Description

Technical Field

[0001] This utility model belongs to the field of fertilization and spraying technology, and more specifically, it relates to an integrated fertilization and spraying machine. Background Technology

[0002] In agricultural production, pesticide application (such as spraying) and fertilizer application (such as fertilizing) are essential steps to effectively control pests and diseases, ensure healthy crop growth, and increase yield. However, traditional methods typically rely on separate, single-function specialized equipment for spraying and fertilizing. This separate equipment configuration means that producers must purchase two independent equipment systems to complete these two basic agricultural activities, significantly increasing the initial purchase cost. More importantly, during the off-season (off-season), these two separate systems cannot be integrated, continuously occupying significant storage space, wasting valuable land resources, and further increasing the overall holding cost of the equipment. Therefore, this paper studies and improves upon the existing structure and its shortcomings to provide an integrated fertilizer and pesticide spraying machine, aiming to achieve greater practical value.

[0025] Example:

[0026] As attached Figure 1 To be continued Figure 6 As shown:

[0027] This utility model provides a fertilizer and pesticide spraying integrated machine, including a mobile frame 1. A storage hopper 2 is fixedly installed on one side of the mobile frame 1. A feed inlet 3 is provided at the top of the storage hopper 2. Main pipes 5 are symmetrically installed on both sides of the top of the storage hopper 2. Multiple sets of branch pipes 6 are equidistantly installed on one side of the main pipe 5. Multiple sets of nozzles 7 are installed on one side of each branch pipe 6. A flexible hose 27 is connected to one end of the main pipe 5, and the other end of the flexible hose 27 is connected to the storage hopper 2. An installation hole is provided at the center of the bottom end of the storage hopper 2. A connecting shaft 8 is rotatably installed inside the installation hole. A stirring blade 9 and a spreading disc 10 are fixedly installed at the upper and lower ends of the connecting shaft 8 on the inner and outer sides of the storage hopper 2, respectively. Multiple sets of discharge ports are provided on the side of the storage hopper 2 near the installation hole. A sealing disc 11 is installed at the bottom end of the storage hopper 2, and the sealing disc 11 is provided with a through-hole corresponding to the discharge port.

[0028] A pump 22 is fixedly installed on one side of the storage hopper 2. The pump 22 is connected to an inlet pipe 23 and an outlet pipe 25 at its two ends. An outlet is provided on one side of the bottom of the storage hopper 2. One end of the inlet pipe 23 is connected to the outlet, and the other end of the outlet is fixedly connected to a filter screen plate 24. The other end of the inlet pipe 23 is connected to one end of a hose 27 through a T-connector. A valve 26 is installed between the hose 27 and the T-connector. The filter screen plate 24 can effectively prevent fertilizer particles from flowing into the inlet pipe 23 during fertilization, improving the ease of use of the device. At the same time, the valve 26 can be opened and closed as needed to adapt to the spraying amount requirements of different crops.

[0029] The storage hopper 2 has two sets of fixed shafts 4 rotatably connected to its top via a fixed base. The main pipe 5 is fixedly connected to each of the fixed shafts 4. A ratchet 15 is installed at one end of each fixed shaft 4. A pawl 14 engages with one side of the ratchet 15. The other end of the pawl 14 is connected to a support frame 13 via a pin. The support frame 13 is fixedly installed at the top of the storage hopper 2. A torsion spring is fitted on the outside of the pin, and the two ends of the torsion spring abut against the support frame 13 and the pawl 14, respectively. A handwheel 16 is fixedly installed at the end of each fixed shaft 4 near the ratchet 15. The handwheel 16 can be rotated to adjust the tilt angle of the main pipe 5 and the branch pipe 6 as needed. After adjusting the outside, it can be automatically locked to adapt to the height requirements of different crops and ensure a stable spraying range.

[0030] The connecting shaft 8 is rotatably connected to the mounting hole via a bearing 20, and a mechanical seal 21 is installed in the mounting hole. A threaded cylinder 17 is provided at the bottom end of the storage hopper 2 near the mounting hole. A through hole is provided at the center of the bottom end of the sealing disc 11. The bottom end of the threaded cylinder 17 passes through the through hole and is connected to a locking nut 18, which enables dynamic adjustment of the sealing disc 11 and prevents leakage during the adjustment process, thereby improving the sealing reliability of the device.

[0031] The multiple sets of material leakage ports are set at equal angles on the same arc, and the center of the arc coincides with the central axis of the mounting hole. The material leakage ports are distributed at equal angles with the mounting hole as the center, ensuring that when the spreading disc 10 rotates, the fertilizer drop point of each material leakage port is evenly distributed in the circumference. Combined with the centrifugal force of the spreading disc 10, a uniform ring spreading area is formed, avoiding local over- or under-fertilization.

[0032] The sealing disc 11 is provided with a limiting pin 28 at its top, and the storage hopper 2 is provided with an arc-shaped limiting groove at its top. The limiting pin 28 is slidably installed in the arc-shaped limiting groove. The center of the arc-shaped limiting groove coincides with the central axis of the mounting hole, which facilitates the restriction of the rotation angle of the sealing disc 11, prevents it from rotating excessively, and realizes the quantitative adjustment of the fertilizer application amount.

[0033] The top of the sealing disc 11 is fixedly bonded with a sealing gasket 12, which fills the gap between the sealing disc 11 and the bottom of the storage hopper 2. Even when the equipment is bumpy or tilted, it can effectively prevent solid fertilizer powder or liquid medicine from leaking, avoid polluting the environment or corroding equipment parts, and improve safety.

[0034] The mobile frame 1 is equipped with multiple sets of batteries 29 and a controller. A motor 30 is fixedly installed on one side of the mobile frame 1 via a connecting frame, and the output end of the motor 30 is connected to the bottom end of the spreading disc 10. A traction frame 19 is fixedly installed on one side of the mobile frame 1. The bottom of the mobile frame 1 is symmetrically equipped with moving wheels. The batteries 29 can power the motor 30, thereby driving the spreading disc 10 to rotate, so that field operations can be carried out without an external power source.

[0035] The working principle of this embodiment:

[0036] When in use, the integrated fertilizer and pesticide spraying machine is connected to a towing vehicle via the towing frame 19, allowing for flexible movement in the field to adapt to the operational needs of different plots. When fertilization is required, the operator feeds granular fertilizer into the storage hopper 2 through the feed inlet 3. Then, according to the fertilization needs, the operator rotates the locking nut 18 and the sealing disc 11 to adjust the alignment between the discharge port of the storage hopper 2 and the sealing disc 11, thereby controlling the fertilizer's descent. After the sealing disc 11 is adjusted, the locking nut 18 is tightened to lock the position of the sealing disc 11. The fertilizer then flows from the arc-shaped groove at the bottom of the storage hopper 2 onto the spreading disc 10. The motor 30 is then started, and its output drives the connecting shaft. Rotating shaft 8 drives the spreading disc 10 to rotate at high speed, spreading fertilizer evenly onto the farmland. When spraying is required, first rotate the sealing disc 11 to seal the leakage port at the bottom of the storage hopper 2. Then, inject the liquid into the storage hopper 2 and start the pump 22. The pump 22 then draws the liquid from the storage hopper 2 through the inlet pipe 23 and delivers it to the valve 26 and hose 27 through the outlet pipe 25. The operator can adjust the valve 26 to control the flow rate of the liquid according to the spraying needs. At the same time, by rotating the handwheel 16, the angle of the main pipe 5 can be adjusted with the cooperation of the ratchet 15 and the pawl 14, so that the nozzle 7 can be aimed at the crops for even spraying.

Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
