Description

Technical Field

[0001] The utility model relates to the technical field of production and processing of road engineering materials, in particular to a bagasse fiber shearing device. Background Art

[0002] Asphalt pavement is the main pavement form for high-grade highways and urban roads in my country. Fibers added to asphalt pavement have the functions of reinforcement, adsorption and absorption of asphalt, stabilization, viscosity enhancement, toughening and crack resistance, etc., which can reduce water damage to the pavement, delay reflective cracks, improve high temperature stability and low temperature crack resistance, etc., which is of great significance to improving the performance of the pavement and extending its service life. At present, the commonly used fibers for asphalt pavement include wood fiber, basalt fiber and polymer fiber, among which wood fiber belongs to plant fiber and is widely used because of its advantages of non-toxicity, odorlessness, pollution-free and non-radioactivity. However, wood fiber is mainly made of wood as raw material, and seeking new fibers that meet the requirements of asphalt pavement has become a hot topic in the field of road engineering.

[0003] Sugarcane is an important raw material for sugar production. Bagasse is a renewable and cheap plant fiber raw material. Recycling bagasse to prepare asphalt pavement fiber has high fiber output rate, simple preparation process and low production cost. It can increase the high added value of bagasse, reduce the dependence of asphalt pavement engineering on lignin fiber and the consumption of wood, and open up a new way for environmentally friendly use of bagasse. Bagasse fiber for asphalt pavement has strict requirements on indicators such as pass rate and oil absorption rate. However, these technical indicators are directly related to bagasse fiber processing equipment. The preparation method of bagasse fiber is mainly wet method, which requires soaking bagasse in water in advance, and then wet bagasse and water are put into the device for processing and shearing according to a certain proportion. At present, the commonly used equipment such as grinding disc grinder, vertical disc claw crusher and hammer crusher in the market are limited to shearing and crushing dry materials. The bagasse fiber used for preparation is of poor quality, low efficiency, and the technical indicators do not meet the relevant specifications. Small blade grinders are used to grind medicinal materials, rice and other edible dry foods. By adopting appropriate preparation process parameters, bagasse fibers that meet the specifications can be processed. However, the fiber quality is unstable, the production efficiency is low, and the motor is prone to mechanical damage due to water seepage, which may even cause safety problems. Therefore, it is only suitable for indoor experimental research that requires processing a small amount of fiber.

[0004] The utility model proposes a bagasse fiber shearing device, which improves the quality stability of bagasse fiber, improves the shearing efficiency of bagasse fiber, avoids water from entering the motor during processing, and improves the service life and safety of the device by adjusting the motor position, increasing the motor power, expanding the device container, and optimizing the blade mechanism.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0022] First embodiment:

[0023] See also Figures 1 to 5 ,in Figure 1 This is a schematic diagram of the overall structure of the bagasse fiber shearing device of the first embodiment of the utility model. Figure 2 This is a schematic diagram of the structure of the gearbox 121 of the first embodiment of the utility model installed on the bottom plate 108. Figure 3 1 is a schematic cross-sectional view of the blade assembly 107 according to the first embodiment of the utility model.

Figure 5 It is a cross-sectional schematic diagram along the shock-absorbing spring 112 of the first embodiment of the utility model. The utility model provides a bagasse fiber shearing device, including a supporting mechanism, a power mechanism, a control mechanism and a shearing mechanism. The shearing mechanism includes a hollow cylinder 101, a feed port 102, a discharge port 103, a driven wheel 104, a high-speed bearing 105, a main shaft 106 and a blade group 107. The supporting mechanism includes a bottom plate 108, a vertical supporting bracket 109, a supporting plate 110, a fixed block 111, a shock-absorbing spring 112, a movable block 113, a universal wheel 114, a hydraulic cylinder 115, a telescopic rod 116 and a fixed pad 117. The power mechanism includes a motor 118, a driving wheel 119 and a connecting belt 120. The control mechanism includes a gearbox 121, a timer 122 and a switch 123.

[0024] In this embodiment, the utility model connects a plurality of arc-shaped cutters with single cutting edges to the main shaft 106 to form a blade group 107, thereby ensuring effective cutting of bagasse fiber, further improving the quality of bagasse fiber, reducing quality volatility, and thereby greatly improving the processing efficiency of bagasse fiber. At the same time, by using 3Cr13 stainless steel to prepare the blade group 107, the heating problem of the cutter during the processing and production of bagasse fiber is solved. In addition, since the blades of the blade group 107 adopt reasonable cutting edge angles and thicknesses, the problem of difficulty in coordinating the cutting efficiency and life of the cutter is solved. In addition, the position of the motor is optimized, and belt power is transmitted, which solves the problem of water entering the motor during the preparation of bagasse fiber, thereby improving the service life and safety of the device.

