[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] First embodiment Fan blades are usually made of composite materials, plastics, resins and other materials. Under modern technology, these materials can be crushed to recover some energy or converted into new materials after reprocessing. The traditional crushing method is to segment the waste fan blades and transport them to the processing center for unified crushing, but this process will waste a lot of resources and increase the recycling cost. In order to save the subsequent crushing time and energy consumption and improve the recovery rate of fan blades, refer to Figure 1 - Figure 3 The present embodiment provides a vehicle-mounted fan blade crushing device for resource recycling, which is composed of a drum crushing mechanism 1, an automatic feeding mechanism 2 and a trailer platform 3. The drum crushing mechanism 1 and the automatic feeding mechanism 2 are both installed on the trailer platform 3, so that the waste fan blades can be crushed while being transported, so that the crushing device has higher mobility and application range. After being disassembled, the waste fan blades will be cut into appropriate lengths and segmented for subsequent transportation and processing.

[0021] In order to lift the drum crushing mechanism 1 to a certain angle during feeding and improve the recovery rate of the fan blades, the trailer platform 3 includes a trailer bogie 301 arranged at the bottom of the drum frame 105, and one end of the bottom of the drum frame 105 is movably hinged to the trailer bogie 301, so that the entire crushing device has the ability to steer and brake. A hydraulic rod 302 for driving the drum frame 105 to rise and fall is fixedly installed on the top of the trailer bogie 301, which can lift the drum crushing mechanism 1 and ensure the uniformity of the feed distribution. A shock absorbing mechanism 303 is also provided at the bottom of the trailer bogie 301. The shock absorbing mechanism 303 ensures the safety of the entire trailer bogie 301 in driving under various complex road conditions. Although the shock absorption process will cause the drum crushing mechanism 1 to lose a small amount of kinetic energy, it makes the trailer bogie 301 safer and more stable during driving.

[0022] The drum crushing mechanism 1 is used to convert the potential energy generated by the trailer platform 3 into kinetic energy to crush the waste fan blades, which can save subsequent crushing time and energy consumption, thereby solving the problem of resource waste. The drum crushing mechanism 1 includes a drum frame 105 fixed on the trailer bogie 301, and a drum 108 arranged on the inner side of the drum frame 105. The inner wall of the drum 108 is also fixed with a spiral blade 104. The spiral blade 104 rotates with the drum 108, which can crush the material more evenly. A motor 101 is fixedly installed at one end of the drum frame 105, and the output shaft of the motor 101 is connected to the motor 101. A transmission shaft 113 is connected, and the transmission shaft 113 is a stepped shaft, which is reliably fixed, easy to disassemble and assemble, and can withstand a large axial force. The transmission shaft 113 penetrates the drum 108 and extends to the inner side thereof. Both ends of the inner side of the drum 108 are rotatably connected to the transmission shaft 113 through bearings. A plurality of equally spaced crushing tools 111 are detachably provided on the transmission shaft 113. The crushing tools 111 wear out after long-term use and can be disassembled for replacement. When the trailer platform 3 is traveling, the motor 101 first provides an initial power, which can drive the drum 108 and the crushing tool 111 to rotate synchronously in the opposite direction.

[0023] When the trailer platform 3 is traveling on an uneven road, there will be a height difference between its left and right rows of wheels, which will inevitably cause the trailer platform 3 to shake up and down in an unbalanced manner during driving. Such shaking can cause the drum 108 to rotate in different directions (counterclockwise or clockwise). Since the transmission shaft 113 of the drum 108 and the crushing tool 111 is connected through a high-tooth ratio planetary gear 116, as long as the drum 108 rotates a little, the transmission shaft 113 will rotate multiple circles in a full circle, and the transmission shaft 113 drives the crushing tool 111 to rotate to crush the blades, thereby converting the potential energy generated by the shaking of the drum crushing mechanism 1 into kinetic energy that drives the drum 108 and the crushing tool 111 to rotate synchronously.

[0024] When the trailer platform 3 is traveling, the motor 101 provides initial power to rotate the roller 108. When the trailer platform 3 enters an uneven road surface, the power of the motor 101 is cut off, and the roller 108 rotates completely due to the uneven road surface, thereby achieving the purpose of crushing. In this crushing process, there is no need to turn on the motor 101 to cooperate in providing power, because the direction of rotation of the roller 108 caused by the uneven road surface changes randomly, while the direction of rotation of the roller 108 driven by the motor 101 is certain, which will cause the roller 108 to rotate freely in the opposite direction to the direction of rotation of the roller 108 driven by the motor 101, which will greatly reduce the crushing effect and even cause damage to the motor 101. When the trailer platform 3 enters a flat road surface, such as a high-speed road surface, the effect of the free rotation of the roller 108 caused by the uneven road surface is reduced. At this time, the motor 101 can be turned on to provide power, so that the crushing is uninterrupted, saving time cost, so as to achieve the intermittent power supply of the motor 101, without driving all the time, saving energy consumption.

