Description

Technical Field

[0001] The utility model relates to the technical field of cotton pickers, in particular to a cotton conveying pipe regulating device for a cotton picker. Background Art

[0002] After the cotton is picked by the cotton picking head, it is transported to the cotton box through the cotton transport pipe. This process mainly relies on the pneumatic cotton transport system, in which the airflow generated by the high-speed centrifugal fan transports the picked cotton to the destination through the pipe. The existing cotton picker cotton transport pipe uses airflow to transport the picked cotton to the cotton box quickly and with low damage, and there are many technical improvements in this regard. However, after the cotton passes through the cotton transport pipe, it collides with the cotton box hood to guide the cotton into the cotton box. The friction between the cotton and the hood is large, and the cotton does not pass smoothly. The air duct and the hood are fixed and the angle cannot be adjusted. The cotton is easy to fall from the hood inlet, affecting the work harvesting efficiency. Utility Model Content

[0003] The purpose of the utility model is to provide a cotton conveying pipe adjustment device for a cotton picker to solve the deficiencies of the above-mentioned prior art. The technical problem to be solved by the utility model is to reduce the collision between cotton and the wind hood of the cotton box, so that the cotton can enter the cotton box more smoothly and the harvesting efficiency can be improved.

[0004] A cotton conveying pipe adjustment device for a cotton picker comprises: a pressure plate, an air duct elbow, a hinge, and a locking bolt. One end of the air duct elbow and an outlet end of the cotton conveying pipe are connected by a hinge, and the other end of the air duct elbow is fitted with a cotton box hood. One end of the pressure plate is fixed to the air duct elbow, and the other end of the pressure plate is pressed onto the outlet end of the cotton conveying pipe, and a screw hole is provided at this end. An arc groove is provided on the pressure plate, and the locking bolt is inserted into the arc groove and leaves a certain gap with the groove wall of the arc groove. The screw rod part of the locking bolt is fitted with the screw hole.

[0005] Preferably, there are two locking bolts, two screw holes are provided on the port of the cotton conveying tube, and two rows of arc grooves are provided on the pressure plate. The two locking bolts are respectively inserted into their corresponding arc grooves, and a certain gap is left with the groove wall of the arc groove. The screw parts of the two locking bolts are matched with the corresponding screw holes.

[0006] Preferably, a hanging plate is provided on the other end of the air duct elbow, and a convex plate is provided in the cotton box hood, and the hanging plate and the convex plate can be hung and arranged.

[0007] Preferably, the air duct elbow is a corrugated tube.

[0008] Beneficial effects of the utility model:

[0009] The utility model adds an air duct elbow at one end of the outlet of the cotton conveying pipe, and the two are connected by a hinge to form a new cotton outlet. The air duct elbow is rotated to adjust the fitting angle between the air duct elbow and the cotton box hood, thereby reducing the impact of cotton, making the cotton enter the cotton box more smoothly, and improving the harvesting efficiency. The locking bolt and the pressure plate can be used to flexibly adjust the angle of the newly formed cotton outlet and fix it, which is conducive to the close fitting between the air duct elbow and the cotton box hood, so that the cotton can enter the cotton box smoothly.

[0013] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0014] Figure 1-2 A cotton conveying pipe adjusting device for a cotton picker is shown, comprising a pressure plate 2, an air duct elbow 3, a hinge 4, and a locking bolt 6. One end of the air duct elbow 3 and the outlet end of the cotton conveying pipe 1 are connected with a hinge, and the other end of the air duct elbow 3 is fitted with a cotton box hood 7. One end of the pressure plate 2 is fixed on the air duct elbow 3, and the other end of the pressure plate 2 is pressed on the outlet end of the cotton conveying pipe 1, and a screw hole is provided at this end. An arc groove 5 is provided on the pressure plate 2, and the locking bolt 6 is inserted into the arc groove 5, and a certain gap is left with the groove wall of the arc groove 5. The screw part of the locking bolt 6 is matched with the above-mentioned screw hole. The locking bolt 6 can slide smoothly in the trajectory of the arc groove 5, so that the rotation between the air duct elbow 3 and the outlet end of the cotton conveying pipe 1 is smoother. By adding an air duct elbow at one end of the outlet of the cotton conveying pipe, the two are connected by a hinge to form a new cotton outlet, and the air duct elbow is rotated to adjust the fitting angle between it and the cotton box hood, thereby reducing the impact of cotton, making the cotton enter the cotton box more smoothly, and improving the harvesting efficiency. By tightening the bolt 6 and the pressing plate 2, the angle of the newly formed cotton outlet can be flexibly adjusted and fixed, which is conducive to the close fit between the air duct elbow 3 and the cotton box hood 7, so that the cotton can enter the cotton box smoothly.

[0015] In order to further improve the rotation stability between the duct elbow and one end of the cotton conveying pipe outlet, it is advisable to set the number of locking bolts 6 to two, provide two screw holes on the port of the cotton conveying pipe 1, and provide two rows of arc grooves 5 on the pressure plate 2. The two locking bolts 6 are respectively inserted into their corresponding arc grooves 5, and a certain gap is left with the groove wall of the arc groove 5. The screw parts of the two locking bolts 6 are matched with the corresponding screw holes.

[0016] In order to make the air duct elbow 3 and the cotton box hood 7 tightly fixed after being attached to each other, as an embodiment of the utility model, it is envisaged to adopt a hanging fixation. Figure 2 A hanging plate 10 is provided on the other end of the air duct elbow 3, and a convex plate 11 is provided in the cotton box hood 7. The hanging plate 10 and the convex plate 11 can be hung and arranged.

[0017] For the duct elbow 3, sheet metal processing can be used, which is wear-resistant, practical and reliable. A corrugated tube can also be used, which can adjust the fitting angle between it and the cotton box hood, making the adjustment more flexible.

[0018] Working principle of this utility model:

[0019] After the cotton is picked by the numbered cotton picking head 8, it is transported to the duct elbow 2 through the cotton delivery pipe 1. Loosen the locking bolt 6. Since the pressing plate 2 is fixed to the duct elbow 3, the duct elbow 3 and the cotton delivery pipe 1 are connected by a hinge, turn the pressing plate 2, adjust the angle of the duct elbow 3, and make the outlet of the duct elbow 3 fit closely with the cotton box hood 7. At this time, hang the hanging plate 10 on the convex plate 11 in the cotton box hood 7, and then tighten the locking bolt 6 to lock the pressing plate 2. After completing the above operations, the cotton will enter the cotton collection box 9 more smoothly through the cotton delivery pipe 1.

[0020] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
