Description

Technical Field

[0001] This utility model relates to the field of dilution mixing tank technology, and in particular to a non-slip, hand-held pesticide dilution mixing tank for farmland. Background Technology

[0002] In agricultural production, pesticide dilution is an important part of field management. Farmers need to mix solid or liquid pesticides with water in a specific ratio before spraying to achieve the effect of preventing and controlling pests and diseases.

[0003] Currently, most commonly used pesticide dilution tools for farmland are ordinary plastic buckets. These buckets have shortcomings in actual use: the handles are mostly simple plastic handles with smooth surfaces. When farmers operate in the field, their hands are easily contaminated with pesticide residues or sweat, causing the handles to slip. This not only affects the ease of carrying, but may also cause pesticide leakage due to the bucket falling off, posing a safety hazard.

[0004] Solid pesticides are prone to clumping during storage due to factors such as moisture. Ordinary dilution containers lack a dedicated grinding structure, making it difficult for clumped pesticides to dissolve quickly when added directly to the container. This can lead to uneven mixing, affecting the efficacy of the pesticide and potentially clogging the nozzles of subsequent spraying equipment. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-slip, hand-held pesticide dilution mixing bucket for farmland.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A non-slip, hand-held pesticide dilution mixing tank for farmland, comprising a hollow storage tank, a handle ring fixedly connected to the upper part of the outer peripheral wall of the storage tank for carrying, an anti-slip rubber sleeve on the outer surface of the handle ring, a detachable support frame inside the storage tank, a grinding screen for holding agglomerated pesticide placed horizontally inside the support frame, grooves at both ends of the support frame along its length, a rotating plate rotatably connected to the grooves via a horizontally set shaft, a torsion spring sleeved on the outer surface of the shaft, one end of the torsion spring fixedly connected to the outer surface of the shaft, and the other end fixedly connected to the inner surface of the rotating plate, the two ends of the support frame resting on the edge of the storage tank opening via the rotating plates to prevent the support frame from descending along the height direction of the storage tank to the bottom of the storage tank, insertion interfaces on both sides of the support frame along its width, a stirring device for stirring pesticide detachably installed on the support frame, and a grinding device for grinding large agglomerated pesticide particles connected vertically at the bottom of the stirring device.

[0007] Preferably, the mixing device includes a horizontally arranged square plate, with connecting components for mounting the square plate on a support frame at both ends along its length.

[0008] Preferably, the connecting component includes a perforated U-shaped block. Both ends of the square plate are fixedly connected to the perforated U-shaped block. The perforated U-shaped block slides along the width direction of the support frame on the outer surface of the support frame. A buckle block is movably inserted through the perforated U-shaped block. The buckle block is inserted into the insertion interface to fix the position of the perforated U-shaped block on the support frame. A first spring is sleeved on the outer surface of the buckle block. One end of the first spring is fixedly connected to the outer peripheral wall of the buckle block, and the other end is fixedly connected to the outer surface of the perforated U-shaped block.

[0009] Preferably, the square plate has a sliding cavity vertically formed inside, and a sleeve is slidably connected to the inner wall of the sliding cavity. Multiple limiting interfaces are spaced apart on the outer peripheral wall of the sleeve along its height direction. A sliding groove communicating with the sliding cavity is formed on the outer surface of the square plate horizontally. A pin is slidably connected to the inner wall of the sliding groove. The end of the pin away from the sliding groove is inserted into the limiting interface to control the sliding distance of the sleeve on the inner wall of the square plate. A second spring is fixedly connected between the pin and the side opposite to the sliding groove. The second spring is set along the sliding direction of the pin.

[0010] Preferably, the sleeve is rotatably connected to a rotating shaft in the vertical direction inside, and the top of the rotating shaft extends out of the sleeve and is fixedly connected to a handle for hand rotation.

[0011] Preferably, a connecting block is fixedly provided in the middle of the bottom wall of the grinding screen, and a number of holes are evenly opened on the grinding screen for the pesticide particles to pass through after grinding. The holes penetrate the screen body along the thickness direction of the grinding screen.

