Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, in particular to a side-mounted carrot harvester. Background Art

[0002] As a widely planted root vegetable, the harvesting process of carrots traditionally relies on manual labor or simple machinery, which has problems such as high labor intensity, low efficiency, and high cost. Especially in large-scale planting areas, traditional harvesting methods can no longer meet the needs of modern agriculture for high efficiency, precision, and low loss. Most of the existing carrot harvesting machines have complex structures and cumbersome operations, and have poor adaptability to carrots in different growth conditions, which can easily cause damage to carrots or excessive soil residue, affecting the quality of carrots and subsequent processing. In particular, the parts used for arranging the seedlings at the front end of the existing carrot harvester are usually made of two iron rod-shaped parts bent inward. Although the carrot seedlings can be gathered to the middle during harvesting, they have large resistance and are easy to tear the carrot seedlings apart, resulting in the carrots being unable to be clamped and transported by the conveyor belt, resulting in carrots being left behind and the harvest rate being low.

[0003] In addition, during the carrot harvesting process, the removal of vine leaves and the cleaning of soil are important links, which directly affect the cleanliness and final quality of carrots. The position of the vine cutting device on the traditional carrot harvester is fixed. During harvesting, the carrot vines of some shorter carrots are not completely removed and still need to be manually removed again, which is inefficient. In addition, the large number of carrots increases the difficulty and cost of subsequent processing. Summary of the invention

[0026] The working principle of the present invention is as follows: the bracket 1 is fixed to the side of the tractor or crawler agricultural machine through the fixing hole 13 on the mounting plate 2, and the first hydraulic motor 43, the second hydraulic motor 64, the third hydraulic motor 83, the fourth hydraulic motor 94 and the hydraulic cylinder 12 are connected to the hydraulic system on the tractor or crawler agricultural machine. When harvesting, the hydraulic cylinder 12 is controlled to extend so that the hydraulic cylinder 12 drives the conveying mechanism 4 to rotate downward, so that the two sorting rods 61 are located on both sides of the whole ridge of carrots, and the loosening shovel 5 is inserted into the soil, and the second hydraulic motor 64 drives the conveying mechanism 4 to rotate downward. The movable sorting rod 61 rotates, so that the spiral line 62 on the sorting rod 61 will lift up the fallen carrot seedlings, and as the agricultural machine moves, the inclined sorting rod 61 will push all the carrot seedlings to a vertical state. When the agricultural machine moves, the loosening shovel 5 will shovel the soil at the bottom of the carrots, and at the same time, the vertical seedlings will enter between the two belts 42 from the eight-shaped openings of the two conveying mechanisms 4, and one of the guide wheels 44 will rotate through the first hydraulic motor 43, so that the guide wheel 44 drives the belt 42 to rotate, so that the two belts that are in contact and rotate at the same time 42 tightens and transports the carrot leaves obliquely upward, so that the carrots are pulled out of the loosened soil and transported backward. During the transportation process, the third hydraulic motor 83 drives the rotating rod 82 to rotate, so that the rotating rod 82 drives the soil-beating bar 81 to rotate, so that the soil-beating bar 81 hits the carrots during the transportation process, so that the soil attached to the surface of the carrots is shaken off. When the carrots are transported to the adjustable seedling cutting mechanism 9, the two fourth hydraulic motors 94 can simultaneously drive the two seedling cutting blades 93 to rotate, so that the two seedling cutting blades 83 cut the carrot leaves. The cut carrots will fall into the blanking plate 11 and slide to one side along the inclined surface of the blanking plate 11. The cut seedlings will be thrown back into the field along with the conveying of the conveying mechanism 4. When the harvested carrots are exposed to a lower height above the ground, the driving member 95 can be twisted to rotate, so that the driving member 95 drives the screw 92 to rotate, and the screw 92 drives the adjustment plate 91 to move, so that the adjustment plate 91 moves along the direction of the guide rod 97 in the direction away from the moving mechanism 4, so that the seedling cutting blade 93 on the adjustment plate 91 can be closer to the carrots, so that the carrot seedlings can be removed more thoroughly.
