Description

Technical Field

[0001] This invention relates to the field of kitchen waste truck technology, specifically to an automatic kitchen waste truck for loading and unloading waste and its operating method. Background Technology

[0002] Food waste trucks are specialized vehicles used to collect and transport household waste, food waste, and urban sludge. Existing food waste trucks can automatically lift and empty household waste bins, and can automatically load and unload waste when the amount of waste in the food waste truck reaches a certain level.

[0003] Household waste bins contain a wide variety of types of garbage, and sometimes the garbage accumulates in the bins, making them difficult to empty. To solve this problem, existing food waste trucks are designed with a shaking mechanism. When the garbage bin is lifted and tilted to the garbage dumping position, the shaking mechanism shakes the garbage bin to help the garbage inside fall downwards. However, this method of assisting in emptying garbage can cause significant damage to the garbage bin, making it prone to breakage. At the same time, some tightly packed garbage is difficult to be dumped by shaking, resulting in poor garbage disposal efficiency. Summary of the Invention

[0004] To address the problems of existing food waste trucks that rely on a shaking mechanism to wiggle the garbage bin and assist in the downward dumping of waste, which can cause significant damage to the bin and makes it difficult to empty tightly packed garbage, resulting in inefficient dumping, this invention provides the following technical solution: an automatic food waste truck for loading and unloading, comprising a frame, a garbage bin, and a disposal opening. A jack is installed at the bottom of the frame, and the bottom of the garbage bin at the dumping end is rotatably connected to the rear of the frame. The jack automatically tilts the garbage bin, achieving automatic unloading of the waste. This part utilizes existing technology and is not shown in the attached drawings. The side of the garbage bin... A lifting support is installed opposite the disposal opening. The lifting support adopts existing technology and is not specifically shown in the attached figure. The lifting support can realize the lifting and tipping operation of the garbage can. The garbage can containing garbage is lifted upward to the disposal opening position using the lifting support. Then the garbage can is tipped so that the opening of the garbage can faces downward and corresponds to the disposal opening. At this time, the garbage can can be emptied. The garbage can is equipped with two sets of lifting rods inside. The upper end of each set of lifting rods is fixedly installed with an L-shaped adjustment frame. The surface of the adjustment frame is equipped with a mounting frame. The tilt angle of the mounting frame in the vertical direction is adjusted using the adjustment frame. The lifting rod is a hydraulic rod. The height of the mounting frame can be adjusted using the lifting rod, so that the spiked roller in the mounting frame can be pushed into the garbage can at the disposal opening.

[0005] Several spiked rollers are provided between the two sets of mounting frames. The spiked rollers are vertically aligned with the disposal opening. When the trash can is placed with the opening facing downwards at the disposal opening, the tilt angle of the mounting frame relative to the horizontal plane is adjusted, and the lifting rod is used to push the spiked rollers into the trash can. The rotation of the spiked rollers is used to discharge and clean the trash in the trash can.

[0006] Furthermore, a guide block one is rotatably mounted on the lower surface of the mounting frame, and a guide block two is rotatably mounted on the surface of the mounting frame near the vertical rod of the adjusting frame. The guide block one is horizontally slidably mounted on the upper surface of the horizontal rod of the adjusting frame, and the guide block two is vertically slidably mounted on the surface of the vertical rod of the adjusting frame.

[0007] A second hydraulic rod is installed inside the horizontal bar of the adjusting frame, and the telescopic end of the second hydraulic rod is fixedly connected to the first guide block.

[0008] The angle between the mounting bracket and the axis of the second hydraulic rod is greater than 0°, so that the second hydraulic rod can drive the first guide block to move.

[0009] Hydraulic rod 2 drives guide block 1 to slide horizontally. Guide block 1 will drive the end of the mounting frame away from the adjustment frame to slide horizontally. At the same time, guide block 2 will slide up and down on the surface of the vertical rod, thereby realizing the adjustment of the tilt angle of the mounting frame. At the same time, it ensures that the spiked roller on the side of the mounting frame closest to the vertical rod is in the same vertical direction, so that the spiked roller can enter the garbage can from the position close to the inner wall of the garbage can.

