[0007] As a further solution of the utility model, the output shaft of the first motor is fixedly installed between the fixed plate, the output shaft of the second motor passes through the inside of the fixed plate and is fixedly connected to the cam, and the four first slide seats are installed in a ring shape.

[0008] As a further solution of the utility model, the first slide seat is slidably arranged on the top of the fixed plate through the first guide rail, and the two ends of the first tension spring are respectively connected to the fixed plate and the first slide seat.

[0009] As a further solution of the utility model, the second slide seat is sleeved on the outside of the second guide rail and is slidably arranged, and the two ends of the second tension spring are respectively connected to the fixed plate and the second slide seat.

[0010] As a further solution of the utility model, a buffer mechanism is installed on the outer side of the four second slide seats, and the buffer mechanism includes four swing arm bodies, and the four swing arm bodies are respectively fixedly installed on the outer sides of the four second slide seats, a third guide rail is installed on the top of the swing arm body, a fixed seat is movably installed on the top of the third guide rail, a suction nozzle is installed on the outer end of the fixed seat, a limiting column is installed on the inner side of the third guide rail near the outer end, an adjusting stud is movably installed on the inner side of the third guide rail near the inner end, a locking stud is installed on the inner end of the adjusting stud, and a buffer spring is installed between the adjusting stud and the fixed seat and inside the third guide rail.

[0011] As a further solution of the utility model, the fixing seat is located at the top of the third guide rail and is slidably arranged, and the limiting column is located inside the third guide rail and is fixedly installed.

After the grains are adsorbed, there is sufficient safety space for rotation, which greatly improves the compatibility of products of different specifications and sizes.

[0015] By setting up four swing arms, the problem of the nozzle on one side sucking the grains during the process of picking and placing the grains can be solved. The nozzle at the 90° position can be used for detection, and the nozzle at the 180° position can be used to place the grains after detection. An additional detection station is added during the picking and placing process, and one more station is used for detection, which enriches the functionality of the equipment and improves the overall efficiency of grain picking, detection, and placing.

[0016] By setting a buffer mechanism, the nozzle contacts the product so that the fixed seat slides through the third guide rail. The nozzle is buffered in the straight direction by the expansion and contraction of the buffer spring. During the process of picking and placing the grain, the grain adsorption has a higher degree of parallelism with the plane of the nozzle, and the stability of picking and placing the grain is better. Each nozzle provides independent buffering, which is compatible with the production of thick chips.

[0017] By setting an adjusting stud and rotating the locking stud to make the adjusting stud slide under the action of the thread, the compression amount of the buffer spring is changed, and the buffer force of the suction nozzle is adjustable. Different buffer forces can be adjusted for different shovels to meet the requirements of grain picking and placing. The buffer force of each suction nozzle can be adjusted individually, and the grain will not be crushed when picking and placing the grain. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In this embodiment, the output shaft of the first motor 2 is fixedly installed between the fixed plate 1, the output shaft of the second motor 7 passes through the inside of the fixed plate 1 and is fixedly connected to the cam 11, and the four first slide seats 6 are installed in a ring shape. The fixed plate 1 is driven to rotate by the first motor 2 to provide power for the rotation of the four suction nozzles 21 and the four swing arm bodies 18.

[0028] In this embodiment, the first slide 6 is slidably arranged on the top of the fixed plate 1 through the first guide rail 9, and the two ends of the first tension spring 10 are respectively connected to the fixed plate 1 and the first slide 6. The first tension spring 10 pulls the first slide 6 inward to provide force for the first follower 12 to fit closely with the cam 11.

[0029] In this embodiment, the second slide 8 is sleeved on the outside of the second guide rail 14 and is slidably arranged. The two ends of the second tension spring 17 are respectively connected to the fixed plate 1 and the second slide 8. The second tension spring 17 pulls the second slide 8 inward so that the swing arm body 18 is close to the second follower 13.

After they are in place, the cam 11 is driven to rotate by the second motor 7. Under the action of the cam 11, the first follower 12 is pushed to make the first slide 6 and the second slide 8 drive the swing arm body 18 and the suction nozzle part 21 to move forward. When the suction nozzle part 21 moves forward, under the guided sliding action of the third guide rail 19, the product is pressed with a certain contact force and adsorbed at the same time. The flow meter 16 is used to detect whether the product is sucked. After the product is sucked, the first motor 2 rotates in the opposite direction, and under the action of the first tension spring 10 and the second tension spring 17, the swing arm body 18 retreats. After they are in place, the first motor 2 rotates 90° to make the next suction nozzle part 21 take the material, and at the same time, the swing arm body 18 and the suction nozzle part 21 at the 180° position on the opposite side perform the material discharge action forward and backward.
