Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of agricultural equipment, especially relates to an equal-interval transplanting machine. BACKGROUND

[0002] In agricultural production, seedling transplanting is one of the key links to realize efficient planting. As an important agricultural machinery, seedling transplanting machine can significantly improve the transplanting efficiency and reduce the labor intensity. However, the existing seedling transplanting machine has some deficiencies in the adjustment of the transplanting mechanism.

[0003] At present, each group of transplanting mechanisms of the seedling transplanting machine can be longitudinally adjusted on the rack, and the distance between the adjacent transplanting mechanisms is adjusted to meet the requirements of different seedling planting distances and adapt to the needs of different sizes of fields. To some extent, this longitudinal adjustment function improves the versatility and flexibility of the transplanting machine. In order to ensure the good growth of the seedlings after planting, the distance between the plants in the longitudinal direction needs to be consistent, so the distance between the adjacent transplanting mechanisms after adjustment must also be the same.

[0004] However, the longitudinal adjustment mode of the transplanting mechanism in the prior art has obvious defects. At present, the longitudinal distance adjustment of the transplanting mechanism mainly relies on manual adjustment one by one, which is not only difficult to operate, but also difficult to ensure the adjustment accuracy. Since the position of each transplanting mechanism after adjustment is controlled manually, the adjustment error is large, which may lead to uneven horizontal distance between the seedlings after transplanting, thereby affecting the growth of the seedlings and the final yield. In addition, the efficiency of manual control adjustment is low, which is difficult to meet the needs of large-scale agricultural production. INVENTION CONTENTS

[0068] Powered traction equipment pulls transplanters across fields, planting seedlings in rows in the soil. Tractors are typically used as the powered traction equipment.

[0069] like Figures 1 to 8 As shown in an illustrative embodiment of the equal-spacing transplanter of this utility model, the equal-spacing transplanter includes a frame 200, a planting mechanism 300, a seedling feeding mechanism 400, and a spacing adjustment mechanism 500.

[0070] The vehicle frame 200 is provided with wheels 201, and the power traction device 100 is connected to the vehicle frame 200. The planting mechanism 300 and the seedling throwing mechanism 400 are both arranged on the vehicle frame 200, and the seedling throwing mechanisms 400 are arranged at equal intervals along the longitudinal direction of the vehicle frame 200, and the number of the planting mechanisms 300 is the same as that of the seedling throwing mechanisms 400, so that each seedling throwing mechanism 400 is provided with a corresponding planting mechanism 300 below. The planting mechanism 300 and the seedling throwing mechanism 400 are both drivingly connected to the power traction device 100. The vehicle frame 200 is provided with a seat 202 and a seedling tray 203 for the operator to sit on and place the seedlings.

[0071] The power traction device 100 drags the vehicle frame 200 to move forward in the field, and the operator throws the seedlings into the seedling throwing mechanisms 400. Under the driving of the power traction device 100, the seedling throwing mechanisms 400 throw the seedlings into the planting mechanisms 300 below one by one. Under the driving of the power traction device 100, the planting mechanisms 300 plant the seedlings into the soil along the direction of travel one by one. Finally, with the movement of the transplanting machine, the planting of multiple rows of seedlings in the field is completed at the same time.

[0072] In order to adjust the planting interval of the adjacent two rows, the planting mechanism 300 and the seedling throwing mechanism 400 are both slidingly arranged on the vehicle frame 200, so that both of them can move longitudinally on the vehicle frame 200. At the same time, in order to ensure that the planting mechanism 300 and the seedling throwing mechanism 400 are aligned, so that the seedlings thrown by the seedling throwing mechanism 400 can fall into the corresponding planting mechanism 300, the planting mechanism 300 and the seedling throwing mechanism 400 are connected through the synchronous connecting frame 204 to form a planting unit, so that the movement of the two in the longitudinal direction is synchronous.

[0073] The seedling throwing mechanisms 400 are all connected to the interval adjusting mechanism 500, and the interval adjusting mechanism 500 includes multiple groups of transmission adjusting assemblies 500A. The adjacent seedling throwing mechanisms 400 are connected through the transmission adjusting assemblies 500A, and the number of the transmission adjusting assemblies 500A is one less than that of the seedling throwing mechanisms 400.

