The left and right sides of the upper end surface of the pretreatment base 1 are symmetrically fixedly connected with the support frames 4. The front and rear lengths of the support frames 4 are greater than the front and rear lengths of the scrapped cars outside. Two groups of support frames 4 are fixedly connected, and the two groups of support frames 4 have the same specifications. The spacing between the two groups of support frames 4 is the same as the spacing between the wheels of the scrapped cars outside. The two groups of support frames 4 can provide elevated support for the scrapped cars outside. The upper end surface of the support frame 4 is provided with anti-skid patterns. The anti-skid patterns make the upper end surface of the support frame 4 more anti-skid, so as to prevent the scrapped cars outside placed on the support frame 4 from sliding and displacing easily.

[0028] A flushing assembly 2 is arranged above the pretreatment base 1, and the flushing assembly 2 is used to flush and dry the sides, top and chassis of the scrapped cars placed on the support frame 4. A cleaning assembly 3 is arranged between the flushing assembly 2 and the filter screen plate 5, and the cleaning assembly 3 is used to clean most of the impurities blocked by the upper end surface of the filter screen plate 5 to prevent the filter screen plate 5 from being easily blocked.

[0029] The flushing assembly 2 includes a three-way valve 21, a diversion frame 22, a spray head 23, a limit through cavity 24, a displacement frame 25, a water storage cavity 26, a water guide hose 28, a circulation pump 211, a first motor 212 and a transmission lead screw 213. A limit through cavity 24 is provided on the lower side inside the pretreatment base 1. The limit through cavity 24 is matched with the displacement frame 25. The limit through cavity 24 not only facilitates the forward and backward movement of the displacement frame 25 on the lower side inside the pretreatment base 1, but also can limit the displacement frame 25 to prevent the displacement frame 25 from shaking and deviating during the displacement process.

When the circulation pump 211 is working, it can pump the water in the water storage cavity 26 into the diversion hose. A diversion hose is connected between the outlet of the circulation pump 211 and the three-way valve 21. The length of the diversion hose is twice the length of the pretreatment base 1 in the front and back directions. The diversion hose with a length twice the length of the pretreatment base 1 in the front and back directions facilitates the circulation pump 211 to transport the flushing water to the three-way valve 21. A transmission lead screw 213 is arranged on the lower side inside the pretreatment base 1. When the transmission lead screw 213 rotates forward or backward, it can drive the displacement frame 25 to move forward and backward. A first motor 212 is installed at the rear end of the transmission lead screw 213. The first motor 212 is connected to an external forward and reverse control panel through a wire. The first motor 212 can drive the transmission lead screw 213 to rotate. A water storage cavity 26 is provided inside the pretreatment base 1. An appropriate amount of clean water is stored inside the water storage cavity 26. The water storage cavity 26 enables the pretreatment base 1 to have the water storage capacity.

[0031] A hot air blower 27 is installed on the right side of the pretreatment base 1. The hot air blower 27 is connected to an external control switch through a wire. When the hot air blower 27 is working, it can blow hot air to the air guide hose 29. An air guide hose 29 is connected between the outlet of the hot air blower 27 and the three-way valve 21. The length of the air guide hose 29 is the same as that of the water guide hose 28. The air guide hose 29 can guide the hot air blown out by the hot air blower 27 to the three-way valve 21. A chamber is opened inside the guide frame 22, and the chamber is respectively connected to the spray head 23 and the three-way valve 2 1 is connected, the chamber is convenient for guiding the incoming flushing water or hot air to the multiple spray heads 23, an internal threaded through hole 251 is opened on the lower side of the displacement frame 25, and the internal threaded through hole 251 is engaged with the transmission screw 213, and the internal threaded through hole 251 facilitates the transmission screw 213 to drive the displacement frame 25 to move back and forth, and a discharge valve 11 is installed on the lower side of the right end surface of the pretreatment base 1, and the discharge valve 11 is connected to the water storage chamber 26. When the discharge valve 11 is opened, the water in the water storage chamber 26 can be discharged for replacement. Example

[0032] On the basis of the first embodiment, in this embodiment, by driving the cleaning brush roller 36 to rotate through the driving shaft 37 by the second motor 38, the rotating cleaning brush roller 36 can clean the impurities on the upper end surface of the filter screen plate 5, and at the same time, the guide frame 22 moving forward and backward will also drive the cleaning brush roller 36 to move forward and backward together, so that the rotating cleaning brush roller 36 can rotate and push the impurities blocked by the upper end surface of the filter screen plate 5 to clean them. When the impurities are pushed forward or backward to a certain distance, the guide cavity 33 will guide the filtered impurities into the collection box 32, which not only prevents the filter screen plate 5 from being easily blocked, but also can extend the cleaning cycle of the filter screen plate 5.

