Description

Technical Field

[0001] This invention relates to the field of agricultural technology, and in particular to an integrated irrigation system for mountainous areas. Background Technology

[0002] Integrated water and fertilizer management technology is a new agricultural technology that combines irrigation and fertilization. It utilizes a pressure system or natural terrain gradient to mix soluble solid or liquid fertilizers, tailored to soil nutrient content and crop requirements, with irrigation water. This mixture is then delivered through a controlled pipeline system, ensuring uniform, timely, and quantitative drip irrigation that thoroughly irrigates the crop's root zone. This maintains the soil around the main root system in a loose and appropriately moist condition. Furthermore, it is designed to meet the specific nutrient requirements of different crops, soil conditions, nutrient content, and growth stages, providing water and nutrients directly to the crops in precise quantities and at specific times. Conventional manual spraying of pesticides and fertilizers is labor-intensive, time-consuming, and has low fertilizer utilization and application efficiency.

[0003] Currently, although some mountain irrigation systems exist, most still rely on weather changes. During the rainy and dry seasons, mountain irrigation is often underutilized, or even if it is utilized relatively fully, the wear and tear on the equipment is significant, leading to high irrigation costs.

[0004] To address the aforementioned problems, this invention provides a mountain water and fertilizer integrated irrigation system to solve the issues of previous mountain water and fertilizer irrigation being heavily constrained by weather and having high costs. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated irrigation system for mountainous areas that combines water and fertilizer, thereby reducing irrigation costs and improving irrigation efficiency.

[0006] To achieve the above objectives, the present invention provides the following solution: A mountain irrigation system integrating water and fertilizer includes a water storage tank and a feed mixing tank located at the top of the mountain and interconnected with each other, irrigation tanks arranged in stages on the mountain and connected to the feed mixing tank, and a river channel located at the bottom of the mountain. The river channel is connected to the water storage tank via a water conveyance pipe. A pumping mechanism is installed at the water conveyance pipe in the river channel. The pumping mechanism includes a pump body and a blade drive assembly. The blade drive assembly includes a blade hub, blades evenly arranged circumferentially on the blade hub, and a rotating shaft coaxially arranged with the blade hub. The blades include blades and elastic elements. The blades are mounted on the blade hub via the elastic elements, and the water-facing surface of the blades faces the direction of water flow. One end of the rotating shaft is fixedly connected to the blade hub, and the other end is connected to the power input end of the pump body. The irrigation pools are arranged in a stepped manner from top to bottom on the gentle slope of the mountain. Irrigation holes are opened at the bottom of the irrigation pools and are connected to the irrigation pipeline network. The irrigation pipeline network includes a main pipeline and branch pipelines that are vertically arranged on both sides of the main pipeline and connected to the main pipeline. The main pipeline is laid along the downhill direction of the mountain. It also includes a vertical irrigation system, which includes adjustable-height uprights arranged in an array on a gentle slope and pipes tied to the top of the uprights. Drip irrigation holes are opened at equal intervals on the pipes. The pipes are connected to the irrigation pool. A water pump is installed in the irrigation pool to pump liquid from the irrigation pool to the pipes.

[0007] Preferably, the main pipeline is connected to the irrigation hole, and a valve for discharging material from the irrigation pool is provided on the main pipeline.

[0008] Preferably, a filter layer is provided on the top of the water storage tank, and the filter layer consists of a coarse sand filter layer, a fine sand filter layer and an activated carbon filter layer from top to bottom.

[0009] Preferably, it also includes several rainwater collection channels, which are arranged along the slope of the mountain and whose bottoms are connected to the river channel.

[0010] Preferably, the mixing tank is provided with a stirring device, which includes a base at the bottom of the mixing tank, a rotating shaft on the base, stirring blades on the rotating shaft, and a drive motor outside the mixing tank for driving the rotating shaft to rotate.

[0011] Preferably, the water storage tank and the ingredient mixing tank are connected by a pipeline.

[0012] Preferably, a check valve is installed at the connection between the water storage tank and the batching tank.

[0013] Preferably, the elastic element is a spring.

[0015] Preferably, the system further includes a control system, wherein the pole is equipped with a sensor for monitoring humidity information at different heights, the valve is an electrically controlled valve, and the control system is used to receive the humidity data from the sensor and control the opening and closing of the electrically controlled valve.

[0016] The present invention achieves the following technical effects compared to the prior art: 1. This invention irrigates mountain farmland by constructing a river channel at the base of a mountain and installing a pumping mechanism within the channel. The river channel allows for water storage during the dry season and drainage during the rainy season, providing convenience and speed. Furthermore, because springs are mounted on the blade hubs—specifically, between the blade root and the hub—the blades can bend backward under the impact of the large water flow during floods, preventing damage from excessive water pressure. This blade device design ensures the lifespan of the blade drive assembly within the river channel and prevents damage during floods from affecting subsequent use. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] The purpose of this invention is to provide an integrated irrigation system for mountainous areas that combines water and fertilizer, thereby reducing irrigation costs and improving irrigation efficiency.

