Description
Technical Field
[0001] This utility model belongs to the field of agricultural harvesting technology, specifically relating to an Astragalus membranaceus digging device. Background Technology
[0002] Astragalus is an important traditional Chinese medicine, with its main medicinal part being the root. As a deep-rooted plant, the taproot is thick and can penetrate tens of centimeters into the soil. This is a key characteristic that allows it to absorb nutrients from deep soil layers and is drought-resistant, but it also makes harvesting this type of crop difficult.
[0003] During harvesting, workers need to use shovels or hoes to dig several tens of centimeters deep at a certain distance from the plant before removing the entire Astragalus root from the soil. This process presents several problems: digging up Astragalus roots one by one requires a lot of time and physical labor, resulting in high labor intensity and harvesting costs, which affects the profitability of large-scale Astragalus cultivation. Utility Model Content
[0004] This application proposes an Astragalus membranaceus digging device, which can realize the batch digging of Astragalus membranaceus, thereby improving the harvesting efficiency of Astragalus membranaceus.

A third motor is installed at the other end of at least one rotating arm, and the output end of the third motor is drivenly connected to the rotating shaft. Multiple forks are connected to the inner side of the bucket. An inclined grid plate is provided inside the material cavity, and baffles are spaced apart at the lower end of the grid plate.
[0006] In one embodiment of this application, the fork has a pointed tip at its front end.
[0007] In one embodiment of this application, a sieve plate is provided below the grid plate.
[0008] In one embodiment of this application, a vibrator is provided at the lower part of the sieve plate.
[0009] In one embodiment of this application, the inner wall of the bucket is provided with a plurality of insertion holes for inserting forks.
[0010] In one embodiment of this application, a counterweight is provided at the upper end of the base plate.
[0011] In one embodiment of this application, the upper part of the material cavity is provided with an outwardly expanding edge.

[0020] This embodiment provides an Astragalus membranaceus excavation device, see reference. Figures 1-6 As shown, the device includes a base plate 1, with wheels 2 on the side of the base plate 1. A material cavity 3 is located on the upper part of the base plate 1. Rotary arms 31 are respectively located on both sides of the material cavity 3. One end of each rotary arm 31 is rotatably connected to the side of the material cavity 3. At least one rotary arm 31 is drivenly connected to the output end of a second motor 311. The body of the second motor 311 is fixedly connected to the side wall of the material cavity 3 through a fixing frame. The other ends of the two rotary arms 31 are respectively rotatably connected to the two ends of a rotating shaft 4. The outer wall of the rotating shaft 4 is fixedly connected to a bucket 5. A third motor 312 is installed on the other end of at least one rotary arm 31, and the output end of the third motor 312 is drivenly connected to the rotating shaft 4. Multiple forks 51 are connected to the inner side of the bucket 5. An inclined grid plate 32 is provided inside the material cavity 3. Baffles 33 are spaced apart at the lower end of the grid plate 32.
[0021] In the above embodiment, a traveling wheel 2 is provided on the side of the base plate 1, and a first motor 100 is installed on the bottom surface of the base plate 1. The output end of the first motor 100 is connected to the traveling wheel 2 for transmission. The traveling wheel 2 is used to lift the base plate 1 off the ground and drive the base plate 1 to move on the ground. A material cavity 3 is provided on the upper part of the base plate 1. Rotating arms 31 are respectively provided on both sides of the material cavity 3. One end of the rotating arm 31 is rotatably connected to the side of the material cavity 3. At least one rotating arm 31 is connected to the output end of a second motor 311 for transmission. The body of the second motor 311 is fixedly connected to the side wall of the material cavity 3 through a fixing frame. The other ends of the two rotating arms 31 are respectively rotated with the two ends of the rotating shaft 4. The outer wall of the rotating shaft 4 is fixedly connected to the bucket 5. At least one rotating arm 31 has a third motor 312 installed at the other end, and the output end of the third motor 312 is connected to the rotating shaft 4 for transmission. Multiple forks 51 are connected to the inner side of the bucket 5. During use, the third motor 312 drives the rotating shaft 4 to rotate, which in turn drives the forks 51 of the bucket 5 to deflect towards the ground. The bucket 5 is not a traditional plate structure. The traveling wheel 2 drives the material cavity 3 on the bottom plate 1, which in turn drives the rotating arm 31 to move forward, so that the multiple forks 51 are inserted obliquely into the soil. There are gaps between the forks 51 to avoid cutting off the roots of Astragalus membranaceus when the bucket 5 is inserted into the soil. That is, the traveling wheel 2 drives the device forward, so that the forks 51 are inserted into the soil obliquely like a "comb". The gaps between the forks 51 ensure that the main root of Astragalus membranaceus can be accommodated in the gaps during the insertion process, rather than being forcibly cut off, thereby achieving protective excavation, reducing the root breakage rate, and improving the quality of Astragalus membranaceus. After the fork 51 is inserted into the soil to a certain depth, the third motor 312 drives the rotating shaft 4, which in turn drives the bucket 5 to deflect away from the ground. The fork 51 digs out the soil clods wrapped around the roots of Astragalus membranaceus in the soil and collects them in the bucket 5. At this time, the second motor 311 drives the rotating arm 31, which in turn drives the bucket 5 to deflect upwards in the material cavity 3, so that the Astragalus membranaceus roots wrapped with soil fall into the material cavity 3. The material cavity 3 is equipped with an inclined grid plate 32. The lower part of the grid plate 32... At the end, spaced baffles 33 are installed. As the Astragalus root clumps of soil fall, they collide with and break against the grid plates 32, separating the Astragalus root from the soil. The broken soil clumps slide down the inclined grid plates 32 and flow out of the material chamber 3 through the gaps between the baffles 33. Some of the broken soil falls back to the ground through the opening at the bottom of the material chamber 3 via the gaps in the grid plates 32. The long, strip-shaped Astragalus root remains inside the material chamber 3, thus achieving separation of the Astragalus root from the soil. In summary, compared to manual digging with a shovel, using the bucket 5 improves the digging efficiency of Astragalus roots. Furthermore, the collision and breakage of the soil clumps carried by the Astragalus root with the grid plates 32 during its fall, separating the Astragalus root from the soil, is beneficial for improving the efficiency of Astragalus harvesting.
