Description

Technical Field

[0001] The present invention relates to the technical field of garbage trucks, and specifically to a garbage truck with the function of cleaning trash cans. Background Art

[0002] Garbage trucks are crucial for urban cleaning and play an important role. In daily life, they regularly shuttle through the streets and alleys, efficiently collecting various types of garbage generated by residents and merchants, preventing garbage accumulation from breeding bacteria and spreading diseases, and maintaining the cleanliness and hygiene of the urban environment.

[0003] For example, the Chinese patent with the authorization announcement number CN102658941B discloses a garbage truck, which includes a vehicle frame, a garbage bin located above the vehicle frame, and a lifting mechanism. The garbage bin is moved between an initial position and a working position through the lifting mechanism. In the initial position, the bottom of the garbage bin slopes forward and downward.

[0004] However, there are still some problems in the above-mentioned prior art. Although the above-mentioned prior art can achieve the collection and transportation of garbage, after the trash can has been used for a long time, there will be oil stains or viscous substances attached to the trash can. The viscous substances can be separated from the trash can by increasing the air pressure, but for the oil stains, it is necessary to manually spray a cleaning agent to make the cleaning agent react with the oil stains, so as to complete the cleaning work of the oil stains. Since the trash can is used for placing garbage, the probability of its being contaminated will increase, and manual cleaning will increase the workload of the operators.

[0005] Therefore, how to complete the cleaning work of the trash can is a problem to be solved at present. Summary of the Invention

[0059] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given with reference to the accompanying drawings of the specification.

[0060] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar promotions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0061] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present invention. The "in one embodiment" appearing in different places in this specification does not all refer to the same embodiment, nor is it an embodiment that is separate or selectively mutually exclusive with other embodiments.

[0062] The present invention discloses a garbage truck with the function of cleaning garbage bins. Refer to Figures 1-9 , including:

[0063] Garbage truck 1, used for the collection and transportation of garbage; medicine injection unit 3, arranged on the garbage truck 1, connecting pipe 5 connected to the medicine injection unit 3, the medicine injection unit 3 is used for the transportation of medicine and the mixing of medicine and clean water to complete the preparation of cleaning liquid; spraying unit 4, connected to the connecting pipe 5, used for spraying medicine on the garbage can; the medicine injection unit 3 includes box body 31, protective cover 35, heating component 32, water inlet pipe 33 and medicine injection component 34; box body 31, arranged on the garbage truck 1 and connected to the protective cover 35; heating component 32, arranged in the box body 31, and setting the heating temperature according to the type of injected medicine; water inlet pipe 33, passing through the box body 31, and the heating component 32 is sleeved on the water inlet pipe 33; medicine injection component 34, connected to the box body 31, used for injecting medicine into the box body 31; this device also includes a water pump, through the movement of the water pump, clean water can be transported into the water inlet pipe 33 to ensure the smooth progress of the cleaning work and the preparation work of the cleaning agent. Through the arranged medicine injection unit 3, cleaning agent can be sprayed into the garbage can, so that the cleaning agent can be sprayed to the predetermined position, and then through the arranged spraying unit 4, the flushing work of the cleaning agent can be completed. There is no need for manual spraying of the cleaning agent, which reduces the work burden of the operator. Moreover, there is a medicine bin in this device, and the medicine bin contains medicine. When it is necessary to clean the garbage can, only by controlling the opening and closing of the electromagnetic valve 348, the medicine can be mixed with the clean water in the water inlet pipe 33 to form cleaning liquid, so that the cleaning liquid can spray the garbage can, and the cleaning agent can react with the stains in the garbage can, facilitating the subsequent cleaning work of the operator.

[0064] In a further embodiment, the active ingredients of many cleaning agents have better solubility in warm water. Taking common oil stain cleaning agents as an example, as the temperature rises, components such as surfactants can be more fully dissolved and dispersed in water, forming a more uniform cleaning liquid, thereby better exerting its functions of emulsifying and dispersing oil stains and improving the cleaning ability of oil stains; while in winter or extreme weather, the water temperature will be relatively low, which will lead to a decrease in the solubility of the medicine or the effectiveness of components such as surfactants, resulting in a poor cleaning effect; at the same time, most of the existing medicine ratios are pre-prepared, and then clean water is sprayed on the garbage can through the nozzle body for preliminary cleaning work. During this process, the temperature of the medicine will decrease, resulting in a weakening of the effectiveness of the medicine.

