Description

Technical Field

[0001] This invention relates to the field of mineral loading technology, specifically to an automatic conveying and loading device for mining operations. Background Technology

[0002] Minerals refer to ores, minerals or mixtures thereof that contain a certain mineral in nature and can be mined, refined and utilized. Minerals are usually formed from rocks or sediments in the earth's crust that are rich in a certain mineral. They can be used to produce metals, building materials and chemical raw materials, etc. Nowadays, the transportation and loading of minerals are usually done by loading equipment.

[0003] According to the Chinese Patent Publication No. CN117342290B, an automatic loading device for mining operations involves a material feeding frame moving to the next discharge port, an automatic lifting frame descending, and a baffle opening to load material at the next location. A feeding conveyor transports the ore to a storage bin. Positive and negative spiral blades ensure even distribution of the ore. This eliminates the need for the mine car driver to repeatedly control the car's movement for loading, resulting in automatic and uniform loading, reduced manual labor, and high loading efficiency. However, there are still shortcomings. Because there is a gap between two adjacent discharge ports, the automatic lifting frame swings left and right to feed the ore, preventing continuous feeding. The ore fed from each discharge port exhibits a cone-shaped pattern, leading to poor uniformity after loading. Furthermore, the ore tends to accumulate in the middle of the truck bed after exiting the automatic lifting frame. Summary of the Invention

[0004] To address these issues, the present invention provides an automated conveying and loading device for mining operations in a mining area.

[0005] The present invention provides the following technical solution: an automatic conveying and loading device for mining in a mining area, including a conveyor, a fixed frame at one end of the conveyor, and a loading and feeding component at the top of the fixed frame;

[0006] The loading and feeding component includes two side panels fixedly installed on the top of a fixed frame. The two side panels are arranged front to back.

[0009] As a preferred embodiment of the present invention, a spring support is fixedly installed on the outer wall of each slide rod. The spring support is located at the bottom of the slider, and a first spring is sleeved around the periphery of each slide rod. The first spring is fixedly installed between the top of the spring support and the bottom of the slider. A right-angle bracket is fixedly installed on the top of each slide rod. A guide hole is opened through the side of the right-angle bracket near the guide block. A guide rod is slidably installed inside the guide hole. An end cap is fixedly installed at the end of the guide rod away from the guide block. A second spring is sleeved around the periphery of the guide rod. The second spring is fixedly installed between the side of the right-angle bracket and the end cap.

[0010] As a preferred embodiment of the present invention, the left and right sides of the guide block are provided with guide grooves, the guide grooves are located at the top of the slide groove, and the specifications of the guide grooves are adapted to the specifications of the guide rods. Two inclined grooves are provided at the top of the guide block near the feeding square tube, and the inclined grooves are connected to the interior of the guide grooves. The top angle of the end of the guide block away from the feeding square tube is set at a 45° angle.

[0011] As a preferred embodiment of the present invention, the connecting beam is internally equipped with a loading and compaction component. The loading and compaction component includes a compaction rod slidably installed inside the connecting beam. The compaction rod movably passes through the top and bottom of the connecting beam. A compaction plate is fixedly installed at the bottom of the compaction rod. The compaction plate is located inside the scraper. A pressure head is fixedly installed at the top of the compaction rod. The pressure head is located between two sliding rods. A strip groove is opened through the side of the pressure head near the feeding square tube. A driven shaft is rotatably installed at the front and rear of the feeding square tube. The driven shaft is located at the bottom of the reciprocating screw.

The outer wall of the eccentric rod is slidably connected to the inside of the strip groove.

[0012] As a preferred embodiment of the present invention, a driven gear is fixedly installed on the outer wall of the driven shaft, a driving gear is fixedly installed on the outer wall of the reciprocating screw, the bottom of the driving gear meshes with the top of the driven gear, and a gear housing is fixedly installed on the rear wall of the feeding square tube, the gear housing being located around the driving gear and the driven gear.

[0013] As a preferred embodiment of the present invention, a bearing bracket is fixedly installed at the bottom of the guide block away from the feeding square tube, and the bearing bracket is rotatably connected to the reciprocating lead screw and the driven shaft through bearings.

[0014] As a preferred embodiment of the present invention, the left and right sides of the funnel are provided with relief grooves, which are located on the bottom periphery of the second guide groove tile.

