Description

Technical Field

[0001] This application relates to the field of sandy land fertilization technology, specifically a sandy land deep fertilization device. Background Technology

[0002] Sandy land refers to a type of land whose surface cover is mainly sand. This type of land has relatively large gaps between sand grains, resulting in good aeration, but poor water and fertilizer retention capacity. Therefore, fertilization equipment with deep fertilization capabilities is needed to fertilize this type of land.

[0003] To provide initial nutrition for seed germination and to establish a root absorption zone, fertilization devices are usually used to fertilize the sandy soil before planting the seeds. This improves the soil structure, reduces nutrient loss, and increases water and fertilizer retention capacity.

[0004] Soil structure and moisture content vary in different regions, so the required fertilization depth also varies. However, conventional fertilization devices have a relatively fixed fertilization depth, which makes the fertilization depth consistent for different soil structures. This leads to a mismatch between the fertilization depth and the crop root system, reducing fertilizer utilization and making it difficult to achieve precise fertilization. Therefore, it is necessary to provide a sandy soil deep fertilization device to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0030] like Figures 1-2 As shown, this application provides a deep fertilization device for sandy land, including a support device. The support device has a rectangular support frame 1 and a support plate, forming a frame. Two sets of support rods 11 are fixed outwardly at the lower end of one side of the support frame 1, and the lower ends of the two sets of support rods 11 are rotatably connected to drive wheels 12. Two sets of auxiliary rods 13 are fixed in the same inclination direction as the support rods 11 on the other side of the support frame 1, and the lower ends of the auxiliary rods 13 are rotatably connected to auxiliary wheels 14. At the same time, a handle 15 is also fixedly installed on the side of the support frame 1, so the operator can easily push the entire support device by holding the handle 15 through the drive wheels 12 and auxiliary wheels 14. In this application, a trailer can also be connected to the other side of the support frame 1, and the support device can be moved more conveniently by the trailer.

[0031] Meanwhile, a fertilizer storage hopper 2 is fixedly installed at the center of the support frame 1. The lower end of the fertilizer storage hopper 2 is connected to a discharge pipe 21. In this application, a butterfly valve (not shown in the figure) is provided on the discharge pipe 21. This butterfly valve is prior art and can control the discharge amount of the discharge pipe 21.

[0032] Furthermore, two sets of inclined plates 16 are fixedly installed on the lower end of the support frame 1 near the handle 15. The two sets of inclined plates 16 are hinged to scrapers 17 on the side away from the feed pipe 21. The scrapers 17 can be used to backfill sand.

[0033] like Figures 2-3 As shown, in order to facilitate the precise application of fertilizer in the fertilizer storage hopper 2, a ditching mechanism 3 is provided on one side of the support frame 1. The ditching mechanism 3 has a protective cover 31 fixedly installed on the support frame 1. The protective cover 31 is located between the upper ends of the auxiliary rods 13. At the same time, a connecting rod 32 is also provided at the lower end of the support frame 1. The connecting rod 32 is located on one side of the protective cover 31. A drive box 33 is fixedly installed at the lower end of the connecting rod 32. A turntable 34 is rotatably connected to one side of the drive box 33. Plow blades 35 are evenly fixedly installed on the outer end of the turntable 34. The plow blades 35 are located at the lower end of the protective cover 31. Therefore, pushing the support device as a whole can drive the turntable 34 and the plow blades 35 to rotate, so as to ditch the sandy land. At the same time, the protective cover 31 prevents sand and soil from splashing during the ditching process.

[0034] like Figures 3-4 As shown, in order to adjust the height of the trenching mechanism 3, a fixing sleeve 36 is fixedly installed at the corner of the support frame 1 directly above the drive box 33. In this application, a mating groove is provided on the inner wall of the fixing sleeve 36, and a mating strip is provided on the outer side of the connecting rod 32. The mating strip and the mating groove cooperate with each other, so the connecting rod 32 is slidably connected to the mating groove in the fixing sleeve 36 through the mating strip, preventing the connecting rod 32 from rotating left and right during the up and down sliding process.

[0035] Meanwhile, a fixing hole 361 is provided through the lower end of the fixing sleeve 36, and multiple sets of mating holes 331 are provided through the connecting rod 32. The mating holes 331 and the fixing holes 361 correspond to each other. A bolt 37 is provided in the fixing hole 361 and one set of mating holes 331. A nut 38 is threaded onto the bolt 37. Therefore, by passing the bolt 37 through the fixing hole 361 and the mating hole 331 and then tightening the nut 38, the connecting rod 32 is fixed.

[0036] Furthermore, an external thread 22 is provided on the outside of the feed pipe 21, and an extension sleeve 23 is threaded onto the external thread 22. Therefore, by rotating the extension sleeve 23, the length of the feed pipe 21 is extended so that the fertilizer can directly reach the furrow.

[0037] In summary: When fertilizing the soil in different areas, first unscrew the nut 38 and remove the bolt 37. Then slide the connecting rod 32 in the fixing sleeve 36 to adjust the depth of the plow blade 35. After the connecting rod 32 is connected to the appropriate position, install and tighten the bolt 37 and nut 38 to fix the connecting rod 32. Then, tighten the extension sleeve 23 to make its height level with the plow blade 35, so that the fertilizer can directly reach the furrow.

[0038] Then, the drive wheel 12 and auxiliary wheel 14 are rotated by manually pushing the handle 15 or by pushing a cart, so that the plow blade 35 rotates and opens the furrow. Then, the butterfly valve on the feed pipe 21 is opened, so that the fertilizer in the fertilizer storage hopper 2 falls down. The scraper 17 scrapes the sand and buries the fertilizer, thus completing the fertilization needs of different depths in the sandy land, preventing the fertilization depth from being mismatched with the crop root system, improving fertilizer utilization, and achieving precision fertilization.

[0039] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
