[0020] 2.

DETAILED DESCRIPTION

[0040] 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. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0041] See also Figure 1-Figure 12, an irrigation machine for agricultural irrigation, comprising a hose reel 1, a water supply pipe 2 installed in the hose reel 1, a mobile bracket 3 installed on the other side of the water supply pipe 2 and four mobile wheels 4 installed at the bottom of the mobile bracket 3, the upper surface of the mobile bracket 3 is fixedly connected to a battery box 48, the upper surface of the mobile bracket 3 is also connected to a support assembly and a diversion assembly, the upper end of the support assembly is connected to a water spray assembly, a power mechanism and two transmission assemblies, the diversion assembly is connected to the water spray assembly, both ends of the water spray assembly are connected to support plates 6, the output end of the power mechanism is connected to two reversing mechanisms, the other ends of the two reversing mechanisms are respectively matched and aligned with the two transmission assemblies, the two ends of the two transmission assemblies are respectively connected to the two support plates 6, one side of the two support plates 6 is connected to an opening and closing assembly, the other ends of the two opening and closing assemblies are connected to a shielding assembly, the two shielding assemblies are matched and aligned with the water spray assembly, and the power mechanism and the reversing mechanism are electrically connected to the internal power supply of the battery box 48.

[0042] like Figures 1 to 12 As shown, the agricultural irrigation machine of the present invention can be used according to the following steps:

[0043] 1. First, place the hose reel 1 at one end of the irrigation plot, use traction to drag the water supply pipe 2 wrapped around the hose reel 1 and the mobile bracket 3 and mobile wheel 4 connected to the water supply pipe 2 to the other end of the plot, and then connect the water source to the end of the water supply pipe 2 close to the hose reel 1 and reach a certain working water pressure.

[0044] 2. The water source will then enter the diversion component through the water supply pipe 2, and then enter the water spray component from the diversion component, so that water can be sprayed on the farmland through the water spray component.

[0045] 3. At the same time, the hose reel 1 uses water pressure to generate a certain amount of mechanical kinetic energy through the work of the water turbine, gearbox and rotation system, and starts to rotate the reel. The rotation of the reel drives the end of the water supply pipe 2 located in the plot to reel back toward the end of the hose reel 1.

[0046] 4. Then, the reel is rotating, and the mobile bracket 3 and the mobile wheel 4 move at a set speed uniformly toward the hose reel 1, spraying water while moving, until the irrigation of the entire plot is completed.

[0047] 5. When the trolley moves to the position of the hose reel 1, the entire irrigation process is completed, and the connection between the water supply pipe 2 and the external water source is cut off. At this time, because the width of the water spray assembly is large, it is not convenient for storage and subsequent transportation. At this time, the controller on the hose reel 1 can be used in conjunction with the power supply of the internal power supply of the battery box 48 to start the two reversing mechanisms, and the power mechanism can be started within a few seconds after the reversing mechanism is started. During the process of the power mechanism, the reversing mechanism is always in operation.

[0048] 6. After the two reversing mechanisms are started at the same time, they will push their own connection ends in two opposite directions, and then when they are pushed to a certain extent, they can connect with the two transmission components respectively, and then the power mechanism will start.

[0049] 7. After the power mechanism is started, it remains stable and does not shake under the support of the support assembly, and at the same time, the output end of the power mechanism rotates together with the connected reversing mechanism and transmission assembly. After the transmission assembly rotates, the part of the water spray assembly extending on both sides of the mobile bracket 3 can be controlled to be recovered toward the middle position of the mobile bracket 3 until the recovery is completed. Then, the hose reel 1, water supply pipe 2 and mobile bracket 3 can be moved to the next plot through the transfer equipment and another irrigation can be carried out according to the above steps.

[0050] 8. When the extended part of the water spray assembly is about to be recovered to the middle position of the movable bracket 3, the opening and closing assembly of the extended part of the water spray assembly is connected with the opening and closing assemblies on the two support plates 6. Therefore, the shielding assembly can be rotated from the unfolded state to the shielding state through the opening and closing assembly, and when the shielding assembly is in the shielding state, the lower end of the water spray assembly is just shielded, thereby preventing the dust in the external environment from mixing with the residual water on the water spray assembly to form mud and cause the water spray assembly to be blocked.

