Description

Technical Field

[0001] This utility model relates to the field of cotton harvester technology, and in particular to an external sensing mechanism for lifting cotton box in a cotton harvester and its 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 and finally to the baling bin for packing.

[0003] Our company previously applied for a cotton harvester that can transform by changing the position of the packing box and cotton box, thereby switching between a small-volume transportation state and a large-volume working state. When this cotton harvester is deformed, the cotton box needs a position sensor to detect the deformation state. The existing position sensor is directly set on the cotton box, located at the overlapping position of the upper and lower compartments of the cotton box when it is deformed. When the upper and lower compartments of the cotton box are aligned when the cotton box is deformed, the position sensor can detect the position information. However, in order to ensure that the two parts do not collide during deformation, a certain gap needs to be reserved. However, the sensing distance of traditional position sensors is only 1-3mm, which often results in the sensor failing to detect and cannot be used normally. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide an external sensing mechanism for lifting and lowering the cotton box of a cotton harvester, as well as the cotton box itself, which can greatly improve the accuracy of position detection.

[0005] To solve the above-mentioned technical problems, the first technical solution adopted by this utility model is as follows: an external sensing mechanism for lifting cotton boxes of a cotton harvester, including a connecting rod, a sensing slider and a track, wherein the sensing slider is set in the track and can slide along the track, and position sensors are provided at both ends of the track, and the connecting rod is hinged to the sensing slider.

[0006] In the above technical solution, the two ends of the track are provided with mounting slots, and the position sensor is mounted in the mounting slots.

[0007] In the above technical solution, a wire groove is provided on the back side of the track, and the wiring of the position sensor is arranged in the wire groove.

[0008] To solve the above-mentioned technical problems, the second technical solution adopted by this utility model is as follows: a cotton box for a cotton harvester, having an upper box and a lower box, wherein the lower box is provided with the above-mentioned external sensing mechanism, the track is mounted on the lower box, and the two ends of the connecting rod are respectively connected to the sensing slider and the upper box.

[0009] In the above technical solution, one end of the track is provided with a track seat, and the track is mounted at the bottom of the lower box through the track seat.

[0010] In the above technical solution, the outer end of the connecting rod is provided with a hinge support, and is hinged to the upper box body through the hinge support.

[0011] In the above technical solution, the upper box and the lower box are connected in a four-bar linkage structure by a connecting rod.

[0012] In summary, the advantages of this utility model over traditional technologies are as follows: When the cotton box deforms, the relative positions of the upper and lower boxes change, which in turn drives the sensing slider to move along the track via the connecting rod. When the deformation reaches its limit, the sensing slider approaches the position sensor on the corresponding side, and the position sensor can detect the relevant position information. The entire device is set on the lower box of the cotton bin, and the position change between the boxes does not affect the sensor's signal reception, thus ensuring stable transmission of position signals.
