Peanut combine harvesting metal wire screen

Abstract

The invention relates to a peanut combine harvesting metal wire screen, and belongs to the technical field of agricultural harvesting devices. An input end an output end of a rectangular screen frame of the screen are provided with a front hanging plate and a rear hanging plate vertical to a transport direction separately; the front hanging plate and the rear hanging plate are provided with flanged hanging sides of which the sections are convex separately; a group of metal wire holes and a wire clamping gap are uniformly distributed in the flanged hanging side of the front hanging plate; a corresponding tensioning device is arranged at the lower part of the front wire clamping gap; a group of wire clamping bridges are uniformly distributed on the flanged hanging side of the rear hanging plate; after two ends of the metal wire are turned from two sides of the wire clamping bridges separately, one end is fixed in the metal wire holes and the other end passes through the wire clamping gap and then is connected with the corresponding tensioning device. By adopting the peanut combine harvesting metal wire screen, the effective screen surface is increased; vine hanging and blocking are effectively avoided through the self-excited vibration effect of the metal wire, scattering of a material layer to screen out large impurities is facilitated, feeding of peanut is facilitated, congestion is avoided and the screening effect and efficiency are significantly improved.

Description

technical field [0001] The invention relates to a wire sieve, in particular to a wire sieve for combined peanut half-feeding and harvesting, and belongs to the technical field of agricultural harvesting processing devices. Background technique [0002] Peanut half-feed combined harvesting fruit picking parts usually contain about 18% to 25% of soil with a certain humidity, about 70% to 80% of fresh peanuts, and impurities such as broken branches, broken seedlings, residual film, leaves, etc. These materials Common access to the cleaning components of the peanut combine harvester. According to the applicant's knowledge, for a long time, the combined harvest of peanuts has been cleaned by hole sieves, and the idea of ​​improving the screening efficiency has been focused on how to improve the screening mechanism. Some recent innovations can be found in Chinese patent documents such as application numbers 201120244113.8 and 201410181268.X. Although the prior art occasionally h...

Problems solved by technology

Although the prior art occasionally has screens of other structures besides hole screens (such as the primary vibrating screen for peanut pickers disclosed in Chinese Patent Application No. 201110331394.5), they all rely entirely on the vibration of the power source, so in practice, not only High energy consumption, and because of the small holes, it is easy to get stuck in impurities such as stems and leaves, resulting in hanging seedlings and blockage, affecting the screening effect and efficiency
