[0002] With the rapid development of the photovoltaic industry, the recycling and treatment of a large number of waste photovoltaic components including glass, silicon materials and metals has become an important environmental protection issue.

[0003] In order to effectively separate and recycle waste photovoltaic modules, they need to be crushed. In existing crushers, an integrated blade is usually used to meet the requirements of large torque so that the cutter disc and the cutter head that make up the blade are formed in one piece. During the crushing operation, the blade is driven by the main shaft and the cutter head that is integrated on the outer edge of the blade directly contacts the waste photovoltaic modules for cutting and crushing.

[0004] However, the inventors have found that the prior art has disadvantages.

Summary of the invention

[0012] In some embodiments, in the aforementioned blade, a groove extending to the first end is formed on the first side surface facing away from the blade disc, and the groove is filled with a hard material, and the hardness of the hard material is greater than that of the blade surface.

[0013] In some embodiments, the aforementioned blade, wherein a first through hole is provided at a connection position between the second blade spacing groove and the blade surface relative to the second side surface; a second through hole is provided at the first blade corresponding to the first through hole, and both the first through hole and the second through hole can be penetrated by fasteners so that the second blade head can be detachably connected to the blade surface of the first blade head.

[0014] A second aspect of the present application provides a movable blade structure, comprising:

[0015] Spindle;

[0016] The blade assembly is sleeved on the main shaft. The blade assembly includes a plurality of the above-mentioned blades. The plurality of blades are arranged at intervals and the blade discs of the blade bodies of the plurality of blades are sleeved on the main shaft.

[0017] In some embodiments, the aforementioned moving blade structure, wherein there are two blade assemblies and they are respectively a first blade assembly and a second blade assembly, the first blade assembly and the second blade assembly are mirror-set and sleeved on the main shaft; two adjacent blades among the multiple blades of the first blade assembly are relatively rotated by a preset angle along the same rotation direction, so that the multiple second blade heads of the multiple blades are distributed along the first direction, the second blade assembly is mirrored to the first blade assembly so that the multiple second blade heads of the multiple blades are distributed along the second direction, the first direction and the second direction form a second preset angle on the first side surface of the second blade head, and the second preset angle is an obtuse angle.

[0018] In some embodiments, in the aforementioned movable blade structure, the second preset angle is 170° to 177°.

[0019] In some embodiments, in the aforementioned movable blade structure, a second preset gap is provided between two second blade heads of two blades of the first blade assembly and the second blade assembly that are close to each other.

And because the hardness of the first side surface is greater than the blade face, it has a longer service life in the crushing operation scenario, and with the support of greater hardness, it can also improve the crushing efficiency and thus reduce the energy consumption of the crushing operation. And because the second blade head is detachably connected to the blade face, it is also easy to replace the additional second blade head, reducing the maintenance cost.

[0046] Embodiment 1

[0047] like Figure 1 and Figure 2As shown, the first aspect of the present application provides a blade 1, including a blade body 11 and a second cutting head 12; the blade body 11 includes an integrally formed cutting disc 111 and a plurality of first cutting heads 112, the plurality of first cutting heads 112 protrude from the outer edge of the cutting disc 111 and have a cutting surface 1121, and the cutting disc 111 can be sleeved on the main shaft 2; the second cutting head 12 is detachably connected to the cutting surface 1121, and the first side surface 121 of the second cutting head 12 facing away from the cutting surface 1121 has a harderness than the cutting surface 1121.

[0048] Specifically, the blade 1 provided in the first aspect of the present application includes a blade body 11 and an additional second blade head 12. Among them, in order to meet the use requirements of large torque during the crushing operation, the blade body 11 includes an integrally formed cutter disc 111 and a plurality of first blade heads 112, and the plurality of first blade heads 112 are arranged protruding from the outer edge of the cutter disc 111, as a component for crushing and cutting on the blade body 11. The first blade head 112 has a variety of different shapes and styles, such as a blade blade head, a claw blade head, a hammer blade head, etc., which are not specifically limited. And in order to meet the use requirements, the first blade head 112 has a blade surface 1121 so that the blade surface 1121 can be used to crush and cut the waste photovoltaic components during the rotation of the blade body 11. It should be noted that the blade surfaces 1121 of multiple blade heads need to be arranged in the same direction so that during the rotation of the blade 1, multiple blade surfaces 1121 can all play a role in crushing and cutting. In this application, the number of first blade heads 112 integrally formed with the cutter disc 111 is not limited, and is adjusted according to actual use requirements.

[0049] In order to prevent the blade surface 1121 of the first blade head 112 from directly contacting the waste photovoltaic components with greater hardness for crushing operations, the blade 1 provided in the present application is additionally provided with a second blade head 12, and the second blade head 12 is detachably connected to the blade surface 1121. The first side surface 121 of the second blade head 12 facing away from the blade surface 1121 contacts the waste photovoltaic components during the crushing operation, thereby protecting the first blade head 112, and the detachable connection makes it easy to replace the second blade head 12, thereby reducing the maintenance cost of the blade 1.

[0050] The first side surface 121 replaces the blade surface 1121 to contact the waste photovoltaic components during the rotation of the blade 1. The present application sets the first side surface 121 of the second blade head 12 away from the blade surface 1121 to have a harder hardness than the blade surface 1121, so that it has a longer service life in the crushing operation scenario, and with the support of greater hardness, it can also improve the crushing efficiency and thus reduce the energy consumption of the crushing operation. The second blade head 12 can be made of a material with a harder hardness than the blade surface 1121 as a whole, so that its first side surface 121 has a harder hardness than the blade surface 1121; or a material with a higher hardness can be added to the first side surface 121 of the second blade head 12 away from the blade surface 1121 by means of laser welding, high-temperature melting, etc., so that the hardness of the first side surface 121 is greater than that of the blade surface 1121, and there is no specific limitation. For example: in one embodiment, the material of the integrally formed cutter disc 111 and the first cutter head 112 of the present application is stainless steel, and the second cutter head 12 is made of high-speed tool steel; in another embodiment, the material of the integrally formed cutter disc 111 and the first cutter head 112 of the present application is low alloy steel, and the first side surface 121 of the second cutter head 12 is provided with hard alloy by high temperature melting. The present application does not limit the specific material of the blade body 11 and the second cutter head 12, as long as the hardness of the first side surface 121 of the second cutter head 12 is greater than the blade surface 1121 of the first cutter head 112, so as to increase the service life, improve the crushing efficiency and thus reduce the energy consumption of the crushing operation.

[0051] In a first aspect, the present application provides a blade 1, comprising a blade body 11 and a second blade head 12; the blade body 11 comprises an integrally formed blade disc 111 and a plurality of first blade heads 112, the plurality of first blade heads 112 protrude from the outer edge of the blade disc 111 and have a blade surface 1121, and the blade disc 111 can be sleeved on the main shaft 2; the second blade head 12 is detachably connected to the blade surface 1121, and the first side surface 121 of the second blade head 12 facing away from the blade surface 1121 has a harderness than the blade surface 1121. The present application adds a second blade head 12 to the plurality of first blade heads 112 integrally formed with the blade disc 111 in the blade body 11, thereby avoiding the blade surface 1121 of the first blade head 112 from directly contacting the waste photovoltaic components with a relatively large hardness for crushing operations, and the first blade head 112 is protected by the first side surface 121 of the added second blade head 12 facing away from the blade surface 1121 from contacting the waste photovoltaic components. And because the hardness of the first side surface 121 is greater than that of the blade surface 1121, it has a longer service life in the crushing operation scenario, and with the support of greater hardness, it can also improve the crushing efficiency and thus reduce the energy consumption of the crushing operation. And because the second blade head 12 is detachably connected to the blade surface 1121, the additional second blade head 12 is also easy to replace, reducing maintenance costs. Through the application of this application, the problem that the blade head of the integrated blade in the existing crusher is prone to wear due to the greater hardness of the waste photovoltaic modules, thereby reducing the crushing efficiency, increasing energy consumption, and the high replacement cost is solved.

[0052] like Figure 1 and Figure 2 As shown, in some embodiments, the side of the second cutting head 12 close to the cutting surface 1121 has a second side surface 122 opposite to the first side surface 121, and the end of the first side surface 121 away from the cutting disc 111 is more protruding than the end of the second side surface 122 away from the cutting disc 111, so that the end surface of the first end 123 of the second cutting head 12 away from the cutting disc 111 has a first preset angle R1 with the first side surface 121, and the first preset angle R1 is an acute angle.

[0053] Specifically, the present application sets the end of the first side 121 facing away from the cutter disc 111 to be more protruding than the end of the second side 122 facing away from the cutter disc 111, so that the end face of the first end 123 of the second blade head 12 has a first preset angle R1 with the first side 121, and the first preset angle R1 is an acute angle. Under the action of the first preset angle R1, the first end 123 of the second blade head 12 can contact the waste photovoltaic components with a smaller contact area on the side close to the first side 121 during the crushing operation, thereby reducing the friction generated between the waste photovoltaic components and the load required to drive the blade 1 to move. The smaller contact area increases the pressure on the waste photovoltaic components on the side close to the first side 121 of the first end 123 of the second blade head 12 when contacting the waste photovoltaic components, thereby achieving a better crushing and cutting effect.

[0054] like Figure 1 and Figure 2 As shown, in some embodiments, the first end 123 protrudes from the end of the first blade head 112 away from the blade disc 111; the second end 124 of the second blade head 12 opposite to the first end 123 has a first preset gap 125 with the blade body 11 to at least partially expose the blade surface 1121.

[0055] Specifically, the present application arranges the first end 123 of the second cutter head 12 to protrude from the end of the first cutter head 112 away from the cutter disc 111, so as to protect the end of the first cutter head 112 through the second cutter head 12, and the first side surface 121 of the second cutter head 12, which has a hardness greater than that of the cutter surface 1121, contacts the waste photovoltaic components during the crushing operation. In order to fully increase the processing efficiency of the blade 1 of the present application on waste photovoltaic components during the rotation process, on the basis that the first end 123 of the second blade head 12 protrudes from the end of the first blade head 112 away from the blade disc 111, the present application sets the second end 124 of the second blade head 12 opposite to the first end 123 to have a first preset gap 125 with the blade body 11, so that part of the blade surface 1121 of the first blade head 112 is exposed in the first preset gap 125, that is, the blade surface 1121 exposed in the first preset gap 125 and the first side surface 121 of the second blade head 12 together constitute the surface that contacts the waste photovoltaic components during the rotation process of the blade 1, thereby enabling the blade 1 of the present application to provide a larger contact area with the waste photovoltaic components during the crushing operation, thereby improving the overall crushing efficiency of the blade 1.

[0056] like Figure 3 As shown, in some embodiments, a groove 1211 extending to the first end 123 is formed on the side of the first side 121 facing away from the blade disc 111 , and the groove 1211 is filled with a hard material 1212 , and the hardness of the hard material 1212 is greater than that of the blade surface 1121 .

[0057] Specifically, in the embodiment of the present application, in order to ensure that the first side surface 121 of the second cutter head 12 has a hardness greater than the blade surface 1121 and save costs, the present application provides a groove 1211 extending to the first end 123 on the side of the first side surface 121 away from the cutter disc 111, and fills the groove 1211 with a hard material 1212 having a hardness greater than the blade surface 1121, so that the first side surface 121 can provide a region having a hardness greater than the blade surface 1121 extending to the first end 123 of the outermost edge of the crushing range of the blade 1, and the region corresponds to the groove 1211 and the hard material 1212 in the groove 1211. The hard material 1212 can be high-speed tool steel, tungsten-based cemented carbide, etc., and the hard material 1212 is connected to the groove 1211 provided on the first side surface 121 of the second cutter head 12 by a high-temperature melting method such as brazing, expansion welding, or laser welding.

[0058] At the same time, the present application maintains the flatness of the first side 121 of the second blade head 12 by opening a groove 1211 on the first side 121 and filling the groove 1211 with a hard material 1212 whose hardness is greater than that of the blade surface 1121, so that the first side 121 can be evenly stressed when facing the impact of the waste photovoltaic components during the crushing operation, thereby ensuring the service life of the second blade head 12. At the same time, the flat first side 121 can stably apply extrusion and shear forces to the waste photovoltaic components as the blade 1 rotates, thereby ensuring the crushing effect and improving the crushing efficiency.

[0059] like Figure 2 As shown, in some embodiments, a first through hole 126 is provided at a connection position between the second side surface 122 and the blade surface 1121 of the second blade head 12 relative to the spacing groove 1211; a second through hole 1122 is provided on the first blade head 112 corresponding to the first through hole 126, and both the first through hole 126 and the second through hole 1122 can be penetrated by fasteners to enable the second blade head 12 to be detachably connected to the blade surface 1121 of the first blade head 112.

[0060] Specifically, in order to achieve a detachable connection between the second cutter head 12 and the blade surface 1121 of the first cutter head 112, the present application provides a first through hole 126 at the connection position between the second side surface 122 and the blade surface 1121 of the second cutter head 12 relative to the spacing groove 1211, and the first cutter head 112 provides a second through hole 1122 corresponding to the first through hole 126. By inserting fasteners such as bolts and pins into the first through hole 126 and the second through hole 1122, the second cutter head 12 is limitedly installed, and the detachable connection of the second cutter head 12 relative to the blade surface 1121 of the first cutter head 112 is also achieved, so that the second cutter head 12 is easy to replace and the maintenance cost is reduced.

[0061] Embodiment 2

[0062] like Figure 4 and Figure 5 As shown, the second aspect of the present application provides a movable blade structure, including a main shaft 2 and a blade assembly 3; the blade assembly 3 is sleeved on the main shaft 2, and the blade assembly 3 includes a plurality of blades 1, the plurality of blades 1 are arranged at intervals, and the blade disc 111 of the blade body 11 of the plurality of blades 1 is sleeved on the main shaft 2.

[0063] Specifically, please refer to the first embodiment for the specific structure of the blade 1, which will not be described in detail here.

[0064] Specifically, the second aspect of the present application provides a movable blade structure, including a main shaft 2 and a blade assembly 3, wherein the blade assembly 3 is sleeved on the main shaft 2, and the main shaft 2 can be driven to drive the blade 1 assembly connected thereto to rotate, thereby crushing and cutting the waste photovoltaic components. In order to meet the crushing requirements, the blade assembly 3 in the present application includes a plurality of blades 1 provided in the present application with a second blade head 12 added thereto, wherein the plurality of blades 1 are arranged at intervals to reduce friction generated when rotating with each other, and the combination of the plurality of blades 1 enables the blade assembly 3 to have a larger operating range for crushing and processing waste photovoltaic components. In one embodiment, multiple spaced blade bodies 11 of multiple blades 1 can be respectively provided with second cutter heads 12. For example, if there are five blades 1 and each blade 1 has five first cutter heads 112, the number of second cutter heads 12 is 25. The second cutter heads 12 can also be provided to correspond to the first cutter heads 112 of multiple blade bodies at the same time. For example, if there are five blades 1 and each blade 1 has four first cutter heads 112, the number of second cutter heads 12 is four so as to simultaneously connect the four first cutter heads 112 of four blade bodies. There is no specific limitation as long as the crushing operation can be completed by the blade assembly 3 including multiple blades 1 driven by the main shaft 2.

[0065] In order to allow the cutter disc 111 of the blade body 11 of multiple blades 1 to be mounted on the main shaft 2, the cutter disc 111 is provided with a mounting hole. In order to effectively prevent the blade 1 from rotating and causing sliding between the cutter disc 111 and the main shaft 2, thereby ensuring the stable operation of the crushing operation, the mounting hole can be in the form of a quadrilateral, hexagon, octagon, etc., or in the form of a spline hole, depending on the form of the main shaft 2, without limitation.

[0066] The second aspect of the present application provides a movable blade structure, including a main shaft 2 and a blade assembly 3; the blade assembly 3 is sleeved on the main shaft 2, and the blade assembly 3 includes a plurality of blades 1, the plurality of blades 1 are arranged at intervals, and the blade bodies 11 of the plurality of blades 1 have a cutter disc 111 sleeved on the main shaft 2. The blade 1 includes a blade body 11 and a second cutter head 12; the blade body 11 includes an integrally formed cutter disc 111 and a plurality of first cutter heads 112, the plurality of first cutter heads 112 protrude from the outer edge of the cutter disc 111 and have a cutter surface 1121, and the cutter disc 111 can be sleeved on the main shaft 2; the second cutter head 12 is detachably connected to the cutter surface 1121, and the first side surface 121 of the second cutter head 12 facing away from the cutter surface 1121 has a harderness than the cutter surface 1121. The present application adds a second blade head 12 to the first blade heads 112 integrally formed with the blade disc 111 in the blade body 11, thereby avoiding the blade face 1121 of the first blade head 112 from directly contacting the waste photovoltaic components with greater hardness for crushing operations, and the first side face 121 of the added second blade head 12 away from the blade face 1121 contacts the waste photovoltaic components, thereby forming protection for the first blade head 112. And because the hardness of the first side face 121 is greater than that of the blade face 1121, it has a longer service life in the crushing operation scenario, and with the support of greater hardness, it can also improve the crushing efficiency and thus reduce the energy consumption of the crushing operation. And because the second blade head 12 is detachably connected to the blade face 1121, it is also easy to replace the added second blade head 12, which reduces the maintenance cost. Through the application of the present application, the problem that the blade head of the integrated blade in the existing crusher is prone to wear due to the greater hardness of the waste photovoltaic components, thereby reducing the crushing efficiency, increasing energy consumption, and the high replacement cost is solved.

