Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a helical grain lifting device, and can be used in a grain transfer unit of a combine harvester, a threshing machine, a huller, etc. that transfers grain, etc.

Problems to be Solved by the Invention In a device for processing grains, grains or Since dust and the like tend to accumulate and remain, it is necessary to remove this and clean it. This invention aims to facilitate the cleaning operation of this helical grain lifting device.

Means for Solving the Problem This invention provides an opening/closing lid 4 of a terminal end opening 3 of a helical tube 2 for transferring grains, and an opening/closing lid 4 for an opening 3 at the terminal end of a helical tube 2 for transferring grains, and a mechanism that communicates with the helical tube 2 to receive and move the grains upward. The structure of the helical grain frying device is such that the opening/closing lid 8 of the lower end opening 7 of five grain helical tubes 6 for frying the grains can be opened and closed in conjunction with each other.

Functions and Effects of the Invention When grains are fried, the grains transferred to the terminal end of the helical tube 2 by the rotation of the helical 1 in the helical tube 2 are transferred to the helical 5 in the helical tube 6 for frying. The grains are taken over by the rotation of the helical tube 6, and the grains are fried inside the helical tube 6. After the work is finished, there are no grains, dust, etc. left in the joint between the helical tubes 2 and 6. Therefore, when opening/closing lids 4, 8 that close these openings 3, 7, these lids 4, 8 can be opened and closed in conjunction with each other, so both lids 4, 8 are almost closed. It is easy to operate because it opens with the same operation at the same time, and the remaining particles and dust inside are cleaned and taken out from the openings 3 and 7, and when the cleaning is finished, the openings 3 and 7 are closed again with the lids 4 and 8. Since the grain transfer part between the terminal end of the helical tube 2 and the lower end of the fried grain helical tube 6 is a part where grains are likely to stagnate, the openings 3 and 7 provided therein are interlocked. By opening and closing almost simultaneously, cleaning can be easily performed.

Embodiment In the illustrated example, the helical transfer gutter is provided at the bottom of the grain sorting device of the threshing machine, etc., and is configured to receive grains flowing down from the upper side and take them out and transfer them to the outside of the machine by rotating the helix 1. One end of the transfer gutter extends outward from the body to form a helical tube 2, and this helix 1 extends from the transfer gutter portion and is positioned within the helical tube 2. 9 is this spiral 1
The shaft is a shaft, and one end is bearing the outer end of the helical cylinder 2. The opening 3 is located at the lower side of the helical tube 2, and the opening/closing lid 4 is provided with a hinge 10 so as to be openable and closable.

The grain frying spiral cylinder 6 communicates with the terminal end of the spiral cylinder 2 through a communication port 11, and the spiral cylinder 5 is mounted on a shaft 12 and is erected upward, with a discharge port provided at the upper end for use in grain tanks, bag openings, etc. The structure is designed to make you look forward to it. Spiral 5
The lower end of the shaft 12 bears on the bottom of this helical cylinder 6,
The shaft 13 is interlocked with a gear, and a chain 14 is used to interlock and rotate between the sprocket of the shaft 13 and the sprocket at the end of the helical shaft 9. The opening 7 is opened at the lower end of the helical tube 6 and located at the outer periphery of the lower end rotation area of the helical 5.
5 so that it can be rotated to open and close.

The bracket 16 to which the opening/closing lid 8 is attached is integrally constructed with the helical tube 2 attached to the outer end of the body 17, and attaches and holds the helical tube 6 to the body 17.

A leaf spring 18 is fixed to the opening/closing lid 8, and an operating lever 19 is attached to the tip of the leaf spring 18 so as to be rotatable only in the lateral direction. 19, the opening/closing lid 8 can be biased in the closing direction by the elastic force of the leaf spring 18.
Further, both ends of a coiled spring 21 having an intermediate portion wound are engaged between the outside of the opening/closing lid 8 and the outside of the opening/closing lid 4, so that the spring 21 is elastically moved against the opening/closing lid 8 in the closing direction. The elastic force of the plate spring 18 is set to be stronger than the elastic force of the coiled spring 21. The opening/closing operation of both the opening/closing lids 8, 4 is performed by the spring 1 mentioned above.
In addition to 8 and 21, other mechanisms may be used in conjunction with each other.

The grains for removal processed in the machine body 17 are received by the helical 1 gutter, taken out by the rotation of the helical 1 into the helical cylinder 2, and transferred to the fried grain helical cylinder 6 through the communication port 11. The grains are fried and transferred through the helical tube 6 by the rotation of the helical 5. At this time, the operating lever 19 is in the solid line position in FIG. The opening/closing lid 4 is forced to close the opening 3 through the openings 3 and 7 to prevent the transferred grains from leaking out from these openings 3 and 7.

When opening the openings 3 and 7, remove the operating lever 19 from the engaging portion 20, the leaf spring 18 will loosen, and the opening/closing lid 8 will be loosened.
rotates around the shaft 15 to open the opening 7, and by opening the opening/closing lid 8, the coil spring 21 is loosened to rotate the opening/closing lid 4 around the hinge 10 to open the opening 7. 7 to remove residual grains, dust, etc. inside the helical tube 2 and the lower end of the helical tube 6.
