Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of compound fertilizer processing equipment, specifically a compound fertilizer material crusher. Background Technology
[0002] In the processing of compound fertilizers, material crushers are indispensable key equipment. During operation, the crushing components inside the crushing tank crush the materials under the action of a drive motor. However, existing crusher structures suffer from significant vibration during operation.
[0003] The high-speed rotation of the motor generates vibrations, which are transmitted through the inner and outer covers of the motor and then to the grinding tank. Due to resonance, the vibrations are amplified when they reach the outer cover of the motor and the grinding tank, resulting in loud noise, a harsh working environment, and potentially affecting the lifespan of the equipment and the health of the operators.
[0004] Existing vibration reduction solutions for crushers mostly use simple elastic elements or dampers, but their effects are limited and they cannot effectively reduce vibration.
[0005] Therefore, there is an urgent need for a new type of crusher structure that can effectively reduce vibration, lower noise, and improve work efficiency. Utility Model Content
[0006] The purpose of this invention is to overcome the aforementioned technical difficulties and provide a compound fertilizer material crusher that can effectively reduce vibration, lower noise, and improve work efficiency.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a compound fertilizer material crusher, comprising a support frame and a crushing device mounted on the support frame. The crushing device consists of a crushing tank, a crushing component, and a driving component. The crushing tank includes an outer tank and an inner tank, which are connected to form a vibration damping cavity. A vibration damping and noise reduction component is provided in the vibration damping cavity. The vibration damping and noise reduction component includes a first sound-absorbing plate layer, a resonant plate layer group, a vibration damping plate layer, and a second sound-absorbing plate layer. The first sound-absorbing plate layer is sleeved on the outer wall of the inner cylinder, and a resonant plate layer group is sleeved on the outer wall of the first sound-absorbing plate layer. The resonant plate layer group is connected to the second sound-absorbing plate layer through the vibration damping plate layer, and the second sound-absorbing plate layer is connected to the inner wall of the outer tank. A connecting cavity is provided between the resonant plate layer groups, and a first damping layer is embedded in the connecting cavity. The vibration damping plate layer is connected to the resonant plate layer group through a connecting block to form an energy-absorbing cavity, which is filled with a second damping layer. The vibration damping plate layer is connected to the second sound-absorbing plate layer through a spring group.
[0008] Furthermore, the resonant plate assembly includes a first resonant plate and a second resonant plate, the first damping layer is disposed between the first resonant plate and the second resonant plate, and springs connected to the first resonant plate and the second resonant plate are alternately disposed on the first damping layer.
[0009] Furthermore, the first damping layer includes inner damping and outer damping. The outer damping is annular in shape, and the inner damping is connected to the outer damping by multiple damping plates at equal intervals, so that they form multiple n-shaped damping cavities after connection.
[0010] Furthermore, the damping plate layer is formed by multiple equally spaced damping plates, making the damping plate layer have multiple annular n-shaped rings, with the openings facing the resonant plate layer group.
[0011] Furthermore, the second damping layer includes longitudinal damping that connects the damping plate layer and the resonant plate layer group at equal intervals and transverse damping that is staggered at equal intervals between the longitudinal damping layers.
[0012] Furthermore, the spring assembly includes a telescopic rod and a spring sleeved on the telescopic rod, and the spring assembly is staggered at equal intervals between the vibration damping plate layer and the second sound-absorbing plate layer.
[0013] The compound fertilizer material pulverizer provided by this utility model has the following beneficial effects:
[0014] This utility model connects the outer tank and the inner tank to form a vibration damping cavity. The vibration damping and noise reduction components installed in the vibration damping cavity effectively absorb the resonance generated during the operation of the crusher, thereby effectively reducing vibration, lowering noise, and improving work efficiency. This utility model is easy to operate and highly practical. It effectively solves the problem that existing crushers have large vibrations during operation, resulting in high noise levels, harsh working environment, and even affecting the service life of the equipment and the health of the operators.

Detailed Implementation
[0020] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. The described embodiments are merely some, not all, of these embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0021] like Figure 1-4 The present invention provides a compound fertilizer material crusher, including a support 1 and a crushing device mounted on the support 1. The crushing device consists of a crushing tank 2, a crushing component disposed within the crushing tank 2, and a driving component for driving the crushing component. The crushing tank 2 includes an outer tank 21 and an inner tank 22. The outer tank 21 and the inner tank 22 are connected to form a vibration damping cavity 3. That is, the lower end of the inner tank 22 is connected to the outer tank 21 through a support column, and the upper end of the outer tank 21 is connected to the inner tank 22 through a connecting block. In other words, the upper end of the outer tank 21 covers the upper end of the inner tank 22 through the connecting block, thereby forming a vibration damping cavity 3 between the outer tank 21 and the inner tank 22. The vibration damping cavity 3 is provided with vibration damping and noise reduction components, which include a first sound-absorbing plate layer 4, a resonant plate layer group 5, a vibration damping plate layer 6, and a second sound-absorbing plate layer 7. The first sound-absorbing plate layer 4, the resonant plate layer group 5, the vibration damping plate layer 6, and the second sound-absorbing plate layer 7 are arranged sequentially from the inside to the outside in the vibration damping cavity 3.
