Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of agricultural machinery, and particularly relates to a potted rice blanket seedling cutting and throwing machine. BACKGROUND

[0002] There are three forms of planting rice, namely, direct seeding, transplanting and throwing. Direct seeding is simple and convenient, but has problems such as poor connection of crop rotation, more weeds and pests. Although the transplanting can solve the problems of poor connection of crop rotation and more weeds and pests to some extent, the transplanting machine has problems such as complex structure, high cost, less rows, low work efficiency, large damage of the seedling needle to the seedling blanket during the transplanting process, long green-up period and the like. The throwing of rice mainly throws potted rice seedlings, and since the potted seedlings have soil pots, the throwing does not damage the roots and the green-up is fast. However, the throwing machine for throwing potted rice seedlings needs to use special seedling trays for seedling, which leads to difficult loading and transportation of seedlings during the throwing and transplanting process, low production efficiency and high labor cost.

[0003] The potted blanket seedlings of rice have the advantages of fast green-up of potted rice seedlings and easy loading and transportation of rice blanket seedlings, and if the cutting and throwing efficiency of the potted blanket seedlings of rice can be improved through technical upgrading, this rice planting method has great superiority compared with direct seeding and transplanting, has a very promising market prospect, and the cutting and throwing of the potted blanket seedlings of rice will become the most mainstream rice planting method. However, the cutting and throwing of the potted blanket seedlings is a bottleneck, which restricts the development of the throwing machine.

[0004] In view of the above, there is an urgent need to provide a potted blanket seedling cutting and throwing machine for rice, which can reduce cutting damage and improve the survival rate of seedlings. SUMMARY

[0005] The present application belongs to the technical field of agricultural machinery, and particularly relates to a potted rice blanket seedling cutting and throwing machine.

[0006] The above object is achieved by the following technical solution: a paddy rice pot body blanket seedling cutting and throwing machine, comprising a rack and a conveying device, a cutting device, a blanket pressing device, a cutting device and a seedling guiding device arranged on the rack, the paddy rice pot body blanket seedling cutting and throwing machine is sequentially provided with a cutting station, a cutting station and a seedling throwing station along the conveying direction of the conveying device, the conveying device is used to convey seedlings through the cutting station, the cutting station and the seedling throwing station in sequence, the blanket pressing device and the cutting device are arranged in the cutting station, the blanket pressing device is used to press the paddy rice pot body blanket seedling, the cutting device cuts the paddy rice pot body blanket seedling into seedling strips, the cutting device is arranged in the cutting station and is used to cut the seedling strips into blocky seedlings, the cutting device comprises a cutting driving member, a cutting assembly, a transverse cutting guide and a cutting auxiliary assembly, the cutting assembly comprises a cutting knife, the cutting driving member is in transmission connection with the cutting assembly and is used to drive the cutting knife to rotate along a fixed rotating shaft, the cutting auxiliary assembly is used to cooperate with the cutting assembly to ensure that the cutting plane of the cutting knife is always perpendicular to the cutting surface of the paddy rice pot body blanket seedling, the transverse cutting guide is arranged at a predetermined position and is used to drive the cutting knife to move transversely on the cutting surface of the paddy rice pot body blanket seedling, and the seedling guiding device is arranged in the seedling throwing station and is used to group and throw the blocky seedlings.

[0007] Those skilled in the art should understand that the cutting surface herein is the plane where the paddy rice pot body blanket seedling is located; in the specific application process, the paddy rice pot body blanket seedling moves with the conveying device, sequentially flows through the cutting station, the cutting station and the seedling station, is pressed by the blanket pressing device, is cut into seedling strips by the cutting device, is cut by the cutting device, and finally the blocky seedlings are grouped and thrown by the seedling guiding device. In the cutting process of the cutting device, the cutting auxiliary assembly cooperates with the cutting assembly to ensure that the cutting plane of the cutting knife is always perpendicular to the cutting surface of the paddy rice pot body blanket seedling, to ensure the effect of vertical cutting, and at the same time the transverse cutting guide drives the cutting knife to move transversely on the cutting surface of the paddy rice pot body blanket seedling, so as to have the effect of horizontal cutting, and the combined action of the cutting knife during cutting is transverse oblique cutting, which can avoid cutting the stem of the seedling and improve the survival rate of the seedling.