[0010] The different tilt angles of the mounting frame affect the effectiveness of the multiple spiked rollers in discharging garbage from the bin. The larger the angle between the mounting frame and the horizontal plane, the more vertical the spiked rollers become, resulting in less contact and squeezing force between the rollers and the garbage inside the bin, and a poorer effect of actively discharging garbage. However, the rollers also reduce resistance to the falling garbage. Conversely, the smaller the angle between the mounting frame and the horizontal plane, the greater the contact and squeezing force between the rollers and the garbage inside the bin, and a better effect of actively discharging garbage. However, the rollers also increase resistance to the falling garbage.

[0011] When the trash inside the bin is prone to falling due to gravity, or when the trash inside the bin is not tightly packed, the angle between the mounting bracket and the horizontal plane should be appropriately increased; when the trash inside the bin is not prone to falling due to gravity, or when the trash inside the bin is tightly packed, the angle between the mounting bracket and the horizontal plane should be appropriately decreased.

[0012] Furthermore, several of the spiked rollers are rotatably connected to the mounting frame via shafts, and several rows of conical spikes are circumferentially mounted on the surface of the spiked rollers. The design of the spikes can increase the effect of the spiked rollers actively conveying garbage inside the trash can.

[0013] The surface of each shaft is provided with a transmission gear, and the transmission gears at the same end of several of the licker rollers are synchronously connected by a toothed belt. A motor is installed on the side surface of the mounting frame, and the motor drives the shaft on the side of the mounting frame away from the adjusting frame to rotate.

[0014] The shafts of the two spiked rollers at both ends of the mounting frame are fixedly connected to the transmission gear, and friction rings are fixedly installed on the shaft surfaces of the remaining spiked rollers. The outer ring surface of the friction rings is in frictional contact with the inner ring surface of the transmission gear.

[0015] When bagged garbage inside the trash can causes a blockage in the garbage conveying process, the rotation of the spiked rollers may be obstructed. When one or more spiked rollers between the two spiked rollers at both ends of the mounting frame experience significant obstruction, the friction ring on the shaft surface of that spiked roller rotates relative to the transmission gear, and the spiked roller stops rotating. A speed difference will occur between that spiked roller and the adjacent spiked rollers. When the speeds of two or more spiked rollers are not synchronized, the bagged garbage is easily torn apart by the action of the spikes, thereby dispersing the garbage and preventing blockage, thus facilitating the conveying of garbage inside the trash can.

[0016] Furthermore, two sets of hydraulic rods are installed on the top surface inside the garbage bin. The lower end of each hydraulic rod is fixedly installed with a support plate. The two sets of lifting rods are respectively fixedly installed on the upper surfaces of the two sets of support plates. The design of the hydraulic rods and support plates can increase the upward stroke of the mounting frame. At the same time, the mounting frame can be adjusted upward to prevent it from affecting the tilting of the garbage inside the garbage bin when unloading garbage.

[0017] Furthermore, the inside of the garbage bin is provided with two sets of transverse screws and two sets of scrapers. The two sets of transverse screws and the two sets of scrapers are respectively distributed on both sides of the width direction inside the garbage bin. Each set of transverse screws includes transverse screw one and transverse screw two, and each set of scrapers includes scraper one and scraper two. Both scraper one and scraper two are rake-shaped.

[0018] The first and second transverse screws are arranged in parallel. A connecting block is rotatably installed at the end of the first scraper away from the second scraper. The connecting block is threaded to the surface of the first transverse screw. A connecting block is rotatably installed at the end of the second scraper away from the first scraper. The connecting block is threaded to the surface of the second transverse screw. The adjacent ends of the first and second scrapers are rotatably connected by an adapter.

[0019] When scraper blades 1 and 2 in the same group are arranged in a straight line or a V-shape, scraper blades 1 and 2 work together to flatten the garbage inside the garbage bin in the width direction, which helps to improve the utilization rate of the garbage bin's internal space.

[0020] In the two sets of scrapers, a connecting telescopic rod is provided inside the end face of one set of scrapers near the other scraper, and a connecting hole is opened on the end face of the other set of scrapers near the other scraper. When the two sets of scrapers are rotated to the same vertical plane, the connecting telescopic rod can be inserted into the connecting hole. The connecting telescopic rod is a hydraulic rod.

