Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and more specifically, to a harvester. Background Technology

[0002] A harvester is a specialized feed processing machine designed to handle various crop stalks, especially corn stalks, wheat straw, and rice straw. Through a series of complex mechanical operations, including cutting and crushing, this machinery can transform these crop stalks into high-quality feed suitable for livestock farming.

[0003] However, the hay harvested by combine harvesters must be transported to specific locations for mixing and processing. This process involves transferring the hay from the harvester's storage bins to a mixer for further processing before it can be used to feed animals. This process is not only labor-intensive and resource-intensive but also relatively inefficient. To accomplish this task, workers must shuttle between the fields and processing sites, unloading the hay from the harvester's storage bins and loading it into transport vehicles. After the transport vehicles deliver the hay to the designated mixing location, workers must unload it from the vehicles and transfer it to the mixer. This process requires a significant amount of manpower, time, and fuel, increasing overall operating costs. Summary of the Invention

[0004] To address the technical problem that harvesters cannot directly mix materials, this solution provides a harvester that can directly input the harvested forage into the mixing tank for mixing, achieving simultaneous harvesting and mixing, saving time and labor and increasing efficiency.

[0026] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments.

[0027] like Figure 1 As shown, a harvester includes a mobile vehicle body 100, a harvesting assembly 200, a drive system 300, a mixing chamber 400, and a feeding device 500. The mobile vehicle body 100 serves as the mobile carrier, on which the harvesting assembly 200, the mixing chamber 400, and the feeding device 500 are mounted. The harvesting assembly 200 shreds the forage, and the forage is then conveyed to the mixing chamber 400 by the feeding device 500. After being mixed in the mixing chamber 400, the forage is discharged from the mixing hopper and fed to farmed animals such as chickens, ducks, and geese. The above features are described in detail below.

[0028] The mobile vehicle 100 is generally a four-wheeled or tracked vehicle, driven by a diesel engine. The mobile vehicle 100 has wheels 110 at its bottom. The harvesting assembly 200 consists of the harvester's collecting and cutting components, including harvesting rollers, a cutter, and forage conveying pipes. The harvesting assembly 200 is existing harvester technology, and its specific structure will not be described in detail. After the harvester harvests and chops the forage, the resulting forage fragments are fed into the mixing tank 400.

[0029] like Figure 2 As shown, the mixing tank 400 is fixed to the front of the vehicle. The mixing tank 400 includes a tank body 410 and a mixing part 420, which is connected inside the tank body 410.

[0030] The container 410 has a semi-cylindrical bottom 411 and a square body 412, which are fixedly connected. A second opening 413 is provided at the top of the body 412. The container 410 also includes a fixing frame 430 on the outer periphery of the bottom 411 and the body 412. The bottom of the fixing frame 430 is fixed to the truck bed. The fixing frame 430 includes an upper frame 431 and a lower frame 432, which are fixedly connected vertically. The upper frame 431 is a rectangular frame, and the lower frame 432 is a trapezoidal frame. The trapezoidal structure of the lower frame 432 increases its volume, making its connection to the mixing tank 400 more stable. A reinforcing column is fixed along the length of the upper frame 431 to prevent deformation under stress.

[0031] A third opening 440 is provided on the housing 410, which connects to the interior of the mixing tank 400. A guide plate 441 is fixedly connected to the outer periphery of the third opening 440. The guide plate 441 is U-shaped and arranged along the circumference of the third opening 440. A door panel 442 is slidably connected to the guide plate 441, and the door panel 442 is used to open and close the third opening 440.

[0032] like Figure 2 As shown, the mixing unit 420 includes a third rotating shaft 421, a support column 422 fixed on the third rotating shaft 421, and a mixing spoon 423. The third rotating shaft 421 is rotatably connected to the connection between the body 412 and the bottom 411 of the mixing box 400 along its length. The mixing spoon 423 is fixed to the side of the end of the support column 422. The mixing spoon 423 is preferably a flat plate, and the connection between the mixing spoon 423 and the support column 422 is reinforced with reinforcing ribs. When the third rotating shaft 421 rotates, it can drive the support column 422 and the mixing spoon 423 to rotate inside the mixing box 400, and the mixing spoon 423 can mix the forage in the mixing box 400 evenly. The mixing unit 420 has multiple support columns 422, and the included angle between two adjacent support columns 422 is 60~90°. Within this included angle range, the mixing unit 420 can fully mix the forage, making it more evenly mixed. A support column 422 and a corresponding stirring spoon 423 are fixed on the third rotating shaft 421 in the mixing tank 400, directly opposite the third opening 440. This support column 422 and the corresponding stirring spoon 423 can not only be used to mix the forage, but also push the forage towards the third opening 440, transferring the forage from the third opening 440 to outside the mixing tank 400.

[0033] The drive system 300 includes a driver and a transmission system. There are a first transmission system, a second transmission system, and a third transmission system. The first transmission system transmits power from the driver to the wheels 110 of the moving vehicle 100, causing the moving vehicle 100 to move. The second transmission system transmits power from the driver to the harvesting assembly 200, causing the harvesting assembly 200 to shred the forage. The third transmission system transmits power from the driver to the mixing chamber 400, causing the third rotating shaft 421 inside the mixing chamber 400 to rotate, thus mixing the forage.

[0034] The drive system 300 consists of a driver and three transmission systems, which are used to drive the wheels 110, the harvesting assembly 200, and the mixing tank 400, respectively. With the driver and the three transmission systems, the wheels 110, the harvesting assembly 200, and the mixing tank 400 can be driven simultaneously by a single driver, avoiding the need for multiple drivers and saving fuel and space.

[0035] like Figure 3 As shown, the feeding device 500 includes a feeding rack 510, which is attached to the mixing tank 400, specifically to a fixed frame 430 at the edge of the third opening 440. A lifting device 520 is fixed to the feeding rack 510, and a load-bearing plate 530 is fixed to the lifting device 520.
