Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural machinery equipment, and particularly relates to a Ligusticum chuanxiong cutting mechanism. BACKGROUND

[0002] Ligusticum chuanxiong is a plant of the Umbelliferae family, which is warm in nature and pungent in flavor, and has the effects of activating blood and qi, dispelling wind and relieving pain. Ligusticum chuanxiong rarely flowers and bears fruit, so the asexual reproduction mode of above-ground stem nodes (Ling seed) is adopted in production. Ligusticum chuanxiong stems with thick stem nodes and healthy internodes are selected, and the end of the stem towards the ground is cut into an oblique opening (so as to distinguish the direction and avoid reverse insertion), and a certain length of stem is left at both ends of the node disc to form an insertion sprout (Ling seed) with a length of 3-4 cm. In the planting season, the treated Ling seed is planted according to the plant row spacing of 15 cm x 20 cm, the bud is inserted into the soil upwards, the planting depth is preferably 1-2 cm with the stem node entering the soil, the node disc is half exposed, and 1-2 cm thick straw is covered after planting to reduce rain erosion and sun exposure, and the soil is kept moist after planting.

[0003] The stem of Ligusticum chuanxiong is long and rod-shaped, and the node discs on the stem are unevenly distributed. The artificial cutting mode is usually adopted to cut the Ligusticum chuanxiong stem in sections along the length direction of the Ligusticum chuanxiong stem to obtain the Ling seed. The cutting efficiency is low, the labor intensity is large, and the precision of artificial cutting is poor, which makes it difficult to guarantee the size accuracy and consistency of the Ling seed and affects the planting of the Ling seed. SUMMARY

[0004] The technical problem to be solved by the present application and the technical task proposed are to improve the prior art, provide a Ligusticum chuanxiong cutting mechanism, and solve the problems in the prior art that the Ligusticum chuanxiong stem is cut by artificial cutting, the labor intensity is large, the cutting precision is poor, and it is difficult to guarantee the size accuracy and consistency of the Ling seed.

[0005] To solve the above technical problems, the technical scheme of the present application is as follows:

[0006] A Ligusticum chuanxiong cutting mechanism, comprising a cutting unit for cutting the Ligusticum chuanxiong stem and a clamping unit for clamping the Ling seed, the cutting unit and the clamping unit are respectively provided with a plurality of intervals along a preset direction one, and the cutting unit and the clamping unit are movably adjustable along the preset direction one. The Ligusticum chuanxiong cutting mechanism can simultaneously cut the Ligusticum chuanxiong stem arranged along the preset direction one in the length direction in multiple sections, so as to simultaneously cut a plurality of Ling seeds, effectively improve the cutting efficiency, reduce the labor intensity, the clamping unit can clamp the cut Ling seed, facilitate the sorting of materials, facilitate the separation of the cut Ling seed and the discarded section, and the cutting unit and the clamping unit can be movably adjusted along the preset direction one, so as to accurately adapt the position of the node disc on the Ligusticum chuanxiong stem, effectively improve the cutting accuracy, improve the size accuracy and consistency of the obtained Ling seed, and be beneficial to the subsequent planting and growth of the Ling seed.

[0007] Further, the clamping unit is provided with a blowing assembly, which blows the seeds downward when the clamping unit is released. When the clamping unit releases the seeds, the seeds may adhere to the clamping unit, and the seeds cannot normally fall out of the material. The blowing assembly blows the seeds, so that the seeds can reliably fall out of the material. When the clamping unit releases the seeds to directly fall downward, the seeds are easily blocked by the lower components, which affects the reliability of the falling. Therefore, the blowing assembly blows the seeds, so that the seeds can have a certain amount of movement in the transverse direction, and the reliability of the falling is improved.

[0008] Further, the clamping unit is provided with a blowing assembly, which blows the seeds downward when the clamping unit is released. When the clamping unit releases the seeds, the seeds may adhere to the clamping unit, and the seeds cannot normally fall out of the material. The blowing assembly blows the seeds, so that the seeds can reliably fall out of the material. When the clamping unit releases the seeds to directly fall downward, the seeds are easily blocked by the lower components, which affects the reliability of the falling. Therefore, the blowing assembly blows the seeds, so that the seeds can have a certain amount of movement in the transverse direction, and the reliability of the falling is improved.