[0025] Among them, the supporting mechanism is used to support the shearing mechanism, the power mechanism provides power for the shearing mechanism, and the control mechanism is used to control the shearing mechanism. The feed port 102 and the discharge port 103 are respectively connected to the hollow cylinder 101 and are respectively located on the upper and lower surfaces of the hollow cylinder 101. The two ends of the main shaft 106 are connected with the high-speed bearings 105 and pass through the hollow cylinder 101. The driven wheel 104 is arranged on the outside of the main shaft 106 on the left side. The blades of the blade group 107 are evenly arranged on the outside of the main shaft 106. The material of the blades of the blade group 107 is 3Cr13 stainless steel. A discharge port 103 is arranged near the discharge port 103. A control switch 123 and a discharging rotating handle are provided, so that the discharging of the bagasse fiber obtained after crushing can be automatically controlled by clicking the discharging control switch 123 or the discharging rotating handle can be manually operated to manually control the discharging of the bagasse fiber obtained after crushing. The blade group 107 includes a first blade and a second blade. The length of the first blade is longer than that of the second blade. The first blade and the second blade are both fixedly mounted on the outside of the main shaft 106 by bolts, so that the first blade or the second blade can be replaced after being worn. The hollow cylinder 101 is provided with a maintenance window 124. The maintenance window 124 is opened to facilitate the replacement of the first blade or the second blade after being worn.

[0026] Secondly, the base plate 108 is arranged on the lower surface of the hollow cylinder 101; the vertical support bracket 109 is fixed on the outer side of the high-speed bearing 105 and is arranged on the upper surface of the base plate 108; the support plate 110 is fixed on the outer side of the base plate 108 and the vertical support bracket 109, and the number of the vertical support brackets 109 is two, which are respectively located on the left and right sides above the base plate 108, and the hollow cylinder 101 is located between the two vertical support brackets 109.

[0027] Again, the fixed block 111 is fixed on the lower surface of the bottom plate 108; the shock-absorbing spring 112 is fixed on the inner side of the fixed block 111; the movable block 113 is fixed on the lower surface of the shock-absorbing spring 112 and is located on the inner side of the fixed block 111; the universal wheel 114 is movably connected with the movable block 113 and is located on the lower surface of the movable block 113. The fixed block 111 is a structure with an opening at the lower end and a hollow interior. The movable block 113 and the shock-absorbing spring 112 are both located in the fixed block 111. The shock-absorbing spring 112 is provided with a damper, so that when the shock-absorbing spring 112 shakes, the damper on the shock-absorbing spring 112 will generate a damping force to prevent the shock-absorbing spring 112 from shaking, thereby making the shock-absorbing spring 112 The shaking will eventually stop and will not keep shaking. When the movable block 113 moves up and down in the fixed block 111, the shock-absorbing spring 112 will expand and contract in the fixed block 111. Since the shock-absorbing spring 112 has a self-recovery effect, when the expansion and contraction force on the shock-absorbing spring 112 disappears, the shock-absorbing spring 112 will drive the movable block 113 to move in the fixed block 111 in the direction of returning to its original position, and then the shock-absorbing spring 112 will buffer the up and down movement of the movable block 113 in the fixed block 111. Through the horizontal and vertical rotation of the universal wheel 114 under the base plate 108, the universal wheel 114 can move in all directions on the ground, front, back, left, and right.

[0028] At the same time, the hydraulic cylinder 115 is fixed on the lower surface of the base plate 108; the telescopic rod 116 is connected to the output end of the hydraulic cylinder 115 and is located on the lower surface of the hydraulic cylinder 115; the fixed pad 117 is fixed to the lower end of the telescopic rod 116, and the output end of the hydraulic cylinder 115 is connected to the telescopic rod 116, and drives the telescopic rod 116 to retract, thereby driving the fixed pad 117 to move up and down under the base plate 108. The material of the fixed pad 117 is rubber material, and the friction force of the fixed pad 117 is large, so that when the fixed pad 117 contacts with the ground, the friction force between the fixed pad 117 and the ground is large, thereby increasing the stability of the shearing device supporting on the ground.

[0029] In addition, the motor 118 is fixed on the upper surface of the support plate 110; the driving wheel 119 is connected to the output end of the motor 118 and is located on a side of the motor 118 close to the driven wheel 104; the connecting belt 120 is movably connected to the driving wheel 119 and the driven wheel 104 respectively, and is located on the outer sides of the driving wheel 119 and the driven wheel 104. The output end of the motor 118 is connected to the driving wheel 119 and drives the driving wheel 119 to rotate along its own axis. The driving wheel 119 and the driven wheel 104 are connected through the connecting belt 120, so that the rotation of the driving wheel 119 along its own axis can drive the driven wheel 104 to rotate along its own axis, and then drive the main shaft 106 to rotate along its own axis inside the high-speed bearing 105. The transmission ratio of the connecting belt 120 is 2:1.

[0030] In addition, the gearbox 121 is electrically connected to the motor 118 and is arranged on the upper surface of the support plate 110; the timer 122 is electrically connected to the gearbox 121 and is arranged on the upper surface of the gearbox 121; the switch 123 is electrically connected to the motor 118 and is arranged on the upper surface of the gearbox 121, the gearbox 121 can control the motor 118, thereby controlling the rotation speed of the shearing device, the timer 122 can record the processing time of the shearing device, and the switch 123 can start and stop the motor 118.

