Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering, and more specifically, to a loader with an adjustable center of gravity. Background Technology

[0002] A scraper is a large, efficient earthmoving machine that integrates soil shoveling, transporting, and unloading. As an important type of engineering machinery, scrapers play an irreplaceable role in earthwork construction, bulk heavy object shoveling and transportation, and site leveling due to their high efficiency, practicality, and versatility.

[0003] Although scrapers can currently perform functions such as shoveling, transporting, and unloading soil, when unloading materials, some materials have large particles or high coefficients of friction, and may not be able to slide out completely and smoothly by gravity and the angle of the bucket tilting alone. If the unloading is not thorough, the residue will affect the loading capacity of the next bucket, or even mix in different types of materials. Furthermore, if there is a jam in the bucket, the operator needs to operate the bucket to shake it multiple times or tilt it repeatedly, which affects the unloading speed. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this invention is to provide a loader with an adjustable center of gravity.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] An adjustable center of gravity loader includes a vehicle body, a mobile unit and a working component mounted on the vehicle body, a cab fixed to the vehicle body, and a bucket connected to the working component; The bucket is connected to a pushing unit, which includes a shovel seat that is slidably connected to the inner wall of the bucket at both ends, a lower pushing plate that is rotatably connected to the upper end of the shovel seat, an upper pushing plate that is rotatably connected to the other end of the lower pushing plate, and a pushing drive unit located inside the bucket and connected to the shovel seat. The other end of the upper pushing plate is rotatably connected to the inner wall of the bucket. The pushing drive unit includes a hydraulic rod 1 with one end rotatably connected to the inner wall of the bucket, and a pushing unit with one end connected to the inner wall of the bucket and the other end connected to the shovel seat.

[0007] Furthermore, the pushing unit includes a connecting plate 1 with one end rotatably connected to the inner wall of the bucket, a connecting plate 2 rotatably connected to the other end of the connecting plate 1, a slide groove 1 opened on one side of the connecting plate 1, and a slide seat 1 slidably connected in the slide groove 1. The other end of the connecting plate 2 is rotatably connected to one side of the shovel seat, and the telescopic end of the hydraulic rod 1 is rotatably connected to the slide seat 1.

[0008] Furthermore, the hydraulic counterweight assembly includes a second liquid storage unit fixed to the lower left side of the vehicle body, a first liquid storage unit fixed to the lower right side of the vehicle body, and a hydraulic delivery unit, wherein the hydraulic delivery unit is connected to the first liquid storage unit and the second liquid storage unit.

[0009] Furthermore, both the liquid storage section one and the liquid storage section two are equipped with multiple anti-surge plates.

[0010] Furthermore, the bucket is also connected to a support and push assembly, which includes a hydraulic rod 2 with one end rotatably connected to the inner wall of the bucket, a slide groove 2 opened on one side of the lower push plate, a slide seat 2 slidably connected inside the slide groove 2, and a connecting part fixed to one side of the slide seat 2, and the telescopic end of the hydraulic rod 2 is rotatably connected to the connecting part.

[0011] Furthermore, a rack is fixedly connected to the inner wall of the slide groove two, and a vibration stripping unit is connected to one side of the slide seat two. The vibration stripping unit includes a movable groove one opened inside the slide seat two for accommodating the rack, a gear one rotatably connected inside the movable groove one and meshing with the rack, two flanges integrally formed on one side of the slide seat two, a gear two whose two ends are respectively rotatably connected to the two flanges and meshing with the gear one, two ratchet wheels and an incomplete gear respectively rotatably connected to one side of the two flanges, and vibration parts respectively connected to one side of the two flanges. The two ends of the gear two pass through the two flanges and are fixedly connected to the two ratchet wheels.

[0012] Furthermore, the vibration unit includes an integrally formed vertical plate on one side of the flange, a guide rod with both ends fixedly connected to the vertical plate and the slide block, a counterweight block slidably connected to one side of the flange and movably sleeved outside the guide rod, a toothed groove on one side of the counterweight block, and a spring 1 sleeved outside the guide rod, with both ends of the spring 1 connected to the counterweight block and the vertical plate, respectively.

