[0021] like Figure 1-4 As shown, a multi-condition convertible electric shovel bucket device includes a bucket body 101, a pair of side plate assemblies 102, and a drive unit. The bucket body 101 is a rectangular shell with an opening on the front side wall. The front end of the bottom of the bucket body 101 is designed as a toothed shovel plate 104. The pair of side plate assemblies 102 are symmetrically arranged on the left and right sides of the front side wall of the bucket body 101 and are rotatably connected to the bucket body 101. The drive unit is mounted on the bucket body 101 and can drive the pair of side plate assemblies 102 to rotate 0-180 degrees in the opening direction. The side panel assembly 102 includes a triangular short plate 1021, a triangular long plate 1022, and a rectangular plate 1023. Both the triangular short plate 1021 and the triangular long plate 1022 are right-angled plates, and their vertical right-angled sides are fixedly connected. A hinge rod 105 is fixedly installed at the connection point between the triangular short plate 1021 and the triangular long plate 1022. Hinge sleeves 106 are respectively provided on the left and right sides of the front sidewall of the bucket body 101, and the hinge rod 105 is rotatably disposed within the hinge sleeves 106. The rectangular plate 1023... The rectangular plate 1023 is horizontally designed, and one side of the rectangular plate 1023 is fixedly connected to the horizontal right-angle side of the triangular long plate 1022. Before the side plate assembly 102 rotates, the front end of the rectangular plate 1023 is in a straight line with the front end of the toothed shovel 104. After the side plate assembly 102 rotates 180 degrees, the front end of the rectangular plate 1023 is engaged with the front end of the toothed shovel 104. The rear end of the rectangular plate 1023 is designed as a sloping shovel 107. The inner sidewalls of the left and right sidewalls of the bucket body 101 are designed with hidden grooves 103 that are the same shape as the triangular short plate 1021. After the side plate assembly 102 rotates 180 degrees, the triangular short plate 1021 is engaged in the hidden groove 103; the front end of the rectangular plate 1023 is provided with meshing teeth 108 that can mesh with the toothed shovel plate 104; the triangular short plate 1021 and the triangular long plate 1022 are integrally formed; the driving component is a pair of motors, which are fixedly installed on the top of the bucket body 101 and corresponding to the position of the hinge rod 105, and the output end of the motor is fixedly connected to the hinge rod 105; the inclination angle of the ramp shovel plate 107 is 45 degrees.
[0022] Its detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, as follows:
[0023] According to the instruction manual Figure 1-4It can be seen that the side panel assembly 102 in this utility model is in a working state before rotation, that is, in the open state, such as... Figure 3 As shown, the triangular elongated plate 1022 is attached to the outer side of the left and right side walls of the bucket body 101, and the front end of the rectangular plate 1023 is flush with the front end of the toothed shovel plate 104, in a straight line. At this time, the toothed shovel plate 104 is the main working shovel plate; after the side plate assembly 102 rotates 180 degrees, it enters another working state, that is, the closed state, as shown... Figure 4 As shown, the triangular short plate 1021 is attached to the inner side of the left and right side walls of the bucket body 101. The front end of the rectangular plate 1023 is fastened to the front end of the toothed shovel 104. The rear end of the rectangular plate 1023 is designed as a 45-degree angled slope to serve as a ramp bucket. After the rectangular plate 1023 is rotated 180 degrees, its rear end becomes the front end, that is, the ramp shovel 107 is the main working shovel. The operator can select the opening or closing state of the side plate assembly 102 according to the characteristics of the loaded material to adapt to different loading conditions and smoothly load the material into the bucket, thus expanding the working capacity of the bucket. During rotation, the driving component can drive a pair of side plate assemblies 102 to rotate 0-180 degrees towards the opening direction, with both sides working symmetrically simultaneously. This utility model mainly studies the design of the side plate assembly 102. The driving component is not shown in the accompanying drawings, but existing technology can be used, such as a motor. The motor is fixedly installed on the top of the bucket body 101 and corresponds to the position of the hinge rod 105. The output end of the motor is fixedly connected to the hinge rod 105. The operation of the motor drives the hinge rod 105 to rotate, thereby driving the side plate assembly 102 to rotate. The selection and installation of the motor are common knowledge to those skilled in the art. In addition, during loading, the closing angle of the side plate assembly 102 can be controlled by the driving component, so that the triangular short plate 1021 can gather loose materials, improving loading efficiency. Figure 1 As shown, during the unloading process, the triangular short plate 1021 can also intercept the material to a certain extent by controlling the closing angle as described above, thereby controlling the feeding speed. At the same time, the triangular short plate 1021 plays a buffering role in the unloading of large-volume and heavy materials (the material is at the rear of the hopper 101, and when it is tilted, it is intercepted at the front by the triangular short plate 1021, and finally the triangular short plate 1021 is opened to release the material).
[0024] The inner sidewalls of the left and right sidewalls of the bucket body 101 are designed with hidden grooves 103 that are the same shape as the triangular short plate 1021. After the side plate assembly 102 rotates 180 degrees, the triangular short plate 1021 is engaged in the hidden grooves 103. When the inclined bucket is in working state, there will be no problem of material jamming. At the same time, it also increases the stability of working in this state.
[0025] The rectangular plate 1023 has a meshing tooth 108 at its front end that can mesh with the toothed shovel plate 104, which improves the stability of the inclined bucket in operation and prevents material leakage.
[0026] Among them, the triangular short plate 1021 and the triangular long plate 1022 are integrally molded to enhance the strength of the side plate assembly 102.
[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
