Description

Technical Field

[0001] The invention belongs to the technical field of Gastrodia elata cleaning equipment, and particularly relates to a Gastrodia elata cleaning device with a pretreatment function. Background Art

[0002] Gastrodia elata has the effects of calming endogenous wind and stopping convulsions, suppressing hyperactive liver-yang, dispelling wind and dredging collaterals. It is a stem tuber and is a commonly used medicinal material with a large demand. After the finished Gastrodia elata is dug out from the field, a lot of mud remains on its surface and needs to be cleaned before processing.

[0003] Although the existing brush roller type Gastrodia elata cleaning machine can perform batch cleaning operations on Gastrodia elata, since a large amount of soil and other sundries adhere to the surface of newly dug Gastrodia elata, if it is directly put into the cleaning machine for cleaning, a large amount of soil and other sundries will adhere to the brush rollers in the cleaning machine. This not only easily reduces the cleaning effect on Gastrodia elata, but also requires frequent cleaning of the sundries adhering to the brush rollers in the cleaning machine, thereby affecting the cleaning efficiency of the cleaning device for Gastrodia elata. Summary of the Invention

Bladder strips are arranged at the front and rear ends of the sealing belt. The bladder strips are located in the lower support guide groove, and the bladder strips are communicated with the free ends of the hose drawstrings.

[0008] Furthermore, a guiding and clamping assembly is arranged in the box body. The guiding and clamping assembly includes a first guide rod, a support frame, a second guide rod, a U-shaped bracket, a lead screw slider, and a double-threaded lead screw. At least two first guide rods are vertically arranged on the outer side wall of the pretreatment bin and inside the box body, and each first guide rod is rotatably connected to the outer side wall of the pretreatment bin through a support frame. The first guide rod is located on the inner side of the extended hose drawstring. Second guide rods are symmetrically arranged inside the winding roller, and the second guide rods are rotatably installed on the U-shaped frame.

[0009] Furthermore, a sewage discharge conduit is communicated with the front side of the pretreatment bin near the protective box. The inner pipe orifice of the sewage discharge conduit is flush with the surface of the extended sealing belt, and its outer pipe orifice extends outside the pretreatment bin.

[0010] Furthermore, a portal frame is fixedly arranged at the upper bin opening of the pretreatment bin. A plurality of cleaning nozzles are installed on the cross beam of the portal frame, and the plurality of cleaning nozzles are communicated with a water guide pipe.

[0011] Furthermore, a support groove is formed in the right inner wall of the pretreatment bin, and the support groove is aligned with the sealing plate.

[0012] The present invention has the following beneficial effects: 1. In the present invention, a pretreatment bin is arranged at the upper opening of the cleaning box, and a retractable mesh belt and a sealing belt are arranged in the pretreatment bin. When the mesh belt and the sealing belt are laid flat in the pretreatment bin, at this time, the gastrodia elata will be located on the upper surface of the mesh belt, and the cleaning water will wash a large amount of impurities such as soil adhered to the surface of the gastrodia elata and fall onto the surface of the sealing belt. When the mesh belt and the sealing belt are synchronously retracted into the winding mechanism on the left side of the cleaning box, with the synchronous sliding and winding of the mesh belt and the sealing belt, at this time, the pre-cleaned gastrodia elata on the mesh belt will automatically fall into the cleaning box below, and several scrubbing rollers in the cleaning box rotate to perform secondary cleaning on the pre-cleaned gastrodia elata, and the gastrodia elata after secondary cleaning will be discharged through the discharge bin. Therefore, it will not cause a large amount of sundries to accumulate in the cleaning box due to the direct excavation of the gastrodia elata without pre-cleaning and directly putting it into the cleaning box, and it also does not require the operator to manually pre-clean the gastrodia elata, thereby improving the cleaning efficiency and cleaning effect of the cleaning device of the present invention on the gastrodia elata.

