[0004] The existing technical solutions have the following drawbacks, such as: the existing tamping devices can only be used for one type of pressure regulation tamping, which is too limited, and at the same time, they are prone to wear during the pressing process, which is not conducive to increasing the pressing stability. Therefore, this utility model provides an adaptive pressure adjustment device for tamping hammer head to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide an adaptive pressure adjustment device for tamping hammers, so as to solve the problem mentioned in the background art that the existing tamping devices can only be used for one type of pressure adjustment tamping, which is too limited, and at the same time, they are prone to wear during the pressing process, which makes it difficult to increase the pressing stability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adaptive pressure adjustment device for a tamping hammer head, comprising: a mounting plate and a support plate connected to the top of the mounting plate, wherein the support plate is connected to the tamping plate via a pressure adjustment assembly, and further comprising:

[0007] The pressure regulating component is connected to a first stabilizing column at its top, and a connecting spring is nested on the outer surface of the first stabilizing column. A bearing plate is fixed to the top of the first stabilizing column.

[0008] A first stabilizing block is vertically fixed to the outer side of the support plate, and a motor is connected to the outer side of the first stabilizing block. A guide block is installed at the outer output end of the motor. A second stabilizing block is connected to the bottom of the guide block, and a connecting wheel is installed at the inner end of the second stabilizing block.

[0009] As a preferred embodiment of the present invention, the pressure regulating component includes a first connecting column disposed on the tamping plate, and the first connecting column has a positioning hole inside, and a second connecting column is connected to the upper end of the first connecting column, and a threaded rod is connected inside the second connecting column.

[0010] As a preferred embodiment of this utility model, the positioning holes are opened at equal intervals inside the first connecting post, and the first connecting post and the second connecting post are slidably arranged.

[0011] As a preferred embodiment of this utility model, the threaded rod is connected to the first connecting post and the second connecting post by means of threads.

[0012] As a preferred embodiment of this utility model, the first stabilizing column is connected to the support plate in a sliding manner via a connecting spring.

[0013] As a preferred embodiment of this utility model, the longitudinal section of the guide block is a teardrop-shaped structure, and the bottom end of the guide block is fitted with the connecting wheel.

[0014] As a preferred technical solution of this utility model, the connecting wheel and the second stabilizing block are connected by rotation, which plays a role in preventing wear on the connecting wheel and the guide block.

[0015] As a preferred embodiment of this utility model, a second stabilizing column is symmetrically arranged on the outer side of the tamping plate, and the second stabilizing column penetrates the interior of the support plate and is slidably connected to it.

[0016] As a preferred embodiment of this invention, the second stabilizing block is arranged in parallel with the first stabilizing block.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the adaptive pressure adjustment device for tamping hammer head can reduce the wear between parts during pressing by setting the guide block and connecting wheel, while the sliding of the second stabilizing column during pressing can increase the pressing stability, and the pressing distance can be adjusted by setting the adjustment component, so as to adjust the applicability according to the needs.

[0018] 1. The longitudinal section of the guide block is teardrop-shaped, and the bottom end of the guide block is fitted with the connecting wheel. By starting the installation motor, the guide block at the output end of the installation motor rotates. The first stabilizing column is connected to the support plate in a sliding manner through the connecting spring. At the same time, the connecting spring extends and retracts, causing the tamping plate below the adjustment component to move up and down for tamping.

[0019] 2. The bottom end of the guide block is fitted with the connecting wheel, and the connecting wheel and the second stabilizing block are connected by rotation, which prevents wear on the connecting wheel and the guide block. When the first stabilizing column moves up and down, the second stabilizing column slides inside the support plate, increasing the stability of movement. When the guide block rotates, the connecting wheel and the second stabilizing block are connected by rotation, so that the connecting wheel rotates inside the second stabilizing block, reducing wear between the guide block and the connecting wheel, and making it more flexible to use.

