Description

Technical Field

[0001] This invention belongs to the technical field of livestock equipment, specifically relating to a livestock transfer and weighing device. Background Technology

[0002] When livestock farming transitions to the market, it is necessary to transfer the livestock from the breeding shed to the transport vehicle. This is where the transfer vehicle comes in. First, the livestock is driven from the breeding shed to the transfer vehicle, weighed using the scale on the transfer vehicle, and then driven from the transfer vehicle to the transport vehicle.

[0003] Currently, livestock transport vehicles typically use weighing devices similar to weighbridges. However, because it's difficult to ensure that livestock remain centered on the weighing device when being driven onto the vehicle, weighing errors are significant. Furthermore, the rough movements of livestock before they settle down cause considerable impact on the weighing panel, making it prone to damage and malfunction. These weighing devices are complex in structure, and repairs are time-consuming, labor-intensive, and costly. Given these factors, there is an urgent need to improve the weighing accuracy during livestock transport and reduce the failure rate and maintenance costs of the weighing devices. Summary of the Invention

[0004] This invention provides a livestock transfer weighing device, which aims to reduce weighing errors during livestock transfer, and lower the failure rate and maintenance costs of the livestock transfer weighing device.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A livestock transfer and weighing device is provided, comprising a transfer vehicle body, two cages, two pulleys, a lifting rope, and a digital display controller; fences are provided on both sides of the transfer vehicle body, and a top frame is connected to the top of the two fences; openable door panels are provided at the front and rear ends of the transfer vehicle body, and a lifting partition is provided between the two door panels; two cages are located inside the transfer vehicle body, respectively on the front and rear sides of the lifting partition, with the front and rear ends of the cages open, forming a circumferentially enclosed weighing space based on the closed door panels and the lowered lifting partition; two pulleys are respectively connected to the top frame and are located directly above the two cages; one end of the lifting rope is connected to the top center of one cage, and the other end passes around the two pulleys and is connected to the top center of the other cage; a tension sensor is connected to the lifting rope between the two pulleys; the digital display controller is located on the transfer vehicle body and electrically connected to the tension sensor, used to receive and display the detection value of the tension sensor;

[0006] The suspension rope has a limit block on each side of the tension sensor, and the top frame has two stops spaced at the front and back. The two stops are located between the two limit blocks and abut against the two limit blocks respectively. The stops have holes suitable for the suspension rope to pass through.

[0007] In one possible implementation, two drive plates are slidably connected to both sides of the cage. Each drive plate has an upwardly extending drive rod in the middle. The top ends of the two drive rods bend towards each other. The bent extension ends of the two drive rods are spaced apart in the front-back direction and have racks on the walls that are close to each other. The top of the cage has a rotary drive component that is electrically connected to a digital display controller and has a gear sleeved at its output end. The radial sides of the gear mesh with the two racks respectively.

[0008] In some embodiments, two clearance areas are distributed at intervals on the bottom plate of the transfer vehicle body, the bottoms of the two cages are respectively embedded in the two clearance areas, and there is a circumferential gap between the bottom of the cage and the clearance area.

[0009] For example, a limiting sleeve is provided below the bottom plate of the transfer vehicle body, and a positioning sleeve extending downward is provided at the center of the bottom end of the cage. The positioning sleeve passes through the limiting sleeve, and there is an movable gap between the positioning sleeve and the limiting sleeve. The positioning sleeve is provided with a tensioning component, which is electrically connected to the digital display controller. The tensioning component has a tensioned state in which it expands outward to circumferentially press against the inner peripheral wall of the limiting sleeve, and also has a relaxed state in which it contracts inward to the positioning sleeve.

[0010] For example, the positioning sleeve has multiple mounting slots spaced circumferentially. The tensioning assembly includes multiple swing arms, a push drive, and an elastic element. Each swing arm is connected to a corresponding mounting slot, with its middle section rotatably connected to the side walls of the mounting slot. The first end extends upwards, and the second end extends into the positioning sleeve. In the tensioned state, the first end of each swing arm abuts against the inner circumferential wall of the positioning sleeve. In the relaxed state, the first end of each swing arm swings into its corresponding mounting slot. The push drive is fixedly connected to the bottom of the positioning sleeve and electrically connected to a digital display controller. The telescopic end of the push drive extends into the positioning sleeve and abuts against the second end of each swing arm. The telescopic end of the push drive is used to push the second end of each swing arm upwards to form a tensioned state. The elastic element is located inside the positioning sleeve, between the top wall of the positioning sleeve and the second end of each swing arm. The elastic element is used to elastically push the second end of each swing arm downwards when the push drive retracts to form a relaxed state.

