Description

Technical Field

[0001] The utility model relates to the technical field of screening devices, in particular to a compound herbicide screening device for screening impurities. Background Art

[0002] As the main raw material of herbicides, the processing of sulfentrazone is relatively complex and rigorous. Using dichloroaniline as the starting material, the intermediate substituted phenylhydrazine is obtained through a diazotization reduction reaction, which is the key first step. Then, it undergoes a condensation reaction with acetaldehyde, sodium cyanate and sodium hypochlorite to generate substituted triazolinone, which further constructs the structure of the molecule. It then reacts with monochlorodifluoromethane, and then undergoes a series of reactions such as nitration, reduction, and sulfonamidation to finally produce the target product sulfentrazone.

[0003] After the entire production process is completed, the product needs to be separated, purified and granulated. The heating, drying and granulation process makes the product into granules for easy use and storage. It is particularly important to separate the granules after cooling. This is because it is necessary to ensure that the final sulfentrazone raw material granules have a uniform size and avoid shriveled or too small granules. These unqualified granules may affect the use effect and performance of the herbicide.

[0004] With the help of the screening device, the particles that meet the requirements can be effectively screened out and the parts that do not meet the specifications can be removed. The screening device distinguishes according to the size of the particles, ensuring the consistency and quality of the product. The raw material particles of sulfentrazone produced in this way can better play the weed control effect in practical applications and improve the accuracy and effect of pesticide application. For example, in agricultural production, particles of uniform size can be more evenly distributed in the farmland, better cover the weed growth area, and achieve the ideal weed control effect. At the same time, high-quality particles also help to extend the shelf life and stability of the product.

[0005] Therefore, we proposed a compound herbicide screening device for impurity screening to solve the above problems. Utility Model Content

A screening bucket 9 is dynamically connected, a screening plate 10 is provided inside the screening bucket 9, one end of the screening bucket 9 is connected to an inclined discharge plate 11, a pulley 12 is provided on the frame 1, the pulley 12 is slidably connected to the screening bucket 9, an L-shaped block 13 is fixedly connected to the side wall of the frame 1, an inclined discharge plate 14 is also fixed on the frame 1 below the screening bucket 9, a spring column 15 is fixedly connected to the bottom of the frame 1, a mounting frame 16 is fixedly connected to the bottom end of the spring column 15, and a vibration motor 17 is also fixedly installed on the frame 1;

[0025] Frame 1: Serves as the supporting structure of the entire device and provides a mounting base for other components;

[0026] Driving motor 2: provides power source and drives the small wheel disc 3 to rotate through its output end;

[0027] The small wheel 3, the belt 4 and the large wheel 5 constitute a transmission mechanism to transmit the power of the driving motor 2 to the large wheel 5.

[0028] Large wheel disc 5 and bearing seat 6: The large wheel disc 5 rotates stably under the support of the bearing seat 6, and the shaft at its axis drives the eccentric disc 7 to rotate.

[0029] Eccentric disk 7 and connecting rod 8: The rotation of the eccentric disk 7 is converted into the reciprocating motion of the screening bucket 9 through the connecting rod 8 to realize the screening action.

[0030] Screening bucket 9 and screening plate 10: Screening bucket 9 is used to contain materials, and the screening holes on the screening plate 10 are used to screen the materials, leaving the materials that meet the specifications on the screening plate 10, and impurities and the like fall through the screening holes.

[0031] Discharge plate 11: It is convenient for discharging qualified materials after screening.

[0032] Pulley 12: cooperates with the screening bucket 9 to guide and reduce friction, making the movement of the screening bucket 9 smoother.

[0033] L-shaped block 13 is slidably connected with the screening bucket 9 to further ensure the stability of the movement of the screening bucket 9.

[0034] The pouring plate 14 is used to receive impurities and the like dropped from the screening plate 10 .

[0036] Vibration motor 17: assists in increasing the vibration effect of the screening bucket 9 and improves the screening efficiency.

[0037] The screening device achieves effective screening of compound herbicides through ingenious mechanical structure design, and its advantages include: relatively compact structure, stable and reliable power transmission, good screening effect, and adaptability to production needs of different scales. By adjusting parameters such as the size of the screening holes of the screening plate 10, it can flexibly adapt to the screening requirements of different materials;

[0038] The materials can be added through the bucket elevator. After the driving motor 2 is started, the small wheel disc 3 is driven to rotate, and the large wheel disc 5 is driven to rotate through the belt 4, thereby driving the shaft and the eccentric disc 7 to rotate. The rotation of the eccentric disc 7 causes the connecting rod 8 to drive the screening bucket 9 to reciprocate on the frame 1. At the same time, the vibration motor 17 also generates vibration. The materials are added to the screening bucket 9. Under the reciprocating motion and vibration of the screening bucket 9, the materials are constantly rolling and shaking on the screening plate 10. The materials that meet the size of the screening holes are left on the screening plate 10 and discharged along the discharge plate 11, while the smaller impurities pass through the screening holes and fall onto the inclined pouring plate 14. The pulley 12 plays a role in guiding and reducing friction, the L-shaped block 13 further ensures the stability of the movement of the screening bucket 9, and the spring column 15 plays a shock-absorbing and buffering role to ensure the smooth operation of the entire device.

[0039] like Figure 2As shown, in some embodiments, the bearing seats 6 are distributed at both ends of the shaft, and the bearing seats 6 are fixedly mounted on the frame 1. The bearing seats 6 are distributed at both ends of the shaft. This design can provide stable support for the shaft, ensure that the shaft remains balanced and stable during rotation, and reduce the possibility of shaking and deflection. At the same time, the bearing seats 6 are fixedly mounted on the frame 1, so that the entire transmission structure is closely combined with the frame 1, ensuring the integrity and stability of the entire screening device.

[0040] like Figure 2 As shown, in some embodiments, the sieve plate 10 is tilted inside the screening bucket 9, and the sieve plate 10 is provided with screening holes. The tilted design is conducive to the flow and dispersion of materials in the screening bucket 9, so that the materials can be more fully in contact with the screening holes, thereby improving the screening efficiency. Secondly, this tilted structure helps qualified materials move along the tilted direction and eventually be discharged from the discharge plate 11, thereby achieving effective separation and collection of materials.

[0041] like Figure 3 As shown, in some embodiments, a groove is provided on the side wall of the screening bucket 9, and the L-shaped block 13 is slidably connected to the screening bucket 9 through the groove, which can effectively limit the freedom of the screening bucket 9 during the movement so that it can only reciprocate in a specific direction, thereby ensuring the accuracy and stability of the screening action.

[0042] like Figure 3 As shown, in some embodiments, fixing ears for installation are fixed on both sides of the mounting frame 16. The fixing ears are mainly used to facilitate the fixing and installation of the entire device. By providing fixing ears on both sides of the mounting frame 16, it can be firmly fixed to a desired position or foundation using fasteners such as bolts and screws.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