[0031] Finally, the blades of the blade set 107 are evenly arranged on the outside of the main shaft 106 by bolt connection, the thickness of the blades of the blade set 107 is 4-6 mm, the edge angle is 15-20°, and the material of the main shaft 106 is stainless steel.

[0032] When using a bagasse fiber shearing device of the present embodiment, when the shearing device needs to be moved, the hydraulic cylinder 115 is started, so that the power output from the output end of the hydraulic cylinder 115 drives the telescopic rod 116 to be extended and retracted, thereby driving the fixed pad 117 to move up and down under the bottom plate 108. When the height of the lowest point of the fixed pad 117 is higher than the height of the lowest point of the universal wheel 114, the fixed pad 117 no longer supports the bottom plate 108, but the universal wheel 114 supports the bottom plate 108. Then, the universal wheel 114 is made to rotate horizontally and vertically under the movable block 113, so that the universal wheel 114 can drive the bottom plate 108 to move in all directions above the ground, front and back, left and right, and then the shearing device can be moved to a specified position. When the universal wheel 114 is hit or encounters a pothole during the movement, the universal wheel 114 will be impacted and shake up and down, thereby driving the movable block 113 to move up and down in the fixed block 111. The movable block 113 moves up and down in the fixed block 111, thereby driving the shock absorbing spring 112 to expand and contract in the fixed block 111. Since the shock absorbing spring 112 has a self-restoring effect, the shock absorbing spring 112 can buffer the up and down movement of the movable block 113 in the fixed block 111, and then the shock absorbing spring 112 can buffer the up and down movement of the bottom plate 108, so as to avoid the electrical components in the shearing device from being damaged by following the up and down movement of the bottom plate 108. When at the designated position, the fixed pad 117 is allowed to move up and down under the base plate 108. When the lowest point of the fixed pad 117 is lower than the lowest point of the universal wheel 114, the universal wheel 114 no longer supports the base plate 108, but the fixed pad 117 supports the base plate 108, so that the base plate 108 is fixed above the ground, thereby fixing the shearing device. At this time, the friction between the fixed pad 117 and the ground is relatively large, thereby increasing the stability of the shearing device in supporting the ground.

[0033] When the bagasse is sheared, the bagasse is first pre-treated to remove the impurities in the bagasse, and then soaked in water for 10-12 hours for use. Then, the bagasse is sheared by a shearing device, the soaked bagasse is fished out, and after the water is dried, the bagasse is put into the hollow cylinder 101 from the feed port 102 in a mass ratio of bagasse: water = 1:3, and the switch 123 is operated so that the switch 123 can control the start and stop of the motor 118, and the shearing time is set to 2 minutes through the timer 122, and the speed of the shearing device is controlled by the gearbox 121. By starting the motor 118, the power output from the output end of the motor 118 drives the driving wheel 119 to rotate along its own axis, and then the connecting belt 12 0 to drive the driven wheel 104 to rotate along its own axis, and through the rotation of the driven wheel 104 along its own axis, the main shaft 106 can be driven to rotate along its own axis inside the high-speed bearing 105, and then the blade group 107 outside the main shaft 106 can be driven to rotate along its own axis in the hollow cylinder 101, so as to achieve shearing of the bagasse in the hollow cylinder 101. After the bagasse is sheared, the discharging control switch 123 is popped out, and the discharging rotating handle is controlled to pour the mixed slurry of bagasse and water from the discharging port 103. Finally, the mixed slurry of bagasse and water obtained by shearing is subjected to post-processing, and the mixed slurry of bagasse and water is subjected to processes such as dehydration, modification, drying, and screening, so as to finally obtain the desired bagasse fiber.

[0034] When the first blade or the second blade of the blade set 107 is worn, the maintenance window 124 is removed from the inner side of the hollow cylinder 101, so that the internal space of the hollow cylinder 101 is opened. At this time, the bolt can be removed from the outer side of the main shaft 106, so that the first blade or the second blade of the blade set 107 can be removed from the outer side of the main shaft 106, so as to facilitate the replacement of the first blade or the second blade of the blade set 107.

[0035] In summary, the utility model connects multiple arc-shaped knives with single cutting edges to the main shaft 106 to form a blade group 107, thereby ensuring effective cutting of bagasse fiber, further improving the quality of bagasse fiber, reducing quality volatility, and greatly improving the processing and production efficiency of bagasse fiber. At the same time, by using 3Cr13 stainless steel to prepare the blade group 107, the heating problem of the knife in the processing and production of bagasse fiber is solved. In addition, since the blades of the blade group 107 adopt reasonable cutting angles and thicknesses, the problem of difficult coordination between the cutting efficiency and life of the knife is solved. In addition, the position of the motor is optimized, and the belt is used to transmit power, which solves the problem of water entering the motor during the preparation of bagasse fiber, and improves the service life and safety of the device. Finally, the effective space for processing and producing bagasse fiber of the shearing device adopted by the utility model is significantly increased, and the processing and production efficiency is further improved. The speed of the motor is automatically controlled by the adaptive gearbox 121, thereby reducing energy consumption and reducing production costs, thereby solving the technical problems of large quality fluctuations, low production efficiency, short service life of the device and insufficient safety of the bagasse fiber prepared by the existing shearing device.
