Description

Technical Field

[0001] The present invention relates to the technical field of garbage transfer devices, and in particular to a garbage transfer vehicle in a garbage transfer station based on gravity perception. Background Art

[0002] In the urban waste treatment system, waste transfer stations play a vital role. They are responsible for receiving, temporarily storing and transferring waste from various collection points to provide support for the subsequent waste treatment process. However, there are some design deficiencies in the transfer vehicles in traditional waste transfer stations, especially when handling shredded waste. These problems are particularly prominent.

[0003] The variety of shapes and densities of crushed garbage poses a challenge to the storage mechanism of the transfer vehicle. On the one hand, for crushed garbage with a higher density, the transfer vehicle may quickly reach its upper limit of carrying capacity and need to carry out transportation operations frequently, which not only reduces the transfer efficiency but also increases the operating cost. On the other hand, for crushed garbage with a lower density, due to its large volume, it is easy to pile up too high in the storage mechanism, resulting in the transfer vehicle being unable to continue to accept new garbage, and may even cause safety hazards.

[0004] In order to solve these problems, some improved transfer vehicles for garbage transfer stations have appeared on the market, but most of them only focus on improving transfer efficiency or increasing storage capacity, while ignoring the impact of garbage form and density on the transfer process. For example, although some transfer vehicles have increased the volume of the storage mechanism, they are still prone to over-pile when facing low-density crushed garbage; and although other transfer vehicles are equipped with advanced control systems, due to the lack of real-time monitoring and dynamic adjustment mechanism of garbage weight, it is still difficult to achieve efficient transfer while ensuring safety. Summary of the invention

[0005] The present invention provides a gravity-sensing in-station transfer vehicle for garbage transfer stations, so as to solve the problem that the existing devices are inconvenient to adaptively adjust the volume according to the density of the transported crushed garbage.

[0006] In order to alleviate the above technical problems, the technical solution provided by the present invention is:

[0007] A gravity-sensing in-station transfer vehicle for garbage transfer stations, comprising a material storage mechanism, wherein the material storage mechanism comprises a bottom plate, an upper surface of the bottom plate is connected to a first box body, and an outer portion of the first box body is slidably connected to a second box body;

[0008] A gravity sensor is provided on the bottom wall of the first box body, and a position sensor is provided at the port of the second box body;

[0009] When the position sensor detects that the accumulated height of the shredded garbage is close to the opening of the first box body, and the gravity sensor detects that the weight of the shredded garbage does not reach the bearing capacity of the first box body, the second box body moves upward relative to the first box body, thereby increasing the material storage space of the transport device, and,

[0010] When the gravity sensor detects that the weight of the shredded garbage reaches the bearing capacity of the first box, the transport device operates to transfer the shredded garbage.

[0011] Furthermore, it also includes a flattening mechanism, which includes a vibration plate that linearly slides on the bottom of the first box body, a rotating disk that rotates on a fixed axis at the bottom of the vibration plate, an eccentric rod connected to the upper surface of the rotating disk, a hollow bar connected to the lower surface of the vibration plate, and the eccentric rod sliding on the hollow bar;

[0012] When the rotating disk rotates, the eccentric rod slides back and forth in the hollow bar, so that the vibration plate slides back and forth in the first box body.

[0013] Furthermore, it also includes a capacity sensing mechanism, which includes two slides that slide symmetrically at the opening of the second box body, a feeding port is commonly provided in the middle of the two slides, and an inclined surface is provided on the upper surface of the two slides, and the bottom of the inclined surface faces the feeding port;

[0014] The two slide plates are symmetrically arranged in the sliding direction of the vibration plate, and when the vibration plate slides back and forth, the slide plate located on the opposite side of the sliding direction of the vibration plate slides in the opposite direction synchronously and equidistantly with the vibration plate;

[0015] After the stacking height of the crushed garbage in the first box body increases, the reciprocating movement of the two slide plates can clamp the crushed garbage, thereby sensing that the crushed garbage in the first box body is full.

[0016] Furthermore, the capacity sensing mechanism further comprises two groups of first piston cylinders symmetrically connected to both sides of the bottom plate and two groups of first piston rods sliding in the corresponding first piston cylinders, and two groups of first hydraulic rods are symmetrically connected to the outer wall of the second box body, and the output ends of the two groups of first hydraulic rods are respectively connected to the two slide plates;

[0017] The first piston cylinder is connected to the first hydraulic rod on the opposite side via a first oil pipe;

[0018] The vibration plate is magnetically attracted to the first piston rod. When the vibration plate slides back and forth, the first piston rod can drive the first hydraulic rod on the opposite side to extend and retract, so that the slide plate on the opposite side of the sliding direction of the vibration plate slides in opposite directions synchronously and equidistantly with the vibration plate.

