Description

Technical Field

[0001] This invention relates to the field of loading and unloading sanitation vehicles, specifically a new type of self-loading and self-unloading sanitation vehicle. Background Technology

[0002] Existing sanitation vehicles have a variety of functions, one of which is the chain-driven sanitation vehicle. The chain-driven sanitation vehicle uses chains, sprockets, and hydraulic cylinders as power components to move the garbage bins upwards and overturn them.

[0003] In existing technologies, the sliding cover of a sanitation truck's container requires manual opening and closing via an independent power system. Occasionally, due to operator error, the cover fails to open when garbage is being dumped, causing the garbage to spill onto the top of the container and scatter onto the ground. Alternatively, the cover may not close after garbage is dumped, resulting in a pungent odor spreading through the area where the sanitation truck has passed. Both of these situations cause discomfort to passersby and lead to complaints. To avoid these problems, a new type of self-loading and self-unloading sanitation truck is proposed.

[0060] 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.

[0061] Please see Figures 1 to 17In this embodiment of the invention, a novel self-loading and self-unloading sanitation vehicle includes a box body 1. The box body 1 includes sealing elements 107 and a bottom plate 108 connected to the vehicle body. A second hydraulic cylinder 3 is installed at the bottom end of a rotating assembly 8. Two sealing elements 107 are welded to the top end of the bottom plate 108. A rotating door 103 is rotatably connected to one end of the sealing element 107, and a side plate 104 is welded and fixed to the other end of the sealing element 107. A top cover 101 is fixedly connected to the top end of the side plate 104. The internal sliding connection is a sliding cover 102 that extends through to the outside of the top cover 101. A second hydraulic cylinder 3 is rotatably installed at the bottom end of the base plate 108. A first hydraulic cylinder 2 that drives the rotating door 103 to open and close is rotatably installed on the seal 107. An inner groove 105 is formed on one end face of a seal 107. Two guide rails 7 are symmetrically fixedly connected to the end face of the seal 107 along the vertical central axis of the inner groove 105. A sliding groove 701 formed along the trajectory of the guide rail 7 is opened inside the guide rail 7.

[0062] The sliding cover 102 in the fully slid-out state is fixedly connected to the side plate 104 by a locking assembly 9, which is distributed inside the side plate 104 and the sliding cover 102.

[0063] A power assembly 4 is installed at the top of the base plate 108 and inside the groove 105. The power assembly 4 is used to pull the rotating plate assembly 5 to slide along the track of the guide rail 7, and to rotate the rotating plate assembly 5 after it is moved to the highest position.

[0064] The top cover 101 has an internal receiving groove 106 for receiving the sliding cover 102. A sealing element 107 is formed at the position where the sliding cover 102 is released from the top cover 101. The vertical cross section of the sliding cover 102 has an "I" shaped structure.

[0065] Clamping components 6 are distributed at the bottom of the rotating plate assembly 5 and on the guide rail 7. The clamping components 6 are used to clamp the outer wall of the trash can.

[0066] It also includes: a rotating component 8 and a moving component 10, which are symmetrically connected to the two ends of the power component 4. The upward-moving power component 4 is used to drive the rotating component 8 and the moving component 10 to move, and the downward-moving power component 4 is used to drive the rotating component 8 and the moving component 10 to move in the opposite direction.

[0067] The moving component 10, which moves upward with the power component 4, is used to drive the locking component 9 to unlock. The moving component 10, which moves downward with the power component 4, is used to drive the locking component 9 from the unlocked state to the locked state.

[0068] In this embodiment: when the garbage in the trash can is poured into the container 1, the power component 4 is activated and the power component 4 moves upward until the power component 4 abuts against the rotating plate component 5. Under the pulling action of the power component 4, the rotating plate component 5 slides along the slide groove 701. The upward-moving power component 4 drives the rotating component 8 and the moving component 10 to perform actions, so as to achieve the purpose of unlocking and then pushing the sliding cover 102.

