[0036] Embodiment one

[0037] In the present application, the residue extrusion device is used to extract the medicinal liquid from the medicinal residue in the decocting pot 107. The residue extrusion device mainly comprises a residue pressing frame 100, a cover lifting structure 200, an extrusion structure 300 and a pressing head washing structure 400.

[0038] The residue pressing frame 100 is used to connect and fix the cover lifting structure 200, the extrusion structure 300 and the pressing head washing structure 400. Moreover, it can make the three functional structures form a reasonable arrangement in space, and they can be sequentially and alternately executed without interfering with each other when performing the operations of lifting the pot cover 106 and extruding the medicinal residue of the decocting pot 107. At the same time, after the extrusion structure 300 finishes the extrusion action each time, it can also clean the pressing head 307 which contacts the medicinal residue in the pressing head washing structure 400, so as to avoid that the pressing head 307 brings the medicinal liquid into different decocting pots 107, affecting or even destroying the medicinal effect of the medicinal liquid in the decocting pot 107.

[0039] As shown in Figure 1 , x, y, z are direction marks perpendicular to each other, the residue pressing frame 100 comprises a cubic frame composed of a square tube, and the length of the cubic frame in the x direction is greater than the diameter of the decocting pot 107, so that the decocting pot 107 can be stably placed in the residue pressing frame 100. A bracket platform 108 for placing the pressing head washing structure 400 is arranged on the outer side of the cubic frame in the x direction, and the bracket platform 108 is higher than the bottom edge of the cubic frame in the z direction.

[0040] The pressing head washing structure 400 in the present application comprises a washing water tank 401 and a washing water tank top cover 402. The upper surface of the washing water tank 401 has an opening, and the washing water tank top cover 402 covers the top of the washing water tank 401. As shown in Figure 4 , the washing water tank top cover 402 is made of a rectangular flat plate, and an opening is arranged in the middle of the rectangular flat plate, and the opening is circular and its diameter is greater than the diameter of the pressing head 307.

[0041] The extrusion structure 300 fixed on the residue extrusion device comprises a feeding assembly for driving the pressing head 307 to move horizontally and a second lifter 306 for driving the pressing head 307 to move in the vertical direction. The pressing head 307 can enter the washing water tank from directly above the washing water tank 401 in the vertical direction.

[0042] The flushing head structure 400 supplies water to the cavity of the flushing water tank 401 via a water pump 404, giving the water flushing head 307 a greater impact force. This effectively cleans the residue adhering to the surface of the head 307. The flushing water tank top cover 402 covers the flushing water tank 401, preventing splashed water droplets from overflowing to the outside of the flushing water tank 401 during flushing of the head 307. The opening in the flushing water tank top cover 402 ensures that the head 307 can smoothly enter the cavity of the flushing water tank 401 through the opening, ensuring both rapid operation of the flushing head 307 and that the flushing water flow is blocked within the flushing water tank 401.

[0043] Example 2

[0044] The structure is further optimized based on the above embodiments. The pressure head flushing structure 400 includes a flushing water tank 401, a flushing water tank top cover 402, a water pump 404, a spray component 407, and a dregs filter 408. The spray component 407 is installed in the cavity of the flushing water tank 401 and fixed to the side wall of the flushing water tank 401.

[0045] The main body of the spray component 407 is a ring structure to accommodate the pressure head 307 passing back and forth through the opening enclosed by the ring structure, thereby allowing for better rinsing of the entire surface of the pressure head 307.

[0046] like Figure 4 As shown, the flushing water tank top cover 402 is made of a rectangular flat plate with an opening in the center. The opening is circular and its diameter is larger than that of the pressure head 307. A flange may also be provided at the edge of the opening, protruding upwards from the plane of the flushing water tank top cover 402. The perimeter of the flushing water tank top cover 402 is bent with a flange, the flange height being more than 1 cm.

[0047] The flange around the top cover 402 of the flushing water tank allows the top cover 402 of the flushing water tank to be movably fitted onto the top of the flushing water tank 401, and also ensures a more secure fit with the flushing water tank 401.

[0048] Example 3

[0049] The structure is further optimized based on the above embodiment. The annular structure of the spray component 407 is ensured to be horizontally positioned within the cavity of the rinsing water tank 401. The annular structure is formed by bending a hollow metal tube end-to-end, or it can be fabricated using a mold: first, a mold with an annular cavity is made; then, molten metal is injected into the mold; finally, the molten metal is cooled and solidified to form the annular structure. Water outlet holes are provided on the side wall of the metal tube constituting the annular structure.

