DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are 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.

[0034] Combine the following Figure 1-Figure 10 The invention describes an automatic dust cleaning device for a car tipper.

[0035] like Figure 1-Figure 10 As shown, an automatic dust cleaning device for a car tipper provided by an embodiment of the present invention comprises: a dust cleaning component 1, a support cross bar 2, a folding mechanism 3, a bracket 4 and a transmission mechanism 5. The dust cleaning component 1 is rotatably connected to the support cross bar 2 and the folding mechanism 3 respectively. Since the support cross bar 2 has a supporting function and has fewer supporting points than the overall device, the material used for the support cross bar 2 needs to have the characteristics of high strength and light weight. Therefore, aluminum alloy materials can be used, which have the characteristics of low density, high strength, and good corrosion resistance. The folding mechanism 3 is detachably connected to the support cross bar 2. The main function of the folding mechanism 3 is to eject or retract the dust cleaning component 1 when dust cleaning is required or after dust cleaning is completed. This can not only improve the dust cleaning efficiency, but also prevent the automatic dust cleaning device from interfering with the operation of the car tipper. The support cross bar 2 is slidably connected to the bracket 4, so that the support cross bar 2 can move up and down in the bracket 4, so that the dust cleaning component 1 can wipe back and forth on the surface of the photoelectric signal board of the car tipper. As a component supporting the entire device, the weight and fixing method of the bracket 4 need special attention. Carbon steel can usually be used to improve the weight. In addition, carbon steel has the characteristics of high strength, easy processing, strong adaptability, etc. As a bracket, it performs well in terms of strength, cost-effectiveness, processing convenience and adaptability. The transmission mechanism 5 is detachably connected to the bracket 4.

[0036] The transmission mechanism 5 is related to the drive and transmission of the entire device and needs to have a high transmission efficiency. The transmission mechanism 5 includes an intermittent transmission group 50, a direction-changing drive group 51 and a reciprocating gear group 52. The intermittent transmission group 50 can transmit the driving force in the same time to achieve the purpose of intermittent transmission. The main function of the direction-changing drive group 51 is to convert the driving force in one direction into the driving force in the relatively vertical direction. At the same time, it also has a self-locking function so that the force will not be transmitted in the reverse direction to increase the stability of the device. The function of the reciprocating gear group 52 is to enable the components other than the bracket to slide along the bracket and enable it to move back and forth in the bracket, so that the dust cleaning component 1 can be wiped back and forth. The intermittent transmission group 50 is detachably connected to the folding mechanism 3. The intermittent transmission component 50 drives the folding mechanism 3 to move, and the movement time interval between the two is determined by the intermittent transmission component 50. The intermittent transmission group 50 is detachably connected to the direction-changing drive group 51. The reciprocating gear group 52 is detachably connected to the direction-changing drive group 51. The linkage between the intermittent transmission group 50 and the reversing drive group 51 enables the intermittent transmission component 50 to be normally recovered after the reciprocating gear group 52 makes a round of reciprocating motion, and the recovery time interval can be set by the intermittent transmission group 50 to the reciprocating time of the reciprocating gear group 52.

[0037] The cleaning assembly 1 includes a cleaning plate 10, a fixed plate 11 and an elastic sheet 12. The cleaning plate 10 is usually composed of a polypropylene plastic base plate and bristles made of PVC wire. The polypropylene base plate has high tensile strength and surface hardness, and its crystallinity is high and the structure is regular, so it has excellent mechanical properties. The bristles made of PVC wire have the characteristics of acid resistance, alkali resistance, corrosion resistance, antistatic, etc., and can absorb very small particles. The top of the bristles is fluffy, and the rigidity and softness are moderate, which can effectively prevent the bristles from damaging the photoelectric signal board, thereby improving the service life of the photoelectric signal board. The fixed plate 11 is rotatably connected to the support cross bar 2 to support the rotation of the fixed plate 11. The elastic sheet 12 is detachably connected to the fixed plate 11. The elastic sheet 12 is in contact with the cleaning plate 10, and one side of the cleaning plate is treated with arc and fillet. When the cleaning assembly 1 is retracted, the treated cleaning plate 10 contacts the support cross bar 2, which will cause the cleaning plate 10 to be squeezed and then shrink into the fixed plate 11. When the dust cleaning plate 10 shrinks to be level with the side of the receiving groove opened on the supporting cross bar 2, it will be tightly attached to the receiving groove under the action of the elastic sheet 12, which facilitates the subsequent self-cleaning. The elastic sheet 12 is usually a beryllium copper plate with a certain curvature at the beginning. The elastic sheet 12 made of beryllium copper has high strength, high hardness, good elastic limit and fatigue resistance. These characteristics enable beryllium copper to maintain its shape and function when subjected to repeated stress. This allows the elastic sheet 12 itself to maintain its good elasticity when used for a long time.

