Description

Technical Field

[0001] This invention relates to shiitake mushroom sorting technology, specifically to an automatic shiitake mushroom sorting machine. Background Technology

[0002] Shiitake mushrooms, also known as flower mushrooms, fragrant mushrooms, shiitake, winter mushrooms, and fragrant fungi, belong to the genus Lentinus in the family Agaricaceae. From top to bottom, a shiitake mushroom consists of a cap, annulus, and gills. Basidiomyelitis form on the gills, and each basidia produces four spores. Shiitake mushrooms have a thick, tender texture, a delicious flavor, a unique aroma, and are rich in nutrients. They are considered both food and medicine, possessing high nutritional value.

[0003] Medicinal and health-promoting value.

[0004] After the shiitake mushrooms are dried, they need to be sorted to classify them according to their different sizes. The common sorting method is to use multiple layers of sieves with different pore sizes to separate the shiitake mushrooms of different sizes.

[0005] When sieving shiitake mushrooms using a sieve plate, vibration is often used to propel the mushrooms forward, which can also accelerate the sorting process to some extent. For example, Chinese utility model patent CN219664444U discloses a shiitake mushroom sorting machine that uses a vibrating motor 208 to drive the screening plate 3 to vibrate up and down, allowing the shiitake mushrooms to pass through the sieve holes 301 into the next layer of screening rack 2 for multi-stage screening. This results in high screening efficiency and good screening quality. However, in practical applications, when the size of the shiitake mushrooms is very close to the size of the sieve holes, the mushrooms get stuck in the sieve holes. The vibration of the sieve plate cannot vibrate them out of the sieve holes. If the mushrooms are stuck in the sieve holes for a long time, the sieve holes will not be able to screen other shiitake mushrooms, thus reducing the screening efficiency. Summary of the Invention

[0006] The purpose of this invention is to provide an automatic mushroom sorting machine to overcome the above-mentioned shortcomings in the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an automatic mushroom sorting machine, comprising a screening box, several screen plates with gradually decreasing screen apertures, a feeding platform, and further comprising:

[0008] The mounting plate is fixedly installed at the bottom of the sieve plate;

[0009] A dredging mechanism is provided on the outside of an installation plate. The dredging mechanism includes a reciprocating screw rotatably connected to the inner wall of the installation plate. A connecting bar is driven to the outside of the reciprocating screw. A groove is provided on the inner side of the connecting bar. A connecting plate is slidably connected to the inner side of the groove in the vertical direction. A top rod corresponding to the sieve hole is fixedly connected to the top of the connecting plate. A guide rod is fixedly connected to the bottom of the sieve plate. The outer surface of the connecting bar is slidably connected to the guide rod.

[0010] A reciprocating lifting mechanism is installed outside the connecting plate, and the reciprocating lifting mechanism is used to drive the lifting rod to perform reciprocating motion in the vertical direction.

[0011] Furthermore, the reciprocating screw and the guide rod are respectively arranged on both sides of the bottom of the sieve plate.

[0012] Furthermore, the reciprocating lifting mechanism includes a slide rod that is slidably connected to the inner side of the slide groove in the horizontal direction. A lifting block is fixedly connected to the side of the slide rod near the connecting bar. A lifting inclined surface is provided on one side of the lifting block. A lifting groove is opened at the bottom of the connecting plate. A guide inclined surface is provided on the inner wall of the lifting groove. Corresponding positioning parts are provided on the outside of the lifting block and inside the lifting groove. A return spring is fixedly connected between the top surface of the connecting bar and the inner wall of the slide groove. A power assembly is provided on the outside of the slide rod.

[0013] Furthermore, the lifting block is disposed on the inner side of the lifting groove, and the shape and size of the lifting block are matched with the lifting groove. The lifting inclined surface is slidably connected to the guide inclined surface, and the end of the lifting inclined surface away from the reciprocating screw is inclined downward.

[0014] Furthermore, the power assembly includes a drive rod fixedly connected to the end of the slide rod. The end of the drive rod away from the slide rod is provided with a symmetrical first slope. A first peak is provided at the intersection of the two first slopes. A plurality of protrusions are provided at equal intervals along the axis of the reciprocating screw on the surface of the mounting plate. A symmetrical second slope is provided on the surface of the protrusions. A second peak is provided at the intersection of the two second slopes.

