Description

Technical Field

[0001] This utility model belongs to the field of crushing chambers, specifically relating to an integrated crushing chamber structure and a crusher. Background Technology

[0002] In existing technologies, the material crushing process does indeed face many challenges. These problems not only affect production efficiency but also directly restrict the improvement of product quality. Specifically:

[0003] 1. Low efficiency: Traditional crushing equipment typically relies on a single power source to drive the moving blades for cutting operations, lacking effective auxiliary mechanisms to enhance the crushing effect. For example, when processing materials with high hardness or strong fibrous properties, relying solely on the rotational cutting of the moving blades is insufficient to achieve rapid and thorough crushing. Furthermore, due to design limitations, these devices often fail to make good use of space and energy, resulting in a limited material processing capacity per unit time.

[0004] 2. Uneven Grinding: Uneven grinding quality mainly stems from the inability to maintain a constant optimal gap between the moving and stationary blades. This issue allows some material to be discharged through the outlet without being fully cut, resulting in uneven particle size distribution. For applications requiring specific particle sizes (such as pharmaceuticals and food processing), this unevenness can lead to problems in subsequent process steps, and in the absence of effective adjustment mechanisms, it can affect the performance and consistency of the final product. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose an integrated crushing chamber structure and crusher with simple overall structure, good processability, high flexibility, and improved crushing performance.

[0006] The technical solution adopted by this utility model to solve its technical problem is to propose an integrated crushing chamber structure, including: a shell, which has an internal cavity for installing moving blades, and the shell has a first through groove and a second through groove along its axial direction. The first through groove and the second through groove are both connected to the cavity, and the first through groove and the second through groove are respectively used to connect the feed pipe and the discharge pipe, so that the material entering through the feed pipe can be crushed by the moving blades and discharged from the discharge pipe.

[0007] The fixed blade is mounted on the housing and extends movably into the receiving cavity to assist the moving blade in crushing the material. The adjusting component is mounted on the housing and connected to the fixed blade to adjust the gap between the fixed blade and the moving blade to prevent material from being missed and falling into the discharge pipe.

[0008] In the above-mentioned integrated crushing chamber structure, the shell is provided with a waist-shaped hole, the length direction of the waist-shaped hole is parallel to the radial direction of the shell, and the adjusting member moves through the waist-shaped hole and is connected to the fixed blade.

[0009] In the above-mentioned integrated crushing chamber structure, a guide groove is provided on the shell, the guide groove is connected to the receiving cavity and the waist-shaped hole respectively, and the fixed blade is movably disposed in the guide groove.

[0010] In the aforementioned integrated crushing chamber structure, both sides of the guide groove in the width direction are formed with a first clearance portion and a second clearance portion arranged at an angle.

[0011] In the aforementioned integrated crushing chamber structure, the guide groove is provided with clearance grooves at opposite corners, and the fixed blade extends diagonally into the clearance grooves.

[0012] In the above-mentioned integrated crushing chamber structure, a fixed blade mounting plate is also provided on the shell. The fixed blade mounting plate is close to the opening end of the guide groove away from the receiving cavity, and a cover plate is detachably connected to the fixed blade mounting plate.

[0013] In the above-mentioned integrated crushing chamber structure, the shell has an extension in its radial direction, and the extension has a plurality of mounting holes distributed in an annular pattern at equal intervals. The mounting holes allow fasteners to pass through to restrict the movement of the shell.

[0014] In the aforementioned integrated crushing chamber structure, a mounting hole is also formed on the shell, and a bearing is installed in the mounting hole. The rotating shaft of the moving blade is interference-fitted with the inner ring of the bearing.

[0015] In the aforementioned integrated crushing chamber structure, a stepped hole is also formed inside the receiving chamber, which is used to install a coupling sleeve.

[0016] The technical solution adopted by this utility model to solve its technical problem is to also propose a pulverizer, including one of the above-mentioned integrated pulverizing chamber structures.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) The present invention provides an integrated crushing chamber structure and crusher. By adopting the integrated processing method of frame manufacturing, the process flow is optimized, so that the material can be crushed quickly and efficiently under the combined action of the passive blade and the fixed blade after entering the crushing chamber, thereby improving the overall crushing efficiency. At the same time, the existence of the adjustment component allows users to accurately adjust the gap between the fixed blade and the moving blade according to actual needs. This not only avoids the problem of material falling into the discharge pipe before being fully crushed, but also ensures the fineness and uniformity of the crushed material, greatly improving the quality of the final product.