[0033] The cleaning assembly 3 includes a side support plate 34, a driven shaft 35, a cleaning brush roller 36, a driving shaft 37 and a second motor 38. A side support plate 34 is arranged on the left side of the lower end surface of the guide frame 22. The side support plate 34 is connected to the guide frame 22 by welding. The side support plate 34 can support and limit the left end of the driven shaft 35. A second motor 38 is installed on the right side of the lower end surface of the guide frame 22. The second motor 38 is connected to the external control panel through a wire. The second motor 38 can drive the driving shaft 37 to rotate when working. The driving shaft 37 is installed on the left end of the second motor 38. The driving shaft 37 can rotate the cleaning brush roller 36 is supported on the right end, and a cleaning brush roller 36 is installed on the left end of the driving shaft 37. The lower side of the annular side of the cleaning brush roller 36 contacts the upper end surface of the filter screen plate 5. The cleaning brush roller 36 can clean and push most of the impurities on the upper end surface of the filter screen plate 5 during its rotation. The cleaning brush roller 36 is a separately detachable structure. The detachable cleaning brush roller 36 is convenient for the later staff to replace it. A driven shaft 35 is installed on the left end of the cleaning brush roller 36, and the driven shaft 35 can support the left end of the cleaning brush roller 36, so as to ensure the rotation stability of the cleaning brush roller 36.

[0034] The pretreatment base 1 has symmetrical guide cavities 33 on both sides of the front and rear ends of the upper end. The guide cavities 33 can guide the impurities pushed by the cleaning brush roller 36 into the collection box 32. The front and rear ends of the pretreatment base 1 are symmetrically fixedly connected with extension plates 31. The extension plate 31 is connected to the pretreatment base 1 by welding. The extension plate 31 can support the collection box 32. A collection box 32 is placed on the upper end surface of the extension plate 31. The collection box 32 can collect the impurities guided out of the guide cavity 33 so that the staff can transfer and clean them in a centralized manner later. A positioning block 321 is provided at the bottom of the collection box 32. The positioning block 321 prevents the collection box 32 placed on the upper end surface of the extension plate 31 from easily shifting and slipping.

[0035] Working principle: the staff first controls the first motor 212 to rotate forward, so that the first motor 212 drives the transmission screw 213 to rotate forward together, and then the transmission screw 213 drives the guide frame 22 to move to the rear side through the displacement frame 25, and then uses an external forklift to place the external scrapped car to be processed on the support frame 4. After the placement is completed, the circulation pump 211 can be started, so that the circulation pump 211 can transport the clean water in the water storage chamber 26 to the internal chamber of the guide frame 22 through the water guide hose 28 and the three-way valve 21, and the chamber will divert the clean water to multiple spray heads 23, so that the multiple spray heads 23 can spray water outward to wash the top, side and chassis of the scrapped car placed on the upper end of the support frame 4; then the first motor is controlled When the first motor 212 is reversed, the transmission screw 213 can drive the guide frame 22 to move forward through the displacement frame 25 to perform mobile spray flushing pretreatment on the scrapped cars outside. In this process, the staff only needs to repeatedly control the forward or reverse rotation of the first motor 212 to repeatedly move the scrapped cars outside back and forth for flushing, and most of the water after flushing will flow downward and be filtered by the filter screen 5 to avoid large particles of impurities in the flushing water clogging the circulation pump 211, and the filtered water will flow into the water storage chamber 26 again for recycling, thereby reducing the clean water usage of the device; at the same time, the second motor 38 is started, so that the second motor 38 drives the cleaning brush roller 36 to rotate through the driving shaft 37 so as to rotate The cleaning brush roller 36 cleans the impurities on the upper end surface of the filter screen plate 5, and the guide frame 22 moving forward and backward will also drive the cleaning brush roller 36 to move forward and backward together, so that the rotating cleaning brush roller 36 can rotate and push the impurities blocked by the upper end surface of the filter screen plate 5 to clean. When the impurities are pushed forward or backward to a certain distance, the guide cavity 33 will guide the pushed and filtered impurities into the collection box 32, which not only prevents the filter screen plate 5 from being easily blocked, but also prolongs the cleaning cycle of the filter screen plate 5. When the scrapped car outside is washed, the staff can turn off the circulation pump 211 and turn the three-way valve 21. At this time, the outlet of the water guide hose 28 will be blocked, and the air guide hose 29 The outlet will be opened, and then the hot air blower 27 will be started, so that the hot air blower 27 can work to blow hot air to the chamber in the guide frame 22 through the air guide hose 29 and the three-way valve 21, and the chamber will divert the hot air to multiple spray heads 23, so that multiple spray heads 23 can spray hot air outward to dry the top, side and chassis of the external scrapped car after washing. In this process, the staff only needs to control the first motor 212 to rotate forward or reverse, so that the guide frame 22 can drive the multiple spray heads 23 to move forward and backward together to dry the external scrapped car. When the external scrapped car is dried, the staff moves the guide frame 22 backward into place again, and at this time, the external scrapped car that has been pre-treated by washing and drying can be forked away with the help of an external forklift.