[0074] As Figure 4As shown, the transmission adjusting assembly 500A includes two first transmission links 501 and two second transmission links 502. The transmission adjusting assembly 500A connects two seed dropping mechanisms 400, the two first transmission links 501 are both hinged at the same point of one of the seed dropping mechanisms 400, the two second transmission links 502 are both hinged at the same point of the other seed dropping mechanism 400, and the two first transmission links 501 are hinged with the two second transmission links 502 respectively, so that the two first transmission links 501 and the two second transmission links 502 of the transmission adjusting assembly 500A form a parallelogram linkage between the two seed dropping mechanisms 400. The first transmission link 501 and the second transmission link 502 in the transmission adjusting assembly 500A have the same length, so that the four transmission links in the transmission adjusting assembly 500A have the same length. For the two adjacent transmission adjusting assemblies 500A, one first transmission link 501 on one side of one of the transmission adjusting assemblies 500A is located on the same line with one second transmission link 502 on the other side of the adjacent transmission adjusting assembly 500A, and is fixedly connected at the same hinge point.

[0075] The transmission adjusting assemblies 500A on both sides of the seed dropping mechanism 400 are hinged at the same point of the seed dropping mechanism 400, and the adjacent seed dropping mechanisms 400 have the same spacing, so that the transmission links of all the transmission adjusting assemblies 500A have the same length. Further, since the two transmission links of the adjacent transmission adjusting assemblies 500A are fixedly connected at the same line and the same hinge point, when the seed dropping mechanism 400 is moved longitudinally to change its longitudinal spacing, the adjacent transmission adjusting assemblies 500A are linked simultaneously, and the swing angle of the transmission link in each transmission adjusting assembly 500A remains the same. Since all the transmission links have the same length, the width of each transmission adjusting assembly 500A in the longitudinal direction remains the same, and the spacing of the seed dropping mechanisms 400 remains the same. Since the aligned seed dropping mechanisms 400 and the planting mechanisms 300 form a planting unit, the spacing of the seed dropping mechanisms 400 remains the same after the spacing adjustment, so that the spacing of the adjacent final units also remains the same after the spacing adjustment.

[0076] When the spacing of each seed dropping mechanism 400 is adjusted, only one seed dropping mechanism 400 at one end in the longitudinal direction is fixed, and the other seed dropping mechanism 400 is slid, or both seed dropping mechanisms 400 are slid simultaneously, so that the spacing of the adjacent planting units is adjusted and remains the same, and the spacing adjustment operation is simple.

[0077] In the above exemplary embodiment, the spacing adjustment mechanism 500 keeps the spacing between the adjacent spacing transplanters 400 unchanged when the spacing transplanters 400 move longitudinally in linkage, and the operation is simple, the spacing control is easy, and the adjustment efficiency is high; the synchronization connecting frame 204 connects the spacing transplanters 400 and the transplanting mechanism 300, so that the spacing transplanters 400 and the transplanting mechanism 300 can move longitudinally in synchronization, the alignment of the spacing transplanters 400 and the transplanting mechanism 300 is kept, and the smooth feeding of the seedlings from the spacing transplanters 400 to the transplanting mechanism 300 for transplanting is ensured, thereby solving the problems of the current spacing transplanter adjustment mode, such as complicated operation, difficult precision control, and low adjustment efficiency.

[0078] In some embodiments, the fixedly connected first transmission connecting rod 501 and the second transmission connecting rod 502 are integrally connected on the same straight line. The structure design adopts the same connecting rod, which is divided into the first transmission connecting rod 501 of one transmission adjustment assembly 500A and the second transmission connecting rod 502 of the adjacent other transmission adjustment assembly 500A as the boundary of the hinge point, thereby reducing the number of components of the spacing adjustment mechanism 500, simplifying the structure, and reducing the assembly difficulty.

[0079] In some embodiments, as shown in Figure 5 the spacing transplanter further comprises an adjustment driving mechanism 600, and the adjustment driving mechanism 600 comprises an adjustment driving shaft 601 and an adjustment driving seat 602.