[0025] In order to improve the crushing effect of the waste fan blades, a coupling 102 is connected to the output shaft of the motor 101, and one end of the coupling 102 is provided with a planetary frame 114 fixed to the drum frame 105, and the planetary frame 114 is provided with a limiter 115 sleeved on the outside of the transmission shaft 113. A drum gear ring 103 is fixed to one end of the drum 108, and a planetary gear 116 is meshed on the inner side of the drum gear ring 103. The planetary gear 116 includes a driving gear fixed to the transmission shaft 113, and a planetary gear 116 is meshed on the outer side of the driving gear. There are three driven gears distributed in a circular array meshing with the drum gear ring 103, and the driven gears are rotatably connected to the limiter 115 through bearings. When the transmission shaft 113 drives several crushing tools 111 to rotate at the same time, the drum 108 is also driven to rotate through the planetary gear 116 and the drum gear ring 103. Due to the characteristics of the planetary gear 116, the crushing tool 111 and the drum 108 can be kept rotating in opposite directions at the same time, so that the crushing tool 111 can crush the waste fan blades more evenly.

[0026] A material port cover 110 is hingedly provided at one end of the drum 108 away from the motor 101, and the material port cover 110 is used to seal the material port of the drum 108. Two positioning plates 117 of different heights are fixed on the drum 108, and an automatic positioner 107 matching the positioning plates 117 is fixed on the drum frame 105. The two positioning plates 117 are respectively used to position the drum 108 through the automatic positioner 107 during feeding and discharging, and the length of the automatic positioner 107 is controlled to obtain material ports in different directions; when feeding, the material port of the drum 108 opens upward, and when discharging, the material port of the drum 108 opens on the side.

[0027] In order to ensure the stability of the roller 108 during operation, a positioning gear ring is fixed at one end of the roller 108, and a plurality of positioning gears 109 distributed in a circular array are meshed on the positioning gear ring. The roller 108 drives the positioning gear ring to rotate on the positioning gear 109 to ensure the stability of the rotation of the roller 108. A support 1 fixed to the roller frame 105 is rotatably provided on the positioning gear 109 through a bearing. An annular slide rail is fixed to the other end of the roller 108, and a plurality of positioning rollers 106 distributed in a circular array are rotatably provided on the annular slide rail. A support 2 fixed to the roller frame 105 is rotatably provided on the positioning roller 106 through a bearing. The annular slide rail of the roller frame 105 rotates between the plurality of positioning rollers 106, which can ensure that the roller 108 has axial support force when it is tilted at a certain angle.

[0028] Second embodiment In order to realize automatic feeding into the drum 108 without manual intervention, saving time and labor costs, refer to Figure 4 - Figure 5 In this embodiment, on the basis of the first embodiment, an automatic feeding mechanism 2 for automatically adding fan blades is further provided at one end of the trailer platform 3. The specific implementation method is that the automatic feeding mechanism 2 includes a material barrel 202 arranged at one end of the trailer platform 3, and the segmented fan blades are placed in the material barrel 202. A lifting mechanism fixed to the trailer platform 3 is provided on one side of the material barrel 202, and a turning frame for driving the material barrel 202 to pour out the material is provided on the lifting mechanism. A material barrel baffle 201 fixed to the turning frame is provided on one side of the top of the material barrel 202, and a material barrel grab hook 203 for limiting the position of the material barrel 202 is provided on one side of the top of the turning frame.

[0029] When feeding, firstly, one end of the drum crushing mechanism 1 is lifted to a certain height by the hydraulic rod 302, so that the drum 108 forms a certain angle with the horizontal plane to avoid the accumulation of fan blades at the material port during feeding. Then, the material barrel 202 is lifted to a suitable height by the lifting mechanism, and then the material barrel 202 is rotated to a certain angle by the turning frame, so that the fan blades fall into the drum 108 through the material port.

[0030] The present invention drives the drum crushing mechanism 1 to move through the trailer platform 3, causing the drum crushing mechanism 1 to shake and generate potential energy, and the generated potential energy is converted into kinetic energy for driving the drum 108 and the crushing tool 111 to rotate synchronously in the opposite direction, thereby crushing the waste fan blades in the drum 108, saving subsequent crushing time and energy consumption, and reducing the processing cost of the waste fan blades.

[0031] A control panel electrically connected to the motor 101, hydraulic rod 302, automatic positioner 107, lifting mechanism and turning frame is also installed on the roller frame 105 by bolts. The control panel can control the motor 101, hydraulic rod 302, automatic positioner 107, lifting mechanism and turning frame to operate independently.

[0032] During the actual use of the crushing device, the waste fan blades are added into the drum 108 through the material opening, and then the material opening cover plate 110 is closed, and the trailer platform 3 can be set off, and the motor 101 is turned on at the same time. The output shaft of the motor 101 drives the transmission shaft 113 to rotate through the coupling 102, and the transmission shaft 113 drives a plurality of crushing tools 111 to rotate inside the drum 108. At the same time, the transmission shaft 113 drives the driving gear to rotate, and the driving gear drives the drum gear ring 103 to rotate through the driven gear meshing with it, and the drum gear ring 103 drives the drum 108 to rotate, and the crushing tools 111 and the drum 108 can keep rotating in opposite directions at the same time, so as to crush the waste fan blades more evenly.
