[0027] As Figures 1 to 6 The utility model discloses a fertilizer mixer with screening structure similar to the structure of the existing fertilizer mixer with screening structure, such as the patent No. CN217568947U discloses a mixer feeding mechanism, the main improvement of the utility model lies in ensuring that the fertilizer particles are more uniform during mixing and stirring, improving the quality of compound fertilizer, such as Figures 1 to 6 As shown in the utility model, the fertilizer to be mixed is added from above the mixer feed tank 1 during use, the crushing of the rubbing roller 2 can reduce the blocky fertilizer in the fertilizer, and then the crushed fertilizer falls on the screen 4, the reciprocating movement of the screening frame 3 and the screen 4 in the installation hole 101 is driven by the reciprocating screening drive component and the reset component, thereby forming a screening movement, screening the falling fertilizer, ensuring that the fertilizer particles entering the mixer are more uniform, leaving the large-particle fertilizer on the screen 4, improving the mixing effect of the fertilizer, making the mixed compound fertilizer more beneficial to the absorption of field crops, and improving the quality of fertilizer mixing and stirring.

[0028] As Figures 1 to 6 As shown, the screening frame 3 is designed in an arc shape, which is beneficial to the concentration of large-particle fertilizer at the bottom of the screen 4, facilitating collection and processing.

[0029] As Figures 1 to 3 As shown, the reset component includes a T-shaped frame 5, a push plate 6, and a plurality of reset springs 7, one end of the T-shaped frame 5 is fixedly connected with the lateral wall of the mixer feed tank 1, the other end of the T-shaped frame 5 is fixedly connected with the plurality of reset springs 7 near one side of the mixer feed tank 1, the other end of each reset spring 7 is fixedly connected with the push plate 6, and the other side of the push plate 6 abuts against one end of the screening frame 3. The screening frame 3 can always be extruded to the other side through the T-shaped frame 5, the plurality of reset springs 7, and the push plate 6, and cooperates with the reciprocating screening drive component on the other side, so that the screening frame 3 reciprocates in the installation hole 101, and screens the fertilizer particles.

[0030] As Figures 1 to 3As shown, the reset spring 7 is provided with a limiting rod 8, one end of the limiting rod 8 is fixedly connected with the push plate 6, and the other end penetrates the T-shaped frame 5 and is in sliding connection with the T-shaped frame 5. The limiting rod 8 can limit the extension state of the reset spring 7, avoiding the bending of the reset spring 7.

[0031] As shown in the figure, Figures 1 to 6 The reciprocating screening drive assembly includes a drive motor 9 and an eccentric wheel 10. The drive motor 9 is vertically arranged on one side of the mixer feed tank 1. The output shaft of the drive motor 9 is fixedly connected with the eccentric wheel 10. The eccentric wheel 10 abuts against one end of the screening frame 3 away from the reset assembly. The outer wall of the drive motor 9 is connected with a displacement assembly. The displacement assembly is connected with the side wall of the mixer feed tank 1. Starting the drive motor 9 drives the eccentric wheel 10 to rotate, cooperating with the reset spring 7 on the other side, so that the screening frame 3 reciprocates between the push plate 6 and the eccentric wheel 10.

[0032] As shown in the figure, Figure 2 The displacement assembly includes a T-shaped suspender 11 and a support rod 12. The support rod 12 is fixedly connected with the side wall of the mixer feed tank 1. The thinner end of the T-shaped suspender 11 penetrates the support rod 12 from top to bottom and is fixedly connected with the drive motor 9. By sliding the T-shaped suspender 11 up and down on the support rod 12, the eccentric wheel 10 can be moved upwards and separated from the screening frame 3. At this time, the screening frame 3 can be pulled out of the mounting hole 101, so that the screened large particle fertilizer can be taken out for crushing treatment. The mounting hole 101 above the take-out end can increase the opening area, facilitating the smooth taking out of the large particle fertilizer screened on the screen 4.

[0033] As shown in the figure, Figures 4 to 6 The upper surface of the screening frame 3 is provided with a mounting groove 301. The mounting groove 301 is connected with a net clamping frame 13. The screen 4 is located between the mounting groove 301 and the net clamping frame 13. The net clamping frame 13 can clamp the screen 4 tightly in the mounting groove 301, facilitating the replacement of the screen 4 according to different needs.

[0034] As shown in the figure, Figures 4 to 6 The same side of the net clamping frame 13 and the screening frame 3 is fixedly connected with a plurality of hinges 14. The two ends of the plurality of hinges 14 are respectively embedded in the net clamping frame 13 and the screening frame 3. The inner side of the net clamping frame 13 away from the hinge 14 is embedded with a magnetic strip 15. The two magnetic strips 15 are magnetically attracted to each other. The plurality of hinges 14 facilitates the opening of the net clamping frame 13 from the mounting groove 301. The two magnetic strips 15 are magnetically attracted to each other, facilitating the clamping and fixing of the screen 4 in the mounting groove 301 by the net clamping frame 13.

[0035] As shown in the figure, Figure 5 The inner wall of the mounting groove 301 is fixedly connected with a plurality of mesh nails 16. The plurality of mesh nails 16 can nail the edge of the screen 4 in the mounting groove 301, avoiding the falling of the screen 4 from the mounting groove 301.

[0036] like Figure 3 As shown, support rods 17 are fixedly connected to the inner walls of both sides of the mixer feed box 1, and the bottom sides of the screening frame 3 are slidably connected to the two support rods 17 respectively. By supporting the bottom of the screening frame 3 with the two support rods 17, the stability of the screening frame 3 in reciprocating movement within the mounting hole 101 can be improved.
