Embodiment Construction
[0017] Below in conjunction with accompanying drawing and embodiment, further elaborate the present invention. In the following detailed description, certain exemplary embodiments of the invention are described by way of illustration only. Needless to say, those skilled in the art would realize that the described embodiments can be modified in various different ways, all without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.
[0018] Such as Figure 1 to Figure 4 As shown, the protective cover of the working head of the saline-alkali ditching machine includes a top guard plate 1 installed on the upper part of the work head (such as a rotary knife, etc.), and the front and rear ends of the top guard plate 1 are respectively inclined downward. The left and right sides of the plate 1 are respectively hinged with side guards 3 through hinges 2; t...

The invention discloses a saline-alkali soil ditcher working head protection cover which comprises a top protection plate installed on the upper portion of a working head. The front and back ends of the top protection plate are inclined towards the lower portion, and side protection plates are hinged to the left and right sides of the top protection plate through hinges; a protection space for surrounding the working head is jointly formed by the top protection plate and the side protection plates on the two sides; and field angle adjusting mechanisms for adjusting the field angles between theside protection plates and the top protection plate are arranged between the side protection plates on the two sides and the top protection plate. According to the saline-alkali soil ditcher workinghead protection cover, the field angles between the top protection plate and the side protection plates can be conveniently adjusted, the size of the protection space of a protection cover can be adjusted, and the saline-alkali soil ditcher working head protection cover can be suitable for ditcher working heads in different specifications; and the side protection plates are rotated to be adjustedto the largest height, ditching cutter replacement and maintenance can be facilitated, and operation and use are convenient.
Description
technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a protective cover for a working head of a ditching machine in saline-alkali land. Background technique [0002] Before laying underground pipes in saline-alkali land, it is usually necessary to carry out ditching operations first, and then carry out soil covering operations after laying pipes. In order to ensure the safety of the operation process and avoid the working heads such as ditching knives from causing harm to the operator, protective covers are usually arranged above and on both sides of the ditching knives to play a protective role. [0003] But after the protective cover is added, because the existing protective cover is a fixed structure, if the ditching knife needs to be replaced or repaired, the protective cover will affect the convenience of operation. Contents of the invention [0004] The technical problem to be solved by the present invention i...
