Abstract
Description
Technical Field
[0001] This application relates to the field of tea tree planting technology, and in particular to a tea tree planting device for tea oil production. Background Technology
[0002] Camellia oleifera is a high-quality edible oil plant unique to China. Its seeds can be pressed to extract tea oil. Nowadays, tea tree planting equipment is usually used to plant camellia oleifera seedlings, so that camellia oleifera can maintain a better growth condition.
[0003] Some existing tea tree planting equipment mainly consists of a lifting mechanism, a digging mechanism, and a filling mechanism. In use, the lifting mechanism drives the digging and filling mechanisms to move downwards, allowing the digging mechanism to gradually penetrate the soil layer and transfer the soil from the soil layer to the filling mechanism. When the digging mechanism has penetrated to a certain depth, the lifting mechanism drives the digging and filling mechanisms to move upwards and reset, thus digging a tree hole in the soil layer. Then, the filling mechanism uses a mixing component to break up the soil that has entered the hole, and the broken soil falls next to the tree hole. Finally, the seedling is planted in the tree hole, and the broken soil is backfilled into the tree hole. Through the above actions, the planting operation of the tea tree seedling is completed.
[0004] However, during the above process, when the soil excavated by the hole-digging mechanism is moist soil, the mixing component in the backfilling mechanism will not break up the moist soil. Instead, it will cause the moist soil to stick together, resulting in larger soil clods when backfilling, which will affect the growth of the seedlings and the development of their roots. Summary of the Invention
[0005] This application proposes a tea tree planting device for tea oil production, which has the advantage of reducing the volume of moist backfill soil blocks, thereby solving the problem that the large volume of moist backfill soil blocks affects the growth of seedlings and the development of root systems.
[0006] To achieve the above objectives, this application adopts the following technical solution: a tea tree planting device for tea oil production, comprising:
[0007] A cylindrical body, wherein a fixing member is fixed at the upper part of one side of the cylindrical body, and a lifting mechanism is provided above the fixing member, and the output end of the lifting mechanism is fixedly connected to the fixing member;
[0008] A auger for digging holes is rotatably installed in the inner cavity of the cylinder. Both the upper and lower ends of the auger extend from the corresponding directions of the cylinder. The lower end of the cylinder is open. A power mechanism is fixedly installed at the center of the upper side of the cylinder. The output shaft of the power mechanism is fixedly connected to the upper end of the auger.
[0009] An excavation pipe is fixedly installed at the upper part of the other side of the cylinder. One end of the excavation pipe facing the cylinder is connected to the upper part of the inner cavity of the cylinder, and the other end of the excavation pipe is connected to the external environment.
[0010] A cutting rod is fixedly installed at the other end of the soil outlet pipe to cut the soil.
[0011] The striking mechanism, located on the upper side of the cylinder, is used to impact the soil discharged from the discharge pipe.
[0012] Furthermore, the striking mechanism includes a second power mechanism, a rotating shaft, and a striking rod. The second power mechanism is fixedly installed on the upper side of the cylinder. A rotating shaft is provided on the side of the second power mechanism facing the soil discharge pipe. One end of the rotating shaft is fixedly connected to the output shaft of the second power mechanism. A striking rod is fixedly fixed circumferentially at the other end of the rotating shaft. The striking rod forms a sliding contact with the port of the soil discharge pipe facing away from the cylinder.
[0013] Furthermore, the cutting rods are arranged horizontally and longitudinally at intervals to increase the number of mud strips in the soil discharge pipe.
[0014] Furthermore, the striking rod is designed as a cuboid to reduce the contact area between the striking rod and the mud.
[0015] Furthermore, the rotational speed of the shaft is greater than that of the auger, which is used to increase the number of contacts between the striking rod and the mud strip per unit time.
[0016] Furthermore, a baffle plate is provided on the front side of the cylinder and the front side of the striking rod, and a connecting rod is fixedly installed between the cylinder and the baffle plate. The height of the upper side of the baffle plate is greater than the height of the striking rod.
[0017] Furthermore, a fertilizer box is fixedly installed on the upper side of the baffle plate and at the position corresponding to the striking rod, and a discharge port is fixedly installed at the lower end of the fertilizer box, with the discharge port located between the baffle plate and the striking rod.
[0018] Furthermore, the discharge port and the side of the baffle plate facing the striking rod form a smooth transition connection.
