[0026] S3. Install the dust hood and connect one end of the protective mesh tube to the dust hood;

[0027] S4. Install the bite block, plug the bite block into the steel frame and install the fastening bolts.

[0028] In summary, the beneficial effects of the present invention are:

[0029] 1. By installing a protective mesh tube inside the box body, and positioning one end of the protective mesh tube through a sleeve and the other end through a constricting tube body, the fan tube body can be quickly sleeved on the outside of the protective mesh tube during vehicle assembly, and the fan tube body and the protective mesh tube can be tightly fitted and installed inside the dust cover through a threaded seat, a threaded rod and a clamping ring. Different from the cleaning vehicle in the prior art, the fan tube body does not directly connect with the garbage, thereby avoiding the problem of garbage such as broken metal pieces, nails, sharp stones, etc. piercing the fan tube body to cause unstable wind pressure and garbage leakage;

[0030] 2. In order to clean the inside of the protective mesh tube and avoid rust problems caused by long-term contact with garbage carrying liquids, an injection groove is opened on the inner wall of the protective mesh tube for cleaning liquids such as rust remover or rust removal oil to enter the protective mesh tube. A tank is specially provided in the box body to store cleaning liquid. When the cleaning work of the cleaning vehicle is completed, the fan stops sucking. At this time, the internal state of the protective mesh tube is converted from negative pressure to normal pressure. At the same time, the booster pump starts working and cooperates with the liquid extraction pipe to pump the cleaning liquid in the tank to the atomizing nozzle. At the same time, the fan restarts and generates positive pressure, so that the protective mesh tube is in a positive pressure environment. In the process of blowing from the air duct to the dust hood, the movable plate will be driven to rotate in the direction of the dust hood in cooperation with the rotating shaft. At this time, the sealing protrusion is separated from the injection groove, and the atomizing nozzle sprays the cleaning liquid into the injection groove and covers the entire protective mesh tube along with the air duct;

[0031] 3. In order to improve the efficiency of rust removal, an air supply mechanism is provided in the box body. The air supply pipe is used to connect with the one-way valve of the car ventilation to introduce the hot gas that should be directly discharged into the heat source box. During the operation of the cleaning vehicle, the solenoid valve is in an open state. The hot gas that enters the heat source box through the air supply pipe will be directly discharged out of the box body. When the protective isolation mesh pipe needs to be cleaned, the solenoid valve is closed. At this time, the hot gas cannot be discharged. At the same time, the fan generates positive pressure wind into the protective isolation mesh pipe, and a part of the normal temperature wind will enter the heat source box along the air inlet one-way valve and mix with the hot gas, and the one-way air will be discharged from the only outlet. The valve discharge enters the protective mesh tube, and the atomizing nozzle continuously sprays out the cleaning liquid in atomized form. The hot gas carries the atomized cleaning liquid to cover the entire protective mesh tube. When the internal temperature of the protective mesh tube rises, the reaction speed of the cleaning liquid is accelerated. Combined with the different thermal expansion coefficients of the rust and the base protective mesh tube, the rust will bulge and crack, thereby accelerating the peeling off from the protective mesh tube, thereby achieving the self-cleaning effect of the protective mesh tube, which can not only solve the problem of damage to the fan tube body, but also avoid the problem of maintenance of the protective mesh tube due to rust, thereby improving the reliability and durability of the protective mesh tube.

[0045] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0046] like Figures 1 to 11As shown, in embodiment 1 of the present invention, after the box body 4 is connected to the steel frame 1 through the Z-shaped bracket 3 and the slide block 2, the first electro-hydraulic rod is installed inside the first mounting groove 24, and the piston rod end of the first electro-hydraulic rod is arranged along the direction of the sleeve 5. At the same time, the piston rod end of the first electro-hydraulic rod is welded to the outer bottom wall of the top plate of the Z-shaped bracket 3. The first electro-hydraulic rod can drive the box body 4 and the connecting parts to rise and fall, which can avoid damage to the dust hood 9 caused by bad road conditions.

