Detailed Description

The technical contents of the preferred embodiments of the present invention will be more clearly and easily understood by referring to the drawings attached to the specification. The present invention may be embodied in many different forms of embodiments and the scope of the invention is not limited to the embodiments set forth herein.

As shown in fig. 1, in one embodiment according to the present invention, the soil fertilization system 100 is suspended and towed by a towing system, such as a high horsepower tractor 200, and provides a source of power, while liquid manure from a manure pit is pumped to the soil fertilization system 100 through a towing hose 300. In operation, the under soil fertilization system 100 is mounted on the rear of the tractor 200, the tractor 200 is used to haul the under soil fertilization system 100 to the cultivated land or the grassland, one end of the towing hose 300 is connected to the under soil fertilization system 100, the other end of the towing hose 300 is connected to a rotor pump disposed beside the septic tank, and liquid manure is delivered to the under soil fertilization system 100. A driver controls the liquid fertilizer distributor 110 to operate at the tractor 200, and simultaneously lowers the under-soil fertilization system 100 to a required depth through the rear suspension lifting function, and starts ditching and fertilizing operation of 50-100mm under soil on cultivated land and grassland.

Fig. 2 is a schematic view of the main frame structure of the under soil fertilization system 100 when the liquid fertilizer distribution hose is not shown, and referring to fig. 3 and 4 when the liquid fertilizer distribution hose is shown, it can be seen that the main frame structure includes a middle frame structure 101, a left side frame structure 102, and a right side frame structure 103. A row of ditching ploughshares 107 are arranged below the main body frame structure. The ditching ploughshare 107 is preferably made of 65Mn spring steel, so that when firm sundries such as stones in soil are encountered during the operation of ploughing or grassland, the ditching ploughshare 107 can avoid the firm sundries through the spring steel elasticity principle so as to avoid damage. A soil crushing roller 105 is also provided behind the middle frame structure 101, the left and right

side frame structures

102, 103. The soil crushing roller 105 is mounted on the main frame structure of the under soil fertilization system 100 by a pressing spring 106. During operation, after the ditching ploughshare 107 ditches, the ditched soil is fertilized through the liquid fertilizer distribution hose 108, and then the soil crushing roller 105 crushes and seals the soil turned up by the ploughshare 107, so that the liquid fertilizer is isolated from the air, and nutrition volatilization is avoided. The soil crushing roller 105 can move up and down along with the soil terrain through the pressure spring 106, and the soil sealing effect is guaranteed. The left side frame structure 102 and the right side frame structure 103 can be folded left and right to open and retract under the drive of the hydraulic cylinder 104.
