Description

Special roller for lifting and throwing ridge-furrow straws

Technical Field

The utility model belongs to agricultural machinery, and mainly relates to an operation assembly assembled on a straw crushing and returning machine or a combined soil preparation machine.

Background

The straw crushing and returning to the field is one of effective ways and methods for implementing strict straw field burning law regulations, avoiding environmental pollution, effectively utilizing the fertility of the fertilizer and improving the soil structure. In order to meet and adapt to the requirements of straw crushing and returning operation, various types of straw crushing and returning machines or combined soil preparation machines have been developed and applied, and the level of mechanization operation and the straw returning rate are improved. However, due to the defects in the aspect of structural design, the existing machine is only suitable for straw crushing operation in the horizontal farming agricultural areas, is not suitable for the ridge farming agricultural areas, and has poor straw crushing effect in furrows during operation in the ridge farming areas. In view of the above problem, the applicant has developed a milling cutter roll having milling cutters with long furrows and milling cutters with short ridges and lands mounted on the same cutter shaft at intervals, but found in practical use that the milling cutter roll has the problems of high power consumption, high milling cutter wear speed, short service life and high operation cost

Disclosure of Invention

The utility model aims at solving the problems existing in the prior art, combining the practical use requirement of the straw crushing and returning operation in the current ridge culture area, researching and designing a special roller for throwing ridge furrows and straws, and achieving the purposes of meeting the use requirement of the straw crushing and returning operation in the ridge culture area, good quality of the straw crushing operation and high efficiency.

The utility model discloses a basic design is: the roller shaft is rotatably arranged on the two hanging plates which are oppositely arranged, the roller shaft is positioned between the two hanging plates which are oppositely arranged, the shaft sleeve is sleeved on the roller shaft in a radial positioning way, the circumferential direction can be rotated and the axial direction can be moved, the disc is fixedly arranged on the shaft sleeve, the two end faces of the disc are respectively provided with spring teeth, the steel wire rope is inserted on the disc, the steel wire rope positioned at the outer part of the two end faces of the disc is bent and pressed by the U-shaped fixing clamping group and is fixed on the two end faces of the disc into a whole, the roller shaft is provided with a ditch adjusting hole, the shaft sleeve is fixed on the roller shaft by the insertion matching of the adjusting locking pin arranged on the shaft sleeve and the ditch.

The utility model discloses a spring tooth and wire rope are picked up the straw in the furrow in succession and are thrown, smash the operation for the straw of configuration rear side and create good crushing condition for smashing the rotor, provide sufficient feeding straw volume, have simple structure, reasonable, the furrow straw is picked up and is thrown effectual, play throw rate height, characteristics that the suitability is strong, smash still field and joint soil preparation operation for ridge culture agricultural technology area straw and provide technical support.

FIG. 1 is a schematic view of the general structure of a furrow straw throwing special roll;

FIG. 2 is a partial sectional view taken along line A-A of FIG. 1;

fig. 3 is a sectional view taken along line B-B of fig. 2.

Description of part numbers in the figures:

1. the device comprises hanging plates, 2, a roll shaft, 3, a ditch adjusting hole, 4, an adjusting locking pin, 5, a shaft sleeve, 6, spring teeth, 7, a steel wire rope, 8, a U-shaped fixing clamping group, 9, a disc, 10 and a driving wheel.

Detailed Description

The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. A roller shaft 2 is rotatably installed on two hanging plates 1 which are oppositely configured, the roller shaft 2 is positioned between the two hanging plates 1 which are oppositely configured, a shaft sleeve 5 is sleeved on the position, between the two hanging plates 1, of the roller shaft 2 in a radial positioning mode, the position is rotatable in the circumferential direction and movable in the axial direction, a disc 9 is fixedly installed on the shaft sleeve 5, spring teeth 6 are respectively installed on two end faces of the disc 9 in a matching mode, a steel wire rope 7 is inserted on the disc 9, the steel wire rope 7 positioned on the outer portion of the two end faces of the disc 9 is bent and pressed and fixed on the two end faces of the disc 9 into a whole through a U-shaped fixing clamping group 8, a ditch adjusting hole 3 is formed in the roller shaft 2, the shaft sleeve 5 is fixed on the roller shaft 2 through the insertion matching of an adjusting locking pin 4 which is installed on the shaft sleeve 5 and.

When in use, the hanging plate 1 is used for installing the roller on the front side part of the straw crushing knife roller of the straw crushing returning machine or the combined soil preparation machine, and the disc 9 is positioned at the longitudinal central line part of the furrow. During operation, the output rotary power drives the spring teeth 6 and the steel wire rope 7 to rotate through the driving wheel 10, the roll shaft 2, the adjusting locking pin 4, the shaft sleeve 5 and the disc 9 in sequence, straws in furrows are picked up and thrown up, and the picked-up and thrown-up straws are smashed by the straw smashing knife roll rotating at the rear side in the flying process, so that operation is completed.

The regulation stop pin 4 is extracted from the ditch regulation hole 3 on the roller shaft 2, the shaft sleeve 5 is axially moved on the roller shaft 2, the operation requirement of the furrow operation with different spacing distance sizes can be adapted and satisfied, and the operation application range of the utility model is enlarged.