[0038] The fixed plate 11 includes a plate body 110, two limit blocks 111 and a limit column 112. The fixed plate 11 is generally made of aluminum alloy as a whole, which has the characteristics of high hardness and high strength as well as low density. The load on the supporting cross bar 2 is reduced, and the service life of the supporting cross bar 2 is increased. The two limit blocks 111 are fixedly connected to the plate body 110, and are mainly used to limit the elastic sheet 12 so that the elastic sheet 12 can work on a set stroke. The limit column 112 is fixedly connected to the plate body 110. The limit column 112 can prevent the elastic sheet 12 from shifting during use, and is also used to fix the cleaning plate 10. The cleaning plate 10 is screwed to the limit column 112. It is convenient for the later maintenance and replacement of the cleaning plate 10.

[0039] The support cross bar 2 includes a support body 20 and a dust collecting bin 21. The support body 20 is used to support all mechanisms and components except the bracket 4. The dust collecting bin 21 is used to remove the carbon powder or coal powder on the cleaning plate 10 to maintain the cleanliness of the cleaning plate 10 and extend the service life of the cleaning plate 10. The dust collecting bin 21 is fixedly connected to the support body 20. The receiving groove on the support body 20 is connected to the dust collecting bin 21 and is connected to the external dust collector. The carbon powder or coal powder on the cleaning plate 10 can directly enter the external dust collector through the dust collecting bin 21 for centralized treatment. The bracket 4 includes a reciprocating bin 40, a rack 41 and a sealing plate 42. The rack 41 is a double-sided rack, that is, gear teeth with the same pitch are provided on both sides, so as to serve as the reciprocating route of the reciprocating gear set 52. The sealing plate 42 is detachably connected to the reciprocating bin 40. It is used to encapsulate the reciprocating bin 40 and to prevent the reciprocating gear set 52 from exceeding the stroke and malfunctioning. The rack 41 is fixedly connected to the reciprocating chamber 40. The support body 20 is slidably connected to the reciprocating chamber 40. A slide groove matching the support body 20 is provided in the reciprocating chamber 40. The slide groove not only limits the support body 20, but also prevents the support body 20 from being unstable when moving up and down, thereby further improving the service life of the device.

[0040] The folding mechanism 3 includes a control rod 30, a rotating member 31 and a rotating gear set 32. The material used for the control rod 30 and the rotating member 31 is generally stainless steel, which has high hardness and high tensile strength. One end of the control rod 30 is rotatably connected to the fixed plate 11, and the other end is rotatably connected to the rotating member 31. The control points at both ends of the control rod 30 are arranged on different horizontal lines, so that the dust cleaning component 1 can fit perfectly with the receiving slot after recovery. The rotating member 31 is fixedly connected to the rotating gear set 32. When the rotating member 31 rotates in one direction, it will drive the control rod 30 at one end thereof to move along with the end of the rotating member 31, thereby pulling the other end of the control rod 30 to move. Through the principle of the lever, the dust cleaning component 1 will be pulled or pushed by the control rod 30, and rotate around the connection point between the dust cleaning component 1 and the supporting cross bar 2 until the dust cleaning component 1 is recovered into the receiving slot or popped out of the receiving slot.

[0041] The rotating gear set 32 ​​includes a rotating gear 320, a sector gear 321 and a driving disc 322. The driving disc 322 is cylindrical, and a cylindrical push block is fixedly installed at a non-center position on one side of the surface of the driving disc 322 to push the sector gear 321 to do a reciprocating motion. The sector gear 321 is composed of a sector gear with a 90° angle and a sliding rod. The rotating gear 320 is fixedly connected to the rotating member 31 through a transmission rod, and the transmission rod is rotationally connected to the support cross bar 2. The rotating gear 320 drives the rotating member 31 to rotate. The sector gear 321 is meshed with the rotating gear 320 and is rotationally connected to the support cross bar 2. The sector gear 321 drives the rotating gear 320 to rotate while rotating. The angular velocity of the two gears can be adjusted by replacing gears of different radius sizes. The driving disc 322 is slidably connected to the sector gear 321 and is rotationally connected to the support cross bar 2. Because the cylindrical push block is fixed at a non-center position on the surface of the driving disk 322, the driving disk 322 can make the push block move eccentrically when rotating, and at the same time drive the sector gear 321 to move back and forth, further making the rotating member 31 move back and forth left and right.

[0042] The intermittent transmission group 50 includes a groove wheel 500, two chain discs 501, a chain 502 and a toggle block 503. A groove wheel mechanism is provided between the groove wheel 500 and the toggle block 503. The groove wheel mechanism usually includes a dial and a groove wheel, the dial is provided with a round pin, and the groove wheel is provided with a radial groove. When the dial rotates continuously, through the effect of the locking arc, the groove wheel will be stationary before the dial round pin enters the radial groove, and will move after entering. This mechanism can transform continuous rotation into intermittent rotation, and has the characteristics of simple structure, easy manufacturing and reliable operation. In this device, a chain and a toggle block 503 are used to replace the dial, so that it can perform long-distance intermittent transmission. The two chain discs 501 are respectively meshed with the chain 502 and the chain is driven. There is no specific size restriction on the diameter size of the two chain discs 501, and the intermittent duration of the intermittent transmission can also be changed by changing the size of the two chain discs 501. The toggle block 503 is fixedly connected to the chain 502, and the toggle block 503 is slidably connected to the groove wheel 500. The chain 502 rotates to drive the toggle block 503 to move with the chain, and when the remaining groove wheels 500 are in contact, the fluctuation groove wheel 500 will rotate, thereby driving the driving disk 322 to rotate.

