Description

Technical Field

[0001] This utility model relates to the field of fertilizer raw material screening technology, and in particular to a raw material screening device for fertilizer processing. Background Technology

[0002] In the production and processing of fertilizers, it is necessary to mix a variety of raw materials, including organic waste, straw, human, animal and poultry manure, oilseed cake, agricultural by-products and solid waste from food processing. Straw-based raw materials need to be screened before use to remove soil and stones trapped inside the straw.

[0003] Most existing screening methods rely on manual patting and shaking to remove soil and stones adhering to straw leaves, resulting in low screening efficiency and high labor intensity. Utility Model Content

[0004] The purpose of this invention is to provide a raw material screening device for fertilizer processing that can efficiently remove soil and stones adsorbed on straw leaves, replacing manual shaking and achieving high screening efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A raw material screening device for fertilizer processing includes a support base. Two upper supports are fixedly connected to the outer surface of the support base. The upper surface of each upper support has a mounting hole, and a cylinder is fixedly installed inside the mounting hole. A linkage seat is fixedly connected to the telescopic end of the cylinder. Multiple elastic steel bars are fixedly connected between the two linkage seats. Two sliding holes are provided on the upper surface of the upper support, and a limit slide rod is slidably connected inside the sliding hole. One end of the limit slide rod is fixedly connected to the upper surface of the linkage seat.

[0007] By adopting the above technical solution, the conveyed straw can be effectively beat, and the soil and stones adhering to the straw leaves can be effectively removed.

[0008] Furthermore, multiple conveying rollers are rotatably mounted on the inner side of the support base, and a conveyor belt is sleeved on the outside of the multiple conveying rollers. Multiple through holes are provided on the outer surface of the conveyor belt.

[0009] By adopting the above technical solution, straw can be transported using a conveyor belt, while the through holes on the conveyor belt can be used to ensure the effective transport of soil and rocks.

[0010] Furthermore, the inner bottom end of the support base is fixedly connected to an inclined first discharge trough, and the discharge end of the first discharge trough is located outside the support base.

[0011] By adopting the above technical solution, the detached soil and rocks can be easily discharged along the first discharge chute.

[0012] Furthermore, multiple pressure rollers are rotatably mounted on one end of the support base, and the pressure rollers are attached to the outer surface of the conveyor belt.

[0013] By adopting the above technical solution, it is possible to effectively ensure that the straw is cut stably.

[0014] Furthermore, one end of the support base is rotatably connected to two cutting rollers, which are arranged side by side and located at the unloading end of the conveyor belt.

[0015] By adopting the above technical solution, a cutting roller can be used to crush straw-like raw materials.

[0016] Furthermore, a transmission gear is fixedly installed at one end of the shaft of the cutting roller, and the two transmission gears are meshed together. A motor is fixedly installed on the side surface of the support base, and the rotating shaft of the motor is fixedly connected to the rotating shaft of one of the cutting rollers.

[0017] By adopting the above technical solution, it is ensured that the two cutting rollers can rotate synchronously in opposite directions.

[0018] In summary, the beneficial technical effects of this utility model are as follows:

[0019] 1. This utility model can activate a cylinder when conveying straw-like raw materials. The reciprocating extension and retraction of the cylinder can effectively drive the linkage seat to reciprocate. With the reciprocating motion of the linkage seat, multiple elastic steel bars fixedly connected between the two linkage seats can rhythmically strike the conveyed straw. This can effectively shake out the soil and stones trapped inside the straw, effectively screen the straw-like raw materials, and effectively improve its practicality. It can also effectively remove the soil and stones adhering to the straw leaves.

[0020] 2. When conveying straw raw materials, this utility model starts the motor. Under the linkage of two transmission gears, the rotation of the motor can effectively drive the two cutting rollers to rotate synchronously in opposite directions, thereby enabling the cutting operation of straw raw materials passing between the two cutting rollers, and the overall functionality is effectively improved.

