Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides the following features: from a first conveyance device to a second conveyance device;
This relates to a grain culm conveying device for conveying grain culms such as soybeans.

Generally, in this type of grain culm conveying device, for example, the first conveying device is provided with a first endless band made of a chain and a peg for guiding the grain culm along the first endless band. , the stock part of the grain culm is held and conveyed, and the head part is passed along the rotating handling drum of the threshing part to perform threshing. A second conveying device is provided, which includes an endless band and a rod for guiding the grain stems along the second endless band, and transports the grain stems out of the machine. In the conventional grain culm conveying device, the gap between the first endless band and the clamping rod is the same as the gap between the second endless band and the receiving rod, and is provided as close as possible. That is, when transporting rice culms, this configuration was suitable as a means for ensuring reliable transport, since the grain culms have a small diameter and are soft. However, when transporting grain culms of legumes such as soybeans, the diameter of the grain culm is large and hard, so if the gap between the endless belt and the clamping rod is too narrow in the first transport device, the grain culm may break. Conveyance may be hindered, and if the gap between the endless band and the rod of the second conveyance device is made large, the clamping force becomes insufficient and conveyance cannot be carried out smoothly.

In the present invention, the gap between the first endless band and the rod is replaced by the second endless band.
By providing a larger gap than the gap between the endless band and the rod, the grain culms of legumes will not break when being transported, and the transportation will be carried out reliably and smoothly. Hereinafter, one embodiment of the present invention will be described in detail using the drawings.

1 to 4, reference numeral 1 denotes a threshing section of a pulse threshing device, in which a handling cylinder (not shown) is rotatably provided. 3 is a first conveying device that conveys the grain culms of the legumes supplied to the supply port 4 to the threshing section 1;
The grain is threshed when passing through a handling drum (not shown). Its configuration is as follows. That is, 5 is a first endless belt which rotates around sprockets (not shown) provided at the front and rear positions, and is composed of a chain with a protrusion 6, and a peg 7 provided along the lower part. The grain culms are held between them and transported backwards. Reference numeral 9 denotes a support rod fixed to the clamping rod 7, and is supported by the support base 11 so as to be slidable in the vertical direction. Reference numeral 13 denotes a bullet that presses the lever 7 upward. The lever 7 is the first endless belt 5
The upper limit position is regulated by a stopper (not shown) so as to provide a gap 15 of a predetermined size between the two. Reference numeral 17 denotes a second conveying device for picking up grain culms from the first conveying device 3, conveying them, and discharging them to the outside, and is configured as follows. That is, 1
Reference numeral 9 denotes a support rod which is fixed to a bracket 21 fixed to the support stand 11 with screws 23 and 25 so that its horizontal position can be freely adjusted; and 27 is a rotatably supported support piece 29 fixed to the end of the support rod 19. 31 is a support piece that is slidably fitted in the middle of the support rod 19 and is adjustable and fixed by a bolt 33; 35 is a pulley rotatably supported on the support piece 31; 37, 39; 45 and 47 are slotted holes 49 and 51 provided in the sliding pieces 37 and 39, respectively. Brackets 57 and 59 are rotatably supported on the lower ends of the brackets 45 and 47, respectively, through which brackets 57 and 59 are fixed in vertical positions with bolts 53 and 55, respectively. A second endless belt 61 rotates around the pulley 27, pulley 35, roller 57, and roller 59, and is formed of a rubber belt having a protrusion 63 on its outer circumferential surface. Reference numeral 65 denotes a rod provided along the lower part of the second endless band 61, one end of which is fixed to the clamping rod 7, and a gap 67 is provided between it and the second endless band 61. The gap portion 15 is provided in a larger clamping gap than the gap portion 67.

In the above configuration, the grain stems supplied from the supply port 4 are conveyed while being clamped between the first endless band 5 and the clamping rod 7, and pass through a handling cylinder (not shown) in the threshing section 1. The grain culms after threshing are carried from the first endless belt 5 to the second endless belt 61, are conveyed while being held between the receiving rods 65, and are transported from the end of the receiving rods 65 to the outside of the machine. This is what is discharged.

As described above, the present invention provides the first conveying device 3 equipped with the pinning rod 7 for guiding the grain culm along the first endless belt 5 of the supply port 4 of the threshing section 1 for threshing pulses, The second endless band 6 on the terminal end side of this first conveying device 3
A second conveying device 17 equipped with a receiving rod 65 for guiding the grain culm along the grain culm is provided, and the grain culm being threshed is transferred from the first conveying device 3 to the second conveying device 17 by pinching and conveying the grain culm during threshing. In the threshing machine for conveying grain culms, the gap 15 between the first endless band 5 and the clamping rod 7 is replaced by the gap between the second endless band 61 and the receiving rod 65. Since this is a grain culm conveying device characterized by having a gap larger than the part 67 so as to loosely pinch and transfer the culm, the threshing part 1
In the first conveying device 3 for threshing, even if the clamping force of the grain culm is loosened, the grain culm is reliably transferred during threshing while utilizing the resistance caused by the tensile force of threshing due to the hardness of the grain culm. This can reduce breakage and breakage due to this clamping force, and the grain culms threshed in the threshing section 1 and carried to the second conveying device 17 are not subjected to strong culm tension as caused by the threshing action. Because it is not affected by the action, the culm will not break or break, and even if it breaks easily, it will not affect the threshing action, so it should be held relatively firmly and transported smoothly. It is something that can be done.

It should be noted that the present invention is not limited to the above-mentioned embodiments, but can be implemented in other embodiments as well.

5 and 6 show a conventional grain culm conveying device, and the same reference numerals as those in FIGS. 1 to 4 indicate the same components.
