Description

Technical Field

[0001] This invention belongs to the technical field of seedling transplantation, specifically relating to a vegetable seedling transplanting device for use in vegetable greenhouses. Background Technology

[0002] Transplanting is a cultivation method in which crops are raised in seedbeds and then transplanted to the field. Transplanting technology is also used in vegetable greenhouses. Due to the lack of space and electricity, large-scale mechanized use is not suitable for greenhouses. The most common transplanting device is a handheld transplanter (which has two functions: picking up seedlings and planting seedlings). It consists of an open cylinder, a handle, a connecting rod, and a ground-drilling plate. When operating, simply pull the handle to open the ground-drilling plate, drive the plate into the ground, close the plate, and pull the handle to pick up the vegetable seedling. When you need to plant the vegetable seedling in the field, simply reverse the operation.

[0003] Existing handheld transplanters have a fixed opening angle due to the fixed size of the drilling plate, which limits the range of vegetable seedlings that can be harvested. Furthermore, they can only drill holes of a single diameter during planting and cannot be adjusted according to different types of vegetables, thus restricting their application. Although it is possible to purchase handheld transplanters of different sizes, this undoubtedly increases equipment and management costs. Summary of the Invention

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Example 1

[0029] Reference Figure 1 - Figure 6 This is the first embodiment of the present invention. This embodiment provides a vegetable seedling transplanting device for vegetable greenhouses, which realizes the effect of adjusting the size of the drill plate 11 to improve the applicability of the seedling transplanting device. It includes an adjustment mechanism, including a cylinder 10. Two semi-circular drill plates 11 are provided on the lower side of the cylinder 10. A T-shaped plate 12 is fixedly connected to the lower end of the cylinder 10 through a connecting block. A strip groove 13 is provided on the T-shaped plate 12. A strip block 14 is provided on the drill plate 11. The strip block 14 slides in the strip groove 13 to adjust the distance between the two drill plates 11. A limiting component 15 is provided on the strip block 14 to prevent the drill plate 11 from loosening after displacement. A ring 16 is slidably connected to the cylinder 10. A power component 17 and a connecting component 18 are provided on the ring 16 to provide power for opening the drill plate 11. A horizontal plate is fixedly connected to the drill plate 11. A pressing component 19 is provided on the horizontal plate to prevent jamming when adjusting the drill plate 11.

[0030] The replacement mechanism includes a mounting slot 20 disposed within the drilling plate 11, a sliding assembly 21 that automatically fills the gap after the drilling plate 11 is separated, a wire guide groove 22 on the horizontal plate, a pulling assembly 23 that provides the necessary power to the sliding assembly 21 within the wire guide groove 22, and a T-shaped guide groove 24 on the horizontal plate, a T-shaped block 25 slidably connected within the guide groove 24, and a transmission assembly 26 that provides the necessary power to the pulling assembly 23 on the T-block 25.

[0031] Both drilling plates 11 have notches to prevent them from getting stuck during rotation. After the two drilling plates 11 separate, their bottoms cannot close properly, requiring replacement to ensure the bottom of the drilling plate 11 is sealed and the root can be cut. The horizontal plate and T-shaped plate 12 are made of metal and will not move underground during use.

[0032] Furthermore, the limiting component 15 includes a fixing block 151 fixedly connected to the drilling plate 11. The fixing block 151 has a circular opening 152 extending into the drilling plate 11. The circular opening 152 has multiple anti-detachment grooves 153. Anti-detachment blocks 154 are slidably connected in each of the multiple anti-detachment grooves 153. A cylinder 155 is fixedly connected to the anti-detachment block 154. A threaded rod 156 is rotatably connected in the circular opening 152. The cylinder 155 has a threaded hole that mates with the threaded rod 156. The strip groove 13 has multiple support openings 157 for the cylinder 155 to rotate. The diameter of the support opening 157 is larger than the width of the strip groove 13. The cylinder 155 is fixedly connected to the strip block 14. The strip block 14 is located at the front end of the cylinder 155.

[0033] In this case, the diameter of the support opening 157 is larger than the width of the strip groove 13, so that when the cylinder 155 is engaged with the support opening 157, the cylinder 155 will not move into the strip groove 13, ensuring that the cylinder 155 can rotate within the support opening 157. The outer end of the anti-detachment block 154 does not protrude outside the circular opening 152, thus not blocking the cylinder 155 from rotating within the support opening 157. In addition, the length of the strip groove 13 is greater than the movement distance of the cylinder 155, ensuring that the cylinder 155 can always be guided.

