Description

Technical Field

[0001] The invention relates to the technical field of conveying medicinal agricultural products, and in particular to a dust-free medicinal agricultural product transmission line. Background Art

[0002] Medicinal agricultural products refer to plant products that have both medicinal value and agricultural product attributes. They can be used as traditional Chinese medicinal materials, as well as food or functional ingredients, such as Chinese medicinal materials (such as astragalus and wolfberry) and products that are both medicinal and edible (such as red dates and yam).

[0003] Announcement No. CN212502616U includes two fixed plates, two rollers are arranged between the two fixed plates, and conveyor belts are arranged on the two rollers. A first motor is installed on one side of one of the fixed plates, and a dust removal pool is arranged at the bottom of the two fixed plates. The dust removal pool is divided into two rectangular grooves by a partition. A connecting plate is arranged in the rectangular groove, and a plurality of brushes are arranged on the top of the connecting plate. Through the arranged brushes, the two brushes are in contact with the bottom of the conveyor belt to thoroughly wipe off the dust on the conveyor belt to prevent the conveyor belt from working for a long time and accumulating too much dust and floating into the air, affecting the environment of the entire workshop.

[0004] However, in actual operation, the above device uses two fixed-position brush plates to remove dust from the conveyor belt. In the case of long-term use, too much dust will accumulate on the brush plates and easily form lumps, which will seriously affect the cleaning effect on the conveyor belt, resulting in poor dust removal effect, which will affect the transportation quality of medicinal agricultural products.

[0055] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] The invention provides a dust-free transmission line for medicinal agricultural products.

[0057] First embodiment:

[0058] Please combine Figures 1 to 10 , a dust-free medicinal agricultural product transmission line, comprising a truss 1, a transmission mechanism 2, a base 3 and a negative pressure pipe 8;

[0059] A driving mechanism 4 and an intermittent mechanism 5 are installed above the base 3;

[0060] The transmission mechanism 2 includes a transmission motor 21, the output shaft keyway of the transmission motor 21 is connected to a driving pulley 22, a conveyor belt 24 is installed above the truss 1, a driven pulley 25 is connected to a keyway at one end of the conveyor belt 24, and a transmission belt 23 is sleeved on the outer walls of the driving pulley 22 and the driven pulley 25;

[0061] See also Figure 2 and Figure 3 : Start the transmission motor 21 to control the driving pulley 22 to rotate. When the driving pulley 22 rotates, the transmission belt 23 drives the driven pulley 25 to make the conveyor belt 24 rotate and transmit on the truss 1.

[0062] The driving mechanism 4 comprises a first mounting plate 41 and a second mounting plate 43 fixedly mounted on the upper surface of the base 3, a double-headed motor 42 is mounted on the upper surface of the base 3 and on the opposite side of the first mounting plate 41 and the second mounting plate 43, the output shafts at both ends of the double-headed motor 42 are key-connected with a first ratchet 44 and a second ratchet 45 respectively, the second mounting plate 43 is internally rotatably connected with a ratchet ring 46, and a driving rod 47 is fixedly mounted on the outer wall of the ratchet ring 46;

[0063] See also Figure 5 : The rotation direction of the double-headed motor 42 is consistent. When the double-headed motor 42 rotates counterclockwise, the counterclockwise rotation will drive the first ratchet 44 to rotate counterclockwise. When rotating, the outer teeth of the first ratchet 44 will control the ratchet ring 46 in the meshing state to drive the driving rod 47 to rotate counterclockwise;

[0064] In the counterclockwise rotating state, the second ratchet wheel 45 also rotates counterclockwise, and the rotation is clockwise, so the counterclockwise rotating second ratchet wheel 45 will not affect the operation of the ratchet belt wheel 48;

[0065] When the double-headed motor 42 rotates clockwise, the first ratchet wheel 44 will not affect the rotation of the ratchet ring 46, and the second ratchet wheel 45 will control the rotation of the ratchet pulley 48 in the meshing state.

