Description

Technical Field

[0001] This invention relates to the technical field of conveying raw materials for concrete preparation, and in particular to a raw material conveying device for preparing expanded perlite concrete. Background Technology

[0002] Expanded perlite concrete is a lightweight insulating concrete that uses lightweight expanded perlite as aggregate. It combines the low density and low thermal conductivity of expanded perlite with the bonding properties of cementitious materials, and is widely used in building insulation, heat insulation and non-load-bearing structures.

[0003] Intelligent overhead conveyor systems, with their advantages of efficient space utilization, automated and precise control, and flexible path scheduling, demonstrate unique strengths in the preparation of expanded perlite concrete (including ready-mixed concrete production, precast component manufacturing, and on-site pouring assistance). They are particularly suitable for scenarios such as precise raw material delivery, short-distance transfer after mixing, and automated circulation of precast components, effectively solving problems such as large space occupation, dust pollution, high dependence on manual labor, and low transfer efficiency of traditional conveying methods (such as belt conveyors, bucket elevators, and forklifts).

[0004] Chinese patent CN120962861A discloses a dust-proof conveying device for processing concrete mortar raw materials. The conveying spiral blade shaft is located within the inner cavity of the conveying box. The loading mechanism includes a vertical cylinder with its top end sleeved on the bottom front end of the conveying box, a cover at the bottom end of the vertical cylinder, and a loading spiral blade shaft within the vertical cylinder and the cover. A power assembly drives the loading spiral blade shaft to rotate synchronously. The unloading mechanism includes a square shell at the rear end of the conveying box and a telescopic cylinder at the bottom end of the square shell. The negative pressure pipe includes a main pipe and an input bend connecting the main pipe and the conveying box. The dust removal unit includes a cabinet filled with clean water, an axial flow fan connected to the top of the cabinet, and a filter element within the cabinet. The filter element includes a rotatable cylindrical filter screen, and the rear wall of the cabinet has an air outlet corresponding to the cylindrical filter screen. A corrugated pipe connects the axial flow fan and the main pipe. A traveling frame is mounted at the bottom of the conveying box to improve the dust-proof effect during the conveying of concrete mortar raw materials.

[0005] The existing technology and the above-mentioned related technologies have the following drawbacks: Concrete raw materials contain a variety of materials. In the transportation of concrete raw materials, generally only one type of concrete material is transported to the configuration device. However, after the conveyor belt feeding device has completed the feeding of one configuration device, it is inconvenient to feed other configuration materials. The feeding can only be done one type at a time, and the raw materials added to the configuration device are prone to stratification and are not easy to mix together. Summary of the Invention

[0006] In order to enable simultaneous feeding of multiple raw materials in multiple configuration devices, the present invention provides a raw material conveying device for the preparation of expanded perlite concrete.

[0012] It also includes a mixing and feeding mechanism, which is installed at the lower end of the linkage dual-shaft drive assembly. The lower end of the material distribution and storage mechanism is connected to the upper end of the mixing and feeding mechanism. The linkage dual-shaft drive assembly drives the mixing and feeding mechanism and the material distribution and storage mechanism to rotate relative to the material inlet control assembly. Different materials are added to different material distribution and storage mechanisms through the material inlet control assembly. The materials in the material distribution and storage mechanisms enter the mixing and feeding mechanism. The mixing and feeding mechanism first premixes the materials inside and then discharges them from its lower end.

[0013] Optionally, the track suspension drive mechanism includes:

[0014] A suspension track frame, wherein a track groove is provided at the lower end of the suspension track frame.

[0015] The inner support block has two parts. The upper end of the inner support block is located inside the track groove on the lower side of the suspension track frame. A horizontally arranged support wheel is rotatably installed on one end of the inner support block inside the track groove.

[0016] The drive wheels are vertically located on both sides of the suspension track frame and are connected to the inner support blocks.

[0028] A baffle plate is provided, and multiple baffle plates are fixedly inserted into the lower end of the single material feeding cylinder. The baffle plate has an eccentric feeding hole that runs through the upper and lower parts.

[0029] The drive shaft is coaxially disposed inside the single material feeding cylinder. The baffle plate is rotatably sleeved on the outer surface of the drive shaft. The central drive shaft is located inside the mixing feeding cylinder and has an external gear ring coaxially mounted at one end. A spur gear is mounted at the lower end of the drive shaft and meshes with the outer ring surface of the external gear ring.

