[0028] like Figure 1-4As shown, the present application provides a hammer crusher discharging grate plate, including an arc-shaped grate plate frame 1, a grate plate body 2 is provided on the arc-shaped grate plate frame 1, the grate plate body 2 is formed by splicing a plurality of grate plate strips 21, a grate gap 3 is provided between two adjacent grate plate strips 21, locking components 4 are provided at both ends of the arc-shaped grate plate frame 1, and a reinforcing component 5 is provided at the bottom of the grate plate body 2, the grate plate body 2 is fixed to the arc-shaped grate plate frame 1 through the locking component 4, and the grate plate body 2 is formed by splicing a plurality of grate plate strips 21, when wear occurs, one or several grate plate strips 21 can be replaced separately according to the wear position, effectively reducing the production cost, and the reinforcing component 5 can provide support for the grate plate body 2 and accept the impact of materials on the grate plate body 2, thereby extending the service life of the grate plate body 2 and reducing the replacement of the grate plate body 2. Frequency, the locking assembly 4 includes a pressing plate 41 and a locking piece 42, a connector 411 is fixedly provided at the bottom of the pressing plate 41, a through hole 11 compatible with the connector 411 is provided on the arc-shaped grate frame 1, the connector 411 passes through the through hole 11, and a locking hole 412 is provided at the end of the connector 411 away from the pressing plate 41, the locking piece 42 is inserted into the locking hole 412 and is located at the lower end of the through hole 11, when replacing the worn grate strip 21, the locking piece 42 is pulled out of the locking hole 412, and then the pressing plate 41 is lifted upward to separate the connector 411 from the through hole 11, and then the grate strip 21 is taken out and replaced with a new grate strip 21, after the replacement is completed, the connector 411 of the pressing plate 41 is inserted into the through hole 11, and then the locking piece 42 is inserted into the locking hole 412, and the installation and replacement are simple.

[0029] like Figure 3 and Figure 4 As shown, there are two plug-in connectors 411 , which are symmetrically arranged. Through the cooperation of the two plug-in connectors 411 and the locking member 42 , the installation of the pressure plate 41 is more stable.

[0030] The reinforcing assembly 5 includes a first connecting member 51, a second connecting member 52 and a plurality of reinforcing ribs 53. The first connecting member 51 is fixedly arranged at one end of the reinforcing rib 53, and the second connecting member 52 is fixedly arranged at the other end of the reinforcing rib 53. The reinforcing rib 53 is fixedly arranged on the arc-shaped grate plate frame 1 through the first connecting member 51 and the second connecting member 52. The reinforcing rib 53 is arc-shaped, and the curvature of the upper end surface of the reinforcing rib 53 is adapted to the curvature of the lower end surface of the grate plate body 2.

Specifically, the first connecting member 51 and the second connecting member 52 are both welded to the arc-shaped grate plate frame 1. The reinforcing rib 53 is arranged in three numbers, which can strengthen the support for the grate plate body 2.

[0031] like Figure 2 and Figure 3 As shown, the reinforcing ribs 53 are perpendicular to the grate gaps 3, so that each reinforcing rib 53 can support a plurality of grate slats 21. While providing effective support, the number of reinforcing ribs 53 can be reduced, thereby saving production costs.

[0032] like Figure 2 As shown, the cross section of the grate slot 3 is narrow at the top and wide at the bottom. Specifically, the cross section of the grate slot 3 is an isosceles trapezoid that is narrow at the top and wide at the bottom, which can allow qualified materials to pass quickly and reduce the friction of the materials on the grate strips 21 during the passing process, thereby extending the service life of the grate strips 21.

[0033] like Figure 2 As shown, a wear-resistant layer 6 is provided on the top of the grate strip 21. The provision of the wear-resistant layer 6 can prevent the material from directly rubbing against the top of the grate strip 21, thereby extending the service life of the grate strip 21. In this embodiment, the wear-resistant layer 6 is made of tungsten carbide and has good wear resistance.

[0034] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
