Abstract
Description
Technical Field
[0001] This application relates to the field of pesticide testing technology, and in particular to equipment for testing the viscosity of liquid pesticides. Background Technology
[0002] Liquid pesticide viscosity testing equipment mainly includes rotational viscometers (which calculate viscosity by measuring the resistance of a rotor rotating in a liquid), capillary viscometers (which estimate viscosity based on the time it takes for the liquid to flow through a capillary), and falling ball viscometers (which determine viscosity based on the speed at which a small ball falls in a liquid). These equipment are used to accurately measure pesticide viscosity to ensure product performance.
[0003] The liquid pesticide viscosity testing equipment uses a motor to drive a rotor to rotate at a constant speed in the liquid pesticide. The rotor generates torque due to the viscous resistance of the liquid and transmits it to the sensor. The sensor converts the torque signal into an electrical signal, and the viscosity value of the liquid pesticide is calculated.
[0004] In existing technologies, some liquid pesticide viscosity testing equipment has many problems in rotor replacement. Traditional equipment rotors often use complex fixing methods such as threaded connections. When replacing rotors according to different pesticide viscosities, the operation is cumbersome, time-consuming, requires tools, and is prone to improper installation, which reduces testing efficiency and affects measurement accuracy due to installation errors. Therefore, a liquid pesticide viscosity testing device is proposed to solve the above problems. Utility Model Content

A fixing ring is fixedly connected to the outside of the drive rod, and multiple T-slots are formed inside the fixing ring. A support rod is detachably connected to the bottom of the drive rod, and a driven groove is formed inside the support rod. Multiple springs are fixedly connected to the bottom inner wall of the driven groove, and a driven ring is fixedly connected to the top of the multiple springs. A connecting ring is fixedly connected to the outside of the driven ring, and multiple connecting columns are rotatably connected to the top of the connecting ring.

Preferably, in the detection mechanism, the top of the drive rod is connected to the motor to receive and transmit power, and the external fixing ring provides stable support. The internal T-slot is used for rotor limiting. The bottom of the drive rod is detachably connected to the support rod to facilitate the replacement of rotors of different specifications.

A gear is rotatably connected to the inner wall of the left side of the fixing box, and a limiting component is connected to the right side. A connecting groove is provided inside. The gear is driven to rotate by a sliding toothed plate, which causes the connecting plate to slide within the connecting groove. The limiting post on the right side of the connecting plate engages with the cable management hole to fix the cable and organize the wiring.
[0009] By adopting the above technical solution, the limiting component includes a linkage column, the left side of which is fixedly connected to the right side of the gear, and the inside of the connecting plate is provided with a slot, and multiple springs are fixedly connected to the left inner wall of the connecting slot. Preferably, in the limiting assembly, the left side of the linkage column is fixed to the gear and rotates with the gear. The connecting plate has a slot for the linkage column to be inserted. The spring on the inner wall of the connecting slot provides elastic restoring force to assist in the adjustment and locking of the belt length.
[0010] By adopting the above technical solution, the bottom of the drive rod and the top of the driven ring are in contact, and the outside of the driven ring is slidably connected to the inside of the spring. Preferably, the bottom of the drive rod is in close contact with the top of the driven ring, and pressure can be applied when installing the rotor. The driven ring is slidably embedded in the spring, and the linkage is achieved by utilizing the elasticity of the spring, ensuring that the rotor is installed stably.
[0011] By adopting the above technical solution, the outer side of the T-shaped block and the inner wall of the T-shaped groove are in contact, and the top of the connecting column and the bottom of the T-shaped block are sleeved on the outside of the connecting shaft; Preferably, the T-block and the T-slot fit tightly together to achieve precise positioning, and the top of the connecting column and the bottom of the T-block are fitted onto the connecting shaft to form a stable rotation structure, ensuring that the rotor runs smoothly during testing.