[0009] Further, the clamping unit is provided with a blowing assembly, which blows the seeds downward when the clamping unit is released. When the clamping unit releases the seeds, the seeds may adhere to the clamping unit, and the seeds cannot normally fall out of the material. The blowing assembly blows the seeds, so that the seeds can reliably fall out of the material. When the clamping unit releases the seeds to directly fall downward, the seeds are easily blocked by the lower components, which affects the reliability of the falling. Therefore, the blowing assembly blows the seeds, so that the seeds can have a certain amount of movement in the transverse direction, and the reliability of the falling is improved.

[0010] Further, the clamping unit is provided with a blowing assembly, which blows the seeds downward when the clamping unit is released. When the clamping unit releases the seeds, the seeds may adhere to the clamping unit, and the seeds cannot normally fall out of the material. The blowing assembly blows the seeds, so that the seeds can reliably fall out of the material. When the clamping unit releases the seeds to directly fall downward, the seeds are easily blocked by the lower components, which affects the reliability of the falling. Therefore, the blowing assembly blows the seeds, so that the seeds can have a certain amount of movement in the transverse direction, and the reliability of the falling is improved.

[0011] Further, the preset direction one is along the vertical direction, that is, the shearing unit and the clamping unit are spaced along the vertical direction, and the length direction of the chuanxiong stem to be sheared is also along the vertical direction. The chuanxiong shearing mechanism has a vertical structure, which can improve the shearing efficiency, reduce the occupied area, and improve the structural compactness of the equipment.

[0012] Further, the shearing unit and the clamping unit are connected as a whole, have high integration, and occupy a small volume. The relative movement of the shearing unit and the chuanxiong stem for feeding and retracting requires that the driving mechanism for driving the shearing unit to feed and retract and the moving mechanism for driving the clamping unit to move are shared, which greatly improves the integration and reduces the overall power consumption of the chuanxiong shearing mechanism, and is beneficial to the layout of the power source for driving the shearing unit and the clamping unit to move, and reduces the overall volume.

[0013] Further, the functional units formed by the shearing unit and the clamping unit are respectively driven by the adjusting mechanism to move along the preset direction one, which improves the automation degree and the adjusting precision, and better improves the shearing precision of the chuanxiong stem.

[0014] Further, each shearing unit comprises two shearing members spaced along the preset direction one. The seedling contains the node disc on the chuanxiong stem and a small section of the stem reserved at both ends of the node disc. The distance between the adjacent node discs on the whole chuanxiong stem is relatively long, and the stem between the adjacent node discs cannot be cut once to obtain the seedling. Instead, the stem between the adjacent node discs needs to be cut twice to obtain the seedling with a size meeting the requirements. The shearing unit of the present application comprises two shearing members, which can simultaneously shear the axial ends of the node disc. When shearing, the node disc is located between the two shearing members, and each shearing unit can obtain the seedling after one action.

[0015] Further, on the preset direction one, each clamping unit is located between the two shearing members of each shearing unit. Before the shearing members shear the chuanxiong stem, the clamping unit clamps the node disc or the stem near the node disc. After the shearing members complete the shearing action, the sheared seedling is clamped by the clamping unit, which is convenient for subsequent sorting of the seedling appearance.

[0016] Further, the shearing member comprises a cutting tool and a power mechanism for driving the cutting tool to move. The two shearing members in each shearing unit share one power mechanism. The structure is simple and compact, which is beneficial to reducing the volume and cost. The two shearing members can move synchronously, which ensures the shearing efficiency.

[0017] Compared with the prior art, the present application has the following advantages:

[0018] The chuanxiong cutting mechanism can simultaneously cut multiple sections of chuanxiong stems, and can simultaneously cut multiple chuanxiong seeds, effectively improving the cutting efficiency and reducing the labor intensity. The cutting unit and the clamping unit can be flexibly adjusted according to the position of the node disc on the chuanxiong stem, effectively improving the cutting accuracy, improving the size accuracy and consistency of the obtained chuanxiong seeds, and being beneficial to the subsequent planting and growth of the chuanxiong seeds.