[0066] The intermittent mechanism 5 includes a first positioning plate 51 and a second positioning plate 512 fixedly arranged on the upper surface of the base 3, a bottom plate 52 is installed on the upper surface of the base 3 and on one side of the first positioning plate 51 by bolts, and two limit plates 53 are installed on the upper surface of the bottom plate 52 by bolts, a rotating disk 54 is connected to the outer wall keyway of the driving rod 47, a central axis 55 is rotatably connected inside the first positioning plate 51, an intermittent disk 56 is connected to the keyway at the axis center of the central axis 55, and four notches 57 are opened inside the intermittent disk 56, a positioning pin 58 is fixed on the outer wall of the rotating disk 54, a driving rotating disk 59 is connected to the keyway at the axis center of the central axis 55 and away from the intermittent disk 56, a bearing seat 11 is rotatably connected inside the second positioning plate 512, a driven rotating disk 511 is installed on the inner wall of the bearing seat 11, and four cleaning rollers 510 are rotatably connected to the opposite side of the driving rotating disk 59 and the driven rotating disk 511;

[0067] The upper surface of the negative pressure tube 8 is fixedly provided with branch tubes 9 arranged at equal intervals, and the top ends of the branch tubes 9 are connected and fixedly provided with an adsorption frame 10 .

[0068] See also Figure 6 and Figure 7: When the driving rod 47 rotates, it will drive the rotating disk 54 to rotate inside the limiting plate 53. When the rotating disk 54 rotates, it will drive the positioning pin 58 to rotate inside the notch 57. As the positioning pin 58 continues to rotate with the rotating disk 54, the positioning pin 58 will form an arc rotation force, and the force-controlled notch 57 will drive the intermittent disk 56 to achieve a ninety-degree rotation;

[0069] When the intermittent disk 56 rotates 90 degrees, it will drive the active turntable 59 to rotate. During the 90-degree rotation of the active turntable 59, the top cleaning roller 510 can be rotated to not contact the bottom surface of the conveyor belt 24, while the cleaning rollers 510 on the side can continue to rotate until they contact the conveyor belt 24.

[0070] In this way, the four cleaning rollers 510 can be contacted with the bottom surface of the conveyor belt 24 in sequence. During the transmission of the conveyor belt 24, the dust on the surface will roll off the cleaning rollers 510 to clean and remove dust. In the cleaning process, the user can install a negative pressure machine on the negative pressure pipe 8. The negative pressure generated by the negative pressure pipe 8 can be absorbed and processed centrally through the branch pipe 9 and the adsorption frame 10 to absorb all the dust generated by the cleaning of the cleaning rollers 510.

[0071] After each rotation, the outer wall surface of the rotating cleaning roller 510 will also be attached to the upper surface of the adsorption frame 10, ensuring that the four cleaning rollers 510 can be adsorbed.

[0072] The outer wall of the first ratchet wheel 44 and the inner wall of the ratchet ring 46 are meshed with each other, and two sides of the driving rod 47 are rotatably connected to the two limiting plates 53 .

[0073] The four notches 57 are equidistantly distributed in a ring shape about the axis of the intermittent disk 56 . The outer diameter of the positioning pin 58 matches the inner width of each notch 57 . The axis of the positioning pin 58 is eccentric to the axis of the rotating disk 54 .

[0074] The four cleaning rollers 510 are distributed in an equidistant ring shape about the axis of the driving rotating disk 59 and the driven rotating disk 511 , and the axis of the driven rotating disk 511 is hollow in design.

[0075] Understandable: From Figure 7 As can be seen in the figure, the four notches 57 are equidistantly distributed, dividing the full circle of 360 degrees into four equal parts of 90 degrees in sequence, and the position of the concave surface of each 90-degree arc surface is directly opposite to the axis of each cleaning roller 510, so that the four equal parts can be achieved to ensure intermittent rotation work;

[0076] from Fig. 9 and Fig.10It can be seen that the negative pressure tube 8 is located in the middle of the four cleaning rollers 510, and the rotating driven turntable 511 is hollow in design, and the negative pressure tube 8 is installed in the hollow environment in a through-type manner. Therefore, no matter how the driven turntable 511 rotates, it will not affect the operation of the negative pressure tube 8.

[0077] This embodiment: Compared with the traditional design, this case adopts a continuously rotating rotating disk 54 to control the eccentric positioning pin 58 to generate a rotating force-bearing notch 57 to realize the rotational movement of the intermittent disk 56, and the notch 57 is divided into four equal parts of a perfect circle to realize the four cleaning rollers 510 to intermittently rotate at 90 degrees. Therefore, compared with the traditional fixed cleaning method, during the cleaning process, if one of the cleaning rollers 510 has been cleaning for a certain period of time, it can automatically switch to contact cleaning with other cleaning rollers 510. This can ensure that each cleaning roller 510 can better clean the surface of the conveyor belt 24, ensure the cleaning effect, and better achieve dust-free work. At the same time, it can also extend the cleaning time, and there is no need to frequently replace the cleaning parts. Even if they are replaced, four are replaced at the same time, so that one replacement can clean for longer.

