Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to an excavator bucket assembly for building construction. Background Art

[0002] An excavator, also known as an excavator or a backhoe, is an earth-moving machine that uses a bucket to dig materials above or below the bearing surface and loads them into a transport vehicle or unloads them to a stockpile. The materials excavated by the excavator are mainly soil, coal, silt, and pre-loosened soil and rock. From the development of engineering machinery in recent years, the development of excavators has been relatively fast, and excavators have become one of the most important engineering machinery in engineering construction. The three most important parameters of an excavator are operating weight (mass), engine power, and bucket capacity. A bucket excavator is a type of excavator. Its main device, the bucket, is a working device on the hook machine. It is a bucket-shaped component that directly contacts the soil. The oil cylinder uses high-pressure oil as a medium and connecting rods as auxiliary mechanisms to drive the bucket for excavation. It is divided into a front shovel bucket excavator and a backhoe bucket excavator.

[0003] For example, it is now found that a typical excavator bucket assembly in the prior art is such as authorization number CN103114621B, an excavation bucket. In view of the shortcoming that the reinforcement plate on the side cover plate of the existing excavation bucket can only strengthen the rigidity of the side cover plate but cannot strengthen the strength of the entire bucket, an excavation bucket is provided, which includes a bottom plate and a groove plate, the groove plate is welded to the top of the bottom plate, a hinged ear plate is welded at the middle position of the bottom plate and the groove plate, a side cover plate is welded on the left and right sides of the bottom plate and the groove plate, a side blade plate is welded on the side cover plate at the opening of the bucket, and at least one strip-shaped reinforcement plate is welded on each side cover plate, the lower end of the reinforcement plate is connected to the side blade plate, and the upper end is inclined toward the top of the bottom plate and extends to the upper edge of the side cover plate. In the present invention, the reinforcing plate arranged in this way can effectively strengthen the rigidity of the side sealing plate to prevent it from being deformed when it is hit. At the same time, during operation, after the load on the hinged ear plate is transferred to the side sealing plate through the top of the bottom plate and the groove plate, the reinforcing plate is conducive to gathering the load on the side edge plate, thereby improving the strength of the entire bucket.

[0004] For another example, it is now found that the excavator bucket assembly in the prior art is typically such as authorization number CN105133678B, a double-bucket excavator. The technical problem of low excavation efficiency in the prior art is solved. It includes a fixed seat and a movable seat rotatably connected to the fixed seat, and the movable seat is provided with a first bucket assembly and a second bucket assembly facing in opposite directions, the first bucket assembly includes a first digging arm and a first bucket rotatably connected to the first digging arm, the second bucket assembly includes a second digging arm and a second bucket rotatably connected to the second digging arm, and the second bucket is evenly provided with a plurality of buckets along the circumference of the second bucket, and the second digging arm is provided with a bucket driver that can drive the second bucket to rotate circumferentially. The present invention can realize excavation of hard soil and soft soil, and can realize continuous operation during excavation, greatly improving the excavation efficiency of the excavator.

[0005] For another example, it is now found that the excavator bucket assembly in the prior art is typically such as authorization number CN104631528B, which involves an excavator bucket. In order to solve the shortcomings of the existing bucket with heavy weight and large excavation resistance, the present invention discloses an excavator bucket, wherein the front edge of the inner plate is provided with a main blade plate, and the left and right side plates are respectively provided with a left guard plate and a right guard plate extending from the front end of the bottom to the left and right ends of the arc connection part of the bucket bottom, and the transverse reinforcing strips are welded at intervals on the outside of the arc connection part, and the outside of the front part of the bucket bottom has a longitudinal reinforcing plate welded at intervals, the rear end of the reinforcing plate is welded to the reinforcing strips, the front end of the reinforcing plate is welded to the main blade plate, and there is a longitudinal wear-resistant plate between adjacent reinforcing plates and between the reinforcing plate and the left and right guard plates. Compared with the prior art, the beneficial effects of the present invention are strong structural rigidity, more reasonable structural design, reduced excavation resistance, less material, and cost saving.

