Description

Technical Field

[0001] This utility model relates to the field of saline-alkali land planting technology, and in particular to a circulating drip irrigation device suitable for saline-alkali land planting. Background Technology

[0002] Saline-alkali soil is a general term for saline soil and alkaline soil. Saline soil mainly refers to saline soil with high chloride or sulfate content, which is alkaline but the pH value is not necessarily high. Alkaline soil refers to soil containing carbonate or diphosphate, which has a higher pH value and is alkaline. Saline-alkali soil has low organic matter content, low soil fertility, poor physical and chemical properties, and contains more harmful anions and cations to crops, making it difficult for crops to grow. The fertilization principle for saline-alkali soil is to mainly apply organic fertilizers and high-efficiency compound fertilizers, and control the use of low-concentration chemical fertilizers. Organic fertilizers contain a large amount of organic matter, which plays a buffering role against harmful anions and cations in the soil and is conducive to root development and seedling promotion. High-concentration compound fertilizers have fewer ineffective components and less residue, but the amount of chemical fertilizers should not be too much each time to avoid aggravating secondary salinization of the soil. After applying chemical fertilizers, irrigation should be combined to reduce the soil solution concentration.

[0003] According to the announcement number (CN222090427U), a circulating drip irrigation device for planting in saline-alkali land includes a drip irrigation box. The upper end of the drip irrigation box has a placement groove, and the lower front side of the drip irrigation box has an opening groove. The opening groove is connected to two symmetrically arranged sliding grooves on the drip irrigation box. The device includes a drip irrigation box, a placement groove, sliding grooves, a filter screen assembly, a sealing and clamping assembly, a support ring, a planting assembly, and an opening groove. This utility model enables convenient removal of the filter screen body after long-term use, thereby improving filtration efficiency.

[0004] While the above solution allows for easy removal of the filter body using a sealed clamping component, it still cannot prevent soil from seeping into the filter body during actual drip irrigation operations. This can lead to severe blockage of the filter body during use, reducing the water delivery efficiency of the drip irrigation system and affecting the uniformity of water and fertilizer delivery. Furthermore, due to the limitations of the drip irrigation operation process, the filter body can only be removed and cleaned after the entire drip irrigation cycle is completely finished. It is impossible to perform timely maintenance during the operation, which can easily cause drip irrigation interruption due to filter blockage, affecting the normal irrigation needs of crops in saline-alkali land. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a circulating drip irrigation device suitable for planting in saline-alkali land, thereby solving the aforementioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A circulating drip irrigation device suitable for planting in saline-alkali land includes a housing, which contains a water tank, a collection tank, and a planting box.

[0009] Preferably, a guide rod is fixedly connected between one side of the base plate and one side of the inner wall of the box. The guide rod and the outer side of the first lead screw are threaded with the same diversion box. The other end of the delivery pipe is fixedly connected to one side of the diversion box and communicates with the diversion box. Multiple nozzles are provided on the bottom side of the diversion box, and all the nozzles face the planting box.

[0010] Preferably, the mobile cleaning assembly includes a circular hole on one side of the housing, a second lead screw installed in the circular hole, one end of the second lead screw being rotatably connected to the inner wall of one side of the housing, a guide post fixedly installed inside the housing, and the same sliding plate threaded onto the outer side of the guide post and the second lead screw.

[0011] Preferably, a second synchronous pulley and a first synchronous pulley are fixedly sleeved on the outer side of the second lead screw and the outer side of the first lead screw, respectively, and the second synchronous pulley and the first synchronous pulley share the same synchronous belt.

[0012] Preferably, a baffle is fixedly installed inside the housing, and the baffle is located above the second lead screw.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. Through the cooperation of a motor, a first lead screw, a first synchronous pulley, a synchronous belt, a second synchronous pulley, a second lead screw, a sliding plate, and a brush, when the motor drives the first lead screw to rotate, the second lead screw can be driven to rotate synchronously through the synchronous pulley and synchronous belt, causing the sliding plate to move back and forth along the guide post, driving the brush to continuously clean impurities on the surface of the filter plate. This structure can prevent soil and other impurities from accumulating on the surface and inside of the filter plate in real time, avoiding filter plate blockage, ensuring stable water delivery efficiency of the drip irrigation system, and ensuring uniform water and fertilizer delivery, thus solving the problem of filter screen blockage affecting irrigation effect in the background technology.