[0080] The adjustment driving shaft 601 is arranged on the vehicle frame 200 and connected with the power traction device 100, so as to rotate on the vehicle frame 200 under the driving of the power traction device 100. The adjustment driving seat 602 is provided with two adjustment driving seats 602, and the two adjustment driving seats 602 are arranged on the two synchronization connecting frames 204 at the two ends in the longitudinal direction. The two ends of the adjustment driving shaft 601 are respectively provided with a first external thread and a second external thread, the adjustment driving seat 602 is provided with a threaded hole, the adjustment driving shaft 601 passes through the two adjustment driving seats 602 through the threaded hole, and the adjustment driving shaft 601 is threadedly connected with the threaded hole of one adjustment driving seat 602 through the first external thread, and the adjustment driving seat 602 is threadedly connected with the threaded hole of the other adjustment driving seat 602 through the second external thread.

[0081] The adjustment driving shaft 601 and the adjustment driving seat 602 constitute a lead screw mechanism through the threaded connection. Since the first external thread and the second external thread have opposite screw directions, when the adjustment driving shaft 601 rotates under the driving, the two adjustment driving seats 602 at the two ends in the longitudinal direction move towards each other or move away from each other, so as to adjust the spacing between the two groups of planting units at the two ends in the longitudinal direction; since each spacing transplanter 400 moves longitudinally in linkage through the spacing adjustment mechanism 500, the change of the spacing between the two planting units at the two ends in the longitudinal direction causes the spacing between the adjacent planting units to change, thereby realizing the driving of the spacing adjustment between the adjacent planting units.

[0082] The driving for spacing adjustment through the screw rod structure does not need to fix one planting unit at one end in the longitudinal direction, and the adjustment can be realized by synchronous movement of both ends, and the structure for realizing the adjustment is simpler. Meanwhile, after the spacing adjustment, the planting units can be kept symmetrical left and right in the moving direction of the vehicle frame 200, so as to avoid that the planting units are all deviated to one side of the vehicle frame 200, resulting in unstable center of gravity.

[0083] In some embodiments, the vehicle frame 200 is provided with a clutch 700, an input shaft of the clutch 700 is connected with the power traction device 100, and an output shaft of the clutch 700 is drivingly connected with the adjustment driving shaft 601. When the spacing adjustment is performed, the clutch 700 connects the transmission between the input shaft and the output shaft, the power traction device 100 drives the adjustment driving shaft 601 to rotate through the engaged clutch 700, the spacing adjustment between the two groups of planting units at the two ends in the longitudinal direction is realized, the spacing adjustment between the adjacent planting units is realized, and the spacing is kept the same. After the spacing adjustment is completed, the clutch 700 disconnects the transmission between the input shaft and the output shaft, and the adjustment driving shaft 601 loses the driving and keeps fixed. The structure design makes the power input of the adjustment driving mechanism 600 be able to be connected or interrupted, so that the power traction device 100 can stop the spacing adjustment without stopping, and the operation is convenient.

[0084] In some embodiments, as shown in Figure 6 The seed dropping mechanism 400 includes a seed dropping seat 401, a fixed disc 402, a rotating disc 403, a seed storage pipe 404 and a seed outlet pipe 405.

[0085] The seed dropping seat 401 is slidingly installed on the vehicle frame 200, so that the seed dropping mechanism 400 as a whole can move in the longitudinal direction. The fixed disc 402 is fixedly installed on the seed dropping seat 401. The rotating disc 403 is rotatably installed on the seed dropping seat 401 and is drivingly connected with the power traction device 100. The rotating disc 403 is coaxially arranged above the fixed disc 402. The seed storage pipe 404 is axially installed on the rotating disc 403; a plurality of seed storage pipes 404 are equally spaced on the circumference concentric with the rotating disc 403; and the lower end of the seed storage pipe 404 penetrates the rotating disc 403. The seed outlet pipe 405 is fixedly installed at the top end of the fixed disc 402 and is connected with the through hole correspondingly provided on the fixed disc 402. The seed outlet pipe 405 is coaxially aligned with one of the seed storage pipes 404.

