[0072] The outer end of the mainspring 2-9 is provided with a mounting hole 2-10, which is connected to the fixing block 7; the inner end of the mainspring 2-9 is provided with a slide groove 2-11, which is connected to the first connecting key 2-12 on the starting shaft 2-1;

[0073] A handle 2-13 is also installed vertically through the starting shaft 2-1.

[0074] As a preferred embodiment of this invention:

[0075] like Figure 1 As shown, a bearing seat 2-14 is installed on the top of the bracket 2-8, and the second transmission shaft 2-7 is inserted into the bearing seat 2-14.

[0076] The top end of the bracket 2-8 is fixedly connected with a bearing seat 2-14, inside of which is a tapered roller bearing, which limits the axial displacement of the second transmission shaft 2-7.

[0077] As a preferred embodiment of this invention:

[0078] like Figure 7 As shown, a connecting hole 3-3 is opened at the center of the connecting plate 3-1, and the connecting hole 3-3 is circumferentially fixed by a second connecting key 2-15 arranged at one end of the second transmission shaft 2-7 passing through the second bevel gear 2-6;

[0079] The end of the second transmission shaft 2-7 passing through the second bevel gear 2-6 is also provided with a thread, and the axial fixation of the connecting plate 3-1 is achieved through the nut 3-4;

[0080] The extraction tank 3-2 is generally in the shape of a hollow spindle, one end of the extraction tank 3-2 is a feed inlet, and the other end is a discharge port. The feed inlet is covered with a feed inlet cover 3-5, and the discharge port is connected to a discharge pipe 3-6;

[0081] The feed inlet cover 3-5 is also connected with a lock buckle 3-7, and the lock buckle 3-7 cooperates with a lock pin 3-8 on the outer wall of the extraction tank 3-2 to fix the feed inlet cover 3-5;

[0082] The discharge pipe 3-6 is also provided with a discharge valve 3-9.

[0083] As a preferred embodiment of this invention:

[0084] like Figure 8 As shown, a porous wine material box 3-10 is fixedly connected in the middle of the extraction tank 3-2, the porous wine material box 3-10 is connected to the outside, and the filter bag is arranged in the porous wine material box 3-10;

[0085] like Fig. 9 As shown, one end of the porous dew wine material box 3-10 communicating with the outside is covered with a material box sealing cover 3-11, and the material box sealing cover 3-11 includes a box plug 3-11-1 and a sealing plate 3-11-2 connected to one side of the box plug 3-11-1, and the shape of the sealing plate 3-11-2 is adapted to the outer surface of the extraction tank 3-2;

[0086] The outer surface of the box plug 3-11-1 is covered with a sealing gasket 3-11-3, and the sealing plate 3-11-2 is arranged with a sealing ring 3-11-4 on the side facing the extraction tank 3-2;

[0087] A locking ring 3-11-5 is also installed on the outer side of the sealing plate 3-11-2.

[0088] As a preferred embodiment of this invention:

[0089] The frame 1 is also provided with fixing holes 9. The frame 1 is fixed to the ground or a desktop etc. through the fixing holes 9 using pins.

[0090] The specific working process of this embodiment is as follows:

[0091] When in use, close the discharge valve 3-9 on the discharge pipe 3-6, open the feed inlet cover 3-5, pour in the base wine, close the feed inlet cover 3-5, put the medicinal materials into the filter bag and then put them into the porous wine material box 3-10, and cover the material box sealing cover 3-11;

[0092] The start shaft 2-1 is turned counterclockwise by the handle 2-13, so that the ratchet 2-2-1 thereon rotates counterclockwise. Because the ratchet 2-2-3 is a plastic product and its structure allows the teeth of the ratchet 2-2-1 to pass through in sequence, the first connecting key 2-12 drives the mainspring 2-9 to rotate counterclockwise as the start shaft 2-1 rotates, and the mounting hole 2-10 outside the mainspring 2-9 is fixedly connected to the fixed shaft fixing block 7, so the mainspring 2-9 accumulates energy during the rotation process.

[0093] After a period of rotation, release the handle 2-13, the spring 2-9 releases energy, and drives the start shaft 2-1 to rotate clockwise. Since the ratchet 2-2-3 and the ratchet 2-2-1 are meshed in the same plane, the gear 2-2-2 starts to rotate. The gear 2-2-2 is meshed with the gear teeth 2-4 on the first transmission shaft 2-3 in the same horizontal plane, so the first transmission shaft 2-3 is driven to start rotating, so that the first bevel gear 2-5 fixed to the top thereof starts to rotate. Since the first bevel gear 2-5 is meshed with the second bevel gear 2-6 and the angle between them is 90°, the meshing rotation of the two causes the second transmission shaft 2-7 to rotate horizontally, and finally drives the extraction system 3 to rotate. During the rotation of the extraction system 3, the extracting liquid inside it passes through the filter bag containing Chinese medicinal materials for many times, so that the medicinal materials are extracted many times. After the rotation stops, choose whether to rotate the handle 2-13 again according to the extraction situation. After the extraction is completed, open the discharge valve 3-9 on the discharge pipe 3-6 to pour out the wine.

[0094] After use, the user can take out the filter bag in the porous wine material box 3-10, inject pure water and start the device to fully clean the extraction tank 3-2, thereby achieving the cleaning and repeated use of the extraction tank 3-2.

[0095] The small-scale liquor production device consists of only three parts, and the assembly between the parts is simple and convenient.

[0096] The above technical solutions are only preferred specific implementation methods of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be thought of by any technician familiar with the field within the technical scope disclosed by the present utility model without creative work are all covered within the protection scope of the present utility model.
