Description

Technical Field

[0001] This utility model relates to the field of agricultural irrigation equipment technology, specifically to an irrigation and fertilization device for corn planting. Background Technology

[0002] Corn is one of my country's main food crops, and its growth requires crucial amounts of water and nutrients.

[0003] Currently, irrigation and fertilization in corn cultivation are mostly carried out separately: irrigation is mostly done by flood irrigation or simple sprinkler irrigation, while fertilization is done by manual spreading or hole application.

[0004] This approach has the following drawbacks:

[0005] It is labor-intensive and inefficient: it requires two separate tasks, consuming a lot of manpower and resources.

[0006] Low water and fertilizer utilization: Flood irrigation and broadcasting can easily cause deep seepage of water and nutrients, surface runoff and volatilization loss, which not only wastes resources, but may also cause soil compaction and environmental pollution.

[0007] Uneven fertilization: Manual fertilization makes it difficult to ensure that each corn plant receives the same amount of nutrients, affecting the balanced growth of the crop.

[0008] Difficulties in mid-to-late stage operation: In the mid-to-late stage of corn growth, the plants are tall and the field is dense, making it difficult for traditional fixed or handheld equipment to enter between rows for precise water and fertilizer application.

[0009] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed an irrigation and fertilization device for corn planting, in order to achieve a more practical value. Utility Model Content

[0013] The adjustable main pipe assembly has L-shaped branch pipes installed on both sides of its top, and the outlet end of the L-shaped branch pipe is connected to an atomizing nozzle.

[0014] A sensing control component is installed on one side of the bottom of the pump casing. The sensing control component includes a hollow arc plate, a rotating shaft, a humidity sensor, and a traction spring. The rotating shaft is installed on the top of the hollow arc plate, and the humidity sensor is installed below the bottom of the hollow arc plate. A traction spring is provided at the horizontal connection end between the hollow arc plate and the pump casing.

[0015] Furthermore, the pumping pipe and the multiple sets of the adjustable main pipe components are interconnected.

[0016] Furthermore, the internal fixed tube and the movable tube are connected by a vertically lifting sleeve.

[0017] Furthermore, a support plate is installed on the outer side of the movable tube, and lifting rods are installed on both sides of the support plate.

[0018] Furthermore, transmission wheel sets are installed on both sides of the bottom of the pump casing and the water-fertilizer mixing tank.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-4 This utility model provides a technical solution: an irrigation and fertilization device for corn planting, including a pump housing 1, an adjustable main pipe assembly 8 and a sensor control assembly 14. A water and fertilizer mixing tank 2 is connected to the horizontal side of the pump housing 1, and a flow control valve 6 is installed on the top side of the water and fertilizer mixing tank 2. The top of the flow control valve 6 is connected to a feeding tank 5, and a water pumping pipe 9 is provided on the other side of the top of the water and fertilizer mixing tank 2.

[0033] Pumps 7 are installed on both sides of the middle part of the pump housing 1, and an adjustable main pipe assembly 8 is installed in the middle part of the pump housing 1. The adjustable main pipe assembly 8 includes an inner fixed pipe 801, a movable pipe 802, a top limiting ring 803 and a sealing ring 804. The top limiting ring 803 is installed on the top of the inner fixed pipe 801, and the movable pipe 802 is sleeved on the upper outer side of the inner fixed pipe 801. The sealing ring 804 is laid on the bottom wall of the outer edge of the top limiting ring 803.

[0034] The adjustable main pipe assembly 8 has L-shaped branch pipes 11 installed on both sides of its top, and the water outlet of the L-shaped branch pipes 11 is connected to an atomizing nozzle 12.

