Spiral-shaped soil digging plates are arranged on the outer wall of the ditch opening wheels 5, and the soil digging plates are symmetric in the front and back. Through the shape setting of the ditch opening wheels 5, it is ensured that the soil dug out by the soil digging plates can be pushed to the left and right sides by the spiral-shaped soil digging plates, and the soil in the middle can be pushed to both sides.

[0036] Referring to Figure 1 - Figure 3, a fertilizer box 6 is fixedly connected to the top end of the bottom plate 1. A feeding mechanism 7 is arranged inside the fertilizer box 6. The feeding mechanism 7 includes a first motor 71. The bottom end of the first motor 71 is fixedly connected to the top end of the fertilizer box 6. The output shaft of the first motor 71 penetrates through the inner wall of the fertilizer box 6 and is fixedly connected with a spiral blade 72. The bottom plate 1 and the fertilizer box 6 are provided with a discharge hole at the position of the bottom end of the spiral blade 72. A slide bar 73 is fixedly connected to the inner wall of the fertilizer box 6. The outer wall of the slide bar 73 penetrates through and is slidably connected with a push plate 74. The outer wall of the push plate 74 is attached to the inner wall of the fertilizer box 6. Due to the attached positional relationship, the soil will not move to the right side of the push plate 74 through the gap between the push plate 74 and the fertilizer box 6. The right end of the push plate 74 is elastically connected to the inner wall of the fertilizer box 6 through a spring 75. One end of the spring 75 is fixedly connected to the right end of the push plate 74, and the other end of the spring 75 is fixedly connected to the inner wall of the fertilizer box 6. A box door 76 is hinged to the top end of the fertilizer box 6, and an anti-slip pad is arranged on the inner wall of the box door 76.

[0037] Refer to Figure 2 - Figure 4 , a pull rope 77 is fixedly connected to the right end of the push plate 74. An installation plate 78 is fixedly connected to the inner wall of the fertilizer box 6 at the right end of the push plate 74.

A seeder 8 is fixedly connected to the top end of the bottom plate 1 on the right side of the fertilizer box 6. The seeder 8 can place rice seeds into the soil, and this technology is an existing technology and can be realized by those skilled in the art, so it will not be described in detail in this case.

[0038] Refer to Figure 5 - Figure 7, a soil covering mechanism 9 is arranged below the right end of the seeding machine 8 on the bottom plate 1. The soil covering mechanism 9 includes a fixed cylinder 91. The top end of the fixed cylinder 91 is fixedly connected to the bottom end of the bottom plate 1. A second motor 92 is fixedly connected to the top end of the bottom plate 1. The output shaft of the second motor 92 penetrates the inner wall of the bottom plate 1 and the inner wall of the fixed cylinder 91. The output shaft of the second motor 92 is fixedly connected to a rotating rod 93. The circle corresponding to the top view of the rotating rod 93 and the fixed cylinder 91 is concentric. A rotating rod 94 is rotatably connected to the outer wall of the rotating rod 93. One end of the rotating rod 94 away from the rotating rod 93 is fixedly connected to a scraping plate 95. A moving groove 96 is formed on the outer wall of the right end of the fixed cylinder 91. The moving groove 96 is an annular groove exceeding half. The second motor 92 is arranged to rotate forward and backward reciprocally, and the rotation angle of the second motor 92 each time is the same as the angle corresponding to the moving groove 96. A gear 97 is fixedly connected to the outer wall of the rotating rod 94 inside the fixed cylinder 91. A tooth block 98 is fixedly connected to the inner wall of the fixed cylinder 91. The number of teeth of the tooth block 98 is half of that of the gear 97.

[0039] Refer to Figure 6 - Figure 8 An installation block 99 is fixedly connected to the inner wall of the fixed cylinder 91. A convex block 910 is rotatably connected to the top end of the installation block 99. The number of installation blocks 99 is set to two. The two installation blocks 99 are respectively arranged below both ends of the moving groove 96. The number of convex blocks 910 arranged on each installation block 99 is half of the number of teeth of the gear 97. The left end of the convex block 910 is elastically connected to the top end of the installation block 99 through an elastic piece 911. One end of the elastic piece 911 is fixedly connected to the left end of the convex block 910, and the other end of the elastic piece 911 is fixedly connected to the top end of the installation block 99.

[0040] Working principle: When in use, the staff pulls the pull rod 3, so that the bottom plate 1 moves driven by the rollers 2. During the movement, the ditching wheel 5 digs soil through the spiral soil excavation plate in the middle, and through the shape setting, the soil can move towards both ends driven by the blades.

[0041] At the same time of the movement, the first motor 71 and the second motor 92 are in the starting state. Therefore, the first motor 71 drives the spiral blade 72 to rotate, so that the spiral blade 72 drives the fertilizer to move downward. And during the downward movement of the fertilizer, when the fertilizer becomes less, there is extra space at the position of the left end of the push plate 74 where the fertilizer is located. Therefore, at this time, the push plate 74 moves leftward under the push of the spring 75, so that there is a force for the fertilizer to move towards the direction close to the spiral blade 72.

[0042] When feeding is required, the staff rotates the screw rod 711, so that the screw rod 711 drives the slide plate 710 to rotate during rotation, and drives the rope winding cylinder 79 to rotate through the slide plate 710, so that the pull rope 77 winds around the outer wall of the rope winding cylinder 79. Therefore, the pull rope 77 is tightened, and the push plate 74 can move to the rightmost end under the pulling of the pull rope 77, so as to ensure that the added fertilizer is all at the left end of the push plate 74.

[0043] At the same time, the rice seeds are sown under the sowing action of the seeder 8. At the same time, the rotating rod 93 rotates under the drive of the second motor 92, and drives the scraper 95 to rotate around the rotating rod 93 through the rotating rod 94. When the rotating rod 94 moves from the left end to the middle, at this time the scraper 95 is at the lower end of the rotating rod 94, so that the scraper 95 can scrape the soil at the edge to the middle.

[0044] After the rotating rod 94 moves to the middle, the gear 97 rotates half a turn under the control of the teeth of the tooth block 98. So when the rotating rod 94 moves from the middle to the right, the scraper 95 is at the upper end of the rotating rod 94, so that the scraper 95 does not contact the soil. When the scraper 95 rotates to make the teeth of the gear 97 contact the convex block 910, the teeth of the gear 97 push the convex block 910, so that the convex block 910 deflects.

[0045] After the scraper 95 moves to the rightmost end and moves to the left under the drive of the second motor 92, at this time the teeth of the gear 97 contact the convex block 910 again. Since the convex block 910 cannot deflect at this time, the gear 97 can rotate at this time, so that the rotating rod 94 rotates half a turn again, so that the scraper 95 is at the lower end of the rotating rod 94, ensuring that the soil at the edge can be pushed to the middle. After that, the above operations are repeated, so that the soil at the edge can be covered after sowing is completed.

[0046] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
