Description

Technical Field

[0001] The invention relates to the technical field of agricultural transplanting machinery, and in particular to a paper pot seedling transplanting machine and a transplanting method. Background Art

[0002] In agricultural production, many plants need to be transplanted to optimize their growth environment. Transplanting can ensure that plants get more suitable soil conditions, light and water, thereby improving yield and quality. In recent years, the use of degradable paper pots for seedling cultivation has gradually become popular. This method is not only environmentally friendly, but also can significantly improve seedling efficiency and transplant survival rate.

[0003] The advantage of paper pot seedling cultivation is that it has good air permeability, can promote root development, reduce root damage when lifting seedlings, and basically has no seedling slowing period after transplanting. In addition, paper pots are degradable, which reduces the environmental pollution caused by traditional seedling containers. When transplanting paper pot seedlings, there is no need to remove the outer layer of paper, which is easy to operate, and can effectively protect the root system and reduce losses during transportation. Therefore, using degradable paper pots to grow seedlings and then transplanting them can not only increase the growth rate and yield of plants, but also promote the sustainable development of agricultural production.

[0004] The applicant's prior application CN117441459A discloses a vegetable transplanter suitable for paper pot seedlings, which has a seedling rack, a seedling separation mechanism, a buffer device and a transplanting mechanism. In actual use, the above-mentioned transplanter has the following disadvantages:

[0005] (1) It is labor-intensive to take the paper pot seedlings from the seedling rack to the conveyor belt of the seedling separation mechanism, and it is difficult to ensure the arrangement effect of the paper pot seedlings on the conveyor belt. It is easy to place them crookedly, which affects the subsequent seedling separation operation;

[0006] (2) During the operation of the seedling separation mechanism, the interval between adjacent paper pot seedlings is short, which makes them easily blocked in the guide bucket. Unless the motor is frequently started and stopped, the interval between seedlings cannot be adjusted. Therefore, a more reasonable seedling separation mechanism needs to be designed. Summary of the invention

[0007] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides an efficient paper pot seedling transplanter and a transplanting method that can achieve efficient feeding of paper pot seedlings and reduce the failure rate of paper pot seedling separation.

[0008] Technical solution: To achieve the above-mentioned purpose, the paper pot seedling transplanter of the present invention comprises a walking machine base, the walking machine base comprises a frame, the frame is equipped with front wheels, rear wheels and a traction mechanism; the walking machine base is equipped with a paper pot seedling rack, a seedling separation device, a circulating seedling cup mechanism and a transplanting actuator; a seedling basket is placed on the paper pot seedling rack, and the seedling basket is equipped with paper pot seedlings;

[0009] The seedling separation device comprises a first conveyor belt and a first seedling separation mechanism installed at one end of the first conveyor belt, and also comprises a guide bucket for guiding the paper pot seedlings to the seedling cups in the circulating seedling cup mechanism; the first seedling separation mechanism comprises a first roller body and a second roller body;

[0010] It also includes a whole-row seedling taking device capable of transferring the paper pot seedlings in the seedling basket to the seedling separation device;

[0011] The whole-row seedling retrieval device includes a backing plate and a rotating frame that can rotate relative to the backing plate, and a plurality of seedling retrieval needles arranged in an equidistant array are fixed on the rotating frame; when taking seedlings, the seedling retrieval needles can keep the paper pot seedlings on the outside of the backing plate; when unloading the seedlings, the seedling retrieval needles leave the back side of the backing plate, and the seedling retrieval needles are located at the top position of the backing plate as a whole.

[0012] The side of the seedling basket facing the seedling separation device is an open side without a side plate; the abutment plate can enter the seedling basket from the open side;

[0013] The abutment plate can reciprocate between the seedling basket and the first conveyor belt; when the whole row of seedling taking devices takes seedlings from the seedling basket, the abutment plate is in a vertical state; when the whole row of seedling taking devices unloads seedlings from the first conveyor belt, the abutment plate is in a horizontal state.

