DETAILED DESCRIPTION

[0023] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figures 1 to 5 As shown, an embodiment of the utility model proposes a feeding device for fertilizer production, which is used to feed fertilizer during the fertilizer production process to input the fertilizer into the production equipment and screen the fertilizer during the feeding process to prevent fertilizer with unqualified particle size from entering the production equipment and affecting product quality.

[0025] Please refer to Figure 1 , Figure 2 and Figure 3The feeding device for fertilizer production comprises a cover body 1 and a platen 2 which are arranged at intervals, wherein the cover body 1 is connected to the feeding end of the production equipment, and the platen 2 can be fixed on the production equipment. A feeding hopper 11 which is connected to the cover body 1 is provided on the cover body 1, and a screen 3 is provided in the narrow body and the screen 3 is located below the feeding hopper 11. After the fertilizer is poured into the cover body 1 from the feeding hopper 11, it falls on the screen 3 under the action of gravity, and the fertilizer can be screened; an air guide pipe 4 is also provided on the cover body 1. The air guide pipe 4 extends into the cover body 1, and a plurality of first nozzles 41 are arranged at intervals on the portion of the air guide pipe 4 located in the cover body 1, and the air outlet ends of the first nozzles 41 are all facing the screen 3, and the table 2 is provided with a fixed pipe sleeve 5 connected to the air guide pipe 4, and the fixed pipe sleeve 5 is provided with an air inlet pipe 51 connected to the fixed pipe sleeve 5, and the air inlet pipe 51 is used to connect to an external compressed air source to input compressed air into the fixed pipe sleeve 5, and a rotatable movable pipe 6 is provided in the fixed pipe sleeve 5, so that The movable tube 6 is coaxially arranged with the fixed tube sleeve 5 and the movable tube 6 is in contact with the inner wall of the fixed tube sleeve 5. One end of the movable tube 6 is connected with the air guide tube 4. An opening 61 penetrating the movable tube 6 is provided on the portion of the movable tube 6 close to the connection between the fixed tube sleeve 5 and the air inlet pipe 51. A driving assembly 7 connected to the movable tube 6 in a transmission manner is further provided on the table 2. The driving assembly 7 is used to drive the movable tube 6 to rotate and connect the opening 61 to the air inlet pipe 51 or to The opening 61 is staggered with the air intake pipe 51. When the movable pipe 6 rotates to a position where the opening 61 is connected to the air intake pipe 51, the compressed air input from the connecting pipe 44 can reach each of the first nozzles 41 along the movable pipe 6, the fixed pipe sleeve 5 and the air guide pipe 4 and be ejected from the first nozzle 41. When the movable pipe 6 rotates to a position where the opening 61 is staggered with the air intake pipe 51, the connection between the movable pipe 6 and the air intake pipe 51 is disconnected and the compressed air is blocked from entering the air guide pipe 4.

[0026] Specifically, the operation steps of the feeding operation using the fertilizer production feeding device provided in this embodiment are as follows: first, the cover body 1 and the table 2, which are connected to each other, are installed at the production equipment and the driving component 7 is turned on, and the fertilizer is poured into the feeding hopper 11. After the fertilizer is poured into the feeding hopper 11, it falls on the screen 3 under the action of gravity for screening, and during the feeding process, the driving component 7 drives the movable pipe 6 to rotate continuously in the fixed pipe sleeve 5. When the movable pipe 6 rotates to the position where the opening 61 is connected to the air inlet pipe 51, the compressed air input from the air inlet pipe 51 flows along the movable pipe 6, the fixed pipe sleeve 5 and the air guide pipe 4 in sequence and reaches each of the first Nozzle 41, the airflow ejected from the first nozzle 41 acts on the screen 3, so that the fertilizer blocked in the mesh of the screen 3 passes through the screen 3, and blows the fertilizer retained on the screen 3 to move, thereby screening the retained fertilizer, and when the movable tube 6 rotates to a position where the opening 61 is staggered from the air inlet pipe 51, the connection between the movable tube 6 and the air inlet pipe 51 is disconnected and compressed air cannot be input into the first nozzle 41. At this time, the fertilizer poured into the feed hopper 11 naturally falls in the cover body 1 and is screened by the screen 3, reducing the rolling caused by the airflow during the falling process of the fertilizer, thereby shortening the retention time of the fertilizer in the cover body 1 and improving the feeding efficiency. That is, the feeding device for fertilizer production provided in this embodiment causes the first nozzle 41 to intermittently eject airflow through the rotation of the movable pipe, thereby ensuring normal screening of the fertilizer while preventing the screen 3 from being blocked, avoiding the screen 3 from vibrating and making noise or colliding with other parts, thereby reducing noise pollution, which is beneficial to extending the service life of the equipment, and can ensure that the fertilizer is effectively screened during the feeding process and improve product quality.