[0019] (2) The design of the guide groove, combined with the waist-shaped hole, allows the fixed blade to move precisely within a certain range, so that the gap between the moving blade and the fixed blade can be finely adjusted according to the different material characteristics, which simplifies the installation and adjustment process of the fixed blade, reduces the complexity of operation, and at the same time ensures that the material is thoroughly crushed, improving the crushing accuracy and uniformity.

[0020] (3) The fixed blade mounting plate provides a stable support point for the fixed blade, which effectively prevents the fixed blade from falling out of the guide groove. In addition, the cover plate further limits the fixed blade mounting plate, which effectively ensures the crushing efficiency and quality achieved by the fixed blade and the moving blade.

Detailed Implementation

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0027] like Figure 1 As shown, this solution mainly describes a one-piece crushing chamber structure used in a crusher. However, this one-piece crushing chamber structure is not limited to crushers and can also be applied to other places, such as blenders in daily life.

[0028] like Figures 1 to 3 As shown, an integrated crushing chamber structure includes: a shell 1, which has an internal cavity 10 for mounting a moving blade; the shell 1 has a first through groove 11 and a second through groove 12 along its axial direction, both of which are connected to the cavity 10; the first through groove 11 and the second through groove 12 are used to connect the feed pipe and the discharge pipe respectively, so that the material entering through the feed pipe can be crushed by the moving blade and discharged through the discharge pipe; a fixed blade 2 and an adjusting member; the fixed blade 2 is mounted on the shell 1 and extends movably into the cavity 10 to assist the moving blade in crushing the material; the adjusting member is mounted on the shell 1 and connected to the fixed blade 2 to adjust the gap between the fixed blade 2 and the moving blade to prevent material from being missed and falling into the discharge pipe.

[0029] In this embodiment, the required pulverizing effect, processing precision, and overall rigidity of the pulverizing chamber are very high. To achieve this, an integral pulverizing chamber machined in one piece was designed. Specifically, as shown in... Figures 1 to 3 As shown, in this embodiment, the shell 1 and all its structures are integrally molded, simplifying the process and ensuring the stability of the crushing performance. During the crushing operation, the material enters the first through-slot 11 of the shell 1 through the feed pipe. Since the first through-slot 11 is connected to the receiving cavity 10, the material can smoothly enter the receiving cavity 10 (i.e., the material is in...). Figure 2 The material is crushed from top to bottom. At this time, the moving blade located in the receiving cavity 10 starts to rotate and crushes the incoming material. Preferably, the moving blade is usually driven by a motor and applies shearing force to the material by rotating at high speed. In addition, before the crushing operation begins, the worker can install the fixed blade 2 on the housing 1 and extend it into the receiving cavity 10 to cooperate with the moving blade. It should be noted that the position of the fixed blade 2 can be adjusted as needed in this embodiment. That is, the operator can precisely adjust the gap between the fixed blade 2 and the moving blade through the adjusting component to prevent the material from falling into the discharge pipe without being fully crushed. This adjustment mechanism ensures the consistency and uniformity of the crushing effect. It is precisely because of the coordinated work of the moving blade and the fixed blade 2 that the material can be efficiently and thoroughly crushed in a short time, effectively avoiding the occurrence of missed cutting. Compared with the traditional single-blade design, the dual-blade system significantly improves the crushing efficiency.

[0030] The housing 1 has an oblong hole 13, the length of which is parallel to the radial direction of the housing 1. The adjusting member moves through the oblong hole 13 and is connected to the fixed knife 2.

[0031] Furthermore, such as Figure 2 and Figure 3 As shown, this embodiment utilizes the design of the oblong hole 13 to allow the adjusting component to move freely within a certain range (i.e., the fixed blade 2 moves closer to or further away from the receiving cavity 10). This means that the operator can flexibly adjust the gap between the fixed blade 2 and the moving blade according to different material characteristics and crushing requirements, ensuring that all materials can be fully crushed, thus improving the crushing quality and uniformity. In addition, this adjustment method simplifies the installation and adjustment process of the fixed blade 2 and reduces operational complexity. It should be noted that the adjusting component in this embodiment can be replaced by screws, bolts, or other connecting parts. By passing the adjusting component through the oblong hole 13 and connecting it to the fixed blade 2, while realizing the movement and adjustment of the fixed blade 2 relative to the housing 1, it can also lock the fixed blade 2 when the adjusting component is pressed against the outer wall of the housing 1, ensuring the stability of the fixed blade 2 when assisting the moving blade in crushing operations and avoiding the impact of mechanical vibration or other external factors on the crushing quality.

[0032] The housing 1 has a guide groove 14, which is connected to the receiving cavity 10 and the waist-shaped hole 13 respectively. The fixed knife 2 is movably disposed in the guide groove 14.