By connecting the filter plate to the slot on one side of the collection box, and combining the circulation structure of the circulation pump, water pumping pipe and water delivery pipe, the filter plate can be easily pulled out for cleaning or replacement without waiting for the entire drip irrigation operation to end. At the same time, the circulation pump can return the filtered water to the water tank for recycling, ensuring the normal irrigation needs of crops in saline-alkali land, improving water resource utilization, and adapting to planting scenarios where freshwater resources are scarce in saline-alkali land.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0018] Example: Refer to Figure 1-4A circulating drip irrigation device suitable for planting in saline-alkali land includes a housing 1, inside which are a water tank 2, a collection tank 3, and a planting box 22. The bottom of the planting box 22 has multiple drainage holes. A water pumping component and a mobile water spraying component are respectively installed on the bottom side of the water tank 2. A slot is provided on one side of the collection tank 3, into which a filter plate 4 is inserted. A mobile cleaning component is installed above the filter plate 4. A transmission component is provided between the mobile cleaning component and the mobile water spraying component. A circulating pump 23 is fixedly installed on one side of the housing 1, and a [missing information - likely a device name or component] is fixedly connected to the bottom side of the circulating pump 23. A water suction pipe 24 extends to the collection tank 3 at one end. A water delivery pipe 25 is fixedly connected to the top side of the circulation pump 23, and the other end of the water delivery pipe 25 extends to the water tank 2. The movable cleaning assembly includes a round hole on one side of the housing 1, in which a second lead screw 16 is installed. One end of the second lead screw 16 is rotatably connected to the inner wall of one side of the housing 1. A guide post 17 is fixedly installed inside the housing 1. The guide post 17 and the outer side of the second lead screw 16 are threaded with the same sliding plate 18. The sliding plate 18 is T-shaped, and multiple brushes are fixedly connected to the bottom side of the sliding plate 18. The other end of each brush is attached to the filter plate 4. A second synchronous pulley 19 and a first synchronous pulley 15 are fixedly sleeved on the outer side of the second lead screw 16 and the outer side of the first lead screw 8, respectively. The second synchronous pulley 19 and the first synchronous pulley 15 share the same synchronous belt 20. Through the first synchronous pulley 15 fixedly sleeved on the outer side of the first lead screw 8, and because the first synchronous pulley 15 and the second synchronous pulley 19 share the same synchronous belt 20, under the meshing transmission of the synchronous belt 20, the second synchronous pulley 19 synchronously drives the second lead screw 16 connected to it to rotate, thereby... The sliding plate 18, which is threaded onto the second lead screw 16, drives multiple brushes fixedly connected to the bottom side to reciprocate along the guide post 17 to clean the impurities on the surface of the filter plate 4. By cleaning the impurities, excessive accumulation of impurities can be avoided, which would affect the filtration effect of the filter plate 4. With the circulation pump 23 installed, the water filtered by the filter plate 4 will be stored in the collection tank 3. At this time, the water pump 12 will be started to drive the water pumping pipe 24 to draw water from the collection tank 3. Then, the water will be transported to the water tank 2 through the water delivery pipe 25 to realize the recycling of water resources.

[0019] Specifically, the water pumping assembly includes a water pump 12 fixedly installed on the bottom side of the water tank 2, an extraction pipe 13 fixedly connected to the top side of the water pump 12, the other end of the extraction pipe 13 extending into the water tank 2, and a delivery pipe 14 fixedly connected to the bottom side of the water pump 12. By setting up the water pump 12, when it is necessary to wet the soil in the planting box 22, the water pump 12 is started to drive the extraction pipe 13 to draw water from the water tank 2, and then the water is delivered to the distribution box 10 through the delivery pipe 14. Then, multiple nozzles 11 set on the bottom side of the distribution box 10 spray the water onto the soil in the planting box 22. In addition, the water spraying can be achieved by moving the water spraying assembly during the water spraying process, so that the soil can be better and more evenly wetted.

