[0023] As Figures 1 to 3As shown, the vegetable jar flipping and clamping device comprises a frame 1, both ends of the frame 1 are provided with clamping arms 2 slidingly in the horizontal direction, a clamping driving component 7 for driving the clamping arms 2 to reciprocate is provided inside the frame 1, a clamping claw assembly 3 is rotatably provided at the end of the clamping arm 2, and a flipping driving mechanism for driving the clamping claw assembly 3 to flip outward or reset is provided on the clamping arm 2. When in use, the frame 1 is usually installed on a forklift, and the clamping driving component 7 can drive the two clamping arms 2 to drive the two clamping claw assemblies 3 to approach each other to clamp the vegetable jar, and the forklift drives the vegetable jar to be lifted to a certain height at the same time, and then the flipping driving mechanism drives the clamping claw assembly 3 to flip outward, and the pickled vegetables in the vegetable jar are poured out, thereby improving the efficiency of taking out vegetables and reducing labor expenses; the clamping claw assembly 3 has a supporting plate 39, an upper clamping plate 31 and a lower clamping plate 32, the supporting plate 39 is rotatably provided at one end of the clamping arm 2, and two clamping claw assemblies are symmetrically provided on the side of the supporting plate 39 away from the clamping arm 2. The front swing arm 34 and the two rear swing arms 33 are staggered front and back, and the middle parts of the front swing arm 34 and the rear swing arm 33 are rotatably connected to the support plate 39. The upper clamping plate 31 is hinged to the upper ends of the front swing arm 34 and the rear swing arm 33, and the lower clamping plate 32 is hinged to the lower ends of the front swing arm 34 and the rear swing arm 33. An angle adjustment mechanism for adjusting the angles of the front swing arm 34 and the rear swing arm 33 is provided on the support plate 39; in the present embodiment, the angles of the front swing arm 34 and the rear swing arm 33 are adjusted by the angle adjustment mechanism, and the positions of the upper clamping plate 31 and the lower clamping plate 32 in the horizontal direction can be adjusted in the opposite direction at the same time, so that the positions of the upper clamping plate 31 and the lower clamping plate 32 correspond to the upper and lower positions of the vegetable jar respectively. When using vegetable jars of different specifications, the upper clamping plate 31 and the lower clamping plate 32 can be adjusted to be tightly attached to the upper and lower parts of the vegetable jar at the same time, respectively, to ensure the stability of clamping and fixing the vegetable jar.

[0024] In some embodiments, the angle adjustment mechanism has a double-rod hydraulic cylinder 35 fixedly arranged on the side of the support plate 39, and the two ends of the double-rod hydraulic cylinder 35 are respectively connected to the upper clamping plate 31 and the lower clamping plate 32 for transmission; piston rods are arranged on both sides of the piston in the double-rod hydraulic cylinder 35. When the piston moves under hydraulic drive, one piston rod is retracted into the piston cylinder, and the other piston rod extends outward from the piston cylinder, and the movement speed of the two piston rods is the same; when the piston of the double-rod hydraulic cylinder 35 moves, the two piston rods at its two ends are respectively transmitted between the upper clamping plate 31 and the lower clamping plate 32, thereby driving the upper clamping plate 31 and the lower clamping plate 32 to move, and the upper clamping plate 31 and the lower clamping plate 32 drive the front swing arm 34 and the rear swing arm 33 to swing, thereby realizing the adjustment of the angles of the front swing arm 34 and the rear swing arm 33.

[0025] In some embodiments, chains 36 are connected to both ends of the double-rod hydraulic cylinder 35, and the ends of the two chains 36 facing away from the double-rod hydraulic cylinder 35 are respectively connected to the upper clamping plate 31 and the lower clamping plate 32; when the piston in the double-rod hydraulic cylinder 35 moves upward, the piston rod at the lower end of the double-rod hydraulic cylinder 35 moves upward and pulls the lower clamping plate 32 to move toward the side close to the clamping arm 2 through the chain 36, and the piston rod at the upper end of the double-rod hydraulic cylinder 35 moves upward to release the chain 36. During the movement of the lower clamping plate 32, the front swing arm 34 and the rear swing arm 33 are driven to swing. When the front swing arm 34 and the rear swing arm 33 swing, the upper clamping plate 31 is driven to move toward the side away from the clamping arm 2, so that the horizontal positions of the upper clamping plate 31 and the lower clamping plate 32 can be adjusted in opposite directions at the same time; when the piston in the double-rod hydraulic cylinder 35 moves downward, the principle is similar to the above and will not be repeated.

