Description

Technical Field

[0001] The present invention relates to the technical field of agricultural water and fertilizer integration equipment detection, and specifically relates to a mother liquid barrel for detecting agricultural water and fertilizer integration equipment. Background Technique

[0002] At present, the agricultural water and fertilizer integration technology has been popularized and applied. The water and fertilizer integration equipment can accurately configure fertilizers, regulate the concentration of irrigation fertilizer solution and irrigation flow rate, realize the uniform consistency of water and fertilizer integration in time and space, effectively improve the water and fertilizer utilization efficiency, reduce fertilizer waste, and thus alleviate the non-point source pollution problem caused by agricultural production. However, at present, the performance of water and fertilizer integration equipment is uneven, lacking standardized detection methods and automated performance detection platforms. The detection platform can provide stable and standard water source test conditions for the detection and operation of water and fertilizer integration equipment, provide stable and uniform fertilizer mother liquid, and detect and record key data such as pipeline flow rate, pressure, mother liquid flow rate, and fertilizer mixing concentration in real time.

[0003] At present, the fertilizer mother liquid barrel used in the detection platform is a general barrel-shaped container, which has three problems. First, when changing the type of mother liquid, the remaining liquid and impurities cannot be drained completely, affecting the next set of test conditions. Second, it is difficult to detect the flow rate online. The commonly used pipeline flow sensors have large errors, and the mother liquid concentration is high, which is easy to crystallize and deposit at the sensitive elements, affecting the detection. Third, the mother liquid mixing requires manual stirring or motor-driven paddle stirring. Motor-driven paddle stirring will block the fertilizer inlet, restricting the fertilizer addition efficiency. The mixing time in winter low-temperature tests is too long, affecting the test process. The overall automation degree of the water and fertilizer integration equipment detection platform is relatively high, but the mother liquid barrel device is still a short board, and there is an urgent need for a mother liquid barrel device that can drain the remaining materials, accurately monitor the flow rate, and dissolve fertilizers at high speed. Summary of the Invention

[0004] (1) Technical Problems to be Solved

[0005] In view of the deficiencies of the prior art, the present invention provides a mother liquid barrel for detecting agricultural water and fertilizer integration equipment. By setting the bottom as a convex frustum shape and installing a three-way joint, the traditional stirring by a motor-driven paddle is changed to stirring by a submersible pump, adding a heating device, and setting a pressure sensor, which improves the mixing and dissolution speed of water and fertilizer and the detection efficiency, and solves the technical problems of low mother liquid mixing efficiency, difficult cleaning of the mother liquid barrel, and difficult detection in the prior art.

[0006] (2) Technical Solutions

[0007] To achieve the above object, the present invention provides the following technical solution: A mother liquor bucket for detecting agricultural water and fertilizer integration equipment, including a mixing liquid bucket main body and a chassis. The bottom of the mixing liquid bucket main body is a downward convex frustum shape, and a three-way joint is installed at the center position of the bottom plane of the frustum. A weighing base is installed on the surface of the downward convex frustum-shaped bottom of the mixing liquid bucket main body. The weighing base is located above the chassis. A mixing device is installed on one side of the bottom of the mixing liquid bucket main body, and a heating device is wrapped on the outer wall surface of the mixing liquid bucket main body.

[0008] Further, the cylindrical main body of the mixing liquid bucket is made of black hard plastic, and the diameter of the upper barrel mouth of the mixing liquid bucket main body is not less than 80% of the cross-sectional diameter of the cylindrical main body.

[0009] Further, a water inlet is installed on the upper barrel shoulder of the cylindrical main body of the mixing liquid bucket main body. An elbow is provided at the end of the water inlet, and the water inlet direction of the water inlet is perpendicular to the diagonal line of the barrel shoulder, so that the water inlet forms a natural counterclockwise rotation, accelerating the dissolution of fertilizers.

[0010] Further, one side of the three-way joint is connected to the suction port of the device to be tested, and the other side is connected to a valve to the drainage system.

[0011] Further, a liquid level display is installed on one side of the mixing liquid bucket main body for observing the mother liquor level of the mixing liquid bucket main body. A pair of liquid level warning sensors are symmetrically arranged at the upper and lower ends of the liquid level display for alarming when the mother liquor level in the mixing liquid bucket main body is too high or too low.

[0012] Further, the weighing base is circular ring-shaped, and its inner side surface is sloped. The inner surface of the weighing base fits with the surface of the downward convex frustum-shaped bottom of the mixing liquid bucket main body. A round hole is opened at the center of the downward convex frustum-shaped bottom for conveniently collecting undissolved impurities and discharging them from the impurity discharge port. Corresponding to the round hole opened at the bottom of the mixing liquid bucket main body, it is used to install the three-way joint;

[0013] Further, the mixing device includes a placement table installed at the bottom of the mixing liquid bucket main body. The height of the placement table is one-fifth of the height of the mixing liquid bucket main body. A submersible pump is fixedly installed on the placement table. The outlet of the submersible pump is along the oblique cutting direction of the downward convex frustum shape at the bottom of the mixing liquid bucket main body, so that the mother liquor in the mixing liquid bucket main body rotates counterclockwise, accelerating dissolution.

[0014] Further, the heating device includes an electric heating film wrapped on the outer wall of the mixing liquid bucket main body. The electric heating film is located in the area of one-third of the mixing liquid bucket main body for accelerating the dissolution of the mother liquor in a low-temperature environment.

[0015] Furthermore, three or four pressure sensors are evenly distributed between the weighing base and the chassis. The pressure sensors are used to accurately detect the mass change of the mother liquid barrel in real time through bridging, monitor the mass change of the mother liquid in the mother liquid barrel through data in real time, and calculate the mother liquid usage through the difference, so as to monitor the fertilizer absorption amount of the water and fertilizer integrated machine.

Corresponding to the circular hole opened at the bottom of the mixing liquid barrel main body 1, it is used for installing the three-way joint 3; A mixing device 5 is installed on one side of the bottom of the mixing liquid barrel main body 1. The mixing device 5 includes a placement table 501 installed on the bottom of the mixing liquid barrel main body 1. The height of the placement table 501 is one-fifth of the height of the mixing liquid barrel main body 1. A submersible pump 502 is fixedly installed on the placement table 501. The outlet of the submersible pump 502 is along the oblique cutting direction of the downward convex frustum shape at the bottom of the mixing liquid barrel main body 1, making the mother liquid in the mixing liquid barrel main body 1 rotate counterclockwise, accelerating dissolution; The outer wall surface of the mixing liquid barrel main body 1 is wrapped with a heating device 6; The heating device 6 includes an electric heating film 601 wrapped on the outer wall of the mixing liquid barrel main body 1.
