Description

Technical Field

[0001] This utility model relates to the field of Chinese medicinal herb planting technology, specifically a spiral-type organic fertilizer deep application and soil covering integrated machine. Background Technology

[0002] Traditional Chinese medicine emphasizes authentic medicinal materials, which refer to medicinal materials produced in a specific region with specific natural conditions and ecological environment. Some Chinese medicinal materials are plant roots, and fertilization is required during the cultivation process.

[0003] In the traditional cultivation of Chinese medicinal herbs, steps such as ditching, fertilization, irrigation, and covering with soil are mostly completed manually or with simple, single-function equipment, which presents many problems. Manual ditching is not only labor-intensive and inefficient, but also difficult to maintain consistent ditch depth and width, affecting the uniformity of subsequent fertilization and planting. When fertilizing, it is mostly done manually by spreading or shallowly burying, making it difficult for organic fertilizer to reach the root absorption area, easily causing nutrient loss, low fertilizer utilization, and uneven fertilization may also lead to uneven growth of medicinal herbs. Irrigation often lags behind fertilization, requiring separate manual or equipment arrangements after fertilization, which not only increases the process and labor costs, but also prevents water from mixing with fertilizer in time, affecting the root system's nutrient absorption efficiency. Covering with soil mostly relies on manual leveling, making it difficult to ensure uniform coverage thickness, easily resulting in missed or shallow covering, causing fertilizer to be exposed on the surface and rendered ineffective by rainwater or sunlight, and also hindering soil moisture retention.

[0004] In addition, the cultivation of Chinese medicinal herbs has high requirements for soil environment. The decentralized operation of each link in the traditional operation method can easily cause multiple disturbances to the soil structure, destroy the soil aggregate structure, and affect the microenvironment for the growth of medicinal herbs. In view of this, we propose a spiral organic fertilizer deep application and soil covering integrated machine. Utility Model Content

[0043] By setting up the pump body 327, water pipe 328, water inlet funnel 329, and water inlet manual valve 3210, the water supply tank 321 can be controlled and the water supply can be stable, ensuring that the irrigation components 32 can operate continuously and efficiently, avoiding the irrigation rhythm being affected by water supply problems, and ensuring that the moisture level of the ditch meets the standards.

[0044] Sealing rings are provided at the contact points between the water supply tank 321 and the inlet funnel 329 and the water pipe 328. Sealing rings are also provided at the contact points between the water pipe 328 and the outlet end of the pump body 327 and the fixed pipe 322. Sealing rings are also provided at the contact points between the corrugated pipe 326 and the fixed pipe 322 and the outlet pipe 324. Furthermore, a sealing ring is provided at the contact point between the outlet pipe 324 and the nozzle 325.

[0045] By using sealing rings at the contact points of the water supply tank 321, the water inlet funnel 329, and the water pipe 328, each connection point is sealed tightly, preventing water waste caused by leakage and avoiding water seepage affecting other components of the device, thus extending the service life of the equipment.

The position of the fertilization cylinder 332 corresponds to the through hole on the top surface of the working plate 1, and the outer diameter of the fertilization cylinder 332 is smaller than the diameter of the through hole on the top surface of the working plate 1.

[0049] By setting up the fertilizer application components 33 of the irrigation and fertilization mechanism 3, including the connecting rod 331 and the fertilizer application cylinder 332, the fertilizer can be accurately applied to the irrigated ditch. The feeding and unloading are controllable, reducing fertilizer waste and allowing the fertilizer to quickly blend with the moist soil, thereby improving fertilizer absorption efficiency.

[0050] The bottom of the fertilizer cylinder 332 is concave from all sides to the center, and the parts of the fertilizer cylinder 332 that come into contact with the feed funnel 333 and the discharge pipe 335 are all equipped with sealing rings.

