Description

Technical Field

[0001] This utility model relates to the technical field of garbage trucks equipped with leachate collection devices, and in particular to a garbage truck equipped with a leachate collection device. Background Technology

[0002] In the field of waste transportation, leachate collection devices are key components used to collect leachate generated during waste transport. They typically consist of a collection frame and are installed at the rear of the waste truck to collect dripping leachate. In existing technologies, waste leachate is mostly a viscous liquid, requiring the collection frame to be removed and emptied once full. However, due to the lack of dedicated cleaning components inside the collection frame and the high viscosity of the leachate, leachate easily remains on the inner wall of the frame after emptying, making manual cleaning difficult. Long-term leachate residue can breed bacteria, produce odors, and even affect the reusability of the collection device, increasing maintenance costs. Therefore, how to achieve convenient cleaning of the inner wall of the collection device has become a pressing technical problem to be solved in this field. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a garbage truck equipped with a leachate collection device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a garbage truck equipped with a leachate collection device, comprising a main body, a locking block slidably connected to the side of the main body, a connecting rod inserted inside the locking block, a storage tank fixedly connected to the bottom of the connecting rod, a cleaning mechanism inside the storage tank, a splash-proof device inside the storage tank, the cleaning mechanism including a rectangular guide groove formed on the inner wall of the storage tank, a threaded rod rotatably connected inside the rectangular guide groove, a scraper threadedly connected to the surface of the threaded rod, and a sealing door provided on the side of the storage tank, the sealing door being sealed to the storage tank.

[0005] The aforementioned components achieve the following effects: the scraper cleans the residual liquid inside the storage tank, thus achieving a cleaning function. When it is necessary to collect leachate from garbage, the storage tank is installed inside the locking block via a connecting rod. When it is necessary to empty the garbage from the garbage can into the main body of the vehicle, the storage tank moves to the bottom of the main body so that it does not affect the dumping of garbage. After dumping, the storage tank returns to its original position to collect the dripping leachate.

[0006] Preferably, a triangular guide block is fixedly connected to the side of the scraper, and the triangular guide block is fixedly connected to both sides of the scraper.

[0007] The effect achieved by the above components is that, under the action of the triangular guide block, the exudate can drip more easily from the surface of the scraper.

[0008] Preferably, a cleaning plate is slidably connected inside the liquid storage tank, and a scraper is fixedly connected to the side of the cleaning plate.

[0009] The effect achieved by the above components is that, under the action of the cleaning plate, the seepage on the inner wall of the storage tank can be scraped off, thereby achieving the cleaning effect.

[0010] Preferably, a fixing rod is fixedly connected inside the rectangular guide groove, and a scraper is slidably connected to the surface of the fixing rod.

[0011] The aforementioned components achieve the following effect: Under the action of the fixing rod, the scraper will not rotate with the rotation of the threaded rod. When it is necessary to clean the inner wall of the storage tank, the cleaning plate is moved down, and under the action of the scraper, the seepage on the inner wall of the storage tank can be cleaned. After cleaning, the threaded rod is rotated, causing the scraper to move. Under the action of the fixing rod, the scraper will not rotate with the rotation of the threaded rod, thereby cleaning the seepage at the bottom of the storage tank and draining it from the sealed door, thus achieving the cleaning effect.

[0012] Preferably, the splash-proof device includes a limiting groove formed in the inner wall of the liquid storage tank, a round rod fixedly connected inside the limiting groove, and a splash-proof pressure plate slidably connected to the surface of the round rod.

[0013] The effect achieved by the above components is that, under the action of the anti-splash pressure plate, the seepage liquid will not shake too much inside the storage tank, thus avoiding splashing.

[0014] Preferably, the surface of the splash guard plate is provided with through grooves, which are evenly distributed on the surface of the splash guard plate.

[0015] The effect achieved by the above-mentioned components is that, under the action of the through channel, excessively splashed seepage can be released through the through channel, thereby avoiding the splashing phenomenon.

[0016] Preferably, a rectangular plate is fixedly connected to the top of the liquid storage tank, a limiting rod is inserted into the side of the rectangular plate, a positioning plate is fixedly connected to the top of the anti-splash pressure plate, and the limiting rod is inserted into the interior of the positioning plate.

