Description

Technical Field

[0001] The utility model belongs to the technical field of water-fertilizer integration, and in particular relates to a water-fertilizer ratio control device for water-fertilizer integration. Background Art

[0002] Water-fertilizer integration technology refers to a new agricultural technology that integrates irrigation and fertilization. Water-fertilizer integration is to use a pressure system (or natural terrain drop) to mix soluble solid or liquid fertilizers according to the soil nutrient content and the fertilizer requirements and characteristics of the crop types. The fertilizer solution is mixed with irrigation water and supplied through a controllable pipeline system. After the water and fertilizer are mixed, drip irrigation is formed through pipes and drippers to evenly, regularly and quantitatively infiltrate the root development and growth area of ​​the crop, so that the main root soil always maintains looseness and appropriate water content; at the same time, according to the fertilizer requirements of different crops, soil environment and nutrient content, the water requirements of crops in different growth periods, and the fertilizer requirements, the demand design for different growth periods is carried out, and water and nutrients are provided to crops directly in a regular and quantitative manner in proportion. When the amount to be allocated is large, a proportional control device is required for regulation.

[0003] The integrated water-fertilizer ratio control device disclosed in Chinese patent CN218789097U can achieve the purpose of quantitative feeding each time by pouring a sufficient amount of fertilizer into the inner wall of the trough through the feeding funnel and fixing the amount of fertilizer by the volume of the trough. However, the integrated water-fertilizer ratio control device has the following defects while solving the problem:

[0004] 1. The device puts fertilizer in by pressing. If the spring force is too large, there is always a force to push the fertilizer away. It is necessary to continuously press the fertilizer to make it enter the trough. At the same time, it is also necessary to control the flipping of the trough, which is inconvenient to operate. If the spring force is too small, it is easy to fail to push the push plate to push out the wet fertilizer, which is inconvenient to use.

[0005] 2. The device puts the fertilizer in the trough into the auger barrel in batches through the rotation of the turntable, and then sends it into the mixing barrel through the rotation of the auger. The auger is prone to blockage in the case of non-continuous feeding and when the fertilizer is wet, which makes the device prone to blockage when in use and unable to feed, and has poor practicality. Utility Model Content

[0006] The technical problem to be solved by the utility model is that the fertilizer needs to be continuously pressed to make it enter the trough, and at the same time, the trough needs to be controlled to flip, which is inconvenient to operate. In view of the shortcomings of the prior art, a water-fertilizer ratio control device with integrated water-fertilizer is provided, including a mixing box, a quantitative component and a cleaning component. The top of the mixing box is fixedly connected with a quantitative cylinder, the interior of the quantitative cylinder is rotatably provided with a separating impeller, the surface of the quantitative cylinder is provided with a feeding box, the top of the mixing box is provided with a water source pipe, one end of the water source pipe is fixedly installed with a flow meter, the water outlet of the flow meter is fixedly installed with an injection pipe, one end of the injection pipe is connected with the interior of the mixing box; the cleaning component is used to clean the fertilizer adhered to the separating impeller.

[0007] Furthermore, another water outlet of the flow meter is fixedly installed with a pump inlet pipe, the cleaning component includes a water pump fixedly installed at one end of the pump inlet pipe, and the outlet of the water pump is fixedly installed with a pump outlet pipe.

[0008] Furthermore, the dividing impeller includes an arc-edged diamond column located at the axis of the metering cylinder and conveying blades located at the corners of the arc-edged diamond column, and the cleaning assembly includes a nozzle rack fixedly installed on the inner wall at the top of the mixing box, and a nozzle is provided on the side of the nozzle rack facing the metering cylinder, and one end of the nozzle rack passes through the mixing box and is fixedly installed at the water outlet end of the pump outlet pipe.

[0009] Furthermore, a motor frame is fixedly installed on the top of the mixing box, a motor is fixedly installed on the top of the motor frame, and an output end of the motor penetrates into the interior of the mixing box and a mixing blade is fixedly installed thereon.

[0010] Furthermore, a driving motor is fixedly mounted on one side of the mixing box, a first bevel gear is fixedly mounted on the output end of the driving motor, a driving shaft is fixedly mounted on one end of the dividing impeller, a second bevel gear is fixedly mounted on one side of the driving shaft, and the first bevel gear meshes with the surface of the second bevel gear.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. The separating impeller allows the fertilizer in the metering cylinder to enter the mixing box. When the fertilizer with high humidity is easy to stick, start the water pump, and the water pump pumps water out through the pump outlet pipe at a high pressure. The fertilizer stuck to the separating impeller is cleaned through the cleaning component to avoid blockage, which is more convenient to use.

[0013] 2. The fertilizer enters the metering cylinder. At this time, the fertilizer enters between two sets of adjacent conveying blades. Then the dividing impeller is rotated to make the fertilizer enter the intersection area of ​​the metering cylinder and the mixing box. The pressure of the water pump is used to flush the conveying blades with the nozzle rack. When the water flow passes through the arc edge of the arc-edged diamond column, it turns from horizontal to vertical, so that the contact surface between the dividing impeller and the fertilizer is cleaned. The contact part between the conveying blade and the fertilizer is flushed with high-pressure water flow to avoid the adhesion of the fertilizer when the device is used, which makes it impossible to feed. It is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS
