When the fixed component is installed in place, it will also drive the clamping and closing component to compress and seal the data line of the rotary encoder 110 passing through the protective component, thereby preventing dust from entering the protective component and corroding the rotary encoder 110 during the material picking process of the material picker. When the rotary encoder 110 is maintained and calibrated, the cleaning mechanism 200 can be linked during the disassembly of the fixed component to sweep away the dust and debris accumulated on the top of the protective component, thereby preventing the dust and debris accumulated during the removal of the protective component from falling into the protective component, which increases the trouble of secondary cleaning.

The middle part of the scraper chain track 101 is provided with a pulley block, and the reclaimer tower 103 is fixedly connected to the lower end of the reclaimer tower 103. 03 is fixedly connected with a steel wire rope 102 at the upper end, one end of the steel wire rope 102 passes through the pulley block and is connected with the winding end of the electric hoist above the reclaimer tower 103, a rubber seat 109 is bonded to the inner cavity of the protective shell 106 away from the rubber ring 108, and the rotary encoder 110 is detachably connected to the rubber seat 109, the rotating shaft of the rotary encoder 110 is movably plugged with the middle part of the inner cavity of the pitch hinge shaft 105, and the size of the pitch hinge shaft 105 is adapted to the inner cavity size of the mounting frame 104; The fixing assembly includes a fixing ring 111 arranged in the inner cavity of the protective shell 106, a positioning rod 112 is arranged on the side of the fixing ring 111 close to the rubber ring 108, a plurality of limiting grooves 114 are opened on the inner side of the mounting frame 104, a limiting block 113 is arranged on the side of the positioning rod 112 close to the limiting groove 114, and the limiting block 113 corresponds to the limiting groove 114 one by one, a plurality of rotating frames 115 are fixedly installed in the inner cavity of the protective shell 106, the rotating frame 115 is rotatably connected to the positioning rod 112 through an axle pin, and a first wedge block 117 is arranged on the side of the positioning rod 112 close to the fixing ring 111 A return spring 116 is fixedly installed in the middle of the positioning rod 112, and the other end of the return spring 116 is fixedly connected to the inner wall of the protective shell 106. The first slider 118 is fixedly installed on both the front and rear sides of the fixing ring 111. Both sides of the inner cavity of the protective shell 106 are provided with a strip slide groove 119. The size of the first slider 118 is adapted to the size of the strip slide groove 119, and the first slider 118 is slidably connected to the strip slide groove 119. The number of positioning rods 112 is set to five, and the positioning rods 112 are distributed in a ring shape. The size of the limit block 113 is consistent with the size of the limit groove 114. The pitch angle detection mechanism 100 also includes a driving unit, which includes a rotating rod 125 arranged at the upper end of the protective shell 106, the rotating rod 125 is rotatably connected to the protective shell 106 through a sealed bearing, a first gear 126 is fixedly installed at the lower end of the rotating rod 125, and a rack 127 is fixedly installed on the side of the fixing ring 111 away from the rubber ring 108, the rack 127 is arranged on the rear side of the first gear 126, and the rack 127 is meshed with the first gear 126.

[0034] In this embodiment, the mounting frame 104 is fixedly connected to the lower end of the reclaimer tower 103 by welding, and the first wedge block 117 is fixedly connected to the positioning rod 112 by welding. When protecting, the rotary encoder 110 is first installed in the protective shell 106, and then the rubber ring 108 is placed between the protective shell 106 and the mounting frame 104, and then the rotating shaft of the rotary encoder 110 is inserted into the middle slot of the inner cavity of the pitch hinge shaft 105, and then the rotating rod 125 is rotated clockwise, and the first gear 126 under the rotating rod 125 will drive the rack 127 to move to the right, and the rack 127 drives the fixed ring 111 to follow the movement, and the right edge of the fixed ring 111 will push the first wedge block 117. Then, the plurality of positioning rods 112 are driven to rotate simultaneously, so that the limiting blocks 113 on the plurality of positioning rods 112 rotate into the limiting grooves 114, and the return spring 116 is compressed at the same time. After the right edge of the fixing ring 111 moves from the inclined surface of the first wedge block 117 to the horizontal surface of the first wedge block 117, the limiting block 113 is inserted into the limiting groove 114, so that the protective shell 106 is installed on the front side of the mounting frame 104, and the installation and positioning of the protective shell 106 can be quickly completed only by rotating the rotating rod 125, thereby improving the sealing protection efficiency of the rotary encoder 110. At the same time, the protective shell 106 cooperates with the rubber ring 108 to effectively cover and protect the rotary encoder 110. In addition, the dust such as iron powder and sandstone is prevented from accumulating on the rotary encoder 110 during the material taking process, which may cause erosion on the rotary encoder 110 and affect the accuracy of the rotary encoder 110 in detecting the pitch angle of the side-type material taking machine. In addition, since the fixing ring 111 pushes the multiple positioning rods 112 at the same time, the limit blocks 113 on the multiple positioning rods 112 are simultaneously inserted into the limit grooves 114, thereby ensuring that the clamping force of the protective shell 106 on the rubber ring 108 at multiple positions is consistent. Compared with the use of bolts to install the protective shell 106, the installation efficiency of the protective shell 106 is greatly improved, and the uneven force during the bolt knob rotation process may cause the rubber ring 108 to be damaged and the sealing efficiency to be reduced, thereby improving The sealing and protection effect of the rotary encoder 110 is improved, thereby ensuring the accuracy of the rotary encoder 110 in detecting the pitch angle of the material grabber. Through the setting of the reset spring 116, the positioning rod 112 can be driven to reset after the first wedge block 117 loses its driving force, thereby facilitating the removal of the protective shell 106, and then facilitating the maintenance and calibration of the rotary encoder 110. The first slider 118 cooperates with the strip slide groove 119 to ensure the stability of the movement of the fixing ring 111. Since the size of the mounting frame 104 is consistent with the size of the pitch hinge shaft 105, it is guaranteed that the pitch hinge shaft 105 can rotate stably and will not cause external impurities to enter the mounting frame 104.

[0035] Among them, the clamping and closing assembly includes a connecting rod 120 arranged below the fixing ring 111, and the end of the connecting rod 120 close to the rubber ring 108 is arranged in an arc shape. A receiving groove 128 is provided on the side close to the rubber ring 108 at the lower end of the protective shell 106, and the inner cavity of the receiving groove 128 is symmetrically provided with a fixing frame 121, and the inner cavity of the fixing frame 121 is provided with a rubber pressure block 122, and the two ends of the rubber pressure block 122 are respectively fitted with the inner wall of the receiving groove 128 and the surface of the rubber ring 108, and the inner cavity of the fixing frame 121 is provided with a spring, and the other end of the spring is fixedly connected to the rubber pressure block 122, and a semicircular groove 123 is provided on the inner side of the rubber pressure block 122, and a second wedge block 124 is fixedly installed on the side of the rubber pressure block 122 close to the connecting rod 120.

[0036] In this embodiment, when the fixing ring 111 moves to the right, the fixing ring 111 will drive the connecting rod 120 to move along, and the right end of the connecting rod 120 will push the second wedge block 124, and the second wedge block 124 will drive the rubber pressure block 122 to move toward the middle and stretch the spring at the same time. When the connecting rod 120 moves to the plane of the second wedge block 124, the connecting rod 120 will no longer push the second wedge block 124, so that the semicircular groove 123 on the rubber pressure block 122 is pressed tightly against the outside of the data line of the rotary encoder 110, thereby facilitating the installation of the rotary encoder 110 in the protective shell 106 for protection, and at the same time, the data line of the rotary encoder 110 is pressed and sealed, so as to avoid the dust from entering the protective shell 106 and corroding the rotary encoder 110 during the material reclaiming process of the reclaimer. The setting of 23 can ensure the compression and sealing effect of the rubber pressing block 122 and the data line of the rotary encoder 110, thereby reducing the probability of dust entering. At the same time, since the two ends of the rubber pressing block 122 are respectively in contact with the inner wall of the accommodating groove 128 and the surface of the rubber ring 108, it can be ensured that after the rubber pressing block 122 and the data line of the rotary encoder 110 are compressed and sealed in place, the entire protective shell 106 forms a completely closed state, thereby effectively isolating the external dust from entering the protective shell 106, and the data line of the rotary encoder 110 is compressed and sealed at the same time as the protective shell 106 is installed in place. Compared with using sealant to seal the protective shell 106 and the data line of the rotary encoder 110, the installation efficiency is improved, and it is convenient to remove the protective shell 106 later to maintain and calibrate the rotary encoder 110.

[0037] During use, when adjusting the pitch, the wire rope 102 is wound up by the electric hoist on the reclaimer tower 103, and the wire rope 102 drives the scraper chain track 101 to rotate along the pitch hinge shaft 105. At the same time, the rotation angle of the scraper chain track 101 is detected by the rotary encoder 110 connected to the pitch hinge shaft 105, thereby ensuring the accuracy of the rotation angle of the scraper chain track 101 on the reclaimer. When protecting, first install the rotary encoder 110 in the protective shell 106, then place the rubber ring 108 between the protective shell 106 and the mounting frame 104, and then insert the rotating shaft of the rotary encoder 110 into the middle slot in the inner cavity of the pitch hinge shaft 105, and then rotate the rotating rod 125 clockwise. A gear 126 will drive the rack 127 to move rightward, and the rack 127 will drive the fixing ring 111 to move along, and the right edge of the fixing ring 111 will push the first wedge block 117, thereby driving the plurality of positioning rods 112 to rotate simultaneously, so that the limit blocks 113 on the plurality of positioning rods 112 rotate into the limit groove 114, and at the same time compress the return spring 116, and after the right edge of the fixing ring 111 moves from the inclined surface of the first wedge block 117 to the horizontal surface of the first wedge block 117, the limit block 113 is stuck in the limit groove 114, so that the protective shell 106 is installed on the front side of the mounting frame 104, and the installation and positioning of the protective shell 106 can be quickly completed only by rotating the rotating rod 125, thereby improving the control of the rotary encoder 11 0 sealing protection efficiency, and at the same time, because the protective shell 106 cooperates with the rubber ring 108 to effectively cover and protect the rotary encoder 110, it is avoided that iron powder, sandstone and other dust are accumulated on the rotary encoder 110 during the material taking process to erode the rotary encoder 110, and affect the detection accuracy of the pitch angle of the rotary encoder 110 on the side-type material taking machine. In addition, because the fixing ring 111 pushes multiple positioning rods 112 at the same time, the limit blocks 113 on the multiple positioning rods 112 are simultaneously inserted into the limit grooves 114, thereby ensuring that the clamping force of the protective shell 106 on multiple positions of the rubber ring 108 is consistent. Compared with the use of bolts to install the protective shell 106, the installation efficiency of the protective shell 106 is greatly improved, and the screw is avoided. The uneven force during the process of turning the knob causes the rubber ring 108 to be damaged and the sealing efficiency to be reduced, thereby improving the sealing protection effect of the rotary encoder 110, thereby ensuring the accuracy of the rotary encoder 110 in detecting the pitch angle of the material reclaimer. When the fixing ring 111 moves to the right, the fixing ring 111 will drive the connecting rod 120 to move with it, and the right end of the connecting rod 120 will push the second wedge block 124, and the second wedge block 124 will drive the rubber pressure block 122 to move toward the middle and stretch the spring at the same time. When the connecting rod 120 moves to the plane of the second wedge block 124, the connecting rod 120 no longer pushes the second wedge block 124, so that the semicircular groove 123 on the rubber pressure block 122 is pressed tightly against the outside of the data line of the rotary encoder 110.This facilitates the installation of the rotary encoder 110 in the protective shell 106 for protection, and at the same time, the data line of the rotary encoder 110 is compressed and sealed, thereby preventing dust from entering the protective shell 106 and corroding the rotary encoder 110 during the material reclaiming process of the reclaimer.

