Description

Technical Field

[0001] This utility model relates to the technical field of crushing and sand making equipment, specifically, to a rotary crushing, sand making and shaping integrated machine. Background Technology

[0002] Crushers are widely used in many fields such as mining, metallurgy, building materials, highways, railways, water conservancy, and chemicals. With the standardization of the building materials aggregate market at present, the aggregates produced by conventional crushing equipment can no longer meet the requirements of the current aggregate market. Moreover, the crushing effect of the original crushing equipment is relatively simple. A single machine can only perform a single function of crushing, sand making, or shaping. If market needs are to be met, multiple machines need to be arranged into a production line, which poses a huge challenge to the overall planning of land use, environment, and procurement costs.

[0003] Therefore, it is necessary to design a device that integrates crushing, sand making, and shaping functions to meet the current market demand for this type of product. Utility Model Content

[0012] Preferably, the cylinder liner is made of vulcanized rubber, wear-resistant steel plate, cast steel plate, or high-manganese steel plate.

[0013] Preferably, the surface of the wear-resistant shaft is covered with a wear-resistant layer, which is a wear-resistant welding rod or a wear-resistant bushing.

[0014] Preferably, a sliding ring is provided on the outer circumferential surface of the outer rotating cylinder. The sliding ring is made of tin bronze. A corresponding annular slide is provided on the main frame. The annular slide is equipped with an adjustable clearance plate and a lubrication oil passage connecting the annular slide.

[0018] Preferably, the rotational speed and direction of the outer rotating cylinder and the inner rotating winch assembly are the same or different.

[0019] This utility model has substantial features and progress compared to the prior art. Specifically, this utility model has the following advantages:

[0020] 1. Due to its design as a dual-rotation mechanism with an internal vortex and an external rotation, the internal vortex requires less power, and a relatively low-power motor can be selected. It only needs to provide the material with the speed to be thrown. The material can be crushed and made into sand by impacting the liner and colliding with each other, which saves costs accordingly. The motor can be equipped with a frequency converter, and different input speeds can be selected for metal ores and non-metal ores to achieve a wider processing range. It can also refine the range of crushed products to a certain extent.

[0021] 2. The upper feeding frame structure with circumferentially distributed feeding holes can realize feeding in any direction around the circumference, which can effectively solve the feeding problem in case of insufficient space.

[0022] 3. The main shaft of the internal rotating blade shaft is made of high alloy steel, which is sturdy, wear-resistant, and can achieve a long service life; the number of spiral blades can be determined according to the production needs of crushing and sand making to meet the production requirements; the height adjustment of the material liner plate allows the material to form a liner between the material liner plate, spiral blades, and main shaft, avoiding excessive wear and improving the service life of the internal rotating blade shaft to meet the needs of long-term production; the wear-resistant material on the spiral blades can withstand long-term abrasion, and after the wear-resistant material is damaged, it can be re-applied to resume normal production, making it very convenient to use.

[0023] 4. All parts of the outer rotating cylinder are covered by liner plates, requiring only liner plate replacement to avoid greater losses. The sliding ring, made of tin bronze, is heat-fitted and fixed to a specific position on the cylinder. During operation, the sliding ring's mating surface slides together with the main frame's mating surface. The elastic deformation of the tin bronze absorbs a certain load, ensuring stable operation. The sliding cavity formed during operation is filled with lubricating oil, creating an oil bath lubrication. The lubrication system monitors the oil level and can supply oil at any time, ensuring the sliding area is always within the oil range, forming a solid oil film, reducing wear, and achieving better performance. The lower discharge pulley plate rotates with the outer rotating cylinder pulley via a V-belt, providing the required rotational speed to the outer rotating cylinder to meet production needs. The evenly distributed discharge ports on the lower discharge pulley plate allow for circumferential discharge, preventing material accumulation that could affect production.

[0024] 5. The main frame controls the position of the fixing point of the inner rotating impeller shaft bearing and the required clearance by adjusting the relative position of the lead screw and the positioning nut; it achieves the fit between the lead screw and the sliding ring of the outer rotating cylinder by adjusting the relative position of the lead screw and the positioning nut; and it controls the runout required during operation by determining the clearance adjustment plate; the lubrication system lubricates the slide rail through the circumferentially arranged lubrication oil channels on the flange plate to achieve stable and reliable production.