[0035] A sensing control component 14 is installed on one side of the bottom of the pump housing 1. The sensing control component 14 includes a hollow arc plate 1401, a rotating shaft 1402, a humidity sensor 1403, and a traction spring 1404. The rotating shaft 1402 is installed on the top of the hollow arc plate 1401, and the humidity sensor 1403 is installed below the bottom of the hollow arc plate 1401. A traction spring 1404 is provided at the horizontal connection end between the hollow arc plate 1401 and the pump housing 1. The pumping pipe 9 and multiple sets of adjustable main pipe assemblies 8 are interconnected. The inner fixed pipe 801 and the movable pipe 802 are connected by a vertical lifting sleeve. A support plate 13 is installed on the outside of the movable pipe 802, and lifting rods 10 are installed on both sides of the support plate 13. Transmission wheel sets 3 are installed on both sides of the bottom of the pump housing 1 and the water-fertilizer mixing tank 2. A water injection pipe 4 is installed on one side of the outer wall of the water-fertilizer mixing tank 2.

[0036] The water and fertilizer liquid is drawn from the water and fertilizer mixing tank 2 through the water pumping pipe 9, and sprayed from both sides of the device to the outside through the adjustable main pipe assembly 8 connected to the water pumping pipe 9, using the L-shaped branch pipe 11 and atomizing nozzle 12 on the branch. The nozzle is directed towards the root area. With the DC mode, the fertilizer liquid can be delivered directly to the crop roots, minimizing leaf evaporation and deep seepage, thus achieving water and fertilizer conservation.

[0037] Furthermore, by utilizing the sleeve structure of the inner fixed tube 801 and the movable tube 802, the horizontal height of the atomizing nozzle 12 can be adjusted, making it convenient to make corresponding adjustments according to the horizontal height of the crop roots.

[0038] By combining irrigation and fertilization, the water and fertilizer are mixed evenly through a mixer and precisely delivered through a water pump and pipeline, which greatly improves the utilization rate of water and fertilizer, saves resources and manpower. The frame width is specially designed for the spacing between corn rows. The retractable branch irrigation pipe and adjustable nozzle can perfectly adapt to the irrigation and fertilization needs of corn throughout its entire growth process from seedling to maturity, especially solving the pain point of difficult operation in the middle and late stages.

[0039] A hollow arc plate 1401 is axially connected to the rear of the device, and a traction spring 1404 is provided on the outer arc surface of the hollow arc plate 1401 and fixed to the device. When the device moves, it can drive the humidity sensor 1403 at the bottom of the hollow arc plate 1401 to make close contact with the planting area. Based on the soil humidity sensor, the dwell time of the device is controlled, thereby realizing the regulation of irrigation time and timely replenishment of water-deficient areas.

[0040] like Figures 1 to 4 As shown, an irrigation and fertilization device for corn planting includes a mobile device with a pump housing 1 and a water and fertilizer mixing tank 2. Four transmission wheel sets 3 are installed at the bottom of the device. The width of the entire device is set to 60cm to adapt to the common 70-80cm corn row spacing.

[0041] During use, the material supply needs of the device are met through the interfaces on the water injection pipe 4 and the flow control valve 6, and the fertilizer and mixed water are mixed in the water-fertilizer mixing tank 2.

[0042] When moving, the pump 7 inside the pump housing 1 draws water and fertilizer liquid from the water and fertilizer mixing tank 2 through the water suction pipe 9, and then transmits it in sequence through the internal fixed pipe 801, the movable pipe 802 and the L-shaped branch pipe 11, and finally sprays it through the atomizing nozzles 12 on both sides.

[0043] During the movement, the humidity sensor 1403 in the rear sensing control component 14 comes into contact with the planting area. When the humidity sensor 1403 senses that the humidity in the area is low, it controls the moving device to shut down through the controller in the pump housing 1, so that the device stays in the area and performs long-term irrigation to meet the water replenishment needs of the area.

[0044] The humidity sensor 1403 is connected via a hollow arc plate 1401. The design of its arc plate and top shaft allows it to rotate locally when encountering a protrusion in the planting area, avoiding jamming. Furthermore, the traction spring 1404 on the outer arc surface ensures that it fits tightly against the planting area, guaranteeing the accuracy of sensor monitoring.

[0045] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be conceived by those skilled in the art within the technical scope disclosed in this utility model without creative effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope defined in the claims.
