Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to a pesticide and fertilizer sprayer for agricultural plant protection. Background Technology

[0002] In agricultural production, crop protection is essential, typically achieved through pesticide spraying to reduce pests and diseases. In areas with favorable conditions, drones are used for spraying, which is more convenient. However, purchasing drones is costly. In economically disadvantaged areas, manual spraying is necessary. When protecting low-growing crops, many workers carry sprayers, bearing the weight of the machine and pesticides while constantly bending over, increasing their workload. Furthermore, sprayers cannot adequately mix different pesticides, leading to phytotoxicity and reduced efficacy. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a reasonably designed and easy-to-use pesticide and fertilizer sprayer for agricultural plant protection. It can allow multiple pesticides to be introduced into the tank in proportion, then mixed, and then sprayed directly without requiring workers to bend over, thus reducing the burden on workers.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: it comprises a box body, a partition, wheels, and a connecting shaft. The box body has an internal partition, the outer peripheral wall of which is fixedly connected to the inner peripheral wall of the box body. Wheels are symmetrically arranged on both the front and rear sides of the box body, and the two symmetrical wheels are connected by a connecting shaft. The front and rear ends of the connecting shaft are respectively screwed onto the outer bottom wall of the box body via axle seats. It further comprises: Storage bins, wherein there are several storage bins, which are equidistantly arranged on one side of the inner body of the bins from front to back, and the opening of the top wall of the storage bins is configured to match the inlet on the top wall of the bins. The feeding mechanism is located on one side inside the box and between the storage box and the partition. The feeding mechanism is connected to the storage box. A stirring mechanism is provided on the side of the partition away from the feeding mechanism; A fixed plate is suspended on the lower side of the box body. The front and rear sides of the upper surface of the fixed plate are connected to connecting rods by hinge seats. The upper end of the connecting rod is connected to a moving block by a hinge seat. The moving block is slidably set in a groove on the bottom wall of the outer side of the box body. Two push screws are symmetrically arranged in the fixed plate. The threads on the push screws are opposite. The push screws are screwed onto the moving blocks on both sides. The two push screws are connected by a synchronous wheel transmission assembly. One end of one of the push screws is connected to a push motor. The push motor is embedded and fixed in the lower side wall of the housing. The spraying mechanism is mounted on a fixed plate, and a pump is fixed on one side wall of the fixed plate. The pump is connected to the housing through a telescopic pipe. The above technical solution involves placing the medicine in several storage bins, then feeding the medicine to the other side of the partition via a feeding mechanism. A stirring mechanism is then activated to agitate the medicine. After agitation, the bin is pushed to the desired fertilization position. A drive motor is then activated, which drives a connected drive screw to rotate. This drive screw, via a synchronous wheel transmission assembly, drives another drive screw to rotate. The two drive screws move the upper end of a connecting rod via a moving block, causing the lower end of the connecting rod to move the fixed plate downwards until the spraying mechanism on the fixed plate reaches the appropriate position. Fertilization is then performed through the spraying mechanism.

[0005] As a further improvement of the present invention, the feeding mechanism includes: The feed pipes are multiple, and they are arranged one-to-one from front to back on one side of the storage box. The feed pipes and the storage box are connected one-to-one by connecting pipes. The spiral conveyor rods are of several kinds and are arranged one-to-one in the feed pipe. The lower end of the spiral conveyor rod is screwed to the lower inner wall of the feed pipe through a bearing, and the upper end of the spiral conveyor rod passes through the top wall of the feed pipe and is screwed to the top wall of the box body through a bearing. The discharge pipe consists of several pipes, each inserted into one side of the outer ring wall of the feed pipe. The other end of the discharge pipe is inclined downward and passes through the partition, and is set in the same plane as the side wall of the partition. The drive motor is embedded and fixed in the top wall of the housing. A drive rod is fixed on the output shaft of the drive motor. The drive rod is connected to the top of several screw conveyor rods through a metering mechanism. With the above technical solution, the medicine in each storage box enters the lower side of the feed pipe through the connecting pipe. The drive motor is started, and the drive motor drives the drive rod to rotate. The drive rod drives the screw conveyor to rotate through the metering mechanism. The screw conveyor drives the medicine to move upward and falls through the discharge pipe to the other side of the box located on the partition.