[0025] 6. Independent internal and external rotation, controllable and adjustable parameters, high flexibility; the desired product can be obtained by adjusting data parameters; by adjusting the rotation direction of the outer rotating cylinder while the internal rotating blade shaft rotates, multiple options such as crushing process, crushing and shaping process, crushing and sand making (coarse sand) process, crushing and sand making (fine sand) process, and crushing and sand making and shaping process can be obtained; at the same time, it can be interlocked with the upstream and downstream equipment to detect the operating status in advance, and stop the operation of the upstream and downstream equipment in time if any abnormality is found to avoid equipment damage; the hydraulic motor group structure can realize stepless speed regulation of production and can make overall and local process adjustments.

[0026] 7. The crushing chamber and the moving area of ​​the equipment are strictly separated, making it suitable for use in various harsh environments (mines or tunnels).

[0027] 8. The rotating lower discharge pulley plate enables rapid material discharge, avoiding excessive wear on the equipment's internal components, extending the lifespan of vulnerable parts, and reducing costs; the moving lower discharge pulley plate also prevents large pieces of material from accumulating at the discharge port and affecting the discharge process.

[0028] 9. The integral bolted connection structure of the external rotating cylinder allows for the removal of the cover plate in one direction to replace the wear-resistant shaft or liner, reducing replacement time and space and realizing the concept of rapid replacement and immediate production.

[0029] In summary, the rotary crushing, sand making and shaping integrated machine provided in this application integrates crushing, sand making and shaping functions into one, and has good working performance, meeting the current integrated processing needs of people. Attached Figure Description

[0037] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0038] like Figures 1-6 As shown, a rotary winch crushing, sand making and shaping integrated machine includes a main frame 1, an outer rotating cylinder 2, an inner winch assembly 3, an outer rotating power mechanism 4 and an inner winch power mechanism 5.

[0039] The outer rotating cylinder 2 is rotatably mounted on the main frame 1, and the outer rotating power mechanism 4 is mounted on the main frame 1 and is used to drive the outer rotating cylinder 2 to perform rotational motion.

[0040] Specifically, in this embodiment, the outer rotating cylinder 2 includes an upper plate 21, a cylinder liner 22, a wear-resistant shaft 23, a cylinder 24, a sliding ring 25, and a lower discharge pulley plate 26. The upper plate 21 is connected to the cylinder 24 by bolts. The cylinder liner 22 can be made of vulcanized rubber, wear-resistant steel plate, cast steel, or high manganese steel, depending on the material to be crushed. The cylinder liner 22 is bolted or vulcanized onto the cylinder according to the liner material, protecting the liner while impact crushing, impact sand making, or grinding and shaping the material. The wear-resistant shaft 23 is fixed between the upper plate 21 and the lower discharge pulley plate 26, and is evenly distributed in 6-20 groups around the circumference according to the crushing effect requirements. The number of groups around the circumference is adjusted when comparing the effects. The outer circumference of the wear-resistant shaft 23 is coated with a wear-resistant layer. Wear-resistant welding rods or wear-resistant bushings can be used to extend its service life. It rotates together with the cylinder 24. Depending on the stationary state, rapid forward rotation, slow forward rotation, rapid reverse rotation, and slow reverse rotation of the cylinder 24, it collides, strikes, and grinds the material, achieving the functions of crushing, sand making, and shaping. The tin bronze sliding ring 25 is thermally fitted to the cylinder 24, and they are fixed without slippage. During operation, the entire outer rotating cylinder assembly contacts the sliding surface of the main frame through the sliding surface of the sliding ring. The cylinder slides in a circular motion, with the number of sliding rings increasing according to the height of the cylinder to ensure smooth and abnormal operation. The lower discharge pulley plate 26 is bolted to the cylinder 24. A discharge port 27 is located on the outer circumference of the lower discharge pulley plate 26. Qualified materials after crushing are discharged through the discharge port 27 for further screening. A pulley groove 28 is provided on the outer circumference of the lower discharge pulley plate 26. The external rotating power mechanism 4, driven by a hydraulic motor, drives the external rotating cylinder pulley via a V-belt transmission, causing the cylinder to rotate statically, forwards, or in reverse. The lower discharge pulley plate is assembled with the lower part of the winch blade shaft via rolling bearings 1.

[0041] The inner swivel winch assembly 3 is installed inside the outer rotating cylinder 2, and the inner swivel winch power mechanism 5 is installed on the top of the main frame 1 and is used to drive the inner swivel winch assembly 3 to rotate in the outer rotating cylinder 2.