[0051] 9. In addition, when the water spraying assembly is spraying water on the farmland, the farmland may be irregular, and there may be obstructions such as wind power towers, signal towers or high-voltage towers in the farmland. In order to avoid affecting the normal water spraying of the water spraying assembly, when moving to these positions, the operator can turn on one (only one side can be recovered when one is turned on) or two switching mechanisms on the controller at the reel 1, and then turn on the power mechanism, and then the overall width of the water spraying assembly can be appropriately shortened according to the obstruction situation, thereby avoiding collision with obstructions in the farmland.

[0052] Special mention should be made here:

[0053] 1. The agricultural irrigation machine of the present invention is similar in structure to the existing winch-type sprinkler.

[0054] 2. The water turbine, gearbox and rotation system mentioned above are all mature technologies in the existing hose reel 1, so they will not be described in detail here.

[0055] 3. The controller on the hose reel 1 and the power supply in the battery box 48 are also existing mature technologies and are not described in detail here. The battery box 48 is waterproof to prevent the sprayed water mist from damaging the batteries inside the battery box 48.

[0056] As a preferred solution of the present invention, the support assembly includes two support bars 19 and two raised plates 20, the lower ends of the two raised plates 20 are fixedly connected to the upper end of the movable bracket 3, the upper ends of the two raised plates 20 are respectively fixedly connected to the lower ends of the two support bars 19, the two support bars 19 are connected to the power mechanism, the two transmission assemblies are respectively connected to the two support bars 19, and the water spray assembly is connected to the two raised plates 20.

[0057] More specifically, by providing a support assembly, stable support can be provided to components such as the diversion assembly, the water spray assembly and the power mechanism.

[0058] In addition, in actual application, different farmlands may require different spraying heights. The two support bars 19 and the two raising plates 20 can be set to be retractable, so that the spraying height can be changed according to different crops in different farmlands, which has higher adaptability.

[0059] As a preferred solution of the present invention, the diversion assembly includes a four-way pipe 16 and three hoses 5, one end of the four-way pipe 16 is fixedly connected to the output end of the water supply pipe 2, the other three ends of the four-way pipe 16 are respectively fixedly connected to one end of the three hoses 5, and the other ends of the three hoses 5 are all connected to the water spray assembly.

[0060] More specifically, by providing a diverter assembly, a water source can be continuously provided between the hose reel 1 and the water spray assembly, and the diverter assembly can avoid uneven water spraying from several parts of the water spray assembly.

[0061] In addition, when it is necessary to connect the end of the water supply pipe 2 away from the hose reel 1 with the inside of the water spray assembly to achieve water supply, it only needs to be connected to one end of the four-way pipe 16 through a flange, and then connected to three hoses 5 through several other flanges, so that the water supplied by the water supply pipe 2 can be diverted to the water spray assembly through the three hoses 5 to spray the farmland.

[0062] It should be noted that the flange connection between the water supply pipe 2, the cross pipe 16 and the hose 5 is a mature technology, so it will not be described in detail here.

[0063] As a preferred solution of the present invention, the water spray assembly includes a fixed pipe 15, two extension pipes 7, four slide rails 22, a plurality of nozzles 8 and a plurality of valves 23. Three slide openings 41 are provided inside the two support plates 6. The outer wall of the middle part of the fixed pipe 15 is fixedly connected to the inner wall of the upper end of the two pad plates 20. The outer walls at both ends of the fixed pipe 15 are respectively fixedly connected to the inner wall of the middle slide opening 41 of the two support plates 6. The outer walls at both ends of the two extension pipes 7 are respectively slidably connected to the inner wall of the remaining two slide openings 41 of the two support plates 6. The plurality of nozzles 8 are evenly divided into three groups. The upper ends of the three groups of nozzles 8 are respectively fixedly connected to the bottom surfaces of the fixed pipe 15 and the two extension pipes 7. The valves 23 are evenly divided into two groups, and the two groups of valves 23 are respectively arranged in the two groups of nozzles 8 of the two extension tubes 7. The four slide rails 22 are evenly divided into two groups, and the side walls of the two groups of slide rails 22 are respectively fixedly connected to the side walls of the two extension tubes 7. The inner walls of a sliding opening 41 of the two support plates 6 away from each other are provided with a guide opening 42, and the outer walls of the two groups of slide rails 22 are respectively slidably connected to the inner walls of the two groups of guide openings 42, one end of one of the hoses 5 away from the four-way pipe 16 is fixedly connected to the middle part of the fixed pipe 15, and the ends of the other two hoses 5 away from the four-way pipe 16 are respectively fixedly connected to the ends of the two extension tubes 7 away from the guide openings 42, and the transmission assembly is connected to the two extension tubes 7.

