[0002] The tamping machine is a special machine for tamping coke ovens used to tamp coal briquettes. The briquette tamping machine is usually composed of a main machine, a hydraulic system, an electronic control system, etc. The main machine includes tamping arms, tamping hammers, coal plates, drive mechanisms and other components. The briquette tamping machine drives the tamping arms and tamping hammers through the hydraulic system to tamp the coal into briquettes of a certain shape and density as required. During the tamping process of briquettes, the tamping hammer makes the coal more solid and compact through high-frequency vibration. The tamping machine has the advantages of high degree of automation, high production efficiency, uniform density of briquettes, and labor saving. For factories and coal mines that produce briquettes in large quantities, the use of briquette tamping machines can improve production efficiency, reduce labor costs, and improve product quality.

[0003] However, since the coal will be scattered everywhere in the coal box when it is fed into the coal box, and the hammer rod and hammer head in the existing tamping machine only move up and down in the vertical direction to hammer the coal at the bottom, it is impossible to collect the surrounding coal and then hammer it. Therefore, it is necessary to stop the machine and manually move the material before hammering it again. This operating efficiency is low and it has certain risks. Utility Model Content

DETAILED DESCRIPTION

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0020] A three-hammer tamping machine, such as Figures 1 to 4 As shown, it includes a bracket 1, on which three hammer rods 2 are installed side by side, a hammer head 3 is arranged at the bottom of the hammer rod 2, a material shifting assembly for shifting material at the bottom of the hammer head is installed on the hammer rod 2 located above the hammer head 3, a hammer lifting assembly connected to the hammer rod 2 is arranged at the upper part of the bracket 1, and a hammer stopping assembly for stopping the hammer rod is arranged at the lower part of the bracket 1.

[0021] like Figure 2 As shown, the hammer lifting assembly includes a hammer lifting cylinder 4 connected to the hammer rod 2 above the bracket 1 through an articulated seat 5, wherein the articulated seat 5 is arranged on the hammer rod 2, and the hammer rod 2 is also provided with a connecting rod seat 7, the connecting rod seat 7 is hinged to the first connecting rod 6, the other end of the first connecting rod 6 is hinged to the second connecting rod 8, and the other end of the second connecting rod 8 is connected to the hammer lifting cylinder 4.

[0022] When the hammer cylinder 4 is extended or retracted, the first connecting rod 6 is driven to rotate around the connecting rod seat 7 through the extension or retraction of the second connecting rod 8, thereby driving the connecting rod seat 7 and the hammer rod 2 to slide up and down along the bracket 1 to complete the hammering action.

[0023] The hammer stop assembly includes cams 15 symmetrically mounted on both sides of the hammer rod 2 through a bearing seat 14. Figure 3 As shown, a sector rack 17 is provided on the side of the cam 15 opposite to the protrusion, and a driven gear 16 coaxially arranged with the cam 15 is also installed on the bearing seat 14. The driven gear 16 is meshed with the sector rack 17 for transmission. At the same time, the driven gear 16 is driven by the gear box 10, and the gear box 10 is connected to the motor 9.

[0024] Two driving gears 18 meshing with each other are symmetrically arranged in the gear box 10 . The driving gear 18 meshes with the driven gear 16 for transmission, but there is a certain gap between the two driven gears 16 .

[0025] The motor 9 drives the gear box 10 to move, and the two driving gears 18 rotate in opposite directions, and drive the driven gear 16 to move. The driven gear 18 is meshed with the fan-shaped rack 17 for transmission, thereby driving the cam 15 to rotate relatively, so that its protruding part contacts the surface of the hammer rod 2 to clamp the hammer rod 2, so that the hammer rod 2 stops moving, and the hammer is stopped.

[0026] The material shifting assembly includes a mounting sleeve 11 rotatably mounted at the bottom of the hammer rod 1, a shifting rod 12 is hinged at the bottom of the mounting sleeve 11, and the middle part of the shifting rod 12 is connected to an adjusting cylinder 13 arranged at the bottom of the mounting sleeve 11. When material shifting is required, the shifting rod 12 is pushed by the adjusting cylinder 13 to rotate around the mounting sleeve 11, and the coal is shifted to the bottom of the hammer head 3 so as to be hammered into coal cakes. At the same time, the mounting sleeve 11 drives the shifting rod 12 to rotate around the center of the hammer rod 2, so that the coal within a certain range around the hammer head 3 can be shifted.

[0027] The bracket 1 is also provided with a lubrication assembly 19 which is in communication with the gear box 10 and can replenish lubricating oil into the gear box 10 in time to ensure the stability of the transmission.

[0028] When in use, the tamping machine is installed inside the coal box, and then the hammer rod and the hammer head are driven to slide up and down along the bracket through the hammer lifting assembly to hammer and compact the coal below, and then the feeding mechanism is used to continuously transport the coal into the coal box and hammer the coal into coal cakes. At the same time, the coal scattered around the hammer head is pushed to the bottom of the hammer head through the material shifting assembly for hammering, which is convenient and quick, and reduces the number of shutdown operations.

[0029] The utility model provides a three-hammer tamping machine, which is used to pluck coal scattered around the hammer head by arranging a material shifting assembly, thereby solving the problem of needing to stop the machine for manual material shifting due to coal scattered around the hammer head during feeding, reducing the number of times the machine is stopped for material shifting, and improving the tamping efficiency of the tamping machine. At the same time, the hammer stop assembly is provided to clamp and limit the hammer rod, thereby preventing the hammer rod from continuing to move downward under the action of gravity, thereby improving the safety of the entire device.