[0011] In one possible implementation, a lifting drive assembly is provided on the top frame, which is electrically connected to a digital display controller, and the output end of the lifting drive assembly is connected to the lifting partition; two vertical guide rails are provided between two cages inside the transfer vehicle body, and the two vertical guide rails are respectively attached and fixed to two fences, and the two sides of the lifting partition are respectively slidably connected to the two vertical guide rails.

[0012] For example, the lifting drive assembly includes two first guide wheels, two second guide wheels, a telescopic traction member, and a traction rope; wherein, the two first guide wheels are fixedly connected to the top frame near two vertical guide rails; the two second guide wheels are horizontally rotatably connected to the top frame and are both located in the middle of the two first guide wheels; the telescopic traction member is horizontally connected to the top frame and electrically connected to the digital display controller, with the telescopic end of the telescopic traction member facing the second guide wheel; the middle part of the traction rope is connected to the telescopic end of the telescopic traction member, one end of which passes through one of the second guide wheels and one of the first guide wheels in sequence and extends downward to connect with the top side of the lifting partition, and the other end passes through the other second guide wheel and the other first guide wheel in sequence and extends downward to connect with the top other side of the lifting partition.

[0013] For example, two vertical guide rails are provided with vertically extending guide grooves, and rollers suitable for rolling the side walls of the guide grooves are provided on both sides of the lifting partition.

[0014] In some embodiments, one edge of the door panel is rotatably connected to the bottom edge of the transfer vehicle body, and the bottom of the transfer vehicle body is provided with a flip drive assembly for driving the door panel to flip to open or close. The flip drive assembly is electrically connected to the digital display controller.

[0015] For example, the tilting drive assembly includes a connecting rod and a telescopic drive component; one end of the connecting rod is fixedly connected to the door panel, and the other end extends obliquely downward toward the bottom plate of the transfer vehicle body, with the connecting rod and the surface of the door panel forming an angle; one end of the telescopic drive component is hinged to the part below the bottom plate of the transfer vehicle body, and the other end is hinged to the extended end of the connecting rod; wherein, the door panel obtains different opening angles based on the different telescopic lengths of the telescopic drive component, and the door panel in the open state is used to form a transition plate suitable for livestock to walk into or out of the weighing space.

[0016] The beneficial effects of the livestock transfer and weighing device provided by this invention are as follows: Compared with the prior art, the livestock transfer and weighing device of this invention can obtain a tension detection value once when the livestock passes through the transfer vehicle and enters the two weighing spaces in sequence, thereby obtaining two weighing data of the livestock. If the difference between the two weighing data is within the error range, the weighing data can be identified as the weight of the livestock. If the difference between the two weighing data exceeds the error range, the livestock is re-weighed in the two cages until the required weighing data is obtained. Because the weighing method uses cage traction, the livestock can be weighed again. The method is unaffected by the position of the livestock, and by setting up two cages at the front and back, it can perform two weighings and multiple re-weighings, thus improving the weighing accuracy of the livestock. In addition, since the two cages are connected by a rope and are based on two sets of limit blocks and stops for positioning, the same tension sensor can be used to weigh the livestock entering the two weighing spaces. Not only is the structure simple, but the cage structure itself is a rigid structure that is not easy to damage, so the failure rate is low. The only vulnerable parts are the tension sensor and the rope, which makes maintenance simple and convenient and the maintenance cost low. Attached Figure Description

