[0002] Corn, also known as maize, cobs, corn, etc., is native to South America and has been widely spread around the world and has become the globally recognized "golden crop". Corn is not only a common food crop but also a health product among coarse grains, which has many benefits to human health.
[0003] A corn harvester is an agricultural machine used for ear picking, husking, straw returning to the field, etc. when corn is mature. According to different structural forms and functions, corn harvesters can be divided into various models, such as single-row corn harvesters, multi-row self-propelled corn harvesters, ear and stem combined harvesters, etc. The operating efficiency and applicable scope of different models are also different.
[0004] A corn harvester is one of the important and indispensable agricultural machines in modern agriculture, and its efficient and convenient operation method is deeply loved by the majority of farmers. In the related technology, a corn harvester is generally equipped with an engine, ear picking rollers, lifting rods, and dividing devices, etc. However, in some existing harvesters, the dividing device is fixed at a certain place at the front end of the harvesting. Due to different plots and growing environments, the fixed dividing device cannot adapt to all situations, and it may be unable to effectively lift slightly lodged straw or crush the straw. Secondly, since the dividing device is at the front end of the harvester, some straw may be wound around the dividing device, which requires manual shutdown for treatment, reducing the harvesting efficiency.
[0005] Therefore, it is necessary to provide a corn harvester to solve the above technical problems. Summary of the Invention
[0006] The utility model provides a corn harvester, which solves the problem that in the related technology, the dividing device of some existing corn harvesters is not convenient to adjust the height and cannot be cleaned during use, resulting in the inability to exert the dividing effect.

Specific embodiments
[0023] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0024] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , where Figure 1 is a schematic structural diagram of a preferred embodiment of a corn harvester provided by the present utility model; Figure 2 is Figure 1 a schematic structural diagram of the rear view of the harvester main body shown; Figure 3 is Figure 1 a schematic structural diagram of a partial structure of the dividing frame shown; Figure 4 is Figure 3 a schematic structural diagram of the sectional view of the adjusting box shown; Figure 5 is Figure 1 a schematic structural diagram of a partial bottom view of the corn storage box shown. A corn harvester includes: a harvester main body 1, a harvesting assembly 2 is arranged on the right side of the harvester main body 1, and an adjusting assembly 3 is arranged on the right side of the harvesting assembly 2;
[0025] The harvesting assembly 2 includes a horizontal roller ear picking mechanism 21 arranged on the right side of the harvester main body 1, corn storage boxes 22 are arranged on the front and rear sides of the right side of the harvester main body 1 in a mirror image manner, and rotating baffles 23 are rotatably arranged on one side of the two corn storage boxes 22 away from each other;
[0026] By driving the operation of the horizontal roller ear picking mechanism 21 by the harvester main body 1, the corn ears are separated from the straw in cooperation with the lifting frame 25 and the corn ears enter the two internal corn storage boxes 22. After being filled, the rotating baffle 23 can be opened electrically or manually to make the corn ears fall.
[0027] The adjustment component 3 includes a fixed block 31 disposed on the right sides of two corn storage bins 22. The right side of the fixed block 31 is fixedly connected by bolts to an adjustment box 32. A sliding block 33 is slidably disposed up and down on the right side of the adjustment box 32. A dividing rack 34 is disposed on the right side of the sliding block 33.
[0028] Through the setting of the fixed block 31, the dividing rack 34 with different angular shapes can be fixed according to requirements.
[0029] At the bottom of the inner wall of the adjustment box 32, a rotating lead screw 35 is rotatably disposed vertically. Two threaded sleeves 36 are threadedly connected to the peripheral side of the rotating lead screw 35 so as to be movable up and down along its height direction. The right sides of the two threaded sleeves 36 are fixedly connected to the left side of the sliding block 33.
[0030] By rotating the rotating lead screw 35 to drive the two threaded sleeves 36 and the sliding block 33 to move to one side on its peripheral side, thereby causing the dividing rack 34 to move accordingly, the problem of low flexibility of the existing dividing device is solved.
[0031] Sliding frames 37 are disposed at the bottoms of the two corn storage bins 22. A cleaning rack 38 is slidably disposed inside the sliding frames 37. When the cleaning rack 38 slides to the right, it is located at the bottom of the dividing rack 34.
[0032] In order to avoid the problem that the straw is wound around the dividing rack 34 resulting in a reduction in the dividing effect, the protrusion of the cleaning rack 38 is driven by the extension of the output end of the telescopic cylinder 39. Then, the outer side of the cleaning rack 38 will push out the straw wound on the surface of the dividing rack 34 to restore the dividing effect. The telescopic cylinder 39 can continuously reciprocate or be manually controlled.
[0033] The adjustment component 3 further includes a telescopic cylinder 39 disposed on the top of the sliding frame 37. The output end on the front surface of the telescopic cylinder 39 is fixedly connected to the inside of the cleaning rack 38.
[0034] A riding mechanism 24 is disposed on the left side of the harvester main body 1. A lifting rack 25 is disposed on the right side of the top of the harvester main body 1.
[0035] The top end of the rotating lead screw 35 penetrates through the inner wall of the adjustment box 32 and extends to its top. A rotating grip 4 is disposed at the top end of the rotating lead screw 35.
[0036] The working principle of a corn harvester provided by the present utility model is as follows:
[0037] First step: During use, the operation of the horizontal roller ear picking mechanism 21 is driven by the harvester main body 1. In cooperation with the lifting rack 25, the corn ears are separated from the straw and the corn ears enter into the two corn storage bins 22 on both sides. After being filled, the rotating baffle 23 can be opened electrically or manually so that the corn ears fall.
[0038] Step 2: When it is necessary to adjust the height of the corn stalk divider 34 to meet the requirements of dividing different plots of corn stalks, rotate the grip 4 to drive the rotating screw rod 35 to rotate, thereby driving the two threaded sleeves 36 and the sliding block 33 to move to one side on its peripheral surface, and then the corn stalk divider 34 follows the movement, solving the problem of low flexibility of the existing corn stalk divider. During the harvesting process, the reciprocating telescopic movement of the output end of the telescopic cylinder 39 drives the cleaning frame 38 to move back and forth. Then, the outer side of the cleaning frame 38 will push out the corn stalks wound on the surface of the corn stalk divider 34, ensuring the effect of dividing the corn stalks.
[0039] Compared with the related art, a corn harvester provided by the present invention has the following beneficial effects:
[0040] By rotating the grip 4 to drive the rotating screw rod 35 to rotate, thereby driving the two threaded sleeves 36 and the sliding block 33 to move to one side on its peripheral surface, and then the corn stalk divider 34 follows the movement, solving the problem of low flexibility of the existing corn stalk divider. During the harvesting process, the reciprocating telescopic movement of the output end of the telescopic cylinder 39 drives the cleaning frame 38 to move back and forth. Then, the outer side of the cleaning frame 38 will push out the corn stalks wound on the surface of the corn stalk divider 34. The structure is simple and practical, effectively ensuring the effect of dividing the corn stalks and improving the harvesting efficiency in a variable direction.
