Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a harvesting device for planting Polygonatum yunnanense. Background Technology

[0002] Yunnan Polygonatum is a plant used for both food and medicine, and is also one of the source plants of the medicinal herb Polygonatum. Its dried rhizome is sweet and neutral in nature, and enters the spleen, lung, and kidney meridians. It can replenish qi and nourish yin, strengthen the spleen, moisten the lungs, and benefit the kidneys. When Yunnan Polygonatum is harvested, most areas still use the traditional method of digging it out of the soil with tools such as shovels and hoes and then collecting it. This method is not only inefficient, but also prone to shallow digging and damage to the Yunnan Polygonatum due to human fatigue, resulting in some Yunnan Polygonatum being missed. Especially during the peak harvesting period of Yunnan Polygonatum, if the harvesting speed is too slow, the Yunnan Polygonatum will become over-ripened and aged, thus reducing its quality. Utility Model Content

[0003] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: a harvesting device for planting Polygonatum yunnanense, comprising: a frame, a screening device disposed inside the frame, a soil-crushing device rotatably connected to the inner wall of the frame, a plow blade fixedly connected to the inner wall of the frame, and a movable wheel rotatably connected to the outer wall of the frame; the screening device includes a motor, a pulley assembly disposed at the output end of the motor, eccentric wheels symmetrically disposed outside the pulley assembly, a connecting rod slidably connected to the inner wall of the eccentric wheel, a connecting rod rotatably connected to the outer wall of the connecting rod, a connecting foot rotatably connected to the end of the connecting rod away from the connecting rod, a sieve plate fixedly connected to the outer wall of the connecting foot, and the eccentric wheel, through a groove disposed thereon, allows the connecting rod to slide within the groove, thereby adjusting the eccentricity of the connecting rod, affecting the swing amplitude of the connecting rod, further changing the swing amplitude of the connecting foot and the sieve plate, and thus changing the swing frequency of the sieve plate.

[0004] Preferably, the outer wall of the motor is fixedly connected to the top of the frame, the outer wall of the eccentric wheel is rotatably connected to the top of the frame, the eccentric wheel is driven by the output end of the motor through a pulley set, the outer wall of the sieve plate is rotatably connected to the inner wall of the frame, and the top of the frame provides support for the entire screening device.

[0005] Preferably, the outer wall of the connecting rod is threaded with a fastening nut, and the inner wall of the fastening nut is threaded with an anti-slip bolt. The outer wall of the fastening nut is slidably connected to the outer wall of the eccentric wheel, and the outer wall of the anti-slip bolt is slidably connected to the inner wall of the connecting rod. The fastening nut achieves its fastening purpose by tightening towards the eccentric wheel and pressing the eccentric wheel with the connecting rod. The anti-slip bolt, by tightening and moving downwards, is simultaneously inside the connecting rod and the fastening nut, thereby preventing the fastening nut from slipping.

[0006] Preferably, the soil shredding device includes a soil shredding roller, and a differential wheel is provided on the outside of the soil shredding roller. The soil shredding roller and the differential wheel are connected by a transmission belt. A transmission protective shell is provided on the outside of the differential wheel. The transmission protective shell provides physical protection so that the entire differential structure does not enter the soil, thus playing a protective role.

[0007] Preferably, the soil-crushing roller is rotatably connected to the inner wall of the frame, the differential wheel is rotatably connected to the inner wall of the frame, the transmission protective shell is fixedly connected to the inner wall of the frame, the differential wheel is connected to the moving wheel via a transmission belt, and the differential wheel is connected to the small wheel of the moving wheel and the large wheel of the soil-crushing roller via the transmission belt, so as to amplify the rotational speed transmitted by the moving wheel to the soil-crushing roller.

[0008] The beneficial effects of this utility model are as follows: 1. This utility model comprises a motor, a pulley assembly, rollers, a connecting rod, a connecting rod, a connecting foot, and a sieve plate. During operation, the two output ports of the motor transmit power to the rollers through the pulley assembly. The connecting rod then rotates eccentrically on the rollers, causing the connecting rod to oscillate back and forth. Simultaneously, this oscillates the connecting foot and the sieve plate. The sieve plate, through its oscillation, separates the soil from the Solomon's seal and throws the Solomon's seal backward, thus achieving the purpose of separating and transporting the Solomon's seal.