[0013] 2. In the present invention, U-shaped blocks are slidably engaged with the front and rear sides of the mesh belt, and bladder-shaped strips are connected to the front and rear sides of the sealing belt. A plurality of U-shaped blocks fixedly arranged at equal intervals in the upper support guide groove are slidably inserted into the limit grooves through the engaging blocks, so as to limit and support the extended mesh belt and prevent the mesh belt from sagging when cleaning the gastrodia elata. Since the width of the support guide groove is greater than the width of the strip-shaped through hole, the bladder-shaped strip will expand in the lower support guide groove, so that the sealing belt can be hermetically extended into the pretreatment bin. And because the bladder-shaped strip expands and is stuck into the support guide groove, it can play a role in limiting and supporting the extended sealing belt, preventing a large amount of sundries, soil and waste water from accumulating on the sealing belt, resulting in a gap between the sealing belt and the bin wall of the pretreatment bin, and further causing the cleaning waste water or sundries to fall into the cleaning box and affecting the secondary cleaning effect of the cleaning box on the gastrodia elata.

[0014] Of course, it is not necessary for any product implementing the present invention to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or position relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0020] Please refer to Figures 1-7 As shown, the present invention is a Gastrodia elata cleaning device with a pretreatment function, including a cleaning tank 1. A plurality of scrubbing rollers 2 are installed inside the cleaning tank 1, and a discharge bin 3 is provided on the side wall of the cleaning tank 1; a pretreatment bin 4 is provided at the upper opening of the cleaning tank 1. A mesh belt 5 is provided inside the pretreatment bin 4, and a sealing belt 6 is provided below the mesh belt 5; a winding mechanism 7 is provided on one side of the pretreatment bin 4, and the winding mechanism 7 is used for winding the mesh belt 5 and the sealing belt 6; a pulling and stretching mechanism 8 is provided on the other side of the pretreatment bin 4, and the pulling and stretching mechanism 8 is used for pulling and stretching the wound mesh belt 5 and sealing belt 6 into the pretreatment bin 4. A sewage discharge conduit 10 communicates with the front side of the pretreatment bin 4 near the protection box 71. The inner pipe orifice of the sewage discharge conduit 10 is flush with the surface of the stretched sealing belt 6, and its outer pipe orifice extends outside the pretreatment bin 4. Specifically, in the present invention, the pretreatment bin 4 is fixedly provided at the upper opening of the cleaning tank 1. When it is necessary to clean Gastrodia elata, first control the winding mechanism 7 and the pulling and stretching mechanism 8 on the left and right sides of the pretreatment bin 4 to work. At this time, the pulling and stretching mechanism 8 will pull the mesh belt 5 and the sealing belt 6 to synchronously slide from left to right in the pretreatment bin 4. At this time, the winding mechanism 7 will release the wound mesh belt 5 and sealing belt 6, so that the mesh belt 5 and the sealing belt 6 are hermetically laid flat in the pretreatment bin 4. Then, pour the Gastrodia elata to be cleaned into the pretreatment bin 4. At this time, the Gastrodia elata will be located on the upper surface of the mesh belt 5. Then, add cleaning water into the pretreatment bin 4. The cleaning water will wash a large amount of impurities such as soil adhered to the surface of the Gastrodia elata and fall onto the surface of the sealing belt 6, and the washed sundries and waste water will be discharged through the sewage discharge conduit 10. When the pre-cleaning of the Gastrodia elata located on the mesh belt 5 is completed, control the winding mechanism 7 to work, and the pulling and stretching mechanism 8 is loosened, so that the mesh belt 5 and the sealing belt 6 will be synchronously retracted into the winding mechanism 7 on the left side of the cleaning tank 1. With the synchronous sliding and winding of the mesh belt 5 and the sealing belt 6, the pretreated Gastrodia elata located on the mesh belt 5 will fall into the cleaning tank 1 below. The plurality of scrubbing rollers 2 in the cleaning tank 1 rotate to perform secondary cleaning on the pre-cleaned Gastrodia elata, and the Gastrodia elata after secondary cleaning will be discharged through the discharge bin 3, thereby improving the cleaning efficiency and cleaning effect of the cleaning device of the present invention on Gastrodia elata.

