Description

Technical Field

[0001] The invention relates to the technical field of digging deep-rooted Chinese medicinal materials, in particular to a digging device for deep-rooted Chinese medicinal materials. Background Art

[0002] Burdock is an underground deep-rooted crop with long, stick-shaped rhizomes that penetrate vertically into the soil. At present, the mechanization level of burdock harvesting in my country is low, and most of them are done manually. The labor intensity and difficulty of digging and harvesting are very high, which is time-consuming and labor-intensive, and the production efficiency is extremely low. It is also easy to damage or break the rhizomes of burdock. When mechanical harvesting is adopted, the driving group drives two inclined plowshares to vibrate up and down, thereby "lifting" the soil and burdock upward to transport the burdock upward; In actual use, when the plowshares vibrate up and down to lift the burdock, the lifting force is often insufficient, because the burdock is located between the two plowshares, and the size of the lifting force is related to the spacing between the bottom ends of the plowshares and the misalignment angle between the upper and lower ends of the plowshares, that is, the smaller the spacing between the bottom ends of the plowshares (or the larger the misalignment spacing between the bottom and the top), the greater the lifting force when rising, but the spacing between the plowshares is generally fixed. Although there are types that can adjust the spacing, if the spacing between the plowshares is too small, it is easy to interfere with the burdock during movement. If it is too large, it is easy to cause insufficient lifting force, which makes the burdock able to be smoothly transported upward when the plowshares vibrate up and down to lift the burdock.

[0003] Based on this, the present invention designs a digging device for deep-rooted Chinese medicinal materials to solve the above problems. Summary of the invention

[0015] See also Figure 1-9 The present invention provides a technical solution: an excavation device for deep-rooted and stem-type Chinese medicinal materials, comprising a bracket 1, two main plowshares 2 fixed on the left and right sides of the bracket 1, and two auxiliary plowshares 3 located below the bracket 1, the bracket 1 is provided with a driving group, the bottom of the bracket 1 is slidably connected to a support frame 4, the two auxiliary plowshares 3 are respectively fixedly connected to the left and right sides of the bottom of the support frame 4, the support frame 4 is slidably connected to a driving plate 5, the driving group is used to drive the driving plate 5 to vibrate up and down, the driving plate 5 is slidably connected to push rods 6 on both sides, the auxiliary plowshares 3 are provided with slide grooves 7, the push rods 6 are respectively located in the two slide grooves 7, the side walls of the slide grooves 7 are rotatably connected to side plates 8, the bottom ends of the two push rods 6 are rotatably connected to support rods 9, and the top ends of the two support rods 9 are rotatably connected to the side plates 8.

[0016] like Figure 1-Figure 6 As shown: The support 1 is connected to the tractor and driven forward by the tractor. The support 1 is raised and lowered by the hydraulic group at the rear end of the tractor. When harvesting burdock, the support 1 is lowered and moves with the tractor, so that the main coulter 2 and the auxiliary coulter 3 enter the ground together to break the soil. In the process of breaking the soil, the driving plate 5 is moved up and down by the driving group. The process of driving board 5 rising: When the driving plate 5 rises, the push rod 6 is driven to slide up from the inside of the slide groove 7. At this time, the push rod 6 will maintain the upward trend and slide to the left and right sides along the end of the driving plate 5. When the push rod 6 rises, it will push the side plates 8 to gradually expand inside the slide groove 7 through the support rod 9. At this time, the soil and burdock in the middle of the side plates 8 will be squeezed on both sides, so that the soil can hold the burdock tightly. After the bottom end of the push rod 6 contacts the side wall of the slide groove 7, the push rod 6 will directly pull the auxiliary plowshare 3 and the support frame 4 to rise together with the driving plate 5. At this time The support frame 4 slides up along the bracket 1, and the auxiliary plowshare 3 and the side plate 8 will "lift" the burdock and the soil around it at the same time, and the side plate 8 can squeeze the soil on both sides of the burdock while increasing the lifting force, thereby preventing the soil on both sides of the burdock from being loosened, causing insufficient force when the burdock is transported upward or the burdock to tilt directly, and, in this way, the distance between the two auxiliary plowshares 3 does not need to be adjusted, so that too small a distance will interfere with the burdock, and too large a distance will cause insufficient lifting force; When the driving plate 5 rises to the highest point, the burdock will be transported to the upper layer of the soil and can be picked out manually, and then the driving plate 5 starts to descend; The process of driving plate 5 descending: When the driving plate 5 descends, the supporting frame 4 is driven to slide down along the bracket 1. At this time, the push rod 6 slides downward along the slide groove 7. At this time, the push rod 6 moves along the end of the driving plate 5 toward the driving plate 5, and the side plate 8 is gradually pulled together by the support rod 9 until the push rod 6 and the auxiliary plow 3 descend to the initial position and the next lifting work can be carried out; The burdock harvesting work is completed by repeatedly rising and falling the auxiliary plowshare 3 and repeatedly unfolding and retracting the side plates 8.

[0017] Two first positioning holes 10 and second positioning holes 11 are provided on the left and right sides of the driving plate 5. The second positioning hole 11 is located below the first positioning hole 10. A positioning rod 12 is provided inside the first positioning hole 10. The positioning rod 12 is slidably connected to the side wall of the support frame 4. A first spring 13 is fixedly connected between the side wall of the positioning rod 12 and the inner wall of the support frame 4. A contact rod 14 is provided on the side wall of the positioning rod 12. A wedge block 15 is provided below one side of the contact rod 14. The wedge block 15 is used to push the contact rod 14 to drive the positioning rod 12 to slide.

