DETAILED DESCRIPTION

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1, reference Figure 1 to Figure 9 , which is the first embodiment of the present invention, and this embodiment provides a screening device for harvesting deep-rooted and rhizome medicinal materials. The screening device for harvesting deep-rooted and rhizome medicinal materials includes a main body component 100, including a support frame 101, a support wheel 102, a mounting rod 103 and a harvesting piece 104. The support wheel 102 is 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, and the harvesting piece 104 is located below the support frame 101.

[0031] The support wheel 102 is used to support the support frame 101, the mounting rod 103 is used to connect the support frame 101 and the agricultural machinery, and the harvesting piece 104 is used to harvest the deep-rooted medicinal materials.

[0032] The screening component 200 is arranged on the harvesting member 104, and includes a first screen 201a arranged in the harvesting member 104, a second screen 201b is fixed on one side of the first screen 201a, a guide shell 201c is fixed on the top of the first screen 201a, a support seat 201d is fixed on the top of the second screen 201b, a rotating shaft 201e is rotatably connected in the support seat 201d, a fan gear 201f is fixed on the surface of the rotating shaft 201e, a rack 201g is slidably provided in the support seat 201d, a rotating rod 201h is rotatably connected in the support seat 201d, a connecting gear 201i is fixed on the surface of the rotating rod 201h, a supporting sleeve 201j is fixed on the surface of the rotating rod 201h, a connecting seat 201k is fixed on one side of the support sleeve 201j, and a cleaning plate 201l is fixed on one side of the connecting seat 201k.

[0033] The mesh openings of the first screen 201a are smaller than the mesh openings of the second screen 201b, so that the rhizomes of the medicinal materials are not easily buried under the soil again when they move on the top of the first screen 201a.

[0034] The guide shell 201c is used to support the rotating shaft 201e. When the rotating shaft 201e rotates, it can drive the fan gear 201f to move, so that the fan gear 201f drives 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 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, so that when the connecting seat 201k drives the cleaning plate 201l to swing, the cleaning plate 201l can slap the rhizomes of the medicinal materials, thereby cleaning the soil on the surface of the rhizomes of the medicinal materials, but because the cleaning plate 201l is made of a flexible material, the cleaning plate 201l will not cause damage to the rhizomes of the medicinal materials.

[0035] At the same time, the cleaning plate 2011 also has a certain supporting force, so that when the cleaning plate 2011 beats the rhizomes of the medicinal materials, it can drive the rhizomes of the medicinal materials to move toward the inner wall of the bucket 104a, thereby gathering the rhizomes of the medicinal materials, which is convenient for subsequent collection of the rhizomes of the medicinal materials.

[0036] 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, and the other end of the connecting rod 104d is rotatably connected to one side of the support frame 101 through a rotating shaft.

[0037] The bucket 104a is used to cut the soil so that the soil containing the rhizomes of the medicinal materials enters the bucket 104a. The design of the shovel teeth 104b makes it easier for the bucket 104a to cut the soil. Support shafts 104c and connecting rods 104d are provided on both sides of the bucket 104a. There are two connecting rods 104d on each side, so that the bucket 104a can move stably relative to the support frame 101, so that the shovel teeth 104b cut the soil through the reciprocating movement of the bucket 104a. When reciprocating, the bucket 104a will be displaced in the up and down directions, so that when the bucket 104a moves downward, the soil and the rhizomes of medicinal materials in the bucket 104a can be lifted up. At this time, the soil and the rhizomes of medicinal materials are in a suspended state, and at this time, the cleaning plate 201l begins to pat the rhizomes of medicinal materials, so as to facilitate the cleaning of the soil on the surface of the rhizomes of medicinal materials, and move the rhizomes of medicinal materials, so that the rhizomes of medicinal materials gather on one side of the inner wall of the bucket 104a, and as the bucket 104a reciprocates, the gathered rhizomes of medicinal materials are lifted up onto the ground.

[0038] Specifically, a swing rod 201m is fixed to the surface of the rotating shaft 201e, and the other end of the swing rod 201m is rotatably connected to a push rod 201n via a rotating shaft. The other end of the push rod 201n is rotatably connected to one side of the support frame 101 via a rotating shaft, and the rotating shaft 201e is rotatably connected to the bucket 104a.

[0039] When displacement occurs between the support frame 101 and the bucket 104a, the push rod 201n can push the swing rod 201m, so that the swing rod 201m drives the rotating shaft 201e to reciprocate.

