Description

Technical Field

[0001] This utility model relates to the field of agarwood processing technology, and more specifically, to an agarwood crushing and sieving tool. Background Technology

[0002] Agarwood, a precious spice and traditional Chinese medicine, undergoes a processing flow that includes core steps such as crushing and sieving. The aim is to prepare a refined product with uniform particle size to meet the needs of subsequent extraction, blending, or direct application. The crushing process employs a low-temperature physical crushing technique, avoiding oil volatilization and degradation of active ingredients through non-thermal processing. This breaks down the lumpy raw material into coarse particles, maximizing the retention of core active substances. The sieving process utilizes a multi-stage vibrating sieve device for grading, removing excessively coarse particles and returning them to the crushing process for reprocessing, ensuring the uniformity of the intermediate product's particle size.

[0003] However, in the aforementioned processing flow, when the crushed agarwood granules are processed by the screening device, some substandard granules with excessive particle size easily become trapped in the screening mesh, causing blockage of the screening channel. This phenomenon not only hinders the normal feeding and flow of qualified granules but also requires frequent machine shutdowns for manual cleaning, severely disrupting the continuity of the processing flow and leading to a decrease in overall production efficiency. Furthermore, the existing equipment lacks an integrated function for real-time recovery and secondary crushing of substandard granules, making it easy for trapped granules and screened substandard granules to accumulate. This further exacerbates the risk of screening blockage and increases the dispersion of product particle size distribution, making it difficult to obtain standardized granular raw materials with uniform particle size in subsequent processing.

[0004] Therefore, there is a need to provide a tooling for crushing and sieving agarwood to solve the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an agarwood pulverizing and sieving device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A pulverizing and sieving fixture for agarwood includes a fixed base, a motor fixedly mounted on the top of the fixed base, a pulverizing cylinder fixedly mounted on the top of the motor, a sieving assembly, a pulverizing blade, a grinding assembly, and a drive assembly inside the pulverizing cylinder, the sieving assembly including a movable seat rotatably mounted on the top of the pulverizing cylinder, multiple feeding grooves evenly opened on the inner wall of the movable seat, a sieving seat on the top of the pulverizing cylinder, multiple movable blocks slidably connected inside the sieving assembly, a reciprocating screw fixedly connected to the bottom of the movable block, multiple gears rotatably connected to the bottom of the movable seat, the reciprocating screw and gears forming a helical pair transmission, and a gear ring fixedly connected to the inner wall of the pulverizing cylinder, the gears meshing with each other.

[0008] Preferably, the screening seat includes a mounting base and a screening screen. The mounting base is fixedly connected to the inner wall of the crushing cylinder, and the top of the movable seat is rotatably connected to the mounting base and fits against the lower surface of the screening screen.

[0009] Preferably, the drive assembly includes a drive shaft rotatably mounted inside the crushing cylinder, the bottom of the drive shaft being fixedly connected to the motor output shaft, and a movable sleeve being rotatably connected inside the crushing cylinder.

[0010] Preferably, the grinding assembly includes a lower grinding seat fixedly connected to the outside of the movable sleeve, an upper grinding seat fixedly connected inside the crushing cylinder, a connecting cylinder fixedly connected to the top of the upper grinding seat, and the upper surface of the connecting cylinder fitting against the lower surface of the movable seat.

[0011] Preferably, a crushing blade is fixedly connected to the top of the drive shaft, and the bottom of the crushing blade is rotatably connected to the interior of the movable seat.

[0012] Preferably, the top of the movable sleeve is fixedly connected to the inside of the movable seat, and the top of the movable block is provided with an inclined surface that slopes toward the center line of the movable seat.

[0013] Preferably, a drive wheel is fixedly connected to the outer side of the drive shaft, and a driven wheel is meshed between the movable sleeve and the drive wheel.

[0014] Preferably, the inside of the crushing cylinder is fixedly connected to an installation shaft, and the driven wheel is rotatably connected to the top of the installation shaft.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. Agarwood is fed into the crushing cylinder from the top. After being crushed by the crushing blades, qualified crushed particles fall into the movable seat through the screening screen of the screening base. At this time, the drive component drives the movable seat to rotate, and its bottom gear rolls along the gear ring, which in turn drives the reciprocating screw to move up and down repeatedly. The reciprocating screw drives the movable block to move up and down synchronously, forming a piston action to push the material in the screening screen. This can not only avoid the mesh from clogging, but also efficiently extract qualified crushed particles through negative pressure. At the same time, the positive pressure pushes the unqualified particles at the bottom to the crushing blades for secondary crushing, thereby improving the crushing efficiency.

