Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fertilizer screening, in particular to a granular fertilizer screening device. Background Art
[0002] Fertilizer refers to a type of substance that can provide one or more essential nutrients for plants to improve soil properties and increase soil fertility levels. It is one of the material bases of agricultural production. Fertilizer usually needs to be screened during production and processing, so special screening devices must be used.
[0003] At present, the most commonly used screening device for screening granular fertilizers is a vibrating screening device. After the fertilizer particles are poured onto the screen surface of the screening device, particles smaller than the mesh size of the screen pass through the mesh size and fall down, while particles larger than the mesh size are discharged along one side of the screen. However, the mesh size of a screening device is usually fixed, and it cannot be used for screening fertilizers of different specifications. Other screening devices that can replace the screen are more troublesome when replacing the screen, and are not simple and convenient to use. Secondly, due to the limited length of the screen, the granular fertilizer moves on the screen surface for a relatively short time, and it cannot be guaranteed that the granular fertilizer is completely screened. The screening effect needs to be further improved. Therefore, the utility model proposes a granular fertilizer screening device. Utility Model Content

[0025] A vibration motor 10 is fixedly connected to the lower surface of the guide hopper 4 .
[0026] By starting the vibration motor 10, the screening tank 1 can be driven to vibrate, so that the granular fertilizer can be screened by the vibrating screening assembly 5.
[0027] The support assembly 2 includes a support cylinder 21 fixed to the lower surface of the screening tank 1, a support rod 22 is slidably connected to the bottom end of the support cylinder 21, and a first spring 23 is fixedly connected to the top end of the support rod 22 and the inner top wall of the support cylinder 21.
[0028] The first spring 23 of the support assembly 2 can amplify the vibration effect of the screening tank 1 .
[0029] The screening assembly 5 includes two rotating shafts 51 located at both ends of the screening tank 1. The two rotating shafts 51 are rotatably connected to the side walls of the screening tank 1 through bearings. A screen 52 is wound around the surfaces of the two rotating shafts 51. The screen 52 is divided into multiple screening areas. Each screening area is provided with screen holes 53 of different sizes. The two rotating shafts 51 are respectively fixedly connected to the corresponding driving ends of the servo motors 6.
[0030] By driving the screen 52 to rotate in the same direction through two servo motors 6, different screening areas can be located at the top, so that different sizes of screen holes 53 can be used to screen different types of fertilizer particles. There is no need to replace the screen 52, and it is simpler and more convenient to use.
[0031] The extrusion assembly 9 includes a fixed tube 91 fixed to the inner top wall of the top cover 8, a movable rod 92 is slidably connected inside the bottom end of the fixed tube 91, a second spring 93 is fixedly connected to the top end of the movable rod 92 and the inner top wall of the fixed tube 91, and the bottom ends of the multiple baffles 7 are in contact with the upper surface of the screen 52.
[0032] The baffle plate 7 can be pressed downward by the second spring 93 so that the bottom of the baffle plate 7 can always fit with the upper surface of the screen 52 , thereby preventing the fertilizer particles from passing through the bottom of the baffle plate 7 .
[0033] A plurality of baffles 7 are arranged in a staggered manner on the surface of the screen 52. By arranging a plurality of staggered baffles 7, the movement time of the fertilizer particles on the surface of the screen 52 can be increased, thereby improving the screening effect.

[0036] Working principle: When in use, one side of the guide plate 11 of the device can be raised. During screening, different screening areas of the screen 52 are selected according to the size of the fertilizer particles to be screened. The selection process is to start the two servo motors 6 to drive the screen 52 to rotate so that the corresponding screening area is located at the top, and then pour the granular fertilizer on the side with the guide plate 11. The fertilizer passes through the guide plate 11 and falls on the surface of the screen 52. At this time, the vibration motor 10 drives the entire device to vibrate, and the granular fertilizer will move along the screen 52 to the open side of the screening slot 1. In this process, the baffle 7 can increase the moving time of the granular fertilizer. The fertilizer smaller than the screen hole 53 falls along the guide hopper 4, and the fertilizer larger than the screen hole 53 is discharged from the open side of the screening slot 1.
