DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-5 In this embodiment, a groove forming machine with adjustable slope gradient includes a forming machine bucket structure consisting of a bucket bottom plate 1, a bucket side plate 2, a bucket top plate connecting seat 4, two leveling plates 3, an excavating head 5, an excavator mechanical arm 8 and a bucket rear baffle 18.

[0029] The adjustment component in this embodiment includes a movable groove 6 opened on the left and right sides of the bottom of the bucket top plate connecting seat 4, a through-hole 7 opened on the left and right sides of the top of the bucket top plate connecting seat 4 and connected to the movable groove 6, a guide groove 10 opened on the front surface of the bucket top plate connecting seat 4 and a hydraulic push rod 9 fixedly installed on the front surface of the bucket top plate connecting seat 4, a movable seat 11 located outside the bucket top plate connecting seat 4 and slidably connected to the guide groove 10 is fixedly installed at the push rod of the hydraulic push rod 9, and a rotating rod 12 passing through the through-hole 7 is movably installed on the left and right sides of the movable seat 11, and an extension plate 13 slidably connected to the movable groove 6 is movably installed on the end of the rotating rod 12 away from the movable seat 11, and the two extension plates 13 are movably connected to the two bucket side plates 2 respectively.

[0030] In this embodiment, the lower surface of the extension plate 13 is aligned with the lower surface of the bucket top plate connecting seat 4, and the extension plate 13 and the movable groove 6 are not separated from each other.

[0031] It should be noted that a number of digging heads 5 distributed at equal distances are fixedly installed on the front surface of the bucket bottom plate 1, and bucket side plates 2 are movably installed on the left and right sides of the bucket bottom plate 1. A bucket top plate connecting seat 4 is fitted between the two bucket side plates 2. At the same time, a bucket rear baffle 18 is fixedly installed between the bucket top plate connecting seat 4 and the bucket bottom plate 1. A leveling plate 3 is movably installed on the top of the bucket side plate 2, and the top of the bucket top plate connecting seat 4 is fixedly connected to the excavator mechanical arm 8 through a connecting shaft.

[0032] The bucket bottom plate 1 and the bucket side plate 2 as well as the bucket side plate 2 and the leveling plate 3 are all hinged by hinges.

[0033] The sealing member in this embodiment includes a movable groove 2 15 opened on the left and right sides of the bucket rear baffle 18 and a plurality of mounting grooves 14 opened on the left and right sides of the bucket rear baffle 18 and connected to the movable groove 2 15. An elastic telescopic rod 16 is fixedly installed in the mounting groove 14, and a sealing plate 17 located in the movable groove 2 15 is fixedly installed on the outer side of the elastic telescopic rod 16. An elastic rubber block 19 in contact with the bucket side plate 2 is fixedly installed on the outer side of the sealing plate 17.

[0034] It should be noted that the movable groove 2 15 and the left and right sides of the bucket rear baffle 18 are of equal width, the multiple sealing plates 17 fit together, and the length of the sealing plates 17 decreases from top to bottom while the length of the installation groove 14 decreases from top to bottom.

[0035] The elastic telescopic rod 16 consists of a telescopic spring and a telescopic rod. The telescopic rod consists of an outer tube and an inner rod. The inner tube is slidably connected to the inner tube and extends to the outside of the outer tube. The ends of the outer tube and the inner rod that are away from each other are fixedly connected to the inner ends of the telescopic spring, and the outer ends of the telescopic spring are fixedly connected to the bucket rear baffle 18 and the sealing plate 17, respectively. The outer tube and the inner rod are not separated from each other.

[0036] The leveling structure in this embodiment includes a mounting hole 20 opened inside the bucket top plate connecting seat 4, a servo motor 21 is fixedly installed in the mounting hole 20, a movable seat 22 is fixedly installed in the mounting hole 20, a threaded rod 31 movably connected to the movable seat 22 is fixedly installed at the output shaft of the servo motor 21 through a coupling, the external thread of the threaded rod 31 is connected to the threaded movable seat 23, and movable rods 24 movably connected to the leveling plate 3 are movably installed on both sides of the threaded movable seat 23.

[0037] In this embodiment, the threaded rod 31 is rotationally connected to the movable seat 22, and the threaded rod 31 rotates in a circle. The movable rod 24 is connected to the flat plate 3 and the threaded movable seat 23 in a rotational manner.

