The filtration mechanism includes a first motor fixed at the right end of the housing, a first rotating shaft fixed to the output shaft of the first motor, and three cams fixed to the outer surface of the first rotating shaft. This fertilizer production and processing raw material filtration device has a filtration mechanism inside the casing, which allows fertilizer to be filtered and screened. At the same time, it can use shaking to prevent fertilizer from clogging the filter plate. The box is equipped with a crushing mechanism, which allows the fertilizer to undergo more cutting and crushing during the falling process, thereby improving the crushing efficiency. The overall filtration effect is good and can meet the crushing and filtration requirements of raw materials.

[0003] The above solution has the following shortcomings in practical application: blocky fertilizer is very easy to block the feed pipe, which prevents the fertilizer from falling into the inner cavity of the machine for crushing. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a filtration device for fertilizer production, which has the advantage of facilitating the extrusion of fertilizer into the crushing rollers and avoiding the problem of fertilizer clogging the feed pipe.

[0005] To facilitate the extrusion of fertilizer into the crushing rollers, this utility model provides the following technical solution:

[0006] A filtration device for fertilizer production includes a housing, a filter barrel fixedly connected to the bottom of the housing, a pulverizing assembly installed in the inner cavity of the housing for pulverizing fertilizer, and a filter assembly installed in the inner cavity of the filter barrel for filtering the pulverized fertilizer. The device also includes:

[0007] The crushing assembly includes two sets of first rotating shafts, which are rotatably mounted on the side wall of the housing. Crushing rollers are fixedly connected to the side wall of each first rotating shaft. A connecting pipe is fixedly connected to the top of the housing, and a feed pipe is fixedly connected to the side wall of the connecting pipe. A sliding column is slidably connected to the top of the connecting pipe, and a pressure block is fixedly connected to the bottom end of the sliding column located in the inner cavity of the connecting pipe.

[0008] According to some embodiments, a first servo motor is fixedly connected to the side wall of the housing, and the output end of the first servo motor is fixedly connected to a first rotating shaft. Gears are fixedly connected to the side wall of the first rotating shaft, and the gears are meshed together.

[0009] According to some embodiments, the filter assembly includes a filter plate, which is fixedly installed in the inner cavity of the filter barrel. The filter plate is configured in a U-shape.

Beneficial effects

[0011] This utility model provides a filtration device for fertilizer production, which has the following beneficial effects:

[0012] (1) The filter device for fertilizer production drives the first servo motor to rotate the first rotating shaft. Since the two sets of first rotating shafts are connected by gear meshing, the first rotating shafts rotate in opposite directions, which in turn causes the crushing rollers to rotate in opposite directions to crush the fertilizer. By pressing the sliding column, the sliding column drives the pressure block to slide down in the inner cavity of the connecting pipe, thereby squeezing the fertilizer into the crushing rollers, which facilitates the fertilizer to be crushed quickly by the crushing rollers and avoids fertilizer blockage.

[0013] (2) In the fertilizer production filtration device, the crushed fertilizer falls on the surface of the filter plate. Some of the fertilizer passes directly through the filter plate, while the remaining fertilizer and large particles remain on the surface of the filter plate. The rotating column drives the scraper to rotate, and the scraper can scrape the fertilizer on the surface of the filter plate into the space between the filter plate and the filter barrel. At the same time, the rotating column drives the L-shaped column to rotate, which can further crush the fertilizer in the filter plate and the filter barrel and pass it through the filter plate, thereby avoiding fertilizer clogging the filter plate.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1-5 A filtration device for fertilizer production includes a housing 1, a filter barrel 101 fixedly connected to the bottom of the housing 1, a crushing component 2 installed inside the housing 1 for crushing fertilizer, and a filter component 3 installed inside the filter barrel 101 for filtering the crushed fertilizer. The device also includes:

[0022] The crushing assembly 2 includes two sets of first rotating shafts 201. The first rotating shafts 201 are rotatably mounted on the side wall of the housing 1. Crushing rollers 202 are fixedly connected to the side wall of each first rotating shaft 201. A connecting pipe 203 is fixedly connected to the top of the housing 1. A feed pipe is fixedly connected to the side wall of the connecting pipe 203. A sliding column 204 is slidably connected to the top of the connecting pipe 203. A pressure block 205 is fixedly connected to the bottom end of the sliding column 204 located in the inner cavity of the connecting pipe 203. A spring 206 is fixedly connected between the pressure block 205 and the connecting pipe 203.

[0023] A first servo motor 207 is fixedly connected to the side wall of the housing 1, and the output end of the first servo motor 207 is fixedly connected to the first rotating shaft 201.

[0024] Gears 208 are fixedly connected to the side walls of the first rotating shaft 201, and the gears 208 are meshed together.

