Description

Technical Field

[0001] This utility model relates to a seedling delivery mechanism for a backpack gasoline rice transplanter, belonging to the technical field of rice transplanting equipment. Background Technology

[0002] Rice transplanting is a planting method in which seedlings (usually potted seedlings with soil attached) are evenly scattered into the paddy field, replacing traditional hand or machine transplanting. The advantages of rice transplanting include significantly reduced labor and effort; its efficiency is 5-8 times that of hand transplanting, significantly reducing labor intensity and the risk of occupational diseases such as lumbar muscle strain caused by bending over. Simultaneously, transplanting seedlings with soil attached minimizes root damage, promotes rapid greening and early tillering, which is beneficial for increased yield. Furthermore, the short seedling raising cycle reduces the time spent in the seedbed, improving land utilization. It is also adaptable to various fields, including hilly areas and small plots, making it a highly efficient and practical simplified cultivation method. To address this, various rice transplanting devices have been developed within the industry. For example, Chinese utility model patent CN206821232U discloses a backpack-type pneumatic rice transplanter, specifically comprising a gasoline engine, a plunger pump, a transplanting nozzle, and a transplanter frame. The plunger pump is mounted on the base of the transplanter frame, and the gasoline engine is positioned above it. The gasoline engine drives the plunger pump to generate airflow. The air outlet of the plunger pump is connected to the transplanting nozzle via a pipe. The transplanting nozzle has an open structure and a handle with a control valve for controlling the gasoline engine's throttle. During transplanting, the operator first stacks the seedlings on the transplanting seat, and then another person moves the seedlings into the spray channel. The operator continuously presses the switch of the backpack-type gasoline rice transplanter to achieve uninterrupted transplanting until all the seedlings on the transplanting seat are transplanted. Another method is for the operator to throw the seedlings with their right hand, and after all the seedlings at the spray channel have been thrown, they stop and move the seedlings from the other side of the throwing platform. Therefore, if a seedling delivery mechanism is designed that allows a single person to simultaneously throw and move seedlings, the efficiency of seedling throwing operations can be significantly improved.

This invention involves placing seedlings in a storage basket and then using a pusher plate to push the seedlings towards the spray channel to achieve seedling delivery. A single person can perform both seedling delivery and delivery, significantly improving work efficiency.

[0004] The technical solution of this utility model: A seedling delivery mechanism for a backpack-type gasoline rice transplanter is connected to the backpack-type gasoline rice transplanter. The backpack-type gasoline rice transplanter includes a backpack, on which a gasoline generator and an air pump are installed. The gasoline generator and the air pump are connected by wiring. An air outlet pipe is provided on one side of the backpack, and the air outlet pipe is connected to the air outlet end of the air pump. The seedling delivery mechanism includes a seedling throwing seat connected to the air outlet pipe. The seedling throwing seat has a spray channel, which is connected to the air outlet end of the air outlet pipe. The seedling throwing seat has a moving groove. A push plate is slidably connected to the seedling throwing seat. The push plate passes through the moving groove and is connected to a handle seat. An operating handle is rotatably connected to the handle seat. A first guide groove is provided at the bottom front end of the seedling throwing seat. A hook plate is provided at the front end of the push plate, and the hook plate slides in cooperation with the first guide groove. An auxiliary support device is provided between the seedling throwing seat and the backpack.

[0005] The seedling delivery mechanism of the aforementioned backpack-type gasoline rice transplanter includes an auxiliary support device comprising a first support rod located on the right side of the backpack and a first connecting seat located on the left side of the backpack; the other end of the first support rod is fixedly connected to the rice transplanting seat; the first connecting seat is provided with a rotating groove, and a second support rod is rotatably connected within the rotating groove; a second connecting seat is provided on the left side of the rice transplanting seat, and the second connecting seat is provided with a locking groove, which engages with the outer end of the second support rod.

[0006] The aforementioned backpack-type gasoline rice transplanter's seedling delivery mechanism has a first through hole through the second connecting seat, which is connected to the locking groove; the outer end of the second support rod has a second through hole, which corresponds to the first through hole; a pin is provided on the first through hole, and the pin passes through the second through hole.