[0067] like Figure 4 and Figure 5 As shown, in some embodiments, the blade assembly 3 is divided into two and respectively is a first blade assembly 31 and a second blade assembly 32, the first blade assembly 31 and the second blade assembly 32 are mirror-set and sleeved on the main shaft 2; two adjacent blades 1 among the multiple blades 1 of the first blade assembly 31 are rotated relative to each other by a preset angle along the same rotation direction, so that the multiple second blade heads 12 of the multiple blades 1 are distributed along the first direction A, the second blade assembly 32 is mirrored to the first blade assembly 31 so that the multiple second blade heads 12 of the multiple blades 1 are distributed along the second direction B, the first direction A and the second direction B form a second preset angle R2 on the first side surface 121 of the second blade head 12, and the second preset angle R2 is an obtuse angle.

[0068] Specifically, the present application is provided with a mirror image of a first blade assembly 31 and a second blade assembly 32. While expanding the crushing operation range by increasing the number of blade assemblies 3, the present application distributes the second cutter heads 12 in the first blade assembly 31 and the second blade assembly 32 in different directions. Two adjacent blades 1 in the multiple blades 1 of the first blade assembly 31 are relatively rotated by a preset angle along the same rotation direction, so that the multiple second cutter heads 12 of the multiple blades 1 are distributed along the first direction A. The second blade assembly 32 is mirrored to the first blade assembly 31 so that the multiple second cutter heads 12 of the multiple blades 1 are distributed along the second direction B. The adjacent two blades 1 in the multiple blades 1 are relatively rotated by a preset angle along the same rotation direction. When the preset angle is not 0°, due to the mirror image setting of the first blade assembly 31 and the second blade assembly 32, a second preset angle R2 is formed between the first direction A and the second direction B on the first side 121 of the second blade head 12, and the second preset angle R2 is an obtuse angle. When the first side 121 of the second blade head 12 of the first blade assembly 31 and the second blade assembly 32 in the obtuse angle state contact the waste photovoltaic components together, under the action of the second preset angle R2, the waste photovoltaic components can be gathered toward the mirror symmetry center during cutting, thereby generating a squeezing effect on the waste photovoltaic components between the first blade assembly 31 and the second blade assembly 32, further improving the crushing efficiency. The size of the second preset angle R2 is obtained based on the service life and cutting efficiency experiments of the second blade head 12 of the blade 1 at different angles.

[0069] In some embodiments, the second preset angle R2 is 170° to 177°.

[0070] Specifically, in order to enable the waste photovoltaic components to gather toward the mirror symmetry center of the first blade component 31 and the second blade component 32 when cutting under the action of the second preset angle R2, and at the same time enable the first blade component 31 and the second blade component 32 to expand the crushing operation range, the present application sets the second preset angle R2 to be between 170° and 177°. When the second preset angle R2 is 170°, the first direction A in which the multiple second blade heads 12 of the multiple blades 1 of the first blade component 31 are distributed and the second direction B in which the multiple second blade heads 12 of the multiple blades 1 of the second blade component 32 are distributed form a second preset angle R2 of 170° on the first side 121 of the second blade head 12. When the first side 121 of the second blade head 12 of the first blade component 31 and the second blade component 32 at the second preset angle R2 of 170° contact the waste photovoltaic components together, the waste photovoltaic components can gather toward the mirror symmetry center when cutting, thereby generating a squeezing effect on the waste photovoltaic components between the first blade component 31 and the second blade component 32.

[0071] When the second preset angle R2 is 177°, the first direction A in which the multiple second blade heads 12 of the multiple blades 1 of the first blade assembly 31 are distributed and the second direction B in which the multiple second blade heads 12 of the multiple blades 1 of the second blade assembly 32 are distributed form a second preset angle R2 of 177° on the first side 121 of the second blade head 12. When the first side 121 of the second blade head 12 of the first blade assembly 31 and the second blade assembly 32 at the second preset angle R2 of 177° contact the waste photovoltaic components together, the waste photovoltaic components can be gathered toward the center of mirror symmetry during cutting, and can produce a squeezing effect on the waste photovoltaic components in a larger range than when the second preset angle R2 is 170°.

