Description

Technical Field

[0001] This utility model relates to the field of fertilizer processing technology, specifically to a fertilizer raw material particle screening vibration device. Background Technology

[0002] Fertilizers play a vital role in agricultural production. With the rapid development of agriculture in my country, the standards and requirements for fertilizers are also increasing. Fertilizer vibrating screens are adaptable to different types, properties, and particle sizes of fertilizers used in the industry, and have a wide range of applications.

[0003] For example, a fertilizer screening device with authorization announcement number "CN220444360U" uses a rotating drum to drive a stirring column, which agitates the fertilizer particles to ensure thorough heating and drying. This facilitates the drying of moisture within the fertilizer before screening, effectively preventing clumping and sticking caused by external humidity, thus improving the screening efficiency. However, this device is not convenient for individual control of different screens. When only two screenings of the fertilizer raw material are needed, the device cannot complete the process and still performs three screenings, reducing its adjustability and making it inconvenient to use.

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] See attached document Figure 1-6 In this embodiment, a fertilizer raw material particle screening vibration device includes a housing 1 and a partition 5. The partition 5 is fixedly connected to the inner wall of the housing 1. A through hole is opened at the lower end of the housing 1. Support legs are symmetrically fixedly connected to the lower end of the housing 1. The inner wall of the housing 1 is rotatably connected to both ends of a rotating rod 6 through bearings. The upper end of the rotating rod 6 is fixedly connected to the output shaft of a servo motor 7. The servo motor 7 can meet the working requirements according to actual needs. The servo motor 7 is fixedly connected to the housing 1 through a motor frame. Multiple sets of transmission devices 2 are provided on the outer wall of the rotating rod 6. A screening device 9 is provided on the inner wall of the housing 1.

[0022] The outer wall of the sleeve 205 fits into the through hole on the surface of the partition 5. One end of the sleeve 205 passes through the partition 5. The upper end of the box 1 is fixedly connected to the funnel 8. The right end of the box 1 is movably connected to multiple sliding doors 3 through multiple hinges. There are three sliding doors 3. The outer wall of each sliding door 3 is fixedly connected to a handle 4. One end of the frame 902 fits into multiple sleeves 205. An opening is opened at the left end of the box 1.

[0023] The transmission device 2 includes a push rod 201 and a ring 203. The inner wall of the ring 203 is slidably connected to the rotating rod 6. Multiple push rods 201 are fixedly connected to the outer wall of the ring 203. There are four push rods 201. The outer wall of one push rod 201 is in contact with the sleeve 205. The inner wall of the sleeve 205 is slidably connected to the slide rod 204. One end of the slide rod 204 is fixedly connected to the inner wall of the housing 1. The sleeve 205 and the housing 1 are respectively fixedly connected to both ends of the first spring 202. The elastic coefficient of the first spring 202 is determined according to actual needs and meets the working requirements. A vertical plate 206 is fixedly connected to the upper end of the ring 203. The vertical plate 206 is threadedly connected to the bolt 207 through a threaded through hole on its surface. One end of the bolt 207 is inserted into the rotating rod 6.

[0024] The screening device 9 includes sliders 901 and frames 902. Multiple sliders 901 are slidably connected to the inner wall of the housing 1. Multiple sliders 901 are slidably connected to straight rods 905 through through holes on their surfaces. Both ends of the straight rods 905 are fixedly connected to the inner wall of the housing 1. One end of each slider 901 is fixedly connected to a number of frames 902. There are three frames 902. A second spring 903 is fixedly connected to the outer wall of each slider 901. The elastic coefficient of the second spring 903 is determined according to actual needs to meet the working requirements. One end of the second spring 903 is fixedly connected to the housing 1. Screens 904 are fixedly connected to the inner wall of each frame 902. The three sets of screens 904 are all made of woven steel wire. The mesh size of the three sets of screens 904 decreases from top to bottom. The specific mesh size can be selected according to actual needs.

[0025] Working principle:

[0026] When vibrating to screen fertilizer raw material particles:

[0027] During the screening process, the collected containers (such as...) Figure 2 The fertilizer raw materials are arranged as shown in the figure. The operator adds the fertilizer raw materials into the box 1 through the funnel 8, so that the fertilizer raw materials fall onto the surface of the screen 904 at the top (the length of the screen 904 can be designed according to the actual situation. When a large amount of fertilizer raw materials are introduced at one time, the length of the screen 904 can be increased, and vice versa). The servo motor 7 is controlled to work, so that the output shaft of the servo motor 7 rotates and drives the rotating rod 6 to rotate synchronously. The rotating rod 6 drives multiple rings 203 to rotate synchronously. The rings 203 drive four push rods 201 to rotate synchronously. The four push rods 201 can push the sleeve 205 in sequence (the end of the push rod 201 can also be set to be arc-shaped to make it more smooth under high speed). The sleeve 205 can continuously stretch the first spring 202 to realize the reciprocating motion of the frame 902.

[0028] The three frames 902 are compressed by twelve sliders 901, which in turn compress the twelve second springs 903, so that the frames 902 can reciprocate and vibrate to screen the fertilizer particles. After being screened by the uppermost screen 904, the particles will fall onto the surface of the middle screen 904 and finally fall onto the lowermost screen 904. The screened particles 904 can be transported out from the left end of the box 1. After the lowermost screen 904 has finished screening, it will fall through the opening at the bottom of the box 1.

[0029] Adjustment process:

[0030] When the number of screenings needs to be reduced, the operator opens the corresponding sliding door 3, rotates the corresponding bolt 207 so that the bolt 207 is no longer connected to the rotating rod 6, pushes the ring 203 upward so that the ring 203 moves upward, and then rotates the bolt 207 in the opposite direction so that the bolt 207 is connected to the rotating rod 6. The ring 203 and the sleeve 205 are misaligned. When the rotating rod 6 rotates, it drives the push plate 201 so that it will not push the sleeve 205 and its corresponding screen 904 to vibrate, making the adjustment of this device more convenient.
