DETAILED DESCRIPTION

[0019] The utility model is further described in detail below with reference to the accompanying drawings and specific implementation methods:

[0020] like Figures 1 to 6 As shown, a sewage sealed tank of a garbage truck comprises a seat 1, a garbage bin 2 arranged on the top of the seat 1, and a sewage tank 3 arranged at the bottom end of the seat 1. A vertical plate 4 is fixedly arranged on one side of the bottom end of the seat 1, and a horizontal plate 5 is detachably arranged at the bottom of the vertical plate 4. The sewage tank 3 penetrates and is fixedly arranged on the horizontal plate 5, and its top is open and the bottom is connected to a drain pipe 7 with a drain valve 6. A first hydraulic cylinder 8 is fixedly arranged horizontally on the vertical plate 4, and a motor 9 is fixedly connected to the end of the piston rod of the first hydraulic cylinder 8, and a filter frame 10 is fixedly connected to the output shaft of the motor 9. The filter frame 10 abuts against the top of the sewage tank 3 and a filter screen plate 11 is fixedly arranged inside the filter frame 10. A second hydraulic cylinder 12 is fixedly arranged on the bottom of the seat 1 at the front side of the sewage tank 3, and the piston rod of the second hydraulic cylinder 12 faces the rear side and is vertically fixedly connected to a third hydraulic cylinder 13, and the piston rod of the third hydraulic cylinder 13 faces downward and is fixedly connected to a sealing plate 14, and the sealing plate 14 can be pressed and covered on the top of the filter frame 10;

[0021] When the sewage tank 3 normally receives sewage from the garbage bin 2, the sealing plate 14 is stored in the front side of the sewage tank 3, and the filter frame 10 abuts against the top of the sewage tank 3, so that the sewage from the garbage bin 2 can be filtered first by the filter plate 11 in the filter frame 10, and then the filtered sewage falls into the sewage tank 3 for storage. When the sewage tank 3 does not need to receive sewage from the garbage bin 2, the second hydraulic cylinder 12 can be operated first to extend its piston rod, drive the sealing plate 14 to move back to the top of the sewage tank 3, and then operate the third hydraulic cylinder 13 to extend its piston rod, drive the sealing plate 14 to move down until it presses against the top of the filter frame 10, and the sewage tank 3 can be sealed, which can effectively prevent the spread of sewage odor, and is more environmentally friendly and practical. After a period of use, when the filter plate 11 is blocked, the first hydraulic cylinder 8 can be operated first to extend its piston rod, which can drive the entire filter frame 10 away from the vertical plate until the filter frame 10 is completely offset from the sewage tank 3. Then, the motor 9 is operated to drive the entire filter frame 10 to flip 180 degrees, so that the filter plate 11 can be flipped downward, and the dirt intercepted thereon can be automatically dumped down, thereby making it easier to dredge and clean the filter plate 11. The operation is simple, convenient, and more practical.

[0022] In this embodiment, a T-shaped slot 15 is provided at the bottom of the vertical plate 4, and a fourth hydraulic cylinder 16 is fixedly mounted on the side of the vertical plate 4 away from the horizontal plate 5. The piston rod of the fourth hydraulic cylinder 16 faces the slot 15 and is fixedly connected to a fixing plate 17. A plurality of fixing rods 18 evenly distributed in a rectangular array are fixed on the side of the fixing plate 17 close to the slot 15. First through holes 19 communicating with the slot 15 are provided on both the left and right sides of the vertical plate 4 corresponding to the fixing rods 18. A T-shaped plug plate 20 is fixed on one side of the horizontal plate 5. The plug plate 20 is inserted into the slot 15 and a second through hole 21 is provided at a position corresponding to the first through hole 19. The fixing plate 17 abuts against the vertical plate 4, and the fixing rods 18 penetrate and are inserted into the corresponding first through hole 19 and second through hole 21.

[0023] In actual use, the sewage tank 3 can also be flexibly replaced through the convenient disassembly and assembly between the horizontal plate and the vertical plate to meet the actual use needs. The specific replacement operation is: first operate the fourth hydraulic cylinder 16 to shrink its piston rod, drive the fixed plate 17 to retreat, until the fixed rod 18 is completely withdrawn from the first through hole 19, and then pull out the plug plate 20, so that the horizontal plate 5 can be removed from the vertical plate 4 as a whole, and the removal of the original sewage tank 3 is completed. Next, after taking the horizontal plate 5 with the new sewage tank 3, first plug the plug plate 20 on it into the slot 15, and then operate the fourth hydraulic cylinder 16 to extend its piston rod, drive the fixed plate 17 to move toward the vertical plate 4 until it presses against the vertical plate 4, so that the fixed rod 18 penetrates and plugs into the corresponding first through hole 19 and second through hole 21, and the plug plate 20 can be plugged and fixed, thereby completing the fixed installation of the new horizontal plate 5, and the installation is stable and does not affect subsequent use. In this way, the horizontal plate 5 can be conveniently disassembled and assembled, and the sewage tank 3 can be more flexibly replaced, making the overall use more flexible and convenient.

[0024] In this embodiment, the plug-in board 20 is matched with the slot 15 to ensure that the plug-in board 20 is plugged into place smoothly.

[0025] In this embodiment, the fixing rod 18 is matched with the corresponding first through hole 19 and second through hole 21 to ensure that the fixing rod 18 is smoothly inserted into place.

[0026] In this embodiment, sealing gaskets 22 are fixedly disposed on both the upper and lower parts of the filter frame 10 to ensure the sealing effect between the filter frame and the sewage tank 3 and the sealing plate 14 .

[0027] In this embodiment, a vibrator 23 is installed on the side of the filter frame 10 away from the motor 9. After the filter frame 10 is flipped 180 degrees, the vibrator 23 can be started to provide a vibration force to act on the filter plate 11, thereby realizing automatic vibration clearing of the filter plate 11, which is more convenient and practical.

[0028] In this embodiment, the inner bottom of the garbage bin 2 is V-shaped and a guide groove 24 is provided at the lowest point thereof to guide the sewage to be discharged.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
