Description

Technical field:

[0001] The utility model relates to the technical field of celadon processing equipment, and more particularly to a clay tamping device. Background technology:

[0002] After the existing raw clay for celadon is excavated, it needs to be hammered to make the clay finer.

[0003] The original hammering was done manually, which was inefficient and required a lot of labor. Therefore, a mechanical hammering device was used for automatic hammering. The existing hammering equipment generally has a connecting block fixed on a hammering rod, a rotating shaft installed on a frame on one side, a cam or a toggle block fixed on the rotating shaft, and the toggle block rotates by rotating the rotating shaft. When the toggle block rotates, the connecting block is lifted, so that the hammering rod is lifted. When the toggle block is separated from the connecting block, the hammering rod is lowered to achieve hammering. Since the toggle block is in direct contact with the connecting block, it is easy to wear, and when the toggle block rotates, its end will slide along the bottom surface of the connecting block, causing friction between the two and easy damage.

[0004] Moreover, the existing hammer rod rises and falls directly, and the impact force is too large, which has too great an impact on the base plate, making it easy to be damaged. Utility model content:

[0005] The purpose of the present utility model is to address the deficiencies of the existing technology and to provide a clay tamping device. A wear-resistant plate is fixed to the bottom surface of the horizontal portion, and a roller is movably connected to the end of the extension portion of the turning frame through a bearing. The roller is pressed against the wear-resistant plate for lifting, and the device has little wear and is not easily damaged. In addition, the buffer spring has a buffering effect on the descent of the vertical main rod, thereby reducing the impact on the bottom plate and improving the service life.

[0006] The technical solutions of this utility model are as follows:

[0007] A clay tamping device comprises a placement base plate, support columns are fixed to the front and rear of the left and right sides of the top surface of the placement base plate, the two ends of the front transverse beam are fixed to the upper inner side walls of the two front support columns, a rear support frame is fixed to the middle of the rear wall surface of the front transverse beam, and the rear support frame is provided with two front and rear guide rollers, the two ends of the guide rollers are movably connected to the left and right side plates of the rear support frame through bearings, and a vertical main rod is inserted between the two guide rollers;

A turning frame is fixed in the middle of the main rotating shaft, and the end of the extension part of the turning frame is movably connected to a roller body through a bearing, and the roller body faces the bottom surface of the horizontal part.

[0011] The top end of the vertical main rod extends out of the top surface of the rear support frame and is fixed with an upper fixed horizontal plate. The top surface of the rear support frame is fixed with two baffles extending left and right. The top surface of the baffle is fixed with multiple buffer springs, and the top ends of all buffer springs are applied to the bottom surface of the upper fixed horizontal plate.

[0012] The bottom of the vertical main rod is connected with an extension sleeve through a flange, and a cylindrical punching and tamping head is installed at the bottom of the extension sleeve.

[0022] Example: See Figures 1 to 4 As shown, a clay tamping device includes a placing base plate 10, a rear baffle 1 is fixed to the rear part of the top surface of the placing base plate 10, and side baffles 2 are fixed to the left and right parts of the top surface of the placing base plate 10, and the left and right sides of the rear baffle 1 are fixed to the rear inner wall of the two side baffles 2. The front and rear parts of the left and right sides of the top surface of the placing base plate 10 are fixed with support columns 11, and the support columns 11 are located on the top surface of the placing base plate 10 between the two side baffles 2. The two ends of the front transverse beam 12 are fixed to the upper inner wall of the two front support columns 11, and the middle part of the rear wall surface of the front transverse beam 12 is fixed with a rear support frame 13, and the rear support frame 13 is provided with front and rear two guide rollers 14. The two ends of the guide roller 14 are movably connected to the left and right side plates of the rear support frame 13 through bearings, and the vertical main rod 20 is inserted between the two guide rollers 14;

[0023] The bottom of the vertical main rod 20 extends out of the bottom surface of the rear support frame 13 and is fixedly mounted with a stamping and tamping head 30, which faces the bottom plate 10;

[0024] A connecting sleeve 21 is fixed to the middle of the vertical main rod 20, and a horizontal portion 22 extending backward is formed on the rear side wall of the connecting sleeve 21;

[0025] An intermediate connecting beam 15 is provided in the middle of the two corresponding front and rear support columns 11. The front and rear ends of the intermediate connecting beam 15 are fixed on the side walls of the corresponding two support columns 11. A bearing seat 16 is fixed in the middle of the top surface of the intermediate connecting beam 15. The main rotating shaft 17 is fixed on the inner rings of the bearings of the two bearing seats 16. A turning frame 18 is fixed in the middle of the main rotating shaft 17. The end of the extended part of the turning frame 18 is movably connected to a roller body 19 through a bearing, and the roller body 19 faces the bottom surface of the horizontal part 22.

