Description

Technical Field

[0001] The utility model relates to the technical field of organic-inorganic compound fertilizer production, in particular to an adjustable multi-stage screening device. Background Technique

[0002] Organic-inorganic compound fertilizer is a compound fertilizer containing both organic matter and appropriate chemical fertilizers. It is a commercial fertilizer prepared by harmless and effective treatment of organic materials such as feces and peat through microbial fermentation, adding appropriate chemical fertilizers and humic acid, and granulating or directly blending. When put into use, it is necessary to screen the compound fertilizer first to screen out large impurities and materials that are inconvenient for subsequent processing, so as to ensure the subsequent processing efficiency.

[0003] At present, most of the existing organic-inorganic compound fertilizers are screened by first screening them once, collecting the screened materials, and then replacing the filter screen and pouring the screened materials back into the device for screening again. The operation is relatively cumbersome and inconvenient to use. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technical staff in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1 to 4, the present utility model provides a technical solution: an adjustable multi-stage screening device, including a multi-stage screening box body 1. Three installation grooves 11 are provided inside the multi-stage screening box body 1. A blocking side plate 15 is slidably installed inside each installation groove 11. A screening frame 2 is slidably installed inside each installation groove 11. A filter screen 24 is installed inside each screening frame 2. Two rotating rods 22 are rotatably installed inside each screening frame 2. A leak box 16 is fixedly installed at the upper end of the multi-stage screening box body 1. A storage box 17 is slidably installed at the lower end of the multi-stage screening box body 1.

[0020] In this embodiment, as Figure 1 and Figure 2 shown, connection grooves 12 are provided on both the upper and lower sides of each installation groove 11. First limiting grooves 13 are provided on the upper and lower sides of the front and rear sides of each installation groove 11. This structure can facilitate the quick installation of the subsequent screening frame 2 part through the first limiting grooves 13 provided inside the installation groove 11 during use and limit it to prevent deviation.

[0021] In this embodiment, as Figure 1 , Figure 2 and Figure 3 shown, second limiting grooves 14 are provided at the side ends of each installation groove 11. Each blocking side plate 15 is slidably installed inside the installation groove 11 by cooperating with the second limiting grooves 14. This structure can facilitate the sliding installation of the blocking side plate 15 through the second limiting grooves 14 provided at the side ends of the installation groove 11 during use, thereby blocking the screening frame 2 and preventing it from rushing out of the installation groove 11 during the sliding process.

[0022] In this embodiment, as Figure 1 and Figure 3 shown, a second fixed handle 21 is fixedly installed at the side end of each screening frame 2. The side ends of the two rotating rods 22 installed inside the screening frame 2 are both installed with the same transmission belt 23. This structure can drive the rotating rods 22 to rotate through the cooperation of the motor inside the screening frame 2 and the transmission belt 23 during use, thereby causing the filter screen 24 to shake and perform screening.

[0023] In this embodiment, as Figure 1 and Figure 4 shown, a first fixed handle 18 is fixedly installed at the side end of the storage box 17. Two blocking top plates 19 are slidably installed at the upper end of the storage box 17. This structure can hold the screened materials through the storage box 17 during use and cooperate with the blocking top plates 19 to isolate them from the outside to avoid contamination.

[0024] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, each installation groove 11 communicates with other installation grooves 11 through connection grooves 12. Each screening frame 2 is slidably installed inside the installation groove 11 by matching the upper and lower protrusions with the first limiting groove 13. This structure can cooperate with the connection groove 12 and the installation groove 11 during use to introduce the materials falling from the leakage box 16 into the multi-stage screening box 1 into the screening frame 2 for rapid screening, thereby improving the use efficiency of the device.

[0025] The usage method and advantages of the present utility model: For this adjustable multi-stage screening device, during use, the working process is as follows:

[0026] Such as Figure 1 、 Figure 2 、 Figure 3 And Figure 4As shown, first, when in use, the user places the device on a horizontal surface. The user picks up the multi-stage screening box body 1, installs the leakage box 16 above the multi-stage screening box body 1, then picks up the storage box 17, installs the first fixed handle 18 on the side end of the storage box 17, and then installs two blocking top plates 19 above the storage box 17. Subsequently, the assembled storage box 17 is placed below the multi-stage screening box body 1. Then the user picks up the screening frame 2, installs two rotating rods 22 inside the screening frame 2, installs the filter screen 24 above the two rotating rods 22, installs the second fixed handle 21 on one side of the screening frame 2, and then uses a transmission belt 23 to connect the two rotating rods 22 on one side of the rotating rod 22. Subsequently, a rotating motor is installed on one side of the screening frame 2 away from the transmission belt 23. After assembling three screening frames 2, the user installs the three screening frames 2 into the three installation slots 11 respectively along the first limiting slots 13 opened in the three installation slots 11 opened on the upper and lower sides of the screening frame 2 and the raised parts on the upper and lower sides of the screening frame 2. Then, a blocking side plate 15 is installed at the side end of each installation slot 11 along the second limiting slot 14 opened at the side end of the installation slot 11. When the user needs to use the device, the user pulls the second fixed handle 21 according to the pore size to be screened. The second fixed handle 21 cooperates with the raised parts on the upper and lower sides of the screening frame 2 and the first limiting slot 13 to drive the whole screening frame 2 to slide left and right in the installation slot 11, so as to slide the required screening frame 2 to the position where connection slots 12 are opened on the upper and lower sides of the installation slot 11. Subsequently, the motor on one side of the rotating rod 22 is started. The motor cooperates with the transmission belt 23 to drive the two rotating rods 22 to rotate. Cooperating with the raised parts installed on the outer surfaces of the two rotating rods 22, the filter screen 24 is successively lifted. Then the user pours the organic-inorganic compound fertilizer to be screened into the leakage box 16, and the fertilizer is introduced into the installation slot 11 through the cooperation of the leakage box 16 and the upper connection slot 12, and is screened by the screening frame 2 part, so that the fertilizer meeting the size falls into the lower storage box 17 for collection. The user can freely adjust the screening pore size according to needs. If there is no suitable pore size in the device, the user can also slide the blocking side plates 15 to the front and back sides to remove the blocking side plates 15, and then slide the screening frame 2 to take out the screening frame 2 to replace the internal filter screen 24, so as to facilitate adjustment.