[0019] Furthermore, the side of the baffle plate facing the striking rod gradually tilts towards the cylinder from top to bottom.
[0020] Furthermore, the side of the baffle plate facing the striking rod has a movable groove, and a movable plate is movably installed in the movable groove. The upper part of the movable plate facing away from the striking rod is rotatably connected to the side wall of the movable groove facing the striking rod. An extension rod is fixedly installed in the middle of the side of the movable plate facing away from the striking rod. The other end of the extension rod passes through the baffle plate. A first elastic element is sleeved on the outer side of the end of the extension rod that passes through the baffle plate. The first elastic element is fixedly connected to the end of the extension rod that passes through the baffle plate and the baffle plate. An installation component is fixedly installed on the side of the discharge port facing the striking rod. A sliding plate is movably installed inside the installation component and inside the discharge port. A second elastic element is provided inside the installation component and on the side of the sliding plate facing the striking rod. The two ends of the second elastic element are respectively fixedly connected to the side of the sliding plate facing the striking rod and the inner wall of the installation component. A pull rope is fixedly installed on the upper end of the movable plate. The other end of the pull rope passes through the baffle plate, the fertilizer box, and the discharge port, and is fixedly connected to the side of the sliding plate facing away from the striking rod.
[0021] This application has the following beneficial effects:
[0022] This application provides a tea tree planting device for tea oil production. By setting up a cutting rod and a striking rod, the cutting rod cuts the moist soil discharged from the soil outlet pipe into several mud strips. Then, the striking rod quickly contacts the mud strips, thereby breaking the mud strips into small pieces and falling to one side of the device. Through the above actions, the volume of the moist backfill soil is reduced, so that the growth of the seedlings and the development of the root system are less affected.
[0023] By setting up the slapping rod and the baffle plate, during the process of the slapping rod splitting the mud strips, the mud blocks that are split off will be thrown out by the slapping rod. Then, the thrown mud blocks will be blocked by the baffle plate and slide down the surface of the baffle plate. Through the above actions, the throwing distance of the mud blocks is limited, so that the mud blocks are kept at a closer distance to the tree pits dug later, which facilitates the backfilling of the soil.
[0024] By setting up a tamping bar, a baffle plate, and a fertilizer box, while the baffle plate restricts the distance the mud blocks are thrown, the fertilizer box simultaneously delivers dry powdered fertilizer to the surface of the baffle plate, causing the thrown mud blocks to come into contact with and mix with the fertilizer. This action improves the utilization efficiency of the fertilizer. At the same time, since the fertilizer is between the baffle plate and the mud blocks, the probability of the mud blocks sticking to the baffle plate is reduced, making the amount of backfill soil less affected.

[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0038] Example 1
[0039] Please see Figure 1 and Figure 2A tea tree planting device for tea oil production includes a cylinder 1. A fixing member 2 is welded and fixed to the upper part of one side of the cylinder 1. A lifting mechanism 3 (such as a hydraulic telescopic rod) is installed above the fixing member 2. The output end of the lifting mechanism 3 is fixedly connected to the fixing member 2. The lower end of the cylinder 1 is open. A hole-digging auger 4 is rotatably installed in the inner cavity of the cylinder 1. Both the upper and lower ends of the hole-digging auger 4 extend from the corresponding directions of the cylinder 1. A first power mechanism 5 (such as a motor) is fixedly installed at the center of the upper side of the cylinder 1. The output shaft of the first power mechanism 5 is fixedly connected to the upper end of the hole-digging auger 4. A soil-exiting pipe 6 is fixedly installed at the upper part of the other side of the cylinder 1. One end of the excavation pipe 6 facing the cylinder 1 is connected to the upper part of the inner cavity of the cylinder 1, and the other end of the excavation pipe 6 is connected to the external environment. A cutting rod 7 is fixedly installed at the other end of the excavation pipe 6. A second power mechanism 8 (such as a motor) is fixedly installed on the upper side of the cylinder 1 and on the side of the first power mechanism 5 facing away from the lifting mechanism 3. A rotating shaft 9 is provided on the side of the second power mechanism 8 facing the excavation pipe 6. One end of the rotating shaft 9 is fixedly connected to the output shaft of the second power mechanism 8. A striking rod 10 is welded circumferentially at equal intervals to the other end of the rotating shaft 9. The striking rod 10 forms a sliding contact with the end of the excavation pipe 6 facing away from the cylinder 1. The striking rod 10 is cylindrical.