In the description of the present invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] Please refer to the following: Figures 1 to 8The livestock transfer and weighing device provided by the present invention will now be described. The livestock transfer and weighing device includes a transfer vehicle body 10, two cages 20, two pulleys 30, a suspension rope 40, and a digital display controller 60. The transfer vehicle body 10 has fences 11 on both sides, and a top frame 12 is connected to the top of the two fences 11. Openable door panels 13 are provided at the front and rear ends of the transfer vehicle body 10, and a lifting partition 14 is located between the two door panels 13. The two cages 20 are located inside the transfer vehicle body 10 and are respectively located on the front and rear sides of the lifting partition 14. The front and rear ends of the cages 20 are open, and the cages 20 form a circumferentially enclosed weighing space based on the closed door panels 13 and the lowered lifting partition 14. The two pulleys 30 are respectively connected to the top frame 12 and are respectively located on the front and rear sides of the lifting partition 14. The suspension rope 40 is located directly above the cage 20. One end of the rope is connected to the top center of one of the cages 20, and the other end passes around two pulleys 30 and is connected to the top center of the other cage 20. A tension sensor 50 is connected to the rope 40 between the two pulleys 30. A digital display controller 60 is located on the transfer vehicle body 10 and is electrically connected to the tension sensor 50 to receive and display the detection value of the tension sensor 50. A limiting block 41 is provided on the rope 40 on both sides of the tension sensor 50. Two stops 121 are provided on the top frame 12 at a distance from front to back. The two stops 121 are located between the two limiting blocks 41 and abut against the two limiting blocks 41 from front to back. The stops 121 are provided with holes suitable for the rope 40 to pass through.

[0029] First, it should be noted that, for ease of operation and improved efficiency, the opening and closing of the two door panels 13 and the lifting action of the lifting partition 14 in this embodiment are all electrically driven and controlled by the digital display controller 60. Based on this, the working principle of the livestock transfer and weighing device provided in this embodiment is as follows:

[0030] When livestock are transferred from the breeding shed to the transport vehicle, the transport vehicle 10 is parked between the shed's enclosure and the transport vehicle's door. First, the front door panel 13 is opened, at which point the rear door panel 13 is closed and the middle partition is lowered. Then, the livestock are driven from the breeding shed into the cage 20 near the front. The front door panel 13 is then closed so that the livestock remain in the weighing space at the front. At this time, the tension of the suspension rope 40 increases due to the increased weight of the cage 20 at the front. Since the limiting block 41 and the stop block 121, which are far from the cage 20 at the front, are in contact, the detection value of the tension sensor 50 is the total weight of the cage 20 at the front and the livestock. Since the weight of the cage 20 is constant, the total weight minus the weight of the cage 20 is used to obtain the weighing value of the livestock.

[0031] After the livestock is weighed in the front cage 20, the middle partition is raised, and the livestock is driven into the rear cage 20. The middle partition is then lowered, and the livestock will remain in the rear weighing space. At this time, the tension of the suspension rope 40 increases in the opposite direction due to the increased weight of the rear cage 20. Since the limiting block 41 and the stop block 121, which are far from the rear cage 20, are in contact, the detection value of the tension sensor 50 is the total weight of the rear cage 20 and the livestock. Since the weight of the cage 20 is constant, the total weight minus the weight of the cage 20 can be used to obtain the weighing value of the livestock again.

[0032] Comparing two weighing values, under normal circumstances, they should be equal or within an acceptable range of difference. In this case, the weighing value is accurate, and the rear door 13 can be opened directly to drive the livestock onto the transport vehicle. If the difference between the two weighing values ​​is large, it indicates that the weighing value is inaccurate. Since it is impossible to determine which of the two weighing values ​​is inaccurate, simply raise the lifting partition 14 again, drive the livestock back into the front cage 20, lower the lifting partition 14, and then re-weigh in the front weighing space. Compare the re-weighed value with the first two weighing values. If two of the three weighing values ​​are equal or... If the two weighing values ​​are close to equal, then the two weighing values ​​can be determined to be the weight of the livestock. At this time, simply raise the lifting partition 14 and open the rear door 13 to drive the livestock onto the transport vehicle. If the three weighing values ​​are different and the difference is large, raise the lifting partition 14 and drive the livestock into the rear cage 20 for a second weighing to obtain a fourth weighing value. If two identical weighing values ​​are obtained at this time, the weight of the livestock can be determined. If all four weighing values ​​are different and the difference is large, it may be due to a fault in the tension sensor 50 or a jam between the hoisting rope 40 and the pulley 30. Repair and troubleshooting are required before weighing again.