[0014] Furthermore, the seedling separation device further comprises a second conveyor belt connected to the tail of the first conveyor belt, and the first seedling separation mechanism is arranged at the connection position between the first conveyor belt and the second conveyor belt; a second seedling separation mechanism is installed at the tail of the second conveyor belt, and the second seedling separation mechanism comprises a third roller body and a fourth roller body, and the third roller body is closer to the tail of the second conveyor belt than the fourth roller body;

[0015] The first roller and the third roller are active rollers, the center axis of the first roller is placed above the second conveyor belt, the surface linear velocities V1, V2, and V3 of the first roller, the second conveyor belt, and the third roller are equal, and the surface linear velocities of the three are all greater than the surface linear velocity V4 of the first conveyor belt; the second roller and the fourth roller are driven rollers, and the center axis of the second roller is located above the first conveyor belt.

[0016] During the seedling separation operation, since the first conveyor belt and the second conveyor belt have a speed difference, and the first roller body and the second roller body are respectively the active roller and the driven roller, the second roller body can have a blocking effect on the paper pot seedlings. Combined with the speed difference between the two conveyor belts, the adjacent paper pot seedlings can be effectively separated so that there is a gap between the adjacent paper pot seedlings after they reach the second conveyor belt. The larger the speed difference, the larger the gap. In the second seedling separation mechanism, the posture of the paper pot seedlings can be regularized by the action of the fourth roller body and the second conveyor belt, and then combined with the clamping and conveying action of the third roller body and the second conveyor belt, the consistency of the posture of the fallen seedlings can be maintained, ensuring that after the paper pot seedlings fall, they can smoothly enter the seedling cup of the circulating seedling cup mechanism after being guided by the guide bucket.

[0017] Furthermore, the seedling separation device also includes a third conveyor belt connected to the first conveyor belt; the second conveyor belt and the third conveyor belt are narrower than the first conveyor belt, and the third conveyor belt is shorter than the second conveyor belt. In addition, the position of the third conveyor belt is higher than that of the second conveyor belt; the conveying line speed of the third conveyor belt is the same as that of the second conveyor belt. The second conveyor belt is used to support the paper pot part of the paper pot seedlings, and the third conveyor belt is used to press the head of the seedlings of the paper pot seedlings. Since the conveying line speeds of the second conveyor belt and the third conveyor belt are the same, after the paper pot seedlings leave the first conveyor belt, their paper pot part and seedling part are respectively acted upon by the second conveyor belt and the third conveyor belt to move forward at the same speed. The third conveyor belt can cause the seedling part to detach from the first conveyor belt, and the paper pot seedlings will not be pulled crooked as a whole due to the relatively scattered seedling parts and some of them not detaching from the first conveyor belt. Since the third conveyor belt is shorter than the second conveyor belt, the seedling part of the paper pot seedlings will detach from the tail of the third conveyor belt in advance before the paper pot part of the paper pot seedlings reaches the second seedling separation mechanism. In this way, after the paper pot part of the paper pot seedlings detaches from the second conveyor belt, the falling paper pot seedlings will not be skewed due to the fact that part of the seedling part is still overlapped on the third conveyor belt.

[0018] Furthermore, the first conveyor belt is driven by the first motor; the second conveyor belt, the third conveyor belt, the first roller body and the third roller body are all driven by the second motor, so that the surface linear speed of the four can be synchronized, reducing the control difficulty. During control, the seedling dropping interval can be changed by controlling the speed difference between the first motor and the second motor.

[0019] Furthermore, in the first solution, a first handle is fixed on the abutment plate, and the gripping portion of the first handle is arranged vertically to facilitate switching the abutment plate between the horizontal state and the vertical state; a second handle is fixed on the rotating frame, and the gripping portion of the second handle is arranged horizontally to facilitate pulling the rotating frame to rotate relative to the abutment plate. In this solution, there is no connection between the whole row of seedling retrieval devices and the walking machine seat. The user holds the first handle and the second handle with both hands at the same time, so that the two can work together to realize the operation of taking seedlings from the seedling basket and unloading seedlings at the first conveyor belt.

