Description

Technical Field

[0001] This utility model relates to the field of compound fertilizer production technology, and in particular to a raw material crushing device for compound fertilizer production. Background Technology

[0002] The raw materials for compound fertilizers mainly include three categories: nitrogen, phosphorus, and potassium. These raw materials are processed through chemical reactions or physical mixing methods to produce fertilizers containing two or more of the main nutrients for crops: nitrogen, phosphorus, and potassium. The raw materials for compound fertilizers are based on the three major nutrients required by crops: nitrogen (N), phosphorus (P2O5), and potassium (K2O). Micronutrients can also be added to improve fertilizer efficiency. The production process of compound fertilizers is mainly divided into two categories: chemical synthesis and physical mixing. The raw materials are screened and ground to ensure uniform particle size and remove impurities, providing a foundation for subsequent mixing and granulation.

[0003] In the existing technology, compound fertilizer raw materials are crushed by a crushing device. After crushing, fine raw materials and dust are mixed in, requiring a filtration structure to separate the fine raw materials and dust from the uniformly sized compound fertilizer raw materials. However, the filtration structure of general crushing devices is fixed, and the fine raw materials and dust from the crushing process easily clog the filtration structure, affecting the filtration effect. Therefore, a raw material crushing device for compound fertilizer production is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a raw material crushing device for compound fertilizer production, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: It includes a device frame and supporting legs installed at the four corners of the bottom of the device frame. A concave frame is installed inside the device frame, and a placement frame is arranged between the concave frames. A filter plate is installed at the bottom of the placement frame. Connecting rods that are symmetrically arranged and rotatably connected to the concave frames are arranged on both sides of the inner surface of the concave frames. Semi-circular gears are installed on both connecting rods. Placement grooves are symmetrically arranged on the concave frames. A strip plate is provided at the bottom of each of the two placement grooves. A strip groove extends through the bottom of the placement groove of the concave frame. Fixing strips are symmetrically installed at the bottom of the strip plates, and toothed blocks are vertically arrayed on one of the fixing strips.

[0006] As a further technical solution of this utility model, a plurality of the tooth blocks mesh with a semi-circular gear, support rods are symmetrically installed on the strip plate, a support plate is installed at the top of the support rods, and limit rods are symmetrically installed at the top of the support plate.

[0007] As a further technical solution of this utility model, sealing strips are installed around the four sides of the placement frame, and placement strips are symmetrically installed at the top of the placement frame. Each of the two placement strips is symmetrically provided with a limiting hole that matches the limiting rod.

[0008] As a further technical solution of this utility model, the surface of the filter plate is uniformly provided with small filter holes of the same size, a frame door is hinged to the front of the device frame near the bottom, a drive motor is installed on one side of the device frame, and a crushing chamber is provided inside the device frame near the top.

[0009] As a further technical solution of this utility model, a transmission rod is rotatably connected inside one end of the concave frame, one end of the two connecting rods extends to the inside of one end of the concave frame and a first bevel gear is installed, and two second bevel gears are installed on the transmission rod.

[0010] As a further technical solution of this utility model, the two second bevel gears mesh with the two first bevel gears respectively, the power output end of the drive motor is connected to one end of the transmission rod, and a feed hopper is installed at the top of the device frame.

[0011] This utility model provides a raw material crushing device for compound fertilizer production, which has the following advantages compared with the prior art:

[0012] This design discloses a raw material crushing device for compound fertilizer production. Through a set of semi-circular gears, a strip plate, connecting rods, a fixed strip, and toothed blocks, a drive motor rotates a transmission rod. Two second bevel gears on the rotating rod mesh with the first bevel gear, causing two connecting rods to rotate synchronously in the same direction. The semi-circular gear meshes with the toothed blocks on the fixed strip, driving the strip plate to move upward within a concave frame. After the semi-circular gear rotates and separates from the toothed blocks, the strip plate moves downward within the concave frame, causing a placement frame to slide up and down within the concave frame. This up-and-down sliding of the placement frame allows for the screening of the crushed compound fertilizer raw materials, separating fine dust from the crushed materials. This design enables the screening of crushed compound fertilizer raw materials. The placement frame moves up and down with the strip plate, accelerating the screening speed and preventing the crushed compound fertilizer from clogging the filter holes on the filter plate.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution for a raw material crushing device for compound fertilizer production, including a device frame 1 and support legs 2 installed at the four corners of the bottom of the device frame 1. A feed hopper 4 is installed at the top of the device frame 1. A frame door 3 is hinged to the front of the device frame 1 near the bottom. A drive motor 5 is installed on one side of the device frame 1. A crushing chamber 6 is set inside the device frame 1 near the top. (The crushing chamber 6 is the core technology of the crushing device and is a mature existing technology. Its working principle will not be described in detail here.) The bottom of the crushing chamber 6 is located above the concave frame 7. The compound fertilizer raw material falls into the crushing chamber 6 through the feed hopper 4 and is crushed. The crushed compound fertilizer raw material falls onto the placement frame 8.