[0013] By adopting the above technical solution, the outer side of the limiting post is in contact with the inner wall of the beam hole, and the outer side of the linkage post is in contact with the inner wall of the empty groove. Preferably, the limiting post fits tightly with the inner wall of the bundle hole to achieve precise fixation of the bundle, and the linkage post contacts and links with the inner wall of the slot. The opening and closing of the limiting post is controlled by the elastic structure, which facilitates the adjustment of the bundle.
[0014] In summary, this application includes at least one of the following beneficial technical effects: 1. In this utility model, by aligning the support rod with the drive rod, the bottom of the drive rod presses the driven ring, causing the connecting ring to slide down, while simultaneously pressing the spring. The connecting ring, through the connecting column, drives the T-shaped block to pull the connecting shaft to slide in the linkage groove, allowing the T-shaped block to smoothly engage with the T-shaped groove. By removing the T-shaped block, the limitation on the support rod is released. Thus, the quick loading and unloading of the rotor is achieved through the snap-fit structure of the T-shaped block and the T-shaped groove and the spring linkage mechanism, significantly improving the adaptation efficiency under different viscosity testing scenarios and reducing human operation errors. 2. By pressing the lever above the toothed plate, the toothed plate meshes with the gear, which in turn drives the gear to rotate. The gear then drives the linkage column to rotate. When it rotates into the slot, the excess clearance causes the connecting plate to disengage from the bundle hole under the elastic reset action of the second spring. The toothed plate is then released, and the elastic action of the second spring causes the connecting plate to reset, which in turn presses the linkage column to reset. At the same time, the limit column is re-engaged into the bundle hole. This achieves rapid adjustment and locking of the bundle length through the meshing transmission of the toothed plate and gear and the elastic reset mechanism of the spring, significantly improving the efficiency of the wiring arrangement.

[0017] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.
[0018] Example: A liquid pesticide viscosity testing device, referring to... Figures 1 to 3 It includes a housing 1, a motor 2 fixedly connected to the bottom of the housing 1, a detection mechanism 3 fixedly connected to the drive end of the motor 2, and a wire harness mechanism 4 fixedly connected to the right side of the housing 1. The detection mechanism 3 includes a drive rod 301, which provides fixation and support for the fixed ring 302. The top of the drive rod 301 is fixedly connected to the drive end of the motor 2. The drive rod 301 receives force from the motor 2 and rotates, thereby driving the conical rotor 5 to rotate through the support rod 304, thus detecting the viscosity of liquid pesticides. The fixed ring 302 is fixedly connected to the outside of the drive rod 301. The fixed ring 302 provides space for the T-slot 303. Multiple T-slots 303 are opened inside the fixed ring 302. The T-slots 303 are used to cooperate with the T-block 310 to limit and fix the support rod 304. The bottom of the drive rod 301 is detachably connected to the support rod 304. The support rod 304 provides space for the driven groove 305. The driven groove 305 is opened inside the support rod 304, which provides fixation and support for the spring 306. Multiple springs 306 are fixedly connected to the bottom inner wall of the driven groove 305. The springs 306 provide elastic support for the driven ring 307 above. The driven ring 307 is fixedly connected to the top of the multiple springs 306. When the support rod 304 is installed, it is aligned with the drive rod 301 and placed so that the bottom of the drive rod 301 presses against the driven ring 307. A connecting ring 308 is fixedly connected to the outside of the driven ring 307, so that the driven ring 307 can drive the connecting ring 308 to slide down synchronously. Multiple connecting posts 309 are rotatably connected to the top of the connecting ring 308, so that the connecting ring 308 can drive the connecting posts 309 to rotate synchronously.

