Therefore, the specific structural and functional details disclosed herein are not intended to be limiting, but merely as a basis and representative basis for the claims to teach those skilled in the art to use the present utility model in substantially any suitable detailed structure in a variety of ways.

[0031] An embodiment of the present utility model provides an oil recovery vehicle, which includes a vehicle body 1 and a storage assembly 2. The storage assembly 2 includes a recovery tank 21, a piston 22, and an air extraction structure 23. The recovery tank 21 is provided with a recovery port 211 and an inner cavity 212. At least one recovery tank 21 is disposed on the vehicle body 1. The piston 22 is slidably and sealingly connected to the inner side wall of the recovery tank 21. The inner cavity 212 is communicated with the recovery port 211. The air extraction structure 23 is communicated with the inner cavity 212. The air extraction structure 23 inflates the inner cavity 212 to cause the piston 22 to rise or extracts air from the inner cavity 212 to cause the piston 22 to descend.

[0032] Combined Figure 1 and Figure 2 As shown, a storage assembly 2 is disposed on the vehicle body 1. The storage assembly 2 is composed of a plurality of recovery tanks 21. Then, combined withFigures 3 to 5 As shown in the figure, a recovery port 211 is provided on the recovery tank 21 (the recovery port 211 is preferably provided at the top of the recovery tank 21, but it can also achieve its corresponding function when provided at other positions of the recovery tank 21, and no limitation is made here). The inside of the recovery tank 21 has an inner cavity 212, and the inner cavity 212 is communicated with the recovery port 211. The piston 22 is located in the inner cavity 212 and is slidably and sealingly connected to the inner side wall of the recovery tank 21 (generally, a sealing member can be provided at the part where the piston 22 contacts the inner side wall of the recovery tank 21 to achieve the slidable and sealing connection between the piston 22 and the inner side wall of the recovery tank 21). The air extraction structure 23 is communicated with the inner cavity 212 (the air extraction structure 23 is preferably communicated with the bottom end of the inner cavity 212, but it can also achieve its corresponding function when provided at other positions, and no limitation is made here). Thus, air can be filled into the inner cavity 212 to make the piston 22 rise under the influence of air pressure, and then push the grease in a part of the inner cavity 212 above the piston 22 to flow out from the recovery port 211, or air can be extracted from the inner cavity 212 to make the piston 22 descend under the influence of air pressure, and then the grease in the mining truck is sucked into a part of the inner cavity 212 above the piston 22).

[0033] In the grease recovery vehicle of the present utility model, a storage assembly 2 is integrated on the vehicle body 1, and the rise and fall of the piston 22 are realized through the air extraction structure 23. When the piston 22 descends in the inner cavity 212 of the recovery tank 21, the grease of the mining truck can enter a part of the inner cavity 212 above the piston 22 through the recovery port 211, so that the grease is smoothly recovered and stored in the recovery tank 21; when the piston 22 rises in the inner cavity 212 of the recovery tank 21, the grease in the inner cavity 212 is discharged out of the recovery tank 21 through the recovery port 211, and the residual grease on the inner side wall of the recovery tank 21 is scraped off by the piston 22, so as to completely discharge the grease in the recovery tank 21, avoid waste caused by the adhesion of the grease on the inner side wall of the recovery tank 21, and improve the grease recovery efficiency of the grease recovery vehicle.

[0034] Further, the air extraction structure 23 includes a support block 231 and an air pipe 232. A flow - dividing cavity 2311 is provided inside the support block 231. The support block 231 is arranged on the inner bottom wall of the recovery tank 21. A flow - dividing hole 2312 communicating the flow - dividing cavity 2311 and the inner cavity 212 is provided on the support block 231, and the air pipe 232 is communicated with the flow - dividing cavity 2311.