[0038] It should be noted that the adjustment and positioning mechanism includes two positioning rods 27 fixedly installed in the mounting hole 20, positioning through-holes 25 opened on the left and right sides of the threaded movable seat 23 and passed through by the positioning rods 27, and connecting grooves 26 opened on the left and right sides of the threaded movable seat 23 and connected to the positioning through-holes 25. The opposite surfaces of the two positioning rods 27 are provided with a number of tooth grooves 30, and a spring 28 is fixedly installed in the connecting groove 26. The outer side of the spring 28 is fixedly installed with an electromagnet tooth block 29 that meshes with the tooth groove 30. The number of tooth grooves 30 is not less than thirty, and the tooth grooves 30 are distributed at equal distances vertically. The spring 28 is a plastic spring. When the spring 28 is in a contracted state, the electromagnet tooth block 29 does not contact the positioning rod 27. When the spring 28 is in an extended state, the electromagnet tooth block 29 is located in the tooth groove 30. The electromagnet tooth block 29 is a tooth block provided on the outer side of the electromagnet.

[0039] It can be understood that when the threaded movable seat 23 is moved up and down for adjustment, the electromagnetic tooth block 29 provided therewith is energized to generate magnetism and is simultaneously adsorbed and fixed in the tooth groove 30 on the positioning rod 27, thereby achieving locking and fixing of the threaded movable seat 23 after movement, ensuring the stability of the leveling plate 3 after adjustment. At the same time, when the leveling plate 3 needs to be adjusted, the electromagnetic tooth block 29 is de-energized and the elastic resetting action of the spring 28 pulls the electromagnetic tooth block 29 back to its original position and separates it from the tooth groove 30, thereby facilitating the movement and adjustment of the threaded movable seat 23.

[0040] The positioning rod 27 is made of iron material and can be adsorbed and fixed by the electromagnet tooth block 29 .

[0041] The working principle of the above embodiment is:

[0042] The hydraulic push rod 9 is provided, which facilitates the excavation of trenches with different slope gradients. When the hydraulic push rod 9 works, it pushes the moving seat 11 to move stably in the guide groove 10. At the same time, the movement of the moving seat 11 drives the rotating rod 12 to rotate, so that the rotating rod 12 pushes the two extension plates 13 to move stably in the moving groove 6 while rotating, so that the movement of the extension plate 13 and the rotation of the bucket side plate 2 simultaneously push the two bucket side plates 2 to rotate and spread on the bucket bottom plate 1, so as to achieve the purpose of changing the inclination angle of the bucket side plate 2 and ensure the change of the excavation slope of the trench side during excavation;

[0043] At the same time, when the bucket side plate 2 moves, as the bucket side plate 2 and the bucket rear baffle 18 separate, under the elastic expansion and contraction action of the elastic expansion rod 16, it is ensured that when the bucket side plate 2 moves, the elastic expansion rod 16 is synchronously extended to push the sealing plate 17 to move in the second moving groove 15, so that the sealing plates 17 are in contact with each other and the elastic rubber block 19 is always kept in contact with the bucket side plate 2, thereby ensuring that after the inclination angle of the bucket side plate 2 is adjusted, the bucket bottom plate 1, the bucket side plate 2, the bucket rear baffle 18, the sealing plate 17, the elastic rubber block 19, the bucket top plate connecting seat 4 and the extension plate 13 are always combined and sealed into a bucket shape, which is convenient for trenching;

[0044] In addition, by setting up the servo motor 21, it is ensured that after the inclination angle adjustment of the bucket side plate 2 is completed, the servo motor 21 drives the threaded rod 31 to rotate on the movable seat 22. At the same time, the threaded connection between the threaded movable seat 23 and the threaded rod 31 and the upper and lower limit effects of the mounting hole 20 on the threaded movable seat 23 are utilized to ensure that the threaded rod 31 rotates while driving the threaded movable seat 23 to move and driving the movable rod 24 to rotate on the leveling plate 3, thereby driving the leveling plate 3 to rotate and adjust the level, thereby ensuring that the leveling plate 3 can be adjusted synchronously when the bucket side plate 2 is adjusted, thereby facilitating the leveling of the top two sides of the trench when digging the trench.

[0045] The electrical components mentioned in this article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device that controls a computer, etc., and the existing public power connection technology is not described in detail in this article.
