Description

Technical Field

[0001] The present application relates to the technical field of excavators, and in particular to a positioning device for the tip of an excavator bucket tooth. Background Art

[0002] An excavator, also known as an excavation machine and an earth mover, is an earthwork machine that uses a bucket to excavate materials above or below the machine surface and loads them into a transport vehicle or unloads them onto a stockpile.

[0003] During construction, an excavator usually uses an excavator auxiliary system to observe the construction scope. The excavator auxiliary system can enable the excavator to achieve high-efficiency operation. It is connected to a tablet through a positioning antenna installed on the excavator cab with the help of a communication harness, and the detected data is transmitted into the tablet in real time and finally displayed on the screen of the tablet in the form of animation, voice, and warning lights, showing the excavator within the construction scope and providing construction reference.

[0004] The structure of an excavator bucket includes: a bucket housing, a tooth plate, and a tooth tip sleeved on the tooth plate.

[0005] However, the excavator auxiliary system can only display the position of the cab on the screen of the tablet, and the excavator bucket is in front of the cab, and the driver needs to observe by himself whether the bucket exceeds the construction scope, which is very inconvenient. To solve this technical problem, a positioning device for the tip of an excavator bucket is needed. Utility Model Content

[0006] Aiming at the deficiencies existing in the prior art, the purpose of the present application is to provide a positioning device for the tip of an excavator bucket to solve the technical problem that the excavator auxiliary system in the prior art can only display the position of the cab on the screen of the tablet.

[0007] The above object of the present application is achieved through the following technical solutions: A positioning device for the tip of an excavator bucket includes a bucket housing, a tooth plate, and a tooth tip sleeved on the tooth plate. A signal transmitter is arranged inside the tooth tip, and a storage box fixedly connected to the tooth tip is arranged inside the tooth tip, and the signal transmitter is placed in the storage box.

[0008] By adopting the above technical solutions, the tooth tip equipped with the signal transmitter is sleeved on the tooth plate, and the signal transmitter transmits data to the tablet, and the tablet displays the position of the tooth tip for the driver to refer to, thus solving the problem that the driver needs to observe by himself whether the bucket exceeds the construction scope.

[0009] Further, a guide piece extends out inside the tooth tip, the guide piece is located in front of the opening of the storage box, and the wire of the signal transmitter is fixedly connected to the guide piece.

[0010] By adopting the above technical solution, the signal transmitter is located inside the tooth tip. Since the tooth tip is made of alloy steel, the signal sent by the signal transmitter located inside the alloy steel cannot be sent out due to the barrier of the alloy steel. Therefore, the signal transmitter wire is fixedly connected to the guide piece, and the alloy steel is turned into a conductor through the guide piece, and the signal is sent out through the alloy steel.

[0011] Further, one side of the opening of the storage box is rotatably connected with a cover plate, and a fixing device is provided at one end of the cover plate that is not rotatably connected to the storage box.

[0012] By adopting the above technical solution, during the working process of the excavator, the bucket will move up and down. The signal transmitter placed in the storage box will fall out of the storage box and shake inside the tooth tip due to the movement of the bucket. If it shakes inside the tooth tip, it will cause the signal transmitter to continuously pull the wire and damage the wire. The setting of the cover plate solves this technical problem. After the signal transmitter is placed in the storage box, the cover plate is used to cover the opening of the storage box, and then the fixing device is used to fixedly connect the end of the cover plate that is not rotatably connected to the storage box to the storage box, so that the signal transmitter is enclosed in the storage box and will not fall out of the storage box due to the movement of the bucket.

[0013] Further, a through hole is provided on the surface of the cover plate close to the guide piece.

[0014] By adopting the above technical solution, after the cover plate covers the guide hole of the storage box, the wire of the signal transmitter placed in the storage box can extend out from the through hole to connect to the guide piece.

[0015] Further, an iron platform extends out of the storage box on the outer side of the side of the storage box far from the connected cover plate. The fixing device includes two fixing plates. The two fixing plates are fixedly connected to one end of the cover cloth that is not rotatably connected to the storage box. The two fixing plates are penetrated by a rotating rod, and the rotating rod is rotatably connected to the fixing plates. The rotating rod extends out an extension plate towards the iron platform, and a positioning magnet is fixedly connected to one end of the extension plate far from the rotating rod.

[0016] By adopting the above technical solution, after the cover plate covers the opening of the storage box, rotate the extension plate so that the positioning magnet attracts the iron platform, and the purpose of fixing the end of the cover plate that is not rotatably connected to the storage box to the storage box is achieved.

[0017] Further, connecting plates extend out towards the tooth plate on both sides of the opening of the tooth tip, and threaded holes are provided in the two connecting plates. Threaded holes are provided at one end of the tooth plate close to the bucket housing. The connecting plate and the tooth plate are penetrated by a bolt, and one end of the bolt passing through the connecting plate and the tooth plate is sleeved with a nut.

[0018] By adopting the above technical solution, the connection of the tooth tip sleeve to the tooth plate is not very stable. Therefore, after passing the bolt through the connecting plate and the tooth plate, the nut is screwed onto one end of the bolt passing through the connecting plate and the tooth plate, achieving the purpose of fixing the tooth tip and the tooth plate together.

[0019] Furthermore, the two connecting plates are respectively located on the same side and the opposite side of the tooth tip where the storage box is provided.