[0015] Furthermore, the end face shape of the top rod and the shape of the sieve hole are both circular, and the diameter of the end of the top rod is 1 / 3 of the diameter of the sieve hole. The distance between the end of the second slope away from the second peak and the second peak along the axis of the reciprocating screw is equal to the diameter of the top rod. The positions of the first peak and the second peak are respectively in the same vertical plane with the center of the corresponding sieve hole. When the first peak moves to contact the second peak, the connecting plate drives the top rod to move through the sieve hole.

[0016] Furthermore, the length and slope of the first slope are the same as those of the second slope.

[0017] Furthermore, it also includes: an anti-slip conveyor belt, which is installed on the inner side of the feeding platform, and the conveying end position of the anti-slip conveyor belt corresponds to the screen plate;

[0018] There are two support plates, which are symmetrically installed on both sides of the top of the feeding table, and the top of the two support plates is fixedly installed with a mounting box.

[0019] An anti-stacking mechanism is provided at the bottom of the mounting box. The inner side of the mounting box has two symmetrical guide grooves. The inner sides of the two guide grooves are slidably connected to two translation plates. The bottom of each translation plate is fixedly connected to a rubber curtain. The two translation plates are staggered. The mounting box is equipped with a drive assembly, which is used to drive the two translation plates to perform alternating reciprocating motion.

[0020] Furthermore, the drive assembly includes a disc rotatably connected to the inner side of the mounting box, with two linkage rods rotatably connected to the surface of the disc. The two linkage rods are rotatably connected to two translation plates respectively. An electric cylinder is fixedly connected inside the mounting box, and the telescopic end of the electric cylinder is fixedly connected to one of the translation plates.

[0021] Furthermore, the two linkage rods are arranged symmetrically at the center, and the bottom surface of the rubber curtain is flush with the upper surface of the anti-slip conveyor belt. When the anti-slip conveyor belt moves the shiitake mushrooms that are in direct contact with it, the shiitake mushrooms can push the bottom of the rubber curtain to move and bend.

[0022] Compared with the prior art, the automatic mushroom sorting machine provided by the present invention has the following beneficial effects:

[0023] 1. This automatic mushroom sorting machine uses a reciprocating screw to drive the connecting bar to reciprocate. During the movement of the connecting bar, the reciprocating lifting mechanism and the return spring work together to drive the top rod to perform a reciprocating lifting and resetting action. This can effectively push out the mushrooms that are blocked in the screen holes, thus avoiding the situation where mushrooms are stuck in the screen holes for a long time, which would reduce the screening efficiency and deteriorate the screening effect.

[0024] 2. This automatic mushroom sorting machine, through the use of an anti-stacking mechanism and the cooperation of an anti-slip conveyor belt, can clean up the accumulated mushrooms during the mushroom conveying process and spread them more evenly on the surface of the anti-slip conveyor belt. This makes the mushrooms conveyed to the screen plate more loosely distributed and free from stacking, which is beneficial to the mushroom sorting process. Attached Figure Description

Detailed Implementation

[0035] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] Example 1:

[0037] Please see Figures 1-5 An automatic mushroom sorting machine includes a screening box 1, several screen plates 2 with gradually decreasing screen apertures 3, and a feeding table 4, and also includes:

[0038] Mounting plate 5 is fixedly installed at the bottom of screen plate 2;

[0039] The unblocking mechanism 6 is located outside the mounting plate 5. The unblocking mechanism 6 includes a reciprocating screw 61 rotatably connected between the inner walls of the mounting plate 5. A connecting bar 62 is connected to the outside of the reciprocating screw 61. A groove is provided on the inner side of the connecting bar 62. A connecting plate 63 is slidably connected to the inner side of the groove in the vertical direction. A top rod 64 corresponding to the sieve hole 3 is fixedly connected to the top of the connecting plate 63. A guide rod 65 is fixedly connected to the bottom of the sieve plate 2. The outer surface of the connecting bar 62 is slidably connected to the guide rod 65.

[0040] The reciprocating lifting mechanism 7 is located outside the connecting plate 63, and the reciprocating lifting mechanism 7 is used to drive the lifting rod 64 to perform reciprocating motion in the vertical direction.

[0041] Specifically, the reciprocating screw 61 and the guide rod 65 are respectively set on both sides of the bottom of the screen plate 2, so that when the reciprocating screw 61 rotates, it can drive the connecting bar 62 to perform a smooth linear reciprocating motion under the guidance of the guide rod 65.