[0030] It also includes a blocking disc, the number of which is the same as the number of baffle discs. The blocking discs are arranged in a one-to-one correspondence with the bottom surface of the baffle disc. The blocking discs are coaxially fixedly sleeved on the outer surface of the transmission shaft. The blocking discs have a through-hole that runs vertically through the shaft. During the transmission of the blocking discs along the transmission shaft, the through-hole connects with the lower end of the adjacent upper eccentric discharge hole.

[0031] Optionally, a fixed shaft is coaxially rotatably inserted into the lower end of the central drive shaft, and the lower end of the fixed shaft is fixed to the inner wall of the mixing feed cylinder.

One end of the horizontal shaft is coaxially mounted with an end bevel gear inside the central drive shaft. The fixed shaft is mounted with arc-shaped bevel gear rings on both the upper and lower sides of the end bevel gear. The two arc-shaped bevel gear rings are circumferentially offset in the direction of the fixed shaft axis.

[0035] It also includes a multi-section elastic telescopic mixing rack, of which multiple sections are provided. The upper end of the multi-section elastic telescopic mixing rack is rotatably inserted into the bottom surface of the hollow rod.

The driving bevel gear is coaxially installed on the outer surface of the horizontal shaft. The two driving bevel gears meshed by two adjacent driven bevel gears are arranged on different sides.

[0036] Optionally, the layered component includes:

[0037] An internally threaded collar is fixedly installed inside the mixing feed cylinder.

[0041] The movable material tray is provided with a paddle ring frame on the lower side. The inner ring surface of the paddle ring frame has multiple rod-shaped structures. The paddle ring frame is elastically slidably inserted into the inside of the mixing feed cylinder.

[0042] Optionally, the material inlet control assembly includes a disc and a dispensing cylinder. The lower end of the dispensing cylinder is installed through the upper surface of the disc. The disc is fixedly sleeved on the outside of the drive sleeve shaft. The bottom surface of the disc contacts the upper end of the single material dispensing cylinder. The lower end of the dispensing cylinder and the single material dispensing cylinder are equidistant from the axis of the drive sleeve shaft.

[0043] In summary, the present invention has the following beneficial technical effects:

[0044] 1. This invention uses a track suspension drive mechanism to drive a linkage dual-axis drive assembly to move, which in turn moves the feed inlet of the feed inlet control assembly to the addition position of different raw materials. The feed inlet control assembly sequentially adds different raw materials to different material distribution and storage mechanisms. After all raw materials have been added, the track suspension drive mechanism then drives the overall mixing and feeding mechanism to the discharge position. The raw materials in different material distribution and storage mechanisms are simultaneously added to the overall mixing and feeding mechanism for pre-mixing before being discharged. This invention can add materials to different configuration devices, and all added materials are pre-mixed.

[0045] 2. This invention uses a combination of multiple baffles and blocking discs. The blocking discs block the eccentric discharge holes on the upper side, first blocking the single raw material added to the single material discharge cylinder. Before moving the discharge position, no material will fall. After moving to the discharge position, the rotating blocking discs cause the round holes to intermittently connect with the eccentric discharge holes. Since the lower ends of the adjacent eccentric discharge holes are located on both sides of the axis of the baffles, the raw materials in the single material discharge cylinder gradually fall off in layers.

[0046] 3. This invention utilizes the combined use of an internal threaded collar, a movable material support plate, and a multi-section elastic telescopic mixing frame. The movable material support plate supports the falling raw materials, and the central drive shaft drives the multi-section elastic telescopic mixing frame to rotate forward and backward around the central drive shaft via a hollow rod. Furthermore, through the meshing transmission of the active and driven bevel gears, the multi-section elastic telescopic mixing frame rotates around its own axis, stirring the raw materials on the upper side of the movable material support plate for mixing. During mixing, the raw materials gradually fall downward to the upper side of the mixing push plate of the next layer, increasing the material residence time and thus increasing the mixing time.