[0035] Combined with Figures 3 to 5As shown, one end of the air pipe 232 is provided with an air pipe joint 2321, and the air pipe joint 2321 extends outside the recovery tank 21 to facilitate connection with corresponding air pump and other structures. A diversion cavity 2311 is provided inside the support block 231, and diversion holes 2312 are formed on the side wall of the support block 231. The diversion holes 2312 communicate with the diversion cavity 2311 and the inner cavity 212 of the recovery tank 21. When inflating or exhausting air through the air pipe 232, air can be smoothly inflated into or exhausted from a part of the inner cavity 212 below the piston 22.

[0036] Furthermore, the support block 231 is arranged at the center of the inner bottom wall of the recovery tank 21. The support block 231 has a cylindrical structure, and a plurality of the diversion holes 2312 are arranged at equal intervals along the circumferential direction of the support block 231.

[0037] Combined with Figure 4 and Figure 5 As shown, the bottom end of the support block 231 abuts against the inner bottom wall of the recovery tank 21. The support block 231 is located at the center of the inner bottom wall of the recovery tank 21, and the support block 231 can be fixedly connected to the recovery tank 21 by means of fasteners or welding. The overall shape of the support block 231 is similar to a cylindrical structure. The diversion holes 2312 are arranged on the cylindrical curved surface of the support block 231, and a plurality of the diversion holes 2312 are arranged at equal intervals around the circumference of the cylinder.

[0038] In this way, the arrangement of the diversion holes 2312 is relatively uniform. When inflating or exhausting air through the air pipe 232, the air pressure change around the support block 231 is also relatively uniform, which is beneficial to the stability of the piston 22 during sliding movement.

[0039] Preferably, the storage assembly 2 further includes a guide post 24. The bottom end of the guide post 24 is arranged on the support block 231. A guide hole 221 is provided on the piston 22, and the piston 22 is sleeved and slidably connected to the guide post 24 through the guide hole 221.

[0040] Combined with Figure 4 As shown, the bottom end of the guide post 24 is fixedly connected to the support block 231. The guide post 24 is usually arranged in the vertical direction, and can also be designed according to the movement track of the piston 22. A guide hole 221 is provided on the piston 22, and the guide post 24 passes through the guide hole 221, so that the piston 22 is sleeved and slidably connected to the guide post 24. Affected by air pressure, the piston 22 can slide along the guide post 24, thereby realizing the discharge and recovery of grease.

[0041] In this way, through the cooperation of the guide post 24 and the guide hole 221, the stability of the piston 22 during sliding movement is increased.

[0042] Further, the recovery tank 21 includes a tank body 213 and a mounting cover 214. The recovery port 211 is provided on the mounting cover 214. An opening 2131 is provided at the top end of the tank body 213. The mounting cover 214 is mounted on the tank body 213 to cover the opening 2131. A conical structure 241 is provided at the top end of the guiding column 24, and the tip of the conical structure 241 faces the recovery port 211.

[0043] Combined with Figure 3 and Figure 4 As shown, an opening 2131 is provided at the top end of the tank body 213. The mounting cover 214 covers the opening 2131. A conical structure 241 is provided at the top end of the guiding column 24, and the tip of the conical structure 241 faces the recovery port 211. Thus, when the grease passes through here, it is beneficial for the grease to converge towards the recovery port 211, or to be dispersed by the conical structure 241 into the inner cavity 212 around the guiding column 24.

[0044] In this way, it is beneficial for the grease to quickly enter or exit the inner cavity 212, thereby improving the grease recovery speed.

[0045] Further, the tank body 213 includes a tank body main part 2132 and a tank neck 2133 connected to the top end of the tank body main part 2132. The opening 2131 is provided at the top end of the tank neck 2133. The piston 22 includes a first slider part 222 and a second slider part 223 connected to the top end of the first slider part 222. The first slider part 222 is slidably and sealingly connected to the inner side wall of the tank body main part 2132. The second slider part 223 is used to be slidably and sealingly connected to the inner side wall of the tank neck 2133 when moving to the tank neck 2133.

