Description

Technical Field

[0001] The invention relates to the technical field of silkworm breeding equipment, and in particular to a cutting box of a mulberry leaf cutter. Background Art

[0002] At present, in the process of mulberry silkworm breeding, in the process of quantitatively feeding mulberry leaves to young silkworms or making mulberry leaf tea, mulberry leaves are cut into small shapes of uniform size. Especially in the process of preparing feed for young silkworms, it is best to cut the mulberry leaves into small strips of mulberry leaves with basically the same size and small differences in vein distribution.

[0003] The Chinese invention patent application with patent application number 202110759047.6 discloses a high-speed leaf cutter, which uses a cutting box as a material cutting device and is directly installed in the equipment. The cutting opening is formed by installing equally spaced rollers in the cutting box and cooperating with the pressing shaft to cut the material into strips to ensure the cutting effect. Although this structure achieves the effect of easy disassembly, installation and maintenance of the rollers and rotary cutters, the cutters of this structure rotate at high speed during the leaf cutting process, which will roll part of the mulberry leaf stems or mulberry leaf branches between the cutters or between the cutters and the cutting box. The long-term accumulation of mulberry leaf stems or mulberry leaf branches will squeeze the cutter, which may cause the cutter to bend and deform, and may even cause the cutter to interfere with the cutting box and cause a knife jumping accident, which not only affects the leaf cutting effect, but also affects the life of the cutter, and even poses a safety hazard. In summary, the existing high-speed leaf cutters still have defects and need to be further improved. Summary of the invention

[0004] The present invention provides a cutting box of a mulberry leaf cutter, which can comb cutters and allow mulberry leaves or mulberry leaf branches to be discharged smoothly during the cutting process, thereby preventing mulberry leaf stems or mulberry leaf branches from being accumulated between the cutters for a long time and causing the cutters to be deformed due to stress, thereby ensuring the leaf cutting effect, increasing the life of the cutters and reducing safety hazards of the equipment.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is:

[0006] A cutting box of a mulberry leaf cutter comprises a cutting roller body and a mounting box; the cutting roller body is rotatably connected to the mounting box; a plurality of cutting knives distributed at equal intervals are arranged on the outer peripheral wall of the cutting roller body, and a plurality of long avoidance holes are arranged at the bottom of the mounting box, and every two of the cutting knives are located in one of the long avoidance holes; a comb tooth is arranged in each of the long avoidance holes, and each of the comb teeth is located between the corresponding two cutting knives; each of the long avoidance holes extends to one end of the mounting box, and a discharge hole is provided at one end of the long avoidance hole corresponding to the position of the mounting box; one end of the comb tooth is fixedly connected to the mounting box, and the other end of the comb tooth is located at the discharge hole.

[0007] Further, the installation box body includes two installation plates and a cutter baffle; the two installation plates are arranged in parallel at intervals, one of the installation plates is fixedly connected to one side of the cutter baffle, and the other installation plate is fixedly connected to the other side of the cutter baffle; the cutting hob body is rotatably connected to the two installation plates; the strip avoidance holes are opened on the cutter baffle along the radial direction of the cutter.

[0008] Further, the cutter baffle is in an L-shaped structure, and each long strip avoidance hole extends from the end of the L-shaped horizontal end of the cutter baffle to the L-shaped vertical end, and each long strip avoidance hole penetrates through to the L-shaped vertical end of the cutter baffle to form the discharge hole; the discharge hole extends along the end of the L-shaped vertical end of the cutter baffle, so that the cross-sectional structure of the long strip avoidance hole is in an L shape.

[0009] Further, one end of each comb tooth is fixedly connected to the L-shaped horizontal end of the cutter baffle, and the other end of each comb tooth is suspended and faces a corresponding discharge hole.

[0010] Further, a U-shaped installation groove is opened on each installation plate, and the two U-shaped installation grooves are arranged in alignment; both ends of the cutting hob body are respectively installed in a corresponding U-shaped installation groove through a bearing seat.

[0011] Further, a plurality of threaded holes are also opened on each installation plate, and the bearing seat is fixedly connected to the threaded holes through a plurality of bolts.

[0012] Further, a plurality of connecting ears are also fixedly connected to each installation plate.

[0013] The beneficial effects of the present invention are as follows:

[0014] In the present invention, during the cutting process, the comb teeth block most of the mulberry leaf stems or branches from getting stuck between the cutters, and when the cutters rotate at high speed, the comb teeth comb and guide the small part of the mulberry leaf stems or branches that are stuck on the cutters, so that the mulberry leaf stems or branches are discharged from the discharge holes, thereby enabling the cutters to operate smoothly, avoiding the mulberry leaf stems or branches from being stacked on the cutters for a long time and being bent and deformed under force, ensuring the cutting effect of the cutters, prolonging the service life of the cutters, and reducing the potential safety hazards of the equipment.