[0047] After the box body 4 is installed, the fan tube body is positioned through the sleeve 5 and the protective partition tube 6 on the top of the box body 4 to locate the installation position of the fan tube body, and the fan tube body is inserted into the sleeve cavity 7 formed between the sleeve 5 and the protective partition 6. The fan sleeve extends along the cylindrical protective partition 6 and passes through the box body 4 and the convergence tube body 8 in sequence, and finally moves to the inside of the cover body 91. At this time, one end of the protective partition 6 and the fan tube body are both located at the top of the sleeve 5 and can be fixed by tying or bonding, and are adapted to be connected to the fan through external parts, and the other end is moved to the inside of the cover body 91. At this time, the movable baffle 90 is opened and the threaded rod 94 is rotated to make it rotate inside the threaded seat 93. The two threaded rods 94 drive the two clamping rings 95 to move and make the fan tube body and the protective partition tube 6 They are tightly clamped and fit together. The two "C"-shaped clamping rings 95 can be firmly clamped on the outside of the fan tube body and the protective partition mesh tube 6 when fitted together, and the inner wall of the clamping ring 95 is fixed with a rubber pad. The rubber pad is used to increase the friction of the fitting surface to prevent the fan tube body from loosening and detaching. After fitting, the protective partition mesh tube 6 and the fan tube body are located in the gap between the two flow limiting baffles 92 to ensure that the garbage is sucked into the protective partition mesh tube 6 and the fan tube body along the flow limiting baffles 92. Compared with the prior art method of directly connecting the dust hood 9 and the fan through the fan tube body, this solution actually provides the inner wall of the fan tube body with an extra layer of stainless steel material, which plays a significant protective role without affecting the suction of the fan, and prevents the fan tube body from being damaged by sharp objects.

[0048] The first electro-hydraulic rod is used to achieve the self-locking positioning effect of the box body 4, and the first electro-hydraulic rod can correspondingly drive the box body 4 to rise and fall so that the components connected to the box body 4 can be lifted and lowered together. When the road condition is poor, the box body 4 and the dust hood 9 and other connecting components are raised to avoid it, and it falls back when cleaning the garbage. In addition, in order to expand the dust suction area without installing a side suction, the dust hood 9 is widened compared with the prior art, thereby increasing the dust suction range without installing a side suction. In order to prevent the garbage from entering the dust hood 9 and causing garbage accumulation due to the blind spot in the adsorption range, the dust hood 9 includes a hood body 91, and two movable baffles 90 are detachably installed on the top of the hood body 91. The inner wall of the hood body 91 is provided with two flow limiting baffles 92, so as to limit the suction direction of the garbage. After the garbage enters the dust hood 9, the flow limiting baffle 92 can guide the garbage, and the garbage is concentrated in the dust suction range of the protective partition pipe 6 and the fan pipe body for treatment.

[0049] like Figures 1 to 11 As shown, in Example 2 of the present invention, on the basis of Example 1, in order to prevent the protective mesh tube 6 from rusting, a liquid spraying assembly 270 is movably installed inside the box body 4, and the liquid spraying assembly 270 includes a booster pump 28, and the water inlet of the booster pump 28 is fixedly connected to a liquid extraction pipe 30, and the liquid outlet of the booster pump 28 is fixedly connected to an atomizing nozzle 29 for atomizing the liquid medicine, and the atomizing nozzle 29 is fixedly installed on the outer wall of the tank body 27, and the cover plate 41 is opened to plug the tank body 27 and the bracket 26, and the fan pipe body that fits at the injection groove 36 is expanded, and the atomizing nozzle 29 is fitted with the injection groove 36 after the expansion, and the movable part 300 arranged in the protective mesh tube 6 plays a role in controlling the opening and closing of the injection groove 36 in the protective mesh tube 6. When the small positive magnetic When the iron 35 is attracted to the small negative pole magnet 34, the protrusion 33 on the movable plate 32 will block the injection groove 36 to prevent the liquid from flowing out. Correspondingly, when the protrusion 33 is opened, the injection groove 36 can be used to spray the liquid. The injection groove 36 will be blocked by the sealing protrusion 33 under the normal pressure and negative pressure of the protective partition 6. The rotating shaft 31 drives the movable plate 32 and the sealing protrusion 33 to fit with the injection groove 36. The arc plate 37 can prevent garbage or liquid from entering the protective partition 6 and then backflowing or blocking the injection groove 36. The cover plate 41 provides space for maintaining the interior of the box body 4, and a pipe nozzle for replenishing liquid is set on the top of the box body 4, through which rust remover and other rust removal liquid can be injected, and the rust removal liquid will be stored in the tank body 27.

