Description

Technical Field

[0001] This utility model relates to the technical field of Astragalus harvesting device for excavators, and in particular to an Astragalus harvesting device that prevents root breakage. Background Technology

[0002] Astragalus, also known as Huangqi, is the root of the legume Astragalus membranaceus or Astragalus mongholicus. It is one of the most representative qi-tonifying herbs in traditional Chinese medicine, known for its immune-boosting and edema-reducing effects. Astragalus is a deep-rooted plant, extremely fond of sunlight and cold-hardy but intolerant of waterlogging. It thrives in deep, loose, well-drained, neutral or slightly alkaline sandy soils and is distributed throughout northern China. Its medicinal taproot can grow vertically downwards to 1 meter or even 2 meters or more, making it prone to breakage during harvesting. The quality of astragalus largely depends on the integrity of its roots. A robust, intact, unbranched root ("whip-shaped astragalus") is far more valuable than a broken root. Therefore, avoiding root damage during harvesting is crucial for improving the quality of astragalus. Traditional manual harvesting methods are not only inefficient but also prone to root breakage due to improper handling.

[0003] Existing mechanical harvesting equipment typically uses excavators, replacing the excavator's actuator with a toothed fork. During harvesting, the toothed fork is inserted into the soil and turns it up in chunks. The toothed structure ensures efficient soil turning while avoiding damage to the rhizomes. However, after turning up the soil containing the astragalus rhizomes, this type of harvesting mechanism still requires manual labor or a vibrating screen to separate the soil from the rhizomes, making the harvesting process cumbersome. Utility Model Content

[0004] This invention addresses the problem that existing Astragalus harvesting mechanisms require manual or vibrating screen separation of the soil and Astragalus roots after turning over the soil containing the Astragalus roots, resulting in a cumbersome harvesting process. Therefore, this invention provides an Astragalus harvesting device that prevents root breakage, thus solving the problems mentioned in the background art.

[0005] The technical solution of this utility model is:

[0006] A harvesting device for Astragalus membranaceus that prevents root breakage includes a first crossbar, a fixing part, a first digging tooth, a retractable second digging tooth, and a vibration mechanism.

[0007] The sidewall of the first crossbar is provided with a plurality of first digging teeth arranged in an axial array. A fixing part is provided on the first crossbar. A first ear plate is provided on the first crossbar. A retractable second digging tooth is hinged on the first ear plate. A vibration mechanism for driving the retractable second digging tooth to vibrate is provided on the fixing part.

[0008] Furthermore, the retractable second digging tooth includes a slide rail, a slider, a second crossbar, a second digging tooth, and a telescopic drive mechanism;

[0009] The slide rail is hinged to the first ear plate, and a slider is slidably connected to the slide rail. A telescopic drive mechanism for pushing the slider to slide along the slide rail is installed on the slide rail. A second crossbar is fixedly connected to the slider, and multiple second digging teeth are arranged in an axial array on the side wall of the second crossbar.

[0010] Furthermore, the first and second digging teeth are alternately arranged.

[0011] Furthermore, the telescopic drive mechanism is a hydraulic push rod.

[0012] Furthermore, the telescopic drive mechanism is a DC electric actuator.

[0013] Furthermore, the vibration mechanism adopts a rocker arm mechanism, with the fixed end of the rocker arm mechanism fixedly connected to the fixed part, and the output end of the rocker arm mechanism hinged to the slide rail.

[0014] Furthermore, the rocker arm mechanism includes a drive unit, an eccentric wheel, and a push rod;

[0015] The drive unit is installed on the upper end of the fixed part. The output shaft of the drive unit is equipped with an eccentric wheel, and a push rod is hinged on the eccentric wheel. The push rod is hinged to the slide rail.

[0016] Furthermore, the drive unit uses a hydraulic motor.

[0017] Furthermore, the drive unit uses a DC motor.

[0018] Furthermore, a set of parallel second ear plates are provided on the fixing part.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1. A harvesting device for Astragalus membranaceus that prevents root breakage, comprising a first digging tooth and a second digging tooth in a V-shape. The second digging tooth can extend and retract via a slide rail and a slider to grip the soil from the bottom. During operation, the excavator inserts the first digging tooth into the soil. At this time, the extension drive mechanism is activated, pushing the slider along the slide rail, thereby driving the second digging tooth to insert into the soil until the ends of the first and second digging teeth contact each other. The first and second digging teeth form a V-shaped structure, creating a gripping effect on the soil. The second digging tooth achieves the gripping action by sliding into the soil. Compared with an opening and closing gripper mechanism, this avoids squeezing the soil, effectively reducing the compression and breakage of Astragalus membranaceus caused by soil deformation, and minimizing root breakage.

