Description

A soil and rhizome separation device for harvesting Angelica sinensis Technical Field

[0001] This utility model relates to the field of Angelica sinensis harvesting technology, specifically to a soil and rhizome separation device for Angelica sinensis harvesting. Background Technology

[0002] Angelica sinensis (scientific name: Angelica sinensis), belonging to the genus Angelica in the family Apiaceae, is a perennial deep-rooted herb. The medicinal part is its fleshy root, which is multi-branched. Angelica sinensis is a medicinal and edible herb with high market demand. It is now cultivated on a large scale, and harvesting is mostly done in October and November, primarily using mechanical harvesting methods.

[0003] Publication No. CN 218998872 U discloses a vibrating angelica harvester, belonging to the field of agricultural production equipment technology. The vibrating angelica harvester includes a frame, a mounting frame, wheels, a drive mechanism, a screening mechanism, and harvesting components. The frame is mounted on the rear of a tractor via the mounting frame, and the harvesting components for harvesting angelica are installed on the frame. The harvesting components are adjustable. The frame also has a screening mechanism for separating angelica from soil, and the screening mechanism is connected to the drive mechanism, which enables the screening mechanism to vibrate linearly. The frame is also equipped with wheels for easy movement. In use, the adjustable harvesting components prevent the angelica from being broken during harvesting, ensuring the quality of the harvested angelica. The drive mechanism causes the screening mechanism to vibrate linearly, separating the harvested angelica from the soil, facilitating subsequent unified collection of the angelica and improving harvesting efficiency.

[0004] The aforementioned technical solution involves digging Angelica sinensis out of the ground using a harvesting component, and then removing the soil from the Angelica sinensis through linear vibration using a screening mechanism. Although this vibration method can remove soil, it can only remove soil from underground crops with thick main stems, such as radishes and sweet potatoes. Angelica sinensis has a large number of dense roots, which are fleshy roots that are often intertwined. This means that linear vibration can only remove the soil attached to the main stem of Angelica sinensis, and cannot shake off the soil entangled inside the root system. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a soil and rhizome separation device for harvesting Angelica sinensis, which has the advantages of removing not only large clumps of soil but also soil inside the roots of Angelica sinensis, thus solving the aforementioned technical problems.

[0007] Technical solution

[0008] To achieve the above object, the present utility model provides the following technical solutions: A soil and rhizome separation device for angelica harvesting, including a silo, an inlet is provided on the outer surface of the silo, and an outlet is provided at the front end of the bottom surface. A mud outlet is provided at the middle and rear end of the bottom surface of the silo and behind the outlet. A guide plate is connected inside the inlet. The tail end of the guide plate extends into the inside of the silo and is inserted into the front opening of a separation cylinder arranged inside the silo;

[0009] The separation cylinder is composed of two semi-circular sieve meshes combined. The upper part of the separation cylinder is a large sieve mesh and the lower part is a small sieve mesh. The two are buckled and fixedly connected relatively. A reinforcing rod is also connected inside the separation cylinder. The front end of the reinforcing rod is located at the opening of the separation cylinder and is also connected to a hoisting structure for lifting the separation cylinder upward. The rear end of the reinforcing rod passes through the separation cylinder and is rotatably connected to the inner wall of the silo. A linkage gear is fixedly connected to the center of the rear wall of the separation cylinder. The linkage gear meshes with a driving gear. The axis of the driving gear is connected to a speed reducer through a coupling. The speed reducer is driven by a servo motor.

[0010] As a preferred technical solution of the present utility model, the hoisting structure is an electric hoist. The hook part of the electric hoist is detachably connected to the front end of the reinforcing rod.

[0011] As a preferred technical solution of the present utility model, the reinforcing rod has a "rich" - shaped structure. The rod bodies on both sides of the reinforcing rod are fixedly connected to the connection parts of the large sieve mesh and the small sieve mesh.

[0012] As a preferred technical solution of the present utility model, the reinforcing rod is higher than the tail end of the guide plate, and the central rod body of the "rich" - shaped reinforcing rod is located at the inner axis of the separation cylinder.

[0013] As a preferred technical solution of the present utility model, a bearing is also connected to the front section of the reinforcing rod. The inner ring of the bearing is fixedly connected to the outer surface of the reinforcing rod, and the outer ring part is fixedly connected to a connecting rod. The rear end of the connecting rod is threadedly connected to the hook part of the electric hoist.

[0014] As a preferred technical solution of the present utility model, a baffle is connected to the tail end of the reinforcing rod. The front wall of the baffle is rotatably connected to the reinforcing rod through a rotating shaft, and the rear wall is fixedly connected to one end of a bearing seat. The other end of the bearing seat is fixedly connected to the inner wall of the silo. The speed reducer is detachably connected to the front wall of the baffle through bolts and is located directly above the reinforcing rod.