[0021] By using horizontal screw one and horizontal screw two to cooperate with connecting block one and connecting block two respectively, scraper one and scraper two in the same group are stacked together, and scraper one in both groups is located in the same vertical plane. Then, the connecting telescopic rod is activated, so that the connecting telescopic rod is inserted into the corresponding connecting hole. At this time, scraper one in both groups is connected together, which can be used to level the garbage inside the garbage can along the length of the garbage can.

[0022] Alternatively, a connecting telescopic rod can be provided on the end face of one of the two sets of scrapers near the side of scraper one, and a connecting hole can be provided on the end face of the other set of scrapers near the side of scraper two. The connecting telescopic rod in the two sets of scrapers cooperates with the connecting hole, which can improve the strength of the combined connection of the two sets of scrapers.

[0023] Furthermore, the inside of the trash can is equipped with two sets of vertical screws, and a motor module for driving the vertical screws to rotate is installed at the bottom of the trash can. The two sets of vertical screws are respectively distributed on both sides of the width direction inside the trash can. Each set of vertical screws has two vertical screws, and the two vertical screws in the same set are distributed at both ends of the horizontal screw in the same set.

[0024] The vertical screw is threadedly connected to a mounting base one. An adjusting telescopic rod is fixedly installed inside the mounting base one. The adjusting telescopic rod is a hydraulic rod. The adjusting telescopic rod is distributed along the width direction of the garbage bin. The telescopic end of the adjusting telescopic rod is fixedly installed with a mounting base two. The ends of the horizontal screw one and the horizontal screw two in the same group are rotatably connected to the mounting base two. A motor module for driving the horizontal screw one and the horizontal screw two to rotate is installed on the surface of the mounting base two.

[0025] By using the vertical screw and mounting base one, the position of the scraper can be adjusted up and down. The position of the scraper can be adjusted in the width direction of the garbage bin by using the adjusting telescopic rod. When scraper one and scraper two in the same group of scrapers are combined to form a V-shaped structure, the adjusting telescopic rod cooperates with scraper one and scraper two in the V-shaped structure to flatten the garbage inside the garbage bin in the width direction. This design can reduce the design stroke of the adjusting telescopic rod.

[0026] An automated method for loading and unloading food waste from a kitchen waste truck includes the following specific steps:

[0027] S. First, position the trash can with its opening facing downwards and align it with the disposal opening. Under the influence of gravity, some of the trash inside the trash can will fall downwards into the trash bin.

[0028] S. Activate the first hydraulic rod and the lifting rod to push the mounting frame upward, and activate the second hydraulic rod to tilt the mounting frame so that the spiked roller in the mounting frame can enter the garbage can from a position close to the inner wall of the garbage can;

[0029] S. Start the motor on the side surface of the mounting frame. The motor, in conjunction with the toothed belt and transmission gear, drives several spiked rollers to rotate. The spikes on the surface of the spiked rollers exert a pushing force on the waste. Through the cooperation of several spiked rollers, the waste is pushed downwards and discharged.

[0030] S. When the garbage inside the garbage bin is severely clogged, adjust the tilt angle of the mounting bracket. When one or more of the spiked rollers are significantly obstructed from rotating, a speed difference occurs between the obstructed spiked roller and the adjacent spiked roller. The speeds of the two or more spiked rollers are not synchronized. Under the combined action of the spikes, the garbage that is squeezed together is dispersed, further discharging the garbage inside the garbage bin.

[0031] Furthermore, it also includes:

[0032] S. After the garbage is put into the garbage bin, the vertical screw, the first horizontal screw, the second horizontal screw and the adjusting telescopic rod are used to flatten the garbage in the width direction of the garbage bin.

[0033] S. Adjust the positions of scraper one and scraper two using the first and second transverse screws, so that the two scraper one scrapers in the two sets of scrapers are adjusted to the same vertical plane. Then activate the connecting telescopic rod to insert the connecting telescopic rod into the corresponding connecting hole, so that the two sets of scrapers are connected together.