[0017] The effect achieved by the above components is that, under the action of the limiting rod, the splash guard can be limited when the splash guard is not in use.

[0018] Preferably, a return spring is sleeved on the surface of the limiting rod, and the two ends of the return spring are fixedly connected to the side of the rectangular plate and the end of the limiting rod away from the rectangular plate, respectively.

[0019] The aforementioned components achieve the following effects: Under the action of the return spring, the limiting rod is self-locking and inserted into the positioning plate, thus achieving a fixing function. When it is necessary to prevent the seepage from splashing, the splash guard plate falls naturally under the action of the round rod, allowing the splash guard plate to contact the seepage. When the garbage truck moves, the seepage will not shake excessively. Under the action of the through groove, the shaking seepage can flow out from the inside of the through groove, thereby releasing a certain amount of pressure and preventing the seepage from shaking excessively, thus avoiding splashing. Under the action of the limiting rod, the splash guard plate can be limited when not in use. Under the action of the return spring, the limiting rod is self-locking and inserted into the positioning plate, thus achieving a fixing function, thereby achieving the function of preventing splashing.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this utility model, by setting up a cleaning mechanism, when it is necessary to clean the inner wall of the liquid storage tank, the cleaning plate is moved down, and under the action of the scraper, the seepage on the inner wall of the liquid storage tank can be cleaned. After cleaning, the threaded rod is rotated to move the scraper. Under the action of the fixing rod, the scraper will not rotate with the rotation of the threaded rod, thereby cleaning the seepage at the bottom of the liquid storage tank and draining it from the sealing door, thus achieving the cleaning effect and solving the problem that it is inconvenient to clean the inner wall of the liquid storage tank.

[0026] like Figure 1 As shown, the garbage truck equipped with a leachate collection device includes a main body 1, with a sliding block connected to its lower side via a horizontal slide rail. The block has a vertically through-hole for inserting a connecting rod 5, the lower end of which is bolted to the top surface of the storage tank 4 via a flange. The storage tank 4 has an inverted trapezoidal structure with a bottom inclination angle of 15°-20°, facilitating the collection of leachate at the front sealing door 25.

[0027] The block slides between itself and the main vehicle body via a hydraulic telescopic rod (not shown in the diagram). When it is time to dump garbage, the hydraulic rod extends to lower the liquid storage tank 4 to the bottom of the main vehicle body, avoiding the unloading port. After dumping, the hydraulic rod retracts to reset the liquid storage tank to the collection position.

[0028] The mating surfaces of the connecting rod 5 and the locking block are provided with anti-slip teeth to ensure that the liquid storage tank 4 remains fixed during transportation.

[0029] Structure and function of cleaning mechanism 2:

[0030] like Figure 2-3 As shown, cleaning mechanism 2 includes dual cleaning components:

[0031] Bottom scraping assembly: Rectangular guide grooves 21 are symmetrically opened in the middle of the left and right inner walls of the liquid storage tank 4. The left end of the groove is rotatably connected to the threaded rod 22 through a deep groove ball bearing, and the right end is fixedly welded to the fixing rod 27. The two are horizontally parallel and the distance between them is 50cm.

[0032] The scraper blade 23 has an L-shaped cross-section. The vertical part has a threaded hole that engages with the threaded rod 22. The bottom surface of the horizontal part is covered with a 3cm thick rubber scraper strip, and the fitting accuracy with the bottom surface of the liquid storage tank is ≤0.5cm. A linear bearing is fitted in the middle of the scraper blade 23 and slides to connect with the fixed rod 27 to ensure that it moves only along the axial direction of the threaded rod.

[0033] The triangular guide block 24 is welded to the left and right sides of the vertical part of the scraper 23. The angle between the inclined surface of the guide block and the horizontal plane is 45°, and the bottom edge is flush with the bottom edge of the horizontal part of the scraper, forming a flow channel.

[0034] Inner wall scraping component: The cleaning plate 26 is rectangular and its top is connected to the T-shaped slide rail on the top of the inner wall of the liquid storage tank (not shown in the diagram) via a T-shaped slider, allowing it to move up and down vertically.

