The vibrating device consists of a vibrating motor, a rotating shaft, and a vibrating hammer. The vibrating motor drives the rotating shaft to rotate, and a number of vibrating hammers are evenly fixed on the rotating shaft. The dust collecting rod connected to the filter screen passes through the outer wall of the kiln tail boiler. In this way, when the vibrating motor drives the vibrating hammer to rotate with the rotating shaft, the vibrating hammer will alternately hit the dust collecting rod, and the filter screen is driven to vibrate through the dust collecting rod to achieve the falling of dust and attached materials on the filter screen.

[0003] However, the existing rapping hammer is easy to be damaged, which is caused by the structure of the existing rapping hammer. The existing rapping hammer is composed of a column, two fixing plates and two bolts. The two fixing plates are located on both sides of the column, and the column serves as a hammer head. The fixing plate and the column are connected by two bolts. In this way, when the column as the hammer head repeatedly hits the dust collecting rod periodically, each time the column hits the column, it will shear the bolts, resulting in the bolts connecting the column and the fixing plate breaking after a period of time, affecting the normal dust removal of the boiler at the end of the kiln.

[0004] At the same time, the connecting rod for connecting the rapping hammer and the rotating shaft is fixed on the rotating shaft by welding, which makes the position of the rapping hammer on the rotating shaft unadjustable. When the rapping hammer is not aligned with the dust collecting rod, it is very difficult to adjust. Summary of the invention

[0005] In order to overcome the disadvantages of the above technical problems, the utility model provides a kiln tail boiler vibrating hammer and a vibrating device formed by the vibrating hammer.

[0006] The utility model discloses a kiln tail boiler rapping hammer, comprising a hammer head and two hammer handles, wherein the hammer head is in a cylindrical shape, the hammer handles are in a plate shape, the two hammer handles are parallel to each other, the hammer head is fixed to one end of the two hammer handles, the other ends of the two hammer handles are provided with a first bolt hole, and a containing cavity is formed between the two hammer handles; the utility model is characterized in that: the hammer head and the two hammer handles are integrally formed castings.

[0007] The utility model discloses a kiln tail boiler vibrating hammer, comprising a connecting rod connected to a hammer handle, wherein the lower end of the connecting rod is located in an accommodating cavity, and the lower end of the connecting rod is hinged to the hammer handle via a first bolt passing through a first bolt hole and the lower end of the connecting rod; a limiting block is fixed on the outer surface of the conical handle, a block-shaped bolt head is arranged at one end of the first bolt, and the lower surface of the block-shaped bolt head is a limiting plane in contact with the upper surface of the limiting block.

[0008] The utility model discloses a kiln tail boiler rapping hammer, wherein the upper end of the connecting rod is provided with a cylindrical cavity matched with a rotating shaft in the rapping device, the upper part of the cylindrical cavity is provided with a slot, a second bolt hole is provided on the connecting rod at the slot, and a countersunk bolt for locking the connecting rod to the rotating shaft is provided in the bolt hole.

[0009] The utility model discloses a rapping device composed of a rapping hammer for a kiln tail boiler, comprising a rapping motor, a rotating shaft and a chain transmission mechanism, wherein both ends of the rotating shaft are fixed on the outer surface of the kiln tail boiler via bearings and bearing seats, the rapping motor and the kiln tail boiler are both fixed on a foundation, the rapping motor drives the rotating shaft to rotate via the chain transmission mechanism, dust collecting rods are arranged at equal intervals on the kiln tail boiler below the rotating shaft, the hammer handle is hinged on a connecting rod, the rotating shaft is inserted into a cylindrical cavity on the connecting rod, and the connecting rod is fastened to the rotating shaft by countersunk bolts.

[0010] The beneficial effects of the utility model are as follows: the kiln tail boiler vibrating hammer of the utility model is composed of a cylindrical hammer head and two plate-shaped hammer handles, the two hammer handles are arranged in parallel, one end of the two hammer handles is connected to the hammer head, and the other end is provided with a first bolt hole, and the hammer head and the hammer handle are an integrally formed casting. Since the hammer head and the hammer handle are an integrally formed casting, the structure is very strong, and will not be damaged during the long-term continuous striking of the dust collecting rod.

