Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, specifically to a corn ear conveying and impurity removal device. Background Technology

[0002] Currently, during the process of corn ear harvesters completing ear picking, conveying, and collecting operations in the field in a single operation, a large amount of impurities are often mixed into the harvested corn ears due to the mechanical ear picking and peeling processes, as well as the complexity of the plant morphology in the field. These impurities mainly include broken or fragmented corn leaves, husk fragments, corn silks, dust and fine sand, and corn kernels that have fallen off during ear picking and conveying.

[0003] If the ears are not pre-cleaned before entering the threshing unit, these impurities will enter the threshing process along with the ears, causing further breakage and mixing of impurities during threshing. This significantly increases the impurity content of the subsequent kernels, increases the cleaning load, and affects kernel cleanliness and quality. Therefore, pre-treating the harvested corn ears before threshing to reduce the impurity content is particularly important. Utility Model Content

[0004] This utility model provides a corn ear conveying and impurity removal device to solve the problems mentioned in the background art.

[0005] To address the existing problems, this utility model provides a corn cob conveying and impurity removal device, including a support arm, a bearing beam fixedly connected to the upper end of the support arm, a conveying and filtering assembly connected above the bearing beam via vibration support, a hopper provided above the front end of the conveying and filtering assembly, the side wall of the hopper being fixedly connected to the bearing beam via a connecting plate, and an impurity removal assembly provided below the conveying and filtering assembly, the impurity removal assembly being fixedly connected to the side wall of the bearing beam via a connecting block;

[0006] The conveying and filtering assembly includes a vibrating trough fixedly connected to a vibrating support. Multiple fixed rods are evenly distributed at the bottom of the vibrating trough. Multiple partition plates are evenly arranged at the upper side of the fixed rods and within the vibrating trough. The bottom surfaces of both ends of the fixed rods and the ends of the partition plates are fixedly connected to the bottom of both ends of the vibrating trough. A vibrating motor is installed on the outer wall of the vibrating trough.

[0007] Furthermore, the impurity removal component includes a collection tank disposed below the vibrating tank, a material guide channel is fixedly connected to the lower end of the collection tank, an impurity removal fan is installed on one side wall of the material guide channel, and an impurity discharge port is opened on the other side wall of the material guide channel opposite to the impurity removal fan.

[0008] Furthermore, the conveying and filtering assembly is inclined relative to the horizontal plane to utilize gravity to assist in material conveying.

[0009] Furthermore, the rear end of the vibrating trough is open to facilitate material discharge.

[0010] Furthermore, the length direction of the separator and the fixing rod is parallel to the corn ear conveying direction.

[0011] Furthermore, the vibration motor is a variable frequency motor, and its vibration frequency is adjustable to adapt to corn ears with different moisture contents or impurity contents.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This corn cob conveying and impurity removal equipment consists of a conveying and filtering component and an impurity removal component. During operation, the vibrating trough of the conveying and filtering component vibrates under the action of a vibrating motor. This, combined with the evenly spaced fixed rods at the bottom, creates filtering gaps, separating impurities such as broken leaves, dust, and detached kernels from the corn cob. The fallen impurities enter the feed channel through a collection trough. The directional airflow generated by the impurity removal fan discharges the lighter impurities from the discharge port, while the corn kernels fall below the feed channel for collection. This equipment reduces the impurity content of the corn cob, effectively preventing the problem of increased kernel impurity content during subsequent threshing and reducing the cleaning load on subsequent processing equipment.

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 A corn cob conveying and impurity removal device includes a support arm 1, a bearing beam 2 fixedly connected to the upper end of the support arm 1, a conveying and filtering assembly 4 connected above the bearing beam 2 via a vibration support 3, a feeding hopper 5 disposed above the front end of the conveying and filtering assembly 4, the side wall of the feeding hopper 5 being fixedly connected to the bearing beam 2 via a connecting plate 6, and an impurity removal assembly 7 disposed below the conveying and filtering assembly 4, the impurity removal assembly 7 being fixedly connected to the side wall of the bearing beam 2 via a connecting block 8;

[0022] The conveying and filtering assembly 4 includes a vibrating trough 401 fixedly connected to the vibrating support 3. Multiple fixed rods 402 are evenly distributed at the bottom of the vibrating trough 401. Multiple partition plates 403 are evenly arranged on the upper side of the fixed rods 402 and inside the vibrating trough 401. The bottom surfaces of both ends of the fixed rods 402 and the ends of the partition plates 403 are fixedly connected to the bottom of both ends of the vibrating trough 401. A vibrating motor 404 is installed on the outer wall of the vibrating trough 401.

[0023] It should be noted that the vibration support 3 is existing technology, and its structure and principle will not be described in detail.

[0024] The impurity removal component 7 includes a collection trough 701 located below the vibrating trough 401. A material guide channel 702 is fixedly connected to the lower end of the collection trough 701. An impurity removal fan 703 is installed on one side wall of the material guide channel 702. An impurity discharge port 704 is opened on the other side wall of the material guide channel 702 opposite to the impurity removal fan 703.

[0025] The conveying and filtering assembly 4 is inclined relative to the horizontal plane to utilize gravity to assist in material conveying.

[0026] The rear end of the vibrating trough 401 is open to facilitate material discharge.

[0027] The length direction of the separator plate 403 and the fixing rod 402 is parallel to the direction of corn ear conveying.

[0028] Among them, the vibration motor 404 is a variable frequency motor, whose vibration frequency is adjustable to adapt to corn ears with different moisture content or impurity content.

[0029] It should be noted that the vibrating motor 404 is a variable frequency motor, which can adjust the vibration frequency according to the moisture content or impurity content of the corn ears to ensure the conveying and impurity removal effect under different working conditions. Working principle: During operation, corn ears are fed into the hopper 5 and guided by the hopper 5 into the conveying and filtering assembly 4 below. The conveying and filtering assembly 4 is connected to the bearing beam 2 via the vibrating support 3 and is inclined as a whole. After starting the vibrating motor 404 on the outer wall of the vibrating trough 401, the vibration force generated by the vibrating motor 404 is transmitted to the vibrating trough 401. Due to the inclined setting of the conveying and filtering assembly 4, the corn ears move along the inside of the vibrating trough 401 towards the open rear end. The length direction of the partition plate 403 and the fixing rod 402 is parallel to the conveying direction. The partition plate 403 acts as a separator and guide for the corn ears, separating impurities mixed in with the corn ears. Impurities such as broken leaves, dust, and detached kernels fall through the gaps between the fixed rods 402 during the vibrating conveyor process. The fallen impurities are collected by the collection trough 701 below and then enter the guide channel 702, which is fixedly connected to the collection trough 701. The impurity removal fan 703 on one side of the guide channel 702 continuously blows air to generate a directional airflow, which blows the light impurities in the guide channel 702 out of the discharge port 704 on the opposite side. The heavier corn kernels fall into the collection container placed below the guide channel 702. Finally, the corn ears that have been impurity removed are discharged from the rear end of the vibrating trough 401 to enter the next process, thus completing the entire conveying and impurity removal process.