Detailed Implementation

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0035] This invention discloses a chuanxiong seed-cutting mechanism, which effectively improves the efficiency and precision of seed cutting, enhances the size accuracy and consistency of the obtained chuanxiong seeds, and is beneficial for subsequent planting and the growth and development of the chuanxiong seeds.

[0036] Example 1

[0037] like Figure 1 As shown, a Ligusticum striatum cutting mechanism mainly includes a cutting unit 1 and a clamping unit 2. The cutting unit 1 is used to cut the Ligusticum striatum stems, and the clamping unit 2 is used to clamp the Ligusticum striatum seeds. Before the Ligusticum striatum stems are cut, the clamping unit 2 clamps the node plate or the vicinity of the node plate. After cutting, the clamping unit 2 clamps the Ligusticum striatum seeds. Several cutting units 1 and clamping units 2 are arranged at intervals along a preset direction. The cutting unit 1 and the clamping unit 2 correspond one-to-one. By arranging the length direction of the Ligusticum striatum stems 6 along the preset direction, the Ligusticum striatum cutting assembly can simultaneously cut multiple segments of the Ligusticum striatum stems, thereby obtaining multiple Ligusticum striatum seeds at the same time. Specifically, each clamping unit 2 clamps the Ligusticum striatum seeds. The cutting unit 1 cuts the stem of *Ligusticum chuanxiong* at a node or near a node, and the remaining part on the clamping unit 2 is the desired *Ping* seed. Preferably, the cutting unit 1 and the clamping unit 2 are adjustable along a preset direction, so that the cutting unit 1 and the clamping unit 2 can be flexibly and precisely adjusted according to the position of the node on the *Ligusticum chuanxiong* stem. The node distribution on the *Ligusticum chuanxiong* stem is uneven, and the position of the node on different *Ligusticum chuanxiong* stems will also be different. The cutting unit 1 and the clamping unit 2 are flexibly and precisely adjusted according to the actual position of the node on each *Ligusticum chuanxiong* stem to ensure cutting accuracy and to ensure that the clamping unit 2 accurately clamps the *Ping* seed, thereby improving the size accuracy and consistency of the obtained *Ping* seed.

[0038] like Figure 2The distance between the adjacent node discs on the shown Ligusticum chuanxiong stem is long, and the total length of the Ligusticum seedling 61 is about 4 cm. The Ligusticum seedling only reserves a small section of the stem at the two ends of the node disc axis. The upper end stem is about 1 cm long, and the lower end stem is about 3 cm long. Therefore, the stem between the adjacent node discs cannot be cut once to obtain the Ligusticum seedling with the required size. Usually, the stem between the adjacent node discs needs to be cut twice to obtain the Ligusticum seedling with the required size, so that a section of the stem between the adjacent node discs needs to be discarded, which is defined as the discarded section 62. If only the shearing unit 1 is used to shear the Ligusticum chuanxiong stem, the Ligusticum seedling 61 and the discarded section 62 will be discharged together and mixed. Only the Ligusticum seedling has the function of planting. The Ligusticum seedling 61 and the discarded section 62 need to be sorted. The discharge of the Ligusticum seedling 61 and the discarded section 62 together increases the difficulty of subsequent sorting. The embodiment uses the clamping unit 2 to clamp the Ligusticum seedling obtained by shearing, so that the Ligusticum seedling and the discarded section are discharged separately, which is convenient for sorting of the material and is beneficial to subsequent appearance sorting of the Ligusticum seedling (different node disc diameters are different appearance levels of the Ligusticum seedling).

