Description

Technical Field

[0001] The present invention relates to the field of medicinal material harvesting devices, and more particularly to a bulb medicinal material harvesting device. Background Art

[0002] Bulbous medicinal materials are one of the most extensive categories of Chinese medicinal materials, and they play an indispensable role in the Chinese medicinal materials industry. The stems of bulbous medicinal materials usually grow on the soil, and their fruits usually grow in the soil, and sometimes they are accompanied by many complex and intertwined thin rhizomes that also grow in the soil. Therefore, they are closely integrated with the soil, which brings considerable challenges to the mechanized harvesting of their fruits.

[0003] The existing equipment for harvesting bulbous medicinal materials is mainly a traditional Chinese medicine harvester, which has a general structure of two inclined conveyor chain structures inside a box, and a plow blade is arranged on one side of the box. A tractor drives the box to move so that the plow blade penetrates into the soil, and the soil together with the fruits of the bulbous medicinal materials are plowed into the box. In the process of moving forward, the soil and the fruits of the bulbous medicinal materials are respectively rolled and sieved on the two inclined conveyor chain structures, thereby completing the effect of separating the fruits of the bulbous medicinal materials from the soil. The separated fruits of the bulbous medicinal materials are discharged through the conveyor chain structure at the rear end, making it convenient for workers to pick them up.

[0004] Based on the above inventors' discovery during actual use, although the existing Chinese medicine harvesters have many advantages, when the soil is plowed into the interior of the box together with the fruits of the bulbous medicinal materials, the fruits of the bulbous medicinal materials will first enter the first-stage conveyor chain structure in the form of a large amount of soil, and then roll and vibrate on the first-stage conveyor chain structure before entering the second-stage conveyor chain structure. The connection between the first-stage conveyor chain structure and the second-stage conveyor chain structure lacks a patting and poking structure for the fruits mixed with a large amount of soil, which is not conducive to separating the soil from the many complex and intertwined fine rhizomes and fruits. Therefore, we proposed a bulbous medicinal material harvesting device to solve the above-mentioned problems. Summary of the invention

[0005] 1. Technical issues to be solved

[0006] In view of the problems existing in the prior art, the purpose of the present invention is to provide a bulb medicinal material harvesting device, which can drive the rotating shaft five and the rotating shaft six to rotate simultaneously after the drive shaft access end is connected to the power output shaft of the tractor, and then can drive the conveying chain structure inside the box to work simultaneously through the connection between the sprocket three and the chain one, so that after the soil is plowed by a plurality of plow blades, the soil mixed with many complex and intertwined fine rhizomes and fruits can first reach the first conveying chain structure, then enter the soil poking structure, and finally enter the next conveying chain structure, thereby completing the effect of separating the soil from the complex and intertwined fine rhizomes and fruits during the conveying and shaking process of the two conveying chain structures, making it convenient for workers to pick up the complex and intertwined fine rhizomes and fruits;

[0007] At the same time, when the soil mixed with many complex and intertwined fine rhizomes and fruits enters the next conveyor chain structure from the first conveyor chain structure, the connection between the rotating shaft six, the sprocket six and the chain three can simultaneously drive the sprocket one of the two swing arm structures on the soil poking structure to rotate, thereby causing the rotating disks on the two swing arm structures to rotate. At this time, the connection between the connecting piles, the bar travel holes and the connecting rods can drive several arc-shaped arms to perform reciprocating deflection motion, prompting the contact pieces on the arc-shaped arms to continuously beat and poke the soil and the complex and intertwined fine rhizomes and fruits at the top of the guide inclined mesh plate through the avoidance opening, thereby accelerating the separation of the soil from the complex and intertwined fine rhizomes and fruits and improving the separation efficiency.

