Description

Technical Field

[0001] This utility model relates to the field of cotton harvester technology, and in particular to a multi-row cotton harvester. Background Technology

[0002] Cotton cultivation is widespread in my country. Previously, cotton harvesting relied primarily on manual labor, which was labor-intensive and inefficient. With the continuous improvement of agricultural mechanization in my country, large-scale mechanized cotton harvesting has become an inevitable trend in the cotton industry, leading to the emergence of cotton harvesters on the market. Using cotton harvesters can effectively increase harvesting speed and generate higher incomes for cotton harvesters. The main structure of a cotton harvester includes a frame, a harvesting head, a cotton collection bin, and a baling bin. During operation, the harvesting head collects cotton, which is then transported to the cotton bin. Once harvesting is complete or the bin is full, the cotton is unloaded.

[0003] Existing cotton harvesters typically unload cotton by tilting the cotton bins and pouring the cotton directly out. This method relies solely on gravity to remove the cotton from the bins, but it often results in incomplete unloading, leaving a significant amount of cotton residue in the cotton bins. Furthermore, existing cotton bins have limited storage capacity. As harvesting efficiency increases, the cotton bin storage capacity remains constant, necessitating frequent unloading, which is extremely inconvenient. Moreover, the connection between the cotton bins and the cotton conveying pipes after each unloading process is also quite troublesome. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a multi-row cotton harvester that allows for more thorough unloading of cotton from cotton boxes and provides a larger cotton storage space.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A multi-row cotton harvester has a frame, a harvesting head assembly at the front end of the frame, a cotton box on the frame, the harvesting head assembly connected to the cotton box via a cotton conveying pipe, the cotton box having an upper box body, a lower box body, and a fixed seat, the lower box body mounted on the frame via the fixed seat, a tilting support rod on the fixed seat, the other end of the tilting support rod mounted in the middle of the lower box body, a first cotton feeding mechanism on the bottom plate of the lower box body, a box door on one side of the lower box body, a second cotton feeding mechanism on the box door, a box body lifting device between the upper and lower box bodies, the upper box body extending and retracting into the lower box body via the box body lifting device, the cotton conveying pipe mounted on a cotton conveying pipe frame, a pipe frame lifting device mounted on the cotton conveying pipe frame, the pipe frame lifting device pushing the cotton conveying pipe frame and driving the cotton conveying pipe to rise and fall.

[0006] In the above technical solution, the upper box is provided with a cotton inlet, and two cotton feeding augers are installed below the cotton inlet. The cotton feeding augers are horizontally arranged and parallel to each other.

[0007] In the above technical solution, the box door is hinged to the lower box body, and a door opening support rod is provided at the connection point.

[0008] In the above technical solution, both the first cotton feeding mechanism and the second cotton feeding mechanism are chain rake type conveyor belts.

[0009] In the above technical solution, guide grooves and guide protrusions are respectively provided on the outer surfaces of the upper box and the lower box.

[0010] In the above technical solution, the fixed seat is L-shaped, the tilting support rod is mounted on the bottom rod of the fixed seat, and the lower box can tilt towards the fixed seat side when the tilting support rod is pushed out, and the tilting angle is 0 to 20°.

[0011] In the above technical solution, a wheel-side motor is provided on the inner side of the wheel on the frame, and is driven by the wheel-side motor.

[0012] In the above technical solution, an engine is horizontally mounted on the lower part of the frame, and the engine's air outlet faces both sides of the frame.

[0013] In the above technical solution, the front end of the vehicle frame is provided with a cotton harvesting head frame, the cotton harvesting head frame is provided with multiple adjusting screw holes, the cotton harvesting head is bolted to the adjusting screw holes on the cotton harvesting head frame, and the cotton harvesting head frame is equipped with four cotton harvesting heads.

[0014] In the above technical solution, both the pipe rack lifting device and the box lifting device are hydraulically driven struts.

[0015] In summary, the advantages of this utility model over traditional methods are as follows: This utility model unloads cotton more thoroughly. The first and second cotton feeding mechanisms deliver the cotton from the cotton box to the outside of the box, resulting in more complete unloading. The double-layer structure of the upper and lower boxes allows the upper box to rise under the drive of the lifting mechanism when the cotton harvester is working, providing a larger cotton storage space. When not in operation, the upper box can retract into the lower box, reducing the overall height and volume of the cotton box for easier transportation. The unloading position can be accurately controlled. Upon completion of unloading and resetting the cotton box, the pipe rack lifting device can push the cotton conveying pipe rack to accurately connect with the cotton inlet. After connection, the cotton is normally transported into the cotton box under the action of wind, restoring normal operation. Attached Figure Description