[0039] As Figure 1 shown, the preset direction one is a straight line direction, that is, the shearing units 1 and the clamping units 2 are spaced apart along the straight line direction, and each shearing unit 1 and clamping unit 2 is flexibly adjustable in the straight line direction. The shearing unit 1 is spaced apart along the straight line direction, which is easy to design the structure layout, is convenient to set the guide mechanism and the like, and ensures that the shearing unit 1 and the clamping unit 2 can be accurately adjusted along the preset straight line direction, thereby ensuring the shearing accuracy. In addition, although the Ligusticum chuanxiong stem is long and rod-shaped, it has a certain natural curvature. Straightening the Ligusticum chuanxiong stem along the straight line can make the positions of each node disc on the Ligusticum chuanxiong stem more clear, thereby facilitating accurate adjustment of the positions of the shearing unit 1 and the clamping unit 2 to match the positions of each node disc, thereby improving the shearing accuracy and the clamping accuracy. In addition, straightening the Ligusticum chuanxiong stem along the straight line is also easy to implement. The jig is used to clamp the two ends of the Ligusticum chuanxiong stem, and the straight line distance between the two end clamps is increased to effectively straighten the Ligusticum chuanxiong stem along the straight line. Of course, the preset direction one can also be a curved direction. The Ligusticum chuanxiong stem needs to be straightened along the curved direction by using a jig with a curve. Compared with the straight line direction of the preset direction one, the arrangement of the shearing unit 1 and the clamping unit 2 is more complex.

[0040] As Figure 1As shown, all shearing units 1 can be slidably connected to the same linear slide rail assembly, while all clamping units 2 are slidably connected to another linear slide rail assembly. Each shearing unit 1 and each clamping unit 2 is independently adjustable on the linear slide rail assembly. The position of each shearing unit 1 can be adjusted by manually pushing the shearing unit 1 and clamping unit 2, so that each shearing unit 1 accurately matches the position of each node disc on the Ligusticum striatum stem, thereby ensuring shearing and clamping accuracy. The distribution position of the node discs on each Ligusticum striatum stem is different. Therefore, when shearing each new Ligusticum striatum stem, it is generally necessary to adjust the position of each shearing unit 1 and clamping unit 2. Manual adjustment is labor-intensive. Figure 3 As shown, each shearing unit 1 and each clamping unit 2 is driven by an adjustment mechanism 3 to move along a preset direction, thereby improving automation, reducing labor intensity, increasing adjustment efficiency and precision, and ultimately improving the overall shearing efficiency. The adjustment mechanism 3 can be a cylinder, hydraulic cylinder, electric push rod, lead screw, or other mechanism. The driving direction of the adjustment mechanism 3 is along the preset direction, enabling the shearing unit 1 and clamping unit 2 to be precisely adjusted according to the specific distribution position of the nodes on the stem of *Ligusticum striatum*. The specific distribution position of the nodes on the stem of *Ligusticum striatum* can be accurately obtained through image recognition or other methods. The adjustment mechanism 3 then automatically adjusts the position of the shearing unit 1 and clamping unit 2 based on the specific distribution position of the nodes obtained by image recognition, which can greatly reduce labor intensity and improve shearing efficiency and automation.

