[0001] The utility model relates to the technical field of mechanical equipment, in particular to an excavator bucket for a coal bunker. Background Art
[0002] In the coal industry, after collecting a large amount of coal, the coal is usually piled up in the coal bunker. When it needs to be transported, the coal is dug out, and an excavator is usually used to dig the coal out of the bunker. However, the existing excavator bucket is not suitable for excavating coal bunkers. For example, the Chinese utility model patent: CN215562893U, open-pit mining excavator bucket, includes: a bucket body, bucket teeth, and there is a gap between adjacent bucket teeth. When this type of bucket is actually used, the small coal or coal ash at the bottom cannot be cleaned up, and the coal may even be stuck between the bucket teeth. The manual cleaning environment is inefficient and the working environment is dangerous and harsh. In addition, the bucket teeth often bend or even break when encountering hard objects, which is not suitable for use in coal bunkers. Summary of the invention

[0004] The technical solution of the utility model includes a main board and side panels on both sides of the main board, wherein cutouts are formed at the inlets and outlets of the main board and the side panels, and a blade plate is fixed to the bottom of the main board, which covers the entire cutout edge of the main board between the side panels and extends outward.
[0005] By adopting the above technical solution, a whole blade plate is in the main excavation working part of the bucket, which can clean the coal slag at the bottom of the coal bunker and prevent coal from getting stuck in the bucket, thereby reducing manual participation and improving excavation efficiency. The plate-shaped blade plate is also not easy to bend and be damaged, which achieves efficient cleaning of the coal bunker while extending the service life of the bucket.
[0006] In a possible design, a thickened plate is fixedly provided at the edge of the cutout of the side plate, and the thickness of the thickened plate is greater than the thickness of the side plate.
[0007] With the above design, the thickened plate acts as the contact part with the coal and has stronger wear resistance.
[0008] In a possible design, a T-shaped rib plate is fixed between the blade plate and the top of the main board, and the two ends of the T-shaped rib plate are respectively welded to the inner side surfaces of the blade plate and the main board. The T-shaped rib plate is located in the middle position of the space between the side plates on both sides, and the cross-section of the T-shaped rib plate is T-shaped.
[0009] The above design is adopted to strengthen the overall structural strength of the bucket, prevent the blade plate from separating from the main board, improve the firmness of the blade plate, and the T-shaped rib plate provides a larger supporting area than ordinary sheet-like rib plates. The structural strength in the horizontal and longitudinal directions is further strengthened, effectively dispersing and resisting stress, being able to withstand greater loads, and significantly enhancing structural stability, which is very suitable for wider buckets.
[0010] In a possible design, the spacing between the side panels is greater than 1.5 meters.
[0011] The above design is equivalent to widening the bucket width, which is beneficial to improving the excavation capacity and is suitable for working conditions where the coal bunker only needs to be excavated and fed.
[0012] In a possible design, a connection seat is provided on the top of the main board, and the connection seat extends from the top surface of the main board toward the back side and is fixedly connected to the main board.
[0013] With the above design, the connecting seat is used to connect with the digging arm, and its extension to the back of the main board can strengthen the structural strength of the arc-shaped back of the main board and increase the weight that the digging bucket can bear.
[0014] In a possible design, a hook is also fixedly connected to the mainboard.
[0015] With the above design, the hook is used for the maintenance hanging position when the bucket is disassembled, which facilitates the maintenance work.
[0016] In a possible design, a reinforcing rib is fixedly provided at the corner between the thickened plate and the top of the main plate.
[0017] The above design makes the connection between the thickened plate and the main plate more secure, provides a more reliable and stable connection, and extends the service life of the structure.
[0018] In a possible design, a chamfer is provided at an outer side of the blade.
[0019] With the above design, the chamfer has the effect of cutting coal, the digging is smoother, and the cleaning work is more efficient and clean. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] like Figure 1-3 The bucket of a coal bunker excavator shown in the figure comprises a main board 1 and side boards 2 on both sides of the main board 1. The main board 1 and the side boards 2 form a digging opening at the inlet and outlet. A blade board 3 is fixed to the bottom of the main board 1. The blade board 3 covers the entire digging edge of the main board 1 between the side boards 2 on both sides and extends outward by 5 to 20 cm. The blade board 3 is in contact with the coal in the coal bunker through a whole piece of blade board 3. The blade board 3 can carry out digging and material carrying work along the bottom of the coal bunker, clean up the small volume of coal slag that is easy to remain in the coal bunker, and clean up more efficiently and cleanly.
[0025] A thickening plate 4 is fixedly arranged at the edge of the digging opening of the side plate 2, and the thickness of the thickening plate 4 is greater than that of the side plate 2, and the thickness can be twice that of the side plate 2. The thickening plate 4 will always be in contact with the coal during excavation, and increasing the thickness can enhance its wear resistance and bending strength.
[0026] The blade plate 3 and the thickened plate 4 can be fixed at the excavation by welding, which is simple to manufacture and has low cost.
[0027] A T-shaped rib plate 5 is fixed between the blade plate 3 and the top of the main board 1. The two ends of the T-shaped rib plate 5 are welded to the inner side surfaces of the blade plate 3 and the main board 1 respectively. The T-shaped rib plate 5 is located in the middle of the space between the side plates 2. The position of the T-shaped rib plate 5 is reasonably arranged, which can enhance the overall structural strength of the bucket. The cross section of the T-shaped rib plate 5 is T-shaped, which can provide a larger support area, and the structural strength in the horizontal and vertical directions is further enhanced.
[0028] The spacing between the side plates 2 on both sides is greater than 1.5 meters, which is equivalent to widening the bucket width and increasing the capacity of each excavation. It can be set to between 1.5 meters and 2.5 meters according to actual conditions. A bucket of this width can not only dig coal of the required weight, but also avoid the need to increase the specifications of the original excavator due to excessive weight.
[0029] A connection seat 6 is provided on the top of the main board 1, and the connection seat 6 extends from the top surface of the main board 1 to the back surface and is fixedly connected to the main board 1. The connection seat 6 is used to connect with the digging arm 9, and in order to adapt to the increase in digging capacity, the connection seat 6 is extended to the back of the main board 1, thereby reinforcing the structural strength of the curved back of the main board 1 and increasing the weight that the bucket can bear.
[0030] A hook 7 is also fixedly connected to the main board 1, and the bucket can be inspected and repaired through the hanger hook 7.
[0031] A reinforcing rib 8 is fixedly provided at the corner between the thickened plate 4 and the top of the main plate 1 , and the reinforcing rib 8 is used to strengthen the connection between the thickened plate 4 and the main plate 1 .
[0032] A chamfer 31 is provided at the outer side of the blade plate 3, and the thickness of the chamfer 31 gradually increases from the outside to the inside, so that it has the effect of cutting coal and is used to divide large pieces of coal into blocks to facilitate bucket feeding.
