Description

Technical Field

[0002] Row seeding technology is a kind of agronomy for many crops, such as wheat, alfalfa, rapeseed, etc. The row spacing between different crops and the same crops in different regions is not exactly the same. Scientific and reasonable row spacing during sowing can ensure a higher grain yield and obtain better economic benefits. The drill seeder is the main machine for sowing such crops.

[0033] The beneficial effect of the utility model is that the pulling mechanism is conducive to causing the elastic plate to deform in the direction of the clamping mechanism, thereby fastening the sowing unit to the beam of the drill seed machine. At the same time, when the sowing row spacing needs to be adjusted, it is only necessary to loosen the pulling mechanism and retighten the sowing unit to 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 firm 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 profit.

[0035] The beneficial effect of adopting the above preferred scheme is that under the pulling action of the pulling mechanism, the clamping plate cooperates with the elastic plate to facilitate the fast connection between the sowing unit and the beam of the drill seed machine, and the pulling force plate is conducive to providing a force position for the installation and pulling of the pulling mechanism.

[0036] Preferably, Figure 1 and Figure 2 As shown, a mounting hole 33 is provided at one end of the upper end of the clamping plate 31 away from the upper connecting arm mechanism 1 , and the mounting hole 33 is a through hole, and the elastic plate 4 is adapted to pass through the mounting hole 33 .

[0038] Preferably, Figure 1 and Figure 2 As shown, the elastic plate 4 is a plate-shaped structure with a bent upper end, and the pulling mechanism 5 passes through the lower end of the elastic plate 4 .

[0039] The beneficial effect of adopting the above preferred solution is that the bending of the upper end of the elastic plate helps to prevent the elastic plate from falling directly when it passes through the mounting hole and the lower end has not yet been passed through by the pulling mechanism.

The pulling rod 51 is a rod-shaped structure with threads on its outer circumference. The pulling rod 51 passes through the pulling block 52 and is threadedly connected to the pulling block 52 .

[0041] The beneficial effect of adopting the above preferred solution is that the pulling rod is threadedly connected to the pulling block, which is conducive to displacing the pulling block on the pulling rod toward the pulling force plate, thereby deforming the elastic plate and applying a squeezing force to the beam of the seed drill.

[0043] The beneficial effect of adopting the above preferred solution is that the pulling rod passes through the lower end of the elastic plate, which is conducive to causing the elastic plate to deform toward the beam of the seed drill under the displacement action of the pulling block.

[0044] Preferably, Figure 2 As 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 inner wall of the clamping plate 31 and the elastic plate 4.

[0045] It should be noted that in the technical solution of the present invention, the width of the beam of the drill is adapted to the distance from the inner wall of the clamping plate 31 to the elastic deformation range of the elastic plate 4, so as to avoid the inability to securely connect the sowing unit to the beam of the drill due to the width of the beam of the drill being too large or too small.

[0046] The beneficial effect of adopting the above preferred solution is that it is conducive to fastening the sowing unit to the beam of the seed drill.

[0047] Preferably, Figure 2 and Figure 3 As shown, the upper connecting arm mechanism 1 includes an upper connecting arm 11 and an upper connecting hole 12. The upper connecting arm 11 is a plate-like structure fixedly mounted on the upper end of the clamping plate 31. The upper connecting hole 12 is a through hole arranged at one end of the upper connecting arm 11 away from the clamping plate 31. The upper rod of the sowing unit is connected to the upper connecting arm 11 through bolts and the upper connecting hole 12.

[0048] 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 clamped by the clamping plate and the elastic plate with the upper rod of the sowing unit, thereby achieving the purpose of fastening the sowing unit to the beam of the seed drill.

[0049] Preferably, Figure 2 As shown, the lower connecting arm mechanism 2 includes two lower connecting arms 21 and a reinforcing connecting plate 22.

[0051] Preferably, Figure 2 and Figure 3 As shown, a lower connecting hole 211 is provided at one end of the lower connecting arm 21 away from the clamping plate 31 . The lower connecting hole 211 is a through hole. The lower rod of the sowing unit is connected to the lower connecting arm 21 through bolts and the lower connecting hole 211 .

[0052] 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 clamped by the clamping plate and the elastic plate with the lower rod of the sowing unit, thereby achieving the purpose of fastening the sowing unit to the beam of the seed drill.

[0053] The working process of the utility model is described below by an embodiment:

[0054] like Figures 1 to 3As shown, when the beam of the drill needs to be clamped, the pulling block 52 is rotated to displace the pulling block 52 on the pulling rod 51 toward the beam of the drill. In this process, the pulling block 52 applies a squeezing force to the lower end of the elastic plate 4, and the lower end of the elastic plate 4 undergoes elastic deformation and transmits this squeezing force to the beam of the drill, thereby squeezing the beam of the drill toward the inner wall of the clamping plate 31. When the pulling block 52 no longer rotates on the pulling rod 51, it indicates that the beam of the drill has been clamped by the elastic plate 4 and the inner wall of the clamping plate 31.

[0055] 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 211 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;

[0056] When adjusting the sowing row spacing, the pulling block 52 is displaced on the pulling rod 51 in the direction away from the beam of the drill, so that the elastic plate 4 and the clamping plate 31 release the beam of the drill, and then the elastic plate 4 and the clamping plate 31 are clamped again on different parts of the beam of the drill.

[0057] The connection between the clamping mechanism and the beam of the drill seed machine is non-permanent. The elastic plate is deformed under the action of the pulling mechanism. The elastic plate provides forces in opposite directions to the clamping mechanism and the beam of the drill seed machine, so that the beam of the drill seed machine is in close contact with the clamping mechanism. When the effect of the pulling mechanism disappears, the beam of the drill seed machine is separated from the clamping mechanism, thereby realizing the adjustment of the single-unit row spacing.
