[0016] S2: operating the vertical position adjustment member to swing the third mounting seat relative to the positioning frame, so as to adjust the inclination angle of the feeder body;

[0017] S3: during the process of adjusting the vertical displacement of the feeder body, the force support member loses support for the feeder body, and after the adjustment is completed, the force support member is operated to support the feeder body;

[0018] S4: Then, the object is placed on the feeder body. When the object is transported through the operation of the feeder body, part of the gravity of the object and the feeder body will act on the force support member.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. By setting a vertical swing adjustment member, the telescopic cylinder is started, and the fifth transmission bevel gear is meshed with the first transmission bevel gear through the extension of the telescopic cylinder. The operation of the motor causes the movable sleeve connecting frame limited by the positioning guide frame to move upward or downward along the first transmission bevel gear, so that the positioning frame drives the feeder body to adjust the vertical displacement through the third mounting seat. Similarly, the fifth transmission bevel gear at one end of the rotating connecting sleeve rod away from the first transmission bevel gear is meshed with the second transmission bevel gear through the contraction of the telescopic cylinder, so that the vertical height of the two ends of the feeder body is adjusted when the motor rotates, thereby increasing the adjustment range and further increasing the applicable range of the feeder body;

[0021] 2. By setting a force-sharing support, when the feeder body moves relative to the base, the piston rod moves relative to the piston cylinder. At this time, the aqueous solution inside the piston cylinder will enter the liquid storage tank through the connecting pipe and the transition connecting chamber under the push of the piston rod, or the aqueous solution inside the liquid storage tank will enter the piston cylinder through the transition connecting chamber and the connecting pipe under the extraction of the piston rod. After the feeder body is adjusted, the adjusting screw is rotated. The blocking block is moved downward by rotating the adjusting screw, so that the bottom of the blocking block fits with the bottom of the inner wall of the transition connecting chamber, so that the blocking block blocks the port of the connecting pipe. In this way, the aqueous solution inside the piston cylinder can support the piston rod, thereby improving the stability of the feeder body after adjustment, and also preventing the pressure on the feeder body from acting entirely on the connection between the third mounting seat and the positioning frame, further increasing the service life of the equipment;

[0022] 3. By setting a contact control component, when the main body of the feeder is adjusted, the blocking plug loses its barrier to the aqueous solution inside the liquid storage tank, and the movable contact piece contacts the first fixed contact piece, while the main body of the feeder is in a power-off state. After the adjustment of the main body of the feeder is completed, the blocking plug is used to block the aqueous solution inside the liquid storage tank by rotating the adjusting screw rod, and the guide rod moves down synchronously with the blocking plug. At this time, the movable contact piece is separated from the first fixed contact piece, and the movable contact piece contacts the second fixed contact piece, so that the main body of the feeder can be powered on to operate, thereby preventing the force support member from using the main body of the feeder when the main body of the feeder is not supported.

[0035] In this embodiment: after the base 1 is moved to the specified position, the vertical positioning adjustment member is operated to make the movable sleeve connecting frame 418 move vertically relative to the positioning guide frame 407, so that the loader body 2 can be moved vertically relative to the base 1, so as to adjust the vertical height of the loader body 2. At the same time, the vertical positioning adjustment member can be operated to make the third mounting seat 409 swing relative to the positioning frame 410, so as to adjust the inclination angle of the loader body 2, thereby improving the application range of the loader body 2. During the vertical displacement adjustment process of the loader body 2, the force support member loses its support for the loader body 2. After the adjustment is completed, the force support member is operated to support the loader body 2. When the loader body 2 transports objects, part of the gravity of the objects and the loader body 2 will act on the force support member.

[0036] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4The vertical position adjustment member includes a transposition gear 412 mounted on the inner side of the third mounting seat 409. The top of the base 1 is rotatably connected to a first reciprocating screw 408 located on the inner side of the positioning guide frame 407 through a bearing. The bottom of the movable sleeve connecting frame 418 is movably sleeved on the first reciprocating screw 408. The inner side of the positioning frame 410 is rotatably connected to a second reciprocating screw 417 through a bearing. The second reciprocating screw 417 is movably sleeved with a shifting rack meshing with the transposition gear 412. 416, a fourth transmission bevel gear 422 located outside the positioning frame 410 is installed at one end of the second reciprocating screw rod 417, a third transmission bevel gear 421 meshing with the fourth transmission bevel gear 422 is installed on the outer wall of the positioning frame 410, a hexagonal telescopic rod 411 connected to the base 1 is provided at the bottom of the third transmission bevel gear 421, a first transmission bevel gear 419 located below the base 1 is installed at the bottom of the first reciprocating screw rod 408, and the bottom of the hexagonal telescopic rod 411 A second transmission bevel gear 420 is installed below the base 1, a U-shaped fixed frame 404 is installed at the bottom of the base 1, a motor 406 is installed on one side of the U-shaped fixed frame 404, the output end of the motor 406 is connected to a hexagonal rotating rod 429 located inside the U-shaped fixed frame 404, a rotating sleeve rod 424 is movably sleeved on the hexagonal rotating rod 429, and a fifth transmission bevel gear 423 is installed at both ends of the rotating sleeve rod 424, and the outer side of the rotating sleeve rod 424 is rotatably connected to a sliding connecting block through a bearing. 426, a guide groove 428 is provided at the bottom of the U-shaped fixed frame 404, and the sliding connecting block 426 is slidably connected to the inner side of the guide groove 428. A telescopic cylinder 405 is installed on the side of the U-shaped fixed frame 404 away from the motor 406. The output end of the telescopic cylinder 405 is connected to a compensation rod 425 extending to the inner side of the U-shaped fixed frame 404. Both sides of the sliding connecting block 426 are movably sleeved on the compensation rod 425, and a compensation spring 427 connected to the sliding connecting block 426 is provided on the compensation rod 425.

