Description

Technical Field

[0001] The invention relates to the technical field of garden maintenance, and more particularly to a garden fallen leaf processing device. Background Art

[0002] The maintenance and management of garden trees is extremely important in greening construction. People often say that three parts of planting and seven parts of maintenance. This maintenance includes two aspects. One is maintenance. According to the different growth needs and specific requirements of trees, timely adopt horticultural technical measures such as fertilization, pruning, prevention and control of pests and diseases, irrigation, intertillage and weeding. The second is management, such as cleaning and maintenance of green spaces and other garden management work. The daily work of cleaning and maintenance is nothing more than collecting and processing the fallen leaves in the garden.

[0003] The existing collection and treatment of garden fallen leaves is different from the previous one. It does not require manual collection. It only needs to aim the adsorption end of the electric leaf collection vehicle at the road surface or the garden green belts on both sides of the street. The fallen leaves can be collected into the corresponding collection bags under the adsorption action of the adsorption structure and the sweeping action of the rotating brooms on both sides. However, when the fallen leaves collection and treatment device collects and treats the fallen leaves, it is easy for the fallen leaves and sand and gravel to enter the device together, resulting in an increase in the subsequent treatment steps for the fallen leaves, affecting the cleaning and collection efficiency.

[0004] In the prior art, there is a Chinese invention patent application with publication number CN114717997A, which discloses a hand-push garden leaf collection and processing device, which drives the rotating shaft to rotate through the rotation of the feeding motor, so that the connecting frame rotates, drives the rotating gear to rotate, and the separation cylinder rotates through the engagement of the rotating gear and the inner gear ring. When the rotating shaft rotates, the feeding paddle is driven to rotate, thereby moving the fallen leaves. The rotation of the separation cylinder allows the sand and dust inside the fallen leaves to fall into the cleaning box through the separation hole, so that the fallen leaves are kept clean, the later processing of the fallen leaves is reduced, and the efficiency of fallen leaf processing is improved.

[0005] Although the fallen leaves collection and processing device provided in the prior art can separate the sand and dust inside the fallen leaves, the position of the collection and processing end is fixed and cannot be adaptively adjusted. The fallen leaves next to the trees are arranged in a circle around the trunks. After cleaning the fallen leaves around them, it is necessary to push the device to make a circular motion for comprehensive cleaning. The arrangement of trees in the garden varies and the number of trees is huge, which makes the cleaning work time-consuming and laborious. Furthermore, when cleaning the fallen leaves on the green belts on both sides of the city streets, the green belts will be raised upward and there will be different height differences depending on the type of shrubs planted, making the collection and processing device provided more difficult to apply.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) Through the linkage driving action of the first electric telescopic rod and the third servo motor installed in the outward turning adjustment mechanism, the pipe mouth of the telescopic guide tube used for adsorbing fallen leaves can be adjusted in real time. In conjunction with the fourth servo motor of the bevel adjustment mechanism, the adsorption end can be extended outward and turned over as needed, moving like a snake, driving the pipe mouth of the telescopic guide tube to surround the outside of the tree trunk from both ends for adsorption. The fallen leaves in the inner side of the area can be completely cleaned up without the need for a moving device, which effectively solves the problem that the fallen leaves collection and processing device provided in the prior art is difficult to completely clean up the fallen leaves around the tree.

[0021] (2) The first servo motor installed in the lifting mechanism can utilize the rotation of the gear rotating rod at its output end to drive the outward adjustment mechanism and the bevel adjustment mechanism on the outside of the gear track sleeve to be lifted and lowered synchronously, so that the retractable guide tube used for adsorption can be lifted to a certain height to process the fallen leaves on the outside of trees with height differences, further improving the adaptability of the fallen leaf collection and processing device, that is, it can efficiently process fallen leaves with height differences in complex garden environments, and can also adapt to green belts of different heights on both sides of the street.

[0022] (3) The second servo motor on the outside of the lifting mechanism can be used to drive the bidirectional threaded rod at its output end to rotate, so that the outer eversion adjustment mechanism can be synchronously expanded or approached to the left and right sides along the inner wall of the square cavity box, and the approach state of its retractable guide tube can be changed in real time. In the process of absorbing and collecting fallen leaves, it can adapt to trees of different thicknesses and can be adaptively inserted into shrubs in the green belt, so that the adaptability of the device is further improved.

