The working environment of the excavator is very severe, and particularly, in the excavator working in a mine, the phenomenon that ores impact the bottom of a bucket rod often occurs in the process of loading and unloading the ores is often generated. In order to protect the bucket rod and reduce the impact of the ore on the bucket rod, the bottom of the bucket rod of the mine excavator is generally welded with an impact protection structure. The existing bucket rod impact protection structure is in a structural form as shown in fig. 1, wherein a reinforcing plate is welded at the bottom of a bucket rod, and a plurality of reinforcing ribs are welded on the reinforcing plate and are arranged along the length of the bucket rod. The welding mode of the reinforcing ribs adopts intermittent welding along the length direction.
The bucket rod impact protection structure has the following problems:
1. the ability to absorb the impact of the ore is weak. Among the above-mentioned dipper striking protection structure, the strengthening rib is the entity, and intensity is great. When the ore strikes the dipper, the strengthening rib transmits the impact energy of ore on the dipper bottom plate along its length direction, and the whole energy that the ore was strikeed still is used in the dipper bottom plate, can not transmit impact energy to the both sides of bottom plate and then transmit on the dipper both sides board, easily causes the too big and deformation of impact that the dipper bottom bore, and then arouses the dipper bottom plate and the fracture of dipper both sides curb plate welding department and inefficacy.
2. The rigidity of the bucket rod impact protection structure is overlarge. Among the above-mentioned dipper striking protection architecture, the strengthening rib is arranged and is in large quantity along dipper length direction, causes the dipper to be serious along length direction rigidity sudden change, and the dipper easily breaks at striking protection architecture tip.
Disclosure of Invention
The invention aims to solve the technical problem that the impact resistance of a bucket rod of the existing excavator cannot be improved well by an impact protection structure on the bucket rod, and provides the excavator bucket rod capable of effectively improving the impact resistance of the bucket rod.
The technical scheme for realizing the purpose of the invention is as follows: the excavator bucket rod is mainly of a box-type structure formed by welding a top plate, a bottom plate and two side plates, and the distance between the outer side surfaces of the two side plates is smaller than the width of the bottom plate; the novel bucket is characterized in that a plurality of rib plates are welded on the bottom surface of the front portion of the bottom plate, the rib plates are arranged at intervals in the length direction of the bucket rod, the length direction of the rib plates is perpendicular to the length direction of the bucket rod, and two ends of each rib plate protrude to the outer sides of projections of the two side plates on the bottom plate. In the invention, when ores impact on the rib plates, impact force is transmitted to two sides along the length direction of the rib plates and then transmitted to two side plates of the bucket rod through two side edges of the bottom plate of the bucket rod, so that the impact force on the bottom plate of the bucket rod is reduced, and the bucket rod is effectively protected; simultaneously, stress acting on a weld joint when the bucket rod deforms is reduced, and the risk of cracking of the bucket rod is reduced.
In the excavator bucket rod, the rib plate is of a hollow structure. The rib plate is of a groove-shaped structure, and the notch of the rib plate is attached to the bottom plate of the bucket rod relatively. The rib plates can be made of channel steel or formed by bending or welding steel plates into a groove shape, furthermore, two ends of the groove-shaped rib plates are closed, and the rib plates are only welded with the bottom plate at two ends. The hollow rib plate can well absorb the impact energy of ore impacting the bucket rod, and the risk that the bucket rod is cracked due to impact deformation of the bottom plate of the bucket rod is reduced.
Further, in the excavator bucket rod, the top surface of the rib plate is attached to the bottom plate, one or two grooves are formed in the top surface of the rib plate, and the grooves vertically penetrate through the top surface of the rib plate in the width direction of the rib plate. When the ore impacts the rib plates, the rib plates deform at the positions of the grooves to absorb the impact energy of the ore. The grooves on two adjacent rib plates are staggered in the length direction of the rib plates, so that the energy impacting on each part of the bucket rod is absorbed.
Compared with the prior art, the invention has the following advantages:
1. the rib plate is directly welded on the bottom plate, and compared with the original structure, the rib plate does not need to be welded, so that the weight is reduced, and the cost is reduced to a certain extent.
2. According to the invention, the rib plates can transmit the impact force of the ore to the two sides of the bucket rod, so that the impact force of the middle part of the bottom plate of the bucket rod is effectively reduced, the impact energy of the ore is effectively absorbed, and the damage to the bucket rod is reduced.
3. In the invention, each rib plate is small and independent, and is easy to replace when in failure.
4. According to the invention, the length direction of the rib plate is vertical to the length direction of the bucket rod, so that the influence on the rigidity change of the bucket rod in the length direction is small, and the risk of cracking of the bucket rod caused by rigidity mutation can be effectively reduced.

Detailed Description
The following description of the embodiments refers to the accompanying drawings.
In the embodiment, the excavator bucket rod structure is shown in fig. 1, the bucket rod mainly has a box-shaped structure formed by welding a top plate, a bottom plate 1 and two side plates 2, the two side plates 2 are vertically welded on the top surface of the bottom plate 1, that is, the distance between the outer side surfaces of the two side plates 2 is smaller than the width of the bottom plate 1. A plurality of rib plates 5 are welded on the bottom surface of the front portion of the bottom plate 1, the rib plates 5 are arranged at intervals in the length direction of the bucket rod, the length direction of the rib plates 5 is perpendicular to the length direction of the bucket rod, two ends of the rib plates 5 protrude to the outer sides of projections of the two side plates 2 on the bottom plate, namely, the projections of the two side plates 2 on the bottom plate are intersected with the projections of the rib plates 5 on the bottom plate 2. . The impact force with the ore that this kind of structure can be better transmits to the both sides board of dipper on, reduces the stress that acts on the weld when the dipper warp simultaneously, reduces the risk of dipper fracture.
The top surface of the rib plate 5 is attached to the bottom plate 2, the structure of the rib plate is shown in figure 3, the rib plate is of a hollow structure, the rib plate is of a groove-shaped structure, and the notch of the rib plate is attached to the bottom plate of the bucket rod relatively.
