Description

Technical Field

[0001] This utility model relates to the field of corn harvester technology, specifically to a multi-stage cleaning vibrating screen device for corn harvesters. Background Technology

[0002] A corn harvester is an agricultural machine that uses machinery to complete multiple tasks such as picking ears, piling up, and returning stalks to the field in one go when the corn is ripe. However, the harvested corn needs to be cleaned and sorted during the process.

[0003] Chinese patent discloses a cleaning and vibrating screening device, publication number CN210641426U, comprising: a bent bottom plate for receiving sieved fruits and sieved fine stems; a vibrating screen mechanism for conveying unsieved coarse stems; and an adjusting mechanism; the vibrating screen mechanism is provided on the upper part of the bent bottom plate, and the sieving end of the bent bottom plate and the vibrating screen mechanism forms a straw outlet channel for conveying sieved fine stems; the adjusting mechanism is disposed between the bent bottom plate and the sieving end to adjust the cross-sectional area of ​​the straw outlet channel on the side away from the bent bottom plate. This invention ensures that the size of the cross-sectional area at the end of the straw outlet channel matches the wind speed of the straw-lifting fan used to blow the sieved fine stems into the straw box, thereby guaranteeing the cleaning capacity of the cleaning and vibrating screen device, avoiding fruit waste, and reducing the impurity rate of the fruit.

[0004] However, it still has the following drawbacks: it cannot quickly clean the internal screening components, which can easily lead to clogging and affect corn screening. To address this issue, we propose a multi-stage cleaning vibrating screen device for corn harvesters. Utility Model Content

[0005] The purpose of this invention is to provide a multi-stage cleaning vibrating screen device for corn harvesters to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

Two first limiting grooves are formed through the side of the U-shaped plate. The inner walls of the two first limiting grooves are rotatably provided with reciprocating threaded rods through bearing seats. The outer surfaces of the two reciprocating threaded rods are threaded with first sliders. Placement boxes are fixedly installed on the sides of the two first sliders. The lower end surfaces of the output rods of the two first motors are fixedly connected to the upper end surfaces of the two reciprocating threaded rods.

[0010] The vibration assembly includes a feed inlet, the bottom surface of which is fixedly connected to the top surface of the placement box.

The outer surface of the spiral blade contacts the inner wall of the feed inlet. A door is hinged to the front of the placement box.

[0011] A further improvement is that the cleaning mechanism includes two first filter boxes, which are respectively located inside the placement box. Several support boxes are fixedly installed on the inner wall of the placement box, and a first groove is opened through the side of each of the several support boxes.

[0012] A further improvement is that a first damper is fixedly installed on the inner wall of each of the first grooves, an L-shaped plate is slidably arranged on the inner wall of each of the first grooves, and the bottom surface of each of the first dampers is fixedly connected to the top surface of each of the L-shaped plates.

[0013] A further improvement is that several L-shaped plates are respectively fixedly installed on the outer surfaces of the two first filter boxes by several bolts, and two first support plates are fixedly installed on the inner wall of the placement box, and several second dampers are fixedly installed on the bottom surfaces of the two first support plates.

[0014] A further improvement is that a second support plate is fixedly installed on the top surface of several second dampers, and the top surface of several second support plates is respectively in contact with the bottom surface of the first filter box located above.

[0015] A further improvement is that a number of third dampers are fixedly installed on the inner wall of the placement box, a sewage outlet pipe is opened through the bottom surface of the placement box, a third support plate is fixedly installed on the top surface of the number of third dampers, the top surface of the third support plate is respectively in contact with the bottom surface of the first filter box located below, and a water outlet pipe is opened through the bottom surface of the placement box.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the corn harvester uses a multi-stage cleaning vibrating screen device, which uses a vibration mechanism and a first motor to drive the reciprocating threaded rod to rotate, thereby performing multiple screening operations on the corn inside the box. The detachable first filter box facilitates the cleaning of the inside of the box.

[0017] By setting up a cleaning mechanism and moving the L-shaped plate by setting up the first damper, when it is necessary to clean the corn, the third support plate drives the second damper to move up and down, thereby mixing the corn kernels inside the box. Through the up and down vibration, the corn is quickly cleaned, making it easy to store. Attached Figure Description
