Description

Technical Field

[0001] The invention relates to the field of agricultural machinery, in particular to a high-efficiency full-automatic transplanting machine suitable for green and environmentally friendly paper pot seedlings. Background Art

[0002] Vegetable transplanting plays an important role in modern agriculture. It can shorten the crop growth cycle, avoid the impact of bad climate during the seedling stage, and improve yield and quality. Reasonable transplanting technology can improve field management, promote early maturity, increase the multiple cropping index, improve land utilization, and achieve efficient production. In recent years, paper pot seedlings have been widely used in modern agriculture due to their well-developed root system, low morbidity, environmental protection and degradability. Paper pots have good air permeability, and there is no need to pull seedlings during transplanting, which avoids damage to the root system and improves the survival rate. At the same time, because of its one-time use, it reduces the risk of disease transmission. The traditional hand-held chain paper pot transplanter completes crop transplanting through a chain conveyor system, but due to the fixed design of the paper chain, the plant spacing is difficult to adjust, resulting in dense plants, insufficient ventilation and light, and affecting the quality of crop growth. Existing equipment has deficiencies in plant spacing adjustment and operational flexibility, and cannot meet the planting needs of different crops. Summary of the invention

[0003] In view of the defects existing in the prior art, the purpose of the present invention is to provide an efficient and fully automatic transplanting machine suitable for green and environmentally friendly paper pot seedlings. The transplanting machine has added a cutting and seedling separation mechanism, breaking through the limitation of the paper chain length on the plant spacing. The cutting mechanism can accurately cut the paper chain and flexibly adjust the plant spacing. The seedling separation mechanism realizes fine planting, which significantly optimizes the functions of traditional transplanting machines, reduces material waste and operation complexity, and improves the adaptability and economic benefits of the equipment. The invention effectively solves the problem of unadjustable plant spacing, improves the flexibility of transplanting operations, reduces production costs, and improves economic benefits.

[0007] The pressing component is used to press the paper chain against the inner wall of the shell when the seedling paper pot positioning mechanism moves, so as to ensure that the seedling paper pot can be accurately introduced into the seedling paper pot positioning groove in the seedling paper pot positioning mechanism; at the same time, pressing the paper chain against the inner wall will provide a certain tension force to the paper, which is conducive to cutting by the cutting knife;

[0008] The planting distance of the seedling pots can be controlled by adjusting the movement speed of the seedling pot positioning mechanism relative to the housing;

[0009] The paper chain cutting device 2 is provided with a cutting knife capable of reciprocating periodic motion, which is used to cut the paper chain entering the seedling picking and separating device 1, and separate the seedling pots on the paper chain one by one; the cutting speed of the cutting knife is adapted to the movement speed of the seedling pot positioning mechanism;

[0010] The transmission device 3 is used to drive the seedling picking and separating device 1 and the paper chain cutting device 2;

[0011] The bionic furrow opener 405 is used to open furrows during operation;

[0012] The seedling guiding device is used to guide the paper chain with the seedling paper pot into the seedling picking and separating device.

[0013] On the basis of the above scheme,

[0014] The seedling pot positioning mechanism in the seedling separation and removal device 1 is connected to the drive shaft 204 and performs rotational motion relative to the housing;

[0015] Each of the pressing components is driven by a spring 104 , and the head of the pressing component is in contact with the inside of the housing under the elastic force of the spring 104 .

[0016] On the basis of the above scheme,

[0017] The paper chain cutting device 2 includes an incomplete gear 201 installed on a driving shaft 204, a closed-loop rack 202 meshing with the incomplete gear 201, and performing reciprocating periodic motion under the drive of the incomplete gear 201; a cutting knife is arranged at one end of the closed-loop rack 202, and can perform reciprocating periodic motion with the closed-loop rack 202 to cut the paper chain inside the seedling picking and separating device, and separate the seedling paper pots on the paper chain one by one.

[0018] On the basis of the above scheme,

[0019] The transmission device 3 is connected to the driving shaft 204 and is used to drive the movement of the seedling picking and separating device 1 and the paper chain cutting device 2; the transmission device is driven by the walking wheel 8 installed at the lower rear part of the frame 4.

[0020] On the basis of the above scheme,

[0021] The contour arm 504 is movably connected to the front part of the bracket 5, and a pair of soil covering wheels 6 with axles forming a certain angle are connected to the contour arm 504.

