Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, and in particular relates to a solid-liquid fertilizer dual-purpose fertilizer spreader. Background Art

[0002] my country, a major agricultural country, is vigorously promoting integrated water and fertilizer technology. This involves utilizing piped irrigation systems to dissolve fertilizer in water, simultaneously irrigating and fertilizing crops, meeting their water and nutrient needs in a timely and appropriate manner, and achieving synchronized management and efficient utilization of water and fertilizer. Modern agriculture, driven by new rural construction and intensive agricultural production, is the development direction of my country's rural and agricultural sectors. Modernizing agricultural equipment is a key means of achieving agricultural modernization. Coupled with the large-scale transfer of rural labor, precision fertilization and controlled fertilization technologies will be vigorously promoted and widely applied. Therefore, in conjunction with the promotion of integrated water and fertilizer technology and the large-scale construction of water-saving irrigation systems in my country, a liquid fertilizer applicator is needed.

[0003] Existing fertilizer spreaders use a booster pump to extract liquid fertilizer from a fertilizer tank and transport it to the drip irrigation waterway through a stainless steel pipe to perform water-fertilizer mixed drip irrigation. However, they are limited to lightweight fertilizers and cannot be used for liquid fertilizers with higher fertilizer efficiency, nor can they use the powder fertilizers commonly used by farmers for water-soluble fertilizer fertilization. At the same time, water-soluble fertilizers have a lower fertilizer concentration due to the need to add water and stir, and the fertilizer flow rate is quite different from that of liquid fertilizers, making it impossible to use a single device for fertilization. In response to the above problems, the present utility model provides a solid-liquid dual-purpose fertilizer spreader with a simple structure, ingenious design, and the ability to achieve precise control. It is also suitable for drip irrigation pipeline fertilization of concentrated liquid fertilizers and powder fertilizers, reducing power consumption and saving labor and material costs.

DETAILED DESCRIPTION

[0029] The solid and liquid fertilizer dual-purpose fertilizer applicator provided by this application is as follows Figures 1 to 3 As shown, it includes a fertilizer pipe 2, a liquid fertilizer delivery system, a water-soluble fertilizer delivery system, and a cleaning system. Liquid fertilizer refers to fertilizer in liquid form (generally emulsified by high-speed shearing), and water-soluble fertilizer refers to solid fertilizer that can be dissolved in water (including granular fertilizer, powder fertilizer, etc.). When used, the solid fertilizer is first dissolved in water before being delivered.

[0030] One end of the liquid fertilizer delivery system is connected to a liquid fertilizer storage tank during use to absorb liquid fertilizer, and the other end is connected to a fertilizer pipe 2 to deliver the absorbed liquid fertilizer to the fertilizer pipe 2. The water outlet of the fertilizer pipe 2 can be connected to a field irrigation waterway, and fertilizer is applied through the fertilizer pipe 2. The liquid fertilizer delivery system includes a liquid fertilizer delivery pipeline 3, a liquid fertilizer fertilization valve 9, and a liquid fertilizer one-way valve 11 provided on the liquid fertilizer delivery pipeline; the liquid fertilizer one-way valve 11 is located at the tail end of the liquid fertilizer delivery pipeline. The liquid fertilizer delivery pipeline 3 is used for the flow and delivery of liquid fertilizer, and the liquid fertilizer fertilization valve 9 is used to control the interruption and connection of the liquid fertilizer delivery pipeline. That is, by switching the liquid fertilizer fertilization valve, the start or interruption of liquid fertilizer delivery can be controlled. The liquid fertilizer one-way valve 11 is used to ensure that the fertilizer liquid in the liquid fertilizer delivery pipeline flows in one direction to the fertilizer pipe 2, which can prevent the fertilizer liquid from flowing back.

[0031] One end of the water-soluble fertilizer delivery system is connected to the water-soluble fertilizer storage tank when in use, and is used to absorb water-soluble fertilizer, and the other end is connected to the fertilizer pipe 2 to deliver the absorbed water-soluble fertilizer to the fertilizer pipe 2, and fertilize it through the fertilizer pipe 2 like liquid fertilizer. A stirring device may be provided in the water-soluble fertilizer storage tank to promote the dissolution of solid fertilizer. The water-soluble fertilizer delivery system includes a water-soluble fertilizer delivery pipeline 4 and a water-soluble fertilizer fertilization valve 8 and a water-soluble fertilizer one-way valve 12 arranged on the water-soluble fertilizer delivery pipeline; the water-soluble fertilizer one-way valve 12 is located at the tail end of the water-soluble fertilizer delivery pipeline. The water-soluble fertilizer delivery pipeline 4 is used for the flow delivery of water-soluble fertilizer, and the water-soluble fertilizer fertilization valve 8 is used to control the start or interruption of water-soluble fertilizer delivery. The water-soluble fertilizer one-way valve 12 is used to allow the fertilizer liquid in the water-soluble fertilizer delivery pipeline to flow unidirectionally to the fertilizer pipe, which can prevent the fertilizer liquid from flowing back.

[0032] Since the liquid fertilizer and water-soluble fertilizer in this application are finally transported to the fertilizer pipe 2 for fertilization, a one-way valve is set at the end of the liquid fertilizer delivery pipeline and the water-soluble fertilizer delivery pipeline, which can effectively prevent the fertilizer liquid in the fertilizer pipe from flowing back into different delivery pipelines and causing the liquid fertilizer and water-soluble fertilizer to mix, affecting the accuracy of fertilization.