Different from the previous embodiment, this embodiment provides a high-precision pitch side-type material reclaimer with a rotary encoder protection structure, which solves the problem that it is impossible to clean up the dust and debris accumulated above the protective shell 106, resulting in the dust and debris accumulated in the process of removing the protective shell 106 falling into the protective shell 106 and the rotary encoder 110, which increases the trouble of secondary cleaning. The cleaning mechanism 200 includes a gear ring 201 arranged on the outside of the protective shell 106, and the upper end of the rotating rod 125 is fixedly mounted with a second gear 202, the second gear 202 is arranged on one side of the gear ring 201, and the second gear 202 and the gear ring 201 are connected to each other. The toothed ring 201 is meshed with the rubber ring 108, and a scraper 205 is provided on one side of the toothed ring 201 close to the rubber ring 108. The lower end of the scraper 205 is in contact with the upper surface of the protective shell 106, and a recessed groove 206 is provided on one end of the scraper 205 close to the rubber ring 108. The recessed groove 206 is in contact with the surface of the rubber ring 108. A plurality of second sliders 204 are fixedly installed on the inner side of the toothed ring 201, and an annular groove 203 is provided on the outer side of the protective shell 106. The inner diameter of the toothed ring 201 is larger than the outer diameter of the protective shell 106, the size of the second slider 204 is matched with the size of the annular groove 203, and the second slider 204 is slidably connected with the annular groove 203.

[0039] In this embodiment, the scraper strip 205 is fixedly connected to the gear ring 201 by bolts. When the rotary encoder 110 needs to be calibrated, the rotating rod 125 is first rotated counterclockwise, and the first gear 126 under the rotating rod 125 drives the rack 127 to move to the left, and the rack 127 drives the fixed ring 111 to follow the movement. After the first wedge block 117 loses the driving force of the fixed ring 111, the reset spring 116 drives the positioning rod 112 to reset by virtue of the spring resilience, thereby facilitating the removal of the protective shell 106. At the same time, during the counterclockwise rotation of the rotating rod 125, the second gear 202 above the rotating rod 125 drives the gear ring 201 to rotate, and the gear ring 201 rotates along the annular groove 203. At the same time, the gear ring 201 drives the scraper strip 205 to follow the movement, and the scraper strip 205 rotates from one side of the protective shell 106 to the other side of the protective shell 106, so that the scraper strip 205 5 follows the rotation of 160 degrees, and the rotating rod 125 is no longer rotated at this time. During the rotation of the scraper bar 205, the scraper bar 205 will sweep away the dust and debris accumulated on the top of the protective shell 106, and at the same time, the concave groove 206 on the scraper bar 205 will also sweep away the dust and debris remaining on the upper surface of the rubber ring 108, thereby ensuring that no dust and debris will fall into the protective shell 106 and the rotary encoder 110 during the removal of the protective shell 106, thereby facilitating the maintenance and calibration of the rotary encoder 110 and saving the trouble of secondary cleaning by the staff. Through the cooperation of the concave groove 206 on the scraper bar 205, when the scraper bar 205 rotates, the concave groove 206 on the scraper bar 205 will also sweep away the dust and debris remaining on the upper surface of the rubber ring 108, and the second slider 204 cooperates with the annular slide groove 203, thereby ensuring the stability of the rotation of the gear ring 201.

[0040] The rest of the structure is the same as that of Example 1.

[0041] When in use, when the rotary encoder 110 needs to be calibrated, first rotate the rotating rod 125 counterclockwise, the first gear 126 under the rotating rod 125 drives the rack 127 to move left, and the rack 127 drives the fixed ring 111 to follow the movement, and then after the first wedge block 117 loses the driving force of the fixed ring 111, the reset spring 116 drives the positioning rod 112 to reset by virtue of the spring resilience, thereby facilitating the removal of the protective shell 106, and at the same time, during the counterclockwise rotation of the rotating rod 125, the second gear 202 above the rotating rod 125 drives the gear ring 201 to rotate, and the gear ring 201 rotates along the annular groove 203, and at the same time, the gear ring 201 drives the scraper strip 205 to follow As the scraper bar 205 moves, it rotates from one side of the protective shell 106 to the other side of the protective shell 106, so that the scraper bar 205 rotates 160 degrees. At this time, the rotating rod 125 is no longer rotated. During the rotation of the scraper bar 205, the scraper bar 205 will sweep away the dust and debris accumulated on the top of the protective shell 106, thereby ensuring that no dust and debris will fall into the protective shell 106 and the rotary encoder 110 during the removal of the protective shell 106, thereby facilitating the maintenance and calibration of the rotary encoder 110 and saving the trouble of secondary cleaning for the staff, so that the dust and debris accumulated on the top of the protective shell 106 can be scraped off while the protective shell 106 is removed.