[0020] Furthermore, in the second scheme, in order to facilitate user operation, the walking machine seat is provided with an auxiliary mechanism, and the auxiliary mechanism includes a telescopic device composed of a rotating seat and a connecting rod that can slide relative to each other, and also includes an elastic pulling mechanism connecting the walking machine seat and the rotating seat; the rotating seat is rotatably installed on the frame of the walking machine seat, and the rotating seat is installed at the end of the connecting rod, and a spring is installed in the rotating seat to apply a pull-back force to the connecting rod; an operating handle is installed on the abutment plate, and an electric cylinder is connected between the abutment plate and the rotating frame, and a button that can control the extension or shortening of the electric cylinder is connected to the operating handle.

[0021] The above structure can provide assistance and support for seedling removal and reduce labor intensity.

[0022] Furthermore, a seat is installed on the walking machine seat.

[0023] Furthermore, the circulating seedling cup mechanism includes a plurality of cache seedling cups, all of which constitute a seedling cup chain, and also includes a driving mechanism capable of driving the seedling cup chain to circulate; each of the cache seedling cups reaches a release position above the transplanting actuator and can be opened to allow the paper pot seedlings therein to fall out.

[0024] Furthermore, the transplanting actuator is a duckbill type transplanting mechanism.

[0025] A paper pot seedling transplanting method, which is applied to the above-mentioned paper pot seedling transplanting machine, the method comprises steps S1-S4:

[0026] Step S1: taking a whole row of seedlings in paper pots from the seedling basket on the paper pot seedling rack by the whole row seedling taking device, and unloading the whole row of seedlings in paper pots onto the first conveyor belt;

[0027] Step S2: the seedling separation device arranges the paper pot seedlings that are closely arranged on the first conveyor belt separately, and then separates the paper pot seedlings in sequence, and the fallen paper pot seedlings enter the buffer seedling cup of the circulating seedling cup mechanism;

[0028] Step S3: each buffer seedling cup in the circulating seedling cup mechanism passes through the release position in turn and releases the paper pot seedlings therein;

[0029] Step S4: the transplanting execution mechanism receives the paper pot seedlings released by the buffer seedling cup and transplants the paper pot seedlings into the soil.

[0030] Beneficial effects: The paper pot seedling transplanter and transplanting method of the present invention have the following beneficial effects:

[0031] (1) By setting up a whole-row seedling retrieval device, the paper pot seedlings in the seedling basket can be transferred to the first conveyor belt row by row, and the seedling separation device then separates the rows of paper pot seedlings. Combined with the circulating seedling cup mechanism, the seedlings are supplied to the transplanting actuator. The whole-row seedling retrieval device can greatly improve the seedling retrieval efficiency and ensure the regularity of the paper pot seedlings on the first conveyor belt, thereby ensuring the separation and subsequent transplanting effects.

[0032] (2) On the basis of the prior application, a second conveyor belt and a second seedling separation mechanism are added, and the relationship between the surface linear speed of each conveyor belt and the active roller is reset, so that the paper pot seedlings closely arranged on the first conveyor belt can first pass through the first seedling separation mechanism and then reach the second conveyor belt and be dispersed and arranged, and then pass through the second seedling separation mechanism and drop the seedlings to the circulating seedling cup mechanism. Through the above process, it is possible to avoid the seedling drop failure caused by the blockage in the guide bucket due to the short drop interval, and the seedling drop interval can also be adjusted by adjusting the speed difference between the first conveyor belt and the second conveyor belt. The adjustment range of the seedling drop interval is very large and can fully meet different transplanting needs. In addition, the second seedling drop mechanism can ensure the drop posture of the paper pot seedlings and ensure the stable operation of the subsequent process.

[0033] (3) By providing a third conveyor belt and specifically setting the width relationship, length relationship and speed relationship among the first conveyor belt, the second conveyor belt and the third conveyor belt, the seedling falling posture of the paper pot seedlings can be ensured.

DETAILED DESCRIPTION

[0045] The present invention will be further described below in conjunction with the accompanying drawings.

[0046] like Figures 1 to 3 The paper pot seedling transplanter shown includes a walking machine base 1, which includes a frame 11, on which a front wheel 12, a rear wheel 13 and a traction mechanism 14 are installed; a paper pot seedling rack 2, a seedling separation device 3, a circulating seedling cup mechanism 4 and a transplanting actuator 5 are installed on the walking machine base 1; a seedling basket 6 is placed on the paper pot seedling rack 2, and the seedling basket 6 contains paper pot seedlings a.