[0023] (4) In conjunction with the side-changing mechanism on the outside of the base frame, the retractable guide tube on the outside of the L-shaped sleeve can be rotated around the platform support plate by loosening the tightening bolts on the outside of the tightening threaded sleeve. When the device is pushed to absorb fallen leaves, the adsorption end can be swung to the left and right to fit in different directions. The adsorption direction can be adjusted at will without changing the pushing direction of the device. The adsorption end can also be arranged at right angles to collect and process the fallen leaves on the front side of the device, so that the adsorption end can be further switched according to the use environment.

[0024] (5) Through the leaf mold making mechanism installed on the surface of the base frame, in cooperation with the retractable guide tube on the outside of the adsorption module, different layers of drawers can be inserted on the outside of the socket according to the needs of leaf litter processing, and the collected leaves can be arranged in layers of soil and leaves. Leaf mold can be directly made without transferring it again, and it can be superimposed in real time according to the actual collection situation, effectively reducing the workload of converting leaves into fertilizer.

[0025] (6) The detachable pipe head mechanism assembled on the outside of the retractable guide tube can cut and break the fallen leaves sucked into the processing box through the high-speed rotation of the cutting knife at the output end of the stirring motor during the actual collection process. This can ensure that the fallen leaves are more thoroughly combined with the soil when making leaf mold and are more easily absorbed by the soil. At the same time, it can also prevent foreign objects such as branches from being stuck at the adsorption end and affecting the smoothness of collection. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0046] See also Figures 1 to 8 A garden leaf litter processing device comprises a base frame 1, a side-changing mechanism 3 is installed on the front side of the base frame 1, an adsorption module 4 is installed on the upper surface of the side-changing mechanism 3, a lifting mechanism 5 is installed on the outer side of the side-changing mechanism 3, and corresponding eversion adjustment mechanisms 6 and bevel adjustment mechanisms 7 are installed on both sides of the lifting mechanism 5, and a leaf mold making mechanism 12 corresponding to the conveying end of the adsorption module 4 is installed on the upper surface of the base frame 1;

[0047] Among them, the adsorption ends on the left and right sides of the outer surface of the adsorption module 4 are fixedly connected with retractable catheters 8, and the outer side of the retractable catheter 8 passes through the adjustment end of the bevel adjustment mechanism 7. Through the eversion adjustment effect of the eversion adjustment mechanism 6 and the bevel adjustment effect of the bevel adjustment mechanism 7, the adsorption tube head can be moved around the tree trunk for surrounding adsorption, and cooperate with the lifting mechanism 5 to adapt to green belts with different height differences. The switching effect of the side-changing mechanism 3 can be used to adjust the direction of the adsorption end in real time according to the use environment, so that it can adapt to green belts in different directions to adsorb fallen leaves.

[0048] In the actual process of garden tree maintenance and management, the arrangement of fallen leaves handled by the staff is not uniform, and due to the particularity of their falling, most of the fallen leaves are actually arranged around the main trunk. Therefore, when collecting them with the hand-pushed fallen leaf collector in the prior art, it is necessary to push the device to move in a circle around the trunk to be able to collect them thoroughly. It is okay for relatively flat gardens, but it is impossible to use the collection vehicle to collect garden trees with high and low drops. Secondly, there are also fallen leaves that need to be collected on the green belts commonly seen in gardens or streets, but the green belts are generally distributed on both sides of the road and have high and low drops. At this time, it is also difficult for the collection vehicle to assist in collection, so it is necessary to adopt the above-mentioned technology. A technical solution is provided to solve the problem that the leaf collection and processing device provided in the prior art is difficult to thoroughly clean the fallen leaves around trees and is difficult to be applied to the green belts on both sides of urban streets and in garden landscapes. That is, first, the end of the device used to absorb the fallen leaves is lifted upward by the lifting mechanism 5 to adapt to the environment with different height differences for work, and during the working process, the linkage and cooperation of the eversion adjustment mechanism 6 and the bevel adjustment mechanism 7 can be utilized to control the retractable catheter 8 at its port to adjust the direction and extension position of the adsorption end in real time, which can be expanded outward and bent and retracted, and the catheter can be extended like a snake to collect the fallen leaves at different positions, effectively solving the problem that the fallen leaves in the dead corners are difficult to clean.