[0008] Further, the cutting assembly further comprises a driving shaft, a cutting side plate and a cutting knife shaft set, the cutting knife shaft set comprises a center shaft and a cutting knife shaft, the cutting knife is arranged on the cutting knife shaft, the cutting knife shaft is sleeved on the center shaft, the cutting driving element is in transmission connection with the driving shaft, the two ends of the driving shaft are connected with the cutting side plates respectively, the two ends of the center shaft are installed on the cutting side plates through a rotating pair respectively, the cutting auxiliary assembly comprises an eccentric side plate, an auxiliary wheel and a connecting rod, the auxiliary wheel is arranged on the eccentric side plate, the auxiliary wheel is provided with a through hole, the driving shaft is in rotation connection with the rack through the through hole, one end of the center shaft is connected with one end of the connecting rod, the other end of the connecting rod is connected with the eccentric side plate through a connecting rod shaft, the eccentric side plate rotates around the center of the auxiliary wheel, the cutting side plate rotates around the center of the driving shaft, the center of the auxiliary wheel and the center of the driving shaft are spaced apart by a predetermined distance, and the center of the auxiliary wheel, the center of the driving shaft, the center of the cutting knife shaft and the center of the connecting rod shaft form a parallelogram in the same plane.

[0009] In this way, the eccentric side plate rotates around the center of the auxiliary wheel, the cutting side plate rotates around the center of the driving shaft, the eccentric distance between the center of the auxiliary wheel and the center of the driving shaft is L2, the distance between the center of the connecting rod shaft and the center of the cutting knife shaft E is the length of the connecting rod L1, L1 is equal to L2, and the distance between the center of the auxiliary wheel and the center of the connecting rod shaft is equal to the distance between the center of the driving shaft and the center of the cutting knife shaft. Therefore, the centers of the auxiliary wheel, the driving shaft, the connecting rod shaft and the cutting knife shaft form a parallelogram mechanism. Since the auxiliary wheel is fixedly installed on the cutting support through the eccentric wheel mounting plate, when the mechanism rotates with the center of the driving shaft as the fixed point, the cutting knife always rotates in the same posture.

[0010] Further, the cutting knife shaft set further comprises a transverse cutting cam and a reset element, the transverse cutting cam is provided with a ball head and a connecting hole, the center shaft is a hollow shaft, a guide groove is arranged on the center shaft in the axial direction, the reset element is sleeved on one end of the center shaft, and the transverse cutting cam is arranged on the other end of the center shaft, the transverse cutting cam is connected with the cutting knife shaft through a connecting element, the connecting element passes through the connecting hole and the guide groove, and the two sides of the reset element abut against the cutting knife shaft and the cutting side plate respectively. When the cutting knife shaft rotates to a predetermined position, the transverse cutting guide pushes the transverse cutting cam to move along the guide groove and drives the cutting knife shaft to move transversely, and the reset element is used to drive the cutting knife shaft to reset to the initial position when the transverse cutting guide has no force on the transverse cutting cam.

[0011] The cutting block driving member is preferably a cutting block motor, and the reset member is preferably a compression spring. In this way, the cutting block motor drives the driving shaft to rotate, the driving shaft drives the cutting block side plate to rotate, the cutting block side plate drives the cutting block shaft group to rotate, and the cutting block shaft group drives the cutting knife to move. When the cutting knife is in the initial position, the cutting knife is placed between the two seedlings under the action of the compression spring. When the cutting knife moves along the cutting knife rotation circle, the cutting knife enters the seedling mat from between the two seedlings. When the cutting knife tip contacts the seedling mat, the cutting knife is driven to move horizontally by the horizontal cutting guide. Under the action of the horizontal cutting cam, the cutting knife moves horizontally to the other side, so that the cutting knife moves horizontally while being vertically cut to achieve oblique cutting.

