Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-Figure 6 As shown, the utility model provides the following technical solutions:

[0026] A mushroom screening and grading device comprises: a screening stand 1 and a hopper 2, wherein the hopper 2 is installed above one end of the screening stand 1, and when in use, mushrooms are introduced into the hopper 2, and the hopper 2 can evenly drop the mushrooms into the screening stand 1, and a collecting device is provided below the screening stand 1; side enclosures 3 are provided on both sides of the screening stand 1, and a sieve plate 4 arranged in the length direction of the screening stand 1 between the two side enclosures 3, and a mounting groove is provided in the side enclosure 3, and the sieve plate 4 is movably arranged in the mounting groove 5, and an elastic component is provided above the sieve plate 4 in the mounting groove 5;

[0027] The sieve plate 4 is provided with a screening part, and the screening part is provided with a primary screening part 6, a secondary screening part 7 and a tertiary screening part 8, and the sieve holes of the primary screening part 6, the secondary screening part 7 and the tertiary screening part 8 are small, medium and large respectively; the sieve plates 4 between the primary screening part 6 and the secondary screening part 7, the secondary screening part 7 and the tertiary screening part 8 are all provided as light plates, and the provision of the light plates facilitates the knocking device to perform better knocking vibration on the entire sieve plate 4;

[0028] A knocking device cooperating with the light plate is provided under the sieve plate 4, and the knocking device includes a rotating rod 901, a connecting rod 902, an impact ball 903 and a motor 904. One end of the connecting rod 902 is connected to the rotating rod 901, and the other end of the connecting rod 902 is connected to the impact ball 903. Both the connecting rod 902 and the impact ball 903 are made of rubber. The impact point of the impact ball 903 is the center of the light plate. The motor drives the rotating rod 901 to rotate. The knocking device is used in conjunction with the elastic component, which can effectively ensure the stability of the overall device.

[0029] The elastic component includes a plurality of springs and a support plate. The upper end of the spring 1201 is connected to the side enclosure 3, and the lower end of the spring 1201 is connected to the support plate 1202. The length of the support plate 1202 matches the side enclosure 3. The function of the support plate 1202 is to facilitate the installation of the screen plate 4. After the screen plate 4 is inserted through the installation groove 5, it can be directly inserted to the bottom due to the reduction of the front breaking tension.

[0030] A pushing device is installed above the sieve plate 4, and the pushing device includes a transmission chain 1001 arranged above the side enclosure 3, and the transmission chain 1001 is clamped on the rotating wheel, and the rotating wheel includes a driving wheel and a driven wheel, and the driving wheel is connected to the output shaft of the motor, and a plurality of push plates are connected to the transmission chain 1001, and the push plate 1002 is arranged in the width direction of the sieve plate 4, and a rubber soft plate 1003 is connected to the bottom of the push plate 1002, and the bottom of the rubber soft plate 1003 is connected along its length There are several pressing blocks 1004 arranged side by side in the direction, and the pressing blocks 1004 bulge toward the direction of the sieve plate 4 and touch the sieve plate 4. Since the rubber soft plate 1003 has good softness, it drives the push plate 1002 forward during the transmission process of the chain. When the push plate moves forward, the pressing blocks 1004 contact the sieve plate 4, which makes the rubber soft plate 1003 elastic. When the pressing blocks 1004 encounter the sieve holes, the elasticity releases the downward rebound force and presses down the sieve holes, which effectively avoids the phenomenon of the mushroom being stuck in the sieve holes.

[0031] The collecting device includes a plurality of collecting boxes and conveyor belts. Collecting boxes 1101 are matched and installed below the primary screening part 6, the secondary screening part 7 and the tertiary screening part 8. The left and right sides of the top of the collecting box 1101 are provided with downwardly inclined slide plates 1102. A channel with a size corresponding to the sieve holes is provided between the two slide plates 1102. A conveyor belt 1103 is provided below the channel. The closing position is provided in the middle of the conveyor belt. The downwardly inclined slide plates 1102 are provided on the left and right sides, which can better prevent the mushrooms from being damaged due to collision during the falling process. In addition, a conveyor belt is provided below the collecting box 1101, and the screened mushrooms can be directly transferred to the next production workshop without the need for manual secondary handling, thereby greatly improving the work efficiency.

[0032] When the device is in use, the sieve plate is inserted through the installation groove provided in the side enclosure. An elastic component is provided in the installation groove. The elastic component can not only effectively press the sieve plate, but also better reduce the knocking and shaking phenomenon of the knocking device on the overall device when it is working. After the sieve plate is installed, the mushrooms are poured into the hopper 2, and then the power is started. The mushrooms in the hopper 2 begin to fall evenly, and the mushrooms are pushed to the screening part through the pushing device. Since the sieve holes are arranged in the order of small, medium and large, the mushrooms are screened step by step and fall into the collecting box. In this process, in order to prevent the mushrooms from piling up and getting stuck in the sieve holes, the device uses the knocking device to continuously knock on the bottom of the sieve plate. The knocking device cooperates with the elastic component to better enhance the vibration amplitude of the sieve plate and better ensure the pass rate of mushrooms. After the mushroom grading is completed, the mushrooms fall onto the conveyor belt through the slide of the collecting box, and the conveyor belt drives the screened and graded mushrooms to enter the next workshop.
