[0002] The disc seed leg is a component of the seeder. Its main function is to support the seeds during the sowing process and ensure that the seeds are accurately placed in the soil at the predetermined depth and spacing. The disc seed leg is usually composed of disc-shaped metal parts that can rotate as the seeder moves to achieve an even distribution of seeds. In addition, the disc seed leg can also help break up the hard layer on the soil surface, making it easier for the seeds to enter the soil and improve the success rate of sowing.
[0003] However, the existing disc seed legs often encounter the following problems during use: the sowing depth of the existing disc seed legs cannot be adjusted. In the case of large terrain fluctuations or different soil hardness, the sowing depth will be uneven, resulting in uneven seed germination rate and growth conditions. Utility Model Content

[0028] 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.
[0029] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "set", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0030] like Figure 1-3 As shown, a disc seed leg depth adjustment structure includes: side plate 1, fixed plate 2, screw rod 3, nut 4, slideway 5, slider 6, connecting plate 7, and slideway strip 8. The fixed plate 2 is fixedly installed below the top edge of the side plate 1. The fixed plate 2 is used to fix the position of the entire adjustment device to ensure that the device remains stable during the adjustment process. The screw rod 3 is inserted through the top of the side plate 1. The screw rod 3 is the main moving part of the adjustment device. It changes its height relative to the fixed plate 2 by rotating, thereby achieving depth adjustment. The nut 4 is sleeved on the rod body of the screw rod 3, and the nut 4 is located below the fixed plate 2. The slideway 5 is opened on the plate body of the side plate 1, and the slider 6 is located on one side of the slideway 5. The bottom of the screw rod 3 is inserted through the connecting plate 7. One side of the connecting plate 7 passes through the slideway 5 and is fixedly connected to the slider 6. The setting surface of the slider 6 is not on the same side as the setting surface of the connecting plate 7. There are two slideway strips 8, and the two slideway strips 8 are located on both sides of the connecting plate 7.
[0031] In this embodiment, Figure 2-3 As shown, in order to prevent the nut 9 from being sleeved on the top of the screw rod 3, two rows of plug-in holes 10 are provided, and the two rows of plug-in holes 10 are respectively arranged on both sides of the slide 5, and the surface of the slide bar 8 is provided with a protrusion, and the protrusion of the slide bar 8 is fixed by passing through the plug-in holes 10. The setting of the slide bar 8 and the plug-in holes 10 further enhances the stability of the movement of the connecting plate 7. The plug-in holes 10 are passed through the slide bar 8 with protrusions to ensure the accuracy and reliability of the movement of the connecting plate 7 on the slide 5. In this way, the connecting plate 7 will avoid the deviation caused by vibration or shaking when sliding. The external thread 11 is opened at the bottom end of the screw rod 3, and the external thread 11 at the bottom end of the screw rod 3 is used to tighten the connection port of the disc seed leg, so that the adjustment device can be firmly connected to the disc seed leg.
[0032] It should be noted that the disc seed leg depth adjustment structure designed by the utility model, when in use, the external thread 11 at the bottom end of the screw rod 3 is tightened and connected with the connection port of the disc seed leg, and then the nut 4 is loosened, the screw rod 3 will fall, and the falling of the screw rod 3 will drive the connecting plate 7 and the slider 6 to fall. The connecting plate 7 will not deviate during the falling process due to the limitation of the slide bars 8 on both sides. After falling to the appropriate position, tighten the nut 4 to complete the depth fixation. At this time, tighten the nut 9 at the top to lock the screw rod 3 after the adjustment is completed to prevent it from deviating due to vibration or other reasons during use. At this point, the use process ends.
[0033] Although the embodiments of the present invention have been shown and described, it will be apparent to those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
