Description

Technical Field

[0001] This utility model relates to the field of potassium fertilizer processing technology, and more specifically, to a powder processing device. Background Technology

[0002] Potassium fertilizer is a fertilizer with potassium as its main nutrient. Common types include potassium chloride, potassium sulfate, potassium nitrate, and potassium dihydrogen phosphate. Potassium fertilizer can enhance crop resistance, making crops more resistant to drought, cold, lodging, and pests and diseases. It can also promote photosynthesis, improve photosynthetic efficiency, increase the accumulation of photosynthetic products, and thus improve the quality of agricultural products, making fruits sweeter and with better color. However, potassium fertilizer is highly hygroscopic and easily absorbs moisture from the air during storage, causing a water film to form on the surface of the granules, leading to clumping and adhesion. This clumping can affect its effectiveness, making it difficult to apply evenly, hindering the balanced absorption of potassium by crops and affecting growth and development. Furthermore, clumping slows down the dissolution rate of potassium fertilizer, resulting in a slower release of potassium and failing to meet the crop's needs in a timely manner.

[0003] To address the problem of potash fertilizer caking, a crushing device is typically used to break down the caking, damp potash fertilizer. Existing crushing devices usually consist of a feed cylinder and a grinding roller inside the cylinder. Raw material enters the cylinder through the feed inlet and falls to the bottom. The rotating grinding roller then crushes the caking material, restoring it to a loose granular state. However, during the crushing process, some of the raw material adheres to the bottom surface of the cylinder under the pressure of the grinding roller. Therefore, regular maintenance and cleaning of the cylinder's interior are required, significantly impacting the crushing efficiency of the device. Utility Model Content

[0024] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] See also Figures 1 to 5 As shown, this utility model provides a powder processing device, which includes: a powder cylinder 2, including a feed inlet 4 and a powder chamber 21 communicating with the feed inlet 4; and a powder assembly, including a mounting frame 14, a pressing roller 67, and a shovel structure 64. The mounting frame 14 is rotatably disposed in the powder chamber 21. The pressing roller 67 and the shovel structure 64 are both mounted on the mounting frame 14 and are arranged at intervals along the circumference of the mounting frame 14. The pressing roller 67 can rotate relative to the mounting frame 14 along its own central axis, and the shovel structure 64 can shovel up the material attached to the bottom wall of the powder chamber 21.

[0026] In this embodiment, the mounting frame 14 rotates, driving the crushing roller 67 and the shovel structure 64 mounted on it to rotate. The crushing roller 67 and the shovel structure 64 are arranged circumferentially at intervals, meaning that these two functional components can cooperate with each other during the material (e.g., potash fertilizer) crushing process to form a continuous crushing and cleaning process. The material enters the powder chamber 21 through the feed inlet 4. During the crushing process, the crushing roller 67 can roll and crush the material, while the shovel structure 64 can promptly shovel up the material adhering to the bottom wall of the powder chamber 21, keeping the bottom wall of the powder chamber 21 clean. This reduces the frequency of maintenance and cleaning of the powder chamber 21 and ensures crushing efficiency.

[0027] See also Figures 1 to 5 As shown, in one embodiment of the present invention, the powder device further includes a drive structure. The mounting frame 14 includes a first transmission structure 62, a first connecting arm 65, and a second connecting arm 63. The drive structure is drivenly connected to the first transmission structure 62. The first end of the first connecting arm 65 and the first end of the second connecting arm 63 are both connected to the first transmission structure 62. The first connecting arm 65 and the second connecting arm 63 are arranged at intervals along the circumference of the first transmission structure 62. The second end of the first connecting arm 65 is connected to the rolling roller 67, and the second end of the second connecting arm 63 is connected to the shovel structure 64.

