[0044] Specific implementation process: the depth limiting structure of the ditching fertilizer machine is supported by the depth limiting wheel 3 rolling on the ridge ditch, which is simple in structure and low in cost. When in use, the worker adjusts the height and width of the traveling wheel 2, erects the ditching fertilizer machine on the ridge 9 (the traveling wheels 2 on both sides of the ditching fertilizer machine are erected on the ridge ditch passages on both sides of the ridge 9), supports the depth limiting wheel 3 on the front side of the ditching fertilizer machine on the ridge 9, and adjusts the position of the mud scraping plate 112.

[0045] In summary, the depth limiting structure of the ditching fertilizer machine is supported by the depth limiting wheel rolling on the ridge ditch, which is simple in structure and low in cost. When in use, the worker erects the ditching fertilizer machine on the ridge, the traveling wheels on both sides of the ditching fertilizer machine are erected on the ridge ditch passages on both sides of the ridge, the depth limiting wheel on the front side of the ditching fertilizer machine is supported on the ridge, and the depth limiting wheel rolls on the ridge ditch when the ditching fertilizer machine moves forward. If the traveling wheels on both sides sink when encountering muddy ground, the depth limiting wheel supports on the top of the ridge to assist the traveling wheels in supporting the main body of the ditching machine, so as to prevent the ditching fertilizer machine from sinking and to ensure the consistency of the ditching depth as much as possible. The depth limiting wheel is detachably connected with the main body of the ditching machine through the supporting plate, which is convenient for maintenance or replacement of depth limiting wheels of different sizes in different environments, and improves the versatility and practicality. The height of the depth limiting wheel can be adjusted by locking different height limiting holes through bolts, so as to cope with different working environments. The presence of the supporting plate can scrape the mud on the depth limiting wheel, so as to prevent the mud from adhering to the depth limiting wheel during the movement process, so that the cross-sectional radius of the depth limiting wheel becomes larger due to the adhesion of the mud, which leads to the inconsistency of the ditching depth. The angle of the mud scraping plate can be adjusted through the transverse addition, so as to cope with different use scenarios. When the depth limiting wheel of different cross-sectional radius is replaced, the angle of the mud scraping plate needs to be adjusted to change the distance between the mud scraping plate and the depth limiting wheel. The wheel shaft is matched with the shaft groove, that is, the wheel shaft is clamped on the shaft groove of different heights, so as to facilitate the adjustment of the height of the depth limiting wheel. The wheel shaft is further reinforced through the cooperation of the fixing piece and the clamping groove, so that the wheel shaft is more stable. The wheel shaft is prevented from falling off from the clamping groove due to shaking during the movement process. The transverse adjustment pipe is matched with the horizontal rod, so as to adjust the distance between the traveling wheels and cope with ridges of different widths. The vertical adjustment pipe is matched with the vertical rod, so as to adjust the height of the traveling wheels and cope with ridges of different heights. The height of the vertical rod is adjusted by rotating the adjusting handle, which is more labor-saving.
