Description

Straw smashing device of cotton stalk pulling smashing machine

Technical Field

The utility model relates to a straw smashing device of a cotton stalk pulling smashing machine.

Background

The cotton planting scale of China shows a situation of increasing year by year in recent years, the first cotton production country and the first consumption country around the world already exist, the total yield and the unit yield are at the top of the world, the process of cotton straw recovery is an important component of the agricultural production link, and the straw recovery and returning to the field after cotton harvesting is favorable for increasing the fertility of soil, reducing the using amount of chemical fertilizers, improving the structure of the soil, realizing the yield increase of crops and simultaneously reducing the environmental pollution caused by burning the straws;

the cotton straw crude fiber content is high, the cotton straw crude fiber content is the condition of being used as animal feed after production and processing, large-area comprehensive utilization of the cotton straw can be guaranteed, efficient utilization of resources is achieved, meanwhile, the cheap straw feed can save high feeding economic cost for breeding industry, and economic benefits are increased for farmers and feeding industry.

The cotton straw that current cotton straw crushing operation machine carried the auger will be carried is directly sent into cutting reducing mechanism, cuts reducing mechanism and cuts the crushing to cotton straw afterwards, then throws out through throwing the board and reaches the purpose of retrieving and returning the field.

Present pull out cotton stalk rubbing crusher's straw reducing mechanism inhomogeneous, incomplete to the smashing of straw, can only carry out coarse crushing to cotton stalk, and the straw thickness after smashing differs with big or small degree, is unfavorable for the stem corruption of smashing still field on the one hand, and the straw after being unfavorable for smashing when on the other hand is retrieved outwards throws out, smashes the in-process simultaneously and takes place blocking phenomenon easily and lead to crushing efficiency not high, influences normal operating mass and efficiency.

Disclosure of Invention

An object of the utility model is to provide a pull out cotton stalk rubbing crusher's straw reducing mechanism, the device reliable operation, power are powerful, crushing ability is strong, can carry out fine crushing to cotton stalk, make by the better recycle of kibbling cotton stalk ability and still field, the pair roller adopts the initiative rotation centre gripping form, can be to the effectual extrusion centre gripping of cotton stalk and force backward transport, avoided blocking phenomenon's emergence simultaneously again, improved kibbling efficiency widely.

The utility model aims at realizing the straw smashing device, which comprises a frame, wherein an auger conveying roller is arranged in the front part of the frame, a double-roller clamping and extruding conveying mechanism is horizontally arranged in the middle part of the frame at the rear part of the auger conveying roller from top to bottom, the double-roller clamping and extruding conveying mechanism comprises a lower clamping roller, an upper clamping roller, a bearing seat, a sliding bearing seat, an adjusting bolt and a tensioning spring, the lower clamping roller is arranged on the frame through the bearing seat, the upper clamping roller is arranged on the frame through the sliding bearing seat, the adjusting bolt and the tensioning spring are arranged between the sliding bearing seat and the frame, and rectangular convex edges are uniformly distributed on the axial roller surfaces of the upper and lower clamping rollers; a cutting knife crushing mechanism is arranged in the rear part of the frame and comprises a rotary roller, a cutting knife, a fixing bolt and a cutting knife bracket; the cutting knife brackets are uniformly distributed on the peripheral surface of the rotary drum at intervals, the top surfaces of the cutting knife brackets are high in front and low in back, and the cutting knives are obliquely arranged on the cutting knife brackets through fixing bolts; the throwing mechanism is arranged above the cutting knife crushing mechanism and comprises a rotary throwing plate and a throwing port.

The utility model discloses an operating principle carries out the collection of cotton straw and carries backward through carrying the auger, and the cotton straw that carries the auger is carried to lower grip roll afterwards and last grip roll extrudees the centre gripping and further carries backward, and the cutting knife of cutting knife device carries out crushing operation to the cotton straw that two pairs of rollers were carried this moment, and the cotton straw after smashing is thrown the board and is thrown out from throwing the mouth through throwing.

The fixed part is used for supporting and fixing all parts except the rack and comprises the rack; the auger conveying part is used for collecting and conveying the cotton straws backwards and comprises a conveying auger roller; the double-pair-roller clamping extrusion conveying part is used for extruding, clamping and further conveying the cotton straws conveyed by the conveying auger backwards, and comprises a lower clamping roller, an upper clamping roller, a bearing seat, a sliding bearing seat, an adjusting bolt and a tensioning spring; the cutting knife crushing part is used for crushing cotton straws conveyed by the double pairs of rollers and comprises a rotary drum, a cutting knife, a fixing bolt and a cutting knife bracket; the throwing part is used for throwing the crushed cotton straws out through the throwing port and comprises a throwing plate and a throwing port. The utility model discloses adding double-phase roller pair rotatory to cotton straw between carrying auger and cutting knife reducing mechanism and extruding the centre gripping to carry backward, two have the bead to the roller circumference can increase the dynamics to cotton straw extrusion centre gripping, have improved the granularity and the homogeneity that the cotton straw was smashed to the cutting knife through setting up two roller pairs.
