[0001] The utility model belongs to the technical field of shoveling plates, and particularly relates to a novel shoveling plate. Background Art

[0002] The function of the grate-kiln machine is to sequentially pass qualified green balls through several technological sections such as the air extraction drying section and the preheating section, so as to complete the dehydration, preheating, and oxidation functions, meet the requirements for entering the rotary kiln, and then send them into the rotary kiln through the shoveling plate of the grate-kiln machine. The shoveling plate is installed at the shoveling tip of the grate-kiln machine and is used to send the material unloaded from the grate bed into the rotary kiln;

[0003] During the shoveling process of the shoveling plate, wear will occur at its shoveling tip. After being used for a period of time, when the wear amount of the shoveling tip of the shoveling plate reaches a certain degree, the whole shoveling plate can only be replaced, which reduces the utilization rate of the equipment and increases the production cost. Content of the Utility Model

[0004] The utility model provides a novel shoveling plate, aiming to solve the problem that the currently used shoveling plate cannot dry the shoveling tip alone, thereby reducing the utilization rate of the shoveling plate as proposed in the above background art.

[0005] To solve the above problems, the utility model is realized as follows. A novel shoveling plate includes: a shoveling plate body and a shoveling tip part arranged on one side of the shoveling plate body; a group of T-shaped grooves respectively opened on one side of the shoveling plate body and the shoveling tip part; an I-shaped rod slidably installed in the group of T-shaped grooves; a group of connecting blocks respectively fixedly installed on the tops of the shoveling plate body and the shoveling tip part; fixing bolts threadedly installed on the group of connecting blocks; and a positioning mechanism arranged on the shoveling plate body for positioning the I-shaped rod.

[0006] Preferably, the positioning mechanism includes: a connecting groove opened in the shoveling plate body; a fixing block fixedly installed in the connecting groove; a positioning rod slidably installed on the fixing block, and the positioning rod slidably extends into the T-shaped groove and is slidably connected with the I-shaped rod; a compression spring and a retaining piece sleeved on the fixing positioning rod, and two ends of the compression spring are respectively fixedly connected with the connecting groove and the retaining piece.

[0007] Preferably, a heat insulation layer is arranged in the connecting groove, and the material of the heat insulation layer is ceramic fiber.

[0008] Preferably, a fixing frame is fixedly installed at the bottom of the shoveling plate body, and a serpentine tube is installed on the fixing frame and closely adheres to the bottom of the shoveling plate body.

[0009] Preferably, a connecting steel plate is assembled on the shoveling tip part, the connecting steel plate is arranged in a V shape, and the material of the connecting steel plate is alloy wear-resistant steel.

[0010] Preferably, a base is provided below the shovel plate body, a group of support rods are installed on the base, the top end of any one of the support rods is hinged to the bottom of the shovel plate body, a hydraulic cylinder is fixedly installed on the other support rod, the hydraulic cylinder and the bottom of the shovel plate body are hinged with connecting rods, and connecting springs are installed on the two connecting rods.

[0011] Preferably, a protective cover is fixedly mounted on the top end of the connecting rod, and the protective cover is arranged on the connecting spring and is in sliding contact with the other connecting rod.

[0012] Compared with the related art, the new shovel board provided by the utility model has the following beneficial effects:

[0013] 1. By replacing the shovel tip on the shovel plate body separately, the service life of the shovel plate body can be effectively extended, and the replacement is convenient. The I-beam is positioned by the positioning rod to ensure that it will not move in the T-slot, which is conducive to the connection of the shovel tip. The setting of the heat insulation layer can effectively reduce the temperature in the connection groove, so that the compression spring is not easily deformed, which is conducive to the operation of the positioning mechanism. At the same time, the material of the heat insulation layer is ceramic fiber, which has the advantages of light weight, high temperature resistance, and low thermal conductivity.

[0014] 2. Water cooling the shovel plate body through the serpentine pipe can reduce the temperature of the shovel plate body, which is beneficial to prolong the service life of the shovel plate body and avoid frequent replacement. At the same time, it can also reduce the scratching phenomenon of the chain grate caused by deformation. The material of the connecting steel plate is alloy wear-resistant steel, which has excellent wear resistance and can effectively slow down the wear speed of the shovel tip, thereby effectively extending the replacement frequency of the shovel tip, which is beneficial to reduce production costs;

[0015] 3. The force of the shovel tip sliding down is buffered by the connecting spring, which can ensure that there is no rigid collision when the shovel tip contacts the chain grate, which is beneficial to the protection of the chain grate. The connecting spring is limited by the protective cover, and the connecting rod is guided at the same time to ensure that the connecting rod moves smoothly, which is beneficial to the hydraulic cylinder driving the shovel plate body to move.

[0016] Compared with the prior art, the new shovel plate provided by the present invention can replace the shovel tip alone, thereby effectively extending the service life of the shovel plate body and also reducing the production cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] An embodiment of the present utility model provides a new type of material shoveling plate, as Figures 1-5As shown in the figure, the new material shoveling plate includes: a material shoveling plate body 1 and a shovel tip part 2 arranged on one side of the material shoveling plate body 1; a group of T-shaped grooves 3 respectively opened on one side of the material shoveling plate body 1 and the shovel tip part 2; an I-shaped rod 4 slidably installed in the group of T-shaped grooves 3; a group of connecting blocks 5 respectively fixedly installed on the tops of the material shoveling plate body 1 and the shovel tip part 2; fixing bolts 6 threadedly installed on the group of connecting blocks 5; a positioning mechanism arranged on the material shoveling plate body 1 for positioning the I-shaped rod 4.

