Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mineral conveying and processing, in particular to a mineral soil conveying and lifting device. BACKGROUND

[0002] In the mining, metallurgy, building materials and other industries, belt conveying equipment is widely used in continuous conveying of bulk materials. It is a belt conveyor mainly used for continuous conveying of mineral soil and ore in the inclined direction, which can convey the material obliquely upward to a higher processing bin, crushing bin or next processing equipment.

[0003] The existing patent application with the patent publication number CN220885701U and the publication date of May 3, 2024 is named "Lime ore conveying belt pressing device". The patent comprises a conveying belt support frame, a conveying belt, and a plurality of pressing mechanisms arranged on the conveying belt support frame along the conveying direction of the conveying belt for pressing the conveying belt; each pressing mechanism comprises two protection boxes and a pressing roller arranged in the protection box. The utility model is provided with a step groove on the pressing roller, which can cross the accumulated soil on the conveying belt during the rolling process of the pressing roller, reducing the contact between the pressing roller and the soil and other impurities, and reducing the wear of the pressing roller and the conveying belt. At the same time, it reduces the impact of impurities on the conveying efficiency of the conveying belt; the protection box can protect the pressing roller from being impacted by lime ore, prolonging the service life of the pressing roller.

[0004] The above-mentioned application has the following deficiencies: during operation, the conveying belt is easily affected by factors such as uneven distribution of material, roller installation error, and tension fluctuation, resulting in deviation. Deviation not only causes material to spill and equipment wear to intensify, but also can cause the conveying belt to tear or stop working, affecting production efficiency and operational safety. Common anti-deviation devices use blocking rollers or pneumatic and electric detection and correction mechanisms. Fixed blocking rollers are simple in structure, but long-term frictional contact with the edge of the conveying belt can easily cause belt wear. Automatic correction systems based on sensors are complex in structure, high in cost, and poor in environmental adaptability, especially in harsh conditions such as dust and humidity, which reduces reliability. In addition, existing correction devices mainly focus on lateral limiting, and it is difficult to maintain the grooving of the conveying belt bearing surface during correction, affecting the stability and carrying capacity of material transportation.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0032] Please see Figures 1-8 This invention provides a mineral conveying and lifting device, including a frame 1 and a conveyor belt 2 mounted on the frame 1, and a support roller 3 mounted on the frame 1 via a support frame 4. The top of the support roller 3 contacts the inner wall of the conveyor belt 2, and anti-deviation pushing components 5 are slidably sleeved at both ends of its roller shaft. A pair of correction rollers 6 are symmetrically rotated and mounted on both sides of the support frame 4 to squeeze the edge of the conveyor belt 2 to form a material trough 201 on the bearing surface. Anti-detachment transmission rings 7 are slidably sleeved on the correction rollers 6 and rotate synchronously with them. A transmission adjustment mechanism 8 is mounted on the inner wall of the support frame 4 and is connected to the anti-detachment transmission rings 7 and the anti-deviation pushing components 5 respectively. When the conveyor belt 2 deviates and pushes the anti-detachment transmission ring 7 into contact with the transmission adjustment mechanism 8, the transmission adjustment mechanism 8 drives the anti-deviation pushing components 5 to act on the inclined surface of the conveyor belt 2 and push it towards the center.