[0026] In some embodiments, a sprocket 38 cooperating with the chain 36 is disposed on the side of the support plate 39 , and the sprocket 38 is rotatably disposed on the side of the support plate 39 via an axle seat 37 .

[0027] In some embodiments, the flipping drive mechanism has a flipping drive component 6 arranged above the clamping arm 2, one end of the flipping drive component 6 is hinged to the clamping arm 2, and the other end of the flipping drive component 6 is hinged to a transmission plate 4, the middle part of the transmission plate 4 is hinged to the clamping arm 2, and the end of the transmission plate 4 facing away from the flipping drive component 6 is connected to the outer side of the support plate 39 through a connecting rod 5, one end of the connecting rod 5 is rotatably connected to the support plate 39, and the other end of the connecting rod 5 is rotatably connected to the transmission plate 4; when the flipping drive component 6 is extended, it pushes the transmission plate 4 to rotate, and the transmission plate 4 drives the clamping jaw assembly 3 to flip outward through the connecting rod 5; when the flipping drive component 6 is retracted, it pulls the transmission plate 4 to reset, and the transmission plate 4 drives the clamping jaw assembly 3 to flip inward and reset through the connecting rod 5.

[0028] In some embodiments, the flipping driving component 6 and the clamping driving component 7 are any one of a hydraulic cylinder, a pneumatic cylinder, and an electric cylinder.

[0029] In some embodiments, upper clamping blocks 311 corresponding to the vegetable jar are provided at both ends of the upper clamping plate 31; lower clamping blocks 321 corresponding to the vegetable jar are provided at both ends of the lower clamping plate 32. The upper clamping blocks 311 and the lower clamping blocks 321 are made of elastic materials such as polyurethane and rubber, which can play a buffering role when clamping to avoid damage to the vegetable jar.

[0030] In some embodiments, the upper clamping plate 31 and the lower clamping plate 32 are both “C”-shaped plate structures.

[0031] In some embodiments, Figure 4As shown, the double-rod hydraulic cylinder 35 is connected to a two-way pump 351. Between the two-way pump 351 and the double-rod hydraulic cylinder 35, there is an adjusting solenoid valve 352 used to connect or cut off the communication between the rod chamber and the non-rod chamber of the double-rod hydraulic cylinder 35. The angle adjustment of the jaw assembly 3 has two modes. One is the automatic adaptive adjustment mode used during normal operation, and the other is the manual adaptive adjustment mode used during debugging, fault detection, or other situations requiring manual intervention. In the automatic adaptive adjustment mode, the two-way pump 351 does not work and is not involved in the automatic adjustment action. The method to achieve automatic adaptive adjustment is to control the adjusting solenoid valve 352 to connect the rod chamber and the non-rod chamber of the double-rod hydraulic cylinder 35. At this time, the piston rod of the double-rod hydraulic cylinder 35 can move freely under the action of external forces. Then, control the two jaw assemblies 3 to approach the pickling jar and abut against it. The pickling jar pushes the upper clamping plate 31 and the lower clamping plate 32 to move to a suitable position, so that the upper clamping plate 31 and the lower clamping plate 32 are evenly attached to and clamped by the pickling jar to achieve automatic adjustment. When the clamping action is completed, the adjusting solenoid valve 352 loses power, and the communication between the rod chamber and the non-rod chamber of the double-rod hydraulic cylinder 35 is cut off. The position of the double-rod hydraulic cylinder 35 is locked. At this time, the positions of the upper clamping plate 31 and the lower clamping plate 32 are also locked at the adjusted positions. In the manual adaptive adjustment mode, the adjusting solenoid valve 352 loses power, and the communication between the rod chamber and the non-rod chamber of the double-rod hydraulic cylinder 35 is cut off. At this time, control the two-way pump 351 to start and provide pressure oil for the double-rod hydraulic cylinder 35 in the corresponding direction to drive the double-rod hydraulic cylinder 35 to move in the corresponding direction. The double-rod hydraulic cylinder 35 then drives the upper clamping plate 31 and the lower clamping plate 32 to adjust their positions through a chain.

To avoid obscuring the concept of the present invention, some details well known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed here based on the above description.

[0033] The above-described embodiments only represent some implementation manners of the present invention. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
