Description

Technical Field

[0001] This utility model relates to the technical field of hammer mills, and in particular to a hammer mill. Background Technology

[0002] A hammer mill is a mechanical device that uses high-speed rotating hammers to impact, shear, and grind materials, thereby crushing them into smaller particles. It is widely used in agriculture, feed processing, chemical industry, mining and other fields, and can efficiently crush materials such as grains, straw, and ores into particle sizes that meet the requirements of the process to meet the needs of subsequent processing or use.

[0003] The existing hammer mill crushers crush only through the impact of hammers and friction with screens in the crushing chamber, resulting in low crushing efficiency and thus affecting work efficiency.

[0004] An existing patent (publication number: CN218689983U) discloses a hammer mill, belonging to the field of crushing technology. It includes a crushing chamber containing several crushing toothed plates, each with teeth. The crushing toothed plates are evenly distributed in a ring around the crushing chamber, with the teeth located at the ends of the plates pointing towards the axis of the crushing chamber. The crushing chamber can be an integral or separate structure. This invention features crushing toothed plates within the crushing chamber. After being struck by high-speed rotating hammers and colliding with the crushing toothed plates, the material is struck again by the hammers. Through multiple impacts, the material can be rapidly crushed, thereby improving crushing efficiency.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, the existing hammer mills mostly have a single-chamber structure for their crushing chambers, which is not conducive to the graded crushing of materials, resulting in low crushing efficiency. In addition, most crushers are inconvenient to disassemble and install during maintenance, affecting the subsequent maintenance efficiency of the crusher.

[0006] Therefore, a hammer mill is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a hammer mill that can solve the problems of existing hammer mills, which mostly have a single-cavity crushing chamber structure, making it inconvenient to classify and crush materials, resulting in low crushing efficiency. At the same time, most crushers are inconvenient to disassemble and install during maintenance, affecting the maintenance efficiency of the subsequent crusher.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a hammer mill, comprising a mill structure, a lower partition plate being snapped into the inner wall of the mill structure, a fixing mechanism being bolted to the left side of the lower partition plate, an upper partition plate being provided at the top of the lower partition plate, a cover being provided at the top of the mill structure, a sieve plate being provided on the inner wall of the mill structure, and a discharge hopper being provided at the bottom of the mill structure;

[0009] The fixing mechanism includes a knob, a first fixing block, and a second fixing block. The first fixing block is bolted to the upper partition on the side near the upper partition, and the second fixing block is bolted to the lower partition on the side near the lower partition. The surface of the knob is movably connected to the inner wall of the first fixing block, and the surface of the knob is threaded to the inner wall of the second fixing block.

[0010] Preferably, the bottom of the first fixing block is in close contact with the top of the second fixing block, and the inner wall of the crusher structure is rotatably connected to a rotating shaft.

[0011] Preferably, the inner wall of the first fixing block is provided with a mounting hole for use with the knob, and the inner wall of the second fixing block is provided with a threaded hole for use with the knob.

[0012] Preferably, the inner wall of the lower partition is provided with a first rotating groove for use with the rotating shaft, and the inner wall of the upper partition is provided with a second rotating groove for use with the rotating shaft.

[0013] Preferably, a mounting plate is bolted to the top of the sieve plate, and bolts are movably connected to the inner wall of the mounting plate, with the surface of the bolts threadedly connected to the inner wall of the crusher structure.

[0014] Preferably, a mounting sleeve is bolted to the surface of the rotating shaft, and a rotating plate is bolted to the surface of the mounting sleeve.

[0015] Preferably, the inner wall of the rotating plate is movably connected to a rotating shaft, the surface of the rotating shaft is movably connected to a sleeve, and the surface of the rotating shaft is movably connected to a hammer assembly.

