Description

Technical Field

[0001] The present invention relates to the technical field of agricultural planting, and specifically relates to an agricultural planting spray fertilization machine. Background Art

[0002] The spray fertilization machine is mainly used to apply fertilizers to crops in the form of spray to improve fertilizer efficiency and crop absorption rate. In agricultural planting, the spray fertilization machine is a key device for realizing precise fertilization, pest control, and increasing crop yield. In the prior art, the nozzles of the device are difficult to be adjusted horizontally, resulting in a small spraying area and uneven fertilizer spraying.

[0003] The patent with the publication number of CN222193125U discloses an agricultural and forestry fertilization spray device, which includes a mobile base, rollers, a water storage tank, a stirring mechanism, a motor, a protective cover, a stirring shaft, spiral stirring blades, a feeding pipe, a pipe cap, a lifting mechanism, a lifting seat, a telescopic rod, a cylinder, a fixed seat, an adjusting mechanism, a fixing plate, a support, a worm, a worm gear, a limiting frame, a rotating shaft, a rotating seat, a transmission mechanism, an installation seat, a first reduction motor, a first support plate, a second reduction motor, a second support plate, a fixing mechanism, a nozzle, a clamping plate, a screw rod, a handwheel, a sliding rod, a water supply mechanism, a water outlet pipe, a water pump, a rotary joint, a hose, a connecting pipe, and a push handle. After adjusting the height of the nozzle to a suitable height, the nozzle can rotate up, down, left, and right along with the rotating seat to adjust the fertilization spraying area, and the installation and disassembly of the nozzle are convenient, which is convenient for maintenance and replacement. Although this patent solves the above problems, there are still problems such as difficult two-dimensional adjustment, low applicability, and uneven spraying when only increasing the spraying area through lifting and rotation. Therefore, an agricultural planting spray fertilization machine is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an agricultural planting spray fertilization machine aiming at the deficiencies in the above-mentioned prior art.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is as follows: An agricultural planting spray fertilization machine includes a moving bracket. A push rod is fixedly connected to the rear side surface of the moving bracket. A fixed frame is fixedly connected to the upper surface of the moving bracket. A liquid storage barrel is fixedly connected to the inner surface of the fixed frame. Above the moving bracket, there is a module fixing device for quickly installing and disassembling spray components. Above the moving bracket, there is a winding device for conveniently winding and unwinding the infusion pipeline. Linear motors are fixedly connected to both sides of the fixed frame. The moving end of the linear motor is fixedly connected to a lifting seat. A rotating block is hinged to the side of the lifting seat away from the linear motor. A sliding arm is fixedly connected to the front side surface of the rotating block. A sliding seat is slidably connected to the outer surface of the sliding arm. An atomizing nozzle is arranged on the side of the sliding seat away from the liquid storage barrel. The liquid storage barrel is in contact with the upper surface of the moving bracket. The linear motor is fixedly connected to the upper surface of the moving bracket. Open the liquid storage barrel and pour liquid fertilizer into the liquid storage barrel. Push the push rod to push the moving bracket and the liquid storage barrel to the crops. At this time, the liquid fertilizer is atomized by the atomizing nozzle and sprayed onto the crops to complete fertilization. During the fertilization process, start the linear motor. The linear motor drives the lifting seat to lift and lower. The lifting seat drives the rotating block to lift and lower. The rotating block drives the sliding arm to lift and lower. The sliding arm drives the sliding seat to lift and lower. The sliding seat drives the atomizing nozzle to lift and lower through the fixed half hoop one and the fixed half hoop two, so as to facilitate fertilization of crops with different heights and growth states during foliar fertilization. When it is necessary to fertilize multiple rows of crops at the same time, rotate the rotating block. The rotating block drives the sliding arm to rotate and expand towards both sides of the fixed frame. At this time, the atomizing nozzle can be moved left and right through the sliding seat, thereby changing the position of the atomizing nozzle.

[0006] Preferably, the module fixing device includes a connecting block. Fixed half-hoop one is hinged to the upper and lower ends of the connecting block, and fixed half-hoop two is hinged to the upper and lower ends of the connecting block. The module fixing device further includes a snap ring. A connecting piece is fixedly connected to the side of the sliding seat close to the liquid storage barrel. A claw is hinged to the circumferential surface of the connecting piece. A diamond-shaped card slot is formed on the side of the sliding arm close to the liquid storage barrel. A connecting plate is fixedly connected to the front side of the sliding seat. The connecting block and the sliding seat are fixedly connected to the side far from the liquid storage barrel. A torsion spring is arranged at the hinge between fixed half-hoop one and the connecting block, and a torsion spring is arranged at the hinge between fixed half-hoop two and the connecting block. A torsion spring is arranged at the hinge between the connecting piece and the claw. The claw and the inner surface of the diamond-shaped card slot are in contact with each other. When it is necessary to replace and clean the atomizing nozzle, rotate and open fixed half-hoop one and fixed half-hoop two, pick up the atomizing nozzle, insert the atomizing nozzle between fixed half-hoop one and fixed half-hoop two, and then release fixed half-hoop one and fixed half-hoop two. The torsion spring drives fixed half-hoop one and fixed half-hoop two to reset and clamp the atomizing nozzle. After inserting the atomizing nozzle between fixed half-hoop one and fixed half-hoop two, the snap ring is stuck above fixed half-hoop one and fixed half-hoop two, so that the atomizing nozzle will not fall off due to the vibration during the movement of the device. When the sliding seat moves to a suitable position, rotate the claw. When the claw aligns with the diamond-shaped card slot, the elasticity of the torsion spring drives the claw to insert into the diamond-shaped card slot to fix the sliding seat with fixed half-hoop one and fixed half-hoop two.