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1 and Figure 2 As shown, the front view and the right view of the existing rapping hammer are respectively given, which is composed of a cylinder 21, two fixing plates 22 and two second bolts 23. The lower ends of the two fixing plates 22 are located on both sides of the cylinder 21, and the fixing body 21 and the two fixing plates 22 are fixed together by the two second bolts 23. During the use of the rapping hammer composed of the cylinder 21, the fixing plate 22 and the second bolts 23, the cylinder 21 will continuously hit the dust collecting rod on the boiler at the end of the kiln. During the hitting process, the cylinder 21 will produce a shearing effect on the second bolts 23. With long-term use, the second bolts 23 are easily sheared and broken, which affects the service life of the rapping hammer.

[0022] like Figure 3 and Figure 4 As shown, the front view and the left view of the utility model of the kiln tail boiler rapping hammer are respectively given, which is composed of a hammer head 1 and two hammer handles 2. The hammer head 1 is cylindrical, the hammer handle 2 is plate-shaped, the two hammer handles 2 are parallel to each other, and there is a receiving cavity 4 between the two hammer handles 2. The upper ends of the two hammer handles 2 are provided with a first bolt hole 3, and the lower ends of the two hammer handles 2 are connected to the hammer head 1, and the hammer head 1 and the two hammer handles 2 are an integral casting. The structure of the integral hammer head 1 and the two hammer handles 2 is more solid, and no damage will occur during the long-term striking of the dust collecting rod 16 on the kiln tail boiler, making the rapping hammer durable.

[0023] like Figure 5 and Figure 6As shown, the front view and the left view of the kiln tail boiler rapping hammer of the utility model after being connected with the connecting rod are given, the hammer handle 2 is connected with the connecting rod 6, the upper end of the hammer handle 2 of the rapping hammer is hinged to the lower end of the connecting rod 6 through the first bolt 7, the upper end of the connecting rod 6 is provided with a cylindrical cavity 8, and the rotating shaft 18 of the rapping device is inserted into the cylindrical cavity 8 to achieve the fixing of the connecting rod 6 on the rotating shaft 18. A slot 11 is provided on the connecting rod 6 at the upper part of the cylindrical cavity 8, and the slot 11 divides the end of the connecting rod 6 into two pieces. A second bolt hole 9 is provided on the connecting rod 6 at the slot 11, and the second bolt hole 9 is provided with a countersunk bolt 10. In this way, after the rotating shaft 18 is inserted into the cylindrical cavity 8 of the connecting rod 6, the connecting rod 6 can be tightly fixed on the rotating shaft 18 by locking the countersunk bolt 10. It can be seen that by loosening or tightening the countersunk bolt 10, the position of the connecting rod 6 on the rotating shaft 18 can be adjusted so that the rapping hammer connected to the connecting rod 6 is aligned with the dust collecting rod 16 on the kiln tail boiler 15.

[0024] A limiting block 5 is fixed on the outer side of a hammer handle 2, the limiting block 5 is close to the second bolt hole 9, and a block-shaped bolt head 12 is provided at one end of the first bolt 7, and the lower surface of the block-shaped bolt head 12 is a limiting plane 13 that matches the upper surface of the limiting block 5. In this way, the limiting plane 13 of the block-shaped bolt head 12 is limited by the upper surface of the limiting block 5, thereby avoiding the relative rotation of the hammer handle 2 and the first bolt 7. Since the hammer handle 2 and the first bolt 7 cannot rotate relative to each other, the rapid wear of the first bolt 7 is avoided, and the service life of the first bolt 7 is extended.

[0025] like Figure 7 As shown, a schematic diagram of the structure of the rapping device composed of the rapping hammer of the kiln tail boiler of the utility model is given. The rapping device shown is composed of a rapping motor 17, a rotating shaft 18 and a chain rotating mechanism 20.

The rapping motor 17 and the kiln tail boiler 15 are fixed on the foundation 14. A plurality of dust collecting rods 16 are arranged at equal intervals below the rotating shaft 18. The inner ends of the dust collecting rods 16 are fixed to the filter screen inside the kiln tail boiler, and the outer ends of the dust collecting rods 16 pass through the body wall of the kiln tail boiler. The rapping motor 17 drives the rotating shaft to rotate through the chain transmission mechanism 20. For the connecting rods 6 on adjacent rapping hammers, their fixing angles on the rotating shaft 18 are different.

[0026] The hammer handle 2 shown is hinged on the connecting rod 6 via the first bolt 7, and the connecting rod 6 is fixed on the rotating shaft via the countersunk bolt 10. In this way, when the rapping device 17 drives the rotating shaft 18 to rotate via the chain transmission mechanism 20, the connecting rod 6 and the rapping hammer can be driven to rotate, so that the cone head 1 on the rapping hammer raps the dust collecting rod 16 aligned with it, so as to realize the dust removal effect on the filter screen inside the kiln tail boiler 15.
