Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and in particular to a transplanting device, method and transplanting machine capable of cleaning duck bills in real time. Background Art

[0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] At present, transplanting work has gradually been replaced by automatic or semi-automatic machinery from traditional manual complex operations. This type of transplanting machinery is mainly duck-bill transplanters. For example, duck-bill tobacco transplanters for transplanting tobacco seedlings have appeared. Due to the particularity of the principle and structure of the duck-bill transplanting device carried on the tobacco transfer machine, during transplanting, the duckbill needs to continuously open and close in the soil, and the inner wall of the duckbill will often adhere to some soil and various impurities. This phenomenon is particularly obvious in clay soil. If the impurities adhered to the inner wall of the duckbill are not cleaned in time, these impurities will gradually become thicker as the number of transplants increases, and eventually the movement of the tobacco seedlings in the duckbill will be hindered, affecting the planting effect of the tobacco seedlings. At present, the cleaning of the duckbill is mainly done manually, which requires downtime, increasing the labor intensity of the staff, affecting the progress of the transplanting work, and reducing the efficiency of the transplanting work. Summary of the invention

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a transplanting mechanism capable of cleaning the duck's bill in real time, eliminating the need for manual cleaning of the duck's bill and improving the efficiency of transplanting.

[0005] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0007] Optionally, the lifting mechanism includes a rotating driving member fixed to the frame, the output shaft of the rotating driving member is fixedly connected to one end of the crank, the other end of the crank is hinged to one end of the connecting rod, and the other end of the connecting rod is hinged to the slip ring.

[0008] Optionally, a bearing is provided inside the slip ring, an inner ring of the bearing is fixed to the screw nut, and an outer ring of the bearing is fixed to the inner side surface of the slip ring.

[0010] Optionally, the detection element is a photoelectric proximity switch.

[0011] Optionally, a retaining ring is provided at the bottom end of the ball screw.

[0012] Optionally, the brush assembly includes a brush sleeve and a plurality of brushes fixed on the outer circumference of the brush sleeve, and the brush sleeve is fixedly connected to the screw nut of the ball screw assembly.

[0013] Optionally, the length of the brush is greater than the length of the brush cover, and the top of the brush is flush with the top of the brush cover;

[0014] Furthermore, the length of the brush cover is 1 / 4 of the length of the brush.

[0015] In the second aspect, an embodiment of the present invention provides a working method for a transplanting mechanism capable of real-time cleaning of duckbills as described in the first aspect: multiple transplanting duckbills of an eccentric disc duckbill transplanting mechanism rotate along a circle, and when the duckbills to be cleaned rotate to a cleaning station directly below the cleaning mechanism, the lifting mechanism works, driving the lead screw nut of the roller screw assembly to descend through a slip ring, and the lead screw nut descends while rotating around its own axis, driving the brush assembly to descend while rotating around its own axis, and the brush assembly extends into the duckbills of the cleaning station to clean the duckbills. After cleaning, the lifting mechanism drives the brush assembly to rise and leave the duckbills, and the cleaned duckbills continue to move to directly below the seedling releaser to receive the pot seedlings dropped from the seedling releaser.

[0016] In a third aspect, an embodiment of the present invention provides a transplanter provided with the transplanting mechanism capable of cleaning the duckbill in real time as described in the first aspect.

[0019] 2. In the transplanting mechanism of the present invention, the length of the brush cover is smaller than the length of the brush, and the top of the brush is flush with the top of the brush cover, so that the bottom of the brush is not supported by the brush cover. This helps the bottom of the brush to shrink along the shape of the inner wall of the duck's bill when the brush enters the duck's bill, better fit the inner wall of the duck's bill, and better clean the impurities.

[0020] 3. The transplanting mechanism and lifting mechanism of the present invention adopt a crank-connecting rod mechanism, which is combined with a ball screw assembly, with high space utilization.

[0034] Example 1

[0035] This embodiment provides a transplanting device capable of cleaning duckbill in real time, such as Figure 1 As shown, it includes a frame, on which are arranged a seedling throwing mechanism 7, a seedling placing device 8 and an eccentric disc duckbill transplanting mechanism 9; the front end of the frame is provided with a seedling throwing mechanism 7, the seedling throwing mechanism is provided with a plurality of seedling throwing tubes, a seedling placing device 8 is provided below the seedling emergence station of the seedling throwing mechanism, the seedling placing device 8 is used to guide the thrown pot seedlings into the duckbill 10, an eccentric disc duckbill transplanting mechanism 7 is provided at the rear and lower part of the seedling placing device 8, the eccentric disc duckbill transplanting mechanism 7 has a plurality of duckbill 10 distributed along the circumference, the plurality of duckbill 10 can move along the circumference, when moving to the bottom of the seedling placing device 8, can receive the pot seedlings dropped by the seedling placing device 8, when moving to the bottom, can be inserted into the soil and transplant the pot seedlings into the soil.

