Description

Technical Field

[0001] This utility model relates to the field of fertilizer granule screening and grading technology, specifically to a fertilizer granule screening and grading vibrating screen. Background Technology

[0002] Chemical fertilizer is a fertilizer made using chemical methods that contains one or more nutrients needed for crop growth. Fertilizers containing only one nutrient element with a clearly labeled content are called single-element fertilizers, such as nitrogen, phosphorus, and potassium fertilizers, as well as fertilizers containing minor macroelements and microelements. Fertilizers containing two or three of the three nutrients—nitrogen, phosphorus, and potassium—with their content clearly labeled are called compound fertilizers or mixed fertilizers. The solubility of the effective components of a fertilizer in water is usually a standard for measuring its effectiveness. There are many types of chemical fertilizers, with significant differences in properties and application methods. In the production process of compound fertilizers, it is often necessary to screen the already formed granules to remove larger or smaller particles. This requires the use of a fertilizer granule screening and grading vibrating screen.

[0003] However, existing fertilizer granule screening and grading vibrating screens have mesh openings at the top, requiring fertilizer to pass through for screening. As the screen vibrates, some fertilizer granules, slightly larger than the mesh openings, get stuck at the top of the screen due to the combined effects of gravity and vibration, causing blockage and affecting the subsequent screening efficiency. Therefore, this method does not meet current requirements. To address this, we propose a fertilizer granule screening and grading vibrating screen. Utility Model Content

[0004] The purpose of this invention is to provide a fertilizer granule screening and grading vibrating screen to solve the problem mentioned in the background art: when using a fertilizer granule screening and grading vibrating screen, because the upper part of the vibrating screen has mesh holes, fertilizer needs to pass through the vibrating screen to complete the screening. As the vibrating screen vibrates, under the combined action of gravity and vibration, some fertilizer granules that are slightly larger than the mesh holes of the vibrating screen will get stuck at the upper part of the vibrating screen, causing the vibrating screen to become clogged and affecting the subsequent screening efficiency of the device for fertilizer granules.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fertilizer granule screening and grading vibrating screen, including a main support frame:

[0006] A grading sieve plate is rotatably mounted inside the main support via bearings. A surrounding plate is fixedly mounted on the upper end of the grading sieve plate, and a vibrating support is fixedly mounted on the lower end of the grading sieve plate. A vibrating motor is fixedly mounted inside the vibrating support, and a diversion plate is fixedly mounted on the upper end of the vibrating support.

[0007] A guide plate is welded to one side of the main support. A limit block is fixedly installed on the front end face of the main support. A drive rack is longitudinally slidably connected inside the limit block through a slot. A connecting rod is fixedly installed on the upper end of the drive rack. An installation plate is fixedly installed on one side of the upper end of the front end face of the main support. An electric telescopic rod is fixedly installed on the lower end of the installation plate. The telescopic end of the electric telescopic rod is fixedly connected to the connecting rod. A rotating gear is fixedly installed on the front end face of the grading screen plate. The rotating gear meshes with the drive rack.

[0008] Preferably, a support base is installed at the lower end of the main support frame, and the support base is welded to the main support frame.

[0009] Preferably, a bearing platform is installed on one side of both the support base and the main support, and the bearing platform is welded to both the support base and the main support.

[0010] Preferably, a graded collection box is placed on the upper end of the carrying platform.

[0011] Preferably, a feeding bracket is installed at the upper end of the main support, and the feeding bracket is welded to the main support.

[0012] Preferably, a controller is installed on the other side of the main support, and the controller is connected to the main support by screws.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, by installing a grading screen plate and rotating it inside the main support, allows the grading screen plate to rotate when fertilizer particles clog the upper part of the grading screen plate. This causes the side of the grading screen plate that is screening fertilizer particles to tilt downwards, so that the fertilizer particles are shaken out of the grading screen plate under the combined action of gravity and vibration motor. This avoids fertilizer particles clogging the grading screen plate for a long time, ensures that the grading screen plate can quickly screen fertilizer particles, and ensures the screening efficiency of the device for fertilizer particles.