[0033] Compared with the prior art, the livestock transfer and weighing device provided in this embodiment can obtain a tension detection value by the tension sensor 50 when the livestock passes through the transfer vehicle 10 and enters the two weighing spaces in sequence, thereby obtaining two weighing data of the livestock. If the difference between the two weighing data is within the error range, the weighing data can be identified as the weight of the livestock. If the difference between the two weighing data exceeds the error range, the livestock is re-weighed in the two cages 20 until the required weighing data is obtained. Since the weighing method using cages 20 is not affected by the position of the livestock, and the... By setting up two cages 20, two weighings and multiple re-weighings can be performed, thus improving the weighing accuracy of livestock. In addition, since the two cages 20 are connected by a rope 40 and are positioned based on two sets of limit blocks 41 and stop blocks 121 respectively, the same tension sensor 50 can be used to weigh livestock entering the two weighing spaces. Not only is the structure simple, but the cage 20 itself is a rigid structure that is not easy to damage, so the failure rate is low. The only vulnerable parts are the tension sensor 50 and the rope 40, which makes maintenance simple and convenient and the maintenance cost low.

[0034] It should be noted that, in this embodiment, see Figure 5 The cage 20 is slidably connected to two sides of the cage 20. The middle of each of the two cages 21 is provided with an upwardly extending drive rod 211. The top ends of the two drive rods 211 are bent and extended toward each other. The bent and extended ends of the two drive rods 211 are spaced apart in the front-back direction and are close to each other. Both of the walls are provided with racks 212. The top of the cage 20 is provided with a rotary drive component 22. The rotary drive component 22 is electrically connected to the digital display controller 60 and the output end is sleeved with a gear 221. The radial sides of the gear 221 are respectively engaged with the two racks 212.

[0035] The output end of the rotating drive component 22 drives the gear 221 to rotate, which in turn drives the two racks 212 to move in opposite directions. This, in turn, drives the two drive rods 211 to move the two drive plates 21 closer to each other or further apart. When driving livestock into the cage 20, the two drive plates 21 are opened to the maximum extent to facilitate the entry of livestock. After the livestock enter the weighing space, the process of the two drive plates 21 moving closer to each other drives the livestock to the middle area of ​​the weighing space. This can avoid or reduce the shaking of the cage 20 during the weighing process and improve the weighing accuracy.

[0036] Specifically, in this embodiment, the bent extension ends of both drive rods 211 are provided with sliding holes suitable for passing through each other to form a sliding fit. The sliding fit between the drive rods 211 and the sliding holes can improve the structural strength between the two drive rods 211, and at the same time improve the meshing transmission stability between the gear 221 and the two racks 212.

[0037] For some possible implementations, please refer to [link / reference]. Figure 2 and Figure 4 The bottom plate of the transport vehicle 10 has two clearance areas spaced at intervals. The bottoms of the two cages 20 are respectively embedded in the two clearance areas, and there is a circumferential gap 101 between the bottom of the cage 20 and the clearance area. By setting the clearance areas, the bottom wall of the cage 20 is embedded, which can constrain the cage 20 and reduce the swaying amplitude of the cage 20 before the livestock enter the cage 20 and stabilize. At the same time, the circumferential gap 101 can ensure that the cage 20 is suspended after it stabilizes, thereby avoiding contact between the cage 20 and the transport vehicle 10 and affecting the weighing accuracy.

[0038] Based on the above, see Figure 2 and Figure 3 In this embodiment, a limiting sleeve 15 is provided below the bottom plate of the transfer vehicle body 10, and a positioning sleeve 23 extending downward is provided at the bottom center of the cage 20. The positioning sleeve 23 passes through the limiting sleeve 15, and there is an movable gap 102 between the positioning sleeve 23 and the limiting sleeve 15. The positioning sleeve 23 is provided with a tensioning component 24, which is electrically connected to the digital display controller 60. The tensioning component 24 has a tensioned state in which it expands outward to circumferentially press against the inner peripheral wall of the limiting sleeve 15, and also has a relaxed state in which it contracts inward into the positioning sleeve 23.

[0039] Before the livestock are stabilized in the cage 20, the tensioning component 24 in the tensioned state forms a fixed connection between the positioning sleeve 23 and the limiting sleeve 15, thereby preventing the cage 20 from shaking and colliding with the transport vehicle 10. After the livestock are stabilized, the tensioning component 24 is switched to the relaxed state. At this time, the cage 20 is restored to the suspended state by the movable gap 102 between the positioning sleeve 23 and the limiting sleeve 15, thereby obtaining an accurate weighing value.