[0086] The operator places seedlings into the various seedling storage tubes 404, with the bottom of the seedlings extending downwards from the storage tubes 404 and resting on the fixed plate 402. Driven by the power traction device 100, the fixed plate 402 rotates, and the seedling storage tubes 404 rotate accordingly. The bottom of the seedlings slides on the fixed plate 402. When the seedling storage tube 404 containing the seedlings aligns with the seedling emergence tube 405, the seedlings lose the support of the fixed plate 402 and fall into the seedling emergence tube 405. The seedlings are then transported through the seedling emergence tube 405 to the planting mechanism 300, where they are planted in the soil.

[0087] This structural design allows multiple seedlings to wait in the seedling feeding mechanism 400 for delivery to the planting mechanism 300, ensuring the continuous delivery of seedlings to the planting mechanism 300 and guaranteeing the continuity of planting operations.

[0088] In some embodiments, such as Figures 4 to 6 As shown, a seedling-feeding drive shaft 406 is mounted on the frame 200, and the seedling-feeding drive shaft 406 is connected to the power traction device 100. A seedling-feeding machine base 401 is equipped with a meshing drive gear 407 and a driven gear (not shown in the attached figure), and the driven gear is connected to the rotating shaft of the rotating disk 403. The seedling-feeding drive shaft 406 is arranged longitudinally, and the drive gears 407 are all sleeved on the seedling-feeding drive shaft 406 through provided drive holes, so that the seedling-feeding drive shaft 406 drives the drive gears 407 to rotate, and the drive gears 407 can slide longitudinally on the seedling-feeding drive shaft 406.

[0089] The seedling feeding drive shaft 406 extends longitudinally through each seedling feeding machine base 401, and the drive gear 407 in each seedling feeding machine base 401 is sleeved onto the seedling feeding drive shaft 406. The seedling feeding drive shaft 406 has cross-sections on one or more sides of its outer wall, with the cross-sections axially aligned; or the seedling feeding drive shaft 406 has a polygonal cross-section; or the seedling feeding drive shaft 406 has a protruding transmission key, with the transmission key axially aligned. The drive hole of the drive gear 407 has the same cross-sectional shape as the seedling feeding drive shaft 406, allowing the drive gear 407 to move axially along the seedling feeding drive shaft 406 when sleeved on it, while simultaneously driving the drive gear 407 to rotate. The power traction device 100 drives the seedling feeding drive shaft 406 to rotate, the seedling feeding drive shaft 406 drives the drive gear 407 to rotate, the driven gear meshing with the drive gear 407 rotates, driving the rotating disk 403 to rotate, so that each seedling storage tube 404 is aligned with the seedling outlet tube 405 one by one, and the seedling feeding mechanism 400 is driven to feed the seedlings one by one.

[0090] The active gear 407 cooperates with the seedling throwing driving shaft 406 to enable the seedling throwing seat 401 to move longitudinally along the seedling throwing driving shaft 406, so that the seedling throwing seat 401 is slidably installed on the seedling throwing driving shaft 406 in the longitudinal direction of the machine frame, thereby enabling the seedling throwing mechanism 400 to move longitudinally while being capable of being driven by the power traction device 100.

[0091] In some embodiments, as shown in Figure 7 The planting mechanism 300 includes a planting seat 301, a planting turntable 302, a support disc 303, a duckbill opener 304, and a support connecting rod 305.

[0092] The planting seat 301 is slidably installed on the vehicle frame 200 and can move longitudinally; the planting turntable 302 is rotatably installed on the planting seat 301 and is drivingly connected to the power traction device 100. The support disc 303 is rotatably installed on the planting base and is eccentrically arranged relative to the planting turntable 302. The duckbill opener 304 is hingedly connected to the planting turntable 302 and is arranged at equal intervals along the coaxial center of the planting turntable 302. The support connecting rod 305 is the same in number as the duckbill openers 304; one end of the support connecting rod 305 is fixedly connected to the duckbill opener 304, and the other end is hingedly connected to the support disc 303; the hinged points of the support connecting rod 305 on the support disc 303 are located on the same circle coaxial with the support disc 303, so as to keep the support connecting rods 305 parallel to each other. The connecting line between the centers of the planting turntable 302 and the support disc 303 is parallel to each support connecting rod 305, thereby forming a parallelogram connecting rod structure to keep each support connecting rod 305 parallel when the planting turntable 302 and the support disc 303 rotate.

