Description

Technical Field

[0001] This utility model belongs to the field of fruit tree seedling irrigation, specifically relating to an integrated water and fertilizer irrigation device for fruit tree seedlings. Background Technology

[0002] In the current technology for watering and fertilizing fruit trees, the commonly used methods are traditional manual application of fertilizer and water. This method results in uneven fertilization and watering, and some areas where fertilizer is concentrated may experience seedling burn. This can also affect the growth and yield of fruit trees, and even indirectly affect the fruit trees' immunity and resistance to diseases and pests.

[0003] The integrated water and fertilizer irrigation equipment for fruit tree seedlings is a new agricultural technology that integrates irrigation and fertilization. It consists of a water source, a main control unit, a pipeline system, a fertilization system, and irrigation equipment, offering advantages such as water saving, fertilizer saving, labor saving, land saving, and increased yield. Patent document CN222621629U discloses an integrated water and fertilizer irrigation device for four-season citrus trees that facilitates mixing. By installing a stirring rod inside the mixing tank, it is convenient to thoroughly mix water and fertilizer. However, this device does not consider cleaning the tank walls after fertilization. Because insoluble components and impurities in the fertilizer easily deposit on the tank walls, forming hard scale, which gradually detaches and clogs filters and drip irrigation nozzles, leading to uneven irrigation. Furthermore, residues can interfere with the uniformity of the newly mixed fertilizer solution. The organic matter and humid environment remaining on the tank walls promote the growth of algae, fungi, or harmful bacteria (such as Fusarium), producing biofilms and polluting the irrigation water. While the bottom of the mixing tank can be cleaned with a powerful flush, the limited space at the tank opening makes it difficult to effectively clean the side walls.

[0004] Therefore, how to provide an integrated water and fertilizer irrigation device for fruit tree seedling cultivation that can effectively clean the side wall of the mixing tank has become a problem that needs to be considered by those skilled in the art. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a guide column, mounting bracket, and scraper on the stirring mechanism. This allows for effective cleaning of the side wall of the mixing tank while stirring water, and also facilitates the cleaning and replacement of the scraper, preventing impurities from remaining on the scraper.

[0006] To achieve the above objectives, the present invention specifically discloses the following solution:

[0007] An integrated water and fertilizer irrigation device for fruit tree seedlings includes a mixing tank, a Venturi fertilizer applicator, a centrifugal pump, a filtration mechanism, and irrigation pipelines. The centrifugal pump is connected to a water source via an inlet pipe. The centrifugal pump, Venturi fertilizer applicator, and irrigation pipelines are installed in series. The Venturi fertilizer applicator is connected to the mixing tank via a fertilizer suction pipe. A drive motor is installed at the top of the mixing tank.

[0008] Furthermore, the guide post has a first limiting protrusion at its front end and a second limiting protrusion at its top end. T-shaped grooves penetrating the second limiting protrusion are provided on both sides of the top end of the guide post. A strong spring and a mounting bracket are slidably passed through the guide post between the first limiting protrusion and the second limiting protrusion. One end of the strong spring abuts against the first limiting protrusion, and the other end of the strong spring abuts against the mounting bracket.

[0009] Furthermore, the clamp includes a first clamping plate, a second clamping plate, and a cylindrical pin. The first clamping plate and the second clamping plate are arranged in an X-shape and hinged by the cylindrical pin. The cylindrical pin is fixed in the mounting frame. A return spring is arranged around the surface of the cylindrical pin to keep the clamping ends of the first clamping plate and the second clamping plate in a clamped state. A strip-shaped drive plate is hinged to the end of each of the first clamping plate and the second clamping plate. The end of the strip-shaped drive plate is slidably limited in a T-shaped groove at the top of the guide post. A rotating pin is provided at the end of the strip-shaped drive plate.

[0010] Furthermore, the filtration mechanism includes a primary filter and a secondary filter, with the primary filter installed at the end of the inlet pipe and the secondary filter installed on the main pipe.

[0011] Furthermore, the irrigation pipeline includes a main pipeline and branch pipelines. The main pipeline is connected to the outlet pipe of the Venturi fertilizer applicator, and the branch pipelines are connected in parallel to the main pipeline.

[0012] Furthermore, it also includes a water distribution pipe, which is installed on the main pipeline via a tee. The water distribution pipe is equipped with a ball valve, and the outlet end of the water distribution pipe extends into the mixing tank.

[0013] Furthermore, a drain outlet is provided at the bottom of the mixing tank, and a drain valve is installed at the drain outlet.

[0014] Furthermore, a filter screen is provided at one end of the fertilizer suction tube that extends into the mixing tank.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This utility model has a simple structure and low cost, making it convenient for farmers to achieve integrated water and fertilizer irrigation for fruit tree seedlings.

Detailed Implementation

[0022] 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.

[0023] Example 1

[0024] like Figure 1-4As shown in the figure, this embodiment discloses an integrated water and fertilizer irrigation device for fruit tree seedlings, including a mixing tank 1, a Venturi fertilizer applicator 2, a centrifugal pump 3, a filtration mechanism, and an irrigation pipeline. The centrifugal pump 3 is connected to a water source through an inlet pipe. The centrifugal pump 3, the Venturi fertilizer applicator 2, and the irrigation pipeline are installed in series. In this utility model, the irrigation pipeline includes a main pipeline 4 and branch pipelines 5. The main pipeline 4 is connected to the outlet pipe of the Venturi fertilizer applicator 2, and the branch pipelines 5 are connected in parallel to the main pipeline 4. The branch pipelines 5 are equipped with pressure compensation drippers 6 according to the spacing of the seedlings. The filtration mechanism includes a primary filter 7 and a secondary filter 8. The primary filter 7 is installed at the end of the inlet pipe for filtering the water source, and the secondary filter 8 is installed on the main pipeline 4 for filtering the water-fertilizer mixture to prevent clogging of the pressure compensation drippers 6.

