AI Technical Summary
Existing silkworm cocoon screening and grading devices are unable to efficiently separate impurities and shriveled or rotten cocoons from the cocoons, resulting in a decline in cocoon quality.
A silkworm cocoon screening and grading device was designed, which includes a support frame, grading components and auxiliary components. The device uses a screen rod, an arc plate and a motor-driven gear system to grade and screen the silkworm cocoons. Impurities and shriveled cocoons are screened off into the collection box through the screening holes and the guide plate, while plump cocoons roll into the guide box. The motor-driven gear system moves the filter frame left and right to perform screening.
This technology enables efficient grading of silkworm cocoons, effectively separating impurities and shriveled or rotten cocoons, thus improving work efficiency and ensuring the quality of silkworm cocoons.

Detailed Implementation
[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0025] like Figure 1 As shown, a silkworm cocoon screening and grading device includes a support frame 1, a grading component 2 is fixedly connected to the upper surface of the support frame 1, an auxiliary component 3 is fixedly connected to the rear of the grading component 2, a U-shaped plate 4 is fixedly connected to the lower surface of the middle part of the support frame 1, and a collection box 5 is slidably connected to the inner wall of the U-shaped plate 4.
[0026] First, the silkworm cocoons are poured onto the upper surface of the grading component 2. Then, under the action of the grading component 2, the silkworm cocoons are filtered. Impurities and shriveled or rotten cocoons are filtered into the collection box 5, while the remaining silkworm cocoons are sent to the auxiliary component 3 by the staff for sorting.
[0027] like Figure 2 As shown, the auxiliary component 3 includes a fixed shell 31, the lower surface of which is fixedly connected to the upper surface of the support frame 1. A partition 32 is fixedly connected to the rear of the fixed shell 31. Two material collection frames 34 are fixedly connected to the upper surface of the rear part of the support frame 1, and the two material collection frames 34 are located on the left and right sides of the partition 32 respectively. Guide boxes 33 are fixedly connected to both the left and right sides of the fixed frame 21, and the two guide boxes 33 are located above the two material collection frames 34. The bottom of the inner wall of the two material collection frames 34 is inclined towards the two material collection frames 34.
[0028] The partition 32 divides the rear part of the support frame 1 into two spaces. Then, the two guide boxes 33 allow the sorted cocoons to be moved to the top of the two collection frames 34 for grading.
[0029] like Figure 3 As shown, the grading component 2 includes a fixed frame 21, the lower surface of the fixed frame 21 is fixedly connected to the upper surface of the support frame 1, a filter frame 23 is attached to the upper surface of the middle part of the fixed frame 21, and a plurality of screen rods 25 are fixedly connected to the inner wall of the filter frame 23; screening holes are provided between the plurality of screen rods 25, and four arc-shaped plates 26 are fixedly connected to the upper surface of the plurality of screen rods 25; a guide plate 22 is fixedly connected to the inner wall of the fixed frame 21 and the guide plate 22 is located below the filter frame 23.
[0030] Through the action of several sieve bars 25, impurities and shriveled cocoons in the silkworm cocoons can be sieved off, and then moved into the collection box 5 under the guidance of the guide plate 22, so as to facilitate centralized cleaning. The arc plate 26 allows the full cocoons to roll down, so as to facilitate the workers to quickly distinguish and grade them, thereby improving work efficiency.
[0031] like Figure 4 As shown, guide rods 24 are slidably connected to the inner cavities of the front and rear parts of the filter frame 23, and the left and right sides of the two guide rods 24 are fixedly connected to the opposite surfaces of the left and right parts of the fixed frame 21, respectively.
[0032] The guide rod 24 enables the filter frame 23 to move stably left and right inside the fixed frame 21, thus playing a guiding role.
[0033] like Figure 5 As shown, a motor 35 is fixedly connected to the inner cavity of the fixed shell 31. A gear 36 is fixedly connected to the output end of the motor 35. Gears 37 mesh on both the upper and lower sides of the outer wall of the gear 36. The outer walls of the rear parts of the two gears 37 are rotatably connected to the inner cavity of the fixed shell 31. Arc gears 38 are fixedly connected to the front of the two gears 37. A toothed plate 39 meshes on the lower surface of the upper arc gear 38 and is located between the two arc gears 38. A T-shaped connecting plate 310 is fixedly connected to the front of the toothed plate 39. The front of the T-shaped connecting plate 310 is fixedly connected to the rear of the filter frame 23.
[0034] The motor 35 drives the first gear 36 to rotate the two second gears 37 simultaneously. Under the action of the two second gears 37, the two arc gears 38 rotate. Since the two arc gears 38 face the same direction, they can take turns pushing the toothed plate 39. Under the action of the T-shaped connecting plate 310, the toothed plate 39 moves back and forth, thereby allowing the filter frame 23 to screen the silkworm cocoons inside, so that impurities and shriveled cocoons can be screened out.
[0035] The two arc-shaped gears 38 face the same direction, and the outer wall of the rear part of the T-shaped connecting plate 310 is slidably connected to the inner cavity of the fixed shell 31;
[0036] The T-shaped connecting plate 310 enables the toothed plate 39 to stably move the filter frame 23, thus facilitating screening.
[0037] The working principle of this utility model is as follows: First, the silkworm cocoons are poured onto the upper surface of several sieve rods 25. Then, through the action of the motor 35, the gear 1 36 drives two gears 2 37 to rotate simultaneously. Under the action of the two gears 2 37, the two arc gears 38 rotate. Since the two arc gears 38 face the same direction, they can alternately push the toothed plate 39. Thus, under the action of the T-shaped connecting plate 310, the filter frame 23 moves back and forth. Through the action of several sieve rods 25, impurities and shriveled cocoons in the silkworm cocoons can be screened off. Then, under the guidance of the guide plate 22, they move into the inside of the collection box 5. Next, through the action of the arc plate 26, the full silkworm cocoons can roll down. At this time, the workers can pick the full and large silkworm cocoons into one of the guide boxes 33, and then pick the less full and small silkworm cocoons into the filter frame 23 on the other side, thus completing the grading.