[0015] Compared with the prior art, the present utility model provides a soil and rhizome separation device for angelica harvesting, which has the following beneficial effects:

[0016] 1. After the feeding is completed in the separation cylinder, the electric hoist crane of the present utility model continues to maintain the posture of lifting the separation cylinder, ensuring that the subsequent soil separation of Codonopsis pilosula will not cause it to fall from the opening. By starting the servo motor in the reducer, the output end thereof increases the torque under the action of the reduction gears in the reducer and finally transmits it to the driving gear, causing it to start rotating. When the separation cylinder starts to rotate, the large sieve at its top moves first. When the large sieve rotates downward and the small sieve rotates upward, the Codonopsis pilosula inside starts to roll, and at the same time as its own rolling, it will relatively roll on the inner wall of the separation cylinder due to friction. The combination of the two causes the large lumps of soil attached to the Codonopsis pilosula itself to start falling. Then, the fallen large lumps of soil are filtered by the large sieve and fall to the mud outlet below for discharge. Further, by continuously rotating the driving gear to drive the separation cylinder to further rotate, the small sieve will reset to below the separation cylinder. At this time, as the Codonopsis pilosula continues to roll and turn, and at the same time collides with the "丰"-shaped guide plate, the small lumps of soil mixed in the root whiskers will be shaken off, and the small lumps of soil will be discharged by the small sieve to the mud outlet, achieving the advantages of not only removing large lumps of soil but also removing the soil in the root whiskers of Codonopsis pilosula.

[0017] 2. When the separation cylinder of the present utility model starts to rotate, the large sieve at its top moves first. When the large sieve rotates downward and the small sieve rotates upward, the Codonopsis pilosula inside starts to roll, and at the same time as its own rolling, it will relatively roll on the inner wall of the separation cylinder due to friction. The combination of the two causes the large lumps of soil attached to the Codonopsis pilosula itself to start falling. Then, the fallen large lumps of soil are filtered by the large sieve and fall to the mud outlet below for discharge. Further, by continuously rotating the driving gear to drive the separation cylinder to further rotate, the small sieve will reset to below the separation cylinder. At this time, as the Codonopsis pilosula continues to roll and turn, and at the same time collides with the "丰"-shaped guide plate, the small lumps of soil mixed in the root whiskers will be shaken off, and the small lumps of soil will be discharged by the small sieve to the mud outlet. In this way, batches of Codonopsis pilosula can complete soil separation in the same separation cylinder, achieving the advantage of higher efficiency when separating soil from a large quantity of Codonopsis pilosula.

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0025] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Please refer to Figures 1-5. A soil and rhizome separation device for harvesting Angelica sinensis includes a silo 1. The outer surface of the silo 1 is provided with an inlet 2, and the front end of the bottom is provided with an outlet 3. The rear end of the bottom surface of the silo 1 and the outlet 3 are provided with a mud outlet. The inner side of the inlet 2 is connected to a guide plate 201. The tail end of the guide plate 201 extends into the silo 1 and is inserted into the front opening of the separation cylinder 4 provided inside the silo 1.

[0028] The separation cylinder 4 is composed of two semi-circular sieves combined. The large sieve 401 is above the separation cylinder 4 and the small sieve 402 is below. The two are buckled relative to each other and fixedly connected. A reinforcing rod 5 is also connected inside the separation cylinder 4. The front end of the reinforcing rod 5 is located at the opening of the separation cylinder 4 and is also connected to a hoisting structure for lifting the separation cylinder 4 upward. The rear end of the reinforcing rod 5 passes through the separation cylinder 4 and is rotatably connected to the inner wall of the silo 1. A linkage gear 403 is fixedly connected to the axis of the rear wall of the separation cylinder 4. The linkage gear 403 meshes with the driving gear 404. The axis of the driving gear 404 is connected to the reducer 405 through a coupling. The reducer 405 is driven by a servo motor.

[0029] Further, as shown in Figure 1, a batch of freshly harvested angelica is put in from the feeding port 2. The batch of fresh angelica first contacts the guide plate 201, and under the action of the arc-shaped guide plate 201, the angelica is directly guided into the interior of the separation cylinder 4. At this time, the electric hoist 6 starts to lift the front part of the separation cylinder 4. Due to the existence of the bearing 501 and the connecting rod 502, it is ensured that when the hook part of the electric hoist 6 lifts the connecting rod 502, it can effectively drive the front end of the reinforcing rod 5 to lift, and the lifting of the reinforcing rod 5 will lift the separation cylinder 4 together. At this time, the rear end of the reinforcing rod 5 at the front end of the separation cylinder 4 swings upward under the support of the bearing seat, so that the separation cylinder 4 will not have hard friction in structure while tilting upward. Further, when the separation cylinder 4 is tilted up, the batch of angelica will roll towards the rear end of the separation cylinder 4 under the action of gravity, thus completing the preliminary feeding work.