[0093] The power traction device 100 drives the planting turntable 302 to rotate, and each duckbill opener 304 rotates accordingly. When the duckbill opener 304 rotates to the upper part of the planting turntable 302, it is located below the seedling throwing mechanism 400 and is aligned with the seedling outlet pipe 405 of the seedling throwing mechanism 400; at the same time, the seedling storage pipe 404 containing seedlings in the seedling throwing mechanism 400 is aligned with the seedling outlet pipe 405, the seedlings are separated from the seedling storage pipe 404 and enter the seedling outlet pipe 405, and then fall into the duckbill opener 304. When the duckbill opener 304 containing seedlings rotates to the bottom of the planting turntable 302, the duckbill opener 304 penetrates into the soil and opens downward, opens a planting trench in the soil, and makes the seedlings fall into the planting trench through the opened duckbill opener 304, fills the planting trench, and covers the roots of the seedlings, i.e., completes the planting of the seedlings.

[0094] Since the open end of the duckbill opener 304 needs to be kept upward and the pointed end needs to be kept downward, the duckbill opener 304 is hinged to the planting turntable 302; during the rotation of the planting turntable 302, the support disc 303 is driven by the support connecting rods 305, the support connecting rods 305 are all parallel, and the duckbill openers 304 corresponding to the support connecting rods 305 are kept in a fixed posture, that is, the open end is always kept upward and the pointed end is always kept downward, so that the seedlings are prevented from falling out, and the duckbill opener 304 can smoothly penetrate into the soil.

[0095] In order to ensure that the planting mechanism is longitudinally moved and each planting turntable 302 is driven, the planting turntable 302 is arranged on a planting driving shaft with a polygonal cross section, the same driving mode as the seedling throwing driving shaft is adopted to drive the driving gear, so that the planting turntable 302 can be axially moved on the planting driving shaft to realize the longitudinal movement of the planting mechanism, and the planting driving shaft can drive the planting turntable 302 to rotate, and the power traction equipment 100 drives the planting driving shaft.

[0096] In some embodiments, as shown in Figures 7 to 8 two planting turntables 302 are coaxially arranged, and the duckbill openers 304 are located between the two planting turntables 302.

[0097] The duckbill opener 304 includes a ditching support 3041, a seedling receiving pipe 3042, a duckbill piece 3043 and a torsion spring 3044. The ditching support 3041 has two and is fixedly connected to the adjacent planting turntable 302. The seedling receiving pipe 3042 is provided with a ditching shaft 3045 on both sides; the two ditching shafts 3045 are coaxially arranged and are respectively rotatably installed on the adjacent ditching supports 3041; one ditching shaft 3045 is fixedly connected to the adjacent support connecting rod 305. The duckbill piece 3043 has two and is hingedly connected to the two ditching shafts 3045. The torsion spring 3044 is connected to the two duckbill pieces 3043 at both ends. The duckbill piece 3043 is provided with a driving guide wheel 3046 at the top end, and the ditching support 3041 is provided with a driving protrusion 3047 on the side close to the seedling receiving pipe 3042.

[0098] Since the two ditching supports 3041 are fixedly installed, the duckbill opener 304 is hinged to the planting turntable 302 through the connection of the two sides of the ditching shaft 3045 and the ditching support 3041. The seedling receiving pipe 3042 is vertically arranged, and the ports are located at the upper and lower ends, and the duckbill opener 304 is put into the seedling receiving pipe 3042 through the top end port. Under the pulling of the torsion spring 3044, the two duckbill pieces 3043 are combined at the bottom sharp part, and the seedlings falling into the seedling receiving pipe 3042 are supported.