[0033] The cleaning system is connected to the liquid fertilizer delivery system and the water-soluble fertilizer delivery system and is used to clean residual fertilizer liquid from these systems. Nutrients from liquid and water-soluble fertilizers may precipitate and clog the pipelines during delivery, effectively preventing blockage.

[0034] The dual-purpose fertilizer spreader for solid and liquid fertilizers also includes several flow meters 7 and a delivery pump. The flow meters are used to detect and control the delivery rate of liquid fertilizer and / or water-soluble fertilizer to achieve precise fertilization. The delivery pump is used to provide power to deliver liquid fertilizer and water-soluble fertilizer.

[0035] The flow meter and delivery pump can be set up in any of the following ways:

[0036] a. There is one delivery pump and one flow meter, both located on the fertilizer pipe. Since the fertilizer pipe can deliver two types of fertilizers, the delivery pump and flow meter are installed on the fertilizer pipe to deliver liquid fertilizer and water-soluble fertilizer, as well as to detect and adjust the delivery flow.

[0037] b. Two delivery pumps and flowmeters are provided: one delivery pump (liquid fertilizer pump 6) and flowmeter 7 are located on the liquid fertilizer delivery pipeline, and the other delivery pump (water-soluble fertilizer pump 5) and flowmeter are located on the water-soluble fertilizer delivery pipeline. This arrangement allows for separate control of liquid and water-soluble fertilizer delivery and flow regulation. As described in the background, the delivery rates of liquid and water-soluble fertilizers generally differ significantly, making this arrangement preferable to method a.

[0038] c. There are two delivery pumps, one located on the liquid fertilizer delivery pipeline, and the other located on the water-soluble fertilizer delivery pipeline; the delivery of liquid fertilizer and water-soluble fertilizer can be controlled separately.

[0039] There is one flow meter located on the liquid fertilizer delivery pipeline, meaning only the liquid fertilizer flow rate can be monitored and adjusted. Water-soluble fertilizers are generally less efficient, so flow regulation is less important than for liquid fertilizers and can be omitted in some embodiments.

[0040] When the present application is used, liquid fertilizer can be applied by opening the liquid fertilizer application valve 9 and closing the water-soluble fertilizer application valve 8, and vice versa. It is also possible to simultaneously open the liquid fertilizer application valve 9 and the water-soluble fertilizer application valve 8 to simultaneously apply liquid fertilizer and water-soluble fertilizer. Therefore, the fertilizer applicator provided by the present application can simultaneously apply water-soluble fertilizer and liquid fertilizer in a single machine, can adjust the fertilization speed, reduce power consumption, and save labor and material costs.

[0041] The positions of the delivery pump and the flow meter can be adjusted according to the actual application situation. Preferably, the liquid fertilizer fertilization valve, the delivery pump, the flow meter and the liquid fertilizer one-way valve are arranged in sequence along the liquid fertilizer delivery direction.

[0042] Preferably, the water-soluble fertilizer delivery system also includes a first pressure transmitter 13. Because water-soluble fertilizer, unlike liquid fertilizer, undergoes high-speed shear emulsification, nutrients are more likely to precipitate and potentially clog pipelines. Therefore, the first pressure transmitter is provided in the water-soluble fertilizer delivery system to monitor the pressure of the water-soluble fertilizer delivery pipeline and promptly detect any blockages. Furthermore, since water-soluble fertilizer delivery typically involves high flow rates and high water pressure, the first pressure transmitter can also monitor pipeline water pressure to prevent damage from excessive pressure.

[0043] Further preferably, along the conveying direction of the water-soluble fertilizer conveying system, the water-soluble fertilizer fertilizing valve, the delivery pump, the first pressure transmitter and the water-soluble fertilizer one-way valve are arranged in sequence.

[0044] Preferably, the cleaning system includes a cleaning pipe 1, an inlet valve 10, and a second pressure transmitter 14 located on the cleaning pipe. The water outlet of the cleaning pipe 1 is connected to the liquid fertilizer delivery system and the water-soluble fertilizer delivery system via a tee. Water in the cleaning pipe can flow through the tee to the liquid fertilizer delivery system and / or the water-soluble fertilizer delivery system to flush the pipelines and reduce nutrient residue.

[0045] Further preferably, the water outlet end of the cleaning pipe 1 is directly connected to the liquid fertilizer delivery pipeline 3 between the liquid fertilizer application valve and the liquid fertilizer one-way valve, and to the water-soluble fertilizer delivery pipeline 4 between the water-soluble fertilizer application valve and the water-soluble fertilizer one-way valve through a tee. With this arrangement, after the cleaning water flows through the tee to the liquid fertilizer delivery pipeline / water-soluble fertilizer delivery pipeline, it can flow simultaneously toward the liquid fertilizer application valve / water-soluble fertilizer delivery pipeline and the liquid fertilizer one-way valve / water-soluble fertilizer one-way valve, thereby fully flushing the pipelines.

[0046] The water-soluble fertilizer fertilization valve, liquid fertilizer fertilization valve and water inlet valve are preferably electric ball valves. The flow meter is preferably an electromagnetic flow meter.

[0047] Preferably, the fertilizer spreader provided in the present application further includes a shell, and the fertilizer pipe, liquid fertilizer delivery system, water-soluble fertilizer delivery system and cleaning system are all installed in the shell and protected by the shell to isolate them from the influence of the external environment.

[0048] Each component provided in this application, such as the flow meter, one-way valve, fertilizer pipe, and fertilizer valve, is provided with quick connectors at both ends, through which the pipelines can be quickly connected.

[0049] Although preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they are aware of the basic inventive concepts. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention. Clearly, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, to the extent such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to encompass such changes and modifications.