[0042] In this embodiment, the reciprocating lifting mechanism 7 includes a slide rod 71 that is slidably connected to the inner side of the slide groove in the horizontal direction. A lifting block 72 is fixedly connected to the side of the slide rod 71 near the connecting bar 62. A lifting inclined surface 73 is provided on one side of the lifting block 72. A lifting groove 74 is opened at the bottom of the connecting plate 63. A guide inclined surface 75 is provided on the inner wall of the lifting groove 74. Corresponding positioning parts 76 are provided on the outside of the lifting block 72 and inside the lifting groove 74. A return spring 77 is fixedly connected between the top surface of the connecting bar 62 and the inner wall of the slide groove. A power assembly 78 is provided on the outside of the slide rod 71.

[0043] Specifically, the lifting block 72 is set on the inner side of the lifting groove 74. The shape and size of the lifting block 72 are matched with the lifting groove 74. The lifting inclined surface 73 is slidably connected to the guide inclined surface 75. The end of the lifting inclined surface 73 away from the reciprocating screw 61 is inclined downward, so that when the lifting block 72 moves away from the reciprocating screw 61, under the guiding action of the lifting inclined surface 73 and the guide inclined surface 75, the connecting plate 63 is subjected to a vertical component force, so that the connecting plate 63 can move upward and drive the top rod 64 to move upward.

[0044] In this embodiment, the power assembly 78 includes a drive rod 781 fixedly connected to the end of the slide rod 71. The end of the drive rod 781 away from the slide rod 71 is provided with a symmetrical first slope 782. A first peak 783 is provided at the intersection of the two first slopes 782. A plurality of protrusions 784 are provided at equal intervals along the axis of the reciprocating lead screw 61 on the surface of the mounting plate 5. A symmetrical second slope 785 is provided on the surface of the protrusions 784. A second peak 786 is provided at the intersection of the two second slopes 785.

[0045] Specifically, the end face shape of the push rod 64 and the shape of the sieve hole 3 are both circular, and the diameter of the end of the push rod 64 is 1 / 3 of the diameter of the sieve hole 3. The distance between the end of the second slope 785 away from the second peak 786 and the second peak 786 along the axis of the reciprocating screw 61 is equal to the diameter of the push rod 64. This allows the push rod 64 to perform a complete upward and reset action when the connecting bar 62 passes through the protrusion 784 under the drive of the reciprocating screw 61. The positions of the first peak 783 and the second peak 786 are respectively in the same vertical plane as the center of the corresponding sieve hole 3. When the first peak 783 moves to contact the second peak 786, the connecting plate 63 drives the push rod 64 to move through the sieve hole 3.

[0046] Furthermore, the length and inclination of the first slope 782 are the same as those of the second slope 785, which makes the fit between the first slope 782 and the second slope 785 higher when they come into contact, thus making the transmission stability of the drive rod 781 better.

[0047] Furthermore, the drive rod 781 has three positional states relative to the protrusion 784 during movement:

[0048] In the first position state, that is, when the drive rod 781 moves to the position where the end of the first slope 782 away from the first peak 783 contacts the end of the second slope 785 away from the second peak 786, the push rod 64 moves to the position where it can just enter the inside of the sieve hole 3, that is, the push rod 64 enters the coverage area of ​​the sieve hole 3.

[0049] The second position is when the drive rod 781 moves to the position where the first peak 783 contacts the second peak 786. At this time, the top rod 64 passes through the sieve hole 3 and is concentric with the sieve hole 3.

[0050] The third position is when the drive rod 781 moves to the position where the end of the first slope 782 on the other side away from the first peak 783 contacts the end of the second slope 785 on the other side away from the second peak 786. At this time, the push rod 64 exits from the sieve hole 3 and is still within the coverage area of ​​the sieve hole 3.

[0051] During use, the reciprocating screw 61 drives the connecting bar 62 to perform linear reciprocating motion. During the movement of the connecting bar 62, it drives the driving rod 781 to move, causing the first slope 782 on the driving rod 781 to move along the second slope 785 on the protrusion 784, causing the driving rod 781 to move towards the inside of the chute and pushing the slide bar 71 to move towards the inside of the chute. The movement of the slide bar 71 drives the lifting block 72 to move, causing the lifting slope 73 and the guide slope 75 to slide relative to each other, so that the connecting plate 63 can be lifted upward and the return spring 77 is compressed. The upward movement of the connecting plate 63 drives the top rod 64 to move upward, so that it can push out the mushrooms stuck inside the sieve hole 3.

[0052] As the connecting bar 62 continues to move, the drive rod 781 continues to move, allowing its other side first slope 782 to move along the other side second slope 785 on the protrusion 784, eventually separating. Driven by the reciprocating screw 61, the connecting bar 62 continues to move forward. When it moves to contact the second slope 785 on the next protrusion 784, the push rod 64 repeats the above action, allowing it to fully clean the inside of the sieve holes 3 on the sieve plate 2, thereby effectively preventing the sieve holes 3 from being blocked for a long time, which would affect the sieving efficiency and sieving effect of shiitake mushrooms.