[0037] The conveying chain structure 13 also includes a group of shaft seats four respectively fixedly installed on both sides of the outer wall of the box body 1, and the group of shaft seats four are rotatably connected by a rotating shaft four 19, and both ends of the rotating shaft four 19 pass through the outside of the box body 1, and a sprocket four 20 is fixedly installed at the end of the rotating shaft four 19 located outside the box body 1, and the other end of one of the rotating shafts three 14 located inside the box body 1 passes through the outside of the box body 1, and a sprocket five 21 is fixedly installed at the end of the other end of one of the rotating shafts three 14, and the sprocket four 20 and the sprocket five 21 are connected by a chain two 22, and a group of elliptical wheels 23 are fixedly installed on the rotating shaft four 19 located inside the box body 1;

[0038] Two groups of shaft seats 5 are respectively fixedly welded on the outer wall of the box body 1 at the positions of the two conveyor chain structures 13 through two groups of brackets, and the two groups of shaft seats 5 are rotatably connected through a rotating shaft 5 24 and a rotating shaft 6 25, respectively. A steering gear 1 26 and a steering gear 2 27 are respectively arranged on the rotating shaft 5 24 and the rotating shaft 6 25, and the coupling ends of the steering gear 1 26 and the steering gear 2 27 are connected through a transmission shaft 28, and a drive shaft access end 2601 is arranged on one side of the steering gear 1 26;

[0039] The sprockets 3 17 on the two conveying chain structures 13 are fixedly mounted on the rotating shaft 5 24 and the rotating shaft 6 25 respectively, and a sprocket 6 11 is also fixedly mounted on the end of one end of the rotating shaft 6 25, and the sprocket 6 11 and the two sprockets 10 are connected by a chain 3 12;

[0040] A plurality of plow blades 30 are fixedly welded to one side of the bottom of the box body 1 through a crossbeam, a pulling frame 31 is fixedly welded to one side of the box body 1 at the position of the plow blades 30, and a group of support wheels 32 are fixedly installed on the other side of the box body 1 through a group of legs.

[0041] (I) The working principle of the conveyor chain structure of this bulbous medicinal material harvesting device is:

[0042] First, connect the pulling frame 31 to the traction part of the tractor, and connect the power output shaft of the tractor to the drive shaft access end 2601. At this time, the tractor can drag the device while transmitting the driving force to the steering gear 1 26. Then, through the connection of the transmission shaft 28, the rotating shaft 5 24 and the rotating shaft 6 25 can be driven to rotate at the same time (the specific connection and transmission principle between the steering gear and the shaft are already known public technologies, so they will not be described in detail here). When the rotating shaft 5 24 and the rotating shaft 6 25 rotate at the same time, the connection between the sprocket 2, the sprocket 3 17 and the chain 1 18 on the two conveying chain structures 13 is used. The corresponding conveying sprockets 15 on the two conveying chain structures 13 can be driven to rotate respectively, thereby prompting the conveying chain belt 16 to rotate, so as to facilitate the soil plowed by the plow blade 30 and the fruits of the bulbous medicinal materials and the corresponding fine rhizomes to be smoothly conveyed to the conveying chain belt 16 of the first conveying chain structure 13, and then to the guide inclined mesh plate 3 of the soil poking structure 2, and finally to the conveying chain belt 16 of the next conveying chain structure 13. In the process of conveying, the soil is constantly loosened and falls, and finally only the fruits of the bulbous medicinal materials and the corresponding fine rhizomes fall down through the end of the conveying chain belt 16 of the next conveying chain structure 13, so as to facilitate the workers to pick up;

[0043] During the process of conveying the above-mentioned soil mixed with the fruits of bulbous medicinal materials and the corresponding fine rhizomes on the two conveyor chain structures 13, since sprocket two and sprocket five 21 are coaxially installed, the driving force on chain one 18 can drive sprocket five 21 to rotate, and then drive sprocket four 20 and rotating shaft four 19 to rotate simultaneously through the connection of chain two 22, and finally drive a group of elliptical wheels 23 on rotating shaft four 19 to rotate simultaneously, continuously knocking the conveyor chain belt 16, causing the conveyor chain belt 16 to vibrate, thereby accelerating the shedding of the soil.