[0078] Second embodiment:

[0079] See also Figure 4 , Fig. 9 , Fig.10 and Fig.11 , also includes a cleaning mechanism 6, the cleaning mechanism 6 includes a first gear 61 fixed on the outer end axis of the driven rotating disk 511, a connecting plate 63 is installed on the upper surface of the base 3 by bolts, a key rod 64 is rotatably connected inside the connecting plate 63, and a second gear 62 is connected to the top keyway of the key rod 64, a limiting rod 66 is fixed inside the base 3, a connecting frame 67 is slidably connected inside the limiting rod 66, a first spring 68 is fixed at the bottom of the connecting frame 67, a fourth gear 611 is connected to the outer wall keyway of the key rod 64, a connecting bearing 613 is pressed on the outer wall of the fourth gear 611, a transmission frame 65 is rotatably connected to the outer wall of the connecting bearing 613, a third gear 610 is rotatably connected to one side of the transmission frame 65, a cleaning roller 69 is rotatably connected to the opposite side of the third gear 610 and the connecting frame 67, and a second spring 612 is fixed at the bottom of the transmission frame 65.

[0080] See also Fig.11: During the working process of the first embodiment, when the driven rotating disk 511 rotates, it drives the first gear 61 to rotate, the first gear 61 rotates and meshes to control the rotation of the second gear 62, the second gear 62 can control the key rod 64 to rotate, the rotation of the key rod 64 can control the fourth gear 611 to mesh and control the rotation of the third gear 610, and the third gear 610 rotates and drives the cleaning roller 69 to rotate automatically relative to the transmission frame 65 and the connecting frame 67;

[0081] The initial setting top position of the cleaning roller 69 is higher than the bottom limit position of the cleaning roller 510. Thus, as the cleaning roller 510 rotates intermittently, the arc surface of the cleaning roller 510 that rotates to the bottom will be forced to contact the upper surface of the cleaning roller 69. When the cleaning roller 69 is under pressure, the transmission frame 65 and the connecting frame 67 on both sides will be controlled to compress the second spring 612 and the first spring 68 in turn, so as to ensure that the cleaning roller 510 can smoothly pass through the cleaning roller 69 at a high position.

[0082] The cleaning roller 69 can preferably be made of a hard brush. When the cleaning roller 510 and the rotating cleaning roller 69 are in contact, the rotating cleaning roller 69 can quickly clean the dust on the cleaning roller 510.

[0083] The first gear 61 and the second gear 62 are meshed with each other, the third gear 610 and the fourth gear 611 are meshed with each other, the bottom end of the key rod 64 is rotatably connected to the base 3, and the key rod 64 passes through the interior of the transmission frame 65 and does not contact the transmission frame 65.

[0084] The key rod 64 passes through the interior of the base 3 and does not contact the base 3 , and the bottoms of the first spring 68 and the second spring 612 are fixedly connected to the base 3 .

[0085] The first gear 61 and the driven rotating disk 511 are of the same hollow design, and the negative pressure tube 8 runs through the axis of the driven rotating disk 511 and the first gear 61 .

[0086] Understandable: Combined Fig.12 It can be seen that the axis of the fourth gear 611 is installed by connecting the bearing 613 and the transmission frame 65, so that the fourth gear 611 can stably rotate on the transmission frame 65, but the axis of the fourth gear 611 only rotates with the key rod 64, so that the fourth gear 611 can not only rotate but also be lifted and lowered.

[0087] In this embodiment: the rotational force of the driven turntable 511 is utilized to synchronously drive the first gear 61 to rotate to achieve a change in the rotational direction, thereby realizing the rotation of the key rod 64, and the change in the rotational direction is realized again through the fourth gear 611 to control the cleaning roller 69 to achieve a linked rotation, and the position of the cleaning roller 69 is higher than the position of the bottom cleaning roller 510, so that when the cleaning roller 510 rotates to the position of the cleaning roller 69, the cleaning roller 69 will be controlled by force to descend and contact the cleaning roller 510, and the rotating cleaning roller 69 can remove dust on the cleaning roller 510. Such a design can ensure that stubborn dust on each cleaning roller 510 that rotates to the position of the cleaning roller 69 can be removed. Secondly, the two rollers are in force contact, which ensures that the removal force is greater during the rotation removal process, so that the dust is removed more thoroughly.