[0007] The aforementioned backpack-type gasoline rice transplanter's seedling delivery mechanism has a gripping arm on the air outlet pipe, and a control button on the gripping arm.

[0008] The aforementioned backpack-type gasoline rice transplanter's seedling delivery mechanism has a control box on the side of the air outlet pipe. The control box is connected to the control button, gasoline generator, and air pump via wiring.

[0009] The aforementioned backpack-type gasoline rice transplanter has a seedling delivery mechanism in which shoulder straps are symmetrically arranged on the backpack, and the shoulder straps are equipped with adjustment buckles.

[0010] The aforementioned backpack-type gasoline rice transplanter's seedling delivery mechanism includes a second guide groove located above the moving groove on the seedling throwing seat; the inner side of the push plate has a groove, and a roller is rotatably connected in the groove, with the roller cooperating with the second guide groove.

[0011] The aforementioned backpack-type gasoline rice transplanter has a seedling delivery mechanism in which the push plate has a ramp at the end facing the spray channel.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. In use, the operator puts on a backpack, secures the seedling throwing platform with the aid of an auxiliary support device, then places the seedlings in a pile on the platform, and starts the gasoline generator. After the generator generates electricity, the air pump operates, and the high-pressure gas produced is delivered through the exhaust pipe to the spray channel on the seedling throwing platform, providing power for the throwing. The operator holds the rotating handle connected to the handle base and pushes the push plate towards the spray channel. The push plate slides along the moving groove on the seedling throwing platform, while the hook plate slides in cooperation with the first guide groove to ensure smooth and precise movement of the push plate, preventing deviation. When the seedlings are pushed into the spray channel, the gas generated by the air pump is ejected from the spray channel through the exhaust pipe, and the seedlings are thrown out, achieving seedling throwing. If the seedlings pile up too high during the pushing process, they can be manually dispersed and leveled to ensure smooth subsequent pushing. Because the operating handle is rotatably connected to the handle base, it will hang down naturally when not in use, avoiding obstruction of the operator's limb movements and not affecting the comfort of the clothing. This allows operators to control the air pump with their right hand and move the seedlings with their left hand, thus reducing the number of workers and improving work efficiency.

[0014] 2. Before putting on the backpack, the second support plate can be rotated outward around the first connecting seat to create a wearing gap between the second support plate and the second connecting seat, allowing the operator to easily enter and put on the backpack through the gap. After putting it on, the second support plate is rotated back so that its outer end is inserted into the locking groove, and the second through hole is aligned with the first through hole. Then, the pin is inserted into the first and second through holes from above the second connecting seat to fix the second connecting seat and the second support rod. Subsequently, the first and second support rods support the rice transplanter, eliminating the need for the operator to lift the rice transplanter by hand. This not only completely frees up the operator's hands for more flexible operation but also avoids arm pain caused by prolonged hand support.