[0034] Preferably, the power assembly 17 includes a fixed post 171 fixedly connected to the cylinder 10, a mounting base fixedly connected to the cylinder 10, a handle 172 rotatably connected to the mounting base, a first bearing block 173 fixedly connected to the handle 172, and a second bearing block 174 fixedly connected to the cylinder 10. Both the first bearing block 173 and the second bearing block 174 are provided with first mounting holes, which are connected by a tension spring 175. The ring 16 is provided with two L-shaped first connecting rods 176, and the first bearing block 173 is provided with a mounting bracket for the first connecting rods 176. The second mounting hole is rotatable; the connecting assembly 18 includes multiple limiting ports 181 set on the horizontal plate, a second connecting rod 182 is provided on the ring 16, and a mounting cylinder 183 with an open rear end is fixedly connected to the second connecting rod 182. A push post 184 that cooperates with the multiple limiting ports 181 is slidably connected inside the mounting cylinder 183. The push post 184 is elastically connected to the inner wall of the mounting cylinder 183 through a first spring 185. The number of limiting ports 181 is the same as the number of support ports 157, and the distance between two adjacent support ports 157 is equal to the distance between two adjacent limiting ports 181.

[0035] It should be noted that an anti-slip sleeve is fixedly connected to the fixed column 171, which can play an anti-slip role. The first connecting rod 176 can rotate in the second mounting hole to prevent jamming. When the drilling plate 11 moves, the push column 184 at the rear end of the second connecting rod 182 cooperates with different limit ports 181 to adjust the drilling plate 11 without changing the length of the second connecting rod 182.

[0036] In use, when it is necessary to remove the seedling from the ground, simply press the handle 172, causing it to deflect towards the fixed post 171. This moves the first bearing block 173, which in turn moves the ring 16 upward via the first connecting rod 176. Simultaneously, the tension spring 175 is stretched. As the ring 16 moves upward, it drives the second connecting rod 182, which in turn moves the horizontal plate. This causes the cylinder 155 on the drilling plate 11 to rotate within the support opening 157, and the two drilling plates 11 unfold. At this point, the drilling plates 11 can be directly inserted into the ground, positioned on either side of the seedling. Release handle 172, and under the action of tension spring 175, handle 172 will return to its original position. Of course, handle 172 can also be pushed to ensure that handle 172 can return to its original position. When handle 172 returns to its original position, ring 16 returns to its original position, and the drilling plate 11 returns to its original position through transmission. At this time, the side wall of the drilling plate 11 cuts off the seedling roots. Then, pull up the fixing post 171 to take out the seedling. When planting, simply press the drilling plate 11 into the ground first, then open the drilling plate 11 to enlarge the hole, then put the seedling into the hole from the cylinder 10, and then take out the cylinder 10. The above operation is existing technology and will not be described in detail here.

[0037] When the drilling diameter of the drilling plate 11 needs to be adjusted, or when it is necessary to remove seedlings of different sizes, simply rotate the threaded rod 156. At this time, the cylinder 155 moves towards the circular opening 152, and the anti-detachment block 154 slides in the anti-detachment groove 153 for guidance. The movement of the cylinder 155 towards the circular opening 152 will cause the strip block 14 to move towards the circular opening 152. When the strip block 14 moves into the strip groove 13, it pushes the push column 184 to move away from the limiting port 181. At this time, the drilling plate 11 can be moved in the left and right directions to separate the two drilling plates 11, so that larger seedlings can be removed. After the adjustment is completed, make the cylinder 155 and the support port 157 face each other, and then reverse the threaded rod 156 so that the cylinder 155 and the support port 157 can cooperate to allow the subsequent rotation of the drilling plate 11. At the same time, make the push column 184 cooperate with the new limiting port 181 to complete the adjustment of the drilling plate 11.

[0038] In summary, by setting up an adjustment mechanism, when it is necessary to adjust the drilling diameter of the drilling plate 11 or to accommodate the removal of seedlings of different sizes, simply rotate the threaded rod 156 and push the push column 184 out of the limit port 181 to move the position of the drilling plate 11, thereby adapting to different needs. Example 2

[0039] Reference Figure 1 - Figure 6This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a pressing component 19 for a vegetable seedling transplanting device for a vegetable greenhouse, which solves the problem of how to push out the push column 184. It includes a movable plate 191 disposed on the rear side of the horizontal plate. A movable column 192 that cooperates with the limiting port 181 is fixedly connected to the movable plate 191. The horizontal plate is provided with a T-shaped inner groove 193. A T-shaped strip 194 that is fixed to the movable plate 191 is slidably connected in the inner groove 193. The T-shaped strip 194 is elastically connected to the inner wall of the inner groove 193 by a second spring.

[0040] Specifically, the moving distance of the movable column 192 is greater than the depth of the push column 184 extending into the limiting port 181, and the depth of the inner groove 193 is greater than the width of the horizontal side of the T-shaped strip 194. Thus, the T-shaped strip 194 can slide a certain distance in the inner groove 193 to push out the push column 184. Here, the outer end of the threaded rod 156 is provided with a handle to rotate the threaded rod 156.

