Technical Field

[0001] The invention relates to the technical field of wheat harvesting, in particular to a lodging wheat harvesting and recovery device. Background Art

[0002] Wheat is one of the main crops planted in northern my country. Wheat harvesting becomes a very important link during the wheat harvest season. Given that arable land in the north is relatively concentrated and is generally planted by families, existing large-scale harvesters can achieve automated harvesting. During the wheat planting and growth process, due to weather problems, large areas of wheat may occasionally fall over, and usually the fallen wheat needs to be harvested manually.

[0003] There is a lodged wheat harvesting device, which includes a straw divider, a straw wheel and a cutting knife. When a harvester harvests the lodged wheat, the straw wheel needs to be lowered, and the lodged wheat is lifted up by a lever on the rotating straw wheel, and the harvesting table at the front end of the harvester cuts off the lifted wheat, thereby completing the harvesting.

DETAILED DESCRIPTION

[0031] The present invention is further described in detail below through the accompanying drawings and embodiments.

[0032] like Figure 1-6 Shown is a fallen wheat harvesting and recovery device, comprising a base 1, a plurality of wheat supporting mechanisms 2 and a transmission mechanism 4.

[0033] The wheat supporting mechanism 2 includes a cone barrel 21, a serrated ring 23 and a wheat supporting shaft 24. The wheat supporting shaft 24 is rotatably connected to one side of the base 1 and can rotate freely. The cone barrel 21 is fixedly mounted on one end of the wheat supporting shaft 24 and is in the shape of a cone structure, which can be easily inserted into the fallen wheat. There are multiple serrated rings 23 that are equidistantly sleeved on the cone barrel 21, and the serrated rings 23 are used to support the fallen wheat. The serrated rings 23 are designed as a slope near the outer end for conveying wheat in layers.

[0034] The transmission mechanism 4 is located in the base 1 and is responsible for driving the reel-supporting shaft 24 and the reel wheel 3. It includes a shaft and a plurality of bevel gears 43. The shaft is rotatably connected in the base 1 and can rotate freely. The shaft is divided into multiple sections, and a bevel gear 43 is fixedly installed on each section. A bevel gear 43 is also installed at the other end of the reel-supporting shaft 24, and is perpendicular to and meshed with the bevel gear 43 on the shaft. In this way, when the shaft rotates, the reel-supporting shaft 24 will also rotate.

[0035] In order to improve the transmission efficiency, the rotating shaft includes a first rotating shaft 41 and a second rotating shaft 42. The first rotating shaft 41 and the second rotating shaft 42 are arranged vertically, and spur gears 44 are fixedly mounted on the first rotating shaft 41 and the second rotating shaft 42 respectively, and the two spur gears 44 are meshed. In this way, when one rotating shaft rotates, the other rotating shaft will also rotate.

[0036] A plurality of air jet holes 25 are provided on the cone barrel 21, and an air pipe 8 is installed in the base 1. The air pipe 8 is connected to the air jet holes 25 through the supporting wheat rotating shaft 24. When the supporting wheat rotating shaft 24 rotates, the air jet holes 25 will spray air to blow away the insects and dust on the fallen wheat.

[0037] A shell 71 is fixedly installed in the base 1, and one end of the second rotating shaft 42 is rotatably connected to the shell 71. An active impeller and a driven impeller are installed in the shell 71, and the shell 71 is filled with a fluid medium. An output shaft 72 is installed at one end of the driven impeller and extends outside the shell. A rope 73 is wound around one end of the output shaft 72, and a partition 82 is connected to one end of the rope 73. A notch of the partition 82 is opened on the air pipe 8, and the partition 82 slides vertically in the notch of the partition 82. A spring 83 is installed between the bottom of the partition 82 and the air pipe 8. When the output shaft 72 rotates, the rope 73 will be pulled to move the partition 82 up and down, thereby changing the ventilation volume of the air pipe 8. At the same time, when the supporting shaft 24 rotates, the partition 82 is pulled up to open the air pipe 8, so that the gas in the air pipe 8 can flow through the jet hole 25 to discharge the jet. Since the housing 71 is filled with a fluid medium, when the rope 73 is tightened, the output shaft 72 stops rotating. When the device stops, the partition 82 rebounds into the air pipe 8 under the action of the spring 83 to close the air pipe 8.

[0038] A feeding box 5 is fixedly mounted on the top of the base 1. A connecting arm 32 is mounted on the feeding box 5, and one end of the connecting arm 32 is rotatably connected to a reel shaft 31. A reel wheel 3 is fixedly mounted on the reel shaft 31.

[0039] The transmission mechanism 4 further comprises a belt 45, one end of which is sleeved on the reel shaft 31, and the other end of which is sleeved on the first shaft 41. Thus, when the first shaft 41 rotates, the reel 3 also rotates.

[0040] In addition, the device also includes a straightening mechanism 6, which is fixedly mounted on the base 1 and located between the reel-supporting mechanism 2 and the reel 3. The straightening mechanism 6 includes a fixed arm 61, a plurality of straightening plates 62, a plurality of baffles 63 and a top plate 64. There are multiple fixed arms 61 and they are fixedly mounted on the base 1. A plurality of straightening plates 62 are respectively fixedly mounted on one end of the fixed arm 61, and a sawtooth groove 621 is provided on the straightening plate 62. The sawtooth groove 621 is sloped away from the fixed arm 61 and is perpendicular to the straightening plate 62 on one side close to the fixed arm 61. The top plate 64 is fixedly mounted on the top of the plurality of straightening plates 62, and a plurality of baffles 63 are fixedly mounted on the bottom of the top plate 64. A baffle 63 is provided between every two straightening plates 62. An arc groove 622 for rolling the reel 3 is provided on the top of the straightening plate 62 close to the fixed arm 61.

[0041] The above-mentioned embodiments are for inspiration. Through the above-mentioned description, relevant staff can make various changes and modifications without departing from the scope of the invention. The technical scope of this new type of use is not limited to the content in the specification, and its protection scope must be determined according to the scope of the claims.
