Description

Technical Field

[0001] The invention relates to the technical field of garbage trucks, in particular to a garbage truck with a garbage bin cleaning function. Background Art

[0002] Garbage trucks are the key to urban cleanliness and play an important role. In daily life, they regularly shuttle through the streets and alleys, efficiently collecting all kinds of garbage generated by residents and businesses, preventing garbage from accumulating and breeding bacteria and spreading diseases, and maintaining a clean and hygienic urban environment.

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

[0004] However, there are still some problems with the above-mentioned prior art. Although the above-mentioned prior art can realize the collection and transportation of garbage, after the garbage can is used for too long, oil stains or sticky substances will be attached to the garbage can. The sticky substances can be separated from the garbage can by increasing the air pressure, but the oil stains require manual spraying of detergents to make the detergents react with the oil stains, thereby completing the cleaning of the oil stains. Since the garbage can is used to place garbage, the probability of it being contaminated will increase, and manual cleaning will increase the workload of the operator.

[0059] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0060] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0061] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0062] The present invention discloses a garbage truck with a garbage can cleaning function, referring to Figure 1-Figure 9 ,include:

[0063] The garbage truck 1 is used for collecting and transporting garbage; the medicine injection unit 3 is arranged on the garbage truck 1, and the connecting pipe 5 connected to the medicine injection unit 3 is used for transporting the medicine and mixing the medicine with clean water to complete the configuration of the cleaning liquid; the spraying unit 4 is connected to the connecting pipe 5 and is used to spray the medicine on the garbage can; the medicine injection unit 3 includes a box body 31, a protective cover 35, a heating component 32, a water inlet pipe 33 and a medicine injection component 34; the box body 31 is arranged on the garbage truck 1 and is connected to the protective cover 35; the heating component 32 is arranged in the box body 31, and the heating temperature is set according to the type of injected medicine; the water inlet pipe 33 runs through the box body 31, and the heating component 32 is sleeved on the water inlet pipe 33; the medicine injection component 34 is connected to the box body 31 and is used to inject the medicine into the box body 31 The device also includes a water pump, through the movement of which clean water can be transported to the water inlet pipe 33, ensuring the smooth progress of the cleaning work and the cleaning agent configuration work. Through the provided injection unit 3, the cleaning agent can be sprayed into the trash can, so that the cleaning agent can be sprayed to a predetermined position, and then the cleaning agent is flushed through the provided spray unit 4. There is no need to manually spray the cleaning agent, which reduces the workload of the operator. In addition, a medicine bin is provided in the device, which contains medicine. When the trash can needs to be cleaned, it is only necessary to control the opening and closing of the solenoid valve 348 to mix the medicine with the clean water in the water inlet pipe 33, thereby forming a cleaning liquid, so that the cleaning liquid can be sprayed on the trash can, and the cleaning agent can react with the stains in the trash can, which is convenient for subsequent cleaning work by the operator.

[0064] In further embodiments, the effective ingredients of many cleaning agents are more soluble in warm water. Taking common oil cleaning agents as an example, the increase in temperature can make surfactants and other ingredients more fully dissolved and dispersed in water, forming a more uniform cleaning solution, thereby better exerting its role in emulsifying and dispersing oil stains and improving its ability to clean oil stains; in winter or extreme weather, the water temperature will be low, resulting in lower solubility of the agent or the effect of surfactants and other ingredients, resulting in poor cleaning effect; at the same time, most of the existing agent ratios are pre-proportioned, and then the nozzle body is used to spray clean water onto the trash can for preliminary cleaning, and in this process, the agent temperature will be reduced, causing the agent's effectiveness to weaken.

[0065] In order to solve the above problems, the device is provided with a heating component 32, which includes a preheating chamber 321 sleeved on the water inlet pipe 33, the preheating chamber 321 is an annular structure, a preheating cavity is opened between the inner wall and the outer wall of the preheating chamber 321, and bath liquid is filled in the preheating cavity; the heating component 32 also includes an inlet nozzle 322 and a limit seat 325 arranged on the box body 31, and an inlet pipe 323 connected to the inlet nozzle 322, The end of the inlet pipe 323 away from the inlet nozzle 322 is a ring-shaped structure, and a plurality of heating rods 324 are arranged on the inlet pipe 323; the heating rods 324 are located in the preheating chamber; a power transmission line is arranged in the inlet nozzle 322, the power transmission line is located in the inlet pipe 323 and connected to one end of the heating rod 324, and the other end of the power transmission line is connected to a power source; the limit seat 325 is in contact with the preheating chamber 321, and the inlet pipe 323 is sleeved on the limit seat 325; when After completing the proportioning of the medicine, the medicine can be injected through the injection nozzle 347, and then the medicine can fall into the medicine bin along the injection tube 341 from the gap between the drainage part 346 and the preheating chamber 321, and then turn on the power to energize the transmission line, and the energized transmission line is connected to the heating rod 324, so that the heating rod 324 is in a working state, and the temperature of the bath liquid is increased. This process occurs in the process of the nozzle body spraying clean water, and no additional preheating time is required. By increasing the temperature of the medicine, the cleaning effect of the medicine is improved, and at the same time, the precipitation of solutes can be avoided, and the concentration of the medicine can be avoided from being reduced, so that the cleaning effect becomes lower; in a further embodiment, in order to avoid the temperature of the medicine being too high, a bath liquid with a corresponding boiling point can be selected for filling, or a temperature sensor can be provided in the preheating chamber, and the bath liquid is measured by the temperature sensor, so as to avoid the temperature of the bath liquid being too high, so that the temperature of the medicine is within a certain range, and the cleaning effect of the medicine is guaranteed.