[0034] S. Using the first and second transverse screws, the two sets of scrapers are driven to move synchronously along the length of the garbage bin, and the garbage placed in the garbage bin is leveled in the width direction of the garbage bin.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] 1. The automatic garbage loading and unloading vehicle for kitchen waste and its operating method, by setting up a combination structure of lifting rod, adjusting frame and mounting frame and spiked roller below the disposal port, can use the rotation of spiked roller and control the tilt angle of the mounting frame to assist in the discharge of garbage inside the garbage bin without shaking the garbage bin. At the same time, the design of the spiked roller surface and the speed difference generated when multiple spiked rollers are obstructed can disperse the garbage or garbage bags squeezed together, preventing garbage from accumulating and clogging in the garbage bin, and the garbage discharge effect inside the garbage bin is good.

[0037] 2. The automatic loading and unloading garbage truck and its operating method, through the combination design of two sets of vertical screws, adjusting telescopic rods, horizontal screw one and horizontal screw two, and two sets of scraper one and scraper two, can flatten the garbage put into the garbage bin in the width and length directions, which is conducive to improving the utilization rate of the internal space of the garbage bin, thereby increasing the amount of garbage collected by the garbage bin.

[0049] 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.

[0050] The following is an embodiment of the automated food waste loading and unloading truck and its operating method:

[0051] Please see Figures 1-10 An automatic garbage loading and unloading vehicle for kitchen waste includes a frame, a garbage bin 1, and a disposal opening 101. A jack is installed at the bottom of the frame. The bottom of the garbage bin 1, the end where the garbage is dumped, is rotatably connected to the rear of the frame. The jack is used to automatically tip the garbage bin 1, thus automatically unloading the garbage inside. This part uses existing technology and is not shown in the attached drawings. A lifting bracket 2 is installed on the side of the garbage bin 1 opposite the disposal opening 101. The lifting bracket 2 also uses existing technology and is not specifically shown in the attached drawings. The lifting bracket 2 can lift the garbage bin and tip it over for dumping. The garbage bin containing garbage is lifted upwards to the position of the disposal opening 101 using the lifting bracket 2, and then the garbage bin is tipped so that the opening of the garbage bin faces downwards and aligns with the disposal opening 101, at which point the garbage can be dumped.

[0052] The inside of the garbage bin 1 is equipped with two sets of lifting rods 4. The upper end of each set of lifting rods 4 is fixedly installed with an L-shaped adjustment frame 41. The surface of the adjustment frame 41 is provided with a mounting frame 5. The tilt angle of the mounting frame 5 in the vertical direction can be adjusted by adjusting the adjustment frame 41. The lifting rods 4 are hydraulic rods. The height of the mounting frame 5 can be adjusted by using the lifting rods 4, so that the spiked roller 6 in the mounting frame 5 can be pushed into the garbage bin at the disposal port 101.

[0053] Two sets of hydraulic rods 3 are installed on the top surface inside the garbage bin 1. The lower end of the hydraulic rods 3 is fixedly installed with a support plate 31. Two sets of lifting rods 4 are respectively fixedly installed on the upper surface of the two sets of support plates 31. The design of the hydraulic rods 3 and the support plates 31 can increase the upward stroke of the mounting frame 5. At the same time, the mounting frame 5 can be adjusted upward to avoid affecting the tilting of the garbage inside the garbage bin 1 when unloading garbage.

[0054] Guide block 1 51 is rotatably mounted on the lower surface of mounting bracket 5, and guide block 2 52 is rotatably mounted on the surface of mounting bracket 5 near the vertical rod of adjusting bracket 41. Guide block 1 51 is horizontally slidably mounted on the upper surface of the horizontal rod of adjusting bracket 41, and guide block 2 52 is vertically slidably mounted on the surface of the vertical rod of adjusting bracket 41. Hydraulic rod 2 411 is installed inside the horizontal rod of adjusting bracket 41, and the telescopic end of hydraulic rod 2 411 is fixedly connected to guide block 1 51. The angle between the axis of mounting bracket 5 and the axis of hydraulic rod 2 411 is greater than 0°.

[0055] Hydraulic rod 411 drives guide block 51 to slide horizontally. Guide block 51 drives the end of the mounting frame 5 away from the adjusting frame 41 to slide horizontally. At the same time, guide block 52 slides up and down on the surface of the vertical rod, thereby realizing the adjustment of the tilt angle of the mounting frame 5. At the same time, it ensures that the spiked roller 6 closest to the vertical rod in the mounting frame 5 is in the same vertical direction, so that the spiked roller 6 can enter the garbage can from the position close to the inner wall of the garbage can.

