Description

Technical Field

[0001] The utility model relates to the technical field of agricultural irrigation, in particular to a soil conditioner application device. Background Art

[0002] The Venturi fertilizer applicator is an agricultural equipment based on soil moisture transmission. It can automatically complete the functions of irrigation and fertilization. It provides the most suitable growth environment for crops by accurately controlling the moisture and nutrients in the soil. In the field of soil conditioner application, it can achieve precise fertilization, improve the utilization rate of soil conditioners, promote the mixing between soil conditioners and soil, and improve the quality and yield of crops.

[0003] When the existing Venturi fertilizer spreader is in operation, the end of its liquid inlet pipe often has problems due to pressure difference or excessive internal hydraulic strength. Specifically, the position of the end filter in the fertilizer mixing barrel is unstable, which interferes with the effective extraction of liquid fertilizer at the bottom of the fertilizer mixing barrel. In order to solve this problem, a common practice is to fix a heavy object, such as a stone, at the end to ensure that the filter is always sunk to the bottom of the fertilizer mixing barrel. However, although this method is simple, it sacrifices the mobility of the filter. Every time the filter needs to be moved or repaired, the operator must laboriously salvage the heavy object, which not only increases the difficulty of operation, but also reduces the overall practicality of the equipment. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a soil conditioner application device to solve the technical problem that the traditional fixing form of the filter increases the difficulty of operation.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a soil conditioner application device, comprising an irrigation main pipe, a venturi fertilizer applicator and a fertilizer mixing barrel, the venturi fertilizer applicator is connected to a second infusion pipe through a second control valve, the other end of the second infusion pipe is connected to a steel pipe, a fixing mechanism is provided on the outside of the steel pipe, the fixing mechanism includes a bottom plate, a filter is detachably connected to the end of the steel pipe, a magnetic block is provided at the bottom of the filter, and a stainless steel plate is provided at the inner bottom of the fertilizer mixing barrel.

[0006] By adopting the above technical solution, this magnetic fixing method is conducive to ensuring the stable position of the filter inside the fertilizer mixing barrel. By adjusting the magnetic attraction strength between the magnetic block and the stainless steel plate, the filter can be fixed according to actual needs to prevent it from moving during use, thereby ensuring the stability of liquid fertilizer extraction and the uniformity of fertilization.

[0007] Furthermore, a plurality of support plates are arranged on the top of the bottom plate, and the plurality of support plates are arranged in an equidistant ring shape along the central axis of the bottom plate.

[0008] By adopting the above technical solution, the arrangement of multiple support sheets provides a stable structural support, and these support sheets can evenly distribute the weight of the filter and its accessories, thereby ensuring the stability of the entire fixing mechanism.

[0009] Furthermore, filters are detachably connected between adjacent support sheets.

[0010] By adopting the above technical solution, the detachable connection design enables the filter to be easily installed, replaced and cleaned, which helps to maintain the filtering effect of the filter and prevent clogging, thereby ensuring the smooth operation of the entire fertilization device.

[0011] Furthermore, a top cover is provided on the top of the filter, and a plurality of through slots are opened on the surface of the top cover, and the number of the through slots is the same as that of the support sheet and the positions are opposite.

[0012] By adopting the above technical solution, such a design enables the support sheet to smoothly pass through the through slot and be connected and fixed to the filter. This structure not only ensures the stability of the filter, but also facilitates the installation and removal of the support sheet.

[0013] Furthermore, a card and a limiting plate are arranged on the inner side of the supporting plate, and the top end of the supporting plate passes through the top cover through a through slot and is engaged with the card.

[0014] By adopting the above technical solution, the design of the card and the limit plate enables the support plate to be firmly fixed on the top cover. When the top end of the support plate passes through the through slot of the top cover, the card will engage with the top cover to prevent the support plate from falling off the top cover.

[0015] Furthermore, a threaded ring is provided at the center axis of the top cover, the threaded ring and the steel pipe are coaxially arranged, and the threaded ring and the steel pipe are sleeved and slidably arranged.

[0016] By adopting the above technical solution, the coaxial line setting ensures that the top cover and the supporting plate underneath it can slide up and down smoothly along the steel pipe. This design allows the height position of the filter to be adjusted as needed to adapt to different working scenarios.

[0017] Furthermore, the outer side of the threaded ring is threadedly connected with a fastening sleeve.

[0018] By adopting the above technical solution, the fastening sleeve is connected to the outside of the threaded ring through threads. This connection method can provide reliable fastening force, ensure that the position of the top cover on the steel pipe is stable and will not move due to liquid flow impact or other external forces.

[0019] Furthermore, the top cover, bottom plate and support sheet are all made of PVC corrosion-resistant material.

[0020] By adopting the above technical solution, the PVC corrosion-resistant material can resist the erosion of chemical substances such as fertilizers and pesticides, thereby ensuring that the top cover, bottom plate and support sheet are not easily damaged or deformed during long-term use.

[0021] Furthermore, the irrigation main pipe is connected in parallel with the Venturi fertilizer applicator, and a main valve and a first control valve are provided on the irrigation main pipe.

[0022] By adopting the above technical solution, the parallel connection design of the irrigation main pipe and the Venturi fertilizer applicator allows water to flow through the irrigation main pipe and the fertilizer applicator at the same time, ensuring that the farmland can still receive a continuous and uniform water supply during the fertilization process.

[0023] Furthermore, the other end of the first control valve is connected to the fertilizer mixing barrel through a first liquid infusion tube.

[0024] By adopting the above technical solution, the setting of the first control valve can control the open or short circuit of the first infusion pipe. When fertilizer mixing operation is required, the first control valve can be opened to divert the water flow inside the irrigation main pipe until it flows into the fertilizer mixing barrel, and the fertilizer mixing operation of water and solid and powdery soil conditioners can be completed.

[0025] In summary, the utility model mainly has the following beneficial effects:

[0026] 1. The utility model can ensure the stable position of the filter in the fertilizer mixing barrel by means of a fixing mechanism and a magnetic fixing method. Due to the effect of magnetic force, the position limitation of the filter is improved, thereby avoiding the position movement caused by liquid flow impact or other factors, ensuring the stability of liquid fertilizer extraction and the uniformity of fertilization;

[0027] 2. The utility model allows the user to easily adjust the height position of the filter to adapt to different working requirements by setting a threaded sleeve and a sliding threaded ring. This height adjustability ensures that the filter can perform filtering operations at the optimal position to improve the filtering effect. At the same time, by adjusting the distance between the magnetic block and the stainless steel plate, the magnetic attraction force can be accurately controlled. This adjustment method ensures that the filter is firmly fixed and avoids the problem of inconvenience in operation or fixation failure caused by too tight or too loose magnetic attraction.