[0028] In this embodiment, the drive structure is driven and connected to the first transmission structure 62, ensuring that power can be effectively transmitted from the drive source to the mounting frame 14. Its main function is to provide the necessary power for the crushing and shoveling processes. The first transmission structure 62, as a power transmission bridge between the drive structure and the first connecting arm 65 and the second connecting arm 63, can distribute power to the crushing roller 67 and the shoveling structure 64. The first connecting arm 65 and the second connecting arm 63 are arranged circumferentially along the first transmission structure 62. When the first connecting arm 65 drives the crushing roller 67 to crush the material, the shoveling structure 64 driven by the second connecting arm 63 can clean the crushing area, preventing the material from adhering to the bottom wall of the powder chamber 21, reducing the frequency of maintenance and cleaning, ensuring the cleanliness of the inside of the powder cylinder 2, and thus avoiding the problem of material adhesion affecting the subsequent crushing process.

[0029] See also Figures 1 to 5As shown, in one embodiment of the present invention, the powder device further includes a reset structure, which includes a sleeve 66, an elastic element 662, a connecting structure 663, and a slide rod 661 extending in the vertical direction. The sleeve 66 is connected to the second end of the first connecting arm 65. The elastic element 662 is installed inside the sleeve 66. The first end of the slide rod 661 passes through the sleeve 66 and can slide relative to the sleeve 66 in the vertical direction. The slide rod 661 is configured to form an anti-rotation fit with the sleeve 66. The elastic element 662 elastically abuts between the sleeve 66 and the slide rod 661. The second end of the slide rod 661 is connected to the connecting structure 663. The rolling roller 67 is rotatably connected to the connecting structure 663.

[0030] In this embodiment, the elastic element 662 elastically abuts against the sleeve 66 and the sliding rod 661. When the crushing roller 67 encounters a hard agglomerate during the crushing process, the sliding rod 661 moves vertically upward relative to the sleeve 66, compressing the elastic element 662. Once the crushing is finished, the elastic restoring force of the elastic element 662 pushes the sliding rod 661 and the crushing roller 67 connected to it back to their original positions, thereby ensuring the continuous and effective action of the crushing roller 67 on the material and improving the crushing efficiency. The sliding rod 661 and the sleeve 66 form an anti-rotation fit, meaning that the sliding rod 661 will not rotate during sliding, ensuring its linear movement in the vertical direction. This ensures that the crushing roller 67 rebounds accurately after encountering resistance, avoiding lateral deviation and maintaining the stability of the contact point between the crushing roller 67 and the material.

[0031] In one embodiment, the elastic element 662 is a spring.

[0032] In one embodiment, the slide rod 661 is a square rod, and the inner cavity 10 of the sleeve 66 is square. The slide rod 661 is adapted to the inner cavity 10 of the sleeve 66, so that the slide rod 661 cannot rotate relative to the sleeve 66, but can only slide in the vertical direction.

[0033] See also Figures 1 to 5 As shown, in one embodiment of the present invention, the connecting structure 663 includes an arc-shaped plate 6631 and two connecting plates 6632. The two connecting plates 6632 are respectively disposed at opposite ends of the arc-shaped plate 6631. The arc-shaped plate 6631 covers the top of the rolling roller 67, and the opening edge of the arc-shaped plate 6631 forms a scraping fit with the surface of the rolling roller 67.

[0034] In this embodiment, the arc-shaped plate 6631 is placed on top of the roller 67 and forms a scraping contact with the surface of the roller 67. When the roller 67 rotates, the opening edge of the arc-shaped plate 6631 can scrape off the material clumps adhering to the surface of the roller 67, which can effectively prevent the material from forming a hard shell on the surface of the roller 67 and ensure that the surface of the roller 67 remains clean after each rolling.

[0035] See also Figures 1 to 5 As shown, in one embodiment of the present invention, there are multiple rolling rollers 67, shovel structures 64, first connecting arms 65 and second connecting arms 63. The multiple rolling rollers 67 and multiple shovel structures 64 are arranged alternately along the circumference of the mounting frame 14. The multiple first connecting arms 65 are arranged in a one-to-one correspondence with the multiple rolling rollers 67, and the multiple second connecting arms 63 are arranged in a one-to-one correspondence with the multiple shovel structures 64.

[0036] In this embodiment, multiple crushing rollers 67 and multiple shovel structures 64 are arranged alternately along the circumference of the mounting frame 14, enabling continuous crushing of materials and continuous cleaning of the bottom wall of the crushing chamber. Multiple first connecting arms 65 correspond one-to-one with multiple crushing rollers 67, and multiple second connecting arms 63 correspond one-to-one with multiple shovel structures 64, allowing for more precise control of the movement of each component and achieving effective energy distribution.

