An electric push rod 11 and a pressure plate 12 are provided, the bottom end of the electric push rod 11 is hinged with a hinge seat 13, the hinge seat 13 is fixed in the rear opening 10, the telescopic end of the electric push rod 11 is fixed with a connecting plate 14, the connecting plate 14 is rotatably connected with a connecting rod 15 through a bearing, the connecting rod 15 is fixed to the pressure plate 12, a sieve plate 22 is provided in the frame 1, one end of the sieve plate 22 is fixed to the rotating rod 4, a spring 23 is connected between the sieve plate 22 and the guide plate 2, a positioning rod 24 is fixed between the front and rear side walls of the inner cavity of the frame 1, and the positioning rod 24 is located below the sieve plate 22;
[0037] A support frame 16 is provided, and slide rails 17 are fixedly connected to the left and right sides of the top of the support frame 16. The slide rails 17 are slidably connected to the slide groove 7. A motor 18 is installed on the left side of the bottom of the support frame 16. A disc 19 is fixedly connected to the output end of the motor 18. An eccentric rod 20 is fixedly connected to the side wall of the disc 19 away from the motor 18. A swing arm 21 is rotatably connected between the eccentric rod 20 and the push-pull rod 9 through a bearing.
[0038] Preferably, if Figure 2 and Figure 4 As shown, the lower end of the slag discharge port 5 and the lower end of the rear opening 10 are both inclined, and a slag discharge plate 25 is provided on the outer side of the lower end of the slag discharge port 5. The slag discharge plate 25 is fixedly connected to the outer wall of the frame 1. The agglomerated large fertilizers sliding down from the screen plate 22 are discharged from the slag discharge port 5 and discharged by the slag discharge plate 25 into the slag collecting box 50 below. The lower end of the rear opening 10 is inclined to prevent the fertilizer from being spilled from the rear opening 10.
[0039] Furthermore, if Figure 1 and Figure 2 As shown, the avoidance opening 6 is arc-shaped, and the end of the sieve plate 22 away from the rotating rod 4 is inserted into the avoidance opening 6, so that the sieve plate 22 has enough space to swing and discharge unqualified large agglomerated fertilizer residues.
[0040] Furthermore, if Figure 6 As shown, the sieve plate 22 includes a sieve portion 221 and a guide portion 222. The front and rear side walls of the sieve portion 221 and the guide portion 222 are smoothly abutted against the inner cavity side wall of the frame 1. The sieve portion 221 screens the fertilizer, and the guide portion 222 facilitates the diversion of unqualified fertilizers from the slag discharge port 5.
[0041] Furthermore, if Figure 2 and Figure 4 As shown, the screen portion 221 is located below the pressure plate 12, and the bottom end of the guide plate 2 is located above the screen portion 221. The guide portion 222 and the guide plate 2 are fixedly connected with hook rings 26 on one side close to each other, and the spring 23 is hooked between the two groups of hook rings 26. The guide plate 2 guides the fertilizer entering the frame 1 to fall onto the screen portion 221 for screening, and the spring 23 facilitates the screen plate 22 to swing upward and reset.
[0042] Specifically, Figure 3 As shown, the length of the slide groove 7 is less than the length of the slide rail 17, which facilitates the frame 1 to swing on the support frame 16 so that the screen plate 22 can screen the fertilizer.
[0043] Furthermore, if Figure 2 and Figure 4 As shown, a shaft rod 27 is fixedly connected to the pressing plate 12, and the shaft rod 27 is rotatably connected to the rear opening 10 through a bearing. The pressing plate 12 is V-shaped, and an avoidance groove 28 is provided on an arm of the pressing plate 12 close to the connecting plate 14, and the connecting rod 15 is arranged in the avoidance groove 28. The end of the pressing plate 12 away from the connecting plate 14 abuts against the sieve plate 22. When it is necessary to discharge large lumps of unqualified fertilizer, the electric push rod 11 is started, and the telescopic end of the electric push rod 11 extends through the connecting plate 14 and the connecting rod 15 to drive the pressing plate 12 to rotate around the shaft rod 27. The avoidance groove 28 avoids the electric push rod 11, and the long end of the pressing plate 12 presses down the sieve plate 22 to rotate around the rotating rod 4, the spring 23 is stretched, and the sieve plate 22 swings and tilts to the lower right, and the unqualified fertilizer is discharged from the slag discharge port 5.
[0044] Furthermore, if Figure 1 and Figure 2 As shown, a feeding port 29 is provided on the support frame 16, and the feeding port 29 is located below the frame 1. The width of the feeding port 29 is greater than the inner cavity width of the frame 1. The qualified fertilizer screened by the sieve plate 22 passes through the lower end of the frame 1 and the feeding port 29 and falls into the collecting box 40 below.
[0045] A specific application of the present application is: the utility model is suitable for screening during the production of potassium sulfate and magnesium fertilizers. When in use, the electric push rod 11 is in a retracted state in the initial state. Due to the position of the elastic force of the spring 23, the right end of the sieve plate 22 is kept higher than its left end. The pressure plate 12 is pressed on the sieve plate 22, and the potassium sulfate and magnesium fertilizers to be screened are injected into the frame 1. When the maximum amount of fertilizer that can be carried is injected, the tension of the spring 23 can support so that the right end of the sieve plate 22 is higher than its left end, and then the motor 18 is started to drive the disc 19 to rotate, and the eccentric rod 20 cooperates with the swing arm 21 to drive the push-pull rod 9 to move back and forth, and the driving rod 8 drives the frame 1 to move back and forth, and the slide rail 17 cooperates with the slide slot 7 to guide the frame 1. The screen part 221 on the sieve plate 22 screens the fertilizer, and qualified fertilizer passes through the screen. The part 221 falls from the drop port 29 into the collecting box 40 below. When only large lumps of unqualified fertilizer are left on the screen part 221 after screening, the electric push rod 11 is started, and the telescopic end of the electric push rod 11 is extended. The connecting plate 14 and the connecting rod 15 drive the pressing plate 12 to rotate around the shaft 27. The long end of the pressing plate 12 presses the sieve plate 22 downward, and the sieve plate 22 tilts to the lower right. The spring 23 is stretched, and the positioning rod 24 positions the sieve plate 22 so that its right end is located in the slag discharge port 5. Then the unqualified fertilizer is discharged from the slag discharge port 5 and the slag discharge plate 25 through the guide part 222 and falls into the slag collecting box 50 below. After the slag discharge is completed, the electric push rod 11 is reset. Due to the tension of the spring 23, the right end of the pressing plate 12 is driven to rise, so that the right end is higher than the left end again, which is convenient for the next fertilizer injection and screening operation.
[0046] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the present application in detail. It should be understood that the above description is only the specific implementation method of the present application and is not intended to limit the scope of protection of the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the scope of protection of the present application.