[0012] Further, the horizontal cutting guide includes a horizontal cutting guide plate, which is fixed at a predetermined position of the machine frame. The horizontal cutting guide plate is arranged to match the movement track of the central shaft. The horizontal cutting guide plate gradually protrudes from one end to the middle and gradually recedes from the middle to the other end. In this way, the cutting block motor drives the driving shaft to rotate, and the cutting block shaft group rotates at the same time. When the central shaft moves to the predetermined position, the horizontal cutting cam at the end of the central shaft moves along the horizontal cutting guide plate. When the ball head on the horizontal cutting cam contacts the boss of the horizontal cutting guide plate, the boss of the horizontal cutting guide plate exerts an oblique thrust on the ball head because the horizontal cutting guide plate gradually protrudes from one end to the middle. The oblique thrust can be decomposed into a component force along the circumferential normal of the cutting knife rotation circle and a component force along the central shaft axis. The driving force of the cutting block motor overcomes the component force along the circumferential normal of the cutting knife rotation circle, and the component force along the central shaft axis drives the cutting block shaft to move, thereby driving the cutting knife to move. At this time, the movement of the cutting knife is a compound oblique cutting movement of vertical downward movement and horizontal cutting, so that the rice seedling is cut at a position inside the seedling strip that is away from the seedling feeding unit. After the seedling strip is cut, the cutting knife seat drives the seedling to separate from the strip separating plate, and the seedling enters the seedling guiding device. When the seedling is cut, the middle of the horizontal cutting guide plate gradually recedes to the other end. After the ball head on the horizontal cutting cam separates from the boss of the horizontal cutting guide plate, the cutting block shaft drives the cutting knife to return under the action of the compression spring.

[0013] Further, the cutting device includes a reciprocating motion group and a cutting knife group. The cutting knife group includes a first cutting strip driving member, a second cutting strip driving member, a forward cutting shaft, a cutter disc positioning sleeve, a cutter disc, and a reverse cutting shaft. The forward cutting shaft and the reverse cutting shaft are respectively provided with the cutter disc and the cutter disc positioning sleeve. Adjacent cutter discs are spaced apart by a predetermined position through the cutter disc positioning sleeve. The first cutting strip driving member and the second cutting strip driving member are respectively in transmission connection with the forward cutting shaft and the reverse cutting shaft. The rotation directions of the forward cutting shaft and the reverse cutting shaft are the same as and opposite to the movement direction of the rice pot mat-shaped seedlings. The first cutting strip driving member and the second cutting strip driving member are arranged on the reciprocating motion group. The reciprocating motion group is used to drive the cutting knife group to reciprocate along the cutting strip direction.

[0014] The first slitting driving member and the second slitting driving member are preferably first slitting motors and second slitting motors, and the first slitting motors and the second slitting motors are continuous rotation cutting. The first slitting motors and the second slitting motors drive the forward cutting shaft and the reverse cutting shaft to rotate in opposite directions, and the method of combined cutting is used, so that the cutting force of the cutter on the seedling mat can be offset in the process of cutting the seedling strips, and the displacement of the seedling mat along the seedling strip conveying belt during the cutting of the seedling strips can be prevented, and the precision of the seedling strip conveying can be improved. The cutter also reciprocates forward and backward under the action of the reciprocating group during the cutting process.

[0018] In order to prevent the cutter disc from cutting the seedling mat insufficiently, lifting the seedling mat, the cut seedling being lifted out accidentally, and preventing the cutter disc from reciprocating cutting disturbing the seedling mat, the pressing mat device is arranged on a distance before and after the seedling mat is cut. The distance between the pressed seedling and the seedling feeding table is equal to the thickness of the seedling mat, and the pressed seedling and the seedling feeding table apply a certain force to the seedling mat or the seedling from the front and back sides, which can prevent the seedling mat or the seedling from being lifted out of the seedling feeding table plane, and can also increase the friction between the seedling mat or the seedling and the pressed seedling and the seedling feeding table, prevent the cutter disc from reciprocating cutting disturbing the seedling mat or the seedling, and help to improve the conveying accuracy of the seedling mat or the seedling. The distance between the pressed seedlings is equal to the distance between two seedlings, and the pressed seedling is located between the two seedlings. The width of the pressed seedling is preferably about 20% of the width of the seedling, which can not only press the seedling mat or the seedling, but also prevent the seedling from being damaged.

