Description

TECHNICAL FIELD

[0001] The utility model relates to the field of cucumber cultivation, specifically to a water and fertilizer application device for greenhouse cucumber cultivation. BACKGROUND

[0002] Cucumber is an important vegetable crop and is widely cultivated in greenhouses. Its growth process is extremely strict in water and fertilizer demand, especially at different growth stages, and there is a significant difference in cucumber water and fertilizer demand. Traditional water and fertilizer application methods usually use manual fertilization or simple irrigation systems. These methods are not only inefficient, but also difficult to accurately control the application amount and application time of water and fertilizer, resulting in uneven distribution of water and fertilizer, affecting the growth and yield of cucumbers, and often accompanied by waste of fertilizer.

[0003] Although the existing automatic fertilization system can provide a certain degree of water and fertilizer supply, most of the equipment still has many shortcomings. First, most existing devices only focus on water and fertilizer sprinkling irrigation, ignoring the application of leaf fertilizer, which plays a crucial role in the vigorous growth and fruiting period of cucumbers. It can promote photosynthesis, enhance disease resistance, and improve fruit yield and quality. However, the existing device often cannot meet the precise application needs of water and fertilizer and leaf fertilizer in the same system.

[0004] Secondly, the design of the existing water and fertilizer application device cannot flexibly adapt to the complex environment inside the greenhouse. The space between the plants in the greenhouse is narrow, and the traditional sprinkling irrigation equipment cannot effectively cover each cucumber plant, especially the water and fertilizer supply to the roots and leaves. The problems of inconvenient movement and uneven spraying seriously affect the fertilization effect. UTILITY MODEL CONTENT

[0005] The utility model aims at providing a water and fertilizer application device for greenhouse cucumber cultivation, which combines water and fertilizer sprinkling irrigation and leaf fertilizer spraying mechanism, so that water and fertilizer can be reasonably and accurately applied at each stage from seedling to maturity, and the device has a wide operating range.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a water and fertilizer application device for greenhouse cucumber cultivation, comprising a trailer and a water and fertilizer tank, a leaf fertilizer spraying mechanism, and a water and fertilizer sprinkling irrigation mechanism arranged on the trailer, wherein:

[0007] A mop with a control panel is arranged on the front side of the trailer, and a mounting port is arranged on the rear side of the trailer.

[0008] The water and fertilizer tank is located between the leaf fertilizer spraying mechanism and the water and fertilizer sprinkling irrigation mechanism and is communicated with the leaf fertilizer spraying mechanism and the water and fertilizer sprinkling irrigation mechanism through the water supply member, and the water supply member comprises a pump body and a water inlet pipe and a water outlet pipe communicated with the input and output sides of the pump body, wherein the water inlet pipe and the water outlet pipe are respectively communicated with the water and fertilizer tank and the leaf fertilizer spraying mechanism and the water and fertilizer sprinkling irrigation mechanism.

[0009] The water and fertilizer sprinkling irrigation mechanism is arranged on the front side of the trailer, and comprises a rack, a lead screw, guide rods, a second motor, a lifting support, a V-shaped driving rod, a rotating arm and a sprinkling irrigation frame.

[0010] The leaf fertilizer spraying mechanism is arranged on the rear side of the trailer, and comprises a first motor, a disc, a rotating rod, a first swing rod, a V-shaped connecting rod, a second swing rod, a left spraying frame, a right spraying frame and a spray head.

[0011] Preferably, the leaf fertilizer spraying mechanism can accurately fertilize according to the growth period and fruiting period of cucumbers, promote the healthy growth of plants, improve the photosynthesis efficiency, increase the yield and quality of fruits, and enhance the disease and pest resistance. The water and fertilizer sprinkling irrigation mechanism can reasonably sprinkle according to the water and fertilizer demand of each growth stage of cucumbers, ensure that there is sufficient water and nutrient supply in the seedling stage, growth period, fruiting period and other stages, and avoid the adverse effects of excessive or insufficient water and fertilizer on plant growth.

[0012] Preferably, the lifting support is sleeved on the lead screw and the four guide rods, and the lifting support is hingedly connected with the V-shaped driving rod on both sides.

[0013] Preferably, the bottom end of the rotating arm is hingedly connected to the bottom side of the rack, the top end of the rotating arm is movably connected to the sprinkling irrigation frame, the middle of one side end of the V-shaped driving rod is hingedly connected to the rotating arm, and the other side end of the V-shaped driving rod is hingedly connected to the sprinkling irrigation frame.