[0037] In this embodiment, when the vertical displacement of the feeder body 2 is adjusted, the telescopic cylinder 405 is first started, and the compensation rod 425 is moved horizontally by the extension of the telescopic cylinder 405. When the compensation rod 425 moves, the compensation spring 427 and the sliding block 426 drive the rotating sleeve rod 424 to move, so that the rotating sleeve rod 424 moves toward the first transmission bevel gear 419, so that the fifth transmission bevel gear 423 at one end of the rotating sleeve rod 424 meshes with the first transmission bevel gear 419. At this time, the motor 406 is started, and the hexagonal rotating rod 429 drives the rotating sleeve rod 424 to rotate through the operation of the motor 406, so that the rotating sleeve rod 424 drives the first reciprocating screw rod 408 to rotate through the fifth transmission bevel gear 423 and the first transmission bevel gear 419. When the first reciprocating screw rod 408 rotates, the movable sleeve frame 418 limited by the positioning guide frame 407 can be moved along the first transmission bevel gear 419. A transmission bevel gear 419 moves upward or downward, so that the positioning frame 410 drives the loading machine body 2 to adjust the vertical displacement through the third mounting seat 409. Similarly, the fifth transmission bevel gear 423 at one end of the rotating connecting rod 424 is away from the first transmission bevel gear 419 through the contraction of the telescopic cylinder 405, and the second transmission bevel gear 420 is meshed with the second transmission bevel gear 420, so that when the motor 406 rotates, the second transmission bevel gear 420 drives the second reciprocating screw rod 417 to rotate through the hexagonal telescopic rod 411, the third transmission bevel gear 421, and the fourth transmission bevel gear 422. At this time, the shifting rack 416 will move along the second reciprocating screw rod 417, and the third mounting seat 409 is rotated relative to the positioning frame 410 by shifting the shifting gear 412. In this way, the vertical heights of the two ends of the loading machine body 2 can be adjusted, thereby increasing the adjustment range and further increasing the applicable range of the loading machine body 2.

[0038] Please refer to Figure 4 The fifth transmission bevel gears 423 at both ends of the rotating connecting rod 424 are symmetrically arranged along the vertical center axis of the rotating connecting rod 424. The maximum extension length of the telescopic cylinder 405 is half of the distance from the second transmission bevel gear 420 to the first transmission bevel gear 419. Through holes that match the compensation rod 425 are arranged on both sides of the sliding connecting block 426.

[0039] In this embodiment: by setting this structure, when the telescopic cylinder 405 is fully extended or retracted, the first transmission bevel gear 419 is meshed with the fifth transmission bevel gear 423 or the second transmission bevel gear 420 is meshed with the fifth transmission bevel gear 423. At the same time, the sliding connecting block 426 of the compensation spring 427 is used to reserve a movable space on the compensation rod 425 to prevent the fifth transmission bevel gear 423 from colliding with the first transmission bevel gear 419 or the second transmission bevel gear 420 when it contacts the first transmission bevel gear 419 or the second transmission bevel gear 420. When the latching teeth on 23 come into contact with the latching teeth on the first transmission bevel gear 419, the compensation spring 427 will extend as the telescopic cylinder 405 extends. At this time, the fifth transmission bevel gear 423 will have the force to move toward the first transmission bevel gear 419. As the motor 406 rotates, the tooth groove on the fifth transmission bevel gear 423 rotates to the position where the latching teeth on the first transmission bevel gear 419 mesh with each other, and the fifth transmission bevel gear 423 meshes with the first transmission bevel gear 419 under the action of the elastic restoring force of the compensation spring 427.