[0021] In the solution designed by the present invention, the rewinding mechanism 7 includes a protective box 71, a rewinding roller 72, a rotating shaft 73, a guiding roller 74 and a supporting shaft 75. The protective box 71 is fixedly arranged on one side wall of the pretreatment bin 4. Two rewinding rollers 72 are rotatably installed in the protective box 71 through the rotating shaft 73, and the two rewinding rollers 72 are arranged vertically. The mesh belt 5 is wound around the upper rewinding roller 72, and the sealing belt 6 is wound around the lower rewinding roller 72. The free ends of the mesh belt 5 and the sealing belt 6 pass through the strip-shaped through holes 41 opened on the side surface of the pretreatment bin 4 and extend into the pretreatment bin 4. A guiding roller 74 is rotatably arranged on one side of each rewinding roller 72 through a supporting shaft 75. The upper guiding roller 74 contacts the upper surface of the mesh belt 5, and the lower guiding roller 74 contacts the lower surface of the sealing belt 6; Specifically, driven by the servo motor fixedly arranged on the back of the protective box 71, the upper and lower rewinding rollers 72 are driven to rotate through the rotating shaft 73, so as to facilitate the release or rewinding of the mesh belt 5 and the sealing belt 6 wound around the rewinding rollers 72. The guiding rollers 74 supported by the supporting shafts 75 play a role in guiding and supporting the rewound and released mesh belt 5 and sealing belt 6. The vertical height dimension of the strip-shaped through hole 41 is the same as the thickness of the mesh belt 5 and the sealing belt 6. Therefore, when the mesh belt 5 and the sealing belt 6 are rewound, the strip-shaped through hole 41 will scrape off the sundries adhered to the surface of the mesh belt 5 and the sealing belt 6 at this time. The sundries adhered to the surface of the mesh belt 5 will fall onto the surface of the sealing belt 6, and the sundries adhered to the surface of the sealing belt 6 will be discharged through the sewage discharge conduit 10 near the protective box 71.

[0022] In the solution designed by the present invention, the pulling and stretching mechanism 8 includes a box body 81, a winding roller 82, a shaft rod 83, a hose pull rope 84 and a sealing plate 85. The box body 81 is fixedly arranged on the other side wall of the pretreatment bin 4. A winding roller 82 is rotatably installed in the box body 81 through a shaft rod 83. Two hose pull ropes 84 are wound around the winding roller 82 in sections. The free end of each hose pull rope 84 extends into the pretreatment bin 4. A sealing plate 85 is fixedly arranged at the free end of the sealing belt 6, and the top end of the sealing plate 85 extends upward and is connected to the end face of the mesh belt 5; Specifically, when it is necessary to pull and stretch the mesh belt 5 and the sealing belt 6 into the pretreatment bin 4, the output shaft of the servo motor fixedly installed on the back of the box body 81 will drive the winding roller 82 to rotate through the shaft rod 83 at this time. The winding roller 82 will drive the two segmented hose ropes 84 to wind around its surface. Then, the free ends of the wound hose ropes 84 will drive the mesh belt 5 and the sealing belt 6 to be pulled and unfolded from left to right in the pretreatment bin 4 through the sealing plate 85. At this time, the winding roller 72 located in the protective box 71 rotates synchronously to release the wound mesh belt 5 and sealing belt 6, thereby facilitating the synchronous pulling and unfolding of the mesh belt 5 and the sealing belt 6 into the pretreatment bin 4; when the winding roller 72 rotates to wind up the mesh belt 5 and the sealing belt 6, the winding roller 82 rotates in the reverse direction at this time, and the wound hose ropes 84 will be released, so that the mesh belt 5 and the sealing belt 6 connected to the sealing plate 85 will slide synchronously towards the orifice of the strip-shaped through hole 41, thereby facilitating the winding of the mesh belt 5 and the sealing belt 6, and enabling the pre-cleaned gastrodia elata to enter the cleaning box 1 for secondary cleaning operations.