[0041] Furthermore, such as Figure 4As shown, the clamping unit 2 is driven by the moving mechanism 4 to move between the shearing position and the discharging position. When the clamping unit 2 is in the shearing position, the clamping unit 2 clamps the part of the Ligusticum chuanxiong hort on the Ligusticum chuanxiong hort stem for the shearing unit 1 to shear. When the clamping unit 2 is in the discharging position, the clamping unit 2 releases the Ligusticum chuanxiong hort for discharging. The moving direction of the moving mechanism 4 can be defined as a preset direction two, which can be a straight line direction perpendicular to the preset direction one. After the shearing unit 1 performs the shearing action on the Ligusticum chuanxiong hort stem, the discarded section directly falls out of the discharging position, while the Ligusticum chuanxiong hort is clamped on the clamping unit 2 and does not fall out of the discharging position with the discarded section. The moving mechanism 4 drives the clamping unit 2 to move along the preset direction two, so that the Ligusticum chuanxiong hort is moved to another position to leave the discharging position of the discarded section, and then the clamping unit 2 releases the Ligusticum chuanxiong hort for discharging. The above process conveniently and simply realizes the sorting of the material. The preset direction two can also be other directions, as long as the Ligusticum chuanxiong hort and the discarded section can be discharged from different positions respectively. The moving mechanism 4 can drive the clamping unit 2 to move to multiple discharging positions along the preset direction two, so that the Ligusticum chuanxiong hort can be sorted according to the appearance. The diameter of each node on the Ligusticum chuanxiong hort stem can be obtained by image recognition, and then the moving mechanism 4 drives the clamping unit 2 clamping the Ligusticum chuanxiong hort to move, so that the Ligusticum chuanxiong hort of different appearances is released from different discharging positions, thereby conveniently realizing the appearance sorting of the Ligusticum chuanxiong hort. Specifically, each clamping unit 2 can be independently driven by a moving mechanism 4 to move along the preset direction two, so that each clamping unit 2 is driven by the corresponding moving mechanism 4 to move to a discharging position meeting the appearance requirement for discharging. Alternatively, as shown in Figure 4 all the clamping units 2 are integrally driven by a moving mechanism 4 to move along the preset direction two. The moving mechanism 4 can be a linear moving mechanism, which can be a pneumatic cylinder, a hydraulic cylinder, an electric push rod, a screw pair mechanism, etc. The moving mechanism 4 integrally drives all the clamping units 2 to move. When all the clamping units 2 integrally move to a discharging position, the clamping unit 2 releases the Ligusticum chuanxiong hort meeting the appearance requirement of the discharging position, while the Ligusticum chuanxiong hort not meeting the appearance requirement is still clamped by the clamping unit 2. Then all the clamping units 2 integrally move to another discharging position, and the clamping unit 2 releases the Ligusticum chuanxiong hort meeting the appearance requirement of the discharging position. In this way, the appearance sorting of the Ligusticum chuanxiong hort is realized.

[0042] The Ligusticum chuanxiong hort shearing mechanism described in the embodiment can be a vertical structure or a horizontal structure, i.e., the preset direction one is vertical or horizontal, so that Figure 4The chuanxiong seed cutting mechanism can be a side view of a vertical structure or a top view of a horizontal structure. When a vertical structure is adopted, the clamping units 2 are arranged vertically and spaced apart, so that the next layer of clamping units 2 is below the chuanxiong seeds clamped by the clamping units 2. Therefore, if the clamping units 2 are directly released, the chuanxiong seeds will be blocked by the clamping units 2 below, which is not conducive to smooth discharging. Each clamping unit 2 can be independently driven by a moving mechanism 4 to move along a predetermined direction, so that the clamping units 2 can be offset from each other, ensuring that the chuanxiong seeds can be smoothly discharged without obstruction when the clamping units 2 are released. When a horizontal structure is adopted, the clamping units 2 are arranged horizontally and spaced apart, so that there is no obstruction below the chuanxiong seeds when the clamping units 2 are released, and the chuanxiong seeds can be smoothly discharged.

[0043] When the clamping units 2 clamp and release the chuanxiong seeds, the chuanxiong seeds may adhere to the clamping units. When the clamping units 2 release the chuanxiong seeds, the chuanxiong seeds will fall straight along the direction of gravity and be easily blocked by the components below (for example, when the chuanxiong seed cutting mechanism adopts a vertical structure), which affects the reliability of discharging. Therefore, as shown in Figure 5 The clamping units 2 are provided with a blowing assembly 21, which blows the chuanxiong seeds to discharge when the clamping units 2 release the chuanxiong seeds. The blowing assembly 21 mainly includes a gas nozzle connected to a gas source through a gas pipe. The blowing assembly 21 blows high-pressure gas to blow the chuanxiong seeds, so that the chuanxiong seeds can be reliably discharged, avoiding adhesion to the clamping units 2. The chuanxiong seeds fall along a parabolic trajectory, avoiding being blocked by the components below, and improving the reliability of discharging.

