Description

[Detailed description of the invention] Industrial application field The present invention is a grass and rice straw forming machine that forms collected grass and rice straw into briquettes and cuts them into predetermined lengths. This invention relates to a discharging device that can smoothly and reliably discharge briquettes cut into strips parallel to the longitudinal direction.

Conventional technology Traditionally, grass and rice straw forming is a process in which dried grass and rice straw are collected in the field, compressed between multiple forming rollers, formed into cylindrical briquettes, and then cut into predetermined lengths and released. Various types of machines are known. The conventionally known pasture and rice straw forming machine is equipped with a briquette delivery guide tube whose lower half can be opened downward in the briquette delivery path, and when the briquettes are discharged, the lower half of the briquette delivery tube is opened downward to allow the briquettes to fall under their own weight.

Problems to be Solved by the Invention However, as described above, in the conventional method in which the lower half of the briquette delivery guide cylinder is opened and the briquettes after forming are allowed to fall under their own weight, a portion of the briquettes If the briquette gets caught in the delivery guide cylinder and becomes oblique, the briquette will be caught by it when the lower half is closed, resulting in the disadvantage that the briquette cannot be discharged smoothly.

Therefore, in view of the drawbacks of the conventional method, the present invention has been developed to provide a system in which, when discharging briquettes, the lower half of the briquette delivery guide tube is opened, and
The object of the present invention is to provide a discharging device for a grass and rice straw forming machine that can smoothly and reliably drop cut briquettes while keeping them parallel to the longitudinal direction by pressing both ends of the cut briquettes downward. be.

Means for Solving the Problems The present invention has the following technical means for achieving its purpose. That is, the discharge device in the grass and rice straw forming machine according to the present invention transfers the grass and rice straw raked and collected by the pick-up section installed at the front of the machine to the forming section at the rear of the machine and forms them into briquettes. In a pasture and rice straw forming machine that cuts briquettes into predetermined lengths, a briquette delivery guide cylinder is provided in the briquette delivery path of the forming section, and the lower half of the briquette delivery guide cylinder is attached to both ends of the upper half. The opening/closing arm is pivoted so that it can be opened and closed freely, and when the lower half is opened, the opening/closing arm intervenes in the upper half to press and drop the cut briquette parallel to the longitudinal direction, and when it is closed, the upper It is characterized in that a briquette extrusion arm that retreats outward from the half is integrally formed to extend.

Function The above technical means of the present invention works as follows.

That is, the briquettes formed in the forming section at the rear of the machine are transferred to the briquette delivery guide cylinder and cut into predetermined lengths in the process. Then, the lower half of the briquette delivery guide tube is opened by the opening/closing arms attached to both ends of the upper half, and the briquettes are dropped and released. Since the briquette push-out arms extended to press both ends of the briquette parallel to the longitudinal direction, the briquette is smoothly and reliably released. When the briquette is completely discharged, the lower half is closed again, but the briquette pushing arm is retracted out of the upper half and does not pinch the briquette at all.