[0017] 2. After the qualified agarwood particles are reset by the movable block, they fall into the connecting cylinder through the movable seat feed chute along its inclined structure. Then, they are conveyed by the connecting cylinder to the grinding mechanism composed of the upper grinding seat and the lower grinding seat for fine grinding. This achieves deep processing of the agarwood particles, further ensuring the uniformity and fineness of the product particle size, and meeting the core requirements of subsequent application scenarios.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] As attached Figures 1 to 7 As shown, this utility model provides an embodiment:

[0028] A tooling for crushing and sieving agarwood includes a fixed base 1, a motor 2 fixedly mounted on the top of the fixed base 1, a crushing cylinder 3 fixedly mounted on the top of the motor 2, a screening component 4, a crushing blade 5, a grinding component 6 and a drive component 7 arranged inside the crushing cylinder 3, the screening component 4 includes a movable seat 41 rotatably mounted on the top of the crushing cylinder 3, multiple feeding grooves are evenly opened on the inner wall of the movable seat 41, a screening seat 8 is arranged on the top of the crushing cylinder 3, multiple movable blocks 42 are slidably connected inside the screening component 4, a reciprocating screw 43 is fixedly connected to the bottom of the movable block 42, multiple gears 44 are rotatably connected to the bottom of the movable seat 41, and a helical pair transmission is formed between the reciprocating screw 43 and the gears 44, and a gear ring 45 is fixedly connected to the inner wall of the crushing cylinder 3, and the gears 44 and the gear ring 45 mesh with each other;

[0029] The screening seat 8 includes a mounting seat and a screening screen. The mounting seat is fixedly connected to the inner wall of the crushing cylinder 3, and the top of the movable seat 41 is rotatably connected to the mounting seat and fits against the lower surface of the screening screen.

[0030] The top of the drive assembly 7 is provided with a crushing blade 5, and the bottom of the crushing blade 5 is rotatably connected to the inside of the movable seat 41.

[0031] In practical application, the fixed base 1 is used as the basic support component, and the motor 2 mounted on its top provides the core power output for the whole set of equipment. After the motor 2 starts, the power is transmitted through the crushing cylinder 3 fixedly connected to the top, driving the core working components such as the crushing blade 5 and the screening component 4 inside the crushing cylinder 3 to operate synchronously, thus starting the integrated operation of agarwood crushing and screening.

[0032] After the agarwood raw material is put into the crushing cylinder 3, it is initially physically crushed under the action of the high-speed rotating crushing blade 5, forming granular materials of different sizes. The crushed materials fall under the action of gravity and enter the grading and screening process realized by the screening seat 8. The screening seat 8 is fixedly connected to the inner wall of the crushing cylinder 3 through the mounting seat. The screening screen mounted on it serves as the core grading element, and the materials are screened according to the preset particle size threshold. Qualified particles that meet the particle size requirements can penetrate the screening screen pores and enter the movable seat 41 of the screening component 4 below. Unqualified particles that exceed the particle size standard are retained on the upper surface of the screening screen for subsequent processing.

[0033] During the screening process, the gear 44 rotatably connected to the bottom of the movable seat 41 forms a meshing transmission structure with the gear ring 45 fixed to the inner wall of the crushing cylinder 3. When the movable seat 41 rotates, the gear 44 rotates under the constraint of the tooth surface of the gear ring 45. The helical transmission structure formed by the gear 44 and the reciprocating screw 43 converts the rotational motion of the gear 44 into the axial lifting motion of the reciprocating screw 43. Since the top of the reciprocating screw 43 is fixedly connected to the movable block 42 and the movable block 42 is in a sliding fit with the screening component 4, the axial movement of the reciprocating screw 43 directly drives the movable block 42 to slide up and down along the inner wall of the screening component 4.

[0034] The top of the movable seat 41 is in close contact with the lower surface of the screening screen of the screening seat 8. The movable block 42 slides up and down to form a dynamic screen cleaning mechanism: when sliding upward, it acts as a piston to push the unqualified particles embedded in the screen mesh, clearing the mesh blockage; when resetting downward, it provides a smooth channel for qualified particles to fall. At the same time, the feeding grooves evenly opened on the inner wall of the movable seat 41 serve as a conveying channel for qualified particles. After the movable block 42 completes the screen cleaning and reset, the qualified particles that have entered the movable seat 41 flow along the inclined surface of the movable block 42 and are finally directionally discharged through the feeding groove, completing the core process of crushing and screening.

[0035] The entire working process is achieved through the power output of motor 2, which realizes the linkage and coordination of crushing, screening and screen cleaning actions: the meshing transmission of gear 44 and gear ring 45 ensures the synchronicity of screen cleaning action, the spiral pair transmission ensures the stability of the lifting and lowering movement of movable block 42, and the structural cooperation between screening seat 8 and screening component 4 realizes the accurate classification of materials, effectively solving the problems of screening blockage and uneven particle classification in traditional equipment, and ensuring the continuity and efficiency of agarwood crushing and screening operation.

[0036] like Figure 3 and 4 As shown, the drive assembly 7 includes a drive shaft 71 rotatably mounted inside the crushing cylinder 3. The bottom of the drive shaft 71 is fixedly connected to the output shaft of the motor 2. A movable sleeve 72 is rotatably connected inside the crushing cylinder 3.

[0037] The top of the movable sleeve 72 is fixedly connected to the inside of the movable seat 41, and the top of the movable block 42 is provided with an inclined surface that slopes toward the center line of the movable seat 41.