[0040] Please refer to Figure 3 A crescent pin matching the outer side of the second reciprocating screw rod 417 is provided on the inner side of the shifting rack 416 , and both sides of the shifting rack 416 are slidably connected to the inner side of the locking frame 410 .

[0041] In this embodiment: by setting this structure, when the second reciprocating screw 417 rotates, the shift rack 416 moves back and forth along the second reciprocating screw 417. Similarly, the movable sleeve connecting frame 418 moves back and forth in the vertical direction along the first reciprocating screw 408. The adjustment of different positions of the loading machine body 2 can be achieved without controlling the forward and reverse rotation of the motor 406.

[0042] Please refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 8The force support member includes a first mounting seat 3 installed at the bottom of both ends of the feeder body 2, the bottom of the first mounting seat 3 is rotatably connected to a piston rod 401 through a rotating shaft, the top of the base 1 is installed with a second mounting seat 403 located on both sides of the positioning guide frame 407, the top of the second mounting seat 403 is rotatably connected to a piston cylinder 402 through a rotating shaft, the piston cylinder 402 is sleeved on the outside of the piston rod 401, and a connecting pipe 413 is installed at the bottom end of the piston cylinder 402, and a liquid storage tank 415 is provided on the top of the base 1, and a transition connecting chamber 4 is installed on the outer wall of the liquid storage tank 415 through the connecting pipe 413. 30. Both sides of the transition connecting chamber 430 are connected to the piston cylinder 402 through the connecting pipe 413. The top of the transition connecting chamber 430 is connected with an adjusting screw 432 extending to the inside of the transition connecting chamber 430. The bottom end of the adjusting screw 432 is installed with a blocking block 414 located on the inner side of the transition connecting chamber 430. The blocking block 414 is in contact with the inner wall of the transition connecting chamber 430 on all sides. A liquid pushing piston 434 is inserted into the inside of the liquid storage tank 415. A return spring 433 connected to the top of the liquid storage tank 415 is arranged on the liquid pushing piston 434. A touch control member is arranged on the top of the adjusting screw 432.

[0043] In this embodiment, when the feeder body 2 moves relative to the base 1, the piston rod 401 moves relative to the piston cylinder 402. At this time, the aqueous solution inside the piston cylinder 402 will enter the liquid storage tank 415 through the connecting pipe 413 and the transition connecting chamber 430 under the push of the piston rod 401, or the aqueous solution inside the liquid storage tank 415 will enter the piston cylinder 402 through the transition connecting chamber 430 and the connecting pipe 413 under the extraction of the piston rod 401. After the feeder body 2 is adjusted, the adjusting screw 432 is rotated. By adjusting the screw 432 The rotation causes the blocking block 414 to move downward, so that the bottom of the blocking block 414 fits against the bottom of the inner wall of the transition chamber 430, so that the blocking block 414 blocks the port of the connecting pipe 413, so that the aqueous solution inside the piston cylinder 402 can support the piston rod 401, thereby improving the stability of the feeder body 2 after adjustment, and also preventing the pressure on the feeder body 2 from acting entirely on the connection between the third mounting seat 409 and the positioning frame 410, further increasing the service life of the equipment.

[0044] Please refer to Figure 8 A threaded hole matching the adjusting screw rod 432 is provided on the top of the transition connecting chamber 430 .

[0045] In this embodiment: by setting this structure, the adjusting screw rod 432 can move upward or downward along the transition chamber 430 when it rotates, and at the same time prevent the water flow from pushing the blocking block 414 to cause the adjusting screw rod 432 to move vertically.

[0046] Please refer to Figure 1 , Figure 5 , Figure 7 , Figure 8 The contact control component includes a positioning frame 431 installed on the outer side of the top of the transition connecting chamber 430, a control chamber 435 is installed on the top of the positioning frame 431, the top of the adjusting screw rod 432 is rotatably connected to a guide plug rod 436 extending to the inner side of the control chamber 435 through a bearing, a second fixed contact piece 439 located on the inner side of the control chamber 435 is provided on the top of the positioning frame 431, a movable contact piece 438 located above the second fixed contact piece 439 is installed on the top of the guide plug rod 436, and a first fixed contact piece 437 located above the movable contact piece 438 is installed on the top of the inner wall of the control chamber 435.

[0047] In this embodiment: when the feeder body 2 is adjusted, the blocking plug 414 loses its barrier to the aqueous solution inside the liquid storage tank 415, and the movable contact piece 438 contacts the first fixed contact piece 437, while the feeder body 2 is in a power-off state. After the adjustment of the feeder body 2 is completed, the blocking plug 414 blocks the aqueous solution inside the liquid storage tank 415 by rotating the adjusting screw 432, and the guide rod 436 moves downward synchronously with the blocking plug 414. At this time, the movable contact piece 438 is separated from the first fixed contact piece 437, and the movable contact piece 438 contacts the second fixed contact piece 439, so that the feeder body 2 can be powered on to operate, so as to prevent the force support from using the feeder body 2 when the feeder body 2 is not supported.

