Description
Technical Field
[0001] The utility model relates to the technical field of fertilizer production, in particular to a reciprocating screening mechanism for fertilizer production. Background Art
[0002] Chemical fertilizers, referred to as fertilizers, are fertilizers made by chemical and / or physical methods that contain one or more nutrients required for the growth of crops. They are also called inorganic fertilizers, including nitrogen fertilizers, phosphorus fertilizers, potassium fertilizers, micro-fertilizers, compound fertilizers, etc., and are not edible. In the process of fertilizer production, separating the size of fertilizer particles is a very important step.
[0003] However, in the prior art, when screening fertilizers, a multi-layer screening structure is mostly used to reciprocate and screen the fertilizer particles. However, the screens inside the existing reciprocating screening mechanisms for fertilizer production are mostly in an inclined state. The fertilizer particles are screened by rolling on the surface of the screen. When there are many fertilizer particles to be screened, when the fertilizer particles are concentrated and poured for screening, the upper particles will pile up and slide, and the expected screening effect cannot be achieved. In addition, the screens inside the existing reciprocating screening mechanisms for fertilizer production are all fixed structures. When it is necessary to screen particles of different sizes according to the type of fertilizer, it is inconvenient to replace screens of different specifications, which leads to a waste of working time. Utility Model Content

[0006] As a preferred embodiment, the shaking assembly includes two U-shaped plates, and the two U-shaped plates are fixedly mounted on one side surface of the two drainage frames. Support rods are connected between the inner wall surfaces of one side of the two U-shaped plates and the one side surface of the two drainage frames through bearings, and gears are fixedly mounted on the surfaces of the two support rods. Two racks are fixedly mounted between the two movable plates, and the two racks and the two gears are correspondingly meshed with each other.
[0007] As a preferred embodiment, a first sprocket is fixedly installed on the outer wall surface of the two support rods, a long plate is fixedly installed on one side surface of the two U-shaped plates, a forward and reverse motor is fixedly installed on one side surface of the long plate, and two second sprockets are fixedly installed on the output end of the forward and reverse motor, and chains are meshed on the surfaces of the two second sprockets, and the two chains are respectively meshed with the two first sprockets.
[0008] As a preferred embodiment, the two limit assemblies include two threaded rods, the two threaded rods are threadedly connected to one side surface of the two L-shaped plates, and a turntable is fixedly mounted on one end surface of the two threaded rods.
[0009] As a preferred embodiment, two cross bars are fixedly installed on the inner wall surface of one side of the two L-shaped plates, and a circular plate is fixedly installed on the end surface of the four cross bars away from the two L-shaped plates. The surfaces of each group of two of the four cross bars are slidably connected with a slide plate, and one side surface of the two slide plates is connected to the other end surface of the corresponding threaded rod through a bearing.
[0010] As a preferred embodiment, a limiting plate is fixedly installed on the other side surface of the two slides, a limiting groove is provided on one side surface of the two screening frames, and the two limiting plates are inserted into the corresponding limiting grooves.
[0011] Compared with the prior art, the advantages and positive effects of the utility model are:
[0012] 1. The utility model, when it is necessary to reciprocately screen the fertilizer particles, first add the fertilizer particles to be screened into the uppermost screening frame, and when the fertilizer particles are added, the forward and reverse motors are then operated by the external controller, and the operation of the forward and reverse motors drives the two second sprockets to rotate, the two second sprockets and the two chains are meshed with each other, and at the same time, the two chains are respectively meshed with the two first sprockets, and the two second sprockets rotate to rotate the two first sprockets, and the rotation of the two first sprockets drives the two support rods to rotate, and the rotation of the two support rods drives the two gears to rotate, and the two gears rotate and mesh with the two racks, so that the two racks move, and the movement of the two racks drives the two movable plates to move, and the two movable plates and the two L-shaped plates are slidably connected to the surfaces of multiple long rods, and the two screening frames are installed on the two movable plates and the two L-shaped plates. The two screening frames are placed between the mold plates, so that the two screening frames move back and forth. The back and forth movement of the two screening frames causes the fertilizer particles inside the screening frames to be displaced, which is beneficial for the screening frames to screen the fertilizer particles. The fertilizer particles screened by the top screening frame fall into the second screening frame, and the second screening frame also moves back and forth synchronously, so as to screen the fertilizer particles again, and the screened fertilizer particles fall into the collecting box. If the screening of the fertilizer particles inside the collecting box does not achieve the expected effect, the fertilizer particles inside the collecting box can be added to the first screening frame again, and reciprocating screening is performed until the expected effect is achieved. Through the cooperation of the above-mentioned structure, the two screening frames can shake synchronously, which is beneficial for the screening frames to screen the fertilizer particles. At the same time, it can also avoid the accumulation of fertilizer particles, block other particles from falling, and improve the screening effect of the device.
[0013] 2. According to the utility model, different kinds of fertilizer particles require screening frames of different specifications. When the screening frame needs to be replaced, the turntable is first rotated. The rotation of the turntable drives the threaded rod to rotate. The rotation of the threaded rod drives the slide plate to move on the surfaces of the two cross bars. The slide plate moves on the surfaces of the two cross bars to drive the limit plate to move. The limit plate moves to move itself out of the interior of the limit groove. The limit plate moves out of the interior of the limit groove, so that the multiple plug-in plates lose their limit in the interior of the multiple mounting plates. At this time, the two screening frames can be taken out and replaced with new screening frames. When the plug-in plate of the new screening frame is reinserted into the interior of the mounting plate, the turntable is rotated in the opposite direction at this time, so that the limit plate is reinserted into the corresponding limit groove, so as to limit the movement of the screening frame, and then the purpose of replacing the screening frame is completed. Through the cooperation of the above structure, the screening frame can be quickly disassembled and replaced to adapt to the screening of different kinds of fertilizer particles, which greatly saves working time.