[0066] The injection assembly 34 includes an injection nozzle 347 disposed on the box body 31, an injection tube 341 connected to the injection nozzle 347, a drainage portion 346 connected to the injection tube 341 and disposed in the box body 31, and a mounting portion sleeved on the water inlet pipe 33; the drainage portion 346 is connected to the mounting portion; the mounting portion passes 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 the drainage portion 346 is connected to the preheating chamber 321. There is a gap between the heat chamber 321, and the gap is used for the circulation of medicine; a U-shaped medicine bin is formed between the inner wall of the preheating chamber 321 and the mounting portion; the mounting portion includes a support seat 342 sleeved on the water inlet pipe 33, a bearing 343 sleeved on the water inlet pipe 33 and abutting against the support seat 342, and a sealing ring located between the bearing 343 and the support seat 342; an annular protrusion is also provided in the support seat 342, and a limit spring 34 abutting against the annular protrusion 5, and an abutment tube 344 connected to the other end of the limit spring 345, the abutment tube 344 abuts against the bearing 343 away from the water inlet end of the water inlet pipe 33; the support seat 342 is an I-shaped structure, and its bottom is used to block the bottom of the preheating chamber 321; a plurality of solenoid valves 348 are provided on the support seat 342; when the agent falls into the agent bin from the gap between the drainage portion 346 and the preheating chamber 321, the bath liquid can heat the agent in the agent bin, increase the temperature of the agent, and make the temperature of the agent within a certain range. When the operator completes the preliminary cleaning of the trash can or needs to spray the agent, the solenoid valve 348 starts to work, so that the agent can be sprayed from the solenoid valve 348, and because the water flow in the water inlet pipe 33 has a certain speed, according to the Venturi effect, the agent can be mixed with the clean water or the clean water can not be transported, so that the cleaning agent or the agent can be sprayed on the trash can to complete the spraying of the agent.

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

[0068] The device is provided with a limit spring 345 in a compressed state. The elastic force generated by the limit spring 345 can apply pressure to the abutment tube 344 and the support seat 342, thereby increasing the axial pressure of the abutment tube 344 and the support seat 342 on the bearing 343. The first sealing disk 3462 is connected to the box body 31, which can also play a limiting effect on the device, thereby ensuring the stability of the device.

[0069] The water inlet pipe 33 is an integrated structure, and the water inlet pipe 33 is an axisymmetric figure, and the two ends of the water inlet pipe 33 use the line connecting the midpoints of the length of the water inlet pipe 33 as the symmetry axis; one end of the water inlet pipe 33 includes three transport pipes with different diameters, among which the largest diameter is the first transport pipe, the smallest diameter is the third transport pipe, and the remaining one is the second transport pipe, and a transition pipe for connecting the first transport pipe and the second transport pipe, and the second transport pipe is connected to the third transport pipe; wherein the bearing 343 is sleeved on the second transport pipe and abuts against the transition pipe; by setting transport pipes of different diameters, the water inlet pipe 33 can abut against the bearing 343, and by setting the sealing ring, the stability of the water inlet pipe 33 can be ensured, and the shaking of the water inlet pipe 33 under the impact of high-speed water flow can be avoided, and the collision between the water inlet pipe 33 and the medicine bin can be avoided, so as to ensure the stability of the device and avoid damage to the water inlet pipe 33.

[0070] In a further embodiment, the existing method of replenishing medicine is mostly to directly transport the medicine to the medicine bin through a pipeline. This method will cause the medicine to only impact the same position. After a long period of impact, the inner wall of the preheating chamber 321 will be damaged, which will easily lead to leakage of the bath liquid. At the same time, if the medicine is transported in the above manner, since the medicine in the pipeline has a certain initial velocity, the medicine will collide with the preheating chamber 321 during the movement, which may easily cause the medicine to scatter, resulting in a slower filling speed of the medicine bin. If the movement is carried out by using a spray nozzle body, although the transportation of the medicine can be more uniform, the diameter of the water spray port of the spray nozzle body is small, which may easily cause the spray nozzle body to be blocked, resulting in failure of the medicine transportation work.

[0071] In order to solve the above problems, the device is provided with a drainage part 346, which includes a first sealing disk 3462 arranged 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 connecting disk 3467 connected to the first sealing disk 3462; the connecting disk 3467 is provided with a plurality of water outlet holes for injecting medicine into the gap between the drainage part 346 and the preheating chamber 321; the first sealing disk 3462 is provided with a jack for inserting the injection tube 341; the second sealing disk 3463 is provided with a first channel 3464 and a second channel 3465, the first sealing disk 3462 is also provided with a third channel 3466, and the connecting disk 3467 is the bottom of the third channel 3466. The second channel 3465 is provided with multiple and evenly distributed on the second sealing disk 3463; the first sealing disk 3462 is provided with multiple connecting holes 3468 for connecting the second channel 3465 and the third channel 3466; when the medicine is transported, the medicine is transported from the injection nozzle 347 to the injection tube 341, and then the medicine follows the first channel 3464, the second channel 3465 and the connecting holes 3468, so that the medicine is located in the third channel 3466, and then the medicine falls into the gap from the water outlet on the connecting disk 3467. Compared with the traditional direct injection method, the above-mentioned device can adjust the injection speed and injection range of the medicine, avoid the medicine from being damaged by long-term high-speed impact on the medicine bin, and at the same time, compared with the nozzle body, the diameter is larger and not easy to be blocked, thereby ensuring the smooth progress of the medicine injection work.