[0050] The spray member 407 is provided with a plurality of water outlets, which are arranged in a circular line at the lowest part of the annular structure, so as to spray water downward only.

[0051] Preferably, the plurality of water outlets can also be distributed around the entire sidewall of the annular structure.

[0052] More preferably, the plurality of water outlets can be arranged in a plurality of concentric circles with the central axis of the annular structure, and distributed on the sidewall of the annular structure.

[0053] Through the plurality of water outlets provided on the spray member 407, water can be sprayed in any direction around the annular structure from top to bottom and from inside to outside, so as to wash the pressure head 107 entering the washing tank 401 from various angles, and ensure that the pressure head 307 is cleaned.

[0054] Embodiment Four

[0055] On the basis of the above-mentioned embodiments, the structure is further optimized. A straight pipe is arranged in the radial direction of the annular structure, one end of the straight pipe is connected to the outer circumferential sidewall of the annular structure, and the other end is connected to the sidewall of the washing tank 401. The washing tank 401 is made of a metal sheet and is welded, and preferably, the material is selected to be stainless steel sheet. The cavity for containing water on the washing tank 401 is surrounded by four vertical sidewalls and a downwardly concave bottom wall. The four sidewalls are connected head to tail in sequence, and the two adjacent sidewalls are in a vertical relationship.

[0056] The straight pipe is made of a hollow pipe, and the hollow pipe cavity of the straight pipe is in communication with the hollow pipe cavity of the annular structure inside the washing tank 401 and is in communication with the first connecting pipe 405 outside the washing tank 401. In the pressure head washing structure 400, the water pump 404, the first connecting pipe 405 and the second connecting pipe 406, the water outlet of the water pump 404 is connected to the first connecting pipe 405, and the water inlet is connected to the second connecting pipe 406.

[0057] In this way, the spray member 407 can be fixed to the sidewall of the washing tank 401 through a straight pipe, and the pipe of the annular structure is communicated with the water pump 404. The whole spray member 407 is made of a relatively thin material, which greatly reduces the weight of the member, so that the spray member 407 can be stably supported by the sidewall of the washing tank 401. The spray member 407 can be conveniently fixed in the washing tank.

[0058] Embodiment Five

[0059] As Figure 6As shown, on the basis of the above embodiment, the bottom side wall of the flushing water tank 401 is formed with a downward concave surface, and a water outlet is arranged at the lowest part of the concave surface. The concave surface of the bottom wall of the flushing water tank 401 is formed by connecting a first bottom side wall 409 and a second bottom side wall 410 which are inclined at a certain angle relative to the horizontal plane, and the two second bottom side walls 410 are symmetrically distributed on both sides of the first bottom side wall 409.

[0060] The first bottom side wall 409 is isosceles trapezoidal, and is inclined downward at an angle a relative to the horizontal plane, wherein a is less than 15. The second bottom side wall 410 is right-angled trapezoidal, and the two second bottom side walls 410 are symmetrically distributed on both sides of the first bottom side wall 409 and are connected with the inclined edges of the first bottom side wall 409. The top edges of the first bottom side wall 409 and the top edges of the second bottom side wall 410 form a "U"-shaped opening, which abuts against any one of the vertical side walls of the flushing water tank 401 and together forms the water outlet. The edge of the water outlet is rectangular.

[0061] Preferably, a flange is arranged at the water outlet, which is bent outward from the edge. The flanges of the four edges form a rectangular frame parallel to the horizontal plane.

[0062] Through the concave surface of the bottom side wall of the flushing water tank, the flow of sewage to the water outlet can be better guided, and the inclination angle of the concave surface of the bottom side wall can make the flow speed of water greater, thereby avoiding the accumulation of sewage at the bottom side wall and preventing dirt from depositing at the bottom of the flushing water tank.

[0063] Embodiment six

[0064] On the basis of the above embodiment, the structure is further optimized. A drug residue filter 408 is arranged at the water outlet of the flushing water tank, which is used to filter the relatively large drug residue in the flushing water flow. The outer shape of the drug residue filter 408 is a cube, and the inside of the drug residue filter 408 has a cavity and the side wall thereof is a plate with a small thickness.

[0065] A circular pipe-shaped connecting port is further arranged on one side of the drug residue filter 408, which is communicated with the cavity. An open port is arranged on the side opposite to the above-mentioned side, and a plurality of filter wires are arranged in parallel and at intervals on the open port, which are used to filter the drug residue. The side with the filter wires is connected with the water outlet of the flushing water tank. The side with the connecting port is arranged downward, and the connecting port is used to discharge sewage.