[0020] By adopting the above technical solution, there is a certain space left on the side of the tooth tip sleeve on the tooth plate where the storage box is provided due to the storage box being provided inside the tooth tip. Assuming the storage box is provided on the lower side inside the tooth tip while the connecting plates are respectively provided on the left and right sides of the tooth tip, then the space left on the lower side inside the tooth tip after sleeving the tooth tip on the tooth plate will cause the tooth tip to shake up and down on the tooth plate. Therefore, when the connecting plates are respectively located on the same side and the opposite side of the tooth tip where the storage box is provided, the two sides where the connecting plates are pressed by the nut and the bolt will be fixed on the tooth plate without shaking.

[0021] Furthermore, a back plate for connecting the excavator robotic arm is provided at the upper end of the bucket housing.

[0022] By adopting the above technical solution, the bucket can be connected to the excavator through the back plate.

[0023] In summary, the present application includes at least the following beneficial technical effects.

[0024] 1. By sleeving the tooth tip equipped with the signal transmitter on the tooth plate and the conducting piece fixedly connected to the signal transmitter wire turns the alloy steel into a conductor through the conducting piece, and the signal is sent out through the alloy steel.

[0025] 2. Through the cover plate and the fixing device provided on the cover plate, the purpose of enclosing the signal transmitter in the storage box is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Example, referring to Figure 1 , an excavator bucket tooth tip positioning device includes a bucket housing, a toothed plate 5, and a tooth tip 1 sleeved on the toothed plate 5. A signal transmitter is arranged inside the tooth tip 1. A storage box 2 fixedly connected to the tooth tip 1 is arranged inside the tooth tip 1. The signal transmitter is placed in the storage box 2. A guide piece 10 extends out of the tooth tip 1. The guide piece 10 is located in front of the opening of the storage box 2. The wire 11 of the signal transmitter is fixedly connected to the guide piece 10. The signal transmitter turns the tooth tip 1 into a conductor through the guide piece 10 and transmits data to the tablet, achieving the purpose of displaying the position of the tooth tip on the tablet for the driver to observe conveniently.

[0034] During the working process of the excavator, the bucket will move up and down. The signal transmitter placed in the storage box 2 will fall out of the storage box 2 and shake inside the tooth tip 1 due to the movement of the bucket. If it shakes inside the tooth tip 1, it will cause the signal transmitter to continuously pull the wire 11 and damage the wire 11. To solve this technical problem, referring to Figure 2 , Figure 3 , Figure 4 , Figure 5 , in this embodiment, support plates 20 extend out of the upper and lower ends on one side of the opening of the storage box 2 towards the outside of the storage box 2. The two support plates 20 are penetrated by a rotating column 30. The rotating column 30 is fixedly connected with a cover plate 3. One end of the cover plate 3 is fixedly connected to the rotating column 30, and the other end is provided with a fixing device 4. An iron platform 21 extends out of the outside of the storage box 2 at the end of the storage box 2 far from the rotating column 30. The fixing device 4 includes two fixing plates 40. The two fixing plates 40 are fixedly connected to the end of the cover plate 3 far from the rotating column 30. The two fixing plates 40 are penetrated by a rotating rod 41. The rotating rod 41 extends towards the iron platform 21 with an extension plate 42. A positioning magnet 43 is fixedly connected to the end of the extension plate 42 far from the rotating rod 41. A through hole is opened on the surface of the cover plate 3 close to the guide piece 10. After placing the signal transmitter in the storage box 2, rotate the cover plate 3 to cover the opening of the storage box 2, then pull the wire 11 out of the through hole to the outside of the storage box 2 and connect it to the guide piece 10, and then rotate the extension plate 42 to make the positioning magnet 43 attract the iron platform 21, thus solving the problem that the signal transmitter will fall out of the storage box 2.

[0035] One end of the tooth tip 1 close to the tooth plate 5 is provided with a receiving box 2. On one side of the receiving box 2 and the side opposite thereto, connecting plates 12 extend towards the tooth plate 5. Threaded holes 50 are formed in the two connecting plates 12. A threaded hole 50 is formed at one end of the tooth plate 5 close to the bucket housing. The connecting plate 12 and the tooth plate 5 are penetrated by a bolt 51. One end of the bolt 51 passing through the connecting plate 12 and the tooth plate 5 is sleeved with a nut 52. The connection of the tooth tip 1 sleeved on the tooth plate 5 is not very stable. After the bolt 51 passes through the connecting plate 12 and the tooth plate 5, the nut 52 is screwed into one end of the bolt 51 passing through the connecting plate 12 and the tooth plate 5, achieving the purpose of fixing the tooth tip 1 and the tooth plate 5 together. Moreover, the connecting plates 12 located on one side of the tooth tip 1 where the receiving box 2 is provided and the side opposite thereto can prevent the tooth tip 1 from shaking on the tooth plate 5. A back plate 6 for connecting the excavator robotic arm is provided at the upper end of the bucket housing. Mounting holes are formed in the back plate 6. The bucket can be mounted on the excavator through the back plate 6.

[0036] Specific implementation process: First, place the signal transmitter into the receiving box 2, and then pass the wire 11 through the through hole and connect it to the guide piece 10.

[0037] Then rotate the cover plate 3 to cover the opening of the receiving box 2, and then rotate the extension plate 42 so that the positioning magnet 43 attracts the iron platform 21.

[0038] Then sleeve the tooth tip 1 on the tooth plate 5 and align the threaded holes 50. Pass the bolt 51 through them and screw the nut 52 onto one end of the bolt 51 passing through them. Finally, mount the bucket on the excavator robotic arm through the back plate 6.