[0040] In operation, the first power mechanism 5 drives the digging auger 4 to rotate, and the second power mechanism 8 drives the rotating shaft 9 and the striking rod 10 to rotate. Then, the lifting mechanism 3, through the fixing component 2, drives the digging auger 4 and the cylinder 1 to move downwards, causing them to gradually extend into the soil layer. The soil in the soil layer is driven by the digging auger 4 and moves upwards within the cylinder 1. The upward-moving soil is then squeezed into the discharge pipe 6 and discharged into the external environment. During this process, when the soil discharged from the discharge pipe 6 is dry (such as surface soil), the dry soil first contacts the cutting rod 7. Due to the push from subsequent soil, it then makes hard contact with the cutting rod 7, further reducing the volume of the soil after it is discharged from the discharge pipe 6. Then, the discharged soil contacts the rotating striking rod 10 and is further struck into smaller pieces. Small clods of soil are reduced in volume through the above actions. When the soil discharged from the soil outlet pipe 6 is in a moist state (such as soil deep in the soil layer), the moist soil is cut into several strips by the cutting rod 7. Then, the strips are discharged from the soil outlet pipe 6 and come into contact with the striking rod 10, which further divides the strips into small pieces and falls to one side of the device. Through the above actions, the volume of the moist backfill clods is reduced, so that the growth of the seedlings and the development of the root system are not easily affected. When the digging auger 4 and the cylinder 1 are inserted to a certain depth, the lifting mechanism 3 drives the digging auger 4 and the cylinder 1 to move upward and reset, so that the tree pit is dug out in the soil layer. After that, when the soil in the cylinder 1 is emptied, the above structure stops operating. Then, the seedling is planted into the tree pit, and the soil that was originally dug out is backfilled into the tree pit. Through the above actions, the planting operation of the camellia seedling is completed.
[0041] Please see Figure 2 The cutting rod 7 is set horizontally. This setting makes it so that when the striking rod 10 separates the wet mud strips, the mud pieces that are cut off are not easily moved by the striking force applied by the striking rod 10, so that the cut mud pieces are not easily stuck together again.
[0042] Please see Figure 3 The cutting rods 7 are arranged longitudinally at intervals, which increases the number of mud strips formed by the moist soil, and thus increases the number of mud blocks that are subsequently cut off. Since the amount of soil removed remains the same, but the number of mud blocks increases, the volume of each mud block is further reduced, so that the growth of the seedlings and the development of the root system are less affected.
[0043] Please see Figure 4 The striking rod 10 is designed as a cuboid, which reduces the contact area between the striking rod 10 and the mud block, making it less likely for the wet mud block to stick to the striking rod 10.
[0044] The rotational speed of the shaft 9 is greater than that of the auger 4, which increases the number of times the striking rod 10 contacts the mud strip per unit time, thereby further reducing the volume of the wet mud block.
[0045] Example 2
[0046] Please see Figures 1-5 This embodiment is a further improvement of Embodiment 1. The improvement is that a baffle plate 11 is provided on the front side of the cylinder 1 and the front side of the striking rod 10. A connecting rod 12 is fixedly installed between the cylinder 1 and the baffle plate 11. The height of the upper side of the baffle plate 11 is greater than the height of the striking rod 10.
[0047] During the process of the striking rod 10 splitting the mud strips, the split mud blocks are thrown out by the striking rod 10. Then, the thrown mud blocks are blocked by the baffle plate 11 and slide down the surface of the baffle plate 11. Through the above actions, the throwing distance of the mud blocks is limited, so that the mud blocks are kept closer to the tree pits dug later, which facilitates the backfilling of the soil. At the same time, when the dry soil comes into contact with the baffle plate 11, the impact force between the two will cause the dry soil to be further broken, thereby further reducing the volume of the backfill soil.
[0048] Example 3
[0049] Please see Figures 1-6 This embodiment is a further improvement of embodiment two. The improvement is that a fertilizer box 13 is fixedly installed on the upper side of the baffle plate 11 and at the position corresponding to the striking rod 10. The lower end of the fertilizer box 13 is connected to and fixedly installed with a discharge port 14. The discharge port 14 is located between the baffle plate 11 and the striking rod 10. The discharge port 14 and the side of the baffle plate 11 facing the striking rod 10 form a smooth transition connection.