[0069] Since the upper half of the chute 701 is bent at a 90-degree angle, when the upper fixed rod 502 drives the connecting shaft to disengage from the vertical groove of the lower half of the chute 701, the bottom rod 409 is still located in the lower half of the chute 701. Therefore, the vertical displacement distance of the rotating plate assembly 5 is less than the vertical displacement distance of the bottom rod 409. At this time, the bottom rod 409 and the sliding column 407 squeeze the rotating plate assembly 5, so that the rotating plate assembly 5 rotates downward around the connecting shaft, so that the garbage in the trash can is poured into the container 1.

[0070] Please refer to this carefully. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 The power assembly 4 includes: a third hydraulic cylinder 401, a crossbar 402, a sprocket 403, a chain 404, a connector 405, a first fixed rod 406, a sliding column 407, a second fixed rod 408, and a bottom rod 409.

[0071] Hydraulic cylinder 401 is installed at the top of base plate 108 and located inside groove 105. Crossbar 402 is fixedly connected to the output end of hydraulic cylinder 401. Two sprockets 403 are rotatably connected to both ends of crossbar 402. Two chains 404 are respectively engaged with two sprockets 403. One end of sprocket 403 is fixedly connected to a protruding plate on the inner wall of groove 105. Connector 405 is fixedly connected to the other end of chain 404. Fixed rod 406 is connected to the end of connector 405 away from chain 404. Sliding column 407 is connected to the bottom end of fixed rod 406. Fixed rod 408 is connected to the outer wall of sliding column 407. Bottom rod 409 is fixedly connected to the bottom end of fixed rod 408.

[0072] In this embodiment: When the third hydraulic cylinder 401 is running, the third hydraulic cylinder 401 drives the two sprockets 403 to move upward through the crossbar 402. The sprockets 403 pull the connecting piece 405 upward through the chain 404. At this time, the sprockets 403 rotate, and the connecting piece 405 pulls the first fixed rod 406 and the sliding column 407 upward. The upward-moving sliding column 407 pulls the bottom rod 409 upward through the second fixed rod 408. At this time, the sliding column 407 moves upward along the sliding groove 410, and the two ends of the bottom rod 409 move upward along the sliding groove 701 until the sliding column 407 abuts against the top of the inner wall of the sliding groove 410. At this time, the upward-moving sliding column 407 can pull the rotating plate assembly 5 to move upward along the guide rail 7, while the upward-moving bottom rod 409 drives the rotating assembly 8 and the moving assembly 10 to perform actions respectively.

[0073] Please refer to this carefully. Figure 3 , Figure 4 , Figure 9 , Figure 10 The rotating plate assembly 5 includes: a rotating plate 501, an upper fixing rod 502, a hook 503, a pulley 504, and a vertical plate 505;

[0074] The rotating plate assembly 5 is slidably connected between the two guide rails 7;

[0075] The upper fixed rod 502 is fixedly connected to the top of the rotating plate 501. The hook 503 is integrally formed on one end face of the upper fixed rod 502. The two pulleys 504 are rotatably connected to the two ends of the upper fixed rod 502 respectively. The end of the pulley 504 away from the upper fixed rod 502 passes through the slide groove 701 through the connecting shaft. The end wall of the connecting shaft is formed with an anti-detachment part.

[0076] The vertical plate 505 is integrally formed on both sides of the rotating plate 501. The cross-section of the rotating plate 501 and the vertical plate 505 is in the shape of an "I". The vertical plate 505 is slidably connected to the two ends of the sliding column 407. A sliding groove 410 is provided at the contact position between the two ends of the vertical plate 505 and the sliding column 407 to allow the sliding column 407 to move up and down.

[0077] In this embodiment: Before starting the device, the bottom edge of the opening of the trash can is hooked to the hook 503. At this time, the vertical plate 505 is pulled by the sliding column 407, which drives the rotating plate 501 to move upward along the guide rail 7. The upward-moving rotating plate 501 drives the clamping assembly 6 to clamp the surface of the trash can. The rotating plate 501 pushes the upper fixed rod 502 to move. The upper fixed rod 502 drives the pulley 504 to rotate inside the guide rail 7, and the connecting shaft slides inside the slide groove 701.