[0015] As a preferred embodiment of the present invention, two reinforcing rods distributed on the left and right are fixedly installed between the upper part of the two side panels that are close to each other.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In this invention, rodless cylinders swing left and right along two smooth rods under hydraulic pressure. The left and right movement of the two rodless cylinders drives the feeding square tube, corrugated telescopic steel sleeve, and funnel to swing left and right together. When the funnel moves to the left, a second guiding groove tile located at the left end of the funnel slides into the interior of a telescopic groove connected to it, while a second guiding groove tile located at the right end of the funnel slides outward along a telescopic groove connected to it. When the funnel slides to the right, the opposite occurs. This ensures that during the left and right swing of the funnel, the two first and second guiding groove tiles always have a guiding effect on the ore, allowing it to smoothly enter the interior of the funnel. Thus, during the left and right swing of the feeding square tube, the ore is more evenly transported into the hopper of the ore transport vehicle.

[0018] 2. In this invention, during the left and right swinging of the feeding square tube, two front and rear guide blocks move together. The two guide blocks drive two driven wheels to roll back and forth along the top of the left and right side boxes of the ore transport vehicle's bucket via a reciprocating screw, thereby driving the reciprocating screw to rotate. The rotation of the reciprocating screw drives two threaded sleeves connected to it to alternately move away from each other and move closer to each other. When the two threaded sleeves move away from each other, the connecting arm drives the slider to move along the slide groove. The slider's movement drives the connecting beam and scraper to move together via the slide rod, causing the front and rear scrapers to move away from each other, spreading the ore transported by the feeding square tube to both sides of the bucket, preventing the ore from accumulating in the middle of the bucket.

[0019] 3. In this invention, the reciprocating screw rotates, and the meshing action of the driving gear and the driven gear drives the driven shaft to rotate. The driven shaft drives the two eccentric rods to rotate together. The rotation of the eccentric rods generates a deflection force effect and has a sliding connection with the strip groove, driving the pressure head, compaction rod and compaction plate to swing up and down. The up and down swinging compaction plate further compacts the flattened ore.

[0020] 4. In this invention, the slider movement also drives the right-angle frame to move together via the sliding rod. The movement of the right-angle frame drives the guide rod, end cap, and second spring to move together, causing the guide rod to move along the inner wall of the guide groove away from the feeding square tube until the guide rod slides out from the end of the guide groove. The rebound force of the second spring pushes the left and right guide rods to move towards the middle, so that the outer wall of the guide rod abuts against the inclined surface of the end of the guide block. At the same time, the reciprocating screw drives the screw sleeve to slide towards the feeding square tube. Further, the slider is driven to slide back along the slide groove via the connecting arm. The slider sliding back drives the sliding rod, connecting beam, and scraper to move together. The sliding rod also drives the right-angle frame, guide rod, end cap, and second spring to move back together, causing the guide rod to slide upward along the inclined surface of the end of the guide block. The right-angle frame drives the sliding rod, connecting beam, scraper, and spring support to move upward, ensuring that the scraper is in an upward state during the back movement, so that its bottom does not contact the ore and therefore does not scrape the ore spread in the previous step back again.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1-9 The technical solution provided by the present invention specifically includes the following embodiments:

[0033] Example 1

[0034] An automatic conveying and loading device for mining in a mining area includes a conveyor 1, a fixed frame 2 at one end of the conveyor 1, and a loading and feeding component at the top of the fixed frame 2.

[0035] The loading and feeding component includes two side panels 301 fixedly installed on the top of the fixed frame 2. The two side panels 301 are arranged front to back. Two first positioning pins 302, arranged left to right, are fixedly installed on the upper part of the side panels 301 that are close to each other. The outer wall of each first positioning pin 302 is hinged with a first hinge block 303. A first guide groove tile 304 is fixedly installed between the two first hinge blocks 303 on the left and the two first hinge blocks 303 on the right. There are two first guide groove tiles 304. The two first guide groove tiles 304 that are close to each other are provided with a telescopic groove 305. A second guide groove tile 306 is slidably installed inside the telescopic groove 305. A funnel 307 is movably provided between the side panels 301. Two second positioning pins 308 are fixedly installed on the front and rear walls of the funnel 307. The outer walls of the second positioning pins 308 are hinged with second hinge blocks 3010. The second hinge blocks 3010 are fixedly installed at the end of the second guide groove tile 306 away from the first guide groove tile 304. The front and rear parts of the funnel 307 are fixedly installed with a cantilever plate 3011. The top of the cantilever plate 3011 is fixedly installed with a rodless cylinder 3012. Two front and rear distributed smooth rods 3013 are fixedly installed inside the fixed frame 2. The smooth rods 3013 movably pass through the inside of the rodless cylinder 3012. The bottom of the funnel 307 is movably provided with a feeding square tube 3015.

