Description

Technical Field

[0001] The utility model relates to the technical field of tobacco transplanters, in particular to a well-cellar type automatic tobacco transplanter. Background Art

[0002] Guizhou, my country has a distinct three-dimensional climate. Most tobacco-growing areas have low temperatures and little sunlight during the seedling raising period from January to March. When the best transplanting period for flue-cured tobacco arrives, it is difficult to cultivate "tall stem strong seedlings". The transplanting period is often postponed or weak seedlings are transplanted, and it is not possible to ensure that the tobacco plants grow and develop under suitable temperature, light and water conditions. In the later period, it is easily affected by summer drought, resulting in low tobacco yield and quality, and the characteristics of tobacco leaves cannot be fully demonstrated. Guizhou tobacco work must be started early to ensure that transplanting is completed by the end of April, and the best growing season for tobacco plants is arranged in the most suitable May to June to avoid the influence of summer drought weather in the later period. Therefore, the "well-cellar transplanting technology" was invented in this context and has been well promoted. The "well-cellar transplanting technology" is a transplanting method that transplants seedlings into a well-cellar of a certain size under the ridge body, realizing the cultivation of strong seedlings, timely early planting, and high ridge deep planting in the well-cellar at the same time, ensuring that the tobacco plants are in the best temperature, light and water in May and June.

[0003] The well cellar in the traditional "well cellar transplanting technology" requires a single person to walk and make holes with a hand-held well cellar maker, and other personnel follow to perform operations such as planting seedlings and adding water. This is time-consuming and labor-intensive, increases the workload of workers, and has low work efficiency. Therefore, it is necessary to develop an automated well cellar tobacco transplanter to replace manual labor with an automated machine. Only one transplanter can realize the integrated work of well cellar digging, transplanting and watering, thereby improving work efficiency.

[0004] There is a well-cellar type tobacco transplanter with a publication number of CN112753331A in the technology, which includes a vehicle body, a seedling throwing device is arranged on the vehicle body, a hole-forming and transplanting device is arranged below the seedling throwing device, a seedling placement rack is arranged above the seedling throwing device, and a linkage mechanism is installed on the vehicle body to drive the hole-forming and transplanting device to move synchronously with the seedling throwing device. By arranging a linkage mechanism on the vehicle body, the vehicle's movement, hole-forming, and seedling throwing are synchronously driven. A water pump is also fixed on the mounting seat, and the water outlet of the water pump extends into the transplanting tube through a conduit, realizing automatic water replenishment operation in the well-cellar hole, overcoming the manual watering operation of holding a water pipe in the traditional technology, reducing the labor of tobacco farmers, and improving work efficiency. The technical solution provided by this patent has the following two main shortcomings:

[0005] First, the hole-forming and transplanting device for digging wells in the patent adopts a crank transmission to drive the drill bit to work. Specifically, the mounting plate is fixed to the vehicle body, and the power of the vehicle body is transmitted to one of the cranks to drive the crank to rotate. The two cranks are connected with a connecting frame, which moves up and down with the connecting frame to simulate a parallelogram mechanism, so that the drill rod moves up and down under the driving action of the connecting frame, inserts into the soil to drill a hole, and uses a linkage to achieve that the drill rod rotates while moving vertically, so that not only drilling is achieved by downward pressure, but also rapid drilling is achieved by its own rotation; the main disadvantage of this method of digging wells is that in the transmission process of the crank driving the connecting frame, the force will be affected by friction loss, and there will be a part of energy loss, which leads to the situation that the well cannot be drilled when encountering a relatively hard soil layer, or the depth of the well is uneven. In addition, the mechanical transmission structure of this crank transmission is easily damaged during rapid work, with a high failure rate, and there is only one drill bit, and only one well can be drilled each time it is pressed down, and the work efficiency is also low.

[0006] Second, the linkage mechanism used in the seedling throwing device in the patent realizes that each time the crank rotates one circle, several seedling cups in the shape of a runway move one grid, and a seedling falls. When the transplanting tube moves to the bottom of the empty section, the seedling falls into the transplanting tube and is guided by the transplanting tube to the well cellar hole below. The movement of several seedling cups in this seedling throwing method depends on the linkage effect brought by the above-mentioned crank transmission method. The disadvantage is that the overall mechanical transmission structure is easy to damage, the failure rate is high, and it is easy to have a certain error after the transmission force is lost, resulting in inaccurate seedling throwing. The tobacco seedlings will easily be thrown outside the well cellar mouth, resulting in low work efficiency.

[0007] In addition to the above, there is a well-cellar type transplanting hole-forming mechanism with a publication number of CN112753331A in the technology, including a hole-forming frame, on which are mounted two non-circular gear mechanisms of the same structure, the two non-circular gear mechanisms being arranged front and back in parallel along the movement direction of the hole-forming frame, a power transmission mechanism being transmitted between the two non-circular gear mechanisms; the output ends of the two non-circular gear mechanisms are respectively fixedly connected with hole-forming cranks, the two hole-forming cranks are arranged in parallel and the top ends of the two hole-forming cranks are respectively fixedly mounted with crank connecting shafts, a horizontally arranged hole-forming connecting rod is hinged between the two crank connecting shafts, two bevel gear commutators corresponding to the two crank connecting shafts are fixedly mounted at the bottom end of the hole-forming connecting rod, a spur gear mechanism is transmitted between the input shaft of each bevel gear commutator and the corresponding crank connecting shaft, the output shaft of each bevel gear commutator is arranged vertically downward and a hole-forming device arranged vertically downward is fixed at the bottom end; the utility model can form a well-cellar with a regular shape and an approximately cylindrical well-cellar, which is used to meet the requirements of well-cellar insulation and moisture retention. The technical solution provided by this patent is similar to the above one. Although it is possible to drill two wells at the same time, the method adopted is still the crank-driven well-drilling method, so the same technical problems as above exist. Utility Model Content

[0045] In the above implementation column, please refer to Figure 4 The power unit 6 includes a left electric box 601 and a right electric box 602 installed on the rear end of the chassis frame 101 and located at both ends of the support frame 103, and a generator 603 installed on the right side of the fuselage frame 102.

