DETAILED DESCRIPTION

[0027] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] like Figure 1 As shown: a bucket wheel excavator chute plate with a good service life, a mesh plate 1 is arranged on the side of the chute plate that contacts the material.

[0029] The surface of the chute plate of the bucket wheel excavator currently in use has no protective layer. During the long-term working process, the scouring of materials causes serious wear of the contact surface between the chute plate and the materials, and the replacement of the chute plate is very troublesome. Therefore, the utility model adopts the method of arranging a mesh plate 1 on the surface of the chute plate, so that a part of the material falling into the chute plate is retained in the mesh plate 1. After the mesh plate 1 is filled with materials, the materials in the subsequent work will scour the materials retained in the mesh plate 1, so that the materials that should have been scoured with the contact surface between the chute plate and the materials are scoured with the materials retained in the mesh plate 1, thereby adding an extra protective layer between the contact surface between the chute plate and the materials, avoiding direct contact between the materials and the chute plate and the materials, reducing the wear of the chute plate itself, and increasing the service life of the chute plate. In addition, the mesh plate 1 itself is easy to replace. When the mesh plate 1 is severely worn, it can be directly replaced, reducing the labor intensity of personnel.

[0030] like Figure 1 and Figure 5 As shown: it includes a first connecting plate 11, a second connecting plate 12, a hanging rod 13, a hook 14 and a reinforcing rib 15; the first connecting plate 11 is arranged at the top of the material sliding plate; the second connecting plate 12 is arranged at the top of the mesh plate 1; the hanging rod 13 is arranged on the first connecting plate 11; the hook 14 is arranged on the second connecting plate 12, and the hook 14 is connected to the hanging rod 13 in cooperation; the reinforcing rib 15 is arranged on the first connecting plate 11, and one side of the reinforcing rib 15 is in contact with the contact surface of the mesh plate 1 and the material sliding plate.

[0031] When the mesh plate 1 is laid flat on the surface of the material sliding plate, in order to avoid relative sliding between the mesh plate 1 and the material sliding plate, the hook 14 on the second connecting plate 12 bolted to the top of the mesh plate 1 and the hanging rod 13 on the first connecting plate 11 bolted to the top of the material sliding plate are matched and connected, so that the mesh plate 1 is in contact with the surface of the material sliding plate through the cooperation of the hook 14 and the hanging rod 13, and no relative sliding occurs. Furthermore, since the mesh plate 1 itself has a certain weight, and the hanging rod 13 will be subjected to continuous force through the hook 14 connected to the mesh plate 1 during operation, increasing the load of the hanging rod 13. In order to avoid bending of the first connecting plate 11 connected to the hanging rod 13, a reinforcing rib 15 is provided on the first connecting plate 11, and one side of the reinforcing rib 15 is in contact with the contact surface of the mesh plate 1 and the material sliding plate. The reinforcing rib 15 strengthens the load capacity of the first connecting plate 11. Further, the load capacity of the hanging rod 13 is enhanced, thereby ensuring the stability of the mesh plate 1 during operation.

[0032] like Figures 1 to 8 As shown: the grid plate 1 is composed of multiple grid units 4 spliced ​​together by a connecting mechanism 3.

[0033] Since the specifications of the material sliding plates are different, for some material sliding plates with larger specifications, the specifications of the required mesh plates 1 are also larger and the scope of application is relatively single. Therefore, in the present application, a splicable mesh plate 1 is designed, and the mesh plate 1 is divided into multiple mesh units 4 for splicing, thereby increasing the scope of application of the mesh plate 1. Specifically, a connecting mechanism 3 is provided between two mesh units 4 to splice the two mesh units 4 together. Furthermore, multiple mesh units 4 are spliced ​​together through the connecting mechanism 3 to increase the specifications of the mesh plate 1, so that the mesh plate 1 is adapted to material sliding plates of different specifications.

[0034] like Figures 1 to 4 As shown: the connecting mechanism 3 includes: a connecting block 31, a groove 32 and a connecting rod 33; the groove 32 is arranged at the connection between two adjacent grid units 4; the connecting rod 33 is arranged inside the groove 32; the connecting block 31 is provided with a hole for the connecting rod 33 to pass through, and the connecting block 31 is rotatably connected to the connecting rod 33.

[0035] On the material sliding plate, two connected grid units 4 are hinged by a connecting block 31. During non-working hours, the grid units 4 do not need to be laid flat on the surface of the material sliding plate. The grid units 4 can be folded in a "z" shape through the connecting piece. By folding the grid units 4, the floor space occupied by the folded units can be reduced, which facilitates the storage of the grid units 4. Furthermore, during work, only the head and tail grid units 4 need to be stretched to lay the entire grid plate 1 flat on the surface of the material sliding plate.

[0036] like Figure 1 and Figure 3 As shown: a fixing mechanism is provided between the grid units 4; the fixing mechanism includes a C-shaped clamping block 36 and a socket 37; the socket 37 is arranged at a certain distance from the connection between two adjacent grid units 4; the C-shaped clamping block 36 is plugged into the socket 37 arranged at a certain distance from the connection between two adjacent grid units 4.

[0037] When the grid plate 1 composed of multiple grid units 4 is laid flat on the material sliding plate, in order to avoid relative rotation between the multiple grid units 4, the C-shaped clamping block 36C is inserted into the socket 37 provided on two adjacent grid units 4, so that the grid units 4 no longer produce relative rotation, thereby ensuring the stability of the grid units 4 during operation.

[0038] like Figures 6 to 8As shown: the connecting mechanism 3 also includes a slot 34 and an insert block 35; the slot 34 is arranged on one of the connecting surfaces between the grid unit 4 and the grid units 4 before and after it; the insert block 35 is arranged on the other connecting surface opposite to the slot 34, and the slot 34 and the insert block 35 can be plugged in; the connecting mechanism 3 also includes a positioning pin 38, a first positioning hole 391 and a second positioning hole 392; the positioning hole 391 is arranged on the slot 34, and the second positioning hole 392 is arranged on the insert block 35; the positioning pin 38 can be plugged into the first positioning hole 391 and the second positioning hole 392.

[0039] For the grid plate 1 laid flat on the surface of the material slide plate, the utility model provides another connecting mechanism 3 for the grid units 4 constituting the grid plate 1. Specifically, the plug block 35 of the grid unit 4 is inserted into the slot 34 of another grid unit 4 until the first positioning hole 391 on the slot 34 and the second positioning hole 392 on the plug block 35 are in a coaxial position. At this time, the positioning pin 38 is inserted into the first positioning hole 391 and the second positioning hole 392, so that the two adjacent grid units 4 can be stably connected without relative movement. In addition, since the grid plate 1 is formed by plugging a plurality of grid units 4, it is convenient in installation and storage.

[0040] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