The support rod 304 provides fixation and support for the connecting blocks 31101. The connecting blocks 31101 have linkage grooves 31102 inside. The linkage grooves 31102 provide limiting and guiding functions for the connecting shaft 31103. The connecting shaft 31103 is slidably connected inside the linkage grooves 31102. When the connecting column 309 rotates, it drives the T-shaped block 310 to rotate around the connecting shaft 31103, while pulling the connecting shaft 31103 to slide, so that the T-shaped block 310 can be smoothly inserted into the T-shaped groove 303, thereby completing the limiting and fixing of the support rod 304. Specifically, the testing mechanism 3 consists of a drive rod 301, a fixed ring 302, a support rod 304, a driven ring 307, a T-block 310, and a linkage assembly 311. The top of the drive rod 301 is connected to the drive end of the motor 2. The outer fixed ring 302 has multiple T-slots 303. The bottom of the support rod 304 is connected to a conical rotor 5. The inner driven groove 305 is equipped with a spring 306 and a driven ring 307. Externally, it is linked with the T-block 310 through the connecting block 31101, the linkage groove 31102, and the connecting shaft 31103 of the linkage assembly 311. During installation, the drive rod 301 squeezes the driven ring 307, causing the connecting ring 308 to slide down, so that the T-block 310 is stuck into the T-slot 303 to complete the limit. After being driven by the motor, the viscosity is detected by rotating the conical rotor 5.
[0019] Reference Figure 2 and Figure 3 , refer to Figure 4 and Figure 5 The wire harness mechanism 4 includes a fixing box 41, which provides installation space for internal components. The left side of the fixing box 41 is fixedly connected to the right side of the housing 1, and the housing 1 provides fixation and support for the fixing box 41. A gear 42 is rotatably connected to the inner wall of the left side of the fixing box 41. The gear 42 meshes with a toothed plate 45, and the gear 42 rotates under the force from the toothed plate 45. A limit assembly 43 is fixedly connected to the right side of the gear 42, and the limit assembly 43 rotates under the force from the gear 42. The inside of the 41 is provided with a connecting groove 44, which provides a limiting and guiding function for the connecting plate 46. The toothed plate 45 is slidably connected inside the fixing box 41. By pressing the toothed plate 45, it can drive the gear 42 to rotate. The connecting plate 46 is slidably connected inside the connecting groove 44, which provides a limiting and guiding function for the connecting plate 46. Two limiting posts 47 are fixedly connected to the right side of the connecting plate 46. The limiting posts 47 are used to snap into the inside of the bundle hole 49, thereby fixing the bundle 48. A strap 48 is rotatably connected to the rear side of the fixing box 41. The strap 48 provides space for the opening of the cable hole 49. Multiple cable holes 49 are opened inside the strap 48. The cable holes 49 are used to cooperate with the limiting post 47 to complete the limiting and fixing of the cable hole 49. The limiting component 43 includes a linkage post 4301. The linkage post 4301 can receive the force from the gear 42 to rotate. The left side of the linkage post 4301 is fixedly connected to the right side of the gear 42. The gear 42 can drive the linkage post 4301 to make a circular motion. The connecting plate 46 has a slot 4302 inside. When the linkage post 4301 rotates into the slot 4302, the extra space is connected to multiple springs 4303 fixedly connected to the left inner wall of the connecting groove 44. This allows the connecting plate 46 to drive the limiting post 47 to disengage from the cable hole 49 through the elastic reset of the springs 4303. The length of the strap 48 can be adjusted according to the circuit. Specifically, the cable harness mechanism 4 consists of a fixed box 41, a gear 42, a toothed plate 45, a connecting plate 46, a cable harness 48, and a limiting component 43. The fixed box 41 is fixed to the right side of the housing 1, and the gear 42 is rotatably connected to the left side inside. The gear meshes with the sliding toothed plate 45. The right side of the gear is connected to the linkage post 4301 in the limiting component. The connecting plate 46 slides through the connecting groove 44, and a limiting post 47 is provided on its right side. The cable harness 48 is rotatably connected to the fixed box on the rear side, and multiple cable holes 49 are opened on the surface to cooperate with the limiting posts.