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] refer to Figures 1 to 2A mountain irrigation system integrating water and fertilizer includes a water storage tank and a feed mixing tank located at the top of the mountain and interconnected, irrigation tanks arranged in stages on the mountain and connected to the feed mixing tank, and a river channel located at the bottom of the mountain. The river channel is connected to the water storage tank via a water conveyance pipe. A pumping mechanism is installed at the water conveyance pipe in the river channel. The pumping mechanism includes a pump body and a blade drive assembly. The blade drive assembly includes a blade hub, blades evenly arranged circumferentially on the blade hub, and a rotating shaft coaxially arranged with the blade hub. The blades include blades and elastic elements. The blades are mounted on the blade hub via the elastic elements, with the water-facing surface of the blades facing the direction of water flow. One end of the rotating shaft... One end is fixedly connected to the impeller hub, and the other end is connected to the power input end of the pump body. This invention irrigates mountain farmland by constructing a river channel at the bottom of the mountain and setting up a pumping mechanism in the river channel. Due to the construction of the river channel, water is stored in the dry season and drained in the rainy season, which is convenient and fast. In addition, since the spring is installed on the impeller hub, that is, the spring is set between the root of the blade and the impeller hub, when there is a large water flow, the blade can bend backward under the impact of the water flow, avoiding damage to the blade caused by the large water flow. This blade device design can ensure the service life of the blade drive component in the river channel and avoid damage to the blade drive component during floods, which would affect subsequent use.

[0023] refer to Figure 1 The irrigation ponds are arranged in a stepped manner from top to bottom on the gentle slope of the mountain. Irrigation holes are opened at the bottom of the irrigation ponds and are connected to the irrigation pipeline network. The irrigation pipeline network includes a main pipeline and branch pipelines that are vertically arranged on both sides of the main pipeline and connected to the main pipeline. The main pipeline is laid along the downhill direction of the mountain. The stepped arrangement of the irrigation ponds and the laying of the irrigation pipeline network along the mountain's contours allow fertilizer to fully utilize the gravity generated by the mountain's contours to flow freely downwards, thereby ensuring comprehensive and thorough irrigation of the mountain.

[0024] Furthermore, it also includes a vertical irrigation system, which includes adjustable-height uprights arranged in an array on a gentle slope and pipes tied to the uprights. Drip irrigation holes are opened at equal intervals on the pipes. The pipes are connected to the irrigation pool, and a water pump is installed in the irrigation pool to pump liquid from the irrigation pool to the pipes.

[0025] Furthermore, the main pipeline is connected to the irrigation hole, and a valve for discharging materials from the irrigation pool is installed on the main pipeline; once the area irrigated by one of the irrigation pools has been irrigated, the valve can be closed at any time to avoid wasting water and fertilizer in that area.

[0026] Furthermore, a filter layer is installed at the top of the reservoir, consisting of a coarse sand filter layer, a fine sand filter layer, and an activated carbon filter layer from top to bottom. Since the water in the river contains some unabsorbed fertilizer from the mountainside, the composition of the water inevitably changes when it is pumped into the reservoir. This causes deviations in the mixing ratio of water and fertilizer. Therefore, the small amount of fertilizer in the pumped water is filtered out as much as possible to ensure the concentration of the mixed fertilizer.

[0027] Furthermore, it also includes several rainwater collection channels, which are set along the slope of the mountain and connected to the river at the bottom; during the rainy season, the rainwater collection channels set up on the mountain can collect rainwater and enter the river, avoiding water and soil erosion and waste.

[0028] Furthermore, a stirring device is provided in the batching tank. The stirring device includes a base at the bottom of the batching tank, a rotating shaft on the base, stirring blades on the rotating shaft, and a drive motor outside the batching tank for driving the rotating shaft to rotate.

[0029] Furthermore, the water storage tank and the ingredient mixing tank are connected by a pipeline.

[0030] Furthermore, check valves are installed at the connection points between the water storage tank and the batching tank.

[0031] Furthermore, the straight-line distance between adjacent irrigation ponds shall not exceed 20m.

[0032] Furthermore, the elastic element is a spring.

[0033] Furthermore, a coil is also provided on the upright along the direction of the upright, the coil has a through hole, a valve is provided at the through hole, and the top of the coil is connected to the pipeline.

[0034] Furthermore, it also includes a control system. The pole is equipped with a sensor for monitoring humidity information at different heights. The valve is an electrically controlled valve. The control system is used to receive the humidity from the sensor and control the opening and closing of the electrically controlled valve. The control system is based on timing logic or closed-loop control logic based on sensor feedback.

[0035] Any adaptive changes made according to actual needs are within the scope of protection of this invention.

[0036] It should be noted that, for those skilled in the art, it is obvious that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
