[0035] That is, a regulating device for the ear - picking plates 200 provided by the present utility model drives a transmission rod group 300 by a driving component 400 to drive the ear - picking plates 200 to move along a first direction, thereby realizing the automatic adjustment of the gaps between the ear - picking plates 200, solving the technical problem in the prior art that the gaps between the ear - picking plates 200 need to be manually adjusted, improving the adjustment efficiency of the gaps between the ear - picking plates 200, and reducing the labor intensity of users.

[0036] Specifically, the mounting frame 100 is made of sheet metal of a metallic material, and the ear - picking plates 200 are arranged as metallic flat plates. In this embodiment, the first direction is Figure 1 the X direction in. The mounting frames 100 are arranged at uniform intervals along the first direction. Each mounting frame 100 is provided with an ear - picking plate 200. The transmission rod group 300 is in transmission connection with the ear - picking plate 200 and drives the ear - picking plate 200 to move on the mounting frame 100. Furthermore, by adjusting the position of the ear - picking plate 200 on the mounting frame 100, since the mounting frame 100 is fixed, when the ear - picking plate 200 moves relative to the mounting frame 100, the distance between the ear - picking plate 200 and the adjacent mounting frame 100 is changed, realizing the adjustment of the ear - picking gap.

[0037] Furthermore, the regulating device for the ear - picking plates 200 further includes a baffle 500. The baffle 500 is arranged above the mounting frame 100. The baffle 500 is spaced from the mounting frame 100 to enclose a sliding gap, and the ear - picking plate 200 is slidably arranged in the sliding gap.

[0038] Specifically, the baffle 500 is arranged above the mounting frame 100 and is connected to the mounting frame 100 by bolts. A cushion block is arranged on the connecting bolts, so that the baffle 500 is spaced from the mounting frame 100. The ear - picking plate 200 is installed in the sliding gap enclosed by the baffle 500 and the mounting frame 100. Thus, the baffle 500 can be used to limit the ear - picking plate 200 to slide only along the first direction.

[0039] Furthermore, the transmission rod group 300 includes a rotating rod 310 and a swing rod 320. The rotating rod 310 is rotatably arranged on the mounting frame 100 along a second direction. The swing rod 320 is fixed to the swing rod 320 along a direction perpendicular to the extension direction of the swing rod 320. The swing rod 320 is in transmission connection with the ear - picking plate 200, and the second direction is perpendicular to the first direction.

[0040] Specifically, the second direction is Figure 1 the Y direction in. A square groove is arranged on the mounting frame 100. The rotating rod 310 is arranged in the groove. Bearings can be arranged at both ends of the groove to install the rotating rod 310 and enable the rotating rod 310 to rotate around its own axis. One end of the swing rod 320 is perpendicularly welded to the swing rod 320, so as to swing along with the rotation of the rotating rod 310. The other end of the swing rod 320 is connected to the ear - picking plate 200, thereby driving the ear - picking plate 200 to move.

[0041] Preferably, a sliding rod 210 is provided on the ear stripper plate 200, and a sliding groove 321 is provided on the swing rod 320, and the sliding rod 210 is slidably arranged in the sliding groove 321.

[0042] Specifically, the sliding rod 210 is fixed to the bottom of the ear stripper plate 200 by welding, and a sliding groove 321 is provided on the swing rod 320. When the swing rod 320 rotates, the sliding rod 210 will slide in the sliding groove 321, so that the ear stripper plate 200 slides along the first direction.

[0043] Further, the ear stripper plate 200 extends along the second direction on the mounting frame 100, a plurality of swing rods 320 are arranged at intervals along the second direction on the rotating rod 310, and the ear stripper plate 200 is provided with sliding rods 210 arranged in one-to-one correspondence with the swing rods 320.

[0044] Specifically, in this embodiment, in order to ensure that the ear stripper plate 200 can move stably along the first direction, the ear stripper plate 200 extends along the second direction on the mounting frame 100 and two sliding rods 210 are provided on the ear stripper plate 200. Correspondingly, two swing rods 320 are arranged at intervals along the second direction on the rotating rod 310. Thus, they jointly drive the ear stripper plate 200 to move along the first direction, improving the stability of the movement of the ear stripper plate 200.

[0045] Further, the transmission rod group 300 further includes a connecting rod 330 and a transmission cross bar 340. The transmission cross bar 340 is arranged below the mounting frame 100 along the first direction, and the driving assembly 400 is connected to the transmission cross bar 340 to drive the transmission cross bar 340 to move along the first direction. One end of the connecting rod 330 is connected to the transmission cross bar 340, the other end of the connecting rod 330 is connected to the rotating rod 310, and a number of connecting rods 330 are arranged in one-to-one correspondence with the mounting frame 100.

[0046] Specifically, the transmission cross bar 340 is arranged below the mounting frame 100 along the first direction and is connected to the driving assembly 400. The driving assembly 400 can drive it to move along the first direction. A connecting rod 330 is provided on each mounting frame 100. One end of the connecting rod 330 is provided with a long slot hole, and a bolt on the transmission cross bar 340 extends into the long slot hole to be connected to the connecting rod 330. By the sliding of the bolt in the long slot hole, it can be ensured that when the transmission cross bar 340 moves along the first direction, it can drive the connecting rod 330 to rotate. The other end of the connecting rod 330 is welded to the rotating rod 310, thereby driving the rotating rod 310 to rotate. Thus, it also realizes driving all the ear stripper plates 200 to move simultaneously through the transmission cross bar 340, so as to improve the adjustment efficiency of the ear stripping gap.

[0047] Further, the driving assembly 400 includes a hydraulic oil tank, a hydraulic pipeline 410 and an oil cylinder 420. The two ends of the hydraulic pipeline 410 are respectively connected to the hydraulic oil tank and the oil cylinder 420, and the output end of the oil cylinder 420 is connected to the transmission cross bar 340.

[0048] Specifically, both ends of the hydraulic pipeline 410 are respectively connected to the hydraulic oil tank and the oil cylinder 420. The oil cylinder 420 is arranged along the first direction, and the push rod of the oil cylinder 420 is connected to the transmission cross bar 340, so as to drive the transmission cross bar 340 to move along the first direction. The hydraulic oil tank can control the oil cylinder 420 through the valve assembly, and further drive the transmission cross bar 340, the connecting rod 330, the rotating rod 310 and the swing rod 320, so as to drive the ear picking plate 200 to move, and realize the automatic adjustment of the ear picking gap of the ear picking plate 200.