[0022] In one embodiment of this application, see [reference] Figure 6 As shown, the front end of the fork 51 is provided with a pointed tip.
[0023] In the above embodiment, the pointed tip at the front end of the fork 51 is provided to reduce the resistance when the fork 51 enters the soil. When the flat-headed fork 51 is inserted, it will push the soil forward, which may cause compression or even damage to the Astragalus root system located in front of the fork 51. The pointed tip design can separate the soil and the root system, guide the root system into the gap of the fork 51, and play a further protective role.
[0024] In one embodiment of this application, see [reference] Figure 5 As shown, a sieve plate 321 is provided below the grid plate 32.
[0025] In the above embodiments, some fibrous roots, lateral roots, or poorly grown small Astragalus membranaceus main roots may leak out through the holes of the grid plate 32. The aperture of the sieve plate 321 is smaller than that of the grid plate 32 to intercept these small roots and stems, thereby reducing the leakage rate and loss rate of Astragalus membranaceus and improving the economic benefits of harvesting.
[0026] In one embodiment of this application, see [reference] Figure 5 As shown, a vibrator 322 is provided at the lower part of the sieve plate 321.
[0027] In the above embodiment, the vibrator 322 drives the sieve plate 321 to vibrate, causing the Astragalus roots on the sieve plate 321 to bounce and roll, making their separation from the attached soil more thorough and rapid. In addition, the sieve vibration can prevent soil from clogging the sieve holes, keep the sieve holes unobstructed, and ensure that the screening process is continuous and efficient.
[0028] In one embodiment of this application, see [reference] Figure 6 As shown, the inner wall of the bucket 5 is provided with a plurality of insertion holes 52, which are used to insert the fork rod 51.
[0029] In the above embodiment, the inner wall of the bucket 5 has a plurality of evenly arranged insertion holes 52 for inserting the forks 51. By inserting the forks 51 into the insertion holes 52 at different positions, the spacing between the forks 51 can be adjusted to accommodate the harvesting of Astragalus membranaceus of different diameters, which is beneficial to improving the adaptability of the device for harvesting. The gap width can be quickly changed by simply pulling out the forks 51 and inserting them into the insertion holes 52 at different positions. When harvesting one-year-old fine roots, the gap is adjusted to be smaller, for example, 25 mm, and when harvesting three-year-old coarse roots, the gap is adjusted to be larger, for example, 40 mm.
[0030] In one embodiment of this application, see [reference] Figure 4 As shown, a counterweight 6 is provided on the upper end of the base plate 1.
[0031] In the above embodiment, the counterweight 6 set on the upper end of the base plate 1 is used to lower the center of gravity of the device, increase stability, avoid the risk of tipping over during operation, and improve operational safety.
[0032] In one embodiment of this application, see [reference] Figure 5 As shown, the upper part of the material cavity 3 is provided with an outwardly expanding edge 7.
[0033] In the above embodiment, the upper part of the material cavity 3 is provided with an outwardly expanding edge 7 to increase the opening of the material cavity 3. When the bucket 5 dumps the astragalus soil, the inclined outwardly expanding edge 7 can guide the falling material, making it slide more smoothly towards the grid plate 32 area in the center of the material cavity 3.
[0034] In actual use of this application: the base plate 1 is made of Q235 steel plate by cutting and welding, the walking wheels 2 are four rubber inflatable wheels, and the first motor 100 is a DC brushless servo motor equipped with a reducer to increase torque and provide stable and controllable walking power for the device.
[0035] The boom 31 is made of square steel tubing. The second motor 311 and the third motor 312 can be DC brushless servo motors, which have high torque and fast response characteristics to ensure the control of the lifting and rotation of the bucket 5. The bucket 5 is made of stainless steel. The fork 51 is made of 45# round steel with a diameter of 12mm and surface hardening treatment to enhance wear resistance. For example, the spacing between adjacent forks 51 is set to 30~40mm to accommodate the main root diameter of most 2-3 year old Astragalus membranaceus.
[0036] During the excavation process, the operator can use a PLC or microcontroller to send control commands to the motors. The third motor 312 drives the fork 51 of the bucket 5, for example, to insert it into the soil at a 45-degree angle. The depth is controlled by the motor's rotation angle and operated according to the actual situation. After the traveling wheels 2 drive the device forward, the fork 51 inserts into the soil, the third motor 312 reverses, and the bucket 5 flips upward to dig up the soil. Then, the second motor 311 starts, lifting the boom 31 and the bucket 5 onto the material chamber 3 to pour the material into the material chamber 3. After the soil clods collide and are screened by the grid plate 32, the astragalus is collected, and the soil falls back into the field.
