Technical Field

[0001] The invention relates to the technical field of sowing machines for planting agriculture, in particular to a sowing machine with a swingable seed box. Background Art

[0002] Machine sowing often encounters problems such as low seed adsorption rate and difficulty in sowing irregular seeds. This problem directly leads to a high empty seed rate. Among them, the empty seed rate of irregular flower seeds is as high as 30%. The main reason for this problem is that seed adsorption is the instantaneous force between the air suction hole and the seed. The air suction hole can only complete effective adsorption when the contact area with the seed is large enough. However, the distribution of seeds in the seed box itself is random. The purpose of vibration is to increase the movement of seeds. Therefore, round seeds have high mobility and are easy to adsorb, but irregular seeds have poor mobility and low adsorption rate.

[0003] Therefore, a new type of seed drill is badly needed on the market to solve the above problems. Summary of the invention

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

[0022] The object of the present invention is to provide a seeder with a swingable seed box, which is used to solve the technical problems existing in the above-mentioned prior art, increase the vibration effect of the seeds, and thus enhance the adsorption effect of the seeds.

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1-4 As shown, this embodiment provides a seed drill with a swingable seed box, including a seed drill body, a seed suction drum 7 rotatably connected to the seed drill body, and a plurality of seed suction holes on the seed suction drum 7, and also includes a swing reduction motor 1, an eccentric wheel 2, a swing rod 3 and a seed box 4. The swing reduction motor 1 is fixed to the seed drill body, and the output shaft of the swing reduction motor 1 is fixed to the center of the first surface of the eccentric wheel 2, and the swing reduction motor 1 provides power for the rotation of the eccentric wheel 2. The second surface of the eccentric wheel 2 is provided with an eccentric shaft hole, one end of the swing rod 3 is relatively fixed to the eccentric shaft hole, and the length direction of the swing rod 3 is perpendicular to the axial direction of the eccentric shaft hole. The swing rod 3 can be driven to move horizontally by the rotation of the eccentric wheel 2. As the swing rod 3 moves left and right, the swing rod 3 and the seed drill body also slide relatively. The seed box 4 is relatively fixed to the swing rod 3, and the seed box 4 is against the seed suction drum 7. The structure of the seed box 4 is set according to the size of the seed suction drum 7, as long as it can match the seed suction drum 7.

[0025] When in use, first start the swing reduction motor 1 and the seed suction drum 7. Since the seed suction drum 7 is in contact with the seed box 4, the seed box 4 will vibrate in a direction perpendicular to the axial direction of the seed suction drum 7. The swing reduction motor 1 drives the eccentric wheel 2 to rotate. The rotation of the eccentric wheel 2 will drive the swing rod 3 to move back and forth left and right (where the swing rod 3 will also move up and down due to the eccentric motion, but the up and down movement is small and can be ignored). Thereby, the swing rod 3 drives the seed box 4 to move back and forth left and right, thereby increasing the adsorption area of ​​the seeds. The seed suction drum 7 is provided with an air pump. The air pump is set with negative pressure to effectively adsorb the seeds in the seed box 4 on the surface of the seed suction hole. When the seeds reach the upper surface of the hole plate as the seed suction drum 7 rotates, the air pump is set with positive pressure to sow the seeds quantitatively and accurately into each hole of the hole plate.

[0026] In order to fix the swing rod 3 to the planter body, in this embodiment, two limit rod frames 6 are also included. The two limit rod frames 6 are respectively located at the two ends of the swing rod 3. The first end of the limit rod frame 6 has four through holes. The two ends of the swing rod 3 pass through the through holes on both sides respectively. Those skilled in the art can choose which through hole the swing rod 3 is inserted into according to actual needs. The second end of the limit rod frame 6 is fixed to the planter body. The function of the limit rod frame 6 is to limit the swing rod 3, so that the swing rod 3 can only move along the axis direction of the through hole.

[0027] In order to make the length direction of the swing rod 3 perpendicular to the axis direction of the eccentric shaft hole, the present embodiment further includes a screw rod 10, a fixing member and two fisheye joints 9, the rod parts of the two fisheye joints 9 are respectively fixed to the two ends of the screw rod 10, the fisheye parts of the two fisheye joints 9 are respectively rotatably connected to the eccentric shaft hole and the first end of the fixing member, and the second end of the fixing member is fixed to the end of the swing rod 3 close to the swing reduction motor 1. For the connection between the fisheye part and the eccentric shaft hole, an eccentric rod can be provided, and the eccentric rod can penetrate the fisheye part and the eccentric shaft hole at the same time and be fixed thereto, or it can be directly welded, as long as the fisheye part and the eccentric shaft hole can be fixed.

[0028] Further, in this embodiment, both ends of the screw rod 10 have external threads, the rod part of the fisheye joint 9 has internal threads, and the fisheye joint 9 is threadedly connected to the screw rod 10. The fisheye joint 9 can be purchased on the market, and the model size can be selected according to actual needs.

[0029] As for the structure of the fixing part, in this embodiment, the fixing part includes a connecting rod 8 and a ring 11. The first end of the connecting rod 8 is fixed to the fisheye part of the fisheye joint 9 away from one end of the swing reduction motor 1, and the second end of the connecting rod 8 is fixed to the ring 11. The outer ring of the swing rod 3 has an external thread, and the inner ring of the ring 11 has an internal thread. One end of the swing rod 3 is threadedly fixed to the inner ring of the ring 11. Threaded holes can also be set at corresponding positions of the swing rod 3 and the ring 11, and then fixed by screws.

[0030] In order to achieve the relative fixation of the seed box 4 and the swing rod 3, the present embodiment also includes two hooks 5. Both ends of the swing rod 3 have annular grooves. The first end of the hook 5 is relatively fixed to the seed box 4, and the second end of the hook 5 is hung on the annular groove. The groove can prevent the seed box 4 from moving left and right relative to the swing rod 3, and can also make the seed box 4 vibrate due to the rotation of the seed suction roller 7.

[0031] In order to achieve the fixation of the hook 5 and the seed box 4, the present embodiment also includes two connecting plates, the first ends of the two connecting plates are respectively fixed to the two ends of the seed box 4, the second end of the connecting plate is fixedly connected to the first end of the hook 5, and the side of the connecting plate in contact with the seed suction roller 7 is an arc structure, which is in full contact with the seed suction roller 7.

[0032] The present specification uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