[0013] Furthermore, the incomplete gear has a hollow cavity inside, and two inner rings are fixed to the inner wall of the hollow cavity. Multiple stop claws are rotatably connected between the two inner rings.

[0014] Furthermore, a damping seat is fixedly connected to one side of the lower push plate, and a hydraulic vibrator is fixedly connected to one side of the damping seat. A groove is formed on one side of the lower push plate, and a plate body is movably connected in the groove. Multiple movable slots are formed inside the lower push plate, and movable seats are movably connected inside each of the multiple movable slots. A connecting column is fixedly connected to one side of each of the multiple movable seats, and the other end of each of the multiple connecting columns is fixedly connected to one side of the plate body. A spring is sleeved on the outside of each connecting column, and the two ends of the spring are respectively connected to the inner wall of the movable slot and the movable seat. A transmission seat is fixedly connected to the vibration generating end of the hydraulic vibrator, and the other end of the transmission seat passes through the lower push plate and is fixedly connected to one side of the plate body.

[0015] Furthermore, an opening and a pipe slot are provided on one side of the bucket, and a discharge flap is rotatably connected in the opening.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) This scheme is equipped with a material pushing unit. When the bucket is unloading, the material pushing drive unit pushes the material shovel seat to move. The movement of the material shovel seat drives the lower push plate and the upper push plate to move. The movement of the lower push plate and the upper push plate can push the material inside the bucket directly from back to front, so that the material is removed from the bucket, destroying the material arch bridge and hanging phenomenon, allowing the material to collapse as a whole and be discharged in the direction of the flow. Only one complete stroke is needed to push out the vast majority of the material, reduce cross-contamination, increase the loading rate, greatly shorten the unloading time, and improve the unloading efficiency.

[0017] (2) This scheme is equipped with a support and push component. When the bucket is shoveling and loading materials, the support and push component can support the lower push plate and ensure the stability of the pushing unit when the bucket is loaded with materials. When the pushing drive unit pushes the shovel seat to move to push materials, the hydraulic rod 2 pushes the slide 2 and the lower push plate to move, which can apply force to the lower push plate and support the lower push plate to ensure the stability of the lower push plate during the pushing process.

[0018] (3) This scheme is equipped with a vibration unloading unit. When the pusher plate moves to push the material, the hydraulic rod 2 can drive the slide 2 to move in the slide groove 2. The rack in the slide groove 2 drives the vibration unit to work. The vibration unit applies an impact to the slide 2 and causes the slide 2 to vibrate. The vibration acts on the pusher plate from the slide 2, causing the pusher plate to vibrate slightly. The vibration can break the static friction between the pusher plate and the material, making it easier for the material to slide on the surface of the pusher plate and reducing the pushing force required by the pusher plate. For wet clay or minerals that are easy to clump, the vibration can loosen the material and shake off some of the material stuck to the pusher plate. At the same time, it can also destroy the arch bridge that the material may form at the bucket opening, avoid blockage, and improve the thoroughness of unloading. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1 to 10 An adjustable center of gravity loader includes a vehicle body 2, a mobile unit 1 and a working component 3 mounted on the vehicle body 2, a cab 4 fixed to the vehicle body 2, and a bucket 5 connected to the working component 3. The working component 3 is a hydraulic system that can drive the bucket 5 to rotate, enabling the bucket 5 to perform material shoveling and unloading actions. The bucket 5 has an opening and a pipeline slot 52 on one side, and a unloading flap 51 is rotatably connected in the opening.

[0023] The bucket 5 is internally connected to a pushing unit 6, which includes a shovel seat 61 with both ends slidingly connected to the inner wall of the bucket 5, a lower pushing plate 62 rotatably connected to the upper end of the shovel seat 61, an upper pushing plate 63 rotatably connected to the other end of the lower pushing plate 62, and a pushing drive unit 64 located inside the bucket 5 and connected to the shovel seat 61. The other end of the upper pushing plate 63 is rotatably connected to the inner wall of the bucket 5. The pushing drive unit 64 includes a hydraulic rod 641 with one end rotatably connected to the inner wall of the bucket 5, and a pushing unit 6 with one end connected to the inner wall of the bucket 5 and the other end connected to the shovel seat 61. The telescopic end of the hydraulic rod 641 is connected to the pushing unit 6. The lower end of the vehicle body 2 is also connected to a hydraulic counterweight assembly.