The left electric cylinder 23 is located on the top surface of the working plate 1. The piston rod of the left electric cylinder 23 passes through the top surface of the working plate 1 and extends to the bottom of the working plate 1. The lifting block 22 is fixed on the bottom surface of the piston rod of the left electric cylinder 23. Several spiral blades 25 are installed on the outer circumference of the trenching rod 24. The spiral blades 25 are arranged from top to bottom and are installed on the outer wall of the trenching rod 24 in a splicing manner. The trenching rod 24, the unloading pipe 335 and the nozzle 325 are all in the same position and the size is compatible.

[0053] The trenching mechanism 2 features an installation plate 21, a trenching motor 27, a trenching rod 24, etc., which allows for adjustable trenching depth. The spiral blades 25 work in conjunction with the drill bit 26 to quickly and efficiently create trenches with regular shapes, providing a good foundation for subsequent irrigation and fertilization.

[0054] Furthermore, such as Figures 1-2 , Figure 9 As shown, a soil covering mechanism 4 for covering soil is provided near the right end of the bottom surface of the working plate 1. The soil covering mechanism 4 includes a lifting plate 41 located below the working plate 1, two fixed columns 43 fixed on the bottom surface of the lifting plate 41 and symmetrical to each other, two soil covering plates 44 fixed on the bottom surface of the fixed columns 43 on the same side, and an electric push rod 42 with its rod body installed on the top surface of the working plate 1. The piston rod of the electric push rod 42 passes through the top surface of the working plate 1 and extends to the bottom of the working plate 1. The lifting plate 41 is fixed on the bottom surface of the piston rod of the electric push rod 42, and the two soil covering plates 44 are corresponding to the position of the trenching rod 24 and are adapted in size.

[0055] The soil covering mechanism 4 features a lifting plate 41, a fixed column 43, a soil covering plate 44, and an electric push rod 42. This allows for adjustable soil covering height, ensuring tight coverage of ditches, locking fertilizer and water in the soil, reducing loss, and guaranteeing planting results.

[0056] It should be added that the left electric cylinder 23, the trenching motor 27, the right electric cylinder 31, the pump body 327, the solenoid valve 336, and the electric push rod 42 are all electrically connected to the external PLC and the external power supply through wires, and the external PLC is also electrically connected to the external power supply through wires.

[0057] Finally, it should be noted that the components involved in this utility model, such as the left electric cylinder 23, the trenching motor 27, the right electric cylinder 31, the pump body 327, the solenoid valve 336, and the electric push rod 42, are all general standard parts or parts known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the spare parts of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection methods should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0058] In this embodiment, after the external PLC control device is started, it first controls the piston rod of the left electric cylinder 23 to extend and retract according to the preset trenching depth parameters, driving the trenching mechanism 2 to descend precisely to the specified depth. Then, the trenching motor 27 is started, driving the trenching rod 24 to rotate at high speed. The conical drill bit 26 breaks through the surface soil, and the spiral blades 25 transport the soil to both sides to form a regular trench.

[0059] After the trenching operation is completed for a certain distance, the device moves to the top of the ditch under the traction action. The PLC controls the right electric cylinder 31 to adjust the height of the nozzle 325 and the fertilizer component 33 so that they are aligned with the ditch position. Then the pump body 327 is started, and the water in the water supply tank 321 is evenly sprayed out from the nozzle 325 through the transmission path to fully wet the bottom and side walls of the ditch.

[0060] After irrigation, the PLC immediately controls the solenoid valve 336 to open, and the organic fertilizer in the fertilizer cylinder 332 falls quantitatively into the moist ditch through the discharge pipe 335 under the action of gravity, ensuring that the fertilizer and water are initially mixed.

[0061] After fertilization is completed, the device continues to move. The PLC controls the electric push rod 42 to lower the soil covering plate 44 to a suitable height according to the width of the ditch. The two symmetrical soil covering plates 44 push the soil on both sides of the ditch back into the ditch, completing the soil covering and compaction.