[0047] 4. This invention utilizes the combined use of a feeding ring and a blocking plate. Before the feeding ring contacts the blocking plate, the blocking plate, in an elastic connection with the movable material tray, seals the lower end of the mixing discharge hole. The multi-section elastic telescopic mixing frame stirs the raw materials on the upper side of the movable material tray. After the rod-shaped structure of the feeding ring contacts and blocks the blocking plate, the blocking plate separates from the mixing discharge hole, causing the mixed raw materials on the upper side to fall off, further increasing the mixing time of the raw materials.

[0058] The following is in conjunction with the appendix Figures 1-9 The present invention will be described in further detail below.

[0059] This invention discloses a raw material conveying device for the preparation of expanded perlite concrete. For example... Figure 1As shown, it includes a track suspension drive mechanism 1, a linkage dual-axis drive assembly 2, a material inlet control assembly 3, a material distribution and storage mechanism 4, and a mixed integral feeding mechanism 5.

[0060] The upper end of the linkage dual-axis drive assembly 2 is connected to the track suspension drive mechanism 1. The track suspension drive mechanism 1 drives the linkage dual-axis drive assembly 2 to move along the track and controls the position of the linkage dual-axis drive assembly 2.

[0061] The feed inlet control component 3 is connected to the linkage dual-axis drive component 2, and the linkage dual-axis drive component 2 controls the feed inlet control component 3 to rotate relative to the track suspension drive mechanism 1.

[0062] Multiple material distribution and storage mechanisms 4 are provided. The material distribution and storage mechanisms 4 are located below the material inlet control component 3. The material distribution and storage mechanisms 4 are connected to the linkage dual-axis drive component 2. The number of material distribution and storage mechanisms 4 is set to match the amount of raw materials that need to be used. The linkage dual-axis drive component 2 can control the position of the inlet of the material inlet control component 3.

[0063] In this embodiment, the upper side of the material inlet control component 3 is set as the inlet. After the material inlet control component 3 moves to the lower side of the raw material storage device, the raw material storage device can add the corresponding raw material into the material inlet control component 3 through the inlet. The linkage dual-axis drive component 2 controls the material distribution and storage mechanism 4 to change the position relative to the material inlet control component 3. When moving to the lower side of different raw material storage devices, different material distribution and storage mechanisms 4 move to communicate with the corresponding material inlet control component 3, so that the raw material falls into the inner side of the material distribution and storage mechanism 4 through the material inlet control component 3.

[0064] The integrated feeding mechanism 5 is installed at the lower end of the linkage dual-shaft drive assembly 2. The lower end of the material distribution and storage mechanism 4 is connected to the upper end of the integrated feeding mechanism 5. The linkage dual-shaft drive assembly 2 drives the integrated feeding mechanism 5 and the material distribution and storage mechanism 4 to rotate relative to the material inlet control assembly 3. Different materials are added to different material distribution and storage mechanisms 4 through the material inlet control assembly 3. The materials in the material distribution and storage mechanism 4 enter the interior of the integrated feeding mechanism 5. The integrated feeding mechanism 5 first premixes the materials inside and then discharges them from its lower end.

[0065] In this embodiment, a primary detection and control component is installed on the outside of the material inlet control component 3. When the primary detection and control component detects that the raw material storage device has moved to one side of the linkage dual-axis drive component 2, it controls the upper side of the material inlet control component 3 to move to communicate with the raw material storage device, and at the same time controls the corresponding material distribution and storage mechanism 4 to move to communicate with the material inlet control component 3.

[0066] A secondary detection and control component is installed on the outside of the mixing and feeding mechanism 5. When the mixing and feeding mechanism 5 is detected to have moved to the position of the configuration device, the raw materials in the material storage mechanism 4 are controlled to fall into the mixing and feeding mechanism 5 for mixing before being discharged, thereby increasing the intelligent working effect of the overall equipment.

[0067] like Figure 2 As shown, in this embodiment, the track suspension drive mechanism 1 includes a suspension track frame 11, an inner support block 12, a drive wheel 14, and a rotating support plate 15.

[0068] The lower end of the suspension track frame 11 is provided with a track groove. The suspension track frame 11 is composed of multiple detachable parts. There are two inner support blocks 12. The upper end of the inner support block 12 is located inside the track groove on the lower side of the suspension track frame 11. A horizontally arranged support wheel 13 is rotatably installed on one end of the inner support block 12 located inside the track groove. The support wheel 13 supports the movement of the inner support block 12 in the track groove, reducing the wear of the inner support block 12 when it moves.