[0033] Specifically, frame 1, as the main support structure, is constructed from welded or bolted steel sections, providing sufficient rigidity and stability. Conveyor belt 2 is made of high-strength rubber with embedded tensile fibers or steel wire ropes to enhance tensile strength. Its width is designed according to conveying capacity requirements. Conveyor belt 2 is tensioned and driven by head and tail rollers, forming a closed-loop operating path. Support rollers 3 consist of multiple sets of parallel rollers, their surfaces covered with wear-resistant rubber to reduce friction. Support rollers 3 are mounted on support frame 4 via bearing seats. Support frame 4 has an inverted U-shaped structure and is bolted to the beams of frame 1. The top of support rollers 3 contacts the inner wall of conveyor belt 2, jointly supporting the weight of the material. A pair of anti-deviation pushing components 5 are respectively sleeved on both ends of the support roller 3's roller shaft and can slide axially. The contact surface of the anti-deviation pushing components 5 is an inclined plane. Matching the inclined surface of the conveyor belt 2, i.e. the sidewall of the trough 201, a pair of correcting rollers 6 are symmetrically installed on both sides of the support frame 4, located on the side below the conveyor belt 2. The correcting rollers 6 are short rollers with a surface covered with high friction coefficient rubber. They are connected to the side wall of the support frame 4 through bearings. The anti-detachment transmission ring 7 rotates synchronously with the correcting rollers 6, but can slide axially. The outer side of the anti-detachment transmission ring 7 is used to contact the transmission adjustment mechanism 8. The transmission adjustment mechanism 8 corresponds to the outer edge of the anti-detachment transmission ring 7. When the anti-detachment transmission ring 7 moves axially, it drives the transmission adjustment mechanism 8 to operate. Then, the transmission adjustment mechanism 8 pushes the anti-deviation pushing component 5, so that the anti-deviation pushing component 5 applies force from the inclined surface of the inner wall of the conveyor belt 2. The conveyor belt 2 runs under the support of the support rollers 3, and the material is concentrated in the middle of the belt surface.The symmetrically arranged correction rollers 6 slightly press against the edge of the conveyor belt 2, causing it to bend upwards to form a stable trough 201. At this time, there is a certain gap between the anti-detachment drive ring 7 and the conveyor belt 2. When the anti-detachment drive ring 7 does not contact the transmission adjustment mechanism 8, the anti-deviation pushing component 5 does not move. When the conveyor belt 2 shifts to one side due to uneven load, material sticking to the roller, or vibration of the frame 1, the anti-detachment drive ring 7 on the correction roller 6 on that side is squeezed by the edge of the conveyor belt 2, causing the anti-detachment drive ring 7 to slide outward along the roller surface. If the anti-detachment drive ring 7 contacts the transmission adjustment mechanism 8 at this time, the transmission adjustment mechanism 8 will convert the rotational motion of the correction roller 6 into the translational motion of the anti-deviation pushing component 5. The anti-deviation pushing component 5 on that side moves along the roller shaft of the support roller 3 and then contacts the inclined surface of the edge of the conveyor belt 2. That is, the material trough 201 is blocked by the side and a horizontal component force is applied inward. Since the anti-deviation pushing component 5 acts on the inclined surface rather than the edge of the conveyor belt 2, the force direction is consistent with the deformation direction of the belt surface, effectively pushing the conveyor belt 2 towards the center, while avoiding scraping the belt edge. When the conveyor belt 2 returns to the center position, the anti-detachment transmission ring 7 on the correction roller 6 is no longer squeezed by the conveyor belt 2, and it is disengaged from the transmission adjustment mechanism 8. The anti-deviation pushing component 5 stops pushing and moves outward under the gravity of the ore. The correction roller 6 continues to lightly press the belt edge to maintain the shape of the material trough 201, ensuring that the material is conveyed in the center. The correction force acts on the inclined area of ​​the belt surface, making full use of the structural strength of the material trough 201, significantly reducing belt edge wear, extending the life of the conveyor belt 2, and ensuring conveying efficiency and stability.

[0034] Compared with the prior art, the embodiments of the present invention maintain the shape of the trough 201 on the conveyor belt 2 by setting symmetrically arranged correction rollers 6, and through the cooperation of the anti-detachment transmission ring 7 and the transmission adjustment mechanism 8, once the conveyor belt 2 deviates and contacts the anti-detachment transmission ring 7, the transmission adjustment mechanism 8 can be triggered immediately to push the conveyor belt 2 back to the center. The anti-deviation pushing component 5 acts on the inclined surface of the conveyor belt 2, that is, the edge part forming the trough 201, instead of directly rubbing the fragile belt edge, which greatly reduces the wear of the conveyor belt 2 during the correction process, extends its service life, and ensures the shape stability of the trough 201 while correcting the deviation, thereby ensuring improved conveying efficiency and reliability. It not only effectively suppresses deviation but also reduces active wear and improves the equipment's adaptability to complex working conditions.