[0042] Specifically, in this embodiment, the internal vortex lifting power mechanism 5 includes a motor and a reducer. The reducer is connected to the main shaft via a coupling. The internal vortex lifting assembly 3 includes a main shaft 31, a spiral blade 32, and a material liner 33. The material liner 33 and the spiral blade 32 can be welded to the main shaft 31 in three or four equal parts according to the size of the material. The material liner is a vertical blade that is perpendicular to the spiral blade. The width of the material liner is the same as the width of the spiral blade. The material liner is located at the rear end of the spiral blade in the direction of rotation. The material can be arranged in layers on the main shaft according to its size, and the number of layers can be determined according to the hardness of the material. The liner 33 forms a material lining on the spiral blades 32, reducing the wear of the material on the main shaft 31 and the spiral blades 32. The upper spiral blades 32 evenly disperse the material entering the equipment, and the lower spiral blades 32 swirl the lower material, giving the material a certain kinetic energy to do work and crush it in the cavity. The material empowered by the spiral blades will have a high speed and will be crushed by impact with the material in the crushing chamber. The high-speed material will be crushed by impact with the cylinder liner 22 and shaped by impact with the wear-resistant shaft 23.

[0043] The main shaft is made of high alloy steel, the spiral blades are discontinuous spiral blades, and the surface of the spiral blades is provided with a wear-resistant layer.

[0044] The main frame 1 mainly consists of three flange plates 11, supports 12, adjusting screws 13, positioning nuts 14, annular slides 15, and clearance plates 16. The lower flange plate is bolted to the support 12. The appropriate distance between the flange plates is determined by adjusting the screws 13 and positioning nuts 14 for installing the outer rotating cylinder 2. The contact between the two sliding ring mating surfaces is adjusted by the positioning nuts 14, and real-time adjustments are made during production to avoid localized wear. A shaft hole is provided at the center of the upper flange plate. The upper and lower parts of the main shaft of the inner rotating winch assembly are respectively installed in the shaft holes of the upper flange plate and the lower discharge pulley plate via rolling bearings 17. Feed holes 18 and a feed rack 19 are provided around the shaft holes of the upper flange plate. The feed holes 18 and 19 are provided around the shaft holes. 13 and positioning nut 14 determine the adjustment of the installation position of the inner rotating winch assembly; adjust the clearance plate 16 to fully contact the two annular slides 15 of the sliding ring of the outer rotating cylinder, and adjust the gap between the upper mating surface of the sliding ring of the outer rotating cylinder and the clearance plate 16 with bolts to avoid the sliding oil film thickness of the two surfaces being too thick or too thin during operation; adjust the sealing ring between the clearance plate and the outer rotating cylinder to prevent lubricating oil leakage; lubricating oil channels 161 are evenly distributed on the circumference of the two flange plates in the thickness direction, which can inject an appropriate amount of lubricating oil into the mating surface space of the annular slides 15, thereby reducing friction and avoiding local overheating.

[0045] The feed rack 19 is connected to the bottom of the motor reducer, and the motor reducer is fixed in a suitable position to install the coupling; the lower part is bolted to the upper flange plate, providing fixed support for the motor reducer and providing a place for the feed hopper; the positions of the four feed holes 18 in the circumferential direction can be arranged according to the size of the site.

[0046] The external rotation power mechanism is a hydraulic motor, installed on the lower flange plate, and the tension of the transmission V-belt is adjusted by bolts; the external rotation power mechanism is connected to the external rotation cylinder pulley by a key; the external rotation power mechanism can achieve different states such as stationary, slow forward rotation, slow reverse rotation, fast forward rotation, and fast reverse rotation by switch control, adapting to different crushing environments.

[0047] Work process description:

[0048] During operation, the motor drives the reducer to rotate the inner vortex hoist assembly at an appropriate speed to reach the specified rotational speed. Material enters the outer rotating cylinder through the upper feed frame, first being accelerated by the inner vortex hoist blades. The material accelerated by the inner vortex hoist assembly impacts and crushes the outer rotating cylinder liner at extremely high speed. The material that impacts the outer rotating cylinder liner rebounds and collides again with material accelerated by the next stage blade shaft, performing work. After the collision, the material, having reduced speed, is then accelerated by the third stage blade shaft for further impact crushing. Material of acceptable particle size is discharged through the discharge port near the outer circumference of the lower discharge pulley plate. Unacceptable material is then accelerated upwards by the sixth stage blade shaft, impacting the outer rotating cylinder liner for further crushing. Acceptable material (small pieces) is discharged downwards, while unacceptable material (large pieces) is accelerated and crushed by the fifth stage blade shaft. The number of blade shaft levels in the inner vortex hoist assembly can be determined according to the required material. Generally, crushing requires four levels of blade shafts, while sand making and shaping require six levels. The verticality of the liner plate can be adjusted by 15 degrees to adjust the angle of material impact on the liner plate, and the height of the liner plate can be adjusted to control the thickness of the liner plate.