[0064] More specifically, by providing a water spraying assembly, the water supplied from the diversion assembly can be accurately and evenly sprayed onto the farmland.

[0065] In addition, during installation, the fixed pipe 15 and the two extension pipes 7 are first connected to the three hoses 5 respectively, so that the hoses 5 can be connected to the water supply pipe 2, and then the water transported by the water supply pipe 2 can be sprayed to the farmland through the three groups of nozzles 8.

[0066] Furthermore, because valves 23 are provided inside the three groups of nozzles 8, in actual use, the farmland is relatively narrow and there is no need to use the fixed pipe 15 and the two extension pipes 7 at the same time, or there is no need for such dense nozzles 8 to spray water. In this case, before starting to spray water, a certain part of the valves 23 can be closed as needed, thereby stopping the water inside the water supply pipe 2 from spraying out from the closed nozzles 8.

[0067] It should be particularly noted here that: due to the action of the slide rail 22 and the guide opening 42, the extension tube 7 can only achieve lateral movement under the action of the transmission assembly, and one end will not be lifted up or rotated by itself, thereby ensuring that the nozzle 8 can always remain in a downward position; and a moving opening is left below the slide opening 41 on the support plate 6, so that when the extension tube 7 moves normally, the nozzle 8 will not collide with the support plate 6.

[0068] As a preferred embodiment of the present invention, the power mechanism includes a power motor 10, a transmission rod 13, a third gear 17, a center rod 25, a fourth gear 26 and a plurality of limit bars 27. The outer wall of the power motor 10 is fixedly connected to one side of the upper end of one of the support bars 19, the output shaft of the power motor 10 is fixedly connected to one end of the transmission rod 13, the other end of the transmission rod 13 passes through the third gear 17 and the two support bars 19, the outer wall of the transmission rod 13 is rotatably connected to the penetration of the two support bars 19, the outer wall of the transmission rod 13 is fixedly connected to the penetration of the third gear 17, the fourth gear 26 is sleeved and rotatably connected to the outer wall of the center rod 25, the two ends of the center rod 25 are respectively connected to the two reversing mechanisms and the two transmission components, the plurality of limit bars 27 are evenly divided into two groups, the two groups of limit bars 27 are respectively fixedly connected to the two sides of the fourth gear 26, the outer walls of the two groups of limit bars 27 are respectively connected to the two reversing mechanisms, the third gear 17 and the fourth gear 26 are meshed, and the power motor 10 is electrically connected to the battery in the battery box 48.

[0069] More specifically, by providing a power mechanism, electrical power can be provided when the two extension tubes 7 need to be retracted or extended without manual operation.

[0070] In addition, when it is necessary to control the extension tube 7 to be retracted or extended, it is only necessary to turn on the power motor 10 through the controller. The output shaft of the power motor 10 can rotate the transmission rod 13, and then the transmission rod 13 will rotate together with the No. 3 gear 17 connected to the surface, and then the No. 3 gear 17 will engage and rotate with the No. 4 gear 26. After the No. 4 gear 26 rotates, it will continue to rotate with a part of the reversing mechanism through two sets of limit bars 27, and then the reversing mechanism can be used to rotate the transmission assembly, and finally the extension tube 7 can be recovered or extended with the help of the transmission assembly.

[0071] It should be noted that: in actual application, the connection between the power motor 10, the third gear 17, the fourth gear 26 and the reversing mechanism, the transmission assembly and other components (i.e. Figure 7 A protective shell is set at the position shown in the figure, which not only reduces the probability of damage to the above components, but also makes the appearance more beautiful.