[0020] 3. Positioning holes are equally spaced inside the first connecting post, and the first and second connecting posts are slidably arranged. When the first connecting post is moved to a suitable position inside the second connecting post, the connection length between the first and second connecting posts will be adjusted since the vertical movement distance of the first stabilizing post remains unchanged, thereby adjusting the downward pressure distance. By rotating the threaded rod, the threaded rod passes through the suitable positioning hole and connects with the second connecting post, thereby increasing the stability of the second and first connecting posts after adjustment.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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] Please see Figure 1-5 This utility model provides a technical solution: an adaptive pressure adjustment device for tamping hammer head, including a mounting plate 1, a support plate 2, a tamping plate 3, a first connecting column 4, a positioning hole 5, a second connecting column 6, a threaded rod 7, a first stabilizing column 8, a connecting spring 9, a bearing plate 10, a second stabilizing column 11, a first stabilizing block 12, a second stabilizing block 13, a connecting wheel 14, a mounting motor 15, and a guide block 16.

[0029] Working principle: When using this tamping hammer head adaptive pressure adjustment device, firstly, as... Figure 1 and Figure 3In this structure, a support plate 2 is installed on the top of the mounting plate 1. After the coal is screened, it is compacted by this device to form coal cakes. The device is placed directly below the coal cake being compacted. A first stabilizing block 12 is vertically fixed to the outer side of the support plate 2, and a mounting motor 15 is connected to the outer side of the first stabilizing block 12. A guide block 16 is installed at the outer output end of the mounting motor 15. By starting the mounting motor 15, the guide block 16 at the output end of the mounting motor 15 rotates. At the same time, a first stabilizing column 8 is connected to the top of the pressure regulating component, and a connecting spring 9 is nested on the outer surface of the first stabilizing column 8. A bearing plate 10 is fixed to the top of the first stabilizing column 8. A second stabilizing block 13 is connected to the bottom of the guide block 16, and a connecting wheel 14 is installed at the inner end of the second stabilizing block 13. When the guide block 16 rotates, the longitudinal section of the guide block 16 has a teardrop-shaped structure, and the bottom end of the guide block 16 is in contact with the connecting wheel 14. When the guide block 16 rotates, it remains in contact with the connecting wheel 14 inside the second stabilizing block 13. This rotation causes the first stabilizing column 8 at the lower end of the bearing plate 10 to slide inside the support plate 2. The first stabilizing column 8 is connected to the support plate 2 via a connecting spring 9. Simultaneously, the connecting spring 9 extends and retracts, causing the tamping plate 3 below the adjusting assembly to move up and down for tamping. The second stabilizing column 11 is symmetrically arranged on the outer side of the tamping plate 3 and slides through the support plate 2. When the first stabilizing column 8 moves up and down, the second stabilizing column 11 slides inside the support plate 2, increasing the stability of the movement. When the guide block 16 rotates, the connecting wheel 14 is connected to the second stabilizing block 13 by rotation, causing the connecting wheel 14 to rotate inside the second stabilizing block 13. This reduces wear between the guide block 16 and the connecting wheel 14, making the operation more flexible.

[0030] Specific examples Figure 2 , Figure 4 and Figure 5In this assembly, the support plate 2 is connected to the tamping plate 3 via a pressure adjusting component. The pressure adjusting component includes a first connecting column 4 mounted on the tamping plate 3, with a positioning hole 5 inside the first connecting column 4. A second connecting column 6 is connected to the upper end of the first connecting column 4, and a threaded rod 7 is connected inside the second connecting column 6. When the downward pressure needs to be adjusted, the first connecting column 4 is slid within the second connecting column 6. Since the vertical movement distance of the first stabilizing column 8 remains constant, the connection length between the first connecting column 4 and the second connecting column 6 is adjusted, thereby adjusting the downward pressure distance. This assembles the pulverized coal device with the tamping device. When the distance between them remains constant, the pressure can be adjusted by pressing down. At the same time, the positioning holes 5 are equally spaced inside the first connecting column 4, and the first connecting column 4 and the second connecting column 6 are slidably arranged. When the first connecting column 4 is moved to a suitable position inside the second connecting column 6, the threaded rod 7 is connected to the first connecting column 4 and the second connecting column 6 by threads. By rotating the threaded rod 7, the threaded rod 7 passes through the suitable positioning hole 5 and connects with the second connecting column 6, thereby increasing the stability of the second connecting column 6 and the first connecting column 4 after adjustment. This is the usage method of the tamping hammer head adaptive pressure adjustment device.
