[0047] Specifically, a door opening 211 is formed on one side of the cleaning chamber 21 for the entry and exit of materials to be cleaned, and a door assembly capable of being opened or closed is mounted on the door opening 211. By providing the door assembly, it is avoided that cleaning liquid splashes or seeps out of the door opening 211 when the cleaning machine is working. As a preferred embodiment, the door assembly comprises a door body 24 slidingly provided on the door opening 211 and a telescopic motor 25 connected to the door body 24, the telescopic motor 25 being used to drive the door body 24 to move in the height direction, so as to switch the door opening 211 between the open state and the closed state. In the present embodiment, the door opening 211 is located below the right side of the cleaning chamber 21. The door assembly has two groups arranged side by side on the cleaning chamber 21 in the width direction, wherein the telescopic motor 25 is mounted on the side wall of the cleaning chamber 21 above the door opening 211, and is used to drive the door body 24 to move downward to block the door opening 211 to make the door opening 211 closed, or to drive the door body 24 to move upward to be located above the door opening 211 to make the door opening 211 opened. In addition, in order to facilitate observation of the cleaning situation in the cleaning chamber 21, a window 212 is also provided on one or more side walls of the cleaning chamber 21.

[0048] The mechanical arm 22 is configured to be able to move with the nozzle 23 in the height direction, the length direction and the width direction, so as to accurately clean the materials. The specific structure of the mechanical arm 22 can refer to the prior art, and the present application does not have any limitation.

[0049] As shown in Figure 6As shown, the nozzle 23 has a first channel 233, a second channel 234, a third channel 235 and a fourth channel 236 connected in sequence, wherein the first channel 233 has a liquid inlet, the fourth channel 236 has a liquid outlet, and the diameter of the first channel 233 > the diameter of the second channel 234 > the diameter of the third channel 235 > the diameter of the fourth channel 236. By setting the channels with gradually reduced diameters, the flow rate of the cleaning liquid sprayed by the nozzle 23 can be effectively improved, and the cleaning effect is better. In the embodiment, the nozzle 23 has a detachably connected nozzle body 231 and a spray head 232.

The first channel 233 is arranged in the middle region of the nozzle body 231, the second channel 234, the third channel 235 and the fourth channel 236 are arranged in the middle region of the spray head 232, and the outer diameter of the fourth channel 236 gradually decreases towards the liquid outlet direction, which facilitates the alignment or insertion of the spray head 232 into the internal channel of the material to accurately clean the material.

[0050] The high-pressure pump set 4 is arranged outside the cleaning chamber 21 and is used to supply cleaning liquid to the nozzle 23. High-pressure cleaning is especially suitable for cleaning complex structures and deep holes that are difficult to clean with ultrasonic waves. The structure of the high-pressure pump set 4 can refer to the prior art, and the present application does not make specific limitations.

[0051] The material conveying mechanism includes a turntable 3 rotatably arranged on the frame 1, a plurality of stations 31 arranged on the turntable 3, and a driving device 32 connected to the turntable 3. The turntable 3 partially passes through the door opening 211 and is located in the cleaning chamber 21, and the remaining part is located outside the cleaning chamber 21. The turntable 3 is driven to rotate by the driving device 32, so that the plurality of stations 31 thereon have a feeding state or a discharging state located outside the cleaning chamber 21 and a cleaning state located in the cleaning chamber 21. In the embodiment, the turntable 3 has four stations 31, which are arranged on the four corners of the turntable 3. The two stations 31 on the left side are located in the cleaning chamber 21, and the two stations 31 on the right side are located outside the cleaning chamber 21. When the materials on the two stations 31 on the left side are cleaned, the turntable 3 is rotated by 180° by the driving device 32, so that the materials on the two stations 31 on the left side are rotated to the outside of the cleaning chamber 21. The cleaned materials on the stations 31 can be replaced by new materials to be cleaned. At the same time, the two stations 31 on the right side have been rotated into the cleaning chamber 21 for cleaning. In this way, the feeding and discharging and cleaning can be carried out simultaneously, and the efficiency is better.

In the embodiment, the platform 3 is provided with a locking groove 34 on each of the opposite sides (left side and right side), and the locking assembly 33 is arranged on the frame 1 and located outside the locking groove 34 on the right side, and the locking assembly 33 comprises a locking tongue 331 and a driving member 332 connected to the locking tongue 331 and used for driving the locking tongue 331 to insert into the locking groove 34 to lock the platform 3 or to move away from the locking groove 34 to unlock the platform 3.

[0053] The circulating filtering area 5 comprises a filtering device 52 for filtering the cleaning waste liquid in the cleaning chamber 21 and a circulating pump 53 arranged on the liquid inlet pipeline or the liquid outlet pipeline of the filtering device 52, and the liquid outlet pipeline of the filtering device 52 is connected to the liquid inlet end of the high-pressure pump set 4. Through the circulating filtering area 5, the cleaning liquid can be reused, which is more economical and environmentally friendly.

[0054] Preferably, the circulating filtering area 5 further comprises a pre-filtering mechanism arranged between the cleaning chamber 21 and the filtering device 52, the pre-filtering mechanism comprising a pre-filtering chamber 51 in communication with the cleaning chamber 21 and a filter screen arranged between the liquid inlet end and the liquid outlet end of the pre-filtering chamber 51, and the filtering device 52 is connected to the liquid outlet end of the pre-filtering chamber 51. Through the pre-filtering mechanism, large-particle precipitates, suspended matters, floating matters and other foreign matters in the cleaning liquid can be effectively filtered out, so that the foreign matters are prevented from blocking the filtering device 52 and affecting the service life of the filtering device 52. In the embodiment, in order to improve the filtering effect, the filtering device 52 has two groups in series.

[0055] The above embodiments are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and implement it, and cannot limit the protection scope of the present application.