[0024] The efficient and fully automatic transplanting machine suitable for green and environmentally friendly paper pot seedlings of the present invention has the following beneficial effects:

[0025] (1) By adding a cutting mechanism and a seedling separation mechanism, the limitation of the paper chain length on the plant spacing in the traditional chain transplanter has been broken through, and the problem that the existing equipment cannot flexibly adjust the plant spacing has been solved. The paper chain cutting device uses the meshing movement of an incomplete gear and a closed-loop rack to drive the cutting knife to reciprocate and accurately cut the paper chain, thus achieving the adjustability of the plant spacing. At the same time, the seedling separation mechanism accurately transports a single paper pot, avoiding problems such as dense plants and insufficient ventilation caused by the close distance between paper pots, and optimizing the growth environment of crops.

[0026] (2) It can accurately adjust the plant spacing according to the needs of different crops, improve the efficiency of field management, avoid material waste, and reduce production costs. The automated cutting and seedling separation function reduces the dependence on manpower, improves the efficiency of transplanting, reduces the cost of manual transplanting, and is suitable for large-scale promotion and application. Through precise control of the paper chain, the equipment reduces damage to the paper pots caused by operational errors, extends the service life of the paper pots, and effectively reduces the cost of planting inputs.

[0027] (3) It has excellent ease of operation and can operate stably in various terrains without frequent equipment adjustments. Its transmission device has a compact structure and smooth power transmission, which enables the equipment to maintain efficient and stable performance during operation. It is suitable for the transplanting needs of various crops, improves the versatility and adaptability of the equipment, and can be used flexibly in different crop growth stages to facilitate the regulation of planting density. The soil cleaning device is supported by springs and can effectively remove the soil attached to the walking wheels, ensuring that the equipment is not affected by the soil during operation, further improving the practicality of the equipment.

[0028] (4) By reducing the loss of paper pots and unnecessary soil disturbance, it supports environmental protection and resource conservation, and plays a positive role in protecting soil ecology. The equipment improves transplanting efficiency and crop survival rate, supports the demand for increased grain production, meets the requirements of modern agriculture for high yield and high efficiency, and promotes the sustainable development of agriculture.

[0048] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0049] like Figure 1 As shown, a high-efficiency fully automatic transplanting machine suitable for green and environmentally friendly paper pot seedlings includes a seedling picking and separating device 1, a paper chain cutting device 2, a transmission device 3, a frame 4, a bracket 5, a soil covering mechanism 6, a spring soil cleaning device 7, walking wheels 8, and a seedling guide groove 9.

[0050] The structure of the efficient and fully automatic transplanter suitable for green and environmentally friendly paper pot seedlings is as follows: the adjustable height armrest 401 is connected to the frame 402 through a sleeve-type bolt fixing device, the walking wheels 8 are symmetrically installed on both sides of the frame through the front sprocket shaft 306, the front sprocket shaft 306 is synchronously connected to the walking wheels, the mudguard 701 is symmetrically installed on both sides of the frame through the front sprocket shaft, and a spring soil cleaning device 7 is installed at its end, the spring soil cleaning device 7 is composed of a mudguard 701, a spring 702, a hinge connector 703 and a soil cleaning piece 704, the soil cleaning piece 704 keeps a certain distance from the walking wheel 8, and is connected to the mudguard 701 through the hinge connector 703; the seedling placement plate 403 and the seedling guide groove 9 are located above the frame, the seedling outlet of the seedling guide groove is connected to the seedling protection cover 101, and the seedling protection cover is supported by the base The plate 502 is fixed, the base support plate is connected to the profiling bracket 503, the bracket is installed on the rear sprocket shaft through a supporting bearing, the upper end of the seedling drop tube 107 is tangent to the seedling protection cover, and is fixed by the bracket; the power transmission system is installed on the front sprocket shaft by the active sprocket 307, which is connected to the driven sprocket 304 on the rear sprocket shaft through a chain, and the rear sprocket shaft is equipped with an active bevel gear 303, which is vertically meshed with the driven bevel gear 302, and the power is transmitted to the drive shaft through the driven bevel gear, and the paper chain cutting device 2 and the seedling picking and separating device 1 are coaxially installed with the drive shaft 204; the profiling arm 504 is fixed on the bracket through the profiling bracket 503, and is connected to the soil covering pressure wheel 6, the two soil covering pressure wheels are at a certain angle, the handle 404 is fixed to one side of the frame, and the profiling furrow opener 405 is horizontally installed below the frame.