[0012] Preferably, the grinding device includes a vertically arranged connecting pipe, with inserted rods fixedly connected to both ends of the connecting pipe along its length. One inserted rod is inserted into the inner wall at the bottom of the rotating shaft along the vertical direction, and the other inserted rod is inserted into the inner wall at the top of the connecting block of the grinding screen along the vertical direction to achieve a detachable connection between the connecting pipe and the rotating shaft and the connecting block.

[0013] Preferably, an assembly plate for stirring pesticides is fitted horizontally on the outer surface of the connecting pipe. Corresponding holes are formed on both the assembly plate and the outer peripheral wall of the connecting pipe. Pins are inserted into these holes to control the relative fixation of the assembly plate and the connecting pipe. A connecting rope is fixedly connected to one end of the pin, and the end of the connecting rope away from the pin is fixedly connected to the outer surface of the assembly plate. When pesticides need to be applied in the field, a portion of liquid pesticide and water is first poured into the storage tank through the opening. Then, the support frame is placed into the storage tank from the opening. During the descent of the support frame, the flipping plate is squeezed by the edge of the storage tank opening and rotates horizontally around the shaft. When the support frame descends to a preset position, the flipping plate resets under the force of the torsion spring and rests on the edge of the storage tank opening to position the support frame. The grinding screen is placed horizontally inside the support frame, and the perforated U-shaped block is secured to the top of the support frame along its width. The buckle block is pressed to compress the first spring. After aligning the holes of the U-shaped block with the insertion interface of the support frame, release the buckle block. Under the action of the first spring, the buckle block passes through the U-shaped block and inserts into the insertion interface to fix the square plate to the support frame. Insert the plugs at both ends of the connecting pipe vertically into the bottom of the sleeve and the top of the connecting block to connect the connecting pipe with the rotating shaft and the connecting block. Slide the assembly plate horizontally onto the outer surface of the connecting pipe so that the holes of the assembly plate are aligned with the holes of the connecting pipe. Insert the pin through the hole to fix the assembly plate. Place the clumped solid pesticide in the grinding screen. Turn the handle by hand. The handle drives the rotating shaft to rotate vertically. The rotating shaft drives the grinding block to rotate synchronously through the connecting pipe. The grinding block grinds and crushes the clumped pesticide in the grinding screen. The crushed pesticide particles fall vertically into the storage tank through the drain hole. At the same time, the connecting pipe drives the assembly plate to rotate horizontally. The assembly plate stirs the pesticide and water in the storage tank to mix the pesticide.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, a non-slip rubber sleeve with a textured surface is fitted onto the outer surface of the handle, which effectively increases the friction between the hand and the handle. Even if the hand is contaminated with pesticide residue or sweat, the bucket will not slip and fall off during handling, thus improving the safety and convenience of carrying and solving the problem of slippery handles on existing ordinary dilution buckets.

[0015] In this invention, by utilizing the grinding screen and grinding device inside the support frame, agglomerated solid pesticides can be specifically ground and pulverized. The pulverized pesticide particles can quickly fall into the storage tank through the holes of the grinding screen, fully contact and dissolve with water, avoiding uneven mixing caused by pesticide agglomeration, ensuring the normal efficacy of pesticides, and preventing agglomerated particles from clogging the spraying equipment, thus reducing the risk of equipment failure.

[0016] In this invention, the mixing device and the grinding device share the same power transmission structure. The pesticide grinding and mixing can be achieved simultaneously by turning the handle by hand, without the need for external tools. This simplifies the operation process and avoids secondary pollution caused by external tools, thereby improving the pesticide dilution efficiency and mixing uniformity, and meeting the farmers' needs for efficient dilution.

[0017] In this utility model, the support frame, stirring device, grinding device and other components are all detachable. For example, the support frame is placed on the edge of the liquid storage tank by flipping plate, the stirring device is fixed to the plug interface by buckle block, and the grinding device is plugged in by plug rod. This makes it easy to quickly disassemble each component for thorough cleaning after use, avoid cross-contamination caused by pesticide residues, and the disassembled components are easy to store, reducing the storage space occupied.