[0069] The drive wheel 14 is vertically located on both sides of the suspension track frame 11. The drive wheel 14 is connected to the inner support block 12. The number of rotating support plates 15 is the same as the number of inner support blocks 12. The two rotating support plates 15 are rotatably installed at the lower ends of the two inner support blocks 12 in a one-to-one correspondence. The upper end of the linkage dual-axis drive assembly 2 is rotatably installed between the two rotating support plates 15.

[0070] In this embodiment, the drive wheel 14 is equipped with a motor. When the drive wheel 14 rotates, it contacts the suspension track frame 11 and pushes the inner support block 12 to move relative to the suspension track frame 11. When the suspension track frame 11 has a bent part, the two rotating support plates 15 move closer to each other and rotate relative to the linkage dual-axis drive assembly 2, so that the two inner support blocks 12 can turn inside the suspension track frame 11.

[0071] like Figure 3 and Figure 4 As shown, in this embodiment, the linkage dual-axis drive assembly 2 includes a drive sleeve shaft 21 and a drive inner shaft 22.

[0072] The drive sleeve shaft 21 is rotatably connected to one end of the two rotating support plates 15. The drive sleeve shaft 21 drives itself relative to one of the two rotating support plates 15, and the other rotating support plate 15 can rotate relative to the drive sleeve shaft 21. The feed port control component 3 is connected to the drive sleeve shaft 21.

[0073] In this embodiment, a motor that applies power to the drive sleeve shaft 21 is installed on the upper side of the rotating support plate 15 located on the upper side.

[0074] The inner drive shaft 22 is coaxially mounted at the lower end of the drive sleeve shaft 21. The inner drive shaft 22 can drive itself to rotate relative to the drive sleeve shaft 21. A motor that applies power to the inner drive shaft 22 is mounted on the outside of the drive sleeve shaft 21. The material distribution and storage mechanism 4 and the overall mixing and unloading mechanism 5 both rotate with the inner drive shaft 22.

[0075] The integrated feeding mechanism 5 includes a mixing feeding cylinder 51, a central drive shaft 52, a mixing component 53, and a layering component 54.

[0076] The mixing feed cylinder 51 is installed at the lower end of the drive inner shaft 22, and the lower end of the material distribution and storage mechanism 4 is installed on the upper surface of the mixing feed cylinder 51. The drive inner shaft 22 can drive the material distribution and storage mechanism 4 to rotate and change the position of the drive inner shaft 22. The central drive shaft 52 is installed through the axis of the mixing feed cylinder 51, and the mixing feed cylinder 51 is equipped with a motor that applies power to the drive inner shaft 22.

[0077] Multiple mixing components 53 are provided. The mixing components 53 are connected to the central drive shaft 52. The central drive shaft 52 drives the mixing components 53 to reciprocate in the mixing feed cylinder 51. The moving mixing components 53 can mix and process the materials in the mixing feed cylinder 51.

[0078] The number of layering components 54 is the same as that of mixing components 53. The layering components 54 are located below the mixing components 53. The material on the upper side of the layering components 54 can fall to the lower side. The layering components 54 slow down the falling time of the mixed material and increase the mixing effect of the material.

[0079] The material distribution and storage mechanism 4 includes a single material feeding cylinder 41, a baffle plate 42, a drive shaft 43, and a blocking plate 46.

[0080] The material inlet control assembly 3 includes a disc 31 and a material distribution cylinder 32. The lower end of the material distribution cylinder 32 is installed through the upper surface of the disc 31. The disc 31 is fixedly sleeved on the outside of the drive sleeve shaft 21. The bottom surface of the disc 31 contacts the upper end of the single material feeding cylinder 41. The lower end of the material distribution cylinder 32 and the single material feeding cylinder 41 are equidistant from the axis of the drive sleeve shaft 21.

[0081] The single material feeding cylinder 41 is fixed to the drive inner shaft 22. The lower end of the single material feeding cylinder 41 is installed on the upper end of the mixing feeding cylinder 51. The material in the single material feeding cylinder 41 can fall into the mixing feeding cylinder 51. The diameter of the upper end of the single material feeding cylinder 41 is smaller than the diameter of the lower end of the distributing cylinder 32.