[0040] It should be explained that when the tensioning component 24 tightens the movable gap 102 between the positioning sleeve 23 and the limiting sleeve 15, after the livestock enters the weighing space, the two driving plates 21 can be used to bring the livestock closer together to stabilize them in the middle area of ​​the weighing space. Then the tensioning component 24 is loosened, which can ensure the stability of the cage 20 in the suspended state, which not only saves time but also improves the weighing accuracy.

[0041] Specifically, see Figure 3In this embodiment, the positioning sleeve 23 has multiple mounting slots 231 spaced apart along its circumference. The tensioning assembly 24 includes multiple swing arms 241, a pushing drive component 242, and an elastic component 243. Each swing arm 241 is connected to a corresponding mounting slot 231. The middle part of each swing arm 241 is rotatably connected to the two side walls of the mounting slot 231. The first end extends upwards, and the second end extends into the positioning sleeve 23. In the tensioned state, the first end of each swing arm 241 abuts against the inner circumferential wall of the limiting sleeve 15. In the relaxed state, the first end of each swing arm 241 swings to the corresponding mounting slot 231. Inside 31; the push drive 242 is fixedly connected to the bottom end of the positioning sleeve 23 and electrically connected to the digital display controller 60. The telescopic end of the push drive 242 extends into the positioning sleeve 23 and abuts against the second end of each swing arm 241. The telescopic end of the push drive 242 is used to push the second end of each swing arm 241 upward to form a tensioned state. The elastic member 243 is provided inside the positioning sleeve 23 and is located between the top wall of the positioning sleeve 23 and the second end of each swing arm 241. The elastic member 243 is used to elastically push the second end of each swing arm 241 downward when the push drive 242 retracts to form a relaxed state.

[0042] The elastic element 243 can be a spring or a disc spring, and the push drive element 242 can be a cylinder or a hydraulic cylinder with a solenoid valve. When the telescopic end of the push drive element 242 extends, it pushes the second end of each swing arm 241 upward, so that each swing arm 241 swings synchronously until its first end presses against the inner circumferential wall of the limiting sleeve 15, so that each swing arm 241 forms a circumferentially tensioned and fixed state with the limiting sleeve 15. When the push drive element 242 retracts, its telescopic end moves downward, and the second end of each swing arm 241 is subjected to the downward elastic push force of the elastic element 243, so that each swing arm 241 swings synchronously back to its first end and retracts into the corresponding mounting groove 231. At this time, the positioning sleeve 23 and the limiting sleeve 15 lose their constraint relationship, so that the cage 20 is in a completely suspended state based on the activity gap 102 and the circumferential gap 101.

[0043] In one possible implementation, please participate. Figure 1 and Figure 2 The top frame 12 is equipped with a lifting drive assembly 122, which is electrically connected to the digital display controller 60, and the output end of the lifting drive assembly 122 is connected to the lifting partition 14. Inside the transfer vehicle body 10, there are two vertical guide rails 16 between the two cages 20. The two vertical guide rails 16 are respectively attached and fixed to the two fences 11, and the two sides of the lifting partition 14 are respectively slidably connected to the two vertical guide rails 16.

[0044] The lifting drive assembly 122 can be a gear 221 and rack 212 driven by a motor, or it can be a winch pulling the lifting barrier 14. The lifting drive assembly 122 drives the lifting barrier 14 to rise or fall. At the same time, the two sides of the lifting barrier 14 form a sliding engagement with the two vertical guide rails 16, thereby improving the connection stability and lifting smoothness of the lifting barrier 14.

