Description

TECHNICAL FIELD

[0001] The utility model relates to a corn harvester is with anti -peeling roll bolt loosening and break mechanism. BACKGROUND

[0002] The existing corn harvester peeling roller often faces a thorny problem in the use process: due to the inevitable shaking and vibration of the machine in the running process, the mechanical movement often leads to the loosening or even breakage of the bolt of the bearing seat fixed on the peeling roller. Once the bolt is loose or broken, the stability and working efficiency of the peeling roller will be greatly reduced, which will not only affect the harvesting efficiency of corn, but also may cause damage to other parts of the machine, increase the maintenance cost and time. In addition, the loose or broken bolt may also become a safety hazard, threatening the safety of the operator. Therefore, how to solve the problem of bolt loosening and breakage caused by machine shaking during the use of the peeling roller has become the key to improving the performance and reliability of the corn harvester. We need to continuously explore and improve in the process of design, manufacture and use to ensure the stability and durability of the peeling roller and improve the overall performance of the corn harvester. SUMMARY

[0003] The utility model aims at solving above prior art's insufficient, provide a kind of corn harvester is with anti -peeling roll bolt loosening and break mechanism.

[0004] A kind of corn harvester is with anti -peeling roll bolt loosening and break mechanism, including bearing seat, rack, at least one bearing mounting hole, multiple bolt holes, positioning protrusion are equipped on the bearing seat, the rack front frame plate, rear frame plate, multiple peeling rollers are equipped between front frame plate and rear frame plate, the both ends of peeling roller are connected in the bearing mounting hole of bearing seat by bearing,

[0005] The upper end surface of front frame plate and rear frame plate is provided with through slot, and the front end surface is provided with multiple threaded holes, the bearing seat is connected with rack, positioning protrusion is clamped in through slot, bolt hole and threaded hole correspond, and bolt is arranged in it, and is locked by nut.

[0006] Further, the number of bolt holes is three.

[0007] Further, the positioning protrusion is of rectangular structure.

[0008] Further, the positioning protrusion is located between three bolt holes.

[0009] Further, the number of bearing mounting holes is two.

[0010] Further, bearing mounting hole is located above positioning protrusion, and three bolt holes are located on both sides and below positioning protrusion respectively.

[0011] Beneficial effects: Compared with the prior art, this new invention uses the combination of positioning protrusions and through grooves to avoid the peeling roller being stressed by the fixing bolts on the bearing seat during operation, which would cause the bolts to loosen or even break due to excessive stress, thus reducing maintenance time.