[0049] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the side-changing mechanism 3 includes a platform support plate 31 fixedly connected to the bottom position of the front side of the base frame 1, and an L-shaped sleeve plate 32 is movably provided on the upper surface of the platform support plate 31. The lifting mechanism 5 includes side plates 51 fixedly connected to the left and right sides of the upper and lower ends of the outer surface of the L-shaped sleeve plate 32, and gear rotating rods 52 are movably installed on the inner wall sides of the side plates 51. The outer surface of the gear rotating rod 52 is meshed with a corresponding gear track sleeve 54. A first servo motor 53 is fixedly installed on the outer surface of the upper side plate 51 of the outer side of the L-shaped sleeve plate 32, and the output end of the first servo motor 53 passes through its side plate 51 and is fixedly connected to the gear rotating rod 52 on the inner wall side. A square cavity box 55 is fixedly connected to the bottom position of the outer side surface of the gear track sleeve 54, and a bidirectional threaded rod 57 is movably installed inside the square cavity box 55. A second servo motor 56 is fixedly connected to the left side of the square cavity box 55, and the output end of the second servo motor 56 passes through the side of the square cavity box 55 and is fixedly connected to the bidirectional threaded rod 57.

[0050] like Figure 1 , Figure 4 , Figure 5As shown, the outward turning adjustment mechanism 6 includes a nut clamp 61 slidably installed at the symmetrical positions on the left and right sides of the square cavity box 55, the nut clamp 61 is meshed with the bidirectional threaded rod 57, the outer side of the nut clamp 61 is fixedly connected with a first U-shaped sleeve 62, the first U-shaped sleeve 62 is movably installed with a first flip block 63 at the rear side of the inner wall opening, the first U-shaped sleeve 62 is movably installed with an outward turning partition 64 at the front side of the inner wall opening, the second flip block 65 is movably installed at the middle position of the side of the outward turning partition 64, and the outer surface of the first flip block 63 is fixed A first electric telescopic rod 66 is installed, and the output end of the first electric telescopic rod 66 is fixedly connected to the second flip block 65. The second U-shaped sleeve 67 is movably installed on the end of the outward-turned partition 64 away from the first U-shaped sleeve 62. An L-shaped motor support plate 68 is fixedly installed on the upper surface of the outward-turned partition 64. A third servo motor 69 is fixedly installed on the upper surface of the L-shaped motor support plate 68. The third servo motor 69 corresponds to the movable hinged end of the outward-turned partition 64 and the second U-shaped sleeve 67 above and below, and the bottom output end of the third servo motor 69 is fixedly connected to the upper surface of the second U-shaped sleeve 67.

[0051] As described in the above embodiments, the actual collection process needs to face different complex environments. Since the collection end is connected to a corresponding storage module, it is large in size and inconvenient to move with the complex environment. Therefore, by adopting the above technical solution, first, according to the actual height of the collection end required, the first servo motor 53 is turned on, and the gear track sleeve 54 is synchronously driven to move through the rotation of the gear rotating rod 52 at the output end of the first servo motor 53. The first servo motor 53 controls its gear rotating rod 52 to rotate back and forth regularly, so as to control the square cavity box 55 on the front side of the gear track sleeve 54. The front side surface rotates straight up and down to raise the height of the adsorption end of the device in real time. In order to adapt to the thickness of different trees and the intervals of bushes on different green belts, the bidirectional threaded rod 57 at the output end of the second servo motor 56 can be rotated to drive the eversion adjustment mechanism 6 to expand or approach, change the degree of fit of the telescopic guide tube 8 arranged on its outer side, and can fit the trunk and the root of the bush as much as possible during the process of adsorbing fallen leaves, and adsorb the fallen leaves in the dead corner. In addition, in order to deal with the fallen leaves arranged in a circle around the trunk, the first U-shaped sleeve plate 62 can be used to adjust the height of the adsorption end of the device in real time. The first electric telescopic rod 66 has an electric telescopic effect, and because both sides of the first electric telescopic rod 66 are fixed by the first flip block 63 and the second flip block 65, the outward-turned partition plate 64 can be pulled outward to rotate during the telescopic movement, and the rotation position of the second U-shaped sleeve plate 67 can be changed, so that the second U-shaped sleeve plate 67 can be rotated at different positions under the driving action of the third servo motor 69, so that the telescopic guide tube 8 fixed by the bevel adjustment mechanism 7 can be moved outward to different positions, and the telescopic guide tube 8 at its port can be controlled to adjust the direction of the adsorption end in real time. The outer cover 64 can be rotated 60 degrees inward from 180 degrees under the pulling action of the first electric telescopic rod 66, so that the rotation axis of the second U-shaped sleeve 67 is offset 60 degrees inward. At the same time, the second flip block 65 can be driven by the third servo motor 69 to rotate back and forth 60 degrees to adjust the position of the outer end bevel adjustment mechanism 7 in real time.