[0056] The different tilt angles of the mounting frame 5 affect the effectiveness of the spiked rollers 6 in discharging garbage from the trash can. The larger the angle between the mounting frame 5 and the horizontal plane, the more vertical the spiked rollers 6 become, resulting in a smaller contact and squeezing force between the spiked rollers 6 and the garbage inside the trash can, and a worse effect on actively discharging garbage. However, the spiked rollers 6 also provide less resistance to the falling garbage. Conversely, the smaller the angle between the mounting frame 5 and the horizontal plane, the greater the contact and squeezing force between the spiked rollers 6 and the garbage inside the trash can, and a better effect on actively discharging garbage. However, the spiked rollers 6 also provide greater resistance to the falling garbage.

[0057] Several spiked rollers 6 are rotatably connected to the mounting frame 5 via shafts 62. Several rows of conical spikes 61 are installed circumferentially on the surface of the spiked rollers 6. The design of the spikes 61 can increase the effect of the spiked rollers 6 actively conveying garbage inside the garbage bin.

[0058] The surface of the shaft 62 is provided with transmission gears 71. The transmission gears 71 at the same end of several licker rollers 6 are synchronously connected by a toothed belt 7. A motor is installed on the side surface of the mounting frame 5, and the motor drives the shaft 62 on the side of the mounting frame 5 away from the adjusting frame 41 to rotate.

[0059] The shafts 62 of the two corresponding spiked rollers 6 at both ends of the mounting bracket 5 are fixedly connected to the transmission gear 71. Friction rings 621 are fixedly installed on the surface of the shafts 62 of the remaining spiked rollers 6. The outer ring surface of the friction rings 621 is in frictional contact with the inner ring surface of the transmission gear 71.

[0060] When bagged garbage inside the trash can causes a blockage in the garbage conveying process, the rotation of the spiked roller 6 may be obstructed. When one or more spiked rollers 6 between the two spiked rollers 6 at both ends of the mounting frame 5 are obstructed significantly, the friction ring 621 on the surface of the shaft 62 of the spiked roller 6 rotates relative to the transmission gear 71, and the spiked roller 6 stops rotating. A speed difference will occur between the spiked roller 6 and the adjacent spiked roller 6. When the speeds of the two or more spiked rollers 6 are not synchronized, the bagged garbage is easily torn by the action of the spikes 61, which can disperse the garbage, thereby preventing garbage blockage and facilitating the conveying of garbage inside the trash can.

[0061] When the trash inside the trash can is prone to falling under gravity, or when the trash inside the trash can is not tightly packed, the angle between the mounting frame 5 and the horizontal plane should be appropriately increased; when the trash inside the trash can is not prone to falling under gravity, or when the trash inside the trash can is tightly packed, the angle between the mounting frame 5 and the horizontal plane should be appropriately decreased.

[0062] Several spiked rollers 6 are provided between the two sets of mounting frames 5. The spiked rollers 6 correspond vertically to the disposal port 101. When the garbage can is placed with the opening facing downwards at the disposal port 101, the tilt angle of the mounting frame 5 relative to the horizontal plane is adjusted, and the lifting rod 4 is used to push the spiked rollers 6 into the garbage can. The rotation of the spiked rollers 6 is used to discharge and clean the garbage in the garbage can.

[0063] The garbage bin 1 is equipped with two sets of horizontal screws and two sets of scrapers. The two sets of horizontal screws and two sets of scrapers are distributed on both sides of the width direction inside the garbage bin 1. Each set of horizontal screws includes a horizontal screw 10 and a horizontal screw 2 12. Each set of scrapers includes a scraper 11 and a scraper 2 13. Both scraper 11 and scraper 2 13 are rake-shaped.

[0064] The first transverse screw 10 and the second transverse screw 12 are distributed in parallel. The end of the first scraper 11 away from the second scraper 13 is rotatably mounted with a connecting block 111. The connecting block 111 is threadedly connected to the surface of the first transverse screw 10. The end of the second scraper 13 away from the first scraper 11 is rotatably mounted with a connecting block 131. The connecting block 131 is threadedly connected to the surface of the second transverse screw 12. The adjacent ends of the first scraper 11 and the second scraper 13 are rotatably connected by an adapter 14.