[0044] Embodiment 2:

[0045] In view of the above embodiment 1, for further description, refer to Figure 1-Figure 6 The soil poking structure 2 includes a guide inclined mesh plate 3, two swing arm structures 4 with the same structure are arranged at the bottom of the guide inclined mesh plate 3, and the swing arm structure 4 includes a plurality of arc arms 5 with the same structure, and the middle position of the plurality of arc arms 5 is fixedly welded by a rotating shaft 6, and both ends of the rotating shaft 6 are rotatably connected with a shaft seat 1, and the two shaft seats 1 are respectively fixedly installed on both sides of the inner wall of the box body 1, and the top of one end of the plurality of arc arms 5 is fixedly welded with a contact piece 501, and an avoidance opening 301 is opened on the guide inclined mesh plate 3 at the position corresponding to the contact piece 501, and the other ends of the plurality of arc arms 5 are fixedly welded by a connecting rod 7;

[0046] A strip-shaped travel hole 502 is also provided on the other end of the plurality of arc-shaped arms 5, and a shaft seat 2 is fixedly installed on one side of the inner wall of the box body 1, and a rotating shaft 2 8 is rotatably connected inside the shaft seat 2, and both ends of the rotating shaft 2 8 respectively penetrate into the inside of the box body 1 and the outside of the box body 1, and a rotating disk 9 is fixedly installed on the end of the rotating shaft 2 8 located inside the box body 1, and a connecting pile 901 is eccentrically fixedly welded on the rotating disk 9, and the connecting pile 901 is in contact with the inside of the corresponding strip-shaped travel hole 502, and a sprocket 10 is fixedly installed on the end of the rotating shaft 2 8 located outside the box body 1;

[0047] The guide inclined mesh plate 3 is fixedly welded inside the box body 1 at an inclined angle, and a transition plate 29 is fixedly welded on the top end of the guide inclined mesh plate 3, and the top end of the transition plate 29 does not contact the top of the conveyor chain belt 16.

[0048] (II) The working principle of the soil poking structure of the bulbous medicinal material harvesting device is:

[0049] Based on the above, when the rotating shaft 6 25 rotates, the sprocket 6 11 of the soil poking structure 2 can be driven to rotate, and then the sprocket 10 of the two swing arm structures 4 can be driven to rotate simultaneously through the connection of the chain 3 12. At this time, the rotation of the rotating disk 9 can be driven by the connection of the rotating shaft 2 8, and then the connection of the connecting pile 901, the bar travel hole 502 and the connecting rod 7 can respectively drive the several arc arms 5 on the two swing arm structures 4 to reciprocate, so as to realize the up and down movement of the contact piece 501 inside the avoidance opening 301, and the soil and fruit root and stem inclusions output from the end of the first conveying chain structure 13 are patted and poked, so as to accelerate the separation efficiency of the soil and fruit root and stem inclusions when they flow on the guide inclined mesh plate 3, and the separated soil can directly fall vertically through the mesh holes on the guide inclined mesh plate 3, and part of the soil and fruit root and stem inclusions continue to slide downward and enter the next conveying chain structure 13 for separation;

[0050] The transition plate 29 fixedly welded on the top end of the guide inclined mesh plate 3 serves to connect the end of the first conveying chain structure 13 with the top of the guide inclined mesh plate 3, which can prevent the soil and fruit rhizomes from falling directly due to the large gap, and can also prevent the reciprocating deflection of the arc arm 5 from interfering with the conveying chain belt 16 of the first conveying chain structure 13. In the actual manufacturing process, the inclination angle of the guide inclined mesh plate 3 of the soil-piercing structure 2 should be maintained between 50-70 degrees and welded to the inner wall of the box body 1 to prevent the soil and fruit rhizomes from failing to slide down smoothly due to the small slope of the guide inclined mesh plate 3.

[0051] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