[0023] In the design scheme of the present invention, a sealing support assembly is provided in the pretreatment bin 4. The sealing support assembly includes a U-shaped block 86, a clamping block 87, and a bladder strip 88. Support guide grooves 42 are opened on the front and rear wall surfaces of the pretreatment bin 4 along its length direction, and the support guide grooves 42 communicate with the strip-shaped through hole 41. The connection between the lower support guide groove 42 and the lower strip-shaped through hole 41 is provided with an arc-shaped fillet. A plurality of U-shaped blocks 86 are fixedly installed in the upper support guide groove 42, and the U-shaped notch of the U-shaped block 86 faces the center of the pretreatment bin 4. The front and rear side walls of the mesh belt 5 extend into the U-shaped groove of the U-shaped block 86. Limiting grooves are opened on the surface of the mesh belt 5. Clamping blocks 87 are fixedly installed on the inner wall of the U-shaped notch of the U-shaped block 86, and the clamping blocks 87 slide and insert into the limiting grooves. Bladder strips 88 are provided at the front and rear ends of the sealing belt 6, and the bladder strips 88 are located in the lower support guide groove 42. The bladder strips 88 communicate with the free ends of the hose ropes 84; Specifically, in order to prevent excessive accumulation of gastrodia elata on the stretched mesh belt 5, which may cause the mesh belt 5 to sink and sag, support guide grooves 42 are provided on the front and rear inner walls of the pretreatment bin 4. A plurality of U-shaped blocks 86 fixedly arranged at equal intervals in the upper support guide groove 42 are slidably clamped into the limit grooves through clamping blocks 87, so as to limit and support the stretched mesh belt 5 and prevent the mesh belt 5 from sagging when cleaning the gastrodia elata. When the mesh belt 5 is wound up, the clamping blocks 87 on the U-shaped blocks 86 will disengage from the limit grooves, thus not interfering with the normal winding of the mesh belt 5. An airbag strip 88 is integrally formed on the front and rear sides of the sealing belt 6. After the sealing belt 6 is fully stretched in the pretreatment bin 4, gas is injected through the air duct connected to the flexible hose rope 84, and the gas is injected into the airbag strip 88 through the connected flexible hose rope 84. Since the width of the support guide groove 42 is greater than the width of the strip-shaped through hole 41, the airbag strip 88 will expand in the lower support guide groove 42, so that the sealing belt 6 can be hermetically stretched into the pretreatment bin 4. And because the airbag strip 88 expands and is clamped into the support guide groove 42, it can play a role in limiting and supporting the stretched sealing belt 6, preventing more sundries, dirt and waste water from accumulating on the sealing belt 6, which may cause gaps between the sealing belt 6 and the bin wall of the pretreatment bin 4, resulting in the cleaning waste water or sundries falling into the cleaning box 1 and affecting the secondary cleaning effect of the gastrodia elata in the cleaning box 1. When the sealing belt 6 is wound up, the gas in the airbag strip 88 is pumped out through the flexible hose rope 84, making it shrink to a soft state, so that the winding roller 72 can wind the sealing belt 6 into the protection box 71 for winding and storage.

