Description

Technical Field

[0001] The utility model relates to the technical field of pesticide stirring equipment, in particular to a pesticide stirring machine. Background Art

[0002] Pesticides are a general term for insecticides and herbicides used in the agricultural production process to protect and promote the growth of crops. Pesticides, as chemical products, usually need to be mixed to improve the insecticide and weed control effects. In order to improve the mixing efficiency and avoid precipitation of some powdered pesticides during use, the mixed pesticides usually need to be stirred. Since pesticides are mixed with ingredients that are harmful to the human body and easily volatile, long-term manual stirring will cause the operator to inhale the above-mentioned harmful gases, endangering human physical and mental health.

[0003] In order to solve the above problems, the prior art provides an agricultural pesticide stirring device, which arranges spiral blades in the shell to drive the cleaning plate to clean the pesticide residues attached to the inner wall of the shell. At the same time, the water flow impacts the fan blades, and the medicine drives the fan blades to rotate, thereby promoting the grinding rotation to grind and crush the particles on the sieve plate. The absorption efficiency is improved by increasing the contact area, and the speed at which the particles dissolve in water is accelerated. However, the device is large in size and complex in structure, which is inconvenient to carry, and requires an open place to store the equipment, which has high requirements on the environment. Utility Model Content

[0004] The purpose of the utility model is to solve the above problems in the existing technology and propose a pesticide mixer. The technical problem to be solved by the utility model is: how to simplify the structure and improve the portability.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a pesticide mixer, comprising a base, a filter screen and a cover plate, characterized in that the cover plate is erected above the base through the filter screen, and cooperates with each other to form a filter chamber, a water suction pipe that can be externally connected to the water inlet of a water pump is provided on the cover plate, and a mixing tube with two ends passing through is provided in the filter chamber, the mixing tube comprises a water inlet pipe, an air inlet pipe and an injection pipe, the air inlet pipe is located between the water inlet pipe and the injection pipe, the injection pipe passes through the filter screen and is connected to the outside world, a nozzle is connected between the water inlet pipe and the air inlet pipe, the water inlet pipe and the air inlet pipe are three-way pipes, the upper end of the water inlet pipe can be connected to the water outlet of the above-mentioned water pump, and the upper end of the air inlet pipe can be connected to the outside world.

[0006] The basic principle of the present application is to place the pesticide mixer into a container containing liquid, and the liquid enters the filter chamber through the filter screen, and then the liquid in the filter chamber is extracted by an external water pump on the water pump pipe, and pumped into the mixing tube, mixed with the external air, and then sprayed out from the injection pipes located at both ends of the mixing tube, thereby completing a cycle. Among them, the mixing tube also includes a water inlet pipe and an air inlet pipe. The pumped liquid is sprayed into the air inlet pipe through the water inlet pipe by the nozzle. Due to the fast injection speed, the internal air pressure is reduced to form a pressure difference. The external air enters the air inlet pipe under the influence of the pressure difference, and is mixed with the liquid in the air inlet pipe, and then is sprayed out from the injection pipe. After the operator adds powdered pesticide, the powdered pesticide and the liquid rotate together under the force generated by the jet sprayed from the injection pipe. The liquid in the air inlet pipe is rotated to accelerate the dissolution of the powdered pesticide. When part of the extremely fine powder enters the air inlet pipe along with the liquid from the water inlet pipe, a large amount of gas is mixed into the liquid at this time. Under the influence of the gas acetylene, the mixed gas causes the formed tiny bubbles to burst, so as to break up the micro-particles. While utilizing the force generated by the ejection of the ejection port to stir the internal liquid, the air inlet pipe is arranged between the water inlet pipe and the ejection port to complete the work of refining the particles. While ensuring that the same effect can be achieved, the mixing pipe composed of the water inlet pipe and the air inlet pipe is integrated in the filter chamber, thereby improving the integration, simplifying the structure, and reducing the size of the device. When in use, it only needs to be placed in a container to complete the stirring and refining work, thereby improving the portability of use.

[0007] In the above pesticide mixer, a plurality of filter holes are provided at the bottom of the base, and the filter holes are used to allow liquid to enter the filter chamber from the bottom surface. By providing the filter holes at the bottom of the base, the contact area between the filter chamber and the liquid in the barrel is increased, which facilitates the mixing to reach the bottom of the barrel and improves the mixing efficiency.

[0008] In the above-mentioned pesticide mixer, the injection pipe, the air inlet pipe and the nozzle are respectively located on both sides of the water inlet pipe.