[0007] Preferably, the winding device includes a rotating rod. A winding roller is fixedly connected to the circumferential surface of the rotating rod. An infusion hose is fixedly connected to the front side of the liquid storage barrel. The winding device further includes a rocker. An L-shaped connecting rod is fixedly connected to the lower surface of the connecting plate. The end of the L-shaped connecting rod far from the liquid storage barrel is fixedly connected with a collar. The inner surface of the collar is rotatably connected with a rotating sleeve roller. The rotating rod is rotatably connected to the front side of the fixed frame. The rocker is fixedly connected to the front end of the rotating rod. The infusion hose is in contact with the circumferential surface of the winding roller, and the infusion hose is in contact with the inner surface of the rotating sleeve roller. The infusion hose is fixedly connected to the circumferential surface of the atomizing nozzle. When the atomizing nozzle moves downward, it drives the infusion hose to roll out from the winding roller. When the winding roller is pulled by the infusion hose, it rotates together with the rotating rod, so as to facilitate the extension of the infusion hose. When the atomizing nozzle moves upward, reverse-rotate the rocker. The rocker drives the rotating rod and the winding roller to rotate in the reverse direction to wind up the infusion hose, preventing the infusion hose from being dragged and pulled to cause damage and liquid leakage. When the sliding seat moves up and down, it drives the connecting plate to move up and down. The connecting plate drives the L-shaped connecting rod to move up and down. The L-shaped connecting rod drives the collar to move up and down. The collar drives the rotating sleeve roller to move up and down. The rotating sleeve roller sleeves the infusion hose, and the friction generated between the infusion hose and the rotating sleeve roller when the infusion hose moves up and down makes the rotating sleeve roller rotate.

[0008] Adopting the above technical solution, the present invention can bring the following beneficial effects: 1. The agricultural planting spray fertilization machine drives the atomizing nozzle to rise and fall through the fixed half hoop one and the fixed half hoop two, so as to facilitate fertilization of crops with different heights and growth states during foliar fertilization, enabling the leaves of the crops to be evenly fertilized, improving the fertilization effect. The rotating block drives the sliding arm to rotate and expand to both sides of the fixed frame. At this time, the atomizing nozzle can be moved left and right through the sliding seat, thereby changing the position of the atomizing nozzle to fertilize crops at different distances, expanding the fertilization range and making fertilization more convenient.

[0009] 2. For the agricultural planting spray fertilization machine, when the fixed half hoop one and the fixed half hoop two are rotated and opened, and the atomizing nozzle is picked up, the atomizing nozzle can be quickly disassembled. The torsion spring drives the fixed half hoop one and the fixed half hoop two to reset and clamp the atomizing nozzle, enabling the quick installation of the atomizing nozzle, which improves the convenience of using the device.

[0010] 3. For the agricultural planting spray fertilization machine, the snap ring is stuck above the fixed half hoop one and the fixed half hoop two, so that the atomizing nozzle will not fall off due to the vibration during the movement of the device, improving the installation stability. Furthermore, the stability of the device when spraying fertilizer is improved. The claw is inserted into the diamond-shaped card slot to fix the sliding seat, preventing the sliding seat from shifting when the device moves, further improving the stability of the atomizing nozzle during fertilization and avoiding fertilizer waste.

[0011] 4. For the agricultural planting spray fertilization machine, when the winding roller is pulled by the infusion hose, it rotates together with the rotating rod, facilitating the extension of the infusion hose and improving the applicability of the device. The rotating rod and the winding roller rotate in the opposite direction to wind up the infusion hose, preventing the infusion hose from being dragged and pulled to cause damage and liquid leakage, improving the safety of using the device.

[0012] 5. For the agricultural planting spray fertilization machine, the rotating sleeve roller sleeves the infusion hose to prevent the infusion hose from swaying when moving up and down. Moreover, the friction generated between the infusion hose and the rotating sleeve roller when the infusion hose moves up and down causes the rotating sleeve roller to rotate, preventing the infusion hose from being self-wound due to the kinetic energy influence of the flexible material, resulting in unsmooth infusion.
