Description

Technical Field

[0001] The utility model relates to the technical field of water-fertilizer integration, in particular to a water-fertilizer mixing integrated machine based on a Venturi ejector. Background Art

[0002] The integrated water and fertilizer machine can quantify fertilizers according to the needs of different crops and different soil environments, so that fertilization is carried out completely in accordance with the needs of crops, improving fertilizer utilization and crop yield and quality. However, due to its high cost and the need for a large number of supporting peripheral facilities, its promotion is slow. Currently, only large-scale specialized bases and agricultural demonstration areas are equipped with it;

[0003] In the prior art, a Chinese patent with publication number CN206993967U discloses a nutrient solution secondary mixing type water-fertilizer integrated machine, including a frame, a mixing barrel, a fertilizer pump and a control system installed on the frame, the fertilizer pump is connected to a pumping pipe and an output pipe connected to the mixing barrel, and a main valve is installed on the output pipe; the frame is also connected to a water inlet pipe connected to the upper end of the mixing barrel and arranged parallel to the water collecting pipe, one end of the water inlet pipe is connected to the output pipe, and multiple mixing pipes are connected in parallel between the water inlet pipe and the water collecting pipe, each mixing pipe is also connected in series with a Venturi water ejector, and each Venturi water ejector suction port is connected to a fertilizer suction pipe, and the fertilizer suction pipe is connected in series with a flow meter and an electric regulating valve, and the electric regulating valve is electrically connected to the control system; the control system is also electrically connected to a sensor device for detecting the pH value and EC value of the liquid in the mixing barrel. The water-fertilizer integrated machine can select the corresponding fertilizer ratio scheme according to different crops, and can accurately ensure the stability of the nutrient solution components, and has high preparation efficiency;

[0004] The mixing device in the current integrated water-fertilizer machine is relatively expensive. The mixing device is replaced by a Venturi ejector. The Venturi ejector is a conveying device that uses a Venturi tube and a vacuum device to extract air from the water flow flowing in the tube to enhance the water pressure. The use of a Venturi ejector can reduce the price of the integrated water-fertilizer machine. As the integrated water-fertilizer machine is used for a long time, fertilizer residue will remain on the inner wall of the bucket. If the fertilizer on the inner wall is not cleaned for a long time, it will clump, causing fertilizer waste and affecting the utilization rate of the fertilizer. Utility Model Content

[0005] The purpose of the utility model is to provide a water-fertilizer mixing integrated machine based on a Venturi ejector to solve the problems raised by the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A water-fertilizer mixing machine based on a Venturi ejector, comprising:

[0008] A fixed plate, one side of which is provided with a plurality of evenly spaced connection blocks, one side of the plurality of connection blocks is connected with a water inlet pipe, the outer surface of the water inlet pipe is provided with a plurality of evenly spaced water outlet pipes, and the interior of the water outlet pipe is provided with a Venturi ejector;

[0009] A fertilizer storage bucket, the fertilizer storage bucket is connected to one end of the water inlet pipe, two groups of symmetrically distributed motor fixing frames are arranged on the upper surface of the fertilizer storage bucket, a motor is arranged between the two groups of motor fixing frames, a stirring rod is connected to the lower surface of the motor, and the stirring rod is arranged inside the fertilizer storage bucket;

[0010] A cleaning component is arranged inside the fertilizer storage water barrel.

[0011] Preferably, a matching water outlet is provided at one end of the water outlet pipe, and a water valve is provided on the outer surface of the water outlet pipe;

[0012] A matching filter screen is arranged inside one end of the water inlet pipe, and one end of the water inlet pipe is connected with the inside of the fertilizer storage bucket.

[0013] Preferably, two groups of symmetrically distributed connecting rods are fixedly connected to the outer surface of the stirring rod;

[0014] Two groups of fan blades evenly spaced are sleeved between the two groups of connecting rods;

[0015] A matching shaft groove is provided at the upper end of the fertilizer storage water bucket, and the stirring rod is arranged inside the shaft groove through the coordinated rotation of the motor. A fixed groove is provided at the bottom of the fertilizer storage water bucket, and the stirring rod rotates inside the fixed groove.

[0016] Preferably, the cleaning assembly includes a connecting rod, each of which has a sliding rod groove at one end, a matching sliding rod is slidably arranged inside the sliding rod groove, a matching elastic member is arranged between a side wall of the sliding rod and an inner side wall of the sliding rod groove, and the sliding rod is elastically inserted into the interior of the sliding rod groove through the elastic member.

[0017] Preferably, one end of the sliding rod is fixedly connected to a cleaning rod, and both sides of the cleaning rod are beveled surfaces;

[0018] A plurality of groups of evenly spaced trapezoidal blocks are fixedly arranged at positions corresponding to the cleaning rods inside the fertilizer storage water barrel, and both sides of each of the trapezoidal blocks are chamfered surfaces.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] The utility model transports the water and fertilizer in the fertilizer storage bucket to the inside of the water outlet pipe through the water inlet pipe, and then the water and fertilizer flow through the venturi ejector in the water outlet pipe, and finally flow out of the position where fertilizer is needed through the water outlet;

[0021] By starting the motor, the fan blades on the stirring rod are driven to rotate, so that the water and fertilizer inside the fertilizer storage bucket can be fully stirred to avoid uneven fertilization. At the same time, the connecting rod also rotates, thereby driving the cleaning rod to rotate close to the inner wall of the fertilizer storage bucket, so that the fertilizer adhered to the inner wall of the fertilizer storage bucket can be cleaned, thereby improving the utilization rate of the fertilizer. When the cleaning rod passes through the trapezoidal block, because both sides of the cleaning rod and the trapezoidal block are beveled surfaces, the beveled surface on one side of the cleaning rod continues to slide along the beveled surface on one side of the trapezoidal block. When the cleaning rod slides over the trapezoidal block, the cleaning rod is hit against the inner wall of the fertilizer storage bucket through the force of the elastic member, and then the small fertilizer particles remaining on the inner wall of the fertilizer storage bucket are hit, thereby improving the utilization rate of fertilizer.
