Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the range protected by the utility model.

[0031] Those skilled in the art will understand that the combination of features of different embodiments means that they are within the scope of the present application and form different embodiments, although some embodiments herein include certain features rather than others included in other embodiments. For example, in the claims, any one of the claimed embodiments can be used in any combination.

[0032] Reference will now be made, by way of example, to the accompanying drawings in which Figure 1 to the drawings Figure 5 A spade plate turner is described.

[0033] In the manufacture of spades, first, the raw material is cut according to the size of the spade plate, and the plate material is cut into a plate material. The spade plate is marked with a "LOGO" using a mechanical punch. Then the spade plate is placed in a heating furnace for high temperature softening. The spade plate after high temperature softening is turned over. The turned over spade plate is stamped into a spade head shape, and the spade head is simultaneously rolled into trousers, forming a "spade trousers" connected to the spade handle. Then the spade is heat treated to improve the hardness and toughness of the spade plate. After heat treatment, the spade is sprayed with anti-rust paint, electroplated or polished. The spade handle is inserted into the spade trousers and fixed. The finished spade is checked for strength and balance by hand or machine. After passing the test, it is packed and stored in the warehouse.

[0034] However, in the early manufacture of spades, the processing of the spade plate mainly relied on manual operation or semi-mechanized equipment, which had the following problems:

[0035] Manual turning: workers need to manually adjust the direction of the spade plate during stamping, bending or welding, which is low in efficiency and labor-intensive.

[0036] Slow production rhythm: due to reliance on manual intervention, production speed is limited, making it difficult to meet the demand for large quantities of orders.

[0037] To improve production efficiency, the manufacturing industry has gradually introduced automatic turning mechanisms, and the main technical developments include:

[0038] Pneumatic / hydraulic turner, through hydraulic positioning, using pneumatic clamps to clamp the spade plate, and through a rotary cylinder to achieve 180° turning, but the turning time is long, and after the pressing and rolling of the trousers are completed, it affects the temperature of the spade plate during heat treatment.

[0039] Therefore, the shovel plate turner comprises a support frame 1 and a turner assembly 2 rotatably arranged on the support frame 1, and the turner assembly 2 is configured to rotate from a first position to a second position under the gravity of the shovel plate. Specifically, after the shovel plate is heated and softened by the heating furnace 7, the heated and softened shovel plate is transported to above the turner by the conveying roller 71, and then the heated and softened shovel plate falls on the turner assembly 2 from the conveying roller 71. When the heated and softened shovel plate falls on the turner assembly 2 from the conveying roller 71, the turner assembly 2 rotates from the first position to the second position under the gravity of the shovel plate. The shovel plate on the turner assembly 2 rotates synchronously, and when the shovel plate rotates synchronously with the turner assembly 2, the shovel plate rotates synchronously by itself due to its own gravity, so that the shovel plate is turned over.

[0040] The turner assembly 2 comprises a first support part 21 and a second support part 22. The first support part 21 is configured to receive the shovel plate transported from the conveying device and support the first side of the shovel plate when the turner assembly 2 is in the first position. The second support part 22 is configured to receive the shovel plate turned over from the first support part 21 and support the second side opposite to the first side of the shovel plate when the turner assembly 2 rotates to the second position. Specifically, when the heated and softened shovel plate falls on the turner assembly 2 from the conveying roller 71, the shovel plate first slides along the first support part 21 to the bottom end of the turner assembly 2 under the action of its own gravity, and at this time, the first side of the shovel plate is in contact with the first support part 21. After the shovel plate contacts the bottom end of the turner assembly 2, the turner assembly 2 rotates from the first position to the second position under the gravity of the shovel plate. While the shovel plate rotates with the turner assembly 2, the shovel plate rotates synchronously by itself under the action of its own gravity, with the point of contact with the bottom end of the turner assembly 2 as the center. Then, the shovel plate is turned over from the first side in contact with the first support part 21 to the second side in contact with the second support part 22, and the turning over of the shovel plate is completed.

[0041] Preferably, when the turner assembly 2 is in the first position, the angle between the first support part 21 and the vertical line of the bottom end of the turner assembly 2 is 10°-30°, and the angle between the second support part 22 and the vertical line of the bottom end of the turner assembly 2 is -20°--40°. When the turner assembly 2 is in the second position, the angle between the first support part 21 and the vertical line of the bottom end of the turner assembly 2 is -10°--30°, and the angle between the second support part 22 and the vertical line of the bottom end of the turner assembly 2 is -50°--70°. In other embodiments of the utility model, as long as the first support part 21 and the second support part 22 are inclinedly arranged, and the shovel plate can rotate synchronously by itself when the turner assembly 2 drives the shovel plate to rotate, the utility model can be implemented.

