[0002] Agriculture is an industry that utilizes the growth and development laws of animals and plants to obtain products through artificial cultivation. Agriculture belongs to the primary industry, and the science that studies agriculture is agronomy. The objects of agricultural labor are living animals and plants, and the products obtained are the animals and plants themselves. Agriculture is a basic industry that provides support for the construction and development of the national economy. Corn is the main food crop in my country. In recent years, corn harvesters have been frequently used to harvest and peel corn.

[0003] However, when peeling drier or over-mature corn, the fallen corn kernels will be collected by the corn kernel recovery device, but the existing recovery device can only filter out debris, such as some roots, stems, and leaves mixed in it, and cannot process these retained debris, resulting in affecting the effect of subsequent filtering of corn kernels. In addition, similar models of corn harvesters and corn kernel recovery devices have the problem of no automatic unloading and difficulty in unloading when the kernels are wet. Utility Model Content

[0024] Embodiment 2, as Figure 1-Figure 5 As shown, the difference between this embodiment and embodiment 1 is that a discharge port 10 is provided at the bottom of the collecting bucket 2, and a through port 11 is provided on one surface of the collecting bucket 2; the crushing mechanism 9 includes two crushing rollers 901 rotatably connected to the crushing box 6 through bearings, a crushing motor 902 is fixed to one surface of the crushing box 6, a worm 903 is fixed to the output end of the crushing motor 902, and the other end of the worm 903 is rotatably connected to a support plate through a bearing, and the support plate is fixed to the crushing box 6, one end of the two crushing rollers 901 penetrates one surface of the crushing box 6 and is sleeved and fixed with a worm gear 904, the two worm gears 904 are symmetrically arranged on both sides of the worm gear 903, and the two worm gears 904 are meshed with the worm gear 903; two guide plates 905 are respectively fixed in the crushing box 6, and the bottom of the crushing box 6 is open; the position where the four-way pipe 8 is installed and connected is located at the bottom end of the crushing box 6; an air outlet is provided on one surface of the fan box 7.

[0025] The effect achieved by the entire embodiment 2 is that the discharge port 10 is to allow the retained matter on the filter plate 3 to smoothly enter the crushing box 6, and the through port 11 allows the corn kernels after filtering to smoothly enter the storage bucket 4; the crushing motor 902 drives the worm 903 to rotate, and the worm 903 can drive the two worm wheels 904 to rotate inward together, and the two worm wheels 904 can drive the two crushing rollers 901 to rotate inward together. Under the mutual cooperation of the two crushing rollers 901, the retained branches and leaves can be crushed, and the crushed debris is directly discharged from the crushing box 6; the guide plate 905 can make the sundries fall smoothly between the two crushing rollers 901 for crushing treatment, and the open bottom of the crushing box 6 can directly discharge the crushed objects from the crushing box 6; the position where the four-way pipe 8 is installed and connected is located at the bottom end of the crushing box 6, which can cooperate with the two guide plates 905 to guide the sucked sundries, and the guide plate 905 can prevent the sundries from falling into the dead corner of the crushing roller 901, so that the sundries can be crushed smoothly.

[0026] Working principle: Start the fan box 7 and the crushing motor 902. When the corn is peeled, the scattered corn kernels fall into the collecting bucket 2 below. After being filtered by the filter plate 3, the corn kernels enter the storage bucket 4 from the discharge port 10 for storage. Larger branches and leaves impurities are retained on the filter plate 3. The fan box 7 sucks the debris on the filter plate 3 into the crushing box 6 through the four-way pipe 8. The crushing motor 902 drives the worm 903 to rotate. The worm 903 can drive the two worm wheels 904 to rotate inward together. The two worm wheels 904 can drive the two crushing rollers 901 to rotate inward together. With the cooperation of the two crushing rollers 901, the retained branches and leaves can be crushed. , and the crushed branches and leaves are directly discharged from the bottom of the crushing box 6. When the corn kernels accumulated in the storage bucket 4 need to be discharged, a collection bag or a collection bucket is placed at the discharge port, and then the two electric push rods 504 and the discharge motor 503 are started. The electric push rod 504 drives the baffle 505 to move outward and break away from the contact with the surface of the storage bucket 4, thereby releasing the closure of the discharge port. At this time, the corn kernels can flow from the storage bucket 4 into the collecting bag, and the discharge motor 503 can drive the rotating rod 501 to rotate, and the rotating rod 501 can drive the auger blade 502 to rotate in the storage bucket 4.