[0024] The pushing unit 6 includes a connecting plate 642 with one end rotatably connected to the inner wall of the bucket 5, a connecting plate 643 rotatably connected to the other end of the connecting plate 642, a sliding groove 644 opened on one side of the connecting plate 642, and a sliding seat 645 slidably connected in the sliding groove 644. The other end of the connecting plate 643 is rotatably connected to one side of the shovel seat 61, and the telescopic end of the hydraulic rod 641 is rotatably connected to the sliding seat 645.

[0025] By adopting the above technical solution, during use, the oil supply line of the hydraulic system of the loader can pass through the pipe slot 52 into the bucket 5 and connect to the hydraulic rod 641. When the bucket 5 is tilted to unload material, the hydraulic rod 641 extends and pushes the slide block 645 to move within the slide groove 644. At the same time, the hydraulic rod 641 can also push the connecting plate 642 to rotate. The rotation of the connecting plate 642 pushes the shovel seat 61 to move inside the bucket 5 through the connecting plate 643. The shovel seat 61 can remove material from the bottom wall of the bucket 5. When the shovel seat 61 moves, it can also drive the lower push plate 62 to move. The movement of the lower push plate 62 drives the upper push plate 643 to move. 3. Rotation causes the lower pusher plate 62 and the upper pusher plate 63 to move. The rotation of the lower pusher plate 62 and the upper pusher plate 63 can directly push the material inside the bucket 5 from back to front, so that the material is removed from the bucket 5, breaking the material arching and hanging phenomenon, allowing the material to collapse as a whole and be discharged smoothly. Only one full stroke is needed to push out the vast majority of the material, reducing cross-contamination, increasing the loading rate, greatly shortening the unloading time, and improving the unloading efficiency. After the material is pushed out, the hydraulic rod 641 retracts and drives the shovel seat 61 to reset. By rotating to open the unloading flap 51, the material that has entered the lower pusher plate 62 and the shovel seat 61 can be discharged from the opening of the bucket 5.

[0026] like Figure 10 and Figure 11As shown, the hydraulic counterweight assembly includes a second liquid storage section 16 fixed to the lower left side of the vehicle body 2, a first liquid storage section 14 fixed to the lower right side of the vehicle body 2, and a hydraulic delivery section 15, and the hydraulic delivery section 15 is connected to the first liquid storage section 14 and the second liquid storage section 16.

[0027] Both the first liquid storage section 14 and the second liquid storage section 16 are equipped with multiple anti-surge baffles. The design of multiple anti-surge baffles is to prevent the liquid from sloshing inside the first liquid storage section 14 and the second liquid storage section 16 when the vehicle body 2 moves. The design of the anti-surge baffles is the same as that in existing tank trucks and is a mature existing technology, so it will not be described in detail here. At the same time, both the first liquid storage section 14 and the second liquid storage section 16 are equipped with liquid level sensors, and an inertial measurement unit (IMU) is also installed on the vehicle body 2 to monitor the pitch and roll angles of the vehicle body as auxiliary control signals.

[0028] By adopting the above technical solution, when the bucket 5 is unloaded, the liquid (hydraulic oil or water) in the first reservoir 14 is sent to the second reservoir 16 through the hydraulic fluid supply unit 15, which increases the force on the front wheels and improves the grip. When the bucket 5 is fully loaded, the liquid (hydraulic oil or water) in the second reservoir 16 is sent to the first reservoir 14 through the hydraulic fluid supply unit 15, which increases the force on the rear wheels and counteracts the uneven power caused by the rearward shift of the center of gravity. By changing the position of the liquid mass, the downward pressure on the front and rear wheels is adjusted, making the grip more balanced. The hydraulic fluid delivery unit 15 adopts a design of pump body + reversing valve + check valve. The hydraulic fluid delivery unit 15 is also equipped with a controller, which receives signals from the inertial measurement unit and controls the operation of the pump body and reversing valve according to the preset logic algorithm. This method of alternating fluid delivery between the front and rear chambers to adjust the center of gravity is a mature existing technology. For example, ships need to pump seawater to transfer between the port and starboard and front and rear compartments to adjust the ship's pitch or roll and ensure stability during navigation. Therefore, the specific composition and principle of the hydraulic counterweight component will not be explained in detail here.

