[0022] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0023] See also Figures 1 to 4 A tooth-interval motion mechanism for preventing short packages of edible fungi includes a turntable 1 and a disc 2 located above the turntable 1. The turntable 1 and the disc 2 are concentrically arranged. The turntable 1 is driven to rotate by a driving mechanism, and the disc 2 is fixed.

[0024] The edge of the disk 2 is provided with a concave notch 21, and the two sides of the notch 21 are smoothly transitioned to the edge of the disk 2. A rack 22 is fixed to the bottom surface of the disk 2 below the notch 21, and the top of each tooth of the rack 22 is located on the extension line of the arc of the edge of the disk 2.

[0025] The rotating disk 1 is provided with a gear mechanism 3 rotating with the rotating disk 1 on the annular portion located outside the disk 2. The gear 31 of the gear mechanism 3 is rotatably connected to the rotating disk 1. The gear 31 can rotate relative to the rotating disk 1 and can mesh with the rack 22. A positioning plate 32 is fixed above the gear 31. At least two bearing members 33 are arranged on the positioning plate 32 at intervals, wherein the outer edges of the bearings 331 of the two bearing members 33 are close to the edge of the disk 2. The bearings 331 of the two bearing members 33 are close to the edge of the disk 2, so that the gear 31 is prevented from idling and causing dislocation when it is not meshed with the rack 22.

[0026] A retaining pressure block 41 is provided near the notch 21 on the disc 2, and the middle part of the retaining pressure block 41 is rotatably connected to the top surface of the disc 2 via a rotating shaft, and a limiting block 42 is fixed to the end of the retaining pressure block 41 close to the center of the disc 2 on the side opposite to the rotation direction of the turntable 1, and the end of the retaining pressure block 41 close to the center of the disc 2 is connected to the limiting block 42 via a tension spring 43, and the tension spring 43 provides a force to pull the end of the retaining pressure block 41 toward the limiting block 42. The outer edge of the other end of the retaining pressure block 41 extends along the arc of the edge of the disc 2, and is located at the notch 21 at the front end of the meshing of the rack 22 and the gear 31. Preferably, a toothless opening is provided at the starting point of the meshing of the gear 31 with the rack 22 corresponding to the notch 21.

[0027] In this embodiment, the disk 2 has three notches 21 on its edge, and a rack 22 is fixed on each of the disks 2 below the three notches 21. Six bearing members 33 are provided corresponding to the three notches 21, and two bearing members 33 are provided corresponding to each notch 21. The position of each bearing member 33 is set according to the length of the rack 22 and the rotation angle of the gear 31 after meshing with the rack 22.

[0028] Preferably, there are two bearing members 33 corresponding to each notch 21, wherein a bearing 331 is arranged on the axis of one of the bearing members 33 and fits the edge of the disk 2, and two bearings 331 are arranged on the axis of the other bearing member 33 at an upper and lower interval, the lower bearing 331 is arranged at a position fitting the edge of the disk 2, and the upper bearing 331 is arranged at a position fitting the end edge of the retaining pressure block 41.

[0029] Under the action of power, the turntable 1 rotates clockwise with the gear mechanism 3, which is fixed on the turntable 1. The gear mechanism 3 rotates with the turntable 1, and the gear 31 can also rotate around its own center. In order to control the rotation angle of the gear 31 when the gear mechanism 3 rotates with the turntable 1, a bearing member 33 is added to the gear 31, and the bearing 331 of the bearing member 33 always keeps tangent to the disc 2. Under the action of the two retaining bearings 331, the gear 31 will not idle due to external forces.

[0030] By adding a retaining pressure block 41, before the gear 31 meshes with the rack 22, when the front bearing member 33 is about to enter the notch 21, a retaining pressure block 41 with a tension spring 43 is added. The retaining pressure block 41 always presses against the bearing member 33 to ensure that the position of the gear 31 meshing with the rack 22 will not change, thereby achieving the purpose of preventing misaligned teeth.

[0031] The above description is only a specific implementation mode of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made by using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