[0046] Combined with Figure 4 As shown, the tank body 213 is composed of a tank body main part 2132 and a tank neck 2133. Among them, the inner diameter of the tank neck 2133 is smaller than that of the tank body main part 2132. An opening 2131 is provided at the top end of the tank neck 2133, similar to the structure of a water bottle in real life where a bottle mouth is formed at the bottleneck. The piston 22 is integrally connected by a first slider part 222 and a second slider part 223. Among them, the first slider part 222 located at the bottom realizes sliding and sealing connection with the inner side wall of the tank body main part 2132, while the second slider part 223 located at the top will only realize sliding and sealing connection with the inner side wall of the tank neck 2133 when sliding to the tank neck 2133.

[0047] In this way, through the first slider part 222 and the second slider part 223, the grease at the corresponding positions of the tank body main part 2132 and the tank neck 2133 can be discharged completely, avoiding the adhesion of grease at the tank neck 2133 and the tank body main part 2132, and improving the grease recovery efficiency.

[0048] Further, it further includes a recycling component 3. The recycling component 3 includes a connecting pipe 31 disposed on the vehicle body 1. One end of the connecting pipe 31 is connected to the recycling port 211, and the other end is used to be connected to a grease discharge port.

[0049] Combined with Figure 1 and Figure 2 As shown, the connecting pipe 31 in the recycling component 3 can select a corresponding pipeline structure according to needs, connect one end of it to the recycling port 211, and connect the other end to the grease discharge port on the mining truck through a corresponding connecting device 311, so as to facilitate the grease recycling work.

[0050] Specifically, the recycling component 3 further includes a drum 32. The drum 32 is rotatably installed on the vehicle body 1, and the connecting pipe 31 is wound around the drum 32 so that the connecting pipe 31 can be extended or retracted.

[0051] Combined with Figure 1 As shown, the drum 32 is usually rotatably installed on the mounting block 15 on the side of the vehicle body 1 to facilitate connection to the grease discharge port on the mining truck. The connecting pipe 31 is a hose that can be bent to achieve winding and is wound around the drum 32. When the grease recycling work needs to be carried out, pulling the connecting pipe 31 can drive the drum 32 to rotate, so as to realize the extension of the connecting pipe 31. The drum 32 can also be rotated in the reverse direction to retract the connecting pipe 31.

[0052] In this way, the functions of extending and retracting the connecting pipe 31 are realized through the drum 32, which is convenient for connecting to the grease discharge port of the mining truck and also convenient for storing the connecting pipe 31, improving the use convenience of the grease recycling vehicle.

[0053] Preferably, as Figure 1 and Figure 2 shown, the vehicle body 1 is provided with a first inner cabin 11 (located at the tail of the vehicle body 1) and a second inner cabin 12 (located on both sides of the vehicle body 1) to respectively accommodate the storage component 2 and the recycling component 3.

[0054] In this way, the occupied space of the storage component 2 and the recycling component 3 can be reduced, avoiding increasing the external dimensions of the grease recycling vehicle.

[0055] Further, combined with Figure 1 and Figure 2 shown, a first guard plate 13 and a second guard plate 14 are rotatably installed on the vehicle body 1 to respectively cover the first inner cabin 11 and the second inner cabin 12.

[0056] Among them, Figure 2 is the schematic diagram after the first guard plate 13 and the second guard plate 14 are closed. The first guard plate 13 rotates to cover the first inner cabin 11, and the second guard plate 14 rotates to cover the second inner cabin 12.Figure 1 This is a schematic diagram when the first guard plate 13 and the second guard plate 14 are opened, facilitating the maintenance and related work of grease recovery.

[0057] In the above-mentioned embodiments of the present invention, the descriptions of each embodiment have their own focuses. For the parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0058] For the sake of convenience in description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "above" etc. can be used here to describe the spatial position relationship between a device or feature shown in the figure and other devices or features.
