Description

Technical Field

[0001] This utility model relates to the field of cotton harvester technology, and in particular to a double-layer chain rake cotton box. 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 collection 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 lot of cotton in the cotton bins. Furthermore, existing cotton bins have limited storage capacity. As harvesting efficiency increases, the cotton storage capacity in the bins remains constant, necessitating frequent unloading, which is quite troublesome. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a double-layer chain rake cotton box that allows for more thorough cotton unloading and a larger cotton storage space.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a double-layer chain rake type cotton box, comprising an upper box body, a lower box body, and a fixed base, wherein the lower box body is mounted on the fixed base, the fixed base is provided with a tilting support rod, the other end of the tilting support rod is mounted in the middle of the lower box body, the bottom plate of the lower box body is provided with a first cotton feeding mechanism, one side of the lower box body is provided with a box door, the box door is provided with a second cotton feeding mechanism, and a lifting mechanism is provided between the upper box body and the lower box body, wherein the upper box body can extend and retract into the lower box body through the lifting mechanism.

[0006] In the above technical solution, the upper box body 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 base is L-shaped, and the tilting support rod is mounted on the bottom rod of the fixed base.

[0011] In the above technical solution, the lower housing can tilt towards the fixed seat side when the tilting support rod is pushed out, and the tilting angle is 0 to 20°.

[0012] In summary, the advantages of this utility model over traditional methods are as follows: This utility model unloads cotton more thoroughly. The cotton in the cotton box is delivered to the outside of the box door via the first and second cotton feeding mechanisms, 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 and facilitating transportation. Attached Figure Description

Detailed Implementation

[0019] Based on the preferred embodiments of this utility model, and through the following description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.

[0020] The present invention will be further described with reference to the following figures:

[0021] like Figures 1-4As shown, a double-layer chain rake type cotton box has an upper box body 100, a lower box body 200, and a fixed base 300. The lower box body 200 is mounted on the fixed base 300. The fixed base 300 is provided with a tilting support rod 310. The extended end of the tilting support rod 310 is installed in the middle of the lower box body 200. The bottom plate of the lower box body 200 is provided with a first cotton feeding mechanism 210. A box door 220 is provided on one side of the lower box body 200. A second cotton feeding mechanism 230 is provided on the box door. A lifting mechanism 400 is provided between the upper box body 100 and the lower box body 200. The upper box body 100 can extend and retract into the lower box body 200 through the lifting mechanism 400.

[0022] like Figure 1 , 2 As shown, the upper box 100 is provided with a cotton inlet 110, and two cotton feeding augers 120 are installed below the cotton inlet 110. The cotton feeding augers 120 are horizontally arranged and parallel to each other. The cotton feeding augers 120 can compact the cotton and prevent the cotton from accumulating at the cotton inlet 110.

[0023] like Figure 1 , 2 As shown, the door 220 is hinged to the lower box body 200, and an opening support rod 221 is provided at the connection.

[0024] Both the first cotton feeding mechanism 210 and the second cotton feeding mechanism 230 are chain rake type conveyor belts.

[0025] The outer surfaces of the upper housing 100 and the lower housing 200 are respectively provided with guide grooves and guide protrusions. The guide grooves and guide protrusions cooperate to provide guidance for the lifting and lowering of the upper housing 100.

[0026] The fixed base 300 is L-shaped, and the tilting support rod 310 is mounted on the bottom rod 320 of the fixed base 300.

[0027] The lower box 200 can tilt towards the fixed seat 300 when the tilting support rod 310 is pushed out, and the tilting angle is 0 to 20°. The reverse tilting makes the cotton drop position higher, which makes it easier to load the cotton directly onto the vehicle and also ensures that the cotton leaves the box in an orderly manner and does not fall outside the cotton loading position.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