[0033] Furthermore, such as Figure 2 and Figure 3 As shown, when the operator adjusts the position of the fixed blade 2 using the adjusting device, the length direction of the oblong hole 13 is parallel to the radial direction of the housing 1. This ensures that the fixed blade 2 can be finely adjusted under the guidance of the guide groove 14 to achieve the optimal working gap. At the same time, the guide groove 14 also ensures that the fixed blade 2 can be stably held in the required position, thereby ensuring the efficiency and uniformity of the crushing process.

[0034] The two side walls of the guide groove 14 in the width direction are each formed with a first clearance portion 140 and a second clearance portion 141 arranged at an angle.

[0035] More preferably, such as Figure 2 and Figure 3 As shown, in this embodiment, the first clearance portion 140 and the second clearance portion 141 are preferably arc-shaped surfaces or two inclined surfaces arranged at an angle. This design allows the adjusting member to perform fine-tuning operations more smoothly when it passes through the waist-shaped hole 13 and is connected to the fixed blade 2. That is, these clearance portions provide additional space for the adjusting member, reducing friction and wear between components (i.e., friction and resistance between the fixed blade 2 and the guide groove 14 when it moves), extending the service life of the fixed blade 2, and ensuring the accuracy and stability of the adjustment.

[0036] More preferably, such as Figure 2 and Figure 3As shown, in this embodiment, clearance grooves 143 are also provided at opposite corners of the guide groove 14, and the fixed blade 2 extends diagonally into the clearance grooves 143. This clearance groove 143 design provides additional operating space for the fixed blade 2, allowing it to move and position more flexibly within the guide groove 14. This not only improves the flexibility of adjustment but also effectively prevents the fixed blade 2 from getting stuck when adjusting its position within the guide groove 14, ensuring the accuracy of the gap adjustment between the fixed blade 2 and the moving blade, and improving the crushing quality.

[0037] The housing 1 is also provided with a fixed blade mounting plate 15, which is attached to the opening end of the guide groove 14 away from the receiving cavity 10, and a cover plate 16 is detachably connected to the fixed blade mounting plate 15.

[0038] More preferably, such as Figure 2 and Figure 3 As shown, with the fixed blade 2 extending into the guide groove 14, the operator can then cover the opening end of the guide groove 14 with the fixed blade mounting plate 15. It should be noted that the fixed blade mounting plate 15 can be detachably connected to the housing 1 using screws, bolts, or other connecting parts, thus providing a stable foundation support point for the fixed blade 2 and ensuring the stability and positioning accuracy of the fixed blade 2 after it mates with the adjusting parts. With the cover plate 16 fixed using the same installation method, the fixed blade fixing plate 15 is prevented from shaking due to mechanical vibration or other external factors, effectively improving the stability of the fixed blade 2 fixing plate. This ensures the safety of the operator during the crushing process. The overall structure is simple, making daily cleaning and periodic maintenance easier and faster, thus improving work efficiency.

[0039] The housing 1 has an extension 17 formed in its radial direction. The extension 17 has a plurality of mounting holes 170 that are equidistantly distributed in an annular pattern. The mounting holes 170 allow fasteners to pass through to restrict the movement of the housing 1.

[0040] More preferably, such as Figure 2 and Figure 3 As shown, for the installation of the housing 1 in this embodiment, the extension 17 can be pre-pressed against the position to be installed. After the multiple mounting holes 170 are aligned with the installation position, fasteners (such as bolts, screws, etc.) can be passed through these mounting holes 170 to firmly fix the housing 1 in the required position. This effectively prevents the housing 1 from being displaced or shifted due to vibration or other reasons during operation, thereby enhancing the overall stability and safety of the equipment. The entire operation process is simple and convenient, which helps with the subsequent maintenance or replacement of the crushing chamber.

[0041] More preferably, such as Figure 2As shown, this embodiment also has a mounting hole 18 formed on the housing 1. During the installation of the moving blade, the rotating shaft of the moving blade can be interference-fitted with the inner ring of the bearing in the mounting hole 18. The high-quality bearing can effectively reduce the friction between the rotating shaft and the housing 1, reduce the wear and noise generated during equipment operation, extend the service life of the equipment, and at the same time ensure the stability and accuracy of the rotating shaft when rotating at high speed, reduce unnecessary shaking or deviation, and improve crushing efficiency and quality.

[0042] More preferably, such as Figure 2 As shown, similarly, this embodiment also forms a stepped hole 100 in the receiving cavity 10. The design of the stepped hole 100 can not only realize the installation of the coupling sleeve, but also provide precise positioning and support for the coupling sleeve, ensuring efficient connection between the power source and the moving tool shaft. While reducing installation time and complexity, it also ensures the operating efficiency of the entire system.