[0042] The turnover assembly 2 is provided with a counterweight assembly 6 which is configured to reset the turnover assembly 2 to the first position after the spade plate is removed from the turnover assembly 2, specifically, the counterweight assembly 6 is connected to the rotating shaft 4, when the spade plate slides along the first support part 21 to the bottom end of the turnover assembly 2, the gravity of the spade plate and the turnover assembly 2 overcomes the gravity of the counterweight assembly 6, so that the turnover assembly 2 rotates relative to the support frame 1, the turnover assembly 2 rotates from the first position to the second position, and the counterweight assembly 6 is wound up and slides upwardly from the rotating shaft 4, after the spade plate which is turned over is separated from the turnover assembly 2, the counterweight assembly 6 overcomes the gravity of the turnover assembly 2, the counterweight assembly 6 drives the rotating shaft 4 to rotate and reset, and the counterweight assembly 6 slides downwardly to reset, so that the turnover assembly 2 rotates and resets, the turnover assembly 2 rotates from the second position to the first position, specifically, the counterweight assembly 6 comprises a counterweight block 61, the counterweight block 61 is connected to a pull rope 62, one end of the pull rope 62 which is away from the counterweight block 61 is tied to the rotating shaft 4.

[0043] The first support part 21 and the second support part 22 are provided with a limiting assembly 3, when the spade plate slides to the turnover assembly 2, the limiting assembly 3 abuts against the spade plate, through the limiting assembly 3, the position of the spade plate which slides along the first support part 21 is fixed, and the position of the spade plate which is turned over is also fixed, so that when the mechanical hand clamps, the mechanical hand does not need to position the spade plate, and only needs to set the inherent program of the mechanical hand.

[0044] Preferably, the limiting assembly 3 comprises a first limiting rod 31 which is fixedly connected to the first support part 21 and the second support part 22, when the spade plate slides to the turnover assembly 2, the first limiting rod 31 abuts against the spade head of the spade plate, the limiting assembly 3 comprises a second limiting rod 32 which is fixedly connected to the first support part 21 and the second support part 22, when the spade plate slides to the turnover assembly 2, the second limiting rod 32 abuts against the spade neck of the spade plate, in other embodiments of the utility model, only the first limiting rod 31 or the second limiting rod 32 can be arranged, or other limiting rods can be additionally arranged, as long as the spade plate can be limited.

[0045] Further, the turnover assembly 2 further comprises a base frame 23 which is fixedly connected to the first support part 21 and the second support part 22, when the spade plate slides along the first support part 21 to the base frame 23, the turnover assembly 2 rotates relative to the support frame 1, specifically, the base frame 23 can be selected from a triangular steel, one end of the triangular steel is connected to the first support part 21, and the other end of the triangular steel is connected to the second support part 22, in other embodiments of the utility model, the base frame 23 can also be selected from other materials.

[0046] Preferably, the chassis 23 is inclined, and the chassis 23 is inclined downward at an angle with the horizontal line, and the limiting assembly 3 is arranged at one end of the chassis 23 inclined downward, so that the spade plate falling onto the chassis 23 slides to the limiting assembly 3 until the limiting assembly 3 abuts against the spade plate, thereby ensuring that the spade plate affected by the inclination of the chassis 23 can slide to abut against the limiting assembly 3.

[0047] The rotating shaft 4 is connected to the turnover assembly 2, and the rotating shaft 4 is rotatably connected to the support frame 1, so that the turnover assembly 2 rotates with the rotating shaft 4 as the center. Preferably, the rotating shaft 4 is rotatably connected to the support frame 1 through the bearing 41.

[0048] Further, the support rod 11 is fixedly connected to the support frame 1, and the limiting frame 5 is fixedly connected to the rotating shaft 4, and the limiting frame 5 is sleeved on the support rod 11 and abuts against the support rod 11, thereby limiting the rotation angle of the turnover assembly 2. Specifically, the limiting frame 5 includes the first rod body 51, the second rod body 52, and the third rod body 53. The first rod body 51 and the second rod body 52 are fixedly connected to the rotating shaft 4, and the ends of the first rod body 51 and the second rod body 52 away from the rotating shaft 4 are fixedly connected to the third rod body 53. The support rod 11 is located between the first rod body 51 and the second rod body 52. After the turnover assembly 2 and the spade plate are rotated and turned over, the second rod body 52 abuts against the support rod 11. After the turnover assembly 2 is reset, the first rod body 51 abuts against the support rod 11. When the turnover assembly 2 is in the original position, the turnover assembly 2 is affected by the tension of the counterweight assembly 6, so that the first rod body 51 tightly abuts against the side wall of the support rod 11, thereby preventing the turnover assembly 2 from rotating in the reverse direction. When the spade plate slides to the bottom end of the turnover assembly 2, the gravity of the turnover assembly 2 and the spade plate overcomes the gravity of the counterweight assembly 6, so that the turnover assembly 2 and the spade plate rotate, the limiting frame 5 synchronously rotates, the second rod body 52 moves close to the support rod 11, and the first rod body 51 gradually separates from the support rod 11. When the second rod body 52 contacts the support rod 11, the movement is forcibly stopped.

[0049] The rotation angle of the turnover assembly 2 is the same as the angle between the first support rod 11 and the second support rod 11.

[0050] After the heating is completed, the spade plate is automatically and quickly turned over without the need of the mechanical hand to turn over, thereby saving time, ensuring the temperature of the spade plate during heat treatment, and ensuring the quality of the spade plate after heat treatment. Moreover, the mechanical hand does not need to be provided with a turnover program, and the mechanical hand only needs a simple grabbing program, thereby simplifying the structure.

[0051] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. For those skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and also impossible to exhaust all the implementation modes. Any modification, equivalent replacement and improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application claims.
