Threaded holes are provided at the four corners of the top of the connecting seat 1, allowing it to be fixedly connected to the bottom of the belt conveyor using bolts. A telescopic adjustment mechanism 2 is provided on the surface of the connecting seat 1. The telescopic adjustment mechanism 2 includes a bidirectional threaded rod 21, with two sets of opposite threads on its surface. A connecting block 22 is threaded through and connected to the surface of the bidirectional threaded rod 21. Rotating the bidirectional threaded rod 21 causes the two sets of connecting blocks 22 to move closer together or further apart. A connecting rod a23 is hinged to the upper end of the outer sidewall of the connecting block 22. The movement of the connecting blocks 22 causes the connecting rod a23 to move closer together or further apart. A gear is provided at the end of the connecting rod a23 away from the connecting block 22, and the gear ends of the two sets of connecting rods a23 mesh with each other. A connecting rod b24 is hinged to the lower end of the outer sidewall of block 22. When connecting rods a23 move closer or further apart, they will synchronously drive connecting rod b24 to move closer or further apart. A gear is provided at the end of connecting rod b24 away from connecting block 22. The gear ends of the two sets of connecting rods b24 mesh with each other. An upper fixed seat 25 is hinged to the end of connecting rod a23 away from connecting block 22. The lower surface of connecting seat 1 is fixedly connected to the upper surface of upper fixed seat 25. A lower fixed seat 26 is hinged to the end of connecting rod b24 away from connecting block 22. A connecting frame 210 is fixedly connected to the bottom end of the outer wall of lower fixed seat 26. When the two sets of connecting rods move closer or further apart, they will synchronously drive upper fixed seat 25 and lower fixed seat 26 to move synchronously. Upper fixed seat 25 and lower fixed seat 26 will synchronously drive connecting seat 1 and connecting frame 210 to move closer or further apart, achieving the effect of synchronously driving telescopic seat 27 and sliding block 28 to adjust length.

[0036] Reference Figure 1 and Figure 4 - Figure 5 The connecting frame 210 is threadedly connected to the sliding block 28 via a fixing bolt 29. The side wall of the connecting frame 210 has a threaded groove, through which the fixing bolt 29 passes and is threaded into the inner threaded groove of the outer side wall of the connecting frame 210. The side wall of the sliding block 28 also has a threaded groove, through which the fixing bolt 29 passes and is threaded into the inner threaded groove of the sliding block 28. The fixing bolt 29 is self-locking, allowing the sliding block 28 to be fixed to the connecting frame 210. The outer side wall of the connecting frame 210 has a groove, and the side wall of the sliding block 28... The sliding block 28 is provided with a protrusion, and the protrusion is slidably connected to the groove of the connecting frame 210. The function of the groove of the connecting frame 210 is to limit and guide the sliding block 28, so that the sliding block 28 can only slide up and down within the groove of the connecting frame 210. The outer side wall of the sliding block 28 is slidably connected to the telescopic seat 27. The length of the support leg can be adjusted by adjusting the telescopic seat 27 to adapt to different terrains. The upper surface of the telescopic seat 27 is fixedly connected to the lower surface of the connecting seat 1. The surface of the sliding block 28 is provided with a support mechanism 3.