[0072] As a preferred embodiment of the present invention, the reversing mechanism includes an electromagnet 28, a connecting plate 29, a sliding rod 33 and an active spline 35. The upper end of the connecting plate 29 is sleeved and rotatably connected to the outer wall of the transmission rod 13, and the lower end of the connecting plate 29 is fixedly connected to the outer wall of the electromagnet 28. The electromagnet 28 is sleeved and slidably connected to the outer wall of the sliding rod 33. One end of the sliding rod 33 abuts against the side wall of the fourth gear 26, and the other end of the sliding rod 33 is fixedly connected to the side wall of the active spline 35. The other end of the active spline 35 is connected to the transmission assembly. The inner walls of the sliding rod 33 and the active spline 35 are slidably connected to the outer wall of the center rod 25. The inner walls of the sliding rod 33 and the active spline 35 are both provided with a plurality of sliding grooves 34. The inner walls of the plurality of sliding grooves 34 are respectively slidably connected to the outer walls of a group of limit strips 27, and the electromagnet 28 is electrically connected to the batteries in the battery box 48.

[0073] More specifically, by setting up a reversing mechanism, one transmission component can be selectively connected or two transmission components can be connected at the same time according to the needs of recovery and extension, so that one extension tube 7 can be recovered or two extension tubes 7 can be recovered at the same time according to the needs.

[0074] In addition, when the fourth gear 26 and the two sets of limit bars 27 rotate, due to the action of the limit bars 27, the slide bar 33 and the active spline 35 will rotate together, and the electromagnet 28 is in a state of relative rotation with the slide bar 33 because the upper end of the connecting plate 29 is connected to the transmission rod 13 and the slide bar 33 is sleeved on the outer wall of the center rod 25 (of course, the electromagnet 28 is in a stationary state at this time).

[0075] When there is no need to connect with the transmission assembly, the electromagnet 28 is in the on state, and the electromagnet 28 will continue to attract the active spline 35 (the active spline 35 is a magnetic material, such as metal iron) to its own direction. At this time, the magnetism of the electromagnet 28 is greater than the attraction of the transmission assembly, so that the active spline 35 and the transmission assembly are not in a connected state. When it is necessary to connect with one of the transmission assemblies, the electromagnet 28 only needs to be turned off. After the electromagnet 28 is turned off, the active spline 35 lacks pulling force, and the active spline 35 at this time will be attracted by the transmission assembly and move to the direction of the transmission assembly through the slide groove 34 and the limit bar 27, and the connection between the limit bar 27 and the transmission assembly can be achieved through the active spline 35. Therefore, after the subsequent power motor 10 is started, when the fourth gear 26 rotates, the transmission assembly can be rotated through the limit bar 27.

[0076] Special mention should be made here:

[0077] 1. The third gear 17 and the fourth gear 26 are both made of stainless steel that does not contain magnetic substances (of course, other non-magnetic materials are also possible). This can prevent the electromagnet 28 from affecting the meshing between the third gear 17 and the fourth gear 26 after being started, or from reversely affecting the other electromagnet 28 on the other side of the fourth gear 26.

[0078] 2. When only one transmission component needs to be connected, it is only necessary to turn on the electromagnet 28 in the corresponding direction. When the transmission components need to be connected, it is sufficient to turn on the two electromagnets 28 respectively. Similarly, because the two transmission components are connected through the two electromagnets 28, when one of the transmission components needs to recycle two meters and the other transmission component recycles one meter, one electromagnet 28 is turned on first, and then the other electromagnet 28 is turned on. This is only an example of an implementation method and is not specifically limited.

[0079] As a preferred embodiment of the present invention, the transmission assembly includes a connecting rod 18, an anti-drop rod 30, a common magnet 31, a passive spline 32, a No. 1 gear 11, a screw rod 12, a No. 2 gear 14 and a threaded ring 21. The No. 1 gear 11 is sleeved and fixedly connected to one end of the connecting rod 18, the No. 2 gear 14 is sleeved and fixedly connected to the outer wall of one end of the screw rod 12, the other end of the screw rod 12 passes through the support plate 6 and the threaded ring 21, the outer wall of the screw rod 12 is rotatably connected to the penetration point of the support plate 6, the outer wall of the screw rod 12 is threadedly connected to the inner wall of the threaded ring 21, and the lower end of the threaded ring 21 is connected to the The outer wall of the extension tube 7 away from the sliding mouth 41 is fixedly connected, the end of the connecting rod 18 away from the first gear 11 passes through the support plate 6 and is fixedly connected to one end of the anti-slip rod 30, and the outer wall of the connecting rod 18 is rotatably connected to the penetration point of the support plate 6, the other end of the anti-slip rod 30 is fixedly connected to one end of the common magnet 31, the other end of the common magnet 31 is fixedly connected to one side of the passive spline 32, the other side of the passive spline 32 matches the active spline 35, the outer wall of the end of the center rod 25 is slidably connected to the inner wall of the anti-slip rod 30, and the first gear 11 and the second gear 14 are meshed.