[0046] In the above implementation column, please refer to Fig.10 The watering device 7 includes a fixing plate 701 installed on the inner side of the left side of the supporting frame 103, a third vertical slide module 702 is installed on the fixing plate 701, a third vertical servo motor 703 is installed on the top of the third vertical slide module 702, a vertically movable connecting plate 704 is slidably installed on the third vertical slide module 702, a horizontally placed first square tube 705 is installed on the vertically movable connecting plate 704, two ends of the first square tube 705 are respectively vertically connected to the second square tube 706 downward, the bottom ends of the two second square tubes 706 are respectively connected to the third party tubes 707 which are perpendicular to the first square tube 705, and the other ends of the two third party tubes 707 are vertically connected to the watering sprinkler 708 downward. The watering device 7 also includes a water tank 709 installed on the left side of the fuselage frame 102.

[0047] The working principle of the above embodiment is:

[0048] First, operators A and B sit on the first seat 105 and the second seat 107 respectively. Operator B operates various control levers and buttons on the control console 506 to make the driving walking device 5 work and control the transplanter to start, stop, turn right or turn left. Operator B operates the first gear lever 507 and the second gear lever 508 to control the transplanter to shift gears as needed. The generator 603 in the power device 6 can supply power to the left electric box 601 and the right electric box 602. The left electric box 601 and the right electric box 602 are used to supply power to the horizontal punching device 2, the seedling dropping device 4, the driving walking device 5, and the watering device 7.

[0049] Second, before starting to dig the well cellar, operator A puts the tobacco seedlings into the upper seedling guide tube 303 from the first funnel 304 of the upper seedling throwing device 3. The first movable door assembly 305 is initially in a closed state, and the tobacco seedlings thrown in will not fall. The horizontal servo motor 202 starts to work, driving the horizontal slide module 201 and the horizontal movable plate 203 installed on the horizontal slide module 201 to move horizontally toward the rear of the transplanter and adjust the position. At this time, the entrances of the second funnel 405 at the upper ends of the two lower seedling guide tubes 404 are respectively aligned with the outlets of the first movable door assembly 305 at the lower ends of the two upper seedling guide tubes 303 of the upper seedling throwing device 3.

[0050] Third, when digging a well, the first movable door assembly 305 is opened, and two groups of tobacco seedlings enter the lower seedling guide tube 404 from the upper seedling guide tube 303 along the entrance of the second funnel 405. The second movable door assembly 406 is initially closed, and the tobacco seedlings will not continue to fall, but stay in the lower seedling guide tube 404. The first vertical slide module 205 installed on the movable plate 203 is driven by the first vertical servo motor 206 to move downward, thereby driving the punching upper and lower movable plates 207 and the punching modules installed on the movable plate 207 to move downward. At the same time, the DC brushless motors 210 in the two punching modules drive the two punching drills 211 to punch the first group of two well holes at the current original position, and then the horizontal slide module 201 drives the punching module and the lower seedling device 4 to move forward by a fixed distance, and the tobacco seedlings already in the two lower seedling guide tubes 404 are simultaneously put into the two wells of the first group.

[0051] Fourth, after the first two tobacco seedlings in the above steps are planted, during the movement of the transplanter, the horizontal slide module 201 drives the punching module and the lower seedling device 4 to move backward a fixed distance. At this time, the two drilling drills 211 drill the second group of two well holes in the current original position, and then the horizontal slide module 201 drives the punching module and the lower seedling device 4 to move forward a fixed distance, and the tobacco seedlings that are subsequently put into the lower seedling guide tube 404 are simultaneously put into the two wells of the second group.

[0052] Fifth, in the process of drilling the second set of two wells in the above steps, two watering sprinklers 708 are respectively aimed at the two wells of the first set to pour a certain amount of water, and watering is stopped before the second seedling is put into the lower seedling guide tube 404.

[0053] Sixth, repeat the second step to the fifth step in sequence to complete the subsequent integrated actions of digging well holes, planting seedlings and watering.

[0054] Embodiment 2:

[0055] The difference from Example 1 is that the well-cellar type automatic tobacco transplanter, which is operated by two operators A and B, can be changed to be operated by only operator A. Operator A first sits on the second seat 107, sets the automatic forward instruction and the corresponding gear on the console 506, and then changes to the first seat 105. At this time, the transplanting machine automatically controls the movement, drilling well-cellar holes, transplanting seedlings and watering according to the set software program instructions. Operator A only needs to perform the seedling transplanting work alone.

[0056] In summary, the well-cellar type automatic tobacco transplanter is automatically controlled according to the set software program instructions, and moves forward in a repeated stepping manner by driving the walking device 5, and two well-cellar holes are punched at the same time by the horizontal punching device 2. After the upper seedling device 3 and the lower seedling device 4 cooperate with each other to complete the seedling transplanting of the tobacco seedlings, the transplanter moves forward and repeats the previous transplanting action, and the previously transplanted tobacco seedlings are watered by the watering device 7, so as to work in a cycle. The well-cellar type automatic tobacco transplanter integrates the well-cellar hole drilling, seedling throwing and watering, realizing integrated continuous operation. The special punching drill 211 has a fast drilling speed, and the well-cellar holes are formed in one time. The overall transplanter has high working efficiency, comprehensive performance and a wide range of practical applications.
