Description

Technical Field

[0001] The present application relates to the technical field of fertilizer screening, and more specifically, to a fertilizer particle screening device. Background Art

[0002] Fertilizer screening is the process of screening the produced fertilizers according to particle size for the purpose of dividing and measuring them for easy distribution.

[0003] The document with the prior art disclosure (announcement) number CN220277594U provides a screening device for granular fertilizers. In the related technology of the device, a limiting column, a screen plate, an arc plate, etc. are arranged. When in use, the granular fertilizers are placed in a fixed shell, and the motor is started to drive the first gear and the second gear to rotate, so that the limiting column rotates in the fixed shell, and the scraper rotates accordingly. The spacing between the four scrapers is adapted to the rectangular hole, so that intermittent feeding of the screen plate can be realized to prevent excessive feeding and affect the screening efficiency. The T-shaped column rotates to drive the convex plate to continuously hit the arc plate, and the collecting shell moves up and down, so that the sliding block slides on the sliding column, and continuously compresses the buffer spring, so that the screen plate and the collecting shell vibrate continuously, and the granular fertilizers screened by the vibration are discharged from the first discharge port and the second discharge port respectively, thereby realizing intermittent feeding of the granular fertilizers and improving the screening efficiency of the granular fertilizers. At the same time, the device is simple to operate, improves practicality, and reduces energy consumption.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: the screening level of the device is fixed and it does not have the effect of flexibly adjusting the screening level.

[0005] In view of this, we propose a fertilizer particle screening device. Utility Model Content

[0032] The following further elaborates on this application in conjunction with the attached drawings of the specification.

[0033] Refer to Figure 1 , in a fertilizer granule screening device described in an embodiment of this application, a fertilizer granule screening device includes:

[0034] Power facility frame 1;

[0035] Hopper 2, fixedly connected to one end of the power facility frame 1;

[0036] Main sieve hopper 3, hingedly installed in the power facility frame 1 through a plurality of connecting rods;

[0037] Driving motor 4, fixedly connected to one side of the power facility frame 1 through a motor frame and connected and limited to the main sieve hopper 3;

[0038] Grading sieve hopper 5, clamped and matched with the main sieve hopper 3 through a positioning pin and connected and fixed through a buckle.

[0039] In this fertilizer granule screening device, multiple grading sieve hoppers 5 are flexibly docked and installed with the main sieve hopper 3 by using positioning pins and are connected and fixed under the action of buckles, enabling the device to be installed and used in multiple levels according to usage requirements and improving the flexibility of device use.

[0040] Refer to Figure 2 and Figure 1 , on one side of the power facility frame 1 in the fertilizer granule screening device described in an embodiment of this application, a cross bar 11 is fixedly connected, a toothed plate 12 is fixedly connected to one side of the cross bar 11 arranged in an L-shaped structure, and a transmission gear 13 is meshed and fitted on one side of the toothed plate 12.

[0041] In this fertilizer granule screening device, through the transmission of the installed and fixed cross bar 11 on the toothed plate 12, it is ensured that under the shaking and screening of the driving motor 4, the turbulence paddle 7 installed in the main sieve hopper 3 rotates under the transmission of the transmission gear 13 to stir the falling and rolling fertilizer granules, improving the screening effect.

[0042] Refer to Figure 3 and Figure 1, in the fertilizer particle screening device described in the embodiments of the present application, a plurality of baffle plates 6 are fixedly connected in both the main sieve hopper 3 and the grading sieve hopper 5 with a hollow structure. A plurality of turbulence paddles 7 are rotatably connected in both the hopper 2 and the main sieve hopper 3. The adjacent two turbulence paddles 7 can be inserted and matched with each other. The two turbulence paddles 7 in the main sieve hopper 3 are frictionally driven by a sprocket chain, and one of the turbulence paddles 7 in the main sieve hopper 3 is fixedly connected to the transmission gear 13.

[0043] In this fertilizer particle screening device, the falling and rolling fertilizer particles are blocked by the baffle plate 6, reducing the falling and screening speed of the fertilizer particles, so that the fertilizer particles have sufficient screening time to ensure the screening effect. Moreover, the rotating turbulence paddle 7 can stir the fertilizer particles falling along the baffle plate 6 to disperse the piled-up falling fertilizer, further maintaining the screening effect.

[0044] Refer to Figure 4 and Figure 5 , in the fertilizer particle screening device described in the embodiments of the present application, the output end of the driving motor 4 is fixedly connected with a rocker 41. One end of the rocker 41 is slidably connected with a pressing frame 42. The pressing frame 42 is arranged in an L-shaped structure, and the pressing frame 42 arranged in an L-shaped structure is fixedly connected with the main sieve hopper 3. The rocker 41 is composed of two slidably connected parts, a sleeve 43 and an extension rod 44. The sleeve 43 is fixedly connected with the output end of the driving motor 4, the extension rod 44 is slidably matched with the pressing frame 42, and the sleeve 43 and the extension rod 44 are connected and limited by an adjusting screw 45.

[0045] In this fertilizer particle screening device, the driving motor 4 drives the rocker 41 to rotate. The rotating rocker 41 presses against the pressing frame 42, so that the pressing frame 42 pressed by the rotating rocker 41 drives the fixedly connected main sieve hopper 3 to swing reciprocally under the hinge action of the connecting rod, screening the fertilizer particles discharged from the hopper 2 by shaking. The sleeve 43 and the extension rod 44 are adjusted to expand and contract under the control of the adjusting screw 45, changing the rotation radius of the rocker 41 to adjust the swing amplitude of the main sieve hopper 3, thereby improving the use effect of the device for screening.

[0046] Working principle: When the driving motor 4 drives the rocker 41 to press against the pressing frame 42 to swing reciprocally, the reciprocally moving pressing frame 42 drives the fixedly connected main sieve hopper 3 to be limited in the power facility frame 1 to swing reciprocally, screening the fertilizer particles discharged from the hopper 2.

[0047] At this time, the turbulence paddle 7 rotatably connected in the reciprocally moving main sieve hopper 3 is meshed and driven with the tooth plate 12 on one side of the cross bar 11 fixedly installed in the power facility frame 1 under the action of the transmission gear 13, so that the turbulence paddle 7 under the action of the sprocket chain rotates to stir and disperse the fertilizer particles falling during screening for effective screening.
