Description

Technical Field

[0001] This utility model relates to the field of garbage truck technology, specifically to a hopper mechanism for garbage trucks. Background Technology

[0002] In urban environmental sanitation management, garbage trucks, as the core equipment for garbage collection and transportation, directly impact the quality and progress of urban sanitation work due to their operational efficiency. The hopper mechanism, a key component of the garbage truck, plays a crucial role in garbage collection, temporary storage, and transportation. Currently, common garbage truck hopper mechanisms on the market suffer from problems such as limited functionality and restricted operation: traditional hoppers mostly only scoop up loose garbage accumulated on the ground by moving the garbage truck itself. For accumulated garbage in the bins, it is often necessary to manually move the bins to the hopper for dumping, which not only increases the labor intensity of workers but also poses the risk of garbage scattering during dumping, affecting the working environment. Meanwhile, the traditional hopper mechanism has a fixed position and cannot be flexibly adjusted relative to the ground according to the needs of operation. When faced with garbage in different pile states, the shoveling effect is not good and it is difficult to adapt to various operation scenarios, which limits the scope of use of the hopper, reduces the utilization rate of the device, and greatly reduces its practicality.

[0003] Therefore, a hopper mechanism for garbage trucks is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a hopper mechanism for garbage trucks to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A hopper mechanism for a garbage truck includes a fixed frame. A hopper assembly for multi-functional garbage collection is rotatably connected inside the fixed frame. A positioning component for positioning a garbage bin within the hopper assembly is installed inside the hopper assembly. A groove is formed inside the hopper assembly, and a protective component for restricting the position of garbage or a garbage bin within the hopper assembly is rotatably connected inside the groove. The hopper assembly includes a first motor and a rotating rod. The first motor is mounted on the left side of the fixed frame. Through holes are formed on the inner walls of both the left and right sides of the fixed frame. The rotating rod is rotatably connected to the two sets of through holes in the fixed frame. The output shaft of the first motor passes through the left through hole of the fixed frame and is mounted on one end of the rotating rod. A fixed sleeve is mounted on the outer end of the rotating rod. Two sets of rotating arms are mounted on the outer surface of the fixed sleeve. Each set of rotating arms has a groove inside. An electromagnetic rod is installed inside the groove of the two sets of rotating arms. A connecting sleeve is rotatably connected to the outer surface of the electromagnetic rod, and a hopper is mounted on the outer surface of the connecting sleeve.

[0006] Furthermore, the positioning component includes two sets of electric telescopic rods, and through holes are provided on the outer surfaces of both the left and right sides of the hopper. The two sets of electric telescopic rods are respectively installed inside the two sets of through holes of the hopper, and positioning plates are installed at the output ends of the two sets of electric telescopic rods.

[0007] Furthermore, the protective assembly includes a second motor and a first cleaning plate. A groove is provided on the left inner wall of the hopper. One side of the first cleaning plate is rotatably connected to the groove of the hopper. The second motor is installed on the left side of the hopper. The output shaft of the second motor passes through the groove inside the hopper and is installed on one side of the first cleaning plate. A slot is provided on the side of the first cleaning plate away from the second motor. The second cleaning plate is slidably connected inside the slot of the first cleaning plate. The lower ends of the first cleaning plate and the second cleaning plate abut against the bottom of the inner wall of the hopper.

[0008] Furthermore, each of the two sets of positioning plates has a groove on one side adjacent to the other. A pressure sensor is installed inside the groove of the positioning plate, and the pressure sensor is electrically connected to the control end of the electric telescopic rod.

[0009] Furthermore, a through hole is provided on one side of both the first cleaning plate and the second cleaning plate, and a rod is inserted into the through hole of the first cleaning plate and the second cleaning plate.

[0010] The beneficial effects of this utility model are as follows: 1. This utility model uses a first motor and an electromagnetic rod to rotate the connecting sleeve on one side of a fixed frame, bringing the lower surface of the hopper to the ground. Then, a garbage truck is started to move the hopper across the ground, scooping up accumulated garbage. Simultaneously, workers push a garbage bin into the hopper, allowing the hopper to empty the accumulated garbage from the bin while scooping it up. This expands the hopper's usability and increases the device's utilization rate, thus enhancing its practicality.