[0037] See also Figures 1 to 5 As shown, in one embodiment of the present invention, the bottom surface of the shovel structure 64 is attached to the bottom surface of the powder cavity 21. The shovel structure 64 includes a shovel inclined surface 641, which forms an angle α with the bottom surface of the shovel structure 64. The value of α is in the range of 30°≤α≤45°.

[0038] The above settings facilitate the scooping of materials. When the scooping structure 64 rotates, the scooping inclined surface 641 can also guide the material to move outward along the scooping inclined surface 641, preventing the material from accumulating excessively at a certain position on the bottom wall of the powder chamber 21.

[0039] See also Figures 1 to 5 As shown, in one embodiment of the present invention, the powder device further includes a feeding cylinder 1, a powder cylinder 2 installed in the inner cavity 10 of the feeding cylinder 1, and a discharge port 68 communicating with the inner cavity 10 is provided on the side wall of the powder cylinder 2. The discharge port 68 is located on the moving path of the shovel structure 64, and a filter screen 681 is provided at the discharge port 68.

[0040] In this embodiment, the filter screen 681 allows fine particles or powder to pass through, while larger pieces of material are blocked. This ensures that only materials meeting a certain particle size standard can enter the inner cavity 10 of the feeding cylinder 1 through the discharge port 68. Since the discharge port 68 is located on the moving path of the shovel structure 64, the shovel structure 64 can not only clean the material on the bottom wall of the powder chamber 21 during rotation, but also directly guide the material to the discharge port 68. This design improves the flowability of the material, thereby accelerating the material feeding process and improving feeding efficiency. In addition, by setting the filter screen 681 at the discharge port 68, large pieces of material that have not been fully crushed can be prevented from clogging the discharge port 68 and the feeding cylinder 1, avoiding clogging problems that may occur during equipment operation.

[0041] In one embodiment, the filter screen 681 is fixedly installed at the discharge port 68 by a snap fastener.

[0042] In one embodiment, there are four discharge ports 68 and four filter screens 681. The four discharge ports 68 are evenly spaced along the circumference of the powder cylinder 2, and a filter screen 681 is provided at each discharge port 68.

[0043] In one embodiment, both the first connecting arm 65 and the second connecting arm 63 are L-shaped rods. The first transmission structure 62 is a cylindrical structure.

[0044] In one embodiment, there are two first connecting arms 65 and two second connecting arms 63. The two first connecting arms 65 and the two second connecting arms 63 are alternately arranged along the circumference of the first transmission structure 62. The two first connecting arms 65 are symmetrically arranged about the first transmission structure 62, and the two second connecting arms 63 are symmetrically arranged about the first transmission structure 62.

[0045] See also Figures 1 to 5 As shown, in one embodiment of the present invention, the powder device further includes a feeding component 7, which is disposed in the inner cavity 10. The feeding component 7 includes a second transmission structure 73 and a scraping structure 74. The second transmission structure 73 is driven and connected to the driving structure. One end of the scraping structure 74 is connected to the second transmission structure 73, and the other end of the scraping structure 74 is attached to the inner wall surface of the inner cavity 10.

[0046] In this embodiment, the scraper structure 74 is in contact with the inner wall of the inner cavity 10, which can ensure that material residues or adhesives on the inner wall are cleaned in time during the material falling process, avoiding material accumulation on the inner wall which may cause poor material feeding or even blockage, and ensuring the continuous operation of the powder device.

[0047] See also Figures 1 to 5As shown, in one embodiment of this utility model, the powder device further includes a first rotating rod 69, a second rotating rod 71, a first transmission belt 77, and a second transmission belt 721. A boss 9 is provided in the powder cavity 21. The first rotating rod 69 passes through the boss 9 and can rotate relative to the boss 9 along its own central axis. The driving structure includes a drive motor 61. A first pulley 11 is fixedly provided on the output shaft of the drive motor 61. A second pulley 12 is fixedly provided at the first end of the first rotating rod 69. The first pulley 11 is connected to the second pulley 12 through the first transmission belt 77. The first end of the second rotating rod 71 is rotatably connected to the bottom of the powder cylinder 2. A third pulley 13 is fixedly provided on the second rotating rod 71. A fourth pulley 72 is fixedly provided at the second end of the first rotating rod 69. The third pulley 13 is connected to the fourth pulley 72 through the second transmission belt 721. A first transmission structure 62 is fixedly provided on the output shaft of the drive motor 61 and located above the first pulley 11. A second transmission structure 73 is fixedly connected to the second rotating rod 71.

