[0002] At present, the quantitative fertilization device for trees is to hang an infusion bag on the trunk of each tree. The nutrient solution in the infusion bag enters the trunk through the infusion needle, and then is transmitted from the trunk to other parts such as roots, branches and leaves. Obviously, the trunk obtains the most nutrients, while the roots that need nutrients the most obtain less nutrients, which affects the fertilization efficiency. Summary of the invention

[0003] In order to solve the above technical problems, the object of the present invention is to provide a vehicle-mounted injection quantitative fertilization device for fertilizing tree roots.

[0004] The object of the present invention is achieved in that it comprises a rotatable drilling device, an air and fertilizer supply device and a trailer (unpowered vehicle);

[0005] The rotatable drilling device is composed of a rotary drive device, a plurality of folding mechanical arms and a drilling device. The drilling device is composed of a drilling hydraulic cylinder, a drill bit and its guide rail device. The drill bit is composed of a pneumatic pick, a tubular drill and a connecting block. The pneumatic pick includes a pneumatic pick body and a pneumatic pick drill bit (the pneumatic pick drill bit mentioned in this article refers to the drill bit remaining after cutting off a section from a standard pneumatic pick drill bit). The pneumatic pick drill bit, the connecting block and the tubular drill bit are rigidly connected in sequence from top to bottom. The rigid connection between the pneumatic pick drill bit and the connecting block means that the pneumatic pick drill bit is inserted into the blind hole of the connecting block from above for installation and fixation. The lower half of the connecting block has an arc-shaped tube cavity. The inlet of the arc-shaped tube cavity is located on the side end face of the connecting block, and the outlet is located on the lower end face of the connecting block. The rigid connection between the connecting block and the tubular drill bit means that the tubular The upper end of the drill is inserted into the outlet of the arc-shaped tube cavity for installation and fixation. A radial nozzle is provided at the lower end of the tubular drill, and the radial nozzle is communicated with the tube cavity of the tubular drill. The guide rail device is composed of a column-type guide rail and a guide rail sleeve. The column-type guide rail is located between the drill bit and the vertical drilling hydraulic cylinder, wherein the cylinder body of the vertical drilling hydraulic cylinder is at the bottom, and the lower end of the column-type guide rail and the cylinder body of the drilling hydraulic cylinder are both fixed on the base. The guide rail sleeve is rigidly connected to the pneumatic pick body and the connecting block, and the upper end of the guide rail sleeve is hinged to the piston rod of the drilling hydraulic cylinder. The rotary drive device includes a hydraulic motor, a worm gear mechanism, a rotary bearing and a rotary disk. The base of the drilling device, a plurality of folding mechanical arms and the rotary disk of the rotary drive device are connected in sequence, and the rotary drive device is installed on a trailer.

[0006] The air and fertilizer supply device comprises an injection-type liquid fertilizer feeding device, an air compressor (air pump) and a liquid and gas transmission pipeline. The main body of the injection-type liquid fertilizer feeding device is a short tube with an outer square and an inner circle, a syringe and a fertilizer hydraulic cylinder, which are connected by flanges in sequence from front to back. The outer end (front end) of the piston rod of the fertilizer hydraulic cylinder is connected and fixed to the syringe piston, and the axial outlet of the short tube is sealed by a hexagonal screw plug. A radial liquid outlet and a radial liquid suction port are respectively opened on the two outer walls of the short tube. The liquid outlet and the liquid suction port are both connected to the short tube cavity. A liquid outlet valve and a tee are installed in sequence at the liquid outlet. The other two interfaces of the tee are respectively connected to the gas / liquid pipeline and the air inlet pipeline. The other end of the air inlet pipeline is connected to the air compressor (air pump), and the other end of the gas / liquid pipeline is connected to the inlet of the arc-shaped tube cavity of the connecting block; a liquid suction pipe joint with a liquid suction valve is connected to the liquid suction port, and the liquid suction pipeline is connected between the liquid fertilizer box and the liquid suction pipe joint;

[0007] The air compressor, liquid fertilizer tank and air and fertilizer supply device are all installed on the trailer.

[0008] The operation process of the present invention is drilling a hole → loosening the soil by jetting air into the hole → fertilizing the hole. Specifically, the trailer of the present invention is towed to the operation site by a motor vehicle such as a tractor, the rotary drive device and a plurality of folding mechanical arms are started, and the tubular drill is pointed at the ground less than one meter away from the trunk of the tree and toward the root of the tree; the suction valve is opened, the fertilizer hydraulic cylinder is started, and its piston rod is retracted, driving the syringe piston to move backward, and the liquid fertilizer is sucked into the syringe through the suction line, and the fertilizer hydraulic cylinder and the suction valve are closed; the drilling hydraulic cylinder is started, and its piston rod is retracted, that is, it runs downward, through the hinge point, driving the guide rail sleeve to run downward along the guide rail, and the pneumatic pick and the tubular drill run downward as they are inserted into the ground. If hard materials such as stones are encountered during the underground insertion, the pneumatic pick is started again, and the drill crushes the stones and continues to move downward until the expected depth, and the drilling hydraulic cylinder stops running. After drilling is completed; start the air compressor (air pump) and close the liquid outlet valve at the same time. High-pressure air enters the cavity of the tubular drill through the air inlet pipeline, the tee, the gas / liquid pipeline, and the arc-shaped tube cavity of the connecting block in turn, and sprays out from the radial holes and the lower end holes of the tubular drill. The high-pressure gas loosens the soil around the drill hole, completing the loosening process; start the fertilizer hydraulic cylinder and open the liquid outlet valve. Its piston rod extends, and the syringe piston moves forward, pushing out the liquid fertilizer in the syringe. The liquid fertilizer enters the cavity of the tubular drill through the tee, the gas / liquid pipeline, and the arc-shaped tube cavity of the connecting block, and sprays out from the radial holes and the lower end holes of the tubular drill. Liquid fertilizer is injected into the root of the tree. Since the soil is loose at this time, it is conducive to the rapid and complete absorption of liquid fertilizer by the roots and the soil near them. Complete drilling a hole in one part → spray air into the hole to loosen the soil → fertilize the hole. Several holes can be drilled around the tree trunk, and the above steps of drilling holes → spraying air into the holes to loosen the soil → applying fertilizer into the holes can be repeated.

[0009] Compared with the prior art, the present invention has the following positive effects: by controlling the stroke of the piston rod of the fertilizer hydraulic cylinder, quantitative fertilization can be implemented, and the tree roots and the soil near them can directly, quickly and completely absorb the applied fertilizer, which is not only beneficial to the growth of trees, but also significantly improves the fertilization effect and realizes precise fertilization; secondly, it greatly reduces labor intensity and improves fertilization efficiency; finally, it can be towed by a motor vehicle to achieve rapid movement.