[0050] At the same time, an air supply mechanism 38 is fixedly installed inside the box body 4, and the air supply mechanism 38 includes a heat source box 380. An air supply pipe 381 is fixedly installed on the inner wall of the heat source box 380, and the other end of the air supply pipe 381 is used to connect with the vehicle compartment ventilation one-way valve to introduce the heat in the vehicle compartment into the heat source box 380. When the vehicle is running, the heat in the vehicle compartment will be discharged to the outside of the vehicle through the vehicle compartment one-way valve. By adding the air supply mechanism 38, the heat in the vehicle compartment is transported to the heat source box 380 for temporary storage instead of being directly discharged from the vehicle compartment, which is convenient for rust removal. In order to prevent the air pressure accumulated inside the heat source box 380 from being too high, an electromagnetic valve 382 for discharging the heat source is fixedly installed on the inner wall of the heat source box 380, and the end of the electromagnetic valve 382 away from the heat source box 380 passes through the box body 4 and extends to the outside of the box body 4. When the electromagnetic valve 382 is opened, the hot gas entering the heat source box 380 will be directly discharged outside the box body 4. At this time, the functions of the heat source box 380 and the solenoid valve 382 are consistent with the effect of the carriage one-way valve, and the side of the heat source box 380 away from the solenoid valve 382 is detachably installed with an air inlet one-way valve 383 and an air outlet one-way valve 384 that penetrate the protective partition mesh tube 6 and extend to the inside of the protective partition mesh tube 6. Two holes are provided on the fan tube body and the side of the protective partition mesh tube 6 away from the injection groove 36, which are respectively used to connect the air outlet one-way valve 384 and the air inlet one-way valve 383. The air inlet one-way valve 383 is used to receive the positive pressure gas generated by the fan, and the air outlet one-way valve 384 is used to guide the hot gas inside the heat source box 380 to the inside of the protective partition mesh tube 6. Because the solenoid valve 382 is set close to the air supply pipe 381, when the solenoid valve 382 is in the open state, the hot gas will be discharged immediately through the solenoid valve 382 after entering the inside of the heat source box 380, and will not enter the protective partition mesh tube 6 through the air outlet one-way valve 384.

[0051] When it is necessary to remove rust and clean the protective isolation mesh tube 6, the fan switches from negative pressure suction air to positive pressure outlet air. When the interior of the protective isolation mesh tube 6 is in a positive pressure state, normal temperature air will enter the heat source box 380 through the air inlet check valve 383, and when the solenoid valve 382 is closed, the mixed air can only be discharged through the air outlet check valve 384. In addition, since the setting position of the air outlet check valve 384 is located below the air inlet check valve 383, it can ensure that the positive pressure wind direction generated by the fan enters the heat source box 380 through the air inlet check valve 383 and is fully mixed with the heat source before being discharged through the air outlet check valve 384. At the same time, due to the change in wind direction, the rotating shaft 31 will drive the movable plate 32 to rotate. At this time, the end of the movable plate 32 with the sealing protrusion 33 will contact with the The injection groove 36 is separated, and the other end of the movable plate 32 is in contact with the inner wall of the protective partition mesh tube 6. After the booster pump 28 is started, the liquid extraction pipe 30 will pump the rust removing liquid in the tank body 27 to the atomizing nozzle 29. The atomizing nozzle 29 atomizes the rust removing liquid and sprays it into the interior of the protective partition mesh tube 6 through the opened injection groove 36. At this moment, the air duct in the protective partition mesh tube 6 is blown out from the direction of the sleeve 5 along the direction of the dust hood 9, and the mixed hot gas flowing out from the inside 384 is mixed with the air duct and entrained with the medicine mist. Since the outside of the protective partition mesh 6 is covered with a fan pipe body, the heat source will not be directly lost, and can be quickly gathered to heat up the inside of the protective partition mesh 6. The heated rust removing liquid has a better rust removing effect, thereby improving the rust removing efficiency of the rust removing liquid.