[0035] In a further embodiment of the present invention, a storage bin 101 is provided on one side of the frame 1, and a receiving frame 102 located below the storage bin 101 is installed on the conveyor belt 2. The two sides of the receiving frame 102 are in contact with the top surface of the conveyor belt 2. The receiving frame 102 is a U-shaped structure with one open end, its two sides are inclined, and its height is slightly higher than the height of the side guards formed by the upward turning of the two sides of the conveyor belt 2. The outer side of the receiving frame 102 is in close contact with the surface of the conveyor belt 2. Specifically, when the material falls from the storage bin 101, it first enters the area of ​​the receiving frame 102. The upright plates on both sides of the receiving frame 102 form a guiding effect to prevent the material from impacting and spreading, and ensure that the material falls in the central area of ​​the conveyor belt 2. At the same time, the contact between the receiving frame 102 and the belt surface avoids the material from directly scouring the edge of the conveyor belt 2, reducing wear, controlling the material distribution from the source, reducing the probability of the conveyor belt 2 running off-center due to uneven loading, and improving the stability of the feeding process.

[0036] In a further embodiment of the present invention, the correction roller 6 is inclined, and a bushing 601 is slidably sleeved on one end of the roller shaft of the correction roller 6. The bushing 601 and the roller shaft of the correction roller 6 rotate coaxially. A plurality of annularly distributed connecting claws 602 are fixedly connected to the bushing 601. One side of the anti-detachment transmission ring 7 is in frictional engagement with the edge of the conveyor belt 2, and the other side is fixedly connected to a connecting seat 701 for the connecting claws 602 to be inserted. The connecting claws 602 are inserted into the connecting seat 701 to achieve a sliding engagement. Specifically, the inclined correction roller 6 squeezes the conveyor belt 2 from the edge of the conveyor belt 2 so that the two sides of the bearing surface of the conveyor belt 2 are raised to form a trough 2. 01. The side guard enhances the effect and stability of the material trough 201. When the conveyor belt 2 deviates towards one side of the correction roller 6, it will squeeze the anti-detachment transmission ring 7 on the correction roller 6, causing it to move outward along the axial direction on the correction roller 6. The connecting claw 602 and the connecting seat 701 cooperate with each other, so that the bushing 601, which rotates synchronously with the roller shaft of the correction roller 6, always drives the anti-detachment transmission ring 7 to rotate. When the anti-detachment transmission ring 7 continues to rotate after moving outward a certain distance, it can control the anti-deviation pushing component 5 to move inward to push the conveyor belt 2 through the contact transmission adjustment mechanism 8, thereby achieving the purpose of rapid adaptive correction when the conveyor belt 2 deviates.

[0037] In a further embodiment of the present invention, the anti-deviation pushing component 5 includes a sleeve 501 sleeved on the roller shaft of the support roller 3. A limit ring 301 is fixedly sleeved on the roller shaft of the support roller 3. A top spring 502 that abuts against the limit ring 301 is fixedly connected to one end of the sleeve 501. A wedge-shaped pressing block 503 is fixedly connected to the top of the sleeve 501. The inclination angle of the wedge-shaped pressing block 503 is consistent with the inclination angle of the sidewall of the conveyor belt 2. Wear-resistant plates are embedded on its surface. A diagonal brace 504 that is slidably connected to the support frame 4 is fixedly connected to the bottom of the sleeve 501. A horizontal groove for the diagonal brace 504 to be inserted is opened in the support frame 4. Specifically, during normal operation, the top spring 502 pushes the sleeve... 501 is moved away from the support roller 3, so that the wedge-shaped pressing block 503 maintains a certain gap with the side of the conveyor belt 2. When correction is required, the sleeve 501 is pushed by the transmission adjustment mechanism 8 to slide along the roller shaft and compress the top spring 502. The inclined surface of the wedge-shaped pressing block 503 contacts the inclined surface of the side of the conveyor belt 2, converting the axial thrust into the horizontal component in the center, and maintaining the inclination angle of the edge of the conveyor belt 2 to avoid excessive pressure on the conveyor belt 2 and causing damage. The inclined support rod 504 is guided in the slide groove of the support frame 4 to ensure the accurate direction of the thrust. The top spring 502 provides the reset force. After the correction is completed, the anti-deviation pushing component 5 automatically returns to its position after the edge of the conveyor belt 2 no longer contacts the anti-detachment transmission ring 7.

[0038] In a further embodiment of the present invention, the transmission adjustment mechanism 8 includes a transmission rod 801 rotatably mounted on the inner wall of the support frame 4. A bevel gear 802 is fixedly connected to the top of the transmission rod 801. A bevel gear ring 702 that meshes with the bevel gear 802 is fixedly connected to one side of the anti-detachment transmission ring 7. A transmission gear 804 is rotatably connected inside the support frame 4. The bottom of the transmission rod 801 is connected to the transmission gear 804 in the opposite direction. A rack 505 that meshes with the transmission gear 804 is fixedly connected to the other end of the sleeve 501. A first pulley 805 is fixedly connected to the bottom end of the transmission rod 801. A second pulley 806 is fixedly connected to the bottom of wheel 804. The first pulley 805 and the second pulley 806 are connected by a cross drive belt 807. Specifically, when the conveyor belt 2 deviates, it pushes the anti-detachment drive ring 7 to slide axially along the correction roller 6. The bevel ring 702 on the anti-detachment drive ring 7 moves accordingly until the bevel ring 702 meshes with the bevel gear 802. The bevel ring 702, which rotates together with the anti-detachment drive ring 7, drives the bevel gear 802 to rotate. The bevel gear 802 drives the transmission rod 801 to rotate. The first pulley 805 at the bottom of the transmission rod 801 is connected by a cross drive belt 807. The cross belt 807 drives the second pulley 806 to rotate. The cross belt arrangement makes the rotation direction of the second pulley 806 opposite to that of the first pulley 805, achieving a reversal of the motion direction. The second pulley 806 drives the transmission gear 804 to rotate in the opposite direction. The transmission gear 804 meshes with the rack 505, converting the rotational motion into the linear motion of the rack 505. The rack 505 pushes the sleeve 501 to slide along the axial center of the support roller 3, thereby applying a corrective force to the conveyor belt 2 from one side through the wedge-shaped pressure block 503. This transmission mechanism, through the bevel gear 802 and the cross belt 807, drives the second pulley 806 to rotate. The transmission 7 enables precise control of the direction of motion. The arrangement of the cross transmission belt 807 ensures that the direction of the correction thrust is opposite to the direction of the offset. The entire process does not require external power and is driven entirely by the mechanical energy of the conveyor belt 2 offset, achieving adaptive correction. The cross transmission belt 807 also plays a role in buffering and overload protection to avoid damage to the mechanism. Only when the conveyor belt 2 offsets to a certain extent will the conical toothed ring on the anti-detachment transmission ring 7 mesh with the bevel gear 802 on the transmission rod 801 to transmit power, thus preventing the conveyor belt 2 from being continuously impacted and squeezed by the anti-offset pushing component 5.