[0052] like Figure 1 , Figure 4 , Figure 5As shown, the bevel adjustment mechanism 7 includes a fourth servo motor 71 fixedly mounted on the upper surface of the second U-shaped sleeve 67 away from one end of the third servo motor 69, a support rod 72 penetrating the surface of the second U-shaped sleeve 67 is fixedly mounted at the bottom output end of the fourth servo motor 71, a U-shaped frame 73 is fixedly connected to the bottom of the support rod 72, a tube ring frame 74 is movably mounted inside the U-shaped frame 73, an outward-expanding U-shaped plate 76 is fixedly connected to the middle position of the upper rear side of the tube ring frame 74, a third flip block 77 is movably mounted on the rear side of the outward-expanding U-shaped plate 76, a fourth flip block 78 is movably mounted at the upper rear side of the surface of the support rod 72, a second motor telescopic rod 79 is fixedly mounted on the surface of the fourth flip block 78, and the output end of the second motor telescopic rod 79 is fixedly connected to the third flip block 77.

[0053] As described in the above embodiment, when the telescopic conduit 8 is extended to the corresponding position according to the environment, the position of the adsorption end is actually still fixed, that is, the direction of the tube mouth of the telescopic conduit 8 remains unchanged, resulting in a dead angle in the adsorption opening. Therefore, it is necessary to adopt the above technical solution and utilize the rotation of the fourth servo motor 71 to drive the support rod 72 to rotate so that the telescopic conduit 8 can change the direction of its opening. Further, under the motor telescopic action of the second motor telescopic rod 79, the outward expansion U-shaped plate 76 can be pulled. Since both ends of the U-shaped plate 76 are connected by the third flip block 77 and the fourth flip block 78, the U-shaped plate 76 can be pulled outward. The block 78 is fixed and movable, so the tube ring frame 74 can be driven to rotate around the inner wall of the U-shaped frame 73 while being telescopically pulled. During the up and down rotation of the tube ring frame 74, the adsorption opening of the telescopic conduit 8 can be driven to adjust up and down and change its position. During the actual cleaning process, the telescopic conduit 8 can be lifted up a certain distance so that it does not directly contact the ground. Instead, the adsorption opening of the telescopic conduit 8 is tilted downward through the up and down rotation of the tube ring frame 74, which can not only provide a better adsorption stage, but also avoid the inhalation of debris and dust.

[0054] like Figure 1 , Figure 4 , Figure 5 As shown, a bolt sleeve 75 is provided at the middle position of the bottom of the bundle tube ring frame 74, and corresponding tightening bolts are rotatably installed inside the bolt sleeve 75. The outer side surface of the side plate 51 is fixedly connected to the limiting top plate 58, and the limiting top plate 58 is fitted and corresponds to the square cavity box 55. A spacer ring for housing the bidirectional threaded rod 57 is fixedly installed at the middle position inside the square cavity box 55, and universal wheels 2 are fixedly installed at the four side corners of the bottom of the base frame 1.