[0044] The diameters of the nodes of the chuanxiong seeds are different, so the weights of each chuanxiong seed are different, and the adhesion of the chuanxiong seeds to the clamping units is also different. The moving distance of the chuanxiong seeds under the blowing action of the blowing assembly is different. In other words, the chuanxiong seeds are difficult to fall to an accurate position under the blowing action of the blowing assembly, which is not conducive to accurate sorting. Therefore, as shown in Figure 6 and Figure 7As shown, the baffle mechanism 5 is arranged to guide the seedlings, which includes a baffle 51 and a baffle driving mechanism 52, the baffle 51 is driven by the baffle driving mechanism 52 to switch between the blocking position and the avoiding position, when the baffle 51 is in the blocking position, the baffle 51 is located on the path of the seedlings blown by the air blowing assembly 21 to block and guide the seedlings to fall, when the baffle 51 is in the avoiding position, the baffle 51 avoids the clamping unit 2 to ensure that the clamping unit 2 can normally clamp the seedlings, avoiding the baffle 51 blocking between the clamping unit 2 and the chuanqiong stem to hinder the clamping unit 2 normally clamping the position of the seedlings on the chuanqiong stem, the baffle 51 can switch between the blocking position and the avoiding position in a linear sliding manner, similar to a sliding door structure, the baffle 51 can also switch between the blocking position and the avoiding position in a deflection manner, similar to a casement door structure, in this embodiment, all clamping units 2 share a baffle mechanism 5, that is, only a single baffle 51 is arranged, the baffle 51 is a vertical plate, when the baffle 51 is in the blocking position, it can simultaneously block and guide the seedlings on all clamping units 2, the baffle mechanism 5 as a whole is in a position-fixed state relative to the clamping unit 2, the baffle mechanism 5 as a whole moves along the preset direction two under the driving of the moving mechanism 4, when the chuanqiong seedling cutting mechanism works, the baffle mechanism 5 is first in a state that the baffle 51 is in the avoiding position, the clamping unit 2 is driven by the moving mechanism 4 to approach the chuanqiong stem, the clamping unit 2 clamps the part of the chuanqiong stem where the seedlings are located, then the cutting unit 1 cuts the chuanqiong stem to make the seedlings cut and separated from the chuanqiong stem, the discarded segment 62 directly falls into the material frame, then the clamping unit 2 reversely moves under the driving of the moving mechanism 4, then the baffle mechanism 5 switches to the state that the baffle 51 is in the blocking position, the moving mechanism 4 drives the clamping unit 2 and the baffle mechanism 5 as a whole to move to the position where the seedlings are required to be discharged, the clamping unit 2 releases the seedlings and the air blowing assembly 21 blows the seedlings, so that the seedlings fall along a parabolic path after being blown out, then the seedlings hit the baffle 51 to be blocked and guided by the baffle 51 to fall into the corresponding material frame, so that the discharge is more accurate.

[0045] As Figure 1 , Figures 3 to 5 and Figure 8As shown, each of the shearing units 1 respectively only contains one shearing member 11, which refers to a device for cutting off the Ligusticum chuanxiong stem, and the shearing member 11 can be various devices with cutting function, and specifically can be an electric saw, a cutter, a scissors and the like, and based on the material properties of the Ligusticum chuanxiong stem, a cutter, a scissors and the like can be preferably adopted, which can guarantee reliable cutting while guaranteeing simple and compact structure, easy implementation, low cost, low driving power consumption, and specifically, the shearing member 11 comprises a cutting tool 12 and a power mechanism 13 for driving the cutting tool 12 to act, the power mechanism 13 is a power source for driving the cutting tool 12 to act, and the power mechanism 13 can be a pneumatic cylinder, a hydraulic cylinder, a speed reducer motor and the like, and the cutting tool 12 can specifically adopt a cutter, a scissors and the like, and the power mechanism 13 drives the cutting tool 12 to act, replacing manual operation, improving the degree of automation, effectively reducing the labor intensity, and improving the efficiency and precision of shearing operation. In the embodiment, the scissors adopted by the cutting tool 12 comprises a scissors blade one 121 and a scissors blade two 122, which are hinged on the base body 15 of the shearing member 11, and the scissors blade one 121 and the scissors blade two 122 are respectively connected with the power mechanism 13 arranged on the base body 15 through a crank connecting rod mechanism 14, and the power mechanism 13 specifically adopts a pneumatic cylinder, and the linear motion of the power mechanism 13 drives the scissors blade one 121 and the scissors blade two 122 to rotate through the crank connecting rod mechanism 14 to shear the Ligusticum chuanxiong stem, which has simple and compact structure, small space occupation, easy implementation, low cost, high action reliability, can guarantee reliable cutting of the Ligusticum chuanxiong stem, and guarantee the efficiency of shearing the Ligusticum chuanxiong stem to obtain the Ligusticum chuanxiong seed.

