DETAILED DESCRIPTION

[0013] The present invention is further described in detail below through specific implementation modes:

[0014] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides a tea color sorting machine, including a screening frame and a driving assembly;

[0015] The screening frame comprises a support frame 1 and a screen 2 reciprocatingly arranged in a vertical direction in the support frame 1;

[0016] The driving assembly includes a reciprocating horizontal adjustment part 3 connected to the support frame 1 and a reciprocating vertical adjustment part 4 connected to the screen 2, and the reciprocating vertical adjustment part 4 is connected to the reciprocating horizontal adjustment part 3 for transmission.

[0017] In this embodiment:

[0018] The tea color sorter also includes a main body 5, a screening frame is movably arranged in the main body 5, a color sorting lens and a blow pipe are arranged below one side of the discharge end of the screen 2, a receiving funnel 6 is arranged below the support frame 1, and the discharge end of the receiving funnel 6 extends into a residual material box fixedly arranged on the outer wall of the main body 5, and a receiving box is arranged below the receiving funnel 6; the details of this structure can refer to the corresponding structure in the background technology.

[0019] The tea leaves are added to the screen 2 from the feed inlet, and the reciprocating horizontal adjustment part 3 is operated to make the support frame 1 drive the screen 2 to reciprocate horizontally in the main body 5. At the same time, the reciprocating horizontal adjustment part 3 also drives the reciprocating vertical adjustment part 4 during operation to drive the screen 2 to reciprocate in the vertical direction in the support frame 1, so that the tea leaves are constantly rolling on the screen 2; the dust and the broken pieces pass through the screen 2 and fall into the receiving funnel 6 and then slide into the residual material box for collection, and the separated tea leaves fall from the discharge end of the screen 2, and the tea leaves are irradiated by the color sorting lens and then the yellow leaves and tea stems in the tea leaves are blown out through the blow pipe, so that the sorted tea leaves and the sorted yellow leaves and tea stems are respectively collected in different receiving boxes; in the tea color sorting machine, the cooperation of the reciprocating vertical adjustment part 4 and the reciprocating horizontal adjustment part 3 increases the rolling degree of the tea leaves on the screen 2, and improves the separation ability of the dust and broken pieces mixed in the tea leaves.

[0020] like Figure 1 and Figure 2 As shown, according to another embodiment of the utility model, in the tea color sorting machine, the reciprocating horizontal adjustment part 3 includes a guide rod 31 and a driving unit;

[0021] Among them, at least one of the guide rods 31 is slidably connected to the support frame 1;

[0022] The driving unit is connected to the reciprocating vertical adjustment part 4 and is also connected to an adjustment wheel 32 . The eccentric position of the adjustment wheel 32 is connected to the support frame 1 via a traction rod 33 .

[0023] In this embodiment:

[0024] There are two guide rods 31 , and the two guide rods 31 are arranged at intervals in a direction perpendicular to the sliding direction of the support frame 1 . Each guide rod 31 is arranged along the sliding direction of the support frame 1 to stably guide the reciprocating horizontal movement of the support frame 1 .

[0025] When the driving unit is in operation, it drives the adjusting wheel 32 to rotate. During the rotation process, the adjusting wheel 32 causes the traction rod 33 to pull the support frame 1, so that the support frame 1 slides back and forth horizontally on the guide rod 31, thereby driving the screen 2 to slide back and forth horizontally; at the same time, the driving unit also drives the reciprocating vertical adjustment part 4 to operate, and the reciprocating vertical adjustment part 4 causes the screen 2 to slide back and forth in the vertical direction, thereby enhancing the tumbling degree of the tea leaves on the screen 2 and improving the separation ability of the dust and fragments mixed in the tea leaves.

[0026] Furthermore, the driving unit includes a driver 34 and a driving bevel gear 35 connected to the driver 34, and the adjusting wheel 32 is a driven bevel gear, which meshes with the driving bevel gear 35; wherein the driver 34 can be a reduction motor to drive the driving bevel gear 35 to rotate, and the driving bevel gear 35 drives the driven bevel gear to rotate, and the driven bevel gear pulls the support frame 1 through the traction rod 33 to make the support frame 1 reciprocate horizontally on the guide rod 31; the traction rod 33 and the driven bevel gear and the support frame 1 are all rotationally connected.

[0027] A protective shell 36 is fixedly mounted on the outer wall of the main body 5, and the driver 34, the active bevel gear 35 and the driven bevel gear are all arranged in the protective shell 36. A clearance hole is opened on the main body 5, and the traction rod 33 passes through the clearance hole to move freely.

[0028] Based on the above scheme:

[0029] The driving unit also includes a driving sector gear 37, a transmission circular gear and a spline shaft 38;

[0030] The transmission circular gear is meshed with the driving sector gear 37, and a belt transmission structure is connected to the transmission circular gear;

[0031] The spline shaft 38 is arranged along the moving direction of the support frame 1 and one end of the spline shaft 38 is connected to the belt transmission structure, and the other end of the spline shaft 38 is spline-connected to the reciprocating vertical adjustment part 4 .