[0049] When the outer rotating cylinder is working, it slides and rotates relative to the main frame. The hydraulic motor unit of the outer rotating cylinder drives the pulley of the outer rotating cylinder through the transmission of the V-belt, thus driving the outer rotating cylinder to move. When the outer rotating cylinder is stationary, it can achieve the function of crushing and sand making (coarse sand): the material accelerated by the inner rotating winch blade shaft directly impacts the wear-resistant shaft and cylinder liner of the outer rotating cylinder. Excessively large materials are crushed by impacting the wear-resistant shaft first, and small materials impact the cylinder liner. To a certain extent, this balances the wear of vulnerable parts inside the outer rotating cylinder. When the wear difference between the upper and lower parts is large, the upper and lower direction of the wear-resistant shaft can be adjusted to continue working. The position of the cylinder liner can be adjusted (by adjusting the position of the cylinder liner). (Swapping the positions of the more worn liners with the less worn liners) allows for normal operation; when the outer rotating cylinder rotates in the same direction as the inner rotating winch blade shaft at a slow speed, it achieves the effect of crushing and shaping: because when the outer rotating cylinder rotates at low speed, the material accelerated by the inner rotating winch blade shaft impacts the cylinder liner and wear-resistant shaft, the impact force is reduced, and the wear-resistant shaft contacts the crushed material, resulting in a grinding effect, thus achieving the effect of crushing and shaping; when the outer rotating cylinder rotates in the same direction as the inner rotating winch blade shaft at high speed, it achieves the effect of crushing: because when the outer rotating cylinder rotates at high speed, the material accelerated by the inner rotating winch blade shaft only impacts the wear-resistant shaft, and the outer rotating cylinder... The wear-resistant shaft rotates while impacting the material. At this point, the material experiences relatively singular impacts and light force, only achieving a crushing effect. However, when the outer rotating cylinder rotates in rapid opposite directions to the inner rotating blade shaft, crushing and sand making (fine sand) are achieved: the material accelerated by the inner rotating blade shaft directly impacts the wear-resistant shaft and cylinder liner around the circumference of the outer rotating cylinder. The counter-rotating outer rotating cylinder increases the impact force between the cylinder liner and the material accelerated by the inner rotating blade shaft, and also increases the number of impacts between the wear-resistant shaft and the material accelerated by the inner rotating blade shaft, with the impact direction in the same direction as the wear-resistant shaft. The radial direction of the grinding shaft thus achieves the function of crushing and sand making (fine sand); when the outer rotating cylinder rotates in the opposite direction to the inner rotating blade shaft, the function of crushing, sand making and shaping can be achieved: the material accelerated by the inner rotating blade shaft directly impacts the wear-resistant shaft and cylinder liner of the outer rotating cylinder. The opposite rotation of the outer rotating cylinder makes the impact force between the cylinder liner and the material accelerated by the inner rotating blade shaft greater. The opposite rotation of the outer rotating cylinder makes the wear-resistant shaft impact the material accelerated by the inner rotating blade shaft more times and the impact direction with the material is in the radial direction of the wear-resistant shaft, thus achieving the function of crushing, sand making and shaping.

[0050] During operation, the adjustment of the lead screw and positioning nut compensates for running wear and installation errors, making the contact rate between the outer rotating cylinder and the main frame more suitable. The appropriate running clearance and oil film thickness are determined by adjusting the clearance plate. Lubricating oil is supplied to the sliding joint surface through the lubrication channel of the flange plate to ensure smooth and abnormal operation. The lubrication channel supplies oil to the annular slide, forming a thicker and more stable oil film at the joint surface, allowing the outer rotating cylinder to float and rotate on the main frame, reducing losses and saving motor power.

[0051] The hydraulic system uses hydraulic valves and an electrical control system to control the hydraulic motor assembly of the outer rotating cylinder to achieve various motion states, such as stop, high-speed same-direction rotation, slow same-direction rotation, high-speed reverse rotation, and slow reverse rotation, making adjustment more convenient and faster.

[0052] The lubrication system delivers the hydraulic oil required by the equipment at the contact surfaces of the upper and lower rolling bearings and sliding rings of the conveyor belt, reducing equipment wear and lowering bearing temperature, thus extending the equipment's service life and increasing output.

[0053] The electrical control system integrates multiple functions of equipment production; it can automatically adjust the speed and action of the equipment by inputting the required production process information, and realize functions such as crushing, crushing and shaping, crushing and sand making (coarse sand), crushing and sand making (fine sand), and crushing and sand making and shaping.

[0054] Finally, it should be noted that: the preferred embodiments of this patent have been described in detail above, but this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