[0015] 3. The end of the pusher facing the spray channel is equipped with a ramp. During the pushing process, the ramp provides guidance for the seedlings, preventing the seedlings from getting stuck in the gap and causing blockage, and ensuring a smooth pushing process.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0021] Example: The seedling delivery mechanism of a backpack gasoline rice transplanter is configured as follows Figure 1-3 As shown, it is connected to a backpack-type gasoline rice transplanter. The backpack-type gasoline rice transplanter is a conventional machine available commercially. It includes a backpack 1 made of high-strength engineering plastic, which is lightweight, impact-resistant, and wear-resistant, able to withstand bumps and collisions during operation while reducing carrying weight. The backpack 1 is equipped with a gasoline generator 2 and an air pump 3, which are connected by wiring. The gasoline generator 22 uses a small four-stroke Honda GX120 gasoline engine with a displacement of 118cc and a power of 3.3HP, featuring fuel efficiency and low noise. The air pump 33 uses a GAST air pump. The rotary vane air pump 33 of the 1223 has a maximum pressure of 0.8 MPa, an exhaust volume of 35 L / min, and a compact size. The backpack 1 has an air outlet pipe 4 on one side, which is connected to the air outlet of the air pump 3. The seedling delivery mechanism includes a seedling throwing seat 5 connected to the air outlet pipe 4. The seedling throwing seat 55 is made of plastic and has a spray channel 6, which is connected to the air outlet of the air outlet pipe 4. The seedling throwing seat 5 has a moving groove 7. A push plate 8 is slidably connected to the seedling throwing seat 5. The push plate 8 is L-shaped. Figure 2As shown, the push plate 8 passes through the moving groove 7 and is connected to the handle seat 9. The contact part between the handle seat 9 and the seedling throwing seat 5 adopts a smooth arc transition design to avoid any sharp corners or protruding structures and reduce mechanical jamming. The part that mates with the moving groove 7 is designed as a rectangular convex strip, and the two sides of the convex strip are rounded to reduce the friction area with the inner wall of the moving groove 7. At the same time, the overall shape ensures the adaptability to the moving groove of the seedling throwing seat 5. Under the premise of ensuring sliding stability, unnecessary contact areas are minimized so that the handle seat 9 can slide smoothly in the moving groove. The operating handle 10 is rotatably connected to the handle seat 9. The operating handle 10 is covered with a rubber anti-slip sleeve, which is comfortable to hold and increases friction. It is connected to the handle seat 9 through a pivot and hangs down naturally when not in use to avoid interfering with operation. The end of the push plate 8 facing the spray channel 6 has a slope with an inclination angle of 30°. Its smooth surface can guide the seedlings to slide along the slope, prevent the seedlings from getting stuck, and ensure the continuity of pushing. Figure 3 As shown, the front bottom of the seedling throwing seat 5 is provided with a first guide groove 11; the front end of the push plate 8 is provided with a hook plate 12, the main body of the hook plate 12 is L-shaped, the main body surrounds the outer side of the front end of the seedling throwing seat 5, and the end of the main body is provided with an upwardly positioned vertical plate, which slides in cooperation with the first guide groove 11; an auxiliary support device 14 is provided between the seedling throwing seat 5 and the backpack 1. The seedling throwing seat 5 is provided with a second guide groove 13 located above the moving groove 7; the inner side of the push plate 8 is provided with a groove 20, and a roller 21 is rotatably connected in the groove 20, which cooperates with the second guide groove 13. In use, after the operator puts on the backpack 1, he fixes the seedling throwing seat 5 with the help of the auxiliary support device 14, then piles the seedlings into the seedling throwing seat 5, and then starts the gasoline generator 2; after the gasoline generator 2 generates electricity, the air pump 3 operates, and the high-pressure gas generated is transported through the air outlet pipe 4 to the spray channel 6 on the seedling throwing seat 5 to provide power for seedling throwing. The operator holds the rotating operating handle 10 on the handle base 9 and pushes the push plate 8 towards the spray channel 6. The push plate 8 slides along the moving groove 7 on the seedling throwing seat 5. At the same time, the roller 21 on the inner side of the push plate 8 rolls in the second guide groove 13 of the seedling throwing seat 5. This, combined with the sliding cooperation between the hook plate 12 and the first guide groove 11 at the bottom front end of the seedling throwing seat 5, forms a double guide, ensuring that the push plate 8 moves smoothly and accurately, avoiding deviation. The end of the push plate 8 facing the spray channel 6 has a ramp. During the pushing process, the ramp guides the seedlings, preventing them from getting stuck in the gaps and causing blockages, ensuring a smooth seedling pushing process. When the seedlings are pushed into the spray channel 6, the gas generated by the air pump 3 is ejected from the spray channel 6 through the air outlet pipe 4, and the seedlings are thrown out, realizing seedling throwing. If the seedlings pile up too high during the pushing process, they can be manually dispersed and leveled to ensure smooth subsequent pushing. Because the operating handle 10 is rotatably connected to the handle base 9, it will naturally droop when not in use, avoiding obstruction of the operator's limb movements and not affecting the comfort of wearing the equipment. Figure 2As shown, the auxiliary support device 14 includes a first support rod 30 located on the right side of the backpack 1 and a first connecting seat 31 located on the left side of the backpack 1; the first support plate is made of aluminum alloy; the other end of the first support rod 30 is fixedly connected to the seedling throwing seat 5; the first connecting seat 31 is provided with a rotating groove 32, and a second support rod 33 is rotatably connected in the rotating groove 32, the second support rod 33 being made of aluminum alloy; a second connecting seat 34 is provided on the left side of the seedling throwing seat 5, and a locking groove 35 is provided on the second connecting seat 34, the locking groove 35 engaging with the outer end of the second support rod 33. A first through hole 36 is provided through the second connecting seat 34, the first through hole 36 communicating with the locking groove 35; a second through hole 37 is provided at the outer end of the second support rod 33, the second through hole 37 corresponding to the first through hole 36; a pin 38 is provided on the first through hole 36, the pin 38 passing through the second through hole 37. First, the second support plate can be rotated outward around the first connecting seat 31 to create a wearing gap between the second support plate and the second connecting seat 34, allowing the operator to easily enter and put on the backpack 1. After putting it on, the second support plate is rotated back so that its outer end engages with the locking groove 35, and the second through hole 37 is aligned with the first through hole 36. Then, the pin 38 is inserted into the first through hole 36 and the second through hole 37 from above the second connecting seat 34, thus fixing the second connecting seat 34 to the second support rod 33. Subsequently, the first support rod 30 and the second support rod 33 support the rice transplanter 5, eliminating the need for the operator to hold the rice transplanter 5 by hand. This not only completely frees up the operator's hands for more flexible operation but also avoids arm pain caused by prolonged hand support. Figure 1 As shown, a gripping arm 15 is provided on the air outlet pipe 4, and a control button 16 is provided on the gripping arm 15. A control box 17 is provided on the side of the air outlet pipe 4. The control box 17 contains a Siemens S7-200 SMART PLC controller. The control box 17 is connected to the control button 16, the gasoline generator 2, and the air pump 3 via wiring. The operator can stabilize the equipment by gripping the gripping arm 15, and simultaneously control the output pressure of the air pump 3 by pressing the button, thus achieving precise rice transplanting control. Figure 1 As shown, the backpack 1 is symmetrically provided with shoulder straps 18. The shoulder straps 18 are made of high-strength nylon material and are provided with adjustment buckles 19. The length of the shoulder straps 18 can be adjusted according to the operator's body shape by adjusting the buckles 19.

