Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery, and in particular to a grain recycling bin and a harvester. Background Technology
[0002] During the process of removing the husks from corn ears, hullers easily shed a large number of corn kernels. Corn harvesters collect these kernels during operation, typically storing them in a kernel collection bin. Commercially available kernel collection bins usually have the outlet located at the bottom of the bin, with a fixed opening size. Because the kernels fall quickly, this design makes it easy for kernels to spill when the outlet is suddenly opened, leading to difficulties in unloading and transporting them. Furthermore, due to the harsh harvesting environment, impurities accumulate in the kernel collection bin, making cleaning difficult. Therefore, it is necessary to provide a harvester that overcomes these shortcomings. Utility Model Content

[0039] See Figures 1 to 6The embodiment provides a grain recycling bin 4 for storing grains dropped during harvesting. The grain recycling bin 4 includes a bin body 40, a baffle 43 mounted on the bin body 40, and an adjusting assembly 44 for adjusting the baffle 43. A feed inlet 401 is provided at the top of the bin body 40, through which the recycled grains are stored in the grain recycling bin 4. A bottom plate 41 is provided at the bottom of the bin body 40 to enclose it. A discharge outlet 402 is provided at the lower part of a first side wall 42 on one side of the bin body 40. The baffle 43 is movably mounted on the first side wall 42 and can be adjusted by the adjusting assembly 44 to block the discharge outlet 402. The adjusting assembly 44 is fixed to the bin body 40 and also connected to the bottom of the baffle 43. The adjusting assembly 44 can adjust the position of the baffle 43 on the first side wall to block the discharge outlet 402, thus achieving the purpose of either blocking or opening the discharge outlet 402 for material discharge. The adjusting assembly 44 includes a rotating shaft 441 that is rotatably mounted horizontally above the discharge port 402. Both ends of the rotating shaft 441 are connected to the housing 40. One end of an adjusting arm 442 is fixed to the rotating shaft 441, and one end of a movable arm 443 is fixed to the lower end of a baffle 43. The other end of the movable arm 443 is movably connected to the adjusting arm 442. An adjusting handle 444 is fixed to the rotating shaft 441, driving the rotating shaft 441 to rotate. Specifically, turning the adjusting handle 444 causes the rotating shaft 441, which is integrally mounted with the adjusting handle 444, to rotate. This, in turn, causes the adjusting arm 442 to rise, and the movable arm 443 connected to the adjusting arm 442 to rotate accordingly. This, in turn, causes the baffle 43, which is fixed to the movable arm 443, to rise, opening the discharge port 402. The area of the discharge port 402 covered by the baffle 43 can be adjusted by controlling the rotation range of the adjusting handle 444. When the adjustment range of the adjusting handle 444 is small, the area covered by the baffle 43 is large; conversely, when the adjustment range of the adjusting handle 444 is large, the area covered by the baffle 43 is small. This method of adjusting the size of the discharge port 402 is simple, easy to operate, and saves time and effort.
[0040] In a preferred embodiment, the first sidewall 42 includes an upper sidewall 421 and a lower sidewall 422. An intermediate plate 423 is also provided between the upper sidewall 421 and the lower sidewall 422. The discharge port 402 is located on the lower sidewall 422, which converges inward toward the box body 40. The upper sidewall 421 and the lower sidewall 422 are connected by a connecting plate 424, which is horizontally arranged. Below the discharge port 402, a grain discharge plate 45 is also provided. The bottom of the grain discharge plate 45 is connected to the bottom plate 41. The grain discharge plate 45 is folded downward around the edge connected to the bottom plate 41 to form a discharge channel 403, which facilitates the transport of grains. The grains can be transported and transferred through the discharge port 402 and the discharge channel 403, which can save manpower and material costs. When the grain discharge plate 45 is folded up, the grain discharge plate 45 and the upper sidewall 421 are located on the same plane in the vertical direction. On both sides of the discharge port 402 on the lower side wall 422, mounting seats 425 are respectively provided for mounting the rotating shaft 441. The mounting seats 425 are symmetrically arranged, and the rotating shaft 441 rotates accordingly within the mounting seats 425. At the same time, a fixed seat 431 is also provided between the baffle 43 and the movable arm 443. The fixed seat 431 is fixed to the lower side of the baffle 43, and one end of the movable arm 443 is movably connected to the fixed seat 431. The movable arm 443 and the fixed seat 431 are movably connected to each other to avoid the movable arm 443 breaking from the baffle 43 during the rotation of the rotating shaft 441 by the adjusting handle 444, which would affect the baffle 43's blocking and opening of the discharge port 402. To facilitate smoother obstruction or opening of the discharge port 402 by the baffle 43, a limiting plate 426 is provided on the lower side wall 422 along the circumference of the discharge port 402. A pad 427 is vertically positioned between the limiting plate 426 and the discharge port 402, with the pad 427 located between the lower side wall 422 and the limiting plate 426. This creates a slot 428 above the discharge port 402, allowing the baffle 43 to be movably positioned within the slot 428, thus limiting its movement on the lower side wall 422. The baffle 43 is provided with a limiting part 432, which abuts against the slot 428, enhancing the stability of the baffle 43's movement. Protective walls 451 are also provided on both sides of the grain discharge plate 45, fitting snugly against the housing 40 and connected to the housing 40 via pins. To prevent grains from falling during unloading, a protective wall 451 is also provided at the bottom of the discharge plate 45. To ensure smooth downward folding of the discharge plate 45, a pin connecting it to the housing 40 is located on the upper side of the bottom plate 41, and part of the discharge plate 45 extends downward toward the bottom plate 41. The upper side plate and the discharge plate 45 are connected and fixed by a buckle 452 to prevent the discharge plate 45 from slipping and causing damage during operation.
[0041] In a preferred embodiment, to facilitate the dropping of grains within the container 40, the intermediate plate 423 is inclined, and the bottom plate 41 is also inclined. The height of the first side of the container 40 is higher than the opposite side of the first side on the container 40, thus causing the grains to fall towards the side where the discharge port 402 is located. This arrangement prevents grains from accumulating inside the container 40, improving the recycling efficiency. Furthermore, to facilitate observation of the number of grains inside the container 40 and timely loading and unloading of grains, an observation port 404 is provided to prevent grains from overflowing from the container 40.
[0042] like Figure 7 The harvester shown includes a header 1, a conveyor 2, a peeler 3, and a grain collection box 4 provided in any of the embodiments. With the harvester's operating direction as the front, the grain collection box 4 is located on the left side of the harvester, with its first side facing outside the harvester. During the harvester's operation, after the header 1 cuts the straw, the ears of grain are conveyed by the conveyor 2 to the peeler 3 to remove the husks. During this process, a large amount of grain falls, which is collected by the grain collection box. The grain collection box 4 provided in this embodiment has a simple structure and is easy to operate, saving manpower and resources during grain collection and unloading, and improving harvesting and unloading efficiency.
[0043] It will be apparent to those skilled in the art that various modifications and variations can be made to the exemplary embodiments of the present invention without departing from the spirit and scope of the present invention. Therefore, it is intended that the present invention cover modifications and variations falling within the scope of the appended claims and their equivalents.