[0022] like Figure 2The first sound-absorbing plate layer 4 is sleeved on the outer wall of the inner cylinder, and a resonant plate layer group 5 is sleeved on the outer wall of the first sound-absorbing plate layer 4. The sound-absorbing plate layer is a sound-absorbing cotton board. Through the setting of the first sound-absorbing plate layer 4, the noise of the crushing component crushing material acting on the crushing tank 2 can be absorbed, and the propagation of noise can be hindered. A connecting cavity 8 is provided between the resonant plate layer groups 5, and a first damping layer 9 is embedded in the connecting cavity 8. The first damping layer 9 includes an inner damping 91 and an outer damping 92. The outer damping 92 is annular in shape, and the inner damping 91 is provided by multiple damping plates. The outer damping plate 92 is connected at equal intervals to form multiple n-shaped damping cavities, enabling it to form vibration-absorbing damping at multiple natural frequencies. This gives the resonant plate layer 5 sufficient bending stiffness and strength, further improving the vibration reduction effect. The resonant plate layer 5 includes a first resonant plate 51 and a second resonant plate 52. The first damping layer 9 is disposed between the first resonant plate 51 and the second resonant plate 52, and springs connected to the first resonant plate 51 and the second resonant plate 52 are staggered on the first damping layer 9 to reduce the transmission of vibration force in the damping cavity 3 and improve its practical performance.
[0023] The resonant plate layer 5 is connected to the second sound-absorbing plate layer 7 via the damping plate layer 6, and the second sound-absorbing plate layer 7 is connected to the inner wall of the outer tank 21. The second sound-absorbing plate layer 7 is a sound-absorbing foam board. By setting the second sound-absorbing plate layer 7, the noise of the crushing material acting on the crushing tank 2 by the crushing component can be absorbed, and the resonance between the driving component and the crushing tank 2 can be further reduced, thus hindering the propagation of noise. The damping plate layer 6 is connected to the resonant plate layer 5 via a connecting block to form an energy-absorbing cavity 10. The damping plate layer 6 is formed by multiple equally spaced damping plates, making the damping plate layer 6 have multiple annular n-shaped rings with the openings facing the resonant plate layer 5. The energy-absorbing cavity 10 is filled with a second damping layer 11. The second damping layer 11 includes longitudinal damping 111 that is equally spaced connecting the damping plate layer 6 and the resonant plate layer 5, and transverse damping 112 that is equally spaced and staggered between the longitudinal damping 111. The vibration damping plate layer 6 is connected to the second sound-absorbing plate layer 7 through the spring assembly 12. The spring assembly 12 includes a telescopic rod and a spring sleeved on the telescopic rod. The spring assembly 12 is staggered at equal intervals between the vibration damping plate layer 6 and the second sound-absorbing plate layer 7. The vibration force generated by the inner tank 22 of the spring assembly 12 is weakened, reducing the effect of the vibration force on the outer tank 21, thereby effectively reducing vibration, lowering noise, and improving the working environment.
[0024] The first damping layer 9 and the second damping layer 11 of this application are both made of high-molecular composite materials, which enable the vibration reduction and noise reduction components of this application to achieve good vibration absorption and noise reduction effects during the operation of the compound fertilizer material crusher, and also give the crusher of this application the advantages of a sturdy structure and long service life. Before use, this application checks whether the crusher is operating normally. Then, according to production needs, the compound fertilizer material is added to the crusher for crushing. After crushing according to production needs, the hydraulic control valve at the discharge end of the inner tank 22 is controlled by setting parameters through the operation controller to discharge the material. The outer tank 21 is also equipped with a maintenance window corresponding to the hydraulic control valve, which facilitates maintenance of the hydraulic control valve. Through production test comparison, it is found that when processing the same batch of material, the compound fertilizer material crusher provided by this application has a 12% higher overall vibration reduction and noise reduction effect compared to existing crushers without vibration reduction and noise reduction treatment. Compared to crushers using simple elastic elements or dampers, its overall vibration reduction and noise reduction effect is improved by 5%. This effectively solves the problem that existing crushers have large vibrations during operation, resulting in large noise, harsh working environment, and even affecting the service life of the equipment and the health of the operators.