[0019] The middle of the pressed seedling is provided with a cutter slot, and the top of the cutter disc passes through the cutter slot, which helps the cutter disc to cut the seedling mat and ensures that the seedling mat can be completely cut off to form the required size of the seedling when passing through the cutter disc. By adjusting the position of the pressed seedling adjusting seat, the distance between the pressed seedling and the seedling feeding table can be adjusted to adapt to the thickness of the seedling mat.

[0020] A striping plate is arranged at the rear side of the cutter disc, and the striping guide plate of the striping plate is in the same plane as the cutter disc.

The first cutting motor C15 and the second cutting motor C16 rotate continuously for cutting. The cutter head positioning sleeve C22 and the cutter head C23 are respectively mounted on the forward cutting shaft C21 and the reverse cutting shaft C24. Bearings G2 are installed at both ends of the forward cutting shaft C21 and the reverse cutting shaft C24. The bearings G2 and the retaining rings G6 are installed in the bearing seats G1. The forward cutting shaft C21 and the reverse cutting shaft C24 are driven to rotate by the motor and can also achieve back-and-forth reciprocating motion by the reciprocating motion group C1. Bearing G2 is installed in bearing housing G1, which is installed below the reciprocating motion table C14.

The drive pulley G3 is installed on the first cutting motor C15 and the second cutting motor C16. The driven pulley G5 is installed on the forward cutting shaft C21 and the reverse cutting shaft C24 respectively. The drive pulley G3 and the driven pulley G5 are connected by a synchronous belt G4. The first cutting motor C15 rotates and causes the forward cutting shaft C21 to rotate clockwise, and the second cutting motor C16 rotates and causes the reverse cutting shaft C24 to rotate counterclockwise.

[0068] In specific applications, such as Figure 4, 7 groups of cutter heads C23 are arranged on both sides of the forward cutting shaft C21 and the reverse cutting shaft C24, the cutter heads C23 are separated by a cutter head positioning sleeve C22 at a certain distance, the cutter heads C23 on the two shafts are staggered and rotate in opposite directions, the first cutting motor C15 drives the forward cutting shaft C21 to rotate clockwise through the synchronous belt G4, and the second cutting motor C16 drives the reverse cutting shaft C24 to rotate counterclockwise through the synchronous belt G4. After the carpet seedlings J are sent in, they are conveyed along the first conveying groove A4 and the second conveying groove A5, and are cut into strips by the cutter heads C23 in the conveying process, and the strip-shaped seedlings J pass through the gap in the cutter heads C23.

[0069] The first cutting motor C15 and the second cutting motor C16 drive the forward cutting shaft C21 and the reverse cutting shaft C24 to rotate in opposite directions, and the combined cutting method is used, so that the cutting force of the cutter heads C23 on the seedling carpet can be offset during the cutting of the seedling strips, and displacement of the seedling carpet along the seedling strip conveying belt B3 during cutting can be prevented, and the seedling strip conveying accuracy can be improved. The cutter heads C23 also reciprocate forward and backward under the action of the reciprocating motion group C1 during cutting.