[0047] The seedling separation device 3 includes a first conveyor belt 31 and a first seedling separation mechanism installed at one end of the first conveyor belt 31, and also includes a guide bucket 37 that guides the paper pot seedlings a to the seedling cup in the circulating seedling cup mechanism 4; the first seedling separation mechanism includes a first roller body 32 and a second roller body 33.

[0048] The transplanter also includes a row of seedlings 7 capable of transferring the paper pot seedlings a in the seedling basket 6 to the seedling separation device 3; Figure 4 As shown, the whole row seedling removal device 7 includes a support plate 71 and a rotating frame 72 that can rotate relative to the support plate 71, and a plurality of seedling removal needles 73 arranged in an equidistant array are fixed on the rotating frame 72; when removing seedlings, the seedling removal needles 73 can keep the paper pot seedlings a on the outside of the support plate 71, as shown in FIG. Figure 5 When unloading the seedlings, the seedling needle 73 leaves the back side of the abutment plate 71, and the seedling needle 73 is located at the top position of the abutment plate 71 as a whole.

[0049] The side of the seedling basket 6 facing the seedling separating device 3 is an open side without a side plate; the abutment plate 71 can enter the seedling basket 6 from the open side.

[0050] The abutment plate 71 can reciprocate between the seedling basket 6 and the first conveyor belt 31; when the whole-row seedling taking device 7 takes seedlings from the seedling basket 6, the abutment plate 71 is in a vertical state; when the whole-row seedling taking device 7 unloads seedlings from the first conveyor belt 31, the abutment plate 71 is in a horizontal state. Figure 6 and Figure 7 shown.

[0051] By setting up a whole-row seedling retrieval device 7, the paper pot seedlings a in the seedling basket 6 can be transferred row by row to the first conveyor belt 31, and the seedling separation device 3 then separates the rows of paper pot seedlings a. Combined with the circulating seedling cup mechanism 4, the seedlings are supplied to the transplanting actuator 5. The whole-row seedling retrieval device 7 can greatly improve the seedling retrieval efficiency, and ensure the regularity of the arrangement of the paper pot seedlings a on the first conveyor belt 31, thereby ensuring the seedling separation and subsequent transplanting effects.

[0052] Preferably, if Figure 8 and Fig. 9 As shown, the seedling separation device 3 also includes a second conveyor belt 34 connected to the tail of the first conveyor belt 31, and the first seedling separation mechanism is arranged at the connection position between the first conveyor belt 31 and the second conveyor belt 34; the tail of the second conveyor belt 34 is installed with a second seedling separation mechanism, and the second seedling separation mechanism includes a third roller body 35 and a fourth roller body 36, and the third roller body 35 is closer to the tail of the second conveyor belt 34 than the fourth roller body 36; the first roller body 32 and the third roller body 35 are active rollers, and the central axis of the first roller body 32 is placed above the second conveyor belt 34, and the surface linear velocities V1, V2, and V3 of the first roller body 32, the second conveyor belt 34, and the third roller body 35 are equal, and the surface linear velocities of the three are all greater than the surface linear velocity V4 of the first conveyor belt 31; the second roller body 33 and the fourth roller body 36 are driven rollers, and the central axis of the second roller body 33 is located above the first conveyor belt 31.

[0053] During the seedling separation operation, since the first conveyor belt 31 and the second conveyor belt 34 have a speed difference, and the first roller body 32 and the second roller body 33 are respectively the active roller and the driven roller, the second roller body 33 can have a blocking effect on the paper pot seedling a. Combined with the speed difference between the two conveyor belts, the adjacent paper pot seedlings a can be effectively separated so that a gap is generated after the adjacent paper pot seedlings a reach the second conveyor belt 34. The larger the speed difference, the larger the generated gap. In the second seedling separation mechanism, the posture of the paper pot seedling a can be regularized by the action of the fourth roller body 36 and the second conveyor belt 34, and then combined with the clamping and conveying action of the third roller body 35 and the second conveyor belt 34, the consistency of the seedling posture can be maintained, ensuring that after the paper pot seedling a falls, it can smoothly enter the seedling cup of the circulating seedling cup mechanism 4 after being guided by the guide bucket 37.