[0065] To solve the above problems, a heating component 32 is provided in the present device. The heating component 32 includes a preheating chamber 321 sleeved on the water inlet pipe 33. The preheating chamber 321 is of a ring structure. A preheating cavity is formed between the inner wall and the outer wall of the preheating chamber 321, and a bath solution is filled in the preheating cavity. The heating component 32 further includes a wire inlet nozzle 322 and a limit seat 325 provided on the box body 31, a water inlet pipe 323 connected to the wire inlet nozzle 322. One end of the water inlet pipe 323 away from the wire inlet nozzle 322 is of a ring structure, and a plurality of heating rods 324 are provided on the water inlet pipe 323. The heating rods 324 are located in the preheating cavity. A power transmission line is provided in the wire inlet nozzle 322. The power transmission line is located in the water inlet pipe 323 and is connected to one end of the heating rod 324. The other end of the power transmission line is connected to a power supply. The limit seat 325 abuts against the preheating chamber 321, and the water inlet pipe 323 is sleeved on the limit seat 325. When the preparation work of the medicament is completed, the medicament can be injected through the injection nozzle 347 at this time. Then, the medicament can fall into the medicament bin through the gap between the drainage part 346 and the preheating chamber 321 along the injection pipe 341. Then, the power supply is turned on to make the power transmission line charged. The charged power transmission line is connected to the heating rod 324 to make the heating rod 324 in a working state, so as to increase the temperature of the bath solution. This process occurs during the process of the nozzle body spraying clean water, and no additional preheating time is required. By increasing the temperature of the medicament, the cleaning effect of the medicament is improved, and at the same time, the precipitation of solute can be avoided, and the concentration of the medicament can be prevented from decreasing, so that the cleaning effect becomes low. In a further embodiment, in order to avoid the temperature of the medicament being too high, a bath solution with a corresponding boiling point can be selected for filling, or a temperature sensor is provided in the preheating cavity to measure the bath solution, so as to avoid the temperature of the bath solution being too high and keep the temperature of the medicament within a certain range to ensure the cleaning effect of the medicament.

[0066] The medicine injection assembly 34 includes a medicine injection nozzle 347 provided on the box body 31, a medicine injection tube 341 connected to the medicine injection nozzle 347, a drainage part 346 connected to the medicine injection tube 341 and arranged inside the box body 31, and an installation part sleeved on the water inlet pipe 33; the drainage part 346 is connected to the installation part; the installation part penetrates through the preheating chamber 321, one end of which is connected to the bottom of the preheating chamber 321, and the other end is higher than the top of the preheating chamber 321, so that there is a gap between the drainage part 346 and the preheating chamber 321, and the gap is used for the circulation of the medicine; a U-shaped medicine bin is formed between the inner wall of the preheating chamber 321 and the installation part; the installation part includes a support seat 342 sleeved on the water inlet pipe 33, a bearing 343 sleeved on the water inlet pipe 33 and abutted against the support seat 342, and a sealing ring located between the bearing 343 and the support seat 342; a circular protrusion is further provided inside the support seat 342, a limiting spring 345 abutted against the circular protrusion, and a butting pipe 344 connected to the other end of the limiting spring 345, and the butting pipe 344 abuts against the bearing 343 away from the water inlet end of the water inlet pipe 33; the support seat 342 is of an I-shaped structure, and its bottom is used to block the bottom of the preheating chamber 321; a plurality of electromagnetic valves 348 are provided on the support seat 342; when the medicine falls into the medicine bin from the gap between the drainage part 346 and the preheating chamber 321, at this time, the bath solution can heat the medicine in the medicine bin, increase the temperature of the medicine, so that the temperature of the medicine can be within a certain range. When the operator completes the preliminary cleaning work of the trash can or needs to carry out the medicine spraying work, at this time, the electromagnetic valve 348 starts to work, so that the medicine can be sprayed out from the electromagnetic valve 348. And because the water flow in the water inlet pipe 33 has a certain speed, according to the Venturi effect, the medicine can be mixed with the clear water or the clear water is not transported, so that the cleaning agent or the medicine can be sprayed on the trash can to complete the medicine spraying work.

[0067] In a further embodiment, since the medicine in the device is transported from the drainage part 346, and during the transportation process, a certain impact force will be generated on the drainage part 346, which will cause the displacement of the drainage part 346, thus causing the instability of the whole device;

[0068] And in this device, by setting the limiting spring 345 in a compressed state, the elastic force generated by the limiting spring 345 can apply pressure to the butting pipe 344 and the support seat 342, increasing the axial pressure of the butting pipe 344 and the support seat 342 on the bearing 343. And the first sealing disk 3462 is connected to the box body 31, which can also play a role in limiting the device, thus ensuring the stability of the device.

