Description

Technical Field

[0001] This utility model relates to the field of refractory brick processing technology, specifically a feeding device for porous refractory brick kilns. Background Technology

[0002] Refractory bricks are high-temperature refractory materials with excellent refractoriness and high-temperature strength. They are widely used in the construction of various industrial furnaces, heating equipment, and furnaces in industries such as steel, non-ferrous metals, and ceramics. Refractory bricks can be classified by shape and size into standard bricks, ordinary bricks, and special-shaped bricks; by manufacturing process into fired bricks, unfired bricks, electrofused bricks (cast bricks), and refractory insulating bricks; and by application into blast furnace refractory bricks, hot blast stove refractory bricks, and coke oven refractory bricks.

[0003] An investigation revealed that a Chinese utility model or invention patent (publication number: CN221561766U) discloses a feeding device for a porous refractory brick kiln, comprising connecting blocks, connecting shafts, a base plate, support legs, a placement plate, hydraulic cylinders, and support plates. Four connecting blocks are provided, each fixed at one of the four corners of the lower end face of the base plate. Two connecting shafts are provided, located at opposite ends of the lower end face of the base plate, with their ends positioned at the middle of the connecting blocks. Both ends of the connecting shafts are movably mounted with casters on their outer sides. Four hydraulic cylinders are provided, fixed at one of the four corners of the upper end face of the base plate, with hydraulic rods movably mounted on their upper ends. Two support plates are provided, located on either side of the upper part of the base plate. This utility model offers the advantage of facilitating the transport of brick blanks during refractory brick firing.

[0004] While the aforementioned patent has the advantage of facilitating the transport of brick blanks during the firing of refractory bricks through the setting of connecting blocks, it is difficult to achieve the effect of lifting the material box and increasing the tilt angle of the material box to realize the effect of automatic material unloading. This results in the need for manual unloading, which is time-consuming and labor-intensive and needs to be improved.

[0005] Therefore, this utility model provides a feeding device for porous refractory brick kilns to solve the above problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides a feeding device for a porous refractory brick kiln, such as... Figures 1-5 As shown, the feeding mechanism 1 includes a base 101. A lead screw 102 passes through one side of the base 101 and is rotatably connected to the lead screw 102. A roller 103 passes through the end of the lead screw 102 away from the base 101 and is fixedly connected to the roller 103. A handle 104 is fixedly connected to one side of the base 101. A rotating rod 105 is rotatably connected to the side of the base 101 away from the handle 104. A material box 106 is fixedly connected to the circumference of the rotating rod 105. A lifting mechanism 2 is provided outside the feeding mechanism 1. The lifting mechanism 2 includes a cylinder 201. The cylinder 201 is fixedly connected to the side of the base 101 near the handle 104. The cylinder 201 is slidably connected to the push rod 202 through an internal piston. A sliding groove A203 is provided at the bottom of the material box 106.

[0029] A slider 204 is slidably connected to the inner wall of the chute A203. A short rod A205 is fixedly connected to one side of the slider 204. A connecting plate A206 passes through the end of the short rod A205 away from the slider 204 and is rotatably connected to the connecting plate A206. A short rod B207 passes through the side of the connecting plate A206 near the short rod A205 and is rotatably connected to the short rod B207. The above design is beneficial to changing the tilt angle of the material box 106 so as to pour the material.

[0030] There are two rollers 103, which are symmetrical about each other along the vertical central axis of the lead screw 102. The bottom of the material box 106 is in contact with the top of the base 101. The above design facilitates the handling of materials by using the two rollers 103.

[0031] The feeding mechanism 1 is externally provided with a cover opening mechanism 3. The cover opening mechanism 3 includes a fixing rod 301. One end of the fixing rod 301 is fixedly connected to the side of the base 101 near the rotating rod 105. The top of the material box 106 is rotatably connected to a positioning rod 302. A top cover 303 is fixedly connected to the circumference of the positioning rod 302. A fixing plate 304 is fixedly connected to the top of the top cover 303. A sliding groove B305 is opened on the side of the fixing plate 304 near the top cover 303. A positioning block 306 is slidably connected to the inner wall of the sliding groove B305. A connecting rod A308 is fixedly connected to the end of the positioning block 306 away from the sliding groove B305. A connecting plate B307 is rotatably connected to one end of the connecting rod A308. A connecting rod B309 is rotatably connected to the end of the connecting plate B307 away from the connecting rod A308. The above design is conducive to automatic cover opening when pouring materials.

[0032] The end of the fixing rod 301 away from the base 101 is fixedly connected to the circumferential surface of the connecting rod B309. The fixing rod 301 is L-shaped, and there are two fixing rods 301, which are symmetrical to each other along the vertical central axis of the base 101. The above design is conducive to lifting the connecting rod B309 by fixing rod 301.

[0033] There are two fixing plates 304, which are symmetrical to each other along the vertical central axis of the top cover 303. The fixing rod 301 is located between the base 101 and the roller 103. The above design helps to prevent the roller 103 from being obstructed by the fixing rod 301 when it rotates.

[0034] The end of the push rod 202 away from the cylinder 201 is rotatably connected to the circumferential surface of the short rod B207. There are two connecting plates A206, which are symmetrical to each other along the vertical central axis of the material box 106. The above design is conducive to pushing the short rod B207 to make vertical displacement by the push rod 202.

[0035] The working process of this utility model is as follows: This application uses a cylinder 201 to drive a push rod 202 to move vertically, thereby causing the push rod 202 to push a short rod B207 to move vertically, which in turn causes the short rod B207 to drive a connecting plate A206 to move vertically, which in turn causes the connecting plate A206 to drive a short rod A205 to move vertically, which in turn causes the short rod A205 to drive a slider 204 to slide in a groove A203 in a material box 106, thereby causing the material box 106 to tilt at an angle via a rotating rod 105, thus lifting the material box 106 and increasing the tilt angle of the material box 106, thereby achieving the effect of automatic material unloading without the need for manual unloading, saving time and effort;

[0036] Simultaneously, when the material box 106 is tilted at an angle by the rotating rod 105, the material box 106 drives the positioning rod 302 to move in a circular motion along the rotating rod 105. This causes the positioning rod 302 to drive the top cover 303 to move in a circular motion, which in turn causes the top cover 303 to drive the fixing plate 304 to move in a circular motion. This causes the fixing plate 304 to drive the positioning block 306 to move in a circular motion, which in turn causes the positioning block 306 to drive the connecting rod A308 to move in a circular motion. This causes the connecting rod A308 to drive the connecting rod B309 to move in a circular motion through the connecting plate B307. At this time, the connecting rod B309 will be subjected to the stress of the fixing rod 301, which will push the top cover 303. This causes the top cover 303 to rotate through the positioning rod 302, achieving the effect of automatically opening the cover when the material box 106 is unloaded.

[0037] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
