[0008] As a further improvement of this utility model, the rear connecting rod is provided with a first mounting hole at the position where the connecting bolt is set, and the fixed support is provided with two second mounting holes, one above the other. The first mounting hole on the rear connecting rod and one of the second mounting holes on the fixed support are connected by a connecting bolt.
[0009] As a further improvement of this utility model, a handle is fixedly connected to the upper end of the adjusting threaded rod.
[0010] As a further improvement of this utility model, the sleeve is threaded with a plurality of first tightening bolts that can be tightened against the rectangular adjusting rod, and the sleeve is locked onto the rectangular adjusting rod by the first tightening bolts.
[0011] As a further improvement of this utility model, each support tube is threaded with multiple second tightening bolts that can be tightened against the fixed rod, and the support tube is locked to the fixed rod through the second tightening bolts.
[0012] Compared with the prior art, this utility model has the following advantages:
[0013] 1. By setting a rectangular adjusting rod with two adjustable sleeves, and fixing a support tube at the lower end of the sleeves, an adjustable fixing rod is connected to the support tube. The fixing rod is fixed to the soil covering disc. Therefore, by adjusting the length of the fixing rod inside the support tube, the vertical height of the soil covering disc can be adjusted. By sliding and adjusting the two sleeves on the rectangular adjusting rod, the distance between the two soil covering discs can be adjusted according to the actual soil covering situation. This makes it suitable for sowing and soil covering in planting furrows of different widths and for different seeds, thus broadening its practical application.
[0014] Furthermore, by setting a fixed support, and having an adjustable connector on the fixed support, the angle between the connector and the fixed support can be adjusted, thus allowing for more flexible adjustment of the soil entry angle of the circular plate according to the actual situation.
