Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a fully automatic fruit tree fertilizer applicator. Background Art

[0002] Liquid fertilizer is not easy to hurt the root seedlings, and it does not cool down when dissolved and diluted. It is easy to be evenly distributed in the soil after application. Unlike solid fertilizer, concentrated fertilization forms local high salt, dilution and cooling, which hurts the root seedlings; liquid fertilizer can reduce water infiltration and evaporation, and improve water utilization. Liquid fertilizer realizes balanced fertilization and centralized fertilization, reduces fertilizer volatilization and loss, and the loss caused by excess nutrients. It has the advantages of simple fertilization, timely fertilizer supply, easy absorption by crops, and improved fertilizer utilization. Liquid fertilizer can improve the ecological environment, enhance microbial activity, promote crop absorption of nutrients, and increase crop yields. Therefore, liquid fertilizer has gradually developed, and the corresponding agricultural machinery has been continuously upgraded and replaced, and various liquid fertilizer fertilization machinery should be born.

[0003] Patent document CN111295991A discloses a fruit tree fertilization device, including a body, a bottom wall of the body is provided with an active cavity opening downward, a rotating rod is rotatably mounted on the rear side wall of the active cavity, a drilling device is mounted on the rotating rod, the drilling device includes a rotating block fixedly mounted on the rotating rod in the active cavity, a blade shaft penetrating up and down is rotatably mounted on the rotating block, a spiral cutter is fixedly mounted on the lower side of the blade shaft, a movable bevel gear is fixedly mounted on the blade shaft on the upper side of the rotating block, the body is provided with a transmission cavity on the left side of the active cavity, a transmission device for controlling power is provided in the transmission cavity, a lifting groove opening upward is provided on the upper side of the transmission cavity, a lifting rod is slidably mounted in the lifting groove. The device has a simple structure and is easy to operate. The rotation and meshing connection of the cutter are controlled by an auxiliary motor, which reduces the space of the device and facilitates the digging work, and can also protect the device and reduce the damage of the cutter. While driving the cutter to rotate, the device stirs the fertilizer in the stirring chamber through the worm shaft for easy discharge, and controls the partition to rotate forward and reverse periodically to discharge the fertilizer periodically, so that the fertilizer can be fully mixed with the soil. The lifting and lowering of the lifting rod is controlled by the pressure rod, and the lifting height can be controlled to adapt to the fruit trees. The nozzle and the guide tube are in contact with the branches and leaves of the fruit tree to spray, thereby reducing fertilizer waste and allowing more fertilizer to contact the fruit trees.

[0004] Patent document CN210694832U discloses a fruit tree cultivation and fertilization device, comprising a silo, a hopper is fixedly provided on one side of the top of the silo, a push rod is fixedly provided on one side of the silo, a discharge port is opened on one side of the bottom of the silo, a discharge pipe is fixedly provided at the bottom end of the discharge port, the bottom end of the discharge pipe is fixedly connected to the top ends of the three shunt pipes, a shell is fixedly provided on the other side of the silo, a storage battery is fixedly provided inside the shell through a battery rack, and a vertical plate is fixedly installed on the bottom of one side of the shell. The utility model provides a fruit tree cultivation and fertilization device. When a staff member pushes the push rod in the orchard, the reduction motor drives the rotating wheel to rotate, and the rotating wheel can drive the silo to move, saving manpower. After the rotating wheel stops rotating, the staff member's hands leave the push rod and can support the silo through two supporting legs. The silo can be used to store fertilizer, and the hopper is convenient for feeding into the silo. The soil can be loosened by arranging a loosening rake on one side of the vertical plate.

[0005] Existing machines have the function of applying liquid fertilizer, but the form of fertilization is limited. For large machines, it is not convenient to walk in the orchard, and fertilization is always done on the ground. For some small machines, the degree of automation is not high, and manual assistance is required when fertilizing. When fertilizing fruit trees, it needs to be done many times, which is labor-intensive. Therefore, there are still technical deficiencies such as incomplete functions, narrow working range, low working efficiency, and limited working conditions for fertilization machines specifically used for orchard fruit trees.