[0035] The scraper is made of polyurethane elastomer and is fixed to both sides of the cleaning plate 26 by countersunk screws. The scraper is 10cm thick and has an interference fit with the inner wall of the liquid storage tank with an interference of 0.2-0.3cm.

[0036] The sealing door 25 is located on the front side of the liquid storage tank and is hinged by a 316 stainless steel hinge. The door frame is fitted with a nitrile rubber sealing ring. When closed, it is locked by a latch (not marked in the diagram). The leakage rate is ≤5ml / min.

[0037] Cleaning operation steps: Open the sealing door 25, and rotate the drive threaded rod 22 (not marked in the diagram) counterclockwise using the hand crank. The scraper 23 moves to the left along the fixed rod 27 to collect the seepage at the bottom of the storage tank and discharge it through the sealing door.

[0038] Manually pull down the top handle of the cleaning plate 26 to move it vertically down along the T-shaped slide rail. The scrapers on both sides simultaneously scrape off the sticky seepage adhering to the inner wall, and the scraped liquid flows towards the sealing door at an inclined angle along the bottom surface.

[0039] After cleaning, rotate the threaded rod 22 in the opposite direction to reset the scraper 23 to the right side, and at the same time push the cleaning plate 26 to the top of the storage tank and close the sealing door 25.

[0040] The structure and function of splash guard 3: such as Figure 4 As shown, the splash guard 3 adopts a structure combining a floating pressure plate and an elastic limiter:

[0041] The limiting groove 31 is located in the middle of the left and right inner walls of the liquid storage tank. The groove is 20cm deep. A 12cm diameter round rod 32 is vertically welded inside. The lower end of the round rod is 2 / 3 of the height of the liquid storage tank from the bottom surface.

[0042] The splash guard plate 33 is rectangular and 8cm thick. It has a 12.5cm diameter sliding hole in the middle and is fitted onto the round rod 32, allowing it to slide freely along the rod. Ten guide grooves 34 are evenly distributed on the upper surface of the plate, each 5cm wide and 3cm deep, with the grooves aligned with the length of the liquid storage tank.

[0043] Limiting mechanism: A rectangular plate is attached to the edge of the top surface of the liquid storage tank. A through hole is opened in the vertical direction of the plate. A limiting rod with a diameter of 8cm is inserted into the hole. The lower end of the limiting rod is machined with a barbed boss with a height of 5cm.

[0044] The positioning plate 36 is welded to the middle of the top surface of the splash guard plate 33, and the plate has a positioning hole with a diameter of 8.5cm that matches the limiting rod 35.

[0045] The reset spring 37 is sleeved on the upper part of the limiting rod 35. The spring stiffness coefficient k = 50 N / m. The upper end is fixed to the bottom surface of the rectangular plate by screws, and the lower end abuts against the protrusion in the middle of the limiting rod.

[0046] The splash-proof function is activated:

[0047] When the liquid level in the storage tank exceeds the lower end of the round rod 32, press down the limiting rod 35 to disengage the lower end boss from the positioning plate 36. The anti-splash pressure plate 33 falls along the round rod under the action of gravity to the liquid surface with a fall distance of ≤200cm. At this time, the compression amount of the reset spring Δx=10cm, and the pre-tightening force provided makes the pressure plate stick tightly to the liquid surface.

[0048] During the garbage truck's operation, the fluctuations in the liquid surface cause the pressure plate 33 to vibrate synchronously. The guide channel 34 allows small fluctuations in the seepage to pass through while suppressing large splashes. When the liquid surface impacts the pressure plate, the pressure plate transmits the impact force to the inner wall of the storage tank through the round rod 32 to prevent liquid from overflowing.

[0049] Pull up the limit rod 35, and the return spring 37 extends to push the limit rod into the positioning plate 36. The barbed boss engages with the positioning hole, fixing the pressure plate 33 to the top of the liquid storage tank at a distance of 50cm from the top surface, without affecting the normal flow of seepage.

