[0002] At present, the roadside stones or marbles removed during domestic road construction, urban construction or building construction are discarded or broken into pieces due to being old, corroded, stained with solid cement and dirt, etc. Stone is a non-renewable resource, and its restoration and reuse is a measure that benefits both the country and the people.

[0003] There are two main methods for renovating fixed stone: burning and chemical cleaning (for fixed stone surfaces). Burning, applied to fixed walls or floors, requires fuel resources that are flammable and explosive during transportation and construction. Chemical cleaning involves acid etching, requiring water rinsing. The wastewater is difficult to recycle and has certain environmental pollution emissions. Both of these methods are difficult to clean from cement residue, oil, paint, and other contaminants adhering to the marble surface.

DETAILED DESCRIPTION

[0017] The present invention will be described in detail below with reference to the accompanying drawings.

[0018] Example 1 A stone restoration system consists of three main components: a high-pressure water system, a cleaning control box, and an automatic transmission cleaning device. The high-pressure water system includes a clean water tank, an attached pump, and a sewage sedimentation and filtration tank. Its maximum operating pressure is 1000 kg and its flow rate is 50 liters per minute. It provides a sufficiently high-pressure water source to the automatic transmission cleaning device. The cleaning control box is remotely controlled from a safe visual distance of 3-5 meters from the automatic transmission cleaning device and is connected to the device's power distribution box using a waterproof control cable. The automatic transmission cleaning device includes a roller transmission mechanism 1, a positioning and adjustment mechanism 2, a jet cleaning mechanism 3, and a clamping and flipping mechanism 4, all mounted on the device frame.

[0019] The following is a detailed description of each part of the automatic transmission cleaning equipment: The roller conveyor mechanism 1 is located above the equipment frame to convey the marbles. It comprises several arranged conveyor rollers 11, connected by chains 12. These form a roller conveyor belt above the equipment frame, powered by a motor 13. The roller conveyor belt has a loading area, a positioning and adjustment area, a jet cleaning area, a clamping and flipping area, and a discharge area, depending on the direction of marble travel. Sensors are located on the equipment frame in each functional area.

[0020] The positioning adjustment mechanism 2 is located in the positioning adjustment area of the roller conveyor and is used to adjust the position of a single or multiple marbles of the same specification on the roller conveyor. Its structure comprises a pair of clamping and recovery arms 21, two slide bars 22, two positioning blocks 23, and two positioning cylinders 24. The lower ends of the two clamping and recovery arms 21 slide and are slidably connected to the two slide bars 22. The upper ends of the two clamping and recovery arms 21 extend upward from the middle of the two conveyor rollers 11 and are each equipped with a positioning block 23. The two positioning cylinders 24 are mounted opposite each other on the equipment frame, with their output ends acting on the two clamping and recovery arms 21. When the positioning sensor on the equipment frame senses that a marble has been transferred to the positioning adjustment area, the roller conveyor stops rotating, and the two positioning cylinders 24 begin to operate, pushing the two clamping and recovery arms 21 toward the center along the two slide bars 22. The two positioning blocks 23 then contact the two sides of the marble and push it to the set position (centered on the roller conveyor), completing the positioning adjustment of the marble. The positioning adjustment mechanism 2 then resets.

[0021] The jet cleaning mechanism 3 includes a first cleaning mechanism for cleaning the upper surface and front and rear sides of the marble, and a second cleaning mechanism for cleaning the left and right sides of the marble. When the marble passes through the jet cleaning area, the two cleaning mechanisms are started at the same time to complete the overall cleaning of the marble.

[0022] The first cleaning mechanism includes an electric lift assembly (I), a jet angle adjustment assembly, and a jet gun head (I) (31). The electric lift assembly (I) is used to adjust the height of the jet gun head (I) (31) according to the thickness of the marble, and the jet angle adjustment assembly is used to adjust the gun head angle of the jet gun head (31) to achieve front, back, and side cleaning. A pair of electric lift assemblies (I) are installed on opposite sides of the equipment frame. Each assembly includes a lift motor (I) (32), a turbine driven by the lift motor (I) (32), and a worm gear (33) adapted to the turbine. A lift linkage (I) (34) is installed between the turbines of the two electric lift assemblies (I) to achieve synchronization.