[0019] Furthermore, it also includes a lifting mechanism, which includes a second hydraulic rod, and the cylinder body and cylinder rod of the second hydraulic rod are respectively connected to the second box body and the bottom plate. When the second hydraulic rod is extended, the second box body can move upward relative to the first box body to increase the capacity of the transportation device.

[0020] Furthermore, the lifting mechanism further comprises a connecting seat and an L-shaped seat, the connecting seat is connected to the second box body, and the cylinder rod and the cylinder body of the first hydraulic rod are respectively connected to the L-shaped seat and the second box body;

[0022] When there is crushed garbage between the two slides, the contraction of the first hydraulic rod can drive the cylindrical rod to slide into the cylindrical cavity, so that the hydraulic oil in the cylindrical cavity is transferred to the second hydraulic rod to make the second box body move upward relative to the first box body.

[0023] Furthermore, it also includes a moving mechanism, the moving mechanism includes a wheel seat, the wheel seat slides on the bottom plate, and the wheel seat is connected to a moving wheel;

[0024] When the second box body moves upward relative to the first box body, the wheel seat slides synchronously in a direction away from the bottom plate.

[0025] Furthermore, the moving mechanism further comprises a sliding block connected to the wheel seat, and a sliding groove cooperating with the sliding block is provided in the bottom plate;

[0026] The slide groove is located on one side of the sliding block and is filled with hydraulic oil, and the pumping tube is connected to the slide groove, so that the cylindrical cavity can extract the hydraulic oil in the slide groove to make the wheel seat slide in a direction away from the bottom plate.

[0027] Furthermore, it also includes a stabilizing mechanism, the stabilizing mechanism includes a rectangular block, and the rectangular block slides vertically on the lower surface of the bottom plate;

[0028] When the vibration plate reciprocates, the rectangular block moves downward and contacts the ground, and when the vibration plate stops moving, the rectangular block moves upward and away from the ground.

[0029] Furthermore, an electric telescopic rod is connected between the rectangular block and the bottom plate.

[0030] The beneficial effects of the present invention are analyzed as follows:

[0031] A gravity-sensing based on-site transfer vehicle of a garbage transfer station comprises a material storage mechanism, the material storage mechanism comprises a bottom plate, the upper surface of the bottom plate is connected to a first box body, and the outside of the first box body is slidably connected to a second box body; a gravity sensor is provided on the bottom wall of the first box body, and a position sensor is provided at the port of the second box body; when the position sensor detects that the accumulation height of shredded garbage is close to the opening of the first box body, and when the gravity sensor detects that the weight of the shredded garbage does not reach the bearing capacity of the first box body, the second box body moves up relative to the first box body, thereby increasing the material storage space of the transportation device, and when the gravity sensor detects that the weight of the shredded garbage reaches the bearing capacity of the first box body, the transportation device operates to transfer the shredded garbage.

[0032] The storage mechanism is placed at the discharge point of the shredded garbage to receive the shredded garbage, and the shredded garbage falls into the first box body. The gravity sensor arranged at the bottom of the first box body detects the weight of the shredded garbage. When the gravity of the shredded garbage reaches the carrying capacity of the transportation device, the transportation device stops receiving the shredded garbage and then transports the shredded garbage. When the shredded garbage with lower density is transported, the height of the shredded garbage accumulation gradually increases. At this time, the position sensor at the port of the second box body detects the height of the shredded garbage. When the position sensor detects that the height of the shredded garbage reaches the port of the first box body, the second box body moves up relative to the first box body, so that the total volume of the inner cavity of the second box body and the first box body increases, thereby enabling the transportation device to accommodate more low-density shredded garbage. When the upward movement height of the second box body reaches the highest point of the stroke, the transportation device stops receiving the shredded garbage and then transports the shredded garbage. The device improves the transportation efficiency and ensures the safety and stability of the transportation process. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] Example