[0080] More specifically, by providing a transmission assembly, the power of the power mechanism and the reversing mechanism can be applied to the extension tube 7 through the transmission assembly, thereby realizing the recovery or outward extension of the extension tube 7.

[0081] In addition, when the electromagnet 28 is turned off, the active spline 35 lacks the strong pulling force of the electromagnet 28. At this time, the active spline 35 will automatically move to the direction of the ordinary magnet 31 through the slide groove 34 and the limit bar 27 under the attraction of the ordinary magnet 31, and in the process of moving, it will be misaligned and docked with the passive spline 32. Then, after the power motor 10 is started, the fourth gear 26 can rotate together with the active spline 35, the passive spline 32, the ordinary magnet 31, the anti-slip rod 30 and the connecting rod 18 through the limit bar 27.

[0082] After the connecting rod 18 rotates, the No. 1 gear 11 connected to the outside of the connecting rod 18 rotates together, and then meshes with the No. 2 gear 14 to rotate, and the No. 2 gear 14 rotates with the screw rod 12, so that the screw rod 12 thread can drive the threaded ring 21 and the extension tube 7 to achieve lateral movement in the sliding port 41 and the guide port 42.

[0083] It should be noted that the common magnet 31 is wrapped with a hard metal shell, so as to avoid the active spline 35 and the passive spline 32 from being damaged or easily causing the loss of parts when the active spline 35 collides with each other.

[0084] As a preferred embodiment of the present invention, the opening and closing assembly includes a No. 1 rack plate 24, a No. 5 gear 44, a No. 1 bevel gear 45 and an extension bar 47. One end of the No. 1 rack plate 24 is fixedly connected to the outer wall of the extension tube 7 away from the threaded ring 21, one end of the extension bar 47 is fixedly connected to the side of the support plate 6 away from the movable bracket 3, and the other end of the extension bar 47 is sleeved and rotatably connected to the rotating shaft of the No. 5 gear 44. The side of the No. 5 gear 44 away from the rotating shaft is fixedly connected to the upper surface of the No. 1 bevel gear 45, the No. 1 rack plate 24 is meshed with the No. 5 gear 44, and the No. 1 bevel gear 45 is connected to the shielding assembly.

[0085] More specifically, by setting up an opening and closing component, the shielding component can be automatically opened when the extension tube 7 moves outward from the inside of the mobile bracket 3 to prevent the shielding component from obstructing the normal water spraying of the nozzle 8; the shielding component can also be automatically closed when the extension tube 7 returns to the inside of the mobile bracket 3, thereby preventing dust in the external environment from mixing with the remaining water on the nozzle 8 to form mud, causing the nozzle 8 to be blocked.

[0086] In addition, when the extension tube 7 is located inside the mobile bracket 3, the shielding assembly is horizontally located below the nozzle 8 and shields the nozzle of the nozzle 8; and when the extension tube 7 extends to one side from the mobile bracket 3, the rack plate 24 installed at the end of the extension tube 7 will mesh with the gear 44 No. 5 during the movement, and then the gear 44 No. 5 rotates to rotate with the bevel gear 45 No. 1, and then the bevel gear 45 can rotate with the shielding assembly, and then the shielding assembly can be rotated to the unfolded state (at this time, the shielding assembly will not hinder the fixed tube 15 and the nozzles 8 on the two extension tubes 7), and then the extension tube 7 continues to move, the rack plate 24 No. 1 is disengaged from the gear 44 No. 5, and then the extension tube 7 continues to move until it stops after moving to the set length;

[0087] Similarly, when the extension tube 7 returns, the No. 1 rack plate 24 at the front end of the extension tube 7 will mesh with the No. 5 gear 44 again, and during the meshing process, because the No. 1 rack plate 24 continues to move, the No. 5 gear 44 can be rotated in the opposite direction, so that the unfolded shielding assembly can be returned to its original position again, and then the No. 1 rack plate 24 and the No. 5 gear 44 are always in a meshing state, so the rotation of the shielding assembly can be restricted, thereby avoiding the situation where the shielding effect is affected.