[0016] Preferably, the top of the cover is provided with a feed inlet, and the top of the feed inlet is provided with a sealing plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application, by setting a fixing mechanism, allows the lower partition to be snapped onto the inner wall of the crusher structure during use. Then, the upper partition is placed on top of the lower partition and fixed by the position of the first fixing block and the position of the second fixing block. This facilitates subsequent rotation of the upper and lower partitions by the knob on the inner wall of the first and second fixing blocks, thus restricting the position of the upper and lower partitions. This divides the inner wall of the crusher structure into three independent cavities, reducing cross-interference between materials in different areas and improving the crushing effect.

[0019] 2. This application, by setting up a cover and a discharge bin, and by using a structure in which a lower partition is snapped onto the inner wall of the crusher and an upper partition is placed on top of the lower partition, together with a screen plate and a discharge bin, clearly divides the crushing chamber into three independent areas, realizing graded crushing of materials in different chambers. Each chamber can independently process materials with different characteristics. At the same time, the screen plate independently screens to ensure precise particle size control, and the cover facilitates top maintenance. The overall structure effectively improves crushing efficiency and equipment maintenance convenience. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] A hammer mill includes a mill structure 1, a lower partition 3 is snapped into the inner wall of the mill structure 1, a fixing mechanism 2 is bolted to the left side of the lower partition 3, an upper partition 4 is provided on the top of the lower partition 3, a cover 5 is provided on the top of the mill structure 1, a screen plate 6 is provided on the inner wall of the mill structure 1, and a discharge hopper 7 is provided at the bottom of the mill structure 1.

[0030] The fixing mechanism 2 includes a knob 201, a first fixing block 202, and a second fixing block 203. The first fixing block 202 is bolted to the upper partition 4 on the side near the upper partition 4, and the second fixing block 203 is bolted to the lower partition 3 on the side near the lower partition 3. The surface of the knob 201 is movably connected to the inner wall of the first fixing block 202, and the surface of the knob 201 is threaded to the inner wall of the second fixing block 203.

[0031] In this embodiment: By setting a fixing mechanism 2, during use, the lower partition 3 is snapped onto the inner wall of the crusher structure 1, and then the upper partition 4 is placed on top of the lower partition 3. The first fixing block 202 is fixed to the position of the upper partition 4, and the second fixing block 203 is fixed to the position of the lower partition 3. This facilitates subsequent rotation of the knob 201 on the inner wall of the first fixing block 202 and the second fixing block 203, restricting the position of the upper partition 4 and the lower partition 3, thus dividing the inner wall of the crusher structure 1 into three independent cavities. This design reduces cross-interference between materials in different areas and improves the crushing effect. By setting up a cover 5 and a discharge bin 7, and with a lower partition 3 snapped onto the inner wall of the crusher and an upper partition 4 placed on top of the lower partition 3, along with a screen plate 6 and a discharge bin 7, the crushing chamber is clearly divided into three independent areas. This allows for graded crushing of materials in different chambers, each of which can independently process materials with different characteristics. At the same time, the screen plate 6 independently screens to ensure precise particle size control, and the cover 5 facilitates top maintenance. The overall structure effectively improves crushing efficiency and equipment maintenance convenience.

[0032] Specifically, such as Figure 2 As shown, the bottom of the first fixing block 202 is in close contact with the top of the second fixing block 203, and the inner wall of the crusher structure 1 is rotatably connected to the rotating shaft 8.

[0033] Specifically, such as Figure 3 As shown, the inner wall of the first fixing block 202 is provided with a mounting hole 9 for use with the knob 201, and the inner wall of the second fixing block 203 is provided with a threaded hole 10 for use with the knob 201.

[0034] Specifically, such as Figure 3 As shown, the inner wall of the lower partition 3 is provided with a first rotating groove 11 that cooperates with the rotating shaft 8, and the inner wall of the upper partition 4 is provided with a second rotating groove 12 that cooperates with the rotating shaft 8.