[0088] Third embodiment:

[0089] See also Figure 4 , Figure 5 and Fig.13 The vibration mechanism 7 includes a mounting frame 71 fixed to the upper surface of the base 3, the mounting frame 71 is rotatably connected to a rotating rod 72 inside, two cams 73 are installed on the outer wall of the rotating rod 72, and a vibration roller 74 is rotatably connected to the opposite side of the two cams 73, and a transmission pulley 75 is connected to the keyway at the axis of the rotating rod 72, and a connecting belt 76 is sleeved on the outer wall of the transmission pulley 75 and the ratchet pulley 48.

[0090] See also Figure 5 : The double-headed motor 42 will only affect the control of the second ratchet wheel 45 to control the rotation of the ratchet belt wheel 48 when it rotates clockwise;

[0091] After the conveyor belt 24 has been used for a long time, the user can start the double-headed motor 42 to rotate clockwise, and the ratchet pulley 48 rotates to control the connecting belt 76 to control the transmission pulley 75 to control the rotating rod 72 to rotate in the mounting frame 71. When the rotating rod 72 rotates, it can drive the cam 73 to be eccentric and control the vibration roller 74 to achieve rotation and swing to continuously resist the bottom surface of the conveyor belt 24.

[0092] In this embodiment: after the conveyor belt 24 has been working for a period of time, the cleaning roller 510 can be fixed at an angle, and then the double-headed motor 42 can be started to rotate in the opposite direction. During the rotation, the vibration mechanism 7 can be started to work, and the vibration mechanism 7 generates an eccentric vibration force to continuously resist the vibration control conveyor belt 24. In this way, the dust blocks or stubborn dust generated by the long-term operation on the conveyor belt 24 can be vibrated and removed, ensuring that the surface of the conveyor belt 24 can be thoroughly cleaned after a long period of work, thereby achieving dust-free transmission.

[0093] Fourth embodiment:

[0094] The truss 1 is provided with side plates 12 on both sides, and the material blocking mechanism 13 includes a base 131 fixed on the upper surface of the side plate 12, the upper surface of the base 131 is rotatably connected with a rotating frame 132, the outer wall of the rotating frame 132 is provided with a material blocking plate 133, the inner bottom of the base 131 is provided with a stabilizing plate 134, the inner part of the rotating frame 132 and the concentric part of the base 131 is threadedly connected with a knob 135, and the bottom end of the knob 135 is provided with a frustum 136;

[0095] See also Figure 1 and Fig.14 : In the process of conveying medicinal agricultural products, if medicinal agricultural products of different volumes such as red ginseng slices or kudzu root are to be conveyed, since the sizes of various medicinal agricultural products are different, the user needs to adjust the gap size for the medicinal agricultural products to pass through. The rotating frame 132 can be rotated on the base 131 during adjustment. When the rotating frame 132 rotates, it can drive the baffle plate 133 to adjust the gap size between the two baffle plates 133 on the entire conveyor belt 24, so as to ensure that medicinal agricultural products of different sizes can pass stably and equidistantly. Secondly, after the adjustment is completed, the user needs to rotate the knob 135 to control the descent of the cone 136. When the cone 136 descends to the stabilizing plate 134, the cone surface forms a downward force that is stable, so that the rotating frame 132 and the base 131 can be stably locked and positioned, so that the gap between the baffle plates 133 can be fixed.

[0096] The material distributing mechanism 14 comprises a receiving plate 141 fixedly mounted on the side plate 12, a reciprocating plate 142 is slidably connected to the upper portion of the receiving plate 141, a plurality of material distributing rods 143 are fixedly mounted on the lower surface of the reciprocating plate 142, a receiving frame 144 is fixedly mounted on the upper surface of the side plate 12, a material distributing motor 145 is installed inside the receiving frame 144, a half gear 146 is connected to the keyway of the output shaft of the material distributing motor 145, a reciprocating ring 147 is fixedly mounted on the side wall of the reciprocating plate 142, a first rack 148 and a second rack 149 are fixedly mounted on the inner wall of the reciprocating ring 147;

[0097] The half gear 146 is adapted to the first rack 148 and the second rack 149 .