[0048] like Figure 1-Figure 8 As shown, a gravity-sensing in-station transfer vehicle for garbage transfer stations includes a storage mechanism 100, which includes a bottom plate 110, the upper surface of the bottom plate 110 is connected to a first box body 120, and the outside of the first box body 120 is slidably connected to a second box body 130; a gravity sensor is provided on the bottom wall of the first box body 120, and a position sensor is provided at the port of the second box body 130; the position sensor detects that the accumulation height of the shredded garbage is close to the opening of the first box body 120, and when the gravity sensor detects that the weight of the shredded garbage does not reach the bearing capacity of the first box body 120, the second box body 130 moves up relative to the first box body 120, thereby increasing the material storage space of the transportation device, and when the gravity sensor detects that the weight of the shredded garbage reaches the bearing capacity of the first box body 120, the transportation device operates to transfer the shredded garbage.

[0049] The working mechanism of the crushed garbage transportation device provided in this embodiment is as follows:

[0050] The storage mechanism 100 is placed at the discharge point of the shredded garbage to receive the shredded garbage, and the shredded garbage falls into the first box body 120. The gravity sensor arranged at the bottom of the first box body 120 detects the weight of the shredded garbage. When the gravity of the shredded garbage reaches the carrying capacity of the transportation device, the transportation device stops receiving the shredded garbage and then transports the shredded garbage. When the shredded garbage with lower density is transported, the height of the shredded garbage accumulation gradually increases. At this time, the position sensor at the port of the second box body 130 detects the height of the shredded garbage. When the position sensor detects that the height of the shredded garbage reaches the port of the first box body 120, the second box body 130 moves up relative to the first box body 120, so that the total volume of the inner cavity of the second box body 130 and the first box body 120 increases, so that the transportation device can accommodate more low-density shredded garbage. When the upward movement height of the second box body 130 reaches the highest point of the stroke, the transportation device stops receiving the shredded garbage and then transports the shredded garbage.

[0051] Regarding the structure of the flattening mechanism 200, specifically:

[0052] The flattening mechanism 200 includes a vibration plate 210 that slides linearly at the bottom of the first box body 120, and a turntable 230 is located at the bottom of the vibration plate 210 and rotates on a fixed axis. The upper surface of the turntable 230 is connected to an eccentric rod 240, and the lower surface of the vibration plate 210 is connected to a hollow bar 220, and the eccentric rod 240 slides in the hollow bar 220; when the turntable 230 rotates, the eccentric rod 240 slides back and forth in the hollow bar 220, so that the vibration plate 210 slides back and forth in the first box body 120.

[0053] When receiving the crushed garbage, in order to prevent the crushed garbage from piling up in the middle of the first box body 120, it is necessary to start the vibration plate 210 to vibrate the crushed garbage in the first box body 120 so that the crushed garbage is evenly distributed in the first box body 120. The turntable 230 is driven to rotate by a motor. At this time, the eccentric rod 240 on the turntable 230 slides back and forth in the hollow bar 220, so that the vibration plate 210 slides back and forth at the bottom of the first box body 120, so that the crushed garbage dropped into the first box body 120 is vibrated and flattened, so that the crushed garbage is evenly distributed in the first box body 120.

[0054] Regarding the structure of the capacity sensing mechanism 300, specifically:

[0055] The capacity sensing mechanism 300 includes two slide plates 350 that slide symmetrically at the opening of the second box body 130, and a discharge port 360 is commonly provided in the middle of the two slide plates 350, and the upper surfaces of the two slide plates 350 are provided with inclined surfaces, and the bottom of the inclined surfaces face the discharge port 360; the two slide plates 350 are symmetrically arranged in the sliding direction of the vibration plate 210, and when the vibration plate 210 slides back and forth, the slide plate 350 located on the opposite side of the sliding direction of the vibration plate 210 slides synchronously and equidistantly in the opposite direction with the vibration plate 210; after the stacking height of the crushed garbage in the first box body 120 increases, the reciprocating movement of the two slide plates 350 can clamp the crushed garbage, thereby sensing that the crushed garbage in the first box body 120 is full.

