Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0071] like Figures 1-4 As shown, this embodiment provides a self-propelled grain planter for simultaneous fertilization, including a body 2, front wheels 1 and rear wheels 4 disposed at the front and rear ends of the body 2, and a drive system for driving the wheels (front wheels or rear wheels) forward. A cab 3 is provided on the body 2.

[0072] A rear frame 5 is provided on the vehicle body 2 near the rear wheel 4. The rear frame 5 is connected to the seed box 8 via a connecting frame 6. The seed box 8 is hinged to the cover 7 via a hinge connector. The seed box 8 is provided with a partition plate inside, which divides it into two sets of storage chambers, namely a crop storage chamber and a fertilizer storage chamber. The crop storage chamber is used to store crop seeds, and the fertilizer storage chamber is used to store fertilizer.

[0073] The discharge end of the crop storage chamber is connected to the seed guide box 121 of the furrow seeder 12. The seed guide box 121 is made of stainless steel tube, and a sealing plate 123 is embedded in the outer wall of the outlet end of the seed guide box 122. The sealing plate 123 is set in an inclined arc shape to wrap the guide plate 124 which is integrally set with the seed guide box 121. The sealing plate 123 is made of rubber material.

[0074] In this embodiment, the sealing plate 123 prevents the seeds from leaking out during the falling process.

[0075] Furthermore, a branch pipe 128 is provided near the outlet end of the guide plate 124 and is integrally formed therewith. The end of the branch pipe 128 away from the guide plate 124 is triangular in shape. A zinc plate 125 is provided on the outer wall of the guide plate 124, and the zinc plate 125 is welded to the guide plate 124 and the outer wall of the branch pipe 128.

[0076] Furthermore, the zinc plate 125 and the outer wall of the branch pipe 128 have an inclination angle α, which is 20°-75°.

[0077] When the tilt angle a is 25° and the thickness of the zinc plate 125 is 10mm, and both the zinc plate and the branch pipe 128 are made of high-strength alloy steel, the furrow seeder 12 can prevent seeds from leaking out during the falling process through the sealing plate 123, while also meeting the requirement that the furrow seeder can easily penetrate the soil, thus improving work efficiency.

[0078] In this embodiment, those skilled in the art should understand that the function of the branch pipe 128 is to ensure that a uniformly shaped trench can be dug in the soil during the sowing process. Therefore, in practical applications, if the required trench width is set to 8cm and the depth to 5cm, the required force F is:

[0079] F = C * B * H

[0080] Where C is the soil resistance coefficient (obtained experimentally as C = 1.5 N / cm²), B is the trench width, and H is the trench depth;

[0081] Therefore, the required F is 60N.

[0082] Furthermore, the rear end face of the branch pipe 128 is provided with a mounting bracket 126 by welding or other fixed connection methods, and a connecting rod 127 is fixedly installed on the mounting bracket 126 by fastening screws, and a fertilizer pipe assembly 129 integrated with the connecting rod 127 is provided on the connecting rod 127.

[0083] Furthermore, the fertilizer pipeline assembly 129 includes a fertilizer guide pipe 1293, and the fertilizer guide pipe 1293 is connected to the outlet end of the fertilizer storage chamber.

[0084] Furthermore, the fertilizer pipeline assembly 129 also includes a storage end 1295, and the fertilizer guide pipe 1293 extends into the storage end 1295 so as to transport fertilizer into the storage end 1295 through the fertilizer guide pipe; and a baffle plate 1294 for guiding the material is provided on the side end face of the storage end 1295.

[0085] Furthermore, an ear plate 1291 is integrally formed on the outer wall of the storage end 1295, and two sets of ear plates 1291 are arranged opposite each other. A soil-breaking blade 1292 is installed on the two sets of opposite ear plates 1291, and the width of the soil-breaking blade 1292 is 28mm; and the soil-breaking blade 1292 extends into the soil at an angle of 23.5°.

[0086] In this embodiment, since the soil-breaking blade 1292 extends into the soil at an angle of 23.5° and the width of the soil-breaking blade 1292 is 28mm, it is easier to reduce the soil cutting resistance and ensure that the soil is loosened evenly.

[0087] In this embodiment, by adding a soil-breaking blade to the end of the fertilizer-feeding pipe assembly 129, the soil at the fertilizer-feeding location is ensured to be loosened evenly, thereby reducing the force required by the furrow opener. The furrow opener only needs to ensure the depth of the seed furrow. Therefore, this invention only requires the addition of a zinc plate. When the tilt angle α of the zinc plate is 25° and the thickness of the zinc plate 125 is 10mm, and both the zinc plate and the branch pipe 128 are made of high-strength alloy steel, the furrow opener 12 can prevent seeds from leaking out during the falling process through the sealing plate 123, while also meeting the requirement that the furrow opener can easily penetrate the soil, thus improving work efficiency.

[0088] Furthermore, the front end of the seed box 8 is fixedly mounted with a mounting frame 9 by fastening screws, and a rotary tiller assembly 10 is provided on the mounting frame 9. The rotary tiller assembly 10 includes a rotary tiller shaft 101, and the rotary tiller shaft 101 is mounted on a drive system system on the mounting frame 9. The drive system is preferably a rotary motor.

[0089] At least one set of rotary tillage discs is fixedly installed on the rotary tillage shaft 101 by fastening screws, and rotary tillage blades 103 are provided on the rotary tillage discs. The rotary tillage blades 103 also include rotary tillage blade tips 102. When the included angle B of the rotary tillage blade tips 102 is 115°, the rotary tillage blade tips 102 will extend into the soil at a certain angle. When the rotary tillage blades are lifted, the hook-shaped rotary tillage blade tips will turn over the soil, thereby improving the soil loosening effect.

[0090] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not restrictive. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solution of this utility model do not depart from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
