DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 , the utility model provides a technical solution:

[0023] Embodiment 1:

[0024] A cotton rotary tillage ridging seeder comprises a ridging trailer 1, wherein a rotary tillage cabin 2 and a ridging cabin 3 are provided in the ridging trailer 1, a rotary tillage shaft 4 is fixedly installed in the rotary tillage cabin 2, a rotary tillage blade wheel 5 is fixedly installed on the rotary tillage shaft 4, a plurality of ridging openings 6 evenly spaced are provided at the rear of the ridging cabin 3, and corresponding ridge distance adjustment plates 7 are movably installed at the ridging openings 6, and the ridge distance adjustment plates 7 comprise left-right symmetrically arranged ridging baffles 8, and the left-right symmetrically arranged ridging baffles 8 are synchronously translated and slid toward or away from each other on both sides of the ridging openings 6 to adjust the ridge distance;

[0025] A seeding mechanism is also provided on the ridging cabin 3 between the rotary tillage cabin 2 and the ridge spacing adjustment plate 7. The seeding mechanism corresponds one-to-one to the ridging mouth 6. The ridging cabin 3 is provided with seeding holes 9 in a one-to-one corresponding manner. The seeding holes 9 are arranged in front of the center line of the ridging mouth 6. The seeds are planted through the seeding holes 9 into the soil before ridging by the seeding mechanism.

[0026] In this embodiment, the ridging trailer 1 is installed on the trailer through the towing connecting rod 27, and the ridging and sowing operation is performed as the trailer moves. Before ridging, the soil needs to be rotary tilled and loosened, and it is more convenient to perform the ridging operation after loosening the soil. The rotary tillage operation is achieved through the rotary tillage shaft 4 and the rotary tillage wheel 5 installed thereon. The power of the rotary tillage shaft 4 comes from the transmission shaft of the trailer or the rotary tillage drive mechanism installed by itself, which can be a motor or a diesel engine, etc. Since it is widely used in the prior art, it will not be repeated here. The soil after rotary tillage is shaped through the ridging mouth 6 Unlike the prior art, the present application is provided with a ridge spacing adjustment plate 7 at the end of the ridge forming mouth 6, which is realized by two left-right symmetrical ridge forming baffles 8. The ridge forming baffles 8 adjust the ridge spacing by translational sliding. At the same time, a seeding mechanism is provided between the rotary tillage cabin 2 and the ridge spacing adjustment plate 7. The seeding mechanism is used to plant seeds in the soil before ridge forming. This planting method does not require an additional external seeding mechanism, and the seeding mechanism can be integrated with the ridge forming trailer 1. At the same time, ridge forming after seeding can effectively cover the seeds, thereby effectively improving the germination rate of the seeds.

[0027] Embodiment 2:

[0028] There are three ridging openings 6, which are composed of ridging vertical plates 10 and ridging horizontal plates 11. The ridging vertical plates 10 and ridging horizontal plates 11 are fixedly connected to the tail of the ridging cabin 3. The ridging baffle 8 is provided with a translationally movable splint embedded in the ridging vertical plates 10 and the ridging horizontal plates 11. Through the setting of the translationally movable splint, the ridging baffles 8 on both sides can translate and slide on both sides of the ridging opening 6. The translationally movable splint includes a horizontally movable splint 12 and a vertically movable splint 13.

[0029] In this embodiment, the installation method of the ridging baffle 8 is further disclosed, which cooperates with the ridging vertical plate 10 and the ridging horizontal plate 11 through a translationally movable clamping plate, so that the ridging baffle 8 can slide horizontally.

[0030] Embodiment three:

[0031] A screw seat 14 and a pitch-adjusting motor 15 are also fixedly mounted on the ridging cross plate 11, a pitch-adjusting screw 16 is fixedly mounted on the driving shaft of the pitch-adjusting motor 15, an internal thread seat 17 for inserting the pitch-adjusting screw 16 is mounted on the ridging baffle 8, and the thread directions of the pitch-adjusting screws 16 on both sides of the same ridge spacing adjustment plate 7 are opposite, so that during the rotation of the pitch-adjusting screw 16, the ridging baffles 8 on both sides move toward or away from each other synchronously.

[0032] In this embodiment, a mechanism for driving the ridging baffle 8 to translate and slide is further disclosed, which drives the pitch-adjusting screw 16 to rotate through the rotation of the pitch-adjusting motor 15. Since the thread directions of the pitch-adjusting screws 16 on both sides of the same ridge-distance adjusting plate 7 are opposite, during the rotation of the pitch-adjusting screw 16, the ridging baffles 8 on both sides move toward or away from each other synchronously.

[0033] Embodiment 4:

[0034] The seeding mechanism includes a seed bucket 18, a seeding turntable 19 and a seeding baffle 20. The seed bucket 18 is fixedly installed above the seeding hole 9. The seeding turntable 19 is fixedly rotatably arranged at the bottom of the seed bucket 18. The seeding baffle 20 is fixedly installed in the ridging cabin 3 below the seeding hole 9. The seeding turntable 19 is fixedly connected to the same seeding shaft 21. The seeding shaft 21 is fixedly connected to the driving shaft of the seeding motor 22. The seeding motor 22 is fixedly installed on the ridging cabin 3. The intermittent rotation of the seeding motor 22 drives the seeding turntable 19 to rotate, thereby causing the seeds to fall from the seeding hole 9 into the seeding baffle 20. The cross-section of the seeding baffle 20 is triangular, and it moves forward synchronously with the progress of the ridging trailer 1, thereby burying the seeds that fall into it in the ridging soil.

[0035] In this embodiment, the specific structure of the seeding mechanism is further disclosed. The seeds stored in the seed bucket 18 are sown into the seeding baffle 20 by the rotation of the seeding turntable 19, and enter the soil during the sowing process. The seeding turntable 19 is a common structure in the prior art, and there are several compartments of average size inside it. The seeding turntable 19 rotates at a preset angle each time, so that the seeds in a compartment fall downward into the seeding baffle 20. The rotation of the seeding turntable 19 is achieved by the rotation of the seeding motor 22.

[0036] Embodiment five:

[0037] A gathering plate 23 is also movably installed in the ridging cabin 3. The gathering plate 23 includes a single-layer ridging plate 24 and a ridging clamp 25. The single-layer ridging plate 24 is movably inserted in the interlayer formed by the ridging clamp 25. The end of the single-layer ridging plate 24 away from the ridging clamp 25 is movably connected to the vertical movable clamp 13 through a rotating shaft 26. The end of the ridging clamp 25 away from the single-layer ridging plate 24 is fixedly connected to the inside of the ridging cabin 3 through a rotating shaft 26. During the translational sliding process of the ridging baffle 8, the gathering plate 23 performs follow-up deflection.

[0038] In this embodiment, a gathering plate 23 is also installed in the ridging chamber 3. The gathering plate 23 is deflected accordingly with the movement of the ridging baffle 8, so as to guide the loose soil after rotary tillage to the ridging mouth 6. In order to achieve the deflection of the gathering plate 23, the gathering plate 23 includes a ridging single-layer plate 24 and a ridging clamping plate 25. The normal deflection of the gathering plate 23 is achieved through the relative telescopic sliding of the two.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