[0036] Height adjustment seats 3016 are fixedly installed at the front and rear of the feeding square tube 3015. The height adjustment seats 3016 are located at the bottom of the cantilever plate 3011, and a hydraulic cylinder 3017 is fixedly installed at the bottom of the cantilever plate 3011. The bottom of the output rod of the hydraulic cylinder 3017 is fixedly connected to the top of the height adjustment seat 3016. A corrugated telescopic steel sleeve 3014 is fixedly installed between the bottom of the funnel 307 and the top of the feeding square tube 3015. The interior of the funnel 307 and the interior of the feeding square tube 3015 are connected through the corrugated telescopic steel sleeve 3014.

[0037] In this embodiment, the ore transport vehicle is moved inside the fixed frame 2, so that the truck bed of the ore transport vehicle is located at the bottom of the feeding square tube 3015. Then, two hydraulic cylinders 3017 are activated. The output rods of the two hydraulic cylinders 3017 push the two height adjustment seats 3016 and the feeding square tube 3015 downward. Then, the ore is transported between the two side panels 301 by the conveyor 1. Under the guiding action of the two first guide groove tiles 304 and the second guide groove tiles 306 on the left and right, the ore can flow smoothly into the inside of the funnel 307. Then, it is transported into the truck bed of the ore transport vehicle through the corrugated telescopic steel sleeve 3014 and the feeding square tube 3015. At the same time, the two rodless cylinders 3012 swing left and right along the two smooth rods 3013 under hydraulic action. The hydraulic drive principle of the rodless cylinders 3012 and the smooth rods 3013 is a prior art. Without going into details, the two rodless cylinders 3012 move left and right, causing the feeding square tube 3015, the corrugated telescopic steel sleeve 3014, and the funnel 307 to swing left and right together. When the funnel 307 moves to the left, a second guide groove tile 306 located at the left end of the funnel 307 slides into the interior of a telescopic groove 305 connected to it, while the second guide groove tile 306 located at the right end of the funnel 307 slides outward along the telescopic groove 305 connected to it. When the funnel 307 slides to the right, the opposite is true. This ensures that during the left and right swing of the funnel 307, the two first guide groove tiles 304 and the second guide groove tiles 306 always have the function of guiding the ore, allowing it to smoothly enter the interior of the funnel 307. Thus, during the left and right swing of the feeding square tube 3015, the ore is more evenly transported into the hopper of the ore transport vehicle.

[0038] Furthermore, the left and right sides of the funnel 307 are provided with relief grooves 309. The relief grooves 309 are located on the bottom periphery of the second material guiding groove tile 306. By providing relief grooves 309, it is ensured that the second material guiding groove tile 306 will not interfere with the funnel 307.

[0039] Furthermore, two reinforcing rods 3001 are fixedly installed between the upper part of the two side panels 301 that are close to each other. By setting the two reinforcing rods 3001, the connection strength between the two side panels 301 is strengthened, making the two side panels 301 more secure.

[0040] Example 2

[0041] The front and rear of the feeding square tube 3015 are equipped with loading and leveling components. These components include guide blocks 401 fixedly installed at the front and rear of the feeding square tube 3015, and a height adjustment seat 3016 located around the guide blocks 401. The left and right sides of the guide blocks 401 are each provided with a sliding groove 402. A slider 403 is slidably installed inside each of the left and right sliding grooves 402. A sliding hole 404 is provided through the top of each slider 403, and a sliding rod 405 is slidably installed inside the sliding hole 404. The bottom of the two slide bars 405 are connected to the connecting beam 406. The two ends of the connecting beam 406 are connected to the scraper 407. The bottom of the left and right slide bars 403 are fixedly installed with the connecting arm 408. The bottom of the two connecting arms 408 are connected to the threaded sleeve 409. The internal thread of the threaded sleeve 409 is connected to the reciprocating screw 4010. The reciprocating screw 4010 moves through the front and rear of the feeding square tube 3015. The two ends of the reciprocating screw 4010 are fixedly installed with the driven wheel 4011.