[0056] Two slide plates 350 are symmetrically slidably connected at the upper end of the second box body 130. A discharge port 360 formed in the middle of the two slide plates 350 allows the crushed garbage to enter the box body, and the inclined surface set on the slide plate 350 allows the crushed garbage to slide along the slope to the discharge port 360. When the vibration plate 210 slides back and forth, the slide plate 350 located on the opposite side of the vibration plate 210 slides synchronously and equidistantly in the opposite direction away from the vibration plate 210, thereby balancing the offset force generated by the vibration plate 210 when sliding on the device, and the slide plate 350 slides When it moves, the crushed garbage falling on its inclined surface can be vibrated and moved to the discharge port 360. Among the two slides 350, only the side opposite to the vibration plate 210 slides synchronously, and the slide 350 on the sliding side does not move. When the crushed garbage in the first box body 120 accumulates to the opening of the second box body 130, the crushed garbage will be between the two slides 350 at this time. Therefore, the sliding of the slide 350 makes the crushed garbage be squeezed and clamped by the two slides 350. At this time, the crushed garbage in the first box body 120 is already full.

[0057] Among the optional methods of this embodiment, the more preferred ones are:

[0058] The capacity sensing mechanism 300 also includes two groups of first piston cylinders 310 symmetrically connected to both sides of the bottom plate 110 and two groups of first piston rods 320 sliding in the corresponding first piston cylinders 310. Two groups of first hydraulic rods 340 are symmetrically connected to the outer wall of the second box body 130, and the output ends of the two groups of first hydraulic rods 340 are respectively connected to two slide plates 350; the first piston cylinder 310 and the first hydraulic rod 340 on the opposite side are connected by a first oil pipe 330; the vibration plate 210 and the first piston rod 320 are magnetically attracted to each other, and when the vibration plate 210 slides back and forth, the first piston rod 320 can drive the first hydraulic rod 340 on the opposite side to extend and retract, so that the slide plate 350 located on the opposite side of the sliding direction of the vibration plate 210 slides synchronously and equidistantly in the opposite direction with the vibration plate 210.

[0059] When the vibration plate 210 slides, the vibration plate 210 can squeeze the first piston rod 320 on its sliding side, so that the first piston rod 320 slides into the corresponding first piston cylinder 310, so that the hydraulic oil in the first piston cylinder 310 is transmitted to the first hydraulic rod 340 on the opposite side through the first oil pipe 330. At this time, the first hydraulic rod 340 extends, so that the first hydraulic rod 340 pushes the capacity sensing mechanism 300 on the opposite side of the vibration plate 210 to slide, and there is magnetic attraction between the vibration plate 210 and the first piston rod 320, so that when the vibration plate 210 is away from the first piston rod 320, the first piston rod 320 can pull the first piston cylinder 310.

[0060] Regarding the structure of the lifting mechanism 400, specifically:

[0061] The lifting mechanism 400 includes a second hydraulic rod 410, a cylinder body and a cylinder rod of the second hydraulic rod 410 are respectively connected to the second box 130 and the bottom plate 110. When the second hydraulic rod 410 is extended, the second box 130 can move upward relative to the first box 120 to increase the capacity of the transport device.

[0062] When the crushed garbage is accumulated at the end of the second box body 130, the second hydraulic rod 410 extends, and at this time the second hydraulic rod 410 pushes the second box body 130 to move upward relative to the first box body 120, thereby increasing the volume of the transportation device.

[0063] Among the optional methods of this embodiment, the more preferred ones are:

[0064] The lifting mechanism 400 further includes a connecting seat 421 and an L-shaped seat 423. The connecting seat 421 is connected to the second box body 130. The cylinder rod and the cylinder body of the first hydraulic rod 340 are respectively connected to the L-shaped seat 423 and the second box body 130. The L-shaped seat 423 is connected to a cylindrical rod 424. A cylindrical cavity 422 matching the cylindrical rod 424 is provided in the connecting seat 421. A liquid extraction pipe 430 and a liquid discharge pipe 440 communicating with the cylindrical cavity 422 are connected to the connecting seat 421. The liquid pipe 440 is connected to the second hydraulic rod 410, and a spring 420 is sleeved on the cylindrical rod 424. The two ends of the spring 420 are fixedly connected to the L-shaped seat 423 and the connecting seat 421 respectively; when there is crushed garbage between the two slides 350, the contraction of the first hydraulic rod 340 can drive the cylindrical rod 424 to slide into the cylindrical cavity 422, so that the hydraulic oil in the cylindrical cavity 422 is transferred to the second hydraulic rod 410 to make the second box body 130 move up relative to the first box body 120.

