[0042] In this article, the terms "upper, lower, inside, outside" and the like are established based on the positional relationships shown in the drawings. The corresponding positional relationships may also change depending on the drawings, and therefore cannot be understood as absolute limitations on the scope of protection; moreover, relational terms such as "first" and "second" and the like are merely used to distinguish one component from another with the same name, and do not necessarily require or imply any actual relationship or order between these components.

[0043] Embodiment 1

[0044] like Figure 1 , 10 As shown in Figure 11, a telescopic cover for a soil grooving machine comprises a cover body 1 with a accommodating space 12, the cover body 1 comprises at least two sections of sub-cover bodies 11 which are nested in sequence and slidably connected, the sub-cover body 11 located at the uppermost section is connected to the telescopic mounting frame 5 of the soil grooving machine, in order to prevent the two adjacent sub-cover bodies 11 which are slidably connected from detaching from each other, an anti-detachment structure 13 is arranged between the two adjacent sub-cover bodies 11; the maximum transverse length of the accommodating space 12 is greater than the maximum transverse length of the cutting chain 4, and the minimum transverse width of the accommodating space 12 is greater than the maximum transverse width of the cutting chain 4, as long as the accommodating space 12 can enclose and accommodate the chain, in this embodiment, since part of the mud brought out by the cutting chain 4 during operation is thrown out along the running direction of the cutting chain 4, the cross-section of each sub-cover body 11 is set to be U-shaped to block the mud thrown out when the chain is running.

[0045] Specifically, the accommodating space 12 is used to accommodate the cutting chain 4, and the cover body 1 blocks the mud brought out by the cutting chain 4 to prevent the mud from splashing and to prevent the construction site and construction equipment from being contaminated by the mud; at the same time, an anti-detachment structure 13 is arranged between two adjacent sub-cover bodies 11 to prevent the sub-cover bodies 11 from detaching when sliding against each other, and the cover body 1 has the function of telescopic follow-up, and a better mud-blocking effect is achieved without manually adjusting the position of each sub-cover body 11.

[0046] Furthermore, if Fig.11 As shown, the anti-slip structure 13 includes a first stop component 131 located on the outer wall of the inner sub-cover body 11 and a second stop component 132 located on the inner wall of the outer sub-cover body 11. The two adjacent sub-cover bodies 11 are stopped and cooperated by the first stop component 131 and the second stop component 132 to prevent each other from detaching from each other; as a preferred embodiment of the present invention, the lowermost sub-cover body 11 is provided with a stop brush on the two inner side walls in the width direction of the accommodating space 12. The function of the stop brush is to prevent large pieces of soil or stones from following the cutting chain 4 upward and getting stuck in the cover body 1 or splashing mud when falling into the mud groove at a high place, wherein the stop brush can be a roller brush arranged obliquely, and the material can be a wire brush or a hard wear-resistant rubber brush.

[0047] Furthermore, if Figure 5 As shown, as a preferred solution of this embodiment, the lowermost sub-cover body 11 is the outer sub-cover body 11, and a limit stop block 14 is provided at the bottom end of the lowermost sub-cover body 11.

[0048] Furthermore, the first stopper 131 and / or the second stopper 132 can be detachably mounted on the sub-hood body 11, so as to facilitate replacement of the first stopper 131 and / or the second stopper 132; Fig.11 As shown, the first stop component 131 and / or the second stop component 132 can also be fixedly installed on the sub-cover body 11. Professional and technical personnel in this field should make corresponding settings based on their own resources and needs; a buffer pad (not shown) can be provided between the first stop component 131 and the second stop component 132 to avoid hard collision between two adjacent sub-cover bodies 11.

[0049] Furthermore, if Figure 3 , 4 As shown in Figures 6, two adjacent sub-cover bodies 11 are matched with each other through guide rails 111 and slide rails 112, wherein one sub-cover body 11 is provided with guide rails 111, and the other sub-cover body 11 is provided with slide rails 112 matched with guide rails 111.

[0050] Further, if Figure 3 , 7 As shown, in order to facilitate the installation and lifting of the sub-cover bodies 11, at least one lifting lug 3 or a lifting hole 8 is provided on the side of each sub-cover body 11.

[0051] Further, if Figure 1 , 2As shown in Figure 8, in order to facilitate the cleaning of the cutting chain 4 and the cover body 1, at least one flushing port 113 is opened on the side of at least one section of the sub-cover body 11. In order to prevent the cutting chain 4 from bringing out mud from the flushing port 113 when running, the sub-cover body 11 is also provided with a flushing door 114, which is only opened when in use. The flushing door 114 is used to close the flushing port 113. The flushing door 114 can be slidably connected, pinned or hinged to the sub-cover body 11. The specific setting should be determined by technical personnel in this field in combination with the resources they can mobilize.

The limit stop block 14 can be arranged as a retractable structure such as a spring pin (not shown). Initially, the limit stop block 14 is retracted. When the small-diameter sub-cover body 11 is inserted into the inside of the large-diameter sub-cover body 11, the limit stop block 14 extends out, and then the top cover 15 is installed. At this time, the limit stop block 14 of the middle section sub-cover body 11 extends out to stop the small-diameter sub-cover body 11 slidably connected thereto to prevent it from falling out, for example Fig. 9 The direction of the middle arrow shows a schematic diagram of the small-diameter sub-cover body 11 being inserted into the large-diameter sub-cover body 11 during the assembly process; as a preference of this embodiment, in order to facilitate the processing of the sub-cover body 11 to reduce costs, the limit stop block 14 of this embodiment can also be a pin (not shown) structure.