[0065] When scraper blade 11 and scraper blade 23 in the same group are arranged in a straight line or a V-shape, scraper blade 11 and scraper blade 23 work together to flatten the garbage inside the garbage bin 1 in the width direction, which helps to improve the utilization rate of the internal space of the garbage bin 1.

[0066] In the two sets of scrapers, one set of scraper 11 has a connecting telescopic rod 15 inside the end face near scraper 2 13, and the other set of scraper 11 has a connecting hole on the end face near scraper 2 13. When the two sets of scraper 11 rotate to the same vertical plane, the connecting telescopic rod 15 can be inserted into the connecting hole. The connecting telescopic rod 15 is a hydraulic rod.

[0067] By using the horizontal screw 10 and the horizontal screw 2 12 to cooperate with the connecting block 111 and the connecting block 2 131 respectively, the scraper 11 and the scraper 2 13 in the same group are stacked together, and the scraper 11 in the two groups of scrapers is located in the same vertical plane. Then, the connecting telescopic rod 15 is activated, so that the connecting telescopic rod 15 is inserted into the corresponding connecting hole. At this time, the scraper 11 in the two groups of scrapers is connected together, and the garbage inside the garbage can can be leveled in the length direction of the garbage can 1.

[0068] Alternatively, a connecting telescopic rod 15 can be provided on the end face of one of the two sets of scrapers 13 near the scraper 11, and a connecting hole can be provided on the end face of the other set of scrapers 11 near the scraper 13. The connecting telescopic rod 15 in the two sets of scrapers 13 can cooperate with the connecting hole to improve the strength of the combined connection of the two sets of scrapers.

[0069] The garbage bin 1 has two sets of vertical screws 8 installed inside. The bottom of the garbage bin 1 is equipped with a motor module that drives the vertical screws 8 to rotate. The two sets of vertical screws 8 are distributed on both sides of the width direction inside the garbage bin 1. Each set of vertical screws 8 has two vertical screws 8. The two vertical screws 8 in the same set are distributed at both ends of the horizontal screw in the same set.

[0070] The surface of the vertical screw 8 is threadedly connected to a mounting base 81. An adjusting telescopic rod 9 is fixedly installed inside the mounting base 81. The adjusting telescopic rod 9 is a hydraulic rod and is distributed along the width of the garbage bin 1. The telescopic end of the adjusting telescopic rod 9 is fixedly installed with a mounting base 91. The ends of the transverse screws 10 and 12 in the same group are rotatably connected to the mounting base 91. A motor module for driving the transverse screws 10 and 12 to rotate is installed on the surface of the mounting base 91.

[0071] By using the vertical screw 8 and the mounting base 81, the position of the scraper can be adjusted up and down. The position of the scraper can be adjusted in the width direction of the garbage bin 1 by using the adjusting telescopic rod 9. When scraper 11 and scraper 2 13 in the same group of scrapers are combined to form a V-shaped structure, the adjusting telescopic rod 9 cooperates with scraper 11 and scraper 2 13 in the V-shaped structure to level the garbage inside the garbage bin 1 in the width direction of the garbage bin 1. This design can reduce the design stroke of the adjusting telescopic rod 9.

[0072] An automated method for loading and unloading food waste from a kitchen waste truck includes the following specific steps:

[0073] S1. First, turn the opening of the trash can downwards and align it with the disposal port 101. Under the influence of gravity, some of the trash inside the trash can falls downwards into the trash can 1.

[0074] S2. Activate hydraulic rod 3 and lifting rod 4 to push the mounting frame 5 upward, and activate hydraulic rod 411 to tilt the mounting frame 5 so that the spiked roller 6 in the mounting frame 5 can enter the garbage can from a position close to the inner wall of the garbage can.

[0075] S3. Start the motor on the side surface of the mounting frame 5. The motor, in conjunction with the toothed belt 7 and the transmission gear 71, drives several spiked rollers 6 to rotate. The spikes 61 on the surface of the spiked rollers 6 exert a pushing force on the garbage. Through the cooperation of several spiked rollers 6, the garbage is pushed downwards.