[0018] In this invention, the core components such as the liquid storage tank, support frame, and grinding screen are all made of pesticide-resistant materials, which can effectively resist long-term pesticide erosion, slow down the aging rate of components, extend the service life of the entire device, reduce the cost of use for farmers, and are more suitable for long-term and frequent pesticide dilution operations in farmland.

[0021] Example 1, such as Figure 1-5As shown, the non-slip portable pesticide dilution container for farmland includes a hollow storage tank 1. The storage tank 1 is made of hard plastic material resistant to pesticide corrosion to prevent cracking or deformation after long-term contact with pesticides. A carrying ring 3 is fixedly connected to the upper part of the outer peripheral wall of the storage tank 1 for holding. The carrying ring 3 is made of high-strength plastic or metal and is integrally molded with the storage tank 1 by injection molding or bolt fastening. The outer surface of the carrying ring 3 is covered with a non-slip rubber sleeve, which is tightly fitted onto the carrying ring 3 by interference fit and has evenly distributed concave and convex textures on its outer surface. The textured surface increases friction when gripping the container, preventing the handle ring 3 from slipping due to sweaty hands or shaking of the container during carrying. The liquid storage tank 1 has a detachable support frame 2 inside. The support frame 2 is a rectangular frame structure made of metal strips or high-strength plastic strips. Inside the support frame 2, a grinding screen 4 for holding clumps of pesticides is placed horizontally. The grinding screen 4 is made of corrosion-resistant metal or plastic mesh, and its edge rests on the pre-set annular support edge inside the support frame 2, thus ensuring that the grinding screen 4 remains horizontal after placement and will not tilt or fall.

[0022] Rectangular grooves are provided at both ends of the support frame 2 along its length, with the groove openings facing the inner wall of the liquid storage tank 1. A flip plate 22 is rotatably connected to the groove via a horizontally arranged shaft. The shaft is cylindrical and its two ends are fixed to the two side walls of the groove. A circular through hole adapted to the shaft is provided on the flip plate 22, through which the shaft passes, allowing the flip plate 22 to rotate flexibly around the shaft. A torsion spring 23 is fitted on the outer surface of the shaft, with one end of the torsion spring 23 fixedly connected to the outer surface of the shaft and the other end fixedly connected to the inner surface of the flip plate 22. In its natural state, the torsion spring 23 can push the flip plate 22 to open outwards towards the support frame 2. When the support frame 2 is placed into the liquid storage tank 1, the flip plate 22 will first contact the edge of the opening of the liquid storage tank 1 and be squeezed. At this time, the flip plate 22 rotates around the shaft towards the inside of the groove. After the support frame 2 descends to the preset position, the flip plate 22 is released from the squeeze of the opening edge and resets under the elastic force of the torsion spring 23 and rests on the edge of the opening of the liquid storage tank 1, thereby preventing the support frame 2 from continuing to descend along the height direction of the liquid storage tank 1 to the inside of the liquid storage tank 1.

