Backpack type electric fertilizer applicator

Abstract

The invention discloses a backpack type electric fertilizer applicator which comprises a charging barrel. The bottom of the charging barrel is provided with a discharging opening. A sliding plate is arranged below the discharging opening to be matched with the discharging opening. The lower part of the charging barrel is connected with a base of which the lower part is connected with a bottom cover. The base is provided with a fan blade in which a shaft sleeve is arranged. The shaft sleeve is provided with a rotary shaft of which the upper end is rotatably matched with the bottom of the charging barrel through a bearing. The lower end of the rotary shaft passes through the base to be connected with a helical tooth tray. A motor fixing seat and a panel are arranged below the base. One side of the motor fixing seat is provided with a motor output shaft which passes through the motor fixing seat to be connected with a small gear. The small gear is engaged with the helical tooth tray. The helical tooth tray drives the rotary shaft. The panel is provided with a power switch and a charging socket. A battery box is arranged below the base, and a battery is arranged in the battery box. The battery supplies power to the motor. The power switch is connected between the battery and the motor. The shaft sleeve is of an excentric shaft sleeve. The sliding plate is provided with a vibrating ring. The excentric shaft sleeve is contacted with the vibrating ring for driving the sliding plate to swing. The pendular sliding plate and the discharging opening are opened and closed, and the bottom of the charging barrel generates micro vibration, so that the chemical fertilizer falls down from the discharging opening.

Description

technical field [0001] The invention relates to a fertilizer applicator, in particular to a backpack type electric fertilizer applicator, which is mainly used for fertilizing and belongs to agricultural machinery. Background technique [0002] When applying chemical fertilizers to rice, wheat, rape, etc., the traditional method uses manual spreading, which has the disadvantages of uneven fertilization, large waste, low efficiency, and great impact on the human body. Therefore, a hand-operated fertilizer applicator was invented, such as Chinese Patent No. CN200710067917 .3. The patent name is "Hand-operated Fertilizer", which drives the gear to rotate by manually shaking the handle, and then the gear drives the wind blade to rotate. The fertilizer falls on the wind blade, and the fertilizer is thrown out by the wind blade to achieve the purpose of fertilization. Its advantages make up for the shortcomings of artificial fertilizer distribution, but because the hand-operated fe...

[0002] When applying chemical fertilizers to rice, wheat, rape, etc., the traditional method uses manual spreading, which has the disadvantages of uneven fertilization, large waste, low efficiency, and great impact on the human body. Therefore, a hand-operated fertilizer applicator was invented, such as Chinese Patent No. CN200710067917 .3. The patent name is "Hand-operated Fertilizer", which drives the gear to rotate by manually shaking the handle, and then the gear drives the wind blade to rotate. The fertilizer falls on the wind blade, and the fertilizer is thrown out by the wind blade to achieve the purpose of fertilization. Its advantages make up for the shortcomings of artificial fertilizer distribution, but because the hand-operated fertilizer applicator holds the fertilizer bucket in one hand, and the other hand keeps shaking the handle, its disadvantages are laborious operation, high labor intensity, and low fertilization efficiency; therefore People have invented electric fertilizers, such as Chinese Patent No. CN200920015757.2, and the patent name is "electric fertilizer". The main shaft of the patented fertilizer adopts a flat semicircular shaft; The turbine on the main shaft is connected to the worm rod at the shaft end of the DC motor; the DC motor, a battery with a voltage of 12V and a power switch constitute a power circuit, which is driven by the motor, and the fertilization mechanism is complicated, so there is a problem that the whole machine is bulky and inconvenient to carry. Disadvantages, the main shaft of the fertilizer applicator is connected by the turbine and the worm, and the cost of the turbine and the worm is high, which increases the manufacturing cost; another example is the Chinese patent No. CN200520029292.8, the patent name is "an electric fertilizer spreader", and its structure includes a frame , the fertilizer box fixed on the frame, the fertilizer taking roller installed in the fertilizer box, the motor is installed on the frame, and one end of the fertilizer taking roller is fixedly connected with the output shaft of the motor. The disadvantage is that it needs to be installed on a walking tractor when using it. It is not suitable for manual carrying, so there is a defect that the operation is limited
