DETAILED DESCRIPTION

[0023] The above and other technical contents, features and functions of the present invention are described in detail below with reference to the attached Figures 1 to 3 The details of the embodiments will be clearly presented. The contents mentioned in the following embodiments are all based on the drawings in the specification.

[0024] Various exemplary embodiments of the present utility model will be described below with reference to the accompanying drawings.

[0025] The utility model discloses a mushroom conveyor for screening out impurities, comprising a vibrating screen box 1, a partition board 2 and a conveyor belt 3. The vibrating screen box 1 and the conveyor belt 3 are respectively placed in two workshops, which are separated by the partition board 2. A discharging port is provided at one end of the vibrating screen box 1, and a discharging port is provided on the partition board 2. The two discharging ports are arranged in a corresponding and matching manner. A discharging hopper 5 with a certain inclination is arranged at the discharging port of the vibrating screen box 1, which is convenient for discharging mushrooms. The discharging hopper 5 passes through the partition board 2 and is arranged on the other side of the vibrating screen box 1. The interior of the vibrating screen box 1 is a cavity with an opening at the upper end. A vibrating screen 4 with a certain inclination is placed in the vibrating screen box 1, which is convenient for the mushrooms to move to the discharging port. A vibrating motor is installed in the vibrating screen box 1, which is used for vibrating and screening the mushrooms on the vibrating screen 4. Impurities such as dust, platycodon and small particles falling to the bottom are removed by the vibrating screen 4. A side door is provided on the side wall of the vibrating screen box 1, which is convenient for cleaning the vibrating screen box 1 below the vibrating screen 4. A plurality of hopper holes 6 are provided at the bottom of the discharge hopper 5. When the mushrooms pass through the discharge hopper 5, the amount of mushrooms on the discharge hopper 5 is less than the amount of mushrooms in the vibration screen box 1. Therefore, vibration screening is performed again here, and the impurities are discharged through the hopper holes 6. A cylindrical screen 7 with a certain inclination is installed at the end of the discharge port. The cylindrical screen 7 can rotate. After the mushrooms come out of the discharge hopper 5, they enter the cylindrical screen 7. After the cylindrical screen 7 is rotated and screened for impurities, the impurities fall out of the cylindrical screen 7 and the mushrooms fall onto the magnet roller 9. The cylindrical screen 7 cooperates with a blower mechanism on one side. The blower mechanism blows air toward the cylindrical screen 7 to blow away the light impurities from the mesh or the two ends of the cylindrical screen 7. The mushrooms that fall onto the magnet roller 9 are adsorbed and processed by the magnet roller 9, such as small pieces of metal such as screws and patches. The magnet roller 9 is installed on the conveying frame plate 8. Multiple magnet rollers 9 can be arranged at intervals. The magnet roller 9 drives the small pieces of metal impurities to rotate, which can increase the adsorption area of ​​the magnet roller 9.

[0026] Among them, the distances between the vibrating screen 4, the hopper hole 6, the mesh of the cylindrical screen 7, and the magnet roller 9 are all smaller than the size of the mushrooms to prevent the mushrooms from falling therethrough.

[0027] Pour the mushrooms onto the vibrating screen 4 in the vibrating screen box 1, and first pass through the vibration screening of the vibrating screen 4, the amount of mushrooms entering the discharge hopper 5 will be reduced, and then pass through the hopper hole 6 on the discharge hopper 5 for screening, and then the amount of mushrooms entering the cylindrical screen 7 will become less again, and then pass through the cylindrical screen 7 for screening, and then cooperate with the blower mechanism to make the screening effect better, and finally pass through the magnet roller 9 for screening. After multiple screenings, dust, platycodon, metal and other impurities in the mushrooms can be removed, and the removal efficiency is high, which ensures the quality and taste of the final product of the mushrooms.

The cylindrical screen motor 15 is fixed on the screen plate 10. A cylindrical ring 12 is fixedly sleeved on the other end of the cylindrical screen 7. A power-boosting wheel 16 is placed at the lower end of the cylindrical ring 12. The power-boosting wheel 16 is fixed on the screen plate 10. The power-boosting wheel 16 is in rolling contact with the cylindrical ring 12, so that when the cylindrical screen 7 rotates, the power-boosting wheel 16 also rotates. The power-boosting wheel 16 provides support for the cylindrical screen 7 and facilitates the rotation of the cylindrical screen 7.

[0029] The cylindrical screen motor 15 is turned on to coaxially drive the cylindrical pinion 14 to rotate, and then the cylindrical outer gear 13 is engaged to rotate, and the cylindrical screen 7 rotates under the support of the power-assisting wheel 16 and the cylindrical screen ring 11 to achieve the impurity removal of the mushrooms.

[0030] Furthermore, in order to achieve the quantity and progress of mushroom screening, two vertical L-shaped discharge slide rails 17 are fixed on the partition board 2. The discharge slide rails 17 are placed above the discharge hopper 5. A baffle plate 18 is slidably installed in the discharge slide rails 17. By sliding the baffle plate 18 up and down, the outlet height of the discharge hopper 5 can be controlled. A limiting bolt is installed on the baffle plate 18. After adjusting the height of the baffle plate 18, the limiting bolt is rotated to fix the baffle plate 18 to achieve control of the discharge amount of mushrooms.

[0033] After the conveying motor 25 is started, the transmission belt roller is driven to rotate through the pulley 24 and the first roller 22, thereby driving the conveyor belt 3 to convey normally. At the same time, the plurality of second rollers 23 are driven to rotate through the pulley 24 and the belt, thereby driving the magnet roller 9 to rotate normally. Firstly, it can absorb metal impurities, and secondly, it can drive the mushrooms forward to the conveyor belt 3.

[0034] Furthermore, when the magnet roller 9 adsorbs a large amount of impurity metal, it will affect the adsorption force of the magnet roller 9. A vertical support plate 26 is provided at the lower end of the magnet roller 9. The support plate 26 is fixed on the screen plate 10. A plurality of scrapers 27 are fixed to the upper end of the support plate 26. The scrapers 27 are respectively placed under each magnet roller 9. When the magnet roller 9 rotates, the scrapers 27 are used to scrape off the metal impurities adsorbed on the surface of the magnet roller 9 to ensure the adsorption force of the magnet roller 9. The scrapers 27 are hard plastic scrapers.

[0035] Furthermore, in order to realize normal blowing of the hair dryer mechanism, the hair dryer mechanism includes a rectangular hair dryer shell 28, one end of the hair dryer shell 28 is fixed to the partition board 2 through a shell rod 31, the interior of the rectangular shell is a cavity, and an air inlet is provided on the rear side.

[0037] Working principle:

[0038] Pour the mushrooms into the vibration screen box 1, and through the cooperation of the vibration motor and the vibration screen 4, the mushrooms are subjected to the first-level impurity removal treatment, and then through the cooperation of the discharge hopper 5, the baffle plate 18, and the soft leather curtain 20, a small amount of mushrooms are slowly shaken off and enter the cylindrical screen 7, and then the cylindrical screen motor 15 drives the cylindrical pinion 14 to engage the cylindrical outer gear 13 to rotate, and then cooperate with the blower mechanism to carry out the third-level impurity removal treatment, and finally the slowly falling mushrooms enter the magnet roller 9 for the fourth impurity removal treatment, and finally enter the subsequent process through the conveyor belt 3.