[0022] Working principle:

[0023] The operator first adjusts the shoulder straps 18 on the backpack 1 to fit their own body, then uses the auxiliary support device 14 to fix the seedling throwing seat 5. The second support rod 33 is rotated around the first connecting seat 31 to create a wearing gap. After wearing, it is rotated back and its outer end is inserted into the locking groove 35 of the second connecting seat 34. It is then fixed by inserting a pin 38 through the through hole. The weight of the seedling throwing seat 5 is shared by the first support rod 30 and the second support rod 33, freeing up the operator's hands. During operation, seedlings are piled into the seedling throwing seat 5, and the gasoline generator 2 is started, which powers the air pump 3. The high-pressure gas generated by the air pump 3 is delivered to the spray channel 6 through the air outlet pipe 4. The operator holds the operating handle 10 and pushes the push plate 8. The push plate 8 slides along the moving groove 7, and the inner roller 21 rolls within the second guide groove 13. This, combined with the sliding of the hook plate 12 and the first guide groove 11, forms a double guide, ensuring smooth and precise movement. The slope at the end of the push plate 8 guides the seedlings to slide, preventing them from getting stuck in the gap. When the seedlings are pushed into the spray channel 6, high-pressure gas is ejected from the spray channel 6, which throws the seedlings out to complete the throwing process. During operation, the pressure of the air pump 3 can be adjusted by holding the control button 16 on the arm 15 and controlling the throwing force through the PLC controller in the control box 17.