[0065] When the first hydraulic rod 340 is extended or retracted, the first hydraulic rod 340 drives the slide plate 350 to slide through the connecting seat 421 and the L-shaped seat 423. When there is crushed garbage between the two slide plates 350, the two slide plates 350 approach each other, which causes the connecting seat 421 and the L-shaped seat 423 to slide relative to each other, so that the cylindrical rod 424 slides into the cylindrical cavity 422. At this time, the hydraulic rod in the cylindrical cavity 422 can be transmitted to the second hydraulic rod 410 through the drain pipe 440, so that the second hydraulic rod 410 is extended, so that the second box body 130 moves upward relative to the first box body 120.

[0066] The setting of the spring 420 allows the cylindrical rod 424 to reset when it slides into the cylindrical cavity 422, and also allows the two slide plates 350 to stably contact each other when there is no crushed garbage. When the cylindrical rod 424 resets, the cylindrical cavity 422 can extract hydraulic oil through the suction pipe 430, which is convenient for the subsequent continuous supply of hydraulic oil to the second hydraulic rod 410, so that the second hydraulic rod 410 can continue to extend. The drainage pipes 440 on both sides of the second box body 130 are simultaneously connected to the second hydraulic rods 410 on both sides, that is, the hydraulic oil discharged from a group of drainage pipes 440 on one side can be supplied to the two second hydraulic rods 410, and combined with the setting of the diverter valve, the two second hydraulic rods 410 can extend an equal distance.

[0067] Regarding the structure of the moving mechanism 500, specifically:

[0068] The moving mechanism 500 includes a wheel seat 510 , which slides on the bottom plate 110 , and a moving wheel 520 is connected to the wheel seat 510 ; when the second box body 130 moves upward relative to the first box body 120 , the wheel seat 510 synchronously slides in a direction away from the bottom plate 110 .

[0069] When the second box body 130 moves upward relative to the first box body 120, in order to enhance the stability of the device during movement, the wheel seat 510 connected to the bottom plate 110 slides relative to the bottom plate 110 and moves the moving wheel 520 away from the bottom plate 110, thereby enhancing the overall supporting force of the transportation device and enhancing the movement stability of the transportation device.

[0070] Among the optional methods of this embodiment, the more preferred ones are:

[0071] The moving mechanism 500 also includes a slider 530 connected to the wheel seat 510, and a slide groove 540 cooperating with the slider 530 is opened in the base plate 110; the slide groove 540 is located on one side of the slider 530 and is filled with hydraulic oil, and the suction tube 430 is connected to the slide groove 540, so that the cylindrical cavity 422 can extract the hydraulic oil in the slide groove 540 to make the wheel seat 510 slide in a direction away from the base plate 110.

[0072] The slide grooves 540 are interconnected and connected to the four liquid extraction pipes 430 through the diverter valve, that is, the cylindrical cavity 422 on the same side can extract an equal amount of hydraulic oil from the four slide grooves 540, so that the slider 530 slides an equal distance in the corresponding slide groove 540, and the hydraulic oil in the slide groove 540 is transferred to the second hydraulic rod 410, so that the extension of the second hydraulic rod 410 is synchronized with the movement of the wheel seat 510, so that when the second box body 130 moves up, no matter where the second box body 130 moves up within its stroke, the wheel seat 510 can move synchronously to provide a stable support force for the transportation device.

[0073] Regarding the structure of the stabilizing mechanism 600, specifically;

[0074] The stabilizing mechanism 600 includes a rectangular block 610 that slides vertically on the lower surface of the bottom plate 110; when the vibration plate 210 reciprocates, the rectangular block 610 moves down and contacts the ground, and when the vibration plate 210 stops moving, the rectangular block 610 moves up and away from the ground.

[0075] When the transport device receives the crushed garbage, the rectangular block 610 moves down to contact the ground, and the transport device moves up as a whole, thereby increasing the contact area between the transport device and the ground, and the moving wheel 520 does not contact the ground at this time, thereby improving the stability of the transport device when receiving the crushed garbage, and ensuring that the movement of the wheel seat 510 is not affected by the resistance of the ground.

[0076] Among the optional methods of this embodiment, the more preferred ones are:

[0077] An electric telescopic rod 620 is connected between the rectangular block 610 and the bottom plate 110 .

[0078] The extension and retraction of the electric telescopic rod 620 can drive the rectangular block 610 to move up and down, so that the transport device can be fixed and released. The electric telescopic rod 620 extends when the transport device reaches the place where the crushed garbage is received. After the transport device is fully loaded with crushed garbage, the electric telescopic rod 620 shortens, so that the transport device can move to transport the crushed garbage.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