[0055] Among them, the bolt sleeve 75 at the bottom of the tube ring frame 74 can be screwed with the corresponding temporary bolts, and the retractable conduit 8 on the inner wall side can be pushed upward by the bolts, which can not only realize convenient disassembly, but also adapt to adsorption conduits of different sizes by changing its lifting length. The limiting top plate 58 installed on the upper and lower ends of the outer surface of the side plate 51 can be used to limit the lifting mechanism 5 during the lifting process, that is, the lifting process of the square cavity box 55, so that it can only be lifted and moved at the front side of the corresponding end, so as to avoid it causing the square cavity box 55 to over-turn, and the universal wheel 2 is used to push the device.

[0056] like Figure 1 , Figure 3 As shown, the bottom of the L-shaped sleeve 32 is fixedly connected to a chuck sleeve 33, and the chuck sleeve 33 is movably installed at the surface position of the platform support plate 31. The bottom side position of the chuck sleeve 33 is fixedly connected to a tightening threaded sleeve 34 that is consistent with the direction of the side plate 51, and the bottom left and right sides and the front middle position of the platform support plate 31 are provided with positioning screw holes 35 corresponding to the tightening threaded sleeve 34.

[0057] As described in the above-mentioned embodiment, during the actual collection process, the staff needs to deal with different positions. For the green belts on both sides of the road, especially the green belts on both sides of the trail, it is not convenient to push back and forth in the opposite direction. If the adsorption module 4 is set on a single side to collect the fallen leaves, it is necessary to change the direction of its pushing to control the adsorption area, which is not convenient. By adopting the above-mentioned technical solution, the tightening bolts on the bottom of the tightening threaded sleeve 34 are loosened, and the fixed state between it and the positioning screw 35 is cancelled. The chuck sleeve 33 can be rotated according to needs, so that the L-shaped sleeve 32 can be rotated on the upper surface of the platform support plate 31, and can be positioned and fixed at three sides in front and on the left and right sides. When it is rotated to the side that needs to be cleaned, the corresponding bolts can be assembled again by tightening the threaded sleeve 34.

[0058] like Figure 1 , Figure 7 , Figure 8 As shown, a processing box 11 is fixedly installed on the upper surface of the base frame 1, and the conveying end of the adsorption module 4 is fixedly connected to a conveying pipe 10 which is communicated with the upper part of the processing box 11. The leaf mold making mechanism 12 includes sockets 125 which are arranged on the rear side of the processing box 11 from top to bottom, and corresponding slot frames 121 are arranged on the inner wall sides of the sockets 125, and corresponding drawer grids 123 are inserted and installed inside the slot frames 121.

[0059] like Figure 1 , Figure 7 , Figure 8As shown, a plurality of opening grooves 124 are sequentially arranged at the bottom of the drawer grid 123, a plurality of brush heads 122 are sequentially arranged and fixedly installed at the upper and lower ends of the inner wall of the socket 125, a water supply module 15 is fixedly installed on the upper surface of the processing box 11, and the bottom water supply end of the water supply module 15 penetrates into the inner top of the processing box 11, a visible window panel 13 is fixedly installed on the side of the processing box 11, and a push rod 14 is fixedly connected to the rear side of the upper surface of the processing box 11.

[0060] Among them, the adsorption module 4 is an adsorption structure assembled on a collection vehicle in the prior art, and its working principle is similar to that of a vacuum cleaner, with an adsorption end and an output end. The water supply module 15 is a pressurized spray structure in the prior art, which is provided with a corresponding transparent water tank and a pressurized motor, and its conveying pipe 10 penetrates into the port on one side of the top of the processing box 11 as an outward-expanding opening, which can be evenly sprayed into the interior of the processing box 11 during the conveying process.