[0054] It can be seen that in the above structure, the second conveyor belt 34 and the second seedling separation mechanism are added on the basis of the prior application, and the relationship between the surface linear speed of each conveyor belt and the active roller is reset, so that the paper pot seedlings a arranged closely on the first conveyor belt 31 can be dispersed after passing through the first seedling separation mechanism and then arriving on the second conveyor belt 34, and then falling to the circulating seedling cup mechanism 4 after passing through the second seedling separation mechanism. Through the above process, it can be avoided that the seedling falling interval is too short and blocked in the guide bucket 37, resulting in seedling falling failure, and the seedling falling interval can be adjusted by adjusting the speed difference between the first conveyor belt 31 and the second conveyor belt 34. The adjustment range of the seedling falling interval is very large, which can fully meet different transplanting needs. In addition, the second seedling falling mechanism can ensure the seedling falling posture of the paper pot seedlings a and ensure the stable operation of the subsequent process.

[0055] Preferably, the seedling separation device 3 further includes a third conveyor belt 38 connected to the first conveyor belt 31; the second conveyor belt 34 and the third conveyor belt 38 are narrower than the first conveyor belt 31, and the third conveyor belt 38 is shorter than the second conveyor belt 34. In addition, the position of the third conveyor belt 38 is higher than that of the second conveyor belt 34; the conveying line speed of the third conveyor belt 38 is the same as that of the second conveyor belt 34. The second conveyor belt 34 is used to hold the paper pot part of the paper pot seedling a, and the third conveyor belt 38 is used to press the head of the seedling of the paper pot seedling a, that is, the head of the seedling affected by the third conveyor belt 38 is located below the third conveyor belt 38. Since the conveying line speeds of the second conveyor belt 34 and the third conveyor belt 38 are the same, after the paper pot seedling a leaves the first conveyor belt 31, its paper pot part and the rice seedling part are respectively acted upon by the second conveyor belt 34 and the third conveyor belt 38 to advance at the same speed, and the third conveyor belt 38 can cause the rice seedling head to separate from the first conveyor belt 31, and the paper pot seedling a will not be pulled crooked as a whole due to the relatively scattered rice seedling part and part of it not being separated from the first conveyor belt 31. Since the third conveyor belt 38 is shorter than the second conveyor belt 34, before the paper pot part of the paper pot seedling a reaches the second seedling separation mechanism, the rice seedling part is separated from the tail of the third conveyor belt 38 in advance, so that after the paper pot part of the paper pot seedling a separates from the second conveyor belt 34, the falling paper pot seedling a will not be crooked due to the rice seedling part still being partially overlapped on the third conveyor belt 38.

[0056] It can be seen that by providing the third conveyor belt 38 and specifically setting the width relationship, length relationship and speed relationship among the first conveyor belt 31, the second conveyor belt 34 and the third conveyor belt 38, the seedling falling posture of the paper pot seedling a can be ensured.

[0057] Preferably, the first conveyor belt 31 is driven by the first motor 39; the second conveyor belt 34, the third conveyor belt 38, the first roller 32 and the third roller 35 are all driven by the second motor 310, so that the surface linear speed of the four can be synchronized and the control difficulty can be reduced. During control, the seedling drop interval can be changed by controlling the speed difference between the first motor 39 and the second motor 310.

[0058] Specifically, the second motor 310 directly drives the second conveyor belt 34 to operate, and the second motor 310 drives the third conveyor belt 38 to operate through a set of chain mechanisms b and a pair of mutually meshing gears c, so that the conveying speed of the lower belt segment of the third conveyor belt 38 can be equal to the speed of the upper belt segment of the second conveyor belt 34.

[0059] In the first embodiment, if Figure 4As shown, a first handle 74 is fixed on the abutment plate 71, and the gripping portion of the first handle 74 is arranged vertically to facilitate switching the abutment plate 71 between the horizontal state and the vertical state; a second handle 75 is fixed on the rotating frame 72, and the gripping portion of the second handle 75 is arranged horizontally to facilitate pulling the rotating frame 72 to rotate relative to the abutment plate 71. In this embodiment, there is no connection between the whole row of seedling taking devices 7 and the walking machine base 1. The user holds the first handle 74 and the second handle 75 with both hands at the same time, so that the two can work together to achieve the operation of taking seedlings from the seedling basket 6 and unloading seedlings at the first conveyor belt 31.