[0038] The inside of the crushing cylinder 3 is fixedly connected to the mounting shaft 74, the top of the mounting shaft 74 is rotatably connected to the driven wheel 73, and the outside of the drive shaft 71 is fixedly connected to the driving wheel 75. The driven wheel 73 and the driving wheel 75 mesh with each other.

[0039] The bottom of the movable sleeve 72 is provided with a toothed groove that matches the driven wheel 73, and the driven wheel 73 and the toothed groove at the bottom of the movable sleeve 72 mesh with each other;

[0040] The crusher 5 is fixedly connected to the drive shaft 71.

[0041] In practical application, after the motor 2 starts, its output shaft directly transmits power to the drive shaft 71 fixedly connected at the bottom. The drive shaft 71 drives the crushing blade 5 on it to crush agarwood and drives the drive shaft 71 to rotate synchronously. The drive wheel 75 fixedly mounted on the outside of the drive shaft 71 rotates together with the drive shaft 71. Since the drive wheel 75 and the driven wheel 73 rotatably connected to the top of the mounting shaft 74 mesh with each other, a first-stage transmission mechanism is formed. The rotational motion of the drive wheel 75 is transmitted to the driven wheel 73 through the meshing relationship, realizing the direction and transmission of power.

[0042] Among them, the driven wheel 73 can reduce the speed between the driving wheel 75 and the movable sleeve 72, so that the crushing blade 5 rotates at high speed while the movable seat 41 and the grinding assembly 6 rotate at low speed.

[0043] The mounting shaft 74 fixedly connected inside the crushing cylinder 3 provides stable rotational support for the driven wheel 73, ensuring that the driven wheel 73 maintains a stable posture during meshing transmission. The side of the driven wheel 73 away from the driving wheel 75 meshes with the toothed groove at the bottom of the movable sleeve 72, forming a second-stage transmission structure. The rotational motion of the driven wheel 73 is further transmitted to the movable sleeve 72, driving the movable sleeve 72 to rotate around its own axis.

[0044] The top of the movable sleeve 72 is fixedly connected to the interior of the movable seat 41 of the screening component 4, so that the rotation of the movable sleeve 72 directly drives the movable seat 41 to rotate synchronously, laying the power foundation for the subsequent linkage gear 44, reciprocating screw 43 and movable block 42 of the movable seat 41. At the same time, the inclined surface structure on the top of the movable block 42, which is inclined towards the center line of the movable seat 41, provides a guiding effect for the qualified particles after screening during the rotation and reciprocating motion of the movable block 42 with the movable seat 41, ensuring that the material flows smoothly along the preset path, and achieving efficient material discharge in conjunction with the feeding trough on the inner wall of the movable seat 41.

[0045] The entire driving process achieves precise power transmission through two-stage meshing transmission. The fixed support of the mounting shaft 74 and the rotating assembly of the movable sleeve 72 ensure transmission stability, while the inclined structure of the movable block 42 optimizes material conveying efficiency. Together, they form a complete linkage system of driving, execution, and auxiliary conveying, providing reliable power guarantee and structural support for the crushing and screening operation of the entire tooling.

[0046] like Figure 3 and Figure 7 As shown, the grinding assembly 6 includes a lower grinding seat 62 fixedly connected to the outside of the movable sleeve 72, an upper grinding seat 61 fixedly connected inside the crushing cylinder 3, a connecting cylinder 63 fixedly connected to the top of the upper grinding seat 61, and the upper surface of the connecting cylinder 63 fitting against the lower surface of the movable seat 41.

[0047] In practical application, when the movable sleeve 72 rotates under the drive of the motor 2, the rotational motion of the movable sleeve 72 is directly transmitted to the lower grinding seat 62 because the lower grinding seat 62 is fixedly connected to the outside of the movable sleeve 72, causing the lower grinding seat 62 to rotate synchronously around its own axis. The upper grinding seat 61 is fixedly connected to the inside of the crushing cylinder 3, forming a relatively rotating grinding pair structure with the rotating lower grinding seat 62, providing the core working basis for material grinding.

[0048] The connecting cylinder 63 is fixedly connected to the upper grinding seat 61 at the top to form a material conveying transition channel, and its lower surface is in close contact with the lower surface of the movable seat 41 to ensure that the qualified particles discharged from the discharge chute of the movable seat 41 can completely enter the interior of the connecting cylinder 63, avoiding material leakage or retention. After the qualified agarwood particles after screening are discharged through the discharge chute of the movable seat 41, they smoothly enter the connecting cylinder 63 under the action of gravity, and are precisely guided by the connecting cylinder 63 to the grinding gap between the upper grinding seat 61 and the lower grinding seat 62.

[0049] As the lower grinding seat 62 continues to rotate, the shearing and squeezing forces formed between the upper grinding seat 61 and the lower grinding seat 62 finely grind the material. Through the relative motion between the fixed upper grinding seat 61 and the rotating lower grinding seat 62, the granular material is further refined, and finally agarwood products with more uniform particle size and finer texture are obtained, which meet the high precision requirements of subsequent extraction, blending or direct application, and ensure the stability of grinding efficiency and product quality.

[0050] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