[0006] For another example, it is now found that the excavator bucket assembly in the prior art is typically such as authorization number CN104563175B. The present invention relates to an excavator bucket. In order to solve the efficiency conflict problem of the existing excavator bucket when digging and leveling the ground, the present invention discloses a bucket including a left side plate, a right side plate, and a bucket bottom. The front part of the bucket bottom is a flat plate, the rear part is a back plate, and the middle part is an arc connecting part. The front edge of the flat plate is provided with a main blade plate, and at least one longitudinal strip-shaped leveling rib is welded on the bottom surface of the bucket bottom. The front end of the leveling rib is butted with the main blade plate, and the rear end is overlapped on the arc connecting part of the bucket bottom. The bottom surface edge of the leveling rib is a flat straight line, and the top surface shape of the leveling rib matches the bottom shape of the bucket bottom and fits with the bucket bottom. The leveling rib of the present invention increases the straight line surface in the left and right directions and improves the leveling efficiency; the leveling rib plate in the excavation direction protrudes downward, has a resistance effect on the soil, has a guiding effect on the bucket during excavation, and has less resistance to excavation, and can be used as a wear-resistant plate, so the bucket is more wear-resistant.

[0007] When the existing excavator bucket assembly is unloading soil, the soil is easy to stick to the inner wall of the bucket, which will lead to incomplete unloading and manual cleaning is also troublesome. When the amount of soil adhered to the bucket is large, it will not only reduce the effective bucket capacity of the bucket, but also increase the working load of the excavator, thereby extending the operating cycle time of the excavator, and then reducing the construction efficiency. In view of the above problems, it is necessary to improve the existing equipment. Summary of the invention

[0008] The object of the present invention is to provide an excavator bucket assembly for construction, so as to solve the problem proposed in the above-mentioned background technology that when unloading soil, the existing excavator bucket assembly is prone to sticking to the inner wall of the bucket, which will result in incomplete unloading and troublesome manual cleaning. When the amount of soil adhered to the bucket is large, it will not only reduce the effective bucket capacity of the bucket, but also increase the working load of the excavator, thereby extending the operating cycle time of the excavator and reducing the construction efficiency.

[0009] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an excavator bucket assembly for construction, comprising a bucket arm, a support plate is rotatably connected to the outer side of the bottom of the bucket arm, a bucket is fixed to the outer side of the support plate, shovel teeth are fixed to the end of the bucket, an intermittent oil pumping mechanism is fixed to the bucket, a connecting channel is provided in the bucket, a knocking groove is provided on an inner wall of the connecting channel, an automatic knocking mechanism is fixed in the knocking groove, the automatic knocking mechanism comprises a support block, one side of the support block is connected to a movable block through a third compression spring, the movable block extends into the connecting channel, and a knocking block is fixed to one side of the movable block.

[0011] Working principle: The bucket arm is installed on the boom of the excavator, and the bucket arm is rotatably connected to the boom. The bucket hydraulic cylinder, hydraulic rod, first connecting rod and second connecting rod are used together to control the movement of the bucket so as to realize digging and unloading. The shovel teeth can increase the grip. Hydraulic oil is stored in the second hydraulic cylinder. When the bucket is used to unload soil, the bucket rotates relative to the bucket arm, the first hydraulic cylinder moves relative to the arc rod, and the first piston block moves with the support sleeve and the pulling block. The first piston block slides in the first hydraulic cylinder, and the second piston block slides in the second hydraulic cylinder. After the card block is aligned with the card slot, it will automatically bounce into the card slot under the action of the second compression spring, and the first hydraulic cylinder continues to move relative to the arc rod. During movement, the first compression spring is compressed. When the first compression spring is compressed to the bottom, when the first hydraulic cylinder continues to move relative to the arc rod, the pulling block pulls the supporting sleeve and the first piston block, causing the blocking block to leave the slot. After the blocking block leaves the slot, the first compression spring automatically resets. The slots are evenly spaced on the two inner walls of the first hydraulic cylinder. The first piston block moves intermittently in the first hydraulic cylinder, thereby intermittently extracting the hydraulic oil in the second hydraulic cylinder. The movable block moves back and forth under the support of the oil pressure and the third compression spring. The knocking block moves back and forth and repeatedly knocks the bucket, making the unloading operation more thorough and clean. When digging, the knocking block will also repeatedly knock the bucket to prevent the soil from sticking to the inner wall of the bucket.

