[0036] The beneficial effect of the utility model is that the pulling mechanism is conducive to pulling the fixing mechanism downward, so that the two ends of the beam of the drill seed machine are respectively tightly abutted against the side walls of the fixing mechanism and the clamping mechanism, and at the same time cooperate with the upper connecting arm mechanism and the lower connecting arm mechanism to be connected with the upper rod and the lower rod of the sowing unit respectively, thereby realizing a secure and fast connection between the sowing unit and the whole machine. When the sowing row spacing needs to be adjusted, it is only necessary to loosen the pulling mechanism and retighten the sowing unit and the different parts of the beam of the drill seed machine. The utility model can not only make the connection between the sowing unit and the whole machine secure and fast, but also realize the adjustable position of the sowing unit on the whole machine during the operation of the drill seed machine, so that the unit row spacing during sowing operations in different regions or for different crops meets the agronomic requirements, thereby maximizing the yield and benefits.

[0038] The beneficial effect of adopting the above preferred solution is that the upper connecting arm is conducive to connecting the beam of the seed drill fastened by the clamping mechanism and the fixing mechanism with the upper rod of the sowing unit, thereby achieving the purpose of fastening the sowing unit to the beam of the seed drill.

[0039] Preferably, Figure 2 and Figure 5 As shown, the lower connecting arm mechanism 2 includes two lower connecting arms 21 and two lower connecting holes 22. The two lower connecting holes 22 are through holes respectively arranged on the two lower connecting arms 21.

[0040] The beneficial effect of adopting the above preferred solution is that the lower connecting arm is conducive to connecting the beam of the seed drill fastened by the clamping mechanism and the fixing mechanism with the lower rod of the sowing unit, thereby achieving the purpose of fastening the sowing unit to the beam of the seed drill.

[0042] The beneficial effect of adopting the above preferred solution is that the clamping mechanism is a U-shaped plate structure, which is conducive to adapting and wrapping the beam of the seed drill, and cooperating with the fixing mechanism to fasten the beam of the seed drill.

[0043] Preferably, Figure 1 and Figure 2 As shown, the upper end and the lower end of the clamping mechanism 3 away from one end of the sowing unit are both provided with through holes for the fixing mechanism 4 to pass through.

[0046] The beneficial effect of adopting the above-mentioned preferred scheme is that the wedge-shaped fixed block is conducive to moving the fixed block downward by moving the pulling rod downward under the pulling action of the pulling mechanism, thereby gradually increasing the squeezing force between the fixed block and the clamping mechanism, thereby achieving a tight abutment between the beam of the seed drill and the side wall of the fixed block.

[0047] Preferably, Figure 3 and Figure 4 As shown, the circumference of the fixing block 41 is formed by a plurality of first wedge-shaped surfaces 411 and a plurality of second wedge-shaped surfaces 412 arranged alternately, wherein the first wedge-shaped surfaces 411 are inclined planes, and the second wedge-shaped surfaces 412 are inclined arc surfaces.

[0048] Among them, it should be noted that: Figure 4 As shown, in a preferred embodiment of the present utility model, the number of the first wedge-shaped surfaces 411 and the number of the second wedge-shaped surfaces 412 are both four.

[0049] The beneficial effect of adopting the above-mentioned preferred scheme is that multiple first wedge surfaces and multiple second wedge surfaces are conducive to forming a wedge-shaped structure that is larger at the top and smaller at the bottom, so that during the downward movement of the fixed block, the extrusion force between the fixed block and the clamping mechanism is gradually increased, thereby achieving a tight abutment between the beam of the seed drill and the side wall of the fixed block.

[0050] Preferably, Figure 2As shown, under the pulling action of the pulling mechanism 5, the two ends of the beam of the seed drill are respectively in contact with the first wedge surface 411 and the inner wall of the clamping mechanism 3.

[0051] The beneficial effect of adopting the above preferred solution is that it is conducive to fastening the beam of the seed drill by the second wedge surface and the clamping mechanism on the fixed block, thereby improving the stability of the sowing unit when working on the seed drill.

[0052] Preferably, Figure 3 As shown, the pulling rod 42 includes a first pulling rod 421 and a second pulling rod 422.

[0054] Preferably, Figure 1 and Figure 2 As shown, the pulling mechanism 5 is a block structure that is penetrated by the second pulling rod 422 and is threadedly connected to the second pulling rod 422 .

[0055] It should be noted that: in the preferred embodiment of the present utility model, the pulling mechanism 5 is a bolt.

[0056] The beneficial effect of adopting the above preferred solution is that the pulling mechanism is threadedly connected to the second pulling rod, which is conducive to the pulling mechanism moving up and down on the second pulling rod, thereby adjusting the up and down position of the fixing block.

[0057] The working process of the utility model is described below by an embodiment:

[0058] like Figures 1 to 5 As shown, when it is necessary to clamp the beam of the seed drill, the pulling mechanism 5 is rotated to make the pulling mechanism 5 move upward on the second pulling rod 422. Then, correspondingly, the fixing block 41 will be pulled downward by the pulling rod 42, thereby moving downward. Since the fixing block 41 is a wedge-shaped structure, during the downward displacement of the fixing block 41, the squeezing force between the fixing block 41 and the inner wall of the through hole at the upper end of the clamping mechanism 3, and between the fixing block 41 and the beam of the seed drill gradually increases. When the pulling mechanism 5 cannot continue to move upward on the second pulling rod 422, it means that at this time, the two ends of the beam of the seed drill are respectively tightly abutted against the inner wall of the clamping mechanism 3 and the first wedge surface 411 of the fixing block 41, thereby achieving clamping.

[0059] Then, the upper connection hole 12 on the upper connection arm 11 is connected to the connection hole at the upper rod end of the sowing unit by bolts, and the lower connection hole 22 on the lower connection arm 21 is connected to the connection hole at the lower rod end of the sowing unit by bolts, so as to connect the clamped beam of the seed drill to the sowing unit;

[0060] When adjusting the sowing row spacing, rotate the pulling mechanism 5 to move downward on the second pulling rod 422, so that the downward pulling force on the wedge-shaped fixing block 41 is reduced or eliminated. At this time, the clamping mechanism 3 can be moved to different positions of the beam of the seed drill for re-clamping.

[0061] The clamping mechanism of the utility model is non-permanently connected to the beam of the seed drill. The clamping mechanism and the wedge-shaped fixing block can move relatively to ensure the contact and separation between the clamping mechanism and the beam of the seed drill. Different positions of the beam of the seed drill are installed on the clamping mechanism, thereby realizing the adjustment of the row spacing of the single unit of the seed drill.