[0042] In this embodiment, the output rods of two hydraulic cylinders 3017 push two height adjustment seats 3016 and the feeding square tube 3015 downward, causing the corrugated telescopic steel sleeve 3014 to extend downward. The downward movement of the feeding square tube 3015, via two guide blocks 401, drives two reciprocating screws 4010 and two driven wheels 4011 to move downward together until the bottoms of the two reciprocating screws 4010 abut against the tops of the side panels of the ore transport vehicle's cargo bed. This allows the feeding square tube 3015 to swing left and right, causing the two front and rear guide blocks 401 to move together. The two guide blocks 401, through the reciprocating screws 4010, drive the two driven wheels 4011. The reciprocating screw 4010 rotates back and forth along the top of the left and right side panels of the ore transport vehicle. The rotation of the reciprocating screw 4010 drives the two threaded sleeves 409 connected to it to alternately move away from each other and move closer to each other. When the two threaded sleeves 409 move away from each other, the connecting arm 408 drives the slider 403 to move along the slide groove 402. The movement of the slider 403 drives the connecting beam 406 and the scraper 407 to move together through the slide rod 405. This causes the two scrapers 407 to move away from each other, spreading the ore conveyed by the feeding square tube 3015 to both sides of the truck bed, preventing the ore from accumulating in the middle of the truck bed.

[0043] Example 3

[0044] Spring supports 4013 are fixedly installed on the outer wall of the slide rod 405. The spring supports 4013 are located at the bottom of the slider 403. A first spring 4014 is sleeved on the periphery of the slide rod 405. The first spring 4014 is fixedly installed between the top of the spring support 4013 and the bottom of the slider 403. A right-angle bracket 4015 is fixedly installed on the top of the slide rod 405. A guide hole 4016 is opened through the side of the right-angle bracket 4015 near the guide block 401. A guide rod 4017 is slidably installed inside the guide hole 4016. An end cap 4018 is fixedly installed on the end of the guide rod 4017 away from the guide block 401. A second spring 4019 is sleeved on the periphery of the guide rod 4017. The second spring 4019 is fixedly installed between the side of the right-angle bracket 4015 and the end cap 4018.

[0045] Guide grooves 4001 are provided on the left and right sides of the guide block 401. The guide grooves 4001 are located on the top of the slide 402, and the specifications of the guide grooves 4001 are compatible with the specifications of the guide rod 4017. Two inclined grooves 4002 are provided on the top of the guide block 401 near the end of the feeding square tube 3015. The inclined grooves 4002 are connected to the interior of the guide grooves 4001. The top angle of the end of the guide block 401 away from the feeding square tube 3015 is set at a 45° angle.

[0046] In this embodiment, the slider 403 moves away from the feeding square tube 3015, and also moves the right-angle frame 4015 along with it via the slide rod 405. The movement of the right-angle frame 4015 causes the guide rod 4017, the end cap 4018, and the second spring 4019 to move together, so that the guide rod 4017 moves along the inner wall of the guide groove 4001 away from the feeding square tube 3015 until the guide rod 4017 slides out from the end of the guide groove 4001. The rebound force of the second spring 4019 pushes the two guide rods 4017 to move towards the middle, so that the outer wall of the guide rod 4017 abuts against the 45° inclined surface at the end of the guide block 401. At the same time, the reciprocating screw 4010 drives the screw sleeve 409 to move closer to the feeding square tube 301. The slider 403 slides back along the groove 402 via the connecting arm 408. The sliding back of the slider 403 causes the sliding rod 405, the connecting beam 406, and the scraper 407 to move together. The sliding rod 405 also causes the right-angle bracket 4015, the guide rod 4017, the end cap 4018, and the second spring 4019 to move back together. This causes the guide rod 4017 to slide upward along the 45° inclined plane at the end of the guide block 401. The right-angle bracket 4015 causes the sliding rod 405, the connecting beam 406, the scraper 407, and the spring support 4013 to move upward. This ensures that the scraper 407 is in an upward state during the backward movement, so that its bottom does not contact the ore and therefore does not scrape the ore spread out in the previous step back.