[0006] As a further improvement of the present invention, the metering mechanism includes: The rotating rods are of several kinds and are equidistant from front to back, screwed into the top wall of the box through bearings. The rotating rods are arranged one-to-one with the screw conveyor rod on one side. The drive rod is connected to the rotating rod through a worm gear pair. The rotating disks are multiple in number and are fixed one-to-one on the top of the rotating rod. Several cylindrical holes are provided on the rotating disks at equal angles. A toggle lever, wherein there are several toggle levers, each of which is inserted into a cylindrical hole, and the protrusion at the top of the toggle lever is set to abut against the upper surface of the rotating disk; A number of actuating gears are provided, and each gear is fitted and fixed to the top of the screw conveyor rod in a corresponding manner. The actuating gears are engaged with the corresponding actuating rods. Through the above technical solution, based on the proportions of various drugs, a suitable number of actuating rods are selected and inserted into the cylindrical holes of the rotating disk. During the rotation of the drive rod, the corresponding rotating rod is driven to rotate through the worm gear pair. The rotating rod drives the rotating disk to rotate, and the rotating disk drives several actuating rods on it to rotate. The actuating rod drives the actuating gear to rotate, and the actuating gear drives the internal spiral conveying rod to rotate. The number of rotations of the spiral conveying rod can be controlled by the number of actuating rods, thereby adjusting the proportion of different drugs entering the box.

[0007] As a further improvement of the present invention, a cover plate is embedded on the top wall of the box body, and several annular grooves are equidistantly arranged on the lower surface of the cover plate. A rolling disk is screwed onto the top wall of the actuating rod through a shaft, and the rolling disk is movably disposed in the annular groove. The above technical solution allows the rotating disk to be positioned by the cover plate, while the top of the actuating rod is set in the annular groove on the bottom wall of the cover plate via a rolling disk, thereby improving the stability of the actuating rod during rotation.

[0008] As a further improvement of the present invention, the stirring mechanism includes: Two reciprocating lead screws are provided, and they are symmetrically arranged on one side of the top wall of the box. The two reciprocating lead screws are connected by a synchronous pulley transmission assembly. One end of one of the reciprocating lead screws is fixed with a stirring motor, which is embedded and fixed in the top wall of the box. The movable plate is suspended on the upper side inside the box, and the two sides of the upper side wall of the movable plate are fixedly connected to the screw nuts on the reciprocating screw. The stirring rods consist of three rods, which are equidistant from left to right and screwed onto the movable plate via bearings. The top of each stirring rod is movably inserted into a rectangular groove on the top wall of the housing. The drive gears consist of three gears, which are fitted and fixed to the top of the stirring rod in a one-to-one correspondence. A rack is meshed on one side of the drive gear, and the rack is fixed to the inner wall of one side of the rectangular groove. The stirring blades are a plurality of blades, which are fixed equally and at equal angles on the outer ring wall of the stirring rod, and the stirring blades on adjacent stirring rods are staggered. With the above technical solution, the stirring motor is started, which drives the reciprocating lead screw connected to it to rotate. The reciprocating lead screw drives another reciprocating lead screw to rotate through the synchronous wheel transmission assembly. The reciprocating lead screw drives the moving plate to move back and forth, and the moving plate drives the stirring rod to move back and forth. During the movement of the stirring rod, the driving gear meshes with the rack, thereby causing the driving gear to rotate. The driving gear drives the stirring rod to rotate. The adjacent stirring rods rotate in opposite directions. The stirring rod drives the stirring blade to rotate, thereby causing the stirring blade to stir the drug.

[0009] As a further improvement of the present invention, the spraying mechanism includes: The diversion pipes are three in number and are arranged from left to right on the lower side of the fixed plate. The middle diversion pipe is embedded and fixed on the lower surface of the fixed plate and is connected to the outlet of the pump. The two middle diversion pipes are connected to the diversion pipes on both sides through telescopic pipes. The sliding blocks are four in number, and they are fixed symmetrically in pairs to the outer ring wall of the two diversion pipes. The inner sliding blocks are slidably set in the groove on the inner top wall of the fixed plate, and the outer sliding blocks are suspended on the outer side of the fixed plate. Two connecting plates are provided, and they are slidably disposed in the grooves on the top wall of the fixed plate.

Atomizing nozzles, wherein there are several atomizing nozzles, and they are equally spaced and arranged in a continuous manner on the lower side of the outer ring wall of the diversion pipe; The above technical solution involves pulling the two diversion pipes from inside the fixed plate to the outside, and then fixing the fixed plate and the connecting plate with bolts, thereby increasing the spraying area. The pump draws the medicine inside the box into the diversion pipe in the middle, and then diverts it to the diversion pipes on both sides through the telescopic pipes on both sides, and finally sprays it onto the plant protection device through the atomizing nozzle.

[0010] As a further improvement of the present invention, a sealing cover is provided on the top wall of the storage box, and the sealing cover passes through the opening on the top wall of the box and is located on the upper side of the box. The above technical solution facilitates the sealing of the storage box, preventing drug spillage during movement.

One side of the guide plate is located below the connecting pipe, and the other side of the guide plate is tilted upward and fixed on the inner side wall of the storage box. The above technical solution facilitates the guidance of drugs in the storage tank, preventing drugs from remaining in the storage tank.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Multiple drugs are poured into the box separately and then fed through the feeding mechanism. At the same time, they can be fed through the quantitative mechanism to achieve the effect of feeding in proportion, which improves the effect of subsequent mixing. 2.
