[0029] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] Example 1:

[0031] like Figure 1 and Figure 2 As shown in the figure, the one-time molded excavator bucket for digging ditches provided in this embodiment includes a ditch bottom forming part 1. The top of both sides of the ditch bottom forming part 1 is provided with a ditch wall forming part 2. The end of the ditch wall forming part 2 away from the ditch bottom forming part 1 is provided with a platform forming part 3. A top plate 4 is provided between the two ditch wall forming parts 2. The top plate 4, the ditch wall forming part 2 and the rear side of the ditch bottom forming part 1 are connected to a back plate 5. The top plate 4, the back plate 5, the ditch wall forming part 2 and the ditch bottom forming part 1 form an isosceles trapezoidal bucket cavity. An exhaust hole 6 is provided on the back plate 5. A soil cutting part 7 is provided between the top plate 4 and the back plate 5. The top, bottom and back of the soil cutting part 7 are fixedly connected to the top plate 4, the ditch bottom forming part 1 and the back plate 5 respectively. The soil cutting part 7 divides the bucket cavity into two sub-bucket cavities.

[0032] The bottom forming part 1, the wall forming part 2, and the platform forming part 3 are adapted to the bottom, wall, and platform of the excavated ditch. During the ditch excavation process, the bottom, wall, and platform can be formed in one go, which greatly improves the ditch forming effect and increases the efficiency of ditch excavation.

[0033] The vent 6 reduces resistance during ditch excavation, making it easier for soil to enter the bucket cavity. The soil cutting section 7 allows for better soil cutting during ditch excavation, reducing resistance. Furthermore, the soil cutting section 7 improves the overall rigidity and strength of the bucket, extending its service life and enhancing the ditch formation effect.

[0034] In a relatively specific embodiment, the trench bottom forming part 1, the trench wall forming part 2, and the platform forming part 3 are all steel plates, and the soil cutting part 7 is a thin steel plate.

[0035] The top plate 4 includes an upper plate 4.1 and a lower plate 4.2 that are spaced apart vertically. Long horizontal I-beams 4.3 are provided at both ends between the upper plate 4.1 and the lower plate 4.2. The top of the back plate 5 and the top of the soil cutting part 7 are fixed to the lower plate 4.2. The two ends of the upper plate 4.1, the lower plate 4.2 and the long horizontal I-beams 4.3 are fixed to the trench wall forming part 2.

[0036] This design of the top plate 4 ensures it has sufficient strength. A connecting member 8 for connecting the excavator boom is fixedly installed on the top of the upper plate 4.1. During the excavation of the ditch by the bucket, the excavator boom applies force directly to the top plate 4 through the connecting member 8. Consequently, the top plate 4 has sufficient rigidity and strength, which improves the excavation effect of the ditch.

[0037] In a relatively specific embodiment, the connecting member 8 includes two side plates symmetrically distributed in the width direction. The bottom of the side plates is fixedly connected to the top of the upper plate 4.1, and the back of the side plates extends downward into the range of the back plate 5. The portion of the side plates extending into the range of the back plate 5 is fixedly connected to the back plate 5. A pin for connecting the excavator boom is installed between the two side plates. A diagonal brace is provided between the side of the side plate and the upper plate 4.1.

[0038] This design ensures that the connecting member 8 has sufficient strength and that the connecting member 8, the top plate 4, and the back plate 5 together form a rigid and strong whole.

[0039] The long horizontal I-beam 4.3 has oblique I-beams 9 fixedly connected to both the front and rear sides of its top. The platform forming part 3 has short horizontal I-beams 10 on both the front and rear sides of its top. The inner end of the short horizontal I-beam 10 is fixed to the outer end of its corresponding oblique I-beam 9. The oblique I-beam 9 is fixedly connected to the trench wall forming part 2. The upper plate 4.1 is fixedly connected to the oblique I-beam 9.

[0040] By connecting the inclined H-beam 9 and the short transverse H-beam 10 with the long transverse H-beam 4.3 to form a whole, the overall rigidity and strength of the bucket can be further improved.