[0069] The water inlet pipe 33 is of an integral structure. The water inlet pipe 33 is an axisymmetric figure, and both ends of the water inlet pipe 33 are symmetric about the connection line of the midpoint of the length of the water inlet pipe 33. One end of the water inlet pipe 33 includes three transport pipes with different diameters. Among the three transport pipes, the one with the largest diameter is the first transport pipe, the one with the smallest diameter is the third transport pipe, and the remaining one is the second transport pipe, as well as a transition pipe for connecting the first transport pipe and the second transport pipe. The second transport pipe is connected to the third transport pipe. The bearing 343 is sleeved on the second transport pipe and abuts against the transition pipe. By setting the transport pipes with different diameters, the water inlet pipe 33 can abut against the bearing 343. At the same time, by setting the sealing ring, the stability of the water inlet pipe 33 can be ensured, preventing the water inlet pipe 33 from shaking under the impact of high-speed water flow, avoiding collision between the water inlet pipe 33 and the medicine storage tank, ensuring the stability of the device, and preventing damage to the water inlet pipe 33.

[0070] In a further embodiment, most of the existing medicine supplement methods directly transport the medicine to the medicine storage tank through a pipeline. This method will cause the medicine to only impact the same position. After long-term impact, the inner wall of the preheating chamber 321 will be damaged, which is likely to cause leakage of the bath solution. At the same time, if the medicine is transported in the above manner, since the medicine in the pipeline has a certain initial velocity, during the movement process, the medicine will collide with the preheating chamber 321, and thus it is easy for the medicine to scatter, resulting in a slower filling speed of the medicine storage tank. If the injection nozzle body is used for movement, although the transportation of the medicine can be made more uniform, the diameter of the water spray opening of the injection nozzle body is small, which is likely to cause blockage of the injection nozzle body, resulting in the failure of the medicine transportation work.

[0071] To solve the above problems, a drainage part 346 is provided in the present device. The drainage part 346 includes a first sealing disk 3462 disposed in the box body 31 and sleeved on the water inlet pipe 33, a second sealing disk 3463 sleeved on the water inlet pipe 33 and connected to the first sealing disk 3462, and a connection disk 3467 connected to the first sealing disk 3462. A plurality of water outlet holes are provided on the connection disk 3467 for injecting the medicament into the gap between the drainage part 346 and the preheating chamber 321. An insertion hole for the medicine injection pipe 341 to be inserted is formed on the first sealing disk 3462. A first channel 3464 and a second channel 3465 are provided on the second sealing disk 3463, and a third channel 3466 is further provided on the first sealing disk 3462. The connection disk 3467 is the bottom of the third channel 3466. A plurality of the second channels 3465 are provided and evenly distributed on the second sealing disk 3463. A plurality of communication holes 3468 for connecting the second channel 3465 and the third channel 3466 are provided on the first sealing disk 3462. When the medicament transportation work is carried out, the medicament is transported from the medicine injection nozzle 347 into the medicine injection pipe 341, and then the medicament flows along the first channel 3464, the second channel 3465 and the communication holes 3468, so that the medicament is located in the third channel 3466, and then the medicament falls into the gap from the water outlet holes on the connection disk 3467. Compared with the traditional direct injection method, the above device can adjust the injection speed and injection range of the medicament, avoid the damage of the medicament bin caused by the long-term high-speed impact of the medicament, and at the same time, compared with the nozzle body, it has a larger diameter and is not easy to be blocked, ensuring the smooth progress of the medicament injection work.

