Description

Technical Field

[0001] The utility model belongs to shelling equipment, in particular to a torreya grandis shelling and sorting machine. Background Art

[0002] Torreya grandis fruit has high nutritional value, rich in protein and various trace elements, and can be eaten as dried fruit or pressed for oil. Before pressing the oil from Torreya grandis fruit, the Torreya grandis fruit needs to be shelled. The traditional shelling method is manual shelling, which is not only laborious and labor-intensive, but also has low work efficiency.

[0003] In order to solve the problem of manual shelling, people have invented various Torreya grandis shelling machines. For example, the utility model patent with authorization announcement number CN220799919U discloses an automatic Torreya grandis shelling device. The shelling device gradually reduces the distance between the roller and the transmission tube so that Torreya grandis of different sizes can be shelled at the same time, and the larger Torreya grandis are shelled preferentially through the crushing blocks on the surface of the roller. The shelled Torreya grandis are moved by spiral blades and shelled during the movement. The volume of the shelled Torreya grandis kernels is reduced, which is convenient for passing through the rear end of the roller, reducing the probability of kernel damage.

[0004] This shelling device has the following problems: 1. The shelled Torreya grandis is easily stuck in the hollow gap of the transmission tube when it passes through the spiral blades and moves in the transmission tube, so that it is squeezed and broken by the unshelled Torreya grandis that is subsequently put in, causing the kernel to be damaged; 2. Torreya grandis that are slightly smaller in size are also easily stuck in the hollow gap of the transmission tube after entering the transmission tube, so that shelling cannot be achieved; 3. The air separator arranged below the vibrating screen supplies air to the feed hole of the vibrating screen, so that the Torreya grandis falls from the feed hole into the collecting bucket by weight for collection, and the shells are blown up and collected uniformly from the waste collection port of the vibrating screen; the sorting effect is poor, if the wind force is too strong, the kernel will be easily blown away along with the shells, and if the wind force is too weak, too much shells will easily remain.

[0036] During operation, the sliding frame 14 is slid to the front end, and the Chinese torreya to be processed is manually added into the feeding hopper 12. The motor 34 is started according to the size of the Chinese torreya to be processed, and the outer gear ring 10 and the connecting sleeve 8 are driven to rotate through the pinion 35, thereby driving the upper sand disc 6 to rotate with the connecting sleeve 8, so that the upper sand disc 6 produces axial displacement, and then the gap between the upper and lower sand discs is adjusted to match the size of the Chinese torreya.

[0038] With the linear vibration of the receiving plate 27, the Chinese torreya and shells falling on it are evenly spread and transferred forward. When passing through the lower ports of the two shell suction channels 17 of the air selection device, the negative pressure is formed in the negative pressure wind box 18 after the negative pressure fan 15 is started. The shell of the Chinese torreya after shelling can be sucked into the negative pressure wind box 18 through the shell suction channel 17. The shell baffle plate 16 can block the shell of the Chinese torreya sucked into the negative pressure wind box 18, so that the shell settles and falls into the shell discharge bucket 19 for discharge;

[0039] The shelled Torreya grandis nuts are dropped onto the vibrating tray 22 by the air selection device and transported forward by the vibration of the vibrating tray 22. The shelled Torreya grandis nuts are filtered by the filtering grate bars 29 and can be bagged through the receiving hopper below. The unshelled Torreya grandis nuts are discharged through the discharge port at the front end of the vibrating tray 22.