[0029] like Figure 3 and Figure 4 As shown, the bucket 5 is also connected to a support and push assembly 7, which includes a hydraulic rod 74 with one end rotatably connected to the inner wall of the bucket 5, a slide groove 71 opened on one side of the lower push plate 62, a slide seat 72 slidably connected inside the slide groove 71, and a connecting part 73 fixedly connected to one side of the slide seat 72. The telescopic end of the hydraulic rod 74 is rotatably connected to the connecting part 73.

[0030] By adopting the above technical solution, when hydraulic rod 641 is working, it controls hydraulic rod 74 to work. Hydraulic rod 74 extends and pushes the lower pusher plate 62 toward the opening of the bucket 5. At the same time, hydraulic rod 74 can also push slide 72 to slide in slide groove 71. When the bucket 5 is shoveling and loading materials, hydraulic rod 74 can support the lower pusher plate 62 to ensure the stability of the pushing unit 6 when the bucket 5 is loaded with materials. When the pushing drive unit 64 pushes the shovel seat 61 to move for pushing, hydraulic rod 74 pushes slide 72 and lower pusher plate 62 to move, which can apply force to the lower pusher plate 62 and support it for pushing, ensuring the stability of the lower pusher plate 62 during the pushing process.

[0031] like Figures 5-7 As shown, a rack 81 is fixedly connected to the inner wall of the slide groove 71. A vibration stripping unit 8 is connected to one side of the slide block 72. The vibration stripping unit 8 includes a movable groove 82 opened inside the slide block 72 to accommodate the rack 81, a gear 83 rotatably connected inside the movable groove 82 and meshing with the rack 81, two flanges 84 integrally formed on one side of the slide block 72, a gear 85 rotatably connected to the two flanges 84 at both ends and meshing with the gear 83, two ratchet wheels 86 and an incomplete gear 87 rotatably connected to one side of the two flanges 84, and a vibration part 88 connected to one side of the two flanges 84. The two ends of the gear 85 pass through the two flanges 84 and are fixedly connected to the two ratchet wheels 86.

[0032] The vibration unit 88 includes an upright plate 881 integrally formed on one side of the flange 84, a guide rod 882 whose two ends are fixed to the upright plate 881 and the slide block 72 respectively, a counterweight 884 slidably connected to one side of the flange 84 and movably sleeved on the outside of the guide rod 882, a toothed groove 885 formed on one side of the counterweight 884, and a spring 883 sleeved on the outside of the guide rod 882, with the two ends of the spring 883 connected to the counterweight 884 and the upright plate 881 respectively.

[0033] The incomplete gear 87 has a hollow cavity inside, and two inner rings 872 are fixed to the inner wall of the hollow cavity. Multiple stop claws 871 are rotatably connected between the two inner rings 872.

[0034] By adopting the above technical solution, when the hydraulic rod 74 pushes the slide block 72 to slide in the slide groove 71, the rack 81 can drive the gear 83 to rotate. The rotation of the gear 83 drives the gear 85 and the two ratchet wheels 86 to rotate. When the ratchet wheels 86 rotate clockwise, they can drive the stop pawl 871 and the incomplete gear 87 to rotate. The rotation of the incomplete gear 87 can drive the counterweight 884 to move towards the spring 883 through the tooth groove 885. The spring 883 is compressed. When the incomplete gear 87 moves out of the tooth groove 885, the spring 883 releases its elastic potential energy and pushes the counterweight 884 towards the slide groove 71. When slide seat 72 moves, counterweight block 884 strikes slide seat 72 and causes it to vibrate. The vibration from slide seat 72 acts on the lower push plate 62, causing it to vibrate slightly. This vibration breaks the static friction between the lower push plate 62 and the material, making it easier for the material to slide on the surface of the lower push plate 62 and reducing the thrust required by the lower push plate 62. For wet clay or easily lumpy minerals, the vibration can loosen the material, shaking off some of the material stuck to the lower push plate 62. It also breaks up any arch bridges that may form in the bucket opening 5, preventing blockages and improving the thoroughness of unloading.

