Description

Technical Field

[0001] The invention relates to the technical field of herbicide preparation, in particular to a herbicide preparation mixing device. Background Art

[0002] During the production process, insecticides are mixed and formulated with multiple agents, and emulsifiable concentrate needs to be added. The emulsifying properties of emulsifiable concentrate can allow the small oil droplets of insecticide dissolved in oil to be evenly dispersed in water to form a stable emulsion. However, during the mixing and stirring process, a large amount of foam and floating objects formed by emulsifiable concentrate will be generated on the surface of the insecticide suspension. Before filling, the floating objects need to be disposed of.

[0003] An existing patent publication numbered CN210543694U describes a floating debris treatment device for insecticide production, comprising a treatment box having a cross frame fixedly connected to the outer wall of the treatment box, two symmetrical chutes formed on the side walls of the treatment box, each of which has a threaded rod rotatably connected thereto, a cavity formed within the cross frame, and both ends of the two threaded rods extending into the cavity and rotatably connected to the inner wall of the cavity, a drive mechanism provided within the cavity, and connected to the two threaded rods, and a pull net provided within the treatment box, and connected to the two threaded rods. Advantages include: This solution allows for more convenient collection and treatment of floating debris using mechanical equipment, saving significant manpower; However, in the actual production process, it is found that floating objects are continuously generated during the mixing process. The above-mentioned net-pulling cleaning method requires repeated operations, which is relatively troublesome. In addition, there is actually a stirring shaft inside the mixing tank, which makes it impossible to form a complete net. The above operation can only be achieved by transferring the liquid medicine to other containers after the mixing is completed. In addition, the floating objects are mostly foamy, and the net-pulling process easily causes the floating objects to leak from the inside of the mesh. The cleaning is not comprehensive and requires multiple cleanings, which increases the overall time cost and equipment cost of the floating object cleaning operation accordingly, which is very troublesome.

DETAILED DESCRIPTION

[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it constitute a separate or selective embodiment that is mutually exclusive with other embodiments.

[0022] Example 1: Reference Figures 1 to 6, which is the first embodiment of the present invention, provides a herbicide preparation and mixing device, comprising a mixing barrel 100, the bottom surface of which is connected to a driving mechanism 500 via a driving motor, a rotating mechanism 600 being provided in the middle of the driving mechanism 500, an expansion mechanism 400 being provided at the upper end of the driving mechanism 500, the rotating mechanism 600 being connected to a one-way damping bearing 505 of the driving mechanism 500 via a rotating joint 603, an electric telescopic rod 503 being provided in the middle of the one-way damping bearing 505, the lower end of the electric telescopic rod 503 being connected to the output end of the motor, and the upper end being connected to the screw rod 401 of the expansion mechanism 400; A sliding rod 402 is provided at the upper end of the screw rod 401, and a sliding joint 405 is slidably provided on the sliding rod 402. The upper end of the sliding joint 405 is connected to the edge of the soft film 300 via a connecting block 406. An inflatable membrane 302 is provided inside the soft film 300. The inflatable membrane 302 is inflated and is used to squeeze the foam generated when the herbicide is mixed to the side. A certain volume of herbicide is placed in the mixing barrel 100 for mixing, and the liquid level is level with the bottom of the separation port 101 on the side of the mixing barrel 100. The separation port 101 is connected to a sealing plate 700. A driven gear head 701 is provided on the side of the sealing plate 700. The driven gear head 701 is driven by the driving rack 407 at the end of the slide rod 402 to rotate.

[0023] The upper end of the mixing barrel 100 is provided with a ring array of separation ports 101 on the side surface. The separation ports 101 communicate with the separation chamber 200 outside the mixing barrel 100. The upper end of the mixing barrel 100 is provided with a water spray joint 102 and an injection port 105. The water spray joint 102 is used to supply clean water to the nozzle 103 on the top surface of the upper end of the mixing barrel 100. The inner side surface of the separation ports 101 is provided with a chute 106, which is located between the separation ports 101. An output port 104 is provided on the bottom of the mixing barrel 100 .

[0024] The soft film 300 further includes a bottom film 301 , which is placed on the bottom surface of the inflatable film 302 . The bottom film 301 and the inflatable film 302 have the same shape as the bottom surface of the mixing barrel 100 . The elastic deformation capability of the bottom film 301 is smaller than that of the inflatable film 302 .

[0025] Preferably, the inflatable membrane 302 is provided with a hose and a connector for inflating the interior thereof, which are not shown in the figure.

[0026] Both ends of the screw rod 401 are movably connected to the end heads 409, and a limiting rod 404 is provided between the end heads 409, and the screw rod 401 is placed inside the limiting rod 404; A movable head 410 is provided on the screw rod 401. The lower end of the movable head 410 is connected to the limit head 408. The upper end of the screw rod 401 is connected to the slide rod 402 through the end head 409. The side of the movable head 410 is movably connected to one end of the rocker 403. The other end of the rocker 403 is movably connected to the lower end of the sliding joint 405. The driving rack 407 is placed in the sliding groove 106 .

