Description

Technical Field

[0001] The utility model relates to the technical field of silkworm cocoon breeding, in particular to a mulberry leaf chopping device for silkworm breeding. Background Art

[0002] Silkworm farming has a long history in my country. Domestication of silkworms dates back to before the Xia Dynasty. Silkworms were selected from mulberry pests, creating the art of sericulture. Traditional sericulture is generally manual. With the continuous development of society, the sericulture industry has experienced rapid growth, and sericulture technology has gradually achieved modular and industrialized development. In existing technologies, older silkworms can be fed directly with whole mulberry leaves, which is simple to feed. However, for younger silkworms, the leaves generally need to be chopped up according to their specific growth conditions to facilitate feeding.

[0003] A Chinese utility model patent with publication number CN215582662U discloses a mulberry leaf chopper, which includes a chopping box, a rotatable feed hopper installed at the feed end of the chopping box, a first motor installed on the chopping box, a power output end of the first motor extending into the chopping box and installed with a cutting blade, a plug-in plate inserted at the discharge end of the chopping box, a bracket provided below the chopping box, a multi-stage screen installed on the bracket that is inclined corresponding to the discharge end of the chopping box, and a collection box provided below the multi-stage screen. The inclined multi-stage screen and the collection box cooperate to effectively screen chopped mulberry leaves of different sizes, which is convenient for the subsequent feeding of silkworms of different ages.

[0004] Regarding the above-mentioned related technologies, the inventors believe that the following defects exist: the screen of the above-mentioned device is installed on the bracket, so that after the screen filters the chopped mulberry leaves, some mulberry leaf fragments and juice will remain on the screen, which is inconvenient to clean. If this continues for a long time, the residue on the screen will easily breed bacteria. When the above-mentioned device is used again, the bacteria on the screen will adhere to the chopped mulberry leaf fragments, affecting the quality of the mulberry leaf fragments and the health of the silkworms.

[0038] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; it is obvious that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0039] like Figure 1-14As shown, the embodiment of the present application discloses a mulberry leaf chopping device for mulberry silkworm breeding, including a base frame 10, a mounting frame 12, a crushing assembly 20, a vibration frame 30, a drive assembly 40, and a fixed assembly 50. A plurality of collecting boxes 11 are arranged at intervals along the length direction of the base frame 10. The collecting boxes 11 are slidably arranged in the base frame 10 to facilitate the removal of the collecting boxes 11. A mounting frame 12 is provided on one side of the base frame 10, and a crushing barrel 13 is vertically arranged on the mounting frame 12 on the side above the base frame 10. The crushing assembly 20 is arranged in the crushing barrel 13 for chopping mulberry leaves. The vibration frame 30 is arranged between the base frame 10 and the crushing barrel 13. The vibration frame 30 is arranged to be tilted downward from one end adjacent to the crushing barrel 13 to the end adjacent to the base frame 10 away from the crushing barrel 13. The drive assembly 40 is provided on the base frame 10 for driving the vibration frame 30 to vibrate. A screen 32 is slidably mounted on the vibrating frame 30. The screen 32 is provided with a plurality of groups of mesh holes 323. The groups of mesh holes 323 gradually increase in size from the upper end of the side plate 301 to the lower end of the side plate 301. A fixing assembly 50 is mounted on the side plate 301 to fix the screen 32. Mulberry leaves are poured into the crushing drum 13. The crushing assembly 20 chops the mulberry leaves in the crushing drum 13. The chopped mulberry leaves fall from the lower end of the crushing drum 13 onto the screen 32. The driving assembly 40 drives the screen 32 to vibrate up and down, causing the mulberry leaves to fall into different collection boxes 11 according to the size of the fragments.

