Description

Grass collecting box for grass discharging port of combine harvester Technical Field The utility model relates to the technical field of harvesters, in particular to a grass collecting box for a grass discharging port of a combine harvester. Background A combine harvester is a device for harvesting crops (e.g., rice, barley, wheat, beans, etc.), threshing the crops, and screening the grains (grains, particles) therefrom as they travel in a farm field. However, when the existing combine harvester is used for harvesting crops, the harvested grains are collected in a storage unit of the harvester, but straws and the like in the storage unit are scattered into the field through a straw discharging port along with the movement of the harvester, when the straws and the like are required to be utilized, people are required to collect the straws and the like, but the scattered straws are difficult to collect and have low efficiency. In view of the above, the present inventors have specifically devised a grass collecting box for a grass discharging port of a combine harvester, which is produced by this scheme. Disclosure of utility model In order to solve the problems, the technical scheme of the utility model is as follows: The utility model provides a combine arranges grass mouth with collection grass case, includes the box, one side of box is the opening setting and with combine arranges grass mouth swing joint, the box bottom is the opening setting and is equipped with rotatable grass collecting plate, the grass collecting plate is equipped with the axis of rotation, the axis of rotation is located the bottom that the box is close harvester one side and is connected with the box rotation, traction pulley, support bar and traction tube are installed in proper order to the box lateral wall from the top down, support bar one end and box threaded connection, its other end and traction pulley threaded connection, the inside balancing weight that moves about that is equipped with of traction tube, axis of rotation, traction pulley and balancing weight pass through the haulage rope and connect gradually. Preferably, the grass collecting plate is arranged in a fence shape, and comprises a plurality of grass collecting rods which are welded on the rotating shaft. Preferably, the rotation shaft comprises a traction part and a rotation part, the traction part and the rotation part are integrally formed, bearing holes are formed in two ends of the bottom of the box body, the rotation part penetrates through the bearing holes to be rotationally connected with the box body, and the traction part is connected with a traction pulley and a balancing weight through a traction rope. Preferably, the distance between the grass collecting rods is 3cm-7cm. Preferably, the distance between a plurality of grass collecting rods is 5cm. Preferably, the side wall of the box body is provided with a supporting plate, the supporting plate is in threaded connection with the supporting plate, and the traction pipe is welded at the lower end of the supporting plate. Preferably, a traction ring is arranged at the end part of the traction part and the top of the balancing weight, and the traction rope penetrates through the traction ring to connect the traction part, the traction pulley and the balancing weight. Preferably, the top of the box body is provided with a mounting empty groove, and the mounting empty groove is attached to the upper edge of the grass discharging opening. The technical scheme provided by the utility model has the following beneficial effects: 1. According to the utility model, the balancing weight, the traction rope, the traction pulley, the grass collecting plate and the like are arranged on the grass collecting box, the grass collecting box is connected with the grass discharging port of the harvester, and when the harvester is used for harvesting, straws, grass and the like continuously enter the grass collecting box, and when the weight of the harvester reaches a certain value, the gravity provided by the balancing weight is insufficient to keep the grass collecting plate closed, so that the grass collecting plate is opened to enable the straws and the like to be gathered and piled on the ground, and then the balancing weight is used for reducing the grass collecting plate, so that the straws and the like can be automatically collected and piled during harvesting, and the collection efficiency of staff is improved. 2. The weight of each straw pile is approximately equal through the arrangement of the balancing weights, and the collection is more convenient. Drawings The accompanying drawings, which are included to provide a further understanding of the utility model and are incorporated in and constitute a part of this specification, illustrate embodiments of the utility model and together with the description serve to explain the utility model and do not constitute a limitation on the utility model.