[0070] After the whole machine is operated, the cutter heads C23 continuously cut strips under the action of the first cutting motor C15 and the second cutting motor C16, the seedling feeding device waits for the signal of the sensor E9, and is driven to operate by the control system. After the control system receives the signal of the sensor E9, the seedling feeding motor B1 is driven to rotate accurately by a certain angle, so that the seedling strip conveying belt B3 and the seedling carpet conveying belt B9 are moved, and the seedling carpet and the seedling strip are accurately conveyed by one unit. When the seedling strip conveying is completed, the linear driving part C11 starts to move, the linear driving part C11 moves the cutter heads C23 forward to cut the seedling carpet, and after the cutting is completed, the linear driving part C11 moves the cutter heads C23 back to the original position. The forward and backward reciprocating movement of the cutter heads C23 makes the seedling strips cut into strips before being conveyed, so that the seedling strip conveying resistance is reduced, and the seedling strip conveying accuracy is improved.

[0071] In the embodiment of the application, as Figure 5 , the reciprocating motion group C1 includes a linear driving part C11, a push rod C12, a base C13 and a reciprocating motion platform C14, the linear driving part C11 and the base C13 are fixed on the rack A, the first cutting driving part and the second cutting driving part are arranged on the reciprocating motion platform C14, one end of the push rod C12 is in transmission connection with the linear driving part C11, and the other end penetrates through the base C13 and is connected with the reciprocating motion platform C14.

[0072] Specifically used in the process, as Figure 5A sliding pin C17 is provided on the reciprocating motion table C14, and a shaft hole C18 matching the sliding pin C17 is provided on the base C13. The sliding pin C17 passes through the shaft hole C18. During the movement, the base C13 and the reciprocating motion table C14 are positioned and guided by the shaft hole C18 and the sliding pin C17. The push rod C12 is connected to the reciprocating motion table C14 by a pin G7. The linear drive C11 pushes the push rod C12 to reciprocate, which in turn drives the reciprocating motion table C14, thereby driving the cutter head C23 to reciprocate, completing the strip cutting operation.

[0073] During the cutting process, the cutter head C23 reciprocates back and forth under the action of the linear drive component C11. Specifically, after sensor E9 receives a signal, there is a delay, and then the linear drive component C11 controls the push rod C12 to retract. Push rod C12 retracts to its short limit and then reverses direction to extend to its long limit, before waiting for a signal from sensor E9 to enter the next cutting cycle. The total time for push rod C12 to retract to its short limit and then reverse direction to extend to its long limit is less than one cutting cycle.

[0084] As Figures 7-10 , the two ends of the center shaft E32 are installed on the cutting block side plate E4 through the rotating pair respectively, and the other side of the center shaft E32 is also fixedly installed with the connecting rod E7 through the connecting rod shaft hole E71, the connecting rod E7 is installed together with the eccentric side plate E6 through the connecting rod shaft E72 and the connecting rod installation hole E61 of the eccentric side plate E6, and the center shaft E32, the cutting block side plate E4, the connecting rod E7 and the eccentric side plate E6 form an eccentric rotating system, so that the center shaft E32 does not rotate around its axis while rotating around the driving shaft E5, and the specific performance is that the guide groove E321 is arranged on the center shaft E32, and the plane of the guide groove E321 is always perpendicular to the plane of the seedling feeding table A3 on the frame A1.

[0085] So set up, as Figure 10, eccentric side plate E6 rotates around the auxiliary wheel center O1, the cutting side plate E4 rotates around the drive shaft center O2, the eccentric distance between the auxiliary wheel E8 center and the drive shaft center O2 is L2, the distance between the connecting rod shaft center O3 and the cutting knife shaft E33 center is the length L1 of the connecting rod E7, L1 is equal to L2, the distance between the auxiliary wheel center O1 and the connecting rod shaft center O3 is equal to the distance between the drive shaft center O2 and the cutting knife shaft center O4. Therefore, the auxiliary wheel center O1, the drive shaft center O2, the connecting rod shaft center O3 and the cutting knife shaft center O4 form a parallelogram mechanism. Since the auxiliary wheel E8 is fixedly installed on the cutting block support A6 through the eccentric wheel mounting plate, when the mechanism rotates with the drive shaft center O2 as the fixed point, the cutting knife E34 always rotates in the same posture. As shown in Figure 10 , in the embodiment of the present scheme, the auxiliary wheel center O1 is directly below the drive shaft center O2, and when the cutting knife E34 is installed, the cutting knife plane is parallel to the axis of the connecting rod E7. No matter how many degrees the cutting block device E rotates, the cutting knife plane of the cutting knife E34 is always parallel to the line between the auxiliary wheel center O1 and the drive shaft center O2 (as shown in Figure 10 , the dashed line after the cutting block device E rotates α degrees).