[0018] The contact rod 14 is rotatably connected to the positioning rod 12 .

[0019] like Figure 2 , Figure 3 as well as Figure 7 As shown: When the driving plate 5 does not rise, the positioning rod 12 is inside the first positioning hole 10. At this time, the positioning rod 12 will restrict the support frame 4 by plugging into the first positioning hole 10, so as to prevent the support frame 4 and the auxiliary plowshare 3 from rising in the early stage of the rising of the driving plate 5. When the driving plate 5 rises: The driving plate 5 will slide up along the supporting frame 4, and the wedge block 15 will approach the positioning rod 12 from below. At this time, the push rod 6 will slide up from the inside of the slide groove 7 and slide along the driving plate 5. At this time, the support rod 9 will push the side plate 8 to unfold. After the side plate 8 is unfolded, the wedge block 15 will rise to a height higher than the positioning rod 12. In the process of the wedge block 15 rising to a height higher than the positioning rod 12, the side wall of the wedge block 15 will contact the contact rod 14. At this time, the contact rod 14 will rotate and drive the positioning rod 12 along the driven wedge block 15. The bracket 1 slides and compresses the first spring 13, at which time the positioning rod 12 will move out from the inside of the first positioning hole 10, and the positioning rod 12 will release the restriction on the support frame 4, and then the push rod 6 will unfold the side plate 8 through the support rod 9, and at this time the push rod 6 will drive the auxiliary coulter 3 and the support frame 4 to rise together, and at this time the wedge block 15 will pass over the positioning rod 12, and at this time the positioning rod 12 will contact the side wall of the support frame 4 under the reset action of the first spring 13, and at this time the auxiliary coulter 3 and the side plate 8 will keep the soil and burdock lifted and transported upward during the rising process; After the driving plate 5 rises to the highest point, the positioning rod 12 will enter the second positioning hole 11, and the downward trend of the support frame 4 and the auxiliary plow 3 will be stopped, and the driving plate 5 will descend; When the driving plate 5 descends: At this time, the wedge block 15 will descend, the push rod 6 will slide down along the slide groove 7 and close the side plate 8 through the support rod 9. After the side plate 8 is completely closed, the wedge block 15 will contact the contact rod 14 during the descent process, and then drive the positioning rod 12 to move out of the second positioning hole 11 through the contact rod 14, and then the support frame 4 and the auxiliary coulter 3 will descend until they are lowered to the limit and the positioning rod 12 enters the first positioning hole 10. That is, through the cooperation of the wedge block 15, the positioning rod 12, the contact rod 14 and the first spring 13, when the driving plate 5 rises, the side plate 8 will first unfold to complete the pre-lifting of the soil and burdock, so that the burdock and the soil can be tightly embraced, thereby increasing the force of the auxiliary plowshare 3 when it rises, and then the auxiliary plowshare 3 can rise. When the driving plate 5 descends, the burdock has been transported to the ground. At this time, the side plate 8 will first be retracted. After the retraction is completed, the auxiliary plowshare 3 can be lowered only after the restriction on the support frame 4 and the auxiliary plowshare 3 is released. In this way, it can be avoided that the side plate 8 is blocked by the soil when the auxiliary plowshare 3 and the unfolded side plate 8 descend together.

[0020] Two wedge-shaped support blocks 16 are fixedly connected to the auxiliary plowshares 3, the bottom ends of the side plates 8 are rotatably connected to baffles 17, the bottom ends of the baffles 17 are rotatably connected to slide bars 18, and the slide bars 18 are slidably connected to the two auxiliary plowshares 3 respectively.

[0021] like Figure 4-Figure 6 As shown: When the side panel 8 is pushed and unfolded by the support rod 9, the side wall of the side panel 8 will contact the support block 16, and the support block 16 can prevent soil from entering the inside of the side panel 8 and the chute 7. When the side panel 8 is unfolded, the baffle 17 will rotate with the side panel 8 and its bottom end will rotate on the slide bar 18 while pulling the slide bar 18 to slide along the auxiliary plow blade 3, and the side wall of the baffle 17 is also in contact with the support block 16, thereby preventing the formation of gaps to enter the soil.

[0022] A second spring 19 is fixedly connected between the left and right side walls of the push rod 6 and the driving plate 5 .

[0023] Rollers 20 are disposed above and below the end of the driving plate 5 , and the rollers 20 are rotatably connected to the inner wall of the push rod 6 .

[0024] like Figure 8 and Fig. 9 As shown: When the driving plate 5 is raised or lowered, the push rod 6 slides up and down inside the slide groove 7. At this time, the push rod 6 will slide along the recessed position at the end of the driving plate 5 through the roller 20, thereby reducing the friction force. The compression and relaxation of the second spring 19 can reset the push rod 6.

[0025] The driving group includes a crankshaft 21 and a support shaft 22 , wherein the support shaft 22 is rotatably connected to the top of the driving plate 5 , the support shaft 22 is rotatably connected to the crankshaft 21 , the crankshaft 21 is fixedly connected to a driving motor 23 , and the driving motor 23 is fixedly connected to the bracket 1 .

[0026] like Figure 2 and Figure 7 As shown: When the driving motor 23 is working, it drives the crankshaft 21 to rotate, and then drives the driving plate 5 to move up and down through the crankshaft 21 and the support shaft 22. The lifting method of the driving plate 5 can also be various in the prior art.
