Description

Technical Field

[0001] The utility model relates to the technical field of humic acid fertilizer sieving devices, and more specifically, to a humic acid fertilizer sieving device. Background Art

[0002] In the existing humic acid fertilizer screening technology, due to the non-uniform size of humic acid fertilizer particles, some inconvenience may be caused during use. The size of humic acid fertilizer particles directly affects its dissolution rate in the soil and the absorption efficiency of plants. If the particles are too large, the dissolution rate of the fertilizer in the soil may slow down, affecting the immediate absorption of the plants; if the particles are too small, the fertilizer may dissolve quickly in the soil, but the duration is short, affecting the durability of the fertilizer effect. Therefore, the non-uniformity of particle size will affect the normal use of humic acid fertilizers and reduce their fertilizer efficiency.

[0003] In addition, the existing humic acid fertilizer screening device usually adopts a fixed structure. After the screening is completed, the unloading process of this structure may not be convenient. The fixed structure means that the position of the screening device is fixed, which may result in the need to manually remove the screened fertilizer from the screen after the screening is completed. Such operation not only increases the labor intensity, but also may reduce production efficiency.

[0004] In addition, the existing screening device usually uses a filter plate for filtering when processing waste. The function of the filter plate is to prevent larger particles from passing through and allow humic acid fertilizers to pass through. However, the installation and disassembly process of the filter plate in the prior art is often cumbersome, which brings inconvenience to replacing filter plates of different models according to actual needs. In the actual production process, it may be necessary to replace filter plates of different pore sizes according to the type and particle size requirements of the humic acid fertilizer. If the installation and disassembly process of the filter plate is complicated, the time for replacing the filter plate will be extended, affecting the production progress. Utility Model Content

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides a humic acid fertilizer screening device, which has the following beneficial effects:

[0018] 1. The screening device realizes the separation of humic acid fertilizer particles through the combined design of filter plates, filter bins, movable plates and collection bins. The detachable installation of the filter plates and the movable installation of the filter bins make the screening process more flexible and efficient. The setting of the movable plate, motor and connecting rod provides additional power. Through the linkage of the rotating plate and the connecting rod, the filter bin swings on the support rod, thereby improving the screening efficiency. This design helps to improve the uniformity of humic acid fertilizer particles, ensure its normal use and reduce adverse effects.

[0019] 2. The unloading device realizes the tilting and unloading operation of the collecting bin through the coordinated design of components such as hydraulic cylinders, hydraulic rods and connecting seats. The drive of the hydraulic cylinder and the connection of the hydraulic rod enable the movable plate to rotate on the base, thereby driving the collecting bin and the filtering bin to tilt. The opening and closing control of the valve enables the fertilizer in the collecting bin to be discharged smoothly through the discharge pipe, while the fertilizer in the filtering bin can fall into another peripheral collection device. This design simplifies the unloading process and improves production efficiency and operational convenience.

[0020] 3. The quick-change device realizes the rapid replacement of the filter plate through the combined design of the rotating sleeve, the sliding sleeve, the lead screw, the fixed sleeve, the fixed rod, the matching frame, the clamping mechanism and the matching groove. The rotation of the rotating sleeve and the meshing of the inner gear and the outer gear drive the lead screw to rotate, and then the sliding sleeve slides, thereby driving the matching groove to move, realizing the outward movement of the matching frame, so that the clamping frame is disengaged from the clamping groove, the removal of the fixed sleeve and the removal of the filter plate make the replacement of the filter plate faster and easier. This design improves production efficiency and flexibility, makes it more convenient to replace filter plates of different models according to needs, and reduces cumbersome operations and time consumption.
