A reaping device and a threshing device for threshing the harvested cereals are configured to continuously harvest and thresh uncut cereals in the field and collect the grains (for example, Patent Documents) 1 or Patent Document 2).

Currently, biomass fuels are being put to practical use as part of solutions to energy and environmental problems. The use of rice straw as a biomass fuel, soft cellulose, is being studied for practical use. For example, since the rice straw after the grain is collected can be used, even if rice straw is used as the biomass fuel, it is possible to avoid the problem of food problems. However, when collecting rice straw after the collection of grains (general waste discharged from the combine into the field cuts), the rice straw is generally collected with a tractor front gripper or fork type work machine. There were a method of carrying on a truck and a method of collecting rice straw with a self-propelled roll baler to form a bale. In those methods, the operation | work which collects rice straw is required separately from the grain harvesting operation | work which collects a grain. Improvement of workability for collecting and transporting rice straw is desired. Therefore, a technology that can improve the workability of collecting and transporting rice straw has been developed. For example, a tank for storing the waste fine fragments is communicated with the waste fine fragment discharge port of the waste cutter mounted on the combine via a blower for sending the waste fine fragments, and the tank is collected while collecting the grains. There is a technique for collecting excretion (see Patent Document 1). Moreover, the technique (refer patent document 2) which mounts the roll baler which forms a bale by excretion in a combine, and forms a bale while collecting a grain is also well-known.

As shown by the phantom lines in FIG. 6, a waste support base 223 that supports the bag-like waste storage body 87 in a downward opening posture is provided. The waste support platform 223 is disposed at a position higher than the bottom of the waste tank 85 and adjacent to the right side of the waste cutter 35 (rear of the grain tank 7). The waste outlet side of the waste duct 93 is extended from the lower surface side to the upper surface side of the waste support base 223. The waste outlet side of the waste duct 93 is opened upward on the upper surface side of the waste support base 223. The evacuation outlet 93 of the evacuation duct 93 is inserted into the evacuation container 87 in the downward opening posture of the upper surface of the evacuation support base 223.

  With the above-described configuration, the waste conveyed by the spring conveyor 91 (the waste conveying conveyor mechanism 86) is sent into the waste container 87 in the downward opening posture from the feeding end side of the spring conveyor 91. The waste is loosely compressed in the waste storage body 87 by the waste feed resistance on the waste outlet side of the waste duct 93 opened upward (self-gravity of the waste outside the outlet of the waste duct 93). While filling. By increasing the clogging pressure of the waste filling the waste storage body 87, the waste storage body 87 can be efficiently filled with waste.

  In addition, the waste storage body 87 is formed of a stretchable bag (for example, a non-breathable bag or a breathable bag whose volume increases as the internal pressure increases, such as a rubber balloon or a stocking).

That is, when the empty waste storage body 87 is loaded on the waste support base 223, the waste storage body 87 is supported on the upper surface of the waste support base 223 in a state where the waste storage body 87 is reduced to the minimum volume. By filling the waste storage body 87 with the waste from the waste duct 93, the internal pressure of the waste storage body 87 becomes high and expands. The volume of the waste container 87 is increased in proportion to the amount of waste filled.

  Therefore, the waste container 87 is loosely compressed and filled into the waste container 87 by the contraction pressure (the elastic pressure of the waste container 87) that reduces the waste container 87. By increasing the clogging pressure of the waste filling the waste storage body 87, the waste storage body 87 can be efficiently filled with waste. In addition, when the waste container 87 is filled with a predetermined amount of waste, and the waste container 87 is completely filled with waste, the waste container 87 expanded to a predetermined size is supported. By removing from the table 223, the waste is filled and held in the waste storage body 87 by the self-contraction pressure of the waste storage body 87. That is, it is possible to save the trouble of closing the opening of the waste container 87 when the waste container 87 is taken out from the waste support base 223. The waste container 87 can be easily removed from the waste support table 223.

  In addition, it is desirable that the waste container 87 is formed using waste (rice straw) or wood or grass fiber having the same characteristics as the raw material. When the waste container 87 is formed of a material having the same properties as the waste to be filled, waste and waste as a soft cellulose raw material for cellulosic bioethanol production in a state where the waste container 87 is filled with waste. Both storage bodies 87 can be supplied. At the time of bioethanol production, the trouble of taking out waste from the waste storage body 87 can be saved. It is possible to improve the handling workability of the waste and the waste container 87 as the soft cellulose raw material.
