Description

Technical Field

[0001] This utility model relates to the field of cleaning machine technology, specifically to a multi-nozzle collaborative working device for a cleaning machine. Background Technology

[0002] Traditional cleaning machines typically use a single nozzle or a few nozzles for cleaning, which has some limitations. Single-nozzle cleaners have low cleaning efficiency, and require a long time to complete the cleaning task when cleaning large areas or objects with complex shapes. Furthermore, the cleaning angle of a single nozzle is limited, easily creating blind spots and resulting in some parts of the object's surface not being effectively cleaned.

[0003] To improve cleaning efficiency and quality, multi-nozzle cleaning machines have emerged. Currently, most machines use mechanical linkage mechanisms to drive the nozzles to adjust their angle or position, which cannot achieve full automation. Furthermore, since some nozzles are jet nozzles, they have a large reverse impact force, which can cause the support frame to bear a huge external force. If this external force exceeds the elastic limit of the support frame material for a long time, the support frame will undergo plastic deformation, changing its original shape and structure, and affecting its support effect and stability for the nozzles. Utility Model Content

[0004] Therefore, this utility model proposes a multi-nozzle collaborative working device for a cleaning machine to solve the problems mentioned in the background art.

[0007] The screw has one end connected to a bearing and is driven by a forward and reverse motor fixed on a mounting base.

[0009] An adjusting seat has a through hole through which a threaded ring is inserted, and the adjusting seat is fixed to the threaded ring;

[0010] The number of adjusting beams is the same as that of the U-shaped joints. One end of each adjusting beam can be rotatably installed in the corresponding U-shaped joint, and the other end of each adjusting beam is fixed with a mounting seat for installing a jet nozzle.

[0011] And a buffer support mechanism, which is the same number as the adjusting beam, and is installed on the adjusting seat. Each buffer support mechanism and the first ear seat on the corresponding adjusting beam are rotatably connected by a pull rod.

[0012] Furthermore, preferably, the straight-line distance between any two adjacent U-shaped connectors is set to be the same.

[0013] Furthermore, preferably, the buffer support mechanism includes:

[0014] The bottom end of the second ear seat is slidably disposed in the first sliding opening of the adjusting seat, and the top end of the second ear seat is rotatably connected to the pull rod;

[0031] With reference to the accompanying drawings of the embodiments of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below.

[0032] Example: Please refer to the appendix. Figure 1-4 This utility model provides a technical solution: a multi-nozzle collaborative working device for a cleaning machine, comprising:

[0033] The fixing seat 6 has three end corners, and a U-shaped connector 5 is fixed at each end corner of the fixing seat 6. A bearing 7 is installed in the middle hole of the fixing seat 6.

[0034] The screw 8 has one end connected to the bearing 7 and is driven by the forward and reverse motor 4 fixed on the fixed base 6;

[0035] Threaded ring 14, which is threadedly connected to the threaded surface of screw 8;

[0036] The adjusting seat 13 has a through hole through which the threaded ring 14 passes, and the adjusting seat 13 is fixed to the threaded ring 14;

[0037] The number of adjusting beams 3 is the same as that of U-shaped joints 5. One end of each adjusting beam 3 can be rotatably installed in the corresponding U-shaped joint 5. The other end of each adjusting beam 3 is fixed with a mounting seat 2 on which the jet nozzle 1 is installed.

[0038] And a buffer support mechanism, which is the same number as the adjusting beam 3, and is installed on the adjusting seat 13. Each buffer support mechanism and the first ear seat 9 on the corresponding adjusting beam 3 can be rotatably connected with a pull rod 10.

[0039] It should be emphasized that the number of adjusting beams 3 is determined by the number of jet nozzles to be installed, and multiple adjusting beams 3 need to be arranged in an array along the circumferential direction of the screw 8 to achieve coordinated adjustment.

[0040] In this embodiment, the straight-line distance between any two adjacent U-shaped connectors 5 is set to be the same.

[0041] In this embodiment, the buffer support mechanism includes:

[0042] The bottom end of the second ear seat 11 is slidably disposed in the first sliding opening 15 of the adjusting seat 13, and the top end of the second ear seat 11 is rotatably connected to the pull rod 10.

[0043] The first slider 23 is slidably disposed in the first sliding cavity 16 which is connected to the first sliding opening 15, and the first slider 23 is fixedly connected to the second ear seat 11.

[0044] The second slider 20 is slidably disposed within the second sliding cavity 17 of the adjusting seat 13;

[0045] Compression spring 19, there are two of them, and they are respectively located on the left and right sides of the second slider 20;

[0047] Specifically, when the jet nozzle is working, the second ear seat 11 moves backward due to the reverse impact force it generates. This indirectly drives the second slider 20 to move to the right through the first slider 23 and the connecting block 21. The compression spring on the right side counteracts the reverse impact force of the jet nozzle through its own elasticity, thus buffering the backward movement of the second ear seat and reducing fatigue support for the device of the present invention.

[0048] It should also be noted that when the jet nozzle stops working, the compression spring on the right side rebounds, while the compression spring on the left side partially cancels out the rebound force to avoid rebound damage.

[0049] In this embodiment, the length and width of the second slider 20 are both greater than the length and width of the connecting block 21.

[0050] In this embodiment, the sliding distances of the connecting block 21 and the first sliding cavity 16 are the same.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