[0036] The structures, connection methods and working principles of the frame, seedling throwing mechanism 7, seedling placing device 8 and eccentric disc duckbill transplanting mechanism 9 can be made by using the existing technology, and no further detailed description is given here.

[0037] This embodiment improves upon the existing duckbill transplanting mechanism by adding a cleaning mechanism to clean the duckbill in real time.

[0038] like Figure 2 As shown, in this embodiment, along the forward direction of the transplanter, the cleaning mechanism is arranged behind the seedling releaser 8 and installed on the frame, including a fixed plate 1 and a ball screw assembly 3 installed on the fixed plate 1, a lifting mechanism, a brush assembly 4, an electronic control system 2, etc.

[0039] The fixing plate 1 is fixedly connected to the frame body by a plurality of bolts, and a ball screw assembly 3 and a lifting mechanism are installed on the fixing plate 1 .

[0040] The fixing plate 1 is formed by cutting and bending a steel plate, and has a plurality of through holes drilled therein, which are respectively used for installing the rotating drive member, the ball screw assembly and the electric control system of the lifting mechanism, and for installing the fixing plate itself on the frame of the transplanting mechanism.

[0041] like Figure 3 As shown, the ball screw assembly 3 can be an existing ball screw nut pair, which includes a screw fixing block 301, a screw 302, a ball screw plug 303, a screw nut 304 and a retaining ring 305. The screw fixing block 301 is fixedly connected to the flange provided at the end of the fixing plate 1 by a plurality of bolts, and its function is to install and fix the screw 302 to the mounting fixing plate 1 to prevent the screw 302 from rotating. The axis of the screw rod 302 is arranged vertically. After the screw rod 302 passes through the screw rod fixing block 301, the top end of the screw rod 302 is threadedly connected with a locking nut. The locking nut is pressed against the top surface of the screw rod fixing block 301 to fix the screw rod 302. The screw rod 302 and the screw rod nut 304 cooperate with each other. Specifically, the inner side of the screw rod nut 304 contains a spiral hemispherical thread that is consistent with the spiral hemispherical thread on the screw rod, and a spiral spring type ball channel is formed between the two. The screw rod nut 304 is an internal circulation ball screw nut. There are many balls (i.e., steel balls) between the screw rod nut 304 and the screw rod 302. When the screw rod nut 304 moves, the many balls inside it will also continuously circulate and roll, which makes the screw rod nut 304 inevitably rotate along the axial direction of the screw rod 302 when it moves linearly along the axial direction of the screw rod 302. This kind of motion can make the screw nut 304 produce any kind of motion and also inevitably produce another kind of motion, so that the brush assembly 4 connected thereto will produce rotational motion in the duckbill 10 whether entering or exiting (the rotation direction is different when entering and exiting), and this kind of rotational motion will not be interrupted in theory. The ball screw plug 303 is arranged on the screw nut 304, and its function is to block the ball inside the screw nut 304, and play a sealing role. It can be opened when necessary to replace the ball or add lubricant for lubrication. The ball screw assembly can adopt the existing technology, and its further technical details are not described in detail here.

[0042] Furthermore, the retaining ring 305 is disposed at the bottom end of the screw rod 302 to limit the downward movement of the screw rod nut 304 and prevent the screw rod nut 304 from falling off the screw rod 302 .

[0043] like Figure 4As shown, the lifting mechanism includes a rotating drive member, which adopts a servo motor 6. The servo motor 6 is arranged on one side of the screw fixing block. The servo motor 6 is fixed to the flange at the end of the fixing plate by multiple bolts. The output shaft of the servo motor is connected to the crank-connecting rod mechanism 5. Specifically, the output shaft of the servo motor is fixedly connected to one end of the crank by bolts or a pin shaft, and the other end of the crank 501 is hinged to one end of the connecting rod 502. The crank 501 and the connecting rod 502 together constitute the crank-connecting rod mechanism 5, and the other end of the connecting rod 502 is hinged to the slip ring 503.