[0082] When the upper end of the single material feeding cylinder 41 is completely misaligned with the upper end of the distributing cylinder 32, the disc 31 can block the upper end of the single material feeding cylinder 41, effectively preventing material dust from leaking during transfer and reducing dust pollution.

[0083] Multiple baffles 42 are provided. The baffles 42 are fixedly inserted into the lower end of the single material feeding cylinder 41. The baffles 42 have eccentric feeding holes 48 that run through the upper and lower parts.

[0084] The drive shaft 43 is coaxially arranged inside the single material feeding cylinder 41. The baffle plate 42 is rotatably sleeved on the outer surface of the drive shaft 43. The central drive shaft 52 is located inside the mixing feeding cylinder 51 and has an external gear ring 44 coaxially installed at one end. The lower end of the drive shaft 43 is equipped with a spur gear 45, which meshes with the outer ring surface of the external gear ring 44. When the central drive shaft 52 rotates, it can drive the drive shaft 43 to rotate through the meshing of the external gear ring 44 and the spur gear 45.

[0085] The number of blocking discs 46 is the same as the number of baffle discs 42. The blocking discs 46 are arranged in a one-to-one correspondence with the bottom surface of the baffle disc 42. The blocking discs 46 are coaxially fixedly sleeved on the outer surface of the drive shaft 43. The blocking discs 46 have a through-hole 47. When the blocking discs 46 follow the drive shaft 43, the through-hole 47 is connected to the lower end of the eccentric feeding hole 48 on the adjacent upper side.

[0086] The drive shaft 43 drives the blocking disc 46 to rotate. As the blocking disc 46 rotates, it causes the round hole 47 to intermittently connect with the lower end of the eccentric feeding hole 48. The material on the upper side falls downward through the eccentric feeding hole 48 and the round hole 47.

[0087] The lower end of the eccentric feeding hole 48 is eccentrically set with the baffle plate 42. The opening at the upper end of the eccentric feeding hole 48 is larger than the opening at the lower end. The inner diameter of the upper end of the eccentric feeding hole 48 is adapted to the upper end of the baffle plate 42, reducing the residue at the lower end of the eccentric feeding hole 48. When the blocking plate 46 rotates with the drive shaft 43, the circular hole 47 can be coaxially connected with the lower end of the adjacent upper eccentric feeding hole 48. The lower ends of the two eccentric feeding holes 48 corresponding to the two adjacent baffle plates 42 are located on both sides of the axis of the baffle plate 42, so that the upper and lower eccentric feeding holes 48 can alternately connect with the corresponding circular hole 47, so that the material falls downward alternately.

[0088] like Figures 5-9 As shown, in this embodiment, a fixed shaft 55 is coaxially rotatably inserted into the lower end of the central drive shaft 52. The lower end of the fixed shaft 55 is fixed to the inner wall of the mixing feed cylinder 51. The rotation of the central drive shaft 52 causes it to rotate relative to the fixed shaft 55.

[0089] The mixing assembly 53 includes a hollow rod 531, a horizontal shaft 532, and a multi-section elastic telescopic mixing frame 535. The hollow rod 531 is vertically mounted on the circumferential surface of the central drive shaft 52.

[0090] The horizontal shaft 532 is rotatably inserted into the inner side of the hollow rod 531. The horizontal shaft 532 rotates through the outer surface of the central drive shaft 52. One end of the horizontal shaft 532 is coaxially mounted with an end bevel gear 533 inside the central drive shaft 52. The fixed shaft 55 is equipped with arc-shaped bevel gear rings 534 on both the upper and lower sides of the end bevel gear 533. The two arc-shaped bevel gear rings 534 are circumferentially offset in the direction of the axis of the fixed shaft 55. As the horizontal shaft 532 rotates with the central drive shaft 52, the end bevel gear 533 alternately meshes with the arc-shaped bevel gear rings 534 set on the upper and lower sides. The end bevel gear 533 drives the horizontal shaft 532 to rotate in both directions by meshing with the two arc-shaped bevel gear rings 534.

[0091] Multiple multi-section elastic telescopic mixing racks 535 are provided. The upper end of the multi-section elastic telescopic mixing rack 535 is rotatably inserted into the bottom surface of the hollow rod 531. One end of the multi-section elastic telescopic mixing rack 535 located inside the hollow rod 531 is coaxially mounted with a driven bevel gear 537. A driving bevel gear 536 meshes with one side of the driven bevel gear 537. The driving bevel gear 536 is coaxially mounted on the outer surface of the horizontal shaft 532. The two driving bevel gears 536 meshed by two adjacent driven bevel gears 537 are arranged on different sides.