[0043] An automatic dust cleaning device for a dumper also includes a motor 6. The motor 6 is detachably connected to the reversing drive group 51. The reversing drive group 51 includes a driving gear 510, a driven gear 511, a worm 512 and a worm wheel 513. The material used for all the gears in the reversing drive group 51 is usually carbon structural steel (such as 45 steel, Q235, etc.), which has high strength and good toughness, and its mechanical properties can be improved by heat treatment. Among them, high carbon steel has the best high hardness and wear resistance. Therefore, when selecting materials, it can be adapted according to needs. The driving gear 510 is meshed with the driven gear 511. The rotation of the driving gear 510 drives the driven gear 511 to rotate, and further drives the chain plate 501 to rotate, thereby driving the intermittent transmission group 50 to work. The worm 512 is fixedly connected to the driving gear 510 and is rotationally connected to the supporting cross bar 2. The rotation of the driving gear 510 drives the worm 512 to rotate, thereby providing power for the reciprocating gear group 52. The worm wheel 513 meshes with the worm 512 and is rotationally connected to the support crossbar 2. A gear-worm structure is provided between the worm 512 and the worm wheel 513. The gear-worm structure is a mechanical device for transmitting motion and power between staggered axes. The characteristics include being able to achieve a large transmission ratio, operating smoothly and with low noise, having a compact structure, and having a self-locking function.

[0044] The reciprocating gear set 52 includes a transmission gear 520, two directional gears 521 and two half gears 522. The transmission gear 520 is coaxially arranged and fixedly connected with the worm gear 513. The worm gear 513 rotates and serves as a power source for the transmission gear 520. The transmission gear 520 meshes with the two directional gears 521. The rotation of the transmission gear 520 simultaneously drives the two directional gears 521 to rotate, and the rotation directions of the two directional gears 521 at this time are opposite. The two half gears 522 are fixedly connected to the two directional gears 521 respectively. When the two directional gears 521 rotate, the two half gears 522 are driven to rotate at the same time. The two half gears 522 face the same direction. When rotating, the two half gears 522 will alternately mesh with the rack 41. Because the rotation directions of the two directional gears 521 are opposite, the rotation directions of the two half gears 522 are also opposite, so that the reciprocating gear set 52 can do reciprocating motion in the bracket 4.

[0045] The working principle of the present invention is as follows: Figure 1-Figure 10As shown, when working, the external vacuum cleaner is connected to the dust collection bin 21. The operator remotely controls to turn on the power supply, so that the motor 6 works, drives the driving gear 510 to rotate, and further drives the worm 512 to rotate, so that the reciprocating gear set 52 located at the lowest position of the bracket 4 moves upward. At the same time, the rotation of the driving gear 510 drives the driven gear 511 to rotate, and further drives the chain plate 501 connected to the driven gear 511 to rotate, thereby driving the chain 502 to rotate. Because the toggle block 503 is fixed on the chain 502, the chain 502 rotates and drives the toggle block 503 to move along the chain. When the toggle block reaches the axial groove on the groove wheel 500, it drives the groove wheel 500 to rotate, thereby driving the driving disk 322 to rotate. Because the surface of the driving disk 322 is fixed with an eccentric cylindrical push block, the cylindrical push block will make an eccentric movement while the driving disk 322 rotates, thereby making the fan-shaped gear 321 reciprocate under the influence of the cylindrical push block, further making the rotating gear 320 reciprocate, and because the movement of the cylindrical push block is periodic, the movement of the rotating gear 320 also has the same period. The rotating gear 320 drives the rotating member 31 to reciprocate, that is, swing left and right, so that the control rod 30 can push and pull under the action of the rotating member 31, thereby making the cleaning component 1 pop out or retract on the basis of the lever. When the cleaning component 1 pops out, the cleaning plate 10 will pop out under the action of the elastic sheet 12 and remain in a certain position based on the limiting column 112. At the same time, due to the movement of the reciprocating gear set 52, the device can move up and down to clean the photoelectric signal board. When the cleaning component 1 returns and moves to the bottom, the cleaning component 1 will be retracted inward. Due to the rounded corners on the surface of the cleaning plate 10, the cleaning plate 10 will be squeezed inward by the supporting cross bar 2, and the cleaning plate 10 can return to its original position. When the cleaning component 1 is retracted into the receiving groove in the supporting cross bar 2, the externally connected vacuum cleaner will remove the carbon ash or coal ash on the cleaning plate 10, thereby ensuring the cleanliness of the next use and increasing the service life of the device.
