[0021] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The function of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model. However, it should not be construed as a limitation on the protection scope of the present utility model.

[0022] Referring to Figures 1-4 , an adjustable ditch opener for a pneumatic seeder according to an embodiment of the present utility model includes a cross bar 1. A plurality of sleeve plates 2 are equidistantly arranged on the outer side of the cross bar 1. First connecting plates 3 are arranged on the front sides of the plurality of sleeve plates 2. Ditch opening assemblies are arranged at the bottoms of the plurality of first connecting plates 3. The ditch opening assembly includes a ditch opener 4 fixedly connected to the bottom of the first connecting plate 3, two mounting frames 10 symmetrically and fixedly connected to the rear side of the ditch opener 4 and arranged in a C-shaped structure, two rotating shafts 11 rotatably connected to the inner sides of the corresponding mounting frames 10, two soil dividing plates 5 fixedly connected to the outer sides of the rotating shafts 11, a fixed plate 6 fixedly connected to the rear side of the ditch opener 4 and located between the two mounting frames 10, a movable plate 8 slidably connected to the inside of the fixed plate 6, two second connecting plates 9 symmetrically and rotatably connected to both sides of the movable plate 8, and a first screw 7 threadedly connected to the end of the fixed plate 6 and opposite to the ditch opener 4. One ends of the two second connecting plates 9 opposite to the movable plate 8 are rotatably connected to the corresponding soil dividing plates 5. One end of the first screw 7 close to the movable plate 8 is rotatably connected to the outer side of the movable plate 8;

[0023] When it is necessary to adjust the ditch opening width, rotating the first screw 7 can realize the forward and backward movement operation of the first screw 7. Under the movement of the first screw 7, the movable plate 8 can be driven to move. Under the action of the moving movable plate 8, the ends of the second connecting plates 9 close to each other can be better driven to move towards or away from each other, so as to better drive the soil dividing plates 5 to expand outwards or contract inwards, and then the adjustment of the ditch opening width can be completed to meet different seeding requirements. The operation is convenient, the adjustment of the ditch opener can be quickly realized, and the seeding efficiency is improved.

[0024] Second screws 12 are threadedly connected to the inner sides of the plurality of sleeve plates 2 and opposite to the first connecting plates 3. One ends of the plurality of second screws 12 close to the cross bar 1 are in contact with the outer side of the cross bar 1. The sleeve plates 2 slidably connected to the outer side of the cross bar 1 are fixedly connected to the cross bar 1 through the second screws 12. The movable connection mode facilitates adjusting the horizontal position of the sleeve plates 2 on the cross bar 1 by rotating the second screws 12, so as to adjust the distance between adjacent two ditch openers 4 to adjust the seeding spacing.

[0025] A plurality of first connecting plates 3 are all connected to the corresponding sleeve plates 2 through adjusting components. The adjusting components include a plurality of adjusting holes 13 equidistantly formed inside the first connecting plate 3 and a third screw 14 inserted into one of the adjusting holes 13. The third screw 14 is threadedly connected to the inside of the sleeve plate 2. The first connecting plate 3 is connected to the sleeve plate 2 through the adjusting hole 13 and the third screw 14, which facilitates the disassembly of the first connecting plate 3 so that the third screw 14 is connected in cooperation with the adjusting holes 13 at different height positions, thereby facilitating the adjustment of the distance between the ditching shovel 4 and the cross bar 1 to adjust the ditching depth.

[0026] A second screw 12 is also threadedly connected inside a plurality of sleeve plates 2 and above the cross bar 1. Two groups of second screws 12 are provided for the connection work between the sleeve plate 2 and the cross bar 1, which is beneficial to ensuring the stability of the connection between the sleeve plate 2 and the cross bar 1.

[0027] The rear sides of a plurality of ditching shovels 4 are all arranged in an outwardly expanding eight-shaped structure. The arranged eight-shaped structure can block the area between the ditching shovel 4 and the mounting frame 10, so as to better guide the soil to the side of the soil dividing plate 5 through the inclined surface of the eight-shaped structure.

[0028] Working principle: When it is necessary to adjust the ditching width, rotating the first screw 7 can realize the forward and backward movement operation of the first screw 7. Under the movement of the first screw 7, the movable plate 8 can be driven to move. Under the action of the moving movable plate 8, the closer ends of the second connecting plates 9 can be better driven to move towards each other or away from each other, thereby better driving the soil dividing plate 5 to expand outward or contract inward, and then the adjustment work of the ditching width can be completed;

[0029] When it is necessary to adjust the ditching depth, disassemble the first connecting plate 3 so that the third screw 14 is connected in cooperation with the adjusting holes 13 at different height positions, thereby facilitating the adjustment of the distance between the ditching shovel 4 and the cross bar 1 to adjust the ditching depth;

[0030] When it is necessary to adjust the ditching spacing, rotate the second screw 12 to adjust the horizontal position of the sleeve plate 2 on the cross bar 1, thereby adjusting the distance between two adjacent ditching shovels 4 to adjust the sowing spacing; By adjusting the ditching width, depth and spacing, it is convenient to flexibly adjust according to different soil conditions and sowing requirements, improve the adaptability and sowing effect of the seeder, and the operation is convenient, the adjustment of the ditching device can be quickly realized, and the sowing efficiency is improved.

[0031] The above has described the embodiments of the present invention in detail with reference to the drawings, but the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the technical field, various changes can also be made without departing from the purpose of the present invention.
