Description

Technical Field

[0001] This utility model belongs to the field of fertilization technology, specifically relating to an intelligent precision fertilization machine. Background Technology

[0002] In agricultural planting, fertilization is applied during the planting stage to ensure the healthy growth of crops. Fertilization refers to agricultural techniques that involve applying fertilizer to the soil or spraying it on plants to provide the nutrients they need and to maintain and improve soil fertility. The main purpose of fertilization is to increase crop yield, improve crop quality, enrich the soil, and enhance economic benefits. Therefore, rational and scientific fertilization is one of the main means to ensure food security and maintain sustainable agricultural development.

[0003] Fertilizer applicators are needed for fertilization. With the development of technology, intelligent fertilizer applicators have been introduced into farmland. However, existing intelligent fertilizer applicators are designed separately for solid fertilizer and liquid fertilizer. That is to say, solid fertilizer applicators and liquid fertilizer applicators are two different devices and cannot be integrated into one device. In addition, the CNC screen on the intelligent fertilizer applicator lacks an effective protective mechanism. Therefore, we propose an intelligent precision fertilizer applicator. Utility Model Content

[0004] The purpose of this utility model is to provide an intelligent precision fertilizer applicator to solve the problems mentioned in the background art, namely that the existing intelligent fertilizer applicators are designed separately for applying solid fertilizer and liquid fertilizer, that is, the solid fertilizer applicator and the liquid fertilizer applicator are two different devices that cannot be integrated into one device, and the CNC screen on the intelligent fertilizer applicator lacks an effective protective mechanism.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an intelligent precision fertilizer applicator, comprising a frame, with wheels installed at the four corners of the lower surface of the frame; a CNC screen, a solid fertilizer tank, a liquid fertilizer tank, a liquid pump, two mounting bases, and four fixing blocks mounted on the frame; the four fixing blocks are arranged in pairs, with a rotating shaft rotatably mounted between the two fixing blocks in one pair; a protective cover is fixedly mounted on the outer surface of the rotating shaft; a clamping plate is rotatably mounted on the surface of one of the protective covers, and a clamping seat is fixedly mounted on the surface of the other protective cover; the clamping plate is clamped inside the clamping seat; a cover plate is rotatably mounted on the solid fertilizer tank; a cylinder is fixedly mounted on the surface of the solid fertilizer tank; a push plate is fixedly mounted on the end of the piston rod of the cylinder; a push rod is fixedly mounted on the lower surface of the push plate; and the surface of the solid fertilizer tank... A rotating drum is rotatably mounted, and a push rod passes through the rotating drum and works in conjunction with it. A unclogging block is fixedly mounted at the bottom end of the push rod. A material pipe is mounted on the lower surface of the solid fertilizer tank, and the unclogging block works in conjunction with the material pipe. A rotating plate is fixedly mounted on the outer surface of the rotating drum, and several rotating shafts are rotatably mounted on the rotating plate. Several stirring blades are fixedly mounted on the outer surface of the rotating shafts. The inlet end of the liquid pump is connected to the liquid fertilizer tank, and the outlet end of the liquid pump is connected to a T-connector. Both ends of the T-connector are connected to infusion pipes, and the other end of the infusion pipes is connected to a nozzle. A motor is fixedly mounted on the surface of the mounting base, and a threaded rod is rotatably mounted inside the mounting base. The output shaft of the motor is fixedly connected to the threaded rod, and a threaded seat is threadedly mounted on the outer surface of the threaded rod. The nozzle is fixedly mounted on the side of the threaded seat.

[0006] By integrating the solid fertilizer tank and liquid fertilizer tank onto a single frame, both solid and liquid fertilizer can be applied. During solid fertilizer application, the up-and-down movement of the unblocking block prevents blockages and ensures proper feeding. Simultaneously, the mixing blades agitate the fertilizer during this process, allowing for the mixing of various solid fertilizers. For liquid fertilizer application, the nozzle moves up and down via the rotation of the threaded rod, enabling application at different heights. A protective cover isolates and protects the CNC screen; it opens when needed and closes when finished, secured by a locking plate and seat with a locking rod, making operation convenient.

[0007] In the above scheme, it should be noted that the liquid pump, cylinder and motor are all electrically connected to an external power supply.

[0008] In a preferred embodiment, a locking rod is slidably mounted on the locking seat, and a locking hole is provided on the locking plate for the locking rod to be engaged. A spring is fixedly installed between the end of the locking rod and the locking seat.

[0009] The above solution utilizes the spring force in conjunction with the locking rod. When the locking plate is inserted into the locking seat, the locking rod will quickly engage with the locking hole under the pushing action of the spring force, thereby achieving the locking of the locking plate and the locking seat, and thus achieving the locking and locking of the two protective covers. The locking structure is simple and easy to operate.

[0010] In a preferred embodiment, a gear ring is fixedly installed on the inner wall of the solid fertilizer box, and a gear is fixedly installed on the top end of the second rotating shaft. The gear ring and the gear mesh with each other, and the rotating plate is sealed and fitted on the lower surface of the rotating plate.

[0011] Using the above scheme, the gear ring and gear are used in combination. When the rotating plate drives the rotating shaft two to revolve, the rotating shaft two will rotate on its own axis under the meshing action of the gear ring and gear, thereby achieving full mixing and stirring of solid fertilizer.

[0012] In a preferred embodiment, a roller is fixedly mounted on the outer surface of the push rod, and a spiral groove is formed on the inner wall of the rotating cylinder, with the roller rolling against the inner wall of the spiral groove.

[0013] Using the above scheme, the rollers are used in conjunction with the spiral grooves. When the push rod moves up and down, the rollers will roll in the spiral grooves. Therefore, by using the rollers and spiral grooves in combination, the rotating drum can be driven to rotate, which in turn drives the rotating plate to rotate the second rotating shaft, so that the dredging is carried out while stirring.

[0014] In a preferred embodiment, a plurality of guide bars are fixedly installed on the inner wall of the mounting base, and a plurality of guide grooves are provided on the side of the threaded seat, the guide bars and guide grooves being used in conjunction.

[0015] With the above solution, when the threaded rod rotates and drives the threaded seat to move, the threaded seat will slide stably on the surface of the guide bar through the guide groove, and it is not easy for tilting or wobbling to occur.

[0016] In a preferred embodiment, a fixing cover is fixedly installed on the side of the fixing block, and a torsion spring is fixedly installed on the inner wall of the fixing cover and the outer surface of the rotating shaft.

[0017] By adopting the above solution, a fixed cover is used in conjunction with a torsion spring. When the protective cover is in the closed state, the torsion spring is in a deformed state. Therefore, when the protective cover is unlocked, the elastic force of the torsion spring can be used to drive the protective cover to rotate and unfold quickly, improving the ease of operation and use.

[0018] Compared with the prior art, the beneficial effects of this utility model are: This intelligent precision fertilizer applicator integrates solid fertilizer tanks and liquid fertilizer tanks onto a single frame, enabling it to apply both solid and liquid fertilizers. During solid fertilizer application, the up-and-down movement of the unblocking block ensures proper flow, preventing blockages and ensuring timely application. Simultaneously, the mixing blades agitate the fertilizer during this process, allowing for the mixing of various solid fertilizers. For liquid fertilizer application, the nozzle moves up and down via the rotation of the threaded rod, allowing for application at different heights. This intelligent precision fertilizer applicator can isolate and protect the CNC screen by setting a protective cover. When needed, the protective cover can be turned to open, and after use, it can be turned to close. The cover is locked by using a card plate and card seat with a card rod, making it easy to operate.