[0072] like Figure 4 and Figure 5 As shown, in some embodiments, a second preset gap 4 is provided between two second blade heads 12 of two blades 1 close to each other in the first blade assembly 31 and the second blade assembly 32 .

[0073] Specifically, considering that in the process of installing the movable blade structure of the present application on the crusher, it is necessary to adjust the spacing distance of the multiple blades 1 in the first blade assembly 31 and the second blade assembly 32, and it is necessary to ensure that two adjacent blades 1 in the multiple blades 1 of the first blade assembly 31 are relatively rotated by a preset angle along the same rotation direction through adjustment, so that the multiple second blade heads 12 of the multiple blades 1 are distributed along the first direction A, and the second blade assembly 32 is mirrored to the first blade assembly 31 so that the multiple second blade heads 12 of the multiple blades 1 are distributed along the second direction B, so that under the action of the formed second preset angle R2, the waste photovoltaic components can be gathered towards the mirror symmetry center when cutting, and considering that when the crusher has a fixed blade structure that cooperates with the movable blade structure of the present application, the installation of the movable blade mechanism needs to be consistent with the fixed blade When the positions of the structures are calibrated, or when the crusher has multiple sets of moving blade structures, the moving blade structures need to be calibrated with each other. In the present application, there is a second preset gap 4 between the two second cutter heads 12 of the two blades 1 of the first blade assembly 31 and the second blade assembly 32 that are close to each other, so as to avoid the occurrence of a knife collision during the adjustment or calibration process through the reserved second preset gap 4 to protect the components. The second preset gap 4 can be obtained by reserving a certain distance between the two second cutter heads 12 of the two blades 1 of the first blade assembly 31 and the second blade assembly 32 that are close to each other during installation, or by respectively providing inclined surfaces on the side where the two second cutter heads 12 are close to each other, so as to form a second preset gap 4 through the gap between the two inclined surfaces. There is no specific limitation as long as the knife collision can be avoided.

[0074] Embodiment 3

[0075] A third aspect of the present application provides a crusher, comprising a moving blade structure.

[0076] Specifically, please refer to the second embodiment for the specific structure of the movable blade structure, which will not be described in detail here.

[0077] Specifically, the crusher provided in the present application can be an impact crusher with a fixed blade structure matched with a moving blade structure, or it can be a roller crusher with a variety of moving blade structures, etc. The main shaft 2 in the crusher can be placed horizontally or vertically, without limitation, as long as it can realize the crushing operation of waste photovoltaic modules.

[0078] The third aspect of the present application provides a crusher, including a moving blade structure. The moving blade structure includes a main shaft 2 and a blade assembly 3; the blade assembly 3 is sleeved on the main shaft 2, and the blade assembly 3 includes a plurality of blades 1, the plurality of blades 1 are arranged at intervals, and the cutter disc 111 of the blade body 11 of the plurality of blades 1 is sleeved on the main shaft 2. The blade 1 includes a blade body 11 and a second cutter head 12; the blade body 11 includes an integrally formed cutter disc 111 and a plurality of first cutter heads 112, the plurality of first cutter heads 112 protrude from the outer edge of the cutter disc 111 and have a cutter surface 1121, and the cutter disc 111 can be sleeved on the main shaft 2; the second cutter head 12 is detachably connected to the cutter surface 1121, and the first side surface 121 of the second cutter head 12 facing away from the cutter surface 1121 has a harderness greater than that of the cutter surface 1121. The present application adds a second blade head 12 to the first blade heads 112 integrally formed with the blade disc 111 in the blade body 11, thereby avoiding the blade face 1121 of the first blade head 112 from directly contacting the waste photovoltaic components with greater hardness for crushing operations, and the first side face 121 of the added second blade head 12 away from the blade face 1121 contacts the waste photovoltaic components, thereby forming protection for the first blade head 112. And because the hardness of the first side face 121 is greater than that of the blade face 1121, it has a longer service life in the crushing operation scenario, and with the support of greater hardness, it can also improve the crushing efficiency and thus reduce the energy consumption of the crushing operation. And because the second blade head 12 is detachably connected to the blade face 1121, it is also easy to replace the added second blade head 12, which reduces the maintenance cost. Through the application of the present application, the problem that the blade head of the integrated blade in the existing crusher is prone to wear due to the greater hardness of the waste photovoltaic components, thereby reducing the crushing efficiency, increasing energy consumption, and the high replacement cost is solved.
