Description

Technical Field

[0001] The present invention relates to the technical field of excavators, and in particular to an excavator and a bucket structure thereof. Background Art

[0002] The materials excavated by the excavator are mainly soil, coal, silt, and pre-loosened soil and rock. From the development of construction machinery in recent years, the development of excavators is relatively fast. Excavators have become one of the most important construction machinery in engineering construction, and the bucket is the main working part of the excavator.

[0003] Publication number CN 111535388 A discloses an excavator bucket wear-resistant structure, comprising a main body, the top of the main body is fixedly connected to a lifting ear, a plurality of slots are provided at the front end of the main body, shovel teeth are inserted in the plurality of slots, a plurality of elastic protrusions are fixedly connected to the inner side wall of the main body, a first wear-resistant plate is fixedly connected to the bottom of the main body, a second wear-resistant plate is provided at the bottom of the main body, four corners of the second wear-resistant plate are provided with L-shaped fixing plates, the L-shaped fixing plates are fixedly connected to the inside of the main body, a positioning rod is slidably inserted on the L-shaped fixing plate, the bottom end of the positioning rod passes through the second wear-resistant plate and extends into the main body, a bayonet corresponding to the positioning rod is provided on the main body, and the present invention makes the excavator bucket more wear-resistant and easier to clean by setting a detachable wear-resistant structure.

[0004] Since the bucket frequently contacts with materials such as sand and gravel, its working environment is relatively harsh and complex. During the working process, the shovel teeth frequently impact the materials, causing friction and wear between the shovel teeth and the materials. The shovel teeth in the above-mentioned prior art are fixed to the bucket by bolts, which makes the subsequent replacement of the shovel teeth more troublesome. In addition, when encountering hard rocks or materials, since the shovel teeth are directly fixed on the bucket, when the excavator is used, the driving arm is mainly used to drive the bucket to move back and forth to knock the materials for excavation. The shovel teeth themselves cannot crush the materials, resulting in low excavation efficiency. Summary of the invention

The excavating unit 100 includes a bucket body 101, and a first inner cavity 102 is formed on the inner wall at the bottom of the bucket body 101. An inner concave plate 103 is slidably connected to the first inner cavity 102, and a plurality of shovel teeth 104 are arranged in the inner concave plate 103. The crushing unit 200 includes two rectangular plates 201, and both ends of the rectangular plates 201 are fixed to the inner walls on both sides of the first inner cavity 102. The two rectangular plates 201 are slidably connected to each other. There are multiple moving rods 202, and a U-shaped plate 203 is arranged in the first inner cavity 102. One end of the multiple moving rods 202 is fixed to the U-shaped plate 203, and the other end of the multiple moving rods 202 is commonly fixed with a striking plate 213. Baffles 204 are fixed at both ends of the U-shaped plate 203, and the ends of the two baffles 204 that are away from each other are both in contact with the inner wall of the first inner cavity 102. The concave plate 103 can be embedded in the U-shaped plate 203, and a fixing component for fixing the concave plate 103 and the U-shaped plate 203 is arranged in the U-shaped plate 203.

[0039] Among them, the fixing component includes a first positioning hole 205 opened on both sides of the inner concave plate 103, and a storage cavity 206 is opened in the two ear plates of the U-shaped plate 203. A positioning column 207 is slidably connected in the storage cavity 206, and the positioning column 207 can be embedded in the corresponding first positioning hole 205. A cylindrical rod 208 is fixed at one end of the positioning column 207. The cylindrical rod 208 passes through the U-shaped plate 203 and is slidably connected to the U-shaped plate 203. The end of the cylindrical rod 208 extending to the outside of the U-shaped plate 203 is rotatably connected to a strip plate 210. A binding plate 211 is fixed on the side where the two ear plates of the U-shaped plate 203 are away from each other. A binding groove 212 is opened in the binding plate 211, and the strip plate 210 can be embedded in the binding groove 212. A first spring 209 is sleeved on the outside of the cylindrical rod 208, and one end of the first spring 209 is against the positioning column 207, and the other end of the first spring 209 is against the inner wall of the storage cavity 206.

[0040] In addition, a second inner cavity 215 and a mounting groove 216 are provided at the bottom of the bucket body 101, and the second inner cavity 215 and the mounting groove 216 are communicated with each other. A motor 217 is installed in the second inner cavity 215, and a rotating shaft 219 is fixed to the output end of the motor 217. The rotating shaft 219 passes through the bucket body 101 and rotates in the bucket body 101. An eccentric wheel 218 is fixed to one end of the rotating shaft 219 extending into the first inner cavity 102. When the eccentric wheel 218 rotates, it can squeeze the impact plate 213. A second spring 214 is sleeved on the outer side of the moving rod 202, and one end of the second spring 214 is against the impact plate 213, and the other end of the second spring 214 is against one of the rectangular plates 201.

[0041] When in use, when crushing materials, start the motor 217 to drive the rotating shaft 219 to rotate, and when the rotating shaft 219 rotates, it drives the eccentric wheel 218 to rotate, and when the eccentric wheel 218 rotates and hits the impact plate 213, it drives the impact plate 213 to move, and when the impact plate 213 moves, it compresses the second spring 214. In addition, when the impact plate 213 moves, it drives the moving rod 202 to move, and when the moving rod 202 moves, it drives the U-shaped plate 203 and the inner concave plate 103 to move, and when the inner concave plate 103 moves, it drives the shovel teeth 104 to hit the materials. When the eccentric wheel 218 rotates until it no longer squeezes the impact plate 213, at this time, under the rebound force of the second spring 214, it drives the impact plate 213, the moving rod 202, the U-shaped plate 203, and the inner concave plate 103 to move in the opposite direction, so that the shovel teeth 104 move back and forth, that is, the shovel teeth 104 can crush the materials, thereby improving the excavation efficiency.

