[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model. Embodiment 1

[0040] As Figures 1 - 3 shown, it is a schematic structural diagram of the feeding mechanism in this embodiment. The feeding mechanism in this embodiment is used in the nitrogen-potassium fertilizer production process to transport raw materials to the target process for the production and processing of nitrogen-potassium fertilizer. The feeding mechanism in this embodiment includes a frame 100. Rotating rollers 101 are rotatably installed at both ends of the frame 100, and a conveyor belt 102 is wound around the rotating rollers 101. In addition, as Figure 1 shown, in this embodiment, a driver 103 is further provided on one side of the frame 100. As Figure 6 shown, a driving roller 104 is rotatably installed at the bottom of the frame 100. The driver 103 is connected to the driving roller 104. By the operation of the driver 103, the driving roller 104 can be driven to rotate. In this embodiment, the conveyor belt 102 is wound around the rotating roller 101 and the driving roller 104. In this embodiment, by the operation of the driver 103 to drive the driving roller 104 to rotate, the conveyor belt 102 is driven to move to facilitate the transportation of raw materials.

[0041] It should be noted that, as Figures 1 - 3 shown, the feeding mechanism in this embodiment further includes a protection component 200. The protection component 200 is arranged on the surface of the frame 100 and on both sides of the conveyor belt 102 on the surface of the frame 100. The protection component 200 is used to protect the materials on the conveyor belt 102 to avoid the problem of materials falling from both sides of the conveyor belt 102.

[0042] As Figure 1 and Figure 4 shown, the protection component 200 in this embodiment includes protection side plates 201, and a fixing rod 202 is fixedly installed on the frame 100. The protection side plates 201 are rotatably connected to the fixing rod 202. In this embodiment, the protection side plates 201 are symmetrically arranged on the surface of the frame 100 and on both sides of the conveyor belt 102. In this embodiment, when the conveyor belt 102 transports materials, the protection side plates 201 are located on both sides of the conveyor belt 102 to protect the materials to avoid the problem of materials falling from both sides of the conveyor belt 102 during transportation.

[0043] In addition, as Figure 4As shown in the figure, in this embodiment, in order to adjust the size of the space between the protective side plates 201, the protective component 200 in this embodiment further includes a pusher 203. One end of the pusher 203 in this embodiment is rotatably installed on the frame 100, and the other end is rotatably installed on the side wall of the protective side plate 201. In this embodiment, when the pusher 203 works, it can push the protective side plate 201 to rotate relative to the fixed rod 202, so that the size of the space between the symmetrically arranged protective side plates 201 can be adjusted, facilitating the conveying of materials.

[0044] In this embodiment, when it is necessary to adjust the size of the space between the protective side plates 201 according to the usage amount of the material, the pusher 203 works to drive the protective side plate 201 to rotate relative to the fixed rod 202. Therefore, the size of the space between the symmetrically arranged protective side plates 201 can be adjusted to facilitate real-time adjustment according to the conveying amount of the material, ensuring the transportation of the material. Embodiment 2

[0045] As Figure 1 , Figure 2 and Figures 5 - 8 As shown, the difference between this embodiment and Embodiment 1 is that the nitrogen-potassium fertilizer feeding mechanism in this embodiment further includes a tensioning component 300. The tensioning component 300 in this embodiment is used to tension the conveyor belt 102 to avoid the problem that the conveyor belt 102 becomes loose and cannot convey materials.

[0046] In this embodiment, as Figure 7 and Figure 8 shown, a tensioning component 300 is installed on the frame 100. The tensioning component 300 includes an adjusting roller 301 installed below the frame 100. The adjusting roller 301 is arranged in parallel with the driving roller 104. The conveyor belt 102 is wound around the adjusting roller 301, the driving roller 104, and the rotating roller 101. In this embodiment, when the distance between the adjusting roller 301 and the driving roller 104 is adjusted, the conveyor belt 102 can be tightened, making the conveyor belt 102 in a taut state to facilitate the conveying of materials.

[0047] As Figure 8 shown, in this embodiment, an opening groove 100a is formed on the side wall of the frame 100. At both ends of the adjusting roller 301 in this embodiment, connecting rods 302 are rotatably installed. Threads are distributed on the connecting rods 302, and fixing ears are provided on the frame 100. The connecting rods 302 pass through the fixing ears and are locked by nuts. In this embodiment, when it is necessary to adjust the tension of the conveyor belt 102, the nuts are rotated to drive the connecting rods 302 to drive the adjusting roller 301 to move along the length direction of the opening groove 100a, so as to adjust the distance between the adjusting roller 301 and the driving roller 104, facilitating the tightening of the conveyor belt 102, and enabling the conveyor belt 102 to convey materials in a taut state. Example 3

[0048] As Figure 9 and Figure 10 shown, the difference between this embodiment and Embodiment 1 and Embodiment 2 is also that the nitrogen and potassium fertilizer production feeding mechanism in this embodiment further includes a scraping component 400 for scraping the materials on the conveyor belt 102. The scraping component 400 in this embodiment includes a rotating shaft 401 rotatably installed below the frame 100. The surface of the rotating shaft 401 is distributed with spiral plates 402 in a spiral manner. And, the rotating shaft 401 is connected to the rotating roller 101 through a transmission belt. In this embodiment, when the driver 103 drives the conveyor belt 102 to rotate, it can drive the rotating roller 101 to rotate. When the rotating roller 101 rotates, it can drive the rotating shaft 401 and the spiral plates 402 to rotate. The spiral plates 402 abut against the conveyor belt 102. The rotation of the spiral plates 402 can scrape the materials on the surface of the conveyor belt 102, avoiding the adhesion of materials on the surface of the conveyor belt 102.

[0049] It should be noted that the spiral plates 402 in this embodiment are installed on the rotating shaft 401 as movable scrapers. The scrapers can scrape the materials attached to the conveyor belt 102 when following the rotation of the rotating shaft 401. The scrapers in this embodiment include but are not limited to the spiral plates 402. Other structures of scrapers located on the rotating shaft 401 that can scrape the materials on the conveyor belt 102 when following the rotation of the rotating shaft 401 can be applied in this embodiment.

[0050] Working principle: In the present utility model, the driver 103 works to drive the driving roller 104 to rotate so as to drive the conveyor belt 102 to move. When the conveyor belt 102 rotates, it conveys the materials on its surface to facilitate the conveyance of the materials to the designated process. And, the protective side plates 201 at the top of the frame 100 block the materials, avoiding the falling of the materials from both sides of the conveyor belt 102. In addition, when the conveyor belt 102 becomes loose, the nut is rotated to drive the connecting rod 302 to drive the adjusting roller 301 to move, so as to adjust the distance between the adjusting roller 301 and the driving roller 104, thereby tightening the conveyor belt 102 to facilitate the conveyance of the materials. And when the conveyor belt 102 rotates, it can drive the rotating rollers 101 at both ends of the frame 100 to rotate. A rotating shaft 401 is further provided at the bottom of the frame 100. The rotation of the rotating roller 101 drives the rotating shaft 401 to rotate through a transmission belt. The spiral plates 402 are provided on the rotating shaft 401. The spiral plates 402 abut against the conveyor belt 102. The rotation of the spiral plates 402 can scrape the materials on the conveyor belt 102, avoiding the adhesion of materials on the conveyor belt 102.

[0051] The control method of the present utility model is automatically controlled by a controller. The control circuit of the controller can be realized by simple programming by those skilled in the art. The provision of power supply also belongs to the common general knowledge in the art. Moreover, the present utility model is mainly used to protect mechanical devices. Therefore, the control method and circuit connection of the present utility model will not be further explained in detail.
