Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a high-efficiency fertilizer screening device. Background Art

[0002] Chemical fertilizers, commonly known as fertilizers, are fertilizers made by chemical methods that contain one or more nutrients required for the growth of crops. The macronutrients nitrogen, phosphorus, and potassium in the soil usually cannot meet the needs of crop growth and need to be supplemented by chemical fertilizers. During the production process, chemical fertilizers need to be dried and screened after being granulated by a granulator.

[0003] For example, the authorization announcement number "CN207857311U" is named a fertilizer screening device. Although wind screening is adopted, fertilizers of different sizes will be blown to different collection areas by wind. Compared with centrifugal screening, this screening mode has high accuracy and is relatively simple. However, the existing fertilizer screening device uses wind to separate and screen fertilizers of different sizes. However, most of the fertilizers used in agriculture are round particles of different sizes. The fertilizers themselves have a certain weight, so the power of being blown and screened by wind during the falling process is relatively limited. At the same time, the fertilizers are collected and screened in three side-by-side collection boxes. Since light fertilizers will fly farther and fall into the collection box on the far left, it is difficult for the operator to control the movement trajectory of the fertilizer after it falls and is blown. Light and small fertilizers may also fall into the nearby collection box, and heavy and large fertilizers may also fall into the farther collection box. This makes the fertilizers that have been screened finally need to be manually selected for a second time, which is not only troublesome and time-consuming, but also increases the additional engineering workload, affecting the low working efficiency of the fertilizer screening device.

DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings:

[0024] See also Figure 1-6 A high-efficiency fertilizer screening device comprises a base 1, a fertilizer collecting box 2 and a fertilizer screening box 3, wherein the fertilizer collecting box 2 is fixedly installed above the base 1, the fertilizer screening box 3 is fixedly connected to the top of the fertilizer collecting box 2, and a high-efficiency fertilizer screening structure 5 is arranged inside the fertilizer screening box 3, the high-efficiency fertilizer screening structure 5 comprises a feeding hole 51, a lower slide plate 52 and a cylinder 55, and the feeding hole 51 is fixedly opened on one side of the top of the fertilizer screening box 3;

[0025] The lower slide plate 52 is movably connected to the lower part of the fertilizer screening box 3. A plurality of screening nets 53 are fixedly connected to the inner side of the lower slide plate 52. Three screening nets 53 are arranged in sequence from top to bottom along the lower slide plate 52. The meshes of the screening nets 53 are gradually enlarged. In this way, the operator pours the produced fertilizer into the feeding hole 51, and then the fertilizer particles falling from the feeding hole 51 will slide downward on the lower slide plate 52. During the sliding process, the fertilizer passing through the lower screening plate 53 will fall according to its diameter. A plurality of baffles 54 are fixedly connected to the lower ends of the plurality of screening nets 53.

[0026] The baffle 54 plays a role in guiding and blocking the falling fertilizer particles. A plurality of cylinders 55 are fixedly connected to the inner top of the fertilizer screening box 3. The lower ends of the plurality of cylinders 55 are fixedly connected with impact hammers 56. During the sliding process of the fertilizer, the power supply is connected to start the plurality of cylinders 55. The cylinders 55 will push the impact hammers 56 at the lower ends to hit the upper part of the lower slide plate 52 one by one. The impacting impact hammers 56 will use inertia to shake the fertilizer remaining on the upper part of the lower slide plate 52 to the lower part, thereby accelerating the fertilizer screening speed. The lower end of the feeding hole 51 is arranged opposite to the upper part of one end of the lower slide plate 52. The impact hammers 56 are made of a stainless steel metal sphere with a spherical end, which can hit the lower slide plate 52 with force to achieve the effect of promoting the sliding and screening of the fertilizer. The lower ends of the plurality of impact hammers 56 are movably connected to the upper part of the lower slide plate 52.

[0027] Three screening nets 53 are arranged along the lower slide plate 52 from top to bottom, and the mesh of the screening net 53 is gradually enlarged, so that the operator pours the produced fertilizer into the feeding hole 51, and then the fertilizer particles falling from the feeding hole 51 will slide downward on the top of the lower slide plate 52. During the sliding process, the fertilizer passing through the lower screening plate 53 will fall according to its diameter. The baffle 54 plays a role in guiding and blocking the falling fertilizer particles. During the sliding of the fertilizer, the power supply is connected to start multiple cylinders 55. The cylinder 55 will push the impact hammer 56 at the lower end to hit the top of the lower slide plate 52 one by one. In this way, the impacting impact hammer 56 will use inertia to shake the fertilizer remaining on the top of the lower slide plate 52 to the bottom, thereby accelerating the fertilizer screening speed, and directly screening the fertilizer by sliding down, reducing the excessive amount of fertilizer misscreened in the process and wind screening, and improving the working efficiency of the high-efficiency fertilizer screening device.

The tops of the three collecting troughs 71 correspond to the screening nets 53 one by one, so the screened fertilizer will directly fall down into the collecting trough 71. Multiple connecting blocks 73 are fixedly connected to both sides of the tops of the multiple vertical rods 72. Multiple collecting troughs 71 are fixedly connected to the other ends of the multiple connecting blocks 73. The tops of the multiple collecting troughs 71 are arranged opposite to the bottoms of the multiple screening nets 53.

The discharge port 63 is fixedly opened on the side wall of the fertilizer screening box 3, and the guide plate 61 is fixedly connected below the discharge port 63. The diagonal support plate 62 supports and fixes the guide plate 61 to one side of the fertilizer screening box 3.