[0048] Please refer to Figure 8 The first fixed contact piece 437 is electrically connected to the motor 406 and the telescopic cylinder 405 through a wire, the second fixed contact piece 439 is electrically connected to the feeder body 2 through a wire, and the movable contact piece 438 is electrically connected to the external power supply through a wire.

[0049] In this embodiment: the operation timing of the telescopic cylinder 405, the motor 406, and the feeder body 2 is controlled by the contact between the movable contact piece 438 and the first fixed contact piece 437 and the second fixed contact piece 439.

[0050] Please refer to Figure 8 A through hole having a diameter greater than that of the guide rod 436 is formed on the inner side of the second fixed contact piece 439 .

[0051] In this embodiment, this structure is provided to prevent the guide rod 436 from rubbing against the second fixed contact piece 439 when moving up and down, thereby preventing the second fixed contact piece 439 from being worn.

[0052] In combination with the above-mentioned vertical displacement adjustment device, a vertical displacement adjustment method is provided below, which specifically includes the following steps:

[0053] S1: After the base 1 is moved to the specified position, the telescopic cylinder 405 is started, and the compensation rod 425 is moved horizontally by the extension of the telescopic cylinder 405. When the compensation rod 425 moves, the compensation spring 427 and the sliding block 426 drive the rotating sleeve rod 424 to move, so that the rotating sleeve rod 424 moves toward the first transmission bevel gear 419, so that the fifth transmission bevel gear 423 at one end of the rotating sleeve rod 424 is meshed with the first transmission bevel gear 419. At this time, the motor 406 is started, and the motor 4 06 is operated to make the hexagonal rotating rod 429 drive the rotating sleeve rod 424 to rotate, so that the rotating sleeve rod 424 drives the first reciprocating screw rod 408 to rotate through the fifth transmission bevel gear 423 and the first transmission bevel gear 419. When the first reciprocating screw rod 408 rotates, the movable sleeve connecting frame 418 limited by the positioning guide frame 407 can move upward or downward along the first transmission bevel gear 419, so that the positioning frame 410 drives the feeder body 2 to adjust the vertical displacement through the third mounting seat 409;

[0054] S2: The fifth transmission bevel gear 423 at one end of the rotating sleeve rod 424 away from the first transmission bevel gear 419 is meshed with the second transmission bevel gear 420 by contracting the telescopic cylinder 405, so that when the motor 406 rotates, the second transmission bevel gear 420 drives the second reciprocating screw rod 417 to rotate through the hexagonal telescopic rod 411, the third transmission bevel gear 421, and the fourth transmission bevel gear 422. At this time, the shift rack 416 will move along the second reciprocating screw rod 417, and the third mounting seat 409 will rotate relative to the positioning frame 410 by shifting the shift gear 412, so that the vertical heights of the two ends of the feeder body 2 can be adjusted, thereby increasing the adjustment range and further increasing the applicable range of the feeder body 2;

[0055] S3: When the feeder body 2 moves relative to the base 1, the piston rod 401 moves relative to the piston cylinder 402. At this time, the aqueous solution inside the piston cylinder 402 will enter the liquid storage tank 415 through the connecting pipe 413 and the transition connecting chamber 430 under the push of the piston rod 401, or the aqueous solution inside the liquid storage tank 415 will enter the piston cylinder 402 through the transition connecting chamber 430 and the connecting pipe 413 under the extraction of the piston rod 401. After the feeder body 2 is adjusted, the adjusting screw 432 is rotated. The movement causes the blocking block 414 to move downward, so that the bottom of the blocking block 414 fits with the bottom of the inner wall of the transition connecting chamber 430, so that the blocking block 414 blocks the port of the connecting pipe 413, so that the aqueous solution inside the piston cylinder 402 can support the piston rod 401, so as to improve the stability of the feeder body 2 after adjustment, and also prevent the pressure on the feeder body 2 from acting entirely on the connection between the third mounting seat 409 and the positioning frame 410, further increasing the service life of the equipment;

[0056] S4: After the adjustment of the feeder body 2 is completed, the blocking block 414 is used to block the aqueous solution inside the liquid storage tank 415 by rotating the adjusting screw 432, and the guide rod 436 is synchronously moved down with the blocking block 414. At this time, the movable contact piece 438 is separated from the first fixed contact piece 437, and the movable contact piece 438 is in contact with the second fixed contact piece 439, so that the feeder body 2 can be powered on to operate, so as to prevent the force support from using the feeder body 2 when it is not supporting the feeder body 2. Then, the object is placed on the feeder body 2, and the object is transported by the operation of the feeder body 2.