[0060] In the second embodiment, in order to facilitate the user to operate, Fig.10 As shown, the walking machine seat 1 is provided with an auxiliary mechanism 8, and the auxiliary mechanism 8 includes a telescopic device composed of a rotating seat 81 and a connecting rod 82 that can slide relative to each other, and also includes an elastic pulling mechanism 83 connecting the walking machine seat 1 and the rotating seat 81; the rotating seat 81 is rotatably installed on the frame 11 of the walking machine seat 1, and the rotating seat 81 is installed at the end of the connecting rod 82, and a spring is installed in the rotating seat 81 to apply a pulling force to the connecting rod 82; an operating handle 84 is installed on the abutment plate 71, and an electric cylinder 85 is connected between the abutment plate 71 and the rotating frame 72, and a button that can control the extension or shortening of the electric cylinder 85 is connected to the operating handle 84.

[0061] With the above structure, when taking out seedlings, the abutment plate 71 can be pushed by the operating handle 84 to make the abutment plate 71 enter the seedling basket 6 from the open side and abut against the outermost row of paper pot seedlings a. Then, the electric cylinder 85 is extended by the button control so that the needle tip of the seedling taking needle 73 is inserted into the paper pot of each paper pot seedling a, and a row of paper pot seedlings a is kept fixed on the outer side of the abutment plate 71. Then, the abutment plate 71 is pulled back (the pulling back effect of the spring can assist the connecting rod 82 to slide relative to the rotating seat 81 to assist the pulling back of the abutment plate 71), and then the abutment plate 71 is turned downward so that the abutment plate 71 becomes a horizontal state. Since the abutment plate 71 with a whole row of paper pot seedlings a is heavier, it overcomes the effect of the elastic pull-up mechanism 83 and descends until the paper pot seedlings a arrive on the first conveyor belt 31. During this process, the elastic pull-up mechanism 83 plays a slow-down effect. At this time, the abutment plate 71 and the first conveyor belt 31 sandwich the paper pot seedlings a in the middle. The seedling needle 73 can be separated from the paper pot seedlings a by pressing a button. Finally, the abutment plate 71 with the paper pot seedlings a removed is lighter, and the elastic pull-up mechanism 83 pulls the abutment plate 71 upward, so that the abutment plate 71 is separated from the paper pot seedlings a, completing a seedling removal operation. Repeating the operation in sequence can achieve continuous seedling removal.

[0062] The above structure can provide assistance and support for seedling removal and reduce labor intensity.

[0063] A seat 9 is installed on the walking machine base 1 .

[0064] The circulating seedling cup mechanism 4 includes a plurality of buffer seedling cups 41, all of which constitute a seedling cup chain, and also includes a driving mechanism capable of driving the seedling cup chain to circulate; each buffer seedling cup 41 reaches a release position above the transplanting actuator 5 and can be opened to allow the paper pot seedlings a therein to fall out.

[0065] The transplanting actuator 5 is a duckbill type transplanting mechanism.

[0066] The present invention also provides a paper pot seedling transplanting method, which is applied to the above-mentioned paper pot seedling transplanting machine, and the method comprises steps S1-S4:

[0067] Step S1: taking a whole row of paper pot seedlings a from the seedling basket 6 on the paper pot seedling rack 2 by the whole row seedling taking device 7, and unloading the whole row of paper pot seedlings a taken onto the first conveyor belt 31;

[0068] Step S2: the seedling separation device 3 first arranges the paper pot seedlings a arranged closely on the first conveyor belt 31 separately, and then separates the paper pot seedlings a in sequence, and the fallen paper pot seedlings a enter the buffer seedling cup 41 of the circulating seedling cup mechanism 4;

[0069] Step S3: each buffer seedling cup 41 in the circulating seedling cup mechanism 4 passes through the release position in turn and releases the paper pot seedlings a therein;

[0070] Step S4: the transplanting execution mechanism 5 receives the paper pot seedlings a released by the buffer seedling cup 41 and transplants the paper pot seedlings a into the soil.

[0071] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