[0025] It should be noted that: when fertilizer is fed into the feed pipe, it enters the crushing rollers 202 inside the box 1 through the connecting pipe 203. The first servo motor 207 drives the first rotating shaft 201 to rotate. Since the two sets of first rotating shafts 201 are connected by gears 208, the rotation directions of the first rotating shafts 201 are opposite, which in turn causes the crushing rollers 202 to rotate in opposite directions, thus crushing the fertilizer. Furthermore, by pressing the sliding column 204, the sliding column 204 drives the pressing block 205 to slide down in the inner cavity of the connecting pipe 203, thereby squeezing the fertilizer between the crushing rollers 202, which facilitates the rapid crushing of the fertilizer by the crushing rollers 202 and avoids fertilizer blockage.

[0026] Reference Figures 1-5 The filter assembly 3 includes a filter plate 301, which is fixedly installed in the inner cavity of the filter barrel 101 and is configured in a Z-shape.

[0027] A rotating column 302 is rotatably connected to the top of the filter plate 301, and a scraper 303 is fixedly connected to the side wall of the rotating column 302, and the scraper 303 is in contact with the surface of the filter plate 301.

[0028] An L-shaped column 304 is fixedly connected to the side wall of the rotating column 302, and the L-shaped column 304 is located between the filter plate 301 and the inner wall of the filter barrel 101. A protective cover 305 is fixedly connected to the top of the rotating column 302. The scraper 303 and the L-shaped column 304 are perpendicular to each other.

[0029] It should be noted that after the fertilizer is crushed, it falls onto the surface of the filter plate 301. Some of the fertilizer passes directly through the filter plate 301, while the remaining fertilizer and large particles remain on the surface of the filter plate 301. The rotating column 302 drives the scraper 303 to rotate, which can scrape the fertilizer on the surface of the filter plate 301 into the space between the filter plate 301 and the filter barrel 101. At the same time, the rotating column 302 drives the L-shaped column 304 to rotate, which can further crush the fertilizer in the filter plate 301 and the filter barrel 101 and pass it through the filter plate 301. This can prevent the fertilizer from clogging the filter plate 301.

[0030] Reference Figures 1-5 A second servo motor 4 is fixedly connected to the top of the filter barrel 101. A second rotating shaft 401 is fixedly connected to the output end of the second servo motor 4. A sprocket 402 is fixedly connected to both the second rotating shaft 401 and the side wall of the rotating column 302. A track 403 is rotatably connected between the sprockets 402.

[0031] The scraper 303 is fixedly connected to the end of a first arc plate 404, and the first arc plate 404 is in contact with the inner wall of the filter barrel 101. The bottom inner wall of the filter barrel 101 is set to arc shape. The rotating column 302 is fixedly connected to the side wall of a second arc plate 405, and the second arc plate 405 is in contact with the bottom inner wall of the filter barrel 101.

[0032] It should be noted that: the second servo motor 4 drives the second rotating shaft 401 to rotate. Since there is a track 403 between the rotating column 302 and the sprocket 402 on the side wall of the second rotating shaft 401, the second rotating shaft 401 drives the rotating column 302 to rotate. The first arc plate 404 and the second arc plate 405 follow the rotating column 302 to rotate, which can prevent fertilizer from sticking to the side wall of the filter bucket 101. The protective cover 305 can prevent fertilizer from falling directly onto the sprocket 402, thus playing a protective role.

[0033] Operating method: Fertilizer is fed into the feed pipe and enters the crushing rollers 202 in the inner cavity of the box 1 through the connecting pipe 203. The first servo motor 207 is driven to rotate the first rotating shaft 201. Since the two sets of first rotating shafts 201 are connected by gears 208, the rotation directions of the first rotating shafts 201 are opposite, which in turn makes the crushing rollers 202 rotate in opposite directions, thus crushing the fertilizer. The sliding column 204 can be pressed, and the sliding column 204 drives the pressing block 205 to slide down in the inner cavity of the connecting pipe 203, thereby squeezing the fertilizer into the crushing rollers 202, which facilitates the rapid crushing of the fertilizer by the crushing rollers 202 and avoids fertilizer blockage.

[0034] The second servo motor 4 drives the second rotating shaft 401 to rotate. Since there is a track 403 between the rotating column 302 and the sprocket 402 on the side wall of the second rotating shaft 401, the second rotating shaft 401 drives the rotating column 302 to rotate. The crushed fertilizer falls on the surface of the filter plate 301. Some of the fertilizer passes directly through the filter plate 301, while the remaining fertilizer and large particles remain on the surface of the filter plate 301. The rotating column 302 drives the scraper 303 to rotate. The scraper 303 can scrape the fertilizer on the surface of the filter plate 301 into the space between the filter plate 301 and the filter barrel 101. At the same time, the rotating column 302 drives the L-shaped column 304 to rotate, which can further crush the fertilizer in the filter plate 301 and the filter barrel 101 and pass it through the filter plate 301. This can prevent the fertilizer from clogging the filter plate 301.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