[0039] In a further embodiment of the present invention, the two ends of the support roller 3 are rotatably connected to the two sides of the inner wall of the support frame 4, respectively. Movable cavities 302 are provided on both sides of the support roller 3. Several elastic inserts 303 are distributed in a ring on both sides of the support roller 3. One end of each elastic insert 303 is inserted into the movable cavity 302, and a return spring is installed between this end and the movable cavity 302. A pressure plate 304 is installed in the movable cavity 302. One side of the pressure plate 304 is inclined against each elastic insert 303, and the other end is fixedly connected to a connecting rod 305 that passes through the support roller 3 shaft. A lever 306 is installed on one end of the connecting rod 305 outside the support roller 3 shaft. The sleeve 5... One end of 01 abuts against the lever 306. Specifically, during normal operation, the return spring 308 keeps each elastic insert 303 in a retracted state, with the outer end of the insert maintaining contact with the conveyor belt 2. The pressure plate 304, under the synchronous pressing of each elastic insert 303, adheres to one side of the inner wall of the movable cavity 302. The connecting rod 305 drives the lever 306 to the initial position. When the conveyor belt 2 deviates and needs correction, the transmission adjustment mechanism 8 pushes the sleeve 501 to slide along the roller shaft of the support roller 3. The end of the sleeve 501 pushes against the lever 306. As the sleeve 501 continues to move, the connecting rod 305 pushes the pressure plate 304 to displace within the movable cavity 302. The inclined surface of the pressure plate 304 presses the end of the elastic rod 303. Due to the inclined surface, the axial movement of the pressure plate 304 is converted into the ejection movement of the elastic rod 303. Multiple elastic rods 303 are ejected simultaneously, forming a ring support array. The ejected elastic rods 303 directly contact the inner wall of the conveyor belt 2, applying a supporting force to the belt surface. This supporting force effectively corrects the local deformation of the conveyor belt 2 and assists the correction action of the anti-deviation pushing component 5, reducing the friction between the conveyor belt 2 and the support roller 3. The even distribution of multiple rods ensures that the support roller 3 can provide support at any time when it rotates. When the correction is completed, the transmission adjustment mechanism 8 resets. The sleeve 501 moves in the reverse direction to release the pressure on the push block 306. The elastic plug 303 retracts into the movable cavity 302 under the action of its own reset spring 308, and maintains a safe gap with the inner wall of the conveyor belt 2 again. The pressure plate 304 returns to its original position under the squeezing of the elastic plug 303. This mechanism achieves active self-alignment through mechanical linkage. During the correction process, it not only applies correction force from the side, but also supports the belt surface from the inside, effectively preventing excessive deformation of the conveyor belt 2 and reducing the large area contact between the conveyor belt 2 and the support shaft during the correction process. The multi-point support design greatly reduces the wear on the conveyor belt 2, extends its service life, and significantly improves the correction accuracy and efficiency.

[0040] In a further embodiment of the present invention, a top block 506 is inserted into the inclined surface of the wedge-shaped pressing block 503. The bottom end of the top block 506 passes through the sleeve 501 and contacts the roller shaft of the support roller 3. A guide groove 307 is provided on the roller shaft of the support roller 3. When the wedge-shaped pressing block 503 moves inward, the bottom end of the top block 506 abuts against the guide groove 307. The top block 506 is also a wedge-shaped structure, and its inclined angle is consistent with the inclined surface of the wedge-shaped pressing block 503. Specifically, during normal operation, the top of the top block 506 is flush with the working surface of the wedge-shaped pressing block 503 under the action of gravity, and the bottom of the top block 506 contacts the roller shaft surface of the support roller 3. Both the wedge-shaped pressing block 503 and the top block 506 maintain a safe gap with the conveyor belt 2. When the conveyor belt 2 deviates and needs to be corrected, the transmission adjustment mechanism 8 pushes the sleeve 501 to slide along the shaft of the support roller 3, and the wedge-shaped pressing block 503 opens. As the top block 506 moves towards the edge of the conveyor belt 2, its bottom moves along the support roller 3 towards the guide groove 307. As the sleeve 501 continues to move, the bottom of the top block 506 enters the guide groove 307. Due to the change in the depth of the guide groove 307, the support roller 3 can intermittently adjust the height of the top block 506 through the guide groove 307 when it rotates, allowing the top block 506 to intermittently push upward to contact the edge of the conveyor belt 2. At the same time, the inclined surface of the wedge-shaped pressing block 503 also begins to contact the edge of the conveyor belt 2. The pushing motion of the top block 506 and the pushing motion of the wedge-shaped pressing block 503 form a compound motion, generating two forces: one is the horizontal component force (correction force) of the inclined surface of the wedge-shaped pressing block 503, and the other is the additional pressing force and vibration force generated by the top block 506, which causes the ore material located at the edge of the conveyor belt 2 to move towards the center, assisting the conveyor belt 2 in correcting its deviation.