[0042] It should be noted that the motor 217 in this embodiment is a conventional device purchased on the market and known to technicians in this field. The model can be selected or customized according to actual needs. In this patent, we only use it and do not improve its structure and function. For technicians in this field, its setting method, installation method and electrical connection method only need to be debugged according to the requirements of its instruction manual. They will not be described in detail here. The motor 217 is provided with a control switch matching it. The installation position of the control switch is selected according to actual use requirements to facilitate the operator to operate and control.

[0043] In addition, a second cover plate 220 is placed in the mounting groove 216, and second bolts 221 are passed through the four corners of the second cover plate 220, and the second bolts 221 are threadedly connected to the bucket body 101, and a first cover plate 105 is placed on the inner wall of the bottom of the bucket body 101, and the first cover plate 105 can seal the first inner cavity 102, and first bolts 106 are passed through the four corners of the first cover plate 105, and the first bolts 106 are threadedly connected to the bucket body 101, and a plurality of rectangular grooves 223 are opened in the inner concave plate 103, and the shovel teeth 104 pass through the corresponding rectangular grooves 223, and an anti-slip plate 222 is fixed to one end of the shovel teeth 104, and the length and width of the anti-slip plate 222 are both greater than the length and width of the rectangular groove 223, and a pressure plate 224 is placed in the inner concave plate 103, and the pressure plate 224 can press the anti-slip plate 222 tightly against the inner concave plate 103.

[0044] Furthermore, two chambers 225 are provided in the pressure plate 224, and positioning plates 226 are slidably connected in the two chambers 225. Second positioning holes 230 are provided on both sides of the inner concave plate 103, and the two positioning plates 226 can be respectively embedded in the corresponding second positioning holes 230. Two travel grooves 228 are provided on the pressure plate 224, and the two travel grooves 228 are respectively connected to the corresponding chambers 225. A third spring 227 is provided in the chamber 225, and one end of the third spring 227 is against the positioning plate 226, and the other end of the third spring 227 is against the inner wall of the chamber 225. A column 229 is fixed on the two positioning plates 226, and the two columns 229 are respectively slidably fitted in the corresponding travel grooves 228. Two third positioning holes 231 are provided in the U-shaped plate 203, and the two columns 229 can be respectively embedded in the corresponding third positioning holes 231.

[0045] When the shovel teeth 104 are worn and need to be replaced, first move the strip plate 210 to drive the cylindrical rod 208 to move, and the cylindrical rod 208 moves to drive the positioning column 207 to move. When the positioning column 207 moves, the first spring 209 is compressed. When the positioning column 207 is moved out of the first positioning hole 205, the strip plate 210 is rotated to be embedded in the restraining groove 212. At this time, the positioning column 207 is restrained in the storage cavity 206. Then, another positioning column 207 is restrained in the storage cavity 206 according to the above steps, and the inner concave plate 103 can be removed, and then the column is moved. 229, move the two columns 229 closer to each other so that the column 229 drives the positioning plate 226 to move. When the positioning plate 226 is moved out of the second positioning hole 230, the pressure plate 224 is taken out from the inner concave plate 103, so that the pressure plate 224 no longer conflicts with the anti-drop plate 222, and the shovel teeth 104 that need to be replaced can be replaced. This replacement method is very convenient. When the inner concave plate 103 is removed, the pressure plate 224 is taken out from the inner concave plate 103, and then the inner concave plate 103 is inverted, all the shovel teeth 104 fall out directly from the rectangular groove 223, which is convenient for replacing the shovel teeth 104.

[0046] When the shovel teeth 104 are replaced, the two cylinders 229 are moved first, so that the two cylinders 229 are close to each other. When the cylinders 229 move, the positioning plate 226 is driven to move, and the positioning plate 226 is moved into the chamber 225. At this time, the positioning plate 226 compresses the third spring 227, and then the pressure plate 224 is embedded in the inner concave plate 103, so that the pressure plate 224 and the anti-slip plate 222 are pressed tightly, and then the cylinder 229 is released. At this time, the positioning plate 226 is driven to move under the rebound force of the third spring 227, so that the positioning plate 226 is embedded in the second positioning hole 230, that is, the pressure plate 224 is fixed, so that the installation of the shovel teeth 104 is completed, and then the inner concave plate 103 is moved to the U-shaped The plate 203 is embedded in the column 229, so that the column 229 is embedded in the third positioning hole 231. At this time, the column 229 embedded in the third positioning hole 231 also plays a limiting role. When the concave plate 103 is embedded in the U-shaped plate 203, the strip plate 210 is rotated to move it out of the restraining groove 212. At this time, the positioning column 207 is driven to move under the rebound force of the first spring 209, so that the positioning column 207 is embedded in the first positioning hole 205, so that the concave plate 103 and the U-shaped plate 203 are fixed, and the column 229 is embedded in the third positioning hole 231, so that the concave plate 103 and the U-shaped plate 203 are stably fixed together, that is, the shovel teeth 104 are installed on the bucket body 101.

[0047] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