[0046] When each of the shearing units 1 respectively only contains one shearing member 11, the position of the shearing unit 1 is adjusted to make each shearing unit 1 respectively face the axial side of the node disc corresponding thereto to cut off, and then each shearing unit 1 moves to the other side of the node disc axis (or the Ligusticum chuanxiong stem moves relative to the Ligusticum chuanxiong shearing assembly to make each shearing unit 1 align with the other side of the node disc axis) to cut off, so as to obtain the Ligusticum chuanxiong seed 61 with the required size, and the adjacent Ligusticum chuanxiong seeds 61 are the excess discarded segments 62. The Ligusticum chuanxiong shearing assembly in the embodiment can simultaneously perform multi-segment shearing on a single Ligusticum chuanxiong stem, and the Ligusticum chuanxiong shearing assembly can simultaneously obtain multiple Ligusticum chuanxiong seeds through two shearing actions, effectively improving the shearing efficiency, and the Ligusticum chuanxiong shearing assembly in the embodiment contains a small number of shearing members, for example, eight node discs are distributed on the Ligusticum chuanxiong stem, and the Ligusticum chuanxiong shearing assembly only needs to be composed of 8 shearing members, which has few setting components and low implementation cost.

[0047] As Figure 9As shown, the shearing unit 1 has an even number, each of which contains a shearing member 11, and each adjacent two shearing units 1 form a group, and the two shearing units 1 in the group cooperate to shear the axial ends of the node disc on the chuanxiong stem at the same time, that is, the chuanxiong stem is sheared, and at the axial ends of each node disc, there is a shearing unit 1, so that the shearing unit 1 is twice the number of node discs, for example, there are eight node discs on the chuanxiong stem, and the chuanxiong shearing assembly needs to have 16 shearing units 1, that is, 16 shearing members 11, and all the shearing members 11 act at the same time to shear the axial ends of each node disc at the same time, that is, the chuanxiong shearing assembly only needs to act once to obtain the seed, compared with the first embodiment, the number of shearing members 11 is relatively large, but the shearing efficiency is higher, further improving the seed efficiency and shortening the shearing processing time.

[0048] As shown in Figure 10 Each of the shearing units 1 contains two shearing members 11 arranged at intervals along the preset direction, and the interval of the two shearing members 11 in the preset direction is fixed or adjustable. In the preset direction, each of the clamping units 2 is located between the two shearing members 11 of each of the shearing units 1, and the node disc on the chuanxiong stem is located between the two shearing members 11 during shearing, that is, the two shearing members 11 are located on both sides of the node disc in the axial direction. Before the shearing unit 1 performs the shearing action, the clamping unit 2 clamps the part of the chuanxiong stem where the seed is located, and then the shearing members 11 of each shearing unit 1 perform the shearing action at the same time to shear the seed at one time, Figure 10 As shown in Figure 9 The chuanxiong seed shearing mechanism can achieve the same technical effect, that is, one action can simultaneously shear multiple seeds at one time, improve the efficiency of seed shearing, and shorten the shearing processing time.