[0013] By adopting the above technical solution, the first connecting rod plays a role of connecting the hydraulic rod and the bucket arm, and the second connecting rod plays a role of connecting the hydraulic rod and the support plate.

[0014] Preferably, the intermittent oil pumping mechanism includes a first hydraulic cylinder, and the first hydraulic cylinder is fixed to the head end of the bucket, and the second hydraulic cylinder is connected to the first hydraulic cylinder through a connecting channel.

[0015] By adopting the above technical solution, the connecting channel can connect the first hydraulic cylinder with the second hydraulic cylinder.

[0016] Preferably, the two inner walls of the first hydraulic cylinder are symmetrically provided with card slots, and the card slots are evenly spaced on the two inner walls of the first hydraulic cylinder.

[0017] By adopting the above technical solution, the first hydraulic cylinder can intermittently pump out pressure oil through the setting of the card slot.

[0018] Preferably, an arc rod is fixed on one side of the boom, and the arc rod passes through one end of the first hydraulic cylinder and is connected to the pulling block, one side of the pulling block is connected to the supporting sleeve through a first compression spring, and the first compression spring is wrapped around the outside of the arc rod.

[0019] By adopting the above technical solution, the first compression spring plays a supporting role on the pulling block.

[0020] Preferably, the arc-shaped rod passes through the supporting sleeve, and the pulling block is slidably connected to the inner side of the supporting sleeve.

[0021] By adopting the above technical solution, the pulling block can slide in the supporting sleeve.

[0022] Preferably, a first piston block is fixed to one side of the support sleeve, and the first piston block is slidably connected in the first hydraulic cylinder.

[0023] By adopting the above technical solution, the movement of the support sleeve can drive the first piston block to move, so as to facilitate the extraction of hydraulic oil into the first hydraulic cylinder or the pressing out of the hydraulic oil in the first hydraulic cylinder.

[0026] Preferably, the knocking blocks are slidably connected in the knocking grooves, and the knocking blocks are evenly spaced in the connecting channel.

[0027] By adopting the above technical solution, during the process of digging and unloading soil, the knocking block can move back and forth and knock the bucket, which can effectively prevent soil from sticking to the bucket.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. The bucket assembly of the excavator for construction can achieve the purpose of digging and unloading soil through the coordinated use of the bucket arm, bucket hydraulic cylinder, hydraulic rod, first connecting rod, second connecting rod, bucket and shovel teeth. The bucket arm is installed on the boom of the excavator, and the bucket arm is rotatably connected to the boom. The bucket hydraulic cylinder, hydraulic rod, first connecting rod and second connecting rod are used in combination to control the movement of the bucket, thereby achieving digging and unloading soil, and the shovel teeth can play a role in increasing the grip.

When the bucket is used to unload soil, the first hydraulic cylinder rotates with the bucket, and the first hydraulic cylinder moves relative to the arc rod. At the beginning, the first piston block moves in the first hydraulic cylinder together with the support sleeve and the pulling block, so as to pump hydraulic oil into the first hydraulic cylinder. After the block is stuck in the slot, the first hydraulic cylinder continues to move relative to the arc rod. When the arc rod moves, the first compression spring is compressed. After the first compression spring is compressed to the bottom, when the first hydraulic cylinder continues to move relative to the arc rod, the pulling block pulls the supporting sleeve and the first piston block, so that the blocking block leaves the slot. After the blocking block leaves the slot, the first compression spring automatically resets, and the first piston block bounces together with the supporting sleeve. The slots are evenly spaced in the first hydraulic cylinder, and the first piston block moves intermittently in the first hydraulic cylinder. In this way, oil is pumped intermittently, and the movable block and the knocking block move back and forth, which is convenient for repeatedly knocking the bucket, and can effectively prevent soil from sticking to the inner wall of the bucket, making the soil unloading operation more complete and thorough.