[0011] 2. This utility model uses a second motor to drive the first and second cleaning plates to rotate. During rotation, the first and second cleaning plates push the garbage accumulated at the edge of the hopper to its central area, and the lower surfaces of the first and second cleaning plates abut against the bottom of the inner wall of the hopper. This restricts the movement path of the garbage accumulated inside the hopper, preventing the garbage accumulated at the edge from falling out when the hopper is tilted and dumped. By pushing the second cleaning plate out of the slot of the first cleaning plate, the second cleaning plate can be disassembled, preventing the protective component from blocking the staff from pushing the garbage can into the hopper.

[0018] like Figures 1 to 4 As shown, a hopper mechanism for a garbage truck includes a fixed frame 1, and a hopper assembly 2 for multi-functional garbage collection is rotatably connected inside the fixed frame 1, such as... Figures 1-2 As shown, the hopper assembly 2 includes a first motor 201 and a rotating rod 202. The first motor 201 is installed on the left side of the fixed frame 1. The inner walls of both the left and right sides of the fixed frame 1 are provided with through holes. The rotating rod 202 is rotatably connected to the two sets of through holes in the fixed frame 1. The output shaft of the first motor 201 passes through the left through hole of the fixed frame 1 and is installed at one end of the rotating rod 202. A fixed sleeve 203 is installed on the outer end of the rotating rod 202. Two sets of rotating arms 204 are installed on the outer surface of the fixed sleeve 203. The interior of each set of rotating arms 204 is provided with a groove. An electromagnetic rod 205 is installed inside the groove of each set of rotating arms 204. A connecting sleeve 206 is rotatably connected to the outer surface of the electromagnetic rod 205. A hopper 207 is installed on the outer surface of the connecting sleeve 206.

[0019] More specifically, by starting the first motor 201 and the electromagnetic rod 205, the connecting sleeve 206 is rotated on one side of the fixed frame 1, causing the lower surface of the hopper 207 to come into contact with the ground. Then, by starting the garbage truck, the hopper 207 is moved on the ground, so that the hopper 207 scoops up the garbage accumulated on the ground during the movement. At this time, the staff pushes the garbage can into the hopper 207, so that the hopper 207 can simultaneously empty the garbage accumulated in the garbage can while scooping up the garbage, thereby expanding the scope of use of the hopper 207 and improving the utilization rate of the device, thus improving the practicality of the device.

[0020] The hopper assembly 2 is internally equipped with a positioning component 3 for positioning the trash can within its own interior, such as... Figure 1 As shown, the positioning component 3 includes two sets of electric telescopic rods 301. Through holes are provided on the outer surfaces of both sides of the hopper 207. The two sets of electric telescopic rods 301 are respectively installed inside the two sets of through holes of the hopper 207. Positioning plates 302 are installed at the output ends of the two sets of electric telescopic rods 301.

[0021] More specifically, after the garbage truck is pushed into the hopper 207, the position of the garbage truck is adjusted and moved between the two sets of positioning plates 302 by pushing the garbage truck. Then, the two sets of electric telescopic rods 301 are activated to push the two sets of positioning plates 302 to move, so that the adjacent sides of the two sets of positioning plates 302 respectively abut against the left and right sides of the garbage truck. This allows the positioning component 3 to restrict the movement of the garbage truck inside the hopper 207, preventing the garbage truck from moving during the tipping of the hopper 207, thus improving the safety of the device during use.