[0066] The side with the circular pipe of the drug residue filter 408 is arranged downward, the side above the side with the circular pipe is completely open and uniformly provided with filter wires which are arranged in parallel at equal intervals. The side of the drug residue filter 408 with the filter wires is provided with a flange matched with the rectangular frame, and is connected with the rectangular frame of the water outlet.

[0067] The dregs filter 408 is connected at the water outlet, can filter the dregs with large volume in the water flow of the cleaned and flushed pressure head, avoids the dregs to be accumulated in the drainage pipeline, and prevents the drainage pipeline from being blocked.

[0068] Example Seven

[0069] On the basis of the above-mentioned examples, the structure is further optimized. The spraying member 407 is connected with the water pump 404 through the first connecting pipe 405, for improving the pressure of the water flow entering the spraying member 407.

[0070] In order to ensure that the water pump 404 can continuously supply water to the flushing water tank 401, the pressure head flushing structure 400 can also be provided with a flushing structure buffer 403. The flushing structure buffer 403 is made of a metal sheet and is in a cubic shape, and has a cavity inside, similar to a box.

[0071] The legs are arranged on the flushing water tank, so that a fixed height interval is left between the bottom of the flushing water tank and the placement plane, and the height of the flushing structure buffer 403 is lower than the height of the interval.

[0072] The flushing structure buffer 403 is placed below the flushing water tank 401. The space for storing the flushing structure buffer 403 in the pressure frame 100 is saved, and the volume of the dregs extrusion device is reduced.

[0073] The water inlet of the water pump 404 is communicated with the flushing structure buffer 403 through the second connecting pipe 406. The flushing structure buffer 403 is directly connected with the water supply pipeline, and a certain amount of water is stored inside. The water outlet of the water pump 404 is directly connected with the spraying member 407 in the flushing water tank 401 through the first connecting pipe 405.

[0074] The inner circle diameter of the annular structure is greater than the diameter of the pressure head 307, and the pressure head 307 can smoothly pass through the inner circle of the spraying member 407. The metal pipe side wall constituting the spraying member 407 is provided with water outlets, and a plurality of water outlets surround the entire spraying member 407, so that clean water can be sprayed from any position and any angle of the annular structure, so as to perform omnidirectional flushing on the pressure head 307 entering the flushing water tank 401.

[0075] Example Eight

[0076] In the present application, the dregs extrusion device is used to extract medicinal liquid from the dregs in the decocting pot 107. The dregs extrusion device mainly comprises a pressure frame 100, a cover lifting structure 200, an extrusion structure 300 and a pressure head flushing structure 400.

[0077] The pressing frame 100 is used to connect and fix the cover lifting structure 200, the squeezing structure 300 and the pressing head washing structure 400. Moreover, the three functional structures can be reasonably arranged in space, and they can be sequentially and alternately executed without interference when the cover lifting structure 200 and the squeezing structure 300 perform the operation of lifting the pot cover 106 and squeezing the residue in the decocting pot 107. Meanwhile, after the squeezing structure 300 performs the action of squeezing the residue each time, the pressing head 307 which contacts the residue can be cleaned in the pressing head washing structure 400, so as to avoid that the pressing head 307 brings the medicinal liquid into different decocting pots 107, which affects or even destroys the medicinal effect of the medicinal liquid in the decocting pot 107.

[0078] As shown in Figure 1 , x, y, z are direction marks perpendicular to each other, the pressing frame 100 includes a cubic frame composed of a square tube, the length of the cubic frame in the x direction is greater than the diameter of the decocting pot 107, so that the decocting pot 107 can be stably placed in the pressing frame 100. A bracket platform 108 for placing the pressing head washing structure 400 is arranged on the outer side of the cubic frame in the x direction, and the bracket platform 108 is higher than the bottom edge of the cubic frame in the z direction.

[0079] A decocting pot placing table 105 is arranged in the interior of the cubic frame, which is flat and horizontally arranged, and the width of the decocting pot placing table 105 matches the size of the cubic frame in the x direction, and the length of the decocting pot placing table 105 matches the size of the cubic frame in the y direction. The height of the decocting pot placing table 105 can be adjusted according to the height of the decocting pot 107, so that the pot cover clamping jaw 213 of the cover lifting structure 200 can just grab the pot cover 106.

[0080] Alternatively, the decocting pot placing table 105 is replaced by a conveying belt which can convey the decocting pot, and the width of the decocting pot conveying belt matches the size of the cubic frame in the x direction, and the length of the decocting pot conveying belt matches the size of the cubic frame in the y direction. The conveying surface of the decocting pot conveying belt is horizontally arranged, and the height of the decocting pot conveying belt can be adjusted according to the height of the decocting pot 107, so that the pot cover clamping jaw 213 of the cover lifting structure 200 can just grab the pot cover 106.