[0086] In the embodiment of the present application, as shown in Figures 7-9 , the cutting knife shaft group E3 further comprises a transverse cutting cam E31 and a reset member, the transverse cutting cam E31 is provided with a ball head E311 and a connecting hole, the center shaft E32 is a hollow shaft, a guide groove E321 is arranged on the center shaft E32 along the axial direction, the reset member is sleeved on one end of the center shaft E32, and the other end is provided with the transverse cutting cam E31, the transverse cutting cam E31 is connected with the cutting knife shaft E33 through a connecting piece, the connecting piece passes through the connecting hole and the guide groove E321, and the two sides of the reset member abut against the cutting knife shaft E33 and the cutting side plate E4 respectively. When the cutting knife shaft E33 rotates to a predetermined position, the transverse cutting guide pushes the transverse cutting cam E31 to move along the guide groove E321 and drives the cutting knife shaft E33 to move transversely, and the reset member is used to drive the cutting knife shaft E33 to reset to the initial position when the transverse cutting guide has no force on the transverse cutting cam E31.

[0087] As shown in Figures 7-9The cutting block driving member is preferably a cutting block motor E1, the reset member is preferably a compression spring E35, the connecting hole is preferably a bolt hole E312, the connecting member is a bolt G8, the central shaft E32 is a hollow shaft, the central shaft E32 is provided with a guide groove E321, the outer circle of the transverse cutting cam E31 is installed with the inner hole of the central shaft E32 through sliding fit, the bolt hole E312 of the transverse cutting cam E31 is fixedly connected with the cutting block cutter shaft E33 through the bolt G8, the bolt G8 connecting the transverse cutting cam E31 and the cutting block cutter shaft E33 penetrates the guide groove E321 on the central shaft E32, and the axis of the compression spring E35 is installed on the central shaft E32 close to the auxiliary wheel E8, and the compression spring E35 is supported between the cutting block cutter shaft E33 and the cutting block side plate E4 on the two sides. When the transverse cutting guide plate E2 pushes the transverse cutting cam E31 to move, the transverse cutting cam E31 can drive the cutting block cutter shaft E33 to move transversely along the guide groove E321, so that the transverse movement of the cutting knife E34 is realized. When the pushing force of the transverse cutting guide plate E2 on the transverse cutting cam E31 disappears, the cutting block cutter shaft E33 returns to the initial position, so that the cutting knife E34 returns to the initial position.

[0088] In the embodiment of the present application, as shown in Figure 9 , Figure 12 and Figure 13 , the cutting block motor E1 drives the driving shaft E5 to rotate, the driving shaft E5 drives the cutting block side plate E4 to rotate, the cutting block side plate E4 drives the cutting block cutter shaft E33 group E3 to rotate, and then drives the cutting knife E34 to move. Under the action of the compression spring E35, the cutting knife E34 is arranged between the two seedlings J in the initial position. When the cutting knife E34 moves along the cutting knife E34 return circle, the cutting knife E34 enters the seedling mat from between the two seedlings J. When the cutting knife E34 contacts the seedling mat, the transverse cutting cam E31 is driven to move transversely under the action of the transverse cutting guide, and the cutting knife E34 moves transversely to the other side under the action of the transverse cutting cam E31, so that the cutting knife E34 moves transversely while being vertically cut to realize oblique cutting.

[0089] In the embodiment of the present application, as shown in Figure 7 , the transverse cutting guide includes a transverse cutting guide plate E2, the transverse cutting guide plate E2 is fixed at a predetermined position of the rack A, the transverse cutting guide plate E2 is matched with the movement track of the central shaft E32, and the transverse cutting guide plate E2 is gradually convex from one end to the middle and gradually concave from the middle to the other end.