[0049] Example two

[0050] As shown in Figures 11 to 13As shown, the shearing unit 1 is connected with the clamping unit 2 as a whole, the integration degree is improved, and the occupied volume is reduced. Each shearing unit 1 comprises two shearing members 11 arranged at an interval along a preset direction. The clamping unit 2 is arranged between the two shearing members 11 of each shearing unit 1. The clamping unit 2 is also provided with a blowing assembly 21 to ensure reliable discharging. A moving mechanism 4 is used to drive the clamping unit 2 to move along a preset direction II, and the shearing unit 1 is also driven to move along the preset direction II, so that the shearing unit 1 is driven to move in a direction perpendicular to the length direction of the chuanxiong stem to perform feeding and retracting. The moving mechanism 4 realizes multiple functions, i.e., sorting of materials, driving the shearing unit 1 to feed and retract, and also provided with a baffle mechanism 5. The baffle mechanism 5 comprises a baffle 51 and a baffle driving mechanism 52. The baffle 51 is driven by the baffle driving mechanism 52 to switch between a blocking position and an avoiding position. When the baffle 51 is in the blocking position, the baffle 51 is located on the path of the seeds blown by the blowing assembly 21 to block and guide the seeds to fall. The baffle mechanism 5 as a whole moves along the preset direction II under the driving of the moving mechanism 4 together with the shearing unit 1 and the clamping unit 2. Specifically, a base member can be provided. The base member is provided with a plurality of shearing units 1 and clamping units 2 distributed along a preset direction I, and the shearing units 1 and the clamping units 2 are connected as a whole functional unit. Each functional unit has a freedom degree of movement along the preset direction I. Each functional unit is driven by an adjusting mechanism 3 to move along the preset direction I. The base member is also provided with a baffle mechanism 5. The base member as a whole is driven by the moving mechanism 4 to move along the preset direction II. In order to improve the stability and accuracy of the movement of the base member along the preset direction II, a guide sliding mechanism can be provided to guide and limit the movement of the base member.

[0051] Specifically, the interval of the two shearing members 11 on each shearing unit 1 along the preset direction I is fixed or adjustable. After the two shearing members 11 on each shearing unit 1 act, the seeds located between the two shearing members 11 are obtained, and the interval between the two shearing members 11 is the length of the seeds. During shearing, the node disc on the chuanxiong stem is located between the two shearing members 11, i.e., the two shearing members 11 are respectively located on both sides of the node disc in the axial direction, so that each shearing unit 1 can obtain a plurality of seeds at a time after one action. In other words, the chuanxiong seed cutting mechanism can simultaneously cut a plurality of seeds at a time after one action, thereby improving the efficiency of seed cutting and shortening the shearing processing time. The clamping unit 2 located between the two shearing members 11 directly clamps the cut seeds, and then moves to the required position together with the shearing unit 1 under the driving of the moving mechanism 4 to discharge, thereby conveniently sorting the materials.

[0052] In the embodiment, the vertical structure is adopted for the chuanxiong cutting mechanism, that is, the cutting unit 1 and the clamping unit 2 are connected as a functional unit and are vertically spaced, the next layer of functional unit is below the chuanxiong clamped by the clamping unit 2, and the chuanxiong is directly released by the clamping unit 2. The situation that the chuanxiong is blocked by the functional unit below occurs, so the air blowing assembly 21 is used to blow the chuanxiong, the air outlet direction of the air blowing assembly 21 is along the horizontal direction, so that the chuanxiong falls in a parabolic manner to avoid the next layer of functional unit, improves the reliability of the discharge, and the chuanxiong falls in a parabolic manner and hits the baffle 51 in the blocking position, so that the chuanxiong can accurately fall into the material frame below, and the accuracy of the sorting is improved.

[0053] In the embodiment, the two cutting members 11 in each cutting unit 1 share a power mechanism 13, the structure is more compact, the occupied volume is reduced, and the synchronous action of the two cutting members 11 in each cutting unit 1 is ensured, the cutting reliability and efficiency are improved, specifically, a single power mechanism 13 is respectively connected with a cutting tool 12 through a crank connecting rod mechanism 14, and the two cutting tools 12 in each cutting unit 1 share a rotating shaft, that is, the rotating shafts of a group of shear blades one 121 and shear blades two 122 on the base body 15 are coaxial with the rotating shafts of another group of shear blades one 121 and shear blades two 122 on the base body 15, the structure is compact, and the synchronous action of the two cutting tools 12 on each cutting unit 1 is ensured, thereby efficiently cutting the chuanxiong stems to obtain chuanxiong.

[0054] The above is only the preferred embodiment of the present application, and it should be pointed out that the above preferred embodiment should not be regarded as a limitation of the present application, and the protection scope of the present application should be limited by the scope defined by the claims. For ordinary skilled in the art, several improvements and refinements can be made without departing from the spirit and scope of the present application, and these improvements and refinements should also be regarded as the protection scope of the present application.