[0009] In the above pesticide mixer, the air inlet pipe and the water inlet pipe are both located in the filter chamber, the injection pipe passes through the filter screen and is threadedly connected to the left or right end of the air inlet pipe, and the mixing pipe is clamped and fixed to one side of the injection pipe through the left or right end surface of the air inlet pipe. The injection pipe is fixed by clamping the air inlet pipe to prevent the mixing pipe from rotating during the stirring process, thereby improving the stability of the structure.

[0010] In the above pesticide mixer, the upper end of the water inlet pipe is threadedly connected with a straight pipe, the straight pipe is used to connect the water outlet of the water pump and the water inlet pipe, and the cover plate is clamped on the upper end surface of the straight pipe and the water inlet pipe. The cover plate is fixed by the cooperation of the water inlet pipe and the straight pipe. When the mixing tube is fixed to the filter screen and the base, it is prevented that debris enters the filter chamber through the cover plate and causes the internal water inlet pipe or nozzle to be blocked, so that it can be operated normally.

[0011] In the above pesticide mixer, a connecting pipe is provided at the upper end of the air inlet pipe, the air inlet pipe and the connecting pipe are threadedly connected, and the cover plate is clamped between the upper end surface of the air inlet pipe and the lower end surface of the connecting pipe. The cover plate is fixed by the cooperation between the air inlet pipe and the connecting pipe. When the mixing pipe is fixed to the filter screen and the base, it is prevented that debris enters the filter chamber through the cover plate and causes the internal water inlet pipe or nozzle to be blocked, so that it can be operated normally.

[0012] In the above pesticide mixer, the connecting pipe is provided with an air intake valve, and the air intake pipe is connected to the outside through the air intake valve. By providing the air intake valve on the connecting pipe, the air intake pipe is blocked, which affects normal use.

[0013] In the above-mentioned pesticide mixer, the spray head includes a connecting pipe and a nozzle, the water inlet pipe is connected to the air inlet pipe through the connecting pipe, the nozzle is located in the middle of the connecting pipe, and the end of the nozzle located in the air inlet pipe is truncated.

[0014] In the above-mentioned pesticide mixer, a connecting portion is provided on the cover plate, the cover plate is connected to the water pumping pipe via the connecting portion, and the connecting portion is threadedly connected to the water pumping pipe.

[0015] In the above-mentioned pesticide mixer, a nozzle is provided at the end of the spray pipe, and the nozzle is in a long strip shape and is arranged opposite to the base.

[0016] Compared with the prior art, the utility model has the following advantages:

[0017] 1. In the present application, the liquid in the filter chamber is extracted from the water suction pipe, pumped into the water inlet pipe, and mixed in the air inlet pipe through the nozzle, and then sprayed out through the injection pipe to complete the cycle. In the process of stirring by the jet sprayed from the injection pipe, the gas acetylene produced by the mixed air refines the particles, thereby further improving the dissolution efficiency.

[0018] 2. After the mixing tube is fixed to the filter screen and the base through the injection tube and the air inlet pipe, the stability of the cover during connection is further improved by clamping the water inlet pipe and the straight pipe as well as the air inlet pipe and the connecting pipe to prevent impurities from mixing into the filter chamber and causing blockage of the water inlet pipe.

[0026] like Figure 3 and Figure 4As shown, the cover plate 2, the filter screen 1a and the base 1 of the present application cooperate to form a filter chamber 5, and a plurality of filter holes 1b are provided at the bottom of the filter chamber 5, so that the bottom of the filter chamber 5 is connected to the outside, and a straight pipe 2b and a water pumping pipe 2a are provided above the cover plate 2, and a connecting pipe 2c is located on both sides of the straight pipe 2b and the water pumping pipe 2a, and a water inlet pipe 4a located in the middle and a symmetrically arranged injection pipe 4c on both sides are provided below the cover plate 2, and an air inlet pipe 4b is provided between the injection pipe 4c and the water inlet pipe 4a, and the air inlet pipe 4b A nozzle 4d is provided between the water inlet pipe 4a, and the nozzle 4d includes a connecting short pipe 4d1 and a nozzle 4.

[0027] In summary, the present application places the pesticide mixer in a container with liquid, and allows the liquid to pass through the filter screen 1a and the plurality of filter holes 1b on the base 1 into the filter chamber 5 formed by the cover plate 2, the filter screen 1a and the base 1, and the liquid in the filter chamber 5 is extracted through the water pump 3 and the suction pipe 2a on the cover plate 2, and pumped into the straight pipe 2b connected to the water inlet pipe 4a, and flows through the water inlet pipe 4a, the nozzle 4d, and the air inlet pipe 4b in turn, and is finally discharged from the downward nozzle 4c1 in the injection pipe 4c to form a larger jet, and the force generated by the jet and the liquid in the container drives the rotation, thereby completing the stirring.