[0023] The support frame 2 has circular insertion interfaces 21 on both sides in the width direction. The two insertion interfaces 21 are symmetrically distributed on both sides of the support frame 2 and their inner diameter is adapted to the outer diameter of the snap-fit ​​block 522 in the subsequent connecting component 52. A stirring device 5 for stirring pesticides is detachably installed on the support frame 2. The stirring device 5 includes a horizontally arranged square plate 51. The square plate 51 is made of a rigid plastic plate or metal plate compatible with the material of the support frame 2. Connecting components 52 for installing the square plate 51 on the support frame 2 are respectively provided at both ends in the length direction of the square plate 51. Each connecting component 52 includes a perforated U-shaped block 521. The perforated U-shaped block 521 has a U-shaped structure with its opening facing the support frame 2. The perforated U-shaped blocks are fixedly connected to both ends of the square plate 51 by welding or injection molding. Block 521, a U-shaped block with a hole 521, can slide along the width direction of the support frame 2 on the outer surface of the support frame 2. The U-shaped block with a hole 521 has a circular hole corresponding to the insertion interface 21, and a latching block 522 is movably inserted into the hole. The latching block 522 has a cylindrical structure with a circular end for easy pressing and a smooth tip at the other end. The latching block 522 fixes the position of the U-shaped block with a hole on the support frame 2 by being inserted into the insertion interface 21. A first spring 523 is sleeved on the outer surface of the latching block 522. One end of the first spring 523 is fixedly connected to a pre-set annular protrusion on the outer peripheral wall of the latching block 522, and the other end is fixedly connected to the outer surface of the U-shaped block with a hole 521. In its natural state, the first spring 523 can push the latching block 522 to maintain its extension. When the U-shaped block 521 with holes is in its extended state, pressing the buckle block 522 compresses the first spring 523, causing the buckle block 522 to retract into the U-shaped block 521. A cylindrical sliding cavity is vertically formed inside the square plate 51. The inner wall of the sliding cavity is polished smooth to reduce sliding resistance. A sleeve 53 is slidably connected to the inner wall of the sliding cavity. The sleeve 53 has a hollow cylindrical structure, and its outer wall fits tightly against the inner wall of the sliding cavity. Multiple circular limiting interfaces 531 are spaced apart along the height of the outer periphery of the sleeve 53. The spacing between each limiting interface 531 is the same, allowing for adjustment of the extension length of the sleeve 53 according to actual usage requirements. A rectangular groove communicating with the sliding cavity is horizontally formed on the outer surface of the square plate 51. A pin 5 is slidably connected to the inner wall of the groove. 4. The pin 54 is a long strip of metal or plastic. The end of the pin 54 away from the slide groove can be inserted into the limiting interface 531 to control the sliding distance of the sleeve 53 on the inner wall of the square plate 51. A second spring 55 is fixedly connected between the side of the pin 54 and the side opposite to the slide groove. The second spring 55 is set along the sliding direction of the pin 54 and can push the pin 54 to keep it inserted into the limiting interface 531 in its natural state. When the pin 54 is pulled, the second spring 55 can be compressed to disengage the pin 54 from the limiting interface 531, thereby adjusting the position of the sleeve 53. A rotating shaft 56 is rotatably connected inside the sleeve 53 in the vertical direction. The rotating shaft 56 is a cylindrical metal shaft or a high-strength plastic shaft, and its outer wall is engaged with the inner wall of the sleeve 53 through a bearing.A rotating shaft 56 has a sleeve 53 extending from its top and is fixedly connected to a handle for manual rotation. The handle is disc-shaped or strip-shaped and is fixed to the rotating shaft 56 by welding or threading. A connecting block 41 is fixedly installed in the middle of the inner bottom wall of the grinding screen 4. The connecting block 41 is cylindrical and has a slot at its top that matches the subsequent insertion rod. Several circular perforations are evenly distributed on the grinding screen 4 for the pesticide particles to pass through after grinding. The perforations penetrate the screen 4 along its thickness direction, and their diameter is adapted to the required size of common pesticide particles after grinding.