[0030] Further, after the separation cylinder 4 completes the feeding, the electric hoist 6 continues to keep the posture of lifting the separation cylinder 4 to ensure that the codonopsis pilosula will not fall from the opening during the subsequent soil separation. By starting the servo motor in the reducer 405, its output end increases the torque under the action of the reduction gear in the reducer 405 and finally transmits it to the driving gear 404, making it start to rotate.

[0031] Further, when the separation cylinder 4 starts to rotate, the large sieve 401 at its top moves first. When the large sieve 401 rotates downward and the small sieve 402 rotates upward, the codonopsis pilosula inside starts to roll, and while rolling on its own, it will also roll relative to the inner wall of the separation cylinder 4 due to friction. The combination of the two makes the large pieces of soil attached to the codonopsis pilosula start to fall off. Then the fallen large pieces of soil are filtered by the large sieve 401 and fall to the mud outlet below to be discharged. Further, by continuously rotating the driving gear 404 to drive the separation cylinder 4 to further rotate, its small sieve 402 will reset to below the separation cylinder 4. At this time, as the codonopsis pilosula continues to roll and turn, and at the same time accompanied by contact and collision with the "丰"-shaped guide plate 201, the small pieces of soil mixed in the root whiskers will be shaken off, and the small pieces of soil will be discharged to the mud outlet by the small sieve 4 and fall to the mud outlet below to be discharged. In this way, a batch of codonopsis pilosula can complete the soil separation in the same separation cylinder 4, which is more time-saving and labor-saving.

[0032] Example 2

[0033] Furthermore, since the reduction gear 405 is used to drive the separation cylinder 4 to continuously perform circular motion, the large screen 401 and the small screen 402 will be continuously switched, which may cause the surface of a batch of Angelica sinensis to be damaged due to intense collision. Therefore, this situation is changed by setting the output sequence of the servo motor. The servo motor used is the Mitsubishi MR-J4 series servo motor. The steering control of the servo motor is realized by adjusting specific parameters. This technical solution belongs to the prior art and is information known to the public in the market, so it will not be publicly repeated here. By setting the servo motor to rotate half a circle and reset n times and then perform a full circle rotation, the large screen 401 or the small screen 402 of the separation cylinder 4 can be in a state of swinging back and forth for a long time. In this state, the Angelica sinensis will be in a repeated arc rolling posture and will not roll violently, which can reduce the possibility of surface damage of the Angelica sinensis during soil separation.

[0034] During use, a batch of freshly harvested Angelica sinensis is put in from the feeding port 2. The batch of freshly harvested Angelica sinensis first contacts the guide plate 201, and under the action of the arc-shaped guide plate 201, the Angelica sinensis is directly guided into the interior of the separation cylinder 4. At this time, the electric hoist 6 starts to lift the front part of the separation cylinder 4. Due to the existence of the bearing 501 and the connecting rod 502, it is ensured that when the hook part of the electric hoist 6 lifts the connecting rod 502, it can effectively带动 the front end of the reinforcing rod 5 to lift. The lifting of the reinforcing rod 5 will lift the separation cylinder 4 together. At this time, the front end of the separation cylinder 4 tilts and the tail end of the reinforcing rod 5 swings upward under the support of the bearing seat. By starting the servo motor in the reduction gear 405, its output end increases the torque under the action of the reduction gear in the reduction gear 405 and is finally transmitted to the driving tooth 404, making it start to rotate. When the separation cylinder 4 starts to rotate, the large screen 401 at its top moves first. When the large screen 401 rotates downward and the small screen 402 rotates upward, the Codonopsis pilosula inside starts to roll, and at the same time of its own rolling, it will roll relatively on the inner wall of the separation cylinder 4 due to friction. The combination of the two makes the large pieces of soil attached to the Angelica sinensis start to fall off. Then, the fallen large pieces of soil are filtered by the large screen 401 and fall to the mud outlet below and are discharged. Further, by the continuous rotation of the driving tooth 404 to带动 the separation cylinder 4 to further rotate, its small screen 402 will reset to the lower part of the separation cylinder 4. At this time, as the Angelica sinensis continues to roll and turn, and at the same time accompanied by contact and collision with the "丰"-shaped guide plate 201, the small pieces of soil夹杂 in the root whiskers will be shaken off, and the small pieces of soil will be discharged to the mud outlet by the small screen 402.

The scope of the present invention is defined by the appended claims and their equivalents.
