Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and in particular to a double-air-path pneumatic ground-type red date picking machine. Background Art

[0003] As the red dates industry has entered its peak fruit-bearing period after years of cultivation, red dates harvesting has become a major problem facing farmers. At present, the traditional way of harvesting red dates is to pick them up manually on the ground, which is labor-intensive, high in labor costs, and slow in harvesting. There are a small number of prototypes in use on the market, but they all use straws as picking suction ports. During the picking process, people need to carry the straws to complete the picking of fallen red dates. The machine cannot move continuously and adopts a progressive harvesting operation method, which has low work efficiency.

[0004] Therefore, it is urgent to design a fallen red date picking, cleaning and harvesting machine and a matching double-suction picking head for mechanized fallen red date picking and harvesting, which can increase the picking operation width and reduce labor cost investment, so as to solve the problems of high labor intensity, low efficiency and high picking cost in the process of manual picking of red dates and the need for multiple people to operate the existing prototype. Summary of the invention

[0015] The present invention is further configured as follows: the driving machine comprises a supporting chassis and a supporting frame, the supporting frame is welded to the top of the supporting chassis, and hydraulic crawler drive structures are arranged on both sides of the bottom of the supporting chassis.

[0016] By adopting the above technical scheme, through the setting of driving equipment, the structural design of the supporting chassis and the supporting frame provides solid support for the entire picking machine, ensuring the stability of the machine during the process of picking, cleaning and transporting red dates, and reducing problems such as missing red dates or incomplete cleaning due to machine shaking. The hydraulic crawler drive structure gives the machine good off-road performance and flexible controllability, can adapt to the complex terrain conditions of red date planting areas, and improves the applicability and operating range of the machine.

[0018] By adopting the above technical scheme, the adaptability of the picking device to the ground is enhanced through the articulation of the dual air-circuit picking device and the driving machine, which can better capture the fallen red dates and improve the picking efficiency. The stable installation of the cleaning device and the centrifugal fan on the supporting frame ensures the normal progress of the cleaning work, is conducive to the stable operation of the air-circuit system, and reduces problems such as unstable suction caused by equipment shaking.

[0020] By adopting the above technical solution and setting up a dual air-circuit picking device, the hydraulic lifting mechanism can accurately adjust the height of the picking suction port according to different working scenarios and ground conditions, thereby improving the adaptability of the picking machine, reducing the need for manual intervention, and improving the machine's degree of automation and operating efficiency. In addition, a dual-pipeline dual-suction port design is adopted to increase the one-time operating width, effectively improving operating efficiency.

[0027] The adoption of the above technical solution helps to improve the accuracy and balance of picking red dates through the design of the date collecting structure and the diversion baffle. By initially gathering the red dates and adjusting the flow rate, the two picking suction ports can more effectively capture the red dates and reduce omissions. The supporting roller structure enhances the adaptability of the picking suction port and the date collecting structure to the ground, and improves the picking stability and reliability of the machine under different terrain conditions.

[0029] By adopting the above technical scheme, the coordinated adjustment of the two is achieved by setting up a hydraulic lifting mechanism and an articulated mode of the date collecting structure. During the operation of the machine, whether the picking height needs to be adjusted due to changes in terrain, or the posture of the picking device needs to be changed in different operation stages (such as picking and transferring), the synchronous movement of the picking suction port and the date collecting structure can be guaranteed, which improves the continuity and stability of the operation and reduces problems such as operation interruption or scattering of red dates due to equipment adjustment.

The hinged connection between the dual-air-circuit picking device 1 and the driving machine 2 enhances the adaptability of the picking device to the ground, and can better capture the fallen red dates, thereby improving the picking efficiency. The stable installation of the cleaning device 3 and the centrifugal fan 5 on the supporting frame 22 ensures the normal progress of the cleaning work, is conducive to the stable operation of the air circuit system, and reduces problems such as unstable suction caused by equipment shaking.