[0050] The liquid storage tank 4 is made of 304 stainless steel with a wall thickness of 3cm. The inner surface is electrolytically polished to a roughness of Ra≤0.8μm, which reduces the adhesion of seepage.

[0051] The main body of the scraper 23 and the cleaning plate 26 is made of aluminum alloy 6061-T6, and the contact surface is coated with a Teflon coating with a thickness of 20μm to reduce frictional resistance and liquid adhesion.

[0052] The sealing ring of the sealing door 25 is made of fluororubber FKM, which is resistant to temperature from -20℃ to 200℃; the return spring 37 has a galvanized surface and a salt spray test of ≥1000 hours.

[0053] Usage Process and Technical Effects

[0054] Leakage collection mode: The storage tank 4 is fixed to the side of the main vehicle body by a locking block, and the top opening is aligned with the leakage port at the bottom of the garbage truck compartment. The leakage falls freely into the tank, and the anti-splash pressure plate 33 is in the top locked state.

[0055] Unloading avoidance mode: The hydraulic telescopic rod drives the liquid storage tank to descend to the bottom of the main vehicle body with a stroke of 300cm, completely avoiding the unloading port, and automatically resets within 5 seconds after unloading is completed.

[0056] Automatic cleaning mode is optional: An electric drive module can be added: the threaded rod 22 is driven by a 20W DC geared motor, and the cleaning plate 26 is pushed and pulled by a micro cylinder with a stroke of 150cm. The cleaning process can be triggered by one button through the vehicle control system, and the whole process takes ≤2 minutes.

[0057] The operating principle is as follows: When using a garbage truck equipped with a leachate collection device, the operating procedure is as follows:

[0058] S1. Installation of the storage tank and leakage collection

[0059] Installation and positioning: Insert the liquid storage tank 4 vertically into the locking block on the side of the main vehicle body 1 through the connecting rod 5, and fix it through the limiting structure of the locking block, so that the top opening of the liquid storage tank is aligned with the seepage dripping position at the bottom of the garbage truck.

[0060] Unloading avoidance: When it is necessary to dump the garbage in the garbage can, the block drives the liquid storage tank 4 to slide down to the bottom position along the side of the main body 1, avoiding the unloading port and avoiding affecting the normal dumping of garbage; after dumping, the liquid storage tank automatically resets to the collection position to continue to receive the dripping leachate.

[0061] S2. Cleaning operation of the inner wall of the storage tank

[0062] Cleaning the inner wall scratches: Slide the cleaning plate 26 downwards. The scraper on its side fits tightly against the inner wall of the liquid storage tank 4. The cleaning plate can be moved vertically along the inner wall by manual or mechanical drive such as a cylinder to scrape off the sticky seepage to the bottom of the liquid storage tank.

[0063] Bottom liquid removal: Rotate the threaded rod 22 to move the scraper 23 horizontally along the fixed rod 27. The fixed rod restricts the scraper's rotation, allowing only axial movement. The rubber strip at the bottom of the scraper collects the seepage from the bottom of the storage tank to the sealing door 25. Opening the sealing door allows the waste liquid to be discharged.

[0064] The function of the triangular guide block 24: The triangular guide blocks on both sides of the scraper form a guide slope to guide the seepage liquid to flow quickly to the sealing door and avoid leaving residue on the scraper surface.

[0065] S3, Activation and Locking of Splash Protection Device

[0066] Splash prevention mode activated: Press down on the limiting rod 35 to disengage it from the locking hole of the positioning plate 36. Under the action of gravity, the splash prevention plate 33 falls freely along the round rod 32 to the surface of the seepage. At this time, the splash prevention plate suppresses the liquid surface with its own weight, inhibiting the large sloshing of the seepage during the garbage truck's movement.

[0067] The function of the guide groove 34: The guide grooves evenly distributed on the surface of the pressure plate allow the seepage liquid with small swaying to pass through, release the liquid surface pressure, and avoid splashing.

[0068] Non-working state locking: Pull up the limit rod 35, and under the elastic force of the return spring 37, the limit rod is inserted into the locking hole of the positioning plate 36, fixing the anti-splash pressure plate 33 to the top of the liquid storage tank, without affecting the normal collection of seepage.
