Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural planting technology, and in particular to an agricultural planting soil covering machine. Background Technology
[0002] Crop farming is a major component of agriculture, characterized by using land as the basic means of production and utilizing the biological functions of crops to convert solar energy into chemical potential energy and agricultural products. Essentially, it utilizes the photosynthesis of green plants to synthesize organic matter from carbon dioxide, water, and minerals, converting solar energy into chemical energy stored within it. This forms the material basis for plant products, food, and human life activities. In agricultural planting, it is usually necessary to cover crop seeds with soil from both sides after sowing, so that the soil can protect the buried seeds and promote germination. Existing soil covering devices are mostly used in conjunction with agricultural machinery, completing the soil covering work by turning over the soil around the seeds. This method only completes the soil covering of the seeds, but because the soil becomes loose after turning, the contact between the soil and the seeds is not close enough, reducing the efficiency of water absorption by the seeds and thus affecting seed growth. Utility Model Content
[0003] The purpose of this invention is to provide an agricultural planting and covering machine to solve the above-mentioned problems.
[0004] This utility model achieves the above objectives through the following technical solutions:

A fixed shaft is fixed to each roller frame, and rollers are mounted on the fixed shaft. The machine also includes a soil covering mechanism, which includes a support frame fixed to the support frame. Left and right helical screws are mounted on the support frame, and threaded seats are mounted opposite each other on the left and right helical screws. An L-shaped plate is fixed to the lower end of the threaded seat, and a soil covering shovel is fixed to the L-shaped plate. An adjusting handwheel is fixed to one end of each helical screw. A compaction mechanism is provided on one side of the soil covering mechanism. The compaction mechanism includes a screw rod and two sets of guide rods mounted on the support frame. An installation plate is mounted to the lower end of the screw rod, and a U-shaped plate is mounted on the lower surface of the installation plate. A rotating shaft is mounted on the U-shaped plate, and a flattening roller is fixed to the rotating shaft. A lifting handwheel is fixed to the upper end of the screw rod. Two sets of fixing blocks are fixed opposite each other on one side of the support frame, and multiple sets of fixing bolts are mounted opposite each other on the fixing blocks.
[0006] Further configuration: The roller is rotatably connected to the fixed shaft.
[0007] Further configuration: The left and right helical screws are rotatably connected to the support frame, and the threaded seat is connected to the left and right helical screws by a thread.
[0008] Further configuration: The screw and the bracket are connected by a thread, the guide rod and the bracket are slidably connected, the screw and the mounting plate are rotatably connected, and the rotating shaft and the U-shaped plate are rotatably connected.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] By setting up a compaction mechanism, shaking the lifting handwheel drives the screw to rotate. Under the interaction between the screw and the support, the lower flattening roller moves up and down. The height of the flattening roller can be adjusted to achieve different degrees of soil compaction, thereby making the soil and seeds in close contact, improving the efficiency of seed water absorption in the soil, and ensuring the seed growth environment.