[0076] S4. When the garbage inside the garbage bin is severely clogged, adjust the tilt angle of the mounting bracket 5. When one or more of the spiked rollers 6 are greatly obstructed from rotating, a speed difference will occur between the obstructed spiked roller 6 and the adjacent spiked roller 6. The speeds of the two or more spiked rollers 6 will be out of sync. With the cooperation of the spikes 61, the garbage that is squeezed together will be dispersed, and the garbage inside the garbage bin will be further discharged.

[0077] S5. After the garbage is put into the garbage bin 1, the vertical screw 8, the horizontal screw 10, the horizontal screw 2 12 and the adjusting telescopic rod 9 are used to flatten the garbage put into the garbage bin 1 in the width direction.

[0078] S6. Use the horizontal screw 10 and the horizontal screw 2 to adjust the position of scraper 11 and scraper 2 13 so that the two scrapers 11 in the two sets of scrapers are adjusted to the same vertical plane. Then start the connecting telescopic rod 15 so that the connecting telescopic rod 15 is inserted into the corresponding connecting hole so that the two sets of scrapers are connected together.

[0079] S7. Using the transverse screw 10 and transverse screw 2 12, drive the two sets of scrapers to move synchronously along the length of the garbage bin 1, and flatten the garbage put into the garbage bin 1 in the width direction.

[0080] The working principle of a food waste truck:

[0081] First, the trash can is lifted to the position of the disposal opening 101 using the lifting bracket 2. Then, the opening of the trash can is flipped downwards to align with the disposal opening 101, and the trash inside the trash can falls downwards into the trash bin 1. When the trash inside the trash can is relatively compacted, the mounting frame 5 is pushed upwards using the hydraulic rod 3 and the lifting rod 4. The mounting frame 5 is tilted and adjusted using the hydraulic rod 411, so that the spiked roller 6 in the mounting frame 5 can enter the trash can from a position close to the inner wall of the trash can.

[0082] The motor on the side surface of the mounting frame 5 is activated. The motor, in conjunction with the toothed belt 7 and the transmission gear 71, drives several spiked rollers 6 to rotate. When the spiked rollers 6 rotate and come into contact with the garbage inside the garbage bin, the spikes 61 on the surface of the spiked rollers 6 exert a pushing force on the garbage. The several spiked rollers 6 work together to help push the garbage downwards. When the garbage inside the garbage bin is severely blocked, the tilt angle of the mounting frame 5 is adjusted appropriately. At the same time, when one or more spiked rollers 6 are subject to greater resistance, a speed difference occurs between the blocked spiked roller 6 and the adjacent spiked roller 6. The speeds of two or more spiked rollers 6 are not synchronized. Under the action of the spikes 61, the garbage that is squeezed together is dispersed, thereby preventing garbage blockage and facilitating the discharge of garbage from inside the garbage bin.

[0083] After the garbage is put into garbage bin 1, the vertical screw 8 is driven to rotate by the motor module, which can adjust the position of the scraper in the vertical direction. The horizontal screw 10 and / or horizontal screw 12 are driven to rotate by the motor module, which can adjust the horizontal position of scraper 11 and scraper 13. The adjusting telescopic rod 9 is activated, which can adjust the position of the scraper in the width direction of garbage bin 1. Therefore, by using the vertical screw 8, horizontal screw 10, horizontal screw 12 and adjusting telescopic rod 9, the garbage put into garbage bin 1 can be leveled in the width direction of garbage bin 1.

[0084] By adjusting the positions of scraper 11 and scraper 213 using horizontal screw 10 and horizontal screw 212, scraper 11 and scraper 213 in the same group of scrapers are folded together, and the two scraper 11s in the two groups of scrapers are adjusted to the same vertical plane. Then, the connecting telescopic rod 15 is activated and inserted into the corresponding connecting hole, so that the two groups of scrapers are connected together. At this time, the horizontal screw 10 and horizontal screw 212 drive the two groups of scrapers to move synchronously along the length of the garbage bin 1, so that the garbage put into the garbage bin 1 can be leveled in the width of the garbage bin 1.

[0085] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
