Description
FULL-AUTOMATIC FERTILIZER APPLICATOR FOR FRUIT TREE FIELD OF THE INVENTION The present invention belongs to the technical field of agricultural machinery, and particularly relates to a full-automatic fertilizer applicator for a fruit tree. BACKGROUND OF THE INVENTION A liquid fertilizer is a new type of fertilizer in China in recent years; due to the continuous development of agricultural technologies, the liquid fertilizer is not an ordinary foliar fertilizer, but a liquidation of a solid fertilizer, which is in line with the development trend guided by the state, as the liquid fertilizer does not damage roots and seedlings easily, does not cool down after dissolution and dilution, and is easy to be evenly distributed in the soil after an application, unlike the solid fertilizer that causes a high local salinity due to a centralized fertilization, cools down when being diluted and damages the roots and the seedlings; the liquid fertilizer can reduce an infiltration and an evaporation of a water and improve a water use efficiency. The liquid fertilizer realizes a balanced fertilization and the concentrated fertilization, reduces a volatilization and a loss of fertilizer and a loss caused by excess nutrients, and has the advantages of simple fertilization, timely fertilizer supply, easy absorption by crops, and an improved fertilizer utilization. The liquid fertilizer can improve an ecological environment, enhance a microbial activity; promote an absorption of nutrients by the crops and increase a yield of the crops. Therefore, the liquid fertilizer is gradually developed, and the corresponding agricultural machinery is constantly upgraded and updated, so all kinds of liquid fertilizer fertilization machinery are created under this background. In a Patent document CN111295991A, disclosed is a fruit tree fertilization device, which includes a vehicle body, wherein a bottom wall of the vehicle body is provided with a movable cavity that carries a downward opening; a rotating rod is rotationally disposed on a rear side wall of the movable cavity; a ground drilling device is disposed on the rotating rod; the ground drilling device comprises a rotating block fixedly disposed on the rotating rod in the movable cavity; a blade shaft penetrating from a top to a bottom is rotationally disposed on the rotating block; a screw cutter is fixedly disposed on a lower side of the blade shaft; a movable bevel gear is fixedly disposed on an upper side of the rotating block on the blade shaft; a transmission cavity is disposed on a left side of the movable cavity on the vehicle body' a transmission device for controlling a power is disposed in the transmission cavity; a lifting groove with an upward opening is disposed on an upper side of the transmission cavity, and a lifting rod is slidingly disposed in the lifting groove. The device is simple in structure and convenient to operate, and a rotation and a meshing connection of the cutter are controlled by an auxiliary motor, which reduces a space of the device while facilitating a trenching work, while also protecting the device and reducing a damage of the cutter; when the device drives the cutter to rotate, the fertilizer is stirred in a stirring chamber through the worm rotating shaft to for a discharging, and a partition plate is controlled to periodically rotate in a forward-reverse direction to discharge the fertilizer periodically, so that the fertilizer can be fully mixed with the soil; a lifting and a dropping-of the lifting rod is controlled by a strut, while a lifting height can be controlled to adapt to the fruit tree; through a contact with branches and leaves of the fruit tree, a spout contacts with a conduit to spray the fertilizer, which reduces a waste of the fertilizer, and makes more fertilizer contact with the fruit tree. In a patent document CN210694832U, disclosed is a fruit tree cultivation and fertilization device, which includes a feed bin, wherein a hopper is fixedly disposed on one side of a top of the feed bin; a push rod is fixedly disposed on one side of the feed bin; a discharge port is disposed at one side of a bottom end of the feed bin; a discharge pipe is fixedly disposed at a bottom end of the discharge port; a bottom end of the discharge pipe is fixedly connected with top ends of three shunt pipes; a housing is disposed at the other side of the feed bin; a storage battery is fixedly disposed in an interior of the housing through a battery rack, and a vertical plate is fixedly disposed on a bottom of one side of the housing; the utility model is the fruit tree cultivation and fertilization device, and when a worker pushes the push rod in a orchard, wheels are driven to rotate by a gear motor, while the wheels can drive the feed bin to move, which saves a manpower; after the wheels stop rotating, hands of the worker leave the push rod, and the feed bin can be supported by two supporting legs; the fertilizer can be stored in the feed bin, the fertilizer is fed into the feed bin through the hopper, and the soil can be loosened by disposing a loosening rake on one side of the vertical plate.
