Description

Technical Field

[0001] The utility model belongs to the technical field of excavator buckets, in particular to an excavator bucket with a cleaning mechanism. Background Art

[0002] An excavator is a machine that uses a bucket to dig materials and load them into transport vehicles or unload them to stockpiles. The excavated materials are mainly soil, coal, silt, and pre-loosened rocks and ores.

[0003] Existing excavator buckets generally include a bucket and shovel teeth. During long-term use of the excavator bucket, the shovel teeth are severely worn, resulting in low earth-moving efficiency, so they need to be replaced. However, the existing bucket and shovel teeth are generally integrated. When the shovel teeth are worn and need to be replaced, the excavator bucket can only be replaced as a whole, which increases the cost of use. Utility Model Content

[0004] In order to overcome the above defects, the utility model provides an excavator bucket with a cleaning mechanism, which solves the problem that when the integrated bucket and teeth cause the teeth to wear and need to be replaced, the excavator bucket can only be replaced as a whole, which increases the cost of use.

[0005] To achieve the above object, the utility model provides the following technical solution: an excavator bucket with a cleaning mechanism, comprising a bucket body, a T-shaped rod fixedly connected to the bucket body, a connecting plate provided on the bucket body, a T-shaped slot provided on the connecting plate, and a plurality of shovel teeth fixedly connected to the connecting plate;

[0006] A fixing plate is fixedly connected to the hopper body, a threaded rod is threadedly connected to the fixing plate, and limit plates are arranged on both sides of the connecting plate, one of the limit plates is fixedly connected to the hopper body, and the other limit plate is rotatably connected to one end of the threaded rod.

[0007] As a further solution of the utility model: a protective shell is fixedly connected to one side of the hopper body, and a motor is arranged inside the protective shell.

[0008] As a further solution of the utility model: the output end of the motor is fixedly connected to a bidirectional screw rod, two movable plates are threadedly connected to the bidirectional screw rod, and cotton cloth is fixedly connected to the two movable plates.

[0009] As a further solution of the utility model: two limit rods are slidably connected to the fixed plate, and the two movable plates are slidably connected to the fixed rods.

[0010] As a further solution of the utility model: a nut is fixedly connected to one end of the threaded rod, and a brush is arranged on the movable plate.

[0011] As a further solution of the utility model: a threaded hole is provided on the movable plate, and a through hole is provided on the movable plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The excavator bucket with a cleaning mechanism is provided with a T-slot, a limit plate, a T-rod, a threaded rod and a nut. When the shovel teeth need to be disassembled, the nut is turned to drive the threaded rod to rotate, so that the threaded rod pulls the limit plate, so that the limit plate no longer blocks the connecting plate. At this time, the connecting plate can be slid out of the T-rod to complete the disassembly of the connecting plate and the shovel teeth. When installing the shovel teeth, the T-slot is clamped on the T-rod, and the connecting plate is pushed. The nut is turned to make the limit plate block the connecting plate to complete the installation of the shovel teeth. The excavator bucket is convenient for replacing the shovel teeth. When the shovel teeth are severely worn and need to be replaced, there is no need to replace the entire excavator bucket, thereby reducing the use cost.

[0014] 2. The excavator hopper with a cleaning mechanism is provided with a bidirectional screw rod, a movable plate, a motor and a brush. When it is necessary to clean the inside of the hopper body, the motor is started to drive the bidirectional screw rod to rotate, so that the two movable plates are moved closer to or farther away from each other. At the same time, since the cotton cloth is soft, the two movable plates move closer to or farther away from each other, which will cause the cotton cloth to be squeezed or stretched. At this time, the brush on the movable plate cleans the inside of the hopper body, and the bidirectional screw rod can make the two movable plates move synchronously, thereby doubling the cleaning efficiency and making it more practical.

[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0022] like Figure 1-5 As shown, the utility model provides a technical solution: an excavator hopper with a cleaning mechanism, including a hopper body 1, a T-shaped rod 10 is fixedly connected to the hopper body 1, a connecting plate 6 is provided on the hopper body 1, and a protective shell 2 is fixedly connected to one side of the hopper body 1. Because of the protective shell 2, when the hopper body 1 is shoveling soil, the protective shell 2 can block the soil to prevent the soil from entering the motor 7 and causing damage, thereby protecting the motor 7, and the motor 7 is provided inside the protective shell 2.

[0023] A T-shaped groove 12 is provided on the connecting plate 6, and a plurality of shovel teeth 5 are fixedly connected to the connecting plate 6. A fixed plate 13 is fixedly connected to the hopper body 1, and two limit rods 14 are slidably connected to the fixed plate 13. Fixed rods 9 are slidably connected to the two movable plates 4. Because the fixed rods 9 are provided, when the two movable plates 4 move, the fixed rods 9 can limit the movable plates 4, thereby improving the stability of the movement of the movable plates 4.

[0024] A threaded rod 15 is threadedly connected to the fixed plate 13, and a nut 16 is fixedly connected to one end of the threaded rod 15. Since a plurality of grooves are provided on the nut 16, friction can be increased, which makes it convenient for the staff to turn the nut 16 and improves the convenience of operation. A brush 17 is provided on the movable plate 4, a threaded hole 18 is provided on the movable plate 4, and a through hole 19 is provided on the movable plate 4.

[0025] Limiting plates 11 are provided on both sides of the connecting plate 6, one of the limiting plates 11 is fixedly connected to the hopper body 1, and the other limiting plate 11 is rotatably connected to one end of the threaded rod 15. The output end of the motor 7 is fixedly connected to a bidirectional screw rod 8, and two movable plates 4 are threadedly connected to the bidirectional screw rod 8. Cotton cloth 3 is fixedly connected to the two movable plates 4. Because the cotton cloth 3 is provided, the cotton cloth 3 can prevent mud from entering the bidirectional screw rod 8, causing the bidirectional screw rod 8 to rust, thereby protecting the bidirectional screw rod 8.

[0026] The working principle of the utility model is:

[0027] When the inside of the hopper body 1 needs to be cleaned, the motor 7 is started to drive the bidirectional screw 8 to rotate, so that the two moving plates 4 move closer to or farther away from each other. At the same time, since the cotton cloth 3 is soft, the two moving plates 4 move closer to or farther away from each other, which will cause the cotton cloth 3 to be squeezed or stretched. At this time, the brush 17 on the moving plate 4 cleans the inside of the hopper body 1;

[0028] When the shovel tooth 5 needs to be disassembled, the nut 16 is turned to drive the threaded rod 15 to rotate, so that the threaded rod 15 pulls the limit plate 11, so that the limit plate 11 no longer blocks the connecting plate 6. At this time, the connecting plate 6 can be slid out of the T-shaped rod 10, and the disassembly of the connecting plate 6 and the shovel tooth 5 is completed. When installing the shovel tooth 5, the T-shaped slot 12 is stuck on the T-shaped rod 10, and the connecting plate 6 is pushed. The nut 16 is turned to make the limit plate 11 block the connecting plate 6, and the installation of the shovel tooth 5 is completed.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0030] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