[0015] 2. This utility model, by installing a drive rack and pinion, can drive three grading screens to rotate synchronously in conjunction with a rotating gear. This makes it easy for operators to adjust the tilt angle of the grading screens, facilitates the discharge of fertilizer particles after sieving, and reduces the difficulty of using the device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1-4 One embodiment of this utility model is a fertilizer granule screening and grading vibrating screen, including a main support 1:

[0023] The grading screen plate 14 is rotatably mounted inside the main support 1 via bearings. When fertilizer particles clog the upper end of the grading screen plate 14, the grading screen plate 14 can rotate, causing the side of the grading screen plate 14 that is screening fertilizer particles to tilt downwards. Under the combined action of gravity and the vibration motor 18, the fertilizer particles are shaken out of the grading screen plate 14, thereby preventing fertilizer particles from clogging the grading screen plate 14 for a long time, ensuring that the grading screen plate 14 can quickly screen fertilizer particles, and ensuring the screening efficiency of the device for fertilizer particles. A surrounding plate 15 is fixedly installed at the upper end of the grading screen plate 14, and a vibration bracket 16 is fixedly installed at the lower end of the grading screen plate 14. A vibration motor 18 is fixedly installed inside the vibration bracket 16, and a diversion plate 17 is fixedly installed at the upper end of the vibration bracket 16.

[0024] A guide plate 5 is welded to one side of the main support 1. A limit block 8 is fixedly installed on the front end face of the main support 1. A drive rack 9 is longitudinally slidably connected inside the limit block 8 through a slot. The drive rack 9 is installed so that it can drive the three grading screen plates 14 to rotate synchronously in conjunction with the rotating gear 7. This makes it easy for the operator to adjust the tilt angle of the grading screen plates 14, and facilitates the discharge of fertilizer granules after screening, thus reducing the difficulty of using the device. A connecting rod 10 is fixedly installed on the upper end of the drive rack 9. An installation plate 11 is fixedly installed on one side of the upper end of the front end face of the main support 1. An electric telescopic rod 12 is fixedly installed on the lower end of the installation plate 11. The telescopic end of the electric telescopic rod 12 is fixedly connected to the connecting rod 10. A rotating gear 7 is fixedly installed on the front end face of the grading screen plate 14. The rotating gear 7 meshes with the drive rack 9.

[0025] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The main support 1 has a support base 2 installed at its lower end, which is welded to the main support 1. Both the support base 2 and the main support 1 have a bearing platform 3 installed on one side. The bearing platform 3 facilitates the placement of the grading collection box 4 by the staff, allowing the grading collection box 4 to collect the graded fertilizer granules, making the device more user-friendly. The bearing platform 3 is welded to both the support base 2 and the main support 1. The grading collection box 4 is placed on the upper end of the bearing platform 3. The main support 1 has a feeding bracket 6 installed on its upper end, which is welded to the main support 1. The other side of the main support 1 has a controller 13 installed, which is connected to the main support 1 by screws.

[0026] Working Principle: During operation, the operator feeds fertilizer granules into the device through the feed support 6. The granules fall onto the top grading screen 14. The vibrating motor 18 then starts, causing the grading screen 14 to vibrate and screen the fertilizer granules. The screened granules fall onto the top of the middle grading screen 14, where they are screened again. The screened granules then fall onto the top of the bottom grading screen 14, where they are screened again. Next, the electric telescopic rod 12 moves the connecting rod 10 and the drive rack 9 downwards, causing the drive rack 9 to rotate the rotating gear 7 and the grading screen 14 counterclockwise by 15 degrees. This causes the screened fertilizer granules to fall onto the guide plate 5 and be discharged from the device. When fertilizer granules clog the grading screen 14, the electric telescopic rod 12 extends, causing the grading screen 14 to rotate clockwise. The device rotates 130 degrees, and then the vibrating motor 18 vibrates, causing the blocked fertilizer particles to be discharged from the top of the grading screen plate 14 under the combined action of gravity and vibration. The grading screen plate 14 is installed inside the main support 1 and rotated. When fertilizer particles block the top of the grading screen plate 14, the grading screen plate 14 can rotate, so that the side of the grading screen plate 14 that is screening fertilizer particles is tilted downwards. Under the combined action of gravity and the vibrating motor 18, the fertilizer particles are shaken out of the grading screen plate 14, thereby avoiding fertilizer particles blocking the grading screen plate 14 for a long time, ensuring that the grading screen plate 14 can quickly screen fertilizer particles, and ensuring the screening efficiency of the device. The installation of the drive rack 9, which works with the rotating gear 7, can drive the three grading screen plates 14 to rotate synchronously, making it easy for the operator to adjust the tilt angle of the grading screen plate 14, facilitating the discharge of the screened fertilizer particles from the device, and reducing the difficulty of using the device.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
