Description
Technical Field
[0001] This utility model relates to the field of road crushing technology, specifically a multi-hammer stone crusher with an anti-splash structure. Background Technology
[0002] The multi-hammer stone crusher is a special equipment for the crushing and stone-making of old cement concrete pavement, and it is widely used in highway maintenance, reconstruction and expansion projects.
[0003] Traditional multi-hammer crushers produce a large amount of crushed stone and dust during use. Construction workers add protective nets to prevent the crushed stone from flying everywhere.
[0004] However, in actual use, because the hammer is in free fall, the impact point may deviate from the preset position. This may result in some areas being over-fractured while others remain unfractured, leading to overlapping impact ranges or excessively large gaps. This situation disrupts the overall crushing rhythm, reduces work efficiency, and may ultimately cause significant elevation differences and irregular potholes on the road surface, requiring construction workers to rework. Rework not only significantly increases construction costs but also severely slows down the construction progress. Utility Model Content

Beneficial effects
[0011] This utility model provides a multi-hammer crusher with an anti-splash structure. It offers the following advantages: This multi-hammer crusher with an anti-splash structure, through the cooperation of a connecting plate, guide rail, pulley, and cleaning block, guides the movement of the hammers, ensuring that the impact point of the falling hammers does not deviate from the preset position.

[0018] 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.
[0019] In actual use, because the hammer is in free fall, the impact point may deviate from the preset position. This may result in some areas being over-fractured while others remain unfractured, leading to overlapping impact ranges or excessively large gaps. This will disrupt the overall crushing rhythm, reduce work efficiency, and ultimately cause significant elevation differences and irregular potholes on the road surface, requiring construction workers to rework. Rework will not only significantly increase construction costs but also severely slow down the construction progress.
[0020] In view of this, the present invention provides a multi-hammer crusher with an anti-splash structure. This multi-hammer crusher with an anti-splash structure guides the movement of the hammers through the cooperation of a connecting plate, guide rail, pulley, and cleaning block, ensuring that the impact point of the falling hammers does not deviate from the preset position. This avoids overlapping impact ranges or excessive gaps, ensuring that the road surface after construction can form a uniform and compliant crushing effect without deep depressions or bulges. This lays a solid foundation for subsequent paving or reconstruction, not only improving construction efficiency but also ensuring construction costs.
[0021] Those skilled in the art will connect the electrical components and their compatible power supplies in this case using wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle below, where the electrical components are connected in the order of operation. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without further explanation of electrical control.
[0022] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.
[0023] Example 1, by Figure 1-4It is known that a multi-hammer crusher with an anti-splash structure includes a fixed plate 1, a protective plate 2 fixedly connected to the bottom of the fixed plate 1, a first hydraulic cylinder 3 fixedly connected to the top of the fixed plate 1, an electromagnetic base 4 provided below the fixed plate 1, the electromagnetic base 4 fixedly connected to the output end of the first hydraulic cylinder 3, a breaker hammer 5 fixedly connected to the bottom of the electromagnetic base 4, and a guide mechanism provided on the outer wall of the breaker hammer 5; the guide mechanism includes a connecting plate 6, a guide rail 7, a pulley 8, and a cleaning block 9; the connecting plate 6 is fixedly connected to the outer wall of the breaker hammer 5, the guide rail 7 is provided on the side of the outer wall of the connecting plate 6 away from the breaker hammer 5, the top of the guide rail 7 is fixedly connected to the bottom of the fixed plate 1, the pulley 8 is slidably connected to the inner wall of the guide rail 7, the pulley 8 is rotatably connected to the inner wall of the connecting plate 6 through a pin shaft, and cleaning blocks 9 are provided at both the top and bottom of the pulley 8, the two cleaning blocks 9 are fixedly connected to the top and bottom of the connecting plate 6 respectively, and the two cleaning blocks 9 are slidably connected to the inner wall of the guide rail 7;
