An automatic opening and closing grass box

Abstract

The invention relates to an automatic opening and closing grass collecting box, which comprises four side plates and a rectangular bottom plate, the bottom of the side plates is rotatably connected to the edge of the bottom plate; the opposite side plates are a group of side plates; the feature is that , also includes a compression cylinder and a power transmission mechanism; the compression cylinder and the power transmission mechanism are located at the bottom of the base plate; the power transmission mechanism includes a rotating member, a push plate and a pull rope; one end of the rotating member passes through the The stay ropes are respectively connected to two sets of side plates, and the other end is connected to the expansion rod of the compression cylinder through the push plate; Pull force is applied to the side panels; the compression cylinder drives the push plate to pull the rotating member to rotate, and the pulling force of the pull cord on the side panels on both sides disappears; the grass collection box is automatically opened and closed through the control of the compression cylinder.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to an automatic opening and closing grass collecting box. Background technique [0002] The technology in the field of corn harvesters is becoming more and more mature. In actual production, corn harvesters not only harvest corn ears, but also collect corn stalks at the same time. The collected corn stalks can be fed to cattle and sheep, increasing user income. [0003] The existing corn harvester is not equipped with a special grass collecting box, and cannot collect corn stalks simultaneously during the corn harvesting process. Because the existing grass collecting box cannot be opened and closed automatically, and the volume is too large, when it is installed on the corn harvester, it will hinder the operation of the corn harvester, resulting in a significant reduction in the efficiency of corn harvesting and increasing production costs. [0004] However, using the existin...

AI Technical Summary

Problems solved by technology

[0003] The existing corn harvester is not equipped with a dedicated grass collection box, and cannot collect corn stalks at the same time during the corn harvesting process

Since the existing grass collection box cannot be opened and closed automatically, and the volume is too large, when it is installed on the corn harvester, it will hinder the operation of the corn harvester, resulting in a significant reduction in the efficiency of corn harvesting and increased production costs

[0004] However, using the existing automatic opening and closing device with the motor and connecting rod, due to the complex structure of the transmission mechanism, a large number of parts need to be equipped, resulting in an increase in the overall weight of the corn harvester, which will also affect the operation of the corn harvester