[0078] Please refer to this carefully. Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 12 The two ends of the bottom rod 409 are slidably connected to the slide groove 701, and the bottom rod 409 passes through the slide groove 701. The bottom rod 409 in the up-and-down moving state is used to drive the rotating component 8 and the moving component 10 to move.

[0079] The rotating assembly 8 includes: a fixed gear 801, a fixed rod 802, a movable seat 803, a horizontal rack 804, a vertical groove 805, and a helical groove 806;

[0080] The movable seat 803 is fixedly connected to one end of the base rod 409. The outer wall of the fixed rod 802 is movably connected to the movable seat 803. The top outer wall of the movable seat 803 is rotatably connected to the fixed seat. The fixed seat is fixedly connected to the seal 107.

[0081] The fixed gear 801 is mounted on the top of the fixed rod 802, and the spiral groove 806 is formed on the outer wall of the sliding cover 102 and meshes with the fixed gear 801.

[0082] The spiral groove 806 and the vertical groove 805 are formed on the outer wall of the fixed rod 802, and one end of the vertical groove 805 is connected to one end of the spiral groove 806.

[0083] The rotating assembly 8 also includes: a spiral groove 806 and a ball bearing 807;

[0084] The spiral groove 806 is formed at the connection position between the movable seat 803 and the fixed rod 802. The ball 807 is rotatably connected to the inside of the movable seat 803 and extends through the inner cavity of the spiral groove 806. The ball 807 meshes with the spiral groove 806 and the vertical groove 805.

[0085] The top cover 101 has a groove for accommodating the rotation of the fixed gear 801.

[0086] In this embodiment: when the rotating plate 501 moves upward, the rotating plate 501 drives the moving seat 803 to move upward. The ball bearing 807 inside the moving seat 803 moves upward in the vertical groove 805. At the same time, the moving component 10 unlocks the locking component 9. After that, the ball bearing 807 moves to the junction of the vertical groove 805 and the spiral groove 806 and continues to move upward. At this time, the ball bearing 807 applies a squeezing force to the spiral groove 806, so that the fixed rod 802 rotates. The rotation of the fixed rod 802 drives the fixed gear 801 to rotate. The fixed gear 801 drives the horizontal rack 804 to move. The horizontal rack 804 drives the sliding cover 102 to move towards the receiving groove 106, so as to open the sliding cover 102 while the trash can is rising.

[0087] Please refer to the diagram carefully. Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 12The moving component 10 includes a slide rail 1001, a pressing rod 1002, a pulling bar 1003, a sliding sleeve 1004, and a return spring 1005;

[0088] A hollow slide rail 1001 is fixedly connected to the outside of a guide rail 7. A pressing rod 1002 is horizontally slidably connected to the slide rail 1001. A return spring 1005 is installed in the inner cavity of the slide rail 1001, and the two ends of the return spring 1005 are fixedly connected to the slide rail 1001 and the pressing rod 1002 respectively.

[0089] The pull bar 1003 is fixedly connected to one side of the top end of the extrusion rod 1002 and is set perpendicular to the extrusion rod 1002;

[0090] The sliding sleeve 1004 is fixedly connected to the other end of the bottom rod 409, and the sliding sleeve 1004 is slidably connected to the outer wall of the slide rail 1001. The bottom end of the extrusion rod 1002 is formed with a guide surface 1006.

[0091] In this embodiment: before the ball bearing 807 moves to the junction of the vertical groove 805 and the spiral groove 806, the sliding sleeve 1004 moves upward synchronously under the drive of the bottom rod 409. When the bottom rod 409 moves upward, it squeezes the guide surface 1006. The guide surface 1006 is forced to drive the squeezing rod 1002 to retract into the slide rail 1001, and at the same time squeezes the return spring 1005. The moving squeezing rod 1002 drives the pull bar 1003 to move, thereby squeezing the locking component 9. Since the sliding sleeve 1004 always resets the squeezing rod 1002 during the upward movement, the locking component 9 can be kept unlocked after unlocking.