[0048] In this embodiment, the drive motor 61 is fixedly connected to the boss 9, and the boss 9 can support the drive motor 61. The output shaft of the drive motor 61 rotates, driving the first pulley 11 to rotate. The first pulley 11 drives the second pulley 12 to rotate via the first transmission belt 77, which in turn drives the first rotating rod 69 to rotate. The fourth pulley 72 rotates, driving the third pulley 13 to rotate via the second transmission belt 721, which in turn drives the second rotating rod 71 to rotate. The rotation of the second rotating rod 71 can then drive the second transmission structure 73 fixedly connected to it to rotate, thereby driving the scraping structure 74 to rotate, thus cleaning the material on the inner wall surface of the inner cavity 10.

[0049] It should be noted that the output shaft of the drive motor 61 of this application drives the first connecting arm and the second connecting arm to rotate clockwise and counterclockwise, thereby realizing the clockwise and counterclockwise rotation of the crushing roller and the shovel mechanism.

[0050] In one embodiment, the boss has two bearing seats spaced vertically apart, and each end of the first rotating rod 69 has a bearing. The two bearing seats correspond one-to-one with the two bearings, and the bearings are mounted on their respective bearing seats. With the above arrangement, the first rotating rod 69 can rotate relative to the boss 9 along its own central axis.

[0051] See also Figures 1 to 5 As shown, in one embodiment of the present invention, the feeding assembly 7 further includes a discharge pipe 5 extending in a vertical direction. The discharge pipe 5 is connected to the inner cavity 10. The second end of the second rotating rod 71 is provided with a propeller blade 76, which is located inside the discharge pipe 5 and is configured to be adapted to the discharge pipe 5.

[0052] In this embodiment, the propeller blade 76 is located inside the discharge pipe 5. The rotational motion of the propeller blade 76 can transport the granular potassium fertilizer accumulated at the bottom of the inner cavity 10 outward to achieve discharge, avoiding the accumulation of granular potassium fertilizer in the discharge pipe 5 and blocking it, thus improving the smoothness of material discharge in this device. The rotational motion of the propeller blade 76 inside the discharge pipe 5 can discharge the material from the discharge pipe 5, reducing the residue of material in the discharge pipe 5. The powder device of this application first crushes the larger lumps of potassium fertilizer, and then, with efficient stirring, fully disperses the lumps of potassium fertilizer into granules, effectively improving the uniformity and dissolution rate of potassium fertilizer during subsequent application, ensuring that potassium can be absorbed by crops more quickly and evenly, and improving the effect of potassium fertilizer use.

[0053] See also Figures 1 to 5 As shown, in one embodiment of this utility model, the powder device further includes an upper cover 3, a rotating shaft 15, and a third rotating rod 75. The top outer wall of the powder cylinder 2 is fixedly connected to the top inner wall of the feeding cylinder 1. The top of the powder cylinder 2 extends through the inner cavity 10 of the feeding cylinder 1. The upper cover 3 is placed on the top of the feeding cylinder 1 and threadedly connected to the top of the feeding cylinder 1 to prevent external dust from falling into the inner cavity of the feeding cylinder and contaminating the material inside. The feed inlet 4 is provided on the upper cover 3. Multiple support legs 8 are provided at the bottom of the feeding cylinder 1, and the multiple support legs 8 are spaced apart along the circumference of the feeding cylinder 1. One end of the third rotating rod 75 is fixedly connected to the second end of the second rotating rod 71, and the propeller blade 76 is provided on the outer periphery of the third rotating rod 75. The length extension direction of the rotating shaft 15 is the same as the length direction of the rolling roller 67. The rotating shaft 15 passes through the rolling roller 67.