[0061] As described in the above-mentioned embodiment, in the process of garden leaf processing, most of the collected fallen leaves are converted into fertilizers. If the fallen leaves are directly piled at the roots of plants, there may be pathogens in the fermentation process of the fallen leaves, which may easily cause plant diseases and insect pests, so they need to be collected and processed separately. The simplest method is generally to naturally pile and ferment them in combination with soil. According to the above-mentioned technical scheme, after the fallen leaves are adsorbed by the retractable guide tube 8 of the adsorption module 4, they are transported to the interior of the processing box 11 through the conveying pipe 10. Before transportation, the corresponding old soil can be loaded into the drawer grid 123 inserted in the internal slot frame 121 of the socket 125. The interior of the processing box 11 can be directly observed through the visible window panel 13 on the side. When the fallen leaves piled on the surface of the old soil of the internal drawer grid 123 are sufficient, Another drawer compartment 123 filled with old soil is inserted into the socket 125 on the upper side thereof, and the same process is repeated upwards. In the process of collecting fallen leaves, old soil can be taken on the spot and loaded into the drawer compartment 123, and then inserted into the processing box 11 to be mixed with the fallen leaves to directly make leaf mold, so that the old soil can regain its fertility and become fertile and good soil. In addition, an open groove 124 is provided at the bottom of each drawer compartment 123. With the spraying effect of the water supply module 15, water can be appropriately added to the surface of the leaf mold. When the fallen leaves are relatively dry, a layer can be piled up and watered to keep the dead branches and leaves moist, which will ferment faster. In addition, a brush head 122 separated from the upper and lower parts is installed on the outer side of each socket 125, and a sealing edge net can be formed at the socket 125, which can effectively prevent the fallen leaves inside from being pulled out when the drawer compartment 123 is pulled.

[0062] like Figure 1 , Figure 4 , Figure 6As shown, a detachable tube head mechanism 9 is installed on the outside of the telescopic catheter 8. The detachable tube head mechanism 9 includes a threaded sleeve 91 rotatably installed on the outside of the telescopic catheter 8. The outer surface of the threaded sleeve 91 is fixedly connected to an outward-expanding tube head 95. The outward-expanding tube head 95 is an inward-retracting conical cover structure as a whole.

[0063] like Figure 1 , Figure 4 , Figure 6 As shown, a frame plate 92 is fixedly installed at the inner rear position of the external expansion pipe head 95, a stirring motor 93 is fixedly installed at the rear axial position of the frame plate 92, and a cutting knife 94 is fixedly installed at the output end of the stirring motor 93.

[0064] As described in the above-mentioned embodiment, in the process of garden fallen leaves processing, in order to prevent debris and impurities from following the fallen leaves and being adsorbed into the interior of the processing box 11 through the telescopic conduit 8, the bevel adjustment effect of the bevel adjustment mechanism 7 is used to tilt the pipe mouth of the telescopic conduit 8 downward to avoid direct contact with the ground, thereby preventing the conduit mouth from shoveling up debris and foreign matter on the ground, effectively separating the debris, but foreign matter may still be sucked into the interior, causing the adsorption end to be blocked. Therefore, through the above-mentioned technical scheme, the threaded sleeve 91 can be rotatably installed on the outside of the telescopic conduit 8 during operation, and the rotation of the cutting knife 94 at the output end of the stirring motor 93 can be used to clean up foreign matter at the adsorption end in real time, and the outward expansion effect of the outward expansion pipe head 95 can be used to improve the safety of the adsorption end. Secondly, it can be disassembled in real time through the rotational installation effect of the threaded sleeve 91, which is convenient for replacement and maintenance.

[0065] Instructions for use: First, according to the cleaning direction and actual environment, loosen the tightening threaded sleeve 34 fixed at the bottom of the side-changing mechanism 3, and use the chuck sleeve 33 to rotate the whole body so that one end of the retractable guide tube 8 faces the area to be cleaned, and then drive the gear track sleeve 54 through the first servo motor 53 installed by the lifting mechanism 5 to drive the whole body to lift upward to adapt to the environment with different height differences. During the adsorption process, the eversion adjustment function of the eversion adjustment mechanism 6 and the bevel adjustment function of the bevel adjustment mechanism 7 are used to control the retractable guide tube 8 at both ends of its outer side to bend outward and inward, and the adsorption angle is changed in real time with the adjustment function of the fourth servo motor 71, so as to effectively clean up the fallen leaves in the dead corner. When the fallen leaves are adsorbed into the interior of the processing box 11, it is only necessary to observe the installation sequence of the visual window plate 13 and insert it into the corresponding drawer grid 123 to form soil for making leaf mold, so that the old soil can regain its fertility and become fertile and good soil.

[0066] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
