Stable cutting and conveying mechanism of straw harvester

Abstract

The invention discloses a stable cutting and conveying mechanism of a straw harvester. The stable cutting and conveying mechanism comprises a trolley body, a cutting wheel and an electric roller; the left side of the upper end of the trolley body is fixedly connected to a hydraulic cylinder I and a fixing plate, the upper end of the hydraulic cylinder I is connected to a hydraulic cylinder II, the right end of the hydraulic cylinder II is in bolted connection with a sliding block, a sliding fixation groove with an opening in the upper end is formed in the left side of the fixing plate, and the sliding block is connected inside the sliding fixation groove in a sliding mode; and the left end of the hydraulic cylinder II is fixedly connected to a roller bracket, the electric roller is installed on the roller bracket, a roller surface of the electric roller is fixedly connected to a plurality of clamping grooves, and rubber patting plates are connected inside the clamping grooves in a clamped mode. According to the stable cutting and conveying mechanism, in the rotation process of the electric roller, the rubber patting plates exert backward pushing force from above straw in the patting process, and therefore the straw can be pushed backwards and fall onto a conveying belt smoothly, and then the transferring process can be completed. The stable cutting and conveying mechanism has the advantages that cutting and conveying are stable and reliable, the straw is prevented from being missed, the overall structure is simple and transformation is convenient, can be applied to most existing straw harvesters and is convenient to use and high in reliability and flexibility.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a stable mowing mechanism of a straw harvester. Background technique [0002] After corn and other crops are harvested, there are often a large amount of straw left in the field. Generally, small fields will be cleaned and removed by burning, while medium and large farming bases will generally be harvested by straw harvesters for secondary use. To reduce environmental pollution, most of the existing straw harvester cutting and transporting mechanisms use the cutting wheel and the transport belt to cooperate. The cutting wheel cuts the straw and the straw falls on the transport belt to complete the cutting and collection process. Forward movement exerts a forward thrust on the base of the straw, and most of the straw will fall backwards on the transport belt, but the falling direction of the straw is not stable. In the actual harvesting process, it often happens that the straw cannot be ...

[0002] After corn and other crops are harvested, there are often a large amount of straw left in the field. Generally, small fields will be cleaned and removed by burning, while medium and large farming bases will generally be harvested by straw harvesters for secondary use. To reduce environmental pollution, most of the existing straw harvester cutting and transporting mechanisms use the cutting wheel and the transport belt to cooperate. The cutting wheel cuts the straw and the straw falls on the transport belt to complete the cutting and collection process. Forward movement exerts a forward thrust on the base of the straw, and most of the straw will fall backwards on the transport belt, but the falling direction of the straw is not stable. In the actual harvesting process, it often happens that the straw cannot be collected by the transport belt and then harvested The phenomenon that the wheels of the machine are overwhelmed. After harvesting, there are often a large number of straws that slip through the net in the field. These straws need to be collected manually, which is very troublesome. avoid the above from happening
