Technical Field

[0001] The utility model relates to the technical field of compound fertilizer processing, in particular to a vibration screening device for compound fertilizer production. Background Art

[0002] Compound fertilizer is a kind of fertilizer mixed with multiple nutrients. It is usually composed of major nutrients such as nitrogen, phosphorus, potassium and trace elements to meet the various nutritional needs of crop growth. The formula of compound fertilizer can be adjusted according to the needs of different crops to provide the most suitable nutritional combination for crop growth. Its advantages include balanced nutrition, easy use, stable fertilization effect, etc. In order to ensure uniform fertilization, a vibrating screening device is required to separate large and small particles during the processing. The authorization announcement number is CN220532166U Chinese utility model patent A screening device for compound fertilizer processing is disclosed, comprising a first motor, a screw rod is fixedly connected to the driving end of the first motor, a column sleeve is slidably connected to the outer wall of the screw rod, a support seat is fixedly connected to the bottom end of the column sleeve, a multiple screening discharge pipe is fixedly connected to the right side of the top of the column sleeve, a feed port is fixedly connected to the bottom of the multiple screening discharge pipe, a screening box is fixedly connected to the right side of the bottom of the column sleeve, a valve is rotatably connected to the left side of the connecting pipe, and a primary discharge pipe is fixedly connected to the middle of the connecting pipe. In the utility model, the right side of the screen plate is driven by a vibrator to continuously vibrate up and down, and the fertilizer is bounced up by the limit vibration of the spring, which is conducive to the small particle fertilizer passing through the screen plate and continuing to fall, thereby improving the screening efficiency. However, the screening box of the prior art vibrating screening device is often screened by up and down vibration. On the one hand, it is easy to accumulate on the screen plate when loading, which will cause the screen plate to bear large gravity locally and vibrate laboriously. On the other hand, the up and down vibration cannot fully utilize the area of ​​the screen plate, resulting in low screening efficiency and poor screening effect. Utility Model Content

After the screening box moves in the opposite direction, the spring returns to its original state and then compresses the spring in the opposite direction, driving the screening box to vibrate rapidly left and right. There are multiple springs and they are symmetrical on the left and right to ensure that the force on both sides of the screening box is uniform and it slides smoothly without jamming.

[0009] The utility model is further configured as follows: two parallel sliding bars are arranged on the support plate, a sliding groove is arranged at the bottom of the screening box, and the sliding groove is slidably connected with the sliding bar.

[0010] By adopting the above technical solution, the screening box is slidably connected to the support plate through the sliding groove at the bottom and the two sliding rods on the support plate, which has the effect of keeping the screening box stable when vibrating.

[0011] The utility model is further configured to include a drive motor, which is used to drive the turntable to rotate.

[0012] The utility model is further configured as follows: the driving motor is fixed on the fixing plate.

[0013] By adopting the above technical solution, the driving motor drives the turntable to rotate, and only one driving motor is needed to realize the reciprocating movement of the moving frame, and the structure is simple.

[0014] The utility model is further configured as follows: a round hole is opened in the middle of the fixing plate, and the rotating disk is rotatably connected in the round hole.

[0015] By adopting the above technical solution, the turntable is rotatably connected to the circular hole of the fixed plate, thereby realizing the rotatable connection between the turntable and the fixed plate.

[0016] The utility model is further configured as follows: a feed hopper is provided on the top of the screening box, and the feed hopper is communicated with the screening box.

[0017] By adopting the above technical solution, the feed hopper is connected to the screening box, which facilitates feeding into the screening box.

[0018] The utility model is further configured as follows: a discharge port is provided at the abutment point between the screening box and the bottom of the screening plate.

[0019] The utility model is further configured as follows: a material collection box is provided below the discharge port.

[0020] By adopting the above technical scheme, the screened compound fertilizer automatically rolls to the discharge port, falls from the discharge port into the collection box and is collected, realizing automatic unloading and collection, which has the advantage of further improving the screening efficiency.

[0021] The beneficial effects of the utility model are as follows: a turntable is set to drive the fixed lever to rotate, and when the fixed lever rotates, the upper and lower racks are repeatedly and alternately moved, thereby driving the moving frame to move back and forth left and right. Due to the influence of its own inertia, the moving frame will vibrate left and right, so that the screening box can vibrate back and forth left and right along the support plate, and the compound fertilizer can be moved left and right on the screening plate for screening, which has the advantages of quickly spreading the compound fertilizer on the screening plate, making the screening plate evenly stressed, reducing the local stress on the screening plate during vibration, and making full use of the area of ​​the screening plate and improving the screening efficiency; two screening plates are arranged to be inclined and in opposite directions, and the screened compound fertilizer automatically rolls off the screening plate under the influence of its own gravity, which is convenient for unloading and can further improve the screening efficiency.
