Description

Technical Field

[0001] This invention relates to a vertical lifting device and a collecting device for a Panax notoginseng combine harvester, belonging to the field of agricultural machinery and equipment. Background Technology

[0002] Panax notoginseng is a famous traditional Chinese medicine containing various physiologically active substances such as flavonoids, polysaccharides, and amino acids. It is especially rich in over 50 monomeric saponins, giving it high medicinal value and the ability to dispel blood stasis, promote blood circulation, reduce swelling and pain, fight tumors, and slow aging. For a long time, Panax notoginseng harvesting has been done manually, resulting in high costs, high labor intensity, and low efficiency, which has greatly hindered the industry's development. Currently, the only equipment available for harvesting Panax notoginseng is a simple segmented harvesting excavator equipped with a digging device and a rod-type conveying and separating device. This can only complete the digging and partial root-soil separation of Panax notoginseng; subsequent manual collection and bagging are still required. This is far from comprehensive harvesting, and the mechanized harvesting of Panax notoginseng urgently needs to be solved. For comprehensive harvesting, the key lies in how to efficiently collect and unload the Panax notoginseng tubers transported by the front-end digging and conveying / separating devices, solving problems such as entanglement and damage during transport, and the inability to effectively fill the hopper due to the large angle of repose of Panax notoginseng. Summary of the Invention

[0042] Example 2: This example is the same as the previous example in other parts, wherein the driving sprocket (415) and the driven sprocket (413) are of the same specifications and are located on the same horizontal line to ensure that the support roller I (421) and the support roller II (419) move at the same speed.

[0043] Example 3: This example is the same as the previous example in other parts, except that the roller shaft (11a) is equipped with a DC motor, which can make the roller shaft (11a) rotate in both directions.

[0044] Example 4: This example is the same as the previous example in other parts. The DC geared motor (15), DC motor (13) and roller shaft (11a) are all controlled by the program to rotate. The roller shaft (11a) of the flexible spiral roller (11) has a rubber spiral groove (11b). When the roller shaft (11a) rotates, the axial movement of the three-seven block root can be realized.

[0046] Example 6: This example is the same as the previous example in other parts, except that the width of the conveyor belt (411) is 500mm and the width of the grid (49) is 460mm, the difference between which is twice the width of guide wheel I (416) and guide wheel II (418) of 20mm. The working principle of this invention is:

[0047] The Panax notoginseng rootlets with low impurity content, obtained by the digging device and the conveying and separating devices at each stage of the Panax notoginseng combine harvester, are thrown onto the conveyor belt (411). Through the action of the power transmission system I, the conveyor belt (411) and the grid (49) move synchronously until the Panax notoginseng rootlets are transported into the hopper (22). Due to the fixed position of the discharge port and the large natural angle of repose of Panax notoginseng, the Panax notoginseng will only accumulate on one side and cannot fill the complete volume of the hopper (22). When the sensor detects this phenomenon, it will activate... The rotating anti-winding and spreading device (1) controls the movement of the DC geared motor (15), DC motor (13) and roller shaft (11a) to make Panax notoginseng move in the horizontal and vertical directions, so that Panax notoginseng can fill the entire hopper (22). When Panax notoginseng needs to be unloaded, the rotating anti-winding and spreading device (1) will retract, and at the same time, the outer plate (410) of the discharge port will be flipped under the action of the flipping hydraulic cylinder (46). Finally, under the action of the hydraulic cylinder (23), the hopper (22) will be raised to complete the unloading of Panax notoginseng.

[0048] The specific embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