[0047] Example 4

[0048] The connecting beam 406 is equipped with a loading and compaction component, which includes a compaction rod 501 that is slidably installed inside the connecting beam 406. The compaction rod 501 movably passes through the top and bottom of the connecting beam 406. A compaction plate 502 is fixedly installed at the bottom of the compaction rod 501. The compaction plate 502 is located inside the scraper 407. A pressure head 503 is fixedly installed at the top of the compaction rod 501. The pressure head 503 is located between two sliding rods 405. A strip groove 504 is opened through the side of the pressure head 503 near the feeding square tube 3015. A driven shaft 505 is rotatably installed at the front and rear of the feeding square tube 3015. The driven shaft 505 is located at the bottom of the reciprocating screw 4010. Two eccentric rods 506 distributed front and rear are fixedly installed on the outer wall of the driven shaft 505. The outer wall of the eccentric rod 506 is slidably connected to the inside of the strip groove 504.

[0049] A driven gear 508 is fixedly installed on the outer wall of the driven shaft 505, and a driving gear 507 is fixedly installed on the outer wall of the reciprocating screw 4010. The bottom of the driving gear 507 meshes with the top of the driven gear 508. A gear housing 509 is fixedly installed on the rear wall of the feeding square tube 3015. The gear housing 509 is located around the driving gear 507 and the driven gear 508.

[0050] In this embodiment, when the feeding square tube 3015 swings left and right, the reciprocating screw 4010 rotates. Through the meshing of the driving gear 507 and the driven gear 508, the driven shaft 505 rotates. The driven shaft 505 drives the two eccentric rods 506 to rotate together. The rotation of the eccentric rods 506 generates a deflection force and has a sliding connection with the strip groove 504, driving the pressure head 503, the compaction rod 501 and the compaction plate 502 to swing up and down. The compaction plate 502, which swings up and down, further compacts the flattened ore.

[0051] Furthermore, a bearing bracket 4012 is fixedly installed at the bottom of the guide block 401 away from the feeding square tube 3015. The bearing bracket 4012 is rotatably connected to the reciprocating screw 4010 and the driven shaft 505 through bearings. By setting the bearing bracket 4012, it provides lateral support for the reciprocating screw 4010 and the driven shaft 505, making the rotation of the reciprocating screw 4010 and the driven shaft 505 more stable.

[0052] This automatic conveying and loading device for mining operations moves the ore transport vehicle into the fixed frame 2, positioning the vehicle's cargo bed at the bottom of the loading square tube 3015. Then, two hydraulic cylinders 3017 are activated. The output rods of these cylinders push two height adjustment seats 3016, along with the loading square tube 3015, downwards. This causes the corrugated telescopic steel sleeve 3014 to extend downwards. The downward movement of the loading square tube 3015, via two guide blocks 401, drives two reciprocating lead screws 4010 and two... Driven wheel 4011 moves downward together until the bottom of the two reciprocating screws 4010 abuts against the top of the box plates on the left and right sides of the ore transport vehicle's bucket, stopping the two hydraulic cylinders 3017. Then, the conveyor 1 transports the ore between the two side panels 301. Under the guiding action of the two first guide groove tiles 304 and the second guide groove tiles 306 on the left and right sides, the ore can flow smoothly into the inside of the funnel 307, and then be transported into the bucket of the ore transport vehicle through the corrugated telescopic steel sleeve 3014 and the feeding square tube 3015.