[0035] In this embodiment: the rotating shaft 8 is provided to facilitate subsequent rotation and material crushing. The mounting hole 9 on the inner wall of the first fixing block 202 allows the knob 201 to rotate through the mounting hole 9 on the inner wall of the first fixing block 202. The threaded hole 10 on the inner wall of the second fixing block 203 allows the knob 201 to rotate through the threaded hole 10 on the inner wall of the second fixing block 203, which facilitates the subsequent restriction of the position of the upper partition 4 and the lower partition 3 by the knob 201. The first rotating groove 11 on the inner wall of the lower partition 3 and the second rotating groove 12 on the inner wall of the upper partition 4 facilitate the rotation of the rotating shaft 8 on the inner walls of the lower partition 3 and the upper partition 4, which is convenient for the user.

[0036] Specifically, such as Figure 4 As shown, a mounting plate 13 is bolted to the top of the sieve plate 6, and a bolt 14 is movably connected to the inner wall of the mounting plate 13. The surface of the bolt 14 is threaded to the inner wall of the crusher structure 1.

[0037] Specifically, such as Figure 5 As shown, a mounting sleeve 15 is bolted to the surface of the rotating shaft 8, and a rotating plate 16 is bolted to the surface of the mounting sleeve 15.

[0038] In this embodiment: by setting the mounting plate 13 and bolts 14, the mounting plate 13 is fixed to the screen plate 6 during use, which facilitates the subsequent placement of the screen plate 6 on the inner wall of the crusher structure 1 by the mounting plate 13. Then, the mounting plate 13 and the inner wall of the crusher structure 1 are rotated by the bolts 14, which helps to restrict the position of the mounting plate 13 and facilitates the subsequent stable screening of materials by the screen plate 6. By setting the mounting sleeve 15 and rotating plate 16, the mounting sleeve 15 and rotating plate 16 are rotated by the rotating shaft 8, which facilitates the subsequent crushing of materials.

[0039] Specifically, such as Figure 5 As shown, a rotating shaft 17 is movably connected to the inner wall of the rotating plate 16, a sleeve 18 is movably connected to the surface of the rotating shaft 17, and a hammer assembly 19 is movably connected to the surface of the rotating shaft 17.

[0040] Specifically, such as Figure 6As shown, the top of the cover 5 is provided with a feed inlet 20, and the top of the feed inlet 20 is provided with a sealing plate 21.

[0041] In this embodiment: by setting a rotating shaft 17, a sleeve 18 and a hammer assembly 19, the rotating plate 16 is movably connected to the hammer assembly 19 through the rotating shaft 17 and the sleeve 18, so that the hammer assembly 19 can swing flexibly during the crushing process, enhancing the impact effect on the material and the uniformity of crushing. The feed port 20 and the sealing plate 21 at the top of the cover 5 are set to facilitate the precise input of materials into the crushing chamber. At the same time, the sealing plate 21 can prevent dust from leaking out during the crushing process, improving the safety and environmental protection of the crusher structure 1.

[0042] Working Principle: During the use of the crusher structure 1, a fixing mechanism 2 is set up. In use, the lower partition 3 is engaged with the inner wall of the crusher structure 1. Then, the upper partition 4 is placed on top of the lower partition 3. The first fixing block 202 is fixed to the upper partition 4, and the second fixing block 203 is fixed to the lower partition 3. This allows for subsequent rotation of the knob 201 along the inner walls of the first and second fixing blocks 202 and 203, restricting the positions of the upper partition 4 and lower partition 3, thus dividing the inner wall of the crusher structure 1 into three sections. Each chamber is independent, reducing cross-interference between materials in different areas and improving the crushing effect. By setting up a cover 5 and a discharge bin 7, and with a lower partition 3 snapped onto the inner wall of the crusher and an upper partition 4 placed on top of the lower partition 3, the crushing chamber is clearly divided into three independent areas in conjunction with the screen plate 6 and the discharge bin 7. This allows for graded crushing of materials in different chambers, and each chamber can independently process materials with different characteristics. At the same time, the screen plate 6 independently screens to ensure precise particle size control, and the cover 5 facilitates top maintenance. The overall structure effectively improves crushing efficiency and equipment maintenance convenience.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