[0040] Specifically, the vibrating frame 30 includes two spaced-apart side panels 301 and a connecting rod 302 connecting the two side panels 301. A first chute 31 with an inward notch is provided on the inner surface of the side panels 301 along the length of the side panels 301. One end of the first chute 31 extends to the upper edge of the side panels 301 and the other end is located within the lower edge of the side panels 301. The screen 32 includes a screen frame 321 and a bottom plate 322. Mesh holes 323 are provided on the bottom plate 322. Ribs 33 are provided on the outer sides of the two side panels of the screen frame 321. The ribs 33 slide within the corresponding first chute 31, allowing the screen 32 to slide between the two first chute 31, ensuring the stability of the screen 32 sliding on the vibrating frame 30. A square hole 34 is provided horizontally on the side panels 301. The distance between the square hole 34 and the groove wall of the first chute 31 on the side away from the crushing drum 13 is consistent with the length of the rib 33. The square hole 34 is connected to the first chute 31. The fixing assembly 50 includes a square rod 51 that slides within the square hole 34. When the screen 32 is installed on the vibration frame 30, the side wall of the square rod 51 contacts the end of the protrusion 33, thereby clamping the screen 32. A receiving tube 52 is provided on the outside of the side panel 301, corresponding to the square hole 34. A baffle 53 connected to the square rod 51 is slidably provided within the receiving tube 52, allowing the baffle 53 and the square rod 51 to move synchronously. A circular hole 54 is provided at the bottom of the receiving tube 52. A round rod 55 connected to the baffle 53 is slidably provided within the circular hole 54, allowing the round rod 55, the baffle 53, and the square rod 51 to move synchronously. A first compression spring 56 is provided on the rod body of the round rod 55 located between the baffle 53 and the bottom of the accommodating tube 52. One end of the first compression spring 56 is connected to the baffle 53 and the other end is connected to the bottom of the accommodating tube 52. Pulling the round rod 55 drives the baffle 53 and the square rod 51 to move, so that the end of the square rod 51 is separated from the protruding strip 33, thereby removing the restriction on the screen 32 of the square rod 51, so that the screen 32 can be slid out from the vibration frame 30.

[0041] During installation, a second chute 35 is defined at the bottom of the first chute 31, near the square hole 34. The second chute 35 communicates with the square hole 34. A first slider 36 is provided on the protrusion 33, with the end of the first slider 36 flush with the rear end of the protrusion 33. A sliding hole is also defined along the wall of the second chute 35, extending along its length. A slide rod 57 is slidably disposed within the sliding hole, with a baffle 58 disposed at the outer end of the slide rod 57. When the protrusion 33 slides into the first chute 31, the first slider 36 contacts the baffle 58. When the screen 32 is installed, the baffle 58 contacts the first slider 36. A second compression spring 59 is sleeved on the slide rod 57, located between the baffle 58 and the wall of the second chute 35. One end of the second compression spring 59 is connected to the baffle 58, and the other end is connected to the wall of the second chute 35. This allows the first slider 36 to push the baffle 58 when the screen 32 is installed. The bottom of the second chute 35 is also provided with a third chute 37 along its length. The width of the third chute 37 is greater than that of the second chute 35. One side of the third chute 37 is connected to the square hole 34. A slide plate 38 connected to the baffle 58 is slidably provided in the third chute 37, so that during the installation of the screen 32, the baffle 58 is pushed to move, thereby driving the slide plate 38 to slide. In the initial state, the slide plate 38 blocks the square hole 34, the end of the square rod 51 is located in the square hole 34 and contacts the slide plate 38, and the first compression spring 56 is in a compressed state. When the screen 32 slides into the vibration frame 30, the protrusion 33 slides in the first chute 31, and the first slider 36 slides in the second chute 35, pushing the baffle 58 and driving the slide plate 38 to leave the square hole 34. When the screen 32 completely slides into the installation position, the slide plate 38 completely leaves the square hole 34, so that the first compression spring 56 is in a compressed state. A compression spring 56 loses its restriction and pushes the baffle 53 and the square rod 51, so that the side wall of the square rod 51 contacts the end of the protrusion 33, so that the screen 32 is fixed; during the movement of the baffle 58, the second compression spring 59 is compressed. When the screen 32 needs to be removed, the round rod 55 is pulled outward, and the second compression spring 59 loses its restriction and pushes the baffle 58 and the slide plate 38, thereby pushing the screen 32. The baffle 58 blocks the square hole 34 again, so that the screen 32 can slide out.

[0042] In the specific setting, the first support column 14 and the second support column 15 are spaced apart on both sides of the base frame 10 in the width direction. The first support column 14 is located below the crushing cylinder 13 and is higher than the second support column 15. The tops of the first support column 14 and the second support column 15 are both provided with vertically arranged uprights 16. A connecting block 39 is provided on the side plate 301, and a connecting hole is vertically opened on the connecting block 39. The connecting block 39 is slidably mounted on the upright 16 through the connecting hole to ensure the stability of the up and down vibration of the vibration frame 30.

[0043] The drive assembly 40 includes a rotating shaft 41 that is horizontally rotatably mounted on the base frame 10 and has a length perpendicular to the length of the base frame 10. Two cams 42 are spaced apart on the rotating shaft 41, each of which contacts the bottom of the two side plates 301. The rotating shaft 41 rotates to drive the cams 42. When the protruding portion of the cam 42 contacts the bottom of the side plate 301, the vibrating frame 30 is pushed upward. When the protruding portion of the cam 42 separates from the bottom of the side plate 301, the vibrating frame 30 descends under the action of gravity, causing the vibrating frame 30 to vibrate up and down, driving the screen 32 to vibrate up and down. A mounting base 43 is provided on the base frame 10. A drive motor 44 is horizontally mounted on the mounting base 43. A first pulley 45 is mounted on the output shaft of the drive motor 44. A second pulley 46 is mounted at the end of the rotating shaft 41. The first pulley 45 and the second pulley 46 are connected by a transmission belt 47. The first pulley 45 is driven to rotate by the drive motor 44, and the second pulley 46 is driven to rotate by the first transmission belt 47, thereby driving the rotating shaft 41 to rotate.