[0035] like Figure 1 , Figure 8 and Figure 9 As shown, a damping seat 92 is fixedly connected to one side of the lower push plate 62, and a hydraulic vibrator 9 is fixedly connected to one side of the damping seat 92. A groove is opened on one side of the lower push plate 62, and a plate body 10 is movably connected in the groove. Multiple movable slots 17 are opened inside the lower push plate 62, and movable seats 11 are movably connected inside each of the multiple movable slots 17. A connecting column 12 is fixedly connected to one side of each of the multiple movable seats 11, and the other end of each of the multiple connecting columns 12 is fixedly connected to one side of the plate body 10. A spring 13 is sleeved on the outside of the connecting column 12, and the two ends of the spring 13 are respectively connected to the inner wall of the movable slot 17 and the movable seat 11. A transmission seat 91 is fixedly connected to the vibration generating end of the hydraulic vibrator 9, and the other end of the transmission seat 91 passes through the lower push plate 62 and is fixedly connected to one side of the plate body 10.

[0036] By adopting the above technical solution, when the pushing plate 62 moves to its maximum stroke, the vibration unloading unit 8 cannot apply vibration force to the pushing plate 62. By making the hydraulic vibrator 9 work, the vibration generated by the hydraulic vibrator 9 acts on the plate 10 through the transmission seat 91. The plate 10 will be displaced by the vibration, causing the plate 10 to move in the groove. The vibration generated by the hydraulic vibrator 9 directly acts on the plate 10. The amplitude of the vibration driven by the hydraulic vibrator 9 to the plate 10 is larger than that driven by the vibration unloading unit 8 to the plate 10. It can perform secondary vibration unloading of the remaining material on the plate 10, thereby improving the thoroughness of unloading.

[0037] Operating method: When the bucket 5 tilts to unload material, hydraulic rod 641 extends to push slide 645 to move within slide groove 644. Simultaneously, hydraulic rod 641 also drives connecting plate 642 to rotate. The rotation of connecting plate 642, through connecting plate 643, pushes shovel seat 61 to move inside the bucket 5, allowing shovel seat 61 to remove material from the bottom wall of the bucket 5. When shovel seat 61 moves, it also drives lower push plate 62 to move. The movement of lower push plate 62 drives upper push plate 63 to rotate. The rotation of lower and upper push plates 62 and 63 directly pushes the material inside the bucket 5 from back to front, removing the material from the bucket 5. When the bucket 5 is shoveling or loading material, hydraulic rod 74 supports lower push plate 62, ensuring the stability of the pushing unit 6 when the bucket 5 is loaded. When the pushing drive unit 64 pushes shovel seat 61 to move for pushing, hydraulic rod 74... 4. Pushing the slide block 72 and the lower push plate 62 can apply a force to the lower push plate 62, providing support for pushing the material; when the hydraulic rod 74 pushes the slide block 72 to slide in the slide groove 71, the rack 81 can drive the gear 83 to rotate. The rotation of the gear 83 drives the gear 85 and the two ratchet wheels 86 to rotate. When the ratchet wheels 86 rotate clockwise, they can drive the stop pawl 871 and the incomplete gear 87 to rotate. The rotation of gear 87 can drive the counterweight 884 to move towards the spring 883 through the tooth groove 885. The spring 883 is compressed. When the incomplete gear 87 moves out of the tooth groove 885, the spring 883 releases its elastic force and pushes the counterweight 884 towards the slide block 72. The counterweight 884 strikes the slide block 72 and causes the slide block 72 to vibrate. The vibration from the slide block 72 acts on the lower push plate 62, causing the lower push plate 62 to vibrate slightly.

[0038] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