[0024] In the specific implementation process, it is worth noting that the fixed plate 1 is a rectangular plate with multiple threaded holes on its top. Its material can be Q345 steel. The protective plate 2 is similar to a square tube, made of the same material as the fixed plate 1. The two are fixedly connected by bolts. A heat dissipation mesh is installed on the outer wall of the protective plate 2. The heat dissipation mesh is made of alloy material, and its specific mesh size is not limited, as long as it meets the operational requirements and ensures effective internal heat dissipation. Three first hydraulic cylinders 3 are provided, all fixedly connected to the top of the fixed plate 1 and arranged side-by-side. Their output ends extend into the interior of the protective plate 2. The model of the first hydraulic cylinders 3 can be HSG-K100 / 55-800. Three electromagnetic bases 4 are provided, each installed on one of the three first hydraulic cylinders. At the bottom of the pressure cylinder 3, the electromagnetic base 4 is model MQZ-15. This model uses DC power supply, has stable adsorption force, and can quickly load and unload the breaker hammer 5. Its outer shell is mostly made of cast steel, and the internal coil insulation level reaches F class, which can adapt to the vibration and dust environment of stone crushing operations. The specific model needs to be fine-tuned according to the actual weight of the breaker hammer 5. There are three breaker hammers 5, and their material can be high-chromium cast iron. Each breaker hammer 5 has a connecting plate 6 on each of its four sides, and its material can be 45 carbon steel. There are multiple guide rails 7, and each guide rail 7 has guide grooves on both sides of its outer wall, ensuring that each side wall of the connecting plate 6 faces a guide groove. There are multiple pulleys 8, and their material can be ductile iron. In addition to being used for... A pin connection or a ball bearing connection can be used to make the rotation more flexible and reduce energy consumption. A connecting plate 6 is equipped with two cleaning blocks 9. The cross-section of the cleaning blocks 9 is similar to a triangle, and their material can be polyurethane elastomer, which can efficiently remove gravel particles, dust, and other debris from the guide rail 7. In actual operation, firstly, the construction personnel use an external positioning device to move the multi-hammer crusher with an anti-splash structure directly above the construction area, aligning the breaker hammer 5 with the construction area. Then, the first hydraulic cylinder 3 is activated via an external controller. The first hydraulic cylinder 3 drives the electromagnetic base 4 to rise. The electromagnetic base 4 is always energized. The electromagnetic base 4 drives the breaker hammer 5 to rise. After the breaker hammer 5 reaches the designated position, the construction personnel disconnect the power. When the magnetic base 4 is powered off, the electromagnetic base 4 is de-energized, the attractive force on the top of the breaker hammer 5 disappears, and the breaker hammer 5 falls naturally under the influence of gravity to carry out construction in the construction area. When the breaker hammer 5 falls, it drives the four connecting plates 6 on its outer wall to move. The four connecting plates 6 drive the pulley 8 and the cleaning block 9 to move along the guide groove on the guide rail 7. At the same time, the cleaning block 9 cleans up foreign objects that splash into the guide groove, ensuring the normal movement of the pulley 8 and preventing the breaker hammer 5 from deviating, thereby ensuring the falling trajectory and crushing effect of the breaker hammer 5. The above-mentioned structures that require power are powered through external wires, or a vehicle power supply can be used. Through the cooperation of the above structures, the working stability of the multi-hammer stone crusher with anti-splash structure is improved.
[0025] Furthermore, a dust suppression mechanism is provided on the outer wall of the protective plate 2; the dust suppression mechanism includes a water tank 10, a dust cover 11, a flow channel 12, a nozzle 13, and a connecting pipe 14; the water tank 10 is fixedly connected to the outer wall of the protective plate 2, and a dust cover 11 is provided below the water tank 10. The dust cover 11 is fitted onto the outer wall of the protective plate 2. A flow channel 12 is provided on the top of the dust cover 11. The nozzle 13 is connected to the end of the flow channel 12. The connecting pipe 14 is connected to the top of the flow channel 12. The top of the connecting pipe 14 is connected to the bottom of the water tank 10.
