[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0023] Embodiment 1:

[0024] The utility model provides a front and rear protection structure for a bucket wheel machine, such as Figure 1-4 As shown, it includes a bucket wheel machine base 1: a front end protection structure 2 is installed at the front end of the bucket wheel machine base 1, and the front end protection structure 2 includes a semicircular plate 21 fixedly installed at the bottom of the front end of the bucket wheel machine base 1, a protective cloth 23 is sewn and connected to the bottom end of the semicircular plate 21, and a connecting strip 24 is sewn and connected to the edge of one end of the protective cloth 23, a positioning block 25 is installed inside the connecting strip 24 by screws, and the positioning block 25 is installed on the bucket wheel machine base 1 by screws, and a rear end barrier structure 3 is fixedly installed at the rear end of the bucket wheel machine base 1.

[0025] like Figure 2 As shown, vertical bars 22 are symmetrically welded on the top of the semicircular plate 21, and the vertical bars 22 are fixedly installed on the bucket wheel excavator base 1 by screws. The vertical bars 22 are used to fix the semicircular plate 21 and the bucket wheel excavator base 1, which changes the difficulty of fixing the semicircular plate 21. A discharge port 26 is opened at the bottom of one end surface of the semicircular plate 21. The discharge port 26 is used to discharge the items inside the protective cloth 23. A horizontal rod 27 is welded at one end of the semicircular plate 21 at the top position of the discharge port 26. An electric telescopic rod 28 is symmetrically embedded and installed at the bottom end of the horizontal rod 27, and the input end of the electric telescopic rod 28 is electrically connected to the output end of the external power supply. A blocking plate 29 is clamped and connected to the bottom end of the electric telescopic rod 28. The length and width of the blocking plate 29 are greater than the length and width of the discharge port 26. The electric telescopic rod 28 is used to drive the blocking plate 29 to move. The moved blocking plate 29 can block the discharge port 26 to prevent the external materials from being directly discharged along the discharge port 26.

[0026] like Figure 3 and Figure 4 As shown, the rear end blocking structure 3 includes a vertical plate 31 fixedly mounted on the rear end of the bucket wheel excavator base 1, the vertical plate 31 is used to block the conveyed material, an arc plate 32 is welded between the top ends of the two vertical plates 31, the arc plate 32 is used to block the material, a rotating plate 35 is rotatably connected between the two vertical plates 31, the rotating plate 35 reduces the impact force of the conveyed material and changes the direction of the material movement, a rotating rod 34 is connected to the rotating plate 35 through the internal clearance and the rotating rod 34 passes through the vertical plate 31, a guide plate 33 is welded between the bottom ends of the two vertical plates 31, the guide plate 33 is used to guide the material, which changes the difficulty of guiding the material, a fitting hole is opened in the vertical plate 31 at a position corresponding to one end of the rotating rod 34, the fitting hole is used to install the rotating rod 34, and can limit the rotating rod 34, the shape of the guide plate 33 is wavy, the guide plate 33 can change the material flow rate, thereby reducing the impact force between the material and the collection structure, and further increasing the safety factor of the device.

[0027] Working principle: During the actual use of the device, the user fixes the vertical bar 22 of the semicircular plate 21 and the bucket wheel machine base 1, then installs the positioning block 25 and the bucket wheel machine base 1, and then installs the connecting bar 24 and the positioning block 25. At this time, the connecting bar 24 drives the protective cloth 23 to be fixed with the positioning block 25, and the protective cloth 23 at the bottom of the positioning block 25 and the protective cloth 23 at the bottom of the semicircular plate 21 form an inclined shape. At this time, the protective cloth 23 collects the materials splashed at the front end of the bucket wheel machine base 1 to prevent the splashed materials from falling along the front end of the bucket wheel machine base 1 and causing the bucket wheel to fall. The problem of low safety factor at the front end of the machine base 1 occurs, reducing the diffusion of dust and particulate matter at the work site, and at the same time reducing accidental injuries that may be caused by material splashing, improving work safety, and slowly entering one end of the semicircular plate 21, and then the personnel start the electric telescopic rod 28, and the electric telescopic rod 28 drives the blocking plate 29 to move when it is running. After the blocking plate 29 moves, the discharge port 26 is opened, so that the material at one end of the semicircular plate 21 is discharged along the discharge port 26, so as to facilitate the collection of the splashed material, and prevent the protective cloth 23 from being subjected to the pressure of more materials and causing the protective cloth 23 to fall off;

[0028] Since the front end of the bucket wheel excavator base 1 transports the material to the rear end of the bucket wheel excavator base 1, the bucket wheel excavator base 1 transports the material. At this time, the bottom of the rear end of the bucket wheel excavator base 1 limits the material to the left and right through the vertical plate 31, and the material moves upward along the guide plate 33 when being transported at the rear end. The material after the upward displacement contacts the rotating plate 35, and the impact force of the material drives the rotating plate 35 to rotate. When the rotating plate 35 rotates, it rotates inside the vertical plate 31 through the rotating rod 34. At this time, part of the rising material passes through the obstruction of the arc plate 32 and falls onto the guide plate 33 again, which can limit the material moving at the rear end of the bucket wheel excavator base 1 and reduce its flow rate, thereby preventing the problem of splashing caused by excessive flow rate of the material at the rear end of the bucket wheel excavator base 1, further improving the safety of the bucket wheel excavator base 1 during use.

[0029] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