[0020] Specifically, the mobile sprinkler assembly includes a base plate 5 fixedly connected to the bottom side of the water tank 2, a fixing frame 6 fixedly installed on one side of the tank body 1, a motor 7 fixedly installed on one side of the fixing frame 6, the output end of the motor 7 rotatably passing through the fixing frame 6 and the tank body 1 and fixedly connected to a first lead screw 8, the other end of the first lead screw 8 being rotatably connected to one side of the base plate 5, and a guide rod 9 fixedly connected between one side of the base plate 5 and one side of the inner wall of the tank body 1, with the same diversion box 1 threaded onto the outer sides of the guide rod 9 and the first lead screw 8. 0. The other end of the delivery pipe 14 is fixedly connected to one side of the diversion box 10 and communicates with the diversion box 10. Multiple nozzles 11 are provided on the bottom side of the diversion box 10. All nozzles 11 face the planting box 22. A motor 7 is provided. During the spraying of water by the multiple nozzles 11, the motor 7 drives the first lead screw 8 to rotate, so that the diversion box 10, which is externally threaded to the first lead screw 8, moves back and forth along the guide rod 9, so that the water sprayed by the nozzles 11 can evenly wet every part of the soil in the planting box 22.

[0021] Specifically, a baffle 21 is fixedly installed inside the box 1. The baffle 21 is located above the second lead screw 16. By setting the baffle 21, the baffle 21 can block the water dripping from the planting box 22, thereby preventing water containing impurities from adhering to the second lead screw 16 and affecting the sliding of the slide plate 18.

[0022] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be any conventional known device, such as a computer, that can control the operation of the electrical components mentioned in the article.

[0023] In use: When it is necessary to wet the soil in the planting box 22, the water pump 12 is started. After the water pump 12 starts running, it draws water from the water tank 2 through the extraction pipe 13. The water is then transported to the distribution box 10 through the delivery pipe 14. Multiple nozzles 11 arranged on the bottom side of the distribution box 10 spray the water evenly onto the soil in the planting box 22. During the water spraying process, the motor 7 is started simultaneously. The motor 7 drives the first lead screw 8 to rotate, causing the distribution box 10, which is threadedly connected to the first lead screw 8, to move back and forth along the guide rod 9. This allows the water sprayed from the nozzles 11 to fully and evenly wet every part of the soil in the planting box 22. Excess water generated during irrigation flows into the collection box 3 through multiple drainage holes on the bottom side of the planting box 22. The filter plate 4 in the collection box 3 can immediately intercept impurities in the water, preventing impurities from entering the collection box 3 and preventing malfunctions such as blockage or overload during the operation of the subsequent circulation pump 23. The first synchronous pulley fixedly connected to the outside of the first lead screw 8... 15. The first synchronous pulley 15 meshes with the second synchronous pulley 19 through the synchronous belt 20, driving the second synchronous pulley 19 and the second lead screw 16 connected thereto to rotate synchronously. When the second lead screw 16 rotates, the sliding plate 18 with its outer thread sleeve will reciprocate along the guide post 17, driving multiple brushes fixed on the bottom side of the sliding plate 18 to clean the impurities accumulated on the surface of the filter plate 4, effectively avoiding excessive accumulation of impurities that would reduce the filtration efficiency of the filter plate 4. The water source filtered by the filter plate 4 is retained in the collection tank 3. At this time, the circulation pump 23 is started. The circulation pump 23 draws the purified water source in the collection tank 3 through the water pumping pipe 24, and then sends it back to the water tank 2 through the water delivery pipe 25, realizing the recycling of water resources. After the entire drip irrigation operation is completed, the operator only needs to open the device box door to pull the filter plate 4 out from the preset slot in the collection tank 3, and then thoroughly clean the filter plate 4, or directly replace it with a new filter plate 4 to ensure the stable operation of the subsequent device.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