[0026] Furthermore, an annular groove is formed in the middle of the roller body 19, and the left and right side walls of the annular groove are arc-shaped walls, and the vertical main rod 20 is located in the two annular grooves. This can reduce the amplitude of the left and right deviation of the vertical main rod 20 when it is raised and lowered.

[0027] Specifically, the top end of the vertical main rod 20 extends beyond the top surface of the rear support frame 13 and is secured to an upper fixed horizontal plate 23. Two baffles 131 extending left and right are secured to the top surface of the rear support frame 13. Multiple buffer springs 132 are secured to the top surfaces of the baffles 131. The top ends of all buffer springs 132 press against the bottom surface of the upper fixed horizontal plate 23. When the vertical main rod 20 descends, the buffer springs 132 press against the bottom surface of the upper fixed horizontal plate 23, thereby reducing the impact force of the vertical main rod 20 descending and the impact force of the ramming head 30 on the base plate 10, thereby increasing its service life.

[0028] Furthermore, the bottom of the vertical main rod 20 is connected to an extension sleeve 40 through a flange, and a cylindrical stamping tamping head 30 is installed at the bottom of the extension sleeve 40.

[0029] Furthermore, the front wall surface of the bottom of the rear baffle 1 and the rear top surface where the base plate 10 is placed are fixed with connecting blocks 3 extending left and right with the front wall surface being an inclined surface.

[0030] Furthermore, a radial annular portion 41 is formed on the inner side wall of the bottom end of the extension sleeve 40, and a telescopic shaft 42 is inserted into the extension sleeve 40. A small-diameter shaft portion 43 extending downward is formed in the middle of the bottom surface of the telescopic shaft 42. The small-diameter shaft portion 43 is inserted into the middle through hole of the radial annular portion 41. The bottom edge of the telescopic shaft 42 is pressed against the top surface of the radial annular portion 41. The bottom end of the small-diameter shaft portion 43 extends out of the bottom end of the radial annular portion 41 and is fixed with the ramming head 30.

[0031] A main buffer spring 5 is inserted into the extension sleeve 40. The bottom end of the main buffer spring 5 presses against the top surface of the telescopic shaft 42, while the top end of the main buffer spring 5 presses against the bottom surface of the flange plate at the bottom end of the vertical main rod 20 above the extension sleeve 40. The main buffer spring 5 also cushions the downward impact of the ramming head 30, thereby reducing the impact force on the placement base 10.

[0032] Furthermore, a wear-resistant plate 6 is fixed to the bottom surface of the horizontal portion 22, and the bottom surface of the wear-resistant plate 6 corresponds to the top surface of the roller body 19. This structure prevents the roller body 19 of the extension portion of the turning frame 18 from directly colliding or rubbing against the horizontal portion 22 of the connecting sleeve 21, thereby improving the service life of both.

[0033] When this embodiment is in use, both ends of its main rotating shaft 17 extend out of the corresponding bearing seats 16 and are connected to the output shaft of an external driving motor (which is a conventional structure and not shown in the accompanying drawings). The main rotating shaft 17 is driven to rotate by the driving motor. When rotating, when it is flipped through the flip frame 18, its roller body 19 is pressed against the wear-resistant plate 6, lifting the connecting sleeve 21, so that the vertical main rod 20 is lifted. Then, as the flip frame 18 flips, the roller body 19 is separated from the wear-resistant plate 6. At this time, the vertical main rod 20 descends due to its own weight, so that the punching head 30 hammers the clay placed at the corresponding position on the top surface of the base plate 10, making it more delicate. When the vertical main rod 20 descends, it reduces the impact through the buffer spring 132 and the main buffer spring 5.