[0090] As shown in Figure 9 , 10As shown in Fig. 13, the cutting motor E1 drives the driving shaft E5 to rotate, and the cutting knife shaft group E3 rotates, and the center shaft E32 moves to a predetermined position, and the transverse cutting cam E31 at the end of the center shaft E32 moves along the transverse cutting guide plate E2. When the ball head E311 on the transverse cutting cam E31 contacts the convex platform of the transverse cutting guide plate E2, the convex platform of the transverse cutting guide plate E2 generates an oblique thrust force on the ball head E311 due to the gradual convexity of the transverse cutting guide plate E2 from one end to the middle. The oblique thrust force can be decomposed into a component force on the circumferential normal line of the cutting knife E34 rotation circle and a component force along the axis of the center shaft E32. The driving force of the cutting motor E1 overcomes the component force on the circumferential normal line of the cutting knife E34 rotation circle, and the component force along the axis of the center shaft E32 pushes the cutting knife shaft E33 to move, and further pushes the cutting knife E34 to move. At this time, the movement of the cutting knife E34 is a compound oblique cutting movement of vertical downward and transverse cutting, so as to achieve cutting of the seedling strip at a position away from the seedling strip cutting unit. After the seedling strip is cut, the seedling J is pushed off the dividing plate D2 by the knife seat of the cutting knife E34, and the seedling J enters the seedling guiding device F. When the seedling J is cut, the middle part of the transverse cutting guide plate E2 gradually recedes to the other end, and the ball head E311 on the transverse cutting cam E31 is separated from the convex platform of the transverse cutting guide plate E2, and under the action of the compression spring E35, the cutting knife shaft E33 drives the cutting knife E34 to reset.

[0091] In the embodiment of the present application, as shown in Figure 1 、 Figure 2 and Figure 11 , the seedling guiding device F comprises a seedling guiding bottom plate F1, a seedling guiding partition plate F2 and a seedling guiding plate F3. The seedling guiding partition plate F2 is arranged on the seedling guiding bottom plate F1 and forms a seedling guiding groove with the seedling guiding bottom plate F1. The seedling guiding plate F3 is arranged in a predetermined direction at the lower part of the seedling guiding partition plate F2 and is connected with the seedling guiding partition plate F2. The cut seedling J passes through the seedling guiding groove and is thrown downward in a predetermined direction by the seedling guiding plate F3.

[0092] In this way, after the seedling J is cut by the cutting device E, it falls downward into the seedling guiding device F and becomes an independent seedling guiding unit through the shunt of the seedling guiding partition plate F2. The seedling J falls into different seedling guiding grooves and is grouped and thrown for transplanting under the action of the seedling guiding plate F3. The width of the seedling guiding groove corresponds to multiple seedlings J.

[0093] In order to improve the efficiency of throwing seedlings, the basic unit is grouped according to the number of cutting knife shaft groups E3, that is, the seedling guiding unit. The integer multiple of the basic unit (i.e. the number of throwing seedling rows) is a group of throwing seedling units H, and finally the whole machine is composed of integer multiple throwing seedling units H. The machine optimizes a set of 15 seedling throwing seedling units H formed by 3 groups of cutting knife shaft groups E3 and 5 groups of seedling guiding units according to the comprehensive operation speed, the existing seedling raising specifications, the throwing seedling row spacing and other parameters. One throwing seedling unit H throws 5 rows of seedlings, and the whole machine is composed of two groups of throwing seedling units H, forming a throwing seedling machine that can throw 10 rows at a time. In addition to the present scheme, the number of cutting knife shaft groups E3 can also be 4, 5, 6, the seedling guiding unit can be 3, 4, 6, and the throwing seedling unit H can be 1, 3, 4, 5, 6 and other combination schemes.

[0094] The above only describes the preferred embodiments of the present application, and it should be noted that those skilled in the art can make several improvements and refinements without departing from the principles of the present application, and these improvements and refinements should also be considered within the scope of protection of the present application.