[0092] The multi-section elastic telescopic mixing rack 535 can extend and retract in multiple stages. When the horizontal shaft 532 rotates, the multi-section elastic telescopic mixing rack 535 is driven to rotate through the meshing of the active bevel gear 536 and the driven bevel gear 537. The two adjacent active bevel gears 536 are located on different sides of the two adjacent driven bevel gears 537, so that the two adjacent multi-section elastic telescopic mixing racks 535 rotate in opposite directions, increasing the counter-stirring effect of material mixing.

[0093] The layered assembly 54 includes an internally threaded collar 541 and a movable material tray 542.

[0094] An internally threaded collar 541 is fixedly installed inside the mixing feed cylinder 51. A movable material support plate 542 is slidably sleeved on the outside of the central drive shaft 52. The mating part between the central drive shaft 52 and the movable material support plate 542 is non-circular. While the central drive shaft 52 can drive the movable material support plate 542 to rotate, the movable material support plate 542 can slide up and down on the outside of the central drive shaft 52. The outer ring surface of the movable material support plate 542 is threaded into the outside of the internally threaded collar 541. The movable material support plate 542 is open... The mixing and feeding hole 543 is provided, and the multi-section elastic telescopic mixing frame 535 is located at the lower end of the mixing and feeding hole 543. During the forward and reverse rotation of the driving inner shaft rod 22, the movable material support plate 542 moves up and down by engaging with the inner threaded collar 541. The frequency of the forward and reverse rotation of the driving inner shaft rod 22 is sufficient to prevent the movable material support plate 542 from disengaging from the inner threaded collar 541 and from moving to the uppermost side of the inner threaded collar 541 and causing jamming.

[0095] The lower end of the mixing discharge hole 543 is eccentrically set with the movable material support plate 542. The upper opening of the mixing discharge hole 543 is larger than its lower opening. A blocking plate 544 that can be elastically twisted is installed at the bottom axis of the movable material support plate 542. The blocking plate 544 can block the lower end of the adjacent upper mixing discharge hole 543.

[0096] A paddle ring frame 545 is provided on the lower side of the movable material tray 542. The inner ring surface of the paddle ring frame 545 has multiple rod-shaped structures. The paddle ring frame 545 is elastically slidably inserted into the inside of the mixing feed cylinder 51.

[0097] In this embodiment, when the rod-shaped structure of the deflector ring 545 is not in contact with the blocking plate 544, the blocking plate 544, in its elastic connection with the movable material tray 542, blocks the lower end of the mixing discharge hole 543, preventing the material from falling downwards. At this time, the multi-section elastic telescopic mixing frame 535 can fully agitate the material on the upper side of the movable material tray 542. Simultaneously, as the movable material tray 542 moves up and down, the multi-section elastic telescopic mixing frame 535 can extend and retract synchronously.

[0098] When the movable material tray 542 moves downward, causing the blocking plate 544 to collide with the rod-shaped structure inside the paddle ring frame 545, the blocking plate 544 separates from the mixing discharge hole 543 under the obstruction of the rod-shaped structure of the paddle ring frame 545, so that the material on the upper side of the movable material tray 542 can fall through the lower end of the mixing discharge hole 543.

[0099] The working principle is as follows: The track suspension drive mechanism 1 drives the linkage dual-axis drive component 2 to move, which in turn moves the feed port of the feed port control component 3 to the addition position of different raw materials. The linkage dual-axis drive component 2 drives the feed port control component 3 to align with the upper feeding device. When it moves to the feeding port position of different raw materials, the linkage dual-axis drive component 2 drives different material distribution and storage mechanisms 4 to move to the lower side of the feed port control component 3. The feed port control component 3 adds different raw materials to the different material distribution and storage mechanisms 4 in sequence. After all the raw materials are added, the track suspension drive mechanism 1 drives the overall mixing feeding mechanism 5 to the position of different configuration devices. At the same time, the raw materials in the different material distribution and storage mechanisms 4 are added to the overall mixing feeding mechanism 5 for pre-mixing and then discharged.

[0100] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