[0041] When adjusting the drilling plate 11 during use, after rotating the threaded rod 156, press the moving plate 191, which will cause the moving column 192 to push the push column 184, allowing the push column 184 to leave the limit port 181. At this time, the drilling plate 11 can be pushed. Here, the T-shaped strip 194 cooperates with the inner groove 193 to guide the moving plate 191.

[0042] In summary, by setting up the pressing component 19, after rotating the threaded rod 156, pressing the moving plate 191 will cause the push column 184 to leave the limit port 181. At this time, the horizontal plate can be moved to adjust the drilling plate 11. Moreover, multiple push columns 184 are set on the moving plate 191. No matter which limit port 181 the push column 184 is in, the push column 184 can be pushed out. Example 3

[0043] Reference Figure 1 - Figure 6This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a substitute mechanism for a vegetable seedling transplanting device in a vegetable greenhouse. It solves the problem of ensuring that the lower ends of the two drilling plates 11 can cut off the seedling roots after adjusting the position of the drilling plates 11. It includes a sliding assembly 21, a support shaft fixedly connected in the mounting groove 20, a gear 211 rotatably connected to the support shaft, and a pair of toothed plates 212 slidably connected in the mounting groove 20 that mesh with the gear 211. The drilling plates 11 have an arc-shaped groove 213, and a substitute plate 214 is slidably connected in the arc-shaped groove 213. Both ends of the arc-shaped groove 213 penetrate the drilling plates 11, and the arc-shaped groove 213 communicates with the mounting groove 20 through a connection port. The toothed plate 212 on the inner sidewall of the drilling plate 11 is Z-shaped, and the Z-shaped toothed plate 212 passes through the connection port and is fixedly connected to the replacement plate 214; the pulling assembly 23 includes a steel wire rope 231 disposed in the wire guide groove 22, the steel wire rope 231 is fixedly connected to the toothed plate 212 near the outer sidewall of the drilling plate 11, the horizontal plate is provided with a horizontal opening 232 communicating with the wire guide groove 22, and a sliding plate 233 fixed to the end of the steel wire rope 231 is provided in the horizontal opening 232; the transmission assembly 26 includes a U-shaped plate 261 fixedly connected to the T-shaped plate 12, the sidewall of the U-shaped plate 261 abuts against the sidewall of the sliding plate 233, and a horizontal bar 262 is fixedly connected to one toothed plate 212, the horizontal bar 262 is elastically connected to the inner wall of the mounting groove 20 through a third spring 263.

[0044] Specifically, two toothed plates 212 are set at both ends of the gear 211, so that when the gear 211 rotates, the two toothed plates 212 move in opposite directions. The bottom of the substitute plate 214 is pointed, which facilitates drilling. The lower end of the toothed plate 212 connected to the substitute plate 214 has no teeth, so the connection port can fit with the lower end of the toothed plate 212, preventing soil from entering the mounting groove 20. Rollers can also be set in the wire groove 22 to facilitate the sliding of the wire rope 231. The crossbar 262 is damped between itself and the inner wall of the mounting groove 20. The side wall of the U-shaped plate 261 abuts against the side wall of the mounting cylinder 183, so that the U-shaped plate 261 is always on the inner side of the push column 184 (the side closer to the cylinder 155) and will not move to the outer side of the push column 184.

[0045] During use, when adjusting the drilling plate 11, the horizontal plate position will move. At this time, since the second connecting rod 182 does not move, the mounting cylinder 183 will not move. The U-shaped plate 261 abuts against the mounting cylinder 183, which will drive the U-shaped plate 261 to move towards the support column (taking the enlargement of the drilling diameter of the drilling plate 11 as an example; the operation is reversed when shrinking). Thus, the U-shaped plate 261 is pushed, the sliding plate 233 moves, driving the rigid rope to move, causing the outer toothed plate 212 to move upward, thereby rotating the gear 211, driving the inner toothed plate 212 to move downward, causing the replacement plate 2... 14 moves downwards to fill the gap at the bottom of the two drilling plates 11 after sorting. It is worth noting that although the replacement plate 214 fills the gap at the bottom of the drilling plate 11, there will still be some gaps on the side wall. At this time, the cylinder 10 can be rotated to open the entire hole. In addition, it should be noted that the replacement plate 214 moves in the arc groove 213, which makes the top of the arc groove 213 and the upper surface of the replacement plate have a gap. To prevent soil from entering the gap, a folded baffle or similar can be placed in this gap for blocking, or it can be manually cleaned after use.

[0046] In summary, by setting up a replacement mechanism, during the separation of the two drilling plates 11, the replacement plate 214 can be moved downwards through transmission to fill the gap formed between the two drilling plates 11 due to separation, ensuring that the seedling can be cut off from the root and ensuring the removal of the seedling.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
