Bark shredder

Abstract

The invention discloses a bark shredder. The bark shredder comprises a rack, a feeding bucket, a shredding roller device, a discharging opening, a motor and a speed reducer, wherein the feeding bucket, the shredding roller device, the discharging opening, the motor and the speed reducer are mounted on the rack; the feeding bucket is located above the shredding roller device, and the discharging opening is formed below the shredding roller device; the motor and the speed reducer are in transmission connection through a belt wheel and a belt; the speed reducer is in transmission connection with the shredding roller device; the shredding roller device comprises two roller shafts, and a plurality of fluted discs which are uniformly arranged at intervals on the two roller shafts in a sleeving manner; the fluted discs on the two roller shafts are staggered to each other; the end parts at the same side of the two roller shafts are in transmission connection through gears mounted on the two roller shafts in an engaging manner; one roller shaft is in transmission connection with the speed reducer; two ends of the two roller shafts are respectively fixedly mounted on the rack through an assembled bearing and a bearing block. According to the bark shredder, the structural design is reasonable, and the operation is easy; the shredded materials are proper and uniform in particle size; in addition, the bark shredder can be used for shredding and processing ores, wood, leaves, feeds and the like, and has a relatively wide applicable scope.

Description

technical field [0001] The invention belongs to the technical field of crushing devices, in particular to a bark crusher. Background technique [0002] As we all know, in the planting of orchids, the plant material is a very critical factor that affects the quality of the flowers. When planting orchids, because the oak bark that has been soft and decomposed for more than six or seven years has a balanced nutrition and a moderate pH value, it is clean and free of bacteria. Good air permeability, good drainage, soft, light, durable and moisturizing, vigorous hair roots, easy flowering of flowers and plants, quick potting, no burnt tips of art plants and flowers, good gloss of leaves, vigorous growth of seedlings, and cold resistance in winter, etc., so Usually, the particles made of oak bark by crushing are used as the plant material for orchid cultivation, but due to the limited resources of soft and decomposed oak bark more than six or seven years old, barks such as qinggang...

[0002] As we all know, in the planting of orchids, the plant material is a very critical factor that affects the quality of the flowers. When planting orchids, because the oak bark that has been soft and decomposed for more than six or seven years has a balanced nutrition and a moderate pH value, it is clean and free of bacteria. Good air permeability, good drainage, soft, light, durable and moisturizing, vigorous hair roots, easy flowering of flowers and plants, quick potting, no burnt tips of art plants and flowers, good gloss of leaves, vigorous growth of seedlings, and cold resistance in winter, etc., so Usually, the particles made of oak bark by crushing are used as the plant material for orchid cultivation, but due to the limited resources of soft and decomposed oak bark more than six or seven years old, barks such as qinggang and pine are also used as raw materials. Long-term studies have found that the oak bark particles used in orchid planting must be uniform in size and moderate in size, and must not damage its internal structure, otherwise, if the particles are too large or powdery, they will not be suitable for the growth of orchids.

[0003] At this stage, for the crushing of oak, qinggang and other bark, hammer crushers are mostly used to crush the bark to form granules. However, the crusher with this structure will make the bark form more powder after crushing. , the size of the particles is also uneven, and the particle structure is destroyed, which causes a serious waste of raw materials and increases the production cost
