[0019] The stirring mesh 6 is arranged in an arc shape, and the fertilizer raw material particles located in the filter frame 4 are pushed by the stirring mesh 6. When the stirring mesh 6 is pushed to be flush with the third guide plate 105, the arc-shaped stirring mesh 6 promotes the screened fertilizer raw material particles to fall quickly onto the third guide plate 105.

[0020] The crushing assembly includes crushing blades 106 and a rotating ring 107; each fixed plate 4001 is rotatably connected to a rotating ring 107; the two rotating rings 107 are commonly fixed with a number of crushing blades 106, the number of which is the same as the number of the stirring meshes 6; the crushing blades 106 are arc-shaped.

[0022] A dust cover 2003 is detachably connected to the upper part between the two blocking plates 2001; the dust cover 2003 blocks the dust generated when filtering the fine fertilizer raw material particles.

[0023] The first guide plate 102 is coated with an alloy coating.

[0024] The bottom surface of the collecting frame 103 is inclined to facilitate the discharge of the collected fertilizer raw material particles.

[0025] The present invention aims at the existing conveyor 2 for fertilizer granulation and transportation. In the whole process of conveying fertilizer raw material particles, fine particles and fine particle powder in the fertilizer raw material particles will raise dust, causing dust pollution, and in the process of conveying fertilizer raw material particles, some fertilizer raw material particles will be lost, causing the problem of ratio error. The present invention is provided with a filter frame 4 and a stirring mesh 6; a discharge bin is installed on the left side of the present invention, and a weighing bin for weighing and ratio is installed on the right side; when using the present invention, the conveyor 2 is started, and the conveyor 2 drives the conveyor belt 3 to run clockwise from front to back, and the fertilizer raw material particles in the discharge bin are transported to the right side. During the transportation process, the fertilizer raw material particles are transported to the first guide plate 102, fall from the first collecting tank 10303 along the surface of the first guide plate 102, and enter the collecting frame 103. When the height of the fertilizer raw material particles is the same as that of the second collecting tank 1 When the lower side of 0302 is flush, the sliding plate 10301 is driven to slide upwards by the electric slider 10304, and the collected fertilizer raw material particles fall from the collecting frame 103 into the filtering frame 4. During the process of conveying the fertilizer raw material particles by the conveyor belt 3, the rotating motor 101 drives the rotating roller 5 to rotate counterclockwise from front to back, and the rotating roller 5 drives the stirring mesh 6 to rotate counterclockwise. After the fertilizer raw material particles enter the filtering frame 4, the sliding plate 10301 is driven to slide downwards by the electric slider 10304, and the collecting frame 103 is closed. The stirring mesh 6 rotates and pushes the fertilizer raw material particles entering the filtering frame 4 to move rightward along the filtering frame 4 for transportation. In this process, the fine powder in the fertilizer raw material particles falls downward through the filtering frame 4, and the fallen fine powder is collected in the collecting part 2004 and discharged regularly through the collecting pipe 2002. Figure 4As shown, when the stirring mesh 6 that pushes the fertilizer raw material particles is flush with the third guide plate 105, the fertilizer raw material particles after the fine powder is screened out are located on the upper side of the stirring mesh 6, and the fertilizer raw material particles after the fine powder is screened out fall along the surface of the stirring mesh 6 to the third guide plate 105, and further return to the conveyor belt 3 along the third guide plate 105, and continue to be conveyed to the weighing bin on the right side of the conveyor belt 3, thereby realizing the screening out of fine powder in the initial conveying stage, and effectively avoiding the dust phenomenon in the subsequent conveying process. At the same time, before the fertilizer raw material particles enter the weighing bin for weighing and proportioning, the fine powder has been screened out, thereby avoiding the loss of fertilizer raw material particles due to the dust phenomenon generated by the fine powder after the fertilizer raw material particles are weighed, and causing the proportioning error problem.

[0026] When the fertilizer raw material particles are located in the filter frame 4 and the fine powder is screened out, the fertilizer raw material particles enter the filter frame 4. Figure 7 As shown in the stirring mesh 6 and the crushing blade 106 on the lower left side, the fertilizer raw material particles that meet the specifications pass through the crushing blade 106 located in the filter frame 4, and the agglomerated fertilizer raw material particles are intercepted by the crushing blade 106. It should be noted that at this time, the rotating ring 107 stops driving the crushing blade 106 to rotate, and the stirring mesh 6 is located outside the filter frame 4. Then the stirring mesh 6 rotates into the filter frame 4. Figure 7 When the agglomerated fertilizer raw material particles are in the position shown in the figure, the stirring mesh 6 and the crushing leaves 106 cooperate to sandwich the agglomerated fertilizer raw material particles between the stirring mesh 6 and the crushing leaves 106. Since the rotating ring 107 is rotatably connected to the fixed plate 4001, the fixed plate 4001 drives the rotating ring 107 to vibrate back and forth together, and the rotating ring 107 drives the crushing leaves 106 fixed thereon to vibrate. The crushing leaves 106 rub the intercepted agglomerated fertilizer raw material particles back and forth to disperse the agglomerated fertilizer raw material particles. After the agglomerated fertilizer raw material particles are dispersed, the rotating ring 107 connected to the fixed plate 4001 is rotated counterclockwise from the front to the back to accelerate the rotation, driving the crushing leaves 106 fixed thereon to rotate, so that the stirring mesh 6 and the crushing leaves 106 are in a state of being ... Figure 4 After the state shown, they rotate at a uniform speed, and the stirring mesh 6 pushes the fertilizer raw material particles in the filter frame 4 to be transported to the third guide plate 105, and then transported to the conveyor belt 3 from the third guide plate 105. Through the cooperation between the stirring mesh 6 and the crushing leaves 106, and the transverse vibration motor drives the filter frame 4 to vibrate back and forth, and then drives the rotating ring 107 to vibrate, and the rotating ring 107 drives the crushing leaves 106 to vibrate, the screening of the fertilizer raw material particles is accelerated and the agglomerated fertilizer raw material particles are kneaded, thereby solving the agglomeration problem of the fertilizer raw material particles.

