[Problem that the idea aims to solve]

The grain tank charging device in the known combine harvester is capable of transporting grain only through the throwing port. Since only rice grains can be thrown, the grain barrel is removed from the bottom of the grain tank. When inserted into the tank, it was not possible to fill the entire grain tank. Therefore, the upper part of the grain-lifting cylinder was made open at the front, and the fried grains were transported from the top side. A rotary disk with a throwing blade was used to receive and throw the ball. However, grain The insertion position of the grain lifting cylinder relative to the tank was deviated from front to back or left and right in plan view. , grains are deposited early on the side closer to the side wall, and input to the far side is delayed, resulting in uneven deposition height. Became.

[0005]

[Effect]

The grains that have been harvested, threshed, and sorted are transported by a lifting cylinder, and the upper end of the transporting cylinder is The grains spilled onto the rotating disk due to the centrifugal force of the rotating disk itself and the rotation of the throwing blades. The grain is thrown evenly around the entire rotation and filled into the grain tank. As a result, deposited The top surface of the grain is higher on the side that is closer to the side wall of the grain tank and lower on the side that is farther away. , the dispersion blades are deposited on the side where the deposition surface approaches the rotary disk as the charging progresses. Scrape up the grains and throw them to the lower side of the pile surface, for example, the side that is farther from the side wall. to ensure that the pile heights in each part of the grain tank are approximately equal.

【Example】

An embodiment of the present invention will be described with reference to the combine harvester shown in the drawings. A threshing device 3 is mounted on one side of the machine stand 2, and a grain tank 5 is arranged on the other side. In front of the threshing device 3, a reaping device 6 and the harvested grain culm are held and conveyed while adjusting the handling depth. The pre-processing device consisting of the grain conveying device 7 which knots and supplies the grain to the threshing device 3 can be tilted up and down. The grain tank 5 is mounted on a frame 8 with an outer lower transfer spiral 10. It is supported so that it can rotate outward about the axis of the The transfer spiral 10 has a standing portion 11a and a raised portion 11a at the end thereof. A grain lifting/discharging tube 11 consisting of an undulating portion 11b is arranged in series, and is placed above the grain tank 5. The surface is provided with a groove 12 which is oblique in plan view and into which the undulating portion 11b fits. Both sides are raised upwards to expand the storage capacity.

[0007] The grain lifting cylinder 13 of the threshing device 3 is inserted from the bottom plate of the grain tank 5 near the threshing device 3. The grains in the grain tank 5 are divided into parts corresponding to the bottom plate. The hydraulic cylinder 15 that tilts the grain tank 5 to discharge the grains is a single-acting type. Then, the lower part is pivoted on the machine base 2, and the upper end of the piston is moved from the underframe 16 of the grain tank 5. It is rotatably connected to the hanging bracket 16a, and the grain tank 5 is pushed up to the outside. When the grain tank 5 tilts to Since the load for reducing the hydraulic cylinder 15 is significantly reduced when the hydraulic cylinder 15 is located at , a wire with a spring 17 interposed between the cylinder and the bracket 16a 18, and when the grain tank 5 is pushed up, the spring is connected via the wire 18. 17 is in a stretched state, so that when the grain tank 5 returns and rotates, The hydraulic cylinder 15 operates smoothly for contraction.

[0008] 20 is the driver's seat, 21 is the operation panel, 22 is the lever panel, and 5a is the removal of the grain tank 5. It is a bottom plate that runs along the top of the grain device 3, and is a lower machine base of the grain tank 5 on the opposite side from the threshing device 3. 2, an engine 23 and a radiator 24 are installed in order from the front, and a support frame is installed at the rear. 25 and a fuel tank 26 are provided.

[0009] Then, it is attached to the upper end of the helical shaft 13a of the grain lifting cylinder 13 via a bearing 27. The lower part of the mounting plate 28 is screwed onto the outer periphery of the grain lifting cylinder 13 and has three inverted L-shaped support arms 3. It is fixed to the upper part of Four arms 31, whose outer parts are bent downward, are welded to the plate 29, which is attached to the plate 29. However, on the outer peripheral side of those arms 31, a scooping part 3 is provided with the lower part facing toward the rotation direction side. A bent throwing blade 32 is fixed as 2a, and the lower end of the throwing blade 32... The circular opening at the bottom fixes a dish-shaped rotary disk 33 that is loosely fitted around the upper end of the grain-lifting cylinder 13. Four diffusion vanes 35 are fixed radially on the lower surface of the rotary disk 33. The top plate 5b of the grain tank 5 has an overflow port having an overflow valve 34. is provided.