[0009] 2. This utility model is equipped with a soil-crushing roller, a belt, a differential wheel, and a moving wheel. The small wheel of the differential wheel is connected to the moving wheel via a belt, and the large wheel of the differential wheel is connected to the soil-crushing roller via a belt. When working, the moving wheel rotates, which drives the differential wheel to rotate, and the small wheel drives the large wheel, so that the soil-crushing roller can obtain a faster rotation speed. It can not only crush large pieces of soil, but also scoop the material into the device and into the screening device for separation. Attached Figure Description

The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0012] Example: Please see Figure 1 - Figure 5 This utility model provides a technical solution: a harvesting device for the cultivation of Polygonatum yunnanense.

[0013] The frame 1 has a screening device 2 inside, a soil crushing device 5 rotatably connected to the inner wall of the frame 1, a plow blade 3 fixedly connected to the inner wall of the frame 1, and a moving wheel 4 rotatably connected to the outer wall of the frame 1. The screening device 2 includes a motor 21, a pulley group 22 is provided at the output end of the motor 21, an eccentric wheel 23 is symmetrically arranged on the outside of the pulley group 22, a connecting rod 24 is slidably connected to the inner wall of the eccentric wheel 23, a connecting rod 25 is rotatably connected to the outer wall of the connecting rod 24, a connecting foot 28 is rotatably connected to the end of the connecting rod 25 away from the connecting rod 24, and a screening plate 29 is fixedly connected to the outer wall of the connecting foot 28.

[0014] The outer wall of the eccentric wheel 23 is rotatably connected to the top of the frame 1. The eccentric wheel 23 is connected to the output end of the motor 21 via the pulley group 22. The outer wall of the sieve plate 29 is rotatably connected to the inner wall of the frame 1.

[0015] The outer wall of the connecting rod 24 is threaded with a fastening nut 26, and the inner wall of the fastening nut 26 is threaded with an anti-slip bolt 27. The outer wall of the fastening nut 26 is slidably connected to the outer wall of the eccentric wheel 23, and the outer wall of the anti-slip bolt 27 is slidably connected to the inner wall of the connecting rod 24.

[0016] The soil breaking device 5 includes a soil breaking roller 51, and a differential wheel 52 is provided on the outside of the soil breaking roller 51. The soil breaking roller 51 and the differential wheel 52 are connected by a transmission belt 54. A transmission protective shell 53 is provided on the outside of the differential wheel 52.

[0017] The soil-breaking roller 51 is rotatably connected to the inner wall of the frame 1, the differential wheel 52 is rotatably connected to the inner wall of the frame 1, the transmission protective shell 53 is fixedly connected to the inner wall of the frame 1, and the differential wheel 52 is connected to the moving wheel 4 through the transmission belt 54.

[0018] Working principle: In use, the tractor connects to the frame 1, allowing the device to be driven and raised / lowered. When the tractor, carrying the device, reaches the harvesting site of *Polygonatum yunnanensis*, it lowers the device until the plow blade 3 penetrates the soil. Then, the anti-slip bolt 27 is unscrewed, and the fastening nut 26 is loosened. By adjusting the position of the connecting rod 24 on the inner wall of the eccentric wheel 23, the eccentricity of the connecting rod 24 is changed, thereby altering the reciprocating swing frequency of the connecting rod 25. This changes the swing frequency of the connecting foot 28 and the sieve plate 29, achieving the desired swing frequency adjustment for the current soil conditions. After adjustment, the fastening nut 26 is rotated to press the connecting rod 24, locking its position. The anti-slip bolt 27 is then screwed in, simultaneously engaging the fastening nut 26 and the inner wall of the connecting rod 24 to prevent slippage. As the tractor moves, the plow blade 3 breaks through the soil, feeding material into the device. Simultaneously, the moving wheel 4 begins to rotate, interacting with the moving wheel... The transmission belt 54 of the transmission connection causes the differential wheel 52 to rotate, and the small wheel drives the large wheel, increasing the transmission speed. Then, the transmission belt 54, which is connected to the differential wheel 52 and the soil crushing roller 51, transmits the speed to the soil crushing roller 51, causing the soil crushing roller 51 to rotate and crush the large clods of soil fed in by the plow blade 3. At the same time, it pulls the material inward. Then, by setting a transmission protection shell 53 outside the differential wheel 52, the entire differential structure is physically protected to prevent the soil from being turned up into the entire belt transmission device. At the same time, the motor 21 provides power. The motor 21 is connected to the pulley group 22 through the output ports at both ends, causing the pulley group 22 to drive the eccentric wheel 23 to rotate. Then, the restricted connecting rod 24 rotates eccentrically, causing the connecting rod 25 to swing back and forth. At the same time, it drives the connecting foot 28 and the sieve plate 29 to swing back and forth. Through the swing, the soil and the Solomon's seal are separated, and the Solomon's seal is slowly thrown backward away from the sieve plate 29.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, are implemented according to conventional means in the art.