[0041] In a further embodiment of the present invention, a plurality of support rollers 103 are rotatably installed inside the frame 1. The support rollers 103 are in contact with the bottom surface of the conveyor belt 2, and anti-detachment rings 104 are sleeved at both ends of the support rollers 103. The outer periphery of the anti-detachment rings 104 is covered with a polyurethane coating. Specifically, the support rollers 103 mainly bear the supporting role of the non-load-bearing surface of the conveyor belt 2, preventing the conveyor belt 2 from sagging excessively due to the weight of the material and its own gravity. Multiple support rollers 103 form a continuous support surface, reducing the running resistance of the conveyor belt 2 and ensuring stable operation. When the conveyor belt 2 deviates slightly, the belt edge gradually approaches the anti-detachment ring 104 at the end of the support roller 103. The increased outer diameter of the anti-detachment ring 104 forms a physical barrier, preventing the conveyor belt 2 from deviating further. When the polyurethane coating comes into contact with the edge of the conveyor belt 2, it generates flexible friction, providing sufficient resistance to prevent deviation while avoiding hard scratches on the belt edge. When the anti-detachment ring 104 comes into contact with the belt edge, the friction of the polyurethane layer generates a guiding force on the conveyor belt 2, assisting the main correction system in pushing the conveyor belt 2 back to the correct position. When the conveyor belt 2 deviates severely, the polyurethane layer of the anti-detachment ring 104 undergoes elastic deformation, absorbing impact energy. At the same time, it provides a clear friction warning to the operator of equipment malfunction. This design prevents direct collision between the conveyor belt 2 and the metal support seat, protecting the structural integrity of the conveyor belt 2. This support system achieves multiple protection functions through a simple mechanical structure, significantly improving the reliability and safety of equipment operation, while reducing maintenance costs and life cycle costs.

[0042] In a further embodiment of the present invention, a buffer spring 703 is installed inside the connecting seat 701. A pad 704 is fixedly connected to one end of the buffer spring 703. The connecting claw 602 is inserted into the connecting seat 701 and abuts against the pad 704. The width of the anti-detachment transmission ring 7 is greater than the thickness of the conveyor belt 2. Specifically, during normal operation of the equipment, the connecting claw 602 on the bushing 601 is inserted into the connecting seat 701 to transmit the rotational motion of the correction roller 6 to the anti-detachment transmission ring 7. The buffer spring 703 allows for slight elastic deformation to absorb the normal vibration of the conveyor belt 2. When the conveyor belt 2 experiences severe shaking or sudden deviation, the anti-detachment transmission ring 7 is squeezed by the edge of the conveyor belt 2, causing the connecting claw 602 to squeeze the pad 704 and compress the buffer spring 703. The anti-detachment transmission ring 7 absorbs impact energy through elastic deformation. Its width is greater than the thickness of the conveyor belt 2, increasing the contact area and forming protective edges on both sides. When the conveyor belt 2 deviates severely, the protective edges always maintain contact with the belt edge, preventing the conveyor belt 2 from detaching from the edge of the anti-detachment transmission ring 7. After the impact, the buffer spring 703 releases its stored elastic potential energy, pushing the anti-detachment transmission ring 7 back to its initial position. The entire buffering process is completed quickly, ensuring timely recovery of the correction function. This design effectively solves the problem of easy damage to rigid transmissions through elastic connection, significantly improving the reliability and service life of the correction system. The anti-detachment design ensures the stability of the correction function under various working conditions, making it particularly suitable for harsh working environments with vibration and impact.

[0043] In a further embodiment of the present invention, offset indicator blocks 401 are movably and inclinedly inserted on the top of both sides of the support frame 4. The inner side of the offset indicator block 401 is in contact with the bushing 601, and the outer side of the offset indicator block 401 is provided with a reflective warning sticker 402. Specifically, when the conveyor belt 2 is in the normal centered position and the bushing 601 of the correction roller 6 has not moved outward, the offset indicator block 401 is in a retracted state under the action of the reset spring 308, and the reflective warning sticker 402 is hidden inside the support frame 4 and does not produce a visual warning. When the conveyor belt 2 deviates, it drives the correction roller 6 and its bushing 601 to move axially. The outer circumferential surface of the bushing 601 pushes the offset indicator block 401 outward, so that the offset indicator block 401 protrudes and the end with the reflective warning sticker 402 protrudes from the outer surface of the support frame 4. Whether it is day or night, the conspicuous reflective stickers can provide obvious visual warnings. Operators can quickly judge the severity of the deviation according to the scale. After the correction system corrects the conveyor belt 2 back to the normal position, the bushing 601 returns to its previous position, and the deviation indicator block 401 automatically retracts under the action of gravity. The warning sign is hidden inside the support frame 4, indicating that the equipment has returned to normal operation.

[0044] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