[0098] See also Figure 1 , Fig.15 and Fig.16: During the unloading process of medicinal agricultural products, the user can start the dispensing motor 145 to control the half gear 146 to rotate clockwise. The clockwise rotation of the half gear 146 will engage and control the second rack 149 to control the reciprocating ring 147 to pull the reciprocating plate 142 to move to the left along the horizontal direction of the receiving plate 141. Then, when the half gear 146 rotates to the position of the first rack 148, it will control the reciprocating ring 147 to pull the reciprocating plate 142 to reset to the right side, so that the reciprocating plate 142 can drive the dispensing rod 143 to move back and forth.

[0099] In this embodiment, a material blocking mechanism 13 and a material dividing mechanism 14 are provided during the conveying of the medicinal agricultural products. The user can adjust the gap between the material blocking plates 133 according to the type of the conveyed medicinal agricultural products, such as kudzu root, red ginseng slices and other products, to ensure that the medicinal agricultural products can be conveyed in a quantitative manner, which is convenient for subsequent packaging or processing.

[0100] Secondly, the reciprocating plate 142 moves back and forth on the conveyor belt 24, which can disperse the conveyed medicinal agricultural products, avoid the occurrence of pile-up, achieve rapid transportation, and avoid leakage and spillage of materials.

[0101] Please refer to Figures 1 to 13 The working principle of the dust-free medicinal agricultural product transmission line provided by the present invention is as follows:

[0102] Step S1: When the double-headed motor 42 rotates counterclockwise, the counterclockwise rotation will drive the first ratchet 44 to rotate counterclockwise. When rotating, the outer teeth of the first ratchet 44 will control the ratchet ring 46 in the meshing state to drive the driving rod 47 to rotate counterclockwise. In the counterclockwise rotating state, the second ratchet 45 also rotates counterclockwise. When rotating, it works with the clockwise teeth. The counterclockwise rotating second ratchet 45 will not affect the work of the ratchet belt wheel 48. When the double-headed motor 42 rotates clockwise, the first ratchet 44 will not affect the rotation of the ratchet ring 46. The second ratchet 45 will control the rotation of the ratchet belt wheel 48 in the meshing state.

[0103] Step S2: When the driving rod 47 rotates, it will drive the rotating disk 54 to rotate inside the limiting plate 53. When the rotating disk 54 rotates, it will drive the positioning pin 58 to rotate into the inside of the notch 57. As the positioning pin 58 continues to rotate with the rotating disk 54, the positioning pin 58 will form an arc rotation force. The force-controlled notch 57 drives the intermittent disk 56 to rotate 90 degrees. When the intermittent disk 56 rotates 90 degrees, it will drive the active rotating disk 59 to rotate. During the 90-degree rotation of the active rotating disk 59, the top cleaning roller 510 can be rotated so that it does not contact the bottom surface of the conveyor belt 24. The cleaning roller 510 on the rotating side will continue to rotate until it contacts the conveyor belt 24, so that the four cleaning rollers 510 can contact the bottom surface of the conveyor belt 24 in turn. During the transmission of the conveyor belt 24, the dust on the surface will roll off the cleaning roller 510 for cleaning and dust removal, and during the cleaning process, the user can install a negative pressure machine on the negative pressure pipe 8 as an external device. The negative pressure generated by the negative pressure pipe 8 can be absorbed and concentratedly processed through the branch pipe 9 and the adsorption frame 10, and the medicinal agricultural product slices can be transmitted on the conveyor belt 24.

[0104] Step S3: As the cleaning roller 510 rotates intermittently, the arc surface of the cleaning roller 510 that rotates to the bottom will be forced to contact the upper surface of the cleaning roller 69. When the cleaning roller 69 is subjected to pressure from above, the transmission frame 65 and the connecting frame 67 on both sides will be controlled to compress the second spring 612 and the first spring 68 in sequence, ensuring that the cleaning roller 510 can smoothly pass through the cleaning roller 69 at a high position;

[0105] The cleaning roller 69 can preferably be made of a hard brush. When the cleaning roller 510 and the rotating cleaning roller 69 are in contact, the rotating cleaning roller 69 can quickly clean the dust on the cleaning roller 510.
