Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, and in particular relates to a corn kernel harvesting device that facilitates the removal of leaves. Background Technology

[0002] The core component of a corn harvester header is the ear-picking device, whose performance directly determines key indicators such as harvesting efficiency, loss rate, and grain breakage rate. Currently, the mainstream technologies are divided into two types: ear-picking roller type and ear-picking plate type. The ear-picking roller type device uses a pair of opposing rotating rollers to forcefully pull the stalk and uses the ear-picking plate above to block the ears, thus achieving separation. Its technology is mature and widely adaptable; however, the ear-picking device of a corn harvester header still has the following drawbacks in actual use: When the corn harvester's header and ear-picking device is in operation, it directly pulls the corn stalks to harvest them. During the production process, pulling the corn stalks can cause them to tilt and deviate from the ear-picking position, affecting the accuracy of ear picking. Secondly, during the operation of the corn harvester's header ear-picking device, the corn ears need to be transported to the subsequent storage location. During the ear-picking process, some corn leaves will be scraped off and transported to the corn ear storage equipment along with the corn ears, affecting the effective storage capacity of the corn ears. Utility Model Content

[0003] The purpose of this utility model is to provide a corn kernel header ear-picking device that facilitates the removal of leaves. By setting up a conveying frame, a connecting frame, a fan, and a fixing block, it solves the problem that the corn harvester header ear-picking device does not guide the corn plants well enough, and that corn leaves are easily mixed in and transported to the storage equipment during the ear-picking process.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a corn kernel harvesting device for convenient leaf removal, comprising a conveying frame, a connecting frame, fans, and fixing blocks. The conveying frame is L-shaped, and a connecting plate is fixed at one L-shaped corner inside the conveying frame. A fixing opening is provided in the connecting plate, and several fans are fixed in the fixing opening. The output end of the fans faces the inside of the connecting frame. The connecting frame is fixed to one end of the conveying frame, and a fixing plate is fixed to the bottom of the connecting frame. Fixing blocks are fixed to both short sides of the fixing plate. The conveying frame has an L-shaped structure, and multiple fans are fixed to its inner corner through the connecting plate. The air outlet of the fans faces the inside of the connecting frame. One end of the conveying frame is connected to the connecting frame, and a fixing plate is installed at the bottom of the connecting frame. A fixing block is installed on each of the two short sides of the fixing plate for supporting and connecting transmission components.

[0005] Furthermore, guide blocks are symmetrically fixed on the end face of the conveying frame away from the connecting frame, and an opening is provided in the conveying frame between the two guide blocks. Two guide blocks are symmetrically arranged at the end of the conveying frame, with an opening between them, for guiding the corn plants into the conveying frame.

[0006] Furthermore, fixing strips are symmetrically fixed inside the opening of the conveying frame, and connecting strips are fixed at the corner of the bottom of the conveying frame away from the fixing plate. Fixing strips are symmetrically fixed inside the opening for removing corn ears. Connecting strips are installed at the bottom corner of the conveying frame to achieve leaf separation in conjunction with the airflow of the fan.

[0007] Furthermore, a fixing net is fixed at both edges of the inner wall of the fan. The fan is set inside the conveying frame, and fixing nets are installed at both the inlet and outlet of the fan to protect the internal fan blade structure and prevent impurities from entering.

[0008] Furthermore, a drive shaft is movably connected through the fixed block, and a connecting roller is fixed to one end of each drive shaft. The two connecting rollers are symmetrically arranged. A drive shaft is installed through the fixed block, and a connecting roller is connected to each shaft end. The two rollers are symmetrically arranged and are driven to rotate in opposite directions by external power.

[0009] Furthermore, both connecting rollers are fixed with helical blades on their periphery. The two helical blades are symmetrically arranged. Each connecting roller is equipped with a helical blade on its outer periphery. The two blades rotate symmetrically, so as to clamp and transport the corn plants during the opposite rotation process.

[0010] This utility model has the following beneficial effects: This invention solves the problem of insufficient guidance of corn plants by the header ear-picking device of a corn harvester by setting up a conveyor frame and fixing blocks. As the connecting rollers rotate, they drive the spiral blades to rotate. Through the movement of the harvester, the corn plants move between the two connecting rollers. The rotation of the connecting rollers guides the plants to the two guide blocks, which then guide them into the opening on the conveyor frame. The fixing strip, along with the rotating connecting rollers and their spiral blades, pulls the corn plants, causing the corn ears to be picked. After picking, the ears are directly guided through the conveyor frame to the connecting frame, and then transported to the subsequent harvesting steps. This improves the guidance of the corn plants by the header ear-picking device of the corn harvester.