[0044] A top plate 17 is provided on the top of the vertical rod 16, and a third compression spring 18 is sleeved on the rod body of the vertical rod 16 between the top plate 17 and the connecting block 39. One end of the third compression spring 18 is connected to the connecting block 39 and the other end is connected to the top plate 17. When the cam 42 rotates, the protruding part of the cam 42 contacts the bottom of the side plate 301, pushing the vibration frame 30 upward, and the third compression spring 18 is compressed. When the protruding part of the cam 42 separates from the bottom of the side plate 301, the third compression spring 18 loses its restriction and pushes the vibration frame 30 downward, so that the vibration frame 30 and the screen 32 can be quickly reset, so that the up and down vibration effect of the screen 32 is better.

[0045] Specifically, the crushing assembly 20 includes a support frame 21 disposed within the crushing drum 13. A rotating shaft 22, coaxially arranged with the crushing drum 13, is vertically rotatably mounted on the support frame 21. A plurality of cutters 23 are mounted on the rotating shaft 22. Rotation of the rotating shaft 41 drives the cutters 23 to cut the mulberry leaves within the crushing drum 13. A drive shaft 24 is horizontally rotatably mounted on the mounting frame 12. A first bevel gear 25 is mounted at the lower end of the rotating shaft 22. A second bevel gear 26 is mounted on the drive shaft 24. The first bevel gear 25 meshes with the second bevel gear 26. Rotation of the drive shaft 24 drives the second bevel gear 26, thereby rotating the first bevel gear 25 and the rotating shaft 41. One end of the drive shaft 24 is connected to the output shaft of a drive motor 44. This allows a single drive motor 44 to simultaneously drive the cutters 23 and the vibrating frame 30. This design makes the entire mechanical device more efficient and compact, as a single power source is required to perform two key functions. This simplifies the mechanical structure and reduces costs and maintenance complexity. A protective cover 27 is also provided at the bottom of the support frame 21 to cover the first bevel gear 25 and the second bevel gear 26 to prevent chopped mulberry leaves from falling on the first bevel gear 25 and the second bevel gear 26 and affecting the engagement of the first bevel gear 25 and the second bevel gear 26.

[0046] The operating principle of a mulberry leaf chopping device for silkworm breeding in this embodiment is as follows: when mulberry leaves need to be chopped, the drive motor 44 is started first, and then the mulberry leaves are poured in from above the crushing cylinder 13. The drive motor 44 drives the drive shaft 24 and the first pulley 45 to rotate. The drive shaft 24 rotates, thereby driving the second bevel gear 26 to rotate, and then driving the first bevel gear 25, the rotating shaft 22, and the cutter 23 to rotate to chop the mulberry leaves in the crushing cylinder 13. The rotation of the first pulley 45 drives the second pulley 46 to rotate, thereby driving the rotating shaft 41 and the cam 42 to rotate, so that the vibration frame 30 vibrates up and down, driving the screen 32 to vibrate up and down, and the chopped mulberry leaves fall onto the screen 32 from the lower side of the crushing cylinder 13, so that the mulberry leaves fall into different collection boxes 11 according to the size of the fragments. After the shredding is completed, the round rod 55 is pulled outward, driving the baffle 53 and the square rod 51 to move, and the square rod 51 is separated from the protrusion 33. The second compression spring 59 loses its restraint, pushing the baffle 58 and the slide 38, thereby pushing the screen 32. The baffle 58 blocks the square hole 34 again, allowing the screen 32 to slide out for cleaning. When the round rod 55 is pulled outward, the first compression spring 56 is compressed. When the screen 32 is installed, the screen 32 slides into the vibration frame 30, the protrusion 33 slides in the first chute 31, and the first slide 36 slides in the second chute 35, pushing the baffle 58 and driving the slide 38 to leave the square hole 34. When the screen 32 is fully slid into the installation position, the slide 38 completely leaves the square hole 34, causing the first compression spring 56 to lose its restraint, pushing the baffle 53 and the square rod 51, so that the side wall of the square rod 51 contacts the end of the protrusion 33, so that the screen 32 is fixed.