[0023] The jet angle adjustment component includes a screw rod 35 and a rocker arm 36 arranged in parallel one above and one below. The two ends of the screw rod 35 are installed on the upper end of the worm 33 of the two electric lifting components through brackets and bearings, and one end of the screw rod 35 is driven and controlled by a rotating motor 37. The upper end of the jet gun head 31 is movably sleeved on the rocker arm 36, and the lower end near the gun head is slidably installed on the screw rod 35. The lateral position of the jet gun head 31 is moved by rotating the screw rod 35. The swing arm 36 is mounted above the screw rod 35 via an adjustment bracket 38. The adjustment bracket 38 is provided with a semicircular slot 38a for accommodating the end of the swing arm 36. A manual adjustment lever 39 is connected to the end of the swing arm 36. The manual adjustment lever 39 can pull the end of the swing arm 36 to swing along the semicircular slot 38a to a certain angle. The manual adjustment lever 39 is provided with a pin hole, and the adjustment bracket 38 is provided with a plurality of corresponding pin holes. When the swing arm 36 is rotated to a predetermined position by the manual adjustment lever 39, the rotational position of the swing arm 36 is fixed by a plug-in fixing pin, thereby adjusting the relative position between the swing arm 36 and the screw rod 35, and further adjusting the tilt angle of the jet gun head 31 on the screw rod 35. Two positioning sensors are installed on the swing arm 36 to control the lateral movement of the jet gun head 31.

[0024] The second cleaning mechanism includes an electric lifting component 2 and a jet gun head 2 311 installed on the electric lifting component 2. The electric lifting component 2 includes a lifting motor 2 321 and a lifting screw 331 controlled by its output. The end of the lifting screw 331 is installed with the jet gun head 2 311.

[0025] The clamping and flipping mechanism 4 includes a clamping load-bearing arm 41 for supporting the marble, a lifting assembly 3 for lifting the clamping load-bearing arm 41, a clamping assembly for fixing the marble, and a flipping assembly for flipping the marble. The lifting assembly 3 includes an electric lifting side and a manual lifting side connected by a lifting linkage rod, which are installed on opposite sides of the equipment frame. The electric lifting side includes a motor and a lifting screw driven by it, and the manual lifting side includes a manual adjustment wheel 49 and a lifting screw driven by it. The two shaft ends of the clamping load-bearing arm 41 are respectively configured at the top of the two lifting screws, so that the clamping load-bearing arm 41 is driven up and down by the lifting screws. A pair of clamping assemblies are positioned opposite each other, one for clamping the marble on either side. The clamping assemblies on both sides have identical structures, including a support arm 42 fixed to a clamping support arm 41, and a clamping lever arm 43 mounted above the support arm 42 via a rotating shaft. The inner end of the clamping lever arm 43 is equipped with a clamping block 44 for clamping the marble against its upper end surface. The outer end of the clamping lever arm 43 is equipped with a clamping cylinder 45, the cylinder body of which is fixed to a fixed rod on one side of the support arm 42. The driving end of the clamping cylinder 45 is connected to the outer end of the clamping lever arm 43. A cylinder return spring 46 is also installed on one side of the clamping cylinder 45, with its lower end connected to the fixed rod and its upper end connected to the clamping lever arm 43. An oil passage is defined within the clamping support arm 41, connecting to the clamping cylinder 42. One end of the clamping support arm 41 is connected to an external hydraulic oil pipe via a universal oil inlet 48. The flip assembly includes a flip motor 47 connected to the shaft end of the clamping load-bearing arm 41. The flip motor 47 drives the shaft end of the clamping load-bearing arm 41 to flip the entire clamping load-bearing arm 41 and the marble clamped therein at the same time.

[0026] Marble restoration cleaning process: 1. Loading: Use a forklift or excavator to hydraulically clamp and load the materials (the spacing between stones of the same specification is about 15-20 cm); 2. When the roller conveyor belt delivers the marble from the loading area to the positioning adjustment area, the roller conveyor belt stops conveying, and the positioning adjustment mechanism adjusts the marble on the roller conveyor belt so that the marble is in the middle position of the roller conveyor belt. After the adjustment is completed, the positioning adjustment mechanism is reset and the roller conveyor belt continues conveying; 3. When the roller conveyor belt delivers the adjusted and positioned marble to the jet cleaning area, adjust the distance between the cleaning jet gun head and the marble cleaning surface, adjust the high-pressure water working pressure to 400-600 kg, start the first cleaning mechanism and the second cleaning mechanism to jet clean the upper surface, front and back sides, and left and right sides of the marble respectively (automatic cleaning is suitable for multiple marbles of the same specification, and manual cleaning is suitable for irregular and heavy marbles); 4. The roller conveyor belt controls the marble to make a reciprocating motion. After the first marble reaches the flipping position, it stops and the jet gun head is closed to allow the high-pressure water to flow back and release the pressure. This completes the cleaning of the left and right sides, upper surface, and front and back sides of the marble. 5. After the marble moves to the flipping position, the roller conveyor stops, and the clamping and flipping mechanism clamps and flips the marble to turn it over; 6. Turn on the jet gun head of the first cleaning mechanism, and the roller conveyor belt runs in the reverse direction to clean the last plane of the marble; 7. The cleaned marble is transported to the unloading area by a roller conveyor belt, unloaded and stacked or loaded onto trucks.