[0053] Meanwhile, the two rodless cylinders 3012 oscillate left and right along the two smooth rods 3013 under hydraulic pressure. The hydraulic drive principle of the rodless cylinders 3012 and the smooth rods 3013 is existing technology and will not be elaborated here. The left and right movement of the two rodless cylinders 3012 causes the feeding square tube 3015, the corrugated telescopic steel sleeve 3014, and the funnel 307 to oscillate left and right together. When the funnel 307 moves to the left, a second guide groove tile 306 located at the left end of the funnel 307 slides into the interior of a telescopic groove 305 connected to it. The second guide groove tile 306 located at the right end of the funnel 307 slides outward along a telescopic groove 305 connected to it. When the funnel 307 slides to the right, the opposite is true. During the left and right swing of the funnel 307, the two first guide groove tiles 304 and the second guide groove tile 306 on the left and right always have the function of guiding the ore, so that it can smoothly enter the interior of the funnel 307. Thus, during the left and right swing of the feeding square tube 3015, the ore is more evenly transported into the hopper of the ore transport vehicle.

[0054] During the oscillation of the feeding square tube 3015, it drives the two front and rear guide blocks 401 to move together. The two guide blocks 401 drive the two driven wheels 4011 to roll back and forth along the top of the left and right side panels of the ore transport vehicle's bucket via the reciprocating screw 4010, thereby driving the reciprocating screw 4010 to rotate. The rotation of the reciprocating screw 4010 drives the two threaded sleeves 409 connected to it to alternately move away from each other and move closer to each other. When the two threaded sleeves 409 move away from each other, they drive the slider 403 to move along the slide groove 402 via the connecting arm 408. The movement of the slider 403 drives the connecting beam 406 and the scraper 40 via the slide rod 405. 7. Move together, so that the front and rear scrapers 407 move away from each other, spreading the ore conveyed by the feeding square tube 3015 to both sides of the truck bed, avoiding the ore from accumulating in the middle of the truck bed. At the same time, the reciprocating screw 4010 rotates, which drives the driven shaft 505 to rotate through the meshing of the driving gear 507 and the driven gear 508. The driven shaft 505 drives the two eccentric rods 506 to rotate together. The rotation of the eccentric rods 506 generates a deflection force effect and slides with the strip groove 504, driving the pressure head 503, the compaction rod 501 and the compaction plate 502 to swing up and down. The up and down swinging compaction plate 502 further compacts the spread ore.

[0055] Simultaneously, the movement of slider 403 also drives the right-angle bracket 4015 to move along with slider 405. The movement of right-angle bracket 4015 drives guide rod 4017, end cap 4018, and second spring 4019 to move together, causing guide rod 4017 to move along the inner wall of guide groove 4001 away from feeding square tube 3015 until guide rod 4017 slides out from the end of guide groove 4001. The rebound force of second spring 4019 pushes the two guide rods 4017 to move towards the middle, so that the outer wall of guide rod 4017 abuts against the 45° inclined surface at the end of guide block 401. Simultaneously, the reciprocating screw 4010 drives the screw sleeve 409 to slide closer to the feeding square tube 3015, further driving the slider 403 to slide back along the slide groove 402 via the connecting arm 408. The sliding back of the slider 403 drives the slide rod 405, connecting beam 406, and scraper 407 to move together. The slide rod 405 also drives the right-angle bracket 4015, guide rod 4017, end cap 4018, and second spring 4019 to move back together, causing the guide rod 4017 to slide upward along the 45° inclined surface at the end of the guide block 401. Through the right-angle bracket 4015, the slide rod 405, connecting beam 406, and scraper 407 move together. The beam 406, scraper 407, and spring support 4013 move upwards, ensuring that the scraper 407 is in an upward-lifted state during its retraction, thus preventing its bottom from contacting the ore and preventing the previously spread ore from being scraped back. During this process, the upward movement of the spring support 4013 compresses and stores force in the first spring 4014. After the guide rod 4017 slides along the 45° inclined surface at the end of the guide block 401 to the top of the guide block 401, it continues to slide along the top of the guide block 401 until it reaches the top opening of the inclined groove 4002. The rebound force of the first spring 4014 pushes the spring support 4013 upwards. 013 moves downward along with the slide rod 405, further driving the right-angle bracket 4015, guide rod 4017, end cap 4018 and second spring 4019 to slide downward, causing the guide rod 4017 to slide back into the guide groove 4001. During this process, due to the wedge force between the inner wall of the inclined groove 4002 and the end of the guide rod 4017, the guide rod 4017 slides along the inner wall of the guide hole 4016 away from the guide block 401 as it slides downward along the inclined groove 4002, causing the end cap 4018 to move together, resulting in the second spring 4019 being stretched and generating a rebound force.
