Description

Technical Field

[0001] The utility model relates to the technical field of pesticide production, in particular to a raw material mixing device for preparing pesticide suspension. Background Art

[0002] Pesticides are chemical agents used in agriculture to control pests and diseases and regulate plant growth. They are widely used in agriculture, forestry, animal husbandry, environmental and household hygiene, pest control and epidemic prevention, and industrial product mildew and moth control. Suspension concentrates (SCs) are solid pesticide technicals uniformly dispersed in water as particles smaller than 4 microns. They feature small particle size, high biological activity, high specific gravity, and compact packaging. Compared to other pesticide formulations, SCs are safer and more environmentally friendly. Therefore, SCs have become the largest-volume pesticide among new water-based formulations. Production of SCs requires a raw material mixing device to mix the solid SCs with water.

[0003] For example, a raw material mixing device for the production of suspension pesticides disclosed in a Chinese patent document (Announcement No.: CN219333992U) can be used to mix solid pesticide and water by rotating the stirring rod through the stirring shaft. The fixed net can break up the granular agent during the rotation, which can improve the mixing effect. The inner wall of the mixing tank can be scraped by the contact between the fixed plate and the bottom of the mixing tank, which can avoid the accumulation of sediment and make the pesticide mixing more uniform. The rotation of the reciprocating screw can realize the moving plate to drive the first motor to move up and down, and the stirring rod, fixed net and fixed plate can be lifted and lowered synchronously during the rotation, which can make the pesticide mixing more powerful and the mixing efficiency higher. At the same time, the fixed plate can lift the pesticide during the rising process, which can well avoid the precipitation of the pesticide.

[0004] However, in actual use, since the stirring shaft has a large resistance when stirring and rotating, when the stirring shaft is lifted and moved by the rotation of the reciprocating screw in conjunction with the movable plate for stirring, the resistance during lifting is large. The large resistance can easily cause the threads of the reciprocating screw and the inner wall of the movable plate to wear out faster, resulting in the need for frequent maintenance and replacement. In addition, after the powder is added, a large amount of powder will float above the liquid surface for a long time, which is easy to form lumps and sink to the bottom of the tank, thereby reducing the mixing efficiency. Utility Model Content

[0027] Example

[0028] like Figure 1-5 As shown, the utility model provides a technical solution: a raw material mixing device for preparing pesticide suspension, comprising a mixing tank body 1, the mixing tank body 1 is divided into a cylinder and a cover body, which are fixed by bolts, so as to be easy to disassemble and clean, and a feed port is provided above the cover body to facilitate the addition of powder, the upper surface of the mixing tank body 1 is fixedly connected with a mounting frame 2, the inner wall of the mounting frame 2 is fixedly mounted with hydraulic cylinders 3 that are symmetrically distributed, the upper surface of the mounting frame 2 is fixedly mounted with a servo motor 4, the output shaft of the servo motor 4 is fixedly mounted with a rotating shaft 5 through a coupling, one end of the rotating shaft 5 passes through the mounting frame 2 and extends to the interior of the mixing tank body 1, the outer surface of the rotating shaft 5 is fixedly connected with symmetrically distributed limiting bars 6, the outer surface of the rotating shaft 5 is movably sleeved with a rotating sleeve 7, and one end of the rotating sleeve 7 passes through and extends to the interior of the mixing tank body 1;

[0029] The outer surface of the rotating sleeve 7 is provided with a lifting and rotating device, and the lifting and rotating device includes a connecting ring 8, and the inner wall of the connecting ring 8 is installed with the outer surface of the rotating sleeve 7 through a bearing.

[0030] The outer surface of the connecting ring 8 is fixedly connected with a symmetrically distributed connecting block 81, the upper surface of the connecting block 81 is fixedly connected to one end of the piston rod of the hydraulic cylinder 3, and the outer surface of the rotating sleeve 7 is provided with a symmetrically distributed guide groove 82. The rotating sleeve 7 is positioned and rotated by the cooperation between the connecting ring 8 and the bearing.

[0031] The inner wall of the guide groove 82 is slidably connected to an arc-shaped slider 83, and the outer surfaces of the two arc-shaped sliders 83 are fixedly connected to the buoyancy ring 84. The inner wall of the buoyancy ring 84 is movably connected to the outer surface of the rotating sleeve 7. The guide groove 82 and the arc-shaped slider 83 cooperate with the buoyancy ring 84 to move up and down.