[0051] The working principle of the transplanter is as follows: when the transplanter is working, the seedling tray is first placed on the seedling tray bracket, the paper chain is pulled apart, and the first two paper pots are placed on the seedling separation turntable. The pulled apart paper chain is located in the seedling guide groove. As the transplanter moves forward, the bionic furrow opener starts to work and opens the sowing groove. The wheel rotates to transmit power to the front sprocket shaft, and then to the rear sprocket shaft through the chain, and then the power is transmitted to the connecting shaft through the bevel gear transmission. The connecting shaft drives the paper chain cutting device and the seedling picking and separating device at the same time. The seedling separation turntable rotates to feed the paper chain into the device, and the knife of the paper chain cutting device then reciprocates to accurately cut the paper chain. After cutting, the seedling separation turntable transmits the cut paper pot to the seedling drop tube mouth, and the paper pot falls into the groove through the seedling drop tube under the action of gravity. By controlling the forward speed of the transplanter, the planting spacing of the paper pots in the soil can be adjusted to meet the needs of different crops. Finally, the soil covering and pressing wheels moderately compact the soil above the seedlings, successfully completing the transplanting process.

[0052] like Figure 2 As shown, the seedling separation and removal device 1 includes: a seedling protection cover 101 (i.e., a housing), a flange 102, a spring mounting base 103, a spring 104, a spring top 105, a seedling separation tray 106 (i.e., a seedling pot positioning mechanism), a seedling drop tube 107, and a seedling separation tray driving wheel 108;

[0053] The flange 102 and the seedling separation plate driving wheel 108 are coaxially installed on the driving shaft 204, wherein the seedling separation plate driving wheel 108 and the driving shaft 204 are connected by a key to ensure the transmission of torque; the flange 102 is fixedly connected to the driving shaft 204 to ensure that the flange is firmly fixed on the shaft and easy to disassemble.

[0054] The flange 102 is fixedly connected with the seedling disc 106 through the limiting hole to ensure that the seedling disc and the flange are installed concentrically. The center of the seedling disc 106 is coaxial with the drive shaft 204, and 8 grooves are designed inside the disc body for installing the spring ejection mechanism.

[0055] The spring ejection mechanism (i.e., the pressing component) includes a spring mounting base 103, a spring 104, and a spring ejection head 105 (i.e., the head of the pressing component). The spring mounting base 103 is in direct contact with the seedling tray driving wheel 108 to provide stable support. The spring 104 is installed between the spring mounting base 103 and the spring ejection head 105 to form a compressible structure, and the top of the spring ejection head 105 is in contact with the inner wall of the seedling protection cover 101.

[0056] The seedling protection cover 101 is fixed on the bracket 5 through the limiting hole to ensure that it is stable and immovable during operation. The top of the seedling drop tube 107 is tangent to the bottom seedling outlet of the seedling protection cover 101, ensuring that the seedlings flow from the protection cover into the seedling drop tube smoothly. The bottom of the seedling drop tube 107 completely overlaps with the seedling outlet of the seedling protection cover 101, ensuring the docking accuracy when the seedlings pass through, and preventing jamming or seedling leakage.

[0057] Working principle: When the device is working, the drive shaft 204 starts to rotate, and the drive shaft directly drives the seedling disc drive wheel 108 to rotate through a key connection. The rotation of the drive wheel 108 transmits power to the seedling disc 106 through the flange 102 at the same time, and the flange 102 and the seedling disc 106 are fixedly connected through the limit hole. Therefore, the drive shaft and the flange act at the same time, driving the seedling disc 106 to rotate synchronously. As the seedling disc 106 rotates, the paper chain located on its periphery begins to move forward, and the paper pot gradually enters the multiple grooves designed on the seedling disc 106.

[0058] When the paper pot enters the slot of the seedling tray 106, the edge of the paper chain is pressed by the spring ejection mechanism. The spring ejection mechanism is composed of a spring mounting base 103, a spring 104 and a spring ejection head 105. During the rotation of the seedling tray 106, the spring ejection head 105 applies continuous pressure to the paper chain as the seedling tray rotates, firmly fixing it on the inner wall of the seedling protection cover 101. The purpose of this pressing action is to ensure that the paper chain does not slide or shift during the rotation process, and to ensure that the paper pot can be accurately introduced into the slot of the seedling tray 106, ready for subsequent operations.

[0059] When the seedling tray 106 continues to rotate, the paper chain cutting mechanism 2 cuts the paper chain. When the connection of the paper chain is transferred to the cutting position, the cutting mechanism acts synchronously to accurately cut the paper chain into independent paper pots.