[0053] Example 2:

[0054] Please see Figures 1-2 , Figures 6-7 When shiitake mushrooms are fed through the feeding device, the mushrooms tend to accumulate after being fed. When they are conveyed to the screen plate 2, the mushrooms will also accumulate on the surface of the screen plate 2, which will affect the screening efficiency of the mushrooms. Therefore, this embodiment provides a technical solution based on the above embodiment: it also includes an anti-slip conveyor belt 8, which is installed on the inner side of the feeding platform 4, and the conveying end position of the anti-slip conveyor belt 8 corresponds to the screen plate 2.

[0055] There are two support plates 9, which are symmetrically installed on both sides of the top of the feeding table 4. The top of the two support plates 9 is fixedly installed with mounting boxes 10.

[0056] An anti-stacking mechanism 11 is provided at the bottom of the mounting box 10. Two symmetrical guide grooves 111 are provided on the inner side of the mounting box 10. Two translation plates 112 are slidably connected to the inner side of the two guide grooves 111 respectively. A plastic curtain 113 is fixedly connected to the bottom of each of the two translation plates 112. The two translation plates 112 are staggered. A drive assembly 114 is provided inside the mounting box 10. The drive assembly 114 is used to drive the two translation plates 112 to perform alternating reciprocating motion.

[0057] Specifically, the actual thickness of the rubber curtain 113 can be selected based on the actual relative motion friction resistance between the mushrooms in direct contact with the anti-slip conveyor belt 8 and the anti-slip conveyor belt 8. This selection method can be obtained through simple testing, so that the bottom layer of mushrooms can push the bottom of the rubber curtain 113 during the conveying process, causing it to bend, without hindering the conveying of the bottom layer of mushrooms, and at the same time blocking the passage of the upper layer of mushrooms in the stacked state.

[0058] In this embodiment, the drive assembly 114 includes a disc 1141 rotatably connected to the inner side of the mounting box 10. Two linkage rods 1142 are rotatably connected to the surface of the disc 1141. The two linkage rods 1142 are rotatably connected to two translation plates 112 respectively. An electric cylinder 1143 is fixedly connected inside the mounting box 10. The telescopic end of the electric cylinder 1143 is fixedly connected to one of the translation plates 112.

[0059] Specifically, the two linkage rods 1142 are arranged in a centrally symmetrical manner, so that during the rotation of the disc 1141, the two translation plates 112 can move synchronously in opposite directions under the transmission action of the two linkage rods 1142.

[0060] Furthermore, the bottom surface of the rubber curtain 113 is flush with the upper surface of the anti-slip conveyor belt 8. When the anti-slip conveyor belt 8 moves the shiitake mushrooms that are in direct contact with it, the shiitake mushrooms can push the bottom of the rubber curtain 113 to move and bend. The sliding friction resistance between the shiitake mushrooms that are in direct contact with the anti-slip conveyor belt 8 is relatively large and greater than the pushing force of the bottom bending of the rubber curtain 113. When the shiitake mushrooms are stacked, the relative sliding friction resistance between the upper layer and the lower layer is relatively small. Therefore, under the obstruction of the rubber curtain 113, they can fall from the upper layer and be spread more evenly on the surface of the anti-slip conveyor belt 8 under the reciprocating motion of the rubber curtain 113. This makes the distribution of the shiitake mushrooms more loose when they are conveyed to the screen plate 2, which facilitates the shiitake mushroom screening process.

[0061] In use, the reciprocating extension and retraction of the telescopic end of the electric cylinder 1143 drives one side of the translation plate 112 to perform linear reciprocating motion. During the movement, the translation plate 112, under the transmission action of the linkage rod 1142 connected to it, can drive the disc 1141 to perform reciprocating rotation. Under the transmission action of the other linkage rod 1142, the rotation of the disc 1141 can drive the other side of the translation plate 112 to perform reciprocating motion in the opposite direction, so that the two translation plates 112 can perform synchronous motion in opposite directions. During the movement, the translation plate 112 can drive the rubber curtain 113 at its bottom to perform linear reciprocating motion, and push the stacked shiitake mushrooms to the side during the movement, thereby ensuring that the shiitake mushrooms conveyed to the screen plate 2 are relatively loosely distributed, which facilitates the rapid screening work.

[0062] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
