[0042] When installing the net winding drum, first place the net winding drum on the net winding tray and adjust the distance of the net drum fixing sleeve; turn the adjusting hand wheel to make the No. 1 arm assembly and the No. 2 arm assembly rise, thereby driving the net winding tray to rise, and stop turning the hand wheel when the core of the net winding drum and the net drum fixing sleeve are on the same horizontal line; then shake the crank handle to tighten the lead screw to rotate under the drive of the bevel gear, and at the same time drive the nut sleeve to move toward the direction of the net winding drum, and the net drum fixing sleeve is inserted into the inside of the net winding drum. At the same time, the net winding drum moves toward the buckle disk under the push of the nut sleeve, and when the net winding drum is tightly fixed between the buckle disk and the net drum fixing sleeve, stop turning the crank handle, and the installation of the net winding drum is completed.

[0043] During the actual net winding operation, adjust the distance between the brake belt and the brake wheel according to the actual situation, and then adjust the friction between the brake belt and the brake wheel; avoid the net winding drum rotating too fast during the net winding operation, resulting in the net being loose when winding the grass.

[0044] Compared with the existing technology, the utility model can adjust the left and right movement of the net cylinder fixing sleeve by rotating the crank through the travel sleeve and the tightening screw, adjust the distance between the net cylinder fixing sleeve and the net winding brake seat, and facilitate the net winding sleeve to be mounted on the net cylinder fixing sleeve and clamped;

[0045] The brake belt can be used to adjust the rotation speed of the brake wheel to avoid too fast rotation, which will make the net too loose and cause the bale to be loosely wound.

[0046] The provided net winding bracket makes it convenient to place the net winding drum on the net winding tray when installing the net winding drum, and the lifting height of the net winding drum can be adjusted by turning the hand wheel, so as to facilitate docking with the net drum fixing sleeve;

[0047] The net wrapping frame has a simple structure, practical functions, and is easy to operate, and can be adapted to a variety of balers.

[0048] By arranging a sampling tube on the dilution barrel, it is convenient to take samples during the stirring process to observe the dilution condition of the paint. Whether the sampling tube is inserted depends on the specific condition of the paint.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