[0026] In this embodiment, when the material shoveling plate body 1 is in use, when the shovel tip part 2 is worn to a certain extent, the shovel tip part 2 can be replaced separately. When replacing, first operate the positioning mechanism to stop the positioning of the I-shaped rod 4 by the positioning mechanism. Then, remove the I-shaped rod 4 from the material shoveling plate body 1 and the shovel tip part 2. Then, remove the fixing bolt 6 from the connecting block 5. Then, the shovel tip part 2 can be removed for replacement. The replacement is relatively fast. By separately replacing the shovel tip part 2 on the material shoveling plate body 1, the service life of the material shoveling plate body 1 can be effectively extended, and at the same time, the replacement is relatively convenient.

[0028] In this embodiment, when removing the I-shaped rod 4 from the material shoveling plate body 1, first pull the positioning rod 9 to drive the retaining piece to slide synchronously along the fixing block 8, drive one end of the compression spring 10 to move by the retaining piece, stretch the compression spring 10, and slide the positioning rod 9 away from the card slot of the I-shaped rod 4. Then, the I-shaped rod 4 can be removed. The positioning rod 9 positions the I-shaped rod 4 to ensure that it will not move in the T-shaped groove 3, which is beneficial to the connection operation of the shovel tip part 2.

[0029] In a further preferred embodiment of the present invention, a heat insulation layer 11 is arranged in the connecting groove 7, and the material of the heat insulation layer 11 is ceramic fiber.

[0030] In this embodiment, through the arrangement of the heat insulation layer 11, the temperature in the connecting groove 7 can be effectively reduced, so that the compression spring 10 is not easily deformed, which is beneficial to the operation of the positioning mechanism. At the same time, since the material of the heat insulation layer 11 is ceramic fiber, ceramic fiber has the advantages of light weight, high temperature resistance, low thermal conductivity, etc.

[0031] In a further preferred embodiment of the present utility model, a fixing frame 12 is fixedly installed at the bottom of the material shoveling plate body 1, a serpentine pipe 13 is installed on the fixing frame 12, and the serpentine pipe 13 is closely attached to the bottom of the material shoveling plate body 1.

[0032] In this embodiment, when the material shoveling plate body 1 is in use, first connect the two ends of the serpentine pipe 13 to the circulating water cooling system, so that the circulating water cooling system cools the material shoveling plate body 1 by water through the serpentine pipe 13, thereby reducing the temperature of the material shoveling plate body 1, which is beneficial to extending the service life of the material shoveling plate body 1, avoiding frequent replacement, and at the same time, it can also reduce the scraping phenomenon of the chain grate caused by deformation. By performing water cooling operation on the material shoveling plate body 1 through the serpentine pipe 13, the temperature of the material shoveling plate body 1 can be reduced, which is beneficial to extending the service life of the material shoveling plate body 1, avoiding frequent replacement, and at the same time, it can also reduce the scraping phenomenon of the chain grate caused by deformation.

[0033] In a further preferred embodiment of the present utility model, a connecting steel plate 14 is assembled on the shovel tip 2, the connecting steel plate 14 is arranged in a V shape, and the material of the connecting steel plate 14 is alloy wear-resistant steel.

[0034] In this embodiment, since the material of the connecting steel plate 14 is alloy wear-resistant steel, and the alloy wear-resistant steel has excellent wear resistance, it can effectively slow down the wear speed of the shovel tip 2, thereby effectively extending the replacement frequency of the shovel tip 2, which is beneficial to reducing production costs.

[0035] In a further preferred embodiment of the present utility model, a base is arranged below the material shoveling plate body 1, a group of support rods 15 are installed on the base, the top end of any one of the support rods 15 is hinged to the bottom of the material shoveling plate body 1, a hydraulic cylinder 16 is fixedly installed on the other support rod 15, and connecting rods 17 are hinged to both the hydraulic cylinder 16 and the bottom of the material shoveling plate body 1, and a connecting spring 18 is installed on the two connecting rods 17.

[0036] In this embodiment, when the chain grate performs the blanking operation on the material, first start the hydraulic cylinder 16 to drive the connecting rod 17 to contract, and then the connecting rod 17 drives the material shoveling plate body 1 to slide down, so that the material shoveling plate body 1 drives the shovel tip 2 to move and contact the output belt of the chain grate. When the shovel tip 2 touches the chain grate, the connecting spring 18 stretches, thereby buffering the shovel tip 2 to ensure that the shovel tip 2 does not impact the chain grate. By buffering the force of the shovel tip 2 sliding down through the connecting spring 18, it can be ensured that when the shovel tip 2 touches the chain grate, there will be no rigid collision, which is beneficial to the protection of the chain grate.

[0037] In a further preferred embodiment of the present utility model, a protective cover 19 is fixedly installed at the top of the connecting rod 17. The protective cover 19 covers the connecting spring 18 and is in sliding contact with the other connecting rod 17.

[0038] In this embodiment, when the connecting spring 18 is stretched, the protective cover 19 slides along the connecting rod 17, thereby limiting the connecting spring 18 to ensure that the connecting spring 18 does not skew. By limiting the connecting spring 18 with the protective cover 19 and guiding the connecting rod 17 at the same time, the smooth movement of the connecting rod 17 is ensured, which is beneficial to the hydraulic cylinder 16 to drive the shoveling plate body 1.

[0039] In summary, compared with the related art, the present device can replace the shovel tip 2 alone, thereby effectively extending the service life of the shoveling plate body 1 and reducing the production cost at the same time.

[0040] In several embodiments provided by the present application, it should be understood that the disclosed device can be implemented in other ways.