[0040] Example 2, reference Figure 1 to Figure 9 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0041] Specifically, the main assembly 100 further includes a driving member 105 disposed in the support frame 101 , including a driving shaft 105 a rotatably connected to the support frame 101 , and a connecting plate 105 b is fixed to the end of the driving shaft 105 a .

[0042] The driving shaft 105 a can drive the connecting plate 105 b to rotate, and the driving shaft 105 a is disposed inside both sides of the supporting frame 101 .

[0043] 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 with the same connecting plate 105b, and one side of the connecting plate 105b is fixed with a driving column 105d.

[0044] Connecting plates 105b are fixed at both ends of the driving column 105d. 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.

[0045] Specifically, the driving member 105 further includes a first pulley 105e fixed to the surface of the driving column 105d, and a belt 105f is provided on the surface of the first pulley 105e.

[0046] The belt 105f is used to be connected to an external driving source, thereby driving the first pulley 105e to rotate, so that the first pulley 105e drives the driving column 105d to rotate.

[0047] Specifically, the driving member 105 further includes a protective shell 105g fixed to the bottom of the support frame 101 by bolts, and a mounting groove 105g-1 is provided on the protective shell 105g.

[0048] The protective shell 105g is used to protect the first pulley 105e to prevent mud from entering the first pulley 105e. The setting of the mounting groove 105g-1 allows the protective shell 105g to be snapped onto the driving column 105d and the surface of the first pulley 105e.

[0049] Specifically, the driving member 105 further includes a driving plate 105h rotatably connected to the surface of the moving column 105c, and a fixed column 105i is fixed to one side of the bucket 104a, and the driving plate 105h is rotatably connected to the surface of the fixed column 105i.

[0050] The movement of the movable column 105c can drive the driving plate 105h to reciprocate, so that the driving plate 105h drives the bucket 104a to reciprocate through the fixed column 105i, so that the bucket 104a cuts the soil through the shovel teeth 104b.

[0051] Specifically, the screening assembly 200 also includes a crushing piece 202, which is arranged in the support frame 101, including 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.

[0052] Both ends of the breaking rod 202e are fixed to the surface of the rotating disk 202d, and 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, and the driving rod 202c can drive the rotating disk 202d to rotate, so that the rotating disk 202d drives the breaking rod 202e to move, so that multiple breaking rods 202e break the soil.

[0053] Specifically, the crushing member 202 further includes a second pulley 202f fixed to the surface of the driving rod 202c, a third pulley 202g is fixed to the surface of the driving shaft 105a, and the second pulley 202f and the third pulley 202g are connected by a belt.

[0054] 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 disk 202d.

[0055] During use, when the rhizomes of medicinal materials are harvested, 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 slowly moves forward, the first pulley 105e drives the driving column 105d to rotate, so that the driving column 105d drives the connecting plates 105b at both ends to rotate synchronously, so that the connecting plate 105b drives the moving column 105c to move, and the movement of the moving column 105c can drive the driving plate 105h to reciprocate, so that the driving plate 105h drives the bucket 105h through the fixed column 105i. 4a moves back and forth, so that the bucket 104a cuts the soil through the shovel teeth 104b. As the agricultural machinery slowly moves forward, the soil wrapped with the rhizomes of the medicinal materials will move to the top of the first screen 201a. Since the mesh holes of the first screen 201a are smaller than the mesh holes of the second screen 201b, the rhizomes of the medicinal materials are not easily buried under the soil again when moving on the top of the first screen 201a. When the soil wrapped with the rhizomes of the medicinal materials moves to the side of the breaking rod 202e, it can be broken by the breaking rod 202e, so that the broken soil is sieved from the first screen 201a, and the rhizomes of the medicinal materials move from the first screen 201a to the guide shell 201c.

[0056] When the rhizomes of the medicinal materials move to the top of the guide shell 201c, as the bucket 104a moves downward, the rhizomes of the 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 fan gear 201f to move, so that the fan gear 201f drives 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, and 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, and when the connecting seat 201k drives the cleaning plate 201l to swing, the cleaning plate 201l can pat the rhizomes of the medicinal materials, thereby cleaning the soil on the surface of the rhizomes of the medicinal materials.

[0057] At the same time, the beating of the cleaning plate 2011 can drive the rhizomes of the medicinal materials to move toward the inner wall of the bucket 104a, thereby gathering the rhizomes of the medicinal materials, making it easier to collect them later.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