[0021] 2. The first and second digging teeth are hinged and equipped with a vibration mechanism to enable the second digging tooth to open and close relative to the first digging tooth at a high frequency, thereby patting and vibrating the soil and causing the soil on the Astragalus rootstock to fall off. The vibration mechanism includes a hydraulic motor, which drives an eccentric wheel to rotate. The eccentric wheel drives a push rod to swing the rocker arm mechanism. The push rod pushes the slide rail to swing, causing the second digging tooth to vibrate at a high frequency under the drive of the slide rail, forming an opening and closing patting action with the first digging tooth. Through the operation of the vibration mechanism, the soil is vibrated and falls off more quickly, solving the problem in the existing technology where, after turning out the soil carrying the Astragalus rootstock, it is still necessary to manually separate the soil from the Astragalus rootstock using a vibrating screen, resulting in a cumbersome harvesting process.

Detailed Implementation

[0029] Specific implementation method one: See Figure 1-6 As shown, an Astragalus harvesting device to prevent root breakage is provided in this embodiment, which includes a first crossbar 101, a fixing part 102, a first digging tooth 103, a retractable second digging tooth, and a vibration mechanism.

[0030] The sidewall of the first crossbar 101 is provided with a plurality of first digging teeth 103 arranged in an axial array. The first crossbar 101 is provided with a fixing part 102 and a first ear plate 104. A retractable second digging tooth is hinged to the first ear plate 104. The fixing part 102 is provided with a vibration mechanism for driving the retractable second digging tooth to vibrate.

[0031] Furthermore, the first crossbar 101 provides support and linkage. Multiple first digging teeth 103 are welded to the side wall of the first crossbar 101. The first digging teeth 103 are perpendicular to the axis of the first crossbar 101, and each first digging tooth 103 is evenly spaced to ensure uniform force distribution during digging. The lower end of the first digging tooth 103 is provided with a tapered tip, which facilitates insertion into the soil, reduces resistance, and avoids the rhizome of Astragalus membranaceus, preventing damage to the rhizome. The fixing part 102 is fixedly connected to the first crossbar 101 by welding, and the fixing part 102 is set perpendicular to the first digging teeth 103. The fixing part 102 serves as a connection, used to connect with the execution end of the excavator. The retractable second digging tooth slides and forms a V-shaped structure with the first digging tooth 103 to grasp the soil. The vibration mechanism drives the retractable second digging tooth to open and close relative to the first digging tooth 103 at a high frequency, which beats and vibrates the soil, causing the soil on the Astragalus membranaceus rhizome to fall off.

[0032] Specific Implementation Method Two: See Figure 3-4 As shown, the retractable second digging tooth of this embodiment includes a slide rail 201, a slider 202, a second crossbar 203, a second digging tooth 204, and a telescopic drive mechanism 205.

[0033] The slide rail 201 is hinged to the first ear plate 104. A slider 202 is slidably connected to the slide rail 201. A telescopic drive mechanism 205 for pushing the slider 202 to slide along the slide rail 201 is installed on the slide rail 201. A second crossbar 203 is fixedly connected to the slider 202. Multiple second digging teeth 204 are arranged in an axial array on the side wall of the second crossbar 203.

[0034] Furthermore, the first ear plate 104 is welded to the first crossbar 101. The first ear plate 104 has a hinge hole, and the lower end of the slide rail 201 has a rotating shaft connected to the hinge hole, allowing the slide rail 201 to rotate around the first ear plate 104. The slide rail 201 is composed of a square frame, with two vertical cylindrical slide rails arranged parallel to each other on the two vertical sides of the square frame. The slider 202 is rectangular, with a circular groove matching the cylindrical slide rail. The slider 202 slides up and down by engaging with the cylindrical slide rail through the circular groove. The fixed end of the telescopic drive mechanism 205 is fixed to the upper end of the square frame of the slide rail 201, and the movable end of the telescopic drive mechanism 205 is fixedly connected to the upper surface of the slider 202. The slider 202 is welded to the second crossbar 203. The arrangement of the second crossbar 203 and the second digging tooth 204 is the same as the arrangement of the first digging tooth 103 and the first crossbar 101.