[0032] The driving sector gear 37 is specifically connected to the output shaft of the driver 34. The driver 34 rotates the driving sector gear 37 during operation, and the driving sector gear 37 intermittently cooperates with the transmission circular gear to make the transmission circular gear rotate intermittently. The transmission circular gear is intermittently transmitted through the belt transmission structure and the spline shaft 38 in turn, and the screen 2 is intermittently driven to reciprocate in the vertical direction. The driving sector gear 37 can also be a circular gear to drive the screen 2 to continuously reciprocate in the vertical direction.

[0033] The belt transmission structure and the spline shaft 38 are driven according to the space arrangement requirements during the installation process, so that the driver 34 can move the screen 2 in different directions during operation to increase the rolling degree of the tea leaves on the screen 2 and improve the separation ability of the dust and debris mixed in the tea leaves. The belt transmission structure is an existing one, which is composed of two pulleys and a belt, and the two pulleys are connected to the transmission circular gear and the spline shaft 38 in a one-to-one correspondence.

[0034] like Figure 2 As shown, according to another embodiment of the utility model, in the tea color sorting machine, the reciprocating vertical adjustment part 4 includes a cam 41 and an adjustment frame;

[0035] Wherein, the cam 41 is connected to the reciprocating level adjustment part 3;

[0036] The adjustment frame is fixedly connected to the screen 2 and slidably connected to the support frame 1 along the vertical direction, and the support frame 1 and the cam 41 always slide against each other.

[0037] Here, the cam 41 is spline-connected with the spline shaft 38, so that the spline shaft 38 drives the cam 41 to rotate during the rotation process, and the cam 41 drives the adjustment frame to reciprocate in the vertical direction during the rotation process, thereby driving the screen 2 to reciprocate in the vertical direction. In addition, the connection between the cam 41 and the spline shaft 38 will not limit the reciprocating horizontal movement of the adjustment frame.

[0038] Based on the above scheme:

[0039] The adjustment frame includes a support column 42 and a matching block 43;

[0040] Among them, at least one of the support columns 42 is connected to the support frame 1 in a sliding manner in the vertical direction, the top of each support column 42 is fixedly connected to the screen 2, and the bottom end thereof is elastically supported against the support frame 1 by an elastic support member 44, and the bottom end of each support column 42 is also connected by a connecting strip:

[0041] The matching block 43 is fixedly connected to the connecting strip and is always slidably opposed to the cam 41 .

[0042] Here, there are two support columns 42 and they are arranged at intervals at the bottom of the screen 2. A large head is formed at the bottom of each support column 42. The elastic support member 44 is a support spring. The support spring is sleeved on the support column 42 and abuts against the large head at the bottom of the support column 42 and the bottom of the support frame 1, so as to cooperate with the cam 41 to smoothly and stably make the screen 2 reciprocate in the vertical direction; when the cam 41 rotates, it drives the matching block 43 to reciprocate in the vertical direction, and the matching block 43 is sequentially transmitted through the connecting bar and the support column 42 to make the screen 2 reciprocate in the vertical direction.

[0043] The support column 42 is connected to the support frame 1, and the support frame 1 can guide the movement of the support column 42 to improve the stability of the reciprocating motion of the screen 2 in the vertical direction.

[0044] In order to improve the transmission stability between the cam 41 and the matching block 43, a limiting notch is opened on the matching block 43, and the cam 41 is partially slidably connected in the limiting notch; the limiting notch is used to limit the cam 41, so that the cam 41 and the matching block 43 always maintain a sliding abutment state, and prevent the cam 41 from moving along its axial direction and disengaging from the matching block 43.

[0045] like Figure 2As shown, according to another embodiment of the utility model, in the tea color sorting machine, the discharge end of the screen 2 is bent upward to form a debris limiting tail.

[0046] Here, the design of the debris limiting tail can play a certain limiting role on dust and debris, reduce the discharge of dust and debris from the discharge end of the screen 2, and improve the cleanliness of the tea leaves discharged from the discharge end of the screen 2.

[0047] like Figure 2 As shown, according to another embodiment of the utility model, a tea color sorting machine is described, wherein the support frame 1 includes an enclosure with one side designed to be open, the screen 2 is slidably arranged in the enclosure along the vertical direction, and the discharge end of the screen 2 passes through the opening of the enclosure to discharge the separated tea leaves, so as to carry out the subsequent separation of yellow leaves and tea stalks; a plurality of support rods 11 are arranged at intervals at the bottom of the enclosure along the length direction of the screen 2, the guide rods 31 are slidably connected through the corresponding support rods 11, and the support columns 42 are also slidably connected through the corresponding support rods 11; the cooperation between the enclosure and the support rods 11 forms a support for the screen 2, while reducing the obstruction to the screen 2 during the screening process.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
