Description

Technical Field

[0001] The utility model relates to the technical field of harvesting and baling machines, in particular to a harvesting and baling machine for fresh-edible corn dry plants. Background Art

[0002] A harvester baler is an agricultural machine, a mechanical device used to harvest and bundle crops. Its workflow usually includes four steps: mowing, conveying, compressing, and tying. At present, in the process of harvesting fresh corn stems, a harvester baler is needed to harvest and bundle fresh corn stems.

[0003] The invention patent with authorization announcement number CN111802088B discloses a continuous packaging type corn stalk harvester and baler, which comprises a main frame, a traction rod is arranged in front of the main frame, a guide wheel is arranged below the main frame, a load-bearing wheel is arranged on the rear side of the guide wheel, a shell is arranged on the outer side of the main frame, and a side mounting port is arranged on the outer side of the shell; a picking box is arranged on the front side of the main frame, a picking roller is arranged on the inner side of the picking box, and a picking tooth is arranged on the outer side of the picking roller, a horizontal auger is arranged on the rear side of the picking box, a vertical auger is arranged on the rear side of the picking box, and the top of the vertical auger is arranged on the upper side of the picking box. A middle auger is arranged at the end; the compression box is used as a straw storage compression chamber, and the compression push plate inside the compression box can compress the crushed straw, and a telescopic feeding cylinder is arranged on the compression push plate, and the telescopic feeding cylinder can fill the straw into the compression box through the central feeding port, and the central feeding port can move with the compression push plate, so as to carry out the filling and compression work, so as to ensure that the compression rate is consistent with the feeding rate, and improve the efficiency and density of the straw compression, and at the same time, a cylindrical folding packaging bag is arranged in the compression box, and the straw can be directly filled into the bag for compression packaging, and can be continuously packaged, which is beneficial to improving the processing efficiency of the straw without the assistance of additional coating devices.

[0004] Although the continuous packaging corn stalk harvester and baler is conducive to improving the efficiency of stalk processing, the device still has the following problems in actual use: the picking box in the device will inevitably absorb some foreign matter into the equipment during the continuous picking process, which will cause failures and require maintenance by staff. Although the existing picking box design takes maintenance needs into consideration and can be flipped to a certain extent for maintenance personnel to check and repair, the limited flipping angle makes maintenance work quite difficult. In view of this, we propose a harvester and baler for fresh corn dry plants. Utility Model Content
