Problems solved by technology

[0003] The inventor believes that the current common crop stalk conveying device is limited by the crop planting mode and has poor versatility. It can only be used for corn, cotton stalks, sunflower stalks and other crops planted in flat crops, but cannot be used for crop stalks planted in ridges such as sweet potatoes and potatoes. Conveying of stalks; the stalk clamping parts are constrained by the diameter, size and shape of the stalks of the crops, and need to be replaced when conveying different crops; the height of the stalk conveying device is fixed and cannot be adjusted, and the cutting test of different cutting heights of the stalks cannot be realized

Abstract

The invention discloses a crop stalk conveying device for a test bed, belongs to the technical field of agricultural machinery, and can realize stalk conveying operation of rhizome crops with various planting modes and different stalk diameter sizes. The crop stalk conveying device for the test bed comprises a conveying belt, strip-shaped bulges and clamping mechanisms, wherein connecting positions used for being connected with the strip-shaped bulges or the clamping mechanisms are formed on the surface of the conveying belt, and a plurality of connecting positions are arranged in the width and/or length direction of the conveying belt; the strip-shaped bulges imitate the shape of a soil ridge and are detachably installed on a conveying belt baffle, and the extending direction of the strip-shaped bulges is the same as the conveying direction of the conveying belt; the clamping mechanisms used for clamping crops are mounted at the connecting positions and/or the strip-shaped bulges of the conveying belt; and the clamping crack direction of the clamping mechanisms mounted on the top surfaces of the strip-shaped bulges is the same as the conveying direction of the conveying belt, and the crops are provided with a plurality of clamping positions in the clamping crack direction.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a crop stalk conveying device for a test bench. Background technique [0002] The crop stalk cutting test bench can simulate the field operation performance test of the machine or parts, which can overcome the conditions of unstable field test environment and high test cost. Through multiple tests, a wealth of test data can be obtained to provide a theoretical basis for the development of machines and parts , has the advantages of convenient operation and low test cost. The stalk conveying device in the test bench can transport the crop stalks to the cutting parts at different speeds under the power drive, and combine with other devices of the test bench to complete the performance test and experiment of various operations. [0003] The inventor believes that the current common crop stalk conveying device is limited by the crop planting mode and has po...
