This invention relates to a charging device for a grain tank.

0002

[Conventional technology]

Conventionally, a threshing device and a grain tank were installed on the machine, and the grain lifting cylinder of the threshing device was used as a grain tank. A combine harvester that is inserted into a tank to lift and feed grain into a grain tank. A casing with a throwing port is attached to the top of the grain barrel, and the grains are transported by Grain is thrown into the tank using a throwing blade protruding from the top end of the spiral shaft. is already known.

0003

[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. , the grain can be poured into the narrow space on the side closer to the side wall, but the grain can be poured into the narrow space on the side far away. Even if the grain tank is made larger due to insufficient input capacity for the large space available, could not be fully utilized.

[Means to solve the problem]

This invention is equipped with a threshing device and a grain tank on the machine base, and the grain lifting cylinder of the threshing device is A combine harvester that is inserted into a grain tank and lifts and inputs grain into the grain tank. A rotary disk for throwing the lifted grains is provided on the upper part of the grain lifting cylinder, and the rotary disk A grain tank is constructed by installing a throwing restriction plate on a part of the outside of the tank to catch thrown grains Input less grain on the narrow side of the storage space and more on the wider side. The above-mentioned problem was solved.

[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 grains are thrown evenly over the entire rotation, but the throwing restriction plate does not catch the thrown grains. At the same time, the throwing blades are used to move part of the ball to the area where there is no throwing restriction plate, and the throwing direction is , the amount of input to the side with the throwing restriction plate is reduced, and the throwing control is reduced. The amount of input to the side without the limit plate increases.

【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] Inside the cabin 4, there is a driver's seat 20, an operation panel 21, a lever panel 22, and The bottom plate 5a of the extending portion of the tank 5 is along the top of the threshing device 3, and is located on the opposite side from the threshing device 3. The engine 23 and radiator are installed on the machine base 2 at the bottom of the grain tank 5 in order from the front. 24, and a support frame 25 and a fuel tank 26 are provided at the rear.

[0009] Further, 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 30. ... is fixed to the upper part of the helical shaft 13a, and is brought close to directly below the bearing 27 of the helical shaft 13a. Four arms 31, whose outer parts are bent downward, are welded to the plate 29 attached. , a scooping part 32 is provided on the outer circumferential side of the arms 31... with the lower part facing toward the rotation direction. A bent throwing blade 32 is fixed at the lower end of the throwing blade 32. The circular opening of the section fixes a dish-shaped rotary disk 33 which is loosely fitted to the outer periphery of the upper end of the grain-lifting cylinder 13. Four diffusion vanes 35 are radially fixed to the lower surface of the rotary disk 33.

0010 Furthermore, 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 towards the rear of tank 5, the rear loading space is narrow and the front loading space is narrow. The space is large. Support arms 3 on the outside and rear of the grain lifting cylinder 13 are provided. 0,30, a belt-shaped throwing restriction plate 36 is placed narrowly around the outer periphery of the rotation locus of the throwing blade 32. The top plate of the grain tank 5 is installed in an arcuate manner along a gap. 5a is provided with an overflow port to which an overflow valve 34 is hinged.

[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 falls from the opposing gap, but other items are carried around or thrown from the throwing blade 32. The throwing direction is changed to the rotating direction, and more balls are thrown toward the front side where there is no throwing restriction plate 36. In addition, since the rear part is close to the rear wall of the grain tank 5, the above-mentioned throwing restriction plate 36 is installed. Of course, even if you install one, the back will accumulate faster than the front, and during that time , the lower pressure-sensitive sensor 37 detects 1/3 of the input amount, and the middle pressure-sensitive sensor 38 detects 2/3 of the input amount, and the upper pressure sensor 39 detects that it is almost full. However, when the accumulated grains approach the lower surface of the rotary disk 33, the diffusion blades 35 ・Since the grains accumulated at the rear are scraped out and thrown forward, the lifting of the grain tank 5 is reduced. Almost enough grain can be thrown into a portion far away from the grain barrel 13.

[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.

[0014]

[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. A turntable 33 is provided, and a part of the outside of the turntable 33 is provided with a throwing plate that catches thrown grains. Since the lifting restriction plates 36 are provided oppositely, the grains lifted by the grain lifting tube 13 are completely transferred by the rotary plate. Throwing can be done all around the circumference, and in this case, the throwing restriction plate 36 is limited to the throwing space. The input is restricted by receiving grains thrown to the narrow side of the The thrown grains are taken to a larger space where there is no throwing restriction plate 36, or their direction is changed. It becomes possible to input the grains by changing the grains, and the grain lifting cylinder 13 is placed in the grain tank 5. The grain tank is installed in an uneven position, or the grain tank is irregularly shaped in the front, back, left, right, and top and bottom. Even if it is in a shape, the space for each part can be used effectively.