[0027] Furthermore, in order to prevent dust from being generated near the collecting portion 2004 during the screening of the fertilizer raw material particles in the filter frame 4, a dust cover 2003 is provided to prevent the screened fine powder from being scattered in the external environment.

[0028] Furthermore, in order to ensure that all the transported fertilizer raw material particles can smoothly enter the collecting frame 103, a second guide plate 104 is added below the first guide plate 102 to provide secondary guidance for the fertilizer raw material particles that accidentally fall downward. The fertilizer raw material particles guided by the second guide plate 104 will eventually smoothly enter the collecting frame 103 from the second collecting trough 10302, thereby improving material utilization and reducing production interruptions and efficiency reduction.

[0029] Example 2 On the basis of Example 1, Figure 2-Figure 7 As shown, it includes a separation airbag 205; a plurality of evenly distributed separation airbags 205 are fixedly connected to the conveyor belt 3, a connecting plate is provided at the lower side of the separation airbag 205, and a pipe connected to the separation airbag 205 is opened on the connecting plate; a connecting pipe 20501 is connected on the connecting plate; the fertilizer raw material particles rolling downward are blocked by the separation airbag 205.

[0030] It also includes a support plate 201, a sliding block 202, a driving member 203, an air pump 204 and a ventilation pipe 208; two support plates 201 are fixedly connected to the conveyor 2, and the support plates 201 are respectively located on the left and right sides of the blocking plate 2001; the support plates 201 have the same inclination angle as the upper side of the conveyor belt 3; each support plate 201 is provided with a slide groove 20101; a sliding block 202 is slidably connected in the slide groove 20101; a driving member 203 is fixedly connected to the sliding block 202, and the driving member 203 is an electric push rod; an air pump 204 is fixedly connected to the output end of the driving member 203; the ventilation pipe 208 is connected to the ventilation pipe 208; the inner diameter of the ventilation pipe 208 is the same as the outer diameter of the connecting pipe 20501.

[0031] It also includes a cleaning roller 206 and a fixing frame 207; the two blocking plates 2001 are fixedly connected to the fixing frame 207; the cleaning roller 206 is rotatably connected to the fixing frame 207; the cleaning roller 206 is driven to rotate by an electric motor.

[0032] In order to facilitate centralized control of the transportation of fertilizer raw materials, the present invention adopts an inclined arrangement to transport fertilizer raw material particles, which easily causes the fertilizer raw material particles to roll and slide from the upper left to the lower right along the surface of the conveyor belt 3, resulting in the fertilizer raw material particles gathering or overflowing during the transportation process. Figure 3 As shown, separation airbags 205 are evenly distributed on the conveyor belt 3, and the separation airbags 205 are used to evenly separate the fertilizer raw material particles, block the fertilizer raw material particles from sliding downward, and avoid the problem of large-scale accumulation of fertilizer raw material particles.

[0033] Since the fertilizer raw material particles sliding downward are blocked by the separation airbag 205, some fine powders are easy to adhere to the separation airbag 205 and the conveyor belt 3 and are difficult to clean. Figure 6When the position is shown, the output end of the vent pipe 208 is driven to move toward the separation airbag 205, driving the air pump 204 fixed thereto and the vent pipe 208 to move toward the connecting pipe 20501, so that the vent pipe 208 is connected with the connecting pipe 20501. An air valve is provided at the mouth of the connecting pipe 20501. When the vent pipe 208 is connected with the connecting pipe 20501, the air valve is opened. When the vent pipe 208 leaves the connecting pipe 20501, the air valve is closed, and the air pump 204 is started to deflate the separation airbag 205. It takes a certain amount of time for the airbag 205 to be deflated. During the deflation of the airbag 205, the sliding block 202 moves to the lower right along the slide groove 20101, and the sliding block 202 drives the driving member 203, the air pump 204 and the vent pipe 208 to move together until the deflation of the airbag 205 is completed. It should be noted that after the deflation of the airbag 205 is completed, in order to ensure the continuity of the deflation of the airbag 205 on the conveyor belt 3, the reset speed of the sliding block 202 driving the driving member 203, the air pump 204 and the vent pipe 208 is greater than The conveying speed of the conveyor belt 3 is faster to ensure that the air pump 204 and the vent pipe 208 can deflate the next separation airbag 205. The deflated separation airbag 205 no longer blocks the fertilizer raw material particles, and the fertilizer raw material particles can slide to the first guide plate 102, and then enter the collection frame 103 and the filter frame 4 to complete the operation of screening out fine powder. The deflated separation airbag 205 is continuously conveyed with the conveyor belt 3. When the deflated separation airbag 205 is conveyed to the right side of the cleaning roller 206 with the conveyor belt 3, the electric motor The driving cleaning roller 206 is continuously rotating, and the conveyor belt 3 and the separation airbag 205 are cleaned by the continuously rotating cleaning roller 206. After the cleaning is completed, when it is transported to the right side of the third guide plate 105, the connecting pipe 20501 is connected to the ventilation pipe 208 located on the right side, and the separation airbag 205 is inflated by the air pump 204 in the same operation to restore the blocking and separation effect on the fertilizer raw material particles, while also preventing fine powder from adhering to the conveyor belt 3 and the separation airbag 205 that have completed the transportation and screening of the fertilizer raw material particles.