[0025] The Venturi fertilizer applicator 2 includes a main pipe and an extended branch pipe, which are connected in parallel to the main pipe. The main pipe is equipped with a flow rate regulating valve 9, and the branch pipe is equipped with a fertilizer suction pipe 10. The fertilizer suction pipe 10 extends into the mixing tank 1 and is used to suck the mixed fertilizer into the Venturi fertilizer applicator 2. As a preferred embodiment of this utility model, a filter screen 11 is provided at one end of the fertilizer suction pipe 10 that extends into the mixing tank 1 to prevent undissolved fertilizer from entering the Venturi fertilizer applicator 2.

[0026] In this invention, a drive motor 12 is installed at the top of the mixing tank 1. A stirring mechanism connected to the drive shaft of the drive motor is installed inside the mixing tank 1. The stirring mechanism includes a stirring shaft 13, a guide column 14, a mounting frame 15, and a scraper 16. The guide column 14 is vertically installed at the top and bottom of the stirring shaft 13. The mounting frame 15 is slidably mounted on the guide column 14. A handle 20 is provided at the front end of the mounting frame 15, and clamps are provided at both the upper and lower ends of the mounting frame 15. The scraper 16 is mounted on the mounting frame 15 via the clamps. In this embodiment, a brush is provided at the front end of the scraper 16. A drain outlet with a drain valve 26 is installed at the bottom of the mixing tank 1.

[0027] To facilitate the disassembly of the scraper 16, in this embodiment, the front end of the guide post 14 is provided with a first limiting protrusion 17, and the top end of the guide post 14 is provided with a second limiting protrusion 18. T-shaped sliding grooves penetrating the second limiting protrusion 18 are provided on both sides of the top end of the guide post 14. A strong spring 19 and a mounting bracket 15 are slidably passed through the guide post between the first limiting protrusion 17 and the second limiting protrusion 18. One end of the strong spring 19 abuts against the first limiting protrusion 17, and the other end of the strong spring 19 abuts against the mounting bracket 15, so that the mounting bracket 15 abuts against the second limiting protrusion 18.

[0028] The clamp in this embodiment includes a first clamping plate 21, a second clamping plate 22, and a cylindrical pin 23. The first clamping plate 21 and the second clamping plate 22 are arranged in an X-shape and hinged together by the cylindrical pin 23. The cylindrical pin 23 is fixed on the mounting bracket 15. A return spring is surrounded by the cylindrical pin 23 to keep the clamping ends of the first clamping plate 21 and the second clamping plate 22 in a clamped state. The ends of the first clamping plate 21 and the second clamping plate 22 are both hinged to a strip-shaped drive plate 24. The end of the strip-shaped drive plate 24 is slidably limited in the T-shaped groove at the top of the guide post 14. In this embodiment, a rotating pin is provided on one side of the strip-shaped drive plate 24 located in the T-shaped groove, which enables the end of the strip-shaped drive plate 24 to rotate in the T-shaped groove.

[0029] The powerful spring 19 in this invention ensures that the scraper can be firmly pressed against the side wall of the mixing tank 1. When the scraper 16 needs to be replaced, the operator only needs to pull the handle 20 towards the center of the mixing tank, so that the mounting bracket 15 slides backward on the guide post 14. The scraper 16 no longer presses against the side wall of the mixing tank 1. After the strip drive plate 24 presses against the bottom of the T-shaped chute, the operator continues to pull the handle 20. The strip drive plate 24 drives the end of the clamp to rotate towards the guide post 14, causing the clamp to open. When the operator removes the old scraper and puts the new scraper 16 into the clamp, the operator releases the handle 20. The mounting bracket 15 moves forward under the push of the powerful spring 19, so that the strip drive plate 24 is disengaged from the bottom of the chute. At this time, the first clamp 21 and the second clamp 22 clamp the new scraper 16 under the drive of the return spring, thus completing the replacement of the scraper 16.

[0030] As a preferred embodiment of the present invention, the present invention also includes a water distribution pipe 25, which is installed on the main pipeline 4 via a tee. A ball valve is provided on the water distribution pipe 25, and the outlet end of the water distribution pipe 25 extends into the mixing tank 1. The function of the water distribution pipe 25 is to provide water for the mixing tank 1 when dissolving fertilizer, and to play a certain role in relieving pressure when the pressure in the main pipeline 4 is too high. At the same time, it is used for cleaning the mixing tank 1 after irrigation.

[0031] When using this utility model, first inject a certain amount of clean water into the mixing tank 1 using the water distribution pipe 25, then add fertilizer in the same proportion, turn on the drive motor 12 to stir, and turn off the motor after stirring. Then, put the fertilizer suction pipe of the Venturi fertilizer applicator 2 into the mixing tank 1, turn on the centrifugal pump 3, and turn on the flow rate regulating valve of the Venturi fertilizer applicator 2 to realize integrated water and fertilizer irrigation for fruit tree seedlings.

[0032] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