[0050] During the process of limiting the throwing distance of mud blocks by the aforementioned baffle plate 11, dry powdered fertilizer is added to the fertilizer box 13, so that the fertilizer falls onto the surface of the baffle plate 11 through the discharge port 14 and slides down the surface. During this process, the thrown mud blocks will come into contact with and mix with the sliding fertilizer, thereby improving the utilization efficiency of the fertilizer. At the same time, since the fertilizer is between the baffle plate 11 and the mud blocks, the probability of the mud blocks sticking to the baffle plate 11 is reduced, so that the amount of backfill soil is not easily affected.
[0051] Please see Figure 6 The side of the baffle plate 11 facing the striking rod 10 gradually tilts from top to bottom toward the cylinder 1.
[0052] The above settings increase the contact between the fertilizer and the surface of the baffle plate 11, thereby slowing down the downward speed of the fertilizer and promoting full contact and mixing between the fertilizer and the mud.
[0053] Example 4
[0054] Please see Figures 1-9This embodiment is a further improvement on embodiment three. The improvement lies in that: a movable groove is formed on the side of the blocking plate 11 facing the striking rod 10, and a movable plate 15 is slidably installed in the movable groove. The upper part of the movable plate 15 facing away from the striking rod 10 is rotatably connected to the side wall of the movable groove facing the striking rod 10. An extension rod 16 is fixedly installed at the middle part of the movable plate 15 facing away from the striking rod 10. The other end of the extension rod 16 passes through the blocking plate 11. A first elastic element 17 is sleeved on the outer side of one end of the extension rod 16 passing through the blocking plate 11. One end of the first elastic element 17 is fixedly connected to the end of the extension rod 16 passing through the blocking plate 11, and the other end of the first elastic element 17 is fixedly connected to the end of the extension rod 16 passing through the blocking plate 11. Plate 11 is fixedly connected. An installation part 18 is fixedly installed on the side of the discharge port 14 facing the striking rod 10. A sliding plate 19 is slidably installed inside the installation part 18 and the discharge port 14. The side of the sliding plate 19 facing away from the striking rod 10 is inclined downward. A second elastic element 20 is provided inside the installation part 18 and on the side of the sliding plate 19 facing the striking rod 10. The two ends of the second elastic element 20 are fixedly connected to the side of the sliding plate 19 facing the striking rod 10 and the inner wall of the installation part 18, respectively. A pull rope 21 is fixedly installed on the upper end of the movable plate 15. The other end of the pull rope 21 passes through the baffle plate 11, the fertilizer box 13, and the discharge port 14, and is fixedly connected to the side of the sliding plate 19 facing away from the striking rod 10.
[0055] During the excavation process of the aforementioned auger 4, the surface soil is first discharged from the outlet pipe 6. This soil is in a dry state. As this dry soil passes through the auger 4, the cutting rod 7, and the striking rod 10, it is broken into small particles. Then, the soil from deeper layers is discharged from the outlet pipe 6. This soil is in a moist state. Although this soil is separated into small mud blocks by the cutting rod 7 and the striking rod 10, the mass of these small mud blocks is greater than the mass of the small particles. Then, as both are thrown towards the baffle plate 11, the impact force of the small mud blocks on the movable plate 15 is greater than the impact force of the small particles on the movable plate 15. This causes the movable plate 15 to deflect when the small mud blocks hit the movable plate 15, which in turn causes the extension rod 16 to stretch the first elastic element 17. The upper end of the plate 15 is driven by the pull rope 21 to drive the slide plate 19 to overcome the elastic force of the second elastic element 20, so that the slide plate 19 extends further into the discharge port 14, thereby reducing the amount of fertilizer discharged from the discharge port 14. Since the amount of fertilizer applied to each tree pit is fixed, the dry soil is mixed with more fertilizer, while the moist soil is mixed with less fertilizer. When the soil stops being discharged from the soil discharge pipe 6, the first elastic element 17 and the second elastic element 20 drive the corresponding structure to reset. At this time, the fertilizer in the fertilizer box 13 has also been emptied. Afterwards, during the subsequent backfilling operation, since the dry soil is at the bottom and the moist soil is above the dry soil, after the soil is finally backfilled into the tree pit (the soil pile is pushed into the tree pit), the dry soil mixed with more fertilizer is closest to the tree roots, thereby maximizing the utilization efficiency of fertilizer.