[0052] like Figures 1 to 11As shown, in Example 3 of the present invention, based on any one of Examples 1 and 2, two bite blocks 10 are connected to the steel frame 1 by bolt threads, a second electro-hydraulic rod is installed in the mounting seat plate 25 on the inner wall of the steel frame 1 and fixed by bolts, and at the same time, the piston rod end of the second electro-hydraulic rod is connected to the driven component 16, and the driven component 16 includes a mounting cylinder 162, and the piston rod end of the second electro-hydraulic rod is inserted into the inside of the mounting cylinder 162 and then welded or bolted, and the driven component 16 also includes a The two ends of the second rotating shaft rod 161 are respectively inserted into the inside of the two second rotating shaft seats 160, and the two rotating shaft seats 160 are fixedly connected to the front guard plate 17, and the two first rotating shaft seats 180 and the two limiting plates 182 are also fixedly connected to the front guard plate 17. The first rotating shaft rod 181 is movably installed on the opposite side of the two first rotating shaft seats 180. The first rotating shaft rod 181 penetrates and connects the two limiting plates 182 and the transmission plate 15. At the same time, the opposite side of the two bite blocks 10 The two sides are fixedly installed with a rod-shaped rotating shaft seat 14, and an axle rod is set at the opposite end of the two rod-shaped rotating shaft seats 14. A transmission plate 15 is fixedly installed on the outside of the axle rod. When the piston rod end of the second electro-hydraulic rod drives the mounting tube 162 to contract, the transmission plate 15 cooperates with the follower to drive the front guard plate 17 to tilt upward. Correspondingly, when the piston rod of the second electro-hydraulic rod is extended, the transmission plate 15 and other components drive the front guard plate 17 to rotate and present a vertical angle, and the rotating plate 11 installed on the outside of the pin shaft 12 is respectively connected to the front guard plate 17 and the protection component 13. Therefore, when the front guard plate 17 rotates, the pin shaft 12 cooperates to rotate and drives the rotating plate 11 and the protection component 13 to rotate together, which is used to control the side brush mechanism installed in the protection component 13, and the angle adjustment is consistent with the first electro-hydraulic rod controlling the dust hood 9. When encountering complex road sections, the first electro-hydraulic rod and the second electro-hydraulic rod control the dust hood 9 and the side brush installed in the protection component 13 to lift up to avoid direct contact with the ground, so as to achieve the purpose of protection through complex road sections.

[0053] The mounting seat 130 and the mounting groove 131 can not only install the driving motor but also play a protective role, and the annular anti-collision guard ring 132 can also protect the side brush, thereby avoiding the garbage cleaning vehicle from collision and damage due to line of sight and distance problems during operation. In addition, the cleaning vehicle cockpit usually adopts a wide-angle glass structure to expand the field of vision, and the width between the two anti-collision guard rings 132 is consistent with the dust hood 9. During driving, the anti-collision guard ring 132 can be observed to determine whether the dust hood 9 will have a collision problem.

[0054] like Figures 1 to 11As shown, in Example 4 of the present invention, on the basis of any one of Examples 1 to 3, two pads 22 are fixedly installed on the top of the steel frame 1, and the pads 22 are connected to the steel frame 1 by bolts and can be disassembled, and can be used to raise the distance between the cleaning vehicle accessories and the steel frame 1, providing space for height adjustment to adapt to garbage bins of different sizes and specifications. Two second mounting grooves 23 are opened inside the steel frame 1, and a support frame 19 is fixedly installed on the inner wall of the steel frame 1. The shape of the support frame 19 is an "I" shape, and a third electro-hydraulic rod is installed on the top of the support frame 19, and the end of the third electro-hydraulic rod is passed through the second mounting groove 23 and fixedly connected to one end of the bottom of the garbage bin to control the dumping angle of the garbage bin part. When the third electro-hydraulic rod pushes one end of the bottom of the garbage bin, the garbage bin will be tilted to help the discharge of garbage. The corresponding garbage bin and fan structure are consistent with the prior art, and both use the principle of negative pressure suction by the fan to suck garbage into the garbage bin and store it.

[0055] Embodiment 5 of the present invention discloses a process for installing a frame of a sweeper based on any one of embodiments 1 to 4. The process for installing a frame of a sweeper comprises the following steps:
