Detailed implementation manners

[0029] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following provides a detailed description of the specific implementation manners of the present invention in conjunction with the accompanying drawings of the specification.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the spirit of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0031] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation manner of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that mutually excludes other embodiments.

[0032] Example 1, referring to Figures 1 to 9 , which is the first embodiment of the present invention. This embodiment provides a screening device for harvesting deep-rooted medicinal materials. The screening device for harvesting deep-rooted medicinal materials includes a main body component 100, which includes a support frame 101, support wheels 102, a mounting rod 103, and a harvesting component 104. The support wheels 102 are rotatably connected to one side of the support frame 101 through a rotating shaft. The mounting rod 103 is fixed to one side of the support frame 101. The harvesting component 104 is located below the support frame 101.

[0033] The support wheels 102 are used to support the support frame 101. The mounting rod 103 is used to connect the support frame 101 and the agricultural machinery. The harvesting component 104 is used to harvest deep-rooted medicinal materials.

[0034] The screening component 200 is arranged on the harvesting part 104 and includes a first screen 201a arranged inside the harvesting part 104. A second screen 201b is fixed to one side of the first screen 201a. A guiding shell 201c is fixed to the top of the first screen 201a. A supporting seat 201d is fixed to the top of the second screen 201b. A rotating shaft 201e is rotatably connected inside the supporting seat 201d. A sector gear 201f is fixed to the surface of the rotating shaft 201e. A rack 201g slides inside the supporting seat 201d. A rotating rod 201h is rotatably connected inside the supporting seat 201d. A connecting gear 201i is fixed to the surface of the rotating rod 201h. A supporting sleeve 201j is fixed to the surface of the rotating rod 201h. A connecting seat 201k is fixed to one side of the supporting sleeve 201j. A cleaning plate 201l is fixed to one side of the connecting seat 201k.

[0035] The mesh holes of the first screen 201a are smaller than those of the second screen 201b, so that when the medicinal material rhizomes move on the top of the first screen 201a, they are not easily buried under the soil again.

[0036] The guiding shell 201c is used to support the rotating shaft 201e. When the rotating shaft 201e rotates, it can drive the sector gear 201f to move, so that the sector gear 201f drives the rack 201g to move, thereby enabling the rack 201g to drive the connecting gear 201i to rotate, so as to drive the rotating rod 201h to rotate. The rotating rod 201h can drive the supporting sleeve 201j to rotate, so that the supporting sleeve 201j drives the connecting seat 201k to swing. The cleaning plate 201l is made of a flexible material with a certain supporting force. When the connecting seat 201k drives the cleaning plate 201l to swing, the cleaning plate 201l can pat the medicinal material rhizomes, thereby cleaning the soil on the surface of the medicinal material rhizomes. However, since the cleaning plate 201l is made of a flexible material, the cleaning plate 201l will not damage the medicinal material rhizomes.

[0037] At the same time, the cleaning plate 201l also has a certain supporting force, so that when the cleaning plate 201l pats the medicinal material rhizomes, it can drive the medicinal material rhizomes to move towards one side of the inner wall of the bucket 104a, thereby gathering the medicinal material rhizomes together, which is convenient for subsequent collection of the medicinal material rhizomes.

[0038] Specifically, the harvesting part 104 includes a bucket 104a arranged below the support frame 101. A shovel tooth 104b is fixed to one side of the bucket 104a. A support shaft 104c is fixed to one side of the bucket 104a. A connecting rod 104d is rotatably connected to the surface of the support shaft 104c. The other end of the connecting rod 104d is rotatably connected to one side of the support frame 101 through a rotating shaft.

[0039] The bucket 104a is used to cut the soil so that the soil containing the medicinal herb rhizomes enters the bucket 104a. The design of the bucket teeth 104b makes it easier for the bucket 104a to cut the soil. Support shafts 104c and connecting rods 104d are arranged on both sides of the bucket 104a. There are two connecting rods 104d on each side, enabling the bucket 104a to move stably relative to the support frame 101. Thus, through the reciprocating movement of the bucket 104a, the bucket teeth 104b cut the soil. When the bucket 104a reciprocates, the bucket 104a will displace in the up and down direction. When the bucket 104a moves downward, the soil and medicinal herb rhizomes in the bucket 104a can be lifted up. At this time, the soil and medicinal herb rhizomes are in a suspended state, and at this time, the cleaning plate 201l starts to pat the medicinal herb rhizomes, thereby facilitating the cleaning of the soil on the surface of the medicinal herb rhizomes and moving the medicinal herb rhizomes, causing the medicinal herb rhizomes to gather on one side of the inner wall of the bucket 104a. With the reciprocating movement of the bucket 104a, the gathered medicinal herb rhizomes are dumped onto the ground.

[0040] Specifically, a swing rod 201m is fixed on the surface of the rotating shaft 201e. The other end of the swing rod 201m is rotatably connected to a push rod 201n through a rotating shaft. The other end of the push rod 201n is rotatably connected to one side of the support frame 101 through a rotating shaft. The rotating shaft 201e is rotatably connected inside the bucket 104a.

[0041] When a displacement occurs between the support frame 101 and the bucket 104a, the push rod 201n can push the swing rod 201m, thereby causing the swing rod 201m to drive the rotating shaft 201e to rotate reciprocally.

[0042] Embodiment 2, referring to Figures 1 to 9 , is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0043] Specifically, the main body assembly 100 further includes a driving member 105, which is arranged inside the support frame 101 and includes a driving shaft 105a rotatably connected inside the support frame 101. A connecting plate 105b is fixed to the end of the driving shaft 105a.

[0044] The driving shaft 105a can drive the connecting plate 105b to rotate. The driving shafts 105a are arranged inside both sides of the support frame 101.

[0045] Specifically, the driving member 105 further includes a moving column 105c fixed to one side of the connecting plate 105b. The other end of the moving column 105c is fixed to the same connecting plate 105b. A driving column 105d is fixed to one side of the connecting plate 105b.

[0046] Both ends of the driving column 105d are fixed with connecting plates 105b. The driving column 105d can drive the connecting plates 105b at both ends to rotate synchronously, so that the connecting plates 105b drive the moving column 105c to move.

[0047] Specifically, the driving member 105 further includes a first pulley 105e fixed on the surface of the driving column 105d, and a belt 105f is arranged on the surface of the first pulley 105e.

[0048] The belt 105f is used to connect with an external driving source, so as to drive the first pulley 105e to rotate, and make the first pulley 105e drive the driving column 105d to rotate.

[0049] Specifically, the driving member 105 further includes a protective shell 105g fixed to the bottom of the support frame 101 by bolts, and an installation groove 105g-1 is provided on the protective shell 105g.

[0050] The protective shell 105g is used to protect the first pulley 105e and prevent soil from entering the first pulley 105e. The setting of the installation groove 105g-1 enables the protective shell 105g to be clamped to the surfaces of the driving column 105d and the first pulley 105e.

[0051] Specifically, the driving member 105 further includes a driving plate 105h rotatably connected to the surface of the moving column 105c. A fixing column 105i is fixed on one side of the bucket 104a, and the driving plate 105h is rotatably connected to the surface of the fixing column 105i.

[0052] By the movement of the moving column 105c, the driving plate 105h can be driven to move reciprocally, so that the driving plate 105h drives the bucket 104a to move reciprocally through the fixing column 105i, and then the bucket 104a cuts the soil through the shovel teeth 104b.

[0053] Specifically, the screening assembly 200 further includes a crushing member 202. The crushing member 202 is arranged in the support frame 101 and includes a support rod 202a fixed in the support frame 101. A fixed seat 202b is fixed at the bottom of the support rod 202a. A driving rod 202c is rotatably connected in the fixed seat 202b. A rotating disk 202d is fixed on one side of the driving rod 202c, and a crushing rod 202e is fixed on the other side of the rotating disk 202d.

[0054] Both ends of the crushing rod 202e are fixed to the surface of the rotating disk 202d. The support rod 202a is used to support the fixed seat 202b, so that the fixed seat 202b can stably support the driving rod 202c. The driving rod 202c can drive the rotating disk 202d to rotate, so that the rotating disk 202d drives the crushing rod 202e to move, and then multiple crushing rods 202e crush the soil.

[0055] Specifically, the crushing member 202 further includes a second pulley 202f fixed to the surface of the driving rod 202c, and a third pulley 202g is fixed to the surface of the driving shaft 105a. The second pulley 202f and the third pulley 202g are connected by a belt.

[0056] Through the transmission of the second pulley 202f and the third pulley 202g, the driving rod 202c can drive the crushing rod 202e to move through the rotating disc 202d.

[0057] During use, when harvesting the roots and rhizomes of medicinal materials, the support frame 101 is fixed to the agricultural machinery through the mounting rod 103, and the belt 105f is connected to drive the first pulley 105e to rotate. At this time, as the agricultural machinery moves forward slowly, the first pulley 105e drives the driving column 105d to rotate, causing the connecting plates 105b at both ends of the driving column 105d to rotate synchronously, and the connecting plates 105b drive the moving column 105c to move. Through the movement of the moving column 105c, the driving plate 105h can be driven to move reciprocally, so that the driving plate 105h drives the bucket 104a to move reciprocally through the fixed column 105i, and the bucket 104a cuts the soil through the shovel teeth 104b. As the agricultural machinery moves forward slowly, the soil containing the roots and rhizomes of medicinal materials will move to the top of the first screen 201a. Since the mesh holes of the first screen 201a are smaller than those of the second screen 201b, when the roots and rhizomes of medicinal materials move on the top of the first screen 201a, they are not easily buried under the soil again. When the soil containing the roots and rhizomes of medicinal materials moves to one side of the crushing rod 202e, it can be crushed by the crushing rod 202e, so that the crushed soil is sifted down from the first screen 201a, and the roots and rhizomes of medicinal materials move from the first screen 201a towards the guide housing 201c.

[0058] When the roots and rhizomes of medicinal materials move to the top of the guide housing 201c, as the bucket 104a moves downward, the roots and rhizomes of medicinal materials will be thrown up. At this time, the push rod 201n pulls the swing rod 201m, so that the swing rod 201m drives the rotating shaft 201e to rotate. At this time, the rotating shaft 201e can drive the sector gear 201f to move, causing the sector gear 201f to drive the rack 201g to move, so that the rack 201g drives the connecting gear 201i to rotate, thereby driving the rotating rod 201h to rotate. The rotating rod 201h can drive the support sleeve 201j to rotate, so that the support sleeve 201j drives the connecting seat 201k to swing. When the connecting seat 201k drives the cleaning plate 201l to swing, the cleaning plate 201l can pat the roots and rhizomes of medicinal materials to clean the soil on the surface of the roots and rhizomes of medicinal materials.

[0059] Meanwhile, the flapping of the cleaning plate 201l can drive the medicinal herb rhizomes to move towards the inner wall side of the bucket 104a, thereby gathering the medicinal herb rhizomes together, which is convenient for subsequent collection of the medicinal herb rhizomes.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