[0081] Further, in order to facilitate the cover lifting structure 200 and the squeezing structure 300 to alternately perform specific actions on the decocting pot 107 placed in the cubic frame and leave a space for avoiding, the moving route of the action components of the cover lifting structure 200 and the squeezing structure 300 can be arranged as a layout diverging to all directions with the decocting pot 107 as the center.

[0082] Preferably, as shown in Figure 1 , the cover lifting structure 200 and the squeezing structure 300 are vertically arranged in the horizontal plane, the horizontal feeding motion of the cover lifting structure 200 is along the y direction, and the horizontal feeding motion of the squeezing structure 300 is along the x direction.

[0083] The cubic frame comprises a first pressure frame link 101, a second pressure frame link 102, a third pressure frame link 103 and a fourth pressure frame link 104. As shown, in two vertical sides of the cubic frame perpendicular to the y direction, the first pressure frame link 101 is connected in the left vertical side and is distributed along the x direction, and the fourth pressure frame link 104 is connected in the right vertical side and is distributed along the x direction. Figure 1

[0084] In two vertical sides of the cubic frame perpendicular to the x direction, the second pressure frame link 102 is connected in the left vertical side and is distributed along the y direction. One end of the third pressure frame link 103 is connected to the middle of the second pressure frame link 102 and is parallel to the first pressure frame link 101. The spacing between the third pressure frame link 103 and the first pressure frame link 101 is equal to the length of the cover lifting structure 200.

[0085] The first pressure frame link 101, the second pressure frame link 102 and the third pressure frame link 103 are at the same height in the cubic frame, and the fourth pressure frame link 104 is lower than the first pressure frame link 101 in the cubic frame.

[0088] The cover lifting sliding block 205 is pushed by the first sliding block driving rod 204 and can move back and forth on the first sliding block driving rod 204 along the central axis direction of the first sliding block driving rod 204. The cover lifting sliding block 205 is sleeved on the first sliding block driving rod 204. The cross section of the cover lifting sliding block 205 is rectangular, and three sleeving holes are arranged thereon, the sleeving hole at the center position is larger, and the sleeving holes at the two sides are smaller.

[0089] The first sliding block driving rod 204 is in the shape of a long straight cylinder and can drive the cover lifting sliding block 205 through threaded contact. An external thread is arranged on the outer surface of the first sliding block driving rod 204, and a hole with an internal thread is arranged on the cover lifting sliding block 205. The first sliding block driving rod 204 is sleeved into the threaded hole of the cover lifting sliding block 205. Through the internal and external threads matched with each other, the cover lifting sliding block 205 can be driven to move along the central axis direction of the first sliding block driving rod 204 by rotating the first sliding block driving rod 204.

[0090] ​The first sliding block driving rod 204 can also drive the cover lifting sliding block 205 by magnetic attraction. The cover lifting sliding block 205 is sleeved on the first sliding block driving rod 204.

[0117] The second driving rod power input block 301 can also be driven by gas or liquid to drive the extrusion head sliding block 302. An installation hole for fixing the second driving rod power input block 301 and the extrusion horizontal guide rod 303 is arranged on one end face of the second driving rod power input block 301. An inlet for introducing gas or liquid is arranged on the other end face of the second driving rod power input block 301, and then the inlet is communicated with the installation hole connected with the second driving rod power input block 301. When the gas or liquid is filled from the inlet, the magnet installed in the second driving rod power input block 301 can be pushed by the gas or liquid, so that the magnet can reciprocate in the through hole of the second driving rod power input block 301.

[0118] The extrusion head 307 guide rod is made of an elongated straight rod with smooth outer surface, and the cross section of the straight rod can be circular or polygonal. The extrusion horizontal guide rod 303 can be made of a solid straight rod or a hollow straight rod.

[0119] The second driving rod power input block 301, the extrusion horizontal guide rod 303, the second driving rod power input block 304 and the extrusion head sliding block 302 constitute the feeding assembly of the extrusion structure 300, which is used to drag the extrusion head 307 to move linearly along the x direction, so that the extrusion head 307 moves to the position directly above the decoction pot 107, or moves from the position of the decoction pot 107 to the standby position to avoid the pot opening of the decoction pot 107.

[0120] The extrusion horizontal guide rod 303 and the second driving rod power input block 304 are arranged in parallel, and the two extrusion horizontal guide rods 303 are symmetrically distributed on both sides of the second driving rod power input block 304.