[0044] The slip ring 503 is sleeved on the outer periphery of the screw nut 304, and a bearing 504 is provided on its inner side. The slip ring 503 is rotatably connected to the screw nut 304 through the bearing 504. Specifically, the outer ring of the bearing 504 is fixedly connected to the inner ring surface of the slip ring 503, and the inner ring of the bearing 504 is fixedly connected to the screw nut 304.

[0045] The crank-connecting rod mechanism 5 is combined with the ball screw assembly 3 in such a way that the crank-connecting rod mechanism 5 provides axial movement for the screw nut 304 without being reacted by the rotational movement of the screw nut 304 .

[0046] The screw nut 304 is connected to the brush assembly 4, and can drive the brush assembly 4 to move up and down, and drive the brush assembly 4 to rotate around its own axis.

[0047] In this embodiment, the axes of the screw rod 302, the screw rod nut 304, the multiple duck bills 10, the seedling releaser 9, and the brush assembly 4 are located in the same vertical plane, so that the duck bill 10 can move to the bottom of the brush assembly 4, making it convenient for the brush assembly 4 to extend into the duck bill 10 and leave the duck bill.

[0048] The position directly below the brush assembly 4 is a cleaning station. When the duckbill rotates 10 to the cleaning station, cleaning work can be carried out. A detection element is provided on one side of the cleaning station, and the detection element is used to detect whether the duckbill enters the cleaning station.

[0049] Preferably, the detection element adopts a photoelectric proximity switch 11, and the photoelectric proximity switch 11 is installed and fixed to the support beam next to the eccentric wheel of the eccentric disc duckbill transplanting mechanism. It can be understood that the photoelectric proximity switch 11 can also be installed at other frame positions, and technical personnel in this field can set it according to actual needs.

[0050] The photoelectric proximity switch 11 is connected to the electric control system and can transmit signals to the electric control system.

[0051] In this embodiment, Figure 5As shown, the electric control system 2 is installed on the fixed plate 1, located on one side of the screw fixing block 301, and the electric control system 1 includes a controller 201 and a driver 202. The controller 201 is connected to the driver 202 and can send control instructions to the driver 202. The driver 202 is connected to the servo motor 6 through a wiring harness. The controller 201 can control the servo motor 6 to work through the driver 202. The controller 201 is connected to the photoelectric proximity switch 11 through a sensor signal line, and the photoelectric proximity switch 11 can send a signal to the controller 201.

[0052] Furthermore, the servo motor 6 is also equipped with an encoder 12, which is connected to the controller 201 via a wiring harness. The controller 201 can collect the electrical signal (motor speed, position and other data) fed back by the encoder 12 to adjust and correct various working parameters of the servo motor in real time.

[0053] The encoder 12 and the connection method with the servo motor 6 can adopt the existing technology and will not be described in detail here.

[0054] The power required by the servo motor 6 is provided by the transplanter, the power supply 13 is connected to the driver through a power line, and the driver is connected to the servo motor through a power line.

[0055] The electric control system 2 plays a very important role in the working accuracy of the entire transplanting mechanism and whether it can achieve better coordination with the transplanter during operation. During operation, when the photoelectric proximity switch 11 generates an electrical signal, the controller 201 receives the signal and sends a control command to the driver 202. The driver 202 controls the servo motor 6 to start rotating and drive the lifting mechanism. The output shaft of the servo motor 6 is provided with an encoder 12 directly connected to the controller 201. The controller 201 can collect the electrical signal (motor speed, position and other data) fed back by the encoder 12 to adjust and correct the various working parameters of the servo motor 6 in real time.

[0056] like Figure 6 As shown, the brush assembly 4 includes a fixed sleeve 401, and a plurality of brushes 402 are circumferentially arranged on the outer periphery of the fixed sleeve 401. Preferably, the plurality of brushes 402 are circumferentially arranged at equal intervals along the circumference of the fixed sleeve 401, and the fixed sleeve 401 is coaxially sleeved on the outer periphery of the screw nut 304 and fixedly connected to the screw nut 304.

[0057] Preferably, the brush 402 is a soft plastic brush.

[0058] The length of the brush 402 is greater than the length of the brush cover 401. Preferably, the length of the brush cover 401 is 1 / 4 of the length of the brush 402. The top surface of the brush 402 is flush with the top surface of the brush cover 401, so the lower part of the brush 402 is not supported by the fixed cover 401. Since the duckbill is an inverted cone that is wide at the top and narrow at the bottom, the above-mentioned arrangement of the brush 402 and the brush cover 401 helps the bottom of the brush 402 to shrink along the shape of the inner wall of the duckbill 10 when the brush 402 enters the duckbill 10, so as to better fit the inner wall of the duckbill 0 and achieve a better impurity cleaning effect.