[0072] The injection unit 4 includes a nozzle body, a connecting plate 41 fixedly installed on the nozzle body, a micro cylinder 42 disposed on the connecting plate 41, a first connecting rod 43 movably connected to the output end of the micro cylinder 42, a transmission shaft 44 connected to the first connecting rod 43, a second connecting rod 45 movably connected to the transmission shaft 44, a connecting block 46 connected to the second connecting rod 45, and a sealing portion 47 connected to the connecting block 46; the sealing portion 47 includes a water outlet pipe 479 sleeved on the nozzle body, a guide plate 48 connected to the water outlet pipe 479; a driving rod 475 movably connected to the connecting block 46, a sealing plate 471 connected to the driving rod 475, a hinge 472 connected to the sealing plate 471, a guide hole is formed on the sealing plate 471, an adjusting bolt 478 movably connected to the inner wall of the guide hole, a return spring 477 connected to the adjusting bolt 478, and a limiting ball 476 connected to the return spring 477; one end of the hinge 472 is connected to the sealing plate 471 and the other end is disposed on the water outlet pipe 479; the guide plate 48 is an arc-shaped structure and is provided with at least two limiting holes; a limiting rod 474 is further provided on the sealing plate 471, a base 473 disposed on the water outlet pipe 479, and an elastic sheet built in the base 473. Through the deformation of the elastic sheet, the position of the limiting rod 474 can be fixed, and then in cooperation with the operation of the micro cylinder 42, the sealing plate 471 can perform the sealing work. A sealing gasket can also be provided on the sealing plate 471 to improve the sealing performance and prevent sand or dust from clogging the nozzle body; when the injection work of the cleaning agent needs to be carried out, the micro cylinder 42 starts to work. The moving micro cylinder 42 can drive the first connecting rod 43 to move. The moving first connecting rod 43 can drive the transmission shaft 44 to move, causing the second connecting rod 45 to rotate. The moving second connecting rod 45 can drive the driving rod 475 to move through the provided connecting block 46, so that the driving rod 475 can drive the sealing plate 471 to move, making the sealing plate 471 away from the nozzle of the water outlet pipe 479 to realize the injection work of the cleaning agent. By providing the adjusting bolt 478, the deformation amount of the return spring 477 can be adjusted, so that the pressure of the limiting ball 476 on the guide plate 48 can be adjusted to ensure the sealing work.

Then the limiting wrench 296 is rotated so that the positioning rod 297 abuts against the limiting protrusion 295, thus completing the locking work of the trash can. Then the lifting cylinder 23 starts to work. The moving lifting cylinder 23 can drive the lifting gear 24 to move. Through the arranged lifting chain 25, the lifting seat 26 can be driven to move. Since the movable seat 27 is hinged to the lifting seat 26, when the universal wheel 28 on the movable seat 27 is located in the arc area at the top of the guide rail 21, the angle between the movable seat 27 and the lifting seat 26 changes, thus completing the turning-over work of the trash can, so that the garbage in the trash can can fall into the garbage truck 1 to complete the garbage dumping work.

[0076] After the preparation of the medicament is completed, the medicament can be injected through the injection nozzle 347 at this time. Then, the medicament can fall into the medicament bin through the gap between the drainage part 346 and the preheating chamber 321 along the injection pipe 341. Then, the power supply is turned on to make the transmission line charged. The charged transmission line is connected to the heating rod 324 to make the heating rod 324 in a working state, increasing the temperature of the bath solution. This process occurs during the spraying of clean water by the nozzle body and does not require additional preheating time. By increasing the temperature of the medicament, the cleaning effect of the medicament is improved. At the same time, the precipitation of the solute can be avoided, and the concentration of the medicament can be prevented from decreasing, so that the cleaning effect does not become low. After the medicament falls into the medicament bin through the gap between the drainage part 346 and the preheating chamber 321, at this time, the bath solution can heat the medicament in the medicament bin to increase the temperature of the medicament so that the temperature of the medicament can be within a certain range. When the operator completes the preliminary cleaning work of the trash can or needs to carry out the spraying work of the medicament, the solenoid valve 348 starts to work at this time, so that the medicament can be sprayed out from the solenoid valve 348. Since the water flow in the water inlet pipe 33 has a certain speed, according to the Venturi effect, the medicament can be mixed with the clean water or the transportation of clean water can be omitted, so that the cleaning agent or the medicament can be sprayed on the trash can to complete the spraying work of the medicament. When carrying out the medicament transportation work, the medicament is transported from the injection nozzle 347 into the injection pipe 341. Then, the medicament follows the first channel 3464, the second channel 3465 and the communication hole 3468, and then the medicament is located in the third channel 3466. Then, the medicament falls into the gap from the water outlet holes on the connecting disk 3467, and then the medicament can fall into the medicament bin. When the spraying work of the cleaning agent needs to be carried out, the micro cylinder 42 starts to work. The moving micro cylinder 42 can drive the first connecting rod 43 to move. The moving first connecting rod 43 can drive the transmission shaft 44 to move, making the second connecting rod 45 rotate. The moving second connecting rod 45 can drive the driving rod 475 to move through the set connecting block 46, so that the driving rod 475 can drive the sealing plate 471 to move, making the sealing plate 471 away from the pipe orifice of the water outlet pipe 479 to realize the spraying work of the cleaning agent.
