Description

Technical Field

[0001] The utility model relates to the technical field of cotton pickers, in particular to a spring conveying mechanism for a picking head of an agricultural cotton picker. Background Art

[0002] A cotton picker is a mechanical device specially used for picking cotton. It is mainly used to strip, collect and clean cotton to improve cotton picking efficiency and reduce manual labor. A cotton picker is usually composed of a cotton stripping device, a conveying device, a cleaning device and a power system, which can automatically complete the cotton picking and processing process. The use of a cotton picker can greatly improve cotton picking efficiency, reduce labor costs, and also reduce cotton losses and improve cotton quality. In the cotton planting industry, a cotton picker is a very important mechanical equipment.

[0003] For example, the patent document with application number 202021625459.8 discloses a cotton picking head conveying mechanism of a cotton picker, including a housing, a motor, a conveying shaft group and a plurality of shifting mechanisms, wherein the housing includes a cotton stripping conveying bin, a cotton conveying sleeve and an air-flow cotton conveying tube connected in sequence; the motor is fixed to the outer end face of the air-flow cotton conveying tube; the conveying shaft group includes a cotton conveying screw and an intermediate shaft connected in sequence, and the cotton conveying screw is arranged in the center of the cotton stripping conveying bin; the intermediate shaft is arranged in the center of the cotton conveying sleeve and passes through the air-flow cotton conveying tube and is connected to the motor; the plurality of shifting mechanisms each include a rotating rod, a micro-stepping motor and a shifting blade, and the cotton conveying sleeve has a plurality of radial slots distributed at equal intervals on opposite sides of the circumference; the rotating rod and the micro-stepping motor driving the rotating rod to rotate are installed in the radial slots; the shifting blade is sleeved on the rotating rod and extends to the inside of the cotton conveying sleeve. The utility model can convey cotton quickly and smoothly without causing damage to it.

[0004] A similar conveying mechanism, during the picking process, due to the lightness and fluffy characteristics of the cotton itself, it is relatively easy to fall off during the picking and processing process, which will cause some cotton to be unable to be effectively picked and fixed. The picking head needs to continuously peel and collect the cotton from the plant during operation, which will cause the cotton to be mixed with soil, weeds and other debris, thereby producing cotton debris, as well as debris and fine fibers. The debris and fibers will fly with the operation of the cotton picker, forming dust, which will cause dust and scaling of the equipment, making the equipment prone to wear and failure.

[0005] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a spring conveying mechanism for a picking head of an agricultural cotton machine is proposed. Utility Model Content

DETAILED DESCRIPTION

[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] like Figures 1 to 4As shown, a spring conveying mechanism for a picking head of an agricultural cotton machine includes a conical head 1, a picking assembly 3, a transmission shaft 4 and an air jet head 10. A fixing plate 2 is arranged on the left side of the conical head 1. The conical head 1 facilitates the cotton machine picking head to pass through a number of cottons and guide the cotton to both sides of the picking head. Two groups of fixing plates 2 are arranged. The two groups of fixing plates 2 support and limit the picking assembly 3 and the transmission shaft 4. A servo motor 5 is arranged in the inner cavity of the conical head 1. The servo motor 5 provides a transmission function and drives the transmission shaft 4 to rotate.

[0023] The picking component 3 is arranged on the opposite surfaces of the two groups of fixed plates 2, and the picking component 3 includes a feeding plate 301, a clamping rod 302 and a widening protrusion 303. The feeding plate 301 is respectively arranged at the upper and lower ends of the opposite surfaces of the two groups of fixed plates 2. The outer surfaces of the two groups of feeding plates 301 are V-shaped, and the two groups of feeding plates 301 correspond to each other in an inverted V shape, ensuring that the picking head applies rotational force to the cotton when rotating, and the cotton is driven into the interior of the picking component 3, and the cotton is guided to the clamping rod 302. The opposite surface between the two groups of feeding plates 301 is provided with a clamping rod 302, and the clamping rod 302 is provided with a plurality of groups. Two groups of the plurality of clamping rods 302 are provided with a widening protrusion 303, and the widening protrusion 303 is provided with There are two groups, and the positions of several groups of clamping rods 302 and widening protrusions 303 are arranged in an equidistant manner. The clamping rods 302 and the widening protrusions 303 are set at a distance according to the size of the cotton. Since the cotton itself is soft, a wider distance is not required. Several cottons are driven into the inner cavity by the force of the material beating plate 301 and the clamping rods 302 through the rotation of the device and contact with the cotton. After being picked, the cotton is restored to its original shape inside the picking component 3 through its own elasticity. When rotating, even if the cotton is not transported away by the threaded belt 41, it will be blocked by the widening protrusion 303 and the clamping rods 302 at a specific distance set to prevent the cotton from falling from the machine during picking.