[0024] The method of this utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Reference Figure 1 , Figure 2 A raw material screening device for fertilizer processing includes a support base 1. Two upper supports 4 are fixedly connected to the outer surface of the support base 1. Mounting holes are provided on the upper surface of the upper supports 4, and cylinders 5 are fixedly installed inside the mounting holes. Linkage seats 13 are fixedly connected to the telescopic ends of the cylinders 5. Multiple elastic steel bars 7 are fixedly connected between the two linkage seats 13. Two sliding holes are provided on the upper surface of the upper supports 4, and limiting rods 6 are slidably connected inside the sliding holes. One end of the limiting rod 6 is fixedly connected to the upper surface of the linkage seats 13. When conveying straw-like raw materials, cylinder 5 is activated. The reciprocating extension and retraction of cylinder 5 effectively drives the linkage seat 13 to reciprocate. With the reciprocating motion of the linkage seat 13, multiple elastic steel bars 7 fixedly connected between the two linkage seats 13 can rhythmically strike the conveyed straw. This can effectively shake out the soil and stones trapped inside the straw, effectively screen the straw-like raw materials, and effectively improve its practicality. It can also effectively remove the soil and stones adhering to the straw leaves.

[0026] Reference Figure 1 Multiple conveying rollers are rotatably mounted on the inner side of the support base 1, and a conveyor belt 2 is sleeved on the outside of the multiple conveying rollers. Multiple through holes are provided on the outer surface of the conveyor belt 2. An inclined first discharge trough 3 is fixedly connected to the inner bottom of the support base 1. The discharge end of the first discharge trough 3 is located outside the support base 1. The conveyor belt 2 can be used to transport the straw to be processed. At the same time, the through holes on the outer surface of the conveyor belt 2 are used to ensure that the fallen soil and stones can fall into the interior of the first discharge trough 3 and roll down the first discharge trough 3 to the designated position.

[0027] Reference Figure 1 , Figure 2Multiple pressure rollers 8 are rotatably mounted on one end of the support base 1. The pressure rollers 8 are attached to the outer surface of the conveyor belt 2. Two cutting rollers 9 are rotatably connected to one end of the support base 1. The two cutting rollers 9 are arranged side by side and located at the feeding end of the conveyor belt 2. A transmission gear 12 is fixedly mounted on one end of the rotating shaft of the cutting roller 9. The two transmission gears 12 are meshed and connected. A motor 11 is fixedly mounted on the side surface of the support base 1. The rotating shaft of the motor 11 is fixedly connected to the rotating shaft of one of the cutting rollers 9. A second discharge trough 10 is provided at one end of the support base 1. When conveying straw raw materials, the motor 11 is started. Under the linkage of the two transmission gears 12, the rotation of the motor 11 can effectively drive the two cutting rollers 9 to rotate synchronously in opposite directions, thereby enabling the cutting operation of straw raw materials passing between the two cutting rollers 9. The overall functionality is effectively improved.

[0028] Working principle: In use, the device is first installed at the designated location, and then the straw material to be processed is placed on the conveyor belt 2. Then, the conveyor belt 2 is rotated so that the straw material can pass through the elastic steel bars 7 in an orderly manner. At this time, the cylinder 5 is started. The reciprocating extension and retraction of the cylinder 5 can effectively drive the linkage seat 13 to reciprocate. With the reciprocating movement of the linkage seat 13, the multiple elastic steel bars 7 fixedly connected between the two linkage seats 13 can rhythmically beat the conveyed straw. The fallen soil and stones can pass through the through holes on the outer surface of the conveyor belt 2 and fall into the interior of the first discharge trough 3. Then, as the first discharge trough 3 discharges to the designated location, as the straw is continuously conveyed, the pressure roller 8 can limit and compact the output straw. Then, the motor 11 is started. Under the linkage of the two transmission gears 12, the rotation of the motor 11 can effectively drive the two cutting rollers 9 to rotate synchronously in opposite directions, thereby cutting the straw material passing between the two cutting rollers 9. The cut straw falls on the second discharge trough 10 and is discharged.