[0024] In the design scheme of the present invention, a guiding and clamping assembly 9 is arranged in the box body 81. The guiding and clamping assembly 9 includes a first guide rod 91, a support frame 92, a second guide rod 93, a U-shaped bracket 94, a lead screw slider 95 and a double-threaded lead screw 96. At least two first guide rods 91 are vertically arranged on the outer wall of the pretreatment bin 4 and inside the box body 81, and each first guide rod 91 is rotatably connected to the outer wall of the pretreatment bin 4 through a support frame 92. The first guide rod 91 is located on the inner side of the extended flexible hose rope 84. Second guide rods 93 are symmetrically arranged inside the winding roller 82, and the second guide rods 93 are rotatably installed on the U-shaped frame. The second guide rods 93 are in contact with the outer side of the flexible hose rope 84 wound around the winding roller 82, and the second guide rods 93 are arranged in a staggered manner with the first guide rods 91. A lead screw slider 95 is fixedly installed at the top of the U-shaped bracket 94. A double-threaded lead screw 96 is rotatably installed inside the box body 81 and inside the winding roller 82. The double-threaded lead screw 96 is connected to the symmetric lead screw sliders 95 through ball nuts. After the second guide rods 93 slide to align with the first guide rods 91, the distance between the two is less than the diameter of the flexible hose rope 84. Specifically, in order to accurately wind the hose drawstrings 84 located on the front and rear sidewalls of the pretreatment bin 4 onto the front and rear horizontally rotating winding rollers 82, when the mesh belt 5 and the sealing belt 6 are wound up, the winding roller 82 rotates to release the wound hose drawstrings 84. At this time, the output shaft of another servo motor on the back of the box body 81 drives the double - helix lead screw 96 to rotate. Then, the symmetric screw sliders 95 drive the second guide rod 93 to slide towards the center of the protective box through the U - shaped bracket 94. At this time, the sliding second guide rod 93 plays a role in guiding and tensioning the continuously released hose drawstrings 84. And at this time, the first guide rod 91 on the support frame 92 plays a guiding role for the hose drawstrings 84 at the perforations opened on the wall of the pretreatment bin 4, preventing the hose drawstrings 84 from bending and affecting their free sliding. When the winding roller 82 rotates to wind up the hose drawstrings 84, the rotating second guide rod 93 slides towards the end of the box body 81, so that the hose drawstrings 84 can be evenly wound onto the winding roller 82. The cooperation of the sliding second guide rod 93 and the first guide rod 91 supported by the fixed support frame 92 can prevent the continuously released and wound hose drawstrings 84 from becoming scattered on the winding roller 82, thus affecting the normal stretching of the hose drawstrings 84 on the mesh belt 5 and the sealing belt 6, and at the same time affecting the gas entering the bladder - shaped strip 88 to make it expand and seal accurately. When the sealing plate 85 fits against the right - hand inner wall of the pretreatment bin 4, the hose drawstrings 84 are wound to the limit length. Since the hose drawstrings 84 are located between the first guide rod 91 and the second guide rod 93, when the second guide rod 93 slides to align with the first guide rod 91, the second guide rod 93 and the first guide rod 91 will squeeze and seal the hose drawstrings 84, preventing the gas entering the bladder - shaped strip 88 from leaking, thereby improving the sealing effect of the expanded bladder - shaped strip 88 on the stretched sealing belt 6.

[0025] In the design scheme of the present invention, a gantry frame 20 is fixedly installed at the upper hatch of the pretreatment bin 4. A plurality of cleaning nozzles 30 are installed on the cross - beam of the gantry frame 20, and the plurality of cleaning nozzles 30 are communicated with a water guide pipe 40. Specifically, cleaning water is introduced into the plurality of cleaning nozzles 30 through the water guide pipe 40, and the cleaning water is sprayed onto the pretreatment bin 4 or the cleaning box 1 through the plurality of cleaning nozzles 30 to achieve pre - cleaning and secondary cleaning of the gastrodia elata.

[0026] In the design scheme of the present invention, a support groove 43 is opened on the right - hand inner wall of the pretreatment bin 4, and the support groove 43 is aligned with the sealing plate 85. Specifically, the design of the support groove 43 facilitates the support of the sealing plate 85 that slides to the right side of the pretreatment bin 4, and can further support the unfolded mesh belt 5 and sealing belt 6, preventing the gastrodia elata accumulated on the mesh belt 5 and the sundries and waste water accumulated on the sealing belt 6 from being too much and causing the phenomenon of sagging.