[0024] A conveying cylinder 6 is arranged on the left side of one group of fixed plates 2. The conveying cylinder 6 is used to provide a channel for conveying cotton. The transmission shaft 4 is arranged at the center of the inner cavity of the conveying cylinder 6. The transmission shaft 4 is connected to the output end of the servo motor 5 by penetrating the two groups of fixed plates 2. The transmission shaft 4 rotates by the kinetic energy provided by the servo motor 5. The outer surface of the transmission shaft 4 is sleeved with a threaded belt 41. The threaded belt 41 provides a conveying and transmission function for cotton. A cotton conveying trough 7 is arranged on the left side of the conveying cylinder 6. The cotton conveying trough 7 is responsible for receiving the cotton transmitted by the conveying cylinder 6 and sending the picked cotton to the subsequent section of the agricultural cotton machine. The end of the transmission shaft 4 away from the cotton conveying trough 7 passes through the two groups of fixed plates 2 in sequence. The fixed plates 2 provide a support function for the transmission shaft 4 and the picking component 3. The two ends of the threaded belt 41 are respectively welded to the two ends of the transmission shaft 4. The threaded belt 41 rotates simultaneously through the rotation of the transmission shaft 4. The outer surface of the threaded belt 41 abuts against the inner surface of the conveying cylinder 6. The threaded edge of the threaded belt 41 fits the conveying cylinder 6 to prevent the cotton from being stuck in the contact surface between the conveying cylinder 6 and it, causing the machine to stop running.

[0025] The outer surface of the right side of the conveying cylinder 6 is provided with a mounting shell 11, and two groups of mounting shells 11 are provided. The two groups of mounting shells 11 are used to fix and install the micro air pump 8. The two ends of the mounting shell 11 are connected to the conveying cylinder 6 by bolts and the fixing plate 2 respectively. The mounting shell 11 is fixed by bolt connection so that the micro air pump 8 can be firmly installed on the device. The inner cavity of the two groups of mounting shells 11 is provided with a micro air pump 8. The micro air pump 8 provides a high-pressure airflow. A nozzle 10 is provided on the right side of one group of fixing plates 2. Two groups of nozzles 10 are provided. The micro air pump 8 is connected to the nozzle 10 through an air pipe 9. The airflow generated by the micro air pump 8 is sent to the nozzle 10 through the air pipe 9. The nozzle 10 uses the high-pressure airflow to clean the cotton debris and residual dust inside the picking component 3 in time, and blow it out to prevent the debris generated when picking cotton from accumulating dust and scaling.

[0026] In summary, if Figures 1 to 4As shown, the spring conveying mechanism of the picking head of the agricultural cotton machine, the conical head 1 guides the cotton to the two sides of the picking component 3 between the two sets of fixed plates 2 when the cotton machine picking head is working, and the cotton machine controls the conveying mechanism of the picking head to rotate as a whole, thereby rotating the picking component 3, and the guided cotton is pulled into its inner cavity through the force of contact between the material beating plate 301 and the clamping rod 302 in the picking component 3 through the rotational force, thereby pulling the cotton into its inner cavity, and the cotton after being picked and entering is restored to its original shape inside the picking component 3 by its own elasticity. When rotating, even if the cotton is not transported away by the threaded belt 41, it will be widened by the protrusion 303 and the clamping rod 30 2 sets a specific distance barrier for cotton to prevent the cotton from falling from the machine during picking. Then the transmission shaft 4 driven by the servo motor 5 rotates at the same time, thereby driving the threaded belt 41 to rotate, and the cotton is sent into the interior of the conveying cylinder 6 through the threaded belt 41 in the picking component 3, and then sent to the cotton conveying trough 7 through the conveying cylinder 6. After the cotton enters the cotton conveying trough 7, it is sent to the subsequent section of the agricultural cotton machine. When dust and debris need to be cleaned, the two groups of micro air pumps 8 in the mounting shell 11 are started, and the high-pressure airflow generated by the micro air pump 8 is sent to the two groups of nozzles 10 through the air delivery pipe 9, so that the high-pressure airflow is blown into the interior of the picking component 3 for cleaning.
