Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of corn harvesters, and in particular to an adjustable corn harvester ear-picking guide mechanism. Background Technology
[0002] A corn harvester is an agricultural implement that mechanically performs multiple tasks in one operation when corn is mature, including ear picking, stacking, and returning the stalks to the field. The process is as follows: The corn harvester picks the ears while the corn is still growing. The ear picking rollers and plates break the ear stalks. Due to the height difference between the inner and outer picking rollers, the ears fall into the ear box. Once the box is full, the ears are opened and piled up. A high-speed rotating cutter cuts the stalks from the root, and the stalks are then shredded into small pieces by a crushing mechanism. After shredding, the stalks fall to the ground naturally. The ears are then transported to the field, where they are hulled by a peeling machine, dried, and threshed.
[0003] The existing Chinese utility model patent with application number CN202120485105.6 relates to a corn harvester ear-picking mechanism, including an output shaft, ear-picking roller, spiral groove, chain, frame and reel, etc. Its structure is simple and practical, its performance is stable and reliable, and it does not have the problem of broken stalks, nor does it "bite" or "bite the tips".
[0004] However, in actual use, the above-mentioned device has a fixed working angle and does not have the ability to adjust the working angle. When operating in rainy weather, the wheels sink, causing the entire vehicle body to fall, making the front working area of the harvester prone to collision with the ground. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides an adjustable corn harvester ear-picking guide mechanism that adjusts the overall elevation angle of the ear-picking part of the equipment through an adjustment device, so that the entire vehicle body sinks down when the equipment is working in soft soil or rainy weather, and the main working area is raised at a certain angle to reduce the collision between the ground and the equipment. A protective device provides protection for the front end of the equipment to reduce the damage caused by ground collisions to the equipment. A material guiding device collects and transports the separated corn ears, thus improving the practicality of the device.
[0006] This utility model discloses an adjustable corn harvester ear-picking guide mechanism, comprising an adjustment device, a protective device, and a material guiding device. The protective device is installed on the adjustment device, and the material guiding device is installed on the adjustment device. The adjustment device adjusts the overall elevation angle of the ear-picking section of the equipment, so that when the equipment is operating in soft soil or rainy weather, the entire vehicle body sinks down and the main working area is raised at a certain angle, reducing collisions between the ground and the equipment. The protective device provides protection for the front end of the equipment, reducing damage caused by ground collisions. The material guiding device collects and transports the separated corn ears, improving the practicality of the device.
[0007] Preferably, the adjusting device includes a connecting frame, guide arms, first rotating shaft seats, hydraulic cylinders, second rotating shaft seats, support arms, and third rotating shaft seats. Multiple sets of first rotating shaft seats are evenly mounted on the upper front face of the connecting frame. The fixed ends of the multiple sets of hydraulic cylinders are respectively connected to the rotating shaft sides of the multiple sets of first rotating shaft seats. Multiple sets of guide arms are provided on the front side of the connecting frame. Multiple sets of second rotating shaft seats are mounted on the upper end faces of the guide arms. The moving ends of the multiple sets of hydraulic cylinders are respectively connected to the rotating shaft sides of the multiple sets of second rotating shaft seats. Multiple sets of support arms are provided on the lower end face of the connecting frame. A third rotating shaft seat is provided on the rear end face of the multiple sets of guide arms. Multiple sets of third pivot seats and multiple sets of support arms are mounted on the lower parts of the support arms via bearings. By controlling the extension of multiple sets of vibration sensors, the guide arms are driven to rotate around the lower part of the connecting frame. This allows the angle of the front end of the multiple sets of guide arms to be adjusted according to the working environment, reducing the possibility of the front part of the guide arms hitting the ground. It also reduces the impact of soft ground and vehicle sinking on the working process in rainy weather. Driven by multiple sets of vibration sensors, the force is evenly distributed, reducing damage to the equipment caused by collisions and improving the practicality of the device.
[0008] Preferably, it also includes a tension sensor, which is installed on the moving end of the hydraulic cylinder; by using the tension sensor installed on the moving end of the hydraulic cylinder to monitor the tension on the moving ends of multiple hydraulic cylinders, it prevents excessive tension on a single hydraulic cylinder from causing equipment damage and improves the practicality of the device.
[0009] Preferably, the device also includes a guide chain, a feeding roller, and a cutting blade. A set of guide chains is respectively installed on the left and right sides of the guide arm. The guide chains are driven by a motor and a sprocket. A set of feeding rollers is respectively installed on the lower part of the left and right sides of the guide arm. The feeding rollers are driven by a motor. A cutting blade is installed on the lower end face of the guide arm. The cutting blade can extend into the area between two adjacent sets of guide arms. The cutting blade is driven by a motor. The rotating guide chain, in conjunction with the guide arm, guides the corn stalk. The rotating feeding roller drives the corn stalk to move downward. The rotating cutting blade cuts the corn stalk, improving the practicality of the device.
[0010] Preferably, the protective device includes a protective plate, a wear-resistant welding rod, and a vibration sensor. A set of protective plates is respectively provided on the upper and lower front end face of the guide arm. A wear-resistant welding rod is provided on the lower end face of the lower protective plate, and a vibration sensor is installed on the front end face of the protective plate. The upper and lower sets of protective plates provide protection for the front end face of the guide arm, reducing damage caused by friction between the connecting frame and the ground. The wear-resistant welding rod on the lower end face of the protective plate reduces friction loss between the ground and the lower protective plate. The vibration sensor detects the vibration intensity on the front end face of the guide arm, making it easier for operators to detect impacts to the front of the guide arm in a timely manner, thus improving the practicality of the device.
[0011] Preferably, the feeding device includes a reducer, a motor, bidirectional spiral blades, and a discharge hole. A reducer is installed on the left side of the multiple guide arms, and a motor is installed on the reducer. The bidirectional spiral blades are installed on the rear of the multiple guide arms via a bracket, and a discharge hole is provided at the lower middle position of the bracket. When the motor is turned on, the power is transmitted to the bidirectional spiral blades through the reducer, which drives the bidirectional spiral blades to rotate, thereby transporting the corn ears conveyed between the multiple guide arms to the center and discharging them centrally through the discharge hole, which facilitates the collection of corn fragments and improves the practicality of the device.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by adjusting the overall elevation angle of the ear-picking part of the equipment through the adjustment device, the entire vehicle body sinks down when the equipment is working in soft soil or rainy weather, and the main working area is raised at a certain angle, reducing the collision between the ground and the equipment. The protective device provides protection for the front end of the equipment, reducing the damage to the equipment caused by ground collisions. The separated corn ears are collected and transported through the material guiding device, which improves the practicality of the device. Attached Figure Description