[0059] The transplanting mechanism of this embodiment only needs to add a cleaning mechanism on the basis of the existing duckbill type transplanting device, and the modification is simple and convenient, and the improvement cost is low.

[0060] Example 2

[0061] The present embodiment provides a working method of the transplanting mechanism capable of real-time cleaning of duckbills as described in Embodiment 1: when working, tobacco seedlings are manually placed into the seedling throwing mechanism 7, and the seedling throwing port of the seedling throwing mechanism 7 rotates to throw the tobacco seedlings into the bottom duckbills 10 through the seedling throwing device 8. When the duckbills 10 rotate to the bottom, the tobacco seedlings are transplanted into the soil. When the cleaning mechanism is not working, the brush assembly 4 is at the top dead center (its highest point), that is, the crank 501 is also at the most original position, and the multiple duckbills 10 of the eccentric disc duckbills transplanting mechanism 9 rotate along the circumference. When the duckbills 10 to be cleaned rotate to the cleaning station directly below the cleaning mechanism, the photoelectric proximity switch 11 generates an electrical signal and transmits To the controller 201 in the electric control system 2, the controller 201 transmits the electrical signal to the driver 202, and the driver 202 transmits the action signal to the servo motor 6. After receiving the signal command, the servo motor 6 starts to rotate, and is connected to the connecting rod 502 through the crank 501 to transmit the power to the screw nut 304 through the slip ring 503 and the bearing 504. The crank 501 starts to rotate from the original point to drive the screw nut 304 to rotate along a straight line from the top dead center to the bottom dead center. The process of reaching the bottom dead center is the process of the brush assembly 4 entering the duckbill 10. In this process, the brush 402 cleans the impurities on the inner wall of the duckbill 10 through rotation in the duckbill 10. After the screw nut 304 reaches the bottom dead center, the crank 501 continues to rotate to drive the screw nut 304 to rotate upward in the opposite direction until it reaches the top dead center and stops. At this time, the crank 501 returns to the original position. At this time, the impurity cleaning device for the inner wall of the duckbill completes a working cycle and waits for the next electrical signal of the photoelectric proximity switch 11.

[0062] The duckbill after cleaning continues to rotate to the bottom of the seedling placing device 8 to receive the tobacco seedlings dropped from the seedling placing device 8. In the transplanting mechanism of this embodiment, the duckbill 10 has been cleaned by the cleaning mechanism before seedling placing. The transplanting mechanism cooperates with the duckbill type transfer machine, and follows the order of cleaning first and then seedling placing, so that each duckbill 10 can always ensure that there are no impurities on its inner wall before transplanting into the soil, and the planting effect of the tobacco seedlings is guaranteed.

[0063] The transplanting mechanism and working method of this embodiment can clean the soil and impurities adhering to the inner wall of the duckbill 10 in real time, so as to ensure that the duckbill 10 can maintain the efficient operation of pot seedling transplanting during long-term work. The transplanting mechanism of this embodiment allows the operator to manually clean the duckbill of the transplanter without stopping the machine, thereby saving time and labor costs. By cleaning the soil and impurities on the inner wall of the duckbill in real time, not only the working efficiency of the transplanter is improved, but also the risk of failure caused by impurity accumulation can be reduced. The structure of the mechanism of this embodiment is simple and reliable, and it can operate stably and work in coordination with the transplanter, so that it can continue to work for a long time without affecting production efficiency. In addition, since the duckbill transplanting mechanism needs to work continuously in a cycle or the duckbill transplanting device occupies a large space when working, its duckbill is difficult to be cleaned immediately. Therefore, another advantage of this embodiment is that the space utilization rate is high. Due to the use of the structural mode of combining its crank connecting rod mechanism with the ball screw assembly, the device has a smaller action space and can greatly meet the duckbill cleaning task. Finally, since the device is also equipped with an electronic control system, the movement of the mechanism is more precise. The application of photoelectric proximity switches and encoders can provide more timely feedback on the working conditions of the duckbill transplanting mechanism.

[0065] This embodiment provides a transplanter, which is provided with the transplanting mechanism capable of cleaning the duckbill in real time as described in Embodiment 1. The remaining structure of the transplanter can adopt the existing technology and will not be described in detail here.

For those skilled in the art, the present application may have various modifications and variations.