[0020] The device frame 1 contains a concave frame 7, with a placement frame 8 between the concave frames 7. A filter plate 9 is installed at the bottom of the placement frame 8. Connecting rods 12 are symmetrically arranged on both sides of the concave frame 7 and are rotatably connected to it. Semi-circular gears 13 are installed on both connecting rods 12. Placement slots are symmetrically arranged on the concave frame 7, and strip plates 14 are installed at the bottom of both placement slots. A strip groove runs through the bottom of the placement slot of the concave frame 7. Fixing strips 15 are symmetrically installed at the bottom of the strip plates 14. Tooth blocks 16 are vertically arrayed on one fixing strip 15, and multiple tooth blocks 16 mesh with semi-circular gears 13. Support rods 17 are symmetrically installed on the strip plates 14, and support plates 18 are installed at the top of the support rods 17. Limiting rods 19 are symmetrically installed at the top of the support plates 18. Sealing strips 10 are installed around the placement frame 8. The top of the 8 is symmetrically equipped with placement strips 11. Each of the two placement strips 11 is symmetrically provided with limiting holes that are compatible with the limiting rods 19. The placement strips 11 are placed into the placement grooves on the concave frame 7. The limiting holes on the two placement strips 11 correspond to the limiting rods 19. The placement strips 11 are sleeved on the two limiting rods 19, and the placement frame 8 is placed inside the concave frame 7. When the two connecting rods 12 rotate, the semi-circular gear 13 intermittently meshes with the tooth block 16 on a fixed strip 15, driving the strip plate 14 to move up and down on the concave frame 7. At the same time, it drives the placement frame 8 to move up and down reciprocally, so that the fine debris and dust of the crushed compound fertilizer raw material on the placement frame 8 are screened through the filter holes on the filter plate 9 and fall into the inside of the device frame 1. At the same time, the placement frame 8 moves up and down, which can prevent fine debris and dust from clogging the filter holes.

[0021] The surface of the filter plate 9 is uniformly provided with small filter holes of the same size. A transmission rod 21 is rotatably connected to one end of the concave frame 7. One end of the two connecting rods 12 extends to the inside of one end of the concave frame 7 and a first bevel gear 20 is installed. Two second bevel gears 22 are installed on the transmission rod 21. The two second bevel gears 22 mesh with the two first bevel gears 20 respectively. The power output end of the drive motor 5 is connected to one end of the transmission rod 21. When the drive motor 5 is powered on, it drives the transmission rod 21 to rotate. The two second bevel gears 22 on the transmission rod 21 mesh with the two first bevel gears 20, driving the two connecting rods 12 to rotate synchronously.

[0022] The working principle of this utility model is as follows: When the frame door 3 is opened, the limiting holes on the two placement strips 11 correspond to the limiting rods 19. The placement strips 11 are then fitted over the two limiting rods 19. The placement frame 8 is placed inside the concave frame 7. The frame door 3 is closed, and the compound fertilizer raw material falls into the crushing chamber 6 through the feed hopper 4. The compound fertilizer raw material is then crushed. After crushing, the compound fertilizer raw material falls onto the placement frame 8, and the placement strips 11 are placed into the placement slots on the concave frame 7. The drive motor 5 is powered on and drives the transmission rod 21 to rotate. The two second bevel teeth on the transmission rod 21... Wheel 22 meshes with two first bevel gears 20, driving two connecting rods 12 to rotate synchronously. When the two connecting rods 12 rotate, the semi-circular gear 13 intermittently meshes with the tooth block 16 on a fixed strip 15, driving the strip plate 14 to move up and down on the concave frame 7, and at the same time driving the placement frame 8 to move up and down reciprocally, so that the fine debris and dust of the crushed compound fertilizer raw material on the placement frame 8 passes through the filter holes on the filter plate 9 and falls into the inside of the device frame 1. At the same time, the placement frame 8 moves up and down, which can prevent fine debris and dust from clogging the filter holes.