[0020] Reference Figure 1 , Figure 2 and Figure 4 The outer surface of the T-block 310 contacts the inner wall of the T-slot 303. The T-block 310 is used to engage with the inner wall of the T-slot 303, thereby limiting and fixing the support rod 304. The bottom of the drive rod 301 contacts the top of the driven ring 307. The drive rod 301 can press the top of the driven ring 307, causing it to slide down, thus preparing for subsequent actions. The outer surface of the driven ring 307 is slidably connected to the inside of the spring 306. The spring 306 provides limiting and guiding functions for the driven ring 307. The top of the connecting post 309 and the bottom of the T-block 310 are sleeved on the outside of the connecting shaft 31103. The connecting shaft 31103 provides support for the connecting post 309 and the T-block 310. The bottom of the support rod 304... A conical rotor 5 is fixedly connected to the part, which is used to rotate in the liquid pesticide to test the viscosity. A bracket 6 is provided at the bottom of the housing 1. The bracket 6 provides fixation and support for the support column 7. The support column 7 is fixedly connected to the top of the bracket 6. The support column 7 provides fixation and support for the front housing 1 and can be adjusted by a knob. The outer side of the limiting column 47 contacts the inner wall of the bundle hole 49. The limiting column 47 is used to snap into the inside of the bundle hole 49 to complete the limiting and fixing of the strap 48. The outer side of the linkage column 4301 contacts the inner wall of the empty groove 4302. When the linkage column 4301 rotates to the empty groove 4302, the extra space at this time allows the connecting plate 46 to be elastically reset by the second spring 4303. Specifically, in the testing mechanism, the T-block 310 and the T-slot 303 cooperate to limit the support rod 304, the drive rod 301 squeezes the driven ring 307, and the rotor is installed through the spring 306, connecting column 309, etc., driving the conical rotor 5 to measure viscosity. The bottom bracket 6 and the support column 7 of the equipment can adjust the height to stabilize the shell 1. In terms of the wire harness mechanism, the limiting column 47 and the bundle hole 49 cooperate to fix the bundle 48. When the linkage column 4301 rotates to the empty slot 4302 of the connecting plate 46, the spring 4303 makes the connecting plate elastically reset, completing the adjustment and fixation of the wire harness length.
[0021] The implementation principle of this application embodiment is as follows: When it is necessary to detect the viscosity of liquid pesticides, firstly, according to the viscosity characteristics of the liquid pesticide to be detected, a suitable rotor is selected. By aligning the support rod 304 with the drive rod 301, the bottom of the drive rod 301 presses against the driven ring 307. The driven ring 307 drives the connecting ring 308 to slide down, while simultaneously pressing the spring 306. The connecting ring 308 drives the T-block 310 to rotate around the connecting shaft 31103 through the connecting post 309, and pulls the connecting shaft 31103. 03 Slides within the linkage groove 31102, allowing the T-block 310 to smoothly engage with the T-slot 303, completing the rapid installation and limiting fixation of the rotor. After the motor 2 starts, the drive rod 301 drives the support rod 304 and the conical rotor 5 to rotate in the liquid pesticide. By detecting parameters such as the torque during rotation, the viscosity of the liquid pesticide can be determined. When the rotor needs to be replaced, the T-block 310 is pulled out, releasing the limiting effect on the support rod 304, thereby enabling the rotor to be removed to achieve accurate detection of liquid pesticides with different viscosity ranges.
[0022] When the wiring needs to be organized, pressing the lever above the toothed plate 45 causes the toothed plate 45 to mesh with the gear 42, which in turn drives the gear 42 to rotate. The gear 42 then drives the linkage column 4301 to rotate. When it rotates into the slot 4302, the excess gap causes the connecting plate 46 to move the limiting column 47 away from the bundle hole 49 under the elastic reset action of the second spring 4303. At this time, the bundle belt 48 can be adjusted according to the length of the wiring. After adjustment, the toothed plate 45 is released, and the elastic action of the second spring 4303 causes the connecting plate 46 to reset, which in turn squeezes the linkage column 4301 to reset it. At the same time, the limiting column 47 is re-engaged into the bundle hole 49, thus achieving a secure bundle of wiring and preventing messy wiring from affecting the use of the equipment.