[0032] The outer surface of the buoyancy ring 84 is provided with mounting grooves 85 distributed in a circular array. The inner walls on both sides of the mounting grooves 85 are hinged with stirring rods 86 through pins. The outer surfaces of the stirring rods 86 are fixedly connected with breaking rods 87 distributed in a circular array. The buoyancy ring 84 moves up and down according to the rise and fall of the liquid level. The breaking rods 87 cooperate with the stirring rods 86 to crush and stir the powder floating above the liquid surface to avoid agglomeration.

[0033] One end of the stirring rod 86 is fixedly connected to a buoyancy ball 88, the outer surface of the rotating sleeve 7 is fixedly connected to stirring blades 89 distributed in a circular array, and the outer surface of the rotating sleeve 7 is fixedly connected to L-shaped driving blocks 810 distributed in a circular array. The buoyancy ball 88 ensures that one end of the stirring rod 86 is always above the liquid surface.

[0034] An extrusion block 811 is movably connected to the inner wall of one end of the L-shaped driving block 810, and a buffer spring 812 is fixedly connected to the upper end of the extrusion block 811. One end of the buffer spring 812 is fixedly connected to the inner top wall of the L-shaped driving block 810. The elastic force of the buffer spring 812 serves to continuously apply extrusion elastic force to the extrusion block 811.

[0035] The lower end of the extrusion block 811 is fixedly connected to a shovel plate 813, and the lower ends of the two shovel plates 813 are in contact with the inner bottom wall of the mixing tank body 1. The lower surface of the mixing tank body 1 is fixedly connected to a discharge pipe 814. The shovel plate 813 serves to scoop up the raw materials settled at the bottom of the mixing tank body 1, thereby facilitating mixing.

[0036] The lifting and rotating device can realize stable lifting and lowering movement during rotation, stirring and mixing, thereby accelerating the mixing of raw materials, and the shovel plate 813 is used to scoop up and mix the materials at the bottom of the mixing tank body 1, thereby avoiding sedimentation when the materials are mixed, and the buoyancy ball 88 is rotated in conjunction with the stirring rod 86 at the liquid surface, thereby breaking up the powder floating above the liquid surface and accelerating the mixing, avoiding agglomeration and sinking to the bottom, thereby improving the efficiency of raw material mixing.

[0037] The working process of this utility model:

[0038] Step 1: Start the servo motor 4. The servo motor 4 drives the rotating sleeve 7 to rotate through the cooperation of the rotating shaft 5 and the limit bar 6. The rotation of the rotating sleeve 7 stirs and mixes the liquid inside the mixing tank body 1 through the stirring blade 89. The cooperation of the buoyancy ring 84 and the buoyancy ball 88 ensures that the stirring rod 86 is always located above the liquid surface. When the powder is added to the mixing tank body 1 through the feed port, part of the powder floats above the liquid surface. At this time, the rotation of the stirring rod 86 stirs the floating powder through the breaking rod 87, so that it quickly merges with the liquid to avoid caking and sinking to the bottom.

[0039] Step 2: Simultaneously start the piston rod of the hydraulic cylinder 3 to perform reciprocating telescopic motion. The reciprocating telescopic motion of the piston rod of the hydraulic cylinder 3 drives the connecting ring 8 to move up and down through the connecting block 81. The lifting and lowering motion of the connecting ring 8 drives the rotating sleeve 7 that is rotating and mixing to perform lifting and lowering motion, thereby achieving lifting and rotating mixing, further improving the mixing efficiency of the raw materials.

[0040] Step three, when the rotating sleeve 7 moves downward, the contraction of the buffer spring 812 and the cooperation of the extrusion block 811 make the shovel plate 813 contact the bottom of the mixing tank body 1, and the raw materials precipitated at the bottom of the mixing tank body 1 are scooped up by the rotation of the shovel plate 813. At this time, the rotating sleeve 7 rotates and rises, and cooperates with the shovel plate 813 to mix the scooped raw materials. The reciprocating lifting and lowering rotation of the rotating sleeve 7 avoids precipitation at the bottom of the mixing tank body 1.

[0041] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