[0035] Working principle: When the excavator inserts the first digging tooth 103 into the soil, the telescopic drive mechanism 205 is activated. The telescopic drive mechanism 205 extends, pushing the slider 202 along the slide rail 201, thereby causing the second digging tooth 204 to insert into the soil until the ends of the first digging tooth 103 and the second digging tooth 204 contact each other. The first digging tooth 103 and the second digging tooth 204 form a V-shaped structure, creating a gripping effect on the soil. The excavator then lifts the first digging tooth 103 and the second digging tooth 204, removing the astragalus root and soil together from the soil. The second digging tooth 204 achieves the gripping action by sliding into the soil. Compared to an opening and closing gripper mechanism, this avoids squeezing the soil, effectively reducing soil deformation and the risk of astragalus root breakage, minimizing root damage.

[0036] Specific implementation method three: See Figure 1 As shown, in this embodiment, the first digging tooth 103 and the second digging tooth 204 are alternately arranged.

[0037] Furthermore, by arranging the first digging tooth 103 and the second digging tooth 204 alternately, the second digging tooth 204 slides downward along the slide rail 201 and crosses at the lower end of the first digging tooth 103 to form a V-shape, the first digging tooth 103 and the second digging tooth 204 do not interfere with each other when they cross.

[0038] Detailed Implementation Method Four: See [link] Figure 3-4 As shown, the telescopic drive mechanism 205 in this embodiment is a hydraulic push rod.

[0039] Furthermore, if the excavator uses a hydraulic system as its power source, the telescopic drive mechanism 205 is preferably a hydraulic cylinder.

[0040] Specific implementation method five: See Figure 3-4 As shown, the telescopic drive mechanism 205 in this embodiment is a DC electric push rod.

[0041] Furthermore, if the excavator uses a DC electric system as its power source, the telescopic drive mechanism 205 is preferably an electric push rod.

[0042] Specific implementation method six: See Figure 5-6 As shown, the vibration mechanism in this embodiment adopts a rocker arm mechanism. The fixed end of the rocker arm mechanism is fixedly connected to the fixed part 102, and the output end of the rocker arm mechanism is hinged to the slide rail 201.

[0043] Furthermore, the first digging tooth 103 and the second digging tooth 204 are connected by a rocker arm mechanism to achieve high-frequency opening and closing of the second digging tooth 204 relative to the first digging tooth 103, thereby patting and vibrating the soil.

[0044] Detailed implementation method seven: See Figure 5-6As shown, the rocker arm mechanism of this embodiment includes a drive device 301, an eccentric wheel 302, and a push rod 303.

[0045] The drive unit 301 is installed on the upper end of the fixed part 102. The output shaft of the drive unit 301 is provided with an eccentric wheel 302. A push rod 303 is hinged on the eccentric wheel 302 and is hinged to the slide rail 201.

[0046] Furthermore, the drive device 301 is fixed to the upper end of the fixing part 102 by bolts, and a rotating shaft is provided on the slide rail 201. The push rod 303 is hinged to the rotating shaft on the slide rail 201.

[0047] Working principle: When the drive device 301 is started, the eccentric wheel 302 rotates with the output shaft. The push rod 303 reciprocates under the action of the eccentric wheel 302. The push rod 303 drives the slide rail 201 to swing around the axis, thereby causing the second digging tooth 204 to oscillate at high frequency relative to the first digging tooth 103. This patting and vibration of the soil between the first digging tooth 103 and the second digging tooth 204 separates the soil from the Astragalus root. Under the action of gravity, the soil falls naturally from the gap between the first digging tooth 103 and the second digging tooth 204, completing the separation of the soil from the Astragalus.

[0048] Detailed Implementation Method Eight: See also Figure 5-6 As shown, the drive device 301 in this embodiment uses a hydraulic motor.

[0049] Furthermore, if the excavator uses a hydraulic system as its power source, the drive unit 301 is preferably a hydraulic motor.

[0050] Detailed Implementation Method Nine: See also Figure 5-6 As shown, the drive device 301 in this embodiment uses a DC motor.

[0051] Furthermore, if the excavator uses a DC electric system as its power source, the drive unit 301 is preferably a DC motor.

[0052] Detailed Implementation Method Ten: See [link / details] Figure 1 As shown, a set of parallel second ear plates 4 are provided on the fixing part 102 of this embodiment.

[0053] Furthermore, the second ear plate 4 has two shaft holes for connecting to the actuator end of the excavator.

[0054] During operation, the excavator inserts the first digging tooth 103 into the soil. The telescopic drive mechanism 205 extends, causing the second digging tooth 204 to also insert into the soil. The excavator then lifts the first digging tooth 103 and the second digging tooth 204, removing the astragalus root and soil together from the soil. The drive unit 301 is activated, and the eccentric wheel 302 rotates with the output shaft of the drive unit 301. This rotation, via the push rod 303, causes the second digging tooth 204 to oscillate at a high frequency relative to the first digging tooth 103, thus separating the astragalus root from the soil.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