[0026] In the specific implementation process, it is worth noting that the water tank 10 is roughly rectangular in shape and fixed to the front of the protective plate 2. A water inlet is located at its top, and a water pump is installed inside to provide initial kinetic energy to the water. Furthermore, a liquid level sensor can be added inside the water tank 10 to monitor the remaining water level in real time during operation, ensuring stable dust suppression. The dust cover 11 can be made of high-density polyethylene, and a rubber buffer pad is fixedly connected to its bottom. The dust cover 11 consists of an upper and lower section, which are fixed together with a high-strength adhesive. An annular flow groove 12 is machined between the two sections. The flow groove 12 consists of an annular groove and a tubular groove parallel to the outer wall of the dust cover 11, and the two sections are connected. Multiple circular holes are opened on the inner wall of the dust cover 11, and these holes are connected to the annular groove. The number of circular through holes can be set according to actual needs. The nozzle 13 is an atomizing nozzle, and its number is the same as the number of circular through holes. The connecting pipe 14 can be a corrugated pipe so that it can move up and down with the dust cover 11. When it is necessary to reduce dust inside the dust cover 11, the construction personnel start the water pump through the external controller. The water pump drives the water in the water tank 10 to flow into the inside of the connecting pipe 14. The water flows from the inside of the connecting pipe 14 to the inside of the flow channel 12, and then enters multiple nozzles 13 through the flow channel 12. Finally, it is sprayed into the construction area inside the dust cover 11 through the nozzles 13 to reduce dust. This not only improves the working environment of the construction personnel and reduces the risk of occupational diseases, but also protects the surrounding ecology and avoids dust pollution. The above-mentioned structures that need to be powered are powered through external wires, or vehicle power can be used.
[0027] Furthermore, a dustproof net 15 is fixedly connected to the outer wall of the nozzle 13;
[0028] In the specific implementation process, it is worth noting that the dustproof net 15 is fixed to the outer wall of the nozzle 13 by bolts. Its material can be stainless steel. The dustproof net 15 can not only prevent large foreign objects from damaging the nozzle 13, but also prevent foreign objects from clogging the water outlet of the nozzle 13, ensuring the normal operation of the dust suppression mechanism and improving the service life of the nozzle 13.
[0029] Example 2, by Figure 1-4It can be seen that the inner wall of the dust cover 11 is fixedly connected to the slider 16, and the outer wall of the slider 16 away from the inner wall of the dust cover 11 is slidably connected to the slide rail 17, which is fixedly connected to the outer wall of the protective plate 2.
[0030] In the specific implementation process, it is worth noting that the slider 16 is an electric slider, and its model can be PA66-GF30, with a self-locking function to ensure the accuracy of the slider 16 movement. The slide rail 17 can be made of high-density polyethylene. In actual work, the height of the dust cover 11 can be adjusted by the slider 16 and the slide rail 17 to adapt to different terrains and ensure the working effect of the dust cover 11. The above-mentioned structures that require power are powered through external wires, or a vehicle power supply can be used.
[0031] Furthermore, a support plate 18 is fixedly connected to the side wall of the fixed plate 1, a second hydraulic cylinder 19 is fixedly connected to the bottom of the support plate 18, a connecting seat 20 is fixedly connected to the bottom of the second hydraulic cylinder 19, a limit plate 21 is provided on the side of the outer wall of the second hydraulic cylinder 19 away from the protective plate 2, the bottom of the limit plate 21 is fixedly connected to the top of the connecting seat 20, and the inner wall of the limit plate 21 is slidably engaged with the outer wall of the support plate 18.
[0032] In the specific implementation process, it is worth noting that the support plate 18 is generally square in shape and is made of the same material as the fixed plate 1. A 'T'-shaped metal rod is bolted to the side of its outer wall away from the fixed plate 1. The model of the second hydraulic cylinder 19 can be selected according to actual needs, as long as it meets the operational requirements; for example, it can be the HSK-80 / 45-500 model. The connecting seat 20 is made of the same material as the support plate 18, and its cross-section is similar to a 'C' shape. A circular through hole is machined on its top for easy installation with other devices. The limiting plate 21 is made of the same material as the fixed plate 1, and its side wall has a rectangular through groove that mates with the 'T'-shaped metal rod. The support plate 18 can be limited. In actual operation, the entire multi-hammer crusher with anti-splash structure is a certain distance from the ground, which makes it convenient for construction personnel to move the multi-hammer crusher. When it reaches the designated position, the construction personnel start the second hydraulic cylinder 19 through the external controller. The output end of the second hydraulic cylinder 19 descends, thereby driving the support plate 18 to descend. The support plate 18 drives the entire multi-hammer crusher with anti-splash structure to descend, bringing it closer to the construction area. This improves the mobility of the multi-hammer crusher with anti-splash structure. The above-mentioned structure that needs to be powered is powered through an external wire, or a vehicle power supply can be used.
[0033] 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.