[0024] The grinding device 6 includes a vertically arranged connecting pipe 61. The connecting pipe 61 is a hollow cylindrical structure made of a hard material compatible with the material of the rotating shaft 56. Cylindrical inserts are fixedly connected to both ends of the connecting pipe 61 along its length. The two inserts are fixedly connected to both ends of the connecting pipe 61 by welding or injection molding. One insert is vertically engaged with a slot on the bottom inner wall of the rotating shaft 56, and the other insert is vertically engaged with a slot on the top of the connecting block 41 of the grinding screen 4. This engagement method allows for a detachable connection between the connecting pipe 61, the rotating shaft 56, and the connecting block 41. A horizontally mounted assembly plate 62 for mixing pesticides is fitted onto the outer surface of the connecting pipe 61. The assembly plate 62 is a rectangular or circular plate made of corrosion-resistant plastic or metal. The assembly plate 62 and the connecting pipe 61 both have corresponding circular holes on their outer peripheral walls. A pin 65 is inserted into each hole. The pin 65 is cylindrical and is used to fix the assembly plate 62 and the connecting pipe 61. One end of the pin 65 is fixedly connected to a connecting rope 66, which is a wear-resistant nylon rope or metal rope. The end of the connecting rope 66 away from the pin 65 is fixedly connected to the outer surface of the assembly plate 62 to prevent the pin 65 from being lost during use. When pesticides need to be applied to farmland, a portion of liquid pesticide and water is first poured into the storage tank 1 through its opening. Then, the support frame 2 is inserted into the storage tank 1 through its opening. During the descent of the support frame 2, the tilting plate 22 is squeezed by the edge of the storage tank 1 opening and rotates horizontally around the shaft. When the support frame 2 descends to the preset position, the flip plate 22 resets under the elastic force of the torsion spring 23 and rests on the edge of the mouth of the liquid storage tank 1 to position the support frame 2. Then, the grinding screen 4 is placed horizontally inside the support frame 2. Next, the perforated U-shaped block 521 is clamped on the top of the support frame 2 along the width direction of the support frame 2. Press the buckle block 522 to compress the first spring 523. After the hole of the perforated U-shaped block 521 is aligned with the insertion interface 21 of the support frame 2, the buckle block 522 is released. Under the elastic force of the first spring 523, the buckle block 522 passes through the perforated U-shaped block 521 and is inserted into the insertion interface 21 to complete the fixation of the square plate 51 and the support frame 2. Then, the insertion rods at both ends of the connecting pipe 61 are inserted vertically into the bottom of the sleeve pipe 53 and the top of the connecting block 41 to achieve the connection. Connect the pipe 61 to the rotating shaft 56 and the connecting block 41, then fit the assembly plate 62 horizontally onto the outer surface of the connecting pipe 61 so that the holes of the assembly plate 62 are aligned with the holes of the connecting pipe 61. Insert the pin 65 through the hole to fix the assembly plate 62. Finally, place the clumped solid pesticide in the grinding screen 4, turn the handle by hand, and the handle drives the rotating shaft 56 to rotate vertically. The rotating shaft 56 drives the grinding block 63 to rotate synchronously through the connecting pipe 61. The grinding block 63 grinds and crushes the clumped pesticide in the grinding screen 4. The crushed pesticide particles fall vertically into the storage tank 1 through the leakage hole. At the same time, the connecting pipe 61 drives the assembly plate 62 to rotate horizontally. The assembly plate 62 stirs the pesticide and water in the storage tank 1 to achieve pesticide mixing.

[0025] Working principle This non-slip, portable pesticide dilution container for farmland achieves efficient pesticide dilution through the synergistic action of its components. The storage tank 1, as the core storage component, provides space for pesticide and water; its corrosion-resistant material ensures long-term stability. The carrying handle 3, combined with a non-slip rubber sleeve, allows for convenient and non-slip handling, preventing the risk of slipping during transport. The positioning of the support frame 2 relies on the cooperation of the flip plate 22 and the torsion spring 23. When the storage tank 1 is placed inside, the flip plate 22 is squeezed and rotated to smoothly enter. After reaching the preset position, the torsion spring 23 pushes the flip plate 22 back to its original position and rests on the edge of the storage tank 1's opening, limiting the support frame 2's further descent and providing stable support for subsequent component installation. The detachable fixing of the stirring device 5 to the support frame 2 is achieved through the connecting assembly 52. ​​After the perforated U-shaped block 521 engages with the support frame 2, the first spring 523 drives the latching block 522 to insert into the insertion interface 21. The square plate 51 is quickly fixed and easy to disassemble. The length of the sleeve pipe 53 is adjusted by the pin 54 and the second spring 55. Pulling the pin 54 away from the limit interface 531 can adjust the extension length. After releasing, the second spring 55 pushes the pin 54 to reset and lock, so as to adapt to different grinding depth requirements. The power transmission of the grinding device 6 relies on the insertion of the two ends of the connecting pipe 61 with the rotating shaft 56 and the connecting block 41 respectively. When the handle is turned by hand, the rotating shaft 56 is rotated. The rotating shaft 56 transmits power to the grinding block 63 through the connecting pipe 61, so that the grinding block 63 crushes the clumps of pesticide in the grinding screen 4. The crushed particles fall into the storage tank 1 through the leakage hole. At the same time, the connecting pipe 61 drives the assembly plate 62 to rotate synchronously. The assembly plate 62 stirs the pesticide and water in the storage tank 1 to ensure that the two are fully mixed to achieve a precise dilution ratio.