[0088] As a preferred solution of the present invention, the shielding assembly includes a shielding plate 9, a second bevel gear 46, two support blocks 36, two rotating rods 37, two connecting columns 38 and four magnet plates 40. A plurality of openings 39 are provided on one side of the shielding plate 9. The inner walls of the plurality of openings 39 match and are slidably connected to the outer walls of the padding plate 20 and the hose 5. The two ends of the shielding plate 9 away from the openings 39 are respectively fixedly connected to the lower ends of the two connecting columns 38. The upper ends of the two connecting columns 38 are respectively sleeved and fixedly connected to the outer walls of one end of the two rotating rods 37. The other ends of the two rotating rods 37 pass through the two supporting blocks 36 respectively and are rotatably connected to the inner walls of the two supporting blocks 36. The other ends of the two supporting blocks 36 are fixedly connected to the side walls of the two supporting plates 6 respectively. One end of one of the rotating rods 37 passes through the supporting blocks 36 and is fixedly connected to one end of the No. 2 bevel gear 46. The No. 1 bevel gear 45 is meshed with the No. 2 bevel gear 46. The four magnet plates 40 are fixedly connected to the two connecting columns 38 and the side walls of the two supporting plates 6 respectively, and the connecting columns 38 and the two magnet plates 40 on the support plates 6 attract each other.

[0089] More specifically, by providing a shielding component, the three groups of nozzles 8 on the fixed tube 15 and the two extension tubes 7 can be shielded, thereby reducing the probability of clogging of the nozzles 8.

[0090] In addition, when the No. 1 bevel gear 45 rotates, it can engage and drive the No. 2 bevel gear 46 to rotate, and then the No. 2 bevel gear 46 drives the rotating rod 37 connected to it to rotate inside the support block 36, and this rotating rod 37 will drive the connecting column 38 to rotate together, and then cooperate with the baffle plate 9 to drive the connecting column 38 and the rotating rod 37 at the other end of the baffle plate 9 to rotate inside the support block 36, thereby realizing the rotation of the baffle plate 9.

[0091] When the shielding plate 9 rotates to the unfolded state, the magnet plate 40 on the connecting column 38 is attracted to the magnet plate 40 on the supporting plate 6, thereby limiting the position of the shielding plate 9 so that the shielding plate 9 will not rotate back by itself, and at the same time, it can also limit the positions of the No. 2 bevel gear 46, the No. 1 bevel gear 45 and the No. 5 gear 44, so that when the No. 1 rack plate 24 returns subsequently, it can continue to be in a meshing state.

[0092] When the No. 1 rack plate 24 returns, the meshing force between the No. 1 rack plate 24, the No. 5 gear 44, the No. 1 bevel gear 45 and the No. 2 bevel gear 46 will forcibly separate the magnetism between the connecting column 38 and the magnet plate 40 between the support plate 6, so that the shielding plate 9 can be turned back to the bottom of the nozzle 8 for shielding.

[0093] As a preferred solution of the present invention, a No. 2 rack plate 43 is fixedly connected to the adjacent sides of the two support plates 6, and teeth are provided on the handwheels of several valves 23 on the two extension tubes 7, and the two No. 2 rack plates 43 are respectively engaged with the teeth on the two groups of valves 23.

[0094] More specifically, by providing the second rack plate 43 and teeth on the hand wheel of the valve 23, the valve 23 in the nozzle 8 can be automatically opened and closed when the extension tube 7 moves along the sliding opening 41 and the guide opening 42, thereby eliminating the need for manual operation.

[0095] Furthermore, when the extension tube 7 encounters an obstacle during spraying and needs to be temporarily shortened to avoid the obstacle, this part of the nozzle 8 can also be temporarily closed during the recovery process of the extension tube 7 to achieve the purpose of saving water resources.

[0096] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