[0037] Reference Figure 1 and Figure 6 - Figure 7The support mechanism 3 includes a cylindrical rod 31, with a sliding plate 32 fixedly connected to the bottom end of the cylindrical rod 31. The cylindrical rod 31 fixes the sliding plate 32. An inverted triangular groove is formed on the surface of the sliding plate 32. A sliding rod 38 is slidably connected to the inner wall of the inverted triangular groove of the sliding plate 32. The sliding rod 38 can move closer together or further apart by sliding within the inverted triangular groove. Two sets of support blocks 33 are slidably connected to the surface of the sliding plate 32. A positioning block 37 is slidably connected to the upper surface of the support block 33. The outer sidewall of the positioning block 37... The support block 33 is fixedly connected to the outer sidewall of the sliding block 28. A protrusion is provided on the top of the support block 33, and a groove is provided at the bottom of the positioning block 37. The protrusion of the support block 33 is slidably connected to the groove of the positioning block. The groove serves to limit and guide the support block 33, ensuring that it can only move back and forth within the groove of the positioning block 37. A slot is formed on the surface of the support block 33. The outer sidewall of the wedge block 34 contacts the slot on the surface of the support block 33. The arc-shaped front end of the wedge block 34 allows the telescopic leg 36 to be pulled outward in one direction, and the slot of the support block 33 is also present. The groove compresses the arc surface of the wedge 34. The telescopic leg 36 has a cavity, and the wedge 34 is slidably connected within the cavity of the telescopic leg 36. The cavity of the telescopic leg 36 serves to limit and guide the wedge 34, ensuring that the wedge 34 can only slide back and forth within the cavity of the telescopic leg 36. The top surface of the cylindrical rod 31 is fixedly connected to the inner side wall of the telescopic seat 27. The cylindrical rod 31 passes through and is slidably connected to the inner wall of the sliding block 28. The cylindrical rod 31 serves to fix the sliding plate 32. The sliding plate 32 is slidably connected to the inner side wall of the sliding block 28. The surface of the support block 33 is provided with an inverted triangular groove. The inner side wall of the support block 33 is slidably connected to a telescopic leg 36. The length of the telescopic leg 36 can be adjusted by sliding on the inner side wall of the support block 33. The telescopic leg 36 is elastically connected to a wedge block 34 through a spring 35. One end of the spring 35 is fixedly connected to the bottom end of the wedge block 34, and the other end of the spring 35 is fixedly connected to the inner side wall of the telescopic leg 36. The function of the spring 35 is to automatically reset the wedge block 34 after it has moved, so that the wedge block 34 can be re-engaged with the groove on the surface of the support block 33 to complete the fixation.

[0038] Working principle: When using this equipment, if the underground ground is uneven, the length of the telescopic leg 36 can be adjusted by adjusting the telescopic adjustment mechanism 2. First, the connecting seat 1 is fixedly connected to the bottom end of the belt conveyor with bolts. After fixing, the bidirectional threaded rod 21 is manually rotated. The rotation of the bidirectional threaded rod 21 will cause the surface connecting blocks 22 to move closer or further apart. The moving closer or further apart of the connecting blocks 22 will simultaneously drive the two sets of connecting rods a23 to mesh and move closer or further apart. The meshing of the two sets of connecting rods a23 will simultaneously drive the connecting rod b24 to move synchronously. The moving closer or further apart of connecting rods a23 and connecting rod b24 will simultaneously drive the lower fixed seat 26 and the upper fixed seat 25 to move further apart. Because the extension... The retractable seat 27 is fixedly connected to the connecting seat 1, the upper fixed seat 25 is fixedly connected to the connecting seat 1, the lower fixed seat 26 is fixedly connected to the connecting frame 210, and the connecting frame 210 is fixedly connected to the telescopic leg 36. Therefore, when the upper fixed seat 25 and the lower fixed seat 26 move closer or further apart, the sliding block 28 will extend and retract on the inner wall of the telescopic seat 27 to achieve the effect of synchronously adjusting the length of the two sets of support legs. If it is necessary to adjust a set of support legs separately, simply rotate the fixing bolt 29 to disengage the fixing bolt 29 from the threaded groove of the connecting frame 210 and the sliding block 28, remove the limit on the sliding block 28, adjust the length of the sliding block 28 according to the length, and then fix the connecting frame 210 and the sliding block 28 with the fixing bolt 29 to complete the adjustment of a single support leg.

[0039] At the same time, as the sliding block 28 is adjusted downwards, it will cause the slider on the back of the support block 33 to slide in the triangular groove on the surface of the sliding plate 32. When the slider on the back of the support block 33 slides to both ends of the triangular groove, it will push the support block 33 to slide outwards on the surface of 37. Then, the length of the telescopic leg 36 is adjusted by the Enya wedge block 34 so that it contacts the ground, increasing the contact area and making the ground support more solid.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