[0027] Preferably, when the driving head 502 rotates counterclockwise, due to the action of the one-way damping bearing 505, the rotating mechanism 600 does not rotate. At this time, the movable head 410 moves up along the screw rod 401, and at the same time, the other end of the rocker 403 drives the sliding joint 405 to slide along the slide rod 402. During the sliding process of the sliding joint 405, the bottom film 301 is gradually unfolded, but there is a gap between the bottom film 301 between two adjacent sliding joints 405 and the inner wall of the mixing barrel 100. During the upward movement of the bottom film 301, the herbicide above the bottom film 301 will enter the bottom of the soft film 300 from the gap on the side, but the foam will still remain on the upper surface of the inflatable film 302.

[0028] Preferably, when the movable head 410 is placed at the lower end of the screw rod 401 , the sliding joint 405 on the slide rod 402 will be retracted, and the soft film 300 will be slightly folded.

[0029] The driving mechanism 500 includes a column lower housing 501, the upper end of which is movably connected to a column upper housing 506 via a rotary joint 603. The column upper housing 506 is provided with side openings 507 arranged in a circular pattern. Preferably, the width of the side opening 507 can accommodate the thickness of the rocker 403 , that is, the rocker 403 can move within the side opening 507 as the electric telescopic rod 503 moves upward.

[0030] The electric telescopic rod 503 is placed inside the lower shell 501 of the column and the upper shell 506 of the column. The lower end of the electric telescopic rod 503 is connected to the output end of the rotating motor through the drive head 502. A blocking block 504 is provided on the inner side of the bottom surface of the side opening 507. The upper end of the electric telescopic rod 503 passes through the blocking block 504 and the end head 409 and is connected to the screw rod 401.

[0031] Preferably, the blocking block 504 is used to block the upper housing 506 of the column. When the screw rod 401 is lifted by the electric telescopic rod 503, the blocking block 504 can prevent the herbicide from entering the upper housing 506 of the column, causing corrosion of the electric telescopic rod 503 and the one-way damping bearing 505.

[0032] The rotating mechanism 600 includes a rotating joint 603 , and the side surface of the rotating joint 603 is connected to the blade 601 via a crossbeam 602 .

[0033] The upper end of the closing plate 700 is connected to the upper edge of the separation opening 101 through a hinge. When the driving rack 407 moves upward along the sliding groove 106, the driving rack 407 drives the driven gear head 701 to rotate, thereby opening the closing plate 700.

[0034] The electric telescopic rod 503 is used to elevate the expansion mechanism 400 . When the expansion mechanism 400 is elevated to the highest position, the upper end surface of the soft film 300 is flush with the bottom surface of the separation opening 101 .

[0035] A release port 201 is provided at the lower end of the separation chamber 200 ; a mixture of foam and water can be discharged from the release port 201 .

[0036] Preferably, when the rotating mechanism 600 is mixing and stirring the herbicide, the output end of the motor that controls the rotation of the driving head 502 rotates clockwise. During the stirring process, the expanding mechanism 400 and the soft film 300 are below the liquid level.

[0037] When in use, the rated capacity of herbicide is added from the injection port 105 and stirred, and the herbicide submerges the expansion mechanism 400 and the soft film 300. At this time, the state is as follows Figure 2 As shown, at this time, the driving head 502 rotates clockwise to complete the stirring, and the foam generated during the stirring process will remain on the liquid surface. Afterwards, the rotating mechanism 600 stops, the electric telescopic rod 503 extends, and the position of the screw rod 401 is raised to the highest point. At this time, the soft membrane 300 is close to the liquid surface. At the same time, the driving rack 407 drives the driven gear head 701 to open the sealing plate 700; at this time, the driving head 502 rotates counterclockwise, and the movable head 410 moves upward, and the soft membrane 300 is gradually stretched. Afterwards, the inflatable membrane 302 is inflated, the inflatable membrane 302 expands, and the soft membrane 300 is completely stretched. The soft membrane 300 just blocks the liquid surface and squeezes the foam at the same time. Finally, the nozzle 103 is used to spray clean water to impact the foam, and the foam will enter the separation chamber 200 along the water flow.

[0038] In summary, after the device completes stirring the herbicide, the soft membrane 300 at the upper end of the expansion mechanism 400 is raised to the liquid surface through the electric telescopic rod 503, and then the inflatable membrane 302 is inflated. The expansion of the inflatable membrane 302 is used to squeeze the foam on the herbicide liquid surface. The foam will be squeezed to both sides of the inflatable membrane 302. At this time, the inflatable membrane 302 will have a certain blocking effect on the herbicide on the bottom surface. Then, the nozzle 103 is used to output clean water, and the clean water is used to flush the foam on both sides of the inflatable membrane 302 into the separation chamber 200. At the same time, the herbicide capacity is not lost to a great extent.
