UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a complex topography fruit tree fertilizing device to solve the problem that the fertilizer application device cannot accurately control the fertilizer application amount during use, and thus the fertilizer waste and excessive use may occur.

[0006] In order to achieve the above utility model purpose, the utility model adopts the following technical scheme: a complex topography fruit tree fertilizing device, including a fertilizer box, the inner wall front side of the fertilizer box is fixed with an inclined plate, the outer wall front side of the fertilizer box is fixed with a PLC controller, the lower side of the inclined plate is movably provided with a blocking plate, the inner wall front side of the fertilizer box is fixed with an electric push rod, the electric push rod is electrically connected with the PLC controller, one end of the electric push rod telescopic rod is fixedly connected with the front side of the blocking plate, the inside of the fertilizer box is rotatably provided with a weighing box, the inside bottom surface of the weighing box is fixed with a gravity sensor, the gravity sensor is electrically connected with the PLC controller, the outer wall right side of the fertilizer box is fixed with a driving motor, the driving motor is electrically connected with the PLC controller, the output shaft of the driving motor is fixedly connected with the right side of the weighing box, and the inside bottom surface of the fertilizer box is provided with a discharge port.

[0007] Preferably, a connecting rod is fixed to the rear side of the outer wall of the fertilizer box, an installation groove is provided on the top surface of the connecting rod, a movable rod is movably arranged inside the installation groove, a U-shaped frame is fixed to the top of the movable rod, and a shovel is fixed to the bottom surface of the fertilizer box.

[0008] Preferably, the right side of the movable rod has a plurality of threaded grooves, and the right side of the connecting rod has a threaded hole, and a bolt is threadedly connected to the threaded hole, with the threaded end of the bolt connected to the internal thread of the threaded groove.

[0011] Preferably, an observation port is provided on the front side of the fertilizer box, and a PC board is fixed inside the observation port.

[0012] Compared with existing technologies, a fertilization device for fruit trees in complex terrain that adopts the above-mentioned technical solution has the following beneficial effects:

[0013] 1. In use, the staff first fills the fertilizer box with fertilizer, then digs a fertilizer pit around the fruit tree. After moving the fertilizer box to the fertilizer pit, the device is in its initial state. At this time, the baffle plate is pushed by the electric push rod to make tight contact with the rear inner wall of the fertilizer box, effectively sealing the gap between the bottom of the inclined plate and the rear inner wall of the fertilizer box, preventing the fertilizer from falling prematurely. When fertilization is needed, the electric push rod is activated, and its extension rod moves the baffle plate forward. The fertilizer on the inclined plate falls into the weighing box. The gravity sensor in the weighing box monitors the weight of the fertilizer in real time and transmits the data to the PLC controller. When the weight reaches the preset amount of fertilizer, the PLC controller receives the signal and immediately starts the electric push rod to move in the opposite direction, so that the baffle plate re-seals the gap between the bottom of the inclined plate and the rear inner wall of the fertilizer box. At the same time, the drive motor is started, and the output shaft of the drive motor drives the weighing box to rotate, accurately pouring the fertilizer into the fertilizer pit through the discharge port, completing the quantitative fertilization. By using fertilizer bins, inclined plates, baffles, electric push rods, weighing boxes, gravity sensors and drive motors in combination, precise quantitative fertilization of fertilizer is achieved, avoiding fertilizer waste and overuse, improving the degree of automation and reducing the complexity of manual operation.

[0014] Second, during use, workers can hold the U-shaped frame and use a shovel to dig fertilizer pits around the fruit trees, saving the trouble of carrying extra digging tools. Workers can rotate the bolts to unscrew them from the threaded holes, and then move the movable rod up and down to adjust the height of the U-shaped frame. Once adjusted to a suitable height, the bolts are screwed into the corresponding threaded grooves to secure it, making it easy for people of different heights to use, and also easy to disassemble and replace.

[0015] Thirdly, during use, when workers are digging holes with a shovel, they can step on the support pillar, providing a stable support point and improving safety and efficiency during digging. The first and second rubber sleeves enhance comfort and slip resistance when stepping on or holding the shovel. The observation port and PC board allow workers to directly observe the remaining fertilizer level inside the fertilizer bin, facilitating timely replenishment and preventing interruptions or insufficient fertilization.