[0060] The cut independent paper pot is supported by the groove on the seedling separation plate 106, and continues to move to the top of the seedling drop tube 107 as the seedling separation plate rotates. The upper end of the seedling drop tube 107 is aligned with the seedling outlet of the seedling protection cover 101 to ensure that the paper pot can smoothly enter the seedling drop tube. In this process, the paper pot slides down along the seedling drop tube by gravity, completing the entire seedling separation process.

[0061] Figure 3 As shown, the paper chain cutting device 2 includes an incomplete gear 201, a closed-loop rack 202, a disc cutting knife 203 and a driving shaft 204;

[0062] The incomplete gear 201 is fixed to the drive shaft 204 through a key connection and meshes with the closed-loop rack 202. The closed-loop rack 202 is installed along the slide rail at the bottom of the seedling protection cover 101 to ensure that the closed-loop rack 202 can perform linear motion in the slide rail. The disc cutter 203 is fixedly installed on the top of the closed-loop rack 202 through a bearing, and its cutting edge remains parallel to the blade inlet and outlet of the seedling protection cover 101. The incomplete gear 201 and the closed-loop rack 202 are in the same plane, and the slide rail provides guidance for the closed-loop rack so that it can move back and forth along a fixed path. The disc cutter 203 contacts the paper chain through the movement of the closed-loop rack 202, ensuring that the blade is aligned with the paper chain and accurately matches the blade inlet and outlet of the seedling protection cover 101.

[0063] Principle: During operation, the drive shaft 204 drives the incomplete gear 201 to rotate. When a part of the teeth of the incomplete gear 201 meshes with the closed-loop rack 202, the rack is driven to move forward along the slide rail (linear displacement). When the incomplete gear 201 rotates to the toothless section, the closed-loop rack 202 stops moving, and then when another part of the teeth of the gear meshes with the closed-loop rack 202 again, the rack is driven in the reverse direction and moves backward (reverse linear displacement). This periodic engagement and disengagement causes the closed-loop rack 202 to reciprocate linearly in the slide rail. The disc cutter 203 is fixed to the top of the closed-loop rack 202, and slides back and forth in the cutting groove of the seedling protection cover 101 through the reciprocating motion of the rack. The cutting groove is designed as a precise slit to guide the movement path of the cutting blade. Through the reciprocating motion of the disc cutter 203, the paper chain is accurately cut in the cutting groove, and the cutting process is coordinated with the rotation of the seedling separation plate 106 to avoid cutting the seedlings. The movement of the disc cutter 203 ensures that the paper chain can be neatly cut into independent paper pots. The closed-loop rack 202 is installed in the slide rail system at the bottom of the seedling protection cover 101. The slide rail provides precise guidance and restriction for the rack, ensuring smooth and non-deviation linear movement of the rack and preventing the rack from shaking left and right or derailing.

[0064] The disc cutting knife 203 described above is only a specific choice of the cutting knife. The cutting knife can also be selected as a flat-blade knife, a circular-blade knife with power drive, etc.

[0065] like Figure 4 As shown, the transmission device 3 includes a rear sprocket shaft 301, a driven bevel gear 302, a driving bevel gear 303, a rear sprocket 304, a chain 305, a front sprocket shaft 306, and a front sprocket 307;

[0066] The rear sprocket shaft 301 and the front sprocket shaft 306 are both mounted on the frame 4. The front sprocket shaft 306 is connected to the running wheel 8 through a flange to achieve power transmission. The front sprocket 307 is mounted at the front end of the front sprocket shaft 306 and is connected by a key to ensure that it can run smoothly. The chain 305, as a transmission medium, surrounds the front sprocket 307 and the rear sprocket 304, and transmits power from the front sprocket 307 to the rear sprocket 304 through the movement of the chain. The rear sprocket 304 is coaxially fixed on the rear sprocket shaft 301 with the driving bevel gear 303 to ensure that the two rotate synchronously. The driving bevel gear 303 is meshed with the driven bevel gear 302, and the two are installed in a vertical manner, so that the rotation of the rear sprocket shaft 301 can change the direction of power through the bevel gear set and transmit it to the drive shaft 204.