[0045] As one specific embodiment of the above-mentioned lifting drive assembly 122, please refer to Figure 1 The lifting drive assembly 122 includes two first guide wheels 1221, two second guide wheels 1222, a telescopic traction member 1223, and a traction rope 1224. The two first guide wheels 1221 are fixedly connected to the top frame 12 near the two vertical guide rails 16. The two second guide wheels 1222 are horizontally rotatably connected to the top frame 12, and are both located in the middle of the two first guide wheels 1221. The telescopic traction member 1223 is horizontally connected to the top frame 12 and electrically connected to the digital display controller 60, with the telescopic end of the telescopic traction member 1223 facing the second guide wheels 1222. The middle part of the traction rope 1224 is connected to the telescopic end of the telescopic traction member 1223. One end passes sequentially around one of the second guide wheels 1222 and one of the first guide wheels 1221, extends downward, and connects to one side of the top of the lifting partition 14. The other end passes sequentially around the other second guide wheel 1222 and the other first guide wheel 1221, extends downward, and connects to the other side of the top of the lifting partition 14.

[0046] By utilizing the guiding and redirecting functions of two first guide wheels 1221 and two second guide wheels 1222, the two ends of the same traction rope 1224 are connected to the top walls on both sides of the lifting barrier 14, while the middle of the traction rope 1224 is connected to the telescopic end of the telescopic traction component 1223. This not only enables the horizontal installation of the telescopic traction component 1223 on the top frame 12, reducing the space occupied above the top frame 12 and avoiding limitations on the applicable environment due to excessive height, but also allows the use of a simple and efficient cylinder or hydraulic cylinder (with a solenoid valve) as the telescopic traction component 1223, thereby reducing costs. When the telescopic traction component 1223 extends, the downward length of the two ends of the traction rope 1224 increases, causing the lifting barrier 14 to descend under its own weight. When the telescopic end of the telescopic traction component 1223 retracts, it simultaneously generates an upward pulling force on the two ends of the traction rope 1224, thereby driving the lifting barrier 14 to rise. The lifting action is smooth and rapid.

[0047] It should be noted that, as Figure 6As shown, in this embodiment, vertically extending guide grooves 161 are provided within the two vertical guide rails 16, and rollers 141 suitable for rolling the side walls of the guide grooves 161 are provided on both sides of the lifting partition 14. By setting the rollers 141 to form front and rear rolling supports between the rollers 141 and the side walls of the guide grooves 161, not only can the connection stability of the lifting partition 14 be improved, but the lifting resistance of the lifting partition 14 can also be reduced, and the smoothness of the lifting action can be improved.

[0048] For some possible implementations, please refer to [link / reference]. Figure 7 One edge of the door panel 13 is rotatably connected to the edge of the bottom plate of the transport vehicle body 10. The bottom of the transport vehicle body 10 is provided with a flipping drive assembly 17 for driving the door panel 13 to flip open or close. The flipping drive assembly 17 is electrically connected to the digital display controller 60. The door panel 13 can be flipped up and down to open or close by rotating it to the edge of the bottom plate of the transport vehicle body 10. In particular, after the door panel 13 is opened, it can serve as a transition board for livestock to step on when getting on or off the vehicle, thereby reducing the difficulty of livestock getting on and off the vehicle. The method of using the flipping drive assembly 17 to realize the electric control of the opening and closing of the door panel 13 not only saves labor but also helps to improve the efficiency of livestock transportation.

[0049] For example, see Figure 7 The flipping drive assembly 17 includes a connecting rod 171 and a telescopic drive member 172. One end of the connecting rod 171 is fixedly connected to the door panel 13, and the other end extends obliquely downward toward the bottom plate of the transfer vehicle body 10. The connecting rod 171 is set at an angle to the surface of the door panel 13. One end of the telescopic drive member 172 is hinged to the part below the bottom plate of the transfer vehicle body 10, and the other end is hinged to the extended end of the connecting rod 171. The door panel 13 obtains different opening angles based on the different telescopic lengths of the telescopic drive member 172, and the door panel 13 in the open state is used to form a transition plate suitable for livestock to walk into or out of the weighing space.

[0050] The telescopic drive component 172 can be a hydraulic cylinder or a pneumatic cylinder with a solenoid valve. The telescopic drive component 172 pushes and pulls the connecting rod 171 to transmit a flipping force to the door panel 13, thereby realizing the opening or closing of the door panel 13. By controlling the extension length of the telescopic drive component 172, the opening angle of the door panel 13 can be controlled, so that the door panel 13 can tilt downward at the optimal angle to connect with the ground or tilt upward to connect with the floor of the transport vehicle, thus serving as a transition plate, which facilitates the entry and exit of livestock into and out of the transport vehicle 10 and reduces the difficulty of livestock transport.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