[0011] This invention solves the problem of corn leaves easily getting mixed in during the ear-picking process of a corn harvester by setting up a conveyor frame, a connecting frame, and a fan. During the ear-picking process, the corn ears are conveyed into the conveyor frame, and then conveyed to the connecting frame under the inclined conveyor frame. From there, they are conveyed to the subsequent production equipment of the harvester. As the corn ears pass through the conveyor frame, the fan draws in air and blows it out onto the connecting strip inside the conveyor frame before exiting the conveyor frame. This results in fewer broken leaves remaining when the corn ears are collected during harvesting, thus improving the quality of ear picking. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation

[0016] Please see Figure 1-4This utility model relates to a corn kernel harvesting device for convenient leaf removal, comprising a conveying frame 1, a connecting frame 2, a fan 3, and a fixing block 4. The conveying frame 1 is L-shaped and inclined upward on the connecting frame 2. A connecting plate 101 is fixed at an L-shaped corner inside the conveying frame 1. The fan 3 is connected to the conveying frame 1 through the connecting plate 101. The conveying frame 1 conveys the harvested corn ears. A fixing opening 1011 is provided in the connecting plate 101, through which the connecting plate 101 is fixed. Fan 3, a number of fans 3 are fixed inside the fixed port 1011. The output end of the fans 3 is set facing the inside of the connecting frame 2. The fans 3 blow air into the conveying frame 1. The connecting frame 2 is fixed to one end of the conveying frame 1. The connecting frame 2 outputs the corn ears in the conveying frame 1 to the subsequent production steps. The bottom of the connecting frame 2 is fixed with a fixing plate 201. Fixing blocks 4 are fixed on both short sides of the fixing plate 201. The fixing plate 201 connects the fixing blocks 4 to it. The drive shaft 401 is connected in it through the fixing blocks 4.

[0017] Specifically, guide blocks 102 are symmetrically fixed on the end face of the conveying frame 1 away from the connecting frame 2. An opening 103 is opened in the conveying frame 1 between the two guide blocks 102. The conveying frame 1 guides the corn plants into the opening 103 of the conveying frame 1 through the guide blocks 102.

[0018] Furthermore, fixing strips 104 are symmetrically fixed inside the opening 103 inside the conveying frame 1, and connecting strips 105 are fixed at the corner of the bottom of the conveying frame 1 away from the fixing plate 201. The conveying frame 1 uses the fixing strips 104 to pick the corn ears from the corn plants that enter the opening 103, and uses the connecting strips 105 to limit the corn ears passing through the conveying frame 1 to prevent the corn ears from being blown out.

[0019] Furthermore, a fixing net 301 is fixed at both edges of the inner wall of the fan 3. The fan 3 is set inside the conveying frame 1. The fan 3 protects the blowing structure inside the fan 3 through the fixing net 301. The blowing structure blows air into the conveying frame 1 and blows the corn leaves off the corn after the ears are picked.

[0020] The operation process of this embodiment is as follows: During the harvesting process, the corn ears are conveyed into the conveying frame 1 and then conveyed into the connecting frame 2 under the inclined conveying of the conveying frame 1. The corn ears are then conveyed into the subsequent production equipment of the harvester in the connecting frame 2. When the corn ears pass through the conveying frame 1, the fan 3 draws in air and blows it out onto the connecting strip 105 in the conveying frame 1 and outputs it out of the conveying frame 1. This makes it possible to have less broken leaves remaining when the corn ears are collected during the harvesting of corn. Specific Implementation

[0021] Please see Figure 1-5Based on the first specific embodiment, a drive shaft 401 is movably connected through the fixed block 4. One end of each drive shaft 401 is fixed with a connecting roller 402. The two connecting rollers 402 are arranged symmetrically to each other. The fixed block 4 connects the drive shaft 401 therein. The drive shaft 401 drives the connecting roller 402 to rotate, and the rotating connecting roller 402 drives the spiral blade 403 to rotate.

[0022] Specifically, spiral blades 403 are fixed on the periphery of both connecting rollers 402. The two spiral blades 403 are arranged symmetrically to each other. The two connecting rollers 402 rotate in opposite directions during operation, so that the spiral blades 403 drive the corn plants to be transported as they rotate.

[0023] The operation process of this embodiment is as follows: During operation, the output end of the drive structure on the harvester is fixed to two transmission shafts 401. The fixing block 4 is connected to the harvester. The drive structure on the harvester drives the transmission shafts 401 to rotate, which in turn drives the connecting rollers 402 to rotate. As the connecting rollers 402 rotate, the spiral blades 403 rotate. Through the movement of the harvester, the corn plants move between the two connecting rollers 402. Through the rotation of the connecting rollers 402, the plants are guided to be placed between the two guide blocks 102. The guide blocks 102 guide the plants to the openings 103 on the conveying frame 1. The fixing strip 104 pulls the corn plants as the connecting rollers 402 and the spiral blades 403 rotate, so that the corn ears on the corn plants are picked. After picking, the corn ears are directly guided and conveyed to the connecting frame 2 through the conveying frame 1, and then conveyed to the subsequent harvesting steps through the connecting frame 2.
