilted backward from top to bottom, the front end of the trenching section 3 is tilted forward from top to bottom, or the front end of the trenching section 3 is vertically arranged. Preferably, the front end of the trenching section 3 is tilted forward from top to bottom, and the trenching section 3 of this structure has the minimum trenching resistance.

[0028] In order to facilitate the production of functional parts, the functional parts are formed of metal sheets, the middle parts are bent relative to each other to form the trenching section 3, and the ends are bent outward to form the soil covering section 5. Preferably, the bottoms of the trenching section 3, the seed dropping section 4 and the soil covering section 5 are located in the same plane.

[0029] The lower end of the seed dropping funnel 2 is detachably plugged and fixed to the upper end of the tube body 1 to facilitate replacement of a suitable seed dropping funnel 2 . The upper end of the seed dropping section 4 is fixedly connected to the lower end of the tube body 1 .

Further, the locking member 8 includes a threaded hole, and a locking bolt is threadedly connected in the threaded hole, which penetrates the side wall of the up-and-down adjustment mounting seat 7 and abuts against the outer wall of the pipe body 1 to lock. When adjusting, first loosen the locking bolt, slide the up-and-down adjustment mounting seat 7 up and down to a suitable position, and then tighten the locking bolt to lock.

[0033] Further, a left-right adjustment mounting seat 9 is fixed to the rear side of the up-down adjustment mounting seat 7, and the left-right adjustment mounting seat 9 is slidably arranged on the crossbeam of the seed drill. Further, a plurality of mounting holes are arranged on the left-right adjustment mounting seat 9, and the left-right adjustment mounting seat 9 is fixed to the crossbeam of the seed drill through fasteners in the mounting holes. When adjusting, the left-right adjustment mounting seat 9 is first placed at a suitable position on the crossbeam of the seed drill, and then fastened to the crossbeam using fasteners such as bolts.

[0034] In this embodiment, the up-and-down adjustment mounting seat 7 is a square sleeve adapted to the tube body 1, and the left-and-right adjustment mounting seat 9 is a U-shaped seat with an outward opening.