The lock pin 903 that resets upward is used for the sliding cover 102, and the lock pin 903 that moves downward is used to release the limit on the sliding cover 102.

[0095] A groove is formed in the middle of the locking pin 903, and an extrusion surface 904 is formed on the wall of the groove;

[0096] The extrusion block 905 is integrally formed on the end face of the pull bar 1003, and the side of the extrusion block 905 near the extrusion surface 904 is formed with an inclined surface that matches the extrusion surface 904.

A protrusion 907 is formed at the bottom end of the lock post 903 and the protrusion 907 has an elliptical structure. The non-open end of the lock hole 901 located inside the side plate 104 matches the outer wall of the protrusion 907.

[0098] In this embodiment: During the movement of the pull bar 1003, the pull bar 1003 drives the pressing block 905 to move synchronously. At this time, the inclined surface on the pressing block 905 no longer presses the pressing surface 904. At this time, the locking pin 903 loses the pressing force, the pressing spring 906 begins to reset, and pulls the protrusion 907. The protrusion 907 drives the locking pin 903 to move downward until the locking pin 903 is completely separated from the locking hole 901 inside the sliding cover 102. At this time, the locking assembly 9 releases the locking of the sliding cover 102.

[0099] Please refer to this carefully. Figure 9 and 11 The clamping assembly 6 includes: a rotating gear 601, a vertical rack 602, a bidirectional stud 603, a connecting rod 604, a sliding seat 605, a fixing plate 606, a limiting post 607, a spring 608, and a pressing plate 609.

[0100] The connecting rod 604 is fixedly connected to the bottom end of the vertical plate 505. The two sliding seats 605 are horizontally slidably connected to the inner cavity of the connecting rod 604. The bidirectional stud 603 is rotatably connected to the inner wall of the connecting rod 604 and threadedly connected to the two sliding seats 605. One end of the bidirectional stud 603 extends to the outside of the connecting rod 604, and the rotating gear 601 is assembled at this end. The vertical rack 602 is integrally formed on the inner side of another guide rail 7, and the vertical rack 602 meshes with the rotating gear 601.

[0101] The fixed plate 606 is fixedly connected to one end of the sliding seat 605, the limiting post 607 is slidably connected to the inside of the fixed plate 606, the pressing plate 609 is fixedly connected to the end of the limiting post 607, the spring 608 is sleeved on the outer wall of the limiting post 607, and the two ends of the spring 608 are fixedly connected to the fixed plate 606 and the pressing plate 609 respectively.

[0102] In this embodiment: when the rotating plate assembly 5 moves upward, the clamping assembly 6 moves upward accordingly. At this time, the rotating gear 601 meshes with the vertical rack 602, and the vertical rack 602 remains fixed. Therefore, the rotating gear 601 rotates, driving the bidirectional stud 603 to rotate. The surface of the bidirectional stud 603 is formed with positive and negative threads. The positive thread is threaded to one sliding seat 605, and the negative thread is threaded to the other sliding seat 605. At this time, the bidirectional stud 603 can drive the two sliding seats 605 to rotate along the connecting... The inner cavity of the connecting rod 604 moves towards each other, gradually approaching the outer wall of the trash can during the movement, until the squeezing plate 609 is in close contact with the outer wall of the trash can. If the rotating gear 601 has not yet separated from the vertical rack 602 at this time, the sliding seat 605 continues to move, driving the fixed plate 606 to continue moving. At this time, the limiting post 607 remains stationary, and the fixed plate 606 slides along the surface of the limiting post 607 and squeezes the spring 608 until the rotating gear 601 separates from the vertical rack 602, thus completing the purpose of clamping the trash can.

[0103] The above description is merely a preferred embodiment of the present invention, but 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 inventive concept of the present invention, should be covered within the scope of protection of the present invention.