[0067] Principle: When working, the travel wheel 8 starts to rotate, and the rotation of the travel wheel transmits power to the front sprocket shaft 306. As the front sprocket shaft 306 rotates, the front sprocket 307 also rotates synchronously. The front sprocket 307 is connected to the rear sprocket 304 through the chain 305. The chain 305 starts to move under the drive of the front sprocket 307, and transmits the rotation power of the front sprocket to the rear sprocket 304. The rear sprocket 304 is coaxially fixed with the rear sprocket shaft 301. The rotation of the rear sprocket further transmits power through the rear sprocket shaft 301, driving the rear sprocket shaft 301 to rotate synchronously. The rotation of the rear sprocket shaft 301 directly drives the driving bevel gear 303 to rotate synchronously. The driving bevel gear 303 meshes with the driven bevel gear 302 through its helical teeth. Due to the design of the bevel gear set, the rotational motion of the driving bevel gear 303 is converted into vertical power transmission, thereby driving the driven bevel gear 302 to rotate. The driven bevel gear 302 is mounted on the driving shaft 204 , so the power is transmitted to the driving shaft 204 through the driven bevel gear; the rotation of the driving shaft 204 provides power for the subsequent mechanical parts.

[0068] like Figure 5 As shown, the frame 4 includes an adjustable height armrest 401, a main support 402, a seedling placement tray 403, a handle 404 and a bionic furrow opener 405. The main support 402 and the adjustable height armrest 401 are fixedly connected by a sleeve-type latch. The armrest 401 is designed as an inner tube, which is inserted into the outer tube of the main support 402. A plurality of positioning holes are reserved on the outer tube, each hole corresponding to a specific height position, so as to realize multi-stage height adjustment.

[0069] The seedling placement tray 403 is fixedly mounted above the main support 402 for placing seedlings. The handle 404 is mounted on the side of the main support 402 to facilitate operators to control and move the equipment. The bionic furrow opener 405 is located below the main support 402 and is used for furrowing during operation, ensuring that the equipment has versatility and stability when in use.

[0070] like Figure 6 As shown, the bracket 5 includes a support bearing 501, a support plate 502, a contour bracket 503, and a contour arm 504; the support bearing 501 is installed on the rear sprocket shaft 301, and plays the role of connecting the rear sprocket shaft and the contour bracket 503. The support bearing not only supports the rotation of the rear sprocket shaft, but also ensures the close connection between the bracket and the rear sprocket shaft, so that the power of the transmission system can be smoothly transmitted without affecting the stability of the contour structure. The support plate 502 is installed above the contour bracket 503, and is used to fix the seedling protection cover 101.

[0071] The contour support 503 is connected to the contour arm 504 by a hinge, and the contour arm 504 can rotate at the connection with the contour support. The rotation function of the contour arm enables it to make adaptive adjustments with the ups and downs of the terrain, ensuring that the equipment can remain stable even on uneven ground. Through the rotation of the contour arm, the equipment can automatically adjust the height and angle when the terrain changes, so that key components such as the seedling protection cover and the furrow opener are always kept in a suitable working position, ensuring the accuracy of seedling separation and furrow opening.

[0072] like Figure 7 As shown, the soil covering wheel 6 is mounted on the profiling arm 504, and the connection design of the profiling arm allows the soil covering wheel to maintain a specific angle, so that the soil is gathered to the middle when the equipment moves forward, ensuring uniform soil covering in the planting furrow. The soil covering wheel adopts an arc tire structure, which helps to avoid soil accumulation on the tire surface, thereby improving the rolling effect of the tire on various terrains. The profiling arm 504 is flexible and supported by the profiling bracket 503, so that the soil covering wheel can conform to the terrain and ensure the continuity and uniformity of the ground contact. At the connection point of the profiling bracket 503, the profiling arm can rotate vertically, so that the soil covering wheel can keep close to the ground even on rugged terrain. In addition, the support bearing 501 further enhances the stability of the equipment, so that the soil covering wheel can smoothly and evenly complete the soil covering operation under various terrain conditions.

[0073] like Figure 8 As shown, the spring soil cleaning device 7 includes a mud guard 701, a spring 702, a hinge connector 703 and a soil cleaning piece 704. The mud guard 701 is fixedly mounted on the main bracket 402 to block splashing soil. The soil cleaning piece 704 is connected to the mud guard 701 through the hinge connector 703 so that it can swing flexibly at the hinge. The spring 702 is installed between the soil cleaning piece 704 and the mud guard 701 to provide elastic support and buffering force.

[0074] During operation, the cleaning blade 704 maintains a small gap with the running wheel 8, and the cleaning blade is kept in a suitable position by the support force of the spring 702 to scrape off the dirt attached to the surface of the running wheel. When encountering resistance, the cleaning blade 704 rotates around the hinge connector 703, compressing the spring 702, and the elasticity of the spring 702 provides a restoring force, so that the cleaning blade quickly returns to its original position after removing the dirt. During the recovery process, the cleaning blade generates a small periodic vibration, which reduces the adhesion of dirt on the cleaning blade and improves the efficiency of cleaning.
