(V) detailed description of the preferred embodiments

In order to make the present invention better understood by those skilled in the art, the technical solution of the present invention will be further described with reference to fig. 1 to 4.

The utility model provides a bright leaf grader of tealeaves, includes frame 1, and a first-order sieve section of thick bamboo 2 is installed to 1 top in the frame, and a 2 outside coaxial arrangement of a first-order sieve section of thick bamboo have a second grade sieve section of thick bamboo 3, and the screen cloth part of a sieve section of thick bamboo can be worked out for the iron wire, also can be worked out for the bamboo strip, and the shape is for the left end is little, the great cylindric of right-hand member, is favorable to arriving the right-hand member after the tealeaves that gets into under the rotation. The mesh of a first-level sieve section of thick bamboo 2 is greater than the mesh of a second grade sieve section of thick bamboo 3, guarantees that finer fresh leaf sieves out from a first-level sieve section of thick bamboo 2, and thick leaf stays in a first-level sieve section of thick bamboo 2, and the finest fresh leaf sieves out from a second grade sieve section of thick bamboo 3, falls on following fine material take out board 7, realizes the tertiary classification of new leaf. The upper discharging hopper 21 and the lower discharging hopper 31 are respectively arranged at the lower right parts of the primary screen drum 2 and the secondary screen drum 3, and the screened coarse leaves and the secondary coarse leaves are respectively screened out from the discharging hopper 21 and the lower discharging hopper 31. A one-level sieve section of

thick bamboo

2 and 3 left end parallel and level of a second grade sieve section of thick bamboo, a right-hand member one-level sieve section of thick bamboo 2 is long in a second grade sieve section of thick bamboo 3, is favorable to preventing that the new leaf through a one-level sieve section of thick bamboo 2 and a second grade sieve section of thick bamboo 3 screening from mixing one.

A2 and a 3 right sides of second grade sieve section of thick bamboo are together fixed by rotating spoke 4, and rotating spoke 4 passes through spoke center pin 42 to be fixed on the spoke bearing frame 41 of frame 1 right side top, and when a 3 was driven to rotate to a second grade sieve section of thick bamboo, a 2 rotates simultaneously, and spoke bearing frame 41 provides the rotatable support of a right-hand member of a sieve section of thick bamboo.

A feed hopper 5 is arranged on the left of the first-stage screen cylinder 2 and the second-stage screen cylinder 3, a feeding pipe 52 is arranged below the right side of the feed hopper 5, and the tail end of the feeding pipe 52 extends into the left side of the first-stage screen cylinder 2 to prevent new leaves from spilling out of the equipment. Hopper 5 provides the support through feeder hopper support 51, and feeder hopper support 51 passes through support fixed plate 53 to be fixed on the left side board of frame 1, and fixed mode is screw fastening fixed.

The motor 6 is arranged below the feed hopper 5, the motor 6 is fixed on a motor fixing plate on the left side of the frame 1, the right end of the motor 6 is connected with a belt wheel 63, and the rightmost end of the motor provides a rotary support through a motor bearing seat 62. The pulleys 63 are provided in two, upper and lower, and transmit rotational power via the belt 61. The belt wheel 63 at the upper end drives the power wheel 65 to rotate, and the rotary support is provided between the belt wheel 63 and the power wheel 65 through the upper bearing seat 64. The two power wheels 65 are symmetrical, the other is a follow-up wheel, a rotatable support is provided, and the two power wheels and the follow-up wheel are identical in structure. The friction block 651 is arranged on the outer side of the power wheel 65, and the friction block 651 is of an irregular multi-tooth structure and is made of flexible wear-resistant materials. The second grade sieve section of thick bamboo 3 and power wheel 65 left end outside rotatable contact, provide support and rotation power by power wheel 65, because the irregular multiple tooth structure of rubbing block 651, rotate along the orbit of rubbing block 651 when second grade sieve section of thick bamboo 3 rotates, produce the vibration that certain decentraction arouses in the rotation process, this kind of vibration has played the purpose that the mesh was plugged up to the new leaf of reduction.

The board 7 is taken out to the thin material that still is equipped with in second grade sieve section of thick bamboo 3 below, and the thin material is taken out board 7 slidable and is installed in the frame below, and the outside is equipped with handle 71, and the new leaf that second grade sieve section of thick bamboo 3 filtered out falls on thin material takes out board 7, and the workman can be convenient takes out board 7 and takes out and shift the new leaf. In order to prevent the new leaves from being thrown out of the device, a rear baffle 11 is arranged behind the machine frame 1.

The left side of the frame 1 is provided with a feeding device 8, as shown in fig. 4, the feeding device 8 comprises a feeding hopper 81, a baffle 82 and a conveyor belt 83, the conveyor belt 83 is provided with a plurality of rows of upward inclined stoppers 831, and the conveyor belt 83 and the stoppers 831 can transmit new leaves in the feeding hopper 81 to the upper end of the feeding device and then transfer the new leaves into the feeding hopper 5. The feeding hopper 81 has larger capacity, can meet the requirement of one-time filling, and does not need to be added for a longer time. The stopper 831 is made of rubber materials, so that the quality of the tea leaves cannot be affected by rusting. Before starting the machine, an operator should set the matching relationship between the feeding speed and the feeding and screening speeds of the feeding device 8, and if the feeding speed is too high, new leaves in the feeding hopper 81 are not in time to enter the screening and overflow; if the feeding speed is too slow, the right screening device idles, and the efficiency is influenced.

The working process is as follows: the operator pours the new leaves into the feeding hopper 81, then starts the machine, and the feeding device 8 conveys the new leaves into the feeding hopper 5; the new leaves in the feed hopper 5 flow into the primary screen cylinder 2 to be rotated and screened, the size of the new leaves is larger than that of the meshes of the primary screen cylinder 2, the new leaves can be screened to the outside from the upper discharge hopper 21, and the size of the new leaves is smaller than that of the meshes of the primary screen cylinder 2 and continues to be rotated and screened in the secondary screen cylinder 3; the size of the new leaves is larger than that of the meshes of the second-level screen cylinder 3, the new leaves can be screened to the outside from the upper discharge hopper 31, and the new leaves smaller than that of the meshes of the first-level screen cylinder 2 fall onto the fine material drawing plate 7. Thus, the classification and screening of the new tea leaves with three specifications and sizes are completed.