[0099] Since the duckbill opener 304 keeps vertical as the planting turntable 302 rotates, the seedling receiving tube 3042 keeps vertical, and the two ditching supports 3041 on both sides of the seedling receiving tube 3042 rotate relative to the seedling receiving tube 3042. When a duckbill opener 304 rotates to the bottom end of the planting turntable 302 and penetrates into the soil, the driving protrusion 3047 rotates to the position aligned with the driving guide wheel 3046, so that the driving guide wheel 3046 rolls on the driving protrusion 3047, the driving protrusion 3047 pushes the driving guide wheel 3046 to move towards the seedling receiving tube 3042, overcomes the elastic force of the torsional spring 3044, so that the top of the two duckbill pieces 3043 are close to each other, and the bottom of the two duckbill pieces 3043 are far away from each other, thereby opening the bottom sharp parts of the two duckbill pieces 3043, and the seedling falls into the soil. When the duckbill opener 304 further rotates to rise and separate from the soil, the driving protrusion 3047 leaves the driving guide wheel 3046, and the torsional spring 3044 pulls the bottom sharp parts of the two duckbill pieces 3043 to combine, so as to put the seedling again. In order to ensure that the driving guide wheel 3046 rolls smoothly to the driving protrusion 3047, the edges on both sides of the driving protrusion 3047 are smoothly transitioned.

[0100] The structure design enables the duckbill opener 304 to automatically perform ditching and planting one by one, and the structure is compact and the operation efficiency is high.

[0101] In some embodiments, the vehicle frame 200 is longitudinally provided with an adjusting guide rail, which includes a first adjusting guide rail 205 and a second adjusting guide rail 206. The first adjusting guide rail 205 is located directly below the seedling throwing mechanism 400, and the second adjusting guide rail 206 is located directly above the planting mechanism 300. The synchronous connecting frame 204 is slidingly installed on the first adjusting guide rail 205 and the second adjusting guide rail 206.

[0102] Through the sliding of the synchronous connecting frame 204 on the two adjusting guide rails, the seedling throwing mechanism 400 and the planting mechanism 300 are slidingly installed on the vehicle frame 200. Under the guidance of the two adjusting guide rails, the synchronous connecting frame 204 not only slides smoothly, but also is stably installed. The first adjusting guide rail 205 supports the seedling throwing mechanism 400 below, improving the smoothness of the longitudinal sliding of the seedling throwing mechanism 400 and the stability of the installation of the seedling throwing mechanism 400. The second adjusting guide rail 206 suspends the planting mechanism 300 above, not only improving the smoothness of the longitudinal sliding, but also enabling the planting mechanism base 301 of the planting mechanism 300 to be connected to the synchronous connecting frame 204 above to realize sliding installation, without the need to set a guide rail structure at a lower position to realize sliding installation.

[0103] In some embodiments, the equidistance transplanter further comprises a plurality of covering devices 800, the number of the covering devices 800 is same as the number of the planting mechanisms 300, and each of the covering devices 800 is located at the back side of a corresponding planting mechanism 300. The covering device 800 is a roller with two conical surfaces, so that after the seedling is planted into the soil, the soil on both sides of the seedling is backfilled into the planting groove by rolling, the root of the seedling is buried, and the planting of the seedling is completed.

[0104] The chain wheel transmission assembly is installed on the frame 200, and the chain wheel transmission assembly comprises a plurality of transmission shafts, a plurality of gears and a plurality of chains. The connection mode of the chain wheel transmission assembly with the planting mechanism 300, the seedling throwing mechanism 400 and the adjusting driving mechanism 600 is prior art. The output shaft of the power traction device 100 is connected to a speed reducer installed on the frame 200, and the transmission shafts of the chain wheel transmission assembly are installed on the speed reducer, so that the power traction device 100 drives the transmission shafts of the chain wheel transmission assembly to rotate through the speed reducer, and the change of the rotation direction is realized. The gears are installed on the transmission shafts and the driving shafts, and are transmitted to each other through the chains. When the clutch is installed, one of the transmission shafts is divided into two sections, one section is connected to the input shaft of the clutch, and the other section is connected to the output shaft of the clutch. How the power traction device 100 drives the rotation of the driving shaft components in each mechanism through the chain wheel transmission assembly is prior art, and is not the point of the application.
