Description

TECHNICAL FIELD

[0001] The utility model relates to agricultural processing technical field, concretely is a straw rubbing silk device. BACKGROUND

[0002] Crop straw is an important biological resource, if mishandling, not only will cause the waste of resources, will cause the great damage to the environment more. Therefore how to do the conversion work of crop straw, has become the agricultural problem that urgently to be solved. Most of the straw raw materials need to carry out corresponding crushing processing etc. before development and utilization, only when the rubbing silk crushing of biomass meets certain size and requirement, can make full preparation for subsequent biomass research and utilization. Therefore, the research of straw rubbing silk crusher has important significance to the development and utilization of biomass energy.

[0003] Although China has developed straw rubbing silk crushing technology for many years, the types and crushing methods of rubbing silk crusher are various, but the feed form processed by the existing rubbing silk crushing equipment is too crushed or forms granular shape, and cannot form a relatively regular strip shape, which is not conducive to subsequent transportation and feeding of livestock, therefore, improving the forming capacity of rubbing silk crushing makes the processed material form a relatively regular strip to meet the needs of various straw crushing and rubbing. SUMMARY

[0004] The utility model aims at providing a straw rubbing silk device, adopts full -automatic feeding system, and adopts multi -knife type cutting principle, can according to the demand with various straw and fresh straw powder form ideal demand, and this machine mainly aims at green, wet straw, the crushing degree thickness adjustment. Material is transported to the rubbing silk machine shell in the feeding hopper, and the material rubbing silk is thrown out by the high -speed rotating blade and rubbing strip interaction. The form of straw material rubbing silk is improved, and the production efficiency is greatly improved, and the production cost is saved.

[0005] In order to achieve the above object, the technical scheme of the utility model is as follows:

[0006] A kind of straw rubbing silk device, feeding hopper is arranged above shell, discharge port is arranged below shell, rubbing silk bearing is arranged on both sides of shell, rubbing silk bearing supports the both ends of rotating shaft, the part of rotating shaft in shell interior is installed blade trolley, a plurality of groups of blades are hinged and installed on blade trolley, and a plurality of rubbing strips are arranged on the circumference of shell inner wall.

[0007] The rubbing strip is cylindrical and is welded in the inner cavity of the shell, and the length direction of the steel bar is perpendicular to the rotating direction of the blade; when the blade rotating frame is driven to rotate, the blade group hinged on the rotating frame is thrown radially due to the centrifugal force, and the straw material in the feeding hopper is cut and crushed, at the same time, the straw material is turned in the inner cavity of the shell, the speed of the material in the outer layer is reduced by being touched and blocked by the rubbing strip, the speed of the material in the inner layer keeps synchronous with the blade, and the straw in the inner and outer layers is entangled and rubbed to form a strip shape, and the powder crushed material can be wrapped in the strip material.

[0008] The rotating power of the rotating shaft is derived from the rubbing wire motor, the rubbing wire motor is installed on the support frame and is driven through a belt pulley and a belt.

[0009] A feeder is arranged in the feeding hopper, the feeder is a rotating paddle structure, the rotating shaft of the paddle is supported by bearings on both sides, a feeder motor is installed on the support frame and is driven through a belt pulley and a belt.

[0010] In order to balance the feeding speed, the material is stored in the feeding hopper, the feeder rotates uniformly to feed the straw into the rubbing wire shell cavity uniformly, and the rubbing uniformity is prevented from being poor.

[0011] The upper part of the feeding hopper is the end of the horizontal conveying belt.

[0012] Advantages of the utility model

[0013] The utility model utilizes the principle that the high-speed rotating multi-blade cutting and rubbing strip interact with each other, can crush and rub various straws and fresh straws into ideal material forms according to requirements, and can meet the needs of subsequent transportation and feeding.

[0014] Compared with the fixed star-shaped blade of the traditional rubbing wire machine, the plurality of hinged blades can effectively prevent the rubbing wire cavity from being blocked due to excessive resistance, reduce the abrasion of the blade and save the production cost.

[0015] The type and quantity of the blade in the blade component can be selected according to different rubbing wire materials, and the sawtooth-shaped blade, the non-sawtooth-shaped blade or the mixture thereof can be selected and used alone, so that the utility model has a wide range of applications.

[0016] The feeder of the utility model can balance the feeding uniformity of the rubbing wire, prevent the blockage or insufficient feeding caused by the fluctuation of the material feeding, and improve the uniformity of the rubbing wire form of the outlet straw. DRAWINGS