[0047] Among them, the dual-air-circuit picking device 1 includes two picking suction ports 11, the top of the picking suction port 11 is connected to a conveying hose 12, and the other end of the conveying hose 12 is connected to the inlet of the cleaning box 31, and a hydraulic lifting mechanism 13 is arranged between the tops of the two picking suction ports 11, and the hydraulic lifting mechanism 13 is hinged to the supporting chassis 21 and the supporting frame 22 on one side thereof.

In addition, the dual-pipeline dual-suction port design is adopted to increase the one-time working width and effectively improve the working efficiency.

[0048] The driving machine 2 is provided with a diesel engine, a hydraulic pump and a multi-way reversing valve, and the output end of the diesel engine is connected to the hydraulic pump, and the centrifugal fan 5, the bar conveying device 4 and the cleaning device 3 are all provided with a driving end on one side;

[0049] Among them, the output end of the multi-way reversing valve is connected to the hydraulic lifting mechanism 13, the driving end and the hydraulic crawler driving structure 23 through pipelines respectively. The diesel engine provides power to the hydraulic pump, and the multi-way reversing valve controls the hydraulic motor and the hydraulic cylinder to realize the movement of the whole machine and the rotation and lifting of the device, so that the whole machine can be operated by only two people, and the controllability and operating performance of the entire picker are improved.

[0051] Among them, a jujube collecting structure 9 is arranged on the front side of the picking suction port 11, and the two jujube collecting structures 9 are connected by a diversion baffle. Support roller structures are arranged on both sides of the picking suction port 11 and the jujube collecting structure 9. The design of the jujube collecting structure 9 and the diversion baffle helps to improve the accuracy and balance of picking up red dates. By initially gathering the red dates and adjusting the flow rate, the two picking suction ports 11 can more effectively capture the red dates and reduce omissions. The support roller structure enhances the adaptability of the picking suction port 11 and the jujube collecting structure 9 to the ground, and improves the picking stability and reliability of the machine under different terrain conditions.

[0052] Among them, one end of the hydraulic lifting mechanism 13 is hinged to the jujube collecting structure 9. By setting the hinge mode of the hydraulic lifting mechanism 13 and the jujube collecting structure 9, the coordinated adjustment of the two is realized. During the operation of the machine, whether it is the need to adjust the picking height due to terrain changes, or the need to change the posture of the picking device in different operation stages (such as picking and transferring), the synchronous action of the picking suction port 11 and the jujube collecting structure 9 can be guaranteed, which improves the continuity and stability of the operation and reduces the problems of operation interruption or scattering of red dates caused by equipment adjustment.

[0053] The working principle of this embodiment is as follows: first, the height and inclination angle of the jujube blocking plate 33 are adjusted according to the use requirements, and the guiding angle of the guide plate 34 is adjusted. Then, the control console 6 controls the hydraulic lifting mechanism 13 to lower the picking suction port 11 of the dual-air path picking device 1 so that it is close to the ground. At the same time, the jujube collecting structure 9 is also close to the ground under the action of the supporting roller structure, ready for the jujube picking operation. Subsequently, the centrifugal fan 5 is started to form a negative pressure at the picking suction port 11 of the dual-air path picking device 1. As the hydraulic crawler drive structure 23 moves forward, the picking suction port 11 is moved forward. The date collecting structure 9 on the side initially gathers the red dates on the ground, and then the red dates are sucked into the picking suction port 11, and transported to the cleaning box 31 of the cleaning device 3 through the conveying hose 12. Due to their own heavy weight, the red dates are blocked by the date blocking plate 33 and fall into the air lock 35 on the rear side. The air lock 35 rotates and discharges them from the cleaning box 31. They are transported by the grid conveying device 4 to the collection container placed on the date collecting platform 7 on the rear side of the fuselage. The impurities carried by the airflow are lighter and will be discharged to the front air lock 35 by the counterclockwise rotation of the drum screen 32, and discharged to the bottom of the fuselage under its steering.