0010 In addition, the capacity of the part of the grain tank 5 that extends to the side of the thresher 3 and is mounted on it is as follows: It is smaller than the hanging part on the side of the transfer spiral 10, and the grain lifting cylinder 13 has a grain holder in a plan view. Since it is located toward the rear of the link 5, the belt is attached to the outer and rear support arms 30, 30. A shaped throwing restriction plate 36 is curved and attached along the outer circumferential rotation locus of the throwing blade 32. It is written.

[0011] In the combine harvester described above, the grain culm harvested by the reaping device 6 is transferred to the grain culm conveying device. The grain is conveyed to the rear while the handling depth is adjusted by the holder 7, and then transferred to the self-threshing type threshing device 3 in the usual manner. Therefore, the threshing device 3 performs threshing and sorting, and the sorted grains are The grains are lifted by the lifting cylinder 13, and rotated together with the spiral shaft 13a at the upper end thereof. It overflows onto the rotary disk 33, and due to the centrifugal force caused by the rotation of the rotary disk 33 and the throwing blades 32... Due to the throwing force of Ru.

0012 At that time, since the lower part of the throwing blade 32 is bent diagonally toward the rotation direction, The grains on the rotary disk 33 are scooped up and thrown efficiently, and the grains around the lifting cylinder 13 are smelled. At the rear, the throwing restriction plate 36 catches the thrown grains, so some of the grains will fall, but the others will be carried around or thrown in the direction of rotation of the throwing blade 32. The throwing direction is changed and more balls are thrown toward the front where there is no throwing restriction plate 36. Also, the rear Since it is close to the rear wall of the grain tank 5, if the throwing restriction plate 36 is not provided, Of course, even if it is installed, the rear part will accumulate faster than the front part, and during that time, the downward pressure sensing The sensor 37 detects the input amount 1/3, and the intermediate pressure sensor 38 detects the input amount 2/3. 3, and the upper pressure sensor 39 detects that it is almost full, but the When the piled grains approach the lower surface of the rotary disk 33, the diffusion blades 35... Since the accumulated grains are scraped out and thrown forward, they are removed from the grain lifting cylinder 13 of the grain tank 5. It is possible to pour almost enough water into areas that are far apart, and there is also an overflow port. It is possible to improve the efficiency of storing grains by slowing down the overflow of grains.

[0013] When the grain tank 5 is almost full, the upper pressure-sensitive sensor 39 detects the grains and the grain is removed. If the operator, etc. issues an alarm, pull the aircraft to a truck parked on the road and remove the grain. The undulating part 11b of the grain lifting discharge pipe 11 is made to stand up diagonally, and its discharge port is connected to the loading platform of the transport vehicle. The inside of the transfer spiral 10 and the grain lifting discharge tube 11 is rotated horizontally so as to face upward. When the auger is driven, the grains above the transfer spiral 10 are lifted and discharged, while , some of the grains in the upper part of the threshing device 3 flow down, and then a hydraulic cylinder When the barrel 15 is extended, the grain tank 5 rotates outward, and the grain tank 5 rotates outward. All grains flow down and are pumped and discharged.

[Effect of the idea]

The present invention has a threshing device 3 and a grain tank 5 on the machine stand 2, and the threshing device 3 is The grain cylinder 13 is inserted into the grain tank 5 and the grains are lifted and put into the grain tank 5. In the combine harvester, the grains lifted to the top of the grain lifting cylinder 13 are thrown. Since a turntable 33 is provided and diffusion blades 35 are protruded from the lower surface of the turntable 33, the grain tank is Even if there is a difference in the storage space of the container 5 around the grain frying tube 13, the storage space is small. When the grain accumulation surface rises quickly on the side, the diffusion blade 35 scrapes out the grains in that area. As a result, the grains are thrown to the side with a lower deposition surface. can be added almost equally.