[0014] Preferably, a plurality of sprinkling irrigation rows are arranged on the sprinkling irrigation frame, the water outlet pipe is communicated with the sprinkling irrigation rows through a hose, and the sprinkling irrigation frame rotates with the lead screw and performs an extension action. The device is provided with a plurality of spray heads and sprinkling irrigation rows, which ensures uniform spraying during fertilization, avoids uneven or local over-fertilization, and improves the overall effect of fertilization.

[0015] Preferably, the first swing rod and the V-shaped connecting rod are coaxially hingedly connected to the free end of the rotating rod, the middle of the V-shaped connecting rod is movably connected to the bottom side of the trailer frame, and the upper end of the V-shaped connecting rod extends into the mounting port and is hingedly connected to the second swing rod.

[0016] Preferably, the upper ends of the first and second swing arms extend from the mounting ports to both sides of the trailer roof. The end of the first swing arm is hinged to the left spray frame, and the end of the second swing arm is hinged to the right spray frame. Multiple nozzles are installed on both the left and right spray frames. The input side of the nozzles is connected to the water outlet pipe through multiple flexible hoses. The first and second swing arms swing with the rotating rod and drive the left and right spray frames to move to achieve foliar fertilizer swing spraying.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model, through precise control of water and fertilizer application, can meet the water and fertilizer needs of different growth stages in cucumber cultivation. The combination of water and fertilizer sprinkler irrigation and foliar fertilizer spraying mechanisms allows for reasonable and precise application of water and fertilizer at each stage from seedling to maturity, improving fertilization efficiency and reducing fertilizer waste. The design of the water and fertilizer sprinkler irrigation and foliar fertilizer spraying mechanisms allows the equipment to be flexibly adjusted under different operating conditions. For example, the water and fertilizer sprinkler irrigation mechanism can extend with the cooperation of screws, rotating arms, and sprinkler frames, allowing it to reach into the cucumber vines during the trellis-building stage for better water and fertilizer application to the cucumber roots. Meanwhile, the foliar fertilizer spraying mechanism, through the cooperation of swing arms and spraying frames, can achieve synchronous movement of the left and right spraying frames, ensuring complete coverage of the cucumber plants (covering cucumber plants on both sides of the ditch).

[0019] 2. This utility model uses a trailer as a mobile carrier, and the device can quickly move between the furrows and ridges of the greenhouse. Attached Figure Description

[0031] In this embodiment, the foliar fertilizer spraying mechanism 5 and the water and fertilizer spraying mechanism 6 apply fertilizer at different stages of cucumber cultivation. The device can meet the needs of cucumber cultivation throughout the entire process of foliar fertilizer and water and fertilizer application.

[0032] Foliar fertilizer for cucumbers is generally applied during the middle stage of plant growth, especially before the peak growing season and flowering and fruiting period. Specifically, foliar fertilizer application can be divided into the following stages:

[0033] Peak growth period (extension period): When cucumbers enter a rapid growth stage, applying foliar fertilizer can promote robust plant growth, enhance plant photosynthesis, and improve the photosynthetic efficiency of leaves.

[0034] Flowering and fruiting period: Applying foliar fertilizer (especially fertilizer rich in potassium and phosphorus) before the flowering and fruiting period helps increase the yield and quality of the fruit, while also enhancing the plant's resistance to diseases and pests.

[0035] Water and fertilizer application for cucumbers is generally applicable to the entire process of cucumber cultivation and can be divided into the following stages: Spray irrigation and fertilization.

[0036] Seedling stage (from seed germination to seedling stage):

[0037] Sprinkler irrigation requirements: Cucumber seedlings have underdeveloped root systems. The main purpose is to keep the soil moist to promote germination and seedling growth. They do not need too much fertilizer.

[0038] Early growth stage (elongation period):

[0039] Sprinkler irrigation requirements: During this stage, cucumbers enter a rapid growth period and require more water and nutrients to support the growth of the plant's leaves and roots.

[0040] Flowering and fruiting period (from flowering to fruit enlargement):

[0041] Sprinkler irrigation requirements: During the flowering and fruiting period, cucumbers have increased water and fertilizer requirements, especially potassium fertilizer, which can promote fruit enlargement and improve quality.

[0042] Maturity period (fruit ripening period):

[0043] Sprinkler irrigation requirements: Cucumbers have relatively low water and fertilizer requirements during the fruit ripening period, but it is still necessary to maintain an adequate water supply to promote fruit ripening and improve quality.
