The grate opening 2 is a hole provided on the grate plate body 1 for the passage of materials. The reinforcing rod 3 is used to enhance the overall strength and stability of the grate plate body 1, which helps prevent the grate plate body 1 from deforming or being damaged when carrying materials, and improves the service life of the grate cooler. With the cooperation of the baffle 6 and the bayonet 7, by adjusting the position of the baffle 6, the size and flow rate of the materials can be controlled.

[0024] In a further preferred embodiment of the present utility model, a plurality of threaded rods 8 are fixed on the support rod 4. A plurality of the threaded rods 8 all penetrate through the fixed sleeve 5. Threaded blocks 9 are threadedly installed on a plurality of the threaded rods 8. Shock pads are installed at the bottoms of a plurality of the threaded blocks 9, and a plurality of the shock pads can all be in contact with the outer wall of the fixed sleeve 5.

[0025] In this embodiment, the design of the support rod 4 and the threaded rod 8 makes the connection between the support rod 4 and the fixed sleeve 5 more stable and provides the possibility of adjusting the position of the support rod 4. The user rotates the threaded block 9 to move up and down on the threaded rod 8, thereby adjusting the position of the threaded block 9 relative to the fixed sleeve 5. The main function of the shock pad is to reduce the vibration and noise generated during the operation of the grate cooler, improve the stability of the equipment and the comfort of the operating environment.

[0026] In a further preferred embodiment of the present utility model, a plurality of limiting openings 11 are provided on the grate plate body 1. Limiting rods 12 are movably installed in a plurality of the limiting openings 11. A same support plate 13 is fixed on a plurality of the limiting rods 12. The support plate 13 can be in contact with the ground, and a moving wheel is detachably installed on one side of the support plate 13.

[0027] In this embodiment, the limiting openings 11 provide space for the installation and movement of the limiting rods 12, ensuring that the limiting rods 12 can move and be adjusted within a limited range. The design of the support plate 13 enables the grate plate structure to contact the ground more stably when placed or moved, increasing the stability of the equipment. The moving wheel makes it more convenient and labor-saving for the grate plate structure to move when needed, improving the portability and flexibility of the equipment.

[0028] In a further preferred embodiment of the present utility model, two clamping blocks 14 and a plurality of limiting members are respectively installed on both sides of the grate plate body 1. A plurality of the limiting members can be respectively located on both sides of the two clamping blocks 14. The limiting member is composed of a limiting plate 18 and a limiting block 17. The limiting plate 18 is fixed on the grate plate body 1. The limiting block 17 is movably installed in the limiting plate 18 and can extend into any one of the clamping blocks 14. A plurality of the limiting blocks 17 are all T-shaped.

[0029] In this embodiment, the block 14 provides a positioning point for the connection between the grate plate bodies 1, ensuring that the grate plate bodies 1 can be accurately connected together. The limiting member is composed of a limiting plate 18 and a limiting block 17, which together provide additional stability and safety for the connection between the grate plate bodies 1. The user can adjust the position of the limiting block 17 as needed. The T-shaped design increases the contact area between the limiting block 17 and the block 14, thereby improving the stability of the connection.

[0030] In a further preferred embodiment of the utility model, a plurality of mounting plates 15 are fixed to a side of the grate plate body 1 away from the clamping block 14 , and springs 16 are fixed to the plurality of mounting plates 15 . The plurality of springs 16 can be fixedly connected to the plurality of limit blocks 17 respectively.

[0031] In this embodiment, through the cooperation of the mounting plate 15 and the spring 16, the limit block 17 can automatically reset when subjected to external force, ensuring that the connection between the grate plates always remains stable. This automatic reset function reduces the need for human intervention and improves the convenience and efficiency of operation. The introduction of the spring 16 provides additional support for the limit block 17, further enhancing the connection stability between the grate plates. Even when subjected to large vibrations or impacts, the grate plates can maintain a tight connection to prevent loosening or falling off. Due to the presence of the spring 16, the limit block 17 can produce a certain buffering effect when in contact with the block 14, reducing the direct friction and wear between the two and extending the service life of the equipment.

[0032] In a further preferred embodiment of the utility model, a plurality of the springs 16 are provided with limiting telescopic rods, the plurality of the limiting telescopic rods are respectively fixed on a plurality of the limiting blocks 17 , and the plurality of the limiting telescopic rods are respectively fixedly connected to a plurality of the mounting plates 15 .

At the same time, it also provides additional support for the entire grate plate structure, enhancing the stability of the structure. Due to the guiding effect of the limiting telescopic rod, the contact between the limiting block 17 and the clamping block 14 is more uniform, reducing the wear caused by friction, which helps to extend the service life of the equipment. The cooperation between the limiting telescopic rod and the spring 16 enables the limiting block 17 to be quickly reset when subjected to external force without manual intervention, which improves the convenience and efficiency of operation.

[0034] In a further preferred embodiment of the utility model, a plurality of clamping strips 10 are installed on a side of the grate plate body 1 away from the reinforcing rod 3, the grate plate body 1 is an arc-shaped plate, and the side sections of the plurality of clamping strips 10 are all triangular.

[0035] In this embodiment, by installing a plurality of card strips 10, the grate plate body 1 can isolate relatively loose materials, prevent the materials from accumulating at one point, increase the evenness of the force on the device, and the arc design of the grate plate body 1 enables it to better adapt to the structure and working state of the traveling grate, which helps to reduce wear and faults caused by equipment mismatch and improve the overall performance and service life of the equipment.

[0036] In summary, compared with the related art, in this device, by setting a plurality of reinforcing rods 3, the strength of the grate plate body 1 can be increased; by setting the threaded rod 8 cooperating with the threaded block 9, the fixing sleeve 5 can be stably fixed, so that baffles 6 of different sizes can be replaced, so as to adjust the size of the grate opening 2 and the discharge speed of materials of different sizes; by setting the spring 16 to abut against the limit block 17, the limit block 17 can be kept located within the clamping block 14, so that two grate plate bodies 1 can be connected together.