[0027] like Figure 2 and Figure 4 As shown, in this embodiment, a protruding mounting portion 12 is provided on the inner wall of the cover body 1, a threaded hole 13 is provided on the mounting portion 12, and a mounting hole aligned with the threaded hole 13 is provided on the screen 3. The mounting portion 12 is provided on the inner wall of the cover body 1 for mounting the screen 3, a plurality of threaded holes 13 are provided on the mounting portion 12, and the mounting holes aligned with the threaded holes 13 are provided on the edge of the screen 3. The screen 3 can be fixed on the cover body 1 by passing a threaded connector 14 through the mounting hole and cooperating with the threaded hole 13, ensuring a reliable connection between the screen 3 and the cover body 1, and the screen 3 can be replaced by rotating the connector 14 to remove the connector 14, which is convenient for maintenance of the feeding device for fertilizer production.

After the compressed air enters the air duct 4, part of the compressed air enters the second nozzle 42 along the duct and is ejected from the second nozzle 42, and the airflow ejected from the second nozzle 42 flows toward the connection between the cover body 1 and the feed hopper 11 and pushes the fertilizer retained at the connection between the cover body 1 and the feed hopper 11 to move, so as to prevent the fertilizer from accumulating at the connection between the cover body 1 and the feed hopper 11 and causing the feed hopper 11 to be blocked. At the same time, the airflow ejected from the second nozzle 42 can blow the dust generated in the cover body 1 during the feeding process away from the connection between the cover body 1 and the feed hopper 11, so as to prevent the dust from entering the feed hopper 11, thereby preventing the dust from spreading to the surrounding environment and causing pollution.

[0031] Please refer to Figure 2 and Figure 5 Two bearings 53 are arranged in the fixed sleeve 5 at intervals, and the two bearings 53 are respectively matched with the movable tube 6 and are respectively arranged near the two ends of the movable tube 6. Two bearings 53 are arranged in the fixed sleeve 5 near the two ends of the movable tube 6 to reduce the friction between the movable tube 6 and the fixed sleeve 5, so that the movable tube 6 can rotate smoothly in the fixed sleeve 5.

[0032] like Figure 2 and Figure 5 As shown, a mounting shaft 62 is provided at one end of the movable tube 6 and the mounting shaft 62 extends out of the fixed tube sleeve 5, a first gear 63 is provided on the mounting shaft 62, and the driving assembly 7 includes a motor 71 and a second gear 72 provided at the output end of the motor 71, and the second gear 72 is meshed with the first gear 63. The motor 71 drives the second gear 72 to rotate, and through the cooperation of the first gear 63 and the second gear 72, the power output by the motor 71 can be transmitted to the mounting shaft 62 and the movable tube 6 can be driven to rotate, and the motor 71 can control the rotation speed of the movable tube 6 to adjust the time interval of the first nozzle 41 spraying airflow, so as to prevent the first nozzle 41 from spraying air too frequently and causing the fertilizer to be retained on the screen 3, so as to facilitate the use of the feeding device for fertilizer production.

[0033] Specifically, the fixed sleeve 5 is further provided with a sealing ring 54 and an end cover 55, the sealing ring 54 is arranged around the mounting shaft 62, and the end cover 55 is fixedly connected to the fixed sleeve 5 and presses the sealing ring 54 onto the fixed sleeve 5. By arranging the sealing ring 54 on the fixed sleeve 5 and using the end cover 55 to press the sealing ring 54, the sealing performance of the fixed sleeve 5 is improved, and leakage of the gap between the movable pipe 6 and the fixed sleeve 5 is prevented during the transportation of compressed gas.

[0034] like Figure 1 and Figure 3 As shown, the table 2 is also provided with a mounting bracket 21, which is sleeved on the fixed pipe sleeve 5 and fixedly connected to the table 2. The mounting bracket 21 is provided on the table 2 for the fixed pipe sleeve 5 to be installed, so that the position of the fixed pipe sleeve 5 on the table 2 remains stable, and the fixed pipe sleeve 5 is prevented from shaking during the compressed gas input process, resulting in unstable cooperation between the driving assembly 7 and the movable pipe 6, which is beneficial to improving the stability of the feeding device for fertilizer production.

[0035] Please combine Figure 2 and Figure 3 The air inlet pipe 51 is provided with a connector 56, and the connector 56 is located at one end of the air inlet pipe 51 away from the fixed pipe sleeve 5.