[0022] The hopper assembly 2 has a groove inside, and a protective component 5 is rotatably connected inside the groove to limit the position of garbage or garbage can inside the hopper assembly 2. Figure 2 As shown, the protective component 5 includes a second motor 501 and a first cleaning plate 502. A groove is provided on the left inner wall of the hopper 207. One side of the first cleaning plate 502 is rotatably connected to the inside of the groove of the hopper 207. The second motor 501 is installed on the left side of the hopper 207. The output shaft of the second motor 501 passes through the groove inside the hopper 207 and is installed on one side of the first cleaning plate 502. A slot is provided on the side of the first cleaning plate 502 away from the second motor 501. A second cleaning plate 503 is slidably connected inside the slot of the first cleaning plate 502. The lower ends of the first cleaning plate 502 and the second cleaning plate 503 abut against the bottom of the inner wall of the hopper 207.

[0023] More specifically, when the hopper 207 is scooping up accumulated garbage, the second motor 501 is activated to drive the first cleaning plate 502 and the second cleaning plate 503 to rotate. During the rotation, the first cleaning plate 502 and the second cleaning plate 503 push the garbage accumulated at the edge of the hopper 207 to its central area, and the lower surfaces of the first cleaning plate 502 and the second cleaning plate 503 abut against the bottom of the inner wall of the hopper 207. This restricts the movement path of the garbage accumulated inside the hopper 207, preventing the garbage accumulated at the edge from falling when the hopper 207 is tipped over and dumped. By pushing the second cleaning plate 503, the second cleaning plate 503 is moved out of the slot of the first cleaning plate 502, allowing the second cleaning plate 503 to be disassembled, preventing the protective component 5 from blocking the staff from pushing the garbage can into the hopper 207.

[0024] Both sets of positioning plates 302 have grooves on adjacent sides. Pressure sensors 4 are installed inside the grooves of the positioning plates 302. The pressure sensors 4 are electrically connected to the control end of the electric telescopic rod 301.

[0025] More specifically, pressure sensors 4 are installed on the adjacent side of the two sets of positioning plates 302. When the two sets of positioning plates 302 are attached to the left and right sides of the trash can, the two sets of pressure sensors 4 squeeze the left and right sides of the trash can. When the squeezing value of the pressure sensor 4 exceeds the preset value, the electric telescopic rod 301 is turned off to push the positioning plate 302 to move, so as to avoid the positioning component 3 from excessively clamping the trash can during use, which would cause damage to the trash can during the positioning process.

[0026] Both the first cleaning plate 502 and the second cleaning plate 503 have through holes on one side, and insert rods 6 are inserted into the through holes of the first cleaning plate 502 and the second cleaning plate 503.

[0027] More specifically, before the second cleaning plate 503 is spliced ​​to one side of the first cleaning plate 502 for use, the insert rod 6 is pushed to insert it into the through hole of the first cleaning plate 502 and the second cleaning plate 503. This restricts the rotation position of the second cleaning plate 503 on one side of the first cleaning plate 502, preventing the second cleaning plate 503 from moving during use, thus improving the stability of the protective component 5 during use.

[0028] In summary: By starting the first motor 201 and the solenoid rod 205, the connecting sleeve 206 rotates on one side of the fixed frame 1, causing the lower surface of the hopper 207 to contact the ground. Then, by starting the garbage truck, the hopper 207 is moved on the ground, scooping up the garbage accumulated on the ground. At this time, the workers push the garbage bin into the hopper 207, so that the hopper 207 can simultaneously empty the garbage accumulated in the garbage bin while scooping up the garbage. By starting the second motor 201 and the solenoid rod 205, the connecting sleeve 206 rotates on one side of the fixed frame 1, causing the lower surface of the hopper 207 to contact the ground. Then, by starting the garbage truck, the hopper 207 can move the garbage truck on the ground, causing the hopper 207 to ... The two motors 501 drive the first cleaning plate 502 and the second cleaning plate 503 to rotate, so that the first cleaning plate 502 and the second cleaning plate 503 push the garbage accumulated at the edge of the hopper 207 to its central area during the rotation, and the lower surfaces of the first cleaning plate 502 and the second cleaning plate 503 abut against the bottom of the inner wall of the hopper 207, so that the protective component 5 restricts the movement path of the garbage accumulated inside the hopper 207, and prevents the garbage accumulated at the edge of the hopper 207 from falling off when the hopper 207 is tilted and dumped.