[0041] Example 2:

[0042] like Figures 3 to 8 As shown in the second embodiment, a baffle 11 capable of moving back and forth is provided inside the sub-bucket cavity, and a cutting frame 12 capable of extending out of the sub-bucket cavity is provided at the front end of the cavity body. The four sides of the baffle 11 and the cutting frame 12 are all configured to fit against the four inner walls of the sub-bucket cavity. A driving structure is provided inside the sub-bucket cavity to drive the cutting frame 12 to reciprocate back and forth when the baffle 11 moves.

[0043] After setting up the baffle 11 and the cutting frame 12, when the ditch is being excavated, as the soil enters the sub-bucket cavity, the baffle 11 inside the sub-bucket cavity is pushed backward under the pressure of the soil. At this time, the drive structure is activated, causing the cutting frame 12 to continuously extend or retract inside the sub-bucket cavity. The reciprocating motion of the cutting frame 12 is used to cut the soil, ensuring smoother ditch excavation.

[0044] In a relatively specific embodiment, the drive structure includes a rack 13, a gear 14, an eccentric rotating rod 15, a drive plate 16, and a drive frame 17. The front end of the rack 13 is fixedly connected to the rear side of the baffle 11. The gear 14 is rotatably installed in the sub-bucket cavity and meshes with the bottom of the rack 13. One end of the eccentric rotating rod 15 is fixed to the gear 14. A strip-shaped groove is provided on the drive plate 16 and is sleeved on the eccentric rotating rod 15. The rear end of the drive plate 16 extends out of the sub-bucket cavity and is fixedly connected to the drive frame 17. The front end of the drive frame 17 is fixedly connected to a connecting plate 18 that extends into the sub-bucket cavity and is fixedly connected to the cutting frame 12.

[0045] During the backward displacement of the baffle 11, the rack 13 is displaced. At this time, the rack 13 drives the gear 14 to rotate, the gear 14 drives the eccentric rod 15 to rotate, and the eccentric rod 15 drives the drive plate 16 to move back to the reset position during the rotation. The drive plate 16 drives the drive frame 17 to move back to the reset position, and the drive frame 17 drives the cutting frame 12 to move back to the reset position through the connecting plate 18 to cut the soil.

[0046] During the process of dumping soil from the bucket, the baffle 11 will move forward. At this time, the cutting frame 12 will also move back and forth. In this way, the movement of the soil in the bucket cavity can be improved by using the movement of the cutting frame 12, thereby improving the dumping effect.

[0047] The baffle 11 is provided with an auxiliary air hole 19, and the exhaust hole 6 is located at the bottom of the back plate 5. With this configuration, the auxiliary air hole 19 can reduce resistance during the digging process, and the soil falling from the auxiliary air hole 19 into the space between the baffle 11 and the back plate 5 can fall out of the bucket cavity through the exhaust hole 6 when the bucket leaves the ditch with the back plate 5 facing downwards.

[0048] The tail end of the rack 13 passes through the back plate 5 and is fixedly connected to a reinforcing plate 20. Specifically, in a relatively specific embodiment, each sub-bucket cavity has two racks 13 and gears 14, which are distributed on both sides of the sub-bucket cavity in the width direction. This arrangement allows the two racks 13 to support the baffle 11 simultaneously, improving the stability and balance of the baffle 11. The eccentric rotating rod 15 is U-shaped, and both ends of the eccentric rotating rod 15 are fixedly connected to the center of the two gears 14. The drive plate 16 is L-shaped, with a strip groove on the vertical part of the drive plate 16. The rear end of the longitudinal part of the drive plate 16 passes through the back plate 5 and is fixedly connected to the drive frame 17.

[0049] The cutting frame 12 has grooves 21 on all four sides, and the grooves 21 are slidably fitted onto the outside of the connecting plate 18. The cutting frame 12 can slide smoothly in the sub-cavity through the grooves 21, and the connecting plate 18 can also slide smoothly in the sub-cavity through the grooves 21.

[0050] In a relatively specific embodiment, the four sides of the baffle 11 extend rearward, so that the four sides of the baffle 11 have sufficient contact area with the four inner walls of the sub-cavity, thereby improving the stability and balance of the baffle 11.

[0051] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
