Description

Technical Field

[0001] The utility model relates to the technical field of excavators, in particular to an excavator shovel plate used for excavating frozen coal. Background Art

[0002] In the mining industry, the mining method has gradually changed to excavators replacing explosives to directly mine materials. The traditional bucket shape has adapted to many working conditions, but it is mainly used in the excavation and loading of loose materials. Secondly, the bottom and side anti-wear structures of traditional buckets are welded together by multiple plates. Many of the welds are prone to cracking and wear due to direct contact and collision with the materials, causing the reliability of the anti-wear structure to decrease. When excavating harder objects, the hardness of the excavated objects can easily cause the vibration of the excavator bucket to increase, increasing the probability of damage to the excavator bucket.

[0003] When working in coal mines in winter, frozen coal is an unavoidable topic. Frozen coal refers to the phenomenon of coal freezing due to low temperatures. In winter, the temperature drops sharply, and coal is easily affected by low temperatures during transportation and storage, which manifests as agglomeration, solidification and freezing. Frozen coal is transported to the port by train cars. After passing through the dumper, sometimes 2 / 3 of the coal in the car cannot be unloaded. Common unloading methods include manual unloading with pickaxes and shovels, and unloading with an excavator bucket. When the excavator bucket excavates frozen coal, the frozen coal is hard, which causes large vibrations during operation of the excavator bucket, which can easily cause damage to the bucket.

[0004] In view of the above-mentioned problem that when the excavator bucket excavates frozen coal, the frozen coal is hard, resulting in large vibrations of the excavator bucket during operation, which easily causes damage to the bucket, an excavator shovel plate for excavating frozen coal is needed. Summary of the invention

[0005] Aiming at the problem that when excavating frozen coal, the excavator bucket vibrates greatly during operation and is easily damaged due to the hardness of the frozen coal, the utility model proposes an excavator shovel plate for excavating frozen coal.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is an excavator shovel plate for frozen coal excavation, including a connecting piece connected to the excavator arm, a clamping plate is fixed at the bottom of the connecting piece, a shovel plate is fixed at the bottom of the clamping plate, and high-strength shovel teeth are installed at the bottom of the shovel plate. When in use, the excavator shovel plate is connected to the excavator through the connecting piece, and then the frozen coal is excavated and crushed by the high-strength shovel teeth, and the frozen coal is moved onto the steel grille and transported through the funnel under the steel grille. Compared with the traditional excavator bucket, the excavator shovel plate is more suitable for frozen coal excavation work, can excavate and crush frozen coal, and at the same time, the high-strength shovel teeth are used to increase the service life of the shovel plate, improve the use effect, and have good practicality.

[0007] Furthermore, two reinforcing ribs 1 are fixed between the connecting piece and the clamping plate, and the two reinforcing ribs 1 are symmetrically distributed on both sides of the clamping plate. The reinforcing ribs 1 can improve the stability between the connecting piece and the clamping plate.

[0008] Furthermore, a mounting groove is provided at the bottom of the clamping plate, and the upper part of the shovel plate is inserted into the mounting groove and fixed to the clamping plate. The mounting and fixing method of the mounting groove facilitates the replacement of the shovel plate at a later time, and the use effect is better.

[0009] Furthermore, four reinforcing ribs 2 are fixed between the clamping plate and the shovel plate, two reinforcing ribs 2 are fixed on one side of the shovel plate, and the two reinforcing ribs 2 are distributed in an eight-shaped shape. The reinforcing ribs 2 can enhance the stability between the clamping plate and the shovel plate.

[0010] Furthermore, a high-strength base is fixed to the bottom of the shovel plate, and the high-strength shovel teeth are installed on the high-strength base. The high-strength base can reduce the contact area of ​​the shovel plate with the frozen coal, thereby increasing the service life of the shovel plate and facilitating the replacement of the high-strength shovel teeth.

[0011] Furthermore, the high-strength base and high-strength shovel teeth are made of manganese steel.

[0012] The beneficial effects of the utility model are:

[0013] When using the excavator shovel for frozen coal excavation, first remove the excavator bucket, then use the connecting piece to connect the excavator shovel for frozen coal excavation to the excavator, increase the wear resistance and make the rigidity stronger through the high-strength base and high-strength shovel teeth at the bottom of the shovel, excavate and crush the frozen coal through the high-strength shovel teeth, then push the frozen coal onto the ground steel grid, and recover it onto the belt conveyor through the funnel under the steel grid to complete the frozen coal transportation work, with good overall use effect.
